Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire feeding equipment technology, and in particular to an automatic wire feeding device for spools. Background Technology
[0002] Coil is the core carrier for storing and transporting copper wire and other wires. Currently, most existing coils are not equipped with dedicated automatic wire feeding devices. In actual operation, the copper wire is directly pulled out from the edge of the coil by external force.
[0003] Due to the lack of effective guiding and limiting structures, the copper wire is prone to friction and jamming with the edge of the spool during the pulling process. Especially when the wire pulling direction changes or the spool rotation is not smooth, the copper wire is very likely to get stuck in the gaps or corners of the spool edge. This will not only cause the copper wire to break or become thinner, affecting the integrity and dimensional accuracy of the wire, but also damage the enamel coating on the surface of the copper wire, destroying the insulation performance and appearance quality of the wire, and thus affecting the assembly accuracy and reliability of subsequent products. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes an automatic bobbin feeding device.
[0005] This utility model proposes an automatic spool unloading device, including a spool and wire wound around the outside of the spool. A rotating seat is rotatably connected to the upper part of the spool, and a bearing is fixed inside the rotating seat. A first arm plate is connected to one side of the rotating seat, and a wire guide tube is installed at the end of the first arm plate. The bottom end of the screw extends to the bottom of the spool and is fitted with a limiting plate that abuts against the bottom end of the spool and is locked by fastening bolts. The free end of the wire passes through a lead hole opened at the outer end of the wire guide tube.
[0006] Furthermore, the bottom end of the coil is provided with a mounting hole, and the limiting plate and fastening bolts are both hidden inside the mounting hole.
[0007] Furthermore, the interior of the rotating seat has a pre-drilled hole, and a number of fastening protrusions are integrally connected around the inner side of the pre-drilled hole. The bearing is located inside the pre-drilled hole and is fixed by squeezing the fastening protrusions. The rotating seat is connected to the outer ring of the bearing.
[0008] Furthermore, the first arm plate has an elongated adjustment hole inside, and the end of the cable management tube opposite to the lead hole has an adjustment opening, and a through hole connected to the adjustment opening is also provided. The first arm plate is inserted into the adjustment opening, and an adjustable fastening structure is formed through the through hole and the adjustment hole, so that the position of the cable management tube can be adapted to different sizes of cable reels.
[0009] Furthermore, an upper limiting bolt and a lower limiting bolt are respectively connected to the outside of the screw. The upper limiting bolt and the lower limiting bolt are located at the upper and lower parts of the bearing, respectively, and both abut against the inner ring of the bearing.
[0010] Furthermore, an upper washer is fitted around the outside of the screw, and the upper washer is located between the upper limiting bolt and the bearing.
[0011] Furthermore, a lower washer is fitted around the outside of the screw, and the lower washer is located between the coil and the rotating seat.
[0012] The beneficial effects of this utility model are as follows: the guiding action of the cable management tube and the cooperation between the rotating seat and the bearing achieve low-resistance rotation. Combined with the adjustable structure of the cable management tube to adapt to different specifications of cable reels, it can not only avoid the problems of cable tangling, jamming and getting stuck on the edge of the reel when the cable is unloaded, thus protecting the integrity and surface quality of the cable, but also improve the smoothness of unloading and work efficiency. Moreover, the overall structure is compact, the installation is firm, and the adaptability is strong. Attached Figure Description

[0015] Reference Figure 1-6The present invention proposes an automatic wire feeding device for spools, including a spool 1, which serves as the storage and support base for wire 101. The wire 101 is regularly wound around the outside of the spool 1 to provide raw material supply for automatic wire feeding operations. A rotating seat 2 is rotatably connected to the upper part of the spool 1. A reserved hole 21 is provided through the interior of the rotating seat 2. Several fastening protrusions 22 are integrally formed around the inner side of the reserved hole 21. A bearing 3 is adapted to be installed inside the reserved hole 21. By squeezing the fastening protrusions 22, the bearing 3 can be firmly fixed in the reserved hole 21. The rotating seat 2 is directly