Description

Technical Field

[0001] This utility model relates to the field of tablet processing technology, specifically to a device for forming rheumatism and bone pain tablets. Background Technology

[0002] Rheumatism and Bone Pain Tablets are a widely used medicine in the medical field for treating pain in the hands, feet, limbs, waist and spine caused by cold and dampness, as well as rheumatoid arthritis. The common form of Rheumatism and Bone Pain Tablets is tablets. This dosage form is made by applying pressure to the drug powder through a specific extrusion molding device to form it into a solid preparation. In the actual production process, Rheumatism and Bone Pain Tablets are initially produced in powder form. In order to facilitate storage and transportation, they are usually prepared into tablets, which requires the use of a tablet press.

[0003] According to announcement number CN221366000U, a water purification and disinfection tablet forming device belongs to the technical field of tablet forming devices. It includes: a base, a tablet pressing base on the base, a tablet release device on the tablet pressing base, a tablet collection channel inside the base, a tablet collection box inside the base, and multiple guide columns on the base. A pressure device moves vertically along the guide columns. By adding a tablet pressing groove to the tablet pressing base, the size of the pressed tablets can be limited. By adding a pressure device, pressure can be applied to the pressing groove to compress powdered medicine into tablets. By adding a tablet release device, the pressed tablets can be released after compression, and the tablets are collected by the tablet collection box.

[0004] As described above, although the processing efficiency of the tablets is improved during the molding process, floating powder remains on the surface of the rheumatism and bone pain tablets after compression molding. This floating powder may contain easily oxidized and highly hygroscopic components. After adhering to the tablet surface, it increases the contact area between the drug and air and moisture, thereby accelerating the oxidation, hydrolysis and other chemical reactions of the drug components. This leads to a decrease in the content of the effective ingredients, a shortened shelf life, and a reduction in drug quality, which affects the health of patients. In order to solve the above problems, an improved rheumatism and bone pain tablet molding device has been proposed. Utility Model Content

[0024] 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.

[0025] This utility model provides, for example Figures 1-5The apparatus shown includes a rheumatism and bone pain tablet forming device, comprising a mounting frame 1 and a worktable 2. A pressing assembly 3 is disposed between the top of the mounting frame 1 and the upper surface of the worktable 2. Material guiding mechanisms 4 are disposed on both sides of the mounting frame 1. The pressing assembly 3 is used to press and form the rheumatism and bone pain tablets, and the material guiding mechanisms 4 are used to guide the powdered raw material. A top-feeding assembly 5 is disposed in the inner cavity of the worktable 2, and the top-feeding assembly 5 is used to provide top material for the formed rheumatism and bone pain tablets. Sliding modules 6 are disposed on both sides of the worktable 2. The surface of the sliding module 6 is equipped with a cleaning device 7, which is used to clean the floating powder remaining on the surface of the formed rheumatism and bone pain tablets. The pressing assembly 3 includes a hydraulic cylinder 31, which is installed on the top of the mounting frame 1. The piston rod of the hydraulic cylinder 31 passes through the mounting frame 1 and is fixedly connected to the upper mold 32. The upper surface of the worktable 2 is fixedly connected to the lower mold 33, which is used in conjunction with the upper mold 32. The front end of the lower mold 33 is provided with a discharge groove, and the position of the discharge groove is integrally formed with a feeding plate 34.

[0026] First, the feeding mechanism 4 conveys the powdered raw material to the cavity of the lower mold 33 installed on the workbench 2. Then, the hydraulic cylinder 31 in the pressing assembly 3 pushes the upper mold 32 downward through the piston rod, cooperating with the lower mold 33 fixed on the workbench 2 to press and shape the raw material between them. After pressing and shaping, the rheumatism and bone pain tablets are ejected from the lower mold 33 by the ejector assembly 5. At the same time, the sliding modules 6 on both sides of the workbench 2 drive the cleaning device 7 to move and clean the floating powder on the surface of the formed rheumatism and bone pain tablets. After cleaning, the rheumatism and bone pain tablets can be quickly removed from the surface of the lower mold 33 by the operator with the help of an external scraper. During the removal process, the upper end of the ejector assembly 5 is kept horizontal with the surface of the lower mold 33. Therefore, the integrated process of feeding, pressing and shaping, ejection and surface powder cleaning of rheumatism and bone pain tablets is realized, which effectively solves the problem of floating powder residue after molding in traditional devices, ensures drug quality, extends shelf life, and improves production efficiency and benefits.

