Description
Technical field
The utility model relates to a kind of chemical fibre process equipment, especially a kind of terylene multiple roll drafting system.
Background technique
It is raw material that polyester fiber, which is with natural polymer or artificial synthesized high-molecular compound, is spun by preparation
The processes such as silk stock solution, the spinning and post-processing fiber obtained with textile performance.The manufacture of polyester fiber is usually first nothing
Spinning melt or solution is made in machine object, then by filtering, metering, liquid thread is extruded as by spinning head, then solidify and
At fiber.Fiber at this time is known as as-spun fibre, its mechanical property is very poor, it is necessary to could accord with by a series of post-processing procedures
Close textile process and requirement.Post-processing includes carrying out drawing-off to fiber, makes macromolecular or structural unit edge in as-spun fibre
Fiber axis orientation, to improve the mechanical property and dimensional stability of fiber.Existing drafting machine is more to the extruding of fiber filament piece
Increase an extruding drum using in the side of drawing-off roller, passes through matching between the drawing-off roller of the extruding drum corresponding thereto
The extruding completed to fiber filament piece is closed, this squeezing effect is not ideal enough, and fiber filament piece still will appear on drawing-off roller to be beaten
Sliding phenomenon.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of terylene multiple roll drawing-off dresses
It sets.
To achieve the above object, the utility model uses following technical scheme:
A kind of terylene multiple roll drafting system comprising rack, multiple levels are rotatably provided in the upper draw roll in rack
With lower draw roll, upper draw roll and lower draw roll are staggered up and down, and the rack includes upper drawing-off roller frame, upper draw roll setting
In upper drawing-off roller frame, the upper drawing-off roller frame can be moved up and down with respect to rack, and the both ends of the upper drawing-off roller frame pass through spring
It is connect with rack, the middle part of upper drawing-off roller frame is equipped with slide-and-guide bar, and rack is equipped with sliding guide sleeve, the insertion of slide-and-guide bar
Upper moving up and down for drawing-off roller frame is oriented in sliding guide sleeve, multiple upper draw rolls connected by upper drawing-off roller frame and
Synchronization lifting.
The distance at the lower draw roll interval of two sides is less than the diameter of upper draw roll below the upper draw roll, so that on described
Its outer circumference surface and the two lower draw roll outer circumference surface are tangent when draw roll moves down in place.
The multiple upper draw roll includes at least a rubber rollers.
The axis of the upper draw roll is parallel with the axis of lower draw roll.
The utility model uses above technical scheme, and when drawing-off, dacron thread piece is alternately wrapped in draw roll and lower drawing-off
On roller, dacron thread piece to form tension due to pullling when advancing, and upper drawing-off roller frame moves down under tension, upper drawing-off
The distance at roller and lower draw roll interval reduces, and dacron thread piece is coated on the increase of the area in draw roll, and frictional force increases, dacron thread
The speed that piece advances is faster, and the pulling tension that dacron thread on piece is formed is bigger, and since the elasticity modulus of spring is constant, deformation is got over
Greatly, i.e., upper draw roll and the distance at lower draw roll interval are smaller, and it is bigger that dacron thread piece is coated on the area in draw roll, frictional force
Bigger, according to the forward speed automatic adjusument of dacron thread piece, avoid that fiber filament piece has skidded on drafting machine roller shows
As, simultaneously because under the action of silk piece tension, by silk piece oil and water squeeze out, improve drafting machine to the deoiling of silk piece,
Go water effect.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is a kind of structural schematic diagram of terylene multiple roll drafting system of the utility model；
Fig. 2 is the utility model side structure schematic diagram.
Specific embodiment
As shown in attached drawing 1 or 2, the utility model include rack 1, multiple levels be rotatably provided in rack 1 on lead
Roller 2 and lower draw roll 3 are stretched, upper draw roll 2 and about 3 lower draw roll are staggered, and the rack 1 includes upper drawing-off roller frame 11,
Upper draw roll 2 is arranged in upper drawing-off roller frame 11, and the upper drawing-off roller frame 11 can be moved up and down with respect to rack 1, the upper drawing-off
The both ends of roller frame 11 are connect by spring 4 with rack 1, and the middle part of upper drawing-off roller frame 11 is equipped with slide-and-guide bar 5, are set in rack 1
There is sliding guide sleeve 6, slide-and-guide bar 5 is inserted into sliding guide sleeve 6 and is oriented to upper moving up and down for drawing-off roller frame 11, more
A upper draw roll 2 is connected by upper drawing-off roller frame 11 and synchronization lifting.
Further, the distance that the lower draw roll 3 of the 2 lower section two sides of upper draw roll is spaced is less than the straight of upper draw roll 2
Diameter, so that its outer circumference surface and two lower 3 outer circumference surface of draw roll are tangent when the upper draw roll 2 moves down in place.
Further, the multiple upper draw roll 2 includes at least a rubber rollers.
Further, the axis of the upper draw roll 2 is parallel with the axis of lower draw roll 3.
When the utility model drawing-off, dacron thread piece is alternately wrapped in draw roll 2 and lower draw roll 3, and dacron thread piece exists
Tension is formed due to pullling when advance, upper drawing-off roller frame 11 moves down under tension, upper draw roll 2 and lower draw roll
The distance at 3 intervals reduces, and dacron thread piece is coated on the increase of the area in draw roll, and frictional force increases, the speed that dacron thread piece advances
Degree is faster, and the pulling tension that dacron thread on piece is formed is bigger, since the elasticity modulus of spring 4 is constant, deforms bigger, i.e., upper drawing-off
The distance at roller 2 and lower draw roll 3 interval is smaller, and dacron thread piece is coated on that the area in draw roll is bigger, and frictional force is bigger, according to
The forward speed automatic adjusument of dacron thread piece avoids fiber filament piece the phenomenon that having skidded on drafting machine roller, while by
In under the action of silk piece tension, by silk piece oil and water squeeze out, improve drafting machine to the deoiling of silk piece, go water effect.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention, within the spirit and principle of the utility model,
Any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.
