[0031] Please see Figures 1 to 4 The composite heating roller device for polyester film stretching roller assembly provided in this embodiment includes: a composite heating device 1, and an adjustment structure 2 at one end of the composite heating device 1.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 6The adjusting structure 2 includes a docking ring 201, which is slidably connected to the composite heating device 1. An outer roller body 202 is fixedly connected to the outer arc surface of the docking ring 201, and the outer roller body 202 is slidably connected to the composite heating device 1. A circular ring 203 is fixedly connected to one end of the composite heating device 1 at the position corresponding to the docking ring 201. Several circular holes are opened on the side of the circular ring 203 near the docking ring 201. Several circular rods 204 are fixedly connected to the side of the docking ring 201 near the circular ring 203, and the circular rods 204 are slidably connected to the inner wall of the circular holes. An installation ring 206 is slidably connected to the end of the composite heating device 1 away from the docking ring 201. The installation ring 206 is slidably connected to the inner wall of the outer roller body 202, and the surface of the installation ring 206... A threaded connection includes a limiting rod 207. The end of the limiting rod 207 near the mating ring 201 is rotatably connected to a limiting ring 208. Two sliding rods 209 are fixedly connected to the side of the limiting ring 208 near the mounting ring 206. The arc surface of the sliding rods 209 is slidably connected to the mounting ring 206. Positioning plates 212 are slidably connected to both sides of the mounting ring 206. A spring 213 is fixedly connected to the side of the positioning plate 212 near the mounting ring 206. The end of the spring 213 away from the positioning plate 212 is fixedly connected to the mounting ring 206. The end of the positioning plate 212 away from the mounting ring 206 is engaged with the outer roller body 202. The composite heating device 1 and the outer roller body 202 can be easily disassembled and assembled, facilitating maintenance of the composite heating device 1 by the user. To improve the efficiency of maintenance work, two handles 205 are fixedly connected to the side of the docking ring 201 away from the mounting ring 206. The handles 205 have a "U" shaped cross-section. The position and angle of the docking ring 201 and the outer roller body 202 can be adjusted by using the handles 205, making it convenient for the user to apply force. The end of the round rod 204 away from the docking ring 201 is arc-shaped, and the other end is cylindrical, which facilitates the round rod 204 to slide into the round hole on the round ring 203. The end of the limiting rod 207 away from the limiting ring 208 is fixedly connected to an auxiliary block 210. An auxiliary rod 211 is slidably connected to the inner wall of the auxiliary block 210. The auxiliary rod 211 is operated to slide into the auxiliary block 210, and the limiting rod 211 and the auxiliary block 210 are used to drive the limiting rod 207. The position lever 207 rotates, facilitating the user's rotation of the limit lever 207. A bellows 214 is fitted onto the surface of the spring 213, with both ends of the bellows 214 fixedly connected to the positioning plate 212 and the mounting ring 206, respectively. The bellows 214 protects the spring 213, extending its service life. A pull rod 215 is rotatably connected to the surface of the positioning plate 212.

After moving the positioning plate 212 with the help of the pull rod 215, rotating the pull rod 215 to press against the baffles 216 temporarily positions the positioning plate 212, facilitating user operation.

[0033] The working principle of the composite heating roller device for the polyester film stretching roller assembly provided by this utility model is as follows: By setting the adjustment structure 2, the limiting rod 207 is rotated first. The limiting rod 207 drives the limiting ring 208 to move closer to the mounting ring 206 via the thread. The limiting ring 208 drives the sliding rod 209 to slide along the mounting ring 206. During this process, the limiting ring 208 no longer cooperates with the docking ring 201 to abut against the composite heating device 1. Then, the two positioning plates 212 move closer to each other. During this process, the positioning plates 212 disengage from the outer roller body 202 and slide into the mounting ring 206. Spring 2 13 is in a compressed state. Release the limiting position on the mounting ring 206. At this time, move the mounting ring 206 away from the docking ring 201 along the inner wall of the outer roller body 202 of the composite heating device 1. Continue moving the mounting ring 206 to detach it from the composite heating device 1. Then, operate the docking ring 201 and the outer roller body 202 to move away from the composite heating device 1. After maintaining the composite heating device 1, similarly, operate the docking ring 201 and the outer roller body 202 to slide onto the composite heating device 1, and move the round rod 204 on the docking ring 201 into the round hole on the ring 203. Then operate the mounting ring 206... 06. Slide the other end of the composite heating device 1 and the outer roller body 202, so that the two positioning plates 212 are engaged with the outer roller body 202. Rotate the limiting rod 207 in the opposite direction. The limiting rod 207 drives the limiting ring 208 to move closer to the docking ring 201 through the thread. The limiting ring 208 cooperates with the docking ring 201 to abut against both ends of the composite heating device, thereby making the outer roller body 202 stably fixed on the composite heating device 1. The position and angle of the docking ring 201 and the outer roller body 202 can be adjusted by the handle 205 to facilitate the user's leverage. The end of the round rod 204 away from the docking ring 201 is cylindrical. The round rod 204 is slid into the round hole on the ring 203. The operating auxiliary rod 211 slides into the auxiliary block 210. With the help of the auxiliary rod 211 and the auxiliary block 210, the limiting rod 207 is rotated, which makes it convenient for the user to rotate the limiting rod 207. The bellows 214 protects the spring 213 and extends the service life of the spring 213. The operating pull rod 215 moves the positioning plate 212, which makes it convenient for the user to move the pull rod 215. After moving the positioning plate 212 with the help of the pull rod 215, the pull rod 215 is rotated to abut against the baffle 216 to temporarily position the positioning plate 212, which is convenient for the user to operate.
