[0021] The following is combined with Figure 1 and Figure 2 The present invention will be further described below:

[0022] ①The automatic bubble twisting machine of this utility model consists of a power connection cable 1, a drive device 3, a control panel 204 and a housing 2.

[0023] ② The power connection cable 1 includes a wire 102. One end of the wire 102 is connected to the power source by a plug 101, and the other end is introduced into the housing 2 to supply power to the internal components of the automatic bubble twisting machine.

[0024] ③The housing 2 consists of multiple outer shells 201 and bolts 202 for fixing the outer shells. A support base 203 is provided at the bottom of the outer shell 201. The support base 203 is made of rubber and is used to support the entire outer shell 201, while also having an anti-slip function.

[0025] ④ A control panel 204 is installed on the housing 2. The control panel is equipped with a speed adjustment knob 2041, a power switch 2042 and a reversing lever 2043.

[0026] ⑤ The interior of the housing 2 is the drive device 3, which includes a speed-regulating motor 301, a drive shaft 302, a turntable 303, and a drive circuit board 304. The speed-regulating motor 301 and the control panel 204 together form a control unit through the drive circuit board 304. The rotation speed and torque output value of the speed-regulating motor 301 can be set by the speed-regulating knob 2041. The forward and reverse rotation of the speed-regulating motor 301 can be adjusted by the reversing lever 2043, which can tighten and loosen the bulb. The power switch 2042 controls the power supply of the entire drive device 3.

[0027] ⑥ The drive circuit board 304 is used to perform feedback adjustment based on the torque, speed, and other parameter values ​​input from the control panel 204, and output corresponding adjustment signals to the speed-regulating motor 301; at the same time, it collects the current motor torque output value in real time from the torque sensor 3041 set on the drive shaft, performs comparative analysis, and then controls the start and stop of the speed-regulating motor 301 to prevent excessive torque output from damaging the product. The drive shaft 302 drives the turntable 303 to rotate, and compares the torque set value with the feedback data from the real-time torque sensor 3041 to control the output of the speed-regulating motor 301.

[0028] ⑦ The turntable 303 consists of a large turntable 3031 connected to the drive shaft, a concave small turntable 3032, and a silicone pad 3033; the concave small turntable 3032 is a detachable part, and the large turntable 3031 and the concave small turntable 3032 are embedded together. According to the size of different bulbs, the corresponding concave small turntable 3032 can be replaced to match different bulbs.

[0029] ⑧ The silicone pads 3033 are evenly distributed on the concave surface of the small turntable 3032, which can increase the friction between the turntable and the bulb shell and play a role in preventing slipping; at the same time, since silicone is a soft material, it can reduce the scratches on the bulb by the turntable during the rotation process.
