Description

Technical Field

[0001] The invention relates to the technical field of building reinforcement, and in particular to a composite fiberboard for building material surface reinforcement and a processing method and device thereof. Background Art

[0002] Building reinforcement is the use of carbon fiber, steel bonding, and high-pressure grouting to strengthen buildings. This technology is widely used in design changes, reinforcement and change projects such as adding beams, columns, cantilever beams, and plates. It is a connection technology for post-anchoring steel bars using structural adhesives in building structure seismic reinforcement projects. It is the best choice for structural reinforcement and heavy load fastening applications. In the construction of reinforced concrete structures, the steel bars for plate and beam structure adjustment are used to strengthen prefabricated beams for repair and rebar planting. Curtain wall embedded billboard anchoring, mechanical equipment installation rebar anchoring, etc. Anchoring of rock brick masonry, stone dry hanging curtain wall. Stone bonding, anchoring support for mine cave roofs and walls; anchoring of railway tracks, various anchoring of water conservancy facilities, docks, highways, bridges, tunnels, subways and other projects.

[0003] At present, the moisture resistance of fiberboard is poor, and the expansion coefficient is large after absorbing moisture, which causes the board to warp and deform due to the difference in expansion force after moisture absorption during use, thereby shortening the service life of the fiberboard; secondly, the flap cooler is one of the equipment needed in the fiberboard processing process. However, when the flap cooler is in use, the flap is always rotating, resulting in a shorter contact time between the fiberboard and the cold air inside the chassis. At the same time, there will be a blind spot when the cold air inside the chassis is sprayed, resulting in uneven cooling of the fiberboard, thereby reducing the cooling effect of the fiberboard.

[0004] Therefore, a composite fiberboard for reinforcing the surface of building materials and a processing method and device thereof are proposed. Summary of the invention

[0107] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0108] In practical application

[0109] S1. Start the second motor 605. The output shaft of the second motor 605 drives the second active pulley 606 to rotate. The second active pulley 606 drives the second driven pulley 607 to rotate through the belt. The second driven pulley 607 drives the active roller 602 to rotate. The active roller 602 drives the driven roller 603 to rotate through the conveyor belt, thereby conveying the fiberboard to be cooled. When the fiberboard is conveyed to the inner cavity of the cooling box 2 by the transmission belt of the inner cavity of the shield 608, the fiberboard is placed between the corresponding front and rear L-shaped clamping plates 303, so that the two rows of rollers 304 on the inner wall of the L-shaped clamping plate 303 clamp it.

[0110] S2, start the air cooler 7 and the first motor 502, the air cooler 7 sends cold air to the inner cavity of the cooling box 2, the output shaft of the first motor 502 drives the support rod 503, the limit ring 504 and the lever 505 to rotate, when the lever 505 rotates more than 180 degrees, the lever 505 moves the convex column 508 located in the inner cavity of the limit ring 504, so that the convex column 508 drives the disc 507, the movable column 506, the hollow shaft 301, the collar 302, the L-shaped clamping plate 303 and the roller 304 to rotate synchronously, thereby making the clamped fiberboard rotate synchronously, at the same time, when the disc 507 rotates a certain angle, the limit ring 504 The opening of the corresponding disk 507 rotates to one side of the disk 507, and the limiting ring 504 uses the opening on its surface to limit the two corresponding convex columns 508, so that the disk 507, the movable column 506, the hollow shaft 301, the collar 302, the L-shaped clamping plate 303 and the roller 304 rotate a certain angle. When the lever 505 rotates to 360 degrees, the limiting ring 504 and the lever 505 return to the original state. Therefore, each rotation of the lever 505 will drive the clamping mechanism 3 to rotate a certain angle with the movable column 506 as the axis, and repeat the cycle, so that the clamping mechanism 3 rotates intermittently, so as to clamp and flip the next fiberboard;

[0111] S3, the output shaft of the first motor 502 also drives the first driving pulley 510 to rotate, the first driving pulley 510 drives the first driven pulley 511 to rotate through the belt, the first driven pulley 511 drives the worm 509 to rotate, the worm 509 drives the worm wheel 514, the rotating rod 513 and the L-shaped rod 515 to rotate synchronously, the end of the L-shaped rod 515 rotates in the inner cavity of the hollow frame 408, when the L-shaped rod 515 rotates ninety degrees clockwise, the L-shaped rod 515 drives the hollow frame 408, the movable rod 407, the round rod 406 and the rectangular frame 405 to move horizontally toward the inner cavity of the cooling box 2 synchronously, and the inner wall surface of the rectangular frame 405 drives the connecting column 404 to move, so that the connecting column 404 04 drives the fan plate 402 to rotate forward with the axis of the square rod 401 surface. When the L-shaped rod 515 rotates 270 degrees clockwise, the connecting column 404 eventually drives the fan plate 402 to rotate backward with the axis of the square rod 401 surface. When the L-shaped rod 515 rotates 360 degrees clockwise, the connecting column 404 eventually drives the fan plate 402 to rotate forward with the axis of the square rod 401 surface. Therefore, each rotation of the L-shaped rod 515 will drive the fan plate 402 to swing back and forth once with the axis of the square rod 401 surface, and the cycle repeats, so that the fan plate 402 swings back and forth, so that the cold air spreads to every corner of the inner cavity of the cooling box 2, thereby performing all-round cooling treatment on the fiberboard.

[0112] S4. When the fiberboard rotates to the other side of the conveyor belt under the action of the clamping mechanism 3, the fiberboard can slide to the top of the conveyor belt under the action of the active roller 602 and the driven roller 603, thereby completing the flap cooling process.

[0113] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
