Description

Half arc tooth top metallic card clothing of one kind rushes tooth device

Technical field

The utility model relates to a kind of carding element manufacture fields of textile machine, and in particular to half arc tooth top gold of one kind Belong to needle cloth and rushes tooth device.

Background technique

Carding element is the core equipment in spinning processing, and metallic card clothing is most important element on carding element again.With Textile raw material, fabric property difference, especially all kinds of tencels, which are widely applied, proposes more the use of metallic card clothing High requirement, the quality of metallic card clothing are mainly reflected on finish, sharpness, wear resistance, flatness and uniform quenching degree.So And the product structure that metal card clothing teeth punching machine tool is produced at present also occurs recently substantially based on pointed tooth type Rib type tooth and major-minor toothing metallic card clothing, but the flute profile of existing metallic card clothing belongs to direct tooth type, and direct tooth type metallic card clothing is deposited In following disadvantage: 1, fiber stream constantly passes through from needle friction between teeth so that tooth tip is gradually worn, after the sharpness decline of needle tooth So that yarn quality degradation, causes the service life of metallic card clothing to greatly shorten；2, due to the stress of metallic card clothing tooth tip The smaller i.e. anti-pressure ability of area is small and weak, so that metallic card clothing work hour hands tooth is flexible under biggish external force, falls Volt；3, direct tooth type metallic card clothing when processing and manufacturing rushes tooth because on tooth punching machine device motor and the reasons such as the needle cloth speed of service it is easy Generate size tooth, and there is metallic card clothing existing for size tooth to be coated on roller that poor flatness i.e. feel is then presented is bad.

Utility model content

The purpose of this utility model is to overcome deficiency in the prior art, provide that a kind of structure is simple, installation side Just, it can guarantee that product anti-pressure ability is strong and half arc tooth top metallic card clothing with long service life rushes tooth device.

To achieve the above object, it includes tooth punching machine that the utility model, which provides half arc tooth top metallic card clothing of one kind and rushes tooth device, Structure and Qian Liao mechanism, tooth punching machine structure are provided with cutterhead, and stamping knife is equipped on cutterhead, and the stamping knife is provided with cutter hub and fixed base Portion, fixed base are in cuboid；The cutter hub includes before knife, arc top surface, knife spine face, half curved knife root and scarf, Knife front vertical is linearly with knife spine face before fixed base, knife, is justified with knife spine face intersection by arc top surface before knife Slip, half curved knife root is arc-shaped and half curved knife root and knife spine face and fixed base are in round and smooth connection；Half arc The radian of knife root is less than 90 °.

The cutterhead is symmetrically arranged with two stamping knives.

It is 80 ° to 95 ° that the knife spine face and fixed base, which are formed by angle a, and scarf is formed by with fixed base Angle b is 30 ° to 45 °.

The height h of the cutter hub₁For 2.00mm to 6.00mm, cutter hub width w₁For 0.05mm to 1.00 mm；Half curved knife The radius r of root₁For 0.30mm to 0.80mm, the height h of fixed base₂For 10.20 mm to 12.70mm, the width of fixed base Spend w₂For 1.40mm to 2.00；The radius r of the arc top surface₂For 0.28mm.

The utility model has the beneficial effects that rush tooth apparatus structure simple for the half arc tooth top metallic card clothing of the utility model, Manufacture is easy；The half camber tooth top metallic card clothing product that serrated knife is produced of rushing on cutterhead is mounted on instead of direct tooth type metal needle Then half camber tooth top is not easy to be worn cloth, can greatly extend the service life of product；The metallic card clothing product of production has half arc Type tooth top, which significantly improves i.e. anti-pressure ability than the ability that the tooth tip of direct tooth type bears pressure, to be enhanced, therefore half camber tooth top metallic card clothing Needle tooth at work because anti-pressure ability by force without it is flexible, lodging；The needle tooth of half camber tooth top is processed because top is cambered In the presence of and avoid because of situations such as in processing equipment running speed unevenly be formed by error so that generate size tooth i.e. needle The phenomenon that tooth is uneven, while also effectively overcoming direct tooth type metallic card clothing and being coated on roller presented poor flatness i.e. The bad drawback of feel；On the one hand revolving speed that two stamping knives can be effectively reduced cutterhead, another party are symmetrically installed on cutterhead Face can preferably reduce the service life for wearing and greatly prolonging equipment.

Tooth device is rushed to the half arc tooth top metallic card clothing of the utility model with reference to the accompanying drawing to be described further.

Specific embodiment

As shown in Figure 1, Figure 2 and Figure 3, the half arc tooth top metallic card clothing of the present embodiment rush tooth device include tooth punching machine structure and Qian Liao mechanism, tooth punching machine structure are provided with cutterhead 1, and two stamping knives 2 are equipped on cutterhead 1, and stamping knife 2 is provided with cutter hub 3 and fixed base Portion 4.Fixed base 4 is in cuboid, and cutter hub 3 includes 5, arc top surface 6 before knife, knife spine face 7, half curved knife root 8 and beveling Face 11,5 perpendicular to fixed base 4 before knife, and 5 is linearly with knife spine face 7 before knife, before knife 5 with 7 intersection of knife spine face By the round and smooth connection in arc top surface 6, half curved knife root 8 is arc-shaped and half curved knife root 8 with knife spine face 7 and fixed base 4 is in Round and smooth connection；The radian of half curved knife root 8 is less than 90 °.Knife spine face 7 and fixed base 4 be formed by angle a be 80 ° extremely 95 °, it is 30 ° to 45 ° that scarf 11, which is formed by angle b with fixed base 4,.The height h of cutter hub 3₁Extremely for 2.00mm 6.00mm, 3 width w of cutter hub₁For 0.05mm to 1.00mm；The radius r of half curved knife root 8₁It is fixed for 0.30mm to 0.80mm The height h of base portion 4₂For 10.20mm to 12.70mm, the width w of fixed base 4₂For 1.40mm to 2.00；The radius of arc top surface 6 r₂For 0.28mm.Cutterhead 1 is symmetrically arranged with two stamping knives 2, can be effectively reduced the revolving speed of cutterhead, on the other hand can be preferable Reduce the service life for wearing and greatly prolonging equipment in ground.

As shown in Figures 4 and 5, half camber tooth top metallic card clothing 9 after being processed using the utility model replaces direct tooth type gold Belonging to needle cloth, then half camber tooth top 10 is wear-resisting, and service life extends；Half camber tooth top 10 of half camber tooth top metallic card clothing 9 compares straight-tooth The ability that the tooth tip of type bears pressure is significantly improved without flexible, lodging；The needle tooth of half camber tooth top 10 is when rushing tooth processing Because scarf 11 is parallel with the base portion of processed metallic card clothing always, thus effectively eliminate size tooth i.e. needle tooth and needle tooth it Between the phenomenon that being uneven.
