Metal mesh and mesh rack plastic-dipping heating furnace

Abstract

The invention belongs to the technical field of plastic-dipping heating furnaces, and particularly relates to a metal mesh and mesh rack plastic-dipping heating furnace. Aiming at the problem that heat transfer is not uniform and heat transfer through heat conduction is slow in an existing metal mesh and mesh rack heating process, and according to the following scheme, the plastic-dipping heatingfurnace comprises a furnace body, wherein a plurality of supporting legs are fixedly connected to the lower side wall of the furnace body, a rolling wheel is arranged at the lower end of each supporting leg, a material feeding hole is formed in the side wall of one side of the furnace body, a placing device and a plurality of heating wires are arranged between the inner walls of the two sides of the furnace body, a door plate matched with the material feeding hole is rotationally connected to the inner wall of the material feeding hole, and a convection mechanism is arranged on the lower sideof the furnace body. According to the metal mesh and mesh rack plastic-dipping heating furnace, the convection mechanism is arranged on the lower side of the furnace body, through the swinging of a gas outlet pipe and the leading-out of gas in the gas outlet pipe, the flow of the gas in the furnace body is accelerated, heat in the furnace body is uniformly distributed, the heat is directly transmitted out to heat a metal mesh, and the heating effect is better.

Description

technical field [0001] The invention relates to the technical field of plastic dipping heating furnaces, in particular to a plastic dipping heating furnace for metal mesh grids. Background technique [0002] As a filter or support, metal mesh is widely used in daily life. Metal mesh is generally made of different numbers of metal mesh and support mesh combined with edge wrapping process. [0003] After the metal mesh is produced, it needs to be dipped in plastic. Most of the liquid dipping process uses thermoplastic dipping liquid. The thermoplastic coating film has the characteristics of preheating and softening, and can be solidified to form a film after cooling. The main physical The process of permanent melt plasticization and film formation is relatively simple in processing and production. At present, the most typical and commonly used is polyvinyl chloride dipping solution, which is a synthetic raw material mixed with polyvinyl chloride with more than 10 kinds of adv...

AI Technical Summary

Problems solved by technology

[0005] 1. The heating wire is used for heating, and the heat dissipated from the heating wire cannot be quickly and evenly transferred to the upper and lower parts of the heating device; 2. The metal mesh is directly placed on the placement plate, and the heat transfer is relatively slow in the form of heat conduction

[0006] Therefore, the problems of uneven heat transfer and slow heat transfer of heat conduction when the metal mesh grid is heated need to be solved urgently.
