Description

Technical Field

[0001] The present invention relates to the technical field of corrugated pipe processing equipment, and more specifically, it relates to a processing method and a processing device for plastic-steel corrugated pipes. Background Technique

[0002] A corrugated pipe refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescoping direction. During the production process of the corrugated pipe, it is necessary to spray a protective layer on the outer wall of the corrugated pipe so that the corrugated pipe can adapt to different environments. Since the outer wall of the corrugated pipe is continuously and alternately provided with protrusions and depressions, during the process of spraying the protective layer, the protective layer at the protrusion will slide along the protrusion towards the depression, resulting in uneven spraying of the protective layer. Summary of the Invention

[0003] The present invention provides a processing method and a processing device for plastic-steel corrugated pipes, which solve the technical problem of uneven spraying of the protective layer on the corrugated pipe in the related art.

[0004] The present invention provides a processing device for plastic-steel corrugated pipes, which includes a mounting frame and a carrier frame. One end of the carrier frame is slidably connected to the mounting frame through a second connecting shaft. A limiting groove for restricting the horizontal sliding of the carrier frame is provided on the mounting frame. The second connecting shaft is rotatably connected to the carrier frame. Clamping parts are oppositely arranged at both ends of the carrier frame, and the clamping parts are rotatably mounted on the carrier frame. One side of the mounting frame is provided with a first driving component for driving the other end of the carrier frame to perform circular motion. The other end of the carrier frame is rotatably connected to the output end of the first driving component through a first connecting shaft. A paint delivery pipe is installed on the upper part of the carrier frame. The paint delivery pipe is arranged along the length direction of the carrier frame, and nozzles are arranged along the length direction on the vertically downward side of the paint delivery pipe. When the first driving component drives the other end of the carrier frame to rotate, one end of the carrier frame slides along the length direction of the mounting frame. A second driving component is further provided on the carrier frame, and the second driving component is used to drive a group of clamping parts to rotate.

[0005] Further, the carrier frame includes a first plate and a second plate. The first plate and the second plate are fixedly connected through a second connecting rod. Both ends of the paint delivery pipe are connected to the first plate and the second plate through a connecting frame. The second connecting shaft is rotatably connected to the second plate, and the end of the second connecting shaft away from the second plate is slidably connected to the mounting frame through a slider, and the slider is matched with the limiting groove.

[0006] Further, the first driving component includes a support frame. The support frame is vertically arranged, and a first motor is installed at the upper end of the support frame. The output shaft of the first motor is installed with a first connecting rod. The first connecting rod is arranged radially along the output shaft of the first motor. The first connecting shaft is fixedly installed on the first plate, and the first connecting shaft is rotatably connected to the end of the first connecting rod away from the output shaft of the first motor.

[0007] Further, the clamping part includes a first mounting seat and a second mounting seat. Fixed blocks are installed on both the first plate and the second plate. The two groups of fixed blocks are arranged oppositely. The first mounting seat is rotatably connected to the corresponding fixed block. A number of limiting rods are installed on the first mounting seat. The limiting rods are all arranged perpendicular to the first mounting seat, and the ends of the limiting rods far from the first mounting seat all penetrate through the second mounting seat to connect the clamping jaws. The clamping jaws are all rotatably connected to the ends of the limiting rods, and adjusting rods are rotatably installed on the clamping jaws. The adjusting rods are arranged on the side of the clamping jaws close to the limiting rods, and the ends of the adjusting rods far from the clamping jaws are rotatably connected to the second mounting seat. A driving member is also installed on the first mounting seat, and the driving member drives the second mounting seat to approach or move away from the first mounting seat.

[0008] Further, the driving member is a cylinder. The cylinder is installed on the side of the first mounting seat facing the second mounting seat, and the output shaft of the cylinder is fixedly connected to the second mounting seat.

[0009] Further, the second driving assembly includes a second motor. The second motor is installed on the first plate or the second plate. A first gear is installed on the output shaft of the second motor. A second gear is sleeved on the outer wall of a group of first mounting seats. The first gear and the second gear mesh with each other.

[0010] Further, arc-shaped plates are installed at the ends of the clamping jaws far from the second mounting seat. The arc-shaped plates are rotatably connected to the corresponding clamping jaws, and the arc-shaped surfaces of the arc-shaped plates face the outside of the clamping jaws.

