Description
Technical Field
[0001] This utility model relates to the field of jacquard machine technology, specifically a jacquard machine for silk fabric. Background Technology
[0002] Silk fabric, with its soft and smooth texture, excellent breathability, and elegant luster, has become the preferred fabric for high-end clothing, home textiles, and other fields. Jacquard weaving is an important technique in the processing of silk fabric, enabling the creation of various exquisite patterns and textures.
[0003] A search of Chinese utility model patent (publication number CN220846445U) reveals a jacquard machine for silk fabric, including a worktable, a first sliding rail, a sliding rod, a second sliding rail, a sliding fabric spreading structure, and a lifting rod. This technical solution can maximize the stretching of the fabric and ensure that the jacquard operation of silk fabric is carried out quickly.
[0004] However, through exploration, the inventors have discovered that this technical solution still has at least the following defects:
[0005] In traditional jacquard machines, the straight-line sliding during the fabric spreading process can cause uneven tension in certain parts of the fabric, especially at the edges or corners, affecting the jacquard effect. Summary of the Invention
[0006] The present invention aims to provide a jacquard machine for silk fabrics to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A jacquard knitting machine for silk fabric includes a base, a worktable connected to the base, a robotic arm connected to the worktable, a jacquard structure connected to the robotic arm, a sliding rod slidably connected to the worktable, a horizontal plate connected to the sliding rod, a slider slidably connected to the horizontal plate, and a fabric spreading device connected to the slider. The fabric spreading device includes a connecting block connected to the slider, a stepper motor connected to the connecting block, a worm gear connected to the output end of the stepper motor, the worm gear rotatably connected to the connecting block, a rotating shaft rotatably connected to the connecting block, a worm wheel connected to the rotating shaft, the worm wheel meshing with the worm gear, a rotating block connected to the rotating shaft, an electric telescopic rod connected to the rotating block, a pressing plate connected to the telescopic end of the electric telescopic rod, and a pressing base plate connected to the rotating block, the pressing plate and the pressing base plate cooperating with each other. Adjustment devices are respectively connected to the worktable and the horizontal plate for adjusting the spacing.
[0009] Preferably, the adjusting device includes a dual-axis motor connected to the worktable, a screw connected to the output end of the dual-axis motor, the screw being rotatably connected to the worktable, a sliding rod being movably connected to the screw, a sliding groove being provided on the worktable, and the sliding rod being slidably connected to the sliding groove. The connection method between the adjusting device and the cross plate is the same as the connection method between the adjusting device and the worktable.
[0010] Preferably, the pressing plate and the pressing base plate are each connected with a rubber pad.
[0011] Preferably, the base is connected to a shock-absorbing pad.
[0012] Preferably, the workbench is connected to a controller, and the robotic arm, jacquard structure, stepper motor, electric telescopic rod and dual-axis motor are electrically connected to the controller.
[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:
[0014] This solution, by incorporating stepper motors, worm gears, and worm wheels, precisely controls the rotation of the rotating block, pressing plate, and pressing base plate, enabling comprehensive adjustments to the silk fabric. During the unfolding process, the tension in different directions can be flexibly adjusted according to the actual condition of the fabric, allowing it to spread out more smoothly and effectively reducing wrinkles and twisting, thus providing a good foundation for subsequent jacquard operations. Uniform fabric tension ensures that the fabric remains stable throughout the jacquard process. The robotic arm and jacquard structure can operate precisely on the fabric according to a preset program, resulting in clearer and more accurate lines in the jacquard pattern, richer details, improved precision and quality of jacquard products, reduced defect rates and waste, and meeting market demand for high-quality silk jacquard products. By setting up sliders and sliding rods—the sliders sliding on the horizontal plate and the sliding rods sliding on the worktable—the fabric can be unfolded in multiple dimensions, allowing it to spread out smoothly and providing an ideal foundation for jacquard. Compared to traditional unfolding methods, this is more efficient and precise, reducing manual adjustments and improving production efficiency.
