[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figure 1-5 An ultrasonic welding machine for toothbrush production is shown, including a base 1 and a turntable 10 mounted on the upper side of the base 1. Multiple limiting grooves 9 are provided inside the upper outer wall of the turntable 10 to limit the placement of the brush head and brush handle. The body 5 is located on the upper side of the turntable 10; An ultrasonic welding machine body 13 is installed on the lower outer wall of the machine body 5. A welding torch 12 is fixedly connected to the lower outer wall of the ultrasonic welding machine body 13. The operator places the brush head and brush handle into the limiting groove 9 of the turntable 10, ensuring that they fit tightly against the inner wall of the limiting groove 9 to achieve precise positioning. The operator starts the drive device of the turntable 10, causing the turntable 10 to rotate slowly, rotating the limiting groove 9 with the brush head and brush handle placed therein to the welding position below the welding torch 12. When the limiting groove 9 reaches the welding position, the ultrasonic welding machine body 13 starts, and the welding torch 12 descends and... When the brush head and handle are in contact with the parts to be welded, the welding torch 12 applies a certain pressure and transmits ultrasonic vibration energy to the welding parts, causing the material to heat up, soften and fuse. The welding process is carried out according to the preset welding time and power. After the welding time is over, the welding torch 12 stops vibrating and rises, completing the welding of a set of brush heads and handles. The turntable 10 continues to rotate, sending the next set of placed brush heads and handles to the welding position. The above welding operation is repeated. When the toothbrush semi-finished product reaches the unloading position, the operator takes it out from the limiting groove 9, completing the entire welding and protection process. Each of the multiple limiting grooves 9 has a cover 18 on its upper side. After each set of brush heads and brush handles is welded, as the turntable 10 rotates, the cover 18 flips down to accurately cover the welding position and prevent dust and impurities from falling in. When the operator takes out the welded toothbrush, the cover 18 flips up again to wait for the next flip.
[0022] like Figure 4 As shown, a fixing strip 16 is provided on the lower side of each of the multiple covers 18, and a fixing shaft 17 is provided between each of the multiple covers 18 and the fixing strip 16 to limit the position of the center of the cover 18 when it flips. A soft pad 19 is fixedly connected to the lower outer wall of each of the multiple covers 18 to reduce the impact force when the cover 18 flips down.
[0023] The fixed shaft 17 restricts the position of the center of rotation of the cover 18, so that the cover 18 can only rotate around the fixed shaft 17, ensuring the stability and accuracy of the rotation action of the cover 18.
[0024] like Figure 5 As shown, a lever 21 is provided on the upper side of the turntable 10 to guide the cover 18 in the open state to flip downward. A fixing block 20 is fixedly connected to the outer wall of the rear end of the lever 21 to limit the position of the lever 21.
[0025] When the turntable 10 rotates, the cover 18 in the open state will contact the lever 21. As the turntable 10 continues to rotate, the lever 21 pushes the cover 18, causing it to flip downward around the fixed axis 17.
[0026] like Figure 1 and Figure 3 As shown, a fixed seat 2 is fixedly connected to the upper outer wall of the base 1, a fixed frame 3 is fixedly connected to the upper outer wall of the fixed seat 2, a first drive motor 6 is fixedly connected to the upper outer wall of the fixed frame 3, a threaded rod 14 is provided on the lower side of the first drive motor 6, and a limit block 15 is screwed onto the circular outer wall of the threaded rod 14 so that when the threaded rod 14 rotates, it drives the machine body 5 to move up and down.
[0027] The base 1 has a fixed seat 2 that supports and fixes the fixed frame 3. The first drive motor 6 connected to the upper outer wall of the fixed frame 3 is the power source for the lifting of the body 5. The rotational motion of the first drive motor 6 is transmitted to the threaded rod 14 connected to it, causing the threaded rod 14 to rotate around its own axis. Since the circular outer wall of the threaded rod 14 is screwed into the limiting block 15, according to the principle of thread transmission, when the threaded rod 14 rotates, the limiting block 15 will move along the axial direction of the threaded rod 14.
[0028] like Figure 3 As shown, a second drive motor 11 is fixedly connected to the lower outer wall of the base 1 to drive the turntable 10 to rotate. Both the first drive motor 6 and the second drive motor 11 are electrically connected to an external power source.
[0029] The second drive motor 11, which is fixedly connected to the lower outer wall of the base 1, provides power for the rotation of the turntable 10. After the second drive motor 11 is connected to the external power supply, the electromagnetic induction inside the motor causes the rotor to generate a rotational torque. The output shaft of the second drive motor 11 is directly or through a transmission mechanism connected to the turntable 10, transmitting the rotational motion of the motor to the turntable 10, and driving the turntable 10 to rotate around its central axis.
[0030] like Figure 1 As shown, a display screen 8 is provided on the front outer wall of the body 5, and multiple operation buttons 7 are provided on the right side of the display screen 8. An emergency stop button 4 is provided on the front outer wall of the body 5 near the right side.
[0031] The display screen 8, located on the outer wall of the front of the machine body 5, serves as a crucial window for information exchange between the equipment and the operator. Through LCD technology, it intuitively displays various operating parameters, status information, and operational prompts. When an operator presses an operation button 7, the internal circuit contacts close, generating an electrical signal. This signal is transmitted to the control motherboard via the internal circuitry. Upon receiving the signal, the control motherboard controls the corresponding functions of the equipment according to preset programs and logic. In case of emergencies, such as abnormal noises or smoke from the equipment, or if the operator discovers a situation that may endanger their safety, pressing the emergency stop button 4 immediately opens the normally closed contacts inside the button. This action cuts off the main control or power circuit of the equipment, causing critical components such as the first drive motor 6, the second drive motor 11, and the ultrasonic welding machine body 13 to immediately stop working, thus quickly halting the equipment's operation, preventing further escalation of the accident, and ensuring the safety of personnel and equipment.
[0032] The implementation principle of this embodiment is as follows: The operator places the brush head and brush handle into the limiting groove 9 of the turntable 10, ensuring that they fit tightly against the inner wall of the limiting groove 9 to achieve precise positioning. The drive device of the turntable 10 is activated, causing the turntable 10 to rotate slowly, rotating the limiting groove 9 with the brush head and brush handle in place to the welding position below the welding torch 12. When the limiting groove 9 reaches the welding position, the main body 13 of the ultrasonic welding machine is activated, the welding torch 12 descends and contacts the parts of the brush head and brush handle to be welded, the welding torch 12 applies a certain pressure, and transmits ultrasonic vibration energy to the welding part, causing the material to heat up, soften, and fuse. The welding process proceeds according to... The welding process proceeds according to the preset welding time and power. After the welding time is completed, the welding torch 12 stops vibrating and rises, completing the welding of a set of brush heads and handles. The turntable 10 continues to rotate, sending the next set of placed brush heads and handles to the welding position. The above welding operation is repeated. When the toothbrush semi-finished product reaches the unloading position, the operator takes it out from the limiting groove 9, completing the entire welding and protection process. After each set of brush heads and handles is welded, as the turntable 10 rotates, the cover 18 flips down, accurately blocking the welding position to prevent dust and impurities from falling in. When the operator takes out the welded toothbrush, the cover 18 flips up again, waiting for the next flip.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
