The working principle of the invention is as follows: the PLC controller starts a plurality of direct drive motors, materials are conveyed into the machine body 1 through the feeding pipe 101 and enter two groups of grinding mechanisms for processing after being shunted by the material dividing plate 3, when the first direct drive motor 6 drives the first driving shaft 15 to operate, the first gear 151 drives the second gear 171 and the third gear 181 to rotate relatively, the second gear 171 drives the first mounting shaft 172 to operate, the first spiral blade on the first mounting shaft 172 extracts lubricating oil in the function box 16 and conveys the lubricating oil to the oil inlet cabin 1015, because the N-stage magnetic block and the S-stage magnetic block operate on the inner surface of the stator coil 1014 under the driving of the first driving shaft 15, the stator coil 1014 generates current, the current flows to the P-type semiconductor and the cold substrate 21 after passing through the N-type semiconductor and the hot substrate, the cold substrate 21 generates a refrigeration effect according to the Peltier effect, namely the lubricating oil passing through the cold substrate 21 is cooled, the cooled lubricating oil passes through the cold base plate 21, the second oil pipe 13 and the first oil inlet path 192 and then flows into the interior of the bearing of the first bearing seat 9, so that the ball and the sliding friction piece are effectively cooled and lubricated;

meanwhile, the third gear 181 drives the second mounting shaft 182 to operate, the second helical blade on the second mounting shaft 182 extracts the lubricant in the lubricant tank 1016 and transfers it into the function tank 16, since the lubricant outlet tank 17 and the lubricant in the lubricant tank 18 are in a relative flow direction, the lubricant in the first oil inlet passage 192 and the first oil outlet passage 193 in the first bearing seat 9 flows through the bellows 14 to the second oil inlet passage 194 and the second oil outlet passage 195 in the second bearing seat 11, the bellows 14 is not influenced by the position movement of the first bearing seat 9 when the device performs the adjustment of the distance between the grinding rollers, the lubricant passing through the second oil outlet passage 195 passes through the first oil pipe 12 and flows into the lubricant tank 1016, the metal filter 10161 is impacted by the lubricant and then moves toward the metal 10163, the metal 10163 connects the stator coil 1014, when the metal 10161 contacts the 1063, the metal 10161 is electrically energized to generate magnetism, the sealing block 10165 blocks the scrap collecting cabin 10166 along with the movement of the metal filter plate 10161, the metal filter plate 10161 adsorbs scrap iron contained in the passing lubricating oil, so as to achieve the filtering effect of the lubricating oil, and the lubricating oil passing through the metal filter plate 10161 is conveyed into the functional box 16 by the oil pumping box 18, so that a complete bearing lubricating oil circulation process is formed, and the effects of efficiently cooling and filtering the bearing are achieved;

when the device stops operating, the lubricating oil is not circulated, the metal filter plate 10161 is not impacted by the lubricating oil, under the action of the spring 10164, the metal filter plate 10161 is pulled back by the spring 10164, the metal filter plate 10161 is not contacted with the metal block 10163, then the power is cut off and the magnetism is lost, the sliding chamber 10162 moves to the opening of the chip collecting chamber 10166 and is communicated with the opening, the iron chips are concentrated in the chip collecting chamber 10166 under the attraction of the self gravity and the magnetic force of the magnetic block in the chip collecting chamber 10166 and then are further processed, the first electrode plate 22 is connected with the power supply of the stator coil 1014, the current flows to the second electrode plate 23 through the electric brush 24, the second electrode plate 23 is electrified, when the dust is dispersed in the gap between the lower mounting plate 1011 and the first driving shaft 15, the second electrode plate 23 contacts the dust firstly, the dust displaying the electric charge is repelled or adsorbed, the repelled dust cannot enter the first straight motor driving 6, because the contact surface of the second electrode plate 23 and the electric brush 24 is obliquely arranged, the event is by the dust on the 23 inclined planes of adsorbed dust second electrode board to keeping away from first driving motor 6's direction landing under electric brush 24's the cleaning, prevent effectively that the dust from entering first driving motor 6 inside, prolong first driving motor 6's life always, the cylinder through PLC controller control cylinder 7 walks the footpath volume of walking, make the first bearing frame 9 that adjusts pole 702 and drive on the regulating block 701 remove, thereby realize the clearance adjustment between first grinding roller 4 and the second grinding roller 401, carry out the different intelligent processing of thickness degree to the material, make this device more intelligent, the efficient processes the processing to the material.
