Description

Technical Field

[0001] The utility model relates to the technical field of rope embroidery, in particular to a rope cutting device for rope embroidery. Background Art

[0002] When embroidery machines are used for multi-color rope embroidery, each time a color is completed, the rope must be cut before the next color can be embroidered. Currently, multi-color rope embroidery machines are available in two configurations: single-needle and multi-needle. However, due to the limitations of the machine's rope embroidery principles, most machines with these configurations still rely on manual rope cutting, requiring dedicated personnel to perform this operation. This not only poses safety risks but also requires a certain level of operator proficiency. Furthermore, the efficiency of rope cutting directly impacts the machine's operating efficiency. Therefore, rope cutting devices have been designed to replace manual rope cutting. These mechanisms must move to the vicinity of the needle bar to hook and cut the rope. Existing rope cutting mechanisms require a complex path to reach their working position, requiring not only a drive motor for rope cutting but also a separate motor to drive the entire rope cutting mechanism. This complex path not only increases the load on the motor but also increases costs. Especially for multi-color rope embroidery, the rope cutting mechanism must be driven to the lower end of the corresponding rope feed ring to cut the rope. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and cannot be understood as limitations on the present invention.

[0022] The "front" refers to the direction in which the rope cutting mechanism moves toward the rope cutting position; the "back" refers to the direction in which the rope cutting mechanism moves away from the rope cutting position.

[0023] refer to Figure 1-6 A rope cutting device for rope embroidery includes at least one rope embroidery component 18, a rope cutting mechanism 1, and a connecting plate 3 connecting an external mechanism 2 and the rope cutting mechanism 1. The connecting plate 3 is provided with a first sliding structure 4 for the rope cutting mechanism 1 to slide up and down relative to the external mechanism 2 for working or retreating, and a corresponding first sliding drive structure 5. The connecting plate 3 is also provided with a second sliding structure 6 for the rope cutting mechanism 1 to slide to the rope cutting position and a corresponding second sliding drive structure 7. The rope cutting mechanism 1 includes a rope cutting structure 8 and a driving structure 9 for driving the rope cutting structure 8 to perform the rope cutting action.

[0024] It also includes a first mounting plate 10 for mounting the first sliding structure 4 and a second mounting plate 11 for mounting the second sliding structure 6 . The first mounting plate 10 is connected to the connecting plate 3 .

[0025] The first sliding structure 4 includes a first sliding rail 401 provided on the first mounting plate 10 and a first slider 402 cooperating with the first sliding rail; the second sliding structure 6 includes a second sliding rail 601 provided on the second mounting plate 11 and a second slider 602 cooperating with the second sliding rail.

[0026] The device further includes a lifting and fixing plate 12 connected to the first slider and the second mounting plate 11. The first sliding drive structure 5 is a first cylinder. The first cylinder shaft 501 extending from the first cylinder is mounted on the first mounting plate 10, and the first cylinder body 502 of the first cylinder is mounted on the lifting and fixing plate 12. When the first cylinder is activated, the first cylinder shaft and the first cylinder body move relative to each other, that is, the first slider 402 slides up and down on the first slide rail 401, driving the lifting and fixing plate 12 to move up and down. Since the lifting and fixing plate 12 is connected to the second mounting plate 11, and one side of the second mounting plate 11 is connected to the rope cutting mechanism 1, the lifting and fixing plate 12 can drive the entire rope cutting mechanism 1 to move up and down.

[0027] The device further includes front and rear fixed plates 13 connected to the second slider and the rope-cutting mechanism 8. The second sliding drive structure 7 is a second cylinder. A second cylinder shaft 701 extending from the second cylinder is disposed on the front and rear fixed plates 13. The second cylinder body 702 of the second cylinder is disposed on the lifting fixed plate 12. When the second cylinder is activated, the second cylinder shaft and the second cylinder body move relative to each other, that is, the second slider 602 slides back and forth on the second slide rail 601, driving the front and rear fixed plates 13 to move back and forth. Since the front and rear fixed plates 13 are connected to the rope-cutting mechanism 1, they can drive the entire rope-cutting mechanism 1 to move back and forth.

