The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of fibre cutting machine hold-down mechanism, comprise: support 1, supporting plate 2, contact roller 3, support wheel 4, guide plate 5, contact roller cutting knife 6, support wheel cutting knife 7, driving shaft 8, driven shaft 9, axle sleeve, driving wheel 10 and suction port 11, described support 1 is provided with supporting plate 2, supporting plate 2 front ends are provided with support wheel 4, described support wheel 4 tops are provided with contact roller 3, guide plate 5 is arranged on supporting plate 2 tops, both sides, described driving shaft 8 is arranged in contact roller 3, described driven shaft 9 is arranged in support wheel 4, contact roller cutting knife 6 is arranged on driving shaft 8, after contact roller cutting knife 6, be provided with axle sleeve, driving wheel 10 is arranged on driving shaft 8 ends, described support wheel 4 cutting knifes are arranged on driven shaft 9, guide plate 5 arranged outside have suction port 11.
Described contact roller 3 and support wheel 4 outsides scribble frictional layer, and described contact roller 3 both sides are provided with contact roller cutting knife 6, and described support wheel 4 both sides are provided with support wheel cutting knife 7.
Described guide plate 5 is arranged on support both sides, and described guide plate 5 is provided with 2, and guide plate 5 front end upsides are provided with arc incision, and described arc incision is 1/4 circle, can fit with contact roller 3 preferably, reduces the probability that fiber is involved in driving shaft.
Described contact roller cutting knife 6 edges are provided with cutting edge, and described support wheel cutting knife 7 sides, edge are provided with the cutting knife groove that can coordinate with the cutting edge of described compression cutting knife 6, can effectively cut off the fiber that is about to be involved in and avoid being wound around, and guarantee that machine operates steadily.
Described supporting plate 2 upper surfaces and support wheel 4 peaks, in same plane, carry steadily fibrous raw material, avoid fiber to be involved in driving shaft.
Described support 1 is provided with height adjuster and spring, and described spring is arranged on driving shaft 8 tops, improves hold-down mechanism adaptability, improves operating efficiency and the adaptive capacity of fibre cutting machine.
Described guide plate 5 interplanars form an angle, and described angle is 20 degree, and described guide plate 5 spacing are restrained to contact roller 3 gradually by rear end, avoid fiber to external diffusion, reduce and are wound around possibility.
The beneficial effect of fibre cutting machine hold-down mechanism of the present invention is:
One, the fibrous material that adapts to different-thickness by guiding mechanism is set,
Two, by contact roller and support roller, cutting knife being set, guarantee that outwards mobile fiber can be cut off, avoid being entangled to machine, impact is used;
Three, by shaping-orientation plate, axle sleeve and suction port, avoided Filament-wound Machine to axle;
Four, compare existing design, the present invention has the advantages such as unfailing performance is high, registration, compact conformation, transposition speed is fast, noise is little, cheap, simultaneously the application of miniature numerical control lathe and universal on have market prospects widely.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
