Referring to fig. 1 to 3, the method for pressing bubbles in a cartridge includes the following steps:

s10, sleeving the barrel box on the inner mold 22;

it should be noted that the side walls of the barrel box include two opposite first side walls and two opposite second side walls, and the form in which the existing barrel box fixing inner mold 22 is embedded is changed into a barrel box sleeve, so that the reverse process of the barrel box is not required to be increased, and the labor cost is reduced.

S20, moving the inner mold 22 and the barrel box to a bubble pressing station 202, and pressing two first side walls and/or two second side walls of the barrel box to be tightly attached to the inner mold 22 for bubble pressing;

it should be noted that, according to different requirements of the same type of cassette, some of them only need to press a group of side walls of the barrel cassette for bubbling; there is a need to bubble the two sets of side walls without limiting the order of the two first side walls and the two second side walls.

S30, moving the inner mold 22 and the barrel box to the blanking station 203, and separating the inner mold 22 and the barrel box.

Based on the above embodiment, step S20 further includes the following steps:

and S11, adhering the pre-glued box bottom paper to the box bottom wall of the barrel box while carrying out primary bubble pressing.

Different box types are different in processing sequence during processing, and after the facial tissue is pasted with the hawk and is folded, the barrel-shaped structure is formed, two ends of the barrel-shaped structure are opened, the bottom facial tissue of the box needs to be attached independently after the bottom hawk of the box is installed, for example, when the bottom facial tissue of the box does not exist, and during primary bubbling, the bottom facial tissue of the box with pre-glued is adhered to the bottom hawk of the box. Because the bottom of barrel box remains towards the outside all the time in station conversion process, can integrate the process of pasting box bottom facial tissue to pressing the bubble process in, the mechanism of pasting box bottom facial tissue can with press bubble mechanical synchronization action, save time, improve the holistic machining efficiency of barrel box. It should be noted that the order of the step and the step S201 is not limited, and may be performed synchronously.

Based on the above embodiment, the following steps are further included after step S202:

and S21, pressing the bottom wall of the barrel box to be tightly attached to the inner die 22 so as to press the bottom paper of the box for bubbling.

After the box bottom surface paper is bonded with the box bottom gray board, the pressing bubble work is still needed, the process and the secondary pressing bubble are integrated in one production beat, the processes can be reduced, the production beat is saved, and the overall processing efficiency of the barrel box is improved. It should be noted that the order of the step and the step S203 is not limited, and may be performed synchronously.

The above process can be used for processing the barrel bottom and barrel box supplies after the barrel body is manufactured, and can also be used for processing another box type, please refer to fig. 3, and the barrel bottom of the box type needs to be additionally attached with a layer of barrel bottom surface paper to cover the barrel bottom. When the wine barrel box is processed, the front barrel body forming process is unchanged, barrel box incoming materials of barrel bottom ash plates of the exposed portions of the barrel bottoms are formed, after the rear section is connected to the bubble pressing process, in the first step of bubble pressing process, the barrel bottoms of the barrel box incoming materials face upwards, at the moment, the barrel bottoms are in an advantageous state of being easy to process, and in the process, barrel bottom surface paper after glue coating is added to the barrel bottoms to package the exposed portions of the barrel bottoms.
