[0001] The utility model relates to the technical field of roller conveyor lines, in particular to a roller conveyor line which is convenient for height adjustment. Background Art

[0002] Roller conveyor line is a common material conveying equipment, usually used for material handling and transportation in industrial production. It consists of multiple rollers that can rotate to transport materials from one location to another. Roller conveyor line can be used to transport various types of materials, such as boxes, bagged materials, bulk materials, etc.

[0003] The legs of some existing roller conveyor lines are usually integrated. When adjusting the height of the conveyor line, it is necessary to first turn the bolts, remove the legs, and then install legs of appropriate length, which is rather troublesome. In addition, after such roller conveyor lines have been used for a period of time, the conveyor rollers need to be maintained. At this time, the surface of each conveyor roller needs to be wiped manually, which is rather troublesome.

[0004] Therefore, those skilled in the art provide a roller conveyor line that is convenient for height adjustment to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a roller conveyor line which is convenient for height adjustment.

By setting a cleaning mechanism, the surfaces of multiple conveyor rollers can be cleaned at the same time, and there is no need to manually wipe the surface of a single conveyor roller in turn, which is more convenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller conveyor line with convenient height adjustment, comprising a supporting mechanism, a first transverse plate, a plurality of conveying rollers and a cleaning mechanism, the supporting mechanism comprising two H-shaped plates, four extrusion plates, two limit plates, two support plates and a rotating rod, a return spring is fixedly arranged between the end surfaces of the four extrusion plates on one side opposite to each other, a lifting plate is slidably arranged through the upper surfaces of the two H-shaped plates and the two support plates, a first screw rod is rotatably arranged through the inner bottom surfaces of the two support plates, a first bevel tooth is arranged on the lower side of an outer end surface of the rear side of the two first screw rods, a second bevel tooth is arranged on the front side of the outer end surface of the rotating rod, and a belt is connected between the lower sides of the outer end surfaces of the two first screw rods;

[0007] The cleaning mechanism includes a slider, a second screw rod, two first L-shaped plates, multiple second L-shaped plates and multiple third L-shaped plates, the multiple second L-shaped plates are all slidably provided with a second semicircular plate on the rear side of the outer end faces, and the multiple third L-shaped plates are all slidably provided with a first semicircular plate on the front side of the outer end faces.

[0008] Through the above technical scheme, the two extrusion plates are manually pulled toward the middle, and when the two extrusion plates do not block the limit plate, the limit plate is held and moved upward, and the pulling of the two extrusion plates is released at this time. Under the action of the reset spring, the limit plate is fixed in the air, and then the same operation is performed on the other two extrusion plates, and finally the rotating rod is rotated, and the two first screw rods are driven to rotate together through the connection between the first bevel gear and the second bevel gear, and the belt between the two first screw rods. During the rotation, the two first screw rods drive the lifting plate to move upward, and the second screw rod is manually rotated for a distance. At this time, the second semicircular plate can be held and moved to the rear side. After a back and forth trip, the second screw rod continues to be rotated. After rotating for a distance, the slider is held and moved to one side. When it cannot move, the second screw rod is turned back to the previous position. Finally, the second semicircular plate is held and moved to one side, and the surface of other conveying rollers can be cleaned.

[0009] Further, the first transverse plates are fixedly arranged between the three front sides of the lifting plates, the second transverse plates are fixedly arranged between the three rear sides of the lifting plates, the conveying rollers are rotatably arranged between the end faces of the first transverse plates and the second transverse plates on opposite sides, the inner bottom surface of the second transverse plates is fixedly arranged with a motor, and the output end of the motor is fixedly connected to one side of the conveying rollers;

[0011] Further, the four extrusion plates are slidably connected to the two H-shaped plates in pairs, the two limit plates are slidably connected to the two H-shaped plates in pairs, and the plurality of lifting plates are fixedly connected in pairs through a first connecting plate;

[0012] Through the above technical solution, the two extrusion plates are held against by the limiting plate, so that after the two extrusion plates are pulled, the extrusion plates can be simply fixed, which is convenient for other operations.

[0013] Furthermore, the rotating rod penetrates and is rotatably arranged on the lower side of a rear end surface of the two support plates, and the first bevel gear is meshed and connected with the second bevel gear;

[0014] Through the above technical solution, by rotating the rotating rod, the rotating rod drives the second bevel gear to rotate, and during the rotation process, drives the first bevel gear to rotate, thereby driving the first screw rod at the rear side to rotate.

[0020] Through the above technical solution, when the second screw rod is rotated to the first gear, the multiple second L-shaped plates and the multiple third L-shaped plates do not abut against the end faces of the multiple first semicircular plates and the multiple second semicircular plates respectively, and the second semicircular plate at the upper end can be moved at this time.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a roller conveyor line with convenient height adjustment. The two extrusion plates are manually pulled toward the middle. When the two extrusion plates do not block the limit plate, the limit plate is held and moved upward, and then the pulling of the two extrusion plates is released. Under the action of the reset spring, the two extrusion plates are against the limit plate, so that the extrusion plates are fixed. Then the same operation is performed on the other two extrusion plates. Finally, the rotating rod is rotated. The rotating rod drives the first screw rod on the rear side to rotate through the connection between the first bevel gear and the second bevel gear. The first screw rod on the rear side drives the first screw rod on the front side to rotate together through the belt. At this time, the height of the conveyor line can be adjusted, which is more convenient.

[0023] 2. The utility model proposes a roller conveyor line with convenient height adjustment. The second screw rod is manually rotated to the first gear. At this time, the second screw rod drives the two first L-shaped plates to move a distance in opposite directions. After the second screw rod stops rotating, the second semicircular plate on the upper side is held and moved backward. After one back and forth movement, the second screw rod is rotated to the second gear. Multiple second semicircular plates and multiple first semicircular plates move in opposite directions. At this time, the slider is held and moved to one side. When it cannot move, the second screw rod is turned back to the first gear. Finally, the second semicircular plate is held and moved to one side again. By setting a cleaning mechanism, the surfaces of multiple conveying rollers can be cleaned at the same time, and there is no need to manually wipe the surface of a single conveying roller in turn, which is more convenient.
