Description

Technical Field

[0001] The utility model relates to the field of pneumatic gathering devices of compact spinning machines, in particular to a protective cover and a device for preventing special-shaped compact spinning tubes from clamping flowers. Background Art

[0002] The compact spinning machine adds a pneumatic gathering device for hairiness aggregation in the spinning triangle. The pneumatic gathering device consists of a special-shaped tube, a gathering ring and a tension support frame. The gathering ring is mounted on the gathering tube and the tension support frame, and the output roller located on the downstream side of the gathering ring presses on the driving roller to clamp the yarn. During the process of gathering and twisting the yarn, the cotton hairiness on the yarn and the flying flowers in the air will fly into the special-shaped tube to form a flower clamp phenomenon. After the flowers are accumulated, it is easy for the mesh ring to run out of the control range of the tension support frame and cause the mesh ring to deviate. For this reason, the special-shaped tube needs to be manually disassembled every seven to ten days to remove the flowers that fly into the special-shaped tube, which not only reduces production efficiency, but also increases the workload of operators.
