Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a device that can simultaneously or sequentially feed beads and sheets. Background Technology

[0002] Existing multi-functional embroidery machines typically have both bead and sheet feeding mechanisms installed, each with a lifting structure for retraction. To save space, one current design places both mechanisms on the same slide rail. The bead feeding slider connected to the bead feeding mechanism and the sheet feeding slider connected to the sheet feeding mechanism are positioned separately, upper and lower, sliding on the same slide rail, allowing for independent lifting of each mechanism. However, to prevent collisions between the bead and sheet feeding sliders, the two mechanisms cannot operate simultaneously. Due to their different heights, when the upper mechanism slides downwards, the lower mechanism must also slide downwards to avoid collisions. If the lower position is too low, the frame edge will collide with the lower mechanism during embroidery, limiting the frame's range of motion and thus the embroidery area. Utility Model Content

[0003] To address the problems of the prior art, this invention provides a device that can simultaneously or sequentially feed beads and sheets. Without collision between the sheet feeding slider and the bead feeding slider, the sheet feeding mechanism and the bead feeding mechanism can be in the working position at the same time, which is highly efficient and does not interfere with each other.

[0004] The technical solution adopted is as follows:

[0005] A device capable of simultaneously or sequentially feeding beads and sheets includes a mounting frame, a slide rail mounted on the mounting frame, a sheet feeding mechanism and a bead feeding mechanism for feeding materials to the same needle and / or corresponding different needles, the sheet feeding mechanism and the bead feeding mechanism sliding on the same slide rail, a sheet feeding slider between the sheet feeding mechanism and the slide rail, a bead feeding slider between the bead feeding mechanism and the slide rail, the sheet feeding mechanism and the bead feeding mechanism located on the same slide rail, one mechanism being located below and the other above, further including a lifting structure for driving the sheet feeding mechanism to rise and fall along the slide rail, and another lifting structure for driving the bead feeding mechanism to rise and fall along the slide rail, the corresponding lifting structure of the lower mechanism driving the mechanism to descend to a working position, the corresponding lifting structure of the upper mechanism driving the mechanism to descend to a working position, before the sliders collide, the upper mechanism is provided with an extension structure to allow the mechanism to enter the working position, the rising and falling of the sheet feeding mechanism and the bead feeding mechanism does not interfere with the installation.

[0006] Furthermore, the sheet feeding mechanism is located at the top; the bead feeding mechanism is located at the bottom, and the sheet feeding mechanism corresponds to the sheet feeding lifting structure; the bead feeding mechanism corresponds to the bead feeding lifting structure.

[0007] Furthermore, the sheet feeding slider and the ball feeding slider are separately mounted on the slide rail.

[0008] Furthermore, the sheet feeding slider is located above the bead feeding slider, and the bead feeding slider can rise simultaneously with or after the sheet feeding slider; the bead feeding slider can fall simultaneously with or ahead of the sheet feeding slider.

[0009] Furthermore, the upper end of the feeding mechanism is provided with an extension frame that allows the feeding mechanism and the bead feeding mechanism to be in the working position at the same time without interfering with each other.

[0010] Furthermore, the upper end of the extension frame is provided with a switching mechanism that can drive the feeding mechanism to slide in the needle arrangement direction. The switching mechanism is connected to the feeding slider through the feeding connecting frame.

[0011] Furthermore, the feeding mechanism can be a single gold sheet, a multi-gold sheet, or a stacked sheet feeding mechanism.

[0012] Furthermore, the bead-feeding mechanism can be a single-bead or multi-bead feeding mechanism.

[0013] Furthermore, the slide rail is provided with a feeding stop block for the feeding mechanism to slide downwards; the slide rail is also provided with a feeding stop block for the bead feeding mechanism to slide downwards.

