[0027] Specifically, one end of the first linkage rod 206 passes through the feeding box 201 and is fixedly connected to the driven wheel 207. A rotating rod 214 is inserted inside the feeding box 201. A driving wheel 208 is fixedly sleeved on the outer surface of the rotating rod 214.

Several limiting posts are arranged in an array on the feeding rack 202, and the rotating rod 214 is located below the feeding rack 202.

[0028] Furthermore, through the feeding assembly 2, the reduction motor 210 is started to drive the drive wheel 208 to rotate. The drive wheel 208 drives the driven wheel 207 to rotate through the belt 209. The driven wheel 207 drives the first linkage rod 206 to rotate.

[0033] Furthermore, by using the chamfering assembly 4, when the cold insulation tube is transported to the placement slot 301 via the feeding rack 202, the first electric push rod 402 drives the clamping plate 403 to move downwards. The guide rod 408 stabilizes the clamping plate 403 during movement. The second electric push rod 404 pushes the connecting plate 405 closer to both ends of the cold insulation tube.

The driven wheel 207 drives the first linkage rod 206 to rotate, which in turn drives the T-shaped rod 203 to rotate, thereby moving the feeding rack 202 to facilitate the feeding and movement of the cold insulation tube. The rotational connection between the crossbar 213 and the T-shaped rod 203 drives the L-shaped rod 211 to rotate. The rotational connection between the second linkage rod 212 and the T-shaped rod 203 and L-shaped rod 211 makes the movement of the cold insulation tube more stable. The cold insulation tube is conveyed by the feeding rack 202. The cold insulation tube is placed on the placement table 3 and limited by the placement groove 301 to facilitate subsequent processing operations. When the cold insulation tube is transported to the placement groove 301 by the feeding rack 202, the clamping plate 403 is moved downward by the first electric push rod 402. The guide rod 408 stabilizes the clamping plate 403 during movement. The second electric push rod 404 pushes the connecting plate 405 closer to both ends of the cold insulation tube. The drive motor 407 is started to drive the second electric push rod 404 to rotate, thereby driving the connecting plate 405 to rotate. The connecting plate 405 drives the chamfering knife 406 to rotate, thereby cutting and chamfering both ends of the cold insulation tube, improving the practicality of the device.
