Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and in particular to a knitted fabric sewing device and the knitted fabric prepared therefrom. Background Technology

[0002] Currently, Chinese Patent Publication No. CN115652543A discloses a modular operating structure for a sewing machine, including a frame, a worktable on the frame, a Y-axis movement drive mechanism within the worktable, a Y-axis mounting plate, a linear power source I on the upper surface of the Y-axis mounting plate, a mounting base at the output end of the linear power source I, and an X-axis movement drive mechanism on the upper surface of the mounting base. The X-axis movement drive mechanism includes an L-shaped mounting frame, a linear power source II within the L-shaped mounting frame, and a mold clamping plate at the output end of the linear power source II. This discloses the existing modular sewing machine operating components, where the sewing machine relies on the Y-axis and X-axis movement platforms to move the fabric to be sewn below the sewing machine and move it according to the required sewing trajectory. However, existing modular sewing machines, when requiring double-stitched fabric, often involve first sewing one piece of fabric together, and then combining the sewn single piece of fabric with another set of fabric. Modular sewing requires stopping the machine for a second sewing, resulting in low sewing efficiency. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes a knitted fabric sewing device and the knitted fabric prepared therefrom, which solves the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A knitted fabric sewing device includes a knitted fabric sewing mechanism, a first module plate disposed below the knitted fabric sewing mechanism, a first sewing opening disposed on the first module plate, a first limiting plate disposed on the first module plate, pressure strips extending on both sides of the first limiting plate for pressing a cross strip, a first pressure plate disposed on the first limiting plate for pressing an inner bag, a second module plate rotatably connected to the first module plate, a second pressure plate disposed on the second module plate, a flipping mechanism for driving the first module plate to cover the second module plate, and a moving platform for driving the first module plate and the second module plate to move, wherein the pressure strips are spaced apart from the first sewing opening.

[0006] Furthermore, the flipping mechanism includes a first hinge piece connected to the second module plate, a second hinge piece connected to the first module plate and cooperating with the first hinge piece, a first elongated hole on the second module plate, a first half gear rotatably disposed in the first elongated hole, a rotating rod fixed to the bottom of the first half gear, a drive cylinder disposed between the bottom of the second module plate and the rotating rod, a second elongated hole on the first module plate, and a second half gear fixed in the second elongated hole and cooperating with the first half gear. The center of the teeth of the second half gear is rotatably connected to the central axis of the first hinge piece, and the second half gear is connected to the second module plate at a distance from the center.

[0007] Furthermore, the first module plate has a first square hole on the side away from the second module plate, and the second module plate has a second square hole on the side away from the second pressure plate.

[0008] Based on the same inventive concept, a knitted fabric is also proposed, which is prepared using the above-mentioned knitted fabric sewing device. From top to bottom, it includes a first layer of knitted fabric, a waterproof and breathable layer, a second layer of knitted fabric, and a mesh fabric. A horizontal strip is sewn in the middle of the mesh fabric, and an inner bag is sewn on the horizontal strip.

[0009] In preparing the knitted fabric, the first layer of knitted fabric, the waterproof and breathable layer, the second layer of knitted fabric, and the mesh fabric are sequentially input and cut. Then, the horizontal strip and the inner bag are stacked on the first module plate, and the mesh fabric is stacked on the horizontal strip. The first layer of knitted fabric, the waterproof and breathable layer, and the second layer of knitted fabric are then placed on the second module plate. The horizontal strip and the inner bag on the first module plate are sewn together using a knitted fabric sewing device. After completion, the first module plate is flipped over, and the first layer of knitted fabric, the waterproof and breathable layer, the second layer of knitted fabric, and the mesh fabric are sewn together by the knitted fabric sewing device to output the knitted fabric.

