Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a suspended-spindle roving frame capable of realizing collective doffing. Background Art

[0002] Roving frames are key equipment in the textile process. 2 to 3 roving frames can supply 10,000 spindles of roving frames. The number of spindles in a suspended spindle roving frame is generally 96 to 216, and the yarn is dropped every 2 to 3 hours. At present, the doffing work of roving frames is generally done manually, which has high labor intensity, long time consumption and low production efficiency. In order to reduce the labor intensity of the workers and improve production efficiency, it is urgently necessary to replace the roving frames with manual doffing with automatic collective doffing. However, the price of purchasing new automatic collective doffing roving frames is very expensive, and it is a waste to eliminate the manual doffing roving frames with other intact functions. Therefore, transforming the original roving frames that can only doff manually into automatic collective doffing roving frames has become the best solution to reduce production costs, reduce labor intensity and improve production efficiency.

[0003] The key to achieving collective doffing on the roving frame is the doffing exchange mechanism that lifts up the full bobbin and releases the empty bobbin, the spindles installed on the doffing exchange mechanism, and the spindle pushers and two spindle support plates on the spindles. The distance between the spindles is half of the spindle pitch of the roving frame. The empty spindles and the spindles with empty bobbins are arranged at intervals. When doffing, the empty spindles are aligned with the inner holes of the full bobbin on the bobbin gear. The spindles descend with the doffing exchange mechanism. The inner holes of the full bobbin contact with the spindle pushers on the empty spindles and push the spindle pushers to move upward, thereby triggering the two spindle support plates to open and lift the full bobbin. The doffing exchange mechanism rises until the lower parts of the full bobbin and the empty bobbin are higher than a certain size above the upper part of the bobbin gear. The doffing exchange mechanism rotates to make the empty bobbin and the full bobbin translate half a spindle position. At this time, the empty bobbin The tube is aligned with the bobbin gear, and the yarn-dropping exchange mechanism descends for the second time to align the empty bobbins one by one and place them on the bobbin gear. At the same time, the inner hole of the empty bobbin triggers the hanging spindle push block, the two branches of the hanging spindle close, the hanging spindle is disengaged from the empty bobbin, and the empty bobbin placement work is completed. Finally, the yarn-dropping exchange mechanism rises to realize collective yarn drop; at present, most of the roving machines are suspended spindle, large package, and upper spindle rod roving machines. The top of the lower rib cover plate of the existing roving machines is a large plane, and the top of the plane is only 3 to 8 mm lower than the supporting plane of the bobbin gear. The triggering action stroke of the hanging spindle push block is 20 to 45 mm. When the yarn-dropping exchange mechanism descends, the lower part of the empty bobbin base interferes with the lower rib cover plate, and the yarn-dropping exchange mechanism cannot complete the work of exchanging the full yarn tube on the bobbin gear for the empty bobbin.

[0004] Chinese Patent No. CN02244320.7 discloses a closed spindle wing for a suspended spindle roving machine. By making the yarn guide channel of the suspended spindle wing closed, there is no air flow vortex at the outlet of the roving, and the fiber bonding force is strengthened without divergence; since the yarn guide channel is made of stainless steel pipe, its inner wall is smooth and unobstructed without fiber hanging, and the roving is not broken; furthermore, since the yarn guide channel of the suspended spindle wing is closed, the wind resistance becomes smaller and the power consumption is reduced, thereby greatly improving the spinning quality, but the function of automatic collective yarn dropping of the old roving machine is not realized.

[0005] To sum up, developing a suspended spindle roving frame that can realize collective yarn doffing, transforming the roving frame with manual yarn doffing into an automatic collective yarn doffing frame, reducing costs, reducing workers' labor intensity, and improving production efficiency have become issues that relevant technical personnel in this field urgently need to solve.
