Description

Technical Field

[0001] This application relates to the field of tablet packaging technology, and more particularly to a tablet packaging machine. Background Technology

[0002] As one of the most common drug dosage forms, the packaging quality of tablets (including tablets, capsules, pills, and other solid oral preparations) directly affects the safety, efficacy, and ease of use of drugs. Automated tablet packaging machines play a crucial role in the pharmaceutical industry, used to quantitatively dispense, count, and seal bulk tablets into packaging materials such as blister packs (bubble-eye packaging) or sachets (strip packaging).

[0003] However, existing tablet packaging machines have the following drawbacks: for example, they cannot fill the gas inside the blister pack, and some important medicines (or tablets that require a longer shelf life) cannot be packaged. Therefore, this utility model provides a new type of tablet packaging machine. Utility Model Content

[0004] The purpose of this application is to provide a tablet packaging machine that can pre-package tablets to facilitate subsequent filling with protective gas and then resealing.

[0005] To achieve the above objectives, this application provides a tablet packaging machine, which includes a worktable, a guide table, an edge heat sealing assembly, a mounting plate assembly, a bracket, a roller mounting component, a cap film roll, and a filler film roll.

[0006] A guide platform is fixedly installed on the top of the workbench. Mounting plate assemblies are fixedly installed on the top of the workbench and on both sides of the guide platform. An edge heat sealing assembly is installed between the two sets of mounting plate assemblies. A bracket is set at the front end of the guide platform. A roller mounting component is fixedly installed on the bracket. A cover film roll and a filler film roll are rotatably mounted on the roller mounting component. When packaging tablets, the filler film roll is placed between the cover film roll and the bottom sheet, and the edge heat sealing assembly is used to heat seal the edge. The semi-finished tablet packaging material formed in this way can be filled with protective gas from the end. After filling with protective gas, a second heat sealing is performed. This process facilitates subsequent filling with protective gas and secondary sealing to obtain the final tablet packaging.

[0007] Further preferably, the edge heat sealing assembly includes: a heat sealing roller rotatably mounted between the two sets of mounting plates, a heating assembly, and a servo motor.

[0008] The heat-sealing roller has at least two solid flanges on its outer side. The two solid flanges can heat-seal two edges. If there are more than two solid flanges, multiple channels are formed. For example, three solid flanges form two channels, four solid flanges form three channels, etc. The heating component is fixedly installed on the top of the mounting plate assembly. The heating component is used to heat the solid flanges so that the temperature of the solid flanges meets the hot air requirements. The servo motor is fixedly installed on the outer side of the mounting plate assembly. The output end of the servo motor is connected to the heat-sealing roller drive. The servo motor is used to drive the heat-sealing roller to rotate. The rolling solid flanges squeeze and heat-seal the packaging layer.

[0009] Further preferably, the heat-sealing roller includes a first roller body and a second roller body that are symmetrically distributed, and the first roller body and the second roller body are fastened and fixedly installed. This design facilitates the installation of the heating component.

[0010] The second roller body includes: a connecting column, a solid flange fixedly installed on the outer side of the connecting column, and an annular opening on the side of the solid flange, the annular opening corresponding to the heating component.

[0011] More preferably, the heating assembly includes a crossbeam fixedly mounted on the top of the mounting plate assembly, an arc-shaped heating element, and two annular heat conductors.

[0012] An arc-shaped frame is fixedly connected to the side of the crossbar, and an arc-shaped heating element is fixedly installed on the inner side of the arc-shaped frame. Both ends of the arc-shaped heating element are fixedly connected to an annular heat conductor, which is located inside the annular opening, thus enabling sufficient heating of the solid flange.

[0013] Further preferably, the arc-shaped heating element includes an arc-shaped covering body, and a plurality of heating columns are fixedly arranged on the inner side of the covering body. The arc-shaped heating element is arranged above the heat-sealing roller, so it will not affect the material below and avoid the material from softening due to heat.

[0014] A further preferred embodiment includes an auxiliary drive assembly disposed on one side of the edge heat-sealing assembly, the auxiliary drive assembly being used to keep the packaged product moving smoothly forward.

