Description

Technical Field

[0001] This utility model relates to the field of knitting flat knitting machine technology, specifically to a top-mounted roller structure for a computer-controlled knitting flat knitting machine. Background Technology

[0002] A computerized flat knitting machine is a double-needle plate needle weft knitting machine. Its cam mechanism acts like a set of planar cams; the needle feet enter the grooves of the cams, and by moving the cams, the needles are forced to move up and down rhythmically within the needle grooves of the needle plate. Through the action of the needle hook and the needle tongue, the yarn is knitted into fabric. The roller mechanism is an important component of the computerized flat knitting machine, used for taking and pulling the fabric.

[0003] Chinese Patent Application No. CN202321154389.6 discloses a roller device for a computerized flat knitting machine, relating to the field of computerized flat knitting machines. The device includes a base with support frames symmetrically fixed to both sides of the top of the base. Fixed rollers are installed on the bottom of opposite sides of the two support frames. This device can adjust the spacing between the rollers. However, in practical use, when the knitting material is transported through the rollers, its transport position needs to be at the center of the roller structure for convenient subsequent knitting. This device, however, adjusts the roller spacing by moving one set of rollers while keeping the other fixed, causing the center position to change, thus affecting the transport position and hindering subsequent processing.

[0004] Based on this, this utility model designs an upper roller structure for a computer-controlled flat knitting machine to solve the above problems. Utility Model Content

Under the threaded engagement of the screw 4 and the slide plate 3, the two sets of slide plates 3 are driven to move on the slide rail 2, so that the two sets of rollers 9 move synchronously close to each other or far apart. During the process, the distance is controlled by the cooperation of the red light rangefinder 10 and the range measuring plate 11. When the spacing of the rollers 9 is adjusted according to actual needs, the center position of the two sets of rollers 9 remains unchanged, which facilitates the conveying of the woven material.

[0028] In this embodiment of the invention, a slide rail 2, a slide plate 3, a screw 4, and a servo motor 5 are provided. The servo motor 5 drives the screw 4 to rotate. Under the threaded engagement of the screw 4 and the slide plate 3, the two sets of slide plates 3 move on the slide rail 2, thereby enabling the two sets of rollers 9 to move synchronously close to or far apart. When the spacing of the rollers 9 is adjusted according to actual needs, the center position of the two sets of rollers 9 remains unchanged, which facilitates the conveying of the woven material. By providing a red light rangefinder 10 and a distance measuring plate 11, the distance is controlled when the rollers 9 move.
