[0058] Reference Figure 1 The bed flag seam cutting device may further include an L-shaped frame 7, which is located between the first cutting component 41 and the second cutting component 42, and the height of the L-shaped frame 7 is lower than the first supporting platform 416 and the second supporting platform 426. When the first cutting component 41 and the second cutting component 42 of the bed flag seam cutting device cut the cloth strips at the same time, the suction cup 22 no longer provides suction to the cloth strips, and the cut cloth strips will fall onto the L-shaped frame 7, which is convenient for temporary storage and recovery of the desired finished products.

[0059] The implementation principle of this embodiment is: the operator places the rolled cloth strips at the end of the guide rail platform 6, the operator pulls out the cloth strips, and after being guided by the cloth guide roller 11, the cloth strips are laid flat on the guide rail platform 6, and the cloth strips are passed through the upper pressing roller 12, the pressing plate 13 and the limiting rod 14 in turn, and are laid flat on the guide rail platform 6. The upper pressing roller 12 and the pressing plate 13 flatten the cloth strips to prevent the cloth strips from wrinkling or tangling.

[0060] When performing the first cutting, the cloth strips need to be pulled and placed on the first supporting platform 416 to improve the first cutting quality and reduce cutting waste.

[0061] After the cloth strip is placed on the guide rail platform 6, the device is started, the driving motor 31 drives the conveyor belt 32 to move, the cloth suction assembly 2 moves to the top of the cloth strip, and the lifting cylinder 28 drives the mounting plate 21 to move vertically downward. When the suction cup 22 contacts the cloth strip, the negative pressure pump 24 starts to work, and air is pumped to the suction cup 22 through the air pipe 23, and the cloth strip is sucked up by the suction cup 22.

[0062] The lifting cylinder 28 drives the mounting plate 21 to move vertically upward, and sucks the cloth strip from the guide rail platform 6. It does not need to be lifted very high, just to reduce the friction between the cloth strip and the guide rail platform 6. The driving motor 31 drives the conveyor belt 32 to move, and the cloth suction component 2 moves to the cutting component 4. By observing the positions of the first identification line 213 and the second identification line 214, it is ensured that the first avoidance groove 211 is located above the first give-way opening 417, and the second avoidance groove 212 is located above the second give-way opening 427.

[0063] The lifting cylinder 28 drives the mounting plate 21 to move vertically downward, pressing the cloth strip on the surfaces of the first bearing platform 416 and the second bearing platform 426; the first cylinder 415 drives the first mounting seat 412 to move along the first guide rail 411, the first mounting seat 412 drives the first body 413 to move, the first cutter head 414 on the first body 413 enters the first clearance opening 417, and the bevel of the cloth strip is cut; the second cylinder 425 drives the second mounting seat 422 to move along the second guide rail 421, the second mounting seat 422 drives the second body 423 to move, the second cutter head 424 on the second body 423 enters the second clearance opening 427, and the bevel of the cloth strip is cut; the first cylinder 415 and the second cylinder 425 are connected in parallel, and the bevel of the cloth strip is cut at the same time. After the cutting is completed, the first cutter head 414 and the second cutter head 424 return to their original positions under the action of the first cylinder 415 and the second cylinder 425.

[0064] After the cutting of the bevel of the fabric strip is completed, the negative pressure pump 24 stops working, the suction cup 22 no longer has suction force on the fabric strip, and the cut fabric strip falls under the action of gravity and falls onto the L-shaped frame 7. In addition, the lifting cylinder 28 drives the mounting plate 21 to move vertically upward, so that the suction cup 22 does not conflict with the surface of the first bearing platform 416 and the second bearing platform 426.

[0065] The driving motor 31 reverses, driving the conveyor belt 32 to move, and the cloth suction component 2 moves back to the top of the initial cloth suction position. Since the cloth strips are continuous, the above-mentioned movement method is repeated to realize multi-section cutting of the rolled cloth strips. When a section of cloth strips is cut, the pressing plate 13 exerts a certain pressure on the cloth strips to prevent the cloth strips waiting to be cut from falling from the guide rail platform 6 under the action of gravity, thereby realizing automated cutting, improving work efficiency, and also improving the cutting quality.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
