Description

TECHNICAL FIELD

[0001] The utility model relates to the field of traditional Chinese medicine production equipment, specifically is the screening device of traditional Chinese medicine extract grinding. BACKGROUND

[0002] In the production process of traditional Chinese medicine, the effective components of traditional Chinese medicine need to be extracted by immersion equipment first, and then the extracted traditional Chinese medicine extract is concentrated and dried, and the dried traditional Chinese medicine extract needs to be classified and screened again. In the prior art, a classification and screening device is generally used for classifying and screening the traditional Chinese medicine extract, and the screening principle is that the traditional Chinese medicine extract passes through screens with different hole diameters, the large-particle extract is left on the screen, and the small-particle extract passes through the screen and falls on a screen with a smaller hole diameter for screening. Different particle sizes of traditional Chinese medicine extract can be screened out by using multiple screens.

[0003] The existing screening device is usually fixed on the rack at an inclined angle to improve the screening efficiency, and then the screen is vibrated by the vibration of the rack to realize the screening of the material. However, due to the inclined arrangement of the screen, the contact time between the material and the screen during screening is too short, which may cause part of the material to be discharged without participating in the screening, affecting the screening quality. In addition, the screen is fixed on the rack and is not convenient to take out for cleaning. The blockage of sundries in the screen hole will affect the subsequent screening. SUMMARY

[0004] Therefore, in order to solve the above problems, the utility model provides a screening device for traditional Chinese medicine extract grinding. The screening device is provided with a plurality of screening plates which are detachably connected and arranged in layers in the rack. The screening plates can be easily disassembled, cleaned or replaced, so that different mesh sizes of screening plates can be selected and installed, and the subsequent cleaning is also facilitated. In addition, the scraping mechanism arranged on the screening plate can scrape the sundries on the screening plate to one end, so as to avoid the accumulation of the sundries on the screening plate and affect the subsequent screening, thereby effectively ensuring the screening quality and efficiency.

[0005] The utility model is implemented as follows: a screening device for traditional Chinese medicine extract grinding is provided, which comprises a rack body, a vibration motor, a plurality of screening plates and a plurality of scraping mechanisms.

[0006] The plurality of screening plates are arranged in layers in the rack body and are detachably connected.

[0007] The vibration motor is arranged at the top of the rack body to drive the rack body and the internal screening plates to vibrate.

[0008] The plurality of scraping mechanisms are arranged above the plurality of screening plates to scrape the sundries on the surface of the screening plates to one end.

[0009] Preferably, the outer side of the frame body is provided with a fence, an opening is arranged on any one side of the frame body, a plurality of groove plates of different heights are symmetrically arranged on both sides of the opening end of the frame body, each groove plate is fixed to the frame body or the fence, and a mounting groove is formed on the opposite surface of the symmetrically distributed groove plates.

[0010] Preferably, the screening plate comprises a rectangular outer frame with an open end and a filter screen fixed in the outer frame, the outer frame is inserted into the mounting groove of the groove plate and arranged with the open end outward, an inclined surface is arranged above the open end of the outer frame, a fixing rod penetrating through the frame body or the fence is arranged on the outer side of the other end of the outer frame, and the screening plate is fixed by pressing the inclined surface of the outer frame against the end of the mounting groove through cooperation of the fixing rod and the nut.

[0011] Preferably, a material guide plate is further arranged above the groove plate and inclined to guide the material to the filter screen.

[0012] Preferably, each scraping mechanism comprises,

[0013] A plurality of transmission wheels are arranged above the screening plate in the frame body through two parallel rotating rods;

[0014] Two tension belts are arranged on the transmission wheels at the outer ends of the two rotating rods and kept parallel.

[0015] A scraper is fixed at one end to the two tension belts and provided at the other end with a soft brush for contacting the screening plate.

[0016] A driving motor is arranged outside the frame body to drive rotation of any one rotating rod.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] Firstly, the screening plate in the screening device is movably installed, which greatly simplifies the maintenance process of the equipment. In actual use, when the screening plate is blocked or damaged, the staff can quickly disassemble it from the frame body for cleaning or replacement, and different mesh screening plates can be conveniently selected and installed, so that the screening device can flexibly cope with the screening requirements of various materials.

[0019] Secondly, by setting the scraping mechanism on the screening plate, it can ensure that the scraping mechanism continuously scrapes the impurities screened out on the screening plate to one end during the screening process, effectively avoiding the accumulation of impurities on the screening plate. Because the accumulation of impurities often hinders the normal screening of the material, causing part of the material to be unable to pass through the screen, reducing the screening efficiency and quality. The presence of the scraping mechanism ensures that the screening plate is always in good working condition, and the material can smoothly pass through the screen, thereby significantly improving the screening efficiency and ensuring the stability of the screening quality. Finally, through the automatic operation of the scraping mechanism, the frequency of manual cleaning of the impurities on the screening plate is reduced. It is conducive to realizing automatic processing. BRIEF DESCRIPTION OF DRAWINGS
