Transportation structure for semi-finished wood

Abstract

The invention discloses a transportation structure for semi-finished wood. The transportation structure comprises a workbench, a pull wire and a rectangular frame. A belt winds around the rectangular frame, and the workbench is connected with the rectangular frame through a pulley block and the pull wire. A first air cylinder is arranged on the workbench. The pulley block is composed of four pulleys. Two of the four pulleys are arranged on the long edge of the side, close to the workbench, of the rectangular frame. The rest two pulleys are symmetrically arranged on the two sides of the output end of the first air cylinder with the axis of the first air cylinder as an axle. A pressure sensor is arranged at the tail of the output end of the first air cylinder. After the initial end of the pull wire is fixed to the workbench, the pull wire begins to wind around the four pulleys and the pressure sensor till the tail end of the pull wire is connected with the output end of a second air cylinder, and the pressure sensor is electrically connected with the first air cylinder and the second air cylinder. By means of the transportation structure, the situation that the transmission efficiency is reduced due to the tensity degree change of the belt or the working load of the belt is increased is avoided, and the working stability of a belt transmission machine is improved.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a transport structure for semi-finished wood. Background technique [0002] Belt conveyors generally include traction parts, load-bearing components, driving devices, tensioning devices, redirection devices and support parts, etc. The traction parts are used to transmit traction, and conveyor belts, traction chains or wire ropes can be used; the load-bearing components are used to hold materials. , There are hoppers, brackets or spreaders, etc.; the driving device provides power to the conveyor, and is generally composed of an electric motor, a reducer and a brake (terminator); the tensioning device generally has two types of screw type and heavy hammer type, which can be used The traction parts maintain a certain tension and sag to ensure the normal operation of the belt conveyor; the support parts are used to support the traction parts or load-bearing components, and rollers, rollers, etc. ca...

AI Technical Summary

Problems solved by technology

[0003] After the ordinary belt conveyor is used for a long time, the belt will slack to a certain extent, which will cause the center of gravity of the material on the belt to be unstable, or the transmission efficiency will drop sharply. At this time, the usual method is to use a tensioning device to tension the belt. The adjustment of the tension makes the belt return to the normal working level, but in the adjustment process of the tensioning device, the belt is generally pulled to increase the tension of the belt, and when the belt is pulled, the pull If the pulling force is not well grasped, the belt will be too tight, which will increase the working load of the belt conveyor. If the pulling force is too small, the belt will be too loose, and the transmission efficiency of the belt will be low.
