[0042] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0043] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0044] The existing glue layer has a limited thickness: the thickness of the single-layer coated glue layer is insufficient, which may lead to insufficient bonding strength. Especially in the parts that bear large tensile forces or frequent bending, delamination or cracking is likely to occur, and the bonding effect is unstable. When applying a single layer of coating, the glue may not fully penetrate into the fabric fibers, resulting in an unstable bonding effect and affecting the overall performance of the fabric. Therefore, to solve the above problems, the following technical solutions are proposed in this case:

[0045] Please refer to Figures 1 to 7 , the present invention provides a technical solution for a waterproof and moisture-permeable fabric laminating device: its structure includes: a drive roller group 3, a first winding roller 4, a second winding roller 5, and a third winding roller 6. The frame of the drive roller group 3 is connected to the first winding roller 4 and the second winding roller 5. The first winding roller 4 and the second winding roller 5 are movably connected to the hot pressing roller 2 installed between the drive roller group 3. The sheets output by the first winding roller 4 and the second winding roller 5 are pressed together by the hot pressing roller 2 and wound up by the third winding roller 6. A coater 1 is provided on the top of the hot pressing roller 2. The side seat 14 of the coater 1 is installed on the surface of the bracket of the drive roller group 3. A movable first adjustment seat 15 is provided on the top of the side seat 14. A horizontally arranged cross plate 11 is installed between the first adjustment seats 15, and a glue supply device 12 is fixed on the surface of the cross plate 11. A glue supply roller 13 is provided between the first adjustment seats 15. The glue supply rollers 13 are symmetrically arranged, and the two sides of the glue supply rollers 13 are engaged by gears. A glue distributor 302 is provided on the top of the coating roller 301 of the glue supply roller 13 and is connected to the glue supply device 12 through a pipeline.

[0046] The main structure of this device includes a drive roller group 3. A coater 1 and a hot pressing roller 2 are provided in the middle of the drive roller group 3, and a second winding roller 5, a first winding roller 4, and a third winding roller 6 are provided on both sides respectively. Specifically, the roller body inside the drive roller group 3 guides the fabric and the laminating direction, so that it passes through the coater 1 and is pressed together with the fabric and the laminate through the pressing roller body 22 between the auxiliary seat 21 and the second adjustment seat 23 of the hot pressing roller 2. A heat conducting ring 24 and a heater 25 are provided inside the pressing roller body 22. The heat conducting ring 24 generates heat through the heater 25 and then conducts the heat energy to the surface of the pressing roller body 22 to heat the fabric and the laminate, so as to thermally bond the two.

[0047] The structure of the coater 1 includes a side seat 14 installed on the inner surface of the drive roller group 3. A motor is installed inside the side seat 14, and the first adjustment seat 15 on the top is lifted and lowered by a lead screw. A cross plate 11 is installed between the first adjustment seats 15. A glue supply device 12 is arranged on the surface of the cross plate 11. The cross plate 11 is used for supporting the glue supply device 12. A pump body is provided inside the glue supply device 12. The pump body is connected to the glue supply roller 13 through a multi-way valve. The glue is coated more evenly through multi-channel glue delivery. The glue supply roller 13 wraps the coating roller 301 and the glue distributor 302. The coating roller 301 is used for pressing and coating, and the coating roller 301 is used for glue delivery.

[0048] The structure of the hot pressing roller 2 includes an auxiliary seat 21 installed on the bracket of the driving roller group 3 and a second adjusting seat 23. A motor is installed on the second adjusting seat 23 to control the clamping gap between the roller bodies 22 to change the pressing pressure, so as to avoid the glue overflow caused by excessive pressure.

[0049] The structure of the first adjusting seat 15 includes an adjusting motor 151. The adjusting motor 151 drives the main gear 152 to drive the main shaft 153 to rotate. The main shaft 153 passes through the connecting disk 313 of the second support arm 314 to drive the connecting disk 313 to rotate. The connecting disk 313 is nested with the adjusting hole 324 in the middle of the shaft disk 323 and meshes with the internal teeth of the shaft disk 323. A brush roller 312 is installed between the second support arm 314 and the auxiliary frame 321. Through the cooperation of the brush roller 312 and the flow dividing disk 311 installed on the tops of the second support arm 314 and the auxiliary frame 321, the rolling coating of the sheet material is carried out.

