Leather mechanical roller coater

Abstract

The invention discloses a leather mechanical roller coater. The leather mechanical roller coater comprises a main machine, a leather feeding machine and a leather receiving machine, wherein the main machine comprises a rack, a roller changing frame, a rubber coating roller, a steel-made pressure roller, a pressure roller adjustment device, a scraper device, a leather beating roller device and a leather receiving roller device; the leather feeding machine comprises an upper conveyor belt, a lower conveyor belt, a flattening roller wheel device, a leather-feeding angle-pressing device as well as a hairbrush cleaning device. Since the flattening roller wheel device and the leather-feeding angle-pressing device are mounted in the leather-feeding machine, the smoothness of the surface of the leather is ensured; the leather beating roller device is mounted at the leather outlet side of the rubber coating roller and the leather receiving roller device is mounted at the leather outlet side of the steel-made pressure roller so as to ensure that the leather is smoothly transmitted onto the leather receiving machine and prevent the leather from being adsorbed onto the upper surface of the roller body due to too small thickness and further influencing the leather outlet; by virtue of the hairbrush cleaning device mounted at the lower part of the steel-made pressure roller, the roller wheel can be timely cleaned and thus the coating quality of the leather is ensured.

Description

technical field [0001] The invention relates to the field of roller coating equipment, in particular to a leather machinery roller coating machine. Background technique [0002] The finishing process in the current market is divided into brush coating, spray coating and roller coating. [0003] Due to the low efficiency, high labor cost, low utilization of chemical materials, and uneven brushing surface, the brushing process has a great impact on the quality level of the finished leather. Because manual brushing is easy to affect human health, it does not meet environmental protection requirements. [0004] The spraying process sprays the leather surface evenly, requires only a small amount of labor, and can be operated. The cost of labor is low, and it is suitable for automatic assembly line operation. However, the existing spraying machine is sprayed by a plurality of spray heads, and the places with skins and without skins will be sprayed during the spraying process, whi...

AI Technical Summary

Problems solved by technology

At present, the roller coating process is mainly based on the reverse coating process, and the reverse coating process is that the steel finishing roller and the rubber pressure roller rotate in the same direction. 0.7mm or less), soft skin cannot pass through

The smooth coating process can pass through thinner and soft leather, but it is easy to be adsorbed on the surface of the finishing roller or pressure roller when passing, making it difficult to control, and because the idler will leave chemical materials in the production process, it will When a piece of leather passes through, it will adhere to the bottom surface of the leather, which will also have a great impact on the quality of leather roller coating.

When the leather is conveyed, the leather on the conveyor belt is difficult to lay flat. When the leather is conveyed from the leather feeder to the main machine, the edge of the leather sent from the feeder will easily warp and roll up, which will bring inconvenience to the roller coating work.
