Novel extrusion roller pressure regulating device

Abstract

The invention is applicable to the technical field of chemical fiber production, and provides a novel squeeze roller pressure regulating device which comprises a roller press, a conveying mechanism, a pushing air cylinder, a first pressure roller, a second pressure roller, a second pressure roller, a pressure regulating device, a pressure regulating device and a pressure regulating device, and the first pressure roller and the second pressure roller are oppositely arranged, and a gap for cloth to penetrate through is reserved between the first pressure roller and the second pressure roller. The output end of the air source is fixedly connected with the first pressure roller, the air source is communicated with the propelling air cylinder, the pressure values of a first manual adjusting valve and a second manual adjusting valve need to be manually adjusted in advance, and compressed air output by the air source passes through a low-pressure path of the first manual adjusting valve during normal work and then flows into the second manual adjusting valve through a low-pressure path of the second manual adjusting valve. When the joint detecting device detects joint cloth, the pressure switching valve switches the air source channel to the second manual regulating valve, the air channel passes through the high-pressure path of the second manual regulating valve, and the pressure switching valve controls the propelling air cylinder to automatically increase the pressure between the first pressure roller and the second pressure roller, so that redundant glue is squeezed away.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber production, and in particular relates to a novel extrusion roller pressure regulating device. Background technique [0002] After the cord fabric is dipped, offset printing is formed on the sky roller about 6-7m behind the joint, resulting in the quality of the cord fabric not up to standard and becoming waste fabric. The reason is that when the cord fabric is dipped in glue, there are too many layers in the joint part, which leads to unclean extrusion during the second bath, and finally excess glue remains on the top roller to produce offset printing. Contents of the invention [0003] The present invention provides a novel squeeze roller pressure regulating device, aiming to solve the problems mentioned in the background art above. [0004] The present invention is achieved in this way. A novel squeeze roller pressure regulating device includes: a roller press, which has: a first press...
