For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 , Figure 2 The diagram illustrates a direct-selection shank structure for a computerized flat knitting machine, comprising a base plate 1. Two sets of triangular components are symmetrically arranged on the left and right sides of the base plate 1, serving as a dual-system control mechanism for the knitting needles. It should be noted that existing computerized flat knitting machines using a single-pressure point structure for the needle selector in the shank structure require the needle to switch between two sets of triangular components to complete the stitching operation when knitting the same row of stitches. This results in very low needle control efficiency and severely impacts knitting efficiency. Therefore, this application makes the following optimizations. Specifically, the triangular components include component A and component B. Component A is entirely disposed on the upper part of the base plate 1 and is used to control the needle's trajectory. It includes a pointed shank 2, an upward needle guide block 3, and a downward needle guide block 4, arranged sequentially from top to bottom on the upper part of the base plate 1. The upward and downward needle guide blocks 3 and 4 are extendable and retractable on the base plate 1, allowing different needle paths to be formed by changing their extension and retraction states as the needle passes through. Symmetrically arranged on both sides of the pointed end 3 are left-hand needle angle triangles 5 and right-hand needle angle triangles 6 to control the depth of needle press during knitting. Furthermore, component B includes a knitting triangle 11 located at the lower part of the base plate 1. Symmetrically arranged on both sides of this knitting triangle 11 are left-hand needle angle triangles 9 and right-hand needle angle triangles 13. Below knitting triangle 11 are symmetrically arranged left-hand needle insertion triangles 10 and right-hand needle insertion triangles 12 to control the trajectory and state of needle selection X during knitting. It should be noted that the left-hand needle insertion triangle 9, left-hand needle insertion triangle 10, knitting triangle 11, right-hand needle insertion triangle 12, and right-hand needle insertion triangle 13 in component B are all movable, extending or retracting into the base plate 1 to adapt to different knitting states.

[0022] The left pre-selection cam 7, the needle lifting cam 8, the middle pre-selection cam 14 and the right pre-selection cam 15 are arranged on the bottom plate 1. The left pre-selection cam 7 is arranged on the left side of the bottom plate 1 and connected with the left component B. The middle pre-selection cam 14 is arranged between the two components B and connected with the component B. The right pre-selection cam 15 is arranged on the right side of the bottom plate 1 and connected with the right component B. The above structure controls the running track of the selection needle X during knitting. In addition, two groups of selection needle holders 16 are symmetrically arranged on the two sides of each component B. The selection needle holder 16 has a selection needle holder blade 161 which can be lifted and fallen. The selection needle holder blade 161 is provided with an upwardly arched pressure point A 162 and a pressure point B 163. When the selection needle X is moved to the needle lifting cam 8, the selection needle X is lifted by the needle lifting cam 8 and is located in the groove between the pressure point A 162 and the pressure point B 163 on the selection needle holder blade 161. If the needle does not need to be withdrawn to perform various knitting actions, the selection needle holder is in a working state. When the selection needle X continues to move, it is pressed down by the pressure point A 162 or the pressure point B 163, so that it cannot be lifted by the above-mentioned needle lifting cam. If the needle needs to be withdrawn, the selection needle holder is in a avoiding state. The selection needle holder blade 161 leaves the selection needle X, so that the selection needle X can normally withdraw the needle to perform various knitting actions.

[0023] It should be noted that on the basis of the above-mentioned embodiment, the groove formed between the pressure point A 162 and the pressure point B 163 on the selection needle holder blade 161 can be passed by the selection needle X without being affected.

[0024] Working principle: see Figure 1 When left row knitting is performed, the selection needle X is lifted by the left needle lifting cam 9 and synchronously lifts the knitting needle Z. At this time, the lower needle turning guide block 4 is in the extended state, the needle cylinder Z1 of the knitting needle Z is connected to the lower needle turning guide block 4, and the needle cylinder Z1 enters the needle path formed by the sharp hill 2 and the lower needle turning guide block 4. At this time, the knitting cam 11 and the upper needle turning guide block 3 are in the retracted state, and the selection needle X cannot be taken away by the knitting cam 11 after moving above the left needle lifting cam 9 and moves along the track formed by the left and right needle lifting cams. The knitting needle Z moves above the lower needle turning guide block 4 and cannot be taken away by the upper needle turning guide block 3 to move along the track formed above the upper needle turning guide block 4. The left row knitting is completed along the knitting track. The right row knitting cam has the same state.

[0025] see Figure 3 When left row knitting is performed, the selection needle X is lifted by the left needle lifting cam 9 and synchronously lifts the knitting needle Z. At this time, the lower needle turning guide block 4 is in the extended state, the needle cylinder Z1 of the knitting needle Z is connected to the lower needle turning guide block 4, and the needle cylinder Z1 enters the needle path formed by the sharp hill 2 and the lower needle turning guide block 4. At this time, the knitting cam 11 and the upper needle turning guide block 3 are in the retracted state, and the selection needle X cannot be taken away by the knitting cam 11 after moving above the left needle lifting cam 9 and moves along the track formed by the left and right needle lifting cams. The knitting needle Z moves above the lower needle turning guide block 4 and cannot be taken away by the upper needle turning guide block 3 to move along the track formed above the upper needle turning guide block 4. The left row knitting is completed along the knitting track. The right row knitting cam has the same state.

