[0035] The unwind and rewind deviation rectifying device 100 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0036] Referring to Figure 1 and Figure 6 , the unwind and rewind deviation rectifying device 100 according to an embodiment of the present utility model includes a base 10, a support shaft 20, a deviation detection member 30, and a controller 40. The base 10 is used to provide support. The support shaft 20 is used to support the coil material. The support shaft 20 is rotatably connected to the base 10 and supported on the base 10. Along the axial direction of the support shaft 20, the support shaft 20 is movably connected to the base 10.

The controller 40 is electrically connected to the deviation detection member 30 and the support shaft 20 respectively to control the support shaft 20 according to the detection result of the deviation detection member 30. When the coil material is offset, the support shaft 20 is adjusted to move relative to the base 10 along its axial direction to correct the offset of the coil material.

[0037] Specifically, referring to Figure 1 , the unwind and rewind deviation rectifying device 100 in the embodiment of the present utility model includes a base 10, and the base 10 is used to provide support. The base 10 may be one or more than two. The structural shape of the base 10 is not limited and can be adjusted according to actual needs.

[0038] The rewinding and unwinding deviation rectifying device 100 further includes a support shaft 20. A coil material can be wound around the support shaft 20, or sleeved and fixed on the support shaft 20, etc. The support shaft 20 is rotatably connected to and supported by the base 10 so that the coil material supported on the support shaft 20 can be wound or unwound by rotation, and the base 10 plays a supporting role for the support shaft 20. Along the axial direction of the support shaft 20, the support shaft 20 is movably connected to the base 10, that is, the support shaft 20 can move relative to the base 10 along its axial direction. In this way, when the coil material deviates during the rewinding or unwinding process, the relative position between the support shaft 20 and the base 10 can be adjusted to correct the deviation to ensure that the edges of the material are aligned.

[0039] The rewinding and unwinding deviation rectifying device 100 further includes a deviation rectifying detection member 30. By the deviation rectifying detection member 30, it is detected whether the coil material wound or unwound by the support shaft 20 deviates, which is convenient for real-time detection of the position state of the coil material, does not require manual observation and detection, has a high detection accuracy, and reduces the labor cost.

Specifically, the controller 40 and the deviation rectifying detection member 30 can be electrically connected through a wire 90, or can be electrically connected through a wireless signal, etc. The controller 40 is electrically connected to the support shaft 20. According to the detection result obtained by the deviation rectifying detection member 30, when the coil material does not deviate, the controller 40 controls the support shaft 20 to remain stationary, and when the coil material deviates, the controller 40 controls the support shaft 20 to act, adjusts the support shaft 20 to move relative to the base 10 along its axial direction to correct the deviation of the coil material, and realizes automatic deviation rectification of the coil material.

[0041] Thus, referring to Figure 1 , according to the rewinding and unwinding deviation rectifying device 100 of the present utility model, the deviation rectifying detection member 30 is used to detect in real time whether the coil material deviates, and sends the detection result to the controller 40. The controller 40 controls the support shaft 20 to act according to the detection result, adjusts the relative position between the support shaft 20 and the base 10, so as to ensure that the edges of the coil material are aligned during the rewinding and unwinding process. The deviation rectifying effect is better, and manual detection and deviation rectification are not required, which improves the production efficiency and reduces the production cost.

[0042] In some embodiments, the deviation rectifying detection member 30 can be an infrared sensor, and its working principle is based on infrared sensing technology. By emitting and receiving infrared signals, it is judged whether the position of the coil material deviates. Or the deviation rectifying detection member 30 can also be an ultrasonic sensor. The ultrasonic sensor includes a transmitter and a receiver. The transmitter emits ultrasonic waves, and after the ultrasonic waves are reflected by the coil material, they are received by the receiver. The receiver converts the received ultrasonic wave signal into an electrical signal and transmits it to the controller 40 for processing.

By connecting the base body 50 and the support shaft 20 through the deviation rectifying assembly 60, the support shaft 20 can be moved to correct the deviation under the drive of the deviation rectifying assembly 60. By being electrically connected to the deviation rectifying assembly 60, the controller 40 can send a control signal to the deviation rectifying assembly 60, and the deviation rectifying assembly 60 acts to control the movement of the support shaft 20.

