Description

Technical Field

[0001] This utility model relates to the field of packaging material production technology, and in particular to a laminating device for a special packaging material for tackifiers. Background Technology

[0002] Lamination is the process of coating a plastic film with adhesive, bonding it to printed materials on a paper substrate, and then pressing them together with rubber rollers and heated rollers to form a paper-plastic composite product. Lamination machines can be divided into two main categories: in-line lamination machines and pre-coated lamination machines.

[0003] Pre-coated laminating machines greatly simplify the laminating process because they do not require an adhesive heating and drying system. They are also very easy to operate, can be started up immediately, and offer great production flexibility. Furthermore, they produce no solvent odor and no environmental pollution. More importantly, they can completely avoid defects such as bubbles and delamination, and the finished products have extremely high transparency. They have broad application prospects and promotional value.

[0004] Existing packaging materials for tackifiers require lamination and sealing, which is usually done using a pre-coated laminating machine. However, the lamination effect of existing pre-coated laminating machines is generally poor, and subsequent film cutting still requires manual work. Utility Model Content

[0005] The purpose of this invention is to provide a laminating device for packaging materials for tackifiers, which can improve the laminating effect, has stable and reliable processing performance, and can achieve stable and rapid film cutting.

The bottom surfaces of the hot press rollers 7 and rubber rollers 8 are pressed tightly against the surface of the substrate 4. A cooling fan 9 and a pressure plate 10 are also arranged below the mounting frame 5 behind the rubber rollers 8. Both the cooling fan 9 and the pressure plate 10 are mounted below the mounting frame 5 via mounting bases 11. An upward cutting blade 12 is provided inside the limiting block 3.

[0022] Below the mounting frame 5, there are fixed seats 14 corresponding to the hot press roller 7 and the rubber roller 8. Each fixed seat 14 has a receiving groove, and a movable column 13 is movably installed in the receiving groove. The bottom of the movable column 13 is rotatably connected to the hot press roller 7 and the rubber roller 8 respectively. A pressing spring 15 is provided between the fixed seat 14 and the hot press roller 7 and the rubber roller 8 along the outer wall of the movable column 13. Multiple sets of electric heating tubes 16 are also arranged around the inner wall of the hot press roller 7, so that the hot press roller 7 and the rubber roller 8 are always pressed and adhered to the upper surface of the film by the pressing spring 15.

[0023] A preheating roller 17 is also provided on the film between the film receiving roller 6 and the hot pressing roller 7. The preheating roller 17 is fixedly installed at the bottom of the mounting frame 5 and its surface is in contact with the film.

[0024] The air blowing direction of the cooling fan 9 is opposite to the movement direction of the transmission belt 2. Both ends of the cooling fan 9 are rotatably connected to the mounting base 11. The cooling fan 9 can remove heat while also further compressing the film through air pressure.

[0025] A lifting cylinder 18 is provided between the pressure plate 10 and the mounting base 11. The output end of the lifting cylinder 18 is connected to the pressure plate 10, and the lower end of the pressure plate 10 is pressed tightly against the film on the surface of the substrate 4.

[0026] The limiting block 3 is inverted T-shaped. Each set of substrate 4 is locked between adjacent limiting blocks 3. A cutting groove 19 is opened in the limiting block 3. A cutter 12 is movably arranged in the cutting groove 19 perpendicular to the direction of movement of the transmission belt 2. The bottom of the cutter 12 is mounted on the movable seat 20.

[0028] A vision sensor is installed on one side of the base 1 directly below the pressure plate 10. A detection block 24 is installed on one side of each set of limit blocks 3 corresponding to the vision sensor. After the vision sensor detects the detection block 24 at the corresponding position, it stops the transmission belt 2. At this time, the pressure plate 10 presses down to press and limit the film and the substrate 4. Then, the cutter 12 is driven to rise and cut from one side of the film. After the cutting is completed, the cutter 12 descends and retracts.

[0029] A slot 25 is provided in the middle of the lower part of the pressure plate 10 to cooperate with the cutter 12. The slot 25 cooperates with the cutter 12 to cut the film.
