Description

Technical Field

[0001] The invention relates to the technical field of presses, and more particularly to a tablet processing device for producing compound supplementary colon sustained-release tablets. Background Art

[0002] The main ingredients of Fufang Bupai Colon Sustained Release Tablets include aloe extract, senna extract, rhubarb extract, etc. It is a Chinese patent medicine that has the effects of moistening the intestines, softening stools, and promoting defecation. In its preparation process, it is necessary to use a tablet forming processing device to extrude the prepared drug powder into tablets, and then package the formed tablets.

[0003] At present, the conventional tablet forming processing device generally consists of an extrusion mechanism, a forming die and a feeding mechanism. When in use, the powder is loaded into the forming hole of the forming die through the feeding mechanism, and then the powder in the forming hole is squeezed by the extrusion mechanism to finally obtain a formed tablet. In this process, since the tablet formed after extrusion is in close contact with the inner wall of the forming hole, some of the formed tablets are difficult to separate from the forming hole, and often need to be manually assisted by tools to separate.

[0004] In order to solve the problem that the formed tablets are difficult to separate from the forming holes, in the prior art, such as the publication number CN209552526U, a tablet pressing and forming device is disclosed, including a base and a hollow frame fixedly connected to the base, wherein the inner walls of the hollow frame near the middle are respectively connected to the rotating shafts, and the two rotating shafts are fixedly connected to the rotating seat. The lower pressing die and the compression spring are arranged in the forming vessel, and after the tablets are extruded and formed, the elastic force of the compression spring is used to drive the lower pressing die to push the formed tablets out of the forming vessel. Although the device can realize the automatic separation between the formed tablets and the forming vessel, the elastic coefficient of the compression spring is small, and the pressure generated by the extrusion mechanism when extruding the powder is much greater than the elastic coefficient of the compression spring. After the compression spring is frequently subjected to a large pressure, it will be damaged due to metal fatigue and deformation, and finally it will not be able to provide elastic force for the lower pressing die normally. If the pushing function of the lower pressing die is to be maintained, the compression spring needs to be replaced frequently, and the frequent replacement of the compression spring is not only difficult in actual operation, but also increases the use cost of the forming processing device. Therefore, there is an urgent need for a tablet processing device for producing compound supplementary colon sustained-release tablets, which has an automatic tablet detachment function and can maintain long-term operation of the automatic detachment function.

DETAILED DESCRIPTION

[0034] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0035] Please refer to Figure 1 A tablet processing device for producing compound supplementary colon sustained-release tablets includes: an operating table 1, an extrusion mechanism 2, a molding mechanism 3 and a feeding mechanism 4, wherein the feeding mechanism 4 is used to add medicine powder to the molding mechanism 3, and the extrusion mechanism 2 is used to extrude the medicine powder filled in the molding mechanism 3.

[0036] For details, please refer to Figures 2 to 4The molding mechanism 3 includes a molding die 31, two ejection assemblies 32, a support assembly 33 and a flip drive assembly 34. The molding die 31 is rotatably mounted on the operating table 1. The top surface of the molding die 31 is provided with two rows of molding hole groups, and the molding hole groups include five molding holes 35 that are equidistantly distributed. The two ejection assemblies 32 are arranged one-to-one with the two rows of molding hole groups. The ejection assembly 32 includes a rotating rod 321, five transmission gears 322 and five movable parts 323. The rotating rod 321 is rotatably mounted in the molding die 31. The five movable parts 323 are arranged one-to-one in the five molding holes 35. The movable parts 323 include a fixed part and a movable part. The fixed part is fixed to the inner wall of the molding hole 35. The fixed part divides the molding hole 35 into two upper and lower molding areas. The movable part is slidably connected to the fixed part. The five movable parts are meshed with the five transmission gears 322 one-to-one. The support assembly 33 is used to provide support for the bottom of the molding mold 31 and limit the rotation of the molding mold 31. The flip drive assembly 34 is used to drive the support assembly 33 to separate from the molding mold 31, flip the molding mold 31 180 degrees, and rotate the rotating rod 321.

