Description

Technical Field

[0001] The utility model relates to the technical field of wool combing machinery, in particular to a device for replacing a leather rubbing plate of a wool combing machine. Background Art

[0002] A wool combing machine is a machine that turns loose fibers into strips in wool spinning production. Its main function is to comb the messy fibers into relatively straight single fibers, remove impurities, and mix fibers of different colors or qualities. The wool combing machine used for wool spinning is generally composed of two- or three-roller combing machines. The raw materials are fed by an automatic wool feeder; there is an automatic semi-finished product curtain between each roller combing machine, called a "bridge machine"; the wool net output from the last roller combing machine is divided into narrow strips and twisted into coarse yarn for spinning by spinning machines. The wool combing machine used for worsted wool spinning is generally composed of two roller combing machines directly connected without a bridge machine. The output wool net is gathered into wool strips for the subsequent production of combed wool strips.

[0003] The rubbing board in the wool combing machine is a key component in the strip forming mechanism. The wool strips are formed by the rubbing and twisting action of the upper and lower rubbing boards. Generally, the surface grooves of the rubbing board are worn out after about three months of use. In addition, the rubber surface is affected by ozone in the air, which accelerates the aging of the surface. At this time, the surface of the rubbing board is smooth and the rubbing and twisting of the wool strips can no longer be completed. It must be replaced or repaired. The repair is difficult and needs to be continued within a short period of time after the repair. It cannot solve the fundamental problem. The best way is to replace it directly. The general replacement method is to manually remove the rubbing board from the wool combing machine. The internal disassembly and replacement space of the wool combing machine is small. Manual direct disassembly and replacement is time-consuming and labor-intensive, and the disassembly efficiency is low. In addition, manual disassembly is very prone to safety accidents.
