Leather surface coating device capable of automatically adjusting adding amount of coating liquid according to rotating speed

Abstract

The invention provides a leather surface coating device capable of automatically adjusting the adding amount of coating liquid according to the rotating speed, and belongs to the technical field of leather manufacturing surface coating devices. The leather surface coating device comprises a rotating shaft, wherein the rotating shaft is sleeved with a connecting sleeve, telescopic cylinders are evenly connected to the side face of an outer shaft of the connecting sleeve, the ends, away from the connecting sleeve, of the telescopic cylinders are fixedly connected with magnetic blocks, a fixing shaft is connected in an adding base, and a rotating plate is rotationally connected to the fixing shaft. According to the leather surface coating device capable of automatically adjusting the adding amount of the coating liquid according to the rotating speed, the rotating shaft is used for driving the magnetic blocks on the telescopic cylinders through the connecting sleeve, and the adding amount of the coating liquid is automatically adjusted according to the rotating speed of a roller through the combination effect of magnetic attraction balls, the rotating plate and an energy-saving groove; compared with an existing fixed-amount adding manner, the requirement of different rotating speed changes of the roller for the amount of the coating liquid can be met, the coating uniformity is correspondingly improved, and the coating effect and efficiency are correspondingly improved; and meanwhile, the beneficial effects of being simple in structure, convenient to use, capable of saving energy and environment-friendly are achieved.

Description

technical field [0001] The invention relates to the technical field of leather manufacturing surface coating devices, in particular to a leather surface coating device that automatically adjusts the amount of coating liquid added according to the rotation speed. Background technique [0002] There are many kinds of leather, which are widely loved by consumers because of their hygienic properties such as warmth retention, breathability, and sweat absorption and perspiration. Leather is generally denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. , can be used in the fields of clothing, furniture, and industry, and has a wide range of applications. As people's demand for use increases, in order to improve the performance of leather and make it meet people's needs, existing leather products are used in the production process. , a certain thickness of protective layer will be coated on the leather surface, w...

AI Technical Summary

Problems solved by technology

[0003] At present, when the leather coating machine coats the leather surface, it generally uses a roller to roll on the leather surface to evenly coat the coating liquid on the leather surface. The existing commonly used adding methods mainly include manual quantitative addition or automatic quantitative addition. When the rotation speed of the roller changes, the amount of coating liquid added cannot meet the speed of roller coating, thereby reducing the coating efficiency. Uniformity affects the coating effect. Secondly, some coating liquids are added through automatic variables, but its structure is too complicated, consumes a lot of energy, and is inconvenient to use.
