Example Embodiment

[0045]The following is attachedFigure 1-3Give further details on this application.

[0046]The first embodiment of the present application discloses a direct immersion cooling and shaping processing production line of polyoxymethylene rods. Referencefigure 1 , A direct immersion cooling and shaping processing production line for POM rods, which in turn includes a material blanking machine 1, a material extruder 2, a cooling station 4, a traction station 7 and a cutting station 9. After the raw materials are first put into the material feeder 1, the stirred raw materials are extruded through the extruder head 3 of the material extruder 2 to form a plastic rod. At the first time of extrusion, the plastic rod is solidified and cooled by the cooling sizing sleeve 5 in the cooling station 4, and the cooling water tank 6 is cooled as a whole, and finally cut into the required length by the cutting station 9 and then pulled The station 7 is arranged between the cutting station 9 and the cooli...

Abstract

The invention relates to a direct immersion type cooling shaping processing production line of a polyformaldehyde bar and a processing method of the direct immersion type cooling shaping processing production line. The direct immersion type cooling shaping processing production line comprises a material feeding machine, a material extruder, a cooling station, a traction station and a cutting station; the cooling station comprises a cooling shaping sleeve and a cooling water tank which is positioned on the rear side of the cooling shaping sleeve and is used for direct immersion of the bar; andthe cooling shaping sleeve comprises a shaping mold and a immersing cooling chamber, the shaping mold is provided with a discharging hole coaxial with an extruder head, the immersing cooling chamber is arranged on one side of the shaping mold, one end of the immersing cooling chamber communicates with the discharging hole, a discharging sealing hole allowing a bar to be pushed out is formed in theother end of the immersing cooling chamber, and the shaping mold and the immersing cooling chamber are both connected with a cooling water pipe group. Water is supplied to the discharging hole in theshaping mold, an extruded rod body is indirectly cooled and shaped, and then is directly cooled in a direct immersion manner, so that the rod body is always cooled by relatively low-temperature cooling water in a curing stage, and the problem that a gap is generated in a core part due to temperature difference is solved.

Description

technical field [0001] The present application relates to the field of plastic processing technology, in particular to a direct immersion cooling and shaping production line for polyoxymethylene rods and a processing method thereof. Background technique [0002] At present, extrusion molding is also called extrusion molding or extrusion molding. It mainly refers to the extrusion of a screw or a plunger, so that the heated and melted polymer material is forced to pass through the mold of the die under the pressure to form a A method of forming continuous profiles of constant cross-section. The extrusion molding process mainly includes the processes of feeding, melting plasticization, extrusion molding, shaping and cooling. It generally includes a plastic extruding main machine, and an auxiliary machine composed of a machine head, a shaping device, a cooling device, a traction device, a coiling device, a cutting device and other devices. [0003] At present, some highly crys...
