Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive label processing technology, and in particular to a self-adhesive label cutting device. Background Technology
[0002] Self-adhesive labels are a composite material consisting of a face material (such as coated paper, PET film, etc.), adhesive, and release liner. Their biggest feature is that they can be directly pasted by simply peeling them off the release liner, without the need for additional glue or water. They are widely used in food packaging, product labeling, logistics tracking, and other fields, and can carry printed graphic information as well as achieve anti-counterfeiting and brand promotion functions.
[0003] During the production and processing of self-adhesive labels, the labels need to be cut into specified widths according to production requirements. During the cutting process, a limiting mechanism is usually used to limit the movement of the self-adhesive labels to prevent the cutting from being skewed due to label displacement. However, the limiting mechanism in the existing cutting device has a relatively fixed limiting distance, making it difficult to limit labels of different widths, thus greatly reducing the cutting flexibility of the cutting device.

[0020] Reference Figure 1-4 A self-adhesive label slitting device includes a fixed platform 1, a support column 2 fixedly connected to the bottom surface of the fixed platform 1, a fixed plate 3 fixedly connected to the left side of the fixed platform 1, a collection box 4 fixedly connected to the inner wall of the fixed platform 1, a fixed frame 5 fixedly connected to the top surface of the fixed platform 1, an electric push rod 6 fixedly connected to the inner wall of the fixed frame 5, a slitting blade 7 fixedly connected to the output end of the electric push rod 6, and a pressing mechanism provided at the output end of the electric push rod 6. The pressing mechanism consists of a limiting plate 8, a limiting shaft 9, a pressure plate 10, and a spring 11. The inner wall of the limiting plate 8 is fixedly connected to the output end of the electric push rod 6, the limiting shaft 9 is slidably connected to the inner wall of the limiting plate 8, the pressure plate 10 is fixedly connected to the bottom end of the limiting shaft 9, and the spring 11 is fixedly connected to the top surface of the pressure plate 10 and the bottom surface of the limiting plate 8. The fixed platform 1 is equipped with a limit component on its top surface. The limit component consists of a limit groove 12, a limit slider 13, and a limit baffle 14. The limit baffle 14 is rectangular and made of metal. The metal limit baffle 14 has higher strength and is less prone to deformation and damage under stress, making it more durable. The limit groove 12 is opened through the top surface of the fixed platform 1. The limit slider 13 is slidably connected to the inner wall of the limit groove 12. The limit baffle 14 is slidably connected to the top surface of the fixed platform 1 and fixedly connected to the top surface of the limit slider 13. This is used to limit the movement trajectory of the label and improve the cutting accuracy. The bottom surface of the fixed platform 1 is equipped with a drive mechanism, and the front surface of the fixed plate 3 is equipped with a traction component.
[0021] Specifically, the drive mechanism consists of a fixed ring 15, a first servo motor 16, a bidirectional threaded rod 17, and a threaded sleeve 18. The fixed ring 15 is fixedly connected to the bottom surface of the fixed platform 1. The first servo motor 16 is fixedly connected to the front surface of the fixed ring 15, and the output end of the first servo motor 16 is rotatably connected to the inner wall of the fixed ring 15. The bidirectional threaded rod 17 is rotatably connected to the inner wall of the fixed ring 15, and the output end of the bidirectional threaded rod 17 is fixedly connected to the output end of the first servo motor 16. The inner wall of the threaded sleeve 18 is threadedly connected to the surface of the bidirectional threaded rod 17, and the threaded sleeve 18 is fixedly connected to the bottom surface of the limiting slider 13. This mechanism is used to drive multiple limiting components to move relative to each other, facilitating flexible adjustment of the limiting distance.
[0022] Specifically, the traction assembly consists of a second servo motor 19, a traction roller 20, an anti-slip pad 21, and transmission gears 22. There are multiple transmission gears 22, and all of them mesh with each other to drive the multiple traction rollers 20 to rotate relative to each other, thereby improving the stability of the traction movement. The second servo motor 19 is fixedly connected to the front of the fixed plate 3, and the output end of the second servo motor 19 is rotatably connected to the inner wall of the fixed plate 3. The traction roller 20 is rotatably connected to the inner wall of the fixed plate 3, and the output end of the traction roller 20 is fixedly connected to the output end of the second servo motor 19. The anti-slip pad 21 is fixedly connected to the inner wall of the traction roller 20, and the inner wall of the transmission gear 22 is fixedly connected to the surface of the traction roller 20. This assembly is used to drive the label to move continuously, facilitating continuous cutting operations.
[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
[0024] In use: First, insert the self-adhesive label between multiple traction rollers 20 and clamp it with multiple anti-slip pads 21. Start the second servo motor 19 to drive the traction rollers 20 and transmission gears 22 to rotate. Through the meshing of multiple transmission gears 22, the multiple traction rollers 20 and multiple anti-slip pads 21 rotate relative to each other, thus pulling the label to slide to the right along the top surface of the fixed platform 1. At the same time, start the first servo motor 16 to drive the bidirectional threaded rod 17 to rotate along the inner wall of the fixed ring 15. Through the threaded connection between the bidirectional threaded rod 17 and multiple threaded sleeves 18, multiple limit sliders 13 and multiple limit baffles 14 slide relative to each other along the top surface of the fixed platform 1, thus adjusting the limit spacing of the label. Start the electric push rod 6 to push the pressure plate 10 downward to contact the label through the limit plate 8 and limit shaft 9, thus pressing down and fixing the label. At the same time, the compression of the spring 11 buffers the downward pressure, and the electric push rod 6 drives the cutting blade 7 to move downward to contact the label, thus cutting the label.
[0025] In summary, this self-adhesive label slitting device, by activating the traction component to pull the label to slide to the right along the top surface of the fixed platform 1, and by activating the drive mechanism to drive the limiting component to slide relative to it, can adjust the limiting distance of the label. Activating the electric push rod 6 to push the pressing mechanism downwards to contact the label can press and fix the label. The electric push rod 6 drives the slitting blade 7 downwards to contact the label, thus slitting the label. This achieves the goal of automatically slitting labels of different widths, avoiding the problem of significantly reduced slitting flexibility caused by the fixed limiting distance of existing slitting devices, and thus solves the problems mentioned in the background art.
