Description

Technical Field

[0001] This utility model belongs to the field of anti-counterfeiting tape slitting technology, specifically relating to an anti-counterfeiting tape slitting device with a waste recycling structure. Background Technology

[0002] Anti-counterfeiting tape, as an important carrier for the security and protection of product packaging, involves multiple precise processes in its production, including coating, slitting, and winding. In the slitting process, to improve equipment and material utilization, a multi-specification stacking process is typically used. This involves arranging tape panels of different widths on a master roll and then slitting it using a slitting machine. While this process effectively reduces paper wastage, it objectively generates two types of process waste: firstly, edge waste from both sides of the master roll after slitting; and secondly, waste from the gaps between tapes of different specifications, typically with a width controlled within the range of 2-5mm.

[0003] Traditional slitting devices mostly employ continuous waste conveying systems, simultaneously transporting waste and finished tape to the final winding station. This layout has significant drawbacks: First, waste shares a conveying channel with the finished products, necessitating a complex sorting mechanism at the end, increasing the probability of equipment failure. Second, residual pressure-sensitive adhesive in the waste tends to adhere and accumulate during long-distance transport, causing contamination of the guide rollers and tension fluctuations. Furthermore, under subsequent high-speed conveying conditions, dynamic tension fluctuations in the waste tape can easily lead to tape breakage or loosening, severely impacting production continuity. Therefore, this invention proposes a slitting device with a waste recycling structure, enabling online sorting and winding of edge material and interstitial waste during the slitting process. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-counterfeiting tape slitting device with a waste recycling structure, comprising a frame, an inlet end on one side of the frame, an outlet end on the other side of the frame, a platform fixed to the top of the frame, and a conveying roller, a flattening roller, a support roller, and a guide roller sequentially installed on the top of the platform from the inlet end to the outlet end of the frame. Pressure rollers are installed on the top of both the conveying roller and the guide roller, and a traction roller is installed at the bottom of the guide roller. Multiple slitters are installed on the body of the support roller. Supports are fixed on both sides of the outlet end of the frame, and a guide rod is fixed between the two supports. A waste collection assembly is installed on the body of the guide rod.

[0006] As a preferred embodiment of this utility model, the waste collection assembly includes a support base, a gear transmission box fixed to the top of the support base, a first drive motor installed at the power input end of the gear transmission box, and a winding reel fixed at the output end of the gear transmission box.

[0007] As a preferred embodiment of this utility model, a sliding frame is fixed to the bottom of the support base, and the guide rod and the sliding frame are slidably connected and fixed by bolts.

[0008] As a preferred technical solution of this utility model, a second drive motor is fixed at one end of the frame, which is located on the guide roller and the traction roller. The output end of the second drive motor is connected to the guide roller and the traction roller at one end via a sprocket and chain drive.

[0009] As a preferred embodiment of this utility model, an adjusting cylinder is fixed at both ends of the flattening roller and the pressure roller on the top of the frame, and a bearing seat is installed at both ends of the flattening roller and the pressure roller. The bearing seat is slidably connected to the frame, and the output end of the adjusting cylinder is fixedly connected to the bearing seat.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) This utility model greatly reduces the time spent on waste materials and finished tape sharing the same transmission channel by realizing online sorting and winding of edge materials and interstitial waste materials. Moreover, waste material recycling is completed simultaneously during the slitting process, making the entire production process more compact and efficient, significantly increasing the slitting output per unit time, and effectively improving production efficiency.

[0012] (2) This invention avoids the waste material and the effectively slit product sharing the same transmission channel in subsequent processes, eliminating the need for a complex sorting mechanism at the end. This not only reduces the structural complexity of the equipment but also reduces the probability of failure caused by the operation of complex mechanisms. At the same time, it avoids problems such as long-distance transmission and contamination of the guide rollers by residual pressure-sensitive adhesive in the waste material, thereby reducing belt breakage or loosening caused by tension issues, reducing equipment downtime for maintenance, extending the service life of the equipment, and reducing maintenance costs.

A bracket 10 is fixed on both sides of the discharging end 3 of the frame 1, and a guide rod 11 is fixed between the two brackets 10. A waste collection component is installed on the body of the guide rod 11.

[0022] Please see Figure 1-2In order to achieve efficient and orderly online sorting and winding of edge waste and interstitial waste, and improve waste recycling efficiency, in this embodiment, as a preferred technical solution of the present invention, the waste collection component includes a support base 15, a gear transmission box 16 fixed at the top of the support base 15, a first drive motor 23 installed at the power input end of the gear transmission box 16, and a winding reel 17 fixed at the output end of the gear transmission box 16.

