Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, and in particular to a tape applicator for a circular loom. Background Technology

[0002] A circular loom is an industrial weaving machine mainly used to produce tubular (tube-shaped) woven fabrics. Its core feature is that it can weave seamless cylindrical fabrics at high speed and continuously. For example, in the production of coated bulk bags, the prior art (CN102372182A) discloses that by setting an automatic tape-sticking device on the circular loom to stick the tape to the folded edge of the tubular fabric, the problem of film breakage and leakage of powdery goods at the folded edge caused by tearing off excess film edges in the subsequent coating process can be effectively solved.

[0003] However, the existing technology and current common practice rely on purchased finished tapes, which has two major drawbacks in practical applications: First, purchasing high-quality tapes to ensure adhesion leads to high production costs; second, using cheap tapes to control costs carries the risk of insufficient adhesion and easy detachment, affecting the yield rate.

[0004] Therefore, there is an urgent need in the field for a new tape application device that can reduce the cost of tape use and ensure adhesion reliability. Summary of the Invention

[0005] In order to reduce the cost of adhesive tape and ensure the reliability of adhesion when producing coated bulk bags, this application provides a tape application device for a circular loom.

[0006] The technical solution of the tape applicator for a circular loom provided in this application is as follows: A circular loom tape applicator includes a conveying mechanism for conveying products, a film roll, an adhesive applicator for applying adhesive to one side of the film, a processing mechanism for processing the adhesive-applied film, a conveying mechanism for conveying the adhesive-applied film, a guiding mechanism for guiding the adhesive-applied film to the product, and an adhesive bonding mechanism for bonding the film to the product. The adhesive applicator includes an adhesive roller for applying adhesive to the film and an adhesive applicator assembly for evenly applying adhesive to the adhesive roller. The adhesive roller is rotatably mounted on the machine base, and the film is conveyed via the adhesive roller.

[0007] By adopting the above technical solution, the adhesive roller is rotated and set on the machine base. The adhesive coating component evenly applies glue to the adhesive roller. The film material is conveyed from the film material roll to the adhesive roller, and the adhesive roller adheres the glue to the film material. The processing mechanism performs preliminary processing on the glued film material, and then the glued film material is conveyed by the conveying mechanism. The guiding mechanism guides the glued film material to the product, and the bonding mechanism bonds the film material to the product. When this device processes products with adhesive tape, it can control the adhesiveness of the tape itself without relying on purchased finished tape, thereby reducing the cost of tape use and ensuring the reliability of bonding.

[0008] Preferably, the adhesive application assembly includes a transfer roller that abuts against the adhesive roller, a transfer plate for uniformly transferring adhesive onto the transfer roller, and an adhesive coating plate for uniformly spreading the adhesive on the transfer roller. The transfer roller is rotatably mounted on the machine base, the transfer plate is positioned beside the transfer roller, and the adhesive coating plate is positioned on the transfer plate. The adhesive is uniformly adhered to the adhesive roller via the transfer roller.

[0009] By adopting the above technical solution, the transfer roller is rotated and set on the machine base, and the transfer roller abuts against the adhesive roller. The transfer plate is set next to the transfer roller, and the adhesive coating plate is set on the transfer plate. During the process of applying adhesive to one side of the film material, the transfer plate evenly transfers the adhesive to the transfer roller, the adhesive coating plate evenly spreads the adhesive on the transfer roller, and the transfer roller evenly transfers the adhesive to the adhesive roller. This facilitates the even application of adhesive to the film material and avoids the possibility of insufficient adhesive application due to uneven distribution of adhesive on the adhesive roller. It also effectively avoids the possibility of adhesive sticking to other sides of the film material.

[0010] Preferably, the conveying mechanism includes a first conveyor roller disposed on one side of the adhesive roller, a second conveyor roller disposed above the first conveyor roller, a third conveyor roller disposed on the other side of the adhesive roller, and a fourth conveyor roller disposed beside the third conveyor roller. The first, second, third, and fourth conveyor rollers are all rotatably disposed on the machine base. Each of the first, second, third, and fourth conveyor rollers is fitted with a release paper sleeve. The film material is conveyed via the first, second, third, and fourth conveyor rollers.

Release paper sleeves are fitted on conveyor roller 1, conveyor roller 2, conveyor roller 3 and conveyor roller 4. The film material is conveyed by conveyor roller 1, conveyor roller 2, conveyor roller 3 and conveyor roller 4, which facilitates the conveying of the film material after applying glue.

[0012] Preferably, the processing mechanism includes a processing component for performing preliminary shaping treatment on the coated film material and a moisturizing component for maintaining the humidity of the coated film material. The processing component and the moisturizing component are disposed on the machine base and are close to the three conveyor rollers and the four conveyor rollers.

