Description

Technical Field

[0001] The present invention relates to the technical field of coating equipment, and more specifically, to an electrostatic spray coating equipment. Background Art

[0002] Electrostatic spraying is a new type of painting method designed based on the basic characteristics that like charges repel each other and opposite charges attract each other. It uses the effect of a DC high-voltage electric field to atomize the paint mist sprayed from the spray gun into a finer atomizer, and at the same time makes the paint mist charged, which is deposited on the surface of the workpiece with opposite charges through electrostatic attraction to form a uniform paint film, thus achieving the purpose of painting. It is an efficient painting method that combines mechanical atomization with electrostatic attraction and repulsion.

[0003] A Chinese patent with authorization publication number CN220091746U discloses an electrostatic spray coating device, in which the nozzle of the electrostatic spray gun is tilted upward by a rotating block, so the spray liquid sprayed from the electrostatic spray gun will spray to the bottom surface of the workpiece. When the electrostatic spray gun moves above the workpiece, the driving gear will drive the rotating shaft to rotate clockwise, and the nozzle of the electrostatic spray gun can be tilted downward by the rotating block, so the spray liquid sprayed from the electrostatic spray gun will spray to the top surface of the workpiece, thereby achieving spray treatment on all surfaces of the workpiece, effectively improving the working efficiency of the device.

[0004] Although this kind of electrostatic spray coating equipment can realize spraying treatment on all surfaces of the workpiece and effectively improve the working efficiency of the device, in the current spraying operation, the fixing effect of the fixing equipment used for the workpiece to be sprayed is not ideal, especially during the processing process, if the workpiece shakes at all, it will significantly affect the spraying quality, resulting in uneven coating or defects. Especially for those workpieces with softer materials and easy to deform, the traditional external clamping fixing method is particularly unsuitable, because this fixing method may bring additional pressure to the material, causing unnecessary deformation, thereby interfering with the normal spraying process and even damaging the workpiece itself.

[0032] The external support fixing mechanism also includes a support member 15 fixedly installed on the lower side of the outer surface of the special-shaped threaded sleeve 13, a slide rail 16 is provided on the lower end surface of the fixed plate 9, a transmission rod 17 is slidably connected inside the slide rail 16, a slot 18 is provided at the end of the transmission rod 17, a connecting rod 19 is rotatably connected between the slot 18 and the support member 15, a support member 20 is fixedly installed on the other end of the transmission rod 17, a slot 21 is provided on the outer surface of the fixed plate 210, a push rod 22 is rotatably connected between the slot 21 and the support member 20, a support plate 23 is fixedly installed on the outer surface of the push rod 22, and the support member 15, the slot 18, the support member 20, the slot 21, the slide rail 16, the connecting rod 19, the push rod 22 and the support plate 23 are all fixedly installed in multiple groups and are dispersedly arranged in a ring shape.

[0033] The outer shell 7 is placed inside the box body 1 and sleeved on the outer surface of the equipment, and then the motor 11 is started so that the output shaft of the motor 11 drives the threaded rod 12 to rotate. The threaded rod 12 is spirally connected to the special-shaped threaded sleeve 13, so the special-shaped threaded sleeve 13 will carry multiple groups of support members 15 to rise. The support members 15 and the grooves 18 on the transmission rod 17 are rotationally connected through the connecting rod 19. Therefore, when the special-shaped threaded sleeve 13 carries multiple groups of support members 15 to rise, it will drive the transmission rod 17 to slide outward inside the slide rail 16.

[0034] The transmission rod 17 slides outward inside the slide rail 16 to drive the support member 20 to be pushed outward, and a push rod 22 is rotatably connected between the support member 20 and the slot 21 opened on the fixed plate 10, thereby driving the push rod 22 to tilt around the slot 21, thereby causing the support plate 23 on the push rod 22 to support the inside of the conically arranged outer shell 7, so that the outer shell 7 is supported and fixed.

[0035] In the current spraying operation, the fixing effect of the fixing equipment used for the workpiece to be sprayed is not ideal, especially during the processing, if the workpiece shakes at all, it will significantly affect the spraying quality, resulting in uneven coating or defects, especially for those workpieces with softer materials and easy to deform. The traditional external clamping fixing method is particularly unsuitable, because this fixing method may bring additional pressure to the material, causing unnecessary deformation, thereby interfering with the normal spraying process and even damaging the workpiece itself. Therefore, this scheme is particularly suitable for processing the outer shell 7 made of special materials by setting an external support fixing mechanism. By cleverly using the support plate 23 to support and fix the inside from the outside, the problem of the traditional external clamping fixing method easily causing the outer shell 7 to deform is effectively solved, and it can ensure that the original shape and structural integrity of the outer shell 7 are maintained during installation or maintenance.

