[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The present invention provides a roller extrusion granulator. Figure 1-Figure 7 As shown, it includes a granulator 1 and a material box 2: the material box 2 is fixed on the top of the granulator 1, and support frames 4 are fixed on both sides of the bottom of the granulator 1. Squeezing rollers 9 are installed on both sides of the inside of the granulator 1, and cleaning structures 7 are provided on both sides of the bottom of the squeezing rollers 9; a mounting frame 8 is fixed at one end of the granulator 1, and a motor 3 is fixed at the top of the mounting frame 8; a fixing plate 6 is installed at one end of the material box 2, and a vibration structure 5 is provided on the top of the fixing plate 6.

[0025] In a further preferred embodiment of the present invention, Figure 1-Figure 7As shown: the vibration structure 5 includes a guide frame 501, a cam 502, a bevel gear set 503, a connecting shaft 504, a moving block 505, a spring 506 and an impact column 507. The bevel gear set 503 is installed on the outside of the output end of the motor 3, and the top of the bevel gear set 503 is installed with a connecting shaft 504. The cam 502 is fixed to the outside of the top of the connecting shaft 504. The guide frame 501 is fixed to one side of the top of the fixed plate 6. The inside of the guide frame 501 is installed with a moving block 505. The impact column 507 is fixed on one side of the moving block 505. A spring 506 is provided on the outside of the impact column 507. The two ends of the spring 506 are respectively fixed to one side of the moving block 505 and one side inside the guide frame 501. A telescopic structure is formed between the spring 506 and the moving block 505. The moving block 505 is inserted into the inside of the guide frame 501, and a sliding connection is formed between the moving block 505 and the guide frame 501.

[0026] Specifically, when granulating, the granulation raw material is poured into the interior of the material box 2. After the raw material is poured in, the external power supply starts the motor 3. After starting, the motor 3 will drive the squeezing roller 9 to rotate. Through the use of the two sets of squeezing rollers 9, the granulation raw material passes through the middle position of the two sets of squeezing rollers 9. At this time, the two sets of squeezing rollers 9 are set to squeeze the raw material through rotation, and granulate through the grooves on the surface to complete the granulation work. When the motor 3 is started, it will drive the bevel gear set 503 to rotate through the connecting rod. When the bevel gear set 503 rotates, The cam 502 is driven to rotate by the connecting shaft 504. When the cam 502 rotates, it pushes the moving block 505 to move inside the guide frame 501. When the moving block 505 moves, it pushes the impact column 507 to hit the outside of the material box 2, generating vibration to vibrate the raw materials stuck on the inner wall of the material box 2, preventing the waste of raw materials and making it more convenient for manual cleaning. After the impact column 507 hits, it returns to its original position under the action of the spring 506, and then cooperates with the rotation of the cam 502 to perform the next impact, thereby completing the vibration work.

[0027] In a further preferred embodiment of the present invention, Figure 1-Figure 7 As shown: the cleaning structure 7 includes a mounting plate 701, a fixing bolt 702 and bristles 703. The mounting plate 701 is installed on both sides of the bottom end of the granulator 1. The fixing bolts 702 are fixed at both ends of one side of the mounting plate 701. The top of the mounting plate 701 is provided with bristles 703. There are two groups of mounting plates 701. The two groups of mounting plates 701 are symmetrically distributed at the bottom end of the granulator 1. There are several bristles 703, and the several bristles 703 are arranged at equal intervals at the top of the mounting plate 701.

[0028] Specifically, when the extrusion roller 9 rotates during granulation, the mounting plate 701 and the brush 703 cooperate to enable the brush 703 to clean the surface of the extrusion roller 9 to prevent the extruded granules from sticking to the surface of the extrusion roller 9, making it more troublesome to clean. The cleaning work is thus completed, and the granulated raw materials are discharged through the bottom end of the granulator 1, thereby completing the granulation work.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
