Description

Technical Field

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

[0002] In the pipe manufacturing industry, the traction device is a key piece of equipment in the extrusion molding production line, and its performance directly affects the production efficiency and quality of the pipes. The traction device facilitates the transition of the extruded pipes from a high-temperature plastic state to the finished product by stably conveying the pipes, controlling dimensional accuracy, and ensuring surface quality. With the increasing demand for pipes from industries such as construction, municipal engineering, and chemicals, as well as the diversification of pipe specifications and materials, higher requirements are being placed on the functionality, adaptability, and reliability of the traction device.

[0003] Currently, most common pipe traction devices on the market use fixed-gap traction rollers or traction belts. These devices drive the traction components to rotate via a motor, using friction to pull the pipe out of the extruder and transport it to subsequent cooling and cutting processes. Their technical principle is mainly based on mechanical transmission and frictional force transmission, achieving the traction action through a simple gear or belt drive system. The structure is relatively fixed and lacks a flexible adjustment mechanism.

[0004] However, due to the significant differences in pipe diameter and wall thickness requirements across various application scenarios, traditional fixed-spacing traction devices are ill-suited to the production needs of multiple pipe specifications. When producing pipes of different diameters, it is often necessary to replace the entire traction equipment or perform complex manual adjustments, which is not only cumbersome and time-consuming but also increases equipment procurement and maintenance costs, thus hindering production efficiency and the company's economic benefits. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a traction device for pipe production, which aims to improve the problem that traditional traction devices are difficult to adapt to pipes of different diameters.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traction device for pipe production, comprising a workbench, a support frame fixedly connected to the upper surface of the workbench, an auxiliary traction component disposed above the workbench, and an adjustment component disposed on the inner wall of the support frame;

[0007] The adjustment assembly includes a bidirectional lead screw, the outer wall of which is threaded to the inner wall of a support frame. Two movable platforms are threaded to the outer wall of the bidirectional lead screw. A slide rail is fixedly connected to the outer wall of the support frame. Two support rods are fixedly connected to the outer wall of each movable platform. A motor is fixedly connected to the outer wall of one of the support rods. A drive shaft is fixedly connected to the output end of the motor. A traction belt is driven to the outer wall of the drive shaft. A wheel is fixedly connected to one end of the bidirectional lead screw.

[0008] Furthermore, the auxiliary traction assembly includes an auxiliary traction roller 1, both of which are disposed above the worktable. A support plate is fixedly connected to the middle side of the inner wall of the worktable. Two bevel gears are rotatably connected to the upper surface of the support plate. A motor 2 is fixedly connected to the lower surface of the support plate. The output end of the motor 2 is fixedly connected to one end of a bevel gear 1. A connecting shaft 2 is fixedly connected to the upper surface of one bevel gear. A double-headed gear is disposed inside the middle side of the worktable. The tooth ends of both bevel gears are meshed with the tooth ends of the double-headed gear. A connecting shaft 1 is fixedly connected to the upper surface of the other bevel gear.

[0009] Furthermore, one end of the second connecting shaft is fixedly connected to the lower surface, and one end of the first connecting shaft is fixedly connected to the lower surface of the auxiliary traction roller.

[0010] Furthermore, the outer wall of the second motor is located on the lower side of the inside of the workbench, and the second motor is used to drive the bevel gear to rotate.

[0011] Furthermore, the outer wall of the second connecting shaft is rotatably connected to the inner wall of the worktable, and the outer wall of the first connecting shaft is rotatably connected to the inner wall of the worktable.

[0012] Furthermore, the two ends of the drive shaft are positioned between two support rods, and the drive shaft is used to drive the traction belt to move.

[0013] Furthermore, the inner walls of both moving platforms are slidably connected to the outer wall of the slide rail, which is used to guide the movement of the two moving platforms.

[0014] Furthermore, the slide rails are symmetrically arranged on the left and right sides of the bidirectional lead screw.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the rotating wheel drives the bidirectional lead screw to rotate, which drives the moving table to move along the slide rail. The spacing of the traction belt is adjusted to adapt to the pipe material. The motor drives the traction belt through the transmission shaft to realize the traction and transportation of the pipe material. This solves the problem that traditional traction devices are difficult to adapt to pipe materials of different diameters. It effectively improves the versatility and applicability of the device, enabling the same equipment to meet the production needs of multiple specifications of pipe materials and reduce equipment procurement costs.

[0017] 2. In this utility model, after the second motor starts, it is driven by bevel gear and double-headed gear to make the auxiliary traction roller rotate. It works with the traction belt to clamp the pipe, thereby enhancing the overall traction force. This enhances the clamping force and traction force on the pipe, ensuring stable conveying of the pipe during the traction process, reducing deformation and conveying interruption caused by unstable clamping, and improving the efficiency of pipe production and the quality of finished products.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 An embodiment of this utility model is provided: a traction device for pipe production, including a workbench 1, a support frame 2 fixedly connected to the upper surface of the workbench 1, an auxiliary traction component provided above the workbench 1, and an adjustment component provided on the inner wall of the support frame 2.

