[0003] Photolithography positioning technology in cigarette paper printing is a high-precision printing process. It uses lasers to engrave precise patterns or marks on the paper to ensure accurate alignment and positioning of the patterns during the printing process. This technology is particularly suitable for cigarette paper because the printing quality of cigarette packs is crucial to brand image and market competitiveness.

[0004] In the photolithographic printing process of cigarette paper, the paper is precisely transported from one printing unit to the next via rollers. The use of rollers ensures the continuity and stability of the printing operation, which is crucial for maintaining the high efficiency of the entire printing process. However, although the rollers are designed to provide stable transport, they may still cause slight deviations in the paper position during actual operation. Even a small deviation can negatively affect the processing accuracy of the cigarette paper. Because the cigarette paper is in close contact with the rollers and is relatively thin, improper operation during paper position adjustment can easily cause wrinkles or even damage to the paper, thereby affecting the quality of the final product. Therefore, a photolithographic positioning accuracy improvement device for cigarette paper printing is proposed to address the above problems. Utility Model Content

Once the paper roll is detected to be skewed, the servo motor and threaded rotating rod can be activated to quickly adjust and ensure the alignment of the paper roll. This overall movement method effectively avoids local pressure on the paper roll, thereby preventing damage and wrinkles. Attached Figure Description

[0029] Please see Figure 1-7 This utility model provides a technical solution:

[0030] A device for improving the photolithographic positioning accuracy of cigarette paper printing includes a base plate 1 and a material roller 2. The material roller 2 is mounted on the top of the base plate 1, and a tension roller 3 is rotatably connected to one side of the upper end of the base plate 1. A frame 4 is fixedly connected to the top of the base plate 1, and a position sensitive detector 5 is fixedly connected to the bottom of the frame 4. A linear motor 6 is fixedly connected to one side of the upper end of the frame 4, and a printing device 7 is fixedly connected to the bottom of the linear motor 6. A conveyor roller assembly 8 is fixedly connected to the upper end of the base plate 1, and an adjustment assembly 9 is mounted on the upper end of the conveyor roller assembly 8. The conveyor roller assembly 8 includes a vertical frame plate 81, and a shaft rod 82 is rotatably connected to the inner side of the vertical frame plate 81 via bearings. A rail 83 is fixedly connected to the outer side of the shaft rod 82. Limiting ring plates 84 are fixedly connected to the outer sides of the left and right ends of the shaft rotating rod 82. The rail 83 is slidably connected to the inner side of the sliding rail groove 87, which is opened inside the double-layer rotating cylinder 86. The adjustment component 9 includes a servo motor 91. A threaded rotating rod 92 is fixedly connected to the end of the main shaft of the servo motor 91. An adjusting block 94 is spirally connected to the outer side of the threaded rotating rod 92. A wheel groove 95 is opened on the inner side of the lower end of the adjusting block 94. A limiting post 93 is slidably connected to the inner side of the adjusting block 94. An inner hole block 96 is slidably connected to the limiting post 93 on the inner side of the adjusting block 94. A thrust spring 97 is fixedly connected to the top of the inner hole block 96. A rubber wheel 98 is rotatably connected to the inner side of the inner hole block 96.

[0031] As a further implementation of this solution, a bracket is installed on the inner side of the base plate 1 near the material roller 2. The material roller 2 is rotatably connected to the bracket of the base plate 1. A paper roll is sleeved on the outer side of the material roller 2. The paper roll on the material roller 2 is in contact with the bottom end of the tension roller 3. The paper roll on the material roller 2 is located between the conveyor roller assembly 8 and the adjustment assembly 9. The upper end of the paper roll on the material roller 2 is in contact with the bottom end of the rubber wheel 98, and the lower end of the paper roll on the material roller 2 is in contact with the outer side of the double-layer rotary drum 86. This ensures the stability and precise positioning of the paper roll during the printing process and reduces the offset during the printing process.

[0032] As a further implementation of this scheme, there are two conveyor roller assemblies 8 and two adjustment assemblies 9. The stand 4 is located between the two conveyor roller assemblies 8. The bottom of the support structure for the linear motion of the printing device 7 and the stand 4 is fixed, which facilitates photolithography on different parts of the paper roll.

