[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] This utility model provides two technical solutions:
[0023] Figure 1-Figure 4 The first embodiment is shown: a powder debris screening device for Chinese medicinal materials packaging, comprising a transmission frame 1, a transmission component 2 for conveying Chinese medicinal materials is provided on the inner side of the transmission frame 1, a dust suction component 3 for adsorbing dust is provided on the front side of the transmission frame 1, and a dust removal component 5 for blowing away dust is provided on the right side; the transmission component 2 comprises a conveyor belt 21 and a screening mesh belt 22, the conveyor belt 21 is installed on the inner side of the transmission frame 1 near the top through two transmission rollers, and the screening mesh belt 22 is installed on the inner side of the transmission frame 1 near the right side through two transmission rollers; the dust suction component 3 comprises a dust guard plate 31, the dust guard plate 31 is arranged on the inner side of the screening mesh belt 22, and the two sides of the dust guard plate 31 are fixed on the inner walls on both sides of the transmission frame 1.
[0024] A transmission pulley set 23 consisting of a synchronous wheel and a synchronous belt is installed between the transmission rollers of the conveyor belt 21 and the screening mesh belt 22. The transmission pulley set 23 is arranged on the outside of the transmission frame 1.
[0025] A mounting cover 4 is installed on the right side of the transmission frame 1, and a material leveling plate 41 is installed on the left side of the inner top of the mounting cover 4. The material leveling plate 41 is arranged above the conveyor belt 21. The material leveling plate 41 can be used to evenly spread the Chinese medicinal materials during the transportation process, so as to ensure that the Chinese medicinal materials are more uniform in subsequent screening and other processing processes, thereby improving the screening effect and overall work efficiency.
[0026] A brush plate 7 is installed on the outer surface of the transmission frame 1, and the brush on the brush plate 7 is in contact with the screening mesh belt 22. A dust collecting frame 71 is provided below the brush plate 7. A material guide seat 6 is fixedly installed at the bottom of the mounting cover 4. During the operation of the screening mesh belt 22, the brush plate 7 can clean the residual dust and impurities on the surface of the screening mesh belt 22. This can ensure the cleanliness of the surface of the screening mesh belt 22, avoid secondary contamination of dust and debris on the surface of the screening mesh belt 22, and further improve the screening effect. An dust collecting frame 71 is provided below the brush plate 7 to collect the cleaned dust and impurities, keeping the working environment clean. The screened Chinese medicinal materials can be guided through the material guide seat 6 so that they are discharged in an orderly manner, which is convenient for subsequent packaging and other operations.
[0027] Figure 1-Figure 4 The second embodiment is shown, and its main difference from the first embodiment is that the dust collection component 3 also includes a negative pressure fan 33, and a dust collection pipe 32 is installed at the input end of the negative pressure fan 33. The end of the dust collection pipe 32 passes through the outer wall of the transmission frame 1 and is connected to the dust shield 31. The output end of the negative pressure fan 33 is provided with a cyclone separator 34. The negative pressure fan 33 is started to generate negative pressure to adsorb dust and debris in the dust shield 31. This design can effectively collect dust and debris generated during the screening process, prevent it from spreading to the surrounding environment, and ensure the cleanliness of the working environment. At the same time, the setting of the cyclone separator 34 can separate and process the inhaled dust and debris, improving the dust collection effect and resource recycling rate.
[0028] The dust removal component 5 includes a positive pressure fan 51, and the air outlet of the positive pressure fan 51 is installed with an air outlet pipe 52. The end of the air outlet pipe 52 is installed with an air outlet cover 53. The air outlet cover 53 passes through the right surface of the installation cover 4 and extends inward. After the positive pressure fan 51 is started, air is sucked into the air outlet pipe 52 and blown out from the air outlet cover 53, which can blow away the falling Chinese medicinal materials, effectively remove dust and debris on the surface of the Chinese medicinal materials, improve the purity of the Chinese medicinal materials, and provide better conditions for subsequent packaging and other operations.
[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0030] During operation, the Chinese medicinal materials are placed on the conveyor belt 21, and the motor is started to convey the Chinese medicinal materials to the right. At the same time, the transmission pulley group 23 is cooperated to make the screening mesh belt 22 also run synchronously. During the transportation process of the Chinese medicinal materials, the Chinese medicinal materials can be evenly spread through the material-leveling plate 41, thereby ensuring the subsequent splitting effect of the Chinese medicinal materials. When the Chinese medicinal materials pass through the end of the conveying component 2 and fall down, the positive pressure fan 51 is started to suck air into the air outlet pipe 52 and blow it out from the air outlet hood 53, which can be used to blow away the falling Chinese medicinal materials, so that the dust on the surface of the Chinese medicinal materials is separated from the debris. Since the screening mesh belt 22 is set vertically, it is difficult for the Chinese medicinal materials to adhere to the screening mesh belt 22, thereby effectively preventing the Chinese medicinal materials from being stuck in the screening mesh. The pores of the belt 22 improve the screening effect, and the dust and debris pass through the pores on the screening mesh belt 22 and enter the dust shield 31. At the same time, the negative pressure fan 33 is started to generate negative pressure, which adsorbs the dust and debris in the dust shield 31 and discharges it through the discharge port of the cyclone separator 34. The screened Chinese medicinal materials fall onto the guide seat 6 and are discharged, thereby completing the dust and debris screening of the Chinese medicinal materials. During the operation of the screening mesh belt 22, the rough surface of the brush plate 7 is in contact with the screening mesh belt 22, so that the residual dust and impurities on the surface of the screening mesh belt 22 can be cleaned, ensuring the cleanliness of the surface of the screening mesh belt 22, avoiding secondary pollution of dust and debris on the surface of the screening mesh belt 22, and further improving the screening effect.