[0023] Please see Figure 1-2 In order to flexibly adjust the installation position of the waste collection component according to the location of waste generated after cutting tape of different specifications, in this embodiment, as a preferred technical solution of the present invention, the bottom of the support base 15 is fixed with a sliding frame 18, the guide rod 11 and the sliding frame 18 are slidably connected and fixed by bolts.

[0024] Please see Figure 1 In order to provide a stable and synchronous driving force for the guide roller 8 and the traction roller 9, and to ensure that the finished tape after slitting can be transported smoothly at a constant speed, in this embodiment, as a preferred technical solution of the present invention, the frame 1 is fixed with a second drive motor 19 at one end of the guide roller 8 and the traction roller 9, and the output end of the second drive motor 19 is connected to one end of the guide roller 8 and the traction roller 9 through a sprocket and chain drive.

[0025] Please see Figure 1 In order to facilitate the adjustment of the height of the flattening roller 6 and the pressure roller 22 to adapt to anti-counterfeiting tape master rolls of different thicknesses, and to ensure that the tape maintains a good operating condition during the conveying and flattening process, thereby improving the processing effect, in this embodiment, as a preferred technical solution of the present invention, the top of the frame 1 is fixed with adjusting cylinders 20 at both ends of the flattening roller 6 and the pressure roller 22, and bearing seats 21 are installed at both ends of the flattening roller 6 and the pressure roller 22. The bearing seats 21 are slidably connected to the frame 1, and the output end of the adjusting cylinder 20 is fixedly connected to the bearing seats 21.

[0026] In summary, with the aid of the above-mentioned technical solution of this utility model, the workflow of the anti-counterfeiting tape slitting device with a waste recycling structure starts from the feeding end 2. The unwinding device unwinds the rolled anti-counterfeiting tape master roll, with the unwound end first passing between the conveyor roller 5 and the pressure roller 22 at the feeding end 2, allowing the tape master roll to be smoothly conveyed to the surface of the table 4. During the conveying process, the pressure roller 22 at the top of the conveyor roller 5 applies a certain pressure to ensure the tape remains stable during conveying, avoiding any impact on subsequent processes due to shaking; simultaneously, a pressing pulley is provided at the rear end of the conveyor roller 5 to press the tape master roll firmly onto the table 4.

[0027] After passing through the conveyor roller 5, the conveyor belt reaches the flattening roller 6. The flattening roller 6 is positioned by adjusting cylinders 20 at both ends to accommodate conveyor belt rolls of different thicknesses. Its function is to flatten the conveyed conveyor belt, eliminate wrinkles or bends that may occur during the feeding process, ensure a flat surface of the conveyor belt, and provide a good foundation for the subsequent slitting process.

[0028] The flattened tape then passes through the gap between the bottom of the support roller 7 and the table surface 4. Multiple slitters are installed on the support roller 7. The support plate 12 of the slitter can slide laterally along the support roller 7 and is fixed in a suitable position by bolts, thereby adjusting the spacing of the slitting heads 13 to meet the slitting requirements of different tape specifications. When the anti-counterfeiting tape reaches the slitting position, the clamping cylinder 14 is activated, and its output end pushes the slitter 13 downwards around the rotation point at the bottom of the support plate 12, causing the cutting edge of the slitter 13 to abut against the surface of the tape master roll, thus slitting the tape during the conveying process. After slitting, part of the tape becomes finished tape of different specifications, and the other part becomes edge waste and gap waste.

[0029] After slitting, the finished tape and waste material pass through the gap between the guide roller 8 and the top pressure roller 22 to further stabilize their conveying state. The traction roller 9 at the bottom of the guide roller 8 is connected to the second drive motor 19 at one end of the frame 1 through a sprocket and chain drive. The finished tape is provided with stable traction force by the traction roller 9, which drives the slitting finished tape to continue moving forward.

[0030] At the discharge end 3, the slit edge waste and interstitial waste exit through the gap between the guide roller 8 and the top pressure roller 22. The edge waste on both sides is recycled by the waste collection assembly near the support 10, while the interstitial waste is recycled by the waste collection assembly installed at the center. The waste collection assembly on the guide rod 11 is slidably connected to the guide rod 11 via a sliding frame 18 fixed at the bottom and can be fixed with bolts to allow for flexible position adjustment to accommodate edge waste and interstitial waste recycling at different locations. The power source for the waste collection assembly is the first drive motor 23, which is installed at the power input end of the gear transmission box 16. The gear transmission box 16 transmits power to the winding reel 17 at the output end, causing the winding reel 17 to rotate, thereby realizing online sorting and winding of edge waste and interstitial waste.
