Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing technology, and in particular to a color transfer printing mechanism and a Shu brocade pattern equipment and processing method thereof. Background Technology

[0002] Shu brocade, one of China's four famous brocades, boasts a weaving history of over two thousand years. Its intricate and exquisite patterns, vibrant and rich colors, and cultural and artistic value are all present. Shu brocade color transfer printing combines traditional craftsmanship with modern technology. Using digital inkjet printing or heat transfer printing, high-precision patterns are directly transferred onto the brocade base. Through an intelligent temperature and pressure regulation system, it ensures that dye molecules deeply penetrate the silk threads, preserving the original luster and texture of Shu brocade while achieving complex gradations and micro-carving-level details.

[0003] 1. Current technology often uses the method of laying Shu brocade flat on the transfer table. Because the surface of Shu brocade is relatively slippery, it cannot be effectively restrained during the printing process, which affects the accuracy of the transfer.

[0004] 2. Traditional transfer printing equipment often involves moving the machine body left and right to perform the transfer, or waiting for a new Shu brocade to be replaced before starting work after the transfer is completed. Moving the machine body is relatively more energy-consuming, and replacing the Shu brocade before starting work will take up a lot of time, resulting in low work efficiency.

[0005] 3. In the past, most equipment used rigid printing, which could only press the high points of the fabric flat. For fabrics like Shu brocade with many long floating threads, the low points could not be transferred with color, which could easily cause uneven color transfer. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of existing technology, such as the slippery surface of Shu brocade, which makes it difficult to effectively limit the printing process, affecting the accuracy of the transfer, the energy consumption of moving the transfer machine left and right, the time wasted after replacing the Shu brocade, the low work efficiency, and the fact that rigid pressing can easily cause uneven color transfer. Therefore, this invention proposes a color transfer mechanism, Shu brocade pattern equipment and processing method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A color transfer mechanism, comprising:

[0009] The base has four casters installed at its bottom and a tabletop fixedly connected to its top. A turntable is rotatably connected to the top of the tabletop. A rotating ring is provided at the bottom of the turntable, and an annular groove is provided at the top of the tabletop, with the rotating ring rotating within the annular groove.

[0010] An intermittent rotation component, located within the platform, is used to drive the turntable to rotate intermittently.

[0011] In one possible design, the intermittent rotation assembly includes a rotating shaft rotatably connected within a platform. The rotating shaft extends above the platform and is fixedly connected to and through a turntable. From top to bottom, a mating disc and a grooved wheel are sequentially fitted onto the outer wall of the rotating shaft. A dial is rotatably connected within the platform, and a pin is fixedly connected to the top of the dial. The pin engages with the grooved wheel. A drive motor is fixedly connected within a base. The output shaft of the drive motor extends through the base into the platform and is fixedly connected to the bottom of the dial. The mating disc fits against the end face of the dial. A mounting groove is provided within the platform, and the rotating shaft, mating disc, grooved wheel, and pin are all located within the mounting groove.

[0012] A Shu brocade pattern making device also includes four placement platforms, each with a base fixedly installed at its bottom. Each of the four placement platforms is fixedly connected to the top of a turntable via the base. Multiple short needles are arranged at equal intervals on the top of the limiting plate.

[0013] It also includes a square cover plate, the bottom of which is fixedly connected to an elastic film. The bottom size of the elastic film is slightly larger than the size of the limiting plate and corresponds to the four limiting plates one by one. The elastic film contains silicone oil, which can transmit hydrostatic pressure and make the elastic film adhere to the surface of Shu brocade.

[0014] In one possible design, multiple square cover plates are fixedly mounted with electric heating wires at their bottoms, the electric heating wires being immersed in silicone oil.

[0015] In one possible design, an L-shaped frame is also included, which is fixedly connected to the top of the base. An electric push rod is fixedly connected inside the L-shaped frame. The output shaft of the electric push rod extends to the bottom of the L-shaped frame. A connecting plate is fixedly connected to the bottom end of the output shaft of the electric push rod. The connecting plate is fixedly connected to the top of the square cover plate. A PLC controller is installed at one end of the L-shaped frame. The PLC controller is electrically connected to the drive motor, the electric heating wire, and the electric push rod.

[0016] In one possible design, the top of the connecting plate is fixedly connected to multiple limiting rods, and the L-shaped frame is provided with four limiting slots, with the four limiting rods corresponding to the four limiting slots in a sliding fit.

[0017] In one possible design, multiple short needles are arranged at an angle with the same tilt direction and angle. The top of each short needle is provided with a ball head, which is designed to avoid damaging the Shu brocade fibers. The oblique arrangement enhances the binding and firmness of the Shu brocade.

[0018] A method for processing Shu brocade pattern-making equipment includes the following steps:

[0019] S1. Lay the Shu brocade flat on the limiting board on the top of the placement table. Insert the short needles at the top of the limiting board into the gaps between the yarns on the back of the Shu brocade. The spherical top avoids puncturing the fibers, thus effectively limiting the Shu brocade.

