Detailed Description

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

As shown in fig. 1 to 5, 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, side plates 41 and a drive 5.

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, and the cloth moves relative to the blade 311 during the cutting process, although the cutting process may also adopt a form in which the blade 311 moves, which is only one example 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 may result in uneven cutting, the above-mentioned vibrating cutter 31 further includes a presser foot 32 for flattening the cloth, and the presser foot 32 may be arranged in different ways, for example, the presser foot 32 may be arranged 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.

When cutting, whole cutting assembly 3 also can reciprocate and adjust the interval relative to the cloth on workstation 1, its removal is realized through driver 5, in order to avoid whole cutting assembly 3's action to cause the interference to the sewing needle, foretell curb plate 41 and aircraft nose 2 relatively fixed and arrange in the lateral part of aircraft nose 2, leave installation space 40 between the curb plate 41 and the lateral wall board of aircraft nose 2, and driver 5 is then located in installation space 40, and its output is connected with cutting assembly 3, thereby drive cutting assembly 3 reciprocates relative to workstation 1. Specifically, a laterally extending connecting plate 42 is provided on the front side of the head 2, one end of the connecting plate 42 fixed to the head 2 is a connecting end, and the other end is a free end, and the side plate 41 is attached to the free end of the connecting plate 42 and extends downward.

The driver 5 in this embodiment is a cylinder mounted on the side plate 41, a vertically extending guide rail 43 is further disposed in the mounting space 40, a slider 44 is slidably constrained on the guide rail 43, the cutting assembly 3 is connected to the slider 44, and an output shaft of the cylinder is connected to the slider 44, specifically, the guide rail 43 is disposed on the cylinder and is adjacent to the machine head 2.

Furthermore, directional terms, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," "bottom," and the like, used in the description and claims of the present invention are used to describe various example structural portions and elements of the present invention, but are used herein for convenience of description only and are to be determined based on example orientations shown in the accompanying 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.
