The device comprises two support arms arranged on the frame arm in parallel, wherein the two support arms are connected through a cross rod, and the cross rod is arranged perpendicular to the movement direction of the curtain cloth; the cross rod is sleeved with a plurality of spanning support arms which rotate around the cross rod; a gravity roller which can rotate freely is arranged at the free end of the spanning support arm, and the gravity roller is contacted with the upper surface of the curtain cloth. The utility model discloses technical scheme assists the curtain cloth to lead out, effectively makes full width curtain cloth tension even, and the uniformity of layer width and angle is restrainted to the area when guaranteeing follow-up curtain cloth and decide to reduce the influence that layer width and angle are bad to tire performance is restrainted to the area.

Description

Device for assisting curtain fabric in opening

Technical Field

The utility model belongs to the technical field of tire preparation, a device that supplementary curtain cloth was led out is related to.

Background

The belted layer is a framework material of the tire, plays a role in protecting a tire body cord fabric, preventing the tire tread from deforming and improving the wear resistance and the driving stability of the tire, and the cutting angle and the width consistency of the belted layer directly influence the quality and the performance of the tire. The flatness of the curtain cloth after unwinding influences the uniformity of the tension of the whole curtain cloth, and further influences the cutting width and angle of the belt ply. Belt material with unqualified cutting width and angle needs to be manually removed and discarded, which wastes time and energy of staff and causes resource waste.

Therefore, the device for assisting the curtain cloth to be guided open is manufactured, so that the tension force is uniformly applied to the eyebrow when the curtain cloth is guided open.

SUMMERY OF THE UTILITY MODEL

The utility model discloses technical scheme provides supplementary curtain cloth and led device of opening, and aim at guarantees the curtain cloth at the tension homogeneity and the roughness of pulling the in-process, promotes the curtain cloth and cuts the uniformity of width to it is bad to reduce the tire that is brought by curtain cloth tension inequality.

In order to achieve the purpose, the utility model is realized by adopting the following technical scheme:

the utility model provides a device for assisting in guiding open cord fabric, which comprises two support arms arranged on the frame arm in parallel, wherein the two support arms are connected through a cross rod, and the cross rod is arranged perpendicular to the movement direction of the cord fabric; the cross rod is sleeved with a plurality of spanning support arms which rotate around the cross rod; a gravity roller which can rotate freely is arranged at the free end of the spanning support arm, and the gravity roller is contacted with the upper surface of the curtain cloth.

Furthermore, the two ends of the cross rod are detachably connected to the tail ends of the support arms through connecting ends respectively.

Further, the other end of the support arm is fixed on the frame arm through a fixed end.

Further, the surface of the gravity roller is provided with friction protrusions.

Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses technical scheme assists the curtain cloth to lead out, effectively makes full width curtain cloth tension even, and the uniformity of layer width and angle is restrainted to the area when guaranteeing follow-up curtain cloth and decide to reduce the influence that layer width and angle are bad to tire performance is restrainted to the area.

2. The utility model discloses technical scheme makes and simple installation, and the cost is cheap, is the device that the supplementary curtain cloth of a cost performance ratio is superior led out.

3. The utility model discloses the intervention of the reducible follow-up workman of technical scheme reduces workman intensity of labour.

Therefore, the utility model discloses technical scheme has higher practical value and economic value.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.

In the drawings:

FIG. 1 is a schematic structural view of the device for assisting the opening of the curtain cloth of the present invention;

FIG. 2 is a view showing the state of the device for opening the curtain cloth according to the present invention;

the respective symbols in the figure are as follows: the device comprises a support arm 1, a connecting end 2, a cross rod 3, a cross arm 4, a gravity roller 5, a fixed end 6, a frame arm 7 and curtain cloth 8.

Detailed Description

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The present invention will be further explained with reference to fig. 1 and 2.

The utility model discloses a supplementary curtain cloth is led device of opening, a serial communication port, including parallel arrangement in two support arms 1 on curtain cloth is led the frame arm 7 of opening and storing up the cloth device, the support arm other end passes through stiff end 6 to be fixed on the frame arm.

The two support arms are connected through a cross rod 3, and the cross rod is arranged perpendicular to the movement direction of the curtain cloth 8; the both ends of horizontal pole are connected at the support arm end through link 2 can be dismantled respectively.

The cross rod is sleeved with a plurality of spanning support arms 4 which rotate around the cross rod. A gravity roller 5 which can rotate freely is arranged at the free end of the spanning support arm and is contacted with the upper surface of the curtain cloth. The number of the spanning support arms and the gravity rollers can be properly increased or decreased according to the full width of the curtain cloth.

The friction bulge is arranged on the surface of the gravity roller, so that the friction force between the gravity roller and the curtain cloth is increased, and further the tension is provided for the curtain cloth.

In the course of the work, behind the curtain cloth unwinding equipment, through the horizontal pole below, when curtain cloth unwinding tension is inconsistent, every strides across support arm and gravity roller and all can rotate from top to bottom alone, relies on self weight to give curtain cloth with tension: when the tension of part of the curtain cloth is smaller, the gravity roller corresponding to the curtain cloth falls by the gravity of the gravity roller in a larger range, so that the corresponding curtain cloth part is stretched to provide tension for the curtain cloth, the uniformity of the tension of the curtain cloth is ensured, and the problem of inconsistent unwinding tension of the curtain cloth can be solved.

It is to be understood that the present invention has been described in detail with reference to the foregoing embodiments, and that modifications and equivalents of the various embodiments described above may be made by those skilled in the art, or some of the technical features may be substituted. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
