[0026] In order 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 in conjunction with the 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 ordinary technicians in this field without making creative work are within 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 invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] The existing adhesive layer thickness is limited: the adhesive layer thickness of a single-layer coating is insufficient, which may lead to insufficient bonding strength, especially in areas that are subjected to large tension or frequent bending, which are prone to degumming or cracking, and unstable bonding effect: when a single layer is coated, the glue may not be able to fully penetrate into the fabric fiber, resulting in unstable bonding effect and affecting the overall performance of the fabric. Therefore, in order to solve the above problems, this case proposes the following technical solutions: See also Figures 1 to 7The present invention provides a technical solution for waterproof and breathable fabric coating equipment: its structure includes: a transmission roller group 3, a first winding roller 4, a second winding roller 5, and a third winding roller 6. The frame of the transmission roller group 3 is connected with 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 with the hot pressing roller 2 installed between the transmission roller group 3. The sheet output by the first winding roller 4 and the second winding roller 5 is pressed by the hot pressing roller 2 and rolled up by the third winding roller 6. The top of the hot pressing roller 2 is provided with a coating Coating device 1, the side seat 14 of the coating device 1 is installed on the bracket surface of the driving roller group 3, and a movable first adjustment seat 15 is arranged 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 arranged between the first adjustment seats 15. The glue supply roller 13 is symmetrically arranged, and the glue supply rollers 13 on both sides are matched through gears. A glue distributor 302 is provided on the top of the coating roller 301 of the glue supply roller 13, which is connected to the glue supply device 12 through a pipeline.

[0029] The main structure of the device includes a transmission roller group 3, a coater 1 and a hot pressing roller 2 are arranged in the middle of the transmission roller group 3, and a second winding roller 5, a first winding roller 4, and a third winding roller 6 are arranged on both sides. Specifically, a roller body is arranged inside the transmission roller group 3 to guide the direction of the fabric and the coating, so that it passes through the coater 1 and passes through the roller body 22 between the auxiliary seat 21 and the second adjustment seat 23 of the hot pressing roller 2. The fabric and the coating are pressed by rolling the roller body 22. A heat conduction ring 24 and a heater 25 are arranged inside the roller body 22. The heat conduction ring 24 generates heat through the heater 25 and then conducts the heat energy to the surface of the roller body 22 so that the roller body 22 heats the fabric and the coating, thereby heat-sealing the two.

[0030] The structure of the coater 1 includes a side seat 14 installed on the inner surface of the driving roller group 3, a motor is installed inside the side seat 14, and the first adjustment seat 15 on the top is raised and lowered by a screw rod. A horizontal plate 11 is installed between the first adjustment seats 15, and a glue supply device 12 is arranged on the surface of the horizontal plate 11. The horizontal plate 11 is used to support the glue supply device 12. A pump body is arranged inside the glue supply device 12, and the pump body is connected to the glue supply roller 13 through a multi-way valve. The glue is transported through multiple channels to make the coating of glue more uniform. 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 transportation.

[0031] 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 adjustment seat 23. The second adjustment seat 23 is equipped with a motor for controlling the clamping gap between the pressing roller bodies 22 to change the pressing pressure and avoid glue overflow caused by excessive pressure.

[0032] The structure of the first adjustment seat 15 includes an adjustment motor 151, which 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 adjustment hole 324 in the middle of the shaft disk 323 and meshes with the inner teeth of the shaft disk 323. A brush roller 312 is installed between the second support arm 314 and the auxiliary frame 321. The brush roller 312 cooperates with the diverter disk 311 installed on the second support arm 314 and the top of the auxiliary frame 321 to perform rolling coating of the sheet.

[0033] The axis of the auxiliary frame 321 is axially staggered with the axis of the second support arm 314. Specifically, the axis of the auxiliary frame 321 is set at the center of the sleeve 322, and is nested with the first adjustment seat 15 through the sleeve 322. The axis 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 installed on both sides of the second support arm 314 to clamp it inside to improve stability. When the second support arm 314 rotates, one side of the second support arm 314 is offset. During the rotation of the connection disk 313, the connection disk 313 drives the shaft disk 323 to rotate in the opposite direction. The main purpose is that in the process of double-sided glue coating, some fabrics have more pores and absorb more glue, which is easy to cause glue overflow during rolling. Therefore, the device controls the gap between the brush roller 312 and the pressure 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, thereby being able to quickly adjust the coating thickness and improve the convenience of use.

[0034] A diverter plate 311 for coating glue is arranged on the surface of the second support arm 314 and the auxiliary frame 321. The structure of the diverter plate 311 includes a positioning plate 116. An independent confluence groove 112 is arranged inside the positioning plate 116. The confluence groove 112 is connected to the connecting valve head 115. The confluence groove 112 is used to individually control the glue flow in a single cavity, reduce the contact between the glue and the air, and extend the use time of the glue. The confluence groove 112 allows the glue to flow out through the front guide slot 111. The guide slot 111 is fitted with the brush roller 312, so that a glue layer is formed on the surface of the brush roller 312 and transferred to the surface of the sheet.

[0035] 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, thereby maintaining the flatness of the surface of the brush roller 312 and improving the uniform coating of the glue during the coating process.

[0036] 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 toothed plate 131 and the second toothed plate 132, and is pressed by the limit spring 133 to reduce the shaking.

[0037] When the device is working: 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 to enter the hot pressing roller 2 for clamping; s2: The glue supply device 12 is connected to an external glue barrel, and the operating speed of the pump body of the glue supply device 12 is adjusted to control the glue flow rate; s3: the side seat 14 controls the first adjustment seat 15 to descend, so that the rubber supply roller 13 fits the coating and the surface of the fabric; s4: According to the water absorption of the fabric, the first adjustment seat 15 can be used to control the rubber supply roller 13 to rotate and adjust the gap with the single-side surface; s5: The processed fabric is rolled up by the third winding roller 6.

[0038] 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 through 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, so that the thickness of the glue layer can be controlled when coating fabrics with different porosity, so that the total amount of glue on both sides can be better controlled when the sheets are pressed together.

[0039] In addition, the positioning plate 116 is provided with a plurality of 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 single-bin glue rolling.

[0040] The above only describes the basic principles and preferred implementations of the present invention. Those skilled in the art may 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.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
