Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a non-woven fabric-based tape coating equipment. Background Technology

[0002] Cloth-based tape uses polyethylene and gauze fiber as the base material through thermal lamination and is coated with high-viscosity synthetic adhesive. It has strong peel strength, tensile strength, grease resistance, aging resistance, temperature resistance, water resistance, and corrosion resistance. It is a high-adhesion adhesive with relatively strong adhesion.

[0003] A search revealed that CN216396920U discloses a double-sided coating device for nonwoven fabric-based adhesive tape. This device cleans the nonwoven fabric using a lint roller, applies adhesive using a coating roller, removes excess adhesive using a scraping mechanism, and finally winds it up using a roll roller. However, during winding, the tension of the nonwoven fabric gradually increases, which may cause the nonwoven fabric to stretch and deform, resulting in quality problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nonwoven fabric-based adhesive tape coating device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nonwoven fabric-based adhesive tape coating device includes a frame. A motor is fixedly connected to one outer wall of the frame. One end of the motor's output shaft passes through the frame and is connected to a take-up roller via a coupling. The upper surface of the frame is provided with a coating assembly for double-sided adhesive coating of the nonwoven fabric. The upper surface of the frame is also provided with an elastic assembly for supporting the take-up roller. A second U-shaped frame is fixedly connected to the upper surface of the frame. Slide grooves are provided on both sides of the second U-shaped frame. A first U-shaped frame is slidably connected within the slide grooves. A tension roller is rotatably connected within the first U-shaped frame. A lead screw is rotatably connected within one of the slide grooves, and the lead screw passes through the first U-shaped frame and is threadedly connected to it. A reduction motor is fixedly connected to the top of the second U-shaped frame, and one end of the reduction motor's output shaft passes through the second U-shaped frame and is fixed to the lead screw.

[0007] As a further embodiment of this utility model, the coating assembly includes two glue-applying rollers, both of which are rotatably connected to the frame body and aligned vertically. Two glue boxes are fixedly connected to the frame body, and the two glue-applying rollers are located between the two glue boxes. A sponge is fixedly connected to one of the opposite sides of each of the two glue boxes to spread glue across the surface of the glue-applying rollers. Multiple glue outlets are provided on the side of each of the two glue boxes near the sponge to allow glue to flow into the sponge. The upper surface of the frame body is provided with a glue-feeding assembly to deliver glue into the glue boxes.

[0008] As a further embodiment of this utility model, the glue conveying assembly includes a glue tank, which is fixedly connected to the upper surface of the frame. A water pump is fixedly connected to the upper surface of the frame. One end of the water pump inlet is connected to the glue tank through a pipe, and one end of the water pump outlet is fixedly connected to a material conveying pipe frame, which is connected to two glue boxes.

[0009] As a further embodiment of this utility model, the elastic component includes a square column, which is fixedly connected to the upper surface of the frame. A sliding sleeve is slidably connected to the outer side of the square column. An opening groove is provided at the top of the sliding sleeve, and the winding roller is located in the opening groove. A spring is fixedly connected to the top of the square column, and the spring is fixed to the sliding sleeve. A locking component is provided on one side of the sliding sleeve to fix the sliding sleeve.

[0010] As a further embodiment of this utility model, the locking assembly includes a pin, a through hole is provided on one side of the sliding sleeve, the pin is inserted into the through hole, and an insertion port is provided on one side of the square post, with the pin inserted into the insertion port.

[0011] As a further embodiment of this invention, two vertically aligned guide rollers are rotatably connected within the frame.

[0013] As a further embodiment of this utility model, two auxiliary rollers are rotatably connected within the frame, and the two glue-applying rollers are located between the two auxiliary rollers.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting tension rollers, when winding up the coated nonwoven fabric, the tension rollers keep the nonwoven fabric in a taut state. As the diameter of the nonwoven fabric increases during the winding process, the tension rollers can be moved to change the tension of the nonwoven fabric, thereby preventing the nonwoven fabric from being stretched and deformed during the winding process and improving the performance of the coating equipment.

[0016] 2. By setting up support components, the take-up roller is supported, thereby increasing the load-bearing capacity of the take-up roller, thus preventing deformation of the take-up roller during the winding process and improving the winding effect of nonwoven fabric.

[0017] 3. By using the lint roller, the lint roller cleans both sides of the nonwoven fabric before applying glue to both sides, thus preventing impurities on both sides of the nonwoven fabric from affecting the glue application effect and ensuring the cleanliness of the nonwoven fabric.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-4A nonwoven fabric-based adhesive tape coating device includes a frame 1. A motor is bolted to one outer wall of the frame 1. One end of the motor's output shaft passes through the frame 1 and is connected to a take-up roller 2 via a coupling. The upper surface of the frame 1 is provided with a coating assembly for double-sided adhesive coating of the nonwoven fabric. An elastic assembly supporting the take-up roller 2 is also provided on the upper surface of the frame 1. A second U-shaped frame 13 is bolted to the upper surface of the frame 1. Slide grooves 14 are provided on both sides of the second U-shaped frame 13. A first U-shaped frame 12 is slidably connected within the slide grooves 14. A tension roller 16 is rotatably connected within the first U-shaped frame 12. A lead screw 15 is rotatably connected within one of the slide grooves 14, and the lead screw 15 passes through and is threadedly connected to the first U-shaped frame 12. A reduction motor is bolted to the top of the second U-shaped frame 13, and one end of the reduction motor's output shaft passes through the second U-shaped frame 13 and is fixed to the lead screw 15. The coating assembly applies adhesive to both sides of the nonwoven fabric. The adhesive-coated nonwoven fabric is then passed under the tension roller 16 and wound onto the take-up roller 2. Under the action of the tension roller 16, the nonwoven fabric is kept taut. Simultaneously, the motor is started, driving the take-up roller 2 to rotate, thus winding the adhesive-coated nonwoven fabric. As the take-up roller 2 winds the nonwoven fabric, the diameter of the wound fabric increases. At this point, the reduction motor is started, driving the lead screw 15 to rotate slowly. The lead screw 15, through threaded engagement with the first U-shaped frame 12, causes the first U-shaped frame 12 to move towards each other along the slide groove 14. The first U-shaped frame 12 then drives the tension roller 16 upwards, changing its position and thus adjusting the tension of the nonwoven fabric. This prevents the nonwoven fabric from stretching and deforming during winding, improving the performance of the coating equipment.

