Description

Technical Field

[0001] This utility model relates to the technical field of cable forming, and in particular to a wire and cable roll forming machine. Background Technology

[0002] During cable production, cables are extruded into strips, but the extruded cable shape cannot achieve a perfectly round shape. Therefore, roll forming is necessary. Chinese utility model patent CN220106118U discloses a wire and cable roll forming machine. This machine uses a cleaning device to clean the pressure rollers, reducing the impact of outer sheath debris on the cable rolling process; a recycling device to collect the debris removed by the cleaning device, reducing the impact of debris accumulation on the operating environment and improving the practicality of the device; a cooling device to cool the rolled cable, quickly fixing its shape and preventing deformation of the outer sheath due to impacts during subsequent processing; a water collection device to collect wastewater generated during the cooling process and screen out debris in the water; and a water removal device to clean and dry water droplets adhering to the cable, preventing water droplets from affecting subsequent processing and storage.

[0003] However, the existing roll forming machine mentioned above cannot coat the surface of the air-dried wires and cables with protective powder to reduce scratches caused by friction between the wires and cables, so it needs to be improved. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wire and cable roll forming machine that can coat the outer wall of the insulation layer of wires and cables with protective powder, reduce friction and scratches, improve the quality of wires and cables, and has good practicality.

[0005] This utility model discloses a wire and cable roll forming machine, comprising a frame, a roller frame, two rollers, and a spraying mechanism. The roller frame is mounted on the frame, and the two rollers are mounted opposite each other on the roller frame. The two rollers roll-form the wires and cables. The spraying mechanism is mounted on the frame and located to the right of the roller frame. The spraying mechanism is used to spray and cool the wires and cables. The machine also includes a powder tank, a feeding hopper, and a distribution pipe. The powder tank is mounted on the frame and located to the right of the spraying mechanism. The powder tank has a powder chamber inside. The feeding hopper is mounted on the powder tank and communicates with the powder chamber. The powder tank has a through hole, and the distribution pipe is installed through the through hole of the powder tank. In this system, the feeding pipe is equipped with multiple powder leakage holes, which are connected to the powder chamber of the powder tank. Protective powder, such as talc powder, is added to the powder chamber of the powder tank to protect the insulation layer of the wires and cables through the feeding hopper. During operation, the wires and cables pass through two rollers for roll forming and are conveyed to the right. After roll forming, the wires and cables are sprayed and cooled by a spraying mechanism. After being cooled by spraying, the wires and cables pass through the feeding pipe and are conveyed backward. The protective powder in the powder tank is coated onto the outer wall of the insulation layer of the wires and cables through the multiple powder leakage holes of the feeding pipe, thereby reducing scratches caused by mutual friction between the wires and cables, which is beneficial to improving the quality of the wires and cables and has good practicality.

[0006] Preferably, the assembly also includes a slide rail, a slider, a tension spring, a motor, and two clamping rods. The slide rail is mounted on the frame, the slider is slidably mounted on the slide rail, the powder tank is mounted on the slider, one end of the tension spring is connected to the slide rail, and the other end of the tension spring is connected to the slider. The motor is mounted on the powder tank via a bracket, and the motor's output shaft is fitted with two clamping rods, which are located on both sides of the wire and cable. The tension of the tension spring pulls the slider towards the left end of the slide rail, and the rotation of the motor's output shaft causes the two clamping rods to clamp onto the two side walls of the wire and cable, thus allowing the wire and cable to be transported backward. When the powder is fed, it moves synchronously with the powder tank and stretches the tension spring to store energy. After the tension spring moves a certain distance, the output shaft of the motor rotates, causing the two clamping rods to disengage from the side walls of the wire and cable. At this time, the stored energy of the tension spring is released, pulling the slider to the left end of the slide rail, causing the powder tank to move quickly along the cable. This allows the powder tank to quickly coat the wire and cable with protective powder through the distribution tube. The above actions are repeated, causing the powder tank to move back and forth to coat the wire and cable. When the powder tank moves back and forth, the protective powder in its powder chamber shakes, preventing the protective powder from caking.

