Environmental protection type veneer board pressing device
Wood processing technique field is the utility model is related to, is specifically a kind of environmental protection type veneer board pressing device.
Glued board is one of furniture common used material, is one of three big plate of wood-based plate, also for aircraft, ship, train, vapour
Car, building and packing case etc. act on material.One group of veneer is usually formed by the orthogonal assembly gluing of adjacent layer grain direction, usually
Its dash board and inner plating are symmetrically arranged at the both sides of central core or plate core.It is crisscross by grain direction with the veneer after gluing
The slab being made into, suppresses under conditions of being heated or not heated and forms.The number of plies is generally odd number, and minority also has even number.Side in length and breadth
To physics, engineering properties difference it is smaller.It is common to have three-ply board, five-ply board etc..
Need that the multilayer laminate for being stained with adhesive is used hydraulic pressure control with pressing device in the process of multi-plywood
The prepressing device compacting of system is integral, but existing pressing device is overweight using being pressurized in precompressed in the middle part of glued board, causes
The plank of surrounding opens, and causes precompressed to fail, it is impossible to preferable to complete precompressed work.Cause the reduction of glued board qualification rate, cause
Waste of material.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of environmental protection type veneer board pressing device.
The utility model is achieved through the following technical solutions：A kind of environmental protection type veneer board pressing device, including base, it is described
Base is equipped with workbench；Support column is fixed with the workbench；Top plate is fixed with the support column；The top plate
Under be fixed with pressing oil cylinder, pressing oil cylinder has force fit plate；The pressing oil cylinder lower end is fixed with turntable；Under the turntable
It is hinged with four connecting rods；Four connecting rod lower ends have been respectively articulated with sliding block；Be fixed with the upper force fit plate two it is intersecting
Slide, the crosspoint of two slides is immediately below pressing oil cylinder；Sliding block described in each two is slidably mounted on a slide；
Support plate is fixed with the both ends of the slide, screw rod is installed in two support plates；The hand of spiral phase at both ends on the screw rod
Instead, the sliding block is connected through a screw thread with opposite screw rod.
It is further：The upper force fit plate is rectangular；The slide is separately fixed on the diagonal of force fit plate.
Described screw rod one end is fixed with handle.
Buffer board is placed with the workbench；Lower force fit plate is placed with the buffer board.
The sliding block is in inverted " convex " type, and slider bottom is inserted into slide, and sliding block bottom is not contacted with slide bottom.
The both ends of the slide are each to fix two slide bars；The support plate is slidably mounted on slide bar；The slide bar upper end
It is fixed with cap body；Spring is cased with the slide bar below the support plate.
Compared with prior art, the beneficial effects of the utility model are：Upper force fit plate is connected by adjustable connecting rod so that
Oil cylinder is pressed to the pressure dissipation of upper force fit plate, is more uniformly stressed；Also, according to the big of different glued boards to be processed
It is small, the stress point of upper force fit plate can be adjusted, then there is preferably pressing effect；The utility model entirety pressing machine
Structure is simple, and bonding processes simple and fast, practicality is preferable, thus is adapted to promote and apply.

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of environmental protection type veneer board pressing device, including base 1, base 1 are equipped with workbench 2；Work
Make to be fixed with support column 3 on platform 2；Top plate 4 is fixed with support column 3；Pressing oil cylinder 5 is fixed with top plate 4.Press oil cylinder 5
Lower end is fixed with turntable 6, and four connecting rods 7 are hinged with turntable 6；Four 7 lower ends of connecting rod have been respectively articulated with sliding block 8；Sliding block 8 is installed
In lower force fit plate 15.
In conjunction with shown in Fig. 2, upper force fit plate 10 is rectangular；Two slides 9 are separately fixed at the diagonal of force fit plate 10
On, the crosspoint of two slides 9 is immediately below pressing oil cylinder 5.The both ends of slide 9 are each to fix two slide bar 9-1；Support plate 11 is slided
It is dynamic to be installed on slide bar 9-1；Slide bar 9-1 upper ends are fixed with cap body 9-2；Spring is cased with slide bar 9-1 below support plate 11
9-3.This structure ensures can there is certain amount of exercise up and down on slide bar 9-1.
Each two sliding block 8 is slidably mounted on a slide 9；Sliding block 8 is connected through a screw thread with opposite screw rod 12, screw rod
The hand of spiral at both ends is opposite on 12.This structure ensure that two sliding blocks 8 are symmetrical all the time.Sliding block 8 is in inverted " convex " type, sliding block
8 bottoms are inserted into slide 9, and 8 bottom of sliding block is not contacted with 9 bottom of slide.In this way, when connecting rod 7 pushes sliding block 8, screw rod 12
Move downward, so that the both sides of sliding block 8 are pressed on slide 9, protection screw rod 12 is from very big downward pressure.
12 one end of screw rod is fixed with handle 13, easy to adjusting screw rod 12.
Buffer board 14 is placed with workbench 2；Lower force fit plate 15 is placed with buffer board 14.Glued board is placed on pushing
Plywood 15, buffer board 14 buffers the stress of glued board, in order to avoid receive larger impact and damage.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
