Embodiment 1

[0027] Figure 1-2 , Figure 8-11 , the basic structure of a paper bag with holes in the outer layer of a multi-layer fruit paper bag. The upper end of the paper bag is an open end, and the outer layer of the multi-layer paper bag has holes. The paper bag may present a single M-shaped or multiple M-shaped folded paper bags. It is mainly aimed at bagging machines that use pneumatic opening or pneumatic working methods to solve the problem of difficult bagging of multi-layer paper bags. The outer layer of the paper bag is provided with one or more holes, and the function of the holes is mainly air holes. It can solve the opening and conveying problems of paper bags. Generally speaking, except for the innermost layer, multi-layer paper bags have air holes, so that when the paper bag is opened, the pneumatic suction cup can open the multi-layer paper bag at one time; For other layers, open the pores to the sub-outer layer and so on.

Embodiment 2

[0037] image 3 , Figure 4 , Figure 9 , Figure 12 , a basic structure in which the inner layer of a multi-layer fruit paper bag is provided with metal sheets or wires, the upper end of the paper bag is an open end, the inner layer of the multi-layer paper bag is provided with metal sheets or wires; , the side is a one-shaped paper bag or a single M-shaped or multiple M-shaped folded paper bag. It is mainly aimed at bagging machines with magnetic opening or magnetic working methods to solve the problem of difficult bagging of multi-layer paper bags. As far as the opening method is concerned, as long as the metal sheet is set on the innermost layer, the multi-layer paper bag can be opened by using the magnetic principle. For the paper bag itself and the bagging machine, the technology becomes relatively simple, and the mechanical cost is also low. Becomes relatively low, this feature is also very worth implementing, this is the main difference from the implementation colu...

Embodiment 3

[0040] Image 6 , 11 , 12. A multi-layer fruit paper bag, the positioning holes or grooves and the upper edge are provided with tear lines; the paper bag can be single-layer or multi-layer. The purpose of setting the tear-off line on the positioning hole of the single-layer or multi-layer paper bag is to remove the paper bag from the automatic bagging equipment and simplify the bagging process of the automatic bagging equipment. With the tear-off line, the paper bag can be directly removed from the positioning device. Tear up and down, save unnecessary other links. Generally speaking, the positioning hole passes through the multi-layer paper bag, and the processing method is the same as that of the single-layer paper bag. It does not need to consider whether the separation and position of the multi-layer paper bag, the opening and sealing become relatively easy and simple.

Abstract

The invention discloses a multilayer paper bag for fruits. The upper end of the paper bag is open. Holes are formed in an outer layer of the paper bag, or metal sheets or threads are arranged on an inner layer of the paper bag. A fruit bagging line is arranged at the center of the upper end of the front side of the paper bag downwardly. The side face of the paper bag is of an I-shaped paper bag oran M-shaped folded paper bag. Positioning holes or grooves can be formed in the upper end of the rear side, or in the upper ends of the front and rear sides, of the paper bag. The flat area of the paper bag can be reduced relatively through folding of the paper bag, automatic bagging equipment is downsized, and bagging operations are facilitated. The holes in the outer layer of the paper bag canfacilitate the opening of the multilayer paper bag by a pneumatic bagging device; the metal sheets or threads on the inner layer of the paper bag can facilitate the opening of the multilayer paper bagby a magnetic bagging device; through the positioning holes or grooves in the paper bag, paper bags in different specifications can be unified in size standard, so that convenience is brought to themechanized and intelligent bagging equipment.

Description

technical field [0001] The invention belongs to the field of fruit production technology and fruit paper bags. Background technique [0002] The biggest advantage of fruit bagging in the fruit production process is that it can improve the appearance quality of apples and reduce pesticide residues. The improvement of appearance quality is mainly reflected in the smooth surface and comprehensive coloring of apples. Traditional paper bags come in a variety of styles and specifications. There is no uniform standard and lack of specifications, which makes the automatic bagging equipment more complicated, especially the bagging machine for multi-layer paper bags, which is not conducive to the automatic bagging operation of fruits. Contents of the invention [0003] The present invention can solve the deficiencies of the above-mentioned problems. Air holes are set on the outer layer of the multi-layer paper bag, which provides the possibility for a multi-layer paper bag bagging m...
