Description

Technical Field

[0001] This utility model relates to the field of thread cutting devices, specifically a long thread cutting device. Background Technology

[0002] Cables are a general term for items such as optical fibers and electrical cables. Cables have many uses, primarily for control installation, equipment connection, and power transmission, making them a common and indispensable part of daily life. Because cables are live, their installation requires special care.

[0003] When using cables, different lengths are required, which necessitates the use of a cable cutting device. Normally, cables can be cut directly with special scissors, but due to the different thicknesses of the cables, some cables cannot be cut in one go when using scissors, resulting in many burrs and gaps at the cable ends, making them inconvenient to use. This is where the use of a cable cutting device comes in.

[0004] However, when the wire cutting device is used now, the cable ends separate from the cutting blade after it is cut because it loses its tension. This causes the cable ends to fall outside the wire cutting device, making it unusable and requiring the cable to be repositioned, which reduces production efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that in current wire cutting devices, after cutting the cable, the cable end separates from the cutting blade due to the loss of tension, causing the cable end to fall outside the wire cutting device and become unusable, requiring subsequent repositioning of the cable and reducing production efficiency, this utility model proposes a long wire cutting device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4As shown, a long thread cutting device includes a base 1. Two placement blocks 2 are fixedly connected to the top of the base 1. A winding roller 3 is rotatably connected inside the placement blocks 2, and a thread roll 4 is rotatably connected to the outside of the winding roller 3. A mounting platform 5 is fixedly connected to the top of the base 1. A clamping assembly is provided on the top of the mounting platform 5. The clamping assembly includes a mounting frame 6 fixedly connected to the top of the mounting platform 5. A motor 7 is fixedly connected inside the mounting frame 6. A screw 8 is fixedly connected to the transmission end of the motor 7. There are two screws 8. A first one-way bearing 9 is rotatably connected between the two screws 8. The end of the screw 8 is rotatably connected to the inside of the mounting frame 6, and two transmission pins are threadedly connected to the outside of the screw 8. The moving block 11 and the transmission block 11 pass through the mounting frame 6 and are slidably connected. There are six transmission blocks 11, which are divided into three groups. The other two groups of transmission blocks 11 are slidably connected to the first slide rod 12. The two ends of the first slide rod 12 are fixedly connected to the inside of the mounting frame 6. The top of the transmission block 11 is fixedly connected to the guide limit frame 13. The guide limit frame 13 is slidably connected to the second slide rod 14. The end of the second slide rod 14 is fixedly connected to the clamping block 15. Two limit blocks 16 are fixedly connected to the outside of the second slide rod 14. The outside of the second slide rod 14 is slidably connected to the slide cylinder 17. The limit block 16 passes through the slide cylinder 17 and is slidably connected.

[0027] During operation, the motor 7 drives the first screw 8 to rotate, and the first one-way bearing 9 ensures that only the forward rotation power can be transmitted to the second screw 8, thereby driving the transmission block 11 to move, which in turn drives the guide limit frame 13 to move, and then drives the second slide rod 14 to move inside the slide cylinder 17, thereby driving the clamping block 15 to clamp the cable. This restricts the position and height of the cable, so that when the cable is cut, the end of the cable will not change position significantly, thus preventing the end of the cable from detaching from the device and eliminating the need for subsequent adjustments to the cable's position, thereby improving production efficiency.

[0028] The slide cylinder 17 is provided with a pulling component on its outer side. The pulling component includes a rack 18 fixedly connected to the outer side of the slide cylinder 17. A limit plate 19 is slidably connected to the outer side of the rack 18. The outer side of the limit plate 19 is fixedly connected to the inside of the mounting frame 6. A second gear 20 is meshed on the outer side of the rack 18. A transmission rod 21 is fixedly connected inside the second gear 20.

[0029] The pulling assembly also includes a transmission rod 21 fixedly connected inside the second gear 20.

A toothed chain 24 meshes with the outside of the third gear 23. A first gear 10 meshes with the inside of the toothed chain 24. The inside of the first gear 10 is fixedly connected to the outside of one of the screws 8.

[0030] During operation, the motor 7 drives the first screw 8 to reverse, which in turn drives the first gear 10 to rotate, thereby driving the gear chain 24 to rotate, which in turn drives the third gear 23 to rotate, which in turn drives the transmission rod 21 to rotate. The second one-way bearing 22 ensures that only the power of the first screw 8 reversing can be transmitted to the second transmission rod 21, which in turn drives the second gear 20 to rotate, thereby driving the rack 18 to move, which in turn drives the slide cylinder 17 to move, which in turn drives the clamping block 15 to move, thus moving the cable towards the cutting assembly, which facilitates the subsequent cutting of the cable.

