According to the rolling wheel friction tensioner, the pressing force, acting between the friction block and the tension rolling wheel, of the spring can be changed by rotating the adjusting wheel so that the purpose of adjusting warp tension can be achieved, and the adjusting mode is quite convenient to use. When the rolling wheel friction tensioner provides tension for warp, the warp does not move relative to the surface of the thread passing groove, and thus abrasion is greatly reduced.
Description
Technical field
The utility model relates to technical field of textile machine, is specifically related to a kind of roller friction tension device.
Background technology
Warping process is that the warp thread of certain radical is drawn from bobbin simultaneously, form even tension, arrangement parallel to each other warp thread piece, and length in accordance with regulations and width close wind are on warp beam or axle processed.The constant tension that must ensure warp thread in the process of reeling, so just needs special tensioner.Warping is completed by warping machines conventionally, and tensioner is assemblied on warping machines conventionally.On warping machines, conventional tensioner is that washer type tension force is put or twin columns pressure disc type tensioner now.These two kinds of tensioners are all to provide tension force by the sliding friction between warp thread and fixed static part, these two kinds of tensioners are at work because sliding friction all can cause certain wearing and tearing to warp thread, and adjusting is convenient not, the scope of warp thread control tension force is less.
Utility model content
For above problem, it is a kind of simple in structure that the utility model provides, and between yarn, adopt the roller friction tension device of static friction.
The utility model solves the technical scheme that its technical problem adopts: this roller friction tension device comprises tension force roller, fixed axis, friction block, regulating wheel; On described tension force roller, be processed with circumferential crossed beam trunking, described tension force roller is assemblied on fixed axis by coaxial bearing, the axial end portion of described tension force roller is equipped with the friction block being adjacent to, on the fixed axis in described friction block outside, be processed with external screw thread, described regulating wheel is assemblied in the external screw thread position of described fixed axis by helicitic texture; Spring compression is passed through in the outside of described friction block and the inner side of described regulating wheel.
As preferably, described fixed axis is circumferentially spacing by slide key to described friction block.
As preferably, the inner side of described regulating wheel is processed with columniform boss, and described spring housing is on boss; On described regulating wheel is axial, be processed with tapped through hole.
As preferably, the degree of depth of described crossed beam trunking is less than correspondence provides the radius of the warp thread of tension force, and this roller friction tension device uses in pairs, and the crossed beam trunking of two tension force rollers clamps warp thread.
As preferably, in the crossed beam trunking of described tension force roller, be coated with rubber layer.
The beneficial effects of the utility model are: this roller friction tension device can use in warping apparatus, is used for warp thread that tension force is provided.In use warp thread is wrapped in the crossed beam trunking of tension force roller, rotation regulating wheel, holds out against the end at tension force roller by spring by friction block; Warp thread, being torn while advancing, will be with the rotation of dynamic tension roller like this, and the frictional resistance that tension force roller is subject to will be transformed into the tension force of warp thread.Just can change the pressure of spring action between friction block and tension force roller by rotation regulating wheel like this, reach the object that regulates warp tension, this regulative mode is very convenient.When this device provides tension force for warp thread, warp thread and crossed beam trunking surface do not relatively move, and wearing and tearing greatly reduce.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in embodiment in Fig. 1 and Fig. 2, this roller friction tension device, it comprises tension force roller 1, fixed axis 2, friction block 3, regulating wheel 4; On described tension force roller 1, be processed with circumferential crossed beam trunking 11, described tension force roller 1 is assemblied on fixed axis 2 by coaxial bearing, the axial end portion of described tension force roller 1 is equipped with the friction block 3 being adjacent to, on the fixed axis 2 in described friction block 3 outsides, be processed with external screw thread, described regulating wheel 4 is assemblied in the external screw thread position of described fixed axis 2 by helicitic texture; The inner side of the outside of described friction block 3 and described regulating wheel 4 compresses by spring 5.
This roller friction tension device can use in warping apparatus, is used for warp thread that tension force is provided.In use warp thread 7 is wrapped in the crossed beam trunking 11 of tension force roller 1, rotation regulating wheel 4, holds out against the end at tension force roller 1 by spring 5 by friction block 3; Warp thread 7, being torn while advancing, will be with dynamic tension roller 1 to rotate like this, and the frictional resistance that tension force roller 1 is subject to will be transformed into the tension force of warp thread 7.Just can change spring 5 by rotation regulating wheel 4 like this and act on the pressure between friction block 3 and tension force roller 1, reach the object that regulates warp thread 7 tension force, this regulative mode is very convenient.When this device provides tension force for warp thread 7, warp thread and crossed beam trunking 11 surfaces do not relatively move, and wearing and tearing greatly reduce, and these warp thread are in when weaving, the better effects if of weaving cotton cloth.
As depicted in figs. 1 and 2, described fixed axis 2 is circumferentially spacing by slide key 6 to described friction block 3.Described like this friction block 3 is just only with along sliding shoe axially-movable, prevented the transfer of friction block 3 when tension force roller 1 rotates and spring 5, and device operation is more steady.
As depicted in figs. 1 and 2, the inner side of described regulating wheel 4 is processed with columniform boss 41, and described spring 5 is enclosed within on boss 41; On described regulating wheel 4 is axial, be processed with tapped through hole.Can prevent that like this spring 5 from rocking in the time of device assembling operation.
As shown in Figure 3, the degree of depth of described crossed beam trunking 11 is less than correspondence provides the radius of the warp thread 7 of tension force, and this roller friction tension device uses in pairs, and the crossed beam trunking 11 of two tension force rollers 1 clamps warp thread 7.The degree of depth of wire casing 11 is less than the radius of warp thread 7, can ensure that the crossed beam trunking 11 of two tension force rollers 1 clamps warp thread 7.Greatly improve near the maximum static friction force between yarn and two crossed beam trunkings 11 of position at two tension force rollers 1 like this, can prevent that like this warp thread 7 from crossed beam trunking 11, dynamic friction occurring.This device is increased greatly for the adjustable range of warp thread 7 tension force.
Specifically add man-hour, in the crossed beam trunking 11 of described tension force roller 1, be coated with rubber layer.The maximum static friction force of the crossed beam trunking 11 that can improve like this tension force roller 1 to warp thread.
