Description

Technical Field

[0001] The invention relates to the technical field of material processing, and in particular to large-scale steel plate automatic shot blasting, painting and drying integrated equipment. Background Art

[0002] Large steel plates are mainly used in larger structural workpieces. Due to their large size and high weight, they are inconvenient to transport and assemble. At the same time, they are prone to rust during actual use, which affects product quality. Traditional shot blasting equipment usually uses multiple sets of equipment. However, when facing steel plates with larger areas, they are constrained by the implementation principle of the swing wheel shot blasting of the shot blasting machine. The shot blasting effect tends to weaken in areas that are relatively deviated from the shot blasting direction. Large shot blasting equipment should be avoided from moving as much as possible during operation, resulting in uneven implementation range. At the same time, the steel plates need to be quickly repainted for anti-oxidation treatment after treatment. If they are dried on site, the paint in the paint spray nozzle may harden and affect subsequent operations. Summary of the invention

[0017] In one embodiment, a solution is provided in the liquid receiving bowl.

[0018] The beneficial effects of the present invention are as follows: the present invention is a large-scale steel plate automatic shot blasting and paint drying integrated equipment that effectively avoids repeated handling, maintains shot blasting quality, and can also perform paint spraying and drying. The specific implementation method is as follows:

[0019] The operator first places the treated steel plate in the gap of the groove wheel, adjusts the height of the lifting adjustment rod, so that the paint spraying port on the paint spraying mechanism meets the requirements of the treated steel plate for painting, and then rotates the threaded rotating rod to drive the connecting long rod to adjust the height of the impurity removal shot blasting machine. After adapting to the height of the treated steel plate, the transport motor is started to drive the groove wheel to rotate, and at the same time, the treated steel plate is pushed through the door curtain to move into the isolation workshop until the treated steel plate passes through the shot blasting mechanism. Then, the impurity removal shot blasting machine is started to shot blast one side of the treated steel plate, and the swing motor is started at the same time. The swing motor drives the rotating disk to rotate, and at the same time drives the rolling ball on the extrusion nail to pass through the bevel on the inclined step protrusion. The inclined step protrusion squeezes the rolling ball and compresses the rolling spring to squeeze the closed part on the extrusion nail to clamp the treated steel plate. The rotating disk continues to rotate, and the clamped extrusion nail drives the treated steel plate to move in a curve. Since the positions of the inclined step protrusions on the adjacent driving disks are symmetrically arranged, they will change differently according to the fan-shaped curvature of the inclined step protrusions:

[0020] If the fan-shaped arc of the oblique step protrusion is equal to 90°, when the rolling ball on the squeezing pin disengages from the oblique step protrusion to cancel the squeezing pin's clamping of the processed steel plate, the squeezing pins of the adjacent driving disks clamp at the same time, driving the processed steel plate to generate a wave-like motion trajectory;

[0021] If the fan-shaped arc of the inclined step protrusion is less than 90°, when the rolling ball on the squeezing pin disengages from the inclined step protrusion to cancel the squeezing pin's clamping of the processed steel plate, the processed steel plate falls onto the groove wheel, and the squeezing pins of the adjacent driving disk are clamped, and the squeezing groove wheel presses the buckle block on the support disk to move along the guide of the support column, and then the squeezing pin continues to disengage from the clamping of the processed steel plate, and the support spring returns to its position, so that the processed steel plate returns to its initial clamping position;

[0022] The above movements can be achieved by slowly moving the processed steel plate to follow a wave-like motion trajectory when the impurity removal shot blasting machine is performing shot blasting, so that the area with denser shot blasting overlaps with the looser area, further increasing the shot blasting quality and avoiding the quality problem of uneven striped shot blasting. At the same time, during the above shot blasting process, the dust removal equipment is started for dust removal.

[0023] After completing the single-side shot blasting, the treated steel plate needs to be sprayed with paint for protection. Since the paint is relatively fragile before it dries after spraying, it needs to be moved without contact. All swing motors are started to rotate to separate the extrusion pins from the position of the inclined step protrusions, so that all the extrusion pins are separated from the extrusion of the treated steel plate. Then, the sliding block is slid to slightly tilt the treated steel plate. After that, the first rotating rod and the second rotating rod are flipped, and the paint spraying mechanism and the impurity removal shot blasting machine on both sides are lifted and separated from both sides of the treated steel plate. Then, the transmission motor is started to rotate and the paint spraying mechanism is moved to the area where the shot blasting process is completed. , then flip the first rotating rod and the second rotating rod to interchange the positions of the paint spraying mechanisms and impurity removal shot blasting machines on both sides, and then you can prepare for painting. Start the transport motor to drive the treated steel plate on the groove wheel to move through the paint spraying port on the paint spraying box to complete the painting. After completion, flip the first rotating rod and the second rotating rod to lift and fix the paint spraying mechanisms and impurity removal shot blasting machines on both sides, and then start the drying equipment to dry the painted surface to complete the single-sided treatment of the steel plate; repeat the above-mentioned shot blasting and paint drying steps in reverse to achieve complete treatment of the treated steel plate.

[0024] Since the paint spraying mechanism is in the same area when the drying equipment is drying, the paint spraying port on the paint spraying tube needs to be protected to prevent the paint from solidifying. When the second rotating rod flips, the liquid receiving bowl is relatively still due to gravity. At the same time, the flipping of the paint spraying tube drives the rotating support rod on the connecting plate to flip, and further drives the rotating gear on the rotating support rod to rotate and engage the lifting rack, causing the rotating support rod to move in the lifting slot, so that the paint spraying port rotates and extends into the liquid receiving bowl. The solution in the liquid receiving bowl protects the paint in the paint spraying port to prevent solidification.

