Embodiment 1

[0031] see figure 1 , a heat-sealable three-dimensional paper bag making machine, which includes a frame 1, one end of the frame is provided with an outer paper roll 2, and an outer paper roll 3 is set on the outer paper roll, and the outer paper roll The outer layer of paper on 3 is conveyed to the film application mechanism 5 under the guidance of several guide rollers 4, and the film application mechanism 5 is provided with a 10-15mm wide heat-sealing film 181 for sealing at the sealing position of each paper bag, The heat-sealing film 181 is a substance that is non-sticky at room temperature and viscous after heating, such as hot melt adhesive, plastic film, etc. The lower station is provided with a cooling mechanism 6 for cooling the heat-sealing film 181 to facilitate subsequent bag-making operations The lower station of the cooling mechanism 6 is provided with a cutting roller 11, and the cutting roller 11 is used to cut out a smooth opening 182 for the fruit handle to ...

Embodiment 2

[0038] see figure 2, one end of the frame 1 located at the outer paper roll 2 is provided with an inner paper roll 7, the inner paper roll 7 is covered with an inner paper roll 8, and the frame 1 is provided with an inner and outer paper composite mechanism 9. It is used to transport the inner paper and the outer paper forward after overlapping.

[0039] The inner and outer paper composite mechanism 9 is located between the film applying mechanism 5 and the cutting roller 11, and includes at least one pair of drive rollers 91, guide plates 92, cutters 93 for cutting the inner paper and inner and outer paper composites arranged in sequence. Rollers 94, each pair of driving rollers 91 includes a driving roller and a driven roller, the axes of the driving roller and the driven roller are arranged parallel to each other, and the inner paper conveyed from the inner paper roller 7 is Pass between the driving roller and the driven roller, the driving roller rotates to drive the inn...

Embodiment 3

[0043] The inner and outer paper composite mechanism 9 is an inner and outer paper composite roller 94, and the inner and outer paper composite mechanism 9 is arranged on the upper station of the film applying mechanism 5, and the inner and outer paper composite mechanism 9 makes the inner paper and the outer paper continuously Composite together, the heat-sealing film is set on the inner paper.

Abstract

The invention discloses a three-dimensional paper bag making machine capable of achieving heat sealing. The three-dimensional paper bag making machine comprises a rack, wherein an outer paper roll isarranged at one end of the rack; outer-layer paper on the outer paper roll is conveyed to a film applying mechanism under the guidance of a plurality of guide rollers; the film applying mechanism is provided with a heat sealing film for sealing at a sealing position of each paper bag; a cutting roller is arranged at a lower station of the film applying mechanism; the cutting roller is used for cutting a smooth opening for a fruit stem to pass through on the paper; an upper rubber roller is arranged at a lower station of the cutting roller; a three-dimensional forming mechanism for extruding the paper into a three-dimensional cavity is arranged at a lower station of the upper rubber roller; the paper passes through the three-dimensional forming mechanism, and then the paper bag is pressed to be superposed from top to bottom by a pressing roller; and a bag cutting roller for cutting the continuous paper bag into single paper bags is arranged at a lower station of the pressing roller. Thethree-dimensional paper bag making machine disclosed by the invention is capable of producing single-layer or double-layer paper bags capable of achieving heat sealing, and high in folding precision;and the produced paper bags are suitable for being used on an automatic bagging machine, and have a relatively good market popularization prospect.

Description

technical field [0001] The invention relates to the technical field of young fruit bagging equipment, in particular to a three-dimensional paper bag making machine. Background technique [0002] The main purpose of bagging young fruit is to prevent the fruit from being attacked by birds, pests, and damage from wind, rain and sunlight during the growth process. Scratched by branches during growth. Bagging can produce a local greenhouse effect, keep the fruit at proper humidity and temperature, increase the sweetness of the fruit, improve the luster of the fruit, increase the yield of the fruit, and shorten its growth period. At the same time, because no pesticides are needed during the growth process, the fruits are of high quality and pollution-free, reaching international standards. [0003] With the continuous improvement of technology, three-dimensional paper bags are better than plastic bags. The three-dimensional paper bag means that one end of the cover bag is close...
