A kind of gluing device for cloth base adhesive tape production

Abstract

This invention discloses a coating device for producing cloth-based adhesive tape, belonging to the technical field of coating equipment. It includes a mounting base, with a first mounting frame and a second mounting frame sequentially connected to the top of the mounting base along the feeding direction. A lower conveying roller and an upper conveying roller, symmetrically arranged for conveying the substrate, are rotatably connected within the first mounting frame, forming a conveying channel between them. When a thick substrate passes through, the upper conveying roller is pushed upwards along the first mounting frame, and the diverting frame is simultaneously raised via a connecting plate and connecting strip, preventing the dispensing tube from scratching the substrate and causing localized glue accumulation. Simultaneously, the connecting strip drives the transmission rack to mesh with the driven gear, which in turn drives the threaded rod to rotate via a synchronous pulley and synchronous belt. This causes the circular structure formed by the arc-shaped block to shrink, slowing down the rotation speed of the mixing frame, thickening the adhesive, and fully filling the pores of the thick substrate to improve adhesion. When a thin substrate passes through, the upper conveying roller falls back, causing the diverting frame to descend, preventing glue splashing and ensuring a uniform adhesive layer.

Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment technology, specifically to an adhesive coating device for the production of cloth-based adhesive tape. Background Technology

[0002] Adhesive tape is a common household item used for bonding, packaging, and more. It's made by coating one side of a thin film with glue, then cutting it into smaller rolls – the adhesive tape we use daily. The production of adhesive tape requires specialized adhesive coating equipment for transparent tape manufacturing.

[0003] An existing patent (publication number: CN111299076A) discloses a coating equipment for transparent tape production. Addressing the problem of protrusions easily caused by coating equipment, the following solution is proposed: Two support plates are included. A common glue spraying mechanism is located near the top of the outer wall of one side of the two support plates. An unwinding mechanism is located on one side of the outer wall of each support plate. A second roller is inserted into the outer wall of one side of the two support plates, located directly below the glue spraying mechanism. A winding mechanism is located on one side of the outer wall of each support plate. A tilted steel plate is bolted to the outer wall of one side of the opposite side of the two support plates. An integrated displacement sensor is bolted to one side of the top outer wall of the steel plate. This invention uses the integrated displacement sensor to determine whether there are protrusions on the surface of the coated film. If protrusions are found, a scraper motor is activated, causing the screw to rotate and drive the scraper to perform a back-and-forth scraping process, flattening the protrusions and eliminating them.

[0004] During operation, the aforementioned adhesive coating equipment sprays adhesive downwards through multiple coating tubes to achieve the desired coating effect. However, the device cannot adjust the viscosity of the adhesive and the coating height according to the thickness of the substrate. Consequently, the coating height cannot be adapted to substrates of different thicknesses, which may result in thick substrates being easily scratched or deformed by the coating tubes; thin substrates may experience adhesive splattering and uneven adhesive layers due to excessive spacing. Furthermore, the inability to synchronously adjust the viscosity of the adhesive during coating can lead to insufficient adhesion on thick substrates due to the adhesive being too thin to fill pores; and on thin substrates, the adhesive layer may harden and become entangled and stuck together due to the adhesive being too thick.

[0005] To address these issues, we designed a coating device for producing cloth-based adhesive tapes. Summary of the Invention

[0006] The purpose of this invention is to provide a coating apparatus for the production of cloth-based adhesive tape, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a coating device for producing cloth-based adhesive tape, comprising a mounting base, wherein a first mounting frame and a second mounting frame are sequentially connected to the top of the mounting base along the feeding direction; a lower conveying roller and an upper conveying roller symmetrically connected for conveying substrate are rotatably connected in the first mounting frame, forming a conveying channel between the lower and upper conveying rollers; a diverting frame that can slide vertically along the height of the second mounting frame is provided in the second mounting frame; one end of the upper conveying roller and the diverting frame extends to the outside of the first and second mounting frames respectively and is connected to a connecting plate; a connecting strip connects the two connecting plates; a glue storage tank is connected to the top of the second mounting frame; a stirring frame is rotatably connected in the glue storage tank; a servo motor for driving the stirring frame to rotate is provided in the second mounting frame; a speed regulating component is provided between the stirring frame and the servo motor for adjusting the speed of the stirring frame; and a linkage component is provided between the connecting strip and the speed regulating component.

