[0026] like Figure 1-Figure 4 As shown, the present embodiment provides a yarn fixing hook 1 for weaving control of a large circular machine 100, comprising a yarn fixing hook 1, which is adjustably mounted on the large circular machine 100 through an adjusting device 2, and one end of the yarn fixing hook 1 is provided with a yarn controlling portion 3 for changing the yarn height, the yarn controlling portion 3 comprises an inclined surface 31 for assisting the yarn to enter and a notch 32 for limiting the yarn, the adjusting device 2 comprises a basic bracket 21, a transverse adjustment bracket 22, and a longitudinal adjustment bracket 23, a connecting hole 11 is provided on the yarn fixing hook 1, the basic bracket 21 is installed and locked through the connecting hole 11 by a connecting piece, the basic bracket 21 is slidably matched with the top end of the transverse adjustment bracket 22 for adjustment, and the side end of the transverse adjustment bracket 22 is slidably matched with the longitudinal adjustment bracket 23 for adjustment.
[0027] Furthermore, a needle disc is provided on the circular knitting machine 100, and the yarn fixing hook 1 is adjustably mounted on the upper fixing seat of the needle disc through the adjusting device 2.
[0028] Furthermore, the circular knitting machine 100 is provided with a syringe mouth, and the yarn fixing hook 1 is adjustably mounted on the syringe mouth fixing seat through the adjusting device 2.
[0029] Furthermore, a connection port 221 is provided at the top of the transverse adjustment bracket 22 , a first transverse adjustment port 222 is horizontally provided on the transverse adjustment bracket 22 , and the base bracket 21 is locked and connected to the transverse adjustment bracket 22 by a first screw 223 and a first gasket 224 .
[0030] Furthermore, a screw hole 225 is set on one side where the transverse adjustment bracket 22 is connected to the longitudinal adjustment bracket 23, and a second transverse adjustment hole 231 is set on the longitudinal adjustment bracket 23. One side end of the transverse adjustment bracket 22 is matched and connected with the second transverse adjustment hole 231, and the longitudinal adjustment bracket 23 is locked and connected with the transverse adjustment bracket 22 by a second screw 232 and a second gasket 233.
[0031] Furthermore, a longitudinal adjustment opening 234 is provided on the longitudinal adjustment bracket 23. The longitudinal adjustment opening 234 is essentially a slot provided through the bottom end of the longitudinal adjustment bracket 23. Specifically, the longitudinal adjustment bracket 23 can be locked and connected by gaskets and screws. The longitudinal adjustment opening 234 can be used to move the longitudinal adjustment bracket 23 up and down as a whole to adjust its relative position.
[0032] Furthermore, the connecting piece is a connecting screw or a rivet.
[0033] Furthermore, the yarn controlling portion 3 is in the shape of a sheet, with a downward hook shape on the outside and an inverted V shape on the inside, and a plurality of inclined surfaces for controlling the yarn are arranged on the edge.
[0034] Furthermore, the basic support 21 and the yarn fixing hook 1 on the basic support 21 move forward and backward along the lateral adjustment support 22 .
[0035] Furthermore, the lateral adjustment bracket 22 moves left and right along the longitudinal adjustment bracket 23 .
[0036] Reference Figure 3 The aforementioned forward and backward movement refers to the X-axis direction; the aforementioned left and right movement refers to the Z-axis direction; the aforementioned up and down movement refers to the Y-axis direction.
[0037] The above-mentioned large circular machine 100 knitting control fixed yarn hook 1 structure can be specifically installed at the position of the large circular machine 100 where the needle is pressed into a loop. Based on this structure, when the yarn is not looped, the yarn is woven as a floating thread. When the machine is running, the floating thread will be forced into the inverted V-shaped groove of the fixed yarn hook, and the yarn will be pressed by the yarn control part 3 on the fixed yarn hook 1. No matter how long the floating thread is, the yarn can be stably controlled at the corresponding height position, thereby ensuring that the yarn can be efficiently eaten; usually, the fixed yarn hook 1 is provided with one end of the yarn control part 3 0.2mm-0.8mm away from the needle disk, wherein the thicker the yarn, the larger the gap; and the reason why floating thread appears is that the yarn mouth originally has a certain height, and a yarn hole is set on the yarn mouth. The longer the yarn, the higher the yarn close to the yarn mouth is likely to be, forming a floating thread. If it is too high, it cannot be eaten, and the longer the yarn, the more likely it is to run onto the needle disk, thereby affecting normal knitting.
[0038] The large circular knitting machine 100 in the utility model uses a yarn fixing hook 1 to control weaving, which can stably control the yarn and lower the corresponding height position. The adjusting device 2 can efficiently cooperate to control the weaving position and angle of the yarn during floating line weaving. The utility model has a simple structure, low use cost and good use effect.
[0039] Furthermore, the connecting parts are not limited to screws and rivets, and any parts that can achieve the connection function effect, such as screws, etc.
[0040] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
