[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3The glass fiber reinforced plastic production feeding device shown in the figure includes a mixing tank 1 and a sealing cover 2. A liquid tank 3 is fixedly connected to one side of the mixing tank 1. The mixing tank 1 is located on the upper side of the liquid tank 3 and is fixedly connected to a support plate 4. The bottom end of the support plate 4 is fixedly connected to a first electric push rod 5. The output end of the first electric push rod 5 is fixedly connected to a pressure plate 6. The first electric push rod 5 can drive the pressure plate 6 to move downward and squeeze the liquid material in the liquid tank 3. A telescopic motor is provided on one side of the liquid inlet pipe 7, and the end of the telescopic motor is plugged into the upper side of the liquid inlet pipe 7 to achieve the effect of sealing the bottom side of the liquid tank 3. The pressure plate 6 corresponds to the liquid tank 3. The bottom end of the liquid tank 3 is fixedly connected to a liquid inlet pipe 7. One end of the liquid inlet pipe 7 is fixedly connected to a liquid separating ring 8. The liquid raw material enters the liquid separating ring 8 from the bottom side of the liquid tank 3 through the liquid inlet pipe 7 and is then evenly sprayed out through the nozzle 9. A support rod 21 is fixedly connected to one side of the liquid separating ring 8, and the support rod 21 is fixedly connected to the mixing tank 1. The bottom of the liquid separating ring 8 The ends are evenly fixedly connected with a nozzle 9, the upper end of the sealing cover 2 is fixedly connected with a fixed cylinder 10, the upper end of the fixed cylinder 10 is fixedly connected with a first motor, the first motor drives the rotating rod 11 to rotate, which can make the scraper 12 rotate in the distribution frame 13, prompting the additive raw material to fall from the guide hole 18 into the mixing tank 1, and complete the mixing of the powder and liquid. The output end of the first motor is fixedly connected with the rotating rod 11, and the bottom side of the rotating rod 11 is fixedly connected with the scraper 12, the scraper 12 contacts the distribution frame 13, and the bottom end of the distribution frame 13 is evenly provided with guide holes 18. The upper side of the fixed cylinder 10 is fixedly connected with a guide cylinder 15, and one side of the guide cylinder 15 is fixedly connected to the second motor. The output end of the second motor is fixedly connected with a spiral feeding rod 16, and one side of the upper end of the guide cylinder 15 is fixedly connected to the powder barrel 17. Starting the second motor drives the spiral feeding rod 16 to rotate, which can prompt the material in the powder barrel 17 to enter the mixing tank 1.

[0018] Among them, the fan 19 is fixedly connected to the bottom end of the rotating rod 11, and the material separation frame 13 is rotatably connected to the rotating rod 11 through a sealed bearing. By setting the fan 19, a downward airflow can be generated, and the powder on the upper side of the liquid separation ring 8 can fall off to the bottom side of the mixing tank 1, which is convenient for mixing.

[0019] The bottom side of the cover 2 is fixedly connected to a bracket 14, and the bracket 14 is fixedly connected to the upper end of the material distribution frame 13. By providing the bracket 14, the position limit of the material distribution frame 13 is increased, which facilitates material discharge.

[0021] The air pump 20 is fixedly connected to one side of the fixed cylinder 10 , and the output end of the air pump 20 is located inside the fixed cylinder 10 . By arranging the air pump 20 , an impact airflow can be generated and the falling of the powder can be promoted.

[0022] Working principle: The liquid material is quantitatively added into the liquid tank 3, and then the pressure plate 6 and the first electric push rod 5 are extended to achieve the closure of the liquid tank 3, and then the additive raw material is added into the powder barrel 17, and then under the action of the spiral feeding rod 16, the powder enters the fixed barrel 10, and at the same time the air pump 20 blows air to make the glass fiber reinforced plastic powder and additives evenly dispersed. Under the action of gravity, the powder falls into the material distribution frame 13, and the rotating rod 11 cooperates with the scraper 12 to make the powder fall from the guide hole 18 to the bottom side of the mixing tank 1. The powder is evenly dispersed, avoiding the agglomeration caused by sticking to water vapor. At this time, the glass fiber reinforced plastic raw material in the liquid tank 3 enters the liquid separation ring 8 through the liquid inlet pipe 7, and then falls evenly through the nozzle 9, and is stirred by the stirring rod to achieve a uniform mixing effect.
