Description
Affiliated technical field
The present invention relates to the wind2 of chemical-fibres filaments, relate in particular to a kind of chemical-fibres filaments winding head pressure roller of minor diameter.
Background technology
Chemical-fibres filaments is wound into cylindrical package on winding head.In winding process, contact with spinning cake on the collet axis of bobbin all the time with the contact pressure set by pressure roller, pressure roller is by the bobbin chuck friction-driven, the genus passive type.Generally pressure roller is made as large-diameter hollow roller now, its reason is that the advantage of hollow roll is that rotor inertia is little, is applicable to passive type.But its advantage is also achieved its shortcoming simultaneously, says on the slave machining angle that being processed into hollow roll then must add the large pressuring roller diameter, so that the processing endoporus.Must will guarantee endoporus and outer circles man-hour adding, if can not guarantee its right alignment, need to remove too much amount of unbalance in doing dynamically balanced process, be to carry out in the endoporus of roll body and remove amount of unbalance, and operation easier is big, and reject rate is than higher.Because of being hollow roll body, rigidity is poor again, causes flexural deformation easily in the process of processing and use.From winding process, because of the roll body diameter bigger, tow is distance big (seeing the A size that Fig. 1 marks) from the profiled sheeting to the collet axis of bobbin, with the cornerite of pressure roller little (seeing the cornerite B that Fig. 1 marks), increase along with winding diameter, this just the tow overlapping phenomenon occurs inevitably, causes the vibration of winding head, the shaping of damage package, makes to be difficult to obtain the high capacity package that is shaped good when high-speed winding.Because of increasing gradually, spinning cake promotes the pressure roller rising again, so the collet axis of bobbin rotating speed is a continually varying.Winding speed is got by the pressure roller revolution speed calculating, but pressure roller is passive contacting with collet axis, has a slippage, and its linear velocity is not real winding speed.And pressure roller separates with collet axis of bobbin when switching repiece, and barrel velocity will descend naturally, and this coiling to the bottom silk of new spinning cake produces bad influence, and when the unwinding of road, back broken end and knocking over takes place easily.
Summary of the invention
The objective of the invention is in order to solve deficiency and the defective that present employed large-diameter hollow pressure roller exists, and the chemical-fibres filaments winding head pressure roller of a kind of novel minor diameter that proposes.Adopt by the solid roll body of the minor diameter of bearings at its two ends, and an end of pressure roller shaft is connected with motor by plunging joint.Since adopted the press-roller device of the chemical-fibres filaments winding head of said structure, at the spinning speed that improves the chemical-fibres filaments winding head simultaneously, the shaping and the unwinding that have also improved spinning cake.The prior art above shortcomings have been overcome.
The technical solution adopted for the present invention to solve the technical problems is: the roll body of described pressure roller is solid roll body, the spindle nose at pressure roller two ends is by bearings, one end of pressure roller shaft is connected with motor by coupler, be provided with fifth wheel between described bearing and the coupler, wherein the roll body diameter of pressure roller is less than the diameter of collet axis.
The roll body of described pressure roller is provided with balance hole.
The distance C of described tow between from the profiled sheeting to the collet axis of bobbin is less than A, and the cornerite D of tow on pressure roller is greater than cornerite B.
Described bearing is the biserial high-speed bearing.
Described motor is an asynchronous high-speed motor.
Described coupler is electrically connected with control setup.
The present invention is from material, and solid roll body adopts the raw MAT'L of special processing, can not cause flexural deformation because of the release of internal stress in the follow-up course of processing.Because do not need to process endoporus, so diameter can diminish under the condition that can reach requirement for dynamic balance as much as possible, and its processing technology is also adjusted, reduced manufacturing procedure, reduced difficulty of processing, improved yield rate.Again because of being solid roll body, when doing multistage kinetic balance, amount of unbalance can have the pressure roller outside face punching of quickening circle to remove in many places, be convenient to very much operation, this just not only can obtain the vibration velocity of high request easily, and reduced the vibration of winding head complete machine, improve the winding speed of chemical-fibres filaments winding head.
The invention has the beneficial effects as follows, for winding process, the solid roll body of minor diameter, shortened the distance (see C size that Fig. 2 mark) of tow between from the profiled sheeting to the collet axis of bobbin, increased the cornerite (see cornerite D that Fig. 2 mark) of fork type chemical-fibres filaments coiling tow on pressure roller simultaneously, make silk interlayer wire ring lay the position firm stable, can the anterior layer wire ring be walked about because of laying back layer wire ring.Coiling is the big and inside and outside unanimity of wire ring density between the cycle.When high-speed winding, the vibration velocity of complete machine also obviously reduces.Pressure roller is existing to be dragged by asynchronous high-speed motor, becomes initiatively from passive, can not be subjected to being affected and reducing because of having broken away from collet axis in the automatically switch speed of back pressure roller of winding head.
The press-roller device of chemical-fibres filaments winding head provided by the invention comprises the solid roll body of minor diameter, support roll body bearing and with pressure roller shaft one end bonded assembly motor.Since adopted the press-roller device of the chemical-fibres filaments winding head of said structure, at the winding speed that improves the chemical-fibres filaments winding head simultaneously, the shaping and the unwinding that have also improved spinning cake.
