[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A fabric cutting device for a large circular knitting machine, such as Figures 1-3As shown, the device includes a base 1, an upper cutter 2, a lower cutter 3, and a receiving member 4. The base 1 has a first groove 5. The lower cutter 3 is fixedly disposed in the first groove 5 area of ​​the base 1. The upper cutter 2 is slidably disposed on the receiving member 4, with a first pulling member between them. The receiving member 4 is slidably disposed on the base 1, with an elastic member between them. A second pulling member is disposed between the lower cutter 3 and the upper cutter 2. After the fabric roll is wound up, it passes through the base 1 to the receiving member 4 area, where it is supported by the receiving member 4. During this support process, under the influence of gravity, the receiving member 4 descends, thereby driving the lower cutter 3 towards the upper cutter 2 through the second pulling member. This causes friction between the lower cutter 3 and the upper cutter 2, ultimately cutting the fabric and allowing the fabric roll to form an independent unit. Subsequent fabric undergoes a new winding process. After the cut fabric roll is taken away, the upper cutter 2 is removed by the first... The pulling member returns to its initial position, and the receiving member 4 returns to its initial position from the elastic member. There are two sets of the first and second pulling members, which are respectively set at both ends of the upper cutting member 2. The two sets of the first and second pulling members make the movement of the upper cutting member 2 smoother and avoid skewing. The second pulling member includes a pulling belt 6 and a positioning post 7. Positioning blocks 8 are fixedly set at both ends of the pulling belt 6. The two positioning blocks 8 are respectively fixed on the upper cutting member 2 and the lower cutting member 3. The positioning post 7 is rotatably set on the receiving member 4. The setting of the pulling belt 6 and the setting of the positioning post 7 on the receiving member 4 enable the receiving member 4 to pull the upper cutting member 2 by forming a pull on the pulling belt 6 through the positioning post 7 during the movement. The moving speed of the upper cutting member 2 is twice that of the receiving member 4. An angle is formed between the upper cutting member 2 and the lower cutting member 3, so that the fabric can be cut from one side to the other side, and the cutting process is continuous.

[0018] The first pulling member includes a connecting belt 9 and a counterweight 10 fixedly disposed at one end of the connecting belt 9. The end of the connecting belt 9 away from the counterweight 10 is fixedly disposed on the upper cutting member 2. The setting of the counterweight 10 allows the upper cutting member 2 to return to its original position after the fabric roll on the receiving member 4 is pulled away. The receiving member 4 has a second groove 11 for the counterweight 10 to slide. The second groove 11 can limit the counterweight 10, so that it can only slide along the length direction of the second groove 11.

[0019] The receiving component 4 is rotatably equipped with a receiving frame 12. The rotation of the receiving frame 12 is used to push the handling tool so that the fabric roll can be poured out onto the handling tool when the receiving frame 12 is tilted.

[0020] The elastic component is set as a hydraulic puller 13, which has the same structure as the door closer. This is existing technology. Under the pull of the hydraulic puller 13, the receiving component 4 can slowly rise and eventually move to the initial position height. When a roll of fabric enters the receiving frame 12 of the receiving component 4, pressure is formed on the receiving component 4. Through this pressure, the receiving component 4 and the upper cutter 2 are moved in the direction of gravity in sequence, and finally the upper cutter 2 and the lower cutter 3 cut the fabric.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
