Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, and more specifically, to a support device for tank circumferential spraying. Background Technology

[0002] In the manufacturing of tank products, painting is a necessary process to enhance the appearance and durability of the tanks. Painting is a crucial step in determining the overall quality of the product's appearance. Tank painting involves atomizing paint using a spray gun or automated equipment and applying it to the tank surface to form a protective or decorative coating.

[0003] There are many problems with current tank painting processes. Current painting equipment requires the tank to be placed on a platform for painting the outer wall. This method can only paint the outer wall and cannot simultaneously paint the bottom. It requires two separate processes, and the bottom can only be painted after the paint on the outer wall is dry. This process is time-consuming. Painting the bottom will affect the already finished paint on the outer wall. Moreover, the second painting can cause differences in paint between the bottom and the outer wall. Some painting operations still rely on manual operation. The rotation of the platform and the painting are greatly affected by the operator's technique. It is difficult for humans to accurately control the consistency of the spraying, resulting in uneven paint on the tank and a rough surface, which affects the quality of the final product.

[0004] In view of the shortcomings of the above-mentioned tank painting process, it is necessary to develop a new improved structure for tank painting that can be adapted to the painting process of tanks of different specifications and achieve full painting of the tank, thereby improving the quality of the finished product. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the current ceramic spray painting process and to provide a support device for ring spraying of tanks, so as to achieve the effect of convenient, comprehensive and uniform ring spraying.

[0042] First embodiment:

[0043] In this embodiment, a support device for tank ring spraying includes a lifting and rotating mechanism 1, a support mechanism 2, and a placement base 3 mounted on a base frame. The lifting and rotating mechanism 1 and the support mechanism 2 are positioned above the placement base 3. The support mechanism 2 is installed at the lower end of the lifting and rotating mechanism 1. The lifting and rotating mechanism 1 includes a lifting drive unit 4 and a rotating drive unit 5. The rotating drive unit 5 is mounted on the lifting connecting rod 41 of the lifting drive unit 4. The support mechanism 2 includes a telescopic drive unit 6 and a telescopic support unit 7. The telescopic drive unit 6 controls the telescopic movement of the telescopic support unit 7. The telescopic support unit 7 is telescopically mounted at the lower end of the lifting connecting rod 41 of the lifting drive unit 4. A plurality of telescopic support units 7 are equidistantly arranged in a ring on the outer side of the lower end of the lifting connecting rod 41. A placement panel 8 is provided above the placement base 3.

[0044] Preferably, in this embodiment, the telescopic drive unit 6 is connected to the pressure feedback control unit, the pressure detection part of the pressure feedback control unit is disposed in the telescopic support unit 7, and the pressure feedback control unit controls the telescopic drive limit of the telescopic drive unit 6.

[0045] Preferably, in this embodiment, the lower end of the support mechanism 2 is provided with a bottom distance sensor 21, and the bottom distance sensor 21 is connected to the lifting drive unit 4.

[0046] Preferably, in this embodiment, three telescopic support units 7 are arranged in a ring at equal intervals on the outer side of the lower end of the lifting link 41.

[0047] Preferably, in this embodiment, the telescopic support unit 7 includes a segmented telescopic link 71 and a support plate 72 disposed at the outer support end of the segmented telescopic link 71. The support plate 72 is concave arc-shaped, and the outer contact surface of the support plate 72 is provided with elastic friction protrusions 74. The segmented telescopic link 71 is connected to the telescopic drive unit 6.

[0048] Preferably, in this embodiment, the lower end of the lifting and rotating mechanism 1 is provided with a tank extension monitoring part 11, the detection and acquisition direction of the tank extension monitoring part 11 is toward the telescopic support unit 7, and the tank extension monitoring part 11 is connected to the lifting drive unit 4.

[0049] Preferably, in this embodiment, the upper surface of the placement panel 8 is provided with two mutually perpendicular intersecting positioning grooves 81 forming an X shape. The intersection of the positioning grooves 81 is aligned with the axis of the lifting and rotating mechanism 1, and a plurality of concentric positioning annular grooves 82 are provided outward from the intersection with the positioning grooves 81.

[0050] Place the can products to be ring-sprayed onto the placement panel 8. The X-shaped positioning grooves 81, which intersect perpendicularly, intuitively place the products in the center. Combined with the concentric positioning ring grooves 82, the accuracy of the product placement is improved. The intersection of the concentric positioning ring grooves 82 and the positioning grooves 81 can also help operators to more easily and accurately judge and adjust the placement of square or other shaped products to the ideal center position.

