Technical field
The present invention relates to field of textile machinery, relate in particular to the two-for-one twister field, specifically a kind of twisting mechanism of two-for-one twister.
Background technology
Two-for-one twister is a kind of twisting equipment, can be bonded into strand to the single thread more than two strands or two strands by twisting, realizes that one changes two sth. made by twisting, and twisting efficiency significantly improves than traditional twisting apparatus.And, have package capacity and increase, the myriametre non junction, the twisting quality significantly improves, and lower floor height is particularly suitable for advantages such as operation, so is widely used in the twisting operation of the cotton textiles of fibers such as textile industry middle cotton, hair, terylene and blended yarn.
Commercially available two-for-one twister mainly is divided into two kinds of structures at present.
The category-A structure: this structure is the most traditional two-for-one twister, drag by a main motor (as asynchronous induction machine), the rotation of spindle is finished in transmission through tengential belt, finish the action of three parts such as the rotation of take up roll, the yarn-transfering rod reciprocating motion of traversing by the transmission of tengential belt and gear-box, each running part is by a plurality of gearbox drive.The two-for-one twister of this Purely mechanical must dispose a large amount of twist transformation gear and belt pulley, to satisfy the requirement of the different twist yarns of processing, not only the machine construction complexity, bulky, accessory is many, and gear-box difficulty of processing adjustment difficulty big, technique change is big and loaded down with trivial details, the running noise big, especially severe be the energy consumption height.The energy-saving and emission-reduction that this and China advocate require incompatible.The great number production cost that huge power consumption produces has not only weakened the market competitiveness of China textile enterprise, more because the energy consumption accounting height of our textile enterprise, some place is in order to reach the requirement of energy-saving and emission-reduction, limited newly added equipment, simultaneously existing equipment is carried out limit production, some can only go into operation 9 months in local 1 year, had produced serious social concern, had influenced the construction of harmonious society.
At said structure, a kind of improved plan is to consider directly main motor to be replaced by well behaved permanent magnet AC synchronous servo motor.But still can there be two problems in this improvement, and the first is along with the increase of power, and the price of servomotor will be multiplied, thereby powerful servomotor and controller price are very expensive, very uneconomical; Next is the not variation of improvement, the particularly efficient of winding mechanism and transversing mechanism of power transmission loss of existing pattern.