[0015] By setting an adjustment device, it can be adapted to silk fabrics of different sizes. Whether it is small-scale fine processing or large-scale mass production, it can easily cope with the needs, greatly enhancing the applicability of the jacquard machine, meeting diverse production needs, and reducing the situation where the equipment cannot be used due to fabric size limitations.
[0016] By incorporating soft and elastic rubber pads, the fabric is firmly held in place without leaving indentations or damage, thus protecting its texture and quality. The anti-slip properties of the rubber pads also prevent the fabric from slipping during processing, ensuring the accuracy of jacquard patterns and improving product yield.
[0017] By installing shock-absorbing pads, vibrations generated during the operation of the jacquard machine can be effectively absorbed, reducing the impact of vibrations on the precision components inside the equipment and extending the service life of components such as the robotic arm and jacquard structure. At the same time, the shock-absorbing pads reduce operating noise, improve the working environment, and reduce the transmission of vibrations to the fabric, avoiding problems such as jacquard misalignment and pattern blurring caused by vibration, thus ensuring stable jacquard quality.
[0018] By setting up a controller, the entire process can be automated. Operators only need to input relevant commands into the controller to automatically complete operations such as fabric spreading, spacing adjustment, and jacquard weaving, reducing human error and improving production stability and consistency. In addition, intelligent control facilitates production data monitoring and analysis, helping companies optimize production processes and improve management efficiency. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0024] like Figure 1-3The illustrated jacquard machine for silk fabric includes a base 2, with a worktable 1 connected to the top of the base 2. A robotic arm 6 is connected to the worktable 1. The robotic arm 6 includes seven axes and a forearm, middle arm, and rear arm. One end of one axis is rotatably connected to the worktable 1, and the other end is fixedly connected to the rear arm. The other end of the rear arm is fixedly connected to a second axis. One end of the second axis is rotatably connected to a third axis, and the other end of the third axis is fixedly connected to the middle arm. One end of the middle arm is fixedly connected to a fourth axis, and the fourth axis is rotatably connected to a fifth axis. The other end of the fifth axis is fixedly connected to the forearm. One end of the forearm is fixedly connected to a sixth axis, and the sixth axis is rotatably connected to a seventh axis. The robotic arm 6 controls a jacquard structure 7, allowing for convenient and comprehensive jacquard processing of silk fabric. Unlike other jacquard structures 7, which have limited working areas and require manual manipulation of the silk fabric to achieve the jacquard function, this machine offers advantages such as low applicability and low operating efficiency. The other end of the seven axes of the robotic arm 6 is connected to the jacquard structure 7, and the jacquard machine contains a linear motor. By controlling the input commands to the linear motor, the jacquard needle can be easily controlled to draw different patterns, enabling the jacquard machine to support multiple patterns and meet the diverse needs of different customers. Two sliding rods 11 are symmetrically slidably connected to both ends of the worktable 1. A horizontal plate 10 is connected to the top of each pair of sliding rods 11. Two sliders 5 are symmetrically slidably connected to the two horizontal plates 10. Each slider 5 is connected to a spreading device, which includes a connecting block 8. Each connecting block 8 is connected to a corresponding slider 5. A stepper motor 9 is connected to the outer wall of each connecting block 8. A worm gear 18 is connected to the output end of each stepper motor 9. Each worm gear 18 is rotatably connected to the inner wall of a corresponding connecting block 8. A rotating shaft 16 is rotatably connected to each connecting block 8. Each rotating shaft 16 is connected to a worm wheel 17. Each worm wheel 17 meshes with a corresponding worm gear 18. One end of the shaft 16 extending from the connecting block 8 is connected to a rotating block 15. Each rotating block 15 is connected to an electric telescopic rod 22, and the telescopic end of each electric telescopic rod 22 is connected to a pressing plate 21. Each rotating block 15 has a pressing base plate 19 connected to its bottom, and each pressing plate 21 cooperates with its corresponding pressing base plate 19. The stepper motor 9 is started, causing its output end to drive the worm gear 18 to rotate. Through the meshing of the worm wheel 17 and the worm gear 18, the shaft 16 and rotating blocks 15 rotate, thereby allowing the pressing plates 21 and pressing base plates 19 to rotate. This adjusts the tension of the silk fabric in different directions, making the overall tension of the fabric more uniform, which is beneficial for improving jacquard precision and quality. The electric telescopic rod 22 controls the raising and lowering of the pressing plate 21, realizing the pressing and releasing operation of the silk fabric. The worktable 1 and the horizontal plate 10 are respectively connected to an adjustment device, which is used to adjust the spacing.