[0036] The expansion fixing mechanism includes an arc rod 1 24 fixedly installed on the front end faces of multiple groups of transmission rods 17, and an arc rod 2 25 fixedly installed on the rear end faces of multiple groups of transmission rods 17. The outer surfaces of adjacent arc rods 1 24 and arc rods 25 are sleeved with arc sleeves 26, and the outer surface of the arc sleeve 26 is fixedly installed with a support member 3 27. The top rod 22 is rotatably connected between the support member 3 27 and the slot 21.

[0037] The transmission rod 17 slides outward inside the slide rail 16 to drive the support member 20 to be pushed outward, and a push rod 22 is rotatably connected between the support member 20 and the slot 21 opened on the fixed plate 10, thereby driving the push rod 22 to tilt around the slot 21, thereby causing the support plate 23 on the push rod 22 to support the inside of the conically arranged outer shell 7, so that the outer shell 7 is supported and fixed.

[0038] Secondly, the following method can also be adopted: the front end face and the rear end face of the transmission rod 17 are respectively fixedly installed with an arc rod 1 24 and an arc rod 2 25, and the transmission rod 17, the arc rod 1 24 and the arc rod 2 25 are arranged in a ring-shaped dispersion in multiple groups, and an arc sleeve 26 is sleeved between the arc rod 2 25 on the transmission rod 17 and the arc rod 1 24 on the adjacent transmission rod 17. With the external support of the transmission rod 17, the arc sleeve 26 is synchronously displaced outward, and a gradually expanding ring is formed between the multiple groups of arc sleeves 26, the arc rod 1 24 and the arc rod 2 25, and finally it is tightly attached to the inner wall of the outer shell 7, and the outer surface of the arc sleeve 26 is fixedly installed with a support member 3 27, and a push rod 22 is also rotatably connected between the support member 3 27 and the slot 2 21, and the support plate 23 on the push rod 22 can also be tightly attached to the outer shell 7, so as to support and fix the outer shell 7 internally.

[0039] The adsorption and fixing mechanism includes a threaded rod 28 fixedly installed at the end of the upper output shaft of the motor 11, the end of the threaded rod 28 is spirally connected with a special-shaped threaded sleeve 30, the upper end of the fixed plate 10 is fixedly installed with a limiting sleeve 29, the limiting sleeve 29 is sleeved on the outer side of the threaded rod 28, the special-shaped threaded sleeve 30 is slidably connected with the limiting sleeve 29, the upper end of the limiting sleeve 29 is fixedly installed with a supporting shell 31, and the upper end of the special-shaped threaded sleeve 30 is fixedly installed with a suction cup 32.

[0040] The output shaft at the upper end of the motor 11 will drive the threaded rod 28 to rotate. The upper end of the threaded rod 28 is spirally connected to the special-shaped threaded sleeve 230, so the special-shaped threaded sleeve 230 will descend. When the outer shell 7 is mounted on the outer surface of the device, the suction cup 32 on the upper side of the device will be tightly attached to the outer shell 7, and as the special-shaped threaded sleeve 230 descends, the center of the suction cup 32 will be pulled, thereby forming a vacuum area between the suction cup 32 and the outer shell 7, and the outer shell 7 is adsorbed and fixed by the principle of vacuum adsorption.

[0041] The lifting and fixing mechanism includes a lifting plate 33 fixedly installed at the lower end of the special-shaped threaded sleeve 13, the outer surface of the lifting plate 33 is inclined, the interior of the special-shaped threaded sleeve 13 is provided with an inner cavity 39, the interior of the lifting plate 33 is provided with a transmission cavity 34, the transmission cavity 34 and the inner cavity 39 are communicated with each other, the interior of the transmission cavity 34 is slidably connected with a slide rod 35, the end of the slide rod 35 is fixedly installed with a connector 1 36, the end of the connector 1 36 is rotatably connected with a connector 2 38, and the end of the connector 2 38 is fixedly installed with an arc-shaped top plate 37.

