Description

Technical Field

[0001] This application relates to the technical field of tablet presses, and particularly to a nutritional tablet press. Background Art

[0002] A tablet press is a device used to press powdery or granular materials into tablets, and has wide applications in industries such as pharmaceuticals, food, and chemicals. It can ensure the uniform distribution of drug components, and through precise control of pressure and molds, make the tablets reach the specified shape, size, weight, and hardness, so as to meet the quality standards and efficacy requirements of drugs.

[0003] Currently, in the process of pharmaceutical processing by existing tablet presses, when the tablet pressing device in the tablet press completes tablet pressing, there are often residual drug powders on the pressure-bearing platform inside the tablet press. When new tablets need to be pressed, the residual powders are easily mixed into the new materials, contaminating the drugs for the next tablet pressing, resulting in a decrease in the quality of the tablets pressed by the tablet press, which has obvious deficiencies. Utility Model Content

[0004] In order to improve the tablet pressing quality of the tablet press, this application provides a nutritional tablet press.

[0005] The nutritional tablet press provided by this application adopts the following technical solutions:

[0006] A nutritional tablet press includes a tablet pressing box and a tablet pressing assembly. The tablet pressing assembly includes a pressure-bearing plate disposed inside the tablet pressing box. A plurality of grooves are formed on the pressure-bearing plate. A cylinder is disposed on the top surface of the tablet pressing box. The output shaft of the cylinder is fixedly connected to a pressing plate. Pressing blocks corresponding to the plurality of grooves one by one are disposed on the surface of the pressing plate facing the pressure-bearing plate. The upper and lower surfaces of the pressure-bearing plate respectively enclose a tablet pressing area and a discharging area with the inner side wall of the tablet pressing box. A discharging assembly for unloading tablets is disposed in the discharging area. A powder suction assembly is disposed on the tablet pressing box. The powder suction assembly includes a suction pump. The suction end of the suction pump is communicated with a powder collecting box. A corrugated pipe is communicated with the powder collecting box. A powder suction plate is slidably connected to the surface of the pressure-bearing plate. A cavity is formed inside the powder suction plate. One end of the corrugated pipe extends into the tablet pressing box and is communicated with the cavity. A plurality of powder suction holes are formed at the bottom of the powder suction plate. The powder suction holes are internally communicated with the cavity. A driving assembly is disposed in the tablet pressing area. The driving assembly drives the powder suction plate to reciprocate along the surface of the pressure-bearing plate.

[0007] By adopting the above technical solution, when pressing tablets, the air cylinder starts to drive the pressing block to move towards the inside of the groove, and the powdery material is compressed into tablets by mechanical pressure. After the pressing is completed, the discharging assembly transfers the pressed tablets to the discharging area. Subsequently, the suction pump and the driving assembly are started. The suction pump makes the cavity in a negative pressure state through the corrugated pipe. During the process that the driving assembly drives the powder suction plate to move along the surface of the bearing plate, the powder remaining on the bearing plate and in the groove moves along the negative airflow into the cavity and is finally sucked into the powder collecting box by the suction pump. Such a setting realizes the all-round cleaning of the powder remaining on the bearing plate and inside the groove, avoids the phenomenon that the remaining powder mixes into the new material and contaminates the new drug, and thus improves the quality of the tablets pressed by the tablet press each time.

[0008] Optionally, the driving assembly includes a screw rod and a guide rod respectively arranged at opposite ends of the bearing plate. The screw rod is rotatably connected in the tablet pressing area. One end of the powder suction plate is threadedly connected to the screw rod, and the other end is slidably connected to the guide rod.

[0009] By adopting the above technical solution, after the tablet pressing is completed, the first motor starts to drive the screw rod to rotate forward or backward. The rotation of the screw rod drives the powder suction plate to reciprocate along the surface of the bearing plate. During the movement, the powder suction plate sucks the powder remaining on the surface of the bearing plate. The setting of the driving assembly expands the powder suction range of the powder suction plate, increases the probability that the remaining powder is sucked by the powder suction plate, thereby reducing the possibility of powder residue and further improving the tablet pressing quality of the tablet press.

[0010] Optionally, an installation plate is arranged on the powder suction plate, and a plurality of brush plates are arranged on the installation plate. The brush head parts of the brush plates abut against the surface of the bearing plate.

