Problems solved by technology

Among them, for PP plastics, the Vicat softening temperature is 150°C. However, due to the low efficiency of heat application in existing electric heating furnaces, the general electric heating block temperature needs to reach 180-240°C to quickly soften PP, and higher Temperature means more energy is expended

Abstract

The invention relates to the field of thermoplastic forming, in particular to a double-layer heating furnace based on the low-temperature long-distance race principle. The double-layer heating furnace comprises heating rods, heating plates, a feeding belt, a face overturning device and a furnace body. Each heating rod comprises a heating body and walking wheels, wherein a heating unit is arranged in the heating body, and the walking wheels are arranged at the two ends of the heating body. The face overturning device comprises a driving drive plate, a sheave, a cross shaft, a buckle, a spiral rod, a motor and a supporting plate with strip-shaped through holes. The cross shaft penetrates the through holes in the corresponding positions on the two sides. The sheave is fixed to the cross shaft. The driving drive plate is arranged above the sheave. One end of the spiral rod is connected with an output shaft of the motor. The cross shaft is clamped through one end of the buckle, and the other end of the buckle is arranged outside the spiral rod in a sleeving manner. According to the double-layer heating furnace, the low-temperature long-distance race design thought is adopted, the length of the heating plates is increased, plastic plates can be preheated in advance, and the plastic plates can be softened at the low temperature; and the overturning design is adopted for the top heating rods, top heat accumulation is avoided, and the heat utilization efficiency is higher.

Description

technical field [0001] The invention relates to the field of thermoplastic molding, in particular to a double-layer heating furnace based on the principle of low-temperature long-distance running. Background technique [0002] The electric heating furnace is an important component of the thermoplastic molding machine. The thermoplastic molding machine is a machine that absorbs heated and plasticized thermoplastic coils such as PVC, PE, PP, PET, HIPS, etc. into various shapes of advanced packaging and decoration boxes, frames and other products. The thermoplastic molding machine mainly uses the vacuum suction generated by the vacuum pump to heat and soften PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic plastic sheets into various shapes of vacuum covers and blisters through molds. Trays, blisters, etc. Among them, for PP plastics, the Vicat softening temperature is 150°C. However, due to the low efficiency of heat application in existing electric heating furnaces,...
