Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical engineering technology, and more specifically, to an extrusion molding apparatus. Background Technology

[0002] The pharmaceutical industry is closely related to people's health and quality of life. The continuous discovery of new drugs and the great progress in treatment methods have brought about tremendous changes in the pharmaceutical industry. As a result, drugs are constantly being innovated. In the process of manufacturing drugs, the drug ratio needs to be determined in advance. During production, the drug powder is put into a tablet granulator for extrusion to obtain the finished product, which is then put into the market for sale. This is the most critical step in manufacturing drugs.

[0003] However, existing extrusion molding devices often encounter problems when the formed tablets get stuck inside the mold, making them difficult to remove. Using tools to reach into the mold and remove the tablets from the top can damage the tablet surface, leading to low yield, increased production volume, and higher material consumption. Therefore, an extrusion molding device has been developed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an extrusion molding device. The technical problem to be solved by the present invention is that the formed tablets are easy to get stuck inside the molding die and are difficult to remove. If a tool is used to penetrate into the molding die and take the tablet from the top, the surface of the tablet is easily damaged, resulting in low yield, increased production volume and increased material consumption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an extrusion molding device, comprising a bottom component, a middle component disposed on the top of the bottom component, and a feeding component disposed on the top of the middle component;

[0006] The feeding assembly includes a motor, with a rotating gear fixedly connected to the bottom output end of the motor. Racks mesh on both sides of the rotating gear, and a fixing strip is fixedly connected to one end of each rack. A pushing block is fixedly connected to the side of each fixing strip away from the rack. Multiple T-shaped sliders are fixedly connected to the bottom of each pushing block. Each pushing block has a storage chamber inside, and multiple inclined guide blocks are fixedly connected to the bottom of each storage chamber. A second lifting seat is provided on the side of each pushing block away from the motor. Multiple upper extrusion columns are fixedly connected to the bottom of each second lifting seat. Connecting sleeve columns are fixedly connected to both sides of the second lifting seat. A lead screw column is rotatably connected to the inner cavity of each connecting sleeve column, and a lead screw lifting machine body is rotatably connected to the bottom of each lead screw column.

[0007] In a preferred embodiment, the central component includes a functional plate with multiple feeding grooves on its surface and multiple mounting grooves through its top surface. A shaft disc is fixedly connected to the center of the top of the functional plate, and multiple T-shaped sliding grooves are provided on the top surface of the functional plate. A fixing frame is fixedly connected to the center of the top of the functional plate. A forming block is provided in each mounting groove, and multiple forming cavities are through its surface.

[0008] In a preferred embodiment, the bottom assembly includes a base, a plurality of brackets are fixedly connected to the top of the base, collection frames are provided on both sides of the base, a plurality of first lifting seats are provided on the top of the base, telescopic rods are fixedly connected to both sides of the first lifting seats, telescopic seats are sleeved on the bottom of the telescopic rods, and a plurality of downward squeezing columns are fixedly connected to the top of the first lifting seats.

[0009] In a preferred embodiment, the bottom of the rotating gear is fixedly connected to the shaft disk, and the bottom of the push block has a material passage groove with the same number and inner diameter as the forming cavity.

[0010] In a preferred embodiment, the T-shaped slider is disposed within a T-shaped groove, and the motor is disposed on top of the fixed frame.

[0011] In a preferred embodiment, the lower extrusion column and the upper extrusion column have the same inner diameter as the molding cavity, and when the telescopic rod and the telescopic seat are raised to the maximum position, the top of the lower extrusion column is at the same height as the top of the molding block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model comprises a bottom component, a feeding component, and a middle component. In use, the medicine powder is first poured directly into the storage chamber. After the motor is started, it drives the rack to move. As the rack moves, the pushing block moves along the T-shaped groove via a T-shaped slider. When the bottom feed groove of the pushing block connects with the forming cavity, the medicine powder falls directly into the forming cavity. After the rack retracts the pushing block, the screw jack lowers the height of the second lifting seat, causing the upper extrusion column to press against the forming cavity. Then, the screw jack raises the height of the second lifting seat. After the telescopic rod is raised by the telescopic seat, the top of the lower extrusion column is aligned with the top of the forming block. Then, the rack drives the push block to move outward along the T-shaped slide groove via the T-shaped slider. The formed pill is pushed out of the functional plate surface by the bottom of the outer surface of the push block and falls into the collection box. This solves the problem that the formed tablets are easy to get stuck inside the forming mold and difficult to remove. If tools are used to go deep into the forming mold and take the tablet from the top, the surface of the tablet is easily damaged, resulting in low yield, increased production volume and increased material consumption.

[0014] 2. This utility model, by providing a forming cavity, a lower extrusion column, and an upper extrusion column, allows for direct control of the pill powder content during later use by adjusting the height of the upper extrusion column within the forming cavity. The extrusion between the lower and upper extrusion columns directly compresses the pill powder into a pill shape, thus improving the controllability of the pill content. Attached Figure Description

[0020] 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.

