Technical Field

[0001] The utility model relates to the technical field of powder product screening, in particular to the fine sieve structure of a plant powder extraction device. Background Art

[0002] In the existing plant powder extraction technology, traditional screening equipment usually adopts static or inefficient vibration methods, which lead to the following problems: First, the screening efficiency is low and cannot meet the needs of large-scale production. Especially when dealing with highly viscous or easily agglomerated plant powders, it is easy to cause screen blockage and reduce the screening speed; Second, it is difficult to control the screening accuracy. For applications that require strict particle size grading, traditional equipment often fails to meet the required standards. Therefore, we propose the fine sieve structure of a plant powder extraction device. Summary of the Utility Model

[0030] In this embodiment, the screening component 4 includes a screening frame 41, and two rocking members 42 are provided at the front and rear ends of the screening frame 41. The two rocking members 42 located on the same side are respectively slidably installed in the slide grooves 3 on the left and right sides. A transmission wheel 43 is provided at one end of the screening frame 41 close to the driving component 5, and a bottom plate 44 is detachably installed at the lower end of the screening frame 41; a plurality of screening holes 441 are evenly provided at the upper end of the bottom plate 44, and three card slots 442 are evenly spaced on the left and right sides of the upper end of the bottom plate 44; three card columns 411 used in conjunction with the card slots 442 are fixedly installed on the left and right sides of the lower end of the screening hole 441, and the card slots 442 are sleeved on the screening hole 441 to fix the bottom plate 44 to the lower end of the screening frame 41.

[0031] Through the above scheme: due to the asymmetric shape of the eccentric wheel 53, it will apply a periodic thrust to the transmission wheel 43 in contact with it during rotation, thereby causing the screening frame 41 to vibrate. At this time, the slider 422 on the rocking member 42 slides back and forth in the slide groove 3, and the elastic action of the spring 423 enables the screening frame 41 to vibrate stably and regularly, thereby effectively improving the screening efficiency, reducing material blockage, and ensuring continuous screening.

[0032] In this embodiment, the rocking member 42 includes a connecting rod 421, one end of which is fixedly connected to the screening frame 41, and a slider 422 is fixedly installed on the other end of the connecting rod 421, and the slider 422 is slidably connected to the slide groove 3, and the left and right ends of the slider 422 are fixedly connected with springs 423, and the ends of the two springs 423 away from the slider 422 are respectively fixedly connected to the left and right inner walls of the slide groove 3; the driving component 5 includes a driving motor 51, the driving motor 51 is fixedly installed in the stand 2, and a rotating rod 52 is fixedly installed on the output end of the driving motor 51, and the rotating rod 52 is movably installed in the stand 2, and an eccentric wheel 53 is fixedly installed on the rotating rod 52; the position of the eccentric wheel 53 corresponds to the position of the transmission wheel 43, and the outer surface of the eccentric wheel 53 is in contact with the outer surface of the transmission wheel 43.

[0033] Through the above solution, the bottom plate 44 with different sieve hole 441 sizes can be set according to actual screening requirements. The bottom plate 44 adopts a detachable connection method of a card slot 442 and a card post 411, realizing the flexible disassembly and assembly of the bottom plate 44, so that the screening accuracy can be flexibly adjusted to meet the requirements of various materials.

[0034] It should be noted that the present utility model is a fine sieve structure of a plant powder extraction device. The bottom plate 44 with different sieve hole 441 sizes can be set according to actual screening requirements. During use, the driving motor 51 is started, and the driving motor 51 starts to operate, driving the rotating rod 52 fixed to its output shaft to rotate. As the rotating rod 52 rotates, the eccentric wheel 53 fixed on it also rotates synchronously. Due to the asymmetric shape of the eccentric wheel 53, it will exert a periodic thrust on the transmission wheel 43 in contact with it during rotation, thereby causing the vibration of the screening frame 41. The vibration of the screening frame 41 is transmitted to the entire screening assembly 4 through the shaking member 42. The slider 422 on the shaking member 42 slides back and forth in the chute 3, and the elastic action of the spring 423 enables the screening frame 41 to vibrate stably and regularly. This vibration prompts the plant powder to be screened through the sieve holes 441 on the bottom plate 44. The screened fine particles fall into the collection box 7 below, and the collection box 7 can be easily moved through the slide rail 6 to facilitate the collection and processing of materials. At the same time, the bottom plate 44 adopts a detachable connection method of a card slot 442 and a card post 411, realizing the flexible disassembly and assembly of the bottom plate 44, so that the screening accuracy can be flexibly adjusted to meet the requirements of various materials.