[0027] The adjustment assembly includes a bidirectional lead screw 7, which converts the rotational motion of the wheel 12 into the linear motion of two moving platforms 8, thereby achieving precise adjustment of the spacing of the traction belt 9. The outer wall of the bidirectional lead screw 7 is threadedly connected to the inner wall of the support frame 2. Two moving platforms 8 are threadedly connected to the outer wall of the bidirectional lead screw 7. When the lead screw rotates, they move in opposite directions or away from each other along the slide rail 11. The slide rail 11 is fixedly connected to the outer wall of the support frame 2. Two support rods 3 are fixedly connected to the outer wall of the moving platform 8. A motor 4 is fixedly connected to the outer wall of one support rod 3. A drive shaft 10 is fixedly connected to the output end of the motor 4. The traction belt 9 is connected to the outer wall of the drive shaft 10 and directly contacts the pipe. Through its own rotation and the friction between it and the pipe, the belt clamps and pulls the pipe. One end of the bidirectional lead screw 7 is fixedly connected to the wheel 12.

[0028] Specifically, when the traction device is needed, the rotating wheel 12 is rotated, which drives the bidirectional lead screw 7 to rotate. The thread on the bidirectional lead screw 7 drives the two moving platforms 8 to move towards or relative to each other along the slide rail 11. The moving platforms 8 drive the support rod 3 and the motor 4 to move synchronously, thereby adjusting the distance between the two traction belts 9. After the adjustment is completed, the motor 4 drives the traction belt 9 to rotate through the transmission shaft 10, thereby realizing the traction and transportation of the pipe.

[0029] Reference Figures 1-5The auxiliary traction assembly includes 5 and auxiliary traction roller 6, located above the worktable 1. It works in conjunction with the traction belt 9 to clamp the pipe. Its rotation further enhances the clamping and traction force on the pipe, ensuring the stability of the pipe during traction. Both 5 and auxiliary traction roller 6 are positioned above the worktable 1. A support plate 14 is fixedly connected to the inner wall of the worktable 1. Two bevel gears 16 are rotatably connected to the upper surface of the support plate 14. Driven by a second motor 15, they rotate and, through meshing with a double-headed gear 17, transmit power and change the transmission direction, driving the other bevel gear 16 to rotate synchronously in the opposite direction, thus achieving power distribution and transmission. A second motor 15 is fixedly connected to the lower surface of the support plate 14. The output end of the second motor 15 is fixedly connected to one end of a bevel gear 16. A connecting shaft 18 is fixedly connected to the upper surface of one bevel gear 16. A double-headed gear 17 is provided on the middle side of the part. The tooth ends of two bevel gears 16 are meshed with the tooth ends of the double-headed gear 17. A connecting shaft 13 is fixedly connected to the upper surface of another bevel gear 16. One end of the connecting shaft 18 is fixedly connected to the lower surface of 5. One end of the connecting shaft 13 is fixedly connected to the lower surface of the auxiliary traction roller 6. The outer wall of the motor 15 is set inside the lower side of the worktable 1. The motor 15 is used to drive the bevel gear 16 to rotate. The outer wall of the connecting shaft 18 is rotatably connected to the inner wall of the worktable 1. The outer wall of the connecting shaft 13 is rotatably connected to the inner wall of the worktable 1. The two ends of the transmission shaft 10 are set between the two support rods 3. The transmission shaft 10 is used to drive the traction belt 9 to move. The inner walls of the two moving platforms 8 are slidably connected to the outer wall of the slide rail 11. The slide rail 11 is used to guide the movement of the two moving platforms 8. The slide rail 11 is symmetrically set on the left and right sides of the bidirectional lead screw 7.

[0030] Specifically, after motor 15 starts, it drives bevel gear 16 to rotate. Bevel gear 16 meshes with double-ended gear 17, driving another bevel gear 16 to rotate synchronously in the opposite direction. The two bevel gears 16 drive auxiliary traction rollers 6 and 5 to rotate through connecting shaft 13 and connecting shaft 2, respectively. Auxiliary traction rollers 6 and 5 cooperate with traction belt 9 to clamp the pipe, providing additional support and traction force during the pipe traction process, and enhancing the overall traction force.

[0031] Working principle: When a traction device for pipe production is needed, the rotating wheel 12 drives the bidirectional screw 7 to rotate. The thread of the bidirectional screw 7 drives two moving tables 8 to move towards or relative to each other along the slide rail 11. The moving tables 8 drive the support rod 3 and the motor 4 to move synchronously, thereby adjusting the distance between the two traction belts 9 to adapt to the width of different pipes. The motor 4 drives the traction belt 9 to rotate through the transmission shaft 10 to realize the traction and transportation of the pipe.

[0032] In addition, after the second motor 15 starts, it drives the bevel gear 16 to rotate. The bevel gear 16 meshes with the double-headed gear 17, which drives the other bevel gear 16 to rotate synchronously in the opposite direction. The two bevel gears 16 drive the auxiliary traction rollers 16 and 5 to rotate through the connecting shaft 13 and the connecting shaft 2 18, respectively. The auxiliary traction rollers 16 and 5 cooperate with the traction belt 9 to clamp the pipe and enhance the traction force.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