[0014] Furthermore, both the sheet feeding lifting structure and the bead feeding lifting structure are driven by cylinders.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a device for simultaneously or sequentially feeding beads and sheets. It includes a slide rail mounted on a mounting frame, a bead feeding mechanism and a sheet feeding mechanism sliding on the same slide rail, one mechanism located at the upper end and the other at the lower end. The slide rail is equipped with a bead feeding slider and a bead feeding lifting structure connected to the bead feeding mechanism, and also with a sheet feeding slider and a sheet feeding lifting structure connected to the sheet feeding mechanism. The corresponding lifting structure of the lower mechanism drives it to descend to the working position, and the corresponding lifting structure of the upper mechanism drives it to descend to the working position. Before the sliders collide, the upper mechanism has an extension structure to allow it to enter the working position. The two mechanisms are installed without interference. This device allows the bead feeding and sheet feeding mechanisms to work simultaneously, improving work efficiency. Only one slide rail is needed to simultaneously lift and lower both the bead and sheet feeding mechanisms, saving space and cost. When the bead and sheet feeding mechanisms are in the working position simultaneously, the sheet feeding base plate and the bead feeding base plate are on the same horizontal plane, eliminating the need to drive the lower mechanism to descend, preventing collisions with the embroidery frame, and not restricting the embroidery range.

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] refer to Figure 1-12 A device for simultaneously or sequentially feeding beads and sheets includes a mounting frame, a slide rail 3 mounted on the mounting frame, a sheet feeding mechanism 1 and a bead feeding mechanism 2 for feeding the same needle and / or corresponding different needles, the sheet feeding mechanism and the bead feeding mechanism sliding on the same slide rail 3, a sheet feeding slider 4 provided between the sheet feeding mechanism 1 and the slide rail 3, a bead feeding slider 6 provided between the bead feeding mechanism 2 and the slide rail 3, the sheet feeding mechanism 1 and the bead feeding mechanism 2 located on the same slide rail, one mechanism being located below and the other above, further including a lifting structure for driving the sheet feeding mechanism 1 to rise and fall along the slide rail, and another lifting structure for driving the bead feeding mechanism 2 to rise and fall along the slide rail, characterized in that: the corresponding lifting structure of the lower mechanism drives the mechanism to descend to the working position, and the corresponding lifting structure of the upper mechanism drives the mechanism to descend to the working position, before the sliders collide, the upper mechanism is provided with an extension structure to allow the mechanism to enter the working position, and the rising and falling of the sheet feeding mechanism 1 and the bead feeding mechanism 2 does not interfere with the installation.

[0027] The feeding mechanism 1 and the bead feeding mechanism 2 can feed materials to the same needle or to different corresponding needles, because the feeding mechanism 1 can switch between different needles to feed materials to different needles. In this embodiment, the feeding mechanism 1 and the bead feeding mechanism 2 correspond to the same needle.

[0028] It must be ensured that at least one state is maintained: when the sheet feeding mechanism enters the sheet feeding station, the bead feeding mechanism is also in the bead feeding station. This allows sheet feeding mechanism 1 and bead feeding mechanism 2 to feed beads simultaneously, enabling the machine needle to embroider both sequins and beads in a single stitch. Alternatively, sheet feeding mechanism 1 and bead feeding mechanism 2 can feed materials sequentially, with the machine needle embroidering sequins and beads sequentially. This improves efficiency and increases the variety of embroidery styles, allowing for patterns with alternating sequins and beads. Of course, sheet feeding and bead feeding can also be performed separately.

[0029] The feeding station and the bead feeding station are at the same height, and when in the working position, the bead feeding base plate and the feeding station are on the same horizontal plane. This prevents the feeding mechanism 1 or the bead feeding mechanism 2 from being lowered below the working position to avoid interference. The feeding mechanism 1 and the bead feeding mechanism 2 are less likely to collide with the outer frame of the embroidery frame, thus not restricting the embroidery area.

