Description

Technical field

[0001] The invention relates to the technical field of textile processing, in particular to a jacquard piece and a double-sided computerized fine-needle jacquard device thereof. [Background Technology]

[0002] There are many types of textiles, and jacquard fabrics are one of them. Jacquard fabrics are a concave and convex pattern formed by interlacing warp and weft threads. Jacquard fabrics can be divided into home textile materials and fashion materials. Jacquard devices are used for jacquard fabric processing and usually include a double-sided computerized upper jacquard device and a double-sided computerized lower jacquard device. Existing double-sided computerized upper jacquard devices have the following shortcomings:

[0003] 1. Due to the complexity of the design, the jacquard machine is not stable enough during operation, which makes the equipment unable to run normally at high speed, resulting in low production efficiency and high processing costs. In addition, the operation is cumbersome and requires high standards from industry practitioners.

[0004] 2. The jacquard pattern design of existing double-sided computerized upper jacquard devices all has a straight-line structure and must be located in the same needle groove as the middle needle and upper disc needles. This length restricts its use on machines with high-gauge needle counts (it can only be used on machines with gauges below 30 needles; for example, the upper jacquard pattern in existing patent CN104109936B is located below the upper needle selector and has a straight-line structure). However, existing double-sided lower jacquard devices are already widely used on high-gauge machines, making the upper jacquard device unable to keep up with the existing double-sided computerized lower jacquard devices, leaving a significant gap in the high-end home textile and fashion markets.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Summary of the invention]

[0006] The present invention aims to solve the technical problems existing in the existing double-sided computer upper jacquard device, and is to provide a jacquard piece and a double-sided computer high-stitch jacquard device thereof. By improving the shape of the jacquard piece, the length of the jacquard piece is greatly reduced, and the space occupied by the jacquard piece in the horizontal length direction is greatly shortened. The length constraint of the traditional "I"-shaped jacquard piece in the upper needle disc is broken through, so that the upper jacquard device can adapt to a high-density stitch length of 18-38 needles.

[0007] The present invention is achieved as follows: a jacquard piece, the jacquard piece adopts a Z-shaped structural design, and the jacquard piece includes a vertically arranged main body piece; a left wing plate is extended from the left side of the upper part of the main body piece, and a circular lever fulcrum for cooperating with the upper jacquard needle disk is provided on the left side of the left wing plate; a plurality of stitches are provided on the right side of the middle part of the main body piece; a right wing plate is extended from the right side of the lower part of the main body piece, and a bayonet for cooperating with the middle needle is formed inwardly on the right side of the right wing plate.

[0008] Furthermore, the number of the pins is 8 or 12.

[0009] On the other hand, a double-sided computerized fine stitch upper jacquard device using the jacquard piece also includes an upper jacquard needle dial, and a card slot for a circular lever fulcrum to be inserted and a first give-way needle slot for the main body piece to rotate are formed on the side of the upper jacquard needle dial facing the jacquard piece, and the first give-way needle slot is located below the card slot.

[0010] Furthermore, it also includes an upper needle disk, an intermediate needle, an upper disk knitting needle, an upper disk triangle, an upper cutting disk, a needle selector, a middle core bracket, and a reset triangle; the left end of the upper needle disk is vertically connected to the bottom of the upper jacquard needle disk, and a second yielding needle groove for the middle needle and the right wing plate to rotate is formed on the upper part of the upper needle disk; the left end of the middle needle is inserted into the bayonet, and the right end overlaps with the upper disk knitting needle, and the upper surface of the middle needle is provided with a first protrusion; the upper disk triangle is assembled between the upper needle disk and the upper cutting disk, and the lower surface of the upper disk triangle is provided with a first groove for inserting the first protrusion and a second groove for inserting the second protrusion; a step is provided in the middle of the upper cutting disk; the needle selector is assembled on the step, and a plurality of knife heads for side pressing stitches are fixed on the left side of the needle selector; the right side of the middle core bracket is connected to the upper cutting disk; the reset triangle is assembled at the bottom right side of the middle core bracket, the top of the main body is provided with a third protrusion, and the bottom surface of the reset triangle is provided with a third groove matching the third protrusion.

[0011] Furthermore, a second protrusion is provided on the middle upper surface of the upper disk knitting needle.

[0012] Furthermore, the left end of the upper needle dial is vertically connected to the bottom of the upper jacquard needle dial through a first bolt assembly.

