Description

Technical Field

[0001] The utility model belongs to the field of production equipment for hook-and-loop fasteners, and particularly relates to a glue applicator for the production of hook-and-loop fasteners. Background Art

[0002] A hook-and-loop fastener consists of two parts. One part is the surface with small hooks (usually called the "hook surface"), and the other part is the surface with small loops (called the "fluffy surface" or "loop surface"). These two parts can be closely adhered together through the mechanical combination of hooks and loops. For use, glue is applied to the back of the hook-and-loop fastener, and a release paper is pasted on the glue surface. The release paper can effectively protect the sticky surface of the hook-and-loop fastener and prevent pollutants such as dust and stains from contacting the glue. In actual applications, users only need to peel off the release paper to expose the sticky back and conveniently paste the hook-and-loop fastener at the desired position.

[0003] The Chinese patent with the publication number CN213529384U applies glue to the back of the magic tape (i.e., hook-and-loop fastener) through an immersion roller and a glue applicator roller. There are problems that the amount of glue applied is not easy to control, and glue liquid is likely to overflow from the sides, which affects the adhesion to the release paper and also makes the appearance of the hook-and-loop fastener untidy. Utility Model Content

[0004] The purpose of the present utility model is to provide a glue applicator for the production of hook-and-loop fasteners aiming at the above-mentioned existing technical problems, achieving the effects of controllable glue application amount, uniform glue application, and avoiding glue liquid overflow from the sides.

[0005] In view of this, the present embodiment of the utility model provides a glue applicator for the production of hook-and-loop fasteners, which includes a box body. Openings for the belt body and the release paper to pass through are provided on both sides of the box body. A plurality of guide rollers are rotatably arranged in the box body. A glue liquid tank is arranged in the box body. A dipping roller is arranged on the glue liquid tank for dipping. An upper glue roller is arranged in abutment with the dipping roller. The glue applicator further includes a pressing assembly. The pressing assembly includes brackets arranged on both sides. A connecting seat is arranged on the brackets in a height-adjustable manner. A pressing roller is rotatably connected to the connecting seat. The pressing roller is abutted against the upper end surface of the belt body. Scraping glue assemblies are arranged at both ends of the belt body, and the scraping glue assemblies can scrape off the overflowing glue at the edges of the belt body.

[0006] In this technical solution, the dipping roller dips the glue liquid in the glue liquid tank, and the upper glue roller arranged above in abutment smears the glue liquid on the lower surface of the belt body. By setting the pressing assembly, the upper end surface of the belt body is pressed in cooperation with the upper glue roller to ensure that the glue liquid on the lower surface of the belt body is evenly smeared. At the same time, on the rear side of the pressing assembly in the belt body transmission direction, scraping glue assemblies are arranged on both sides of the belt body, which can scrape off the overflowing glue at the edges of the belt body after being pressed by the pressing assembly. The glue application amount of the present utility model can be controlled, and the glue can be evenly smeared on the bottom of the belt body, and the overflowing glue at the edges of the belt body can be scraped off.

[0007] In the above technical solution, further, the gantry is respectively arranged on both sides of the glue tank. A connecting seat is slidably arranged on the gantry. A first screw rod is fixedly connected to the top of the connecting seat. The first screw rod passes through the top of the gantry and is threadedly connected to a sleeve. The sleeve is rotatably connected to a digital position display. The digital position display is fixedly arranged on the top of the gantry. A handwheel is sleeved and connected to the sleeve.

[0008] In the above technical solution, further, first sliding grooves are arranged on both sides of the connecting seat, and guide sliding strips are arranged on the gantry corresponding to the first sliding grooves.

[0009] In this technical solution, when it is necessary to adjust the amount of glue applied or to apply glue to hook-and-loop tapes of different thicknesses, it is necessary to adjust the height of the pressing roller. Rotate the handwheel to drive the sleeve to rotate. The first screw rod threadedly connected to the sleeve drives the connecting seat to move in the gantry in the height direction. The operator can also accurately adjust the height of the pressing roller by observing the value displayed on the digital position display. The digital position display is a prior art, so it will not be elaborated here.