[0013] By adopting the above technical solution, the processing component and the moisturizing component are set on the machine platform, close to conveyor roller three and conveyor roller four. During the process of conveying the film material after adhesive coating, the processing component performs preliminary shaping treatment on the film material after adhesive coating, and the moisturizing component maintains the humidity of the film material after adhesive coating. Through the processing component and the moisturizing component in treating the film material after adhesive coating, the adhesion of the film material after adhesive coating can be adjusted and controlled, ensuring the stability of the film material bonding to the product.

[0014] Preferably, the guiding mechanism includes a guide roller disposed on the machine base, an arc plate slidably disposed above the guide roller, and an adjusting block for adjusting the curvature of the film material. Multiple adjusting blocks are slidably disposed on the arc plate, and the film material is conveyed to the adjusting block via the guide roller to adjust the curvature.

[0015] By adopting the above technical solution, the guide roller is set on the machine platform, the arc plate is slidably set above the guide roller, and multiple adjusting blocks are slidably set on the arc plate. The film material is conveyed to the adjusting block via the guide roller to adjust the arc. The adjusting block adjusts the film material to an arc that is easy to bond, thereby improving the convenience of bonding between the film material and the product.

[0016] Preferably, the top surface of the arc plate is provided with an arc groove, the guide mechanism includes an arc block slidably disposed in the arc groove and a first positioning component for positioning the arc block, the adjusting block is rotatably disposed on the arc block, and the adjusting block is slidably disposed on the arc block.

[0017] By adopting the above technical solution, an arc groove is opened on the top surface of the arc plate, the arc block is slidably set in the arc groove, and the adjustment block is rotatably set on the arc block. When different specifications of products are used and different specifications of membrane materials are used, the arc block can be slidably driven to slide along the arc groove, and the adjustment block can be rotated or slid to a suitable position, which facilitates the adjustment of the curvature of membrane materials of different specifications.

[0018] Preferably, the arc plate has a sliding groove on its arc side surface, the arc block has a connecting groove on its side surface, and the connecting groove has a limiting groove on its side wall. The sliding groove, connecting groove, and limiting groove are connected to each other. The first positioning component includes a rotating rod rotatably disposed in the sliding groove, connecting groove, and limiting groove, a transition block disposed on one side of the rotating rod, and a rotating handle disposed on the other side of the rotating rod.

The adapter block is set on one side of the rotating rod and is threadedly engaged with the inner wall of the limiting groove. The rotating handle is set on the other side of the rotating rod. When it is necessary to position the arc block, the rotating handle is rotated. Under the connection of the rotating handle, rotating rod, adapter block, and arc block, the rotating handle abuts against the side of the arc plate, thereby fixing the arc block and the arc plate. After adjusting the adjustment block to the appropriate position, the position of the adjustment block can be fixed by the connection of the rotating handle, rotating rod, adapter block, and arc block, ensuring the stability of the adjustment curvature of the membrane material.

[0020] Preferably, the guiding mechanism includes a rotating block rotatably disposed on the arc block, a driving member for driving the adjusting block to slide, and a second positioning component for positioning the rotating block. The driving member is disposed on the rotating block, and the adjusting block is connected to the driving member.

[0021] By adopting the above technical solution, the rotating block is rotatably set on the arc block, the driving component is set on the rotating block, and the adjusting block is connected to the driving component. When it is necessary to adjust the angle of the adjusting block, the rotating block is rotated to drive the adjusting block to rotate. Then, the rotating block is positioned by the second positioning component, which facilitates the positioning of the angle of the adjusting block. The adjusting block is driven to slide by the driving component, which can adjust the distance between the adjusting block and the film material and the product.

[0022] Preferably, the bonding mechanism includes a slide block slidably disposed above the adjusting block, an abutment strip for abutting the film material near the product side to the product side, a front abutment roller slidably disposed on the slide block, and a rear abutment roller slidably disposed on the slide block.

The front abutment roller abuts the film material near one side of the product to one side of the product, and the rear abutment roller abuts the film material near the other side of the product to the other side of the product.

[0023] By adopting the above technical solution, the slide is slidably positioned above the adjusting block, and the abutment strip is positioned inside the slide. During the process of bonding the film material to the product, the drive slide moves the abutment strip, the front abutment roller, and the rear abutment roller closer to the film material and the product. While the abutment strip moves closer to the film material and the product, the front abutment roller pushes the film material near one side of the product to one side of the product, and the rear abutment roller pushes the film material near the other side of the product to the other side of the product. At the same time as the abutment strip abuts the film material against the side of the product, the front abutment roller bonds the film material near one side of the product to one side of the product, and the rear abutment roller bonds the film material near the other side of the product to the other side of the product, which facilitates bonding the film material to the product.

