Abstract
Description
Technical Field
[0001] This utility model relates to the field of tension adjustment technology for winding machines, and in particular to a winding machine with tension adjustment. Background Technology
[0002] A winding machine is a mechanical device used to wind wires (such as metal wires, electrical wires, yarns, fibers, etc.) onto a winding spool, bobbin, or mold according to a specific pattern. It is widely used in industries such as electronics, electrical engineering, textiles, automobiles, and aerospace.
[0003] However, in the existing technology, when the sensor malfunctions during the use of the winding machine, it cannot accurately detect the actual tension value. As a result, the control system cannot adjust the tension according to the actual situation. If the tension is too high and cannot be adjusted, the wound coil will be subjected to excessive tension, which may cause changes in the shape of the coil, such as elliptical or twisted deformation. This will affect the installation and use of the coil in the equipment, and in severe cases, it may even prevent the coil from working properly. Excessive tension will also cause the wire to bear excessive tension, which can easily cause wear and scratches on the surface of the wire, and may even damage the internal structure of the wire. On the other hand, if the tension is too low, the wire will become loose. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art that when the sensor malfunctions, it cannot accurately detect the actual tension value, which leads to the control system being unable to adjust the tension according to the actual situation. Excessive tension that cannot be adjusted will cause the wound coil to be subjected to excessive tension. Therefore, this invention proposes a winding machine with tension adjustment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winding machine with tension adjustment, comprising a winding machine body, a positioning plate, a rotating rod, and a limiting wheel. The positioning plate is fixedly installed on the top of the winding machine body, and the limiting wheel is fixedly installed on the end of the rotating rod. The rotating rod is rotatably connected to the positioning plate. An adjustment mechanism is fixedly installed on the top of the winding machine body. The adjustment mechanism includes a positioning rod, a receiving cylinder, a contact head, a tension spring, and an adjustment block. One end of the receiving cylinder is fixedly connected to the positioning rod. The adjustment block is threaded onto the outer wall of the receiving cylinder. The inner wall of the adjustment block is fixedly connected to one end of the tension spring. The other end of the tension spring is fixedly connected to the contact head. The contact head is slidably connected inside the receiving cylinder.
[0006] Preferably, the other end of the contact head is rotatably connected to a limit ring, which is sleeved on the outer wall of the rotating rod.
[0007] Preferably, one end of the positioning rod is fixedly connected to a guide rod, and one end of the guide rod is inserted into the inside of the contact head.
[0008] Preferably, the tension spring is sleeved on the outer wall of the guide rod.
[0009] Preferably, a limiting rod is fixedly installed on the inner wall of the receiving cylinder, and one end of the limiting rod is fixedly connected to the guide rod.
[0010] Preferably, grooves are provided on both sides of the contact head, the limiting rod is located inside the groove, and an annular protrusion is fixedly installed at the edge of the contact head, with the groove penetrating the annular protrusion.
[0011] Preferably, a limit nut is threaded onto the outer wall of the receiving cylinder, and the limit nut is located on one side of the adjusting block.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, the elastic strength of the tension spring can be adjusted by rotating the adjusting block. When the tension spring is in a compressed state, the rotating rod needs to use more force to push the contact head. When the tension spring is in a released state, the rotating rod can easily push the contact head. By adjusting the position of the adjusting block, the elastic strength can be controlled, thereby limiting the rotation range of the rotating rod and realizing the adjustment of tension to ensure that the wire is not damaged, while ensuring the winding efficiency.
[0014] 2. In this utility model, an annular protrusion is provided to prevent the contact head from detaching from the receiving cylinder, thus ensuring the stability of the contact head. At the same time, a limiting rod is provided inside the receiving cylinder. The limiting rod is located in the groove, which can determine the movement path of the contact head.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a winding machine with tension adjustment, including a winding machine body 1, a positioning plate 2, a rotating rod 3, and a limiting wheel 4. The positioning plate 2 is fixedly installed on the top of the winding machine body 1, and the limiting wheel 4 is fixedly installed on the end of the rotating rod 3. The rotating rod 3 is rotatably connected to the positioning plate 2. An adjustment mechanism 5 is fixedly installed on the top of the winding machine body 1. The adjustment mechanism 5 includes a positioning rod 51, a receiving cylinder 52, a contact head 53, a tension spring 59, and an adjustment block 55. One end of the receiving cylinder 52 is fixedly connected to the positioning rod 51. The adjustment block 55 is threadedly installed on the outer wall of the receiving cylinder 52. The inner wall of the adjustment block 55 is fixedly connected to one end of the tension spring 59. The other end of the tension spring 59 is fixedly connected to the contact head 53. The contact head 53 is slidably connected inside the receiving cylinder 52. The other end of the contact head 53 is rotatably connected to a limiting ring 54, which is sleeved on the outer wall of the rotating rod 3.
