Embodiment Construction

[0022] With reference to these figures, the temperature probe, in particular for thermoplastic compound extruders, generally indicated with reference numeral 1 , comprises at least one housing 2 and at least one thermocouple 3 accommodated inside the housing 2 .

[0023] As will be better described hereinafter, the housing 2 is adapted to be inserted into the extrusion cylinder 4 substantially at right angles to the direction of extrusion, with one end facing into the inner cavity 5 of the extrusion cylinder 4, so that the housing and the The extruded material in cavity 5 is in direct contact.

[0024] Consider a thermocouple 3 adapted to detect the temperature of the extruded material circulating in the cavity 5 by heat conduction through the housing 2 .

[0025] According to the invention, thermal insulation 6 is included at least partially between housing 2 and extrusion cylinder 4 in order to reduce the thermal influence of the latter on the measurements made by thermocoup...

Abstract

The application relates to a temperature probe (1) and an extruder (100). The temperature probe, in particular a temperature probe (1) for a thermoplastic compound extruder, comprises at least one housing (2) adapted to be inserted into the extrusion cylinder (4) substantially at right angles to the extrusion direction ), one end of which faces into the lumen (5) of the extrusion cylinder (4), such that the housing is in direct contact with the extruded material contained in the lumen (5); and at least one thermocouple (3), which accommodates In the housing (2), and adapted to detect the temperature of the extruded material by heat conduction through the housing (2), the temperature probe (1) includes at least partly between the housing (2) and the extrusion cylinder ( 4) to reduce the thermal influence of the extrusion cylinder (4) on the measurements made by the thermocouple (3).

Description

technical field [0001] The present invention relates to a temperature probe, in particular a temperature probe for a thermoplastic compound extruder. Background technique [0002] Currently, international specifications covering self-extinguishing wires or flame-retardant wires (HFFR, Halogen Free Flame Retardant) and wires that have low dust and mist emissions and are halogen-free when burned (LSOH, Low Smoke Halogen Free) have directed manufacturers of compounds to produce such thermoplastic mixtures, which make it difficult for one to work in this environment due to the large amount of heat generated during the handling of such thermoplastic mixtures, which are generated due to their high viscosity. Excessive heat has the disadvantage of causing material degradation. [0003] Such thermoplastic mixtures are usually processed in extruders, which face the above-mentioned technical difficulties and, due to the special composition of the mixture itself, its extrusion speed i...
