The stepper motor 19 drives the bidirectional lead screw 14 to rotate, and the bidirectional lead screw 14 cooperates with the lead screw nut 18 on the left width adjustment plate 16 to drive the left width adjustment plate 16 to move horizontally. The other end of the bidirectional lead screw 14 is connected to the right width adjustment plate 17, the lead screw nut 18, the right mounting short plate 5 and the tight ring 23, and the tight ring 23 is mounted on the outside of the right mounting short plate 5. The two ends of the bidirectional screw rod 14 have opposite thread directions. When the bidirectional screw rod 14 rotates, it pushes the left width adjustment plate 16 and the right width adjustment plate 17 to move closer or farther away. Two guide shafts 24 are symmetrically installed on both sides of the bidirectional screw rod 14. The guide shaft 24 is installed between the left installation short plate 4 and the right installation short plate 5. The left width adjustment plate 16 and the right width adjustment plate 17 are slidably matched with the guide shaft 24 through linear bearings.

[0028] The width adjustment process is as follows: the stepper motor 19 drives the synchronous wheel 20 to rotate, the synchronous wheel 20 drives the bidirectional lead screw 14 to rotate, the bidirectional lead screw 14 cooperates with the lead screw nut 18 to drive the left width adjustment plate 16 and the right width adjustment plate 17 to move horizontally toward each other along the guide shaft 24, and the left width adjustment plate 16 and the right width adjustment plate 17 drive the two clamping components to move horizontally toward each other to adjust the relative distance between the two clamping components.

[0029] The propulsion assembly includes a label clamping connecting plate 41, a swing block 31, a second cylinder 29, and a drive shaft 32 installed on the left width adjustment plate 16 or the right width adjustment plate 17.

[0030] The label clamping connecting plate 41 is installed with a first linear bearing 27 and a second bearing 28. The drive shaft 32 is inserted into the first linear bearing 27. The left width adjustment plate 16 is provided with a long linear groove 25, and the end of the drive shaft 32 can pass through the long linear groove 25, so that the width adjustment component can adjust the spacing between the left width adjustment plate 16 and the right width adjustment plate 17, and the spacing between the two label clamping connecting plates 41. The second cylinder 29 is fixedly connected to the rear mounting long plate 3 through the second bracket 30. The second telescopic rod of the second cylinder 29 is connected to the drive shaft 32 through the drive shaft connecting block 33, and can drive the label clamping connecting plate 41 to slide horizontally along the second slide rail 34.

[0031] The upper end of the swing block 31 is rotatably connected to the label clamping connecting plate 41 through the rotating shaft 39 and the second bearing 28. The oblique groove 35 is located below the slide rail, and a linear cam shaft 38 is installed at the lower end of the swing block 31. The swing block 31 can drive the linear cam shaft 38 to rotate during the rotation process. A third sleeve 37 is installed outside the linear cam shaft 38, and the third sleeve 37 is fixedly connected to the label clamping vertical plate 42.

[0033] like Figure 5As shown, the automatic label tearing device of the utility model includes two label clamping assemblies. Since the two label clamping assemblies have the same structure and are mirror-mounted below the left width adjustment plate 16 and the right width adjustment plate 17, the device describes one label clamping assembly and the other is mirror-mounted. The label clamping assembly is provided with a third cylinder 43 and a fourth cylinder 49. The third cylinder 43 is fixedly mounted on the label clamping vertical plate 42 through a third bracket 45. The third joint 44 is connected to the third cylinder 43 through a third telescopic rod. The other end of the third joint 44 is connected to the telescopic connecting block 46. A horizontally placed third slide rail 48 is provided on the mating surface between the label clamping vertical plate 42 and the telescopic connecting block 46. Two third sliders 47 that cooperate with the third slide rail 48 are provided on the telescopic connecting block 46, so that the telescopic connecting block 46 moves horizontally along the third slide rail 48. The tail of the fourth cylinder 49 is installed on the label clamping base plate 58 through the fourth fixed seat 55, the head of the fourth cylinder 49 is connected to the fourth cylinder joint 50 through the fourth telescopic rod, the fourth cylinder joint 50 is connected to the L-shaped movable clamp connecting block 53 through the first link shaft 51, the other end of the movable clamp connecting block 53 is connected to the fixed clamp connecting block 54 through the second link shaft 52, the bottom surface of the movable clamp connecting block 53 is fixedly connected to the movable label clamp 56, the fixed connecting block is connected to the fixed label clamp 57, the movable label clamp 56 is on the top, and the fixed label clamp 57 is on the bottom, and the two constitute a clamp.

[0034] The label clamping process is as follows: the fourth cylinder 49 works to drive the fourth telescopic rod to retract, pull the fourth cylinder joint 50 to move backward, drive the movable clamp connection block 53 to rotate clockwise around the second chain shaft 52, thereby pulling the movable clamp 56 to lift up, the fixed clamp 57 to abut against the bottom edge of the label, and the clamping claw opens. The third cylinder 43 works to drive the third joint 44 to move horizontally, and the third joint 44 pushes the telescopic connection block 46 to move horizontally along the third slide rail 48, and the clamping claw remains in the open state and moves forward a distance. The fourth cylinder 49 works to drive the fourth telescopic rod to open, push the fourth cylinder joint 50 forward, and push the movable clamp to rotate counterclockwise, thereby pushing the movable clamp 56 and the fixed clamp 57 to close, and the clamping claw clamps the label.

[0035] An L-shaped pressing plate 40 is arranged below the label clamping assembly, and the vertical plate of the pressing plate 40 is fixedly connected to the bottom of the left width adjustment plate 16 or the right width adjustment plate 17. The first cylinder 8 drives the lifting rod 6 to move downward, the lifting rod 6 drives the mounting frame 1 to move downward, the mounting frame 1 drives the left width adjustment plate 16 and the right width adjustment plate 17 to move downward, the pressing plate 40 presses the fabric, and assists the label clamping assembly to clamp the label. The second cylinder 29 drives the driving shaft 32 to move, and the driving shaft 32 drives the label clamping connecting plate 41 to move horizontally, and the fabric is still pressed in the process of lifting the label clamping assembly, so as to assist in completing the label tearing task.

[0036] The label tearing process is as follows: the first cylinder 8 pushes the mounting frame 1 downward, and the pressing plate 40 presses the fabric downward. The stepper motor 19 drives the bidirectional screw 14 to rotate, and the bidirectional screw 14 cooperates with the screw nut 18 to drive the left width adjustment plate 16 and the right width adjustment plate 17 to move toward each other, that is, to adjust the distance between the two label clamping components. The fourth cylinder 49 contracts, pulls the label clamping movable clamp 56 to open, and the label clamping fixed frame presses against the lower edge of the label, and the clamping claw is open at this time. The third cylinder 43 pushes the label clamping component to keep the clamping claw open and move forward along the third slideway for a distance. At this time, the label clamping fixed frame lifts the lower edge of the label. The fourth cylinder 49 pushes the label clamping movable clamp 56 to close, and the clamping claw clamps one side of the label. The second cylinder 29 pushes the drive shaft 32 to move horizontally, drives the label clamping connecting plate 41 to move horizontally, drives the swing block 31 to rotate counterclockwise, thereby driving the label clamping vertical plate 42 to rotate counterclockwise, and the label clamping component moves obliquely upward to separate the label from the fabric, completing the label tearing task.
