Before the extruder is not regulated, the speed of the pushing screw of the extruder is set to be the lowest speed (preliminary setting) of the extruder body during normal extrusion operation, the extruded material is in a parabolic state, meanwhile, the material pressing speed of the two tabletting rollers 41 is matched with the material extrusion speed of the extruder, when the speed of the extruder is regulated, the material falling onto the two tabletting rollers 41 forms accumulation (which is caused by the fact that the tabletting speed is smaller than the discharging speed of the extruder), when the material accumulates to a certain weight (the accumulated material on the two tabletting rollers 41 does not overflow and drop outwards from the two tabletting rollers 4), the weight of the material can enable the rotating shaft 52 to rotate towards one end opposite to the extruder, the rotating shaft 52 overcomes the resistance action of a regulating piece and the gravity

increase the extrusion speed of the two tabletting rollers 41 on the material to prevent the material from being seriously piled on the tabletting rollers to cause material dripping and overflowing, the flow speed of condensed water is increased due to the increased extrusion speed to increase the heat absorption effect on the material on the tabletting rollers 41, the forming after tabletting of the material (the material discharged by the extruder is a specific heat and viscous fluid material and needs to be cooled and solidified) is facilitated, the tabletting speed is increased, the transportation speed of the sheet-shaped material by the conveyor 1 and the crushing speed of the coarse crushing roller 2 are correspondingly increased, the accumulation of the sheet-shaped material on the conveyor 1 and the influence on the size of the material crushed by the subsequent coarse crushing roller are avoided, the dynamic balance of the tabletting speed and the discharging speed of the extruder is finally realized, the adjusting step can be greatly reduced, and the method is more convenient and rapid, meanwhile, the phenomenon of flash is avoided, when the supporting plate 43 carries out parabolic motion, in order to ensure that the rotation of the rotating shaft 52 is not influenced by other external factors, the connecting hose 47 is adopted and is suspended (suspended arrangement is adopted, so that when the supporting plate 43 carries out motion, the connecting hose 47 can be prevented from contacting the ground, the weight on the supporting plate 43 is prevented from being lightened, the rotation of the rotating shaft 52 is prevented from being influenced, the whole adjusting process is suspended), one end of the connecting hose is connected with the tabletting roller 41, the other end of the connecting hose is fixedly arranged on the conveyor 1, and when the initially arranged machine body works, the condensation cavity, the liquid inlet hard pipe 46, the liquid outlet hard pipe 48, the connecting hose 47 and the two tabletting rollers 41 are filled with liquid, when the discharging speed of the extruder is regulated, the flow speed of condensed water is inevitably accelerated, and because of the condensation cavity in advance, the liquid inlet hard tube 46, the liquid outlet hard tube 48, the connecting hose 47 and the two tabletting rollers 41 are filled with liquid, the flow speed of condensed water is only increased, the weight of the condensed water in the condensation cavity, the liquid inlet hard tube 46, the liquid outlet hard tube 48, the connecting hose 47 and the two tabletting rollers 41 acting on the supporting plate 43 is not influenced, the influence on the rotation of the rotating shaft 52 caused by the change of the weight of the condensed water (the weight increase can cause the rotating shaft 52 to excessively rotate and cause a great deal of loss of electric energy) can be avoided, the material guide plate 410 is arranged, the rotating speed of the material pushing screw can be quickly regulated to a required speed when the speed regulation of the extruder is carried out, the materials discharged by the extruder can fall onto the material guide plate 410 and are guided into a tabletting gap between the two tabletting rollers 41 through the material guide plate 410, and the falling materials can be always guided into the tabletting gap through the material guide plate 410 in the whole regulation.

It should be noted that: firstly, the quantity of the condensate water generated by the refrigeration equipment is larger than the output quantity of the condensate water; the method is favorable for ensuring good cooling effect on materials, a supporting rod 59 and a speed regulator for regulating the amount of condensed water produced by condensing equipment can be additionally arranged, and the supporting rod 59 is matched to drive the speed regulator to regulate rotation so as to regulate the production amount of condensed water in unit time; so that the pump body is matched with the output quantity in the unit time of the changed pump body, the sufficiency of condensed water can be ensured, excessive electric energy loss caused by excessive condensed water manufacturing quantity in the unit time of the condensing equipment is avoided, and the liquid outlet end of the pump body is connected with the two liquid inlet hard pipes 46 through the Y-shaped shunt pipes.

It should be noted that the present adjusting member also has some problems, for example, the compression spring 12 is more and more difficult to compress as the compression proceeds, (there is the same problem in the second embodiment that the elastic sealing gasket is more and more difficult to bulge upward, but the second embodiment adopts the elastic sealing gasket 21, the difficulty of deformation is easier than that of the compression spring 12, when the speed of the extruder pushing screw is slightly adjusted in a small range, the compression spring 12 and the elastic sealing gasket 21 do not need to be greatly deformed, the second embodiment and the third embodiment do not cause accumulation of materials on the tabletting rollers 41 (because of the influence of gravity and acceleration when the materials fall along a parabolic motion track, the impact force is exerted on the striker plate 410, the supporting plate 43 has a downward pressure effect on the compression spring 12, the compression spring 12 is compressed, the defect of the compression amount of the compression spring 12 can be overcome, or an upward force is exerted on the pull rope 20, the defect of the deformation amount of the elastic sealing gasket 21 can be overcome, and simultaneously, when the adjusting member and the gravity adjusting frame 5 are matched for use, the second embodiment and the third embodiment does not cause accumulation of materials on the tabletting rollers 41 (because of the impact force and the impact force of the second embodiment has a downward pressure effect on the compression spring 12, the compression force is exerted) and the upward, the defect of the compression amount of the elastic sealing gasket is overcome, or the defect of the elastic sealing gasket 21 is formed, the deformation due to the upward, when the deformation is caused by the deformation, when the impact force is caused by the impact force, and the impact force of the tension, when the compression force is caused by the impact force and the weight is caused by the impact force when the weight and the weight of the weight and the weight is larger, the phenomenon that the material on the tabletting rollers 41 is seriously accumulated and overflowed and dropped easily occurs because the tabletting speed is lower than the discharging speed.
