Upper and lower three-station double-sided electronic knitting jacquard machine

Abstract

This invention discloses a double-sided electronic jacquard knitting machine with three working positions on the upper and lower discs. The upper disc knitting device includes an upper knitting mechanism, an upper electronic needle selection mechanism, and an upper jacquard piece reset mechanism. The lower disc knitting device includes a lower knitting mechanism, a lower electronic needle selection mechanism, and a lower jacquard piece reset triangle. Through the cooperation of the upper and lower disc knitting devices, this invention freely controls three different needle exit methods for each needle on both discs. This allows the needles on both discs to perform three actions—needle exit, needle pick-up, and needle withdrawal—corresponding to three pattern processes: loop formation, loop gathering, and float. This enables the knitting of jacquard structures on both sides, including loop gathering on both sides, achieving a jacquard effect on both sides. This allows the fabric to exhibit various complex structures such as bird's-eye patterns, reverse perforations, and openwork effects, resulting in a stronger three-dimensional feel.

Description

Technical Field

[0001] This invention relates to the technical field of jacquard knitting machines, and in particular to a three-station double-sided electronic jacquard knitting machine with upper and lower discs. Background Technology

[0002] Commonly available electronic jacquard knitting machines on the market are divided into single-sided and double-sided electronic jacquard knitting machines. The main difference between existing single-sided and ordinary double-sided electronic jacquard knitting machines is that one can only knit single-sided jacquard fabric, while the other can knit double-sided jacquard fabric. Most existing ordinary double-sided electronic jacquard knitting machines use electronic jacquard technology on the back, allowing the front side to be knitted with jacquard weaves, while the back side uses a conventional knitting machine with multiple needle passes for fixed weaves. This results in the back side only being able to knit a very simple weave, limiting the variety of patterns and designs.

[0003] With the development of the textile industry, high-end fabrics with jacquard weaves on both sides have become a trend. More and more double-sided jacquard fabrics require the ability to weave complex large floral patterns, with clear fabric textures, complex and diverse weaves, and good elasticity. The front and back sides also need to be reinforced with yarns to improve the comfort and three-dimensional feel of the fabric. Some fabrics even need to have bird's-eye, double-sided perforated, and double-sided openwork effects. Existing ordinary double-sided electronic knitting jacquard machines cannot weave such double-sided jacquard fabrics, while double-sided electronic knitting jacquard machines with upper and lower discs can weave double-sided jacquard fabrics.

[0004] Currently, double-sided electronic jacquard knitting machines with both upper and lower coils are still relatively rare in the knitting machine industry. Existing double-sided electronic jacquard knitting machines with both upper and lower coils generally only support two pattern processing techniques: upper coil knitting and float yarn. They cannot simultaneously support three pattern processing techniques: upper coil knitting, float yarn, and tuck stitch. This means that such machines cannot achieve the tuck stitch pattern, resulting in a lack of at least three pattern processing effects. This directly prevents jacquard fabrics from achieving complex surface effects such as bird's-eye patterns, back holes, and double-sided openwork. Therefore, developing a device that can support both upper and lower coil knitting techniques (knitting, float yarn, and tuck stitch) will become a development trend for circular knitting machines.

[0005] In view of this, the designer has deeply conceived and actively researched and improved the present invention to address the many shortcomings and inconveniences caused by the imperfect structural design of the existing double-sided electronic knitting jacquard machine with upper and lower discs. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-sided electronic knitting jacquard machine with three stations on the upper and lower discs that can realize three jacquard patterns of weaving, floating yarn, and tuck on both sides, so that the woven fabric has a bird's-eye effect on the front and a hole and hollow effect on the back, and the three-dimensional effect of the fabric is more obvious.

[0007] To achieve the above objectives, the solution of the present invention is:

[0008] A double-sided electronic jacquard knitting machine with three stations on the upper and lower discs includes: an upper three-station knitting device, a lower three-station knitting device, and a central core; the central core has a mounting plate, and the mounting plate has a first step and a second step from the outside to the inside.

