Wherein, the upper end of the heat sink 11 is provided with an air blowing groove 17 for communicating the inner cavity of the heat sink 11 with the outside, the aperture of the air blowing groove 17 is small, the upper end of the heat sink 11 is movably connected with a warning wheel 18, and the extension plate at the side of the warning wheel 18 is twisted at a certain angle, so that the heat sink 11 can not be rapidly radiated by the breathing heat exchange mechanism, when the temperature of the upper pinch roller 9 and the heat sink 11 is high, the heat conducting oil in the liquid storage cavity 16 and the air in the breathing cavity 12 are heated and expanded, so that the position of the piston block 14 can not be pushed by the expansion of the heat conducting oil, so that the heat conducting oil is expanded, the movable block 15 is jacked upwards, the expanded gas at the upper end of the movable block 15 is extruded outwards through the air blowing groove 17, and the air has a certain impact force after being blown out by the arrangement of the groove 17 with the small aperture, and the air impacts the twisted extension, and a warning sound is sent to warn the pinch roller to be overheated and pay attention to safety.

Wherein, set up the less vent 13 of aperture and gas blow tank 17, make the pinch roller 9 once rotate one hundred twenty degrees and accomplish the heat transfer of breathing, thereby through the gas flow efficiency who reduces heat transfer mechanism, enough heat can be absorbed when guaranteeing gas outgoing at every turn, and the heat production efficiency when having reduced movable block 15 and reciprocate, and avoided when movable block 15 moves down, the negative pressure chamber that its upper end formed breathes in through gas blow tank 17 fast, thereby drive warning wheel 18 rotates, cause the problem of alarm spurious triggering.

Wherein, the middle part fixedly connected with of movable block 15 upper surface presses gas pole 20, and presses the outside that the other end of gas pole 20 is located radiating seat 11 upper end for can be through setting up manual heat transfer mechanism, after radiating seat 11 sends the police dispatch newspaper because overheated, can make radiating seat 11 carry out the heat transfer under the shutdown state, ensured the quick cooling of briquetting, improved the work efficiency of blank holder machine.

The using method of the invention is as follows: firstly, replacing a lower pressing wheel 7 and an upper pressing wheel 9 with proper sizes according to the required processing size of the material to be processed, and then starting a motor 2 to process the material;

material processing: the rotating speed of the rotating end of the motor 2 is controlled through the speed reducer 3, so that the rotating speed of the driving rod 6 below is relatively slow, the driving rod 6 above is driven through the gear 5, the lower pressing wheel 7 and the upper pressing wheel 9 rotate at the same rotating speed, and therefore after materials to be processed are placed between the pressing wheels, the edges of the materials to be processed are deformed through the depression in the middle of the lower pressing wheel 7 and the protrusion in the middle of the upper pressing wheel 9, and the materials to be processed are processed;

breathing and heat exchange: when the blank pressing machine normally works, when the upper pressing wheel 9 rotates to a specific angle, the magnetic attraction of the magnetic block 10 in the inner cavity of the upper pressing wheel 9 on the movable block 15 in the middle of the heat radiating seat 11 causes the movable block 15 to overcome the elastic force of the spring 19 to move downwards, so that the heat conducting oil in the liquid storage cavity 16 extrudes the piston block 14, the piston block 14 moves outwards, so that the air in the breathing cavity 12 is blown out outwards through the vent 13, and after the magnetic attraction of the magnetic block 10 on the movable block 15 disappears, the spring 19 drives the movable block 15 to automatically reset, so that the piston block 14 automatically resets under the action of negative pressure in the liquid storage cavity 16, and new air is sucked into the breathing cavity 12 through the vent 13, so that the air in the breathing cavity 12 is continuously sucked or exhausted through the vent 13, the heat radiating seat 11 with higher temperature is sucked through the air circulation and exhausted outwards, so that the temperature of the heat radiating seat 11 is slowly increased, so that the heat radiating seat 11 can continuously absorb heat to the upper pinch roller 9 contacted with the heat radiating seat, and the heating efficiency of the heat radiating seat is reduced;

and (4) overheating warning: when the movable block 15 continuously moves to generate heat and the breathing heat exchange efficiency is smaller than the heat generation efficiency of the upper pressing wheel 9, the temperature of the upper pressing wheel 9 can be greatly increased after a certain time, and scalding hidden danger is generated, the heat conduction oil in the liquid storage cavity 16 and the air in the breathing cavity 12 are heated and expanded, and under the action of the smaller aperture of the vent 13, the piston block 14 moves upwards under the action of the expansion of the air in the breathing cavity 12, so that the heat conduction oil is pushed back upwards by the piston block 14 under the heat expanded heat conduction oil pressure, the movable block 15 overcomes the elastic force of the spring 19 to move upwards, and under the action of the pressure, the air at the upper end of the movable block 15 is discharged outwards through the air blowing groove 17 and impacts the blades on the side surface of the warning wheel 18, so that the warning wheel 18 rotates and generates sound to warn operators that the pressing wheel is overheated;

manual heat dissipation: when the temperature of the pressing wheel of the edge pressing machine is too high and the edge pressing machine is not easy to continue to process, the air pressing rod 20 is pressed downwards manually, so that the breathing heat exchange mechanism is driven to operate under the manual action, the heat dissipation seat 11 is cooled, and the temperature of the upper pressing wheel 9 is rapidly reduced.