[0027] It is worth mentioning that the cleaning device 7 includes a manifold 71, with multiple suction nozzles 72 embedded on the lower surface of the manifold 71. The bottom of both ends of the manifold 71 is fixed to the sliding module, and both ends are connected to a connecting pipe 73. One end of the connecting pipe 73 passes through the workbench 2 and is connected to a collection mechanism 74. The two ends of the back of the collection mechanism 74 are connected to a suction fan 75 through a conduit 76. First, the suction fan 75 creates a negative pressure inside the collection mechanism 74 through the conduit 76. Under the action of the negative pressure, the suction nozzles 72 on the lower surface of the manifold 71 adsorb the floating powder on the surface of the rheumatism and bone pain tablets. The floating powder enters the collection mechanism 74 through the connecting pipe 73. The connecting pipe 73 is made of flexible hose, which can be easily adjusted to follow the position of the manifold 71. At the same time, the sliding module 6 drives the manifold 71 to move, realizing the cleaning of floating powder on the surface of the tablets in different positions. The negative pressure adsorption method of cleaning floating powder is efficient and clean, and can effectively remove floating powder on the surface of the tablets that can easily cause the medicine to deteriorate. Moreover, the setting of the sliding module 6 expands the cleaning range and improves the cleaning efficiency and effect.

[0028] The collection mechanism 74 includes a collection box 741 and a protective cover 742. A positioning component 743, which works in conjunction with the collection box 741, is provided on the outer side of the protective cover 742. An adsorption net 744, which adsorbs floating powder, is fixedly connected at equal intervals on the inner side of the protective cover 742. One end of the connecting pipe 73, away from the manifold 71, is connected to the front end of the collection box 741. One end of the duct 76 on the suction fan 75 is connected to the rear end of the collection box 741. The negative pressure generated by the suction fan 75 causes the floating powder to enter the collection box 741 through the connecting pipe 73. The adsorption net 744 intercepts and adsorbs the floating powder entering the collection box 741, facilitating the cleaning of the floating powder and reducing damage to the suction fan 75. Then, the protective cover 742 is fixed to the collection box 741 by the positioning component 743, which can be easily opened to clean the floating powder inside the collection box 741. This allows the adsorption net 744 to improve the floating powder collection efficiency, prevent the floating powder from escaping, and ensure the cleanliness of the working environment. At the same time, the detachable connection between the protective cover 742 and the collection box 741 facilitates the cleaning of the floating powder inside the collection box 741.

[0029] The positioning component 743 includes a first fixing block 7431 and a second fixing block 7432. The first fixing block 7431 is fixed at both ends of the collection box 741. A connecting post 7433 is fixedly connected to the surface of the first fixing block 7431. A positioning block 7434 that engages with the surface of the protective cover 742 is movably connected to the surface of the connecting post 7433 via a movable part. The second fixing block 7432 is fixed at both ends of the collection box 741. A limiting post 7435 is fixedly connected at a symmetrical position on the surface of the second fixing block 7432. A limiting hole 7436 is formed on the protective cover 742 at a position corresponding to the limiting post 7435. The upper end of the limiting post 7435... The connecting post 7433 on the fixing block 7431 extends upward through the limiting hole 7436 and is connected to the positioning block 7434 via a movable part. When the protective cover 742 is placed on the collection box 741, the limiting post 7435 is pre-inserted into the limiting hole 7436 of the protective cover 742, and then the positioning block 7434 is rotated to lock onto the surface of the protective cover 742, thereby fixing the protective cover 742 to the collection box 741. The positioning component 743 has a simple structure and is easy to operate. It can quickly achieve a stable connection and disassembly between the protective cover 742 and the collection box 741, which is convenient for maintenance and cleaning of the collection mechanism 74 and improves the ease of use of the equipment.

