Conveying device capable of effectively controlling unwinding tension

Abstract

Disclosed is a conveying device capable of effectively controlling unwinding tension. The conveying device comprises an unwinding mechanism, a yarn threading mechanism, a fixed yarn spreading roll set and a yarn spreading mechanism, wherein the unwinding mechanism, the yarn threading mechanism, the fixed yarn spreading roll set and the yarn spreading mechanism are arranged in sequence. The conveying device is characterized in that the ends of yarn spreading rolls of the fixed yarn spreading roll set are installed in a connected mode through elastic assemblies, silica gel layers and wear-resistant layers are arranged on the surfaces of the yarn spreading rolls in sequence, resistance strain gauge pressure sensors are arranged between each wear-resistant layer and the corresponding silica gel layer, and connected with a wireless communication module, and the wireless communication module is connected with a display screen in a wireless connection mode. According to the conveying device, due to the fact that the elastic assemblies are added to the fixed yarn spreading roll set, the problem that by the adoption of an existing technical device, carbon fibers are prone to fuzzing and twisting and prone to being damaged is solved, the product quality and the production efficiency are improved, the tension can also be effectively controlled, the yarn spreading effect of the carbon fibers is further improved, and the yarn spreading width of carbon fiber prepreg is increased.

Description

technical field [0001] The invention belongs to the technical field of textile equipment and relates to a conveying device for effectively controlling unwinding tension. Background technique [0002] Products have the following effects: [0003] 1. The wool affects the appearance quality of the fiber and affects the appearance of the finished product; [0004] 2. The wool will pollute the environment, affect the health of the staff, and cause damage to the human respiratory system and pores; [0005] 3. In the process of production and processing, the wool will reduce the fiber strength and increase the dispersion coefficient. The wool will prevent the resin matrix from fully soaking the carbon fiber, and it is easy to produce voids in the preparation of composite materials, thus affecting the mechanical properties of the composite material. ; [0006] 4. Fuzz will also have an impact on the working environment, which may cause short-circuit accidents such as electrical e...

[0003] 1. The wool affects the appearance quality of the fiber and affects the appearance of the finished product;

[0004] 2. The wool will pollute the environment, affect the health of the staff, and cause damage to the human respiratory system and pores;

[0005] 3. In the process of production and processing, the wool will reduce the fiber strength and increase the dispersion coefficient. The wool will prevent the resin matrix from fully soaking the carbon fiber, and it is easy to produce voids in the preparation of composite materials, thus affecting the mechanical properties of the composite material. ;

[0006] 4. The wool will also have an impact on the working environment, which may cause short-circuit accidents such as electrical equipment and instruments, and seriously affect production and safety.

[0009] The spring tension of the bobbin will make the carbon fiber in the unwinding mechanism to the stretching mechanism very tense, and the resulting friction between the carbon fiber on the unwinding mechanism and the ceramic hole fixing plate and the rear steering auxiliary roller will be corresponding. If it increases, it is easy to cause carbon fiber damage and serious fluffing problems, and there is a certain probability that the fibers will be twisted, which will affect production
