Description

TECHNICAL FIELD

[0001] One or more embodiments of the present disclosure relate to the technical field of embroidery machines, in particular to a disc tape embroidery device and an embroidery machine. BACKGROUND

[0002] The disc tape embroidery device is used for embroidering tape and / or rope and the like. The disc tape embroidery device generally comprises a machine shell, a driving main shaft, a needle bar, a feeding part, a presser foot, and a thread tensioning lever. The existing feeding part adopts a disc to carry a large capacity of tape. During the disc tape embroidery operation, the needle of the machine is lowered to pierce the embroidery material, and the face thread locks the rope or tape on the embroidery material. At this time, the embroidery frame is moved, which will move the rope / tape. When the size of the disc increases, the rope or tape will be mechanically pulled out of the disc. There is a large pulling force between the embroidery frame and the disc, which will deform the embroidery product and cause the embroidery product to be defective.

[0003] In some related technologies, the embroidery machine uses a rope collecting mechanism and a tensioning mechanism to realize the winding and unwinding of the tape. However, the rope collecting mechanism and the tensioning mechanism have a complex structure, and when they are externally mounted on the machine head, they increase the load of the overall disc tape embroidery device and affect the high-speed operation of the disc tape embroidery device.

[0004] In the prior invention patent CN113584748B of the applicant, the disc tape embroidery device is provided with a feeding frame, and the rope or tape conveyed on the disc is conveyed to the presser foot mounting member of the presser foot after passing through the feeding frame. The patent controls the lifting of the feeding frame to pull and lower the rope or tape conveyed on the disc. Although the feeding frame has a relatively simple structure compared to the rope collecting mechanism and the tensioning mechanism, in actual application, the tape is prone to turning over after being fed from the disc into the feeding frame and then passing out of the feeding frame. When the turned-over tape is locked by the face thread, the embroidery pattern of the embroidery product is distorted, which reduces the quality of the embroidery product. Moreover, as the disc continues to rotate, the turned-over tape is pressed tighter, and there will be a large pulling force between the embroidery frame and the disc, which will deform the embroidery product and even break the tape. UTILITY MODEL CONTENT

[0005] One or more embodiments of the present disclosure describe a disc tape embroidery device and an embroidery machine, which aim to solve one or more of the above problems and other potential problems.

[0006] In a first aspect, the embodiments of the present disclosure provide a disc and belt embroidery device.

[0020] The preferred embodiments of the present disclosure will be described in detail with reference to the drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0022] As mentioned earlier, ribbon embroidery requires a feed tray to transport the ribbon (such as rope or ribbon) to the presser foot. The needle inserts into the fabric, and the top thread locks the ribbon onto the fabric. Continuous operation completes the ribbon embroidery. During ribbon embroidery, the top thread holds the ribbon to the fabric. Moving the embroidery frame at this time will move the ribbon. The ribbon will be pulled off the feed tray by the embroidery frame. The larger the feed tray, the greater the pulling force, which may deform the embroidery and result in defective work.

[0023] In the applicant's prior invention patent, the ribbon embroidery device is equipped with a feeding frame for extracting and lowering the ribbon from the tray, preventing the ribbon from becoming taut due to the frame's pull when the embroidery frame is moved. While this structure can address the problem of deformation caused by excessive tension to some extent, the ribbon, generally having a certain width, has a high probability of flipping over (i.e., not being flattened) during its journey from the tray to the feeding frame and then from the feeding frame to the presser foot. When the flipped ribbon is locked by the fabric, the ribbon embroidery becomes uneven. Furthermore, the feeding frame exerts a certain pressure on the flipped ribbon, and this pressure increases as the tray rotates. When the embroidery frame is moved, the tension between the frame and the tray further exacerbates the pressure on the ribbon, still causing deformation and affecting the quality of the embroidery.

