Description

Technical Field

[0001] This utility model relates to the field of medicinal material feeding technology, specifically an anti-overflow feeding structure for medicinal material packaging bags. Background Technology

[0002] In the modern pharmaceutical industry, the spill-proof feeding structure of medicinal herb packaging bags is of great significance, especially during the raw material feeding and packaging processes. Traditional medicinal herb packaging bags often experience spillage during feeding, which not only increases production costs but may also affect the quality and safety of the herbs. To solve this problem, spill-proof feeding structures have been designed to improve the efficiency and safety of the packaging process.

[0003] Chinese patent CN216172078U, authorized and published on April 5, 2022, discloses a liquid feeding device, which includes a transfer tank and a weighing device. The weighing device has a weighing platform, and the transfer tank is located on the upper side of the weighing platform. The transfer tank has a liquid inlet and a liquid outlet. The liquid inlet is located at the top of the transfer tank, and a feeding pipe is located on the side of the transfer tank. The feeding pipe is equipped with a first pump or a first valve. One end of the feeding pipe is called the connecting end, which is connected to the liquid outlet, and the other end of the feeding pipe is called the feeding end.

[0004] The aforementioned application document describes adding liquid raw materials into the transfer tank via an inlet. However, when the device feeds the medicinal material into the packaging bag, it often first covers the packaging bag in a container and then rapidly pumps the liquid into the packaging bag. When the liquid rapidly impacts the packaging bag, the packaging bag may become dislodged due to the impact, causing the liquid to spill out. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-overflow feeding structure for medicinal herb packaging bags, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-overflow feeding structure for medicinal herb packaging bags, comprising: A storage bin and a feeding bin, wherein a conveying pipe for transmitting liquid medicine is installed between the storage bin and the feeding bin; An impeller is rotatably connected inside the storage bin. A rotating rod is fixedly connected to the side of the impeller. A hydraulic chamber one is mounted on the outside of the rotating rod. A sliding block is slidably connected inside the hydraulic chamber one via an elastic telescopic rod. An arc-shaped plate is slidably connected to the side of the hydraulic chamber one via a piston. A hydraulic chamber two is mounted on the side of the feeding bin. A force-bearing rod one is slidably connected to one end of the hydraulic chamber two via a piston. An arc-shaped rod one is slidably connected to the other end of the hydraulic chamber two via a piston. A spring one is mounted on the side of the force-bearing rod one. A limit plate is rotatably connected to the side of the feeding bin.

[0006] Preferably, the force-bearing rod is located on the side of the arc-shaped plate and is in contact with the arc-shaped plate.

[0007] Preferably, the limiting plate is located on the side of the arc-shaped rod and is fixed to the arc-shaped rod.

[0008] Preferably, the storage bin and the feeding bin are equipped with auxiliary anti-overflow components on their sides.

[0010] Preferably, the force-bearing plate is located on the side of the second arc-shaped rod and is fixed to the second arc-shaped rod.

[0011] This utility model provides an anti-overflow feeding structure for medicinal material packaging bags. It has the following beneficial effects: (1) The packaging bag of the medicinal material uses an anti-overflow feeding structure to cover the packaging bag in the feeding hopper. When the liquid pump is activated, the liquid medicine in the storage hopper is drawn into the packaging bag in the feeding hopper through the conveying pipe. With the help of the impeller, rotating rod, hydraulic chamber one, elastic telescopic rod, sliding block, arc plate, hydraulic chamber two, force rod one, arc rod one, spring one and limit plate, the packaging bag covering the surface of the feeding hopper can be pressed tightly to prevent the packaging bag from dislodging under the rapid impact of the liquid medicine, thereby preventing the liquid medicine from overflowing.

