Technical Field
[0001] This utility model relates to the field of cutting device technology, and in particular to a product label cutting device. Background Technology
[0002] A product label cutting device is a piece of equipment used to cut and process product labels (such as self-adhesive labels, paper labels, plastic labels, etc.). Its core function is to accurately cut rolls and sheets of label materials according to preset dimensions to meet the needs of subsequent processes such as product labeling and packaging. It is widely used in the label processing stage of industries such as food, medicine, daily necessities, and logistics.
[0003] In the existing technology, the labels are prone to offset when the existing label cutting device is cutting the labels, which causes the cutting position to deviate from the preset trajectory. This results in the loss of control over the label size accuracy. The offset labels are also prone to tearing, rough edges or wrinkles due to uneven force during cutting, which can easily lead to local damage and affect the quality and reliability of the product. Therefore, it is necessary to improve the commodity label cutting device to solve the above problems. Utility Model Content

A fixing ear is fixedly connected to one side of the toothed plate, and a first hydraulic telescopic rod is fixedly connected to the movable frame. The fixing ear is fixedly connected to the telescopic end of the first hydraulic telescopic rod. The first motor drives the threaded rod to rotate, and the rotating threaded rod drives the movable frame and the sliding frame to move.
[0011] Preferably, the cutting assembly includes a semi-circular block fixedly connected to the top of the base, a rotating roller rotatably connected inside the semi-circular block, a second motor fixedly connected to one side of the base, a rubber roller rotatably connected inside the base, a fixed frame fixedly connected to the base, a cutting seat fixedly connected to the base, a second hydraulic telescopic rod fixedly connected inside the fixed frame, a mounting seat fixedly connected to the telescopic end of the second hydraulic telescopic rod, a cutting blade body disposed inside the mounting seat, a mounting bolt threadedly connected inside the mounting seat, a limiting rod fixedly connected to the top of the mounting seat, a limiting plate fixedly connected to the top of the limiting rod, a sliding frame fixedly connected to the output end of the second motor, the mounting bolt contacting the cutting blade body, and the limiting rod slidably connected inside the fixed frame, with the rubber roller rotating under the drive of the second motor.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Please see Figure 1 - Figure 6This utility model provides an embodiment of a product label cutting device, including a base 1, a cutting assembly mounted on the base 1, a movable frame 23 slidably connected inside the base 1, a sliding frame 24 fixedly connected to the top of the movable frame 23, a gear 26 rotatably connected to the movable frame 23, a toothed plate 27 slidably connected inside the sliding frame 24, a limiting frame 28 fixedly connected to the outside of the toothed plate 27, and a rotating roller 29 rotatably connected inside the limiting frame 28. The sliding frame 24 is slidably connected inside the base 1, the toothed plate 27 meshes with the outside of the gear 26, and the limiting frame 28 is slidably connected inside the sliding frame 24. The rotating gear 26 drives the limiting frame 28 to move, and the rotation of the gear 26 drives the toothed plates 27 on both sides to move synchronously in opposite directions, thereby driving the limiting frames 28 on both sides to move synchronously in opposite directions. This device can accurately center and limit the product label according to its width. This effectively prevents product labels from shifting during conveying and cutting. Simultaneously, the rotating roller 29, internally connected to the limiting frame 28, rotates synchronously with the labels during conveying, ensuring both the limiting effect and preventing obstruction or friction damage. This significantly improves the dimensional accuracy of the product labels, reducing cutting errors, tearing, and burrs caused by shifting, ultimately enhancing product quality and reliability. The cutting assembly uses a second motor 33 to drive the rubber roller 34, providing stable power for label conveying. The second hydraulic telescopic rod 37 then drives the mounting base 38 to move the cutting blade body 39 up and down, achieving precise label cutting with controllable cutting force, reducing label breakage during cutting. The mounting bolt 310 facilitates quick installation and replacement of the cutting blade body 39, improving adaptability to cutting labels of different widths. Overall, this improves the precision and efficiency of the cutting operation.