[0010] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0011] This knitted fabric sewing device facilitates the sewing of knitted fabrics. It sews the inner pocket, horizontal straps, and mesh fabric on the first module plate, then flips the first module plate. The knitted fabric sewing mechanism then sews together the first layer of knitted fabric, the waterproof and breathable layer, the second layer of knitted fabric, and the outer perimeter of the mesh fabric. The first module plate enables one-time sewing of the spliced ​​fabrics without stopping the machine. The mesh fabric is manually flipped and placed. The second module plate can align with the sewn fabric on the first module plate. This structure avoids the defect that the template knitted fabric sewing mechanism cannot process secondary spliced ​​fabrics in one go. It solves the problem that existing modular knitted fabric sewing mechanisms require machine stops for secondary sewing when sewing double-spun fabrics, resulting in low sewing efficiency.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] refer to Figures 3-7This embodiment provides a knitted fabric sewing device for sewing knitted fabrics. The knitted fabrics include, from top to bottom, a first knitted fabric 1, a waterproof and breathable layer 2, a second knitted fabric 3, and a mesh fabric 4. A horizontal strip 5 is sewn in the middle of the mesh fabric 4, and an inner bag 6 is sewn on the horizontal strip 5.

[0026] This knitted fabric sewing device includes a knitted fabric sewing mechanism 701, a first module plate 702 located below the knitted fabric sewing mechanism 701, a first sewing opening 703 located on the first module plate 702, a first limiting plate 704 located on the first module plate 702, a pressing strip 705 extending on both sides of the first limiting plate 704 for pressing the horizontal strip 5, a first pressing plate 706 located on the first limiting plate 704 for pressing the inner bag 6, a second module plate 708 rotatably connected to the first module plate 702, a second pressing plate 709 located on the second module plate 708, a flipping mechanism for driving the first module plate 702 to cover the second module plate 708, and a moving platform 711 for driving the first module plate 702 and the second module plate 708 to move. The pressing strip 705 and the first sewing opening 703 are spaced apart.

[0027] The second module plate 708 is provided with a second suture opening 720 that overlaps with the first suture opening 703 when the first module plate 702 is flipped. The first suture opening 703 and the second suture opening 720 are U-shaped. The pressure strip 705 has a laterally extending extension plate 721 at the position of the horizontal band 5, which is conducive to pressing and positioning the horizontal band 5 protruding from the position of the first suture opening 703.

[0028] During use, first place the inner bag 6 in the middle of the first module plate 702, then place the horizontal strap 5 at the top of the inner bag 6 at the sewn part, keeping the inner bag 6 and the horizontal strap 5 in the middle of the first module plate 702. Then place the mesh fabric 4 on the horizontal strap 5, and then rotate the first limiting plate 704 to cover the first module plate 702. The pressure strip 705 on the first limiting plate 704 presses down the outer side of the mesh fabric 4 and the horizontal strap 5, and the first pressure plate 706 on the first limiting plate 704 fixes the position of the inner bag 6. Then, sequentially place the first layer of knitted fabric 1, the waterproof and breathable layer 2, and the second layer of knitted fabric 1. The first layer of knitted fabric 3 is placed on the second module plate 708, and then the second pressure plate 709 is rotated to cover the second module plate 708. The second pressure plate 709 covers the outer sides of the first layer of knitted fabric 1, the waterproof and breathable layer 2, and the second layer of knitted fabric 3. Then, the moving platform 711 is activated, and the moving platform 711 moves the position of the horizontal strip 5 on the first module plate 702 below the knitted fabric sewing mechanism 701. The knitted fabric sewing mechanism 701 is activated. After the moving platform 711 drives the first module plate 702 and the second module plate 708 according to the set trajectory, the knitted fabric sewing mechanism 701 will connect the horizontal strip 5 and the inner... Bag 6 is sewn onto mesh fabric 4. Then, the moving platform 711 moves the first module plate 702 away from under the knitted fabric sewing mechanism 701. The flipping mechanism rotates the first module plate 702 180° to cover the second module plate 708. The moving platform 711 moves the first module plate 702 and the second module plate 708, so that the position of the first sewing opening 703 is moved below the knitted fabric sewing mechanism 701. The knitted fabric sewing mechanism 701 starts to operate. The moving platform 711 moves the first module plate 702 according to the shape of the first sewing opening 703, so that the knitted fabric sewing mechanism 701 starts to operate. 1. The first layer of knitted fabric 1, the waterproof and breathable layer 2, the second layer of knitted fabric 3, and the outer perimeter of the mesh fabric 4 are sewn together. The first module plate 702 realizes the sewing of the spliced ​​fabrics. The second module plate 708 can connect to the fabric sewn on the first module plate 702. It is not limited to sewing the inner pocket 6, but can also simultaneously sew the sleeve tabs and decorative blocks. If the decorative block is sewn, the outer perimeter of the decorative block is sewn on the first module plate 702, and then the first module plate 702 is rotated 180° and sewn on the second module plate 708. This structure avoids the defects of secondary splicing of fabrics and cannot be processed in one step by the knitted fabric sewing device.

