[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 As shown:

[0022] This utility model provides an environmentally friendly composite stabilizer powder bag weighing device, including a base 1, a support seat 2, a housing 3, a weighing column 4, a support platform 5, a ball screw 6, a drive component 7, a ball nut 8, a lifting frame 9, a lifting slot 10, a lifting platform 11, a side plate 12, a conveyor belt 13, and a conveyor motor 14. The support seat 2 and the housing 3 are fixedly installed adjacent to each other on the base 1. The support seat 2 is connected to the support platform 5 through the weighing column 4. The support seat 2 is located on the lower side of the housing 3. The ball screw is rotatably installed inside the housing 3. The upper end of 6 is fixed to the output end of the drive component 7 fixedly installed on the upper part of the outer casing 3; a lifting frame 9 is fixedly installed on the ball nut 8 installed on the ball screw 6, and the two ends of the lifting frame 9 extend outward through the lifting slot 10 opened in the casing 3, and the lifting platform 11 is placed thereon. Conveying rollers are rotatably installed on the two side plates 12 fixedly installed on the lifting platform 11, and conveying belts 13 are assembled on the conveying rollers. One of the conveying rollers is fixed to the output end of the conveying motor 14 fixedly installed on the outer part of one of the side plates 12.

[0023] Furthermore, the support base 2, weighing column 4, and support platform 5 constitute a precision weighing mechanism. The support base 2 is made of high-strength stainless steel and is bolted to the base 1, its stable support structure providing the foundation for the entire weighing system. The weighing column 4 is made of alloy steel, and its internal structure integrates a high-precision strain gauge load cell. This load cell is protected through a potting process, providing excellent anti-interference and waterproof / dustproof performance. The upper and lower ends of the weighing column 4 are bolted to the support base 2 and support platform 5 respectively via flanges, ensuring stable force transmission. The support platform 5 is a rectangular flat plate structure with an anti-slip surface. Its area is designed to fully accommodate the stable placement of the lifting platform 11, supporting the lifting platform 11 and the powder bags above it. The load cell accurately measures the weight of the powder bags by detecting the pressure on the support platform 5.

[0024] Furthermore, the support platform 5 is positioned directly below the lifting platform 11 and the lifting frame 9. The lifting frame 9 adopts a U-shaped steel structure, welded from high-strength square tubing, possessing sufficient rigidity and stability. Both ends of the lifting frame 9 slide against the lifting slots 10 in the housing 3 via guide rails, allowing for smooth vertical lifting and lowering driven by the ball screw 7. The precise spacing between the two extended ends of the lifting frame 9 forms a clearance area for the support platform 5. This area is slightly larger than the overall dimensions of the support platform 5, ensuring that the lifting frame 9 does not interfere with the support platform 5 during lifting, and allowing the lifting platform 11 to smoothly descend onto the support platform 5 for weighing.

[0025] Further, the bottom of the lifting platform 11 is provided with a groove matching the shape of the extended outer end of the lifting frame 9. The depth of the groove is precisely calculated to ensure that the lifting platform 11 can be stably placed without shaking after the outer end of the lifting frame 9 is embedded in the groove. The lifting platform 11 is made of lightweight high-strength aluminum alloy material, and the surface is treated by anodic oxidation, which not only reduces the overall weight, but also improves the wear resistance and corrosion resistance. The side plate 12, the conveying belt 13 and the conveying motor 14 fixedly installed on the lifting platform 11 together constitute the powder bag conveying mechanism. The side plate 12 is a rectangular plate structure, which is fixed on both sides of the lifting platform 11 by bolts, and its material is the same as that of the lifting platform 11 to ensure the structural strength and corrosion resistance. Two conveying rollers are rotatably installed on the side plate 12 through bearings, and the conveying belt 13 is sleeved on the outer surfaces of the two conveying rollers and is kept at an appropriate tension by a tensioning device. The conveying motor 14 is a servo motor connected to the shaft end of one of the conveying rollers through a coupling, which can accurately control the running speed and start-stop of the conveying belt 13 to ensure stable conveying of the powder bag.