[0007] Preferably, it also includes a limit switch, which is installed on the slide rail and located on the right side of the slider. The limit switch is electrically connected to the motor controller. When the slider moves to the right along the slide rail and contacts the limit switch, the limit switch sends a signal to the motor controller, causing the motor to start reversing, causing the two clamping rods to disengage from the outer wall of the wire and cable, thereby realizing the clamping and release of the wire and cable and improving the degree of automation.

[0008] Preferably, it also includes a powder receiving trough, which is mounted on the frame and located below the slide rail; excess protective powder on the wires and cables falls into the powder receiving trough for collection, reducing waste.

[0009] Preferably, it also includes a fan, which is mounted on the frame and located on the right side of the spraying mechanism; the fan dries the wires and cables that have been sprayed and cooled by the spraying mechanism, so that the wires and cables dry faster.

[0010] Preferably, the roller frame includes a column, two swing arms, two torsion springs, two shafts, two limiting discs, and two bearing components. The column is mounted on the machine frame. The left ends of the two swing arms are rotatably connected to the column. The two torsion springs elastically connect the two swing arms to the column. Shafts are mounted on the right ends of the two swing arms. The two limiting discs are concentrically connected to the outer rings of the two bearing components. The inner rings of the two bearing components are rotatably mounted on the two shafts. Keys are provided on the outer walls of the outer rings of the two bearing components. Keyways matching the keys are provided on the walls of the central holes of the two rollers. The two rollers are mounted on the outer rings of the two bearing components through the central holes. The two rollers are mounted on the outer rings of the two bearing components and are connected by transmission through the keys and keyways. The two limiting discs limit the installation position of the two rollers. The elastic force of the two torsion springs brings the right ends of the two swing arms closer together, thereby pressing the two rollers into close contact to roll-form the wires and cables. The elastic force of the two torsion springs ensures the rolling forming force of the two rollers on the wires and cables, improving practicality.

[0011] Preferably, the assembly also includes two strong magnetic blocks (first type), two swing arms, two strong magnetic blocks (second type), and two arc-shaped rods. The two strong magnetic blocks (first type) are respectively mounted on the end faces of the two rollers. The inner ends of the two swing arms are rotatably mounted on two limiting discs. Strong magnetic blocks (second type) are mounted on the outer ends of both swing arms, and are attracted to and connected to the two strong magnetic blocks (first type). Arc-shaped rods are mounted on both swing arms, and are slidably mounted in the arc-shaped grooves on the two limiting discs. After the rollers are installed on the bearing assembly, strong magnetic blocks (first type) and strong magnetic blocks (second type) are attracted to each other, thus enabling a quick and reliable connection between the rollers and the bearing assembly. When the rollers need to be replaced, the arc-shaped rods are moved along the arc-shaped grooves of the limiting discs, causing the swing arms to rotate and disengage the strong magnetic blocks (second type) from the strong magnetic blocks (first type). This facilitates the removal of the rollers from the bearing assembly, making the installation and removal of the rollers convenient.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: protective powder, such as talc powder, is added to the powder chamber of the powder tank through the feeding hopper to protect the insulation layer of the wire and cable; during operation, the wire and cable pass through two rollers for roll forming and is conveyed to the right. After roll forming, the wire and cable are sprayed and cooled by the spraying mechanism. After being cooled by the spraying mechanism, the wire and cable pass through the feeding pipe and is conveyed backward. The protective powder in the powder tank is coated onto the outer wall of the insulation layer of the wire and cable through multiple powder leakage holes in the feeding pipe, thereby reducing scratches caused by mutual friction between the wires and cables, which is beneficial to improving the quality of the wires and cables and has good practicality.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 3As shown, a wire and cable roll forming machine includes a frame 1, a roller frame 2, two rollers 3, and a spraying mechanism 4. The roller frame 2 is mounted on the frame 1, and the two rollers 3 are mounted opposite each other on the roller frame 2. The two rollers 3 roll-form the wire and cable. The spraying mechanism 4 is mounted on the frame 1 and located to the right of the roller frame 2. The spraying mechanism 4 is used to spray and cool the wire and cable. The machine also includes a powder tank 5, a feeding hopper 6, and a feeding pipe 7. The powder tank 5 is mounted on the frame 1 and located to the right of the spraying mechanism 4. On the right side of the spraying mechanism 4, a powder chamber is set inside the powder tank 5. A feeding hopper 6 is installed on the powder tank 5 and communicates with the powder chamber. The powder tank 5 is provided with a through hole. A distribution pipe 7 is installed in the through hole of the powder tank 5 and is provided with multiple powder leakage holes. The powder leakage holes communicate with the powder chamber of the powder tank 5. It also includes a powder receiving trough 14, which is installed on the frame 1 and is located below the slide rail 8. It also includes a fan 15, which is installed on the frame 1 and is located on the right side of the spraying mechanism 4.

