Description
Technical field
The utility model relates to a kind of tooth bar, relates in particular to a kind of mao of nonwoven Rack for carding machine.
Background technology
Hair nonwoven Rack for carding machine Shi Mao nonwoven enterprise carding machine core parts, its function is under tooth bar and tooth bar interact, fibre bundle obtains sufficient combing, removes impurity, dirt bits and cotton knot in fiber, and the fiber after minute comb removal of impurities is stripped, condenses, becomes net (or slivering).Existing hair nonwoven Rack for carding machine, particularly doffer and working roll tooth bar, taking side to add band, working face adds step and strengthens, in carding process, fiber is captured to control ability, reducing tooth bar does not grab fiber, falls the phenomenons such as fiber, but these methods still can not solve doffer and working roll tooth bar is grabbed the phenomenon that does not live fiber and fall fiber when running to roll body downside, thereby thoroughly solution is never grabbed fiber and the phenomenon of falling fiber, affects tooth bar carding effect.
Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The utility model provides a kind of mao of nonwoven Rack for carding machine.
The technical solution adopted in the utility model is:
A kind of mao of nonwoven Rack for carding machine, this tooth bar comprises a plurality of tooth portions and base portion, on described base portion, be longitudinally provided with continuously a plurality of tooth portion, at the bottom of each tooth portion includes tooth, tooth top, working face and the back of tooth, on the back of tooth, be at least provided with a recess, recess is located between the back of tooth section on the back of tooth, between recess and back of tooth section, has arc transition section.
The female portion is any one or two kinds and above combination of circular arc, ellipse, trapezoidal, triangle, rectangle.
The radius of curvature of described arc transition section is 0.04-0.06mm.
The degree of depth of the recess from the back of tooth to working face direction is 0.05-0.4mm, and the female portion is 0.05-0.5mm along the width of back of tooth direction.
At least one recess is located at the back of tooth first half near tooth top, and is positioned at apart from tooth top vertical range 0.1-1mm place, along first recess towards tooth at the bottom of direction, the recess vertical range between often adjacent is 0.2-1mm.
The beneficial effects of the utility model are: scientific structure design is reasonable, by the one or more recess of rear flank, strengthen tooth bar to the crawl of fiber and control ability, improve tooth bar and do not grab fiber, fall the phenomenons such as fiber, improve tooth bar carding effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of tooth portion in Fig. 1.
Wherein: 1, tooth portion, 2, base portion, 3, at the bottom of tooth, 4, tooth top, 5, working face, 6, the back of tooth, 7, recess, 8, back of tooth section, 9, arc transition section.
The specific embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, to of the present utility model, be described in further detail, this embodiment only, for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As depicted in figs. 1 and 2, a kind of mao of nonwoven Rack for carding machine of the present utility model, this tooth bar comprises a plurality of tooth portions 1 and base portion 2, on base portion 2, be longitudinally provided with continuously a plurality of tooth portion 1, each tooth portion 1 includes at the bottom of tooth 3, tooth top 4, working face 5 and the back of tooth 6, on the back of tooth 6, be at least provided with a recess 7, recess 7 is located between the back of tooth section 8 on the back of tooth 6, between recess 7 and back of tooth section 8, there is arc transition section 9, the radius of curvature of arc transition section 9 is 0.04-0.06mm, the degree of depth of the recess 7 from the back of tooth 6 to working face direction is 0.05-0.4mm, recess 7 is 0.05-0.5mm along the width of the back of tooth 6 directions, at least one recess 7 is located at the back of tooth 6 first halves near tooth top 4, and be positioned at apart from tooth top 4 vertical range 0.1-1mm places, 3 directions at the bottom of along first recess 7 towards tooth, every recess 7 vertical ranges between adjacent are 0.2-1mm,
Recess 7 is any one or two kinds and above combination of circular arc, ellipse, trapezoidal, triangle, rectangle.
The beneficial effects of the utility model are: scientific structure design is reasonable, by the one or more recess of rear flank, strengthen tooth bar to the crawl of fiber and control ability, improve tooth bar and do not grab fiber, fall the phenomenons such as fiber, improve tooth bar carding effect.
The above; it is only preferred embodiment of the present utility model; be not the utility model to be done to the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
