Magnetic force suspension bobbin falling device

Abstract

The invention provides a magnetic force suspension bobbin falling device. The magnetic force suspension bobbin falling device comprises a bobbin, an assembling base, a connecting base and a rotating shaft. A yarn rolling vat is placed on the lower portion of the bobbin, and the lower bottom face of the connecting base is provided with lower sawteeth evenly distributed in the circumferential direction of the axis. The upper portion of the assembling base is provided with upper sawteeth evenly distributed in the circumferential direction of the axis. A magnetic block in the assembling base is attracted to the lower portion of the connecting base through magnetic force, and the upper sawteeth are meshed with the lower sawteeth. The rotating shaft and the assembling base are coaxially fixed. The bobbin is vertically fixed on the axial lower portion of the assembling base. According to the magnetic force suspension bobbin falling device, when the weight of yarn rolls is larger than the critical point, the yarn rolls automatically fall to the yarn rolling vat on the lower portion, and yarn rolling action is stopped. When the magnetic force suspension bobbin falling device is used, weight measuring and dismounting of the yarn rolls are achieved automatically, and labor is saved. The magnetic force suspension bobbin falling device is simple in structure, low in manufacturing and using cost, and the empty yarn rolls are assembled on the connecting base more conveniently.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a magnetic suspension doffing device. Background technique [0002] When spinning, the warp yarns that are spun generally all wind up the warp yarns through the bobbins at last to complete the collection of the warp yarns. The yarn bobbin is assembled on the rotating shaft when winding the warp yarn. When the yarn bobbin is finished winding, people unload the yarn bobbin full of warp yarn from the rotating shaft. The amount of wound warp yarn is similar, and the electronic length-fixing device is often used to measure the amount of warp yarn winding to finally determine the stop of the yarn bobbin. Although this method is more accurate, the structure is more complicated, and the winding amount of the yarn bobbin needs to be adjusted manually. Always detect, and when the warp yarn reaches a fixed length, it is necessary to manually replace the bobbin operation, and the ...

The yarn bobbin is assembled on the rotating shaft when winding the warp yarn. When the yarn bobbin is finished winding, people unload the yarn bobbin full of warp yarn from the rotating shaft. The amount of wound warp yarn is similar, and the electronic length-fixing device is often used to measure the amount of warp yarn winding to finally determine the stop of the yarn bobbin. Although this method is more accurate, the structure is more complicated, and the winding amount of the yarn bobbin needs to be adjusted manually. Constant detection, but when the warp yarn reaches a fixed length, it is necessary to manually replace the bobbin operation, which has a large workload; and once the operator is late, it may cause excessive winding of the warp yarn
