Description

Technical Field

[0001] This utility model relates to the field of wire feeding, and in particular to a wire feeding and storage device. Background Technology

[0002] One type of conduit has a pre-embedded thread inside during production. During installation, after the conduit is laid out, the exposed thread connects to the electrical wire, and the wire is then pulled through the other end of the thread to smoothly thread the wire into the conduit. This type of conduit is produced using an extrusion process, where the thread is passed through the extrusion die and simultaneously stretched. However, a problem exists during production: the thread is produced in coils, and after one coil is used up, the next coil needs to be added promptly. This window is very short, requiring workers to constantly monitor and quickly replace and reconnect the thread as it nears depletion. This results in significant workload for workers during thread replacement, and failure to reconnect in time can lead to a restart of the machine. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the problem is: a wire feeding and storage device, comprising: A wire storage rack includes a fixed wheel and a movable wheel. The movable wheel can move on the wire feeding rack in a direction toward the fixed wheel. The fixed wheel is provided with a plurality of fixed wheel grooves, and the movable wheel is provided with a plurality of movable wheel grooves. The movable wheel is normally away from the fixed wheel. The fixed wheel grooves and movable wheel grooves are used to allow the wire to pass around.

The detection sensor is electrically connected to the drive motor and is also electrically connected to an alarm device.

[0005] As a further improvement to the above technical solution, the movable wheel is located below the fixed wheel, and the movable wheel moves away from the fixed wheel by gravity.

[0006] As a further improvement to the above technical solution, the wire storage rack is provided with a track, the fixed wheel is located at the end of the wire storage rack, and the movable wheel is installed on the track.

[0007] As a further improvement to the above technical solution, a first rotating shaft is provided on the top of the wire storage rack, and the fixed wheel is pivotally connected to the first rotating shaft. The movable wheel is pivotally connected to a sliding seat, which is slidably arranged on the track.

[0008] As a further improvement to the above technical solution, it also includes a lifting rail, on which the lifting component is movably mounted.

[0009] As a further improvement to the above technical solution, a guide wheel assembly is also provided between the lifting component and the wire feeding wheel assembly. The guide wheel assembly consists of two guide rollers that abut against each other. Each guide roller has a V-groove on its surface, and the two V-grooves fit together.

[0010] As a further improvement to the above technical solution, two guide rollers are arranged horizontally, and a support seat is provided below the two guide rollers; the support seat is arranged on the top of the lifting rail, and an extension body is provided on the lifting component, the extension body is sleeved on the lifting rail so that the lifting component is located at the front end of the guide roller assembly.

[0011] As a further improvement to the above technical solution, the lifting component includes a main body, the wire passage is located at the lower part of the main body and extends to both sides of the main body, and the front and rear sides of the upper part of the main body are provided with fixed plates extending away from the wire feeding wheel group. A first wire guide wheel is pivotally connected between the fixed plates, and the bottom of the first wire guide wheel is lower than the top of the wire passage.

[0012] As a further improvement to the above technical solution, a second guide wheel is provided between the wire feeding wheel assembly and the wire storage frame, and the height of the second guide wheel is located between the wire feeding wheel and the wire pressing wheel.

[0013] As a further improvement to the above technical solution, the wire feeding wheel assembly includes an inclined connecting bracket, the top of the connecting bracket is pivotally connected to the pressure wheel, the pressure wheel is located directly above the wire feeding wheel, the bottom of the connecting bracket is pivotally connected to an auxiliary pressure wheel, the auxiliary pressure wheel is located between the second guide wheel and the wire feeding wheel, the wire feeding wheel assembly is provided with a reference frame located above the connecting bracket, and the top of the reference frame and the connecting bracket are provided with vertically arranged compression springs.

[0014] The beneficial effects of this invention are as follows: When connecting the wire to the extruder, the wire is first passed through the wire feed port, then through the wire feeding wheel assembly, so that the wire is located between the wire feeding wheel and the pressure wheel and is clamped. The wire is then wound back and forth between the fixed wheel groove and the movable wheel groove, at which point the distance between the movable wheel and the fixed wheel is at its maximum. Afterwards, it is connected to the extruder. Because the wire has wound multiple times between the fixed wheel and the movable wheel, a large amount of intermediate wire is formed. Before the wire is completely drawn from the rope reel, the wire between the wire feeding wheel assembly and the rope reel is in a taut state. At this time, the wire will lift the lifting component to form a suspended state. During production, controlling the speed of the drive motor can control the speed of wire feeding. When the wire is completely drawn from the rope reel, because the end of the wire is no longer restricted... At this point, the thread at the front end of the lifting component is slack and cannot support it, causing the lifting component to fall and be detected by the sensor. The sensor sends a signal to the drive motor and alarm device, which sounds an alarm indicating that the thread is used up. Simultaneously, the drive motor stops, causing the feeding wheel and pressure wheel to completely clamp the thread, preventing the end of the thread from moving. Since the storage rack stores a large amount of intermediate thread through fixed and movable wheels, the extruder continuously extracts the intermediate thread stored between these wheels. During extraction, as the thread is continuously removed, the movable wheel moves towards the fixed wheel. The number of grooves in the movable and fixed wheels, as well as the distance between them, determines the length of the intermediate thread. The presence of this intermediate thread provides workers with ample window time, allowing them to more easily and efficiently place the next roll of thread onto the reel and complete the splicing process. After the wiring work is completed, the staff actively controls the drive motor to continue feeding the wire. The drive motor delivers the wire at a speed that is faster than usual, thereby replenishing the intermediate amount of wire on the wire storage rack and allowing the movable wheel to return to a position away from the fixed wheel to prepare for the next wiring operation.