[0015] The auxiliary drive assembly includes: a sub-plate fixedly connected to the side of the mounting plate assembly, a roller shaft rotatably mounted on the side of the sub-plate, a flexible sleeve fixedly mounted on the outer side of the roller shaft, and a first motor fixedly mounted on the other side of the sub-plate, the first motor being drively connected to the roller shaft.

[0016] Further preferably, the guide platform includes: a main board body, at least two sets of strips are fixedly connected to the top of the main board body, and a bubble guide gap is formed between two adjacent sets of strips, so as to guide the bottom sheet.

[0017] Preferably, the bottom of the bracket is fixedly connected to the ground or workbench to maintain a stable distance between the bracket and the workbench.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] (1) By designing edge heat sealing components, roller mounting components, cover film rolls and filler film rolls, when packaging tablets, the filler film rolls are placed between the cover film rolls and the bottom sheet, and the edge heat sealing components are used to heat seal the edges. The resulting tablet packaging semi-finished material can be filled with protective gas from the end. After filling with protective gas, a second heat sealing is performed. This process facilitates subsequent filling with protective gas and then secondary encapsulation to obtain the final tablet packaging. Attached Figure Description

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figures 1-5 The tablet packaging machine shown is used for pre-packaging tablets to facilitate subsequent filling with protective gas and secondary sealing to obtain the final tablet packaging. Specifically, it includes a worktable 1, a guide table 2, an edge heat sealing assembly, a mounting plate assembly 3, a bracket 6, a roller mounting component 7, a cover film roll 8, and a filler film roll 9.

[0031] A guide platform 2 is fixedly installed on the top of the workbench 1. The guide platform 2 is used to guide the bottom sheet 5. The bottom sheet 5 is output from the blister forming equipment and has a strip-shaped structure (the bottom sheet 5 has blister packs for holding tablets, and the tablet dispensing device fills each blister pack opening with tablets). Mounting plate assemblies 3 are fixedly installed on the top of the workbench 1 and on both sides of the guide platform 2. An edge heat sealing assembly is installed between the two mounting plate assemblies 3. The edge heat sealing assembly forms at least two heat sealing lines on the packaging material. A bracket 6 is set at the front end of the guide platform 2. A roller mounting component 7 is fixedly installed on the bracket 6. A cover film roll 8 and a filler film roll 9 are rotatably mounted on the roller mounting component 7. When packaging tablets, the filler film roll 9 is placed between the cover film roll 8 and the bottom sheet 5, and the edge heat sealing assembly is used to heat seal the edges. The semi-finished tablet packaging material formed in this way can be filled with protective gas from the end. After filling with protective gas, a second heat sealing is performed. This process facilitates subsequent filling with protective gas and secondary sealing to obtain the final tablet packaging.

[0032] In the subsequent stages of the tablet packaging machine, the continuous pre-packaged products are cut into 50-80cm segments. One end of the segmented pre-packaged product is placed in the protective gas chamber, and the other end is placed in the negative pressure chamber. In this way, the protective gas passes through the segmented pre-packaged products, expelling the air in the blister packs and filling them with protective gas. Finally, a second heat seal is performed to make each blister pack opening independent. The resulting tablet packaging can extend the shelf life of the tablets.

[0033] In one embodiment, the edge heat sealing assembly includes: a heat sealing roller 10 rotatably mounted between two sets of mounting plates 3, a heating assembly 12, and a servo motor 11.

[0034] At least two solid flanges 1022 are provided on the outer side of the heat sealing roller 10. The outer side of the solid flanges 1022 is provided with knurling. The two solid flanges 1022 can heat seal two edges. If there are more than two solid flanges 1022, multiple channels are formed. For example, three solid flanges 1022 form two channels, four solid flanges 1022 form three channels, etc. The heating component 12 is fixedly installed on the top of the mounting plate group 3. The heating component 12 is used to heat the solid flanges 1022 so that the temperature of the solid flanges 1022 meets the hot air requirements. The servo motor 11 is fixedly installed on the outer side of the mounting plate group 3. The output end of the servo motor 11 is connected to the heat sealing roller 10 for transmission. The servo motor 11 is used to drive the heat sealing roller 10 to rotate. The rolling solid flanges 1022 squeeze and heat seal the packaging layer.

