Dry production line for PU synthetic leather

Abstract

The invention discloses a dry production line for PU synthetic leather. The dry production line comprises a dip dyeing box, wherein a drying box is fixedly connected to the right side of the dip dyeing box, pulleys are movably connected to two sides of an inner cavity of the dip dyeing box through rotating shafts, a box body is fixedly connected to the bottom of the inner cavity of the dip dyeingbox, and a groove body is formed in the top of the box body. Through cooperative use of the dip dyeing box, the drying box, the pulleys, the box body, the groove body, an air cylinder, a roller, an outer shell, a fixing rod, a first motor, fan blades, a mounting frame, a heater, a base, an operation table, a shell, a second motor, a threaded rod, a threaded sleeve, a connecting rod and a cutting machine, the problem that in a traditional leather swabbing process, swabbing operation is independently conducted, and orderly drying and cutting cannot be achieved is solved. According to the dry production line, manual operation can be effectively reduced, orderly dip dyeing and swabbing, drying and cutting are achieved, the labor burden is reduced, meanwhile, the working efficiency is improved,and the dry production line for the PU synthetic leather is simple in structure.

Description

technical field [0001] The invention relates to the technical field of PU synthetic leather, in particular to a dry-process production line of PU synthetic leather. Background technique [0002] PU synthetic leather is also called polyurethane synthetic leather. Its back is base fabric, which is easy to melt when burned. It has many advantages that PVC synthetic leather cannot match. It is an ideal material to replace natural leather. The production method of PU synthetic leather can be divided into dry and dry. There are three kinds of method, wet method and agglomeration Xufu method. The dry method refers to making PU resin into a sol with a certain solid content and a certain viscosity, coating it on the release paper as a carrier, and controlling a certain temperature and speed through an oven. Wait for the process conditions to make the solvent volatilize to form a film, and then coat the adhesive layer on it and then compound it with the base cloth. After drying, curin...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a PU synthetic leather dry-process production line, which has the advantages of drying and cutting, and solves the problem that the pulping operation is performed separately. After the pulping is completed, it needs to be manually transported to the drying equipment for drying, which is not only time-consuming It is laborious, increases the labor intensity of workers, and the production efficiency is low. Moreover, during the leather transportation process, the leather sizing solution is not completely dry, and the leather is stacked on each other, which affects the quality of the leather.