[0023] The specific settings and functions of this embodiment are described below. The positioning plate 2 is installed on the top of the winding machine body 1 to determine the position of the rotating rod 3, while the limiting wheel 4 is used to determine the position of the wire. In use, the wire overlaps the surface of the limiting wheel 4, and the other end is wound around the take-up rod of the winding machine body 1. During the winding process, the pressure of the wire will push the rotating rod 3. At this time, the adjustment mechanism 5 can limit the rotation range of the rotating rod 3.
[0024] The tension spring 59 is connected to the contact head 53. The limiting ring 54 at the top of the contact head 53 is sleeved on the rotating rod 3. When the rotating rod 3 rotates, it pushes the contact head 53 through the limiting ring 54 to exert pressure on the tension spring 59. The other end of the tension spring 59 is connected to the adjusting block 55. In use, rotating the adjusting block 55 can move it along the direction of the receiving cylinder 52. When it approaches the contact head 53, it will compress the tension spring 59. When it moves away from the contact head 53, it will release the tension spring 59. When the tension spring 59 is in the compressed state, the rotating rod 3 needs to use more force to push the contact head 53. However, since the force on the rotating rod 3 is generated by the wire, this tension is stable within a fixed range. When the tension spring 59 is in the released state, the rotating rod 3 can easily push the contact head 53. The strength of the spring force can be controlled by adjusting the position of the adjusting block 55, thereby limiting the rotation range of the rotating rod 3 and realizing the adjustment of tension.
[0025] Example 2: Figure 2 and Figure 4 As shown, one end of the positioning rod 51 is fixedly connected to the guide rod 510, and one end of the guide rod 510 is inserted into the inside of the contact head 53. The tension spring 59 is sleeved on the outer wall of the guide rod 510. A limit rod 57 is fixedly installed on the inner wall of the receiving cylinder 52. One end of the limit rod 57 is fixedly connected to the guide rod 510. Grooves 58 are provided on both sides of the contact head 53. The limit rod 57 is located inside the groove 58. An annular protrusion 511 is fixedly installed at the edge of the contact head 53. The groove 58 passes through the annular protrusion 511. A limit nut 56 is threadedly connected to the outer wall of the receiving cylinder 52. The limit nut 56 is located on one side of the adjusting block 55.
[0026] The overall effect of this embodiment is that the annular protrusion 511 at the edge of the contact head 53 overlaps the inner wall of the receiving cylinder 52, which can determine the position of the contact head 53 and prevent it from detaching from the receiving cylinder 52. The limiting nut 56 is used to determine the position of the adjusting block 55 and prevent it from being displaced. The presence of the limiting rod 57 can determine the movement path of the contact head 53 and prevent it from rotating. During its movement, it will compress the tension spring 59 and insert it into the guide rod 510. A groove 58 is provided on the contact head 53 to accommodate the limiting rod 57, and the groove 58 also passes through the annular protrusion 511, so it will not affect the movement of the contact head 53.
[0027] The usage and working principle of this device are as follows: When in use, the wire is laid on the surface of the limiting wheel 4, and the other end is wound around the take-up rod of the winding machine body 1. The limiting wheel 4 is located at the end of the rotating rod 3. During the winding process, the pressure of the wire will push the rotating rod 3 to ensure that the wire is not too tight. The adjustment mechanism 5 can limit the rotation range of the rotating rod 3.
[0028] The adjusting mechanism 5 uses the elastic force of the tension spring 59 to support the rotating rod 3. The strength of the elastic force of the tension spring 59 is controlled by the adjusting block 55. Rotating the adjusting block 55 can move it along the direction of the receiving cylinder 52. When it approaches the contact head 53, it will compress the tension spring 59. At this time, the elastic force of the tension spring 59 will increase, so that the rotating rod 3 needs to use more force to push the contact head 53, thereby limiting the rotation range of the rotating rod 3. When the adjusting block 55 moves away from the contact head 53, it will release the tension spring 59. The rotating rod 3 only needs to use a small force to push the contact head 53. However, since the force on the rotating rod 3 is generated by the pulling of the wire when the winding machine body 1 winds the wire, this tension is stable within a fixed range. Only by adjusting the position of the adjusting block 55 can the strength of the elastic force be controlled, thereby limiting the rotation range of the rotating rod 3 and realizing the adjustment of tension.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
