Abstract
Description
Technical Field
[0001] This application relates to the field of ribbon embroidery technology, specifically to a ribbon embroidery device. Background Technology
[0002] Ribbon embroidery devices are used for embroidering ribbons and / or ropes. During ribbon embroidery, a drive motor rotates the ribbon thread wheel frame, feeding the rope or ribbon wound on the frame to the area to be embroidered. The needle inserts into the fabric, and the thread secures the rope or ribbon to the fabric. During the embroidery process, the presser foot and thread wheel frame work in conjunction with the needle bar to perform forward and reverse rotation, and up and down reciprocating motions as needed. However, given the existing structure of ribbon embroidery devices, the following problems still exist:
[0003] ① In the existing ribbon embroidery device, the thread take-up lever is always connected to the drive device when changing the face thread. When the machine is started unexpectedly, it will directly drive the thread take-up lever to move, which will pose a safety hazard during the face thread changing process.
[0004] ② In most ribbon embroidery devices, the ribbon is pulled along with the fabric during use. The pulling force directly causes the ribbon to be continuously and passively conveyed from the feed wheel, resulting in a continuous embroidery ribbon. The required pulling force depends on the number of ribbons on the ribbon reel. When there are many ribbons on the reel, the required pulling force is large, which will cause the ribbon to be too tense and deformed. After sewing, the ribbon cannot be tightened because the top thread is fixed. As the number of ribbons on the reel decreases, the required pulling force decreases, the ribbon deformation decreases, which will result in the embroidered bags having different shapes and poor aesthetics.
[0005] ③During the embroidery process, the presser foot and thread wheel frame work together with the needle bar to complete forward and reverse rotation, up and down reciprocating motion as needed. When the presser foot and thread wheel frame rotate synchronously using the same drive mechanism, the large weight of the thread wheel frame and its large inertia will result in low control accuracy of the presser foot and poor flexibility in forward and reverse movement. Utility Model Content
[0006] In view of this, this application provides a ribbon embroidery device to solve the technical problems of certain safety hazards when changing the thread, inconsistent tension of the ribbon during the embroidery process, and poor flexibility of the presser foot.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A ribbon embroidery device includes a frame, a thread wheel frame, a presser foot assembly, an embroidery needle assembly, and a thread take-up assembly mounted on the frame. The device further includes a clutch control mechanism and a thread take-up control mechanism. The thread take-up assembly includes a thread take-up shaft mounted on the frame and a thread take-up frame slidably mounted on the thread take-up shaft. The thread take-up control mechanism is used to drive the thread take-up frame to swing. The clutch control mechanism controls the disengagement and engagement states of the thread take-up frame and the thread take-up control mechanism by driving the thread take-up frame to move.
[0009] Furthermore, the line-picking frame has forks, and the line-picking control mechanism has a plug-in shaft that works in conjunction with the forks. The disengagement and engagement states are controlled by controlling the relative position of the forks and the plug-in shaft.
[0010] Furthermore, the clutch control mechanism includes a swing link with a pin connected to it. The take-up shaft is also equipped with a first limit sleeve and a top pressure spring located on both sides of the take-up frame. When the pin swings, it acts on the first limit sleeve to drive the take-up frame to slide.
[0011] Furthermore, the clutch control mechanism also includes a connecting shaft rotatably mounted on the frame and a pull rod slidably mounted on the frame. The two ends of the connecting shaft are respectively connected to the swing link and the transition link. The optical shaft mounted on the transition link cooperates with the second limit sleeve mounted on the pull rod.
[0012] Furthermore, the line-flipping control mechanism also includes a hinged swing arm, with a plug-in shaft mounted on one end of the swing arm, and the other end of the swing arm cooperating with the eccentric ring groove of the line-flipping control mechanism.
[0013] Furthermore, the thread-taking control mechanism also includes a lifting block and an eccentric wheel with a lifting and sliding configuration. The eccentric wheel is connected to the lifting block via a linkage assembly to control the lifting block's movement. The lifting block is connected to the embroidery needle assembly.
[0014] Furthermore, the rotating drum of the reel frame is hinged to the machine frame, and the rotating drum is connected to the first rotation drive mechanism. The outer ring of the rotating drum is provided with a liftable wire lifting ring, and the swing wire guide frame installed on the reel frame swings up and down with the lifting of the wire lifting ring.
