Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum foil laminating machines, and particularly relates to an adjustable nickel-chromium hollow worktable for heating aluminum foil laminating films. Background Technology

[0002] Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic plates, and household goods, typically as a packaging material; it is also used as a material for electrolytic capacitors; as an insulation material for buildings, vehicles, ships, and houses; and as decorative gold and silver threads, wallpaper, and decorative trademarks for various stationery printed materials and light industrial products. Among these various uses, packaging material is the most effective way to utilize the performance characteristics of aluminum foil. Aluminum foil is a soft metal film that not only has advantages such as moisture resistance, airtightness, light blocking, wear resistance, aroma retention, and non-toxicity and odorlessness, but also has an elegant silvery-white luster, making it easy to process into beautiful patterns and designs of various colors, thus making it more popular.

[0003] Aluminum foil laminating machines are specialized equipment that use solvent-free adhesives to bond aluminum foil with another composite substrate (film, paper, non-woven fabric, textile fabric, etc.). With the continuous development of enterprises and the constant innovation of new products and processes, this laminating machine, due to its top heating method, has poor drying effect, resulting in slow speed. The laminated products often have high moisture content or film peeling, making it difficult to meet process quality requirements. This not only leads to material waste but also affects the normal supply of orders. The root cause of the problem is the heating method of the drying oven. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable nickel-chromium hollow worktable for heating aluminum foil composite films. This adjustable nickel-chromium hollow worktable combines oil temperature heating and high-temperature air heating. The surface of the nickel-chromium hollow worktable is divided into a medium-temperature zone, a high-temperature zone, and a medium-temperature zone I. By using oil temperature to neutralize the temperature of the medium-temperature zone and / or the temperature of the medium-temperature zone I, temperature regulation and control are achieved. This allows for the drying of aluminum foil composite films of different specifications, improving the drying efficiency of the nickel-chromium hollow worktable.

[0005] To achieve the above objectives, this utility model provides an adjustable nickel-chromium hollow workbench for heating aluminum foil composite films, comprising a nickel-chromium hollow workbench housed within an oven.

The nickel-chromium hollow worktable is equipped with an oil temperature control chamber at the medium temperature chamber, which controls the oil temperature to be lower than the airflow control temperature of the high temperature intake pipe and is used to adjust the temperature of the medium temperature chamber. The oil inlet main pipe and the oil return main pipe are respectively connected to the oil temperature control chamber via oil inlet branch pipes and oil return branch pipes.

[0007] Furthermore, the oil temperature control chamber is located at the bottom of the medium temperature chamber.

A temperature control pipe is connected between the pair of oil temperature control chambers, and multiple temperature control pipes are evenly distributed on the top of the medium temperature chamber.

[0009] Furthermore, the nickel-chromium hollow workbench has a preheating area at the front end of the medium-temperature zone, and a preheating chamber is provided inside the nickel-chromium hollow workbench at the preheating area. The front and rear sides of the preheating chamber are connected to the main oil inlet and the main oil return pipe through the oil inlet branch pipe I and the oil return branch pipe I, respectively.

[0010] Furthermore, the nickel-chromium hollow workbench is equipped with an oil temperature regulating chamber I located at the medium temperature chamber I. The oil temperature is controlled at a temperature lower than that of the high temperature inlet pipe airflow control temperature and is used to regulate the temperature of the medium temperature chamber I. The front and rear sides of the oil temperature regulating chamber I are connected to the main oil inlet pipe and the main oil return pipe respectively through the oil inlet branch pipe II and the oil return branch pipe II.

[0011] Furthermore, the oil temperature control chamber I is located at the bottom of the medium temperature chamber I.

[0012] Furthermore, the oil temperature control chamber I is configured as a pair and located on both sides of the medium temperature chamber I. A temperature control pipe I is connected between the pair of oil temperature control chambers I. The temperature control pipe I is configured as multiple pipes and is evenly distributed on the top of the medium temperature chamber I.

[0013] Furthermore, temperature sensors, temperature sensor I, and temperature sensor II are respectively installed in the oven at the medium temperature zone, the high temperature zone, and the medium temperature zone I to monitor the temperature of the medium temperature zone, the high temperature zone, and the medium temperature zone I.