[0042] When the special-shaped threaded sleeve 13 rises, the lifting plate 33 will be carried up synchronously. At the same time, the air inside the inner cavity 39 inside the special-shaped threaded sleeve 30 will gradually enter the interior of the transmission cavity 34 due to the gradual squeezing of the threaded rod 12, and the sliding rod 35 inside the transmission cavity 34 will be ejected, so that the sliding rod 35 drives the connecting piece 1 36 to move outward, and the connecting piece 1 36 is rotatably connected with the connecting piece 2 38 on the arc-shaped top plate 37, so that the arc-shaped top plate 37 is finally tightly attached to the inner wall of the outer shell 7, so as to perform internal support and fixation. After the fixation is completed, the rear shell drives the turntable 6 to drive the outer shell 7 in the fixed state to rotate, and cooperates with the nozzle 5 and the telescopic rod 4 to perform a full-scale spraying operation on the outer surface of the outer shell 7.

[0043] Directions:

[0044] The housing 7 is placed inside the box body 1 and sleeved on the outer surface of the device, and then the motor 11 is started, so that the output shaft of the motor 11 drives the threaded rod 12 to rotate, and the threaded rod 12 is connected with the special-shaped threaded sleeve 13 by spiral transmission, so the special-shaped threaded sleeve 13 will carry multiple groups of support members 15 to rise, and the support members 15 and the notches 18 on the transmission rod 17 are rotatably connected through the connecting rod 19, so when the special-shaped threaded sleeve 13 carries multiple groups of support members 15 to rise, it will drive the transmission rod 17 to slide outward inside the slide rail 16;

[0045] The transmission rod 17 slides outward inside the slide rail 16 to drive the second support member 20 to be pushed outward, and the second support member 20 is rotatably connected with the second notch 21 provided on the second fixing plate 10, so that the push rod 22 is driven to tilt around the second notch 21, thereby making the support plate 23 on the push rod 22 and the inside of the conical shell 7 to support the shell 7 externally, so that the shell 7 is supported and fixed externally;

[0046] Secondly, the following method can also be adopted: the front end face and the rear end face of the transmission rod 17 are respectively fixedly installed with an arc rod 1 24 and an arc rod 2 25, and the transmission rod 17, the arc rod 1 24 and the arc rod 2 25 are arranged in a ring-shaped dispersion in multiple groups, and an arc sleeve 26 is sleeved between the arc rod 2 25 on the transmission rod 17 and the arc rod 1 24 on the adjacent transmission rod 17. With the external support of the transmission rod 17, the arc sleeve 26 is synchronously displaced outward, and a gradually expanding ring is formed between the multiple groups of arc sleeves 26, the arc rod 1 24 and the arc rod 2 25, and finally it is tightly attached to the inner wall of the outer shell 7, and the outer surface of the arc sleeve 26 is fixedly installed with a support member 3 27, and a push rod 22 is also rotatably connected between the support member 3 27 and the slot 2 21, and the support plate 23 on the push rod 22 can also be tightly attached to the outer shell 7, so as to support and fix the outer shell 7 internally.

[0047] The output shaft at the upper end of the motor 11 drives the threaded rod 28 to rotate, and the upper end of the threaded rod 28 is spirally connected to the special-shaped threaded sleeve 20, so the special-shaped threaded sleeve 20 will descend. When the shell 7 is sleeved on the outer surface of the device, the suction cup 32 on the upper side of the device will be tightly attached to the shell 7, and as the special-shaped threaded sleeve 20 descends, the center of the suction cup 32 will be pulled, so that a vacuum area is formed between the suction cup 32 and the shell 7, and the shell 7 is adsorbed and fixed by the principle of vacuum adsorption;

[0048] When the special-shaped threaded sleeve 13 rises, the lifting plate 33 will be carried up synchronously. At the same time, the air inside the inner cavity 39 inside the special-shaped threaded sleeve 30 will gradually enter the interior of the transmission cavity 34 due to the gradual squeezing of the threaded rod 12, and the sliding rod 35 inside the transmission cavity 34 will be ejected, so that the sliding rod 35 drives the connecting piece 1 36 to move outward, and the connecting piece 1 36 is rotatably connected with the connecting piece 2 38 on the arc-shaped top plate 37, so that the arc-shaped top plate 37 is finally tightly attached to the inner wall of the outer shell 7, so as to perform internal support and fixation. After the fixation is completed, the rear shell drives the turntable 6 to drive the outer shell 7 in the fixed state to rotate, and cooperates with the nozzle 5 and the telescopic rod 4 to perform a full-scale spraying operation on the outer surface of the outer shell 7.
