[0002] Cigarette box printing is a crucial step in the tobacco industry, involving multiple aspects such as design, material selection, printing processes, and environmental requirements. Cigarette boxes are created by printing, cutting, and pasting cardboard, and are used to package cigarettes.

[0003] During the printing process, paper tape needs to be conveyed into the printing equipment via conveyor rollers. During this conveying process, the paper tape can shift and deform, leading to process defects. Therefore, those skilled in the art have provided an online monitoring and feedback device for paper deformation to solve the problems mentioned in the background section. Utility Model Content

[0005] Inside the frame, a lead screw is rotatably connected between the limiting roller and the conveying roller. Monitoring mechanisms are symmetrically installed at both ends of the lead screw. Each monitoring mechanism includes a connecting block. The lead screw spirally passes through the connecting block. A limiting groove is fixedly connected above the lead screw inside the frame. The upper end of the connecting block is located inside the limiting groove. A base is fixedly connected below the connecting block. The frame has an opening located between the limiting roller and the conveying roller. The base is located inside the opening. Fixed rods are symmetrically installed on both sides above the base. A rotating plate is rotatably connected to the fixed rod. A laser displacement sensor is installed at the lower end of the rotating plate. A toothed ring is fixedly connected to one side of the upper end of the rotating plate. A rack is fixedly connected to one side inside the frame. The rack is located on the moving path of the toothed ring and can mesh with the toothed ring.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model is designed with a monitoring mechanism that can move back and forth or towards each other on the lead screw, so that the distance between the monitoring mechanisms is adjustable, thus making it suitable for monitoring paper tapes of different widths and having a wide range of applications.

[0013] 2. This utility model is designed with a rotating plate.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-3 In this embodiment, an online monitoring and feedback device for paper deformation is provided, including a frame 1, a paper jamming roller 2 installed above one end of the frame 1, a limit roller 3 rotatably connected inside the frame 1 on one side of the paper jamming roller 2, and a conveying roller 4 rotatably connected inside the frame 1 on one side of the limit roller 3.

[0024] Inside the frame 1, a lead screw 8 is rotatably connected between the limiting roller 3 and the conveying roller 4. Monitoring mechanisms 9 are symmetrically installed at both ends above the lead screw 8. The monitoring mechanism 9 includes a connecting block 92. The lead screw 8 spirally passes through the connecting block 92. A limiting groove 6 is fixedly connected inside the frame 1 above the lead screw 8. The upper end of the connecting block 92 is located inside the limiting groove 6. A base 91 is fixedly connected below the connecting block 92. An opening 11 is provided inside the frame 1. The opening 11 is located between the limiting roller 3 and the conveying roller 4. The base 91 is located inside the opening 11. Fixed rods 93 are symmetrically installed on both sides above the base 91. A rotating plate 94 is rotatably connected to the fixed rod 93. A laser displacement sensor 95 is installed at the lower end of the rotating plate 94. A gear ring 96 is fixedly connected to one side of the upper end of the rotating plate 94. A rack 10 is fixedly connected to one side inside the frame 1. The rack 10 is located on the moving path of the gear ring 96 and can mesh with the gear ring 96.

[0025] In this embodiment, specifically, a motor 5 is fixedly installed on one side of the frame 1, and the motor 5 is fixedly connected to one end of the conveyor roller 4.

[0026] In this embodiment, specifically, a second motor 7 is fixedly installed on one side of the frame 1, and the second motor 7 is fixedly connected to one end of the lead screw 8.

[0027] In this embodiment, specifically, the lead screw 8 has threads at both ends with opposite directions of rotation, and the connecting block 92 is located on threads with different directions of rotation.

[0028] In this embodiment, specifically, the upper inner surface of the base 91 is flush with the inner end surface of the frame 1.

[0029] In this embodiment, specifically, the laser emitted by the laser displacement sensor 95 is directed towards the upper inner surface of the base 91.

[0030] The paper tape released through the paper roller 2 passes under the limiting roller 3 and the conveyor roller 4. Motor 5 is started, driving the conveyor roller 4 to rotate and continuously wind up the paper tape. Motor 7 is started, driving the lead screw 8 to rotate. Because the upper end of the connecting block 92 is restricted by the limiting groove 6, it can only slide inside the limiting groove 6. The rotation of the lead screw 8 causes the connecting blocks 92 to move closer or further apart, which in turn causes the bases 91 to move closer or further apart. Adjusting the spacing of the bases 91 ensures that the edge of the paper tape is below the laser displacement sensor 95. The laser displacement sensor 95 monitors the edge of the paper tape. An alarm device is installed on the frame 1. The frame 1 is connected to the laser displacement sensor 95 via control equipment. When there is significant deformation on the edge of the paper tape, the alarm device will provide a warning.

[0031] When the laser displacement sensor 95 needs repair or replacement, the motor 7 is started, causing the connecting block 92 to move the base 91 closer to the inner wall of the frame 1. When the base 91 moves closer to the inner wall of the frame 1, the rack 10 can be inserted into the base 91 below the gear ring 96. The gear ring 96 rotates under the push of the rack 10, which in turn drives the rotating plate 94 to rotate, so that the lower end of the rotating plate 94 rotates from inside the base 91 to above the base 91 and close to the side of the frame 1, making it convenient for the staff to repair or replace the laser displacement sensor 95.

[0032] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
