Trick plate spacing changer for double raschel machines

Abstract

The present invention is a device that can easily perform the work of changing and adjusting the distance between the needle groove plates, and can adjust the stroke of the knitting needles without changing the work, and has two rows of knitting needles (1a) (1b) in the front and rear , the front and rear needle groove plates (2a) (2b), the front and rear intermediate frames (4a) (4b), the front machine table (5a) and the rear machine table (5b) attached to the two knitting needle rows, the middle Frames (4a) (4b) respectively support knitting needle rows and needle groove plates, so that they can perform knitting actions; the front machine platform (5a) and the rear machine platform (5b) are erected and fixed to fix the intermediate frame as a front The front part machine table (5a) and the rear part machine table (5b) are away from and close to the moving mechanism in a straight line, and the threaded shaft (12) is provided. A left thread (12b) is provided on the other side of the table, and the front table (5a) and the rear table (5b) are moved in a straight line by the rotation of the threaded shaft (12), and the needle groove plate is adjusted. interval.

Description

technical field [0001] The invention relates to a device for changing the distance between needle groove plates in a double-needle bed Raschel warp knitting machine. Background technique [0002] In the past, in the double-needle bed Raschel warp knitting machine having two rows of knitting needles in the front and back, when changing the thickness of the knitted fabric, it is necessary to change the distance between the knitting needles in the front and back. The spacing of the front and rear needle guide plates supplied with the needles. [0003] As a device for changing the interval between the front and rear needle slot plates, the present applicant proposed and applied for Japanese Patent Laid-Open No. 2000-80545. In this device, an eccentric mechanism equipped with a locking mechanism is connected to one end of each connecting link. The connecting rods are connected to each support rod supporting the opposite needle-slot plates, and the lock is released when the inter...

Problems solved by technology

[0004] However, in the interval change of the needle groove plates by the device of the above proposal, since the needle groove plates are rotationally displaced around the shaft of the support rod, the front ends of the needle groove plates are displaced in the stroke direction with respect to the front ends of the knitting needles. produce only minor deviations

If this is placed, the knitting condition will be changed because of the change of the knitting condition during knitting, which will cause obstacles to knitting. Therefore, in order to correct this, it is necessary to adjust and change the knitting needle stroke after changing the distance between the needle groove plates, which makes the needle groove Complicated work to change the plate spacing
