Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a retractable four-piece embroidery device. Background Technology

[0002] Four-gold-sheet embroidery devices typically consist of two double-gold-sheet stacking devices. Both devices feed sheets towards the same needle. In existing technology, four-gold-sheet embroidery devices generally do not have a retraction mechanism. The two stacking devices are stacked one on top of the other or have a notch in the feeding mechanism to allow them to feed sheets towards the same needle without retraction. However, to prevent interference, the cutters corresponding to both stacking devices are set very short. When the needle goes down, the embroidery thread on the needle can easily get stuck in the cutter and be cut, requiring re-threading. This greatly reduces efficiency and affects the embroidery effect. Utility Model Content

[0003] To address the problems of the prior art, this invention provides a retractable four-piece embroidery device. The two pieces do not need to enter the working position simultaneously and can retract from each other, leaving enough space to install the cutter. This prevents the problem of the cutter being too short and causing the thread to get stuck or break.

[0004] The technical solution adopted is as follows:

[0005] A retractable four-piece embroidery device includes a machine head, a first group of gold sheet devices and a second group of gold sheet devices that feed the same needle. Both the first and second groups of gold sheet devices are double-piece stacking feeding devices. The machine head is provided with at least one mounting base. The first and second groups of gold sheet devices are slidably mounted on the mounting base. Each of the first and second groups of gold sheet devices is provided with a retractable mechanism at its upper end. Each retractable mechanism includes a drive motor mounted on the mounting base and a transmission component that drives the corresponding group of gold sheet devices to slide retract or slide forward. A first sliding mechanism is provided between each group of gold sheet devices and the mounting base.

[0006] Furthermore, there are two mounting bases, with one mounting base corresponding to each group of gold sheet devices.

[0007] Furthermore, each set of gold sheet devices is provided with a mounting block at its upper end. The first sliding mechanism includes a first slide rail connected to the corresponding mounting block and a first slider disposed on the corresponding mounting base and cooperating with the first slide rail.

[0008] Furthermore, the transmission assembly is a linkage assembly, including a drive arm and a transmission rod mounted on the corresponding drive motor. One end of the drive arm is mounted on the output shaft of the drive motor, and the other end is connected to the transmission rod. One end of the transmission rod is connected to the drive arm, and the other end is connected to the corresponding mounting block through a connecting block.

[0009] Furthermore, the transmission component is a lead screw and slider assembly, including a lead screw mounted on the corresponding drive motor and a nut slider mounted on the lead screw and cooperating with the lead screw. The nut slider is connected to the corresponding metal plate device, and a sliding structure is provided between the nut slider and the mounting base.

[0010] Furthermore, both the first and second groups of gold sheet devices are equipped with a lifting mechanism.

[0011] Furthermore, the lifting mechanism includes a first connecting plate connected to the corresponding mounting base, a second connecting plate connected to the needle bar frame, and a second sliding mechanism and a drive cylinder disposed between the first and second connecting plates.

[0012] Furthermore, the mechanisms of the first and second sets of gold sheet devices each include a first sheet feeding mechanism, a second sheet feeding mechanism, and a slicing mechanism arranged in layers, and also include a first driving mechanism for driving the first sheet feeding mechanism and the slicing mechanism, and a second driving mechanism for driving the second sheet feeding mechanism.

[0013] Furthermore, a first transmission assembly is provided between the first driving mechanism and the first slice feeding mechanism; a second transmission assembly is provided between the first driving mechanism and the slicing mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention provides a retractable four-piece embroidery device, comprising a first group of embroidery pieces and a second group of embroidery pieces feeding onto the same needle. Each embroidery piece is equipped with a retraction mechanism, which drives the corresponding embroidery piece to retract or enter a working position. With this retraction mechanism, the two embroidery pieces do not need to be in the working position simultaneously, and the cutter on the embroidery piece is not made as short as possible due to space constraints. A cutter of a reasonable length can block the embroidery thread on the needle when the needle is down, preventing the thread from getting stuck at the lower end of the cutter and reducing the likelihood of the thread being cut. Furthermore, there is no need to provide notches or cut surfaces on the embroidery piece to prevent interference, thus reducing processing costs. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] refer to Figure 1-6 A retractable four-piece embroidery device includes a machine head 1, a first set of gold sheet devices 2 and a second set of gold sheet devices 3 that feed the same needle. Both the first and second sets of gold sheet devices are double-piece stacking feeding devices. The machine head 1 is provided with at least one mounting base 5. The first and second sets of gold sheet devices are slidably mounted on the mounting base 5. Each of the first and second sets of gold sheet devices is provided with a retractable mechanism 4 at its upper end. Each retractable mechanism 4 includes a drive motor 401 mounted on the mounting base and a transmission component 402 that drives the corresponding set of gold sheet devices to slide and retract or slide forward. A first sliding mechanism 6 is provided between each set of gold sheet devices and the mounting base 5.

[0024] In one embodiment, the mounting base 5 may be provided, with the first and second groups of gold sheet devices both mounted on the same mounting base 5, but each gold sheet device corresponds to an independent retraction mechanism 4, which can drive the first and second groups of gold sheet devices to slide relative to the mounting base 5 respectively.

[0025] In another embodiment, there are two mounting bases 5, with each set of gold sheet devices corresponding to one mounting base 5.

