Description

Technical Field

[0001] This application relates to the field of pressure vessel production equipment technology, and more specifically, to a surface painting device for the production of pressure storage tanks. Background Technology

[0002] The quality of the paint on the outer surface of liquefied petroleum gas (LPG) cylinders determines the overall quality of the LPG cylinder production. If the paint on the outer surface of the LPG cylinder is of poor quality, the cylinder body is prone to corrosion, which can lead to LPG leaks and even accidents such as fires or explosions.

[0003] A search revealed that the publication (announcement) number CN217341972U discloses "a surface painting device for the production of pressure storage tanks, including a base, two sets of side supports fixedly connected to the base, a back plate fixedly connected to one side of the base, and also includes: a clamping component; a control component; a drive component... This utility model realizes simultaneous automatic painting of multiple sets of bottles, improves the painting quality of the device, reduces labor costs, and improves the working efficiency of the device." However, this application does not have a drying function, which means that the pressure vessel is disassembled and air-dried after painting, but the efficiency of natural air drying is low. Alternatively, it can be disassembled and transferred to another drying device for drying, but such operation is cumbersome and time-consuming.

[0004] To address the aforementioned problems, this application provides a surface painting apparatus for the production of pressure storage tanks. Utility Model Content

[0005] One objective of this application is to provide a surface painting device for the production of pressure gas storage tanks, comprising a painting device body, a support plate fixedly connected to the surface of the painting device body, a groove formed on the surface of the support plate, a rotating column rotatably connected inside the groove, a rotating plate fixedly connected to the outside of the rotating column, a second motor for driving the rotating column to rotate fixedly connected to the top of the support plate, an electric push rod fixedly connected to the surface of the rotating plate, the output end of the electric push rod penetrating the inner cavity of the rotating plate and connected to a lifting assembly, a plurality of connecting plates provided on the surface of the lifting assembly, an air outlet box fixedly connected to the top of the connecting plates, a plurality of air outlet holes formed on the surface of the air outlet box, a fixed pipe connected to the air outlet box, a hot air blower fixedly connected to the surface of the rotating plate, a connecting pipe fixedly connected to the hot air blower, and three flexible hoses fixedly connected between the connecting pipe and the three air outlet boxes.

[0006] Furthermore, the lifting assembly includes a movable plate fixedly connected to the output end of the electric push rod. A sliding groove is formed on the surface of the movable plate. A lead screw is rotatably connected inside the sliding groove. A sliding plate is slidably connected inside the sliding groove, and the sliding plate is threaded onto the outside of the lead screw. A first motor for driving the lead screw to rotate is fixedly connected to the top of the movable plate.

[0007] Furthermore, the connecting plate is fixedly connected to the sliding plate, and a receiving plate is fixedly connected to the bottom of the connecting plate.

[0008] Furthermore, the upper and lower end faces of the sliding plate are on the same horizontal plane as the opposite sides of the two non-adjacent connecting plates, and the hot air blower is located on the right side of the electric push rod.

[0009] Furthermore, the multiple air outlets are arranged in a rectangular array, the longitudinal section of the receiving plate is set in a semi-circular shape, and the receiving plate and the connecting plate are integrally formed.

[0010] Furthermore, a support base is fixedly connected to the surface of the paint spraying device body, a groove is provided on the top of the support base, and a limit rod is fixedly connected to the bottom end face of the rotating plate, with the lower end of the limit rod extending into the interior of the groove.

[0011] The beneficial effects of this application are:

[0012] 1. Control the second motor to drive the rotating column to rotate, which in turn drives the rotating plate to rotate, making the rotating plate parallel to the front face of the support base. This ensures that the air outlet box and the receiving plate are parallel to the clamped pressure vessel. Then, control the lifting assembly and the electric push rod to adjust the air outlet box to the appropriate position. Control the hot air blower to deliver hot air to the interior of the three air outlet boxes through the connecting pipe, three flexible hoses, and three fixed pipes. The hot air is then discharged through the air outlet to dry the paint on the surface of the pressure vessel. At the same time, control the painting device to drive the clamped pressure vessel to rotate, achieving uniform drying of the pressure vessel. Thus, painting and drying can be carried out on one machine without disassembly, transportation, and reinstallation, improving work efficiency.

[0013] 2. This application facilitates the simultaneous removal of the dried pressure vessel and also facilitates the simultaneous installation and fixing of multiple pressure vessels. Attached Figure Description

[0025] Example:

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a surface painting device for the production of pressure gas storage tanks, including a painting device body 1. The painting device body 1 is a prior art device, which can simultaneously and automatically paint multiple groups of bottles, thereby improving work efficiency. Its structure and working principle are based on the surface painting device for the production of pressure gas storage tanks disclosed in CN217341972U, and will not be described in detail here. A support plate 3 is fixedly connected to the surface of the painting device body 1. A groove is formed on the surface of the support plate 3. A rotating column 10 is rotatably connected inside the groove. A rotating plate 11 is fixedly connected to the outside of the rotating column 10. The support plate 3... A second motor 9 is fixedly connected to the top of the rotating column 10 to drive the rotating column 10 to rotate. The second motor 9 is controlled to work to drive the rotating column 10 to rotate. The rotation of the rotating column 10 drives the rotating plate 11 to rotate, so that the rotating plate 11 after rotation is parallel to the front end face of the support base 2, thereby making the air outlet box 12 parallel to the clamped pressure vessel. An electric push rod 18 is fixedly connected to the surface of the rotating plate 11. The electric push rod 18 can adjust the position of the air outlet box 12 and the receiving plate 14. The output end of the electric push rod 18 passes through the inner cavity of the rotating plate 11 and is connected to a lifting assembly. Multiple connecting plates 13 are provided on the surface of the lifting assembly.

