Description

Automatic cloth unloading method and device for scutching cloth rolling machine

Technical Field

The invention relates to the technical field of knitting, in particular to an automatic cloth unloading method and device for an open width cloth rolling machine.

Background

In weaving the operation flow, knitting machine weaves and accomplishes the back, must draw the cloth and send to a batching machine, utilize this batching machine with the cloth roll-up to a batching roller on, take out the batching roller after the batching is accomplished again, but prior art's batching machine needs artifical manual opening baffle just can roll it on the cropping rail when the batching roller has rolled up the cloth, and because the batching roller weight after the batching is accomplished is not light, the baffle that very easily leads to long-term work on the one hand is difficult to effectively block the batching roller after the batching is accomplished, on the other hand manual switch baffle has certain potential safety hazard to personnel's personal safety, the batching flow is too hard and time-consuming. Therefore, the cloth pushing device of the cloth rolling machine should be transported out, as shown in the Chinese patent document: CN201922033298.7 discloses a novel cloth pushing device suitable for cloth rewinder, its structure includes: the extension board, the transition roller, the cropping rail, the cloth roller, the lower rail, the cloth pushing device, the extension board sets up in transition roller one side top, the transition roller is connected with the cloth roller transmission, the cloth roller is installed on the lower rail, through the motor circular telegram work on the cloth pushing device, drive sprocket just takes place mechanical rotation, driven sprocket follows the rotation under the effect of belt, make propulsion plate anticlockwise rotation, rotatory in-process, push away the connecting block toward one side under the effect of inserted bar, cause the baffle to be pushed away toward one side by the connecting block, this cloth rolling machine can take propulsion plate anticlockwise rotation through motor circular telegram area, make the connecting block push away the baffle toward one side, thereby the cloth roller on lower rail top just loses spacing and breaks away from the lower rail, finally roll to on the cropping rail. But it needs the whole occupation space of cropping rail big, and it is to push out the cloth roller by force and can push out after needing cloth roller batching to accomplish, if the cloth roller does not accomplish the batching of whole roll of cloth then the roll diameter can't be pushed out by the automation greatly, has the problem that can't unload the cloth when the roll diameter of cloth roller does not reach, still has when rolling off the cloth roller because the effort of pushing out to have certain potential safety hazard to staff's personal safety with the cloth roller pushing down to the cropping rail simultaneously.
