Thermal sensitive paper producing and processing machine and thermal sensitive paper producing and processing technology

Abstract

The thermo-sensitive paper production and processing machine comprises a first fixing frame, a second fixing frame, an unwinding drum, a winding drum and a coating device, the first fixing frame and the second fixing frame are symmetrically installed on the existing ground front and back, the first fixing frame is located on the left side of the second fixing frame, and the second fixing frame is located on the right side of the second fixing frame. An unwinding drum is rotatably connected between the two first fixing frames, a winding drum is rotatably connected between the two second fixing frames, and a coating device is arranged between the unwinding drum and the winding drum. The conditions that too much coating is discharged at a time, so that the coating is wasted, and the coating effect is poor can be avoided, and the function that the coating is evenly distributed on the surface of the thermo-sensitive paper can be achieved through the scraping unit in the coating device.

Description

technical field [0001] The invention relates to the technical field of heat-sensitive paper, in particular to a heat-sensitive paper production and processing machine and a production and processing process. Background technique [0002] Thermal paper is also known as thermal fax paper, thermal recording paper, and thermal copy paper. The principle of thermal paper is to coat ordinary paper with particle powder, and the composition is colorless dye phenol or other acidic substances. , separated by a film, under the condition of heat, the film melts, and the powder mixes to develop a color reaction. The colored writing on the thermal paper is unstable and easy to fade, making the content of the document difficult to read. [0003] The quality of thermal paper directly affects the printing quality and storage time, and even affects the service life of printers and fax machines. Thermal printing paper is generally divided into three layers, the bottom layer is paper base, and t...

Problems solved by technology

[0004] 1. The existing heat-sensitive paper production and processing machinery cannot control the discharge of paint during the coating process, and it is prone to excessive discharge of paint that leads to waste of paint, and in the process of heat-sensitive paper transmission , thermal paper is prone to looseness, resulting in uneven coating distribution and difficult winding;

[0005] 2. During the coating process of the existing heat-sensitive paper production and processing machinery, the coating is prone to uneven thickness and uneven distribution of the coating. At the same time, the coating adhered to the mechanical parts is not timely If it is removed, it is easy to affect the subsequent coating effect
