Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable conveying device. Background Technology

[0002] In the laying, recycling, and processing of cables (including electrical cables, optical cables, etc.), conveying devices are widely used for directional and speed-controlled transport. Existing technologies often employ a pair of parallel conveyor belts or a pair of counter-rotating rollers to clamp the cable from both sides, relying on the static friction between the contact surfaces as the driving force. To prevent the cable from deviating during transport, limiting structures, such as limit baffles or guide wheels, are usually installed on both sides of the conveying path.

[0003] However, in existing conveying methods, the design of a pair of conveyor belts or a pair of rotating rollers is fixed, making it difficult to adjust the distance between them. When conveying thicker cables, the distance between the pair of conveyor belts or rotating rollers is much smaller than the cable diameter, resulting in a large clamping force on the cable, which can cause flattening, excessive deformation, or damage to the internal structure. Conversely, when conveying thinner cables, insufficient clamping force leads to insufficient friction and slippage. Adjusting the distance between the pair of conveyor belts or rotating rollers requires complete disassembly and reassembly, which involves significant effort and time. Furthermore, the existing limiting structure cannot be directly adjusted according to the cable diameter, and replacing the limiting structure is also time-consuming and labor-intensive, impacting work efficiency. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a cable conveying device. The cable is placed on a pair of counter-rotating sleeves and pressed by a spring clamping mechanism. When the spiral protrusions on the pair of sleeves rotate, they generate axial and radial friction on the cable, causing it to be conveyed forward in a centered state. No additional limiting structure is required. The spring clamping mechanism is elastic and adjustable, making it suitable for conveying cables of different diameters, and the conveying is stable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cable conveying device includes a worktable, a drive mechanism, a spring limiting mechanism, and a limiting plate. The worktable has a groove, and a pair of rotating shafts are rotatably mounted on the front and rear ends of the groove. One end of each pair of rotating shafts passes through the end face of the groove and connects to the drive assembly. The drive assembly is located on the end face of the worktable and can drive the pair of rotating shafts to rotate in opposite directions. A rotating roller is mounted on each rotating shaft, and a sleeve is fitted around the rotating roller. The sleeve has helical protrusions, with the helical protrusions on the two sleeves pointing in opposite directions. The height of the sleeve is higher than the upper surface of the worktable. The spring limiting mechanism includes multiple pairs of limiting rods, multiple pairs of compression springs, and multiple pairs of nuts. The multiple pairs of limiting rods are evenly arranged on both sides of the worktable. The limiting plate has limiting holes corresponding to the positions of the limiting rods, and the limiting plate is vertically movable on the multiple pairs of limiting rods through the limiting holes. The upper part of each limiting rod has a thread, and the nut is screwed onto the limiting rod through the thread. The compression spring is fitted onto the limiting rod between the nut and the limiting plate.

[0006] Preferably, the center of the limiting plate is set in an arch shape and the setting direction is along the axis of the cable.

[0007] Preferably, the limiting plate has multiple ball grooves evenly distributed in the arched position, and a buckle plate is fixedly installed at the bottom of the limiting plate. The buckle plate is arched at its center and has multiple ball holes corresponding to the ball grooves in the arched position. Balls are installed in the ball grooves, and the buckle plate fastens and installs the ball in the ball grooves through the ball holes, with a portion of the ball protruding from the bottom of the buckle plate.

[0008] Preferably, the drive mechanism includes a motor with dual output ends, a pair of driving bevel gears and a pair of driven bevel gears. The motor is fixedly mounted on the end face of the worktable, the pair of driving bevel gears are mounted on the two output ends of the motor, and the pair of driven bevel gears are mounted on the through ends of a pair of rotating shafts. The driving bevel gears and driven bevel gears are meshed and connected.

[0010] Preferably, the workbench has a clearance groove located below the cable.

[0011] Preferably, the sleeve and the spiral protrusion are made of rubber.

[0012] This utility model provides a cable conveying device, which has the following beneficial effects: 1. This utility model places the cable on a pair of counter-rotating sleeves and clamps the cable with a spring clamping mechanism. When the spiral protrusions on the pair of sleeves rotate, they generate axial and radial friction on the cable, causing it to be conveyed forward in a centered state. No additional limiting structure is required. The spring clamping mechanism is elastic and adjustable, which can be used to convey cables of different diameters and the conveying is stable. 2. In this utility model, the center position of the limiting plate is set in an arch shape and the setting direction is along the axis of the cable.