[0026] see Figure 4As shown, when the left needle is turned, the selected needle X is lifted by the left needle lifting cam 9, and the knitting needle Z is lifted synchronously. At this time, the lower needle turning guide 4 is in the extended state, and the knitting needle Z needle cam Z1 is contacted by the lower needle turning guide 4. The needle cam Z1 enters the needle path formed by the pointed hill 2 and the lower needle turning guide 4. At this time, the knitting cam 11 is in the retracted state, and the selected needle X moves to the left of the needle lifting cam 9 and cannot be taken away by the knitting cam 11 to form a track. The upper needle turning guide 3 is in the extended state, the knitting needle Z needle cam Z1 enters the needle path formed by the pointed hill 2 and the upper needle turning guide 3, and the left needle turning is completed along the needle path track. The right needle turning cam state is the same.

[0027] See Figure 5 As shown, when the left needle is turned, the left needle lifting cam 9, the left needle turning cam 10 and the knitting cam 11 are in the retracted state, and the selected needle X moves to the convex platform between the left needle lifting cam 9 and the right needle turning cam without being taken away by the left needle lifting cam 9. After being pushed up by the convex platform, it is pushed up by the pointed tip of the right needle turning cam, and the knitting needle Z needle cam Z1 is synchronously taken to the groove below the lower needle turning guide 4. After the knitting needle Z needle cam Z1 is taken down from the groove, the left needle turning is completed along the needle turning track. When the right needle turning cam is turned, the right needle lifting cam 13, the right needle turning cam 12 and the knitting cam 11 are in the retracted state, and the track is the same as the left needle turning.

[0028] See Figure 2 As shown, the present example adopts a double pressure point needle selector, and the needle selector blade is provided with two pressure points A161 and B162, which respectively control the needle pressing action when turning left or right. When selecting the needle, the selected needle X moves to the lifting cam 8, and is lifted by the lifting cam 8. The selected needle X is in the groove between the pressure point A161 and the pressure point B162 on the needle selector blade. If the needle does not need to be taken out for various needle knitting actions, the needle selector is in the working state, and the selected needle X is pressed down by the pressure point A161 or the pressure point B162 when it continues to move, so that it cannot be lifted by the needle lifting cam. If the needle needs to be taken out, the needle selector is in the avoiding state, and the needle selector blade 161 avoids the selected needle X, so that the needle can normally be taken out for various needle knitting actions.

[0029] In the flat knitting machine, the machine head moves to the right of the needle plate or to the left of the needle plate as a row. The present example also has the same row knitting lifting function.

[0030] See Figure 6 As shown, when the machine head needs to knit the lifting point on the right, the machine head is pre-selected before the machine head moves to the right. The selected needle is selected by the needle selector 16 when the machine head moves to the left. When the lifting point is taken out, the needle selector blade is in the avoiding state, the selected needle X is pushed to the high point by the pointed tip 151 of the right pre-selection cam 15, and the knitting needle Z is synchronously pushed to the lifting point. The height of the pointed tip 151 is the same as the height of the left and right needle lifting cams. When the knitting needle is taken out, the needle selector blade is in the working state, and the selected needle X is pressed down by the pressure point A161, so that it cannot be pushed up by the pointed tip 151 of the right pre-selection cam 15.

[0031] See Figure 7 As shown, when the machine head is knitting a loop on the right system, the needle that will be looped is pushed to the loop point in advance, and the machine head moves along the loop trajectory. In order to avoid affecting the loop trajectory, the right system loop triangle 6 needs to be at the uppermost point, so that the lower surface does not exceed the loop trajectory line. When the knitting needle reaches the position of the selector, the selector blade is in the avoiding state, and the selector X is taken away by the right needle raising triangle 13 and the knitting triangle 11. At this time, the upper and lower needle turning guide blocks are in the retracted state, and the loop needle and the knitting needle realize the same row of knitting loops along the loop trajectory and the knitting trajectory. When the left system needs to knit a loop while moving to the right, the selector is used to reselect after the right system knits a loop. The reselection method is the same as the above-mentioned right system selection method. Then the needle that needs to be looped is pushed to the loop point by the intermediate pre-selection triangle, and the subsequent action is the same as the above-mentioned right system loop knitting.

[0032] See Figure 8 As shown, when the machine head is knitting a loop on the right system, the needle that will be looped is pushed to the loop point in advance, and the machine head moves along the loop trajectory. In order to avoid affecting the loop trajectory, the right system loop triangle 6 needs to be at the uppermost point, so that the lower surface does not exceed the loop trajectory line. When the knitting needle reaches the position of the selector, the selector blade is in the avoiding state, and the selector X is taken away by the right needle raising triangle 13 and the knitting triangle 11. At this time, the upper and lower needle turning guide blocks are in the retracted state, and the loop needle and the knitting needle realize the same row of knitting loops along the loop trajectory and the knitting trajectory. When the left system needs to knit a loop while moving to the right, the selector is used to reselect after the right system knits a loop. The reselection method is the same as the above-mentioned right system selection method. Then the needle that needs to be looped is pushed to the loop point by the intermediate pre-selection triangle, and the subsequent action is the same as the above-mentioned right system loop knitting.

[0033] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
