Detailed Implementation

[0036] The following description provides many different embodiments or examples for implementing various features of the present invention. The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This embodiment provides a feeding device for an optical glass bath furnace, such as... Figure 1 As shown, it includes:

[0039] The feeding mechanism 10 is used to feed materials into the optical glass bath furnace;

[0040] A feeding drive mechanism 20 is used to drive the feeding mechanism 10 to move closer to the optical glass furnace and away from the optical glass furnace.

[0041] The material picking drive mechanism 30 is used to drive the feeding drive mechanism 20 and the feeding mechanism 10 to reciprocate between the material picking position and the feeding position.

[0042] In some embodiments, such as Figure 4 As shown, the feeding mechanism 10 includes a scoop 11, a receiving connecting rod 12, and a support structure 14. The lower end of the support structure 14 is fixedly connected to the feeding drive mechanism 20. One end of the receiving connecting rod 12 is rotatably connected to the support structure 14, and the other end is connected to the scoop 11.

[0043] For example, such as Figure 4As shown, the scoop 11 is tightly fitted with the receiving scoop connecting rod 12 via an mounting sleeve and is fixed by a locking screw.

[0044] For example, such as Figure 5 As shown, the receiving connecting rod 12 is connected to the rotary motor 17 via the gear 18. The rotary motor 17 drives the gear 18 to rotate, thereby causing the receiving connecting rod 12 to rotate.

[0045] In some embodiments, the scoop 11 is provided with a hollow cavity for injecting coolant. This cools the scoop 11.

[0046] It should be noted that the present invention does not limit the location of the hollow cavity. The hollow cavity can be on the side wall of the scoop 11, or at the bottom of the scoop 11, or both the side wall and the bottom can be hollow cavities.

[0047] In some embodiments, such as Figure 4 As shown, the hollow cavity is connected to an inlet pipe 15 and an outlet pipe 16. The inlet pipe 15 and outlet pipe 16 facilitate control of the coolant's flow within the hollow cavity. Preferably, as... Figure 4 As shown, the water inlet of the hollow cavity is located below the water outlet of the hollow cavity.

[0048] For example, such as Figure 1 The supporting structure 14 is a control box. One end of the receiving connecting rod 12 is located inside the control box, and the other end passes through the control box and is located outside the control box. The end is connected to a rotary joint 13. The rotary motor 17 and the gear 18 are located inside the control box.

[0049] It should be noted that the rotary joint 13 is an existing product and can be purchased and used directly; the rotary joint 13 has an inner ring and an inner bearing structure; the water pipe is connected to the rotary joint 13 to supply water to the water inlet pipe 15; by setting the rotary joint 13, water pipe tangling can be avoided. Figure 4 As shown, the outlet of the water inlet pipe 15 is connected to the hollow cavity, and the inlet of the water inlet pipe 15 is connected to one end of a channel (not shown in the figure) located inside the receiving connecting rod 12. The other end of the channel is connected to the rotary joint 13.

[0050] In some embodiments, the water inlet pipe 15 includes a first water inlet pipe and a second water inlet pipe, which are connected by a quick-connect coupling. The water outlet pipe 16 includes a first water outlet pipe and a second water outlet pipe, which are connected by a quick-connect coupling. After scale builds up inside the water inlet pipe 15 and / or the water outlet pipe 16, it can be cleaned by removing the quick-connect coupling.

[0051] In some embodiments, such as Figure 6 As shown, the feeding drive mechanism 20 includes a trolley frame 21, a first guide rail 22, a movable platform 23, and a drive reduction motor 24. The lower end of the trolley frame 21 is connected to the material picking drive mechanism 30, and the upper end of the trolley frame 21 is connected to two symmetrically arranged first guide rails 22. The movable platform 23 is slidably connected to the first guide rails 22. The upper end of the movable platform 23 is connected to the lower end of the support structure 14, and the drive reduction motor 24 drives the movable platform 23 to move.

