Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flood control and dike reinforcement bag manufacturing technology, and in particular refers to a flood control and dike reinforcement bag preparation production line. Background Technology
[0002] Flood control and dike reinforcement bags are important tools specifically designed to cope with natural disasters such as floods and rainstorms. The selection and proper application of these materials directly affect the effectiveness and durability of flood control projects.
[0003] Early flood control and dike reinforcement materials mainly relied on natural resources such as sandbags, timber, and stone. Timber and stone construction required advance planning, while sandbags were primarily used in emergency flood control and breach closure operations. These sandbags used canvas as the outer bag material, which has good water absorption. Sand was manually filled inside, and the bag was tied tightly with rope. This method was effective for flood control and breach closure projects, but the process was cumbersome, production efficiency was low, it required a large amount of manpower, and the sandbags were large and heavy, making them inconvenient to store and transport. With the rise of geosynthetics, geotextiles began to be widely used. These materials have good permeability and filtration properties, effectively preventing soil particle migration while allowing water to pass freely. This characteristic makes them excellent in the construction of filter layers and drainage layers. However, these materials also require advance foundation construction and cannot respond promptly to sudden flood control and breach closure operations.
[0004] However, existing flood control bag manufacturing production lines suffer from the following drawbacks: Low automation: The lack of efficient automated equipment makes the entire production process time-consuming and increases production costs. Unstable quality: Manually cut flood control bags are difficult to keep in consistent size, affecting the reinforcement effect of dikes. Poor sealing: Traditional sealing methods are prone to leaks, causing leakage after the flood control bags are filled, reducing the flood control effect. Serious material waste: It is difficult to ensure uniform filling of materials, and some flood control bags may be underfilled, affecting the flood control effect. Existing flood control bag manufacturing production lines suffer from low production efficiency, unstable quality, serious material waste, and a lack of intelligent management. To solve these problems and improve the efficiency and quality of flood control and dike reinforcement, it is particularly important to develop an automated and intelligent flood control and dike reinforcement bag manufacturing production line.

[0016] Beneficial effects
[0017] This invention provides a production line for manufacturing flood control and dike reinforcement bags. An unwinding device unwinds a continuous sandwich-structure spunbond nonwoven composite material. A cutting device uniformly cuts the material to the required length, and then a folding device folds it in half. The low-melting-point PET layer is placed inside, and the material enters an ultrasonic sealing machine. Under the adhesive effect of ultrasound, a bag shape is formed. Weighed bentonite is fed into the bag, and the opening is sealed by an ultrasonic sealing machine. This simplifies the production process and effectively improves production efficiency. The tight structure of the spunbond composite nonwoven material prevents the bentonite from falling out, while its porous structure allows water to quickly penetrate into the bentonite inside the bag, causing it to expand. This saves storage space and facilitates transportation, making it a promising application for emergency flood control and dike reinforcement.
[0018] Existing flood control and dike reinforcement bags are generally made of canvas or woven bags, requiring sewing beforehand and manual placement onto a bag clamping device. Large quantities of sand and gravel require conveyor belts for transport. After filling, manual sorting is necessary before the bags are sent to a sewing and thread-cutting device for stitching and trimming. The process from canvas or woven material to flood control and dike reinforcement bag is not a one-step process, resulting in low automation, low production efficiency, and the heavy sand and gravel filling places certain demands on the equipment's load-bearing capacity. This production line, however, utilizes a sandwich-structured spunbond nonwoven composite material and bentonite, combined with an ultrasonic edge-sealing machine and a sealing machine, enabling integrated molding from bag material to flood control and dike reinforcement bag. This simplifies equipment, improves production efficiency, and allows a small amount of bentonite to achieve the same effect as a large amount of sand and gravel. It also reduces the load-bearing capacity requirements of the equipment and alleviates subsequent transportation pressure, making it an ideal flood control and dike reinforcement bag production line.

[0029] Example 1
[0030] like Figure 1 As shown, a production line for preparing flood control and dike reinforcement bags includes an unwinding device 1, a cutting device 2, a folding device 3, and an edge sealing device. The unwinding device 1, the cutting device 2, the folding device 3, and the edge sealing device are connected in sequence.