[0008] Furthermore, the speed regulating component includes a rotating disk rotatably connected to one side of the second mounting bracket and driven by a servo motor. Multiple connecting columns are radially slidably connected within the rotating disk. These connecting columns are arranged in a circumferential array with equal spacing around the center of the rotating disk. One end of each connecting column extends to the outside of the rotating disk and is connected to an arc-shaped block. The multiple arc-shaped blocks cooperate to form a circular ring structure. A first synchronous pulley is rotatably connected to one side of the glue storage tank. The first synchronous pulley and the stirring frame are coaxially arranged. A first synchronous belt drives the circular ring structure and the first synchronous pulley. A driving component for driving the connecting columns to slide is slidably disposed within the rotating disk.

[0009] Furthermore, the driving component includes a cylinder connected to one side of the rotating disk, a threaded rod rotatably connected inside the cylinder, a threaded cylinder threadedly connected to the threaded rod, a connecting rod connected to the bottom of the threaded cylinder, a first partition connecting the second mounting bracket and the glue storage tank, one end of the connecting rod extending into the first partition and connected to a limiting block, the limiting block being slidably connected inside the first partition.

[0010] Furthermore, the bottom of the threaded cylinder is rounded, and a ball bearing is rotatably connected to the end of the connecting post away from the arc-shaped block.

[0011] Furthermore, the linkage includes a third synchronous pulley coaxially connected to the threaded rod, a transmission rack connected to the bottom of the connecting bar, a driven gear meshing with one side of the transmission rack, a second synchronous pulley coaxially disposed on the driven gear, and a second synchronous belt drivingly connecting the second synchronous pulley and the third synchronous pulley.

[0012] Furthermore, a second partition is connected between the first mounting bracket and the second mounting bracket, and a fixed seat is connected to the second partition. A telescopic rod is slidably connected to the fixed seat. One end of the telescopic rod is connected to a limiting tooth block for limiting the driven gear. A return spring is sleeved on the telescopic rod. One end of the return spring is connected to the limiting tooth block, and the other end is connected to the fixed seat.

[0013] Furthermore, a third mounting bracket is connected to the top of the mounting base, a placement frame is slidably disposed on the third mounting bracket, a reciprocating screw is rotatably connected inside the placement frame, a transmission nut is threaded onto the reciprocating screw, and a scraper is connected to one side of the transmission nut.

[0014] Furthermore, a telescopic cylinder is connected to the third mounting bracket, and the drive end of the telescopic cylinder is connected to the placement frame.

[0015] Furthermore, a guide rod is connected inside the placement frame, and the transmission nut is slidably connected to the guide rod.

[0016] Furthermore, the top of the mounting base is connected to a tension roller and a receiving roller connected sequentially along the feeding direction, with the tension roller located on one side of the third mounting frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When a thick substrate passes through, the upper conveyor roller is pushed upward along the first mounting frame. This, along with the connecting plate and connecting strip, causes the distribution frame to rise synchronously, preventing the glue outlet tube from scratching the substrate and causing localized glue accumulation. Simultaneously, the connecting strip drives the transmission rack to mesh with the driven gear, which in turn drives the threaded rod to rotate via the synchronous pulley and synchronous belt. This causes the circular structure formed by the arc-shaped blocks to shrink, slowing the rotation speed of the mixing frame and thickening the glue, thus fully filling the pores of the thick substrate and improving adhesion. When a thin substrate passes through, the upper conveyor roller falls back, causing the distribution frame to descend, preventing glue splashing and ensuring a uniform glue layer.

