Abstract

A special furnace for solidification of resin lenses is composed of a steam exhaust pipe (1), an upper exhaust fan (2), a back exhaust fan (3), heating wires (4), a furnace body (5), a lens material rack (6), rollers (7), a furnace door (8) and a hot air exhaust pipe (9). The heating wires (4) are installed on the periphery of an inner cavity of the furnace body (5). The steam exhaust pipe (1) is arranged on the upper exhaust fan (2) which is arranged on the top of the furnace body (5). The lens material rack (6) is arranged on the rollers (7) which are installed on the furnace body (5). The special furnace is characterized in that the hot air exhaust pipe (9) is arranged on the back exhaust fan (3), and the back exhaust fan (3) is arranged on the back of the furnace body (5). By means of the special furnace, resin steam can be exhausted out of the furnace body in real time according to the concentration of the resin steam in the furnace, and hot air in the furnace body can be automatically exhausted out before the furnace door is opened.

Description

A kind of resin lens solidification special furnace

Technical field

The present invention relates to a kind of stove, being particularly suitable for the special furnace that resin lens uses when solidifying.

Background technology

What present ophthalmic lens used is resin lens mostly.Resin lens is in a liquid state state before producing shaped.When producing, resin liquid being injected mould, with viscose glue, mould mouth being sealed after mould is filled with resin liquid, then putting into curing oven and be heating and curing.Curing oven was simple heat treatment when heat treatment in the past, and the steam that eyeglass evaporates when heat treatment then cannot process.

Summary of the invention

For above deficiency, the object of the present invention is to provide a kind of resin lens solidification special furnace, be adopt electrical heating, outwards bled by air draft pipe in heating process, by temperature-dropping fan, the hot gas in stove is extracted out after heat treatment is good.While heating, can also according to the concentration of resin vapor in stove, and in blow-on in front of the door, can be real-time extract resin vapor out body of heater.

Technical scheme of the present invention is achieved in the following ways: a kind of resin lens solidification special furnace, be made up of steam exhaust pipe, upper exhaust fan, back of the body exhaust fan, heater strip, body of heater, eyeglass material frame, roller, fire door, hot gas discharge pipe, described heater strip is arranged on around body of heater inner chamber, vapour-discharge tube is arranged on exhaust fan, exhaust fan is arranged on body of heater top, eyeglass material frame is arranged on roller, roller is arranged on body of heater, it is characterized in that: described hot gas discharge pipe is arranged on back of the body exhaust fan, and back of the body exhaust fan is arranged on the back side of body of heater.

Described eyeglass material frame is provided with lens mold, and heat the lens mold of body of heater inner chamber after heater strip energising, the resin vapor in body of heater is extracted out outside body of heater by hot gas discharge pipe by upper exhaust fan.

The present invention, the eyeglass material frame of full lens mold will be installed, pushed in body of heater by roller and close upper furnace door, heating wire starts to heat in body of heater, in heating process, liquid resin evaporates steam after heating, after vapour concentration to finite concentration being detected in body of heater, upper exhaust fan is started working and to be extracted out by steam exhaust pipe by the steam in body of heater, start working to back exhaust fan in the heat time, hot gas in body of heater is discharged by hot gas discharge pipe, after the hot gas of body of heater is drawn out of, fire door can be opened, prevent from being scalded by the hot gas in body of heater when opening fire door.

Accompanying drawing explanation

Fig. 1 is main schematic diagram of the present invention;

Schematic diagram when Fig. 2 is work of the present invention;

Fig. 3 is side of the present invention schematic diagram.

Known by Fig. 1, Fig. 2, Fig. 3, a kind of resin lens solidification special furnace, is made up of steam exhaust pipe 1, upper exhaust fan 2, back of the body exhaust fan 3, heater strip 4, body of heater 5, eyeglass material frame 6, roller 7, fire door 8, hot gas discharge pipe 9.Described heater strip 4 is arranged in body of heater 5, and vapour-discharge tube 1 is arranged on exhaust fan 2, and exhaust fan 2 is arranged on body of heater 5 top, eyeglass material frame 6 is arranged on roller 7, roller 7 is arranged on body of heater 5, and hot gas discharge pipe 9 is arranged on back of the body exhaust fan 3, and back of the body exhaust fan 3 is arranged on body of heater 5 back side.

Described heater strip 4 heats body of heater 5 after powered up, upper exhaust fan 2 extracts the resin vapor in body of heater 5 out body of heater 5, eyeglass material frame 6 is for installing lens mold, and roller 7 facilitates eyeglass material frame 6 in use, and hot gas is extracted out in body of heater 5 by hot gas discharge pipe 9 by back of the body exhaust fan 3.
