The rotating shaft 110 of the rotary driving element 100 is fixedly connected with the tape feeding element 300, and the rotating shaft 110 of the rotary driving element 100 and the conveying surface 310 of the tape feeding element 300 are arranged at an included angle, so that the rotary driving element 100 operates to drive the tape feeding element 300 to rotate around the rotating shaft 110 of the rotary driving element 100, and further, the angle of the conveying surface 310 of the tape feeding element 300 can be adjusted, so that the soft shielding layer tape can be conveyed to a winding position at different conveying angles to adapt to sleeves of different specifications. The slider 400 is fixed to the tape feeder 300 so that the slider 400 can move in synchronization with the tape feeder 300, the telescopic shaft 210 of the telescopic driver 200 abuts against the guide surface of the slider 400, and the telescopic shaft 210 of the telescopic driver 200 can move along the guide surface with respect to the slider 400 when it is telescopic.

Referring to fig. 1 and 2, when the rotation of the rotary driving member 100 is not started, the tape feeding member 300 is at the initial position, and the telescopic shaft 210 of the telescopic driving member 200 is freely extended and pressed against the guide surface of the slider 400 with a small pressing force. Referring to fig. 3 to 5, when the conveying angle of the tape feeder 300 needs to be adjusted, the rotary driving unit 100 is started to rotate by a predetermined angle, the tape feeder 300 and the slider 400 are driven by the rotary driving unit 100 to rotate synchronously with the tape feeder 300 and the slider 400, in the process, the telescopic shaft 210 is contracted under the guidance of the guide surface of the slider 400 and keeps abutting against the guide surface, and the tape feeder 300 can be accurately stopped at the predetermined angle under the influence of the pressing force of the telescopic shaft 210 on the first guide part 410, so that the tape feeder 300 can accurately convey the soft shielding layer tape to the winding position at the predetermined angle; when the tape feeding unit 300 needs to be reset, the telescopic driving unit 200 is started to extend, in the process, the telescopic shaft 210 extends, and the slider 400 is pushed by the telescopic shaft 210 to rotate around the rotating shaft 110 in the opposite direction until the tape feeding unit 300 is reset under the guiding action of the first guiding portion 410 on the telescopic shaft 210.

For convenience of description, the guide surfaces located at both sides of the telescopic shaft 210 when the tape dispenser is at the initial position are respectively defined as a first guide portion 410 and a second guide portion 420.

It should be noted that, when the telescopic shaft 210 extends to the maximum, the tape feeder 300 is just at the initial position, and under the restriction of the first guide part 410 and the second guide part 420, there is no need to worry about the tape feeder 300 passing through the initial position, and the resetting accuracy is high; in addition, when no external force is applied, the first guide portion 410 and the second guide portion 420 can clamp the telescopic shaft 210 at the position, so that the telescopic shaft 210 at the initial position is not easily deviated, and stability is good.

Specifically, the first guide portion 410 is inclined toward the retracting direction of the telescopic shaft 210 along the forward rotation direction of the rotating shaft 110 (wherein, the forward rotation direction of the rotating shaft 110 is not the absolute forward rotation direction, but for convenience of description, one rotation direction of the rotating shaft 110 is defined as the forward rotation direction so as to be distinguished from the other rotation direction of the rotating shaft 110), so that the telescopic shaft 210 abutting against the first guide portion 410 is adapted to retract while the rotating shaft 110 drives the belt feeding member 300 to rotate forward; accordingly, the slider 400 can drive the tape feeding member 300 to rotate reversely and reset while the telescopic shaft 210 is extended. The second guide portion 420 is inclined toward the contraction direction of the telescopic shaft 210 in the reverse rotation direction of the rotation shaft 110, that is, the second guide portion 420 is inclined in the opposite direction to the first guide portion 410, so that the end of the second guide portion 420 is abutted to the end of the first guide portion 410 to form a concave structure.

Specifically, a first mounting hole may be formed in the fixing member 214, and the telescopic shaft body 211 and the first mounting hole are in interference fit, so that the fixing member 214 and the telescopic shaft body 211 can be fixed.

A first threaded connector can be connected between the bearing seat 213 and the fixing member 214, and the bearing seat 213 and the fixing member 214 are fastened together by the first threaded connector, so that the bearing seat 213 and the fixing member 214 can be fixedly connected. Wherein, a bolt can be used as the first threaded connector.

The second mounting holes may be formed at both ends of the bearing housing 213, and both ends of the fixing shaft are respectively interference-fitted with the second mounting holes, so that the fixing of the fixing shaft and the bearing housing 213 may be achieved.

The stationary shaft may be in interference fit with the central bore of the bearing 212 to secure the stationary shaft to the bearing 212.

In addition, a controller can be additionally arranged in the specific structure of the belt angle adjusting device provided by the embodiment, the rotary driving piece 100 can be electrically connected with the controller, so that the controller is used for controlling the rotating direction and the rotating speed of the rotary driving piece 100, and the control is not needed, so that the belt angle adjusting device is higher in accuracy and more convenient; correspondingly, the telescopic driving member 200 can be electrically connected with the controller, so that the controller can be used for controlling the telescopic driving member 200 to stretch, and the use is more convenient.

In particular, a rotary electric machine may be used as the rotary actuator 100, and a telescopic cylinder may be used as the telescopic actuator 200.

In addition to using a rotary motor as the rotary driving member 100, the rotary shaft 110 and the tape feeding member 300 may be fixedly coupled to each other by a motor bushing.

Specifically, the belt feeding plate can be used as the belt feeding member 300 to feed the soft shielding layer belt material, so that the structure is simple, the material consumption is less, and the cost can be saved.

When the rotation axis 110 is perpendicular to the conveying surface 310 of the tape feeder 300, the soft shield layer tape is conveyed by the tape feeding plate, so that the rotation stability of the tape feeder 300 can be improved.

Preferably, referring to fig. 2 and 5, a limiting member 500 may be disposed at both ends of the guide surface, so that the telescopic shaft 210 is limited in the region corresponding to the guide surface by the limiting member 500, the telescopic shaft 210 is prevented from sliding out from both ends of the guide surface, and the structural reliability is ensured.

The second screw connector can be used as the limiting member 500, and the second screw connector can be screwed to the corresponding position of the sliding block 400 during assembly, so that the assembly is very convenient and the assembly efficiency is high.
