[0001] This utility model relates to the field of tape slitting technology, and in particular to an anti-loosening device for a tape slitting machine. Background Technology
[0002] Coated tape is typically cut into multiple usable segments using a machine with multiple combined cutters. This machine cuts long, tubular rolls of tape into usable segments in one go. During the cutting process, the cutting depth of the cutters needs to be controlled to prevent them from cutting too deeply and damaging other components. Currently, this is controlled manually, but this method is not accurate.
[0003] A tape slitting machine is disclosed in the prior art patent application with publication number CN202321763U3. By adding a sensor, when the cutter on the combined blade cuts into place, the sensor can automatically send a signal to the control circuit of the slitting machine. The control circuit controls the cutter to stop cutting and retract, thereby preventing the problem of over-cutting.
[0004] However, in the existing technology, the device does not have a structure to adjust the tension of the tape, which makes the tape easy to loosen when it is cut, thus affecting the cutting effect. Utility Model Content
[0005] The purpose of this invention is to provide an anti-loosening device for a tape slitting machine, which aims to solve the problem in the prior art that the device does not have a structure to adjust the tape tension, making the tape easy to loosen when being cut, thus affecting the cutting effect.

The anti-loosening mechanism includes a first mounting rod, a second mounting rod, a first rotating roller, a second rotating roller, a drive assembly, a lifting assembly, a moving rod, and a pressure roller. The first mounting rod is rotatably connected to one end of the mounting frame, and the second mounting rod is rotatably connected to the other end of the mounting frame. The first and second mounting rods are located within the mounting frame. The first rotating roller is fixedly connected to the first mounting rod, and the second rotating roller is fixedly connected to the second mounting rod. The drive assembly is located at one end of the mounting frame, and the first and second mounting rods are located at the output end of the drive assembly. The lifting assembly is located on the mounting frame, and the moving rod is located at the output end of the lifting assembly. The pressure roller is rotatably connected to the moving rod.
[0007] The drive assembly includes a power kit and two driven gears. The power kit is mounted on the mounting frame, and the two driven gears are fixedly connected to the first mounting rod and the second mounting rod, respectively. The two driven gears are located on the output end of the power kit.
[0008] The power kit includes a mounting bracket, a drive motor, a drive shaft, and a drive gear. The mounting bracket is fixedly connected to the mounting frame, the drive motor is fixedly connected to the mounting bracket, the drive shaft is fixedly connected to the output end of the drive motor and extends into the mounting bracket, the drive gear is fixedly connected to the drive shaft, and the drive gear meshes with two driven gears.
[0009] The lifting assembly includes a threaded rod, a moving block, and a limiting kit. The mounting frame has a mounting groove. The threaded rod is rotatably connected to the mounting frame and located within the mounting groove. The moving block is threadedly connected to the threaded rod and slidably connected to the mounting frame. One end of the moving rod is fixedly connected to the moving block, and the limiting kit is located at the other end of the moving rod.

[0019] This utility model provides an anti-loosening device for a tape slitting machine, including a mounting frame 101 and an anti-loosening mechanism. The anti-loosening mechanism includes a first mounting rod 102, a second mounting rod 103, a first rotating roller 104, a second rotating roller 105, a drive assembly, a lifting assembly, a moving rod 113, and a pressure roller 114.