[0014] S1: One end of the pipe body is sleeved on a group of the clamping parts, the pipe body is moved towards the clamping part, and then the other end of the pipe body is sleeved on another group of clamping parts;

[0015] S2: The clamping part opens and fixes the pipe body from the inside of the pipe body;

[0016] S3: The paint delivery pipe sprays protective paint on the outer wall of the pipe body through the nozzle. The first driving assembly drives the end of the carrier frame to move in a circular motion and drives the other end of the carrier frame to slide along the length direction of the mounting frame. At the same time, the second driving member drives the clamping part to drive the pipe body to rotate synchronously;

[0017] S4: After the spraying of the pipe body is completed, the nozzle stops spraying paint, and the first driving assembly and the second driving assembly stop driving;

[0018] S5: The clamping part releases the tube body and removes the tube body from the carrier;

[0019] S6: Repeat the above steps S1 to S5 until the processing of the entire tube body is completed.

[0020] The beneficial effects of the present invention are:

[0021] The present invention proposes a plastic-steel corrugated pipe processing device, which, through the cooperation of a first drive component and a second drive component, lowers one end of the pipe body toward the moving direction, or raises the other end of the pipe body away from the moving direction when the pipe body moves, and slows down the flow speed of the protective paint on the first slope or the second slope on the pipe body through the effect of inertia. Through the superposition of the two movement effects, the protective paint can be evenly sprayed on the outer wall of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1

[0033] As Figures 1-8 shown, a processing device for plastic-steel corrugated pipes includes a mounting frame 4 and a bearing frame 2. One end of the bearing frame 2 is slidably connected to the mounting frame 4 through a second connecting shaft 221.

The other end of the bearing frame 2 is rotatably connected to the output end of the first driving component through a first connecting shaft 13. A paint delivery pipe 5 is installed on the upper part of the bearing frame 2. The paint delivery pipe 5 is arranged along the length direction of the bearing frame 2, and spray nozzles 51 are arranged along the length direction on the side of the paint delivery pipe 5 facing vertically downward. When the first driving component drives the other end of the bearing frame 2 to rotate, one end of the bearing frame 2 slides along the length direction of the mounting frame 4. A second driving component is also provided on the bearing frame 2, and the second driving component is used to drive a group of clamping parts 3 to rotate.

[0034] It should be noted that in specific implementation, to ensure uniform distribution on the outer wall of the pipe body 7, the protective paint sprayed by the spray nozzles 51 can cover only one-sixth of the circumference of the pipe body 7. Moreover, the processing equipment further includes a tank for storing the protective paint and a pump for delivering the protective paint. The tank and the pump both adopt existing technologies and will not be elaborated here.

[0035] The bearing frame 2 includes a first plate 21 and a second plate 22. The first plate 21 and the second plate 22 are fixedly connected through a second connecting rod 23.

[0036] The first driving component includes a support frame 11 which is vertically arranged. A first motor 1 is installed at the upper end of the support frame 11. A first connecting rod 12 is installed on the output shaft of the first motor 1. The first connecting rod 12 is arranged radially along the output shaft of the first motor 1. A first connecting shaft 13 is fixedly installed on the first plate 21. The first connecting shaft 13 is rotationally connected to the end of the first connecting rod 12 far from the output shaft of the first motor 1.

[0037] The clamping part 3 includes a first mounting seat 31 and a second mounting seat 34. Fixed blocks 211 are installed on both the first plate 21 and the second plate 22. The two groups of fixed blocks 211 are arranged oppositely. The first mounting seat 31 is rotationally connected to the corresponding fixed block 211. A plurality of limiting rods 33 are installed on the first mounting seat 31. The limiting rods 33 are all arranged perpendicular to the first mounting seat 31. And the ends of the limiting rods 33 far from the first mounting seat 31 all penetrate through the second mounting seat 34 to connect the clamping jaws 36. The clamping jaws 36 are all rotationally connected to the ends of the limiting rods 33. And adjusting rods 35 are rotatably installed on the clamping jaws 36. The adjusting rods 35 are arranged on the side of the clamping jaws 36 close to the limiting rods 33. And the ends of the adjusting rods 35 far from the clamping jaws 36 are rotationally connected to the second mounting seat 34. A driving member is further installed on the first mounting seat 31. The driving member drives the second mounting seat 34 to approach or move away from the first mounting seat 31.

[0038] The driving member is a cylinder 32. The cylinder 32 is installed on the side surface of the first mounting seat 31 facing the second mounting seat 34. And the output shaft of the cylinder 32 is fixedly connected to the second mounting seat 34.

