The most widely used form of delivery in catering shops is to use the fast food box produced by the lunch box machine for packaging, and then take delivery. This is also the packaging product used in many catering industries including the fast food industry. As a lunch box machine, the technology used in it is also the main processing method of sheet machinery. Extrusion molding and press forming are the main processing forms of this kind of lunch box machine. As a main production equipment for fast food boxes, in fact, there is already a machine for automatic production, which provides a certain driving force for the lunch box machine through a dedicated motor, so that the machine can play a certain automatic production.
         Moreover, compared with the general general thermoforming machine, the heating and extrusion molding of the lunch box machine is simpler, and the lunch box machine is the main form for the equipment for producing the fast food box. This kind of machinery has a relatively large role and significance for fast food shops and even the catering industry, and is a driving force for the development of the industry.

         The lunch box machine, as the name suggests, belongs to a kind of equipment for producing boxware. The box produced by this kind of machinery is generally used in the catering industry to produce plastic boxes as the main products. As a plastic box, the most typical one is the disposable plastic box. This kind of product is mainly used in the catering industry, for the packaging function of take-out and the role of the food store in the fast food shop. When it comes to the machinery that produces plastic boxes, in fact, fast-food boxes are still the main production products. Because such plastic boxes can be used in fast food stores or as the main products used in other catering industries, It is well received by consumers.
         At present, the mainstream food and beverage packaging products in the city, and the production of the lunch box machine is actually through the processing of the plastic material, hauling it onto the processing device, and molding the plastic box by means of heating molding and mold fixing. After the molding, it is cooled, and after cooling, the lunch box machine is subjected to fine processing of the final process by extrusion to completion. This is the main production method of this product.

         The current lunch box machine is mainly used to produce disposable plastic fast food boxes, and as a kind of more used products in the current urban catering industry, we actually use it in many times. Most of the current takeaways use this kind of fast food box for packaging, whether it is a snack box in the form of a foam or a hard plastic box, which is now more common. When it comes to such fast food boxes, it is mainly processed and manufactured using a lunch box machine. When it comes to the production of lunch box machines, the auxiliary devices play an important role. The internal coupling is one of them. Introduce this coupling device.
         The couplings that are adjusted to the lunch box are divided into two categories: the first one is rigid, and the coupling transmits the shock that may occur in the transmission when transmitting torque from one part to the other; the second is Rao Sexually, this type of coupling relieves the shock when transmitting torque. The clutch represents an individual form of the coupling that allows the shaft to be separated or coupled without disassembly during its operation. These types of clutches are classified into two types: toothed and frictional. In some cases, it is necessary to use a safety coupling when transmitting torque that does not exceed the specified value, or to construct a friction coupling or a fixed coupling.

         The demand for fast food boxes in the fast food industry is rising year by year. In many cases, the amount of business in fast food restaurants is not as good as the number of order foods for takeaway. From this point, it can be seen that the demand for quick and convenient take-out, saving time and worry-free fast food is very big.
         For the fast food market, it is one of the main forms of the catering industry in the city, and it is also a relatively fast-growing industry in recent years. For the industry itself, it is an industry with market prospects.
         In this fast-developing society, the pace of people's work and life is constantly accelerating, and the food and leisure after work, fast food has become their best choice. They often order fast food take-out after work, which is convenient and practical, and fast food delivery requires the use of fast food boxes, which are produced and processed through the lunch box machine.
         The use of the lunch box machine is undoubtedly a certain convenience brought by the delivery of the fast food industry. At present, the use of plastic fast food boxes is gradually replacing the previous plastic bags and paper cups with fast food packaging, which will make us feel fast food. The more formalization of the industry makes us feel that food is cleaner and safer, allowing us to have a more assured diet. This is the “improvement” of the lunch box machine for the fast food industry.

          At present, we often use a variety of disposable plastic products in our lives, but there has not been a shortage of supply, mainly because the current plastic molding machinery production efficiency is very high, and when it comes to molding equipment, it has to Mention this typical plastic molding machine - the lunch box machine. The lunch box machine is mainly used to produce disposable snack boxes, which are in the meal.
 The beverage industry is especially indispensable in the fast food industry.
          Most of the current plastic processing and production machinery adopts a standardized production mode, especially some mechanical equipment for mass production of plastic products. These machines are standardized in the production of molds to produce large quantities of identical products, which is the main form of production of disposable snack boxes. In many cases, the lunch box machine is made by heating and then using the principle of mold shaping to produce plastic products. It can be seen that this kind of machinery is excellent in both production and technology itself.
         With the continuous advancement of technology and technology, the performance of lunch box machines is constantly improving. Nowadays, many new technologies have emerged, such as ultrasonic connection technology, high-frequency control technology, and multi-arc ion technology.
