Description

Technical Field

[0001] This application relates to the technical field of container production equipment, and in particular to a container painting device. Background Technology

[0002] After the container body is welded, the inner walls of the container usually need to be painted with anti-corrosion paint. Since manual painting inside the container is more likely to cause injury to workers in a relatively enclosed space, automated painting equipment is usually used inside the container for painting.

[0003] The existing Chinese invention patent application with application number CN200810163823.0 discloses an automatic powder coating device, coating system and coating method for the inside of a container. It includes a cantilever arm, one end of which is fixed to a frame, and a spray gun is arranged on the frame. During the painting process, the cantilever arm and the container move at a relatively uniform speed, and the cantilever arm gradually extends into the container to spray paint the inner wall of the container.

[0004] To improve bending strength, some shipping containers typically feature a channel-shaped bulkhead structure on their inner walls. This design prevents the container surface from easily deforming under pressure or impact. When a cantilever arm extends into the container to paint the walls, the fixed spray angle of the spray gun results in poor painting of the channel-shaped inner walls, potentially requiring more manual touch-up painting later. Summary of the Invention

[0005] To improve the painting effect on the inner wall of a container, this application provides a container painting device.

[0006] The technical solution adopted in this application is as follows:

[0007] A container painting apparatus includes a frame, a painting assembly, and a sliding plate for placing a container. The frame includes a body and a cantilever arm mounted on the body. The painting assembly is mounted on the end of the cantilever arm away from the body. The sliding plate is slidable along a direction parallel to the length of the cantilever arm. The painting assembly includes a bracket slidably mounted on the cantilever arm, a mounting rod mounted on the bracket facing the surface to be painted, and a spray gun mounted on the mounting rod. A power assembly for driving the bracket to reciprocate along the length of the cantilever arm is installed between the frame and the bracket. The mounting rod is rotatably mounted on the bracket, and a linkage structure is provided between the cantilever arm and the mounting rod. When the bracket reciprocates on the cantilever arm, the linkage structure can drive the mounting rod to reciprocate, thereby causing the spray gun to reciprocate. During painting, the sliding speed of the sliding plate is less than the reciprocating speed of the bracket.

[0008] By adopting the above technical solution, during painting, the container is placed on a sliding plate, which then slides towards the cantilever arm. The cantilever arm gradually enters the container's interior cavity, allowing the painting assembly to paint the container's inner wall. During the painting process, a power assembly drives the support to reciprocate, and the sliding speed of the sliding plate is less than the reciprocating speed of the support. As the support slides, the mounting rod rotates reciprocally, causing the spray gun to reciprocate. This allows the spray gun to be aimed at the container's trough-shaped inner wall and its angle to be adjusted, painting the trough-shaped inner wall at different angles, thus improving the painting effect on the container's inner wall.

[0009] Optionally, the outer walls at both ends of the mounting rod are rotatably connected to rotating seats, which are mounted on the bracket; the linkage structure includes an abutment strip mounted on the cantilever arm and an abutment wheel coaxially mounted on the outer wall of the mounting rod. When the bracket slides, the abutment wheel can abut against the surface of the abutment strip to drive the abutment wheel to rotate.

[0010] By adopting the above technical solution, when the power component drives the bracket to slide on the cantilever beam, the abutment wheel can rotate on the abutment bar, thereby driving the rotation of the mounting rod, and thus realizing the reciprocating adjustment of the spray gun orientation.

[0011] Optionally, the surface of the abutment strip is provided with a first friction section and a second friction section, the second friction section is located on both sides of the first friction section, and the frictional resistance between the abutment wheel and the first friction section is greater than the frictional resistance between the abutment wheel and the second friction section.

[0012] By adopting the above technical solution, the friction between the friction wheel and the first friction section is greater, making it easier for the friction wheel to rotate synchronously on the first friction section. When the friction wheel moves to the second friction section, it can be decelerated. When the bracket moves to the maximum displacement in one direction and stops, the mounting rod gradually decelerates during this process, thereby reducing the force exerted by the bracket on the cantilever arm. In addition, when the friction wheel moves to the second friction section, the spray gun is in an inclined state, which can also better spray paint the inner wall of the box trough.

