Description

Continous way boxed food controlled atmosphere fresh-keeping packing machine

Technical field

The utility model relates to a kind of boxed food package packing machine, especially a kind of boxed food controlled atmosphere fresh-keeping packing machine.

Background technology

Along with the quickening of people's rhythm of life, boxed food progresses in people's life, but the fresh-keeping subject matter that becomes boxed food.At first generally by in box, vacuumizing, promptly so-called vacuum packaging, vacuum-packed for packed food still can, but make the box distortion easily or squeeze broken for the negative pressure that boxed food exists.Afterwards, by in box, passing through ventilation, promptly air is taken out, charge into unreactable gass such as nitrogen, carbon dioxide, obtained comparatively obvious effects, as State Intellectual Property Office's on January 2nd, 2002 disclosed " the gas replacement structure of boxed food wrapping machine " patent (patent No.: 01217028, publication number: CN2468905Y).This patent has mainly been done improvement to air-exchanging structure, and by the bevelled jet orifice, a part of gas is injected into stream sealing film back reflection to packing box central authorities, and another part flows through from the gap at heat-sealing film and packing box top, to improve displacement efficiency.The deficiency that this class patent exists is: the ventilation packing can not realize continuity, and air exchanging rate has influenced the work efficiency of wrapping machine slowly.

Summary of the invention

The problem that the utility model quasi-solution is determined provides a kind of boxed food controlled atmosphere fresh-keeping packing machine of continous way.

For achieving the above object, the utility model has adopted following technical scheme: a kind of continous way boxed food controlled atmosphere fresh-keeping packing machine, it comprises mode structure, following mode structure, air-exchanging structure and connecting gear control setup, the described mode structure of going up comprises upper molded plate, heat seal die, with heat seal die bonded assembly cutting tool and upper cylinder, described heat seal die is connected with the axle of upper cylinder, described upper molded plate is connected with the axle elasticity of upper cylinder, it is characterized in that described mode structure down comprises actuating device and a plurality of diaphragm capsule, described a plurality of diaphragm capsule chain type connects, and the bottom of each diaphragm capsule is provided with to inflate to buckle with exhaust and buckles; Described air-exchanging structure comprises with the inflation of diaphragm capsule buckles the pneumatic head that is complementary, the exhaust head that is complementary with the exhaust button, the little cylinder that is connected with pneumatic head, exhaust head respectively, and with the storage tank of pneumatic head plumbing connection; Described control setup respectively with upper cylinder, little cylinder and actuating device) be electrically connected.

Above-mentioned actuating device is a stepping motor.

It is to connect by spring that the above-mentioned upper molded plate of going up mode structure is connected with the elasticity of the axle of upper cylinder.

Owing to adopted technique scheme, when diaphragm capsule moves to the patrix correspondence position by actuating device, because the effect of upper cylinder moves down heat seal die, because will moving to and inflate on pneumatic head and the exhaust head, the effect of little cylinder detains and arranges tight-lipped position of joining simultaneously, diaphragm capsule is put on the air and exhaust, after inflation and exhaust are finished heat seal die is sealed the box body in the diaphragm capsule, cutting heat-sealing film by cutting tool on the one hand afterwards, on the other hand, fill exhaust and stop, pneumatic head and exhaust head move down.Finished packaging process like this one time, the running by actuating device enters next packaging process again, is noted that the moving down of running, heat seal die of actuating device here, moves all the control by control setup on pneumatic head and the exhaust head.By the technical solution of the utility model, make the boxed food wrapping machine realize continuous running, improved the work efficiency of wrapping machine.

The specific embodiment

As shown in Figure 1, continous way boxed food controlled atmosphere fresh-keeping packing machine of the present utility model comprises mode structure, following mode structure, air-exchanging structure and connecting gear control setup.

The described mode structure of going up comprises upper molded plate 18, heat seal die 1, is fixed on cutting tool 2, upper cylinder 3 and push rod 17 on the heat seal die 1, and upper cylinder 3 is by push rod 17 and 1 scalable connection of heat seal die.

The size of described heat seal die 1 and food box kissing.Upper molded plate 19 links to each other with cylinder 3 elasticity, and described elasticity links to each other and can connect by spring 19.

Described counterdie comprises actuating device 11 and a plurality of diaphragm capsule 5, and actuating device 11 is preferably stepping motor, a plurality of diaphragm capsule 5 chain types connect, and chain type bonded assembly diaphragm capsule 5 can move by actuating device 11.The size of described diaphragm capsule 5 and clay model pressing plate 18 are complementary, and make upper molded plate 18 energy seal cover caps on diaphragm capsule 5.The bottom of diaphragm capsule 5 be provided with fill the head buckle 6 and exhaust buckle 7.

Described air-exchanging structure comprises pneumatic head 8, file leader 9, stingy cylinder 10 and storage tank 12, described pneumatic head 8 and exhaust head 9 respectively with stingy 10 scalable connections of cylinder.Described pneumatic head 8 is provided with admission port 13 and exhausr port 14 (referring to Fig. 2), the admission port 13 and gaholder 12 plumbing connections of pneumatic head 8, exhausr port 14 ends of pneumatic head 8 and the inflation fastening leakproof fit on the diaphragm capsule 5 can seal the exhausr port of pneumatic head 8 and fall in the inflation button; Also do not have admission port 15 and exhausr port 16 (referring to Fig. 3) on the described exhaust head 9, admission port 15 ends of exhaust head 9 and the exhaust fastening leakproof fit on the diaphragm capsule 5 can seal the admission port 15 of exhaust head 9 and fall in the exhaust button.

Described control setup 4 is electrically connected with upper cylinder 3, stingy cylinder 10 and actuating device 11 respectively.

The utility model is to turn round in the following manner: when wrapping machine starts, make a diaphragm capsule 5 that has packing box move to the patrix correspondence position by actuating device 11, because the effect of upper cylinder moves down upper molded plate 18 and heat seal die 1, upper molded plate 18 moves down into when covering diaphragm capsule 5 positions, stop to move down, because the effect of spring 19, making upper cylinder 3 can continue to drive heat seal die 1 moves down, at this moment because the effect of stingy cylinder 10, make move on pneumatic head 8 and the exhaust head 9 with the inflation of diaphragm capsule 5 buckle 6 and exhaust buckle 7 and closely cooperate, to inflation and exhaust in the diaphragm capsule 5, heat seal die 1 is sealed food box in the diaphragm capsule 5 by the box film, afterwards on the one hand by the unnecessary box film of cutting tool cutting; On the other hand, fill exhaust and stop, pneumatic head moves down.Finished packaging process like this one time, the diaphragm capsule 5 by chain type does not stop to move the packing of can taking a breath continuously.

Here be noted that the moving down of running, upper molded plate 18 and heat seal die 1 of actuating device 11, move on pneumatic head 8 and the exhaust head 9 all and finish by control setup 4 controls.

Also need illustrate a bit, pneumatic head 8 gas filed unlatchings and stop and the control by control setup 4 to realize, as the electromagnetic valve of a controlled device 4 controls is installed, also can be by the mechanical control of elastic construction, as structure to the pneumatic head of automobile tyre inflation, inflation when pneumatic head pushes with the inflation button, inflation stops when loosening.Because these all belong to technique known, no longer do detailed description here.
