Abstract
Description
Technical Field
[0001] This utility model relates to the field of pill production equipment technology, and in particular to a pressure balancing cup for pill production. Background Technology
[0002] Currently, in the production of pills, for drop pills, the pills are made using the drop method. Specifically, solid or liquid drugs are dissolved, emulsified, or suspended in a suitable molten matrix, and then dripped into another immiscible coolant through a suitable dropper. Due to surface tension, the droplets form spherical shapes and then cool and solidify to form pills.
[0003] During the daily operation of the dripping pellet product, as the liquid raw material level decreases, the pressure at the dripping point changes, resulting in changes in the product volume. Currently, the method used is to manually adjust the dripping flow rate to offset the impact of pressure changes. However, manual operation is subject to some errors and is relatively inconvenient, leading to increased production costs. Utility Model Content
[0004] The purpose of this invention is to solve the problem that when the liquid level of the raw material decreases during the production of drop pills, the pressure at the dripping point changes, causing changes in the product filling amount. This leads to some errors in manual operation, which is inconvenient and increases production costs. Therefore, this invention proposes a pressure balancing cup for pill production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure balancing cup for pill production, comprising a cup base, wherein a plurality of mounting holes are provided on the outer surface of the cup base, a cup body is fixedly connected to one side of the cup base, an inlet pipe is fixedly connected to the top of the cup body, an outlet pipe is fixedly connected to the bottom of the cup body, the outlet pipe is a curved pipe, a balancing device is provided on the outer surface of the inlet pipe, the balancing device comprises a round rod, a through hole is provided inside the inlet pipe, an L-shaped hole is provided on one side of the inner wall of the through hole, the outer surface of the round rod is slidably connected to the inner wall of the through hole, and a float plate is fixedly connected to the bottom of the round rod.
[0006] The effect achieved by the above components is as follows: By setting up a float plate, when using the balance cup, the cup body is installed below the discharge port of the material box through the mounting holes on the outer surface of the cup seat. The inlet pipe is connected to the discharge port. The liquid inside the material box enters the through hole in the inlet pipe and enters the interior of the cup body through the L-shaped hole. Then it is output through the outlet pipe at the bottom of the cup body. Since the outlet pipe is curved, the output rate of the liquid inside the cup body through the outlet pipe is less than the input rate at the inlet pipe. The liquid inside the material box continues to enter the interior of the cup body, causing the liquid level inside the cup body to rise. The float plate pushes the round rod to slide upward on the inner wall of the through hole, so that the round rod gradually closes the end of the L-shaped hole located inside the through hole. When the liquid level inside the cup body drops, the round rod will move downward and gradually open the end of the L-shaped hole, allowing the liquid inside the material box to enter the interior of the cup body through the L-shaped hole. This keeps the liquid level inside the cup body at a certain height as much as possible and avoids changes in the product filling volume.
[0007] Preferably, one side of the top end of the round rod is a bevel, and the angle of the beveled side of the top end of the round rod is parallel to the angle of the L-shaped hole near the through hole.
[0008] The effect achieved by the above components is that by setting one side of the top of the round rod to be inclined, the liquid can more easily slide from the top of the round rod into the L-shaped hole when it enters the inlet pipe and reaches the top of the round rod.
[0009] Preferably, an L-shaped rod is fixedly connected to one side of the round rod, and a rectangular groove is formed on one side of the inner wall of the liquid inlet pipe, with one end of the L-shaped rod sliding on the inner wall of the rectangular groove.
[0010] The effect achieved by the above components is that when the round rod moves up and down, one end of the L-shaped rod will slide on the inner wall of the rectangular groove, which limits the angle between the round rod and the liquid inlet pipe and avoids the angle of the round rod from deflecting as much as possible.
[0011] Preferably, a round block is fixedly connected to one end of the L-shaped rod, a pressure sensor is provided on one side of the inner wall of the liquid inlet pipe, and a warning light is provided on one side of the top of the cup body.
[0012] The effect achieved by the above components is as follows: when the liquid level inside the cup rises and the round rod closes one end of the L-shaped hole, the round rod will drive the L-shaped rod to move upward, so that one side of the round block contacts one side of the pressure sensor and causes the pressure parameter of the pressure sensor to change. The control system inside the cup will turn on the warning light to remind the staff that the balancing device is operating.
[0013] Preferably, positioning grooves are provided on both sides of the round rod, and positioning blocks are fixedly connected to both sides of the bottom end of the inner wall of the liquid inlet pipe, with the positioning blocks located inside the positioning grooves.
[0014] The effect achieved by the above components is that when the round rod moves up and down, the positioning grooves on both sides will slide on the outer surface of the positioning block. The positioning block and positioning groove can further limit the angle between the float and the cup body, and avoid the float from tilting inside the cup body as much as possible.
