Abstract

The invention provides a roller which comprises a cylindrical body, two protruded portions, combining portions and bolts. An accommodating passage is arranged on the cylindrical body axially. The two protruded portions are protruded from two sides of the body axially, and a first flat plane of each protruded portion is provided with two blind holes. The combining portions are respectively provided with two through holes, and the protruded portions are combined with the combining portions to form a disc. The bolts extend into the through holes and are screwed with the blind holes. Since the roller is of a movably split structure, convenience in mounting and demounting the roller is improved, fixing force between the roller and a roller shaft is increased, and safety of a plastic rolling machine is improved.

Description

technical field [0001] The invention relates to a roller, in particular to a roller used in a rotational molding machine for bearing the rotation of a rotational molding mold. Background technique [0002] As an important branch of plastic molding processing technology, rotational molding technology is receiving more and more attention because of its advanced technology and strong market competitiveness of products. It is suitable for manufacturing large-scale hollow rotational molding products. At present, the rotomolding process is usually realized in a rotomolding machine. [0003] The rotomolding machine generally includes: a support, a swing table arranged on the support, a flame injection device and a rotational molding mold arranged on the swing table. The rotomolding mold is arranged on two roller shafts arranged in parallel on the swing table, and the roller shafts are provided with several rollers, so as to support and drive the rotomolding mold to pivot throu...
