[0004] During the use of the raising machine, the needles of the raising roller will become blunt, resulting in poor subsequent raising effect. Currently, manual handheld grinding blocks are often used to grind the needles on the raising roller, but the grinding efficiency is not high. Summary of the invention

[0005] In order to improve the grinding efficiency of a raising machine, the present application provides a needle grinder for a raising machine.

[0006] The present application provides a needle grinder for a raising machine, which adopts the following technical solution:

[0007] A needle grinder for a napping machine comprises a frame, a grinding assembly, a toggle assembly and a moving assembly, wherein the grinding assembly comprises a needle grinding part, and the needle grinding part comprises a grinding wheel for grinding a napping roller and a grinding motor, wherein the grinding wheel is rotatably connected to the frame, the grinding motor is used to drive the grinding wheel to rotate, the toggle assembly is used to drive the rotating disk to rotate and align the grinding wheel with the adjacent side wall of the napping roller that has not been ground yet, and the moving assembly is used to drive the frame to move along the axial direction of the napping roller.

[0008] By adopting the above technical scheme, when the staff needs to grind the needles on the raising roller, the staff puts the grinding wheel against the raising roller that needs to be polished, and then starts the grinding motor to drive the grinding wheel to rotate. Then the staff rotates the raising roller so that the grinding wheel can grind the needles distributed circumferentially on the raising roller. Then the staff starts the moving component, and the moving component drives the frame to move along the length direction of the raising roller as a whole to grind the needles on the entire raising roller fan. Then the staff can start the toggle component and rotate the rotating disk so that the grinding wheel is abutted against another unpolished raising roller. Repeat the above steps until all the raising rollers of the raising machine are polished. The needle grinder reduces the work intensity of the staff and improves the polishing efficiency of the raising machine.

[0009] Optionally, the grinding assembly also includes a sliding member that drives the grinding wheel to move, and the sliding member includes a sliding frame and a sliding cylinder. The sliding frame is slidably connected to the frame in a direction close to or away from the raising roller, and the grinding wheel and the grinding motor are both arranged on the sliding frame. The sliding cylinder is arranged on the frame, and the sliding cylinder is used to drive the sliding frame to move.

[0010] By adopting the above technical solution, when the grinding assembly needs to grind another raising roller, the staff drives the rotating disk to rotate by toggling the assembly, the staff drives the piston rod of the sliding cylinder to extend and retract, the sliding cylinder drives the sliding frame to move, and the sliding frame drives the grinding wheel and the grinding motor to move away from the raising roller, thereby reducing the probability of collision between the raising roller and the grinding wheel during the rotation of the rotating disk.

[0011] Optionally, the grinding assembly further includes an adjusting tube, wherein the adjusting tube is sleeved on the rotation axis of the grinding wheel and abuts against the side wall of the raising roller.

[0012] By adopting the above technical solution, the piston rod of the sliding cylinder is extended, so that the sliding frame moves toward the direction of the raising roller until the adjusting tube abuts against the side wall of the raising roller. At this time, the staff can change the distance from the grinding wheel to the axis of the raising roller by changing the diameter of the adjusting tube, so that the grinding amount of the raising roller by the grinding wheel is changed. The grinding component has a simple structure and is easy for the staff to operate.

[0013] Optionally, the grinding assembly further includes a fine grinding piece, which includes an oil stone and a movable cylinder. The oil stone is slidably connected to the frame along the sliding direction of the sliding frame, and the movable cylinder drives the oil stone to slide.

[0014] By adopting the above technical solution, after the grinding wheel completes grinding the raising roller, the toggle assembly drives the rotating disk to rotate, and the rotating disk drives the raising roller to rotate to the work station of the fine grinding part. When the needles of the raising roller need to be ground, the staff can extend the piston rod of the mobile cylinder so that the oil stone abuts against the needles on the raising roller. The oil stone further grinds the needle tips of the raising roller, thereby improving the grinding quality of the raising roller.

[0015] Optionally, the toggle assembly includes a toggle disk, a toggle motor, a mounting block, and a mounting part for setting the mounting block on the raising machine body. The toggle disk is rotatably connected to the mounting block, and the toggle disk is provided with a plurality of grooves that cooperate with the raising roller. The toggle motor is used to drive the toggle disk to rotate.

[0016] By adopting the above technical solution, when the staff needs to drive the rotating disk to rotate, the staff can start the toggle motor, and the toggle motor drives the toggle disk to rotate. The groove on the toggle disk cooperates with the raising roller. The rotation of the toggle disk causes the rotating disk to rotate, thereby changing the relationship between the raising roller and the polishing assembly. The toggle assembly has a simple structure and is easy to operate.

[0017] Optionally, the mounting member includes a mounting frame, a mounting plate, a mounting screw and a mounting plate, the mounting frame is clamped on the cloth guide rod, the mounting plate is rotatably connected to the mounting frame, one end of the mounting screw is arranged on the mounting frame, the mounting plate is threadedly connected to the mounting screw, the mounting plate abuts against the side of the mounting plate away from the cloth guide rod, and the mounting frame abuts against the cloth guide rod.

