　　Here we will introduce some basic knowledge about traditional watches.Under people’s attention mechanical watch Finally grow into what people need, born for the market and come for the demand. https://www.supertimewatch.com/

　　watch basics

　　1. Watch styles and functions

　　Watch styles and functions. Watches are divided into two categories: mechanical and quartz. The most common mechanical watch has an automatic calendar function.

　　2. Quartz watch vs. mechanical watch

　　Which is better, a quartz watch or a mechanical watch? They both have their pros and cons, regardless of value. Quartz watches can be expensive, while mechanical watches can be cheap. Generally speaking, mechanical watches are more ornamental, while quartz watches are more accurate and easy to use. There are three ways to distinguish them.

　　(1) Look at the logo. Automatic watches will have the letters AUTOMATIC or SELF-WINDING.

　　(2) Look at the movement of the second hand. A quartz watch jumps one second at a time, while a mechanical watch has the second hand continuously moving across the dial.

　　(3) Check whether it can be wound or whether there is a sound of the automatic rotor spinning.

　　3. The indication function of the watch

　　The hands and dial are used to indicate the time, and there are also windows with numbers. The window type is mostly used for calendars. The so-called “big calendar” has two windows, which display the tens and the digits of the date respectively.

　　4. The flyback and retrograde forms of the watch hands

　　They do not rotate in a clockwise circle. The flyback is the characteristic of the chronograph returning to zero, while the retrograde is when the hands move in a “fan shape”. The retrograde movement in a fan shape is rather strange, as it automatically returns to zero after completing the full range.

　　5. Chronograph watch

　　Commonly known as “three needles and three eyes”, it also has three crowns. 1. Most of the chronograph stopwatches currently use a double-button type, with the two buttons usually at 2 and 4 o’clock. The 2 o’clock button controls the “start and stop” function, and the 4 o’clock button controls the “reset” function. 2. The operation method used is usually the process of “start—stop—-reset” or “start—stop—-start—stop—reset”. The stopwatch function must be stopped before pressing the reset button. 3. The single-button stopwatch is relatively simple, with one button controlling the “start—stop—-reset” function. Please note that after each button is pressed, it must be reset before it can be pressed a second time.

　　6. Moon phase display

　　The moon phase is actually a lunar calendar, indicating the cycle of the moon’s waxing and waning. The sun, moon and stars are the most intuitive celestial bodies, but the moon phase is related to latitude. Design principle: The moon phase function is often placed in a semicircular window of a special shape, which includes a semicircular arc and two small arcs. This carefully designed shape combined with the moon on the moon phase disk can accurately tell us the shape of the moon at the beginning or end of a cycle. Operation principle: The moon phase displays the state of the moon on the moon phase disk based on a 29.5-day cycle. There are two moons on this moon phase disk, with 59 teeth on the edge. After being pushed by the transmission wheel, the moon phase wheel advances one tooth every day, and the changes in the moon phase can be displayed on the dial in time. The 59-tooth moon phase wheel comes from the average value of the moon phase waxing and waning every 29.5 days. Since the precise rotation period of the moon is 28 days, 12 hours, 44 minutes and 2.9 seconds, the error of the moon phase display will reach 24 hours every approximately 33 months. There is usually a moon phase adjustment button on the watch case, and the moon phase display is relatively independent of functions such as chronograph and perpetual calendar.

　　Working principle of automatic hemming equipment for injection molding:At first, Pickleball welding equipment It developed out of control and gradually opened up a sky of its own. https://ydjshangyuzn.com

　　Preparation of racket embryo: Prepare the racket embryo with the racket body and handle in advance through a specific process (such as molding, etc.).

　　Mould installation and positioning: Accurately install the racket mold at the corresponding position of the injection molding machine to ensure that the key parts such as the mold cavity and the injection molding system are accurately matched.

　　Feeding and melting: Add plastic particles to the hopper of the injection molding machine, and gradually melt the plastic particles into a liquid state through the heating system of the injection molding machine (such as resistance heating, etc.), and convey them forward under the push of the screw, etc.

　　Injection stage: After reaching the appropriate fluidity and other states, the liquid plastic is injected into the mold cavity where the racket embryo has been placed under a certain pressure, and the liquid plastic will flow and fill along the outer peripheral side of the racket embryo.

　　Cooling and shaping: The plastic entering the mold cavity is cooled quickly through the mold’s own cooling channel (such as cooling water), and the plastic gradually solidifies and tightly wraps around the outer peripheral side of the racket embryo to form a rim.

　　Demolding: The mold is opened by the mold opening mechanism (such as hydraulic or mechanical drive, etc.), and the finished racket with rim is removed from the mold by the ejection mechanism (such as ejector rod, etc.).

　　Working principle of hot pressing rimming automatic equipment (hypothetical situation):

　　Edge material delivery: The pre-prepared rimming material (such as rubber strips, TPU strips, etc.) is released from the unwinding device at a certain speed and tension, and transported to the working area through conveyor tracks or rollers.

