Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire feeding mechanisms, specifically to a wire feeding mechanism for the production of PVC electronic wires. Background Technology
[0002] Wire feeding mechanisms, as devices used for placing and unwinding wires, play a crucial role in various industries such as wire and cable, textiles, and packaging. Especially in the production of PVC electronic wires, the feeding mechanism not only ensures the smooth release of the wire but also guarantees wire quality and efficiency during the production process. PVC electronic wires are widely used in the internal wiring of general electronic and electrical equipment, including but not limited to household appliances, lighting fixtures, electronic equipment, instruments, electronic toys, electrical equipment, security equipment, and temperature sensors. The lead-out connecting wires in these devices mostly use PVC electronic wires due to their excellent insulation and temperature resistance, thus ensuring the stable operation of the equipment.
[0003] Existing electronic wire unwinding mechanisms typically consist of a frame, transmission system, tensioning device, and reel. The basic principle of the unwinding mechanism is that the transmission mechanism drives the wire to unwind and be released from the reel, while the tensioning device maintains stable wire tension. In practical applications, the unwinding motor is connected to the unwinding spool via an unwinding clutch, and the guiding mechanism includes a U-shaped grooved wheel, which works with the unwinding spool to perform both take-up and unwinding operations. Both take-up and unwinding of the cable require passage through the U-shaped grooved wheel in the guiding structure. During take-up, friction provides tension, and during unwinding, friction pulls the cable out.
[0004] However, while existing electronic wire feeding mechanisms meet production needs to a certain extent, some shortcomings remain. In the production of PVC electronic wires, the arrangement and tension control of the wires are crucial to production efficiency and product quality. However, the existing feeding mechanisms are relatively simple, leading to wires being pulled too tight or too loose, thus affecting the performance and lifespan of the electronic wires. Furthermore, the existing feeding drive is a stepper drive, which is prone to slack when the wire is stopped after feeding. This slack can cause the wires to become tangled and shift when winding into the guide structure, affecting the continuity of feeding, leading to frequent downtime, and severely impacting production smoothness and efficiency. Utility Model Content
[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a wire feeding mechanism for PVC electronic wire production, so as to solve the technical problem in the background art that the wires are prone to slack after the wire feeding stops, which leads to the wires being easily tangled and displaced, thereby affecting the continuity of wire feeding and production efficiency.
[0006] The objective of this utility model is achieved through the following means:
[0007] A wire feeding mechanism for producing PVC electronic wires includes a support platform and a control box mounted on the support platform. A wire feeding frame is vertically mounted on the support platform. A rotatable wire feeding shaft is connected to the side of the wire feeding frame. A material tray for holding the wire roll is sleeved on the wire feeding shaft, and a wire feeding drive motor for driving the wire feeding shaft to rotate and feed the wire is connected to one end of the wire feeding shaft. A guide component for guiding the electronic wire for transmission is provided on the support platform. A traction roller for pulling the electronic wire for transmission and a pressing roller for pressing the electronic wire against the traction roller are provided on the side of the control box. A traction drive motor for driving the traction roller to rotate is provided on the side of the control box. A wire pulling cylinder is connected to the side of the control box through a support plate. The telescopic end of the wire pulling cylinder extends towards the traction roller and is connected to a wire pulling pressure plate, so that the telescopic end of the wire pulling cylinder drives the wire pulling pressure plate to press down for stretching the electronic wire. A clamping cylinder for holding the electronic wire is provided on the side of the control box.
[0008] Furthermore, as described above, the material tray is sleeved on the wire feeding shaft and is connected and clamped from one end of the wire feeding shaft by a clamping component.
[0009] The material tray is used to mount the wound electronic wire, which is then mounted on the wire feeding shaft. The wire feeding is driven by the wire feeding drive motor to rotate and feed the wire.
[0010] Further as described above, the guiding assembly includes a guide rod, a first guide roller, a second guide roller, and a sliding seat mounted on the guide rod. The first guide roller is mounted on the guide rod via a connector and is located above the second guide roller. The second guide roller is mounted on the sliding seat, which can slide along the guide rod to drive the second guide roller to move up and down.
