Description

Technical Field

[0001] The present application relates to the technical field of tablet presses, and particularly to high-speed rotary tablet presses. Background Art

[0002] A tablet press is a device for manufacturing tablets and is widely used in multiple industrial fields such as pharmaceuticals, food processing, and chemical engineering.

[0003] In existing tablet presses, multiple sets of die sets arranged in a circular shape are installed on a working turntable. The tails of each upper and lower punch are controlled by fixed lifting guide rails. The working turntable is driven by a transmission device to rotate, causing the upper and lower punches to rotate synchronously with it. At the same time, they are controlled by the guide rails to perform axial lifting movements. Granules in the filling hopper are continuously added to the die. There are pressing wheels above the upper punch and below the lower punch. When each punch rotates to its respective pressing wheel, the material is continuously pressed into tablets and continuously discharged. Generally speaking, the working principle of a rotary tablet press is to compress powder or granules into tablets inside the rotary tablet press and, through steps such as vibration, separation, and shaping, finally obtain tablets of a specified shape and size.

[0004] However, during the stamping process, dust or dirt will be generated. The dust or dirt remains in the tablet press, and when the tablets are discharged from the discharge port, they are likely to carry dust or dirt. After collecting the tablets, dust removal treatment is still required, resulting in low work efficiency. Summary of the Invention

[0035] The following further Figure 1-7 describes the present application in detail with reference to the attached

[0036] The embodiment of the present application discloses a high-speed rotary tablet press.

[0037] Embodiment 1 Refer to Figure 1 and Figure 2, High-speed rotary tablet press, including a tablet press body 1, a discharging member 2, a sieve frame 3, a sieve mesh 4 and a driving assembly 5. Among them, a discharging port is provided on one side of the tablet press body 1, and after the tablets are formed, they are discharged from the discharging port. The discharging member 2 is connected to the tablet press body 1 through the discharging port for discharging the tablets. The sieve frame 3 is installed inside the discharging member 2, and the sieve mesh 4 slides in the sieve frame 3. The sieve mesh 4 is inclined, with one end of the sieve mesh 4 close to the discharging port, and the horizontal height of the end of the sieve mesh 4 close to the discharging port is higher than the horizontal height of the end of the sieve mesh 4 far from the discharging port, which is convenient for the tablets to be discharged from the end of the discharging member 2 far from the tablet press body 1. The sieve frame 3 is inclined, and the inclination angle of the sieve frame 3 is the same as the inclination angle of the sieve mesh 4. A transition plate 21 is fixedly connected to the inner wall of the discharging member 2, and the transition plate is located between the discharging port and the sieve frame 3. The top wall of the transition plate 21 is inclined, which is convenient for conveying the tablets to the sieve mesh 4. A partition assembly 6 is provided on the top of the sieve mesh 4, and the partition assembly 6 is connected to the sieve frame 3. The partition assembly 6 is used to form a zigzag channel for the tablets to be discharged at the top of the sieve mesh 4. The driving assembly 5 is connected to the discharging member 2, and the driving assembly 5 is used to drive the sieve mesh 4 to move reciprocally.

[0038] When the tablets are discharged from the discharging port, the tablets pass through the discharging port and move to the transition plate 21. Under the action of the tablets themselves and the pushing of the adjacent tablets discharged from the tablet press body 1, the tablets moving to the transition plate 21 fall onto the sieve mesh 4. The sieve mesh 4 is inclined. Under the action of the gravity of the tablets, the tablets move towards the end far from the discharging port. The tablets move to the zigzag channel, so that the tablets can fully shake off the dust adhering to their surfaces during the discharging process. At the same time, the driving assembly 5 drives the sieve mesh 4 to move reciprocally, further enhancing the vibration effect of the sieve mesh 4, improving the cleanliness of the tablets, increasing the discharging efficiency of the tablets, reducing the time for subsequent dust removal treatment, and thus improving the overall production efficiency.

[0039] A cleaning window is provided on the top of the tablet press body 1. The cleaning window is located at the working turntable, which is convenient for cleaning the working turntable after the operation stops. In addition, for the convenience of observing the working state inside the machine and protecting the inside of the machine from external pollution, a transparent window 11 is hinged at the cleaning window.

