Description

Technical Field

[0001] This utility model relates to the field of wire bundling machine technology, and in particular to a fixing device for a copper wire reel of a wire bundling machine. Background Technology

[0002] A wire bundling machine is an auxiliary device used in the production and processing process to twist multiple individual copper wire cores together according to a specified model, so as to facilitate the coating of plastic or rubber when producing wires. The wire feeding frame is mainly used to install copper wire spools with copper wire cores wound on them. The tension of the copper wire cores on each copper wire spool installed on the wire feeding frame is adjusted by the friction belt on the tension wheel and the tension of the tension gun.

[0003] A copper wire spool is rotatably connected to the mounting beam of the wire harness machine. The copper wire spool rotates by a rotating shaft inserted at its center. An inner limit block and an outer limit block are respectively installed at both ends of the copper wire spool, limiting the spool between the inner and outer limit blocks. When the outer limit block is locked, the copper wire spool is fixedly mounted on the rotating shaft and rotates with it. When the outer limit block is removed, it can be detached from the rotating shaft.

[0004] The existing external limit block mainly relies on manual tightening to fix the copper wire spool, which is inconvenient, time-consuming and labor-intensive. Therefore, a fixing device for the copper wire spool of the wire feeding frame of the wire bundling machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing device for the copper wire reel of a wire bundling machine.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fixing device for a copper wire spool of a wire feeding frame of a wire bundling machine includes a rotating shaft, on which the copper wire spool is slidably sleeved, and an inner limiting ring is provided at the right end of the copper wire spool.

[0008] In a preferred embodiment, a fixing plate is sleeved on the rotating shaft, and the inner limiting ring is fixedly installed on the fixing plate.

[0009] A fixing mechanism is provided at the left end of the copper wire reel, and the rotating shaft passes through the fixing mechanism. The shaft end extending from the fixing mechanism is designed as a threaded end, and a locking end block is connected to the external thread of the threaded end. The locking end block abuts against the fixing mechanism. Several circumferentially distributed outer limiting blocks are provided on the side of the fixing mechanism away from the locking end block. The outer limiting blocks move toward the axis of the rotating shaft and press against the copper wire reel.

[0010] In a preferred embodiment, the fixing mechanism comprises a sleeve, a sliding ring, a mounting base, a connecting rod, an outer protrusion, a connecting plate, and an outer limiting block.

[0011] In a preferred embodiment, the sliding ring is embedded in the sleeve and slides along its axial direction. The sliding ring and the sleeve are coaxially arranged, and the rotating shaft passes through the center of the sliding ring.

[0012] In a preferred embodiment, the sliding ring has several circumferentially distributed mounting seats on its outer circumferential surface, and a connecting rod is rotatably mounted on each mounting seat.

[0013] In a preferred embodiment, the outer circumferential surface of the sleeve is provided with a plurality of circumferentially distributed protrusions, each of which corresponds to a mounting base. At least two sets of parallel connecting plates are rotatably mounted on each of the protrusions, and the other ends of the connecting plates on the same protrusion are all mounted on the same outer limit block.

[0014] In a preferred embodiment, the connecting rod on the mounting base connects its movable end to the middle position of one of the connecting plates on the corresponding external protrusion.

[0015] In a preferred technical solution, the circumferentially distributed outer limiting blocks are arranged in a ring and assembled into a complete ring.

[0016] In a preferred embodiment, a thrust ring is sleeved on the shaft of the rotating shaft, and the thrust ring contacts the sliding ring and pushes the sliding ring into the sleeve.

[0017] The beneficial effects of the utility model are:

[0018] The fixing device proposed in this solution solves the problem of inconvenient and quick fixing of the copper wire reel of the wire feeding frame. The position of the fixing mechanism is limited by the locking end block and the thrust ring on the rotating shaft. After the position of the fixing mechanism is determined, the outer limit block just abuts against the left end of the copper wire reel. With the cooperation of the inner limit ring on the right end of the copper wire reel, the copper wire reel is located between the outer limit block and the inner limit ring, and finally the position of the copper wire reel is fixed.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In this embodiment, refer to Figure 1-2 A fixing device for a copper wire reel in a wire bundling machine includes a rotating shaft 1. A copper wire reel 3 is slidably mounted on the rotating shaft 1. An inner limiting ring 4 is provided at the right end of the copper wire reel 3. A fixing plate 5 is sleeved on the rotating shaft 1, and the inner limiting ring 4 is fixedly mounted on the fixing plate 5. The function of the fixing plate 5 is to determine the position of the inner limiting ring 4. When the copper wire reel 3 slides into the rotating shaft 1, the right end of the copper wire reel 3 pushes against the inner limiting ring 4 and stops.

