[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] See Figures 1 to 4 , a dynamic adjustment mechanism for the bellows of a paper bag machine, having: a frame; a lower conveying mechanism 1 installed on the frame, and the lower conveying mechanism 1 can convey the paper tube of the handbag; an upper conveying mechanism 2 that can support the upper end of the paper tube of the handbag; a hemming mechanism provided on both sides of the lower conveying mechanism 1, and the hemming mechanism can squeeze both sides of the paper tube of the handbag. The lower conveying mechanism 1 functions to convey the paper bag, the upper conveying mechanism 2 supports the upper end of the paper tube of the handbag and spreads the paper tube, and the hemming mechanism squeezes both sides of the paper tube of the handbag to form a bend.

[0032] A height adjustment mechanism 22 is provided on the upper conveying mechanism 2, and the height adjustment mechanism 22 can adjust the height of the upper conveying mechanism 2. By adjusting the height of the upper conveying mechanism 2 through the height adjustment mechanism 22, the height of the paper tube can be adjusted, forming paper tubes of different heights to meet the usage requirements of paper bags of different specifications.

[0033] The upper conveying mechanism 2 has a support bar 21, and the support bar 21 can support the paper tube of the handbag. The support bar 21 is installed on the height adjustment mechanism 22. The support bar 21 can support the upper end of the paper tube of the handbag and spread the paper tube.

[0034] The height adjustment mechanism 22 includes: an upper support rod 221 and a lower support rod 222. The upper support rod 221 is installed on the support bar 21, and the lower support rod 222 is installed on the frame; a guide rail 223 is provided on the upper support rod 221 and the lower support rod 222; a slider 224 is slidably arranged on the guide rail 223; a fork arm mechanism connects the upper support rod 221 and the lower support rod 222; the fork arm mechanism includes a first fork arm and a second fork arm. The upper end of the first fork arm is hinged to the upper support rod 221, and the lower end of the first fork arm is hinged to the slider 224 on the lower support rod 222; the upper end of the first fork arm is hinged to the slider 224 on the upper support rod 221, and the lower end of the first fork arm is hinged to the lower support rod 222. By rotating the lead screw 225, the slider 224 is driven to slide on the guide rail 223, so that the first fork arm and the second fork arm swing, changing the angle between the first fork arm and the second fork arm, thereby lifting the upper support rod 221 to achieve the purpose of changing the height. Thus, the height of the paper tube can be adjusted to form paper tubes of different heights to meet the usage requirements of paper bags of different specifications.

[0035] The first fork arm and the second fork arm are hinged near the middle part, and the first fork arm and the second fork arm are connected to each other, which can improve the stability of the first fork arm and the second fork arm.

[0037] The hemming mechanism 4 has a hemming bracket 41, a support rod 44 and a pressing disc 45. The support rod 44 is installed on the hemming bracket 41, and the pressing disc 45 is rotatably installed on the support rod 44; the pressing disc 45 can squeeze both sides of the paper tube of the handbag. The hemming mechanism 4 can also adopt other types of squeezing and hemming mechanisms 4 commonly used in the art. The pressing disc 45 can also rotate driven by a driving mechanism. The pressing discs 45 on both sides squeeze the two sides of the paper bag tube inward, and then cooperate with the lower conveying mechanism 11 and the upper conveying mechanism 22 to squeeze the paper tube of the handbag into a flat shape, forming an "M" shape on both sides of the paper tube of the handbag.
