Description

Technical Field

[0001] This utility model belongs to the field of spray gun technology, and in particular relates to a dual-cylinder spray gun structure for a pipeline spraying robot. Background Technology

[0002] In the field of pipeline spraying operations, the spray gun structure of traditional spraying robots is a single-cylinder spray gun structure. When controlling the movement of the needle, the needle is subjected to force on one side, which will cause uneven movement and uneven coating. Moreover, the force on one side of the needle will affect its service life. In addition, traditional spray guns lack replaceability in connection structure, making it difficult to adjust according to different needs and unable to achieve diverse spraying effects. Utility Model Content

[0003] The purpose of this invention is to provide a dual-cylinder spray gun structure for a pipeline spraying robot to solve the problems caused by the uneven movement of traditional spray guns, which result in uneven paint entry and exit.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: It includes a main body, a fixing member on the side of the main body, a rotary joint on the side of the fixing member, a first fixing screw below the rotary joint, a connector below the first fixing screw, a second fixing screw at the other end of the connector, a universal joint above the second fixing screw, a butterfly seat fixing screw on the side of the universal joint, a butterfly seat on the side of the butterfly seat fixing screw, a nozzle on the side of the butterfly seat, a gun needle on the side of the main body away from the fixing member, a connecting plate on the side of the gun needle, fixing grooves penetrating both the upper and lower ends of the connecting plate, a connecting groove penetrating the middle of the connecting plate, a fixing ring on the side of the connecting groove away from the main body, and cylinders on the side of the fixing groove away from the fixing ring.

[0005] Furthermore, the connecting member used between the first fixing wire and the second fixing wire is an extension rod.

[0006] Furthermore, the connector used between the first fixing wire and the second fixing wire can also be replaced with a universal rotary joint.

[0007] Furthermore, the rod portion of the cylinder is fixed inside the fixing groove, and the two cylinders are respectively fixed above and below the main body.

[0008] Furthermore, the fixing ring is fixedly connected to the connecting plate.

[0009] Furthermore, the gun needle is fixedly connected to the retaining ring.

[0010] Furthermore, the gun needle is fixedly connected to the connecting plate via the retaining ring.

[0011] Furthermore, the extension rod is connected to the rotary joint and the universal joint via the first fixing wire and the second fixing wire.

[0012] Furthermore, the nozzle orifice portion is located inside the butterfly mount.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0014] 1. Two cylinders push the connecting plate away from the main body, which, in conjunction with the fixing groove, moves the needle away from the main body. This allows the spray gun to begin spraying. The dual-cylinder structure controls the movement of the needle, ensuring that both sides of the needle are stressed during movement. This results in smoother needle movement and more even paint application, which is better than the unilateral stress on a single-cylinder needle. It also extends the service life of the needle in the dual-cylinder spray gun.

[0015] 2. The connector in this utility model can be replaced with an extension rod or a universal swivel joint, so that the spray gun can be replaced with different connectors according to different needs, thereby obtaining different spraying effects. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1:

[0023] This example provides a dual-cylinder spray gun structure for a pipeline spraying robot, such as... Figures 1 to 3 As shown, it includes a main body 2, a fixing member 3 on the side of the main body 2, a rotary joint 4 on the side of the fixing member 3, a first fixing wire 11 below the rotary joint 4, a connector below the first fixing wire 11, a second fixing wire 6 at the other end of the connector, a universal joint 7 above the second fixing wire 6, a butterfly seat fixing wire 8 on the side of the universal joint 7, a butterfly seat 9 on the side of the butterfly seat fixing wire 8, a nozzle 10 on the side of the butterfly seat 9, a gun needle 1 on the side of the main body 2 away from the fixing member 3, a connecting plate 12 on the side of the gun needle 1, fixing grooves 13 penetrating both the upper and lower ends of the connecting plate 12, a connecting groove 14 penetrating the middle of the connecting plate 12, a fixing ring 15 on the side of the connecting groove 14 away from the main body 2, and cylinders 16 on the side of the fixing groove 13 away from the fixing ring 15. The cylinders and nozzles in this utility model are existing technologies and are not described in detail.

[0024] The first fixing wire 11 and the second fixing wire 6 are connected by an extension rod 5, which lengthens the position of the nozzle, allowing it to be closer to the pipe and improving the spraying effect. The rod part of the cylinder 16 is fixed inside the fixing groove 13, and the two cylinders 16 are fixed above and below the main body 2 respectively. The fixing ring 15 is fixedly connected to the connecting plate 12. The gun needle 1 is fixedly connected to the fixing ring 15. The gun needle 1 is fixedly connected to the connecting plate 12 through the fixing ring 15. The extension rod 5 is connected to the rotary joint 4 and the universal joint 7 through the first fixing wire 11 and the second fixing wire 6. The rotary joint 4 is used to fix inside the gear. The rotation of the gear drives the parts below the rotary joint 4 and the nozzle 10 to rotate, realizing the rotational spraying of the spray gun. The spray hole part of the nozzle 10 is located inside the butterfly seat 9.

[0025] Example 2:

[0026] The only difference between this embodiment and Embodiment 1 is that, Figure 4 As shown, the extension rod 5 is replaced with a universal rotary joint 17. The universal rotary joint can adjust the angle and direction of the parts below the rotary joint 4 and the nozzle 10, so that it can adapt to different spraying requirements. The universal rotary joint in this utility model is existing technology and will not be described in detail.

[0027] Working principle: When using this utility model, the spray gun is first fixed to the front end of the pipe spraying robot, so that the cylinder 16 and the main body 2 are fixed. Then, the two cylinders 16 are pushed by the robot's control switch. With the cooperation of the fixing groove 13, the connecting plate 12 is pushed away from the main body 2. Through the cooperation of the fixing ring 15 and the connecting groove 14, the gun needle 1 moves away from the main body 2. Then the spray gun will start, so that the paint is sprayed onto the inner wall surface of the pipe through the nozzle 10 during the rotation.

[0028] This invention is not limited to the details of the exemplary embodiments described above, and can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
