The bottom surface of the limiting frame 15 is connected to the surface of the base frame 6. The top opening of the recycling box 14 is fitted with a sealing strip 16. In this design, the cable cutting machine body 1, support frame 2, cylinder 3, upper cutter 4 and lower cutter 5 constitute the main body of the pneumatic cable cutting machine. A large number of related components are set in the main body of the pneumatic cable cutting machine. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.

[0024] The main model of the pneumatic cable cutter in this solution is: JL-W430.

[0025] Preferably, the retaining ring 7 has a semi-circular structure, and the shape and size of the inner wall of the retaining ring 7 are adapted to the longitudinal end of the support frame 2.

[0026] In practical use, the retaining ring 7 is used to engage and fix the protective cover 8 connected to it on the surface of the cable cutter body 1 by engaging and fixing it to the longitudinal end of the support frame 2.

[0027] Preferably, the inner wall surface of the sealing strip 16 is fitted with the top cover 17, the top surface of the top cover 17 abuts against the inner wall of the base frame 6, and the recycling box 14 is provided with an air inlet pipe 18 on the side away from the second threaded pipe 13, and the other side of the air inlet pipe 18 is threadedly connected to the filter box 19.

[0028] In practical use, the sealing strip 16 and the top cover 17 are respectively fitted and fixed onto the recycling box 14. The sealing strip 16 fills the gap between the recycling box 14 and the top cover 17 to prevent dust from escaping from the gap. At the same time, the grooves on the inner wall of the base frame 6 that are adapted to the height of the recycling box 14 and the top cover 17 are fitted and squeezed to connect the two, so that a sealed space is formed inside the recycling box 14 after it is placed, which facilitates the collection of dust and debris generated by cutting on the body 1 of the cable cutting machine.

[0029] Preferably, a filter screen 20 is installed on the side of the filter box 19 away from the air inlet pipe 18, and the other side of the filter box 19 is threaded to the air inlet of the centrifugal fan 21. The bottom of the centrifugal fan 21 is installed on the surface of the base frame 6. The bottom discharge trough surface of the filter box 19 is slidably connected to the limiting strips 26 on both sides of the cleaning plate 22. The bottom discharge trough surface of the filter box 19 is slidably connected to the cleaning plate 22, and the filter screen 20 is movably connected to one side of the cleaning plate 22.

[0030] In practical use, an air inlet pipe 18 is provided at the air inlet end of the other side of the recycling box 14. A filter box 19 is connected to the other side of the air inlet pipe 18. A filter screen 20 is installed at the intersection of the filter box 19 and the centrifugal fan 21 to intercept the passing debris.

[0031] Preferably, the other side surface of the cleaning plate 22 is connected to a transmission assembly, which includes a toothed plate 23, a transmission gear 24 and a motor 25. The cleaning plate 22 is provided with a toothed plate 23, and the toothed plate 23 is meshed with the transmission gear 24. The transmission gear 24 is threadedly connected to the side wall of the transmission gear 24, and the bottom of the motor 25 is installed on the bottom of the inner wall of the filter box 19.

[0032] In practical use, the motor 25 can be started to rotate, which will cause the transmission gear 24 connected to the transmission end of the motor 25 to rotate together. When the transmission gear 24 rotates, the meshing toothed plate 23 is driven to move downward together. When the toothed plate 23 moves, the limiting strips 26 on both sides of the cleaning plate 22 connected to it slide on the rectangular limiting groove opened at the bottom of the filter box 19, thereby limiting its movement range. The cleaning brush part of the cleaning plate 22 is in close contact with the surface of the filter screen 20, thereby scraping off the debris accumulated on the filter screen 20.

[0033] Preferably, the base frame 6, the recycling bin 14, the limiting frame 15, the sealing strip 16, and the top cover 17 form an interlocking connection structure.

[0034] In practical use, the grooves on the inner wall of the base frame 6 that are adapted to the height of the recycling bin 14 and the top cover 17 are used to fit and clamp the connection between the two, thereby forming a sealed space inside the recycling bin 14 after it is placed.

[0035] Preferably, the filter box 19 is equipped with an "L"-shaped discharge chute near the centrifugal fan 21.

[0036] In practical use, the "L"-shaped discharge chute on the side of the filter box 19 near the centrifugal fan 21 allows for easy adjustment of the toothed plate 23 that abuts against the filter screen 20. The toothed plate 23 scrapes up and down to clean the debris accumulated on the surface of the filter screen 20. The cleaned debris falls into the outlet below and is discharged under gravity.