[0011] By adopting the above technical solution, during the process that the powder suction plate reciprocates along the surface of the bearing plate, the powder suction plate drives the installation plate to move, the installation plate drives the brush plates to move, and the brush plates scatter the powder accumulated on the surface of the bearing plate during the movement, reducing the possibility that the powder suction plate is not easily sucked due to powder accumulation, and thus further improving the tablet pressing quality of the tablet press.

[0012] Optionally, the rotating assembly includes a plurality of connecting rods rotatably connected to the installation plate. The plurality of connecting rods are arranged in one-to-one correspondence with the brush plates. One end of the connecting rod is connected to the brush plate, and the other end is fixedly connected with a gear. The plurality of gears are rotatably arranged on the surface of the installation plate, and adjacent gears are meshed with each other. A rack plate is arranged on the inner side wall of the tablet pressing box, and the rack plate is meshed with the gear close to the rack plate.

[0013] By adopting the above technical solution, the movement of the mounting plate drives the gear to move along the length of the rack plate. Since the rack plate is fixedly connected to the inner wall of the tablet pressing box, the rack plate drives the moving gear to rotate. At the same time, under the transmission action of multiple gears meshing with each other, multiple gears rotate synchronously and drive the connecting rod to rotate. The connecting rod rotates the brush plate to clean the residual powder on the surface of the pressure plate. The contact angle between the rotating brush and the powder changes continuously, so that the accumulated powder is subjected to force in different directions. The accumulated state of the powder is more easily broken up by the brush, thereby further reducing the possibility that the accumulated powder is not easily absorbed by the powder suction plate, and further improving the tableting quality of the tablet press.

[0014] Optionally, a discharge trough connected to the plurality of grooves is formed on the surface of the pressure plate near the discharge area, and the unloading assembly includes two rotating shafts, which are rotatably connected to opposite sides of the discharge trough respectively, and a support plate is fixedly connected to the outer surface of each rotating shaft. When the two support plates abut against each other, the two support plates jointly block the grooves, and one end of each rotating shaft extends out of the tablet pressing box and is fixedly connected to a worm gear. The outer side wall of the tablet pressing box is rotatably connected to a worm that meshes with the two worm gears, and the spiral patterns at both ends of the worm gear have opposite rotation directions.

[0015] By adopting the above technical solution, during tableting, the support plate carries the tablets. After tableting is completed, the worker rotates the worm. When the worm rotates, it drives the meshing worm wheel to rotate in the opposite direction. The worm wheel drives the rotating shaft to rotate, and the rotating shaft drives the two support plates to rotate toward the discharge area. At this time, the support plate is continuously tilted, and the tablets on the surface of the support plate roll along the support plate to the discharge area. Then the worker starts the cleaning component for cleaning. This arrangement makes it convenient for the workers to transfer the compressed tablets in a centralized manner and to remove the tablets later.

[0016] Optionally, mounting rods are provided on the opposite inner side walls of the discharge area, a filter screen is provided between two mounting rods, the pore size of the filter screen is larger than the diameter of the tablet, and a discharge door is hinged on the surface of the tablet pressing box located in the discharge area.

[0017] By adopting the above technical solution, during the process of transferring the tablets to the discharging area, part of the drug powder remaining on the surface of the tablets will fall off the tablets as the tablets fall, and the powder will accumulate at the bottom of the tablet pressing box through the filter holes of the filter net. At the same time, the filter net will receive the fallen tablets, effectively avoiding the possibility of the drugs falling too high and breaking. Then the workers open the box door and take out the tablets from the filter net.

[0018] Optionally, sliding grooves that are slidably engaged with the mounting rods are formed in the side walls of the discharging area. Springs are provided at both opposite ends of the sliding grooves. One end of each spring is connected to the inner side wall of the sliding groove, and the other end is connected to the mounting rod. Cams are rotatably connected in the sliding grooves. When the protruding ends of the cams abut against the mounting rods, the springs are in a compressed state. In the natural state of the springs, the filter net is in a flat state.

