Description

Technical Field

[0001] This invention belongs to the field of rotary tablet press technology, and particularly relates to a tablet press with rotary demolding to prevent residual material mixing. Background Technology

[0002] Due to advancements in medical science and shifts in medical models, the focus has shifted from the traditional biomedical model to a biopsychosocial model. In the treatment process, medication is inevitably required, and the most common form of medication is tablets. Since medications are generally manufactured in tablet form, rotary tablet presses are used. When applied to medications, rotary tablet presses primarily compress drug powder into tablets. Demolding is typically achieved using a release rod, which pushes the drug powder upwards to release it, thus automating the rapid tableting process.

[0003] However, existing technologies have some problems: during the upward demolding process of a rotary tablet press with a demolding rod, powder easily falls off around the bottom edge of the formed tablet. This powder easily remains in the mold, making it easy to mix with other materials later, thus affecting the quality of subsequent forming. At the same time, after being tableted, the powder easily clumps in the mold during the pressing process and tends to stick tightly to the mold under the downward pressure of the tableting mechanism, increasing the difficulty of cleaning and making it easier to mix with subsequent processed materials. Furthermore, these clumps of powder cannot be easily collected, and during the cleaning process, they easily contaminate the materials, making them unable to be effectively recycled, thus causing resource waste and increasing costs. Therefore, we propose a tablet press with rotary demolding to prevent residual material mixing. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a tablet press with a rotary demolding mechanism that prevents residual material mixing. An anti-mixing component is mounted on the demolding rod, and this component, in conjunction with a rotating table, rotates as the demolding rod is raised and lowered. This removes powder lumps and powder adhering to the inside of the molding tank, preventing them from remaining there for extended periods. Simultaneously, the removed powder and lumps can be collected by a material collection auxiliary component for centralized collection, facilitating subsequent recycling.

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0021] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0022] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0023] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0024] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 6As shown in the figure, an embodiment of the present invention provides a tablet press with a rotary demolding mechanism to prevent residual material mixing, comprising: a tablet press, which is composed of a worktable 1, a demolding mechanism 2, a filling mechanism 3, a rotary table 4, and a discharge plate 7. The upper surface of the rotary table 4 has multiple sets of molding grooves 11, which are arranged in a ring at equal intervals; demolding rods 9, which are provided in multiple sets and are paired with the molding grooves 11, and are elastically connected to the inside of the molding grooves 11; and an anti-mixing component 6, which consists of a driving component. The equipment includes a material removal component, which has the same number of sets as the demolding rod 9, and the material removal component and the demolding rod 9 are arranged in pairs. The material removal component is correspondingly located inside the molding groove 11. The demolding rod 9 is rotatably connected to the rotary table 4 through the material removal component and the driving component. The material collection component 5 is arranged around the rotary table 4. The material collection auxiliary component 8 is arranged inside the rotary table 4 and is connected to the material collection component 5. The demolding rod 9 is correspondingly located at the connection between the material collection auxiliary component 8 and the material collection component 5.

[0026] By designing the demolding rod 9 to connect with the material collection auxiliary component 8 and the material collection component 5, when the adjusting rod 901 and the demolding top plate 902 are matched with the demolding mechanism 2 to demold the material, the powder and lumps generated will remain at the connection between the material collection auxiliary component 8 and the material collection component 5. Then, with the help of the power fan 801, the wind force generated by the power fan 801 can blow the remaining powder and lumps into the material collection shell 501 for collection, making it convenient to concentrate the material and facilitate recycling.

[0027] Furthermore, the demolding rod 9 is composed of an adjusting rod 901 and a demolding top plate 902. The lower end of the forming groove 11 is provided with a through hole corresponding to the adjusting rod 901, and the demolding rod 9 is elastically connected to the rotary table 4. The demolding top plate 902 is located at the upper end of the adjusting rod 901. By setting the demolding top plate 902 and the upper end of the adjusting rod 901, the size of the adjusting rod 901 is matched with that of the forming groove 11, and the demolding top plate 902 can easily cooperate with the adjusting rod 901 to push upwards, so as to demold the pressed finished product.

