Description

Technical Field

[0001] The utility model relates to the field of aluminum-plating rollers, in particular to a high-efficiency aluminum-plating roller of high-barrier uniaxially stretched PE film vacuum aluminum-plating equipment. Background Art

[0002] Vacuum aluminizing equipment, as one of the key equipment in the production of high-barrier uniaxially stretched PE film, plays a vital role. The aluminizing roller in the vacuum aluminizing equipment is made of precision processing and special materials, and is specially designed for uniformly coating a layer of aluminum on the surface of polyethylene (PE) film. Through vacuum aluminizing technology, the aluminizing roller can vaporize metal aluminum at high temperature and deposit it on the surface of the PE film to form a bright, reflective aluminum layer with good barrier properties. This aluminized film not only improves the appearance of the packaging material, but also greatly enhances its moisture-proof, oxygen-barrier, and heat-insulating properties. It is widely used in the packaging field of food, medicine, daily chemical and other industries, and has become an important means to increase product added value and protect commodity quality.

[0003] For example, patent number CN216473465U is a high-efficiency aluminum-plating roller for vacuum aluminum plating, which belongs to the field of vacuum aluminum plating and includes a cylinder. The left side wall of the cylinder is provided with an opening, and a movable frame is slidably connected to the inside of the opening. The left end of the movable frame extends to the outside of the cylinder, and the outer wall of the movable frame is located on the outside of the cylinder and is fixedly sleeved with a fixing ring. The upper and lower ends of the left side wall of the fixing ring are symmetrically vertically provided with strip holes, and a locking mechanism is fixedly provided between the inside of the two strip holes and the left end of the cylinder. The inside of the movable frame is rotatably connected to a rotating disk through a sealed bearing, and a horizontal fixed shaft is fixedly connected to the middle of the left side wall of the rotating disk, and a horizontal rotating shaft is fixedly connected to the middle of the right side outer wall of the cylinder. The above device is easy to disassemble and assemble during maintenance, saves time and effort, and has high efficiency, increases the unit contact area between the vacuum aluminum-plating roller and the cooling channel, improves the cooling effect, and ensures the printing quality, but the following deficiencies still exist.

[0004] The aluminizing roller in the above patent document cools the roller down by providing a cooling coil inside and injecting a coolant into the coil. However, the structure of the existing aluminizing roller is relatively simple. When the aluminizing roller conveys the PE film, the PE film has great toughness, which can easily cause the PE film to deform, thereby causing the PE film to shift when moving. As a result, the coating thickness of the PE film is not uniform during the aluminizing process, thereby affecting the aluminizing quality. Therefore, an efficient aluminizing roller for high-barrier uniaxially stretched PE film vacuum aluminizing equipment is proposed to solve the above problems. Utility Model Content

[0010] As a technical solution of the utility model, bearing mounting bosses for limiting are symmetrically fixed at both ends of the central axis of the aluminum-plated roller, so that the bearing sleeve can be installed outside the bearing mounting bosses.
