Description

Technical Field

[0001] This utility model belongs to the field of tablet press technology, and more specifically, it relates to a rotary tablet press. Background Technology

[0002] A pharmaceutical tablet press is a pharmaceutical equipment that compresses raw materials such as drug powders and granules into tablets of specific shapes, sizes, and hardness. It is widely used in the tablet production process of the pharmaceutical industry.

[0003] A lot of drug powder is generated during the flattening process. Existing devices are not good enough to recover the powder while pressing tablets, which makes them less practical. Existing devices cannot quickly adjust the pressing of tablets of different thicknesses through a simple structure. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rotary tablet press, which solves the problem that a lot of drug powder is generated during the flattening process, and that existing devices are insufficient to recover the powder while pressing tablets, resulting in low practicality; existing devices also cannot achieve rapid adjustment of tablet pressing thickness through a simple structure.

[0005] The purpose and effect of this rotary tablet press are achieved by the following specific technical means:

[0006] A rotary tablet press includes a main body; the main body has a concave structure; a receiving seat is fixed on the bottom surface of the inner wall of the main body, the bottom of the receiving seat has an inclined structure, and an air suction pipe is fixed on the receiving seat, the air suction pipe being connected to an external air suction fan through a pipe.

[0007] The suction pipe is a cylindrical tubular structure, and suction holes are arranged in a ring array on the outer wall of the suction pipe.

[0008] The main body is equipped with a pressing part, which consists of a rotating shaft, a seat, a pressing rod, a spring, a base plate, a pressing hole, a connecting arm, a baffle, a discharge hole, a first gear, a motor, and a second gear. A rotating shaft rotates on the main body, and a circular plate-shaped seat is welded on the rotating shaft. Pressing rods slide in a ring array on the seat. Each pressing rod has two retaining rings welded on it for the pressing rod to be at the upper limit of the seat. Each pressing rod is fitted with a spring for the pressing rod to return to its upward position. The lower end of the spring contacts the top surface of the seat, and the upper end of the spring contacts the retaining ring on the pressing rod.

[0009] The rotating shaft has a cylindrical plate-shaped base plate welded to one end. The base plate has pressure holes arranged in a ring array. The pressure holes are aligned with the pressure rods arranged in a ring array. A funnel is fixed on the main body, and the funnel is aligned with the rightmost pressure hole.

[0010] The main body has two connecting arms symmetrically welded to the top surface of its inner wall. The lower end of each connecting arm is welded to a baffle. The baffle is a circular plate structure. The top surface of the baffle is in contact with the bottom surface of the base plate. A discharge hole is provided on the left side of the top surface of the baffle, and the discharge hole is aligned with the receiving seat.

[0011] The rotating shaft is welded with a first gear, and a motor is fixed on the top surface of the main body. The motor is electrically connected to an external power supply, and a second gear is fixed on the output shaft of the motor. The second gear meshes with the first gear.

[0012] The main body has a concave mounting seat fixed on its top surface. A hydraulic cylinder is fixed on the top surface of the inner wall of the mounting seat. A cylindrical rod-shaped rotating seat is fixed to the extended end of the hydraulic cylinder. The rotating seat passes through the main body and a ball rotates on the rotating seat. When the shaft rotates, the upper end of the pressure rod comes into elastic contact with the ball. Under the pressure of the ball, the pressure rod is inserted into the pressure hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In terms of functionality, the motor-driven gear transmission rotates the shaft and related components, which, in conjunction with the hydraulic cylinder, rotating seat, and ball bearings, enables the pressure rod to precisely press down to complete the tableting action. The entire process is highly automated, ensuring the continuity and stability of the tableting action. Simultaneously, the corresponding arrangement of the funnel and pressure hole, and the discharge hole and receiving seat, allows the drug powder to enter the pressure hole in an orderly manner for compression and smoothly exit as finished tablets, resulting in a smooth and efficient process.

[0015] In terms of efficiency improvement, the ring-shaped array of pressure bars, pressure holes, and suction holes expands the range of tableting and suction, improves tableting efficiency and drug powder absorption, reduces production time, and enhances overall production efficiency.

[0016] In terms of resource utilization and environmental protection, the suction pipe and suction fan work together to absorb the drug powder at the receiving seat, facilitating reuse and effectively reducing drug powder waste. This lowers production costs and reduces waste generation, aligning with green production principles. Furthermore, the equipment's components are compact and work together seamlessly, with a scientifically sound overall design that ensures tableting quality while enhancing the equipment's practicality and reliability.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a rotary tablet press, including a main body 1; the main body 1 has a concave structure; a receiving seat 102 is fixed on the bottom surface of the inner wall of the main body 1, the bottom of the receiving seat 102 has an inclined structure, and an air suction pipe 3 is fixed on the receiving seat 102. The air suction pipe 3 is connected to an external air suction fan through a pipe. When in use, the external fan is started, and at this time the air suction pipe 3 can absorb the powder at the receiving seat 102, which is convenient for subsequent reuse.