[0013] Furthermore, the needle selector is detachably connected to the upper cutting disc via a second bolt assembly.

[0014] Furthermore, the upper cutting disc is detachably connected to the middle core bracket via a third bolt assembly.

[0015] Furthermore, the reset triangle is detachably connected to the center core bracket via a fourth bolt assembly.

[0016] Furthermore, it also includes a computer control system for controlling the swing direction of the needle selector cutter head.

[0017] The advantages of the present invention are:

[0018] 1. The "Z"-shaped structure of the jacquard disc: By improving the shape of the jacquard disc, its length and horizontal space are significantly reduced. This breaks the length constraint of the traditional "I" jacquard disc in the upper needle disc's clearance slot, allowing the upper jacquard mechanism to adapt to high-density gauges of 18-38 needles, thus resolving the high-density gauge limitation of the upper jacquard mechanism. The jacquard disc forms a stable rotating fulcrum system with the upper jacquard needle disc through a circular lever fulcrum. These two technical means work together to simplify the overall structure of the existing upper jacquard mechanism, reduce vibration during high-speed operation, and improve jacquard stability.

[0019] 2. The double-sided computerized high-gauge jacquard device utilizes a Z-shaped jacquard disc, an L-shaped needle dial, and an adjustable needle selector to collaboratively address three key technical bottlenecks: high-gauge adaptability, operational stability, and production efficiency. The upper and lower jacquard devices can simultaneously produce double-sided jacquard patterns, resulting in high processing efficiency. The coordinated operation of the various components of the double-sided computerized high-gauge jacquard device enables flexible switching between weaving and non-weaving states.

[Specific implementation method]

[0033] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] See also Figure 1 As shown, the present invention provides a jacquard piece 1, which adopts a Z-shaped structural design. The jacquard piece 1 includes a vertically arranged main body piece 11; a left wing plate 12 is extended from the left side of the upper part of the main body piece 11, and a circular lever fulcrum 13 for cooperating with the upper jacquard needle disk 2 is provided on the left side of the left wing plate 12; a plurality of stitches 14 are provided on the right side of the middle part of the main body piece 11; a right wing plate 15 is extended from the right side of the lower part of the main body piece 11, and a bayonet 16 for cooperating with the middle needle 4 is formed inwardly on the right side of the right wing plate 15.

[0035] The jacquard sheet 1 of the present invention has the following beneficial technical effects through the "Z"-shaped structural design:

[0036] 1. By improving the shape of the jacquard piece 1, the length of the jacquard piece 1 is greatly reduced, and the space occupied by the jacquard piece 1 in the horizontal length direction is greatly shortened. This breaks through the length constraint of the traditional "I"-shaped jacquard piece in the second clearance groove 31 of the upper needle plate 3, allowing the upper jacquard device to adapt to a high-density needle pitch of 18-38 needles, thus solving the high-density needle pitch limitation of the upper jacquard device.

[0037] 2. The jacquard piece 1 forms a stable rotating fulcrum system with the upper jacquard needle disc 2 through the circular lever fulcrum 13. These two technical means work together to simplify the overall structure of the existing upper jacquard device, reduce vibration during high-speed operation, and improve jacquard stability.

[0038] In the present invention, the number of pins 14 is 8 or 12. The 12-pin design matches the 12-knife needle selector 8, supporting complex patterns; the 8-pin design matches the 8-knife needle selector 8, meeting basic needs. The number of pins 14 on the jacquard piece 1 corresponds to the space reserved for the blade 81 of the needle selector 8, making it directly compatible with two-station or three-station needle selectors 8.

[0039] See also Figures 1 to 11 As shown, the present invention further provides a double-sided computerized fine-gauge upper jacquard device using the jacquard piece 1, further comprising an upper jacquard needle dial 2. The upper jacquard needle dial 2 has a slot 21 on the side facing the jacquard piece 1 for engaging the circular lever fulcrum 13 and a first clearance slot 22 for rotating the main piece 11. The first clearance slot 22 is located below the slot 21. The slot 21 is used to secure the circular lever fulcrum 13, ensuring the stability of the rotation center of the jacquard piece 1. The first clearance slot 22 provides physical space for the main piece 11 to swing, avoiding interference with the upper jacquard needle dial 2.

