Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil lunch box forming, and in particular to an aluminum foil lunch box forming system. Background Art

[0002] Aluminum foil lunch boxes are a widely used tableware. They can be divided into two types: wrinkled and wrinkle-free. They are often called tinfoil lunch boxes in China. They are cold-rolled or hot-rolled into aluminum foil mother rolls, and then cold-stamped in one go by special equipment and molds. Because the production process requires more than 40 tons of punching force and a high punching frequency, the equipment, molds and aluminum foil surfaces generate heat due to friction. If the heat is not dissipated in time, the service life of the equipment and molds will be greatly reduced. In addition to cooling and dissipating the equipment and molds, some processing plants currently use spray guns to spray edible grade oil on aluminum foil to form a thin layer of oil film on the surface of the aluminum foil. This oil film plays a role in heat insulation, reduces direct heat transfer and frictional heating between the mold and the aluminum material, and adheres to the mold and equipment to increase heat exchange, further promoting cooling. However, this method will cause some oil mist to drift, causing certain environmental pollution and waste, and long-term inhalation of these oil mists can easily cause respiratory diseases. To this end, we propose an aluminum foil lunch box forming system. Summary of the invention

[0003] The main purpose of the invention is to provide an aluminum foil lunch box forming system.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

There are two feed speed sensor modules, which correspond to the roller position. Two oil mist extractors are installed on the top of the protective cover. L-shaped through pipes are installed on the two oil mist extractors. An oil mist filter is installed between the two L-shaped through pipes. The two L-shaped through pipes and the oil mist filter are installed on the top of the protective cover. The oil mist filter is connected to the internal space of the protective cover through an extraction pipe. The two feed speed sensor modules transmit the aluminum foil travel speed data to the data processing module, and the data processing module controls the opening and closing of the oil nozzle and the oil mist extractor through the execution module.

[0006] A further improvement of the present invention is that a supporting cross plate is installed on the inner wall of the transmission channel, an electrically-controlled telescopic rod is installed on the supporting cross plate, the output end of the electrically-controlled telescopic rod is installed on the top of the protective cover, and two limit blocks are fixedly connected to the bottom end of the supporting cross plate, the limit blocks are in contact with the top of the protective cover, and the limit blocks are not in contact with the L-shaped through pipe.

[0007] A further improvement of the present invention is that a plurality of slide grooves are provided on the inner wall side of the transmission channel, a plurality of sliders are fixedly connected to the outer side of the protective cover, and the sliders are slidably connected to the corresponding inner walls of the slide grooves.

[0008] A further improvement of the present invention is that two card slots are provided at the bottom end of the protective cover, and two card plates are fixedly connected to the inner wall of the transmission channel. The card plates are inserted into the corresponding inner walls of the card slots, and the inner walls of the card slots are provided with sealing layers, and the card slots are in contact with the card plates through the sealing layers.

[0009] A further improvement of the present invention is that a scraper is installed on the side of the protective cover away from the stamping area, and a rubber sleeve is provided on the bottom end of the scraper. The scraper scrapes the top of the aluminum foil mother roll through the rubber sleeve.

[0010] A further improvement of the present invention is that a system for forming an aluminum foil lunch box comprises the following steps:

[0011] S1. The aluminum foil mother roll is unrolled and slid on the conveying channel. When the aluminum foil mother roll is between the protective cover and the conveying channel, it is sprayed with oil. The oil spray nozzle sprays oil on the aluminum foil mother roll, and the protective cover shields the excess oil mist. The oil mist extractor extracts and filters the oil mist in the protective cover through the L-shaped through pipe and the oil mist filter, so that the excess oil mist can be recovered, reducing the impact of oil mist leakage on the environment and respiratory health. After the oiling is completed, the aluminum foil mother roll arrives at the stamping area for stamping and forming.

[0012] S2. The aluminum foil mother roll can drive the yield gap to rotate, and the feed speed sensor module monitors the yield gap rotation, thereby realizing the control of the aluminum foil mother roll's travel speed. The feed speed sensor module transmits the aluminum foil mother roll's process data to the data processing module, and the data processing module issues instructions to the execution module. The execution module controls the oil spray nozzle to start oil spraying. At the same time, the execution module controls the oil mist extractor to start air circulation and filtration. According to the travel speed of the aluminum foil mother roll, the oil spray nozzle and the oil mist extractor start to operate at the appropriate power;

[0013] S3. Control the electric telescopic rod to shorten, and the electric telescopic rod drives the protective cover to slide upward, so that the protective cover can be raised, which is convenient for the initial arrangement of the aluminum foil mother roll and the maintenance of the internal components of the protective cover. When the protective cover is lowered, the card plate is inserted into the card slot, which increases the tightness between the protective cover and the transmission channel, so that the protective cover can block the internal oil mist and reduce the escape.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by placing the oil spray nozzle inside the protective cover to oil the aluminum foil mother roll, the protective cover blocks the excess and floating oil mist to prevent the oil mist from drifting to the external environment, thereby reducing pollution to the external environment and waste of oil, and reducing the impact of oil mist on respiratory health; the oil mist is drawn into the oil mist filter by the oil mist extractor for interception and filtration, so that the excess oil mist can be recovered, and the oil mist extractor, L-shaped through pipe and oil mist filter purify and circulate the gas in the oil spray nozzle to avoid the problem of external air entering and affecting the quality of oiling.

When the aluminum foil mother roll 2 slides below the stamping area 11, the stamping area 11 stamps the aluminum foil mother roll 2 in this area to realize the processing and forming of the aluminum foil lunch box. The protective cover 3 is in the space of the conveying channel 12, the protective cover 3 is on the route of the aluminum foil mother roll 2, and the protective cover 3 is in front of the stamping area 11.
