A swing arm cylinder 3 is also fixed on the main support of the equipment, and the air circuit of the swing arm cylinder 3 adopts cylinder pressure-maintaining positioning, and the winding turret 4 is located on one side of the swing arm cylinder 3. The working end of the swing arm cylinder 3 is connected with a splicing and cutting component 1, and the splicing and cutting component 1 is also rotatably arranged on the main support of the equipment through a rotating shaft. An encoder 2 is connected to one side of the splicing and cutting component 1. The encoder 2 is connected to an industrial control PLC in a wired manner, and the industrial control PLC controls the cylinder. Specifically, the industrial control PLC controls the cylinder rod of the swing arm cylinder 3 to extend, retract or stop at any position according to the position signal feedback read by the encoder 2, and then the cylinder body maintains pressure, that is, the splicing and cutting component 1 rises, falls or stops at any position.

8. The automatic reeling and splicing method according to claim 6, characterized in that: The specific operation method of S1 is as follows: The encoder (2) reads the specific position and rotation direction signal of the splicing and cutting component (1) and transmits it to the industrial control PLC. The industrial control PLC controls the swing arm cylinder (3) to complete the corresponding upper cutting mode / lower cutting mode switching of the splicing and cutting component (1) according to the position signal feedback. When the cylinder rod of the swing arm cylinder (3) is fully retracted, it is the initial position of the upper cutting mode, and when the cylinder rod of the swing arm cylinder (3) is fully extended, it is the initial position of the lower cutting mode. The industrial control PLC confirms the working mode of the splicing and cutting component (1) according to the position signal feedback of the encoder (2), and then controls the cutting cylinder (1-8) to switch the cutting blade position. When the cylinder rod is extended, it is the upper cutting mode, at which time the lower cutting blade (1-6) is extended. When the cylinder rod is retracted, it is the lower cutting mode, at which time the upper cutting blade (1-7) is extended. The installation position of the guide roller device (1-3) is manually changed to switch the material feeding route. The upper feeding mode is the upper cutting mode, and the lower feeding mode is the lower cutting mode.
