[0023] To solve the problem that simple thermal radiation heating has strong directionality and may cause uneven heating, please refer to Figure 1-5The utility model provides an embodiment: a plastic inner tray processing equipment for household appliance packaging, comprising a plastic sheet 1, and a heating chamber 6, the heating chamber 6 is located above the plastic sheet 1, a top plate 2 is arranged on the top of the heating chamber 6, a pressing plate 3 is arranged on the side of the heating chamber 6, a pressing block 301 is arranged below the pressing plate 3, the pressing plate 3 is connected to the top plate 2 through a telescopic rod 701, a hydraulic press 7 is arranged on the top of the top plate 2, a closed chamber 4 is arranged below the pressing plate 3, a heating coil 602, an air guide plate 603 and a heating tube 604 are arranged inside the heating chamber 6, a fan 601 is arranged on the side of the heating chamber 6, the heating coil 602 is oppositely installed on both sides of the air guide plate 603, the heating tube 604 is installed below the air guide plate 603, a mold 401 is arranged inside the closed chamber 4, a base 5 is arranged below the closed chamber 4, and a heating plate 402 is arranged between the mold 401 and the closed chamber 4.

[0024] The heating chamber 6 is divided into an upper part and a lower part, and the lower part of the heating chamber 6 is in an open state. A heating ring 602 and an air guide plate 603 are installed on the upper part of the heating chamber 6, and a heating tube 604 is installed on the lower part of the heating chamber 6. A fan 601 is installed on the side of the upper part of the heating chamber 6. The fan 601 blows natural wind from both sides to the inside of the heating chamber 6. The natural wind is first heated by the heating ring 602, and then guided to the lower part of the heating chamber 6 by the air guide plate 603. The natural wind is heated twice by the lower heating tube 604, and finally the fully heated natural wind is guided to the surface of the plastic sheet 1 by the lower part of the heating chamber 6, so that a certain area of ​​the plastic sheet 1 is evenly heated, so that a certain area of ​​the plastic sheet 1 is evenly softened, which is convenient for subsequent processing and further improves the processing quality of the plastic inner support.

[0025] Four guide pillars 201 and grooves 403 are arranged on the top of the closed chamber 4. The guide pillars 201 extend upward and pass through the pressure plate 3 and the top plate 2 in sequence. The inside of the closed chamber 4 is provided with a second air hole 404 and an air collecting chamber 405, and the air collecting chamber 405 is located below the second air hole 404; the surface of the mold 401 is provided with a first air hole 4012, and the inside of the mold 401 is provided with a cooling water channel 4011, and the cooling water channel 4011 extends outward with circulating water outlets respectively, and the circulating water outlets pass through the inside of the closed chamber 4 and the heating plate 402 and extend to the outside; the inside of the base 5 is provided with an air pump 501, and the air pump 501 is connected to the air collecting chamber 405 through a pipe 502.

[0026] The heating plate 402 heats the mold 401 to a certain temperature, which can reduce the temperature difference between the mold 401 and the plastic sheet 1, thereby reducing the internal stress and deformation problems of the plastic sheet 1 after molding; when the plastic sheet 1 needs to be separated from the surface of the mold 401, the temperature of the mold 401 is too high, which may easily cause the plastic sheet 1 and the mold 401 to stick together.
