Description

Technical Field

[0001] This utility model relates to the technical field of enameled wire take-up equipment, and in particular to an automatic reel changing device for enameled wire take-up equipment. Background Technology

[0002] Bare wire is coated multiple times to obtain enameled wire. A predetermined length of enameled wire is then wound onto a spool before packaging and transportation. To improve efficiency, winding equipment typically has multiple winding devices to simultaneously wind and wind multiple enameled wires, especially small spool winding machines which can have dozens of winding devices. Furthermore, when a winding device's spool is full, it automatically guides the enameled wire to an adjacent winding device for further winding, resulting in high winding efficiency. In existing technology, when a winding device's spool is full, the enameled wire is guided to another winding device, which cuts the wire. The wire end on the full spool is then left free, causing the wound multiple turns of enameled wire to loosen and affecting the subsequent spool packaging efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an automatic reel changing device for enameled wire take-up equipment, which can clamp two wire ends on the positioning spool and improve packaging efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution: An automatic reel changing device for an enameled wire take-up machine includes a left take-up device and a right take-up device arranged symmetrically in a central configuration. Each of the left and right take-up devices includes a protective cover, a take-up base, a take-up shaft, and a lead wire swing arm. The take-up shaft passes through the protective cover and the take-up base, and the take-up base is fixedly connected to the take-up shaft. The lead wire swing arm is located behind the protective cover. The take-up chassis is provided with at least two wire end clamping assemblies that are symmetrically arranged in the center. The multiple wire end clamping assemblies are used to clamp the two ends of the enameled wire on the spool. The bottom end of the protective cover is provided with a cutter assembly, which is located at the wire inlet clearance part of the protective cover. The lead arm of one of the left and right take-up devices is used to pull the enameled wire to the other take-up device. The upper part of the wire entry clearance portion is provided with the wire positioning component for positioning the tail end of the cut enameled wire.

[0005] Furthermore, the wire positioning assembly includes a positioning plate, which is fixed to the protective cover by screws; The upper end of the positioning plate is used for wire insertion and clamping, and the upper end of the positioning plate approaches the protective cover from the inside out.

[0006] Furthermore, the wire clamping assembly includes a base plate, a middle clamping plate, and an upper clamping plate stacked together. The base plate is fixed to the take-up base, and the mounting sections of the middle clamping plate and the upper clamping plate are fixed to the take-up base. The length of the upper clamping plate is the same as that of the clamping section of the middle clamping plate, and there is a wire inlet opening between the end of the middle clamping plate and the base plate.

[0007] Furthermore, the lead wire swing arm is rotatably mounted on the frame via a rotating shaft. A swing arm motor is fixedly mounted on the rear side of the frame. The swing arm motor is driven by the rotating shaft via a gear set. The gear set has a top limit switch and a bottom limit switch, which are electrically connected to the swing arm motor.

[0008] Furthermore, the gear set includes a meshing drive gear and a sector gear, the drive gear being fixed to the output end of the swing arm motor, and the sector gear being fixed to the rotating shaft; The two ends of the gear sector are respectively engaged with the top limit switch and the bottom limit switch.

[0009] Furthermore, a bushing is provided on the rear side of the frame, the rotating shaft is rotatably installed in the bushing, a mounting plate is fixed to the end of the bushing, and the swing arm motor is fixed to the lower part of the mounting plate. The top limit switch and the bottom limit switch are located on both sides of the top of the mounting plate.

[0010] Furthermore, a wire guide assembly is provided above the left and right take-up devices. The wire guide assembly includes a first wire guide wheel and a wire guide frame.

The wire guide frame is provided with second wire guide wheels. The second guide wheel is located between the left take-up device and the right take-up device.