[0018] 2. The reset spring pushes the limit tooth block to lock the driven gear, preventing the adjustment parameters from deviating due to equipment vibration or glue resistance, and ensuring the consistency of product quality across different batches; the telescopic cylinder precisely adjusts the scraper spacing, and the reciprocating screw drives the scraper to smoothly scrape the glue along the guide rod, effectively flattening the glue layer protrusions and solving the problem of uneven glue layer.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 3This invention provides a technical solution: a coating device for producing cloth-based adhesive tape, comprising a mounting base 1, with a first mounting frame 2 and a second mounting frame 5 sequentially connected to the top of the mounting base 1 along the feeding direction. The first mounting frame 2 has a lower conveying roller 3 and an upper conveying roller 4 symmetrically connected for conveying the substrate, forming a conveying channel between them. The second mounting frame 5 has a diversion frame 6 that can slide vertically along its height. One end of the upper conveying roller 4 and the diversion frame 6 extends to the outside of the first and second mounting frames 2 and is connected to a connecting plate 7, respectively. A connecting strip 8 connects the two connecting plates 7. A glue storage tank 11 is connected to the top of the second mounting frame 5, with a stirring frame 12 rotatably connected inside. The second mounting frame 5 has a servo motor 13 for driving the stirring frame 12 to rotate. The stirring frame 12 and the servo motor 13 are equipped with speed regulating components for adjusting the rotational speed of the stirring frame 12. A linkage component is provided between the connecting strip 8 and the speed regulating components.

[0023] In specific implementation, when the substrate passes through the conveying channel formed by the lower conveying roller 3 and the upper conveying roller 4, the thick substrate pushes the upper conveying roller 4 to rise and fall vertically along the first mounting frame 2; the upper conveying roller 4 is linked with the diverting frame 6 through the connecting plate 7, the connecting strip 8, and the diverting frame 6 to rise and fall synchronously along the second mounting frame 5, so as to realize the real-time adaptation of the coating height and the substrate thickness; the servo motor 13 drives the mixing frame 12 to rotate and stir the glue; the speed regulating component can change the speed of the mixing frame 12; the connecting strip 8 transmits the adjustment result of the coating height to the speed regulating component through the linkage component, so as to realize the synchronous linkage adjustment of the substrate thickness, coating height and viscosity.

[0024] See Figure 8 and Figure 9 The speed regulating component includes a rotating disk 14 rotatably connected to one side of the second mounting bracket 5 and driven by a servo motor 13. Multiple connecting posts 15 are radially slidably connected inside the rotating disk 14. The multiple connecting posts 15 are distributed in a circumferential array with the center of the rotating disk 14 as the center and are evenly spaced. One end of the connecting post 15 extends to the outside of the rotating disk 14 and is connected to an arc-shaped block 16. The multiple arc-shaped blocks 16 cooperate to form a ring structure. A first synchronous wheel 17 is rotatably connected to one side of the glue storage tank 11. The first synchronous wheel 17 and the stirring rack 12 are coaxially arranged. A first synchronous belt 18 is connected between the ring structure and the first synchronous wheel 17. A driving component for driving the connecting posts 15 to slide is slidably arranged inside the rotating disk 14.

[0025] In practice, the servo motor 13 drives the rotating disk 14 to rotate, and multiple connecting columns 15 slide radially along the rotating disk 14, causing the arc-shaped blocks 16 to extend and retract synchronously, thus expanding or shrinking the diameter of the annular structure formed by the multiple arc-shaped blocks 16. The annular structure is driven by the first synchronous belt 18 and the first synchronous pulley 17. Since the first synchronous pulley 17 is coaxial with the stirring rack 12, the change in the diameter of the annular structure will change the transmission ratio: the larger the diameter of the annular structure, the higher the linear speed transmitted by the first synchronous belt, and the faster the rotation speed of the stirring rack 12; conversely, the smaller the diameter, the slower the rotation speed. This setting can adapt to different viscosity requirements and ensure the bonding performance of thick and thin substrates.

[0026] See Figure 9 The driving component includes a cylinder connected to one side of the rotating disk 14, a threaded rod 19 rotatably connected inside the cylinder, a threaded cylinder 20 threadedly connected to the threaded rod 19, a connecting rod 22 connected to the bottom of the threaded cylinder 20, a first partition connecting the second mounting bracket 5 and the glue storage box 11, one end of the connecting rod 22 extending into the first partition and connected to a limiting block 23, and the limiting block 23 slidably connected inside the first partition.

