Description

Technical Field

[0001] This utility model relates to the field of PE double-wall corrugated pipe technology, specifically to a PE double-wall corrugated pipe production device. Background Technology

[0002] PE double-wall corrugated pipe is a type of pipe designed to optimize the cross-section of the pipe while saving raw materials without reducing the ring stiffness of the pipe. Its structural features include a smooth and flat inner wall, a trapezoidal or arc-shaped corrugated rib on the outer wall, and a hollow space between the inner and outer corrugations. This design not only reduces the use of raw materials but also improves the strength and stiffness of the pipe.

[0003] In the production process of PE double-wall corrugated pipes, a crucial step is to feed PE raw materials into an extruder, where they are heated, melted, and extruded to form the initial shape of the pipe. However, a common problem during this raw material feeding process is that PE raw materials tend to adhere to and contaminate the inner wall of the feed hopper. This contamination not only wastes raw materials but also adversely affects subsequent PE double-wall corrugated pipe production, potentially leading to production interruptions or a decline in product quality.

[0004] Therefore, a PE double-wall corrugated pipe production device is proposed. Utility Model Content

[0039] A positioning sleeve 66 is fixedly installed on the inner wall of the movable frame 63, and a positioning rod 67 is fixedly installed on the bottom surface of the movable plate 65. The lower end of the positioning rod 67 is located inside the positioning sleeve 66 and is slidably connected to the inner wall of the positioning sleeve 66. A spring 68 is sleeved on the outer side of the positioning rod 67, and the two ends of the spring 68 are fixedly connected to the movable plate 65 and the positioning sleeve 66.

[0040] Furthermore, in this embodiment, the cylinder 62 drives the positioning seat 61 to move, and the positioning seat 61 drives the molding machine 3 to slide, so that the extruder 2 is connected to the molding machine 3. When the positioning seat 61 moves, it drives the moving frame 63 and the moving plate 65 to move synchronously. When the moving plate 65 moves to the right, since the right end of the moving plate 65 is at an angle, when it approaches the fixed frame 64, under the influence of the fixed frame 64, the moving plate 65 first moves downward, and then under the action of the spring 68, the moving plate 65 returns to its original position, so that the right end of the moving plate 65 is located in the internal connecting groove of the fixed frame 64, thereby completing the fixation of the moving frame 63 and the fixed frame 64.

[0041] Furthermore, in this embodiment, when the positioning seat 61 moves, it not only drives the molding machine 3 to move, but also moves the moving frame 63 and the moving plate 65 simultaneously. During the movement of the moving plate 65 to the right, the angled design at its right end allows it to move downwards first when it approaches the fixed frame 64, and then return to its original position under the action of the spring 68. This ensures the stability and firmness of the connection between the extruder 2 and the molding machine 3.

[0042] In use, PE raw material is fed into the feed hopper 53, and then the first motor 55 is started. The first motor 55 drives the first pulley 56 to rotate, and the first pulley 56 drives the second pulley 57 to rotate via a belt. The second pulley 57 drives the connecting frame 58 and the cleaning frame 59 to rotate synchronously. The brush installed on the cleaning frame 59 cleans the inner wall of the feed hopper 53, scraping off the PE raw material adhering to the inner wall. The PE raw material enters the extruder 2 from the connecting seat 54. The extruder 2 melts the PE raw material and extrudes it into the preliminary shape of a pipe. The second motor 510 is started, and the second motor 510 drives the adjusting roller 511 to rotate. The connecting seat can be adjusted according to the rotation angle of the adjusting roller 511. The size of the discharge path inside 54 is determined by the cylinder 62, which drives the positioning seat 61 to move. The positioning seat 61 drives the molding machine 3 to slide, connecting the extruder 2 and the molding machine 3. When the positioning seat 61 moves, it drives the moving frame 63 and the moving plate 65 to move synchronously. When the moving plate 65 moves to the right, because the right end of the moving plate 65 is at an angle, as it approaches the fixed frame 64, under the influence of the fixed frame 64, the moving plate 65 first moves downward. Then, under the action of the spring 68, the moving plate 65 returns to its original position, so that the right end of the moving plate 65 is located in the internal connecting groove of the fixed frame 64, thereby completing the fixation of the moving frame 63 and the fixed frame 64, further enhancing the firmness of the connection between the extruder 2 and the molding machine 3.
