Embodiment Construction

[0019] like figure 1 and figure 2 As shown, the present embodiment is a yarn tail cutting device 7, and the yarn tail cutting device 7 includes:

[0020] An upper pressing unit 71 located above the bobbin and used to compress the upper end of the bobbin;

[0021] The lower pressing unit 72 for pressing the base 1;

[0022] The negative pressure baffle 73 is provided with a negative pressure suction hole on the negative pressure baffle 73;

[0023] Yarn tail scissors 74 for cutting the yarn tail sucked from the negative pressure suction hole;

[0024] A drive mechanism for driving the yarn tail scissors 74 to work.

[0025] In this embodiment, when the yarn tail is cut, the top of the bobbin and the base 1 can be pressed by the upper pressing unit 71 and the lower pressing unit 72, and the negative pressure generated by the negative pressure suction hole at the negative pressure baffle 73 The yarn tail is sucked into the other side of the negative pressure baffle 73, and ...

Abstract

The invention discloses a yarn tail shearing device. A yarn tail shearing mechanism is used for shearing the tail end of the yarn, the yarn tail shearing mechanism comprises a upper pressing unit located above the tube and used for pressing the upper end of the tube; a lower pressing unit used for pressing the base; a negative pressure baffle plate, negative pressure suction holes are formed in the negative pressure baffle; yarn tail scissors are used for shearing the yarn tail sucked from the negative pressure suction holes; and a driving mechanism used for driving the yarn tail scissors to work. The yarn tail shearing mechanism further comprises a motor which is located below the base and is used for driving the cylinder tube to rotate. According to the yarn tail shearing device, the yarn tail part can be completely sheared, so that the tail end of the yarn can be conveniently found, and the tail end of the yarn can be conveniently inserted into the tube.

Description

technical field [0001] The invention belongs to the technical field of yarn processing, and in particular relates to a yarn tail cutting device. Background technique [0002] In the industrial production process, yarn production generally includes the following processes: (1) Spinning stage: generally ring spinning, producing bobbin yarn, bobbin yarn includes bobbin and yarn wound on the bobbin ; (2) Winding process: the yarn is unwound from the bobbin, its defects are removed and then wound into a package, which contains a greater number of yarns. The winding process is much faster compared to spinning, so that a small number of winding units or winding stations, on the order of a few dozen, enables the production of a large number of yarn units on the order of several thousand. Generally, the bobbin from the spinning machine is wound with its yarn end around the bobbin package or the bottom of its tube for a specified number of revolutions, the bobbin yarn end cut from th...
