Working procedure

Step one, starting a tabletting part 1 to tablet a zirconium oxide material;

step two, the roller 13 generates heat in the working process, cooling water enters a cooling channel 25 through a water inlet pipe 21, then passes through a cooling channel 24 in the roller 13, and finally flows out through a water return pipe 22 to directly cool the roller 13;

step three, when the cooling water absorbing heat flows through the return pipe 22, the heat is transferred into the air chamber 311 through the heat-conducting fins 312, so that the pressure inside the air chamber 311 is increased;

step four, the pressure in the air chamber 311 pushes the piston member 313 to move, when the pressure in the air chamber 311 rises to a certain degree, the pressing plate 3131 on the piston member 313 contacts with the exhaust switch 51 to open the exhaust pipe 42, and the high-pressure gas in the air chamber 311 is rapidly ejected through the exhaust pipe 42 and the air ejecting assembly 41 to flush and clean the roller 13;

step five, after the gas in the gas chamber 311 is exhausted, the pressure in the gas chamber 311 is reduced, the piston 313 moves back and returns, the pressing plate 3131 is separated from the exhaust switch 51, the exhaust pipe 42 is closed, then the pressing plate 3131 contacts the one-way plate 54, the rotating disc 53 is driven to rotate and contacts the air inlet switch 52, the air inlet pipe 43 is opened, and the gas is supplied into the gas chamber 311;

step six, repeating the step three to the step five, and continuously and automatically cleaning the roller 13;

seventhly, in the process that the two piston members 313 move, the sliding plate 72 drives the detection rod 314 to move respectively;

when the temperatures of the two rollers 313 are consistent, the two piston members 313 synchronously move towards each other, and the detection rod 314 does not deflect;

when the two rollers 313 have large temperature difference, the two piston members 313 do not move synchronously, and the two sliding plates 72 are staggered to drive the detection rod 314 to deflect;

step eight, the deflected detection rod 314 firstly pushes the clamping plate 65 to be separated from the gear 63, then the one-way ratchet 64 is contacted with the gear 63, and the control valve 32 is adjusted through the rack plate and the deflector rod 61, so that the flow of the cooling water in the water inlet pipe 21 is adjusted, the automatic adjustment of the cooling water according to the temperatures of the two rollers 13 is realized, and the temperature of the two rollers 13 is kept consistent;

step nine, when the temperatures of the two rollers 13 are consistent, the detection rod 314 is reset, the clamping plate 65 clamps the gear 63 again, and the adjusted control valve 32 is fixed again, so that the clamping plate 65 is automatically loosened to adjust the control valve 32, and the control valve 32 is automatically fixed after the adjustment is completed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
