Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing equipment, in particular to an automatic grinding device and method for a grinding wheel blade. Background Art

[0002] Circular blades are a key component of slitting machines. The choice of slitting blade is generally determined by the type and thickness of the material being slit. Slitting blades typically operate in two types: square and circular. Square blade slitting involves attaching the blade to the slitting machine's turret like a razor. As the material is being slid, the blade is lowered, cutting the material longitudinally to achieve the desired slitting effect. Circular blade slitting primarily involves upper and lower disc shearing and circular extrusion slitting. Since the blade needs to cut materials continuously during operation, it wears out quickly. Commonly used blades will generally become blunt after a few hours of use, and cutting will be more laborious. At this time, the chain blade needs to be re-sharpened. In the existing technology, it is still necessary to manually press the handle control part to drive the grinding wheel part to grind the chain saw blade. Due to the low precision of manual control, the consistency of the chain saw blade is poor, and the movement process of the grinding wheel part used for grinding is actually swinging around the extension arm at the tail of the handle control part and the shaft pin connecting the rotating arm part. If a good grinding effect of the blade is to be ensured, it is necessary to ensure that the grinding wheel used for each grinding is consistent. After the grinding wheel has been working for a period of time, the outer diameter of the grinding wheel becomes smaller. At this time, the grinding wheel needs to be replaced to ensure a better grinding effect.

[0003] This case was created to solve the above problems. Summary of the Invention

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0026] like Figure 1-6 As shown: An automatic grinding device and method for a grinding wheel blade, including a base plate 1 and a grinding wheel 4. A fixed plate 2 and a base 10 are fixedly provided on the base plate 1. A first drive motor 3 is fixedly provided on the fixed plate 2. The output end of the first drive motor 3 is connected to the grinding wheel 4. The grinding wheel 4 is covered with a protective cover 5. The end of the protective cover 5 is connected to a rotating structure. A grinding block 17 is provided under the grinding wheel 4. The top of the grinding block 17 contacts the bottom end of the grinding wheel 4. The grinding block 17 is used to grind the grinding wheel 4. A flip cover 16 is provided on the base 10. The bottom surface of the flip cover 16 is connected to a flip structure. The bottom surface of the grinding block 17 is smooth, and the surface of the flip cover 16 is also relatively smooth, so that the grinding block 17 can be slidably connected to the flip cover 16.

[0027] The working principle of the rotation structure is as follows: the second drive motor 12 drives the worm 7 to rotate, thereby driving the first transmission gear driven by the worm to rotate counterclockwise, and then the connecting bar 9 fixedly connected to it is driven to rotate upward, thereby driving the protective cover 5 to rotate upward and away from the grinding wheel 4. At this time, the grinding wheel with a smaller outer diameter can be replaced to ensure a better grinding effect.

[0028] The rotating structure includes a worm 7, a first transmission gear 8, a connecting bar 9, and a limiting rod 11. The end of the protective cover 5 is fixedly connected to one end of the connecting bar 9, and the other end of the connecting bar 9 passes through the limiting rod 11 and is fixedly connected to the first transmission gear 8. The connecting bar 9 and the limiting rod 11 are rotationally connected. The limiting rod 11 fixes the first transmission gear 8. The rotation of the first transmission gear 8 drives the connecting bar 9 fixed to it to rotate together.

[0029] The first transmission gear 8 is rotationally connected to the limit rod 11. A worm 7 is provided under the first transmission gear 8. The worm 7 and the first transmission gear 8 are meshed with each other. A worm transmission is performed between the worm 7 and the first transmission gear 8. One end of the worm 7 is rotationally connected to the limit plate 13, and the other end of the worm 7 passes through the limit plate 13 and is connected to the output end of the second drive motor 12.

[0030] The second drive motor 12 is fixed on the extension plate 6, and the extension plate 6 is fixed on the fixed plate 2. The fixed plate 2 is located on the left side of the grinding block 17 and the base 10 to ensure that the grinding block 17 does not hit the extension plate 6 when moving left.

[0031] The grinding block 17 is located directly below the grinding wheel 4 and the two are in contact. An empty slot is provided in the middle of the grinding block 17. Teeth 18 are fixed on the upper and lower surfaces of the empty slot at equal intervals. A rotating gear 19 is engaged in the middle of the teeth 18. The rotating gear 19 is connected to the output end of the third drive motor 14. The third drive motor 14 is located on the support plate 15, and the support plate 15 is fixed to the base 10. The third drive motor 14 drives the rotating gear 19 to rotate clockwise. The rotating gear 19 has teeth on the circumferential half and no teeth on the other half. Therefore, when When the rotating gear 19 rotates, when the teeth on the rotating gear 19 mesh with the teeth 18 located above it, the grinding block 17 is driven to move to the right. As the rotating gear 19 continues to rotate until the teeth on it mesh with the teeth 18 located below it, the grinding block 17 is driven to move to the left. The rotating gear 19 is driven to rotate continuously by the third drive motor 14, thereby realizing the left and right reciprocating motion of the grinding block 17, thereby realizing the grinding of the grinding wheel 4 by the grinding block 17, ensuring that the frequency and speed of each grinding of the grinding wheel are kept consistent.

[0032] The flip structure includes a flip cover 16, a second rotating gear 22, and a shift column 23. The shift column 23 is located inside the base 10 and is connected to the inner wall of the base 10. A fixed column 21 fixedly connected to the inside of the base 10 is provided on the outside of the shift column 23. A tooth groove 20 is provided on the shift column 23. An empty groove is provided on the base 10 below the two flip covers 16. The size of the empty groove is larger than the sum of the length of the two flip plate covers 16 after flipping and the length of the grinding block 17. The end of the flip cover 16 is located inside the base 10, and the fixed support of the flip cover 16 is achieved by the support of the base 10.

[0033] Working principle of the flip structure: A micro cylinder is connected to the bottom of the shift column 23, which drives the shift column 23 to move upward, thereby driving the second rotating gear 22 engaged with it to rotate downward through the tooth groove 20 thereon, thereby driving the flip cover 16 to flip downward, and then allowing the grinding block 17 to fall into the empty slot below, thereby realizing convenient replacement of the grinding block 17.

[0034] The tooth groove 20 formed on the shifting post 23 is engaged with the second rotating gear 22 . The second rotating gear 22 is fixed below the flip cover 16 .
