[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example: Refer to Figure 1-4 A clay extruder includes a base plate 1, an extrusion cylinder 2 mounted on the base plate 1, the end of the extrusion cylinder 2 being open, a support rod 5 fixedly mounted on the top of the base plate 1, a rotating disk 7 mounted on one side of the support rod 5 via a rotating positioning assembly, multiple end disks 8 fixedly mounted on one side of the rotating disk 7, a discharge cylinder 9 mounted on the end disk 8, the end disks 8 being located on one side of the extrusion cylinder 2, one end disk 8 being located on one side of the extrusion cylinder 2, an inlet 3 mounted on the extrusion cylinder 2, and a screw extrusion motor 4 mounted on one side of the extrusion cylinder 2. When using the clay extruder, the clay raw material is added through the inlet 3, and after the screw extrusion motor 4 is driven to run, it drives the screw extrusion rod inside the extrusion cylinder 2 to rotate, thereby extruding the raw material from the discharge cylinder 9. A sealing positioning assembly is provided between the extrusion cylinder 2 and the end disks 8.

[0022] Specifically, the rotary positioning assembly includes an anti-detachment rotary shaft 6 fixedly installed on the side of the support rod 5, a rotary disk 7 rotatably sleeved on the anti-detachment rotary shaft 6, two positioning posts 16 movably installed on the support rod 5, and multiple positioning holes 19 opened on one side of the rotary disk 7. One end of each of the two positioning posts 16 extends into the corresponding two positioning holes 19, and an end plate 17 is fixedly installed on one end of each of the two positioning posts 16. A return spring 18 is fixedly installed between the end plate 17 and the support rod 5. During use, when it is necessary to extrude different diameter types of clay, it is necessary to replace the end disk 8 and pull the end plate 17 to return it to its original position. When the spring 18 is stretched, one end of the positioning post 16 disengages from the positioning hole 19. Then, the end plate 8 is rotated to select a suitable end plate 8 at the end of the extrusion cylinder 2. After selection, the end plate 17 is released, and under the elastic force of the return spring 18, the positioning post 16 is locked in the corresponding positioning hole 19. In this scheme, there are four end plates 8 and four positioning holes 19, arranged in a circumferential array. The number of end plates 8 can be set according to requirements, but the number should be kept even. Different types of end plates 8 can be quickly replaced by rotation to achieve different diameters of extruded clay.

[0023] Specifically, the sealing and positioning assembly includes a movable groove 11 on one side of the extrusion cylinder 2. The movable groove 11 is annular in structure. A movable positioning ring 12 is movably installed in the movable groove 11. An annular positioning groove 10 is provided on one side of the end plate 8. The movable positioning ring 12 is adapted to the annular positioning groove 10. Multiple compression springs 13 are fixedly installed between the inner wall of the movable groove 11 and the movable positioning ring 12. A side slot 14 is provided on the side of the extrusion cylinder 2. The side slot 14 is connected to the movable groove 11. An adjusting block 15 is fixedly installed on the side of the movable positioning ring 12. One side of the adjusting block 15 extends outside the side slot 14. When the adjusting block 15 is released, under the pushing action of the compression spring 13, the end of the movable positioning ring 12 is moved into the annular positioning groove 10, thereby realizing the positioning connection between the end plate 8 and the extrusion cylinder 2 again. At the same time, the movable positioning ring 12 can realize the connection and sealing between the end plate 8 and the extrusion cylinder 2.

[0024] In use: When using the clay extruder, the raw material is extruded from the discharge cylinder 9 to produce clay. During use, when it is necessary to extrude clay of different diameters, different end discs 8 need to be replaced. The end disc 8 can be rotated by disengaging one end of the positioning column 16 from the positioning hole 19. Select the appropriate end disc 8 at the end position of the extrusion cylinder 2. Different types of end discs 8 can be quickly replaced by rotating to achieve different diameters of extruded clay. Loosen the adjusting block 15, and under the pushing action of the compression spring 13, drive the end of the moving positioning ring 12 to move into the annular positioning groove 10, thereby realizing the positioning connection between the end disc 8 and the extrusion cylinder 2 again. At the same time, the moving positioning ring 12 can realize the connection and sealing between the end disc 8 and the extrusion cylinder 2, which is convenient to use.
