Description
Technical field
The present invention a kind of for solve Loose tube after-contraction what press that formula draw-gear relates to is a kind of special equipment for solving Loose tube after-contraction phenomenon for Loose tube production field.
background technology:
In conventional loose tube production technology, extruder draws synchronous, to control the parameter such as diameter, wall thickness of sleeve pipe with remaining length.In process of production, the friction of water and shell material and remaining long traction all can make shell material produce internal stress to the traction of sleeve pipe, and along with the change of time and temperature, sleeve pipe molecular structure changes, formation after-contraction phenomenon.
The after-contraction phenomenon of shell material and speed of production have certain relation, facts have proved, speed of production is faster, and the after-contraction phenomenon of sleeve pipe will be more obvious.Like this, the raising of the speed of production of Loose tube is just limited.Due to the existence of sleeve pipe internal stress, the after-contraction of Loose tube also can accompany time to time change more and more obvious.Meanwhile, the after-contraction phenomenon of Loose tube also can produce obvious change along with the temperature in production process.
The existence of Loose tube after-contraction phenomenon brings suitable trouble to the lifting of speed of production and construction.In actual production process, control excess fiber length by methods such as remaining long traction, tension force controls, counteract the sleeve pipe after-contraction of a part.But these methods all fundamentally cannot solve the after-contraction phenomenon of Loose tube.
Summary of the invention
The present invention seeks to provide a kind of for above-mentioned weak point and press formula draw-gear for what solve Loose tube after-contraction, in order to improve the after-contraction phenomenon of Loose tube, control excess fiber length, reduce production cost, develop and press formula draw-gear for what solve Loose tube after-contraction.This device is placed in the middle of cross-head and remaining long hauling machine, and its speed is higher than remaining long hauling speed.Like this, Loose tube plays the effect of pressing while cooling, and after sleeve pipe leaves remaining long traction, " after-contraction " phenomenon is reduced greatly.
A kind of formula draw-gear that presses for solving Loose tube after-contraction takes following technical scheme to realize:
A kind of formula draw-gear that presses for solving Loose tube after-contraction comprises swing arm, rotating shaft, tension pick-up, bearing block, cylinder, servomotor, initiatively train and driven train.
Tension pick-up, servomotor, initiatively train swing arm be equipped with; Swing arm, under the drive of rotating shaft, is that fulcrum produces rotation with bearing block.The rotational angle of swing arm is reflected by tension pick-up, and by signal transmission to servomotor, for the rotating speed of on-line tuning servomotor, thus changes the hauling speed of initiatively train.Initiatively train is installed on the piston rod of cylinder head, along with the flexible relative distance that can regulate between driven train of cylinder, forms the clamping to Loose tube, thus realizes pressing Loose tube.Driven train is fixed in frame together with bearing block.
Described active train and driven pulley are fastened and leash, pinch roller are all housed.
advantage of the present invention:
1, pressing formula draw-gear is placed between head and remaining long hauling machine, can on-line control compaction forces and hauling speed as required;
The use of 2, pressing formula draw-gear can improve Loose tube speed of production greatly, enhances productivity;
3, the after-contraction phenomenon of sleeve pipe can be eliminated owing to pressing formula traction, price therefore can be used aborning relatively cheap but the slow PP material of post crystallization, significantly can reduce the cost of raw material like this;
The successful removal of 4, after-contraction phenomenon can also make the production of less internal diameter sleeve pipe become possibility.
5, be conducive to the successful transition of ointment formula sleeve pipe to dry sleeve, greatly improving execution conditions, improving the quality of products.
6, be conducive to improving product quality, improve production qualification rate;
Accompanying drawing explanation
below with reference to accompanying drawing, the present invention is further described:
Fig. 1 is the structural front view that formula draw-gear is pressed in the present invention.
Fig. 2 is the structure left view that formula draw-gear is pressed in the present invention.
In figure: 1, swing arm, 2, rotating shaft, 3, tension pick-up, 4, bearing block, 5, cylinder, 6, servomotor, 7, initiatively train, 8, driven train, 9, leash, 10, pinch roller.
Detailed description of the invention
With reference to accompanying drawing 1,2, press formula draw-gear and comprise swing arm 1, rotating shaft 2, tension pick-up 3, bearing block 4, cylinder 5, servomotor 6, initiatively train 7 and driven train 8.
Tension pick-up 3, servomotor 6, initiatively train 7 swing arm 1 be equipped with; Swing arm 1, under the drive of rotating shaft 2, is rotated for fulcrum produces with bearing block 4.The rotational angle of swing arm 1 is reflected by tension pick-up 3, and by signal transmission to servomotor 6, for the rotating speed of on-line tuning servomotor 6, thus changes the hauling speed of initiatively train 7.Driving wheel 7 is be installed on the piston rod of cylinder 5 head, along with the flexible relative distance that can regulate between driven train 8 of cylinder 5, forms the clamping to Loose tube, thus realizes pressing Loose tube.Driven train 8 is fixed in frame together with bearing block 4.Leash 9, pinch roller 10 be all equipped with initiatively train 7 and driven train 8.
In tank, in the middle of cross-head and remaining long hauling machine, increase by one press formula hauling machine.Like this, produce mobile under Loose tube is applicable to the clamping of the leash worked in the hot water at upper and lower two along production mode reform, and the speed of movement is higher than remaining long hauling speed.Like this, Loose tube enter press formula traction before be stretched, enter press formula traction after, due to press formula traction speed higher than remaining long hauling speed, Loose tube plays the effect of pressing while cooling, is formed " oversupply " of sleeve pipe opposed optical fibers.After sleeve pipe leaves remaining long traction, " after-contraction " phenomenon is reduced greatly, and excess fiber length obtains effective control.
Pressing in formula draw-gear, can also by selecting suitable to press rate (namely pressing the ratio of formula hauling speed higher than the speed of remaining long traction), can reach excess fiber length very steadily and casing shrink rate be almost the effect of " zero ".Thus improve " after-contraction " phenomenon even thoroughly solving sleeve pipe.
