Description

Technical Field

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

[0002] In sequin embroidery, a feeding device is used to transport sequins. A lever moves the sequins to the working position for slicing, and then the needle bar sews the embroidery. Existing feeding devices include a feeding base plate for transporting sequins, a feeding groove on the feeding base plate, and a fixed blade near the needle bar for cooperating with the slicing blade. The upper end of the feeding slot is equipped with a pressing mechanism for positioning gold sheets. The pressing mechanism includes a pressing spring and a mounting shaft for mounting the pressing spring. The mounting shaft is mounted on a fan-shaped mounting block, and the mounting block is located on a mounting base. For multi-gold sheet feeding mechanisms, especially those with three or more gold sheets, there are multiple stacked feeding structures. Each feeding structure includes a deflector, a transmission arm connected to the deflector, and a limiting rod that restricts the position of the deflector. The limiting rod is mounted on the mounting base. Therefore, the mounting base not only needs to leave space for the installation of the limiting rod, but also space for the movement of each deflector and transmission arm. This results in a small installation space for the fan-shaped mounting block of the pressing mechanism, making installation and disassembly inconvenient. Furthermore, the installation positions of the deflector, transmission arm, and limiting rod are also restricted, making the overall structure less compact and occupying more space. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a tablet pressing mechanism for a multi-plate feeding device. To adapt to space constraints, the tablet pressing mechanism is directly mounted on the corresponding feeding slot, facilitating installation and disassembly, freeing up more installation space on the mounting base, and making it easier to install other components. The overall structure is compact and occupies little space.

[0004] The technical solution adopted is as follows: A tablet pressing mechanism for a multi-plate feeding device includes a mounting base and at least three feeding mechanisms stacked sequentially on the mounting base. Each feeding mechanism includes a feeding base plate. Multiple feeding mechanisms are located above the bottom feeding mechanism, and at least one feeding mechanism has a pressing structure. The pressing structure includes a pressing spring that cooperates with the feeding base plate and a rotating shaft for mounting the pressing spring. The feeding base plate has a mounting block. The rotating shaft is rotatably mounted on the mounting block. The rotating shaft has a torsion spring that can drive the pressing spring to cooperate with the feeding base plate. One end of the torsion spring is located on the rotating shaft, and the other end is fixed to the mounting block. An adjustment structure for adjusting the spring pressure of the pressing spring is provided between the rotating shaft and the mounting block.

[0005] Furthermore, the rotating shaft is provided with a mounting sleeve, and one end of the torsion spring is fixed to the mounting sleeve.

[0006] Furthermore, the adjustment structure includes an adjustment block that can drive the rotating shaft to rotate, at least two positioning grooves or positioning holes provided on the mounting block and cooperating with the adjustment block, the adjustment block is provided with a through hole for the positioning pin to pass through, and the positioning pin passes through the through hole and cooperates with different positioning grooves or positioning holes.

[0007] Furthermore, there are three positioning grooves or positioning holes, which are distributed sequentially on the rotation path of the adjusting block.

[0008] Furthermore, the torsion spring is fixed to the mounting block by a pin.

[0009] Furthermore, the mounting sleeve is fixed to the rotating shaft by a fixing pin, and the fixing pin also fixes the torsion spring to the mounting sleeve.

[0010] Furthermore, the feeding plate is provided with a pressure plate, and the pressure plate is provided with a groove for accommodating the pressure spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a pressing mechanism for a multi-metal sheet feeding device, mainly used in multi-metal sheet feeding devices with three or more metal sheets. The pressing mechanism is mounted on the feeding base plate of the feeding mechanism, rather than on the mounting base of the feeding device, to accommodate space requirements and provide more installation space for other components of the feeding mechanism. The structure can be designed to be more compact and occupy less space. Furthermore, the pressing mechanism is located on the feeding base plate, close to the outer side, facilitating installation and disassembly. The pressing mechanism is equipped with a torsion spring that drives the pressing spring, and also has an adjustment structure to adjust the elastic force of the torsion spring.

Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments.

