The technical field is as follows:
the invention relates to the field of glass hot bending, in particular to a glass microwave hot bending furnace.
Background art:
the traditional glass hot bending technology uses a resistance furnace to heat the glass in the furnace integrally, is slow in time and low in heating efficiency, cannot selectively heat a specific area, and may have certain influence on the performance of other areas of the glass. The microwave heating technology has the advantages of high heating rate, low power consumption and selective heating. However, the existing microwave hot bending furnace has the problems of complex structure, inconvenience in use, single process, low hot bending efficiency and the like.
The invention content is as follows:
the utility model provides a curved stove of glass microwave heat, it includes the cavity, is equipped with the feed inlet other end at cavity one end and is equipped with the discharge gate, its characterized in that: a group of microwave generators are arranged in the cavity, a glass roller way is arranged in the cavity, a carrier roller is arranged in the cavity on one side of the glass roller way, and a heating resistance wire and a thermocouple are also arranged in the cavity.
On the basis of the technical scheme, the following further technical scheme can be provided:
the carrier roller is made of microwave absorbing materials such as graphite or silicon carbide.
An infrared thermometer is also arranged in the cavity at one side of the carrier roller.
The glass roller way is made of microwave non-absorption materials such as stainless steel, ceramics, glass and the like.
And a cavity on one side of the carrier roller is fixedly connected with a supporting plate which inclines downwards, and one end of the supporting plate is tangent to the roller surface of the carrier roller.
The invention has the advantages that:
the invention has simple structure and convenient use, adopts a microwave heating mode, has high heating rate and small range, thereby improving the hot bending efficiency and saving the heating energy consumption. In addition, the arrangement of the heating resistance wires can keep the temperature in the oven cavity at a certain temperature in advance, so that the glass is prevented from being broken due to too fast heating rate under microwave heating or too fast cooling when the microwave is turned off.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention.
The specific implementation mode is as follows:
as shown in figure 1, the glass microwave hot bending furnace comprises a cavity 1 of the hot bending furnace, wherein a feeding hole 6 is formed in one end of the cavity 1, and a discharging hole 7 is formed in the other end of the cavity 1. The cavity 1 is internally provided with a glass roller way 5 which is horizontally distributed, and rollers which form the glass roller way 5 are made of stainless steel which does not absorb microwaves.
The supporting roller 4 made of graphite is fixedly connected in the cavity 1 on one side of the glass roller way 5, and the axes of the supporting roller 4 and the glass roller way 5 are on the same horizontal plane and have the same diameter, so that the glass 12 placed on the glass roller way 5 and the supporting roller 4 can be horizontally distributed.
A group of microwave generators 2 are fixedly connected in the cavities 1 at the upper side and the lower side of the carrier roller 4 and the glass roller way 5, and a heating resistance wire 9 is also fixedly connected in the cavity 1 above the glass roller way 5. A thermocouple 10 is fixedly connected in the cavity 1 above the carrier roller 4. An infrared thermometer 8 which is distributed oppositely to the carrier roller 4 is fixedly connected in the cavity 1 below the carrier roller 4.
A supporting plate 11 which inclines downwards is fixedly connected in the cavity between the carrier roller 4 and the discharge hole 7, and the supporting plate 11 is made of stainless steel which does not absorb microwave. One end of the supporting plate 11 is tangent to the roller surface of the supporting roller 4, and the end part of the other end of the supporting plate is provided with a flanging 11a vertical to the supporting plate 11.
The working process is as follows:
firstly, turning on an electric heater 9, raising the temperature in the furnace body 1 to the annealing temperature suitable for the glass 12 to be processed, preserving the heat, and monitoring the temperature in the furnace body 1 through a thermocouple 10;
secondly, opening a feeding hole 6, putting glass 12 to be processed into the furnace body 1 from the feeding hole 6 by a mechanical arm of an industrial robot not shown in the figure, placing most of the glass in a glass roller way 5, calibrating the position until the position of the glass 12 to be thermally bent is placed at a supporting roller 4, withdrawing the mechanical arm of the industrial robot from the furnace body 1, and then closing the feeding hole 6;
thirdly, the microwave generator 2 is started through the control console, and the carrier roller 4 is heated by the microwaves because the carrier roller 4 is made of graphite;
fourthly, monitoring the temperature of the carrier roller 4 through an infrared thermometer 8, and after the temperature of the female die 4 reaches the softening temperature suitable for the glass to be processed, adjusting the microwave power through a control console to keep the temperature stable so as to maintain the softening degree of a hot bending area;
fifthly, waiting for the glass 12 at the position of the roller 4 to be thermally bent under the action of gravity until the glass is attached to the mold 11, and then closing the microwave generator 2; the turned edge 11a can play a role in blocking the glass, and the hot bend of the glass is prevented from being stretched under the action of gravity.
Sixthly, continuously annealing, finishing the hot bending operation of the glass 12 after the annealing is finished, opening a mechanical arm of the industrial robot at the discharge port 7, extending into the furnace body 1, and taking out the glass 12 from the discharge port 7;
and seventhly, repeating the second step to the sixth step, and continuing the production flow.
