The top of each of the two laying tables 5 is provided with a surface groove 23, and a top plate 24 is arranged in each of the two surface grooves 23. The size of the top plate 24 is the same as the inner size of the surface groove 23, so that no gap is generated and the normal cutting work is not affected. In addition, the design of the top plate 24 can lift the cloth at the approximate middle position of the cloth and make the cloth have a gap space on both sides of the lifted position. In order to utilize the gap space to quickly smooth the cloth, a back plate 28 is fixedly installed on the top of each of the two extension tables 4, and a smoothing rod 32 is slidingly installed on each of the two back plates 28. The diameter of the smoothing rod 32 is small enough to be inserted into the gap space, and the cloth wrinkles can be smoothed by horizontally moving the smoothing rod 32.

[0056] In the above-mentioned mode, in order to lift the middle position of the cloth, two vertical rods 25 are arranged in each of the two inner cavities 22. The top end of each of the two corresponding vertical rods 25 extends into the corresponding surface groove 23 and is fixedly connected with the corresponding top plate 24. Each of the four vertical rods 25 is slidingly connected with the top inner wall of the corresponding inner cavity 22.

A single-axis cylinder 27 is fixedly installed on the bottom of each of the two extension tables 4. An active hole 1 is arranged on each of the two extension tables 4. An active hole 2 is arranged on the bottom of each of the two laying tables 5. Each of the two active holes 1 is in communication with the corresponding active hole 2, and the active hole 2 is in communication with the inner cavity 22, that is, a passage is formed between the active hole 1, the active hole 2 and the inner cavity 22. The output shaft of each of the two single-axis cylinders 27 is located in the corresponding active hole 1, and the output shaft of each of the two single-axis cylinders 27 is matched with the corresponding bottom plate 26. In this way, the output shaft of the single-axis cylinder 27 can be extended by being started, and the bottom plate 26 and the top plate 24 can be lifted, so that the middle position of the cloth can be smoothly lifted.

[0058] In this embodiment,

[0059] After the cloth is placed on the flat table 5, because the overall area of some cloth is large, it is found that it is troublesome to flatten the cloth by manual work to prevent the cloth from wrinkling, and the staff needs to change positions to straighten the wrinkled place. At this time, manual flattening can be abandoned, the output shaft of the single-axis pneumatic cylinder two 27 is first started to extend, the output shaft of the single-axis pneumatic cylinder two 27 is extended and finally contacts the corresponding bottom plate 26, so as to continue to rise against the bottom plate 26, under the connection of the vertical rod 25, the top plate 24 rises against the middle position of the cloth, and a certain arc space gap appears on both sides of the middle position of the cloth with the lifting of the middle position of the cloth;

[0060] Subsequently, the corresponding two motor two is started in positive direction, the output shaft of the two motor two drives the corresponding unidirectional screw two 30 to rotate, then through the thread relationship between the unidirectional screw two 30 and the linkage plate two 31, the two linkage plate two 31 with the corresponding flattening rod 32 are moved towards the direction of the cloth, the two flattening rods 32 are inserted into the arc space gap on both sides, then the corresponding motor three is started, the output shaft drives the bidirectional screw two 34 to rotate, so that the corresponding two linkage plate three 35 move away from each other, so that the two flattening rods 32 move away from each other, and when moving, the cloth is gradually flattened with the horizontal movement of the flattening rod 32, until the two flattening rods 32 move out from both sides of the cloth, the motor two is started in reverse direction, the flattening rod 32 is retracted to the original state, then the motor three is started in reverse direction, the two flattening rods 32 are brought back to the original position.

[0064] S3: the output shaft of the single-axis cylinder one 16 is extended, the T-shaped frame 6 with the two pressing plates 10 is lowered, and the cloth is pressed, then the output shaft of the two double-axis cylinders two 13 is extended, the two cutters 14 are linearly lowered, when the cutter 14 contacts the cloth, the trimming work is started, and finally the trimming is completed;

10. A method of using the fabric edge-cutting device as described in claim 6, characterized in that, Includes the following steps: S1: First, place the two pieces of fabric to be cut on two flat surfaces and manually flatten them to make them wrinkle-free. S2: Adjust the distance between the two pressing plates according to the required width of the fabric. When adjusting, rotate the double-acting screw one. Through the thread relationship between it and the sliding plate, the two sliding plates will move away from each other. During the movement, the staff can observe the position of the sliding plates on the scale. After both sliding plates have moved to the designated position, the distance between the two pressing plates is the required width of the fabric after the edge cutting is completed. S3: Start the output shaft of the single-axis cylinder one to extend, the shaped frame descends with two pressure plates and presses the fabric. Then start the output shaft of the two dual-axis cylinders two to extend, and the two cutters will descend in a straight line. When the cutters contact the fabric, they will start the edge trimming work and finally cut off the fabric. S4: After the cutting is completed, the output shafts of the two dual-axis cylinders are extended, causing the two cutters to move away from each other, pushing the cut fabric scraps to the inclined sliding surfaces on both sides of the base, and then naturally sliding into the receiving cart below. S5: The forward start motor drives the one-way screw to rotate. Through the threaded engagement between the screw and the linkage plate, the two flatbeds begin to move horizontally. Eventually, the flatbed originally located on one of the extension platforms moves to the position of the flatbed originally located on top of the base platform. The flatbed originally located on top of the base platform then moves to the other extension platform. Subsequently, the cutting of the next piece of fabric continues. At the same time, the other piece of fabric that has been cut is removed, and then the next piece of fabric to be cut is placed on it and smoothed out, ready for the next cutting operation. Similarly, after the previous piece of fabric has been cut, the reverse start motor is activated to change the position of the two flatbeds again, and the process of cutting, picking up and placing fabric continues. This process is repeated until all cutting is completed.
