Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical compression molding, and particularly relates to a pharmaceutical compression molding device. Background Art

[0002] Tablets are one of the common types of pharmaceuticals. When they are prepared, the pharmaceutical ingredients are prepared into powder, and then the powder is extruded using a mold to form a sheet-like pharmaceutical.

[0003] Chinese Patent Publication No. CN117429114B discloses a pharmaceutical compression molding device, including a fixed seat and a feeding part. The inner wall of the fixed seat is fixedly embedded with a template. The top and bottom of the fixed seat are respectively slidably fitted with a first lifting plate and a second lifting plate through linear slide rails. A plurality of stamping channels are opened in the inner wall of the template. An upper punch is fixed on the lower surface of the first lifting plate above the stamping channels, and a lower punch is arranged on the upper side of the second lifting plate below the stamping channels. The lower punch includes a blanking cylinder fixedly connected to the inner wall of the bottom of the template through a rotating ring. In the present invention, the lower punch is set as a combination of a blanking cylinder and a plurality of fan-shaped pieces. During pressing, the plurality of fan-shaped pieces approach and close to each other to form a pressing support surface. After pressing, they move away from each other to open the channel, so that the tablets are discharged by gravity, thus ensuring the reliability of discharging on the basis of automatic discharging.

[0004] However, the above device is exposed to the air during use. Without a protective cover, operators may directly contact moving mechanical components, thus increasing the risk of injury. Without the isolation of a protective cover, pharmaceutical raw materials and tablets are easily contaminated by the environment, which may cause the tablets to be contaminated and affect the quality and safety of pharmaceuticals. At the same time, the device is not provided with a device for sucking dust from the excess powder on the pharmaceuticals after pressing and shaping. Failure to remove the excess powder may lead to inconsistent weights and dosages of the tablets, affecting the efficacy and safety of the drugs, and the uncollected powder may spread into the working environment, affecting the air quality and possibly causing respiratory health problems for the staff. Therefore, to solve the above problems, a pharmaceutical compression molding device is proposed. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a pharmaceutical compression molding device with high practicability, which can be operated simply and has a relatively simple structure.

[0006] To solve the above technical problems, a medicine pressing and forming device provided by the utility model includes: support columns fixed at the bottom of a workbench, a support frame fixed at the top of the workbench, and a hydraulic device with a downward outlet fixed at the exact middle position above the support frame. The hydraulic device is fixed above the workbench through the support frame. A protection mechanism is fixed at the bottom of the hydraulic device, and a dust suction mechanism is arranged on the protection mechanism. The protection mechanism and the dust suction mechanism move up and down along with the hydraulic device. A mold is placed above the workbench, and an installation groove matching the mold is formed above the workbench. The mold can move along the installation groove on the workbench. A fixing block for fixing the position of the mold is arranged above the workbench directly below the hydraulic device.

[0007] As a further scheme of the utility model, the protection mechanism includes limit blocks, sliders and a dust-proof cover. Two groups of the limit blocks are fixed on the left and right sides of the hydraulic device.

[0008] As a further scheme of the utility model, the slider is of a T-shaped structure, and a T-shaped sliding groove matching the slider is formed in the limit block, so that the slider can slide in the limit block.

[0009] As a further scheme of the utility model, the upper end of the dust-proof cover is movably clamped in the limit block through the slider. The dust-proof cover and the limit block form an embedded sliding connection through the slider. When the hydraulic device continuously descends, the dust-proof cover moves upward through the slider, which can prevent the dust-proof cover from blocking the work of the hydraulic device.

[0010] As a further scheme of the utility model, the dust suction mechanism includes a dust suction fan, a dust suction pipe, a dust discharge pipe and a dust accumulation bucket. The dust suction pipe and the dust discharge pipe are both made of flexible materials that can be bent and can move along with the hydraulic device, increasing the flexibility of the device.

