Description

Technical Field

[0001] This utility model relates to the technical field of steel wire rewinding machines, and in particular to a steel wire rewinding machine. Background Technology

[0002] A wire rewinding machine is an industrial device used to rewind and arrange steel wires. It is mainly used to rewind messy, loose or large coils of steel wires into small coils that are neatly arranged and have uniform tension, in order to meet the needs of subsequent processing, transportation or storage.

[0003] In a wire rewinding machine, the drive shaft is the core power component used to drive the take-up reel to rotate, so that the wire is evenly wound on the take-up reel at a set speed and tension. The drive shaft is usually equipped with a frequency converter or servo control system to adapt to the winding requirements of wires of different diameters and materials, ensuring that the wound wire is tight and flat after winding, and avoiding looseness or overlapping.

[0004] Currently, the drive shaft of the rewinding machine is generally fixed to the take-up reel with bolts. After the wire is wound, the bolts need to be removed to take off the full take-up reel and replace it with an empty reel for re-fixing. Although the bolt connection has high structural stability, the frequent disassembly and assembly operations are not only time-consuming and labor-intensive, but also easily lead to thread wear or loosening, which seriously affects the working efficiency of the equipment. Therefore, a wire rewinding machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wire rewinding machine, which aims to improve the problem mentioned in the prior art that "the disassembly and assembly between the drive shaft and the take-up reel of the rewinding machine is too cumbersome, affecting work efficiency".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel wire rewinding machine, comprising a machine body, a drive shaft rotatably connected to the side wall of the machine body, a spline block fixedly connected to the outer wall of the drive shaft, a winding disc sleeved on the outer wall of the drive shaft, a spline groove that fits with the spline block on the inner wall of the winding disc, and a positioning mechanism and a protective mechanism provided on the side wall of the machine body.

[0007] The positioning mechanism includes a rotating rod rotatably connected to the side wall of the machine body. A positioning rod for positioning the winding disc is slidably connected to the inner wall of the rotating rod. A threaded rod is rotatably connected through the inner wall of the rotating rod. A pedal is slidably connected to the side wall of the machine body. A connecting rod is hinged to the top of the pedal. A protrusion is fixedly connected to the outer wall of the rotating rod. A torsion spring is provided at the connection between the rotating rod and the machine body.

[0008] As a further description of the above technical solution:

[0009] The protective mechanism includes a protective cover, which is slidably connected to the side wall of the machine body, and a connecting rod is hinged to the outer wall of the protective cover.

[0010] As a further description of the above technical solution:

[0011] The side wall of the machine body is hinged with a swing arm for pushing and pulling the connecting rod, and the swing arm has a through groove.

[0012] As a further description of the above technical solution:

[0013] An L-rod is fixedly connected to the top of the pedal, and the end of the L-rod away from the pedal is attached to the inner wall of the through groove.

[0014] As a further description of the above technical solution:

[0015] The end of the connecting rod furthest from the protective cover is hinged to the left end of the swing arm.

[0016] As a further description of the above technical solution:

[0017] The end of the connecting rod furthest from the pedal is hinged to the protrusion.

[0018] As a further description of the above technical solution:

[0019] A knob is fixedly connected to the end of the threaded rod away from the machine body and extending to the outside of the rotating rod. The threaded rod is threadedly connected to the positioning rod.

[0020] As a further description of the above technical solution:

[0021] The drive shaft has a convex cross-section, with one side of the winding disc fitting against the outer wall of the drive shaft and the other side of the winding disc fitting against the positioning rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the positioning mechanism allows for quick assembly and disassembly of the winding reel, enabling rapid replacement of full and empty reels. Compared to the traditional bolt installation method, this is not only more convenient to use, but also allows for positioning of winding reels of different lengths, greatly improving the overall convenience of the equipment and thus effectively increasing work efficiency.

[0024] 2. In this utility model, the protective mechanism can cover the winding disc during the winding of the steel wire. When the steel wire breaks accidentally during the winding process, the protective cover can block the broken steel wire, preventing the steel wire from jumping up and accidentally injuring the surrounding staff, thereby avoiding the occurrence of safety accidents.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a wire rewinding machine, including a machine body 1. The rewinding machine is existing technology, so it will not be described in detail here. A drive shaft 2 is rotatably connected to the side wall of the machine body 1. The drive shaft 2 is fixedly connected to the output end of a servo motor inside the machine body 1. The cross-section of the drive shaft 2 is convex. By setting the drive shaft 2 to a convex cross-section, the winding disc 4 can be effectively restricted. A spline block 3 is fixedly connected to the outer wall of the drive shaft 2. The winding disc 4 is sleeved on the outer wall of the drive shaft 2. One side of the winding disc 4 is in contact with the outer wall of the drive shaft 2, and the other side of the winding disc 4 is in contact with the positioning rod 62. The inner wall of the winding disc 4 is provided with a spline groove 5 that matches the spline block 3. The drive shaft 2 and the winding disc 4 can rotate synchronously by the spline groove 5 and the spline block 3 matching each other. The side wall of the machine body 1 is provided with a positioning mechanism 6 and a protective mechanism 7.

