[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, the gear 5 is meshed with the first rack 6 and the second rack 7 respectively, one end of the two limit rods 10 is movably connected with one side of the two auxiliary plates 9 respectively, and the two tensioning cylinders 13 are fixedly sleeved with one end of the two tensioning rods 12 respectively. The diameters of the two tensioning cylinders 13 are larger than the diameters of the two tensioning rods 12. The utility model is a TPU braces diaphragm production device. By setting an auxiliary groove 8, a reinforcement rod, a positioning rod 14 and a positioning hole 15, when the first rack 6 and the second rack 7 are meshed with the gear 5, the force will be transmitted to the reinforcement rod, and the reinforcement rod slides inside the auxiliary groove 8, so that the first rack 6 and the second rack 7 can move up and down more firmly.

[0026] Working principle: TPU braces refer to invisible braces. Compared with metal braces, invisible braces are not a simple layer of plastic. The diaphragm of the braces is a special elastic material. Some teeth are usually glued with small raised attachments to assist the movement of teeth and bone nails. There are also some special force-adding structures on the braces diaphragm to assist the movement of teeth. Braces made of different materials have different hardness and different strengths to help teeth move. Usually, the material for making invisible braces is TPU. Multi-layer TPU diaphragms are processed by using a production device by matching the thickness of different layers of materials. The produced diaphragms need to be continuously wound and shaped by the winding roller 2. The surface of the diaphragm first abuts against the bottom surface of the tensioning cylinder 13 on the left, and then is transmitted to the center of the two winding rollers 2, and is rolled and shaped by the two winding rollers 2. Then, the surface of the diaphragm will continue to be transmitted to the bottom surface of the tensioning cylinder 13 on the right, and the TPU braces diaphragm will be repeatedly rolled and tensioned. After starting the servo motor 4, it will drive the gear 5 to rotate synchronously. When the gear 5 rotates clockwise , driving the second rack 7 meshing with it to move downward, and the first rack 6 meshing with it to move upward, and the two tensioning cylinders 13 also rise and fall with the rise and fall of the first rack 6 and the second rack 7. The tensioning cylinder 13 can contact the surface of the TPU braces diaphragm being produced and processed, and continuously tension the surface of the diaphragm. The two tensioning cylinders 13 apply pressure to the surface of the TPU braces diaphragm one up and one down respectively, which improves the tensioning effect of the TPU braces diaphragm and improves the quality of subsequent processing of the TPU braces diaphragm. When the first rack 6 and the second rack 7 are meshed and connected with the gear 5, the force will be transmitted to the reinforcement rod, and the reinforcement rod slides inside the auxiliary groove 8, so that the first rack 6 and the second rack 7 can move up and down more firmly. The limit rod 10 can be inserted and moved inside the auxiliary plate 9. After one end of the positioning rod 14 is embedded in the corresponding positioning hole 15, the two are threadedly rotated to connect, so that the auxiliary plate 9 and the limit rod 10 can be limited and fixed, so the position of the tensioning cylinder 13 on the surface of the TPU braces diaphragm can be adjusted.
