Description

Technical Field

[0001] This invention relates to a multi-gold sheet device and an embroidery machine using the device. Background Technology

[0002] The gold sheet embroidery device requires cutting the continuously fed gold sheets one by one using a cutter. Multi-sheet devices can output multiple sheets of various sizes and with higher output efficiency. Current multi-sheet devices typically include cutting blades that mate with corresponding feed slots for multiple gold sheets, and a cutter bar connecting the corresponding blades. The feed slots, as needed, are driven by a drive mechanism that engages with the needle bar, and the drive mechanism in turn moves the cutter bar to cut the corresponding gold sheet. To ensure each blade can cut the gold sheet accurately, the blades are usually thin and easily broken. Cutting any gold sheet requires the entire cutter bar to move, driving all the blades to cut. This structure is complex, and the installation and adjustment of numerous blades is difficult. Summary of the Invention

[0007] As a further improvement, the cutter includes a cutting edge and a drive arm. The cutter is rotatably mounted on the cutter holder, and the power transmission structure is movably connected to the corresponding part of the drive arm.

[0008] As a further improvement, the power input device is a slice motor, pneumatic, hydraulic, or electromagnetic actuator.

[0009] As a further improvement, the power transmission structure includes a rocker arm mounted on the slicing motor shaft and a connecting rod movably connected at one end to the rocker arm, the other end of which is movably connected to a corresponding part of the slicing drive arm to drive the slicing blade.

[0010] As a further improvement, the cutter is provided with an elastic preload that cooperates with the corresponding feeder located at the feeding station, and the cutter shaft is axially elastically movable and is mounted on the cutter holder to cooperate with the corresponding feeder located at the feeding station.

[0011] As a further improvement, the at least one set of wafer feeders includes upper and lower wafer feeders for stacking wafers.

[0012] As a further improvement, the upper and lower feeders each include corresponding upper and lower levers, upper and lower slots, and lever drivers. The upper lever of the upper feeder of each group of feeders is sleeved on an upper shaft, and the lower lever of the lower feeder of each group of feeders is sleeved on a lower shaft. The lever driver includes upper and lower lever motors, and the upper and lower lever motors are respectively connected to upper and lower connecting rod assemblies. One end of the upper and lower shafts is fixed to the mounting plate of the multi-plate device. The upper and lower lever motors are fixed to the mounting plate. The upper and lower connecting rod assemblies selectively drive the upper and lower levers of any group of feeders. The upper and lower connecting rod assemblies selectively drive the upper and lower levers of the corresponding group of feeders as the plate changing driver switches the corresponding group of feeders.

[0013] As a further improvement, the cutter is an upper and lower stacking cutter corresponding to the upper and lower feeders.

[0014] As a further improvement, the feeding mechanism is also provided with a feeding mechanism that drives the feeding mechanism to feed towards or back to an appropriate position according to the size of the upper or / and lower gold sheet. The appropriate position is the position where the upper and lower feeders can feed the gold sheet to the normal embroidery piece below the embroidery needle.

[0015] As a further improvement, the feeding mechanism includes a connecting feeding mechanism and a support body, a power-driven lead screw or ball screw structure, a drive linkage structure, a matching gear and rack structure or a matching pulley and synchronous belt structure, or a linear motor, pneumatic or hydraulic rod.

[0016] As a further improvement, a lifting mechanism is also included, which includes an upper section fixedly installed on the machine head, a lower section consisting of a multi-piece device and a support body, and a lifter connecting the upper and lower sections. The lifter drives the lower section to move downwards at the needle engagement point and drives the lower section to lift away from the needle engagement point.

[0017] As a further improvement, a controller is also included.

[0018] An embroidery machine equipped with a multi-gold sheet device of any one or a combination of the above schemes, wherein the embroidery machine is provided with at least one machine head, and a multi-gold sheet device is installed on one side, the front side, or / and both sides of the at least one machine head.

[0019] The aforementioned embroidery machine has at least one side of the machine head equipped with the aforementioned multi-gold sequin device, and the other side equipped with a beaded embroidery device.

[0020] This invention relates to a multi-sheet gold sheet device and an embroidery machine using the device. Compared with existing technologies, the cutting blade assembly is configured as a single-cutting blade. This blade is positioned at the sheet feeding station and works in conjunction with the sheet feeder located at that station to slice the gold sheets. The blade includes a blade holder for mounting and positioning the blade and a slicing driver for driving the blade to slice the gold sheets. The advantages are that the single-cutting blade is easy to install, adjust, and maintain; the blade can be relatively heavy and robust, extending its service life; and when slicing gold sheets from multiple sheet feeders with the single-cutting blade, the sliced ​​gold sheets produce a beautiful and neat appearance. This invention's blade only requires rotating the slicer, resulting in high transmission efficiency, a simple transmission structure, and low manufacturing cost, thus possessing extremely high manufacturing and practical value.

[0021] Furthermore, the stacking sheet feeder of the present invention includes upper and lower sheet feeders for stacking. The sheet feeding mechanism is also equipped with a feeding mechanism that drives the sheet feeding mechanism to advance or retreat to an appropriate position according to the size of the upper and / or lower gold sheet. Thus, when two sheets need to be stacked and embroidered on one needle position, the feeding mechanism advances or retreats to an appropriate position according to the size of the upper gold sheet. The pawl motor of the sheet feeding mechanism drives the upper sheet feeder to deliver the upper gold sheet to the embroidery position below the needle. While the needle is embroidering the upper gold sheet, the slicing blade of the cutting mechanism cuts the upper gold sheet, completing the stacking of one upper and lower gold sheet. The upper and lower gold sheets are both processed independently by the feeding mechanism driving the sheet feeding mechanism, so the size of the upper and lower sheets is no longer limited. The feeding mechanism can precisely control the feeding and cutting of each gold sheet according to its size, avoiding the accumulation of errors in the prior art, and resulting in a beautiful stack.

[0022] This invention's device can be widely applied to existing embroidery machines and can be installed on the machine head in conjunction with other functional devices such as bead embroidery devices. This invention's device offers high efficiency in slicing embroidery pieces, and the cutter is easy to maintain and repair. Attached Figure Description
