[0020] (1) The utility model adopts a limit plate. When the automatic laser cutting structure of the textile template machine is actually used, the textile cloth can be laid flat on the conveyor belt, and then multiple groups of iron sheets can be used to press the textile cloth. Multiple groups of soft magnetic sheets can absorb multiple groups of iron sheets to ensure the stability of textile cloth transportation.

The four sets of telescopic springs can reset the two sets of limit plates. When the textile cloth moves, multiple sets of balls roll inside the multiple sets of ball sockets respectively to prevent the multiple sets of balls from affecting the transportation of the textile cloth and moving the two sets of moving plates horizontally. When the two sets of moving plates are moved to the appropriate position, the mounting screws and the four sets of mounting nut threads are used to cooperate with each other, and the operating workers rotate the four sets of mounting nuts clockwise and counterclockwise by hand. When the four sets of mounting nuts are in close contact with the two sets of moving plates, the use position of the two sets of moving plates is fixed. The limit plates are provided with a prompt structure, which can promptly remind the operating workers whether the textile cloth is accidentally moved, thereby improving the practicality of the automatic laser cutting structure of the textile template machine.

[0021] (2) The utility model adopts a plug-in plate and a brush.

The rotating front group of conveying rollers can drive the conveyor belt to rotate, and the rotating conveyor belt can convey textile cloth. During this process, the operator can move a group of plug-in plates to make them sleeved on the side walls of a group of plug rods. When this group of plug-in plates contacts the other side of the inner part of the concave frame, the operator uses multiple groups of connecting screws and multiple groups of connected nut threads to cooperate with each other.

[0040] Working principle:

[0041] When the automatic laser cutting structure of the textile template machine is actually used, the textile cloth can be laid flat on the conveyor belt 10, and then multiple groups of iron sheets 16 are used to press the textile cloth. Multiple groups of soft magnetic sheets 15 can absorb multiple groups of iron sheets 16 to ensure the stability of textile cloth transportation. When the external wires are connected and the preset value of the time control switch is reached, a signal can be sent to the controller. The controller makes the forward and reverse motor 7, the laser head 8 and the drive motor 11 work. The output end of the drive motor 11 drives the frontmost group of conveying rollers 9 to rotate. The rotating frontmost group of conveying rollers 9 can push the conveyor belt 10 to rotate. The rotating conveyor belt 10 can transport the textile cloth. The forward and reverse motor 7 can drive the wire lever 3 to rotate. Since the threads of the wire lever 3 and the lead screw sleeve 4 cooperate with each other, the rotating wire lever 3 can push the lead screw sleeve 4 The rotating lead screw sleeve 4 can drive the laser head 8 to move through the moving block 5. The moving laser head 8 can cut the textile cloth. When the preset value of the time control switch is reached, the controller stops the forward and reverse motor 7, the laser head 8 and the drive motor 11. When the textile cloth is accidentally pulled, it will drive multiple iron sheets 16 to move. Multiple iron sheets 16 can push two sets of limit plates 17. When the two sets of limit plates 17 press two sets of push switches 26 respectively, two sets of buzzer alarms 25 start to work. The operating workers can judge whether the textile cloth is accidentally moved by the sound emitted by the two sets of buzzer alarms 25. Four sets of telescopic springs 23 can reset the two sets of limit plates 17. When the textile cloth moves, multiple sets of balls roll inside multiple sets of ball sockets respectively to prevent multiple sets of balls from affecting the textile cloth. The conveying of the two sets of movable plates 19 is performed by horizontally moving the two sets of movable plates 19. When the two sets of movable plates 19 are moved to the appropriate position, the mounting screw 18 and the four sets of mounting nuts 20 are used to cooperate with each other by thread. The operator manually rotates the four sets of mounting nuts 20 clockwise and counterclockwise. When the four sets of mounting nuts 20 are in close contact with the two sets of movable plates 19, the use position of the two sets of movable plates 19 is fixed. The limit plate 17 is provided with a prompt structure, which can promptly prompt the operator whether the textile cloth is accidentally moved, thereby improving the practicality of the automatic laser cutting structure of the textile template machine. At the same time, according to the above operation, when the driving motor 11 is working, the output end of the driving motor 11 drives the frontmost group of conveying rollers 9 to rotate, and the rotating frontmost group of conveying rollers 9 can drive the conveyor belt 10 to rotate. The rotating conveyor belt 10 can convey textile fabrics. During this process, the operator can move a group of plug-in plates 13 to make them sleeved on the side walls of a group of plug rods 30. When this group of plug-in plates 13 contacts the other side of the inside of the concave frame 1, the operator uses multiple groups of connecting screws 31 and multiple groups of connected nuts 32 to cooperate with each other. The operator manually sleeves a group of connecting nuts 32 clockwise on the side walls of a group of connecting screws 31 to complete the installation of this group of plug-in plates 13. At the same time, the brushes 14 on the upper parts of the remaining groups of plug-in plates 13 can wipe and clean the rotating conveyor belt 10. Through the set plug-in plates 13 and brushes 14, the cleaning structure can be replaced without stopping the conveying work, thereby avoiding affecting the working efficiency of the automatic laser cutting structure of the textile template machine due to the replacement of the cleaning structure.
