Abstract

The invention discloses a vacuum embossing machine for PU synthetic leather, which aims to solve the problem that the embossing operation of PU synthetic leather is not good and the product quality is reduced by extrusion. The invention comprises a frame, a roller mounted on the frame by rotation, a ventilating pattern cylinder is arranged outside the roller, a suction cylinder is installed between the roller and the ventilating pattern cylinder, and a number of axial devices are evenly arranged in the suction cylinder. The outer wall of the suction tube is equipped with a row of suction holes corresponding to each air hole. The shaft core is connected with the rotary joint for air on the rotating mandrel for air, and the rotary joint for water is connected with the rotating mandrel for water. One end of the channel hole is connected with a vacuum flow control mechanism, and the vacuum flow control mechanism is connected with the rotating shaft core for gas.

Description

technical field [0001] The invention relates to a synthetic leather processing technology, more particularly, to a vacuum grain suction machine for PU synthetic leather. Background technique [0002] The existing synthetic leather adopts an embossing process in the production process, and uses embossing equipment to extrude production materials such as PU, and forms texture patterns on the production materials through steel wheels, nickel wheels, and silicone wheels on the equipment. This embossing process requires a pressure of 3kg per square centimeter of the production material, which is likely to reduce the thickness of the synthetic leather material and make the hand feel stiff. The subsequent kneading process must be used for treatment, which will increase the production cost, and the kneading with chemical additives will generate a large amount of industrial waste water. To sum up, the embossing operation of PU and other production materials by means of extrusion has...
