By starting the screw pump 202, the mixed material in the mixing tank 1 is quickly drawn out through the connecting pipe 201. The other end of the screw pump 202 is connected to a metering cylinder 203. A float plate 204 is slidably connected to the inner wall of the metering cylinder 203. After the material enters the metering cylinder 203 through the screw pump 202, the material will drive the float plate 204 to move upward. A cylinder 205 is fixedly connected to the top of the metering cylinder 203. One end of the cylinder 205 passes through the top of the metering cylinder 203 and is set on the top of the float plate 204.

[0042] Specifically, one end of the connecting pipe 201 is connected to the right side of the outer wall of the mixing tank 1, ensuring that the material can flow smoothly out of the mixing tank 1. The other end of the connecting pipe 201 is tightly connected to the screw pump 202. The screw pump 202 generates a strong suction force through the rotation of its internal screw, thereby quickly drawing the mixed material in the mixing tank 1 out through the connecting pipe 201. The output end of the screw pump 202 is connected to the metering cylinder 203. A float 204 is installed on the inner wall of the metering cylinder 203. When the material is pumped into the metering cylinder 203 by the screw pump 202, the weight of the material will push the float 204 upward. The displacement of the float 204 is directly proportional to the amount of material. One end of the cylinder 205 passes through the top of the metering cylinder 203 and is set on the top of the float 204. The cylinder 205 can control the discharge amount of the material according to the position change of the float 204.

The metering cylinder 203 is used to balance the internal pressure during material conveying, preventing excessive internal pressure from affecting the material conveying efficiency. A scale window 207 is fixedly connected to the front of the outer wall of the metering cylinder 203, through which the operator can clearly see the position of the float 204 and thus accurately determine the filling amount of material. A sensing plate 210 is slidably connected to the outer wall of the support rod 208, and a reinforcing bolt 209 is threadedly connected to the right side of the sensing plate 210. The operator adjusts the position of the sensing plate 210 according to the scale window 207 and fixes it firmly to the support rod 208 by rotating the reinforcing bolt 209. When the float 204 rises to the position of the sensing plate 210 as the material increases, the sensing plate 210 will immediately send a signal to control the screw pump 202 to stop conveying material. The cylinder 205 will receive the signal and start, pressing down the float 204, thereby accurately discharging the material in the metering cylinder 203 into the mold.

A placement plate 17 is fixedly connected to the bottom of the controller 23. The rear side of the placement plate 17 is fixedly connected to the front side of the outer wall of the mixing tank 1. Guardrails 21 are fixedly connected to the front and rear sides of the top of the base 19. Connecting plates 20 are fixedly connected to all four sides of the outer wall of the base 19. Fixing parts 14 are fixedly connected to all four sides of the outer wall of the mixing tank 1. Buckles 15 are fixedly connected to all four sides of the outer wall of the top cover 3.

[0044] Specifically, the controller 23 facilitates simple operation and control of the entire device by the workers. The controller 23 is reinforced on the front side of the mixing tank 1 by the placement plate 17 to ensure the stability of the controller 23. The guardrail 21 on the top of the base 19 ensures the installation of the operator and avoids unnecessary personnel from approaching. The fastener 14 and the buckle 15 ensure the sealing between the mixing tank 1 and the top cover 3.

[0045] Working principle: First, the servo motor 4 drives the stirring blades 5 to convey the material deposited at the bottom of the mixing tank 1 upward. When the hollow column 22 rotates, multiple stirring rods 7 fully stir the starch and plastic. The connecting bolt 11 is inserted from the top of the hollow column 22 by rotation. Multiple connecting buckles 10 are connected to each other through the connecting bolt 11 to lock the telescopic rod 8. The inner walls of multiple connecting buckles 10 are threaded to the outer wall of the connecting bolt 11. When the connecting bolt 11 is removed, the telescopic rod 8 unfolds to both sides under the action of the spring 12, so that the scraper fits against the inner wall of the mixing tank 1 of different sizes to achieve full scraping treatment.

[0046] Furthermore, by starting the screw pump 202, the mixed material in the mixing tank 1 is quickly extracted through the connecting pipe 201. After the material enters the metering cylinder 203 through the screw pump 202, the material will drive the float 204 to move upward. The sensing plate 210 is adjusted according to the scale window 207 and reinforced on the support rod 208 by rotating the reinforcing bolt 209. When the float 204 reaches the position of the sensing plate 210, the sensing plate 210 will control the screw pump 202 to stop conveying material and start the cylinder 205 to press the float 204 downward, so that the material is metered into the mold, ensuring the accuracy of material measurement and improving production efficiency.
