The invention relates to special equipment for avoiding post-contraction of a loose tube in the production field of loose tubes. The special equipment comprises a swing arm, a rotary shaft, a tension sensor, a bearing seat, an air cylinder, a servo motor, a driving wheel system and a driven wheel system, wherein the swing arm is provided with the tension sensor, the servo motor and the driving wheel system, and is driven by the rotary shaft to rotate by taking the bearing seat as a supporting point; a rotary angle of the swing arm is reflected through the tension sensor, and a signal is transmitted to the servo motor and used for adjusting the rotary speed of the servo motor in an online manner, so that the traction speed of the driving wheel system is changed; the driving wheel system is mounted on a piston rod at the head of the air cylinder, and a relative distance between the driving wheel system and the driven wheel system is adjusted along with the retraction of the air cylinder so as to clamp the loose tube, so that the loose tube is compressed; the driven wheel system and the bearing seat are fixed on a rack; and the driving wheel system and the driven wheel system are provided with traction belts and pressing wheels.
Description
Technical field
The present invention a kind of be used to solve loose sleeve pipe after-contraction what press that the formula draw-gear relates to is a kind of special equipment that is used for solving loose sleeve pipe after-contraction phenomenon for loose sleeve pipe production field.
Background technology:
In the loose process for producing casing of tradition, extruder and remaining long traction synchronously, with parameters such as the diameter of controlling sleeve pipe, wall thickness.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 variation of time and temperature, the sleeve pipe molecular structure changes, and forms the after-contraction phenomenon.
After-contraction phenomenon and the speed of production of shell material 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, just limited the raising of the speed of production of loose sleeve pipe.Because the existence of sleeve pipe internal stress, the after-contraction of loose sleeve pipe also can accompany time to time change more and more obvious.Simultaneously, the after-contraction phenomenon of loose sleeve pipe also can produce obvious variation along with the temperature in the production process.
The existence of pine sleeve pipe after-contraction phenomenon has brought suitable trouble to the lifting of speed of production with construction.In actual production process, by method control excess fiber lengths such as remaining long traction, tension force controls, offset a part of sleeve pipe after-contraction.But these methods all can't fundamentally solve the after-contraction phenomenon of loose sleeve pipe.
Summary of the invention
The present invention seeks to provide a kind of for above-mentioned weak point and press the formula draw-gear be used to what solve loose sleeve pipe after-contraction, in order to improve the after-contraction phenomenon of loose sleeve pipe, the control excess fiber length, Decrease production cost, developed be used for solving loose sleeve pipe after-contraction press the formula draw-gear.This device is placed in the middle of cross-head and the remaining long hauling machine, and its speed is higher than remaining long hauling speed.Like this, loose sleeve pipe plays the effect of pressing in cooling, and after sleeve pipe left remaining long traction, " after-contraction " phenomenon was dwindled greatly.
A kind ofly take following technical scheme to realize be used to the formula draw-gear that presses that solves loose sleeve pipe after-contraction:
A kind of formula draw-gear that presses be used to solving loose sleeve pipe after-contraction comprises swing arm, rotating shaft, tension pick-up, bearing block, cylinder, servomotor, active train and driven train.
Tension pick-up, servomotor, active train are housed in the swing arm; Swing arm rotates take bearing block as fulcrum under the drive of rotating shaft.The rotational angle of swing arm reflected by tension pick-up, and signal is passed to servomotor, is used for the online rotating speed of adjusting servomotor, thereby changes the initiatively hauling speed of train.Initiatively train is installed on the piston rod of cylinder head, along with cylinder flexible can regulate and driven train between relative distance, form the clamping to loose sleeve pipe, thereby realize pressing loose sleeve pipe.Driven train is fixed on the frame with bearing block.
Described active train and driven pulley are fastened leash, pinch roller all are housed.
Advantage of the present invention:
1, presses the formula draw-gear and be placed between head and the remaining long hauling machine, as required on-line control compaction forces and hauling speed;
The use of 2, pressing the formula draw-gear can improve loose sleeve pipe speed of production greatly, enhances productivity;
3, owing to pressing the after-contraction phenomenon that formula traction can be eliminated sleeve pipe, therefore can use aborning the relatively cheap but slow PP material of post crystallization of price, like this can the decrease cost of raw material;
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 finish ointment formula sleeve pipe to the successful transition of dry sleeve, greatly improve execution conditions, improve the quality of products.
6, be conducive to improve product quality, improve the production qualification rate;
Description of drawings
The present invention is further described below with reference to accompanying drawing:
Fig. 1 is the structural front view that the formula draw-gear is pressed in the present invention.
Fig. 2 is the structure left view that the formula draw-gear is pressed in the present invention.
Among the figure: 1, swing arm, 2, rotating shaft, 3, tension pick-up, 4, bearing block, 5, cylinder, 6, servomotor, 7, train initiatively, 8, driven train, 9, leash, 10, pinch roller.
The specific embodiment
With reference to accompanying drawing 1,2, press the formula draw-gear and comprise swing arm 1, rotating shaft 2, tension pick-up 3, bearing block 4, cylinder 5, servomotor 6, active train 7 and driven train 8.
Tension pick-up 3, servomotor 6, active train 7 are housed in the swing arm 1; Swing arm 1 rotates take bearing block 4 as fulcrum under the drive of rotating shaft 2.The rotational angle of swing arm 1 reflected by tension pick-up 3, and signal is passed to servomotor 6, is used for the online rotating speed of adjusting servomotor 6, thereby changes the initiatively hauling speed of train 7.Driving wheel 7 is to be installed on the piston rod of cylinder 5 heads, along with cylinder 5 flexible can regulate and driven train 8 between relative distance, form the clamping to loose sleeve pipe, thereby realize pressing loose sleeve pipe.Driven train 8 is fixed on the frame with bearing block 4.Initiatively on train 7 and the driven train 8 leash 9, pinch roller 10 are housed all.
In tank, in the middle of cross-head and remaining long hauling machine, increase by one and press the formula hauling machine.Like this, loose sleeve pipe upper and lower two mobile to producing along producer under applicable to the clamping of the leash of in hot water, working, and mobile speed is higher than remaining long hauling speed.Like this, the pine sleeve pipe is stretched before pressing formula traction entering, enter press the formula traction after be higher than remaining long hauling speed owing to pressing the speed of formula traction, the pine sleeve pipe plays the effect of pressing in cooling, form " oversupply " of the relative optical fiber of sleeve pipe.After sleeve pipe left remaining long traction, " after-contraction " phenomenon was dwindled greatly, and excess fiber length has obtained effective control.
In pressing the formula draw-gear, can also be by selecting the suitable rate (namely pressing the ratio that the formula hauling speed is higher than the speed of remaining long traction) of pressing, can reach excess fiber length very steadily and the sleeve pipe shrinkage factor is almost the effect of " zero ".Thereby improve even thoroughly solve " after-contraction " phenomenon of sleeve pipe.
