Elastic extrusion-type tightening mechanism for special paper coater

Abstract

The invention discloses an elastic extrusion tensioning mechanism of a special paper coating machine. The upper ends of two guide rods are connected by a horizontal plate, and the horizontal plate is located on the upper side of the connecting rod. The middle part of the upper end of the connecting rod is A guide cylinder with an upward opening is provided, and a spring is provided at the bottom of the inner cavity of the guide cylinder. A threaded rod is inserted into the position corresponding to the upper end of the horizontal plate and the guide cylinder, and the lower end of the thread rod goes deep into the guide cylinder. The lower end of the threaded rod is against the spring. The process is: S1 installation, S2 debugging efforts, S3 experiment and S4 re-debugging. The motor drives the driving roller to rotate, and the linear speed of the driving roller is greater than the transmission speed of the special paper, so that there will be slippage between the special paper and the stretching and tensioning effect. By rotating the rotating rod, the spring below is squeezed. The extrusion force of the driven roller can be adjusted to prevent excessive friction. At the same time, the flannelette layer on the top protects the paper from damage and ensures the transmission quality of special paper.

Description

technical field [0001] The invention belongs to the technical field of special paper coating machine tensioning, and relates to special paper processing, in particular to an elastic extrusion type tensioning mechanism of a special paper coating machine. Background technique [0002] There are many kinds of special paper, which is a general term for various special-purpose papers or art papers, but now sellers refer to art papers such as embossed papers as special papers, mainly to simplify the confusion of nouns caused by the wide variety. Specialty paper is paper with special purpose and relatively small output. Special paper originated from the carbonless copying paper successfully developed by the National Cash Register Company of the United States in 1945. Specialty paper is to use different fibers to make paper with special functions, such as synthetic fiber, synthetic pulp or mixed wood pulp and other raw materials alone, with different materials for modification or p...

Problems solved by technology

Special paper needs to use a coating machine to coat and process it. However, there is tension in the paper transmission. Once it is too loose and arched, it will affect the coating quality. Therefore, there are coating machine tensioning devices on the market, such as bulletin The number is CN 206015427U, and it realizes tension by swinging, but swinging back and forth may cause the paper to arch
