Abstract
The utility model relates to rolling-proof doffer metallic card cloth, which is provided with a bar-shaped body, and the upper part of the body is provided with jagged teeth. Compared with the prior art, the utility model is characterized in that the jagged teeth form a tooth shape with laigh and big gradient, and the side with a slant angle of teeth is a fold line transitional surface. The utility model has the advantages that the intensity and the rigidity of the utility model can be raised, and the utility model can enhance rolling-proof performance and has long service life.
Description
The utility model relates to cotton, wool spinning equipment, is the parts on a kind of cotton, the wool spinning equipment, the rolling-proof of using on specifically a kind of cotton, the wool spinning equipment carding machine.
Rolling-proof is the important spare part on the carding machine, existing rolling-proof metal needle is furnished with a bar shaped main body, main body top is serrated teeth, it is more elongated that tooth seems, its top is flat, the side of tooth is a complete inclined-plane, and such structure makes that its strong rigidity is relatively poor, and service life is shorter.
Technical solution of the present utility model is: a kind of rolling-proof metallic card clothing, a bar shaped main body is arranged, main body top is serrated teeth, and the difference of itself and prior art is: serrated teeth adopts short big gradient profile of tooth, and the broken line transition face is adopted in a band side, inclination angle of tooth.
The main body height overall at the short big gradient tooth place described in the utility model is 3.5-4MM; Backlash is 1.5-1.9MM.Certainly, also can adopt other suitable height, gap size or other suitable version.
Tooth top described in the utility model is cut sth. askew into 10-30 ° of angle; Clearance angle is 35-44 °.Certainly, also can adopt other suitable angles of inclination or other suitable version.As adopt tooth top to cut sth. askew into 18-22 ° of angle; Clearance angle is the 38-42 ° of angle numerical value that grade is better.
Advantage in the utility model is: its strong rigidity is improved greatly, and the anti-performance of rolling strengthens long service life.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of a kind of rolling-proof metallic card clothing of the present utility model;
Fig. 2 is the right view of Fig. 1.
Fig. 1, Fig. 2 have described an embodiment of the present utility model jointly.In this embodiment, a bar shaped main body 1 is arranged, main body 1 top is serrated teeth 2, and serrated teeth 2 adopts short big gradient profile of tooth, and the broken line transition face is adopted in a band side, inclination angle of tooth.Main body 1 height overall at short big gradient tooth place is 3.8MM (or other suitable height numbers); Backlash only is 1.7MM (or other suitable numerical value), and tooth top is cut sth. askew into 20 ° of angles (or 10-30 ° and even 18-22 ° wait other suitable angle values); Clearance angle be 40 ° (or 35-44 ° so more specifically 38-42 ° wait other suitable angle values), but with tooth top cut sth. askew into 20 °, Clearance angle be 40 ° for preferable, aforementioned angle Selection had both guaranteed that crown was sharp, had increased tooth top length again; Flank adopts double inclined plane, has strengthened tooth root intensity, makes the utility model profile of tooth short and stout, and strong rigidity improves greatly.Adopt the 72B steel to replace original 57B, steel strength improves, and the crown quenching hardness improves, and is both wear-resisting because the utility model has adopted above-mentioned corrective measure, anti-again rolling.No matter spin chemical fibre or cotton, hair, spinning performance is good, and the anti-ability of running over and injure improves greatly, service life significant prolongation.
