As also shown in fig. 2 and 6, the heating wire cutting mechanism 60 may include a third jaw cylinder 61, a heating wire scissor 62, and a fourth driving cylinder 63. The third gripper cylinder 61 faces the cotton thread 1 with its gripper portion; the heating wire scissors 62 are provided on the claw portions of the third claw cylinder 61, and open and close with the claw portions, so that the heating wire 2 on the cotton thread 1 can be cut off, and the spiral heating wire formed on the cotton thread 1 and the heating wire 2 on the heating wire feeding mechanism 50 can be separated.

The fourth driving cylinder 63 is connected to and drives the third gripper cylinder 61 to move back and forth in the direction approaching and moving away from the cotton thread 1. When the heating wire 2 needs to be cut off, the fourth driving cylinder 63 acts to drive the third paw cylinder 61 to move to approach the cotton thread 1 until the heating wire scissors 62 are aligned to approach the heating wire 2 on the cotton thread 1; after the heating wire 2 is sheared, the fourth driving cylinder 63 acts to drive the third paw cylinder 61 to move away from the cotton thread 1.

In the present embodiment, the fourth driving cylinder 63 is mounted on the second bracket 42 through the support base 64, so that the heating wire cutting mechanism 60 and the rotating mechanism 40 form an integral module. Of course, in other embodiments, the fourth driving cylinder 63 may be mounted on the base 10 through the support base 64, so that the heater cutting mechanism 60 is independent of the rotating mechanism 40.

As shown in fig. 1 and 12, the take-off mechanism 70 may include a third bracket 71 mounted on the frame 10, a rotary cylinder 72 mounted on the third bracket 71, a fifth drive cylinder 73 disposed on the rotary cylinder 72, and a fourth gripper cylinder 74 disposed on the fifth drive cylinder 73.

The third bracket 71 may be positioned in parallel on one side of the first bracket 31, and the revolving cylinder 72 is disposed on the side of the third bracket 71 facing the rotating mechanism 40. The fifth driving cylinder 73 is fixed to the rotation shaft of the rotation cylinder 72 and rotates with the rotation of the rotation shaft. The fourth gripper cylinder 74 is connected to the telescopic rod of the fifth driving cylinder 73, and is driven to move back and forth in a direction approaching and separating from the cotton thread 1 with respect to the third bracket 71 by telescopic driving.

The fourth gripper cylinder 74 has a blade 75 provided on the gripper portion thereof in the direction of the cotton thread 1. The blade 75 opens and closes with the hand claw portion, and is used for cutting the cotton thread 1. The claw portion of the fourth claw cylinder 74 is further provided with a clamping piece 76, and the clamping piece 76 is located on one side of the blade 75 and is used for clamping the heating component. Between the cotton thread rotating mechanism 30 and the continuous rotation mechanism 40, the blade 75 is located at a side of the fourth gripper cylinder 74 where the gripper portion faces the cotton thread rotating mechanism 30, and the clip 76 is located at a side of the fourth gripper cylinder 74 where the gripper portion faces the continuous rotation mechanism 40.

When the material taking mechanism 70 works, the rotary cylinder 72 acts to drive the fifth driving cylinder 73 to rotate, and the fourth paw cylinder 74 is driven to rotate between the first rotating plate 32 and the second rotating plate 42. The fifth driving cylinder 73 is operated to drive the fourth gripper cylinder 74 to move close to the cotton thread 1, so that the gripper portion of the fourth gripper cylinder 74 is aligned between the cotton thread 1 and the heat generating component formed by winding, the gripper portion is operated to drive the clamping piece 76 to clamp the heat generating component, and meanwhile the blade 75 is used for cutting the cotton thread 1, so that the heat generating component is separated from the cotton thread 1. The fifth driving cylinder 73 is operated again to drive the fourth paw cylinder 74 to move away from the cotton thread 1, and the rotary cylinder 72 is operated again to drive the fifth driving cylinder 73 to rotate to drive the fourth paw cylinder 74 to rotate to the outer sides of the cotton thread rotating mechanism 30 and the continuous rotating mechanism 40.

When the cotton thread rotating device is used for preparing a heating component, cotton thread 1 is discharged from the cotton thread feeding mechanism 20 and passes through the cotton thread rotating mechanism 30 to the continuous rotating mechanism 40, and the free end of the cotton thread 1 is clamped by the second cotton thread clamping component 43 of the continuous rotating mechanism 40. The thread feeding mechanism 20 operates to screw the thread 1, and the thread pulling mechanism 80 operates to clamp the thread 1 after the screw is screwed, and then straightens the thread 1 between the rotating mechanism 40 and the thread pulling mechanism 80.

After the cotton thread 1 is straightened, the first cotton thread clamping assembly 33 of the cotton thread rotating mechanism 30 acts to clamp the cotton thread 1, the heating wire feeding mechanism 40 sends the heating wire 2 to the cotton thread 1 between the first cotton thread clamping assembly 33 and the second cotton thread clamping assembly 43, and the heating wire clamping assembly 34 of the cotton thread rotating mechanism 30 acts to clamp one end of the heating wire 2, so that the sent heating wire 2 is tangent to the cotton thread 1.

The cotton thread rotating mechanism 30 and the continuous rotating mechanism 40 are simultaneously operated so that the first rotating plate 32 and the second rotating plate 42 are rotated in synchronization. The heating wire clamping assembly 34 rotates along with the rotation to enable the heating wire 2 to be wound on the cotton thread 1, meanwhile, the heating wire feeding mechanism 40 sends out the heating wire 2 and drives the heating wire 2 to axially move relative to the cotton thread 1 through the swinging action of the swinging unit 57 of the heating wire feeding mechanism, and then the heating wire 2 wound on the cotton thread 1 generates a screw pitch to form a spiral heating wire with a certain number of turns, and the heating wire feeding mechanism and the cotton thread 1 form a heating assembly.

After winding of one heating component is completed, the heating wire cutting mechanism 60 acts to cut off the heating wire 2, so that the spiral heating wire is disconnected from the heating wire 2 on the heating wire feeding mechanism 40. The wire pulling assembly 46 of the rotating mechanism 40 acts to clamp the cotton thread 1 of the heating wire assembly through the second cotton thread clamp 463, after the first cotton thread clamping assembly 33 and the second cotton thread clamping assembly 43 loosen the cotton thread 1, the pulling assembly 46 acts to drive the first paw air cylinder 462 to move in a direction away from the cotton thread rotating mechanism 30, the second cotton thread clamp 463 is driven to move in the same direction, and meanwhile the clamped heating wire assembly also moves between the second cotton thread clamp 463 and the first cotton thread clamping assembly 33. The first yarn gripping assembly 33 operates to grip both ends of the heating wire assembly together with the second yarn gripping assembly 463.

The material taking mechanism 70 is used for clamping the heating wire component and cutting the heating wire component from the cotton thread 1, clamping the heating wire component, discharging, and fully mechanically and automatically completing winding of the heating wire on the cotton thread to manufacture the heating component.
