Description

Technical Field

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

[0002] A tablet press machine is a machine that can press powdery or granular drugs into tablet-shaped drugs. The thickness of the tablets can be adjusted by itself, and both thin and thick tablets can be produced.

[0003] During the continuous production of tablets by a tablet press machine, it is inevitable that the tablets will adhere to powdery or granular drugs. Due to the relatively fast production speed, the stamped tablets are often transferred to a screening machine through a conveyor for vibrating screening to complete the separation of the tablets and the drugs and obtain the finished tablets. In the traditional method, a large number of devices are set up and a large amount of space is occupied.

[0004] Therefore, a tablet press machine is proposed. Utility Model Content

[0005] The purpose of the present utility model is to address the above-mentioned problems and propose a tablet press machine that can reduce the number of devices and space occupation.

[0006] A tablet press machine includes a press machine main body.

[0023] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings. However, this embodiment does not limit the protection scope of the present invention. Structural, method, or functional transformations made by those of ordinary skill in the art based on this embodiment are all included in the protection scope of the present invention.

[0024] The present invention discloses a tablet press, as Figure 1 , Figure 2 and Figure 3 shown, including a tablet press main body 11. A three-way material distributor 1, a vibrator 8, and a three-way aggregate pipe 9 are fixedly installed on the side wall of the tablet press main body 11 in sequence from top to bottom. The tablet press main body 11 is an existing device capable of completing processes such as feeding, tablet pressing, and discharging. The three-way material distributor 1 is an existing device capable of feeding at one end and discharging at both ends respectively. The vibrator 8 is an existing device that can generate vibration.

[0025] A pair of conveyor cylinders 2 are fixedly installed on the upper side of the vibrator 8 through support arms. The upper end of the three-way material distributor 1 is connected and assembled with the discharge port of the tablet press main body 11. The other two ends of the three-way material distributor 1 are respectively connected and assembled with the upper ends of the conveyor cylinders 2 through flexible pipes 10. The lower ends of the conveyor cylinders 2 are respectively connected and assembled with the three-way aggregate pipe 9 through flexible pipes 10. The vibrator 8 is used to generate vibration on the conveyor cylinders 2. Due to the presence of flexible pipes 10 (such as pipes made of rubber material), vibration transmission to the three-way material distributor 1 and the three-way aggregate pipe 9 can be avoided.

[0026] A screening cylinder 4 is rotatably installed inside the conveyor cylinder 2. A driving component 6 is installed on the side wall of the tablet press main body 11. A transmission component 5 is installed between the driving component 6 and the screening cylinder 4. The driving component 6 can drive the rotation of the two screening cylinders 4 simultaneously through the transmission of the transmission component 5. After the tablets are produced, they enter the three-way material distributor 1 through the discharge port for distribution, and then are screened by the rotating screening cylinder 4 and discharged.

[0027] Specifically, as Figure 3As shown, the screening cylinder 4 includes a screen tube 41 and a discharge pipe 42 fixedly installed together. The screen tube 41 is trumpet-shaped, and the dimension of the end close to the three-way distributor 1 is larger than that of the end far from the three-way distributor 1. The screening cylinder 4 with such a shape is conducive to the entry of tablets and the reduction of the discharge speed, increases the residence time of the tablets in the screening cylinder 4, and is conducive to the separation of tablets from powders or granular drugs.

[0028] Furthermore, the circumferential sides of both the screen tube 41 and the discharge pipe 42 are rotationally assembled with the conveying cylinder 2 through bearings. A support block 3 is fixedly installed between the outer ring of the bearing on the screen tube 41 and the conveying cylinder 2, and the support blocks 3 are evenly distributed in a circumferential manner. The bearings can reduce the rotational resistance of the screening cylinder 4, and the distributed support blocks 3 will not affect the downward convergence and discharge of powders or granular drugs along the conveying cylinder 2.

