Description

Technical Field

[0001] This utility model relates to the field of sequin embroidery technology, and in particular to a pressing mechanism and a feeding device for sequin embroidery. Background Technology

[0002] In sequin embroidery, a feeding device is used to transport sequins. A lever moves the sequin to the working position for slicing, after which the needle bar sews it in place. Existing feeding devices include a feeding base plate for transporting the sequins, with a feeding groove on the base plate. Near the needle bar, a fixed blade is also provided for cooperating with the slicing blade. The upper end of the feeding groove has a pressing mechanism for positioning the sequins. In existing technology, the pressing mechanism is generally mounted on a mounting base of the feeding device. The pressing mechanism includes a pressing spring for pressing the sequins, a rotating shaft for mounting the pressing spring, a return torsion spring that presses the pressing spring against the feeding groove, and a drive wrench that drives the rotating shaft to rotate and lift the pressing spring. When installing the sequin, one hand needs to operate the drive wrench to lift the pressing spring, while the other hand inserts the sequin into the feeding groove. After installation, the drive wrench is released, and the pressing spring, driven by the return torsion spring, returns to its original position and presses down on the sequin. Because the pressure spring needs to be lifted with one hand during installation, the gold sheet can only be inserted into the feed slot with one hand, which is very inconvenient and results in low efficiency in installing the gold sheet.

[0003] Multi-sheet feeding devices typically consist of multiple stacked feeding base plates, each corresponding to a pressing mechanism. Because these devices usually simultaneously feed gold sheets of different sizes or with eccentrically positioned holes, the position of the corresponding feeding base plate must be adjusted as needed. This ensures that the needles on the gold sheets of different sizes and specifications fed from the stack can simultaneously engage with the needles, allowing the cutting blade to cut the sheets of different sizes or with different hole positions at the same time. Since the pressing mechanism and the feeding base plate are separate, moving the feeding base plate while keeping the pressing spring in place will change the engagement position between the pressing spring and the feeding base plate. The angle of the pressing spring needs to be adapted to the gold sheets fed from the feeding base plate for better sheet fixation. In existing technologies, the engagement position between the feeding base plate and the pressing spring changes after the feeding base plate moves, requiring the pressing spring to adjust its rotation angle to re-engage with the feeding base plate. Therefore, when changing sheets, both the feeding base plate and the pressing spring need to be adjusted separately, which is cumbersome, time-consuming, and labor-intensive. Meanwhile, because it is necessary to ensure the engagement angle between the sheet conveying base plate and the pressure spring, the adjustment of the sheet conveying base plate's position is greatly affected and restricted. Therefore, the adjustment range of the upper and lower stacked sheets conveyed by the existing stacking sheet feeding device is relatively small. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides a pressing mechanism and a feeding device for sequin embroidery. The two states of the pressing spring can be easily switched manually, making it more convenient to thread the sequins. The pressing mechanism is directly mounted on the feeding base plate. After the feeding base plate moves, there is no need to adjust the angle of the pressing spring to match the feeding base plate, saving time and effort.

[0005] The technical solution adopted is as follows:

[0006] A pressing mechanism for sequin embroidery includes a feeding base plate for conveying sequins and a pressing mechanism body disposed on the feeding base plate. The pressing mechanism body includes a pressing spring that cooperates with the sequins fed on the feeding base plate and a rotating shaft for mounting the pressing spring. The feeding base plate is provided with a mounting block. The rotating shaft is rotatably disposed on the mounting block. The rotating shaft is provided with a torsion spring that can drive the pressing spring to cooperate with the feeding base plate. One end of the torsion spring drives the pressing spring, and the other end is connected to the mounting block. When the other end of the torsion spring is connected to the mounting block, it drives the pressing spring to cooperate with the base plate to press the sequins. When the other end of the torsion spring is disengaged from the mounting block, it disengages from driving the pressing spring. The torsion spring is a helical torsion spring or a non-helical spring that can generate torsional force.

[0007] Furthermore, the connection structure includes a hook located at the other end of the torsion spring and mounted on the mounting block; the other end of the torsion spring is provided with a ring.

[0008] Furthermore, the connection structure includes a hook on the other end of the torsion spring and a ring on the mounting block that engages with the hook.

[0009] Furthermore, the feeding plate is provided with a pressure plate, and the pressure plate is provided with a groove for accommodating the pressure spring.

