[0002] The twin-shaft extruder is the core equipment in the preparation of flame-retardant PA6 material for automotive corrugated pipes, and it plays an irreplaceable role in material modification, flame retardant dispersion and performance optimization.

[0003] Because the discharge port size of the discharge connection pipe of the traditional automotive corrugated pipe flame retardant PA6 material preparation mechanism is usually fixed, users need to change the discharge connection pipe when they need to extrude materials of different diameters, which is more troublesome and not conducive to improving the work efficiency of the staff.

[0004] This invention addresses the aforementioned problems by providing a mechanism for preparing flame-retardant PA6 material for automotive corrugated pipes that facilitates orifice adjustment. Utility Model Content

[0005] The main purpose of this invention is to address the problem that the discharge port size of the discharge connection pipe in traditional automotive corrugated pipe flame-retardant PA6 material preparation mechanisms is usually fixed. This results in users having to replace the discharge connection pipe when extruding materials of different diameters, which is cumbersome and detrimental to improving the work efficiency of staff.

[0006] To address the aforementioned issues, this utility model proposes a mechanism for preparing flame-retardant PA material for automotive corrugated pipes, comprising: a material preparation extrusion conveying pipe and an outlet connecting pipe provided at the end of the material preparation extrusion conveying pipe; A connecting fixing post is provided at the end edge of the discharge connecting pipe, and a rotating adjusting disk is provided at the center of the connecting fixing post. The rotating adjusting disk is rotatably connected to the connecting fixing post through a rotating shaft. The rotating adjusting disk has discharge adjusting holes of different sizes on a circular track, and a central toggle knob is provided in the middle of the rotating adjusting disk.

[0007] In one embodiment, the central toggle knob is connected to the connecting fixing post by a thread, and the outer side of the central toggle knob is textured.

[0008] In one embodiment, a material preparation extrusion molding device body is provided at the end of the material preparation extrusion conveying pipe, and a side-connected drive motor is connected to the end of the material preparation extrusion molding device body. The side-connected drive motor is electrically connected to an external power source, and a double helical rod is provided inside the material preparation extrusion conveying pipe.

[0009] In one embodiment, an operation console is provided on the side of the material preparation extrusion molding apparatus, and the operation console is provided with a data display screen and adjustment control buttons.

[0010] In one embodiment, a bottom support foot is provided at the bottom of the material preparation extrusion molding apparatus body, and the bottom support foot is located at the corner of the material preparation extrusion molding apparatus body.

[0011] In one embodiment, a discharge pipe with a discharge hopper is connected to the material preparation extrusion conveying pipe, and the discharge pipe is connected to the material preparation extrusion conveying pipe.

[0012] In one embodiment, a bottom support connecting block is connected to the bottom of the material preparation extrusion conveying pipe, and the upper surface of the bottom support connecting block is in arc-shaped contact with the material preparation extrusion conveying pipe.

[0013] In one embodiment, an outer connecting post is provided on the side of the bottom support connecting block, a central threaded rod is connected in the middle of the outer connecting post, a connecting piston is provided at the end of the central threaded rod, and a rubber adsorption plate is provided on the arc-shaped side of the bottom support connecting block, the rubber adsorption plate being in communication with the space where the connecting piston is located.

[0014] Beneficial effects: 1. In the preparation mechanism of flame-retardant PA6 material for automotive corrugated pipes, a connecting fixing post is provided at the end edge of the discharge connecting pipe, and a rotating adjusting plate is provided at the center of the connecting fixing post. The rotating adjusting plate is rotatably connected to the connecting fixing post via a rotating shaft. The rotating adjusting plate has discharge adjusting holes of different sizes on a circular track. A central toggle knob is provided in the middle of the rotating adjusting plate. Because the discharge hole size of the traditional discharge connecting pipe is usually fixed, users need to change the discharge connecting pipe when extruding materials of different diameters, which is cumbersome and does not improve the work efficiency of the staff. After the improvement of this utility model, by adding a rotating adjusting plate, the user can rotate it to align the discharge adjusting hole of the required diameter with the center of the discharge connecting pipe, and then squeeze and tighten it by using the central toggle knob. After the improvement of this utility model, the user can easily change the discharge hole diameter without changing the parts, thereby effectively improving the work efficiency and the practicality of the preparation mechanism of flame-retardant PA6 material for automotive corrugated pipes.

[0015] 2. In the automotive corrugated pipe flame-retardant PA6 material preparation mechanism, an outer connecting column is provided on the side of the bottom support connecting block. A central threaded rod is connected in the middle of the outer connecting column, and a connecting piston is provided at the end of the central threaded rod. A rubber adsorption plate is provided on the arc-shaped side of the bottom support connecting block. The space where the rubber adsorption plate and the connecting piston are located is connected. Because the material preparation extrusion conveying pipe is usually placed directly on the bottom support connecting block or connected by clamps and screws, direct placement is prone to displacement due to collisions, and the connection method of clamps and screws is relatively cumbersome. After the material preparation extrusion conveying pipe is placed on the bottom support connecting block, the user can pull the connecting piston by rotating the central threaded rod to evacuate the rubber adsorption plate. The evacuation of the rubber adsorption plate will create a negative pressure, adsorbing and placing the material preparation extrusion conveying pipe, which can provide a certain degree of connection stability, thereby effectively improving the practicality of the automotive corrugated pipe flame-retardant PA6 material preparation mechanism.

