The pipes 40 are arranged in a row along the groove width direction of the material distribution groove 25 and are assembled on the clamping frame. The clamping frame is movably installed along the groove width direction of the material distribution groove 25. By moving the clamping frame, the upper pipe orifices of different pipes 40 can be adjusted to be arranged corresponding to the groove opening of the material distribution groove 25. The groove width of the material distribution groove 25 gradually decreases from top to bottom along the height of the material distribution groove 25.

[0023] The material distribution unit 20 includes a material distribution support. The material distribution support is provided with first and second suspension arms and first and second support rods. The first suspension arm 23 is arranged at intervals along the width direction of the material distribution groove 25.

The bottom of the material distribution groove 25 at the end with a larger height is rotationally assembled with the first support rod 21. The bottom of the material distribution groove 25 at the end with a smaller height is placed on the second support rod 22. Since different component resin raw materials and different sizes of the pipe 40 have inconsistent requirements for the inclination angle of the material distribution groove 25, therefore, it is necessary to adjust the angle of the material distribution groove 25. Through the implementation of the above solution, it can effectively meet the adjustment requirements of different inclination angles of the material distribution groove 25.

[0024] More specifically, the material distribution trough 25 is arranged at intervals along the trough width direction of the material distribution trough 25.

The first direction is a horizontal direction perpendicular to the trough width direction of the material distribution trough 25. The clamping plate 31 is connected to a rotational adjustment mechanism, and the sliding seat 35 is connected to a flat push adjustment mechanism. The rotational adjustment mechanism can be one of a cylinder adjustment assembly, an electric cylinder adjustment assembly, and a lead screw nut adjustment mechanism. The adjustment mechanism can be one of a cylinder adjustment assembly, an electric cylinder adjustment assembly, and a lead screw nut adjustment mechanism. The flat push adjustment mechanism can be one of a cylinder adjustment assembly, an electric cylinder adjustment assembly, and a lead screw nut adjustment mechanism. Each clamping unit 30 can be arranged on the clamping plate 31. The respective clamping units 30 are respectively arranged corresponding to the material distribution trough 25. One clamping unit 30 is respectively provided with a set of first and second positioning members.

[0025] During operation, the pipes 40 are respectively arranged on the clamping plate 31 in an inclined juxtaposed arrangement, such that the upper end openings of the pipes 40 directly abutting against the first and second positioning members are arranged corresponding to the discharging ends of the respective material distribution troughs 25. The material valve is opened to inject the resin raw material into the first pipe 40. When the first pipe 40 is filled with the resin raw material, the clamping frame is adjusted to move a distance equal to the diameter of one pipe 40, so as to adjust and make the second pipe 40 and the material distribution trough 25 arranged corresponding to each other. By operating in this way, until all the arranged pipes 40 are filled with the resin raw material.