[0013] Optionally, a sleeve is slidably fitted on the outer wall of the mounting rod, the spray gun is mounted on the sleeve, the sleeve can slide along the length direction of the mounting rod, and a trigger is provided between the sleeve and the rotating seat. When the mounting rod rotates and drives the sleeve to rotate, the trigger can drive the sleeve to slide back and forth along the length direction of the mounting rod.

[0014] By adopting the above technical solution, during the rotation of the mounting rod, the trigger can drive the sleeve to slide along the axis of the mounting rod, thereby allowing the position of the spray gun to slide back and forth along the axis of the mounting rod, thus further improving the painting effect on the inner wall of the box.

[0015] Optionally, an elastic element is provided between the sleeve and the mounting rod. The trigger element includes a trigger block mounted on the rotating seat. A protrusion is provided at one end of the sleeve near the trigger block. When the sleeve rotates, the protrusion can be pressed against the trigger block and drive the sleeve to slide away from the trigger block. At this time, the elastic element is in a compressed state to provide a force for the sleeve to move towards the trigger block.

[0016] By adopting the above technical solution, during the rotation of the mounting rod, the protrusion can abut against the trigger block, thereby pushing the sleeve to slide and compressing the elastic element. When the protrusion and the trigger block disengage, the elastic element can drive the sleeve to reset. Therefore, during the reciprocating rotation of the mounting rod, the sleeve can slide reciprocally along the length of the mounting rod, driving the spray gun to reciprocate synchronously.

[0017] Optionally, a guide block is provided on the side wall of the mounting rod, and a guide groove is provided on the inner wall of the sleeve, with the guide block extending into the guide groove.

[0018] By adopting the above technical solution, the sleeve can slide stably on the outer wall of the mounting rod under the action of the guide block and the guide groove.

[0019] Optionally, the end of the cantilever arm away from the frame is connected to a mounting bracket, the mounting bracket is equipped with a hollow connecting cylinder, the bracket is equipped with a plug rod that slides into the connecting cylinder, and a reset member is installed inside the connecting cylinder. When the power assembly drives the plug rod to slide into the connecting cylinder, the reset member is compressed.

[0020] By adopting the above technical solution, the insertion rod is inserted into the connecting cylinder, thereby realizing the sliding installation of the bracket on the cantilever arm. When the power component drives the bracket to move, the reset component provides the reset force for the bracket.

[0021] Optionally, a support plate is provided at one end of the slide plate near the frame, and the support plate abuts against the lower surface of the cantilever beam.

[0022] By adopting the above technical solution, a support plate is installed on the skateboard, and the support plate abuts against the lower surface of the cantilever arm, so that the support plate can provide a certain degree of support for the cantilever arm and improve the stability of the cantilever arm.

[0023] Optionally, the power assembly includes a first element mounted on the frame and a connector connecting the first element and the support, wherein the first element is capable of driving the connector to move toward the frame.

[0024] By adopting the above technical solution, the first element pulls the bracket towards the machine frame through the connector. When the pulling force on the bracket is removed, the bracket can be reset under the action of the reset component.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. During the painting process, the movement of the sliding plate drives the movement of the container, allowing the painting components to gradually enter the container and paint the inner wall of the container. During the painting process, the power component drives the support to reciprocate. During the reciprocating movement of the support, the linkage structure can drive the mounting rod to rotate back and forth, causing the angle of the spray gun to change back and forth. Moreover, the speed of the support's reciprocating movement is greater than the speed of the sliding plate, allowing the spray gun to spray paint towards the inner wall of the groove, thereby improving the painting effect of the inner wall of the container.

[0027] 2. During the reciprocating rotation of the mounting rod, the sleeve can reciprocate along the axis of the mounting rod, thereby further increasing the coverage area of ​​the spray gun and thus improving the painting efficiency. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a container painting apparatus. (Refer to...) Figure 1 The painting device includes a frame 3, a painting assembly 2 mounted on the frame 3, and a sliding plate 1. A slide rail is fixed to the ground, and the sliding plate 1 is slidably mounted on the slide rail. The sliding plate 1 can be driven to slide on the slide rail via chain transmission or other means. In other embodiments, the sliding plate 1 can also be pulled and slid by a winch. The container to be painted is placed on the sliding plate 1, with the opening of the container facing one side of the frame 3. The sliding plate 1 slowly moves towards the frame 3, and the painting assembly 2 gradually enters the container to paint the inner wall of the container.

