Sandblasting raising machine and sandblasting fluffing technology for upper of leather shoes

Abstract

The invention relates to a sandblasting fluffing technology for uppers of leather shoes. The specific steps comprise: (1) preparing, firstly, inserting shoe trees which are sleeved with uppers into clamping grooves of a shoe tree support; (2) starting, the support holding the shoe trees moving downward and entering a fluffing seal box; (3) performing sandblasting and fluffing, a spray gun in the fluffing seal box starting to sandblasting and fluffing, in fluffing, high-pressure gas being sprayed out while sand grains of a sand box are pulled out, the sand grains being sprayed out with the high-pressure gas to uniformly hit the periphery of the uppers which are exposed out of the fluffing seal box, the skin of the uppers falling off and fibers of leather being exposed caused by uninterrupted high-speed jet friction of the sand grains applied on the surfaces of the uppers; (4) completing fluffing, the uppers which complete fluffing processing moving upward with the shoe trees to return to initial positions, and taking off the shoe trees. The sandblasting raising machine is rational in structure, and has high-quality and is efficient, saves manual work, and is high in automation degree. The machine and the technology effectively improve processing efficiency and processing quality of products, and the products are reliable and durable.

Description

technical field [0001] The invention belongs to the field of shoe-making production equipment, in particular to a sandblasting and raising machine for uppers of leather shoes and a sandblasting and raising process. Background technique [0002] At present, the conventional shoe-making process requires fluffing on the bonding edge of the upper, and then it is bonded with the sole to form a whole shoe, and finally the product is produced. The fluffing process directly affects the bonding firmness of the upper and the sole. Quality plays a vital role. Existing shoe manufacturers still mainly rely on manual hand-held equipment for raising processing, the process automation is low, the technical requirements for manual labor are high, and the labor intensity is high. For mechanical automatic raising processing equipment, because the size of the raising is limited by the grinding wheel, only a narrow ring-shaped raising area can be raised on the outer edge of the upper, which is ...

Problems solved by technology

Existing shoe manufacturers still mainly rely on manual hand-held equipment for raising processing, the process automation is low, the technical requirements for manual labor are high, and the labor intensity is high.

For mechanical automatic raising processing equipment, because the size of the raising is limited by the grinding wheel, only a narrow ring-shaped raising area can be raised on the outer edge of the upper, which is suitable for injection sole shoemaking and cannot be used for cold bonding process, and in use Once the glue is opened at the fluffed position, there will be a hidden danger of the upper and the sole detaching
