The movement of the buffer plate is doubly buffered, thereby improving the buffer strength, fully avoiding the artificial leather from being excessively stressed and breaking, and playing a role in protecting the artificial leather.

[0017] When the top plate moves upward a large distance, the force exerted on the bottom surface of the artificial leather is greater, so that when the top plate presses against the artificial leather, it scrapes the bottom surface of the artificial leather toward the rear side, which can flatten the artificial leather. When the artificial leather enters the flattening roller and the constant tension shaft, it is subjected to force toward the rear side, thereby tightening the artificial leather, making its surface flatter during traction and achieving higher winding quality. At the same time, when the top plate rotates toward the rear side, the artificial leather can be relatively loosened. At the same time, the top plate rotates toward the rear side and moves upward at the same time, thereby ensuring the tension and tightening force on the artificial leather and further improving the winding quality of the artificial leather.

[0029] The one-to-three dehumidification vacuum drying unit is connected to the three ABC hopper pipelines.

There are two pipelines, one is the water inlet pipe and the other is the water outlet pipe. The spreading frame is located on one side of the rubber roller. The trimming device station is located on both sides of the traction roller section and is used to cut off excess edge materials and crush them. The trimming device station is connected to the B hopper.

[0030] The preparation process includes the following steps:

[0031] Step S1, introduce the TPEE material into a one-to-three dehumidification vacuum drying unit, and continuously add material for drying, and then introduce it into the three hoppers ABC based on two-stage hot air drying in real time and quantitatively and continuously;

[0032] Step S2, the material enters the electric heating screw, and the corresponding screw co-extrudes three layers, namely the bottom layer thermal composite high polarity modified TPEE, the conventional middle layer TPEE and the surface layer modified colored TPEE, thereby extruding and molding;

[0033] Step S3, the extruded material enters the mold and the rubber roller step surface, and the chiller unit uses a one-to-three form to introduce cooling water into the stripping roller section, the pattern roller section and the rubber roller, and at the same time introduces the polyester fabric into the pattern roller section and the rubber roller, and the fabric and the film on the rubber roller surface are thermally laminated, thereby realizing the glue-free lamination and thermal lamination sections, that is, saving a glue lamination process, and the fabric is recycled, which is more energy-saving and environmentally friendly;

[0034] Step S4, using the heat energy of the film above 200 degrees to directly heat-repair the film into a cloth-plastic pattern artificial leather;

[0035] Step S5, the artificial leather is then pulled by the pulling roller section, and the edge material is cut off by the trimming device station, and then the edge material is crushed, and the crushed edge material is sent to the B hopper for reuse through the fan and the pipeline;

[0036] Step S6, the artificial leather is then introduced into the flattening expansion roller to be flattened, and then introduced into the automatic double-station winding air expansion shaft through the constant tension frame;

[0037] Step S7: Automatically reel in, package online, put on shelves, store in warehouse, and wait for shipment.

[0038] The traction roller section in step S5 includes two bases 1, a flattening roller shaft 2, a constant tension shaft 3, a detector 4, a support plate 5 and a tension chamber 6;

[0039] The flattening roller 2 and the constant tension shaft 3 bearings are installed between the two bases 1, the detector 4 is fixedly installed above the left base 1, the support plate 5 is fixedly installed between the two bases 1, the tension chamber 6 is fixedly installed above the support plate 5, the inner wall of the tension chamber 6 is fixedly installed with a motor 61, and a notch is opened on the top, a buffer chamber 62 is fixed at the bottom of the inner wall of the tension chamber 6, a buffer plate 621 is slidably connected to the inner wall of the buffer chamber 62, a buffer rod 622 is fixedly installed above the buffer plate 621, a telescopic joint 623 is fixed to the upper end of the buffer rod 622, a support block 624 is fixed to the upper end of the telescopic joint 623, a support rod 625 is installed on the internal bearing of the support block 624, and a top plate 63 is fixed to the upper end of the support rod 625;

[0040] A toothed plate 64 is fixed to the right side of the buffer rod 622, a gear 611 is fixed to the output end of the motor 61, and is meshed with the toothed plate 64. A loose detection module is provided inside the detector 4, and the loose detection module is electrically connected to the motor 61. The loose detection module is used to detect whether the artificial leather is loose during the traction process through the detector 4, and control the rotation angle of the motor 61 according to the reduction amplitude of the artificial leather plane;

[0041] The artificial leather is pulled through the pulling roller section, and the artificial leather first passes through the flattening roller 2, and then enters the subsequent process through the constant tension shaft 3. When pulling the artificial leather, the detector 4 detects whether the artificial leather is loose during the pulling process through the loose detection module. When looseness occurs, the driving motor 61 is operated, and the motor 61 drives the gear 611 to rotate. The gear 611 drives the tooth plate 64 to move upward through engagement, and the tooth plate 64 drives the telescopic joint 623 to move upward through the buffer rod 622. The telescopic joint 623 drives the support rod 625 to move upward through the support block 624, thereby driving the top plate 63 to move upward, and making the top plate 63 contact with the bottom surface of the artificial leather, holding the bottom surface of the artificial leather upward, providing tension, thereby preventing the winding quality from being affected by the looseness, and detecting the degree of looseness through the loose detection module. The looser the artificial leather is, the greater the rotation angle of the motor 61 is, so that the top plate 63 moves upward to provide greater tension to the bottom surface of the artificial leather, thereby ensuring the winding quality.

