Abstract
Description
Technical Field
[0001] This utility model relates to the field of embroidery machine technology, and in particular to a color-changing device for a digital embroidery machine with a rotating color disc structure. Background Technology
[0002] The color-changing device of digital embroidery machines is widely used in embroidery processing in industries such as clothing, leather, and textiles. Through the color-changing device, the embroidery machine can achieve multi-color embroidery, meeting the market demand for diversified and personalized embroidery products.
[0003] The existing literature on color changing devices for embroidery machines (CN207525467U) can be referenced. The reference describes how color changing rollers slide along the color changing groove, which reduces the friction between the color changing rollers and the color changing wheel, thus improving the service life of the color changing wheel. The color changing wheel is located inside the color changing box, while the color changing guide plate is located outside the box. The color changing guide plate is not limited by the volume of the box, and multiple color changing rollers can be installed on the color changing guide plate as needed.
[0004] In existing technologies, color-changing devices are generally driven by a drive mechanism (such as a motor, bevel gear set, etc.) that drives the color-changing wheel or needle bar frame to move according to control commands. Multiple rotary shuttles are usually arranged side by side on the color-changing wheel, each shuttle carrying a different color of embroidery thread. By rotating the color-changing wheel or moving the needle bar frame, the needle bar is switched to the corresponding color position to achieve color changing. The aforementioned literature uses a bevel gear set to drive the color-changing wheel to rotate, and the rotation of the color-changing wheel drives the needle bar frame to move linearly to achieve color changing. Although this design is simple to operate, it requires manual observation of the position of the needle bar frame to determine whether the color change is successful. Furthermore, since the aforementioned literature drives the needle bar frame to move through the spiral color-changing groove on the surface of the color-changing wheel, it is easily affected by external vibrations after the color change is completed, which can cause it to shift and thus affect the stability of the embroidery process. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a color-changing device for a digital embroidery machine with a rotating color wheel structure. During each color change, the corresponding infrared receiver receives an infrared signal and simultaneously activates the corresponding color indicator light. The lit color indicator light indicates that the specified color has been switched, allowing for quick determination of whether the color change is complete. Furthermore, after the color change is finished, a locking component fixes the position, improving stability during the embroidery process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A color-changing device for a digital embroidery machine with a rotating color wheel structure includes: a mounting plate; a stepper motor fixed to the front end of the mounting plate; a rotating rod connected to the output end of the stepper motor; a rotating color wheel fixedly connected to the outside of the rotating rod; multiple infrared receivers embedded and fixed inside the rotating color wheel; an equal number of color indicator lights evenly distributed on the surface of the rotating color wheel; an infrared emitter provided at the front end of the mounting plate, ensuring that the uppermost infrared receiver is always aligned with the infrared emitter; and two slide rails provided at the front end of the mounting plate via a connecting rod, each slide rail containing a slider that can only slide laterally, and each slider containing a locking component to fix the position of the slider.
[0008] The present invention is further configured such that the infrared receivers are all arranged in a ring at equal intervals, and each infrared receiver is connected to a corresponding color indicator light signal.
[0009] The present invention is further configured such that an angle sensor is provided at the end of the rotating rod, and the angle sensor is connected to an external control terminal for signal transmission.
[0010] The present invention is further configured such that a gear is integrally connected to the outer side of the rotating rod, and a rack is fixed on the surface of the upper slider, with the rack meshing below the gear.
[0011] The present invention is further configured such that an L-shaped fixing frame is fixedly connected to the upper end of each slider, and the other end of each fixing frame is connected to the back of the embroidery frame.
[0012] The present invention is further configured such that a limiting plate is provided at the upper end of each slide rail, and a slide rail is provided on the through surface of the limiting plate, and the fixing frame is positioned in the slide rail and moves linearly.
[0013] The present invention is further configured as a locking component comprising: an electric cylinder, which is fixedly installed inside the slider; a limiting block, which is connected to the telescopic end of the electric cylinder, and a plurality of limiting slots corresponding to the number of colors are provided on the inner side of the slide rail, wherein the limiting block is inserted into the corresponding limiting slot to fix the position of the slider.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The color-changing device of this digital embroidery machine uses a stepper motor to drive a gear to rotate at a fixed angle, causing the meshing rack to move a fixed distance. This, in turn, causes the embroidery frame to move a fixed distance to complete the color change. During the color change process, the color disc rotates synchronously. The infrared receiver located at the top inside the color disc receives an infrared signal and simultaneously sends a signal to the color indicator light. The color indicator light lights up after receiving the signal, indicating that the color has been switched to the specified color. This allows the operator to quickly determine whether the switch is complete without having to observe the position of the embroidery frame.
