Description

Technical Field

[0001] This utility model relates to the field of belt conveyors, specifically to a belt conveyor support roller. Background Technology

[0002] Support rollers are key components of belt conveyors, serving to support the conveyor belt and ensure its smooth operation. For example, Chinese patent CN201520640898.9 provides a belt conveyor idler frame, including a base beam with side arms fixed at both ends; a pair of center frame ear mounting seats are fixed on the base beam, with center frame ears bolted to the mounting seats, and two idler mounting grooves on the center frame ears; side frame ears are bolted to the upper ends of the side arms. In such prior art idler structures, the belt needs to be bent at both ends during installation, and due to the belt's elasticity, it cannot effectively conform to the inclined idlers on both sides. Utility Model Content

[0003] The purpose of this invention is to provide a support roller for a belt conveyor, which solves the problem in the existing idler roller structure that the belt cannot effectively fit with the inclined idler rollers on both sides because the belt needs to be bent at both ends during installation and the belt has a certain degree of elasticity.

[0004] To achieve the above objectives, this utility model provides a belt conveyor support roller, which includes a base, two sets of first mounting frames are spaced apart in the middle of the base, and second mounting frames are respectively provided at both ends of the base. A horizontal roller is provided between the two first mounting frames, and an inclined roller is provided between the first mounting frames and the second mounting frames.

[0005] The second mounting bracket includes a vertical section disposed on the base, the end of the vertical section being inclined inward to form an inclined section, an adjustment frame being slidably disposed on the inclined section along its length direction, and a pressure roller being rotatably disposed on the adjustment frame, so that the pressure roller can approach or move away from the inclined roller.

[0006] Preferably, both the horizontal roller and the slanted roller include a shaft and a roller body rotatably mounted on the shaft;

[0007] The first mounting bracket and the second mounting bracket are respectively provided with U-shaped slots, and the two ends of the shaft are respectively engaged in the U-shaped slots.

[0008] Preferably, an arc-shaped clamp is provided at the U-shaped groove, and the arc-shaped clamp is locked at the U-shaped groove by screws to press the shaft into the U-shaped groove.

[0009] Preferably, the second mounting bracket has multiple screws on both sides, the adjusting bracket has an adjusting slot, and the screws pass through the adjusting slot and are engaged with locking nuts.

[0010] Preferably, the surface of the pressure roller is fitted with a rubber sleeve.

[0011] Preferably, the base has mounting seats at both ends, and the mounting seats have multiple mounting screw holes.

[0012] Beneficial Effects: This utility model provides a support roller for a belt conveyor. The support roller includes a base, two sets of first mounting frames spaced apart in the middle of the base, and second mounting frames at both ends of the base. A horizontal roller is positioned between the two first mounting frames, and an inclined roller is positioned between the first and second mounting frames. The second mounting frame includes a vertical section mounted on the base, with the end of the vertical section inclined inward to form an inclined section. An adjusting frame is slidably mounted on the inclined section along its length, and a pressure roller is rotatably mounted on the adjusting frame, allowing the pressure roller to move closer to or further away from the inclined roller. In practical use, the middle of the belt is supported by the horizontal roller, and both ends are supported by the inclined roller. Simultaneously, the two ends of the belt are pressed against the inclined roller by the pressure roller, preventing the belt from lifting due to elasticity at both ends, thus making the belt transport more stable.

[0013] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description