[0010] Furthermore, one end of the torsion spring is located on the rotating shaft, and the other end is connected to or disconnected from the mounting block.

[0011] Furthermore, the wafer feeding base plate is provided with a wafer feeding groove for wafer feeding.

[0012] Furthermore, the slide feeding base plate is provided with a fixed blade for slicing at one end near the needle bar, and a slide insertion groove for inserting slides at the other end away from the needle bar.

[0013] A tablet feeding device includes a mounting base, at least one tablet feeding mechanism and a cutting assembly disposed on the mounting base. The tablet feeding mechanism includes a tablet feeding base plate and a tablet pressing mechanism that cooperates with the tablet feeding base plate. A tablet feeding drive mechanism is also provided at a corresponding location of the tablet feeding mechanism. The device also includes a cutting drive mechanism for driving the cutting assembly to slice tablets. The tablet pressing mechanism is any of the tablet pressing mechanisms described above, and the tablet pressing mechanism is disposed on at least one tablet feeding mechanism.

[0014] Furthermore, it includes a first feeding mechanism, a second feeding mechanism, and a third feeding mechanism arranged in a vertically stacked manner. The pressing mechanism is located on at least one of the three feeding mechanisms. The first, second, and third feeding mechanisms are respectively provided with a first feeding drive mechanism, a second feeding drive mechanism, and a third feeding drive mechanism. The cutting assembly includes a stacking cutter that cooperates with the three feeding mechanisms. The cutting drive mechanism includes a first motor and a cutting transmission assembly located between the first motor and the cutting assembly.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a pressing mechanism and a feeding device for sequin embroidery. The pressing mechanism includes a pressing spring and a mounting block on the feeding base plate. A rotating shaft for mounting the pressing spring is rotatably connected to the mounting block. A torsion spring is mounted on the rotating shaft, with one end fixed to the rotating shaft and the other end connectable or disconnectable from the mounting block. When the torsion spring is suspended on the side of the mounting block away from the pressing spring, the pressing spring is away from the working position, allowing the sequin to easily pass under the pressing spring without rotating the rotating shaft, which is very convenient. When pressing is required, the torsion spring is manually rotated to connect and position with the mounting block, driving the rotating shaft to move the pressing spring into the working position and press the sequin. The operation is simple and allows for quick switching. When changing sequins, the torsion spring is disconnected from the mounting block, allowing the torsion spring to return to its original position. For multi-plate feeding devices, when the feeding base plate needs to be moved to change plates, the pressing mechanism is directly mounted on the feeding base plate and can move with the feeding base plate. Compared with the pressing mechanism that is fixedly mounted on the feeding device mounting base, after the feeding base plate is moved, there is no need to disassemble the pressing spring to adjust the angle and re-fit with the feeding base plate, which saves time and effort.

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

[0023] refer to Figure 1-6 A pressing mechanism for sequin embroidery includes a feeding base plate 1 for conveying sequins and a pressing mechanism body 2 disposed on the feeding base plate 1. The pressing mechanism body 2 includes a pressing spring 201 that cooperates with the sequins fed on the feeding base plate and a rotating shaft 202 for mounting the pressing spring 201. The feeding base plate 1 is provided with a mounting block 203. The rotating shaft is rotatably disposed on the mounting block 203. The rotating shaft is provided with a torsion spring 3 that can drive the pressing spring 201 to cooperate with the feeding base plate 1. One end of the torsion spring drives the pressing spring 201, and the other end is provided with a connecting structure 4 between it and the mounting block 203. When the other end of the torsion spring is connected to the mounting block, the driving pressing spring cooperates with the base plate to press the sequins; when the other end of the torsion spring is disengaged from the mounting block, the torsion spring disengages from the driving pressing spring. The torsion spring is a helical torsion spring or a non-helical spring that can generate torsional force.

[0024] When the torsion spring is disengaged from the mounting block, one end is suspended on the side of the mounting block 203 away from the pressure spring. At this time, the torsion spring is disengaged from the pressure spring 201, and there is enough space between the feeding base plate 1 and the pressure spring 201 for the gold sheet to be inserted. At this time, the sheet can be inserted without rotating the shaft, which can realize the insertion of the sheet by both hands, making the insertion more convenient and easier to adjust the position of the gold sheet, resulting in high insertion efficiency.

