[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] See also Figures 1-10 The present invention provides a technical solution: a self-adaptive adjustable multi-directional precision paint spraying machine for helmet production, comprising a base 1, a hydraulic column 2, an arc-shaped bracket 3, a gear turntable 4, an electric drive bevel gear 5, a positioning frame 6, a hydraulic lifting column 7, an electric drive slide plate 8, a steering paint spray gun 9, a connecting pipe 10, a telescopic pipe 11, a positioning frame 2 12, a ball screw 13, a limit slide 14, a hydraulic lifting column 2 15, a ventilation frame 16, a double-layer telescopic sleeve 17 and a spring lifting sleeve 18;

[0044] Among them, the base 1 is a strip frame structure, and two hydraulic columns 2 are symmetrically arranged on the upper end of the base 1, and an arc-shaped bracket 3 is fixedly installed on the output end of the hydraulic column 2. A steering spray gun 9 is provided below the arc-shaped bracket 3, and the steering spray gun 9 is the main spraying equipment for spraying the helmet;

[0045] An opening is provided in the arc-shaped bracket 3, and a gear turntable 4 is rotatably connected in the opening of the arc-shaped bracket 3, and the gear turntable 4 consists of an annular gear ring and two arc-shaped pieces. The annular gear ring of the gear turntable 4 is meshed with the bevel gear at the output end of the electric drive bevel gear 5. A positioning frame 6 is sleeved on the annular gear ring of the gear turntable 4, and the positioning frame 6 is penetrated by a hydraulic lifting column 7. The two arc-shaped pieces of the gear turntable 4 slide in the opening of the arc-shaped bracket 3, and the curvature of the arc-shaped piece of the gear turntable 4 is consistent with the curvature of the arc-shaped bracket 3. The output end of the hydraulic lifting column 7 is connected to the disc structure by bolts, and the disc connected to the hydraulic lifting column 7 is positioned and connected to the electric drive slide plate 8 by bolts. A sliding trolley is slidably connected in the slide rail of the electric drive slide plate 8, and the sliding trolley of the electric drive slide plate 8 is connected to the steering paint spray gun 9 through a rotating rod bracket;

[0046] Combined with the drawings in the specification Figures 1-10 As shown, the operator controls the hydraulic system of the hydraulic column 2 through the control system according to the overall height of the helmet and the painting requirements. The output end of the hydraulic column 2 is extended and retracted, driving the arc-shaped bracket 3 to rise or fall, so as to adjust the overall painting height and ensure that the steering spray gun 9 maintains a suitable vertical distance from the helmet. The electric drive bevel gear 5 is started, and the motor drives the bevel gear to rotate. Since the annular gear ring of the gear turntable 4 in the opening of the arc bracket 3 is engaged with the bevel gear at the output end of the electric drive bevel gear 5, according to the gear meshing principle, the gear turntable 4 rotates in the opening of the arc bracket 3, as shown in FIG. Figure 4-Figure 5 As shown, the rotation of the gear turntable 4 drives the components connected thereto to rotate, thereby realizing the horizontal angle adjustment of the steering paint spray gun 9, so that the steering paint spray gun 9 can spray paint on the surface of the helmet at a suitable angle. The steering paint spray gun 9 is installed on an electric lifting bracket, which adopts a motor-driven screw rod or chain transmission to convert the rotational motion of the motor into a linear lifting motion, thereby realizing the up and down movement of the paint spray gun to complete the reciprocating spraying work. When the gear turntable 4 rotates, its arc-shaped piece fits with the inner wall of the opening of the arc bracket 3, and a sealing strip or a protective cover structure is provided between the two. As the gear turntable 4 rotates, it gradually closes to form a sealed space, effectively preventing paint from splashing to other parts of the equipment.

[0047] The spraying of the helmet is carried out by starting the electric drive slide plate 8. The slider on the slide rail of the electric drive slide plate 8 rotates under the drive of the motor, driving the rotating rod bracket and the steering spray gun 9 to move in the horizontal direction. The operator adjusts the reciprocating motion of the slider of the electric drive slide plate 8 through the control system according to the shape of the helmet and the requirements of the painting process, so that the steering spray gun 9 sprays the surface of the helmet comprehensively and evenly in the horizontal direction. The sprayed paint is transported to the steering spray gun 9 through the external paint supply system through the telescopic tube 11, the connecting tube 10 and the hose. When the steering spray gun 9 is working, the paint is evenly sprayed on the surface of the helmet. In the process of the hydraulic lifting column 7 driving the electric drive slide plate 8 to rise and fall, the telescopic tube 11 adaptively adjusts the length to ensure smooth paint supply and ensure the continuity and stability of the painting process.

[0048] When the helmet is finished painting, close the paint supply valve of the steering spray gun 9 to stop the paint delivery. At the same time, turn off the motors of the electric drive bevel gear 5, the electric drive slide plate 8 and other components to stop the painting operation of the equipment. During actual use, the operator should regularly clean the steering spray gun 9, the connecting pipe 10, the telescopic pipe 11, the arc bracket 3 and other parts where paint is easily left to keep the equipment clean;