[0021] Reference Figures 1 to 2 A wire feeding and storage device, comprising: The wire storage rack 10 includes a fixed wheel body 11 and a movable wheel body 12. The movable wheel body 12 can move on the wire feeding rack in a direction toward the fixed wheel body 11. The fixed wheel body 11 is provided with a plurality of fixed wheel grooves 111, and the movable wheel body 12 is provided with a plurality of movable wheel grooves 121. The movable wheel body 12 is normally away from the fixed wheel body 11. The fixed wheel grooves 111 and the movable wheel grooves 121 are used to allow the wire to be wound around. The wire feeding wheel assembly 20 includes a wire feeding wheel 21 and a wire pressing wheel 22 that cooperates with the wire feeding wheel 21. The wire feeding wheel assembly 20 is located at the front end of the wire storage rack 10. A drive motor 23 is connected to the wire feeding wheel 21. The lifting component 30 is provided with a wire passage 31, through which the wire passes through the lifting component 30 and can lift the lifting component 30. A detection sensor 40 is located at the bottom of the lifting path of the lifting component 30. The detection sensor 40 is electrically connected to the drive motor 23 and is electrically connected to an alarm device.

[0022] The wire is arranged on the rope reel 1. When connecting the wire to the extruder, the wire is first passed through the wire inlet 31, and then through the wire feeding wheel assembly 20, so that the wire is located between the wire feeding wheel 21 and the pressure wheel 22 and is clamped. Then, the wire is wound back and forth between the fixed wheel groove 111 and the movable wheel groove 121. At this time, the distance between the movable wheel 12 and the fixed wheel 11 is at its maximum. Then it is connected to the extruder. Because the wire has wound around the fixed wheel 11 and the movable wheel 12 multiple times, a large amount of intermediate wire is formed. When the wire is not completely pulled from the rope reel 1, the wire between the wire feeding wheel assembly 20 and the rope reel 1 is in a taut state. At this time, the wire will lift the lifting component 30 to form a suspended state. During production, the speed of the drive motor 23 can be controlled to control the speed of wire feeding. When the wire is completely pulled from the rope reel 1, since the end of the wire is no longer restricted, the wire is located at the end of the rope reel 1. The wire at the front end of the lifting component 30 is in a slack state and cannot support the lifting component 30. The lifting component 30 will fall and be detected by the detection sensor 40. The detection sensor 40 feeds back a signal to the drive motor 23 and the alarm device. The alarm device sounds an alarm indicating that the wire is used up. At the same time, the drive motor 23 stops, so that the wire feeding wheel 21 and the wire pressing wheel 22 completely clamp the wire. The end of the wire cannot move. At this time, since a large amount of intermediate wire is stored on the wire storage rack 10 through the fixed wheel body 11 and the movable wheel body 12, the extruder extracts the intermediate wire stored between the fixed wheel body 11 and the movable wheel body 12 during the continuous wire extraction process. During the extraction process, as the wire is continuously extracted, it will drive the movable wheel body 12 to move towards the fixed wheel body 11. The number of movable wheel grooves 121 and fixed wheel grooves 111, as well as the distance between the fixed wheel body 11 and the movable wheel body 12, determine the length of the intermediate wire. The presence of intermediate thread provides workers with ample window time, allowing them to more easily and calmly place the next roll of thread onto the rope reel 1 and complete the splicing work. After completing the splicing work, the worker actively controls the drive motor 23 to continue feeding thread, and the drive motor 23 feeds thread at a faster speed than usual, thereby replenishing the intermediate thread on the thread storage rack 10, allowing the movable wheel 12 to return to a position away from the fixed wheel 11 to prepare for the next splicing operation.

[0023] Preferably, a position sensor 70 is provided at the end of the moving path of the movable wheel 12. The position sensor 70 is electrically connected to the drive motor 23. After the wiring is completed and the wire feeding wheel group 20 resumes operation, the drive motor 23 first feeds the wire quickly to quickly replenish the intermediate amount of wire. Then, when the movable wheel 12 returns to the end of the moving path, the position sensor 70 is activated, so that the drive motor 23 resumes normal speed operation.

