Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: like Figures 1-6As shown, a winding machine for producing mesh electric heating mats includes a base 1, a winding structure 2 mounted on the base 1, and a winding drum sleeved on the winding structure 2. A drive structure for rotating the winding structure 2 is located on the side of the winding structure 2. Activating the drive structure rotates the winding structure 2, which in turn rotates the winding drum 25 to wind up the mesh electric heating mat. A collecting plate 3 is fixedly mounted on the base 1. The winding structure 2 includes a limiting sleeve 14 and a positioning rod 15. The limiting sleeve 14 is rotatably mounted on the collecting plate 3, and the positioning rod 15 is fixed. An adjustable support structure 17 is installed within the limiting sleeve 14 and the positioning rod 15 to provide limiting support for winding drums 25 of different sizes, facilitating their winding. The support structure 17 includes a positioning ring 35, an adjusting plate 21, a transmission plate 22, a support block 23, and a threaded sleeve 20. The positioning ring 35 is fixedly installed within the positioning rod 15. Several adjusting plates 21 are provided; in this embodiment, four are provided. The adjusting plates 21 are equidistantly arranged on the positioning ring 35, with one end of the adjusting plate 21 rotatably connected to the positioning ring 35, and the other end... The end is fixedly connected to the support block 23. One end of the transmission plate 22 is rotatably connected to the adjusting plate 21, and the other end is rotatably connected to the threaded sleeve 20. Several adjusting grooves 16 are equidistantly provided on the positioning rod 15. The adjusting plate 21 is slidably disposed in the adjusting groove 16. The support block 23 is disposed outside the adjusting groove 16. A movable rod 18 is rotatably disposed inside the adjusting plate 21. A threaded adjusting area 19 is provided on the movable rod 18. The threaded sleeve 20 is threaded onto the threaded adjusting area 19. The take-up drum 25 is sleeved on the positioning rod 15, and the movable rod 18 is rotated. The threaded sleeve 20 moves, the threaded sleeve 20 pushes the transmission plate 22 to move, the transmission plate 22 pushes the adjusting plate 21 to rotate, thereby lifting the support block 23. Several support blocks 23 abut against the inner ring of the winding drum 25 to achieve the limiting of winding drums 25 of different sizes; the end of the movable rod 18 is slidably provided with a locking block 34, and the end of the positioning rod 15 is provided with a locking groove 33. After the movable rod 18 is adjusted, the locking block 34 is pressed until the locking block 34 engages with the locking groove 33, thereby achieving the limiting of the movable rod 18 and the positioning rod 15; As one embodiment of this invention, the drive structure for driving the winding structure 2 to rotate, provided on the side of the winding structure 2, includes a drive wheel 6, a driven wheel 7, and a transmission sprocket 8. A first drive motor 5 is fixedly installed on the side of the base 1. The output shaft of the first drive motor 5 is fixedly connected to the drive wheel 6. The driven wheel 7 is rotatably disposed on the side of the collecting plate 3. One end of the limiting sleeve 14 is fixedly connected to the driven wheel 7. The transmission sprocket 8 is sleeved on the drive wheel 6 and the driven wheel 7. When the first drive motor 5 is started, the drive wheel 6 is driven to rotate. Through the transmission of the transmission sprocket 8, the driven wheel 7 is driven to rotate, thereby driving the winding structure 2 to rotate and driving the winding drum 25 to rotate, thus realizing winding. As one embodiment of this example, a pair of first upright plates 10 are fixedly provided on the base 1, and an adjusting roller 12 is rotatably provided between the first upright plates 10 to facilitate the guidance of the mesh electric heating mat. A pair of second upright plates 9 are fixedly provided on the base 1, and a pair of pressure rollers 11 are rotatably provided between the second upright plates 9. When winding, the mesh electric heating mat is pulled out from between the pair of pressure rollers 11 and rotated around the winding drum 25. As one embodiment of this invention, two pairs of casters 13 are provided below the base 1. The casters 13 can be self-locking, which facilitates the movement of the device. A push plate 4 is fixedly provided on the side of the base 1.

[0021] Example 2: like Figures 1-7 As shown, a winding machine for producing mesh electric heating mats includes a bidirectional screw 26 added to the base 1 to increase the stability of the winding drum 25. The bidirectional screw 26 is rotatably mounted on the base 1. A second drive motor 24 is fixedly mounted on the side of the base 1, and the output shaft of the second drive motor 24 is fixedly connected to the bidirectional screw 26. Transmission blocks 27 are symmetrically arranged on the opposite threaded areas of the bidirectional screw 26. A limit plate 28 is fixedly mounted on the transmission block 27, and a slide rod 30 is slidably mounted on the limit plate 28. A limit bolt 29 is provided between the slide rod 30 and the limit plate 28 to limit the slide rod 30 on the limit plate 28. A first stop block 31 and a second stop block 32 are fixedly mounted at both ends of the slide rod 30. The pair of first stops block 31 are used to limit the two ends of the winding drum 25. The second stop 32 is set on both sides of the pressure roller 11 to adjust the position of the mesh heating pad passing through the pressure roller 11, making its winding more stable. The second drive motor 24 is started to drive the bidirectional screw 26 to rotate, thereby driving a pair of limit plates 28 to move towards each other, realizing the limit of the two ends of the winding drum 25 by a pair of first stops 31, preventing the mesh heating pad from running off-center during winding. After winding is completed, the limit bolt 29 is removed, and then the slide bar 30 is pulled until the first stop 31 is away from the positioning rod 15. The locking block 34 is pulled out, and the locking block 34 is rotated in the opposite direction to drive the movable rod 18 to rotate, which drives the threaded sleeve 20 to move back, thereby driving the transmission plate 22 to pull the adjusting plate 21 to rotate, driving the support block 23 to retract, thereby releasing the limit on the winding drum 25, which facilitates the unloading of the winding drum 25.

[0022] Working principle: The take-up drum 25 is fitted onto the positioning rod 15. The second drive motor 24 is started, driving the bidirectional screw 26 to rotate, thereby causing a pair of limiting plates 28 to move towards each other, achieving the limiting of the two ends of the take-up drum 25 by a pair of first stops 31, and simultaneously achieving the centering of the take-up drum 25. Rotating the movable rod 18 drives the threaded sleeve 20 to move, the threaded sleeve 20 pushes the transmission plate 22 to move, the transmission plate 22 pushes the adjusting plate 21 to rotate, thereby lifting the support block 23. Several support blocks 23 abut against the inner ring of the take-up drum 25, achieving the limiting of take-up drums 25 of different sizes. After adjusting the movable rod 18, press the locking block 34 until the locking block 34 engages with the locking groove 33, thereby achieving the limiting of the movable rod 18 and the positioning rod 15. The retractable mesh heating pad is mounted on the directional roller 12, then pulled out from between a pair of pressure rollers 11, and rotates around the take-up drum 25. The first drive motor 5 is started to drive the drive wheel 6 to rotate, which in turn drives the driven wheel 7 to rotate through the transmission sprocket 8, thereby driving the take-up structure 2 to rotate and the take-up drum 25 to rotate, thus achieving take-up. After take-up is completed, the limit bolt 29 is removed, and then the slide bar 30 is pulled until the first stop 31 is away from the positioning rod 15. The locking block 34 is pulled out, and the locking block 34 is rotated in the opposite direction to drive the movable rod 18 to rotate, which drives the threaded sleeve 20 to move back, thereby driving the transmission plate 22 to pull the adjusting plate 21 to rotate, which drives the support block 23 to retract, thereby releasing the limit on the take-up drum 25 and facilitating the unloading of the take-up drum 25.