[0036] The frame 3 includes a frame body 31 and a cantilever arm 32 mounted on the frame body 31, extending horizontally. The cantilever arm 32 has a certain length. To improve the stability of the frame body 31, counterweights are installed on the frame body 31, and the cantilever arm 32 is a steel truss structure reinforced by cables. A painting assembly 2 is installed at the end of the cantilever arm 32 furthest from the frame 3. The sliding direction of the slide plate 1 is parallel to the length direction of the cantilever arm 32, allowing the cantilever arm 32 to be projected orthogonally onto the sliding path of the slide plate 1. This allows the cantilever arm 32 to insert into the interior of the container when the slide plate 1 slides closer to the frame 3.

[0037] Reference Figure 2 and Figure 3A mounting bracket 15 is fixed to the end of the cantilever arm 32 away from the frame 3. The painting assembly 2 includes a bracket 21 slidably mounted on the mounting bracket 15, a mounting rod 22 mounted on the bracket 21, and a spray gun 23 mounted on the mounting rod 22. Multiple spray guns 23 are spaced apart along the length of the mounting rod 22. In this embodiment, the mounting rod 22 is mainly installed on both sides and the top of the bracket 21, enabling the spray guns 23 to paint the sides and top of the container. A power assembly 4 is installed between the frame 3 and the bracket 21, and the power assembly 4 drives the bracket 21 to reciprocate along the length of the cantilever arm 32.

[0038] In a further embodiment, the power assembly 4 includes a first element 41 mounted on the frame 3, and a connector 42 connecting the first element 41 and the support 21. Preferably, the connector 42 is a steel cable, and the first element 41 can be an electric telescopic cylinder. One end of the steel cable is connected to the support 21, and the other end is connected to the electric telescopic cylinder, which can pull the support 21 to slide via the steel cable. The first element 41 can also be a cylinder, lead screw, or other device capable of pulling the support 21 reciprocating.

[0039] Mounting rod 22 is rotatably mounted on bracket 21, and a linkage structure 5 is installed between cantilever arm 32 and mounting rod 22. When bracket 21 slides back and forth on cantilever arm 32, linkage structure 5 can drive mounting rod 22 to rotate back and forth, thereby enabling spray gun 23 to move back and forth. During painting, the sliding speed of slide plate 1 is less than the reciprocating speed of bracket 21, allowing spray gun 23 to paint the inner wall of the groove from different angles, thus improving the painting effect on the groove.

[0040] In a further embodiment, rotating seats 6 are rotatably mounted on the outer walls of both ends of the mounting rod 22, and the rotating seats 6 are fixed to the bracket 21. The linkage structure 5 includes an abutment strip 51 mounted on the cantilever beam 32 and an abutment wheel 52 coaxially mounted on the outer wall of the mounting rod 22. The abutment strip 51 and the abutment wheel 52 correspond one-to-one, and the abutment wheel 52 can abut against the abutment strip 51. When the bracket 21 slides on the cantilever beam 32, due to the frictional resistance between the abutment wheel 52 and the abutment strip 51, the abutment wheel 52 can rotate, thereby driving the mounting rod 22 to rotate, so that the orientation of the spray gun 23 changes as the bracket 21 slides back and forth.

[0041] Furthermore, refer to Figure 4 and Figure 5The surface of the abutment strip 51 is provided with a first friction section 7 and two second friction sections 8, with the first friction section 7 located between the two second friction sections 8. The frictional resistance between the abutment wheel 52 and the first friction section 7 is less than the resistance between the abutment wheel 52 and the second friction section 8. Therefore, when the bracket 21 is moving, when the abutment wheel 52 and the first friction section 7 abut together, the abutment wheel 52 can drive the mounting rod 22 to rotate synchronously; and when the abutment wheel 52 moves to the second friction section 8, the resistance between the abutment wheel 52 and the second friction section 8 decreases, which can decelerate the mounting rod 22. When the bracket 21 moves in one direction and stops, the mounting rod 22 and the spray gun 23 do not stop suddenly, but gradually stop, thereby reducing the inertial force acting on the cantilever arm 32 and improving the stability of the cantilever arm 32.