[0016] 2. After the color change is completed, the locking component inside the slider of the digital embroidery machine operates, so that the limit block fits into the corresponding limit slot inside the slide rail, fixing the position of the slider and thus simultaneously fixing the position of the embroidery frame, making it less susceptible to displacement due to external vibration and improving the stability during the embroidery process.

[0028] Reference Figure 1-6 A color-changing device for a digital embroidery machine with a rotating color disc structure includes: a mounting plate 1, which is the main load-bearing component of the device. A stepper motor 6 is fixed on the surface of the mounting plate 1, and two slide rails 4 are fixed on the surface of the mounting plate 1 through a connecting rod 11.
[0029] Specifically, such as Figure 3 As shown, a rotating rod 20 is fixed to the output end of the stepper motor 6, a rotating color disk 2 is fixedly connected to the outside of the rotating rod 20, and an angle sensor 10 is provided at the end of the rotating rod 20.
[0030] Furthermore, multiple infrared receivers 7 are evenly distributed in a ring inside the rotating color wheel 2, and the same number of color indicator lights 8 are distributed in a ring on the surface of the rotating color wheel 2. This number corresponds to the number of colors in the embroidery frame 5, and the color of the color indicator light 8 represents the corresponding color of the embroidery frame 5.
[0031] Furthermore, an infrared transmitter 3 is provided at the front end of the mounting plate 1, and the infrared transmitter 3 is located above the stepper motor 6.
[0032] It should be noted that the operation of the stepper motor 6 drives the rotating rod 20 to rotate at a fixed angle, so that the uppermost infrared receiver 7 can always be aligned with the infrared transmitter 3. The color indicator light 8 is an intelligent signal light with a built-in signal receiving module and signal processing module. After the infrared receiver 7 receives the infrared signal, it sends a signal to the corresponding color indicator light 8. After the color indicator light 8 finishes processing the signal, it lights up synchronously.
[0033] In this embodiment, the color change is activated by an external control terminal. During the rotation of the rotating rod 20, the rotation angle is detected by the angle sensor 10 at the end, and the detection signal is then transmitted to the external control terminal.
[0034] Specifically, such as Figure 4 As shown, sliders 13 are slidably installed inside the slide rail 4, and a rack 12 is fixed on the surface of the upper slider 13.
[0035] At the same time, such as Figure 3 As shown, a gear 9 is fixed to the outside of the rotating rod 20, which is engaged with... Figure 1-2 As shown, the rack 12 is engaged below the gear 9.
[0036] And, as Figure 5-6 As shown, an L-shaped fixing bracket 14 is fixed above the slider 13, and a limiting plate 17 is provided above the slide rail 4. A slide rail 18 is provided through the surface of the limiting plate 17. The two fixing brackets 14 are fitted in the slide rail 18 and move linearly. The other end of the fixing brackets 14 is fixed to the back of the embroidery frame 5.
[0037] In this embodiment, the slider 13 can only move laterally in a straight line inside the slide rail 4 by the limiting plate 17, so that the rotation of the gear 9 at a fixed angle drives the rack 12 to move a fixed distance, thereby completing the equidistant adjustment of the position of the embroidery frame 5 to achieve color change.
[0038] For details, please refer to Figure 5-6 As shown, a locking component is provided inside the slider 13, and multiple limit slots 19 corresponding to the number of colors are opened on the inner side of the slide rail 4.
[0039] The locking assembly includes an electric cylinder 15 and a limiting block 16. The electric cylinder 15 is installed inside the slider 13, and the limiting block 16 is connected to the telescopic end of the electric cylinder 15. After the color change is completed, the electric cylinder 15 runs and drives the limiting block 16 to fit into the corresponding limiting slot 19, thereby fixing the position of the slider 13 and locking the position of the embroidery frame 5, thus improving the stability during the embroidery process.
[0040] Correspondingly, when changing colors again, the control unit will first activate the locking component to release the position lock of the embroidery frame 5.
[0041] Working principle: The stepper motor 6 drives the gear 9 to rotate at a fixed angle, causing the meshing rack 12 to move a fixed distance, which in turn causes the embroidery frame 5 to move a fixed distance to complete the color change. During the color change, the rotating color disk 2 rotates synchronously. The infrared receiver 7 located at the top inside the rotating color disk 2 receives the infrared signal and sends a signal to the color indicator 8. The color indicator 8 lights up after receiving the signal, indicating that the color has been switched to the specified color. This allows the operator to quickly determine whether the color change is complete without observing the position of the embroidery frame 5. After the color change is completed, the locking component inside the slider 13 operates, causing the limit block 16 to fit into the corresponding limit slot 19 inside the slide rail 4, fixing the position of the slider 13. This, in turn, simultaneously fixes the position of the embroidery frame 5, making it less susceptible to displacement due to external vibration and improving the stability during the embroidery process.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