[0024] The left end of the copper wire spool 3 is provided with a fixing mechanism 6. The rotating shaft 1 passes through the fixing mechanism 6. The shaft end of the rotating shaft 1 extending out of the fixing mechanism 6 is designed as a threaded end 2. The external thread of the threaded end 2 is connected to a locking end block 7.

[0025] Refer to the instruction manual. Figure 2 The structure of the fixing mechanism 6 is described in the attached diagram. Figure 2 As shown, the fixing mechanism 6 consists of a sleeve 8, a sliding ring 9, a mounting base 10, a connecting rod 11, an outer protrusion 12, a connecting plate 13, and an outer limiting block 14.

[0026] The sliding ring 9 is built into the sleeve 8 and can slide freely along its axis. The sliding ring 9 and the sleeve 8 are coaxially arranged, and the rotating shaft 1 passes through the center of the sliding ring 9.

[0027] The structure of three parts needs special explanation:

[0028] The sliding ring 9 has several circumferentially distributed mounting seats 10 on its circumferential surface outside the sleeve 8, and a connecting rod 11 is rotatably mounted on each mounting seat 10.

[0029] The outer circumferential surface of the sleeve 8 is provided with a number of circumferentially distributed external protrusions 12. The external protrusions 12 are provided in a one-to-one correspondence with the mounting base 10. At least two sets of parallel connecting plates 13 are rotatably mounted on the external protrusions 12. The other end of the connecting plate 13 provided on the same external protrusion 12 is mounted on the same external limit block 14.

[0030] The connecting rod 11 on the mounting base 10 connects its movable end to the middle position of one of the connecting plates 13 on the corresponding external protrusion 12.

[0031] The parallel connecting plate 13 is designed to ensure that the movement path of the outer limit block 14 is along the radial direction of the rotating shaft 1.

[0032] A thrust ring 15 is fitted onto the shaft of the rotating shaft 1. When installing the fixing mechanism 6, the operator inserts the sleeve 8 and the sliding ring 9 from the left end of the rotating shaft 1, and then pushes the sleeve 8 to the right. When the sliding ring 9 contacts the thrust ring 15, since the thrust ring 15 is fixed in position, the sliding ring 9 will be pushed back into the sleeve 8. As the sliding ring 9 slides into the sleeve 8, the connecting rods 11 in a ring pull on each connecting plate 13, causing the outer limiting block 14, which is circumferentially one ring in diameter, to move radially toward the axis of the rotating shaft 1 and press against the rotating shaft 1.

[0033] Here, the circumferentially distributed outer limiting blocks 14 are arranged in a ring and can be assembled into a complete ring. The copper wire disc 3 is located between the outer limiting blocks 14 and the inner limiting ring 4. At this time, the fixing mechanism 6 can also slide along the axis of the rotating shaft 1. In order to ensure that the position of the copper wire disc 3 is fixed by the outer limiting blocks 14, the locking end block 7 is screwed into the threaded end 2. As the locking end block 7 is screwed in, the fixing mechanism 6 will be gradually pushed to the right until the final position.

[0034] In this design, the locking end block 7 and the thrust ring 15 on the rotating shaft 1 are used to limit the position of the fixing mechanism 6. After the position of the fixing mechanism 6 is determined, the outer limit block 14 abuts against the left end of the copper wire disc 3, and works in conjunction with the inner limit ring 4 on the right end of the copper wire disc 3 to finally fix the position of the copper wire disc 3. When the rotating shaft 1 rotates, it can be ensured that the copper wire disc 3, the inner limit ring 4, and the fixing mechanism 6 rotate synchronously with the rotating shaft 1.

[0035] Finally, when disassembling the copper wire reel 3, simply remove the locking end block 7, and then slide the fixing mechanism 6 outward along the rotating shaft 1 to allow the outer limit block 14 to disengage from the copper wire reel 3, thereby quickly removing the copper wire reel 3.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
