Description

Technical Field

[0001] The invention relates to the technical field of synthetic leather manufacturing equipment, in particular to a laminating machine and method for ultra-fiber synthetic leather. Background Art

[0002] Microfiber synthetic leather (also called microfiber leather or microfiber synthetic leather) is mainly made of polyurethane fiber fabric and leather composite fabric by hot pressing. The synthetic leather laminating machine is a common synthetic leather processing equipment, which is used to bond polyurethane fiber fabric and leather composite fabric together to form microfiber synthetic leather.

[0003] The existing laminating machine lacks a cleaning structure for the polyurethane fiber material and the leather composite material when in use. If there are dust impurities on the bonding surface of the polyurethane fiber material and the leather composite material, the subsequent bonding quality of the polyurethane fiber material and the leather composite material will be reduced;

[0004] Furthermore, when the polyurethane fiber material and the leather composite material are being bonded together, excess glue will seep out from the edges, which will cause the microfiber synthetic leather to need to be cleaned separately in the subsequent process, thus reducing the processing efficiency of the microfiber synthetic leather.

[0056] A method for using a microfiber synthetic leather laminating machine comprises the following steps:

[0057] Step 1: The polyurethane fiber fabric and the leather composite fabric to be laminated can be unrolled through two unwinding shafts. In this process, the polyurethane fiber fabric and the leather composite fabric can be flattened through the multiple flattening shafts 6, so that the polyurethane fiber fabric and the leather composite fabric can be flatter during the conveying process;

[0058] Step 2: The tightness of the polyurethane fiber material and the leather composite material during the conveying process can be adjusted through the tensioning component;

[0059] Step 3: During the conveying of the polyurethane fiber fabric and the leather composite fabric, the adhesive fabric wound on the first unwinding shaft 38 can be used to adhere and clean the adhesive surface of the polyurethane fiber material and the adhesive surface of the leather composite material. In this process, the conveying speed of the two adhesive fabrics is the same as the conveying speed of the polyurethane fiber fabric and the leather composite fabric. Since the adhesive surface of the adhesive fabric can be in contact with the adhesive surface of the polyurethane fiber fabric and the leather composite fabric respectively, as the polyurethane fiber fabric and the leather composite fabric are conveyed, the adhesive surface of the polyurethane fiber fabric and the leather composite fabric can be adhered and cleaned by the adhesive fabric, and the dust and impurities on the adhesive surface of the polyurethane fiber fabric and the leather composite fabric can be cleaned, which can improve the subsequent bonding quality of the polyurethane fiber material and the leather composite material, and further improve the lamination quality of the microfiber synthetic leather;

[0060] The first unwinding motor 36 is started to unwind the adhesive fabric wound on the first unwinding shaft 38, and the first winding motor 31 is started to make the first winding shaft 34 wind up the adhesive fabric after use;

[0061] Step 4: After the polyurethane fiber fabric and the leather composite fabric are cleaned, glue can be sprayed on the bonding surface of the polyurethane fiber material and the leather composite material through the glue discharge pipe 44, so that the designated glue discharge device is connected to the glue discharge pipe 44 (the glue discharge device includes a feed pump and a container, and the feed pump can pump the glue in the container into the inside of the glue discharge pipe 44), and then sprayed at multiple nozzles 45, and there is no mandatory regulation on the number of nozzles 45, so that the glue can be sprayed on the bonding surface of the polyurethane fiber fabric or the leather composite fabric;

[0062] Step 5: After the polyurethane fiber material and the leather composite material are sprayed, they can be guided by the first guide shaft 40 and the second guide shaft, and further pressed by the two pressing shafts 41;

[0063] Step 6: At this time, both sides of the polyurethane fiber fabric and the leather composite fabric are in contact with the inner wall of the fourth frame 39 and the glue-absorbing fabric. At this time, the glue-absorbing fabric can absorb excess glue, and the pressed polyurethane fiber fabric and the leather composite fabric will fit each other. In this process, excess glue between the polyurethane fiber fabric and the leather composite fabric will overflow at the cavity 43, and the overflowed glue will be absorbed onto the glue-absorbing fabric in the cavity 43. The second unwinding motor 46 is started, so that the second unwinding shaft 47 can unwind the glue-absorbing fabric, and the second winding motor 48 is started, so that the second winding shaft 49 can wind up the glue-absorbing fabric, so that the leaked glue is cleaned up conveniently, so that the ultra-fiber synthetic leather does not need to clean up the finalized glue separately after hot pressing, and the processing efficiency of the ultra-fiber synthetic leather can be improved;

