Background
The pipe belt conveyor takes the conveying belt as a traction and bearing part and drives the conveying belt to operate through friction transmission, thereby realizing the continuous conveying of materials. The round section of the pipe belt conveyor is formed by forcing the conveying belt to be rolled into a round pipe shape by the polygonal carrier roller group arranged at a certain interval, and conveying materials are sealed in the round pipe to run along with the rubber belt, so that the environmental pollution is reduced, and the environment-friendly conveying is realized.
In the actual operation process of the pipe belt conveyor, due to the influences of factors such as installation accuracy errors, material loading eccentricity, external disturbance and the like, the conveying belt may deviate and twist, if the serious accidents such as accelerated abrasion of a carrier roller, material scattering, belt overlapping and tearing of the conveying belt can be caused by timely correction, so that a twisting automatic deviation correcting device is adopted, and deviation correcting measures are immediately taken when the pipe belt conveyor slightly twists.
In the prior art, a pipe belt conveyor mainly depends on a sensor to detect the torsion of a tubular rubber belt to realize automatic deviation correction, and a motor is used for driving a gear to rotate to drive a carrier roller to perform deviation correction. There are mainly three schemes:
according to the first scheme, whether a calibration object deviates from a vertical center position is detected through a detection module, and then a feedback signal controls all carrier rollers on the circular tube carrier roller module to rotate in the opposite direction, so that a conveying belt returns to an original position;
the second scheme is that a fixed CCD sensor (charge coupled device image sensor) is adopted, image processing is carried out by a computer to identify the position of the adhesive tape, and a motor is controlled to drive a carrier roller at the lowest part of the carrier roller group to deflect;
and thirdly, acquiring the position of the outer surface of the adhesive tape by using a gyroscope, judging whether the overlapping opening of the adhesive tape deviates or not, and controlling a carrier roller at the lowest part of the carrier roller group to rotate and correct the deviation.
The optical element, the gyroscope and the like are adopted to identify the twisting of the adhesive tape, then the control module sends out a control signal to drive the motor to rotate, and the motor controls one or more carrier rollers to deflect the angle, so that the automatic deviation correction is completed. Due to the arrangement, the whole system must adopt the motor as a driving energy source, and the operation of the driving deviation correcting device can be ensured only by inputting a power supply from the outside. In practical application, in most application environments, electricity is very inconvenient to get along the pipe belt conveyor, meanwhile, the device gets electricity from the outside, the danger of electric shock and electric leakage of maintainers on the pipe belt conveyor is improved, and the device is easy to lose efficacy and low in reliability due to the fact that the device is required to be equipped with a motor, a power supply and the like, and is used outdoors for a long time.

The photosensor 51 may be a photo sensor that can pass infrared light, a pair of tubes, or the like, and is not particularly limited herein. Alternatively, in this embodiment, whether the adhesive tape 2 is twisted and the twisting direction thereof may be detected by other detecting components, such as a gyroscope.
In addition, the deviation correcting device further comprises a controller 8, the controller 8 is in signal connection with the detection device and the reversing mechanism, the detection device can send the detection result to the controller 8, and the controller 8 can send a driving signal to the reversing mechanism according to the twisting direction of the adhesive tape 2, so that the second gear 642 is meshed with the corresponding first gear 641, and the deviation correcting roller 41 rotates around the rotating shaft and acts on the adhesive tape 2 to rotate to the original position. Specifically, the controller 8 includes a single chip microcomputer and a power circuit, and how to connect the controller 8 to the detection device and the reversing mechanism through signals is well known in the prior art, and is not described herein again for brevity.
When the adhesive tape 2 is not twisted, the identification tape 21 is positioned between the two photosensitive sensors 51, at this time, the infrared signal emitted by the photosensitive sensors 51 is absorbed when encountering the natural color surface of the adhesive tape 2, the detection device outputs high level, and the controller 8 does not send out a driving signal; when the adhesive tape 2 is twisted, taking clockwise twisting of the adhesive tape 2 as an example, the identification tape 21 deflects to the right, at this time, an infrared signal of the photosensor 51 positioned on the right encounters the identification tape 21 to generate signal reflection, the detection device outputs a low level to the controller, the controller 8 judges that the adhesive tape 2 is twisted clockwise and sends a driving signal to the reversing mechanism, and the reversing mechanism acts on the transmission shaft 62 to enable the second gear 642 to be meshed with one first gear 641 and enable the rectification roller 41 to rotate counterclockwise, so that rectification force is generated on the adhesive tape 2, and the adhesive tape 2 can return to a normal operation position.
When the adhesive tape 2 returns to the normal operation position (home position), the controller 8 sends a signal to the reversing mechanism to make the second gear 642 return between the two first gears 641 and disengage from the first gears 641, and at this time, the deviation rectifying roller 41 will return to the home position under the action of the torsion spring.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
