Description

Technical Field

[0001] This utility model relates to the field of spray painting technology, specifically to a flame dust removal device for spray painting. Background Technology

[0002] Spray painting is a coating method that uses a spray gun or disc atomizer to disperse the paint into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object to be coated. After spray painting, the surface of the workpiece needs to be baked with a flame to remove dust.

[0003] Traditional processes for improving workpiece surface activity and cleanliness involve using a manual spray gun to evenly coat the workpiece surface with paint. Wiping the workpiece surface can enhance the surface activity of the paint and remove dust.

[0004] However, in actual use, the above-mentioned equipment often results in poor paint adhesion and a high scrap rate due to the long working hours of the staff, which may lead to inadequate flame treatment and dust removal. This also greatly increases labor costs. In view of this, we propose a flame dust removal device for painting processes. Utility Model Content

[0005] The purpose of this invention is to provide a flame dust removal device for spray painting to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flame dust removal device for spray painting, comprising a robotic arm, a flame-spraying device fixedly connected to the end of the robotic arm, a connecting device fixedly connected to the bottom of the flame-spraying device, a nozzle fixedly connected to the end of the flame-spraying device, and an adjustment assembly provided on the outer surface of the nozzle, the adjustment assembly comprising:

[0007] An air intake slot is formed on the outer surface of the nozzle. A rotating component is rotatably connected to the inner wall side of the air intake slot. A movable component is threadedly connected to the outer surface of the rotating component. A stop is fixedly connected to the end of the movable component.

[0008] Preferably, the rotating component is composed of a threaded rod fixedly connected to the side of the rotating block, and the size of the rotating component is adapted to the size of the air intake groove, which allows the rotating component to rotate well inside the air intake groove.

[0009] Preferably, the movable part is T-shaped, and the horizontal part of the movable part is located inside the air intake groove near its end, which allows the movable part to move inside the air intake groove.

[0010] Preferably, the stop is shaped like a frustum, the large-diameter end of the stop is arc-shaped, and the large-diameter end is fixedly connected to the vertical end of the movable part. The center of the stop corresponds to the center of the nozzle, which allows the stop to move inside the nozzle.

[0011] Preferably, the flame-spraying device is provided with a protective component at its end. The protective component includes a mounting component, which is fixedly connected to the end of the flame-spraying device. A protective sleeve is threaded onto the outer surface of the mounting component, and a spring is fixedly connected to the inner wall of the protective sleeve. A pressing component is fixedly connected to the end of the spring.

[0012] Preferably, the center of the mounting component corresponds to the center of the nozzle, and the size of the mounting component is adapted to the size of the protective sleeve.

[0013] Preferably, the pressing element is disposed inside the protective sleeve, and the size of the pressing element is adapted to the size of the protective sleeve.

[0014] Compared with the prior art, this utility model provides a flame dust removal device for spray painting, which has the following beneficial effects:

[0015] 1. This flame dust removal device for spray painting is designed to spray flames more evenly onto the outer surface of the workpiece. During the processing of the painted workpiece, a robotic arm controls the nozzle at the end of the flame-spraying device to aim the flame at the outer surface of the workpiece. The robotic arm can effectively control the distance between the nozzle and the workpiece, thus improving the surface activity of the paint and achieving a better dust removal effect. Simultaneously, the operator can rotate the rotating component, causing the threaded movable part on the outer surface of the rotating component to move within the air inlet groove. This allows adjustment of the space between the baffle and the inner wall of the nozzle, ensuring that the flame emitted from the nozzle contacts the outer surface of the workpiece evenly.

[0016] 2. This flame dust removal device for spray painting is designed to provide better protection when the equipment is not in use. When the equipment is not in use, the protective cover can be threaded onto the outer surface of the mounting component, allowing the side of the pressing component to contact the nozzle. At the same time, the protective cover can effectively shield the nozzle, thereby preventing dust in the air from entering the nozzle when the equipment is not in use. Attached Figure Description

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a flame dust removal device for spray painting, including a robotic arm 1, a flame-spraying device 2 fixedly connected to the end of the robotic arm 1, a connecting device 3 fixedly connected to the bottom of the flame-spraying device 2, and a connection port provided at the end of the connecting device 3 that can be connected to a gas supply pipe, so that the gas can be well input into the flame-spraying device 2. A nozzle 4 is fixedly connected to the end of the flame-spraying device 2, and an adjustment component 5 is provided on the outer surface of the nozzle 4. The adjustment component 5 includes an air inlet groove 501, a rotating part 504, a movable part 502, and a stop part 503.

[0023] In this embodiment of the present invention, an air inlet groove 501 is formed on the outer surface of the nozzle 4. A rotating member 504 is rotatably connected to the inner wall side of the air inlet groove 501. The rotating member 504 is composed of a rotating block with a threaded rod fixedly connected to its side. The size of the rotating member 504 is adapted to the size of the air inlet groove 501, which allows the rotating member 504 to rotate well inside the air inlet groove 501. A movable member 502 is threadedly connected to the outer surface of the rotating member 504. The movable member 502 is T-shaped. The horizontal part of the movable member 502 is located near its end inside the air inlet groove 501, which allows the movable member 502 to move inside the air inlet groove 501. A stop member 503 is fixedly connected to the end of the movable member 502. The stop member 503 is frustum-shaped. The large diameter end of the stop member 503 is arc-shaped and fixedly connected to the end of the vertical part of the movable member 502. The center of the stop member 503 corresponds to the center of the nozzle 4, which allows the stop member 503 to move inside the nozzle 4.

[0024] Meanwhile, a protective component 6 is provided at the end of the flame-spraying device 2. The protective component 6 includes a mounting part 601, which is fixedly connected to the end of the flame-spraying device 2. The center of the mounting part 601 corresponds to the center of the nozzle 4. The size of the mounting part 601 is adapted to the size of the protective sleeve 602. The outer surface of the mounting part 601 is threadedly connected to the protective sleeve 602. A spring 603 is fixedly connected to the inner wall of the protective sleeve 602. A pressing part 604 is fixedly connected to the end of the spring 603. The pressing part 604 is located inside the protective sleeve 602. The size of the pressing part 604 is adapted to the size of the protective sleeve 602. In this way, when the equipment is not in use, the protective sleeve 602 can be threadedly connected to the outer surface of the mounting part 601, so that the side of the pressing part 604 can contact the nozzle 4. At the same time, the protective sleeve 602 can effectively cover the nozzle 4, thereby effectively preventing dust in the air from entering the nozzle 4 when the equipment is not in use.

[0025] In this invention, when the equipment processes the painted workpiece, the robotic arm 1 controls the nozzle 4 at the end of the flame-spraying device 2 to spray flames onto the outer surface of the workpiece. The robotic arm 1 can effectively control the distance between the nozzle 4 at the end of the flame-spraying device 2 and the workpiece, thereby improving the surface activity of the paint on the outer surface of the workpiece and achieving a good dust removal effect. At the same time, the operator can rotate the rotating part 504, causing the movable part 502, which is threadedly connected to the outer surface of the rotating part 504, to move inside the air inlet groove 501. This allows the space between the baffle 503 and the inner wall of the nozzle 4 to be adjusted, so that the flames sprayed from the nozzle 4 can evenly contact the outer surface of the workpiece.

[0026] Furthermore, when the equipment is not in use, the protective sleeve 602 can be threaded to the outer surface of the mounting part 601, so that the side of the pressing part 604 can contact the nozzle 4. At the same time, the protective sleeve 602 can effectively cover the nozzle 4, thereby effectively preventing dust in the air from entering the nozzle 4 when the equipment is not in use.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
