[0049] Among them, in order to achieve the purpose of controlling the operation of the fan 11, the present device adopts the following technical solutions: the control component includes a control switch 36, the control switch 36 is fixedly connected to the front side of the connecting block 5, the control switch 36 is electrically connected to the fan 11, the top of the movable plate 4 is fixedly connected to two support blocks 1 37 and two support blocks 2 38, and the support block 1 37 is located in front of the support block 2 38, and the two support blocks 1 37 are both embedded with reciprocating screws 39, and the two reciprocating screws 39 respectively pass through the two support blocks 2 38, and the outside of the two reciprocating screws 39 is both sleeved with a sliding seat 40, and the sliding seat 40 is connected to the reciprocating screw 39 through a ball screw pair.

[0050] In order to achieve the purpose of reducing wear, the present device adopts the following technical solution: the reciprocating screw 39 is connected to the support block 1 37 and the support block 2 38 through bearings, and the bearing connection can reduce wear.

[0051] The use process of the present invention is as follows: when the cloth needs to be cut into umbrella pieces, the rolled cloth is placed on the right side of the device, and then the cloth is pulled to be placed on the cutting plate 7, and then the four electric push rods 3 are controlled to work to make the movable plate 4 and the cutter 6 move up and down once, and then the cloth can be cut, so that the cloth is cut into triangles. After cutting, the cloth is pulled so that the end of the cloth contacts the sticking rod 9, and then the electric push rods 3 are controlled again to make the movable plate 4 and the cutter 6 move up and down once, and then cutting can be carried out again, and the cutting work can be continued in this cycle;

[0052] When cutting, the fan 11 is controlled to work so that sufficient suction can be generated. Then, under the action of the pipe 1 34, the shell 12 and the plurality of through holes 10, the cloth can be adsorbed, and the cloth can be firmly adsorbed and fixed on the cutting plate 7. In this way, the cloth can be adsorbed and fixed. In addition, the shell 14 and the filter 15 are designed and stored in the shell 12, which can have a filtering effect. When cutting, the thread ends generated by cutting can be filtered, so that the thread ends can be prevented from entering the inside of the fan 11 and causing damage to the fan 11.

[0053] When the electric push rod 3 moves the movable plate 4 upward, the push rod 1 26 and the piston 1 25 can be moved upward. At the same time, the spring is compressed. Then, under the action of the pipe 2 35 and the pipe 1 34, the piston 1 25 moves upward, which can make the air in the box 1 24 enter the two box 1s 24, thereby making the two pistons 2 30, the sleeve, the piston 3 31, the push rod 2 32, the spring 2 33, the connecting rod 21 and the scraper 22 move forward. When the piston 2 30 moves forward and contacts the inner wall of the front side of the box 2 28, the piston 3 31, the push rod, the connecting rod 21 and the scraper 22 can continue to move forward. When the moving plate 4 and the cutter 6 move downward to continue cutting, the thrust on the push rod 1 26 is released, and then the spring 1 27 and the spring 2 33 rebound to reset the piston 1 25, the piston, the piston 3 31 and other components. In this way, the moving plate 4 moves up and down once to clean the thread ends on the filter 15 once.

[0054] The gear 44 is meshed with the toothed plate 46 once, and the two reciprocating screws 39 rotate, and the reciprocating screw 39 rotates to drive the sliding seat 40 to move forward and backward, and the gear 44 is meshed with the toothed plate 46 once, which can make the sliding seat 40 move forward and backward once, thereby making the moving block 41 and the pressure rod 42 move forward and backward. In this way, the pressure rod 42 can press the button of the control switch 36 when moving up and down, so that the fan 11 can be stopped when the moving plate 4 moves upward, and the fan 11 can be started when moving downward. In this way, when the moving plate 4 moves upward and the fan 11 stops working, the cloth can be spread flat on the cutting plate 7, and the moving plate 4 automatically adsorbs and fixes the flattened cloth when it moves downward.

[0055] When it is necessary to clean the thread ends inside the storage shell 14, pull the pull ring 17 to pull the pull plate 16 and the storage shell 14 out of the shell body 12, and then the thread ends in the storage shell 14 can be cleaned. After cleaning, the storage shell 14 and other components can be directly inserted back into the original path.

[0056] The above are merely preferred embodiments of the present invention. Anyone skilled in the art may modify the present invention using the above-described technical solutions or modify them into equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
