[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that, for the sake of description, only the parts related to the utility model are shown in the drawings.

[0029] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0030] At least refer to Figures 1 - 4 As shown, an example of the present utility model provides a head of a computerized embroidery machine. The head includes a needle bar holder 10, a machine shell 20, and a hollowing device 30. The hollowing device 30 is located on the left or right side of the needle bar holder 10. Among them, the hollowing device 30 can move independently, and independent hollowing can be performed at any needle position, making full use of all needle positions to achieve embroidery with richer colors. The independent hollowing can parametrically adjust the hollowing depth, change the hollowing size, and expand the application of hollowing.

[0031] As Figures 1 - 3 shown, the hollowing device 30 includes: a first rod 31, a second rod 32, a connecting piece 33, a driving block 34, a hollowing cutter 35, and a hollowing driving mechanism 38.

[0032] Both the first rod 31 and the second rod 32 are located on the right side of the needle bar holder 10. The first rod 31 is arranged in the vertical direction. The upper end of the first rod 31 is connected to the driving block 34, and the driving part 341 is provided on the driving block 34. The second rod 32 is arranged in the vertical direction, and the lower end of the second rod 32 is connected to the hollowing cutter 35. The connecting piece 33 connects the first rod 31 and the second rod 32.

[0033] The hollowing driving mechanism 38 is located above the needle bar holder 10. The hollowing driving mechanism 38 cooperates with the driving part 341 to make the first rod 31 reciprocate in the vertical direction.

[0034] Among them, as Figure 1 or Figure 2As shown in the figure, the hole carving drive mechanism 38 includes a hole carving drive shaft 381, a drive sleeve 382, and a drive swing rod 383. The hole carving drive shaft 381 is arranged in the left-right direction, and the length extension direction of the hole carving drive shaft 381 is parallel to the length extension direction of the beam of the computer embroidery machine.

[0035] The drive sleeve 382 is sleeved on the hole carving drive shaft 381, and one end of the drive swing rod 383 is fixedly connected to the drive sleeve 382. A rotating member (not labeled) is provided at the other end of the drive swing rod 383, and the rotating member can be a bearing or a wheel. The rotating member is arranged in the groove of the drive block 34, and the groove is in rolling contact with the rotating member. Of course, it can be understood that the other end of the drive swing rod 383 and the groove of the drive block 34 can be in sliding contact.

[0036] The hole carving drive shaft 381 rotates by a preset angle, so that the end of the drive swing rod 383 provided with the rotating member swings around the hole carving drive shaft 381, and the swing track of the end of the drive swing rod 383 provided with the rotating member is an arc in the up-down direction. Since the rotating member is in rolling contact with the groove of the drive block 34, the rotating member makes the first rod 31 reciprocate in the vertical direction, and then the second rod 32 can reciprocate in the vertical direction, so that the hole carving knife 35 can punch holes in the fabric.

[0037] The rolling contact between the end of the drive swing rod 383 provided with the rotating member and the groove of the drive block 34 can reduce the friction force between the end of the drive swing rod 383 provided with the rotating member and the groove of the drive block 34, which helps to inhibit the wear of the end of the drive swing rod 383 provided with the rotating member or the drive block 34, and extends the service life of the drive swing rod 383 or the drive block 34.

[0038] In practical applications, in addition to driving the drive block 34 to move in the vertical direction, the end of the drive swing rod 383 provided with the rotating member also has movement in the front-back or left-right direction, which is not conducive to the movement of the first rod 31 in the vertical direction, and further affects the movement of the second rod 32 in the vertical direction.

[0039] Based on this, the length of the second rod 32 in this application is half of the length of the first rod 31, or the length of the second rod 32 is less than half of the length of the first rod 31. Since the hole carving knife 35 is connected to the lower end of the second rod 32, shortening the length of the second rod 32 can reduce the center of gravity of the second rod 32, which helps to inhibit the movement of the second rod 32 in the front-back or left-right direction, so that the second rod 32 can move stably in the vertical direction.

[0040] As an implementable manner, the hole carving device 30 further includes a guide member 37, and the guide member 37 can be fixed on the outer surface of the machine shell 20 of the machine head.

[0041] The guiding member 37 is provided with a first guiding portion 371 and a second guiding portion 372. The first guiding portion 371 is in guiding cooperation with the first rod member 31 to limit the freedom degree of the first rod member 31 in the horizontal direction; and / or, the second guiding portion 372 is in guiding cooperation with the second rod member 32 to limit the freedom degree of the second rod member 32 in the horizontal direction. This avoids the jitter of the first rod member 31 and the second rod member 32, and helps the hole carving knife 35 to stably punch holes in the fabric.

[0042] As Figure 3 shown, the first guiding portion 371 of the guiding member 37 is a through hole, the first rod member 31 passes through the first guiding portion 371, and the first guiding portion 371 enables the first rod member 31 to move only in the vertical direction. The second guiding portion 372 of the guiding member 37 is a through hole, the second rod member 32 passes through the second guiding portion 372, and the second guiding portion 372 enables the second rod member 32 to move only in the vertical direction.

[0043] As an implementable mode, as Figure 1 or Figure 2 shown, a first rod guiding member 41 and a second rod guiding member 42 are further connected to the outer surface of the machine housing 20.

[0044] The first rod guiding member 41 is provided with a first guiding hole (not labeled), the first guiding hole is in guiding cooperation with the first rod member 31 to further limit the freedom degree of the first rod member 31 in the horizontal direction; the second rod guiding member 42 is provided with a second guiding hole (not labeled), the second guiding hole is in guiding cooperation with the second rod member 32 to further limit the freedom degree of the second rod member 32 in the horizontal direction. This further avoids the jitter of the first rod member 31 and the second rod member 32, and further enables the hole carving knife 35 to stably punch holes in the fabric.

[0045] As an implementable mode, the hole carving device 30 further includes a presser foot 36.

[0046] As Figure 1 or Figure 2 shown, the presser foot 36 is connected to the lower end of the second rod member 32. A third guiding portion 373 for guiding cooperation with the presser foot 36 is further provided on the guiding member 37, and the third guiding portion 373 guides the presser foot 36 to move in the vertical direction and limits the freedom degree of the presser foot 36 in the left - right direction.

[0047] As an implementable mode, a hole carving knife shielding member 50 is connected to the left side or the right side of the needle bar holder 10.

[0048] As Figure 4As shown in the figure, a carving hole cutter shielding member 50 is connected to the right side of the needle bar holder 10, and the carving hole cutter shielding member 50 is arranged near the bottom of the needle bar holder 10. The carving hole cutter shielding member 50 can shield the front of the carving hole cutter 35, preventing the operator from coming into contact with the carving hole cutter 35 and avoiding accidental cutting of the operator by the carving hole cutter 35.

[0049] Of course, it can be understood that when the carving hole cutter 35 punches holes in the fabric, the needle bar holder 10 can move to the front of the carving hole cutter 35 to shield the carving hole cutter 35.

[0050] This embodiment also provides a computerized embroidery machine, including a machine head having the above-mentioned carving hole device 30. This computerized embroidery machine has the following advantages:

[0051] The carving hole device 30 can move independently, and independent carving holes can be performed at any needle position, making full use of all needle positions to achieve embroidery with richer colors. The independent carving holes can be adjusted parametrically for the carving depth, change the carving hole size, and expand the application of carving holes.
