Laminating conveyor elevating mechanism
Technical field
The present invention relates to a kind of laminating conveyor of insulation board production line, particularly a kind of lift of laminating conveyor
Structure.
Background technology
Laminating conveyor in existing polyurethane thermal insulation board production line balance, its elevating mechanism lifts for hydraulic jack, lacks
Put and be:1st, the design formula of hydraulic jack is unreasonable, it is impossible to obtain larger safety coefficient, thus the structure of hydraulic jack and
Strength design theory is also more delayed, causes its kinetic characteristic by certain limitation;2nd, hydraulic jack stressing conditions are estimated not
Such as, still there are unsafe conditions, in-oil cylinder rod fracture unavoidably in foot;3rd, hydraulic jack is compared with cylinder, easy oil leakage, work
It is a no small consumption to make medium hydraulic oil;4th, hydraulic jack lifting precision is low.
The content of the invention
Goal of the invention:In view of the above-mentioned problems, it is an object of the invention to provide one kind is safe, lifting precision is high, structure
The elevating mechanism of reliable laminating conveyor.
Technical scheme:A kind of laminating conveyor elevating mechanism, including guide pillar, enter power worm screw, internal carry wrom tooth wheel and spiral shell
Transmission fuselage, the servomotor of line copper piece, the lower end of the power of the entering worm screw are connected with the transmission fuselage, the power of the entering worm screw
Upper end and the upper strata of laminating conveyor are fixed, the guide column sleeve mounted in it is described enter power worm screw outside, the servomotor with it is described
The connection of transmission fuselage come drive it is described enter power worm screw moved up and down along the guide pillar.
The elevating mechanism is respectively mounted a set of in laminating conveyor both sides.
The transmission fuselage, the servomotor are fixed relative to the lower floor of laminating conveyor.
The principle of the invention is:Elevating mechanism is started with servomotor, makes the wrom tooth wheel and screw thread copper piece of transmission fuselage interior
Rotation, promotes to drive the upper strata rise and fall campaign of laminating conveyor into power worm screw.
Beneficial effect:Compared with prior art, it is an advantage of the invention that:With Serve Motor Control, stable transmission, precision
High, reliability is high, and elevating mechanism compact conformation, small volume, lightweight, power source are extensive, noise is small, easy for installation, use spirit
Living, service life is long;Elevating mechanism has lifting, landing function, with separate unit or can be applied in combination;Can be by certain procedures exactly
Control adjustment lifting or the height of landing, design specification is from 0.5 ton to 100 tons, and dynamic endurance is from 0.3 ton to 26 tons, lifting
Speed is up to 3600mm/min.
Brief description of the drawings
Accompanying drawing is schematic structural view of the invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification for planting the equivalent form of value falls within the application appended claims limited range.
As shown in drawings, a kind of laminating conveyor elevating mechanism, including guide pillar 1, enter power worm screw 2, internal carry wrom tooth wheel
And transmission fuselage 3, the servomotor 4 of screw thread copper piece.
The lower end for entering power worm screw 2 is connected with transmission fuselage 3, enters the upper end of power worm screw 2 with being conveyed by upper box 5 with lamination
The upper strata 6 of machine is fixed.Guide pillar 1 is sleeved on outside power worm screw 2, is entered power worm screw 2 and is moved along the vertical direction inside guide pillar 1.Watch
Take motor 4 to be connected with transmission fuselage 3, transmission fuselage 3 is fixed by the lower floor 8 of lower box 7 and laminating conveyor.
Servomotor 4 starts, and makes the wrom tooth wheel inside transmission fuselage 3 and the rotation of screw thread copper piece, promotes to drive into power worm screw 2
The upper strata 6 of upper box 5 and laminating conveyor carries out rising or falling motion relative to the lower floor 8 of laminating conveyor.
In order that the elevating movement of laminating conveyor is more stable, can be by elevating mechanism of the present invention in laminating conveyor both sides
It is respectively mounted a set of, separate unit as needed or is applied in combination, accurately controls adjustable height.
