Through adopting above-mentioned technical scheme, after the cloth comes out from the unwinding roller, on the carry over pinch rolls is carried again to the arc pole, during the arc pole, the cloth is tensile at width direction to detach the fold on the cloth, make follow-up shop cloth comparatively neat, improved shop cloth quality.

Preferably, the arc-shaped rod is detachably mounted on the swing piece through a limiting bolt.

Through adopting above-mentioned technical scheme for the arc pole can be dismantled removable, changes the arc pole of different radians according to the tensioning difference of different cloth, in order to satisfy the demand of different cloth.

Preferably, the connection assembly includes a star bolt mounted on the bracket and connected with the frame.

Through adopting above-mentioned technical scheme, the support passes through fixed subassembly to be installed in the frame, and on the one hand convenient to detach transports, and on the other hand can dismantle fast when not needing to use.

Preferably, the adjacent both sides limit of support has seted up the breach, coupling assembling still including install in the frame and block in the locating lever of breach.

Through adopting above-mentioned technical scheme, when the installing support, erect the breach of support on the locating lever earlier, it is fixed to screw up the star bolt again to reduce the time that the star bolt aimed at the hole on the frame and need only a star bolt just can the fixed bolster, reduce the ann and tear the time open.

Preferably, the support is provided with a plurality of lightening holes.

Through adopting above-mentioned technical scheme, reduced the dead weight of support for the staff is more laborsaving when installation, transport.

Preferably, the side wall of the swing piece and the end connected with the support is provided with an arc-shaped hanging hole, the support is far away from one end of the rack and is provided with a hanging bolt, and the swing piece is hung on the hanging bolt through the hanging hole.

By adopting the technical scheme, when the swing sheet and the arc-shaped rod are installed, the hanging hole of the swing sheet is aligned to the hanging bolt, and the hanging bolt is buckled into the hanging hole, so that the hanging of the swing sheet is realized. When the hanger is required to be taken down, the swinging piece is directly lifted, so that the hanging hole is separated from the hanging bolt, and the swinging piece can be taken down.

Preferably, the swing sheet is kept away from support one end is provided with the horizontal piece, horizontal piece length direction's both ends are provided with two gag lever posts, the arc pole is located the gag lever post with hang between the hole on the swing sheet, just the vertical projection on the crooked top of arc pole is two the gag lever post encloses the region in city outside.

Through adopting above-mentioned technical scheme, the transport route of restriction cloth for the cloth is great with the contact surface of arc pole, thereby improves the expansion effect of arc pole to the cloth.

Preferably, one end, far away from the rack, of the support is rotatably provided with a guide roller, and the height of the guide roller is lower than that of the arc-shaped rod.

Through adopting above-mentioned technical scheme for the cloth is through the exhibition of guide roll again after the expansion effect of arc pole, thereby smooth carry on the carry over pinch rolls.

To sum up, the utility model discloses a beneficial technological effect does:

1. the arrangement of the arc-shaped rods enables the cloth to be stretched in the width direction, so that wrinkles on the cloth are removed, subsequent cloth laying is relatively tidy, and the cloth laying quality is improved;

2. through the setting of breach, reduce the star bolt and aim at the time that the hole on the frame will take, and only need a star bolt just can the fixed bolster, reduce the ann and tear the time open.