[0011] As a further scheme of the utility model, one side of the dust suction pipe is connected to the dust suction fan, and the other side passes through a pipe passing hole on the support frame and is installed on the dust-proof cover and is communicated with the inside of the dust-proof cover, which can capture powder more effectively and reduce the diffusion of powder in the working environment.

[0012] As a further scheme of the utility model, the two fixing blocks are inserted on the left and right sides of the hydraulic position of the hydraulic device, so as to fix the position of the mold that needs to press and form medicine and is slidably connected to the workbench, and fix the position of the mold to avoid damage to the device caused by incorrect placement.

[0013] Compared with the related technology, a medicine pressing and forming device provided by the utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a protection mechanism on the hydraulic device. The dust cover is movably clamped in the limit block through a slider. When the hydraulic device continuously descends, the dust cover moves upward through the slider, which can prevent the dust cover from blocking the operation of the hydraulic device. The dust cover can prevent the operator from directly contacting the moving hydraulic device, thereby reducing the risk of injury. Moreover, by restricting the diffusion of powder, the dust cover improves the air quality of the entire working environment, makes the workplace safer and more comfortable, effectively prevents the operator from inhaling drug powder, protects the health of their respiratory system, reduces the risk of occupational diseases, and the dust cover reduces the possibility of the tablets contacting pollutants in the external environment, reducing the risk of drug contamination and ensuring product quality.

[0015] 2. The utility model is provided with a dust suction mechanism on the protection mechanism. By being installed on the dust cover, it performs local dust prevention on the die position below the hydraulic device, enabling the dust suction pipe to be closer to the position of the powder, thereby more effectively capturing the powder and reducing the diffusion of the powder in the working environment. By sucking away the excess powder, it can prevent this powder from causing cross-contamination during the pressing process or affecting the accurate dosage of the tablets, ensuring that each tablet contains accurate and consistent active ingredients and meeting the strict standards of drug production. The dust suction mechanism can work continuously without affecting production, reducing the downtime caused by cleaning and maintenance, being able to clean the powder on the tablet surface in a timely manner, avoiding additional cleaning work before subsequent processing, thereby improving the overall production efficiency. Effective dust suction can reduce the powder accumulation in the pressing area, thereby reducing the cleaning and maintenance frequency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0023] Please refer to Figures 1-5 , a drug pressing and forming device, comprising: a support column 2 fixed to the bottom of the workbench 1, a support frame 3 fixed to the top of the workbench 1, and a hydraulic device 4 with a downward outlet fixed at the middle position directly above the support frame 3. The hydraulic device 4 is fixed above the workbench 1 through the support frame 3. A protection mechanism 8 is fixed to the bottom of the hydraulic device 4, and a dust suction mechanism is arranged on the protection mechanism 8. The protection mechanism 8 and the dust suction mechanism move up and down with the hydraulic device 4. A mold 6 is placed above the workbench 1, and an installation groove 5 matching the mold 6 is opened above the workbench 1. The mold 6 can move on the workbench 1 along the installation groove 5. A fixing block 7 for fixing the position of the mold 6 is arranged above the workbench 1 directly below the hydraulic device 4.

[0024] The protection mechanism 8 includes a limit block 81, a slider 82 and a dust-proof cover 83. Two groups of limit blocks 81 are fixed on the left and right sides of the hydraulic device 4. The slider 82 is of a T-shaped structure, and a T-shaped sliding groove matching the slider 82 is opened in the limit block 81. The upper end of the dust-proof cover 83 is movably clamped in the limit block 81 through the slider 82. The dust-proof cover 83 is connected with the limit block 81 in an embedded sliding manner through the slider 82. When the hydraulic device 4 continuously descends, the dust-proof cover 83 moves upward through the slider 82, which can prevent the dust-proof cover 83 from blocking the operation of the hydraulic device 4. By providing the dust-proof cover 83 installed on the hydraulic device 4, partial isolation and protection are carried out on the polishing part of the hydraulic device 4, avoiding direct contact between the operator and the moving hydraulic device 4, thereby reducing the risk of injury. And by restricting the diffusion of powder through the dust-proof cover 83, the possibility of the tablets contacting pollutants in the external environment is reduced, and the air quality of the entire working environment is improved.