[0019] By adopting the above technical solution, when the protruding end of the cam rotates close to the mounting rod, the cam pushes the mounting rod to move towards the spring, and the spring is compressed. At this time, the filter net changes from a flat state to a hanging state. When the protruding end of the cam rotates away from the mounting rod, the thrust force on the spring disappears, and the spring instantaneously resets and pushes the mounting rod to move towards the cam. The mounting rod pulls the filter net flat again. In the cycle of the filter net changing from flat to hanging, the powder remaining on the tablet is shaken out of the tablet, thereby reducing the occurrence of powder remaining on the pressed tablet, and further improving the tablet pressing quality of the tablet press.

[0020] Optionally, polytetrafluoroethylene coatings are applied to both the support plate and the bearing plate.

[0021] By adopting the above technical solution, the polytetrafluoroethylene coating has an extremely low coefficient of friction and good chemical stability, effectively reducing the adhesion of the powder, thereby reducing the possibility of powder residue.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By providing a powder suction assembly and a driving assembly in the present application, the driving assembly drives the powder suction plate to reciprocate along the surface of the bearing plate. When moving, the powder suction plate sucks the drug powder remaining on the surface of the bearing plate into the powder collection box. Such a setting realizes the comprehensive cleaning of the powder remaining on the bearing plate and inside the groove, avoiding the phenomenon that the remaining powder mixes into the new material and contaminates the new drug, thereby improving the tablet quality of each tablet pressing of the tablet press;

[0024] 2. By providing a rotating assembly and a brush plate in the present application, the movement of the powder suction plate drives the movement of the brush plate. The brush part of the brush plate sweeps the powder accumulated on the surface of the bearing plate, reducing the possibility that the powder suction plate is not easily sucked due to powder accumulation, thereby further improving the tablet pressing quality of the tablet press;

[0025] 3. By providing a cam, a spring and a mounting rod in the present application, the cam is used to push the mounting rod to move, and the spring drives the mounting rod to reset. In this way, the conversion of the filter net from a flat state to a hanging state is realized, and the powder remaining on the tablet is shaken out of the tablet, thereby reducing the occurrence of powder remaining on the pressed tablet, and further improving the tablet pressing quality of the tablet press.

Detailed implementation manners

[0032] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 for a more detailed description of the present application.

[0033] The embodiment of the present application discloses a nutritional tablet pressing and dust removal device.

[0034] Refer to Figure 1 and Figure 2, A dust removal device for pressing nutritional tablets includes a pressing box 1. Inside the pressing box 1, there is a pressing component 2. The pressing component 2 includes a bearing plate 21 fixedly installed inside the pressing box 1. The upper and lower end faces of the bearing plate 21 respectively enclose a pressing area 3 and a discharging area 4 with the inner side walls of the pressing box 1. An inlet door 101 and an outlet door 102 are respectively hinged to the areas of the pressing box 1 located in the pressing area 3 and the discharging area 4. A plurality of grooves 211 for accommodating raw material powder are formed on the surface of the bearing plate 21. A cylinder 22 is fixedly connected to the top surface of the pressing box 1. The output shaft of the cylinder 22 is fixedly connected to a pressing plate 23. The pressing plate 23 is slidably connected inside the discharging area 4. A pressing block 24 corresponding to each groove 211 is fixedly connected to the surface of the pressing plate 23 facing the bearing plate 21. A discharging component 5 for unloading tablets is arranged on the bottom surface of the bearing plate 21.

[0035] During pressing, the worker opens the inlet door 101 to add drug powder into the grooves 211, then closes the inlet door 101 and starts the cylinder 22. The cylinder 22 drives the pressing block 24 to move towards the inside of the grooves 211. The mechanical pressure acting on the drug powder by the pressing block 24 compresses the raw material powder into tablet pills. After the tablets are formed, the discharging component 5 transfers the pressed tablets to the discharging area 4, and the worker opens the outlet door 102 to take out the pressed tablets.

[0036] Refer to Figure 2 and Figure 3 , An absorbing powder component 6 is arranged in the pressing area 3. The absorbing powder component 6 includes an air suction pump 61 fixedly installed on the outer side wall of the pressing box 1. The air suction end of the air suction pump 61 is communicated with a powder collecting box 62. The powder collecting box 62 is installed on the outer side wall of the pressing box 1. A corrugated pipe 63 is communicated with the powder collecting box 62. A powder absorbing plate 64 is slidably connected to the surface of the bearing plate 21. The length direction of the powder absorbing plate 64 is perpendicular to the length direction of the bearing plate 21. The length of the powder absorbing plate 64 covers a plurality of grooves 211. A cavity 641 is formed inside the powder absorbing plate 64. One end of the corrugated pipe 63 extends into the pressing box 1 and is communicated with the cavity 641. A plurality of powder absorbing holes 642 are formed at the bottom of the powder absorbing plate 64. The plurality of powder absorbing holes 642 are all communicated with the cavity 641. A driving component 7 is arranged in the pressing area 3. The driving component 7 drives the powder absorbing plate 64 to reciprocate along the surface of the bearing plate 21.