[0009] The upper three-station knitting device includes an upper knitting mechanism, an upper electronic needle selection mechanism, and an upper jacquard plate reset mechanism. The upper knitting mechanism includes upper knitting needles, upper center needles, and upper combination cams. The upper electronic needle selection mechanism includes an upper second-station needle selector, an upper third-station needle selector, an upper needle selector cutter, an upper jacquard plate, and an upper needle plate. The upper jacquard plate reset mechanism includes a first upper jacquard plate reset cam, a second upper jacquard plate reset cam, and a third upper jacquard plate reset cam. The upper combination cam includes an upper knitting needle cam, an upper presser cam, and an upper center needle cam. The upper knitting needles, upper center needles, and upper jacquard plates are horizontally placed in the needle grooves of the upper needle plate. The needle connects the upper jacquard piece and the upper knitting needle. An upper combination triangle is placed directly above the upper center needle and the upper knitting needle. The upper combination triangle is installed at the bottom of the outer ring of the upper needle selector cutter block. The upper needle selector cutter block is installed on the second step of the center core. The upper second-position needle selector and the upper third-position needle selector are vertically installed directly above the upper jacquard piece through the upper needle selector cutter block. The second and third reset triangles of the upper jacquard piece are located inside and outside the upper second-position needle selector and the upper third-position needle selector, respectively, and are both installed at the bottom of the upper needle selector cutter block. The first reset triangle of the upper jacquard piece is installed on the first step of the center core.

[0010] The lower three-station knitting device includes a lower knitting mechanism, a lower electronic needle selection mechanism, and a lower jacquard plate reset mechanism. The lower knitting mechanism includes a lower knitting needle, a lower center needle, and a lower combination cam. The lower electronic needle selection mechanism includes a lower second-station needle selector, a lower third-station needle selector, a lower needle selector seat, a lower jacquard plate, and a lower needle cylinder. The lower jacquard plate reset mechanism includes a lower reset cam and a cam seat center plate. The lower combination cam includes a lower knitting needle cam, a lower presser cam, and a lower center needle cam. The lower center needle, lower knitting needle, and lower jacquard plate are vertically placed in the lower needle cylinder. Inside the needle groove, the lower center needle connects to the lower jacquard piece and the lower knitting needle. A lower combination triangle is placed on the outer side of the lower center needle and the lower knitting needle. The lower combination triangle and the lower reset triangle are respectively placed on the upper and lower planes of the triangle seat plate. The end of the lower jacquard piece slides axially in the track of the lower reset triangle to achieve a vertical state from tilting. The lower jacquard piece is tilted by the lower second-position needle selector and the lower third-position needle selector, which drive the lower center needle and the lower knitting needle to perform needle lifting, needle holding and needle closing actions.

[0011] Furthermore, the upper knitting triangle, upper presser triangle, and upper middle needle triangle of the upper combined triangle are formed by stacking three types of triangles and have the track characteristics of the three types of triangles. The track shapes of the upper knitting triangle and the upper middle needle triangle are complementary, that is, the upper part of the track of the upper knitting triangle has an upper path, and the lower part of the track of the upper middle needle triangle has a lower path corresponding to the upper path.

[0012] Furthermore, the upper needle plate is provided with a fan-shaped needle groove, and an upper jacquard piece reset ramp slide and an upper jacquard piece placement groove are provided at the bottom of the needle groove. The upper needle plate is located below the combined triangle, and the upper jacquard piece, upper middle needle, and upper knitting needle are placed in the needle groove respectively.

[0013] Furthermore, the upper jacquard plate is provided with a first reset plate foot, a second reset plate foot, and a needle selection pin. The back of the upper jacquard plate is provided with a raised lifting angle, a reset ramp, and a needle lifting part. Multiple upper jacquard plates have multiple needle selection pins at different positions. The multiple upper jacquard plates are arranged at equal intervals according to the position of the needle selection pins, and respectively correspond to the needle selection knife on the upper second-position needle selector and the upper third-position needle selector. The upper jacquard plates with needle selection pins at different positions are placed in the needle groove of the upper needle plate in sequence.

[0014] Furthermore, the upper needle is provided with a needle holder, a needle holding groove and a lower needle shank. The upper needle is connected through the needle holding groove and the lower needle shank is inserted into the needle holder in the upper jacquard piece.

