[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides two technical solutions:

[0026] Figures 1 - 5 The first embodiment is shown: A tubular conveyor automatic deviation correction device includes an outer frame 1 and a tubular conveyor belt 3. A deviation correction mechanism 2 is arranged inside the outer frame 1 for correcting the deviation of the tubular conveyor belt 3. The deviation correction mechanism 2 includes:

[0027] A guiding assembly 21, and the guiding assembly 21 includes an inner frame 211;

[0028] The correction component 22 includes a thrust bearing 221, a motor 223, and an electric push rod 227. The number of thrust bearings 221 is set to two, and they are respectively installed at the inner top and inner bottom of the inner frame 211. A connecting shaft 222 is rotatably provided at the end of the thrust bearing 221. A turbine 225 is fixedly sleeved on the outer surface of one of the connecting shafts 222. A worm 224 is meshed and connected to the outer surface of the turbine 225. The telescopic end of the electric push rod 227 is fixedly installed with a mounting bracket 228. A rotating shaft 229 is fixedly connected between the inner walls of the mounting bracket 228. A plurality of Mecanum wheels 2210 are fixedly sleeved on the outer surface of the rotating shaft 229. The Mecanum wheels 2210 are prior art. When the oblique rollers on the Mecanum wheels 2210 contact the tubular conveyor belt 3, an upward thrust is generated on the tubular conveyor belt 3, thereby correcting the deviation of the tubular conveyor belt 3.

[0029] A plurality of legs 11 are fixedly installed at the bottom of the outer frame 1. A lower guide roller support 213 is fixedly installed at a position near the bottom of the front surface of the inner frame 211. Four side guide roller supports 212 are fixedly installed on the rear surface of the inner frame 211. By setting the mutual cooperation of the lower guide roller support 213 and the side guide roller supports 212, a guiding effect on the tubular conveyor belt 3 is achieved.

[0030] Figures 1 - 5 The second embodiment is shown. The main difference from the first embodiment is that a connecting plate 214 is fixedly installed at a position near the top of the front surface of the inner frame 211. Slide rods 215 are symmetrically and movably penetrated through the top of the connecting plate 214. A bracket 216 is fixedly installed between the bottom ends of the two slide rods 215. A spring 217 is sleeved on the outer part of the slide rods 215. The two ends of the spring 217 are fixedly connected to the opposite sides of the connecting plate 214 and the bracket 216. An upper guide roller 218 is rotatably provided between the inner walls of the bracket 216. When the upper guide roller 218 contacts the tubular conveyor belt 3, the reverse elastic force generated by the compression of the spring 217 can increase the friction force between the guide roller and the tubular conveyor belt 3, thereby improving the efficiency of the deviation correction device. The inner frame 211 is fixedly connected between the opposite side ends of the two connecting shafts 222. The motor 223 is fixedly installed on the inner bottom of the outer frame 1. The output end of the motor 223 is fixedly connected to the end of the worm 224. A support frame 226 is fixedly connected to the outer surface of the electric push rod 227. The support frame 226 is fixedly installed on the front surface of the inner frame 211.

[0031] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] When the tubular conveyor belt 3 runs off track, the electric push rod 227 on the side where the belt has run off track is activated to push the Mecanum wheel 2210 into contact with the tubular conveyor belt 3. When the tubular conveyor belt 3 is conveying, under the action of the oblique force of the Mecanum wheel 2210, the tubular conveyor belt 3 is pushed upward to achieve the effect of rectifying the deviation. At the same time, by starting the motor 223 to drive the worm 224 to rotate, the turbine 225 is driven to rotate. When the turbine 225 rotates, it cooperates with the connecting shaft 222 to rotate on the thrust bearing 221, so that the inner frame 211 rotates, and then the tubular conveyor belt 3 restricted by the guide rollers can be brought back to the center line position. After the tubular conveyor belt 3 returns to the center line position, the inner frame 211 can be reset to the initial position. When the upper guide roller 218 contacts the tubular conveyor belt 3, the reverse elastic force generated by the compression of the spring 217 can increase the friction between the guide roller and the tubular conveyor belt 3, thereby improving the efficiency of the deviation rectifying device.
