Description

Technical Field

[0001] This utility model belongs to the field of powder coating sieving technology, specifically relating to a powder coating processing sieving device. Background Technology

[0002] The sieving device in powder coating processing plays a crucial role in the production and processing of powder coatings. It is mainly used for sieving, removing impurities, and ensuring the uniformity and fineness of the powder coating.

[0003] Existing powder coating screening devices use vibration to screen powder coatings, removing large particles, lumps, and impurities. However, during vibration screening, the powder coatings poured into the vibrating screen may accumulate and agglomerate. Furthermore, since there is no stirring or dispersing structure inside the vibrating screen, the screening effect becomes poor. Therefore, we propose a powder coating processing screening device. Summary of the Invention

[0004] The purpose of this utility model is to provide a powder coating processing sieving device to solve the problem of agglomeration that easily occurs during the vibrating sieving of powder coatings as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder coating processing sieving device, including a base, a vibrating screen fixed at the top of the base, a feed inlet fixed at the top of the vibrating screen, a sieving and dispersing mechanism provided inside the vibrating screen, a dustproof mechanism provided at the top of the feed inlet, and the sieving and dispersing mechanism including a drive component and an adaptive stirring and dispersing component.

[0006] Preferably, the drive assembly includes a bearing seat fixed at the center of the bottom of the vibrating screen and a drive motor fixed on the inner wall of the vibrating screen extending to the top of the bearing seat. The bottom of the drive motor is fixed with a shaft connected to the bearing seat.

[0007] Preferably, the adaptive stirring and dispersing assembly includes rotating rods symmetrically fixed on both sides of the shaft and a scraper disposed at the bottom end of the rotating rod, the scraper being in contact with the bottom end of the vibrating screen.

[0008] Preferably, the bottom end of the rotating rod is provided with an internal groove at equal intervals and a telescopic rod fixed at equal intervals to the top end of the rotating rod, and the telescopic rod is engaged with the internal groove.

[0009] Preferably, the built-in groove is provided with a telescopic spring that is connected to the telescopic rod.

[0010] Preferably, a guide plate is fixed to the top of the drive motor.

[0011] Preferably, the dustproof mechanism includes a dustproof cover fitted onto the top of the feed inlet, and rubber blocks are symmetrically fixed to the inner wall of the dustproof cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through its designed bearing housing, drive motor, shaft, rotating rod, and scraper, enables the stirring and dispersing of agglomerated powder coatings during vibrating screening, facilitating filtration. Furthermore, the designed pouring plate prevents the powder coating from touching the top of the drive motor after being poured into the feed inlet. Compared to existing technologies, this significantly simplifies the screening process for powder coatings. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a powder coating processing sieving device, including a base 1, a vibrating screen 2 fixed at the top of the base 1, a feed inlet 3 fixed at the top of the vibrating screen 2, a sieving and dispersing mechanism inside the vibrating screen 2, and a dustproof mechanism at the top of the feed inlet 3. The sieving and dispersing mechanism includes a drive component and an adaptive stirring and dispersing component.

[0021] In this embodiment, preferably, the driving assembly includes a bearing seat 100 fixed at the center of the bottom of the vibrating screen 2 and a drive motor 101 fixed on the inner wall of the vibrating screen 2 extending to the top of the bearing seat 100. The bottom of the drive motor 101 is fixed with a shaft 102 connected to the bearing seat 100, which can drive the rotating rod 200 to rotate.

[0022] In this embodiment, preferably, the adaptive stirring and dispersing component includes rotating rods 200 symmetrically fixed on both sides of the shaft 102 and scraper 201 disposed at the bottom of the rotating rods 200. The scraper 201 is in contact with the bottom of the vibrating screen 2 and can disperse the accumulated powder coating.

[0023] In this embodiment, preferably, the bottom end of the rotating rod 200 is provided with an internal groove 300 at equal intervals and a telescopic rod 301 is fixed at equal intervals to the top end of the rotating rod 200. The telescopic rod 301 is engaged with the internal groove 300, which can adaptively adjust the position of the scraper 201.

[0024] In this embodiment, preferably, the built-in groove 300 is provided with a telescopic spring 400 connected to the telescopic rod 301, which can drive the telescopic rod 301 to reset.

[0025] In this embodiment, preferably, a guide plate 500 is fixed to the top of the drive motor 101 to prevent material from accumulating on the top of the drive motor 101 during unloading.

[0026] In this embodiment, preferably, the dustproof mechanism includes a dustproof cover 600 sleeved on the top of the feed inlet 3, and rubber blocks 601 are symmetrically fixed on the inner wall of the dustproof cover 600, which can cover the feed inlet 3 to prevent dust.

[0027] The working principle and usage process of this utility model are as follows: When powder coating needs to be screened, the powder coating is first poured into the vibrating screen 2 through the feed inlet 3. The feed inlet 3 guides the powder coating at the top of the guide plate 500, preventing the powder coating from accumulating at the top of the drive motor 101. Then, the vibrating motor inside the base 1 is started to drive the vibrating screen 2 to vibrate and screen, and the drive motor 101 is started simultaneously, causing the shaft 102 to rotate at the top of the bearing seat 100, and causing the rotating rod 200 to rotate inside the vibrating screen 2, which in turn drives the scraper 201 to rotate synchronously. The rotating and pushing mechanism moves the clumps of powder coating, achieving the effect of stirring and dispersing. Simultaneously, when the scraper 201 is under pressure during rotation, the telescopic rod 301 slides inside the built-in groove 300, compressing the telescopic spring 400 and causing it to deform. This allows the scraper 201 to fit tightly against the bottom of the inner wall of the vibrating screen 2. The height of the scraper 201 can be adaptively adjusted as needed, making the sieving process more convenient. When not in use, the dust cover 600 can be fitted onto the top of the feed inlet 3, and the rubber block 601 acts as a compression limiter, thus covering the feed inlet 3 to prevent dust.

[0028] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
