Description

Technical Field

[0001] This utility model relates to the field of tablet manufacturing technology, and in particular to a forming device for tablet manufacturing. Background Technology

[0002] Existing tablet presses for forming pharmaceutical tablets mostly involve the upper mold moving and the lower mold fitting together to compress the powder during the powder forming operation. After forming, the residual powder in the lower mold is not easy to remove, and the compression effect can only be adjusted by adjusting the hydraulic cylinder.

[0003] A search revealed that prior art CN217834849U discloses a tablet compression molding device for tablet production, including a powder upper platform unit and a shaping frame unit fixedly installed on the upper end face of the powder upper platform unit. An insertion slot plate is connected to a powder placement slot at the upper end of the powder upper column, and a push plate is movably inserted into the slot of the insertion slot plate. When there is residual powder in the powder placement slot at the upper end of the powder upper column, the push plate pushes the residual powder out through a push port opened on one side of the powder placement slot, facilitating the removal of residual powder. The distance between the shaping module and the powder placement slot can be adjusted by rotating a screw as needed. With a fixed travel distance at the extension end of the hydraulic cylinder, the closer the distance between the shaping module and the powder placement slot, the better the extrusion pressure on the powder, and the easier it is to adjust the distance between the shaping module and the powder placement slot according to the tablet forming thickness.

[0004] However, the above-mentioned device has the following problems when used: Although the above-mentioned device can process tablets of different thicknesses, in reality most tablets are circular and their diameters are not consistent. The above-mentioned device can only process tablets of a single diameter, which is not very practical. Utility Model Content

[0005] The purpose of this invention is to provide a forming device for tablet production, which aims to solve the problem that existing devices can only process tablets of a single diameter and have poor practicality.

[0006] To achieve the above objectives, this utility model provides a forming device for tablet production, including a base, a frame mounted on the base, and auxiliary components;

[0007] The auxiliary components include a hydraulic cylinder, a movable plate, a lower mold, a T-block, a limiting plate, an adjusting screw, an upper mold, an adjusting bracket, a guide component, and a stabilizing component. The hydraulic cylinder is installed at the bottom of the frame. The movable plate is connected to the output end of the hydraulic cylinder. The T-block is integrally and symmetrically arranged at the bottom of the lower mold. The T-block slides with a non-penetrating T-slot on the movable plate. The limiting plate is detachably connected to the movable plate and abuts against the T-block. The adjusting screw is threadedly connected to the adjusting bracket and passes through the adjusting bracket. The adjusting bracket is fixed to the frame. The upper mold is installed on the bottom end of the adjusting screw through a connector and slides with the lower mold. The guide component is arranged on both sides of the movable plate, and the stabilizing component is arranged on both sides of the adjusting bracket.

[0008] The auxiliary component also includes a limiting block, which is placed in the stepped groove of the moving plate and contacts the bottom plane of the lower mold.

[0009] The guide component includes a guide rod and a linear sliding bearing, the linear sliding bearing being mounted on the frame; the guide rod is integrally formed with the moving plate and is slidably connected to the linear sliding bearing.

[0010] The stabilizing component includes a left support and a right support. The left support is detachably connected to the frame and the adjusting bracket, respectively, and is symmetrically arranged and located on the left side of the adjusting bracket. The right support is detachably connected to the frame and the adjusting bracket, respectively, and is symmetrically arranged and located on the right side of the adjusting bracket.

[0011] The tablet manufacturing forming device further includes a mating component, which includes a linear guide slider module and a U-shaped block. The linear guide slider module is mounted on the adjusting bracket and arranged symmetrically. The U-shaped block is connected to the moving plate and the linear slider of the linear guide slider module by bolts.