[0031] The unwinding device 1 is located on the far left of the production line. The unwinding device is a frame with mandrel grooves on both sides, with a mandrel hanging horizontally on top. It is 1 meter wide, and the fabric roll is hung on the mandrel. It is used to convey the 60cm wide flood control and dike-stabilizing bags made of continuous spunbond nonwoven composite material to the cutting device 2. The flood control and dike-stabilizing bags are made of continuous spunbond nonwoven composite material such as… Figure 2 As shown; the continuous spunbond nonwoven composite material used for the flood control and dike reinforcement bag is a sandwich-structured spunbond nonwoven composite material, with a low-melting-point PET spunbond layer on top, a glass fiber mesh reinforcement layer in the middle, and a high-melting-point PET spunbond layer on the bottom.
[0032] The cutting device 2 is used to cut the continuous spunbond nonwoven composite material used for flood control and dike reinforcement bags into sheet materials. The cutting device 2 is equipped with a cross-cutting blade, which is pneumatically controlled. The blade quickly descends to cut and then rises, uniformly cutting the spunbond nonwoven composite material into sheet materials 100cm to 200cm long, preferably 160cm. The sheet materials are as follows... Figure 3 As shown.
[0033] The folding device 3 is used to fold the cut sheet material in half. The front end of the folding device 3 is equipped with a gripper and a sensor. When the composite material is detected moving to the gripper position, the gripper grips both ends of the material downwards and slowly lifts it up. Simultaneously, small pressure rods extend from the fold line position to both sides of the material, pressing down on the sides of the material by 5cm and moving forward with the mesh curtain and the material. When a set distance is reached, the gripper drops and releases the material. After the material is folded, the pressure rods retract to both sides. The folding method is along... Figure 4 Folding along the dotted line in the diagram yields a double-layer spunbond nonwoven composite material with a low-melting-point PET spunbond layer on the inside and a high-melting-point PET spunbond layer on the outside. The double-layer spunbond nonwoven composite material with a low-melting-point PET spunbond layer on the inside and a high-melting-point PET spunbond layer on the outside is as follows: Figure 5 As shown.
[0034] The edge-sealing device includes an ultrasonic edge-sealing machine 5 and an ultrasonic sealing machine 9. A conveyor curtain 4 is provided between the folding device 3 and the ultrasonic edge-sealing machine 5. The conveyor curtain 4 is used to convey a double-layer spunbond nonwoven composite material with a low-melting-point PET spunbond layer inside and a high-melting-point PET spunbond layer outside to the ultrasonic edge-sealing machine 5 for edge-sealing. A shock-absorbing device is installed parallel to the bottom of the conveyor curtain 4 to prevent vibration during transmission. The conveyor curtain 4 is equipped with a continuous conveyor belt with a closed-loop structure. Multiple evenly distributed guide sliders are provided on the inner surface of the continuous conveyor belt. These guide sliders extend along the running direction of the continuous conveyor belt, ensuring the smooth operation of the conveyor belt and effectively reducing noise and wear during operation.
[0035] The ultrasonic edge-sealing machine 5 is used to seal both sides of a double-layer spunbond nonwoven composite material to form a bag-shaped structure with one open end. The bag-shaped structure is as follows: Figure 6 As shown. The output side of the ultrasonic sealing machine 5 is connected to the bentonite filling area, which is equipped with a bentonite conveying pipe 6. The bag-shaped spunbond nonwoven composite material is fed into the bentonite filling area with its opening tilted upwards at 10-15°. The weighed bentonite is slowly fed into the bag through the bentonite conveying pipe 6. Then, the bentonite conveying pipe 6 exits the filling area, and the bag-shaped spunbond nonwoven composite material filled with bentonite is fed into the ultrasonic sealing machine 9 for sealing, thus obtaining a flood control and dike-stabilizing bag. Figure 7 As shown.
[0036] A transfer curtain 7 and a transition curtain 8 are provided between the ultrasonic edge sealing machine 5 and the ultrasonic sealing machine 9. The transfer curtain 7 is inclinedly positioned on the output side of the ultrasonic edge sealing machine 5 and connected to the transition curtain 8; the angle between the transfer curtain 7 and the transition curtain 8 is 100~170°. The transfer curtain 7 is positioned below the bentonite conveying pipe 6, and the transition curtain 8 is used to adjust the output direction and bag opening orientation of the bag-shaped spunbond nonwoven composite material containing bentonite.