[0037] It should be noted that when the above scheme is adopted to produce the compound supplementary colon sustained-release tablets, the prepared powder is first added to the feeding mechanism 4, and the compound supplementary colon sustained-release powder is automatically and quantitatively added to each forming hole 35 of the forming die 31 by the feeding mechanism 4. Under the interception effect of the top of the movable member 323, the powder is accumulated in the forming area above the forming hole 35, and then the extrusion mechanism 2 is moved downward to extrude the powder in the forming hole 35. After the powder is squeezed, it forms a tablet in the forming hole 35, and then the extrusion mechanism 2 is moved upward to reset. At this time, the flip The rotation drive assembly 34 is synchronously driven during the upward resetting process of the extrusion mechanism 2. The flip drive assembly 34 can first drive the support assembly 33 to separate from the forming mold 31, release the restriction on the forming mold 31, and then start to drive the forming mold 31 to flip 180 degrees, so that the formed tablets are flipped toward the operating table 1. Some tablets will automatically separate from the forming hole 35 under the action of gravity, while some tablets cannot temporarily separate from the forming hole 35 due to too close contact with the forming hole 35. At this time, the flip drive assembly 34 continues to move, The rotating rod 321 is driven to rotate forwardly, so that the transmission gear 322 drives the movable part 323 to slide downward, and the tablets located in the lower forming area are ejected. After the tablets are automatically separated, the extrusion mechanism 2 reaches the initial position and stops moving. During the next processing, the extrusion mechanism 2 moves downward, and the rotating rod 321 is first driven by the flip driving assembly 34 to rotate, which can drive the movable part 323 to move and reset. Then the forming mold 31 is driven to flip 180 degrees and reset, and then the powder is added to the forming hole 35 through the feeding mechanism 4, and the above steps are repeated. The operation can realize the continuous production of the compound supplementary colon sustained-release tablets. In this way, through the coordinated transmission between the flip drive component 34 and the ejection component 32, the movable part 323 can be driven to synchronously and adaptively move in the forming hole 35, and then the formed tablets can be ejected to realize the automatic separation function of the tablets and the forming hole 35. In the process of squeezing the powder by the extrusion mechanism 2, since the top of the movable part 323 is flush with the bottom of the forming area above the forming hole 35, it will not affect the tablet molding and is not easily damaged by pressure. Therefore, it can be used for a long time without frequent replacement.

[0038] Please refer to Figures 5 and 6The movable part 323 includes a limiting ring body 3231, a sliding rod 3232 and two circular plates 3233. The limiting ring body 3231 is fixedly installed in the middle of the inner side of the forming hole 35. The top and bottom of the limiting ring body 3231 are provided with circular grooves adapted to the circular plates 3233. The sliding rod 3232 is slidably connected with the limiting ring body 3231. A first tooth groove section 3234 is provided on one side of the sliding rod 3232. The transmission gear 322 is meshed with the first tooth groove section 3234. The two circular plates 3233 are respectively fixed to the top and bottom ends of the sliding rod 3232. The limiting ring body 3231, the sliding rod 3232 and the circular plates 3233 can all be made of stainless steel with higher hardness, and the limiting ring body 3231 can be welded to the inner wall of the forming hole 35.

[0039] It should be noted that when the above-mentioned movable part 323 is in use, in its initial state, the circular plate 3233 located above is flush with the top of the limiting ring body 3231, so that the bottom of the molding area above the molding hole 35 is in a flat state. When adding powder, the powder will not flow into the molding area below the molding hole 35. When the extrusion mechanism 2 extrude the powder, since the circular plate 3233 will not be displaced, it will not affect the normal molding of the tablet. The force acting on the circular plate 3233 is evenly and vertically distributed on its top and dispersed to the molding die 31 through the limiting ring body 3231. Therefore, the circular plate 3233 is not easily damaged. When the molded tablet is ejected, the rotating rod 321 is rotated to make the transmission gear 322 drive the sliding rod 3232 to slide downward, so that the circular plate 3233 located below generates a thrust on the tablet directly below it. When the circular plate 3233 moves down to the bottom end of the molding hole 35, the tablet can be separated from the molding hole 35.

[0040] Please refer to Figure 7 The support assembly 33 includes four support plates 331. The support plates 331 are all made of reinforced steel structure and have high anti-deformation performance. The four support plates 331 are symmetrically distributed on both sides of the forming mold 31 in a group of two. One end of the support plate 331 contacts the bottom of the forming mold 31, and the other end of the support plate 331 is slidably connected to the operating table 1. A return spring 332 is fixedly installed between the support plate 331 and the operating table 1.

