Extrusion device and extrusion molding die used by same, monitoring device and program, strand manufacturing method, and strand diameter adjustment method

An extrusion molding die comprising:

• a main body portion in which a flow-in port, a plurality of through-holes and a flow path portion are formed, kneaded molten resin being supplied to the flow-in port, strands of the supplied molten resin being ejected from the plurality of through-holes, the flow path portion extending in a flow path direction from the flow-in port to the plurality of through-holes;
• and
• an adjustor that is able to adjust individually an ejection amount of the strand ejected from each of the plurality of through-holes,
• wherein the adjustor includes, for each through-hole, a corresponding temperature adjustment unit to individually adjust a temperature of the strand ejected from a corresponding through-hole.

An extrusion device comprising:

• a cylinder;
• a raw material feed port configured to supply raw materials including resin into the cylinder;
• a screw that is incorporated in the cylinder and kneads the raw materials, allowing the raw materials to be molten;
• a die that is disposed at one end of the cylinder and includes a plurality of through-holes to eject strands made of molten resin supplied from the cylinder;
• and
• an adjustor that adjusts individually an ejection amount of the strand ejected from each of the plurality of through-holes,
• wherein the adjustor includes, for each through-hole, a corresponding temperature adjustment unit to individually adjust a temperature of the strand ejected from a corresponding through-hole, and
• wherein the adjustor includes a tension adjustment unit to adjust tension acting on the strands ejected from the through-holes.
