Full-automatic sole sandblast grinding machine and sandblast polishing technology

Abstract

The invention relates to a full-automatic sole sandblast grinding technology. The specific steps comprise: (1) putting the innersole of a to-be-processed shoe undersole downward on a sole positioning bushing plate of a platform; (2) locking, that is, locking a shoe undersole fixing support to fix the shoe undersole; (3) sandblasting and polishing, that is, in fluffing, high-pressure gas spraying out from the nozzle of a spray gun, a sand pipe extending in sand in a sand box, sand grains being pumped out along the sand pipe, and with spraying of the high-pressure gas, sprayed high-pressure sand grains and the surface of the shoe undersole highly rubbing to roughen the surface; (4) cleaning, that is, at set polishing time, a blanking plate shutting down the inlet of the sand pipe, the spray gun spraying clean high-pressure gas to blow and clean sand grains residual on the surface of the shoe undersole; (5) the shoe undersole which completes polishing returning to an initial position, opening the sole fixing support, and taking down the shoe undersole. The grinding machine is rational in structure, and is in high quality and efficient, saves manpower, saves energy and is environmentally friendly, and the machine is high in automation degree. Processing efficiency of products and processing quality are effectively improved, and products are reliable and durable.

Description

technical field [0001] The invention belongs to the field of shoe-making production equipment, in particular to a fully automatic shoe sole sandblasting and grinding machine and a sandblasting and grinding process. Background technique [0002] In the cold-bonded shoemaking process, outsole grinding is an important process, and the quality of the outsole grinding directly affects the effect of Zhang Jie. The traditional process for many years has been to manually use the grinding wheel to raise the hair, all relying on the operator's ability Eye observation and technique belong to a skilled trade. If the outsole of the shoe is polished carefully and in place, the adhesion will be good. Otherwise, the adhesion will be weak or the glue will be easily peeled off. Moreover, this process is dangerous. Once the quality of the grinding wheel is not good enough, the grinding wheel may disintegrate under high-speed rotation. Causing catastrophic trauma to nearby workers. Moreover, ...

AI Technical Summary

Problems solved by technology

If the outsole of the shoe is polished carefully and in place, the adhesion is good. Otherwise, it is easy to bond weakly or the glue will be peeled off. Moreover, this process is dangerous. Once the quality of the grinding wheel is not good enough, there is a risk of disintegration of the grinding wheel under high-speed rotation. Causing catastrophic trauma to nearby workers

Moreover, the efficiency of this artificial grinding process is low, the scrap rate is high, the dust pollution generated by grinding is serious, and there is a fire hazard
