[0002] A pattern sewing machine is an automated sewing device widely used in clothing, bags, and home furnishings to sew specific and complex patterns onto materials. With technological advancements, ultrasonic technology has been introduced into pattern sewing machines, utilizing high-frequency vibration energy to sew, cut, or emboss thermoplastic materials such as synthetic fibers. Its advantages include no need for needles and thread, smooth cuts without burrs, and high efficiency.

[0003] In existing ultrasonic template machines, the device that enables the ultrasonic roller to rotate and press down is a key component. Traditional downward rotation devices are usually quite complex in structure, with some devices using multiple independent transmission systems to control rotation and pressing separately. This not only occupies a lot of space but also has high manufacturing costs and is inconvenient for debugging and maintenance.

[0004] Furthermore, traditional ultrasonic transducers mostly emit waves axially, resulting in a relatively simple interaction mode with materials, which can lead to low efficiency in certain applications. Additionally, the winding of wiring in rotating components of the transmission system, especially those transmitting electrical signals, presents a design challenge; improper handling can affect the stability and lifespan of the equipment.

[0005] Therefore, there is an urgent need in this field for a template machine ultrasonic downward rotation device with a simpler structure, higher integration, stable operation, and convenient maintenance, in order to overcome the above-mentioned defects in the prior art. Utility Model Content

A first bearing seat is provided at the upper and lower ends of the gearbox, and the rotary shaft is supported on the gearbox through the two first bearing seats. An electric slip ring is fixed at the lower end of the rotary shaft.

[0008] As a further technical solution of this utility model, the bevel gear pair includes a first bevel gear arranged horizontally and a second bevel gear arranged vertically.

Detailed Implementation

[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0017] This embodiment provides an ultrasonic downward rotating device for a template machine, such as... Figure 1 As shown, the device includes a rotating ultrasonic component 1, a rotating transmission component 2, and a rotating shaft 3. The rotating ultrasonic component 1 and the rotating transmission component 2 are rotatably connected by the rotating shaft 3. The rotating shaft 3 is vertically fixed inside the rotating transmission component 2, and both ends of the rotating shaft 3 extend out of the rotating transmission component 2. During operation, the rotating ultrasonic component 1 can rotate horizontally under the drive of the rotating transmission component 2.

[0018] The rotary transmission assembly 2 includes a gearbox 21, a bevel gear pair 22, a first motor 23, and a rotating shaft 3. The bevel gear pair 22 is fixed inside the gearbox 21. The first motor 23 is fixedly connected to one side of the gearbox 21. The bevel gear pair 22 includes a horizontally arranged first bevel gear 221 and a vertically arranged second bevel gear 222. The first bevel gear 221 is fixed to the rotating shaft 3. The second bevel gear 222 is fixed to the output end of the first motor 23. With the above structure, the output torque of the first motor 23 changes the transmission direction through a pair of bevel gears, efficiently transmitting power to the vertical rotating shaft 3. The structure is compact and the transmission is smooth. A first bearing seat 24 is provided at each of the upper and lower ends of the gearbox 21. The rotating shaft 3 is fixed inside the gearbox 21 through the two first bearing seats 24, so that the rotary transmission assembly 2 supports the rotating shaft 3 without being affected by the rotating shaft 3, maintaining the stability of the device. An electric slip ring 25 is fixed at the lower end of the rotating shaft 3 for supplying power and transmitting signals to the rotating ultrasonic component 1.

[0019] The rotating ultrasonic component 1 includes an ultrasonic rotating base 11, a second motor 12, a driving wheel 13, a synchronous belt 14, a driven wheel 15, and a transducer 16. The ultrasonic rotating base 11 is fixed to the upper end of the rotating shaft 3 and rotates together with the rotating shaft 3. The second motor 12 is horizontally fixed inside the ultrasonic rotating base 11. The output end of the second motor 12 extends out of the ultrasonic rotating base 11 and is fixedly connected to the driving wheel 13. A second bearing seat 17 is installed on each of the left and right sides of the upper end of the ultrasonic rotating base 11. The transducer 16 is supported on the upper end of the ultrasonic rotating base 11 by the two second bearing seats 17. The driven wheel 15 is fixed in the middle of the transducer 16. The driving wheel 13 and the driven wheel 15 are connected by a synchronous belt 14. The synchronous belt structure not only allows the transducer 16 to be driven by the motor to rotate, but also has higher transmission efficiency and is easier to install than other types of transmission components. At the same time, due to the restraining effect of the synchronous belt 14, the overall structure of the device is more compact and stable.

[0020] During operation, the first motor 23 drives the rotating shaft 3 through the bevel gear pair 22, causing the entire rotating ultrasonic component 1 to rotate in the horizontal direction; at the same time, the second motor 12 drives the transducer 16 to rotate through the synchronous belt drive, realizing the composite motion of the transducer 16.

[0021] To detect the rotation angle of the rotating shaft in real time, a rotation sensing plate 26 is installed between the slip ring 25 and the gearbox 21. The rotation sensing plate 26 has an opening. A photoelectric switch 27, which cooperates with the rotation sensing plate 26, is installed below the gearbox 21. When the rotating shaft 3 drives the rotation sensing plate 26 to rotate, the photoelectric switch 27, by detecting the opening on the sensing plate, can accurately sense the specific position of the rotating shaft, realizing the positioning and control of the rotation angle, thus improving the automation level and processing accuracy of the device.

[0022] When the transducer 16 and the first motor 23 are operating, a large amount of heat is generated. Overheating of the device will lead to a decrease in the efficiency of the transducer 16, and high temperature will also degrade the performance of the first motor 23. To achieve rapid cooling of the transducer 16 during device operation, a fan 18 is fixed to one side of the rotating ultrasonic component 1. The fan 18 can effectively dissipate heat from the transducer 16 and surrounding components such as the second motor 12 during operation, keeping the device temperature within a safe range. This ensures that the device can operate stably for extended periods and extends its service life.

[0023] In this embodiment, the transducer 16 is a radial wave transducer. The transducer 16 includes at least one ultrasonic roller 19, which is fixed on the transducer 16 and located in the middle of the two second bearing seats 17. During operation, since the transducer 16 used in this embodiment is a radial wave transducer, the ultrasonic energy is radiated along the circumference of the roller 19, generating high-frequency vibration. The roller 19 can rotate with the transducer 16 in both its own rotation and horizontal rotation, enabling it to complete more complex and tight sewing, cutting, or embossing tasks. During operation, no matter how the horizontal rotation direction changes, the rotation of the roller 19 always allows it to contact the material in a rolling rather than sliding manner, greatly reducing friction and preventing the material from being stretched or damaged.

[0024] During normal processing, the first motor 23 starts, driving the second bevel gear 222 of the bevel gear pair 22, which in turn drives the first bevel gear 221 fixed on the rotating shaft 3, transmitting power to the rotating shaft 3, causing the rotating shaft 3 to drive the entire rotating ultrasonic assembly 1 to rotate around the vertical axis. Simultaneously, the second motor 12 starts, driving the transducer 16 to rotate via the driving wheel 13, synchronous belt 14, and driven wheel 15, thereby driving the ultrasonic roller 19 to rotate. When the transducer 16 is working, the ultrasonic roller 19 emits ultrasonic waves radially while rotating, cooperating with the upper roller of the template machine (not shown in the figure) to sew, cut, or emboss textiles or plastics. The rotation sensor 26 and photoelectric switch 27 work together to monitor the rotation angle of the rotating shaft 3 in real time, and the controller adjusts the speeds of the first motor 23 and the second motor 12 to ensure synchronization accuracy.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
