[0002] Heating wire is a component that generates heat when connected to an electrical source, achieving a specific purpose. Depending on the raw materials used during the production process, heating wire can be categorized into various types, including nickel-chromium wire and iron-chromium-aluminum wire. During heating wire production and processing, it is typically wound and stored using a reel.

[0003] However, when currently used, most existing winding devices directly wind the heating wire around the winding wheel, but are unable to adjust the tension of the heating wire during winding, which will cause the heating wire to be unevenly tight after winding, which not only affects the appearance, but may also cause breakage or performance degradation during use due to uneven tension.

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0020] Example 1, as Figure 1-3 As shown, a take-up tension adjustment device for heating wires includes a support platform 1, a bearing seat 2 is fixedly installed on the upper surface of the support platform 1, a rotating shaft 3 is rotatably connected to the middle of the bearing seat 2, the front end of the rotating shaft 3 passes through the bearing seat 2 and is fixedly connected to the take-up wheel 4; the rear end of the rotating shaft 3 passes through the bearing seat 2 and is sequentially installed with a friction wheel 5, a friction pad 7, a transmission pressure wheel 6, a spring 8, a pressure pad 9 and an adjusting nut 10, wherein the friction wheel 5 is coaxially fixedly installed on the rotating shaft 3 near the bearing seat 2, and the rear side of the friction wheel 5 is provided with a A transmission pressure wheel 6 is provided, which is movably sleeved on the outer surface of the rotating shaft 3. A friction pad 7 is provided between the transmission pressure wheel 6 and the friction wheel 5. A spring 8 is provided on the rear side of the transmission pressure wheel 6, which is sleeved on the outer surface of the rotating shaft 3. One end of the spring 8 is in contact with the rear side of the transmission pressure wheel 6, and the other end of the spring 8 is in contact with the pressure pad 9. An adjusting nut 10 is provided on the rear side of the pressure pad 9, and the adjusting nut 10 is threadedly connected to the outer surface of the rotating shaft 3; the transmission pressure wheel 6 is connected to the driving shaft of the driving motor through a first transmission belt 11;

[0021] A workbench 12 is provided on the side of the support platform 1, and two screw bearing seats 13 are installed on the workbench 12. A screw 14 is rotatably connected between the two screw bearing seats 13. The screw 14 is arranged parallel to the rotating shaft 3. The surface of the screw 14 is provided with two rectangular thread grooves with the same pitch of left and right rotation. The two rectangular thread grooves are connected end to end at both ends of the screw to form a completely closed spiral groove. The outer surface of the screw 14 is connected to the screw slider 15 through the spiral groove thread, so that when the screw 14 rotates, the sliding tongue on the screw slider 15 and the spiral groove form a sliding pair. When the screw slider 15 moves to the end point of the spiral groove, the sliding tongue will automatically enter the thread groove of the other rotation direction, thereby realizing the reciprocating movement effect of the screw slider 15. A support column 16 is fixedly installed above the screw slider 15, and a guide wheel 17 is rotatably installed above the front side of the support column 16 through the installation shaft. The guide wheel 17 corresponds to the take-up wheel 4 on the left and right; the rear end of the screw 14 passes through the screw bearing seat 13 and is connected to the driving mechanism for driving the screw 14 to rotate.

[0022] Working principle:

[0023] During use, the heating wire produced by the previous process is first introduced onto the guide wheel 17, passed around the guide wheel 17, and then wound onto the take-up wheel 4. The drive shaft of the driving motor then drives the transmission pressure wheel 6 to rotate. The elastic pressure of the spring 8 causes the transmission pressure wheel 6 to contact the friction wheel 5 via the friction pad 7. Therefore, through the sliding friction between the transmission pressure wheel 6, the friction pad 7, and the friction wheel 5, the rotation of the transmission pressure wheel 6 drives the friction wheel 5 to rotate, which in turn drives the rotating shaft 3 to rotate, and then drives the take-up wheel 4 to rotate and take up the wire. At the same time, the driving mechanism drives the lead screw 14 to rotate, which in turn drives the lead screw slider 15 to move back and forth along the axial direction of the lead screw 14, thereby driving the guide wheel 17 to move back and forth along the axial direction of the lead screw 14, thereby effectively ensuring that the heating wire is evenly and tightly wound around the take-up wheel 4 in a spiral shape. This allows the heating wire to be neatly arranged and tightly wound on the take-up wheel 4, thereby effectively improving the product's appearance quality and performance.

