The vacuum sealer disclosed with reference to the accompanying drawing to the utility model is illustrated, as shown in Fig. 2 comprising machine Shell 1, the casing 1 include cuboid 11 and rectangular prismatoid 12, and the top plate of the two is hinged by hinge 13, the right-angled trapezium Panel corresponding to the right angle waist of body 12 is hatch frame, and the top surface of the rectangular prismatoid 12 is bottom, and bottom surface is upper Bottom is safeguarded so that the rectangular prismatoid 12 can overturn opening with the component to its inside.

Also, as shown in Fig. 2, the casing 1 by sliding rack 5 be slidably disposed in it is a pair of extend longitudinally lead On rail 6, the guide rail 6 is set on a portal frame 30, and the portal frame 30 is set on the pedestal with one group of universal wheel, institute Stating the connection of sliding rack 5 drives it along the lifting device 7 that the guide rail 6 is gone up and down, and the lifting device 7 can be various feasible The equipment or structure of linear motion, such as cylinder or electric cylinders or similar structure etc. can be generated, details are not described herein, preferably For cylinder, and gag lever post 40 is additionally provided on the telescopic shaft of the cylinder.

As shown in Fig. 2, pipeline (not shown) connection vacuum evacuation device is provided on the casing 1 (in figure Be not shown) flat air exhaust nozzle 2 and a pair of of connection power supply circuit and cooperating the first fire-bar 3, the second fire-bar 4, such as Shown in attached drawing 3, the flat air exhaust nozzle 2 includes at least a plate 21 and encloses the arc of a flat air flue with the plate 21 Plate 22, the radian of the arc panel 22 are no more than 2, so as to facilitate it is subsequent by gas nozzle from the first fire-bar 3, second plus It is extracted out between hot item 4, meanwhile, and it is true to guarantee to take out to reduce the gap between sack that flat air exhaust nozzle 2 can be made flat as far as possible Empty effect realizes effective unification of the two.

In addition, the top of the plate 21 and arc panel 22 also has integrated molding as shown in attached drawing 3, attached drawing 4 And top opening is circular changeover portion 23, the changeover portion 23 is connected with quick union 24, and the flat air exhaust nozzle 2 is logical It crosses fastener to be fixed on a pedestal 50, in the power device that the connection of pedestal 50 drives it back and forth to go up and down along longitudinal direction (in figure not Show), the power device equally can the various devices that can generate linear motion or structure, thus the flat pumping Mouth 2 is able to carry out longitudinal movement and projects over outside the casing 1, and specifically, the bottom plate of the rectangular prismatoid 12 is arranged There is the notch for the stretching of flat air exhaust nozzle 2.

Under first state, the lower end of the flat air exhaust nozzle 2 is located under first fire-bar 3, the second fire-bar 4 Side, first fire-bar 3, the second fire-bar 4 keep gap；Under second state, the lower end of the flat air exhaust nozzle 2 is located at institute State the top of fire-bar 2,3, the opposite end face fitting of first fire-bar 3, the second fire-bar 4.

Wherein, as shown in Fig. 2,3 position of the first fire-bar is fixed on the bottom of the cuboid 11 and is protruded from The outer end face 111 of cuboid 11, the second fire-bar 4 can be mobile relative to the first fire-bar 3, are set on a rotating turret 8, described The end of two supporting plates 81 of rotating turret 8 is pivotally connected at the outer end face 111 of the cuboid 11 and is located at the right angle ladder In body, offered on the bottom plate of the rectangular prismatoid with two matched notches of the supporting plate 81 for the rotating turret 8 Rotation, two supporting plates 81 of the rotating turret 8 are also pivotally connected the driving means 9 for driving the rotating turret 8 to rotate respectively, described Driving means can be two cylinders, their piston rod is pivotally connected two supporting plates 81, can be with thus when piston rod stretches out Rotate two supporting plates 81 around the rotation axis of they and cuboid 11, thus make the first fire-bar 3, the second fire-bar 4 open or It is close to.

