Description

Technical Field

[0001] The utility model relates to the technical field of loom components, in particular to a thread passing device for a knitting machine used in textiles. Background Art

[0002] A loom, also known as a weaving machine or a spinning machine, is a mechanical device used to weave or spin yarn or other long and thin materials into fabrics. Its basic function is to form fabrics by interweaving two or more groups of yarns at right angles. It is one of the important equipment in the textile field. A thread passing device is usually provided near the thread supply end of the loom to assist in the transportation of yarn.

[0003] The existing thread-passing devices for looms have the following disadvantages when in use: the existing thread-passing devices for looms generally adopt thread-passing wheels or thread-passing hooks, which have single functionality and only have basic thread-passing and conducting functions. When yarn breaks during the operation of the loom, it is impossible to fix the yarn from the yarn supply end. Subsequent wiring requires manual search for the thread ends for wiring, which requires a lot of operation. For this reason, we propose a thread-passing device for a textile knitting machine. Utility Model Content

[0004] The main purpose of the present utility model is to provide a thread-passing device for a textile knitting machine. Through the thread-passing mechanism arranged on the surface of the mounting frame, it can not only guide the delivery of the yarn, but also quickly cut off the yarn at the yarn supply end when the yarn breaks, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A thread-passing device for a knitting machine for a textile, comprising a mounting frame and a thread-passing mechanism, wherein a thread-passing mechanism is provided on the surface of the mounting frame, and the thread-passing mechanism comprises a spool, a cross bar, a vertical bar, a rotating shaft, a mounting plate, a thread-passing wheel, a spring, a support rod, a connecting rod and a pressure plate, a spool for supporting the thread roll is provided on the top of the mounting frame, and a cross bar is detachably connected to the side of the mounting frame at a position corresponding to the spool, the cross bar is movably connected to the vertical bar at one end away from the mounting frame, and the end of the vertical bar is movably connected to the mounting plate through a rotating shaft, thread-passing wheels are installed on both sides of the top of the mounting plate, and a spring is obliquely installed between the bottom of the mounting plate and the surface of the vertical bar, one side of the vertical bar is fixedly connected to the support rod, and a connecting rod is obliquely installed on one side of the end of the mounting plate, and pressure plates corresponding in position are installed on the ends of the support rod and the connecting rod.

[0007] Furthermore, it also includes an adjusting mechanism, wherein the end of the cross bar is provided with an adjusting mechanism, and the adjusting mechanism includes a slide groove, a fixing plate, a screw groove and a nut, a slide groove is opened in the horizontal direction on one side of the surface of the mounting frame, one end of the cross bar is fixedly connected to a fixing plate inserted into the inside of the slide groove, and a screw groove is opened on the outer wall of the cross bar near one end of the fixing plate and is screwed with a nut through the screw groove; a slide groove structure is opened on the surface of the mounting frame when installing the cross bar, and the fixing plate at the end of the cross bar is aligned with the slide groove and inserted, and the cross bar is rotated after insertion so that it can fit into the inner wall position of the slide groove. At this time, the horizontal sliding adjustment of the cross bar can be carried out along the slide groove, and then the position of the line-passing device can be adjusted. After reaching the appropriate position, the nut is screwed along the screw groove until the nut is tightly attached to the slide groove surface, and is clamped on the surface of the mounting frame in cooperation with the fixing plate, thereby completing the fixation of the cross bar position, which is easy to use and flexible to adjust.

[0008] Furthermore, both ends of the surface of the mounting plate are provided with arc-shaped corners for facilitating thread passing; the arc-shaped corner structures on both sides of the mounting plate reduce wear on the yarn.

[0009] Furthermore, rubber pads for increasing friction are bonded to opposite sides of the pressure plate surface; when the pressure plate cooperates to clamp the yarn, the rubber pad structure on the surface can increase friction to better fix the yarn.

[0010] Furthermore, a screw hole is opened at one end of the cross bar away from the fixed plate, and an adjusting bolt is detachably connected between the screw holes, and the adjusting bolt passes through the end of the vertical bar; when the adjusting bolt is loosened, the angle of the vertical bar can be adjusted, and when the appropriate angle is reached, the adjusting bolt can be tightened to fix it.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the mounting frame is fixed to the wire feeding position of the knitting machine, and a spool structure is provided on its top to facilitate the insertion of the wire reel for wire feeding. The yarn first passes through the position between the pressure plates and then passes through the mounting plate. When passing through the top of the mounting plate, it fits the wire wheel and passes through and is connected to the wire feed end of the loom. When the loom is running to reel in the wire, the pressure of the yarn will press the mounting plate to tilt it around the rotating shaft, the spring will be stretched, and a gap will be generated between the pressure plates. The yarn will pass through the pressure plate and the wire wheel normally for transportation. When the yarn breaks during the weaving process of the loom, the pressure of the yarn on the top of the mounting plate is lost, and the spring elastic force drives the mounting plate to tilt toward the spring side. The pressure plate is immediately docked at the supply end to clamp the yarn, completing the fixation of the yarn supply end, facilitating subsequent wiring processing, and improving the functionality of the line-passing device; a slide groove structure is provided on the surface of the mounting frame. When installing the cross bar, the fixing plate at the end of the cross bar is aligned with the slide groove and inserted. After insertion, the cross bar is rotated so that it can fit to the inner wall position of the slide groove. At this time, the horizontal sliding adjustment of the cross bar can be carried out along the slide groove, and then the position of the line-passing device can be adjusted. After reaching the appropriate position, the nut is screwed along the screw groove until the nut is tightly attached to the slide groove surface, and clamped on the surface of the mounting frame with the fixing plate to complete the fixation of the cross bar position. It is easy to use and flexible to adjust. BRIEF DESCRIPTION OF THE DRAWINGS
