Description

Technical Field

[0001] This invention relates to the field of gluing machine technology, specifically to a gluing machine with a fine-tuning mechanism for guide rollers that prevent film offset. Background Technology

[0002] A laminating machine, also known as a plastic sealer, is a device that uses heat and pressure to apply adhesive film to the surface of substrates such as paper documents and photos, thereby achieving waterproof and wear-resistant protection for the substrate. It is now widely used in everyday home document protection and document lamination in office settings.

[0003] Existing small-scale glue applicators for home and office use, such as the invention patent with authorization announcement number CN206406580U, disclose a glue applicator with a limiting function, which achieves glue film limiting by setting fixed plates with movable grooves at both ends of the processing table;

[0004] The invention patent with authorization announcement number CN202053649U discloses an automatic glue-coating machine that controls glue deviation. It detects the position of the glue film by infrared photocells on both sides of the glue inlet, and then the processor controls the motor to adjust the conveying speed to achieve deviation correction.

[0005] The invention patent with authorization announcement number CN206358985U discloses a guide roller fine adjustment mechanism, which uses a screw drive to adjust the parallelism of the two ends of the guide roller to improve the problem of film material conveying deviation.

[0006] The above-mentioned patent has the following problems in actual use: When users place the adhesive film and the substrate to be glued, it is difficult to ensure that they are perfectly aligned. Initial placement deviation is easy to occur. During the conveying process, due to uneven tension on both sides and roller installation errors, the adhesive film will gradually deviate from the preset conveying track. In the end, after the glue is applied, the edge of the substrate is not completely covered by the adhesive film, and the adhesive film will wrinkle. In severe cases, it may also cause the adhesive film to get stuck on the roller, resulting in waste of the adhesive film and substrate and affecting the user experience. Summary of the Invention

[0007] The purpose of this invention is to provide a gluing machine with a fine-tuning mechanism for an anti-deviation guide roller for adhesive film, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This invention provides a gluing machine with a film anti-deviation guide roller fine-tuning mechanism, comprising a frame, a film feeding assembly installed inside the frame, a conveyor belt connected to the frame and located below the film feeding assembly, a heating gluing assembly connected between the inner walls of the left and right sides of the frame, a film wound between the heating gluing assembly and the film feeding assembly, a pressure plate fixedly connected to the frame and located inside the conveyor belt, two anti-deviation fine-tuning mechanisms symmetrically connected to the pressure plate, the film located between the two anti-deviation fine-tuning mechanisms, and a cutting assembly connected to the frame.

[0010] The anti-deviation fine-tuning mechanism includes a vertical plate fixedly connected to the upper side of the pressure plate. A threaded hole is provided on the vertical sidewall of the vertical plate, and an adjusting screw is threaded into the threaded hole. Both ends of the adjusting screw extend out of the threaded hole. A mounting plate is rotatably connected to the end of the adjusting screw near the adhesive film. Two connecting plates are symmetrically fixedly connected to the side of the mounting plate near the adhesive film. A fixed shaft is fixedly connected between the two connecting plates. A first anti-deviation guide roller is rotatably sleeved on the fixed shaft. A second anti-deviation guide roller is rotatably sleeved on each of the two connecting plates and the two mounting shafts. The two second anti-deviation guide rollers are located above and below the adhesive film, respectively. Both the first and second anti-deviation guide rollers are tightly fitted to the adhesive film. A limit mechanism is connected between the mounting plate and the vertical plate.

[0011] Furthermore, the cutting assembly includes a flexible cutting blade fixedly connected to the inner walls of the left and right sides of the frame, a blade holder fixedly connected between the inner walls of the left and right sides of the frame, the adhesive film located between the flexible cutting blade and the blade holder, and a V-shaped groove starting on the side of the blade holder closest to the flexible cutting blade.

[0012] Furthermore, the film feeding assembly includes two threaded rods symmetrically rotatably connected to the left and right sides of the frame, with locking nuts threaded onto the threaded rods, and a film roller disposed between the two locking nuts.

[0013] Furthermore, the heated gluing assembly includes a rotating shaft rotatably connected to the frame, a motor fixedly connected to the left side of the frame, the output end of the motor fixedly connected to the left end of the rotating shaft, and a self-heating gluing roller fixedly sleeved on the rotating shaft, the self-heating gluing roller being located above the conveyor belt.

[0014] Furthermore, the conveyor belt includes two sets of fixed plates fixedly connected to the frame. Each set of fixed plates is rotatably connected to a rotating shaft. A drive motor is fixedly connected to the fixed plate. The output end of the drive motor is fixedly connected to the rotating shaft. A rotating roller is rotatably sleeved on the rotating shaft. A conveyor belt is wound between the two rotating rollers.

[0015] Furthermore, the limiting mechanism includes a limiting plate fixedly connected to the mounting plate, and the vertical sidewall of the vertical plate has a limiting hole corresponding to the limiting plate, through which the limiting plate passes through the limiting hole.

