[0038] The present invention is an invention made by the inventor based on the following facts.

[0039] Figure 1 A warp knitting machine hanger structure in the prior art is shown.

[0040] like Figure 1 As shown, the existing warp knitting machine hanger consists of a fixed steel sleeve, a hanger, a hanger shaft, a ball rack and its accessories, which has the following disadvantages: (1) the ball rack needs to be oiled frequently; (2) after oiling, the lubricating oil will drip down during the transverse movement of the comb bar, contaminating the fabric surface; (3) the travel of the hanger shaft is short and the pattern width is limited; (4) when the hanger moves, the steel balls in the ball rack will rotate together, which is sliding friction and has large resistance.

[0041] Based on this, the inventors of this application, after long-term creative work, have come up with the following inventions.

[0042] The comb hanger 100 according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] like Figures 2 to 12 As shown, the comb bar hanger 100 according to the embodiment of the present invention comprises: a mounting frame 10 and a comb bar hanger body 20 .

[0044] Specifically, the mounting frame 10 extends in the horizontal direction, and a first fitting piece 11 is provided on the mounting frame 10 along its length direction. A second fitting piece 21 corresponding to the first fitting piece 11 is provided on the comb hanger body 20, and the second fitting piece 21 is rollingly connected to the first fitting piece 11 so that the comb hanger body 20 can move horizontally on the mounting frame 10.

[0045] In other words, the comb hanger 100 according to the embodiment of the present invention is mainly composed of a mounting frame 10 and a comb hanger body 20, the mounting frame 10 extends in a substantially horizontal direction, a first mating piece 11 is provided in the length direction of the mounting frame 10, and a second mating piece 21 is provided on the comb hanger body 20. The first mating piece 11 and the second mating piece 21 can be connected in a rolling manner, that is, when the comb hanger body 20 is moved, the friction between the first mating piece 11 and the second mating piece 21 is rolling friction.

[0046] Therefore, the comb hanger 100 according to the embodiment of the present invention adopts the combination of the mounting frame 10 and the comb hanger body 20, and the mounting frame 10 and the comb hanger body 20 adopt rolling friction, which not only has the advantages of small friction coefficient, small resistance, and high speed, but also does not need to be refueled, eliminating the hidden danger of lubricating oil contaminating the cloth surface. In addition, compared with the comb hanger structure of the prior art, it also has the advantages of reducing the load of the traverse component (comb hanger body 20) and reducing the failure rate.

[0047] like Figure 3 As shown, according to one embodiment of the present invention, the comb hanger body 20 is located on one side of the mounting frame 10, and a second matching piece 21 is provided on one side of the comb hanger body 20 adjacent to the mounting frame 10, thereby improving the installation efficiency of the comb hanger body 20.

[0048] like Figure 4 and Figure 5 As shown, further, the mounting frame 10 is formed into a long strip, the number of the first matching pieces 11 is more than 2, the number of the second matching pieces 21 corresponds to the number of the first matching pieces 11, one first matching piece 11 is arranged on the upper top surface 12 of the mounting frame 10 along its length direction, and another first matching piece 11 is arranged on the lower bottom surface 13 of the mounting frame 10 along its length direction, that is, the first matching pieces 11 are respectively arranged on the upper end surface 12 and the lower bottom surface 13 of the long strip mounting frame 10, which can improve the lateral movement rate of the comb hanger body 20 and improve the stability during the lateral movement. It should be noted that, since the second matching piece 21 corresponds to the first matching piece 11, one second matching piece 21 is located above the mounting frame 10 and matches with the first matching piece 11 on the upper top surface 12, and the other second matching piece 21 is located below the mounting frame 10 and matches with the first matching piece 11 on the lower bottom surface 13.

[0049] like Figure 1and Figure 4 As shown, optionally, the first matching member 11 is formed as a guide rail, which can be a guide column structure, such as Figure 3 , Figure 8 and Fig. 9 As shown, the second matching piece 21 is formed as a rolling bearing. When installing, the rolling bearing can be installed on the guide rail. The outer peripheral surface of the rolling bearing is provided with an annular groove, and at least a part of the guide rail is inserted into the annular groove.

[0050] like Figure 3 , Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, a side of the comb hanger body 20 adjacent to the mounting frame 10 is provided with an inwardly recessed groove 26, and at least a portion of the mounting frame 10 along its width direction is inserted into the groove 26, that is, when the mounting frame 10 is installed, the comb hanger body 20 can be installed in the groove 26, and the groove 26 can play a certain degree of avoidance role for the comb hanger body 20, thereby improving the compactness of the structure.

[0051] According to one embodiment of the present invention, a mounting through hole 22 is provided on the comb hanger body 20, one end of the second fitting 21 is inserted into the mounting through hole 22, and the other end of the second fitting 21 is rollingly connected to the first fitting 11, that is, the second fitting 21 can be installed by setting the mounting through hole 22, so that the protruding length of the other end of the second fitting 21 can be controlled conveniently.

[0052] like Figure 3 , Figures 8 to 10 As shown, further, the second matching member 21 includes a mounting portion 23 and a rolling portion 24. The mounting portion 23 is formed as a columnar member. One end of the mounting portion 23 is inserted into the mounting through hole 22, and the other end of the mounting portion 23 is located above or below the mounting frame 10. The rolling portion 24 is sleeved on the other end of the mounting portion 23. The rolling portion 24 can rotate around the axial direction of the mounting portion 23 and cooperate with the first matching member 11. The specific cooperation method can be determined according to the specific structure. For example, when a slide groove is provided on the outer peripheral surface of the rolling portion 24, a slide rail is formed on the first matching member 11.

[0053] like Figure 3 , Fig.11 and Fig.12 As shown, optionally, the second matching piece 21 corresponding to the upper top surface 12 further includes an eccentric adjustment block 25, which is disposed in the mounting through hole 22 and sleeved on one end of the mounting portion 23. The eccentric adjustment block 25 can be used to adjust the distance between the two second matching pieces 21 corresponding to the upper top surface 12 and the lower bottom surface 13. One end of the mounting portion 23 can be fixed by the eccentric adjustment block 25.

[0054] Furthermore, there are two second matching pieces 21 corresponding to the upper top surface 12 and the lower bottom surface 13 , respectively. An eccentric adjustment block 25 is provided in each of the two second matching pieces 21 of the upper top surface 12 , which can improve the structural stability.

[0055] In summary, the comb hanger 100 according to the embodiment of the present invention adopts the combination of the mounting frame 10 and the comb hanger body 20, which has at least the following advantages:

[0056] (1) No need to add oil, eliminating the hidden danger of lubricating oil contaminating the fabric surface.

[0057] (2) The distance between the second matching pieces 21 on the upper and lower sides of the comb bar hanger body 20 can be adjusted, which is helpful to eliminate the gap during movement.

[0058] (3) The comb hanger body 20 and the mounting frame 10 move relative to each other through the bearing (the second matching part 21) and the guide column (the first matching part 11), which belongs to rolling friction, has a small friction coefficient and resistance, and is conducive to high speed.

[0059] (4) Reduce the load on the traverse component (comb hanger body 20) and reduce the failure rate.

[0060] (5) The comb hanger body 20 can be long or short and is not affected by the pattern width.
