Auxiliary tool changing device of drum type chipper

Abstract

The present invention relates to a drum chipper, and particularly relates to an auxiliary cutter changing device of drum chipper. The auxiliary cutter changing device of drum chipper comprises an inserted pin (9), a positioning block (10) and a chipper base hole (8-1). The positioning block (10) is installed on a lining board (12) at the end plane of cutter roller (11). A positioning hole (10-1) is provided on the positioning block (10). The chipper base hole (8-1) is installed on a chipper base side plate (8). The auxiliary cutter changing device of drum chipper also comprises an auxiliary cutter changing motor (1), a coupling (2), a speed reducer (3) and an electromagnetic clutch (4). The auxiliary cutter changing motor (1) is connected with an input shaft (3-1) of speed reducer (3) through the coupling (2). The electromagnetic clutch (4) is installed between the output shaft (3-2) of speed reducer (3) and a main shaft (6) of drum chipper driving device (5). The auxiliary cutter changing device of drum chipper according to the invention has the advantages of: (1) time saving, labor saving, and short changing time; (2) greatly increased production efficiency.

Description

technical field [0001] The invention relates to a drum chipper, in particular to an auxiliary tool changing device for a drum chipper. Background technique [0002] The drum chipper is based on wood harvesting residues (such as small-diameter wood, branches, etc.), wood processing residues (such as slabs, slats, round wood cores, waste veneers, etc.) and non-wood raw materials (such as bamboo, wood, etc.) Straw, wheat straw, cotton stalks, etc.) are used as cutting raw materials, and the raw materials are cut and processed into certain specifications of wood or non-wood chips. The drum chipper can be used as a material preparation machine for MDF, particle board, papermaking and other industries. It can also be used as a direct production equipment for finished wood chips. When the drum chipper is working, the working motor in the driving device of the drum chipper starts, and through the belt drive, the shaft fixed to the large pulley rotates, so that the knife roller fixe...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of the cutter roller, for example, the weight of the cutter roller of a large-scale drum chipper reaches about 8.5 tons. When replacing the flying knife, several adults are needed to complete the rotation of the cutter roller. The current drum chipper assists the tool change The device has the following defects: (1), time-consuming and labor-intensive, the replacement time is long, and it takes a long time to replace the flying knives because it takes a long time to rotate the knife rollers, so it generally takes about an hour to replace all the flying knives on the drum chipper time, and the labor intensity of workers is high, which consumes a lot of manpower, resulting in a waste of human resources; (2), greatly reducing production efficiency

It is necessary to stop the operation when replacing the flying knife, and the production cannot be carried out. Due to the long time for changing the flying knife, this greatly reduces the production efficiency
