Description

Handle strip feeding mechanism and handle strip feeding method Technical Field The invention belongs to the technical field of packaging bag manufacturing, and particularly relates to a handle strip feeding mechanism and a handle strip feeding method. Background The bag making machine is special equipment for producing plastic, non-woven fabric, paper and other material packing bags, and is mainly applied to the packing requirement of clothing, food, gift and other industries. For example, the production of shopping bags, serving bags, food bags, and the like can be performed by a bag making machine. Generally, in the process of producing a packaging bag by a bag making machine, a handle, namely a handle, needs to be arranged at the edge of a substitute port of the packaging bag, and when the bag making machine processes the handle on a bag blank for the packaging bag, the bag making machine generally needs to convey a handle strip material roll wound on a material discharging frame to a handle forming mechanism by gradually expanding the handle strip material roll, and then cut the whole handle strip in sequence by the handle forming mechanism and then install the cut handle strip on a bag body. However, in the prior art, when the handle strip roll is gradually unwound and conveyed, after one handle strip roll is conveyed, a worker is required to assemble a new handle strip roll on the discharging frame, and then the front end of the new handle strip roll is moved to the next process, and a great deal of time is consumed in the process due to the fact that the new handle strip roll is mounted on the discharging frame again, the conveying efficiency of the handle strip is reduced, and the production efficiency of the packaging bag is greatly reduced. Disclosure of Invention The invention aims to solve the problems that in the prior art, when a handle strip material roll is gradually unfolded and conveyed by a handle strip conveying mechanism, after one handle strip material roll is conveyed, a worker is required to assemble a new handle strip material roll on a discharging frame, then the front end of the new handle strip material roll is moved to the next process, and a great amount of time is consumed in the process when the new handle strip material roll is newly assembled on the discharging frame, the conveying efficiency of the handle strip is reduced, and the production efficiency of a packaging bag is greatly reduced. In order to solve the technical problems, the invention discloses a handle strip feeding mechanism which comprises a rack and a discharging assembly arranged on the rack, wherein the discharging assembly comprises a discharging cabin capable of accommodating a plurality of handle strip rolls simultaneously, a plurality of discharging holes are arranged on one side of the discharging cabin side by side, the handle strip rolls are arranged in the discharging cabin, and the front ends of the handle strips on the handle strip rolls are respectively aligned with the corresponding discharging holes. And the relative positions of the discharging cabin and the feeding hole of the next procedure in the arrangement direction of the plurality of discharging holes are adjustable, and any discharging hole can be aligned with the feeding hole so as to input the front end of the handle strip on the corresponding handle strip roll into the feeding hole. According to the technical scheme, when the handle strip conveying mechanism works, a plurality of handle strip rolls are placed in the discharge cabin, the front end of each handle strip roll is aligned with the corresponding discharge port, then the position of the discharge cabin is adjusted along the arrangement direction, one discharge port is aligned with the feed port, the front end of one handle strip roll in the discharge cabin is conveyed to the next process through the one discharge port and the feed port, after one handle strip roll is conveyed, only the position of the discharge cabin is adjusted in the arrangement direction, the other discharge port is aligned with the feed port, then the front end of the other handle strip roll is conveyed to the next process through the other discharge port and the feed port, and the replacement of the handle strip roll in a reciprocating mode is carried out. In addition, when the conveying of the plurality of handle strip rolls is finished, for example, when the last handle strip roll is conveyed through the corresponding discharge hole, the staff can carry out supplementary placement on the handle strip roll in the discharge cabin again towards the positions corresponding to other feed holes, so that after the conveying of the last handle strip roll is finished, the position of the discharge cabin is continuously adjusted, and then the other handle strip rolls are conveyed, and the conveying efficiency of the handle strip is not affected. Further, the embodiment of the invention also discloses a handle
