Detailed Embodiments

[0022] The present utility model will be specifically described below with reference to the accompanying drawings.

[0023] Embodiment: A horizontal double-station stretching machine for corrugated pipe production, as Figures 1 - 4 shown, includes a stretching machine 1. The stretching machine 1 is of a double-station type, that is, the stretching machine 1 is configured with two feeding trays 2 for feeding. The feeding trays 2 are provided with feeding guide rails 3. The side of the feeding trays 2 is provided with through grooves, and fixing plates 4 are fixedly connected at corresponding positions of the through grooves. A lead screw 5 is rotatably connected in the fixing plate 4 and is powered by a servo motor 6. The lead screw 5 is provided with a closed double-thread. Therefore, when the servo motor 6 is started to drive the lead screw 5 to continuously rotate, the lead screw 5 can drive the pushing block 7 to reciprocate. The pushing block 7 is limited to slide in the through groove and is sleeved on the lead screw 5 through a thread.

[0024] As Figure 3 shown, a bottom plate 9 is arranged on the inner bottom surface of the feeding guide rail 3. The bottom plate 9 is provided with top plates 10. A return spring 11 is connected between the top plates 10 and the feeding guide rail 3. A contact block 12 is arranged at the end of the top plate 10. A push rod 8 is fixedly connected to the pushing block 7, and the push rod 8 can contact and push the contact block 12.

[0025] As Figure 2 shown, it further includes a guide roller 13. The guide roller 13 is arranged on the side of the pushing block 7. The arrangement of the guide roller 13 greatly reduces the friction coefficient between the pushing block 7 and the raw material.

[0026] As Figure 2 shown, it further includes a limiting rod 14. The limiting rod 14 is connected to the end of the feeding guide rail 3, and the limiting rod 14 is used to limit the raw material.

[0027] As Figure 2 shown, it further includes a foam pad 15 and a shock pad 16. The foam pad 15 is arranged on the inner side surface of the feeding guide rail 3, and the shock pad 16 is arranged on the surface of the top plate 10.

[0028] Working principle: The raw material for corrugated pipe production enters the stretching machine 1 through the feeding guide rail 3 of the feeding tray 2. The servo motor 6 is started to drive the lead screw 5 to continuously rotate. The lead screw 5 can drive the pushing block 7 to reciprocate. During the movement of the pushing block 7, it can not only push the raw material in the feeding guide rail 3 downward through the protruding part on its side, and at the same time, the push rod 8 at the bottom of the pushing block 7 can regularly push the contact block 12, so that the top plate 10 fluctuates in a wave shape, so as to cooperate with the pushing block 7 to push the raw material to be transported. Since the limiting rod 14 is provided, the raw material will cross the limiting rod 14 and will not move backward after moving to the frontmost top plate 10. Thus, when the pushing block 7 moves backward, it cannot push the raw material back. Therefore, the corrugated pipe raw material is fed by vibration and guiding, avoiding the phenomenon of material jamming.

[0029] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