[0040] Refer to Figure 2 and Figure 3, the driving assembly 5 includes a driving member 51, a rotating rod 52, a pushing member 53, a reciprocating member 54 and a reciprocating spring 55. The driving member 51 is fixedly connected to one end of the discharging member 2 near the discharging port. The output end of the driving member 51 is fixedly connected to the rotating rod 52. The length direction of the rotating rod 52 is parallel to the inclination direction of the sieve mesh 4. The end of the rotating rod 52 away from the driving member 51 is rotatably connected to the inner wall of the discharging member 2. One end of the pushing member 53 is fixedly connected to the outer wall of the rotating rod 52. The reciprocating member 54 is fixedly connected to the bottom of the sieve mesh 4. The reciprocating spring 55 is located on one side of the moving direction of the tablets. One end of the reciprocating spring 55 is fixedly connected to the sieve mesh 4, and the end of the reciprocating spring 55 away from the sieve mesh 4 is fixedly connected to the sieve frame 3. The pushing member 53 pushes the reciprocating member 54 to make the sieve mesh 4 move reciprocally. In this instance, the driving member 51 is a small electric motor.

[0041] When the tablets move to the sieve mesh 4, the driving member 51 drives the rotating rod 52 to rotate. The rotation of the rotating rod 52 drives the pushing member 53 to rotate. When the pushing member 53 rotates and passes by the reciprocating member 54, the pushing member 53 contacts the reciprocating member 54 and pushes the reciprocating member 54 to move. When the pushing member 53 separates from the reciprocating member 54, under the action of the reciprocating spring 55, the reciprocating member 54 resets, so that the reciprocating member 54 drives the sieve mesh 4 to move reciprocally, realizing the dust screening operation. The reciprocating spring 55 provides stability and resilience for the reciprocating movement of the sieve mesh 4, improves the screening efficiency and dust removal effect of the sieve mesh 4, reduces the dust carried by the tablets during discharging, and thus improves the working efficiency and product quality of the entire tablet press.

[0042] Refer to Figure 3 and Figure 4 , to reduce the damage of the reciprocating spring 55 to the sieve mesh 4, the sieve mesh 4 includes a frame part 41 and a dust screening part 42. The frame part 41 is in the shape of a rectangular frame. The inner wall of the frame part 41 is fixedly connected to the outer wall of the dust screening part 42. There is a gap between the outer wall of the dust screening part 42 at the end away from the discharging port and the inner wall of the frame part 41 at the end away from the discharging port, which is convenient for dust or dirt to fall from the gap between the two. A sliding groove 31 is provided on the inner wall of the sieve frame 3. The frame part 41 is inserted into the sliding part, and the outer wall of the frame part 41 is slidably connected to the inner groove wall of the sliding groove 31. The outer wall of the frame part 41 is fixedly connected to a return spring. The end of the return spring away from the frame part 41 is fixedly connected to the groove wall of the sliding groove 31 away from the groove opening. The reciprocating member 54 is fixed to the bottom wall of the frame part 41. When the reciprocating member 54 moves through the pushing member 53, the reciprocating member 54 drives the frame member to move, and the frame member drives the dust screening part 42 to move, thereby realizing the dust screening operation of the dust screening part 42 on the tablets.

[0043] The reciprocating member 54 is inclined in contact with one side of the pushing member 53. One end of the reciprocating member 54 away from the frame portion 41 is inclined in a direction away from the pushing member 53. A vibration groove 22 is formed in the inner wall of the discharging member 2. The sieve frame 3 is inserted into the vibration groove 22. The side wall of the sieve frame 3 away from the sliding groove 31 abuts against the groove wall of the vibration groove 22 away from the notch. A first spring 32 is fixedly connected to the top wall of the sieve frame 3. One end of the first spring 32 away from the sieve frame 3 is fixedly connected to the top wall of the vibration groove 22. A second spring 33 is fixedly connected to the bottom wall of the sieve frame 3. One end of the second spring 33 away from the sieve frame 3 is fixedly connected to the bottom wall of the vibration groove 22.

