Description

Technical Field

[0001] This invention relates to an automatic wire feeding device, and more specifically to an automatic wire feeding device with tray locking. Background Technology

[0002] A wire-feeding machine is an auxiliary device for wires and cables, used in conjunction with a stranding machine, to feed wires. Traditional wire-feeding machines primarily use a motor to drive a reel to feed wires. These machines lack a device to detect the tension of the wire bundle, making it impossible to effectively feedback tension signals. This often leads to wire bundle accumulation due to excessive feeding or jamming due to insufficient feeding, affecting subsequent wire shearing. Because the reels vary in size and the coil shape gradually changes as the wire is fed, existing cable guiding devices, being fixed in place, cannot guarantee accurate feeding. Cable pulling is common, resulting in low efficiency and damage to the machine, increasing maintenance costs. Furthermore, the lack of locking mechanisms for the reel and support for the feeding shaft during operation allows the reel to loosen on the shaft, causing feeding deviation. Excessive bearing weight or prolonged use can lead to wear and tear, affecting the feeding position of the reel.

[0003] In view of this, the present invention designs an automatic wire feeding device with tray locking. Summary of the Invention

[0004] The main objective of this disclosure is to provide an automatic wire feeding device with tray locking, so as to effectively solve the problems raised by the inventors in the above-mentioned background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An automatic wire feeding device with reel locking includes a wire feeding machine main unit, a wire feeding shaft, and a wire reel body. The wire feeding shaft is rotatably mounted inside the wire feeding machine main unit, and the front end of the wire feeding shaft extends outside the wire feeding machine main unit. The wire reel body is detachably mounted on the outer end of the wire feeding shaft, i.e., the wire reel body is located on the front of the wire feeding machine main unit. The bottom of the wire feeding machine main unit has an installation port, and two symmetrically arranged support platforms are movably mounted in the installation port. Support frames are movably mounted on the upper ends of the two support platforms, and rolling friction wheels are rotatably mounted on the two support frames. The rolling friction wheels are located to the side and below the front end of the wire feeding shaft, and the rolling friction wheels are located outside the installation port. The two support platforms move in opposite directions. Two main unit mounting brackets are fixedly mounted on the left side of the front of the wire feeding machine main unit, and a linear guide rail is fixedly mounted between the two main unit mounting brackets. A straightening mechanism is movably mounted on the linear guide rail, and a guide wheel assembly is mounted on the straightening mechanism.

[0007] Preferably, a support column is fixedly installed in the mounting port, and both support platforms are slidably installed on the support column. An X-axis bidirectional threaded rod is rotatably installed in the mounting port, and the two support platforms are respectively threaded onto the X-axis bidirectional threaded rod at opposite thread ends. A first stepper motor is fixedly installed on the wire feeding machine host, and the output end of the first stepper motor is fixedly connected to the X-axis bidirectional threaded rod.

[0008] Preferably, the support platform has a mechanical cavity inside, and a smooth plate is slidably installed in the mechanical cavity. The lower end of the support frame is slidably installed through the upper end of the support platform, and the bottom end of the support frame is fixedly connected to the top of the smooth plate. A toggle shaft is rotatably installed in the mechanical cavity, and an elliptical block is fixedly installed on the toggle shaft. The short axis side of the elliptical block contacts the bottom of the smooth plate.

[0009] Preferably, a drive gear is fixedly mounted on the actuating shaft, a notch is provided at the bottom of the smooth plate, and the upper end of the drive gear extends into the notch. The thickness of the elliptical block is greater than the width of the notch. A driven rack is slidably mounted on the inner bottom wall of the mechanical cavity, and the driven rack meshes with the drive gear for transmission. A through hole is provided on the side of each of the two support platforms that are close to each other, and the through hole communicates with the mechanical cavity. One end of the driven rack moves through the through hole and extends to the outside of the support platform, and a return spring is fixedly connected to the other end of the driven rack. The other end of the return spring is fixedly connected to the inner wall of the mechanical cavity.

[0010] Preferably, the correction mechanism includes a groove, a correction slide, a Y-axis one-way threaded rod, a follower gear, a reduction shaft, and a reduction gear. The top of the linear guide rail has a groove, and the Y-axis one-way threaded rod is rotatably installed in the groove. The correction slide is threaded onto the Y-axis one-way threaded rod and slidably installed in the groove. The guide wheel assembly is installed on the correction slide. The rear end of the Y-axis one-way threaded rod extends into the main body of the wire feeding machine. The rear end of the Y-axis one-way threaded rod and the portion of the wire feeding shaft located inside the main body of the wire feeding machine are both fixedly installed with follower gears. Two reduction shafts of equal height are rotatably installed inside the main body of the wire feeding machine, and reduction gears are fixedly installed on both reduction shafts. The two reduction gears mesh with each other for transmission. The follower gear on the Y-axis one-way threaded rod meshes with the reduction gear on the left side for transmission, and the follower gear on the wire feeding shaft meshes with the reduction gear on the right side for transmission.

[0011] Preferably, the diameter of the follower gear on the Y-axis one-way threaded rod is larger than the diameter of the follower gear on the wire feeding shaft, and the diameter of the reduction gear is smaller than the diameter of the follower gear on the Y-axis one-way threaded rod.

