Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0042] Reference Figures 1 to 5 This utility model proposes an adhesive tape applicator, comprising:

[0043] Mounting bracket 1;

[0044] The tape supply mechanism 2 is mounted on the mounting frame 1 and is used to store and supply tape.

[0045] The tape cutting mechanism 3 is located at the discharge end 21 of the tape supply mechanism 2 and is used to cut the tape.

[0046] The tape application mechanism 4 is rotatably mounted on the mounting frame 1. The tape application mechanism 4 includes a clamping member 41 for clamping or releasing the tape, and a pressing member 42 that moves vertically to achieve tape application. The clamping member 41 is provided corresponding to the discharge end 21, and the pressing member 42 is provided between the discharge end 21 and the clamping member 41.

[0047] The first driving component 5 is used to drive the tape applicator 4 to rotate relative to the mounting frame 1, so that the clamping component 41 moves closer to or further away from the discharge end 21, thereby enabling the clamping component 41 to clamp or pull out the tape.

[0048] In this embodiment, the mounting frame 1 serves as a supporting body, supporting various functional components and providing a stable structural foundation; the tape supply mechanism 2 is mounted on the mounting frame 1, storing and continuously supplying tape to ensure a stable and smooth tape output process; the tape cutting mechanism 3 is located at the discharge end 21 of the tape supply mechanism 2, cutting the output tape to facilitate subsequent bonding operations; the tape bonding mechanism 4 is rotatably mounted on the mounting frame 1, including a clamping member 41 and a pressing member 42. The clamping member 41 is used to clamp and release the tape, while the pressing member 42 is used to apply and press the tape vertically.

[0049] Specifically, the clamping member 41 is disposed at one end of the tape applicator 4, corresponding to the discharge end 21; the pressing member 42 is disposed between the clamping member 41 and the discharge end 21, and is used to press the tape onto the surface of the target object after the tape applicator 4 completes the pulling action.

[0050] The first driving component 5 is connected between the tape applicator 4 and the mounting frame 1, and is used to drive the tape applicator 4 to rotate around a preset axis. When the tape applicator 4 rotates, the clamping component 41 can approach the discharge end 21 and clamp the tape, while the pressing component 42 avoids the position of the discharge end 21 due to its structural arrangement, so as to avoid interfering with the tape supply path during the clamping process. After clamping is completed, the first driving component 5 drives the tape applicator 4 to rotate in the opposite direction, so that the clamping component 41 pulls the tape out from the supply end, and the pressing component 42 rotates back to its original position with the tape applicator 4. At this time, the pressing component 42 is exactly above the tape output path, and then the pressing component 42 presses down to press the pulled-out tape onto the surface of the packaging bag, completing a complete automatic tape applicator operation.

[0051] This structure achieves spatial coordination and motion decoupling between tape clamping, pulling out, and pressing by rotating the tape applicator 4 as a whole, effectively improving tape applicator efficiency and stability. Compared with the existing method of relying on manual tape applicator, the tape applicator in this embodiment has higher bonding efficiency, significantly improves the automation level of the packaging production line and the consistency of finished products, and has good automation adaptability and application prospects.

[0052] Furthermore, the tape supply mechanism 2, the tape cutting mechanism 3, and the tape application mechanism 4 form a tape application execution unit; multiple tape application execution units are arranged sequentially along the length of the mounting frame 1. In this embodiment, integrating the three functional structural modules of tape supply, cutting, and application into a single tape application execution unit facilitates modular design and makes the assembly, debugging, and maintenance of the device easier. By setting multiple tape application execution units on the mounting frame 1, multiple tapes can be applied simultaneously, adapting to parallel operations of multiple rows of packaging bags or the packaging needs of different bags, thereby improving production efficiency.

[0053] Furthermore, each tape application unit also includes a first bracket 6 and a second bracket 7 connected to each other; the tape supply mechanism 2 and the tape cutting mechanism 3 are disposed on the first bracket 6; and the tape application mechanism 4 is disposed on the second bracket 7.

[0054] The first bracket 6 and the second bracket 7 are both slidably mounted on the mounting frame 1; the mounting frame 1 includes a first guide rod 11 for guiding the first bracket 6 to slide, and a second guide rod 12 for guiding the second bracket 7 to slide.

