[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1 To address the problems of inconvenient maintenance, significant material residue, and substantial raw material waste associated with existing screening devices, please refer to [link / reference needed]. Figures 1-3 This utility model provides a novel aluminum silver paste sieving device, comprising: The screen cylinder 1 includes a top cover 101 and multiple vertically stacked frames 102. Each frame 102 is equipped with a drawer-type screen 105 for multi-stage screening of aluminum silver paste. The top cover 101 is equipped with a feed inlet 104. Fixed clamps 103 are provided between adjacent frames 102 and between frames 102 and top cover 101 to achieve a sealed connection, ensuring the independence of each screening chamber and the stability of the overall structure. The base 2 is used to support the screen cylinder 1 and apply vibration to the whole. The top center of the base 2 is provided with a drive motor 201 to provide vibration excitation. The top edge of the base 2 is provided with multiple support springs 202 evenly distributed in the circumferential direction. The multiple support springs 202 together support the screen cylinder 1. The collecting component 3 is stored in the side area of ​​the base 2 when not in operation, and moves to the side and below the target screen 105 when in operation to collect the dripping aluminum silver paste when the screen 105 is pulled out. The material collection assembly 3 includes a mounting frame 301 and a material collection tray 302 that is detachably mounted on the mounting frame 301; a support plate 203 for storing the material collection assembly 3 in a non-working state is also fixed on the outer wall of the base 2. The scraping assembly 4, mounted on the mounting bracket 301, is used to scrape off the aluminum silver paste adhering to the surface when the screen 105 is pulled out.

[0019] like Figures 5-6 As shown, the scraping assembly 4 includes two scraping strips 401, and each scraping strip 401 has a second movable rod 402 fixedly provided at both ends; both ends of the mounting bracket 301 are provided with through holes 309, the second movable rod 402 is movably inserted into the inner wall of the through hole 309, and a second spring 403 is sleeved on the second movable rod 402 between the inner wall of the through hole 309 and the scraping strip 401. When the collecting component 3 is positioned, during the extraction of the screen 105, the two scraper strips 401 are first separated. As the screen 105 is continuously extracted, the scraper strips 401 come into contact with the surface of the screen 105, generating a scraping effect. The second spring 403 provides elastic buffering force, allowing the scraper strips 401 to retract slightly along the axial direction of the second movable rod 402, avoiding rigid impact that could damage the surface of the screen 105. At the same time, the elastic pressure ensures that the scraper strips 401 always adhere to the surface of the screen 105, effectively removing the attached residual slurry. The dual scraping surfaces scrape simultaneously, resulting in higher efficiency. Through the scraper component 4, during the extraction of the drawer-type screen 105, the adhering aluminum silver paste on its bottom and top surfaces can be automatically scraped off, achieving immediate collection and centralized recycling, significantly reducing raw material loss.

[0020] In use, the aluminum silver paste enters the screen cylinder 1 through the feed inlet 104 on the top cover 101, and undergoes multi-stage screening by passing through each drawer-type screen 105. Coarse particles are trapped on the corresponding screen 105 and discharged from the side discharge port, while qualified fine paste falls down step by step and is finally collected from the bottom discharge port. The drive motor 201 in the base 2 generates excitation force through the eccentric block, which is transmitted to the screen cylinder 1 through the support spring 202, so that the material is evenly distributed on the surface of the screen 105; when a certain screen 1 When cleaning or replacement is required, move the mounting frame 301 and its collection tray 302 and scraper assembly 4 from the support plate 203 on the side of the base 2 to the side and below the target screen 105, ensuring that the collection assembly 3 is firmly in place. Pull the target screen 105 out horizontally. During the movement, the scraper assembly 4 scrapes off the residual slurry. The scraped aluminum silver paste falls directly into the collection tray 302 directly below. After cleaning, the collection tray 302 can be removed as a whole for easy recycling of the aluminum silver paste.

[0021] Example 2 Based on Embodiment 1, in order to enable the mounting bracket 301 to move and precisely position itself below the screen 105 at any target level, thereby adapting to the maintenance needs of screens 105 of different heights, such as... Figures 3-4As shown, the material collection assembly 3 also includes a support mechanism for adjusting the position of the mounting bracket 301.

[0022] The support mechanism includes two fixed seats 304 symmetrically arranged at both ends of the mounting frame 301, a telescopic rod 306, and a fixed rod 307; the two fixed seats 304 jointly support the mounting frame 301, and a first magnet block 308 is fixedly provided on the side of the fixed seat 304 facing the screen cylinder 1, and a second magnet block 106 that attracts the first magnet block 308 is fixedly provided on the outer wall of the frame 102; the fixed rod 307 is fixedly provided on the outer wall of the base 2, and one end of the telescopic rod 306 is rotatably connected to the fixed seat 304, and the other end is rotatably connected to the fixed rod 307.

[0023] Both ends of the mounting bracket 301 are fixedly provided with a first movable rod 303, which movably passes through the fixed seat 304. A first spring 305 is sleeved on the first movable rod 303 between the fixed seat 304 and the mounting bracket 301. The material collection plate 302 matches the contour of the screen cylinder 1 to ensure effective reception of the aluminum silver paste on the surface of the screen 105.

[0024] When maintaining a certain level of screen 105, the idle material collection assembly 3 is removed from the support plate 203 on the outer wall of the base 2. First, the mounting bracket 301 is pulled slightly outward, and then pushed towards the screen cylinder 1. This action causes the telescopic rod 306 to gradually extend, moving the fixed seat 304 towards the screen cylinder 1 until the first magnet block 308 is attracted and positioned with the second magnet block 106 of the corresponding frame 102. At this time, the mounting bracket 301 is released, and the first movable rods 303 at both ends of the mounting bracket 301 spring back. Under the elastic restoring force of the spring 305, the mounting bracket 301 is pushed to further conform to the outer contour of the screen cylinder 1, so that the collecting plate 302 and the screen cylinder 1 are tightly fitted to form an effective sealed receiving cavity to prevent slurry leakage. After the screen 105 is pulled out, the mounting bracket 301 is pulled outward again and pushed to overcome the magnetic attraction between the first magnet block 308 and the second magnet block 106, so that the two are separated. Then the collecting assembly 3 is pushed back to the support plate 203 in the opposite direction to complete the reset and prepare for the next use.

[0025] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
