[0038] Embodiment:

[0039] As Figures 1-5As shown, the ultrasonic sewing machine material piece feeding mechanism of the application comprises a material disc 100, a guide roller 200 and a guide block 300 matched with the material disc 100. The material disc 100 is installed on a material disc mounting frame, the material piece mounting frame is fixed on the side wall of the head of the ultrasonic sewing machine away from the staff, the guide roller 200 is installed on the lower part of the side wall of the mechanism close to the staff, and the guide block 300 is installed on the transmission mechanism. The guide block 300 has a sliding guide surface 301, which is arc-shaped. The material piece wound on the material disc 100 enters the work station in turn after passing through the sliding guide surface 301 of the guide block 300 and the guide roller 200. Through the above structural design, the material piece gradually enters the work station under the rolling friction of the transmission mechanism. The transmission mechanism drives the cloth and the material piece in the work station to move forward. The cloth and the material piece are welded under the action of the ultrasonic generator, and the wireless sewing is completed. Since the material piece feeding mode of the embodiment is adopted, the placement position of the material can be ensured to be completely consistent every time, the sewing position is accurate, the quality and consistency of the finished product are guaranteed, and the cloth material port will not wrinkle, avoiding material waste. At the same time, the feeding speed is relatively large, which matches the maximum production capacity of the machine, and significantly increases the production efficiency. In addition, since the feeding does not need manual operation, even if the same action is repeated, it will not cause fatigue, reducing the possibility of errors. The fingers and other body parts of the staff are not close to the work area, reducing the risk of injury.

[0040] Specifically, one edge of the sliding guide surface 301 is provided with a fixed protrusion 302, and the other edge of the sliding guide surface is provided with a limiting piece 303. The limiting piece 303 is provided with a first waist-shaped hole 3031 and a second waist-shaped hole 3032. Two bolts are respectively connected with two bolt holes 304 on the sliding guide surface 301 through the first waist-shaped hole 3031 and the second waist-shaped hole 3032, so as to fix the limiting piece 303 on the sliding guide surface 301. Through the above structural design, the positions of the two bolts in the first waist-shaped hole 3031 and the second waist-shaped hole 3032 can be adjusted by loosening the two bolts, so as to adjust the distance between the limiting piece 303 and the fixed protrusion 302, thereby meeting the limiting requirements of material pieces of different widths.

[0041] Specifically, two limiting rings 201 are arranged side by side on the guide roller 200, and a limiting groove is formed between the two limiting rings for limiting the material piece.

[0042] Specifically, it also includes a guide device 400, which is also installed on the machine head and located on the feeding path of the material sheet. The guide device 400 includes two guide units 401. Each guide unit 401 includes a U-shaped bracket 4011 and two limiting posts 4012 slidably sleeved between the U-shaped brackets. The top of each limiting post 4012 is provided with a screw hole, in which an adjusting bolt 4013 is installed. The adjusting bolt 4013 can abut against the U-shaped bracket 4011. Similarly, by tightening or loosening the two adjusting bolts 4013, the position of the two limiting posts 4012 or the distance between them can be adjusted, thereby meeting the limiting requirements for feeding materials of different widths.

[0043] Specifically, to ensure that the sheet has appropriate tension during processing, remains flat and stable, reduces wrinkles, stretching or other deformations, and guarantees the quality of the final product, this embodiment also includes a sheet tension adjustment mechanism 500 located on the sheet feeding path. The sheet tension adjustment mechanism 500 is installed in the middle of the side wall of the machine head near the operator. The sheet tension adjustment mechanism 500 includes an adjustment motor 501 mounted on an adjustment motor mounting bracket 505 and an adjustment roller 502 connected to the output shaft of the adjustment motor 501. When the sheet passes through the adjustment roller 502, the tension of the sheet is affected by changing the rotation speed of the adjustment motor 501. Increasing the speed of the adjustment motor 501 reduces the tension, and vice versa.

[0044] As a preferred embodiment, in order to accurately adjust the tension of the material sheet, a tension sensor 503 is provided on the side of the adjusting roller 502, and a material sheet gap 504 is provided between the adjusting roller 502 and the tension sensor 503. By setting the tension sensor 503, the tension of the material belt can be monitored in real time, and the data can be fed back to the control system, so as to adjust the speed or torque of the tension motor 501 according to actual needs to maintain the ideal tension level.

[0045] As a preferred mode of the embodiment, in order to improve the stability and smoothness of the material sheet during the transmission process, the material sheet tension adjusting mechanism 500 further comprises a first auxiliary guide roller 506 and a second auxiliary guide roller 507, two first auxiliary guide roller limiting rings 5061 are arranged side by side on the first auxiliary guide roller 506, the two first auxiliary guide roller limiting rings 5061 form a limiting groove for limiting the material sheet, two second auxiliary guide roller limiting rings 5071 form a limiting groove for limiting the material sheet; two second auxiliary guide roller limiting rings 5071 are arranged side by side on the second auxiliary guide roller 507, the two second auxiliary guide roller limiting rings 5071 form a limiting groove for limiting the material sheet; the first auxiliary guide roller 506 and the second auxiliary guide roller 507 are both mounted on the adjusting motor mounting frame; the material sheet passing through the adjusting roller 502 passes through the first auxiliary guide roller 506 and the second auxiliary guide roller 507 in turn and then winds around the guide roller 200.

[0046] In summary, the above structure design solves the deficiencies in the prior art, and has the characteristics of reasonable structure, high efficiency, high safety, etc.

[0047] The above is a further detailed description of the utility model in combination with specific preferred embodiments, and cannot be considered as limiting the specific implementation of the utility model to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, and all of them should be considered as the protection scope of the utility model.
