A shoe upper fixing device for shoe production

Abstract

The invention discloses a shoe upper fixing device used for shoe production, and relates to the technical field of shoe production. The invention comprises a base, a surface of the base is fixedly connected with a plurality of guide rail pillars, and the sides of several guide rail pillars are slidably connected with lifting platforms, a surface of the lifting platform is fixedly connected with a plurality of telescopic devices, and one end of several guide rail pillars is fixedly connected with a limiting plate, the base One surface is fixedly connected with a rotating shaft, and the other surface of the rotating shaft is connected with a screw for rotation. One end of the screw runs through the lifting platform and extends to the top of the lifting platform. The end of the screw at the top of the lifting platform is covered with a shoe last. Cooperate with each other, so that the arc-shaped pieces of the front fixing device and the rear fixing device protrude out of the shoe last to fix the inner surface of the shoe upper, and the shoe last with adjustable size can avoid the use of shoe lasts of different specifications, saving production resources and reducing the production cost of the factory. It has the advantage of improving the economic benefits of shoe production.

Description

technical field [0001] The invention relates to the technical field of shoe production, in particular to a shoe upper fixing device for shoe production. Background technique [0002] All parts on the sole, sewn or otherwise combined into an integral unit, combined with the inner and outer soles are called uppers. The upper is the basic part of a pair of shoes, consisting of the front part or the front part of the shoe, the back part is the side and rear part of the shoe, and the shoe lining for strengthening the upper. Help surface can use various materials, can be natural leather, man-made synthetic material or fabric etc. Because of the pores on the leather, the leather has good air permeability, so that the feet can be kept cool, so the leather upper has obvious advantages in the choice of upper material. The plasticity of the animal skin further adapts to the shape of the foot, allowing the foot to breathe and help the foot function. On the contrary, when the upper su...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a shoe upper fixing device for shoe production. Through the mutual cooperation of the extruding block and the screw rod, the arc-shaped pieces of the front fixing device and the rear fixing device protrude from the shoe last to hold the shoe upper The inner surface is fixed, and the size-adjustable shoe last can avoid the use of shoe lasts of different specifications, which saves production resources, reduces the production cost of the factory, and solves the problem of waste of production resources; through the arrangement structure of 300 telescopic devices, it can When the shoe upper is put on the shoe last, it fits the shoe upper very well, and with the adjustment function of the shoe last, the inside and outside of the shoe upper are squeezed, can be unfolded and fixed well, and there will be no wrinkles and shaking, which solves the problem of the shoe last The problem of wrinkles and shaking is easy to occur; through the mutual cooperation of the rotating rod and the screw, the upper can be fixed conveniently and quickly, with a single structure and simple operation process, which solves the cumbersome problem of the existing upper fixing process
