[0026] Through the above technical solution, the automatic tensioning component 4 is set to achieve accurate adjustment of the tension of the tape 3, increase the adjustable range, and improve the production quality of the tape 3. When in use, the motor 402 is started, and the motor 402 drives the positive and negative screws 403 to rotate. The rotation of the positive and negative screws 403 drives the symmetrically arranged moving blocks 404 to move relative to each other. The relative movement of the symmetrically arranged moving blocks 404 drives the symmetrically arranged rotating shafts 405 to move relative to each other. The relative movement of the symmetrically arranged rotating shafts 405 drives the symmetrically arranged tensioning rollers 406 to move relative to each other, thereby changing the relative distance between the symmetrically arranged tensioning rollers 406, adjusting the tension of the tape 3, and setting the detachable component 7 to achieve The sliding plate 5 can be quickly fixed and disassembled to facilitate the inspection and maintenance of the parts in the shell 1. When in use, the sliders 6 set on both sides of the sliding plate 5 are slid into the shell 1. When the slot 705 slides to the position corresponding to the latch 704, the latch 704 is stuck in the slot 705. When the sliding plate 5 needs to be disassembled, the pressing rod 709 is pressed. The pressing rod 709 moves to drive the connecting block 703 to move. The connecting block 703 moves to compress the second spring 708. At the same time, the connecting block 703 moves to drive the latch 704 to move and compress the first spring 702. The latch 704 moves and disengages from the slot 705, which facilitates the sliding slider 6 to disassemble the sliding plate 5.

[0027] Specifically, the slider 6 is slidably connected to the housing 1 , the fixed bin 401 is fixedly arranged on one side of the housing 1 , the motor 402 is fixedly arranged in the fixed bin 401 , and the output end of the motor 402 is detachably connected to the forward and reverse screw rods 403 .

[0028] Through the above technical solution, the slider 6 is slidably connected to the shell 1, which makes it convenient to slide the sliding plate 5 out for disassembly and installation. The motor 402 is externally connected to the power supply and controller, which is convenient for ensuring the independent operation of each device. When in use, the motor 402 drives the forward and reverse screw rods 403 to rotate.

[0029] Specifically, there are multiple groups of moving blocks 404 , which are symmetrically distributed on the outside of the forward and reverse screw rods 403 , and screw holes matching the forward and reverse screw rods 403 are opened in the moving blocks 404 .

[0030] Through the above technical solution, the motor 402 drives the forward and reverse screw rods 403 to rotate, so that the rotation of the forward and reverse screw rods 403 drives the symmetrically arranged moving blocks 404 to move relative to each other.

[0031] Specifically, the rotating shaft 405 is fixedly connected to the moving block 404 , and the tensioning roller 406 is rotatably connected to the rotating shaft 405 . The rotating shaft 405 is divided into multiple groups, and the multiple groups of rotating shafts 405 are symmetrically arranged at both ends of the tensioning roller 406 .

[0032] Through the above technical solution, the symmetrically arranged moving blocks 404 move relative to each other, driving the symmetrically arranged rotating shaft 405 to move relative to each other. The symmetrically arranged rotating shaft 405 moves relative to each other, driving the symmetrically arranged tensioning roller 406 to move relative to each other. The symmetrically arranged tensioning roller 406 moves relative to each other, causing the relative distance between the symmetrically arranged tensioning rollers 406 to change. The rotating shaft 405 is rotatably connected to the tensioning roller 406, thereby facilitating the transmission of the adhesive tape 3.

[0033] Specifically, the slide rail 407 is fixedly arranged inside the housing 1 , and the rotating shaft 405 of the tensioning roller 406 arranged on one side close to the slide rail 407 is slidably connected to the slide rail 407 .

[0034] Through the above technical solution, the rotating shaft 405 slides in the slide rail 407, and the slide rail 407 makes the symmetrically arranged tensioning rollers 406 more stable when changing the distance, thereby playing a certain supporting role.

[0035] Specifically, the slot 705 matches the latch 704 , the connecting block 703 is fixedly connected to the first spring 702 , the connecting block 703 is fixedly connected to the second spring 708 , the connecting block 703 is slidably connected to the first slide groove 706 , and the connecting block 703 is slidably connected to the second slide groove 710 .

[0036] Through the above technical solution, when the pin 704 is stuck in the slot 705, it is convenient to fix the sliding plate 5. When the connecting block 703 moves, the first spring 702 is compressed, and the pin 704 moves and disengages from the slot 705, making it convenient to disassemble the sliding plate 5. The first slide groove 706 and the second slide groove 710 facilitate the movement of the connecting block 703.

[0037] Specifically, the pressing rod 709 is fixedly disposed on the upper end of the connecting block 703 , the latch 704 is fixedly disposed on the upper end of the connecting block 703 , and the pressing rod 709 is slidably connected to the pressing chamber 707 .

[0038] Through the above technical solution, the movement of the pressing rod 709 drives the connecting block 703 to move, and the movement of the connecting block 703 compresses the second spring 708. At the same time, the movement of the connecting block 703 drives the latch 704 to move, so that the latch 704 moves and disengages from the slot 705. The first spring 702 and the second spring 708 facilitate the connection block 703 to reset.

[0039] When in use, when the tension needs to be adjusted, the motor 402 is started, and the motor 402 drives the forward and reverse screw rods 403 to rotate. The rotation of the forward and reverse screw rods 403 drives the symmetrically arranged moving blocks 404 to move relative to each other. The relative movement of the symmetrically arranged moving blocks 404 drives the symmetrically arranged rotating shafts 405 to move relative to each other. The relative movement of the symmetrically arranged rotating shafts 405 drives the symmetrically arranged tensioning rollers 406 to move relative to each other. The symmetrically arranged tensioning rollers 406 move relative to each other, so that the relative distance between the symmetrically arranged tensioning rollers 406 changes. The relative distance between the symmetrically arranged tensioning rollers 406 changes to tighten the adhesive tape 3. When the sliding plate 5 needs to be opened to inspect the shell 1, the pressing rod 709 is pressed. The pressing rod 709 moves to drive the connecting block 703 to move. The connecting block 703 moves to compress the second spring 708. At the same time, the connecting block 703 moves to drive the latch 704 to move and compress the first spring 702. The latch 704 moves to disengage from the slot 705, and the sliding slider 6 removes the sliding plate 5.
