[0027] It should be noted that similar reference numerals and letters refer to similar items throughout the accompanying drawings, so once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0028] As Figure 1 shown, the embodiment proposes a weft knitting machine yarn guide device, including lower clamp 1 and upper clamp 2, through lower clamp 1 and upper clamp 2, it can be fixed in the frame body containing yarn, the top of lower clamp 1 is provided with locking mechanism 3, the top of lower clamp 1 is provided with yarn guide mechanism 4;

[0029] As Figure 2 and Figure 3 shown, locking mechanism 3 includes two bolts 31 threaded in the top of lower clamp 1, its design can provide locking ability, so that lower clamp 1 and upper clamp 2 can be separated by bolt 31, two bolts 31 are externally threaded in the inside of upper clamp 2, the bottom of two bolts 31 is fixedly connected with bottom sheet 33, its design can provide clamping ability, the outside of bolt 31, i.e. the side close to bottom sheet 33 is rotatably connected with clamping block 34, its design can provide clamping ability, by limiting bottom sheet 33, clamping block 34 can not fall off, so that clamping block 34 can rotate freely outside bolt 31, by the rotation of clamping block 34, lower clamp 1 and upper clamp 2 cannot be separated, the inside of lower clamp 1 is installed with connecting assembly 32, the bottom of upper clamp 2 is provided with alignment slot 35, its design can provide alignment ability, when bolt 31 is spirally rotated to the top of lower clamp 1, clamping block 34 can be moved upward, when moving, by rotating clamping block 34, clamping block 34 can be clamped in the inside of alignment slot 35.

[0030] As Figure 2 shown, connecting assembly 32 includes two connecting columns 321 fixedly connected in the inside of lower clamp 1, its design can provide good connecting ability, so that lower clamp 1 and upper clamp 2 can move vertically, the outside of bolt 31 is located in the inside of connecting column 321, the outside of connecting column 321 is provided with flow-through groove 322 on both sides, its design can provide flow-through ability, when adjusting the clamping of frame, connecting column 321 will pass through the bottom of upper clamp 2, by the space provided by flow-through groove 322, clamping block 34 can pass through well, preventing from causing jamming, and the outside of clamping block 34 is slidably connected in the inside of flow-through groove 322.

[0031] As Figure 3As shown, the outer sliding connection of the clamping block 34 is in the inner part of the positioning groove 35, and the outer part of the clamping block 34 is attached to the inner wall of the positioning groove 35. The design can effectively stably connect the lower clamp 1 and the upper clamp 2, prevent falling, and after use, rotate the bolt 31 again to make the clamping block 34 separate from the inner part of the positioning groove 35, then rotate to the same level as the connecting column 321, so that the upper clamp 2 and the lower clamp 1 can be separated, and good collection ability can be provided.

[0032] As shown in Figure 1 , Figure 4 and Figure 5 , the yarn guide mechanism 4 includes a support frame 41 fixedly connected to the top of the lower clamp 1, which can provide good support ability and stability during yarn conveying. The outer two sides of the support frame 41 are provided with guide holes 42, which can provide good guiding ability, so that the yarn can pass through the inside of the guide holes 42, preventing the formation of a ball during use that affects the quality.

[0033] As shown in Figure 4 , the top of the support frame 41 is rotatably connected with a support column 43, which can provide support ability and stable support. The outer part of the support column 43 is rotatably connected with two pressure plates 45, which can provide good limiting ability to prevent the yarn from floating due to its light weight during guiding.

[0034] As shown in Figure 4 , the top of one of the pressure plates 45 is fixedly connected with a connecting rod 44, which can provide good connection ability. The connecting rod 44 is provided upward to separate the two pressure plates 45, providing convenience for the staff. The top of the support frame 41, i.e. the side close to the pressure plate 45, is rotatably connected with a rotating column 46, which can provide rotation ability.

[0035] As shown in Figure 5 , the outer part of the rotating column 46, i.e. the side close to the pressure plate 45, is fixedly connected with a plurality of hooks 47, which can provide hooking ability. When used for a long time, the yarn will form a ball due to friction. By rotating the rotating column 46 to drive the hooks 47 to rotate, the ball can be hooked, preventing the formation of a sheet during processing. The length of the hook 47 is less than the radius of the pressure plate 45. By gathering the yarn together, a large amount of yarn ball can be collected when hooked, without stopping the yarn processing for collection.

[0036] Specifically, the yarn guide device of the weft knitting machine is fixed on the frame body containing the yarn in use. When the lower clamp 1 and the upper clamp 2 need to be close to each other, the bolt 31 is rotated and screwed down in the threaded hole at the top of the lower clamp 1. As the bolt 31 is screwed in, the bottom piece 33 at the bottom of the bolt 31 drives the clamping block 34 to move upwards. During the movement, the clamping block 34 slides along the flow-through groove 322 outside the connecting column 321 (as shown in Figure 2 When the clamping block 34 moves to the appropriate position, it is rotated so as to be clamped inside the alignment groove 35 at the bottom of the upper clamp 2. At this time, the outer part of the clamping block 34 tightly fits the inner wall of the alignment groove 35, thereby stably connecting the lower clamp 1 and the upper clamp 2 together and preventing them from falling off. When the lower clamp 1 and the upper clamp 2 need to be separated, the bolt 31 is rotated again so as to be unscrewed upwards in the threaded hole at the top of the lower clamp 1. As the bolt 31 is unscrewed, the clamping block 34 moves downwards. During the movement, the clamping block 34 slides along the flow-through groove 322 and comes out of the inside of the alignment groove 35. Subsequently, the clamping block 34 is rotated to the position where it is flush with the connecting column 321, at which time the upper clamp 2 and the lower clamp 1 can be smoothly separated, thereby completing the collection work and facilitating storage and installation (as shown in Figure 3

[0037] When working, the yarn first passes through the guide holes 42 outside the support frame 41 on both sides. The design of the guide holes 42 can ensure smooth passage of the yarn and avoid the formation of a ball during the conveying process, thereby ensuring the quality of the yarn. After the yarn passes through the guide holes 42, it enters between the two pressure plates 45. The pressure plates 45 prevent the yarn from floating due to its light weight during the guiding process by virtue of their limiting ability, thereby ensuring the stability of the yarn during the conveying process (as shown in Figure 4 If it is necessary to adjust the pressure plates 45, the two pressure plates 45 can be separated by pulling the connecting rod 44 upwards, thereby providing convenience for the workers. During the conveying process of the yarn, the yarn will form a ball due to friction over time. At this time, the hook 47 outside the rotating column 46 can be rotated by rotating the rotating column 46. The design of the hook 47 can hook the ball to prevent it from affecting the sheet during the processing process. Since the length of the hook 47 is less than the radius of the pressure plate 45, when the yarn is gathered together, the hook 47 can drive a large number of yarn balls to be collected when it is hooked, so that it is not necessary to stop the processing of the yarn to perform the collection work, thereby improving the production efficiency (as shown in Figure 5 ).

[0038] All the technical features in the embodiment can be freely combined according to actual needs.

[0039] ​The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
