When cloth pressing operation is needed, firstly, the driving piece 1 and the driving device 17 start to operate, the hemming and spreading device 2 and the cloth pressing rod 8 operate, then the cloth pressing rod 8 is driven by the lifting motor 3 to move towards the direction close to the sliding plate 19, namely, when cloth is put, the cloth pressing rod 8 is located at the position close to the sliding plate 19, so that the cloth pressing rod 8 is utilized to press the fabric to the hemming and spreading device 2, and two sides of the fabric are hemmed and spread by the hemming and spreading device 2.
When cloth cutting and non-cloth movement are required, the cloth pressing rod 8 is driven to move towards the direction far away from the curling and unfolding device 2 through the movement of the lifting motor 3, namely the cloth pressing rod 8 is lifted to the highest position, and the cloth pressing rod 8 is not contacted with the fabric; after the cloth pressing rod 8 rises to the highest position, the cloth pressing motor 14 starts to operate, the cloth pressing motor 14 drives the shifting fork 15 to move, the cloth pressing shaft 11 drives the cloth pressing strips 13 to move, the fabric is tightly pressed on the surface of the sliding plate 19, the fabric is cut by the cutter, and the cloth laying of the fabric layer is finished, and the next layer of cloth laying is continued.
It can be seen that the cloth paving machine actively spreads the fabric on the surface of the hemming-spreading device 2 through the cloth pressing rod 8, so that the fabric can slide downwards along the hemming-spreading device 2, and the fabric is paved on the table board; meanwhile, the cloth pressing rod 8 can continuously rotate, so that the fabric can be continuously transmitted conveniently; it can be seen that the fabric is in close contact with the hemming-unfolding device 2, the hemming-unfolding effect can be improved, and the hemming-unfolding device 2 is stable in operation, low in noise, adjustable in speed and good in unfolding effect; meanwhile, as the hemming-unfolding device 2 is positioned at the bottom of the sliding plate 19, namely at the lower cloth port, the fabric is laid on the table board at the first time after being unfolded, and the rewinding probability is low; when cloth needs to be cut, the cloth pressing strips 13 press the fabric onto the sliding plate from top to bottom, and the cloth pressing firmness is high.
It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The cloth spreading machine provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
