Polishing device of leather polisher for shoemaking

Abstract

The invention discloses a polishing device of a leather polisher for shoemaking. The polishing device comprises a left beam (1), wherein a transverse beam (2) is connected with the middle of the left beam (1), the transverse beam (2) is connected with a right beam (3), two ends of both the left beam (1) and the right beam (3) are connected with rollers (4) which are connected with each other through a belt (5), the transverse beam (2) is provided with a hydraulic device (6), the extending end of the hydraulic device (6) is connected with a compressing plate (7), a pressure piece (8) which is arranged at the bottom surface of the compressing plate (7) is connected with a controller (9), the controller (9) is connected with the hydraulic device (6), an infrared sensor (10) arranged at the front end of the left beam (1) is connected with the hydraulic device (6), and the outside surface of the belt (5) is of a transverse sand grain structure.

Description

technical field [0001] The invention relates to a grinding device, in particular to a grinding device of a leather grinding machine for shoemaking. Background technique [0002] During the production process of leather shoes, the sole and the upper need to be glued together. Since the surface of the untreated leather is relatively smooth, it is not easy to stick to each other after the leather is applied with glue, and it is easy to cause the shoes to be glued. Therefore, before gluing, it is necessary to Grind the leather that needs to be bonded to make the surface rough and increase the viscoseness of the glue in the combined part. At present, sandpaper is generally used for manual grinding, or a manual grinding machine is used to grind the leather materials to be polished one by one. These grinding methods are not only slow in grinding speed and low in work efficiency, but also have high labor intensity for workers. It is beneficial to large-scale production; at the same...

AI Technical Summary

Problems solved by technology

At present, sandpaper is generally used for manual grinding, or a manual grinding machine is used to grind the leather materials to be polished one by one. These grinding methods are not only slow in grinding speed and low in work efficiency, but also have high labor intensity for workers. It is conducive to large-scale production; at the same time, it is difficult for workers to maintain a good working condition when polishing by hand, and each person's working ability is different, so the quality of the products produced cannot be well guaranteed

Therefore, the existing technology has problems such as slow grinding speed, low efficiency, high labor intensity, unfavorable for large-scale production and difficulty in ensuring the quality of grinding.
