[0002] Chinese herbal medicine production refers to the use of Chinese herbal medicine raw materials and processing them into products that meet pharmaceutical standards through a series of systematic process flows. Chinese herbal medicine occupies an important position in traditional Chinese medicine and is widely used in clinical and scientific research fields. In order to ensure the quality and safety of Chinese herbal medicine, the production process requires careful control of the cleaning, drying and screening links.

[0003] The screening of Chinese herbal medicines mainly relies on production workers to operate with handheld sieves. This traditional screening method guarantees the quality and purity of Chinese herbal medicines to a certain extent, but it has some shortcomings in actual use. First, manual screening is inefficient and the production cycle is long. Due to the wide variety and different materials of Chinese herbal medicines, workers not only consume a lot of manpower and material resources when screening, but may also cause misscreening or omissions, thus affecting the quality of the final product. Secondly, manual screening is difficult to standardize and automate. With the continuous improvement of modern production requirements, traditional manual screening methods can no longer meet the needs of large-scale production. In order to solve these problems, we proposed a multi-stage screening device for Chinese herbal medicines. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1-4 The sieve 3 that is provided with is provided with the sieve box 3 of the present invention, and the sieve box 3 of the present invention is provided with a sieve box 3 of the present invention.

[0022] When screening Chinese herbal medicines, the Chinese herbal medicines to be screened are first introduced into the feed hopper 2, and then, according to actual feeding needs, the displacement component is used to drive the material blocking plate 6 to slide in the slide 9, so that the Chinese herbal medicines can pass through the device frame 1 and fall into the interior of the screening box 3. At the same time, the vibration component is used to drive the screening box 3 to move, and the four connecting rods 8 generate vibration, which makes the Chinese herbal medicines entering the screening box 3 move between the primary screen 10 and the secondary screen 11, and complete the screening work under the action of these two screens. The primary screen 10 can screen out large pieces of herbs or branches and leaves in the Chinese herbal medicines, while the secondary screen 11 guides qualified Chinese herbal medicines out of the discharge slot 20. At the same time, small pieces of herbs or dust will pass through the secondary screen 11 and be discharged from the side discharge ports 21 on both sides of the screening box 3 under the action of the discharge plate 12 and the guide block 19. Through this device, the multi-stage screening of Chinese herbal medicines can be conveniently completed, while reducing manual intervention and improving the efficiency of Chinese herbal medicine production.

[0023] like Figures 1-4 As shown, the vibration assembly includes a mounting plate 13, which is fixedly connected to the outside of the device frame 1, and a round box 15 is fixedly connected to the bottom of the mounting plate 13 and located on the outside of the device frame 1. The internal rotation of the round box 15 is connected to a cam 16, and a silent pad 17 is fixedly connected to one side of the screening box 3. One end of the cam 16 is in contact with the silent pad 17. A power motor 14 is fixedly installed on the top of the mounting plate 13, and the output end of the power motor 14 passes through the mounting plate 13 and is fixedly connected to the cam 16. Elastic pads 18 are fixedly connected to both sides of the silent pad 17 and located on the outside of the screening box 3.

[0024] The cam 16 is driven by the power motor 14 to rotate inside the round box 15. The cam 16 rotates and contacts the silent pad 17 on one side of the screening box 3. Through continuous contact, the screening box 3 moves inside the device frame 1 and vibrates, thereby facilitating the cooperation with the primary screen 10 and the secondary screen 11 to complete the screening of Chinese herbal medicines.

[0025] like Figures 1-4 As shown, the displacement assembly includes a fixed plate 4, which is fixedly connected to the top of the device frame 1, and a threaded rod 5 is rotatably connected between the fixed plate 4 and the feed hopper 2. The outer side of the threaded rod 5 is threadedly connected to the material blocking plate 6, and a servo motor 7 is fixedly installed on one side of the fixed plate 4. The output end of the servo motor 7 passes through the fixed plate 4 and is fixedly connected to the threaded rod 5.

[0026] The threaded rod 5 is driven by the servo motor 7 to rotate between the fixed plate 4 and the feed hopper 2, so that the material blocking plate 6 moves under the action of the threaded rod 5, so that the material blocking plate 6 can complete the feeding of Chinese herbal medicines according to usage requirements.

[0027] The utility model provides a multi-stage screening device for Chinese herbal medicines. The specific working principle is as follows: when screening Chinese herbal medicines, the Chinese herbal medicines to be screened are first introduced into the feed hopper 2, and then according to the actual feeding needs, the servo motor 7 is used to drive the threaded rod 5 to rotate between the fixed plate 4 and the feed hopper 2, so that the material blocking plate 6 moves under the action of the threaded rod 5, so that the Chinese herbal medicines can pass through the device frame 1 and fall into the interior of the screening box 3. At the same time, the power motor 14 is used to drive the cam 16 to rotate inside the round box 15, so that the cam 16 rotates continuously and is aligned with the side of the screening box 3. The silent pad 17 contacts, thereby generating a collision, further prompting the screening box 3 to vibrate under the action of the four connecting rods 8, which makes the Chinese herbal medicines entering the screening box 3 move between the primary screen 10 and the secondary screen 11, and complete the screening work under the action of these two screens. The primary screen 10 can screen out large pieces of herbs or branches and leaves in the Chinese herbal medicines, while the secondary screen 11 guides the qualified Chinese herbal medicines out of the discharge slot 20. At the same time, small pieces of herbs or dust will pass through the secondary screen 11 and be discharged from the side discharge ports 21 on both sides of the screening box 3 under the action of the discharge plate 12 and the guide block 19.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
