Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , 2 As shown in Figures 3, 4, and 5, the present invention provides a technical solution: a three-roll machine, including: a grinding machine main body 1 with a grinding roller set 2 disposed in the middle; a position adjustment assembly is disposed above the grinding machine main body 1, and the position adjustment assembly includes a guide rail 3 fixedly connected to the top of the grinding machine main body 1, and a moving seat 6 is slidably connected to the top of the guide rail 3; a cleaning assembly is disposed in the middle of the moving seat 6, and the cleaning assembly includes a sliding block 9 slidably installed on the outside of the moving seat 6, a driving part for driving the sliding block 9 is located on the outside of the moving seat 6, a lifting rod 19 is disposed at the bottom of the sliding block 9, and an elastic part is provided between the lifting rod 19 and the sliding block 9. The elastic part includes a return spring 13 for attaching the cleaning component installed at the bottom of the lifting rod 19 to the grinding roller set.

[0025] It should be noted that in the present invention, the moving seat 6 is fixed to a specified position on the guide rail 3, and the outside of the sliding block 9 is connected to the corresponding component as needed. When it is necessary to clean the grinding roller set 2, the cleaning component is installed at the bottom of the lifting rod 19, and the cleaning component is brought into contact with and pressed against the roller by adjusting the screw 10 and the elastic part. Then, the cleaning component is driven by the driving part to clean the outside of the roller. When it is necessary to perform reciprocating feeding through the sliding block 9, the funnel 17 is installed and connected to the sliding block 9, and the funnel 17 is driven by the driving part to perform reciprocating feeding above the feeding position.

[0026] Please refer to Figure 1 , 2 As shown in the figure, the grinding roller set 2 is rotatably arranged in the middle of the grinding machine main body 1. The grinding roller set 2 includes a fast roller, a medium roller, and a slow roller. The end of the grinding machine main body 1 is adjustably installed with a flow guiding disc 5.

[0027] It should be noted that the main body 1 of the utility model grinding machine further includes a motor that provides power for the three-roll grinding machine and a distance adjustment structure for adjusting the distance between the rollers. The power of the motor is transmitted to the speed reducer, and the speed reducer converts the high-speed rotation of the motor into a low-speed rotation suitable for the operation of the rollers through the internal gear transmission mechanism and increases the torque. The output shaft of the speed reducer is connected to the medium-speed roller through a coupling. The coupling plays the role of transmitting power and compensating for the relative displacement between the two shafts to ensure stable power transmission. In the three-roll grinding machine, the speed ratio gear is used to adjust the speed ratio between the three rollers. The medium-speed roller is connected to the fast roller and the slow roller through the speed ratio gear to achieve a speed ratio relationship of 1:3:9. The differential speed setting enables the material to be subjected to different levels of shear force and friction between the rollers, thereby achieving fine grinding and uniform dispersion of the material particles. The discharged material is collected into a designated container through the guide plate 5.

[0028] Please refer to Figure 1 、 2 As shown in FIGS. 3, a positioning screw 4 is threadedly connected to the end of the moving seat 6 for fixing the moving seat 6 to the outside of the guide rail 3.

[0029] It should be noted that the guide rail 3 of the utility model is connected to the moving seat 6 through a sliding seat. When it is necessary to clean the grinding roller set 2 or add materials to the top of the grinding roller set 2, the moving seat 6 is slid to a designated position, and the guide rail 3 is fixed to the designated position by the positioning screw 4 passing through the moving seat 6 and pressing against the guide rail 3, facilitating the designated operation.

[0030] Please refer to Figure 4 、 5 As shown in FIGS., the driving part includes a transmission belt assembly 8 rotatably arranged on one side of the moving seat 6. A driving motor 7 for driving the transmission belt assembly 8 is fixedly connected to the outside of the moving seat 6. An adjusting screw 10 is threadedly connected to the middle of the sliding block 9, and the bottom of the adjusting screw 10 is rotatably connected to a top plate 11.

[0031] It should be noted that the transmission belt assembly of the utility model includes two belt pulleys rotatably installed on the outside of the moving seat 6 and a transmission belt sleeved on the outside of the two belt pulleys for driving the two belt pulleys. The output end of the driving motor 7 is fixedly connected to one of the belt pulleys, so as to drive the sliding block 9 to slide on the outside of the moving seat 6 through the transmission belt. Cooperating with the travel switch, the outside of the grinding roller set 2 can be wiped and cleaned, and corresponding feeding operations can be carried out in cooperation with the funnel 17.

[0032] Please refer to Figure 3 、 4As shown in FIGS. 5, the elastic part further includes two limiting rods 14 fixedly connected to the bottom of the top plate 11. The outer side of the limiting rod 14 is slidably connected with a bottom plate 12. A return spring 13 is sleeved on the outer side of the limiting rod 14 and at both the top and bottom of the bottom plate 12. The lifting rod 19 is fixedly connected to the bottom of the bottom plate 12, and a cleaning block 18 for fixing the cleaning cloth is fixedly connected to the bottom of the lifting rod 19. A limiting groove 15 for slidably connecting with the lifting rod 19 is formed in the middle of the moving seat 6.

[0033] It should be noted that when cleaning the three rollers of the grinding roller set 2 of the present utility model, the moving seat 6 is moved above the corresponding roller, and a cleaning cloth, towel or the like is wrapped around the outside of the cleaning block 18 and then fixed. Then, the adjusting screw 10 is rotated, and the top plate 11 is driven to move downward by the adjusting screw 10. The top plate 11 drives the lifting rod 19 to move downward along the limiting groove 15, so that the cleaning block 18 is in pressing contact with the roller. The return spring 13 presses the bottom plate 12, and thus presses the lifting rod 19 through the bottom plate 12. The rotation of the grinding roller set 2 is controlled by the control system of the grinding machine main body 1, and the roller is cleaned by the friction wiping between the cleaning block 18 and the roller, so as to avoid manual wiping.

[0034] Please refer to Figure 1 、 2 As shown in FIGS. 3, a connecting slide plate 16 is slidably connected to one side of the moving seat 6. The connecting slide plate 16 is fixedly connected to the sliding block 9, and a funnel 17 is detachably installed on one side of the connecting slide plate 16.

[0035] It should be noted that the funnel 17 of the present utility model is a storage hopper, and a material discharging port is provided at the bottom of the funnel 17. After the moving seat 6 is moved to the feeding position, it is fixed by the positioning screw 4. The funnel 17 is installed on the outside of the connecting slide plate 16, and the funnel 17 is driven to reciprocate by the sliding block 9 and the connecting slide plate 16. When the material in the funnel 17 has a lower concentration, the flow rate is controlled by adjusting the size of the discharging port. When the material in the funnel 17 has a higher concentration, a pressing plate is arranged inside the funnel 17, and the pressing plate is driven by a cylinder installed on the side of the funnel 17 to slowly press the material downward, and reciprocating feeding is realized in cooperation with the sliding block 9.
