Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, specifically to a powder coating device for the production of aluminum alloy powder coated profiles. Background Technology

[0002] The powder coating equipment for aluminum alloy profile production is a specialized device that uses the principle of electrostatic adsorption to uniformly spray dry powder coating onto the surface of aluminum alloy profiles, and then cures it at high temperature to form a strong and beautiful coating.

[0003] Existing powder coating equipment mostly uses fixed powder hoppers for feeding. Whenever it is necessary to change the powder color or type, the machine must be stopped and the entire powder supply system must be cleaned. This process is cumbersome and time-consuming, leading to frequent production interruptions. At the same time, powder is prone to accumulating and clogging in stationary conveying pipes. This not only requires machine shutdown for cleaning, affecting production continuity, but also causes uneven coating. This makes it difficult for existing equipment to meet the requirements of high-efficiency and continuous production. Utility Model Content

[0004] The purpose of this utility model is to provide a powder coating device for the production of aluminum alloy sprayed profiles, which solves the problems of low production efficiency and continuity.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a powder coating device for the production of aluminum alloy sprayed profiles, including a support structure, on which a rotatable drive plate is provided, and multiple positioning rings for positioning loading tanks are provided on the drive plate along the circumferential direction.

[0007] The positioning ring is provided with a loading tank, which includes an outer loading tank. The outer loading tank is provided with a retractable loading drawer, and the loading drawer is provided with a drawer handle on the outside.

[0008] A paint spraying pipe is connected above the loading outer tank. The paint spraying pipe includes a paint spraying conduit that communicates with the loading outer tank and is connected to a paint spraying connector.

[0009] A driven permanent magnet is provided on the outer peripheral wall of the paint spraying nozzle;

[0010] The device further includes a magnetic drive structure comprising a rotatable active permanent magnet, the active permanent magnet being magnetically coupled to the driven permanent magnet.

[0011] Furthermore, the end of the paint spraying conduit is provided with a connecting thread;

[0012] The inner rear end of the paint spraying nozzle is provided with a thread that mates with the connecting thread, and a bonding rubber is also embedded in the inner rear end of the paint spraying nozzle. The bonding rubber and the connecting thread are tightly engaged to form a sealed connection.

[0013] Furthermore, a Venturi pump is provided above the outer loading tank of the loading tank, and the outlet of the Venturi pump is connected to the paint spraying conduit.

[0014] Furthermore, the magnetic drive structure also includes a magnetic drive motor;

[0015] The output shaft of the magnetic drive motor is connected to a drive shaft, and a drive gear is provided on the drive shaft;

[0016] The driving gear meshes with the driven gear, and there are six driving permanent magnets arranged in a ring on the inner wall of the central hole of the driven gear.

[0017] Furthermore, the support structure comprises a six-circular array of support columns;

[0018] A support plate is connected above the support column, and the drive plate is driven to rotate by a rotating motor located below the support plate and connected to its center.

[0019] Furthermore, there are six positioning rings and six loading tanks, arranged in a circular array on the drive plate.

[0020] This utility model has the following beneficial effects:

[0021] (1) This utility model constructs a multi-station powder supply system by setting a rotatable drive plate driven by a rotating motor, and arranging multiple positioning rings and loading tanks in a circular array on it. When it is necessary to change the powder color, the system does not need to be stopped. It only needs to start the rotating motor to rotate the next pre-loaded loading tank to the working position to immediately resume powder supply. This completely avoids the frequent production interruptions caused by stopping the entire powder supply system to clean up in the prior art, and greatly improves production efficiency and continuity.

[0022] (2) This utility model uses a unique magnetic drive design. The magnetic drive motor drives the driven gear and the active permanent magnet of the inner wall ring array to rotate through the drive shaft and the active gear. The magnetic field coupling drives the paint spray pipe and the driven permanent magnet on it to rotate continuously and slowly. This rotational motion prevents the powder from being stationary and deposited on the inner wall of the pipe, thus effectively solving the problem that the powder is easy to be deposited and blocked in the stationary conveying pipe in the prior art, which leads to the need to stop the machine for cleaning and uneven spraying.

[0023] (3) The connection between the paint spraying conduit and the paint spraying nozzle of this utility model adopts a mechanical connection between the connecting thread and the inner thread of the rear end of the paint spraying nozzle, and innovatively embeds a bonding rubber inside the paint spraying nozzle. The bonding rubber and the connecting thread are tightly engaged to form a reliable dynamic seal, which not only ensures the sealing performance in the rotating state and prevents powder leakage, but also makes the connector easy to disassemble and maintain, solving the potential problems of poor sealing or inconvenient maintenance at the connection in the prior art.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Please see Figures 1-5 As shown, this utility model is a powder coating device for the production of aluminum alloy sprayed profiles, including a support structure 1, a rotatable drive plate 13 is provided on the support structure 1, and a plurality of positioning rings 15 for positioning the loading tank 2 are provided on the drive plate 13 along the circumferential direction.

[0035] The support structure 1 includes six circular arrays of support columns 11;

[0036] A support plate 12 is connected above the support column 11, and the drive plate 13 is driven to rotate by the rotating motor 14 below the support plate 12, which is connected to the central shaft.

[0037] There are six positioning rings 15 and six loading tanks 2, which are arranged in a circular array on the drive rotating plate 13.

[0038] When the powder needs to be replaced, the rotating motor 14 is started, driving the rotating shaft that runs through the support plate 12, thereby driving the rotating plate 13 to rotate precisely on the support structure 1 which is stably supported by six support columns 11. The rotation of the rotating plate 13 causes the six positioning rings 15 arranged around it to move synchronously, thereby rotating the idle loading tank 2 containing new powder in one of the positioning rings 15 to the working position to replace the original loading tank 2, while the loading tank 2 in the original position is rotated to other positions for replacement or cleaning.

[0039] The positioning ring 15 is provided with a loading tank 2, which includes an outer loading tank 21. The outer loading tank 21 is provided with a pull-out loading drawer 22, and the outside of the loading drawer 22 is provided with a drawer handle 23.

[0040] A Venturi pump 24 is provided above the outer loading tank 21 of the loading tank 2, and the outlet of the Venturi pump 24 is connected to the paint spraying conduit 31;

[0041] Among them, the Venturi pump 24 is an air pump, please refer to the patent number "CN112610539A Venturi air pump" for details;

[0042] When the device is working, the Venturi pump 24 located above the loading outer tank 21 generates negative pressure, which draws out the powder stored in the pull-out loading box 22 and delivers it directly to the paint spraying conduit 31 connected thereto, thereby providing a continuous supply of powder for spraying. When it is necessary to change the powder type or replenish the powder, the operator can easily pull out the entire loading box 22 from the loading outer tank 21 for replacement or cleaning through the box handle 23 provided on the outside of the loading box 22 without touching other parts.

[0043] A paint spraying pipe 3 is connected above the loading outer tank 21. The paint spraying pipe 3 includes a paint spraying conduit 31 that communicates with the loading outer tank 21 and is connected to the paint spraying connector 33.

[0044] A driven permanent magnet 35 is provided on the outer peripheral wall of the paint spraying nozzle 33;

[0045] The end of the paint spraying conduit 31 is provided with a connecting thread 32;

[0046] The inner rear end of the paint spraying connector 33 is provided with a thread that mates with the connecting thread 32, and the inner rear end of the paint spraying connector 33 is also embedded with a bonding rubber 34. The bonding rubber 34 and the connecting thread 32 are tightly engaged to form a sealed connection, and a spray gun is also connected to the rear end of the paint spraying connector 33.

[0047] For details regarding the spray gun, please refer to patent number "CN1165381 C Powder Spray Gun";

[0048] After the powder is delivered into the paint spraying tube 31 of the paint spraying tube 3 by the Venturi pump 24, it flows through its end and enters the paint spraying connector 33 through the connecting thread 32. At this connection, the bonding rubber 34 embedded in the inner side of the rear end of the paint spraying connector 33 is tightly engaged with the connecting thread 32 to ensure the sealing of the connection. At the same time, the driven permanent magnet 35 installed on the outer peripheral wall of the paint spraying connector 33 drives the entire paint spraying connector 33 to rotate continuously and slowly under the drive of the external magnetic field.

[0049] The device also includes a magnetic drive structure 4, which includes a rotatable active permanent magnet 41 and a driven permanent magnet 35 magnetically coupled.

[0050] The magnetic drive structure 4 also includes a magnetic drive motor 45;

[0051] The output shaft of the magnetic drive motor 45 is connected to a drive shaft 44, and a drive gear 43 is provided on the drive shaft 44;

[0052] The driving gear 43 meshes with the driven gear 42, and there are six driving permanent magnets 41 arranged in a ring on the inner wall of the central hole of the driven gear 42.

[0053] When the paint spray nozzle 33 needs to be rotated, the magnetic drive motor 45 starts, and its output shaft drives the drive shaft 44 and the active gear 43 fixed thereon to rotate together. The active gear 43 meshes with the driven gear 42, so that the six active permanent magnets 41 arranged in a ring on the inner wall of the central hole of the driven gear 42 synchronously generate circular motion. The rotating active permanent magnets 41 transmit torque through space by non-contact magnetic coupling with the driven permanent magnets 35 fixed on the outer wall of the paint spray nozzle 33, thereby driving the paint spray nozzle 33 to rotate continuously on its axis.

[0054] In use, the operator first pushes the loading box 22 containing the specific color powder into the loading outer tank 21 through the box handle 23, assembling the complete loading tank 2. It is then placed in the positioning ring 15 of the drive rotating plate 13 above the support structure 1, which consists of the support column 11 and the support plate 12. When spraying needs to be started, the rotating motor 14 drives the drive rotating plate 13 to rotate, switching the target loading tank 2 to the working position. At this time, the Venturi pump 24 on top of the loading tank 2 at this position starts working, drawing the powder from the loading box 22 and conveying it to the spraying conduit 31 of the spray pipe 3. The powder then flows into the spray pipe 33, which is connected to the end of the spraying conduit 31 via the connecting thread 32. The connecting rubber 34 here ensures the sealing of the connection. Meanwhile, to prevent powder deposition, the magnetic drive structure 4 opens... Initial operation: The magnetic drive motor 45 starts, driving the drive shaft 44 and the drive gear 43 to rotate. The drive gear 43 drives the driven gear 42 to rotate, thereby causing the six active permanent magnets 41 in the ring array in the center hole of the driven gear 42 to rotate synchronously. The rotating active permanent magnets 41 are magnetically coupled with the driven permanent magnets 35 fixed on the outer wall of the paint spraying pipe 33, driving the entire paint spraying pipe 33 to rotate slowly without contact. Finally, under the combined action of the high-pressure airflow and the rotating pipe, the powder is evenly sprayed out from the spray gun at the end of the paint spraying pipe 33. When it is necessary to change the color, the system does not need to stop. The rotating motor 14 starts again, and the rotating drive plate 13 rotates the next loading tank 2 into the working position. The loading box 22 that has just been used can be directly pulled out for cleaning, thereby realizing high-efficiency and continuous production.
