DETAILED DESCRIPTION

[0024] 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.

[0025] Example

[0026] like Figure 1-5 As shown, a self-adhesive label paper die-cutting machine includes a die-cutting machine body 1, a support plate 2 is fixedly connected to the middle of the inner side of the die-cutting machine body 1, a negative pressure pump 3 is fixedly connected to the upper surface of the support plate 2, an exhaust pipe 4 is fixedly connected to one side of the outer surface of the negative pressure pump 3, a cover body 5 is fixedly connected to one end of the exhaust pipe 4, an exhaust pipe 6 is fixedly connected to the other side of the outer surface of the negative pressure pump 3, and a through hole 7 is opened on the side of the upper surface of the die-cutting machine body 1 close to the cover body 5; fixed plates 8 are fixedly connected to both sides of the upper surface of the die-cutting machine body 1, a bidirectional screw 9 is rotatably connected to one side of the inner side of the fixed plate 8, a first hand wheel 10 is fixedly connected to one end of the bidirectional screw 9, first sliders 11 are threadedly connected to both sides of the outer surface of the bidirectional screw 9, and a baffle 12 is fixedly connected to the lower surface of the first slider 11.

[0027] When in use, the label paper is placed on the upper surface of the die-cutting machine body 1, near the through hole 7, through the arrangement of the negative pressure pump 3, the air extraction pipe 4, the cover body 5, the through hole 7, the bidirectional screw 9, the first slider 11 and the baffle 12. When the negative pressure pump 3 is started, the gas inside the cover body 5 is extracted through the air extraction pipe 4, and then the gas is discharged to the outside through the exhaust pipe 6, so that negative pressure is generated at the through hole 7, thereby fixing the label paper, making it less likely for the label paper to deviate during transportation, making the die-cutting more accurate, and the alignment efficiency and accuracy are high. To ensure the quality of die-cutting, when the label paper is being conveyed, a pulling force is generated under the action of negative pressure, so that the label paper is not easy to loosen or wrinkle during die-cutting, and the die-cutting effect is improved. The first hand wheel 10 is used to control the rotation of the bidirectional screw 9 so that the two first sliders 11 on its outer surface drive the baffle 12 to move, thereby adjusting the distance between the two baffles 12 according to the size of the label paper, which is suitable for label papers of different widths, expanding the use range of the die-cutting machine body 1, and at the same time, the unused through holes 7 are blocked to ensure a good negative pressure state.

[0028] In this embodiment, a guide rod 13 is fixedly connected to a side of the inner side surface of the fixing plate 8 close to the bidirectional screw 9 , and the guide rod 13 is slidably connected to the first sliding block 11 .

[0029] During specific use, through the setting of the guide rod 13, when the first slider 11 moves under the action of the bidirectional screw 9, it slides on the outer surface of the guide rod 13 at the same time, thereby increasing the supporting effect on the first slider 11 and playing a guiding role at the same time.

[0030] In this embodiment, both sides of the outer surface of the die-cutting machine body 1 are fixedly connected with extension plates 14 , and the inner side surface of the extension plate 14 is fixedly connected with a tension roller 15 .

[0031] During specific use, by setting the tension roller 15, the label paper is interlaced on the outer surfaces of the two tension rollers 15, so that the label paper has more tension when being transported, preventing wrinkles during the die-cutting process and ensuring good die-cutting quality.

[0032] In this embodiment, rubber rings 16 are slidably connected to both sides of the outer surface of the tension roller 15 , and a limiting ring 17 is fixedly connected to the outer surface of the rubber ring 16 .

[0033] During specific use, through the setting of the limit ring 17, the rubber ring 16 is slidably connected to the outer surface of the tension roller 15, so that the limit ring 17 can adjust its position under the action of external force, which is suitable for label papers of different sizes, and its applicability is enhanced. Due to the large friction of rubber, the limit ring 17 is not easy to move after adjustment, and its stability and firmness are improved. The two sets of limit rings 17 prevent the label paper from being offset during transportation.

[0034] In this embodiment, a motor 18 is fixedly connected to the top of the inner side of the die-cutting machine body 1 , a rotating rod 19 is fixedly connected to the output end of the motor 18 , and a conveying roller 20 is fixedly connected to the outer surface of the rotating rod 19 .

[0035] During specific use, through the setting of the conveying roller 20, the motor 18 drives the rotating rod 19 to rotate, so that the conveying roller 20 and the pressure roller 25 on its outer surface cooperate with each other to convey the label paper, thereby realizing continuous conveyance of the label paper, improving work efficiency and increasing the automation of the device.

[0036] In this embodiment, a guide groove 21 is formed on the other side of the inner side of the fixing plate 8 , an adjusting rod 22 is rotatably connected to the inner bottom wall of the guide groove 21 , and a second slider 23 is threadedly connected to the outer surface of the adjusting rod 22 .

[0037] During specific use, the adjusting rod 22 is set and rotated to make the second slider 23 on its outer surface move up and down inside the guide groove 21, thereby adjusting the height of the pressing roller 25, which is suitable for label papers of different thicknesses and expands the use range of the die-cutting machine body 1.

[0038] In this embodiment, a support rod 24 is fixedly connected to the inner side surface of the second sliding block 23 , and a pressure roller 25 is rotatably connected to the outer surface of the support rod 24 .

[0039] During specific use, the pressure roller 25 is rotatably connected to the outer surface of the support rod 24 through the setting of the pressure roller 25, and the two ends of the support rod 24 are connected to the two second sliders 23, so that the pressure roller 25 can adjust its position as the second sliders 23 move, thereby pressing the surface of the label paper for conveying. At the same time, the pressure roller 25 and the conveying roller 20 are made of rubber material, which can avoid damage to the label paper during transportation.

[0040] In this embodiment, a second hand wheel 26 is fixedly connected to the top of the adjusting rod 22 .

[0041] During specific use, by setting the second hand wheel 26, the second hand wheel 26 is fixed to one end of the adjusting rod 22, which is convenient for operating and controlling the adjusting rod 22, facilitating hand exertion, and increasing convenience of use.

[0042] Working principle: In use, the label paper is inserted on the outer surface of the two tension rollers 15, so that the label paper has more tension when being transported, and the spacing between the two sets of limit rings 17 is changed to limit the two sides of the label paper. The first hand wheel 10 is used to control the rotation of the bidirectional screw 9, so that the two first sliders 11 drive the baffle 12 to move, thereby adjusting the spacing between the two baffles 12 according to the size of the label paper, which is suitable for label papers of different widths. When the negative pressure pump 3 is started, the gas inside the cover body 5 is extracted through the exhaust pipe 4, and then the gas is discharged outward through the exhaust pipe 6. The label paper is discharged from the part, and negative pressure is generated at the through hole 7, so that the label paper is fixed, so that the label paper is not easily offset during transportation. The label paper passes between the conveying roller 20 and the pressure roller 25, and the second hand wheel 26 is used to rotate the adjusting rod 22, so that the second slider 23 on the outer surface drives the pressure roller 25 to move downward, and the surface of the label paper is pressed tightly. The motor 18 drives the rotating rod 19 to rotate, so that the conveying roller 20 conveys the label paper. At the same time, when the label paper is conveyed, under the action of negative pressure, a pulling force is generated, so that the label paper is not easy to loosen or wrinkle during die-cutting.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
