[0027] Through the above structure, the material is placed in the material box 7, and its weight is weighed by the weighing sensor 6. When the material reaches the delivery standard, the motor 4 drives the roller 3 to rotate, so that the material box 7 containing the material rotates to the discharge pipe 8 and falls. At the same time, the valve 9 is controlled and the capacity scale 18 is observed to achieve accurate quantitative delivery of the material.

[0028] Combined with Figures 2 to 4As shown, the drum 3 is provided with a plurality of grooves 10 at equal angles, a telescopic spring 11 is connected in the groove 10, one end of the telescopic spring 11 is connected with a scraper 12, the scraper 12 is made of silicone, a control box 16 is provided on the reactor top cover 1, a display screen 17 is provided on the control box 16, a single-chip microcomputer is built in the control box 16, the weighing sensor 6 is electrically connected to the control box 16, the feeding tube 19 is made of transparent material, and a capacity scale 18 is provided on the feeding tube 19.

[0029] Through the above structure, the scraper 12 is always in contact with the inner wall of the feeding barrel 2 under the action of the telescopic spring 11, so as to scrape off the material adhering to the inner wall of the feeding barrel 2. The weighing sensor 6 measures the weight of the material in the material box 7 and transmits its data to the display screen 17 through the control box 16 for display, so that personnel can understand the amount of feeding. The feeding tube 19 made of transparent material and the capacity scale 18 make it easy to understand the amount of liquid fed.

[0030] Embodiment 2

[0031] Based on the first embodiment, combined with the attached Figure 1 and Figure 2 As shown, the discharge pipe 8 passes through the reactor top cover 1, and an exhaust pump 13 is fixedly provided on the reactor top cover 1. An exhaust pipe 14 is connected to the exhaust pump 13. One end of the exhaust pipe 14 is connected to the discharge pipe 8. A dustproof cylinder 15 is inserted in the discharge pipe 8.

The dustproof cylinder 15 is used to block the material to prevent the material from entering the interior of the vacuum pump 13 along the exhaust pipe 14 and causing damage.

[0033] The specific usage is as follows:

[0034] When liquid materials are added, the valve 9 is controlled by observing the liquid and the capacity scale 18 to achieve quantitative addition of the liquid materials;

This arrangement will not cause the wires to be entangled when the roller 3 rotates. After the weight of the material in the material box 7 reaches the standard, the motor 4 is started to drive the roller 3 to rotate, and the roller 3 rotates to the discharge pipe 8 and falls. At the same time, the vacuum pump 13 acts to suck the residual material in the material box 7 into the discharge pipe 8 to ensure the accurate delivery of the material.
