A moisture-proof and breathable valve pocket

Abstract

This utility model provides a moisture-proof and breathable valve bag, relating to the field of valve bag technology. It includes a valve bag with a base fixedly installed at the bottom of its outer surface. Two support frames are fixedly installed on both sides of the outer surface of the base. Two bidirectional screws are rotatably installed at the other ends of the four support frames. Four connecting blocks are fixedly installed on the upper side of the outer surface of the bidirectional screws. The four connecting blocks are threaded onto the outer surface of the two bidirectional screws. Two sliding rods are slidably arranged at the bottom of the four connecting blocks. The two ends of the two sliding rods are fixedly installed on the outer surface between the four support frames. A knob is fixedly installed at one end of each of the two bidirectional screws. Because the connecting blocks are limited by the bottom sliding rods, the rotation of the bidirectional screws can drive the four connecting blocks to move. Since the four connecting blocks are fixedly installed at the four corners of the valve bag, moving the connecting blocks to the sides can tighten the top of the valve bag, thereby closing the valve bag's inlet and preventing the valve bag from collapsing.

Description

Technical Field

[0001] This utility model relates to the field of valve bag technology, and in particular to a moisture-proof and breathable valve bag. Background Technology

[0002] Valve bags are packaging bags with special filling openings, mainly used for packaging and transporting powdery and granular materials (such as cement, fertilizer, feed, and chemical raw materials). Their core features are high automated filling efficiency and good sealing performance, and they are widely used in the industrial, agricultural, and construction industries.

[0003] A search revealed Chinese Patent No. CN 215206216 U, which discloses a breathable valve bag. The bag includes a bag body with a horizontally mounted mounting plate on its lower end face. Two support plates are hinged to the lower end face of the mounting plate, and two limiting blocks are provided on the mounting plate. The two support plates are located between the two limiting blocks, and the limiting blocks are designed to abut against the corresponding support plates after they are flipped. This invention has the following advantages and effects: by using two support plates to support the mounting plate and the bag body, and ensuring that the bag body is isolated from the ground when stored, it effectively prevents water stains or moisture from entering the bag body, thereby preventing the product inside the bag from getting damp, thus improving the moisture-proof capability of the valve bag.

[0004] The aforementioned technology utilizes two support plates to support the mounting plate and the bag body, ensuring that the bag body is isolated from the ground during storage. This effectively prevents water stains or moisture from entering the bag body, thereby preventing the product inside the bag from becoming damp. However, the technology still has certain shortcomings. Since valve bags are usually made of polypropylene (PP) or polyethylene (PE) plastic, although these materials have advantages such as being lightweight and durable, they have obvious defects when storing materials that are not fully used. As the material inside the bag gradually decreases, the characteristics of the plastic material cause the bag body to lack sufficient support. Under external pressure or stacked storage, it is very easy to soften and deform. This softening phenomenon will directly damage the sealing performance of the valve bag, making it impossible for the valve designed for moisture prevention to close tightly, causing moisture and impurities in the outside air to continuously seep into the bag.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a moisture-proof and breathable valve bag, comprising: a valve bag 101, a base 102 fixedly installed on the bottom of the outer surface of the valve bag 101, two support frames 103 fixedly installed on both sides of the outer surface of the base 102, two bidirectional screws 104 rotatably installed on the other end of the four support frames 103, four connecting blocks 105 fixedly installed on the upper side of the outer surface of the bidirectional screws 104, the four connecting blocks 105 being threadedly installed on the outer surface of the two bidirectional screws 104 respectively, two sliding rods 116 being slidably arranged at the bottom of the four connecting blocks 105, the two ends of the two sliding rods 116 being fixedly installed on the outer surface between the four support frames 103 respectively, and a knob 106 fixedly installed on one end of each of the two bidirectional screws 104.

[0032] like Figure 1 - Figure 4 As shown, two connecting rods 107 are fixedly installed between the four support frames 103. The connecting rods 107 can support the support frames 103 on both sides, thereby improving the stability of the device.

[0033] like Figure 1 - Figure 4 As shown, handles 108 are fixedly installed on the upper side of the two connecting rods 107. By setting handles 108, the valve bag 101 can be taken out, improving convenience.

[0034] like Figure 1 - Figure 4 As shown, a valve port 109 is fixedly installed on one side of the outer surface of the valve bag 101. A silicone 110 is installed at one end of the valve port 109. The silicone 110 can absorb moisture and prevent moisture from entering the valve bag 101 through the valve port 109.

[0035] like Figure 1 - Figure 4 As shown, a support leg 113 is fixedly installed on the bottom of the base 102, and four rubber pads 115 are installed on the bottom of the support leg 113, which effectively improves the stability of the device.

[0036] like Figure 1 - Figure 4As shown, the support leg 113 has a ventilation hole 114 inside, which can improve the air permeability of the valve pocket 101.

[0037] like Figure 1 - Figure 4 As shown, an aluminum-plated film 112 is fixedly installed on the inner surface of the valve bag 101. By setting the aluminum-plated film 112, water vapor and oxygen can be isolated.

[0038] like Figure 1 - Figure 4 As shown, the outer surface of the valve bag 101 is coated with graphene 111, which can improve moisture resistance without affecting breathability.

[0039] Working principle: In use, the device is first placed on a stable ground for storage via the support leg 113. When the material inside the valve bag 101 is not completely used, the knob 106 at one end of the two bidirectional screws 104 needs to be manually turned to drive the bidirectional screws 104 to rotate. Since the connecting block 105 on the outer surface of the bidirectional screw 104 is limited by the bottom slide rod 116, the rotation of the bidirectional screw 104 can drive the four connecting blocks 105 to move. Since the four connecting blocks 105 are fixedly installed at the four corners of the valve bag 101, moving the connecting blocks 105 to both sides can tighten the top of the valve bag 101, thereby closing the feed port of the valve bag 101 and preventing the valve bag 101 from collapsing. At this time, the silicone 110 on one side of the valve port 109 can effectively absorb moisture. The vent hole 114 at the bottom of the support leg 113 can also improve the air permeability of the valve bag 101 and prevent the valve bag 101 from getting damp.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or equivalent variations to the above-disclosed technical content and apply them to other fields. However, any simple modifications, equivalent variations and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