[0015] Furthermore, the presser foot rod of the presser foot assembly is located inside the rotating cylinder, and the presser foot rod can be raised, lowered, and rotated; the needle bar of the embroidery needle assembly is located inside the presser foot rod, and the needle bar is connected to the lifting block of the thread take-up control mechanism.
[0016] Furthermore, the outer circumferential surface of the presser foot bar has axially distributed grooves, and the driven wheel, which is slidably fitted onto the presser foot bar, is provided with a linkage limit block that cooperates with the grooves.
[0017] Furthermore, the frame has a locking notch, the take-up end of the take-up frame is located on the outside of the frame, and the take-up frame after being separated from the take-up control mechanism will slide into the locking notch and remain in an upward state.
[0018] As can be seen from the above technical solution, the advantages of this utility model are:
[0019] 1. The technical solution proposed in this application innovatively employs a clutch control mechanism to regulate the engagement and disengagement states between the thread take-up frame and the thread take-up control mechanism. During thread changing operations, the clutch control mechanism ensures that the thread take-up frame and the thread take-up control mechanism are disengaged. This design significantly enhances the safety of the thread changing process, effectively preventing the safety hazard of accidental activation of the thread take-up frame and providing strong support for the stable operation of the entire embroidery equipment.
[0020] 2. In this application, the lever of the clutch control mechanism extends to the outside of the frame, allowing the operator to adjust the position of the take-up frame simply by manipulating the lever from outside the frame. This design makes adjusting the position of the take-up frame extremely convenient, eliminating the need for complex operating procedures or deep adjustments within the equipment. Simultaneously, the take-up hole of the take-up frame is strategically positioned on the outside of the frame, greatly simplifying the wire-changing operation. Operators can perform wire-changing tasks intuitively and conveniently, without needing to spend extra time and effort finding or adjusting the position of the take-up hole, significantly improving work efficiency.
[0021] 3. This application utilizes the lifting and lowering motion of the thread guide ring to control the swinging motion of the oscillating thread guide frame. During the embroidery process, the oscillating thread guide frame repeatedly tensions and relaxes the ribbon being used. This dynamic tension adjustment method ensures that the ribbon maintains a stable and consistent tension throughout the entire embroidery process. Stable tension is crucial for embroidery quality, ensuring that the embroidered ribbon has a uniform shape, achieving ideal embroidery results in terms of line thickness, density, and pattern outline. Furthermore, this design avoids the problems caused by the frequent lifting and lowering of the thread wheel frame in traditional methods. Frequent lifting and lowering of the thread wheel frame not only generates significant operational vibration, affecting the stability and lifespan of the equipment, but also places excessive demands on the load-bearing capacity of the lifting device, increasing operating costs and maintenance difficulty. The technical solution of this application effectively reduces operational vibration and lowers the load-bearing capacity requirements of the lifting device, providing strong support for long-term stable operation and cost control of the equipment.
[0022] 4. The presser foot assembly and the thread wheel frame in this application adopt an independent operating mode. This independent operation design has significant advantages, effectively avoiding the adverse effects of the inertia and weight generated by the thread wheel frame during movement on the position control accuracy and adjustment flexibility of the presser foot assembly. In embroidery equipment, the position control accuracy of the presser foot assembly directly affects the accuracy and quality of the embroidery, while the adjustment flexibility affects the equipment's adaptability to different embroidery needs. By enabling the presser foot assembly and the thread wheel frame to operate independently, it is ensured that the presser foot assembly can accurately achieve position control and flexibly adjust without interference from the thread wheel frame, thereby improving the performance and embroidery quality of the entire embroidery equipment.

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.
[0035] refer to Figures 1 to 9 ,like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this embodiment provides a ribbon embroidery device, including a frame 1, a thread reel frame 2 mounted on the frame 1, a presser foot assembly, an embroidery needle assembly, a thread take-up assembly 8, a clutch control mechanism 50, and a thread take-up control mechanism 80. The thread reel frame 2 provides embroidery ribbon or cord for embroidery work; the presser foot 6 of the presser foot assembly repeatedly rises and falls, pressing the embroidery ribbon or cord firmly against the embroidery fabric for reliable embroidery when it descends, and lifting and relaxing the embroidery ribbon or cord when it rises, allowing the embroidery fabric to move smoothly forward, preparing for subsequent continuous embroidery; the embroidery needle assembly is used to embroider the top thread onto the embroidery fabric, while simultaneously fixing the embroidery ribbon or cord; the thread take-up assembly 8 includes components mounted on the frame 1. The embroidery equipment includes a thread take-up shaft 82 and a thread take-up frame 81 slidably mounted on the thread take-up shaft 82. The thread take-up control mechanism 80 is used to drive the thread take-up frame 81 to swing up and down to relax or tighten the thread, forming a stable thread loop and keeping the thread at a certain tension during the embroidery process, resulting in a neat pattern. The clutch control mechanism 50 controls the engagement and disengagement of the thread take-up frame 81 and the thread take-up control mechanism 80 by driving the thread take-up frame 81 to move along the thread take-up shaft 82. The design of the clutch control mechanism 50 greatly improves the safety of the thread changing process, effectively avoids the safety hazards caused by the accidental start of the thread take-up frame 81, and provides a strong guarantee for the stable operation of the entire embroidery equipment.
