Abstract

The utility model discloses a knife roller of a fiber cutter, comprising a roller shaft and a knife blade, wherein the outer surface of the roller shaft is provided with an axial knife groove; the knife blade is arranged in the axial knife groove in a mode that the cutting edge faces outwards, and the cutting edge protrudes out of the outer surface of the roller shaft; and two ends of the roller shaft are provided with end covers for pressing and fixing the roller shaft and the knife blade, and the groove width of the axial knife groove is greater than the thickness of the knife blade. The utility model changes the structure that the knife blade of the conventional knife roller is closely embedded into the knife groove, and is provided with the axial knife groove with the groove width greater than the thickness of the knife blade; the knife blade can vibrate with high frequency when the knife roller is in rotating operation as the knife blade is not clamped by the axial knife groove, high frequency vibration can shake out cut-off fibers so that fibers are not attached to the knife roller and the knife blade keeps sharp state all the time and does not need frequent stopping for cleaning, thereby improving the production efficiency and simultaneously having stable quality of products.

Description

Fiber chopping machine rotor

Technical field

The utility model relates to a kind of fiber chopping machine parts, is specifically related to a kind of fiber chopping machine rotor.

Background technology

Along with The development in society and economy, fibres such as increasing textile waste, chemical fibre, waste and old clothing, leather become house refuse, because the deep development of conservation-minded society need be regenerated to produce and be utilized these fibres.

The characteristics of textile fabric based article are that hardness is not high, but structure of fibrous tissue interweaves closely, the TENSILE STRENGTH height, are difficult for disconnecting, easily twining, and shape is fixing, wants this type of material is carried out fragmentation, cut off that to handle be a very very difficult thing.Present known fiber chopping machine has punching cutting type chopping machine and rotates cutting type chopping machine etc.; So the reciprocating motion of punching cutting type chopping machine cutter is owing to exist idle stroke efficient not high; And rotation cutting type chopping machine adopts the cut staple that relatively rotates of rotor and rubber roll; its defective is: after fibre cutting; the fiber that part is cut off can not come off automatically; between adjacent edge and rubber roll grooving place can sandwich the fiber of cut-out; cause when continuing chopping blade to cross shallow and can't cut off follow-up fiber; even cause winding or produce broken silk; also can aggravate the blade wearing and tearing simultaneously; cause unstable product quality; general existing chopping machine running was less than one hour; just can only shut down cleaning, have a strong impact on production efficiency.

Summary of the invention

In view of this, the purpose of this utility model is to provide a kind of fiber chopping machine rotor, and the fiber of cut-out is come off automatically, non-cohesive fiber on the rotor, and blade remains sharp state, need not the frequent shutdown cleaning, enhances productivity.

Fiber chopping machine rotor of the present utility model, comprise roll shaft and blade, described roll shaft outer surface has the axial cutters groove, described blade is inserted in the axial cutters groove in the outside mode of cutting edge and cutting edge protrudes the roll shaft outer surface, the roll shaft two ends are provided with the end cap that is used to be fixed roll shaft and blade, and the groove width of described axial cutters groove is greater than the thickness of blade.

Further, described axial cutters groove radially extends at the cross section upper edge roll shaft perpendicular to the roll shaft axis;

Further, described axial cutters groove is evenly distributed along the roll shaft circumferencial direction.

The beneficial effects of the utility model are: the blade that the utility model has changed existing rotor closely embeds the structure in the cutter groove; the axial cutters groove of groove width greater than blade thickness is set; because blade do not clamp by the axial cutters groove, so rotor is when rotating operation, and blade can high-frequency vibration; high-frequency vibration shakes the fiber of cut-out; make non-cohesive fiber on the rotor, blade remains sharp state, need not the frequent shutdown cleaning; improved production efficiency, product quality is highly stable simultaneously.

Description of drawings

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic;

Fig. 3 is the B place enlarged drawing of Fig. 2.

The specific embodiment

Fig. 1 is a structural representation of the present utility model, Fig. 2 be the A-A of Fig. 1 to cross-sectional schematic, Fig. 3 is the B place enlarged drawing of Fig. 2; As shown in the figure, fiber chopping machine rotor of the present utility model, comprise roll shaft 1 and blade 2, described roll shaft 1 outer surface has axial cutters groove 3, described blade 2 is inserted in the axial cutters groove 3 in the outside mode of cutting edge and cutting edge protrudes roll shaft 1 outer surface, roll shaft 1 two ends are provided with the end cap 4 that is used to be fixed roll shaft 1 and blade 2, and the groove width of described axial cutters groove 3 is greater than the thickness of blade 2.

As further improvement of the utility model, described axial cutters groove 3 radially extends at the cross section upper edge roll shaft 1 perpendicular to roll shaft 1 axis; Make blade 2 on cross section, be radial arrangement, cut off the efficient height, prevent to twine perpendicular to roll shaft 1 axis.

As further improvement of the utility model, described axial cutters groove 3 is evenly distributed along roll shaft 1 circumferencial direction; Distance between blade 2 cutting edges promptly is required shearing length, and described axial cutters groove 3 is evenly distributed along roll shaft 1 circumferencial direction, makes the distance between blade 2 cutting edges even, and shearing length does not have difference, and it is higher to cut off precision.

Fiber chopping machine rotor of the present utility model is installed on the fiber chopping machine; during chopping work; rotor is high speed rotating under the drive of transmission device; because the groove width of axial cutters groove 3 is greater than the thickness of blade 2; blade 2 is not clamped by axial cutters groove 3; therefore blade 2 meeting high-frequency vibrations (vibration frequency preferably remains on more than the 1000HZ); high-frequency vibration shakes the fiber of cut-out; make non-cohesive fiber on the rotor; blade remains sharp state; need not the frequent shutdown cleaning, improved production efficiency, product quality is highly stable simultaneously.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
