Feeding mechanism for leather imitation bottom sheet

Abstract

The invention discloses a feeding mechanism for a leather imitation bottom sheet. The feeding mechanism comprises a rack, a right conveying device, an overturning device and a left conveying device. Each of the right conveying device and the left conveying device comprises a conveying assembly, a transmission belt and a transmission motor. The overturning device comprises a conveying device, overturning supports, a support base, an overturning shaft, an overturning motor, a worm reducer and a transmission belt. The support base is arranged on the overturning shaft. The eight sets of overturning supports are fixed to the support base. Each set of overturning support includes eight pairs of square tubes, a certain included angle is formed between each pair of square tubes, and in other words, the upper row of square tubes and the lower row of square tubes are formed and used for conveying the leather imitation bottom sheet. The whole feeding mechanism is controlled through a PC controller. By means of the feeding mechanism, the leather imitation bottom sheet can be automatically overturned and automatically conveyed to a polishing or fine grinding device after the bottom face of the leather imitation bottom sheet is flatly ground, conveyance is stable during overturning, time and labor are saved, the work intensity is lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a feeding mechanism, in particular to a leather-like negative film feeding mechanism. Background technique [0002] Imitation leather bases are used as rubber and plastics to make soles, and are widely used in leather shoes and sandals. It can not only save rubber, but also give full play to the respective characteristics of rubber and plastics, so it develops rapidly. Existing production imitation leather negative film also needs its bottom surface to be ground with grinding machine after vulcanization process, and its surface is carried out surface coating printing process after polishing or fine grinding. However, the current polishing and fine grinding equipment can only grind the surface facing upwards of the imitation leather sheet. For the bottom surface of the imitation leather negative, the grinding surface is manually spliced, turned over and sent to another grinding machine for surface treatment. Polished or finely ...

However, the current polishing and fine grinding equipment can only grind the surface facing upwards of the imitation leather sheet. For the bottom surface of the imitation leather negative, the grinding surface is manually spliced, turned over and sent to another grinding machine for surface treatment. polished or finely ground before being conveyed to coated printing

However, the work efficiency of manual splicing and flipping is low, and the product size of the imitation leather film reaches 1100mm×1000mm. Manual splicing and flipping are labor-intensive, which also brings artificial scratches to the product surface and reduces the authenticity of the product. Rate

The patent application with the patent number 201510520046.0 discloses a plate turning equipment, including a frame, a left conveying mechanism, a right conveying mechanism, and a turning mechanism. The distance between the turning mechanism supports is too large to be effectively fixed. scratches, scratches, and automatic control cannot be realized; and its conveying mechanism is a roller method, because the imitation leather film is relatively thin, the thinnest is only 2.3mm, after the front is frosted, it will heat up and become soft, and the end of the film will hang when it is lifted horizontally. Falling or getting stuck between the conveying rollers, for imitation leather negatives with relatively low hardness, it will fall from the gap between the rollers, causing work to stop and affecting work efficiency