[0036] In the ribbon embroidery device, in order to keep the thread take-up frame 81 in an upward state after being separated from the thread take-up control mechanism 80, a locking notch 111 is provided on the sealing plate 11 of the frame 1. The thread take-up end of the thread take-up frame 81 passes through the clearance hole preset on the sealing plate 11 and extends out, so that the thread take-up end of the thread take-up frame 81 is located on the outside of the frame 1. The operator can intuitively and conveniently change the thread without having to spend extra time and effort to find or adjust the position of the thread take-up hole, which significantly improves work efficiency. After being separated from the thread take-up control mechanism 80, the thread take-up frame 81 will slide into the locking notch 111 to be limited and kept in an upward state. When changing the color of the top thread, the top thread needs to pass through the needle 7 and a certain length of thread end will be reserved. After changing the color of the top thread, since the thread take-up frame 81 is always kept in an upward state, the short thread end reserved on the needle 7 will not fall off due to the lifting of the thread take-up frame 81, thus effectively avoiding the problem of embroidery interruption caused by the thread end falling off, and ensuring the continuity and stability of the embroidery work.
[0037] In this application, the thread wheel frame 2 has an upwardly extending drum 21, with the thread wheel located below the drum 21. The drum 21 is hinged to the frame 1 via bearings and is connected to the first rotation drive mechanism 5. The presser foot assembly also includes a presser foot rod 9 connected to the presser foot 6. The presser foot rod 9 is located inside the drum 21 and can be raised, lowered, and rotated. The presser foot 6 has a tape passage. When the presser foot 6 rotates, it will drive the tape or embroidery cord to rotate according to a certain pattern. The presser foot 6 and the thread wheel frame 2 operate independently of each other, and the control precision and flexibility of the presser foot 6 are higher. The embroidery needle assembly includes a needle bar 30 located inside the presser foot rod 9. A needle head 7 is installed below the needle bar 30. The needle bar 30 can be raised and lowered, and the raising and lowering of the needle bar 30 drives the raising and lowering of the needle head 7. The rotating drum 21, presser foot rod 9 and needle bar 30 are installed in sequence to make the structure compact. The needle bar 30 is hollow and has a thread inlet and outlet on the side for the thread to pass through, so that the thread is hidden inside the needle bar 30 and the thread wheel frame 2 and presser foot assembly are prevented from tangling and knotting when they rotate.
[0038] Specifically, the first rotation drive mechanism 5 can be a synchronous belt drive structure, a gear pair structure, or a chain drive mechanism that cooperates with the motor; the upper end of the presser foot rod 9 is higher than the rotating drum 21, the upper end of the presser foot rod 9 is higher than the presser foot rod 9, the presser foot rod 9 is connected to the corresponding lifting drive mechanism 60, the outer circumferential surface of the presser foot rod 9 has axially distributed grooves, the driven wheel of the second rotation drive mechanism 20, which is relatively slidably mounted on the presser foot rod 9, is provided with a linkage limiting block 10 that cooperates with the grooves, when the second rotation drive mechanism 20 rotates, it can drive the linkage limiting block 10 to rotate, thereby driving the presser foot rod 9 to rotate, when the presser foot rod 9 is raised or lowered, the linkage limiting block 10 slides along the grooves, wherein the second rotation drive mechanism 20 is preferably a gear pair structure, the lifting drive mechanism 60 includes a synchronous belt mechanism and a drive fork connected to the synchronous belt, the presser foot rod 9 is provided with a fixed drive ring, the drive fork cooperates with the drive ring, and will not affect the rotation of the presser foot rod 9, the lifting and lowering of the drive fork drives the drive ring to rise or fall, thereby driving the presser foot rod 9 and the presser foot 6 to rise or fall.