[0020] S2. Drive the drive motor, whose output shaft drives the dial to rotate. The dial drives the grooved wheel to rotate through the pin. The grooved wheel drives the rotating shaft and the mating plate to rotate. The mating plate and the dial are positioned and matched, so that the rotating shaft drives the turntable to rotate intermittently, thereby driving the limiting plate and Shu brocade to move step by step.

[0021] S3. Drive the electric heating wire to heat the silicone oil in the elastic film to the preset transfer temperature;

[0022] S4. When the limiting plate carrying Shu brocade rotates to the underside of the elastic film, the electric push rod is driven, and its output shaft extends to drive the connecting plate and the square cover plate to move down, so that the elastic film fits the surface of Shu brocade. The elastic film deforms under the action of the hydrostatic pressure of the silicone oil fluid, ensuring that the transfer pressure is evenly applied to each yarn. After the transfer is completed, the electric push rod retracts and resets, and the turntable rotates to the next station.

[0023] In this application, Shu brocade is placed on a limiting plate on top of a placement platform. Short needles are placed diagonally on the top of the limiting plate and embedded into the gaps between the yarns on the back of the fabric without piercing the fibers, thus effectively limiting the fabric. A PLC controller then powers a drive motor, whose output shaft drives a dial to rotate. The dial drives a pin to rotate, which in turn drives a grooved wheel to rotate. The grooved wheel drives a mating disc on top to rotate. The mating disc and dial together cause a rotating shaft to rotate, which in turn drives a turntable to rotate. The rotation of the turntable, driven by the interaction of the pin and the grooved wheel, causes the turntable to rotate intermittently. This rotation of the turntable causes the limiting plate on top to rotate, and simultaneously powers an electric heating wire installed under a square cover plate. The silicone oil inside the elastic film is heated. When the limiting plate containing the Shu brocade rotates to below the elastic film, the electric push rod is energized. The output shaft of the electric push rod extends, causing the elastic film to adhere to the surface of the Shu brocade. At the same time, the elastic film deforms under the hydrostatic pressure of the silicone oil, ensuring that the transfer pressure is uniform on each yarn. During the extension and pressing process of the electric push rod output shaft, multiple limiting rods slide within the L-shaped frame to limit the transfer. The turntable drives the placement table to rotate intermittently. When the placement table is below the L-shaped frame, the electric push rod performs the printing. After the Shu brocade is printed, it can be removed directly from the surface of the limiting plate after being rotated out from below the L-shaped frame, and a new Shu brocade to be printed can be placed on top.

[0024] Beneficial effects: In this invention, the color transfer mechanism and Shu brocade pattern equipment and processing method, by using short needles placed obliquely at the top of the limiting plate to embed into the gaps of the yarns on the back of the Shu brocade, can effectively limit the fabric without piercing the fibers, ensuring the stability of the Shu brocade position during transfer; at the same time, the pin and the grooved wheel work together to drive the turntable to rotate intermittently, so that the transfer process is carried out in an orderly manner, effectively improving the accuracy and stability of the transfer.

[0025] In this invention, the color transfer mechanism and Shu brocade pattern equipment and processing method utilize an electric heating wire to heat the silicone oil inside the elastic film, and an electric push rod drives the elastic film to adhere to the surface of the Shu brocade. The elastic film is deformed by the hydrostatic pressure of the silicone oil fluid, ensuring that the transfer pressure is evenly applied to each yarn, thereby improving the color transfer quality and making the Shu brocade pattern more uniform and vibrant.

[0026] In this invention, multiple aspects of the design are optimized, from fabric fixing and rotation control to transfer pressure adjustment, effectively improving the accuracy and stability of transfer, ensuring transfer quality, and providing reliable support for Shu brocade pattern processing.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1 A color transfer mechanism and a Shu brocade pattern equipment are used in the textile printing and dyeing field. The color transfer mechanism is supported by a base 1 and moves by four universal wheels 22 at the bottom of the base 1. A platform 3 is fixedly installed on the top of the base 1. The platform 3 and the turntable 4 are rotated and engaged by a rotating ring 24 within a limiting ring 25 to ensure the stable rotation of the turntable 4.

[0037] Reference Figure 2 and Figure 3 An intermittent rotating assembly is installed inside the mounting groove 26 of the platform 3. A rotating shaft 12 is rotatably connected within the mounting groove 26, with its upper end extending above the platform 3 and fixedly passing through the center of the turntable 4. From top to bottom, a mating disc 9 and a grooved wheel 8 are sequentially fixedly fitted onto the outer wall of the rotating shaft 12. A dial 10 is rotatably connected to the corresponding position within the mounting groove 26. A pin 11 is fixedly connected to the top of the dial 10, engaging with the groove of the grooved wheel 8. The bottom of the dial 10 engages with the side of the mating disc 9. A drive motor 7 is fixedly installed inside the base 1, with its output shaft extending through the base 1 into the platform 3 and fixedly connected to the bottom of the dial 10. When the drive motor 7 starts, the output shaft drives the dial 10 to rotate, causing the pin 11 to rotate and push the grooved wheel 8 to rotate intermittently. Through the synergistic effect of the mating disc 9 and the dial 10, the rotating shaft 12 achieves intermittent rotation, thereby driving the turntable 4 to rotate synchronously.

