Specific embodiment
Below in conjunction with the embodiment of the present invention, the technical solution in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, those of ordinary skill in the art's all other embodiments obtained without making creative work, all
Belong to the scope of protection of the invention.
Embodiment：As shown in Figs. 1-5, a kind of shoe press loading device, between center sill 20 and boots plate 30, including
Presser unit and lift unit, the presser unit include hydraulic cylinder 10, and the hydraulic cylinder 10 includes being fixed on center sill 20
It cylinder body 11 and can be pressed on the boots plate 30 in the piston 12 of cylinder body activity, the piston 12, the lift unit packet
Include lift lever 13 and be sheathed on the elastic component 14 of lift lever, the lift lever 13 passes perpendicularly through cylinder body and piston, and with boots plate 30
It is fixedly connected, the elastic component 14 is fixed between cylinder body 11 and lift lever 13, is used to provide piston 12 and boots plate 30 is upward
Lifting force, the piston 12 connect by oil inlet pipe 16 with oil inlet, and the cylinder body 11 is fixed on center by connecting bolt
Boots plate is fixed in beam, 13 lower end of lift lever by positioning pin 15.The present invention is used in shoe press apparatus to press nips
Pressure is provided, mainly includes presser unit and lift unit, presser unit persistently gives boots plate downward pressure during the work time
Power so that boots roller and boots pressure two pairs of rollers coordinate and squeeze out the moisture in product, and lift unit is used for after presser unit pressure release to boots
Plate and presser unit carry out lifting restoring.The presser unit is hydraulic cylinder 10, and the hydraulic cylinder 10 includes cylinder body 11 and piston
12, the lift unit includes lift lever 13 and is sheathed on the elastic component 14 of lift lever, and cylinder body 11 passes through bolt and center sill 20
It is fixed together, lift lever 13 passes through cylinder body and piston, is fixedly connected between lift lever 13 and boots plate by positioning pin 15.
Because the lift unit and presser unit in the present invention are integrated into one, simple in structure, convenient to install and maintain, and using single
A elastic component is promoted, therefore single cylinder force is uniform, and oil cylinder piston sealing wear is small, extends its service life, together
When greatly provide the quality of product.
Wherein, the central axis of the 13 lower end edge cylinder body 11 of lift lever and piston 12 passes through hydraulic cylinder 10, the elasticity
14 lower end of part is abutted against in cylinder body 11, and upper end is fixed on lift lever 13.Elastic component 14 can be the recovery that spring is used for boots plate,
During off working state, the distance between the fixing sleeve 17 and cylinder body 11 be just elastic component in the raw under length,
During work, the hydraulic oil of certain pressure is continuously added by oil inlet so that piston 12 moves down, and boots plate 30 is driven to add downwards
Pressure achievees the purpose that two rollers squeeze, while spring is compressed；When being stopped, oil inlet stops oil inlet, and the pressure on piston is unloaded
It carries, since boots plate is heavier, piston and boots plate is promoted to by initial position by lift lever under the action of spring restoring force at this time,
So as to which two rollers be detached.14 upper end of elastic component is compressed by being sheathed on the fixing sleeve 17 of lift lever, and the fixing sleeve 17 is logical
Locking nut 18 is crossed to lock.The lower end of elastic component is abutted against into cylinder body, the other end is pre-tightened by fixing sleeve, and elastic component is compressed
Fixing sleeve is locked on cylinder body, then by locking nut 18 so that elastic component will not move up and down.
The operating process of the present invention：During work, external fueller is by oil inlet to being continuously added into liquid in hydraulic cylinder
Pressure oil, awarding 12 pressure of piston moves down it, and then drives the pressurization downwards of boots plate 30, reaches and matches boots roller and boots pressure two pairs of rollers
The purpose of the moisture in product is closed and squeezes out, lift lever moves downward in the process, therefore spring is constantly in compression shape
State；After the completion of work, oil inlet stops oil inlet, then 30 pressure release of piston 12 and boots plate, since boots plate itself is heavier, it is necessary to by outer
Power can just restPose, and lift lever 13 moves upwards under the restoring force effect of spring at this time, so as to piston and boots
Plate moves downward so that boots plate is detached 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
Subject to appended claims.
