Description

Technical Field

[0001] The utility model relates to the technical field of fiber feeding equipment, in particular to a mixed fiber precise feeding device. Background Art

[0002] Hybrid fiber is a composite material formed by mixing two or more fibers. It is usually added to concrete to form precast concrete products, which can effectively increase the mechanical properties of precast concrete products. During the production process, the hybrid fiber and concrete need to be mixed in a certain proportion. At present, during the mixing operation, a certain amount of hybrid fiber is usually weighed manually, and then the weighed hybrid fiber is manually added to the concrete for mixing and stirring. However, since the hybrid fibers are usually entangled together and the entanglement is relatively tight, it is difficult to evenly mix the hybrid fibers in the concrete using the stirring force of the mixing station, resulting in inconsistent mechanical properties of the product, affecting the quality and consistency of the precast concrete products. The utility model patent with authorization announcement number CN214779402U discloses a polyester staple fiber feeding device with controllable feeding amount, including a hopper, a feeding box and a base. A baffle plate is arranged at the lower part of one side wall of the hopper, an electric push rod is arranged at the end of the baffle plate away from the hopper, a fixed frame is arranged at the end of the electric push rod away from the baffle plate, a feeding box is arranged at the lower end of the fixed frame, an air blowing pipe is connected to the middle part of one end of the feeding box through a flange, and an air pump is arranged at the end of the air blowing pipe away from the feeding box. The feeding amount of polyester staple fiber can be conveniently controlled through the weighing data of the pressure sensor and by controlling the opening and closing of the baffle plate to achieve the purpose of feeding on demand, but when the length of the fiber is large, the mutually entangled fibers cannot be effectively separated and the mixing effect is poor.
