The positioning hole includes a first positioning hole 5, and an oval groove 7 coaxial with the first positioning hole 5 is arranged on the outer side wall of the shell 1. The side of the positioning seat 9 towards the shell 1 is fixedly provided with a hollow positioning block 8, and the positioning block 8 is located in the oval groove 7. The positioning block 8 can drive the crushing roller 11 to move horizontally on the oval groove 7, and the oval groove 7 is provided with a stabilizing piece for preventing the crushing roller 11 from shaking. The positioning hole further includes a second positioning hole 4, and a circular groove 6 coaxial with the second positioning hole 4 is arranged on the outer side wall of the shell 1, and a hollow positioning block 8 is also arranged in the circular groove 6. Specifically, the side of the positioning seat 9 away from the positioning block 8 is detachably provided with a bearing gland 10, and the crushing roller 11 is rotatably connected with the positioning seat 9 through the bearing gland 10.

[0028] In the utility model, when the crushing roller 11 is worn and the gap between two adjacent crushing rollers 11 becomes larger, the crushing roller 11 on the second positioning hole 4 does not move, according to the gap required between the adjacent crushing rollers 11 in the crushing process, the positioning block 8 moves horizontally on the respective oval groove 7, drives the crushing roller 11 on the positioning block 8 to move, thereby reducing the gap between the adjacent crushing rollers 11, avoiding affecting the material crushing effect, and improving the service life of the crushing roller. The stability of the crushing roller 11 is improved by the stabilizing piece, and the gap between the positioning block 8 and the oval groove 7 is avoided to cause the crushing roller 11 to shake, thereby affecting the material crushing. The utility model can change the size of the gap between two adjacent crushing rollers 11, and is suitable for material crushing with different crushing effect requirements.

[0029] Specifically, the positioning block 8 is cylindrical. The diameter of the positioning block 8 is smaller than the minor axis of the oval groove 7, and the positioning block 8 is matched with the circular groove 6. The stabilizing piece is located in the gap between the positioning block 8 and the oval groove 7, and the stabilizing piece is a crescent washer 12. The size of the crescent washer 12 is equivalent to the gap between the positioning block 8 and the oval groove 7. In the utility model, after the position of the positioning block 8 on the oval groove 7 is determined, according to the size of the gap between the positioning block 8 and the oval groove 7, the crescent washer 12 with appropriate thickness is selected, and the stability of the positioning block 8 and the crushing roller 11 in the crushing process is improved.

[0030] The outer wall of the housing 1 is provided with several sets of first positioning members, which are located above and below the circular groove 6 and the elliptical groove 7, respectively. Each first positioning member includes two first screw holes 13. The upper and lower ends of the positioning seat 9 are each provided with a set of second positioning members, which include two through slots 14 and several first bolts 15. The first bolts 15 sequentially pass through the through slots 14 and the first screw holes 13 to fix the positioning seat 9 to the housing 1. In this invention, the positioning seat 9 is fixed to the housing 1 by the first bolts 15, preventing the positioning seat 9 from shaking up and down.

[0031] The through slots 14 above and below the circular groove 6 match the first bolt 15, and the through slots 14 above and below the elliptical groove 7 are clearance-fitted with the first bolt 15. Several adjusting components are fixedly mounted on the housing 1, located above and below the elliptical groove 7. Each adjusting component includes two fixed seats 16 and two second bolts 17, with the two fixed seats 16 located on either side of the positioning seat 9. The fixed seats 16 have second screw holes, the axis of which is perpendicular to the axis of the first screw hole 13. The second bolts 17 can pass through the second screw holes, pushing the positioning block 8 to move horizontally on the elliptical groove 7. This invention, by tightening the second bolts 17, changes the length of the second bolts 17 passing through the fixed seats 16 on both sides of the elliptical groove 7, pushing the positioning block 8 of the positioning seat 9 to move horizontally on the elliptical groove 7, thereby causing the crushing roller 11 to move horizontally, changing the gap between two adjacent crushing rollers 11, and ensuring that the gap between the two adjacent crushing rollers 11 is always within a suitable range. The adjusting components and the crescent-shaped gasket 12 together serve a positioning function, preventing the crushing roller 11 from shaking during operation. The through slots 14 above and below the elliptical groove 7 will not affect the movement of the positioning seat 9.

[0032] The second positioning component has a detachable connecting plate 18 on the side away from the positioning block 8. The connecting plate 18 is horizontally positioned. The connecting plate 18 has two through holes, and the first bolt 15 passes through the through holes and through the through groove 14 in sequence to be threaded into the first screw hole 13. The housing 1 is also equipped with a motor that drives the crushing roller 11 to rotate.

[0033] The inner wall of the housing 1 is provided with two first baffles 19, which are located above two adjacent crushing rollers 11. These first baffles 19 prevent material from entering the gap between the adjacent crushing rollers 11 and the housing 1. A second baffle 20 is provided on the inner wall of the side of the housing 1 away from the two first baffles 19. The second baffle 20 is located below the crushing roller 11 away from the two first baffles 19, and it prevents material from entering the gap between the crushing roller 11 located on the same side and the housing 1. This invention, by providing the first baffles 19 and the second baffle 20, prevents material from entering the small gap between the crushing roller 11 and the housing 1, thus preventing material leakage.

[0034] Detailed operation process

[0035] The alkali fiber is added into the feed inlet 2 of the shell 1, and the alkali fiber is crushed by the crushing roller 11, and the alkali fiber is discharged from the discharge outlet 3 below the shell 1, at this time, the gap between two adjacent crushing rollers 11 is 1mm. When the crushing roller 11 is worn, the gap between two adjacent crushing rollers 11 is greater than 1mm, and the motor is closed. According to the distance that the crushing roller 11 needs to move, the second bolt 17 on one side of the oval groove 7 is loosened, and then the second bolt 17 on the other side of the oval groove 7 is tightened so that the end of the second bolt 17 abuts against the side wall of the corresponding positioning seat 9 and pushes the corresponding positioning seat 9 to be close to the middle positioning seat 9, until the gap between two adjacent crushing rollers 11 becomes 1mm again.

[0036] The first bolt 15 above and below the oval groove 7 is loosened, the gap size between the positioning block 8 and the oval groove 7 is measured, and the corresponding size crescent washer 12 is replaced, and then the first bolt 15 above and below the oval groove 7 is tightened. Start the motor, and the crushing roller 11 crushes the alkali fiber again.
