Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a stamping device for controllable porosity of sustained-release tablet core material. Background Technology

[0002] Tablet porosity is an important physical parameter of pharmaceutical preparations, which refers to the ratio of the volume of pores inside the tablet to the total volume. It directly affects the disintegration, dissolution and bioavailability of the drug.

[0003] In the process of developing new drugs in the laboratory, porosity is an important indicator of tablets. By changing the pressure, the porosity of the tablets can be different. When conducting comparative experiments on multiple groups of materials, it is necessary to continuously change the pressure parameters or change different dies for pressing. CNC pressing is set by input data, which requires numerical input settings, and the operation is cumbersome and costly. Changing the die is cheaper, but the repeated disassembly and assembly is complicated. Therefore, we propose a stamping device for controllable porosity of sustained-release tablet core material.

The spring is movably sleeved on the movable rod and provides an upward oblique force on the movable rod. Multiple pressure columns arranged in a ring are fixedly connected to the other side of the conversion platform, with the length of each pressure column gradually increasing. A pressure head for pressing powder is fixedly connected to the end of each pressure column.

[0007] A demolding assembly includes a fixing groove, a base fixedly connected inside the fixing groove, a forming groove for powder compression molding on the top of the base, a top block movably fitted onto the inner wall of the forming groove, a lifting groove on one side of the operating table that passes through the operating table and the base and extends into the forming groove, a connecting rod fixedly connected to the side surface of the top block, the connecting rod being C-shaped, and one end of the connecting rod being movably connected to the lifting groove, a pull ring fixedly connected to the top of the connecting rod, and a fixing plate fixedly connected to the top of the conversion column, the fixing plate being located at the bottom of the pull ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the stamping device allows for controllable porosity of the slow-release tablet core material.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model embodiment provides a stamping device with controllable porosity of the slow-release tablet core material, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes an operating console 1;

[0024] Switching component 2 includes a conversion column 201. The bottom surface of the conversion column 201 is obliquely cut at a 45-degree angle to the horizontal plane. Multiple slots 202 are formed on the bottom cut surface of the conversion column 201. A conversion platform 203 is movably connected to the cut surface of the conversion column 201. One side of the conversion platform 203 is fixedly connected to a number of protrusions 204 equal to the number of slots 202, and the protrusions 204 are engaged in the slots 202. A movable rod 205 is fixedly connected to the center position of one side of the conversion platform 203. The other end of the movable rod 205 is fixed. A limiting plate 206 is connected to the side surface of the conversion column 201, and a clearance groove 210 is provided. A spring 207 is movably connected to one side of the limiting plate 206 and the inner wall of one side of the clearance groove 210. The spring 207 is movably sleeved on the movable rod 205 and provides a force on the movable rod 205 to move obliquely upward. A plurality of pressure columns 208 arranged in a ring are fixedly connected to the other side of the conversion table 203, and the length of each pressure column 208 gradually increases. A pressure head 209 for pressing powder is fixedly connected to the end of the pressure column 208.

[0025] The demolding assembly 3 includes a fixing groove 301, a base 307 fixedly connected inside the fixing groove 301, a molding groove 308 for powder compression molding opened on the top of the base 307, a top block 302 movably sleeved on the inner wall of the molding groove 308, a lifting groove 303 opened on one side of the operating table 1 and the lifting groove 303 sequentially passing through the operating table 1 and the base 307 and extending into the molding groove 308, a connecting rod 304 fixedly connected to the side surface of the top block 302, the connecting rod 304 is C-shaped, and one end of the bottom of the connecting rod 304 is movably connected in the lifting groove 303, a pull ring 305 fixedly connected to the top of the connecting rod 304, and a fixing plate 306 fixedly connected to the top of the conversion column 201, the fixing plate 306 being located at the bottom of the pull ring 305.

[0026] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a support 4 is fixedly connected to the top of the operating table 1, and a hydraulic press 5 is fixedly connected to the top of the support 4. The output end of the hydraulic press 5 is movably connected through the support 4. During use, the equipment is first initialized and restored to its default state. Then, powder is filled into the forming groove 308, and excess powder is scraped off using a leveling tool to make the top of the forming groove 308 flat. Next, the hydraulic press 5 is started, and the output end of the hydraulic press 5 extends downwards to its limit. At this time, the powder in the forming groove 308 is gradually pressed by the pressure head 209, causing the powder to be compressed into tablets. Then, the hydraulic press 5 is started again, causing the output end of the hydraulic press 5 to rise upwards until it contracts to its limit. During the upward movement, the fixed plate 306 moves upwards and pulls the pull ring 305, causing the top block 302 to push the compressed tablets out of the forming groove 308, achieving demolding. The experimenter removes the tablets and restores the equipment to its default state. The force exerted on the tablet is adjusted by changing the pressure column 208 of different lengths to obtain the tablet porosity under different pressures, facilitating subsequent observation and research. When changing the pressure column 208, the conversion platform 203 is first pulled diagonally downwards against the force of the spring 207, causing the protrusion 204 on the conversion platform 203 to disengage from the slot 202 on the cross-section of the pressure column 208, thus engaging. Then, the conversion platform 203 is rotated so that the pressure column 208 of the required length is rotated to the bottom and is in a vertical position. Since the position of the protrusion 204 corresponds to that of the pressure column 208, the position of the protrusion 204 corresponds to that of the slot 202. Then, the force exerted diagonally downwards on the conversion platform 203 is released, so that the force of the spring 207 provides an upward force on the conversion platform 203, causing the protrusion 204 to engage again in the slot 202, thus completing the switching of different pressure columns 208.

