Description
Technical field
A kind of the present invention relates to textile technology field, more particularly to tensioner.
Background technology
In textile technology field, when cloth arranges rolling, cloth is transmitted typically on multipair spaced live-roller.
Specifically, cloth is clamped between a pair of live-rollers, so that certain frictional force between cloth and live-roller, is produced, so as to
Cloth is conveyed using live-roller.In order that cloth has some tension certain to make to have after cloth rolling in course of conveying
Consistency, generally, arranges a strainer between two pairs of live-rollers, and the strainer makes cloth produce some tension.
In prior art, for tensioning cloth strainer include one for be resisted against tensioning wheel on cloth and
For pushing against tensioning wheel so that tensioning wheel is resisted against the spring on cloth with certain pretightning force.This structure is actually spring and leads to
Crossing tensioning wheel and tension force being provided for cloth, the compression degree of spring is bigger, and the tension force of cloth is bigger, and the compression degree of spring is less,
The tension force of cloth is less.But as the coefficient of elasticity of spring is certain, the compression zone of spring is also certain, and therefore, spring is only
A range of tension force can be provided for cloth.One more prominent shortcoming of this structure is, due to the Reusability of spring, spring
Fatigue failure can occur, so that its coefficient of elasticity reduces, finally enough tension force can not be provided for cloth, affect cloth rolling
Consistency afterwards.

Description of the drawings
Fig. 1 is that the tensioner of the present invention is in the schematic diagram compared with small tension receiving coil state.
Fig. 2 is the schematic diagram of the tensioner in larger tension state of the present invention.
Specific embodiment
For making those skilled in the art be better understood from technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
Formula elaborates to the present invention.
As depicted in figs. 1 and 2, embodiment of the invention discloses that a kind of tensioner, the tensioner is for for two pairs
Cloth 15 between live-roller 14 provides tension force.The tensioner is specifically included：Mounting seat 1, fairlead 2, lead column 3, tensioning
Wheel 4, slide block 5 and spring 6.Mounting seat 1 is fixed on for transmitting the integral device of cloth 15, and is located at two pairs of live-rollers 14
Between cloth 15 lower section；What fairlead 2 was vertical is fixed in mounting seat 1, and opens up one on jacket wall along the axial direction of fairlead 2
Vertical slots；Lead column 3 is arranged in fairlead 2, and fairlead 2 and lead column 3 have and cooperate and vertical direction extends
Gathering sill and guide rail, so that lead column 3 can be vertically moved freely set 2 is oppositely oriented, occur to turn without being oppositely oriented set 2
Dynamic；Tensioning wheel 4 is fixed on the upper end of lead column 3, and which is connected to the lower surface of cloth 15 so that cloth 15 produces some tension；Sliding
Block 5 be capable of level slide closer or far from fairlead 2；Slide block 5 fixes a baffle plate 13 away from the side of fairlead 2, and spring 6 sets
Put between baffle plate 13 and slide block 5 to push against slide block 5 towards 2 direction of fairlead.The present invention it is critical only that：Arrange on slide block 5
One inclined-plane 8 that can adjust angle of inclination, arranges a guide part in lead column 3, and the guide part is stretched out by vertical slots
Outside fairlead 2, stretch to slide block 5 and contact with the inclined-plane 8 of slide block 5 so that inclined-plane 8 by guide part push against lead column 3 so that
Tensioning wheel 4 is moved to 15 direction of cloth, or tensioning wheel 4 drives guide part by lead column 3, by inclined-plane 8 to away from guiding
The direction pushing and pressing slide block 5 of set 2 is so that spring 6 is compressed.
Said structure can expand range of accommodation of the tensioning wheel 4 to the tension force of cloth 15, and its reason is：Cloth 15 is produced
Raw tension force is mainly provided to the pretightning force of cloth 15 by tensioning wheel 4, and the pretightning force is provided indirectly by the elastic force of spring 6, not
In the case of the frictional force of consideration 3 gravity of lead column and other moving parts（Even if actually considering gravity and frictional force, effect
Fruit is also identical）, pretightning force F1 with the elastic force F2 relations of spring 6 is：F1=F2/tga, wherein：A be inclined-plane 8 relative to level
The angle of inclination in face, due to the coefficient of elasticity of spring 6 constant, when spring 6 produces the pushing force of a certain numerical value, its compression degree
（Here can be scaled horizontal displacement）Be certain, and pretightning force can by change inclined-plane 8 angle of inclination can have multiple numbers
Value.That is, under different angles of inclination, in the case where 6 compression degree of spring is constant, tensioning wheel 4 can provide difference
Pretightning force, if assume spring 6 be set directly in the way of vertical below lead column 3, by adjust angle of inclination, a certain
Under pretightning force, tensioning wheel 4 can have different vertical positions, spring 6 to there is different compression degrees, that is, form different equivalents
Coefficient of elasticity.
In sum, by the angle of inclination on change inclined-plane 8 so that spring 6 has different equivalent coefficients, when cloth 15
When needing with larger tension range, as shown in Fig. 2 reducing the angle of inclination on inclined-plane 8, i.e. the numerical value of a reduces, then equivalent system
Number increase, so that the pretightning force increase of tensioning wheel 4, finally increases the tension adjustment range of cloth 15.In the same manner, work as cloth
15 need with during compared with small tension receiving coil scope, as shown in figure 1, increasing the angle of inclination on inclined-plane 8, i.e. the numerical value of a increases, then equivalent
Coefficient is less, so that the pretightning force of tensioning wheel 4 reduces, finally reduces the tension adjustment range of cloth 15.
The present invention changes the equivalent coefficient of elasticity of spring 6 by the angle of inclination on change inclined-plane 8, and then provides different
Power scope, i.e. higher range or relatively low scope, and by adjust angle of inclination, can make up spring 6 occur failure and to elasticity
The impact of coefficient.
In a preferred embodiment of the invention, guide part includes the installation for being fixed on lead column 3 and extending towards inclined-plane 8
Arm 9 and the guide pad 10 for being articulated in 9 free end of installing arm and abutting with inclined-plane 8.Guide pad 10 slides on inclined-plane 8.
As a kind of selection, on slide block 5, be provided with rotor 7, rotor 7 can opposing slider 5 rotate and fix, inclined-plane
8 are formed on rotor 7.
Used as a kind of selection, rotor 7 is segmental rotor, and inclined-plane 8 is the planar section of segmental rotor outer peripheral face.
For inclined-plane 8 can be made fixed after the regulation of angle of inclination, bearing pin 12, slide block 5 is fixed with one end of segmental rotor
On offer long arc-shaped holes 11, bearing pin 12 is locked by nut after wearing long arc-shaped holes 11.When needing to adjust angle, nut is sent in rotation,
Tightening nut is again adjusted after angle.
For preventing guide pad 10 from departing from inclined-plane 8, the first dovetail slideway on wire block, is formed with, on inclined-plane 8, offers the
One dovetail groove, the first dovetail slideway are arranged in the first dovetail groove, and guide pad 10 slides along the first dovetail groove.
For making slide block 5 slide towards fairlead 2, the second dovetail slideway, the upper installation of mounting seat 1 on slide block 5, is formed with
The second dovetail groove extended towards fairlead 2 is offered on face, and the second dovetail slideway is arranged in the second dovetail groove, slide block 5
Slide along the second dovetail groove.
Above example is only the exemplary embodiment of the present invention, is not used in the restriction present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can be made respectively to the present invention in the essence and protection domain of the present invention
Modification or equivalent is planted, this modification or equivalent also should be regarded as being within the scope of the present invention.
