[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Figure 1-Figure 3 One embodiment of the utility model is a co-extruder connector, which includes a host connecting block 1 connected to the host and a co-extruder connecting nozzle 2 connected to the co-extruder. The co-extruder connecting nozzle 2 is rotatably connected to the host connecting block 1. Through the connection between the co-extruder connecting nozzle 2 and the host connecting block 1, when the angle of the co-extruder changes or the position of the fuselage is adjusted, the connection with the host can still be maintained, so that the co-extruder can always transport materials to the host.

[0023] The specific problem solved by this embodiment is that the horizontal or vertical position offset between the main machine and the co-extruder will cause the problem of material overflow. In this utility model, a connecting plate 23 is installed between the bending end nozzle 21 and the connecting ball head 24, and the maximum diameter of the inner groove 27 opened on the connecting plate 23 is smaller than the diameter of the connecting ball head 24. On the one hand, when the connecting ball head 24 rotates, the risk of overflow is eliminated, and the stability of the connection with the main machine when the angle of the co-extruder changes is enhanced. On the other hand, the length of the connecting sleeve 26 connected to the connecting ball head 24 and the co-extruder is reduced, thereby reducing production costs. At the same time, the bending end nozzle 21 is connected to the diffusion sleeve 15, that is, the output direction of the raw material in the bending end nozzle 21 is vertical output. The effect of gravity is used to accelerate the speed of the material flowing to the diffusion sleeve 15, that is, the transfer efficiency of the material from the co-extruder to the main machine is improved.

[0024] In this embodiment, the main engine connecting block 1 includes a bushing 11 and a material transfer channel 12 opened in the bushing 11, and a blocking block 13 extending into the material transfer channel is installed on the inner wall of the bushing 11. The blocking block 13 is installed at the upper end of the symmetrical midline of the bushing 11, and a through groove 14 connected to the material transfer channel is opened on one end of the blocking block 13. The through groove 14 and the inner wall of the bushing 11 structure form a discharge cavity, and a diffusion sleeve 15 is installed in the cavity for transitioning materials to the material transfer channel and guiding the flow, and one end of the diffusion sleeve 15 is connected to the co-extruder connecting nozzle 2.

[0025] In this embodiment, the co-extruder connection nozzle 2 includes a bent end nozzle 21 extending inside the bushing 11 and connected to the diffusion sleeve 15. A second material passing channel 22 is provided inside the bent end nozzle 21. A connecting plate 23 is installed at one end of the bent end nozzle 21 away from the diffusion sleeve 15.

[0026] A connecting ball head 24 is sleeved on a partial structure of the connecting plate 23. In the present embodiment, a wrapping distance of the connecting plate 23 on the connecting ball head 24 is greater than a radius of the connecting ball head 24, i.e., the connecting ball head 24 is restricted from being detached from the wrapping of the connecting plate 23. An inner groove 27 is provided in the connecting ball head 24 to form a feeding channel three 25 connected to the bending end nozzle 21. An inner groove 27 with a gradually decreasing diameter is provided in the connecting plate 23. The inner groove 27 is connected to both the feeding channel two 22 and the feeding channel three 25. The diameter of the feeding channel two 22 is greater than the diameter of the feeding channel three 25. The diameter of the inner groove 27 on the end surface where the connecting plate 23 is connected to the feeding channel three 25 is the maximum value, and the maximum diameter of the inner groove 27 is less than the diameter of the connecting ball head 24.

[0027] A connecting sleeve 26 extending toward the co-extruder and connected to the co-extruder is installed at the end of the connecting ball head 24 away from the connecting plate 23, and a through groove 17 with a diameter smaller than the diameter of the connecting ball head 24 is opened at a position on the bushing 11 that matches the connecting ball head 24, thereby restraining the connecting ball head 24 in the bushing 11, and based on the fact that there is no connection between the bushing 11 and the connecting ball head 24, the connecting ball head 24 can rotate in the same direction driven by the connecting sleeve 26, and, under the restriction of the opening diameter of the connecting plate 23, the material transfer channel three 25 is always connected to the inner groove 27 opened on the connecting plate 23, that is, when the co-extruder changes its angle or adjusts the position of the fuselage, it can still maintain connection with the main machine, so that the co-extruder can always convey materials to the main machine.

[0028] In this embodiment, the port diameter of the diffusion sleeve 15 is larger than the size of the discharge cavity, and an arc-shaped narrow gap 16 is opened on the inner wall of the sleeve 11 to facilitate the flow of materials. The arc-shaped narrow gap 16 is rounded to increase the smoothness of the flow of raw materials.

[0029] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