[0015] Furthermore, one end of the first reset triangle of the upper jacquard piece is provided with a wave-shaped undulating pin reset point, the other end of the second reset triangle of the upper jacquard piece facing the upper two-position needle selector and the upper three-position needle selector is provided with a wave-shaped undulating pin reset point corresponding to the upper jacquard piece, and one end of the third reset triangle of the upper jacquard piece facing the upper two-position needle selector and the upper three-position needle selector is provided with a wave-shaped undulating pressure point corresponding to the upper jacquard piece.

[0016] Furthermore, the upper jacquard piece reset mechanism includes a body for the first reset triangle of the upper jacquard piece, and a raised slide rail for the upper jacquard piece is provided on the first reset triangle of the upper jacquard piece. The first reset triangle of the upper jacquard piece and the second reset triangle of the upper jacquard piece are combined to form a curved track for the upper jacquard piece to move up and down. The third reset triangle of the upper jacquard piece is a wavy curved track corresponding to the second reset triangle of the upper jacquard piece. The multiple curved tracks formed by the first reset triangle of the upper jacquard piece, the second reset triangle of the upper jacquard piece and the third reset triangle of the upper jacquard piece respectively enable the jacquard piece to drive the center needle and the knitting needle to perform needle lifting, needle holding and needle closing actions.

[0017] Furthermore, the upper second-position needle selector and the upper third-position needle selector on the upper needle selector block are positioned between the two curved tracks formed by the first reset triangle, the second reset triangle, and the third reset triangle of the upper jacquard piece. The cutter head on the upper second-position needle selector and the upper third-position needle selector swings left and right to contact or not contact the needle selection bell of the upper jacquard piece, so that the upper jacquard piece forms an up-and-down tilting motion in the upper needle plate.

[0018] Furthermore, the lower needle triangle, lower presser triangle, and lower center needle triangle are formed by overlapping three types of triangles and simultaneously possess the track characteristics of the three types of triangles. The lower needle triangle has an upper path at the top of its track, and the lower center needle triangle has a lower path at the bottom of its track.

[0019] Furthermore, the upper end of the lower jacquard piece is provided with a lower reset needle and a lower push needle, the middle section is provided with a lower selection needle, and the bottom is provided with a lower reset spring placement groove.

[0020] This invention relates to a double-sided electronic jacquard knitting machine with three working positions on the upper and lower discs. Through the cooperation of the upper and lower disc three-position knitting devices, it freely controls three different needle exit methods for each needle on the upper and lower discs. This allows the needles on both the upper and lower discs of the double-sided jacquard knitting circular machine to perform three actions: needle exit, needle pick-up, and needle removal, which correspond to three pattern processes: loop forming, loop gathering, and floating yarn, respectively. It can knit jacquard structures on both sides, and loop gathering structures can be produced on both sides, achieving a jacquard effect with loop gathering on both sides. As a result, the fabric can exhibit various complex structures such as bird's eye, reverse hole, and openwork effects, and the texture and three-dimensionality of the fabric surface can be enhanced.

[0057] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0058] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0059] Please see Figures 1 to 15 As shown, the present invention discloses a three-station double-sided electronic knitting jacquard machine, which includes: an upper three-station knitting device 1, a lower three-station knitting device 2, and a middle core 3.

[0060] The Zhongren 3 has a mounting plate 31, and the mounting plate 31 has a first step 32 and a second step 33 from the outside to the inside.

