DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A drawing and winding molding device for producing HDPE kraft pipes includes a support base 1, a U-shaped bracket 2 fixedly connected to the upper end of the support base 1, and an extruder 3 installed at the upper end of the U-shaped bracket 2. This is the prior art. After the extruder 3 melts the HDPE raw material, it extrudes a flat strip through the die on it and adheres it to the surface of the roller mold 13 to form the basic structure of the pipe. By changing the die of the extruder 3, the HDPE raw material can be extruded into a U-shaped strip, which is then wound around the outer layer of the flat strip to complete the production of HDPE kraft pipes.

[0020] The system also includes a moving mechanism, which includes a first motor 4 installed on the right side of the support base 1. The first motor 4 is a motor that can change the direction of rotation. A rectangular slide groove 5 is provided at the upper end of the support base 1. A threaded rod 6 is rotatably connected between the inner walls of the left and right sides of the rectangular slide groove 5. The right side of the threaded rod 6 passes through the inner wall of the right side of the rectangular slide groove 5 (a bearing is provided at the penetration point) and is fixedly connected to the output shaft of the first motor 4. A moving base 7 is threadedly connected to the threaded rod 6. A guide rod 8 is fixedly connected between the inner walls of the left and right sides of the rectangular slide groove 5. The guide rod 8 passes through the moving base 7 and is slidably connected to the moving base 7. By controlling the first motor 4 to drive the moving base 7 and the roller mold 13 above it to move to the right, the flat strip can be evenly attached to the surface of the roller mold 13 in conjunction with the extruder 3 and the rotating mechanism to form the basic structure of the pipe. After moving to the right to the bottom, it is then controlled to move to the left, so that the U-shaped strip can be evenly wrapped around the outer layer of the flat strip to complete the production of HDPE kraft pipe.

[0021] The system also includes a rotating mechanism comprising two rectangular connecting plates 9 positioned above the movable base 7. The lower end of the left rectangular connecting plate 9 is fixedly connected to the movable base 7. Rotating shafts 10 are rotatably connected to the opposing sides of both rectangular connecting plates 9. Circular clamping plates 11 are fixedly connected to the other side of each of the two rotating shafts 10. Circular positioning blocks 12 are fixedly connected to the opposing sides of each of the two circular clamping plates 11. A roller mold 13 is fitted between the two circular clamping plates 11 (an anti-slip layer is provided at the fitting area to improve the clamping of the roller mold 13). For stability), both circular positioning blocks 12 are in contact with the inner wall of the roller mold 13. Together with the two circular clamping plates 11, the roller mold 13 can be clamped and limited. The right side of the rectangular connecting plate 9 on the right side is equipped with a second motor 14. The right end of the rotating shaft 10 on the right side passes through the rectangular connecting plate 9 on the right side (a bearing is provided at the passage) and is fixedly connected to the output shaft of the second motor 14. By starting the second motor 14, the circular clamping plate 11 on the right side is rotated, which in turn drives the roller mold 13 to rotate, thus ensuring the uniform winding of the flat strip and the U-shaped strip.

[0022] The upper end of the movable base 7 is fixedly connected to a support block 15. A telescopic rod 16 is installed on the left side of the support block 15. The telescopic rod 16 is a hydraulic telescopic rod. The telescopic end of the telescopic rod 16 is fixedly connected to the rectangular connecting plate 9 on the right side. By controlling the telescopic rod 16 to drive the rectangular connecting plate 9 on the right side to move to the right, the loading, unloading and adaptive replacement of the roller mold 13 can be easily realized to meet the production needs of HDPE kraft pipes of different lengths. Multiple rollers 17 are installed at the lower end of the rectangular connecting plate 9 on the right side.

[0023] In this invention, HDPE raw material is first fed into extruder 3 and melted. Then, the first motor 4 is started to drive the threaded rod 6 to rotate, which drives the movable base 7 to move to the right in the rectangular slide 5, and drives the roller mold 13 to move to the right in sync. At the same time, the second motor 14 is started to drive the circular clamping plate 11 on the right side to rotate, which drives the roller mold 13 to rotate accordingly. When the right side of the roller mold 13 moves to the die head of the extruder 3, the extruder 3 is started to extrude the molten HDPE raw material into a flat strip and evenly wrap it around the surface of the roller mold 13 until the roller mold 13 moves to the right and reaches the bottom, thus forming the basic structure of the pipe. Then, the die head of the extruder 3 is replaced and the first motor 4 is controlled to reverse, driving the roller mold 13 to move to the left. During this process, the extruder 3 extrudes the molten HDPE raw material into a U-shaped strip and evenly wraps it around the outer layer of the flat strip. In this way, the HDPE kraft pipe can be made. The whole production process is relatively convenient, and by controlling the movement and rotation of the roller mold 13, the uniformity of material winding during the production process is ensured.

[0024] After each production cycle is completed, the operator can control the telescopic rod 16 to move the rectangular connecting plate 9 on the right to the right, thereby releasing the restriction on the roller mold 13. This makes it easier for the operator to remove the HDPE kraft pipe formed on it. Then, the roller mold 13 is aligned with the two circular positioning blocks 12 and the rectangular connecting plate 9 on the right is moved to the left to complete the installation, so that the next production cycle can be carried out. Through the above loading and unloading method, the roller mold 13 can be adapted to the production needs of HDPE kraft pipes of different lengths, which greatly reduces the workload of replacement and improves production efficiency.

[0025] It should be noted that the wiring of the extruder 3, the first motor 4, the second motor 14 and the telescopic rod 16 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control, power supply method and wiring arrangement of the extruder 3, the first motor 4, the second motor 14 and the telescopic rod 16 will not be explained in detail.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
