Abstract

The invention discloses a shearing device which comprises a round cutter and a flat cutter matched with each other, wherein the round cutter comprises a round cutter roller body; two ends of the round cutter roller body are respectively provided with an end flange; a plurality of spiral cutter stripes are arranged on the round cutter roller body along the circumference direction; two ends of the spiral cutter stripes are connected with the end flanges; the roller surface of the round cutter roller body is sleeved with at least three permanent magnet rings; a spacer bush is arranged between two adjacent permanent magnet rings; a spacer bush is also arranged between each end flange and the corresponding permanent magnet ring. According to the shearing device, the round cutter roller body is sleeved with a plurality of permanent magnet rings, and magnetic force generated by the permanent magnet rings can be used for eliminating the deflection generated by the round cutter roller body to the largest extent, so that the round cutter and the flat cutter can fit uniformly, the shearing quality is greatly improved, the production manufacture period is shortened, the production cost is reduced, and the manufacture cost of the round cutter roller body is reduced simultaneously.

Description

Sheep shearing unit

Technical field

The present invention relates to the sheep shearing unit in a kind of printing in textiles device, particularly a kind of sheep shearing unit that prevents the distortion of dise knife roll body.

Background technology

Existing shearing machine, due to the weight of dise knife roll body self, machining accuracy and when the spindle nose of cylinder-pressing dise knife two ends, easily cause the flexural deformation of dise knife roll body, dise knife and flat cutter axially can not be fitted fully at roll surface, easily folder hair in shear history, occurs, cut constantly, hair side is unclear, the phenomenons such as out-of-flatness, thus the quality of production and efficiency affected.In prior art for make dise knife and flat cutter roll surface axially fully the laminating, often adopt more high-precision processing technology to guarantee that dise knife roll surface total run-out tolerance is not more than 0.02mm, not only increase processing charges, also extended the workpiece process-cycle, brought inconvenience to production.The defects such as the employing that also has increases the degree of depth that contacts of dise knife and flat cutter, easily like this causes the sharpening time long, and flat cutter quick abrasion, service life are short.

Summary of the invention

Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of reasonable in design, effectively prevents the sheep shearing unit of dise knife roll body distortion.

Technical problem to be solved by this invention is to realize by following technical scheme, the present invention is a kind of sheep shearing unit, comprise the dise knife peace cutter cooperatively interacted, described flat cutter is contained on flat knife rest, described dise knife comprises the dise knife roll body, the two ends of dise knife roll body are equipped with end flanges, on the dise knife roll body, be provided with some along its spiral tool section circumferentially be evenly arranged, two ends and the end flanges of spiral tool section are joined, be characterized in: on the roll surface of dise knife roll body, be arranged with at least 3 permanent-magnetic clamps, between two adjacent permanent-magnetic clamps and be equipped with spacer between end flanges and permanent-magnetic clamp, when the spindle nose of cylinder-pressing dise knife two ends, under the effect of dise knife roll body self gravitation, produce deflection deformation, dise knife and flat cutter are evenly fitted and eliminate the distortion of dise knife roll body.

Technical problem to be solved by this invention can also further realize by following technical scheme, and described permanent-magnetic clamp is provided with 3, uniformly the dise knife roll body is divided into to quarter.

Compared with prior art, the present invention is by being set with several permanent-magnetic clamps on the dise knife roll body, the magnetic force that permanent-magnetic clamp produces is eliminated the amount of deflection that the dise knife roll body produces to greatest extent, dise knife and flat cutter are evenly fitted, thereby significantly improve shearing quality, reduce manufacturing cycle, reduce production costs, also reduced the cost of manufacture of dise knife roll body simultaneously.

The accompanying drawing explanation

Fig. 1 is the structural representation of dise knife.

Fig. 2 is the B-B view of Fig. 1.

Fig. 3 is invention distressed structure schematic diagram.

The specific embodiment

Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.

With reference to accompanying drawing 1, Fig. 2 and Fig. 3, a kind of sheep shearing unit, comprise the dise knife peace cutter 6 cooperatively interacted, described flat cutter 6 is contained on 6, flat cutter, described dise knife comprises dise knife roll body 1, the two ends of dise knife roll body 1 are equipped with end flanges 4, on dise knife roll body 1, be provided with some along its spiral tool section 5 circumferentially be evenly arranged, the two ends of spiral tool section 5 and end flanges 4 are joined, on the roll surface of dise knife roll body 1, be arranged with at least 3 permanent-magnetic clamps 2, uniformly dise knife roll body 1 be divided into to quarter when permanent-magnetic clamp 2 is 3.Between two adjacent permanent-magnetic clamps 2 and between end flanges 4 and permanent-magnetic clamp 2, be equipped with spacer 3.During assembling, after permanent-magnetic clamp 2 installs, then end flanges 4 use screws in two ends are connected with dise knife roll body 1 end face with bearing pin, permanent-magnetic clamp 2, spacer 3 are tightly clipped in the roll surface direction, close to be ground to after size spiral tool section 5 and fastening the putting in place of end flanges 4 are got final product.

When the spindle nose of cylinder-pressing dise knife two ends, under the 1 self gravitation effect of dise knife roll body, produce deflection deformation, when deflection deformation occurs in dise knife roll body 1, its middle part can be away from flat cutter 6, because flat cutter 6 can not deform and intensity is enough, by flat cutter 6, attract permanent-magnetic clamp 2, under the magneticaction of permanent-magnetic clamp 2, can eliminate to greatest extent the amount of deflection that dise knife roll body 1 produces, dise knife and flat cutter 6 are evenly fitted, thereby eliminate 1 distortion of dise knife roll body.When the two ends spindle nose is subjected to 3000N pressure, can eliminates deflection and reach 0.05mm.

Claims

1. sheep shearing unit, comprise the dise knife peace cutter cooperatively interacted, described flat cutter is contained on flat knife rest, described dise knife comprises the dise knife roll body, the two ends of dise knife roll body are equipped with end flanges, on the dise knife roll body, be provided with some along its spiral tool section circumferentially be evenly arranged, two ends and the end flanges of spiral tool section are joined, it is characterized in that: on the roll surface of dise knife roll body, be arranged with at least 3 permanent-magnetic clamps, between two adjacent permanent-magnetic clamps and be equipped with spacer between end flanges and permanent-magnetic clamp, when the spindle nose of cylinder-pressing dise knife two ends, under the effect of dise knife roll body self gravitation, produce deflection deformation, dise knife and flat cutter are evenly fitted and eliminate the distortion of dise knife roll body.
