Abstract

A chain transmission tensioning mechanism of a shaping tenter belongs to the after-finish machinery technology field of non-woven products. The mechanism comprises a chain wheel, a sliding seat and a tensioning, wherein, the chain wheel is rotationally arranged on the sliding seat through a central shaft; the sliding seat is connected with the tensioning device; and the sliding seat and the tensioning device are in sliding fit on a machine head. The mechanism is characterized in that the tensioning device comprises an acting cylinder and an ejector rod; the cylinder body of the action cylinder is fixed on the machine head of the tentering and forming machine; the cylinder column of the acting cylinder is matched with one end of the ejector rod; and the other end of the ejector rod is fixed with the sliding seat. The mechanism has the advantages that the acting cylinder is adopted to realize tension control instead of adopting a spring to realize tension control on the tension device in the prior art, therefore, constant tension control can be realized for chain transmission, so as to allow the chain transmission to be balanced, and ensure that the shaped non-woven fabrics have the consistent shaping effect.

Description

technical field

[0001] The invention belongs to the technical field of finishing machinery for nonwoven products, and in particular relates to a chain transmission tension adjustment mechanism of a tenter setting machine. Background technique

[0002] The working principle of the stenter setting machine is to drive the main drive shaft to move through the transmission mechanism, and the main drive shaft drives two sets of horizontally driven chains through two sets of gears or worm boxes. The chains are equipped with needle plates arranged with needles. When in use, the selvedges on both sides of the nonwoven fabric are fixed with the needles on the needle plate, and the nonwoven fabric is moved through the circular movement of the transmission chain, and the nonwoven fabric is dried and shaped by the hot air circulation heating device of the heating body.

[0003] As is well known in the industry, during the process of hot air stenter setting, the transmission chain will be...
