[0002] Heating wire, also known as heating wire, is a conductor that generates heat by applying electricity to it. There are many types of heating wire, and in basic physics, they are referred to as resistance wire or resistance wire. Its basic structure consists of a core wire, a metal wire wrapped around the core wire, and an outer layer of insulating plastic covering the metal wire.

Therefore, designing a pay-off device that can effectively adjust the core wire tension is of great significance for improving the production efficiency and product quality of heating wire.

[0016] 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.
[0017] Example 1, as Figure 1-2As shown, a pay-off tension adjustment device comprises a workbench 1, an upper support plate 2 and a lower support plate 3 are fixedly installed above and below the side of the workbench 1 respectively, a guide column 4 is fixedly installed between the upper support plate 2 and the lower support plate 3, a first guide wheel 6 is rotatably connected to the upper side of the guide column 4 through a first installation shaft 5, a guide sleeve 7 is movably sleeved on the outer surface of the lower side of the guide column 4, and the outer surface of the guide sleeve 7 is rotatably connected to the second guide wheel 9 through a second installation shaft 8; a spring 10 is sleeved on the outer surface of the guide column 4, the upper end of the spring 10 is abutted against the first installation shaft 5, and the lower end of the spring 10 is abutted against the guide sleeve 7; a support frame 11 is fixedly installed above the workbench 1, and a third guide wheel 13 is rotatably connected to the side of the support frame 11 through a third installation shaft 12, and a pay-off wheel 14 is provided on one side of the workbench 1.
[0018] In this embodiment, the outer circumference of the first guide wheel 6 is provided with three annular guide grooves, which are guide groove A, guide groove B and guide groove C respectively, and the outer circumference of the second guide wheel 9 is provided with two annular guide grooves, which are guide groove D and guide groove E respectively.
[0019] Working principle:
[0020] During use, the wire core wound on the pay-off wheel 14 is first led out, and then the wire core is first passed around the guide groove A on the outer circumference of the first guide wheel 6, and then passed downward around the guide groove D of the second guide wheel 9, and then passed upward around the guide groove B on the outer circumference of the first guide wheel 6, and then passed downward around the guide groove E of the second guide wheel 9, and then passed upward around the guide groove C on the outer circumference of the first guide wheel 6, and then passed around the third guide wheel 13, and then the wire is delivered to the output end. By winding the wire core twice between the first guide wheel 6 and the second guide wheel 9, the tension control of the wire core itself can be guaranteed, and the stability of the wire core wound between the first guide wheel 6 and the second guide wheel 9 can be effectively guaranteed.
[0021] In this embodiment, by mounting the second guide wheel 9 on the outer side of the guide sleeve 7, which in turn slides up and down along the guide column 4, and by applying a constant downward elastic force to the guide sleeve 7 via the spring 10, the second guide wheel 9 constantly exerts a certain downward tension on the wire core. Consequently, when the wire core payout speed is too fast, the wire core tension between the first guide wheel 6 and the second guide wheel 9 is less than the elastic force of the spring 10, causing the second guide wheel 9 to slide downward due to the elastic force of the spring 10, effectively increasing the tension in the wire core between the first and second guide wheels 6 and 9. When the wire core payout speed is too slow, the wire core tension between the first and second guide wheels 6 and 9 is greater than the elastic force of the spring 10, causing the second guide wheel 9 to slide upward along the guide column 4 due to the tension in the wire core, effectively reducing the tension in the wire core between the first and second guide wheels 6 and 9.
[0022] The entire process is achieved through the combination of a spring 10, a first guide wheel 6, and a second guide wheel 9. The spring 10 provides a continuous downward elastic force on the second guide wheel 9, enabling it to slide up and down along the guide post 4 in response to changes in the wire core's payout speed. This changes the tension control applied by the second guide wheel 9 to the wire core, effectively adapting to changes in the wire core's tension. This ensures that the wire core maintains a stable tension during the payout process. The device also features a simple structure, few components, and is easy to install and maintain, reducing production costs and downtime.
[0023] Embodiment 2, as a further preferred embodiment of embodiment 1, a support base 15 is provided on the rear side of the pay-off wheel 14, a rotating shaft 16 is rotatably connected to the middle of the support base 15 through a bearing, the pay-off wheel 14 is fixedly mounted on the rotating shaft 16, the rear end of the rotating shaft 16 passes through the support base 15 and is fixedly mounted with a driving gear, which is connected to the driving shaft of the driving motor through a transmission belt. The driving shaft of the driving motor drives the rotating shaft 16 to rotate, and then the pay-off wheel 14 can be driven to rotate through the rotating shaft 16 to complete the pay-off action of the line core.
[0024] Example 3, as a further preferred embodiment of Example 1, is provided with an external thread 17 on the outer surface of the guide post 4. An adjusting screw 18 is threadedly connected to the upper surface of the guide post 4 via the external thread 17, and the upper end of the spring 10 abuts against the lower surface of the adjusting screw 18. By threading an adjusting screw 18 above the guide post 4 and abutting the upper end of the spring 10 against the adjusting screw 18, the relative position of the adjusting screw 18 on the guide post 4 can be adjusted by rotating the adjusting screw 18 according to actual needs, thereby effectively adjusting the preload force of the spring 10 to meet the pay-off requirements of wire cores of different specifications.

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.
