Description

Technical Field

[0001] This utility model relates to the field of moisture-proof technology for ammonium sulfate packaging bags, specifically a moisture-proof lining structure for ammonium sulfate packaging bags. Background Technology

[0002] Ammonium sulfate packaging bags are specially designed containers for holding ammonium sulfate. They can be divided into large ton bags and small woven bags. Typically, the bags are double-layered, with a functional PE film inside and a woven fabric outside.

[0003] However, relying solely on a single-layer PE film to isolate moisture means that the PE molecular chains will still undergo slight swelling under prolonged water immersion, resulting in nanoscale cracks on the surface, which then become new permeation channels. Furthermore, the probability of damage is relatively high with only a single-layer PE film. Therefore, a moisture-proof lining structure for ammonium sulfate packaging bags is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof lining structure for ammonium sulfate packaging bags, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a moisture-proof lining structure for ammonium sulfate packaging bags, comprising:

[0006] The PE liner includes a bag body and a first columnar feed pipe, the first columnar feed pipe being fixed at the upper middle part of the bag body;

[0007] The isolation assembly includes a partition, a second columnar feed tube, an L-shaped support column, an inflation tube, and a rubber stopper. The partition is wrapped around the outside of the bag. The second columnar feed tube is fixed at the middle of the upper end of the partition and wrapped around the first columnar feed tube. The L-shaped support column is glued between the bag body and the partition and is located at the four corners of the bag body. The inflation tube passes through and is fixed at the upper end of the partition and is located next to the second columnar feed tube. The rubber stopper is plugged at the outlet of the inflation tube.

[0008] Furthermore, the isolation assembly also includes a support plate and a support plate. The support plate is fixed to the upper and lower ends of the L-shaped support column and is located between the bag body and the partition. The support plate is fixed to the middle of the lower end of the bag body.

[0009] Furthermore, the edges and corners of the L-shaped support column, support plate, and support disk are all rounded and polished smooth.

[0010] Furthermore, both the partition and the second columnar feed tube are made of PE film, and nitrogen is filled between the partition and the bag body.

[0011] Furthermore, both the partition and the bag body are wrapped inside the outer woven bag, and the upper ends of the first columnar feed pipe and the second columnar feed pipe are glued to the inner wall of the feed pipe of the outer woven bag.

[0012] Furthermore, it also includes an air-leakage prevention component, which includes a semi-cylinder and a groove. There are two semi-cylinders, one on the inner wall of the first columnar feed pipe, and the other is located in the middle of the outer side of the semi-cylinder.

[0013] Furthermore, the air leakage prevention component also includes an I-shaped slot and an I-shaped block. The I-shaped slot is opened on the side of one of the semi-cylinders, and the I-shaped block is fixed on the side of the other semi-cylinder, and the I-shaped block is inserted into the I-shaped slot.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes an isolation assembly to sequentially glue L-shaped support columns and support plates onto the bag body. The bag body and the first columnar feed tube are then inserted into the partition and the second columnar feed tube. Subsequently, the partition and the second columnar feed tube are inserted into the outer woven fabric. After tidying up, the L-shaped support columns are glued to the four corners of the partition. Using a hot-pressing process, the upper ends of the first and second columnar feed tubes are adhered to the feed tubes of the outer woven fabric. The interior is then smoothed. Before use, nitrogen is injected into the partition and bag body through the inflation tube, and the rubber stoppers are then sealed. Ammonium sulfate is then introduced into the bag body through the first columnar feed tube. After filling, the first and second columnar feed tubes are tied tightly. This design constructs a "microcapsule-like" barrier structure, improving moisture-proof performance and damage resistance. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this utility model is a moisture-proof lining structure for ammonium sulfate packaging bags, comprising:

[0026] The PE liner includes a bag body 10 and a first columnar feed pipe 11, which is fixed at the middle of the upper end of the bag body 10.

[0027] PE lining has moisture-proof and leak-proof properties.

