Automatic protection device for rotating shaft stall during grinding of bamboo toy

Abstract

The invention relates to the technical field of bamboo toys, and discloses an automatic protection device for rotating shaft stall during grinding of a bamboo toy. The automatic protection device comprises a shell I, wherein the exterior of the shell I is fixedly connected to a motor, and the exterior of the motor is fixedly connected to a rotating rod I. Under the interaction of the shell I, the motor, the rotating rod I, a fixed shell, a fluid shell, movable blocks, telescopic springs, electrorheological fluid, wires, conductors, a shell II, a fixed ring, a coil and protruding blocks, when a rotating shaft stalls during grinding, the device can automatically conduct protection, in this way, the quality of a ground toy can be prevented from being damaged, the cost of an enterprise for manufacturing the bamboo toys can be reduced, the problem that the internal temperature of a grinding machine rises sharply due to stall can be avoided, the grinding machine can be prevented from being heated and damaged, meanwhile, fire disasters can be avoided, and the life and property safety of people can be protected.

Description

technical field [0001] The invention relates to the technical field of bamboo and wooden toys, in particular to an automatic protection device for the stall of the rotating shaft when the bamboo and wooden toys are polished. Background technique [0002] With the development of society, there are more and more bamboo and wooden toys on the market, but there are still many problems in the processing and polishing of bamboo and wooden toys. For example, the existing bamboo and wooden toy grinding machines do not have the function of stall protection. When the grinding shaft stalls, the quality of the polished toy may be damaged, so that people need to remanufacture the toy, which will cause a waste of material resources and increase the cost of manufacturing. The internal temperature will rise sharply, which may cause damage to the internal parts of the grinding machine. In severe cases, it may cause a fire, which will threaten people's lives and property safety. Moreover, the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic protection device for the stall of the rotating shaft when the bamboo and wooden toys are polished, which has the advantages of automatically protecting and polishing the rotating shaft when the grinding shaft stalls, and solves the problem of existing bamboo and wooden toys. The wooden toy grinding machine does not have the function of stall protection. When the grinding shaft stalls, the quality of the polished toy may be damaged, so that people need to remanufacture the toy, which will cause a waste of material resources, and furthermore Increase the cost of manufacturing, and at the same time, when the rotating shaft stalls, the temperature inside the grinding machine will rise sharply, which may cause damage to the internal parts of the grinding machine, and may cause a fire in severe cases, thereby threatening people's lives and property. Some grinding machines only grind by rotating the shaft, which will make the grinding effect poor, which will affect the quality of the polished toys