[0011] The support platform is equipped with a testing device for testing wires.
[0012] The second guide roller is movably mounted on the guide rod under the action of gravity. When the wire feeding shaft rotates slowly, the wire will pull the second guide roller closer to the first guide roller. Conversely, when the wire feeding shaft rotates quickly, the second guide roller will press the wire downward under the action of gravity to ensure the tension of the wire.
[0013] Furthermore, as described above, the outer surfaces of the first guide roller and the second guide roller each have two or more guide rails, which are spaced apart along the axial direction of the first guide roller or the second guide roller.
[0014] By using spaced guide rails, the guiding effect on wire winding is improved, thereby preventing the wire from tangling or shifting due to slack, and thus improving the continuity and stability of wire laying.
[0015] Furthermore, as described above, the pressing roller is rotatably mounted on the side of the control box via a connecting shaft. The side of the control box is provided with a mounting plate for mounting the connecting shaft, and the outer surface of the pressing roller is in tangential contact with the outer surface of the traction roller.
[0016] Driven by a traction drive motor, the traction rollers can pull and convey the wire, while the pressure rollers can press the wire against the traction rollers, thus ensuring the stability and continuity of the wire feeding and conveying through the traction rollers and pressure rollers.
[0017] Furthermore, as described above, the side of the control box is provided with a guide plate for mates with the pull-wire pressure plate. The inner side of the guide plate is provided with a guide groove that matches the pull-wire pressure plate, so that the pull-wire cylinder can drive the pull-wire pressure plate to slide along the guide groove of the guide plate. The guide plate is located at the wire outlet end of the traction roller and the pressure roller.
[0018] By setting a guide plate and a guide groove on the guide plate, the stability of the lifting and lowering movement of the wire pressure plate is improved.
[0019] Furthermore, as described above, the end of the wire-pulling pressure plate is arc-shaped or connected to a wire-pulling roller.
[0020] By using an arc-shaped setting or a pressure roller, the wire is protected against compression damage caused by downward pressure.
[0021] Optionally, the end of the wire clamping plate is bonded with a silicone pad for pressing against the wire, thereby providing protection against the downward pressure on the wire and reducing the damage caused by the downward pressure.
[0022] Furthermore, as described above, a metal proximity sensor for detecting electronic wires is connected to the side of the control box via a bracket.
[0023] The wire is pressed down to a certain distance by a metal proximity sensor and then stopped. At the same time, the wire-pulling cylinder contracts synchronously as the wire continues to be fed, thereby further ensuring tension control of the wire release.
[0024] The beneficial effects of this utility model are as follows: The rotation of the wire feeding drive motor causes the wire feeding shaft to automatically rotate and feed the wound electronic wire. The guide component effectively guides the transmission path of the electronic wire, ensuring the stability and accuracy of the electronic wire during the production process and avoiding production failures caused by wire tangles. The combination of traction rollers and pressure rollers can stably pull the electronic wire for transmission. At the same time, the pressure rollers press the electronic wire against the traction rollers, increasing the friction during transmission and preventing the electronic wire from slipping or falling off. Driven by the traction drive motor, the traction rollers can rotate continuously and stably, thereby pulling the wire and ensuring continuous transmission of the electronic wire. The extension end of the wire pulling cylinder drives the wire pulling plate to press down, stretching the electronic wire and ensuring the tension of the electronic wire in the slack state when transmission stops, avoiding loosening and tangling due to slack. When it is necessary to stably fix the electronic wire, the extension end of the clamping cylinder is used to hold the wire pressed down by the wire pulling plate, preventing displacement due to external interference, thus improving the stability and reliability of the production process.