[0039] The second driving component includes a second motor 6. The second motor 6 is installed on the first plate 21 or the second plate 22. A first gear 61 is installed on the output shaft of the second motor 6. A second gear 62 is sleeved on the outer wall of a group of first mounting seats 31. The first gear 61 meshes with the second gear 62.

[0040] Arc-shaped plates 361 are installed at the ends of the clamping jaws 36 far from the second mounting seat 34. The arc-shaped plates 361 are rotationally connected to the corresponding clamping jaws 36. And the arc-shaped surfaces of the arc-shaped plates 361 face the outside of the clamping jaws 36. Anti-slip pads are arranged on the arc-shaped surfaces of the arc-shaped plates 361.

[0041] The output shaft of the first motor 1 and the central axis of the clamping part 3 are in the same horizontal plane.

[0042] There are three groups of limiting rods 33 and clamping jaws 36. And the limiting rods 33 are installed at equal angles on the side wall of the first mounting seat 31 facing the second mounting seat 34.

[0043] Embodiment 2

[0044] In this embodiment, a processing method of the plastic-steel corrugated pipe processing device as described above is proposed, mainly aiming at the protective paint with a fast solidification speed. The steps are as follows:

[0045] When the device is in use, place the pipe body 7 to be sprayed between the two sets of clamping parts 3. After adjusting the position of the pipe body 7, start the air cylinder 32. The air cylinder 32 pulls the second mounting seat 34 towards the first mounting seat 31. The second mounting seat 34 slides along the length direction of the limit rod 33 and drives the adjusting rod 35 to move towards the end away from the clamping jaw 36. One end of the adjusting rod 35 connected to the clamping jaw 36 pulls the clamping jaw 36 to expand outwards until the clamping jaw 36 is fixed to the inner wall of the pipe body 7;

[0046] Next, the spray head 51 evenly sprays on one-sixth area of the outer wall of the pipe body 7. After the spraying is completed, the spray head 51 pauses. At the same time, the first motor 1 is started;

[0047] The first motor 1 drives the first connecting rod 12 to rotate forward by 90 degrees. The first connecting rod 12 drives the first plate 21 to move synchronously through the first connecting shaft 13. During this process, the first plate 21 pulls the second plate 22 to move through the second connecting rod 23, and the second plate 22 drives the slider 222 to slide horizontally along the limit groove 41;

[0048] At the same time, the first plate 21 drives the first connecting shaft 13 to rotate, and the second plate 22 drives the second connecting shaft 221 to rotate, keeping the clamping parts 3 on the first plate 21 and the second plate 22 always facing each other;

[0049] During the forward rotation of the first motor 1, the carrier 2 drives the pipe body 7 to move towards the position where the first plate 21 is located. The protective paint flowing from the top of the convex part 71 to the first slope 711 on the outer wall of the pipe body 7 moves in the opposite direction relative to the first slope 711 of the pipe body 7 under the action of inertia, and the flow trend of the protective paint flowing from the convex part 71 to the lower part of the second slope 712 is accelerated. Since during the movement of the pipe body 7, one end of it at the first plate 21 moves downward, driving one end of the pipe body 7 at the first plate 21 to deflect downward, the flow trend of the protective paint flowing from the top of the convex part 71 on the outer wall of the pipe body 7 to the lower part of the second slope 712 is slowed down;

[0050] When the first motor 1 drives the first connecting rod 12 to rotate to the vertical state, the initially sprayed protective layer solidifies. At this time, the thickness of the protective paint above the first slope 711 is greater than the thickness of the protective paint below the first slope 711, and the thickness of the protective paint below the second slope 712 is greater than the thickness of the protective paint above the second slope 712;

[0051] Next, the first motor 1 drives the first connecting rod 12 to continue rotating by 90 degrees. At this time, the first connecting shaft 13 drives the first plate 21 to continue moving synchronously. The first plate 21 pulls the second plate 22 to continue moving through the second connecting rod 23, and the second plate 22 drives the slider 222 to slide to the end of the limit groove 41 close to the first motor 1;

[0052] At this time, the carrier 2 and the pipe body 7 both return to the horizontal state, the first motor 1 pauses, and then the spray head 51 evenly sprays the same amount of protective paint again in the area of the first spray. After the spraying is completed, the spray head 51 pauses and the first motor 1 starts again;