[0033] As a further implementation of this solution, the vertical frame plate 81 has an axle hole on the inner side near the shaft rod 82. The bottom end of the vertical frame plate 81 is fixedly connected to the top end of the base plate 1. The bearing is fixed inside the axle hole of the vertical frame plate 81. The left and right ends of the shaft rod 82 are rotatably connected to the vertical frame plate 81 through the bearing. The shaft rod 82 is composed of multiple cylindrical sections. The rail 83 is rectangular. The rail 83 is fixed at both the top and bottom ends of the shaft rod 82. The sliding rail groove 87 is rectangular. The number of rails 83 is the same as the number of sliding rail grooves 87. The double-layer rotating cylinder 86 is sleeved on the outside of the shaft rod 82. The limiting ring plate 84 is circular. The number of limiting ring plates 84 is the same as the number of return springs 85. The left and right sides of the double-layer rotating cylinder 86 are fixed with return springs 85, allowing the shaft rod 82 to rotate smoothly during the printing process, improving the conveying accuracy of the paper roll, and not affecting the position of the paper roll during the adjustment process.

[0034] As a further implementation of this solution, the adjusting block 94 has a straight hole on its inner side near the limiting post 93, and a threaded hole on its inner side near the threaded rotating rod 92. The outer sides of both ends of the threaded rotating rod 92 are rotatably connected to the inner side of the vertical frame plate 81. The left and right sides of the limiting post 93 are fixedly connected to the vertical frame plate 81. The wheel groove 95 passes through the lower end of the adjusting block 94. Rollers are fixed on the left and right sides of the rubber wheel 98. The inner side of the inner hole block 96 has a shaft hole. The top of the thrust spring 97 is fixedly connected to the inner side of the adjusting block 94. Through the friction between the adjusting block 94, the paper roll, and the double-layer rotating drum 86, the adjusting block 94, the paper roll, and the double-layer rotating drum 86 move simultaneously during adjustment, preventing damage or wrinkles to the paper roll. This provides precise adjustment and positioning of the paper roll during the printing process and prevents the paper roll from shifting.

[0035] Workflow: To improve the positioning accuracy of cigarette paper and prevent damage, one end of the paper roll on feed roller 2 is connected to the existing traction roller. The traction roller moves feed roller 2. As the paper roll on feed roller 2 moves, the tension roller 3, double-layer rotating drum 86, and rubber wheel 98 are all in close contact with the paper roll on feed roller 2. The outer material of the double-layer rotating drum 86 is rubber, and the inner material is metal. Through friction, the tension roller 3, double-layer rotating drum 86, and rubber wheel 98 all rotate. Under the action of the spring force of the thrust spring 97... The inner hole block 96 and rubber wheel 98 are pushed downwards, so that the outer side of the rubber wheel 98 is in close contact with the upper end of the paper roll. The rubber wheel 98 rotates inside the inner hole block 96 and inside the wheel groove 95. The position sensitive detectors 5 at the left and right ends detect the position of both ends of the paper roll. Four position sensitive detectors 5 are set to detect the position of the four corners of the paper roll between the position sensitive detectors 5. If the paper roll is skewed, the servo motor 91 is started to drive the threaded rotating rod 92 to rotate. 92 drives the outer spirally connected adjusting block 94 to move. The adjusting block 94 moves left and right due to the limiting post 93. When the adjusting block 94 moves, because the outer side of the adjusting block 94 is in close contact with the outer side of the inner hole block 96 through the paper roll, the adjusting block 94 will drive the paper roll and the double-layer rotating drum 86 to move in real time through the rubber wheel 98. This overall movement method can prevent damage and wrinkles to the paper roll. The double-layer rotating drum 86 is slidably connected to the outer side of the rail 83 through the sliding groove 87, which plays a role in limiting the movement of the double-layer rotating drum 86. The cylinder 86 causes two return springs 85 to deform, and the two return springs 85 play the role of resetting the double-layer rotating cylinder 86. If the rear end of the paper roll is offset, the servo motor 91 at the rear end is activated. If the front end of the paper roll is offset, the threaded rotating rod 92 at the front end is activated. During the adjustment process, the position of the paper roll is not affected, so that the paper roll between the two conveyor roller assemblies 8 and the adjustment assembly 9 is aligned with the printing device 7, thereby improving the positioning accuracy of the paper roll, ensuring the quality of photolithography on the paper roll, and preventing damage to the paper roll during precise positioning.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
