Description

Technical Field

[0001] The utility model belongs to the technical field of curing ovens and relates to curing oven equipment for blue light protection eyeglass lenses. Background Art

[0002] Anti-blue light glasses are a type of glasses that can prevent blue light from irritating the eyes. Special anti-blue light glasses can effectively isolate ultraviolet rays and radiation and filter blue light. They are suitable for use when watching computers or TV, and can play a good role in protecting the eyes. The principle of anti-blue light glasses to isolate blue light lies in the fit of the film and the resin lens. In order to ensure the perfect combination of the film and the lens, a curing oven is required for curing operation.

[0003] Patent publication number CN215511912U discloses a curing furnace for improving the transmittance of resin lenses, including a furnace body, heating tubes and a WiFi module. This solution uses heating tubes, temperature controllers, insulation tubes and microprocessors to use multiple heating tubes for separate heating to ensure consistent temperature inside the furnace and avoid excessive temperature differences, thereby improving the temperature control accuracy of the curing furnace. The placement plate and air blowing fan can evenly dissipate the heat inside the furnace body, ensuring that the curing state of resin lenses at different positions is consistent, thereby improving the curing quality of the resin lenses.

[0004] The above-mentioned curing oven has the following disadvantages when in use: a large number of lenses are put into the oven for curing, and the space between the uppermost interlayer and the lowermost end is large, resulting in a large overall device volume. Although multiple heating tubes are controlled separately, it is inevitable that heat cannot fully contact the lenses, especially the edges of the lenses. For this reason, we have designed a curing oven device for blue light blocking lenses. Summary of the Invention

[0009] In the curing furnace device for the anti-blue light spectacle lens, a purification carbon column is arranged in the waste gas treatment cylinder, and a tail sealing plate is arranged at one end of the purification carbon column and corresponds to the connecting section of the spherical exhaust head. The purpose of the arrangement is to further treat the waste gas, reduce the pollution to the air in the workshop, and improve the convenience of operation when the purification carbon column is taken out and cleaned together with the separation of the spherical exhaust head.

[0010] In the curing furnace device for the anti-blue light spectacle lens, the length of the purification carbon column is equal to the length of the waste gas treatment cylinder in combination with the thickness of the tail sealing plate, and the air port of the purification carbon column corresponds to the tail port of the exhaust pipeline. The purpose of the arrangement is to make the purification carbon column have good purification effect, and make the waste gas entering through the exhaust pipeline enter the purification carbon column completely, so as to avoid the waste gas being mixed in the gap between the waste gas treatment cylinder and the purification carbon column.

[0022] Embodiment 1: A cylinder support 11 is installed on the inner side of the curing furnace body 1, and a rotating cylinder 9 is installed at the center of the cylinder support 11 by bolts. A circular rotating seat 10 is installed at the rotating axis of the rotating cylinder 9. A plurality of annularly distributed lens mold holders 12 are arranged on the top of the circular rotating seat 10, and a lens mold 13 is installed on the top of the plurality of lens mold holders 12. A plurality of annularly distributed vertical rods 14 are arranged on the top of the cylinder support 11, and a UV lamp mounting seat 15 is arranged at one end of the plurality of vertical rods 14, which is connected to the outer ring of the circular rotating seat 10 but does not affect the rotation of the circular rotating seat 10. A plurality of annularly distributed UV lamp mounting rods 16 are arranged on the top of the UV lamp mounting seat 15, and a plurality of UV curing lamps 17 are respectively mounted on the rod head of the UV lamp mounting rod 16 and the irradiation end of the UV curing lamp 17 corresponds to the lens mold 13.

[0023] The advantages of this embodiment are: the circular rotating seat 10 is driven to rotate by the rotating cylinder 9 so that the lens mold 13 rotates together, so that the edge of the lens can be fully cured, thereby improving the comprehensiveness of the curing, making the overall structure compact, reducing the height of the overall equipment, and facilitating and efficient transportation.

[0024] Embodiment 2: A grille-type air collecting hood 18 is set, and the grille-type air collecting hood 18 is located at the top of the inner cavity of the curing furnace body 1 and corresponds to the circular rotating seat 10. An exhaust pipe 6 is set at the top of the grille-type air collecting hood 18, and the exhaust pipe 6 passes through the sealed air duct of the curing furnace body 1 and is connected to the exhaust gas treatment tube 7. A spherical exhaust head 8 with activated carbon filling is set at one end of the exhaust gas treatment tube 7; a purification carbon column 19 is installed inside the exhaust gas treatment tube 7, and a tail sealing plate 20 is set at one end of the purification carbon column 19, and the tail sealing plate 20 corresponds to the connecting section of the spherical exhaust head 8; this scheme can guide the exhaust gas generated during the curing process to the interior of the exhaust gas treatment tube 7, use the purification carbon column 19 for preliminary treatment, and discharge the exhaust gas through the spherical exhaust head 8 with activated carbon filling, which can achieve good optimization effect and reduce the pollution of the workshop environment by the exhaust gas.

[0025] Among them, in the length design of the purification carbon column 19, the length of the purification carbon column 19 combined with the thickness of the tail sealing plate 20 is equal to the length of the exhaust gas treatment tube 7, and the air port of the purification carbon column 19 corresponds to the tail port of the exhaust pipe 6.

[0026] In Example 1, in order to better control multiple UV curing lamps 17 through the touch screen control computer 21 and reduce the impact of multiple UV curing lamps 17 on the circuit, the touch screen control computer 21 is located on one side of the curing furnace body 1 and the lamp interface of the touch screen control computer 21 is connected to the main wire connector 22, one end of the main wire connector 22 is connected to the assembly wiring 23, and branch wiring 24 is set at the wiring sockets of multiple UV curing lamps 17, and each branch wiring 24 is connected to the assembly wiring 23 through an electrical terminal.

[0027] Furthermore, since the UV lamp mounting base 15 does not rotate, the assembly wiring 23 is set at the edge of the UV lamp mounting base 15 through a wire clip, thereby improving the wiring effect inside the curing furnace body 1.

[0028] Among them, the touch screen control computer 21 is internally integrated with a PLC control system (which is existing technology and will not be repeated here), which can effectively electrically control multiple UV curing lamps 17. It also needs to be connected to the rotating cylinder 9 to achieve effective control of the rotation rate.

[0029] In the scheme of embodiment 1, the lens mold holder 12 is distributed in a ring-shaped manner, wherein, when the diameter of the circular rotating seat 10 is 100, the number of the lens mold holder 12 is set to 6, and the number of the UV curing lamps 17 is also set to 6. When the diameter of the circular rotating seat 10 is expanded to 150, the number of the lens mold holder 12 can be set to 8 or 9, which is improved according to the actual size of the circular rotating seat 10 but is affected by the external dimensions of the curing furnace body 1.

[0030] In the scheme of Example 2, during the curing process of the UV curing lamp 17, the temperature inside the curing furnace body 1 increases, and the temperature inside the exhaust gas treatment tube 7 is low, resulting in a temperature-pressure difference, causing the internal gas (mixed with exhaust gas) to enter into the exhaust pipe 6. The exhaust pipe 6 is set to a one-way pipe structure to avoid the backflow of exhaust gas inside the exhaust pipe 6 after power failure.
