Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more particularly to an adjustable screw mechanism idler roller group for the transition section of a belt conveyor. Background Technology

[0002] Tubular belt conveyors are advanced and efficient material handling equipment with numerous advantages such as large conveying capacity, low energy consumption, high flexibility, and environmental friendliness, and are widely used in modern industrial production. The development of tubular belt conveyors can be traced back to the 1960s. Through years of research and practice, their technical performance has been continuously improved and optimized. Currently, they are widely used in ports, mines, power plants, coal mines, chemical plants, environmental protection, and other industries. The transition section, as an important component of the tubular belt conveyor, is mainly used to achieve a smooth transition between the straight and curved sections of the conveyor. The design of the transition section needs to consider multiple factors such as belt speed, conveying capacity, belt tension, and curve radius to ensure stable operation and extend the service life of the entire machine. Currently, many transition sections are designed with arc supports for angle adjustment. The disadvantages are numerous non-standard components, a small angle adjustment range, poor adjustment accuracy, and a serious impact on the service life of the belt conveyor, making it inconvenient for operators.

[0027] like Figures 1-5 As shown in the figure, this invention discloses an adjustable screw mechanism idler roller assembly for the transition section of a conveyor belt system. The assembly includes a central roller 1 and two side rollers 2 with adjustable rotation angles. The central roller is mounted on an idler beam. The two side rollers 2 with adjustable rotation angles are symmetrically arranged about the centerline of the central roller 1. The bottom of one end of each side roller 2 near the centerline of the central roller 1 is mounted on an idler bracket 3 via a first hinge pin. The other end is connected to a linkage mechanism. The linkage mechanism includes a push rod 8, a sliding support 9, a pin 7, and a second hinge pin connected to the side rollers. The push rod 8 is connected to the sliding support 9, and the pin 7 is positioned above the sliding support 9. The pin 7 is connected to the second hinge pin via a connecting rod 5. In this embodiment, the connecting rod 5 and the pin 7 are connected by a cotter pin 6.

[0028] Furthermore, the two ends of the middle roller 1 are engaged in the slots of the idler roller bracket 3. In this embodiment, the idler roller ends adopt a flattened structure to engage in the slots of the middle roller bracket.

[0029] The idler roller bracket 3 is welded with a stop 11, which is used to mechanically limit the sliding support.

[0030] The end of the side roller ear bracket 4 is bolted with a baffle 13, which is used to fix the side roller and prevent the side roller from falling off.

[0031] Furthermore, the middle roller 1 is disposed on the outside of the idler roller bracket 3, the idler roller bracket 3 is connected to the idler roller crossbeam, and the middle roller 1 and the two adjustable-angle side rollers 2 are staggered. In this embodiment, the three are arranged in a triangular structure.

[0032] Furthermore, the side roller 2 is mounted on the side roller ear bracket 4, and the side roller ear bracket 4 is connected to the first hinge shaft and the second hinge shaft. The first hinge shaft is disposed on the ear seat 12, and the bottom end of the ear seat 12 is fixedly connected to the roller support bracket.

[0033] The push rod 8 passes through the roller bracket and the large nut, forming a screw structure. The large nut cooperates with the push rod to form a screw structure, which can restrict the axial movement of the push rod when it rotates, converting the rotational motion into the linear motion of the sliding support.

[0034] Specifically, the sliding support is fitted onto the idler roller bracket, and the large nut 10 and the sliding support are connected in series by a push rod 8. The other end of the push rod 8 is fitted with a regular nut for fixing to the idler roller bracket 3. The sliding support can move linearly with the push rod and can also drive the connecting rod to move through the pin, realizing the transmission of force and the conversion of motion.

[0035] Generally, the angle of the side roller will remain for a certain period of time after the adjustment device is installed. As an extended implementation method, sliding friction is formed between the sliding support and the idler roller bracket. Therefore, when adjustment is required, it is necessary to prevent the two from getting stuck. Lubricant needs to be added to the connection between the two regularly to reduce frictional resistance.

[0036] Furthermore, the roller support is equipped with a dial, and when the sliding support moves on the crossbeam, the lifting angle of the side roller can be confirmed by the dial.

[0037] By rotating push rod 8 clockwise and counterclockwise, the sliding support 9 reciprocates, simultaneously causing connecting rod 5 to rotate passively. The connecting rod then pulls side roller 2 to rotate freely clockwise and counterclockwise around its fixed end, thus adjusting the tilt angle of side roller 2. The adjustment precision can be determined using the scale on the crossbeam to achieve the appropriate angle. After the adjustable screw mechanism roller group of the transition section is adjusted, the conveyor belt can operate normally.

[0038] Compared with existing mechanisms, this type of adjustable screw mechanism idler group for the transition section of the tube conveyor can replace the conventional transition idler group with a screw mechanism. This structure can reduce the difficulty and time of adjusting the angle, improve work efficiency, and simplify the overall tube forming performance of the tube conveyor.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