[0024] Preferably, the bonding mechanism includes a first guide strip disposed on the inner wall of one side of the slide and a second guide strip disposed on the inner wall of the other side of the slide. The film material and the product are conveyed to the front abutment roller and the rear abutment roller via the first guide strip and the second guide strip.

[0025] By adopting the above technical solution, the first guide strip is set on the inner wall of one side of the slide, and the second guide strip is set on the inner wall of the other side of the slide. The film material and the product are conveyed to the front abutting roller and the rear abutting roller after passing through the first guide strip and the second guide strip. The first guide strip and the second guide strip further reduce the curvature of the film material, so as to facilitate the front abutting roller and the rear abutting roller to bond the film material and the product together.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The adhesive roller is rotated and set on the machine base. The adhesive application component evenly applies glue to the adhesive roller. The film material is conveyed from the film material roll to the adhesive roller, and the adhesive roller adheres the glue to the film material. The processing mechanism performs preliminary processing on the glued film material. Then, the glued film material is conveyed by the conveying mechanism, the guiding mechanism guides the glued film material to the product, and the bonding mechanism bonds the film material to the product. When this device processes the product with adhesive tape, it can control the adhesiveness of the tape itself without relying on purchased finished tape, thereby reducing the cost of tape use and ensuring the reliability of bonding. 2. The transfer roller is rotated and mounted on the machine base, and the transfer roller abuts against the adhesive roller. The transfer plate is set next to the transfer roller, and the adhesive coating plate is set on the transfer plate. During the process of applying adhesive to one side of the film material, the transfer plate evenly transfers the adhesive to the transfer roller, the adhesive coating plate evenly spreads the adhesive on the transfer roller, and the transfer roller evenly transfers the adhesive to the adhesive roller. This facilitates the even application of adhesive to the film material and avoids the possibility of insufficient adhesive application due to uneven distribution of adhesive on the adhesive roller. It also effectively avoids the possibility of adhesive sticking to other sides of the film material. 3. The top surface of the arc plate is provided with an arc groove, the arc block is slidably set in the arc groove, and the adjusting block is rotatably set on the arc block. When different specifications of products are used or different specifications of membrane materials are used, the arc block can be slid to drive the adjusting block to slide along the arc groove, and the adjusting block can be rotated or slid to the appropriate position, so as to facilitate the curvature adjustment of different specifications of membrane materials.

[0062] Reference Figure 1 and Figure 6 As shown, during the process of bonding the film material to the product 1, the first cylinder 91 drives the slide 92 to slide, so that the slide 92 drives the abutment strip 93, the front abutment roller 95, and the rear abutment roller 96 to approach the film material and the product 1. The film material and the product 1 are then conveyed to the front abutment roller 95 and the rear abutment roller 96 via the first guide strip 97 and the second guide strip 98. The first guide strip 97 and the second guide strip 98 further reduce the curvature of the film material, thereby facilitating the front abutment roller 95 and the rear abutment roller 96 to bond the film material to the product 1. Reference Figure 1 and Figure 6As shown, while the abutting strip 93 approaches the film material and product 1, the second cylinder 94 drives the front abutting roller 95 to push the film material near one side of product 1 to one side of product 1. The third cylinder drives the rear abutting roller 96 to push the film material near the other side of product 1 to the other side of product 1. While the abutting strip 93 abuts the film material against the side of product 1, the front abutting roller 95 adheres the film material near one side of product 1 to one side of product 1, and the rear abutting roller 96 adheres the film material near the other side of product 1 to the other side of product 1, which facilitates the bonding of the film material to product 1.

[0063] The implementation principle of the tape applicator for a circular loom according to an embodiment of this application is as follows: The adhesive roller 51 is rotatably mounted on the machine base 3. The adhesive application component 53 evenly applies adhesive to the adhesive roller 51. The film material is conveyed from the film material roll 4 to the adhesive roller 51, and the adhesive roller 51 adheres the adhesive to the film material. The processing mechanism 6 performs preliminary processing on the adhesive-coated film material, and then the adhesive-coated film material is conveyed through the conveying mechanism 7. The guiding mechanism 8 guides the adhesive-coated film material to the product 1, and the bonding mechanism 9 bonds the film material to the product 1. When this device processes the adhesive tape on the product 1, it can control the adhesiveness of the tape itself without relying on purchased finished tape, thereby reducing the cost of tape use and ensuring the reliability of bonding.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
