Vacuum suction and discharge machine and method of use thereof

Abstract

The invention relates to a fabric drying device, in particular to a vacuum suction discharging machine and an application method thereof. The vacuum suction discharging machine comprises a machine frame, a driving motor and a vacuum pump; a positioning cylinder is arranged on the machine frame, a vacuum cylinder is connected to the outer side of the positioning cylinder through a vacuum connectingassembly, a sealing disc connected with the vacuum connecting assembly and one end of the vacuum cylinder is arranged at one end of the positioning cylinder, a vacuum positioning disc connected withthe vacuum connecting assembly is arranged at the other end of the positioning cylinder, the positioning cylinder is connected with the vacuum connecting assembly and the other end of the vacuum cylinder through a vacuum connecting disc, spindles are arranged on the axes of the two ends of the positioning cylinder, the spindle at one end penetrates through the sealing disc and is connected with the driving motor, the spindle at the other end penetrates through the vacuum positioning disc and is rotationally connected with the machine frame, and the vacuum pump is connected with the vacuum positioning disc through a flexible pipe. The vacuum suction discharging machine has the advantages that it can be effectively avoided that the thickness synthetic leather production materials such as PUis lost, the hand feeling and the production quality are guaranteed, and water of PU synthetic leather is conveniently discharged.

Description

technical field [0001] The invention relates to the fields of PU synthetic leather industry, textile industry and automobile interior decoration, in particular to a vacuum suction and discharge machine and its application method. Background technique [0002] The PU synthetic leather fabric needs to be dried during the production process. The existing drying method is to squeeze the PU synthetic leather fabric through two parallel rollers to squeeze out the moisture contained in the PU synthetic leather. However, this method of extruding the fabric is likely to cause the PU synthetic leather fabric to bear relatively large rigid pressure. After the PU synthetic leather fabric is subject to large and continuous rigid extrusion, it is difficult to restore the original thickness, which is easy to cause the PU synthetic leather fabric to lose its original thickness. The fabric loses thickness and feels stiff to the touch. Subsequent kneading process must be used for processing,...

However, this method of extruding the fabric is likely to cause the PU synthetic leather fabric to bear relatively large rigid pressure. After the PU synthetic leather fabric is subject to large and continuous rigid extrusion, it is difficult to restore the original thickness, which is easy to cause the PU synthetic leather fabric to lose its original thickness. Fabric loses thickness and feels stiff

Subsequent kneading process must be used for treatment, which will increase production costs, and kneading after adding chemical additives will generate a large amount of industrial wastewater
