Description

Technical Field

[0001] This utility model relates to the field of toner production technology, specifically to a feeding device for lightweight powder materials. Background Technology

[0002] Lightweight powders, characterized by small particle size, large specific surface area, strong surface adsorption, high surface energy, and low weight, are widely used in toner production. However, during the feeding process, their light weight and tendency to float easily generate significant dust in the working environment, leading to powder waste and serious health risks for workers. Furthermore, the powder can clump together on the hopper walls or clog the feeding pipe during its transfer from the hopper to the production vessel, making the feeding process difficult to control. Because the feeding process is challenging to manage, prolonged mixing time is often used to ensure uniform dispersion. However, excessive mixing and shearing time can reduce the thixotropic properties of lightweight powders, affecting the performance of the final product. Therefore, a feeding device that facilitates easy addition, reduces powder waste and dust, provides uniform addition, and does not compromise production efficiency is needed. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a feeding device for lightweight powder materials.

[0004] A feeding device for lightweight powder includes a feeding cylinder, a vibrator, and a spiral feed pipe. The device is characterized in that: a vibration spring is provided at the upper end of the vibrator, and a feeding cylinder is fixedly installed above the vibration spring. The feeding cylinder is a cylindrical body with a stirring rod at the center. The lower end of the stirring rod has stirring blades, and a variable frequency motor is installed at the upper end of the stirring rod. A feeding hopper is provided at the lower part of the feeding cylinder, and a receiving pipe is movably connected to the lower end of the feeding hopper. The receiving pipe is movably sleeved on the outside of the feeding hopper. A spiral feed pipe is vertically installed at the lower end of the receiving pipe connected to the feeding hopper. A spiral stirring rod is installed inside the spiral feed pipe, and a feed pipe is installed at the exit end of the spiral feed pipe.

[0005] The hopper is funnel-shaped, and a receiving pipe is movably connected to the lower end of the hopper. The receiving pipe is movably sleeved on the outside of the hopper.

[0006] The connection between the hopper and the receiving pipe is covered with a leak-proof rubber sleeve.

[0007] The spiral feed tube is equipped with a spiral stirring rod, which is connected to a drive motor. The drive motor drives the spiral stirring rod to work.

[0008] In operation, the lightweight powder is poured into the feeding cylinder, and the power cord is plugged in. The powder in the feeding cylinder is pushed to the discharge hopper by the stirring blades and vibrator. After passing through the discharge hopper, the powder enters the spiral feed pipe through the receiving pipe. The drive motor drives the spiral stirring rod to push the powder entering the spiral feed pipe into the production unit at a uniform speed.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the lightweight powder feeding device is convenient to add, reduces powder flying and loss, and the use of a vibrator can effectively reduce the lightweight powder that is prone to caking and sticking to the bottom of the feeding cylinder, the side wall of the feeding cylinder, and the wall of the discharge hopper, thus improving the accuracy and efficiency of feeding; the use of a spiral pusher can make the powder added at a uniform speed, preventing the mixing time from being too long due to uneven feeding.