[0061] The upper three-station knitting device 1 includes an upper knitting mechanism 11, an upper electronic needle selection mechanism 12, and an upper jacquard plate reset mechanism 13. The upper knitting mechanism 11 includes upper knitting needles 111, upper center needles 112, and upper combination cams 113. The upper electronic needle selection mechanism 12 includes an upper two-station needle selector 121, an upper three-station needle selector 122, an upper needle selector cutter 123, an upper jacquard plate 124, and an upper needle plate 125. The upper jacquard plate reset mechanism 13 includes an upper jacquard plate first reset cam 131, an upper jacquard plate second reset cam 132, and an upper jacquard plate third reset cam 133. The upper combination cam 113 includes an upper knitting needle cam 113A, an upper presser cam 113B, and an upper center needle cam 113C. The upper knitting needles 111, upper center needles 112, and upper jacquard plates 124 are horizontally placed in the needle grooves 12 of the upper needle plate 125. Within 5A, the upper center needle 112 connects to the upper jacquard piece 124 and the upper knitting needle 111. An upper combination triangle 113 is placed directly above the upper center needle 111 and the upper knitting needle 112. The upper combination triangle 113 is installed at the bottom of the outer ring of the upper needle selector cutter block 123. The upper needle selector cutter block 123 is installed on the second step 33 of the center core 3. The upper second-position needle selector 121 and the upper third-position needle selector 122 are vertically installed directly above the upper jacquard piece 124 through the upper needle selector cutter block 123. The upper jacquard piece second reset triangle 132 and the upper jacquard piece third reset triangle 133 are located inside and outside the upper second-position needle selector 121 and the upper third-position needle selector 122, respectively, and are both installed at the bottom of the upper needle selector cutter block 123. The upper jacquard piece first reset triangle 131 is installed on the first step 32 of the center core 3.

[0062] The lower three-station knitting device 2 is vertically arranged on the outer side of the bottom of the upper three-station knitting needle device 1. It has a lower knitting mechanism 21, a lower electronic needle selection mechanism 22, and a lower jacquard plate reset mechanism 23. The lower knitting mechanism 21 includes a lower knitting needle 211, a lower center needle 212, and a lower combination cam 213. The lower electronic needle selection mechanism 22 includes a lower second-station needle selector 221, a lower third-station needle selector 222, a lower needle selector seat 223, a lower jacquard plate 224, and a lower needle cylinder 225. The lower jacquard plate reset mechanism 23 includes a lower reset cam 231 and a cam seat center plate 232. The lower combination cam 213 includes a lower knitting needle cam 213A, a lower presser cam 213B, and a lower center needle cam 213C. The lower center needle 212 and lower knitting needle 211... 1. The lower jacquard piece 224 is vertically placed in the needle groove of the lower needle cylinder 225. The lower center needle 212 connects the lower jacquard piece 224 and the lower knitting needle 211. The lower combination triangle 213 is placed on the outer side of the lower center needle 212 and the lower knitting needle 211. The lower combination triangle 213 and the lower reset triangle 231 are respectively placed on the upper and lower planes of the triangle seat plate 232. The end of the lower jacquard piece 224 slides axially in the track of the lower reset triangle 231, which can realize the return from the tilted state to the vertical state. The lower jacquard piece 224 is pushed to tilt by the lower second position needle selector 221 and the lower third position needle selector 222, which drives the lower center needle 212 and the lower knitting needle 211 to perform needle lifting, needle holding and needle closing actions.

[0063] Figure 2A and Figure 2B The diagram shows the structure of the upper combined triangle 113. The upper knitting needle triangle 113A, the upper presser needle triangle 113B, and the upper center needle triangle 113C are formed by overlapping three types of triangles and have the track features 113D, 113E, and 113F of the three types of triangles. The track shapes of the upper knitting needle triangle 113A and the upper center needle triangle 113C are complementary. That is, the upper part of the track 113D of the upper knitting needle triangle 113A has an upper path, and the lower part of the track 113F of the upper center needle triangle 113C has a lower path corresponding to the upper path. During the knitting process, the upper path of the upper knitting needle triangle 113A and the lower path of the center needle triangle 113C play the main guiding role. The upper needle triangle 113A and the upper presser triangle 113B control the upper needle 112 to retract, while the upper center needle triangle 113C controls the upper needle 111 to extend. The upper presser triangle 113B is mainly used to adjust the size of the fabric yarn loops during knitting. During the jacquard process, the upper presser triangle 113B does not participate in the action.

[0064] like Figure 3 The diagram shows the structure of the upper needle plate 125. The upper needle plate 125 is provided with a fan-shaped needle groove 125A. At the bottom of the needle groove 125A, there is an upper jacquard piece reset ramp slide 125B and an upper jacquard piece placement groove 125C.

