Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically to a tape production adhesive coating device with tension adjustment function. Background Technology

[0002] In the adhesive coating process of tape production, the tension stability of the tape substrate directly determines the coating quality. Currently, traditional adhesive coating equipment mostly uses fixed installation of the coating rollers, which cannot adaptively adjust according to real-time changes in tape tension.

[0003] When the conveyor belt experiences tension fluctuations due to uneven material, thickness deviation, or conveying speed fluctuations during the conveying process, the fixed coating roller cannot dynamically adjust its position and pressure accordingly. In addition, although some devices are equipped with tension adjustment structures, they are mostly manually adjusted. Manual adjustment is slow to respond and cannot keep up with instantaneous changes in tension. Furthermore, it relies on the operator's experience, resulting in low adjustment accuracy and reduced production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a gluing device with tension adjustment function for tape production, which has the advantage of adaptive adjustment of gluing tension.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gluing device with tension adjustment function for tape production, comprising a support frame, a conveying roller and a take-up roller rotatably mounted on the left and right sides of the inner cavity of the support frame, a drive motor fixedly mounted at the front end of the take-up roller and located on the front of the support frame, a drying chamber fixedly mounted on the left side of the conveying roller, drying components fixedly mounted on the upper and lower sides of the inner cavity of the drying chamber, vertical fixing seats fixedly mounted on the front and rear sides of the middle of the support frame, a moving groove opened inside the vertical fixing seat, a sliding block slidably mounted on the inner side of the moving groove, a gluing roller rotatably mounted between the front and rear sliding blocks, a connecting plate mounted on the top of the sliding block, an adjusting plate fixedly mounted on the outer end of the connecting plate, and support springs mounted on both sides of the bottom of the adjusting plate.

[0006] As a preferred embodiment, a bearing plate is fixedly installed at the lower end of the support spring, and the inner end of the bearing plate is connected to the outside of the support frame.

[0007] As a preferred embodiment, positioning support frames are installed on both the front and rear sides of the middle of the support frame. An adjustable screw is rotatably installed inside the upper end of the positioning support frame, and a first limiting shaft is rotatably installed at the lower end of the adjustable screw. The lower end of the first limiting shaft is in contact with the top of the adjusting plate.

[0008] As a preferred embodiment, a second limiting shaft is fixedly installed on the top of the positioning support frame, and one end of the adjustable screw passes through the second limiting shaft and is threadedly installed with the through portion therethrough.

[0009] As a preferred embodiment, the support frame is fixedly installed with legs on all four sides of its bottom, and a fastening plate is integrally installed at the lower end of the positioning support frame. The inner side of the fastening plate is attached to the outer side of the support frame and installed with bolts.

[0010] As a preferred embodiment, the inner wall of the positioning support frame is provided with an adjustment groove, and an adjustment block is installed on the side of the adjustment plate that is in contact with the inner wall of the positioning support frame, and one end of the adjustment block is slidably installed inside the adjustment groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting a sliding block to slide within the moving groove, combined with the elastic support of the adjusting plate by the support spring, allows the coating roller to adaptively move up and down according to the tension changes of the tape, thereby effectively adjusting the tension on the tape and avoiding problems such as tape breakage due to excessive tension or uneven coating due to insufficient tension. This improves the quality and stability of tape production. Utilizing the threaded connection between the adjustable screw and the second limit shaft, rotating the adjustable screw pushes the first limit shaft to apply pressure to the adjusting plate, thereby adjusting the elasticity of the support spring. This achieves flexible control of the tension adjustment range of the coating roller to adapt to the production needs of tapes of different types and thicknesses, enhancing the versatility of the device.

[0013] 2. This utility model provides a stable mounting carrier for the adjustable screw through a positioning support frame, ensuring that it will not shake or shift during the adjustment process, laying a solid foundation for subsequent precise tension adjustment. Moreover, the first limiting shaft rotatably mounted at the lower end of the adjustable screw contacts the top of the adjusting plate. When the adjustable screw rotates for adjustment, the first limiting shaft can always maintain good contact with the adjusting plate, and will not cause the adjusting plate to rotate additionally due to the rotation of the screw, ensuring the stability of the adjustment process, avoiding unnecessary interference with the position of the glue coating roller, and ensuring the stable progress of the glue coating work.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figure 1 As shown, this utility model provides a gluing device with tension adjustment function for tape production, including a support frame 1. A conveying roller 2 and a take-up roller 3 are rotatably installed on the left and right sides of the inner cavity of the support frame 1, respectively. A drive motor 4 is fixedly installed at the front end of the take-up roller 3 and on the front of the support frame 1. A drying box 5 is fixedly installed on the left side of the conveying roller 2. Drying components 16 are fixedly installed on the upper and lower sides of the inner cavity of the drying box 5. Vertical fixing seats 6 are fixedly installed on the front and rear sides of the middle of the support frame 1. A moving groove 7 is opened inside the vertical fixing seat 6. A sliding block 8 is slidably installed on the inner side of the moving groove 7. A gluing roller 9 is rotatably installed between the front and rear sliding blocks 8. A connecting plate 10 is installed on the top of the sliding block 8. An adjusting plate 13 is fixedly installed on the outer end of the connecting plate 10. Support springs 12 are installed on both sides of the bottom of the adjusting plate 13.

