Description

Technical Field

[0001] The present invention relates to the technical field of yarn packaging, and particularly relates to a winding and packaging device for preparing electrospun yarns. Background Art

[0002] In the industrial production of electrospun yarns, after the electrospun yarns are produced and wound up, and the yarn rollers are individually packaged with PE heat shrinkable film. In order to facilitate the storage and transportation of the yarn rollers, most operators need to arrange multiple yarn rollers on a tray and then use a bundling machine to bundle the yarn rollers.

[0003] For example, the existing application number CN202011422812.7 discloses a banding machine, which includes a main body, an inlet wheel group, a winding mechanism and a joining mechanism. The inlet wheel group includes one or more rollers rotatably arranged on the main body. The winding mechanism includes a winding drive motor, a winding seat, a winding head, a pressing rod, a decompression motor and a decompression rod. The winding seat is connected to the output shaft of the winding drive motor. The winding head is arranged on the winding seat. The decompression rod is connected to the output shaft of the decompression motor. The middle of the pressing rod is rotatably matched with the winding seat. The joining mechanism is movably arranged on the main body and is opposite to the winding head. When pressing, the first end of the pressing rod abuts against the winding head, and the decompression rod is separated from the second end of the pressing rod. When feeding, the decompression rod abuts against the second end of the pressing rod, and the first end of the pressing rod is separated from the winding head. The banding machine provided by the present invention can be used for banding the blood collection blood bag's blood matching catheter and multi-chamber bag, improving the bundling efficiency and reducing the labor intensity.

[0004] However, during the process of bundling the yarn rollers, most operators need to push the yarn rollers to be bundled to a specific position of the bundling machine, bundle and package them, then transport the bundled and packaged yarn rollers, and then push the next yarn roller to the specific position. This not only increases the workload of the operators, affects the packaging efficiency of the yarns, but also easily causes deviation in the bundling position due to the negligence of the staff, and the yarn rollers slide or fall due to the sudden stop and start when manually pushing and pulling the yarn rollers. This not only exacerbates the yarn wear phenomenon caused by collisions, but also easily causes the slipping and uneven tension of the tie straps, affecting the bundling and packaging effect of the yarn rollers. Summary of the Invention

[0005] In view of this, the present invention provides a winding and packing device for preparing electrospun yarns, which uses a pushing auxiliary mechanism to automatically push the yarn roller to the bundling area of the operation support table, reducing the working burden of the operator, improving the positioning accuracy of the yarn roller and the positioning bracket when bundling the yarn roller, avoiding the slipping phenomenon of the cable tie, ensuring the uniform force of the bundling belt during bundling and the bundling effect on the yarn roller. At the same time, the yarn roller is pushed at a constant speed, greatly avoiding the sliding or tipping of the yarn roller caused by the sudden stop and start when manually pushing and pulling the yarn roller, and the yarn wear phenomenon caused by the tipping of the yarn roller, further improving the bundling and packing effect of the yarn roller. At the same time, during the automatic pushing process of the yarn roller, the cooperation of the first rack and the second rack is used to realize the operation mode of double-station pushing. In the double-station mode, the bundling frame can keep running continuously, avoiding the equipment idleness caused by manually stacking the pallets, improving the bundling and packing efficiency of the yarn wheel, and the working efficiency of the device in the actual application process. In addition, after the yarn roller is stacked on the positioning bracket, the positioning pillar automatically centers the central hole position of the yarn roller. When the yarn roller is sleeved on the positioning pillar, after the conical surface contacts the inner wall of the roller hole, the yarn roller body will vertically fall along the axis of the positioning pillar due to the inclined surface component force, reducing the positioning error, automatically correcting the yarn roller, without manual fine-tuning, simplifying the operation steps when stacking the yarn roller on the positioning pillar, and at the same time realizing the positioning assistance between the upper and lower adjacent positioning brackets, improving the stacking efficiency of the yarn and the stability when stacking the yarn rollers.

[0017] Beneficial effects