[0033] Reference Figure 2 and Figure 4The positioning mechanism 6 includes a rotating rod 61, which is rotatably connected to the side wall of the machine body 1. A positioning rod 62 for positioning the winding disc 4 is slidably connected to the inner wall of the rotating rod 61. The rotating rod 61, in conjunction with the positioning rod 62, can axially limit the winding disc 4, thereby limiting it to the outer wall of the drive shaft 2. A threaded rod 63 is rotatably connected through the inner wall of the rotating rod 61. A knob 64 is fixedly connected to the end of the threaded rod 63 away from the machine body 1 and extending to the outside of the rotating rod 61. The knob 64 allows for easy rotation of the threaded rod 63. The threaded rod 63 is threadedly connected to the positioning rod 62. The rotation of rod 63 can cause the positioning rod 62, which is threadedly connected to it, to slide on the inner wall of rotating rod 61. A pedal 65 is slidably connected to the side wall of the machine body 1. A connecting rod 66 is hinged to the top of the pedal 65. A protrusion 67 is fixedly connected to the outer wall of rotating rod 61. The end of the connecting rod 66 away from the pedal 65 is hinged to the protrusion 67. When the pedal 65 slides on the side wall of the machine body 1, it can drive the rotating rod 61 to rotate on the side wall of the machine body 1 in conjunction with the connecting rod 66 and the protrusion 67. A torsion spring 68 is provided at the connection between the rotating rod 61 and the machine body 1. The elasticity of the torsion spring 68 can drive the rotating rod 61 to rotate and reset on the side wall of the machine body 1.

[0034] Reference Figure 2 and Figure 4 The protective mechanism 7 includes a protective cover 71, which is slidably connected to the side wall of the machine body 1. Sliding the protective cover 71 upwards exposes the winding disc 4 outside the drive shaft 2, facilitating disassembly of the winding disc 4. Sliding the protective cover 71 downwards covers the winding disc 4 outside the drive shaft 2, preventing accidental breakage of the steel wire during winding and thus preventing injury to nearby workers. A connecting rod 72 is hinged to the outer wall of the protective cover 71, and a swing arm 7 is hinged to the side wall of the machine body 1 for pushing and pulling the connecting rod 72. 3. The end of the connecting rod 72 away from the protective cover 71 is hinged to the left end of the swing rod 73. The rotation of the swing rod 73, in conjunction with the connecting rod 72, can drive the protective cover 71 to slide up and down on the side wall of the machine body 1. A through groove 74 is provided on the swing rod 73. An L rod 75 is fixedly connected to the top of the pedal 65. The end of the L rod 75 away from the pedal 65 is attached to the inner wall of the through groove 74. When the pedal 65 slides on the side wall of the machine body 1, the L rod 75 and the through groove 74 can drive the swing rod 73 to rotate on the side wall of the machine body 1.

[0035] Working principle: When the winding reel 4 is full and needs to be disassembled, press down on the pedal 65 to make it slide down on the side wall of the machine body 1. As the pedal 65 slides down, it pulls down the connecting rod 66, causing the connecting rod 66 to pull down the protrusion 67. At this time, the protrusion 67 will swing down around the rotating rod 61 and drive the rotating rod 61 to rotate on the side wall of the machine body 1. As the rotating rod 61 rotates, it will squeeze the torsion spring 68 and drive the positioning rod 62 to swing down around the rotating rod 61. This will separate the positioning rod 62 from the winding reel 4. At this time, the winding reel 4 can be directly removed from the drive shaft 2.

[0036] After the full winding disc 4 is removed from the drive shaft 2, the empty winding disc 4 is placed on the outer wall of the drive shaft 2 so that it fits against the drive shaft 2, and the spline groove 5 on the inner wall of the winding disc 4 engages with the spline block 3. At this time, the pedal 65 can be released. The elasticity of the torsion spring 68 can drive the protrusion 67 to swing upward and reset. At the same time, the upward swing of the protrusion 67, together with the connecting rod 66, can drive the pedal 65 to slide upward and reset on the side wall of the machine body 1. Simultaneously, under the elasticity of the torsion spring 68, the rotating rod 61 can be driven to rotate and reset. After the rotating rod 61 rotates and resets, it will drive the positioning rod 62 to fit against the outer wall of the winding disc 4 again. At this time, the positioning rod 62 can axially limit the winding disc 4 to the outer wall of the drive shaft 2, thus completing the installation of the winding disc 4. Compared with the traditional bolt installation method, it is more convenient to use and helps to improve work efficiency.

[0037] Rotating the threaded rod 63 by knob 64 causes the threaded rod 63 to slide on the inner wall of the rotating rod 61, thereby adjusting the distance between the positioning rod 62 and the machine body 1. This allows the positioning rod 62 to position winding discs 4 of different lengths, improving the practicality of the equipment.

[0038] As the pedal 65 slides downward, it will drive the L-bar 75 to move downward simultaneously. At this time, the L-bar 75 will move against the inner wall of the through groove 74 and pull the swing arm 73 downward, causing the swing arm 73 to rotate on the side wall of the machine body 1. As the swing arm 73 rotates, it will push the connecting rod 72 upward, causing the connecting rod 72 to push the protective cover 71 upward. At this time, the protective cover 71 will slide upward on the side wall of the machine body 1, thereby exposing the winding disc 4 outside the drive shaft 2, making it convenient to disassemble the winding disc 4.

[0039] When the pedal 65 slides upward to reset, it will drive the L rod 75 to move upward synchronously. At this time, the L rod 75 will move against the inner wall of the through groove 74 and push the swing arm 73 upward, so that the swing arm 73 rotates on the side wall of the machine body 1. While the swing arm 73 is rotating, it will pull the connecting rod 72 downward, so that the connecting rod 72 pulls the protective cover 71 downward. At this time, the protective cover 71 will slide downward on the side wall of the machine body 1. By sliding the protective cover 71 downward, the winding disc 4 outside the drive shaft 2 can be covered. When the steel wire breaks accidentally during the winding process, the protective cover 71 can block the broken steel wire and prevent the steel wire from jumping up and accidentally injuring the surrounding staff.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
