Upper grip line tensioning device

Abstract

The invention provides a shoe upper catching line tension device, and belongs to the technical field of shoes, which solves the problem of poor universality in the existing shoe upper closing line tension device. The shoe upper catching line tension device comprises a machine frame and a fixing base, wherein a traction structure for pulling an upper catching line is arranged on the machine frame; the fixing base is positioned at the back side of the traction structure; a fixing structure for fixing a shoe tree is arranged on the fixing base; the fixing base and the machine frame are mutually connected by an angle adjusting structure, and the angle adjusting structure is used for swinging the fixing base back and forth and locking the fixing base onto the machine frame. The shoe upper catching line tension device has the advantages that by adjusting the inclining angle of the fixing base, the shoe upper catching line tension device is suitable for tensioning upper catching lines of different models of shoe uppers, so that the universality is high; by adjusting the inclining angle of the fixing base, the upper catching quality, upper catching efficiency and upper catching qualified rate are improved.

Description

technical field [0001] The invention belongs to the technical field of footwear, and relates to a shoe-making device, in particular to a shoe upper grasping thread tensioning device. Background technique [0002] Shoes are indispensable items in people's daily life, and in the process of making shoes, upper catching of shoes is one of the important manufacturing processes. When the upper grabs the upper, the upper cover is pressed against the last. In the process of grabbing the upper of the shoe, it is necessary to tighten and stretch the upper of the shoe, remove or reduce wrinkles, so as to achieve the purpose of sticking to the last, thereby improving the aesthetic feeling of the shoe. [0003] The existing shoe upper grasping process mainly adopts manual operation, and the quality of the manual operation depends entirely on the technology and experience of the operators, which has the problems of low efficiency of grasping the upper, difficult quality control, and high...

AI Technical Summary

Problems solved by technology

[0003] The existing shoe upper grasping process mainly adopts manual operation, and the quality of manual operation depends entirely on the skills and experience of the operators. There are problems such as low grasping efficiency, difficult quality control, and high labor intensity for workers.

[0004] For this reason, someone has proposed a shoe upper closing cable device (CN203748776U), which adopts mechanical traction to grab the upper line, realizes improving tension efficiency and reducing labor intensity of workers; but this shoe upper closing cable device still has some deficiencies: 1 1. The shoe upper closing cable device has the problem of taking up a lot of space; 2. The shoe last is fixed on the frame and cannot be adjusted, and the size and height of the shoe last are different for different shoe sizes and styles, so the shoe upper closing cable device has poor versatility

3. When the upper is grasped, the upper is only put on the shoe last. When the upper is tightened, it is easy to cause the last to shift or even fall off.