[0051] The operator starts the device, activating the lifting and rotating mechanism 1 and the tank insertion monitoring unit 11. The tank insertion monitoring unit 11 monitors the insertion status of the telescopic support unit 7 of the support mechanism 2. The lifting drive unit 4 drives the support mechanism 2 to descend towards the opening of the tank and extend into the product. The telescopic drive unit 6 drives the three equidistantly arranged telescopic support units 7 to extend outward synchronously. The segmented telescopic connecting rod 71 drives the support plate 72 to abut against the inner wall of the tank. The concave arc-shaped support plate 72 fits against the inner wall of the tank. The elastic friction protrusion 74 on the outer contact surface of the support plate 72 increases the friction between the support plate 72 and the inner wall of the tank, completing the support. The lifting drive unit 4 rises, causing the supported tank to rise synchronously, leaving sufficient painting space between the bottom of the tank and the placement platform 3. The rotation drive unit 5 starts and rotates at a low and uniform speed according to the preset speed, causing the tank to rotate and perform a comprehensive and uniform ring spraying process on the tank to achieve a uniform painting effect.

[0052] When the telescopic support unit 7 extends into the tank opening, if the tank extension monitoring unit 11 detects a misalignment between the telescopic support unit 7 and the opening, it will control the lifting drive unit 4 to stop descending and rise to reset. After the support mechanism 2 extends into the tank, the bottom distance sensor 21 at the lower end of the support mechanism 2 detects the distance between the bottom of the support mechanism 2 and the bottom of the tank. When the distance between the bottom of the support mechanism 2 and the bottom of the tank reaches a preset minimum value, the bottom distance sensor 21 controls the lifting drive unit 4 to stop, and the support mechanism 2 performs a supporting action.

[0053] Second embodiment:

[0054] This embodiment is similar to the first embodiment, except that the number of telescopic support units 7 is set to three, the included angle between each telescopic support unit 7 is set to 120°, and the telescopic support unit 7 is inclined upwards at an angle of 2°-5°. This upward inclination improves the support and fixation effect of the telescopic support unit 7 on the tank, ensures a close fit between the telescopic support unit 7 and the tank, and prevents slippage during lifting and rotation, which could lead to uneven ring spraying and affect the quality of the finished product.

[0055] Third embodiment:

[0056] This embodiment is similar to the first embodiment, except that the telescopic support unit 7 in this embodiment includes an inflatable support balloon 75, which is connected to the inflation part of the telescopic drive unit 6, and the outer end face of the inflatable support balloon 75 is provided with friction protrusions 76.

[0057] When processing using this embodiment, the operator starts the device, the lifting and rotating mechanism 1 and the tank insertion monitoring unit 11 are activated. The tank insertion monitoring unit 11 monitors the insertion status of the telescopic support unit 7 with the inflatable support balloon 75. The lifting drive unit 4 drives the support mechanism 2 to descend toward the opening of the tank and extend into the product. The inflation part of the telescopic drive unit 6 drives the inflatable support balloon 75 of the telescopic support unit 7 to inflate and extend outward simultaneously. The inflatable support balloon 75 expands and its outer wall abuts against the inner wall of the tank and fits snugly. The friction protrusion 76 on the outer end face of the inflatable support balloon 75 increases the friction between the support plate 72 and the inner wall of the tank, completing the support process. The lifting drive unit 4 rises and drives the tank, which is supported by the inflatable support balloon 75, to rise synchronously, leaving sufficient painting space between the bottom of the tank and the placement platform 3. The rotation drive unit 5 starts and rotates at a low and uniform speed according to the preset speed, causing the tank to rotate slowly. The painting operation equipment performs a comprehensive and uniform ring spraying process on the tank to achieve a uniform painting effect.

[0058] Fourth embodiment:

[0059] This embodiment is similar to the first embodiment, except that the placement base 3 in this embodiment is equipped with a platform lifting unit 9, and the placement panel 8 is installed on the upper end of the platform lifting unit 9. For products with a high height or those that cannot be raised high enough after support, after the support mechanism 2 completes the support of the can, the lifting and rotating mechanism 1 rises, and at the same time, the platform lifting unit 9 can be controlled to descend. The platform lifting unit 9 drives the placement panel 8 to descend synchronously, so that more painting space is left between the upper surface of the placement panel 8 and the bottom of the can. Sufficient space is left for the outer wall and bottom of the can for the ring painting process without the lifting and rotating mechanism 1 needing to rise too high, so that the full painting process of the can product can continue.
