Description

Technical Field

[0001] The utility model relates to the technical field of safety helmet painting, in particular to an automatic safety helmet painting device. Background Technique

[0002] A safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. A safety helmet consists of a hat shell, a hat lining, a chin strap and accessories, etc. During the production process of safety helmets, it is necessary to use a painting device for painting and coloring. Spraying is a painting method that uses a spray gun or a disc atomizer to disperse into uniform and fine droplets by means of pressure or centrifugal force and apply them to the surface of the object to be painted.

[0003] For example, the Chinese utility model patent with the publication number CN219631695U discloses a safety helmet painting and coloring device, including a base and a frame. The top of the base is provided with a processing table through a rotating mechanism, and a grid plate is fixedly connected to the top of the processing table. A collection box is movably connected to the bottom of the inner wall of the processing table. A painting mechanism is arranged below the frame. The painting mechanism includes an annular shell, and a first paint spraying head is fixedly connected to the inner wall of the annular shell. This utility model relates to the technical field of safety helmet production. In this safety helmet painting and coloring device, a painting mechanism is arranged below the frame. The hydraulic cylinder drives the annular shell to move downward, and a plurality of annularly distributed first paint spraying heads spray uniformly on the periphery of the safety helmet from top to bottom. The second paint spraying head at the top sprays on the top of the safety helmet. At the same time, the safety helmet rotates driven by a motor, improving the uniformity during painting, automatically spraying the safety helmet all-round and quickly, saving time and effort, and improving the processing efficiency.

[0004] However, there are still some problems. Although the safety helmet rotates driven by a motor, improving the uniformity during painting, automatically spraying the safety helmet all-round and quickly, saving time and effort, and improving the processing efficiency, it is impossible to spray the inner wall of the safety helmet, which is a bit inconvenient. Therefore, an automatic safety helmet painting device is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an automatic safety helmet painting device, which has the advantage of a large spraying range and solves the problem that the inner wall of the safety helmet cannot be sprayed.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An automatic paint spraying device for safety helmets, comprising a support frame, a bottom plate is fixed to the top of the support frame, a protective cover is fixed to the top of the bottom plate, a driving motor is fixed to the top of the support frame, an output shaft of the driving motor is fixed with a fixing component penetrating to the top of the bottom plate, the fixing component is used to support the safety helmet, a lateral movement component is arranged on the rear side wall of the inner cavity of the protective cover, and a vertical movement component is arranged on the front side of the lateral movement component;

The output shaft of the driving motor is fixed with the fixing rod penetrating to the top of the bottom plate. The outer surface of the fixing rod is fixed with the fixing frames. The outer surface of the fixing frames is fixed with the fixing blocks. The positioning springs are fixed inside the fixing blocks. One side of the positioning spring away from the fixing rod is fixed with the positioning blocks, and the positioning blocks penetrate to the outside of the fixing blocks.

[0009] By adopting this technical solution, when placing the safety helmet, the positioning blocks will be squeezed, so that the positioning springs generate prestress, and the positioning blocks are pushed to position the safety helmet. In addition, it should be noted that the rotation speed of the driving motor is not high, and the supporting points of the positioning blocks are on the left and right sides of the inner cavity of the safety helmet.

[0010] Further, the vertical movement component includes a mounting block, a rotating motor, a rotating rod and a moving block. The mounting block is fixed to the lateral movement component.

[0034] Please refer to Figure 3 , in this embodiment, the fixing component 5 includes a fixing rod 501, three fixing frames 502, three fixing blocks 503, three positioning springs 504 and three positioning blocks 505. The output shaft of the driving motor 4 is fixed to the fixing rod 501 penetrating through the top of the bottom plate 2.

The provided fixing bearing enables the rotation of the fixing rod 501 to be more stable. The outer surface of the fixing rod 501 is fixed to the fixing frame 502, the outer surface of the fixing frame 502 is fixed to the fixing block 503, the inside of the fixing block 503 is fixed to the positioning spring 504, and the side of the positioning spring 504 away from the fixing rod 501 is fixed to the positioning block 505.

In addition, it should be noted that the rotation speed of the driving motor 4 is not high, and the supporting points of the positioning block 505 are on the left and right sides of the inner cavity of the safety helmet.

[0036] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.

[0037] The working principle of the above embodiment is as follows:

[0038] When the safety helmet is placed on the top of the fixing frame 502, it will cause the safety helmet to squeeze the positioning block 505, so that the positioning block 505 moves into the inside of the fixing block 503, squeezing the positioning spring 504, causing the positioning spring 504 to generate a certain prestress, so that the positioning spring 504 pushes the fixing block 503 into contact with the inner cavity of the safety helmet and supports the safety helmet, thus completing the support and positioning of the safety helmet. At this time, starting the drive motor 4 can make the fixing rod 501 and the safety helmet rotate. By starting the air pump 12, air flow can be generated in the connecting pipe 13 to clean the outer surface of the safety helmet. When the adjusting motor 602 rotates, it will cause the adjusting rod 603 to rotate, and then the adjusting block 604 moves due to the extrusion of the thread, driving the vertical moving assembly 7 to move. When the rotating motor 702 operates, the rotating rod 703 can be rotated, and then the moving block 704 drives the self-rotating spray head 8 to move, so that the self-rotating spray head 8 can move in multiple directions. By starting the air pump 12, the paint in the storage box 11 can be drawn into the inside of the self-rotating spray head 8 through the connecting pipe 13 to complete painting. The overall structure is simple and the safety helmet can be painted in multiple directions, making the whole more practical.
