Description

Paper bag packaging machine

Technical Field

The invention relates to the field of paper bag packaging machines.

Background

For the bottle cap packaging field, a film packaging machine is usually adopted to carry out operations such as bagging and thermoplastic sealing, but the operation such as label pasting and classification of the packaged whole stack of bottle caps is required to be carried out independently in the packaging mode, and the whole stack of packaged bottle caps has a certain volume, so that the carrying and moving are very troublesome, and the package damage can be caused in the process. Therefore, the packaging of a plurality of bottle caps adopts a paper bag body for packaging, and the operations of printing marks, sticking labels and the like can be carried out on the paper bag before packaging, which is very convenient. Due to the particularity of paper materials, the traditional manual bag opening and filling process is difficult to meet the modern packaging requirements.

In order to solve the problem of manual filling inefficiency, partially appear on the market comparatively automatic container bag packagine machine, for example public notice number is: the chinese invention patent of CN106516267A discloses an automatic bag opening device, which is characterized in that a bag opening is firstly opened by an upper sucker and a lower sucker, and then a bag is completely opened to a standard shape by the cooperation of an opening rod, a rotary cylinder and an opening cylinder in an opening mechanism. Although the paper bag is unfolded by the device, due to the fact that the paper bags are made of different materials, the bag openings of the paper bags made of soft materials are small and cannot be directly sucked by the suckers, and in actual use, the force for sucking the suckers is required to be adjusted repeatedly by a client, so that the device is very complicated, and the possibility of certain sucking failure still exists; for example, the device of chinese invention application CN201811148750.8, a "rotary bag opener for packaging bags", captures paper bags through a feeding device and moves them to a loading position, and moves the opening units left and right on a guide shaft through symmetrically arranged opening units to satisfy the opening of paper bags with different widths, wherein each of the rotary supporting plates in each opening mechanism is divided into an upper one and a lower one, so that the positions of the rotary supporting plates can be conveniently adjusted to satisfy paper bags with different height specifications, and the adaptability is strong.

Although the device has solved the problem of opening the bag failure through the mode of absorbing the upper and lower surface of container bag respectively, its whole step of opening the bag need including absorb the centre gripping upper bag face, remove the sack, absorb the centre gripping lower bag face and rotate a plurality of steps such as rotatory fagging struts, not only very loaded down with trivial details, and extravagant a large amount of time for packaging efficiency is very low.

As shown in fig. 1, a conventional paper packaging bag is schematically illustrated, when the paper packaging bag leaves a factory, an opening 100 for placing a workpiece is usually reserved at one end of the paper packaging bag, an extending edge 103 is reserved at the upper edge part of the opening 100 to facilitate opening of the bag mouth, and after the paper packaging bag contains the workpiece, a closing operation is required, that is, the end of the opening 100 is turned and folded to form a folding edge 101, so that a body 102 containing the workpiece is isolated from the outside.

In addition, the above-mentioned material receiving position 2b has at least two partition boards 21 arranged on the worktable 2 and arranged at intervals along the feeding direction, the extending direction of each partition board 21 is perpendicular to the feeding direction, and a storage tank 2c for storing the packaged bag body is formed between two adjacent partition boards 21.

The paper bag packaging machine has the working process as follows:

1. the sucking disc 81 is driven by the first driver 83 to move upwards, the sucking disc 81 is connected with an external negative pressure source and generates negative pressure to suck the paper bag at the material port of the storage bin 11, then the first driver 83 drives the sucking disc 81 to drive the paper bag to move downwards to the outlet 7b of the guide channel 70, and in the process of moving downwards, the extending edge 103 of the mouth of the paper bag touches the blocking piece 72 and is in the above-mentioned half-open state;

2. conveying the covers to be packaged into the feeding channel 50 from the previous process, stacking the covers in the feeding channel 50 in sequence along the extending direction of the feeding channel 50, after stacking a certain number of covers, extending the first shifting piece 61 into the feeding channel 50, pushing the stacked covers to the position of the downstream section of the feeding channel 50, then moving the first shifting piece 61 out, exposing the space for extending the second shifting piece 62 (namely, a shifting rod) due to the fact that the upstream section of the feeding channel 50 is separated after the covers are pushed, extending the second shifting piece 62 into the feeding channel 50, continuously pushing the stacked covers to the downstream of the feeding channel 50, and entering the guiding channel 70; because the distance between the first ends of the two guide sheets 71 is not less than the distance between the second ends, the whole stack of the covers entering the guide channel 70 will impact the inner wall of the guide channel 70, on one hand, the two guide sheets 71 are slightly moved forward to make the second ends with smaller distance extend into the half-opened bag mouth (the second ends of the two guide sheets are close to each other, which is equivalent to forming a relatively sharp head at the second end of the whole guide assembly), on the other hand, along with the step-by-step movement of the whole stack of the covers, the second ends of the two guide sheets 71 extending into the bag mouth gradually move away from each other to further open the bag mouth, then under the continuous pushing of the second toggle piece 62, all the covers enter the bag space, then the fifth driving mechanism 842 in the pushing assembly 84 drives the push plate 841 to push the packed paper bag a small distance downstream to move into the gap 30 formed between the press plate 31 and the workbench 2, and the part of the paper bag needing to be bent is opposite to the notch 20, namely is just positioned below the pressing plate 31;

3. the pressing plate 31 moves downwards under the driving of the first driving mechanism 32, and is pressed in the area adjacent to the opening of the paper bag, so that the front part of the whole paper bag is bent downwards to form a folded edge 101, the closing is completed, then the second driving mechanism 42 drives the tray 40 to move to the lower part of the paper bag after packaging, the tray 40 is driven to move upwards through the third driving mechanism 432, the lifting of the paper bag is completed, and then the second driving mechanism 42 drives the tray 40 to move to the corresponding position and place the paper bag at the material receiving position 2 b.