[0035] In use, the servo motor 11 drives the heat sealing roller 10 to rotate, and the heating component 12 heats the solid flange 1022 on the heat sealing roller 10. The solid flange 1022 rolls the material to form a strip-shaped sealing line on the material.

[0036] In one embodiment, the heat-sealing roller 10 includes a first roller body 1001 and a second roller body 1020 that are symmetrically distributed. The first roller body 1001 and the second roller body 1020 are fastened and fixedly installed. This design facilitates the installation of the heating component 12, which is placed between the first roller body 1001 and the second roller body 1020. Then, the first roller body 1001 and the second roller body 1020 are aligned and fastened together.

[0037] The second roller body 1020 includes: a connecting column 1021, a solid flange 1022 fixedly installed on the outer side of the connecting column 1021, and an annular opening 1023 opened on the side of the solid flange 1022, which corresponds to the heating component 12; the first roller body 1001 and the second roller body 1020 have the same structure, and will not be described in detail here.

[0038] In one embodiment, the heating assembly 12 includes: a crossbeam 1201 fixedly mounted on the top of the mounting plate assembly 3, an arc-shaped heating element 1230, and two annular heat conductors 1231.

[0039] An arc-shaped frame 1202 is fixedly connected to the side of the cross frame 1201. Two sets of cross frames 1201 are provided, and the arc-shaped frame 1202 is fixedly installed between the two sets of cross frames 1201. An arc-shaped heating element 1230 is fixedly installed on the inner side of the arc-shaped frame 1202. Both ends of the arc-shaped heating element 1230 are fixedly connected to an annular heat conductor 1231. The annular heat conductor 1231 is located inside the annular opening 1023, so that the solid flange 1022 can be fully heated.

[0040] The arc-shaped heating element 1230 is positioned on the upper side of the heat-sealing roller 10, so that the arc-shaped heating element 1230 will not radiate heat onto the material, thus preventing the material from softening; the arc-shaped heating element 1230 heats the two solid flanges 1022 through two annular heat conductors 1231, ensuring that the two solid flanges 1022 have sufficient temperature.

[0041] The arc-shaped heating element 1230 includes an arc-shaped covering body 1204. Several heating columns 1232 are fixedly arranged on the inner side of the covering body 1204. The arc-shaped heating element 1230 is arranged above the heat sealing roller 10 and will not affect the material below, thus preventing the material from softening due to heat.

[0042] In one embodiment, an auxiliary drive component 4 is also designed and disposed on one side of the edge heat-sealing component. The auxiliary drive component 4 is used to keep the packaged product moving forward smoothly in a strip shape.

[0043] Specifically, the auxiliary drive assembly 4 includes: a sub-plate 401 fixedly connected to the side of the mounting plate assembly 3, a roller shaft 403 rotatably mounted on the side of the sub-plate 401, a flexible sleeve 404 fixedly mounted on the outer side of the roller shaft 403, and a first motor 402 fixedly mounted on the other side of the sub-plate 401, the first motor 402 being connected to the roller shaft 403 in a transmission connection.

[0044] The first motor 402 drives the roller shaft 403 to rotate, which in turn drives the soft sleeve 404 to rotate. The soft sleeve 404 is attached to the surface of the material, driving the material to move forward smoothly.

[0045] In this embodiment, the guide platform 2 includes a main board body 201, at least two sets of strips 202 are fixedly connected to the top of the main board body 201, and a blister guide gap 203 is formed between two adjacent sets of strips 202, so as to guide the bottom sheet 5, that is, the blister of the bottom sheet 5 moves inside the blister guide gap 203.

[0046] In this embodiment, the bottom of the support 6 is fixedly connected to the ground or the workbench 1 to maintain a stable distance between the support 6 and the workbench 1.
