Xinda Textile machinery accessories provide a variety of leaf springs for shuttle looms, textile springs, loom springs, including traditional loom leaf spring accessories F49(check strap spring). The length of the textile machine apron spring F49 is 95mm, the thickness is 2.5mm, and the length of the middle square hole is 11.5cm. The material of the textile leaf spring is 60Si2MnA. Each loom uses 4 F49 leaf springs, each string has 20 pieces, and the weight is about 1.3KG.
The F49 leaf spring used in traditional looms is an arc-shaped pressing plate on the outer side of the textile apron, with a width of 37mm. It is mainly used to ensure that the apron moves forward and backward in the sliding box and applies force. In the process of high-speed reciprocating shuttle throwing, the recovery and prevention of shuttle energy need to rely on the friction of leaf spring and sliding box. Textile spring depends on the torsion and tension of the spring itself, and the dual parts can be restored to the original position. The overall design meets the requirements of repeated anti fatigue cycle in mechanical movement.
When assembling the F49 (check strap spring) on the old traditional loom, it is necessary to pay attention that the square neck of the apron nut should be embedded into the square hole of the apron spring to prevent loosening. Then pull the BUFFER back and forth with two fingers, and the movement distance should not be less than 25 mm. The tightness of the apron can be adjusted by changing the in and out position of the apron nut F52. In addition, the elasticity of both sides of the apron spring F48 should be consistent, and it should not rub with the apron bottom plate (F44, 3351, 3352, 2681, 2682) and the BUFFER guide plate.