[0065] like Figure 4The diagram shows the combined structure of the upper jacquard piece 124, the upper center needle 112, and the upper knitting needle 111. The upper center needle 112 is provided with a needle bar 112A, a needle holding groove 112B, and a lower needle shank 112C. The upper knitting needle 111 is connected through the needle holding groove 112B, and the lower needle shank 112C is inserted into the needle-lifting part 124F in the upper jacquard piece 124. In this way, the upper center needle 112, the upper knitting needle 111, and the upper jacquard piece 124 can be linked together.

[0066] like Figures 5A to 5C The diagram shows the structure of the upper jacquard plate 124 of the needle selection pin 124C in three different positions. The upper jacquard plate 124 is provided with a first reset plate foot 124A, a second reset plate foot 124B and a needle selection pin 124C. The back of the upper jacquard plate 124 is provided with a raised lifting angle 124D, a reset ramp 124E and a needle lifting part 124F. Multiple jacquard pieces 124 have multiple needle selectors 124C at different positions. These jacquard pieces are arranged at equal intervals according to the positions of the needle selectors 124C, corresponding to the needle selectors on the upper second-position needle selector 121 and the upper third-position needle selector 122, respectively. The jacquard pieces 124 with needle selectors 124C at different positions are placed sequentially in the fan-shaped needle grooves 125A of the upper needle plate 125. Through the action of the triangular tracks of the upper second-position needle selector 121, the upper third-position needle selector 122, and the combined cam 113, the corresponding knitting actions are completed. The upper needle plate 125 is located below the combined cam 113, and the fan-shaped needle grooves 125A of the upper needle plate 125 respectively hold the jacquard pieces 124, the upper center needle 112, and the upper knitting needle 111.

[0067] like Figure 6A and Figure 6B The diagram shows the installation structure of the upper electronic needle selection mechanism 12 and the upper jacquard plate reset mechanism 13. The upper jacquard plate reset mechanism 13 includes an upper jacquard plate first reset triangle 131, an upper jacquard plate second reset triangle 132, and an upper jacquard plate third reset triangle 133. The upper jacquard plate first reset triangle 131, through the tracks of the three upper jacquard plate reset triangles 131, 132, and 133 and the special structure of the upper needle plate 125, enables the upper jacquard plate 124 to complete the reset action, restoring the upper jacquard plate 124 and the upper center needle 112 to their initial positions, so that the needle selection action can be performed cyclically.

[0068] like Figure 7A and Figure 7B As shown, one end of the first reset triangle 131 of the upper jacquard piece is provided with a wavy, undulating pin reset point 132A, as... Figure 7C As shown, the second reset triangle 132 of the upper jacquard piece has a wave-shaped undulating pin reset point 132A corresponding to the upper jacquard piece 124 at the other end of the upper two-position needle selector 121 and the upper three-position needle selector 122. Figure 7DAs shown, the third reset triangle 133 of the upper jacquard piece has a wave-shaped undulating needle pressing point 133A corresponding to the upper jacquard piece 124 at one end facing the needle selector 121 of the upper second position and the needle selector 122 of the upper third position. Specifically, the first reset triangle 131 of the upper jacquard piece of the upper jacquard piece reset mechanism 13 includes a body and an upper jacquard piece protruding slide 131A set on the body. The first reset triangle 131 and the second reset triangle 132 of the upper jacquard piece are combined to form a curved track for the upper jacquard piece 123 to move up and down. The third reset triangle 133 of the upper jacquard piece corresponds to the wave-shaped undulating curved track of the second reset triangle 132 of the upper jacquard piece. The multiple curved tracks formed by the first reset triangle 131, the second reset triangle 132 and the third reset triangle 133 of the upper jacquard piece respectively enable the jacquard piece to drive the center needle and the knitting needle to perform needle insertion, needle holding and needle removal actions. The upper second-position needle selector 121 and upper third-position needle selector 122 on the upper needle selector cutting block 123 are positioned between the two curved tracks formed by the upper jacquard plate's first reset triangle 131, upper jacquard plate's second reset triangle 132, and upper jacquard plate's third reset triangle 133. The cutting heads on the upper second-position needle selector 121 and upper third-position needle selector 122 can swing left and right to contact or not contact the needle selection bell 124C of the upper jacquard plate 124, causing the upper jacquard plate to form an up-and-down tilting motion in the upper needle plate 125.

