[0021] In the following description, a lot of specific details are set forth in order to give a full understanding of the utility model, but the utility model can also be implemented by other different ways from the description, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0022] As Figures 1-6As shown, the split type adjustable flat grinding machine comprises a casing 1, a cover 2 which is openably arranged on the casing 1, a discharge port 3 arranged at the bottom of the casing 1, a transmission shaft 4 arranged through the casing 1, an end of the transmission shaft 4 located outside the casing 1 being driven to rotate by a motor 5, a movable grinding wheel 6 being fixedly sleeved on the part of the transmission shaft 4 located inside the casing 1, a feeding port being arranged at the middle of the cover 2, a convex mounting cylinder 7 being arranged at the side of the cover 2 away from the casing 1, the opening of the mounting cylinder 7 being communicated with the feeding port, a grinding wheel seat being arranged on the side of the cover 2 facing the casing 1, the grinding wheel seat comprising a mounting disc 8 and a feeding cylinder 9, the feeding cylinder 9 being inserted into the mounting cylinder 7 along the feeding port, the feeding cylinder 9 being arranged with an opening on the side facing the movable grinding wheel 6, the mounting disc 8 being arranged with a stationary grinding wheel 10, the mounting disc 8 being attached to the side of the cover 2 facing the casing 1, an inlet channel 11 being further arranged at the upper end of the mounting cylinder 7, the inlet channel 11 being communicated with the inlet port arranged on the mounting cylinder 7 and the feeding cylinder 9, a rotary knob adjuster 12 being further arranged at the end of the mounting cylinder 7, the rotary knob adjuster 12 being connected with the end of the feeding cylinder 9, a crushing wheel 13 and a material shifter 14 being further arranged at the end of the transmission shaft 4 located inside the casing 1, the material shifter 14 extending into the feeding cylinder 9 and extending to the inlet port, a plurality of positioning convex shafts 15 being arranged on the mounting disc 8 on the side facing the cover 2, a plurality of positioning holes being arranged on the cover 2 for the positioning convex shafts 15 to be inserted, the diameter of the positioning holes being larger than the diameter of the positioning convex shafts 15, a cylinder seat 16 being arranged on the cover 2 at the positions corresponding to the positioning holes, the cylinder seat 16 being on the same side as the mounting cylinder 7, the positioning convex shafts 15 being inserted into the cylinder seat 16, a positioning spring 17 being further arranged in the cylinder seat 16, the positioning spring 17 being sleeved on the positioning convex shaft 15, an adjusting rod being arranged at the end of the cylinder seat 16, the adjusting rod abutting against the side wall on the back of the mounting disc 8 with the end of the positioning spring 17.

[0023] The adjusting rod comprises a positioning screw 18 screwed on the end of the cylinder seat 16, the end of the positioning screw 18 located inside the cylinder seat 16 being arranged with an adjusting baffle 19, the two ends of the positioning spring 17 abutting against the baffle 19 and the mounting disc 8 respectively.

[0024] The part of the positioning screw 18 located outside the cylinder seat 16 is further arranged with a locking nut 20, the locking nut 20 abutting against the end of the cylinder seat 16.

[0025] By rotating the knob adjuster 12, the entire grinding wheel seat can be controlled to adjust the position in the left and right directions on the machine cover 1, so as to adjust the gap between the static grinding wheel 10 and the dynamic grinding wheel 6. The positioning convex shaft 15 on the mounting disc 8 cooperates with the barrel seat 16 on the machine cover 2, which can ensure that the grinding wheel seat and the static grinding wheel 10 above it do not rotate, and ensure the normal adjustment of the position of the static grinding wheel 10. After adjusting the position of the static grinding wheel 10, in order to ensure the stability of the entire grinding wheel seat, the tension of the positioning spring 17 needs to be adjusted. First, loosen the locking nut 20 on the positioning screw 18, rotate the positioning screw 18 to drive the end adjustment flake 19 to move in the barrel seat 16. When the entire grinding wheel seat moves to the side of the dynamic grinding wheel 6, control the adjustment flake 19 to move to the side of the static grinding wheel 10, so that the positioning spring 19 is tightly pressed between the mounting disc 8 and the adjustment flake 19. Finally, tighten the locking nut 20 at the end of the barrel seat 16. Under the action of the triangular positioning of the positioning spring 19, the mounting disc 8 can be fixed to avoid vibration and shaking during work.

