Background
Glass Fiber Reinforced Plastics (FRP), also known as GFRP, is a fiber reinforced plastic, generally a reinforced plastic made of a matrix of unsaturated polyester, epoxy resin and phenolic resin reinforced with glass fibers or products thereof, and is called glass fiber reinforced plastic, or glass fiber reinforced plastic, different from tempered glass.
Because of the variety of the resin used, there are polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic glass fiber reinforced plastics. Light weight, hardness, non-conductivity, stable performance, high mechanical strength, less recovery and corrosion resistance. Can replace steel to manufacture machine parts, automobile shells, ship shells and the like.
The glass fiber Reinforced plastic is known as Fiber Reinforced Plastic (FRP), i.e., fiber Reinforced composite plastic. The fiber is classified into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, and the like according to the difference of the adopted fiber. It is a composite material using glass fibre and its products (glass cloth, band, felt and yarn, etc.) as reinforcing material and synthetic resin as base material. The fiber reinforced composite material is composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10 mu m, the defects are few and small, the fracture strain is about thirty thousandths of a thousand, and the fiber (or whisker) is a brittle material and is easily damaged, fractured and corroded. The matrix is much lower in strength and modulus than the fibers, but can withstand large strains, tends to be viscoelastic and elastoplastic, and is a tough material.
In the existing glass fiber reinforced plastic manufacturing process, the technical requirement on glass fiber winding is not high, so that the existing glass fiber reinforced plastic is still at the level of manual winding. Namely, when the glass fiber reinforced plastic substrate needs to be treated, the glass fiber reinforced plastic substrate is rotated, then an operator manually holds the coiled glass fiber to be wound on the glass fiber reinforced plastic substrate, after the whole substrate is wound with the glass fiber, the temporary fixing is carried out, and the next working procedure is started. The biggest defect of manual winding is that the winding is uneven, and the thickness is not easy to master; meanwhile, the degree of tightness of winding between the glass fiber and the glass fiber reinforced plastic substrate cannot be uniformly controlled, and finally, the performance of the whole glass fiber reinforced plastic is reduced.
SUMMERY OF THE UTILITY MODEL

When utilizing the utility model discloses when carrying out the glass fiber winding, its theory of operation as follows: firstly, fixing the end of a single strand of glass fiber on the surface of a glass fiber reinforced plastic substrate 0 and approaching the position of the end; secondly, the glass fiber reinforced plastic substrate 0 is driven to rotate slowly by the supporting frame of the glass fiber reinforced plastic substrate 0, and then the output rotation speed of the driving mechanism 3 is determined according to the rotation speed of the glass fiber reinforced plastic substrate 0, the outer circumference of the glass fiber reinforced plastic substrate 0 and the width of the single glass fiber strand, if the prior art is the same. When the time taken by the glass fiber reinforced plastic substrate 0 to rotate for one circle is equal to the time taken by the feeding mechanism 8 to move the single-strand width of the glass fiber, the wound glass fiber is a single layer. That is, the whole glass fiber reinforced plastic substrate can be completely covered only by moving the feeding mechanism 8 for a time less than the time required for one rotation of the glass fiber reinforced plastic substrate 0. The multiple of the time required for the glass fiber reinforced plastic substrate 0 to rotate for one circle and the time for the feeding mechanism 8 to move for the width of a single glass fiber is equal to the number of layers of the glass fiber which is actually covered. During the actual winding process, the moving speed of the feeding structure 8 can be determined according to the actual winding thickness. However, the moving speed of the feeding mechanism 8 is determined by the driving mechanism 3. The driving mechanism 3 can be realized by a servo motor or a stepping motor, and certainly, can also be realized by the combination of a common motor and a speed reducer or a speed changer. Finally, when the glass fiber reinforced plastic substrate 0 rotates, the glass fiber is pulled out from the feeding mechanism 8 and wound while being pulled out, so that the consistent tightness can be ensured, and meanwhile, the glass fiber reinforced plastic substrate 0 and the feeding mechanism 8 are arranged at a constant speed, so that the problem that the tightness and the thickness uniformity cannot be controlled by manual winding in the center of the prior art is fundamentally avoided.

The guide wire tube 844 is the most important member, and has the function of guiding each glass fiber independently, ensuring that the glass fibers are wound on the glass fiber reinforced plastic substrate 0 in a tangent direction uniformly after being guided and separated individually, so that the optimal uniformity and tightness can be achieved, and the problem of non-uniform winding of the glass fibers caused by the gathering of multiple glass fibers is avoided. Each glass fiber can only pass through one wire guide tube 844 to ensure that the whole process of winding each glass fiber from the glass fiber to the glass fiber reinforced plastic base body 0 is in an independent tensioning state, and the problem that the performance is reduced due to the fact that the glass fiber is not uniformly wound on the glass fiber reinforced plastic base body 0 because of the gathering of multiple fibers but not tensioning is solved.
In this embodiment, the cross bar 842 is provided with wire fixing holes 845 corresponding to the positions of the wire guide tubes 844 one by one and communicated with the wire guide tubes 844; an elastic plug 843 is arranged in the thread fixing hole 845 in a matching manner. The plug 843 is provided to prevent the glass fibers on the glass fiber roll from being loosened and unfavorable to adjustment when the tightness of the glass fibers needs to be adjusted, so that in this case, the plug 843 only needs to be pressed into the thread fixing hole 845, the elastic plug 843 can fix the glass fibers and achieve the effect of constant pressure breakage, and operational conditions are provided for carding and tensioning the glass fibers.