[0025] The dust collection mechanism includes a dust collection fan 9, a dust collection pipe 10, a dust discharge pipe 11 and a dust accumulation bucket 12. Both the dust collection pipe 10 and the dust discharge pipe 11 are made of flexible materials that can be bent. One side of the dust collection pipe 10 is connected to the dust collection fan 9, and the other side passes through the pipe through-hole 13 on the support frame 3 and is installed on the dust-proof cover 83, and is in communication with the inside of the dust-proof cover 83. Two fixing blocks 7 are inserted on the left and right sides of the hydraulic position of the hydraulic device 4, so as to fix the position of the mold 6 that needs to press the medicine into shape and is slidably connected to the workbench 1. After the pressing is completed by the hydraulic device 4, through the dust-proof cover 83 installed on the hydraulic device 4, the mold 6 below the hydraulic device 4 is locally isolated, so that the dust collection pipe 10 can be closer to the powder, thereby more effectively capturing the powder inside the dust-proof cover 83, reducing the diffusion of the powder in the working environment. By sucking away the excess powder, it is possible to prevent these powders from causing cross-contamination or affecting the precise dosage of the tablets during the pressing process, avoiding additional cleaning work before subsequent processing, thereby improving the overall production efficiency.

[0026] The working principle of a medicine tablet pressing and forming device provided by the present utility model is as follows:

[0027] Ensure the cleanliness of the dust-proof cover 83 and the workbench 1, select a suitable mold 6 according to the shape and size of the required medicine, and prepare multiple molds 6 to improve work efficiency.

[0028] Fill the medicine powder into the mold 6, place the processed mold 6 inserted into the workbench 1 from the installation groove 5, and move the mold 6 to the position below the hydraulic device 4, and use the fixing block 7 to fix the mold 6.

[0029] Set the intensity of the dust collection fan 9 according to the characteristics of the pressing material, press the start button, and the hydraulic device 4 starts to move downward. When the hydraulic device 4 continues to descend, the dust-proof cover 83 moves upward through the slider 82, which can prevent the dust-proof cover 83 from blocking the work of the hydraulic device 4. Through the dust-proof cover 83 installed on the hydraulic device 4, the grinding part of the hydraulic device 4 is locally isolated and protected, preventing the operator from directly contacting the moving hydraulic device 4, thereby reducing the risk of injury, and by restricting the diffusion of the powder.

[0030] After the pressing is completed, the hydraulic device 4 slowly rises, and stops rising when the bottom of the hydraulic device 4 leaves the mold 6 and the dust-proof cover 83 does not leave the workbench 1. After the pressing is completed by the hydraulic device 4, the dust-proof cover 83 locally isolates the mold 6 below the hydraulic device 4, so that the dust collection pipe 10 can more effectively capture the powder inside the dust-proof cover 83, reduce the diffusion of the powder in the working environment, and suck away the excess powder to ensure the precise dosage of the tablets.

[0031] After production is completed, the hydraulic device 4 rises and returns to the starting position, pulls out the fixing block 7 on the workbench 1, slides the mold 6 out of the workbench 1 along the installation groove 5, installs another prepared mold 6 on the workbench 1 and fixes it, and prepares the next mold 6 to be pressed during the pressing process.

[0032] Regularly check the working condition of the dust suction mechanism to ensure that the powder is effectively sucked away. Check the amount of dust in the dust collection bucket 12 and clean or replace it if necessary. After completing the production task, stop feeding the machine. Wait until all the remaining materials have been pressed, then turn off the machine and thoroughly clean the device.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention, or directly or indirectly applied. In other related technical fields, the scope of the present invention is defined by the appended claims and their equivalents, and all are equally included in the patent protection scope of the present invention.