[0012] This utility model discloses a forming device for tablet production. During processing, tablet powder is first placed into the forming cavity of the lower mold. Then, the hydraulic cylinder is controlled to extend, and after the hydraulic cylinder is activated, it pushes the moving plate to move vertically upward, thereby causing the lower mold to cooperate with the upper mold to complete the extrusion forming process of the medicine. Then, when it is necessary to process tablets of different diameters, the lower mold can be removed by removing the fixing bolts of the limiting plate, and the lower mold with a different forming cavity size can be replaced. Similarly, the upper mold with a different shape and size that slides to match the forming cavity of the lower mold can be replaced by removing the connecting parts. This application can realize the processing of tablets of different diameters and thicknesses by replacing the lower mold and upper mold with different mating dimensions, thereby solving the problem that the existing device can only process tablets of a single diameter and has poor practicality.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the forming device used in tablet production. Figure 2 This is a structural diagram of the movable plate. Figure 3This is a schematic diagram of the lower mold structure. This utility model provides a forming device for tablet production: it includes a base 101, a frame 102, and auxiliary components. The auxiliary components include a hydraulic cylinder 103, a moving plate 104, a lower mold 105, a T-block 106, a limiting plate 107, an adjusting screw 108, an upper mold 109, an adjusting bracket 110, a limiting circular block 112, a guiding component, and a stabilizing component. The guiding component includes a guide rod 113 and a linear sliding bearing 114. The stabilizing component includes a left support 115 and a right support 116. This solution solves the problem that existing devices can only process tablets of a single diameter, resulting in poor practicality. It is understood that the aforementioned solution can process tablets of different diameters and thicknesses.

[0022] In this embodiment, a frame 102 is installed above the base 101. The frame 102 is fixed by positioning pins and bolts. The hydraulic cylinder 103 is supplied with oil by an external complete hydraulic station. The complete hydraulic station is a product that directly matches the oil tank, solenoid valve group, motor, oil pump and distribution box. It can be directly purchased in the prior art. The manual control panel of the distribution box is located on the left side of the frame 102. In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve the improvement of software and methods.

[0023] The hydraulic cylinder 103 is installed at the bottom of the frame 102. The moving plate 104 is connected to the output end of the hydraulic cylinder 103. The lower mold 105 has T-shaped blocks 106 integrally and symmetrically arranged at its bottom. The T-shaped blocks 106 are slidably engaged with the non-penetrating T-slots on the moving plate 104. The limiting plate 107 is detachably connected to the moving plate 104 and abuts against the T-shaped blocks 106. The adjusting screw 108 is threadedly connected to the adjusting bracket 110 and passes through the adjusting bracket 110. The adjusting bracket 110 is fixed on the frame 102. The upper mold 109 is installed on the bottom end of the adjusting screw 108 through the connecting piece 111 and is slidably connected to the lower mold 105. The guide members are arranged on both sides of the moving plate 104, and the stabilizing members are arranged on both sides of the adjusting bracket 110. The front end cap of the hydraulic cylinder 103 is connected and fixed to the frame 102 by countersunk bolts arranged from top to bottom. The hydraulic cylinder 103 is connected to the interface of the solenoid valve group of the hydraulic station through a high-pressure oil pipe. The moving plate 104 is provided with a non-penetrating stepped cavity, and the bottom of the stepped cavity is provided with annular countersunk through holes at uniform intervals, so that the moving plate 104 can be connected to the output end of the hydraulic cylinder 103 by countersunk bolts. The moving plate 104 is provided with a non-penetrating T-shaped groove from the front to the rear, so as to facilitate the installation and positioning of the T-shaped block 106. The positioning plate 107 is fixed by bolts to position the T-shaped block 106, thereby fixing the lower mold 105 on the moving plate 104 and facilitating subsequent disassembly. The lower mold 105 is provided with a molding cavity for storing the tablet powder. When the hydraulic cylinder 103 moves vertically upward, the speed will not be too fast to avoid the powder from scattering. The adjusting bracket 110 is fixed by a positioning pin and bolt arranged from bottom to top, and is provided with a through threaded hole to cooperate with the adjusting screw 108. The indirect force exerted by the hydraulic cylinder 103 on the adjusting screw 108 when it lifts upward will not damage the threaded structure on the adjusting screw 108 and the adjusting bracket 110. The connecting piece 111 uses a T-bolt and nut for mounting the upper mold 109 at the bottom of the adjusting screw 108. The core thickness at the bottom of the upper mold 109 is greater than the depth of the forming cavity of the lower mold 105, and the core slides into the forming cavity. The guide member cooperates with the hydraulic cylinder 103 to improve the stability of the moving plate 104. The stabilizing member is used to improve the stability of the adjusting bracket 110. Since the extension length of the hydraulic cylinder 103 is fixed, the distance between the upper mold 109 and the lower mold 105 can be adjusted by rotating the adjusting screw 108, thus enabling the processing of tablets of different thicknesses.

