Technical Field

[0001] The utility model relates to the technical field of roller pressing equipment, in particular to a device for uniformly and quantitatively conveying powder materials by adding a layer of hopper, a scraper and an automatic belt device. Background Art

[0002] Dry powder is the main raw material for supercapacitors or dry electrodes. Roller pressing equipment for dry powder forming is one of the important processes. The main prerequisite for dry powder forming is that the powder in the roller pressing equipment can be evenly discharged in the hopper.

[0003] Dry powder is usually added manually in small amounts multiple times directly into the hopper, which is time-consuming and labor-intensive. In addition, the powder itself has a certain degree of adhesion. When a lot of powder is added to the hopper at the same time, it is easy to accumulate in the hopper and cannot be evenly discharged, resulting in the electrode being of different widths and thicknesses after the dry powder is formed, and the formed material cannot be used normally. Therefore, an automatic dropping device is needed to allow the powder to fall evenly and in small amounts into the lower hopper and enter the roller press through the lower hopper for forming. Utility Model Content

[0028] Reference Figures 1 to 6 In this embodiment, the upper hopper No. 1 is installed on the conveyor belt and placed on the lower hopper; No. 2 is an adjustable scraper, which scrapes off excess non-powder on the conveyor belt through the adjustable scraper, and the amount of powder after passing through the scraper is uniformly quantitative powder. The distance between the scraper and the transmission belt is adjustable, and the amount of powder on the transmission belt can be changed by adjusting the height of the scraper; No. 3 is a transmission belt, and the powder falls onto the transmission belt through the upper hopper and is transported to the lower hopper through the conveyor belt; No. 4 is a material receiving box, and the excess material scraped off by the adjustable scraper is received by the material receiving box to prevent waste of powder; No. 5 is a motor reducer, which drives the transmission belt through the motor reducer to drive the powder to fall uniformly and quantitatively into the lower hopper; in this embodiment, the scraper is a V-shaped scraper, and the two strips in the angled shape in the V-shaped scraper have an angle less than 90 degrees with the transmission direction of the conveyor belt.

[0029] Working principle:

[0030] After the powder is manually added to the upper hopper, the powder falls onto the transmission belt. After adjusting the distance between the adjustable scraper and the transmission belt, the excess powder on the conveyor belt is hung off by the adjustable scraper. The remaining uniform and quantitative powder is transported to the lower hopper through the transmission belt, and then falls between the two rollers of the roller press to be rolled and formed. The running speed of the transmission belt can match the speed of the roller press and automatically adjust the speed, thereby automatically changing the amount of powder conveying.

[0031] In this embodiment, a lifting assembly is also provided for adjusting the height of the scraper blade. Figure 5 and Figure 6 The lifting assembly includes a lifting screw and a fixed frame; the fixed frame is located on one side of the conveyor belt, and includes two columns with vertical guide grooves and a top plate; the column is fixedly connected to the top plate located on the top thereof, and the two vertical guide grooves on the column are arranged oppositely; the lifting screw is located between the two columns, the bottom end of which is driven to rotate by a motor combination, and the top end is connected to the top plate bearing;

[0032] The lifting screw is provided with a moving block threadably connected thereto, and two sides of the moving block are constrained in corresponding vertical guide grooves; the V-shaped scraper is fixedly connected to the moving block and moves up and down with the moving block.

[0033] In this embodiment, a control system is also provided for adjusting the material discharge of the hopper, wherein the control center is implemented by FPGA, which is used to retrieve the parameters of the storage module and translate them into action instructions and send them to the corresponding drive module.

[0034] The storage module exists in the form of an Excel table, which records a variety of discharge parameters, including the parameters of the height of the lifting screw and the speed parameters of the conveyor belt motor;

[0035] The driving module of the motor combination is used to receive instructions from the control center and set the travel time of the motor combination;

[0036] The drive module of the transmission motor is used to receive the action instructions from the control center and set its travel speed.
