　　Working principle of automatic hemming equipment for injection molding:Today, people are interested in Pickleball welding equipment There are also many dependencies, and the expectations for products are getting higher and higher. 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.

　　The development of optical fiber communication technology has greatly promoted the development of information transmission and played a vital role in promoting the arrival of the information age. Based on the discussion of optical fiber communication and its related concepts, this paper focuses on the development, application and future trend of optical fiber communication technology, and summarizes the significance of this research, so as to complete the research on the development, application and prospect of optical fiber communication technology.know optical cable Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://www.fibercan-network.com/

　　Optical fiber is an important medium, which can realize low loss of light propagation, which is of great significance for restoring input information and realizing low loss transmission of information. Because the development of optical fiber communication technology in China is in its infancy, there are still some shortcomings in its development. The existence of these problems has greatly hindered the development of optical fiber communication technology. Based on the understanding of the current development situation of optical fiber communication technology in China, the author will discuss the development, application and future development trend of optical fiber communication technology in order to provide practical and feasible reference suggestions for relevant scholars and staff in the research of optical fiber communication technology.

　　Optical fiber communication and its related concepts

　　Optical fiber consists of core layer, outer layer and cladding, in which the refractive index of core layer is greater than that of cladding, and silicide is generally used. When light enters the optical fiber, because the refractive index of the core medium is greater than that of the outer layer, when the incident angle meets certain conditions, total reflection will occur, and the incident light will not be refracted at this time, so that the transmission of optical energy can be close to 100%. The main purpose of the outer layer is to improve the toughness of optical fiber and reduce the external damage to optical fiber. Optical fiber communication is a communication technology based on the above characteristics of optical fiber. It mainly uses light waves as carriers to load information onto light waves, and then realizes the effective transmission of information through low-loss transmission of light waves in optical fiber. It can be said that the development history of optical fiber communication is very rich. Since 1966, scholars have studied silica optical fiber, which has played an important role in promoting the development of optical fiber communication and opened a precedent for the research and development of optical fiber communication technology.

　　Subsequently, with the continuous development of optical wave amplification technology, optical fiber amplifier came into being, which is of great significance to realize optical amplification of optical fiber optical wave signals and improve the transmission efficiency of optical wave information. At present, optical fiber communication technology mainly includes five aspects: signal is output, signal light wave coupling, optical signal transmission and amplification, light wave signal dissociation and signal input. The main features of optical fiber communication technology are as follows. First of all, we know that perfect monochromatic light waves do not exist, and all light waves contain a little bandwidth.

　　When the bandwidth value is less than the resolution limit of human eyes, what we see is the so-called monochromatic light waves. The wider the frequency band of light wave, the greater its information content. Compared with copper wire, optical fiber medium has a better transmission bandwidth, which can greatly enhance the information capacity, which is of great significance for the transmission of big data. Secondly, because the total reflection of light is realized, the loss of optical information transmission can be greatly reduced. Furthermore, Shi Ying materials are not active in chemistry, are not easy to be corroded, and have good insulation properties, which can greatly avoid the influence of lightning, water dew and radiation, which is of great significance for ensuring the life of optical fibers. In addition, the optical fiber is flexible and easy to lay, which reduces the process difficulty and cost, and is of great significance for realizing high-security transmission.

　　The headrest is an important part of the car seat, which can effectively protect the driver and passenger¨s head and neck from impact. The correct headrest height can ensure that the headrest can play the greatest protective role when the vehicle is hit violently.

　　. How to adjust the headrest height

　　First, the driver should adjust the car headrest height to be flush with the head. This is because the softest and most protective part of the headrest is in the middle of the headrest. Only when the headrest height is flush with the head can the headrest effectively protect the head and cervical spine.

　　Next, the driver should ensure that the distance between the back of the head and the headrest is as small as possible. From a physical point of view, the smaller the distance between the back of the head and the headrest when the car is hit, the greater the cushioning effect of the headrest on the head and neck. This distance should not exceed 4 cm at most, which is equivalent to the width of two fingers side by side.

　　In addition, the driver should also pay attention to the way the headrest is fixed. Some car headrests can be adjusted by rotating or sliding, while others need to be adjusted by disassembly and reinstallation. Either way, the driver should ensure that the headrest is firmly fixed to the seat to prevent it from shifting in the event of a vehicle collision.
