Problems solved by technology
This method will not only increase the energy consumption and working time of the feeding device, but also reduce the production efficiency
[0005] In addition, the constant setting of the moving speed of the piston rod of the existing pneumatic buffer device
If the moving speed of the piston rod is set to be fast, when buffering the material with large mass, the impact of the material on the pneumatic buffer device will be great; but if the moving speed of the piston rod is set to be slow, when the buffer mass is large For small materials, the buffer efficiency is low

The invention discloses a pneumatic buffering device and a control method. The pneumatic buffering device comprises a cylinder, a supporting base and a control device, wherein the cylinder comprises acylinder body and a piston rod; the supporting base is arranged on the side corresponding to the first end of the cylinder body, and the first end of the cylinder body is provided with a rod cavity of the cylinder body; the supporting base is provided with a supporting hole, and the supporting hole and the piston rod are coaxially arranged; the piston rod is partially arranged in the supporting hole and is in sliding connection with the supporting hole; the control device is used for detecting the air pressure intensity of the cylinder body and the position information of the piston rod, andadjusting the moving direction and the moving speed of movement of the piston rod along the supporting hole according to the air pressure intensity and the position information. Due to the pneumatic buffering device and the control method, the pneumatic buffering device can bear the bending torque, the moving speed of the piston rod can be adjusted according to different kinetic energy of materials, so that the pneumatic buffering device adapts to materials in different sizes, at different falling points and with different kinetic energy, and the overall efficiency of the pneumatic buffering device is improved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of transportation equipment, in particular to a pneumatic buffer device and method. Background technique [0002] When the horizontal pneumatic buffer device is running, if the feeding device does not adjust the height of the material, when the size of the material is different, because the height of the center of mass of the material is different, the impact point on the piston rod is different. When the impact point deviates from the center of the piston rod , the piston rod will experience a bending moment. When the vertical pneumatic buffer device is in operation, if the position of the material falling point is uneven, the piston rod will also be subjected to a bending moment. [0003] Under normal circumstances, the cylinder is not allowed to bear the bending moment, because after the piston rod is subject to the bending moment, the piston rod is easily deformed, and an offse...
