On the PET product production line, PET particles are often first made into a sheet structure, and then compression molding is performed on the sheet structure to form the corresponding PET products. The actual utilization rate of the sheet structure PET can only reach 50%, so a large amount of scraps will be generated, and these scraps will be recycled and piled together by the operators. After reaching a certain amount of piles, the operators will uniformly put them into the crushing equipment to make particles, so that they can be put back into the production line later. It can be seen that not only a large warehouse is needed for the dumping of scraps, but also the recycling of scraps, the placement of crushing equipment, and the re-introduction of the production line also require the joint operation of multiple operators, which has high labor costs, is time-consuming and labor-intensive, and has low efficiency.

[0014] The present invention is further described below with reference to specific embodiments. Figure 1 :
[0015] A waste recovery and reprocessing system for a PET product production line includes more than one PET product production line and PET crushing devices 1 corresponding to the number of PET product production lines, the waste end of each PET product production line is connected to the feed end of the corresponding PET crushing device 1, the discharge end of each PET crushing device 1 is connected to the feed end of a crushing storage container 2 through a cyclone feeder, and the discharge end of the crushing storage container 2 and the discharge end of a raw material container 3 filled with PET particles are connected to the batching end of each PET product production line through a cyclone feeder. In this embodiment, there are three PET product production lines, and the waste in the crushing storage container 2 and the PET particles in the raw material container 3 can be put into the batching end of the corresponding PET product production line in a certain proportion according to actual processing requirements.
[0016] The utility model has a high degree of automation. With the help of a cyclone feeder, the waste particles crushed by the PET crushing device 1 are automatically transported to the crushing storage chamber, and then with the help of the cyclone feeder, the waste particles and the PET particles in the raw material container 3 are transported to the batching end of the PET product production line, which effectively saves a lot of labor costs and has high efficiency.
[0017] Furthermore, in the present embodiment, the specific components of the PET product production line are as follows: the PET product production line includes a batching and mixing container 4, a PET crystallizer 5, a sheet extrusion production equipment 6, and a product production equipment 7 in sequence along the production direction; the discharge end of the crushing storage container 2 and the discharge end of the raw material container 3 are both connected to the feed end of the batching and mixing container 4; the discharge end of the batching and mixing container 4 is connected to the feed end of the PET crystallizer 5; the discharge end of the PET crystallizer 5 is connected to the feed end of the sheet extrusion production equipment 6; the discharge end of the sheet extrusion production equipment 6 is connected to the feed end of the product production equipment 7; the finished product end of the feed end of the product production equipment 7 is connected to the outside, and the waste end is connected to the feed end of the corresponding PET crushing device 1.
[0018] That is, the working principle of the PET product production line in the utility model is: PET particles are automatically transported from the raw material container 3 to the batching and mixing container 4 through the cyclone feeder, and the PET particles and waste particles are mixed according to a certain ratio, and the mixed particles are put into the PET crystallizer 5 for crystallization treatment, and the mixed material after crystallization treatment is put into the sheet extrusion production equipment 6 for sheet process production, and the obtained sheet structure is then produced by the product production equipment 7 to obtain the required PET product, and in this embodiment, the PET product is a disposable cup. The scraps generated by the product production equipment 7 after production are automatically transported to the PET crushing device 1 along with its production and transportation to be crushed into waste particles.
[0019] Among them, considering the product characteristic requirements of the actual PET products, the PET particles need to be mixed with other auxiliary materials and additives, so the PET product production line also includes an auxiliary material and additive container 8, and the discharge end of the auxiliary material and additive container 8 is connected to the feed end of the sheet extrusion production equipment 6. Therefore, the waste particles produced from the PET crushing device 1 are particles of mixed PET and auxiliary materials and additives, so a certain amount of auxiliary materials and additives can be added to the feed end of the sheet extrusion production equipment 6 according to the ratio of the waste particles and the PET particles put into the batching mixing container 4.
[0020] Furthermore, considering that different PET products have different process requirements, the proportion of waste particles required is also different accordingly. Therefore, in order to be able to add waste particles to the crushing storage container or take out excess waste particles from the crushing storage container, a return material compensation container 9 and a return material storage component 10 are also included. The return material compensation container 9 is filled with PET particles, and the discharge end of the return material compensation container 9 is connected to the feed end of the crushing storage container 2 through a cyclone feeder. The crushing storage container is provided with a return port, and the return material storage component 10 is connected to the return port of the crushing storage container. Among them, the return material storage component 10 can be a common bagging and baling machine on the market, or it can be directly a storage container, and the excess waste particles in the return material storage component 10 can be returned to the crushing storage container through the return material compensation container 9 when the next PET product needs more waste particles.
[0021] In addition, in order to improve the degree of automation of the utility model and reduce manual intervention of operators, the discharge end of the ingredient mixing container 4 and the feed end of the PET crystallizer 5, the discharge end of the PET crystallizer 5 and the discharge end of the auxiliary material and additive container 8 and the feed end of the sheet extrusion production equipment 6 are all connected through a cyclone feeder.
