Description

Technical Field

[0001] This application belongs to the field of adhesive coating technology for edge banding machine rollers, and specifically relates to an optimized structure for adhesive coating on edge banding machine rollers. Background Technology

[0002] Edge banding machine rollers refer to rollers with a rubber or other material coating used in edge banding machines. These rollers play a crucial role in the edge banding process and are widely used in printing, transportation, metallurgy, textiles, papermaking, electroplating, and many other industries. In particular, copper-plated solar cells require edge banding before electroplating to prevent the plating solution from contacting non-plating areas.

[0003] In existing technologies, due to the long-term operation of the rubber roller, the adhesive is directly exposed to the air, causing the solvent of the edge-sealing adhesive to evaporate, resulting in viscosity fluctuations. In particular, the viscosity fluctuations of the adhesive on the surface of the rubber roller are even greater. Furthermore, due to the influence of viscosity fluctuations, the flowability of the edge-sealing adhesive on the rubber roller becomes worse. Especially on the back side of the edge-sealing side, the adhesive will be unevenly distributed on the rubber roller, and there is a high risk of missing adhesive in some places. This directly affects the edge-sealing effect, resulting in missed areas and insufficient coating thickness, which in turn affects the process effect.

[0004] To address the above problems, this application designs an optimized adhesive coating structure for the glue roller of an edge banding machine, in order to solve the technical difficulties such as uneven glue distribution on the glue roller and the easy occurrence of insufficient glue in certain areas. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, this application designs an optimized adhesive coating structure for the glue roller of an edge banding machine to ensure the uniformity of glue distribution on the glue roller and prevent situations where there is insufficient glue in certain positions.

[0007] This application provides an optimized structure for applying glue to a gluing roller on an edge-wrapping machine, comprising: a metal scraper; a glue-applying roller disposed below the metal scraper; a glue-storing strip fixed to the surface of the glue-applying roller; a soft glue-scraping strip disposed between the metal scraper and the glue-applying roller; a disassembly assembly disposed between the soft glue-scraping strip and the metal scraper for convenient disassembly and replacement of the soft glue-scraping strip to be cleaned or damaged; a mounting plate disposed above the metal scraper; and a timed lifting assembly disposed below the mounting plate.

[0008] In some possible embodiments, the length of the soft scraper strip is longer than the length of the coating roller.

[0009] In some possible embodiments, the disassembly and assembly assembly includes: a magnetic iron sheet fixed to the upper end of the soft scraper strip; two insert blocks fixed to both sides of the upper end of the magnetic iron sheet, with slots on both sides of the lower end of the metal scraper, the insert blocks being inserted into the slots, and threaded holes on the front ends of the insert blocks; and two threaded locking rods threaded into the threaded holes, with the threaded locking rods threaded through the front end of the metal scraper.

[0010] In some possible embodiments, the disassembly and assembly assembly further includes: two first magnets, respectively fixed to both sides of the lower end of the metal scraper, the magnetic iron sheet being attracted to the first magnets by magnetic force; a docking block, fixed to the middle of the upper end of the magnetic iron sheet, the middle of the lower end of the metal scraper having a docking groove, the docking block docking into the docking groove; and a second magnet, fixed to the top of the docking groove.

[0011] In some possible embodiments, the docking block is made of an iron alloy, and the second magnet is attracted to the docking block by magnetic force.

[0012] In some possible embodiments, L-shaped pull blocks are fixed on both the left and right sides of the magnetic iron sheet.

[0013] In some possible embodiments, the timed lifting assembly includes: an electric cylinder fixed to the lower end of the mounting plate, and the metal scraper fixed to the power end of the electric cylinder; a timer switch and a PLC controller, both fixed to the lower end of the mounting plate, and the timer switch, the PLC controller and the electric cylinder are electrically connected.

[0014] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects: This application provides an optimized adhesive coating structure for an edge banding machine's glue roller. By setting a glue-storing strip on the surface of the glue roller, the glue-storing strip physically guides the flow of glue, ensuring that the glue accumulates on the back of the glue roller. This effectively prevents insufficient glue on the back side of the edge banding. Moreover, the glue-storing strip helps maintain the viscosity of the glue. Furthermore, a metal scraper is pressed down at regular intervals, causing the soft scraper strip to directly contact the surface of the glue roller. As the glue roller rotates, the soft scraper strip scrapes the glue on the surface of the glue roller. This method facilitates the removal of glue that has been exposed on the outer surface of the glue roller for a long time, thereby effectively ensuring the edge banding effect and preventing situations such as missed banding or insufficient banding thickness. It also helps to ensure the process effect. In addition, the inclusion of a disassembly and assembly component facilitates easy disassembly, cleaning, or replacement of damaged soft scraper strips, ensuring the normal scraping effect of the glue roller in subsequent processes.

[0018] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] The following reference Figures 1 to 7 This application describes an optimized structure for applying adhesive to a gluing roller on an edge banding machine, according to some embodiments thereof.

[0021] Please see Figures 1 to 7 The present application provides an optimized structure for applying glue to a gluing roller of an edge banding machine, comprising: a metal scraper 1; a glue-applying roller 2 disposed below the metal scraper 1; and a glue-collecting strip 3 fixed to the surface of the glue-applying roller 2.

[0022] In this embodiment, by setting a glue-storing strip 3 on the surface of the coating roller 2, the glue on the back of the coating roller 2 is ensured to accumulate through physical diversion by the glue-storing strip 3, thereby effectively ensuring that there is no lack of glue on the back side of the edge wrapping. Moreover, storing glue through the glue-storing strip 3 also helps to maintain the viscosity of the glue.

