Description

Technical Field

[0001] The invention belongs to the technical field of Velcro composite equipment, and in particular relates to a composite equipment for an anti-falling Velcro and a use method thereof. Background Art

[0002] Velcro, also known as Magic Tape, is a connecting accessory widely used in daily life. The Velcro composite equipment is used to composite the Velcro and base fabric.

[0003] The Chinese invention patent with publication number CN109662839A discloses a waist patch production system and method, a Velcro pretreatment device, a base fabric pretreatment device and a compound device. The Velcro pretreatment device can supply Velcro and scrape glue on the Velcro, and the base fabric pretreatment device can provide the base fabric. The compound device can fix the pretreated Velcro on the base fabric. The device uses glue to bond the Velcro and the base fabric. The width of the Velcro is much smaller than the width of the non-woven fabric to avoid gaps in the glue application on both sides. However, dust and debris exist on the adhesive surface of the Velcro, which will hinder the effective contact between the hot melt adhesive and the Velcro and the base fabric, resulting in a reduction in the bonding area, thereby reducing the bonding strength. The presence of dust and debris may cause uneven distribution of the hot melt adhesive during the coating process, resulting in local over-thickness or over-thinness, further affecting the bonding effect. Summary of the invention

Compared with the single negative pressure adsorption of dust, the spiral winding setting of the cleaning cotton body can more effectively clean the fabric.

The first glue-scraping group is a cylinder and a scraper, and the cylinder controls the distance between the scraper and the glue-taking roller to scrape off the excess glue, ensuring that the glue transferred to the glue-applying roller is uniform. The pressing part is a cylinder and a pressure roller connected to the output end of the cylinder, and the surface of the pressure roller is sleeved with an elastic sleeve. The cylinder drives the pressure roller to apply pressure to the base fabric that is pressed against the glue roller for gluing, which can ensure close contact between the glue and the base fabric, promote the penetration and curing of the glue, and thus significantly enhance the bonding strength. Two groups of second glue-scraping components are symmetrically arranged on both sides of the base fabric and fixedly connected to the inner wall of the glue-applying box, which can effectively scrape off the glue overflowing on both sides, prevent the waste of glue and keep the working environment clean.

[0014] In the present technical solution, the first cylinder pushes out the side scraping part and contacts the side of the base fabric that has been glued. The side scraper, the baffle plate, the first fixed plate and the drainage guide plate are arranged so that the scraped side overflow glue can flow back into the glue liquid box. While scraping the overflow glue, the glue liquid can be drained back into the glue liquid box for reuse.

[0015] In the above technical solution, further, a heating part is arranged inside the inner wall of the glue box, the scraper, the first fixed plate, the baffle plate and the flow guide plate.

[0016] In the present technical solution, the heating part can be a heating device such as an electric heating wire or a heating roller to ensure that the glue in the glue box is in a liquid state and to ensure the gluing treatment. The scraper and the drainage guide plate are provided with a heating part and a first fixed plate to avoid the glue solidifying on the second scraper assembly after the overflow glue on both sides of the base fabric is scraped off, to ensure that the glue is in liquid state and falls back into the collection box below through the drainage guide plate, to avoid waste of glue and to ensure the quality of scraping glue.

By quickly lowering the temperature of the composite fabric, the first cooling component helps the hot melt adhesive to quickly take shape, reducing problems such as flow or deformation of the adhesive layer caused by excessive temperature. The air guide plate adopts a trapezoidal plate structure, with the two ends close to the air inlet and outlet on the same side, and the middle protrusion close to the composite surface passing through the middle. This design can fully guide the cooling air to concentrate on the composite fabric.

The cooling medium (such as cold water or coolant) in the cooling roller body can be replaced through pipeline circulation to maintain the continuity and stability of the cooling effect. The cooling medium changer can be a heat exchange device in the prior art. The design of the guide column and guide sleeve ensures the stability of the upper support frame when it moves.

[0049] In the present invention, the direction toward the first supply part 3 and the second supply part 4 is defined as the front side, the front end, the front part, and the direction toward the winding part 5 is defined as the rear side, the rear end, the rear part, and the rear part.

[0050] The drive box 6 is provided with driving components, such as motors, for the first supply part 3, the second supply part 4 and the winding part 5 to work. The supply part and the winding part 5 unwind and wind the base fabric 13, the hook and loop fabric 14 and the composite fabric 15, which are all prior arts and will not be elaborated. In the present invention, the first supply part 3 unwinds the base fabric 13, the second supply part 4 unwinds the hook and loop fabric 14, and before the base fabric 13 enters the gluing device 8, the first adhesive surface 9 to be glued is cleaned and dusted by the cleaning component, and before the pressing and compounding part 10, the cleaning component can clean the hook and loop fabric 14 on the hook and loop fabric 14 that is about to be pressed and compounded with the first adhesive surface 9 The second adhesive surface 11 is cleaned and dusted. By cleaning the first adhesive surface 9 on the base fabric 13, uneven coating due to the presence of dust and debris during gluing and local over-thickness or over-thinness can be avoided. By cleaning the second adhesive surface 11 on the Velcro fabric 14, it can be ensured that the first adhesive surface 9 and the second adhesive surface 11 are in full contact during pressing and compounding, thereby avoiding degumming and warping caused by dust and debris on the second adhesive surface 11. The bonding strength and uniformity of the Velcro fabric 14 and the base fabric 13 are effectively improved. Therefore, the Velcro can withstand greater tension and friction during use and is not easy to fall off or be damaged.

