Problems solved by technology

[0004] In order to solve the problem that the existing segmented cast film extruder heating device can effectively heat the cast film, but in actual use, the internal heating layer needs to be overheated when the weather is cold. If it is too long, it will lead to an increase in power consumption, and the interface will become loose during use, resulting in poor heating

Abstract

The invention discloses a heating device of a sectional type cast film extruder. The heating device comprises a shell, a wiring port is formed in the outer side of the shell, an external reinforcing mechanism is installed in the wiring port, a heating layer is arranged in the shell, a preheating mechanism is installed in the shell, and a sectional butt joint mechanism is arranged in the shell. According to the heating device of the cast film extruder, when an existing heating device is used in winter, the needed preheating time is longer, so that the preheating cost is increased, a water pipeline is arranged in the shell of the heating device of the cast film extruder, and when preheating is needed, external heat flow can be guided into a water inlet to preheat the shell; the shell conducts heat to the internal heating layer, and a baffle is arranged in the water pipeline, so that the circulation time of heat flow is effectively prolonged, the preheating effect is guaranteed, the preheating cost is reduced, and the practicability of the heating device of the cast film extruder is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of extruders, and in particular relates to a heating device for a segmented casting film extruder. Background technique [0002] The plastic material enters the extruder from the hopper, and is conveyed forward by the rotation of the screw. During the forward movement of the material, it is heated by the barrel, sheared and compressed by the screw to make the material melt. , thus realizing the change among the three states of glass state, high elastic state and viscous fluid state. [0003] Although the existing segmented casting film extruder heating device can effectively heat the casting film, in actual use, the heating of the internal heating layer takes too long when the weather is cold. It leads to increased power consumption, and the interface is loose during use, resulting in poor heating. For this, we have designed a segmented casting film extruder heating device.