[0026] Both the first and second sets of gold sheet devices are equipped with a retraction mechanism 4, allowing either the first or second set of gold sheet devices to enter the working position independently without interference. Because of this retraction mechanism, only one set of gold sheet devices enters the working position corresponding to the needle during operation, while the other set retracts under the drive of the retraction mechanism 4. This provides more installation space for the first and second sets of gold sheet devices, preventing the cutters from being made as short as possible due to space constraints. A cutter of a reasonable length can block the embroidery thread on the needle when the needle is down, preventing the thread from getting stuck at the lower end of the cutter and reducing the likelihood of the thread being cut. Furthermore, there is no need to add notches or cut surfaces to the gold sheet devices to prevent interference, reducing processing costs.

[0027] Each set of gold sheet devices is provided with a mounting block 24 at its upper end. The first sliding mechanism 6 includes a first slide rail 601 connected to the corresponding mounting block 24 and a first slider 602 disposed on the corresponding mounting base 5 and cooperating with the first slide rail. The mounting block 24 can slide relative to the mounting base 5, that is, drive the corresponding set of gold sheet devices to slide relative to the mounting base.

[0028] As one implementation method, such as Figure 2 The transmission assembly 402 can be a linkage assembly, including a drive arm 4021 and a transmission rod 4022 mounted on the corresponding drive motor 401. One end of the drive arm is mounted on the output shaft of the drive motor, and the other end is connected to the transmission rod. One end of the transmission rod is connected to the drive arm, and the other end is connected to the corresponding mounting block 24 via a connecting block 4023. When the drive motor 401 rotates, it drives the drive arm 4021 to swing, and the transmission rod 4022 swings accordingly. The transmission rod 4022 drives the connecting block 4023 and the mounting block connected to the connecting block to slide relative to the first slider, that is, it drives the corresponding gold sheet device to slide on the corresponding mounting seat, moving away from the needle bar frame or moving closer to the needle bar frame 19 to enter the working position. Preferably, the mounting seat is also provided with a limiting block 20 to limit the swing range of the drive arm 4021. The limiting block can limit the swing of the drive arm, thereby limiting the sliding range of the first slide rail.

[0029] In another embodiment, the transmission component 402 is a screw-slider assembly (not shown in the figure), including a screw mounted on a drive motor and a nut-slider mounted on and cooperating with the screw. The nut-slider is connected to the gold sheet device. A sliding structure is provided between the nut-slider and the mounting base 5, and a slide rail can be provided on the mounting base to cooperate with the nut-slider for sliding. The drive motor drives the screw to rotate, causing the nut-slider to slide, which in turn causes the corresponding gold sheet device connected to the nut-slider to slide.

[0030] The forward and backward movement of the gold sheet device is driven by an electric motor, which has a fast response speed, better driving effect, and more accurate positioning of the gold sheet device.

[0031] Both the first and second groups of gold sheet devices are equipped with a lifting mechanism 7.

[0032] The lifting mechanism 7 includes a first connecting plate 8 connected to the corresponding mounting base 5, a second connecting plate 9 connected to the needle bar frame, and a second sliding mechanism 10 and a drive cylinder 11 disposed between the first and second connecting plates. The drive cylinder 11 drives the first connecting plate 8 to slide relative to the second connecting plate, thereby lifting the gold sheet device. The second connecting plate 9 is connected to the needle bar frame via a connector 25.

[0033] The structures of the first and second sets of gold sheet devices can be entirely based on existing technology. Each set includes a first feeding mechanism 12, a second feeding mechanism 13, and a slicing mechanism 14 arranged sequentially. It also includes a first driving mechanism 15 for driving the first feeding mechanism and the slicing mechanism, and a second driving mechanism 16 for driving the second feeding mechanism. The first driving mechanism 15 includes a first motor 1501, a first transmission assembly 17 disposed between the first motor 1501 and the first feeding mechanism 12, and a second transmission assembly 18 disposed between the first motor 1501 and the slicing mechanism 14.

[0034] The first and second feeding mechanisms have the same structure, both including a feeding base plate 21 with a feeding groove, a slitting rod 22 for slitting, and a slitting drive rod 23 for driving the slitting rod to slit. The slicing mechanism 14 includes a stacking cutter 1401 for double gold sheets and a drive shaft 1402 for driving the stacking cutter 1401.

[0035] The first transmission assembly 17 includes a feeding drive arm 1701 directly mounted on the first motor 1501 and a feeding transmission rod 1702 located between the paddle drive rod 23 and the feeding drive arm 1701. The feeding drive arm 1701 can also be indirectly connected to the first motor 1501. For example, the feeding drive arm 1701 on the second set of gold sheet devices can be indirectly connected to the first motor 1501 via a synchronous belt assembly (not shown in the synchronous belt diagram). The first motor 1501 drives the feeding drive arm 1701 to swing, which in turn drives the paddle drive rod 23 to swing via the feeding transmission rod 1702.

[0036] The second transmission assembly 18 includes a slicing drive arm 1801 mounted on the first motor 1501, a slicing transmission rod 1802 cooperating with the slicing drive arm, and a connecting rod assembly 1803 located between the slicing drive rod and the drive shaft 1402. The slicing drive arm 1801 and the wafer feeding drive arm 1701 can be set separately or can be the same drive arm, for example, in the first set of gold wafer devices, the wafer feeding transmission rod is driven in the forward direction and the slicing transmission rod is driven in the reverse direction.

[0037] The second drive mechanism 16 is a second motor. The second motor directly drives the paddle drive rod 23 on the second paddle feeding mechanism to swing, thereby driving the corresponding paddle lever to paddle.

[0038] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