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.

[0020] To achieve the above-mentioned utility model objectives, such as Figure 1-4 As shown, this utility model provides a material preparation mechanism for flame-retardant PA6 material for automotive corrugated pipes, including: a material preparation extrusion conveying pipe 1 and a discharge connecting pipe 7 provided at the end of the material preparation extrusion conveying pipe 1; A connecting fixing post 16 is provided at the end edge of the discharge connecting pipe 7, and a rotating adjusting plate 13 is provided at the center of the connecting fixing post 16. The rotating adjusting plate 13 is rotatably connected to the connecting fixing post 16 via a rotating shaft. The circular track on the rotating adjusting plate 13 is provided with discharge adjusting holes 14 of different sizes. A central toggle knob 15 is provided in the middle of the rotating adjusting plate 13. Because the discharge hole size of the traditional discharge connecting pipe 7 is usually fixed, users need to replace the discharge connecting pipe 7 when extruding materials of different diameters, which is cumbersome and not conducive to improving the work efficiency of the staff. After the improvement of this utility model, by adding the rotating adjusting plate 13, the user can rotate it to make the discharge adjusting hole 14 of the required diameter correspond to the center position of the discharge connecting pipe 7, and then squeeze and tighten it by using the central toggle knob 15. After the improvement of this utility model, the user can easily change the discharge hole diameter without replacing the parts, thereby effectively improving the work efficiency and the practicality of the preparation mechanism for flame-retardant PA6 material of automotive corrugated pipe.

[0021] like Figure 3As shown, the central toggle knob 15 is connected to the connecting fixing post 16 by a thread. The outer side of the central toggle knob 15 is textured. The central toggle knob 15 can be rotated to press and tighten the rotating adjustment plate to keep it in the designated position. The texture on the outside of the central toggle knob 15 can increase the friction with the user's hand, making it convenient for the user to rotate and adjust.

[0022] like Figure 1 As shown, a material preparation extrusion molding device body 4 is provided at the end of the material preparation extrusion conveying pipe 1. A side-connected drive motor 5 is connected to the end of the material preparation extrusion molding device body 4. The side-connected drive motor 5 is electrically connected to an external power source. A double helical rod 9 is provided inside the material preparation extrusion conveying pipe 1. The double helical rod 9 is driven to rotate by the gearbox in the material preparation extrusion molding device body 4 under the action of the side-connected drive motor 5. The double helical rod 9 can convey the extruded and heated material.

[0023] like Figure 1 As shown, an operation control console 10 is provided on the side of the material preparation extrusion molding device 4. The operation control console 10 is equipped with a data display screen 11 and adjustment control buttons 12. Users can set parameters through the operation control console 10 to control the material preparation extrusion molding device 4.

[0024] like Figure 1 As shown, a bottom support foot 8 is provided at the bottom of the material preparation extrusion molding device body 4. The bottom support foot 8 is located at the corner of the material preparation extrusion molding device body 4. The bottom support foot 8 can support the material preparation extrusion molding device body 4, so that the material preparation extrusion molding device body 4 can be placed stably on the ground.

[0025] like Figure 1 As shown, a feeding pipe 3 with a feeding hopper 2 is connected to the material preparation extrusion conveying pipe 1. The feeding pipe 3 is connected to the material preparation extrusion conveying pipe 1. The feeding hopper 2 can increase the feeding diameter of the feeding pipe 3, thereby allowing the user to feed the material more easily.

[0026] like Figure 4As shown, a bottom support connecting block 6 is connected to the bottom of the material preparation extrusion conveying pipe 1. The upper surface of the bottom support connecting block 6 is in arc-shaped contact with the material preparation extrusion conveying pipe 1. An outer connecting post 17 is provided on the side of the bottom support connecting block 6. A central threaded rod 18 is connected in the middle of the outer connecting post 17. A connecting piston 19 is provided at the end of the central threaded rod 18. A rubber suction plate 20 is provided on the arc-shaped side of the bottom support connecting block 6. The space where the rubber suction plate 20 is located is connected to the space where the connecting piston 19 is located. Because the material preparation extrusion conveying pipe 1 is usually placed directly on the bottom support connecting block 6. Alternatively, it can be connected via clamps or screws, but direct placement can easily lead to positional displacement due to collisions, and the operation of clamps and screws is relatively cumbersome. In this improved version, after the material preparation extrusion conveying tube 1 is placed on the bottom support connecting block 6, the user can rotate the central threaded rod 18 to stretch the connecting piston 19 to evacuate the rubber adsorption plate 20. The evacuation of the rubber adsorption plate 20 will create a negative pressure, which will adsorb and place the material preparation extrusion conveying tube 1, providing a certain degree of connection stability, thereby effectively improving the practicality of the automotive corrugated pipe flame retardant PA6 material preparation mechanism.
