Background

The main bag making process of the packaging bag comprises the following steps: raw material film blowing, film printing, multilayer film compounding, composite film curing, heat sealing bag making, cold press molding, slitting and the like. Wherein, the heat seal bag making is called sealing for short, and the sealing is mainly realized by heating to ensure that the material at the position to be sealed reaches a viscous flow state and pressurizing to seal the material; the seal directly determines the tightness of the package, which is very important for food products to ensure that they do not deteriorate during storage.

In the prior art, a packaging bag heat sealing machine comprises a rack, wherein a workbench is arranged on the rack, and a melting and pressing plate is connected above the workbench in a sliding manner; when the sealing device is used, a packaging bag to be sealed is placed on the workbench, then the melting pressing plate is slid, the packaging bag is heated and fused, and then the packaging bag is pressurized, so that the sealing position is formed.

Although the prior art can seal the packaging bag, there are still some points to be improved: when the packaging bag is used for a long time, the position of the melting and pressing plate is easy to deviate, so that the heat sealing position is not accurate enough, and the sealing property and the attractiveness of the packaging bag are affected.

Disclosure of Invention

The invention aims to provide a bag making device for processing food packaging bags, which solves the problem that a heat sealing position of a packaging bag heat sealing machine in the prior art is inaccurate due to the fact that a melting and pressing plate deviates.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

Compared with the prior art, the invention has the following principle and beneficial effects: automatic conveying is carried out on the packaging bags through the conveying unit, manual feeding and discharging are not needed, and bag making efficiency is improved. Utilize the air feed case to provide the air to the vortex tube inlet end, air is partly heated in the vortex tube, enters into the passageway in the backup pad from the hot gas end, and another part is cooled, enters into the cold wind incasement from the cold air end to utilize the vortex tube can obtain hot air and cold air simultaneously, need not additionally to use heater and refrigerator, reduced the emission of discarded object, still saved the resource.

After hot air enters the channel, the hot air enters the air guide box and is exhausted from the air exhaust port, so that continuous air flow is formed in the air guide box, the air flow serves as driving force to give impact force to the turbine to drive the turbine to rotate, the turbine drives the first gear to rotate when rotating, the first gear intermittently drives the first rack to move, the first rack drives the supporting plate, the supporting plate enables the telescopic rod to stretch and retract, and the supporting plate reciprocates under the combined action of the first rack and the telescopic rod, so that the pressing plate is driven to carry out heat sealing treatment and pressure adjustment on the packaging bag; when the hot air heats the channel, the channel is close to the pressing plate, so that the pressing plate can be heated, the packaging bag is heated and fused when the pressing plate is contacted with the packaging bag, and the fused part is sealed and formed by pressure. The telescopic rod is arranged, so that the supporting plate is limited in the moving process, and the heat sealing position is prevented from being inaccurate due to position deviation; meanwhile, heated air is used as driving force, the effect of waste gas utilization is achieved, reciprocating movement of the pressing plate can be achieved without additionally arranging a power source, and the effects of energy conservation and emission reduction are achieved.

After cold air enters the cold air box, the cold air is blown to the packaging bag through the air vents, and the packaging bag after heat sealing is cooled, so that the packaging bag is formed, and the deformation of the sealing position of the packaging bag caused by stretching in the subsequent processing process is reduced. The packaging bag is automatically cut through the cutting unit, and the packaging bag is cooled and formed, so that the stretching of the packaging bag by the cutting stress can be reduced during cutting, the possibility of the deformation of the cut of the packaging bag is reduced, and the quality of the packaging bag is improved.

When the backup pad removed to the wrapping bag, will drive the removal of interior loop bar, made first elastic component warp, because interior loop bar one end is in outer loop bar, its slip receives the restriction of outer loop bar, consequently can play limiting displacement to the backup pad at gliding in-process to prevent that the clamp plate from taking place the offset, thereby promote the accuracy of sealing.

Furthermore, the cutting unit comprises a second rack which is connected to the rack in a sliding mode, a second elastic part is connected between one end of the second rack and the rack, a base is fixedly connected to the other end of the second rack, a cutter is arranged on the base, and a second sector gear which is meshed with the second rack is coaxially connected with the turbine.

The rotation of the turbine drives the second gear to rotate, the second gear drives the second rack to intermittently move, and the second rack drives the cutter to move so as to automatically cut the packaging bag; the automatic cutting of the packaging bag can be realized without arranging an additional power source, and the energy-saving effect is achieved.

Further, be equipped with buffer gear on the base, buffer gear includes the outer pole of rigid coupling on the base, and sliding connection has interior pole in the outer pole, is connected with the third elastic component between interior pole one end and the outer pole, and the interior pole other end is used for contacting with the wrapping bag.

During cutting, the inner rod compresses and fixes two sides of the cutting part of the packaging bag, the cutter continues to move along with the base to cut the packaging bag, the outer rod continues to move along with the base in the process and slides along the inner rod, and the third elastic piece deforms; by arranging the buffer mechanism with the structure that the outer rod is sleeved with the inner rod, on one hand, the packaging bag to be cut can be fixed through the inner rod, the packaging bag is prevented from being positioned in the cutting process, and therefore the cutting accuracy is improved; on the other hand can also be injectd through the mutual position of outer pole and interior pole, plays limiting displacement to the removal of cutter, prevents the cutter skew to further improve the effect of cutting.

Further, the buffer layer is wrapped at the end, in contact with the packaging bag, of the inner rod.

The buffer layer is arranged, so that the inner rod is prevented from being directly contacted with the packaging bag, and indentation is left on the packaging bag in the pressing and fixing process.

Further, the vent hole is perpendicular setting with the wrapping bag.

So as to shorten the time of the cold air reaching the packaging bag and improve the cooling efficiency and effect.
