Description

Technical Field

[0001] The invention relates to the technical field of guardrail painting, and in particular to fully automatic painting processing equipment for stainless steel guardrails. Background Art

[0002] Stainless steel guardrails, also known as stainless steel composite pipe guardrails, are mainly used in bridge guardrails, road guardrails, factory fences, courtyard fences, etc. They have the advantages of stainless steel pipes being beautiful and rust-free and carbon steel pipes being hard and low-priced. In the actual use of stainless steel guardrails, scratches caused by transportation and installation will damage the protective layer on the surface of the stainless steel, which not only affects the appearance, but also causes internal rust, thus affecting the lifespan. Therefore, it is necessary to spray paint on the surface of the stainless steel guardrails to further protect the stainless steel surface. The guardrail spray painting device in the prior art can only spray paint on a single guardrail, and cannot spray paint on the entire guardrail, resulting in a low processing rate, and the spray painting requires manual operation, which is very inconvenient.

[0005] Furthermore, the fence taking mechanism includes a rotating rod motor fixedly mounted on a motor frame, a movable guide frame fixedly mounted on the motor frame, an outer rotating rod fixedly mounted on the motor shaft of the rotating rod motor, an inner sliding rod slidably mounted on the outer rotating rod, a rotating column block rotatably mounted on the inner sliding rod, a lifting slider rotatably mounted on the rotating column block, the lifting slider and the movable guide frame are slidably mounted, a concave track is provided on the motor frame, the rotating column block slides in the concave track, and a steering mechanism is provided on the lifting slider.

[0006] Furthermore, the steering mechanism includes a fence frame rotatably mounted on a lifting slide block, a rotating gear is fixedly mounted on the fence frame, a fixed rack is fixedly mounted on the movable guide frame, and a slope support block is fixedly mounted on the fence frame.

[0007] When the rotating column block slides to the right along the concave track, the lifting slider drives the slope support block to rise, and the stainless steel guardrail is lifted up by the lifting slider after the slope support block is lifted up. The support block detaches from the blocking plate, and the stainless steel guardrail passes over the blocking plate and enters the groove of the slope support block. The stainless steel guardrail behind slides to the blocking plate through the placement plate in turn and continues to be blocked by the blocking plate. Then the rotating rod motor reverses, and drives the rotating column block to slide to the left through the outer rotating rod and the inner sliding rod.

[0012] After the clamp carries the stainless steel guardrail for painting in the paint spraying room, the clamp carries the stainless steel guardrail into the drying box and is dried by the burner. When the clamp carries the stainless steel guardrail to the top of the lifting slope, the lifting slider rises, which just lifts the lifting rod, thereby driving the lifting slope to rise, and lifts the stainless steel guardrail through the lifting end, so that the stainless steel guardrail is separated from the clamp, and then under the action of the concave end, the stainless steel guardrail tilts and falls on the slope of the lifting slope. At this time, the stainless steel guardrail on the lifting slope can be removed manually.

[0014] When the rotating clamping frame and the clamping claw bring the stainless steel guardrail into the paint spraying room, the paint in the paint spray barrel is pumped into the lower spray pipe and the upper spray pipe through the pump, and then enters the upper spray gun and the lower spray gun, and the stainless steel guardrail is sprayed with paint by the upper spray gun and the lower spray gun. At the same time, the rotation of the paint spraying motor drives the lifting gear to rotate, thereby driving the upper rack to descend and the lower rack to rise, so that the upper spray gun and the lower spray gun can spray paint on the entire surface of the stainless steel guardrail. The excess paint flows into the return pipe through the slope at the bottom of the paint spraying room, and returns to the paint spray barrel through the one-way valve, so as to realize the recycling of the residual paint.

[0041] When the rotating clamping frame 207 and the clamping claw 208 bring the stainless steel guardrail 4 into the paint spraying room 301, the paint in the paint spray barrel 302 is pumped into the lower spray pipe 304 and the upper spray pipe 305 through the pump 303, and then enters the upper spray gun 309 and the lower spray gun 306, and the stainless steel guardrail 4 is sprayed with paint by the upper spray gun 309 and the lower spray gun 306. At the same time, the paint spraying motor 310 rotates to drive the lifting gear 311 to rotate, thereby driving the upper rack 308 to descend, and the lower rack 307 to rise, so that the upper spray gun 309 and the lower spray gun 306 can spray paint on the entire surface of the stainless steel guardrail 4, and the excess paint flows into the return pipe 312 through the slope at the bottom of the paint spraying room 301, and returns to the paint spray barrel 302 through the one-way valve, so as to realize the recycling of the residual paint.

