Description

Technical Field

[0001] This utility model relates to the field of warp knitting machines, specifically to a component in which guide needle combs and jacquard needle combs are interchangeable. Background Technology

[0002] In warp knitting machines, the main function of guide pins is to guide the warp yarns around the knitting needles and place them on the needles, ensuring that the warp yarns are arranged and interwoven regularly according to the requirements of the warp knitting structure, thus forming the basic structure of the fabric. Jacquard guide pins, in addition to having the same overall lateral movement function as ordinary guide pins, can also have each guide pin driven by the piezoelectric element of the warp knitting machine to perform an individual additional lateral movement. Through the superposition of these two lateral movements, complex patterns can be created on warp-knitted fabrics. In actual production, the two types of guide pins need to be configured according to requirements. In the existing structure, if it is necessary to replace the guide pins or Jacquard guide pins on the cradle, for example, by... The process involves replacing the yarn guide combs with Jacquard combs, or vice versa, to achieve different comb arrangements and adapt to various production needs. A common approach is to remove the old cradle and combs together, as the specifications and dimensions of the yarn guide combs and Jacquard combs differ. New mounting holes are then made on the new cradle to accommodate the new comb arrangement. Finally, the new yarn guide combs and Jacquard combs are installed on the new cradle. This entire process is time-consuming and involves significant downtime. Furthermore, each process requires the fabrication of a new cradle, followed by extensive debugging. The cost of replacing parts and debugging is high. Therefore, this case arises from this consideration. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a component in which the yarn guide needle comb and the Jacquard needle comb are interchangeable, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an interchangeable component of a yarn guide comb and a Jacquard comb, comprising a cradle, a yarn guide comb, and a Jacquard comb, wherein the yarn guide comb and the Jacquard comb are distributed in a fan shape on the cradle, and both the yarn guide comb and the Jacquard comb are provided with positioning holes for positioning and installation on the cradle, and the positioning holes of the yarn guide comb and the Jacquard comb are consistent with the position of the needles.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As shown in the figure, the interchangeable components of the yarn guide comb and Jacquard comb of this utility model include a rocker arm 1, a yarn guide comb 2, and a Jacquard comb 3. The yarn guide comb 2 and the Jacquard comb 3 are arranged in a fan shape on the rocker arm 1. Both the yarn guide comb 2 and the Jacquard comb 3 are provided with positioning holes 10 for positioning and installation on the rocker arm 1. The positioning holes 10 of the yarn guide comb 2 and the Jacquard comb 3 are consistent with the position of the needle. The yarn guide bar 2 and the jacquard bar 3 have perfectly overlapping positioning holes 10. When the yarn guide bar 2 and the jacquard bar 3 are projected onto each other, their respective needle tips and holes also overlap. The outer contour of the yarn guide bar 2 will not exceed the outer contour of the jacquard bar 3, thus ensuring that the yarn guide bar 2 and the jacquard bar 3 can be directly replaced at any position on the cradle 1 without interference. When different guide bars need to be replaced, the old guide bar can be directly removed and the new guide bar quickly replaced without replacing the entire cradle 1 and guide bars. After replacing the new guide bar, only a short adjustment period is needed before production can begin, greatly improving production efficiency and reducing production costs. Figure 6 In the arrangement shown, the four combs on the outside are yarn guide combs 2, and the four combs on the inside are jacquard combs 3. When necessary, the combs in any position can be replaced with other different types of combs.

[0022] like Figure 1 and 2 The yarn guide comb 2 includes a yarn guide bracket 21 and a yarn guide needle 22, and the Jacquard comb 3 includes a Jacquard bracket 31 and a Jacquard needle 32. The positioning hole 10 is provided on the yarn guide bracket 21 and the Jacquard bracket 31.

[0023] In a preferred embodiment, both the yarn guide hanger 21 and the jacquard hanger 31 have two positioning holes 10.

[0024] like Figure 3The cradle 1 has a hanger mounting bracket 11, which has hanger mounting holes 20 that match the positioning holes 10 of the yarn guide comb 2 and the Jacquard comb 3. The positioning holes 10 of the yarn guide comb 2 and the Jacquard comb 3 and the hanger mounting holes 20 of the hanger mounting bracket 11 are connected by connectors, thereby fixing the yarn guide comb 2 and the Jacquard comb 3 to the cradle 1.

[0025] like Figure 4 The cradle 1 has a threaded mounting hole 30, and the hanger mounting bracket 11 has a strip-shaped through hole 40 that matches the threaded mounting hole 30 of the cradle 1. Threaded fasteners pass through the strip-shaped through hole 40 of the hanger mounting bracket 11 and are fastened to the threaded mounting hole 30 of the cradle 1. The position of the hanger mounting bracket 11 can be adjusted through the strip-shaped through hole 40.

[0026] In a preferred embodiment, the number of strip-shaped through holes 40 is two.

[0027] like Figure 1 The guide bar 2 also includes an adapter support 23 and a guide needle seat 24. The guide needle 22 is mounted on the guide needle seat 24. One end of the adapter support 23 is connected to the guide hanger 21 by fasteners, and the other end is connected to the guide needle seat 24 by fasteners. The function of the adapter support 23 is to form a bend and make room, guiding the position of the guide needle 22 to match the position of the Jacquard needle 32, ensuring consistency in replacement, and avoiding interference between the guide bars during installation.

[0028] The adapter support 23 has a threaded hole at the top and a through hole at the bottom. The yarn guide hanger 21 has a through hole at the bottom that matches the threaded hole of the adapter support 23. The yarn guide needle seat 24 has a threaded hole at the top that matches the through hole of the adapter support 23. Threaded fasteners pass through the through hole and the threaded hole to fix the yarn guide hanger 21, the adapter support 23 and the yarn guide needle seat 24.

[0029] like Figure 2 The Jacquard comb 3 also includes a Jacquard needle holder 33, on which Jacquard needles 32 are mounted. The Jacquard needle holder 33 is connected to the Jacquard hanger 31 by fasteners. Furthermore, the holes on the yarn guide hanger 21 for connecting the adapter support 23 correspond to the holes on the Jacquard hanger 31 for connecting the Jacquard needle holder 33. If necessary, the adapter support 23 and the yarn guide needle holder 24, or the Jacquard needle holder 33, can be replaced individually to achieve the purpose of replacement.

[0030] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