[0031] The mounting frame 6 is provided with a cutting assembly on its outer side. The cutting assembly includes a mounting bracket 29 fixedly connected to the top of the mounting frame 6, and a hydraulic rod 30 fixedly connected to the bottom of the mounting bracket 29.

[0032] The cutting assembly also includes a blade 31 fixedly connected to the bottom of the hydraulic rod 30, a blade holder 32 slidably connected to the outside of the blade 31, and the bottom of the blade holder 32 fixedly connected to the bottom of the inner cavity of the mounting frame 6.

[0033] During operation, the hydraulic rod 30 drives the blade 31 to move, thereby making the blade 31 slide in connection with the inside of the blade holder 32, which can then cut the cable.

[0034] The mounting frame 6 is equipped with a guide assembly, which includes a first placement seat 25 fixedly connected to the bottom of the inner cavity of the mounting frame 6. A guide tube 26 is fixedly connected inside the first placement seat 25. An auxiliary tube 28 is fixedly connected to the end of the guide tube 26. The inside of the guide tube 26 communicates with the inside of the auxiliary tube 28. A second placement seat 27 is fixedly connected to the bottom of the auxiliary tube 28. The bottom of the second placement seat 27 is fixedly connected to the bottom of the inner cavity of the mounting frame 6. The inside of the auxiliary tube 28 is slidably connected to the outside of the clamping block 15.

[0035] During operation, the resistance between the guide tube 26 and the cable restricts the position of the cable, while the auxiliary tube 28 keeps part of the cable inside the auxiliary tube 28, which facilitates the clamping components to clamp the cable.

[0036] Example 2

[0037] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the top of the base 1 is provided with a resistance-increasing component. The resistance-increasing component includes two support columns 33 fixedly connected to the top of the base 1. A sliding column 35 is slidably connected inside the support column 33. A resistance-increasing frame 36 is fixedly connected to the end of the sliding column 35. A resistance-increasing rubber block 37 is fixedly connected inside the resistance-increasing frame 36 by bolts.

[0038] The resistance-increasing component also includes a limiting frame 34 fixedly connected to the top of the support column 33. A third slide rod 38 is slidably connected inside the limiting frame 34. The third slide rod 38 passes through the support column 33 and is slidably connected. The outer side of the third slide rod 38 is slidably connected to the inside of the slide column 35. A limiting plate 39 is fixedly connected to the outer side of the third slide rod 38. A spring 40 is fixedly connected between the top of the limiting plate 39 and the bottom of the limiting frame 34.

[0039] During operation, pulling the third slide bar 38 moves the limiting plate 39, compressing the spring 40 and separating the third slide bar 38 from the slide column 35. Then, pushing the slide column 35 allows the resistance-increasing rubber block 37 to contact the outside of the wire coil 4. The third slide bar 38 is then placed inside the slide column 35 to restrict its position. The contact between the resistance-increasing rubber block 37 and the wire coil 4 increases the pulling force on the cable, keeping it taut and reducing the possibility of cutting errors.

[0040] The working principle is as follows: the motor 7 drives the first screw 8 to rotate, and the first one-way bearing 9 ensures that only the forward rotation power can be transmitted to the second screw 8, thereby driving the transmission block 11 to move, which in turn drives the guide limit frame 13 to move, and then drives the second slide rod 14 to move inside the slide cylinder 17, thereby driving the clamping block 15 to clamp the cable. This restricts the position and height of the cable, so that when the cable is cut, the end of the cable will not change position significantly, thus preventing the end of the cable from detaching from the device. This eliminates the need for subsequent adjustments to the cable position, thereby improving production efficiency.

[0041] The motor 7 drives the first screw 8 to reverse, which in turn drives the first gear 10 to rotate, thereby driving the gear chain 24 to rotate, which in turn drives the third gear 23 to rotate, which in turn drives the transmission rod 21 to rotate. The second one-way bearing 22 ensures that only the power of the first screw 8 reversing can be transmitted to the second transmission rod 21, so that the second transmission rod 21 can drive the second gear 20 to rotate, which in turn drives the rack 18 to move, which in turn drives the slide cylinder 17 to move, which in turn drives the clamping block 15 to move, thus moving the cable towards the cutting assembly, so as to facilitate the subsequent cutting of the cable.
