[0002] Self-adhesive label material, also known as self-adhesive label material, is a composite material with paper, film or special material as the surface, adhesive coated on the back, and silicone-coated protective paper as the base paper. When processing self-adhesive label paper, the wide paper is first cut into multiple narrow papers through the paper tape cutting structure, and then the paper bag is cut into rectangular sheet structures for packaging and retail. The existing paper tape cutting structure mainly includes a frame, and a cutting platform arranged on the frame.

[0003] In the existing self-adhesive label production and slitting process, since the labels will be rolled up after slitting, the tension generated when the roll is pulled will cause the self-adhesive label material to be offset, causing the self-adhesive label to be offset when slitting, resulting in uneven slitting of the self-adhesive label and reduced accuracy.

[0004] Therefore, those skilled in the art provide a slitting device for the production of self-adhesive labels to solve the problems raised in the above background technology. Utility Model Content

[0011] As a further solution of the present invention, the number of lasers is consistent with the number of slitting knives, and the right-angle prism is horizontal to the lasers and perpendicular to the slitting knives.

[0012] As a further solution of the utility model, support frames are movably installed at both ends of the adjustable combined roller, and the lower end of the support frame is connected to a lifting cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. A top frame is installed above the frame, and a laser is installed on the top frame. The laser and the slitting blade are set correspondingly to align the knife drop position of the slitting slice. A right-angle prism is installed on the same straight line in front of the laser. The right-angle prism is used to change the optical path of the laser light. The right-angle prism is used to deflect the optical path 90 degrees so that the optical path can be perpendicular to the slitting knife, and then the knife drop point of the slitting knife can be positioned, so that the slitting knife can accurately and evenly cut the self-adhesive label into label strips, avoiding the misalignment of the self-adhesive label and the slitting knife, resulting in inaccurate positioning of the slitting knife on the self-adhesive label material and uneven slitting.

[0015] 2. A resistance piece is installed on the inner wall of the rack. When the self-adhesive label is close to the rack and deviates, the proximity sensor will sense it. At the same time, the resistance piece installed on the inner wall of the rack will push the self-adhesive label back to avoid the self-adhesive label material from being offset. Combined with the positioning of the slitting knife, the slitting accuracy of the self-adhesive label is improved. BRIEF DESCRIPTION OF THE DRAWINGS

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] See also Figure 1 to Figure 4 The embodiment of the utility model provides a slitting device for the production of self-adhesive labels, comprising: a frame 1, both sides of the inner wall of the frame 1 are equipped with a resistance sheet 101, and a telescopic cylinder 102 is connected between the resistance sheet 101 and the inside of the frame 1, a proximity sensor 103 is installed above the resistance sheet 101, a reel 2 is installed on the left side of the frame 1, and a reel 9 is installed on the right side of the frame 1, characterized in that one end of the reel 9 is fixedly connected to a rotating wheel 10, and a driving wheel 11 is installed on one side of the rotating wheel 10, a belt 12 is arranged between the driving wheel 11 and the rotating wheel 10, and a motor 13 for driving is installed on the center line of the rotating wheel 10;

[0023] Specifically, a winding roller 9 and an unwinding roller 2 are respectively arranged on the left and right sides of the frame 1 to unwind and rewind the self-adhesive material. The self-adhesive material starts from the unwinding roller 2 and is finally rewound by the winding roller 9 after slitting, thereby completing the rewinding of the self-adhesive label. The belt 12 is used for transmission, so that the motor 13 drives the driving wheel 11 and the rotating wheel 10 to rotate, thereby realizing the rotation and rewinding of the winding roller 9. The proximity sensor 103 is set so that when the self-adhesive label material deviates and approaches the inner wall of the frame 1, the proximity sensor 103 will sense it, and at the same time, the resistance piece 101 installed on the inner wall of the frame 1 will push the self-adhesive label back, which is conducive to timely correction of the self-adhesive label.

[0024] A top frame 3 is fixedly installed above the frame 1, and a laser 4 is installed inside the top frame 3, a right angle prism 7 is installed on the horizontal line in front of the laser 4, an adjustment combination roller 5 for adjusting the tension force is installed inside the frame 1, a mounting frame 6 is installed below the right angle prism 7, and a mounting sheet 601 is installed on the surface of the mounting frame 6, and a slitting blade 602 is fixed on the surface of the mounting sheet 601;

[0025] The laser 4 and the right-angle prism 7 are located on the same straight line, and the right-angle prism 7 and the slitting knife are located on the same vertical line. The number of lasers 4 is consistent with the number of slitting knives, and the right-angle prism 7 is horizontal to the laser 4 and perpendicular to the slitting knife.

[0026] Specifically, the laser 4 is horizontal to the right-angle prism 7. The laser 4 can use the optical principle of the right-angle prism 7 to turn the optical path of the laser so that the optical path is downward. The downward optical path corresponds to the landing point of the slitting knife, keeping the slitting knife and the optical path in the same straight line. When the slitting knife is offset, it can be discovered and corrected in time, thereby improving the accuracy of slitting.

[0027] The two ends of the adjusting combined roller 5 are movably mounted with support frames 501, and the lower end of the support frame 501 is connected to a lifting cylinder 502;

[0028] Specifically, there are three groups of adjusting combination rollers 5, which are used to adjust the tension of the self-adhesive label material. The rollers on both sides of the adjusting combination rollers 5 are lifted and lowered by the lifting cylinder 502, and cooperate with the rollers set in the middle to press the self-adhesive label material, so as to avoid insufficient tension of the self-adhesive material and reduce the cutting accuracy.

[0029] The working principle of the utility model is as follows: when the utility model is used, the unwinding roller 2 will release the self-adhesive label material, the self-adhesive label material passes from the bottom of the machine top frame 3, passes through the adjustment combination roller 5, and passes from the bottom of the mounting frame 6, is positioned by the positioning pressure roller 8, and is finally rolled up by the winding roller 9. During the slitting process, the light of the laser 4 on the machine top frame 3 will pass through the right-angle prism 7. The optical principle of the right-angle prism 7 is used to turn the optical path of the laser so that the optical path is downward and the optical path can be perpendicular to the slitting knife, so that the landing point of the slitting knife can be positioned, and the slitting knife and the optical path are kept in the same straight line. When the slitting knife is offset, it can be found and corrected in time. Secondly, the rotating wheel 10 is connected to the driving wheel 11 by a belt 12, and the motor 13 drives the driving wheel 11 to rotate, and the belt 12 is used for transmission, so that the motor 13 drives the driving wheel 11 and the rotating wheel 10 to rotate, and the winding roller 9 rotates and rewinds. During the rewinding process, the self-adhesive label material will contact the tip of the slitting knife, and then the self-adhesive label will be cut into strips, and finally rewinded by the rewinding roller 9. When the tension of the self-adhesive label material is insufficient, the lifting cylinder 502 is used to lower and adjust the rollers on both sides of the combination roller 5, and cooperate with the rollers set in the middle to press and flatten the self-adhesive label material. When the self-adhesive label is close to the frame 1 and deviates, the proximity sensor 103 will sense it, and at the same time, the resistance piece 101 installed on the inner wall of the frame 1 will use the telescopic cylinder 102 to push the self-adhesive label back.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