[0049] The electric drive slide plate 8 and the steering paint spray gun 9 are arranged in parallel up and down, and the steering paint spray gun 9 is above the spring lifting sleeve 18. The steering paint spray gun 9 is connected to the connecting pipe 10 through a hose, and the other end of the connecting pipe 10 is connected to the telescopic tube 11. There is a helmet support assembly under the steering paint spray gun 9, and the helmet support assembly includes a limiting slide 14, a hydraulic lifting column 2 15, a ventilation frame 16, a double-layer telescopic sleeve 17 and a spring lifting sleeve 18, wherein the limiting slide 14 is slidably connected in the base 1, a strip slide is provided on the upper end surface of the base 1, and a positioning frame 2 12 is respectively installed at both ends of the strip slide of the base 1, and a ball screw 13 is rotatably connected in the positioning frame 2 12, the connecting pipe 10 passes through the positioning frame 1 6 and the electric drive slide plate 8, and the connecting pipe 10 and the telescopic tube 11 are vertically arranged on the side wall of the hydraulic lifting column 1 7, the ball screw 13 passes through the limiting slide 14, and the upper end of the limiting slide 14 is connected to the hydraulic lifting column 2 15, and the output end of the hydraulic lifting column 2 15 is installed with a ventilation frame 16. A sliding rod is provided between the two limiting slides 14, and the limiting slide 14 and the hydraulic lifting column 2 15 are arranged in a vertical direction. The top of the ventilation frame 16 is connected to the spring lifting sleeve 18, and a cross-shaped pipe is provided in the ventilation frame 16, and a double-layer telescopic sleeve 17 is connected to the pipe of the ventilation frame 16. The double-layer telescopic sleeve 17 is a sleeve rod structure with a two-stage sliding connection, and a bellows is provided between the two sleeve rods of the double-layer telescopic sleeve 17, and the bellows of the double-layer telescopic sleeve 17 is connected to the pipe of the ventilation frame 16. The spring lifting sleeve 18 is a slide rod with a two-stage sliding connection, and a spring structure is provided between the slide rod structure of the spring lifting sleeve 18;

[0050] Combined with the drawings in the specification Figures 1-10 As shown, the helmet to be painted is placed above the spring lifting sleeve 18. At this time, the gravity of the helmet will cause the spring lifting sleeve 18 to descend, and the spring is compressed. During the descending process of the spring lifting sleeve 18, the gas in the internal bellows is squeezed out and filled into the ventilation frame 16. Then the gas enters the bellows of the double-layer telescopic sleeve 17, causing the double-layer sleeves of the double-layer telescopic sleeve 17 to expand. The silicone on the surface of the outer rod is in full contact with the inner layer of the helmet, and the positioning and fixation of the helmet is preliminarily achieved. The silicone on the outer wall of the spring lifting sleeve 18 and the double-layer telescopic sleeve 17 is used to increase the contact with the head. The helmet contacts friction to prevent the helmet from being overturned by the impact of the paint when spraying. The motor is started to drive the ball screw 13 in the positioning frame 12 to rotate. Since the ball screw 13 passes through the limiting slide 14, according to the principle of spiral transmission, the limiting slide 14 will make a linear motion on the strip slide rail of the base 1. The operator adjusts the rotation direction and speed of the motor through the control system according to the size of the helmet and the requirements of the painting process, and accurately adjusts the position of the limiting slide 14, thereby realizing the horizontal position adjustment of the helmet to ensure that the helmet is in a suitable painting position.

[0051] According to the height requirement of the helmet, the operator issues instructions through the control system to control the hydraulic system of the hydraulic lifting column 2 15. The output end of the hydraulic lifting column 2 15 is extended and retracted according to the instructions, driving the ventilation frame 16 as a whole to drive the helmet up or down, and then adjusting the vertical height of the helmet to make the helmet at a suitable painting height.

[0052] Working principle: When using the adaptive adjustable multi-directional precision paint spraying machine for helmet production, first, the helmet is placed on the spring lifting sleeve 18. The spring lifting sleeve 18 is lowered by gravity, causing the spring of the spring lifting sleeve 18 to drop, so that the bellows gas in the spring lifting sleeve 18 is filled into the ventilation frame 16, and the gas is then filled into the bellows of the double-layer telescopic sleeve 17. The double-layer sleeve of the double-layer telescopic sleeve 17 is expanded, so that the outer rod surface of the double-layer telescopic sleeve 17 is provided with silicone, which is in full contact with the inner layer of the helmet. The ball screw 13 in the positioning frame 12 is driven to rotate by the motor. Since the ball screw 13 passes through the limiting slide 14, according to the spiral transmission principle, the limiting slide 14 will make a linear motion on the bar slide, thereby realizing the horizontal position adjustment of the helmet to meet the fixing requirements of helmets of different sizes and the painting position requirements;

[0053] According to the height requirement of the helmet, the hydraulic system controls the extension and contraction of the output end of the hydraulic lifting column 2 15, driving the ventilation frame 16 to rise or fall, so that the helmet is at the appropriate painting height;

[0054] As the hydraulic column 2 is extended and retracted through the output end controlled by the hydraulic system, the arc bracket 3 is driven to rise or fall, and the overall painting height is adjusted. Since the gear turntable 4 in the opening of the arc bracket 3, its annular gear ring is engaged with the bevel gear at the output end of the electric drive bevel gear 5, after the electric drive bevel gear 5 is energized, the motor drives the bevel gear to rotate. According to the gear meshing principle, the gear turntable 4 is driven to rotate in the opening of the arc bracket 3, thereby closing the connection with the arc bracket 3 to increase the protection effect. As the electric drive slide plate 8 is energized, the slider on the slide rail of the electric drive slide plate 8 rotates, thereby driving the horizontal position of the steering paint spray gun 9 to achieve full spraying of the helmet surface. Among them, the paint is transported to the steering paint spray gun 9 through the external paint supply system through the telescopic tube 11, the connecting tube 10 and the hose. When the paint spray gun is working, the paint is sprayed onto the surface of the helmet. The telescopic tube 11 can adaptively adjust the length during the process of the hydraulic lifting column 7 driving the electric drive slide plate 8 to rise and fall, ensuring smooth paint supply.

[0055] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
