Hot-pressing shaping heating plate for paper pulp molding production equipment, manufacturing method of hot-pressing shaping heating plate and paper pulp molding production equipment

Abstract

The invention discloses a hot-pressing shaping heating plate for paper pulp molding production equipment. A heat conduction channel extending along the plane direction of the heating plate is integrally formed in the heating plate, and comprises a channel extension section, a channel inlet and a channel outlet; the channel extension section is connected with the channel inlet and the channel outlet, the channel inlet and the channel outlet are formed in the side face of the heating plate, and a heat conduction medium is introduced into the heat conduction channel. The invention further discloses paper pulp molding production equipment comprising the hot-pressing shaping heating plate. The hot-pressing shaping heating plate for the paper pulp molding production equipment is high in corrosion resistance and long in service life; the heat exchange area is increased, that is, the heating power of the heating plate is increased, the thermal compensation time is greatly shortened, and the production efficiency is improved; the leakage problem of the heating plate is avoided; the surface strength of the heating plate is improved, and the contact fitting degree of the mold and the heatingplate after long-time use is solved.

Description

technical field [0001] The invention relates to the technical field of heating devices, in particular to a hot-pressing and setting heating plate for pulp molding production equipment, a manufacturing method thereof, and pulp molding production equipment including the heating plate. Background technique [0002] The existing degradable products produced by pulp molding that meet environmental protection requirements are mainly food packaging such as cups, bowls, plates, plates, etc., industrial packaging such as mobile phone holders, notebook computer shockproof holders, razors, etc., agricultural packaging such as seedling trays , flower trays, etc., medical packaging such as disposable urinals, spittoon trays, endoscopic trays, etc. [0003] The principle of heat transfer and heat radiation is used to heat the product mold. The conventional heating methods include: electric heating plate, steam or heat transfer oil heating plate, such as plugging in electric heating tubes,...

AI Technical Summary

Problems solved by technology

[0008] (3) If the casting is not good, the possibility of oil leakage may be left, causing the hidden danger of scalding people

[0009] (4) Taking the heating plate size of 950×700mm as an example, the heat exchange area of ​​the pre-embedded elbow with a diameter of 20mm is only 0.67m 2 , reducing the heat exchange rate and extending the temperature rise compensation time
