Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 4, 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 drive mechanism 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 table 1, and the cloth can move on the table 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 table 1 is not changed during the cutting process, and the cloth moves relative to the blade 311, 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 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 bottom of the vibration cutter 31 has a mounting seat 314, 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.

The whole cutting assembly 3 rotates to adjust the cutting angle of the blade 311, and in this embodiment, the power output end of the driving mechanism 4 is in driving connection with the cutting assembly 3, so as to drive the blade 311 and the presser foot 32 to rotate synchronously. The driving mechanism 4 is a motor provided in front of the head 2 and arranged side by side with the vibrator 312, and an output shaft of the motor extends vertically. In order to realize transmission, an output shaft of the motor is provided with a first transmission wheel 5, a second transmission wheel 6 is arranged at the top of the vibrator 312, and the vibrator 312 is linked with the motor through a transmission belt 7 which is sequentially wound on the first transmission wheel 5 and the second transmission wheel 6 and can drive the blade 311 and the presser foot 32 to synchronously rotate.

Also, directional terms, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," "bottom," and the like, may be used in the description and claims to describe various example structural portions and elements of the utility model, but are used herein for convenience of description only and are determined based on the example orientations shown in the figures. Because the disclosed embodiments of the present invention may be oriented in different directions, the directional terms are used for descriptive purposes and are not to be construed as limiting, e.g., "upper" and "lower" are not necessarily limited to directions opposite to or coincident with the direction of gravity.