[0069] The upper jacquard piece 124's first reset triangle 131 slides to the corresponding upper jacquard piece's second reset triangle 132's wavy undulating pin reset point 132A. The reset principle of the upper jacquard piece 124 is as follows: Figures 8A to 8C As shown in Figure A, the third reset triangle 133 of the upper jacquard piece presses the upper jacquard piece 124 onto the center of the upper needle plate 125 via the first reset foot 124A. The upper jacquard piece 124 moves towards the center of the upper needle plate 125 via the first reset foot 124B under the action of the third reset triangle 133. At this time, the upper jacquard piece 124 is lifted by the upper jacquard piece reset ramp slide 125B of the upper needle plate 125. Figure 8B As shown, after the third reset triangle 133 presses the second reset tab 124B of the upper jacquard piece 124 to the bottom, the back protrusion lifting angle 124D on the upper jacquard piece 124 is completely lifted by the upper jacquard piece reset ramp slide 125B, at which point the upper center pin 112 is completely reset. Figure 8C As shown, the first reset foot 124A of the upper jacquard piece 124 is pushed out by the second reset triangle 132 of the upper jacquard piece and moves towards the outer diameter of the upper needle plate 125. At the same time, the first reset triangle 131 of the upper jacquard piece lifts the tail of the upper jacquard piece 124 through the raised slide 131A of the upper jacquard piece. The second reset triangle 132 of the upper jacquard piece is above the first reset triangle 131 of the upper jacquard piece, which can prevent the upper jacquard piece 124 from being thrown out of the upper needle plate 125 when it is pushed out. The entire reset action is completed.

[0070] Through the cooperation of the upper knitting mechanism 11, the upper electronic needle selection mechanism 12 and the upper jacquard plate reset mechanism 13, the three movement modes of each upper needle 111 can be freely controlled, so that the upper plate of the double-sided jacquard knitting circular machine can realize the three actions of needle release, needle pick-up and needle take-off, which correspond to the three pattern processes of loop forming, loop gathering and floating yarn respectively.

[0071] The second reset triangle 132 of the upper jacquard piece faces the needle selector 121 at the upper second position and the needle selector 122 at the upper third position. The other end of the needle selector 122 is provided with a wave-shaped undulating pin reset point 132A corresponding to the upper jacquard piece 124. The upper jacquard piece raised slide 131A of the first reset triangle 131 of the upper jacquard piece corresponds to the wave-shaped undulating pin reset point 132A on the second reset triangle 132 of the upper jacquard piece. The wave-shaped undulating curve track of the third reset triangle 133 of the upper jacquard piece presses the upper jacquard piece to the center of the needle plate 125 through the first reset piece foot 124A. The upper jacquard piece 124 moves to the center of the needle plate 125 through the first reset piece foot 124A under the action of the third reset triangle 133 of the upper jacquard piece. The upper jacquard piece 124 is lifted by the action of the upper jacquard piece reset ramp slide 125. After the third reset triangle 133 of the upper jacquard piece presses the second reset foot 124B of the upper jacquard piece 124 to the bottom, the raised lifting angle 124D on the back of the upper jacquard piece 124 is completely lifted by the upper jacquard piece reset ramp slide 125, and the upper center needle 112 is completely reset. The first reset foot 124A of the upper jacquard piece 124 is pushed out by the second reset triangle 132 of the upper jacquard piece and moves towards the outer diameter of the upper needle plate 125. At the same time, the first reset triangle 131 of the upper jacquard piece lifts the tail of the upper jacquard piece 124 through the jacquard piece raised slide 131A. The second reset triangle 132 of the upper jacquard piece is above the first reset triangle 131 of the upper jacquard piece, which can prevent the upper jacquard piece 124 from being thrown out of the upper needle plate 125 when it is pushed out. This structure is simple, low-cost and does not bring any negative effects. It can also increase the rotation speed of the knitting machine, thereby increasing the production capacity.