[0045] Specifically, referring to Figure 2 , the base body 50 and the base 10 can be connected through a rotating shaft, or can be connected through a bearing or the like.

[0046] In some embodiments, the base body 50 has an installation cavity, and the deviation rectifying assembly 60 is arranged in the installation cavity of the base body 50. The space utilization rate is improved, and the volume of the device is reduced.

One end of the deviation rectifying transmission member 62 is connected to the output shaft of the deviation rectifying driving member 61, and the other end is connected to the support shaft 20 to adjust the movement of the support shaft 20 relative to the base body 50 along its axial direction.

[0051] By providing the through-hole slip ring 51, the wire 90 is not easily wound, the service life of the wire 90 is extended, and the safe connection between the controller 40 and the deviation rectifying assembly 60 is ensured. The stator 511 is connected to the base 10 and is rotatably connected to the base body 50. In this way, the stator 511 is fixed and the wire 90 connected to the stator 511 will not rotate either. Therefore, it is not easily wound. The rotor 512 is electrically connected to the stator 511 and can transmit the electrical signal to the rotor 512 and then to the deviation rectifying assembly 60 to realize the electrical connection between the controller 40 and the deviation rectifying assembly 60.

[0053] Through the deviation rectifying driving member 61, deviation rectifying power can be provided for the deviation rectifying transmission member 62. The deviation rectifying transmission member 62 can transmit the power to the support shaft 20, causing the support shaft 20 to move axially for deviation rectification.

[0054] Specifically, the deviation rectifying driving member 61 is connected to the rotor 512 to receive the electrical signal received by the rotor 512 and start the driving action. The deviation rectifying driving member 61 is connected to the base body 50, and the base body 50 can provide support for the deviation rectifying driving member 61, the deviation rectifying transmission member 62, and the rotor 512. One end of the deviation rectifying transmission member 62 is connected to the output shaft of the deviation rectifying driving member 61, and the other end is connected to the support shaft 20 to transmit the output power of the deviation rectifying driving member 61 to the support shaft 20 and provide power for the movement of the support shaft 20 relative to the base body 50 along its axial direction.

[0056] In some embodiments, the deviation rectifying driving member 61 is connected by a plurality of driving fixing rods. Further, the plurality of driving fixing rods are uniformly distributed along the circumferential direction of the deviation rectifying driving member 61. The deviation rectifying driving member 61 can be a servo motor. The deviation rectifying driving member 61 and the deviation rectifying transmission member 62 can be directly connected or connected through a driving connecting member 64. For example, they can be connected through a coupling, etc.

[0057] In some embodiments of the present utility model, referring to Figure 2 , the deviation rectifying assembly 60 further includes a deviation rectifying connecting member 63. One end of the deviation rectifying connecting member 63 is threadedly connected to the deviation rectifying transmission member 62, and the other end is fixedly connected to the support shaft 20.

[0058] One end of the deviation rectifying connecting member 63 is threadedly connected to the deviation rectifying transmission member 62, that is, the deviation rectifying connecting member 63 is rotatably connected to the deviation rectifying transmission member 62, and the other end is fixedly connected to the support shaft 20. In this way, when the deviation rectifying transmission member 62 rotates, the deviation rectifying connecting member 63 can move relative to the deviation rectifying transmission member 62, so that the deviation rectifying connecting member 63 can drive the support shaft 20 to be movable relative to the base body 50 along its axial direction.

[0059] Specifically, the deviation rectifying connecting member 63 includes a sliding portion 631 and a connecting portion 632.

The deviation rectifying fixing seats 65 can be bearings, etc.

[0060] In some embodiments of the present utility model, referring to Figure 2 and Figure 4 , the winding and unwinding deviation rectifying device 100 further includes a support inner shaft 70. The support inner shaft 70 is fixedly connected to the base body 50. The support shaft 20 is sleeved outside the support inner shaft 70 and is coaxially arranged with the support inner shaft 70. The support shaft 20 is movably connected to the support inner shaft 70 along its axial direction.

[0061] By providing the support inner shaft 70 coaxial with the support shaft 20, support is provided for the support shaft 20, and the support shaft 20 can rotate and move stably.