[0027] In practice, the threaded rod 19 rotates inside the cylinder on one side of the rotating disk 14, causing the threaded cylinder 20 to move axially. The threaded cylinder 20 is connected to the limiting block 23 through the connecting rod 22. The limiting block 23 slides inside the first partition, restricting the rotation of the threaded cylinder 20 and ensuring that it only moves axially. Then, the connecting column 15 is driven to slide radially through the inclined plane extrusion.

[0028] See Figure 9 The bottom of the threaded cylinder 20 is rounded, and the end of the connecting column 15 away from the arc block 16 is rotatably connected to a ball bearing 21.

[0029] In practice, the rounded corner at the bottom of the threaded cylinder 20 makes rolling contact with the ball 21 at the end of the connecting column 15, converting sliding friction into rolling friction, reducing resistance during the adjustment process, and allowing the threaded cylinder 20 to slide only axially.

[0030] See Figure 6 and Figure 7 The linkage includes a third synchronous pulley 25 coaxially connected to the threaded rod 19, a transmission rack 9 connected to the bottom of the connecting bar 8, a driven gear 10 meshing with one side of the transmission rack 9, a second synchronous pulley 24 coaxially arranged on the driven gear 10, and a second synchronous belt 26 drivingly connecting the second synchronous pulley 24 and the third synchronous pulley 25.

[0031] In practice, the upper conveyor roller 4 lifts and lowers, causing the connecting bar 8 to move synchronously. The transmission rack 9 at the bottom of the connecting bar 8 meshes with the driven gear 10, causing the driven gear 10 to rotate. The driven gear 10 drives the third synchronous wheel 25 to rotate through the coaxial second synchronous wheel 24 and second synchronous belt 26. Since the third synchronous wheel 25 is coaxial with the threaded rod 19, it drives the threaded rod 19 to rotate, triggering the speed regulating component to adjust the rotation of the stirring frame 12.

[0032] See Figure 7 A second partition is connected between the first mounting bracket 2 and the second mounting bracket 5. A fixed seat 27 is connected to the second partition. A telescopic rod 28 is slidably connected to the fixed seat 27. One end of the telescopic rod 28 is connected to a limiting tooth block 29 for limiting the driven gear 10. A return spring 30 is sleeved on the telescopic rod 28. One end of the return spring 30 is connected to the limiting tooth block 29, and the other end is connected to the fixed seat 27.

[0033] In practice, the reset spring 30 pushes the limiting tooth block 29 on the telescopic rod 28 to mesh with the driven gear 10, restricting the reverse rotation of the driven gear 10 and improving the stability of the adjustment.

[0034] See Figure 10 The top of the mounting base 1 is connected to a third mounting bracket 31. A placement frame is slidably mounted on the third mounting bracket 31. A reciprocating screw 32 is rotatably connected inside the placement frame. A transmission nut 33 is threaded onto the reciprocating screw 32. A scraper 35 is connected to one side of the transmission nut 33.

[0035] In practice, the reciprocating screw 32 inside the third mounting bracket 31 rotates, driving the transmission nut 33 to move back and forth along the screw, thereby driving the scraper 35 to scrape the surface of the substrate after applying the adhesive back and forth, flattening the raised adhesive layer.

[0036] See Figure 10 A telescopic cylinder 34 is connected to the third mounting bracket 31, and the drive end of the telescopic cylinder 34 is connected to the placement frame.

[0037] In practice, the telescopic cylinder 34 drives the placement frame to rise and fall, adjusting the distance between the scraper 35 and the substrate surface to ensure that the scraper 35 is always in contact with the adhesive layer surface, adapting to the adhesive scraping requirements of substrates with different thicknesses.

[0038] See Figure 10 A guide rod 36 is connected inside the placement frame, and a transmission nut 33 is slidably connected to the guide rod 36.

[0039] In practice, this setting ensures that the transmission nut 33 moves back and forth only along the guide rod 36 in a straight line, driving the scraper 35 to scrape the glue smoothly.

