[0063] like Figure 2-Figure 5 and Figure 8-Figure 10 As shown, based on the above embodiment, this embodiment provides the following method for preparing an antibacterial fabric 9:

[0064] Because when sealing the cut position of the antibacterial fabric 9, the antibacterial fabric 9 cannot be compressed and attached in time due to poor sealing effect, which makes the cutting unstable and easily causes scraps to be discharged from the cut, affecting the normal production and preparation of the antibacterial fabric 9;

[0067] When the antibacterial cloth 9 is cut by the covering and cutting mechanism 8, an incision will be produced. Through the continued movement of the covering and cutting mechanism 8, the fixed column 9b pulls the third diaphragm 9a out from the inside of the covering and cutting mechanism 8 and fits on the first diaphragm 5 to close the incision. This can not only maintain a negative pressure inside the antibacterial cloth 9, but also prevent the debris produced by the cutting of the antibacterial cloth 9 from being discharged from the incision, thereby further ensuring the stability of the cutting of the antibacterial cloth 9.

[0079] The working principle and use process of the present invention:

[0080] S1, parallel weaving;

[0081] S1.1, drawing;

[0082] The polypropylene particles are transformed into polypropylene filaments by the equipment, and 8 polypropylene filaments are introduced into the drawing frame for merging, and 8 cotton strips are also merged, and then the merged polypropylene filaments and cotton strips are respectively stretched and thinned;

[0083] S1.2, twisting;

[0084] Then the combined polypropylene filaments and cotton strips are introduced into the twisting machine for twisting, and the polypropylene filaments and cotton strips are respectively wound on bobbins after they have twist and strength;

[0085] S1.3, remove impurities;

[0086] The twisted polypropylene filaments and cotton strips are introduced into the winding machine, rewound into a bobbin shape, and then impurities in the polypropylene filaments and cotton strips are eliminated;

[0087] S1.4, weaving;

[0088] The polypropylene filaments and cotton strips are wound in parallel on a warp beam, and the warp beam is passed through a shuttle guide on a shuttle loom to interweave the polypropylene filaments and cotton strips to form a grey fabric, and the grey fabric is formed into a double-layer structure, which is divided into a base fabric layer 91 and a fluff layer 92;

[0089] S2, the grey cloth is sequentially passed through a high temperature dyeing device - a high temperature fiber opening device - a high temperature shaping device - a high temperature drying device - a forming and rolling device to obtain an antibacterial cloth;

[0090] S3, automatic cutting;

[0091] The antibacterial fabrics 9 are stacked together and transported to a cutting device for cutting into pieces;

[0092] Laying the stacked antibacterial cloth 9 flat on the cutting device, separating and sealing the antibacterial cloth 9, and then shrinking the antibacterial cloth 9 with negative pressure;

[0093] according to Figure 2-Figure 10 The antibacterial cloth 9 is stacked on the vacuum plate 6, and then the first membrane 5 is pulled out from the first roll 3, and is laid flat to cover the antibacterial cloth 9, and the first membrane 5 is attached to the side of the antibacterial cloth 9 and the vacuum plate 6, and then the air pump 4 is started to extract the air inside the vacuum plate 6. Since the first membrane 5 covers the antibacterial cloth 9, the vacuum plate 6 extracts the air inside the antibacterial cloth 9, shrinks the antibacterial cloth 9 and makes the first membrane 5 attached to the antibacterial cloth 9;

[0094] The cutting tool of the mobile cutting device cuts the antibacterial fabric 9, and separates and seals the cutting position again, so that the antibacterial fabric 9 continues to shrink under negative pressure until the antibacterial fabric 9 is cut;

[0095] When the cutting tool is moved, the motor 822 is started to make the gear 823 rotate inside the slider 821 and mesh with the rack 72, so that the slider 821 slides on the top surface of the first side support plate 7, and at the same time, the limit block 824 slides in the groove of the guide plate 71, so that the second side support plate 813 drives the roller 814 to roll on the first diaphragm 5 attached to the side wall of the antibacterial cloth 9, and presses the first diaphragm 5 against the side wall of the antibacterial cloth 9. At the same time, the first diaphragm 5 is pressed against the vacuum plate 6 by the pressing plate 815, so that the antibacterial cloth 9 remains sealed and tightened;

[0096] When the slider 821 drives the guide rod 83 to move and the cutting assembly 84 reaches the upper part of the cutting position of the antibacterial cloth 9, the electric cutting knife 848 is first started to rotate inside the pressing block 847, and then the pneumatic rod 844 is started to pull the push plate 842 to move downward, and the pressing block 847 is pushed downward by the guide rod 843 to guide the movement, so that the electric cutting knife 848 cuts the antibacterial cloth 9 and the first diaphragm 5, and at the same time, the body 841 is started to move on the guide rod 83, so that the electric cutting knife 848 moves and cuts;

[0097] After the cutting is completed, the slider 821 is continuously moved to move the film covering assembly 86 to the top of the incision, and the two electric rollers 867 are started to rotate to clamp one side of the second diaphragm 865, and under the rotation of the electric rollers 867, the second diaphragm 865 is completely pulled out from the storage box 862, and under the friction effect of the second diaphragms 865 being folded and pressed tightly together, the next second diaphragm 865 inside the storage box 862 is pulled out from the storage box 862, until the second diaphragm 865 is flattened on the first diaphragm 5 at the incision position by the two electric rollers 867, and the side of the next second diaphragm 865 is clamped between the two electric rollers 867;

[0098] Finally, as the slider 821 continues to move and under the positioning and pulling of the fixed column 9b, the third diaphragm 9a is pulled out from the second roll 852 of the film output frame 85, and is turned by the turning roller 854, so that the third diaphragm 9a is laid flat on the top surface of the first diaphragm 5 and the second diaphragm 865, and the incision position is completely closed, so that the inside of the antibacterial cloth 9 remains in a vacuum-tight state, which facilitates the slider 821 to continue to move the cutting assembly 84 to continue cutting the antibacterial cloth 9.
