Description

Technical Field

[0001] This utility model relates to the field of double-sided tape feeding technology, and in particular to a double-sided tape feeding device that prevents deviation. Background Technology

[0002] Double-sided tape is widely used in modern industrial production, indispensable in fields ranging from electronic product assembly and packaging to automotive interior manufacturing. To meet the demands of efficient and precise production, the performance requirements for double-sided tape feeding devices are increasingly stringent. Ensuring the stability and accuracy of the double-sided tape during the feeding process and preventing deviation has become a key area of ​​technological research and development in this field.

[0003] Existing double-sided tape feeding devices typically employ a simple roller conveyor structure and basic limiting devices. Their technical principle involves a motor driving a drive roller to rotate, utilizing the friction between the roller and the double-sided tape to propel the tape forward. Simultaneously, fixed limiting plates are installed on both sides of the tape, using their blocking effect to restrict the tape's position and ensure that the tape is conveyed along a predetermined path to a certain extent.

[0004] However, this traditional feeding device has significant drawbacks. Due to the elasticity of the tape itself, even a small initial offset during transmission will accumulate and amplify gradually due to the elastic deformation of the tape. Ultimately, in the winding stage, this offset results in uneven edges of the wound double-sided tape, affecting not only the product's appearance quality but also causing problems such as loose adhesion and easy detachment during subsequent use due to inconsistent tape width. This reduces production efficiency and product yield, making it difficult to meet the demands of high-precision production. Therefore, an anti-offset double-sided tape feeding device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a double-sided tape feeding device to prevent deviation, aiming to improve the problem in the prior art where a small initial deviation is amplified step by step during transmission due to the elastic deformation of the tape, eventually leading to uneven winding edges.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A double-sided tape feeding device for preventing deviation includes a bracket, a first rotating roller fixedly connected to the top of the bracket, a first support plate fixedly connected to the side wall of the bracket, a material-carrying roller rotatably connected inside the first support plate, a support platform fixedly connected to the top of the bracket, a limit post and a first adjusting post fixedly connected to the side wall of the first support plate, and a limit component provided on the outer wall of the first adjusting post. The limiting component includes a sliding plate, which is slidably connected to the outer wall of the first adjusting column. A second fixing plate is fixedly connected to the side wall of the sliding plate, and a limiting plate is fixedly connected to the side wall of the second fixing plate. The side wall of the limiting plate is slidably connected to the inside of the support platform.

[0007] As a further description of the above technical solution: The sliding plate is fixedly connected to a first ring on its side wall, and a first fixing plate is fixedly connected to the outer wall of the first ring. A fixing column is rotatably connected inside the first fixing plate.

[0008] As a further description of the above technical solution: A button is fixedly connected to one end of the fixed column, and a locking post is fixedly connected to the side wall of the button. The outer wall of the locking post is slidably connected to the inside of the first adjusting column.

[0009] As a further description of the above technical solution: The button sidewall is provided with a first spring, one end of the first spring is fixedly connected to the outer wall of the first collar, and the other end of the first spring is fixedly connected to the button sidewall.

[0010] As a further description of the above technical solution: The top of the bracket is fixedly connected to a hollow slot plate, and the hollow slot plate has multiple holes inside.

[0011] As a further description of the above technical solution: A connecting block is slidably connected inside the hollow slot plate, and a second rotating roller is rotatably connected inside the connecting block.

[0012] As a further description of the above technical solution: A second support plate is fixedly connected to the top of the connecting block, a second collar is fixedly connected inside the second support plate, a handle is slidably connected inside the second collar, and the outer wall of the handle is slidably connected inside the hole.

[0013] As a further description of the above technical solution: The second sleeve is provided with a second spring on its side wall. One end of the second spring is fixedly connected to the side wall of the second sleeve, and the other end of the second spring is fixedly connected to the outer wall of the handle.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the sliding plate slides on the outer wall of the first adjusting column and the limiting column to limit the movement. Then, the sliding plate will drive the second fixing plate and the limiting plate to slide inside the support platform, thereby achieving the effect of limiting the double-sided tape. This solves the problem that a small initial offset will be amplified step by step during the transmission process due to the elastic deformation of the tape, eventually leading to uneven winding edges, and improves the stability of the double-sided tape feeding device. 2. In this utility model, pulling the handle disengages it from the interior of the empty slot plate. Subsequently, pulling the connecting block allows it to slide against the inner wall of the empty slot plate. Simultaneously, during the process of the connecting block being subjected to force, it drives the second rotating roller inside to move up and down, thereby achieving the effect of adjusting the tension of the double-sided tape. This solves the problem that if the tension is unstable during the unwinding, transmission, and rewinding of the tape, it will cause the tape to deviate laterally, exacerbating the problem of deviation. This improves the practicality of the double-sided tape feeding device. Attached Figure Description