[0012] (2) The packaging bag of the medicinal material uses an anti-overflow feeding structure. As the medicine liquid in the packaging bag gradually fills up, the packaging bag can squeeze the squeezing plate. With the help of spring two, hydraulic chamber three, sensing block, arc rod two, spring three, force plate and block, the conveying pipe that was originally in a connected state can be converted into a closed state, further preventing the medicine liquid in the packaging bag from overflowing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, please refer to Figures 1-4 An anti-overflow feeding structure for medicinal material packaging bags, comprising: The storage bin 100 and the feeding bin 200 are connected by a conveying pipe 300 for conveying the liquid medicine. An impeller 401 is rotatably connected inside the storage chamber 100, and a rotating rod 402 is fixedly connected to the side of the impeller 401. When a packaging bag is placed inside the feeding chamber 200, the liquid pump connected to the delivery pipe 300 is activated to draw the liquid medicine in the storage chamber 100 into the packaging bag in the feeding chamber 200 through the delivery pipe 300. At this time, the rapidly flowing liquid medicine drives the impeller 401, which is rotatably connected to the storage chamber 100, and the impeller 401 then drives the rotating rod 402, which is fixedly connected to it, to rotate rapidly.

[0017] A hydraulic chamber 403 is mounted on the outer side of the rotating rod 402. Inside the hydraulic chamber 403, a sliding block 405 is slidably connected via an elastic telescopic rod 404. An arc-shaped plate 406 is slidably connected to the side of the hydraulic chamber 403 via a piston. When the rotating rod 402 rotates rapidly, it causes the hydraulic chamber 403, which is fixedly connected to it, to rotate rapidly. Under centrifugal force, the sliding block 405 inside the hydraulic chamber 403 stretches the elastic telescopic rod 404 and slides along the inner wall of the hydraulic chamber 403, thereby squeezing the oil originally stored in the hydraulic chamber 403. The oil in the hydraulic chamber 403 then flows towards the side closer to the arc-shaped plate 406, causing the arc-shaped plate 406, which is slidably connected to the hydraulic chamber 403 via a piston, to extend out of the hydraulic chamber 403.

[0018] The side of the feeding hopper 200 is equipped with a hydraulic hopper 2 407. One end of the hydraulic hopper 2 407 is slidably connected to a force rod 408 via a piston. The force rod 408 is located on the side of the arc plate 406 and is in contact with the arc plate 406. The other end of the hydraulic hopper 2 407 is slidably connected to an arc rod 409 via a piston. A spring 410 is installed on the side of the force rod 408. A limit plate 411 is rotatably connected to the side of the feeding hopper 200. The limit plate 411 is located on the side of the arc rod 409 and is fixed to the arc rod 409. As the arc plate 406 extends synchronously with the rotation of the hydraulic chamber 403, it can squeeze the force rod 408 and drive it to move to the side. In conjunction with the hydraulic chamber 407 which is slidably connected to the force rod 408 via a piston, the arc rod 409 which is slidably connected to the hydraulic chamber 407 via a piston extends out of the hydraulic chamber 407. The arc rod 409 then drives the limiting plate 411 which is fixedly connected to it to rotate, pressing the packaging bag covering the surface of the feeding hopper 200 to prevent the packaging bag from dislodging under the rapid impact of the liquid medicine, thereby preventing the liquid medicine from spilling out.