[0012] Preferably, the front side of the wire feeding shaft has three automatic locking slots arranged in a circular array. An opening and closing shaft is rotatably installed inside the automatic locking slots, and a special-shaped clamping head is fixedly installed on the opening and closing shaft. All three special-shaped clamping heads are clamped on the front side of the wire reel body.

[0013] Preferably, a parallel slide rail is slidably installed inside the automatic locking port, and a rack in the same direction is fixedly connected to the front end of the parallel slide rail. A mechanical gear is fixedly installed on the opening and closing shaft, and the mechanical gear meshes with the rack in the same direction for transmission. A groove is provided on the side of the wire feeding shaft, and an L-shaped force key is slidably connected in the groove. The L-shaped force key is fixedly connected to the rear end of the parallel slide rail, and the bent section of the L-shaped force key is located outside the wire feeding shaft. The rear side of the wire spool body is pressed against the bent end of the L-shaped force key.

[0014] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0015] (i) In this application, when loading the reel, the main body of the reel is placed on the pay-off shaft. The rear side of the main body of the reel will press the L-shaped force key, causing the parallel slide rail to slide backward in the automatic locking slot. The rack in the same direction will move accordingly. Under the meshing transmission action of the rack and the mechanical gear, the opening and closing shaft will rotate, causing the special-shaped clamping head to swing and clamp onto the front of the main body of the reel. The main body of the reel will not easily loosen on the pay-off shaft, so that the main body of the reel can be automatically locked on the pay-off shaft. The automatic locking function of the reel is achieved through the reel loading action.

[0016] (II) In this application, before the wire feeding operation, the first stepper motor works, causing it to drive the X-axis bidirectional threaded rod to rotate. The two support platforms will slide towards each other along the support column. When the support platforms are about to move below the wire feeding shaft, the driven racks on the two support platforms will contact each other. As the support platforms continue to move, the driven racks will move into the mechanical cavity until the two support platforms touch each other. At this time, the support platforms block in front of the wire reel body, further preventing the wire reel body from detaching from the wire feeding shaft. When the driven rack slides into the mechanical cavity, the drive gear drives the actuating shaft to rotate, causing the elliptical block to rotate and push the smooth plate upward. The support frame will then move upward with the rolling friction wheels, so that the two rolling friction wheels contact the wire feeding shaft to provide movable support for the wire feeding shaft, thereby reducing the load on the wire feeding shaft, preventing it from deforming and causing the wire reel body to deviate, and ensuring the accuracy of wire feeding.

[0017] (III) In this application, during cable feeding, the cable on the main body of the reel is passed through the guide pulley so that the cable can be pulled and guided to avoid confusion. The servo motor of the external device works, which drives the cable feeding shaft to rotate, thereby driving the main body of the reel to feed the cable. The follower gear on the cable feeding shaft drives the reduction gear to rotate, and finally drives another follower gear to rotate, so that the Y-axis one-way threaded rod rotates slowly. Then the straightening slide moves slowly along the groove, and the guide wheel assembly moves slowly along with it. The cable feeding position on the main body of the reel will gradually shift. This invention will automatically adjust the position of the guide wheel assembly according to the position of the cable on the main body of the reel, so that the cable can be straightened in real time, avoid being pulled, and the cable feeding effect is better.

[0039] Specifically, a support column 101 is fixedly installed at the mounting port, and two support platforms 4 are slidably installed on the support column 101. An X-axis bidirectional threaded rod 102 is rotatably installed inside the mounting port, and the two support platforms 4 are respectively threaded onto the opposite thread ends of the X-axis bidirectional threaded rod 102. A first stepper motor 103 is fixedly installed on the main body 1 of the wire feeding machine, and the output end of the first stepper motor 103 is fixedly connected to the X-axis bidirectional threaded rod 102.

The other end of the return spring 408 is fixedly connected to the inner wall of the mechanical cavity.

[0040] Specifically, the straightening mechanism includes a groove, a straightening slide 601, a Y-axis one-way threaded rod 602, a follower gear 603, a reduction shaft 104, and a reduction gear 105. A groove is provided on the top of the linear guide rail 6, and the Y-axis one-way threaded rod 602 is rotatably mounted within the groove. The straightening slide 601 is threaded onto the Y-axis one-way threaded rod 602 and slidably mounted within the groove. The guide wheel assembly 7 is mounted on the straightening slide 601. The rear end of the Y-axis one-way threaded rod 602 extends into the main body 1 of the wire feeding machine, and the Y-axis one-way threaded rod... The rear end of the threaded rod 602 and the part of the wire feeding shaft 2 located inside the wire feeding machine main unit 1 are both fixedly equipped with follower gears 603. Two reduction shafts 104 with the same height are rotatably installed inside the wire feeding machine main unit 1, and reduction gears 105 are fixedly installed on both reduction shafts 104. The two reduction gears 105 mesh with each other for transmission. The follower gear 603 on the Y-axis one-way threaded rod 602 meshes with the reduction gear 105 on the left side for transmission, and the follower gear 603 on the wire feeding shaft 2 meshes with the reduction gear 105 on the right side for transmission.

