Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically to a motorless needle pusher triangular needle selection plate structure. Background Technology

[0002] The triangular pusher plate is a key component in computerized flat knitting machines used to push the needles to knit. Through its triangular design, it utilizes a pusher mechanism to achieve precise movement of the needles and knitting actions, thereby completing various complex knitting patterns and textures.

[0003] In existing computerized flat knitting machines, the triangular needle pusher plate moves the needles up and down within the needle groove through the pushing action of the triangular components, completing the knitting action. At the same time, the needle pusher mechanism precisely controls the movement distance and time of the needles to achieve various knitting patterns. However, due to the need for regular maintenance and upkeep to ensure long-term stable operation, the triangular needle pusher plate is generally controlled by a motor for extension and retraction. The motor may be damaged after prolonged use, affecting the normal operation of the needle selection. Moreover, the motor is expensive, and regular replacement and maintenance increase the operating cost of the equipment. Therefore, we propose a motorless triangular needle pusher plate structure to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a motorless pusher triangular needle selection plate structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motorless push-needle triangular needle selection plate structure, comprising a base plate and a needle selector mounted on the bottom end of the base plate. The lower end of the base plate is provided with a pair of side-lifting needle triangles and a pair of center-lifting needle triangles. The side-lifting needle triangles and center-lifting needle triangles are symmetrically arranged on both sides of the lower edge of the base plate. The side-lifting needle triangles are inverted triangular in shape. Multiple rectangular grooves are formed on the surface of the base plate. The positions of the needle selector correspond to the side-lifting needle triangles and center-lifting needle triangles on both sides, respectively.

[0006] The side lifting needle triangle is equipped with a left push needle triangle and a right push needle triangle respectively. The middle lifting needle triangle is equipped with a pair of middle push needle triangles respectively. The top of the base plate is provided with slide rails A, H and B respectively. The top of the needle selector is provided with multiple sets of knitting components.

[0007] Preferably, the needle selector comprises a needle selector base, a needle selector blade, a rotating shaft, and internal electronic components. The needle selector base is installed in a rectangular groove on the surface of the base plate. The top of the needle selector base has a storage slot, and the sides of the storage slot have round holes. The rotating shaft is rotatably disposed inside the round holes. The needle selector blade is installed on the top of the rotating shaft, and the internal electronic components are electrically connected to the rotating shaft. The rotating shaft can rotate under the control of the electronic components.

[0008] The tip of the needle selector blade is higher than the surface of the base plate, and the needle selector blade can move under the action of the rotating shaft, which can be used to realize the working state and the avoidance state.

[0009] Preferably, the needle selector blade has a pair of pressure points on its top. The pressure points are trapezoidal protrusions and are symmetrically arranged on the top of the needle selector blade. The pressure points on both sides are respectively coordinated with the pressure action when the machine head moves to the left and right. There is a gap between the pressure points.

[0010] Preferably, the knitting assembly includes a needle selector X, which is located directly above the needle selector. A needle groove is formed on the surface of the base plate, and the needle selector X is engaged inside the needle groove. The bottom of the needle selector X is provided with multiple needle selector feet. The needle selector X is composed of needle selector feet at several positions. The positions of the needle selector feet at the bottom of the needle selector X correspond to the needle selector blade. The bottom of the needle selector X is provided with a push needle foot and a return needle foot. The needle selector X is pushed by the push needle foot driven by the push needle triangle and returned to its original position by the return needle foot. The needle selector blade is normally in an avoidance state, pressed into the needle selector foot teeth, to control the needle selector X to be engaged in the needle groove and not rise along the needle selector triangle. When the needle selector blade is in the working state and swings upward, the needle selector feet at the bottom of the needle selector X abut against the needle selector blade, which allows the needle selector X to rise along the needle selector triangle, thereby realizing the push needle.

[0011] Preferably, the knitting assembly further includes a pushing long needle C and a spring needle T. The spring needle T is disposed on the upper end of the needle selector X. The spring needle T can be pushed into the slide rails A, H and B under the action of the needle selector X. The pushing long needle C is disposed on the upper end of the spring needle T. The pushing long needle C is used to control the pushing long needle C to enter different knitting positions in the three positions of slide rail A, slide rail H and slide rail B. Slide rail A is the knitting and turning position, slide rail H is the hanging and joining position, and slide rail B is the non-knitting position.

[0012] Preferably, the top of the left push needle triangle is provided with push needle point one, push needle point two and push needle point three respectively. Push needle point one, push needle point two and push needle point three can contact the needle selection X to adjust different knitting states, realize knitting or turning stitch, hanging stitch or joining stitch, and not knitting.

