[0031] The working process of the utility model is as follows: the materials are placed in the material placing bin 11, the second motor 15 is started, the rotating roller 13 in the cylindrical bin 12 is rotated, because the strip-shaped groove 14 is formed in the rotating roller 13, so the materials accumulated in the material placing bin 11 are taken away by the rotating roller 13 every circle, the materials fall from the outlet below the cylindrical bin 12 due to the gravitational potential energy, are caught by the receiving block 19 on the second electric telescopic rod 20 below, then the second electric telescopic rod 20 is retracted, the receiving block 19 reaches the middle of the two groups of rubber blocks 18, then the first electric telescopic rod 16 is extended, the long strip stick 17 clamps the materials from both ends of the materials with the rubber blocks 18, then the second electric telescopic rod 20 is retracted, the receiving block 19 does not block the triangular long plate 8, at this time, the first motor 3 is started, the unidirectional screw rod 4 is driven, until the materials are taken to the middle of the two groups of grinding rollers 29, the fourth motor 27 is started, the grinding roller 29 is driven to rotate, then the third motor 22 is started, the bidirectional screw rod 23 is rotated, drives the two groups of sliding plates 25 to move oppositely, at the same time, the first mini motor 7 and the second mini motor 10 in the first sliding block 6 and the second sliding block 9 are started, drive the two groups of first electric telescopic rods 16 to drive the long strip stick 17 to rotate, so that the materials rotate, at the same time, the two groups of grinding rollers 29 also grind the materials, until the materials are ground to the required size.

[0032] Because the second electric telescopic rod 20 drives the receiving block 19 very close to the lower end opening of the cylindrical bin 12 before the two groups of rubber blocks 18 clamp the material, the material will not bounce when it falls due to its own gravitational potential energy, and after clamping, the second electric telescopic rod 20 retracts, so that the receiving block 19 does not block the material and the clamped material, because the material is driven to rotate by the two groups of mini motors, and the two groups of grinding rollers 29 grind from the upper and lower parts of the material, and the inclined grooves at the ends of the mounting frames 26 are just clamped on the two triangular long plates 8 on both sides of the material, so the device can uniformly grind the material. After the material is ground, the two groups of grinding rollers 29 move away, the two groups of mini motors are turned off, the first motor 3 continues to drive the one-way screw 4, until the two groups of rubber blocks 18 clamp the material above the storage box 32, the first electric telescopic rod 16 retracts, so that the material naturally falls into the storage box 32. After collecting enough finished material, the worker can transport and process the storage box 32 by pulling the handle 33. The above is the working principle of the mold positioning pin outer circle grinding device.