[0024] When the rotation speed of the take-up wheel 4 is too slow, the compression degree of the spring 8 can be adjusted by rotating the adjusting nut 10, and then the pressure pad 9 can be used to adjust the elastic pressure of the spring 8 on the transmission pressure wheel 6, thereby effectively increasing the friction between the transmission pressure wheel 6, the friction pad 7 and the friction wheel 5, and then when the transmission pressure wheel 6 rotates, it can drive the friction wheel 5 to rotate faster, thereby effectively increasing the rotation speed of the rotating shaft 3 and the take-up wheel 4, and then effectively increasing the take-up tension of the heating wire.

[0025] Similarly, when the rotation speed of the take-up wheel 4 is too fast, the adjusting nut 10 can be rotated in the opposite direction to move the adjusting nut 10 away from the spring 8, thereby reducing the elastic pressure of the spring 8 on the transmission pressure wheel 6, thereby effectively reducing the friction between the transmission pressure wheel 6, the friction pad 7 and the friction wheel 5, thereby reducing the rotation speed of the friction wheel 5, and then effectively reducing the rotation speed of the rotating shaft 3 and the take-up wheel 4, so as to avoid the problem of excessive tension of the heating wire and breakage due to the excessive rotation speed of the take-up wheel 4.

[0026] The present invention sequentially installs a spring 8, a transmission pressure wheel 6, a friction pad 7, a friction wheel 5, and a take-up wheel 4 on a rotating shaft 3 to form a system capable of adjusting friction as needed. By adjusting the elastic pressure of the spring 8, the friction between the transmission pressure wheel 6, the friction pad 7, and the friction wheel 5 is varied, thereby indirectly controlling the rotational speed of the take-up wheel 4 and thereby adjusting the take-up tension of the heating wire. This allows for precise adjustment of the take-up tension to ensure uniform winding of the heating wire and reduce quality issues caused by uneven tension. Furthermore, the present invention can flexibly adjust the tension based on the material, diameter, and other characteristics of the heating wire, thereby adapting to various heating wire winding specifications.

[0027] In the second embodiment, as a further preferred embodiment of the first embodiment, two bearing seats 2 are provided, and the rotating shaft 3 passes through the two bearing seats 2 in sequence and is rotatably connected to the two bearing seats 2. The two bearing seats 2 jointly support the rotating shaft 3 to ensure the stability of the rotating shaft 3 during rotation.

[0028] Embodiment 3, as a further preferred embodiment of embodiment 1, is characterized in that a driving wheel 18 is fixedly mounted on the rotating shaft 3 and is located between the friction wheel 5 and the bearing seat 2. The rear end of the lead screw 14 passes through the lead screw bearing seat 13 and is fixedly mounted with a driven wheel 19. The driving wheel 18 is connected to the driven wheel 19 via a second transmission belt 20. Therefore, when the friction wheel 5 is rotated by the rotation of the transmission pressure wheel 6, and the rotating shaft 3 is then driven to rotate, the driving wheel 18 rotates synchronously with the rotating shaft 3, thereby driving the driven wheel 19 to rotate synchronously via the second transmission belt 20, and then driving the lead screw 14 to rotate via the driven wheel 19. This drives the lead screw slider 15 and the guide wheel 17 to move back and forth along the axial direction of the lead screw 14, so that the heating wire can be evenly and tightly wound around the take-up wheel 4 in a spiral shape.

[0029] In this embodiment, the number of teeth on the outer circumference of the driving wheel 18 and the driven wheel 19 can be set to effectively control the tightness of the spiral arrangement of the heating wires, and the entire device only needs to rely on one drive motor to achieve the synchronous rotation effect of the rotating shaft 3 and the screw 14.

[0030] Embodiment 4, as a further preferred embodiment of embodiment 1, a guide rod 21 is fixedly installed between the two screw bearing seats 13. The guide rod 21 is arranged parallel to the screw 14. A guide through hole is opened on the screw slider 15. The screw slider 15 is slidably connected to the outer surface of the guide rod 21 through the guide through hole. The guide rod 21 guides the screw slider 15 during movement, thereby ensuring the stability of the screw slider 15 during sliding.

[0031] Embodiment 5, as a further preferred embodiment of embodiment 1, the front end of the rotating shaft 3 is connected to a locking nut 22 through a thread, and the locking nut 22 abuts against the front side of the take-up reel 4. Therefore, when disassembling the take-up reel 4, it is only necessary to remove the locking nut 22 from the front end of the rotating shaft 3, and then pull the take-up reel 4 out of the rotating shaft 3. Similarly, when the take-up reel 4 needs to be installed, it is only necessary to insert the take-up reel 4 onto the rotating shaft 3, and then tighten the locking nut 22 so that the locking nut 22 tightly abuts against the front side of the take-up reel 4, thereby achieving the installation and fixing effect between the take-up reel 4 and the rotating shaft 3.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
