Description

Technical Field

[0001] The present application relates to the technical field of plastic spraying equipment, and specifically to a dust collection device. Background Art

[0002] Powder coating refers to a process for treating industrial metal surfaces. Powder coating is a new type of solvent-free, 100% solid powder coating. There are two main categories of coatings: thermoplastic powder coatings and thermosetting powder coatings. These coatings are made by mixing specialized resins, pigments, fillers, curing agents, and other additives in a specific proportion, then preparing them through processes such as hot extrusion, crushing, and screening. They are stable at room temperature and are applied through electrostatic spraying or fluidized bed dipping, followed by heating and baking to melt and solidify, forming a smooth, glossy, permanent coating that achieves both decorative and corrosion protection. During the spraying process, airborne powder recovery is required to improve coating utilization, contribute to environmental protection, and control costs.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] like Figure 1-Figure 2 As shown, the present application provides a dust collection device, including a spraying mechanism 1, which is arranged in a processing workshop of a factory. The spraying mechanism 1 includes a spraying chamber 11, and a receiving chamber is provided in the spraying chamber 11. At the same time, a robotic arm 12 is provided in the receiving chamber, and a spraying head is installed on the robotic arm 12 for spraying the material. At the same time, a loading assembly 2 is provided on one side of the robotic arm 12, and the loading assembly 2 is used to place the material and move the material into the spraying chamber 11 so that the material can be accurately sprayed by the robotic arm 12;

[0025] A notch is provided on one side of the bottom of the spraying chamber 11, and a material blocking curtain is installed on the notch. At the same time, the loading assembly 2 includes a rotating table 21, which is fixedly installed at the notch of the spraying chamber 11. At least two sets of placement tables 22 are fixedly installed on the outside of the rotating table 21. The placement tables 22 are used to place materials to be sprayed, and when one set of placement tables 22 is located inside the spraying chamber 11, the other set of placement tables 22 is located outside the spraying chamber 11;

[0026] When spraying is required, the material is first placed on the top of the placement table 22, and then the rotating table 21 is started, so that the material on the placement table 22 is sent into the spraying chamber 11. At this time, the gap at the notch will be blocked by the material blocking curtain, so that dust will not be sprayed out. At the same time, the staff can place the next batch of materials on another set of placement tables 22 and wait for the next feeding.

[0027] In order to enable the powder dropped during the spraying process to be recovered in time, improvements are made to the placement table 22, specifically:

[0028] like Figure 2-Figure 4 As shown, the interior of the placement platform 22 is set to be hollow, and a mounting plate 23 is set on the top of the placement platform 22. The mounting plate 23 is provided with multiple groups of leakage holes that communicate with the interior of the placement platform 22. When spraying, excess powder will enter the interior of the placement platform 22 through the leakage holes. A discharge pipe 24 is provided at the bottom of the placement platform 22. The discharge pipe 24 is used to recover the dust inside the placement platform 22.

[0029] At the same time, a collecting mechanism 3 is provided on the side of the spraying chamber 11 away from the feeding assembly 2. The collecting mechanism 3 includes a fan 31, which is fixedly installed on one side of the spraying chamber 11. At the same time, a first conveying pipe 32 is fixedly installed on the top of the fan 31. The end of the first conveying pipe 32 away from the fan 31 passes through the top of the spraying chamber 11, and is used to recover the dust floating in the spraying chamber 11.

[0030] At the same time, a second material delivery pipe 33 is provided on one side of the first material delivery pipe 32. The end of the second material delivery pipe 33 away from the fan 31 passes through the spraying chamber 11. The end of the second material delivery pipe 33 is a corrugated pipe whose length can be freely changed. At the same time, a connecting component 4 is provided in the spraying chamber 11. The connecting component 4 includes a cylinder 41. A connecting plate 42 is fixedly installed on the output end of the cylinder 41. The interior of the connecting plate 42 is hollow, and one side of the connecting plate 42 is connected to the second material delivery pipe 33. At the same time, a drawing pipe 43 is provided on the top of the connecting plate 42. A mounting groove is provided on the top of the drawing pipe 43. The size of the mounting groove is adapted to the discharge pipe 24, so that the discharge pipe 24 is suitable for being connected to the drawing pipe 43.

[0031] At the same time, in order to make the connection between the discharge pipe 24 and the extraction pipe 43 tighter, a sealing ring 5 is provided on the outside of the discharge pipe 24. The sealing ring 5 is used to increase the sealing performance of the discharge pipe 24 and the extraction pipe 43, so that when the fan 31 recovers the dust in the placement table 22, the dust will not leak from the connection.

[0032] When the material enters the spraying chamber 11 through the rotating table 21, the connecting plate 42 is pushed upward by controlling the cylinder 41, so that the extraction pipe 43 is connected to the discharge pipe 24 at the bottom of the placement table 22, and then the fan 31 is turned on, so that the fan 31 can simultaneously recover the powder floating in the spraying chamber 11 and the powder in the placement table 22, thereby increasing the dust recovery efficiency.

[0033] In summary, by providing the collection mechanism 3, the device enables the dust generated during the spraying process to be immediately recovered and processed, which not only helps to keep the working environment clean, but also improves production efficiency and reduces the potential impact of dust on operations and equipment.

[0034] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