[0011] The technical solution provided by this utility model can include the following beneficial effects: In this invention, by setting multiple wire end clamping components and wire positioning components in the winding device, the wire ends are positioned after the spool is fully loaded, preventing the wound enameled wire from loosening. When the fully loaded spool is removed, the positioned wire ends are pulled out and fixed to the spool, eliminating the need for manual tightening of loose wire ends and improving spool packaging efficiency. Furthermore, the tension of the enameled wire is automatically controlled during winding, remaining stable throughout the entire process. This invention eliminates the need for manual tightening of loose wire ends, ensuring uniform winding force of the enameled wire on the spool. Attached Figure Description

Detailed Implementation

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0014] The following is combined with Figures 1 to 9 This invention describes an automatic reel changing device for an enameled wire take-up device according to an embodiment of the present invention.

[0015] An automatic reel changing device for an enameled wire take-up equipment according to this embodiment includes a left take-up device 10 and a right take-up device 20 arranged symmetrically in the center. The left take-up device 10 and the right take-up device 20 each include a protective cover 1, a take-up base 2, a take-up shaft 3, and a lead wire swing arm 4. The take-up shaft 3 passes through the protective cover 1 and the take-up base 2. The take-up base 2 is fixedly connected to the take-up shaft 3. The lead wire swing arm 4 is located behind the protective cover 1. The take-up chassis 2 is provided with at least two wire end clamping assemblies 21 that are centrally symmetrical. The multiple wire end clamping assemblies 21 are used to clamp the two ends of the enameled wire on the spool. The bottom end of the protective cover 1 is provided with a cutter assembly 11, which is located at the wire entry clearance portion 12 of the protective cover 1. The lead arm 4 of one of the take-up devices, the left take-up device 10 and the right take-up device 20, is used to pull the enameled wire to the other take-up device. The upper part of the wire entry clearance part 12 is provided with a wire positioning component 13, which is used to position the tail end of the enameled wire after it has been cut.

[0016] In this invention, by setting multiple wire end clamping components 21 and wire positioning components 13 in the winding device, the wire ends are positioned after the spool is fully loaded, preventing the wound enameled wire from becoming loose. When the fully loaded spool is removed, the positioned wire ends are pulled out and fixed to the spool, eliminating the need for manual tightening of loose wire ends and improving spool packaging efficiency. On the other hand, during winding, the tension of the enameled wire is automatically controlled and remains stable throughout the winding process. However, manually tightening loose wire ends after removing a fully loaded spool makes it difficult to accurately control the winding tension. This invention eliminates the need for manual tightening of loose wire ends, ensuring uniform winding force of the enameled wire on the spool.

[0017] Specifically, when a fully loaded spool of a take-up device needs to be transferred to an unloaded take-up device for take-up (i.e., during spool changing), the lead arm 4 of the unloaded take-up device swings upward to pass over the running enameled wire. Then, when the enameled wire runs to the position corresponding to the guide wheel of the lead arm 4, the lead arm 4 swings downward, and the guide wheel guides the enameled wire to move. During the downward swing of the lead arm 4, the enameled wire is engaged in the wire positioning component 13 corresponding to the fully loaded spool. When the lead arm 4 swings downward to its lowest position, i.e., when the end of the lead arm 4 moves to the vicinity of the cutter component 11, the wire end clamping component 21 of the unloaded take-up device clamps the enameled wire and moves it toward the cutter component 11, causing the cutter component 11 to cut the enameled wire. Then, the fully loaded spool continues to rotate, pulling the wire end out of the wire positioning component 13 and capturing it with the wire end clamping component 21, thus achieving wire end clamping and positioning. Understandably, providing multiple wire end clamping assemblies 21 allows for more reliable positioning of the enameled wire end. Preferably, a take-up device has two or three wire end clamping assemblies 21.

[0018] In one embodiment of the present invention, the wire positioning assembly 13 includes a positioning plate 131, which is fixed to the protective cover 1 by screws; The upper end of the positioning plate 131 is used for wire insertion and clamping, and the upper end of the positioning plate 131 approaches the protective cover 1 from the inside out.