[0023] In some embodiments, a soft scraping strip 4 is disposed between a metal scraper 1 and an adhesive roller 2; a timed lifting assembly, a mounting plate 9, is disposed above the metal scraper 1; and a timed lifting assembly is disposed below the mounting plate 9; the timed lifting assembly includes: an electric cylinder 10, fixed to the lower end of the mounting plate 9, the metal scraper 1 being fixed to the power end of the electric cylinder 10; a timed switch 11 and a PLC controller 12, both fixed to the lower end of the mounting plate 9, and the timed switch 11, the PLC controller 12, and the electric cylinder 10 being electrically connected.

[0024] In this embodiment, by connecting the normally open contact (NO) of the timer switch 11 to the digital input terminal (e.g., X0) of the PLC controller 12, ensuring a correct common ground (COM terminal) connection, a circuit is formed. Then, the power supply or enable terminal of the electric cylinder 10 is driven by the output (e.g., Y0) of the PLC controller 12, thereby controlling the extension and retraction of the electric cylinder 10. Assuming the opening and closing time of the timer switch 11 is pre-set (the specific opening and closing time depends on the actual situation of removing glue from the coating roller 2), for example, if the timer switch 11 opens and closes once every hour, then the PLC controller 12 and the electric cylinder 10 can be controlled to open and close once every hour. Therefore, the timer switch 11... 1. Upon startup, the electric cylinder 10 is controlled by the PLC controller 12. The electric cylinder 10 extends and drives the metal scraper 1 and the soft scraper strip 4 downward until the soft scraper strip 4 contacts the surface of the coating roller 2. Therefore, the metal scraper 1 is pressed down at regular intervals, and the soft scraper strip 4 directly contacts the surface of the coating roller 2. With the coating roller 2 rotating, the soft scraper strip 4 scrapes the glue on the surface of the coating roller 2, and the excess glue will accumulate at the glue storage strip 3. In summary, this method facilitates the removal of glue that has been exposed on the outer surface of the coating roller 2 for a long time, thereby effectively ensuring the edge wrapping effect, preventing the occurrence of missing wrapping and insufficient wrapping thickness, and ensuring the process effect.

[0025] The length of the soft scraping strip 4 is longer than the length of the coating roller 2.

[0026] By setting the length of the soft scraper strip 4 to be longer than the length of the coating roller 2, it is beneficial to ensure the uniformity and comprehensiveness of the soft scraper strip 4 in scraping the coating roller 2 while the coating roller 2 is rotating.

[0027] In some embodiments, a disassembly and assembly assembly is provided between the soft scraper strip 4 and the metal scraper 1 for convenient disassembly and replacement of the soft scraper strip 4 to be cleaned or damaged. The disassembly and assembly assembly includes: a magnetic iron plate 5, fixed to the upper end of the soft scraper strip 4; two insert blocks 501, respectively fixed to both sides of the upper end of the magnetic iron plate 5, slots 502 are opened on both sides of the lower end of the metal scraper 1, the insert blocks 501 are inserted into the slots 502, and the front end of each insert block 501 is opened with a threaded hole 503; and two threaded locking rods 504, threadedly connected to the threaded holes 503, and the threaded locking rods 504 are threaded. The metal scraper 1 extends through the front of the metal scraper 1; the assembly and disassembly assembly also includes: two first magnets 6, which are fixed to the two sides of the lower end of the metal scraper 1 respectively, and the magnetic iron sheet 5 is attracted to the first magnets 6 by magnetic force; a docking block 7, which is fixed to the middle of the upper end of the magnetic iron sheet 5, and a docking groove 701 is opened in the middle of the lower end of the metal scraper 1, and the docking block 7 docks into the docking groove 701; a second magnet 702, which is fixed to the top of the docking groove 701; the docking block 7 is made of iron alloy, and the second magnet 702 is attracted to the docking block 7 by magnetic force; L-shaped pull blocks 8 are fixed on both sides of the magnetic iron sheet 5.

[0028] In this embodiment, by setting up a disassembly and assembly component, when the soft scraper strip 4 needs to be cleaned or is damaged and needs to be replaced, the threaded locking rod 504 is unscrewed out of the threaded hole 503, and then the magnetic iron plate 5 and the soft scraper strip 4 are pulled down by the L-shaped pull block 8. This facilitates the separation of the magnetic iron plate 5 from the first magnet 6, and also facilitates the movement of the docking block 7 out of the docking groove 701, thereby separating the docking block 7 from the second magnet 702. Therefore, it is convenient to disassemble the soft scraper strip 4 that needs to be cleaned or replaced. By inserting the insert block 501 into the slot 502 and simultaneously engaging the docking block 7 into the docking groove 701, the magnetic iron sheet 5 will be attracted to the first magnet 6 by magnetic force, and the second magnet 702 will be attracted to the docking block 7 made of iron alloy by magnetic force. Therefore, it is convenient to pre-install the new soft scraping strip 4 into the lower part of the metal scraper 1, and then tighten the threaded locking rod 504 into the threaded hole 503 to prevent the insert from separating from the slot 502 and effectively ensure the firmness of the soft scraping strip 4 after installation. In summary, it is convenient to disassemble and replace the damaged soft scraping strip 4, and to ensure the normal scraping effect of the coating roller 2.
