Machine cylinder structure capable of adjusting temperature of machine cylinder uniformly

Abstract

The invention relates to a machine cylinder structure capable of adjusting the temperature of a machine cylinder uniformly. The machine cylinder structure capable of adjusting the temperature of the machine cylinder uniformly comprises a machine cylinder body; a flowing water through cavity capable of introducing water flow to change the temperature of a cylinder body is formed in the cylinder body of the machine cylinder; the flowing water through cavity consists of N strip-shaped holes which are formed in the cylinder body axially at intervals; the openings, positioned on the end part of themachine cylinder, of the N strip-shaped holes are connected end to end to form a whole tandem flowing water channel; a water inlet of the flowing water channel is positioned at the position of a starting part of the flowing water channel; a water outlet of the flowing water channel is positioned at the position of the tail part of the flowing water channel; and N is more than or equal to naturalnumber 4. The machine cylinder structure capable of adjusting the temperature of the machine cylinder uniformly has the following advantages: water flow entering the cylinder body flows through everywhere of the cylinder body through the strip-shaped holes which are connected end to end, so that everywhere of the cylinder body contacts the same water quantity, the temperature of the cylinder bodycan be adjusted uniformly and the problem in the prior art that the temperature of the cylinder body is non-uniform caused by the fact that the same flow quantity of multiple strands of water flow isdifficult to maintain when the multiple strands of water flow enters the cylinder body is solved.

Description

technical field [0001] The invention relates to the technical field of machine barrel production, in particular to a machine barrel structure capable of uniformly adjusting the temperature of the machine barrel. Background technique [0002] An existing Chinese utility model patent with the application number CN201721137878.5 titled "A Sheet Extruder Barrel Feed Cooling Mechanism" discloses a sheet extruder barrel feed cooling mechanism, including extrusion Extruder barrel, the barrel of the extruder is provided with a material inlet, characterized in that: the outer wall of the cooling section of the barrel of the extruder is provided with a plurality of half-ring grooves distributed along the axial interval, the extruder machine The outer wall of the cylinder cooling section is also provided with a straight groove axially penetrating each of the half-ring grooves; it also includes a cooling pipe, which has a plurality of half-ring cooling parts and straight cooling parts; ...

AI Technical Summary

Problems solved by technology

However, the barrel cannot uniformly change the temperature of the outer wall of the barrel, and the use effect is not ideal, so the structure of the barrel needs further improvement