[0016] like Figure 1-4As shown, a cable conveying device includes a worktable 6, a drive mechanism, a spring limiting mechanism, and a limiting plate 12. The worktable 6 has a groove 4. A pair of rotating shafts 1 are rotatably mounted on the front and rear ends of the groove 4. One end of each rotating shaft 1 extends through the end face of the groove 4 and connects to the drive assembly. The drive assembly is located on the end face of the worktable 6 and can drive the pair of rotating shafts 1 to rotate in opposite directions. A rotating roller 2 is mounted on each rotating shaft 1. A sleeve 3 is fitted around the rotating roller 2. The sleeve 3 has helical protrusions 5, with the helical protrusions 5 on the two sleeves 3 facing opposite directions. The height of sleeve 3 is higher than the upper surface of worktable 6; the spring limiting mechanism includes multiple pairs of limiting rods 7, multiple pairs of compression springs 10, and multiple pairs of nuts 11. The multiple pairs of limiting rods 7 are evenly arranged on both sides of worktable 6. The limiting plate 12 has limiting holes 9 corresponding to the positions of the limiting rods 7, and the limiting plate 12 is vertically movable on the multiple pairs of limiting rods 7 through the limiting holes 9. The upper part of the limiting rod 7 is threaded, and the nut 11 is screwed onto the limiting rod 7 through the thread. The compression spring 10 is sleeved on the limiting rod 7 between the nut 11 and the limiting plate 12; the middle of the limiting plate 12... The center position is set in an arch shape and the setting direction is along the axis of the cable; the arched position of the limiting plate 12 is evenly provided with multiple ball grooves 14, and a buckle plate 8 is fixedly provided at the bottom of the limiting plate 12. The center position of the buckle plate 8 is set in an arch shape, and the arched position of the buckle plate 8 is provided with multiple ball holes 15 corresponding to the ball grooves 14. A ball bearing 13 is provided in the ball groove 14. The buckle plate 8 fastens and installs the ball bearing 13 in the ball groove 14 through the ball holes 15, and the ball bearing 13 protrudes from the bottom of the buckle plate 8; the driving mechanism includes a dual-output motor 19, a pair of active bevel gears 20 and a pair of Driven bevel gear 17, motor 19 is fixedly mounted on the end face of workbench 6, a pair of driving bevel gears 20 are mounted on the two output ends of motor 19, and a pair of driven bevel gears 17 are mounted on the through ends of a pair of rotating shafts 1. The driving bevel gears 20 and driven bevel gears 17 are meshed and connected. A protective cover 18 is provided on the outside of motor 19, driving bevel gears 20 and driven bevel gears 17. The protective cover 18 is fixedly connected to the end face of workbench 6. A clearance groove 16 is provided on workbench 6 at the position below the cable. The sleeve 3 and the spiral protrusion 5 are made of rubber.

[0017] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-4As can be seen, the workbench 6 of this utility model first adjusts the position of the limiting rod 7 according to the diameter of the cable. This is easy to understand: if the cable is thicker, adjust the nut 11 upwards to move the limiting plate 12 away from the pair of sleeves 3; conversely, if the cable is thinner, adjust the nut 11 downwards to move the limiting plate 12 closer to the pair of sleeves 3. The specific adjustment position can be summarized based on experience, or a scale can be set on the limiting rod 7 corresponding to the cable diameter. Of course, it is necessary to ensure that when the limiting plate 12 presses against the cable, the reaction force of the compression spring 10 can provide sufficient friction for the cable to transmit axially. This is something those skilled in the art can understand. During operation, one end of the cable is inserted between the limiting plate 12 and the pair of sleeves 3. The compression spring 10 is compressed, and the drive mechanism works, causing the pair of rotating shafts 1, the pair of rotating rollers 2, and the sleeves 3 to rotate in opposite directions. Figure 1 For example, the left sleeve 3 rotates clockwise, and the right sleeve 3 rotates counterclockwise. Note the direction of the spiral protrusion 5 on sleeve 3. Figure 2 For example, the cable is inserted from the side furthest from the drive mechanism. This ensures that when the sleeve 3 rotates, the frictional force exerted on the cable by the helical protrusions 5 is both forward and inward. The forward force propels the cable axially forward, while the inward force ensures the cable remains centered and does not deviate, maximizing contact between the helical protrusions 5 and the cable, thus guaranteeing stable transmission. During transmission, the reaction force of the compression spring 10 presses the top of the cable against the limiting plate 12, bringing the cable into contact with the helical protrusions 5 on the pair of sleeves 3 and providing sufficient friction. Since the limiting plate 12 and the cable experience sliding friction, the bottom of the limiting plate 12 can be designed to be smooth. This invention places the cable on a pair of counter-rotating sleeves 3 and presses it against the spring compression mechanism. The rotation of the helical protrusions 5 on the pair of sleeves 3 generates axial and radial friction on the cable, ensuring it is centered and transmitted forward. No additional limiting structure is needed. The spring compression mechanism is elastic and adjustable, suitable for transmitting cables of different diameters, and provides stable transmission.

[0018] The center of the limiting plate 12 is set in an arch shape and the setting direction is along the axis of the cable. The bottom surface of the arched position of the limiting plate 12 is smooth, which can ensure that the cable is pressed tightly without affecting its axial sliding. At the same time, the bottom of the arch can limit the cable and ensure the stability of its axial movement.

[0019] The limiting plate 12 has multiple ball grooves 14 evenly distributed in the arched position, and the buckle plate 8 has multiple ball holes 15 corresponding to the ball grooves 14 in the arched position. The buckle plate 8 fastens the ball 13 into the ball groove 14 through the ball hole 15. The ball 13 protrudes from the bottom of the buckle plate 8. The ball 13 presses the cable tightly and changes the sliding friction with the limiting plate 12 to rolling friction, reducing the friction force and making the axial movement of the cable smoother.

[0020] The drive mechanism includes a dual-output motor 19, a pair of driving bevel gears 20, and a pair of driven bevel gears 17. The motor 19 is fixedly mounted on the end face of the worktable 6. The pair of driving bevel gears 20 are located on the two output ends of the motor 19, and the pair of driven bevel gears 17 are located at the through ends of a pair of rotating shafts 1. The driving bevel gears 20 and driven bevel gears 17 are meshed together. The structure is simple, easy to repair and maintain, and the gear transmission is stable, ensuring the synchronicity of the rotation of the pair of rotating shafts 1 as much as possible, and has high transmission efficiency. In addition, a protective cover 18 is provided outside the motor 19, driving bevel gears 20, and driven bevel gears 17. The protective cover 18 is fixedly connected to the end face of the worktable 6 to ensure the safety of the drive mechanism during operation.

[0021] The workbench 6 has a clearance groove 16 located below the cable to prevent the cable from contacting the surface of the workbench 6.

[0022] Among them, the sleeve 3 and the spiral protrusion 5 are made of rubber, which not only increases the friction between them and the cable, but also reduces the squeezing damage to the cable.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