[0019] Please see Figure 2 - Figure 4In this embodiment, the base 1 has a matching groove at the corresponding position of the movable frame 23. The movable frame 23 slides inside the groove of the base 1. The groove design on the base 1 provides a stable sliding guide for the movable frame 23, ensuring that the movable frame 23 does not shift laterally or shake during sliding. This makes the movement of the movable frame 23, the sliding frame 24, the toothed plate 27, and other components more stable, thereby ensuring the accurate positioning of the limit frame 28 on the label and improving the overall stability of the device. The base 1 also has a matching groove at the corresponding position of the sliding frame 24. The sliding frame 24 slides inside the groove of the base 1. The groove on the base 1, which matches the sliding frame 24, allows for smooth movement of the sliding frame 24. The sliding direction is precisely constrained to ensure that the sliding frame 24 maintains a stable trajectory as it moves with the moving frame 23. This prevents positional deviations of components such as the toothed plate 27 and the limiting frame 28 due to offset of the sliding frame 24, ensuring that the limiting frame 28 reliably limits the label. The sliding frame 24 has a groove corresponding to the toothed plate 27, which slides within the groove. The groove on the sliding frame 24 guides the toothed plate 27 to slide stably in a preset direction, preventing jamming or offset when it meshes with the gear 26. This ensures the synchronicity and accuracy of the movement of the limiting frame 28 driven by the toothed plate 27, allowing the two limiting frames 28 to precisely engage and achieve centered limiting of the label, further improving... To improve positioning accuracy, the sliding frame 24 has a corresponding through groove at the corresponding position of the limiting frame 28. The limiting frame 28 slides inside the through groove of the sliding frame 24. The through groove on the sliding frame 24 that matches the limiting frame 28 provides a clear path constraint for the movement of the limiting frame 28, ensuring that the limiting frame 28 will not tilt or misalign when moving with the toothed plate 27. This ensures that the two limiting frames 28 can always maintain a symmetrical state, accurately fit the edge of the label, effectively prevent the label from shifting laterally during conveying and cutting, and ensure the positional stability of the label. A first motor 21 is fixedly connected to one side of the base 1. A threaded rod 22 is fixedly connected to the output end of the first motor 21. The moving frame 23 is threadedly connected to the outside of the threaded rod 22 and the inside of the sliding frame 24. A guide roller 25 is rotatably connected to the toothed plate 27, and a fixing lug 210 is fixedly connected to one side of the toothed plate 27. A first hydraulic telescopic rod 211 is fixedly connected to the movable frame 23, and the fixing lug 210 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 211. A threaded rod 22 is driven to rotate by a first motor 21, and the rotating threaded rod 22 drives the movable frame 23 and the sliding frame 24 to move. By driving the threaded rod 22 to rotate through the first motor 21, the movable frame 23 and the sliding frame 24 are moved to a suitable position. Then, the uncut labels are wrapped around the surface of the rotating roller 32, and then the labels are passed between the guide roller 25 and the sliding frame 24 to improve practicality. The first hydraulic telescopic rod 211 is connected to the toothed plate 27 through the fixing lug 210.The position locking capability of the toothed plate 27 and the limiting frame 28 can be further enhanced based on the gear 26 transmission, preventing the limiting frame 28 from shifting due to force during label conveying and ensuring a long-lasting and stable limiting effect.
[0020] Please see Figure 5 - Figure 6 In this embodiment, the cutting assembly includes a semi-circular block 31 fixedly connected to the top of the base 1, a rotating roller 32 rotatably connected inside the semi-circular block 31, a second motor 33 fixedly connected to one side of the base 1, a rubber roller 34 rotatably connected inside the base 1, a fixing frame 35 fixedly connected to the base 1, a cutting seat 36 fixedly connected to the base 1, a second hydraulic telescopic rod 37 fixedly connected inside the fixing frame 35, a mounting seat 38 fixedly connected to the telescopic end of the second hydraulic telescopic rod 37, a cutting blade body 39 disposed inside the mounting seat 38, a mounting bolt 310 threadedly connected inside the mounting seat 38, a limiting rod 311 fixedly connected to the top of the mounting seat 38, and a limiting plate 312 fixedly connected to the top of the limiting rod 311. The sliding frame 24 is fixedly connected to the output end of the second motor 33. The mounting bolt 310 is in contact with the cutting blade body 39. The limiting rod 311 is slidably connected inside the fixing frame 35. The second motor 33 drives the rubber roller 34 to rotate. The system provides stable power for label conveying, and the material properties of the rubber roller 34 increase friction with the label, preventing label slippage. The second hydraulic telescopic rod 37 drives the mounting base 38 to move the cutting blade body 39 up and down, achieving precise label cutting with controllable cutting force, reducing label breakage during cutting. The mounting bolt 310 facilitates the quick installation and replacement of the cutting blade body 39, improving adaptability to cutting labels of different widths. Overall, the system improves the precision and efficiency of the cutting operation. The mounting base 38 has a through groove at the corresponding position of the cutting blade body 39, and the cutting blade body 39 is set inside the through groove of the mounting base 38. Through the through groove on the mounting base 38, the cutting blade body 39 can be accurately positioned, ensuring that the installation position of the cutting blade body 39 is always consistent, reducing cutting errors caused by blade installation deviations. At the same time, the through groove structure facilitates the quick installation and removal of the cutting blade body 39, simplifies the blade replacement process, reduces operating difficulty, improves adaptability to cutting labels of different widths, and improves overall production efficiency.
