Referring to fig. 4 and 5, in a normal state, one end of a film to be cut is conveyed from the upper side of an upper conveying roller 21 to the upper side of a cutting table 3 and is conveyed out from between an upper pressing roller 32 and a lower pressing roller 33, the other film is conveyed from the upper side of a lower conveying roller 22 and passes through the lower side of the cutting table 3 and is conveyed out from between the upper pressing roller 32 and the lower pressing roller 33, when the film conveyed from the upper conveying roller 21 passes through the cutting table 3, after a cutting groove is cut on the upper side of the film through a cutter 1 disc, a reciprocating mechanism drives the cutting table 3 to move towards the direction of the upper conveying roller 21, the upper pressing roller 32, the lower pressing roller 33 and a glue spraying pipe 34 can be simultaneously driven to move towards the direction of the upper conveying roller 21 through the cutting table 3, meanwhile, the glue spraying pipe 34 is opened, the discharge roller 23 stops rotating along with the slippage of the cutting table 3, the two, the upper press roll 32 and the lower press roll 33 compress the two films close to each other after glue spraying, so that the two films are compounded into a bag film, then, the reciprocating mechanism pushes the cutting table 3 to reset, simultaneously, the film to be cut and the uncut film are continuously conveyed, the steps are repeated to realize the forming and grooving of the bag film, because the strength of the film is reduced after grooving, but in the compounding process of the bag film, the cut film is kept still and is not pulled, after the grooved film is compounded with another film, the compounded bag film is driven to be conveyed by the discharging roller 23, so that the grooved film can not be broken and the like in the compounding process, ensures the compounding of the bag film, and in addition, the adopted heating device can heat the upper pressing roller 32 and the lower pressing roller 33, thereby increasing the heat of the upper press roll 32 and the lower press roll 33 and further enabling the two films to be rapidly compounded.
The implementation principle of embodiment 3 of the application is as follows: after the film is cut, the transmission of the film is stopped, another film which is not cut into the groove is attached to the film which is cut into the groove, the compounding of the two films is completed, the strength of the film which is provided with the groove can be prevented from being reduced after the groove is cut, the film which is cut into the groove is prevented from being torn in the compounding process, and the compounding stability of the bag film is further ensured.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