[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the outer ring of the rotating drum 21 is equipped with a liftable thread-lifting ring 4, making the structure compact. The swing thread guide 3, hinged to the thread wheel frame 2, swings up and down with the lifting of the thread-lifting ring 4 to repeatedly tighten and loosen the embroidery ribbon or cord. The swing thread guide 3 has a magnetic sleeve for the ribbon or cord to pass through. When the swing thread guide 3 swings, it drives the magnetic sleeve to swing. When the magnetic sleeve rises, it tightens the ribbon. When the ribbon is tightened, it drives the thread wheel to rotate and release the ribbon. When the magnetic sleeve presses down, it relaxes the ribbon, and the embroidery ribbon returns to the tension required for embroidery. This dynamic tension adjustment method can keep the ribbon in a stable and consistent tension throughout the entire embroidery process, ensuring that the embroidered ribbon has a uniform shape. Whether it is the thickness and density of the lines or the outline of the pattern, the ideal embroidery effect can be achieved. In addition, this design avoids the problem of excessive deformation of the ribbon caused by dragging force in the traditional method, which affects the appearance of the pattern, and also avoids the problems caused by the frequent lifting and lowering of the thread wheel frame. Frequent lifting and lowering of the reel frame not only generates significant operational vibration, affecting equipment stability and lifespan, but also places excessive demands on the load-bearing capacity of the lifting device, increasing operating costs and maintenance difficulty. The technical solution presented in this application effectively reduces operational vibration and lowers the load-bearing capacity requirements of the lifting device, providing strong support for long-term stable operation and cost control.
[0040] Specifically, a lifting rod 40 is fixedly connected to the lifting ring 4, and the lifting rod 40 is connected to the corresponding lifting drive mechanism 60. The drive fork of the lifting drive mechanism 60 is engaged or fixedly connected to the drive ring provided on the lifting rod 40.
[0041] like Figure 7 and Figure 8 As shown, the thread take-up control mechanism 80 includes an eccentric wheel 801 and a lifting block 805 that is slidably mounted on a guide rod. The eccentric wheel 801 is connected to the lifting block 805 via a connecting rod assembly to control the lifting of the lifting block 805. The lifting block 805 is connected to the needle bar 30 to control the lifting of the needle tip 7.
[0042] Specifically, the line-picking control mechanism 80 also includes an eccentric shaft connected to a corresponding motor. An eccentric wheel 801 is rotatably mounted on the eccentric shaft. The linkage assembly includes a swing arm 802, a first connecting rod 803, and a second connecting rod 804. The first end of the swing arm 802 is hinged to the frame 1. The second end of the swing arm 802 is coaxially hinged to the extension arm of the eccentric wheel 801 and the first end of the first connecting rod 803. The second end of the first connecting rod 803 is hinged to the first end of the second connecting rod 804. The second section of the second connecting rod 804 is hinged to the lifting block 805. The lifting block 805 has a limiting groove for fixing... The driven block 302 installed on the needle bar 30 cooperates with the limiting groove. The eccentric wheel 801 will move up and down with the rotation of the eccentric shaft, thereby driving the swing arm 802 to swing. The cooperation of the first link 803 and the second link 804 can raise the position of the lifting block 805 and misalign it with the presser foot rod 9, so that the driving of the needle bar 30 is reliable and stable. In order to prevent the needle bar 30 from rotating automatically, the limiting frame 301 fixed on the needle bar 30 is slidably sleeved on the lifting rod 40 to prevent the needle bar 30 from rotating and causing the driven block 302 to separate from the lifting block 805, which would affect the reliability of the lifting control of the needle bar 30.
[0043] In this application, in order to enable the needle bar 30 to be quickly lifted and reset, a reset spring 70 is also sleeved on the needle bar 30, which is limited between the frame 1 and the upper limit ring of the needle bar 30.
[0044] In this application, the line-carrying control mechanism 80 also includes a swinging crank arm 807 hinged to the frame 1 at the inflection point and a turntable 806 coaxial with and rotating synchronously with the eccentric shaft. Each end of the swinging crank arm 807 is provided with a plug-in shaft 8071. The turntable 806 has an eccentric ring groove 8061. The plug-in shaft 8071 installed at one end of the swinging crank arm 807 is used to drive the line-carrying frame 81 to swing. The plug-in shaft 8071 located at the other end of the swinging crank arm 807 slides along the eccentric ring groove 8061. When the turntable 806 rotates, it drives the swinging crank arm 807 to swing, thereby driving the line-carrying frame 81 to swing. With this structure, the oscillation drive of the line-carrying frame 81 can be completed by the turntable 806 working in one direction.
