Preheating box for leather embossing machine

Abstract

The invention discloses a preheating box for a leather embossing machine. The preheating box comprises a frame, a heating cover and a cloth guide roller, wherein a conveying belt group of which the two ends are distributed symmetrically and are used for fixing the two side edges of a piece of leather is arranged at the upper end of the frame; the heating cover covers the upper end face of the frame, and the bottom end of the heating cover is rotationally arranged on one side of the frame; the two ends of the cloth guide roller are arranged inside the frame; the cloth guide roller is used for positioning the leather from a pre-baking frame to conveying belts; the inner wall of the heating cover is partitioned into a heating segment and a heat preservation segment; the densities of gold heating tubes distributed on the heating segment are greater than the densities of the gold heating tubes distributed on the heat preservation segment. The preheating box has the advantages and beneficial effects that a novel mechanical structure is adopted in the scheme, and the distribution state of the gold heating tubes is changed, so that the effects of heating, performing uniform heating and protecting the leather from being damaged are achieved at the same time.

Description

Technical field [0001] The invention relates to a leather embossing machine, in particular to a preheating box on the leather embossing machine. Background technique [0002] Embossing machine can be used to emboss a specific pattern on the surface of artificial leather, which is more widely used in various fields; the embossing machine heats the base blank of artificial leather uniformly, and then passes between the embossing roller and the driving roller. Rolling, and finally cooling. [0003] The existing equipment generally consists of unwinding, heating, embossing, laminating, rewinding and other devices. The heating device is only composed of infrared quartz heating tubes to preheat the leather surface, but the heating efficiency of the infrared quartz heating tube itself is not high. It is easy to cause inconsistent temperature, which affects the embossing quality of leather. [0004] The announcement number is CN201120688Y, and the publication date is September 24, 2008. Th...

Problems solved by technology

However, the work of the gold heating tube in this scheme needs to be detected by the infrared probe before it can be controlled to open, which means that the implementation of the scheme is more complicated. When the infrared probe is damaged, the gold heating tube will stop working, so there will still be the above-mentioned problem of temperature difference. , at the same time, the purpose of the gold heating tube in this scheme is to compensate the temperature difference on the leather surface and prevent the temperature difference from being too large. The short time in the process of the gold heating tube leads to the problem of insufficient heating effect, resulting in the problem of large temperature difference