[0029] The flipping mechanism includes a first hinge piece 712 connected to the second module plate 708, a second hinge piece 713 connected to the first module plate 702 and cooperating with the first hinge piece 712, a first elongated hole 714 on the second module plate 708, a first half gear 715 rotatably disposed in the first elongated hole 714, a rotating rod 716 fixed to the bottom of the first half gear 715, a drive cylinder 717 disposed between the bottom of the second module plate 708 and the rotating rod 716, a second elongated hole 718 on the first module plate 702, and a second half gear 719 fixed in the second elongated hole 718 and cooperating with the first half gear 715. The center of the teeth of the second half gear 719 is rotatably connected to the central axis of the first hinge piece 712, and the second half gear 719 is connected to the second module plate 708 at an offset distance from the center position.

[0030] When the first module plate 702 needs to be flipped, the push rod inside the drive cylinder 717 retracts inward and drives the rotating rod 716 to rotate. The rotating rod 716 drives the first half gear 715 to rotate 90° clockwise. The transmission ratio between the first half gear 715 and the second half gear 719 is 1:2. The first half gear 715 drives the second half gear 719 to rotate. The second half gear 719 synchronously drives the second module plate 708 to rotate 180° and completely fit onto the first module plate 702. There is no need for manual flipping of the second module plate 708 a second time, which is conducive to the butt stitching of the mesh fabric 4 with the first layer of knitted fabric 1, the waterproof and breathable layer 2 and the second layer of knitted fabric 3.

[0031] The first module plate 702 has a first square hole 707 on the side away from the second module plate 708, and the second module plate 708 has a second square hole 710 on the side away from the second pressure plate 709.

[0032] After the mesh fabric 4 is sewn together with the first layer of knitted fabric 1, the waterproof and breathable layer 2, and the second layer of knitted fabric 3, the sewn fabric can be pulled out through the first square hole 707 and the second square hole 710, improving the efficiency of fabric retrieval.

[0033] Located on the right side of the mobile platform 711 is a clamping mechanism 8 for clamping the sewn fabric of the first module plate 702 and the second module plate 708. Below the clamping mechanism 8 is a collection station 9. The clamping mechanism 8 includes a support plate 801, a base 802 located on one side of the support plate 801, a rotating shaft 803 rotatably mounted on the support plate 801, a guide plate 804 fixed to the outside of the rotating shaft 803, a cam disk 805 fixed to the side of the rotating shaft 803 away from the guide plate 804, a motor 806 for driving the cam disk 805 to rotate, an arc-shaped guide groove 807 on the guide plate 804, and a slider 808 slidably mounted on the base 802. A connecting rod 809 is mounted on the slider 808 and engages with the arc-shaped guide groove 807; a first clamping plate 810 and a second clamping plate 811 are rotatably mounted on the side of the slider 808 away from the connecting rod 809; and a spring 812 is mounted between the first clamping plate 810 and the second clamping plate 811. The connecting rod 809 is provided with a sliding groove 813 on the side away from the slider 808 that engages with the rotating shaft 803. The guide plate 804 is provided with a straight guide groove 814 near the rotating shaft 803. The straight guide groove 814 is connected to the arc-shaped guide groove 807. The upper and lower sides of the cam disk 805 are arc-shaped and contact the first clamping plate 810 and the second clamping plate 811.