[0051] The present invention is also provided with a plurality of guide rollers 12, which can support and guide the fabric.

[0052] like Figure 2 and Figure 4As shown, the cleaning assembly includes a first cleaning roller 16 and a second cleaning roller 17 which are arranged between the drive box 6 and the fixed wall 7. The first cleaning roller 16 is arranged in front of the gluing device 8. The first cleaning roller 16 is rotatably arranged on the drive box 6. The first cleaning roller 16 and the first adhesive surface 9 on the base fabric 13 are arranged in contact with each other. The first cleaning roller 16 is a hollow tube body with adsorption holes 18 on the surface. The second cleaning roller 17 has the same structure as the first cleaning roller 16. The second cleaning roller 17 is arranged in front of the pressing composite part 10. The second cleaning roller 17 and the second adhesive surface 11 on the Velcro fabric 14 are arranged in contact with each other. The first cleaning roller 16 pipeline is connected to the dust collection box 19, and the dust collection box 19 is connected to the negative pressure generator 20.

[0053] The negative pressure generator 20 is a prior art. Negative pressure is generated in the dust collection box 19 through the negative pressure generator 20. The dust collection box 19 is connected to the inner cavity of the cleaning roller. Dust and dust on the bonding surface of the fabric are sucked in through the dust suction holes on the cleaning roller. Finally, the dust enters the dust collection box 19. The bonding effect is improved by cleaning the bonding surface.

[0054] On the opposite side of the first cleaning roller 16 of the base fabric 13 and on the opposite side of the second cleaning roller 17 of the hook and loop fabric 14, a support roller 53 is provided, which can support the fabric when the cleaning roller is cleaning to ensure the cleaning effect. The support roller 53 can also be replaced with a cleaning roller to clean both sides of the base fabric 13 and the hook and loop fabric 14, which is convenient for subsequent processes.

[0055] like Figure 4 As shown, it also includes a cleaning cotton body 21, which is spirally wound on the surface of the cleaning roller. The adsorption holes 18 arranged on the surface of the cleaning roller are arranged in an array along the length direction of the cleaning roller corresponding to the cleaning cotton body 21.

[0056] The cleaning cotton body 21 can be made of flexible materials such as sponges or brushes. The cleaning cotton body 21 has a soft texture and is friendly to the surface of the fabric. It can effectively clean the fabric without damaging the fabric. This design avoids the scratches or damage that may be caused to the fabric by hard materials. It is especially suitable for sensitive materials such as Velcro fabrics 14 and base fabrics. Compared with a single negative pressure to adsorb dust, the spiral winding setting of the cleaning cotton body 21 can more effectively clean the fabric. The adsorption holes 18 on the surface of the cleaning roller are arranged corresponding to the cleaning cotton body 21, forming an effective adsorption channel. When the negative pressure generator 20 is working, the dust can be more efficiently sucked into the dust collection box 19 through the adsorption holes 18, thereby improving the working efficiency of the entire dust removal system. In this embodiment, a plurality of first cleaning rollers are connected by pulleys and transmission belts, and a plurality of second cleaning rollers 17 are arranged in the same manner as the first cleaning rollers 16.

The first glue spreading scraper group 28 is fixedly provided on the side wall of the gluing box 22, and spreads the glue liquid on the glue roller after dipping the glue liquid, and also includes a pressing part 27, and the pressing part 27 can apply pressure to the base fabric 13 abutting against the gluing roller 26 for gluing, and a second glue scraping assembly 29 is provided above the glue box and at the rear side of the pressing part, and two groups of the second glue scraping assemblies 29 are symmetrically arranged on both sides of the base fabric 13 and fixedly connected to the inner wall of the gluing box 22, and the second glue scraping assembly 29 can scrape off the overflowed glue on both sides.

