The glue roller at the bottom of the pointed bottom bag, but the existing pointed bottom bag making and the following defects:

1. The existing drum is made of one-piece casting. Since such a drum needs to open a plurality of back cover grooves, the manufacturing cost is high, and the entire drum needs to be replaced when it is damaged and repaired. There is room for improvement.

2. The existing glue-holding assembly needs to put the glue into the glue-holding box, and then transport the glue to the gluing roller through the bottom glue roller, and then glue the pointed bottom bag, but the glue flow of this glue-holding assembly cannot be controlled and It is very troublesome to need to clean the plastic container frequently.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention lies in the deficiencies of the above-mentioned prior art,

Provides a bag making machine for pointed bottom bags, the glue holding device of the bag making machine can conveniently control the flow of glue, and the cleaning of glue is simple. It is more convenient to maintain and maintain, and the bag clamping mechanism is set in the drum wheel, so that the drum wheel can automatically clamp or release the pointed bottom bag when the drum rotates, so as to ensure the stability of the bottom sealing process of the pointed bottom bag.

In order to achieve the above purpose, the present invention provides the following technical solutions: a bag making machine for pointed bottom bags, comprising a frame, on which a paper tube unwinding part and an edge gluing part are sequentially arranged in the order of bag making , paper bag hemming parts, traction parts, bag cutting parts, bag pressing conveying parts, bag bottom gluing forming parts and paper bag collecting parts, the bag bottom gluing forming parts include drum transmission mechanism and gluing mechanism, the The drum transmission mechanism includes a drum and a driving assembly that drives the drum to rotate, and the gluing mechanism includes a gluing assembly for storing glue and a gluing roller for smearing the glue on the bottom of the pointed bottom bag in the drum, It is characterized in that: the drum wheel includes at least three drum wheel support plates and drum wheel side plates arranged on both sides of the drum wheel support plate to be detachably connected to the drum wheel support plate, and the drum wheel support plate is connected to the drum wheel support plate through a connecting piece. The drum wheel side plates on both sides are assembled into a drum wheel, and a bottom cover groove is provided between the two adjacent drum wheel support plates. The end of the drum corresponding to the bottom cover groove is provided with a bag clamping mechanism for clamping or opening the pointed bottom bag entering the bottom cover groove.

By adopting the above technical solution, the original integrally formed drum in the gluing and forming part on the bottom of the bag is changed to be composed of a plurality of drum support plates and two drum wheel side plates, so that the two ends of the drum support plate can pass through the screws and the drum wheel. The side plate of the wheel is fixedly connected to reduce the manufacturing difficulty and cost of the drum. Because the back cover groove on the drum is used to bond the bottom of the pointed bottom bag during use, the glue will inevitably block the back cover after a long time of use. The grooves make the drum lose the function of gluing the back cover. After the drum bracket is assembled with the drum side plate, when cleaning the glue, the drum bracket that needs to be replaced or cleaned can be removed separately, so that the drum can continue to be used. By setting the bag clamping mechanism in the bottom sealing groove, when the drum rotates, the bag clamping mechanism can be opened and closed in an orderly manner, which helps the transmission and bottom sealing of the pointed bottom bag, and ensures the stability of the bottom sealing process of the pointed bottom bag. The gluing surface is set lower than the drum surface on one side of the drum rotation direction. Since the gluing surface is lower than the surface of the drum, the gluing mechanism will make the bottom of the pointed bottom bag take the bottom cover groove as the folding line. Fold it slightly and put it into the bottom cover slot, so that this part of the folded pointed bottom bag is located between the bag clamping mechanism and the bottom cover groove, and the extended end is attached to the glue surface, which is convenient for bottom gluing the pointed bottom bag in the bottom cover groove. At the same time, the drum wheel rotates and cooperates with the bag clamping mechanism to swing in the bottom sealing groove to clamp the bottom of the pointed bottom bag in the bottom sealing groove to the bottom sealing.

The above-mentioned bag making machine for pointed bottom bags can be further set up as follows: the glue holding assembly includes a bottom glue rack plate, a glue holding plate and a bottom glue roller, the bottom glue rack plate is provided with a fixed support plate, and the fixed The pallet presses the glue holding plate on the surface of the fixed pallet through the pressing device, so that the glue holding plate can move on the surface of the fixed pallet. One end of the drum is provided with an arc-shaped contact surface for rotating and gluing the bottom rubber roller, and an adjusting device for adjusting the distance between the arc-shaped contact surface and the bottom rubber roller is provided between the fixed support plate and the plastic holding plate.
