When the production device described in the present invention is working, the motor of the grinding mechanism does not participate in the vibration, which reduces the vibration amplitude of the device when it is working, avoids doing useless work, and reduces energy consumption; the tablet pressing mechanism adopts a linear module structure, the tablet pressing mold control accuracy is accurate, the structure is easier to install, debug and maintain, and the transfer mechanism adopts a multi-cylinder combination mode, the feedback is stable, and the cost is reduced. The sample preparation device for material detection and analysis described in the present invention has a simple and compact structure and high efficiency. It can complete sample preparation efficiently and with high quality. It has a high degree of automation and can complete one sample in an average of 6-7 minutes.

[0031] The grinding mechanism 2 comprises a vibration platform 2-1, a motor 2-2 is installed below the vibration platform 2-1, a plurality of shock absorbers 2-4 are arranged on the platform plate 2-3 above the vibration platform 2-1, a grinding component 2-5 is arranged above the plurality of shock absorbers 2-4, the grinding component 2-5 comprises an eccentrically arranged main drive shaft 2-6, the lower end of the main drive shaft 2-6 is connected to the motor 2-2 through a coupling 2-7, a grinding support bracket 2-8 and a grinding bowl bracket 2-9 are fixedly connected to the main drive shaft 2-6, the upper end of the shock absorber 2-4 is connected to the grinding support bracket 2-8, the outer side of the grinding bowl 2-10 is against the grinding bowl bracket 2-9, a grinding column 2-11 and a grinding ring 2-12 are arranged in the grinding bowl 2-10, a driven shaft 2-13 is also arranged on the grinding support bracket 2-8, and a grinding bowl upper cover 2-14 is arranged on the grinding bowl 2-10. It is composed of a grinding component (grinding unit), a vibration driver and a vibration platform. The vibration driver consists of a motor (drive motor) and a coupling (preferably a telescopic coupling). The motor is connected to the lower end of the vibration platform through anti-loosening bolts to provide vibration power for the grinding parts. The vibration generated during the vibration of the grinding parts is filtered out by the shock absorber (preferably a spring shock absorber) connecting the grinding parts and the vibration platform, reducing the vibration impact and noise of the grinding parts on the whole machine. The vibration of the grinding parts is powered by the main drive shaft, and the movement of the grinding bowl is constrained by two driven shafts. The main drive shaft and the driven shaft are eccentric shafts with equal eccentricity, so that the grinding parts can achieve regular swing under the excitation of the vibration driver. The vibration power of the main drive shaft comes from the input of the vibration driver. The main driving shaft is connected to the top of the coupling and is connected in series with the counterweight, the grinding support bracket and the grinding bowl bracket in sequence. The top is limited by the pressure plate and the locking nut. After receiving the power transmitted by the coupling, the main driving shaft will drive the entire grinding bowl bracket to swing eccentrically. The grinding bowl bracket drives the grinding bowl and the grinding bowl cover (including the grinding wall and the grinding cover, the grinding ring and the grinding center column in the cavity formed by the grinding wall and the grinding cover) on it. They will be displaced by the impact and friction, thereby forming multiple collisions with each other, so as to achieve the grinding of the granular materials falling from the material pipe by impact and crushing. The vibration mill structure of the present invention effectively improves the efficiency and quality of vibration grinding, enables the material to be reliably crushed into tiny powders that meet the requirements of sample production and molding, and at the same time reduces the external overall swing of the grinding parts while ensuring normal grinding, ensures that the motor does not participate in the vibration, reduces the useless work of the motor, avoids impact on the motor, reduces the overall size, and improves the overall performance.

[0032] The discharge port at the lower end of the grinding bowl 2-10 of the grinding mechanism 2 is connected to the extension pipeline 2-15, and a discharge pipe 2-16 is arranged on the extension pipeline 2-15, and a feed pipe 2-17 is arranged on the upper cover 2-14 of the grinding bowl. In the above structure, when the material needs to be ground, the material to be ground enters the grinding bowl from the feed pipe, and is ground by the vibration of the grinding bowl, the grinding column and the grinding ring. After the grinding is completed, the discharge cylinder contracts and drives the push rod to move downward for a distance, so that the material slides from the discharge port at the lower end of the grinding bowl 2-10 through the extension pipeline 2-15 to the discharge pipe, and is introduced into other equipment for the next link processing. The discharge cylinder 2-18 is arranged at the lower end of the extension pipeline 2-15, and a push rod 2-19 is arranged in the extension pipeline 2-1. The lower end of the push rod 2-19 is connected to the discharge cylinder 2-18, and the blocking member 2-20 at the upper end of the push rod 2-19 is set to a structure with the same shape and size as the discharge port at the lower end of the grinding bowl 2-10. In the above structure, after the discharge cylinder extends to drive the push rod to move upward, the blocking member will close the discharge port at the lower end of the grinding bowl 2-10 to achieve sealing. At this time, the material can be reliably ground in the grinding bowl without falling out.

[0033] A material pouring port 1-9 is provided at the lower end of the device housing 1-1. In the above structure, the material pouring port 1-9 is located at the bottom and is in a trumpet-shaped structure, which is convenient for quick and clean pouring of materials. A vibrator is provided on the side of the device housing 1-1. In the above structure, when pouring out materials, the control component controls the vibrator to start vibrating, so as to facilitate faster discharge of materials. The rotary cover 1-7 includes a cover opening body 1-13 and a cover pressing cylinder 1-14. The cover pressing cylinder can be lifted and rotated, so that the cover opening body moves up and rotates to open the opening. Then, the powdered or granular material is poured into the quantitative material cup manually or mechanically.

[0034] The motor 2-2 is configured to be able to drive the main drive shaft 2-6 to eccentrically swing through the coupling 2-7. When the motor 2-2 drives the main drive shaft 6 to eccentrically swing through the coupling 2-7, the main drive shaft 2-6 is configured to be able to drive the grinding component 2-5 to grind the material. A vibration driver 2-25 is arranged between the coupling 2-6 and the motor 2-2. When the main drive shaft 6 of the grinding component 2-5 drives the grinding component 2-5 to grind the material, the grinding bowl 2-10 of the grinding component 2-5, the grinding ring 2-12 in the cavity formed by the upper cover 2-14 of the grinding bowl and the grinding center column 2-11 are displaced by the impact and friction, thereby forming a collision with each other, so as to achieve the structure of impacting and crushing the granular material falling from the feed pipe 2-17, so that the granular material is crushed into a usable tiny powder. The above structure can efficiently realize the vibration grinding of the material through the action of the grinding component.
