Abstract

Disclosed is a multi-end cutter for continuously cutting fibers. The existing cutters for continuously cutting fibers only can cut fibers by one head, and inject by compressed air without a tension mechanism or a holding mechanism. Thus the cutting of the fibers is often inoperative, for the tension and holding force of the cutter can not be controlled. The cutter frame of the multi-end cutter for continuously cutting fibers is fixed on a rotary shaft in a detachable mode so as to change the cutting length of the fibers by changing the separation distance of the cutter frame. The method for fixing a spring bolt slide block is used to fix a tension roller and a knife padding roller, and thus the fibers are inputted automatically for cutting with a certain tension. The pressures of the tension roller and the knife padding roller both can be regulated randomly (by the pressure of the spring slide block), and thus the fibers can be effectively cut and the service life of cutter blades is prolonged.

Description

Cutter for multi-end continuous fiber

The utility model belongs to bull continuous fibers cutting machine.

Existing continuous fibers cutting machine, can only carry out the cutting of single head fiber, fiber after being cut is gone out by blast injection, for Cutting Length that changes fiber and replacing blade, because of its complex structure, and extremely inconvenient, and the tension force of fiber is uncontrollable and clamp method can't solve.

The purpose of this utility model is that the bull continuous fibers is cut, and guarantees that fiber by firm clamping and the certain tension force of generation, effectively carries out cutting, and can prolong the life-span of blade.

When the utility model bull continuous fibers cuts, the bull continuous fibers is by jockey pulley and pad rotor clamping and guarantee that continuous fibers sends constantly into the edge of a knife and produce certain tension force, can adjust the spring press force in addition, control tension force size, the bull continuous fibers is in cutting process, and can control the pressure that fills up between rotor and the blade by the slip of spring, and both guaranteed that fiber effectively cut, can prolong the service life of blade again.

Fig. 1 is the structure chart of bull continuous fibers cutting machine.

Fig. 2 is the profile of bull continuous fibers cutting machine.

The utility model is implemented as follows:

With reference to Fig. 1, Fig. 2, the utility model has the rotating shaft (1) of a fixed blade, rotating shaft (1) is gone up the knife rest (2) that setting can change blade distance, pad rotor (3) is by knife rest (2) spin friction transmission, pressure between pad rotor (3) and the knife rest (2) is controlled by spring (4) pressed slider (5), pressure between jockey pulley (6) and the pad rotor (3) is controlled by spring (4) pressed slider (5), pressure between jockey pulley (6) and the pad rotor (3) is also controlled by spring (7) pressed slider (8), the continuous fibers that is cut is by between jockey pulley (6) and pad rotor (3), makes continuous fibers send constantly into blade and fill up between the rotor (3) to be cut off owing to fill up be fixed knife rest (2) the spin friction transmission of blade of rotor (3).By adjusting the distribution of knife rest (2) top blade, obtain different spacings, come the Cutting Length of controlling fiber.Because the pressure between pad rotor (3) and the blade is next self-regulating by spring block (8), so can prolong the service life of blade.

The utility model is compared with original technology, and it is complete to have function, both can cut single head, also can cut multi-end continuous fiber, also can cut random fiber, it is convenient to change Cutting Length, continuous fiber is sent into automatically, and has some tension and chucking power, thereby guarantees effective output and the cutting of fiber. The utility model all can cut organic and inorfil.

Claims

1, a kind of bull continuous fibers (organic and inorfil) cutting machine, form by rotating shaft (1), knife rest (2), pad rotor (3), jockey pulley (4) and adjustable spring slide block (5), (6), (7), (8), it is characterized in that knife rest (2) can move according to fiber length is provided with, so the big I of pressure is adjusted at random automatically.