The support shaft 20 is movably connected to the support inner shaft 70 along its axial direction to achieve movable connection with the base body 50.

[0063] In some embodiments of the present utility model, referring to Figure 2 and Figure 4, the deviation rectifying transmission member 62 is passed through the support inner shaft 70 and is rotatably connected to the support inner shaft 70; the support inner shaft 70 is provided with a through hole 71, the through hole 71 extends along the axial direction of the support inner shaft 70, the deviation rectifying connecting member 63 is passed through the through hole 71 and is connected to the support shaft 20.

[0064] The deviation rectifying transmission member 62 is connected to the support shaft 20 through the through hole 71 extending along the axial direction of the support inner shaft 70 to drive the support shaft 20 to move relative to the support inner shaft 70. Specifically, the connecting portion 632 of the deviation rectifying connecting member 63 is passed through the through hole 71 and is connected to the support shaft 20. The sliding portion 631 of the deviation rectifying connecting member 63 is fixedly connected to the connecting portion 632, and the sliding portion 631 is rotatably connected to the deviation rectifying transmission member 62. In this way, when the deviation rectifying transmission member 62 rotates, the sliding portion 631 of the deviation rectifying connecting member 63 can move relatively on the deviation rectifying transmission member 62, thereby driving the connecting portion 632 to move in the through hole 71, and further being able to drive the support shaft 20 to be axially movable relative to the base body 50, thus realizing the deviation rectifying action of the coil material.

[0065] Specifically, both ends of the deviation rectifying transmission member 62 are respectively supported on the deviation rectifying fixed seat 65.

The fixing connecting member can be one or more than two. Further, the fixing connecting members are uniformly distributed along the circumferential direction of the deviation rectifying fixed seat 65. The other end of the deviation rectifying transmission member 62 passes through the support inner shaft 70, and the deviation rectifying fixed seat 65 at this other end can be fixedly connected to the support inner shaft 70.

[0066] In some embodiments of the present utility model, referring to Figure 4 and Figure 5 , one of the support inner shaft 70 and the support shaft 20 is provided with a slide rail 72, the slide rail 72 is parallel to its axis, and the other is provided with a roller 21 that cooperates with the slide rail 72.

[0067] By providing the slide rail 72 and the roller 21, the friction between the support shaft 20 and the support inner shaft 70 is reduced, which is beneficial to the relative movement between the support shaft 20 and the support inner shaft 70; it should be noted that both the through hole 71 and the slide rail 72 are parallel to the axis of the support shaft 20, and in the axial direction of the support shaft 20, the extension length of the through hole is less than or equal to the extension length of the slide rail 72 to meet the dimensional requirements of the coil material deviation rectification and also avoid affecting the relative movement between the support shaft 20 and the support inner shaft 70, thereby improving the sliding stability between the support shaft 20 and the support inner shaft 70.

[0068] Specifically, the slide rail 72 can be provided on the support inner shaft 70. At this time, the roller 21 is provided on the support shaft 20; or, the slide rail 72 can be provided on the support shaft 20. At this time, the roller 21 is provided on the support inner shaft 70.

When the telescopic member 23 is in the contracted state, the support portion 22 is in the first position to avoid the coiled material, and when the telescopic member 23 is in the extended state, the support portion 22 is in the second position to support the coiled material.

[0071] By providing the support portion 22 that is movably connected to the support shaft 20 along the radial direction of the support shaft 20, the position of the support portion 22 can be adjusted to fix and release the coiled material, which is convenient for assembling and disassembling the coiled material and improves the installation stability of the coiled material.

[0072] Specifically, the support portion 22 can be in the shape of a point, a strip, an arc, etc. In the solution of this application, the support portion 22 is a key strip. The number of support portions 22 can be one or more than two.

[0076] By setting the telescopic member 23 as a flexible tube, inflating the flexible tube through the opening can make the flexible tube extend, and deflating can make the flexible tube contract. The structure is simple, the production cost is relatively low, and it is easy to operate. By providing the opening 24 on the support shaft 20 that is communicated with the opening, it is convenient to inflate the flexible tube through the opening 24.
