Problems solved by technology
However, there are many factors that lead to the deviation of the belt, such as the unevenness of the fabric on the belt during transportation, the inconsistent degree of belt wear, and the quality problems of the belt itself, which will cause the belt to deviate.
Since the belt cannot automatically correct the deviation, if the deviation is not detected in time, the belt will directly rub against the frame, resulting in serious wear or tear of the belt until the belt is scrapped
Moreover, when the belt deviates, it is easy to cause the transported materials to scatter from one side and cause waste.

Embodiment Construction
[0011] From figure 1 It can be seen that the slider 2 located in the channel steel channel 1 of the belt conveyor bracket is connected to the screw 5 through the connecting rod 3 and the connecting sleeve 4, and the screw 5 is spirally connected with the inner sleeve 6 of the worm gear nut, and the worm gear reducer 7 and the reversible single-phase motor 8 are all connected on the tension counterweight box 9, and the left detection switch 13 and the right detection switch 14 are located at the edge of the belt 12 both sides.
[0012] figure 2 The principle is that when the power supply passes through phase line 16, left detection switch 13, motor winding one 18 to zero line 15, it also passes through motor winding two 19 to zero line 15 after moving to zero line 15 through commutation capacitor 17, so that the motor is rotated forward. When power supply passes through phase line 16, right detection switch 14, motor winding two 19 to zero line 15, also move to the rear throu...

The invention relates to an automatic correction device for a conveying belt, in particular to an automatic correction device of a conveying belt of a belt conveyor. The device is to solve the problems of serious belt wear or tear caused by belt deviation and waste caused by the scatter of conveyed materials from one side of the belt. For solving technical problems, the device adopts a technical scheme comprising: detecting the deviation situation of the belt (12) through detection switches (13 and 14); and then controlling the turning of a single-phase reversing motor (8) and pushing a screw(5) through a worm and gear reducer (7) to make a center line of a roller (11) vertical to that of the belt. The device has the advantage of automatically correcting the deviation of the belt when the belt conveyor works so as to prolong the service life of the belt and reduce the waste of the materials.
Description
technical field [0001] The invention relates to an automatic deviation correcting device for a conveying belt, in particular to an automatic deviation correcting device for a conveying belt of a belt conveyor. Background technique [0002] At present, the belt conveyors used in various industries all use ordinary lead screws to adjust the deviation of the belt. Repeated trials are required during adjustment, and they are fixed in this position after adjustment. However, there are many factors that cause the belt to deviate, such as the unevenness of the fabric on the belt during transportation, the inconsistent degree of belt wear, and the quality problems of the belt itself, which will cause the belt to deviate. Since the belt cannot automatically correct the deviation, if the deviation is not found in time, it will often cause the belt to directly rub against the frame, resulting in serious wear or tear of the belt until the belt is scrapped. Moreover, when the belt devia...
