Abstract
The invention discloses a labyrinth exhaust industrial heavy bag, wherein a single bag comprises a bag body, an organ type inserting edge, an upper opening and a bottom seal, and a winding drum bag comprises a bag body and an organ type inserting edge. The bag body is of a double-layer film structure, and the outer layer film and the inner layer film are respectively provided with micropores at specified positions; four linear adhesives are arranged between the longitudinal inner and outer films in the middle of the bag body to bond the inner and outer films so as to prevent the materials from entering the interlayer between the inner and outer films by mistake when the materials are filled. The inside and the outside of the whole bag body are communicated with each other, but the inner film and the outer film are staggered in micropore position and are not directly communicated with each other, solid materials or gas in the bag body need to turn in the interlayer of the bag body, and the path is similar to a labyrinth and can be discharged out of the bag. The gas has good fluidity, so the gas can be discharged along a curved path easily, the powder is not easy to bend, and a small amount of powder leaks into the interlayer at most, so the effect of easy gas discharge and difficult powder leakage can be achieved, and the contradiction that the industrial heavy bag needs to discharge gas but cannot leak powder when containing solid powder materials can be effectively solved.
Description
Technical Field
The invention relates to the technical field of packaging, in particular to a labyrinth exhaust industrial heavy bag.
Background
The industrial heavy bag is widely used for high-speed automatic packaging of industrial solid powder, and comprises automatic single bag packaging and FFS (flexible flat cable) roll bag packaging. Due to the stacking requirement, part of gas in the bag needs to be discharged after filling so as to ensure that the bag does not slip during stacking, and the gas is continuously discharged slowly by means of self weight until compaction so as to ensure that the bag does not chop during transportation. Generally, the above-mentioned venting requirements are achieved by punching the bag body or installing a one-way vent valve. The single exhaust valve exhausts, so that the quantity is small, the exhaust is slow, the quantity is large, and the cost is high; the holes are directly punched for exhausting, the hole diameter is reduced, the exhaust is not smooth, and the hole diameter is enlarged to directly leak powder. Therefore, a new exhaust structure is urgently needed to solve the contradiction that the exhaust is needed but the powder cannot leak. Based on the above, the invention provides a labyrinth exhaust industrial heavy bag to solve the above problems.

Furthermore, the number of the micro-holes is 4, and the micro-holes are longitudinally and bilaterally symmetrically arranged on the outer layer film on the front surface of the bag body.
Furthermore, an adhesive layer is arranged between the inner layer film and the outer layer film on the front side and the back side of the bag body and used for bonding the inner layer film and the outer layer film.
Furthermore, 4 groups of adhesive layers are respectively arranged on the front side and the back side of the bag body, and the adhesive layers are linear and symmetrically distributed on two sides of the longitudinal central axis of the bag body and penetrate through the whole longitudinal bag body from top to bottom.
Furthermore, a middle sealing welding seam for lapping the film sheets is longitudinally arranged in the middle of the back of the bag body.
Furthermore, the bag body is also provided with an upper opening and a bottom seal, the upper opening is distributed at the top of the bag body, and the bottom seal is distributed at the bottom of the bag body.
The invention has the beneficial effects that:
the invention adopts a double-layer bag structure, and the punching positions of the inner film and the outer film are staggered. The inner film of the organ type inserting edge is continuously punched and longitudinally penetrates through the bag body, and the outer film is longitudinally and discontinuously punched and is positioned at the edge of the front side of the bag body; the linear adhesive layer is arranged in the middle of the bag body and longitudinally penetrates through the bag body, and the inner film and the outer film in the middle of the whole bag body are bonded into a whole in the longitudinal direction, so that materials are prevented from being filled into the interlayer during filling. After the packaging bags are filled with materials and stacked, the inner layer films of the two side organ type inserting edges are provided with micropores, the whole bag is longitudinally penetrated, the number is large, the gas in the bag has good fluidity, and the gas is easily extruded into the interlayer of the inner and outer films after being pressed. The solid powder in the bag has poor flowability and is blocked by an outer layer film, so that the powder is not easy to flow into the interlayer, and at most a small amount of the powder is brought into the interlayer by airflow. After the gas enters the interlayer, a low-pressure part is always searched for pressure relief, and the gas is easy to flow to a nearby outer layer film hole and flow out of the bag due to good gas fluidity. And a small amount of powder leaking into the interlayer along with the airflow needs a large amount of airflow to carry a long bending path to move to the holes of the outer layer film because of poor flowability, so that the solid powder leaking out of the holes of the outer layer film is very little, and the bag body achieves the effect of easy exhaust and difficult powder leakage by utilizing the difference of gas and solid flowability.
