Description

Technical Field

[0001] This utility model relates to the field of powder coating device technology, and in particular to a reciprocating sheet metal powder coating device. Background Technology

[0002] To improve the corrosion resistance of shelving, anti-corrosion materials (such as epoxy resin powder) are typically sprayed onto the sheet metal surfaces used for forming shelving shelves, back panels, and other components. Reciprocating sheet metal powder coating devices are suitable for spraying anti-corrosion materials onto sheet metal surfaces. For example, Chinese patent document CN217193040U discloses an online reciprocating electrostatic powder coating device with automatic powder recovery. This device includes a housing, symmetrically arranged side-mounted reciprocating linear modules on both sides of the housing, and spray guns connected to these modules. However, in the aforementioned online reciprocating electrostatic powder coating device, the spray guns connected to the side-mounted reciprocating linear modules are vertically distributed. When spraying epoxy resin powder onto the sheet metal surface, the spraying range of the spray guns is limited. The side-mounted reciprocating linear modules need to drive the spray guns to move back and forth multiple times to ensure that the sheet metal surface is evenly coated with epoxy resin powder, resulting in low powder coating efficiency.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] The present invention provides a reciprocating sheet metal powder coating device, which addresses the problem of low powder coating efficiency in existing online reciprocating electrostatic powder coating equipment.

[0005] To achieve the above objectives, the solution provided by this utility model is as follows: A reciprocating sheet metal powder coating device includes a powder coating chamber with an inlet and an outlet on the front and rear sides, respectively; a conveying track located below the top of the powder coating chamber; Z-axis linear modules symmetrically arranged on the left and right outer sides of the powder coating chamber; and a spray gun assembly connected to the moving end of the Z-axis linear modules. The left and right walls of the powder coating chamber each have openings for the spray gun assembly to move. The spray gun assembly includes: A movable support, which is connected to the movable end of the Z-axis linear module; A spray gun mounting rod is provided along the front-to-back direction of the powder spraying chamber and is connected to a movable bracket. The spray gun mounting rod has mounting holes spaced apart for the spray gun to pass through. A spray gun, wherein multiple spray guns are arranged horizontally and side by side, and the spray guns are vertically mounted on the spray gun mounting rod through the mounting holes; A locking screw is inserted into the spray gun mounting rod, and the locking screw extends into the mounting hole and abuts against the spray gun.

[0006] Optionally, the movable support includes: A movable rod is connected to the moving end of the Z-axis linear module, and the movable rod is parallel to the spray gun mounting rod; A connecting rod is perpendicular to the movable rod, and both ends of the connecting rod are connected to the movable rod and the spray gun mounting rod, respectively.

[0007] Optionally, the reciprocating sheet metal powder coating device further includes: A dust extraction pipe is connected to the top of the powder spraying chamber and is in communication with the powder spraying chamber. A bag filter dust collector, wherein the air inlet of the bag filter dust collector is connected to a dust extraction pipe; An induced draft fan is connected to the air outlet of the bag filter.

[0008] Beneficial effects: This invention provides a reciprocating sheet metal powder coating device. By setting a movable bracket connected to the moving end of a Z-axis linear module, and arranging multiple spray guns side-by-side on a spray gun mounting rod connected to the movable bracket, the coverage area of ​​a single powder coating is increased. This allows the moving end of the Z-axis linear module to drive the spray gun assembly up and down a smaller number of times, ensuring that the entire sheet metal surface is coated with epoxy resin powder. This improves powder coating efficiency and shortens powder coating time. To fix the spray guns to the spray gun mounting rod, this invention utilizes a locking screw. The locking screw extends into the mounting hole and abuts against the spray gun, thus preventing movement of the spray gun within the mounting hole due to the pressure from the locking screw.

[0009] Furthermore, since the spray gun mounting rod has multiple mounting holes spaced apart for the spray gun to pass through, the number of spray guns mounted on the spray gun mounting rod can be adjusted based on the width of the sheet metal to be powdered, so that the spray gun assembly provided by this utility model can adapt to the needs of powdering sheet metal of different widths.

[0020] Please see Figures 1 to 5 This utility model provides a reciprocating sheet metal powder coating device, including a powder coating chamber 1, a conveying track, a Z-axis linear module 2, and a spray gun assembly 3.

[0021] Specifically, the conveyor track (which may be the sprayed workpiece conveying system disclosed in CN208373391U) is prior art. Part of it is located below the inner top of the powder spraying chamber 1, and part of it is located outside the powder spraying chamber 1. Moreover, the front and rear sides of the powder spraying chamber 1 are respectively provided with an inlet 101 and an outlet 102. Thus, production personnel can hang the sheet metal to be sprayed with epoxy resin powder on the hook below the conveyor track outside the powder spraying chamber 1, and then the sheet metal is conveyed into the powder spraying chamber 1 through the inlet 101 via the conveyor track. After the sheet metal has completed the powder spraying operation in the powder spraying chamber 1, the sheet metal sprayed with epoxy resin powder is conveyed into the curing oven outside the powder spraying chamber 1 through the outlet 102 via the conveyor track.

