Upper grabbing line tensioning device

Abstract

The invention provides an upper grabbing line tensioning device, and belongs to the technical field of shoes.The upper grabbing line tensioning device solves the problem that an existing upper bind-off and line pulling device is large in occupied space.The upper grabbing line tensioning device comprises a machine frame and a fixed base.A traction structure used for pulling an upper grabbing line is arranged on the machine frame and comprises a traction piece and a line guide wheel.The line guide wheel is located between the traction piece and the fixed base.The traction piece is a cylinder or an oil cylinder or a winch.The cylinder or the oil cylinder is vertically arranged.A cylinder body of the cylinder or the oil cylinder is fixedly connected with the machine frame.The winch comprises a winch body which is fixedly connected with the machine frame.A fixing structure used for fixing a shoe tree is arranged on the fixed base.By means of the structure of the upper grabbing line tensioning device, the occupied area of the upper grabbing line tensioning device can be remarkably narrowed, and the upper grabbing line tensioning device has the advantages of being reasonable in structure arrangement, compact in structure, convenient to transport and low in manufacturing cost.

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.