[0018] By adopting the above technical solution, the mounting piece is used to install the mounting block on the raising machine body. The staff first places the mounting frame on the abutment roller, and then rotates the mounting plate. The mounting plate and the mounting frame are both abutted against the cloth guide rod. Then the staff can thread the mounting plate onto the mounting screw, so that the mounting plate is pressed against the side of the mounting plate away from the cloth guide rod. The mounting plate and the mounting frame clamp the cloth guide rod. The mounting piece has a simple structure and is suitable for raising machines of different sizes.

[0019] Optionally, the moving assembly includes a limiting wheel, a guide wheel, a rotating frame, a moving motor and an abutment cylinder, the length direction of the limiting wheel is perpendicular to the axial direction of the cloth guide rod, the limiting wheel is rotatably connected to the sliding frame, the limiting wheel abuts against the cloth guide rod, the rotating frame is rotatably connected to the sliding frame along the length direction of the cloth guide rod, the length direction of the guide wheel is perpendicular to the length direction of the guide wheel, the guide wheel is rotatably connected to the rotating frame, the moving motor drives the guide wheel to rotate, and the abutment cylinder is used to drive the rotating frame to rotate.

[0020] By adopting the above technical solution, it is first necessary to cooperate the limiting wheel with the cloth guide rod, and then drive the rotating frame to rotate through the abutment cylinder, so that the guide wheel abuts on the cloth guide rod, and the cloth guide rod and the guide wheel are kept in an abutment state through the limiting wheel. Then the staff starts the moving motor, and the moving motor drives the guide wheel to rotate. The guide wheel moves relative to the cloth guide rod, and the grinding assembly moves along the axial direction of the raising roller and grinds the raising roller. The moving assembly has a simple structure and is easy for the staff to operate.

[0021] Optionally, the moving assembly further comprises an abutment wheel, the abutment wheel is located on a side of the moving assembly away from the grinding assembly, the abutment wheel is rotatably connected to the base, and the abutment wheel abuts against a side wall of the raising machine body.

[0022] By adopting the above technical scheme, only through the cooperation between the limiting wheel, the guide wheel and the cloth guide rod, when the sliding member drives the grinding wheel to move toward the napping roller and abuts against the cloth guide roller, the frame is subjected to a reaction force, the frame is prone to rotate, and the grinding wheel and the napping roller are misaligned, and the grinding wheel cannot grind the napping roller; through the abutment wheel, and the abutment wheel is located on the side of the moving component away from the grinding component, the abutment wheel always abuts against the napping machine body, when the sliding member drives the grinding wheel to move toward the napping roller and abuts against the cloth guide rod, the reaction force received by the frame is absorbed by the abutment wheel, thereby reducing the frame from flipping over, ensuring that the grinding wheel abuts against the napping roller, and the abutment wheel improves the reliability of the grinding component.

[0023] Optionally, the frame includes a base, a lifting platform and a lifting assembly, the lifting platform is slidably connected to the base in a vertical direction, the lifting assembly includes a rack, a gear and a lifting motor, the length direction of the rack is parallel to the sliding direction of the lifting platform, the rack is arranged on the frame, the gear is rotatably connected to the lifting platform, the gear is meshed with the rack, the lifting motor is used to drive the gear to rotate, and the moving assembly and the grinding assembly are arranged on the lifting platform.

[0024] By adopting the above technical scheme, the sizes of the raising machines are different, and the heights of the rotating disks are different. The staff starts the lifting motor, and the lifting motor drives the gear to rotate. The gear engages with the rack, and the gear drives the lifting platform to move vertically on the base. Then the staff places the limiting wheel on the cloth guide roller, and then uses the lifting assembly to bring the lifting platform and the base closer together until the limiting wheel abuts against the cloth guide roller, and then abuts against the cylinder, so that the guide wheel abuts against the cloth guide rod, and then continues to move the lifting assembly and the base closer together. Since the moving assembly is on the lifting platform, the base will be off the ground, so that the abutting wheel remains abutted against the raising machine body, and the lifting assembly is used to make the equipment suitable for raising machines of different sizes.

[0025] Optionally, a control component is also provided on the base, and the control component includes two trigger switches and a controller. The controller is provided on the base, and the two trigger switches are distributed along the length direction of the raising roller. The trigger switch is provided on the raising machine body, and the base is located between the two trigger switches. The trigger switch is used to output a trigger signal when the moving component reaches a specified position. The controller is electrically connected to the trigger switch. The controller is used to receive the trigger signal and control the moving component to stop and drive the piston rod of the sliding cylinder to retract, and control the toggle motor to drive the toggle disk to rotate after a set time, and the toggle disk drives the adjacent unpolished raising roller to correspond to the polishing component, and controls the piston rod of the sliding cylinder to extend and controls the moving component to move in the opposite direction after a set time.

[0026] By adopting the above technical scheme, in the process of the moving component driving the grinding component to move, when the moving component moves to the set position, the moving component triggers the trigger switch, and the trigger switch receives the trigger signal. At this time, the moving motor stops rotating, the grinding component stops moving, and the piston rod of the sliding cylinder is retracted, so that the grinding wheel is away from the raising roller. Then the toggle motor drives the toggle disk to rotate, and the groove on the wave disk cooperates with the raising roller to drive the rotating disk to rotate, so that the adjacent unground raising roller corresponds to the grinding wheel, and then the piston rod of the sliding cylinder is extended, so that the grinding wheel abuts against the raising roller, and the moving motor rotates in the opposite direction, driving the grinding component to move in the opposite direction. The control component reduces manual intervention and reduces the labor intensity of the staff.