[0052] The trolley frame 21 is constructed from a rectangular tube welded profile frame.

[0053] Working principle: Drive the geared motor 24 to move the moving platform 23 so that the scoop 11 can quickly enter the furnace. The scoop 11 rotates and puts the material in the scoop 11 into the furnace. Drive the geared motor 24 to move the moving platform 23 so that the scoop 11 can exit the furnace and the furnace door is closed.

[0054] Because the cantilever of the receiving connecting rod 12 is too long, with the rear end supported by a bearing and the front scoop 11 being relatively heavy, especially after feeding, the scoop is suspended for a long time, which can easily cause deformation of the receiving scoop connecting rod 12. Therefore, in some embodiments, such as Figure 2 As shown, the trolley frame 21 is also provided with a support mechanism 40 for supporting the scoop 11.

[0055] For example, such as Figure 2 As shown, the support mechanism 40 includes a top plate 41 and a lifting cylinder. A support steel plate is provided above the trolley frame 21, and the lifting cylinder is connected to the support steel plate. The extension rod of the lifting cylinder is connected to the top plate 41, and the top plate 41 is used to support the scoop 11. When the scoop 11 is not rotating, the lifting cylinder extends and lifts, so that the top plate 41 supports the scoop 11; when the scoop 11 rotates, the lifting cylinder retracts and disengages from the support.

[0056] In some embodiments, such as Figure 2 As shown, a protective cover 50 is provided above the trolley frame 21 at one end near the optical glass furnace.

[0057] In some embodiments, such as Figure 2 As shown, the support structure 14 is positioned above the protective cover 50.

[0058] In this embodiment, the feeding device is used with the optical glass furnace at the front, where the ambient temperature is high. Especially when the furnace door is open, heat is transferred from inside the furnace and directly radiates to the feeding device, easily causing component failure. Therefore, in some embodiments, such as... Figure 3As shown, a radiation shield 60 is provided at one end of the trolley frame 21 near the optical glass furnace. The radiation shield 60 can be made of aluminum silicate fiberboard, which effectively provides heat insulation.

[0059] In some embodiments, such as Figure 7 , Figure 8 As shown, the material handling drive mechanism 30 includes a second guide rail 31 (not shown in the figure), a platform frame 32, and a drive shaft 33, a chain 34, a drive motor 35, and a pulley 36 disposed on the platform frame 32. The drive motor 35 is connected to the drive shaft 33 through the chain 34. The drive shaft 33 is fixed to the bottom surface of the platform frame 32 by bearings. The drive shaft 33 is fixedly connected to the pulley 36, and the pulley 36 is slidably connected to the second guide rail 31.

[0060] like Figure 9 As shown, for example, two second guide rails 31 are provided, and correspondingly, pulleys 36 are provided at both ends of the drive shaft 33. Providing two guide rails makes the movement of the material handling drive mechanism 30 smoother and has the advantage of improved safety.

[0061] For example, such as Figures 7-9 As shown, a movable cable chain 37 is also provided, which is used to hold the cable and protects the cable during the movement of the material handling drive mechanism 30. Figure 9 A connecting plate is provided between the two second guide rails 31, and a guide groove is provided on the connecting plate. The guide groove is used to guide the moving cable chain 37.

[0062] For example, such as Figure 7 , Figure 8 As shown, a sensor electrical box is provided on the top surface of the platform frame. By setting sensors at corresponding positions of the feeding mechanism 10, feeding drive mechanism 20, and material picking drive mechanism 30 in this utility model, precise automated control of the feeding mechanism 10, feeding drive mechanism 20, and material picking drive mechanism 30 can be achieved.

[0063] like Figures 1-2 As shown, the top surface of the platform frame 32 is provided with a lifting adjustment seat 70. The lifting adjustment seat 70 can be used to adjust the height of the feeding mechanism 10, making it more applicable and also improving safety.