[0024] In response to this, according to the embodiments of this disclosure, a simple feeding ring is designed to replace the feeding frame, so that when it is installed on the tape embroidery device, the tape can be pulled out from the material tray and fed into the feeding ring, and the feeding ring can output the flattened tape to the presser foot, ensuring that the tape locked by the top thread is smooth and the embroidery quality is high.

[0025] Figure 1 A schematic diagram of the structure of a ribbon embroidery device 10 according to an embodiment of the present disclosure is shown. Figure 1 As shown, the ribbon embroidery device 10 includes a housing 101, a needle bar section, a presser foot section, and a material tray section 102. The needle bar section includes a needle bar 103 and a needle bar drive mechanism, with the needle bar 103 vertically passing through the housing. The needle bar drive mechanism includes a cam and a linkage mechanism for driving the needle bar 103 to move up and down. The presser foot section includes a presser foot mounting part 110 and a presser foot sleeve 104. The presser foot sleeve 104 is fitted over the needle bar 103, and the presser foot mounting part 110 is connected to the presser foot sleeve 104. The presser foot mounting part 110 is used to mount the presser foot and a nozzle (not shown in the figure, where the presser foot is used for threading ribbon, and the nozzle is used for threading rope). The material tray section 102 includes a material tray frame and a material tray, with one or more material trays mounted on the frame. The material trays are used to convey ribbons or other strips to the area to be embroidered for ribbon embroidery.

[0026] like Figure 1As shown, the disc and tape embroidery device 10 further comprises a rotating driving mechanism 109 mounted on the casing 101 for driving the disc holder of the disc part 102 to rotate. The disc holder is fixed on the first shaft sleeve 105 which is sleeved on the presser foot sleeve 104, and the first shaft sleeve 105 is rotationally connected on the casing 101 or the beam of the embroidery machine. The first shaft sleeve 105 rotates under the driving of the rotating driving mechanism 109, thereby driving the disc holder to rotate.

[0027] As shown, Figure 1 The disc and tape embroidery device 10 further comprises a second shaft sleeve 106, a feeding ring 107, and a feeding driving mechanism 108. The second shaft sleeve 106 is sleeved on the first shaft sleeve 105, and the feeding ring 107 is mounted on the second shaft sleeve 106. The feeding driving mechanism 108 is arranged on the casing 101 for driving the second shaft sleeve 105 to move up and down, thereby driving the feeding ring 107 to move up and down in the vertical direction, and realizing the pulling and dropping of the tape during the up and down movement. When the first shaft sleeve 105 rotates under the driving of the rotating driving mechanism 109, the second shaft sleeve 106 rotates under the driving of the first shaft sleeve 105, so that the feeding ring rotates with the disc.

[0028] In some embodiments, the feeding ring 107 can be configured according to the number of discs. That is, when there is one disc, one feeding ring is configured and arranged close to the disc. When there are two discs, two feeding rings are configured, and each feeding ring is arranged close to one disc. As shown, Figure 1 The disc and tape embroidery device 10 has two discs, and the two feeding rings 107 are respectively mounted on the two sides of the second shaft sleeve 106. In this way, the rope or tape conveyed on the disc can pass through the feeding ring 107 and be fed into the presser foot or the nozzle.

[0029] In some embodiments, the feeding ring 107 can be a closed ring or an unclosed ring with a gap, such as a three-quarter circular ring or a semi-circular ring. In this way, the rope or tape can enter the feeding ring 107 in any direction along the circumferential surface, which can adapt to the tape entering from various directions when the disc rotates. At the same time, the circumferential surface can guide the smooth movement of the tape.