Detailed Implementation
[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0031] In this embodiment, refer to Figures 1-4The present invention relates to a wire feeding mechanism for producing PVC electronic wire, comprising a support platform 1 and a control box 2 mounted on the support platform 1. A wire feeding frame 3 is vertically mounted on the support platform 1. A rotatable wire feeding shaft 4 is connected to the side of the wire feeding frame 3. A material tray 5 for holding the wire roll is axially sleeved on the wire feeding shaft 4. A wire feeding drive motor 6 for driving the wire feeding shaft 4 to rotate and feed the wire is connected to one end of the wire feeding shaft 4. A guide component 7 for guiding the electronic wire for transmission is provided on the top of the support platform 1. A useful guide component 7 is provided on the side of the control box 2. The control box 2 includes a traction roller 8 for transmitting the electronic wire and a pressing roller 9 for pressing the electronic wire against the traction roller 8. A traction drive motor 10 for driving the traction roller 8 to rotate is provided on the side of the control box 2. A wire-pulling cylinder 12 is connected to the side of the control box 2 via a support plate 11. The telescopic end of the wire-pulling cylinder 12 extends toward the traction roller 8 and is connected to a wire-pulling pressure plate 13, so that the telescopic end of the wire-pulling cylinder 12 drives the wire-pulling pressure plate 13 to press down for stretching the electronic wire. A clamping cylinder 14 for holding the electronic wire is provided on the side of the control box 2.
[0032] The feed tray 5 is sleeved on the pay-off shaft 4 and is connected and secured to one end of the pay-off shaft 4 by a clamping component. The feed tray 5 is used to mount the wound electronic wire, and is mounted on the pay-off shaft 4. It is then rotated and paid off by the pay-off drive motor 6.
[0033] In this embodiment, refer to Figure 2 The guiding assembly 7 includes a guide rod 71, a first guide roller 72, a second guide roller 73, and a sliding seat 74 mounted on the guide rod 71. Specifically, there are two guide rods 71, and each end of the two guide rods 71 is connected to a mounting block. The first guide roller 72 is mounted on the guide rod 71 via a connector and is located above the second guide roller 73. The second guide roller 73 is mounted on the sliding seat 74, which can slide along the guide rod 71 to drive the second guide roller 73 to move up and down. A detection device for detecting wires is provided on the support platform 1. The outer surfaces of the first guide roller 72 and the second guide roller 73 each have two or more guide rails, which are spaced apart along the axial direction of the first guide roller 72 or the second guide roller 73.
[0034] The second guide roller 73 is movably mounted on the guide rod 71 under the action of gravity. When the wire feeding shaft 4 rotates slowly, the wire will pull the second guide roller 73 closer to the first guide roller 72. Conversely, when the wire feeding shaft 4 rotates quickly, the second guide roller 73 will press the wire downward under the action of gravity to ensure the tension of the wire.
[0035] When the distance between the second guide roller 73 and the distance detection device decreases, the wire feeding drive motor 6 will increase the wire feeding speed of the wire feeding shaft 4. When the distance between the second guide roller 73 and the distance detection device increases, the wire feeding drive motor 6 will slow down the wire feeding speed of the wire feeding shaft 4. The tension of the wire will be automatically controlled by the gravity of the second guide roller 73 to prevent the wire from slack. The structure is simple, the design is ingenious, and the tension control cost is low.
[0036] By using spaced guide rails, the guiding effect on wire winding is improved, thereby preventing the wire from tangling or shifting due to slack, and thus improving the continuity and stability of wire laying.
[0037] In this embodiment, refer to Figure 4 The pressing roller 9 is rotatably mounted on the side of the control box 2 via a connecting shaft 15. The side of the control box 2 is provided with a mounting plate 16 for mounting the connecting shaft 15. The outer surface of the pressing roller 9 is in tangential contact with the outer surface of the traction roller 8. Driven by the traction drive motor 10, the traction roller 8 can pull and convey the wire, while the pressing roller 9 can press the wire against the traction roller 8, thereby ensuring the stability and continuity of the wire feeding and conveying through the traction roller 8 and the pressing roller 9.
[0038] In this embodiment, a guide plate 17 for mates with the pull-wire pressure plate 13 is provided on the side of the control box 2. A guide groove 18 matching the pull-wire pressure plate 13 is provided on the inner side of the guide plate 17, allowing the pull-wire cylinder 12 to drive the pull-wire pressure plate 13 to slide along the guide groove 18 of the guide plate 17. The guide plate 17 is located at the wire exit end of the traction roller 8 and the pressure roller 9. By providing the guide plate 17 and the guide groove 18 on it, the stability of the lifting and lowering movement of the pull-wire pressure plate 13 is improved.
