Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 7, it is a preferred embodiment of the present invention.

In this embodiment, the pattern machine comprises a table 1, a head 2, a cutting assembly 3 and a suction structure 4.

The machine head 2 is arranged on the workbench 1 and is provided with a sewing needle head 20, and the cloth conveyed to the machine head 2 stays at the position of the front side of the machine head 2 after being processed by the sewing needle head 20. The cutting assembly 3 is disposed on the handpiece 2 and arranged at the front side of the needle, and comprises a vibrating cutter 31, and a blade 311 extending vertically is arranged at the bottom of the vibrating cutter 31. Since the sewing process requires moving the cloth, the clamping jaw 8 is further disposed on the worktable 1, and the cloth can move on the worktable 1 along the X direction and the Y direction under the driving of the clamping jaw 8, and the subsequent cutting action is also realized based on the movement of the clamping jaw 8 to the cloth, that is, the position of the blade 311 in the cutting assembly 3 relative to the worktable 1 is not changed (the blade 311 itself vibrates, as will be described later), and the cloth moves relative to the blade 311, although the cutting process may also adopt a form of moving the blade 311, which is only exemplified in this embodiment. In addition, since the use of the clamping jaws 8 to move the cloth belongs to the conventional technology, the detailed description is omitted.

The vibration cutter 31 is composed of two parts, one is a vibrator 312, i.e., a vibration source, and the other is a blade 311, wherein a support frame 315 is further provided around the vibrator 312, and the vibrator 312 is mounted on the head 2 through the support frame 315. The blade 311 is connected to the output end of the vibrator 312 and can move up and down under the driving of the vibrator 312, and under the vibration action of the vibrator 312, the blade 311 moves up and down at a higher frequency, thereby realizing cutting. Since the cutting part of the cloth may be pulled by the up-and-down movement and the translation of the cloth driven by the clamping jaw 8 during the cutting, which results in uneven cutting, the vibrating cutter 31 further includes a presser foot 32 for flattening the cloth, and the presser foot 32 may be disposed in different manners, for example, the presser foot 32 may be disposed on at least one of the two sides of the cutting direction of the blade 311. In this embodiment, the design form of the presser feet 32 on both sides of the blade 311 is adopted to ensure uniform cutting of the cloth, that is, there are two presser feet 32, the two presser feet 32 extend in the same direction and are arranged side by side, and a gap 320 for the blade 311 to pass through is formed between the two presser feet 32.

In order to ensure the installation of the presser foot 32, the bottom of the vibrating cutter 31 is provided with a vertically extending connecting piece 313 at one side adjacent to the blade 311, and the presser foot 32 is formed by extending laterally from the lower end of the connecting piece 313. Specifically, the vibrating cutter 31 has a mounting seat 314 at the bottom thereof, and the connecting piece 313 is mounted on the outer edge of the mounting seat 314, that is, the mounting seat 314 in the present embodiment is annular and arranged on the periphery of the blade 311. In order to prevent the presser foot 32 from damaging the cloth, a step 316 for buffering the impact force of the presser foot 32 is formed at the middle of the connecting piece 313 by bending in the direction of the blade 311.

During cutting, the whole cutting assembly 3 can also move up and down to adjust the distance between the cloth and the workbench 1, the movement is realized through the driver 5, the cloth can be taken up by the up and down movement of the whole cutting assembly 3 and the movement of the blade 311 in the vibration cutter 31, and therefore, except for the structure of the presser foot 32, the workbench 1 in the embodiment is provided with the flow guide holes 10 at the position corresponding to the vibration cutter 31. The flow guide holes 10 actually play two roles, one is air guide, namely the air suction structure 4 is provided with an air suction channel which is communicated with the flow guide holes 10, and the cloth can be firmly adsorbed on the table top of the workbench 1 through the negative pressure effect of the air suction structure 4, so that the cloth is prevented from being brought up. The air suction structure 4 specifically comprises an air suction pump 41 and an air suction pipe 42, the air suction pump 41 is communicated with the flow guide hole 10 through the air suction pipe 42 to form an air suction channel, and an adapter 43 for connecting the air suction pipe 42 is arranged at the bottom of the workbench 1 at a position corresponding to the flow guide hole 10. The second function of the diversion hole 10 is to avoid damaging the table top, when cutting, the output end of the vibration cutter 31 can extend into the diversion hole 10 to avoid the diversion hole 10 from being formed by downward sinking of the upper surface of the workbench 1, the flexible piece 11 is arranged in the diversion hole 10, and the upper edge of the diversion hole 10 extends inwards in the circumferential direction to have a blocking edge for supporting the flexible piece 11.

Furthermore, directional terms such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", and the like are used in the description and claims of the present invention to describe various example structural parts and elements of the present invention, but these terms are used herein only for convenience of description and are determined based on example orientations shown in the drawings. Because the disclosed embodiments may be arranged in different orientations, these directional terms are for illustrative purposes only and should not be construed as limiting, and for example, "upper" and "lower" are not necessarily limited to orientations opposite or consistent with the direction of gravity.
