The shell 75 is circular in cross section, and the upper end of the shell 75 is provided with a feed inlet 71, and the feed inlet 71 is connected to the lower end of the blanking hopper 6.

The feed inlet 71 of the housing 75 is also provided with a tapered section 751 at the opposite end. The purpose of tapered section 751 is to reduce the diameter of the end of housing 75, facilitating connection of the end to an injection molding machine; meanwhile, the conical section 751 is also beneficial to extruding the waste keycaps.

In order to further increase the crushing effect of the keycap, the outer surfaces of the crushing wheel I22, the crushing wheel II 23, the crushing wheel III 31 and the crushing wheel IV 32 are provided with crushing teeth 5. The crushing teeth 5 mainly have two functions, namely, the crushing capacity of the waste keycaps is improved, and the phenomenon that the waste keycaps slip with the passive crushing roller and the active crushing roller is avoided; and secondly, the mutually meshed passive crushing roller and the active crushing roller are also meshed through the crushing teeth 5 on the crushing wheel, so that the synchronous rotation of the second crushing wheel 23 and the third crushing wheel 31 is ensured, and the synchronous rotation of the first crushing wheel 22 and the fourth crushing wheel 32 is ensured.

In order to prevent the broken waste keycaps from adhering to the outer surfaces of the passive crushing roller and the active crushing roller, a brush 61 is preferably arranged on the upper edge of the blanking hopper 6, and the brush 61 is connected with the outer surfaces of the first crushing wheel 22, the second crushing wheel 23, the third crushing wheel 31 and the fourth crushing wheel 32.
