[0002] The grinding machine removes the material on the surface of the workpiece by the high-speed rotation of the grinding tool, so as to achieve the required dimensional accuracy, shape accuracy and surface roughness. There are many types of grinding machines. Among them, the double-end surface grinding machine is a device that can grind the two end surfaces of the material at the same time. It has two grinding wheels. When grinding, the two grinding wheels rotate at the same time to grind the two end surfaces of the material. In mass production, it can significantly improve the processing efficiency and reduce the production cost.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Please refer to the attached Figures 1 to 4 As shown, a feeding tray of a double-sided grinding machine in an embodiment of the present invention includes a grinding machine main body 1 and a feeding tray 3. A back plate 2 is fixedly connected above the machine table of the grinding machine main body 1. The feeding tray 3 is rotatably connected to the back plate 2. An inlet component 4 is arranged outside the feeding tray 3. Materials enter the feeding tray 3 through the inlet component 4. A part of the feeding tray 3 is located between the two grinding wheels of the grinding machine main body 1. The materials are conveyed to the grinding position as the feeding tray 3 rotates, and the entering materials are ground by the rotation of the grinding wheels.

[0029] Among them, the feeding tray 3 includes a turntable main body 301. A plurality of outer jacks 302 and inner jacks 303 are evenly spaced at the periphery of the turntable main body 301. A through groove 304 is arranged between the outer jack 302 and the inner jack 303. The outer end of the through groove 304 is open. Through the settings of the outer jack 302 and the inner jack 303, two materials can be accommodated simultaneously on the same radius of the turntable main body 301, thereby effectively accelerating the feeding speed; arranging the through groove 304 between the outer jack 302 and the inner jack 303 can prevent the materials from getting stuck and is also convenient for the coolant to flow out.

[0030] There are two feeding components 4, including a feeding hopper 401. An arc-shaped bottom shell 402 is arranged at the lower end of the feeding hopper 401. A guide groove 405 is fixedly connected to the lower end of the arc-shaped bottom shell 402. A through hole 406 is arranged at the end of the guide groove 405. The two through holes 406 respectively correspond to the outer jack 302 and the inner jack 303. The materials enter the feeding tray 3 orderly through the feeding component 4, and the two feeding components 4 supply materials to the outer jack 302 and the inner jack 303 respectively.

[0031] As an implementation manner of the present utility model, please refer to the attached drawings. Figure 4 As shown, the feeding assembly 4 further includes a material distributing wheel 403. The material distributing wheel 403 is rotatably connected inside the arc-shaped bottom shell 402 and is driven by an external motor. A plurality of grooves 404 are formed at the outer end of the material distributing wheel 403. When the material distributing wheel 403 rotates driven by the motor, the materials inside the feeding hopper 401 will fall into the grooves 404. Among them, the size of the grooves 404 only allows one material to enter. As the material distributing wheel 403 rotates, the materials fall into the guide groove 405 and are stacked up orderly.

[0032] In this embodiment, please refer to the attached drawings. Figure 1 As shown, a pushing assembly 5 is provided at the lower end of the feeding assembly 4. Through the setting of the pushing assembly 5, the materials in the guide groove 405 can enter the holes of the feeding tray 3.

[0033] Specifically, the pushing assembly 5 includes a cylinder 501. The extending end of the cylinder 501 is fixedly connected with two ejector pins 502. The ends of the two ejector pins 502 respectively extend into two through holes 406. The cylinder 501 is fixedly connected with the machine table of the grinding machine main body 1 through a mounting bracket 503. During feeding, the cylinder 501 extends, driving the two ejector pins 502 to eject, so as to push the materials at the lowermost end in the two guide grooves 405 into the outer insertion hole 302 and the inner insertion hole 303. Then the ejector pins 502 reset, and the materials on the upper side fall, waiting for the next pushing.

[0034] As an implementation manner of the present utility model, please refer to the attached drawings. Figure 1 and Figure 2 and Figure 5 As shown, a guide chute 6 is provided below the feeding tray 3. An unloading assembly 8 is provided on one side of the guide chute 6. The unloading assembly 8 is used to separate the materials after grinding from the feeding tray 3, and the separated materials fall into the guide chute 6.

[0035] Specifically, the unloading assembly 8 includes a bracket 801. Two vertically arranged spray nozzles 802 are fixedly connected to the upper end of the bracket 801. The two spray nozzles 802 respectively correspond to the outer insertion hole 302 and the inner insertion hole 303. The provided spray nozzles 802 can spray water flow, and the materials in the outer insertion hole 302 and the inner insertion hole 303 are washed out by the impact of the water flow.

[0036] In addition, to prevent the materials from flying out of the guide chute 6, a baffle 7 is fixedly connected to the other side of the feeding tray 3 corresponding to the unloading assembly 8. The baffle 7 can play a blocking role to prevent the materials from flying out.

[0037] As an implementation manner of the present utility model, please refer to the attached drawings. Figure 1As shown in the figure, a servo motor 9 is fixedly connected to the rear side of the back plate 2. The output end of the servo motor 9 is fixedly connected to the feeding tray 3. The feeding tray 3 is driven to rotate by the servo motor 9. The servo motor 9 can achieve precise angle and speed control to ensure the accurate rotation angle and speed of the feeding tray 3.

[0038] Working principle: The material is put into the feeding hopper 401 of the feeding component 4. The material inside the feeding hopper 401 will fall into the groove 404. As the distributing wheel 403 rotates, the material falls into the guiding groove 405 and accumulates orderly; afterwards, the air cylinder 501 extends, driving the two ejector pins 502 to eject, so as to push the materials at the lowermost ends in the two guiding grooves 405 into the outer insertion holes 302 and the inner insertion holes 303. Through the settings of the outer insertion holes 302 and the inner insertion holes 303, two materials can be accommodated simultaneously on the same radius of the turntable body 301, thus effectively accelerating the feeding speed; the polished materials are turned out from the lower west side of the feeding tray 3, and the material is separated from the feeding tray 3 through the arranged discharging component 8. The separated material falls into the guiding groove 6 to complete the discharging.

[0039] The above has described in detail an embodiment of the present utility model, but the content described is only the preferred embodiment of the present utility model and cannot be considered as used to limit the implementation scope of the present utility model. All equal changes and improvements made according to the application scope of the present utility model shall still fall within the patent coverage scope of the present utility model.
