Description

Technical Field

[0002] The diffusion plate can be applied to many display and light-emitting fields such as backlight modules and lighting fixtures. In the production of the diffusion plate, the quantum dot material and the resin base material are usually blended and the quantum dot diffusion plate is produced by an extruder. Then, according to actual needs, the quantum dot diffusion plate is cut into plates of different sizes and specifications by cutting equipment to be suitable for display screens of different sizes (such as 32 inches, 55 inches, 65 inches, etc.). In the production of the diffusion plate, the cut waste of the diffusion plate can be crushed by a crusher for subsequent reuse.

[0003] The pulverizing device in the related art generally includes a support frame and a pulverizer. The cut waste is fed into the pulverizer from the bottom port, and then the pulverizer pulverizes the cut waste. Subsequently, the waste particles are discharged through the bottom port of the pulverizer.

[0004] However, after the shredder shreds the cut waste, some large pieces of waste may not be completely shredded. Workers need to manually sort the large pieces of waste or use a screening machine to screen the granular waste, which not only increases the burden on the workers but also affects production efficiency.
