DETAILED DESCRIPTION

[0023] The present application will be further described in detail below with reference to the drawings.

[0024] Embodiment:

[0025] With reference to Figures 1-4 The computerized flat knitting machine thread pressing mechanism disclosed by the present application comprises a support seat 1, opposite two side edges of the top of the support seat 1 are connected with support plates 2, vertical slots 3 are formed in the top of the support plates 2, vertical rods 4 are arranged in the two vertical slots 3 through pressing supports 11 respectively;

[0026] A pressure rod 5 is provided between the two vertical rods 4. The two ends of the pressure rod 5 are slidably connected to the two vertical rods 4 respectively. A number of guide grooves 6 are provided on the outer periphery of the pressure rod 5. A guide disc 7 is provided in the guide groove 6. A guide ring 8 is rotatably connected to the outer periphery of the guide disc 7. A sliding groove 9 is provided on the side wall of the guide disc 7. The guide disc 7 is slidably connected to the guide groove 6 through the sliding groove 9. A positioning spring 10 is connected to both the upper and lower ends of the sliding groove 9. The end of the positioning spring 10 is connected to the inner periphery of the guide groove 6. A guide member 12 is also provided between the two support plates 2.

[0027] In this embodiment, reference Figure 1 When the yarn needs to be pressed during the conveying process, it needs to be guided by the guide member 12. After passing through the guide member 12, the yarn is located at the bottom of the guide ring 8. Then, when pressing the yarn, the pressing support member 11 drives the vertical rod 4 and the pressing rod 5 to descend. At this time, several guide rings 8 press down on the corresponding yarns. (Refer to...) Figure 4 After the guide ring 8 presses down on the yarn, the tension on the yarn will increase. At this time, the guide ring 8 will be pushed upward by the yarn, which will drive the guide disc 7 to rise, so that the guide disc 7 passes through the slide groove 9 in the guide groove 6 (reference). Figure 4 Slide upwards inside;

[0028] Due to factors such as friction during conveying, tension during knitting, and pressure during pressing, the tension of several yarns will vary. At the same time, the number of guide rings 8 and guide discs 7 is the same as the number of yarns. Therefore, each yarn can push the guide rings 8 and guide discs 7 independently, avoiding the synchronous pressing force on all yarns, which could cause the tension of some yarns to exceed their own threshold due to other factors, resulting in breakage.

[0029] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the lower pressure support 11 includes a lower pressure plate 13. The two ends of the lower pressure plate 13 are slidably connected to the two vertical grooves 3 respectively. The top sides of the two ends of the lower pressure plate 13 are fixedly connected to the bottom ends of the two vertical rods 4 respectively. The top sides of the two ends of the lower pressure plate 13 are each connected to a support spring 14. The top of the support spring 14 is connected to the outer periphery of the pressure rod 5. A hydraulic telescopic rod 15 is fixedly installed in the middle of the top side of the support base 1. The telescopic end of the hydraulic telescopic rod 15 faces upward and is connected to the middle of the bottom side of the lower pressure plate 13.

[0030] In this embodiment, reference Figure 1Two ends of the lower pressing plate 13 are respectively slidably connected in the two vertical grooves 3, and the top sides of the two ends of the lower pressing plate 13 are respectively fixedly connected with the bottom ends of the two vertical rods 4, so that the lower pressing plate 13, the supporting spring 14 and the vertical rod 4 are lowered when the hydraulic telescopic rod 15 is retracted, and the pressing rod 5 fixedly connected with the top end of the supporting spring 14 is lowered, so that the pressing rod 5 can drive the guide ring 8 to be lowered to press the yarn, and the supporting spring 14 can relieve the pressure on the yarn when the pressure on the yarn is large, so that the yarn is not broken due to too large pressing force.

[0031] In further preferable embodiments of the present application, as shown in Figure 1 The guide 12 comprises two groups of positioning blocks 16, each group of positioning blocks 16 comprises two positioning blocks 16, the two positioning blocks 16 in the same group are fixedly connected with the top sides of the opposite two edges of the support plate 2, and the two positioning blocks 16 correspondingly are rotatably connected with a guide roller 17, and the guide roller 17 is provided with guide grooves 18 in a number equal to that of the guide rings 8.

[0032] In the embodiment, as shown in Figure 1 The top sides of the opposite two edges of the support plate 2 are fixedly connected with the positioning blocks 16, the two positioning blocks 16 correspondingly are rotatably connected with the guide roller 17, and the guide roller 17 is provided with the guide grooves 18 for guiding the yarn, the yarn passes over the guide roller 17 and is put into the corresponding guide groove 18, and then passes over the corresponding guide ring 8 downward, and then passes over the other guide roller, so as to guide the yarn and press the yarn when the pressing rod 5 is lowered, so as to physically limit the yarn and avoid the yarn from being loose and deviating.

[0033] In further preferable embodiments of the present application, as shown in Figure 2 The guide ring 8 is provided with an annular groove 19 on the outer periphery, and the inner side wall of the annular groove 19 is arranged in an inwardly concave arc shape.

[0034] In the embodiment, as shown in Figure 2 The guide ring 8 is provided with the annular groove 19 arranged in an inwardly concave arc shape, so that the corresponding yarn can be located in the annular groove 19 when passing over the bottom of the guide ring 8, and the yarn can be kept in the annular groove 19 when being pressed, so as to avoid the yarn from being loose and deviating.

[0035] The implementation principle of the above embodiment is that the lower pressing plate 13 is lowered when the hydraulic telescopic rod 15 is retracted, and the supporting spring 14 and the vertical rod 4 are lowered, and the pressing rod 5 fixedly connected with the top end of the supporting spring 14 is lowered;

[0036] At this time, several guide rings 8 press the corresponding yarns, after the guide rings 8 press the yarns, the tension of the yarns will increase, at this time the guide rings 8 will be subjected to the upward thrust of the yarns, and then drive the guide disc 7 to rise, so that the guide disc 7 slides upward in the guide groove 6 through the sliding groove 9, and the number of the guide rings 8 and the guide disc 7 is the same as the number of the yarns, so each yarn can independently push the guide ring 8 and the guide disc 7, avoiding that all the yarns are subjected to the synchronous pressing force, causing the tension of part of the yarns to exceed the threshold value borne by itself due to other factors, and thus the phenomenon of rupture occurs;
