Rotational moulding machine

Abstract

The invention relates to a rotational moulding machine which mainly comprises a bracket system, a heating system, a heating chamber and a rail, wherein the heating system is adjacent to the heating chamber and is composed of an oven wall, a front lateral door, a rear lateral door and a bottom baffle; a mould and a driving system for driving the mould to rotate around double shaft are arranged in the bracket system; the height of the mould is adjustable; the heating system is arranged on the side wall of the oven wall and comprises a combustion engine, an air inlet, an air flue, a circulating fan and an air outlet; and the air flue and the heating chamber are integral. On the basis of the integrated design of arranging the freely moving bracket system, fully sealing the periphery of the heating chamber and arranging the air flue with the heating chamber, the heat loss is reduced, the molding efficiency is increased, the energy consumption is reduced, and an independent bottom rotating mechanism is strong in bearing capacity. The working position of the mould is adjusted according to the size and quantity of the mould. A heat conducting chip is arranged between the air inlet and air outlet of the heating chamber, so that the quick heating and uniform heating of the mould are efficiently ensured and the total heat conveyed by the heating chamber is increased.

Description

technical field [0001] The invention relates to the technical field of rotomolding, in particular to a fully enclosed rotomolding machine with a rotary chassis, which is suitable for processing and manufacturing plastic products with large and extra-large sizes and complex structural shapes. Background technique [0002] The rotational molding machine is suitable for processing large-sized hollow products, so the rotational molding equipment itself is a large-scale mechanical equipment. The current rotomolding machines are almost all open structures, that is, the mechanical arm of the rotomolding machine is set outside the heating chamber. When the rotomolding machine is heating, the side door cannot be completely closed, leaving a large gap, because the mechanical arm needs to To bear heavy loads, it is necessary to design a larger size and space to meet the working needs; and the air duct and the heating chamber adopt a separate design, that is, the air duct is set outside...

AI Technical Summary

Problems solved by technology

The current rotomolding machines are almost all open structures, that is, the mechanical arm of the rotomolding machine is set outside the heating chamber. When the rotomolding machine is heating, the side door cannot be completely closed, leaving a large gap, because the mechanical arm needs to To bear heavy loads, it is necessary to design a larger size and space to meet the working needs; and the air duct and the heating chamber adopt a separate design, that is, the air duct is set outside the heating chamber. This structure causes a large part of heat loss. Causes long processing time cycle, low production efficiency and high energy consumption

In addition, after the existing rotomolding machine is manufactured, the structure and position of the mold frame and heating chamber are fixed and cannot be adjusted. When processing products of different sizes and shapes, especially products with complex shapes, the surface structure of the mold is complex. It is difficult to realize that each surface of the mold is heated in the center of the heating chamber, and it cannot effectively ensure that the mold is heated quickly and evenly, so the material is difficult to disperse evenly, and the quality precision of the processed product internal structure and surface texture is not high