[0016] Furthermore, a sleeve is fixedly fitted onto the end of the adjusting screw away from the mounting plate, and the outer wall of the sleeve has multiple anti-slip grooves evenly distributed.

[0017] Furthermore, fixing holes are provided on both the left and right sides of the frame, and the walls of the fixing holes are rounded.

[0018] Furthermore, feet are fixedly connected to the four corners of the bottom of the frame, and anti-slip pads are fixedly connected to the lower end of the feet.

[0019] Furthermore, the limiting plate is evenly provided with multiple graduated grooves, and a triangular indicator block is fixedly connected to the vertical sidewall of the vertical plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention utilizes an anti-deviation fine-tuning mechanism. When the adhesive film deviates, turning the adjusting screw causes it to move in the opposite direction of the film deviation through the threaded engagement between the screw and the threaded hole. This screw drives the first and second anti-deviation guide rollers to move. The first and second anti-deviation guide rollers work together to adjust the adhesive film, returning it to its normal position without causing damage or wrinkles. After adjustment, the first and second anti-deviation guide rollers continuously limit the movement of subsequent adhesive films, preventing further deviation. The operation is simple and convenient, allowing for quick and effective fine-tuning of the deviated adhesive film as needed. It avoids problems such as incomplete coverage of the substrate edge and wrinkles caused by adhesive film deviation during gluing, effectively improving the processing quality of the gluing machine.

[0022] 2. With the cutting component set up in this invention, when the glue coating is completed, pressing the flexible cutting blade causes it to elastically deform and move towards the blade holder. The flexible cutting blade and the V-groove work together to quickly cut the glue film, and the cut of the glue film is neat and does not affect the next glue coating. Attached Figure Description

[0032] 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.

[0033] Please see Figure 1-8This invention provides a gluing machine with a film anti-deviation guide roller fine-tuning mechanism, including a frame 1, a film feeding assembly 2 installed inside the frame 1, a conveyor belt 3 connected to the frame 1, the conveyor belt 3 being located below the film feeding assembly 2, a heating gluing assembly 4 connected between the inner walls of the left and right sides of the frame 1, a film 5 wound between the heating gluing assembly 4 and the film feeding assembly 2, a pressure plate 6 fixedly connected to the frame 1, the pressure plate 6 being located inside the conveyor belt 3, two anti-deviation fine-tuning mechanisms 7 symmetrically connected to the pressure plate 6, the film 5 being located between the two anti-deviation fine-tuning mechanisms 7, and a cutting assembly 8 connected to the frame 1.

[0034] The anti-deviation fine-tuning mechanism 7 includes a vertical plate 9 fixedly connected to the upper side of the pressure plate 6. A threaded hole 10 is provided on the vertical side wall of the vertical plate 9. An adjusting screw 11 is threaded into the threaded hole 10. Both ends of the adjusting screw 11 extend out of the threaded hole 10. A mounting plate 12 is rotatably connected to the end of the adjusting screw 11 near the adhesive film 5. Two connecting plates 13 are symmetrically fixedly connected to the side of the mounting plate 12 near the adhesive film 5. A fixed shaft 14 is fixedly connected between the two connecting plates 13. A first anti-deviation guide roller 15 is rotatably sleeved on the fixed shaft 14. A mounting shaft 16 is fixedly connected to each of the two connecting plates 13. A second anti-deviation guide roller 17 is rotatably sleeved on each of the two mounting shafts 16. The two second anti-deviation guide rollers 17 are located above and below the adhesive film 5, respectively. The first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 are both in close contact with the adhesive film 5. A limit mechanism 18 is connected between the mounting plate 12 and the vertical plate 9.

[0035] In this embodiment, when the adhesive film 5 deviates, the adjusting screw 11 is turned. Through the threaded engagement between the adjusting screw 11 and the threaded hole 10, the adjusting screw 11 moves in the opposite direction of the adhesive film 5's deviation. The adjusting screw 11 drives the first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 to move. The first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 cooperate to adjust the adhesive film 5, thereby returning the deviated adhesive film 5 to its normal position without causing damage or wrinkles. After adjustment, the first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 can continuously limit the subsequent passing adhesive film 5, thereby preventing the adhesive film 5 from deviating again. The operation is simple and convenient, and the deviated adhesive film 5 can be quickly and effectively fine-tuned according to needs. It can avoid the problem of poor adhesive quality caused by the adhesive film 5 deviating during glue application, effectively improving the processing quality of the glue application machine.

A blade holder 20 is fixedly connected between the inner walls of the left and right sides of the frame 1. The adhesive film 5 is located between the flexible cutting blade 19 and the blade holder 20. The blade holder 20 has a V-groove 21 on the side closest to the flexible cutting blade 19.

[0037] In the above embodiment, when the glue coating is completed, the flexible cutting blade 19 is pressed, and the flexible cutting blade 19 elastically deforms and moves towards the blade holder 20. The flexible cutting blade 19 and the V-groove 21 cooperate with each other to quickly cut the glue film 5, and the cut of the glue film 5 is neat and does not affect the next glue coating.

