Plastic cushion with pipe network and floss silk and production technique thereof and rotary forming head

Abstract

Pipe network and floss coexisting type plastic cushion comprises plastic flosses which are randomly arranged and have connecting points, in which there is a pipe network. The technical steps are: sending raw materials into an extruder to heat and plasticize to form a fusant shape; extruding out via a rotating type forming machine head; plastic threads extruded from a discharge hole of a fixing model downwards running to the random flosses via a forming roller, and forming a connecting point at the mutual connecting point; plastic threads extruded from the peripheral groove of a rotating model in the inner side of the fixing model forming the pipe network shape, having a cavity in the pipe network shape; cooling and typing the extruded formed plastic cushion, whose middle has the pipe network distribution and the periphery has the flosses; drawing out the formed plastic cushion to a cooling machine, and according to the specification to cut. The rotating type forming machine head structure is to mount a rotating model and a processing groove on the fixing model. The rotating model is connected with a rotating mechanism. This technology and the cushion for machine head have proper integral density, proper thread-line connecting point, high firmness degree, and do not need the spraying glue enhancement, without pollution. And this invention can be equipped with the temperature adjusting component.

Description

technical field [0001] The invention relates to a coexisting plastic soft pad with a pipe network and random threads, a production process thereof and a rotary molding machine head used in the production process. Background technique [0002] The traditional plastic elastic soft mattress is composed of disordered plastic filaments. The production process is to send the raw materials into the extruder for heating and plasticizing to form a melt, and then extrude downward through a fixed porous spinneret. The materials are piled up to form a disordered adhesion-like silk mat, and then the products are made through complicated processes such as setting, cooling, cutting, spraying glue to increase firmness, attaching to the base mat, and drying. Due to its technological characteristics, the disordered plastic filaments are excessively overlapped when they are adhered, and the space cannot be fully and effectively used, resulting in a heavier mass per unit volume; and because the...

AI Technical Summary

Problems solved by technology

Due to the characteristics of the process, there is too much overlap when the disordered plastic filaments are bonded, and the space is not fully and effectively used, resulting in a heavy weight per unit volume; and because the plastic filaments are bonded after leaving the template, it affects the bonding. Fastness

Although the performance has been improved by spraying glue, the overall fastness is still not ideal, and it is difficult to ensure the uniformity of glue spraying; at the same time, it must be dried quickly after spraying glue, which produces a lot of harmful volatile substances. pollution of the environment

The overall strength of the product is poor, there is no space inside the pad for heating or cooling components, and the use is limited