[0022] Specifically, the Z-axis linear module 2 is symmetrically arranged on the left and right outer sides of the powder coating chamber 1, and the spray gun assembly 3 is connected to the moving end of the Z-axis linear module 2. The moving end of the Z-axis linear module 2 drives the spray gun assembly 3 to move up and down reciprocally, enabling the spraying of epoxy resin powder onto the sheet metal surface (it can be single-sided spraying, or simultaneous spraying of the front and back sides; during powder coating, the spray gun 33 of the spray gun assembly 3 is perpendicular to the front and back sides of the sheet metal suspended below the conveyor rail). The left and right walls of the powder coating chamber 1 are provided with openings 103 for the spray gun assembly 3 to move up and down, thus providing a channel for the spray gun assembly 3 to move vertically, allowing it to reciprocate under the drive of the Z-axis linear module 2.

[0023] Specifically, the spray gun assembly 3 includes a movable bracket 31, a spray gun mounting rod 32, a spray gun 33, and a locking screw 34. The movable bracket 31 is connected to the moving end of the Z-axis linear module 2. The spray gun mounting rod 32 is arranged along the front-rear direction of the powder spraying chamber 1 and is connected to the movable bracket 31. The spray gun mounting rod 32 has mounting holes 321 spaced apart for the spray guns 33 to pass through. The spray gun 33 can be an electrostatic spray gun, which can be connected to a high-voltage electrostatic generator. Multiple spray guns are arranged horizontally and side-by-side, and are vertically mounted on the spray gun mounting rod 32 through the mounting holes 321. This invention increases the coverage area of ​​a single powder spray by arranging multiple spray guns 33 side-by-side on the spray gun mounting rod 32. This allows the moving end of the Z-axis linear module 2 to drive the spray gun assembly 3 to move up and down less frequently, ensuring that the surface of the sheet metal is coated with epoxy resin powder. This improves powder spraying efficiency and shortens powder spraying time. In order to fix the spray gun 33 to the spray gun mounting rod 32, this utility model uses a locking screw 34, which extends into the mounting hole 321 and abuts against the spray gun 33, so that the spray gun mounting hole 321 is pressed by the locking screw 34 and cannot move.

[0024] Furthermore, since the spray gun mounting rod 32 has multiple mounting holes 321 at intervals for the spray guns 33 to pass through, the number of spray guns 33 installed on the spray gun mounting rod 32 can be adjusted based on the width of the sheet metal to be powdered, so that the spray gun assembly 3 provided by this utility model can adapt to the needs of powdering sheet metal of different widths.

[0025] like Figure 1 and Figure 5 As shown, optionally, two spray gun assemblies 3 positioned on the left and right sides of the powder coating chamber 1 form a group, and two or more groups of spray gun assemblies 3 can be set up. This can meet different powder coating process requirements, allowing multiple layers of anti-corrosion materials to be sprayed onto the sheet metal surface. Moreover, when multiple groups of powder coating assemblies are set up, if one group of powder coating assemblies needs maintenance, the other groups of powder coating assemblies can still be used, thus ensuring that the powder coating operation is not interrupted.

[0026] like Figures 2 to 4 As shown, optionally, the movable support 31 includes a movable rod 311 and a connecting rod 312.

[0027] Specifically, the movable rod 311 is connected to the moving end of the Z-axis linear module 2, and the movable rod 311 is parallel to the spray gun mounting rod 32; the connecting rod 312 is perpendicular to the movable rod 311, and both ends of the connecting rod 312 are connected to the movable rod 311 and the spray gun mounting rod 32 respectively. Through the connection of the connecting rod 312, the spray gun mounting rod 32 located inside the powder spraying chamber 1 can be connected to the moving end of the Z-axis linear module 2 outside the powder spraying chamber 1, ensuring that the spray gun assembly 3 can move up and down reciprocally under the drive of the Z-axis linear module 2. Furthermore, the layout of the movable rod 311 and the connecting rod 312 allows the spray gun mounting rod 32 to be set to a relatively long length within the powder spraying chamber 1, and the number of spray guns 33 on the spray gun mounting rod 32 can be flexibly adjusted based on the width of the sheet metal to be powdered.

[0028] like Figure 1 As shown, optionally, the reciprocating sheet metal powder coating device further includes a dust extraction pipe 6, a bag filter 7, and an induced draft fan 8. Specifically, the dust extraction pipe 6 is connected to the top of the powder coating chamber 1 and communicates with the powder coating chamber 1; the air inlet of the bag filter 7 is connected to the dust extraction pipe 6; and the induced draft fan 8 is connected to the air outlet of the bag filter 7.

[0029] During the powder coating process, a large amount of dust is generated in the powder coating chamber 1. This dust can easily drift from the inlet 101 and outlet 102 of the powder coating chamber 1 to the workshop outside the powder coating chamber 1, which not only wastes epoxy resin powder but also deteriorates the workshop environment outside the powder coating chamber 1. Therefore, during the powder coating process, the induced draft fan 8 is turned on so that the dust extraction pipe 6 can suck in the dust in the powder coating chamber 1 and filter and collect the dust through the bag filter. This allows the bag filter dust collector 7 to effectively intercept the dust, and the purified air is discharged under the action of the induced draft fan 8, reducing the dust concentration in the workshop.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
