Abstract

To increase a performance for spreading a cloth by adding a specific function to a roll for spreading the cloth in order to spread the cloth without passing screw rolls many times in a processing process of the cloth in scouring and dyeing. In this roll for spreading a cloth, convex materials for spreading the cloth are arranged on the periphery surface of a roll with slanting in the direction of a rotation axis and the convex materials are constituted to have two or more of the periphery ends of the convex material and lengths of the rotation axes. Thus, a flapping action is added together with spreading action to the cloth and the spreading of the cloth is efficiently carried out with removing persistent wrinkles and foldings generated in the cloth.

Description

Opening roller

The present invention relates to used opening roller in the former cloth process engineering.

In former cloth process engineerings such as concise and dyeing, former cloth is not necessarily constantly to carry out under the state of width expansion.In general, adopt the result of former cloth extension width in working fluid of natural material and artificial silk to be, in the calendering engineering, former cloth has folding wrinkle easily, in the occasion with liquid-flow dyeing machine beam look, former cloth becomes the state that is screwed in together, therefore the wrinkle of twisting.Be used for the embossing roller of long former cloth in the width expansion, in order former cloth not to be applied the power of very large sweep, usually adopt on the circumferential surface of common cylindrical roller, from the mid portion of roller, the so-called embossing roller of the member of protrusion is set continuously by dextrorotation and left-handed helical form to the right left.Also have, if the friction between former cloth and the embossing roller not quite to a certain degree, then the open-width effect just can not be given full play to.So the air of on the surface of embossing roller, jetting, constitute the member that protrudes with brush, friction is strengthened.In general, when the peripheral speed of above-mentioned embossing roller was three times of left and right sides of pace of former cloth, effect was better, can set gyratory directions is the promptly suitable direction of direction of impelling former cloth to advance, but, according to the kind of former cloth with add condition, also can be set at contrary direction.But, when the former cloth of a part was in folded state, once by helical rotor, fully therefore open-width just had the problem of necessary several times by embossing roller.Also have,, the following describes with roller of the present invention as opening roller in order to distinguish embossing roller and roller of the present invention in the past.

The problem that the present invention will solve is, just can open-width in order to make former cloth several times by embossing roller, and additional special function on opening roller,

Fig. 1 is a perspective view, shows an embodiment of opening roller of the present invention;

The perspective view of Fig. 2 for amplifying shows enlargedly among Fig. 1 and lives part with the dot-dash coil.

Fig. 3 is a side view, shows the duty of opening roller.

Fig. 4 is a perspective view, shows the opening roller that another embodiment of configuration is cut apart in the arrangement that spirality is protruded member.

Fig. 5 is a side view, shows another embodiment that makes the opening roller of basic configuration with ellipse.

The present invention is because the structure from the axis of rotation of roller to the length of the excircle end that protrudes member 4 Become to have at least two or more, and on the outer surface of roller, will protrude member with respect to revolution Axis direction is pressed continuous and/or interrupted state setting for the direction that tilts, and becomes opening roller, Therefore when making this opening roller revolution, be attached with the function that former cloth is beated.

Also have, the protrusion member that is provided with on the roller outer surface preferably has a part at least by the plane excision along the axis of rotation that is parallel to roller, has polygon.

In addition, it is the ellipse at center that the protrusion member that is provided with on the outer surface of roller also can be arranged to the axis of rotation.

Embodiments of the present invention are described below with reference to the accompanying drawings.

Fig. 1 is a perspective view, shows the opening roller 1 that uses in the former cloth dyeing relevant with the present invention.In roller 2, the axle of its two supports can be run through roller 2 and is provided with, and turn round with motor (not shown) speed in accordance with regulations.On the outer surface of roller 2, reach left the fixing high 10mm of welding respectively to the right from the mid portion of roller, the band shape of wide 3mm is protruded member 4.This protrudes member 4 is the band steel bending machining of specified altitude and width to be arranged, be beforehand with curl, it is entrenched on the roller and in its contact portion welds then.In Fig. 2, amplify and to show part of living shown in Figure 1 with the dot-dash coil.In the present embodiment, protrude the part cut surface excision tangent of the outer surface of member 4, and, be provided with as face 5 along circumferential positions every 120 degree with the outer surface of roller 2.Fig. 3 shows the side view of this state of looking from a side of axle 3.Former other transportation means of cloth 6 usefulness is pressed the top of the direction of arrow B by expander, and is using guide roller 7, and 7-1 carries out when former cloth 6 is contacted with expander 1.Under this state, if direction in arrow A, about 3 times peripheral speed with the transporting velocity of former cloth 6 makes opening roller 1 revolution, then former cloth 6 returns again between with position shown in the chain-dotted line and former cloth position and moves up and down, and just former cloth is played the open-width effect by the protrusion member 4 of helical form setting.Therefore, become the part of rugosity, owing to vibrating and scraping the slurry effect, with regard to easy open-width.

In the present embodiment, tangent line with the excircle of roller 2 will protrude member 4 excisions, formation face 5, but, in the occasion that the length L 2 from the axis of roller to the length L 1 of face 5, from axis to the peripheral edge portion that protrudes member 4 is arranged, the discrepant part of the length of L1 and L2 have at least one just passable, not necessarily to constitute face 5 with the tangent line of roller excircle.But,,, preferably be provided with more than two in order to make weight not with respect to gyroaxis off-centre because opening roller is rotating.

In the above-described embodiments, protrude being arranged as of member 4 and dispose continuously, but also can will protrude member 4 incisions as shown in Figure 4, constitute and protrude member 4-1 and parallel moving, and protrusion member 4-2,4-3 are set equally, be used to carry out open-width by spirality.

Fig. 5 shows the side view of the different example of the length apart from the axis of rotation of roller of looking from a side of axle 3.Protruding member is that fundamental form constitutes opening roller 1-1 with the ellipse.On position, opposite with respect to the axis of roller 2, fixedly panel 8,8-1, and from the center of roller, will protrude in its outside member 9 respectively to the left and right direction by left-handed, be rolled into helical form by dextrorotation, on roller, fix.When making length L 3 from the axis of rotation of roller to the outer peripheral edges of protruding member 4, L4 in the case, produce 3 two of short length L, 4 two of long length L.Identical with previous embodiment, such opening roller 1-1 can simultaneously make former cloth vibration, one side open-width when revolution.

According to can be to the additional opening roller of the present invention of former cloth with the function of beating, the wrinkle that produces on former cloth in process engineerings such as concise and dyeing is as long as once pass through opening roller with former cloth, just can launch fully, carry out open-width, therefore can processing unit (plant) few place, leeway is set, also can carry out open-width effectively.Also have, at the folding state of some former cloth, former cloth is open-width fully also, particularly is used in the processing that thick craft weaves cotton cloth, and its interaction energy is given full play to.