[0044] When the pushing member 53 cannot push the frame portion 41, and at this time the pushing member 53 still contacts the pushing member 53, due to the continuous pushing action of the pushing member 53, the reciprocating member 54 is inclined. So when the pushing member 53 continuously pushes the reciprocating member 54, under the action of the inclined surface of the reciprocating member 54, the sieve frame 3 moves upward toward the top through the frame portion 41, the first spring 32 is compressed, and the second spring 33 extends. When the reciprocating member 54 separates, the first spring 32 releases the compression, and the second spring 33 is compressed. Thus, the sieve frame 3 can stably vibrate up and down in the vibration groove 22, and further makes the dust screening portion 42 vibrate up and down, effectively reducing the problem of dust adhesion generated by friction during the discharging process of the tablets, improving the cleanliness of the tablets, enabling the tablets on the dust screening portion 42 to smoothly pass through the zigzag channel, reducing the occurrence of blockage, and thus improving the discharging efficiency.

[0045] To enable the pushing member 53 to smoothly lift the sieve frame 3, a rotating roller 541 is rotatably connected to one end of the reciprocating member 54 away from the frame portion 41. The inclined side of the pushing member 53 is tangent and smoothly transitions with the rotating roller 541. One end of the pushing member 53 away from the rotating rod 52 is arc-shaped. The rotating roller 541 rolls on one side of the arc surface of the rotating rod 52. The rotating roller 541 cooperates with the arc surface of the pushing member 53 to reduce the friction between the rotating roller 541 and the pushing member 53, making the pushing process of the frame portion 41 smooth to the pushing process of the sieve frame 3 and improving the stability of dust screening.

[0046] A dust removal port is formed at the bottom of the discharging member 2. A dust guiding member 23 is arranged at the dust removal port. The dust guiding member 23 is fixedly connected to the inner wall of the discharging member 2. The top wall of the dust guiding member 23 is arc-shaped, and the arc surface of the dust guiding member 23 located directly below the rotating rod 52 is adapted to the rotation circumference of the pushing member 53, so that when the pushing member 53 rotates to the top wall of the dust guiding member 23, the pushing member 53 fits with the arc surface of the dust guiding member 23. A dust outlet 231 is formed through the top wall and the bottom wall of the dust guiding member 23, and the dust outlet 231 is located directly below the rotating rod 52.

[0047] When the pushing member 53 moves as the rotating rod 52 rotates, it will continuously slide across the arc surface of the dust guiding member 23, thereby effectively guiding dust and dirt into the dust outlet 231 of the dust guiding member 23, effectively preventing dust accumulation, achieving efficient dust removal, ensuring the smoothness of the discharging process and the cleanliness of the tablets, and improving production efficiency.

[0048] In this embodiment, the guiding member is made of soft rubber. When dust or dirt accumulates on the guiding member, under the action of gravity, the guiding member bends, and the dust or dirt can directly fall from the top wall of the guiding member.

[0049] The inner wall of the discharging member 2 is fixedly connected with a lapping member 24. The lapping member 24 is located at the bottom of the discharging member 2. An installation groove is formed in the inner wall of the discharging member 2 away from the lapping member 24. A dust collection box 7 is arranged at the bottom of the discharging member 2. The dust collection box 7 is located within the dust removal port. The dust outlet 231 is located at the top of the dust collection box 7. The dust and dirt falling from the dust outlet 231 directly fall into the dust collection box 7. A lapping plate 71 is fixedly connected to the outer wall of the dust collection box 7. The lapping plate 71 is lapped on the lapping member 24. There is a gap between the lapping plate 71 and the dust guiding member 23. A pressing spring 72 is fixedly connected to one side of the dust collection box 7 away from the lapping plate 71. A pressing member 73 is slidably connected to the end of the pressing spring 72 away from the dust collection box 7. The side of the pressing member 73 away from the pressing spring 72 abuts against the inner wall of the discharging member 2. An installation member 74 is fixedly connected to the side of the pressing member 73 close to the discharging member 2. The installation member 74 is inserted into the installation groove. The installation member 74 is adapted to the installation groove. The groove wall of the installation groove abuts against the installation member 74. One end side of the dust collection box 7 abuts against the inner wall of the discharging member 2 away from the discharge port. When installing the dust collection box 7, press the pressing member 73, insert the dust collection box 7 into the dust removal port, let the lapping plate 71 lap on the lapping member 24, move the dust collection box 7 so that one end side of the dust collection box 7 away from the discharge port abuts against the inner wall of the discharging member 2 away from the discharge port, thereby providing guidance for the installation position of the dust collection box 7. Release the pressing member 73, and the installation member 74 is inserted into the installation groove, thereby increasing the installation speed of the dust collection box 7.