　　Racket positioning: The pickleball racket is placed on a specific working platform through a mechanical arm or conveyor belt, and the racket position is ensured to be accurate through positioning mechanisms (such as clamps, sensor induction, etc.).

　　Preheating: Before the hemming contacts the racket, the hemming material and/or the hemming area of the racket are preheated. The material can be softened by infrared heating, hot air heating, etc. to facilitate subsequent bonding.

　　Hot pressing bonding: The hemming material is pressed tightly against the edge of the racket by using a hot pressing head (with a certain shape and temperature control) to make the hemming material tightly bonded to the edge of the racket under the action of pressure and temperature.

　　Cooling and curing (if necessary): After hot pressing, the hemming material is quickly cured and shaped on the racket by air cooling or other cooling methods.

　　Trimming (if necessary): Use a knife or laser to cut off excess hemming material.

　　container shipping

　　1. Low price trap

　　The quotation issue is an important aspect of the international express freight forwarding industry. Many consumers are often attracted by some low quotations when choosing freight forwarding companies.

　　In order to attract consumers, some unscrupulous merchants will deliberately lower prices, or even use the banner of “free shipping”. However, in actual operations, these merchants often charge additional fees through various means, such as packaging fees, insurance fees, tariffs, etc., which results in consumers ultimately paying much more than expected.

　　Therefore, when choosing international express shipping services, consumers must carefully read the contract terms, understand all possible fees, and choose reputable merchants.

　　container shipping

　　2. Packaging issues

　　Some freight forwarding companies often use non-standard packaging methods to save costs or improve efficiency during the packaging process. This may not only cause damage to the goods during transportation, but also affect the customs clearance and delivery of the goods.

　　In addition, some companies deliberately increase the size of packages and fillers to increase shipping costs. Therefore, when choosing a shipping company, consumers should pay attention to its packaging method and attitude to ensure that the goods are properly packaged and protected.

¡¡¡¡Prediction

¡¡¡¡

¡¡¡¡According to legend, professional umbrella can also predict a person¡¯s luck. If an umbrella falls on the ground, do not pick it up yourself, otherwise bad luck will come. If you open it on a sunny day, it will be a bad omen. Do not open it indoors. It is best to open it indoors.

¡¡¡¡

¡¡¡¡Code words

¡¡¡¡

¡¡¡¡The UK began using umbrellas only in the 18th century. The Bernas umbrella was once a special item for women, which expressed women¡¯s attitude towards love. Holding the umbrella upright means being faithful to love; holding the open umbrella in the left hand means holding the umbrella tightly. Slowly shaking the umbrella means lack of confidence or distrust; leaning the umbrella on the right shoulder means not wanting to see you again.

¡¡¡¡

¡¡¡¡Social significance

¡¡¡¡

¡¡¡¡In ancient China, umbrellas symbolized power for emperors, generals, and dignitaries, as clearly recorded in the ¡°Book of Jin¡± and ¡°Yufuzhi¡± in Zuo Zhuan. The records show a strict hierarchy associated with their use. The materials, colors, and sizes of umbrellas are like the black gauze on the head and the court dress on the body, which also distinguish the official positions. For example, in the Han Dynasty, it was stipulated that the nine ministers and three officials who ate more than 2,000 stones of millet used black. The officials who were not allowed to wear black clothes were all allowed to wear blue. Therefore, in ancient times, the sedan chairs or cars that the emperors or high officials rode on when they went on tours all had umbrella covers to show that they ¡°shaded the people.¡± Therefore, this kind of umbrella is also called ¡°cool umbrella¡±, ¡°Luo umbrella¡±, ¡°all people¡¯s umbrella¡±, and ¡°Huagai¡± in written language.

¡¡¡¡Two-fold umbrellas

¡¡¡¡

¡¡¡¡T151 Bronze Chariot and Horses in the Mausoleum of Qin Shihuang, and the ¡°Huagai¡± in T131 A Thousand Miles Alone, are both symbols of the identity of the umbrella user. The most magnificent and fully expressed use of umbrellas in ceremonials may be the ¡°Ming People Going Out on Police and Entering the Imperial Court¡± issued by Taiwan Province. Two five-piece sheets also have partial enlarged pictures. In the second stamp of the imperial court, there are five ¡°Luo umbrellas¡± in red, green, yellow, blue and white, which are colorful. In the third and fifth stamps of the ¡°Police Outing¡±, there are some symmetrical left and right temporarily closed and carried on the shoulders, and some are open in the middle and marching, which are bustling and magnificent. Because umbrellas symbolize wealth and honor, there is also a custom of holding umbrellas in folk weddings in the East. This is vividly depicted in the folk wedding stamps issued in Macau and North Korea.

¡¡¡¡

¡¡¡¡The umbrella is not only a decoration for government ceremonies, but also a common prop in opera, singing and dancing, and acrobatics. The first stamp of the ¡°Legend of the White Snake¡± issued by Taiwan Province in 1983 reflects the scene of ¡°borrowing an umbrella from West Lake¡±, which is this umbrella. The imperial court also used umbrellas as props. Many Chinese and foreign stamps reflect national folk art that features umbrellas as central props.
