Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 - 10 , the present invention provides a technical solution: an adaptive adjustment type multi-directional precision paint spraying machine for helmet production, including a base 1, a hydraulic column 2, an arc bracket 3, a gear turntable 4, an electric drive bevel gear 5, a positioning frame one 6, a first hydraulic lifting column 7, an electric drive slide rail disc 8, a steering paint spray gun 9, a connecting pipe 10, a telescopic pipe 11, a positioning frame two 12, a ball screw 13, a limit sliding frame 14, a second hydraulic lifting column 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-shaped frame structure. Two hydraulic columns 2 are symmetrically arranged at the upper end of the base 1, and an arc bracket 3 is fixedly installed at the output end of the hydraulic column 2. There is a steering paint spray gun 9 below the arc bracket 3, and the steering paint spray gun 9 is the main spraying device for helmet spraying;

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

[0046] As shown in the attached drawings of 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 expands and contracts, driving the arc-shaped bracket 3 to rise or fall, realizing the adjustment of the overall painting height, ensuring that a proper vertical distance is maintained between the steering paint spray gun 9 and 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 inside the opening of the arc-shaped bracket 3 is meshed 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 inside the opening of the arc-shaped bracket 3. As Figures 4 - 5 shown, the rotation of the gear turntable 4 drives the connected components to rotate, realizing the angle adjustment of the steering paint spray gun 9 in the horizontal direction, enabling the steering paint spray gun 9 to paint the surface of the helmet at a proper angle. The steering paint spray gun 9 is installed on an electric lifting bracket, which uses a motor to drive a lead screw or chain drive 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 and completing the reciprocating spraying work. When the gear turntable 4 rotates, its arc-shaped pieces are in contact with the inner wall of the opening of the arc-shaped bracket 3, and a sealing strip or protective cover structure is provided between the two. As the gear turntable 4 rotates and gradually closes, a sealed space is formed, effectively preventing paint from splashing onto other parts of the equipment;

[0047] The spraying of the helmet is carried out by starting the electric drive slide rail disc 8. The slider on the slide rail of the electric drive slide rail disc 8 rotates driven by the motor, driving the rotating rod bracket and the steering paint spray gun 9 to move in the horizontal direction. According to the shape of the helmet and the requirements of the painting process, the operator adjusts the reciprocating movement of the slider of the electric drive slide rail disc 8 through the control system, so that the steering paint spray gun 9 comprehensively and evenly sprays the surface of the helmet in the horizontal direction. The paint for spraying is supplied by an external paint supply system and is transported to the steering paint spray gun 9 through the telescopic pipe 11, the connecting pipe 10 and the hose. When the steering paint spray gun 9 is working, the paint is evenly sprayed onto the surface of the helmet. During the process of the hydraulic lifting column 1 driving the electric drive slide rail disc 8 to lift and lower, the telescopic pipe 11 adaptively adjusts its length to ensure the smooth supply of paint and ensure the continuity and stability of the painting process;

[0048] When the painting of the helmet is completed, close the paint supply valve of the steering paint spray gun 9 to stop the paint transportation. At the same time, turn off the motors of components such as the electric drive bevel gear 5 and the electric drive slide rail disc 8 to stop the painting operation of the equipment. During actual use, the operator should regularly clean the parts that are prone to paint residue, such as the steering paint spray gun 9, the connecting pipe 10, the telescopic pipe 11, and the arc-shaped bracket 3, to keep the equipment clean;

[0049] The electric drive slide rail disc 8 and the steering paint spray gun 9 are arranged parallel to each other vertically, 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 pipe 11. There is a helmet support assembly below the steering paint spray gun 9, and the helmet support assembly includes a limit slide frame 14, a hydraulic lifting column 2 15, a ventilation frame 16, a double-layer telescopic sleeve 17 and a spring lifting sleeve 18. Among them, the limit slide frame 14 is slidably connected in the base 1. The upper end surface of the base 1 is provided with a strip-shaped slide rail, and positioning frames 2 12 are respectively installed at both ends of the strip-shaped slide rail 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 rail disc 8, and the connecting pipe 10 and the telescopic pipe 11 are vertically arranged on the side wall of the hydraulic lifting column 1. The ball screw 13 passes through the limit slide frame 14, and the hydraulic lifting column 2 15 is snap-connected to the upper end of the limit slide frame 14. The output end of the hydraulic lifting column 2 15 is provided with a ventilation frame 16. A through slide bar is provided between the two limit slide frames 14, and the limit slide frame 14 and the hydraulic lifting column 2 15 are arranged perpendicular to each other. The top of the ventilation frame 16 is snap-connected to the spring lifting sleeve 18, and a cross-shaped pipe is arranged in the ventilation frame 16, and a double-layer telescopic sleeve 17 is snap-connected in the pipe of the ventilation frame 16. The double-layer telescopic sleeve 17 is a sleeve rod structure with two-stage sliding connection, and a corrugated pipe is arranged between the two sleeve rods of the double-layer telescopic sleeve 17, and the corrugated pipe of the double-layer telescopic sleeve 17 is communicated with the pipe of the ventilation frame 16. The spring lifting sleeve 18 is a slide rod with two-stage sliding connection, and a spring structure is arranged between the slide rod structures of the spring lifting sleeve 18;

