[0002] Traditional powder materials are generally loaded through composite nylon bags. Although this nylon bag will not cause the problem of powder overflow, the powder packaging bag is a packaging bag specially used for packaging powdered items. At present, the powder is packaged in woven bags. There is a certain gap between the warp and weft of the woven bag, and when subjected to external force, the warp and weft woven lines will move, and the puncture resistance is poor; the packaged items are easily affected by moisture, and the moisture and humidity resistance is poor, which is not conducive to protecting the packaged items; and the low-temperature impact resistance is poor, and it is easy to age; the woven bag is easy to slip and collapse during stacking. In addition, if the woven bag is made of recycled materials, its quality is unstable, there are many impurities, and the tensile strength and toughness are average. It is necessary to solve the problem that the woven packaging bag for powder packaging in the existing technology has good anti-slip, moisture and humidity resistance, which is conducive to better protection of the packaged items. The Chinese patent discloses a moisture-absorbing and dust-proof powder material packaging bag (authorization announcement number CN217806220U). The patent technology discloses a moisture-absorbing and dust-proof powder material packaging bag, which relates to the field of powder material packaging technology. The utility model comprises an outer bag body, an inner bag body is fixedly connected to the inner part of the outer bag body, and two feeding hoppers are fixedly connected to the two sides of the top of the inner bag body, wherein a drying mechanism for placing a desiccant is arranged in the middle of the inner bag body, and handle holes for carrying the packaging bag are arranged on the top of both sides of the outer bag body. The improved utility model is provided with the inner bag body, the outer bag body and the drying mechanism, etc., so that the powder material packaging bag can be conveniently loaded and the powder flying can be avoided when the powder material is unloaded under the structural design of the outer bag body and the inner bag body when in use, and the moisture and humidity resistance of the packaging bag can be improved under the setting of the drying mechanism, and the practicality of the packaging bag is effectively improved. At the same time, due to the setting of the handle hole on the top of the outer bag body, the packaging bag can be conveniently taken and placed, and the loading of the packaging bag is convenient. This patented technology solves the problem that a large amount of dust is still generated when loading and unloading materials, and it is difficult to carry because the surface of the bag body is smooth and there is no leverage.

[0030] One end of the locking buckle belt 205 is integrally provided with a locking buckle frame 206, and the other end of the locking buckle belt 205 is integrally connected with a removal buckle belt 207, and the inner wall of the removal buckle belt 207 is provided with a latching inner groove 208, and the latching inner groove 208 is clamped on the inner side of the locking buckle frame 206; and one end of the removal buckle belt 207 passes through the feed top bag 201, and is fixed with a pull ring 209;

[0031] The outer surfaces of the protective outer frame 101 and the protective inner frame 103 are both provided with anti-slip convex patterns.

[0032] Working principle:

[0033] The protective outer frame 101 is made of non-slip rubber material, and the flexible connecting bucket 102 connected between the protective outer frame 101 and the protective inner frame 103 is made of flexible rubber material. When the protective inner frame 103 is contracted, it can be stored inside the protective outer frame 101 through the flexible connecting bucket 102, so that the packaging outer bag structure 1 can be retracted and stored;

[0034] When filling the powder into the inner packaging bag 3, the powder is placed into the inner packaging bag 3 through the feeding tube bag 204, and at the same time, the air inside the inner packaging bag 3 is discharged to the inside of the outer packaging bag structure 1 through the second exhaust hole 32, and is discharged to the outside through the exhaust hole 105 of the outer feeding top bucket 104 of the outer packaging bag structure 1. The positions of the second exhaust hole 32 and the exhaust hole 105 are staggered, so that the air inside the inner packaging bag 3 can be discharged, while the air outside the outer packaging bag structure 1 cannot circulate into the inner packaging bag 3 due to the air pressure, so as to facilitate the sealing of the inner packaging bag 3.

[0035] When the outer packaging bag structure 1 is filled with powder, the protective outer frames 101 at the upper and lower ends can be stretched to stretch the protective inner frame 103 between the protective outer frames 101, and the protective inner frame 103 can be extended and connected through the flexible connecting bucket 102, so that the outer packaging bag structure 1 can increase the volume of the powder storage. At the same time, the outer packaging bag structure 1 can be stacked up and down through the protective outer frame 101, and the protective outer frame 101 and the protective inner frame 103 made of anti-skid rubber material and the convex anti-skid embossing on the outside have a double anti-skid effect, which can effectively increase the anti-skid property of the outer packaging bag structure 1.

[0036] When the feeding tube bag 204 is locked and closed, the pull ring 209 is manually pulled, and the pull ring 209 pulls the removal buckle 207. The removal buckle 207 passes through the inner groove 208 of the latch and moves along the locking buckle frame 206. The locking buckle 205 tightens and locks the feeding tube bag 204, completing the automatic sealing structure 2 to seal the packaging outer bag structure 1 and the packaging inner bag 3.
