Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a PBT granular material crushing device with good protection. Background Art

[0002] PBT pellets refer to plastic pellets made of polybutylene terephthalate (PBT). PBT is a thermoplastic polyester with good mechanical properties, thermal stability, electrical insulation and chemical stability. It is widely used in the electronics, electrical, automotive, machinery and other industries, especially in the manufacture of connectors, switches, buttons, cable insulation, automotive interior parts and electronic components and other precision components.

[0003] Publication No. CN211590917U discloses a plastic crushing and screening device, including a box, a screening net is provided inside the box, springs are fixedly installed at the four corners of the bottom of the screening net, and a mounting plate located directly below the screening net is fixedly installed inside the box. The plastic crushing and screening device is fixedly installed with a mounting plate at the bottom of the spring. When actually used, the crushed plastic is put into the feed port and the external motor is turned on to drive the transmission shaft to rotate, thereby driving the rotation of the crushing knife to crush the plastic. The particles generated by the crushing are screened and fall through the screening net. When the screening net is blocked by plastic particles, the weight of the screening net increases and the spring is compressed, thereby driving the screening net to move downward. At the same time, the column located at the top of the mounting plate just passes through the screening hole inside the screening net to remove the plastic particles blocked inside the screening net, thereby achieving the advantage of not being easy to block the screen. Although the plastic crushing and screening device can achieve the advantage of not being easy to block the screen, the protection of the feed during the crushing process is not ideal. If the operation is improper, it may cause material splashing or worker injury, which needs to be improved. Utility Model Content
