Detailed Description

To facilitate an understanding of the present invention by those skilled in the art, specific embodiments thereof are described below with reference to the accompanying drawings.

As shown in figures 1-5, the invention changes the distance from the cutting point of the yarn cutting mechanism to the yarn inlet of the yarn preparation element, namely the length of the yarn preparation end, by changing the position of the cutting point of the yarn cutting mechanism.

A yarn shearing device is characterized in that a yarn clamping mechanism is arranged on the outer side of an installation plate 1, and a shearing mechanism is arranged on the inner side; the shearing mechanism comprises fixed scissors 8 and movable scissors 7, and the distance h from the shearing points of the fixed scissors 8 and the movable scissors 7 to the mounting plate 1 is 2 mm-12 mm. The outer layer of the scissors mounting post 101 is sleeved with a supporting shaft sleeve 102; the movable scissors 7, the fixed scissors 8 and the spring pressing sheet 104 are arranged at the upper ends of the scissors mounting column 101 and the supporting shaft sleeve 102 and are fixed through screws; the lower end of the scissors mounting column 101 penetrates through the sealing gasket 103 to be arranged on the mounting plate 1, and the shaft shoulder of the supporting shaft sleeve 102 presses the sealing gasket 103; one end of the movable scissors is riveted with a rolling shaft 5, the rolling shaft 5 penetrates through a sealing gasket 103 and the arc-shaped track 11, and the sealing gasket is tightly attached to the arc-shaped track. . The yarn guide plate 91 is mounted on the mounting plate 1 via the yarn guide plate mounting shaft 92, and the side surface of the fixed scissors 8 is fitted into the yarn guide plate mounting shaft 92 to restrict the rotation of the fixed scissors 8.

The yarn clamping mechanism comprises a yarn clamping rod 3, a connecting rod 6, a roller 2 and a yarn clamping block 4; the connecting rod 6 and the yarn clamping rod 3 are arranged on the mounting plate 1 through a movable shaft and are connected through a spring 31, and one end part of the connecting rod 6 is provided with a roller 2; the yarn clamping block 4 is fixed on the mounting plate 1 and is arranged opposite to one end of the yarn clamping rod 3. The other end of the connecting rod 6 is a U-shaped structure 61, and the U-shaped structure 61 is clamped on the roller 5.

The yarn shearing devices are arranged on two sides of the yarn processing device in actual use, the cam in the yarn processing device is used for stirring the roller 2 to move, the yarn clamping rod 3 is used for clamping the yarn, and the shearing device is used for shearing the yarn. The yarn cutting device on the left side of the yarn processing device clamps the first yarn, and the yarn cutting device on the right side cuts the first yarn; the yarn shearing device on the right side of the yarn processing device clamps the second yarn, and the yarn shearing device on the left side of the yarn processing device shears the first yarn.
