Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic extruder, concretely to a barrel cooling device of plastic extruder. BACKGROUND

[0002] The plastic extruder is usually called main machine, and the subsequent equipment plastic extrusion molding machine is called auxiliary machine. The plastic extruder can be matched with various plastic molding auxiliary machines such as pipe, film, profile, granulation and cable covering to form various plastic extrusion molding production lines and produce various plastic products.

[0003] The prior art patent document CN205395097U discloses a screw barrel cooling device. The medium flows in the extension protrusion in the first cooling flow channel or the second cooling flow channel, so that the medium takes away more heat in the flow process, and the purpose of rapid cooling is achieved. The second heat exchange blade is spirally arranged on the inner wall of the second cooling flow channel along the axis direction of the second cooling flow channel. The second heat exchange blade arranged on the inner wall of the second cooling flow channel enables the medium to flow in a spiral manner in the flow process, increases the flow path of the medium, and enables the medium to more fully contact the inner wall of the second cooling flow channel and the second heat exchange blade, so that the medium takes away more heat in the flow process, and the purpose of rapid cooling is achieved. The connecting flange at one end of the screw barrel is located on the outer wall of the screw barrel to form a positioning protrusion part protruding from the face where the connecting flange is located. The connecting flange at the other end is located on the outer wall of the screw barrel and protrudes from the screw barrel to form a positioning recess part matched with the positioning protrusion part. The positioning protrusion part is embedded into the positioning recess part of another same screw barrel for limiting and fixing, so that the assembly process is faster and less prone to errors. The sealing performance of the connection between the two screw barrels is further improved, the annular sealing ring is not directly exposed to the outside, the annular sealing ring is less prone to aging, and the service life is prolonged. The cooling circulating flow channel arranged on the screw barrel can introduce cooling medium into the cooling circulating flow channel when the temperature of the screw barrel is too high, so that the cooling medium can flow back and forth in the axis direction of the screw barrel to uniformly cool the screw barrel.

[0004] However, the cooling and heat conduction capacity of the screw barrel cooling device in the prior art patent CN205395097U is not good, which leads to the fact that the plastic extruder cannot be quickly and conveniently heat-conducted according to the needs in the actual use process of the screw barrel cooling device, the cooling and heat dissipation of the barrel cooling device are inconvenient, and the cooling effect of the screw barrel cooling device is affected.
