Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a roller device for preventing belt deviation. Background Art

[0002] Belt conveyors are usually composed of belts, rollers, idlers, steel structures and other parts. The rollers, idlers and belts of belt conveyors all have smooth surfaces. They are sleeved on the surface of the idlers and driven by the driving device to drive the belts to transport the materials. However, during the operation of the belts, they may deviate, causing material leakage and affecting the transportation efficiency.

[0003] In the prior art, a belt conveyor that is not prone to deviation is disclosed in announcement number CN 217497466 U, which belongs to the technical field of belt conveyor equipment and is used to prevent the belt from deviating. Its technical solution is as follows: the lower surface of the belt has a raised positioning strip, which runs along the length of the belt; the upper surfaces of the idlers and the drum respectively have positioning grooves, which surround the circumferential surfaces of the idlers and the drum; the depth and width of the positioning grooves on the upper surfaces of the idlers and the drum respectively match the height and width of the positioning strip on the lower surface of the belt; the positioning strip on the lower surface of the belt is respectively embedded in the positioning groove on the upper surface of the idlers and the drum. The utility model has a simple structure and is easy to use. When the belt is subject to external interference and is about to deviate, the positioning strip on the bottom surface of the belt is stuck in the positioning groove of the idler and the drum, which can restrain the belt laterally, prevent the belt from lateral movement, and keep the belt in a stable straight-line running state, fundamentally solving the problem of belt deviation in belt conveyors.

[0004] The above-mentioned device realizes lateral constraint of the belt by opening a positioning groove on the roller and utilizing the cooperation of the positioning strip and the positioning groove. However, if the depth of the positioning groove is too large, the structural strength of the roller will be destroyed. If the depth of the positioning groove is too small, the positioning strip will easily detach from the positioning groove, and the belt cannot be properly constrained laterally, so it cannot meet actual needs. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a roller device for preventing the belt from deviating.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A roller device for preventing a belt from deviating is designed, comprising a roller frame, a horizontal roller arranged in the middle of the roller frame, inclined rollers located on both sides of the horizontal roller, a bracket connecting the horizontal roller and the inclined roller, and a belt laid on the horizontal roller and the inclined roller, wherein the belt has a curved section, an extension plate is provided at the bottom of the curved section, a mounting plate is provided at the top of the bracket, and the length extension directions of the mounting plate and the extension plate are perpendicular to each other, wherein the mounting plate is provided with a deviation correction component for resetting the extension plate.

[0008] Furthermore, the correction assembly includes a limit plate abutting against both sides of the extension plate, a cross bar connected to the limit plate, a torsion spring provided on the mounting plate, and a reinforcement rod connecting the torsion spring and the cross bar.

[0009] Furthermore, the correction assembly also includes a first pull rod hinged to the reinforcement rod, a first sliding groove opened at the end of the first pull rod, a first sliding rod slidingly matched with the first sliding groove, a first spring connecting the first sliding rod and the bottom of the first sliding groove, and a second pull rod connected to the first sliding rod.

[0010] Furthermore, the distance from the hinge point between the first pull rod and the reinforcement rod to the cross rod is 1 / 5-1 / 4 of the length of the reinforcement rod.

[0011] Furthermore, the correction component also includes a positioning seat arranged on the mounting plate, a second sliding groove opened on both sides of the positioning seat, a second sliding rod arranged in the second sliding groove and hinged to the second pull rod, a second spring connecting the second sliding rod and the bottom of the second sliding groove, and a ball arranged between the second sliding rod and the inner wall of the second sliding groove.

[0012] Furthermore, an elastic plate is provided at the bottom of the mounting plate.

[0013] The utility model proposes a roller device for preventing the belt from deviating. The beneficial effect is that when the belt is about to deviate, the extension plate at the bottom of the curved section can limit the lateral movement of the belt under the reset of the deviation correction component, thereby preventing the belt from moving laterally and keeping the belt in a stable straight running state, thereby achieving the anti-deviation effect of the belt and significantly improving the stability of the belt operation.

[0014] The utility model can provide elastic restoring force to the limit plate through the cooperation of the torsion spring, the reinforcement rod and the cross bar. When the belt deviates to the side, the elastic force of the torsion spring can push the limit plate and drive the extension plate to reset, thereby achieving the effect of preventing the belt from deviating and improving the stability of the belt operation.

[0015] The first pull rod of the utility model moves along with the reinforcement rod, so that the first spring is stretched, thereby providing elastic restoring force to the first pull rod, and further providing elastic restoring force to the limit plate;

[0016] The first pull rod and the second pull rod of the utility model move with the reinforcement rod, driving the second slide rod to move in the second slide groove. The second spring is stretched, providing elastic restoring force to the first pull rod and the second pull rod, and further providing elastic restoring force to the limit plate.