[0025] like Figure 2As shown, the adjustment device includes two dual-axis motors 13 connected to the worktable 1. Each dual-axis motor 13 has two sets of output terminals connected to screws 14. The threads of the two screws 14 of each dual-axis motor 13 are arranged in opposite directions. Each screw 14 is rotatably connected to the worktable 1, and the bottom of each sliding rod 11 is movably connected to the corresponding screw 14. The worktable 1 has a groove 12 corresponding to the sliding rod 11, and each sliding rod 11 is slidably connected to its corresponding groove 12. When the dual-axis motor 13 is started, the motor's power is transmitted to the screws 14, and the screws 14 begin to rotate. Because the threads of the two screws 14 are in opposite directions, during the rotation of the screws 14, the two sliding rods 11 movably connected to the screws 14 move synchronously and at the same speed in opposite directions, thereby adjusting the distance between the two horizontal plates 10. The connection between the adjusting device and the horizontal plate 10 is the same as the connection between the adjusting device and the worktable 1, used to adjust the spacing between the sliders 5 on the horizontal plate 10 to accommodate the spreading requirements of silk fabrics of different sizes. When the dual-axis motor 13 on the horizontal plate 10 is started, the rotation of the screw 14 will drive the sliders 5 to slide within the groove 12 of the horizontal plate 10. By controlling parameters such as the forward and reverse rotation and the number of rotations of the dual-axis motor 13, the spacing between the sliders 5 can be precisely adjusted.
[0026] like Figure 3 As shown, rubber pads 20 are connected to the opposite sides of the pressing plate 21 and the pressing base plate 19. The rubber pads 20 can firmly press the fabric and prevent damage to the fabric.
[0027] like Figure 1 As shown, a shock-absorbing pad 3 is connected to the bottom of the base 2. The shock-absorbing pad 3 effectively absorbs the vibrations generated during the operation of the jacquard machine, reducing the impact of vibrations on the precision components inside the equipment. It also reduces operating noise, improves the working environment, and prevents vibrations from being transmitted to the silk fabric, affecting the jacquard quality. The workbench 1 is connected to a controller 4. The robotic arm 6, jacquard structure 7, stepper motor 9, electric telescopic rod 22, and dual-axis motor 13 are electrically connected to the controller 4, realizing automated control of the entire jacquard machine. Operators can input relevant commands through the controller 4 to control the coordinated work of each component, completing the spreading and jacquard operations of the silk fabric, improving production efficiency and product quality, and facilitating production management and monitoring.
[0028] The specific implementation process is as follows:
[0029] First, the silk fabric is placed on the workbench 1. Then, the edges of the fabric are placed on the four pressing base plates 19. The electric telescopic rod 22 is lowered, causing the pressing plate 21 to engage with the pressing base plates 19 to press the edges of the fabric. Next, according to the fabric size, the controller 4 activates the adjustment device, causing the dual-axis motor 13 to drive the screw 14 to rotate, which in turn moves the corresponding sliding rod 11 and slider 5, adjusting the spacing of the spreading device to match the fabric size. Subsequently, as needed, the controller 4 activates the stepper motor 9, which drives the rotating block 15, pressing plate 21, and pressing base plate 19 to rotate via the worm gear 18 and worm wheel 17, adjusting the fabric tension. Then, the robotic arm 6, according to the preset program and instructions, drives the jacquard structure 7 to perform jacquard operations on the silk fabric. The linear motor inside the jacquard structure 7 controls the movement of the jacquard needles according to different patterns to complete the pattern drawing.