[0030] The material guiding mechanism 4 includes a sliding module 2 41, which is installed on both sides of the mounting frame 1. A connecting rod 42 is fixedly connected to the sliding module 2 41. A material guiding cylinder 43 is installed on the connecting rod 42 at a position corresponding to the mold cavity in the lower mold 33. A control valve 44 is installed at the lower end of the material guiding cylinder 43. First, the sliding module 2 41 drives the connecting rod 42 and the material guiding cylinder 43 installed on the connecting rod 42 to move. The material guiding cylinder 43 is transparent, and the inner wall of the material guiding cylinder 43 is coated with polytetrafluoroethylene (PTFE) to facilitate the rapid falling of powder raw materials. PTFE has extremely low surface energy and a very low surface friction coefficient. When the powder raw materials come into contact with the PTFE-coated material... When the coated guide cylinder 43 contacts the inner wall of the mold cavity, the friction between the raw material particles and between the raw material and the inner wall is greatly reduced, allowing it to fall more smoothly and quickly under the action of gravity. When the guide cylinder 43 is aligned with the mold cavity of the lower mold 33, the control valve 44 at the lower end of the guide cylinder 43 is opened, which can quickly transport the powdered raw material into the mold cavity, improving the filling accuracy of the raw material. Subsequently, the control valve 44 is adjusted by the controller to make it easy to control the amount of raw material conveyed, ensuring the stability of the molding quality of the rheumatism and bone pain tablets.

[0031] The ejector assembly 5 includes a pusher cylinder 51, which is installed in the inner cavity of the worktable 2. The piston rod of the pusher cylinder 51 is fixedly connected to a lifting plate 52. Ejector rods 53 are arranged in an array on the lifting plate 52. The ejector rods 53 pass through the worktable 2 and are movably connected to the cavity of the lower mold 33. Rubber pads 54 are provided around the edges of the lifting plate 52 and fit against the top of the inner cavity of the worktable 2. The pusher cylinder 51 is installed in the inner cavity of the worktable 2. The piston rod pushes the lifting plate 52 to rise. The ejector rods 53 on the lifting plate 52 eject the rheumatism and bone pain tablets formed in the cavity of the lower mold 33. The rubber pads 54 around the lifting plate 52 fit against the top of the inner cavity of the worktable 2. The rubber pads 54 can reduce vibration and noise during the ejection process, protect the equipment, and extend the service life of the equipment.

[0032] In practical use, firstly, the sliding module 41 is activated, driving the connecting rod 42 and the guide cylinder 43 to move, aligning the guide cylinder 43 with the cavity of the lower mold 33. The polytetrafluoroethylene coating on the inner wall of the guide cylinder 43 reduces the friction of the raw material. The lower control valve 44 is opened, and the powdered raw material quickly falls into the mold cavity. Next, the hydraulic cylinder 31 at the top of the mounting frame 1 is activated, and the piston rod pushes the upper mold 32 downward, cooperating with the lower mold 33 to apply pressure to the raw material and press it into the rheumatism and bone pain tablets. After molding, the pusher cylinder 51 in the inner cavity of the worktable 2 is activated, and the piston rod pushes the lifting plate 52 upward. The push rod 53 pushes the tablet out of the lower mold 33. The rubber pads around the lifting plate 52... 54. To reduce vibration and protect equipment, the sliding modules 6 on both sides of the workbench 2 drive the cleaning device 7 to move. The suction fan 75 creates negative pressure in the collection mechanism 74. The suction nozzle 72 under the manifold 71 adsorbs the floating powder on the surface of the tablets and sends it into the collection box 741 through the connecting pipe 73. The adsorption net 744 inside the box intercepts the floating powder. When the collection box 741 needs to be cleaned, the positioning block 7434 is rotated to release the protective cover 742 from the collection box 741, making cleaning convenient. The whole process realizes the integrated operation from raw material feeding, pressing and molding, ejection to floating powder cleaning, which effectively solves the problem of floating powder residue in traditional equipment and ensures drug quality and production efficiency.
