Description
Technical field: the part of appliance that the invention belongs to laminating conveyor in rigid foam continuous sandwich plate production line.Particularly a kind of Multi-cylinder synchronization apparatus of laminating conveyor.
Background technology: laminating conveyor is that one is hard plate material for the production of upper and lower surface layer, centre is flame-retardant polyurethane, polyisocyanurate, phenolic foam sandwich sheet, rigid foam continuous sandwich plate production line special equipment.Multi-cylinder synchronization apparatus, guarantees the device of several working cylinder synchronous operations of all steady liftings of upper laminating machine that make laminating conveyor.Existing laminating conveyor Multi-cylinder synchronization apparatus is all the synchronization loop devices that adopt multi-stage diffluence valve or flow divider-combiner to be combined into.There is in actual use following deficiency in this synchronization loop device of prior art:
1, can only guarantee that the speed that piston in each working cylinder rises or decline is synchronous, and the physical location that piston in unrealized each working cylinder rises or declines is synchronous.Its reason is each single multi-stage diffluence valve or the flow divider-combiner of composition synchronization loop device, first, exists standard to allow in manufacture process, actual each different tolerance grade; Secondly, it is poor that the sealing property of each single multi-stage diffluence valve or flow divider-combiner also certainly exists; In addition, each single multi-stage diffluence valve or flow divider-combiner, in the time being used in combination in pairs in synchronization loop, certainly existing and amplify step by step shunting oil mass error.Above-mentioned reason has caused this synchronization loop device of prior art, in the time of actual motion, there is the shunting difference of can not ignore, therefore the oily flow of pressure that shunting enters each working cylinder also certainly exists larger difference, its actual result be cause multi-cylinder piston to rise or the speed that declines synchronous, and piston in each working cylinder rises or the physical location that declines asynchronous.This has just caused and has relied on upper laminating machine that several working cylinder synchronous operations could the lifting stability decreases in uphill process or decline process, if things go on like this, must shorten the service life of laminating conveyor.
2, can only apply in working cylinder synchronous operation that sum is even number, be that the synchronous operation of working cylinder of odd number is just helpless to sum.Its reason is the composition multi-stage diffluence valve of synchronization loop device or flow divider-combiner number while being even number, could form effective device loop of moving.This is restricted with regard to the design length that causes laminating conveyor, cannot meet user's actual needs.
As can be seen here, study and design a kind of physical location that can realize the piston rising in each working cylinder or decline synchronous, the Multi-cylinder synchronization apparatus of the unrestricted laminating conveyor of working cylinder number is necessary.
Summary of the invention: it is not enough the object of the invention is to overcome prior art, studies and designs a kind of physical location that can realize the piston rising in each working cylinder or decline synchronous, the Multi-cylinder synchronization apparatus of the unrestricted laminating conveyor of working cylinder number.
The technical scheme that realizes the object of the invention is: a kind of Multi-cylinder synchronization apparatus of laminating conveyor, comprise main oil pump, drive the main motor of main oil pump, supporting main oil pump is arranged at the total check valve on working connection, main overflow valve, pressure display table, main solenoid valve, be communicated in several working cylinders of main solenoid valve through main hydraulic control one-way valve, working cylinder piston lower inner cavity on the working connection before secondary check valve, secondary overflow valve, secondary magnetic valve are communicated in total check valve, is characterized in that main solenoid valve is communicated in main oil cylinder piston lower inner cavity through synchronous hydraulic control one-way valve by auxiliary oil circuit; Every working cylinder piston cavity of resorption is communicated with a corresponding synchronized cylinder by synchronous oil circuit; Arranged radially is around master cylinder centered by master cylinder for every synchronized cylinder, and the piston rod end of every synchronized cylinder and main oil cylinder piston boom end are linked on the circular connecting plate of same by securing member.
Object of the present invention can also adopt following further technical measures to realize:
In several described working cylinders, the number of elements of working cylinder is the 4-28 concrete number of elements of choosing of merely hitting.The technique effect of this design is the requirement according to user, the needs of laminating conveyor overall design, the number of elements of working cylinder not only can be chosen to be 4,6,8,10,12,14,16,18,20,22,24,26,28, also can be chosen to be 5,7,9,11,13,15,17,19,21,23,25,27.