[0053] As the first motor 1 continues to rotate and drives the first connecting rod 12 to continue rotating, the first connecting rod 12 drives the first plate 21 to rotate towards the direction where the second plate 22 is located, and pushes the second plate 22 to move in the reverse direction through the second connecting rod 23. The second plate 22 drives the slider 222 to slide reversely along the limiting groove 41;

[0054] At the same time, the first plate 21 drives the first connecting shaft 13 to rotate, and the second plate 22 drives the second connecting shaft 221 to rotate, keeping the clamping parts 3 on the first plate 21 and the second plate 22 always facing each other;

[0055] During the continuous rotation of the first motor 1, the carrier 2 drives the pipe body 7 to move towards the position where the second plate 22 is located. The protective paint flowing from the top of the convex part 71 to the second slope 712 on the outer wall of the pipe body 7 moves reversely relative to the second slope 712 of the pipe body 7 under the action of inertia, and the flowing trend of the protective paint flowing from the convex part 71 to the lower part of the first slope 711 is accelerated. Since during the movement of the pipe body 7, one end of it at the first plate 21 moves upward, driving one end of the pipe body 7 at the first plate 21 to deflect upward, the flowing trend of the protective paint flowing from the top of the convex part 71 on the outer wall of the pipe body 7 to the lower part of the second slope 712 is slowed down;

[0056] When the first connecting rod 12 rotates to the vertical state again, the protective paint sprayed for the second time solidifies. At this time, due to the second movement of the pipe body 7, the thickness of the protective paint at the upper part of the second slope 712 of the protective paint sprayed for the second time is greater than the thickness of the protective paint at the lower part of the second slope 712, and the thickness of the protective paint at the lower part of the first slope 711 is greater than the thickness of the protective paint at the upper part of the first slope 711, balancing the distribution of the protective paint sprayed for the first time, so that the protective paint at the convex part 71, the first slope 711 and the second slope 712 on the outer wall of the pipe body 7 can be evenly distributed;

[0057] When the first motor 1 drives the first connecting rod 12 to rotate one week, the first motor 1 pauses. At the same time, the second motor 6 starts. The second motor 6 drives the corresponding clamping part 3 to rotate sixty degrees through the cooperation of the first gear 61 and the second gear 62. The clamping part 3 drives the pipe body 7 to rotate sixty degrees accordingly, so that the unsprayed area on the outer wall of the pipe body 7 corresponds to the spray head 51;

[0058] Then repeat the above operations. After spraying the outer wall of the pipe body 7 is completed, the air cylinder 32 pushes the second mounting seat 34 away from the first mounting seat 31. The second mounting seat 34 slides along the length direction of the limiting rod 33 and drives the adjusting rod 35 to move towards the position where the clamping jaws 36 are located. One end of the adjusting rod 35 connected to the clamping jaws 36 pushes the clamping jaws 36 to close inward until the clamping jaws 36 no longer restrict the pipe body 7. Then remove and replace the pipe body 7, and repeat the above operations to spray another pipe body 7.

[0059] Embodiment III

[0060] In this embodiment, a processing method for a plastic-steel corrugated pipe processing device is proposed, mainly aiming at the protective paint with a slow solidification rate. The steps are as follows:

[0061] Place the pipe body 7 to be sprayed between the two sets of clamping parts 3. After adjusting the position of the pipe body 7, start the air cylinder 32. The air cylinder 32 pulls the second mounting seat 34 towards the first mounting seat 31. The second mounting seat 34 slides along the length direction of the limiting rod 33 and drives the adjusting rod 35 to move towards the end far from the clamping jaws 36. One end of the adjusting rod 35 connected to the clamping jaws 36 pulls the clamping jaws 36 to expand outward until the clamping jaws 36 are fixed to the pipe body 7 by the inner wall thereof;

[0062] Next, the nozzle 51 continuously sprays evenly on one-sixth area of the outer wall of the pipe body 7. At the same time, the first motor 1 and the second motor 6 are started;

[0063] When the second motor 6 is started, it drives the corresponding clamping part 3 to rotate through the first gear 61 and the second gear 62. The clamping part 3 drives the pipe body 7 to rotate at a constant speed to adjust the area of the pipe body 7 surface corresponding to the nozzle 51;

[0064] When the first motor 1 is started, it drives the first connecting rod 12 to rotate. The first connecting rod 12 drives the first plate 21 to move synchronously through the first connecting shaft 13. During this process, the first plate 21 pulls the second plate 22 to move through the second connecting rod 23. The second plate 22 drives the slider 222 to slide horizontally along the limiting groove 41;

