Description

Technical Field

[0001] This utility model relates to the field of tablet presses, and more particularly to an adjustable tablet press. Background Technology

[0002] A tablet compressor is a machine that compresses powdered and granular materials into tablets. It typically consists of a feeding system, a pressure system, a mold, and a control system. Its working principle is that the rotation of the turntable causes the granular material to flow into the middle mold through the feeder. Then, under the action of the pressure rollers and multiple sets of punches, the material is compressed into tablets.

[0003] Powder is formed into tablets by pressing. For example, Chinese Patent Publication No. CN220031270U discloses a tablet press with adjustable tablet thickness, which includes a worktable and a tablet-making component. The tablet-making component is mounted on the worktable. The tablet-making component includes a power assembly, a turntable, an upper punch track, a lower punch track, a drive unit, an upper punch assembly, a lower punch assembly, and a rotating shaft. The turntable, the upper punch track, and the lower punch track are all mounted on the rotating shaft, and the turntable, the upper punch track, and the lower punch track are coaxially arranged. The rotating shaft is drivably connected to the drive unit, so that the drive unit drives the rotating shaft to rotate, thereby causing the turntable, the upper punch track, and the lower punch track to rotate synchronously. The upper punch assembly is mounted on the upper punch track, and the lower punch assembly is mounted on the lower punch track. Therefore, when the rotating shaft drives the upper punch track and the lower punch track to rotate...

[0004] In practice, considering that tablets are formed by pressing powder, some residual powder will be discharged when the tablets are fed. The powder and tablets cannot be screened and collected, which affects the purity of the tablets and the subsequent screening will affect the processing efficiency, making it impractical.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An adjustable tablet press includes a frame 1, inside which a stamping device 2 and a feeding component 3 are arranged. The stamping device 2 forms tablets by stamping powder, and the feeding component 3 is used to feed the tablets.

[0023] The feeding component 3 includes a feeding cylinder 31, which is detachably connected to the frame 1 via a fixing component 4. The feeding cylinder 31 has a pair of feeding channels 32 inside, one of which is connected to an external vacuum cleaner for cleaning residual powder. A filter 5 and a cleaning component 6 are provided at the top of the feeding channel 32.

[0024] The filter section 5 is used to stop the tablets, and the cleaning component 6 is used to clean the filter section 5 to prevent clogging.

[0025] It should be added that, in the prior art, in order to facilitate the observation of the tableting process and the maintenance of the stamping device 2, a transparent acrylic plate that can be opened and closed is provided on the periphery of the frame 1 through a window for easy observation. Of course, by opening and closing the acrylic plate, the feed cylinder 31 can be disassembled and assembled.

[0026] Furthermore, the fixing component 4 includes a pair of fixing parts 41, which are fixedly connected to the side of the frame 1. A through groove is provided on the top of the pair of fixing parts 41 and between the opposite sides. The feed cylinder 31 has extension parts 311 on both sides, which are inserted into the fixing parts 41 through the through groove.

[0027] Furthermore, one of the extension portions 311 and the end face of the fixing portion 41 are provided with a connecting hole 312, and a positioning glass bead 42 is embedded in the side of the frame 1, with the positioning bead end of the positioning glass bead 42 engaging with the connecting hole 312.

[0028] It is worth mentioning that the fixing part 41 has a rectangular structure. The fixing part 41 is used to receive the feeding cylinder 31, and the fixing part 41 also works with the positioning glass bead 42 to fix the feeding cylinder 31. Of course, the extension parts 311 on both sides of the feeding cylinder 31 are fitted with the through groove in the fixing part 41 to prevent the gap from being too large, causing the extension parts 311 without the positioning glass bead 42 to rotate with the telescopic end of the positioning glass bead 42 as the midpoint.

[0029] It should be added that the stamping device 2 includes a lower punch rail, which is rotatably connected to the top platform of the frame 1. A baffle is also fixedly connected to the top of the frame 1 above the lower punch rail. After the tablet is ejected from the mold slot, the baffle feeds the tablet into the feeding cylinder 31 under the action of the rotation of the lower punch rail. Of course, the working principle of the stamping device 2 is the same as that of the prior art in terms of feeding and ejecting tablets, which will not be described in detail here.

[0030] More specifically, the feeding channels 32 are arranged in parallel, and their top openings are all connected to the feed inlet of the feeding cylinder 31. The top opening of the feeding channel 32 located on the inner side is closed, and several through slots are formed to form the filter section 5. The filter section 5 is arranged at an angle.

[0031] Specifically, the inner feeding channel 32, located near the frame 1, is used to clean powder in conjunction with the vacuum cleaner, while the outer feeding channel 32 is used to guide and collect tablets.

[0032] In general, the cleaning assembly 6 includes a support plate 61. One end of the support plate 61 is rotatably connected to the top of the inner wall of the feed cylinder 31 via a pin and a torsion spring. Guide rods 611 are fixed on both sides at the other end of the support plate 61. The side of the feed cylinder 31 is provided with an arc-shaped groove 313, and the guide rods 611 are slidably connected in the arc-shaped groove 313.

[0033] It is worth mentioning that the support plate 61 is in contact with the top of the inner wall of the feed cylinder 31 under the action of the torsion spring, so as to avoid blocking the feeding of the tablets. The free end of the guide rod 611 is fixedly connected with a protrusion, which facilitates the rotation of the support plate 61. The support plate 61 rotates along the arc groove 313, and the cleaning brush 62 cleans the filter section 5 to prevent unformed tablet particles from clogging the channel.

[0034] Finally, it also includes a cleaning brush 62. A pair of spring telescopic rods 612 are fixedly connected to one end of the support plate 61 near the filter part 5. The telescopic ends of the spring telescopic rods 612 are fixedly connected to the cleaning brush 62. The brush surface of the cleaning brush 62 can abut against the filter part 5.

[0035] The spring telescopic rod 612 includes a housing, a telescopic end, and a spring. The other end of the telescopic end is slidably connected inside the housing, and the spring is fixedly connected between its end and the inner side of the housing. By sliding the telescopic end and the housing end together, the brush surface of the cleaning brush 62 is ensured to contact the filter part 5.

[0036] Working method: During operation, powder is fed to the stamping device 2 through the feeding port at the top of the frame 1. The stamping device 2 forms tablets from the powder by stamping and then conveys the tablets to the feeding cylinder 31 for feeding through the baffle.

[0037] When the tablets enter the feeding cylinder 31, they will enter the feeding cylinder 31 together with some residual powder. This part of the powder will be separated from the tablets and collected by the vacuum cleaner and the filter section 5.

[0038] After prolonged use, the feeding cylinder 31 can be disassembled. Press the telescopic end of the positioning glass bead 42 to unlock the extension part 311, and then the feeding cylinder 31 can be disassembled.

[0039] Finally, the support plate 61 is driven to rotate half a revolution by the drive guide rod 611, and the support plate 61 uses the cleaning brush 62 to clean the filter section 5.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
