Description

Technical Field

[0001] The utility model relates to the technical field of flow scales, and specifically relates to a discharging device for a flow scale. Background Art

[0002] A discharging device for a flow scale generally refers to a device for weighing and discharging materials. It automatically completes the discharging and weighing operations according to pre-set parameters, and stops discharging after meeting the set requirements. The discharging device of the packing scale can improve production efficiency and ensure product quality.

[0003] The existing discharging device for a flow scale generally consists of a weighing system, a sensor and a discharging system. Usually, a weighing device is arranged at the lower end of the discharging bin. When a certain weight is reached, the weighing sensor starts the motor to drive the screw to push the blade door to close the storage bin.

[0004] However, in the existing discharging device for a flow scale, the weighing sensor usually starts the motor to horizontally close the blade door, and the discharging bin closes slowly. Therefore, there may be a certain error in discharging. At the same time, the existing discharging device for a flow scale cannot adjust the discharging speed according to the required discharging weight. Therefore, a discharging device for a flow scale is proposed for the above problems. Content of the Utility Model

Start the second motor to drive the screw rod to rotate, so that the slider and the connecting rod move to one side, the connecting rod pushes the ring plate to rotate, thereby adjusting the length of the connecting plate inside the ring plate, and further separating the three sector plates from each other for discharging. When the discharging reaches the predetermined weight, the weighing sensor starts the second motor to reverse, driving the three sector plates to approach each other, increasing the closing speed of the discharging port at the lower end of the feeding bin, reducing the discharging error. At the same time, the distance that the slider slides on the screw rod is limited by the bolt, which is convenient for adjusting the distance that the three sector plates are separated to adjust the discharging speed.

[0007] Preferably, a first motor is fixed at the center of the top of the feeding bin, and a spiral conveyor is fixed at the output end of the first motor. It is convenient to adjust the discharging speed of the stored materials in the feeding bin through the spiral conveyor.

[0008] Preferably, a square groove is opened on one side plate of the sector plate, and a square block is fixed on the other side plate of the sector plate. Through the square groove and the square block, the three sector plates are more stable when combined, increasing the stability and sealing performance of the discharging port at the lower end of the feeding bin.

[0009] Preferably, the three sector plates combine to form a circle and are larger than the bottom diameter of the discharging port, so that the sector plates can close the discharging port of the feeding bin. Setting three sector plates is convenient for increasing the closing speed of the discharging port.

[0010] Preferably, connecting columns are fixed at the upper and lower ends in the middle of the three arc grooves, and sleeve plates are rotatably arranged between every two of the six connecting columns. The connecting plates are all slidably arranged in the sleeve plates. Through the connecting columns, on the one hand, it plays a supporting role, and on the other hand, it enables the sleeve plates to rotate in the arc grooves, and the connecting plates slide in the sleeve plates, and the sleeve plates limit the sliding of the connecting plates.

[0011] Preferably, the feeding bin has a funnel-shaped structure, which is convenient for discharging the stored materials in the feeding bin.

[0012] The beneficial effects of the present utility model are as follows: By starting the second motor, the screw rod is driven to rotate, so that the slider and the connecting rod move to one side, and the connecting rod pushes the ring plate to rotate, thereby adjusting the length of the connecting plate inside the ring plate, and further separating the three sector plates from each other for discharging. When the discharging reaches the predetermined weight, the weighing sensor starts the second motor to reverse, driving the three sector plates to approach each other, increasing the closing speed of the discharging port at the lower end of the feeding bin, reducing the discharging error. At the same time, the distance that the slider slides on the screw rod is limited by bolts, which is convenient for adjusting the distance that the three sector plates move away from each other to adjust the discharging speed, avoiding excessive flow of materials into bags with too small weight, resulting in spillage of stored materials.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 As shown, a discharging device for a flow scale includes a fixed table 1. At the center of the top of the fixed table 1, a feeding bin 2 is fixed. Around the center of the bottom of the fixed table 1, four support rods 4 are fixed. At the bottom of the four support rods 4, a bottom plate 5 is fixed. At the center of the top of the bottom plate 5, a weighing device 6 is fixed. In the middle of the front end face of the weighing device 6, a weighing sensor 7 is fixed. On one side of the bottom of the fixed table 1, a second motor 12 is fixed. The output end of the second motor 12 is fixed with a screw rod 15. Near the second motor 12 at the bottom of the fixed table 1, a fixed block 13 is fixed. The screw rod 15 penetrates through the fixed block 13 threadedly on the side close to the second motor 12. At the front end of the screw rod 15 at the bottom of the fixed table 1, a sliding groove 14 is formed. A sliding block 22 is slidably arranged in the sliding groove 14. A bolt 24 is threadedly sleeved on one end of the screw rod 15 away from the second motor 12. The other side of the screw rod 15 penetrates through the sliding block 22 threadedly. At the bottom of the sliding block 22, a connecting rod 23 is hinged. On one side of the connecting rod 23, an annular plate 9 is fixed. Three arc grooves 10 are evenly formed on the axial body of the annular plate 9. Around the center of the bottom of the fixed table 1, three fixed columns 16 are fixed. At the bottom of the three fixed columns 16, connecting plates 17 are all fixed. At one end of the three connecting plates 17, sector plates 11 are all fixed.