[0041] Specifically, the diameter of the follower gear 603 on the Y-axis one-way threaded rod 602 is larger than the diameter of the follower gear 603 on the wire feeding shaft 2, and the diameter of the reduction gear 105 is smaller than the diameter of the follower gear 603 on the Y-axis one-way threaded rod 602.

[0042] Specifically, the front side of the pay-off shaft 2 has three automatic locking slots 201 arranged in a circular array. An opening and closing shaft 202 is rotatably installed inside the automatic locking slots 201, and a special-shaped clamping head 203 is fixedly installed on the opening and closing shaft 202. All three special-shaped clamping heads 203 clamp the front side of the spool body 3. A parallel slide rail 204 is slidably installed inside the automatic locking slots 201, and a rack 206 in the same direction is fixedly connected to the front end of the parallel slide rail 204. A mechanical gear 205 is fixedly installed on the opening and closing shaft 202, and the mechanical gear 205 meshes with the rack 206 in the same direction for transmission. A sliding groove is opened on the side of the pay-off shaft 2, and an L-shaped force key 207 is slidably connected in the sliding groove. The L-shaped force key 207 is fixedly connected to the rear end of the parallel slide rail 204, and the curved section of the L-shaped force key 207 is located outside the pay-off shaft 2. The rear side of the spool body 3 is pressed against the curved end of the L-shaped force key 207.

[0043] Specifically, the guide wheel assembly 7 consists of a connecting rod, guide pulleys, and other structures. Two guide pulleys are rotatably mounted on the connecting rod, which is distributed vertically. The connecting rod is fixedly mounted on the top of the straightening slide 601. During the cable feeding operation, the cable on the cable reel body 3 passes between the two guide pulleys, and the guide pulleys pull the cable to ensure that it can be fed in an orderly manner.

[0044] The specific implementation of this embodiment is as follows: When the main body 3 of the wire reel is not assembled, the special-shaped clamping head 203 is in a state of parallelity with the wire feeding shaft 2, so that it will not swing and unfold. Then the diameter of the wire feeding shaft 2 will not change, so that the main body 3 of the wire reel can be fitted on the wire feeding shaft 2 when it is loaded into the reel later. At this time, the distance between the two rolling friction wheels 402 is larger than the diameter of the main body 3 of the wire reel, avoiding the obstruction of the support platform 4, which is conducive to the subsequent loading into the reel. The rolling friction wheels 402 are slightly lower than the wire feeding shaft 2.

[0045] During the loading process, the main body 3 of the spool is placed on the pay-off shaft 2. The rear side of the main body 3 will press the L-shaped force key 207, causing the parallel slide rail 204 to slide backward within the automatic locking port 201. The rack 206 moves accordingly, and under the meshing transmission action of the rack and the mechanical gear 205, the opening and closing shaft 202 rotates, causing the special-shaped clamping head 203 to swing and clamp onto the front of the main body 3 of the spool. The main body 3 of the spool will not easily loosen on the pay-off shaft 2, so that the main body 3 of the spool can be automatically locked on the pay-off shaft 2. The automatic locking function of the spool is achieved through the loading action.

[0046] During cable feeding, the cable on the main body 3 is passed through the guide pulley to allow the cable to be pulled and guided, preventing tangling. The peripheral servo motor works, which drives the feeding shaft 2 to rotate, thereby driving the main body 3 to feed the cable. The follower gear 603 on the feeding shaft 2 drives the reduction gear 105 to rotate, which in turn drives another follower gear 603 to rotate, causing the Y-axis one-way threaded rod 602 to rotate slowly. The straightening slide 601 then moves slowly along the groove, and the guide wheel assembly 7 moves slowly along with it. The feeding position of the cable on the main body 3 will gradually shift. This invention will automatically adjust the position of the guide wheel assembly 7 according to the position of the cable on the main body 3, so that the cable can be straightened in real time, avoiding being pulled, and the feeding effect is better.

[0047] Before the wire feeding operation, the first stepper motor 103 starts working, driving the X-axis bidirectional threaded rod 102 to rotate. The two support platforms 4 will slide towards each other along the support column 101. When the support platforms 4 are about to move below the wire feeding shaft 2, the driven racks 407 on the two support platforms 4 will contact each other. As the support platforms 4 continue to move, the driven racks 407 will move into the mechanical cavity until the two support platforms 4 touch. At this time, the support platforms 4 block in front of the wire reel body 3, further preventing the wire reel body 3 from detaching from the wire feeding operation. The rotating shaft 2, when the driven rack 407 slides into the mechanical cavity, the driving gear 406 drives the actuating shaft 404 to rotate, causing the elliptical block 405 to rotate and push the smooth plate 403 upward. The support frame 401 will then move the rolling friction wheel 402 upward, so that the two rolling friction wheels 402 contact the front end 2 of the wire feeding shaft to provide movable support for the wire feeding shaft 2, thereby reducing the burden on the wire feeding shaft 2, preventing it from deforming and causing the main body of the wire reel 3 to deviate, and ensuring the accuracy of wire feeding.