[0038] Reference Figure 2 and Figure 4 Four placement platforms 5, each mounted on a base 21, are evenly fixed to the top of the turntable 4. A limiting plate 6 is fixedly connected to the top of each placement platform 5. Multiple short needles 13 are evenly spaced on the top of the limiting plate 6. The short needles 13 are arranged at an angle, with the angle consistent with the direction of inclination, and their tips are designed with ball heads 20. This structure allows the short needles 13 to embed into the gaps in the yarn on the back of the Shu brocade, effectively limiting the fabric without piercing the fibers.

[0039] Reference Figure 2 and Figure 5An L-shaped frame 2 is installed on top of the equipment, with its horizontal section fixed to the top of the base 1 and its vertical section extending downwards. An electric push rod 14 is fixedly installed inside the L-shaped frame 2, with its output shaft extending vertically downwards. A connecting plate 18 is fixedly connected to the bottom end of the output shaft of the electric push rod 14, and a square cover plate 15 is fixedly connected to the bottom of the connecting plate 18. An elastic diaphragm 17, made of silicone, is fixedly installed at the bottom of the square cover plate 15. The edge of the elastic diaphragm 17 is detachably fixed to the bottom of the square cover plate 15 by bolts through an annular sealing ring. A fluororubber sealing gasket is sandwiched between the sealing ring and the elastic diaphragm 17, forming a sealed chamber. The bottom dimension of the chamber is slightly larger than that of the limiting plate 6. Silicone oil is filled inside the elastic diaphragm 17, which serves as a pressure transmission medium to ensure uniform pressure distribution. Multiple limiting rods 16 are fixedly connected to the top of the connecting plate 18. The limiting rods 16 are slidably connected within the pre-set limiting grooves 23 in the vertical section of the L-shaped frame 2, serving as guides and limiters.

[0040] Reference Figure 6 An electric heating wire 19 is fixedly installed at the bottom of the square cover plate 15. The electric heating wire 19 is made of nickel-chromium alloy, which has high temperature resistance and oxidation resistance. Its layout is completely immersed in silicone oil. The heating temperature of the electric heating wire 19 can be adjusted by the PLC controller 27 to keep the silicone oil at a suitable transfer temperature.

[0041] refer to Figures 1 to 7 A processing method for a Shu brocade patterning device: Step S1: The Shu brocade to be processed is laid flat on the limiting plate 6 at the top of the placement table 5. Short needles 13 placed at an angle are embedded into the gaps between the yarns on the back of the fabric. The spherical needle tip design avoids piercing the fibers, thus achieving a stable locking of the fabric.

[0042] Step S2: Start the drive motor 7. Its output shaft drives the dial 10 to rotate, and the pin 11 rotates accordingly, pushing the grooved wheel 8 to move intermittently. The grooved wheel 8 drives the mating disc 9 to rotate synchronously through the rotating shaft 12. The synergistic effect of the mating disc 9 and the dial 10 ensures that the rotating shaft 12 achieves precise intermittent rotation. The rotating shaft 12 ultimately drives the turntable 4 to rotate, causing the four limiting plates 6 to rotate sequentially to the processing station.

[0043] Step S3: The PLC controller 27 powers the heating wire 19 via a temperature control switch. The nickel-chromium alloy heating wire 19 rapidly heats up and transfers heat to the silicone oil, bringing it to the preset transfer temperature. A temperature sensor monitors the silicone oil temperature in real time and maintains a stable temperature through the control system.

[0044] Step S4: When the limiting plate 6 carrying the Shu brocade rotates to directly below the elastic film 17, the electric push rod 14 is activated. Its output shaft extends, pushing the connecting plate 18 downwards, causing the square cover plate 15 and the elastic film 17 to descend synchronously. After the silicone elastic film 17 contacts the surface of the Shu brocade, it undergoes uniform deformation under the hydrostatic pressure of the silicone oil, ensuring that the transfer pressure is precisely applied to each yarn. The limiting rod 16 slides synchronously within the groove of the L-shaped frame 2, ensuring a smooth and unbiased downward pressing process. After the transfer is completed, the electric push rod 14 retracts, causing the elastic film 17 to rise again, and the turntable 4 continues to rotate to the next station. The operator can quickly remove the processed Shu brocade and replace it with a new fabric, achieving continuous production.

[0045] The PLC controller presets the transfer temperature, the downward stroke and pressure of the electric push rod 14, the transfer time, and the intermittent rotation angle of the turntable 4. The PLC controller 27 forms a closed-loop control with the drive motor 7, the electric push rod 14, and the electric heating wire 19.

[0046] During long-term use, this device requires regular maintenance by applying high-temperature grease to the mating surfaces of the rotating shaft 12, the grooved wheel 8, the dial 10, and the sliding contact between the limiting rod 16 and the L-shaped frame 2. At the same time, the integrity of the elastic diaphragm 17 and the sealing performance of the sealing ring should be checked. If silicone oil leakage is found, silicone oil should be added in time and the sealing gasket should be replaced to ensure stable operation of the equipment.

[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 7, electric push rod 14 and electric heating wire 19 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0048] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
