[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A continuous powder filling and weighing device includes a base plate 6, a roller conveyor 1, a double belt conveyor 2, a weighing platform 3, a lifting and transferring mechanism 4, and a dual-station feeding mechanism 5. The weighing station is located at the middle of the upper end of the base plate 6; the transferring stations are located on the front and rear sides of the upper right side of the base plate 6.

[0035] A weighing platform 3 is fixedly installed at the upper middle part of the base plate 6;

[0036] A dual-station feeding mechanism 5 is installed at the upper middle part of the bottom plate 6 to control the movement of the tank between the weighing station and the material transfer station;

[0037] The dual-station feeding mechanism 5 is equipped with a lifting and transferring mechanism 4 for controlling the movement and lifting of the tank to perform weighing operations;

[0038] The lifting and transferring mechanism 4 includes a movable component 42 for moving the double belt conveyor 2 and a drive component 41 for controlling the movement of the movable component 42; both the drive component 41 and the movable component 42 are mounted on the dual-station feeding mechanism 5; the drive component 41 and the movable component 42 are connected to the double belt conveyor 2.

[0039] Two material-stopping cylinders 7 are installed on the movable component 42;

[0040] A roller conveyor 1 is installed on the left side of the weighing station; a roller conveyor 1 is installed at each of the two material transfer stations; and the roller conveyors 1 are all fixedly installed on the upper end of the base plate 6.

[0041] The width of the double belt conveyor 2 is greater than the width of the weighing platform 3;

[0042] A powder filling machine 8 is fixedly installed on the upper rear side of the base plate 6;

[0043] The discharge pipe of the powder filling machine 8 is fixedly equipped with a baffle 9;

[0044] A suction pipe 10 is also fixedly installed at the outer end of the discharge pipe of the powder filling machine 8; the suction pipe 10 is connected to the inside of the discharge pipe of the powder filling machine 8 and the inside of the baffle 9; the outside of the suction pipe 10 is connected to the air pump.

[0045] The diameter of the baffle 9 is larger than the diameter of the tank inlet;

[0046] In this utility model, in the initial state, the double belt conveyor 2 is located between the roller conveyor 1 on the left side of the weighing station and the roller conveyor 1 on the rear side of the material transfer station; and the height of the upper end face of the double belt conveyor 2 is the same as the height of the roller conveyor 1.

[0047] Since the tanks need to be cleaned and dried before filling and weighing, and the cleaning and drying process takes a long time, while the powder filling process takes a short time; when the filling and weighing operation begins, the cleaned and dried tanks can be alternately placed on the roller conveyor 1 at the front and rear material transfer station for conveying.

[0048] When the tank is placed on the roller conveyor 1 at the rear transfer station, the roller conveyor 1 at the rear transfer station drives the tank to move to the left towards the weighing station until the tank moves onto the double belt conveyor 2. At this point, the material blocking cylinders 7 on both sides work to limit the movement of the tank. Then, the drive assembly 41 works to drive the double belt conveyor 2 to move downwards following the movable assembly 42. During the movement, since the width of the double belt conveyor 2 is greater than the width of the weighing platform 3, the double belt conveyor 2 will pass through the weighing platform 3 and drive the tank to continue moving downwards until the lower end of the tank contacts the upper end of the weighing platform 3. At this point, the tank is transferred from the double belt conveyor 2 to the upper end of the weighing platform 3.

[0049] Subsequently, the powder filling machine 8 operates, driving the baffle 9 downwards until it covers the inlet of the tank at the weighing station. The powder filling machine 8 then fills the tank with powder. During the filling process, the weighing platform 3 monitors the weight of the tank in real time. The powder filling machine 8 stops operating when the weight reaches the set value. Then, the air pump outside the suction pipe 10 sucks out the dust that has accumulated on the baffle 9 and the discharge pipe of the powder filling machine 8, preventing dust from escaping when the baffle 9 separates from the tank after filling. Next, the drive assembly 41 drives the double belt conveyor 2 to reset upwards along the movable assembly 42, lifting the tank placed on the weighing platform 3 and returning it to the top of the double belt conveyor 2. Then, the baffle cylinders 7 on both sides reset, and the double belt conveyor 2 moves the filled tank to the roller conveyor 1 on the left side of the weighing station. The roller conveyor 1 then moves the tank to the left for the next production step.

[0050] When the tank is placed on the roller conveyor 1 at the front transfer station, the dual-station feeding mechanism 5 will work to drive the drive assembly 41, the moving assembly 42 and the dual belt conveyor 2 to move forward as a whole until the dual belt conveyor 2 is aligned with the roller conveyor 1 at the front transfer station; then the roller conveyor 1 at the front transfer station will work to move the tank onto the dual belt conveyor 2, and then the dual-station feeding mechanism 5 will drive the tank back to the weighing station for powder filling and weighing.

[0051] By repeating the above steps, continuous powder filling and weighing operations can be achieved in the tank.