[0025] In this invention, the coating assembly includes two coating rollers 17, both rotatably connected to the frame 1, and aligned vertically. Two glue boxes 19 are fixed inside the frame 1 by bolts, with the two coating rollers 17 positioned between them. A sponge 18 is adhered to one opposite side of each glue box 19 to distribute the glue across the surface of the coating rollers 17. Multiple outlets are provided on the side of each glue box 19 near the sponge 18 to allow glue to flow into the sponge 18. A glue delivery assembly is provided on the upper surface of the frame 1 to deliver glue into the glue boxes 19. The glue delivery assembly includes a glue tank 21, which is fixed to the upper surface of the frame 1 by bolts. A water pump 22 is also fixed to the upper surface of the frame 1 by bolts, with one end of the water pump 22's inlet connected to the glue tank 21 via a pipe. 1. The water pump 22 is connected to the outlet of the water pump 22. One end of the water pump 22 is fixed to the material conveying pipe frame 20 by bolts. The material conveying pipe frame 20 is connected to the two glue boxes 19. The water pump 22 draws glue from the glue tank 21 through the pipe and delivers the glue to the glue box 19 through the material conveying pipe frame 20. The glue entering the glue box 19 will flow into the sponge 18 through the glue outlet. Since the glue coating roller 17 is in contact with the sponge 18, the glue flows back to the glue coating roller 17 after filling the sponge 18, so that the glue covers the surface of the glue coating roller 17. The non-woven fabric is passed between the two glue coating rollers 17. During the winding process of the non-woven fabric, the two glue coating rollers 17 will rotate. The two glue coating rollers 17 will coat the glue in the sponge 18 onto both sides of the non-woven fabric, thereby coating the non-woven fabric with glue.

[0026] Specifically, the elastic component includes a square column 9, which is fixed to the upper surface of the frame 1 by bolts. A sliding sleeve 7 is slidably connected to the outer side of the square column 9. An opening groove 6 is provided on the top of the sliding sleeve 7, and the take-up roller 2 is located in the opening groove 6. A spring 11 is welded to the top of the square column 9, and the spring 11 is fixed to the sliding sleeve 7. A locking component is provided on one side of the sliding sleeve 7 to fix the sliding sleeve 7. The locking component includes a pin 8. A through hole is provided on one side of the sliding sleeve 7, and the pin 8 is inserted into the through hole. An insertion port 10 is provided on one side of the square column 9, and the pin 8 is inserted into the insertion port 10, so that the take-up roller 2 is located in the opening groove 6, and the sliding sleeve 7 supports the take-up roller 2, thereby increasing the load-bearing capacity of the take-up roller 2, thereby preventing the take-up roller 2 from deforming during the winding process, and improving the winding effect of the nonwoven fabric. When the nonwoven fabric is finished being wound... Then, pull the pin 8 to move it, so that the pin 8 is disengaged from the insertion port 10. At this time, the sliding sleeve 7 can be pulled down. The sliding sleeve 7 will squeeze the spring 11 and disengage the winding roller 2 from the opening slot 6. At this time, the wound non-woven fabric can be removed from the winding roller 2, which is convenient for the staff to remove the wound non-woven fabric. There are two vertically aligned guide rollers 5 rotatably connected inside the frame 1. There are also two lint-adhesive rollers 3 rotatably connected inside the frame 1 to clean the non-woven fabric. The two lint-adhesive rollers 3 are vertically aligned. Before applying glue to both sides of the non-woven fabric, the non-woven fabric will pass between the two lint-adhesive rollers 3, so that the two lint-adhesive rollers 3 will adhere and clean the impurities on both sides of the non-woven fabric, thereby ensuring that both sides of the non-woven fabric are clean. There are two auxiliary rollers 4 rotatably connected inside the frame 1, and two glue-applying rollers 17 are located between the two auxiliary rollers 4.

[0027] Working principle: When needed, the nonwoven fabric is fed through two guide rollers 5 and two lint rollers 3. The lint rollers 3 then adhere and clean impurities from both sides of the nonwoven fabric, ensuring cleanliness. The cleaned nonwoven fabric is then passed between two coating rollers 17, which coat both sides with adhesive. The coated nonwoven fabric is then passed under the tension roller 16 and wound onto the take-up roller 2. The tension roller 16 keeps the nonwoven fabric taut. Simultaneously, the motor is started, driving the take-up roller 2 to rotate. This causes the take-up roller 2 to take up the nonwoven fabric coated with adhesive. As the take-up roller 2 takes up the nonwoven fabric, the diameter of the nonwoven fabric roll increases. At this time, the geared motor is started, which drives the lead screw 15 to rotate slowly. The lead screw 15, through the thread engagement with the first U-shaped frame 12, drives the first U-shaped frame 12 to move towards each other along the slide groove 14. The first U-shaped frame 12 drives the tension roller 16 to move upward, changing the position of the tension roller 16, thereby adjusting the tension of the nonwoven fabric and preventing the nonwoven fabric from being stretched and deformed during the winding process, thus improving the use effect of the coating equipment.

[0028] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
