Three first motors are fixedly connected to one side of the connecting cover 2. The first motor can drive the guide roller 3 to rotate, so as to cooperate with the pressure roller 8 to guide the woven bag body 4. The output end of the first motor is fixedly connected to the guide roller 3, and the guide roller 3 contacts the woven bag body 4. First grooves 5 are provided on both sides of the connecting cover 2. A spring rod 6 is fixedly connected in the first groove 5. One end of the spring rod 6 is fixedly connected to a moving block 7. The moving block 7 is rotatably connected to the pressure roller 8. The pressure roller 8 is in contact with the woven bag body 4. One side of the woven bag body 4 is in contact with a connecting roller 9 on one side of the woven bag body 4. The connecting roller 9 provides a limiting effect and provides guidance for the woven bag body 4. One side of the connecting cover 2 is fixedly connected to a blocking cover 10. The blocking cover 10 is fixedly connected to an electric push rod 11. One end of the electric push rod 11 is fixedly connected to a cutter 12. The electric push rod 11 can drive the cutter 12 to move downward and cut the woven bag body 4. Both sides of the blocking cover 10 are fixedly connected to an elastic support rod 13. One end of the elastic support rod 13 is fixedly connected to a contact block 14. The elastic support rod 13 and the contact block 14 cooperate with the heat pipe 15 to be able to It is enough to heat the cutter 12 when it contacts the cutter 12, so that the cutter 12 can complete the cutting when it contacts the woven bag body 4. A heat pipe 15 is evenly and fixedly connected in the contact block 14. The heat pipe 15 is connected to an external power supply through a wire, and the contact block 14 generates heat through the power supply, and heats the cutter 12 when it contacts the cutter 12. Two conveying mechanisms 16 are provided on the bottom side of the connection cover 2. The conveying mechanism 16 includes a roller and a conveyor belt, which can guide the woven bag body 4. A fixed seat 17 is provided between the two conveying mechanisms 16, and the fixed seat 17 is fixedly connected to the guide groove. 18, a spring telescopic rod 19 is fixedly connected in the guide groove 18, and a knife seat 20 is fixedly connected to the upper end of the spring telescopic rod 19. The knife seat 20 corresponds to the cutter 12, and the bottom end of the fixed seat 17 is fixedly connected to an air pump 21. The air pump 21 supplies air through a conduit 22 and an air distribution pipe 23, and then sprays it out through a nozzle 24, so as to cool the contact point between the cutter 12 and the knife seat 20, and avoid hot melting over-distance caused by hot melting. The upper end of the air pump 21 is fixedly connected to a conduit 22, and the upper end of the conduit 22 is fixedly connected to an air distribution pipe 23, and the air distribution pipe 23 is evenly fixedly connected with a nozzle 24.

[0020] Among them, the woven bag body 4 is in contact with the pressure strip 26, and a cutter 12 is arranged between the two pressure strips 26. The pressure strip 26 is fixedly connected to the bottom end of the electric telescopic rod 25, and the electric telescopic rod 25 is fixedly connected to both sides of the bottom end of the baffle 10. By setting the pressure strip 26, the woven bag body 4 can be limited by the extension of the electric telescopic rod 25, thereby improving the stability during cutting.

[0021] Among them, the contact block 14 contacts the bevel bar 27, and the bevel bar 27 is fixedly connected to the upper side of the cutter 12. By setting the bevel bar 27, when the cutter 12 moves upward, the elastic support rod 13 can be prompted to contract, and the contact block 14 can be brought into contact with the cutter 12, and heat can be conducted to complete the cutting of the woven bag body 4.

[0022] Working principle: When the woven bag roll is moved by the guide roller 3 and the pressure roller 8, it passes through the connecting roller 9. At this time, the woven bag roll contacts the conveyor belt on the conveying mechanism 16, and then passes through the gap between the two conveying mechanisms 16. The electric telescopic rod 25 prompts the pressure strip 26 to press down so that the woven bag body 4 stably contacts the fixed seat 17. Then, after the cutter 12 is heated by the contact block 14 and the heat pipe 15, the electric push rod 11 extends to drive the cutter 12 to press down, and the woven bag body 4 and the cutter 12 enter the guide groove 18. Then the air pump 21 draws gas into the conduit 22 and the gas distribution pipe 23, and sprays it evenly through the nozzle 24 to cool the cutting point of the cutter 12.

[0023] Example 2

[0024] Among them, the limiting roller 28 is rotated and connected inside the connecting cover 2, and the limiting roller 28 contacts one side of the woven bag body 4. By setting a driving motor on one side of the limiting roller 28 and driving the limiting roller 28 to rotate, the woven bag body 4 can be moved in cooperation with the conveying mechanism 16.

[0025] Among them, the guide fan 30 is rotated to connect the bracket, and the bracket is fixedly connected in the circular groove 29. The circular groove 29 is located on both sides of the connecting cover 2. By setting the guide fan 30, an air guide structure can be formed, which can guide the wind ejected by the air pump 21 through the nozzle 24, so that the hot air flow can be quickly discharged.

[0026] Working principle: The contact position between the cutter 12 and the woven bag body 4 is cooled by the nozzle 24 to reduce the spread of hot melt of the woven bag body 4, and then the air flow is guided to the two circular grooves 29 by the guide fan 30, which can promote the cooling effect. The conveying mechanism 16 cooperates with the limiting roller 28 to move the cut woven bag body 4 out, and maintain the continuity of the cutting of the woven bag body 4.