[0010] In the above technical solution, further, the glue scraping assembly includes a first air cylinder. The first air cylinder is fixedly arranged on the inner wall of the box body. The output end of the first air cylinder is connected to a glue scraping block body. The glue scraping block body can abut against the side of the belt body and scrape the glue liquid on the side of the belt body.

[0011] In this technical solution, the first air cylinder drives the glue scraping block body to approach until it abuts against the side of the belt body, and scrapes the glue liquid on the side of the belt body. The setting of the first air cylinder can scrape the side glue liquid of hook-and-loop tapes with different specifications.

[0012] In the above technical solution, further, the glue scraping block body includes a base block. One side of the base block is fixedly connected to the output end of the first air cylinder, and the other side protrudes to form an upper limit block and a lower limit block. The upper limit block and the lower limit block form a glue scraping channel for the belt body to pass through. A first inclined surface connected to the glue scraping channel is arranged on one side of the base block, and a second inclined surface connected to the first inclined surface and the glue scraping channel is arranged on the lower limit block.

[0013] In this technical solution, when the belt body passes through the glue scraping channel formed by the upper limit block and the lower limit block, the inner wall of the glue scraping channel abuts against the belt body to scrape the glue liquid on the side of the belt body. The scraped glue liquid flows down through the first inclined surface and the second inclined surface.

[0014] In the above technical solution, further, the glue scraping block body is located above the glue tank.

[0015] In this technical solution, the glue liquid scraped by the glue scraping block body can enter the glue tank and be reused, avoiding waste of the glue liquid.

[0016] In the above technical solution, further, a drying box is further included. Through openings for the tape to pass through are arranged on both sides of the drying box, and heating wires are arranged inside the drying box.

[0017] In this technical solution, by independently arranging a drying box inside the box body, the glue on the tape passing through the drying box is quickly dried. Compared with natural drying, the production cycle is greatly shortened, the production efficiency is improved, and the problems of uneven pasting or glue overflow caused by the flow of the glue are avoided, thereby ensuring the cleanliness and quality of the product.

[0018] In the above technical solution, further, a chip cleaning device is further included. The chip cleaning device includes a jet cavity arranged on the feeding side of the box body. A jet opening is arranged at the top of the jet cavity. An air guiding plate is obliquely arranged at the jet opening, and the air guiding plate faces away from the box body. The jet cavity is connected with an air inlet pipe, and the other end of the air inlet pipe is connected with a fan.

[0019] In this technical solution, the chip cleaning device is arranged to blow air towards the bottom of the tape, and the dust adhered to the side of the tape that needs to be coated with glue is blown away outside the box body, ensuring that the bottom of the tape entering the box for glue coating is relatively clean and ensuring the glue coating quality.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. A pressing component is arranged to cooperate with the glue roller to press the upper end surface of the tape, ensuring that the glue on the lower surface of the tape is evenly applied. At the same time, on the rear side of the pressing component in the tape transmission direction and on both sides of the tape, a glue scraping component is arranged, which can scrape off the overflow glue on the edge of the tape after being pressed by the pressing component. The glue application amount of the present utility model can be controlled and can be evenly applied to the bottom of the tape, and the overflow glue on the edge of the tape can be scraped off;

[0022] 2. When it is necessary to adjust the glue application amount or when it is necessary to apply glue to different thicknesses of hook-and-loop tapes, it is necessary to adjust the height of the pressing roller. Rotate the handwheel to drive the sleeve to rotate, and the first screw rod threadedly connected to the sleeve drives the connecting seat to move in the height direction in the bench. The operator can also accurately adjust the height of the pressing roller by observing the value displayed on the digital position display;

[0023] 3. By independently arranging a drying box inside the box body, the glue on the tape passing through the drying box is quickly dried. Compared with natural drying, the production cycle is greatly shortened, the production efficiency is improved, and the problems of uneven pasting or glue overflow caused by the flow of the glue are avoided, thereby ensuring the cleanliness and quality of the product;
