[0022] Embodiment 1

[0023] Please refer to Figures 1-5, the utility model provides a technical solution: a chemical safety feeding device, which includes a cylinder body 1. A cylinder cover 2 is fixedly connected to the top of the cylinder body 1. A motor 6 is fixedly connected to the surface of the cylinder cover 2. The output end of the motor 6 is fixedly connected to a cylindrical rod 7. Stirring rods 8 and connecting rods 9 are fixedly connected to the surface of the cylindrical rod 7. A chute 10 is formed on one end surface of the connecting rod 9. A slider 11 is slidably connected to the inside of the chute 10. A scraper 13 is fixedly connected to the surface of the slider 11. A spring 12 is arranged inside the chute 10. The spring 12 is fixedly connected to the slider 11. A discharge pipe 4 is fixedly connected to the bottom of the cylinder body 1. A valve 5 is fixedly connected to the surface of the discharge pipe 4. A funnel 3 is fixedly connected to the surface of the cylinder cover 2. The number of the scrapers 13 is two groups. The two groups of scrapers 13 are symmetrically distributed on both sides of the middle part of the cylinder body 1. Here, the working efficiency of scraping the inner wall of the cylinder body 1 can be further improved. An observation window 20 is embedded in the surface of the cylinder body 1. The observation window 20 is made of transparent glass material. Here, the raw materials in the cylinder body 1 can be observed, which is convenient for mastering the stirring condition of the raw materials. A sealing ring 14 is arranged between the cylinder body 1 and the cylinder cover 2. The sealing ring 14 is made of rubber material. Here, the sealing effect between the cylinder cover 2 and the cylinder body 1 can be improved.

[0024] Embodiment 2

[0025] Please refer to Figure 4 , a fixing block 15 is fixedly connected to the surface of the cylinder body 1. A screw rod 16 is threadedly connected to the inside of the fixing block 15. A clamping block 17 is rotatably connected to the surface of the screw rod 16. An adjusting knob 18 is fixedly connected to the bottom of the screw rod 16. The clamping block 17 abuts against the surface of the cylinder cover 2. Here, the disassembly and assembly between the cylinder body 1 and the cylinder cover 2 can be facilitated, making the installation and disassembly of the cylinder cover 2 more convenient, and no tools are needed, which improves the convenience of maintaining or replacing the workpieces inside the cylinder body 1 in the later stage. A clamping groove 19 is formed on the surface of the cylinder cover 2. The clamping block 17 is clamped inside the clamping groove 19. Here, the clamping block 17 abutting against the cylinder cover 2 can be limited, so that the clamping block 17 will not rotate accidentally when fixing the cylinder cover 2, so as not to affect the fixing effect of the cylinder cover 2.

[0026] Working principle: During use, first add raw materials into the interior of the cylinder body 1 through the funnel 3, and then start the motor 6. The output end of the motor 6 drives the cylindrical rod 7 to rotate. While the cylindrical rod 7 rotates, it drives the clamping plate and the connecting rod 9 to rotate. Under the action of the elastic force of the spring 12 that pushes the slider 11 in the chute 10, the scraper 13 always abuts against the inner wall of the cylinder body 1. Subsequently, the scraper 13 rotates along with the stirring, scraping the raw materials attached to the inner wall of the cylinder body 1, enabling the scraped raw materials to continue to participate in the stirring and mixing work, realizing the scraping of the raw materials attached to the inner wall of the cylinder body 1, avoiding the phenomenon of raw materials caking on the inner wall of the cylinder body 1, enabling the raw materials to be fully mixed. At the same time, under the action of the spring 12, the cutting edge of the scraper 13 always fits the inner wall of the cylinder body 1, which is beneficial to improving the service life of the scraper 13. The stirring condition of the raw materials in the cylinder body 1 can be observed through the observation window 20. The sealing ring 14 can improve the sealing effect between the cylinder body 1 and the cylinder cover 2. When the raw materials are stirred well, open the valve 5 on the discharge pipe 4 to discharge the stirred raw materials through the discharge pipe 4. When the device needs to maintain or replace the workpiece in the cylinder body 1 after long-term use, first rotate the adjustment knob 18. The adjustment knob 18 drives the screw rod 16 to rotate inside the fixed block 15 and pushes the clamping blocks 17 to move towards each other. When the clamping blocks 17 disengage from the card slots 19, rotate the clamping blocks 17 to move the clamping blocks 17 away from above the cylinder cover 2, and then take out the cylinder cover 2 together with the workpiece in the cylinder body 1. Subsequently, the stirring rod 8 or the scraper 13 can be repaired or maintained.
