Therefore, we propose a vibrating screening device for conductive silver paste production to solve this problem. Utility Model Content

[0025] The filter section 21 includes a motor 211, the top surface of which is fixedly connected to the bottom surface of the tank 1. The outer surface of the output shaft of the motor 211 rotates through the bottom surface of the tank 1 and extends into the interior of the tank 1 via a sealed bearing.

The outer surface of the filter screen 210 is fixedly connected to the inner wall of the filter cylinder 201.

[0027] The outer surface of the splash guard 219 is fixedly connected to the inner wall of the filter cylinder 201. The support ring 218 is rotatably sleeved on the outer surface of the filter cylinder 201 through the bearing. The outer surface of the support ring 218 is slidably connected to the inner wall of the tank 1. By setting up the motor 211, the limiting rod 213, the limiting cylinder 214, the protective tube 217, the support ring 218, the splash guard 219, the filter screen 210 and the filter cylinder 201, in use, the filter screen 210 is used to filter the conductive silver paste. The motor 211 is started to make the filter cylinder 201 rotate. The centrifugal force is used to throw out the conductive silver, which improves the filtration efficiency of the device for the conductive silver paste. The splash guard 219 is used to prevent the conductive silver paste from overflowing the filter cylinder 201 during rotation. The support ring 218 is used to support the top of the filter cylinder 201, making the filter cylinder 201 more stable when rotating.

[0028] The outer surface of the roller 216 is rotatably connected to the inner wall of the upright 215 through a bearing seat. The top surface of the upright 215 is fixedly connected to the bottom surface of the filter cylinder 201. The bottom surface of the pad 212 is fixedly connected to the inner wall of the tank 1.

By setting the pad 212, the upright 215 and the roller 216, when the filter cylinder 201 rotates, it drives the roller 216 to rotate. When the roller 216 rolls over the top surface of the pad 212, it causes the filter cylinder 201 to vibrate up and down, thereby improving the filtration efficiency of the conductive silver paste.

[0029] The tank 1 is equipped with a cleaning section 22;

[0030] The cleaning unit 22 includes a scraper 222, a connecting rod 221 is fixedly connected to the outer surface of the scraper 222, the outer surface of the scraper 222 is slidably connected to the inner wall of the tank 1, and the cleaning unit 22 also includes an installation ring 223;

[0031] The inner wall of the tank body 1 is provided with an annular groove, and the mounting ring 223 is set inside the annular groove.

The outer surface of the connecting rod 221 extends into the sliding groove and is slidably connected to the inner wall of the filter cylinder 201. By setting the connecting rod 221, scraper 222 and mounting ring 223, the filter cylinder 201 drives the scraper 222 to rotate, which facilitates the discharge of conductive silver paste.

[0033] In use, conductive silver paste is introduced into the filter cylinder 201, and the motor 211 is started. The output shaft of the motor 211 drives the limit rod 213 to rotate, which in turn drives the limit cylinder 214 and the filter cylinder 201 to rotate. Using centrifugal force, the conductive silver paste inside the filter cylinder 201 is thrown out. When the filter cylinder 201 rotates, it drives the column 215 and the roller 216 to rotate together. The roller 216 rolls over the top surface of the pad 212, causing the roller 216 to move upward. The roller 216 drives the filter cylinder 201 to move upward, causing the filter cylinder 201 to vibrate during rotation. At the same time, the filter cylinder 201 drives the connecting rod 221 and the scraper 222 to rotate, causing the scraper 222 to scrape the inner wall of the tank 1 and the outer surface of the protective tube 217. After filtration, the filter cylinder 201 is lifted upward to clean the impurities inside the filter cylinder 201.