[0050] Refer to Figure 5 , the partition assembly 6 includes a plurality of partition sheets 61. The bottom wall of the partition sheet 61 is connected to the top wall of the sieve frame 3. The end of the partition sheet 61 away from the sieve frame 3 is located at the top of the dust screening part 42. Along the discharging direction of the tablets, the partition sheets 61 are distributed on both sides of the sieve frame 3 and are staggered to form a serpentine channel.

[0051] When the tablets move from the discharge port to the partition sheet 61, the tablets impact on the partition sheet 61, reducing the possibility of dust or dirt adhering to the tablets and improving the cleanliness of the tablets. At the same time, the design of the serpentine channel helps to slow down the discharging speed of the tablets, making them fall into the dust collection box 7 more smoothly, reducing the impact force and the risk of tablet breakage.

[0052] The implementation principle of Embodiment 1 of this application is as follows: When the tablets are discharged from the discharge port, they fall onto the dust screening part 42 through the transition plate 21. The driving member 51 drives the pushing member 53 to rotate, thereby moving the reciprocating member 54. The movement of the reciprocating member 54 drives the movement of the dust screening part 42. When the pushing member 53 cannot continuously push the frame part 41 to move, the pushing member 53 pushes the screen frame 3 towards the top, and then drives the frame part 41 towards the top. The pushing member 53 rolls on the rotating roller 541 to reduce friction. When the first spring 32 is compressed and the pushing member 53 separates from the rotating roller 541, the reciprocating spring 55 resets. Under the action of the reciprocating spring 55, the dust screening part 42 performs a dust screening motion. At the same time, the first spring 32 releases its elasticity, driving the screen frame 3 to vibrate up and down, and then driving the dust screening part 42 to vibrate up and down, causing the tablets to roll over multiple times during discharge. Also, during the movement of the tablets, they impact on the baffle piece 61, reducing the possibility of dust or dirt adhering to the tablets, improving the cleanliness of the tablets, increasing the discharge efficiency of the tablets, reducing the time for subsequent dust removal treatment, and thus enhancing the overall production efficiency.

[0053] Embodiment 2 Referring to Figure 6 and Figure 7 , the difference from Embodiment 1 is that the baffle assembly 6 includes a connecting plate 62 and a plurality of baffle columns 63. The connecting plate 62 is in a U shape with the opening facing downwards. The two ends of the opening of the connecting plate 62 are fixedly connected to the top wall of the screen frame 3. The inner wall of the connecting plate 62 is fixedly connected to one end of the baffle column 63. The baffle columns 63 are arranged and distributed inside the connecting plate 62. The baffle columns 63 are arranged vertically with respect to the dust screening part 42, so that the baffle columns 63 are evenly arranged and distributed on the top of the screen mesh 4, thereby forming multiple channels for the tablets to move on the top of the dust screening part 42, effectively preventing dust or dirt from discharging together with the tablets, ensuring the cleanliness of the tablets, reducing the subsequent dust removal treatment process, and improving the production efficiency.

[0054] The implementation principle of Embodiment 2 of this application is as follows: By setting the baffle columns 63, the tablets need to roll over multiple times during discharge, thereby effectively removing the dust on the surface of the tablets. The design of the baffle columns 63 forms multiple channels for the tablets to move on the top of the dust screening part 42, reducing the possibility of tablet blockage, increasing the discharge efficiency of the tablets, and thus enhancing the overall production efficiency.

[0055] The above are all the preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
