[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] Example: A composite adhesive coating device, such as Figure 1 and Figure 2 As shown, the equipment includes a main body 1, which comprises a first feeding rack 101, a second feeding rack 102, a third feeding rack 103, a laminating chamber 104, a heating chamber 105, and a discharge rack 106. The first feeding rack 101 and the third feeding rack 103 are used to convey fabric, while the second feeding rack 102 is used to convey membrane materials. The membrane materials include EPE film, PP film, TPU film, PU film, TPE film, or PTFE film. The first feeding rack 101, the second feeding rack 102, and the third feeding rack 103 are all equipped with straightening devices and cross-tensioning devices. The tension frame 2 is rotatably connected to the flattening roller 3. The surface of the flattening roller 3 is symmetrically provided with two flattening threads extending from the middle to both ends. The two flattening threads are inclined in opposite directions. The fabric and film materials output from the first feeding frame 101, the second feeding frame 102, and the third feeding frame 103 are all driven by the frictional traction force generated when the flattening roller 3 rotates to perform flattening operation, thereby ensuring the flatness of the fabric and film materials during the conveying process. The second feeding frame 102 is also provided with a release roller 18 for peeling off the release paper.
[0019] like Figure 1 , Figure 2 and Figure 5As shown, the correction device includes a probe and an automatic adjustment assembly 4. The probe is a high-precision optical probe with a maximum detection angle of 120°. The probe is located in the middle of the side of the tension frame 2 near the flattening roller 3, ensuring that the detection range covers the output path of the fabric or film. The detection accuracy of the probe is ±0.1mm. When the probe detects a positional deviation of the film or fabric exceeding 0.3mm, it transmits a signal to the automatic adjustment assembly 4. The automatic adjustment assembly 4 consists of two symmetrically arranged electric push rods 401 and two push plates 402. The electric push rods 401 are electrically connected to the probe via a controller. The push plates 402 are connected to the electric push rods 401. The constricted end is fixedly connected, and the push plate 402 has a through groove 9. The push plate 402 is slidably connected to the feeding rack 101, feeding rack 2 102 or feeding rack 3 103 through the through groove 9. The two push plates 402 of the same automatic adjustment component 4 abut against the two sides of the fabric or film material respectively. When the electric push rod 401 receives the signal transmitted by the probe, it drives the push plate 402 to move along the width direction of the equipment body 1, thereby pushing the fabric or film material to adjust its position. This effectively solves the problem of alignment deviation and unstable tension that easily occur when multiple materials are composited in traditional equipment, reduces the risk of misalignment during composite, and improves the flatness and dimensional accuracy of the composite fabric.
[0020] like Figures 1-3 As shown, the laminating chamber 104 is equipped with a direct coating device 5 and a roller coating and flattening device 6. A top loading path and a bottom loading path are provided between the loading rack 3 103 and the laminating chamber 104. Several guide rollers are rotatably connected inside the laminating chamber 104, including guide roller one 10, guide roller two 11, guide roller three 12, guide roller four 13, guide roller five 14, and guide roller six 15. The fabric output from the loading rack three 103 sequentially passes through the heating chamber 105, guide roller six 15, guide roller five 14, guide roller two 11, and guide roller one 10 to form the bottom loading path. The fabric output from the loading rack three 103 sequentially passes through guide roller four 13, guide roller three 12, guide roller five 14, guide roller two 11, and guide roller one 10 to form the top loading path. The fabric conveyed by the top loading path directly enters the laminating chamber 104 for lamination. The bottom loading path... The fabric conveyed by the conveyor is preheated in the heating chamber 105 and then directly coated in the laminating chamber 104 before lamination. The differentiated preheating design of the top and bottom feeding paths, combined with the direct coating device 5 and the roller coating and flattening device 6, forms a combined coating scheme to adapt to the needs of different materials during lamination. The feeding rack 3 103 is equipped with a material identification sensor. The material identification sensor identifies the material by analyzing the unique absorption and reflection of light by the molecular structure of the fabric through near-infrared spectroscopy. The material identification sensor determines the different materials of the fabric, which makes it easier for the operator to convey the fabric into the top or bottom feeding path and select whether preheating is required. This allows fabrics with poor strength, such as nylon fabrics, to have their yarn fixation effect effectively improved after heating and coating. Cotton and linen fabrics do not require preheating and are directly laminated through the top feeding path.
[0021] likeFigures 1-4 As shown, the roller coating and flattening device 6 includes a dispensing roller 601, a composite roller 602, and a composite roller 603. The surface of the dispensing roller 601 is arrayed with several through holes 7, and several glue outlet tubes 8 are arranged inside the dispensing roller 601. The glue outlet of the glue outlet tube 8 communicates with the through holes 7. The direct coating device 5 includes a coating roller 501, a pressing roller 502, and a glue outlet tube 503. The bottom surface of the pressing roller 502 is higher than the bottom surface of the coating roller 501, so that the pressing roller 502 does not contact the fabric. A glue storage area 19 is formed between the coating roller 501 and the pressing roller 502. The glue outlet of the glue outlet tube 503 is located above the glue storage area 19. Both ends of the pressing roller 502 and the coating roller 501 are open... A ring groove 16 is provided, and a baffle plate 17 is detachably connected in the ring groove 16 on the same side as the extrusion roller 502 and the glue coating roller 501 to limit the loss of glue in the glue storage area 19. The glue output of the first glue outlet pipe 8 and the second glue outlet pipe 503 is adjusted by a gear pump. The film material output from the second loading rack 102 passes through the release roller 18 to peel off the release paper and then passes through the second guide roller 11 and the first guide roller 10 in sequence, so as to adhere to the fabric output from the third loading rack 103. The glue dot roller 601 coats the fabric output from the first loading rack 101 with dotted glue. The fabric output from the first loading rack 101 passes through the first composite roller 602 and the first guide roller 10 in sequence, and the glue coating roller 501 directly coats the fabric output from the third loading rack 103.