[0064] Step 7: Finally, the pressed polyurethane fiber fabric and leather composite fabric can be hot-pressed and bonded by multiple hot-pressing rollers 42, wherein the hot-pressing rollers 42 are usually made of steel, may be coated with an anti-corrosion layer on the surface, and have good thermal conductivity. A heating device is usually arranged inside or on the surface of the roller body. Common heating methods include electric heating, steam heating or oil heating, etc., which can conduct heat to the polyurethane fiber fabric and the leather composite fabric, and can shape the glue between the polyurethane fiber fabric and the leather composite fabric, so that the polyurethane fiber fabric and the leather composite fabric can be hot-pressed and bonded, thereby forming ultra-fiber synthetic leather.

[0065] In this embodiment, two tensioning assemblies are symmetrically arranged in the second frame 5, and two slide grooves 9 are symmetrically arranged on the second frame 5. The tensioning assembly includes a first lifting assembly and a lifting rod 11. The lifting rod 11 is fixed to the output end of the first lifting assembly. Both ends of the lifting rod 11 are provided with positioning seats 7 that slide with the slide groove 9. Two tensioning shafts 8 are symmetrically arranged between the two positioning seats 7, and both ends of the tensioning shaft 8 are rotatably connected with the positioning seats 7. Starting the first lifting assembly can make the lifting rod 11 drive the two positioning seats 7 to slide in the two slide grooves 9, so that the two tensioning shafts 8 can be lifted and lowered, and then the tightness of the polyurethane fiber fabric and the leather composite fabric can be adjusted, which can improve the subsequent fitting quality of the polyurethane fiber fabric and the leather composite fabric.

[0066] When the adhesive fabric on the first unwinding shaft 38 is used up, it needs to be replaced. Two top plates 13 are symmetrically arranged at the top and bottom of the third frame 12, and an empty slot is arranged inside the top plate 13.

[0067] Starting the first driving motor 17 can make the first rotating shaft 18 drive the two first screws 19 to rotate. Through the action of the positive and negative thread structures, the two bases 16 can slide synchronously in opposite directions along the two first screws 19, so that the two third frames 12 can move symmetrically on the processing table 1. In this process, the block 27 on the transmission rod 25 and the block 27 on the fixed shaft 56 will both disengage from the grooves at both ends of the positioning rod 26, so that the positioning rod 26 can be disassembled. The retaining ring 30 is further rotated to remove the two retaining rings 30, and then the two fixing rings 29 can be disassembled, so that the first unwinding motor 36, the first rotating shaft 18, the first winding motor 31 and the first winding shaft 34 can be taken out separately, so that the adhesive fabric on the first unwinding shaft 38 can be replaced conveniently. After the fixing ring 29 is disassembled, one end of the second support rod 35 will be pulled out of the second fixed tube 37, one end of the first support rod 33 will be pulled out of the first fixed tube 32, and one end of the insertion rod 57 will be pulled out of the positioning ring 24.

Through the cooperation between the protrusions and the grooves, the fixing ring 29 can be installed more firmly on the positioning rod 26.

[0069] In this embodiment, two second driving motors 52 and guide rails 50 are symmetrically arranged on both sides of the fourth frame 39, and a movable seat 51 that slides with the guide rails 50 is fixedly arranged on the second unwinding motor 46 and the second winding motor 48, and a second rotating shaft 53 is provided at the output end of the second driving motor 52, and two second screws 54 with positive and negative tooth structures are symmetrically arranged on the second rotating shaft 53, and the two second screws 54 respectively pass through the two movable seats 51.

The output end of the second lifting assembly is provided with a push rod connected to the fixed frame 21, and both ends of the fixed frame 21 are provided with guide rods 23 that penetrate the top plate 13. As the first unwinding shaft 38 is unwound, the thickness of the bonding fabric on the first unwinding shaft 38 will become thinner. At this time, the clamping shaft 20 needs to be lowered, so that the bonding fabric can be in close contact with the bonding surface of the polyurethane fiber fabric and the leather composite fabric, thereby ensuring the cleaning effect of the bonding fabric on the polyurethane fiber fabric and the leather composite fabric.

[0072] In this embodiment, the unloading motor 3, the first winding motor 31, the first unwinding motor 36, the second driving motor 52, the second winding motor 48 and the second unwinding motor 46 can all adopt servo motors.

By adjusting the pressure of the air source, the propulsion speed of the telescopic cylinder can be changed. Reducing the air pressure can slow down the extension speed of the cylinder, thereby achieving slow propulsion.
