AI Technical Summary
The existing transverse rake needle mechanism has needles pointing upwards, which makes it easy for yarn to leak when it moves out.
A novel lateral shifting rake needle mechanism is designed, which uses a servo motor to drive the lateral shifting rake needle plate. The rake needle is a curved needle body, and is driven by a linear guide rail and a lead screw. After the yarn moves laterally in the curved area, it smoothly slides into the chain needle block, avoiding yarn leakage.
It effectively solves the problem of unstable yarn weft laying, ensuring that the yarn slides smoothly into the chain needle block, thus improving the stability and quality of knitting loops.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to weaving technology field, concretely is a new side shift harrow needle mechanism. BACKGROUND
[0002] The knitting needle is made of steel wire or steel band through mechanical processing, is used for weaving yarn into loop and makes loop string connection into knitted fabric, and the structure and shape of the knitting needle influence the knitting process, the productivity of the knitting machine and the quality of the product, and are the important basis for the design of the knitting machine. The commonly used knitting needle has three kinds of tongue needle, hook needle and composite needle.
[0003] The needle tip of the original horizontal shift harrow needle mechanism in the prior art is upward, is used for hooking yarn to realize horizontal shift, and the "A" area of the needle tip is easy to cause local yarn missing when the yarn is moved out of the harrow needle and hung into the weft yarn conveying needle block. UTILITY MODEL CONTENT
[0004] The utility model aims at providing a new side shift harrow needle mechanism to solve the problems in the above background technology.
[0005] In order to achieve the above object, the utility model provides the following technical scheme: a new side shift harrow needle mechanism, including installation bottom plate, one side of the installation bottom plate is fixedly provided with servo motor, the output end of the servo motor is connected with speed reducer, one end of the speed reducer is connected with lead screw, the sliding block on the lead screw is fixedly connected with link plate, one side of the link plate is connected with side shift harrow needle plate, the installation bottom plate is equipped with linear guide rail below the link plate, the side of the side shift harrow needle plate away from the link plate is fixedly provided with a plurality of harrow needles.
[0006] Preferably, the harrow needle is a needle body with a bending angle.
[0007] Preferably, a plurality of positioning holes are arranged on the side shift harrow needle plate.
[0008] Preferably, a sliding groove is arranged on the lower surface of the upper support cover and the upper surface of the lower base.
[0009] Compared with the prior art, the utility model has the beneficial effects that the originally upward needle head is changed into downward, so that when the yarn starts to horizontally shift after entering the harrow needle area, the yarn is limited in the bending area by the needle tip, and after completing horizontal shift, the yarn will slide into the chain needle block along the needle tip, and the yarn missing scene will not appear, thereby the problem of unstable weft laying is well solved.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0016] Please refer to 1-4. One embodiment of this utility model is a novel lateral shifting rake needle mechanism. This application is an improvement based on a high-speed multi-angle weft laying mechanism with patent number 2024109251757. It includes a mounting base plate 1, a servo motor 2 fixedly mounted on one side of the mounting base plate 1, a reducer 3 connected to the output end of the servo motor 2, a lead screw 4 connected to one end of the reducer 3, a connecting plate 5 fixedly connected to a slider on the lead screw 4, a lateral shifting rake needle plate 6 connected to one side of the connecting plate 5, a linear guide rail 8 located below the connecting plate 5 on the mounting base plate 1, and several rake needles fixedly mounted on the side of the lateral shifting rake needle plate 6 away from the connecting plate 5. 7; The lateral shifting rake needle mechanism consists of the lateral shifting rake needle plate 6 of the rake needle 7, a linear guide rail 8, a lead screw 4, a reducer 3, and a servo motor 2. The lateral shifting rake needle plate 6 moves under the drive of the servo motor 2 and is transmitted through the lead screw 4. The lateral shifting rake needle plate 6 mainly moves the yarn pressed into the rake needle 7 by the yarn pressing plate through the weft laying carriage and the lateral shifting rake needle mechanism synchronously for a distance, so that the yarn is wrapped around the chain needle block. The rake needle 7 is a needle body with a bending angle. The yarn is restricted in the bending area by the needle tip of the rake needle 7. After the lateral shift is completed, the yarn will slide into the chain needle block along the needle tip. The lateral shifting rake needle plate 6 is provided with several positioning holes to facilitate the position adjustment of the lateral shifting rake needle plate 6.
