High-coating-rate reconstituted tobacco coating machine

Abstract

The invention discloses a high-coating-rate reconstituted tobacco coating machine which comprises a material receiving trough (1), a movable roller scraper (2), a coating roller pressurization device (3), a movable coating roller (4), a paper guide roller (5), a coating liquid groove (6), an end face sealing device (7), a fixed coating roller (8), a fixed roller scraper (9), a stander (10) and a roller clearance adjustment device (11), wherein the movable coating roller (4) and the fixed coating roller (8) are mounted on the stander (10); the coating liquid groove (6) is arranged above a space between the movable coating roller and the fixed coating roller; sealing strips (6b) on two sides of the coating liquid groove (6) are in contact with the roller surfaces of the movable coating roller and the fixed coating roller to seal the movable coating roller and the fixed coating roller. By the adoption of a mode of coating a sheet base by combining immersion coating of the coating liquid groove with coating of the coating rollers, the high-coating-rate reconstituted tobacco coating machine can realize both high-coating-rate coating work and high-speed running, so that the production efficiency is greatly improved. The high-coating-rate reconstituted tobacco coating machine is simple in structure and easy to manufacture.

Description

technical field [0001] The invention belongs to the structural technical field of reconstituted tobacco leaf coater by papermaking method. Background technique [0002] In the current papermaking reconstituted tobacco leaf production technology, roll coating is mostly used for base coating, and dip coating is also used in some cases. Due to the shallow coating liquid level and low coating rate of roll coating, the quality of reconstituted tobacco leaf products obtained is poor, and the molding quality is poor. ; The disadvantages of the dip coating method are that the mesh belt is difficult to clean, the loss of the coating liquid is large, and the operating speed is low. Contents of the invention [0003] The object of the present invention is to provide a high coating rate coating machine for reconstituted tobacco leaves which has a high base coating rate and can run at a high speed, aiming at the shortcomings of the above-mentioned prior art. [0004] The purpose of t...
