Abstract
The utility model discloses a navel of a rotating cup spinning machine, which belongs to a steel navel provided with notch grooves. The navel comprises a navel body, a center hole and the notch grooves, wherein the center hole passes through the navel body, and the notch grooves are arranged on the navel body. The utility model is characterized in that grooves are arranged on the wall of the center hole of the navel body. Because the utility model installs the grooves on the wall of the center hole of the navel body, during the spinning, the grooves enhance the friction effect on the outer side of the yarns, the external hair feather of the yarns is lengthened and increased, and the problems that when the existing navel has few grooves, the hair feather can not reach the long and rich requirements, and when the existing navel has many grooves, the yarn intensity is insufficient can be solved. The utility model can meet the special requirements of low twisting degree and long and rich hair feather of special yarns. In addition, the utility model also increases number of the varieties of the navels, so the range of applicable spinning raw materials and the varieties can be wider, and the utility model has the practical value.
Description
Technical field
The utility model relates to a kind of navel of rotor spinning machine, belongs to the spinning machinery equipment technical field.
Background technology
At present, under the revolving cup high-speed condition, the main task of the navel of rotor spinning machine is to be lowered into twist per unit, improves spinning stability.Particularly, strengthen the brute force of sliver between yarn in the revolving cup collection surface and the navel exactly, thereby reduce and prevent the sliver broken end, this intersegmental twisting effect is false twisting.In order to strengthen the false twisting effect, concrete measure is to improve material and surperficial enhancement process, thereby the navel series of products occurred, as: the steel navel that ceramic navel, surface hardening are handled.Can select different navel cambered surface radius and aperture for use according to rotor speed, spinning suiting kind difference.Be to strengthen the false twisting effect simultaneously on ceramic navel, steel navel, increased cutting again, series of products such as three-flute, four grooves, six grooves, eight grooves, 16 grooves are arranged respectively.In addition, ceramic navel also has the surface to have the kind of screw line pattern.Though these navels are owing to material difference, cambered surface radius difference, aperture difference, groove are counted difference, also can partly satisfy conventional rotor spinning demand, but for requiring the special yarn that the twist is low, filoplume is long and plentiful, if with existing eight groove navels, filoplume does not reach long and plentiful requirement; If with existing 16 groove navels, though the requirement of filoplume has reached yarn strength deficiency, end breakage rate height.Therefore, existing navel can not satisfy the specific (special) requirements of special yarn " twist is low, filoplume is long and plentiful ".
The utility model content
The purpose of this utility model provides a kind of navel of rotor spinning machine, with the specific (special) requirements of " twist is low, filoplume is long and plentiful " of satisfying special yarn.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The navel of rotor spinning machine provided by the utility model, for being provided with the steel navel of cutting, comprise the navel body, connect the centre bore of navel body and be located at cutting on the navel body, it is characterized in that: on the hole wall of the center of navel body, be provided with groove.
The center line of each groove is adjacent preferred 0 °～120 ° of the angle of cutting center line.
The shape of described groove can be any geometric form, geometric form with rules such as V-arrangement, U-shaped, rectangles is preferable, especially with V-arrangement the best, the preferred extended distance of v-depression is that the arc radius of 0.4～3.5mm, bottom is that the outside diameter that 0.1～2mm, v-depression form is 2.1～5.5mm.
Preferred 1～5 of the number of described groove.
The cambered surface radius on top, described navel preferred center hole is that the diameter of 4～10mm, centre bore is 2～3.5mm.
Preferred 3～the 18mm of top distance of preferred 3～32 of the cutting number on the navel body, relative two cuttings.
Compared with prior art, the utlity model has following beneficial effect:
1) because the utility model is provided with groove on the hole wall of the center of navel body, when spinning, groove to the yarn external reinforcing rubbing action, thereby make its outside filoplume increase, increase, so that solved that the few and filoplume of the existing groove number of existing navel does not reach long and plentiful requirement, the groove number is many and the contradiction of yarn strength deficiency can satisfy the specific (special) requirements of " twist is low, filoplume is long and plentiful " of special yarn.
2) the utility model has increased navel kind number, and it is wider to make it spinning suiting raw material and variety range, has practical value.

Fig. 1 is the plan structure schematic diagram of navel provided by the utility model;
Fig. 2 is the cross-sectional view of navel provided by the utility model.
Among the figure: 1, navel body; 2, centre bore; 3, cutting; 4, groove.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further in detail, is illustrated clearly and completely:
Embodiment
As depicted in figs. 1 and 2: the navel of the rotor spinning machine that present embodiment provided, for being provided with the steel navel of cutting, comprise navel body 1, connect the centre bore 2 of navel body and be located at cutting 3 on the navel body, it is characterized in that: on the hole wall of the center of navel body, be provided with groove 4.
The center line of each groove is adjacent the angle α of cutting center line, can carry out preferably according to not coexisting 0 °～120 ° of spinning suiting raw material, spinning suiting kind.
The shape of groove 4 can be any geometric form, and is preferable with the geometric form of rules such as V-arrangement, U-shaped, rectangle, especially with V-arrangement the best; For v-depression, preferred extended distance L1 is 0.4～3.5mm, and bottom arc radius R1 is 0.1～2mm, and the outside diameter d1 that v-depression forms is 2.1～5.5mm, can carry out the preferred compositions of above-mentioned parameter according to the difference of spinning suiting raw material, spinning suiting kind.
The number of groove 4 can be preferably 1～5 according to the difference of spinning suiting raw material, spinning suiting kind, if be provided with two or more grooves, its shape can be identical, also can adopt difform combination to reach optimum efficiency, and two or more groove can become circumference evenly to distribute or uneven distribution along the axis of centre bore.
The diameter d 2 that the described cambered surface radius R2 that is provided with the top, steel navel preferred center hole of cutting is 4～10mm, centre bore is that 2～3.5mm, cutting number are that 3～32, the top distance of relatively cutting are 3～18mm, the preferred compositions that can carry out above-mentioned parameter according to the raw material and the kind difference of spinning suiting.
