Sealing and cutting device and method for manufacturing small-opening clip chain bag with same

Abstract

The invention relates to the technical field of sealing and cutting devices, in particular to a sealing and cutting device and a method for manufacturing a small-opening clip chain bag with the same. The sealing and cutting device comprises a cross beam, a cutter mounting bracket connected with the cross beam, a first sealing cutter, a second sealing cutter and a third sealing cutter, wherein the second sealing cutter and the third sealing cutter are vertically and adjustably arranged on the cutter face of the first sealing cutter respectively; and the first sealing cutter, the second sealing cutter and the third sealing cutter are adjustably arranged on the cutter mounting bracket. Through the cooperation of the first sealing cutter, the second sealing cutter and the third sealing cutter, the opening of a clip chain bag is changed into a small opening from the traditional large opening, so powdery products are prevented from being incautiously spilled due to over-large opening during pouring, and the sealing and cutting device brings convenience to a user.

Description

technical field [0001] The invention relates to the technical field of sealing and cutting devices, in particular to a sealing and cutting device and a method for making small opening zipper bags. Background technique [0002] The sealing and cutting device can not only cut the plastic film, but also use the thermal bonding strength to seal the incision, so the sealing and cutting device is used more and more widely, and the sealing and cutting device is also used when making zipper bags. The traditional production process of zipper bags The sealing and cutting device used only has the first sealing and cutting knife, and is perpendicular to the movement direction of the plastic film for the zipper bag. The whole side of the zipper bag produced is open, such as figure 1 , although it can be sealed with the matching concave and convex strips in the zipper bag after use, if such a large-open zipper bag is used to hold powdered items such as washing powder or milk powder, when ...

Problems solved by technology

[0002] The sealing and cutting device can not only cut the plastic film, but also use the thermal bonding strength to seal the incision, so the sealing and cutting device is used more and more widely, and the sealing and cutting device is also used when making zipper bags. The traditional production process of zipper bags The sealing and cutting device used only has the first sealing and cutting knife, and is perpendicular to the movement direction of the plastic film for the zipper bag. The whole side of the zipper bag produced is open, such as figure 1 , although it can be sealed with the matching concave and convex strips in the zipper bag after use, if such a large-open zipper bag is used to hold powdered items such as washing powder or milk powder, when the zipper bag is opened and dumped Powdery items will be accidentally spilled due to the large opening, which will bring great inconvenience to life

[0003] Patent No. 200720056995.9 Chinese Utility Model Patent introduces a packaging sealing bag, which includes a heat-sealing edge and a bag body, the heat-sealing edge seals the four sides of the bag body, and a sealing strip along an oblique direction is provided at one corner of the bag body. The sealing strip is the corresponding concave and convex strips on both sides of the bag body. The two ends of the sealing strip are connected with the ironing edge, which is the so-called small opening zipper bag, but this patent does not introduce the use of the small opening zipper bag. The sealing and cutting device and the production method of the small opening zipper bag are not available at present, and there is no patent introducing the sealing and cutting device used in the small opening zipper bag and the method of making the small opening zipper bag
