Description

Packagine machine's opening bag mechanism

Technical Field

The utility model relates to an improvement invention of bag making equipment, in particular to a sealing mechanism of a bag making machine.

Background

At present, the bag opening position of the bag body of the horizontal packaging machine is only opened, the tail part of the bag body is still in a closed state, particularly, the side surfaces of the bag body are an M-shaped bag body and a self-standing bag, the bottom of the bag body is not easy to open, namely, the upper bag surface and the lower bag surface of the tail part of the bag body are still attached together, and the bag body is not completely opened, so that the space in the bag is insufficient. When reinforced, the material pushes into to be obstructed, if the hardness of material is higher, then can extrude into the bag in, nevertheless also cause the material impaired easily, if the material is comparatively soft, pushes by force and then causes the material to warp easily, damages even. Therefore, the existing bag opening mechanism needs to be improved.

Disclosure of Invention

In view of the technical problem that exists among the background art, the utility model aims at providing a can be with the bag mechanism of opening that the bag body was opened completely.

In order to solve the technical problem, the utility model discloses a following technical scheme: this kind of packagine machine's opening bag mechanism, its characterized in that: comprises that

The bag opening part comprises an upper material sucking part and a lower material sucking part, and the upper material sucking part can lift up and down;

and the gas charging part comprises a sealing plate, the sealing plate is in sealing fit with the bag opening, and the sealing plate is provided with a gas inlet which is connected with a gas source.

The upper suction piece adsorbs the upper bag face of the bag body, the lower suction piece adsorbs the lower bag face of the bag body, the upper suction piece moves upwards to open the bag mouth, the sealing plate blocks the bag mouth to seal the bag mouth and inflates the bag through the air inlet, the tail of the bag body is propped open after the gas is filled into the bag body, the bag body is completely opened, the storage space in the bag is sufficient, the material can smoothly enter the bag from the bag mouth, the material cannot be squeezed, and therefore the material cannot be damaged and is kept complete, and the packaging quality is improved.

Furthermore, the sealing plate is connected with a power part which drives the sealing plate to move relative to the bag opening of the bag body. The power part drives the sealing plate to move relative to the bag opening, when the bag is inflated, the sealing plate moves towards the bag opening, the bag opening is sealed by the sealing plate and the bag opening, and after the bag is opened, the sealing plate is far away from the bag opening.

Fig. 2 is a schematic view of the utility model after the bag body is completely opened.

Detailed Description

The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings. The bag opening mechanism of the packaging machine comprises a bag opening part and an inflating part, wherein the bag opening part comprises an upper material sucking part 1 and a lower material sucking part 2, the upper material sucking part can lift up and down, and the lifting of the upper material sucking part can adopt a cylinder, a cam mechanism, a connecting rod mechanism, a lead screw mechanism, a transmission belt and the like, and the methods are more and are not listed one by one; the inflatable unit is including closing plate 3, closing plate and the sealed cooperation of sack, be equipped with air inlet 4 on the closing plate, the air inlet is connected with the air supply, its meaning of sealed complex is closing plate and sack laminating, and the closing plate is plugged up the sack, forms certain sealed effect between the two, does not indicate absolute sealed, because of machining error, the bag body yielding simultaneously, even closing plate 3 also can't reach absolute sealed with the sack laminating. The sealing plate is connected with a power part which drives the sealing plate to move relative to the bag opening of the bag body 7, the power part can adopt an air cylinder or a motor combined with a screw rod mechanism and the like, the power part adopts the air cylinder in the figure, and the air cylinder 5 drives the sealing plate to move back and forth relative to the bag body.

The bag body 7 is placed on the material table 6, the upper suction piece 1 adsorbs the upper bag face of the bag body, the lower suction piece 2 adsorbs the lower bag face of the bag body, the upper suction piece moves upwards, the upper bag face moves upwards along with the upper bag face, the upper bag face is separated from the lower bag face, the bag mouth is opened at the moment, then the air cylinder 5 drives the sealing plate 3 to move towards the bag mouth and be attached to the bag mouth, the bag mouth is blocked by the sealing plate, an air source is filled into the bag through the air inlet, the tail of the bag body is propped open through air, the bag body is completely opened, the sealing plate 3 retreats and resets, after the bag body is completely opened, the storage space in the bag is sufficient, the material can smoothly enter the bag from the bag mouth, the material cannot be squeezed, and therefore the material cannot be damaged, the bag is kept complete, and the packaging quality is improved.