[0041] It should be noted that when the above-mentioned support assembly 33 is in use, the bottom of the molding die 31 contacts the top surfaces of the four support plates 331 to provide horizontal support for the molding die 31. When the molding die 31 is subjected to the pressure of the extrusion mechanism 2, the molding die 31 can be prevented from rotating, thereby maintaining the stability of the molding die 31 and ensuring that the extrusion mechanism 2 and the molding die 31 are accurately docked. When the flip drive assembly 34 drives the molding die 31 to flip, the four support plates 331 can be driven by the flip drive assembly 34 to synchronously slide and separate from the molding die 31, thereby releasing the bottom of the molding die 31. Restriction, then the flipping drive component 34 can drive the forming mold 31 to flip normally, and after the tablet is separated from the forming hole 35, after the forming mold 31 flips again, the support plate 331 contacts the bottom of the forming mold 31 again under the driving action of the flipping drive component 34, providing support for the forming mold 31. In this way, the support component 33 is used in conjunction with the flipping drive component 34 to achieve synchronous and adaptive switching of the use status of the support component 33 and the forming mold 31. There is no need for manual active regulation of the use status of the support component 33, which is more convenient to use and well matches the use of the forming mechanism 3.

[0042] Please refer to Figure 8 There are two flip drive assemblies 34 and two ejection assemblies 32, and the two flip drive assemblies 34 are symmetrically arranged on both sides of the forming mold 31. The flip drive assembly 34 includes a flip driving member, an extrusion member and a rotation driving member. The top of the flip driving member is connected to the movable end of the extrusion mechanism 2, which is used to drive the forming mold 31 to flip 180 degrees. The extrusion member is used to generate a linear extrusion force on the support plate 331, so that one end of the support plate 331 is separated from the forming mold 31, and the rotation is used to drive the rotating rod 321 to rotate.

[0043] For details, please refer to Figures 8 to 9The flip driving member includes a limiting guide rod 341 and a matching gear 342. The top of the limiting guide rod 341 is fixed to the movable end of the extrusion mechanism 2, and the outer side thereof is slidably connected to the operation table 1. One side of the limiting guide rod 341 is provided with a second tooth groove section 343 adapted to the matching gear 342. One side of the limiting guide rod 341 has two giving way grooves 344, which are respectively located above and below the second tooth groove section 343. The matching gear 342 is fixedly installed on the rotating end of the forming mold 31. The extrusion member includes a bottom plate 345, two extrusion plates 346 and two inclined grooves 347. The bottom plate 345 is fixedly installed at the bottom end of the limiting guide rod 341. The two extrusion plates 346 are respectively fixedly installed at the two ends of the bottom plate 345. The two inclined grooves 347 are opened at the bottom of the two support plates 331. The tops of the two extrusion plates 346 are respectively in sliding contact with the two inclined grooves 347. The rotating driving member includes two rotating gears 348 and two racks 349 matched with the rotating gears 348. The two rotating gears 348 are respectively fixedly connected to one end of two rotating rods 321 located on the same side, and the two racks 349 are respectively fixedly installed on the lower ends of the two extrusion plates 346.