[0023] Protective powder, such as talc, is added to the powder chamber of the powder tank 5 through the feeding hopper 6 to protect the insulation layer of the wires and cables. During operation, the wires and cables pass through two rollers 3 for roll forming and are conveyed to the right. After roll forming, the wires and cables are sprayed and cooled by the spraying mechanism 4. The fan 15 dries the wires and cables after they have been sprayed and cooled by the spraying mechanism 4, making the wires and cables dry faster. After drying, the wires and cables pass through the cloth pipe 7 and are conveyed backward. The protective powder in the powder tank 5 is coated onto the outer wall of the insulation layer of the wires and cables through multiple powder leakage holes in the cloth pipe 7, thereby reducing scratches caused by mutual friction between the wires and cables and improving the quality of the wires and cables. Excess protective powder on the wires and cables falls into the powder receiving trough 14 for collection, reducing waste.

[0024] Example 2

[0025] like Figures 1 to 4 As shown, based on Embodiment 1, it also includes a slide rail 8, a slider 9, a tension spring 10, a motor 11, and two clamping rods 12. The slide rail 8 is mounted on the frame 1, the slider 9 is slidably mounted on the slide rail 8, the powder tank 5 is mounted on the slider 9, one end of the tension spring 10 is connected to the slide rail 8, and the other end of the tension spring 10 is connected to the slider 9. The motor 11 is mounted on the powder tank 5 through a bracket, and the output shaft of the motor 11 is equipped with two clamping rods 12, which are located on both sides of the wire and cable respectively. It also includes a limit switch 13, which is mounted on the slide rail 8 and located on the right side of the slider 9.

[0026] The tension of the tension spring 10 pulls the slider 9 toward the left end of the slide rail 8. The output shaft of the motor 11 rotates, causing the two clamping rods 12 to clamp onto the two side walls of the wire and cable respectively. This causes the powder tank 5 to move synchronously as the wire and cable is conveyed backward, and the tension spring 10 is stretched and stored. After the tension spring 10 moves a certain distance, the limit switch 13 is electrically connected to the controller of the motor 11. When the slider 9 moves to the right along the slide rail 8 and contacts the limit switch 13, the limit switch 13 sends a signal to the controller of the motor 11, causing the motor 11 to start reversing. The output shaft of the motor 11 rotates, causing the two clamping rods 12 to disengage from the two side walls of the wire and cable. At this time, the stored force of the tension spring 10 is released, pulling the slider 9 toward the left end of the slide rail 8, causing the powder tank 5 to move quickly along the cable. This allows the powder tank 5 to quickly coat the wire and cable with protective powder through the distribution tube 7. The above actions are repeated, causing the powder tank 5 to move back and forth to coat the wire and cable. When the powder tank 5 moves back and forth, the protective powder in its powder chamber shakes, preventing the protective powder from caking.

