Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a device for sanding the surface of cable sheaths. Background Technology

[0002] In cable production and processing, outer sheath sanding is a key process to improve the anti-slip and anti-fouling properties of cables. However, current traditional sanding equipment has many technical shortcomings, making it difficult to meet the needs of efficient and high-quality production. Some equipment lacks an orderly cable collection structure, and the sanded cables are prone to pile up messily, requiring extra time to sort them. Moreover, cable transportation mostly relies on manual pushing or pulling, which not only increases labor costs but also affects the sanding efficiency and consistency due to unstable pushing speed, thus reducing production efficiency. Furthermore, the large amount of dust generated during grinding lacks an effective collection mechanism and tends to diffuse directly into the working environment, which not only harms the respiratory health of operators but also easily adheres to the surface of cables, affecting product quality. The grinding components of traditional equipment are mostly fixed structures that can only be used with cables of a single diameter. When dealing with cables of different specifications, it is necessary to frequently disassemble and replace components, which is not only time-consuming and labor-intensive but also prone to dead corners where grinding is not done properly due to poor contact between the grinding surface and the cable, resulting in uneven sanding texture. These problems seriously restrict the optimization and upgrading of the cable sanding process. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cable sheath surface sanding treatment device. This device uses a rotating elastic sanding plate to avoid sanding dead angles. After the fan is started, a negative pressure space is formed in the inner cavity, which, together with the up-and-down movement of the dust brush, prevents dust from spreading into the air.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A cable sheath surface sanding treatment device includes a support frame, a guide table movably connected to the front end of the support frame, a limit support fixedly connected to the upper end of the guide table, an inner cavity provided inside the support frame, a drive gear rotatably connected to the upper inner side of the inner cavity, a dust sweeping component provided at the rear end of the drive gear, a driven gear meshing with the lower end of the drive gear, a reducing rotating ring provided inside the driven gear, the front and rear ends of the reducing rotating ring rotatably connected inside the support frame, a grinding plate installed inside the reducing rotating ring, a drawer provided at the lower end of the support frame, a dust filter plate fixedly connected inside the left end of the support frame, and a fan fixedly connected to the left end of the support frame outside the dust filter plate.

[0005] Furthermore, the inner diameter of the front end of the shrinkage rotating ring is smaller than the inner diameter of the rear end.

[0006] Furthermore, the dust sweeping assembly includes a cam support fixedly connected to the rear end of the drive gear, a support arm is mounted on the lower end of the cam support, and a dust sweeping brush is mounted on the lower end of the support arm.

[0007] Furthermore, a limiting slide rail is fixedly connected to the rear end of the upper part of the inner cavity, and the rear end of the support arm is slidably connected to the inner side of the limiting slide rail.

[0008] Furthermore, a drive motor is fixedly connected inside the upper end of the support frame, and the drive end of the drive motor is fixedly connected to the front end of the drive gear.

[0009] Furthermore, a wire support is provided on the rear side of the support frame, and a take-up roller is provided on the rear side of the wire support.

[0010] Furthermore, a path shaft is installed at the upper end of the conductor bracket, and a guide arm is slidably connected to the periphery of the path shaft.

[0011] Furthermore, a wire feeding roller is provided at the front end of the guide table.

[0012] This utility model has the following beneficial effects: In this invention, the elastic grinding plate rotates and grinds the cable. After being placed in the grinding plate, it automatically fits tightly against the outer wall of the cable, which can accommodate cables of different diameters. It eliminates the need to frequently replace the grinding parts and avoids grinding dead corners. The movable guide table opens and supports the cable on the ground, making it convenient to place the cable and guiding the cable into the grinding area.

[0013] In this invention, the cable is automatically pulled by a motor driven by the take-up roller, eliminating the need for manual pushing or pulling of the cable and reducing labor costs. After the fan is started, the device creates a negative pressure space in the inner cavity. With the up-and-down movement of the dust brush, the dust generated during grinding can be sucked into the inner cavity in real time and eventually fall into the drawer, preventing the dust from spreading into the air.

Detailed Implementation

[0016] 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.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a cable sheath surface sanding treatment device, including a support frame 1, a guide table 4 movably connected to the front end of the support frame 1, a limit support 3 fixedly connected to the upper end of the guide table 4, an inner cavity 2 provided inside the support frame 1, a drive gear 10 rotatably connected to the upper inner side of the inner cavity 2, a cam support 9 fixedly connected to the rear end of the drive gear 10, a support arm 8 installed at the lower end of the cam support 9, a dust brush 15 installed at the lower end of the support arm 8, a driven gear 14 meshing with the lower end of the drive gear 10, a reducing rotating ring 12 provided inside the driven gear 14, the front and rear ends of the reducing rotating ring 12 rotatably connected to the inside of the support frame 1, a grinding plate 13 installed inside the reducing rotating ring 12, a drawer 7 provided at the lower end of the support frame 1, a dust filter plate 5 fixedly connected inside the left end of the support frame 1, and a fan 6 fixedly connected to the left end of the support frame 1 outside the dust filter plate 5.