[0034] Motor 806 drives guide plate 804 and rotating shaft 803 to rotate. Connecting rod 809 gradually slides from the straight guide groove 814 into the arc-shaped guide groove 807. Connecting rod 809 moves towards base 802, driving slider 808, first clamping plate 810 and second clamping plate 811 towards second module plate 708. When connecting rod 809 contacts the arc-shaped guide groove 807 near its tail end, the upper and lower sides of cam disk 805 contact the first clamping plate 810 and second clamping plate 811. The distance between the first clamping plate 810 and second clamping plate 811 on one side of the cam disk 805 increases, and the other side clamps the sewn fabric in the second square hole 710 on the second module plate 708. Then connecting rod 809 contacts the straight guide groove 814, and connecting rod 809 moves away from the first module plate 702. Connecting rod 809 drives the first clamping plate 810 and second clamping plate 811 to move the fabric. As the second module plate 708 moves out of position, and the rotating shaft 803 continues to rotate more than 80°, the cam plate 805 will no longer contact the first clamping plate 810 and the second clamping plate 811. Under the action of the spring 812, the first clamping plate 810 and the second clamping plate 811 will release the fabric, and the fabric will fall into the collection station 9 below. Before use, the top surface of the second layer of knitted fabric 3 in the second module plate 708 can be inserted into the cardboard. The fabric in the first clamping plate 810 and the second clamping plate 811 will remain flat and stacked in the collection station 9. Since there is an opening on one side of the fabric, the cardboard can be pulled out for sewing when the clothes are stitched. After the second module plate 708 is flipped, the moving platform 711 drives the second module plate 708 to move towards the clamping mechanism 8. The clamping mechanism 8 controls the speed of the motor 806. The reciprocating operation can automatically take out the fabric in the second module plate 708. This clamping efficiency is more efficient and faster than manual and pneumatic robotic arms.

[0035] Example 2

[0036] refer to Figures 1 to 2 This embodiment provides a wrinkle-free cold-proof clothing fabric, which includes, from top to bottom, a first knitted fabric 1, a waterproof and breathable layer 2, a second knitted fabric 3, and a mesh fabric 4. A horizontal strip 5 is sewn in the middle of the mesh fabric 4, and an inner pocket 6 is sewn on the horizontal strip 5.

[0037] Both the waterproof and breathable layer 2 and the mesh fabric 4 are existing materials and will not be described in detail here.

[0038] The method for preparing the above-mentioned knitted fabric includes the following steps:

[0039] The first step is to open and remove impurities from polyester fibers and cotton fibers respectively. After that, they are mixed in a ratio of 60% polyester fibers and 40% cotton fibers. After combing and merging, fiber strips are formed. The fiber strips are initially twisted into coarse sand, and then twisted to form blended yarn.

[0040] The second step is to knit the blended yarn into a greige fabric using a loom, and then dye the greige fabric to the desired color using a dyeing machine to form the first layer of knitted fabric 1 and the second layer of knitted fabric 3.

[0041] The third step involves sequentially inputting and cutting the first layer of knitted fabric 1, the waterproof and breathable layer 2, the second layer of knitted fabric 3, and the mesh fabric 4. Then, the horizontal strip 5 and the inner bag 6 are stacked on the first module plate 702, and the mesh fabric 4 is stacked on the horizontal strip 5. The first layer of knitted fabric 1, the waterproof and breathable layer 2, and the second layer of knitted fabric 3 are then placed on the second module plate 708. The horizontal strip 5 and the inner bag 6 on the first module plate 702 are sewn together using the knitted fabric sewing device. After completion, the first module plate 702 is flipped over, and the first layer of knitted fabric 1, the waterproof and breathable layer 2, the second layer of knitted fabric 3, and the mesh fabric 4 are sewn together by the knitted fabric sewing device to output the knitted fabric.

[0042] By cooperating with the first module plate 702 and the second module plate 708 and the knitted fabric sewing mechanism 701, the knitted fabric can be sewn efficiently. Compared with the previous manual sewing of the horizontal strip 5, inner bag 6 and mesh fabric 4, and then sewing other fabric layers, the efficiency is higher.
