Abstract

The utility model relates to a high-speed spinning device for shaping on rayon silk tube, which belongs to the high-speed spinning device with viscose. The high-speed spinning device for shaping on rayon silk tube mainly comprises conveying pipes, spinnerets, a-shaped tube and a bathing groove. A coagulation groove is communicated with a reflux groove by a-shaped tube with small diameter, a conic shower nozzle matched with the shaped tube is arranged in the front relevant position of the shaped tube, a spinning guider is arranged near the outlet of the shaped tube, only a spinning disc is arranged between the spinning guider and the spinning hopper. If the utility model is transplanted and applied to the existing spinning device with viscose rayon, the spinning speed can reach to 120-140 meters per minute, the production can be increased by more than 30%, the investment is only the 1/3 of the investment of building a new factory, the labor condition can also be improved, and the high-speed spinning device for shaping on rayon silk tube is favorable to recycle carbon disulfide.

Description

High-speed spinning device for shaping on rayon silk tube

The utility model belongs to the viscose device for spinning, is specially adapted to acid centrifugal pot spinning machine and semi-continuous centrifugal formula spinning machine.

Existing acid centrifugal pot spinning machine and semi-continuous centrifugal formula spinning machine, the shaping of strand is to move in static solidification liquid, it is low to spin speed, approximately per minute is about 90 meters, if improve spinning speed then the quality of strand will seriously descend." the wet type device for spinning of artificial fibre " that Japan Patent proposes for 1963 38～No. 3956, be intended to solve monofilament fracture of wire in the pipeline building mortion and commercial scale implement in the problem of the degassing, its invention main points are that the control coagulating tank degree of depth makes it the monofilament surface degassing fully.The liquid level difference of using coagulating tank and drain tank realizes industrial production requirement.Select stream pipe general layout vertical or that the wide-angle more than 45 ° is installed on the structure for use, other aspects almost do not change.Its shortcoming is that this structure can't directly realize high speed spinning on the centrifugal and semi-continuous centrifugal formula spinning machine of existing acidity.

The purpose of this utility model is spinning head, spin duct, thread guide mechanism, spinning disc are rationally improved, improve spinning speed in the commercial process and guarantee the strand quality thereby be implemented in, and can be directly used in acid centrifugal and semi-continuous centrifugal formula spinning machine.

Shaped device in the viscose glue fiber tube described in the utility model, mainly form by carrier pipe, spinning head, forming tube and bath, between coagulating basin and liquid return trough, be communicated with a forming tube, be installed in the relevant position ， And of forming tube import front with the supporting taper spinning head of forming tube and dwindle the distribution area of spinneret orifice on the spinning head.Near the forming tube outlet is a thread guide mechanism, and thread guide mechanism can be single godet roller or two godet roller or traveller.A spinning disc is set between thread guide mechanism and spinning funnel.By strengthening the diameter of spinning disc, make it to match with thread guide mechanism, satisfy the requirement of spinning speed and strand drawing tension.When this device is used for acid centrifugal pot spinning machine, its existing two spinning discs can be kept to one.When it and existing semi-continuous centrifugal formula spinning machine adapted,, an original spinning disc can be saved by strengthening the diameter of roll dies.

Technical solution adopted in the utility model for the improvement of existing equipment, spin speed and improve, has found an effective approach, under the prerequisite of ensuring the quality of products, can bring up to 120 meters of per minutes with spinning speed, and maximum speed can reach more than 140 meters.If the speed of spinning by 120 meters of per minutes is calculated, can improve output 25～40%, and simplified equipment, investment only for newly found the factory 1/3.

Present technique portable and using on the existing viscose spinning machine, particularly suitable for existing R531 and R535 series spinning machine, and need not increase power.Because coagulating basin and liquid return trough are communicated with by forming tube, bathe the stream directed flow, thereby new, old body lotion is entirely different, can reduce the loss of pernicious gas, has improved working condition, helps the recovery of carbon disulfide.

Below with reference to the accompanying drawings embodiment of the present utility model is described further:

Fig. 1 is the utility model structural representation.

Carrier pipe 1 is flexible gooseneck, in its end taper spinning head 2 is installed, and the wire vent face is concentrated and is distributed in the face diameter of 3～8mm.Conic nozzle 2 is aimed at the import of forming tube 3, and forming tube 3 is preferably selected the glass tube or the plastic tube of corrosion-resistant and inner wall smooth for use.Forming tube 3 imports are arranged in coagulating basin 4, the other end stretches in the liquid return trough 5, pipe range is 550～800mm, bore is 4～10mm, body lotion is new liquid in the coagulating basin 4, and the body lotion in the liquid return trough 5 is old liquid, is keeping pressure differential between two grooves, bath is made the shared unit of many ingots, and every unit is provided with acid solution import and overfall separately.Godet roller 6 places the liquid return trough of the forming tube port of export, at godet roller 6 and 8 of spinning funnels a spinning disc 7 is set, and its diameter is 155～200mm, and is drop-down to guarantee stablizing strand.

When viscose enters the solidification liquid of coagulating tank 4 after spinning head 2 ejections from carrier pipe 1, under the convergence of the liquid of certain speed stream and guiding, flow through forming tube 3, solidify, form strand gradually while advancing, guide spinning disc 7 at the liquid return trough strand into through godet roller 6, enter spinning funnel 8 then.
