Description

Technical Field

[0001] This utility model relates to the field of tablet press equipment technology, and in particular to a rotary tablet press that prevents material from sliding. Background Technology

[0002] Rotary tablet presses are commonly used solid dosage form production equipment in the pharmaceutical industry. They achieve material filling, compression, and demolding processes through the continuous rotation of a turntable, offering advantages such as high production efficiency and a high degree of automation. In actual production, operators can flexibly adjust the turntable's rotation speed to control production efficiency, and adjust the filling depth and tablet thickness to ensure tablet quality, according to the drug specifications. Furthermore, the mechanical buffer device equipped on the equipment effectively prevents damage to machine parts in the event of overload, ensuring safe operation of the equipment.

[0003] However, existing rotary tablet presses still have significant shortcomings in the tablet feeding process. Traditional rotary tablet presses rely primarily on baffles to prevent tablets from entering the feeding hopper after compression. However, these baffles are often simple, fixed structures lacking protective measures. When the rotary table rotates at high speed, tablets are easily deviated from their intended trajectory due to centrifugal force and inertia, sliding off the edge of the table. This results in scattered tablets that cannot be collected, causing material waste and potentially introducing contamination risks, affecting drug quality and production efficiency.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] like Figure 1-7 As shown, the present invention proposes a rotary tablet press to prevent material slippage. It includes a base 1, which serves as a basic load-bearing component. A mounting seat 10 is fixedly installed on the base 10. An annular movable groove 13 is formed on the top of the mounting seat 10. A first annular edge 11 is provided on the outer wall, wherein one side of the first annular edge 11 is partially raised to form a protrusion 12. A first inverted L-shaped rod 14 is fixed to one side of the top of the base 1. A top block 15 is provided on the top of the rod. A second annular edge 16 is provided around the outer wall of the top block 15. One side of the second annular edge 16 is partially recessed to form a recess 17. A second inverted L-shaped rod 18 is vertically provided on one side of the top of the top block 15. A rotating shaft 19 is movably provided between the two. A pressure roller 110 is installed on the rotating shaft 19. The pressure roller 110 is directly above the recess 17 to provide auxiliary pressure for the material pressing process. The tablet compression assembly 4 is mounted above the mounting base 10: a mounting bracket 111 is fixed on the top of the mounting base 10, and a motor 40 is mounted in the center of its bottom. The transmission end of the motor 40 is connected to the turntable 41, providing rotational power to the turntable 41. Several support legs 44 are evenly distributed on the bottom of the turntable 41, and each support leg 44 is equipped with a caster 45 at its bottom end. The caster 45 fits against the inner bottom surface of the moving ring groove 13, so that the turntable 41 can rotate smoothly on the mounting base 10. Several loading slots 42 are opened on the surface of the turntable 41, and a lower mold lifting rod 43 is correspondingly set directly below each loading slot 42. The top rod 49 extends into the loading groove 42, and the bottom fixed tray 46 abuts against the first ring edge 11. The lifting and lowering of the top rod 49 is controlled by the protrusion 12 of the first ring edge 11. The top of the turntable 1 41 is vertically connected to the turntable 2 48 through the connecting rod 47. The upper mold pressure rod 410 is movably installed in the turntable 2 48 with the loading groove 42 as the reference. The pressure head 411 at the bottom of the upper mold pressure rod 410 is adapted to the shape of the loading groove 42. The pressure plate 412 at the top is always in contact with the upper surface of the second ring edge 16. The pressure head 411 is driven to press down the material by the recess 17 of the second ring edge 16. The anti-slip feeding assembly 3 is installed on the side of the mounting base 10, and the support rod 31 is fixed to the edge of the mounting base 10. The feeding slide 32 is installed upside down on its top. A baffle frame 33 is set at the top end of the feeding slide 32. The baffle frame 33 is precisely located above the protrusion 12 of the first ring edge 11 and is used to receive the tablets after demolding. The baffle frame 33 has two mounting openings 34 at its two corners. Mounting plate 1 35 and mounting plate 2 36 are fixed on the outside of the baffle frame 33 respectively. A rotating shaft 2 37 is installed on both mounting plates. A clamping wheel 312 is sleeved on the rotating shaft 2 37 and embedded in the mounting opening 34. A gear 38 is fixed at the top of the rotating shaft 37. The two gears 38 mesh with each other to ensure that the clamping wheels 312 rotate synchronously in opposite directions. A plate 39 is fixedly installed on one side of the baffle frame 33, on which a motor 310 is installed. The gear 311 at the transmission end of the motor 310 meshes with one of the gears 38 to provide power for the rotation of the clamping wheels 312. At the same time, the baffle frame 33 is set above the turntable 41, and the position of the loading groove 42 corresponds to the gap between the two clamping wheels 312, so that the demolded tablets can fall accurately between the clamping wheels 312, achieving stable feeding.

[0016] In actual use, after the equipment power is turned on, the motor 40 is powered on and runs. Its power output shaft drives the turntable 41 to rotate in a circular motion. When the evenly distributed loading grooves 42 on the surface of the turntable 41 move sequentially to the bottom of the packing assembly, the packing assembly starts to work, quantitatively loading the granular powder material into the loading grooves 42. While the turntable 41 rotates, it drives the turntable 48 to rotate synchronously. The top pressure plate 412 of the upper mold pressure rod 410 fixed on the turntable 48 is always in contact with the surface of the second ring edge 16. When the pressure plate 412 passes the second ring edge... When the recess 17 on the second ring edge 16 is reached, the surface height of the second ring edge 16 decreases, and the upper mold pressure rod 410 sinks vertically under the action of gravity and structure. The bottom pressure head 411 enters the loading groove 42. At the same time, with the cooperation of the pressure roller 110, the pressure head 411 and the push rod 49 cooperate to apply pressure to the granular powder material in the loading groove 42 and compact it into a sheet. When the pressure plate 412 rotates out of the recess 17 and returns to the normal height area, the upper mold pressure rod 410 resets upward under the action of the reset structure, and the pressure head 411 moves out of the loading groove 42. The turntable 41 rotates continuously, driving the lower mold lifting rod 43 mounted on it to rotate. The bottom tray 46 of the lower mold lifting rod 43 is attached to the surface of the first ring edge 11. When it rotates to the protrusion 12 on the first ring edge 11, the tray 46 is pushed by the protrusion 12, which drives the lower mold lifting rod 43 to lift upward, pushing the tablet after compression from the feeding groove 42. Because a baffle frame 33 is set directly above the protrusion 12, the tablet can be accurately placed between the two clamping rollers 312 after being pushed out. During the operation of the equipment, the motor 310 rotates continuously, and the gear 311 drives one of the gears 38 to rotate. The gear 38 meshes with the other gear 38, so that the two clamping rollers 312 rotate synchronously in opposite directions. Under the joint action of the two clamping rollers 312, the tablet located between them is pushed to the lower feeding slide 32, thereby completing the feeding operation.