[0028] The isolation assembly includes a partition 20, a second columnar feed tube 21, an L-shaped support column 22, an inflation tube 25, and a rubber stopper 26. The partition 20 is wrapped around the bag body 10. The second columnar feed tube 21 is fixed at the middle of the upper end of the partition 20 and is wrapped around the first columnar feed tube 11. The L-shaped support column 22 is glued between the bag body 10 and the partition 20 and is located at the four corners of the bag body 10. The inflation tube 25 passes through and is fixed at the upper end of the partition 20 and is located next to the second columnar feed tube 21. The rubber stopper 26 is plugged at the outlet of the inflation tube 25.

[0029] The isolation assembly also includes a support plate 23 and a support plate 24. The support plate 23 is fixed at the upper and lower ends of the L-shaped support column 22 and is located between the bag body 10 and the partition 20. The support plate 24 is fixed at the lower middle part of the bag body 10.

[0030] The edges and corners of the L-shaped support column 22, support plate 23 and support disk 24 are all rounded and polished smooth.

[0031] Both the partition 20 and the second columnar feed tube 21 are made of PE film, and nitrogen is filled between the partition 20 and the bag body 10.

[0032] The partition 20 and the bag body 10 are both wrapped inside the outer woven bag, and the upper ends of the first columnar feed pipe 11 and the second columnar feed pipe 21 are glued to the inner wall of the feed pipe of the outer woven bag.

[0033] The partition 20, the second columnar feed pipe 21, the bag body 10, and the first columnar feed pipe 11 form an air-filled space. The L-shaped support column 22, the support plate 23, and the support plate 24 provide support. The air-filling pipe 25 is used to inflate the partition 20. The rubber stopper 26 provides a sealing function.

[0034] Working principle:

[0035] L-shaped support columns 22 and support plates 23 are sequentially glued to the bag body 10. The bag body 10 and the first columnar feed tube 11 are then inserted into the partition 20 and the second columnar feed tube 21. Subsequently, the partition 20 and the second columnar feed tube 21 are inserted into the outer woven fabric. After tidying up, the L-shaped support columns 22 are glued to the four corners of the partition 20. Using a hot-pressing process, the upper ends of the first columnar feed tube 11 and the second columnar feed tube 21 are adhered to the feed tubes of the outer woven fabric. The interior is then smoothed out. Before use, nitrogen is injected into the partition 20 and the bag body 10 through the inflation tube 25, and the glue stopper 26 is then sealed tightly. Ammonium sulfate is then introduced into the bag body 10 through the first columnar feed tube 11. After filling, the first columnar feed tube 11 and the second columnar feed tube 21 are tied tightly. When not in use, the bag body 10 and the partition 20 can be rolled up around the L-shaped support columns 22 for easy storage.

[0036] This step involves constructing a "microcapsule-like" barrier structure to improve moisture resistance and damage prevention.

[0037] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The air-proof component includes a semi-cylinder 30 and a groove 31. There are two semi-cylinders 30, which are located on the inner wall of the first columnar feed pipe 11, and the groove 31 is located in the middle of the outer side of the semi-cylinder 30.

[0039] The leak-proof component also includes an I-shaped slot 32 and an I-shaped block 33. The I-shaped slot 32 is opened on the side of one of the semi-cylinders 30, and the I-shaped block 33 is fixed on the side of the other semi-cylinder 30 and is inserted into the I-shaped slot 32.

[0040] Both semi-cylinders 30 are made of elastic silicone. The groove 31 facilitates the clamping of the first columnar feed tube 11 and the second columnar feed tube 21. The I-shaped slot 32 and the I-shaped block 33 serve as limiters.

[0041] Working principle:

[0042] After the bag body 10 is filled with ammonium sulfate, the two semi-cylinders 30 are joined together, the I-shaped card block 33 is inserted into the I-shaped card slot 32, and the feed tube of the outer woven fabric is tied with a cable tie so that the cable tie is stuck in the groove 31 and tied, and the first columnar feed tube 11 and the second columnar feed tube 21 are tied into the groove 31.

[0043] This step increases the tightness of the bag opening after it is tied, preventing moisture from entering through the bag opening.