[0015] Preferably, the outer surface of the inlet pipe is provided with a sealing device, the sealing device includes a sealing cylinder, the bottom end of the sealing cylinder is fixedly connected with a threaded ring, the outer surface of the inlet pipe is provided with a threaded groove, and the inner wall of the threaded ring is threadedly connected to the outer surface of the inlet pipe where the threaded groove is provided.
[0016] The effect achieved by the above components is as follows: when connecting the inlet pipe to the outlet pipe of the material box, the threaded ring can be first put on the outer surface of the inlet pipe, and the sealing cylinder can be pushed to rotate to connect the threaded ring to the outer surface of the inlet pipe with the threaded groove. The sealing cylinder is then installed on the outside of the inlet pipe, and the connection between the inlet pipe and the outlet pipe of the material box is further sealed by the sealing cylinder, so as to avoid the liquid inside the material box from leaking out when passing through the connection between the outlet pipe and the inlet pipe.
[0017] Preferably, an annular strip is fixedly connected to the top of the inner wall of the sealing cylinder, and the annular strip is made of rubber.
[0018] The effect achieved by the above components is that by setting a rubber ring strip, the outside of the connection between the liquid inlet pipe and the discharge pipe of the material box can be further sealed, thereby improving the sealing effect of the sealing device.
[0019] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded ring, and the protrusions are circumferentially distributed on the outer surface of the threaded ring.
[0020] The effect achieved by the above components is that the protrusions on the outer surface of the threaded ring make it easier to rotate the threaded ring and disassemble the sealing cylinder.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a balancing device, the liquid inside the cup will continue to rise as the liquid in the tank continues to enter the cup, causing the round rod to close the L-shaped hole. After the liquid level drops, one end of the L-shaped hole will be opened, so as to keep the liquid level inside the cup at a certain height as much as possible and avoid changes in the product filling amount.

[0030] Example 1, as Figure 1-4 As shown, a pressure balancing cup for pill production includes a cup base 1. The outer surface of the cup base 1 has several mounting holes 4. A cup body 5 is fixedly connected to one side of the cup base 1. An inlet pipe 6 is fixedly connected to the top of the cup body 5, and an outlet pipe 7 is fixedly connected to the bottom of the cup body 5. The outlet pipe 7 is a curved pipe. A balancing device 2 is provided on the outer surface of the inlet pipe 6. The balancing device 2 includes a round rod 23. A through hole 21 is provided inside the inlet pipe 6. An L-shaped hole 22 is provided on one side of the inner wall of the through hole 21. The outer surface of the round rod 23 is slidably connected to the inner wall of the through hole 21. A float plate 24 is fixedly connected to the bottom of the round rod 23. By setting the float plate 24, when using the balancing cup, the cup body 5 is installed below the outlet of the material box through the mounting holes 4 on the outer surface of the cup base 1, and the inlet pipe 6 is connected to the outlet. The liquid inside the material box... The liquid entering the inlet pipe 6 through the through hole 21 will pass through the L-shaped hole 22 into the interior of the cup body 5, and then be output through the outlet pipe 7 at the bottom of the cup body 5. Since the outlet pipe 7 is curved, the output rate of the liquid inside the cup body 5 through the outlet pipe 7 is less than the input rate at the inlet pipe 6. As the liquid in the tank continues to enter the interior of the cup body 5, the liquid level inside the cup body 5 will rise. The float plate 24 pushes the round rod 23 to slide upward on the inner wall of the through hole 21, so that the round rod 23 gradually closes the end of the L-shaped hole 22 located inside the through hole 21. When the liquid level inside the cup body 5 drops, the round rod 23 will move downward and gradually open the end of the L-shaped hole 22, so that the liquid inside the tank can enter the interior of the cup body 5 through the L-shaped hole 22, so as to keep the liquid level inside the cup body 5 at a certain height as much as possible and avoid changes in the product filling volume.
[0031] Reference Figure 2-4 As shown in this embodiment: one side of the top of the round rod 23 is inclined, and the angle of the inclined side of the top of the round rod 23 is parallel to the angle of the end of the L-shaped hole 22 near the through hole 21. By setting one side of the top of the round rod 23 to be inclined, when the liquid enters the inlet pipe 6 and reaches the top of the round rod 23, it is easier to slide from the top of the round rod 23 into the L-shaped hole 22. An L-shaped rod 25 is fixedly connected to one side of the round rod 23. A rectangular groove 27 is opened on one side of the inner wall of the inlet pipe 6. One end of the L-shaped rod 25 slides on the inner wall of the rectangular groove 27. When the round rod 23 moves up and down, one end of the L-shaped rod 25 will slide on the inner wall of the rectangular groove 27, which limits the angle between the round rod 23 and the inlet pipe 6 and avoids the angle of the round rod 23 from deflecting as much as possible.
