Description

Technical Field

[0001] This utility model relates to the technical field of equipment for producing FIBCs (Flexible Intermediate Bulk Containers), and in particular to a composite PP FIBC with moisture-proof and leak-proof functions. Background Technology

[0002] In the practical application of FIBCs, the flexibility of the bottom tightening method is a key factor affecting their adaptability to different loading volumes. However, traditional FIBCs have significant defects in this aspect, making it difficult to meet diverse usage needs and causing many inconveniences to the loading, transportation and storage of goods. The bottom tightening method of FIBCs is extremely limited, with fixed sealing being one of the most common forms. Once this structure is formed, the tightness cannot be changed and cannot be adjusted according to the amount of items inside the bag. When the amount of items loaded is small, there will be a lot of empty space at the bottom of the fixed-seal FIBC. During transportation or handling, the items will shake freely inside the bag, which can easily cause collision damage between items. Furthermore, the shaking of the items will cause uneven stress on the bottom of the bag, which will accelerate the wear and tear of the bag in the long run and shorten the service life of the FIBC. Therefore, the above problems need to be solved. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite PP container bag with moisture-proof and leak-proof functions.

[0005] Preferably, the lifting component includes a movable hole in the inner wall of the bag and a diversion hole in the mounting block. A traction rope is slidably disposed in the movable hole. The traction rope is convex upward and is connected to the diversion hole.

[0006] Preferably, the shrinking component includes a guide block fixed to the outer wall of the bottom of the bag and a movable groove opened on the inner wall of the bottom of the bag. The guide block has two flow holes. A tension rope is slidably arranged in the movable groove and the flow holes. A fixing block is fixed to one side of the guide block. A limiting hole for the tension rope to pass through is opened on the side wall of the fixing block.

[0007] Preferably, the side wall of the fixing block is slidably provided with a pressing block for limiting the tightening degree of the tensioning rope, a return spring is installed at the bottom of the pressing block, and a limiting groove for the tensioning rope to slide is opened on the side wall of the pressing block, and the inner wall of the limiting groove movably abuts against the tensioning rope.

[0008] Preferably, the inner sidewall of the bag is fitted with a shock-absorbing block for protecting the items inside the bag. The shock-absorbing block is made of EVA foam material and has a right-angled trapezoidal structure.

[0009] Preferably, the drying layer consists of two layers of nonwoven fabric, with montmorillonite desiccant particles filling the space between the two layers of nonwoven fabric.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the combination of the mounting block and the traction rope can disperse the pulling force during lifting, avoid excessive local force leading to damage to the bag body, and facilitate manual handling, improving operational convenience; the combination of the anti-collision block and the bubble shock absorber can reduce the impact force and provide all-round protection for the items inside the bag, especially suitable for protecting irregular or fragile items; the setting of the shrinking component can realize the shrinking of the bottom of the bag body, which makes it easy to adjust the tightness according to the number of items inside the bag and maintain the stability of the tightened state, solving the problem that the traditional container bag has a single bottom tightening method and it is difficult to flexibly adjust the bottom tightening degree according to the number of items inside the bag.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model discloses a composite PP container bag with moisture-proof and leak-proof functions, including a bag body 1. The bag body 1 includes an outer tensile layer 9 and an inner drying layer 8. Both ends of the bag body 1 are provided with foldable fabric 3 for easy folding. The foldable fabric 3 facilitates flexible folding of the bag body 1, saving transportation and storage space, and at the same time, it is not easy to damage the structure of the bag body 1 when folding. The top two outer walls of the bag body 1 are symmetrically fixed with mounting blocks, which provide support points for the lifting components. The mounting blocks are provided with lifting components. The bottom outer wall of the bag body 1 is provided with shrinking components. The bottom of the bag body 1 is fitted with an air bubble shock absorber 6, which absorbs the impact force during transportation, reduces the collision between the items and the bottom of the bag body 1, and protects fragile items from damage.

