Description

Technical Field

[0001] The utility model relates to the technical field of plate transportation, in particular to a roller conveyor device for transporting special-shaped plates. Background Art

[0002] In the boom plate grinding automatic line in the large excavator production line, it is necessary to transport large special-shaped plates such as boom plates and hinge plates after flame cutting. The existing general transport rollers only consider their carrying and transportation capabilities. Although the power is sufficient, the gap between the workpiece and the ideal is too large. The actual workpiece is a blank. The parallelism deviation of the plate flame-cut according to this length is very large, up to ±10mm. There will be a lot of slag, weld nodules and burrs along the edge, so jamming often occurs during transportation. The reason is not insufficient power, but insufficient friction between the roller and the special-shaped iron plate, poor parallelism of the iron plate, and slag on the surface. If you are not careful, the workpiece will rub against other related structures, resulting in jamming. Utility Model Content

[0021] The utility model of the special-shaped plate roller conveyor device comprises Figures 1 to 4 As shown, it includes a roller support frame 2, a reduction motor 5, a chain 6, a sprocket 7, a transmission shaft 8, a bevel gear 9, a steel roller 11 and a rubber-coated roller 12. The sprocket 7, the transmission shaft 8 and the bevel gear 9 are arranged on one side of the roller support frame 2. The steel rollers 11 and the rubber-coated rollers 12 alternately form a transport roller arranged on the roller support frame 2. The output end of the reduction motor 5 is connected to the sprocket 7. The chain 6 is sleeved on the sprocket 7. The chain 6 is a double chain. The sprocket 7 is connected to the transmission shaft 8. The sprocket 7 is used to drive the steel roller 11 and the rubber-coated roller 12 to rotate. There are multiple bevel gears 9 and they are arranged on the transmission shaft 8. One end of each steel roller 11 and the rubber-coated roller 12 is correspondingly connected to a bevel gear 9, and the other end of the steel roller 11 and the rubber-coated roller 12 is connected to a quick-change mechanism.

[0022] There are at least two steel rollers 11 and at least one rubber-coated roller 12, and the interval between the steel roller 11 and the rubber-coated roller 12 is at least 300 mm.

[0023] A protective cover 4 is provided on one side of the roller support frame 2 on which a transmission shaft 8 is provided. The protective cover 4 is fixedly connected to the roller support frame 2 through a protective connecting rod 20. The protective cover 4 is used to protect the chain 6, sprocket 7, transmission shaft 8 and bevel gear 9.

The surface of the rubber-coated roller 12 is provided with a polyurethane rubber coating with a hardness of HS75-90 on the Shore A hardness, which can effectively reduce the situation of roller jamming. The rubber-coated roller 12 brings friction power to offset the resistance caused by the slag and weld nodules on the special-shaped plate workpiece 1, and the protruding slag weld nodules, under the action of the rubber-coated roller 12, become the benefit of increasing the rolling friction. The connection structure between the two ends of the steel roller 11 and the roller support frame 2 is the same as the connection structure between the two ends of the rubber-coated roller 12 and the roller support frame 2.

[0025] Depend on Figure 7As shown, it also includes a fastening nail 19. Screw holes are provided on both sides of the connection between the bevel gear 9 and the steel roller 11 and the rubber-coated roller 12.

The transport roller is powered by the reduction motor 5, and the power is transmitted to the transmission shaft 8 through the sprocket 7 and the chain 6. The transmission shaft 8 drives the bevel gear 9 connected to the steel roller 11 and the rubber-coated roller 12, thereby driving the steel roller 11 and the rubber-coated roller 12 to rotate.

[0028] The utility model discloses a special-shaped plate transport roller conveyor, which forms a transport roller conveyor by alternately arranging steel rollers and rubber-coated rollers, thereby effectively increasing the friction force of the roller conveyor on the special-shaped plate workpiece and preventing the material from being stuck during transportation. A quick-change mechanism is provided to quickly replace damaged steel rollers and rubber-coated rollers.
