Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate spray paint processing, in particular to a spray paint recovery device. Background Art

[0002] Spraying is a coating method in which the paint is dispersed into uniform and fine droplets by pressure or centrifugal force through a spray gun or a disc atomizer and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc.

[0003] For example, a paint recovery device is disclosed in the Chinese utility model patent publication number (CN205462919U), which includes a paint collection chamber, a recovery pipe and a paint recoverer. The opening of the paint collection chamber faces the direction of paint spraying and is arranged in the spraying range of the paint. An air intake port is opened in the paint collection chamber, and the air intake port is connected to the paint recoverer through the recovery pipe. The air intake port inhales air to form a recovery airflow in the paint collection chamber. The direction of the recovery airflow is perpendicular to the direction of paint spraying. This utility solves the problem that the space of the spraying room is relatively small and there are many internal equipments. The airflow generated by the air intake port is easy to generate turbulence in the spraying room, resulting in different coating thickness on the material to be sprayed. However, this patent can only recover part of the paint mist at the nozzle. When spraying on the workpiece, in order to ensure that the workpiece is sprayed evenly, the corners of the workpiece need to exceed a part for spraying. The excess part of the paint cannot be recovered, resulting in low recovery efficiency of the entire device, affecting practicality. Utility Model Content

A spray gun 5 is provided above the base plate 1, and a second recovery mechanism 6 for recovering the surrounding paint mist during the spraying process is provided on the spray gun 5, so that the paint mist scattered around the paint during spraying can be collected to avoid it from floating in the paint spraying room.

[0034] See also Figure 2-5 In order to collect the paint that exceeds the spraying range in order to ensure the integrity of the spraying during the spraying process, the first recovery mechanism 4 in this embodiment includes a fixing part 41, a shielding part 42, and a spraying part 43. The fixing part 41 is arranged on the support platform 2, and is used to clamp and fix the workpiece to be sprayed so that the workpiece maintains stability during the painting process.

The spraying part 43 is arranged on the bottom plate 1, and is used to recover the blocked paint, so as to facilitate the recycling of the paint collected on the baffle 423.

[0035] In this embodiment, the fixing member 41 includes a motor 411, a rotating plate 412, two connecting plates 413, two connecting blocks 414, and two clamping plates 415. The motor 411 is fixed to the lower surface of the support platform 2, and the output shaft of the motor 411 passes through and extends to the interior of the support platform 2 and is fixed to the rotating plate 412. The output shaft of the motor 411 drives the rotating plate 412 to rotate. The two connecting plates 413 are hinged to the upper surface of the rotating plate 412 through a hinge shaft, and are symmetrically distributed with the center axis of the rotating plate 412. The rotating plate 412 drives the connecting plate 413 to rotate, and the two connecting blocks 414 are respectively hinged to the two connecting plates 413 through a hinge shaft. The connecting plate 413 drives the connecting block 414 to rotate. The upper surfaces of the two connecting blocks 414 are penetrated The upper side of the child support platform 2 is extended and fixed with two clamping plates 415 respectively. A limiting opening 416 is provided on the upper surface of the support platform 2. Both the two connecting blocks 414 are located inside the limiting opening 416. The width of the limiting opening 416 matches the width of the connecting block 414. Since the connecting block 414 is in the limiting opening 416, the limiting opening 416 limits the angle and movement trajectory of the connecting block 414. Therefore, with the cooperation of the hinge shaft, the connecting plate 413 rotates to drive the connecting block 414 to move, and the connecting block 414 drives the clamping plate 415 to move, so that the clamping plate 415 clamps and fixes the workpiece.

When spraying the edge of the workpiece, in order to ensure that the edge can be fully coated, it is necessary to exceed a certain distance for spraying, so that part of the paint will be sprayed on the baffle 423. The collection box 424 is placed on the bottom plate 1, and the collection box 424 is located directly below the baffle 423. The spraying part 43 includes a water tank 431, a water pump 432, a water inlet pipe 433, a water outlet pipe 434, a connecting pipe 435, and a plurality of nozzles 436.

The water pump 432 pumps out and pressurizes the water in the water tank 431 through the water inlet pipe 433. One end of the water outlet pipe 434 is connected to the water outlet end of the water pump 432, and the other end of the water outlet pipe 434 is connected to the connecting pipe 435. The pressurized water is passed into the connecting pipe 435 through the water outlet pipe 434. The connecting pipe 435 is fixed to the right side of the baffle 423, and multiple nozzles 436 are connected to the outside of the connecting pipe 435. The connecting pipe 435 passes water into the nozzle 436, and the nozzle 436 sprays water on the baffle 423, so that the paint flows into the collection box 424 driven by the water flow and is collected.