[0032] Reference Figure 2-4 As shown in this embodiment: a circular block 26 is fixedly connected to one end of the L-shaped rod 25; a pressure sensor 28 is installed on one side of the inner wall of the liquid inlet pipe 6; and a warning light 211 is installed on one side of the top of the cup body 5. When the liquid level inside the cup body 5 rises, causing the circular rod 23 to close one end of the L-shaped hole 22, the circular rod 23 will drive the L-shaped rod 25 to move upward, causing one side of the circular block 26 to contact one side of the pressure sensor 28 and causing the pressure parameter of the pressure sensor 28 to change. The change is transmitted to the control system inside the cup body 5, which then activates the warning light 211. 1. The staff is prompted to activate the balancing device 2. Positioning grooves 29 are provided on both sides of the round rod 23. Positioning blocks 210 are fixedly connected to both sides of the bottom of the inner wall of the liquid inlet pipe 6. The positioning blocks 210 are located inside the positioning grooves 29. When the round rod 23 moves up and down, the positioning grooves 29 on both sides will slide on the outer surface of the positioning blocks 210. The positioning blocks 210 and positioning grooves 29 can further limit the angle between the float 24 and the cup body 5, and avoid the angle of the float 24 inside the cup body 5 as much as possible.
[0033] Reference Figure 1 , Figure 5 and Figure 6 As shown in this embodiment: a sealing device 3 is provided on the outer surface of the liquid inlet pipe 6. The sealing device 3 includes a sealing cylinder 33. A threaded ring 32 is fixedly connected to the bottom end of the sealing cylinder 33. A threaded groove 31 is opened on the outer surface of the liquid inlet pipe 6. The inner wall of the threaded ring 32 is threadedly connected to the outer surface of the liquid inlet pipe 6 with the threaded groove 31. When connecting the liquid inlet pipe 6 to the discharge pipe of the material box, the threaded ring 32 can be first put on the outer surface of the liquid inlet pipe 6. The sealing cylinder 33 is pushed to rotate and the threaded ring 32 is threadedly connected to the outer surface of the liquid inlet pipe 6 with the threaded groove 31. The sealing cylinder 33 is installed on the outside of the liquid inlet pipe 6. The connection between the liquid inlet pipe 6 and the discharge pipe of the material box is further sealed by the sealing cylinder 33, so as to avoid the liquid inside the material box from leaking out when passing through the connection between the discharge pipe and the liquid inlet pipe 6 as much as possible.
[0034] Reference Figure 5 and Figure 6 As shown in this embodiment: an annular strip 34 is fixedly connected to the top of the inner wall of the sealing cylinder 33. The annular strip 34 is made of rubber. By setting the annular strip 34 made of rubber, the outer side of the connection between the liquid inlet pipe 6 and the discharge pipe of the material box can be further sealed, thereby improving the sealing effect of the sealing device 3. Several protrusions 35 are fixedly connected to the outer surface of the threaded ring 32. The protrusions 35 are circumferentially distributed on the outer surface of the threaded ring 32. Holding the protrusions 35 on the outer surface of the threaded ring 32 makes it easier to push the threaded ring 32 to rotate and disassemble the sealing cylinder 33.
[0035] Working Principle: When producing capsules using a capsule machine, the cup body 5 is installed below the discharge port of the capsule machine's feed hopper through the mounting hole 4 on the outer surface of the cup holder 1. The threaded ring 32 is fitted onto the outer surface of the inlet pipe 6, and the sealing cylinder 33 is rotated to thread the threaded ring 32 onto the outer surface of the inlet pipe 6, which has a threaded groove 31. The sealing cylinder 33 is then installed on the outside of the inlet pipe 6, and the inlet pipe 6 is connected to the discharge port. Liquid from inside the feed hopper enters through the through hole 21 in the inlet pipe 6, passes through the L-shaped hole 22, and enters the interior of the cup body 5. It is then output through the outlet pipe 7 at the bottom of the cup body 5. Because the outlet pipe 7 is curved, the output rate of the liquid inside the cup body 5 through the outlet pipe 7 is less than the input rate at the inlet pipe 6. The liquid in the feed hopper continues to... As more liquid enters the cup body 5, the liquid level inside the cup body 5 rises. The float plate 24 pushes the round rod 23 to slide upward on the inner wall of the through hole 21, gradually closing one end of the L-shaped hole 22 inside the through hole 21. At the same time, one side of the round block 26 contacts one side of the pressure sensor 28, causing the pressure parameter of the pressure sensor 28 to change. The control system inside the cup body 5 will turn on the warning light 211 to remind the staff that the balancing device 2 is operating. When the liquid level inside the cup body 5 drops, the round rod 23 will move downward and gradually open one end of the L-shaped hole 22, allowing the liquid inside the tank to enter the cup body 5 through the L-shaped hole 22, thus keeping the liquid level inside the cup body 5 at a certain height as much as possible.