[0027] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the fixed plate 306 is fixedly connected to the output end of the hydraulic press 5, and the pull ring 305 is movably sleeved on the side surface of the output end of the hydraulic press 5.

[0028] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the protrusion 204 is engaged in the slot 202 by the force of the spring 207. The switching platform 203 can move axially along the movable rod 205 to release the engagement between the protrusion 204 and the slot 202. The switching platform 203 can rotate around the axis of the movable rod 205 to switch the pressure column 208 of different lengths to a vertical state. Through the switching component 2, the pressure column 208 of different lengths can be quickly replaced. After the output end of the hydraulic press 5 extends to its limit, the pressure of the powder to be pressed into tablets can be changed by switching the pressure column 208 of different lengths, thereby obtaining the porosity of the tablets under different pressures. This makes it convenient to understand the porosity of different experimental powders under different pressures, and facilitates the understanding of multiple sets of experimental data during the experiment. Furthermore, the spring 207 engages the protrusion 204 in the slot 202, allowing for quick switching between the pressure head 209 and the pressure column 208 without disassembling the pressure head 209, thus improving the convenience of operation and improving the efficiency of operation during the experiment.

[0029] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the output end of the hydraulic press 5 is fully extended, the pressure head 209 presses into the forming groove 308. When the output end of the hydraulic press 5 is fully retracted, the pull ring 305 can be lifted by the fixing plate 306.

[0030] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the pull ring 305 is pulled upward, the top block 302 moves upward with the connecting rod 304, pushing the powder-pressed tablet out of the forming groove 308. Through the demolding assembly 3, the output end of the hydraulic press 5 is raised to its limit, and the pull ring 305 and the connecting rod 304 are pulled by the fixing plate 306, causing the top block 302 to push the pressed tablet out of the mold. Thus, pressing and demolding are integrated, and operation continuity is provided, which further improves operation efficiency and provides operation convenience. Moreover, the equipment is mainly mechanical structure, which is low in cost and highly reliable.

[0031] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the bottom of the top block 302 moves to its limit under the action of gravity, the output end of the hydraulic press 5 is at the default initial position. The height of the top block 302 is less than the height of the forming groove 308, and the height of the top block 302 is higher than the height of the lifting groove 303.

[0032] Working principle: When using the equipment, first initialize it and restore it to the default state. Then, fill the molding tank 308 with powder and use a scraper to remove excess powder, making the top of the molding tank 308 flat. Next, start the hydraulic press 5. The output end of the hydraulic press 5 extends downward to its limit. At this time, the powder in the molding tank 308 is gradually pressed by the pressure head 209, making the powder into tablets. Then, start the hydraulic press 5 again, making the output end of the hydraulic press 5 rise upward until it contracts to its limit. During the upward movement, the fixed plate 306 moves upward and pulls the pull ring 305, so that the top block 302 pushes the pressed tablets out of the molding tank 308, realizing demolding. The experimenter removes the tablets and restores the equipment to the default state.

[0033] The force exerted on the tablets can be adjusted by changing the length of the pressure column 208 as needed, thereby obtaining the tablet porosity under different pressures, which facilitates subsequent observation and research. When changing the pressure column 208, firstly, the conversion platform 203 is pulled diagonally downwards against the force of the spring 207, so that the protrusion 204 on the conversion platform 203 disengages from the slot 202 on the cross-section of the pressure column 208, thus making contact and engagement. Then, the conversion platform 203 is rotated so that the pressure column 208 of the required length is rotated to the bottom and is in a vertical position. Since the position of the protrusion 204 corresponds to that of the pressure column 208, the position of the protrusion 204 corresponds to that of the slot 202. Then, the force exerted diagonally downwards on the conversion platform 203 is released, so that the force of the spring 207 provides an upward force on the conversion platform 203, so that the protrusion 204 is engaged in the slot 202 again, thus completing the switching of different pressure columns 208.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
