[0022] The extrusion roller 17 can rotate in the cylindrical extrusion cavity 16 to further extrude the material, making the material mixed more fully. Furthermore, as the cylindrical extrusion cavity 16 continues to roll, the material can eventually be extruded from the discharge hole group 19 of the material extrusion component, thereby achieving the purpose of shaping the material after stirring.

[0023] Preferably, the screening box 6 includes a box assembly 21 and a support frame 22, the box assembly 21 is fixedly mounted above the support frame 22 through a buffer spring 23, a screening plate 25 is fixedly arranged in the inner cavity of the box assembly 21 through a dividing strip 24, the screening plate 25 separates the inner cavity of the box assembly 21 from top to bottom, the material dividing member 7 is fixedly mounted at the front end of the box assembly 21, and at least one vibration motor 26 is fixedly mounted at the lower end of the box of the box assembly 21; The box assembly 21 receives the material extruded from the material extrusion component discharge hole group 19, and drives itself to vibrate continuously through the vibration motor 26 to screen the material.

[0026] Preferably, the drum drying feeding module 3 further comprises a drying drum support seat 29, on which the drying drum component 8 is fixedly mounted, and on which a driving motor 30 and a reducer 31 which are in transmission cooperation with the mixing component 9 are also fixedly mounted; The drying drum component 8 includes a drum body 32, a front end plate 33 and a rear end plate 34. The upper end of the drum body 32 has a drum body feed port 35 and a hot air port 36 connected to its inner cavity, and the front end plate 33 has a drum body discharge port 37. The drum body 32 can eventually receive the materials that need to be dried, and because the drum body 32 is horizontally placed, the materials can be better dispersed in the inner cavity of the drum, and the stacking height of the materials will not be too high, making it easier to turn over and mix. Compared with the vertical drum structure, such a structure is obviously more conducive to turning over and drying. At the same time, the height of the drum body 32 is greatly reduced, so it is more convenient to feed and unload the materials. By extending the drum body to the next process of the production line, the drum body 32 can also be used to achieve the purpose of transportation on the production line.

[0027] The mixing component 9 includes a mixing shaft 38, both ends of which are rotatably arranged on the front end plate 33 and the rear end plate 34 respectively and are transmission-connected to the drive motor 30 and the reducer 31. A plurality of mixing rods 39 are evenly arranged on the shaft of the mixing shaft 38 along the circumferential direction from front to back, and a paddle 40 is symmetrically arranged on the upper end of each mixing rod 39.

Combined with the hot air blown in from the hot air outlet 36, the drying purpose can be achieved quickly and effectively. The paddle blades 40 can not only contact more materials to achieve a better stirring effect, but also help the materials flow in the drum body 32 toward the drum body discharge port 37 when discharging.

[0029] Preferably, the material extrusion component 5 also includes an auxiliary extrusion component 41 that cooperates with the extrusion operation base 15 and the extrusion roller 17. The auxiliary extrusion component 41 includes a swing arm frame 42, a column mounting seat 43 and a swing arm motor 44.

The plug 46 can pass through the plug matching hole group 1 47 and finally be inserted into the plug matching hole group 2 48 or the plug matching hole group 3 49. Since the plug matching hole group 2 48 and the plug matching hole group 3 49 are connected, the plug 46 can continuously squeeze the material in the columnar extrusion cavity 16 into one of the hole groups of the plug matching hole group 2 48 and the plug matching hole group 3 49, and flow out from the other hole group. In this way, the effect of stirring the materials will be better. At the same time, the materials extruded through the plug matching hole group 2 48 or the plug matching hole group 3 49 are equivalent to preliminary molding, which is more convenient for the final extrusion molding from the material extrusion component outlet hole group 19.

[0035] The use of the feeding blocks 52 can increase the contact area, firstly improving the working efficiency and drying effect during drying. At the same time, since the top angles of all the feeding blocks 52 are facing the drum body discharge port 37, after the drying is completed, it is only necessary to continue to rotate the mixing shaft 38, and the feeding blocks 52 can be used to drive the material toward the drum body discharge port 37 until it finally flows out, thereby achieving the purpose of transportation.

[0036] Preferably, a plurality of auxiliary mixing strips 53 are evenly arranged on the shaft body of the mixing shaft 38 along the circumferential direction.

[0037] Preferably, a plurality of annular spacing frames 54 are arranged at intervals on the outer periphery of the drum body 32 .

[0038] The outer periphery of the drum body 32 can be provided with a protective outer cylinder by using an annular spacer frame 54, which can not only increase the heat preservation of the drying drum component 8 itself, but also avoid the occurrence of scalding accidents.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
