Description

Technical Field

[0001] The utility model relates to a yarn lubrication structure of a warp knitting machine, belonging to the technical field of warp knitting machines. Background Art

[0002] A warp knitting machine forms a knitted fabric based on warp yarns (longitudinal yarns) through a group or several groups of parallel arranged knitting needles. Since the friction coefficient between fibers is reduced after the lubricating oil adsorbs on the fiber surface to achieve the effects of soft, smooth hand feeling and comfortable wearing, it is a common process to lubricate the yarn with lubricating oil. The yarn is passed between two round rollers in an oil storage box, and an oil absorption layer is wrapped on the round roller. The round roller rotates driven by a motor, and the oil absorption layer adsorbed with lubricating oil lubricates the yarn passing between the two round rollers. To improve efficiency, multiple yarns need to pass between the two round rollers simultaneously. When the yarn passing between the two round rollers is slack, since the distance between adjacent two yarns is small, there is a situation where the yarns are entangled with each other. Therefore, it is necessary to design a yarn lubrication structure of a warp knitting machine to prevent the yarns from being entangled with each other when slack. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a yarn lubrication structure of a warp knitting machine to solve the problems put forward in the above background art. The utility model prevents the yarns from being entangled with each other when slack.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A yarn lubrication structure of a warp knitting machine includes an oil storage box. The cross-section of the oil storage box is a trapezoid with a wider upper part and a narrower lower part. A lower round roller driven by a motor is rotatably installed in the oil storage box. An upper round roller parallel to the lower round roller is arranged above the lower round roller. Both ends of the upper round roller are rotatably installed with support plates, and the support plates are fixedly connected to the oil storage box. A lower oil absorption layer fixedly connected to the lower round roller is sleeved on the lower round roller. An upper oil absorption layer fixedly connected to the upper round roller is sleeved on the upper round roller. A plurality of convex ring parts arranged along the length direction of the upper round roller are evenly installed on the outer surface of the upper oil absorption layer. A plurality of annular grooves arranged along the length direction of the lower round roller are evenly opened on the outer surface of the lower oil absorption layer. The plurality of convex ring parts are respectively inserted into the plurality of annular grooves.

[0005] Further, an oil drain valve is installed at the bottom of the oil storage box, and the oil drain valve communicates with the internal space of the oil storage box.

[0006] Further, bottom plates are fixedly connected to the lower edges of the two inclined surfaces of the oil storage box respectively. Two fixing holes for inserting screws are opened on the upper surface of the bottom plates.

[0007] Further, a supporting plate for restricting the position of the screw head is provided on the upper side of the bottom plate. The supporting plate is arranged parallel to the bottom plate and is fixedly connected to the oil storage box. There is a gap between the supporting plate and the bottom plate. Two small holes for inserting the screws are formed on the upper surface of the supporting plate, and the small holes are aligned with the fixing holes.

[0008] Further, a plurality of first strip-shaped openings are uniformly formed on the upper surface of the bottom plate, and a plurality of second strip-shaped openings are uniformly formed on the upper surface of the supporting plate.

[0009] Further, magic tape hook surfaces are installed on the outer surfaces of both ends of the upper round roller and the outer surfaces of both ends of the lower round roller, and magic tape loop surfaces are installed on the inner surfaces of both ends of the upper oil absorption layer and the inner surfaces of both ends of the lower oil absorption layer. The magic tape hook surfaces are adhered to the magic tape loop surfaces.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Enable multiple yarns to pass through between the upper oil absorption layer and the lower oil absorption layer. Then, during the rotation of the upper round roller and the lower round roller driven by the motor, the lubricating oil in the oil storage box is transferred to the yarns by the lower oil absorption layer and the upper oil absorption layer, realizing the lubrication of the yarns.

[0012] 2. When the yarn passes through between the upper oil absorption layer and the lower oil absorption layer, make the yarn be located between two adjacent convex ring parts. Since the multiple convex ring parts on the upper oil absorption layer are respectively inserted into the multiple annular grooves on the lower oil absorption layer, the multiple yarns passing between the upper round roller and the lower round roller are isolated under the cooperation of the convex ring parts and the annular grooves. When a certain yarn in the yarns is slack, it will not be randomly wound around its adjacent yarns, realizing the prevention of the yarns from being wound around each other when slack.

[0013] 3. When installing the oil storage box on the support carrier by using screws, make the screws sequentially penetrate the small holes on the supporting plate and the fixing holes on the bottom plate. Then, under the limitation of the supporting plate, there is a gap between the screw head and the bottom plate. When the screw cannot be screwed by conventional means, the oil storage box can be smoothly removed by cutting off the screw by using the gap between the supporting plate and the bottom plate.
