Description

Sole polishing clamp manufacturing device and polishing clamp manufacturing and using method

Technical Field

The invention relates to the technical field of sole clamp devices, in particular to a clamp manufacturing device for sole polishing and polishing clamp manufacturing and using methods.

Background

With the continual improvement and upgrading of modern manufacturing plants, robots have begun to replace labor extensively in production operations. At first, the scene of replacing manual production by robots mostly appears in some production with heavy labor load and high hazard, and since market competition is increasingly intense, many labor-intensive enterprise factories also urgently need to improve and upgrade production modes, and robots are introduced to replace intensive manual production to reduce cost and improve core competitiveness.

The shoe industry is typically a labor-intensive industry, and in recent years, as labor costs have increased, shoe manufacturers have decreased their profit margins. Up to now, the export of products in countries and regions such as the United states, European Union, Japan, etc. from the shoe industry of our country has shown a significant downward trend. The reason for this is that the shoe manufacturing industry in China is large and not strong, the labor cost advantage is no longer, the technical trade barrier and the TPP trade agreement are not strong, so that the shoe industry in China faces more and more competitive pressure. In order to solve the historical problem, the shoe making and forming process equipment must be changed to automation and intelligence, so that the production efficiency is improved, the labor is reduced, the quality is improved, and the cost is reduced.

Traditional sole processing means of polishing is more primitive, and equipment is relatively laggard, processes and adopts artifical mode more, and the edging of sole is influenced by the people greatly, and not only inefficiency is difficult to guarantee the product quality moreover. In addition, dust pollution caused by sanding is serious, and causes considerable harm to the health of workers. Since the sole is generally a flexible material with low hardness, various types of soles have various shapes and sizes, and the falling behind of the jig system has become one of the bottlenecks that restrict shoe automation. If a corresponding positioning fixture is customized for each shape and size, the cost of the fixture is high, the time is consumed, and the effect is poor in actual production. At present, the flexibility of the clamp system in the domestic shoe making field is not very good with the manufacturing unit with high flexibility.