[0019] The wire positioning assembly 13 is used to position the enameled wire and provide tension between the wire end clamping assembly 21 and the wire positioning assembly 13 when the spool is fully loaded. This not only provides sufficient winding tension but also facilitates the wire end clamping assembly 21 in holding the enameled wire. The upper end of the positioning clamping plate 131 is tilted so that it can clamp the cut enameled wire when the spool is fully loaded without interfering with the wire entry when unloaded. Preferably, the outer side of the upper end of the positioning clamping plate is in contact with the protective cover 1.

[0020] In one embodiment of this utility model, the wire clamping assembly 21 includes a base plate 211, a middle clamping plate 212, and an upper clamping plate 213 stacked together. The base plate 211 is fixed to the take-up base plate 2. The mounting sections of the middle clamping plate 212 and the upper clamping plate 213 are fixed to the take-up base plate 2. The length of the upper clamping plate 213 is the same as the clamping section of the middle clamping plate 212. The end of the middle clamping plate 212 has a wire entry opening between it and the base plate 211.

[0021] When the wire end clamping assembly 21 clamps the enameled wire, the wire enters from the wire inlet between the middle clamping plate 212 and the bottom plate 211. Based on the clamping effect of the middle clamping plate 212 and the upper clamping plate 213, the enameled wire is clamped between the middle clamping plate 212 and the bottom plate 211. The upper clamping plate 213 is used to enhance the stability of the wire end clamping. And when the upper clamping plate 213 is wavy and the middle clamping plate 212 has a small thickness, the wire end clamping assembly 21 can simultaneously and securely clamp both ends of the enameled wire.

[0022] In one embodiment of this utility model, the lead wire swing arm 4 is rotatably mounted on the frame 40 via a rotating shaft 41. A swing arm motor 42 is fixedly mounted on the rear side of the frame 40. The swing arm motor 42 is driven by the rotating shaft 41 via a gear set. The gear set has a top limit switch 43 and a bottom limit switch 44. The top limit switch 43 and the bottom limit switch 44 are electrically connected to the swing arm motor 42.

[0023] In existing technologies, the swing arm is directly driven by a motor, with the motor controlled by a PLC to control the swing of the arm. Compared to direct motor-driven swing arms, this solution uses limit switches to limit the swing position of the lead-wire swing arm 4, resulting in higher reliability. Furthermore, the use of gear transmission allows for precise control of the swing speed of the lead-wire swing arm 4.

[0024] Furthermore, the gear set includes a meshing drive gear 45 and a sector gear 46, the drive gear 45 being fixed to the output end of the swing arm motor 42, and the sector gear 46 being fixed to the rotating shaft 41; The two ends of the gear sector 46 are respectively engaged with the top limit switch 43 and the bottom limit switch 44.

[0025] The two ends of the sector teeth have protrusions, which can be used in conjunction with limit switches to simplify the device structure.

[0026] Specifically, a bushing 47 is provided on the rear side of the frame 40, the rotating shaft 41 is rotatably installed in the bushing 47, a mounting plate 48 is fixed at the end of the bushing 47, and the swing arm motor 42 is fixed to the lower part of the mounting plate 48; the top limit switch 43 and the bottom limit switch 44 are located on both sides of the top of the mounting plate 48.

[0027] In this scheme, the swing arm motor 42 is supported by bushing 47, which simplifies the installation structure of the motor. The structure is simple and compact, and the installation of the lead-wire swing arm 4, the swing arm motor 42, the gear set and the limit switch is convenient and easy to maintain.

[0028] In one embodiment of the present invention, a wire assembly 30 is provided above the left take-up device 10 and the right take-up device 20. The wire assembly 30 includes a first wire wheel 301 and a wire frame 302. A plurality of first wire wheels 301 are positioned on the frame 40 and above the wire frame 302. The wire wheels are movably disposed on the frame 40. The wire frame 302 is provided with a second wire wheel 303. The second guide wheel 303 is located between the left take-up device 10 and the right take-up device 20.

[0029] The conductor assembly 30 is used to guide an enameled wire to the left take-up device 10 or the right take-up device 20. When the conductor frame 302 moves back and forth, the second conductor wheel 303 can drive the enameled wire to move back and forth, so that the enameled wire can be wound more evenly on the corresponding spool.
