Flat knitting machines have effectively reduced energy consumption and emissions, improved the performance of flat knitting machines, and contributed to the sustainable development of the textile industry by optimizing structural design, adopting high-efficiency motors and energy-saving control systems. At present, part of the triangles and weaving tracks of the commonly used flat knitting machine bottom plate are sunk into the bottom plate. The larger the triangles sunk into the bottom plate, the more complex the triangle structure is, which increases the production and processing costs. Utility Model Content

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1

[0020] A triangle mechanism capable of realizing function switching, as shown in the figure, comprises a knitting needle track 1 provided on a horizontal knitting machine and a transfer needle track 2 located above the knitting needle track 1, and also comprises a switching triangle 3 movably installed on the horizontal knitting machine and movable outwardly to the knitting needle track 1, a raised switching protrusion 31 is installed on the switching triangle 3, the switching protrusion 31 cooperates with the needle track opening of the knitting needle track 1, the upper outer wall surface of the switching protrusion 31 cooperates smoothly with the lower inner wall surface of the transfer needle track 2 to form a continuous wall surface, when the switching triangle 3 is transferred from the bottom plate of the horizontal knitting machine to the protrusion on the knitting needle track 1, the switching protrusion 31 blocks the knitting needle track 1 to prevent the needle from sliding into the knitting needle track 1, and at the same time guides the needle to slide into the transfer needle track 2 along the upper outer wall surface of the switching protrusion 31 and the lower inner wall surface of the transfer needle track 2.

[0021] The herringbone cam 4, the switching cam 3 and the knitting cam 5 are installed on the bottom plate from top to bottom in sequence. The switching cam 3 is movably embedded on the bottom plate on the knitting needle track 1 between the herringbone cam 4 and the knitting cam 5. The herringbone cam 4 is provided with a transfer needle track 2, and the knitting cam 5 is provided with a receiving needle track. The function of the switching cam 3 is mainly reflected in the switching of functions: when the switching cam 3 protrudes from the bottom plate, the needle enters the transfer needle track 2; when the switching cam 3 sinks into the bottom plate, the switching cam 3 enters the knitting needle track 1. The docking design of the two sides of the switching cam 3 and the transfer track 2 enables the position of the track where the needle is located to be adjusted quickly and accurately when switching the knitting mode, thereby achieving a smooth transition of different functions.

[0022] There are two switching protrusions 31 located at the left and right ends of the switching cam 3 , and the two switching protrusions 31 are respectively matched with the left and right needle path openings of the knitting needle path 1 .

[0023] Example 2

[0024] The same as Example 1, the difference is that the upper part of the switching triangle 3 is also provided with an upward needle path protrusion 32, and the needle path protrusion 32 cooperates with the knitting needle path 1, so that when the switching triangle 3 is transferred from the bottom plate of the horizontal knitting machine to the protrusion on the knitting needle path 1, the switching protrusion 31 and the needle path protrusion 32 can be filled in the knitting needle path 1 to prevent the stitches from being accidentally inserted.

[0025] There are two switching protrusions 31 which are fixedly connected to the left and right sides of the needle track protrusion 32 .

[0026] The raised part on the switching triangle 3 is not only set on both sides of the knitting needle track 2, but can also be embedded in the knitting needle track 1. When the switching triangle 3 protrudes from the bottom plate, because its shape fits the shape of the knitting needle track 1, it can tightly fill the entire knitting needle track 1 space. In this way, during the high-speed operation of the bottom plate, the needle cannot enter the knitting needle 1 by mistake, thereby greatly reducing operational errors and product quality problems. When the switching triangle 3 is retracted into the bottom plate, it can make room for the knitting needle track 1 so that the needle can push the knitting needle through the knitting needle track 1 to complete the knitting function. This flexible switching mechanism makes the entire knitting process smoother and more efficient. This structure of switching needle tracks can improve the production efficiency and product quality of the equipment.

[0027] Example 3

[0028] The same as the first embodiment, except that an exit slope 33 is provided on the outer side of the switching protrusion 31. The end of the switching protrusion 31 that cooperates with the needle and blocks it from entering the knitting needle track 1 is defined as the working end, and the other end of the switching protrusion 31 is defined as the exit end. The exit slope 33 is provided on the outer side of the exit end of the switching protrusion 31, and the exit slope 33 is inclined inwardly toward the bottom plate. The switching protrusion 31 can also be provided in a split body, and the switching triangle can be installed on a guide column, a slider, a connecting rod, a cam or other components that transmit motion. The main body of the switching protrusion 31 is provided with an exit slope 33, and the exit slope 33 is provided at the intersection of the outer side of the knitting needle track 1 and the switching triangle 3. When a needle cannot enter the knitting needle track 1 by mistake, the exit slope 33 also allows the needle to exit the knitting needle track 1 smoothly, thereby reducing the probability of needle collision, improving the stability of the triangle, and further improving the overall work efficiency.

[0029] Example 4

[0030] The same as the first embodiment, except that the switching cam 3 is provided with a mounting hole or a mounting groove.

[0031] The flat knitting machine is also provided with a switching drive assembly, which is connected to the switching cam 3 and drives the switching cam 3 to move on the bottom plate.

[0032] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
