[0029] See also Figure 3 The adjusting assembly 11 includes an adjusting rod 111 and a screw rod 114. The lower end of the adjusting rod 111 extends through the bottom of the driving shaft 12, and the upper end of the adjusting rod 111 is fixedly connected to the first bevel gear 112. The adjusting rod 111 is rotatably connected to the inner cavity of the driving shaft 12. The upper end of the side wall of the driving shaft 12 is fixedly connected to a limiting sleeve 115. The screw rod 114 passes through the limiting sleeve 115 and extends into the inner cavity of the driving shaft 12 and is fixedly connected to the second bevel gear 113. The second bevel gear 113 is meshed with the first bevel gear 112. The end of the screw rod 114 facing away from the second bevel gear 113 is threadedly connected with a screw sleeve 116.

The limiting sleeve 115 limits the screw sleeve 116 so that the screw sleeve 116 moves along the inner wall of the limiting sleeve 115, thereby regulating the distance between the shift block 117 and the axis of the adjusting rod 111.

[0031] It should be added that the top of the shift block 117 is an arc-shaped convex surface to avoid jamming when the shift block 117 abuts against the lower end surface of the cloth tray 23.

[0032] It should be noted that the threaded sleeve 116 and the limiting sleeve 115 have the same shape, which is a rectangle or other prism shape.

[0033] See also Figure 5 and Figure 6 The feeding disk 23 includes a disk body 233, and a plurality of groups of feeding holes 231 are arranged at intervals on the upper end surface of the disk body 233. A mounting groove 232 is arranged on the side wall of the feeding hole 231.

The feeding plate 234 includes a plate body 2342, and the center end of the plate body 2342 is hingedly connected to the side wall corresponding to the position of the feeding hole 231, one side of the plate body 2342 extends into the mounting groove 232 and is fixedly connected with a plurality of groups of elastic components 2341 at intervals, and a plurality of groups of elastic components 2341 are fixedly connected to the side wall of the mounting groove 232 away from the plate body 2342, and a wedge-shaped strip 2343 is fixedly connected to the lower end surface of the plate body 2342 away from the elastic component 2341, and the height of the wedge-shaped strip 2343 gradually increases from the center of the circle to the circumference.

[0034] It should be added that the length of the elastic component 2341 gradually increases from the center to the circumference, that is, when the elastic component 2341 is not subjected to external force, the plate body 2342 completely closes the feed hole 231 .

[0035] It should also be added that the upper end surfaces of the material distribution hole plate 22 and the disk body 233 are conical.

[0036] Principle: The raw material is put into the mixing box 13 through the feeding end, and then the carrier is put into the storage box 21 through the feeding port. The driving component 15 drives the driving shaft 12 to drive the mixing frame 14 to stir the raw material. At the same time, the rotating shifting block 117 abuts against the wedge-shaped shifting bar 2343 at intervals, so that the plate 2342 compresses the elastic component 2341 to move into the installation groove 232, so that the discharge hole 231 is partially opened. The carrier in the storage box 21 passes through the gap opened by the discharge hole 231 through the distribution hole plate 22 and is evenly distributed to the mixing box 13 to mix with the catalyst raw material. By rotating the adjusting rod 111, the first bevel gear 112 is meshed with the second bevel gear 113 to drive the screw 114 to rotate, and the screw sleeve 116 is controlled to slide in the screw 114, so as to adjust the distance between the shift block 117 and the axis of the adjusting rod 111. As the distance between the two increases, the time that the shift block 117 abuts against the wedge-shaped shift bar 2343 increases, thereby expanding the angle of the gap opened by the discharge hole 231 and increasing the single feeding amount of the carrier. On the contrary, the abutment time is reduced and the feeding amount is reduced, so that the feeding amount can be adjusted according to demand, and the evenly mixed catalyst is extruded through the extrusion port.
