A tightening and flanging mechanism and a tightening and flanging method of a shoe upper grasping machine

Abstract

The invention provides a tightening and flanging mechanism and a tightening and flanging method of a shoe upper grasping machine, which belong to the field of mechanical technology. The utility model solves the problems of low efficiency and low yield of the existing shoe upper grasping machine for tightening and flanging. The tightening and flanging mechanism of the shoe upper grasping machine is characterized in that it includes a tightening block, a finger pushing block, a finger pressing plate and an edge wrapping strip, the finger pressing plate is arranged above the finger pushing block, and the edge wrapping strip The upper end is covered on the front end of the finger-pressing board, the lower end is covered on the front-end of the finger-pressing board, and the finger pushing block is slidably connected with the tightening block. It presses the upper to the shoe last through the tightening block, and fixes the position of the shoe last. When working, the edging strip is pressed against the upper under the action of the finger pushing block and the finger pressing plate, and moves along with the finger pushing block and the finger pressing plate. The linkage realizes the lasting, stretching and flanging of the upper, and pressurizes and bonds the upper and the midsole of the shoe together. It is simple in structure, easy to operate, better in tightening, lasting and bonding, and will not squeeze the midsole during the lasting process.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a leather product machinery, in particular to a tightening and flanging mechanism and a tightening and flanging method of a shoe upper grasping machine. Background technique [0002] Shoes are indispensable daily necessities in daily life, and the production of shoes must go through many complicated processes before reaching the finished product. In the shoe production process, shoe upper grabbing is one of the essential processes in the shoemaking operation. Using the shoe upper grabbing machine can easily realize the mechanized production of the shoe upper grabbing process. [0003] When the existing upper grabbing machine grabs the upper, the upper cover is pressed on the shoe last, and the upper is pressed and glued. In the upper grabbing process, the upper needs to be tightened and stretched to remove or reduce wrinkles. , in order to achieve the purpose of sticking the las...

Problems solved by technology

In this field, the stretching treatment of the middle side can be roughly divided into manual stretching and mechanical stretching directly manipulated by personnel. The quality of manual stretching and the speed of stretching depend entirely on the skills and experience of the operator. The efficiency is relatively low, and the mechanical stretching can improve the work efficiency to a certain extent due to the high requirements of the program control, but because the stretching process cannot be automatically adjusted, the position of the upper cover on the shoe tree will be different. When the offset is not in place, the stretching effect is not ideal, and it is easy to cause damage to the upper during the stretching process

While grasping the upper, it is also necessary to pressurize and bond the upper and the midsole, and use hydraulic transmission as a power transmission, so that the edge block can be pressed on the side of the shoe, and the finger push block can be pressed on the midsole of the shoe. , so as to make the upper closely adhere to the last and firmly stick to the midsole. However, when this type of finger push block exerts pressure on the upper, it is easy to squeeze and deform the midsole of the shoe. If it does not directly press the upper The foot exerts pressure, and it is easy to cause the shoe upper and the shoe tree to not fit well enough, which cannot meet the requirements of the shoemaking process