[0027] Example 3

[0028] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, based on Embodiment 1, the roller frame 2 includes a column 16, two swing arms 17, two torsion springs 18, two shafts 19, two limiting discs 20, and two bearing components 21. The column 16 is mounted on the frame 1. The left ends of the two swing arms 17 are rotatably connected to the column 16. The two torsion springs 18 respectively elastically connect the two swing arms 17 to the column 16. The right ends of the two swing arms 17 are each mounted with a shaft 19. The two limiting discs 20 are concentrically connected to the outer rings of the two bearing components 21. The inner rings of the two bearing components 21 are rotatably mounted on the two shafts 19. Keys are provided on the outer walls of the outer rings of the two bearing components 21. The centers of the two rollers 3 are... The bore walls are provided with keyways that match the keys. The two rollers 3 are respectively fitted onto the outer rings of the two bearing components 21 through the central holes. It also includes two strong magnetic blocks 22, two rocker arms 23, two strong magnetic blocks 24, and two arc rods 25. The two strong magnetic blocks 22 are respectively installed on the end faces of the two rollers 3. The inner ends of the two rocker arms 23 are respectively rotatably installed on the two limiting disks 20. The outer ends of the two rocker arms 23 are each equipped with a strong magnetic block 24. The two strong magnetic blocks 24 are respectively attracted and connected to the two strong magnetic blocks 22. Arc rods 25 are installed on the two rocker arms 23. The two arc rods 25 are respectively slidably installed in the arc grooves on the two limiting disks 20.

[0029] After the roller 3 is installed on the bearing component 21, the strong magnetic block 1 22 and the strong magnetic block 24 are attracted and connected, so that the roller 3 is quickly and reliably connected to the bearing component 21. When the roller 3 needs to be replaced, the arc rod 25 is moved along the arc groove of the limiting plate 20, so that the arc rod 25 drives the swing rod 23 to rotate, so that the swing rod 23 drives the strong magnetic block 24 to disengage from the strong magnetic block 1 22. At this time, it is convenient to remove the roller 3 from the bearing component 21, which facilitates the installation and removal of the roller 3. The two rollers 3 are respectively fitted on the outer ring of the two bearing components 21 and are connected by key and keyway. The two limiting plates 20 limit the installation position of the two rollers 3. The elastic force of the two torsion springs 18 brings the right end of the two swing arms 17 closer, so that the two rollers 3 press against each other to roll and form the wires and cables. The elastic force of the two torsion springs 18 ensures the rolling and forming force of the two rollers 3 on the wires and cables.

[0030] like Figures 1 to 6 As shown, this utility model discloses a wire and cable roll forming machine. During operation, the wire and cable first pass through two rollers 3 for roll forming and are conveyed to the right. The elasticity of two torsion springs 18 ensures the roll forming force of the two rollers 3 on the wire and cable. After roll forming, the wire and cable are cooled by a spraying mechanism 4. The cooled wire and cable then passes through a feeding pipe 7 and is conveyed backward. The output shaft of the motor 11 rotates, driving two clamping rods 12 to clamp the two side walls of the wire and cable respectively. This causes the powder tank 5 to move synchronously as the wire and cable are conveyed backward, pulling the tension springs 10. When the tension spring 10 moves a certain distance, the output shaft of the motor 11 rotates, causing the two clamping rods 12 to disengage from the side walls of the wire and cable. At this time, the tension spring 10 releases its stored force, pulling the slider 9 towards the left end of the slide rail 8, causing the powder tank 5 to move quickly along the cable. This allows the powder tank 5 to quickly coat the wire and cable with protective powder through the distribution tube 7. The above action is repeated, causing the powder tank 5 to move back and forth, coating the wire and cable through the distribution tube 7. Finally, when the powder tank 5 moves back and forth, the protective powder in its powder chamber shakes, preventing the protective powder from caking and reducing scratches caused by friction between the wire and cable.

[0031] The main functions achieved by this utility model are:

[0032] 1. It can coat the outer wall of the insulation layer of wires and cables with protective powder, reduce friction and scratches, and help improve the quality of wires and cables;

[0033] 2. Prevent the protective powder from caking by moving the powder container 5 back and forth;

[0034] 3. It can quickly install and remove the roller 3, improving work efficiency.

[0035] The wire and cable roll forming machine of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The roller frame 2, roller 3, spraying mechanism 4, powder tank 5, feeding hopper 6, slide rail 8, slider 9, tension spring 10, motor 11, limit switch 13, fan 15, torsion spring 18, shaft 19, bearing component 21, strong magnetic block 1 22, and strong magnetic block 24 are all purchased from the market.