[0037] Refer to Figures 2 to 4 , The driving component 7 includes screw rods 71 and guide rods 72 arranged at opposite ends of the bearing plate 21. The screw rods 71 are rotatably connected to the surface of the bearing plate 21. The guide rods 72 are fixedly installed on the inner side wall of the pressing box 1. One end of the powder absorbing plate 64 is threadedly connected to the screw rod 71, and the other end is slidably connected to the guide rod 72. A first motor 73 is fixedly installed on the outer side wall of the pressing box 1. The output shaft of the first motor 73 is coaxially fixedly connected to the screw rod 71.

[0038] After the tablet pressing is completed, the worker starts the suction pump 61 and the first motor 73. The first motor 73 starts to drive the screw 71 to rotate forward or backward. The rotation of the screw 71 drives the powder suction plate 64 to reciprocate along the surface of the bearing plate 21. The suction pump 61 makes the cavity 641 form a negative pressure state through the corrugated pipe 63. During the movement of the powder suction plate 64, the residual powder in the bearing plate 21 and the groove 211 moves along the negative airflow into the cavity 641 and is finally sucked into the powder collection box 62 by the suction pump 61. This setting realizes the comprehensive cleaning of the residual powder inside the bearing plate 21 and the groove 211, avoiding the phenomenon that the residual powder mixes into the new material and contaminates the new drug, thereby improving the quality of the tablets pressed by the tablet press each time.

[0039] Referring to Figures 2 to 4 , on the end face of the powder suction plate 64 perpendicular to the length direction, a mounting plate 8 is fixedly connected. A plurality of connecting rods 9 are rotatably connected inside the mounting plate 8. One end of each connecting rod 9 is fixedly installed with a brush plate 91. The brush part of the brush plate 91 is made of a flexible material. When the mounting plate 8 moves to directly above the groove 211, the brush of the brush plate 91 abuts against the inner bottom wall of the groove 211. The end of the connecting rod 9 away from the brush plate 91 is fixedly connected with a gear 92. A plurality of gears 92 are rotatably connected to the surface of the mounting plate 8 and are meshed with each other adjacent to each other. A rack plate 10 is meshed with the outermost gear 92. The rack plate 10 is fixedly installed on the inner side wall of the tablet pressing box 1. The length direction of the rack plate 10 is parallel to the length direction of the screw 71.

[0040] During the movement of the powder suction plate 64 along the surface of the bearing plate 21, the powder suction plate 64 drives the mounting plate 8 to move along the length direction of the rack plate 10. The gear 92 meshed with the rack plate 10 on the mounting plate 8 rotates. At the same time, under the driving action of the meshing of a plurality of gears 92 with each other, a plurality of gears 92 rotate synchronously and drive the connecting rod 9 to rotate. The connecting rod 9 makes the brush plate 91 rotate to sweep the residual powder on the surface of the bearing plate 21. The contact angle between the rotating brush and the powder is constantly changing, so that the accumulated powder is subjected to forces in different directions, and the accumulated state of the powder is more likely to be scattered by the brush, reducing the possibility that the powder suction plate 64 is not easily sucked due to powder accumulation, thereby further improving the tablet pressing quality of the tablet press.