[0028] The main body 1 is equipped with a pressing part 2, which consists of a rotating shaft 201, a seat 202, a pressing rod 203, a spring 204, a base plate 205, a pressing hole 206, a connecting arm 207, a baffle 208, a discharge hole 209, a first gear 210, a motor 211, and a second gear 212. A rotating shaft 201 rotates on the main body 1, and a circular plate-shaped seat 202 is welded on the rotating shaft 201. Pressing rods 203 slide in a ring array on the seat 202. Each pressing rod 203 has two retaining rings welded on it for the upper limit of the pressing rod 203 on the seat 202. Each pressing rod 203 is fitted with a spring 204 for the pressing rod 203 to return to its upward position. The lower end of the spring 204 contacts the top surface of the seat 202, and the upper end of the spring 204 contacts the retaining ring on the pressing rod 203.

[0029] Among them, a cylindrical plate-shaped base plate 205 is welded to one end of the rotating shaft 201. The base plate 205 has pressure holes 206 arranged in a ring array. The pressure holes 206 arranged in a ring array are aligned with the pressure rods 203 arranged in a ring array. A funnel 101 is fixed on the main body 1. The funnel 101 is aligned with the rightmost pressure hole 206.

[0030] Among them, two connecting arms 207 are symmetrically welded to the top surface of the inner wall of the main body 1. The lower end of each connecting arm 207 is welded to the baffle 208. The baffle 208 is a circular plate structure. The top surface of the baffle 208 is in contact with the bottom surface of the base plate 205. A discharge hole 209 is opened on the left side of the top surface of the baffle 208. The discharge hole 209 is aligned with the receiving seat 102.

[0031] Among them, a first gear 210 is welded on the rotating shaft 201, a motor 211 is fixed on the top surface of the main body 1, the motor 211 is electrically connected to an external power supply, and a second gear 212 is fixed on the output shaft of the motor 211, the second gear 212 meshes with the first gear 210.

[0032] The main body 1 has a concave mounting base 4 fixed to its top surface. A hydraulic cylinder 401 is fixed to the top surface of the inner wall of the mounting base 4. A cylindrical rod-shaped rotating seat 402 is fixed to the extended end of the hydraulic cylinder 401. The rotating seat 402 passes through the main body 1 and has a ball bearing 403 rotating on it. When the shaft 201 rotates, the upper end of the pressure rod 203 elastically contacts the ball bearing 403. Under the pressure of the ball bearing 403, the pressure rod 203 inserts into the pressure hole 206, placing the pill to be pressed into the funnel 101. The pill passes through the funnel 101 and enters the rightmost pressure hole 206, driving... When the motor 211 rotates, the shaft 201 rotates under the meshing of the second gear 212 and the first gear 210. The shaft 201 drives the seat 202, the pressure rod 203 and the base plate 205 to rotate. During the rotation of the shaft 201, the pills enter the subsequent pressing holes 206 in sequence. As the pressure rod 203 rotates, it moves downward through the squeezing action of the ball bearing 403 to complete the tableting action. The pressed medicine rotates until it moves to the discharge hole 209 and falls. The fallen tablets will enter the receiving seat 102 for discharge. When adjusting the tablet thickness, the hydraulic cylinder 401 can be extended or retracted.

[0033] Example 2: Based on Example 1, the suction tube 3 is a cylindrical tubular structure. The outer wall of the suction tube 3 is provided with suction holes 301 in an annular array. In use, the suction range of the suction tube 3 can be increased through the annular array of suction holes 301, which in turn improves the absorption effect of the drug powder.

[0034] Working principle: When in use, the pills to be compressed are placed into the funnel 101. The pills enter the rightmost pressing hole 206 through the funnel 101. The drive motor 211 rotates, and the shaft 201 rotates under the meshing of the second gear 212 and the first gear 210. The shaft 201 drives the seat 202, the pressing rod 203 and the base plate 205 to rotate. During the rotation of the shaft 201, the pills enter the subsequent pressing holes 206 in sequence. As the pressing rod 203 rotates, it moves downward through the squeezing action of the ball bearing 403 to complete the tableting action. The compressed medicine rotates until it moves to the discharge hole 209 and falls out. The fallen tablets will enter the receiving seat 102 for discharge. At the same time, the external fan is started, and the suction pipe 3 can absorb the powder at the receiving seat 102.
