[0020] As Figures 1-4 shown:

[0021] This embodiment provides an automatic deviation-correcting knife-edge belt, which includes a conveying table 100. The conveying table 100 is used to limit and support the material transmission shaft 102 and support the deviation-correcting assembly 110. A slot 101 is provided on the conveying table 100. The slot 101 is used to place the conveyor belt 104. The conveyor belt 104 is used to convey materials. A transmission shaft 102 is rotatably arranged in the slot 101. The transmission shaft 102 is used to drive the conveyor belt 104 to rotate. A roller 103 that rolls horizontally is rotatably arranged on the transmission shaft 102. The roller 103 is used to reduce the friction between the conveyor belt 104 and the transmission shaft 102 when the conveyor belt 104 is moved left and right, so that the conveyor belt 104 can move left and right better and is more easily corrected for deviation. The conveyor belt 104 is rotatably arranged on the roller 103. Multiple groups of deviation-correcting assemblies 110 for correcting the deviation of the conveyor belt 104 are symmetrically arranged on the conveying table 100.

[0022] A plurality of grooves 105 are circumferentially and integrally arranged on the transmission shaft 102. The grooves 105 are used to limit the roller 103, so that the roller 103 can rotate in the grooves 105 and reduce the distance between the conveyor belt 104 and the transmission shaft 102, preventing the distance from being too large and causing the conveyor belt 104 to fall off. The roller 103 is rotatably arranged in the grooves 105.

[0023] A connecting rod 106 for limiting the roller 103 is connected to the center position of the roller 103. Both ends of the connecting rod 106 are fixedly connected and arranged in the grooves 105.

[0024] The deviation correction component 110 includes a bracket 111 symmetrically arranged on the conveying platform 100. The bracket 111 is fixedly arranged on the conveying platform 100 by bolts. The bracket 111 is used to connect the conveying platform 100 and the photoelectric sensor 112. The photoelectric sensor 112 is fixedly connected to the bracket 111. The photoelectric sensor 112 used in the utility model is a slot-type photoelectric sensor 112. When in use, a light emitter and a receiver are mounted face to face on both sides of a slot. The slot-type photoelectric sensor. The light emitter can emit infrared light or visible light, and the light receiver can receive light without obstruction. However, when the object to be detected passes through the slot, the light is blocked and the photoelectric switch is activated. A switch control signal is output, and the toggle component 120 is used to toggle the conveyor belt 104 that blocks the light source so that the light receiver can receive the light, thereby completing a control action. The photoelectric sensor 112 is used to detect whether the conveyor belt 104 is displaced. The photoelectric sensor 112 is arranged on both sides of the conveyor belt 104. The bottom of the groove 105 is provided with a toggle component 120 used in conjunction with the photoelectric sensor 112. The toggle component 120 is used to reset the offset conveyor belt 104.

[0025] The toggle assembly 120 includes a two-way cylinder 121 arranged at the bottom of the groove 105, and the two-way cylinder 121 is fixedly arranged at the bottom of the groove 105 of the conveyor platform 100. The two-way cylinder 121 is used to drive the limit rod 123 to move toward each other. The output end of the two-way cylinder 121 is connected to a roller 122, and the roller 122 is used to fit the edge of the conveyor belt 104 and during the rotation of the conveyor belt 104, the roller 122 can be used to roll with the rotation of the conveyor belt 104 to prevent damage to the side of the conveyor belt 104. The roller 122 is arranged on both sides of the conveyor belt 104, and the output end of the two-way cylinder 121 is fixedly connected with a limit rod 123. The limit rod 123 is used to limit the roller 122 and drive the roller 122 to move, and the roller 122 is rotatably arranged on the limit rod 123.

[0026] Working principle: When in use, connect the photoelectric sensor 112 and the double-acting cylinder 121 to the PLC control cabinet, and then start the transmission shaft 102. Use the transmission shaft 102 to drive the conveyor belt 104 to rotate, so that the conveyor belt 104 conveys. When the conveyor belt 104 is offset on the transmission shaft 102 and the conveyor belt 104 deflects to one side, the photoelectric sensor 112 is interfered and gives a signal feedback. Then start the double-acting cylinder 121, and use the output end of the double-acting cylinder 121 to drive the limit rod 123 to move. The limit rod 123 drives the roller 122 to fit against the side of the conveyor belt 104 to center the conveyor belt 104. When the roller 122 drives the conveyor belt 104 to move closer to the middle, the inner side of the conveyor belt 104 contacts the roller 103. When the roller 122 drives the conveyor belt 104 to move to one side, the inside of the conveyor belt 104 contacts the roller 103, which can effectively reduce the friction force and facilitate the left and right swing of the conveyor belt 104.
