Transmission mechanism of rotational moulding machine

Abstract

The invention provides a transmission mechanism of a rotational moulding machine. The transmission mechanism comprises a base, two first bearing blocks, four tensioning wheels, a second bearing block, a first transmission part and a second transmission part. The two first bearing blocks are arranged above the base. Driven shafts are contained in the first bearing blocks, and driven wheels are arranged at the tail ends of the driven shafts. The four tensioning wheels are arranged on the side of the base. A drive shaft is contained in the second bearing block, and a drive wheel is arranged at the tail end of the drive shaft. The first transmission part is wound on the drive wheel, the driven wheel and one tensioning wheel. The second transmission part and the first transmission part share the tensioning wheel and are wound on the other three tensioning wheels and the driven wheels. The transmission parts are designed as two independent structures and are abutted to the four tensioning wheels mutually, so that deformation of the transmission parts is prevented, and noise is lowered. The transmission parts in fine deformation can be adjusted in terms of position by an adjusting bolt arranged on a boss, and accordingly the transmission parts can be reliably wound on the drive wheel, the driven wheels and the tensioning wheels, and stability of the transmission mechanism of the rotational moulding machine is increased.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a transmission mechanism of a rotational molding machine. Background technique [0002] Rotational molding is a process method for forming large hollow storage tanks. Rotational molding is to add resin powder into the rotational molding mold, then heat the rotational molding mold and make it rotate continuously along two parallel axes, the resin in the rotational molding mold is gradually and evenly coated and melted under the action of gravity and heat Adhere to the inner surface of the rotational molding mold to form the desired shape of the storage tank, then cool the mold and demould to obtain the storage tank. [0003] At present, large-scale hollow storage tanks are generally manufactured through a rotational molding process on a rotational molding machine. Due to the huge size and weight of the rotomolding machine, it is usually more than ten meters or even tens of meters ...

AI Technical Summary

Problems solved by technology

The transmission mechanism of the rotomolding machine with this structure will wear out after a long time of use, resulting in the length of the chain being elongated, and the elongated chain will emit extra noise during the transmission process.

Because the volume of the rotational molding machine is huge, the chain is also very long, so the phenomenon of the chain being stretched will be more obvious

At the same time, only one chain is usually set in the transmission mechanism of the rotomolding machine in the prior art. Once it is tempered, the two driven shafts will stop rotating, which will seriously affect the working efficiency of the rotomolding machine.
