DETAILED DESCRIPTION

[0021] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and examples.It should be explained that the embodiment of the present application and the features in the embodiment can be combined mutually without conflict.

[0022] In the following description, a lot of specific details are set forth in order to facilitate a full understanding of the utility model, but the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific embodiment disclosed in the following disclosure.

[0023] Please refer to Figures 1-4 The utility model provides a technical scheme: a kind of flame retardant polyethylene insulation material extrusion forming device, including support 1, support 1 top side installs first drive motor 2, first drive motor 2 one end is connected extruder 3, support 1 top side installs cutting mechanism 4;

[0024] Cutting mechanism 4 includes rotating plate 41, rotating plate 41 central fixed connection rotating rod 43, rotating rod 43 both ends are rotatably connected support column 42, support column 42 top is fixedly connected fixed rod 44, fixed rod 44 top end outer surface rotatably connects limiting roller 441, rotating plate 41 outer top rotatably connects two movable rods 47, movable rod 47 outer surface rotatably connects swing frame 46, swing frame 46 one end is fixedly connected cutting knife 48, two swing frames 46 inner side are all set up mounting groove 461, rotating plate 41 middle part is set up guide groove 45.

[0025] In the polyethylene processing process, first, the first drive motor 2 drives the extruder 3 to complete the extrusion operation of the polyethylene material, ensuring that the material is uniformly and continuously extruded. When the extrusion operation is completed, the rotating plate 41 starts to work, and the rotating plate 41 drives the two swing frames 46 to move synchronously through the rotating ribbon. During the rotation of the rotating rod 43, the rotating plate 41 not only drives the swing frame 46 to move in a circular motion, but also effectively controls the motion trajectory of the swing frame 46. Each swing frame 46 will approach the limiting roller 441 during movement, and at this time, the reaction force of the limiting roller 441 will force the swing frame 46 to be slightly compressed, thereby causing the swing frame 46 to swing.

[0026] The swing of the swing frame 46 is around the movable rod 47, so that the two swing frames 46 can move relatively under the interaction. When the two swing frames 46 are simultaneously subjected to the force from one limiting roller 441, they will move towards the middle, thereby triggering the cutting knife 48 on one side to perform the cutting operation. In this way, the extruded polyethylene tube or rod is accurately cut into the required length under the joint action of the two cutting knives 48.

[0027] The efficient operation of this cutting system relies on the cooperation of the rotating plate 41 and the rotating rod 43, ensuring precise control of the cutting knife 48. With the coordination of the extrusion speed and the rotation speed of the rotating rod 43, the cutting system can be adjusted in real time, thereby accurately controlling the length of each cut material, avoiding any dimensional error. By synchronizing with the extrusion speed, the system can ensure that each cut polyethylene section maintains a consistent length, thereby providing high consistency and stability for subsequent processing and application.

[0028] As shown in Figure 2 , the second drive motor 6 is installed on one side of the top of the support 1, and the output end of the second drive motor 6 is fixedly connected with the belt transmission assembly 5. When the second drive motor 6 operates, it drives the belt transmission assembly 5 to move, thereby transmitting power to the rotating rod 43.

[0029] As shown in Figure 2 , the support column 42 is fixedly connected with the top of the support 1, and one end of the rotating rod 43 is fixedly connected with the output end of the belt transmission assembly 5. When the belt transmission assembly 5 drives the rotating rod 43 to rotate, it can drive the rotating plate 41 to rotate together.

[0030] As shown in Figure 3 , the rotating plate 41 is fixedly connected with two support frames 411 on the top in a symmetrical manner, and the support frames 411 are fixedly connected with limiting rods 412 at the top ends. When the two swing frames 46 are moving, they will be limited by the limiting rods 412, thereby limiting their movement space.

[0031] As shown in Figure 3As shown, the swing frame 46 is slidably connected to the top of the rotating plate 41, and the swing frame 46 abuts against one end of the limit rod 412. The two swing frames 46 will approach each other, and then drive the cutting knife 48 on one side to perform the cutting operation.

[0032] like Figure 3 As shown, a spring 49 is provided between the two swing frames 46, and both ends of the spring 49 are located inside the mounting groove 461. The two swing frames 46 will begin to close together and squeeze the spring 49 inside. The presence of the mounting groove 461 can prevent the spring 49 from escaping.

[0033] like Figure 4 As shown, two cutting knives 48 are staggered with each other. The extruded polyethylene tube or rod can be cut by the two cutting knives 48.

[0034] The device's usage and operating principle are as follows: During polyethylene production and processing, the first drive motor 2 is activated to drive the extruder 3 to perform the extrusion operation. After the extrusion process is completed, the second drive motor 6 is activated, driving the belt drive assembly 5, which in turn transmits power to the rotating rod 43, causing the rotating rod 43 to drive the rotating plate 41 to rotate synchronously.

[0035] During the rotation of the rotating plate 41, it drives the two swinging frames 46 to perform circular motion. When the swinging frame 46 approaches the limiting roller 441, it will hit the limiting roller 441 and, after being squeezed by the reaction force, begin to swing. The swinging frame 46 rotates around the movable rod 47 as the axis. If the two swinging frames 46 are simultaneously affected by the force of a limiting roller 441, they will move closer to each other, thereby driving the cutting blade 48 on one side to perform the cutting action, thus completing the cutting operation of the extruded polyethylene pipe or rod. As long as the extrusion speed and the rotation speed of the rotating rod 43 are accurately matched, the length of each section of material can be ensured to be consistent after each cut.

[0036] The two swing frames 46 begin to close after being acted upon by the limiting rollers 441, squeezing the springs 49 inside. The mounting grooves 461 effectively prevent the springs 49 from falling off. At the same time, the elasticity of the springs 49 generates a reverse force on the two swing frames 46. Furthermore, the limiting rods 412 limit the swing frames 46 during their movement, thereby limiting their range of motion.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
