Description

Technical Field

[0001] This utility model relates to the field of PVC pipe production technology, and in particular to a traction device for PVC pipe production. Background Technology

[0002] PVC is mainly composed of polyvinyl chloride. Other components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the middle layer is mainly polyvinyl chloride, and the bottom layer is back coating adhesive. It is a popular and widely used synthetic material in the world today. PVC pipes are extruded and cooled simultaneously on the production line, and the extruded PVC pipes need to be traction and conveyed.

[0003] However, existing traction equipment has poor versatility, is not convenient for traction of PVC pipes of different sizes, and has poor traction effect. Utility Model Content

[0004] This invention provides a traction device for PVC pipe production to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a traction device for PVC pipe production, comprising a base, a limiting mechanism, an auxiliary mechanism, and a traction mechanism. The base has an installation groove, within which several lower auxiliary wheels are equidistantly and rotatably mounted. The limiting mechanism consists of a mounting frame, a limiting frame, and a first electric telescopic rod. Two mounting frames are symmetrically mounted on both sides of the base, and two limiting frames are symmetrically located on both sides of the base, situated inside the mounting frames. Several limiting wheels are equidistantly and rotatably mounted on the limiting frames. The first electric telescopic rod is installed within the mounting frame, with its telescopic end connected to the limiting frame. The tops of the two mounting frames are connected... A first fixed plate is installed at the front side of the base. The auxiliary mechanism is installed on the first fixed plate and consists of a second electric telescopic rod and an upper auxiliary wheel. The second electric telescopic rod is installed through the first fixed plate, and an upper auxiliary wheel is installed in the telescopic end of the first fixed plate. A second fixed plate is installed between the tops of the two mounting brackets at the rear side of the base. The traction mechanism consists of a third electric telescopic rod, a traction wheel, and a motor. The third electric telescopic rod is installed through the second fixed plate, and the traction wheel is installed in the telescopic end of the third electric telescopic rod that passes through the second fixed plate. The motor is connected to the traction wheel.

[0006] Preferably, the lower side of the limiting frame is higher than the top of the machine base.

[0007] Preferably, the limiting frame has guide rods that are slidably connected to the mounting frame on both sides of the first electric telescopic rod.

[0008] Preferably, the upper auxiliary wheel does not contact the limiting frame.

[0009] Preferably, the traction wheel does not contact the limiting frame.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] 1. The first electric telescopic rod drives the two limit frames to move in opposite directions, so that the limit wheels can limit the two sides of PVC pipes of different diameters, ensuring the stability of the PVC pipe traction movement.

[0012] 2. The upper auxiliary wheel can be driven to move up and down by the second electric telescopic rod, which limits the movement of PVC pipes of different diameters from above, ensuring the stability of the PVC pipe traction movement.

[0013] 3. The third electric telescopic mechanism can drive the traction wheel to move up and down, contacting PVC pipes of different diameters from above. The motor then drives the traction wheel to rotate and pull the PVC pipes, facilitating the pulling of PVC pipes of different diameters and ensuring the stability of the pulling process.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-3 In this embodiment, a traction device for PVC pipe production includes a base 1, a limiting mechanism 2, an auxiliary mechanism 3, and a traction mechanism 4. The base 1 has an installation groove 11, and several lower auxiliary wheels 12 are rotatably mounted at equal intervals within the installation groove 11. The limiting mechanism 2 consists of a mounting frame 21, a limiting frame 22, and a first electric telescopic rod 23. Two mounting frames 21 are symmetrically mounted on both sides of the base 1. Two limiting frames 22 are symmetrically located on both sides of the base 1 and are situated inside the mounting frames 21. Several limiting wheels 24 are rotatably mounted at equal intervals within the limiting frames 22. The first electric telescopic rod 23 is installed within the mounting frame 21, and its telescopic end is connected to the limiting frame 22. The tops of the two mounting frames 21 are positioned between the front of the base 1. A first fixed plate 25 is installed on the side. The auxiliary mechanism 3 is installed on the first fixed plate 25 and consists of a second electric telescopic rod 31 and an upper auxiliary wheel 32. The second electric telescopic rod 31 is installed through the first fixed plate 24, and an upper auxiliary wheel 32 is installed in the telescopic end of the first fixed plate 25. A second fixed plate 26 is installed between the tops of the two mounting brackets 21 at the rear side of the base 1. The traction mechanism 4 consists of a third electric telescopic rod 41, a traction wheel 42, and a motor 43. The third electric telescopic rod 41 is installed through the second fixed plate 26, and the traction wheel 42 is installed in the telescopic end of the third electric telescopic rod 41 that passes through the second fixed plate 26. The motor 43 is connected to the traction wheel 42.

[0022] With the above technical solution, the produced PVC pipe is inserted through the front side of the machine base 1 and placed on the lower auxiliary wheel 12. Then, according to the diameter of the PVC pipe, the first electric telescopic rod 23 drives the limiting frame 22, so that the two limiting frames 22 move towards each other inside the mounting frame 21, which facilitates the contact of the two sides of PVC pipes of different diameters. The setting of the limiting wheel 24 can ensure that the PVC pipe can be moved easily while being clamped stably. Then, the third electric telescopic rod 41 drives the traction wheel 42 to move and contact the upper surface of the PVC pipe from above. The second electric telescopic rod 31 drives the upper auxiliary wheel 32 to move and contact the upper surface of the PVC pipe from above, which facilitates the limiting of PVC pipes of different diameters and ensures the stability of movement while limiting. After the limiting is completed, the motor 43 drives the traction wheel 42 to rotate, so that the traction wheel 42 drives the PVC pipe to move, thereby stably completing the traction work.

[0023] Preferably, the lower side of the limiting frame 23 is higher than the top of the base 1.

[0024] With the above technical solution, the limiting frame 23 is higher than the base 1, so that the limiting frame 24 will not abut against the base 1 when it moves towards the opposite side, thereby ensuring the stability of the two sides abutting the limiting frame.

[0025] Preferably, the limiting frame 23 has guide rods 27 on both sides of the first electric telescopic rod 21 that are slidably connected to the mounting frame 21.

[0026] Through the above technical solution, the guide rod 27 can ensure the stability of the movement of the first electric telescopic rod 23 driving the limit frame 22.

[0027] Preferably, the upper auxiliary wheel 32 does not contact the limiting frame 23.

[0028] With the above technical solution, the upper auxiliary wheel 32 does not contact the limiting frame 23, so that the limiting frame 23 will not have any impact when limiting PVC pipes of different diameters, thereby ensuring the stability of the upper auxiliary wheel 32 when limiting from above.

[0029] Preferably, the traction wheel 42 does not contact the limiting frame 23.

[0030] With the above technical solution, the traction wheel 42 does not contact the limiting frame 23, so that the limiting frame 23 will not affect the limiting of PVC pipes of different diameters, thereby ensuring the stability of the traction operation of the traction wheel 42.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
