Background A stopper is a device for assisting in controlling the position of a stop for transporting goods on a transport line. When the turnover box is conveyed at a high speed on a conveying line, the inertia is large, if the turnover box is normally stopped, the box stopping positions are different according to the weight difference of the goods loaded by the turnover box, and some cases need to be accurately stopped at the designated positions of the conveying line, for example, the positions of transfer machines on the conveying line, and all cases need to be accurately stopped, so that a stopper device is needed to be used, and when the turnover box in high-speed conveying needs to be accurately stopped on a stacking station, the stopper is needed to assist the turnover box to be stopped. The power source of the stopper used in the existing project is an air cylinder, the factory with high safety level is in consideration of safety in the factory, the air source is not installed in the factory, and the air pump is not allowed to be used in the factory, so that the stopper cannot be used without the power source. Under the condition that an air source can be used, the lifting speed and the action beat of the stopper are transitionally dependent on the stability of the air source pressure, and the control method of the stopper cannot meet the requirement of a high-speed conveying line, so that the action of the stopper is not controlled accurately during high-speed conveying. The high-speed conveyor of most warehouse conveying equipment manufacturers has few projects, the use scene of the stopper is used on the non-high-speed conveyor, the control method can be used during non-high-speed conveying, and the cylinder is used as a power source, so that the cost is low, and the maintenance is convenient. The conveying beat is fast when conveying at high speed, the stopper needs to run at high speed, at the moment, the stopper using the air cylinder as power is used again, the stopper acts on the beat block, the stability cannot be guaranteed, and the control method cannot meet the requirement that the stopper is applied to a high-speed conveying line.