[0021] During operation, firstly, the product label to be cut is wound around the rotating roller 32, which is rotatably connected within the semi-circular block 31. Then, the free end of the label is passed sequentially through the gap between the guide roller 25 and the limiting frame 28 within the sliding frame 24, and through the top of the rubber roller 34, allowing it to emerge between the cutting seat 36 and the fixed frame 35. Next, the first motor 21 is started to drive the threaded rod 22 to rotate, causing the movable frame 23, threadedly connected to the outside of the threaded rod 22, and the sliding frame 24 fixed on its top to slide along the groove of the base 1. The label is aligned with the label conveying path. Simultaneously, the first hydraulic telescopic rod 211 is activated to extend, causing the toothed plate 27 to slide inside the sliding frame 24. By engaging the gear 26 on the rotating frame 23, the toothed plates 27 on both sides move synchronously in opposite directions along the slide groove of the sliding frame 24. This, in turn, causes the limiting frame 28 fixed on the outside of the toothed plate 27 to slide synchronously in opposite directions along the through groove of the sliding frame 24, achieving centering and limiting according to the label width. The rotating roller 29 inside the limiting frame 28 moves with the label conveying. The rotation avoids obstructing the conveying process. Then, the second motor 33 drives the rubber roller 34 to rotate, which, together with the rotation of the rotating roller 32, provides continuous and stable conveying power for the label, allowing the label to move at a uniform speed. When the label is conveyed above the cutting seat 36, the second hydraulic telescopic rod 37 in the fixed frame 35 extends, pushing the mounting seat 38 and the cutting blade body 39 fixed in its through groove downwards. With the support of the cutting seat 36, the label cutting is completed. The mounting bolt 310 ensures that the cutting blade body 39 is installed firmly. The limiting rod 311 slides along the fixed frame 35 and limits the movement trajectory of the mounting seat 38 through the limiting plate 312, ensuring cutting accuracy. After the cutting is completed, the second hydraulic telescopic rod 37 retracts, driving the cutting blade body 39 to reset, and the label continues to be conveyed, repeating the above cutting process, thereby achieving continuous and accurate cutting of commodity labels, effectively avoiding deviation, improving cutting quality and efficiency, and by rotating the mounting bolt 310, it is convenient to replace the cutting blade body 39 of different widths, thereby improving the adaptability to cutting commodity labels of different widths.
[0022] Through the above steps, the rotation of gear 26 drives the synchronous reverse movement of toothed plates 27 on both sides, which in turn drives the synchronous reverse movement of limit frames 28 on both sides. This allows for precise centering and limiting according to the width of the product label, effectively preventing it from shifting during conveying and cutting. At the same time, the rotating roller 29 inside the limit frame 28 rotates synchronously with the label conveying, ensuring the limiting effect without hindering the conveying or causing friction damage. This significantly improves the dimensional accuracy of the product label, reduces cutting errors, tearing, burrs, and other problems, and enhances product quality and reliability. This solves the problem that existing label cutting devices are prone to label shifting during cutting, causing the cutting position to deviate from the preset trajectory, resulting in uncontrolled label dimensional accuracy. Furthermore, shifted labels may suffer localized damage such as tearing, burrs, and wrinkles due to uneven force, seriously affecting product quality and reliability.