[0038] The film feeding assembly 2 includes two threaded rods 22 symmetrically rotatably connected to the left and right sides of the frame 1. Locking nuts 23 are threaded on the threaded rods 22, and a film roller 24 is arranged between the two locking nuts 23.

[0039] In this embodiment, the threaded rod 22 and the locking nut 23 cooperate with each other to enable quick disassembly and assembly of the film roller 24, thereby improving the convenience of replacing the film roller 24.

[0040] The heated gluing assembly 4 includes a rotating shaft 25 rotatably connected to the frame 1. A motor 26 is fixedly connected to the left side of the frame 1.

The self-heating gluing roller 27 is located above the conveyor belt 3.

[0041] In this embodiment, the motor 26 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the self-heating glue roller 27 to rotate. The self-heating glue roller 27 heats the glue film 5 and can squeeze the glue film 5, thereby enabling the glue film 5 to be firmly adhered to the object.

[0042] The conveyor belt 3 includes two sets of fixed plates 28 fixedly connected to the frame 1. Each set of fixed plates 28 is rotatably connected to a rotating shaft 29. A drive motor is fixedly connected to the fixed plate 28. The output end of the drive motor is fixedly connected to the rotating shaft 29. A rotating roller 30 is rotatably sleeved on the rotating shaft 29. A conveyor belt 31 is wound between the two rotating rollers 30.

[0043] In the above embodiment, the drive motor drives the rotating shaft 29 to rotate, the rotating shaft 29 drives the rotating roller 30 to rotate, the rotating roller 30 drives the conveyor belt 31 to rotate, and the conveyor belt 31 can move the piece to be glued.

[0044] The limiting mechanism 18 includes a limiting plate 32 fixedly connected to the mounting plate 12. The vertical sidewall of the vertical plate 9 has a limiting hole 33 corresponding to the limiting plate 32. The limiting plate 32 passes through the limiting hole 33 through the vertical plate 9.

[0045] In this embodiment, the limiting plate 32 and the limiting hole 33 cooperate with each other to limit the mounting plate 12, thereby preventing the mounting plate 12 from rotating with the adjusting screw 11, and thus preventing the first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 from deflecting during the adjustment process.

[0046] The end of the adjusting screw 11 away from the mounting plate 12 is fixedly fitted with a sleeve 34, and the outer wall of the sleeve 34 has a plurality of anti-slip grooves 35 evenly distributed.

[0048] Fixing holes 36 are present on both the left and right sides of the frame 1, and the walls of the fixing holes 36 are rounded.

[0049] In the above embodiment, the two fixing holes 36 are provided to facilitate the user's insertion by hand, thereby improving the user's gripping convenience when moving the equipment.

[0050] Each of the four corners of the bottom of the frame 1 is fixedly connected to a foot 37, and the lower end of the foot 37 is fixedly connected to an anti-slip pad 38.

[0051] In this embodiment, the feet 37 and the anti-slip pads 38 work together to improve the stability of the equipment placement.

[0052] The limiting plate 32 has a plurality of graduated grooves 39 evenly spaced, and the vertical sidewall of the vertical plate 9 is fixedly connected to a triangular indicator block 40.

[0053] In the above embodiment, the scale groove 39 and the triangular indicator block 40 cooperate with each other to make a more accurate reading of the adjustment stroke of the adjustment screw 11, thereby improving the adjustment accuracy.

[0054] Working principle: When the adhesive film 5 deviates, the adjusting screw 11 is turned. Through the threaded engagement between the adjusting screw 11 and the threaded hole 10, the adjusting screw 11 moves in the opposite direction of the adhesive film 5's deviation. The adjusting screw 11 drives the first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 to move. The first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 work together to adjust the adhesive film 5, thereby returning the deviated adhesive film 5 to its normal position without causing damage or wrinkles. After adjustment, the first anti-deviation guide roller 15 and the second anti-deviation guide roller 17 can continuously limit the subsequent passing adhesive film 5, thereby preventing the adhesive film 5 from deviating again. The operation is simple and convenient, and the deviated adhesive film 5 can be quickly and effectively fine-tuned according to the needs. It can avoid the problem of poor adhesive quality caused by the adhesive film 5 deviating during glue application, effectively improving the processing quality of the glue application machine.

[0055] When the gluing is completed, press the flexible cutting blade 19. The flexible cutting blade 19 elastically deforms and moves towards the blade holder 20. The flexible cutting blade 19 and the V-groove 21 work together to quickly cut the adhesive film 5, and the cut of the adhesive film 5 is neat and does not affect the next gluing.

[0056] The motor 26 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the self-heating glue roller 27 to rotate. The self-heating glue roller 27 heats the glue film 5 and can squeeze the glue film 5, so that the glue film 5 can be firmly adhered to the object.
