Abstract
The utility model discloses a kind of polyimide fiber special-purpose metal pin cloth, comprises pin tooth and Ji Bu, and the operating angle α of pin tooth is 90 ° ~ 93 °.The utility model improves the transfer ability of fiber on pin tooth, effectively can solve the winding needle cloth phenomenon in polyimide fiber carding process, and pin waring of cloth is good, intensity is high, long service life.
Description
Technical field
The utility model belongs to spinning equipments technical field, relates to a kind of pin cloth, relates to a kind of polyimide fiber special-purpose metal pin cloth.
Background technology
The coating that surface distributed the various carding machine cylinders of needle point is referred to as pin cloth, and it uses the history of existing more than 200 year.Pin cloth is widely used on the spinning machinery such as carding machine, combing machine, be coated on roller or the combing plate surface of the combing elements such as carding machine licker-in, cylinder, doffer, cover plate, combing plate or combing machine circle comb, played the effects such as crawl, shredding, removal of impurities, transfer and cohesion by carded fiber.Whether pin cloth is selected supporting appropriate, is the key ensureing carding machine cards quality, as mis-arrange, no matter how excellent each parts of carding machine, measure and technique is, also can not obtain satisfied carding quality and excellent product.Pin cloth select supporting must consider processed fiber character, carding machine technique, the requirement of spinning conditions, complementing one another and influencing each other between specifications parameter between cylinder and doffer and flat-clothing.
Polyimide fiber has the premium properties such as high strength mould, high temperature resistant, radiation hardness, can be woven into rope, woven into fabric or make nonwoven fabric, being used in the filtration of high temperature, radioactivity or organic gas or liquid, fire insulation felt, fire protection flame retarding clothes etc.When polyimide fiber with carding machine cards length comparatively cotton fiber long (generally in length at 32mm ~ 40mm), because increasing with the contact area of pin cloth in its carding process, friction increases, electrostatic charge sharply increases, cause serious winding needle cloth in carding process, greatly affect spinning quality, and due to polyimide fiber intensity high, the serious wear of pin cloth.This will rely on the design improving card clothing specification parameter, improves pin cloth workmanship (as roughness, flatness etc.) and improves carding machine technique and solve.
Can cardability for what improve polyimide fiber, the operating angle of pin cloth, the intensity improving crown and ABRASION RESISTANCE can be increased.The operating angle of existing pin cloth is less than 90 ° usually, and the thickness of crown is generally at 0.15 ~ 0.2mm.The operating angle improving pin cloth can improve the transfer ability of fiber on pin tooth, but can reduce carding effect, and the thickness of pin tooth can affect ABRASION RESISTANCE and the intensity of crown, the too thick sharpness that can affect tooth bar.
Utility model content
The utility model is to overcome in above-mentioned polyimide fiber carding process the special-purpose metal pin cloth that existing problem designs.The utility model provides a kind of pin cloth, particularly a kind of polyimide fiber special-purpose metal pin cloth.
A kind of polyimide fiber special-purpose metal pin cloth of the present utility model, comprise pin tooth and Ji Bu, described pin tooth is embedded on described base cloth, and the operating angle of described pin tooth is 90 ° ~ 93 °.The pin tooth operating angle of existing pin cloth is generally less than 90 °, when the operating angle of pin tooth increases, be conducive to the transfer of fiber on pin tooth, but operating angle is crossed conference and is reduced pin tooth to the combing effect of fiber, due to polyimide fiber very easily winding needle cloth, the operating angle of pin tooth is changed into 90 ° ~ 93 °, effectively can avoid the generation of cast-over cloth phenomenon, also can ensure its carding effect simultaneously.
As preferred technical scheme:
A kind of polyimide fiber special-purpose metal pin cloth as above, the crown height of described pin tooth is between 0.35 ~ 0.5mm, and total tooth depth of described pin tooth is between 1.5 ~ 1.8mm.The feature of present carding machine development is high yield, at a high speed, pin tooth also form the feature of short tooth, shallow tooth, and crown height is little, fiber can be made to be in crown tip, be not easy to around cylinder, and total tooth depth reduces, and improves that crown is anti-rolls intensity.
A kind of polyimide fiber special-purpose metal pin cloth as above, the tooth pitch between described pin tooth is between 4 ~ 5.5mm.When spinning chemical fibre, the tooth pitch grasp bigger than normal of pin tooth, is conducive to the ABRASION RESISTANCE strengthening pin tooth.
A kind of polyimide fiber special-purpose metal pin cloth as above, the tooth angle of described pin tooth is 50 ° ~ 70 °.Tooth angle affects intensity and the ABRASION RESISTANCE of crown, because polyimide fiber intensity is high, so should grasp bigger than normal.
A kind of polyimide fiber special-purpose metal pin cloth as above, the size of the crown width of described pin tooth is 0.12 ~ 0.15mm.In order to improve the ABRASION RESISTANCE of crown, there is a very little plane on crown top, but this plane is unsuitable excessive, otherwise can reduce the sharpness of tooth bar.
A kind of polyimide fiber special-purpose metal pin cloth as above, the crown thickness of described pin tooth is 0.18 ~ 0.2mm.In order to improve intensity and the ABRASION RESISTANCE of crown, crown will have certain thickness, and when spinning polyimides, the thickness of crown should be bigger than normal, but should not be too large, otherwise can affect the sharpness of tooth bar and the decomposition to fiber.
A kind of polyimide fiber special-purpose metal pin cloth as above, the back of tooth of described pin tooth is arc, and maximum tooth dorsal horn is 70 °.The back of tooth of pin tooth is the intensity that arc can improve pin tooth.
Beneficial effect
Compared with prior art, a kind of polyimide fiber special-purpose metal pin cloth of the present utility model has the following advantages:
1. a kind of polyimide fiber special-purpose metal pin cloth operating angle of the present utility model is comparatively large, effectively can solve the winding needle cloth phenomenon in combing polyimides process.
2. a kind of polyimide fiber special-purpose metal pin cloth intensity of the present utility model is high, and ABRASION RESISTANCE is good, long service life.
