[0024] The bottom of the mounting plate 4 is fixedly connected with one side of the left-rotating vibration disc 1, three mounting blocks 401 are inserted into the mounting plate 4, three mounting through holes are formed in one side of the mounting plate 4, the three mounting blocks 401 are first installed in the mounting through holes of the mounting plate 4, the left-pressing positioning roller 403 is installed at the position first contacting the products, the right-pressing positioning roller 404 is installed at the position second contacting the products, and the upper-pressing positioning roller 405 is installed at the position last contacting the products, and it should be noted that the bottoms of the three positioning rollers are a certain distance away from the top of the V-shaped material groove 3, so as to prevent the three positioning rollers from being too close to the V-shaped material groove 3, thereby causing the problems of mispositioning, overlapping and material jamming of the products.

[0025] One side of each of the three mounting blocks 401 is fixedly connected with a connecting frame 402, the left-pressing positioning roller 403, the right-pressing positioning roller 404 and the upper-pressing positioning roller 405 are rotatably connected to the outside of the three connecting frames 402 respectively, the products are conveyed in the V-shaped material groove 3, when the products reach the left-pressing positioning roller 403, the left-pressing positioning roller 403 prevents the products from mispositioning from the left, then the products reach the right-pressing positioning roller 404, the right-pressing positioning roller 404 prevents the products from mispositioning from the right, finally the products reach the upper-pressing positioning roller 405, and the upper-pressing positioning roller 405 prevents the products from mispositioning from above, so that the products are stably pressed in the V-shaped material groove 3, thereby avoiding the problems of mispositioning, overlapping and material jamming of the products during conveying, and affecting the continuity and stability of the feeding device, and thus the working efficiency of the feeding device is low.

[0026] Embodiment Two: as shown in Figure 3 , Figure 5As shown, one side of the mounting plate 4 is fixedly connected with three springs 406, the three springs 406 are arrayed, the three springs 406 can keep the left pressure alignment roller 403, the right pressure alignment roller 404 and the upper pressure alignment roller 405 movable, so that the stability of the product in the V-shaped trough 3 during conveying can be ensured.

[0027] The bottom of each of the three springs 406 is fixedly connected with a fixed frame 407, the outer part of each of the three fixed frames 407 is rotatably connected with the left pressure alignment roller 403, the right pressure alignment roller 404 and the upper pressure alignment roller 405, the working principle of the three alignment rollers is the same as above, when the product deviates in the V-shaped trough, the three alignment rollers will be lifted up when the product passes through the three rollers, at this time, the three alignment rollers will drive the fixed frame 407 to rise, so that the fixed frame 407 presses the spring 406, so as to facilitate the product to pass through, avoid the poor movability of the three alignment rollers, and avoid the difficulty of the deviated product to pass through, at the same time, the reaction force of the spring 406 can also correct the deviated product to the inside of the V-shaped trough 3, so as to ensure the product to be conveyed in the correct position.

[0028] One end of the V-shaped trough 3 is fixedly connected with a pipe 5, the other end of the pipe 5 is connected with a straight vibration conveying device, the bottom of the pipe 5 is fixedly connected with the top of the supporting plate 2, the pipe 5 is supported and fixed at one end by the supporting plate 2, after the product passes through the three alignment rollers in the V-shaped trough 3, the product will enter the inside of the pipe 5, then the product will enter the straight vibration conveying device through the pipe 5, the other end of the straight vibration conveying device is a centerless grinding machine, the product will enter the centerless grinding machine through the straight vibration conveying device for processing.

[0029] The working principle of the automatic feeding device for the small-end-diameter shaft product centerless grinding is as follows:

[0030] Firstly, the operator installs the three mounting blocks 401 in the mounting through holes of the mounting plate 4, and installs the left pressure alignment roller 403 at the position first contacted with the product, installs the right pressure alignment roller 404 at the position second contacted with the product, and installs the upper pressure alignment roller 405 at the position last contacted with the product.

[0031] Secondly, the operator pours the product into the left rotary vibration plate 1, the left rotary vibration plate 1 will convey the product to the V-shaped trough 3 when working, the product will be aligned by the three alignment rollers when conveying in the V-shaped trough 3, when the product reaches the left pressure alignment roller 403, the left pressure alignment roller 403 will prevent the product from being misaligned from the left, then the product will reach the right pressure alignment roller 404, the right pressure alignment roller 404 will prevent the product from being misaligned from the right, finally, the product will reach the upper pressure alignment roller 405, the upper pressure alignment roller 405 will prevent the product from being misaligned from the top, so as to stably press the product in the V-shaped trough 3.

[0032] The left, right and upper position correction rollers 403, 404 and 405 can also be kept movable by three springs 406, and the working principle of the three position correction rollers is the same as above. When the product is offset in the V-shaped chute, the three position correction rollers will be lifted when the product passes through the three rollers. At this time, the three position correction rollers will drive the fixed frame 407 to rise, so that the fixed frame 407 presses the springs 406, thereby facilitating the product to pass through, avoiding the poor mobility of the three position correction rollers, which leads to the difficulty of passing through the offset product. At the same time, the reaction force of the spring 406 can also correct the offset product to the inside of the V-shaped chute 3, thereby ensuring that the product is correctly conveyed.

[0033] Finally, the product will enter the inside of the pipe 5 after passing through the three position correction rollers in the V-shaped chute 3, and then the product will enter the straight vibration conveying device through the pipe 5. The other end of the straight vibration conveying device is a centerless grinding machine. The product will enter the centerless grinding machine for processing after passing through the straight vibration conveying device.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application 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 replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