Described several working cylinders that are communicated in main solenoid valve through main hydraulic control one-way valve refer to: be communicated in inner chamber on the piston of several working cylinders of main solenoid valve.Described synchronous oil circuit is communicated with in a corresponding synchronized cylinder, and synchronous oil circuit had both been communicated in inner chamber on the piston of synchronized cylinder, is also communicated in the piston lower inner cavity of synchronized cylinder.The tailpiece of the piston rod of several described working cylinders is all fixed on the upper laminating machine body of laminating conveyor.The technique effect of above-mentioned three designs is in the course of the work, when hydraulic oil is inputed to master cylinder by main oil pump, promotes connecting plate and drives synchronized cylinder to promote, and now the piston of synchronized cylinder, by the defeated oil working cylinder that is pressed onto, promotes the piston rod of working cylinder.Because the tailpiece of the piston rod of working cylinder is fixed on upper laminating machine body, thereby complete the ascending motion of laminating machine, in the time of master cylinder off-load, hydraulic oil enters working cylinder epicoele, working cylinder is declined, hydraulic oil in working cylinder cavity of resorption is back to synchronized cylinder and drives connecting plate and the decline of main oil cylinder piston bar, returns to original position.
Described arranged radially centered by master cylinder is in master cylinder synchronized cylinder around, is to adopt only singly, or 2 or 3 synchronized cylinders superpose up and down and share same piston rod, and its end and main oil cylinder piston boom end are linked in same circle connecting plate by securing member.The technique effect of this design is under the constant prerequisite of result of use, makes as much as possible compact conformation between master cylinder, synchronized cylinder, connecting plate, reduces manufacturing cost.
The Multi-cylinder synchronization apparatus of the laminating conveyor that the invention process obtains, through on probation, has compared with prior art shown following beneficial effect:
1, realize the physical location that piston in each working cylinder rises or decline synchronous.Adopt each synchronized cylinder piston rod to be fixed as one through the piston rod of connecting plate and master cylinder, force to drive the piston corresponding to several synchronized cylinders of several working cylinders to rise with a master cylinder, because every working cylinder piston cavity of resorption is communicated with a corresponding synchronized cylinder by synchronous oil circuit, and the piston of every synchronized cylinder rises and will through synchronous oil circuit, hydraulic oil be pressed into the piston lower inner cavity of a corresponding synchronized cylinder, force the piston physical location of synchronized cylinder synchronously to rise, again because the tailpiece of the piston rod of several described working cylinders is all fixed on the upper laminating machine body of laminating conveyor, thereby obtain the effect that upper laminating machine body rises thereupon.On completing after the ascending motion of laminating machine, in the time of master cylinder off-load, hydraulic oil enters inner chamber on each working cylinder piston through synchronous hydraulic control one-way valve-main hydraulic control one-way valve, working cylinder piston is declined, the hydraulic oil of working cylinder piston lower inner cavity is back to inner chamber on synchronized cylinder piston, so force working cylinder piston to decline, the band plate that is dynamically connected forces to drive main oil cylinder piston bar to decline, and returns to the home position before rising.Whole Multi-cylinder synchronization apparatus does not adopt multi-stage diffluence valve or the flow divider-combiner of prior art, also just avoided because of the piston physical location of the tolerance grade difference of each multi-stage diffluence valve or flow divider-combiner, each synchronized cylinder that sealing property difference causes asynchronous, further avoid the unstable equipment damage causing of upper laminating machine uphill process, compared with prior art also just played the beneficial effect that extends the service life of laminating conveyor.
2, working cylinder number is not because the operation of Multi-cylinder synchronization apparatus is restricted.The Multi-cylinder synchronization apparatus that prior art adopts multi-stage diffluence valve or flow divider-combiner to be combined into, because the operation of flow divider or flow divider-combiner must be to meet the condition that working cylinder number is even number, is that the synchronous operation of working cylinder of odd number is just helpless to sum.And the present invention adopt every synchronized cylinder centered by master cylinder arranged radially around master cylinder, the piston rod end of every synchronized cylinder and main oil cylinder piston boom end are linked in the technical scheme on the circular connecting plate of same by securing member, in enforcement, are obviously the problems of even number without consideration working cylinder number.As long as user has demand, according to the needs of laminating conveyor overall design, can select 4-28 including odd number arbitrary concrete cylinder number of merely hitting; In addition between synchronized cylinder and working cylinder, be through synchronizeing oil circuit connection, as long as user has demand, according to the needs of laminating conveyor overall design, can selecting the high-pressure oil pipe of Len req as synchronous oil circuit.This just makes to adopt the laminating conveyor of the Multi-cylinder synchronization apparatus that the invention process obtains to meet better user's needs, has improved the market competitiveness of complete machine, more easily obtains coml success than the laminating conveyor that still adopts prior art Multi-cylinder synchronization apparatus.