[0030] The feeding mechanism 1 corresponds to the feeding lifting structure 5; the bead feeding mechanism 2 corresponds to the bead feeding lifting structure 7. The feeding slider 4 and the bead feeding slider 6 are separately mounted on the slide rail. The feeding lifting structure 5 can drive the feeding mechanism 1 to rise and fall, and drive the feeding slider 4 to slide up and down along the slide rail 3; the bead feeding lifting structure 7 can drive the feeding mechanism 2 to rise and fall, and drive the bead feeding slider 6 to slide up and down along the slide rail 3.

[0031] The slide rail is equipped with a sheet feeding stop block 11 to prevent the sheet feeding mechanism from sliding downwards; the slide rail is also equipped with a bead feeding stop block 12 to prevent the bead feeding mechanism from sliding downwards. The sheet feeding stop block and the bead feeding stop block are directly or indirectly connected to the slide rail. The sheet feeding stop block 11 cooperates with the sheet feeding connecting frame 10 to prevent the sheet feeding mechanism from sliding downwards and to prevent the sheet feeding slider from colliding with the bead feeding slider. The bead feeding stop block 12 cooperates with the bead feeding connecting frame 20 to prevent the bead feeding slider from disengaging from the slide rail and to limit the descent height of the bead feeding mechanism 2.

[0032] Both the sheet feeding lifting structure 5 and the bead feeding lifting structure 7 are driven cylinders. One end of the cylinder in the sheet feeding lifting structure 5 is connected to the connecting rail, and the other end is connected to the sheet feeding connecting frame 10; one end of the cylinder in the bead feeding lifting structure 7 is connected to the connecting rail, and the other end is connected to the bead feeding connecting frame 20.

[0033] The feeding mechanism 1 can be a single gold sheet, a multi-gold sheet, or a stacked sheet feeding mechanism.

[0034] The bead-feeding mechanism 2 can be a single-bead or multi-bead feeding mechanism.

[0035] In this embodiment, the sheet feeding mechanism 1 is a three-sheet stacking sheet feeding mechanism; the bead feeding mechanism 2 is a four-bead bead feeding mechanism. Preferably, the sheet feeding mechanism 1 is located at the top; the bead feeding mechanism 2 is located at the bottom, and the sheet feeding slider 4 is located at the top of the bead feeding slider 6.

[0036] The extension structure is an extension frame 8 mounted on the sheet feeding mechanism 1. Compared to the height of the bead feeding mechanism 2, the overall height of the sheet feeding mechanism 1 is lower, and the sheet feeding slider 4 is located above the bead feeding slider 6. Therefore, preferably, the upper end of the sheet feeding mechanism 1 is provided with an extension frame 8 that allows the sheet feeding and bead feeding mechanisms to be in working positions simultaneously without interfering with each other. This ensures that the sheet feeding mechanism 1 and the bead feeding mechanism 2 can be in working positions simultaneously, and that the sheet feeding slider 4 and the bead feeding slider 6 will not collide. The extension frame 8 can be set to an appropriate length as needed, ensuring that the sliders do not collide while also guaranteeing the sliding amount of the sheet feeding mechanism. When the sheet feeding slider and the bead feeding slider 6 happen to collide, the sheet feeding mechanism 1 and the bead feeding mechanism 2 are in working positions simultaneously. At this time, the length of the extension frame 8 is a critical value. The length of the extension frame 8 can be set according to this critical value, making it greater than the critical value, to avoid the sliders colliding.

[0037] The sheet feeding slider 4 is located above the bead feeding slider 6. The bead feeding slider 6 can rise simultaneously with or after the sheet feeding slider 4; the bead feeding slider can also fall simultaneously with or ahead of the sheet feeding slider 4. The sheet feeding mechanism 1 and the bead feeding mechanism 2 can rise and fall simultaneously, or the sheet feeding mechanism 1 can be driven to rise first for retraction.

