Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of glass fiber cloth production equipment, specifically relating to a yarn cutting device. Background Technology
[0002] In the field of materials science, adding glass fibers to resins is an effective way to enhance their strength and performance. Glass fibers, with their high strength, high modulus, and good chemical stability, can significantly improve the relatively weak mechanical properties of resins. Composite materials formed by combining these two materials have wide applications in numerous industries, including aerospace, automotive manufacturing, and construction engineering.
[0003] In actual production, different resin prepregs have their own unique process requirements and performance indicators, so glass fiber yarn needs to be cut into different lengths according to these different needs. Glass fiber yarn is essentially a woven fabric made of glass fibers through a special process. This woven fabric structure makes it prone to weaving dispersion at the cut location. Once the weave disperses, the glass fiber yarn may be unevenly distributed in the resin, thus affecting the overall performance of the final composite material, reducing its strength and stability, and failing to meet product quality standards. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a yarn cutting device to solve the problem of easy dispersion of existing glass fiber yarn at the cutting position. The yarn cutting device provided by this utility model can fix the fibers at the cutting position of the glass fiber yarn at the same time as cutting, so as to prevent it from dispersing.
[0005] This utility model discloses a yarn cutting device, including a glass fiber yarn supply device, a first support platform, a second support platform, a first guide roller, a second guide roller, a lifting mechanism, a lifting seat, a cutting blade, a first bonding resin tank, a second bonding resin tank, a first sponge, and a second sponge. The first support platform and the second support platform are arranged side by side with a gap. The first guide roller is located on the first support platform, and the second guide roller is located on the second support platform. The glass fiber yarn supplied by the glass fiber yarn supply device passes sequentially between the first guide roller and the first support platform and between the second guide roller and the second support platform. The lifting mechanism is connected to the lifting seat. The cutting blade is located below the lifting seat and between the first support platform and the second support platform. The first bonding resin tank and the second bonding resin tank are located on both sides of the cutting blade. The first sponge is located below the first bonding resin tank, and the second sponge is located below the second bonding resin tank. A first cotton rope is threaded between the first bonding resin tank and the first sponge, and a second cotton rope is threaded between the second bonding resin tank and the second sponge.
[0006] Furthermore, a first heating device is provided on the first support platform corresponding to the position of the first sponge, and a second heating device is provided on the second support platform corresponding to the position of the second sponge.
[0007] Furthermore, the lifting mechanism is a lifting cylinder.
[0008] The yarn cutting device provided by this utility model has a first sponge and a second sponge respectively provided on both sides of the cutting blade. The first bonding resin tank maintains the supply of resin adhesive in the first sponge through the first cotton rope, and the second bonding resin tank maintains the supply of resin adhesive in the second sponge through the second cotton rope. When the cutting blade cuts the glass fiber yarn downwards, the resin adhesive can be applied to the glass fiber yarn on both sides of the cutting position by squeezing the first sponge and the second sponge, thereby avoiding the problem of the glass fiber spreading at the cutting position and ensuring the integrity of the cut glass fiber yarn.
