[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] According to the embodiment, in combination with the accompanying drawings, a roller grinding machine includes a frame 1, a transport and material distribution mechanism 2 arranged on the frame, a first platform 3, a step-type transport mechanism 4, a grinding mechanism 5, a grinding clamping mechanism 6, a draining table 7, and a buffer area 8.

[0022] The transport and material dividing mechanism 2 further comprises a conveyor belt 9 and an electric material dividing device, wherein the electric material dividing device comprises a first electric material dividing rod 10, a second electric material dividing rod 11, a first material dividing sensor 12 and a second material dividing sensor 13. The first electric material dividing rod and the second electric material dividing rod are arranged side by side above the conveyor belt, and the first material dividing sensor is arranged between the first electric material dividing rod and the second electric material dividing rod to detect whether there is a workpiece passing through. In the initial state, the first electric material dividing rod releases a current workpiece 14 so that it is located between the two electric material dividing rods. The second material dividing sensor is arranged at the position where the previous workpiece 15 is to be transported. After detecting that the previous workpiece 15 has been moved away, it notifies the second material dividing rod to release the current workpiece 14. The first material dividing rod blocks the next workpiece 16. After the current workpiece leaves the second material dividing rod, the second electric material dividing rod is in a blocking state again, and the first electric material dividing rod releases the next workpiece 16 to enter between the two electric material dividing rods.

[0023] The step-type transport mechanism 4 can move synchronously in the left and right, front and back, and up and down directions relative to the frame. The overall movement of the step-type transport mechanism is a technology that can be easily solved. The step-type transport mechanism includes five jaws, which are the first jaw 17, the second jaw 18, the third jaw 19, the fourth jaw 20 and the fifth jaw 21 according to the moving direction of the workpiece. The left and right, front and back, and up and down directions of the five jaws are synchronously moved.

[0024] The grinding mechanism 5 includes a first grinding disc 22 and a second grinding disc 23, and the first grinding disc and the second grinding disc are driven to rotate by a motor, which also belongs to the prior art.

[0025] The grinding jaw mechanism 6 includes a first manipulator 24 and a second manipulator 25. The two sets of manipulators can move up and down synchronously. The first manipulator is located above the first grinding disc, and the second manipulator is located above the second grinding disc. The extended fingers 26 at the ends of the two sets of manipulators can be inserted into the workpiece and hold it tight.

[0026] After the workpiece is released by the second electric material dividing rod, it moves to the place to be transported, and the step-type transport mechanism is activated. The first clamping claw can clamp the workpiece from the conveyor belt and place it on the first platform. There is absorbent cotton on the first platform. The second clamping claw can clamp the workpiece from the first platform and move it to the top of the first grinding disc. The first manipulator moves from top to bottom. The extended finger of the first manipulator can be inserted into the workpiece and tighten it. The second clamping claw is released, and the workpiece is pressed by the first manipulator on the surface of the first grinding disc. The first grinding disc rotates at high speed. After grinding one side, the first manipulator clamps the workpiece. The workpiece is lifted up, the first manipulator is released after the third jaw clamps the workpiece, the third jaw can rotate 180 degrees relative to the step-type transport mechanism and move to the top of the second grinding disc, the extension finger of the second manipulator can be inserted into the workpiece and tighten it, the third jaw is released, the workpiece is pressed on the surface of the second grinding disc by the second manipulator, the second grinding disc rotates at high speed, after grinding is completed, the second manipulator clamps the workpiece and lifts up, the fourth jaw clamps the workpiece and the second manipulator is released, the fourth jaw clamps the workpiece and puts it on the surface of the draining table, and the fifth jaw takes the workpiece away from the surface of the draining table. When the second workpiece, the third workpiece, the fourth workpiece and the fifth workpiece are all on the grinding line, their working steps are consistent with the first workpiece.
