Flow-line pneumatic leather hot-pressing bonder and production technique thereof

Abstract

The invention discloses a flow-line pneumatic leather hot-pressing bonder which comprises an electromechanical part and a control part, wherein the electromechanical part comprises an upper frame and a lower frame; in the upper frame, the tail ends of two cylinder piston rods are fixedly provided with a pressure plate, and a heating unit is installed on the pressure plate; the lower frame is provided with a conveyer belt; and the conveyer belt is connected with a transmission-containing motor installed on the lower frame through a chain. The invention also discloses a production technique of the bonder, which comprises an operating method, heating temperature, press-fit pressure, press-fit heating time and the like. When the bonder and production technique thereof are used for producing the press-fit leather and lapping cloth, the leather and lapping cloth can be bonded very firmly, and can not be separated easily; and the leather and the heat-shrinkable material can not generate buckling deformation; and the qualification rate of the product is enhanced to 90-100%.

Description

technical field [0001] The invention relates to the technical field of leather bonding. Background technique [0002] Traditional leather pressing modes include: manual pressing and roller pressing. The first method has low efficiency, 600 pieces per hour, and the pressing effect is poor. The second method is efficient, but the pressing effect is not good, and the pressed leather is easy to separate from the interlining. And because the upper and lower rollers are heated, the leather should not be heated and then cooled, and the thermal expansion and contraction coefficients of the leather and the interlining are different, especially for materials that shrink when heated, resulting in warping of the processed leather or the aforementioned materials. This deformation is irreversible, so it directly leads to waste products. The pass rate is only 80-90%. Contents of the invention [0003] The present invention aims to provide an assembly line type pneumatic leather therm...

Problems solved by technology

The first method is inefficient, 600 pieces per hour, and the pressing effect is poor

The second method is efficient, but the pressing effect is not good, and the pressed leather is easy to separate from the interlining

And because the upper and lower rollers are heated, the leather should not be heated and then cooled, and the coefficients of thermal expansion and contraction of leather and interlining are different, especially materials that shrink when heated, causing warping and deformation of the processed leather or the aforementioned materials.

This deformation is irreversible and therefore directly results in waste

Pass rate is only 80-90%
