Description

Technical Field

[0001] The utility model relates to the technical field of double-sided circular knitting machines, in particular to a combined yarn mouth rod for a double-sided circular knitting machine. Background Art

[0002] The double-sided circular knitting machine has developed rapidly because of its multiple loop forming systems (also known as the number of yarn feeding paths or the number of loop forming paths, referred to as the number of paths), high speed, high output, fast pattern change, good fabric quality, fewer processes and strong product adaptability; the yarn feeder, also known as the steel shuttle or yarn guide or yarn feeder rod, is installed on the knitting machine to feed the yarn directly to the knitting needles.

[0003] When the double-sided circular knitting machine is working, the old coil needle hook is withdrawn and the needle tongue is opened. When the old coil withdraws from the needle tongue, the yarn mouth needs to be protected to prevent rebound closure and failure to hook the new yarn loop to cause missed stitches. Different yarn mouth widths are required for needle protection for different sizes and routes during knitting. In the prior art, the yarn feed mouth is usually an integrated structure. For example, patent CN210134219U discloses a new yarn feed mouth with a single yarn feed mouth body. The yarn feed mouth body is provided with a claw hook for preventing the cut knitting thread from escaping from the thread outlet guide groove, which can improve the knitting yield rate. However, it is not convenient to use in knitting operations of different sizes and routes, and sand mouths of different specifications need to be prepared for replacement, which is not conducive to reducing the types of yarn mouths and yarn mouth inventory. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned defects or problems existing in the background technology and provide a combined yarn mouth rod for a double-sided circular knitting machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The invention discloses a combined yarn mouth rod for a double-sided circular knitting machine, comprising a yarn mouth body, a fixing hole is arranged on the upper part of the yarn mouth body, the yarn mouth body is installed on the double-sided circular knitting machine through the fixing hole, the yarn mouth body is installed with a split component through a fastener, mounting holes are arranged on the lower part of the yarn mouth body and the split component corresponding to the fasteners, any mounting hole is arranged as a long waist hole, an mounting gap is arranged between the split component and the yarn mouth body, and the mounting gap is adjusted at the mounting position of the long waist hole by the fastener.

[0007] In some embodiments of the present invention, the yarn mouth body is provided with a mounting recess for facilitating mounting of the split component, and the bottom surface of the split component abuts against the mounting recess.

[0008] In some embodiments of the utility model, a side of the split component away from the yarn mouth body is inclinedly provided with an inclined portion.

[0009] In some embodiments of the present invention, the inclination angle formed between the two ends of the inclined portion is set to 30-60°.

[0010] In some embodiments of the present invention, the cross section of the inclined portion is an arc-shaped convexity, a trapezoid, or a triangle.

[0011] In certain embodiments of the utility model, the long waist hole is configured as a tapered waist hole, and a first angle is formed between two side edges of the tapered waist hole.

[0012] In some embodiments of the present invention, the fastener includes a positioning screw, and the other mounting hole is configured as a matching hole corresponding to the positioning screw.

[0013] In certain embodiments of the utility model, the fixing hole is in the shape of an elongated strip, and is arranged along the length direction of the yarn mouth body. A second through hole is arranged on the upper part of the yarn mouth body, and the second through hole is arranged below the fixing hole. The second through hole makes it more secure when installed on a knitting double-sided circular machine, and is not prone to deflection or shaking.

[0014] In some embodiments of the present invention, a first yarn feeding hole and a second yarn feeding hole are arranged at the lower part of the yarn mouth body.

[0015] In certain embodiments of the present invention, the first yarn feeding hole and the second yarn feeding hole are used for different yarns to pass through, and a yarn adjustment avoidance position is recessed on the front side of the yarn mouth body along the yarn adjustment direction.

[0016] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. An installation gap is set between the split component and the yarn mouth body. The installation gap is adjusted at the installation position of the long waist hole through fasteners. Different installation gaps enable the yarn mouth to obtain different needle guard widths, so that it can be suitable for different inch numbers and routes, and is easy to install on different knitting double-sided large circular machines. There is no need to prepare yarn mouths of various specifications due to different inch numbers and routes, which helps to reduce the types of yarn mouths, reduce inventory, and reduce costs;

[0018] 2. The second through hole cooperates with the fixing hole, so that the yarn mouth body is more firmly installed on the double-sided circular knitting machine, and the yarn mouth body is not prone to deflection or shaking;

[0019] 3. Setting the inclined part and the line adjustment avoidance position will help to feed the yarn smoothly and ensure the normal operation of the knitting double-sided circular knitting machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] As an embodiment, the fixing hole 10 is in the shape of an elongated strip, and the fixing hole 10 is arranged along the length direction of the yarn mouth body 1. A second through hole 11 is arranged on the upper part of the yarn mouth body 1, and the second through hole 11 is arranged below the fixing hole 10. The second through hole 11 cooperates with the fixing hole 10, so that the yarn mouth body 1 is installed on the knitting double-sided circular machine more firmly, and the yarn mouth body 1 is not prone to deflection or shaking.

[0034] As an implementation mode, the yarn mouth body 1 is in an "L" shape.

[0035] The yarn mouth body 1 is installed with a split component 2 through a fastener.

Further, the inclined angle α2 formed between the two ends of the inclined portion 20 is set to 30-60°; preferably, the inclined angle formed between the two ends of the inclined portion 20 is set to 45°.

[0043] As an implementation mode, the two ends of the inclined portion 20 are straight or concave inward to form a curve, which helps to smoothly feed the yarn.

[0044] The cross section of the inclined portion 20 is an arc-shaped protrusion or a trapezoid or a triangle, which is helpful for smooth yarn feeding; specifically, the arc-shaped protrusion includes a symmetrical semicircle, a semi-ellipse or an asymmetrical arc, and different arc-shaped protrusion shapes are suitable for different yarn feeding requirements. The trapezoid includes a right-angled trapezoid and an isosceles trapezoid, and the triangle includes a right-angled triangle, an isosceles triangle or a non-isosceles acute triangle.
