When bagging fruit, double-layer fruit bags are generally used, wherein the inner bag paper of the double-layer fruit bag is wax-soaked paper, and the outer bag paper is kraft paper coated with ink on the inner surface. Fruits grown in double-layer fruit bags are high-quality fruits. Compared with fruits without fruit bags or single-layer fruit bags, they have positive fruit shape, no bird pests, no branch scratches and deformation, and high Pile obvious advantages. In addition, because the fruit is covered with double-layer fruit bags, it can effectively avoid sun damage, wind damage and sun burn, so that the formed fruit has the advantages of smooth fruit surface, bright color, moderate fruit size, moderate crispness and hardness, and good fruit flavor. Generally, the fruits grown by this cultivation method of covering the fruits with double-layer fruit bags contain high content of soluble solids and less pesticide residues, which belong to pollution-free high-quality fruits.

The continuous inner bag paper tube is pulled forward by the paper pulling roller, and when it passes the first cutting roller 7, it is cut off by the cutting knife installed along the axial direction on the first cutting roller 7, and the single inner paper bag is separated from the continuous inner paper belt, separated The inner paper bag coming out enters the paper feeding roller 8, is transported forward by the paper feeding belt, and is ready to enter the inner and outer bag compounding device in the next process. At the same time, the outer paper tape is conveyed to the next process.

4) The fruit bag laminating process includes the compounding of a single inner paper bag and a continuous outer paper tape. The compounding of a single inner paper bag and a continuous outer paper tape is completed by the joint action of two relatively rotating belt rollers and belts in the compounding station. The continuous outer paper tape is creased by two creasing rollers with a diameter of φ40 in the creasing plate 13, and the large edge retracting mechanism 14 slowly folds the large edge of one side of the outer paper tape along the creasing line, and the paper edge close to half the width Flip upwards to form a half-folding trend, the folded outer paper tape (in a tubular shape but without edge sealing) continues to be conveyed forward, and the half-folded outer paper tape (in a cylindrical shape but without edge sealing) continues to be conveyed forward, after the second The upper side rubber roller wheel 15 completes the gluing on the other side (narrow side). The second upper side rubber roller wheel 15 is made of upper side rubber pot 27 and two diameters as upper side rubber roller wheel 25 and back pressure roller 26 pairs of rollers of φ 62.5 to complete the upper side glue work. The outer paper tape after upper side gluing meets the iron wire sent by the wire feeding device 16 while advancing, and the cut iron wire with a length of about 20 mm is glued to the outer paper bag coated side by the broken wire roller in the wire feeding device 16. On the narrow side of the glue, the iron wire bonded in the fruit bag plays the role of hanging the fruit bag to the branch when bagging is implemented.

As shown in Figure 9, the small side 38 of the outer paper bag coated with glue and iron wire can be folded by the small side mechanism 17, so as to be bonded together with the big side 39 just folded up, and complete the outer bag. Socket molding work. At this time, the outer paper tape is still a continuous long paper tape without cutting and back cover.

5) The post-processing part is mainly to make air holes on the surface of the double-layered fruit bag, print the logo, cut out the incision and chamfer on both sides of the bottom of the fruit bag.

The function of the air hole line roller 18 is to die-cut several (2 or 3) air lines with a length equal to the length of the bag on the front and back of the outer bag, so that the fruit can be kept in the bag for a long time (several months). Guaranteed breathability.

The effect of incision is as the drainage port 36 of paper bag. The concrete effect is: one, if the rainwater of rainy day enters the bag, rainwater can flow out from the incision at the bottom of the bag in time; , This mouth is also the tearing mouth used when tearing the bag.

The effect of chamfering mechanism 21 is the shape of the bottom edge of the outer bag. In addition, after chamfering and sealing the back, the straight edge cutting the right-angled edge can be exposed without affecting the function of the straight edge for water leakage.

6) Out of bag process

Mainly use the second cutting roller 22 to cut the continuous double-layer fruit bag into a single fruit bag, and use the upper glue roller 24, wherein the upper glue roller 28 applies the glue to the bottom fold of the outer paper bag. At the edge, a row of gripper teeth in the bag receiving groove 19 will wrap up the glued paper edge to cover the bottom, and rotate after biting. , the double-layer paper bags are dropped and collected, and the automatic bag-making process of the double-layer apple bags is completed.

The whole device is simple in principle, practical, reliable, compact in layout (total length 7.5m), low in manufacturing and use costs, and high in bag making quality.