[0023] This technical solution uses a sliding block 8 that slides within a moving groove 7, combined with the elastic support of the adjusting plate 13 provided by the support spring 12. This allows the coating roller 9 to adaptively move up and down according to changes in the tension of the tape, effectively adjusting the tension on the tape and preventing tape breakage due to excessive tension or uneven coating due to insufficient tension. This improves the quality and stability of tape production. Furthermore, by utilizing the threaded connection between the adjustable screw 14 and the second limiting shaft 18, rotating the adjustable screw 14 pushes the first limiting shaft 17 to apply pressure to the adjusting plate 13, thereby adjusting the elasticity of the support spring 12. This enables flexible control of the tension adjustment range of the coating roller 9, adapting to the production needs of different types and thicknesses of tape and enhancing the versatility of the device.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, a support plate 11 is fixedly installed at the lower end of the support spring 12, and the inner end of the support plate 11 is connected to the outside of the support frame 1.

[0026] Adopting such Figure 1 The technical solution shown provides a stable mounting base for the support spring 12, allowing the elastic support function of the support spring 12 to be stably performed, ensuring the stability of the coating roller 9 during adaptive adjustment. The support plate 11 is connected to the support frame 1, which transmits the force of the support spring 12 to the support frame 1, dispersing the force and enhancing the load-bearing capacity of the overall structure.

[0027] Secondly, in the technical solution, positioning support frames 15 are installed on both the front and rear sides of the middle of the support frame 1. An adjustable screw 14 is rotatably installed inside the upper end of the positioning support frame 15. A first limiting shaft 17 is rotatably installed at the lower end of the adjustable screw 14. The lower end of the first limiting shaft 17 contacts the top of the adjusting plate 13. A second limiting shaft 18 is fixedly installed on the top of the positioning support frame 15. One end of the adjustable screw 14 passes through the second limiting shaft 18 and is threadedly installed with its through part.

[0028] Its adoption is as follows Figure 1 The technical solution shown provides a stable mounting carrier for the adjustable screw 14, ensuring that it will not shake or shift during adjustment, thus laying a solid foundation for subsequent precise tension adjustment. Furthermore, the first limiting shaft 17, rotatably mounted at the lower end of the adjustable screw 14, contacts the top of the adjusting plate 13. When the adjustable screw 14 rotates for adjustment, the first limiting shaft 17 maintains good contact with the adjusting plate 13 and will not cause additional rotation of the adjusting plate 13 due to the screw's rotation. This ensures the stability of the adjustment process, avoids unnecessary interference with the position of the coating roller 9, and guarantees the stable operation of the coating process.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-4 As shown, the support frame 1 has legs 19 fixedly installed around its bottom. The lower end of the positioning support frame 15 is integrally installed with a fastening plate 20. The inner side of the fastening plate 20 is attached to the outer side of the support frame 1 and installed with bolts. The inner wall of the positioning support frame 15 has an adjustment groove vertically opened. An adjustment block is installed on the side of the adjustment plate 13 that is attached to the inner wall of the positioning support frame 15, and one end of the adjustment block is slidably installed inside the adjustment groove.

[0031] Using the above technical solution, the fastening plate 20 at the lower end of the positioning support frame 15 is installed in close contact with the outside of the support frame 1 by bolts. This connection method not only allows the positioning support frame 15 to be tightly fixed with the support frame 1, ensuring that the positioning support frame 15 does not shake during operation and improving the overall structural stability, but also the bolt connection facilitates the disassembly, inspection or replacement of the positioning support frame 15 in the later stage, reducing maintenance difficulty and cost.

[0032] The adjustment groove on the inner wall of the positioning support frame 15 slides with the adjustment block on the adjustment plate 13, which plays a strict guiding role in the up and down movement of the adjustment plate 13. It can effectively limit the movement trajectory of the adjustment plate 13, prevent the adjustment plate 13 from shifting left or right or tilting during the movement, and ensure that the glue coating roller 9 always maintains the correct position when the tension is adjusted, thereby ensuring the uniformity and accuracy of glue coating.

[0033] The working principle of this utility model is as follows: The tape enters from the conveyor roller 2, passes through the coating roller 9 for coating, and then enters the drying chamber 5. Under the action of the drying component 16, the tape is dried. Finally, the winding roller 3 is wound up by the drive motor 4. When the tape tension changes, the pressure on the coating roller 9 changes, causing the sliding block 8 to slide up and down in the moving groove 7. The sliding block 8 drives the adjusting plate 13 to move up and down through the connecting plate 10, and the support spring 12 extends and retracts accordingly, realizing adaptive adjustment of tape tension to ensure uniform coating. If it is necessary to adjust the tension adjustment range, the adjustable screw 14 can be rotated to rotate and move up and down within the second limit shaft 18. The pressure on the adjusting plate 13 is changed through the first limit shaft 17, thereby adjusting the initial elastic force of the support spring 12 to adapt to different production needs.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
