Automatic material supplementing assembly of powder production line batching bin

Abstract

This utility model discloses an automatic feeding component for a powder production line's batching silo, comprising a frame, a batching silo within the frame, a storage silo fixedly mounted on the top of the frame, a discharge port at the bottom of the storage silo, a weighing device fixedly mounted on the top of the batching silo, and a housing fixedly mounted on the weighing device. This utility model, through the design of baffles, a weighing box, and a buffer assembly, allows powder from the storage silo to fall into the weighing box through the discharge port during use. As the weighing box is subjected to the weight of the powder, it moves slowly downwards via the buffer assembly. This movement of the weighing box causes two baffles to move slowly towards each other via a transmission assembly, thereby blocking a portion of the bottom area of ​​the discharge port. This slows the descent of the powder from the storage silo and allows the baffle assembly to promptly block the discharge port when the powder weight in the weighing box is about to reach the target level, thus improving batching accuracy and processing quality.

Description

Technical Field

[0001] This utility model relates to the field of powder batching and replenishment technology, and more specifically, to an automatic replenishment component for the batching silo of a powder production line. Background Technology

[0002] In the processing of some powders, such as calcium carbonate powder, it is often necessary to add other powder additives to meet different processing requirements. During the batching process, workers need to use automatic feeding components to easily add different powder additives to the batching hopper in different amounts for mixing, thereby improving work efficiency.

[0003] However, existing technologies have some problems: When using existing automatic feeding components, the powder in the storage silo falls into the weighing box for weighing and batching. However, in actual use, after the discharge port of the storage silo is opened, the falling speed of the powder does not slow down as the amount of powder in the weighing box increases. Therefore, when the weight of the powder in the weighing box is about to reach the target, it is difficult to stop the powder from falling in time when the staff covers the discharge port of the storage silo. This can easily cause the powder to be overweight, which in turn affects the accuracy of batching and reduces the processing quality. Therefore, we propose an automatic feeding component for the batching silo of the powder production line. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for an automatic feeding component for the batching silo in a powder production line.

[0005] According to a first aspect of this utility model, an automatic feeding component for a powder production line's batching silo is provided, comprising a frame, a batching silo within the frame, a storage silo fixedly mounted on the top of the frame, a discharge port at the bottom of the storage silo, a weighing device fixedly mounted on the top of the batching silo, a housing fixedly mounted on the weighing device, the bottom of the storage silo extending into the housing, a baffle assembly on the storage silo for controlling the downward sliding of powder in the storage silo, a weighing box connected to the inside of the housing via a buffer assembly, baffles movably inserted into both sides of the top of the inner wall of the housing, the baffles being connected to the weighing box via a transmission assembly, the weighing box being able to control the distance between the two baffles via the transmission assembly, a discharge pipe fixedly mounted on the bottom of the weighing box, the bottom end of the discharge pipe extending into the batching silo, a discharging assembly on the discharge pipe for controlling the downward sliding of powder in the weighing box into the batching silo.

[0006] Optionally, the material blocking assembly includes a first stop block, which is movably inserted into the storage bin, and a first electric push rod is fixedly installed on the outer shell, with the telescopic end of the first electric push rod fixedly connected to the first stop block.

[0007] Optionally, the transmission assembly includes a plate frame, which is fixedly connected to a baffle plate. Both sides of the plate frame have through holes, and a round block located inside the through hole is fixedly installed on the weighing box.

[0008] Optionally, the diameter of the circular block is adapted to the width of the through hole, and the inner wall of the through hole is coated with a lubricating layer.

[0009] Optionally, the feeding assembly includes two second stops, which are movably inserted into both sides of the feeding tube. A second electric push rod is fixedly installed on both sides of the bottom of the weighing box, and the telescopic end of the second electric push rod is fixedly connected to the second stop.

[0010] Optionally, a pad is fixedly installed at the opposite ends of the two second blocks, and the thickness of the pad is the same as the thickness of the second block.