[0072] like Figure 9A and Figure 9B The diagram shown is a schematic diagram and principle diagram of the float yarn output action of the three-position needle device on the upper plate. Figure 9A When the upper needle 111 is in the flat needle position, the needle selector blade of the upper second-position needle selector 121 swings, pressing down the needle selector heel 124C of the upper jacquard plate 124. Under the downward pressure and the fulcrum of the upper reset triangle, the upper jacquard plate 124 tilts downward, simultaneously causing the upper center needle 112 to tilt. The needle heel 112A of the upper center needle 112 disengages from the track 113F of the center needle triangle 113C and is pressed into the upper needle plate 125. The center needle triangle 113C loses its needle-leading function, and the upper needle 111 will not perform needle movement along the track 113A of the upper needle triangle. Figure 9BAs the upper needle 111 continues to move in a circular motion along the upper needle triangle 113A, the upper presser triangle 113B resets the upper needle 112 to its initial position, and the next cycle begins again.

[0073] like Figure 9C and Figure 9D The diagram shown is a schematic diagram and principle diagram of the three-position needle device on the upper plate for the knitting loop production action. Figure 9C When the upper needle 111 is in the half-needle position, the needle selector blade of the upper three-position needle selector 122 swings, pressing down the needle selector heel 124C of the upper jacquard plate 124. Under the downward pressure and the fulcrum of the upper reset triangle, the upper jacquard plate 124 tilts downward, simultaneously causing the upper center needle 112 to tilt. The needle heel 112A of the upper center needle 112 disengages from the track 113F of the center needle triangle 113C at the half-needle position and is pressed into the upper needle plate 125. The center needle triangle 113C loses its needle-out function, and the upper needle 111 will not make needle movement along the track of the upper needle triangle 113A. Figure 9D As the upper needle 111 continues to move in a circular motion along the upper needle triangle 113A, the presser triangle 13B resets the upper needle 112 to its initial position, and the next cycle begins again.

[0074] like Figure 9E and Figure 9F The diagram shown is a schematic diagram and principle diagram of the loop-forming action of the three-position needle device on the upper plate. Figure 9E When the upper jacquard piece 124 passes the plain stitch position, the needle selectors 121 (second position), 122 (third position), and 21 (second position) do not move. Therefore, the center needle 112 will complete a full needle exit motion along the track 113F of the center needle triangle 113C, pushing the upper needle 111 to complete the loop formation. For example... Figure 9F As the upper needle 111 continues to move in a circular motion along the upper needle triangle, the upper presser triangle 113B resets the upper needle 111 to its initial position and restarts the next cycle.

[0075] like Figure 10 The diagram shows the combined structure of the lower combination triangle 213. The lower knitting needle triangle 213A, lower presser needle triangle 213B, and lower center needle triangle 213C are formed by stacking three conventional triangles and simultaneously possess the track features 213D, 213E, and 213F of the three triangles. The upper part of the track 213D of the lower knitting needle triangle 213A has an upper path, and the lower part of the track 213F of the lower center needle triangle 213C has a lower path. During the knitting process, the upper path of the lower knitting needle triangle 213A and the lower path of the lower center needle triangle 213C play a major guiding role. The lower knitting needle triangle 213A and the presser needle triangle 213B control the retraction of the lower knitting needle 211, while the lower center needle triangle 213C controls the extension of the lower knitting needle 211. The lower presser needle triangle 213B is mainly used to adjust the size of the fabric yarn loops during knitting. During the jacquard process, the lower presser needle triangle 213B does not participate in the action.