[0050] The axis of rotation of the auxiliary frame 321 is axially offset from the axis of rotation of the second support arm 314. Specifically, the axis of the auxiliary frame 321 is set at the center of the shaft sleeve 322 and is nested with the first adjusting seat 15 through the shaft sleeve 322. The axis of rotation of the second support arm 314 is the center of the connecting disk 313, and the connecting disk 313 is fixed by the synchronous shaft 315 to reduce the shaking of the second support arms 314 on both sides. The auxiliary frame 321 and the auxiliary arm 325 are cooperatively installed on both sides of the second support arm 314 and clamp it inside to improve stability. When the main shaft 153 drives the connecting disk 313 to rotate, one side of the second support arm 314 deflects. During the rotation of the connecting disk 313, the connecting disk 313 drives the shaft disk 323 to rotate in the opposite direction. The main purpose is that: during the process of double-sided glue coating, some fabrics have more pores and absorb more glue, and it is easy to cause glue overflow during rolling. Therefore, this device controls the gap between the brush roller 312 and the roller body 22 through the second support arm 314 and the auxiliary frame 321. When the gap on one side increases, the gap on the other side decreases, so as to quickly adjust the coating thickness and improve the convenience of use.

[0051] A flow dividing disk 311 for glue coating is arranged on the surfaces of the second support arm 314 and the auxiliary frame 321. The structure of the flow dividing disk 311 includes a positioning plate 116. An independent confluence groove 112 is arranged inside the positioning plate 116. The confluence groove 112 is connected with a connecting valve head 115. The glue flow in a single cavity is controlled separately through the confluence groove 112, and the contact between the glue and the air is reduced to extend the service time of the glue. The glue flows out through the front diversion slit 111 of the confluence groove 112. The diversion slit 111 is attached to the brush roller 312, so that a glue layer is formed on the surface of the brush roller 312 and is transferred to the surface of the sheet material.

[0052] In order to keep the surface of the brush roller 312 smooth at all times, a guide bar 113 is provided at the front end of the positioning plate 116 for the surface of the brush roller 312 to fit, and a guide inner groove 114 is provided in the middle of the guide bar 113 for the surface of the brush roller 312 to contact, which can keep the surface of the brush roller 312 smooth and improve the uniform coating of the glue during the coating process.

[0053] In order to reduce the shaking between the second support arm 314 and the auxiliary frame 321, the connecting plate 313 is nested with the first tooth plate 131 and the second tooth plate 132, and is tightly pressed by the limit spring 133 to reduce the shaking.

[0054] When the device is working:

[0055] s1: Place the fabric and the coating on the first winding roller 4 or the second winding roller 5 respectively, and pass through the transmission roller group 3 into the hot pressing roller 2 for clamping;

[0056] s2: The glue supply device 12 is connected to a glue barrel, and the operating speed of the pump body of the glue supply device 12 is adjusted to control the glue flow rate;

[0057] s3: The side seat 14 controls the first adjustment seat 15 to descend, so that the rubber supply roller 13 is in contact with the film and the surface of the fabric;

[0058] s4: The first adjustment seat 15 can be used to control the rotation of the rubber supply roller 13 according to the water absorption of the fabric to adjust the gap with the single-side surface;

[0059] s5: The processed fabric is wound up by the third winding roller 6.

[0060] The improved device drives the top first adjustment seat 15 to move up and down through the glue supply roller 13 to control the gap between the coating roller 301, the glue distributor 302 and the pressing roller body 22 to change the thickness of the glue, and simultaneously controls the movement trajectory of the brush rollers 312 on both sides through the first adjustment seat 15. The brush rollers 312 are respectively installed between the second support arm 314 and the frame formed by the auxiliary frame 321 and the auxiliary arm 325, and are linked by the shaft disk 323 and the connecting disk 313. When the brush roller 312 on one side is lifted, the brush roller 312 on the other side is pressed down, which can control the thickness of the glue layer when coating fabrics with different porosity, so that the total amount of glue on both sides can be better controlled when pressing the sheets.

[0061] In addition, the positioning plate 116 is provided with multiple confluence grooves 112 to cooperate with the connecting valve head 115. The connecting valve head 115 is connected to the glue supply device 12 to perform multi-bin glue distribution, which can avoid the problem of thick glue in the middle and less glue on both sides during the single-bin glue rolling process.

[0062] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present invention.

[0063] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