[0011] Optionally, the buffer assembly includes a telescopic rod, which is fixedly installed on the bottom of the inner wall of the housing. The other end of the telescopic rod is fixedly connected to the weighing box.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] like Figures 1-5As shown, the automatic feeding component of the powder production line batching silo includes a frame 1, a batching silo is located inside the frame 1, a storage silo 2 is fixedly installed on the top of the frame 1, a discharge port 3 is opened at the bottom of the storage silo 2, a weighing device 4 is fixedly installed on the top of the batching silo, a shell 5 is fixedly installed on the weighing device 4, the bottom of the storage silo 2 extends into the shell 5, a baffle assembly is provided on the storage silo 2 to control the powder in the storage silo 2 to slide downwards, a weighing box 6 is connected to the inside of the shell 5 through a buffer assembly, baffles 7 are movably inserted into both sides of the top of the inner wall of the shell 5, the baffles 7 are connected to the weighing box 6 through a transmission assembly, the weighing box 6 can control the distance between the two baffles 7 through the transmission assembly, a discharge pipe 8 is fixedly installed at the bottom of the weighing box 6, the bottom end of the discharge pipe 8 extends into the batching silo, a discharge assembly is provided on the discharge pipe 8 to control the powder in the weighing box 6 to slide downwards into the batching silo.

[0029] When the powder falling into the weighing box 6 moves downward under gravity, the transmission component enables the two baffles 7 to move towards each other, thereby blocking the area below the discharge port 3. This slows down the amount of powder falling from the storage bin 2 when the weight of the powder in the weighing box 6 is about to reach the target, making it easier to accurately control the amount of powder in the weighing box 6 in the future.

[0030] The automatic feeding component of the powder production line batching bin includes a first stop block 9, which is movably inserted into the storage bin 2. A first electric push rod 10 is fixedly installed on the outer shell 5, and the telescopic end of the first electric push rod 10 is fixedly connected to the first stop block 9.

[0031] By activating the first electric actuator 10 to pull the first stop 9, the first stop 9 can be released from blocking the discharge port 3, allowing the powder stored in the storage bin 2 to fall from the discharge port 3 into the weighing box 6 for weighing and batching. After batching is completed, activating the first electric actuator 10 will block the first stop 9 from blocking the discharge port 3, thus preventing the powder from falling further.

[0032] The automatic feeding component of the powder production line batching bin includes a transmission component including a plate frame 11, which is fixedly connected to the baffle 7. Both sides of the plate frame 11 are provided with through holes 12, and a round block 13 located inside the through hole 12 is fixedly installed on the weighing box 6.

[0033] When the powder falling into the weighing box 6 moves downward under gravity, it can drive the round block 13 to move downward. This causes the outer surface of the round block 13 to press against the inner wall of the through hole 12, which in turn causes the two plate frames 11 to drive the two baffles 7 to move towards each other. This allows the baffles 7 to block a part of the area below the discharge port 3, thereby slowing down the amount of powder falling from the storage bin 2 when the weight of the powder in the weighing box 6 is about to reach the target. This makes it easier to control the weight of the powder in the weighing box 6 more accurately and improves the accuracy of the batching.

[0034] In the above-mentioned powder production line automatic feeding component for the batching bin, the diameter of the round block 13 is matched with the width of the through hole 12, and the inner wall of the through hole 12 is coated with a lubricating layer.

[0035] By coating the inner wall of the through hole 12 with a lubricating layer, the circular block 13 can slide more smoothly inside the through hole 12.

[0036] The automatic feeding component of the powder production line batching silo includes two second blocks 15, which are movably inserted into both sides of the feeding pipe 8. The bottom sides of the weighing box 6 are fixedly installed with second electric push rods 14, and the telescopic ends of the second electric push rods 14 are fixedly connected to the second blocks 15.

