Description

Online monitoring and straightening system for large-width carbon fiber plate

Technical Field

The application relates to the technical field of carbon fiber plate manufacturing, in particular to a large-width carbon fiber plate on-line monitoring and straightening system.

Background

With the increasing importance of bridge reconstruction and reinforcement engineering, research on bridge reinforcement methods inside and outside the industry is increasing. The reinforcement of the bridge is divided into bearing capacity reinforcement and crack reinforcement, and the concrete reinforcement methods for the building at present mainly include an enlarged cross section reinforcement method, an external prestress reinforcement method, an external wrapping steel reinforcement method, a steel plate bonding reinforcement method, a fiber composite material bonding reinforcement method and the like. Among them, the reinforcing method of the bonded steel and the coated steel has a great increase in the self weight of the building, and the steel material is easily rusted and has poor corrosion resistance and durability, and is gradually replaced by a carbon fiber reinforcing material with more excellent comprehensive performance in recent years.

The carbon fiber has the density only one tenth of that of steel materials, high specific strength, excellent corrosion resistance and durability, good damping performance, similar thermal expansion coefficient to that of concrete and very wide application prospect. The application form of carbon fiber reinforcement mainly comprises carbon fiber cloth and a carbon fiber plate. The carbon fiber cloth and the carbon fiber plate can be directly pasted at the weakest part of a concrete structure member by adopting adhesives such as epoxy structural adhesive and the like, and form a unified whole with the reinforced member, so that the development of cracks is limited, the bearing capacity is improved, and the reinforcement of a building structure is realized. In addition, the carbon fiber plate can be actively reinforced, namely, prestress is applied under the cooperation of the anchorage device, so that the structural deformation is effectively reduced, and the crack width is reduced. The width specifications of the common carbon plates in the current market are as follows: 100mm, 50mm and 20mm, thickness having: 1.2mm, 1.4mm, 2.0mm, 3.0mm, 4.0mm and the like. The carbon plates are suitable for reinforcing narrow beams, when large-width beams are reinforced, a plurality of carbon plates with the width of 100mm or 50mm are needed to be transversely and parallelly adhered, the problem of uneven stress transfer is easily caused by the adhering mode, the construction amount is large, and the labor cost is increased. The effective measure for solving the problem is to manufacture a large-width carbon fiber plate, wherein the width of the large-width carbon fiber plate is 150-300mm, and the thickness of the large-width carbon fiber plate is 1.2-3.0 mm;

the existing carbon fiber plate manufacturing process is to hang carbon fibers on a creel, the quantity of hung yarns is calculated and determined according to the specification of the produced carbon plate, and the carbon fibers are uniformly distributed and arranged by utilizing a yarn collecting plate. After the carbon fiber yarn bundle is impregnated with the epoxy resin and the curing agent, the carbon fiber yarn bundle is sequentially processed by a cold die (pre-extrusion), a hot die (curing and extrusion), traction equipment and a winding mechanism, and finally packaged into a finished product. The large-width carbon fiber plate is wider in width, contains more carbon fibers, is wider in distribution range, and easily causes the problem of longitudinal bending in the production process. The existing process cannot identify the problem in time, and because the rolling length specification of the carbon plate is generally 100m, if the problem of bending occurs, a large number of carbon plates are defective, so that raw materials and manpower are wasted, and the production cost is increased.