[0015] refer to Figure 1 , 2 3, 4, A pressing mechanism for a multi-plate feeding device includes a mounting base 1 and at least three feeding mechanisms 2 stacked sequentially on the mounting base. Each feeding mechanism 2 includes a feeding base plate 3. Multiple feeding mechanisms 2 are located above the bottom feeding mechanism. At least one feeding mechanism 2 is equipped with a pressing structure 4. The pressing structure 4 includes a pressing spring 401 that cooperates with the feeding base plate 3 and a rotating shaft 402 for mounting the pressing spring 401. The feeding base plate 3 is equipped with a mounting block 403. The rotating shaft is rotatably mounted on the mounting block 403. The rotating shaft 402 is equipped with a torsion spring 8 that can drive the pressing spring 201 to cooperate with the feeding base plate 3. One end of the torsion spring is located on the rotating shaft 402, and the other end is fixed to the mounting block 403. An adjustment structure 6 for adjusting the pressing spring pressure is provided between the rotating shaft 402 and the mounting block 403.

[0016] The torsion spring 8 is used to drive the pressure spring 401 to press the sheet. The torsion spring 8 provides elastic force to the rotating shaft. The rotation of the rotating shaft 402 can drive the pressure spring 401 to rotate. The sheet is located between the pressure spring 401 and the sheet feeding base plate 3. The pressure spring 401 and the sheet feeding base plate 3 cooperate to press the sheet.

[0017] The rotating shaft 402 is provided with a mounting sleeve 7, and one end of the torsion spring 8 is fixed to the mounting sleeve 7.

[0018] The adjustment structure 6 includes an adjustment block 601 that can drive the rotating shaft to rotate, and at least two positioning slots or positioning holes 602 on the mounting block that cooperate with the adjustment block 601. The adjustment block 601 has a through hole 9 for the positioning pin to pass through, and the positioning pin passes through the through hole and cooperates with different positioning slots or positioning holes 602. The adjustment structure 6 can adjust the spring force of the torsion spring and the position of the pressure spring 201 according to different needs. Placing the pressure structure 4 on the feeding base plate instead of on the mounting base not only facilitates the installation and disassembly of the pressure structure 4, but also leaves more space for the limit rod, the pawl rod on the feeding structure, and the transmission arm. The overall structure is compact and occupies less space.

[0019] The mounting sleeve 7 is also connected to the adjusting block 601. When the adjusting block 601 rotates, it drives the rotating shaft and the mounting sleeve 7 to rotate synchronously. By rotating the adjusting block 601, the elastic force of the torsion spring is adjusted, changing the distance between the pressure spring 201 and the feeding base plate. The positioning post cooperates with the positioning groove or positioning hole 602 to fix the position of the adjusting block 601 to adapt to different needs. For example, when it is necessary to replace the sheet and re-thread it, the pressure spring 201 needs to be driven to rise to leave enough space for threading or replacing the sheet; when it is necessary to press the sheet, the pressure spring 201 needs to press down to press the sheet. Preferably, there are three positioning grooves or positioning holes 602, which are distributed sequentially on the rotation path of the adjusting block 601.

[0020] The torsion spring 8 is fixed to the mounting block 403 by a pin 5.

[0021] The mounting sleeve 7 is fixed to the rotating shaft 402 by a fixing pin, which also fixes the torsion spring 8 to the mounting sleeve. Of course, the fixing pin can also fix the mounting sleeve alone, and the torsion spring 8 can be fixed to the mounting sleeve 7 by other fixing methods or the fixing pin.

[0022] The feeding base plate 3 is provided with a pressure plate 10, and the pressure plate 10 is provided with a groove 11 for accommodating the pressure spring. The feeding base plate is also provided with a sliding groove for the pusher rod to push the plate. The pressure plate 10 is provided with a feeding groove and a through hole for the gold sheet to pass through. The gold sheet passes through the through hole and is placed in the feeding groove. The pusher rod pushes the gold sheet to feed it. This structure can refer to the prior art.

[0023] The feeding device used in this embodiment is a three-sheet feeding device, but it can also be used for multi-sheet feeding devices with more than three sheets. In this embodiment, the feeding mechanism 2 has three parts, namely a first feeding mechanism 201, a second feeding mechanism 202, and a third feeding mechanism 203 arranged vertically. The tablet pressing structure 4 is provided on the first feeding mechanism 201 and the second feeding mechanism 202. The third feeding mechanism 203 is provided with a tablet pressing assembly, which is a traditional tablet pressing assembly. This structure can be directly referred to in the prior art.