[0037] Working Principle: During cable processing, the relevant parameters of the cable cutting machine body 1 are adjusted according to the specifications, material, and specific cutting requirements of the cable to be cut. For example, the cutting force is controlled by adjusting the air pressure, and the cutting stroke is adjusted according to the cable diameter. After adjusting the parameters of the cable cutting machine body 1, the machine body 1 is started. The operator must operate the cutting machine smoothly according to the operating procedures, so that the upper cutting blade 4 cuts the cable placed on the lower cutting blade 5 along the predetermined cutting path. At the same time as cutting, the centrifugal fan 21 is started to draw air. The centrifugal fan 21 is existing equipment, model: 4-72. Centrifugal fan 21 is a type of fan with stable performance and high efficiency. Different speeds and power can be selected according to actual needs to meet the collection requirements of debris generated from cable cutting operations of different scales. When centrifugal fan 21 draws air, the filter box 19 and the recovery box 14 connected to it start drawing air together. This causes the dust collection hood 10 connected to the other side of the recovery box 14 to draw air from its front end, thus collecting the cable cutting debris generated by the upper cutter 4 and lower cutter 5 located at the front end of the dust collection hood 10. The collected debris is collected in the recycling box 14 through the connected telescopic pipe 12. At the same time, the air inlet 18 is provided at the air inlet end of the recycling box 14. The other side of the air inlet 18 is connected to the filter box 19. A filter screen 20 is installed at the intersection of the filter box 19 and the centrifugal fan 21 to intercept the passing debris. The filter screen 20 in this design is made of existing material. A suitable fine filter screen 20 can be selected according to the volume of debris produced by the cable cutting machine body 1 to intercept the debris passing through the centrifugal fan 21.

[0038] At this time, the motor 25 can be started to rotate, causing the transmission gear 24 connected to the transmission end of the motor 25 to rotate as well. When the transmission gear 24 rotates, the meshing toothed plate 23 is driven to move downwards. When the toothed plate 23 moves, the limiting strips 26 on both sides of the cleaning plate 22 connected to it slide at the bottom of the filter box 19. At the intersection of the bottom opening of the filter box 19 and the limiting strips 26 on both sides of the cleaning plate 22, the longitudinally opened rectangular groove can limit the movement range of the slidingly connected limiting strips 26 and the cleaning plate 22. The cleaning brush part of the cleaning plate 22 is in close contact with the surface of the filter screen 20, thereby scraping off the debris accumulated on the filter screen 20. The debris scraped off by the toothed plate 23 falls downwards under the action of gravity, thereby preventing the surface of the filter screen 20 from being blocked by the accumulated debris in the air duct between the centrifugal fan 21 and the filter box 19. At the same time, because the filter box 19 is close to the bottom of the centrifugal fan 21, the "L" at the bottom of the filter box 19... The "-shaped" structure facilitates the toothed plate 23 to scrape the debris on the filter screen 20 downwards to the bottom of the air duct of the centrifugal fan 21, so that the scraped debris can be discharged downwards from the outlet at the bottom of the filter box 19 without being attracted by negative pressure.

[0039] Alternatively, the telescopic tube 12 fixed on the other side of the recycling box 14 can be unscrewed, and the recycling box 14 embedded in the inner wall of the base frame 6 can be pulled out. Then, the top cover 17, which is fitted and pressed between the base frame 6 and the recycling box 14 and the sealing strip 16, can be lifted up. This allows the debris collected in the recycling box 14 to be poured out. After pouring, the above operation is repeated to fit and fix the sealing strip 16 and the top cover 17 onto the recycling box 14 respectively. The sealing strip 16 fills the gap between the recycling box 14 and the top cover 17, preventing dust from escaping from the gap. At the same time, the grooves on the inner wall of the base frame 6 that are adapted to the height of the recycling box 14 and the top cover 17 are fitted and clamped to connect the two. This creates a sealed space inside the recycling box 14 after it is placed, which facilitates the collection of debris generated by cutting on the cable cutting machine body 1.

[0040] At the same time, the rectangular plate connected to the front end of the protective cover 8 rotates to remove the cable protected between the protective covers 8. In addition, the protective cover 8 is made of tempered glass, which not only allows the user to easily observe the cable cutting situation on the cable cutting machine body 1, but also can withstand the large impact force generated during cable cutting, effectively blocking debris. Even after long-term use, it is not easy to break or be damaged. At the same time, it has strong chemical stability and will not react with flame-retardant cables and substances in the surrounding environment. It is not affected by flame-retardant cables and can maintain stability for a long time.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
