It has the characteristics of light weight, high optical performance, no antigenicity, inflammatory, carcinogenicity and biodegradability.

[0003] China Publication No.: CN212041237U discloses a paraffin dripping device for an artificial lens blank, including a workbench, a positioning cavity for holding the blank and a hopper for collecting paraffin are respectively provided on both sides of the top of the workbench, a first positioning platform and a second positioning platform for clamping the blank are respectively provided on both sides of the interior of the positioning cavity, wherein the second positioning platform is elastically installed inside the positioning cavity, a discharge pipe for controlling the discharge flow of paraffin is provided through one side of the exterior of the hopper, and a wax dripping nozzle is provided at the bottom end of the discharge pipe. The utility model is provided with an outer leakage ring and an inner leakage ring structure in the discharge pipe, and the flow of paraffin can be controlled by rotating the inner leakage ring, so as to achieve precise wax dripping and avoid the waste of paraffin materials.

[0026] In combination with the above structure, when the clamping assembly 2 is in use, a pull plate 14 is pulled, so that the corresponding moving rod 13 pulls the L-shaped clamp 15 away from the center of the device, and the crystal blank is placed on the placement groove 1501 of the other L-shaped clamp 15, and the pull plate 14 is slowly released. Under the reset action of the reset spring 16, the corresponding L-shaped clamp 15 moves toward the other L-shaped clamp 15, so that the crystal blank is located in a pair of placement grooves 1501, thereby fixing the position of the crystal blank.

[0027] Combined with Figure 3 A collecting groove 101 is provided at the center of the front upper end of the base 1 to collect excess paraffin. A plug cover 102 is provided at the front end of the collecting groove 101. The lower end opening of the conical discharge head 8 corresponds to the center of the collecting groove 101, that is, corresponds to the fixed position of the crystal blank, which is convenient for paraffin dripping.

[0028] Embodiment 2

[0029] Based on the first embodiment, combined with the attached Figure 2 The adjusting assembly 10 includes an adjusting rod 17 that passes through the end of the horizontal conveying pipe 7 and is slidably connected thereto, a pull plate 18 and a push plate 19 are fixed to the inner and outer sides of the adjusting rod 17 respectively, and a sealing ring 20 is provided at the end of the horizontal conveying pipe 7 through which the adjusting rod 17 passes and is slidably connected.

At this time, the upper opening of the conical discharge head 8 is fully opened, and the adjustment rod 17 drives the push plate 19 to move by pushing and pressing the pull plate 18, so that the push plate 19 pushes the piston 9 to move, thereby making the upper opening of the conical discharge head 8 smaller, thereby reducing the flow rate of paraffin.

[0031] Combined with Figure 2 The adjusting component 11 includes an adjusting rod 21 fixed on the end of the piston 9 away from the push plate 19, the end of the adjusting rod 21 passes through the side wall of the tank 4 and is fixed with a push plate 22, and the side wall of the tank 4 is provided with a sealing ring 23 through which the adjusting rod 21 passes and is slidably connected.

[0032] In combination with the above structure, when the adjustment component 11 is used, by pushing the push plate 22, the adjustment rod 21 drives the piston 9 to move toward the end direction in the horizontal conveying pipe 7, so that the opening at the upper end of the conical discharge head 8 becomes larger, thereby increasing the flow rate of paraffin; when the device is finished using, by pulling the push plate 22, the adjustment rod 21 pulls the piston 9 in the horizontal conveying pipe 7 toward the material tank 4, and pushes the paraffin in the horizontal conveying pipe 7 into the material tank 4, preventing the paraffin from solidifying and causing blockage of the horizontal conveying pipe 7, affecting the next use.

[0033] The specific usage is as follows:

[0034] The crystal blank is clamped by the clamping component 2, and the solid paraffin is placed in the material tank 4 and heated and melted by the heating plate 5. At this time, the piston 9 is located at the starting end in the horizontal conveying pipe 7. The push plate 22 is pushed by the adjusting component 11, so that the adjusting rod 21 drives the piston 9 to move toward the end direction in the horizontal conveying pipe 7, so that the opening at the upper end of the conical discharge head 8 becomes larger, thereby increasing the flow rate of the paraffin, and the paraffin is discharged through the conical discharge head 8 and falls onto the crystal blank; the push plate 2 18 is pushed by the adjusting component 10, so that the adjusting rod 17 drives the push plate 19 to move, so that the push plate 19 pushes the piston 9 to move, so that the opening at the upper end of the conical discharge head 8 becomes smaller, thereby reducing the flow rate of the paraffin, thereby realizing the control of the paraffin flow rate and preventing the waste of paraffin; after the paraffin liquid drips on the crystal blank, the operator manually covers the special chuck on the crystal blank, and after the paraffin solidifies, the two are fixed;

[0035] When the device is finished using, the push plate 22 in the adjusting component 2 11 is pulled, so that the adjusting rod 21 pulls the piston 9 to move in the horizontal conveying pipe 7 toward the material tank 4, pushing the paraffin in the horizontal conveying pipe 7 into the material tank 4 to prevent the paraffin from solidifying and causing the horizontal conveying pipe 7 to be blocked, affecting the next use.

[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
