Description

Technical Field

[0001] The utility model relates to the field of waste crushing, in particular to a plastic waste crushing device. Background Art

[0002] Plastic waste crushing is an important part of the plastic recycling and processing process. It involves physically crushing the collected waste plastic products through mechanical equipment such as crushers to convert them into smaller fragments or particles.

[0003] The existing plastic waste crushing usually uses a conveyor belt to send the plastic waste to a crushing area, and the crushed waste enters a collection area, and then is collected manually. However, there may be metal in the plastic waste, and crushing the metal may cause damage to the crushing mechanism, thereby affecting the crushing efficiency. At the same time, some plastics need to be crushed repeatedly before they can be crushed. The crushing process of only passing through the crushing mechanism once cannot achieve complete crushing. When crushing waste that is difficult to crush, the waste needs to be repeatedly put into the crushing mechanism, which is time-consuming and inconvenient.

[0004] Therefore, it is necessary to design a plastic waste crushing device that can crush waste twice, collect metals without crushing them, and automatically collect crushed waste, thereby saving time and improving crushing efficiency. Utility Model Content
