The lift lever 13 is fixedly connected with boots plate 30, and the elastic component 14 is arranged between lift lever and center sill 20, and for that will live
Plug and boots plate 30 are lifted up, and the hydraulic cylinder 10 is equipped with three pistons 12 altogether along the length direction of boots plate, wherein middle work
Fill in for Large Piston, the piston at both ends is small-sized piston.The present invention is used to provide pressure to press nips in shoe press apparatus,
Mainly include hydraulic cylinder and lift unit, hydraulic cylinder persistently gives boots plate downward pressure during the work time so that boots roller and
Boots pressure two pairs of rollers coordinate and squeeze out the moisture in product, lift unit be used for after presser unit pressure release to boots plate and presser unit into
Row lifting restoring.The hydraulic cylinder 10 includes piston seat 11 and piston 12, is used between the piston and piston seat equipped with oil pocket 18
In storage hydraulic oil, the lift unit is respectively arranged on the both sides of hydraulic cylinder, including lift lever 13 and the bullet for being sheathed on lift lever
Property part 14, piston seat 11 are fixed together by bolt and center sill 20, and the lower end of lift lever 13 is fixedly connected with boots plate.
Piston in the present invention is square piston, hence in so that pressure area cross-directional line pressure is uniform, that is, ensure that the compression of product is uniform, has
Improve to effect the quality of product；Three groups of pistons are equipped with the present invention, pass through oil by the way of subregion is controllable in operating process
Three groups of piston oil pockets are pressurizeed on road, and piston moves down after being pressurized and awards boots plate pressure, simple in structure, easy to operate；This
The guide rod being equipped with invention can correct the deviation of boots plate automatically, avoid the scene adjustment manually taken time and effort,
So as to shorten the cycle of installation, improve work efficiency.
Wherein, 13 lower end of lift lever is fixedly connected with boots plate 30, and 14 lower end of elastic component is fixed with center sill 20 to be connected
Connect, upper end is fixed on lift lever 13.Elastic component can be the recovery that spring is used for boots plate, in off working state, the elasticity
Part in the raw under, during work, the hydraulic oil of certain pressure is continuously added into by oil inlet so that piston 12 is to moving down
It is dynamic, drive boots plate 30 to pressurize downwards, achieve the purpose that two rollers extrude, while spring is compressed；When being stopped, oil inlet stops
Oil inlet, the discharge degree on piston, since boots plate is heavier, at this time under the action of spring restoring force by lift lever by piston and
Boots plate is promoted to initial position, so that two rollers be separated.14 upper end of elastic component is by being sheathed on the fixation casing pressure of lift lever
Tightly, the fixing sleeve is locked by locking nut.The lower end of elastic component is abutted against in center sill, upper end is pre- by fixing sleeve
Tightly, and by elastic component it is pressed in center sill, then fixing sleeve is locked by locking nut so that elastic component will not occurs up and down

Pilot hole is formed after connecing, the guide rod 15 is placed in pilot hole.The guide rod 15 being equipped with can carry out certainly the deviation of boots plate
It is dynamic to correct, the scene adjustment manually taken time and effort is avoided, so as to shorten the cycle of installation, is improved work efficiency.It is described
Upper half bore 17 and lower half bore 31 are all semicircle, and the guide rod 15 is cylinder, is used between the piston 12 and boots plate 30
Buckle-type connects, and can relatively rotate between the two.Therefore, boots plate can be adjusted the angle freely, can compensate deviation automatically, be become
Shape amount is small, so as to extend the service life of boots plate and improve the compatible degree of pressure area.
The operating process of the present invention：During work, exterior fueller is continued by oil inlet into the oil pocket of hydraulic cylinder
Hydraulic oil is added, awarding 12 pressure of piston moves down it, and then drives boots plate 30 to pressurize downwards, reaches boots roller and boots pressure
Two pairs of rollers coordinate and squeeze out the purpose of the moisture in product, and lift lever 13 moves downward in the process, therefore spring is located always
In compressive state；After the completion of work, oil inlet stops oil inlet, then 30 pressure release of piston 12 and boots plate, must since boots plate itself is heavier
It must can just restPose by external force, lift lever 13 moves upwards under the restoring force effect of spring at this time, so as to drive
Piston and boots plate move downward so that boots plate departs from pressure area, returns to original state.
It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the premise, may be used also
To make several modifications and improvements, these belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with
