[0001] The utility model belongs to the technical field of tape cutting, and specifically relates to a flame-retardant tape cutting device. Background Art

[0002] The flame-retardant tape cutting device is a professional equipment designed for processing tape materials with flame-retardant properties. It integrates advanced cutting technology and debris cleaning device to ensure the safety of operators, improve the environmental quality while efficiently cutting the flame-retardant tape. Through precise mechanical structure technology, the device realizes accurate and rapid cutting process, and the cutting edge is smooth without secondary processing. Its operation method is simple and convenient, facilitating the operators to quickly get started. At the same time, the maintenance is relatively simple and convenient. The flame-retardant tape cutting device is widely used in the fields of electric power, communication, fire protection, etc., and has become an important tool to improve work efficiency and ensure operation safety.

[0003] In the process of realizing this application, it is found that there are the following problems with this technology: the existing flame-retardant tape cutting device

[0004] does not set up a component for automatically cleaning the cutting debris. The debris generated during the cutting process needs to be manually cleaned, which increases the operation complexity and labor intensity. At the same time, the spacing between the feeding rollers of the flame-retardant tape cannot be adjusted, making it difficult to meet the feeding requirements of flame-retardant tapes with different thicknesses, thus affecting the cutting accuracy.

[0005] Therefore, a flame-retardant tape cutting device is proposed. Content of the Utility Model

[0006] The purpose of the utility model is: in order to reduce the operation complexity and labor intensity and meet the feeding requirements of flame-retardant tapes with different thicknesses, this application provides a flame-retardant tape cutting device.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A flame-retardant tape cutting device includes a workbench. Four groups of support columns are symmetrically arranged on the outer surface of the bottom of the workbench. A set of discharge grooves are arranged on the outer surfaces of the front and back sides of the workbench. Two sets of first support bodies and a set of second support bodies are sequentially arranged on the outer surface of the top of the workbench. A second motor is arranged on the top of each set of first support bodies. A piston cylinder and two sets of limit rings are arranged on the top of the second support body, and the two sets of limit rings are located on both sides of the piston cylinder. A piston rod is arranged at the output end of the piston cylinder. A set of limit rods are slidably connected inside each set of limit rings. The other ends of each set of limit rods and the ends of the piston rod are both connected with a set of lifting blocks. The radius of the outer surface of the top of the limit rod is greater than the inner diameter of the limit ring.

[0009] Further, a cutting table is provided at the bottom of the lifting block, a debris opening is formed between the cutting tables, and compression blocks are connected to the outer surfaces of the two groups of bottoms of the lifting block. A positioning chamber is provided on the periphery of each compression block.

[0010] Further, a number of groups of springs are arranged in parallel on the inner surface of the top of each positioning chamber. The other ends of each group of springs are fixedly connected to the outer surfaces of the corresponding compression blocks. Limiting grooves are formed on the outer surfaces of the tops of each group of positioning chambers, and the outer surfaces of the two compression blocks are slidably connected to the inner surfaces of the limiting grooves.

[0011] Further, a cutting knife is fixedly connected to the outer surface of the bottom of the lifting block, and the debris opening is located directly below the cutting knife.

[0012] Further, a first motor is provided above one of the discharge grooves close to the first support body. The output end of the first motor is connected to a first bidirectional threaded rod. Two first threaded sleeves are rotatably connected to the periphery of the first bidirectional threaded rod. A cleaning brush is connected to the bottom of each first threaded sleeve. A chip collection chamber is arranged inside the workbench, and the two cleaning brushes are both located directly above the chip collection chamber.

[0013] Further, the output end of each second motor is connected to a second bidirectional threaded rod, and the other ends of each second bidirectional threaded rod are rotatably connected to the outer surface of the bottom of the first support body. Two second threaded sleeves are rotatably connected to the periphery of the second bidirectional threaded rod. A rotating limiting chamber is connected to the outer surface of one side where each pair of second threaded sleeves are close to each other.

