Although said structure can realize the platen and revert action of paper-weight more satisfactoryly, there is more serious safety to lack
Fall into, i.e., paper-weight, which rests on a high position, is realized by the pulling of spring assembly, and generally only sets one in the prior art
Spring, and on the one hand spring easily reduces elasticity in long-term use because stretching repeatedly, cause it to reset inaccurate, on the other hand
Easily it is damaged, once there is the non-normal working situation such as spring breakage, then paper-weight, which will lose, upward returns a power
And directly fall on paper feeding platform so that the operating area of paper-weight bottom is abnormally dangerous, has a strong impact on personal safety.
Utility model content
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide security performance height, used
The paper-weight spring return function device of long lifespan.
To achieve the above object, the utility model provides following technical scheme：Paper-weight spring return function device, there is machine
Frame, the frame are provided with paper feeding platform, and paper-weight is provided with above the paper feeding platform, and the both ends of the paper-weight connect respectively
Connecting rod is connected to, a pair of levers are provided with the frame and below the paper feeding platform, institute is hinged in the middle part of the lever
State in frame, the frame is provided with hydraulic cylinder, and described lever one end and the lower end of the connecting rod are hinged, the other end with it is described
The piston rod of hydraulic cylinder is hinged, it is characterised in that is provided with a pair of springs, the spring one in the frame above the paper-weight
End is connected with screw mandrel, and the other end is arranged on spring mounting seat, and the screw mandrel is arranged in the frame, the spring mounting seat
On be connected with chain, for the chain around being connected on sprocket wheel, the sprocket wheel is in methods, rack on the paper-weight and coaxially connected
There is sector gear, driving chain is connected with the sector gear, the end of the driving chain is connected on the paper-weight.
A pair of spring connecting poles are respectively equipped with the nut of the screw mandrel and the spring mounting seat, every spring connects
Corresponding to being connected on the spring connecting pole.
The connecting rod and the lever are symmetrical set.
The beneficial effects of the utility model are that, by using the return form of dual spring, the technology for serving dual fail-safe is imitated
Fruit, solve a conventional spring breakage and result in the safety problem that paper-weight drops；Meanwhile using sector gear and sprocket wheel
Combining form, the amplification of several times can be carried out to the active force of spring, it is only necessary to which spring carries out less telescopic variation just can be real
The active force of existing size as in the past, conventional spring is overcome because what significantly telescopic band repeatedly came loses, is fully prolonged
The service life of spring is grown.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is structural representation of the present utility model.
Embodiment
Accompanying drawing illustrates the technical solution of the utility model and embodiment, is further described in fact in conjunction with accompanying drawing below
Apply each relevant details of example.
As shown in figure 1, paper-weight spring return function device, has frame 1, the frame 1 is provided with paper feeding platform 2, in institute
State the top of paper feeding platform 2 and be provided with paper-weight 3, the both ends of the paper-weight 3 are connected to connecting rod 4, in the frame 1 and in
The lower section of paper feeding platform 2 is provided with a pair of levers 5, and the middle part of the lever 5 is hinged in the frame 1, the connecting rod 4 and institute
State lever 5 to be symmetrical set, to realize the technique effect of steady mobile paper-weight 3, and keep the lower surface of paper-weight 3 with sending
The upper surface of paper platform 2 flushes, more accurately to be flattened to the paper on paper feeding platform 2.The lower section of lever 5 is provided with liquid
Cylinder pressure 6, described one end of lever 5 and the lower end of the connecting rod 4 are hinged, and the piston rod of the other end and the hydraulic cylinder 6 is hinged.
When being pushed up on the piston rod of hydraulic cylinder 6, the lever 5 at left and right sides of it will be driven under its support motion, the drivening rod 4 of lever 5
Move, connecting rod 4 drives paper-weight 3 to push, and then realizes the pressing to the paper on paper feeding platform 2.
The top of paper-weight 3 is provided with a pair of springs 13, and described one end of spring 13 is installed on screw mandrel 14, and the other end is arranged on
On spring mounting seat 11, specific connected mode is as follows：It is respectively equipped with the nut and the spring mounting seat 11 of the screw mandrel 14
A pair of spring connecting poles 12, every spring 13 are connected on the corresponding spring connecting pole 12.The screw mandrel 14 is installed
In the frame 1, the length of spring 14 can be adjusted by adjusting screw mandrel 14, to adjust its spring force.In the present embodiment,
As a result of a pair of springs 13, even if a wherein spring 13 connects in long-term use of favorite outer fracture, also another spring
Then paper-weight 3, prevent it from falling, solve a conventional spring 13 fracture and result in the safety problem that paper-weight 3 drops, rise
The technique effect of dual fail-safe is arrived, and the spring force of two springs 13 is more preferable so that the lifting of paper-weight 3 is more stable；It is described
Chain 10 is connected with spring mounting seat 11, the chain 10 is around being connected on sprocket wheel 9, and the sprocket wheel 9 is on the paper-weight 3
In methods, rack 1 and sector gear 7 is coaxially connected with, driving chain 8 is connected with the sector gear 7, the driving chain 8
End is connected on the paper-weight 3.Using the combining form of sector gear 7 and sprocket wheel 9, the active force of spring 13 can be entered
The amplification of line number times, it is only necessary to spring 13, which carries out less telescopic variation, just can realize the active force of size as in the past, gram
Conventional spring 13 has been taken because what significantly telescopic band repeatedly came loses, has fully extended the service life of spring 13.Work as liquid
When the dynamic paper-weight 3 of heading tape pushes on the piston rod of cylinder pressure 6, paper-weight 3 will drive driving chain 8 to move down, and then drive sector
Wheel 7 and sprocket wheel 9 are rotated counterclockwise, while chain 10 is tightened up with sprocket wheel 9, and pull two springs 13 to extend；When paper-weight 3 terminates
When pushing work, the piston rod retraction of hydraulic cylinder 6, the lever 5 at left and right sides of it is driven to move, the drivening rod 4 of lever 5 moves up,
Connecting rod 4 drives paper-weight 3 to move up, and at the same time, because spring 13 has restoring force, pulls on chain 10 and moves, and then drives
Sprocket wheel 9 and sector gear 7 turn round, and driving chain 8 also moves up with sector gear 7, realize that the steady of paper-weight 3 moves up.
To sum up, this paper-weight spring return function equipment safety performance height, service life length.