[0065] At the same time, the first plate 21 drives the first connecting shaft 13 to rotate, and the second plate 22 drives the second connecting shaft 221 to rotate, so as to keep the clamping parts 3 on the first plate 21 and the second plate 22 always facing each other;

[0066] When the first motor 1 drives the first connecting rod 12 to rotate from 0° to 90°, the carrier 2 drives the pipe body 7 to move towards the position where the first plate 21 is located. The protective paint flowing on the outer wall of the pipe body 7 from the top of the convex portion 71 to the first slope 711 moves in the opposite direction relative to the first slope 711 of the pipe body 7 under the action of inertia, and the flow trend of the protective paint flowing from the convex portion 71 to the lower part of the second slope 712 is accelerated. Since during the movement of the pipe body 7, one end of it at the first plate 21 moves downward, driving one end of the pipe body 7 at the first plate 21 to deflect downward, the flow trend of the protective paint flowing from the top of the convex portion 71 on the outer wall of the pipe body 7 to the lower part of the second slope 712 is slowed down to a certain extent;

[0067] When the first motor 1 drives the first connecting rod 12 to rotate from 90° to 180°, the first connecting shaft 13 drives the first plate 21 to continue to move synchronously. The first plate 21 pulls the second plate 22 to continue to move through the second connecting rod 23. The second plate 22 drives the slider 222 to slide towards the end of the limiting groove 41 close to the first motor 1. During this process, the height of the first plate 21 gradually rises, driving the pipe body 7 to rotate in the horizontal direction. Under the action of inertia, it moves in the opposite direction relative to the first slope 711 of the pipe body 7, and the flow trend of the protective paint flowing from the convex portion 71 to the lower part of the second slope 712 is accelerated, resulting in a large thickness of the protective paint at the lower part of the second slope 712;

[0068] When the first motor 1 drives the first connecting rod 12 to rotate from 180° to 270°, the carrier 2 drives the pipe body 7 to move towards the position where the second plate 22 is located. The protective paint flowing on the outer wall of the pipe body 7 from the top of the convex portion 71 to the second slope 712 moves in the opposite direction relative to the second slope 712 of the pipe body 7 under the action of inertia, and the flow trend of the protective paint flowing from the convex portion 71 to the lower part of the first slope 711 is accelerated. Since during the movement of the pipe body 7, one end of it at the first plate 21 moves upward, driving one end of the pipe body 7 at the first plate 21 to deflect upward, the flow trend of the protective paint flowing from the top of the convex portion 71 on the outer wall of the pipe body 7 to the lower part of the second slope 712 is slowed down;

[0069] When the first motor 1 drives the first connecting rod 12 to rotate from 270° to 360° / 0°, the first connecting rod 12 drives the first plate 21 to continue to rotate and pushes the second plate 22 to move in the opposite direction through the second connecting rod 23. The second plate 22 drives the slider 222 to slide along the limiting groove 41 in the opposite direction. During this process, the height of the first plate 21 gradually decreases, driving the pipe body 7 to rotate in the horizontal direction. Under the action of inertia, it moves in the opposite direction relative to the second slope 712 of the pipe body 7, and the flow trend of the protective paint flowing from the convex portion 71 to the lower part of the first slope 711 is accelerated. After the spraying position on the pipe body 7 rotates 360°, it solidifies;

[0070] Through the mutual balance of the first connecting rod 12 rotating from 0° to 180° and from 180° to 360° / 0°, the protective paint sprayed on the outer wall of the pipe body 7 can be evenly distributed;

[0071] After the outer wall of the pipe body 7 is completely sprayed with protective paint, the spray head 51 pauses. When the area where the protective paint is finally sprayed on the pipe body 7 rotates 360°, the second motor 6 pauses, and the first motor 1 pauses after driving the first connecting rod 12 to rotate from 270° to 360° / 0°;

[0072] After the spraying of the outer wall of the pipe body 7 is completed, the air cylinder 32 pushes the second mounting seat 34 away from the first mounting seat 31. The second mounting seat 34 slides along the length direction of the limiting rod 33 and drives the adjusting rod 35 to move towards the position where the clamping jaws 36 are located. One end of the adjusting rod 35 connected to the clamping jaws 36 pushes the clamping jaws 36 to close inward until the clamping jaws 36 no longer restrict the pipe body 7. Then, the pipe body 7 is removed and replaced, and the above operation is repeated to spray another pipe body 7.

[0073] The embodiments of this example have been described above, but this example is not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this example, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this example.
