Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5, the present utility model provides a technical solution: an automatic feeding plunge centerless grinding machine, including a base 1, on the top of the base 1, an installation box 3, a receiving plate 15, a centerless grinding structure 7 are fixedly installed, and on both sides of the base 1, a first mounting frame 17 and a second mounting frame 16 are respectively fixedly installed. On the first mounting frame 17, a first motor 8 is fixedly installed. On the output shaft of the first motor 8, a first lead screw 9 is fixedly sleeved. On the first lead screw 9, a moving frame 10 is threadedly sleeved. On the top of the receiving plate 15, a front baffle 21 is fixedly installed, and on the top of the receiving plate 15, a receiving groove 20 is opened. On the top of the installation box 3, a blanking box 2 is fixedly installed. On the top of the blanking box 2, a feeding funnel 4 is fixedly installed, and on one side of the blanking box 2 close to the receiving plate 15, a blanking hole is opened. Between the blanking hole and the receiving plate 15, a downward sliding plate 19 is fixedly installed. On the top of the downward sliding plate 19, side baffles 18 are fixedly installed. Inside the blanking box 2, a downward sloping blanking plate 22 is fixedly installed. On the top of the moving frame 10, a fixed rod 6 is fixedly installed. On the top of the fixed rod 6, an electric telescopic rod 5 is fixedly installed. On the output shaft of the electric telescopic rod 5, a positioning box 32 is fixedly installed. On both inner walls of the positioning box 32, second lead screws 28 are rotatably installed, and on one side of the positioning box 32, a third motor 29 is fixedly installed. The output shaft of the third motor 29 is fixedly connected to the corresponding second lead screw 28. On both second lead screws 28, moving rods 31 are threadedly sleeved, and between the two second lead screws 28, they are fixedly connected. On the bottom of both moving rods 31, clamping plates 30 are fixedly installed. The threading directions of the two second lead screws 28 are opposite. Inside the positioning box 32, a slide rail is fixedly installed. On the slide rail, two sliders are slidably installed. The two sliders are respectively fixedly connected to the corresponding moving rods 31. Through the above structural settings, first, the materials are uniformly added into the feeding funnel 4. One by one, the materials slide down the blanking plate 22 to the downward sliding plate 19, and then slide down the downward sliding plate 19 to the receiving groove 20. Through the side baffles 18 on both sides, it can prevent the materials from accidentally falling from the downward sliding plates 19 on both sides. Through the front baffle 21, it can prevent the materials from falling from the receiving plate 15. At this time, by starting the electric telescopic rod 5, it drives the downward movement of the positioning box 32. Then, by starting the third motor 29, it drives the rotation of the two second lead screws 28, which can drive the two moving rods 31 to move towards each other, and then drive the two clamping plates 30 to move towards each other, so as to clamp and fix the materials. Then, by starting the first motor 8, it drives the rotation of the first lead screw 9. The first lead screw 9 drives the leftward movement of the moving frame 10, so that the materials move above the centerless grinding structure 7. Then, reverse the output shaft of the third motor 29, and the materials can be released, so that the materials fall into the centerless grinding structure 7, and then the grinding process can be carried out. Repeating like this, the materials can be clamped and sent to the centerless grinding structure 7 one by one for automatic feeding and grinding processing.

[0028] Combined with Figures 1-5As shown in the figure, a slide bar 14 is fixedly installed on the second mounting bracket 16, and the moving bracket 10 is slidably sleeved on the slide bar 14. Through the above structural arrangement, the rotation on the second mounting bracket 16 is restricted by the slide bar 14.

[0029] Combined with Figures 1-5 As shown in the figure, two through holes are formed between the installation box 3 and the blanking box 2, and two rotating shafts 24 are rotatably installed in the installation box 3. Impact rods 23 are movably installed in both through holes. Roller wheels 25 are rotatably installed at the bottom ends of the two impact rods 23. Impact discs 26 are fixedly sleeved on the two rotating shafts 24. Chain wheels 11 are fixedly sleeved at one ends of the two rotating shafts 24. The same chain 12 is sleeved between the two chain wheels 11. Return springs 27 are sleeved on the two impact rods 23. One ends of the two return springs 27 are fixed on the corresponding impact rods 23, and the other ends of the two return springs 27 are fixed on the inner walls of the corresponding through holes. The two rotating shafts 24 are respectively located at the eccentric positions of the corresponding impact discs 26. Through the above structural arrangement, in order to prevent the material from being blocked when it is discharged from the blanking plate 22, the corresponding rotating shaft 24 and the chain wheel 11 can be driven to rotate by starting the second motor 13. The two chain wheels 11 can be driven to rotate simultaneously through the chain 12, so that the two rotating shafts 24 can be driven to rotate simultaneously, and the two impact discs 26 can be driven to rotate. The two impact discs 26 repeatedly strike the corresponding roller wheels 25, so that the two impact rods 23 can be driven to move up and down reciprocally. The two impact rods 23 repeatedly strike the blanking plate 22, so that the material on the blanking plate 22 can be shaken, preventing the material from being blocked on the blanking plate 22.

[0030] Working principle of the utility model: First, the materials are uniformly added into the feeding funnel 4. The materials slide down one by one along the blanking plate 22 to the sliding plate 19, and then slide down along the sliding plate 19 into the receiving groove 20. The side baffles 18 on both sides can prevent the materials from accidentally falling from the sliding plates 19 on both sides, and the front baffle 21 can prevent the materials from falling from the receiving plate 15. At this time, the electric telescopic rod 5 is started to drive the positioning box 32 to move downward. Then, the third motor 29 is started to drive the rotation of the two second lead screws 28, which can drive the two moving rods 31 to move towards each other, and then drive the two clamping plates 30 to move towards each other, so as to clamp and fix the materials. Then, the first motor 8 is started to drive the rotation of the first lead screw 9. The first lead screw 9 drives the moving frame 10 to move to the left, so that the materials move above the centerless grinding structure 7. Then, the output shaft of the third motor 29 is started in the reverse direction to loosen the materials, so that the materials fall into the centerless grinding structure 7 for grinding treatment. This process is repeated to clamp and feed the materials one by one onto the centerless grinding structure 7 for automatic feeding and grinding treatment. In order to prevent the materials from being blocked when feeding on the blanking plate 22, the second motor 13 can be started to drive the rotation of the corresponding rotating shaft 24 and the sprocket 11. Through the chain 12, the two sprockets 11 can be driven to rotate simultaneously, and then the two rotating shafts 24 can be driven to rotate simultaneously, and then the two striking discs 26 can be driven to rotate. The two striking discs 26 repeatedly strike the corresponding rollers 25, which can drive the two striking rods 23 to move up and down reciprocally. The two striking rods 23 repeatedly strike the blanking plate 22, so that the materials on the blanking plate 22 can be shaken to prevent the materials from being blocked on the blanking plate 22. The utility model has a simple structure and is easy to use. The automatic feeding centerless grinding machine can automatically feed materials through the automatic sliding structure and the automatic clamping structure, with high feeding efficiency and increased working stability.
