[0002] CNC grinding machines are machine tools that use abrasive tools to grind the surface of workpieces through CNC technology. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, abrasive belt grinders, grinders and polishers. CNC grinding machines include CNC surface grinders, CNC centerless grinders, CNC internal and external cylindrical grinders, CNC vertical universal grinders, CNC coordinate grinders, CNC forming grinders, etc. With the rapid development of the market, the blade industry has higher requirements for blades. The demand is getting higher and higher, which is the most commonly used cutting tool for slitting and cutting. Its quality is closely related to the processing technology. It is of great significance to shorten the production and processing cycle and reduce the processing cost. Most of the blades have detailed parameters. These parameters determine the processing capacity and cutting function of the tool. When selecting each blade, it is necessary to make an accurate selection based on the type of slitting material, slitting speed, slitting direction, feeding speed, slitting width and other specific parameters. The slitting machine blades are mainly used for metal plates, strips, leather, and packaging machinery slitting production lines.

[0003] For example, the patent document with the announcement number CN 101596693 B discloses a CNC precision grinding and polishing machine. It includes a welded box body, a main shaft drive system is arranged on its main support, the cylinder rod of the fast-acting cylinder of its upper plate device is fixed downward in the center of the crossbeam, the cylinder rod of the fast-acting cylinder is connected to the slow-acting cylinder, and a host computer tablet computer for motion control is arranged in its operating box, and an industrial controller and a motor drive mechanism for motion control are arranged in the electrical cabinet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The CNC grinding machine for the slitting knife edge with a dust removal function can realize efficient dust removal operation on the slitting knife edge by arranging a first mounting frame, a sliding frame, an adjusting frame, a cylinder body, a movable groove, a first limiting frame, a second limiting frame, a dust collecting box, a negative pressure box, an engaging shaft, a top fixed ball, an absorption frame, a connecting pipe, a beating strip, a rotating rod, a negative pressure fan, a hydraulic rod and an upper mold. In actual use, the staff first places the slitting knife that needs to be ground on the lower mold, and then starts the hydraulic rod at the top of the supporting frame to drive the connecting frame and the upper mold to fall stably on the lower mold and the slitting knife edge as a whole, and then starts the driving motor inside the mounting frame to drive the lower mold and the slitting knife edge as a whole to perform stable rotation and grinding. During the grinding process, the cylinder body is started again, so that the cylinder body pushes the bottom end of the adjusting frame to perform a reciprocating movement operation, and the sliding rail and the movable seat on the top of the sliding frame assist it in completing the movement, so that the lower mold as a whole moves inside the movable groove of the adjusting frame, and the surfaces of the adjusting frame at both ends The first limit frame and the second limit frame can perform a stable top fixing movement operation, and the meshing shaft on the surface of the negative pressure box can mesh and rotate with the lower mold. When the lower mold as a whole moves under the action of the first limit frame and the second limit frame, the upper mold is separated from part of the lower mold. The dust generated by grinding the slitting knife edge can be thrown into the dust collecting hood on the surface of the lower mold under the action of centrifugal force for collection. Then the dust collecting hood rotates through the beating bar on the surface of the meshing shaft to continuously squeeze and beat the dust out of the dust collecting hood. At this time, the meshing shaft performs a negative pressure suction operation inside the negative pressure box through the rotating rod and the negative pressure fan at the bottom, and the dust is quickly absorbed into the dust collecting box along the absorption frame and the connecting pipe for collection and storage. The alternating cooperation between the first limit frame and the second limit frame enables the equipment as a whole to complete the collection operation of dust on the surface of the lower mold and the slitting knife edge during the reciprocating movement of the adjusting frame, thereby improving the overall processing effect of the equipment, improving the daily grinding quality of the slitting knife edge, and reflecting the practicality of the equipment design.

[0017] The slitting knife edge CNC grinding machine with dust removal function can further improve the overall processing effect of the equipment by setting a driving motor, a first transmission plate, a transmission belt, a second transmission plate, a rotating seat, a stable seat, a connecting seat, a lower mold, a limit rod, a limit seat, an annular shaft, a rotating ball, a docking frame, an arc groove, an adjusting spring and a connecting shaft. In daily use, the staff can start the driving motor inside the installation frame, and the driving motor will drive the second transmission plate through the first transmission plate and the transmission belt to rotate the rotating seat as a whole to perform a stable rotation operation, and the rotating seat will drive the connecting seat and the lower mold as a whole to perform a stable driving operation. When the lower mold is pushed as a whole in daily life, the stable The adjusting spring inside the seat and then the connecting shaft can keep the connecting seat as a whole in a stable adjustment state. The adaptive reset adjustment operation allows the lower mold as a whole to always maintain a stable grinding state during movement and adjustment. At the same time, the limit rod at the bottom end of the second transmission disk can perform a stable docking operation with the arc groove on the surface of the docking frame on the inner wall of the mounting frame through the limit seat at the bottom end, and then perform a stable circular motion inside the arc groove through the annular shaft and the rotating ball.

The inner wall of the stabilizing seat 24 is evenly fixedly connected with an adjusting spring 35, and one end of the adjusting spring 35 is provided with a connecting shaft 36. By starting the driving motor 19 inside the mounting frame 17, the driving motor 19 drives the second transmission disc 22 through the first transmission disc 20 and the transmission belt 21, and then the rotating seat 23 is rotated stably as a whole, and the rotating seat 23 drives the connecting seat 25 and the lower mold 26 as a whole to perform a stable driving operation.

[0031] Working principle: When in use, the user first places the slitting knife that needs to be ground on the lower mold 26, and then starts the hydraulic rod 42 on the top of the support frame 15 to drive the connecting frame 43 and the upper mold 44 to fall stably on the lower mold 26 and the slitting knife edge as a whole, and then starts the driving motor 19 inside the mounting frame 17 to drive the lower mold 26 and the slitting knife edge as a whole to perform stable rotation and grinding. During the grinding process, the cylinder body 4 is started again, so that the cylinder body 4 pushes the bottom end of the adjusting frame 3 to reciprocate, and the sliding rail 40 and the movable seat 41 on the top of the sliding frame 2 assist it to complete the movement, so that the lower mold 26 is moved as a whole inside the moving groove 5 of the adjusting frame 3, and the first limit positions at both ends of the surface of the adjusting frame 3 are adjusted.

The rotating seat 23 then drives the connecting seat 25 and the lower mold 26 as a whole to drive stably. When the lower mold 26 is pushed as a whole in daily life, the The adjusting spring 35 inside the fixed seat 24 and then the connecting shaft 36 can keep the connecting seat 25 as a whole in a stable adjustment state, and the adaptive reset adjustment operation can make the lower mold 26 as a whole always maintain a stable grinding state during the movement adjustment. At the same time, the limiting rod 29 at the bottom end of the second transmission plate 22 can be stably docked with the arc groove 34 on the surface of the docking frame 33 of the inner wall of the mounting frame 17 through the limiting seat 30 at the bottom end, and then the annular shaft 31 and the rotating ball 32 perform stable arc motion inside the arc groove 34.
