Description

Technical Field

[0001] The present invention particularly relates to a powder line solidification online circulating air-ice-water cooling device. Background Art

[0002] In surface treatment processes, powder coating (powder coating) technology is widely used for surface coating of metal, plastic, and other workpieces due to its environmental friendliness, high adhesion, and uniform coating results. The core steps of the powder coating process include workpiece pretreatment, electrostatic spraying, high-temperature curing, and cooling and forming. The cooling and curing stage has a decisive influence on the coating's final properties (such as hardness, gloss, and weather resistance) and production efficiency.

[0003] Traditional cooling processes often rely on natural cooling or fixed air cooling devices. Natural cooling takes a long time, extending production cycles. While fixed air cooling can shorten cooling time, the airflow direction and workpiece position are relatively static, which can easily lead to the following problems: 1. In complex workpieces (such as porous and special-shaped parts), grooves and gaps cannot be effectively covered by airflow, resulting in slow heat dissipation, which may cause uneven coating shrinkage, microcracks, or orange peel phenomenon. 2. Flat areas are overcooled due to continuous wind exposure, creating temperature differential stress with slower-cooling areas, reducing coating adhesion.

[0004] In existing technologies, workpieces are typically kept static during the cooling phase (e.g., Chinese Patent Publication No. CN109876982A) and moved horizontally at a constant speed via a conveyor belt (e.g., Chinese Patent Publication No. CN109876982A). This approach fails to dynamically match the airflow to the workpiece surface, limiting cooling effectiveness and efficiency, particularly when processing vertically suspended workpieces or workpieces requiring multi-sided coating. Consequently, internal stresses caused by differential cooling rates across different regions of the material can lead to coating deformation or cracking. Summary of the Invention

Of course, these are merely examples or embodiments and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the different embodiments and / or configurations discussed.

[0032] like Figures 1 to 6The powder line solidification online circulating air-ice water cooling device shown in the figure comprises: a cooling chamber 1, with a material feeding inlet 2 and a material feeding outlet 3 respectively passing through the two sides thereof; a conveying device, which passes through the material feeding inlet 2 and the material feeding outlet 3, and comprises a conveying track 4 and a hanging member 5 movably arranged on the conveying track 4, and a first driving member 6 capable of driving the hanging member 5 to move along the length direction of the conveying track 4; the hanging member 5 comprises a fixed rod 51 movably arranged on the conveying track 4, and a first movable rod 52 movably arranged on the fixed rod 51, the lower end of the first movable rod 52 is provided with a The hook 53 for hanging the workpiece has a push rod 54 on one side of the first movable rod 52; the second driving member 7 is arranged on the cooling chamber 1 and passes through the material feeding inlet 2 and the material feeding outlet 3, and includes a first guide plate 71 and a second guide plate 72 spaced apart from each other, and a guide groove 73 is formed between the first guide plate 71 and the second guide plate 72, and the guide groove 73 includes a first guide groove 74 and a second guide groove 75 that are interconnected. The first guide groove 74 has a horizontal straight line shape, and the second guide groove 75 has a horizontally arranged wavy shape; the push rod 54 can move with the fixed rod 51 The first movable rod 52 is movable in the guide groove 73 and is movable when the push rod 54 is displaced to the second guide groove 75. When the push rod 54 is displaced to the second guide groove 75, the push rod 54 can be driven to drive the first movable rod 52 to move up and down relative to the fixed rod 51 as the fixed rod 51 is displaced; the blowing device 8 includes a bellows 81 arranged in the cooling chamber 1, and a water-cooling structure 82 arranged in the bellows 81. The bellows 81 is respectively penetrated by an air inlet 83 and an air outlet 84 on the side facing the conveying device. A fan 85 is provided in the bellows 81, and an air outlet pipe 86 that can rotate up and down relative to it is provided at the air outlet 84. The air is driven by the fan 85 to blow the gas from the air inlet 83 enters the inner cavity of the bellows 81 and is sent out by the outlet pipe 86 of the air outlet 84; the first transmission structure is arranged in the bellows 81 and is located on the side of the air outlet 84, which includes a second movable rod 87 movably arranged on the inner side of the cooling chamber 1, and a first connecting rod 88 connected to the side of the air outlet 86, and the second movable rod 87 is respectively provided with a top plate 89 and a first fixed shaft 90, and a movable groove 91 passes through one side of the first connecting rod 88, and the first fixed shaft 90 is movably arranged in the movable groove 91, and the top rod 54 can abut against the lower side of the top plate 89 and drive the top plate 89 to move upward.

