Description

Gauze multichannel three-dimensional aggregate packaging system

Technical Field

The invention relates to the technical field of mechanical automation, in particular to a gauze multichannel three-dimensional aggregate packaging system.

Background

The sheet material generally undergoes the following steps from production to boxing: collecting and stacking, opening the paper box, boxing the sheet materials and buckling the paper box.

During the collection and handling of sheet material, particularly for those thicker, softer textured sheet products such as cotton sheets, gauze, etc., the problem of rollover and dumping of the stacked material often occurs. This is because when the bulk of the material is too high, its stability is lowered, which easily results in dumping. In order to accommodate the speed of the incoming material at the front stage and avoid rollover and dumping of the material during processing, it is desirable to retrofit existing material collection and handling equipment. Existing material collection devices are typically primary bins that directly stack sheet material together to form a higher stack of material, which increases the risk of material dumping. Therefore, there is a need to design a new type of material collection and handling device to improve the stability of the material stack, reduce the risk of dumping and to be able to adapt to the speed of the incoming material in the front section.

The existing automatic carton opening device is generally designed for cartons of specific sizes and shapes, and has poor adaptability to cartons of different sizes and shapes. In addition, many carton opening devices can damage the cartons when they are opened, affecting the effectiveness and quality of the package. Therefore, how to realize the universality and the high efficiency of the automatic carton opening device is an important problem faced by the current technology.

Cotton sheets and gauze are usually loaded into the paper box, however, after the paper box is loaded, the box cover is often unfolded, so that when the paper box is covered, only a manual mode is used for covering, and an operator needs to press the fluffy materials into the paper box by one hand and cover by the other hand. The manual mode buckle closure is good in effect, but low in efficiency, cannot adapt to the working beat of an automatic production line, and if a plurality of operators are arranged for buckle closure, the production cost is increased.

The two rotating cylinders 219 are both arranged on the lug folding telescopic seat 217, the lug folding plate 218 is fixedly connected with the rotating end of the rotating cylinder 219, and when the rotating cylinder 219 rotates, the lug folding plate 218 is driven to rotate, so that the two lugs 12 of the paper box 1 are inwards folded. Then, the conveying device 24 conveys the paper box 1 to the downstream, the lug folding moving platform 21 and the paper box 1 can move together to a distance to the lug folding guardrail 23, in the process, the lug folding plate 218 always presses the lug 12, fluffy materials in the paper box 1 are prevented from bouncing the lug 12, the paper box 1 moves to the lug folding guardrail 23 to be placed down, the lug 12 can be pressed, at the moment, the lug folding plate 218 can retract, the lug folding moving platform 21 resets, and the lug 12 of the next paper box 1 is pressed down again.

As shown in fig. 14 and 15, in order to achieve the above effect, the lug guard 23 needs to be higher than the case 11 and lower than the lug plate 218; because the lug plate 218 needs to be turned upwards to be vertical by the rotary air cylinder 219 when the lug plate 218 is retracted, so as to avoid interference with the upper cover 13 when the lug plate 218 is retracted, if the lug guard 23 is higher than the lug plate 218, the vertical lug plate 218 will interfere with the lug guard 23 when retracted, so that the lug guard 23 needs to be higher than the box 11 but lower than the lug guard 218.

As shown in fig. 14 and 15, the buckle closure mechanism 22 includes a buckle closure block 224, a buckle closure stay 227, a buckle closure baffle 229, a buckle closure pressure plate 225, a first buckle closure cylinder 222, a second buckle closure cylinder 221, a second rack 223, a second gear, a buckle closure stay cylinder 226, and a buckle closure baffle cylinder 228. The gland block 224 is fixedly connected with the first buckle closure cylinder 222, the first buckle closure cylinder 222 is longitudinally arranged, and when the first buckle closure cylinder 222 stretches out, the gland block 224 is driven to stretch out, so that the upper cover 13 can be bent in a forward tilting mode. The buckle cover stay bar 227 is fixedly connected with the moving end of the buckle cover stay bar cylinder 226, and the buckle cover stay bar cylinder 226 is arranged along the transverse direction and can drive the buckle cover stay bar 227 to move along the transverse direction. The buckle closure baffle 229 is fixedly connected with the moving end of the buckle closure baffle cylinder 228, and the buckle closure baffle cylinder 228 is vertically arranged and can drive the buckle closure baffle 229 to vertically move. The second rack 223 is fixedly connected with the moving end of the second buckle cover cylinder 221, the second gear is meshed with the second rack 223, the second gear is fixedly connected with the buckle cover pressing plate 225, the rotating shaft direction of the second gear is in the transverse direction, and when the second buckle cover cylinder 221 drives the second rack 223 to move, the second gear drives the buckle cover pressing plate 225 to rotate.

After the upper cover 13 is bent forward by the cover pressing block 224, the cover buckling support rod cylinder 226 drives the cover buckling support rod 227 to move below the upper cover 13, and then the cover buckling baffle cylinder 228 drives the cover buckling baffle 229 to move downward, so that the tail end of the upper cover 13 is bent downward to form the bending part 131. At this time, the buckle cover stay 227 moves laterally and is separated from the lower part of the upper cover 13, the buckle cover pressing plate 225 rotates to press the upper cover 13 downward, and the bending part is pressed into the box 11 to realize buckle cover.

As shown in fig. 17, it is noted that before the cover pressing plate 225 turns down the upper cover 13, the cover stay 227 needs to be moved laterally to avoid blocking the downward movement of the upper cover 13; but the lug folding guardrail 23 is always positioned above the box body 11 and below the upper cover 13, so that the lug 12 can be continuously pressed, and the lug 12 is prevented from being ejected by materials in the process of buckling the upper cover 13. Since the tab fence 23 is in a sheet shape, even if the tab fence 23 is located below the upper cover 13, the buckle cover of the upper cover 13 is not affected. After the cover is closed, the cover pressing block 224, the cover pressing plate 225 and the cover pressing plate 229 are reset, the paper box 1 with the cover is pushed by the conveying device 24 to move transversely to the next process, and in the process, the paper box 1 can be separated from the lug folding guardrail 23, but the lug folding guardrail 23 is transversely arranged and sheet-shaped, so that the paper box 1 with the cover is not blocked from moving transversely.