[0042] Connecting cylinders 16 are fixed at each of the four corners of the mounting bracket 15, with the connecting cylinders 16 located on the side closest to the frame 3. Insert rods 17 are fixed on the bracket 21 at positions corresponding to the connecting cylinders 16, and the insert rods 17 are slidably inserted into the connecting cylinders 16, allowing the bracket 21 to be slidably mounted on the mounting bracket 15. A reset element 18, which is a spring, is also installed inside the connecting cylinder 16. One end of the spring is connected to the inner end face of the connecting cylinder 16, and the other end is connected to the end face of the insert rod 17. When the steel cable pulls the bracket 21 towards the frame 3, the reset element 18 is compressed, providing a force for the bracket 21 to move away from the frame 3, thus enabling the bracket 21 to reciprocate.

[0043] Reference Figure 4 and Figure 5 Furthermore, a sleeve 9 is slidably mounted on the outer wall of the mounting rod 22. A guide groove 14 is formed on the inner wall of the sleeve 9, and a guide block 13 is fixed on the side wall of the mounting rod 22, extending into the guide groove 14. This allows the sleeve 9 to slide along the length direction of the mounting rod 22, and the rotation of the mounting rod 22 synchronously drives the sleeve 9 to move. The spray gun 23 is mounted on the sleeve 9, and a trigger element 10 is installed between the sleeve 9 and the rotating seat 6. When the mounting rod 22 reciprocates, the sleeve 9 can slide reciprocally along the length direction of the mounting rod 22, thereby allowing the orientation position of the spray gun 23 to reciprocate along the length direction parallel to the mounting rod 22, further improving the painting effect.

[0044] In a further embodiment, an elastic element 11, which is a spring, is installed between the sleeve 9 and the mounting rod 22. An annular protrusion 20 is provided on the outer wall of the mounting rod 22 near one of the rotating seats 6, and a stepped edge is provided on the inner wall of the sleeve 9 near the annular protrusion 20. One end of the spring is connected to the annular protrusion 20, and the other end is connected to the inner wall of the sleeve 9. A protrusion 12, which has an arc-shaped structure, is fixed on the end face of the sleeve 9 away from the elastic element 11. The trigger element 10 includes a trigger block 101 fixed to the side of the rotating seat 6 facing the protrusion 12. The end of the trigger block 101 facing the sleeve 9 also has an arc-shaped structure, and multiple trigger blocks 101 are spaced apart along the circumference of the rotating seat 6. When the mounting rod 22 drives the sleeve 9 to rotate, the protrusion 12 can abut against the trigger block 101 and drive the sleeve 9 to move towards the elastic element 11. At this time, the elastic element 11 is compressed. When the protrusion 12 and the trigger block 101 disengage, the sleeve 9 can slide towards the trigger block 101. The reciprocating rotation of the mounting rod 22 achieves the reciprocating sliding of the sleeve 9.

[0045] Reference Figure 1 In a further embodiment, a support plate 19 is vertically fixed to the upper surface of the slide plate 1 near the frame 3. The support plate 19 abuts against the lower surface of the cantilever arm 32, thereby supporting the cantilever arm 32 and further improving its stability. A groove can be formed on the support plate 19 corresponding to the cantilever arm 32, and rotatable ball bearings are connected to the inner wall of the groove to reduce friction between the cantilever arm 32 and the support plate 19.

[0046] The implementation principle of the container painting device in this application embodiment is as follows: In the initial state, the spray gun 23 is tilted towards the frame 3. During painting, the slide plate 1 moves towards the frame 3, and the cantilever arm 32 gradually extends into the container. The sliding speed of the slide plate 1 is less than the reciprocating speed of the support 21. The reciprocating movement of the support 21 allows the spray gun 23 to reciprocate and adjust the spray angle, thereby painting the grooved parts on the inner wall of the container from different angles, improving the painting effect. Furthermore, during the reciprocating rotation of the mounting rod 22, the spray gun 23 can also reciprocate and slide along the length of the mounting rod 22, further improving the uniformity of the paint spraying.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
