Description

TECHNICAL FIELD

[0001] The utility model relates to valve bag technical field, concretely is valve bag with two hot melt adhesives. BACKGROUND

[0002] Valve bag, also known as bottom paste bag, is a common packaging bag. Its bag mouth design is unique, with a structure similar to a valve. This bag is usually made of multiple layers of material, and common materials include kraft paper, plastic woven cloth, etc. Different materials give it different properties. For example, kraft paper valve bags have good toughness and certain moisture resistance; plastic woven valve bags are more durable and resistant to wear. Valve bags are widely used in industrial and agricultural fields. In the chemical industry, they are used to package various powdery and granular chemical raw materials, effectively preventing material leakage and the mixing of external impurities; they also perform well in the packaging of agricultural products such as grain and feed, protecting product quality. The loading process is relatively convenient, with material loaded from the valve, the valve automatically closed after filling, reducing the manual sealing step and improving packaging efficiency. When unloading, you only need to open the corresponding part to smoothly pour out the material. Due to its good practicality and convenience, valve bags have become an indispensable part of the packaging process in many industries.

[0003] After the valve bag is filled with material, the inlet sleeve is usually closed by a hot melt adhesive ring to ensure internal sealing and prevent material from spilling from the inlet sleeve. However, after the valve bag is filled with material, the factory will accumulate a large number of filled valve bags, causing the inlet sleeve to be squeezed, which can cause the internal hot melt adhesive ring to detach from the inlet sleeve under prolonged pressure, resulting in material leakage. INVENTION CONTENTS

[0004] To solve the above technical problems, the utility model provides a valve bag with two hot melt adhesives, which includes a valve bag body, a feeding sleeve is fixedly connected to the left end of the valve bag body, a hot melt adhesive ring is fixedly connected to the inner wall of the feeding sleeve, a magic tape wool surface is fixedly connected to the bottom of the feeding sleeve, a magic tape thorn surface is fixedly connected to the left end of the valve bag body, and a reinforcing layer is fixedly connected to the inner wall of the valve bag body.

[0005] Through the above technical solution, by setting the magic tape wool surface and the magic tape thorn surface, after the internal material of the valve bag body is filled, the hot melt adhesive ring closes the inlet of the feeding sleeve, and then the magic tape wool surface is adhered to the surface of the magic tape thorn surface, so that the feeding sleeve is attached to the surface of the valve bag body, ensuring that the feeding sleeve is tightened during transportation or placement, avoiding squeezing, and preventing the internal hot melt adhesive ring from detaching from the inner wall of the feeding sleeve during squeezing, causing leakage.

[0006] As a further improvement to the above solution, two hot melt adhesive rings are provided, and the two hot melt adhesive rings are symmetrically and evenly distributed on the inner wall with respect to the top center of the feed cuff.

[0007] By using the above technical solution, two hot melt adhesive rings are set and symmetrically and evenly distributed on the inner wall around the top center of the feed sleeve, which can better ensure the sealing effect of the feed sleeve and prevent material leakage.

[0008] As a further improvement to the above solution, the reinforcing layer is located at the top and bottom of the inner wall of the valve pocket body.

[0009] With the above technical solution, the reinforcing layer is located at the top and bottom of the inner wall of the valve bag body. This layout can play a good role in strengthening the overall structure of the valve bag and improving the durability of the bag.

[0010] As a further improvement to the above solution, the reinforcing layer is made of polyethylene.

[0011] Through the above technical solution, the reinforcing layer material is polyethylene, which has good flexibility, corrosion resistance and other properties, and can effectively extend the service life of the valve bag.

[0012] As a further improvement to the above solution, a fixed base is fixedly connected to the top of the valve bag body, a fixed side plate is fixedly connected to the top of the fixed base, a fixed column is fixedly connected to the surface of the fixed side plate, a movable sleeve is rotatably connected to the surface of the fixed column, and a handle is fixedly connected to the surface of the movable sleeve.

[0013] The above technical solution, with its fixed base, fixed side plate, fixed column, movable sleeve, and handle on the top of the valve bag body, facilitates operation of the valve bag, such as handling or hanging.

[0014] As a further improvement to the above solution, two fixed side plates are provided, and the two fixed side plates are symmetrically and evenly distributed around the top center of the fixed base.

[0015] By using the above technical solution, two fixed side plates are set up that are symmetrically and evenly distributed around the top center of the fixed base, making the structure more stable and better supporting the connected components, thus ensuring the stability of the entire device.

[0016] As a further improvement to the above solution, the number of movable sleeves is set to two, and the two movable sleeves are evenly distributed symmetrically around the center of the bottom of the handle.

[0017] Through the above technical solution, two movable sleeves that are symmetrically and evenly distributed around the center of the bottom of the handle make the handle more evenly stressed during operation, making it easier to lift or move the valve bag stably.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention utilizes a combination of hook and loop fasteners, with a rough surface and a barbed surface. After the valve bag body is filled with material, a hot melt adhesive ring seals the feed inlet of the feed sleeve. The rough surface of the hook and loop fastener is then bonded to the surface of the barbed surface, ensuring that the feed sleeve adheres to the surface of the valve bag body. This ensures that the feed sleeve is tightened during transportation or placement, preventing accumulation and compression that could cause the internal hot melt adhesive ring to detach from the inner wall of the feed sleeve during compression, thus preventing leakage. The two layers of hot melt adhesive rings provide a more complete seal for the surface of the feed sleeve.

[0020] This utility model features a handle that is fixedly connected to the surface of a movable sleeve, which is rotatably connected to the surface of a fixed post, making it easy to carry when using the valve bag body. Attached Figure Description
