Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile powder spraying, in particular to an aluminum profile powder spraying device. Background Art

[0002] Powder spraying is the process of spraying powder coating onto the surface of a workpiece using powder spraying equipment (electrostatic spraying machine). Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; the powdery coating is leveled and solidified through high-temperature baking to become a final coating with different effects (different types of powder coating effects); the spraying effect of powder spraying is superior to that of painting in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, and the cost is also lower than that of painting with the same effect.

[0003] The aluminum profiles on the market now have some defects during spraying, and the subsequent repairs through the electrostatic spray machine are very troublesome, which will result in the spraying device being too large and inconvenient to repair.

[0004] For example, a spraying device for spraying powder on an aluminum profile disclosed in Chinese patent CN212263628U adopts a slot structure on a handle that is threadedly connected to a rotary sleeve at the lower end of a balloon. The spraying powder and the ball can then be pushed downward by holding the balloon, and then the ball can be detached downward from the through hole. The spraying powder can then enter the spray gun tube, and then can be sprayed to the desired repair area through the nozzle on the spray gun tube. The hand can then be released from the balloon, and then the ball can be moved upward, so that the ball can close the upper end of the spray gun tube.

[0005] However, the spraying device needs to be manually held for spraying, and manual spraying cannot control the moving speed well, resulting in uneven spraying, etc. In addition, the spraying environment is very harmful to the human body, and there are great health risks in long-term spraying work.

[0006] For this reason, we urgently need to provide a hand-free aluminum profile powder spraying device. Utility Model Content

[0007] The purpose of the utility model is to provide an aluminum profile powder spraying device to solve the problem that the spraying device proposed in the above background technology needs to be manually held for spraying, and the manual spraying cannot control the moving speed well, resulting in uneven spraying, etc., and the spraying environment is very harmful to the human body. There are great health risks in long-term spraying work.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum profile powder spraying device, comprising a spray box and a support column, the support column is fixedly connected to the four corners of the lower side of the spray box, the front end of the spray box is hinged with a box door by a hinge, a handle is fixedly connected to the middle position of the front right end of the box door, the inner and outer ends of the spray box are connected to a spray mechanism, the spray mechanism comprises a spray unit and a drying unit, the spray unit is arranged at the inner and outer ends of the spray box, and the drying unit is arranged at the left end of the spray box.

[0009] The spraying unit comprises a cylinder, a first bearing, a lower clamping plate, a first motor, an upper clamping plate, a limit rod, a second motor, a reciprocating screw rod, a second bearing, a moving block, a storage box, a rubber tube and a spray head. The cylinder is fixedly connected to the middle position of the lower left end of the spray box, the first bearing is fixedly connected to the outer side of the upper end of the output shaft of the cylinder, the lower clamping plate is fixedly connected to the upper end of the first bearing, the first motor is fixedly connected to the middle position of the upper left end of the spray box, the upper clamping plate is fixedly connected to the lower end of the output shaft of the first motor, the limit rod is vertically fixedly connected to the rear end on the right side of the inner side of the spray box, the second motor is fixedly connected to the front end on the right side of the upper side of the spray box, the reciprocating screw rod is fixedly connected to the lower end of the output shaft of the second motor, the second bearing is fixedly connected to the right front end of the bottom end inside the spray box, the moving block is connected to the outer end of the reciprocating screw rod, the storage box is fixedly connected to the middle position of the right side of the spray box, the rubber tube is fixedly connected to the inner left end of the storage box, and the spray head is fixedly connected to the inner middle position of the moving block.

[0010] A further improvement is that the upper side of the lower clamping plate abuts against the lower end of the aluminum profile to be sprayed, and the lower side of the upper clamping plate abuts against the upper end of the aluminum profile to be sprayed. Therefore, after the aluminum profile to be sprayed is placed on the lower clamping plate, the cylinder is started to extend the output shaft to drive the lower clamping plate to move up, until the upper end of the aluminum profile is driven to move up to the point where its upper end contacts the lower side of the upper clamping plate, and then the aluminum profile to be sprayed can be fixed between the lower clamping plate and the upper clamping plate.

[0011] A further improvement is that a limit hole is provided at the middle position of the rear end of the moving block, a threaded hole is provided at the middle position of the front end of the moving block, the outer side of the limit rod is slidably connected to the inner side of the limit hole, the outer side of the reciprocating screw is threadedly connected to the inner side of the threaded hole, and the outer side of the lower end of the reciprocating screw is fixedly connected to the inner side of the second bearing. Thus, when the second motor is started and its output shaft rotates to drive the reciprocating screw to rotate, the moving block on the outer side of the reciprocating screw can be driven to move up and down repeatedly along the outer side of the limit rod.

[0012] A further improvement is that one end of the rubber tube away from the material storage box is fixedly connected to the right end of the nozzle, so that when the nozzle is opened, the powder in the material storage box can enter the nozzle through the rubber tube and then be sprayed to the left end to the outside of the aluminum profile clamped between the lower clamping plate and the upper clamping plate at the left end.

[0014] A further improvement is that the hot air flow direction of the hot air blower is from left to right. Thus, when the hot air blower is started, the hot air flow can be blown to the right between the aluminum profiles between the lower clamping plate and the upper clamping plate, so that the powder coating sprayed on the outside is leveled and solidified through high-temperature baking, so that the powder is firmly fixed to the outer end of the aluminum profile.

[0015] A further improvement is that an observation window is fixedly connected to the interior of the box door, and the observation window is made of transparent glass, so that the spraying condition of the aluminum profile in the spray box can be observed at any time through the transparent observation window.

[0016] In summary, the present application discloses an aluminum profile powder spraying device.

[0017] By opening the nozzle, the technical solution allows the powder in the storage box to enter the nozzle through the rubber tube and then be sprayed to the left end to the outside of the aluminum profile clamped between the lower clamping plate and the upper clamping plate at the left end, without the need for workers to hold a spraying device for spraying.

[0018] Furthermore, by starting the hot air blower, the hot air flow can be blown to the right between the aluminum profiles between the lower clamping plate and the upper clamping plate, so that the powder coating sprayed on the outside is leveled and cured through high-temperature baking, so that the powder is firmly fixed to the outer end of the aluminum profile.
