The heating system of the existing plastic spraying curing furnace generally adopts a rotor type heating pipe, a plurality of groups of rotor type heating pipes are suspended and fixed on the inner wall of a furnace body, after the heating system is electrified, the rotor type heating pipes generate heat to heat the air in the inner cavity of the furnace to 180-200 ℃, and the powder coating on the surface layer of a workpiece in the furnace body is baked at high temperature. Meanwhile, a temperature sensor is generally arranged at the upper part of the inner side wall of the furnace body, when the temperature in the furnace reaches a set temperature (200 ℃), the rotor type heating pipe is powered off, heating is stopped, and when the temperature is lower than the set temperature (180 ℃), the rotor type heating pipe is powered on to continue heating.
The heating system of the plastic spraying curing oven has the following disadvantages: the heat energy generated by the rotary wing type heating pipe during working mainly radiates the area near the rotary wing type heating pipe, the inner cavity of the plastic spraying curing furnace for processing the large-size workpiece is inevitably large, the plastic spraying curing furnace is heated by the rotary wing type heating pipe only in a radiation mode, air in the plastic spraying curing furnace is heated unevenly, the heat efficiency is low, the distance between the temperature sensor and the rotary wing type heating pipe is large, when the temperature detected by the temperature sensor reaches 200 ℃, the temperature of the area near the rotary wing type heating pipe exceeds 200 ℃, the workpiece position in the area can be burnt, and defective products are produced. Therefore, the heating system of the plastic injection curing oven is in need of improvement.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a heating system of spraying plastics curing oven to solve foretell technical problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a heating system of a plastic spraying curing oven comprises a plurality of groups of rotary wing type heating pipes, an electric cabinet and a temperature sensor, wherein the electric cabinet and the temperature sensor respectively correspondingly control the rotary wing type heating pipes; the method is characterized in that: the hot air circulation fan is characterized by also comprising at least two air distribution pipelines, an air supply pipeline and a hot air circulation fan; the rotary wing type heating pipe is flatly paved at the bottom of a furnace chamber of the plastic spraying curing furnace, and a protection plate covers the rotary wing type heating pipe; the air distribution pipeline is positioned below the rotary wing type heating pipe, one end of the air distribution pipeline is closed, the other end of the air distribution pipeline is communicated with the air supply pipeline, and air blowing holes are uniformly formed in the top surface of the air distribution pipeline along the length direction of the air distribution pipeline; the hot air circulating fan is positioned outside the body of the plastic spraying curing furnace, the air inlet of the hot air circulating fan is communicated with the furnace chamber of the plastic spraying curing furnace, and the air outlet of the hot air circulating fan is communicated with the air supply pipeline.
Preferably, gaps are reserved between the rotor type heating pipe and the protection plate and between the rotor type heating pipe and the air distribution pipeline.
Has the advantages that: compared with the prior art, the utility model discloses with rotor formula heating pipe tiled in the furnace chamber bottom of spraying plastics curing oven, and set up the cloth wind pipeline that can blow upwards in the below of rotor formula heating pipe, utilize the air circulation flow in the heated air circulation fan makes the spraying plastics curing oven, the heat energy that the cloth wind pipeline generated rotor formula heating pipe generates heat passes through the air convection, it is quick, radiate whole furnace chamber evenly, not only can improve the thermal efficiency greatly, the air that also enables the furnace chamber is heated evenly, the temperature error that temperature sensor detected is little, can avoid the local phenomenon of baking paste of work piece, guarantee product quality.