[0055] Reference Figure 1 and Figure 5In this embodiment, to enhance the independence and flexibility of the various structures within the adhesive application unit, the device is divided into two structural carriers: a first bracket 6 and a second bracket 7. The first bracket 6 is connected to the second bracket 7 via a snap-fit ​​part 64. The first bracket 6 and the second bracket 7 can move synchronously while respectively supporting different structural modules, facilitating module management and adjustment. By providing a first guide rod 11 and a second guide rod 12, both brackets can slide on the mounting frame 1, allowing for fine-tuning of the adhesive application position or tape path during equipment adjustments, thus improving application accuracy and adaptability.

[0056] Furthermore, the second guide rod 12 is rotatably connected to the mounting bracket 1, and a connector 121 is provided on the second guide rod 12;

[0057] The first driving component 5 is mounted on the mounting frame 1. The driving end of the first driving component 5 is connected to the connecting component 121 to drive the second bracket 7 to rotate around the second guide rod 12, thereby realizing the rotation of the tape applicator 4 relative to the mounting frame 1.

[0058] Reference Figure 1 To achieve coordinated spatial movement of the tape-applying mechanism 4, the second guide rod 12 is rotatably connected to the mounting bracket 1 and is connected to the first drive member 5 via a connector 121, allowing the movement of the first drive member 5 to be transmitted to the second bracket 7 via the connector 121. In this embodiment, multiple tape-applying mechanisms 4 are provided on the second guide rod 12. To ensure rotational stability, there are two first drive members 5 and two connectors 121, respectively located at both ends of the second guide rod 12.

[0059] The core of this structural design lies in rotating the second bracket 7 as a whole to drive the tape-applying mechanism 4 to rotate around the second guide rod 12. This achieves misalignment and avoidance of the pressing component 42 while allowing the clamping component 41 to smoothly approach the discharge end 21 and clamp the tape. After the tape-applying mechanism 4 completes clamping, the first drive component 5 reverses its action, causing the tape-applying mechanism 4 to rotate back to its original position and pull out the tape. After the pressing component 42 returns to its aligned position, it then presses the tape onto the surface. This structure effectively improves the spatial adaptability and automation control precision during the tape-applying process, making it particularly suitable for the precise control requirements of multi-stage collaborative operation scenarios.

[0060] Furthermore, it also includes a tape adsorption mechanism 8, which includes a plurality of adsorption holes disposed on the lower surface of the pressing member 42, a vacuum pipe 81 disposed on the pressing member 42, and a vacuum generator 82 connected to the vacuum pipe 81. The vacuum pipe 81 is used to connect the adsorption holes and the vacuum generator 82 to achieve adsorption of the tape.

[0061] To prevent the tape from shifting during operation, this embodiment includes a tape adsorption mechanism 8 on the pressing member 42 for temporarily positioning the tape before bonding. Specifically, the lower surface of the pressing member 42 has several adsorption holes (not shown in the figure). These holes are connected to the vacuum generator 82 above through vacuum pipes 81 arranged inside the pressing member 42, forming a negative pressure suction to ensure that the tape maintains a stable bonding posture during bonding. This structure significantly improves bonding accuracy and prevents the tape from wrinkling or shifting.

[0062] In this embodiment, the adsorption hole is directly set on the lower surface of the pressing member 42 and integrated with the action component of the adhesive tape into a single structure. This structure has a high degree of integration, eliminates the need for a separate adsorption module, simplifies the overall structure, reduces the number of components, and allows the adsorption and pressing actions to be seamlessly connected, which helps to improve the bonding efficiency and accuracy.

[0063] Reference Figure 1 , Figure 2 and Figure 5 This embodiment only shows a portion of the vacuum pipe 81. In actual use, the other parts of the vacuum pipe 81 connecting the adsorption hole and the vacuum generator 82 are made of detachable hoses.

[0064] Furthermore, the clamping member 41 includes a movable part 411 and a fixed part 412 arranged opposite to each other; the fixed part 412 is provided with a first guide slope 4111 on the side facing the discharge end 21; the lower end of the movable part 411 is provided with a second guide slope 4121, and the second guide slope 4121 is arranged opposite to the first guide slope 4111.