connected to the outer ring of the bearing 3 to ensure that the rotating seat 2 can rotate synchronously and stably with the outer ring of the bearing. A first arm plate 23 is integrally connected to one side of the rotating base 2. An elongated adjustment hole 25 is provided inside the first arm plate 23, offering travel space for adjusting the position of the cable management tube 5. An adjustment opening 51 is provided at the end of the cable management tube 5 away from the lead hole 53. Through holes 52 are correspondingly provided at the top and bottom of the adjustment opening 51. The first arm plate 23 is inserted into the adjustment opening 51. An adjusting bolt 12 passes through the through hole 52 and the adjustment hole 25, forming an adjustable fastening structure. Loosening the adjusting bolt 12... When adjusting, the cable management tube 5 can be slid along the length of the adjustment hole 25 to change the distance and position of the cable management tube 5 relative to the cable reel 1, adapting to cable reels 1 of different diameters and widths. After adjustment, tightening the adjustment bolt 12 will lock the position of the cable management tube 5, ensuring that the cable 101 can always pass through the lead hole 53 accurately. The lead hole 53 opened at the outer end of the cable management tube 5 is the guide channel for the cable 101. After the free end of the cable 101 passes through the lead hole 53, the cable release direction can be neatly guided, avoiding the cable from tangling or knotting. The central support structure of the device is a screw 4. The screw 4 passes through the inner ring of the bearing 3, the rotating seat 2 and the central area of the coil 1 from top to bottom. Its bottom end extends to the bottom of the coil 1 and is fitted with a limiting plate 6 that abuts against the bottom end of the coil 1. By passing a fastening bolt 7 through the mounting hole of the limiting plate 6 and threadedly connecting it to the bottom end of the screw 4, the limiting plate 6 can be firmly locked onto the screw 4. Then, through the abutting action between the limiting plate 6 and the bottom end of the coil 1, the entire device is axially fixed on the screw 4. It is worth noting that a mounting hole 102 is opened at the bottom end of the coil 1. The limiting plate 6 and the fastening bolt 7 are both hidden inside the mounting hole 102, which not only avoids damage to the fastening structure caused by external collisions, but also ensures the flatness of the bottom of the device and improves the compactness of the overall structure. To ensure the stability of the bearing 3 on the screw 4 while maintaining its rotational flexibility, the screw 4 is externally threaded with an upper limiting bolt 8 and a lower limiting bolt 10. The upper limiting bolt 8 and the lower limiting bolt 10 are located at the upper and lower parts of the bearing 3, respectively, and their end faces abut against the inner ring of the bearing 3. Through bidirectional limiting, the inner ring of the bearing 3 is fixed at a specific position on the screw 4, preventing the bearing 3 from moving axially along the screw 4. In addition, the screw 4 is externally fitted with an upper washer 9 and a lower washer 11. The upper washer 9 is located between the upper limiting bolt 8 and the bearing 3, and the lower washer 11 is located between the coil 1 and the rotating seat 2. The upper washer 9 can disperse the pressure of the upper limiting bolt 8 on the inner ring of the bearing, avoiding excessive local stress that could damage the bearing. The lower washer 11 can reduce the rotational friction between the rotating seat 2 and the coil 1, reducing wear and improving the smoothness of rotation of the rotating seat 2. During actual wire laying operations, when the external traction equipment pulls the free end of the wire 101, the wire 101 will drive the wire guide tube 5 to generate traction force through the lead hole 53. Since the wire guide tube 5 is fixedly connected to the rotating seat 2 through the first arm plate 23, and the rotating seat 2 is connected to the outer ring of the bearing 3, under the action of traction force, the rotating seat 2 will rotate synchronously around the axis of the screw 4 with the traction direction of the wire, so that the wire guide tube 5 always faces the traction direction of the wire, realizing dynamic guidance. At the same time, the inner ring of the bearing 3 is fixed by the upper limit bolt 8 and the lower limit bolt 10, and the outer ring rotates freely with the rotating seat 2, which greatly reduces the frictional resistance during the rotation process and ensures the smoothness and continuity of the wire laying operation. The entire device realizes the functions of automatic wire guidance, adaptive wire reel specifications, and low-resistance wire laying through the coordinated cooperation of the mechanical structure, effectively improving the efficiency and stability of the wire laying operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