[0040] See Figures 1 to 4The top of the mounting base 1 is connected to a tension roller and a receiving roller connected in sequence along the feeding direction, with the tension roller located on one side of the third mounting frame 31.

[0041] In practice, the tensioning roller pre-tensions the substrate to ensure that it remains flat during the application and scraping of adhesive; the take-up roller winds up the finished substrate.

[0042] Working principle: Before use, all electrical appliances inside and outside this device need to be connected to an external power source, or a battery pack needs to be installed in an area outside this device that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0043] In use, when substrates of different thicknesses pass through the conveying channel, the upper conveying roller 4 is pushed vertically upward along the first mounting frame 2. For thin substrates, the upper conveying roller 4 is pushed downward. Since one end of the upper conveying roller 4 and the diverting frame 6 extends to the outside of the mounting frame and is rigidly connected by the connecting plate 7 and the connecting strip 8, the lifting and lowering action of the upper conveying roller 4 will synchronously drive the diverting frame 6 to slide vertically along the height direction of the second mounting frame 5. This allows for real-time adjustment of the distance between the glue outlet at the bottom of the diverting frame 6 and the surface of the substrate. This increases the glue application height for thick substrates, preventing the glue outlet tube from scratching or deforming the substrate. Conversely, it decreases the glue application height for thin substrates, preventing glue splashing and uneven glue layer. While the adhesive application height is adjusted, the connecting strip 8 moves synchronously with the upper conveyor roller 4 as it rises and falls. The transmission rack 9 at its bottom meshes with the driven gear 10 and drives it to rotate. The driven gear 10 drives the third synchronous wheel 25 to rotate through the second synchronous wheel 24 and the second synchronous belt 26, which are coaxially arranged. The third synchronous wheel 25 is coaxially connected to the threaded rod 19 of the driving component, thereby driving the threaded rod 19 to rotate in the cylinder on one side of the rotating disk 14. When the threaded rod 19 rotates, the threaded cylinder 20 connected by the thread is restricted by the connecting rod 22 and the limiting block 23, and only moves up and down in the axial direction. The rounded corner at the bottom of the threaded cylinder 20 forms rolling contact with the ball 21 at the end of the connecting column 15. The inclined surface extrusion drives multiple connecting columns 15 to slide radially along the rotating disk 14. The sliding of the connecting column 15 drives the arc-shaped block 16 to extend and retract synchronously, causing the diameter of the ring structure formed by the cooperation of multiple arc-shaped blocks 16 to change. The ring structure is driven by the first synchronous belt 18 and the first synchronous pulley 17. Since the first synchronous pulley 17 is coaxial with the stirring frame 12, the change in the ring diameter will change the transmission ratio. At this time, the larger the ring diameter, the higher the linear speed transmitted by the first synchronous belt, the faster the rotation speed of the stirring frame 12, the greater the shear force of the glue, and the lower the viscosity. The smaller the ring diameter, the slower the rotation speed of the stirring frame 12, the smaller the shear force of the glue, and the higher the viscosity. This achieves the requirement of adapting to high viscosity glue for thick substrates and adapting to low viscosity glue for thin substrates, solving the problems of insufficient adhesion of thick substrates and hardening of the glue layer on thin substrates. After adjustment, the reset spring 30 pushes the limit tooth block 29 on the telescopic rod 28 to mesh with the driven gear 10, restricting the driven gear 10 from rotating in the opposite direction due to equipment vibration or glue resistance; After the adhesive in the storage tank 11 is stirred and adjusted to a suitable viscosity by the mixing rack 12, it flows into the distribution frame 6 and is evenly coated onto the substrate surface through the bottom dispensing pipe. The coated substrate continues to be conveyed forward to the third mounting frame 31. The telescopic cylinder 34 drives the placement frame to rise and fall, adjusting the distance between the scraper 35 and the substrate surface to ensure that the scraper 35 is always in contact with the adhesive layer. Subsequently, the reciprocating screw 32 in the placement frame rotates, driving the transmission nut 33 to move back and forth linearly along the guide rod 36, thereby driving the scraper 35 to scrape the adhesive layer on the substrate surface back and forth, smoothing out the raised adhesive layer.
