Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, and in particular to a pressing mechanism for a laser-coded rewinding machine. Background Technology

[0002] In laser marking and rewinding machines, the clamping mechanism is a key component that ensures product labels or packaging materials remain flat and in close contact during processing.

[0003] However, the design of traditional clamping mechanisms mainly relies on a fixed clamping force, which is not convenient for providing uniform pressure when dealing with rolls of different thicknesses and materials, resulting in poor clamping effect. This not only affects the appearance quality of the product, but may also lead to inaccurate laser marking, and even affect the operating efficiency of the equipment. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pressing mechanism for a laser marking and rewinding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pressing mechanism for a laser marking and rewinding machine includes a mounting frame. A fixed frame is fixedly connected to the bottom of the mounting frame, and a fixed plate is fixedly connected to the upper surface of the fixed frame. Multiple connecting shafts are movably connected to the fixed plate, and a sliding plate is fixedly connected between the multiple connecting shafts. A threaded rod is movably connected to the fixed frame and is rotatably connected to the sliding plate. A guide plate is mounted on one side of the sliding plate via a connecting assembly, and two triangular blocks are mounted on one side of the guide plate via a guide assembly. The guide assembly includes two dovetail grooves, which are formed on both sides of the guide plate. The triangular blocks are slidably connected to the dovetail grooves, and a connecting rod is movably connected between the two triangular blocks. A rubber roller is fixedly connected to the connecting rod, and an anti-slip pad is fixedly connected inside the dovetail groove, and the anti-slip pad is in pressure contact with the triangular block. A guide roller is movably connected to the top of the fixed frame.

[0006] As a further embodiment of this utility model, a wire feeding roller is movably connected to one side of the mounting frame, and a motor is fixedly connected to one side of the mounting frame, with one end of the motor output shaft fixed to the wire feeding roller.

[0007] As a further embodiment of this utility model, a locking nut is movably connected to one end of the threaded rod extending out of the fixing plate, and the locking nut is in contact with the fixing plate by compression.

[0008] As a further embodiment of this utility model, the connecting assembly includes multiple guide shafts, which are fixed to one side of the guide plate by bolts and are slidably connected to the slide plate. A spring is sleeved on the outside of the guide shaft, and the two ends of the spring are fixed to the guide plate and the slide plate respectively.

[0009] As a further embodiment of this invention, the guide roller is located between the wire feeding roller and the rubber roller.

[0010] As a further improvement of this utility model, a guide frame is fixedly connected to one side of the mounting frame.

[0011] As a further embodiment of this invention, the guide frame is located above the guide plate.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model enables the adjustment of the gap between the rubber roller and the guide roller, making it convenient for workers to press tapes of different thicknesses, thus expanding the applicability of the device, preventing the tape from easily deviating during rewinding, and improving the flexibility of the device.

[0013] 2. This utility model uses guide rollers to guide the tape, ensuring that the tape maintains the correct path during movement and pressing, which helps improve rewinding quality and further reduces defects caused by tape misalignment.

[0014] 3. In this utility model, the locking nut and the fixing plate are in extrusive contact, which can further restrict the position of the threaded rod, prevent the threaded rod from rotating randomly after adjustment, and improve the stability of the threaded rod in use.

[0018] Reference Figures 1-3 A pressing mechanism for a laser marking and rewinding machine includes a mounting frame 2. A wire feeding roller 13 is rotatably connected to one side of the mounting frame 2. A motor 1 is fixed to one side of the mounting frame 2 by bolts, and one end of the output shaft of the motor 1 is fixed to the wire feeding roller 13. The rotation of the motor 1 causes the wire feeding roller 13 to rotate, thereby assisting in the conveying of the tape. A fixing frame 8 is fixed to the bottom of the mounting frame 2 by bolts. A fixing plate 7 is fixed to the upper surface of the fixing frame 8 by bolts. Multiple connecting shafts 6 are slidably connected to the fixing plate 7. A sliding plate 9 is fixed between the multiple connecting shafts 6 by bolts. A threaded rod 4 is threadedly connected to the fixing frame 8, and the threaded rod 4 is rotatably connected to the sliding plate 9. A guide plate 10 is installed on one side of the sliding plate 9 through a connecting assembly. Two triangular blocks 16 are installed on one side of the guide plate 10 through a guide assembly. Rotating the threaded rod 4 causes the sliding plate 9 to move, thereby causing the guide plate 10 to move through the connecting assembly.

[0019] It should be noted that the guide assembly includes two dovetail grooves 14, which are formed on both sides of the guide plate 10. Triangular blocks 16 are slidably connected to the dovetail grooves 14, and a connecting rod 17 is rotatably connected between the two triangular blocks 16. A rubber roller 11 is fixed to the connecting rod 17 by bolts. Rotating the threaded rod 4 moves the slide plate 9, thereby adjusting the position of the rubber roller 11 and allowing adjustment of the distance between the rubber roller 11 and the guide roller 12. This facilitates adaptation to different thicknesses of adhesive tape. An anti-slip pad 15 is adhered inside the dovetail groove 14, and the anti-slip pad 15 is in contact with the triangular blocks 16. The anti-slip pad 15 increases the friction between the triangular blocks 16 and the dovetail groove 14. The top of the fixed frame 8 is rotatably connected to a guide roller 12, which guides the tape. The guide plate 10 moves, causing the guide roller 11 to gradually move closer to or away from the guide roller 12. The connecting assembly includes multiple guide shafts 3, which are fixed to one side of the guide plate 10 by bolts. The guide shafts 3 are slidably connected to the slide plate 9. The guide shafts 3 provide guidance for the movement of the guide plate 10. A spring 18 is sleeved on the outside of the guide shaft 3, and the two ends of the spring 18 are fixed to the guide plate 10 and the slide plate 9, respectively. During the process of the tape being pressed by the tape roller 11, the spring 18 can adaptively adjust the pressure according to the unevenness of the tape surface, etc., to avoid excessive pressure damaging the tape.

[0020] In particular, the threaded rod 4 extends out of the fixed plate 7 and is threadedly connected to a locking nut 5, and the locking nut 5 is in contact with the fixed plate 7. The locking nut 5 can further restrict the position of the threaded rod 4. The guide roller 12 is located between the wire feeding roller 13 and the rubber roller 11. A guide frame is fixed to one side of the mounting frame 2 by bolts. The guide frame is located above the guide plate 10.

[0021] Working principle: When it is necessary to tighten the tape during the rewinding process, the threaded rod 4 is rotated to adjust the distance between the rubber roller 11 and the guide roller 12. That is, rotating the threaded rod 4 causes the sliding plate 9 to move, thereby moving the guide plate 10 through the connecting assembly. This causes the rubber roller 11 to gradually move closer to or further away from the guide roller 12. Rotating the locking nut 5 makes it press against the fixing plate 7, thereby further fixing the position of the threaded rod 4. This allows the device to adjust the distance between the rubber roller 11 and the guide roller 12 according to the thickness of the tape, making it convenient for workers to tighten the tape according to its thickness and preventing the tape from running off-track.