[0027] An air outlet box 12 is fixedly connected to the top of the connecting plate 13. Multiple air outlet holes 19 are opened on the surface of the air outlet box 12. A fixed pipe 15 is connected to the air outlet box 12. A hot air blower 17 is fixedly connected to the surface of the rotating plate 11. The hot air blower 17 is controlled to work to deliver hot air to the inside of the three air outlet boxes 12 through the cooperation of the connecting pipe 6, three hoses 16 and three fixed pipes 15. Then, the hot air is discharged through the air outlet holes 19 to dry the paint on the surface of the pressure vessel. A connecting pipe 6 is fixedly connected to the hot air blower 17. Three hoses 16 are fixedly connected between the connecting pipe 6 and the three air outlet boxes 12. The multiple air outlet holes 19 are arranged in a rectangular array. The longitudinal section of the receiving plate 14 is set in a semi-ring shape. The receiving plate 14 and the connecting plate 13 are integrally formed.

[0028] Please see Figure 1 , Figure 2 and Figure 3The lifting assembly includes a movable plate 7 fixedly connected to the output end of an electric push rod 18. A sliding groove 22 is provided on the surface of the movable plate 7. A lead screw 20 is rotatably connected inside the sliding groove 22. A sliding plate 21 is slidably connected inside the sliding groove 22, and the sliding plate 21 is threaded onto the outside of the lead screw 20. A first motor 8 for driving the lead screw 20 to rotate is fixedly connected to the top of the movable plate 7. The output end of the first motor 8 passes through the top of the movable plate 7 and is fixedly connected to the top end of the lead screw 20. Controlling the first motor 8 to work drives the lead screw 20 to rotate. The rotation of the lead screw 20 drives the sliding plate 21 to move inside the sliding groove 22. The movement of the sliding plate 21 can drive the three connecting plates 13 to move, thereby facilitating the height adjustment of the receiving plate 14 and the air outlet box 12. The upper and lower end faces of the sliding plate 21 are on the same horizontal plane as the opposite sides of two non-adjacent connecting plates 13. The hot air blower 17 is located on the right side of the electric push rod 18.

[0029] Please see Figure 1 and Figure 2 The connecting plate 13 is fixedly connected to the sliding plate 21. The bottom of the connecting plate 13 is fixedly connected to the receiving plate 14, which can support the pressure vessel and facilitate the disassembly and removal of the pressure vessel.

[0030] Please see Figure 1 A support base 2 is fixedly connected to the surface of the paint spraying device body 1. A groove 4 is provided on the top of the support base 2. A limit rod 5 is fixedly connected to the bottom end of the rotating plate 11. The lower end of the limit rod 5 extends into the interior of the groove 4. When the second motor 9 drives the rotating plate 11 to rotate, the rotating plate 11 drives the limit rod 5 to rotate inside the groove 4, thereby further improving the stability of the rotating plate 11 when rotating.

[0031] The implementation principle of this application embodiment is as follows: During drying, the second motor 9 is controlled to drive the rotating column 10 to rotate, and the rotating column 10 drives the rotating plate 11 to rotate, so that the rotating plate 11 after rotation is parallel to the front end face of the support seat 2, thereby making the air outlet box 12 and the receiving plate 14 parallel to the pressure container being held. Then, the lifting assembly and the electric push rod 18 are controlled to adjust the air outlet box 12 to a suitable position, so that the receiving plate 14 is not located below the pressure container, avoiding paint from falling into the inside of the receiving plate 14. Then, the hot air blower 17 is controlled to deliver hot air to the inside of the three air outlet boxes 12 through the cooperation of the connecting pipe 6, three hoses 16 and three fixed pipes 15, and then discharged through the air outlet 19 to dry the paint on the surface of the pressure container. At the same time, the paint spraying device body 1 is controlled to drive the pressure container being held to rotate, so as to achieve uniform drying of the pressure container.

[0032] After drying is complete, the lifting assembly is controlled to move the receiving plate 14 to a position below the pressure vessel. Then, the electric push rod 18 is controlled to move the receiving plate 14 so that it is directly below the pressure vessel. Next, the lifting assembly is controlled to move the receiving plate 14 upward to contact the outside of the pressure vessel. Then, the spray painting device body 1 is controlled to release the pressure vessel from its fixation. At this time, the pressure vessel is supported by the receiving plate 14. Then, the second motor 9 is controlled to reverse, causing the rotating plate 11 to rotate the receiving plate 14 to a certain angle, thereby rotating the pressure vessel to one side of the spray painting device body 1. Then, the operator removes the dried pressure vessel and places the next pressure vessel to be dried inside the receiving plate 14. The second motor 9 is then controlled to rotate the rotating plate 11 so that it is parallel to the front end of the support base 2, thus rotating the pressure vessel inside the spray painting device body 1. Finally, the spray painting device body 1 is controlled to clamp and fix the pressure vessel for the next painting operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
