Embodiment
Describe embodiment of the present utility model in detail below with reference to specific embodiment, whereby to the utility model such as
What application technology means solves technical problem, and the implementation process for reaching technique effect can fully understand and implement according to this.
Embodiment
With reference to figure 2, Fig. 3, a kind of dual chamber list lid vacuum packing machine, including frame 1 and upper lid 2, the upper lower surface of lid 2
Provided with two sealing joint strips be arrangeding in parallel 21, two vacuum chambers be arrangeding in parallel 11, the upper lid 2 are opened up in the frame 1
It is provided between frame 1 and is used to make the upper circulation of lid 2 be covered in the upper end of two vacuum chamber 11 and form the swing mechanism 3 of annular seal space, institute
Stating swing mechanism 3 includes four connecting rods 31 and four gas springs 32, and each connecting rod 31 is symmetrically disposed in the side of lid 2 simultaneously two-by-two
It is parallel to each other, the both ends of connecting rod 31 are rotatably connected in lid 2 and frame 1 respectively, the both ends point of each gas spring 32
It is not rotatably connected on the middle part of each connecting rod 31 and frame 1, each gas spring 32 is installed on the outside of each connecting rod 31, this
So that each connecting rod 31 is swung in the presence of the elastic force of gas spring 32 using the fulcrum in frame 1 as the center of circle, and gas spring 32 is also
Also swung with the swing of connecting rod 31 using the fulcrum in frame 1 as the center of circle, and in the present embodiment, on connecting rod 31 and frame 1
Tie point, the tie point in gas spring 32 and frame 1, both is distributed along same vertical curve.
In the present embodiment, the side wall of each vacuum chamber 11 is provided with two heating tubes 12, positioned at corresponding to the lower section of heating tube 12
Air bag 13 is provided with, each heating tube 12 is connected to transformer 14, vavuum pump 15, each vacuum chamber 11 are provided with the frame 1
Solenoid valve block 16 is connected to, the vavuum pump 15 forms gas and be connected with each solenoid valve block 16, each vacuum chamber 11.
In the present embodiment, one end of connecting rod 31 is located at the medium position of the side of vacuum chamber 11, and the other end is connected to the side of lid 2
Close to edge, during operation, four connecting rods 31, which remain, in face is parallel to each other so that upper lid 2 remains horizontal, under upper lid 2
When falling to be fitted in vacuum chamber 11, acted on down by the gravity of upper lid 2 and by vavuum pump 15 and cause the interior generation negative pressure of vacuum chamber 11,
Overcome the elastic force of gas spring 32, lid 2 is fitted in the upper end of vacuum chamber 11, and now start air bag 13, heating tube 12 and become
Depressor 14, and then complete the heat-sealing operation of wherein one side vacuum chamber 11；Then air loopback is carried out to the vacuum chamber 11, makes this true
When the air pressure inside of empty room 11 reaches balance with outside, in the presence of the elastic force of gas spring 32, upper lid 2 is naturally steady to be risen, and is returned to
Initial position.
It is pointed out that the gas spring 32 used in the present embodiment can be replaced cylinder or hydraulic cylinder, will be by artificial half certainly
Dynamic production replaces with electrically automatic production, further mitigates labor strength, raises labour efficiency.
Again as shown in figure 4, used by for the present embodiment sealing joint strip 21 cross-sectional view, due to sealing joint strip
21 overall close heating tubes 12 are installed, therefore need good heat resistance, and also to have stronger ability of anti-deformation, and this reality
It is in inverted ladder structure of right angle that it is overall, which to apply sealing joint strip 21 used in example, it include be located inside " L " shape cushion block 211 with
And the elastomer block 212 outside the cushion block 211 is coated on, the one end being in contact with the side wall of vacuum chamber 11 is trapezoidal oblique
Side, and round-corner transition is sentenced, so being rotated in upper lid 2 can be more flexible when whereabouts is covered in vacuum chamber 11, is not in card
Dead phenomenon, the elastomer block 212 described in the present embodiment are formed by polyurethane foam, have good heatproof, a pull resistance, and internal
Cushion block 211 then make it that sealing joint strip 21 is overall not easy to break, improves service life.
The utility model realizes that single upper lid is applied on two vacuum chambers by setting swing mechanism, during plant running
Upper lid is promoted by gas spring by four connecting rods and realizes that reciprocating swing, worker only need to adjust the side of lid between two vacuum chambers
To the cycle operation that two vacuum chambers can be achieved, upper lid has four uniform support force effects from the beginning to the end, is not in
The upper lid problem on deformation as caused by unbalance stress, ensure that the overall mechanical stability of device, reduces failure rate of machinery；Together
When gas spring can be replaced with to cylinder or oil cylinder, by setting the stroke of cylinder or oil cylinder, electrification automatically controls connecting rod
Swaying direction, realize whole-course automation produce.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