[0014] Further, a rotating rod is rotatably connected between each pair of rotating limiting chambers, and a feeding roller is arranged on the periphery of each rotating rod.

[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, when the cutting device is used to cut the flame-retardant tape, the flame-retardant tape is sequentially passed through between the two groups of feeding rollers and the top of the cutting table. By starting the corresponding second motor to rotate the second bidirectional threaded rod connected to its output end, since the two threads on the periphery of the second bidirectional threaded rod have opposite directions of rotation, the rotation of the second bidirectional threaded rod can drive the corresponding two groups of rotating limiting chambers to approach or move away from each other. At this time, the flame-retardant tape is closely attached to the two groups of feeding rollers. Pull the flame-retardant tape from the right side of the second support body, and by starting the corresponding piston cylinder to longitudinally move the piston rod connected to its output end, the corresponding two groups of positioning chambers are driven to abut against the cutting table.

[0017] 2. In the present utility model, as the piston rod moves, the compression block squeezes the corresponding spring to expand and contract, so as to limit and fix the corresponding flame-retardant belt. After positioning, the cutting knife precisely cuts the flame-retardant belt. The debris generated by cutting enters the interior of the chip collection chamber through the debris opening holes. By starting the corresponding first motor, the first bidirectional threaded rod connected to its output end rotates. Since the thread directions of the first bidirectional threaded rod are opposite, the rotation of the first bidirectional threaded rod drives the corresponding two groups of first threaded sleeves to move towards or away from each other, so that the cleaning brush effectively cleans the interior of the chip collection chamber. The cleaned debris is discharged outside the device through the two discharge slots. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment

[0024] Refer to Figures 1-4, a flame-retardant tape cutting device, including a workbench 1, four groups of support columns 4 are symmetrically arranged on the bottom outer surface of the workbench 1, a discharge groove 3 is arranged on the front and rear outer surfaces of the workbench 1, two groups of first support bodies 20 and one group of second support bodies 6 are sequentially arranged on the top outer surface of the workbench 1, a second motor 21 is arranged on the top of each group of first support bodies 20, a piston cylinder 7 and two groups of limit rings 8 are arranged on the top of the second support body 6, and the two groups of limit rings 8 are located on both sides of the piston cylinder 7. A piston rod 14 is arranged at the output end of the piston cylinder 7. A limit rod 26 is slidably connected inside each group of limit rings 8. A lifting block 13 is connected to the other end of each group of limit rods 26 and the end of the piston rod 14. The radius of the outer surface of the top of the limit rod 26 is greater than the inner diameter of the limit ring 8. Specifically, through the cooperation of the above structures, the complexity and labor intensity of the operation can be reduced, and the feeding requirements of flame-retardant tapes with different thicknesses can be adapted.

[0025] Refer to Figures 1-4 , a cutting table 5 is arranged at the bottom of the lifting block 13, a debris opening 27 is arranged between the cutting tables 5, two groups of compression blocks 16 are connected to the bottom outer surfaces of the lifting block 13. A positioning chamber 18 is arranged around each group of compression blocks 16. Specifically, the compression block 16 connected to the bottom of the lifting block 13 plays a role in stabilizing the cutting force and direction. The positioning chamber 18 surrounding the compression block 16 ensures the precise positioning during the cutting process, improving the overall cutting efficiency and accuracy. A number of springs 19 are arranged in parallel on the inner surface of the top of each group of positioning chambers 18. The other end of each group of springs 19 is fixedly connected to the outer surface of the other side of the corresponding compression block 16. A limit groove 17 is arranged on the outer surface of the top of each group of positioning chambers 18, and the outer surfaces of the two groups of compression blocks 16 are slidably connected to the inner surface of the limit groove 17. Specifically, as the piston rod 14 moves, the compression block 16 will squeeze the corresponding spring 19 to expand and contract, thereby limiting and fixing the corresponding flame-retardant tape.

