Problems solved by technology

[0009] The purpose of the present invention is to overcome the defects of the negative pressure device existing in the existing packaging machine when the bag is opened and opened, which has a large working load and high energy consumption, and the bag opening action cannot be carried out smoothly and the bag burst due to insufficient delivery of the prefabricated bag. The invention provides a bag stretching method for a packaging machine. Using the bag stretching method can reduce the work load of the negative pressure device and reduce energy consumption, and the prefabricated bag can be accurately transported to the bag opening and stretching station, avoiding the failure of the prefabricated bag The bag opening action caused by conveying in place cannot be carried out smoothly and the phenomenon of bag bursting occurs

Embodiment 1

[0053] This embodiment provides a bag stretching method for a packaging machine, which is characterized in that it includes the steps of bag receiving, translation, bag opening, bag stretching and translation reset,

[0054] The bag receiving means that the bag receiving plate 501 is connected to the prefabricated bag at the bag receiving station 505, and is fixed by the adsorption hole 503 on the bag receiving plate 501 corresponding to the opening of the prefabricated bag;

[0055] The translation means that the bag receiving plate 501 is translated from the bag receiving station 505 to the bag opening and opening station 506 under the drive of the translation mechanism. Translate from bag receiving station 505 to bag opening station 506;

[0056] The bag opening means that the suction cup 6 absorbs the upper side of the bag mouth at the bag opening station 506, and cooperates with the adsorption hole 503 on the lower side of the bag mouth to open the bag mouth;

[0057] Th...

Embodiment 2

[0061] This embodiment provides a bag receiving and conveying mechanism 5 of a packaging machine, through the function of the bag receiving and conveying mechanism 5, the bag receiving and conveying action of prefabricated bags is realized, and the specific structure is as follows:

[0062] The bag receiving conveying mechanism 5 includes a bag receiving plate 501 and a translation mechanism that enables the bag receiving plate 501 to reciprocate between the bag receiving station 505 and the bag opening station. There are adsorption holes 503;

[0063] There is only one position on the side of the bag receiving plate 501 corresponding to the opening of the prefabricated bag with an adsorption hole 503 .

[0064] The adsorption hole 503 can only absorb the lower side of the mouth of the prefabricated bag.

[0065] The translation mechanism includes a power source and a guide 502 , the pocket plate 501 is movably mounted on the guide 502 , and the power source drives the pocket...

Embodiment 3

[0068] This embodiment provides a bag receiving and conveying mechanism 5 of a packaging machine, through the function of the bag receiving and conveying mechanism 5, the bag receiving and conveying action of prefabricated bags is realized, and the specific structure is as follows:

[0069] The bag receiving conveying mechanism 5 includes a bag receiving plate 501 and a translation mechanism that enables the bag receiving plate 501 to reciprocate between the bag receiving station 505 and the bag opening station. There are adsorption holes 503;

[0070] The translation mechanism includes a power source and a guide 502 , the pocket plate 501 is movably mounted on the guide 502 , and the power source drives the pocket plate 501 to move on the guide 502 .

[0071] The upper surface of the guide 502 is provided with a bar-shaped groove, and the bar-shaped groove is arranged along the length direction of the guide 502. The lower surface of the pocket plate 501 is provided with a bar...

Abstract

The invention discloses a bag expanding method for a packaging machine, and belongs to the field of packaging machines. The bag expanding method comprises the steps of bag receiving, translation, bag opening, bag expanding and translation reset, wherein in the bag receiving process, a prefabricated bag is received by a bag bearing plate at a bag receiving station; in the translation process, the bag bearing plate is driven by a translation mechanism to perform translational motion and to reach a bag opening and expanding station; in the bag opening process, the upper side of the bag mouth of the prefabricated bag is adsorbed by a suction cup at the bag opening and expanding station, and the bag mouth is opened under the combined action of the suction cup and an absorbing hole in the lower side of the bag mouth; in the bag expanding process, a circular-arc bag expanding claw extends into the bag mouth, and then the left and right sides of the bag mouth are expanded; and in the translation reset process, the bag bearing plate performs translational motion and reaches the bag receiving station after being separated from the prefabricated bag. By adoption of the bag expanding method, the workload of a negative pressure device and the energy consumption can be reduced. Besides, the prefabricated bag can be correctly conveyed to the bag opening and expanding station, so that the phenomena of the unsmooth bag expanding action and bag explosion caused by conveying of the prefabricated bag to an improper station can be avoided.