[0042] The surface of the buffer plate 621 is provided with two through holes, and the buffer plate 621 is connected to the upper part of the inner wall of the buffer cavity 62 by a spring;

[0043] A hydraulic chamber 65 is fixed on the right side of the bottom of the inner wall of the tension chamber 6, a hydraulic plate 651 is slidably connected to the inner wall of the hydraulic chamber 65, a hydraulic rod 652 is fixed above the hydraulic plate 651, a tooth plate 2 66 is fixed on the upper end of the hydraulic rod 652, and the tooth plate 2 66 is meshed with the gear 611;

[0044] The bottom of the hydraulic chamber 65 is connected to the top of the buffer chamber 62 by a pipeline;

[0045] When the buffer rod 622 moves upward, it drives the buffer plate 621 to slide upward along the inner wall of the buffer chamber 62, and the spring is deformed by force, providing initial buffering for the upward movement of the top plate 63, thereby preventing the artificial leather from being damaged by excessive force. When the gear 611 rotates, it drives the tooth plate 2 66 to move downward through meshing. The tooth plate 2 66 drives the hydraulic plate 651 to slide downward along the inner wall of the hydraulic chamber 65 through the hydraulic rod 652. The liquid under the hydraulic plate 651 is squeezed and enters the interior of the buffer chamber 62 through the pipeline. When the buffer plate 621 moves upward, the liquid is squeezed and flows between the buffer plates 621 through the through holes, thereby doubly buffering the movement of the buffer plate 621, improving the buffering strength, and fully avoiding the artificial leather from being excessively stressed and fractured, thereby protecting the artificial leather.

[0046] Telescopic rods 67 are pin-connected to the front and rear sides of the inner wall of the tension chamber 6 , and the front ends of the two telescopic rods 67 are pin-connected to the front and rear sides of the support rod 625 , respectively.

[0047] A liquid inlet pipe and a liquid outlet pipe are connected between the rear telescopic rod 67 and the upper part of the hydraulic chamber 65. A pressure valve is arranged in the liquid inlet pipe, and a control valve is arranged in the liquid outlet pipe.

[0048] When the top plate 63 moves upward a large distance, the force exerted on the bottom surface of the artificial leather is large. At this time, the angle of rotation of the motor 61 is large, so that the gear plate 2 66 is driven to move downward a large distance through the engagement of the gear 611 with the gear plate 2 66, and the hydraulic plate 651 moves downward a large distance. The negative pressure generated above it reaches the pressure bearing limit of the pressure valve, and the pressure valve opens. The gas in the telescopic rod 67 on the rear side is extracted, causing the telescopic rod 67 to shorten rapidly, thereby pulling the support rod 625 to rotate slightly to the rear side through the pin shaft, thereby driving the top plate 63 to move backward, so that when the top plate 63 pushes against the artificial leather, it scrapes the bottom surface of the artificial leather toward the rear side, which can play a role in flattening the artificial leather. When the artificial leather enters the flattening roller 2 and the constant tension shaft 3, it is subjected to a force toward the rear side, thereby tightening the artificial leather, making its surface flatter during traction and having a higher winding quality.

[0049] A chamber 68 is fixed to the left side of the inner wall of the tension chamber 6, a sliding plate 681 is slidably connected to the inner wall of the chamber 68, a connecting plate 69 is fixed to the left side of the bottom of the support block 624, and a connecting rod is fixed between the sliding plate 681 and the connecting plate 69;

[0050] The bottom left side of the chamber 68 is connected to the bottom right side of the chamber 68 by a pipeline;

[0051] Through the above steps, the hydraulic plate 651 moves downward a large distance, and the liquid under the hydraulic plate 651 is squeezed and fully enters the buffer chamber 62. The liquid in the buffer chamber 62 is large and filled. After filling, the excess liquid enters the chamber 68 through the pipeline, and the hydraulic pressure pushes the sliding plate 681 to move upward, and the connecting plate 69 is driven to move upward through the connecting rod, and the connecting plate 69 drives the support block 624 to move upward, so that the top plate 63 moves toward the rear side and moves upward at the same time. At the same time, because the motor 61 is in a stopped state, the telescopic joint 623 is stretched by the force, so that the top plate 63 moves upward. At this time, the top plate 63 has a greater force to support the bottom surface of the artificial leather. At the same time, when the top plate 63 rotates to the rear side, it can relatively loosen the artificial leather. At the same time, the top plate 63 rotates to the rear side and moves upward, ensuring the tension and tightening force on the artificial leather, and further improving the winding quality of the artificial leather.