[0065] Reference Figure 3 To improve the smoothness and positioning accuracy of the clamping action, the clamping component 41 in this embodiment adopts a one-moving-one-stationary cooperation structure, namely, it consists of a fixed part 412 and a movable part 411. The fixed part 412 is fixedly installed below the second bracket 7, and a first guide slope 4111 is provided on the side facing the discharge end 21, which serves as a guide structure to guide the tape into the clamping position. The movable part 411 is located directly above the fixed part 412, and a second guide slope 4121 is provided at its lower end, which aligns with the first guide slope 4111. When the movable part 411 moves downward under the drive, the two guide slopes form a tight fit, which not only facilitates automatic centering, but also allows for smooth contact with the tape during the clamping process, preventing impact and damage.

[0066] Furthermore, both the clamping member 41 and the pressing member 42 are located at the lower end of the second bracket 7;

[0067] The second bracket 7 is also provided with a second drive member 71 for driving the lowering member 42 to rise and fall, and a third drive member 72 for driving the moving part 411 to rise and fall.

[0068] Reference Figure 2To achieve precise gripping and application of the adhesive tape, in this embodiment, the clamping component 41 and the pressing component 42 are both located at the lower end of the second bracket 7, facilitating a compact overall structural layout and coordinated operation. The pressing component 42 is driven to rise and fall by the second driving component 71 to perform the final application action; the movable part 411 is driven to rise and fall by the third driving component 72 to grip and release the adhesive tape. The two driving components are independent of each other, supporting both sequential actions and coordinated or delayed execution through a control program, ensuring flexible adjustment and efficient execution of the adhesive application chain. This design helps reduce interference between mechanisms, improves equipment stability, and facilitates subsequent structural expansion or replacement.

[0069] Furthermore, the first bracket 6 is mounted on the first guide rod 11 via a limiting ring 61; the limiting ring 61 is sleeved on the outside of the first guide rod 11, and a limiting rod 62 is radially mounted on the limiting ring 61; the first bracket 6 is also provided with an elastic element 63, which is used to push the limiting rod 62 through the limiting ring 61 and abut against the first guide rod 11.

[0070] To achieve rapid positioning and stable limiting of the first bracket 6 on the first guide rod 11, this embodiment provides a limiting ring 61 sleeved on the outside of the first guide rod 11, and a limiting rod 62 passing through the limiting ring 61. In conjunction with the elastic element 63 on the first bracket 6, the limiting rod 62 is always pressed towards the first guide rod 11 when not in operation, thus achieving automatic locking of the bracket. In this embodiment, the elastic element 63 is a compression spring. When it is necessary to adjust the position of the first bracket 6 on the first guide rod 11, it can be released by pulling out the limiting rod 62, giving the first bracket 6 good adjustability and stability.

[0071] Furthermore, the tape cutting mechanism 3 includes a connecting rod 31, a fourth driving member 32, and a cutting blade 33; one end of the connecting rod 31 is rotatably mounted on the first bracket 6, and the other end is provided with the cutting blade 33; the driving end of the fourth driving member 32 is connected to the middle of the connecting rod 31, and is used to drive the connecting rod 31 to rotate around the axis so that the cutting blade 33 extends into or exits the gap between the discharge end 21 and the lower pressing member 42.

[0072] This embodiment employs a swing-arm cutting structure driven by a connecting rod 31. One end of the connecting rod 31 is fixed as a rotating axis, and the other end is fitted with a cutting blade 33. A fourth driving component 32 acts on the middle of the connecting rod 31. When the fourth driving component 32 is activated, it causes the connecting rod 31 to swing around the axis, allowing the cutting blade 33 to switch between a cutting position and an avoidance position, effectively preventing interference with other components during the adhesive application process.

[0073] Furthermore, the tape supply mechanism 2 includes a tape mounting seat 22 for mounting the tape, a traction roller assembly 23 for pulling the tape, and a pressure plate 24 for preventing tape deviation, the pressure plate 24 being disposed on the side of the discharge end 21 away from the cutting blade 33.

[0074] To ensure a smooth and orderly tape supply process, the tape supply mechanism 2 is equipped with a tape mounting base 22, a traction roller assembly 23, and a tape pressure plate 24. The tape mounting base 22 is used to accommodate and fix the tape roll, the traction roller assembly 23 is used to output the tape along a preset path, and the pressure plate 24 is located on the side of the discharge end 21 away from the cutter 33, forming an auxiliary support to hold the tape path and effectively preventing the tape from deviating or retracting during the output process.

[0075] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
