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

Example Embodiment

[0020] Example 1

[0021] Such as figure 1 As shown, a belt 9 tension adjustment structure of the present invention includes an adjustment platform 1, a traction wire 3, a support frame 13, and a fence body 2. The adjustment platform 1 is connected to the fence body 2, and the belt 9 bypasses the fence body 2. The adjustment platform 1 is connected to the fence body 2 through a pulley block, a connecting rod 12 is provided on the support frame 13, the fence body 2 is slidably arranged on the connecting rod 12, and the adjustment platform 1 is provided with mutually connected air cylinders 4 And the baffle 5, a pressure sensor 6 is installed between the tail end of the cylinder 4 and the baffle 5, and the pressure sensor 6 is connected to the driving device of the cylinder 4 through a wire, the pulling wire 3 bypasses the pulley block, and the pulling wire 3 The two ends of the cylinder 4 are respectively fixed on the adjustment platform 1, and a roller 7 is installed on the tele...

[0022] Example 2

[0023] Such as figure 1 As shown, this embodiment is based on embodiment 1. The pulley set includes two first pulleys 10 and two second pulleys 11, and the two first pulleys 10 are installed on the fence body 2 close to the adjustment platform 1. On the side, a plurality of the second pulleys 11 are symmetrically arranged on both sides of the roller 7 with the axis of the cylinder as an axis. The first pulley 10 is connected to the second pulley 11 and the roller 7 through the traction line 3. The two first pulleys 10 are placed on the sides of the fence body 2, and the second pulley 11 is located on both sides of the roller 7. The roller 7 moves in the direction of the belt 9, and the two first pulleys 10 are driven by the traction line 3. Start to move towards the direction of the adjustment platform 1 to realize the slow and precise adjustment of the belt 9. When the roller 7 moves to a certain distance, the pressure sensor 6 between the cylinder 4 and the ...

[0024] Example 3

[0025] Such as figure 1 As shown, this embodiment is based on embodiment 1. The winding mechanism includes a motor 14 and a reel 15. The output end of the motor 14 is connected to the reel 15, and the end of the traction line 3 is connected to the reel 15 . When the first and the end of the traction wire 3 are fixed to the adjustment platform 1, during a long time of work, the traction wire 3 will loosen, which will further increase the distance of the cylinder 4 and increase the difficulty of adjusting the tension of the belt 9. The end of the traction line 3 is connected to the reel 15. The reel 15 will be driven by the motor 14 within a fixed period of time to recover the traction line 3, and the traction line 3 is adjusted to a certain extent to ensure the fence body during the whole work process. 2 Stability of movement.

Abstract

The invention discloses a regulating mechanism for stably regulating the tension of a carrier roller belt. The regulating mechanism comprises a regulating platform, a drawn wire, a supporting frame and a fence body. An air cylinder and a baffle which are connected with each other are arranged on the regulating platform. A pressure sensor is installed between the tail end of the air cylinder and the baffle. The pressure sensor is connected with a drive device of the air cylinder through a wire. An idler wheel is installed at the telescopic end of the air cylinder and connected with a pulley block through the drawn wire. A roller is rotationally arranged on the fence body. The regulating mechanism further comprises a winding mechanism arranged on the regulating platform. The start end of the drawn wire is fixed to the regulating platform and the tail end of the drawn wire is connected with the winding mechanism. The drawn line, similar to the belt is loosened after working for a long time and the air cylinder needs to move a longer distance to achieve the regulating function at this time. The loosened drawn wire can be tightened again through the winding mechanism arranged on the regulating platform, unnecessary output of the air cylinder is reduced, and meanwhile fine regulating efficiency of the air cylinder to the belt is improved.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to an adjustment mechanism for stably adjusting the tension force of the idler belt. 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 compo...
