[0023] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0024] In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0025] like Figure 1-Figure 4 As shown, a clamping device for HDPE pipe production is composed of a clamping assembly 1, a fixed plate 2, a transmission motor 3, a fixed frame 4, a transmission gear 5, a roller 6, a baffle 7, a push plate 8, a push rod motor 9, a back plate 10, a rotating wheel 11, a support frame 12, a threaded rod 13, a connecting rod 14, a coupling 15, a roller 16, and a sleeve 17.

[0026] like Figure 1-Figure 4 As shown, transmission motors 3 are provided at both ends of the fixing frame 4, wherein the transmission motor 3 at one end drives the roller 6 to rotate through the rotating wheel 11, and the other end drives the roller 6 to rotate through the transmission gear 5, and a clamping assembly 1 for clamping the HDPE pipe is provided on the fixing frame 4;

[0027] The clamping assembly 1 includes a fixed plate 2, a push plate 8, a support frame 12, a threaded rod 13, a plurality of connecting rods 14, and a roller 16. The fixed plate 2 is arranged on one side of the fixed frame 4, the push plate 8 is arranged on the other side of the fixed frame 4, the support frame 12 is arranged on the push plate 8 and the fixed plate 2, the roller 16 is fixedly installed on the support frame 12, and the plurality of connecting rods 14 and the threaded rod 13 respectively penetrate the fixed frame 4, the fixed plate 2 and the push plate 8.

[0028] The threaded rod 13 and the plurality of connecting rods 14 facing the inner side of the fixing plate 2 and the push plate 8 are sleeved with rod sleeves 17, and the rod sleeves 17 abut against the inner walls of the fixing plate 2 and the push plate 8. The rod sleeves 17 protect the connecting rods 14 and are connected to the fixing plate 2 and the push plate 8 to facilitate movement toward the center of the fixing frame 4.

[0029] Limiting blocks are arranged outside the fixing plate 2 and the pushing plate 8 and are fixedly connected to a plurality of the connecting rods 14 .

[0030] The threaded rod 13 extending to the outside of the push plate 8 is transmission-connected with the push rod motor 9 .

[0031] The rod sleeve 17 sleeved on the threaded rod 13 is provided with an internal thread, which is adapted to the thread on the threaded rod 13. The thread matching transmission is more stable and reliable.

[0032] A coupling 15 is provided between the push rod motor 9 and the threaded rod 13 to effectively prevent the motor from being damaged due to overload or excessive rotation speed.
