Paper tube crushing machine

Abstract

The invention relates to a paper tube crushing machine. The paper tube crushing machine comprises a rack and a feeding unit, a crushing box and a discharging system which are sequentially arranged onthe rack in the conveying direction of paper tubes; a crushing tool is arranged in the crushing box, and a driving motor of the crushing tool is arranged on the rack; and the crushing tool comprises apower shaft arranged on the crushing box by means of an installing plate, limiting plates arranged on the power shaft at intervals, a group of pin shafts which are arranged on the exterior of the power shaft and penetrate through the limiting plates and crushing hammers, the crushing hammers and the pin shafts are connected and arranged between the installing plate and the limiting plates and between the adjacent limiting plates correspondingly, the crushing hammers have the rotating freedom degree on the pin shafts, and the bottom of the crushing box is provided with a grid in the mode of being matched with the crushing hammers. According to the crushing machine, the manufacturing difficulty of the crushing tool can be effectively reduced, the service life is prolonged, the crushing timeis shortened, and the good crushing effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of paper shredding equipment, in particular to a paper tube shredder. Background technique [0002] In the prior art, for crushing paper, especially paper tubes, such as fireworks barrels, paper tube shafts during coil processing, etc., a rotating blade is usually used as a crushing tool. However, the structure of the rotating blade is used for crushing, and there are the following problems: 1. Due to the toughness and strength of the paper tube, the paper tube is not easy to break, and the strength of the rotating blade is high, which requires special processing. After the blade is worn, the output decreases significantly. The replacement cycle of the paper tube is short and the replacement is frequent, resulting in an increase in cost; 2. In order to ensure the crushing of the paper tube, it is necessary to crush the paper tube many times and for a long time (manual forced feeding is required), resulting i...