[0026] Further, the conveying belt 13 assembled by the two conveying rollers of the side plate 12 is accurately positioned directly below the discharge port of the packaging equipment, and its position is accurately calibrated to ensure that the powder bag can directly fall onto the conveying belt 13 after packaging is completed. The conveying belt 13 is made of food-grade rubber material and has anti-slip texture on the surface, which can effectively prevent the powder bag from sliding during conveying and meet the requirements of environmental protection production. One end of the conveying belt 13 is designed with a transition slope, which can guide the powder bag to smoothly transition to the production line belt when the conveying belt 13 is connected to the belt conveying system of the production line, avoiding the powder bag from being stuck or falling at the junction. The width of the conveying belt 13 matches the width of the belt of the belt conveying system of the production line to ensure the continuity and stability of the powder bag conveying.

[0027] Further, one end of the drag chain 15 is fixedly connected to the outside of the side plate 12, and the other end of the drag chain 15 is fixed to the side of the machine shell 3 through a mounting bracket. The drag chain 15 is made of engineering plastic material and has good flexibility and wear resistance, and the connecting line inside the drag chain 15 is used to connect the conveying motor 14 fixedly installed on the side plate 12 with the control system of the equipment. During the lifting process of the lifting frame 9, the lifting platform 11 and the side plate 12, the drag chain 15 can protect and guide the connecting line to prevent the connecting line from being pulled, worn or tangled during movement, ensuring the stability of the control signal and power supply of the conveying motor 14 and the normal operation of the powder bag conveying mechanism.

[0028] The working principle is as follows: First, the opening of the powder bag is placed on the discharge port of the packaging equipment, and the two are fixed by the fixing mechanism. Start the packaging equipment, and the environmental protection composite stabilizer powder is injected into the powder bag through the discharge port. When the powder filling reaches the set amount, the packaging equipment stops conveying.

[0029] Next, the drive unit 7 starts, and its output end drives the ball screw 6 inside the housing 3 to rotate. The ball screw 6 cooperates with the ball nut 8 to convert the rotational motion into linear motion, causing the ball nut 8 to move upward along the ball screw 6, thereby driving the lifting frame 9 fixed on the ball nut 8 to rise synchronously. The two ends of the lifting frame 9 move smoothly upward along the guide rail through the lifting slots 10, and its "U"-shaped outer end is embedded in the groove at the bottom of the lifting platform 11, lifting the lifting platform 11 and the powder bag conveying mechanism together.

[0030] Subsequently, the lifting frame 9 continues to rise until the conveyor belt 13 on the lifting platform 11 contacts the bottom of the powder bag. After injection, the fixing mechanism releases its constraint on the powder bag and discharge pipe. Under the action of contact force, the powder bag falls from the discharge pipe of the packaging equipment and is placed on the conveyor belt 13. At this time, the drive component 7 reverses, and the ball screw 6 drives the lifting frame 9 to move downward, and the lifting platform 11 and the powder bag descend accordingly. When the lifting platform 11 lands smoothly on the bearing platform 5, the lifting frame 9 continues to descend, and its outer end disengages from the bottom groove of the lifting platform 11, completing the transfer of the powder bag.

[0031] Then, the high-precision strain gauge load cell inside the weighing column 4 below the support platform 5 starts to work. By detecting the pressure on the support platform 5, it accurately measures the weight of the powder bag and transmits the weight data to the equipment control system for processing and display.

[0032] Finally, after weighing, the conveyor motor 14 starts, driving one of the conveyor rollers to rotate via a coupling, which in turn drives the conveyor belt 13. The anti-slip texture on the surface of the conveyor belt 13 contacts the powder bag, causing it to move along the conveying direction. Because one end of the conveyor belt 13 has a transition slope and is precisely connected to the belt conveyor system of the production line, the powder bag can smoothly transition onto the belt of the production line and be transported to subsequent processes for packaging or storage. During this process, the drag chain 15 connected to the outside of the side plate 12 extends and retracts flexibly with the lifting platform 11, effectively protecting the internal connecting wires, ensuring the stability of the control signal and power supply of the conveyor motor 14, and guaranteeing the continuity of powder bag conveying.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
