Description

Technical Field

[0001] The utility model relates to the technical field of wax melting devices, in particular to a wax melting device for the production and processing of orthokeratology lenses. Background Technique

[0002] Orthokeratology lenses are worn on the surface of the eyeball to cause a shaping effect on the cornea, thereby reducing myopia. During the production process of these lenses, a wax melting device is required. In the prior art, a patent document with the publication number CN211216586U discloses a wax melting device for the production and processing of orthokeratology lenses, which includes a machine body and a heating box. A heating box is fixedly installed inside the machine body. A collecting spoon is arranged at the bottom end of the heating box, and a connecting rod is welded to the inner wall of the collecting spoon. Limiting rings are welded on the outer sides of the four groups of connecting rods, and the limiting rings are all sleeved on the surface of the bracket. The connecting rods are all welded inside the heating box. A connecting rod is welded in the middle of the collecting spoon, and a housing is welded on the outside of the heating box. Through the heat preservation layer and the cover plate, the heating box is sleeved to keep the heating box warm. When the heating box is not heating, the heat preservation layer and the cover plate keep the heating box warm, slowing down the solidification speed of the heating box and reducing the heating resources generated during heating. At the same time, by pulling the connecting rod, the connecting rod drives the collecting spoon to move, and the collecting spoon drives the limiting ring to move through the connecting rod, so that the limiting ring moves inside the bracket, facilitating the collection spoon to take the wax driven by the heating box and facilitating the taking of the wax.

[0003] Since most of the existing wax melting devices have a single melting groove structure, if too much wax material is placed, the heating and melting time is relatively long, and in many cases, not so much wax is needed. If too little is placed, it is inconvenient to take the material, which brings inconvenience to the use. Based on this, the existing wax melting devices have problems such as few melting grooves and difficulty in controlling the amount of wax material contained, and need to be further improved.

[0024] Among them, referring to Figure 3 , the transmission component includes a hexagonal column 10, the hexagonal column 10 is fixedly installed at the rotating end of the driving motor 2, a hexagonal groove 11 is opened on the lower surface of the rotating frame 3, and the hexagonal groove 11 can be slidably sleeved on the surface of the hexagonal column 10.

[0025] The transmission component further includes a first magnet 12 and a second magnet 13. The first magnet 12 is fixedly installed at the top of the hexagonal column 10, the second magnet 13 is fixedly installed in the hexagonal groove 11, and the first magnet 12 and the second magnet 13 can be magnetically adsorbed, so that the rotating frame 3 can be disassembled upward, as shown in Figure 4 or Figure 5 shown.

[0026] The heater includes a first housing 7, the first housing 7 is fixedly installed on the upper surface of the installation base 1, a heat-conducting metal plate 8 is embedded on the surface of the first housing 7, an electromagnetic heating coil 9 is fixedly installed inside the heat-conducting metal plate 8, the outer surface of the heat-conducting metal plate 8 is in an arc-shaped groove structure, the outer side surface of the melting material box 4 is in an arc-shaped structure, the outer surface of the melting material box 4 is in sliding contact with the inner wall of the arc-shaped groove of the heat-conducting metal plate 8, and the electromagnetic heating coil 9 is energized with high-frequency current to heat the heat-conducting metal plate 8, and the heat of the heat-conducting metal plate 8 is transmitted to the nearest melting material box 4.

[0027] In this embodiment, a second outer shell 14 is fixedly installed on the upper surface of the installation base 1. The second outer shell 14 is in a ring structure. The rotating frame 3 is rotatably arranged inside the inner ring of the second outer shell 14, and the outer side surface of the melting material box 4 is in sliding contact with the inner ring surface of the second outer shell 14.

[0028] A heat preservation cavity 15 is opened inside the second outer shell 14. An input pipe 16 and an output pipe 17 are respectively fixedly installed on the surface of the second outer shell 14, and both the input pipe 16 and the output pipe 17 are communicated with the heat preservation cavity 15.

[0029] Inside the heat preservation cavity 15, a plurality of partition plates 18 are fixedly installed. An overflow gap 19 is reserved on the upper side of the partition plate 18. The cooling medium is input through the input pipe 16. The cooling medium flows into the heat preservation cavity 15, overflows through each overflow gap 19, fills the heat preservation cavity 15, and finally is discharged from the output pipe 17, as Figure 2 shown by the dashed line.

[0030] A transparent protective cover 20 is hingedly installed on the upper surface of the first housing 7. The transparent protective cover 20 covers the upper side of the second outer shell 14.

[0031] By providing the second outer shell 14, the heat preservation cavity 15 inside the second outer shell 14 is separated into a plurality of chambers by the partition plate 18.

It is also possible to heat and raise the temperature of a certain material melting box 4 according to needs. In special cases, it is not necessary to repeatedly raise the temperature of all the wax materials, so that the heater can interrupt work, and its heat energy can be fully utilized, reducing energy consumption, thereby achieving the effect of convenient heating and material taking.

[0033] Working principle: Place the wax material in each material melting box 4. The heater conducts heat to the material melting box 4, so that the material melting box 4 close to the heater is heated to promote the melting of the wax material. Then, drive the motor 2 to drive the rotating frame 3 to rotate at a fixed angle, so that the other material melting boxes 4 are respectively rotated to the heat conducting metal plate 8 of the heater for separate heating. As the rotating frame 3 rotates, the material melting box 4 far from the heater is cooled by the cooling medium in the heat preservation cavity 15 and slowly cools down, so that the temperatures of the wax material liquids in different material melting boxes 4 are also different. The temperature of the wax material liquid in each material melting box 4 can be observed from the temperature display screen 6. Wax materials in a suitable temperature range can be selected to wax the orthokeratology lens. It should be noted that a small amount of wax material can also be placed in a certain material melting box 4 for separate heating and melting. After use, the rotating frame 3 and the material melting box 4 can be taken out together for cleaning.
