[0003] The conveyor belt of the inclined belt conveyor is made of flexible nylon, canvas, polyester, and rubber materials cast at high temperature. Under the combined action of driving force and tension, the transport section and the return section both show linear motion through the inflection point of the inclined angle. Figure 1 As shown, there is a design standard of a pressure roller a at the turning point of the transport section (the pressure roller can be seen in the patent number CN203345579U), the purpose of which is to ensure that the conveyor belt b maintains lateral static friction with the upper roller c when transporting materials, so as to ensure that the conveyor section does not deviate or run away. However, there is no pressure roller design in the return section, and the conveyor belt b is suspended when passing the return turning point, and cannot maintain lateral static friction with the lower roller d, causing the return belt to be unable to adjust, and there is an irregular phenomenon of random deviation on the A side (drive device side) and the B side (non-drive device side), resulting in torn edges and wear of the conveyor belt, which greatly shortens its service life.

The bottom of the screw is fixedly connected to the transverse plate, the U-shaped shell is fixed to the bottom of the transverse plate, the rotating shaft of the lower pressure pulley is mounted on the transverse plate, and the angle adjustment mechanism is arranged between the transverse plate and the U-shaped shell.

[0008] Furthermore, the locking assembly comprises an upper locking nut and a lower locking nut, and the upper locking nut and the lower locking nut are respectively threadedly connected to the screws on the upper and lower sides of the U-shaped frame.

[0009] Furthermore, a slide rail is provided inside the frame of the inclined belt conveyor, a slider is provided on the side of the U-shaped shell away from the pressure pulley, the slider is slidably mounted on the slide rail, and the slider is connected to the transverse plate.

[0010] Furthermore, both ends of the slide rail are open structures.

[0013] Beneficial Effects

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The adjustable belt pressing device of the utility model can press the conveyor belt in the return section by arranging two downward pressing pulleys in the return section of the conveyor belt of the inclined belt conveyor, so as to ensure that the conveyor belt runs smoothly during the return journey, so as to ensure that the conveyor belt does not deviate and run away, and can effectively prevent the conveyor belt from deviating during the return journey and extend the service life of the conveyor belt.

[0016] 2. The adjustable belt pressing device of the utility model can randomly adjust the height of the lower pressure pulley by arranging a height adjustment mechanism and an angle adjustment mechanism for adjusting the height and inclination angle of the lower pressure pulley on the inclined belt conveyor, so as to ensure that the conveyor belt maintains lateral static friction with the lower roller during the return journey. At the same time, the conveyor belt return deviation can be adjusted according to the conveyor belt "running high but not low" rule.

[0028] The adjustable belt pressing device of the present embodiment can adjust the height and inclination angle of the lower pressure pulley 1 by arranging a height adjustment mechanism and an angle adjustment mechanism on the inclined belt conveyor 2, so as to randomly adjust the height of the lower pressure pulley 1 to ensure that the conveyor belt maintains lateral static friction with the lower roller during the return journey, and can also adjust the return deviation of the conveyor belt according to the conveyor belt "running high but not low" rule.
