Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a screening machine for particles of a traditional Chinese medicine preparation. Background Art

[0002] Chinese herbal formula granules are granules made from Chinese herbal medicine slices that meet the processing standards through modern pharmaceutical technologies such as water extraction, concentration, drying, and granulation. During the processing, the granules after granulation are graded by a screening machine to separate particles of different particle sizes to meet the needs of different dosage forms and ensure the purity of the raw materials and the consistency of the particles.

[0003] The existing screening machine uses a sieve plate as a screening structure. The sieve plate is driven to vibrate at a high frequency by vibration. The Chinese medicine preparation particles fall on the sieve plate and pass through the sieve holes to complete the screening. When screening the feed, a large amount of Chinese medicine preparation particles are usually poured in at one time. After the sieve plate has frequently and continuously screened the Chinese medicine preparation particles, some of the Chinese medicine preparation particles will usually be stuck in its sieve holes, causing the sieve holes to be blocked and the sieve plate to fail, which will eventually affect the working efficiency of the screening machine.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1 - Figure 8 The illustrated machine for screening particles of traditional Chinese medicine preparations comprises a box body 4, a vibration motor 10 being fixed to the bottom of the box body 4, a top plate 3 being provided on the top of the box body 4, and a feed hopper 2 being fixed to the top of the top plate 3, two sieve plates 51 being provided inside the box body 4, and a support plate 52 being provided below the bottommost sieve plate 51, a discharge funnel 5 being provided on one side of the box body 4 near the ends of the sieve plate 51 and the support plate 52, through holes 9 being provided on both side walls of the box body 4, a material clearing assembly being inserted into the through holes 9, the material clearing assembly comprising a mounting plate 1, and an insertion rod 102 being provided at the bottom of the mounting plate 1;

[0028] In this embodiment, specifically, there are two groups of through holes 9, each group of through holes 9 consists of two rectangular holes, the length of each through hole 9 is the same as the length of the mounting plate 1, the height of the through hole 9 is greater than the sum of the thickness of the mounting plate 1 and the length of the insertion rod 102, each group of through holes 9 corresponds to a sieve plate 51, and the height of the through holes 9 in this group is higher than the height of the sieve plate 51. After the mounting plate 1 is inserted into the through hole 9 and passes through the box body 4, the insertion rod 102 at the bottom of the mounting plate 1 corresponds to the sieve hole of the sieve plate 51;

[0029] Specifically, in the process of screening the Chinese medicine preparation particles, the vibration motor 10 is started, the vibration motor 10 generates vibration and transmits it to the box body 4, the sieve plate 51 in the box body 4 shakes, and the Chinese medicine preparation particles are poured into the feed hopper 2. The Chinese medicine preparation particles pass through the feed hopper 2 and enter the box body 4, and fall on the sieve plate 51 inside the box body 4. Under the action of vibration, the Chinese medicine preparation particles pass through the sieve holes of the sieve plate 51. The Chinese medicine preparation particles pass through two sieve plates 51, and the size of the sieve holes on the two sieve plates 51 decreases from top to bottom, so that particles of different sizes can be screened. The screened particles are finally discharged from the discharge funnel 5. A conveyor belt can be installed at the end of the discharge funnel 5 to transport the Chinese medicine preparation particles to the packaging bag.

[0030] like Figure 1 - Figure 7 As shown, a first pushing mechanism 41 is provided on the top of the top plate 3, and a second pushing mechanism 42 is provided on the front and rear surfaces of the box body 4. The first pushing mechanism 41 and the second pushing mechanism 42 are both used to push the mounting plate 1 downward;

[0031] The first pushing mechanism 41 and the second pushing mechanism 42 both include a fixed block 411, an electric push rod 412 is fixed on the fixed block 411, a pressure block 413 is fixed to the telescopic end of the electric push rod 412, a slide groove is provided at the bottom of the pressure block 413, a slide rod 414 is inserted into the slide groove, the fixed block 411 of the first pushing mechanism 41 is fixed to the top of the top plate 3, and the fixed block 411 of the second pushing mechanism 42 is fixed to the outer wall of the box body 4; specifically, after the mounting plate 1 passes through the through hole 9 and the box body 4, the electric push rod 412 of the first pushing mechanism 41 pushes the mounting plate 1 downward, so that the convex strip 101 at the bottom of the mounting plate 1 is inserted into the sieve hole, thereby cleaning out the particles in the sieve hole.

[0032] like Figure 1 - Figure 6 As shown, a guide rail 13 is provided on the side of the side wall of the box body 4 close to the through hole 9, a guide groove 131 is provided at the bottom of the guide rail 13, and a convex strip 101 is provided on the top of the mounting plate 1, and the convex strip 101 can be matched with the guide groove 131; specifically, in the process of inserting the mounting plate 1 into the through hole 9, the convex strip 101 can be matched with the guide groove 131 so that the top and both ends of the mounting plate 1 can be adapted to the through hole 9, avoiding the box body 4 blocking the two ends, top and bottom of the mounting plate 1, which is conducive to smoother insertion of the mounting plate 1 and more convenient during manual operation.

[0033] like Figure 1 - Figure 6As shown, a spring support 7 is also provided at the bottom of the box body 4, and a support frame 6 is fixed to the bottom of the spring support 7; specifically, when the vibration motor 10 is in working state, the vibration generated is transmitted to the spring support 7 through the box body 4, and the spring support 7 vibrates after being vibrated, thereby driving the entire box body 4 to vibrate at high frequency, which is conducive to the Chinese medicine preparation particles passing through the sieve plate and completing the screening.

[0034] like Figure 1 - Figure 6 As shown, a first baffle 8 is inserted into the through hole 9 on one side of the box body 4, and a second baffle 11 is inserted into the through hole 9 on the other side, and a limiting plate 12 is fixed to one side of the second baffle 11; specifically, the first baffle 8 and the second baffle 11 are used to block the through hole 9 to ensure that the traditional Chinese medicine preparation particles falling into the box body 4 will not be discharged through the through hole 9.

[0035] like Figure 6 As shown, a limiting bracket 14 is fixed to one side of the box body 4, and the limiting bracket 14 is an L-shaped structure; specifically, after one end of the mounting plate 1 is inserted from the through hole 9 on one side of the box body 4 and passes through the through hole 9 on the other side, the end of the mounting plate 1 will push the second baffle 11 away from the through hole 9 and push the limiting plate 12 at the same time. The limiting plate 12 continues to move until it contacts the limiting bracket 14, thereby ensuring that the mounting plate 1 can reach the correct position. At this time, the insertion rod 102 at the bottom of the mounting plate 1 is aligned with the sieve hole on the sieve plate 51. During the downward process of the mounting plate 1, the insertion rod 102 can pass through the sieve hole, thereby pushing out the particles remaining in the sieve hole, cleaning out impurities, and keeping the sieve hole unobstructed.

[0036] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
