Problems solved by technology

[0004] The present invention is mainly aimed at the existing synthetic leather production equipment adopting the embossing process, using steel wheels, nickel wheels, etc. to extrude PU and other synthetic leather materials to form embossing, which will easily cause the thickness of synthetic leather production materials to decrease, lose the original thickness, and feel. In order to solve problems such as deterioration and influence on production quality, provide a PU that can effectively prevent PU and other synthetic leather production materials from losing their own thickness, ensure the feel and production quality, facilitate timely cooling of PU synthetic leather, and avoid the rebound of PU materials.

Embodiment 1

[0027] Such as figure 1 As shown, a PU synthetic leather vacuum embossing machine includes a frame 1, a roller 2 is installed in the middle of the frame 1, one end of the roller 2 is coaxially fixed with a rotating mandrel 5 for air, and the other end is coaxially fixed There is a rotating mandrel 6 for water. The rotating mandrel 5 for gas, the roller 2 and the rotating mandrel 6 for water can rotate relative to the frame 1, and the motor 9 is used to drive the rotating mandrel 5 for gas to rotate through the gears 21 meshing with each other. The outer side of the roller 2 is covered with a leather sheath 23, the outer side of the leather sheath 23 is covered with a fixed assembly 4, and the outer side of the fixed assembly 4 is covered with a ventilating pattern cylinder 3, the ventilating pattern cylinder 3 is made of ceramics, and the surface is made into the A molded side of the desired synthetic leather texture. The length of the roller 2 is greater than the length of ...

Abstract

The invention relates to a synthetic leather production device and particularly relates to a vacuum tattoo machine. The vacuum tattoo machine comprises a rack, wherein a roller is arranged on the rack, an air-permeable mold line cylinder is arranged on the outer side of the roller, and a fixing component for fixing the air-permeable mold line cylinder is arranged between the roller and the air-permeable mold line cylinder; a rotating mandrel for gas is coaxially arranged at one end of the roller, and is driven by a motor, a rotating joint for gas is connected to the rotating mandrel for gas, a rotating mandrel for water is coaxially arranged at the other end of the roller, a rotating joint for water is connected to the rotating mandrel for water, a vacuum gas passage is arranged in the rotating mandrel for gas and the fixing component, the part, positioned in the fixing component, of the vacuum gas passage is in conduction with the outer surface of the fixing component, and a cooling water passage is arranged in the rotating mandrel for water and the fixing component. The vacuum tattoo machine disclosed by the invention can prevent PU (polyurethane) and other synthetic leather production materials from losing the thickness, avoiding resilience of the PU synthetic leather production material, and realizing other effects.

Description

technical field [0001] The invention relates to synthetic leather production equipment, in particular to a PU synthetic leather vacuum embossing machine. Background technique [0002] Existing synthetic leather adopts embossing process in the production process, and uses embossing equipment to extrude PU and other production materials, and forms texture patterns on the production materials through steel wheels, nickel wheels, silica gel wheels, etc. on the equipment. This embossing process needs to bear a pressure of 3kg per square centimeter of the production material, which will easily cause the thickness of the synthetic leather material to decrease and the hand feel to become stiff. Subsequent kneading process must be used for processing, which will increase production costs, and the kneading after adding chemical additives will produce a large amount of industrial wastewater. [0003] For example, the Chinese publication number is: CN102260757A, a kind of embossing mac...