[0029] Specifically, as Figure 4 shown, the drive assembly 6 includes a driving bevel gear 61, a driven bevel gear 62, a motor 63, and a U-shaped seat 64. The side wall of the tablet press main body 11 is fixedly installed with the U-shaped seat 64. The lower end of the three-way collecting pipe 9 passes through the U-shaped seat 64, and the U-shaped seat 64 plays a supporting role to avoid affecting the setting of the three-way collecting pipe 9. A motor 63 is fixedly installed on the side wall of the U-shaped seat 64, the output end of the motor 63 is fixedly installed with the driving bevel gear 61, and a pair of driven bevel gears 62 are rotationally installed on the side wall of the U-shaped seat 64 through bearing seats. The driving bevel gear 61 is meshed and assembled between the driven bevel gears 62. The motor 63 can rotate the driving bevel gear 61 and simultaneously rotate the driven bevel gears 62 on both sides through the meshing relationship. The application of bevel gears allows the transmission assembly 5 to be inclined, so as to match the inclination angle of the screening cylinder 4 and ensure the smooth transmission of power.

[0030] Specifically, the transmission assembly 5 includes a driven pulley 51, a belt 52, and a driving pulley 53. The driving pulley 53 is fixedly installed on the shaft of the driven bevel gear 62, the driven pulley 51 is fixedly installed on the circumferential side of the discharge pipe 42, and the driven pulley 51 and the driving pulley 53 are sleeved with the belt 52. The driving pulley 53 rotates synchronously with the driven bevel gear 62, and the screening cylinder 4 is rotated through the belt 52 and the driven pulley 51. The transmission mode of the belt has a certain flexibility and can still complete the power transmission when there is vibration on the screening cylinder 4.

[0031] Specifically, a protective cover 12 is fixedly installed on the side wall of the tablet press main body 11, and the protective cover 12 is provided with through holes for passing through the discharge pipe 42 and the lower end of the three-way collecting pipe 9. The protective cover 12 can isolate and protect structures such as the three-way distributor 1, the conveying cylinder 2, the vibrator 8, the three-way collecting pipe 9, the transmission assembly 5, and the drive assembly 6, and avoid interference from the external environment or foreign objects.

[0032] Furthermore, a sealing ring 13 is fixedly installed between the outlet pipe 42 and the through hole. The sealing ring 13 can be made of rubber material. While there is vibration in the outlet pipe 42, it can always fill the gap between the outlet pipe 42 and the through hole, ensuring the isolation effect of the protective cover 12.

[0033] Specifically, a feeding pipe 7 is connected and installed at the top feeding port of the tablet press main body 11. The feeding pipe 7 is used to continuously transport the powder or granular medicine in the external storage hopper into the tablet press main body 11 for use.

[0034] Furthermore, a screw conveyor can be installed on the side wall of the tablet press main body 11. One end of the screw conveyor is connected to the lower end of the three-way aggregate pipe 9, and the other end of the screw conveyor is connected and assembled with the storage hopper, so that the recycled powder or granular medicine can be directly reused.

[0035] The above electrical equipment is electrically connected to the distribution box of the tablet press main body 11 and is uniformly set and controlled through the control panel.

[0036] The working mode of this embodiment:

[0037] The powder or granular medicine fed through the feeding pipe 7 is continuously tableted by the tablet press main body 11 and then discharged from the discharge port into the three-way distributor 1. The three-way distributor 1 periodically swings the dial to switch the conveying direction of the tablets, so that the tablets are distributed into the two screening cylinders 4 to meet the production speed and screening time;

[0038] At the same time, the vibrator 8 can vibrate the conveying cylinder 2 and the screening cylinder 4, and the driving assembly 6 can synchronously rotate the screening cylinder 4 through the transmission assembly 5. Due to the effects of vibration, tablet rolling and centrifugation, the powder or granular medicine on the tablets will pass through the screen pipe 41 into the conveying cylinder 2, and be concentrated and discharged along the three-way aggregate pipe 9, recycled through the provided sealed recycling box, or directly sent back to the storage hopper through the provided screw conveyor. The screened tablets are discharged through the outlet pipe 42 and then stored in the provided sealed storage box.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