[0024] Further optimization involves various methods to ensure the movable wheel 12 moves away from the fixed wheel 11 under normal conditions. A common method is to place a spring between the fixed wheel 11 and the movable wheel 12, causing the spring to drive the movable wheel 12 away from the fixed wheel 11. To reduce the number of structures and lower costs, it is preferable that the movable wheel 12 is located below the fixed wheel 11, and that the movable wheel 12 moves away from the fixed wheel 11 by gravity. Furthermore, to ensure the accuracy of the movable wheel 12's movement direction, it is preferable that the wire storage rack 10 is equipped with a track 14, with the fixed wheel 11 located at the end of the wire storage rack 10 and the movable wheel 12 mounted on the track 14.

[0025] In this design, the fixed wheel 11 and the movable wheel 12 cannot rotate, yet they can still store and move the thread. However, this creates sliding friction between the fixed wheel groove 111 and the movable wheel groove 121, resulting in resistance. Therefore, it is preferable that the top of the thread storage rack 10 is provided with a first rotating shaft, and the fixed wheel 11 is pivotally connected to the first rotating shaft; the movable wheel 12 is pivotally connected to a sliding seat 13, which is slidably arranged on the track 14. This allows both the movable wheel 12 and the fixed wheel 11 to rotate freely, reducing resistance as the thread moves between them.

[0026] To further optimize the lifting range and accuracy of the lifting component 30, it is preferable to also include a lifting rail 50, on which the lifting component 30 is movably mounted.

[0027] To further optimize the process and ensure the yarn enters the feed roller assembly 20 more smoothly after passing through the lifting member 30, a guide roller assembly 60 is preferably provided between the lifting member 30 and the feed roller assembly 20. The guide roller assembly 60 consists of two abutting guide rollers, each with a V-groove on its surface, and the two V-grooves interlock. The guide roller assembly 60 guides the yarn's direction, making its entry into the feed roller assembly 20 more stable. Furthermore, to simplify the structure, the two guide rollers are preferably arranged horizontally, with a support base below them. The support base is located on the top of the lifting rail 50. An extension body 32 is provided on the lifting member 30, and the extension body 32 is fitted onto the lifting rail 50 so that the lifting member 30 is positioned at the front end of the guide roller assembly 60.

[0028] In this design, the lifting component 30 has various structures, such as being shaped like a pendant. Considering ease of processing and smooth wire movement, the lifting component 30 preferably includes a main board. The wire passage 31 is located at the lower part of the main board and extends to both sides of the main board. Fixed plates extending away from the wire feeding wheel assembly 20 are provided on both the front and rear sides of the upper part of the main board. A first wire guide wheel 33 is pivotally connected between the fixed plates. The bottom of the first wire guide wheel 33 is lower than the top of the wire passage 31, so that when the lifting component 30 is lifted, rolling friction is generated through the first wire guide wheel 33, reducing the resistance to wire movement.

[0029] Further optimization is preferred, with a second guide wheel 15 provided between the wire feeding wheel group 20 and the wire storage rack 10. The height of the second guide wheel 15 is located between the wire feeding wheel 21 and the pressure wheel 22, so that the wire can be output from the wire feeding wheel group 20 horizontally or at a small angle.

[0030] The pressure roller 22 can be directly pressed against the surface of the feed roller 21 by a mechanical structure, or it can be driven by an elastic element to press the pressure roller 22 against the surface of the feed roller 21. In this embodiment, the feed roller assembly 20 preferably includes an inclined connecting bracket 25. The pressure roller 22 is pivotally connected to the top of the connecting bracket 25 and is located directly above the feed roller 21. An auxiliary pressure roller 26 is pivotally connected to the bottom of the connecting bracket 25 and is located between the second guide roller 15 and the feed roller 21. A reference frame 24 is provided on the feed roller assembly 20 above the connecting bracket 25. Vertically arranged compression springs are provided on the top of the reference frame 24 and the connecting bracket 25. The compression springs ensure that the pressure roller 22 presses the yarn while preventing the yarn from being completely crushed. The auxiliary pressure roller 26 can also help control the stability of the yarn transport process. Preferably, the reference frame 24 is provided with an adjustment device for adjusting the height of the compression springs.

[0031] In this design, the fixed wheel 11 and the movable wheel 12 can be a single, complete wheel or a combination of multiple wheels; their specific configurations can be determined based on actual requirements. For example, the movable wheel 12 can be... Figure 2 As shown, several movable wheel grooves 121 are arranged in parallel around the outer periphery of a complete cylindrical structure; the movable wheel body 12 can also be a combination of multiple movable pulleys, each of which can move independently.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