[0037] Once the weight of the powder in the weighing box 6 reaches the target, the operator can activate the second electric actuator 14 to make the two second stops 15 move in opposite directions, thereby releasing the sealing effect on the discharge pipe 8, allowing the powder in the weighing box 6 to slide down through the discharge pipe 8 into the mixing hopper.

[0038] In the above-mentioned automatic feeding component of the powder production line batching bin, a pad 16 is fixedly installed at the opposite ends of the two second blocks 15, and the thickness of the pad 16 is the same as the thickness of the second blocks 15.

[0039] The pad 16 can be made of rubber. Due to the soft and elastic nature of rubber, the two second blocks 15 can fit more tightly through the two pads 16, thereby improving the sealing effect.

[0040] The automatic feeding component of the powder production line batching bin includes a buffer component including a telescopic rod 17. The telescopic rod 17 is fixedly installed on the bottom of the inner wall of the outer shell 5. The other end of the telescopic rod 17 is fixedly connected to the weighing box 6. A spring 18 is movably sleeved on the outer surface of the telescopic rod 17. The two ends of the spring 18 are respectively fixedly connected to the outer shell 5 and the weighing box 6.

[0041] When powder falls into the weighing box 6, the weight of the powder will compress the spring 18 and the telescopic rod 17, causing the weighing box 6 to move slowly downwards. This allows the two baffles 7 to move slowly towards each other, preventing the two baffles 7 from moving rapidly towards each other and blocking the discharge port 3, thus affecting the powder falling rate.

[0042] The automatic feeding component of the powder production line batching silo has four telescopic rods 17, which are evenly distributed on the bottom of the inner wall of the outer shell 5.

[0043] The automatic feeding component of the powder production line batching silo has a loose material block 19 fixedly installed at the bottom of the feeding pipe 8. The loose material block 19 has a conical appearance.

[0044] By designing the bulk material block 19, when the powder in the weighing box 6 falls onto the bulk material block 19 through the feeding pipe 8, it will slide along the outer surface of the bulk material block 19, thus becoming more dispersed when it falls into the mixing hopper, which is beneficial for subsequent mixing.

[0045] The automatic feeding component of the powder production line's batching silo has a square-shaped weighing box 6 with an inclined bottom inner wall.

[0046] The inclined design of the bottom of the inner wall of the weighing box 6 makes it easier for the weighed powder to slide down and avoid residue, thus ensuring the accuracy of the dispensing.

[0047] Working principle and usage process of this utility model:

[0048] When replenishing powder, if a large amount of powder needs to be added, the operator first activates the first electric actuator 10 to pull the first stop 9, removing the obstruction of the discharge port 3. This allows the powder in the storage bin 2 to fall into the weighing box 6 through the discharge port 3. As the amount of powder in the weighing box 6 increases, the weighing box 6 moves downward under the force of the powder's gravity. Under the action of the telescopic rod 17 and the spring 18, it slowly drives the round block 13 downward, causing the outer surface of the round block 13 to press against the inner wall of the through hole 12. This causes the two plate frames 11 to move the two baffles 7 towards each other, thus allowing the baffles 7 to block the area below the discharge port 3, thereby enabling... When the powder in weighing box 6 is about to reach the target weight, the falling amount of powder in storage bin 2 is slowed down. When the weighing device 4 detects that the powder in weighing box 6 has reached the target weight, the operator controls the first electric push rod 10 to make the first stop block 9 block the discharge port 3, which can stop the powder from falling further in time, and more accurately control the weight of the powder in weighing box 6, thus improving the accuracy of batching. Then, the second electric push rod 14 is activated to make the two second stops 15 move in opposite directions, which allows the powder in weighing box 6 to fall into the batching bin through the discharge pipe 8. As the powder in weighing box 6 decreases, weighing box 6 will also slowly move upward under the elastic force of spring 18, so that the baffle 7 returns to its original position.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
