Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to an automatic feeding mechanism for a centerless grinder. Background Art

[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding. Therefore, a loading mechanism for a centerless grinder is derived.

[0003] When the existing centerless grinder loading mechanism is feeding, the material placement may not be qualified and needs to be re-fed, which requires manual adjustment, which not only increases the labor cost, but also reduces the work efficiency and production efficiency. Therefore, we propose an automatic feeding mechanism for centerless grinder. Utility Model Content

[0029] See also Figure 4 A second motor 31 is fixedly connected to the back of the feeding platform 3, and a conveying crawler 32 for conveying materials is dynamically connected to the front output end of the second motor 31.

[0030] See also Figure 6 An adjustment assembly 5 is installed on the top of the feeding table 3. The adjustment assembly 5 further includes a fixed shell 51. A support rod 53 is fixedly connected to the bottom of the inner wall of the fixed shell 51. A spring 54 is sleeved on the outer surface of the support rod 53. The upper end of the spring 54 abuts against an adjustment block 52, and the inner wall of the adjustment block 52 is slidably connected to the outer surface of the support rod 53. The lower end of the spring 54 abuts against the inner bottom wall of the fixed shell 51. A rotating shaft 55 is rotatably connected to the center of the right side of the adjustment block 52. The left and right sides of the outer surface of the rotating shaft 55 are rotatably connected to a rotating block 56. In this embodiment, the cross section of the rotating block 56 is fan-shaped. A handle 58 is fixedly connected to the top of the adjustment block 52, and a plurality of engaging holes 57 are opened on the back of the fixed shell 51.

[0031] By setting the adjustment component 5, specifically the adjustment block 52 of the adjustment component 5, it is possible to block the unqualified materials that are transported to the conveyor belt 32 through the feeding component 2 and driven by the conveyor belt 32 under the action of the adjustment block 52.

[0032] See also Figure 1 , Figure 4 and Figure 5 The housing 1 is provided with a return hole 12, and a return bin 33 connected to the return hole 12 is fixedly connected to the front of the feeding platform 3. The right side of the return bin 33 is fixed to the housing 1 and connected to the return hole 12. The adjustment block 52 has a stop arm 521 extending toward the return bin 33. In this embodiment, during the transmission process of the conveyor belt 32, due to the continuous movement of the conveyor belt 32, unqualified materials will leave the conveyor belt 32 along the raised inclined surface on the stop arm 521 of the adjustment block 52 and fall into the return bin 33. In more detail, the recovery bin 33 is provided with an inclined surface inclined toward the return hole 12. The unqualified materials initially judged to be placed in the return bin 33 are returned to the material placement platform 21 along the inclined surface for re-feeding and placement. At the same time, the user can adjust the adjustment block 52 by pulling the handle 58 according to the size of the material, avoiding excessive participation of manpower, reducing labor costs, and improving the convenience and inclusiveness of the mechanism.

[0033] See also Figure 1 , Figure 4 and Figure 7 A sliding block 4 is slidably connected to the top of the feeding platform 3, and an adjustment component 5 is fixedly connected to the top of the feeding platform 3. By setting the sliding block 4, it is specifically realized to constrain the placement of qualified materials. The user can adjust according to the size of the material by pulling the sliding blocks 4 on both sides to ensure that the material is in a straight line, thereby improving the neatness of the placement, improving the applicability of the feeding platform 3, and increasing the inclusiveness of the mechanism.

[0034] A specific application of this embodiment is: when in use, the user can set the adjustment component 5 and the sliding block 4 according to his own needs. In more detail, the adjustment block 52 is driven by pressing or lifting the handle 58, and the adjustment block 52 drives the rotating block 56. When the handle 58 is pressed, the adjustment block 52 drives the rotating block 56 to move downward. Because the rotating block 56 is fan-shaped, the rotating block 56 will contact the shell 1 again and rotate upward through the rotating shaft 55 to make the adjustment block 52 move downward. Because the spring 54 is arranged in the fixed shell 51, the adjustment block 52 will not fall due to its own gravity. When the pressure stops, the rotating block 56 will It automatically engages in one of the engaging holes 57. When it is lifted upward, press the handle 58 and then lift it upward. At the same time, the user can pull the sliding blocks 4 on both sides to adjust the width suitable for the material to pass according to their own needs. After adjustment, the material is placed on the material placement table 21. The material placement table 21 is set as an inclined surface. The material will slide to the rear side due to gravity. Start the first motor 22. The first motor 22 drives the connecting rod 24 through the rotating rod 23. The connecting rod 24 drives the first feeding block 25. The first feeding block 25 then drives the second feeding block 26 to slide up and down along the inner wall of the shell 1 through the sliding connecting plate 27. The sliding connecting plate 27 slides up and down in the sliding groove 13, and the rotating rod 23 performs a circular motion. When the first motor 22 rotates half a circle, the connecting rod 24 rotates when the rotating rod 23 rotates. When the connecting rod 24 rotates, the first feeding block 25 moves downward with the connecting rod 24, and the material comes to the first feeding block 25. When the first motor 22 rotates one circle, the first feeding block 25 moves upward. Because the top of the first feeding block 25 is set as an inclined surface, the material will be brought to the fixed block 11. The top of the fixed block 11 is set as an inclined surface. The movement principle of the second feeding block 26 is the same as that of the first feeding block 25. Similarly, The top of the second feeding block 26 is also set as an inclined surface. After the first motor 22 rotates for two weeks, the material comes to the conveyor belt 32, and the second motor 31 is started to drive the conveyor belt 32. The conveyor belt 32 drives the material to the adjustment component 5. The raised part of the stop arm 521 of the adjustment block 52 will block the unqualified materials, and the unqualified materials will be sent back to the material placement table 21 through the return bin 33 and the return hole 12 for transportation again. Because the conveyor belt 32 keeps driving the material to move and will constrain the qualified materials through the sliding block 4, the materials move in a row and can be transported to the next step.
