Description

Technical Field

[0001] The utility model relates to the technical field of roving frames, in particular to a thread supply device for roving frames. Background Art

[0002] A roving frame is a spinning machine that turns fiber strips into roving. Roving frames are divided into wing-spindle roving frames and twist-roving frames according to the twisting mechanism. Wing-spindle roving frames rely on the rotation of the spindle wings to continuously apply twist to the yarn strips to produce twisted roving. Twist-roving frames rely on a pair of twisting leather plates to clamp and twist the yarn strips, forming a false twist with alternating positive and reverse twists on the yarn strips to produce non-twist roving. Wing-spindle roving frames and twist-roving frames can be divided into first-pass, second-pass and one-way roving frames. The feeding forms, roving packages and number of spindles of various roving frames are different, but the machine structure and function are roughly the same.

[0003] In the prior art, the existing roving frame feeding device on the market usually adopts a dust cover to protect the guide roller and the textile slivers on the guide roller from dust during use. However, during long-term use, the dust cover has poor sealing performance on the guide roller, and other impurities such as dust and cotton wool accumulate on the dust cover and the guide roller inside the dust cover, which makes the equipment's dust prevention and impurity removal effect on the guide roller and the textile slivers on the guide roller worse, affecting the equipment's performance. To this end, we propose a roving frame feeding device for solving the above problems. Utility Model Content
