DETAILED DESCRIPTION

[0019] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0020] A HDPE double-wall corrugated pipe extrusion device, such as Figure 1-Figure 3 As shown, it includes a placement frame 1, a guide rail 2, a sliding block 3, a cylinder 4, a top block 5, a double-axis motor 6, a screw rod 7 and a connecting frame 8. The left and right upper sides of the placement frame 1 are both equipped with guide rails 2 for sliding guidance. The upper middle side of the upper part of the placement frame 1 is connected to an arc-shaped placement surface. The front and rear parts of the guide rail 2 are both slidably connected to the sliding block 3. The upper middle side of the sliding block 3 is connected to a cylinder 4 for lifting, pushing and extruding. The top block 5 for extruding a double-wall corrugated pipe is connected to the telescopic rod of the cylinder 4. The upper middle side of the lower part of the placement frame 1 is connected to a double-axis motor 6 for driving sliding. The output shaft of the double-axis motor 6 is connected to a screw rod 7. 7 are all threadedly connected with a connecting frame 8, and the left and right parts of the connecting frame 8 are connected to the upper sides of adjacent sliding blocks 3, and also include a stabilizing mechanism 9, which includes a fixed seat 91, a rotating frame 92, a stabilizing wheel 93 and a volute spring 94. Two fixed seats 91 are connected to the front and rear sides of the upper middle part of the placement frame 1, and the fixed seats 91 are rotatably connected with the rotating frames 92. The upper part of the rotating frame 92 is rotatably connected with two stabilizing wheels 93 for stabilizing the extrusion of double-wall corrugated pipes, and the stabilizing wheels 93 are connected with anti-slip surfaces. The lower part of the rotating frame 92 is connected to two volute springs 94 between the adjacent fixed seats 91.

[0021] This device can be used when extruding HDPE double-wall corrugated pipes. It should be noted that the produced double-wall corrugated pipes are first placed on the upper side of the placement rack 1. At this time, the stabilizing wheels 93 are in contact with the upper outer wall of the pipe, and then the double-axis motor 6 is started, so that the output shafts of the double-axis motor 6 drive the adjacent screw rods 7 to rotate. At this time, the screw rods 7 drive the sliders to slide inward along the guide rails 2 through the adjacent connecting racks 8, so that the cylinders 4 drive the adjacent top blocks 5 to move inward and fit between the outer wall of the pipe, and then the four cylinders 4 are started, so that the telescopic rods of the cylinders 4 drive the adjacent top blocks 5 to push upward. The pipe is moved, and the middle part of the pipe pushes the eight stabilizing wheels 93 outward. At the same time, the stabilizing wheels 93 rotate to assist in extruding the outer wall of the pipe, so that the stabilizing wheels 93 drive the adjacent rotating frames 92 to rotate and open outward. At this time, the volute springs 94 are all forced to rotate, and then the top block 5 continuously pushes the pipe upward to be slowly extruded, and then the extruded pipe can be transported using a handling tool. In summary, through the cooperation between the rotating frame 92 and the stabilizing wheels 93, the double-wall corrugated pipe in the extrusion process is assisted and stably supported, thereby avoiding shaking during the extrusion of the double-wall corrugated pipe and improving the stability of the pipe extrusion.

[0022] like Figure 1 and Figure 4 As shown, it also includes a supporting mechanism 10, which includes a servo motor 101, a transmission assembly 102, a fixed frame 103 and a stabilizing plate 104. The servo motor 101 is connected to the upper middle sides of the left and right parts of the placement frame 1, the fixed frame 103 is connected to the upper rear side of the left part of the placement frame 1, and the fixed frame 103 is connected to the upper front side of the right part of the placement frame 1. The fixed frame 103 is rotatably connected with a stabilizing plate 104 for stabilizing the limited placement frame 1, and a plurality of reinforcing plates are connected to the stabilizing plate 104, and the reinforcing plates are in a stable triangular structure with adjacent stabilizing plates 104. The transmission assembly 102 is connected between the output shaft of the servo motor 101 and a part of the stabilizing plate 104, and the transmission assembly 102 includes a pulley and a transmission belt. The output shaft of the servo motor 101 and a part of the stabilizing plate 104 are connected with pulleys, and a transmission belt is wound around the front and rear adjacent pulleys.

[0023] It should be noted that after the placement rack 1 is placed at the designated position for receiving pipes, the two servo motors 101 are started, so that the output shafts of the servo motors 101 drive the stabilizing plates 104 to rotate outward and open through the adjacent transmission components 102, thereby allowing the stabilizing plates 104 to stably limit the placement rack 1. In summary, through the cooperation between the servo motors 101 and the stabilizing plates 104, the placement rack 1 is stably supported, thereby making the placement rack 1 more stable during the process of receiving and extruding the pipes.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
