Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for anti-counterfeiting bags. Background Technology

[0002] Anti-counterfeiting bags are a type of packaging bag with anti-counterfeiting features. They are mainly used for the secure storage and transportation of valuables such as cash, jewelry, confidential documents, and evidence. They are primarily used in banks, security companies, retail stores, airport duty-free shops, police stations, prisons, etc. After processing, anti-counterfeiting bags need to be cut to a specific length using a cutting device to facilitate use.

[0003] A search revealed that Chinese Patent Publication No. CN213290443U discloses a shearing device for producing anti-counterfeiting film. The screw sleeve moves downward, causing the bearing sleeve to move downward. The downward movement of the bearing sleeve causes the piston rod to move downward within the through hole. The downward movement of the piston rod causes the limiting plate to move towards the baffle A within the slide groove, thereby limiting and fixing the anti-counterfeiting film to be sheared, ensuring stability during shearing.

[0004] While the shearing device described in the aforementioned patent can ensure stability during shearing, different anti-counterfeiting bags require either cold or hot shearing when shearing. When changing blades, the machine must be stopped, which not only complicates the blade changing operation but also affects work efficiency due to the downtime. Therefore, it is necessary to design a shearing device for anti-counterfeiting bags to solve the above problems. Utility Model Content

The second connecting block is internally threaded with a second screw, and one end of the second screw is rotatably connected to a second blade holder. The hot cutting blade is fixedly connected to the inside of the second blade holder by bolts.

[0012] In order to facilitate the resetting of the pressure plate, as a cutting device for anti-counterfeiting bags according to this utility model, a spring is sleeved at the bottom of the outer surface of the connecting rod, and a nut is threadedly connected to the top of the outer surface of the connecting rod.

[0013] In order to facilitate the adjustment of the roller height, as a cutting device for anti-counterfeiting bags according to this utility model, both sides of the upper surface of the cutting table are fixedly connected to a fixing block, and the inner bottom wall of the fixing block is rotatably connected to an adjusting rod.

[0014] In order to facilitate the pressing and conveying of anti-counterfeiting bags, as a cutting device for anti-counterfeiting bags according to this utility model, the outer surface of the adjusting rod is threadedly connected to a support rod, and both sides of the outer surface of the support rod are slidably connected to rollers.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

Rotating the adjusting rod changes the height of the rollers via the support rod to accommodate anti-counterfeiting bags of varying thicknesses within a certain range. Adjusting the distance between the two rollers accommodates anti-counterfeiting bags of different widths. During the shearing and conveying process, the rollers limit the movement of the anti-counterfeiting bag, preventing deviation during rapid stretching and increasing the quality of shearing.

[0025] Example

[0026] like Figure 1-5 As shown, a cutting device for anti-counterfeiting bags includes a cutting table 1, a hydraulic rod 2 fixedly connected to the middle of the outer surface of the cutting table 1, a concave plate 3 fixedly connected to the output end of the hydraulic rod 2, a fixing frame 4 installed in the middle of the inner side of the concave plate 3, and a motor 5 fixedly connected to the middle of the inner side of the fixing frame 4; a rotating rod 6 fixedly connected to the output end of the motor 5, a gear 7 fixedly connected to the outer surface of the rotating rod 6, a first toothed plate 8 meshing with one side of the outer surface of the gear 7, a cold cutting mechanism 9 fixedly connected to the outer surface of the first toothed plate 8, a second toothed plate 10 meshing with the other side of the outer surface of the gear 7, and a hot cutting mechanism 11 fixedly connected to the outer surface of the second toothed plate 10.

[0027] In practical use, the hydraulic rod 2, gear 7, first toothed plate 8, cold cutting mechanism 9, second toothed plate 10, and hot cutting mechanism 11 are arranged to support the anti-counterfeiting bag. The shearing table 1 supports the anti-counterfeiting bag on a flat platform, making the shearing more stable and even. The conveying end of the hydraulic rod 2 extends and reciprocates, allowing the concave plate 3 to drive the cold cutting mechanism 9 and the hot cutting mechanism 11 to move up and down, thereby performing the shearing operation on the anti-counterfeiting bag. The motor 5 drives the rotating rod 6 to rotate, causing the gear 7 to rotate. The height of the cold cutting mechanism 9 is changed by the first toothed plate 8, and the height of the hot cutting mechanism 11 is changed by the second toothed plate 10, realizing the switching between cold cutting and hot cutting. It can realize the automatic switching operation without stopping the machine to disassemble and install the cutter. The switching can be completed online without stopping the operation, improving the efficiency of the shearing operation. At the same time, the positions of the cold cutting mechanism 9 and the hot cutting mechanism 11 can be adjusted, so that the device can perform shearing operations on anti-counterfeiting bags of different thicknesses within a certain range, expanding the application range of the device.

[0028] In this embodiment, the cold cutting mechanism 9 includes a first connecting block 12 fixed to the outer surface of the first toothed plate 8. The first connecting block 12 is internally threaded with a first screw 13. One end of the first screw 13 is rotatably connected to a first blade holder 14. The inside of the first blade holder 14 is fixedly connected with a cold cutting blade 15 by bolts.

[0029] In practical use, by setting the cold cutting blade 15, the first screw 13 is threaded into the inside of the first connecting block 12, thereby installing the first blade holder 14. Then, the cold cutting blade 15 is fixed inside the first blade holder 14 with bolts, which improves the efficiency of replacement and maintenance. The first blade holder 14 encloses the cold cutting blade 15 to prevent it from breaking after long-term operation and causing injury to the human body.