[0040] In the present invention, it also includes an upper needle disc 3, a middle needle 4, an upper disc knitting needle 5, an upper disc cam 6, an upper cutting disc 7, a needle selector 8, a middle core bracket 9, and a reset cam 10.

[0041] The left end of the upper needle dial 3 is vertically connected to the bottom of the upper jacquard needle dial 2, and a second yielding needle groove 31 for the rotation of the middle needle 4 and the right wing plate 15 is formed on the upper part of the upper needle dial 3; the upper jacquard needle dial 2 and the upper needle dial 3 are connected in a "90° L-shaped structure". This layout further controls the length and realizes the upper jacquard of the machine with high-density needle pitch.

[0042] The left end of the middle needle 4 is inserted into the bayonet 16 and the right end is overlapped with the upper knitting needle 5. A first protrusion 41 is provided on the upper surface of the middle portion of the middle needle 4.

[0043] A second protrusion 51 is provided on the middle upper surface of the upper knitting needle 5 .

[0044] The upper disc triangle 6 is assembled between the upper needle disc 3 and the upper cutting disc 7. The lower surface of the upper disc triangle 6 is provided with a first groove 61 for inserting the first protrusion 41 and a second groove 62 for inserting the second protrusion 51 of the upper disc knitting needle 5; the double groove design ensures that the middle needle 4 and the upper disc knitting needle 5 are controlled separately.

[0045] The upper cutting disc 7 has a step 71 in the middle, and the needle selector 8 is mounted on the step 71. A plurality of cutting heads 81 for side-pressing the stitches 14 are fixed to the left side of the needle selector 8. The connection between the needle selector 8 and the upper cutting disc 7 allows the needle selection position to be adjusted forward, backward, and upward, thereby selecting the most effective jacquard pattern position, eliminating defects in the products processed by the device and ensuring quality.

[0046] The right side of the middle kernel support 9 is connected to the upper cutting disc 7 .

[0047] The reset triangle 10 is assembled at the right bottom of the middle core bracket 9 , a third protrusion 17 is provided on the top of the main body piece 11 , and a third groove 101 is provided on the bottom surface of the reset triangle 10 to cooperate with the third protrusion 17 .

[0048] In the present invention, the left end of the upper needle disc 3 is vertically connected to the bottom of the upper jacquard needle disc 2 via a first bolt assembly. The needle selector 8 is detachably connected to the upper cutting disc 7 via a second bolt assembly. This allows for vertical and horizontal adjustment, allowing for fine-tuning of the contact position between the cutter head 81 and the stitches 14 of the jacquard pattern sheet 1, optimizing needle selection accuracy. The upper cutting disc 7 is detachably connected to the center core bracket 9 via a third bolt assembly. The reset cam 10 is detachably connected to the center core bracket 9 via a fourth bolt assembly. This allows for partial replacement of damaged components, preventing the entire machine from being scrapped.

[0049] The present invention also includes a computer control system for controlling the swing direction of the cutter head 81 of the needle selector 8.

[0050] The upper jacquard device of the present invention has the following beneficial technical effects:

[0051] 1. The Z-shaped jacquard pattern, L-shaped needle plate layout, and adjustable needle selector design work together to address the three major technical bottlenecks of high-density needle pitch adaptability, operational stability, and production efficiency. The upper and lower jacquard patterns can be processed together to produce double-sided jacquard patterns, achieving high processing efficiency.

[0052] 2. All components work together to achieve flexible switching between weaving and non-weaving states. Figure 10 As shown, the computer control system controls the swing direction of the cutter head 81 of the needle selector 8. When the cutter head 81 swings to the same position as the stitch 14, the cutter head 81 presses the stitch 14 sideways, and the main body 11 and the stitch 14 fall into the first yielding needle groove 22. At the same time, the right wing plate 15 presses down, and the first protrusion 41 of the middle needle 4 is separated from the first groove 61 and pressed into the second yielding needle groove 31. At this time, the middle needle 4 does not contact the upper cam 6, and the upper jacquard device is in a non-weaving state. As shown in the attached figure Figure 11 As shown, the jacquard piece 1 resets the stitches 14 to their original positions through the reset triangle 10 at the right bottom of the center support 9, and the right wing plate 15 drives the first protrusion 41 to reinsert into the first groove 61. At this time, the upper jacquard device is in a weaving state.
