[0037] Example 1: See Figures 1-5 The present invention provides a technical solution: a flame-retardant wrapping tape cutting device, comprising a base support 1, a worktable 2 being snapped onto the upper surface of the base support 1, a cutting mechanism 4 being fixedly connected to the upper surface of the worktable 2, a flame-retardant wrapping tape 3 being snapped onto the inside of the cutting mechanism 4, and a guide mechanism 5 being fixedly connected to the outer surface of the base support 1. The cutting mechanism 4 includes:

[0038] U-shaped plate 41, with a screw 411 rotatably connected inside the U-shaped plate 41. A cutting blade 412 is threaded onto the outer surface of the screw 411. A corrugated pipe 413 is sleeved on the outer surface of the screw 411. An arc-shaped baffle 414 is fixedly connected to the lower surface of the U-shaped plate 41. A rubber belt 415 is fixedly connected to the outer surface of the arc-shaped baffle 414. A V-shaped groove 416, a discharge groove 417, and a discharge groove 418 are provided inside the worktable 2. The discharge groove 417 is used to discharge material from the V-shaped groove 416.

[0039] The cutting mechanism 4 also includes an I-beam plate 42, with a threaded post 421 internally threaded. A fixed frame 422 is rotatably connected to the outer surface of the threaded post 421. A rotating groove 423 is provided inside the fixed frame 422. A rotating frame 424 is snapped onto the outer surface of the fixed frame 422. A torsion spring 425 is fixedly connected to the outer surface of the rotating frame 424. A rotating frame 426 is fixedly connected to the outer surface of the torsion spring 425. A roller 427 is rotatably connected to the outer surface of the rotating frame 424. A roller 428 is rotatably connected to the outer surface of the rotating frame 426. The torsion spring 425 is used to torsion the rotating frame 424 and the rotating frame 426.

[0040] The cutting mechanism 4 also includes a frame 43, the outer surface of which is fixedly connected to an arc groove 431, and a barrier net 432 is engaged inside the arc groove 431. A magnetic plate 433 is fixedly connected to the upper surface of the barrier net 432, and the magnetic plate 433 is used to limit the position of the barrier net 432.

[0041] U-shaped plate 41 is fixedly connected to the upper surface of workbench 2, screw 411 is rotatably connected to workbench 2, the lower surface of corrugated pipe 413 is fixedly connected to the upper surface of workbench 2, rubber belt 415 is in contact with the outer surface of cutting blade 412, V-groove 416 has the same cross-sectional shape as cutting blade 412, V-groove 416 is connected to discharge groove 417, and corrugated pipe 413 is used to protect screw 411.

[0042] Rotating groove 423 is rotatably connected to threaded column 421, rotating frame one 424 is rotatably connected to rotating frame two 426, the lower surfaces of roller one 427 and roller two 428 are in contact with the upper surface of flame retardant wrapping tape 3, the lower surface of magnetic plate 433 is in contact with the upper surface of arc groove 431, the barrier net 432 is used to block the cutting material residue, and when the cutting blade 412 moves up and down, the surface of the cutting blade 412 is scraped by rubber belt one 415, thereby preventing the cutting material residue from remaining on the surface of the cutting blade 412.

[0043] When the flame-retardant wrapping tape 3 is cut by the cutting blade 412, the contact between the cutting blade 412 and the upper surface of the worktable 2 makes it difficult for the cutting blade 412 to completely cut the flame-retardant wrapping tape 3, which affects the cutting quality of the flame-retardant wrapping tape 3. Therefore, the cutting mechanism 4 is needed to accommodate the cutting blade 412 so that the cutting blade 412 can completely cut the flame-retardant wrapping tape 3.

[0044] The working principle of this embodiment is as follows: When using this flame-retardant wrapping tape cutting device, the flame-retardant wrapping tape 3 is snapped between the cutting blade 412 and the worktable 2. The flame-retardant wrapping tape 3 is pulled to the cutting position. At this time, the screw 411 is rotated to adjust the distance between the I-beam 42 and the fixed frame 422 so that when the cutting blade 412 contacts the surface of the V-groove 416, the outer surface of the barrier net 432 contacts the side of the U-shaped plate 41. At this time, the screw 411 rotates, driving the cutting blade 412 to move downward and contact the upper surface of the flame-retardant wrapping tape 3. The barrier net 432 is driven downward by the I-beam 42 and the threaded post 421. At this time, the fixed frame 422 pushes the rotating frame 424 and the torsion spring 425 downward, so that the rotating frame 424 and the torsion spring 425 are twisted by the torsion spring 425, thereby causing the roller 427 and the roller 428 to contact the flame-retardant wrapping tape 3. The upper surface of the band 432 contacts and is pressed. At this time, the rotating frame 424 pushes the card frame 43 to move the barrier net 432 towards the center. At this time, the cutting blade 412 cuts the flame-retardant wrapping tape 3 and continues to descend, contacting the surface of the V-groove 416 and the cutting blade 412. At this time, the rotating frame 424 and the rotating frame 426 rotate to 180° on the surface of the flame-retardant wrapping tape 3, and at the same time, the barrier net 432 contacts the surface of the U-shaped plate 41. This prevents the cutting blade 412 and the arc-shaped baffle 414 from cutting the slag from the flame-retardant wrapping tape 3, allowing the slag to be discharged through the discharge chute 1 417 and the discharge chute 2 418. After cutting is completed, the screw 1 411 drives the cutting blade 412 and the I-beam 42 to rise, and the torsion spring 425 causes the rollers 1 427 and 2 428 to slide on the surface of the flame-retardant wrapping tape 3, continuously limiting the flame-retardant wrapping tape 3.