[0013] Preferably, the base plate is also provided with a needle selection triangle, and the top of the needle selection triangle is respectively provided with a push needle point four and a push needle point five. The needle selection triangle is used to control the needle selection X to directly push the long needle C into different knitting positions, namely the turn-over position, the hanging eyelet position or the joining position, and the no-knit position.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Compared to the traditional needle selection cap structure where the needle pusher triangle is motor-controlled to extend and retract, this invention eliminates the motor-controlled needle pusher triangle structure, making the needle pusher triangle fixed. Furthermore, by changing the needle selector structure, it achieves the same function as the traditional motor-controlled needle pusher triangle structure.

[0016] 2. By making the pusher triangle fixed, this invention can effectively reduce production costs and subsequent maintenance costs compared to setting up a motor for control. Moreover, the mechanical fixed transmission is more stable than the motor transmission, which can also reduce problems generated during the production process and lower the defect rate.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, please refer to Figures 1-10 The present invention provides a technical solution:

[0037] See Figure 10As shown, for the mountain board in Example 1, the function of the needle selector X902 is to push the spring needle T903 to three positions: slide rail A101, slide rail H102, and slide rail B103. These three positions control the operation of the long needle C901. Slide rail A101 is used for knitting and turning stitches, slide rail H102 is used for hanging stitches and joining stitches, and slide rail B103 is the non-knitting position. The needle selector X902 consists of several needle selector feet X4 in different positions, which correspond to the number of needle selector blades 22. The needle selectors X902 are evenly distributed in groups. The needle selector X902 can be pushed by any one of the left push needle triangle 5, the middle push needle triangle 6, and the right push needle triangle 7, pushing the push needle foot X2 at the bottom of the needle selector X902. The needle return is achieved by the return needle foot X3.

[0038] See Figure 4-7 As shown, the needle selector 2 is roughly composed of a needle selector base 21, a needle selector blade 22, a rotating shaft 23, and internal electronic components. The needle selector blade 22, the rotating shaft 23, and the electronic components are all installed inside the needle selector base 21. The needle selector base 21 is installed on the base plate 1, so that the needle selector blade 22 protrudes from the base plate surface. The needle selector blade 22 is set on the top of the rotating shaft 23, so that the needle selector blade 22 can realize the working state and the avoidance state through the rotating shaft 23 and the electronic components. The needle selector blade 22 is provided with two needle pressing points 221, which are respectively coordinated with the needle pressing action when the machine head moves to the left and right. The needle selector 2 system is provided with two symmetrical left and right needle pressing points, which respectively control the needle pressing action when the machine head moves to the left and right.

[0039] See Figure 1 As shown, the non-motorized pusher triangle type needle selector plate structure has the following main components: base plate 1, needle selector 2, side lifting needle triangle 3, middle lifting needle triangle 4, left pusher triangle 5, middle pusher triangle 6, and right pusher triangle 7.

[0040] See Figure 1 As shown, when the machine head moves to the left, if system 1 needs to knit or turn needles, the spring needle T903 needs to be pushed to the slide rail A101 position. When the machine head moves above the needle selector X902, the needle selector X902 is lifted by the side lifting triangle 3. The side lifting triangle 3 is in the shape of an inverted triangle and is positioned directly below the needle selector 2. Figure 8 As shown, the needle selector X902 is raised to the working position. At this time, the needle selector blade 22 is in the avoidance state. After passing the left push needle triangle 5 and the push needle point 3 53, the needle selector X902 is pushed by the push needle point 1 51 to push the spring needle T903 to the slide rail A101 position, which is used to realize knitting or needle turning.

[0041] See Figure 2As shown, when the machine head moves to the left, if system 1 needs to lift the needle or attach a needle, the spring needle T903 needs to be pushed to the slide rail H102 position. Before the machine head moves to the left, when the machine head moves to the right, when the machine head moves above the needle selector X902, the needle selector X902 is lifted by the side lifting triangle 3. The side lifting triangle 3 is in an inverted triangle shape, so that the needle selector X902 is lifted to the working position. At this time, the needle selector blade 22 is in the avoidance state. After the machine head continues to move to the right, the needle selector X902 is pushed by the left pushing triangle 5 at the second pushing point 52, pushing the spring needle T903 to the slide rail H102 position. Wait until the machine head runs out of the range of the needle selector X902. The machine head begins to move to the left. During this movement, the needle selector blade 22 is in operation. When the machine head moves above the needle selector X902, the needle selector X902 is lifted by the side lifting triangle 3. When lifted, the needle selector foot X4 at the bottom of the needle selector X902 can be avoided due to the gap between the two pressing points 221 of the needle selector blade 22. Since the needle selector blade 22 is in operation, when the machine head continues to move to the left, the needle selector is pressed down by the pressing point 221 on the right side of the needle selector blade 22 and cannot be pushed by the push needle 51. The spring needle T903 continues to move along the slide rail H102, thereby achieving the lifting or attaching of the needle.