[0023] When discharging, start the second motor 12 to drive the screw rod 15 to rotate, so that the sliding block 22 and the connecting rod 23 move to one side. The connecting rod 23 pushes the annular plate 9 to rotate. When the annular plate 9 rotates, the connecting plate 17 slides in the sleeve plate 18, so that the length of the connecting plate 17 inside the annular plate 9 is reduced when the connecting plate 17 slides, and then the three sector plates 11 move away from each other for discharging. At the same time, the first motor 3 drives the spiral conveyor wheel 8 to increase the discharging speed of the feeding bin 2. When the material is discharged to the predetermined weight, the weighing sensor 7 starts the second motor 12 to reverse. The model of the weighing sensor 7 is YZC-522. The reverse rotation of the second motor 12 drives the annular plate 9 to rotate in the reverse direction, so that the connecting plate 17 slides to increase the length inside the annular plate 9, and the three sector plates 11 move closer to each other to close. The sizes of the square block 21 and the square groove 20 are the same, so that the three sector plates 11 can be accurately closed. Between the three sector plates 11, through the square block 21 and the square groove 20, the stability of the sector plates 11 is increased. Through the equal-ratio closing and shrinking of the three sector plates 11, the closing speed of the discharging port at the lower end of the feeding bin 2 is increased, and the discharging error is reduced. By the bolt 24, the sliding distance of the sliding block 22 on the screw rod 15 is limited, which is convenient for adjusting the distance between the three sector plates 11 away from each other to adjust the discharging speed.

[0024] A first motor 3 is fixed at the center of the top of the feeding bin 2. A spiral conveyor wheel 8 is fixed at the output end of the first motor 3. The rotation speed of the spiral conveyor wheel 8 is adjusted by the rotation speed of the first motor 3, which is convenient for adjusting the discharging speed and flow rate of the stored material in the feeding bin 2. A square groove 20 is formed on one side plate of the sector plate 11, and a square block 21 is fixed on the other side plate of the sector plate 11. Through the square groove 20 and the square block 21, the three sector plates 11 can be firmly closed. This not only increases the stability of the support for the stored material at the discharging port at the lower end of the feeding bin 2, but also increases the sealing property of the discharging port. The three sector plates 11 together form a circle, and the diameter of the circle is larger than the bottom diameter of the discharging port. The circle enables the sector plates 11 to completely seal the discharging port at the lower end of the feeding bin 2. At the same time, by synchronously contracting and moving away the three sector plates 11, the speed of closing and opening the discharging port is increased, and the discharging error is reduced. Connecting columns 19 are fixed at both the upper and lower ends in the middle of the six arc grooves 10. A sleeve plate 18 is rotatably arranged between every two of the six connecting columns 19. The connecting plates 17 are all slidably arranged in the sleeve plate 18. Through the connecting columns 19, on the one hand, it plays a supporting role, and on the other hand, it enables the sleeve plate 18 to rotate in the arc groove 10, and the connecting plate 17 slides in the sleeve plate 18, and the sleeve plate 18 limits the sliding of the connecting plate 17. The feeding bin 2 has a funnel-shaped structure, and the funnel-shaped structure is convenient for discharging the stored material in the feeding bin 2.

[0025] Working principle: When discharging, the second motor 12 is started to drive the screw rod 15 to rotate, so that the slider 22 and the connecting rod 23 move to one side. The connecting rod 23 pushes the ring plate 9 to rotate. When the ring plate 9 rotates, the connecting plate 17 slides in the sleeve plate 18, so that the length of the connecting plate 17 inside the ring plate 9 is reduced when the connecting plate 17 slides, and then the three sector plates 11 move away from each other for discharging. At the same time, the first motor 3 drives the spiral conveyor wheel 8 to increase the discharging speed of the feeding bin 2. When the material is discharged to the predetermined weight, the weighing sensor 7 starts the second motor 12 to reverse. The model of the weighing sensor 7 is YZC-522. The reverse rotation of the second motor 12 drives the ring plate 9 to rotate in the reverse direction, so that the connecting plate 17 slides to increase the length inside the ring plate 9, and the three sector plates 11 move closer to each other and close. The sizes of the square block 21 and the square groove 20 are the same, so that the three sector plates 11 can be accurately closed. Through the square block 21 and the square groove 20 between the three sector plates 11, the stability of the sector plates 11 is increased. Through the equal-ratio closing and shrinking of the three sector plates 11, the closing speed of the discharging port at the lower end of the feeding bin 2 is increased, and the discharging error is reduced. The distance that the slider 22 slides on the screw rod 15 is limited by the bolt 24, which is convenient for adjusting the distance that the three sector plates 11 move away to adjust the discharging speed.