[0045] Example 2: Please refer to Figures 6-8 Based on Embodiment 1, the present invention provides a technical solution: the guiding mechanism 5 includes a telescopic baffle 511, a sliding groove 51 is provided inside the worktable 2, the sliding groove 51 is fixedly connected to the telescopic baffle 511, an elastic band 512 is fixedly connected inside the sliding groove 51, an L-shaped guide plate 513 is fixedly connected to the outer surface of the elastic band 512, a connecting plate 52 is fixedly connected to the outer surface of the worktable 2, a first clamping frame 521 is fixedly connected to the outer surface of the connecting plate 52, a second clamping frame 522 is slidably connected inside the first clamping frame 521, a second rubber band 523 is fixedly connected to the inner wall of the second clamping frame 522, a third rubber band 524 is fixedly connected to the inner wall of the first clamping frame 521, and the L-shaped guide plate 513 is used to guide the flame-retardant wrapping tape 3.

[0046] The upper surface of the telescopic baffle 511 is flush with the upper surface of the worktable 2. The outer surface of the elastic band 512 is fixedly connected to the outer surface of the L-shaped guide plate 513. The outer surface of the L-shaped guide plate 513 is in contact with the side of the flame-retardant wrapping tape 3. Rubber band 2 523 and rubber band 3 524 are used to elastically clamp the flame-retardant wrapping tape 3. The elastic band 512 is used to pull the L-shaped guide plate 513. When the L-shaped guide plate 513 slides inside the sliding groove 51, the telescopic baffle 511 protects the sliding of the L-shaped guide plate 513, thereby preventing the cutting material residue from falling into the sliding groove 51.

[0047] When the flame-retardant wrapping tape 3 is cut by the cutting blade 412, it is difficult for the flame-retardant wrapping tape 3 to be perpendicular to the cutting blade 412, which affects the cutting effect of the cutting blade 412. Therefore, the guiding mechanism 5 is needed to guide the flame-retardant wrapping tape 3 while keeping the flame-retardant wrapping tape 3 perpendicular to the cutting blade 412.

[0048] The working principle of this embodiment is as follows: When using this flame-retardant wrapping tape cutting device, before the flame-retardant wrapping tape 3 is cut by the cutting blade 412, the L-shaped guide plate 513 is pushed to contact the side of the flame-retardant wrapping tape 3, and the L-shaped guide plate 513 is pulled by the elastic band 512 to clamp the flame-retardant wrapping tape 3. The perpendicularity between the L-shaped guide plate 513 and the sliding groove 51 guides the flame-retardant wrapping tape 3, making the flame-retardant wrapping tape 3 perpendicular to the cutting direction of the cutting blade 412. At this time, the hydraulic pump 53... Push the second clamping frame 522 to bring the second rubber strip 523 and the third rubber strip 524 into contact with the surface of the flame-retardant wrapping tape 3. The first clamping frame 521 and the second clamping frame 522 clamp the flame-retardant wrapping tape 3 to keep the surface of the flame-retardant wrapping tape 3 horizontal, so as to prevent the flame-retardant wrapping tape 3 from bending when the L-shaped guide plate 513 clamps the flame-retardant wrapping tape 3. After cutting, the hydraulic pump 53 pushes the second clamping frame 522 in the opposite direction to make the flame-retardant wrapping tape 3 slide on the surface of the second rubber strip 523 and the third rubber strip 524.

[0049] A cutting process for flame-retardant wrapping tape includes the following steps:

[0050] S1. Insert the flame-retardant wrapping tape 3 between the workbench 2 and the cutting blade 412, and guide it through the L-shaped guide plate 513. Rubber tape 2 523 and rubber tape 3 524 clamp it to keep it vertical and horizontal.

[0051] S2. Rotate screw 411 to adjust the position of cutting blade 412. Roller 427 and roller 428 are pressed by torsion spring 425 to extrude flame-retardant wrapping tape 3 to complete pre-fixation.

[0052] S3, the cutting blade 412 descends and, in conjunction with the V-groove 416, cuts the material, while the barrier net 432 and the arc-shaped baffle 414 prevent material debris from splashing.

[0053] S4. After cutting, the cutting blade 412 rises, and the roller 1 427 and roller 2 428 are reset. The material residue is discharged through the discharge chute 1 417 and discharge chute 2 418.

[0054] S5, hydraulic pump 53 adjusts the clamping, flame-retardant wrapping tape 3 feeds, and repeated operation realizes continuous cutting.
