Please refer to fig. 1 to 5. Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples.
It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the invention to the extent that it can be practiced, since modifications, changes in the proportions, or adjustments of the sizes, which are otherwise, used in the practice of the invention, are included in the spirit and scope of the invention which is otherwise, without departing from the spirit or scope thereof. Also, the terms "left", "right", "upper", "lower" and "a" are used herein for descriptive purposes only and are not intended to limit the scope of the invention as embodied or construed in any manner without substantially altering the technical context.
Referring to fig. 1 and 2, the pirn paying-off constant tension device comprises a bracket 1, a bobbin 2, a moment control part 3, a chuck 4, a gas cap 5, a mounting piece 6, a cylinder 7, a carrier roller 8 and a sensor 9. The bracket 1 comprises a first mounting plate 11, a second mounting plate 12, a third mounting plate 13, a base 14 and a groove 15, wherein the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 are vertically welded on the base 14, and the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 are mutually parallel. The torque control part 3 and the bobbin 2 are respectively arranged on two sides of the first mounting plate 11, and the torque control part 3 is connected with the bobbin 2. The chuck 4 is arranged between the bobbin 2 and the first mounting plate 11, and the bobbin 2 is fixed by the chuck 4. The air cap 5 is mounted on the second mounting plate 12 through the mounting piece 6, and the thimble 51 of the air cap 5 is sleeved with the chuck 4. The air cylinder 7 is fixedly arranged on the third mounting plate 13, the telescopic rod 71 of the air cylinder 7 is connected with the air cap 5, and the second mounting plate 12 is connected with the third mounting plate 13. The carrier roller 8 is arranged below the air cap 5 and the bobbin 2 and is close to the base 14, the carrier roller 8 is in a rolling pin shape, and two ends of the carrier roller 8 are respectively arranged on the first mounting plate 11 and the second mounting plate 12. The sensor 9 is installed on the outer side of the carrier roller 8, and the sensor 9 is installed on the base 14.
In particular, the torque control means 3 is a magnetic powder brake, but may also be other torque control means, such as a servo motor.
Further, as the coil wound on the bobbin 2 becomes smaller and the rotation speed becomes faster, the torque control part 3 provides a reverse torque control rotation speed, so that the bobbin 2 is stably rotated.
Specifically, the sensor 9 outputs an analog signal that continuously changes according to the outer diameter of the coil on the bobbin 2, which is equivalent to a regulator controlling the exciting current of the torque control part 3, and generates a certain torque through the exciting current, and generates reverse torque to the bobbin 2 to control the rotation speed.

In particular, the reciprocating movement of the air cap 5 and the air cylinder 7 facilitates the replacement of the bobbin 2. When the bobbin 2 needs to be replaced, the telescopic rod 71 of the air cylinder 7 drives the air cap 5 to shrink, so that the bobbin 2 is conveniently taken out; after the replacement is completed, the telescopic rod 71 of the air cylinder 7 pushes the air cap 5 to push the bobbin 2 to the first mounting plate 11, the thimble 51 and the chuck 4 on the rotating shaft 31 are tightly attached to the bobbin 2, the chuck 4 enables the two ends of the bobbin 2 to be uniformly stressed and fixed, and the air cap 5 locks the bobbin 2 through the air cylinder 7.
As shown in fig. 4 and 5, the first mounting plate 11 and the second mounting plate 12 are respectively provided with two symmetrical grooves 15, two ends of the carrier roller 8 are embedded into the grooves 15 and fixedly mounted through bolts, two sides of the bobbin 2 are respectively provided with one carrier roller 8, and the carrier rollers 8 are attached to two ends of the bobbin 2. The sensor 9 is arranged on the base 14.
Specifically, the carrier roller 8 is rotatable, and is attached to two ends of the bobbin 2 to assist the bobbin 2 to rotate.
In particular, the sensor 9 is used to measure the outer diameter of the coil wound on the bobbin 2.
Further, the sensor 9 is an ultrasonic sensor, detects the outer diameter of the wound coil on the bobbin 2 in real time, and outputs a signal to the torque control part 3, and the torque control part 3 provides reverse torque force to the bobbin 2 to control the rotation speed, so that the bobbin stably rotates.
Further, the mounting position of the sensor 9 is not fixed, and may be mounted at any position where the outer diameter of the coil can be detected according to the actual situation.
In summary, the torque control part is used for controlling the rotating speed by the reverse torque, so that the wire harness on the bobbin always keeps tension, the wire harness is prevented from being disordered or even knotted, the reverse torque is detected and regulated in real time through the sensor, and the tension is regulated in real time.
