Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a western medicine tablet press. Background Art

[0002] Medicines are important substances to protect people's health. In order to play a good role in the efficacy of medicines, medicines will be made into tablets, granules or capsules according to their usage and the time required for the efficacy. Among them, the use of Western medicine tablets is particularly extensive. Western medicine tablets can be swallowed, taken orally, etc., which are convenient to use. Western medicine tablets are divided into plain tablets and coated tablets. Plain tablets are made by using a tablet press to directly press the drug particles into a certain dosage, and then the formed tablets are packaged without further processing. Coated tablets are made by evenly coating the outer surface of the plain tablets with other substances to protect or isolate the plain tablets and prevent the plain tablets from contacting with foreign objects. The tablets pressed by the tablet press will be attached with more drug dust and tiny particles on the outer surface due to the limitations of its process equipment. These drug dust and tiny particles will fall off randomly during the packaging or coating process, directly affecting the tightness of the packaging and the uniformity and consistency of the coating. It can be seen that the drug dust and tiny particles attached to the outer surface of the western medicine tablets directly affect the quality of the western medicine tablets. Therefore, a western medicine tablet press that can remove the drug dust and tiny particles attached to the outer surface of the western medicine tablets is needed. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is clearly and completely described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4A tablet press for western medicine shown in the figure includes a feeding mechanism 1, a tablet pressing mechanism 2 and a tablet collecting and dust removing mechanism 3. The feeding mechanism 1 and the tablet collecting and dust removing mechanism 3 are respectively arranged at the two ends of the tablet pressing mechanism 2. The feeding mechanism 1 conveys the drug raw material particles to the tablet pressing mechanism 2. The tablet pressing mechanism 2 presses the drug raw materials into drug tablets through pressing components and drug molds. A lot of raw material dust and tiny particles will adhere to the surface of the drug tablets after demolding, and they need to be conveyed to the tablet collecting and dust removing mechanism 3 to remove the dust and particles on the outer surface. The tablet collecting and dust removing mechanism 3 includes a fixed cylinder 3-1, a vibrating cylinder 3-2 and a tablet collecting barrel 3-3. The fixed cylinder 3-1 is supported on the side of the tablet pressing mechanism 2. The drug tablets after demolding are pushed into the fixed cylinder 3-1, as shown in FIG. Figure 4 As shown, the fixed cylinder 3-1 includes a tablet channel 3-1-1 and a powder channel 3-1-2, an inclined grading plate 3-1-3 is arranged between the tablet channel 3-1-1 and the powder channel 3-1-2, the powder channel 3-1-2 is fixedly arranged below the grading plate 3-1-3, and a plurality of through holes connecting the tablet channel 3-1-1 and the powder channel 3-1-2 are arranged in an array on the grading plate 3-1-3. The tablets pressed by the tablet pressing mechanism 2 are pushed and slid into the tablet channel 3-1-1. During the sliding process along the grading plate 3-1-3, the dust and tiny particles adhered to the tablets fall into the powder channel 3-1-2 through the through holes on the grading plate 3-1-3. The tablets complete the primary cleaning, and the tablets slide into the vibration cylinder 3-2. The lower end of the vibration cylinder 3-2 is inclined. The vibration cylinder 3-2 includes an outer cylinder 3-2-1, an inner cylinder 3-2-2 and a vibrator 3-2 -3, the outer cylinder 3-2-1 is sleeved on the outside of the inner cylinder 3-2-2 and is movably connected with the inner cylinder 3-2-2, the vibrator 3-2-3 is fixedly arranged on the inner cylinder 3-2-2 and can drive the inner cylinder 3-2-2 to vibrate, and a shock absorber is arranged between the outer cylinder 3-2-1 and the inner cylinder 3-2-2; the outer cylinder 3-2-1 includes a dust collecting cylinder 3-2-1a and a dust suction pipe 3-2-1b, the dust suction pipe 3-2-1b is arranged at the bottom of the end of the dust collecting cylinder 3-2-1a, and the dust suction pipe 3-2-1b is connected with the vacuum hose 3-5; the inner cylinder 3-2-2 is provided with a plurality of through holes penetrating the cylinder wall, and the through holes connect the inner cavity of the inner cylinder 3-2-2 with the outer cylinder 3-2-1, the lower end of the inner cylinder 3-2-2 is for tablet outlet, and the tablet collecting barrel 3-3 is arranged below the tablet outlet of the inner cylinder 3-2-2, and the fixed cylinder 3-1 and the vibrating cylinder 3-2 are connected through a flexible connecting pipe 3-4.

[0024] like Figure 4As shown, the tablet passage 3-1-1 of the fixed cylinder 3-1 is also provided with an arc-shaped shield 3-1-4 that is movably connected. The arc-shaped shield 3-1-4 is mounted on the tablet passage 3-1-1. The arc-shaped shield 3-1-4 can guide the gas entering the fixed cylinder 3-1 and prevent the tablets from colliding and sliding to the outside. The outer side of the arc-shaped shield 3-1-4 is provided with an elastic card 3-1-4a that is compatible with the tablet passage 3-1-1. A plurality of elastic cards 3-1-4a are sleeved on the outside of the tablet passage 3-1-1. The elastic card 3-1-4a structure facilitates the rapid disassembly and assembly of the arc-shaped shield 3-1-4. The flexible connecting tube 3-4 is made of elastic material, preferably a silicone hose, which is convenient for rapid disassembly and assembly.

[0025] Two buffer plates 3-3-1 are arranged facing each other in the tablet collecting barrel 3-3. The buffer plates 3-3-1 are arranged obliquely, and a support spring 3-3-2 is arranged between the bottom surface and the tablet collecting barrel 3-3. One end of the buffer plate 3-3-1 is hinged on the inner wall of the tablet collecting barrel 3-3, and the other free end is staggered and overlapped in the middle of the tablet collecting barrel 3-3. The pharmaceutical tablets fall into the tablet collecting barrel 3-3, accumulate on the buffer plate 3-3-1, and gradually press the buffer plate 3-3-1 down until the inclination angle of the buffer plate 3-3-1 increases to allow the pharmaceutical tablets to slide into the tablet collecting barrel 3-3. The support spring 3-3-2 resets the buffer plate 3-3-1. The buffer plate 3-3-1 is made of a silicone plate or a polytetrafluoroethylene plate. The buffer plate 3-3-1 can reduce the impact on the slipping pharmaceutical tablets and ensure their integrity.
