Description

Technical Field

[0001] The utility model belongs to the technical field of target spraying, and particularly relates to a device for removing accumulated tumors of a target spraying machine. Background Technique

[0002] A spraying machine is a special painting equipment using spraying technology. The principle is to control the air flow to instantaneously push the air distribution reversing device to reverse, so that the piston of the pneumatic motor makes a stable and continuous reciprocating motion. There is a device for removing accumulated tumors of a target spraying machine disclosed in the prior art. For example, CN212943674U discloses a device for removing accumulated tumors of a target spraying machine, which includes a gun carriage. A control device is arranged at the top position of the gun carriage. A spray head is arranged at the side end of the gun carriage. A powder feeding pipe is arranged above the spray head. A blowing copper pipe is arranged between the spray head and the powder feeding pipe. An installation plate is fixedly connected to the side wall of the gun carriage. A rotary cylinder is arranged on the surface of the installation plate. A rotary turntable is fixedly connected to the outer surface of the rotary cylinder. An extension rod is arranged on the outer surface of the rotary turntable. An adjusting bolt is threadedly connected to the surface of the extension rod.

[0003] The device for removing accumulated tumors of the target spraying machine disclosed in this patent uses a rotary cylinder. During use, the rotary cylinder drives the tumor hitting head to rotate to knock off the spark accumulated tumors remaining on the spray head, and blows compressed air through the blowing copper pipe to the powder spraying port of the powder feeding pipe to automatically clean the accumulated tumors at the powder spraying port of the powder feeding pipe. The structure is simple and easy to use. It is undeniable that the device for removing accumulated tumors of the target spraying machine disclosed in this patent can indeed achieve the above effects, but it still has certain deficiencies: driving the tumor hitting head to rotate through the rotary cylinder is not convenient to control the rotation amplitude of the tumor hitting head. If the rotation amplitude is large, the tumor hitting head may not contact the spray head for a period of time, wasting time and having low efficiency. If the rotation amplitude is small, it may lead to incomplete removal of the accumulated tumors.

[0004] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

[0022] The following is a clear and complete description of the technical solution of the patent of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present utility model.

[0023] Embodiment

[0024] Refer to the appendix Figures 1-4 A burring removal device for a target spraying machine, comprising a gun carriage 1, an electric push rod 2 arranged on the top of the gun carriage 1, a burring head 3 slidably mounted on the electric push rod 2, and a control mechanism arranged on the top of the gun carriage 1 for controlling the rotation angle of the burring head 3; Specifically, the control mechanism includes a control box 4 fixedly mounted on the gun carriage 1, a worm 5 rotatably mounted inside the control box 4, a motor 6 fixedly mounted on one side of the control box 4, a worm gear 7 rotatably mounted inside the control box 4 and meshing with the worm 5, a crank 8 rotatably mounted on the worm gear 7, a rotating plate 9 rotatably mounted on the crank 8, and a connecting rod 10 fixedly mounted on the rotating plate 9.

[0025] When the user uses the device to remove the burring of sparks, first start the electric push rod 2, the moving end of the electric push rod 2 starts to move, drive the burring head 3 to move along with the movement of the electric push rod 2 until it moves to a suitable position. At this time, start the motor 6, the output end of the motor 6 starts to rotate, drive the worm 5 inside the control box 4 to rotate through the rotation of the output end of the motor 6, drive the worm gear 7 meshing with it to rotate through the rotation of the worm 5. While the worm gear 7 is rotating, the crank 8 rotatably mounted at the eccentric position of the worm gear 7 starts to rotate. Through the rotational movement of the crank 8, drive the rotating plate 9 to perform a reciprocating rotational movement within a certain range. This reciprocating rotation of the rotating plate 9 then drives the connecting rod 10 to perform a reciprocating swing within a corresponding angle. The reciprocating swing of the connecting rod 10 then drives the electric push rod 2 to perform a rotational movement, causing the electric push rod 2 to perform a reciprocating rotation within a limited angle. Since the burring head 3 is mounted on the electric push rod 2 in a sliding connection manner, therefore, with the reciprocating rotation of the electric push rod 2, the burring head 3 also synchronously performs a reciprocating rotational movement within a certain angle.

[0026] In this embodiment, in order to be able to change the position of the burr head 3, a limit block 11 is fixedly connected to the side surface of the electric push rod 2. A chute 12 is opened inside the limit block 11, and the burr head 3 is slidably connected inside the chute 12. When the user uses this device to remove the spark burr, when it is necessary to adjust the position of the burr head 3, the operator can manually push the burr head 3 to slide along the chute 12 pre-opened on the limit block 11. This operation enables the burr head 3 to move freely within the range defined by the chute 12, thereby flexibly changing its position to meet different requirements.

[0027] In this embodiment, in order to spray the target material, a spraying plate 13 is fixedly connected to the top of the gun carriage 1. A spray head 14 is fixedly connected to one side of the spraying plate 13, and a powder feeding pipe 15 is fixedly connected to one side of the spraying plate 13. The powder is ejected downward through the powder spraying port of the powder feeding pipe 15. At this time, the powder is sprayed onto the surface of the target material through the spray head 14 fixedly connected to the spraying plate 13.

[0028] In this embodiment, in order to clean the burr on the powder feeding pipe 15, the powder feeding pipe 15 is fixedly connected above the spray head 14, and a blower 16 is fixedly connected to the top of the gun carriage 1. A blowing copper pipe 17 is fixedly connected to the blower 16, and the blowing copper pipe 17 is arranged directly below the powder spraying port on the powder feeding pipe 15. The output end of the motor 6 penetrates the control box 4, and the output end of the motor 6 is fixedly connected to the worm 5. The connecting rod 10 penetrates the control box 4, and the end of the connecting rod 10 away from the rotating plate 9 is fixedly connected to the bottom of the electric push rod 2.

[0029] When the user uses this device to remove the spark burr, when the blower 16 is started, the strong air flow generated by it is accurately guided and ejected through the blowing copper pipe 17. The blowing copper pipe 17 is arranged directly below the powder spraying port of the powder feeding pipe 15, ensuring that the compressed air can directly act on the powder spraying port area. As the compressed air is ejected, it not only directly blows the powder spraying port of the powder feeding pipe 15, effectively removing the burr that may accumulate here, but also this air flow flows on the inner and outer walls of the powder feeding pipe 15, forming an all-round cleaning effect. It not only cleans the direct area of the powder spraying port, but also takes into account the cleaning of the inner and outer walls of the powder feeding pipe 15, preventing possible blockage or fouling problems during long-term use. Therefore, through the coordinated action of the blower 16 and the blowing copper pipe 17, a comprehensive cleaning of the powder spraying port of the powder feeding pipe 15 and its surrounding area is achieved, ensuring the smooth operation of the spraying machine and the stability of the spraying quality.

[0030] The foregoing description of the specific exemplary embodiments of the present utility model is for purposes of illustration and exemplification. These descriptions are not intended to limit the present utility model to the precise forms disclosed, and it is apparent that many changes and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present utility model and its practical applications, so that those skilled in the art can implement and utilize the various different exemplary embodiments of the present utility model, as well as various different selections and changes.
