And the exhaust fan 14 is fixedly installed on the inner side of the outer upper end of the fixed table 1. Specific embodiment one

[0030] In order to solve the problems in the prior art that it is not convenient to convey and press and limit the cotton yarn strip, it is difficult to sharpen the blade 9, and the cutting efficiency and effect are limited. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 , Figure 2 , Figure 3 and Figure 4, first, the device can be placed at the position to be used. Then, screws can be installed through the installation holes 2 symmetrically opened inside the lower end of the outer side of the fixing table 1 to fix the device. Next, the cotton yarn strip to be cut can be placed on the conveyor belt 3 installed inside the inner side of the lower rear end of the fixing table 1. Then, the conveyor belt 3 inside the inner side of the lower rear end of the fixing table 1 can be controlled to operate through the controller 4 embedded and installed inside the upper right rear end of the fixing table 1 to convey the cotton yarn strip on the conveyor belt 3;

[0031] When the position to be cut of the cotton yarn strip is conveyed to the upper side of the middle part of the lower end of the fixing table 1 and the blade 9 is located above the position to be cut of the cotton yarn strip, the first electric telescopic rod 6 fixedly installed inside the lower end of the outer side of the fixing table 1 can be controlled to operate through the controller 4, so that the first electric telescopic rod 6 drives the hollow plate 5 fixed thereon to move downward under the clamping and limiting of the fixing table 1 until the hollow plate 5 is pressed down and fits on the cotton yarn strip to achieve the purpose of pressing and limiting the cotton yarn strip to avoid affecting the cutting due to later offset. Then, the second electric telescopic rod 7 embedded and installed inside the upper end of the fixing table 1 can be controlled to operate through the controller 4, so that the second electric telescopic rod 7 drives the tool holder 8 fixed below it to descend under the fitting and limiting of the fixing table 1, so that the tool holder 8 drives the blade 9 bolt-fixed inside it to descend, and the blade 9 cuts the cotton yarn strip below it;

[0032] Such as Figure 1 、 Figure 2 and Figure 5 , a receiving strip 10 symmetrically fixed to the fixing table 1 is arranged on the outer side of the outer end of the blade 9.

Specific Embodiment Two

[0034] In order to solve the problem that it is not convenient to suck, filter, collect and clean the dust generated during cutting in the prior art, therefore, this embodiment adopts the following technical solutions, such as Figure 1 、 Figure 2 and Figure 3, during the process of cutting and pressing the cotton sliver, the controller 4 can be used to control the solenoid valve 15 fixedly installed on the inner side of the outer upper end of the fixed table 1 to operate, so that the fixed table 1 and the transfer bin 16 fixed on the fixed table 1 are connected in communication. Then, the controller 4 is used to control the exhaust fan 14 installed under the solenoid valve 15 to operate. Since the exhaust fan 14 is fixedly installed on the inner side of the outer upper end of the fixed table 1, a yarn bag 17 and an elastic sleeve 18 are sequentially nested on the outer side of the upper end of the transfer bin 16, and the elastic sleeve 18 is nested and fitted outside the yarn bag 17. Therefore, through the operation of the exhaust fan 14, it is convenient to suck the dust generated by cutting into the transfer bin 16 through the upper end of the fixed table 1, and then filter and collect it through the yarn bag 17 limited by the elastic sleeve 18. After cutting, the controller 4 can be used to control the solenoid valve 15 to operate to disconnect the communication between the fixed table 1 and the transfer bin 16, so as to prevent the dust in the transfer bin 16 and the yarn bag 17 from falling. And after long-term use, the elastic sleeve 18 can be removed from the transfer bin 16 to disconnect the connection between the yarn bag 17 and the transfer bin 16, and the dust collected in the yarn bag 17 can be cleaned.