[0041] Referring to Figures 2 to 4The surface of the pressure plate 21 near the discharge area 4 is provided with a discharge trough 11 connected with a plurality of grooves 211. The discharge assembly 5 includes two rotating shafts 51, which are rotatably connected to the opposite side walls of the discharge trough 11. The outer surface of each rotating shaft 51 is fixedly connected with a support plate 52. The outer surfaces of the support plate 52 and the pressure plate 21 are coated with a polytetrafluoroethylene coating. The polytetrafluoroethylene coating has an extremely low friction coefficient and good chemical stability, which effectively reduces the adhesion of the powder. When the two support plates 5 2 are horizontally abutted against each other, the two support plates 52 jointly cover all the grooves 211, and the surface of the support plate 52 is in close contact with the bottom surface of the pressure plate 21, one end of each rotating shaft 51 extends out of the tablet pressing box 1 and is fixedly connected with a worm wheel 53, and a worm 54 meshing with the two worm wheels 53 is rotatably connected to the outer wall of the tablet pressing box 1, and the spiral patterns at both ends of the worm 54 rotate in opposite directions, and a second motor 55 is fixedly installed on the outer wall of the tablet pressing box 1, and the output shaft of the second motor 55 is coaxially fixedly connected with the worm 54.

[0042] During tableting, the support plate 52 carries the tablets. After tableting is completed, the worker starts the second motor 55, and the second motor 55 drives the worm 54 to rotate. When the worm 54 rotates, it drives the meshing worm wheel 53 to rotate in the opposite direction. The worm wheel 53 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the two support plates 52 to rotate toward the discharge area 4. At this time, the support plate 52 is continuously tilted, and the tablets on the surface of the support plate 52 roll along the support plate 52 into the discharge area 4. Then the worker starts the cleaning component for cleaning. This arrangement is convenient for workers to centrally transfer the compressed tablets and facilitate workers to take out the tablets later.

[0043] Reference Figure 5 , sliding grooves 12 are provided on the opposite side walls of the discharging area 4, and each sliding groove 12 is slidably connected with a mounting rod 13, and a filter screen 14 is connected between the two mounting rods 13, and the filter screen 14 is located directly below the discharging groove 11. The filter screen 14 is made of flexible material, and the aperture of the filter screen 14 is larger than the diameter of the tablet. Springs 121 are provided at the opposite ends of the sliding groove 12, one end of the spring 121 is fixedly connected to the inner wall of the sliding groove 12, and the other end is fixedly connected to the connecting rod 9. A cam 122 is rotatably connected to the side of the sliding groove 12 away from the spring 121. When the raised end of the cam 122 abuts against the mounting rod 13, the spring 121 is in a compressed state. When the spring 121 is in a natural state, the filter screen 14 is in a flat state. A third motor 15 is fixedly installed on the outer wall of the tablet pressing box 1, and the third motor 15 synchronously drives the two cams 122 to rotate through the transmission action of the pulley and the belt.

[0044] After the tablets are transferred to the discharging area 4, they fall onto the filter screen 14. Subsequently, the third motor 15 drives the two cams 122 to rotate synchronously through the pulley and the belt. When the convex ends of the cams 122 gradually approach the mounting rod 13, the cams 122 push the mounting rod 13 to move towards the spring 121, and the spring 121 is compressed. At this time, the filter screen 14 changes from a flat state to a hanging state. When the convex ends of the cams 122 disengage from the mounting rod 13, the thrust on the spring 121 disappears, and the spring 121 instantaneously resets and pushes the mounting rod 13 to move towards the cams 122. The mounting rod 13 pulls the filter screen 14 flat again. In the cycle state where the filter screen 14 changes from flat to hanging, the powder remaining on the tablets is shaken out of the tablets, thereby reducing the occurrence of powder remaining on the tablets after pressing, and further improving the tablet pressing quality of the tablet press.

[0045] The implementation principle of a nutritional tablet press in an embodiment of the present application is as follows: After tablet pressing is completed, the worker starts the suction pump 61 and the first motor 73. The first motor 73 starts to drive the screw rod 71 to rotate forward or backward. The rotation of the screw rod 71 drives the powder suction plate 64 to reciprocate along the surface of the bearing plate 21. The suction pump 61 makes the cavity 641 form a negative pressure state through the corrugated pipe 63. During the movement of the powder suction plate 64, the powder remaining in the bearing plate 21 and the groove 211 moves along the negative airflow into the cavity 641 and is finally sucked by the suction pump 61 into the powder collection box 62. Such a setting realizes the comprehensive cleaning of the powder remaining inside the bearing plate 21 and the groove 211, and avoids the occurrence of the phenomenon that the remaining powder mixes into the new material and contaminates the new drug, thereby improving the quality of the tablets pressed by the tablet press each time.

[0046] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