[0030] In this embodiment, the hot cutting mechanism 11 includes a second connecting block 16 fixed to the outer surface of the second toothed plate 10. The second connecting block 16 is internally threaded with a second screw 17. One end of the second screw 17 is rotatably connected to a second blade holder 18. The inside of the second blade holder 18 is fixedly connected with a hot cutting blade 19 by bolts.

[0031] In practical use, by setting the hot cutting blade 19, the second screw 17 is installed inside the second connecting block 16, thereby installing the second blade holder 18. Then, the hot cutting blade 19 is fixed inside the second blade holder 18 with bolts, which facilitates the installation and disassembly of the hot cutting blade 19, makes it easy to replace when damaged, and is easy to maintain. The hot cutting blade 19 is used to perform hot cutting operations on the anti-counterfeiting bag.

[0032] In this embodiment, guide plates 20 are fixedly connected to both sides of the outer surface of the first toothed plate 8 and the second toothed plate 10. Guide rails 21 are slidably connected to the outer surface of the guide plates 20, and the guide rails 21 are fixedly connected to the fixed frame 4.

[0033] In practical use, through the setting of guide plates 20 and guide rails 21, the two sets of guide plates 20 are fixed on the outer surfaces of the first toothed plate 8 and the second toothed plate 10. When the first toothed plate 8 and the second toothed plate 10 move, the guide plates 20 slide inside the guide rails 21, which improves the reliability of movement and increases the stability during use.

[0034] In this embodiment, support plates 22 are installed on both sides of the inner side of the concave plate 3. A connecting rod 23 is slidably connected inside the support plate 22, and a pressure plate 24 is fixedly connected to one end of the connecting rod 23.

[0035] In practical use, the connecting rod 23 is slidably connected inside the support plate 22 through the setting of the pressure plate 24 to support the pressure plate 24. When the concave plate 3 moves downward under the action of the hydraulic rod 2, the pressure plate 24 presses the anti-counterfeiting bag accordingly, maintaining stability during shearing, improving practicality, and effectively avoiding the occurrence of shearing tilt.

[0036] In this embodiment, a spring 25 is sleeved on the bottom of the outer surface of the connecting rod 23, and a nut 26 is threadedly connected to the top of the outer surface of the connecting rod 23.

[0037] In practical use, the spring 25 and nut 26 are used. The nut 26 is threaded to the top of the outer surface of the connecting rod 23 to limit the connecting rod 23 and prevent it from detaching from the support plate 22. At the same time, changing the position of the nut 26 can adjust the stroke of the pressure plate 24. The spring 25 is compressed when the pressure plate 24 is in use and automatically returns to its original position when not in use, making it easier to reset the pressure plate 24 and facilitate its next use.

[0038] In this embodiment, fixing blocks 27 are fixedly connected to both sides of the upper surface of the shearing table 1, and adjusting rods 28 are rotatably connected to the inner bottom wall of the fixing blocks 27.

[0039] In practical use, the adjusting rod 28 is rotatably connected to the inside of the fixed block 27, while the support rod 29 is threadedly connected to the outer surface of the adjusting rod 28. When the adjusting rod 28 is rotated, the height of the roller 30 can be changed by the support rod 29 to adapt to the use of anti-counterfeiting bags of different thicknesses within a certain range, thus increasing the applicability of the device.

[0040] In this embodiment, a support rod 29 is threadedly connected to the outer surface of the adjusting rod 28, and rollers 30 are slidably connected to both sides of the outer surface of the support rod 29.

[0041] In practical use, the rollers 30 are set up so that two sets of rollers 30 are slidably connected to both sides of the outer surface of the support rod 29. The distance between the two rollers 30 can be adjusted to accommodate anti-counterfeiting bags of different widths. During the shearing and conveying process of the anti-counterfeiting bags, the rollers 30 limit the anti-counterfeiting bags to avoid deviation during rapid stretching and increase the quality of shearing.

[0042] Working principle: In use, the anti-counterfeiting bag is placed on the shearing table 1 for conveying and shearing. The conveying end of the hydraulic rod 2 extends and retracts, making reciprocating motion, which allows the concave plate 3 to drive the cold cutting mechanism 9 and the hot cutting mechanism 11 to move up and down, performing the shearing operation on the anti-counterfeiting bag. The motor 5 drives the rotating rod 6 to rotate, causing the gear 7 to rotate. The height of the cold cutting mechanism 9 is changed through the first toothed plate 8, and the height of the hot cutting mechanism 11 is changed through the second toothed plate 10, realizing the switching between cold cutting and hot cutting. When the concave plate 3 moves downward under the action of the hydraulic rod 2, the pressure plate 24 presses the anti-counterfeiting bag accordingly. The pressure plate 24 remains stable during shearing. The spring 25 is compressed when the pressure plate 24 is in use and automatically returns to its original position when not in use, making it easier to reset the pressure plate 24 for future use. When the adjusting rod 28 is rotated, the height of the roller 30 can be changed through the support rod 29 to accommodate anti-counterfeiting bags of different thicknesses within a certain range. The distance between the two rollers 30 can be adjusted to accommodate anti-counterfeiting bags of different widths. During the shearing and conveying process of the anti-counterfeiting bags, the rollers 30 limit the anti-counterfeiting bags to prevent deviation during rapid stretching and improve the quality of shearing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
