Description

Technical Field

[0001] This utility model relates to the technical field of powder coating processing equipment, and in particular to a powder collection device for a powder coating outlet. Background Technology

[0002] Powder coating is a new type of solvent-free solid powder coating. It is made by mixing film-forming resin, additives, pigments and fillers, followed by crushing and sieving. It requires electrostatic spraying combined with baking process to complete the coating film formation. It is solvent-free and recyclable, and has both environmental protection and resource-saving characteristics. It performs outstandingly in terms of energy saving, environmental protection and construction performance.

[0003] In the production and sales of powder coatings, it is often necessary to first conduct sample prototyping in the laboratory. However, existing small-capacity high-speed mixers used for laboratory prototyping lack dust prevention mechanisms during powder collection at the powder outlet. As is well known, inhaling powder coating dust can cause respiratory irritation or long-term lung disease. In addition, the spread of powder coating dust in the laboratory can contaminate other experimental areas and affect experimental results. Furthermore, powder coating dust reaching a certain concentration in the air may trigger a dust explosion, posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a powder collection device for a powder coating outlet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A powder collection device for a powder coating outlet, characterized in that it includes a high-speed mixer, a mixing hopper disposed on top of the high-speed mixer, a bottom-mounted drive motor unit fixedly connected to the center of the bottom surface of the mixing hopper, a hinged hopper cover disposed on the top edge of the mixing hopper, a discharge channel fixedly disposed on the bottom edge of the mixing hopper, a manual discharge door fixedly disposed at the inlet of the discharge channel, and a receiving hopper.

[0007] The discharge channel includes a discharge port; the discharge port is detachably fitted with a first dustproof cloth and a second dustproof cloth that are vertically connected; the first dustproof cloth is located outside the second dustproof cloth; the first dustproof cloth has several deformable metal strips arranged in a vertical circumferential array.

[0008] In use, the first dustproof cloth, supported by the deformable metal strip, completely covers the opening of the receiving hopper and adheres to the outside of the hopper, while the second dustproof cloth is completely placed inside the receiving hopper. When material is discharged from the outlet, the second dustproof cloth forms a flexible guide channel inside the hopper, guiding the powder to slide down the cloth surface to the bottom of the hopper, reducing the impact and scattering of the powder as it falls. Some dust will be stirred up; this stirred-up dust is first blocked by the flexible inner side of the second dustproof cloth. Then, the first dustproof cloth, with the elastic support of the deformable metal strip and its naturally drooping bottom, can dynamically conform to the outer wall of the receiving hopper, together forming an outer dustproof space, effectively intercepting some of the dust that escapes from the second dustproof cloth.

[0009] Preferably, the discharge port is provided with a snap-fit ​​groove and a snap-fit ​​clamp that matches the snap-fit ​​groove, and the snap-fit ​​clamp is engaged with the snap-fit ​​groove for limiting engagement; the first dustproof cloth and the second dustproof cloth are both engaged between the snap-fit ​​groove and the snap-fit ​​clamp, and the first dustproof cloth and the second dustproof cloth can be quickly installed and removed.

[0010] Preferably, the clamp includes a threaded connection notch; the connection notch includes a nut fixedly disposed at one end of the clamp and a butterfly locking bolt disposed at the other end of the clamp, and the clamp is limited and clamped in the clamping groove by the threaded connection between the nut and the butterfly locking bolt, and the first dustproof cloth and the second dustproof cloth are clamped stably.

[0011] Preferably, the first dustproof cloth and the second dustproof cloth are integrally molded and connected to eliminate the risk of leakage at the seam, extend the service life, and reduce long-term use costs.

[0012] Compared with the prior art, the powder collection device for the powder outlet of the powder coating of this application has the following advantages:

[0013] 1. Dual Dustproof Structure Working Together to Effectively Suppress Dust Escape: A nested design of the first and second dustproof cloths creates a dual dynamic sealing barrier. When powder flows into the receiving hopper through the second dustproof cloth, the stirred-up dust is first blocked by the flexible inner side of the second cloth. Meanwhile, the first dustproof cloth, supported by a deformable metal strip, and its naturally drooping bottom, dynamically conforms to the outer wall of the receiving hopper, forming an outer dustproof space. This synergistic effect significantly reduces the probability of dust escaping from the receiving hopper opening, effectively preventing operators from inhaling harmful dust, while also preventing laboratory environment contamination and ensuring the accuracy of experimental results.

[0014] 2. The adjustable sealing structure offers strong adaptability and a high level of safety protection: The deformable metal strips in the circumferential array of the first dustproof cloth can adaptively deform according to the outer diameter of the receiving hopper, ensuring that receiving hoppers of different sizes can be attached to the outside of the hopper. Combined with the second dustproof cloth hanging inside the hopper, a three-dimensional dustproof system with two-way wrapping is formed, keeping the dust concentration below the explosion threshold at all times, eliminating the risk of dust explosion at its source.

[0015] 3. Modular quick-release design improves maintenance efficiency: The dust cover assembly can be quickly installed and removed via a snap-fit ​​groove and a snap-fit ​​clamp with a butterfly locking bolt. Operators can replace or clean the dust cover without tools, avoiding the time-consuming maintenance issues associated with traditional bolt fastening. The one-piece molded dust cover structure further eliminates the risk of leakage at seams, extends service life, and reduces long-term operating costs.

[0016] 4. Integrated flow guidance and sealing functions optimize collection efficiency: The second dustproof cloth forms a flexible flow guidance channel on the inside of the bucket, guiding the powder to slide down the cloth surface to the bottom of the bucket, reducing the impact and flying of the powder when it falls; at the same time, its natural hanging shape at the bottom can dynamically fit the surface of the accumulated powder, forming an adaptive sealing layer that rises with the material level, further improving the dustproof effect while ensuring the integrity of powder collection and reducing raw material waste.

[0017] In summary, this device, through its innovative double-layer dynamic sealing mechanism, adaptive deformation structure, and modular quick-release design, systematically solves the dust problem that exists when discharging powder from a small-capacity laboratory mixer, and has significant practical value and prospects for promotion.

Then, the first dustproof cloth 52, with the elastic support of the deformable metal strip 54, and its natural hanging shape at the bottom, can dynamically fit against the outer wall of the receiving barrel 7, together forming an outer dustproof space, effectively intercepting some of the dust that escapes from the second dustproof cloth 53.