[0025] The equipment has a simple structure. It avoids the uneven quality problem of shot blasting in the form of stripes during the shot blasting process by processing the movement of the processed steel plates. At the same time, it effectively arranges the drying equipment and the painting mechanism in the same area, thereby reducing the use area of ​​the equipment. It can process large-mass and large-area processed steel plates without repeated handling work. It has good stability and usability, which is beneficial to the promotion and use of the equipment.

[0055] Working principle of the present invention:

[0056] The operator first places the treated steel plate 14 in the gap of the groove wheel 235, adjusts the height of the lifting adjustment rod 511, so that the paint port 521 on the paint spraying mechanism 5 can meet the requirements of the treated steel plate 14 for painting, and then rotates the threaded rotating rod 45 to drive the connecting long rod 451 to adjust the height of the impurity removal shot blasting machine 46. After the height of the treated steel plate 14 is adapted, the transport motor 236 is started to drive the groove wheel 235 to rotate, and at the same time, the treated steel plate 14 is pushed through the door curtain 11 to move into the isolation workshop 1. After the treated steel plate 14 passes through the shot blasting mechanism 4, the impurity removal shot blasting machine 46 is started to spray the treated steel plate 14. One side of the plate 14 is shot blasted, and the swing motor 32 is started at the same time. The swing motor 32 drives the rotating disk 36 to rotate, and at the same time drives the rolling ball 371 on the squeezing nail 37 to pass through the bevel on the inclined step protrusion 35. The inclined step protrusion 35 squeezes the rolling ball 371 and compresses the rolling spring 372 to squeeze the closed part on the squeezing nail 37 to clamp the processed steel plate 14. The rotating disk 36 continues to rotate, and the clamped squeezing nail 37 drives the processed steel plate 14 to move in a curve. Since the inclined step protrusions 35 on the adjacent driving disks 34 are symmetrically arranged, different changes will occur according to the fan-shaped curvature of the inclined step protrusion 35:

[0057] If the fan-shaped arc of the oblique step protrusion 35 is equal to 90°, when the rolling ball 371 on the squeezing pin 37 disengages from the oblique step protrusion 35 to cancel the squeezing pin 37 clamping the processing steel plate 14, the squeezing pins 37 of the adjacent driving disk 34 clamp at the same time, driving the processing steel plate 14 to generate a wave motion trajectory;

[0058] If the fan-shaped arc of the inclined step protrusion 35 is less than 90°, when the rolling ball 371 on the squeezing pin 37 disengages from the inclined step protrusion 35 to cancel the squeezing pin 37 clamping the processing steel plate 14, after the processing steel plate 14 falls onto the groove wheel 235, the squeezing pin 37 of the adjacent driving disk 34 clamps it, and the squeezing groove wheel 235 presses the buckle block 234 on the support disk 231 to squeeze the supporting spring 233 to move along the guide of the support column 232, and then the squeezing pin 37 continues to disengage from the clamping of the processing steel plate 14, and the supporting spring 233 returns to its position, so that the processing steel plate 14 returns to its initial clamping position;

[0059] The above movements can be achieved by slowly moving the processed steel plate 14 to follow a wave-like motion trajectory when the impurity removal shot blasting machine 46 is performing shot blasting, so that the area with denser shot blasting overlaps with the looser area, further increasing the shot blasting quality and avoiding the quality problem of uneven striped shot blasting. At the same time, during the above shot blasting process, the dust removal equipment 13 is started to remove dust.

[0060] After completing the single-sided shot blasting, the treated steel plate 14 needs to be sprayed with paint for protection. Since the paint is relatively fragile before it dries after spraying, it needs to be moved without contact. All the swing motors 32 are started to rotate to disengage the squeezing pins 37 from the position of the inclined step protrusions 35, so that all the squeezing pins 37 are separated from the squeezing of the treated steel plate 14. Then, the sliding block 23 is slid to slightly tilt the treated steel plate 14. After that, the first rotating rod 43 and the second rotating rod 431 are flipped over, and the paint spraying mechanism 5 and the impurity removal shot blasting machine 46 on both sides are lifted and separated from the two sides of the treated steel plate 14. Then, the transmission motor 41 is started to rotate, and the paint spraying mechanism 5 is moved to the area where the shot blasting process is completed. After that, flip the first rotating rod 43 and the second rotating rod 431 to interchange the positions of the paint spraying mechanisms 5 and the impurity removal shot blasting machines 46 on both sides, and then prepare for painting. Start the transport motor 236 to drive the treated steel plate 14 on the groove wheel 235 to move through the paint spraying port 521 on the paint spraying box 51, and then the painting is completed. After completion, flip the first rotating rod 43 and the second rotating rod 431 to lift and fix the paint spraying mechanisms 5 and the impurity removal shot blasting machines 46 on both sides, and then start the drying equipment 12 to dry the painted surface, and the single-sided treatment of the steel plate can be completed; repeat the above-mentioned shot blasting and paint drying steps in reverse to achieve complete treatment of the treated steel plate 14.

[0061] Since the paint spraying mechanism 5 is in the same area when the drying equipment 12 is drying, the paint spraying port 521 on the paint spraying tube 52 needs to be protected to prevent the paint from solidifying. When the second rotating rod 431 flips, the liquid receiving bowl 53 is relatively still due to gravity. At the same time, the flipping of the paint spraying tube 52 drives the rotating support rod 541 on the connecting plate 54 to flip, and further drives the rotating gear 542 on the rotating support rod 541 to rotate and engage the lifting rack 543, causing the rotating support rod 541 to move in the lifting slot 532, so that the paint spraying port 521 rotates and extends into the liquid receiving bowl 53. The solution in the liquid receiving bowl 53 protects the paint in the paint spraying port 521 to prevent solidification.
