Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a quantitative feeding and filling device. Background Technology

[0002] When powder coatings are bagged, a bagging mechanism with a weighing hopper is used to achieve quantitative bagging, thereby ensuring that the amount of each bag is consistent, which can improve bagging efficiency and measurement accuracy, and reduce material waste and labor costs.

[0003] After powder coating is bagged, it is conveyed to the sealing equipment for automatic sealing. However, due to uneven stress during the filling process, the powder accumulates inside the bag, causing the center of gravity to shift. This results in the bag opening being squeezed and deformed. If not addressed promptly, the bag will shift position while running on the conveyor, making it difficult to accurately align with the sealing machine. This leads to a crooked seal, poor sealing, and even leakage. Therefore, after the coating is bagged, the bag opening needs to be manually readjusted before a new bag can be placed on the unloading equipment, which reduces overall efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative feeding and filling device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quantitative feeding and filling device includes an equipment platform and a conveyor. A distributing hopper is fixedly installed on the equipment platform, and two weighing hoppers are also fixedly installed on the equipment platform below the distributing hoppers. A discharging hopper is fixedly installed at the bottom of the equipment platform, and a discharging valve is fixedly installed at the lower end of the discharging hopper. The discharging valve and the weighing hopper are electrically connected to an external main controller via cables. The conveyor is located below the discharging hopper. Multiple baffles are fixedly installed on both sides of the top of the conveyor. A proximity switch is fixedly installed on one of the baffles. The conveyor and the proximity switch are electrically connected to an external main controller via cables. A bag opening calibrator is also provided on the conveyor between the two baffles. The bag opening calibrator includes two brackets, which are fixedly installed on one side of the conveyor. A rotating frame is movably installed between the two brackets. Fixed rods are fixedly installed on both sides of the rotating frame. A first push rod and a second push rod are respectively inserted into the fixed rods. An axle is fixedly connected between the two second push rods. Multiple rollers are rotatably installed on the outside of the axle.

[0007] As a further preferred embodiment of this utility model, bearing seats are fixedly installed on one side of each of the two brackets, and limit blocks are fixedly installed on the opposite side of each of the two brackets. The bearing seats can provide more stable rotation conditions for the rotating frame, while the limit blocks can limit the angle of free downward swing of the rotating frame.

[0008] As a further preferred embodiment of this utility model, a rotating shaft is fixedly installed on both sides of the rotating frame, and one end of the rotating shaft passes through one of the brackets and is rotatably installed in the corresponding bearing seat.

[0009] As a further preferred embodiment of this utility model, a carrier plate is fixedly installed inside the rotating frame located below the fixed rod, and a cylinder is fixedly installed at the bottom of the carrier plate. The cylinder is connected to an external air pump through an air pipe, and the cylinder provides power for the movement of the two sets of first push rods and second push rods.

[0010] As a further preferred embodiment of this utility model, a sliding groove is provided on the inner side of the fixing rod.

[0011] As a further preferred embodiment of this utility model, a connecting plate is fixedly connected between the two first push rods. The middle part of the connecting plate is fixedly connected to one end of the piston rod of the cylinder. A compression spring is fixedly connected between the first push rod and the second push rod. The compression spring is connected between the first push rod and the second push rod and inserted into the fixed rod. With the cooperation of the cylinder and the connecting plate, the two sets of first push rods and second push rods can move synchronously in the corresponding fixed rods. This allows the roller on the outside of the wheel axle to abut against the bag opening and makes the rotating frame rotate adaptively. This flattens the bag opening from bottom to top, making it easier for the bag opening to enter the sealing machine for sealing.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a bag opening calibrator is set on each side of the conveyor. The bag opening calibrator is composed of a bracket, a rotating frame, a fixed rod, a first push rod, a second push rod, a roller, a cylinder, and other structures. It works in conjunction with a proximity switch on the baffle to start and stop the conveyor, thereby achieving a smoothing action from bottom to top on both sides of the bag opening. No manual intervention is required, and the bag opening can be automatically smoothed, improving the sealing quality of the bag opening. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5 As shown, this utility model provides a quantitative feeding and filling device, including a device platform 1 and a conveyor 5. A distribution hopper 2 is fixedly installed on the device platform 1, and two weighing hoppers 3 are also fixedly installed on the device platform 1 below the distribution hopper 2. A discharge hopper 4 is fixedly installed at the bottom of the device platform 1, and a discharge valve is fixedly installed at the lower end of the discharge hopper 4. The discharge valve and the weighing hopper 3 are electrically connected to an external main controller via cables. The conveyor 5 is located below the discharge hopper 4, and multiple baffles 6 are fixedly installed on both sides of the top of the conveyor 5. One of the baffles 6 is also fixedly installed with a near- The conveyor 5 and the proximity switch 7 are electrically connected to the external main controller via cables. The conveyor 5 located between the two baffles 6 is also equipped with a bag opening calibrator 8. The bag opening calibrator 8 includes two brackets 9, which are fixedly installed on one side of the conveyor 5. A rotating frame 10 is movably installed between the two brackets 9. Fixed rods 11 are fixedly installed on both sides of the rotating frame 10. A first push rod 12 and a second push rod 13 are respectively inserted into the fixed rods 11. A wheel axle 14 is fixedly connected between the two second push rods 13. Multiple rollers 15 are rotatably installed on the outside of the wheel axle 14.