[0025] In one embodiment, one end of the torsion spring 3 is mounted on the rotating shaft 202, and the other end is connected to or disconnected from the mounting block. After the sheet is threaded, the torsion spring is manually rotated to connect with the mounting block 203, i.e., the torsion spring is driven to rotate towards the side closer to the pressure spring. At this time, the rotating shaft rotates, causing the pressure spring 201 to press down on the gold sheet on the sheet feeding base plate 1, positioning the gold sheet. If it is necessary to change the sheet and re-thread it, the torsion spring 3 is manually driven to disconnect from the mounting block 203. At this time, the torsion spring 3 returns to its original position, the rotating shaft returns to its original position, and the pressure spring 201 moves away from the working position and returns to its initial position, allowing threading to be performed again.

[0026] In this embodiment, the connecting structure 4 includes a hook 402 located at the other end of the torsion spring and mounted on the mounting block 203 for connection and engagement; the other end of the torsion spring is provided with a ring 401. The ring at one end of the torsion spring can serve as a handle, facilitating manual pushing of the torsion spring to connect with the mounting block. Alternatively, the hook can also be located at one end of the torsion spring (not shown in the figure), with a ring or a round hole on the mounting block for engagement with the hook to position the torsion spring.

[0027] The feeding plate 1 is provided with a pressure plate 28, and the pressure plate 28 has a groove 29 for accommodating the pressure spring. The feeding plate 1 is provided with a feeding groove 5 for feeding the sheet, and a fixed blade for slicing is provided at one end of the feeding plate 1 near the needle bar. The feeding plate 1 is provided with a slicing groove 6 for threading the sheet at the other end away from the needle bar. The gold sheet is threaded through the slicing groove 6 into the feeding groove 5 and transported to the fixed blade, where the moving blade and the fixed blade cooperate to slice the sheet.

[0028] For multi-sheet feeding devices, the position of the cutter should be adapted to the size of the sheet. If it is necessary to replace the sheet with a different size or to offset the sheet, the corresponding feeding base plate 1 needs to be moved, the distance between the feeding base plate 1 and the needle bar needs to be adjusted, and the thickness of the moving blade needs to be adjusted to match the fixed blade. Since the tablet pressing mechanism body 2 is directly mounted on the feeding base plate 1, the movement of the feeding base plate 1 will drive the tablet pressing mechanism body 2 to move together, eliminating the need to readjust the angle of the pressing spring, thus saving time and effort. In the existing technology, the feeding base plate 1 needs to be moved separately, and the pressing mechanism is fixed on the mounting base. After the feeding base plate 1 moves, the matching position with the pressing spring changes, requiring readjustment of the pressing spring angle and disassembly of the torsion spring that drives the pressing spring to rotate, which is very troublesome, time-consuming, labor-intensive, and inefficient.

[0029] The tablet pressing mechanism of this utility model can be used in single-sheet feeding devices or multi-sheet feeding devices. The feeding device includes a mounting base 7, at least one feeding mechanism 8 and a cutting assembly 9 disposed on the mounting base 7. The feeding mechanism 8 includes a feeding base plate and a tablet pressing mechanism that cooperates with the feeding base plate. A feeding drive mechanism 11 is also provided at the corresponding position of the feeding mechanism 8. It also includes a cutting drive mechanism 12 that drives the cutting assembly 9 to cut the sheets. The tablet pressing mechanism is disposed on at least one feeding mechanism 8.

The first, second, and third feeding mechanisms are respectively provided with a first feeding drive mechanism 16, a second feeding drive mechanism 17, and a third feeding drive mechanism 18. The cutting assembly 9 includes a stacking cutter 901 that cooperates with the three feeding mechanisms.

The first motor 20 drives the drive rod 2102 to swing via the first synchronous belt assembly 2101. The swinging of the drive rod causes the transmission rod 2103 to swing. The transmission rod is connected to the corresponding paddle drive arm 27, that is, it drives the corresponding paddle drive arm 27 to drive the corresponding paddle lever to paddle or reset. The second feeding transmission assembly 23 includes a second synchronous belt assembly 2301 located between the second motor 22 and the paddle drive arm 27 of the second feeding mechanism 17.

The connecting rod assembly 1903 is entirely based on existing technology. The first motor 20 drives the cutter drive arm 1901, which in turn drives the connecting rod assembly 1903, causing the drive shaft 1902 to rotate and drive the cutter assembly 9 to slice. A cutter return spring is provided between the connecting rod assembly 1903 and the mounting base to drive the cutter to return to its original position.