[0033] Specifically, the conveying track in the conveying device can provide guiding support for the suspension component to increase the structural strength of the suspension component, and then provide the suspension component with power to move along the conveying track through the first driving component, thereby realizing the conveying movement of the workpiece in the suspension component.

[0034] The conveying device is used to enable the hanging member to drive the workpiece to move horizontally from the feeding inlet of the cooling chamber to the feeding outlet at a uniform speed. When the hanging member moves, the top rod in the hanging member is displaced into the guide groove, and as the top rod continues to move through the wavy second guide groove in the guide groove, the top rod can be forced to move up and down, thereby causing the first movable rod in the hanging member to move up and down relative to the fixed rod, thereby realizing the up and down displacement of the workpiece located on the hanging member. At the same time, the top rod can abut against the top plate located at the upper end of the second movable rod when it moves up and down, so as to drive the top plate and the second movable rod to move upward as the top rod moves upward, and then the first fixed axis in the second movable rod moves upward. The inner side of the movable groove in the first connecting rod is pressed against, thereby driving the outlet pipe to swing up and down synchronously through the first connecting rod. When the fan in the bellows starts working, the cooling air is transported to the air outlet through the air inlet of the bellows. The cooling air passes through the water-cooling structure to achieve heat exchange cooling of the cooling air, effectively enhancing the cooling effect and efficiency of the workpiece. At the same time, the outlet pipe at the air outlet swings up and down synchronously with the up and down movement of the workpiece to form a synergy between dynamic airflow and workpiece movement, which can shorten the cooling time of the workpiece, increase the cooling efficiency, and ensure the cooling rate of different areas of the workpiece. There is no need to install an external drive, and dynamic airflow and workpiece movement can be achieved only through mechanical transmission, effectively reducing energy consumption and cost.

[0035] Moreover, the air inlet and the air outlet of the bellows in the blowing device are both located in the cooling chamber, thereby realizing air circulation cooling and blowing in the cooling chamber.

[0036] Furthermore, the suspension member 5 also includes a rotating ring 58 that is horizontally rotatable and arranged on one side of the fixed rod 51. The first movable rod 52 is movably inserted into the inner side of the rotating ring 58, and a third guide groove 52 is recessed inwardly along the axial direction on one side of the first movable rod 52. A convex portion that can cooperate with the third guide groove 52 is convex on the inner side of the rotating ring 58. A rotating seat 57 is rotatably arranged on the upper end of the first movable rod 52, and the rotating seat 57 is movably arranged on the fixed rod 51 up and down. The top rod 54 is arranged on one side of the rotating seat 57. A transmission gear ring 55 is coaxially arranged on the rotating ring 58. A fixed rack 56 meshing with the transmission gear ring 55 is provided in the cooling chamber 1. The length direction of the fixed rack 56 is parallel to the length direction of the first guide groove 74.

[0037] Specifically, the convex portion in the rotating ring cooperates with the third guide groove of the first movable rod, so that the first movable rod can rotate with the rotating ring relative to the fixed rod, and the first movable rod can move up and down relative to the rotating ring, thereby realizing that the first movable rod can move up and down relative to the fixed rod, and then the rotating seat cooperates with the fixed rod to move up and down, so that when the first movable rod is displaced up and down, the rotating seat can move up and down relative to the fixed rod with the first movable rod, and the upper end of the rotating seat and the first movable rod are rotatably connected through the bearing, so that when the first movable rod rotates with the rotating ring, it will not drive the rotating seat to rotate, so that the top rod located on one side of the rotating seat can remain located in the guide groove of the second driving member;

[0038] When the suspension component is driven to move, the transmission gear ring on the rotating ring engages with the fixed rack in the cooling chamber, and then as the suspension component moves, the transmission gear ring rotates, and then drives the rotating ring and the first movable rod to rotate synchronously, thereby driving the workpiece located in the hook at the lower end of the first movable rod to rotate, and then the second driving component forces the top rod to move up and down, and then drives the first movable rod to move up and down, so that the workpiece can be displaced up and down while rotating circumferentially, thereby forming a synergy between dynamic airflow and workpiece movement, so that the surface coating of the workpiece can be cooled more comprehensively (the cooling rate in different areas remains consistent).

