Self-cleaned double-roller type crushing machine

Abstract

The invention discloses a self-cleaned double-roller type crushing machine which comprises a shell, wherein a feeding hopper is arranged at the upper end of the shell; a crushing chamber is arranged below the feeding hopper inside the shell; crushing rollers are arranged at intervals inside the crushing chamber; two side ends of the crushing rollers are opened; crushing teeth are arranged in an annular array manner on the outer surfaces of the crushing rollers; thimbles are arranged at intervals among adjacent crushing teeth; the thimbles moveably insert and extend into the crushing rollers; the tail ends of the thimbles are fixedly arranged on rubber sleeves; the rubber sleeves are fixedly arranged inside the crushing rollers; hole expanding devices are arranged inside the rubber sleeves;air inlet tubes are arranged below the crushing rollers on the shell; an air guide plate is arranged above the air inlet tubes inside the shell; a discharge hopper is arranged below the crushing chamber. The invention aims to provide the self-cleaned double-roller type crushing machine, residue twigs adhered to the crushing rollers can be separated from the crushing rollers, and thus the crushingquality is improved.

Description

technical field [0001] The invention belongs to the field of hemp and plastic manufacturing, in particular to a self-cleaning double-roller crusher. Background technique [0002] Wood-plastic panels (wood-plastic composite panels) are widely used in furniture, indoor and outdoor decoration, vehicle and ship decoration, etc. In order to further improve the performance of wood-plastic panels, a certain proportion of plant fibers such as ramie stalks and cotton stalks are added to the raw materials of wood-plastic panels to process them into hemp-plastic panels. Before processing, it is necessary to crush the ramie stalks for subsequent mixing and other processes. When the existing crusher crushes plants such as ramie stalks, the residual branches of the plants will stick to the crushing rollers, which is difficult to clean, and accumulation of multiple layers will cause Affects the broken effect. Contents of the invention [0003] The object of the present invention is to ...
