All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 6, the present invention provides a novel apparatus for preparing composite fiber for aerial work, and the apparatus mainly includes: the device comprises a pay-off device 1, a gum dipping device 2, a bundling device 3, a twisting device 4 and a winding device 5 which are arranged in sequence along the forming direction of the composite fiber. Wherein, coiling mechanism 5 includes:

a cutter assembly 51 for cutting the composite fibers;

a winding roller 52 for winding the composite fibers, wherein the winding roller 52 is positioned below the blanking assembly 51, so that the composite fibers can be vertically and downwardly conveyed, and the conveying speed of the composite fibers is equal to the winding speed of the winding roller 52;

the second storing mechanism 54 is arranged between the cutting assembly 51 and the winding roller 52, the second storing mechanism 54 is used for discharging when the cutting assembly 51 cuts the composite fibers, storing when the cutting assembly 51 returns after cutting, and the discharging speed and the storing speed are equal to the winding speed of the winding roller 52;

the feeding roller set 55 is arranged above the first material storage mechanism 53, the feeding roller set 55 comprises at least two feeding rollers capable of actively rotating, and the composite fibers sequentially bypass the at least two feeding rollers during conveying;

and the material guide roller 56 is arranged above the material feeding roller set 55, and the material guide roller 56 is used for guiding the composite fiber output after the twisting device 4 is twisted into the material feeding roller set 55.

In summary, as can be seen from fig. 7 to 11, the winding principle of the composite fiber after the forming by the integral winding device 5 is as follows:

s1, referring to the state shown in FIG. 7, the whole manufacturing equipment is shown in a normal operation state, and in the state, the winding roller 52 rotates anticlockwise in the figure, so that the composite fibers are wound at a constant speed;

s2, when the composite fibers on the winding roller 52 are wound to a preset length, the first material storage mechanism 53, the material cutting assembly 51 and the second material storage mechanism 54 are synchronously started. Wherein:

with respect to the blanking assembly 51, it includes a fixed portion and a moving portion which are arranged laterally, and the composite fibers pass through a region between the fixed portion and the moving portion while being conveyed vertically downward;

As can be seen from fig. 8 to 9: after the first storage mechanism 53 is started, the corresponding movable roller is pushed to move towards the left side in the figure, so that storage is realized (the composite fibers conveyed by the feeding roller group 55 are stored on the first storage mechanism 53, so that the composite fibers in the process cannot be conveyed to the blanking assembly 51, namely, no feeding is carried out on the blanking assembly 51); after the second material storage mechanism 54 is started, the corresponding movable roller is pushed to move towards the right side in the figure, so that discharging is realized (the winding roller 52 winds the composite fibers discharged by the second material storage mechanism 54, namely the blanking assembly 51 does not discharge); after the cutting assembly 51 is activated, the moving part approaches the fixed part to perform the cutting of the composite fiber.

In conclusion, based on the cooperation of the first storing mechanism 53 and the second storing mechanism 54, the composite fibers can be effectively kept in a static state at the blanking assembly 51 until the blanking assembly 51 finishes cutting the composite fibers.

S3, after the second material storage mechanism 54 finishes discharging, a state shown in FIG. 10 is formed, the wind-up roll 52, the first material storage mechanism 53 and the second material storage mechanism 54 are stopped in the state, and the moving back reset of the moving part in the material cutting assembly 51 is executed; meanwhile, the take-up roll 52 is replaced, and the composite fibers are conveyed vertically downwards under the guiding of the feeding roll set 55, the first storage mechanism 53 and the fixed part of the cutting assembly 51.

S4, completing replacement of the winding roller 52, fixing the end part of the composite fiber on the winding roller 52 when the composite fiber is vertically conveyed downwards to one side of the winding roller 52, and then synchronously starting the winding roller 52, the first material storage mechanism 53 and the second material storage mechanism 54. Wherein, the wind-up roll 52 can preferably use a negative suction roll, so that the fixation between the composite fiber end and the wind-up roll 52 can be automatically completed; in addition, as can be seen from FIG. 11: the wind-up roller 52 winds up in a counterclockwise rotation; the first material storage mechanism 53 moves to the right side in the figure to perform material storage; the second stocker mechanism 54 moves to the left in the figure, and performs the stocker operation until the entire structure is restored to the state shown in fig. 7.

Above-mentioned, at whole ration rolling in-process, based on first storage mechanism 53 and second storage mechanism 54's cooperation, can also effectively guarantee the uniform velocity of wind-up roll 52 rolling to appear the too big or undersize problem of tensile force when avoiding the composite fiber rolling, and need not to carry out the shut down of whole equipment, thereby effectively guaranteed the continuity and the high efficiency of composite fiber preparation.

Preferably, the fixing part of the above-described blanking assembly 51 includes two fixing rolls 511 sequentially arranged in the longitudinal direction, and the composite fibers are in contact with the fixing rolls 511 while being conveyed vertically downward.

In summary, as shown in fig. 8, the movable press roll 512 is engaged with the fixed press roll 511 (the cutter 513 does not contact the composite fibers), so that the composite fibers can be effectively compressed on both sides of the cutter 513, thereby improving the stability during cutting.

In summary, fig. 9 shows a state where the cutter 513 cuts the conjugate fiber.

The driving principle for the moving part of the above-mentioned blanking assembly 51 is: when cutting, a moving driving mechanism 514 (e.g. a hydraulic cylinder) is started, so as to drive the moving compression roller 512 and the cutting knife 513 to be close to the fixed compression roller 511, when the moving compression roller 512 is pressed against the fixed compression roller 511, the moving compression roller 512 is limited, and the cutting knife 513 is continuously close to the fixed compression roller 511 to compress the limiting spring 517 and press the clamping block 518 and the clamping spring 519 to the two sides, so that the cutting knife 513 can smoothly pass through the through hole to cut the composite fiber.
