TECHNICAL FIELD
[0001] The utility model relates to a kind of spinning equipment technical field, specifically to a kind of wind tube structure for short fiber pre-spinning ring blowing device. BACKGROUND
[0002] Melt spinning is that high polymer spinning melt is extruded from the spinneret hole of the spinneret plate of spinning machine, and the extruded melt stream is sequentially cooled, oiled, and finally solidified into a yarn bundle. The existing short fiber pre-spinning spinning process is as follows: the melt is extruded from the screw extruder into the melt pipeline, then enters the spinning box, and is spun into a yarn bundle by the spinning assembly in the spinning box. The yarn bundle enters the ring blowing device for ring blowing cooling, then passes through the duct for secondary cooling, and finally is oiled on the oiling rack before being loaded into the yarn barrel as the original yarn for post-spinning drafting or other purposes.
[0003] Since the high polymer spinning melt is extruded from the spinneret hole of the spinneret plate of the spinning box, the extruded thin and dense melt strip from the spinneret plate is not yet solidified and shaped, but is in a high-temperature molten state, and the melt temperature is much higher than the ambient air temperature. Moreover, the melt strip at this time is extremely weak and tender, so it needs to be air-cooled by a cooling device.
[0004] The existing ring blowing device is a ring blowing cylinder, which is movably arranged below the spinneret plate by a lifting mechanism, and the duct is arranged on the floor, with the duct inlet protruding above the ground. During operation, the ring blowing cylinder is lifted to the lower side of the spinneret plate to cool the yarn bundle extruded from the spinneret hole. After cooling, the yarn bundle enters the duct for secondary cooling. When the spinneret plate needs to be cleaned, the ring blowing cylinder is lowered. The ring blowing cylinder is movably arranged below the spinneret plate, and the duct is arranged on the floor, so that there is a fault space between the ring blowing cylinder and the duct. During spinning, the yarn bundle passes through the fault space without any protection, and the melt yarn bundle is extremely weak and tender. When the yarn bundle passes through this space, it will sway, resulting in uneven thickness of the sliver, which affects the quality of the yarn bundle. SUMMARY
[0005] The utility model solves the technical problem to provide a kind of short fiber pre-spinning ring blowing device wind tube structure with simple structure, it is easy to operate, can avoid the sway of yarn bundle, make the sliver thickness more uniform, improve the quality of yarn bundle.
[0006] The utility model is realized as follows: a kind of short fiber pre-spinning ring blowing device wind tube structure, including a inner tube, bottom and top edge all have a outwardly protruding outer edge;

[0008] Two hooks are symmetrically fixed on the outer edges of the top of the inner cylinder respectively, and are hung below the ring blowing device through the hooks.
[0009] Further, the height of the inner cylinder, the height of the outer cylinder and the height of the duct entrance are the same.
[0010] Further, the inner diameter of the inner cylinder is greater than the inner diameter of the duct entrance.
[0011] The wind cylinder structure for the short fiber pre-spinning ring blowing device has the advantages that the inner cylinder and the outer cylinder which are hung below the ring blowing device are telescopic, the influence of the surrounding environment on the filament bundle can be avoided, the filament bundle is prevented from shaking, the thickness of the strip is more uniform, and the quality of the filament bundle is improved.
