For the return of standard raw materials, the screening mechanism 6 includes a screening frame 601, and two groups of symmetrically distributed sliders 602 are provided on both sides of the screening frame 601. The screening mechanism 6 is set to screen the medicinal raw materials crushed by the two groups of crushing rollers 3. The raw materials that meet the composite screening standards fall out of the installation box 1 after passing through the screening frame 601, while the raw materials that do not meet the screening standards continue to remain on the screening frame 601. The raw materials that do not meet the screening standards are returned to the top of the two groups of crushing rollers 3 by the action of the scraper 707 in the returning mechanism 7, and are re-crushed and discharged until they meet the composite screening standards and pass through the bottom of the installation box 1 for discharge.

[0026] In this embodiment, reference Figure 4As shown, two groups of symmetrically distributed installation rods 603 are provided in the installation box 1, the slider 602 is slidably sleeved with the installation rod 603, and a telescopic spring 604 is provided on the installation rod 603. The two ends of the telescopic spring 604 are respectively fixedly connected with the slider 602 and the installation box 1. Two groups of symmetrically distributed cams 605 are provided in the installation box 1. The cams 605 are correspondingly arranged with the slider 602 and fit with the slider 602.

A synchronous belt 607 is provided in the installation box 1. The synchronous belt 607 is respectively connected to the two sets of synchronous wheels 606. The cam 605 is driven to rotate by the motor. The cam 605 intermittently pushes the slider 602. The elastic deformation of the spring generates thrust and pull on the slider 602 to realize the vibration of the screen frame 601, thereby realizing the screening of the raw materials. The synchronous drive of the two sets of cams 605 is realized by the synchronous wheel 606 and the synchronous belt 607, so that the screen frame 601 vibrates stably to ensure the screening efficiency.

The ring 702 and the gear ring 703 are both rotatably connected to the fixed frame 701 through bearings, and the gear ring 703 is meshed with the gear 704. After being screened by the screen frame 601, some raw materials that do not meet the screening standards continue to remain on the screen frame 601, and the gear 704 is driven by the motor to rotate, and the gear ring 703 meshed with the gear 704 drives the connecting rod 705 to rotate, and the connecting rod 705 drives the mounting tube 706 and the scraper 707 to rotate. During the rotation of the scraper 707, the raw materials on the screen frame 601 are pushed until they are returned to the top of the two sets of crushing rollers 3, and are re-crushed by the crushing rollers 3 and discharged.

[0028] When the embodiment is working, the raw materials crushed by the two groups of crushing rollers 3 fall on the screen frame 601 and are driven by the motor to rotate the cam 605, which intermittently pushes the slider 602, and the elastic deformation of the spring generates thrust and pull on the slider 602 to achieve the vibration of the screen frame 601, thereby achieving the screening of the raw materials, and the synchronous drive of the two groups of cams 605 is achieved through the synchronous wheel 606 and the synchronous belt 607, so that the screen frame 601 vibrates stably to ensure the screening efficiency, and the raw materials that do not meet the screening standards continue to be screened by the screen frame 601. The raw materials on the screen frame 601 are pushed during the rotation of the scraper 707 until they are returned to the top of the two sets of crushing rollers 3, and then they are re-crushed by the crushing rollers 3 and discharged. The raw materials that do not meet the screening standards can be directly crushed for the second time without the need for additional manpower input and without stopping the raw material crushing process, thereby improving work efficiency.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