[0028] Compared with driving motors, using cylinder drives has lower costs and simpler structures.

[0029] The first sliding structure 4 is provided for the up-and-down sliding of the rope-cutting mechanism 1, and the second sliding structure 6 is provided for the forward and backward sliding of the rope-cutting mechanism 1. The first sliding drive structure 5 drives the rope-cutting mechanism 1 to slide downward, and then the second sliding drive structure 7 drives the rope-cutting mechanism 1 to move to the rope-cutting position, and the drive structure 9 drives the rope-cutting mechanism 8 to cut the rope. After the rope-cutting action is completed, the second sliding drive structure 7 drives the rope-cutting mechanism 1 to return to its initial position, and the first sliding drive structure 5 drives the entire mechanism to move upward to avoid affecting the operation of the needle near the machine head.

[0030] The rope shearing structure 8 includes a fixed knife 16 and a movable knife 17 hinged to the fixed knife. The fixed knife is fixed on the motor mounting plate 902 provided on the driving structure.

[0031] The drive structure 9 includes a drive motor 901, a motor mounting plate 902, a drive arm 903 mounted on the output shaft of the drive motor to drive the movable blade 17, and a transmission rod 904 connecting the drive arm to one end of the movable blade 17. The drive motor 901 drives the drive arm 903 to swing, which in turn drives the movable blade 17 via the transmission rod 904. The movable blade 17 moves, cooperating with the fixed blade 16 to cut the rope. The motor mounting plate 902 is provided with a slot for the drive rod 904 to swing, which limits the range of the drive rod 904's swing. A return spring is provided between the drive rod 904 and the motor mounting plate 902. The drive motor 901 drives the drive arm 903 to cause the drive rod 904 to swing unidirectionally. The return spring then resets the drive rod 904, thereby resetting the movable blade 17.

[0032] The cord embroidery assembly 18 includes a cord feeding ring 14 for feeding the cord, with a cord clamping structure 15 located on one side of the cord feeding ring 14. The cord feeding ring 14 rotates to feed the cord, and the needle on the machine head lowers the needle to embroider the cord onto the embroidery cloth. The cord clamping structure 15 on one side of the cord feeding ring 14 can utilize existing technology. In this embodiment, the cord clamping structure 15 includes an upper pressing plate and a lower pressing plate. When the lower pressing plate is not in operation, it is positioned away from the upper pressing plate. When the cord passes the lower end of the upper pressing plate, if cord clamping is required, the lower pressing plate is driven toward the upper pressing plate. The upper and lower pressing plates cooperate to clamp the cord. At this point, the first and second sliding drive structures drive the scissors (i.e., the hinged movable and fixed knives) of the cord cutting mechanism 1 to the corresponding cord cutting position of the cord embroidery assembly to perform the cord cutting operation. After the cord cutting is completed, the cord cutting mechanism 1 is driven to retreat away from the cord embroidery assembly. The purpose of the cord clamping is to prevent the embroidery cord from being instantly rebounded by the tension of the cord feeding device.

[0033] The utility model can be used for single-color or multi-color rope embroidery. In this embodiment, multi-color rope embroidery is used, that is, multiple rope embroidery components 18 are provided. A driver can be provided outside the rope embroidery components 18 to drive the rope embroidery components 18 that need to be cut into the rope cutting position, and the rope cutting mechanism can cut the rope. The driver can completely adopt existing technology.

[0034] This utility model not only drives the rope cutting mechanism 1 up and down for retraction, but also drives it to the cutting position for rope cutting. When rope cutting is not required, the rope cutting mechanism 1 can be driven upward for retraction without affecting the operation of other components. This rope cutting device replaces manual rope cutting, saving time and improving efficiency. The cylinder-driven sliding mechanism occupies a small space and is low-cost. With only up and down, forward and backward movements, the motion trajectory is simple and uncomplicated, eliminating any wasted power.

[0035] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