[0076] like Figures 11A to 11C The diagram shows a multi-piece jacquard structure. The upper end of the jacquard piece 224 is provided with a lower reset pin 224A and a lower push pin portion 224B, the middle section has a lower selection pin 224C, and the bottom has a lower reset spring placement groove 224D. Multiple jacquard pieces 224 have selection pins 224C in different positions. Through the special structure of the upper lower reset pin 224A and the lower jacquard piece reset mechanism 23, the lower jacquard piece 224 completes its reset action. The lower combination triangle 213 and the lower reset triangle 231 are respectively placed on the upper and lower planes of the triangle base plate 232. The lower reset pin 224A at the upper end of the lower jacquard piece 224 is placed in the track 231A of the lower reset triangle 231. Figure 12 The diagram shows a lower reset triangle structure. The lower reset triangle 231 has a track 231A. The lower jacquard piece 224 slides axially in the track 231A of the lower reset triangle 231, which can realize the reset from the tilted state to the vertical state. The lower jacquard piece is pushed by the lower second-position needle selector 221 and the lower third-position needle selector 223 to tilt the lower jacquard piece 224, thereby driving the lower center needle 212 and the lower knitting needle 211 to perform needle lifting, needle holding and needle closing actions.

[0077] like Figure 13A and Figure 13B The diagram shown is a schematic diagram and principle diagram of the float yarn output action of the three-position knitting needle device in the lower section. Figure 13A When the lower needle 211 is in the flat needle position, the needle selector 221 of the lower second position needle selector swings, pushing the lower heel 224C of the lower jacquard plate 224 towards the cylinder axis. Under the pushing force and the action of the lower reset needle foot 224A of the lower jacquard plate 224, the lower jacquard plate 224 tilts inward towards the lower cylinder 225, simultaneously causing the lower center needle 212 to tilt. The heel 212A of the lower center needle 212 disengages from the track 213F of the lower center needle triangle 213C and is pressed into the lower cylinder 225. The lower center needle triangle 213C loses its needle-out function, and the lower needle 211 will not make needle movement along the lower needle triangle 213A. Figure 13B As the lower needle 211 continues to move in a circular motion along the lower needle triangle 213A, the lower presser triangle 213B resets the lower needle 211 to its initial position, and the next cycle begins again.

[0078] like Figure 13C and Figure 13D The diagram shown is a schematic diagram and principle diagram of the three-position knitting needle device in the lower section for the knitting loop production process. Figure 13CWhen the lower needle 211 is in the half-needle position, the needle selector blade of the lower three-position needle selector 222 swings, pushing the lower needle selector heel 224C of the lower jacquard plate 224 towards the cylinder axis. Under the action of the pushing force and the lower reset needle foot 224A of the lower jacquard plate 224, the lower jacquard plate 224 tilts inward towards the lower cylinder 225, simultaneously causing the lower center needle 212 to tilt. The needle heel 212A of the center needle 212 disengages from the lower center needle triangle 213C track 213F at the half-needle position and is pressed into the lower cylinder 225. The lower center needle triangle 213C loses its needle-out function, and the lower needle 211 will not make needle movement along the lower needle triangle 213A. Figure 13D As the lower needle 211 continues to move in a circular motion along the lower needle triangle 213A, the lower presser triangle 213B resets the lower needle 211 to its initial position, and the next cycle begins again.

[0079] like Figure 13E and Figure 13F The diagram shown is a schematic diagram and principle diagram of the loop-forming action of the three-station knitting needle device on the lower plate. Figure 13E When the jacquard piece 224 passes through the plain stitch position, and the needle selectors 221 and 222 at the second and third positions do not move, the center needle 212 will make a complete needle exit motion along the track 213F of the center needle triangle 213C, pushing the lower needle 211 to complete the loop formation motion. For example... Figure 13F As the lower needle 211 continues to move in a circular motion along the upper needle triangle 213A, the lower presser needle triangle 213B resets the lower needle 211 to its initial position, and the next cycle begins again.

[0080] Figure 14 This is a 3D effect diagram of the knitting needle action when the upper knitting needle comes out to form a loop and the lower knitting needle comes out to form a circle. It can show the needle release state of the upper and lower knitting needles. This needle release method can create holes or mesh on the reverse side of the fabric, enhancing the three-dimensional effect of the fabric on the back.

[0081] Figure 15 This is a 3D effect diagram of the simultaneous tuck stitch action of the upper and lower knitting needles. It can show the needle exit state of the upper needle 111 and the lower needle 211. This needle exit method can create bird's-eye and hollow effects on the fabric, enhancing the three-dimensional effect of the fabric on both sides.

[0082] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