[0022] like Figure 1 and Figure 2As shown, composite roller 1 602 and composite roller 2 603 are symmetrically arranged vertically. Several guide rollers drive the film material and fabric to be horizontally conveyed between composite roller 1 602 and composite roller 2 603. Composite roller 1 602 is driven to move up and down along the height direction of the equipment body 1 by a hydraulic device, which includes components such as a hydraulic pump, hydraulic valve, oil tank, and hydraulic cylinder. The hydraulic pump draws hydraulic oil from the oil tank and sends it into the hydraulic cylinder. The extension and retraction of the hydraulic cylinder drives composite roller 1 602 to move up and down. The glue dot roller 601 applies glue to the fabric and is then pressed and flattened by composite roller 1 602 and composite roller 2 603. The pressure generated during hot pressing can be adjusted by adjusting the distance between composite roller 1 602 and composite roller 2 603. The amount of glue applied by the glue roller 601 and the composite chamber can be controlled. The pressure of 104 can control the thickness of the adhesive layer, meeting the composite requirements of thin adhesive layer coating. Composite roller 1 602 and composite roller 2 603 are hollow inside. The inner peripheral walls of composite roller 1 602 and composite roller 2 603 are provided with spiral channels. Heat-conducting oil pipes are arranged in the spiral channels. Heating oil is circulated in the heat-conducting oil pipes by an oil pump. The heating oil is electrically heated and used to heat according to the fabric composite requirements. Composite roller 1 602 and composite roller 2 603 maintain a constant temperature during the extrusion process. The heating temperature is controlled at 100-120 degrees. By flexibly adjusting the composite temperature, it can avoid the shrinkage and deformation of film materials with poor heat resistance, such as EPE film, due to high temperature composite, and can also improve the composite strength through heating. The unloading rack 106 is used to wind up the composite fabric.
[0023] like Figures 2-4 As shown, the adhesive output from dispensing tube 8 and dispensing tube 503 are both environmentally friendly solvent-free hot melt adhesives. When laminating PTFE films, which are prone to releasing harmful substances at high temperatures, laminating rollers 602 and 603 do not require heating, fundamentally avoiding the release of harmful substances during the high-temperature lamination of traditional PTFE films. This aligns with current green production concepts. Furthermore, by precisely controlling the lamination temperature and pressure, the original properties of the EPE and PP films are effectively protected, improving the washability of the composite fabric. This addresses the industry pain point of the sharp performance decline of traditional EPE or PP film composite fabrics after washing, and the resulting fabric possesses excellent properties. Excellent breathability and comfortable feel expand the application scenarios of composite fabrics in high-end clothing, outdoor products and other fields. This equipment can flexibly adjust the winding method and material feeding path according to the requirements of the number of composite layers, fabric thickness and other needs. It is also compatible with the composite production of various materials such as EPE film, PP film, TPU film, PU film, TPE film, PTFE film, nylon fabric, cotton and linen fabric and so on. The feeding rack 101 and feeding rack 202 can select to convey fabric or film material according to production needs. There is no need to frequently change equipment components, which significantly improves the versatility and production efficiency of the equipment and reduces the equipment investment cost for enterprises to produce a variety of fabrics.
[0024] A processing technology for a composite adhesive coating equipment, such asFigures 1-5 As shown, operating a composite adhesive coating device includes the following steps: S1: The two different fabrics after being rolled up are respectively fed onto the feeding rack 101 and the feeding rack 3 103. The film material to be laminated is rolled up and fed onto the feeding rack 2 102. The fabric output from the feeding rack 3 103 is selected to enter the top feeding path or the bottom feeding path after being judged by the material identification sensor. The fabric fed into the bottom feeding path is preheated in the heating chamber 105 before entering the lamination chamber 104. S2: The flatness of the film and fabric during conveying is ensured by the flattening roller 3. The positional deviation of the film and fabric during conveying is detected and corrected by the cooperation of the probe and the automatic adjustment component 4, which drives the film and fabric to automatically align. S3: The fabric output from the feeding rack 3103 is first directly coated by the direct coating device 5 before lamination; S4: The fabric output from the feeding rack 101 is first dotted by the dispensing roller 601 before lamination. The fabric and film to be laminated are conveyed together between the lamination roller 1 602 and the lamination roller 2 603 after the conveying direction is changed by several guide rollers. The lamination roller 1 602 and the lamination roller 2 603 maintain a constant temperature and hot press the overlapping fabric and film to drive the dotted adhesive liquid to spread out to form a full coating. The lamination operation is completed after the adhesive layer is cured. S5: The composite fabric is wound up via the unloading rack 106. In step S1, the preheating temperature is different for different types of fabrics. When the fabric is a thin chemical fiber fabric, the preheating temperature is controlled at 40-60℃, and when the fabric is a thick chemical fiber fabric, the preheating temperature is controlled at 60-80℃.
[0025] The fabrics output from loading rack 101 and loading rack 3 103 are respectively set as fabric 1 and fabric 2. The membrane materials output from loading rack 2 102 include film A, film B and film C. Film A, film B and film C are any one of EPE film, PP film, TPU film, PU film, TPE film or PTFE film and are different types. The specific types of composite materials in step S4 include: A. Any TPU film, PU film or TPE film applied alone to any fabric one or fabric two; B. A three-in-one combination of any TPU film, PU film, or TPE film with fabric one and fabric two; C. A single-layer application of any EPE film, PP film, or PTFE film with any fabric one or fabric two; D. A three-in-one combination of any EPE film, PP film, or PTFE film with fabric 1 and fabric 2.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