A second fixing plate 15 is fixedly connected to the side wall of the sliding plate 14, and a limiting plate 16 is fixedly connected to the side wall of the second fixing plate 15. The limiting plate 16 cooperates with the support platform 5 to perform lateral sliding movement, thereby achieving the effect of precisely constraining the edge deviation of the tape. The sliding plate 14 and the first adjusting column 12 form a sliding pair, and the position is locked by the elastic engagement of the locking column 10, thereby ensuring that the limiting plate 16 can adapt to the anti-deviation requirements of tapes of different widths. The side wall of the limiting plate 16 is slidably connected inside the support platform 5.

[0019] Reference Figure 1 , Figure 5 and Figure 6 A first ring 6 is fixedly connected to the side wall of the sliding plate 14. A first fixed plate 7 is fixedly connected to the outer wall of the first ring 6. A fixed column 9 is rotatably connected inside the first fixed plate 7. A button 8 is fixedly connected to one end of the fixed column 9. A locking column 10 is fixedly connected to the side wall of the button 8. The outer wall of the locking column 10 is slidably connected to the inside of the first adjusting column 12. A first spring 11 is provided on the side wall of the button 8. One end of the first spring 11 is fixedly connected to the outer wall of the first ring 6. The other end of the first spring 11 is fixedly connected to the side wall of the button 8. A slotted plate 17 is fixedly connected to the top of the bracket 1. Multiple holes 23 are opened inside the slotted plate 17. A connecting block 22 is slidably connected inside the slotted plate 17. A second rotating roller 18 is rotatably connected inside the connecting block 22. The second rotating roller 18 cooperates with the slotted plate 17 to perform vertical lifting and lowering movements. By changing the length of the tape path, the tension is dynamically adjusted. The handle 19 adopts a spring-return pin structure, which is used to quickly fix the height position of the second rotating roller 18. Its mechanical locking principle is common knowledge and will not be elaborated here. The top of the connecting block 22 is fixedly connected to the second support plate 24. The second collar 20 is fixedly connected inside the second support plate 24. The handle 19 is slidably connected inside the second collar 20. The outer wall of the handle 19 is slidably connected inside the hole 23. The side wall of the second collar 20 is provided with a second spring 21. One end of the second spring 21 is fixedly connected to the side wall of the second collar 20, and the other end of the second spring 21 is fixedly connected to the outer wall of the handle 19.

[0020] Working principle: When button 8 is pressed, the locking post 10 retracts from the inside of the first adjusting post 12, releasing the fixation of the sliding plate 14; then, the sliding plate 14 can slide along the first adjusting post 12 and the limiting post 13, driving the second fixing plate 15 and the limiting plate 16 to move inside the support platform 5, thereby precisely adjusting the distance between the limiting plate 16 and the edge of the tape. After releasing button 8, the first spring 11 pushes the locking post 10 to re-engage in the corresponding hole of the first adjusting post 12, fixing the position of the sliding plate 14. Through the continuous constraint of the limiting plate 16, the lateral displacement of the tape during transmission is effectively suppressed, avoiding the problem of displacement accumulation caused by elastic deformation. Regarding tension adjustment, pulling the handle 19 disengages it from the hole 23 of the empty slot plate 17, allowing the connecting block 22 to slide along the empty slot plate 17, driving the second rotating roller 18 to move up and down. By adjusting the height of the second rotating roller 18, the path length and tension of the tape are changed. After releasing the handle 19, the second spring 21 resets it and engages it with the target hole 23, fixing the position of the connecting block 22. This ensures that the tension of the tape is stable during unwinding, transmission, and rewinding, further reducing the risk of lateral deviation caused by uneven tension, thereby improving feeding accuracy and rewinding neatness.