[0015] In this invention, the lifting component includes a movable hole in the inner wall of the bag body 1 and a diversion hole in the mounting block. A traction rope 2 is slidably disposed in the movable hole. The traction rope 2 is convex and connects to the diversion hole. The lifting component facilitates the dispersion of tension during lifting, preventing excessive local stress that could damage the bag body 1. It also facilitates manual handling and improves operational convenience. The shrinking component includes a guide block 5 fixed to the outer wall of the bottom of the bag body 1 and a movable groove in the inner wall of the bottom of the bag body 1. The guide block 5 has two flow holes. A tension rope 4 is slidably disposed in the movable groove and the flow holes. A fixing block 10 is fixed to one side of the guide block 5. The guide block 5 facilitates the guidance of the tension rope 4, ensuring that the tension rope 4 is evenly stressed and that the bottom of the bag body 1 shrinks flat and is tightly sealed. The fixing block 10 has a limiting hole on its side wall for the tension rope 4 to pass through. The fixing block 10 facilitates the fixing of the tension rope 4, preventing it from loosening and ensuring the stability of the seal at the bottom of the bag body 1. The fixed block 10 has a sliding clamping block 11 on its side wall to limit the tightening degree of the tensioning rope 4. A return spring 12 is installed at the bottom of the clamping block 11. The side wall of the clamping block 11 has a limiting groove for the tensioning rope 4 to slide. The inner wall of the limiting groove moves against the tensioning rope 4. The clamping block 11 can press the tensioning rope 4 tightly under the action of the return spring 12 to prevent it from loosening on its own and ensure a stable tightening state. At the same time, it is easy to adjust the tightening degree. The inner side wall of the bag body 1 is attached with an anti-collision block 7 to protect the items inside the bag. The anti-collision block 7 is made of EVA foam material and has a right-angled trapezoidal structure. The anti-collision block 7 can reduce the side impact force and form all-round protection for the items inside the bag. It is especially suitable for protecting irregular or fragile items. The drying layer 8 is composed of two layers of non-woven fabric. Montmorillonite desiccant particles are filled between the two layers of non-woven fabric. The drying layer 8 can continuously absorb moisture inside the bag, maintain a dry environment inside the bag, and effectively prevent the items from getting damp and deteriorating.

[0016] Working Principle: When using this invention, the contraction component at the bottom of the bag 1 plays a crucial role when loading items. The tension rope 4 is slidably positioned in the flow hole of the guide block 5 and the movable groove on the inner wall of the bottom of the bag 1. The guide block 5 provides guidance for the tension rope 4, ensuring even force distribution. After loading, tightening the tension rope 4 causes the bottom of the bag 1 to contract tightly and close. At this time, the pressing block 11 on the side wall of the fixing block 10, under the elastic force of the return spring 12, tightly abuts against the tension rope 4 through the limiting groove on the side wall, limiting the degree of tightening and preventing it from loosening on its own, ensuring a tight seal at the bottom of the bag 1 and effectively preventing leakage. Furthermore, the bubble cushioning body 6, which is attached to the bottom of the bag 1, adopts a bubble structure and can absorb external impact during transportation, reducing the impact on the items. The impact with the bottom of the bag body 1 provides cushioning protection for the items at the bottom, especially suitable for protecting fragile items. At the same time, the anti-collision block 7, which is made of EVA foam material and has a right-angled trapezoidal structure, can reduce the side impact force and form all-round protection for the items inside the bag, preventing damage to the items due to side collisions. This solves the problem of lack of side protection in FIBCs. Finally, the lifting components on both sides of the top of the bag body 1 facilitate handling. The traction rope 2 is slidably set in the movable hole and the diversion hole of the mounting block on the inner wall of the bag body 1. It is convex and can disperse the tension during handling, avoiding excessive local stress that could damage the bag body 1. For manual handling, the traction rope 2 can provide a convenient point of force application, improving the convenience of handling operations. This concludes the use of the composite PP FIBC with moisture-proof and leak-proof functions.