[0021] This utility model provides an extrusion molding device, including a bottom component 1, a middle component 3 disposed on the top of the bottom component 1, and a feeding component 2 disposed on the top of the middle component 3;

[0022] The feeding assembly 2 includes a motor 21. A rotating gear 22 is fixedly connected to the bottom output end of the motor 21. A rack 23 meshes with both sides of the rotating gear 22. A fixing strip 24 is fixedly connected to one end of each rack 23. A pushing block 25 is fixedly connected to the side of the fixing strip 24 away from the rack 23. Multiple T-shaped sliders 26 are fixedly connected to the bottom of each pushing block 25. A storage cavity 27 is opened in the inner cavity of each pushing block 25. Multiple inclined guide blocks 28 are fixedly connected to the bottom of each storage cavity 27. A second lifting seat 29 is provided on the side of each pushing block 25 away from the motor 21. Multiple upper extrusion columns 210 are fixedly connected to the bottom of each second lifting seat 29. Connecting sleeve columns 211 are fixedly connected to both sides of the second lifting seat 29. A lead screw column 212 is rotatably connected to the inner cavity of each connecting sleeve column 211. A lead screw lifting body 213 is rotatably connected to the bottom of each lead screw column 212.

[0023] The middle component 3 includes a functional plate 31. Multiple material feeding grooves 32 are formed on the surface of the functional plate 31. Multiple mounting grooves 33 are formed through the top surface of the functional plate 31. A shaft disk 34 is fixedly connected to the center of the top of the functional plate 31. Multiple T-shaped sliding grooves 35 are formed on the top surface of the functional plate 31. A fixing frame 36 is fixedly connected to the center of the top of the functional plate 31. A forming block 37 is provided in each mounting groove 33. Multiple forming cavities 38 are formed through the surface of the forming block 37.

[0024] The bottom component 1 includes a base 11, with multiple brackets 12 fixedly connected to the top of the base 11. Collection frames 13 are provided on both sides of the base 11. Multiple first lifting seats 14 are provided on the top of the base 11. Telescopic rods 15 are fixedly connected to both sides of the first lifting seats 14. Telescopic seats 16 are sleeved at the bottom of each telescopic rod 15. Multiple lower extrusion columns 17 are fixedly connected to the top of the first lifting seats 14.

[0025] Among them, the bottom of the rotating gear 22 is fixedly connected to the shaft disk 34, and the bottom of the push block 25 has a material passage groove with the same number and inner diameter as the forming cavity 38; in later use, it can make the overall equipment run more smoothly.

[0026] The T-shaped slider 26 is set inside the T-shaped groove 35, and the motor 21 is set on the top of the fixed frame 36; this allows for more space to install and use the various components during use.

[0027] The lower extrusion column 17 and the upper extrusion column 210 have the same inner diameter as the forming cavity 38. When the telescopic rod 15 and the telescopic seat 16 are raised to the maximum position, the top of the lower extrusion column 17 is at the same height as the top of the forming block 37. This avoids the lower extrusion column 17 blocking the push block 25 due to the accuracy of the lifting control of the telescopic rod 15 and the telescopic seat 16, which would affect the final material discharge.

[0028] Working principle of this utility model:

[0029] In use, the medicine powder is first poured directly into the storage chamber 27. After the motor 21 is started, it drives the rack 23 to move. When the rack 23 moves, the push block 25 can move along the T-shaped slide groove 35 through the T-shaped slider 26. When the bottom passage of the push block 25 is connected to the forming chamber 38, the medicine powder will fall directly into the forming chamber 38. After the rack 23 retracts the push block 25, the screw jack 213 is started to lower the height of the second lifting seat 29, so that the upper extrusion column 210 presses into the forming chamber 38. Then, the screw jack 213 raises the height of the second lifting seat 29. After the retractable seat 16 raises the telescopic rod 15, ensuring the top of the lower extrusion column 17 is level with the top of the forming block 37, the rack 23 drives the push block 25 to move outward along the T-shaped slide groove 35 via the T-shaped slider 26. The formed pill is pushed out of the functional plate 31 by the bottom of the outer surface of the push block 25 and falls into the collection box 13. This solves the problem of formed tablets easily getting stuck inside the forming mold and being difficult to remove. If tools are used to reach into the forming mold and remove the tablet from the top, the surface of the tablet is easily damaged, resulting in low yield, increased production volume, and increased material consumption. Furthermore, in later use, the height of the upper extrusion column 210 within the forming cavity 38 can be directly controlled to adjust the powder content of the pills. The extrusion between the lower extrusion column 17 and the upper extrusion column 210 directly compresses the powder into pills, improving the controllability of the pill content.
