The working principle is as follows: when the conveyor belt is used, firstly, the conveyor belt is moved to a position between a material to be conveyed and a material conveying end point through the universal wheels 14 arranged at the bottoms of the base 1 and the first base 13, and when the conveying length needs to be adjusted, for example; when the conveying length needs to be extended, firstly, the extension end of the hydraulic cylinder 2 is controlled to extend through the hydraulic station 9, so that the top surface of the extension end of the hydraulic cylinder 2 is attached to and pushes the transverse plate 3 to rise, at the moment, the transverse plate 3 can extrude the spring 8, the transverse plate 3 rises and simultaneously synchronously drives the U-shaped plate 25 and the first guide roller 26 arranged in the U-shaped plate to rise, so that the bottom of the first guide roller 26 is not tightened with the conveying belt 42, at the moment, the conveying belt 42 is in a loose state, at the moment, the extension end of the two first hydraulic cylinders 11 is synchronously controlled to extend through the hydraulic station 9, so that the extension ends of the two hydraulic cylinders 2 respectively push the two first bases 13 to move towards two sides through the first fixing plates 12, and because the conveying belt 42 is in a loose state, when the two first bases 13 move towards the two sides, the two rollers 18 at the tops of the two bases 18 cannot firmly, therefore, when the two rollers 18 move towards two sides along with the two first bases 13, the two rollers 18 cannot cause tensile force damage to the conveying belt 42, when the two first bases 13 move towards two sides, the two U-shaped mounting plates 16 can respectively pull the two chain mechanisms 37 to synchronously move, and simultaneously the two U-shaped mounting plates 16 can also pull the two second linear slide rails 33 synchronously, so that as the two first bases 13 move towards two sides, the second linear slide rails 33 and the first linear slide rails 30 can extend out of the linear slide rails 29, continuous bearing guide is provided for two ends of the chain shafts 38 of the pulled chain mechanisms 37, the bottom of the upper layer belt of the extension part of the conveying belt 42 can be always attached to the tops of the shaft sleeves 39 at the right lower ends of the upper layer belt, the extension part of the conveying belt 42 can play a supporting role, and meanwhile, the chain mechanisms 37 at the lower end of the extension part of the conveying belt 42 can bear the weight of products on the conveying belt 42, the bottom of the upper layer conveying belt 42 of the extending part is effectively prevented from being suspended, so that the phenomenon that the conveying belt 42 becomes loose under the weight of a product in the long-distance and long-time conveying process is avoided, the service life of the conveying belt 42 is effectively prolonged, when the distance between two rollers 18 reaches the conveying length needing to be extended, the first hydraulic cylinder 11 is stopped to extend continuously at first, then the extending end of the hydraulic cylinder 2 is controlled to descend, at the moment, the transverse plate 3 can synchronously drive a plurality of first guide rollers 26 to descend under the action of the spring 8 until the bottom of the first guide roller 26 is attached to the conveying belt 42 and the conveying belt 42 is tightened under the action of the spring 8, the hydraulic cylinder 2 is stopped to descend continuously, at the moment, if the conveying belt 42 is too tightly tightened by the first guide roller 26 under the action of the spring 8, the extending end of the hydraulic cylinder 2 can be properly controlled to extend a little distance, the flexible end of pneumatic cylinder 2 can withstand the dynamics of a part of spring 8 like this, can effectually slow down conveyer 42's the tight dynamics of stretching tightly and prevent conveyer 42 impaired, on the contrary, if conveyer 42 still can not be tightened by first guide roll 26 under the effect of spring 8, the flexible end decline some distance of control pneumatic cylinder 2 that can be appropriate, dog 5 can descend through the first guide roll 26 of diaphragm 3 lapse like this, thereby make first guide roll 26 tighten conveyer 42, and then avoid conveyer 42 lax operation. When the conveying length needs to be shortened, the telescopic ends of the two first hydraulic cylinders 11 are synchronously controlled to retract through the hydraulic station 9, so that the telescopic ends of the two first hydraulic cylinders 11 pull the two first bases 13 to approach each other, the two first bases 13 synchronously drive the two rollers 18 to approach each other, when the two first bases 13 approach each other, the two U-shaped mounting plates 16 respectively push the two chain mechanisms 37, and simultaneously the two U-shaped mounting plates 16 also synchronously push the two second linear slide rails 33, so that the second linear slide rails 33 and the first linear slide rails 30 extend into the linear slide rails 29, in the process, the chain mechanisms 37 still support the upper conveying belts 42 on the two sides of the mounting plate 24, when the distance between the two rollers 18 reaches the conveying length needing to be shortened, the continuous retraction work of the first hydraulic cylinders 11 is stopped, and because the two rollers 18 approach each other, at this moment, the conveying belt 42 is in a loose state, and at this moment, the descending distance of the telescopic end of the hydraulic cylinder 2 is controlled, so that the stop block 5 can downwards pull the first guide roller 26 to descend through the transverse plate 3, so that the first guide roller 26 tightens the conveying belt 42, and the purpose of tightening the conveying belt 42 is achieved.

After the conveying length is adjusted, the motor 17 is started, then the motor 17 can drive the roller 18 connected with the output shaft of the motor to rotate, the roller 18 thus drives the conveyor belt 42, and the conveyor belt 42 operates normally to deposit product onto the upper surface of the conveyor belt 42, the product is transported while moving along the conveyor belt 42, since the bottom of the upper conveyor belt 42 between the two mounting plates 24 is in abutment with the tops of the second plurality of guide rollers 28, and the bottom of the upper conveyor belt 42 between the mounting plate 24 and the roller drum 18 is attached to the top of the sleeve 39, therefore, the second guide roller 28 and the chain mechanism 37 can always effectively bear the weight of the products on the conveying belt 42, the conveying belt 42 is prevented from being loosened under the weight of the products in the long-distance and long-time conveying process, and the service life of the conveying belt 42 is effectively prolonged.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