[0030] In some embodiments, the feeding ring 107 has an arc-shaped concave surface at the feeding port, and the arc-shaped concave surface is horizontally downward. As shown, Figure 1As shown, the ribbon generally enters from above the feed ring 107 and exits from below, and is then fed to the lower presser foot or tube. The entry from above is the entry port, and the exit from below is the exit port. The end face of the feed ring 107 at the entry port is a circular arc end face that extends downward toward the center of the entry port, so that the diameter of the entry port gradually decreases, and the overall shape is concave, which is defined as an arc-shaped concave surface in the embodiments of the present disclosure. In this way, the ribbon with a certain width can enter from the arc-shaped concave surface, and the arc-shaped concave surface can facilitate smooth entry and flattening of the ribbon, and at the same time, the ribbon is introduced downward along the direction of the arc-shaped concave surface (mainly horizontally downward) to the presser foot or tube. In some examples, the ribbon can be made to enter the feed ring 107 obliquely and be vertically guided out of the feed ring 107, and then be inserted into the presser foot or tube.

[0031] In some embodiments, the arc-shaped concave surface of the feed ring 107 is arranged toward the corresponding tray on the tray rack. In this way, the ribbon can be guided to enter and exit to the presser foot or tube of the presser foot portion. In an example, the feed ring 107 can be vertically arranged on the disc ribbon embroidery device 10. For example, the entry port and the exit port of the feed ring 107 are arranged on the same vertical line. In another example, the feed ring 107 can be arranged obliquely on the disc ribbon embroidery device 10. For example, the entry port is arranged close to the tray on the same side, and the exit port is arranged close to the center of the tray.

[0032] Figure 2 A structural schematic diagram of the feed ring 107 according to an embodiment of the present disclosure is shown. The feed ring 107 can be a feed sleeve structure with an arc-shaped concave surface 107-1. The ribbon enters from the arc-shaped concave surface 107-1 of the feed ring 107 and is guided out downward. With the arc-shaped guidance, the ribbon is flattened and guided out vertically downward after passing through the arc-shaped concave surface. In Figure 2 In an example, the feed ring 107 has a certain thickness, which can better guide the ribbon to be guided out in a flattened state. In other examples, the feed ring 107 can be a thin sheet ring.

[0033] In Figure 2 In the example shown, the feed ring 107 includes an upper ring portion and a lower ring portion, and the outer diameter of the upper ring portion is greater than the outer diameter of the lower ring portion. In some embodiments, the feed ring 107 can also be a ring with other structural forms, such as a cylindrical ring formed by the upper and lower ring portions with equal outer diameters.

[0034] Figure 3 A structural schematic diagram of the feed ring 107 mounted on the second shaft sleeve 106 by the mounting member 111 according to an embodiment of the present disclosure is shown. As Figure 4As shown, the mounting member 111 can be a mounting plate, which is fixed on the second shaft sleeve 106, for example, can be fixed outside the second shaft sleeve 106, or can be fixed inside the second shaft sleeve. In some embodiments, the mounting member 111 also has a mounting hole, allowing the feeding ring member 107 to be sleeved in the mounting hole. The feeding ring member 107 can be matched with the mounting hole, without relative rotation. In some embodiments, the mounting member 111 can also be welded with the feeding ring member 107, or be fixed by screwing, or be fixed by screw.

[0035] In some embodiments, the mounting member 111 can be used to tilt the feeding ring member 107. In this way, the arc-shaped concave surface of the feeding ring member 107 can be directed towards the tray. In an example, the mounting member 111 can be an obtuse angle connector, or can be a connector of other forms. In some embodiments, the mounting member 111 can be used to vertically mount the feeding ring member 107. The mounting member 111 can be a right angle connector, or can be a connector of other forms.

[0036] In some embodiments, there are several feeding ring members 107, each corresponding to a tray on the tray rack, and each is mounted on the second shaft sleeve 106. In some examples, each feeding ring member is mounted on the second shaft sleeve 106 by a mounting member, for example Figure 3 the structure shown. In some examples, several feeding ring members can be mounted on the second shaft sleeve 106 by a mounting member. In an example, the mounting member can be a ring-shaped plate, used to fix several feeding ring members.

