Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical tablet production technology, and in particular to a tablet press for producing Propsys tablets. Background Technology
[0002] Prostatin tablets are a medication used to treat benign prostatic hyperplasia and chronic, nonbacterial prostatitis. The production process of Prostatin tablets involves compressing the powder into tablets, which requires a tablet press. The tablet press's workflow typically includes three main steps: filling, compression, and tablet ejection. The drug powder or granules are filled into a mold, and the material is compressed using upper and lower punches to form tablets of the desired shape and thickness. The compressed tablets are then ejected from the mold.
[0003] However, tablet presses generate dust during the compression molding process of powdered drugs. This dust may affect the cleanliness of the working environment and may even affect the health of operators. Furthermore, if the air contained in the granules is not expelled in time during compression, the elastic recovery may cause the tablets to crack when the pressure is released after compression is completed. Utility Model Content

[0029] Example 1
[0030] Reference Figure 1 -5, the first embodiment of this utility model, provides a tablet press for producing Prostat tablets, the structure of which includes:
[0031] The main unit 100 includes an operating table 101, on which a powder storage box 102 is fixed. The powder storage box 102 is provided with a feeding port 103, and a solenoid valve 104 is installed on the feeding port 103. During use, the powder is put into the powder storage box 102, and the solenoid valve 104 is opened to allow the powder to enter the dispensing chamber from the feeding port 103. Then, the powder is moved by the conveying unit 300 and pressed into tablets.
[0032] The dust extraction unit 200 includes a dust extraction box 201, which is mounted on the operating table 101. A servo motor 202 is mounted on one side of the dust extraction box 201. The output end of the servo motor 202 is connected to a drive sprocket 203. A fan blade 204 is mounted on one side of the drive sprocket 203. The fan blade 204 is covered by a filter screen 205, which is installed inside the dust extraction box 201. A dust extraction port 206 is mounted on the other side of the dust extraction box 201. During use, the servo motor 202 is started to rotate the drive sprocket 203. The drive sprocket 203 drives the fan blade 204 on one side to rotate and exhaust the air in the dust extraction box 201, so that a low-pressure area is formed around the fan blade 204. This low-pressure area causes the excess dust generated during the tableting process to be sucked into the dust extraction box 201 by the dust extraction port 206.
[0033] The conveying unit 300 includes a conveying roller 301. A first conveyor belt 302 and a second conveyor belt 303 are fitted onto the surface of the conveying roller 301. Both the first and second conveyor belts 302 and 303 have through grooves. A spring 304 is fixed inside the through groove, and a push rod 305 is inserted into the spring 304. A piston 306 is fixed to one end of the push rod 305. During operation, power is transmitted through a chain 2031, causing the driven sprocket 2032 to rotate along with the drive sprocket 203, thereby rotating the conveying roller 301. This, in turn, drives the first and second conveyor belts 302 and 303 to convey the powder forward. When the device moves to the connection between the first cavity and the second cavity, the first drive wheel 1011 and the second drive wheel 1012 can push the push rod 305 forward, causing the piston 306 to be pushed into the through groove on the first conveyor belt 302, compressing the powder into tablets. Through the pre-compression of the first drive wheel 1011 and the secondary compression of the second drive wheel 1012, the air content in the powder can be reduced, thereby reducing the cracking phenomenon. The first conveyor belt 302 and the second conveyor belt 303 continue to transport the tablets forward to the discharge port. The push rod 305 is pushed by the inner wall of the first cavity, causing the piston 306 to push the tablets down, which fall into the drawer 1013 for easy collection of the finished tablets.
[0034] Furthermore, the operating table 101 has a first cavity and a second cavity inside, and the first conveyor belt 302 and the second conveyor belt 303 are respectively installed in the first cavity and the second cavity. The first conveyor belt 302 and the second conveyor belt 303 are installed through the first cavity and the second cavity.
[0035] Furthermore, a material distribution chamber is also provided on one side of the first cavity. The bottom of the discharge port 103 is installed in the material distribution chamber. The powder falls into the material distribution chamber through the discharge port 103 and enters the through groove on the first conveyor belt 302.
[0036] Furthermore, the first cavity and the second cavity are respectively equipped with a first drive wheel 1011 and a second drive wheel 1012. Through the pre-compression of the first drive wheel 1011 and the secondary compression of the second drive wheel 1012, the air content in the powder can be reduced, thereby reducing the phenomenon of top cracking.
[0037] Furthermore, a discharge port is provided on the inner wall of the end of the first cavity, and a drawer 1013 is installed below the discharge port. When the tablet moves to the discharge port, the push rod 305 is pushed through the inner wall of the first cavity, causing the piston 306 to push the tablet down and into the drawer 1013 for easy collection of the finished tablet.
[0038] Furthermore, a chain 2031 is engaged with the surface of the drive sprocket 203, and a driven sprocket 2032 is engaged with the chain 2031. The driven sprocket 2032 is installed at one end of the conveyor roller 301, and power is transmitted through the chain 2031, so that the driven sprocket 2032 drives the conveyor roller 301 to rotate as the drive sprocket 203 rotates.
[0039] During use, the servo motor 202 is first started to make the drive sprocket 203 rotate. The drive sprocket 203 drives the fan blade 204 on one side to rotate and exhaust the air in the dust collection box 201, so that a low-pressure area is formed around the fan blade 204. This low-pressure area causes the excess dust generated during the tableting process to be sucked into the dust collection box 201 by the dust collection port 206.
[0040] Then, the powder is put into the powder storage box 102, and the solenoid valve 104 is opened to allow the powder to enter the distribution chamber from the feed port 103. Power is transmitted through the chain 2031, causing the driven sprocket 2032 to drive the conveyor roller 301 to rotate as the drive sprocket 203 rotates. This, in turn, drives the first conveyor belt 302 and the second conveyor belt 303 to convey the powder forward. When the first conveyor belt 302 and the second conveyor belt 303 move to the part where the first cavity and the second cavity connect, the first drive wheel 1011 and the second drive wheel 1012 can push the push rod 305 forward, so that the piston 306 is pushed into the through groove on the first conveyor belt 302, pressing the powder into tablets.
[0041] Finally, the air content in the powder can be reduced by the pre-compression of the first drive wheel 1011 and the secondary compression of the second drive wheel 1012, thereby reducing the cracking phenomenon. The first conveyor belt 302 and the second conveyor belt 303 continue to transport the tablets forward to the discharge port. The push rod 305 is pushed by the inner wall of the first cavity, causing the piston 306 to push the tablets down and fall into the drawer 1013 for easy collection of the finished tablets.
[0042] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
