Protective cover for heat insulation and heat preservation of extrusion die head

Abstract

According to the technical scheme, a protective cover for heat insulation and heat preservation of an extrusion die head comprises the die head, a hot air box is connected to the two sides of the die head, hot air pipes are connected to the outer sides of the hot air box, a heat preservation cover is arranged in the outer side of the hot air box, the hot air pipes and the die head, the heat preservation cover comprises a top plate, a middle plate, left and right side plates and front and back side plates; the lower portions of the left and right side plates extend inwards to the bottom face of the hot air box, the left and right side plates cover the side faces and the bottom face of the hot air pipes and the hot air box, the middle plate covers the top faces of the hot air pipes and the hot air box, the top plate is located over the middle plate and covers the die head and the middle plate, and the front and back side plates cover the front side faces and the rear side faces of the hot air box, the hot air pipes and the die head. The protective with the independent heat preservation and insulation structure is arranged outside the die head, so that the heat preservation and insulation effect on the extrusion die head is achieved.

Description

technical field [0001] The invention relates to the technical field of melt-blown and spun-bonded die heads, in particular to a shield used for heat insulation and heat preservation of an extrusion die head. Background technique [0002] At present, many early meltblown and spunbond dies are either directly exposed to the air, with a large temperature difference in contact with the air, prone to defects such as broken wires and uneven discharge; or they are very simple insulation folding The insulation operation is carried out by inserting rock wool into the board. To achieve a stable effect for the product, this method cannot meet expectations. Therefore, in order to make products with higher requirements and meet market demand, this technology must be improved. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a shield for heat insulation of the extrusion die, which can effectively achieve the effect of heat insulati...