[0038] The upper end of the extension frame 8 is provided with a switching mechanism 9 that can drive the feeding mechanism 1 to slide in the needle arrangement direction. The switching mechanism 9 is connected to the feeding slider 4 through the feeding connecting frame 10.

[0039] The switching mechanism 9 includes a drive motor 901 and a drive block 902 mounted on the output shaft of the drive motor 901. The drive block 902 has two drive cams 903. A sliding structure 13 is provided between the extension frame 8 and the connecting frame 10. The sliding structure 13 includes a slider 1301 connecting the extension frame and a slide rail 1302 mounted on the connecting frame. The upper end of the slider 1301 has several spaced-apart switching blocks 14 that cooperate with the drive block. The gap between two adjacent switching blocks 14 allows the drive cams to pass through. However, curved grooves 22 that cooperate with the drive cams 903 are provided between the switching blocks 14 at both ends and their adjacent switching blocks 14 to prevent the slider from disengaging from the slide rail. The drive motor 901 drives the drive block 902 to rotate, causing the drive cams 903 to cooperate with the switching blocks 14, driving the switching blocks 14 to slide, thereby causing the feeding mechanism 1 to slide and switch different needles. If the bead feeding mechanism 2 needs to be raised or lowered or operated independently, the bead feeding mechanism 1 can also be driven to retreat by the switching mechanism 9.

[0040] The feeding mechanism 1 includes an end base 19, a feeding base plate 101, a first feeding mechanism 15, a second feeding mechanism 16, a third feeding mechanism 17 arranged sequentially from top to bottom on the upper end of the feeding base plate 101, and a slicing mechanism 18. The first feeding mechanism 15 is provided with a first prying assembly 1501, a first motor 1502 driving the first prying assembly, and a first transmission assembly 1503. The second feeding mechanism 16 is provided with a second prying assembly 1601, a second motor 1602 driving the second prying assembly, and a second transmission assembly 1603. The third feeding mechanism 17 is provided with a third prying assembly 1701, a third motor 1702 driving the third prying assembly, and a third transmission assembly 1703. It also includes a corresponding cutter assembly 1801 and a cutter transmission assembly 1802. The first motor 1502 also drives the slicing mechanism 18.

[0041] The first, second, and third motors are all mounted on the same side of the end base 19. The cutter drive assembly 1802 is located on the other side of the end base 19 where the motors are mounted, and the cutter assembly 1801 is located on the end of the feeding plate 101 away from the end base 19. Placing the motors on the same side reduces the lateral space they occupy, making it suitable for embroidery machines with a smaller head-to-ground distance. The fact that the cutter assembly 1801 is away from the end base 19 prevents interference between it and the bead feeding mechanism 2. Alternatively, a notch can be provided on the feeding plate to avoid interference with the bead feeding mechanism 2, thus not affecting the installation of the cutter assembly.

[0042] The bead feeding mechanism 2 includes a first bead feeding structure 201 and a corresponding first bead feeding drive structure 2011; a second bead feeding structure 202 and a corresponding second bead feeding drive structure 2021; a third bead feeding structure 203 and a corresponding third bead feeding drive structure 2031; and a fourth bead feeding structure 204 and a corresponding fourth bead feeding drive structure 2041.

[0043] The first to fourth bead feeding structures and their corresponding bead feeding drive structures can all employ existing technologies. The four bead feeding structures can be mounted on the same bead feeding base plate, and each bead feeding structure includes a bead feeding clamp assembly. Each bead feeding drive structure includes a drive motor and a transmission assembly located between the bead feeding structure and the drive motor. The drive motors in the bead feeding structures are staggered vertically.

[0044] Each bead feeding mechanism is equipped with a corresponding bead supply device 21 at its upper end. The bead supply device can adopt existing technology, such as each bead supply device including a material cylinder 2101, a material supply container 2102, a bead guide rod 2102, and several bead clamping structures 2103 arranged vertically. The above description is only an optional embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the content of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
