[0037] See also Figure 6 In the color-changing mechanism 107, a color-changing rod bracket 71 is fixed on the lifting guide rail fixing plate 21 on the ironing machine head 101, and a color-changing rod 72 is passed through the middle. The color-changing rod bracket 71 can hold the color-changing rod 72 and will not move up and down due to the lifting and lowering of the punch rod frame 103. Notches are opened on the left and right sides of the upper end of the punch rod frame 103, and a color-changing slot plate 74 is installed on the outside. The color-changing rod clamp ring 73 is used to lock the color-changing rod 72 on the outside of the color-changing slot plate 74. A sliding gap is left at the connection between the rod clamp ring 73 and the color-changing slot plate 74, which can make the punch rod frame 103 lift up and down. For this reason, the punch rod frame 103 can change colors left and right by pulling the color-changing rod 72 left and right.

[0038] See also Figure 7 and Figure 8The punching mechanism is installed on the main shaft 11 in the middle of the ironing machine head 101, the eccentric cam 12 on the main shaft 11, and the three-eye connecting rod 13 connected to the eccentric cam. The clutch driving block 15 is connected through the small connecting rod 14, and the guide rod 16 guides the lifting and lowering of the clutch driving block 15; it also includes a punch rod 31 installed on the punch rod frame 103, a punch needle 42 that contacts the punch rod 31, and a punch die 41 that fits with the punch needle 42. A driving head 32 that can be clutched and mounted on the punch rod 31 is installed. A clutch component that can clutch and engage with the driving head 32 is provided on the side of the clutch driving block 15. The clutch component is a jumping motor 17 and a jumping contact 18. The eccentric cam 12 drives the clutch drive block 15 to reciprocate up and down along the guide rod 16. When the punch rod frame 103 is in the lower position, the drive head 32 is within the movement stroke of the clutch drive block 15. The clutch drive block 15 drives the drive head 32, and the drive head 32 clamps the punch rod 31. The punch rod 31 contacts the punch needle 42 and reciprocates up and down in the die 41 to punch out the forming wafer 87. The forming wafer 87 contacts the embroidery cloth under the push of the punch needle 42, and contacts the top surface of the ultrasonic transducer 905 of the ultrasonic component 109. Under the action of the ultrasonic transducer 905, the forming wafer 87 is bonded to the embroidery cloth to form an embroidery product. The clutch member can clutch the drive head 32 to realize the skipping needle function, and the punch rod frame 103 can also be lifted and lowered by the motor lifting mechanism 105 after the clutch drive head 32.

[0039] See also Figure 8 The wafer of the punching mechanism is a wafer plate 81 clamped on the wafer holder 108. The wafer comes out of the wafer plate 81 and passes through the upper film slot 83. The wafer is clamped by the front film clamp 85, and then passes through the lower film slot 84. After passing through the lower film slot 84, it passes through the die 41, and then the wafer is clamped by the rear film clamp 86; after coming out of the rear film clamp 86, it goes to the rear pull-up mechanism. Under the pull of the pull-up mechanism, the punch rod 31 resists the punch needle 42 and reciprocates up and down in the die 41, punching the wafer into the required shape set by the die 41. When the wafer is about to be punched out, the wafer passes below the upper film slot 83. There is no wafer in the upper film slot 83, and the photoelectric sensor 27 at the back cannot receive the reflected light signal fed back by the wafer. The photoelectric sensor 27 will send a signal to the main control computer, and the main control computer will stop the machine and display a red light prompt on the control panel of the corresponding machine head, prompting the worker to replace the new wafer plate 81 full of wafers.

[0040] See also Fig. 9 and Fig.10 After the punch rod frame 103 is lifted to the upper position, the drive head 32 is not within the range of motion of the clutch drive block 15, so the punch needle does not move and remains in the uppermost position, and does not perform punching and embroidery. At this time, the color can be changed. The punch die 41 is about 28 mm away from the ultrasonic transducer 905, which greatly facilitates the cloth pulling and cloth changing operation.

[0041] See also Fig.11 and Fig.12 After the punch rod frame 103 descends to the lower position, the drive head 32 is within the movement range of the clutch drive block 15. When the jumping motor 17 is not working, it can perform punching embroidery, and when the jumping motor 17 is working, it can perform skipping embroidery.

[0042] See also Fig.13 and Fig.14 The fixing plate 909, the outer sleeve 910 and the heat dissipation aluminum sleeve 911 are provided with threads, and are installed to the frame through the fixing plate 909 after being tightened. The top cover 901, the outer sleeve 910 and the heat dissipation aluminum sleeve 911 together form an outer surrounding structure. The rubber bowl 906 is placed below the upper protrusion of the ultrasonic transducer 905, and an O-ring is placed above the upper protrusion of the ultrasonic transducer 905. The ultrasonic transducer 905 is clamped by the inner sleeve 907 and the inner sleeve cover 903. The inner sleeve and the outer surrounding structure are padded with O-rings. The outer diameter of the inner sleeve is smaller than the inner diameter of the outer sleeve 910. The bottom of the inner sleeve is pressed against the inner sleeve 910 through the buffer spring 908. When the punching needle 42 impacts the wafer to the cloth surface, it will impact the top surface of the ultrasonic transducer 905. At this time, it is protected by the buffer spring 908 to play a buffering role, so that the embroidery cloth will not be damaged, and the punching mechanism is also protected. Below the outer surrounding structure is an aluminum heat dissipation sleeve 911, which is provided with heat dissipation holes to prevent overheating due to long-term operation of the ultrasonic transducer 905. The ultrasonic transducer 905 is also equipped with an ultrasonic generator, which is not shown in the figure.