[0042] See Figure 3 As shown, when the knitting head moves to the left, if system 1 needs to achieve non-knitting, the spring needle T903 needs to be pushed to the slide rail B103 position. Before the knitting head moves to the left, when the knitting head moves to the right, and the knitting head moves above the needle selector X902, the needle selector X902 is lifted by the side lifting triangle 3. The side lifting triangle 3 is in an inverted triangle shape, so that the needle selector X902 is lifted to the working position. At this time, the needle selector blade 22 is in the working state, and the needle selector X902 is pressed down by the needle press point 221 on the left side of the needle selector blade 22, so that it cannot be knitted with the needle above. Similar to the needle lifting or needle receiving action described above, the spring needle T903 is pushed to the slide rail H102 position by the left needle pusher triangle 5 and the needle pusher point 2 52. After the spring needle T903 is reset and is in the slide rail B103 position, the machine head moves to the left. At this time, the needle selector blade 22 is in working state. The needle selector X902 is pressed down by the needle presser point 221 on the right side of the needle selector blade 22, so that it cannot be pushed away by the needle pusher triangle 5 and the needle pusher point 1 51. This makes the spring needle T903 move along the slide rail B103 position, thereby achieving non-knitting.

[0043] Example 2, please refer to Figures 11-16 The present invention provides a technical solution:

[0044] See Figure 11-16 As shown, for the mountain board in Example 2, the function of needle X902 is to directly push the long needle C901 into three positions: knitting or turning stitch, hanging stitch or joining stitch, and no knitting.

[0045] See Figure 11As shown, when the machine head moves to the left, if system 1 needs to perform knitting or turning stitches, the pusher needle C901 needs to be pushed to the knitting turning stitch position. Before the machine head moves to the left, when the machine head moves to the right, the machine head moves above the selector needle X902, and the side lifting needle triangle 3 lifts the selector needle X902, so that the selector needle X902 is lifted to the working position. At this time, the selector needle blade 22 is in the avoidance state. After the machine head continues to move to the right, the selector needle X902 is pushed by the push needle triangle 8 and the push needle point 4 81 and moves along the needle path. When the machine head runs out of the range of the selector needle X902, the machine head starts to move to the left. When moving to the left, the selector needle X902 moves along the needle path, and pushes the pusher needle C901 to the knitting turning stitch position. After that, the machine head continues to move to the left until the pusher needle C901 is taken away by the knitting triangle, and the knitting turning stitch action is completed.

[0046] See Figure 12 As shown, when the machine head moves to the left, if system 1 needs to lift the needle or attach a needle, the pusher needle C901 needs to be pushed to the lifting and attaching position. Before the machine head moves to the left, when the machine head moves to the right, the machine head moves above the needle selector X902, and the needle selector X902 is lifted by the side lifting needle triangle 3, so that the needle selector X902 is lifted to the working position. At this time, the needle selector blade 22 is in working state. After the machine head continues to move to the right, the needle selector X902 is pressed down by the needle selector blade 222 pressure point 221 and moves along the needle path. When the machine head runs out of the range of the needle selector X902, the machine head starts to move to the left. When moving to the left, the needle selector X902 moves along the needle path. When the needle selector X902 reaches the needle selector 2, the needle selector blade 22 is in the avoidance state, so that the needle selector X902 is pushed by the pusher needle triangle 8 push point 81, which drives the pusher needle C901 into the lifting and attaching position.

[0047] See Figure 13 As shown, when the machine head moves to the left, if system 1 needs to stop knitting, the push long needle C901 needs to be pushed to the stop knitting position. Before the machine head moves to the left, when the machine head moves to the right, the machine head moves above the selector needle X902, and the selector needle X902 is lifted by the side lifting triangle 3, so that the selector needle X902 is lifted to the working position. At this time, the selector blade 22 is in working state. After the machine head continues to move to the right, the selector needle X902 is pressed down by the needle press point 221 of the selector blade 22 and moves along the needle path. When the machine head runs out of the range of the selector needle X902, the machine head starts to move to the left. When moving to the left, the selector needle X902 moves along the needle path. When the selector needle X902 reaches the selector 2, the selector blade 22 is in working state, so that the selector needle X902 is pressed down by the needle press point 221 at the top of the selector blade 22, thus completing the stop knitting.
