[0003] In related technologies, after the cardboard is coated with blister coating oil, it is fixed by a fixing device. A special blister forming machine is used to test its strength. PET or PVC material is used to bond the blister face card and the cardboard together, and hot pressing is performed according to the set temperature, pressure and time parameters. Then, it is torn open to check whether the cardboard can be torn. The area of ​​the torn cardboard is observed and measured, and compared with the qualified standard (the torn area of ​​the cardboard ≥ 80%) to determine whether the strength of the printed product is qualified.

[0004] However, some existing fixing devices use clamps as fixing mechanisms that cannot be adjusted according to the size and shape of the paper, resulting in poor fixing effect on the paper and causing the paper to easily shift position during processing, affecting subsequent inspection.

[0005] Based on this, a fixing device for testing the printing fastness of printed materials is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-4 As shown, the fixing device for testing the printing firmness of printed matter in this embodiment includes a workbench 1, a vacuum forming equipment body 2 fixedly installed on the top of the workbench 1, and support legs 3 fixedly installed at the bottom of the workbench 1 near the four corners.

[0028] A threaded rod 4 is rotatably connected to the bottom inner side of the workbench 1. A drive motor 5 for driving the threaded rod 4 to rotate is fixedly installed at the bottom of the workbench 1. A threaded sleeve 6 is fitted on the surface of the threaded rod 4 and threadedly connected to it. A suction cup 7 is fixedly installed at the top of the threaded sleeve 6. A fixing block is fixedly installed at the rear side of the workbench 1. An air pump 9 is fixedly installed at the top of the fixing block. A connecting hose 10 is fixedly installed on one side of the air pump 9. An adjustment component is provided at the top of the workbench 1.

[0029] In this embodiment, after the cardboard is coated with blister packing oil, it is placed on top of the workbench 1. PET or PVC material is used to bond the cardboard and blister pack together, preparing for a strength test by the main body 2 of the blister packing equipment. The drive motor 5 starts working, driving the threaded rod 4 to rotate. In conjunction with the threaded connection with the threaded sleeve 6, the suction cup 7 moves upward. The cooperation of the lifting block 8 and the lifting groove ensures the stability and accuracy of the lifting movement of the suction cup 7, allowing it to accurately reach the designated position and perform adsorption on the bottom of the cardboard. The adjustment component can be adjusted according to the size of the cardboard, enabling precise clamping of printed materials of different sizes and shapes, further improving the equipment's adaptability to printed materials and enhancing the reliability of equipment operation. Hot pressing is performed according to the set temperature, pressure, and time parameters. Then, the cardboard is torn to check if it can be broken. The result is compared with the qualified standard (cardboard tear area ≥ 80%) to determine whether the strength of the printed material is qualified.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, multiple suction ports 11 are fixedly installed on the top of the suction cup 7. The end of the air pump 9 away from the lifting block 8 passes through the rear side of the workbench 1 and is fixedly connected to the bottom of the threaded sleeve 6. When the suction cup 7 moves to the appropriate position, the air pump 9 starts and draws out the air in the suction cup 7 through the connecting hose 10. A negative pressure is generated at the top of the suction port 11, so that the bottom of the paper and the top of the suction cup 7 are firmly adsorbed and fixed.

[0031] In one embodiment, such as Figure 2 As shown, two lifting blocks 8 are fixedly installed on both the left and right sides of the suction cup 7. The inner side of the worktable 1 is provided with a lifting groove for the lifting blocks 8 to slide up and down, and the inner side of the worktable 1 is provided with an opening for the suction cup 7 to move up and down. The cooperation between the lifting blocks 8 and the lifting groove ensures the stability and accuracy of the lifting movement of the suction cup 7, so that the suction cup 7 can accurately reach the designated position for adsorption operation.