[0026] Refer to Figures 1-4, a set of cutting knives 15 are fixedly connected to the outer bottom of the lifting block 13, and the debris opening 27 is located directly below the cutting knives 15. Specifically, the debris generated by cutting enters the inside of the debris collection chamber 28 through the debris opening 27. By starting the corresponding first motor 2, the first bidirectional threaded rod 10 connected to the output end thereof rotates. Above a set of discharge grooves 3 near the first support body 20, there is a first motor 2. The output end of the first motor 2 is connected to a first bidirectional threaded rod 10. Two groups of first threaded sleeves 12 are rotatably connected to the periphery of the first bidirectional threaded rod 10. A set of cleaning brushes 9 are connected to the bottom of each group of first threaded sleeves 12. A debris collection chamber 28 is arranged inside the workbench 1. The two groups of cleaning brushes 9 are both located directly above the debris collection chamber 28. Specifically, the debris generated by cutting enters the inside of the debris collection chamber 28 through the debris opening 27. By starting the corresponding first motor 2, the first bidirectional threaded rod 10 connected to the output end thereof rotates.

[0027] Referring to Figures 1-4 , the output end of each group of second motors 21 is connected to a set of second bidirectional threaded rods 22, and the other end of each group of second bidirectional threaded rods 22 is rotatably connected to the outer surface of the bottom of the first support body 20. Two groups of second threaded sleeves 23 are rotatably connected to the periphery of the second bidirectional threaded rod 22. A set of rotation limiting chambers 24 are connected to the outer surface of the side where each group of second threaded sleeves 23 are close to each other. Specifically, by starting the corresponding second motor 21, the second bidirectional threaded rod 22 connected to the output end thereof rotates. Since the two sets of threads on the periphery of the second bidirectional threaded rod 22 have opposite directions of rotation, the rotation of the second bidirectional threaded rod 22 can drive the corresponding two sets of rotation limiting chambers 24 to approach or move away from each other. A set of rotating rods 25 are rotatably connected between each pair of rotation limiting chambers 24, and a set of feeding rollers 11 are arranged on the periphery of each group of rotating rods 25. Specifically, the rotation of the second bidirectional threaded rod 22 can drive the corresponding two sets of rotation limiting chambers 24 to approach or move away from each other. At this time, the flame retardant tape is closely attached to the two sets of feeding rollers 11.

[0028] The implementation principle of the embodiment of a flame retardant tape cutting device of the present application is as follows:

[0029] When using the cutting device to cut the flame retardant tape, the flame retardant tape is sequentially passed through between the two sets of feeding rollers 11 and over the top of the cutting table 5. By starting the corresponding second motor 21, the second bidirectional threaded rod 22 connected to the output end thereof rotates. Since the two sets of threads on the periphery of the second bidirectional threaded rod 22 have opposite directions of rotation, the rotation of the second bidirectional threaded rod 22 can drive the corresponding two sets of rotation limiting chambers 24 to approach or move away from each other. At this time, the flame retardant tape is closely attached to the two sets of feeding rollers 11. Pull the flame retardant tape from the right side of the second support body 6. By starting the corresponding piston cylinder 7, the piston rod 14 connected to the output end thereof moves longitudinally, thereby driving the corresponding two sets of positioning chambers 18 to abut against the cutting table 5.

[0030] On the other hand, as the piston rod 14 moves, the compression block 16 squeezes the corresponding spring 19 to expand and contract, so as to limit and fix the corresponding flame-retardant belt, and the positioned cutting knife 15 precisely cuts the flame-retardant belt. The generated debris enters the inside of the chip collection cavity 28 through the debris opening 27. By starting the corresponding first motor 2, the first bidirectional threaded rod 10 connected to the output end thereof rotates. Since the thread directions of the first bidirectional threaded rod 10 are opposite, the rotation of the first bidirectional threaded rod 10 drives the corresponding two groups of first threaded sleeves 12 to move towards or away from each other, so that the cleaning brush 9 effectively cleans the inside of the chip collection cavity 28, and the cleaned debris is discharged outside the device through the two discharge grooves 3.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