The limiting assembly includes a guide post 115 and a sliding block 116. The aforementioned solution solves the problem in the prior art where the device does not have a structure to adjust the tape tension, making the tape prone to loosening during cutting and thus affecting the cutting effect.
[0020] In this embodiment, the first mounting rod 102 is rotatably connected to one end of the mounting frame 101, and the second mounting rod 103 is rotatably connected to the other end of the mounting frame 101. The first mounting rod 102 and the second mounting rod 103 are located within the mounting frame 101. The first rotating roller 104 is fixedly connected to the first mounting rod 102, and the second rotating roller 105 is fixedly connected to the second mounting rod 103. The driving assembly is disposed at one end of the mounting frame 101. The first mounting rod 102 and the second mounting rod 103 are disposed at the output end of the driving assembly. The lifting assembly is disposed on the mounting frame 101, and the moving rod 113 is disposed on the... At the output end of the lifting assembly, the pressure roller 114 is rotatably connected to the moving rod 113. When using this invention to cut tape, the tape passes through the first rotating roller 104, the second rotating roller 105, and the pressure roller 114. The driving assembly drives the first rotating roller 104 and the second rotating roller 105 to rotate, causing the tape to move. When the tape becomes loose, the lifting assembly controls the moving rod 113 and the pressure roller 114 to move downwards. The distance between the pressure roller 114 and the first rotating roller 104 and the second rotating roller 105 increases, and the tape is gradually stretched until it is taut, ensuring that the tape will not become loose during cutting, thereby improving the tape cutting effect.
[0021] Furthermore, the power kit is mounted on the mounting frame 101, and the two driven gears 110 are fixedly connected to the first mounting rod 102 and the second mounting rod 103 respectively. The two driven gears 110 are located on the output end of the power kit.
[0022] Furthermore, the mounting bracket 106 is fixedly connected to the mounting frame 101, the drive motor 107 is fixedly connected to the mounting bracket 106, the drive shaft 108 is fixedly connected to the output end of the drive motor 107 and extends into the mounting bracket 106, the drive gear 109 is fixedly connected to the drive shaft 108, and the drive gear 109 meshes with the two driven gears 110.
[0023] In this embodiment, when using the present invention to cut the tape, the tape passes through the first rotating roller 104, the second rotating roller 105, and the pressure roller 114. The drive motor 107 is started, and the drive motor 107 drives the drive shaft 108 and the driving gear 109 to rotate. The driving gear 109 meshes with the two driven gears 110 and drives the two driven gears 110 to rotate. The two driven gears 110 drive the first rotating roller 104 and the second rotating roller 105 to rotate, thus moving the tape.
[0024] Furthermore, the mounting frame 101 has a mounting groove 117, the threaded rod 111 is rotatably connected to the mounting frame 101 and located in the mounting groove 117, the movable block 112 is threadedly connected to the threaded rod 111 and slidably connected to the mounting frame 101, one end of the movable rod 113 is fixedly connected to the movable block 112, and the limiting kit is disposed at the other end of the movable rod 113.
[0025] In this embodiment, when the tape becomes loose, the threaded rod 111 is rotated, which drives the moving block 112 to move downward. The moving block 112 then drives the moving rod 113 and the pressure roller 114 to move downward. The distance between the pressure roller 114 and the first rotating roller 104 and the second rotating roller 105 increases, and the tape is gradually stretched until it is taut, ensuring that the tape will not loosen during slitting, thereby improving the tape slitting effect.
[0026] Furthermore, the guide post 115 is fixedly connected to the mounting frame 101, the sliding block 116 is slidably connected to the guide post 115, and one end of the moving rod 113 is fixedly connected to the sliding block 116.
[0027] In this embodiment, when the moving rod 113 and the pressure roller 114 move downward, the sliding block 116 slides on the guide post 115, which plays a limiting and guiding role in the movement of the moving rod 113 and the pressure roller 114.
[0028] When using this invention to slit tape, the tape passes through the first rotating roller 104, the second rotating roller 105, and the pressure roller 114. The drive motor 107 is activated, driving the drive shaft 108 and the drive gear 109 to rotate. The drive gear 109 meshes with two driven gears 110, driving them to rotate. The two driven gears 110 then drive the first rotating roller 104 and the second rotating roller 105 to rotate, causing the tape to move. When the tape becomes loose, the threaded rod 111 is rotated, causing the moving block 112 to move downwards. The moving block 112 then drives the moving rod 113 and the pressure roller 114 to move downwards. The distance between the pressure roller 114 and the first rotating roller 104 and the second rotating roller 105 increases, gradually stretching the tape until it is taut. This ensures the tape will not loosen during slitting, thereby improving the tape slitting effect.
