Description

Technical Field

[0001] The present invention relates to the technical field of film laminating machines, specifically a plastic packaging film laminating machine. Background Art

[0002] In the field of plastic packaging, the film laminating process is to laminate two or more layers of plastic films together to improve the performance of the packaging, such as enhancing the barrier property, increasing the strength, etc. Therefore, it is widely used in the fields of food packaging, pharmaceutical packaging, and daily necessities packaging.

[0003] However, in actual applications, traditional plastic packaging film laminating machines usually have uneven application of adhesive solution, resulting in poor film laminating effect, and prone to quality problems such as bubbles and delamination, which affect the overall quality and service performance of the packaging. Moreover, in the adhesive discharging link of traditional laminating machines, there is a lack of an effective stirring device, which leads to easy precipitation and stratification of the adhesive solution, making the thickness of the adhesive solution applied on the film inconsistent, and also affecting the laminating quality. Secondly, the transmission structure design of existing laminating machines is not reasonable enough, resulting in poor operation stability of the equipment and high energy consumption. Multiple working components often require multiple independent driving devices, increasing the complexity and cost of the equipment, and at the same time increasing the probability of failures and reducing the production efficiency. In addition, it is difficult to ensure the synchronization between different working components, and problems such as inconsistent film conveying speed and unstable laminating pressure are likely to occur, affecting the laminating accuracy and quality. For this reason, we propose a plastic packaging film laminating machine. Summary of the Invention

This design not only simplifies the transmission structure of the equipment, reduces the complexity and cost of the equipment, but also reduces the probability of failures, improves the stability of equipment operation. Moreover, compared with multiple independent driving devices, the use of a single driving motor reduces energy consumption and achieves the purpose of energy saving.

[0018] 3. For this plastic packaging film laminating machine, when the double-groove driving wheel rotates, the second belt can drive the first winding gear to rotate, and then the winding transmission gear is driven, so that the second winding gear drives the winding roller to rotate synchronously, realizing the synchronous winding of the plastic film after film lamination.

Then, the glue pump 28 transports the glue through the glue discharging pipe 29 to the glue discharging nozzle 31, and the glue discharging nozzle 31 sprays the glue onto the rubber roller group 4.

[0040] In this embodiment, a receiving table 37 is arranged below the winding roller 11. The receiving table 37 is rotatably connected to the winding roller 11, and the winding roller 11 and the receiving table 37 are detachably designed with respect to the film laminating machine frame 1.

[0041] Specifically, through the design of the receiving table 37, it can assist in receiving the material roll after the winding roller 11 has completed winding.

[0044] During operation, first, a plastic film raw material roll to be film combined is sleeved on the outside of the first material roller 2. Then, the free end of the film roll passes through from the upper end of the first guide rod 3, then passes through from the lower end of the rubber roller group 4, then passes through from the upper end of the second guide rod 5, and finally enters the upper ends of the three conveyor rollers 6. At this time, another plastic film raw material roll is sleeved on the outside of the second material roller 7. The free end of the film roll at this time also enters the upper ends of the conveyor rollers 6 after passing through the upper end of the cross plate 8. At this time, the free ends of the two film rolls jointly pass through the upper pressure roller 9 and the lower pressure roller 10 for pressing and winding on the outside of the winding roller 11. At this time, the driving motor 12 is started, and the output end of the driving motor 12 drives the double-groove driving wheel 13 to rotate. By the rotation of the double-groove driving wheel 13, the first belt 14 will be driven to rotate, and thus the slave gear 15 will rotate.

At this time, through the cooperation of the driving gear 25 and the second transmission gear 26, the driven gear 27 will be driven to drive another rotating shaft 23 to rotate, and thus the stirring blades 24 on the outside of the two rotating shafts 23 will stir the adhesive liquid in the adhesive liquid storage tank 22 to improve the uniformity of the adhesive liquid. Then, the adhesive liquid pump 28 pumps the adhesive liquid through the glue outlet pipe 29 to the glue outlet nozzle 31, and the glue outlet nozzle 31 sprays the adhesive liquid onto the rubber roller group 4.

The first transmission gear 16 drives the first rubber roller gear 20 to rotate, and the first rubber roller gear 20 drives the second rubber roller gear 21 engaged with it to rotate, and thus the first rotating rubber roller and the second rotating rubber roller in the rubber roller group 4 extrude and evenly distribute the adhesive liquid sprayed by the glue outlet nozzle 31 and then coat it on the upper surface of the plastic film above. At this time, through the guiding and flipping of the second guide rod 5, the adhesive liquid for coating will bond the free ends of the two film rolls. When the connecting gear 17 near the front end rotates, it will also drive the first transmission gear 16 engaged with it to rotate. By the rotation of the first transmission gear 16, the lower gear 18 will be driven to rotate. By the rotation of the lower gear 18, the upper gear 19 will be driven to rotate, and thus the upper pressure roller 9 and the lower pressure roller 10 will rotate, and the film combining operation will be completed. When the double-groove driving wheel 13 rotates, it will also drive the second belt 32 to rotate. At this time, through the cooperation of the winding first gear 33 and the winding transmission gear 34, the winding second gear 35 can be driven to drive the winding roller 11 to rotate synchronously, and the plastic film after film combination will be wound up.