[0045] To achieve the engagement and disengagement of the thread-carrying frame 81 and the thread-carrying control mechanism 80, another possible solution is as follows: a torsion spring is provided at the hinge of the thread-carrying frame 81 to drive the thread-carrying frame 81 to reverse and reset; a protrusion is provided on the turntable 806; when the turntable 806 rotates, the protrusion is used to press down on one end of the thread-carrying frame 81 to make the thread-carrying end tilt upward; after the protrusion passes the thread-carrying frame 81, the torsion spring drives the thread-carrying frame 81 to reverse and reset, causing the thread-carrying end to press down. Although this solution can drive the thread-carrying frame 81 and can achieve engagement and disengagement control through the movement of the thread-carrying frame 81, the reverse reset of the thread-carrying frame 81 makes the speed uncontrollable.
[0046] Preferably, in this application, the end of the wire take-up frame 81 away from the wire take-up has a fork 811. The fork 811 works in conjunction with the corresponding plug-in shaft 8071. During operation, the plug-in shaft 8071 is located inside the fork 811, making the working speed of the wire take-up frame 81 controllable. The disengagement and engagement states are controlled by controlling the relative position of the fork 811 and the plug-in shaft 8071.
[0047] In order to drive the reciprocating movement of the wire take-up frame 81, the clutch control mechanism 50 can be a linear drive mechanism. The front end of the linear drive mechanism has a T-shaped pull joint, and the wire take-up frame 81 has an arc-shaped groove that mates with the T-shaped pull joint. The linear drive mechanism pushes and pulls the T-shaped pull joint to move the wire take-up frame 81. The arc-shaped groove ensures that the wire take-up frame 81 can smoothly complete the swinging motion. However, the linear drive mechanism cannot perform clutch operation after power failure, and the linear drive mechanism requires the operation of a designated button when it needs to work, which has certain operational inconveniences.
[0048] In this application, the clutch control mechanism 50 includes a swing link 508, on which a pin 509 is connected. The take-up shaft 82 is also equipped with a first limiting sleeve 83 and a top-pressure spring 84 located on both sides of the take-up frame 81. When the swing link 508 swings, the pin 509 acts on the first limiting sleeve 83, causing the take-up frame 81 to slide. For ease of operation, the corresponding end of the swing link 508 can extend from the sealing plate 11.
[0049] like Figure 9 As shown, when using the swing linkage 508 directly, to avoid interference between the swing linkage 508 and the wire take-up frame 81, either the length of the first limit sleeve 83 needs to be increased, which would increase the width of the equipment; or the length of the pin 509 needs to be increased, raising the height of the swing linkage 508. However, an excessively long pin 509 is prone to deformation, affecting control reliability. Preferably, in this application, the clutch control mechanism 50 further includes a connecting shaft 506 rotatably mounted on the fixed seat 507 and a pull rod 502 slidably mounted on the support plate 501. Both the fixed seat 507 and the support plate 501 are fixed... The connecting shaft 506 is fixedly installed on the frame 1. Its two ends are connected to the swing connecting rod 508 and the transition connecting rod 505 respectively. The optical shaft 504 installed on the transition connecting rod 505 works in conjunction with the second limiting sleeve 503 set on the pull rod 502. The engagement and disengagement state of the take-up frame 81 is controlled by controlling the movement of the pull rod 502. The pull rod 502 is parallel to the take-up shaft 82 and extends out of the frame 1, which facilitates the engagement and disengagement control operation of the take-up frame 81. It adopts a pure mechanical structure, has a long service life, can be operated at any time, is convenient to use, and is not limited by the position of the device space.
[0050] In this application, the first limiting sleeve 83 and the second limiting sleeve 503 have the same structure, and the limiting sleeve is a sleeve structure with an outer ring groove.
[0051] In this application, the pull rod 502 can be a smooth shaft or a shaft with a threaded section in part, and the threaded section is threadedly connected to the support plate 501. Even after releasing the handle, the take-up frame 81 can remain in a stable separated state, which is convenient for batch replacement of face thread.
[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