[0050] Combined with the accompanying drawings of the specification Figures 1 - 10 As shown, place the helmet to be painted above the spring lifting sleeve 18. At this time, the gravity of the helmet will cause the spring lifting sleeve 18 to descend, compressing the spring. During the descent of the spring lifting sleeve 18, the gas in the bellows inside it is extruded and filled into the ventilation frame 16. Subsequently, 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 silica gel on the outer rod surface is in full contact with the inner layer of the helmet, initially achieving the positioning and fixation of the helmet. The silica gel on the outer wall surfaces of the spring lifting sleeve 18 and the double-layer telescopic sleeve 17 is used to increase the contact friction with the helmet to prevent the helmet from being impacted and toppled by the sprayed paint when spraying. Start the motor to drive the rotation of the ball screw 13 in the positioning frame two 12. Since the ball screw 13 penetrates the limit slide 14, according to the principle of screw drive, the limit slide 14 will perform a linear motion on the strip-shaped 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, precisely adjusting the position of the limit slide 14, thereby realizing the position adjustment of the helmet in the horizontal direction and ensuring that the helmet is in a suitable painting position.

[0051] According to the height requirement of the helmet, the operator issues an instruction through the control system to control the hydraulic system of the hydraulic lifting column two 15. The output end of the hydraulic lifting column two 15 expands and contracts according to the instruction, driving the ventilation frame 16 to drive the helmet to rise or fall as a whole, thereby adjusting the vertical height of the helmet and making the helmet at a suitable painting height.

[0052] Working principle: When using this multi-directional precise painting machine for adaptive adjustment type helmet production, first place the helmet above the spring lifting sleeve 18. The spring lifting sleeve 18 descends under gravity, causing the spring of the spring lifting sleeve 18 to descend, and the gas in the bellows of the spring lifting sleeve 18 is filled into the ventilation frame 16. Subsequently, the gas is filled into the bellows of the double-layer telescopic sleeve 17, and the double-layer sleeves of the double-layer telescopic sleeve 17 expand, causing the silica gel to be provided on the outer rod surface of the double-layer telescopic sleeve 17 to be in full contact with the inner layer of the helmet. The ball screw 13 in the positioning frame two 12 is driven by the motor to rotate. Since the ball screw 13 penetrates the limit slide 14, according to the principle of screw drive, the limit slide 14 will perform a linear motion on the strip-shaped slide rail, thereby realizing the position adjustment of the helmet in the horizontal direction to meet the fixing requirements of helmets of different sizes and the requirements of the painting position;

[0053] According to the height requirement of the helmet, control the expansion and contraction of the output end of the hydraulic lifting column two 15 through the hydraulic system, driving the ventilation frame 16 to rise or fall, and making the helmet at a suitable painting height;

[0054] As the hydraulic column 2 controls the telescopic movement of the output end through the hydraulic system, it drives the arc-shaped bracket 3 to rise or fall, adjusting the overall painting height. Due to the gear turntable 4 within the opening of the arc-shaped bracket 3, the annular gear ring thereof meshes with the bevel gear at the output end of the electric drive bevel gear 5. After the electric drive bevel gear 5 is powered on, the motor drives the bevel gear to rotate. According to the gear meshing principle, it drives the gear turntable 4 to rotate within the opening of the arc-shaped bracket 3, thereby closing the connection with the arc-shaped bracket 3 to enhance the protective effect. After the electric drive slide rail disc 8 is powered on, the slider on the slide rail of the electric drive slide rail disc 8 rotates, thereby driving the adjustment of the horizontal orientation of the rotary spray gun 9 to achieve full spraying on the surface of the helmet. Among them, the paint is supplied through an external paint supply system and is transported to the rotary spray gun 9 through the telescopic pipe 11, the connecting pipe 10, and the hose. When the spray gun is working, the paint is sprayed onto the surface of the helmet. The telescopic pipe 11 can adaptively adjust its length during the lifting and lowering of the electric drive slide rail disc 8 driven by the hydraulic lifting column 1 to ensure the smooth supply of paint.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
