Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber production, in particular to a carbon fiber gluing machine. Background Art

[0002] Carbon fiber is a high-strength, high-modulus fiber material with a carbon content of more than 95%. It is made of organic fibers such as flaky graphite microcrystals stacked along the axial direction of the fiber, and is a microcrystalline graphite material obtained through carbonization and graphitization. Carbon fiber has the characteristics of "soft outside and hard inside". It is lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. Carbon fiber not only has the inherent intrinsic properties of carbon materials such as strong tensile strength, but also has the softness and processability of textile fibers. It is a new material with excellent mechanical properties and has broad application prospects in both national defense and civilian fields.

[0003] Carbon fiber is usually added as a reinforcing material to materials such as resin, metal, ceramic, concrete, etc. to form a composite material. The surface coating of adhesive is crucial for the further processing and utilization of carbon fiber, and the surface coating can also protect the carbon fiber products and improve their overall performance. However, since carbon fiber materials have a non-polar surface, ordinary adhesives have poor adhesion to this material and require special surface treatment to change its surface properties. In addition, the structure of carbon fiber is usually seen as consisting of two-dimensional ordered crystals and pores, in which the content, size and distribution of the pores directly affect the performance of the carbon fiber. This special structure of carbon fiber also determines the irregularity of the material plane, and its hollow structure is also prone to adsorbing gases and particles, which further increases the difficulty of adhesive bonding and gluing.

[0004] The existing gluing process mainly uses glue tanks for gluing, which is prone to glue dripping and uneven glue distribution. Due to the uneven distribution of glue, subsequent complex processes are required to correct it, which increases production costs. In addition, dripping glue may cause equipment contamination, requiring frequent maintenance and cleaning, affecting production efficiency. These problems have prompted people to seek a new gluing technology to improve production efficiency and product quality while reducing production costs and maintenance difficulties. Summary of the invention

[0005] The present invention aims to provide an improved carbon fiber gluing machine to solve the problems of glue dripping and uneven glue distribution in the existing gluing process. By adopting glue atomization spraying technology, more uniform and efficient gluing can be achieved, the demand for subsequent processes can be reduced, production efficiency can be improved, and the difficulty and cost of equipment maintenance can be reduced.