In addition, being carried out in order to when heated to the PE bag portion point of first fire-bar 3,4 upper area of the second fire-bar Fixed limit has position to be located at the first fixed fire-bar 3 and push away on the outer end face of the cuboid 11 as shown in Fig. 5 Send the gag lever post 60 between device 9, the both ends of the gag lever post 60 extend to outside the both ends of first fire-bar 3 and itself and institute The outer end face for stating the first fire-bar 3 is concordant, also, leads to 60 deformed damaged of gag lever post, the gag lever post in order to avoid contacting firmly 60 are fixed at the outer end face of the cuboid by two elastic slices 70, so as to real by the deformability of the elastic slice 70 Now float.

Meanwhile as shown in Fig. 2, the vacuum sealer further includes being located at first fire-bar 3, the second fire-bar 4 The pipeline 10 of lower section, the pipeline 10 can be known various pipelines, such as belt line, roller line, herein be existing There is technology, repeat no more, is provided with positioning mechanism 20 between the pipeline 10 and the first fire-bar 3, the second fire-bar 4, The positioning mechanism 20 includes being located at 10 two sides of pipeline and opposite push plate 201, and two push plates 201 can be opposite It moves and backwards to movement, i.e., they is separately connected the translation structure for driving them to translate, such as cylinder, to work as their opposite fortune When moving to gap minimum, the article between them can be made to position.

The vacuum evacuation device, power supply circuit, various cylinders, electric cylinders or electrical components are all connected with control device (in figure not Show), such as PLC system, it is set at the outer end plate (the corresponding panel of oblique angle waist) of the rectangular prismatoid, so as to benefit It with its own structure, is operated convenient for staff, and combines various sensors and control button, so as to after actuation, The automatic operation for carrying out Vacuum Package.

When the vacuum sealer work of this programme, process is as follows:

S1, the pipeline 10 convey the lower section that first fire-bar 3, the second fire-bar 4 are moved to sealed product, Then, two startings of push plate 201 are moved toward one another and will be positioned to sealed product, this stage is about 1.5S with the time.

S2, then, the casing 1 are displaced downwardly to first fire-bar 3, the second fire-bar 4 positioned at described to sealed product Top below two sides, 3 distance of the first fire-bar to the distance at the top of sealed product in 30mm or so, meanwhile, it is described flat Air exhaust nozzle 2 is displaced downwardly to described in sealed product, this step used time about 1S.

S3, moveable second fire-bar 4 are rotated to the first fire-bar 3 of the fixation, and the two cooperation will be produced wait seal The mouth area of product clamps, and the used time of this step is about in 1S.

S4, by the vacuum degree to be evacuated to requirement in sealed product, the pumpdown time exists for the vacuum evacuation device starting Between 6-7 seconds.

S5, the flat air exhaust nozzle 2 are moved up and are extracted out to sealed product, then, the heating of the first fire-bar 3, second After item 4 is heated to set temperature, setting time, cooling a period of time, the first fire-bar 3, the second fire-bar 4 unclamp, and realize heat Envelope waits next task finally, the product after the heat-sealing is conveyed blanking, and each member reset by the pipeline 10.

Wherein, after study personnel it is a large amount of experimental studies have found that, when heat-sealing, the temperature of heat-sealing is at 220-240 DEG C, heat-sealing The integrality that is sealed in 6-7S of time and fastness it is best, the preferably time is 6.5S, to both be not in two side areas Each layer bonding loosely the problem of, the problem of fracture is melted in intermediate region transition, control further cooling time will not occur In 2S or so, fire-bar unclamps time about 1S, and the time-consuming control of entire heat-seal stage is in 4.5S or so.

Still there are many embodiment, all technologies formed using equivalents or equivalent transformation for the utility model Scheme is all fallen within the protection scope of the utility model.
