Single air-inflation structure for working arm of rotational moulding machine

Abstract

The invention discloses a single air-inflation structure for a working arm of a rotational moulding machine, relating to a structure of the working arm of a rotational moulding machine used for producing a hollow rotational moulded product by using a plastic power material. The single air-inflation structure is composed of a main shaft, an auxiliary shaft, an arm head, a disc gear, a mandrel and the like, and the structure is technically characterized in that the single air-inflation structure is added in the working arm of the rotational moulding machine; the single air-inflation structure mainly comprises an air-inflation joint, an air-inflation tube and the like, an air-inflation port is arranged on the air-inflation joint and used for connecting the input end of the air-inflation tube, correspondingly, an air inlet channel is arranged in the arm head and used for connecting the output end of the air-inflation tube, and an air outlet hole and an air outlet channel are formed in the mandrel; and a single air-inflation path is that air enters in a rotational moulding die through the air-inflation port, the air-inflation tube, the air inlet channel, the air outlet hole and the air outlet channel sequentially. The rotational moulding machine has the advantages of shortening machining time, saving energy, improving the quality of the rotational moulded product, increasing production efficiency and the like by adding the structure capable of being automatically inflated with air in the working arm.

Description

technical field [0001] The invention relates to a single-inflatable structure in mechanical equipment, in particular to a single-inflatable structure used for the working arm of a rotational molding machine in rotational molding equipment for hollow plastic products. Background technique [0002] The rotomolding machine is a kind of rotomolding equipment that uses plastic powder to make hollow rotomolded products. It mainly drives the uniformly heated rotomolding mold to rotate around the X-axis and Y-axis through a working arm, so that the molten plastic in the rotomolding mold The powder is evenly coated and adhered to the entire inner surface of the rotomoulding mold under the action of gravity, so that the rotomolding product is formed, and after cooling and setting, the finished product can be taken out after opening the mold. At present, the arm type of the working arm used in the rotomolding machine is mainly a straight arm, which is mainly composed of a main shaft, a...

Problems solved by technology

However, the inflation of this patented structure only acts on the cooling process of the rotomolding mold. Because the design of the inflatable structure is too simple, when the rotomolding mold enters the oven to heat, the inflatable structure obviously cannot work normally, so there are large structural defects.
