An installation cavity 53 is provided inwardly on one side of the bottom of the screw rod pair 52, a mounting seat 6 is installed in the installation cavity 53, a yarn breaking knife 61 is fixedly arranged at the bottom of the mounting seat 6, the yarn breaking knife 61 extends from the bottom of the screw rod pair 52, and a limiting hole 62 is vertically penetrated on one side of the top of the mounting seat 6. Through the arrangement of the mounting seat 6 and the installation cavity 53, the yarn breaking knife 61 can be quickly and stably installed on the screw rod pair 52.

[0023] It is also worth noting that the load-bearing plate 1 and the top plate 3 in the present technical solution are fixedly arranged on an external warping machine. The specific structure and working mode of the warping machine are existing technologies currently disclosed on the market. This is common knowledge known to those skilled in the art. They do not belong to the technical problems to be solved in the present technical solution. Therefore, the warping machine will not be described in detail in the present utility model.

[0024] Among them, an adjustment cavity 7 is provided inside the screw pair 52, located above the installation cavity 53 and close to the opening, and an adjustment block 8 is movably provided up and down in the adjustment cavity 7. A limit rod 81 is fixedly provided at the bottom of the adjustment block 8, and the limit rod 81 extends from the bottom of the adjustment cavity 7 to the installation cavity 53, and the limit rod 81 is adapted to the limit hole 62. A connecting cavity 71 is provided outwardly on one side of the adjustment block 8, and an adjustment rod 82 is fixedly provided on this side of the adjustment block 8, and the adjustment rod 82 passes through the connecting cavity 71 and extends out of the screw pair 52.

[0025] By setting the adjusting rod 82, the adjusting block 8 can be adjusted up and down, thereby realizing the up and down adjustment of the limiting rod 81. And by the adapter between the limiting rod 81 and the limiting hole 62, the mounting seat 6 can be fixed, thereby realizing the fixed installation of the yarn breaking knife 61.

[0026] Among them, a cylinder assembly 4 is installed on the top of the top plate 3, and the top extension end of the cylinder assembly 4 vertically passes through the top plate 3 and is connected to the top of the pressing plate 2. Through the arrangement of the cylinder assembly 4, the pressing plate 2 can be moved up and down. And it is worth noting that the specific structure and working mode of the cylinder assembly 4 are both existing technologies currently disclosed on the market, and they do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0027] There are multiple guide posts 11 vertically arranged between the load-bearing plate 1 and the top plate 3, and the pressing plate 2 is movable on the guide posts 11. The setting of the guide posts 11 can ensure that the pressing plate 2 remains stable during the up and down movement. A knife groove 12 is provided on the top of the load-bearing plate 1 corresponding to the yarn breaking knife 61.

[0028] Among them, a driving motor 5 is installed on one side of the pressing plate 2, and the output end of the driving motor 5 is connected to the screw rod 51. Through the setting of the driving motor 5, the screw rod 51 can be driven, so that the screw rod pair 52 on the screw rod 51 can be moved. And the specific structure and working mode of the driving motor 5, the screw rod 51 and the screw rod pair 52 are all existing technologies currently disclosed in the market, which do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

Thus, the yarn on the bearing plate 1 can be cut by the yarn cutting knife 61 at the bottom of the pressing plate 2.

[0030] Furthermore, the yarn cutter 61 is installed at the bottom of the screw rod pair 52. When the user needs to install the yarn cutter 61, he only needs to push the adjustment rod 82 upward. At this time, the adjustment block 8 and the limit rod 81 can be moved upward by the adjustment rod 82, and the mounting seat 6 above the yarn cutter 61 can be inserted into the mounting cavity 53 at the bottom of the screw rod pair 52. When the mounting seat 6 is completely inserted into the mounting cavity 53, the limit rod 81 is aligned with the limit hole 62, and the limit rod 81 can fall into the limit hole 62 by its own gravity, so that the mounting seat 6 and the yarn cutter 61 can be installed by the clamping between the limit rod 81 and the limit hole 62.

[0031] In the utility model, the device is installed on the warping machine. The yarn cutting can be achieved by setting the yarn cutting knife 61. The mounting seat 6 can be fixedly installed in the mounting cavity 53 on the screw pair 52 through the adapter between the limiting hole 62 and the limiting rod 81, thereby achieving fixed installation of the yarn cutting knife 61. This installation method is not only fast and convenient, but also very firm.