[0044] It should be noted that when the above-mentioned flip drive assembly 34 is in use, when the extrusion mechanism 2 moves downward and approaches the forming mold 31, since the matching gear 342 is in the position of the yield groove 344 above the limiting guide rod 341, during the process of the limiting guide rod 341 moving downward with the extrusion mechanism 2, the yield groove 344 will not drive the matching gear 342 to rotate, and the limiting guide rod 341 cooperates with the operating table 1 to slide, thereby limiting the extrusion mechanism 2 so that it can be accurately docked with the forming mold 31. After the extrusion mechanism 2 completes an extrusion operation and begins to reset upward, the limiting guide rod 341 moves upward with the extrusion mechanism 2. After the extrusion mechanism 2 moves up to the initial position, the extrusion mechanism 2 continues to The limit guide rod 341, the bottom plate 345 and the extrusion plate 346 move upward together. When the extrusion plate 346 moves upward, its top generates a horizontal extrusion force on the inclined groove body 347, which can drive the support plate 331 to slide horizontally away from the forming mold 31, and the return spring 332 is squeezed by the support plate 331 and gradually shrinks. When the top of the extrusion plate 346 extends to the top of the support plate 331, the support plate 331 is completely separated from the forming mold 31. At this time, the extrusion plate 346 continues to move upward and will not continue to generate an extrusion force on the support plate 331. The second tooth groove section 343 moves upward and meshes with the matching gear 342. The limit guide rod 341 continues to move upward with the extrusion mechanism 2, which can drive the matching gear 342 The second tooth groove section 343 is separated from the matching gear 342, and the molding die 31 no longer rotates. At this time, the formed tablet originally in the molding area above the molding hole 35 is turned downward, and the extrusion mechanism 2 continues to move upward, so that the rack 349 starts to mesh with the corresponding rotating gear 348, and drives the rotating gear 348 and the rotating rod 321 to rotate together, and finally the circular plate 3233 below pushes the tablet downward to separate the tablet from the molding hole 35. After that, the extrusion mechanism 2 starts to move downward to perform the next tableting operation, so that the rack 349 is separated from the rotating gear 348, the movable member 323 is movable and reset, and the molding die 31 is turned over and reset again. The support plate 331 slides and contacts with the bottom of the forming mold 31, and the extrusion mechanism 2 docks with the forming mold 31 again; in this way, by setting the flip drive component 34, it uses the lifting action of the extrusion mechanism 2 as the power source, and is used in conjunction with the forming mold 31 to realize the automatic flipping action of the forming mold 31, and is used in conjunction with the support component 33 to realize the automatic release of the restriction on the forming mold 31, and is used in conjunction with the ejection component 32 to realize the automatic separation of the tablet from the forming hole 35. Through the coordinated transmission of the flip drive component 34 and various components, the tablet processing device can perform extrusion molding and automatic tablet separation continuous operations without human intervention in the middle, thereby ensuring the processing speed.

[0045] Please refer to Figure 8 and Fig.10The extrusion mechanism 2 includes a fixed frame 21, a cylinder 22 and an extrusion seat 23. The fixed frame 21 is fixedly installed on the top of the operating table 1, the cylinder 22 is fixedly installed on the upper end of the fixed frame 21, and the extrusion seat 23 is arranged in parallel just above the forming mold 31. The top of the extrusion seat 23 is fixedly connected to the telescopic end of the cylinder 22, and the bottom of the extrusion seat 23 is provided with extrusion shafts with the same number and size as the forming holes 35.

[0046] It should be noted that when the extrusion mechanism 2 is in use, the cylinder 22 drives the extrusion seat 23 to move downward, so that the extrusion seat 23 moves downward and docks with the molding die 31 below to complete the tablet extrusion molding operation.

[0047] Please refer to Fig.10 The feeding mechanism 4 includes a storage hopper 41, an electric push rod 42 and a feeding head 43. The storage hopper 41 is fixedly installed on the top of the operating table 1. The fixed end of the electric push rod 42 is fixedly connected to one side of the storage hopper 41. One side of the feeding head 43 is fixedly connected to the telescopic end of the electric push rod 42. The feeding end of the feeding head 43 is connected to the discharging end of the storage hopper 41 through a telescopic pipe. The telescopic pipe can be a corrugated pipe, and an electronic valve is also provided on the telescopic pipe.

[0048] It should be noted that when the above-mentioned feeding mechanism 4 is in use, the electric push rod 42 drives the feeding head 43 to move horizontally to the top of the forming mold 31, and by opening the electronic valve, the powder in the storage hopper 41 enters the feeding head 43, and then is evenly introduced into the forming hole 35 by the feeding head 43.

[0049] Please refer to Fig.10 A material guide trough 5 is provided at the top of the operating table 1 and below the forming mold 31 , and a collecting bucket 6 is provided at the bottom of the operating table 1 and below the material guide trough 5 .

[0050] It should be noted that the cross-section of the top of the material guide trough 5 is larger than the cross-section of the forming mold 31. During the flipping of the forming mold 31, if any medicine escapes from the forming hole 35, it can be ensured that the fallen tablets directly enter the forming trough and are finally introduced into the collecting bucket 6.

[0051] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