[0039] Furthermore, the first driving member 6 includes a chain conveyor line 61 connected to the suspension member 5, and the conveying track of the chain conveyor line 61 is arranged parallel to the track track of the conveying track 4. Specifically, the links of the transmission chain in the chain conveyor line are fixedly connected to the suspension member, so that the transmission chain is driven by the motor and the sprocket to move while driving the suspension member to move along the conveying track.

[0040] Furthermore, the water cooling device includes a heat conducting plate 92 and a circulation pipe 93 respectively arranged in the air box 81. The heat conducting plate 92 is used to divide the inner cavity of the air box 81 into an air cavity 94 and an installation cavity 95. The circulation pipe 93 is arranged in the installation cavity 95 and abuts against the heat conducting plate 92 for heat exchange. The air cavity 94 is connected between the air inlet 83 and the air outlet 84. The fan 85 is arranged in the air cavity 94. Specifically, cooling ice water flows in the circulation pipe through a circulation pump. As the cooling air in the air cavity passes through the heat conducting plate, the hot air will be blown through the ice heat conducting plate, and then heat exchange is carried out to achieve cold air blowing.

[0041] Furthermore, a condensation water cleaning structure is provided in the wind cavity 94; the condensation water cleaning structure includes a slider 96 movably provided in the wind cavity 94 and a water-absorbing sponge 97 provided on one side of the slider 96 and capable of abutting against the heat conduction plate 92, and a second transmission structure 98 for driving the slider 96 to move up and down along with the second movable rod 87 and to move up and down relative to the wind cavity 94. The heat conduction plate 92 has an inclined section at the lower part of the side facing the wind cavity 94, and the inclined section is used to make the width of the wind cavity 94 wider at the top and narrower at the bottom, so that when the water-absorbing sponge 97 moves to the inclined section along with the slider 96, the water-absorbing sponge 97 can be squeezed to drain water.

[0042] When the cooling air passes through the heat transfer plate, water droplets will form on the outer wall of the heat transfer plate. The hot air raises the surface temperature of the heat transfer plate, causing the water vapor in the surrounding air to liquefy and form water droplets on its surface. This process consumes the water vapor in the surrounding air, so the air becomes relatively dry. In turn, dry cooling air can ensure the cooling quality of the workpiece.

[0043] The condensed water cleaning structure can quickly and effectively clean the condensed water in time to avoid excessive condensed water on the surface of the heat conduction plate. The continuous blowing of the fan will accelerate the evaporation of water, causing the condensed water to be converted back into water vapor and blown onto the workpiece, affecting the quality of the workpiece.

[0044] Specifically, the second transmission structure drives the slider to move up and down, so that the water-absorbing sponge on the slider can clean the condensed water on the heat conduction plate, and when the slider moves downward and drives the water-absorbing sponge to be in the inclined section of the heat conduction plate, the water-absorbing sponge can be squeezed by the space to drain water.

[0045] Furthermore, a collecting box 100 is provided below the wind box 81 and below the heat conducting plate 92, and the inner cavity of the collecting box 100 is connected to the wind cavity 94. The condensed water discharged from the water-absorbing sponge after being squeezed is collected by the collecting box.

[0046] Furthermore, the second transmission structure 98 includes a second connecting rod 17 and a movable frame 11; wherein, the movable frame 11 is movably disposed in the air cavity 94 and can move laterally toward or away from the heat conducting plate 92. A guide chute 12 is provided on one side of the movable frame 11, and a second fixed shaft 13 is provided on one side of the slider 96. The second fixed shaft 13 is movably disposed in the guide chute 12. A connecting plate 14 is provided on one side of the movable frame 11 extending to the outside of the bellows 81. The second connecting rod 17 is hinged between the connecting plate 14 and the second movable rod 87. Specifically, when the second movable rod is driven to move up and down, the connecting rod is used to transmit the movement so that the movable frame can move toward or away from the heat conducting plate. At this time, the guide chute on the movable frame moves accordingly and presses against the slider to move up and down relative to the air cavity, thereby achieving the up and down wiping displacement of the water-absorbing sponge.

[0047] The above overall solution is combined without the need for an external drive. The multi-component linkage transmission of dynamic airflow, dynamic movement of the workpiece, and up and down displacement of the water-absorbing sponge for wiping can be achieved only through mechanical transmission, effectively reducing energy consumption and costs.

[0048] Furthermore, a dust screen 15 is provided at the air inlet 83 to isolate dust.

[0049] Furthermore, the fixing rod 51 is movably arranged on the conveying track 4 via the pulley 16 .