[0026] As shown in Figure 6 The material crushing wheel 13 is provided with a plurality of outwardly extending arc-shaped material crushing pieces along the circumference thereof. The material crushing pieces are provided with a material guiding convex rib 21 on the side facing the static grinding wheel 10. The material guiding convex rib 21 is vertically arranged on the surface of the material crushing piece. The material guiding convex rib 21 is used to facilitate the stirring of the material and ensure that the material can be fully ground.

[0027] The convex surface of the material guiding convex rib 21 is a slope structure with an inner high and outer low.

[0028] The machine shell 1 is installed on the rack 22. The rack 22 is provided with a vertical plate 23 on one side of the top thereof. The vertical plate 23 is provided with an axle seat. The transmission shaft 4 is installed on the axle seat at the end outside the machine shell 1. The vertical plate 23 is also provided with mounting screws 24 at the four corner ends thereof. The heads of the mounting screws 24 are located inside the machine shell 1. The rod bodies of the mounting screws 24 pass through the machine shell 1 and the vertical plate 23. The end of the mounting screw 24 passing through the vertical plate 23 is provided with a fastening nut 25. The part of the mounting screw 24 between the machine shell 1 and the vertical plate 23 is provided with adjusting nuts 26 and washers 27. At least two adjusting nuts 26 are provided. One adjusting nut 26 is tightly attached to the outer wall of the machine shell 1. The cooperation between the adjusting nut 26 and the head of the mounting screw 24 located inside the machine shell 1 fixes the entire mounting screw 24 on the machine shell 1 and prevents it from falling off. The leftmost adjusting nut 26 is tightly pressed against the right side of the vertical plate 23.

[0029] The transmission shaft 4 passes through the casing 1 and is not in a connection relationship with the casing 1, and the movable grinding wheel 6, the material shifter 14 and the like are fixed on the transmission shaft 4. According to the grinding requirement, the gap between the static grinding wheel 10 and the movable grinding wheel 6 can be adjusted, that is, the gap size between the vertical plate 23 and the casing 1 is adjusted. When the gap between the vertical plate 23 and the casing 1 becomes smaller, the gap between the static grinding wheel 10 and the movable grinding wheel 6 becomes smaller. Then, the corresponding number of adjusting nuts 26, that is, the gaskets 27, are assembled on the mounting screw 24 between the vertical plate 23 and the casing 1, and the fastening nut 25 is assembled on the end of the mounting screw 24 passing through the vertical plate 23. The fastening nut 25 cooperates with the adjusting nut 26 and the gasket 27, so that the position of the casing 1 can be fixed. During the whole adjusting process, the closer the casing 1 is to the position of the vertical plate 23, the smaller the gap between the static grinding wheel 10 and the movable grinding wheel 6, and vice versa. The farther the casing 1 is from the vertical plate 23, the larger the gap between the static grinding wheel 10 and the movable grinding wheel 6.

[0030] Furthermore, the adjusting nut 26, the gasket 27 and the fastening nut 25 on the mounting screw 24 at different positions are adjusted, so that the angle adjustment of the static grinding wheel 10 can be realized. After the static grinding wheel 10 and the movable grinding wheel 6 are assembled, the gap between the two grinding wheels at different positions may have a small error due to the assembly of the casing and the casing, or the gap between the two grinding wheels may have an error due to uneven wear after long-time work, that is, the gap between the two grinding wheels is large in some places and small in some places. In order to compensate for this error, the mounting screw 24 at the region with a smaller gap can be adjusted, and the fastening nut 25 on the mounting screw 24 is loosened. At this time, the corresponding casing 1 can be released from the restriction, and then the adjusting nut near the vertical plate 23 is twisted to rotate the adjusting nut 26 away from the casing 1. At this time, since the adjusting nut 26 abuts against the side wall of the vertical plate 23, the position of the adjusting nut does not change, and the mounting screw 24 will be slightly displaced to the right. Since the mounting screw 24 is fixed to the casing 1 through the rightmost adjusting nut, the region of the casing 1 corresponding to the mounting screw will also be slightly displaced to the right. Since the casing 1 is connected with the cover, and the casing 1 is not fixedly connected with the transmission shaft 4 and the movable grinding wheel 6, the casing 1 and the cover 2 will change the angle by a certain angle to the right, so that the angle of the static grinding wheel 10 changes, thereby adjusting the gap between the static grinding wheel 10 and the movable grinding wheel 6, avoiding a large error in the gap between the two grinding wheels. Conversely, the leftmost adjusting nut 26 is twisted to the right, so that the whole casing 1 and the cover 2 change the angle to the left, which can also realize the adjusting function.
