[0017] The utility model will be further described below in combination with specific embodiments. It should be understood that the following embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.

[0018] Embodiment 1

[0020] As Figs. 1-3As shown, a negative pressure film receiving device of a multi-column packaging machine comprises a film receiving mechanism 100 and a conveying positioning structure 200.

[0021] The film receiving mechanism 100 comprises a vacuum generator 110, a film receiving plate 120, a negative pressure switch 130, a positive pressure air 140, an air suction groove 150, an air pipe 160, an air pipe joint 170, a first film pressing magnet 181, a second film pressing magnet 182, a third film pressing magnet 183, and a fourth film pressing magnet 184.

[0022] The conveying positioning structure 200 comprises a left side plate 210, a right side plate 220, a pay-off roller 230, an upper film conveying roller 240, a lower film conveying roller 250, a first reversing film conveying roller 260, and a second reversing film conveying roller 270.

[0023] The principle of the utility model is that when the device is started, the pay-off roller 230 starts to rotate under the power drive and releases the packaging film.

[0024] When the film splicing operation is needed, the first film pressing magnet 181, the second film pressing magnet 182, the third film pressing magnet 183 and the fourth film pressing magnet 184 are lowered to tightly press the packaging film. Then, a tool (such as a utility knife) is used to cut the packaging film along the center line of the film splicing plate 120. After cutting, the first film pressing magnet 181 and the second film pressing magnet 182 are opened, the old roll of film is lifted out, the new roll of film is placed in the corresponding position, the new roll of film is threaded to the film splicing platform and pulled to be stacked at the lower end of the film splicing plate 120. The film pressing magnets that are opened before are lowered again, and then the tool is used to cut along the center line again, and the excess waste edge is removed. At this time, the negative pressure switch 130 is opened, the positive pressure gas 140 enters the front end of the negative pressure switch 130, and the vacuum generator 110 connected at the rear end is triggered to work. The vacuum generator 110 draws air from the air suction groove 150 of the film splicing plate 120 through the air pipe 160 and the air pipe connector 170, so that a negative pressure environment is formed in the air suction groove 150. Under the action of negative pressure, the film splicing plate 120 adsorbs the packaging film (the new film and the old film abutting portion), at this time, the new and old roll of film can be spliced according to the cutting center line by using the adhesive tape, and the film splicing operation is completed.

[0025] In summary, the utility model discloses a roll-off roller and a film feeding roller, film unwinding and film feeding, and the side plate plays a guiding role, ensuring the tension and flatness of the film, providing a stable basis for film splicing, avoiding the influence of poor film state and position deviation on film splicing. When splicing the film, the film pressing magnet is used to fix the position of the film, thereby improving the accuracy of the process during cutting, changing the roll of film and cutting again to remove the waste edge, and making the whole operation process smoother and improving the efficiency of film splicing. Before splicing the new and old roll of film, the negative pressure switch is opened, the positive pressure gas triggers the vacuum generator to work, air is drawn from the air suction groove through the air pipe and the connector to form negative pressure, and the adhesive tape is spliced after the film splicing plate adsorbs the abutting portion, replacing manual operation and further improving the efficiency of film splicing.

[0026] The specific embodiments of the utility model have been described above, but the utility model is not limited thereto, and various changes can be made without departing from the purpose of the utility model.