[0019] In use, the packaging bag is placed inside the feeding hopper 200. The liquid pump connected to the conveying pipe 300 is activated to draw the liquid medicine from the storage hopper 100 into the packaging bag in the feeding hopper 200 through the conveying pipe 300. At this time, the rapidly flowing liquid medicine drives the impeller 401, which is rotatably connected to the storage hopper 100. The impeller 401 then drives the rotating rod 402, which is fixedly connected to it, to rotate rapidly. This causes the rotating rod 402 to drive the hydraulic chamber 403, which is fixedly connected to it, to rotate rapidly. Under the action of centrifugal force, the sliding block 405 inside the hydraulic chamber 403 stretches the elastic telescopic rod 404 and slides along the inner wall of the hydraulic chamber 403, thereby squeezing the oil originally stored in the hydraulic chamber 403. The oil then flows towards the side closer to the arc plate 406, causing the arc plate 406, which is slidably connected to the hydraulic chamber 403 via a piston, to extend out of the hydraulic chamber 403. The arc plate 406 extends synchronously as the hydraulic chamber 403 rotates, thus squeezing the force rod 408 and causing it to move to the side. In conjunction with the hydraulic chamber 407, which is slidably connected to the force rod 408 via a piston, the arc rod 409, which is slidably connected to the hydraulic chamber 407 via a piston, extends out of the hydraulic chamber 407. The arc rod 409 then causes the limiting plate 411, which is fixedly connected to it, to rotate, thus compressing the packaging bag covering the surface of the feeding hopper 200.

[0020] Example 2, please refer to Figures 1-6 Based on Embodiment 1, auxiliary anti-overflow components 500 are installed on the sides of the storage bin 100 and the feeding bin 200. The auxiliary anti-overflow components 500 include a hydraulic chamber 3 503 installed on the side of the feeding bin 200. The inside of the feeding bin 200 is connected to a squeezing plate 502 via a spring 2 501. One end of the hydraulic chamber 3 503 is slidably connected to a sensing block 504 via a piston. As the medicine in the packaging bag gradually fills up, the packaging bag can squeeze the squeezing plate 502, and the squeezing plate 502 compresses the spring 2 501 and moves downward. When the medicine in the packaging bag is full, the side of the squeezing plate 502 can squeeze the sensing block 504 and drive the sensing block 504 to move to the side. In conjunction with the hydraulic chamber 3 503 which is slidably connected to the sensing block 504 via a piston, the sensing block 504 squeezes the oil originally stored in the hydraulic chamber 3 503 during the movement.

[0021] The other end of the hydraulic chamber 3 503 is slidably connected to the arc rod 2 505 via a piston. The side of the sensing block 504 is equipped with a spring 3 506. The end of the spring 3 506 away from the sensing block 504 is mounted on the inner wall of the hydraulic chamber 3 503. The side of the conveying pipe 300 is rotatably connected to a force plate 507. The force plate 507 is located on the side of the arc rod 2 505 and is fixed to the arc rod 2 505. A block 508 is fixedly connected to the side of the force plate 507. When the oil originally stored in the hydraulic chamber 3 503 is squeezed, the oil flows towards the side closer to the arc-shaped rod 2 505, causing the arc-shaped rod 2 505, which is connected to the hydraulic chamber 3 503 by a piston sliding connection, to move out of the hydraulic chamber 3 503. The arc-shaped rod 2 505 then drives the force plate 507 fixedly connected to it to rotate, causing the force plate 507 to drive the block 508 fixedly connected to it to rotate, changing the originally connected delivery pipe 300 into a closed state, further preventing the medicine liquid in the packaging bag from overflowing.

[0022] In use, based on Example 1, as the medicine in the packaging bag gradually fills, the packaging bag can squeeze the squeezing plate 502, and the squeezing plate 502 compresses the second spring 501 and moves downward. When the medicine in the packaging bag is full, the side of the squeezing plate 502 can squeeze the sensing block 504 and drive the sensing block 504 to move to the side. In conjunction with the hydraulic chamber 3 503 which is slidably connected to the sensing block 504 by a piston, the sensing block 504 squeezes the oil originally stored in the hydraulic chamber 3 503 during the movement. The oil then flows to the side closer to the arc-shaped rod 2 505, causing the arc-shaped rod 2 505 which is slidably connected to the hydraulic chamber 3 503 to move out of the hydraulic chamber 3 503. The arc-shaped rod 2 505 then drives the force plate 507 which is fixedly connected to it to rotate, so that the force plate 507 drives the block 508 which is fixedly connected to it to rotate, changing the delivery pipe 300 which was originally in a connected state to a closed state.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
