Description

Spandex silk winding head

Technical field

The utility model relates to the building mortion in a kind of spinning equipment, relates to a kind of spandex silk winding head specifically.

Background technology

At present, continuous polymerization, the full continuous production processes of high speed spinning are mainly adopted in spandex production, and the whole production flow process mainly is divided into four operations: A. polymerization process B. spinning process C. postprocessing working procedures D. refining step.Spinning technique is meant that mainly the stoste that transports from spinning tank flows to filament spinning component by gear wheel metering pump.After the extrusion nozzle ejection, enter spinning channel, stoste is frozen into tow.On winding head, be rolled into the bobbin of constant weight through false twisting, after oiling.Winding head is a most important equipment in the spinning technique, and the rotating speed height is made processed complex, accounts for about 60% of spinning process cost, belongs to most important production facilities in the spandex production.

In existing technology, the effect of spandex winding head is the bobbin (being commonly called as spinning cake) that spandex continuous yarn is wound into constant weight, mainly constituted, referring to accompanying drawing 8,9 by unit head 3, touch roll 10, the guide wire apparatus 9 that traverses, take up roll 1, rotating disk 2 and electrical control gear.Every winding head has two take up rolls up and down, reach constant weight when (expiring volume) when being wound on a spinning cake on the take up roll, then rotating disk (above take up roll is housed) begins to rotate, automatically switch to another root take up roll (empty roller to be rolled up) and go up the continuation spinning, this kind winding head is commonly referred to as full automaticity and switches winding head.Along with the continuous expansion that spandex accounts for chemical fibre market, spandex manufacturer is increasingly competitive, and in recent years, for increase productivity, winding head presents multifibres cake trend, this means the output growth of finished silk in the unit time, and productive costs changes seldom.Meet spandex manufacturer and pursued the target of production capacity substantially.But this trend has been subjected to certain limitation, mainly shows, take up roll lengthening itself, the seal wire roller supporting with winding head also extends, the difficulty of processing of take up roll significantly improves, and the vibration and the noise of winding head itself significantly increase, and the conformability that the spandex spinning cake is shaped is difficult to be guaranteed.

Summary of the invention

The purpose of this utility model provide at existing weak point in the above-mentioned prior art just a kind of can be bigger utilize machine space, make the novel spandex silk winding head that unit spandex silk output is obviously improved.

The purpose of this utility model can realize by following technique measures:

It comprises the unit head that is loaded on the frame spandex silk winding head of the present utility model, be provided with the rotating disk that can rotate around self central axis that horizontal direction is extended at the front end of unit head, rotating disk front end face upper edge center of turntable parallel axes be provided with two with cantilevered fashion extend forward can be around the take up roll of self rotational, above rotating disk, be provided with sliding case, the rear end of sliding case is by being arranged on the guidepost in the unit head casing and being used to drive sliding case is installed in unit head as the lift cylinder of upper and lower displacement campaign along guidepost front end, in the mode of cantilever design the touch roll bearing that extends forward and the guide wire apparatus that traverses are installed side by side at the front end of sliding case, touching on the roller bearing, touch roll is installed and is used to drive touch roll along its length direction around himself axis high speed revolution engine installation, wherein, front end at unit head is provided with a left side, right two rotating disks that can rotate around self central axis that horizontal direction is extended, and the gyratory directions of two rotating disks is opposite; Each rotating disk front end face upper edge center of turntable parallel axes be provided with two with cantilevered fashion extend forward can be around the take up roll of self rotational; Front end at sliding case is equipped with two touch roll bearings that extend forward side by side with cantilevered fashion, touching its length direction of roller bearing upper edge at each is equipped with a touch roll and is used to drive touch roll around himself axis high speed revolution engine installation, the described guide wire apparatus that traverses is arranged between left and right two touch rolls, and is provided with traverse motion threadguide in this guide wire apparatus and arranged on left and right sides of traversing.Because the guide wire apparatus that traverses described in the utility model has only a cover, left and right two touch rolls shared one overlap the guide wire apparatus that traverses, adopt such structure design, can reduce the width of unit head significantly, make its structure compact more, and the Silk Road can fully reduce the spacing of two rotating disks at the middle part of two rotating disks, fully improves the space efficiency of left and right directions.

The gyroscopic movement of left and right two rotating disks that are arranged side by side in the utility model is by being loaded on be meshing with each other a pair of gear and being realized by motor-driven transmission gear of being meshed with a gear in two gears on two rotary disk driving shafts respectively.

The principle of work of the utility model winding head is as follows: from the take up roll coiling, along with the increase gradually of spinning cake diameter, sliding case moves on beginning gradually, and the contact pressure between touch roll and the take up roll is controlled by an accurate voltage regulating valve.When the spinning cake on the take up roll that is wound on place rotating disk separately respectively reaches constant weight (full volume), move on sliding case is quick again, latter two rotating disk begin to rotate, make the another take up roll that is positioned on each autorotation disk forward normal spinning position to from position to be spooled, and the take up roll that makes full volume forwards debatching district, below to, finishes whole change action.Sliding case fast on to move be to realize by lift cylinder (the logical high pressure air of cylinder this moment), touch roll during normal spinning is drive roll (being dragged by synchronous dynamo), be pressed on the take up roll with certain contact pressure, driving take up roll constant linear velocity ground rotates, because two touch rolls equate with contact pressure maintenance between two take up rolls, silk distributes in the guide wire apparatus bilateral symmetry of traversing, so the quality of the spandex silk that spins can be guaranteed.The gyratory directions of two touch rolls is opposite, correspondingly the gyratory directions of two take up rolls is also opposite, when the spinning cake diameter reached the setting value of technological requirement, rotating disk will drive take up roll simultaneously and switch, for the spinning cake of avoiding two take up rolls to reel is interfered, during switching, spinning cake is the center with the axis of rotating disk all, rotates to two outsides of unit head respectively, so, the gyratory directions of two rotating disks also is opposite, and the revolution of two rotating disks is to drag by a cover actuating device.

The utility model compared with prior art, owing to adopted two rotating disks, four take up rolls, the cover guide wire apparatus that traverses, also just make structure seem compact, improved the space service efficiency to greatest extent, also guaranteed simultaneously the Silk Road equal in length of guide wire apparatus both sides, deflection angle equates, thereby the tension force that has guaranteed the spandex silk is identical, can draw better spinning cake profile.The output of winding head is doubled under equal technological condition, has reduced the equipment investment cost of spandex manufacturer.
