Description

Technical Field

[0001] The present invention relates to the technical field of spinning production, and particularly to a movable upward oiling mechanism and a spinning, drawing and winding combined machine. Background Art

[0002] Most of the existing fiber spinning, drawing and winding equipment for the polylactic acid industry is modified from other types of equipment, and the biggest disadvantage is the instability of product quality and performance.

[0003] When drawing and winding the filament of the biobased polylactic acid industry, a higher speed is required compared with that of general petroleum-based synthetic fibers. If an oil wheel is used for oiling, the filament bundle will rub against the oil wheel due to the high speed, and friction often occurs between fibers and between fibers and the equipment. This will not only damage the fiber surface, but also easily cause hairiness and breakage of the fibers during processing and generate additional tension. Due to the friction, the electrostatic effect is very obvious. Due to the electrostatic phenomenon, the repulsive force between single fibers will cause the filament bundle to not be well held together, thus affecting the processing process. Summary of the Invention

[0035] By providing a movable upward oiling mechanism and a spinning-drawing-winding combined machine in an embodiment of the present application, the technical problems in the related art that during the spinning of polylactic acid fibers, due to the relatively high speed, there are problems such as friction with the oil wheel, damage, broken ends, and the electrostatic effect affecting the cohesion are solved.

[0036] The technical solutions in the embodiments of the present application for solving the above technical problems are generally as follows:

[0037] A movable upward oiling mechanism includes multiple pairs of nozzles. Each pair of nozzles includes two nozzles respectively located on the radial two sides of the to-be-oiled tow. Each pair of nozzles is configured to approach each other in the top view direction to form a spinning state, and to move away from each other in the top view direction to form a head feeding state.

Each pair of oil nozzles 11-3 includes two oil nozzles 11-3 respectively located on the radial two sides of the to-be-oiled tow 11-4. Each pair of oil nozzles 11-3 is configured to approach each other in the top view direction to form a spinning state, and to move away from each other in the top view direction to form a threading state.

[0041] Specifically, the to-be-oiled tow 11-4 is oiled by multiple pairs of oil nozzles 11-3. Each pair of oil nozzles 11-3 oils one tow 11-4. Each pair of oil nozzles 11-3 includes two oil nozzles 11-3, and the two oil nozzles 11-3 are respectively located on both sides of the tow 11-4. The oil nozzles 11-3 are set to be movable, so that different positions of the oil nozzles 11-3 can form a spinning state for oiling the tow 11-4 and a threading state for threading and hanging the tow 11-4, which is convenient for actual operation.

[0042] By the oil nozzles 11-3 respectively on both sides of the to-be-oiled tow 11-4, the purpose of oiling both sides of the tow 11-4 is achieved. It can increase the bundling property, antistatic property of the polylactic acid fiber, reduce the resistance of fiber stretching. The function of uniformly spraying oil on the tow 11-4 can increase the cohesion between monofilaments in the tow 11-4, improve stretching and thus reduce broken filaments, and improve the full bobbin rate of the finished product.

[0046] In other implementable embodiments, the cylinder 11-1 can be replaced with power components such as a motor or an oil cylinder. Using the cylinder 11-1 has the advantage of a clean medium.

[0047] Among them, the cylinder 11-1 is configured with an electrical control system to electrically control the cylinder push rod 11-2 to extend, retract, or maintain an immobile state.