[0036] It should be noted that the distance between the front and rear inner walls of the collection box 424 is greater than the length of the baffle 423, and the width of the collection box 424 is greater than the width of the baffle 423, so that the collection box 424 can completely surround the baffle 423 to avoid water flow during collection and spilling paint outside to cause waste.

[0037] See also Figure 6 In order to collect the paint mist scattered around the paint during painting to prevent it from drifting in the paint spraying room, the second recovery mechanism 6 in this embodiment includes a handle 61, a spraying part 62, and a recovery part 63. The handle 61 is fixed to the outer side of the spray gun 5, and the spraying part 62 is arranged on the spray gun 5 to allow the paint to be sprayed from the spray gun 5, so that the operator can control the spraying position. The recovery part 63 is arranged on the spray gun 5 to recover the paint mist around the sprayed paint, thereby improving the efficiency of paint recovery.

[0038] In this embodiment, the spraying component 62 includes a feed pipe 621 and a nozzle 622. One end of the feed pipe 621 is connected to the right side of the spray gun 5, and the nozzle 622 is connected to the left side of the spray gun 5. The feed pipe 621 passes the paint into the interior of the spray gun 5, and the nozzle 622 sprays the paint on the surface of the workpiece. The recovery component 63 includes a recovery cylinder 631, multiple vacuum suction pipes 632, multiple vacuum pumps 633, multiple air pipes 634, and multiple recovery pipes 635. The recovery cylinder 631 is fixed to the outside of the spray gun 5, and the multiple vacuum suction pipes 632 are all fixed to the outside of the recovery cylinder 631 and are symmetrically distributed around the central axis of the recovery cylinder 631.

The other end of each vacuum suction pipe 632 is connected to a plurality of recovery pipes 635, and a plurality of vacuum pumps 633 are fixed to the outside of the spray gun 5. One end of a plurality of air pipes 634 is connected to the output end of a plurality of vacuum pumps 633, and the other end of a plurality of air pipes 634 is connected to a plurality of vacuum suction pipes 632. The vacuum pump 633 evacuates the interior of the vacuum suction pipe 632 through the air pipe 634 to generate a negative pressure inside the vacuum suction pipe 632, thereby sucking out the paint mist around the paint, and the recovery pipe 635 collects the sucked-out paint. Since the vacuum suction pipes 632 are symmetrically distributed around the central axis of the recovery cylinder 631, the direction in which the paint is sprayed will not be affected when the paint is recovered.

[0039] The working principle of the above embodiment is:

[0040] (1) First, place the workpiece on the support table 2, turn on the motor 411, and the output shaft of the motor 411 drives the rotating plate 412 to rotate, the rotating plate 412 drives the connecting plate 413 to rotate, and the connecting plate 413 drives the connecting block 414 to rotate. Since the connecting block 414 is in the limiting opening 416, the limiting opening 416 limits the angle and movement trajectory of the connecting block 414. Therefore, with the cooperation of the hinge shaft, the connecting plate 413 rotates to drive the connecting block 414 to move, and the connecting block 414 drives the clamping plate 415 to move, so that the clamping plate 415 clamps and fixes the workpiece. After the workpiece is fixed, open the spray gun 5, and the feed pipe 621 passes the paint into the inside of the spray gun 5, and the nozzle 622 sprays the paint on the surface of the workpiece.

[0041] (2) When the nozzle 622 sprays the paint, it will scatter, resulting in paint mist around it. Therefore, during the spraying process, the vacuum pump 633 is turned on. The vacuum pump 633 evacuates the inside of the vacuum suction pipe 632 through the air pipe 634, so that a negative pressure is generated inside the vacuum suction pipe 632, thereby sucking out the paint mist around the paint, and the sucked-out paint is collected by the recovery pipe 635. When spraying the edge of the workpiece, in order to ensure that the edge can be fully coated, it is necessary to exceed a certain distance for spraying, so that part of the paint will be sprayed on the baffle 423. At this time, the water pump 432 is turned on. The water pump 432 draws out the water inside the water tank 431 through the water inlet pipe 433 and pressurizes it, and then passes the pressurized water into the connecting pipe 435 through the water outlet pipe 434. The connecting pipe 435 passes the water into the nozzle 436, and the nozzle 436 sprays the water on the baffle 423, so that the paint flows into the collection box 424 driven by the water flow and is collected.