[0037] Figure 4 A schematic diagram of the transmission structure between the feeding ring member 107 and the driving mechanism for driving the rotation and lifting of the feeding ring member 107 according to an embodiment of the present disclosure is shown. As shown Figure 4 , the feeding driving mechanism includes a feeding motor 108-1, a transmission structure 108-2, and a driving rod 108-3. The motor shaft of the feeding motor 108-1 drives the transmission structure 108-2 to drive the driving rod 108-3 connected with the transmission structure 108-2 to lift. The transmission structure can be realized by using transmission components such as pulleys or sprockets. In an example, the transmission structure is composed of a transmission belt, a driving pulley, and a driven pulley. The motor 108-1 drives the driving pulley to rotate, and the driven pulley rotates under the transmission of the transmission belt. The transmission structure 108-2 is connected with one end of the driving rod 108-3, and the driving rod 108-3 can be controlled to lift during the transmission of the transmission belt. The other end of the driving rod 108-3 is connected with the second shaft sleeve 106 (for example, the connection between the driving rod 108-3 and the second shaft sleeve 106 is realized by the driving fork structure in Figure 4 ), and the other end of the driving rod 108-3 lifts with the second shaft sleeve 106. Accordingly, the feeding ring member 107 connected with the second shaft sleeve 106 also lifts.

[0038] AsFigure 4 As shown, the rotary drive mechanism includes a rotary drive motor 109-1, a transmission rod 109-3, and a transmission assembly 109-2. In some embodiments, the transmission assembly may adopt a master-slave pulley transmission structure. The transmission assembly 109-2 includes a driving pulley, a belt, and a driven pulley. The rotary drive motor 109-1 drives the transmission rod 109-3 to rotate, thereby causing the transmission assembly connected to the transmission rod 109-3 to rotate as well. The first bushing 105, which is connected to the driven pulley, also rotates, thereby driving the material tray frame to rotate, and the feeding ring 107 mounted on the second bushing 106 to rotate. In some embodiments, the rotary drive mechanism can be used alone for material tray rotation, i.e., as a presser foot rotary drive mechanism. Accordingly, the presser foot rotation is achieved through another presser foot rotary drive mechanism. For example, in the applicant's prior invention patent CN113584748B, the presser foot rotary drive mechanism includes a presser foot drive motor and a transmission assembly. The presser foot drive motor drives the transmission assembly to operate, thereby driving the presser foot sleeve to rotate, thereby driving the presser foot or nozzle to rotate. In some embodiments, a single rotary drive mechanism is used, which can simultaneously drive the presser foot or nozzle and the material tray frame to rotate synchronously. The rotary drive motor drives the transmission assembly to rotate the first bushing, and the presser foot sleeve rotates with the first bushing to drive the presser foot or nozzle at the presser foot part to rotate. At the same time, the material tray frame is mounted on the first bushing, and the material tray frame and the feeding frame also rotate synchronously.

[0039] Embodiments of this disclosure also provide an embroidery machine, including an embroidery frame and a plurality of embroidery machine heads. The plurality of embroidery machine heads includes a plurality of flat embroidery device heads and a plurality of ribbon embroidery device heads. The ribbon embroidery device can employ... Figure 1 The illustrated ribbon embroidery device 10. Multiple embroidery heads (flat embroidery devices) are synchronized via a main shaft driving the needle bars. The main shaft is also connected to a camshaft on the ribbon embroidery device, which in turn drives the cam and linkage mechanism to achieve the movement of the needle bars on the ribbon embroidery device. When the ribbon embroidery device and the flat embroidery device are mounted on a single computerized embroidery machine, mechanical wear and thread loosening problems caused by the ribbon embroidery device moving with the flat embroidery device during operation are avoided. The ribbon embroidery device also includes a separation mechanism, allowing it to disengage from the main shaft and stop rotating during flat embroidery operations.

[0040] The embodiments described above are merely preferred embodiments of this disclosure and are not intended to limit the scope of this disclosure. Any modifications and improvements made by those skilled in the art to the technical solutions of this disclosure without departing from the spirit of this disclosure shall fall within the protection scope defined by the claims of this disclosure.