[0052] By cooperating with the drive component 41, the moving component 42, and the weighing platform 3, the device eliminates the need for additional clamping or lifting devices to place the tanks on the weighing module for weighing operations. This reduces the time spent on actions such as clamping, shifting, and resetting the tanks, increasing production capacity and improving the device's practicality in the same amount of time. Furthermore, during weighing, only the tanks are in contact with the weighing platform 3, ensuring weighing accuracy. The dual-station feeding mechanism 5 enables the device to perform continuous powder filling and weighing operations on the tanks, avoiding the extra time consumed by waiting for pre-processing steps such as cleaning and drying the tanks, further enhancing the device's practicality.

[0053] like Figures 1-4 As shown, the dual-station feeding mechanism 5 includes a horizontal guide rail 51, a horizontal sliding block 52, a fixed rack 53, a drive gear 54, a drive motor 55, and a U-shaped moving plate 56. The horizontal guide rail 51 is symmetrically fixedly installed on the left and right sides of the upper middle part of the base plate 6; the horizontal sliding block 52 is slidably connected to the horizontal guide rail 51; the U-shaped moving plate 56 is fixedly installed on the upper end of the horizontal sliding block 52; and the fixed rack 53 is fixedly installed on the upper right side of the base plate 6.

[0054] The drive gear 54 is rotatably mounted on the lower right side of the U-shaped moving plate 56; the drive gear 54 is meshed with the fixed rack 53; the drive motor 55 is fixedly mounted on the upper right side of the U-shaped moving plate 56; and the output end of the drive motor 55 is fixedly connected to the drive gear 54.

[0055] The width of the U-shaped moving plate 56 is greater than the width of the weighing platform 3;

[0056] like Figures 1-4 As shown, the drive assembly 41 includes a push cylinder 411, a push block 412, a push rod 413, a drive sprocket 414, and a chain 415. The push cylinder 411 is fixedly installed on the upper front side of the U-shaped moving plate 56; the output end of the push cylinder 411 is fixedly connected to the push block 412; push rods 413 are symmetrically fixedly installed on both the left and right ends of the push block 412; the drive sprocket 414 is rotatably installed on the outer end of the push rod 413; the chain 415 is wound around the outer end of the drive sprocket 414; one end of the chain 415 is fixedly connected to the front end of the double belt conveyor 2; the other end of the chain 415 is fixedly connected to the upper end of the U-shaped moving plate 56; the drive sprocket 414 is meshed with the chain 415.

[0057] like Figures 1-4 As shown, the movable component 42 includes a vertical guide rail 421, a sliding block 422, and a U-shaped upright plate 423. The U-shaped upright plate 423 is fixedly installed on the upper rear side of the U-shaped moving plate 56. The vertical guide rail 421 is symmetrically fixedly installed on the left and right sides of the front end of the U-shaped upright plate 423. The sliding block 422 is limited and slidably connected to the vertical guide rail 421. The sliding block 422 is fixedly connected to the rear end of the double belt conveyor 2.

[0058] The upper height of the U-shaped vertical plate 423 is higher than the upper height of the weighing platform 3;

[0059] The material-stopping cylinder 7 is symmetrically and fixedly installed on the rear side of the U-shaped vertical plate 423;

[0060] In this utility model, when the weighing operation begins, the push cylinder 411 works to drive the push block 412 to move downward. When the push block 412 drives the push rod 413 to move downward, the drive sprocket 414 moves downward together with the push rod 413. At this time, the drive sprocket 414 rotates and pulls the chain 415 to drive the double belt conveyor 2 to move downward along the vertical guide rail 421 following the sliding block 422.

[0061] During the movement, since the width of the double belt conveyor 2 is greater than the width of the weighing platform 3, the double belt conveyor 2 will pass through the weighing platform 3 and drive the tank to continue moving downwards until the lower end of the tank contacts the upper end of the weighing platform 3. At this time, the tank is transferred from the double belt conveyor 2 to the upper end of the weighing platform 3. Then the tank can be filled with powder and weighed.

[0062] After the powder filling is completed, the pusher cylinder 411 pushes the pusher block 412 to reset upward, so that the double belt conveyor 2 resets upward along the vertical guide rail 421, lifts the tank placed on the weighing platform 3, and moves the tank back to the top of the double belt conveyor 2.

[0063] When the tank is placed on the roller conveyor 1 at the front transfer station, the drive motor 55 drives the drive gear 54 to rotate, and under the action of the fixed rack 53, the U-shaped moving plate 56 moves forward along the horizontal guide rail 51 following the horizontal sliding block 52 until the double belt conveyor 2 is aligned with the roller conveyor 1 at the front transfer station.

[0064] Subsequently, the roller conveyor 1 at the front material transfer station moves the tank onto the double belt conveyor 2, and the drive motor 55 drives the tank to move backward to the weighing station for powder filling and weighing.

[0065] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