[0042] The working principle of the fully automatic painting processing equipment for stainless steel guardrails disclosed in the present invention is as follows: a plurality of stainless steel guardrails 4 are placed on a placement plate 102, the stainless steel guardrails 4 are blocked by a blocking plate 103, the rotating rod motor 114 rotates to drive the outer rotating rod 105 to rotate, thereby driving the inner sliding rod 106 to rotate, the inner sliding rod 106 slides relative to the outer rotating rod 105, thereby driving the rotating column block 107 to slide along the concave track 1041, when the rotating column block 107 is located at both ends of the concave track 1041, the lifting slide block 108 is lifted to the highest point along the movable guide frame 112, and along with the inner sliding rod 10 6 With the rotating column block 107 moving to the left, the rotating column block 107 first descends, thereby driving the lifting slide block 108 to descend. After the lifting slide block 108 descends, it slides along the lower surface of the movable guide frame 112. When the rotating gear 110 contacts the fixed rack 111, under the action of the fixed rack 111, the rotating gear 110 and the fence frame 109 rotate 180 degrees. During the process of the rotating column block 107 sliding to the right along the concave track 1041, after the rotating column block 107 reaches the right end of the concave track 1041, the lifting slide block 108 drives the slope support block 113 to rise. The slope of the block 113 lifts up the stainless steel guardrail 4, and the slope support block 113 is separated from the blocking plate 103. The stainless steel guardrail 4 passes over the blocking plate 103 and enters the groove of the slope support block 113. The stainless steel guardrail 4 behind slides to the blocking plate 103 through the placement plate 102 in turn, and continues to be blocked by the blocking plate 103. Then the rotating rod motor 114 reverses, and drives the rotating column block 107 to slide to the left through the outer rotating rod 105 and the inner sliding rod 106. When the rotating gear 110 contacts the fixed rack 111, under the action of the fixed rack 111, the fence frame 109 takes the stainless steel guardrail 4 It rotates 180 degrees, and then the rotating column block 107 slides to the left with the fence frame 109. When the slope support block 113 brings the stainless steel guardrail 4 to the bottom of the clamp 208, the slope support block 113 and the stainless steel guardrail 4 rise under the action of the concave track 1041, and the stainless steel guardrail 4 pushes the clamp 208 to rotate outward. When the stainless steel guardrail 4 rises to the highest point, the clamp 208 rotates back to its original position under the action of gravity and hooks into the hole at the top of the stainless steel guardrail 4. Then the rotating column block 107 continues to take the next stainless steel guardrail 4 with the fence frame 109, and the cycle continues.The transmission motor 204 rotates to drive the half-tooth gear 205 to rotate, thereby driving the docking gear 203 and the driving gear 202 to rotate intermittently, thereby driving the transmission belt 206 to rotate, thereby driving the rotating clamping frame 207 and the clamping claw 208 to move with the stainless steel guardrail 4. When the rotating clamping frame 207 and the clamping claw 208 bring the stainless steel guardrail 4 into the paint spraying room 301, the paint in the paint spraying tube 302 is pumped into the lower spray pipe 304 and the upper spray pipe 305 through the pump 303, and then enters the upper spray gun 309 and the lower spray gun 309. In the spray gun 306, the stainless steel guardrail 4 is sprayed with paint through the upper spray gun 309 and the lower spray gun 306. At the same time, the paint spraying motor 310 rotates to drive the lifting gear 311 to rotate, thereby driving the upper rack 308 to descend, and the lower rack 307 to rise, so that the upper spray gun 309 and the lower spray gun 306 can spray paint on the entire surface of the stainless steel guardrail 4. The excess paint flows into the return pipe 312 through the slope at the bottom of the paint spraying room 301, and returns to the paint spray barrel 302 through the one-way valve, so as to realize the recycling of the remaining paint. After the clamp 208 carries the stainless steel guardrail 4 to be sprayed in the paint spray room 301, the clamp 208 carries the stainless steel guardrail 4 into the drying box 212 and is dried by the burner 213. When the clamp 208 carries the stainless steel guardrail 4 to the top of the lifting slope block 210, the lifting slider 108 rises and just lifts the lifting rod 211, thereby driving the lifting slope block 210 to rise, and lifts the stainless steel guardrail 4 through the lifting end 2101, so that the stainless steel guardrail 4 is separated from the clamp 208. Then, under the action of the concave end 2102, the stainless steel guardrail 4 tilts and falls on the slope of the lifting slope block 210. At this time, the stainless steel guardrail 4 on the lifting slope block 210 can be removed manually.
