It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1

[0022] like Figure 1-4 As shown, this utility model provides a color powder storage and conveying device, including a screw conveyor 1, a storage bin 2, and a discharge port 3. The storage bin 2 is fixedly connected to the input end of the screw conveyor 1, and the discharge port 3 is fixedly connected to the output end of the screw conveyor 1. A movable support 4 is rotatably connected to the bottom of the screw conveyor 1 and the storage bin 2. A guide pipe 5 is fixedly connected to the top of the storage bin 2 on the side away from the screw conveyor 1. A guide hopper 6 is fixedly connected to the top of the guide pipe 5. A wind box 7 is installed through the top of the storage bin 2. A fan blade with an upward air outlet is installed inside the wind box 7. A servo motor 8 is installed on the top surface of the wind box 7. The output end of the servo motor 8 rotates through the wind box 7 and is fixed to the top surface of the fan blade. A stirring rod 10 is rotatably connected inside the storage bin 2. The top of the stirring rod 10 rotates and extends into the wind box 7 and is fixed to the bottom of the fan blade.

[0023] The specific settings and functions of this embodiment are described below: Ventilation windows 9 are provided at the top and bottom of the air boxes 7 on both sides of the servo motor 8. Filter screens are fixed inside the ventilation windows 9. By drawing air from the storage bin 2, a negative pressure is created inside the storage bin 2, preventing the powder mist inside the storage bin 2 from overflowing through the guide hopper 6 during stirring. This also reduces the dispersion of color powder when pouring into the guide hopper 6, thus preventing color powder from entering the air box 7. The stirring rod 10 is designed to gradually narrow downwards in conjunction with the storage bin 2. The guide pipe 5 is designed to slope downwards towards the storage bin 2. The guide hopper 6 is funnel-shaped to facilitate the entry of color material into the storage bin 2.

[0024] Example 2

[0025] like Figure 1-4 As shown, the movable brackets 4 at both ends of the storage silo 2 have supporting side plates 11 fixed inside. Each of the two supporting side plates 11 has a supporting screw 12 rotatably sleeved inside. The end of the supporting screw 12 on the inner side of the supporting side plate 11 is fixed to the side wall of the storage silo 2. A fixing nut 13 is threaded onto the supporting screw 12 on the outer side of the supporting side plate 11. Reinforcing struts 14 are fixed to the top surface of the movable brackets 4 on both sides of the middle of the screw conveyor 1. Each of the two reinforcing struts 14 has an adjusting groove 15 inside, and each of the two adjusting grooves 15 has a slidingly sleeved... The two movable screws 16 are both T-shaped and placed horizontally. The end of each movable screw 16 extending to the inner side of the reinforcing support rod 14 is fixed with a fixing block 18. The two fixing blocks 18 clamp and fix the screw conveyor 1. The fixing blocks 18 are both arc-shaped and fit with the outer surface of the screw conveyor 1. The width of the fixing blocks 18 and the fixing nuts 17 is greater than the width of the adjusting groove 15. The two reinforcing support rods 14 and the fixing blocks 18 are both threaded with fixing nuts 17.

[0026] The overall effect of this embodiment is that, through the rotatable design of the screw conveyor 1 and the storage bin 2, the height of the discharge pipe 3 can be adjusted according to the height of the feeding port of the color powder storage equipment, and the screw conveyor 1 and the storage bin 2 can be moved according to the position of the color powder storage equipment, which greatly improves the applicability of the conveying device.

[0027] The operating method and working principle of this device are as follows: When a conveying device is needed, pour the color powder into the guide hopper 6. After pouring, it enters the storage bin 2 under the guidance of the guide pipe 5. At the same time, the servo motor 8 drives the stirring rod 10 and the fan blades to rotate. The fan blades draw air out of the storage bin 2, creating a negative pressure inside the storage bin 2 to prevent the color powder from drifting outwards. Simultaneously, the filter screen inside the bottom ventilation window 9 prevents the color powder from entering the air box 7. When the stirring rod 10 rotates, it stirs the color powder inside the storage bin 2 to prevent blockage at the bottom of the storage bin 2. When the position of the screw conveyor 1 needs to be adjusted, push the screw conveyor 1. When the screw conveyor 1 and the storage bin 2 are moved, and the height of the discharge pipe 3 needs to be adjusted, tighten the fixing nut 13 and the fixing nut 17 to release the clamping fixation of the support screw 12. Then, rotate the storage bin 2 to adjust the angle of the discharge pipe 3. After the adjustment is completed, pull the moving screw 16 to make it slide inside the adjusting groove 15. Move the fixing block 18 back to the side of the screw conveyor 1. Push the moving screw 16 to make the fixing block 18 abut against the outer surface of the screw conveyor 1. The fixing nut 17 clamps and reinforces the support rod 14. The fixing block 18 provides auxiliary support for the screw conveyor 1.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