[0058] The first glue-scraping group 28 is fixedly arranged on the side wall of the glue box 22, and the glue on the glue roller 25 after being dipped in the glue is accurately scraped and evenly distributed, ensuring the uniform distribution of the glue on the surface of the glue roller 25. The first glue-scraping group 28 is a cylinder and a scraper, and the cylinder controls the distance between the scraper and the glue roller 25 to scrape off the excess glue, ensuring that the glue transferred to the glue roller 26 is uniform. The pressing part 27 is a cylinder and a pressure roller connected to the output end of the cylinder. The surface of the pressure roller is sleeved with an elastic sleeve. The cylinder drives the pressure roller to apply pressure to the base fabric 13 that is pressed against the glue roller 26 for gluing, which can ensure the close contact between the glue and the base fabric 13, promote the penetration and curing of the glue, and thus significantly enhance the bonding strength. Two groups of second glue-scraping components 29 are symmetrically arranged on both sides of the base fabric 13 and fixedly connected to the inner wall of the glue box 22, which can effectively scrape off the glue overflowing on both sides, prevent the waste of glue and keep the working environment clean. This design not only improves the material utilization rate, but also reduces the production cost.

[0059] like Figure 3 and Figure 5 As shown, the second scraper assembly 29 includes a mounting base 30 fixedly connected to the inner wall of the glue box 22, a first cylinder 31 is fixedly arranged between the mounting base 30 and the inner wall of the glue box 22, the output end of the first cylinder 31 passes through the mounting base 30 to connect to the side scraper part, the side scraper part includes a first fixed plate 32 connected to the output end of the first cylinder 31, a scraper 33 capable of scraping side overflow glue is fixedly arranged on the first fixed plate 32, a baffle plate 34 is arranged on the top of the scraper 33, a drainage guide plate 35 extending toward the glue box 24 below is arranged on the lower side of the scraper 33, and the drainage guide plate 35 is fixedly connected to the first fixed plate 32.

[0060] The first cylinder 31 pushes out the side scraping part and contacts the side of the base fabric 13 that has been glued. The side scraper 33, the baffle plate 34, the first fixed plate 32 and the guide plate 35 can make the scraped side overflow glue flow back into the glue box 24. While scraping the overflow glue, the glue can be drained back into the glue box 24 for reuse.

[0061] The inner wall of the glue liquid box 24, the scraper 33, the first fixed plate 32, the baffle plate 34 and the diversion guide plate 35 are all provided with a heating part 36. The heating part 36 can be a heating device such as an electric heating wire or a heating roller to ensure that the glue liquid in the glue liquid box 24 is in a liquid state and to ensure the gluing treatment. The scraper 33, the diversion guide plate 35 are provided with the heating part 36 and the first fixed plate 32 to avoid the glue liquid from solidifying on the second scraping glue assembly 29 after the glue overflow on both sides of the base fabric 13 is scraped off, and to ensure that the glue liquid is in a liquid state and falls back into the collection box below through the diversion guide plate 35, so as to avoid waste of glue liquid and ensure the scraping glue quality.

[0062] Second embodiment:

[0063] This embodiment provides a composite device of anti-falling Velcro, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0064] like Figure 2 and Figure 6 As shown, it also includes a first cooling component 37 arranged on the rear side of the pressing composite part 10, and the first cooling component 37 includes a cooling box 38 for the composite fabric 15 to pass through. The cooling box 38 is provided with an air inlet 39 and an air outlet 40 at both ends. The air inlet 39 pipeline is connected to a cooling fan 41, and both upper and lower sides are provided with an air guide plate 42 for guiding air to the composite fabric 15 passing through the middle. The air guide plate 42 is a trapezoidal plate structure, with both ends close to the air inlet 39 and the air outlet 40 on the same side, and a middle protrusion close to the composite fabric 15 passing through the middle.

[0065] The air inlet 39 and the air outlet 40 arranged at the upper and lower ends of the cooling box 38, combined with the connected cooling fan 41, form an efficient air circulation system. This design enables the cooling air to evenly and quickly cover the surface of the composite fabric 15, significantly accelerating the cooling and curing process of the hot melt adhesive. By quickly reducing the temperature of the composite fabric 15, the first cooling component 37 helps the hot melt adhesive to quickly take shape, reducing problems such as the flow or deformation of the adhesive layer caused by excessive temperature. The air guide plate 42 adopts a trapezoidal plate structure, with the two ends close to the air inlet 39 and the air outlet 40 on the same side, and the middle protrusion close to the composite surface passing through the middle. This design can fully guide the cooling air to act concentratedly on the composite fabric 15.

The support frames on both sides are open to each other, and a cooling roller body 46 is arranged in the support frame along the length direction of the composite fabric 15. The cooling roller body 46 can abut against the composite fabric 15. The cooling roller body 46 is a hollow structure. The cooling roller body 46 can accommodate a cooling medium inside. The cooling roller body 46 is connected to a cooling medium changer 47 through a pipeline.

[0069] The lower support frame 45 is fixedly connected to the device body 1 through the second fixed plate 48, and a third fixed plate 49 is horizontally arranged above the upper support frame 44. The third fixed plate 49 and the upper support frame 44 are slidably connected through guide columns 51 and guide sleeves 50. The third fixed plate 49 is fixedly connected to the device body 1, and a second cylinder 52 is arranged above the third fixed plate 49. The output end of the second cylinder 52 passes through the third fixed plate 49 to connect to the upper support frame 44.