[0032] In one embodiment, such as Figure 3 and Figure 4 As shown, the adjustment assembly includes two adjustment frames 12. A bidirectional threaded screw 13 is rotatably connected to the inner side of the adjustment frame 12. Threaded blocks 14 are fitted on the surface of the bidirectional threaded screw 13 near its front and rear ends and are threadedly connected to it. A clamping member 15 is fixedly installed on the side of the threaded block 14 away from the adjustment frame 12. Due to the threaded transmission, the threaded block 14 on the surface of the bidirectional threaded screw 13 slides back and forth in the moving groove inside the adjustment frame 12, thereby driving the clamping member 15 on one side of the threaded block 14 to move, thereby clamping or releasing the printed matter to meet the inspection requirements of printed matter of different sizes.

[0033] In one embodiment, such as Figure 3 and Figure 4As shown, the front side of the adjustment frame 12 is rotatably connected to a knob 16 that drives the bidirectional threaded screw 13 to rotate. The inner side of the adjustment frame 12 is provided with a moving groove for the threaded block 14 to slide back and forth. The knob 16 is simple and convenient to operate, which makes it easy for the staff to quickly adjust the clamping force and position.

[0034] In one embodiment, such as Figure 3 and Figure 4 As shown, sliding blocks 17 are fixedly installed at the bottom of the adjustment frame 12 near the front and rear sides. A sliding groove is provided on the top of the worktable 1 for the sliding blocks 17 to move left and right. The sliding blocks 17 at the bottom of the adjustment frame 12 can move left and right in the sliding groove on the top of the worktable 1 to adjust the position of the adjustment frame 12.

[0035] In one embodiment, such as Figure 3 As shown, the workbench 1 is equipped with a drive assembly for adjusting the distance between the two adjustment frames 12. The drive assembly enables rapid and precise adjustment of the distance between the adjustment frames 12 without the need for frequent manual adjustments, which greatly improves work efficiency and can adapt to the inspection needs of printed materials of various sizes, thus broadening the applicability of the equipment.

[0036] In one embodiment, such as Figure 3 As shown, in the fixed device for testing the printing firmness of printed matter according to claim 7, the driving component includes a fixed frame 18. The side wall of the fixed frame 18 is fixedly connected to the surface of the worktable 1. An electric telescopic rod 19 is provided through the inner side of the fixed frame 18 and is fixedly connected to it. The power output shaft of the electric telescopic rod 19 is fixedly connected to the side wall of the adjusting frame 12. When it is necessary to adjust the distance between the two adjusting frames 12, the electric telescopic rod 19 starts to work, pushing or pulling the adjusting frame 12 to move left and right on the worktable 1, thereby changing the distance between the two adjusting frames 12 to adapt to printed matter of different sizes.

[0037] The above embodiment discloses a fixing device for testing the printing adhesion of printed materials. After the paper is coated with blister packing oil, it is placed on top of the workbench 1 and bonded to a blister card and cardstock using PET or PVC material. The paper is then prepared for adhesion testing by the main body 2 of the blister packing equipment. The drive motor 5 starts working, rotating the threaded rod 4. This, in conjunction with the threaded connection to the threaded sleeve 6, moves the suction cup 7 upwards, ensuring it accurately reaches the designated position. The vacuum pump 9 starts, extracting air from the suction cup 7 through the connecting hose 10, creating negative pressure at the top of the suction port 11. This ensures a firm adhesion and fixation between the bottom of the cardstock and the top of the suction cup 7. The electric telescopic rod 19 then operates, pushing the adjusting frame 12 left and right on the workbench 1, thereby changing the distance between the two adjusting frames 12. To accommodate printed materials of different sizes, knob 16 drives the bidirectional threaded screw 13 to rotate. Due to the threaded transmission, the threaded block 4 on the surface of the bidirectional threaded screw 13 slides back and forth in the moving groove inside the adjusting frame 12, thereby driving the clamping part 15 on one side of the threaded block 14 to move, thus clamping the printed material. It can adapt to the inspection needs of printed materials of various sizes, broadening the application range of the equipment, and further stabilizing the cardboard. After fixing, the main body 2 of the blister packaging equipment is started, and the cardboard and bonding material are hot-pressed according to the set temperature, pressure and time parameters. After hot pressing, the bonding material is torn open, and the cardboard is checked for tearing. The torn area is compared with the qualified standard (tear area ≥ 80%) to determine whether the printing firmness of the printed material is qualified, thus completing the entire printing firmness test.