[0028] Furthermore, the material removal component includes a material removal block 604 and a gear 602. Multiple sets of material removal blocks 604 are provided, and the multiple sets of material removal blocks 604 are equidistantly arranged around the bottom of the demolding top plate 902. The side wall of the adjusting rod 901 is provided with multiple sets of tooth grooves 603 corresponding to the gear 602, and the multiple sets of tooth grooves 603 are equidistantly arranged. All sets of tooth grooves 603 are meshed with the gear 602, and the gear 602 is rotatably connected to the rotary table 4. By using a design where multiple sets of material removal blocks 604 are equidistantly arranged around the bottom periphery of the demolding top plate 902, and the material removal blocks 604 can be made of rubber to easily adhere to the inner wall of the molding groove 11, the powder and lumps attached to the inner wall of the molding groove 11 can be easily scraped off during the descent of the demolding top plate 902, thus avoiding the occurrence of residue and effectively preventing the impact on the quality of subsequent material processing.

[0029] Furthermore, the multiple sets of material removal blocks 604 are inclined on the side near the bottom center of the demolding top plate 902, and the outer side of the multiple sets of material removal blocks 604 is attached to the inner wall of the molding groove 11. By tilting the material removal block 604 near the bottom center of the demolding top plate 902, when the material removal block 604 descends and rotates through the cooperation between the gear 602 and the annular toothed plate 601, the tilted position can better scrape off the highly adhesive powder blocks and powder, thereby improving the cleanliness inside the molding groove 11. The tilted angle also facilitates the extrusion and cutting of powder blocks accelerated during the downward pressing process into smaller pieces, making it easier for the power fan 801 to blow them.

[0030] Furthermore, a connecting hole is provided on one side of the multiple sets of through holes, and multiple sets of expansion plates 13 are fixedly installed on the side wall of the rotary table 4 near the connecting hole. The expansion plates 13 are paired with the connecting holes. The gear 602 is rotatably connected to the expansion plate 13. A ring toothed plate 601 is meshed on one side of the gear 602, and the ring toothed plate 601 is fixedly connected to the discharge plate 7. The ring toothed plate 601 is correspondingly arranged above the demolding mechanism 2. With the design of a ring toothed plate 601 meshing with one side of the gear 602, when the rotary table 4 rotates, the position of the discharge plate 7 is fixed, which in turn fixes the position of the ring toothed plate 601. When the gear 602 driven by the rotary table 4 rotates, it can cooperate with the ring toothed plate 601 to rotate, which in turn cooperates with the tooth groove 603 to drive the adjusting rod 901 to rotate. The adjusting rod 901 can then drive the demolding top plate 902 to rotate, thereby achieving the rotation of the top plate to demold the material of the pressed finished product. This can minimize the occurrence of excessive powder lumps and powder demolding around the bottom of the pressed finished product. like Figure 2 As shown, the length of the annular toothed plate 601 in this case extends from above the demolding mechanism 2 to the rear side of the upper surface of the worktable 1. Therefore, when the demolding rod 9 is away from the demolding mechanism 2, it can still rotate, which makes it convenient for multiple sets of material removal blocks 604 to descend and rotate, thereby facilitating the thorough cleaning of powder blocks and powder with strong adhesion inside the molding tank 11.

[0031] Furthermore, the material collection assembly 5 includes a material collection shell 501, which is provided with multiple groups of partition plates 502 inside. The multiple groups of partition plates 502 are arranged in a ring at equal intervals, and the material collection shell 501 is divided into multiple groups of material collection troughs through the multiple groups of partition plates 502. The design of the material collection shell 501, which is divided into multiple sets of material collection tanks by a multi-group partition plate 502, allows each material collection tank to be connected to a through hole, so that it can be used in conjunction with the power fan 801 to collect powder and powder lumps in different material collection tanks, thereby facilitating subsequent recycling.

