[0026] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0027] Example 1.
[0028] like Figures 1-4 As shown, the adjustable gap device of the computer flat knitting machine in this embodiment includes a bearing 44, a retaining ring 43, an eccentric shaft 42, a positioning structure D, and an adjusting seat 41. The adjusting seat 41 includes a first circular hole 411, a groove 412, and a second circular hole 413. The adjusting seat 41 is provided with a vertically penetrating first circular hole 411, the eccentric shaft 42 is placed in the first circular hole 411, the bearing 44 is installed in the eccentric section 421 of the eccentric shaft 42, the adjusting seat 41 is provided with a transversely penetrating second circular hole 413, and the positioning structure D is disposed in the second circular hole 413.
[0029] In this embodiment, the positioning structure D includes a positioning shaft 45 and a spring 46. An adjusting seat 41 is mounted on the needle bed 1. A vertical through hole 411 is provided on the adjusting seat 41. An eccentric shaft 42 is placed in the vertical through hole 411. A bearing 44 is installed on the eccentric section 421 of the eccentric shaft 42. The bearing 44 is located in the groove 412 in the adjusting seat 41 and abuts against the needle plate 2.
[0030] The eccentric shaft 42 is limited by a retaining ring 43, restricting its up-and-down movement within the through hole 411. The adjusting seat 41 is provided with a transverse through hole 413, and the positioning shaft 45 is placed in the transverse through hole 413. A spring 46 is placed at the rear end of the positioning shaft 45, so that in the normal state, it can press the positioning shaft 45 so that its tapered head is tightly attached to the eccentric shaft 42, and can rebound to a certain extent by external force.
[0031] like Figures 3-4 As shown, the eccentric shaft 42 is provided with several recesses 422, which are used to cooperate with the tapered part of the positioning shaft 45 after rotating a certain angle to achieve positioning after the plate opening gap B is adjusted. The several recesses 422 form the adjustment positions of the plate opening gap B. By rotating the eccentric shaft 42, the eccentric movement of the bearing is controlled, and the movement of the needle plate along the angular direction is controlled.
[0032] Example 2.
[0033] like Figure 5 As shown, except for the positioning structure D, the rest of the structure is the same as that in Embodiment 1, and will not be described again here.
[0034] The positioning structure D in the embodiment comprises a steel ball 47, a spring 48 and a pressing plate 49, and the positioning shaft 45 and the spring leaf 46 in the embodiment 1 are replaced by the steel ball 47, the spring 48 and the pressing plate 49. The steel ball 47 and the spring 48 are placed in the transversely penetrating circular hole 413, and then the pressing plate 49 is used to seal. One end of the spring 48 abuts against the steel ball 47, and the other end abuts against the pressing plate 49. The steel ball 47 is tightly abutted against the eccentric shaft 42 under the action of the spring 48, and after rotating a certain angle, the steel ball 47 cooperates with the recess 422 of the eccentric shaft 42 to form positioning.
[0035] As shown in Figure 6 , it is the application structure of the plate opening gap adjusting device 4, comprising a needle bed 1, a needle plate 2, a transverse limiting block 3 and a plate opening gap adjusting device 4; the needle bed 1 is placed with two needle plates 2, and the two needle plates 2 are placed at a certain angle. The transverse limiting block 3 is installed on both sides of the needle plate 2 to limit the left and right displacement of the needle plate 2.
[0036] As shown in Figure 7 , the head of the two needle plates 2 is provided with a toothed flange 21, and the distance between the two toothed flanges 21 on the two needle plates 2 is called a plate opening gap B. A plurality of plate opening gap adjusting devices 4 are arranged below the needle plate 2, and the size of the plate opening gap between the two needle plates 2 is adjusted by controlling the displacement of the needle plate 2 in the angular direction. When the two needle plates 2 are displaced, the toothed flanges 21 are away from each other, and then the plate opening gap becomes larger. When the toothed flanges 21 are close to each other, the plate opening gap becomes smaller.
[0037] Through the above description, those skilled in the art can implement it.
[0038] In addition, it should be noted that the specific embodiments described in the specification, the shape of the zero, the components, the name taken, etc. can be different, and the above description in the specification is only an example of the structure of the utility model.
