Description

Technical Field

[0001] This utility model relates to the field of film coating conveying structure technology, and specifically to a film coating machine conveying structure. Background Technology

[0002] In modern packaging, printing, and other industries, lamination and transportation are crucial production processes, and their quality and efficiency have a significant impact on the quality of the final product and the economic benefits of enterprises. During the lamination process, the roller is the core component for achieving the bonding and transfer of the film to the substrate, and the roller temperature directly determines the physical properties of the film and the lamination effect.

[0003] Traditional rollers typically use natural or air cooling to control temperature during the lamination and transport process. Natural cooling relies on ambient heat dissipation, resulting in a slow cooling rate that struggles to quickly respond to drastic temperature changes during production. This leads to roller temperatures remaining at high levels for extended periods, causing the film to soften, deform, and wrinkle, severely impacting lamination quality. While air cooling is an improvement over natural cooling, it is still constrained by factors such as ambient temperature and airflow, resulting in lower temperature control precision and failing to meet the lamination requirements of temperature-sensitive specialty films.

[0004] Meanwhile, sustained high temperatures accelerate the aging and wear of rollers and related components, increasing equipment failure rates, shortening equipment lifespan, and raising maintenance costs and equipment upgrade investments for enterprises. Furthermore, high-temperature environments worsen workshop working conditions, affecting the health and work efficiency of operators and posing certain safety hazards. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a conveying structure for a laminating machine, which can effectively solve the problems in the existing technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a conveying structure for a laminating machine, including a base frame and a mounting frame disposed at the top of the base frame. A drive motor is disposed inside the base frame. Conveying rollers are fixed inside and at the top of the mounting frame via bearing seats. A tensioning device is fixed on one side of the mounting frame. Both ends of each set of conveying rollers are connected to an air inlet pipe. The tensioning device includes a positioning plate and a deflection plate. A square groove is formed in the middle of the positioning plate, and the deflection plate is disposed on the mounting frame via a positioning pin at the bottom. A tensioning wheel is fixed at the top outer side of the deflection plate. A positioning plate is fixed on the back of the mounting frame, and the positioning plate and the deflection plate are fixedly connected by a positioning screw.

[0009] Furthermore, the conveying roller has a hollow structure with a hollow interior. Both sides of the conveying roller are fixedly connected to connecting rods. A driven tooth is fixedly sleeved on the outer side of each set of connecting rods. The driven tooth and the tensioning wheel are connected by a belt for transmission.

[0010] Furthermore, one end of the belt is connected to the output end of the drive motor, and the positioning plate is fixed to the mounting bracket by a pin. With the tensioning device provided, the user can adjust the tension of the belt as needed. The user can deflect the deflection plate to one side through the positioning pin structure at the bottom to adjust the position of the tensioning wheel, thereby adjusting the tension of the belt.

[0011] Furthermore, locking nuts are fitted on the outer sides of the positioning pin, pin shaft, and positioning screw; after reaching the designated position, the user fits the positioning screw into the slot on the positioning plate and fixes it with the nuts to achieve position fixation of the tensioning wheel and prevent it from shifting.

[0012] Furthermore, both connecting rods are hollow structures, and the front end of the air intake pipe is sleeved on the inner side of the connecting rod.

[0013] Furthermore, the positioning plate has multiple sets of slots; by setting a hollow conveyor roller structure, the conveyor roller is connected to an external air source through an external air inlet pipe during film coating and transportation, achieving rapid and precise temperature control. During film coating and transportation, excessively high temperatures can easily lead to problems such as film softening and deformation, wrinkles, or uneven stretching. This conveyor roller can stably control the surface temperature of the roller within a suitable range, avoiding film material deterioration due to excessive temperature, ensuring smooth coating without bubbles, and effectively improving the appearance quality and yield of the finished film.

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This utility model, through its tensioning device, allows users to adjust the belt tension as needed. Users can deflect the deflection plate to one side via the positioning pin structure at the bottom to adjust the position of the tensioning wheel, thereby adjusting the belt tension. After reaching the designated position, the user can fit the positioning screw into the slot on the positioning plate and fix it with a nut to limit the position, thus fixing the tensioning wheel and preventing it from shifting.

[0016] In this device, a hollow conveyor roller structure is used. During the lamination process, the conveyor roller is connected to an external air source via an external air inlet pipe, enabling rapid and precise temperature control. Excessive temperature during lamination transport can easily lead to film softening, deformation, wrinkles, or uneven stretching. This conveyor roller can stably control the roller surface temperature within a suitable range, preventing film material deterioration due to overheating, ensuring smooth lamination without bubbles, effectively improving the appearance quality and yield of the finished product. Stable roller temperature reduces downtime caused by temperature anomalies, making the lamination transport process smoother and improving overall production efficiency. The water-cooled roller, through effective temperature control, reduces the risk of component damage due to thermal stress, decreases the frequency of mechanical failures, lowers equipment maintenance costs, extends the overall service life of the equipment, and saves companies money on equipment upgrades.
