Description

Technical Field

[0001] This utility model relates to the technical field of silver powder production equipment, specifically to a convenient cleaning tool for silver powder adhering to the wall. Background Technology

[0002] Because of the line or surface contact between the particles, flake silver powder has a relatively low resistance compared to the point contact of spherical silver powder. It is a good conductive filler and has a wide range of applications in many fields such as microelectronics, flexible display technology, and photovoltaic industry.

[0003] The production process of flake silver powder for electronic materials generally includes reduction, solid-liquid separation, drying, grinding and sieving. Among them, the grinding process is the key step in forming flake silver powder, which includes dry grinding and wet grinding. Dry grinding involves first drying the separated silver powder, and then putting the dried silver powder and grinding balls into a ball mill for rotation and friction to grind and disperse it, thereby forming flake silver powder.

[0004] Traditionally, ball mills with hexagonal cylinders are used to grind flake silver powder. However, after the silver powder is discharged from the mill, it tends to stick to the inner wall, requiring individual cleaning of each surface of the mill's inner wall. This process is inefficient and often results in incomplete cleaning. Therefore, this application proposes a convenient cleaning fixture for silver powder sticking to the mill walls. Utility Model Content

[0005] To overcome the problems in the background technology, this utility model provides a convenient cleaning tool for sticky silver powder, which solves the problems of low cleaning efficiency and incomplete cleaning when using a ball mill with a hexagonal cylinder to grind flake silver powder.

[0006] A convenient cleaning tool for wall-adhesive silver powder includes a central shaft, an adjusting sleeve, a tension rod, an adjusting rod, a support rod, and a scraper. The tension rod, adjusting rod, and support rod are evenly arranged in six groups around the central shaft. The adjusting sleeve is threaded onto the central shaft, and the two ends of the central shaft extend out of the adjusting sleeve. A connecting ring is rotatably installed on the adjusting sleeve. The bottom end of the tension rod is hinged to the connecting ring, the top end of the tension rod is hinged to the middle of the adjusting rod, the top end of the adjusting rod is hinged to the top of the central shaft, and the lower end of the adjusting rod is hinged to the bottom end of the support rod. The scraper is vertically installed on the top of the support rod to form a hexagonal plate surface.

[0007] Furthermore, a tensioning spring is connected between the adjusting rod and the support rod, and the tensioning spring is located on the rear side of the hinge seat of the support rod.

[0008] Furthermore, the scrapers installed adjacent to each other at the top of the support rod are staggered vertically.

[0009] Furthermore, the front end of the adjusting sleeve is provided with a rotating handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This application features a scraper with a hexagonal surface that can cooperate with the hexagonal inner wall of a ball mill to scrape away silver powder adhering to the wall, resulting in high cleaning efficiency. At the same time, the scraper can be retracted and adjusted via a tension rod, adjusting rod, support rod, and adjusting sleeve, extending into the bottom of the ball mill before retracting, making the cleaning more thorough and preventing silver powder from being pushed in or spread with the scraper. This solves the problems of low cleaning efficiency and incomplete cleaning that exist when grinding flaky silver powder using a ball mill with a hexagonal cylinder. Attached Figure Description

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] This utility model proposes a convenient cleaning tool for adhering silver powder, see reference. Figure 1-3 A convenient cleaning tool for wall-adhesive silver powder includes a central shaft 1, an adjusting sleeve 2, a tension rod 3, an adjusting rod 4, a support rod 5, and a scraper 6. The tension rod 3, adjusting rod 4, and support rod 5 are evenly arranged in six groups around the central shaft 1. The adjusting sleeve 2 is threadedly installed on the central shaft 1, and both ends of the central shaft 1 extend out of the adjusting sleeve 2. A connecting ring 21 is rotatably installed on the adjusting sleeve 2. The bottom end of the tension rod 3 is hinged to the connecting ring 21, the top end of the tension rod 3 is hinged to the middle of the adjusting rod 4, the top end of the adjusting rod 4 is hinged to the top end of the central shaft 1, and the lower end of the adjusting rod 4 is hinged to the bottom end of the support rod 5. The scraper 6 is vertically installed on the top of the support rod 5 to form a hexagonal plate surface.

[0019] The rotation of the adjusting sleeve 2 on the central shaft 1 can drive the connecting ring 21 to move back and forth. The movement of the connecting ring 21 can drive the hinged tension rod 3, adjusting rod 4, and support rod 5 to be pulled, so that the scraper 6 can be retracted and unfolded. This makes it easier for the scraper 6 to extend into the bottom of the ball mill and then unfold, making the cleaning cleaner and more thorough. The hexagonal scraper 6 can fit with the inner wall and corner gaps of the ball mill, making the silver powder cleaning more convenient and clean.

[0020] See Figure 1-3 A tensioning spring 7 is connected between the adjusting rod 4 and the support rod 5. The tensioning spring 7 is located on the rear side of the hinge seat of the support rod 5, so that the scraper 6 can automatically retract as the connecting ring 21 moves backward.

[0021] See Figure 1-3 The scrapers 6 installed adjacent to each other at the top of the support rod 5 are staggered vertically to facilitate the retraction and unfolding of the scrapers 6 without affecting each other. When fully unfolded, the scraper 6 has a hexagonal surface.

[0022] See Figure 1-3 The front end of the adjusting sleeve 2 is provided with a rotating handle 22 for easy operation of the adjusting sleeve 2.

[0023] Work process:

[0024] Before cleaning, rotate the adjusting sleeve 2 backward on the central shaft 1 to move the connecting ring 21 backward and drive the tension rod 3 to retract the scraper 6. After the scraper 6 extends into the bottom of the ball mill, rotate the adjusting sleeve 2 forward on the central shaft 1 to unfold the scraper 6 and make it contact the cylinder wall. Pull the scraper 6 out through the central shaft 1 to clean out the silver powder stuck to the wall.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
