Technical Field
[0001] The utility model belongs to the technical field of screening equipment, and particularly relates to a raw material screening instrument for the extraction of flavonoid active compounds. Background Art
[0002] Flavonoid active compounds are the most common phytochemicals, which help protect plants from cell damage caused by ultraviolet rays, fungal parasites, herbivores, pathogens, etc. When conducting extraction experiments on flavonoid active compounds, it is necessary to manually crush the raw materials and then screen them. Therefore, the following deficiencies exist:
[0003] 1. Currently, the crushing and screening of flavonoid active compound raw materials are carried out manually. The crushing and screening work often requires a lot of physical labor. Long-term manual operation will cause fatigue to workers, affecting the work quality and efficiency. At the same time, it is difficult to precisely control the particle size of crushing and screening manually, which may lead to uneven product particle size, thus affecting the subsequent extraction efficiency and product quality.
[0004] For this reason, we have proposed a raw material screening instrument for the extraction of flavonoid active compounds. Content of the Utility Model

At the same time, it is difficult to precisely control the particle size of crushing and screening manually, which may lead to uneven product particle size, thus affecting the subsequent extraction efficiency and product quality. And a raw material screening instrument for the extraction of flavonoid active compounds is proposed.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A raw material screening instrument for the extraction of flavonoid active compounds, comprising:
[0008] A screening box, the upper end of the screening box is fixedly connected with a crushing box, two crushing rollers are rotatably connected inside the crushing box, the rear ends of the two crushing rollers penetrate through the crushing box and are respectively fixedly connected with a driven gear and a driving gear, the driven gear and the driving gear are meshed for crushing raw materials, a first screening net is arranged at the upper end of the inner wall of the screening box, a second screening net is arranged in the middle of the inner wall of the screening box, and a screening plate is arranged at the lower end inside the screening box for screening raw materials of different specifications;
[0009] The guiding component, the guiding component includes a plurality of limiting frames fixedly installed on both sides of the inner wall of the screening box. The middle parts of the outer walls on both sides of the first screening net, the second screening net and the screening plate are fixedly connected with guiding rods. A spring is fixedly connected to the front end inside the limiting frame, and the guiding rod is slidably connected with the limiting frame;
[0010] The driving component, the driving component includes a servo motor fixedly installed on the outer wall of the rear end of the screening box. The output end of the servo motor is fixedly connected with a first connecting shaft. A small pulley is fixedly connected to the outer wall of the first connecting shaft. The rear end of the crushing roller penetrates through the crushing box and is fixedly connected with a large pulley. A belt is sleeved on the outer walls of the large pulley and the small pulley for driving the crushing roller to rotate.
[0011] In a possible design, an installation frame is fixedly connected to the upper part of the inner wall at the rear end of the screening box. The first connecting shaft penetrates through the installation frame and is fixedly connected with a first bevel gear. The lower end of the installation frame is rotatably connected with a second connecting shaft. The upper end of the second connecting shaft is fixedly connected with a second bevel gear inside the installation frame. The first bevel gear is meshed and connected with the second bevel gear. The lower end of the second connecting shaft is rotatably connected with the inner bottom surface of the screening box. Cam wheels are fixedly connected to the outer walls of the upper, middle and lower parts of the second connecting shaft. Limit blocks are fixedly connected to the rear ends of the first screening net, the second screening net and the screening plate. A second roller is rotatably connected inside the limit block.
[0012] In a possible design, the outer wall of the cam wheel is closely attached to the outer wall of the second roller for pushing the first screening net, the second screening net and the screening plate to move parallelly.
[0013] In a possible design, a plurality of sliding frames are fixedly connected to the front ends and rear ends of both sides of the inner wall of the screening box. First rollers are rotatably connected to both ends of the outer walls of both sides of the first screening net, the second screening net and the screening plate.

Since the rear ends of the shredding rollers are respectively fixedly connected with a driven gear and a driving gear, and the two are meshed, the two shredding rollers rotate towards each other to crush the raw materials. The crushed raw materials fall into the screening box and are first preliminarily screened through the first screening mesh. The raw materials with larger particles are retained on the first screening mesh, and the smaller particles fall through the mesh holes onto the second screening mesh for further screening. Finally, the fine particles that meet the specifications fall through the mesh holes of the second screening mesh onto the screening plate. At the same time, the servo motor also drives the second connecting shaft to rotate through the meshing transmission of the first bevel gear and the second bevel gear. The cam fixed on the second connecting shaft rotates accordingly, and its outer wall is in close contact with the second roller in the limiting block at the rear ends of the first screening mesh, the second screening mesh, and the screening plate, pushing the screening mesh and the screening plate to move parallelly, thereby accelerating the screening process and preventing blockage. The screened raw materials are respectively transported into the corresponding collection equipment through the discharge frames at the front ends of the first screening mesh, the second screening mesh, and the screening plate.
[0018] In this utility model, for the raw material screening instrument for extracting flavonoid active compounds, the automatic crushing and screening of raw materials are realized by driving through a servo motor, greatly reducing the manual labor intensity and improving the work efficiency. Through the setting of multiple screening meshes and screening plates, and through the setting of the cam, the screening mesh and the screening plate can perform moving screening, making the screening process more precise, ensuring the uniformity of the raw material particle size, and being beneficial to improving the subsequent extraction efficiency and product quality.
[0019] In this utility model, for the raw material screening instrument for extracting flavonoid active compounds, through the design of the guiding component and the sliding frame, the screening mesh and the screening plate are kept stable during the movement process, extending the service life of the equipment. At the same time, the design of the protective door and the handle at the front end of the screening box is convenient for opening, cleaning, and maintenance, and ensures the safety during the operation process.
