[0026] Compared with the prior art, a slidable material guide cylinder 41 is arranged between the discharge pipe 21 and the feed pipe 12, wherein the material guide cylinder 41 slides relative to the bracket 3 under the drive of the driving member 42. When the material guide cylinder 41 extends relative to the feed pipe 12 and is connected with the material guide cylinder 41, it is used to guide the material into the feed pipe 12 to prevent the material from leaking out.

Compared with the prior art, a slidable material guide cylinder 41 is arranged between the discharge pipe 21 and the feed pipe 12, wherein the material guide cylinder 41 slides relative to the bracket 3 under the drive of the driving member 42.

When the material guide cylinder 41 retracts relative to the feed pipe 12, it is convenient for the user to adjust the position of the mixing cylinder 2 so that the discharge pipe 21 of the mixing cylinder 2 is aligned with the feed pipe 12 of the extruder 1.
[0052] When in use, the user first pushes the mixing barrel 2 to the top of the feed pipe 12 of the extruder 1, and sets the discharge pipe 21 relative to the feed pipe 12, and then uses the extension of the driving member 42 to make the abutment block 44 and the guide barrel 41 slide relative to the bracket 3, and then the abutment block 44 slides and abuts against the discharge pipe 21, and finally the discharge can begin.
[0053] Furthermore, after unloading is completed, the user utilizes the recovery of the driving member 42 to drive the abutment block 44 to separate from the discharge pipe 21, and finally overlap with the bracket 3, where the elastic part 45 abuts against the bracket 3 for buffering.