[0039] By using the tension plate 13, when the wire becomes slack in the guide assembly 7 during the over-laying of the wire on the wire-laying shaft 4, the wire can be pressed down to tighten the part of the wire that passes through the guide assembly 7, further ensuring the tension control of the wire. At the same time, during the pressing process of the wire-laying cylinder 12, the second guide roller 73 of the guide assembly 7 is affected by the tension of the wire, and the wire will pull the second guide roller 73 closer to the first guide roller 72, so that the wire can stably pass through the guide assembly 7 and pass through the traction roller 8 and the pressure roller 9, thereby increasing the tension of the wire and preventing the wire from becoming too slack and causing displacement and tangling.
[0040] Specifically, at least two guide plates 17 are provided, and a sliding groove 19 for matching wire-pulling pressure plate 13 is formed between the two guide plates 17. The clamping cylinder 14 is installed on the side of the control box 2, and the telescopic end of the clamping cylinder 14 extends into the sliding groove 19, so that when the wire is pressed down through the sliding groove 19, the telescopic end of the clamping cylinder 14 moves closer to the wire-pulling pressure plate 13 so that it can be used to clamp the wire and stop the wire feeding, thereby improving the tension control of the wire after the wire feeding stops, and improving the control of the wire in the feeding mechanism.
[0041] In this embodiment, the end of the wire pressing plate 13 is arc-shaped or connected to a wire pressing roller (not shown). The arc shape or the wire pressing roller provides a protective effect when pressing down on the wire, preventing squeezing damage to the wire.
[0042] Optionally, the end of the wire pressure plate 13 is bonded with a silicone pad for pressing against the wire, thereby providing protection against the downward pressure on the wire and reducing damage caused by the downward pressure on the wire.
[0043] In this embodiment, a metal proximity sensor 20 for detecting electronic wires is connected to the side of the control box 2 via a bracket. The metal proximity sensor 20 causes the wire to be pressed down to a certain distance and then stops pressing down. At the same time, when the wire continues to be fed, the wire-pulling cylinder 12 retracts synchronously, thereby further ensuring the tension control of the wire feeding.
[0044] In this embodiment, the rotation of the wire feeding drive motor 6 enables the wire feeding shaft 4 to smoothly release the wound electronic wire, achieving automatic rotation and wire feeding of the wire feeding shaft 4. One end of the wire passes through the first guide roller 72 and the second guide roller 73, and then passes through the guide wheel and small guide wheel on the side of the control box 2, entering between the traction roller 8 and the pressure roller 9. The setting of the guiding component 7 effectively guides the transmission path of the electronic wire, ensuring the stability and tension control of the electronic wire during the production process and avoiding production failures caused by wire confusion. The combined use of the traction roller 8 and the pressure roller 9 can stably pull the electronic wire for transmission. At the same time, the pressure roller 9 presses the electronic wire against the traction roller 8, increasing the friction of transmission and preventing the electronic wire from slipping or falling off. Driven by the traction drive motor 10, the traction roller 8 can rotate continuously and stably, thereby pulling the wire and ensuring continuous transmission of the electronic wire, improving the stability of wire feeding and production efficiency.
[0045] The difference between this embodiment and the prior art is that:
[0046] Specifically, when the wire passes through the wire feeding mechanism into the subsequent equipment, the end of the wire passing through the wire feeding mechanism is fixed. The wire feeding cylinder 12 drives the wire feeding plate 13 to press down along the sliding groove 19, so that the arc-shaped end of the wire feeding plate 13 presses against the wire and pulls it down along the sliding groove 19. This ensures the tension of the wire when it enters the guide component 7 in a relaxed state when the transmission stops, and avoids loosening and tangling caused by the looseness of the wire on the guide component 7. When the wire is pressed down to the metal proximity sensor 20, the wire feeding cylinder 12 stops pressing down. At the same time, the extension end of the clamping cylinder 14 is used to hold the wire pressed down by the wire feeding plate 13 to prevent it from being displaced due to external interference, thereby improving the stability and reliability of the wire feeding production process.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
