DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 The label sticker cutting machine with automatic paper feeding shown in the figure comprises a U-shaped base 1, and a conveyor belt 2 is fixedly arranged on the opposite inner wall of the U-shaped base 1. It should be noted that the conveyor belt 2 is an existing device and plays a conveying function, which will not be described in detail here. An operation hole is provided on the side of the U-shaped base 1, and a lifting block 5 is provided above the U-shaped base 1. A lifting mechanism adapted to the lifting block 5 is provided on the U-shaped base 1. A groove is provided at the bottom of the lifting block 5, and two slide bars are installed on the opposite inner wall of the groove. A plurality of slide blocks 6 are slidably sleeved together on the two slide bars, and the bottom of the plurality of slide blocks 6 A cutting knife 7 is installed on each of them, threaded holes are provided on the sides of the multiple sliding blocks 6, locking bolts 8 are threadedly installed in the multiple threaded holes, avoidance holes matched with the locking bolts 8 are provided on the sides of the lifting block 5, locking plates 9 are sleeved on the multiple locking bolts 8, a fixed block 10 is installed on the side of the lifting block 5, two moving holes are provided on the top of the fixed block 10, moving rods 11 are slidably installed on the two moving holes, a moving plate 12 and an insulating pressure plate 13 are respectively installed on the top and bottom of the two moving rods 11, and an elastic mechanism is provided at the bottom of the moving plate 12.

[0023] By means of the above structure, when in use, first place the label sticker on the conveyor belt 2, and then move the slider 6. The movement of the slider 6 will cause the cutting knife 7 and the locking bolt 8 to move. When it moves to the specified position, the locking bolt 8 is rotated to make the locking plate 9 fit with the side of the lifting block 5, so that the slider 6 is fixed, thereby adjusting the distance between the cutting knives 7, which is convenient for cutting stickers of different sizes. When the conveyor belt 2 reaches a certain position, the conveyor belt 2 is stopped first, and the lifting block 5 is lowered through the lifting mechanism. The lowering of the lifting block 5 will cause the moving rod 11 to drop through the fixed block 10, and the lowering of the moving rod 11 will cause the insulating pressing plate 13 descends, when the insulating pressing plate 13 contacts the surface of the sticker, the lifting block 5 continues to move downward, and the lifting block 5 continues to move downward, which will cause the moving rod 11 to move relatively. At the same time, the lifting block 5 moves downward to cut the sticker through the cutting knife 7. When the cutting is completed, the lifting block 5 moves upward, and the lifting block 5 moves upward to cause the cutting knife 7 to move upward. At this time, the moving rod 11 fixes the sticker with the insulating pressing plate 13 under the action of the moving plate 12 and the spring. When the moving plate 12 is reset, the lifting block 5 continues to move upward to cause the insulating pressing plate 1 to move upward, thereby releasing the fixation of the sticker, thereby preventing the sticker from rising with the cutting knife 7 and affecting the next cutting, which is convenient for use.

[0024] like Figure 1-Figure 4 As shown, the lifting mechanism includes a U-shaped block 3 installed on the top of the U-shaped base 1, a motor 15 is installed on the side of the U-shaped block 3, and two rotating rods 16 are rotatably installed on the other side of the U-shaped block 3, one end of one rotating rod 16 is installed on the output shaft of the motor 15, and the two rotating rods 16 are installed through a transmission unit, and the other ends of the two rotating rods 16 are installed with circular plates 17, and the sides of the two circular plates 17 are eccentrically installed on the fixed columns, and the two fixed columns are rotatably sleeved with movable plates 18, and the side of the lifting block 5 is installed with two fixed rods, and the other ends of the two movable plates 18 are respectively rotatably sleeved on the two fixed rods, and a guide unit compatible with the lifting block 5 is provided on the U-shaped block 3. The advantage of such a setting is that through the setting of the motor 15, the rotating rod 16, the circular plate 17, the fixed column, the movable plate 18 and the fixed rod, it is convenient to make the lifting block 5 rise and fall continuously.

[0025] Specifically, the output of the motor 15 will cause the rotating rod 16 to rotate, and the rotation of the rotating rod 16 will cause the circular plate 17 to rotate. The rotation of the circular plate 17 will cause the fixed column to move eccentrically. The eccentric movement of the fixed column will give the fixed rod a rising and falling force through the movable plate 18. The force on the fixed rod will cause the lifting block 5 to rise and fall. The rising and falling of the fixed block 5 will cause the slider 6 to move up and down through the sliding rod. The up and down movement of the slider 6 will cause the cutting knife to move up and down, thereby continuously cutting the label stickers on the conveyor belt 2. At the same time, through the setting of the two circular plates 17, the lifting block 5 can be lifted and lowered more stably.

[0026] like Figure 4As shown, the guide unit includes two mounting holes opened on the top of the U-shaped block 3, telescopic rods 4 are installed in the two mounting holes, lifting plates are installed at the ends of the two telescopic rods 4, and the lifting blocks 5 are installed on the sides of the two lifting plates. The advantage of this arrangement is that a certain guiding effect is played through the arrangement of the telescopic rods 4 and the lifting plates, so that the lifting blocks 5 can move vertically.

[0027] like Figure 4 As shown, the transmission unit includes a transmission cavity opened on the U-shaped block 3, wherein a sprocket 19 is sleeved on one of the rotating rods 16, and one end of the other rotating rod 16 extends into the transmission cavity and is installed with a sprocket 19, and a chain 20 is installed on the two sprockets 19 in meshing relationship. The advantage of such an arrangement is that, through the arrangement of the sprocket 19 and the chain 20, the two rotating rods 16 can rotate simultaneously.

[0028] Specifically, when one of the rotating rods 16 rotates, one of the sprockets 19 will rotate, wherein the rotation of the sprocket 19 will cause the other sprocket 19 to rotate through the chain 20, and the rotation of the other sprocket 19 will cause the other rotating rod 16 to rotate, so that the two rotating rods 16 rotate at the same time.

[0029] like Figure 2 As shown, the elastic mechanism includes two springs 14 installed at the bottom of the moving plate 12, and the other ends of the two springs 14 are installed at the top of the fixed block 10. The advantage of this arrangement is that through the arrangement of the springs 14, when the moving plate 12 is not subjected to force, the moving plate 12 is reset under the action of the springs 14.

[0030] like Figure 2 As shown, a ruler 21 is installed on the side of the lifting block 5, and indicator blocks are installed on the bottom of multiple locking plates 9. The advantage of this arrangement is that the distance between the two cutting knives 7 can be easily observed through the arrangement of the ruler 21 and the indicator block.

[0031] Specifically, when the cutting blade 7 is moved, the locking bolt 8 will also move, and the movement of the locking bolt 8 will cause the locking plate 9 to move, and the movement of the locking plate 9 will cause the indicating block to move, so that the distance between the two cutting blades 7 can be read through the indicating block and the ruler 21.

[0032] like Figure 1 As shown, four supporting legs are installed at the bottom of the U-shaped base 1, and buffer pads are installed at the bottom of the four supporting legs. The advantage of this arrangement is that the setting of the supporting legs facilitates the support of the U-shaped base 1, and the setting of the buffer pads plays a certain buffering role, reducing the impact of vibration on cutting.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
