Description

Technical field:

[0001] The invention relates to the technical field of lunch box production and processing, and in particular to a device for crushing easily degradable lunch box raw materials and a method for using the device. Background technology:

[0002] Biodegradable lunch boxes are food containers made of biodegradable materials. Due to the relatively high cost of biodegradable materials, the leftover materials of the formed raw materials will be crushed and reused during the production of lunch boxes.

[0003] The prior art patent CN216727603U discloses a new type of grinder based on food lunch box processing, which relates to the technical field of grinders. After the lunch box is crushed, it is screened in time to avoid the appearance of fragments of different sizes mixed together during crushing, which need to be classified before use. At the same time, it is convenient to operate, increase work efficiency, and reduce labor. After the scraps of lunch box processing are crushed, the above scheme can be screened to facilitate the reuse of lunch box raw materials. However, in the process of crushing the scraps of lunch box production, the crushing tool holder is mainly installed by fixing with multiple bolts. When the position of the cutting edge needs to be adjusted, it needs to be repeatedly disassembled and fixed and adjusted. When the position of the cutting edge is not suitable, the problem of collision with the blade or poor crushing efficiency may occur, which increases the energy consumption of the crushing process. In addition, the main shaft of the tool holder is easily aged by high-speed rotation for a long time, which is inconvenient for maintenance. Summary of the invention:
