The annular powder coating setup improves the utilization rate of the production workshop.

Description

Technical Field

[0001] This invention relates to the field of shell powder coating equipment, and particularly to a diesel filter shell powder coating equipment. Background Technology

[0002] Diesel fuel filters are key components in diesel engine fuel systems. They are mainly used to filter impurities and water from the fuel and protect precision components such as fuel injection pumps and nozzles from wear.

[0003] The existing diesel filter housing powder coating equipment mainly works on the principle of electrostatic powder coating. The high-voltage electrostatic generator at the front end of the spray gun generates corona discharge, which charges the powder coating particles. Under the action of the electric field, the charged powder particles are attracted to the grounded diesel filter housing surface. The corrosion resistance (resistance to water vapor, grease and other erosion) and high adhesion of the powder coating process are particularly suitable for the protection needs of diesel filter housings, and can effectively solve the problem of traditional carbon steel housings being prone to rust.

[0004] In summary, existing diesel filter housing powder coating devices typically employ an assembly line operation method. The powder coating production line is designed to be quite long, resulting in a large footprint. During the powder coating process, diesel filter housings need to be arranged and sprayed sequentially. This serial operation mode not only increases the length of the production line but also requires sufficient space to accommodate spraying equipment, conveying devices, and curing equipment. This limits the space utilization rate of the production workshop, and is particularly unsuitable for the site conditions of small and medium-sized manufacturers. Summary of the Invention

[0005] This invention provides a diesel filter housing powder coating equipment, which solves the problem that existing diesel filter housing powder coating devices usually adopt an assembly line operation mode. The powder coating production line design is long, resulting in a large equipment footprint. During the powder coating process, the diesel filter housings need to be arranged and sprayed sequentially. This serial operation mode not only increases the length of the production line, but also requires sufficient space to be reserved for the spraying equipment, conveying devices, and curing equipment, which limits the space utilization rate of the production workshop, especially the poor site adaptability of small and medium-sized manufacturers.

[0006] A diesel filter housing powder coating equipment includes a powder coating box assembly for isolating the spraying area, a shifting component for moving the diesel filter housing to a different position is provided at the bottom of the inner cavity of the powder coating box assembly, and a conveying component for feeding and discharging materials is provided on the side of the powder coating box assembly. Preferably, the powder-coated box assembly includes an isolation box, the bottom of the inner cavity of the isolation box is provided with a first sliding groove, the center of the first sliding groove is provided with an annular groove, and an air processor is provided on the top of the isolation box.

[0014] Beneficial effects: 1. In this invention, when the irregular gear slides inside the first slide groove to the connection between the first slide groove and the annular groove, the electromagnetic block is energized to generate a magnetic field. Under the action of the magnetic field, the first slide groove and the annular groove are connected. The roller structure symmetrically arranged at both ends of the bottom of the irregular gear first enters the first slide groove. After the electromagnetic block is de-energized and reset, the other roller continues to move along the trajectory of the annular groove, thereby realizing the simultaneous revolution and rotation of the irregular gear.

[0016] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0017] like Figures 1 to 5 As shown, an embodiment of the present invention provides a diesel filter housing powder coating equipment, including a powder coating box assembly 1 for isolating the spraying area, a shifting assembly 2 for driving the diesel filter housing to shift position is provided at the bottom of the inner cavity of the powder coating box assembly 1, and a conveying assembly 3 for feeding and discharging materials is provided on the side of the powder coating box assembly 1. The powder coating box assembly 1 includes an isolation box 11. The bottom of the inner cavity of the isolation box 11 is provided with a first sliding groove 15, and an annular groove 16 is provided at the center of the first sliding groove 15. An air processor 110 is provided on the top of the isolation box 11, and a drive motor is provided on the bottom of the isolation box 11 to drive the drive gear 21 to rotate and provide power to the drive gear 21. The air processor 110 is used to remove moisture, oil and particulate matter from the compressed air through components such as an oil-water separator and an air tank. If the compressed air contains impurities, it will cause defects such as blistering, particles or fish eyes in the coating. The air processor 110 provides a constant air pressure to the spray gun 17, which directly affects the atomization degree and spray uniformity of the paint and can match the spraying requirements of paints with different viscosities.

[0018] The shifting assembly 2 includes a drive gear 21, around which are arranged an array of dissimilar gears 22 for shifting the outer casing. Support rods 24 are arranged on top of the dissimilar gears 22, and a conical platform 25 for fixing the outer casing is fixedly connected to the top of the support rods 24. One end of the conical platform 25 has a flat surface. The conveying assembly 3 includes a gear 31, with a chain 32 meshing on its surface. A cross-shaped positioning plate 33 for limiting the position is fixedly connected to the back of the chain 32. A placement rod 34 is connected in series with the cross-shaped positioning plate 33 on the front of the chain 32. The drive gear 21 drives the dissimilar gears 22 arranged around it to rotate. When the dissimilar gears 22 rotate inside the first slide groove 15 to the corner of the first slide groove 15, the electromagnetic block 23 is energized to generate a magnetic field. Since a magnet is provided at one end of the limiting groove 150 at the corner of the first slide groove 15, the electromagnetic block 23 is a device that converts electrical energy into mechanical energy. Its core working principle is based on the magnetic effect of electric current. When current passes through the winding... When the coil is coiled on the iron core, a magnetic field is generated around the coil. After the iron core is magnetized, it is superimposed with the magnetic field of the coil to form a strong magnet. When energized, the iron core (or plunger) is attracted to the center of the magnetic field, which drives the mechanical parts to move. After the power is cut off, the magnetism disappears and the iron core is reset under the action of the spring. When the electromagnetic block 23 is energized, a magnetic field is generated, which causes the interior of the limiting groove 150 at one end of the electromagnetic block 23, where the guide slope 230 is set, to deflect, so that the first slide groove 15 and the annular groove 16 are connected. After one of the rollers symmetrically arranged at both ends of the bottom of the drive gear 21 enters the interior of the first slide groove 15, the electromagnetic block 23 is immediately de-energized. Under the reset action of the torsion spring set in the middle connection part of the electromagnetic block 23 and the limiting groove 150, the guide slope 230 is reset again and forms an annular track structure with the annular groove 16, so that the roller at the other end of the bottom of the heterogeneous gear 22 still moves along the trajectory of the annular groove 16, thereby realizing the revolution of the heterogeneous gear 22 and its rotation at the same time, which facilitates the spray gun 17 to spray paint the shell at multiple angles.

[0019] A limiting groove 150 is provided at one end of the first slide 15. An electromagnetic block 23 for adjusting the moving direction of the heterogeneous gear 22 is movably connected inside the limiting groove 150. A guide slope 230 is provided at one end of the electromagnetic block 23. The arc surface of the guide slope 230 has the same curvature as part of the arc surface of the annular groove 16. The arc surface of the guide slope 230 can complete the connection between the annular groove 16 and the first slide 15, making the annular groove 16 a complete circular track structure. A magnet is provided inside the limiting groove 150 near the corner, which is used to change the sealing effect of the guide slope 230 on one end of the first slide 15 after the electromagnetic block 23 is energized. The side of the conical platform 25 with the slope always remains opposite to the storage rod 34 when the heterogeneous gear 22 rotates to the side of the discharge port 12 and the inlet port 13.

[0020] The adjacent sides of the isolation box 11 are respectively provided with a discharge port 12 and a feed port 13. Both the discharge port 12 and the feed port 13 are slidably connected to the outside of a partition plate 14. The adjacent sides of the inner cavity of the isolation box 11 without the discharge port 12 and the feed port 13 are provided with spray guns 17 for powder coating. The sides of both the discharge port 12 and the feed port 13 are provided with second sliding grooves 18. Both ends of the second sliding groove 18 are provided with clearance grooves 111. Limit blocks 19 are provided on both sides of the second sliding groove 18. The surface of the limit blocks 19 has protrusions 190. The outer shell to be powder coated moves to one side of the feed port 13 via a placement rod 34 provided inside the feed port 13. When the conical platform 25 on the top of the gear 22 is parallel to the storage rod 34, the storage rod 34 hangs the outer shell on the top of the conical platform 25 under the rotation of the chain 32. At this time, the chain 32 rotates clockwise. When it is necessary to transport the powder-coated outer shell outward, the storage rod 34 inside the discharge port 12 rotates counterclockwise with the chain 32. The storage rod 34 drives the outer shell to move upward from below the conical platform 25 and detach it from the top of the conical platform 25. Since the side of the conical platform 25 has a plane to avoid interference with the storage rod 34, the outer shell can be smoothly detached from the conical platform 25.

[0021] A first roller 330 is provided horizontally on the cross positioning plate 33, and a second roller 331 is provided vertically on the cross positioning plate 33. A limiting block 19 is used to maintain the vertical state of the cross positioning plate 33 when it slides inside the second slide groove 18. The length of the first roller 330 is greater than the length of the second roller 331. The clearance groove 111 is flush with the protrusion 190. The portion of the clearance groove 111 near the gear 31 has symmetrically arranged arc-shaped structures communicating with the second slide groove 18. Driven by the chain 32, the cross positioning plate 33 slides within the second slide groove 18... The internal movement is elliptical. The first rollers 330 at both ends of the cross positioning plate 33 can limit the cross positioning plate 33 in the horizontal direction when sliding through the limiting block 19, preventing the outer shell on one end of the placement rod 34 from tilting and slipping. The height misalignment of the first rollers 330 and the second rollers 331 allows the second rollers 331, which are perpendicular to the cross positioning plate 33, to be close to the side wall of the second slide groove 18 and the side of the protrusion 190 when the cross positioning plate 33 moves, thus limiting the cross positioning plate 33 in the vertical direction and keeping the outer shell in the same state during the conveying process.

[0022] Working principle: When powder coating is required, the outer shell is moved through the feeding port 13 and the conical platform 25 on top of the irregular gear 22 is parallel to the feeding port 13. Under the rotation of the chain 32, the feeding rod 34 hangs the outer shell on the top of the conical platform 25. The drive gear 21 drives the irregular gears 22 arranged around it to rotate. When the irregular gears 22 rotate inside the first slide groove 15 to the corner of the first slide groove 15, the electromagnetic block 23 is energized to generate a magnetic field. The magnetic field generated after energization causes the inner end of the limit groove 150 of the electromagnetic block 23, which is provided with the guide slope 230, to deflect, so that the first slide groove 15 and the annular groove 16 are connected. One of the rollers symmetrically arranged at both ends of the bottom of the drive gear 21 enters the first slide groove 15. Afterwards, the electromagnetic block 23 is immediately de-energized. Under the reset action of the torsion spring set in the middle connection part between the electromagnetic block 23 and the limiting groove 150, the guide slope 230 is reset again to form an annular track structure with the annular groove 16. This allows the roller at the other end of the bottom of the heterogeneous gear 22 to continue moving along the trajectory of the annular groove 16, thereby realizing the heterogeneous gear 22's revolution and rotation at the same time. This facilitates the spray gun 17 to spray paint the shell at multiple angles. After the shell is sprayed, the placement rod 34 set inside the discharge port 12 moves upward from below the conical placement platform 25 and separates from the top of the conical placement platform 25 under the counterclockwise rotation of the chain 32. Since the side of the conical placement platform 25 has a plane to avoid interference with the placement rod 34, the shell can be smoothly separated from the conical placement platform 25.

[0023] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
