Polymer fiber spinning component disassembly system and disassembly method

Abstract

The invention belongs to the technical field of melt spinning. A dismantling system for polymer fiber spinning components, which is used to realize the dismantling of spinning components, specifically including a heat preservation trolley, a press, a force wrench, an ejector, a holder, an inner core decomposition device and a separation knife, The heat preservation trolley is used for storage and heat preservation of the spinning assembly; the press is used to apply pressure to the deflector of the spinning assembly, and the pressure head of the press fits the deflector accordingly; the force wrench includes the working end and the force application arm, the working end is matched with the lock nut; the ejector device is used to separate the inner core of the assembly in the spinning assembly from the ejection housing; the clamper is used for clamping and transferring of the spinning assembly; the inner core disassembly device is used for The aluminum ring on the sand box is extruded and deformed; the separating knife is used for component separation and cleaning of residual materials. Also disclosed is a method for dismantling polymer fiber spinning components. The structural design is reasonable, which can greatly improve the disassembly efficiency, and burn the disassembled parts, which improves the cleaning efficiency, reduces the difficulty of operation, and makes each process proceed in an orderly manner.

Description

technical field [0001] The invention belongs to the technical field of melt spinning, and in particular relates to a dismantling system and a dismantling method of a polymer fiber spinning component. Background technique [0002] Melt spinning is a molding method that takes polymer melt as raw material and uses a melt spinning machine to spin. [0003] During melt spinning, the bulk polymer is sent to the spinning position after melting, quantitatively sent to the spinning assembly through the spinning pump, filtered, and extruded from the capillary holes of the spinneret. The liquid filaments are gradually solidified when they pass through the cooling medium, and then stretched into filaments at high speed by the winding device below. The filaments are primary fibers, and the primary fibers are post-processed into fibers. In order not to make the filaments cool too fast and make it difficult to form filaments, isothermal melt spinning is sometimes used, that is, an isother...

Problems solved by technology

In order to ensure the spinning quality of the components on the machine, the components on the lower machine have to go through multiple processes such as calcination, decomposition, salt bath, ultrasonic cleaning, automatic detection, etc. Usually, the components on the lower machine are directly loaded into the furnace for overall calcination. Using this calcination method, it is found that there are still a large number of carbide residues, impurities or burrs, blocked holes, half-blocked holes, etc. in the micropores of the spinneret sand box, which need to be burned again. The increase of the amount of impurities in the micropores gradually increases, and the pore size gradually decreases. After installation, the yarn drifts, the holes are blocked, and the glue leaks on the board surface, which affects the spinnability.
