Detailed Description

The following further description is made with reference to the embodiments shown in the drawings.

In the high-speed carving device of the computer embroidery machine shown in the attached drawings, the bottom end of a lifting motor base 5 is fixed on a guide rail bracket 14, the guide rail bracket transversely extends to a vertical connecting block 27 and is fixed with the vertical connecting block (fixed through a fastener), and the vertical connecting block is fixed with a needle bar frame 1 (fixed through a fastener); on the needle bar carrier are positioned a number of needle bars 27 (in the figure, the needles at the bottom end of each needle bar are removed) driven by a needle bar drive mechanism (prior art, omitted from the figures).

The lifting guide rail pair comprises a guide rail 9 and a slide block 8 in sliding fit with the guide rail; the guide rail 9 is fixed on one side of the lifting motor base facing the needle bar frame; the rotary guide rod seat 10 is fixedly connected with the sliding block, the top matching end 18-1 of the rotary guide rod can axially slide and can also be rotationally positioned in the rotary guide rod seat through a sliding bearing (preferably a linear bearing), the middle matching end 18-2 of the rotary guide rod can also axially slide and can also be rotationally positioned in the guide rail bracket through a positioning sleeve 15 (the middle matching end 18-2 and the positioning sleeve 15 form another sliding bearing), the outer circumferential surface of the positioning sleeve is provided with a groove surrounding the circumference, and after the positioning sleeve is embedded into a positioning hole on the guide rail bracket, a pin passes through the hole wall of the positioning hole and then extends into the groove, so that the positioning sleeve can only rotate but cannot axially move). The bottom of the rotating guide rod is provided with a graver chuck 21 for clamping a graver 22 (as can be seen from the figure, the graver chuck is in a round tube shape, a plurality of screw holes penetrating through the tube wall are radially formed, and the graver inserted into the tube hole is pressed and fixed by screws screwed into the screw holes).

The high-speed motor 7 is fixed with the rotary guide rod seat through the high-speed motor seat 7-1, so that the high-speed motor and the rotary guide rod seat can vertically slide along with the sliding block. The high-speed motor drives the rotary guide rod to carry out carving and cutting operation through a vibrating structure, and the vibrating structure comprises an I-shaped frame 18-3 arranged at the top of the lifting guide rod and an eccentric rod 19 transversely embedded between two baffles of the I-shaped frame; the eccentric rod is fixedly connected with a high-speed motor shaft, and the eccentric amount of the eccentric rod is 0.2-0.7mm (preferably 0.5 mm); the speed of the high speed motor is preferably greater than 1 ten thousand revolutions per minute.

The device is also provided with a direction adjusting mechanism for adjusting the carving and cutting direction of the rotating guide rod. In the direction adjustment mechanism: the driven synchronizing wheel 16 is matched with the lifting guide rod in a penetrating way through a D-shaped hole structure (the cross section of the middle part of the lifting guide rod is D-shaped, a shaft hole on the driven synchronizing wheel is a D-shaped hole matched with the lifting guide rod, the driven synchronizing wheel can be sleeved in the middle part of the lifting guide rod in a penetrating way, the driven synchronizing wheel and the lifting guide rod can axially slide but only synchronously rotate, and the end surface of the top end of the synchronizing wheel is fixedly connected with the end surface of the bottom end of the positioning sleeve, so that the synchronous wheel is axially. The direction motor 11 is fixed on the guide rail bracket through a direction motor base, a driving synchronous wheel 12 is fixed on a motor shaft of the direction motor 11, and a synchronous belt 13 is matched with the driven synchronous wheel and the driving synchronous wheel. Obviously, the direction motor starts to drive the lifting guide rod to rotate, so that the carving angle of the tool tip of the carving knife is adjusted.

The high-speed carving device is also provided with a lifting mechanism; the lifting mechanism comprises a lifting motor 2 fixed on a lifting motor base 5, a crank 3 fixed on the shaft of the lifting motor and a connecting rod 4 (the connecting rod is hinged with a hinging lug 6 fixed on a rotating guide rod base) with two ends respectively hinged with the crank and the rotating guide rod base. The lifting motor is started to drive the rotating guide rod and the high-speed motor to vertically move. As can be seen from the figure: enough space is reserved in the lifting motor base, and the high-speed motor in the space is allowed to move up and down without interference.

A material pressing ring 23 is further arranged in the circumferential direction of the carving knife; the material pressing ring is a circular ring with the inner diameter larger than that of the carving knife and is fixed at the bottom ends of the three telescopic rods 20, and the top ends of the three telescopic rods are fixedly connected with the guide rail support through the fixing sleeve 17. The telescopic rod is provided with a spring (a conventional structure, and the spring is omitted in the figure) so that the material pressing ring is abutted against the material to be carved and cut with certain pressure. When the material carving machine works, a carved material is abutted against the tensioning ring 26 on the computer embroidery machine bedplate 25 (the tensioning ring protrudes out of the embroidery machine bedplate by 4-8mm) and is tensioned and flattened, and the material pressing ring is abutted against the carved material, so that the carving knife can accurately and effectively carve and cut the carved material, and the carving knife can not directly touch the embroidery machine bedplate (thereby avoiding the damage of the carving knife).
