Description

Technical Field

[0001] The utility model relates to the relevant field of plastic shredders, in particular to an auxiliary discharging device of a plastic shredder. Background Art

[0002] Plastic shredder is a widely used equipment in the plastic recycling industry, mainly used to cut waste plastic products into small pieces for further processing and utilization. However, there are some problems in the working process of traditional plastic shredders, such as plastic fragments easily blocking the machine and affecting work efficiency. In order to solve this problem, people have designed auxiliary discharge devices.

[0003] The auxiliary discharging device of the existing shredder, such as the Chinese utility model patent with patent number: CN202122182468.5, discloses "A plastic shredder with built-in auxiliary discharging structure". In this device, a chassis is provided on both sides of the shredder table, and a motor is installed inside the chassis. A connecting rod is installed at the output end of the motor, and a toothed roller is provided at the end of the connecting rod; a tearing tooth is fixedly installed on the surface of the toothed roller, and a section of the tearing tooth is connected with teeth; a feeding box is fixedly installed in the middle above the shredder table. Compared with the existing device, the plastic shredder with built-in auxiliary discharging structure is convenient to accelerate the crushing efficiency of plastic products by setting double motors, connecting rods and toothed rollers. The toothed rollers bite each other to make the plastic products more thoroughly crushed, thereby increasing the crushing speed and the output. The use of tearing teeth and teeth facilitates the degree of shredding of plastic products, so that the shredding is successful at one time, the crushing rate is increased, and the working process is accelerated.

[0004] Although the above device has certain advantages, it still has certain defects:

[0005] 1. The setting of the annular screen can make the plastic be torn into pieces until it is small enough to pass through the screening of the annular screen, but the plastic may also be blocked in the annular screen and cannot pass through, which also affects subsequent work.

[0006] 2. The plastic dropped from the feeding trough is shaken by the cooperation of the telescopic rod and the push block to help discharge the material. This can only assist the discharge of the shredded plastic, and cannot further help the discharge work of the annular screen, and the overall work efficiency cannot be improved.