[0018] When it is necessary to polish the cable sheath and perform a sanding treatment on the cable sheath, open the guide table 4 and support it on the ground. Place the pay-off roller 16 in front of the guide table 4, place the wire support 17 behind the support frame 1, and place the take-up roller 18 behind the wire support 17. When placing the take-up roller 18, place it correspondingly to the wire support 17. Place the cable end around the pay-off roller 16 along the limiting support 3 into the inside of the polishing plate 13. Sandpaper is installed on the inside of the polishing plate 13. The polishing plate 13 is an elastic device, slightly bent when no cable is placed. When placing the cable, the polishing plate 13 can be opened. After the cable is placed, the tension on the inside of the polishing plate 13 is released, and the polishing plate 13 springs tightly against the outer wall of the cable. Open the shrinking rotating ring 12, and the drive end of the shrinking rotating ring 12 rotates, driving the drive gear 10 to rotate, causing the driven gear 14 meshing with the drive gear 10 to rotate, driving the shrinking rotating ring 12 to rotate. At the same time, the polishing plate 13 rotates, starting the process. The fan 6 creates a negative pressure space in the inner cavity 2, filtering and extracting dust from the air through the dust filter plate 5. The dust swept by the dust brush 15 is then sucked into the inner cavity 2 and falls into the drawer 7, slowly pushing the cable forward. The cable end passes through the dust brush 15 to remove the dust generated on the surface. The drive gear 10 rotates, causing the cam support 9 to rotate. At the same time, the upper end of the support arm 8 moves with the cam support 9. The rear end of the support arm 8 is equipped with a fixed-path slide bar, which slides inside the limit slide rail 19, allowing the support arm 8 to move up and down at the upper end of the inner cavity 2. This causes the dust brush 15 to move up and down around the cable to remove dust. The elastic grinding plate rotates and grinds 13. After placement, it can automatically fit tightly against the outer wall of the cable, adapting to cables of different diameters. It eliminates the need for frequent replacement of grinding parts and avoids grinding dead corners. The movable guide table 4 opens and supports the cable on the ground, facilitating cable placement and guiding the cable into the grinding area.

[0019] Reference Figures 1-3 The inner diameter of the front end of the reducing rotating ring 12 is smaller than that of the rear end. The upper rear end of the inner cavity 2 is fixedly connected to the limiting slide rail 19. The rear end of the support arm 8 is slidably connected to the inner side of the limiting slide rail 19. The upper end of the support frame 1 is fixedly connected to the drive motor 11. The drive end of the drive motor 11 is fixedly connected to the front end of the drive gear 10. The support frame 1 is provided with a wire support 17. The wire support 17 is provided with a take-up roller 18. The upper end of the wire support 17 is equipped with a path shaft 20. The path shaft 20 is slidably connected to the periphery of the path shaft 20. The guide arm 21 is slidably connected to the outer periphery of the guide table 4. The front end of the guide table 4 is provided with a pay-off roller 16.

[0020] The cable slides out through the guide outlet at the rear end of the support frame 1, guiding the cable end to the upper end of the guide arm 21, and then fixing it to the outer periphery of the take-up roller 18. The motor at the end of the take-up roller 18 is started, pulling the cable backward. Before the cable winds around the outer periphery of the take-up roller 18, it passes through the guide arm 21. When the cable is pulled, the guide arm 21 moves left and right around the outer periphery of the path shaft 20. The guide device at the lower inner side of the guide arm 21 slides around the outer periphery of the path shaft 20, so that the cable winds around the outer periphery of the take-up roller 18 in an orderly manner. During the sanding process, the larger diameter end of the shrinking rotating ring 12 faces the dust brush 15, and dust accumulates inside the shrinking rotating ring 12. When the cable is sanded, the inner circumference of the rotating ring 12 can be reduced to wait for the inclined plane to fall into the drawer 7. After the entire cable is sanded at the wire feeding roller 16, the fan 6 can be turned off, and the drawer 7 can be taken out to clean the accumulated dust. When the sanding effect decreases, the guide table 4 can be folded and retracted, the sanding plate 13 can be opened, and the sandpaper or sanding plate 13 can be replaced. The motor set in the take-up roller 18 automatically pulls the cable to move, eliminating the need for manual pushing or pulling of the cable, thus reducing labor costs. After the equipment is started by the fan 6, a negative pressure space is formed in the inner cavity 2. With the up and down movement of the dust brush 15, the dust generated by sanding can be sucked into the inner cavity 2 in real time and finally fall into the drawer 7, preventing the dust from spreading into the air.

[0021] Working principle: When it is necessary to polish the cable sheath and perform sanding treatment on the cable sheath, open the guide table 4 and support it on the ground. Place the pay-off roller 16 in front of the guide table 4, place the wire support 17 behind the support frame 1, and place the take-up roller 18 behind the wire support 17. When placing the take-up roller 18, place it correspondingly to the wire support 17. Place the cable end around the pay-off roller 16 into the inner side of the polishing plate 13 along the limiting support 3. Open the shrinkage rotating ring 12. The driving end of the shrinkage rotating ring 12 rotates, driving the driving gear 10 to rotate, causing the driven gear 14 meshing with the driving gear 10 to rotate, driving the shrinkage roller 16 to rotate. The rotating ring 12 rotates, and the grinding plate 13 rotates simultaneously. The fan 6 is started, and dust in the air is filtered and extracted through the dust filter plate 5. The cable is slowly pushed forward, and the dust on the surface of the cable end is swept away by the dust brush 15. The cable slides out through the guide outlet set at the rear end of the support frame 1, and the cable end is guided to the upper end of the guide arm 21 and then fixed to the outside of the take-up roller 18. The motor set at the end of the take-up roller 18 is started, and the cable is pulled backward, so that the sanded cable is orderly wound around the outside of the take-up roller 18. After the entire circle of cable at the unwind roller 16 is sanded, the fan 6 is turned off, and the drawer 7 can be taken out to clean the accumulated dust.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