[0022] like Figures 2-3 As shown, bearing seats 16 are fixedly installed on one side of each of the two brackets 9, and limit blocks 22 are fixedly installed on the opposite side of each of the two brackets 9. The bearing seats 16 can provide more stable rotation conditions for the rotating frame 10, while the limit blocks 22 can limit the angle of free downward swing of the rotating frame 10.

[0023] like Figures 2-5 As shown, rotating shafts 17 are fixedly installed on both sides of the rotating frame 10. One end of the rotating shaft 17 passes through one of the brackets 9 and is rotatably installed in the corresponding bearing seat 16. A carrier plate 18 is fixedly installed inside the rotating frame 10 located below the fixed rod 11. A cylinder 19 is fixedly installed at the bottom of the carrier plate 18. The cylinder 19 is connected to an external air pump through an air pipe. The cylinder 19 provides the moving power for the two sets of first push rods 12 and second push rods 13. A sliding groove is opened on the inner side of the fixed rod 11. A connecting plate 20 is fixedly connected between the two first push rods 12. The middle position of the connecting plate 20 is connected to the cylinder 19. One end of the piston rod is fixedly connected, and a compression spring 21 is fixedly connected between the first push rod 12 and the second push rod 13. The compression spring 21 is connected between the first push rod 12 and the second push rod 13 and inserted into the fixed rod 11. With the cooperation of the cylinder 19 and the connecting plate 20, the two sets of first push rods 12 and second push rods 13 can move synchronously in the corresponding fixed rods 11, so that the roller 15 on the outside of the wheel axle 14 abuts against the bag opening and the rotating frame 10 rotates adaptively, thereby smoothing the bag opening from bottom to top, which is convenient for the subsequent sealing operation of the bag opening into the sealing machine.

[0024] It should be noted that this utility model is a quantitative feeding and filling device. When powder coating is quantitatively bagged, the material is fed into two weighing hoppers 3 by opening the discharge valves at the two output ends of the distributing hopper 2. The weighing hoppers 3 transmit weight signals to the main controller. When the set value is reached, the main controller controls the discharge valve at the bottom of the distributing hopper 2 to close. Subsequently, the packaging bag is manually picked up and the bag opening is placed below the discharge hopper 4 and fixed by the bag opening fixer. Then, the discharge valve at the bottom of one of the weighing hoppers 3 opens, realizing quantitative filling. Material is filled into the packaging bag. After filling, the bag opening retainer opens, allowing the filled packaging bag to fall onto the conveyor 5. Then, the discharge valve at the bottom of the current weighing hopper 3 closes, while the discharge valve at the corresponding discharge port at the bottom of the distribution hopper 2 opens, realizing the replenishment operation of the current weighing hopper 3. Subsequent bagging operations can be performed by opening the discharge valve at the bottom of the other weighing hopper 3. The two weighing hoppers 3 are opened and replenished in sequence, and together with the discharge hopper 4, a quantitative bagging operation is achieved. The bagged bags fall onto the conveyor 5 and move with the conveyor 5. When the bag touches the proximity switch 7 on the baffle 6, the proximity switch 7 sends a signal to the main controller. The main controller controls the conveyor 5 to pause and restarts it after a few seconds via a set delay program. While the conveyor 5 is stopped, the cylinder 19 is activated, pushing the connecting plate 20 and causing the first push rod 12 to move within the fixed rod 11. The first push rod 12 pushes the second push rod 13 via the compression spring 21, causing the multiple rollers 15 on the outer sides of the two axles 14 to abut against each other and clamp the bag opening. As the piston rod of the cylinder 19 continues to push the corresponding first push rod 12 and second push rod 13, thus... The rollers 15 on both sides of the bag opening come into contact with each other and drive the rotating frame 10 to rotate around the rotating shaft 17. This causes the rollers 15 on both sides of the bag opening to smooth the bag opening from bottom to top. Then, the piston rod of the cylinder 19 drives the connecting plate 20 to move back to its original position. This allows the first push rod 12 to work with the compression spring 21 to pull the second push rod 13 back. The second push rod 13 then pulls the wheel shaft 14 back to its original position, causing the rollers 15 to disengage from the bag opening. At this time, the conveyor 5 starts again, thus conveying the bag with the smoothed bag opening towards the sealing mechanism, and conveying the subsequent bagged bags to perform the bag opening smoothing operation.