[0032] Furthermore, a through hole communicating with the material collection tank is provided at the lower end of one side of the multi-component molding tank 11. The side wall of the rotary table 4 is provided with multiple anti-backflow shells 503 communicating with the through holes. A feed hole is provided on one side of the anti-backflow shell 503, and the inside of the feed hole gradually narrows from one end close to the molding tank 11 to the other end. The feed hole is designed to gradually narrow from one end near the forming groove 11 to the other end. The feed hole is trapezoidal, and the material enters the collection groove from the wide end to the narrow end. The material is not allowed to enter from the narrow end, which makes it easy to restrict the material and effectively prevents the material from flowing back due to the wind force generated by the power fan 801.

[0033] Furthermore, the material collection auxiliary component 8 includes a power fan 801. The lower end of the rotary table 4 is provided with an installation groove, and the power fan 801 is located in the lower end of the installation groove. The upper end of the installation groove is provided with a guide plate 802, and the upper end of the inner wall of the installation groove is provided with multiple sets of push holes 12 that communicate with the forming groove 11. Multiple sets of guide grooves are provided around the bottom of the guide plate 802, and the interior of the multiple sets of guide grooves is inclined from one end near the center of the bottom of the guide plate 802 to the other end. With multiple sets of guide channels, one end of the guide plate 802 is inclined near the bottom center, and the other end is set at an angle. When the wind generated by the power fan 801 blows the guide plate 802 to the bottom center, it can be divided by multiple guide channels. Following the inclined angle, it enters the push hole 12 to blow the powder and powder blocks scraped by the descraping block 604 and blow them into the collection shell 501, thereby facilitating uniform distribution and separation, and achieving a better concentration of powder and powder blocks.

[0034] Furthermore, a feeding assembly 10 is correspondingly provided inside the forming groove 11, and the feeding assembly 10 is rotatably connected to the adjusting rod 901 via a power fan 801; According to the design of the feeding assembly 10, which is rotatably connected to the adjusting rod 901 via the power fan 801, the feeding assembly 10 consists of feeding blades 101 and mounting ring 102. Multiple sets of feeding blades 101 are provided, and these multiple sets of feeding blades 101 are arranged in a ring at equal intervals outside the mounting ring 102. The through hole opened at the lower end of the forming groove 11, such as... Figure 4 As shown, the lower periphery of the forming groove 11 is connected to the push hole 12 and the through hole in the central position. Thus, the lower periphery of the forming groove 11 is connected to the push hole 12 and the through hole, forming a through shell with the through hole as the center. The mounting ring 102 is rotatably mounted on the side wall of the through shell, and the multiple sets of feeding blades 101 are inclined to facilitate the airflow generated by the power fan 801 and rotate. This facilitates the rotation of the mounting ring 102 as the base to push away the powder block shoveled off by the removed material block 604, making it easier to centrally process the powder block. Specifically, the side of the multiple sets of feeding blades 101 away from the mounting ring 102 is at a certain distance from the inner wall of the connection between the through hole and the push hole 12, so as to facilitate the wind force generated by the power fan 801 to blow the powder into the collection shell 501 for collection.

[0035] Working principle and usage process of this invention: The rotary table 4 and the filling mechanism 3 are started to perform tableting. The demolding rod 9 driven by the rotary table 4, together with the demolding mechanism 2, pushes upward to demold the material. When the material is demolded, the gear 602 will work with the ring tooth plate 601 to drive the adjusting rod 901 to rotate. When the adjusting rod 901 rotates, it will control the demolding top plate 902 to rotate, which will then drive the multiple sets of material removal blocks 604 to rotate, lift and rotate, and remove the attached powder blocks and powder. Then, the power fan 801 is started to blow the removed powder blocks and powder into the collection shell 501 for collection.