[0024] Secondly, the limiting block 112 is placed in the stepped groove of the moving plate 104 and contacts the bottom plane of the lower mold 105. The limiting block 112 cooperates with the lower mold 105 to prevent the fixing bolts of the moving plate 104 from loosening.

[0025] Then, the linear sliding bearing 114 is mounted on the frame 102; the guide rod 113 is integrally formed with the moving plate 104 and slidably connected to the linear sliding bearing 114. The linear sliding bearing 114 has a T-shaped structure, model LMF16 LUU, and its round flange is fixed to the frame 102 by countersunk bolts. The guide rod 113 slides with the linear sliding bearing 114 to provide guidance.

[0026] Finally, the left support 115 is detachably connected to both the frame 102 and the adjusting bracket 110, and is symmetrically arranged, located on the left side of the adjusting bracket 110; the right support 116 is detachably connected to both the frame 102 and the adjusting bracket 110, and is symmetrically arranged, located on the right side of the adjusting bracket 110. The left support 115 and the right support 116 have the same dimensions and structure, and are fixed at both ends with bolts. The left support 115 and the right support 116 are used to improve the stability of the adjusting bracket 110 after installation.

[0027] When using this invention to address the problem that existing devices can only process tablets of a single diameter and have poor practicality, the process involves first placing the tablet powder into the forming cavity of the lower mold 105. Then, the hydraulic cylinder 103 is extended, pushing the moving plate 104 vertically upwards. This causes the lower mold 105 to engage with the upper mold 109, completing the extrusion molding of the medicine. Furthermore, when processing tablets of different diameters is required, the lower mold 105 can be removed by unscrewing the fixing bolts of the limiting plate 107, allowing for the replacement of lower molds with different forming cavity sizes. Similarly, by removing the connector 111, the upper mold 109 with different external dimensions that slides and matches the forming cavity of the lower mold 105 can be replaced. By replacing the lower mold 105 and the upper mold 109 with different mating dimensions, this application can realize the processing of tablets with different diameters and thicknesses. In practice, the lower mold 105 is only different in the forming cavity size, while the other dimensions are the same, and the upper mold 109 is only different in the core diameter, while the other dimensions are the same, thus ensuring good interchangeability. This solves the problem that the existing device can only process tablets with a single diameter and has poor practicality.

[0028] Example 2:

[0029] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of a tablet manufacturing molding device. Based on the first embodiment, this utility model provides a tablet manufacturing molding device, which further includes a mating component, including a linear guide slider module 201 and a U-shaped block 202.

[0030] The linear guide slider module 201 is mounted on the adjusting bracket 110 and arranged symmetrically. The U-shaped blocks 202 are connected to the moving plate 104 and the linear slider of the linear guide slider module 201 by bolts. The linear guide slider module 201 uses a THK SSR15 XW square four-hole guide slider, and its linear guide is fixed by countersunk bolts, allowing the linear slider to slide vertically on the linear guide. Through holes are provided on both side walls of the U-shaped blocks 202 to facilitate connection with the moving plate 104 and the linear slider by bolts.

[0031] In this embodiment, by setting the linear guide slider module 201 and the U-shaped block 202, a guiding mechanism can be further added when the moving plate 104 moves vertically, thereby improving the stability of the moving plate 104.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
