Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: an adjustable roll grinding machine, including a machine body 1, a first servo motor 2 is provided inside the machine body 1, and one end of the output shaft of the first servo motor 2 is connected to a bidirectional screw 3 through a coupling. A first slide rod 4 is provided below the bidirectional screw 3, and a first movable block 5 is inserted through both ends of the bidirectional screw 3 and the first slide rod 4. A fixed rod 6 is provided above the first movable block 5.

[0021] Furthermore, under the action of the first servo motor 2, the fixed rod 6 forms a bidirectional limiting sliding structure with the machine body 1 through the bidirectional screw 3, the first slide rod 4, and the first movable block 5, thereby facilitating the compression and limiting of the roller to be ground by the limiting block 7 under the action of the first servo motor 2.

[0022] The fixing rod 6 is provided with a first fixing block on the opposite side, and the first fixing block is inserted into the limiting block 7. A first bolt 8 is inserted on the first fixing block and the limiting block 7, and a first nut is screwed on the other end of the first bolt 8.

[0023] Furthermore, the limiting block 7 forms a spiral locking structure with the first fixing block, the first bolt 8, and the fixing rod 6, which facilitates the adjustment of the size of the limiting block 7 according to the size of the required processing roll.

[0024] The machine body 1 has a fixed frame 9 on its upper end face, and a second servo motor 10 is provided inside the fixed frame 9. One end of the output shaft of the second servo motor 10 is connected to the first screw 11 through a coupling, and a second slide rod 12 is provided below the first screw 11. A second movable block 13 is inserted through the first screw 11 and the second slide rod 12, and a mechanical arm 14 is provided on the second movable block 13. The other end of the mechanical arm 14 is inserted into the second fixed block, and a second bolt 15 is inserted through the mechanical arm 14 and the second fixed block. A second nut is screwed on the other end of the second bolt 15. The second fixed block is located on the motor box, and a motor 16 is provided inside the motor box. An output shaft is provided on the motor 16, and the output shaft has threads on its outer wall. A grinding wheel 17 is screwed on the output shaft, and a spiral block 18 is screwed on the outer end of the output shaft.

[0025] Furthermore, the grinding wheel 17 forms a spiral locking structure with the output shaft of the motor 16 via the spiral block 18, and the motor 16 forms a spiral locking structure with the robotic arm 14 via the second bolt 15, thereby facilitating the disassembly and replacement of the grinding wheel 17 or the motor 16 as a whole according to the required size of the grinding roll.

[0026] The fixed frame 9 has multiple sets of fixed plates 19 on its upper surface, and rotating rods 20 are inserted between the fixed plates 19. Limiting rods 21 are inserted at both ends of the rotating rods 20, and connecting plates 22 are provided on the outer wall of the rotating rods 20. Support plates are provided on the connecting plates 22, and multiple sets of second screws 23 are inserted on one side of the connecting plates 20. The lower ends of the second screws 22 are inserted into the connecting blocks, and the connecting blocks are inserted into the third fixed blocks. Third bolts 24 are inserted into the connecting blocks and the third fixed blocks, and the other end of the third bolts 24 is screwed with a third nut. The third fixed blocks are respectively provided on the protective cover 25, and the protective cover 25 has a dust suction port 26 inside. The dust suction port 26 has an exhaust pipe above it, and the other end of the exhaust pipe is connected to an exhaust fan. It should be noted that there is a certain gap between the lower end of the second screw 23 and the connecting block, so as to ensure that the two sets of second screws 23 can drive the protective cover 25 to rise and fall.

[0027] Furthermore, the protective cover 25 forms a lifting structure with the connecting plate 22 via the second screw 24, and the protective cover 25 forms a spiral locking structure with the connecting rod via the third fixing block and the third bolt 24, which facilitates the selection of a suitable protective cover 25 for spiral installation according to the size of the roll. At the same time, the height of the protective cover 25 can be adjusted via the second screw 23.

[0028] Working Principle: When using an adjustable roll grinding machine, firstly, select a limit block 7 of the appropriate size according to the roll size to be ground. Then, start the first servo motor 2. The output shaft of the first servo motor 2 drives the bidirectional screw 3 to rotate through the coupling, so that the fixed rod 6 can be driven to slide bidirectionally through the first slide rod 4 and the first movable block 5, thereby ensuring that the first fixed block can be inserted into the limit block 7. The limit block 7 can then be screwed on by the first bolt 8, and the roll can be squeezed and limited by the limit block 7. After the roll is limited, a grinding wheel 17 of the appropriate size can be selected according to its size, and screwed on the output shaft of the motor 16 by the screw block 18. If the roll size is large, the entire motor 16 assembly can be replaced by the second bolt 15, thereby ensuring... While improving the grinding efficiency of the rolls, the stability of the grinding wheel 17 during high-speed rotation is ensured. Next, a protective cover 25 of the appropriate size can be selected according to the roll size and screwed on using the third bolt 24. This avoids the protective cover 25 being unsuitable in size, thus preventing it from affecting the device's chip shielding effect. After the protective cover 25 is screwed on, the second screw 23 can be rotated to adjust the height of the protective cover 25, allowing for timely collection of chips generated during grinding through the dust suction port 26 on the protective cover 25. During the use of this device, if it is necessary to operate the grinding wheel 17, the limit rod 21 can be removed, allowing the protective cover 25 to rotate via the rotating rod 20, thereby enabling operation of the grinding wheel 17 and its related components. This is the operating process of this adjustable roll grinding machine.

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