Description

Technical Field

[0001] This utility model relates to the field of optical glass processing technology, specifically a mechanism for automatically pushing raw materials in optical glass processing. Background Technology

[0002] Optical glass is an amorphous (glassy) optical medium that transmits light. It can be used to make various optical elements such as prisms, lenses, and filters, altering the direction, phase, and intensity of light after it passes through. Based on different requirements, optical glass can be divided into three main categories: ① Colorless optical glass – almost completely transparent across a wide visible and near-infrared wavelength range, it is the most widely used type of optical glass. There are hundreds of grades based on refractive index and dispersion, which can be divided into two types: crown glass (represented by K) and flint glass (represented by F). Crown glass is borosilicate glass; adding alumina creates flint glass. The main difference is that flint glass has a higher refractive index and dispersion, making it more commonly used in spectral elements. ② Radiation-resistant optical glass – possessing all the properties of colorless optical glass and exhibiting minimal performance changes under radioactive irradiation. Used in optical instruments exposed to gamma radiation, its types and grades are the same as colorless optical glass. Its chemical composition is based on colorless optical glass, with the addition of a small amount of cerium dioxide to eliminate color centers formed by high-energy radiation in the glass, making the light absorption of this glass change very little after irradiation. ③ Colored optical glass—has specific absorption or transmission properties for certain wavelengths of light. Also known as filter glass, there are over a hundred varieties. Color filters selectively absorb certain colors, while neutral density filters absorb all wavelengths of light equally, only reducing the intensity of the beam without changing its color. Interference filters, based on the principle of light interference, reflect unwanted colors instead of absorbing them. Optical glass has high transparency, high chemical and physical (structural and performance) homogeneity, and specific and precise optical constants. It can be divided into silicate, borate, phosphate, fluoride, and chalcogenide series.

[0003] The raw materials for optical glass need to be fused in a heating furnace before being placed into a mold for shaping. During this process, the raw materials, which are in a high-temperature molten state, need to be transferred from the heating furnace to the mold. This process is not convenient to operate. If the waiting time is too long, the temperature will drop, affecting the molten state and causing the formed optical glass to fail to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to overcome the problems mentioned in the background art and provide a mechanism for automatically pushing raw materials in optical glass processing. This mechanism pushes the heated raw materials out of the heating furnace and flips them into the material trough, while pushing away the material holding container, thereby shortening the waiting time and improving efficiency.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A mechanism for automatically pushing raw materials in optical glass processing includes a support platform. A heating furnace is fixed to the top of the support platform. One end of the heating furnace has an opening and a through slot, which are connected. A horizontal moving mechanism is provided on the side wall of the heating furnace. The horizontal moving mechanism is connected to the heating furnace and can move horizontally relative to it. A rotating mechanism is provided above the horizontal moving mechanism. The rotating mechanism and the horizontal moving mechanism are inserted into the through slot and can move horizontally with the horizontal moving mechanism and rotate around their own axis. A pushing mechanism is fixed to the side wall of the heating furnace. The pushing mechanism can move horizontally and is located above the rotating mechanism. Currently, transferring raw materials in a high-temperature molten state from the heating furnace to the mold is often done manually. This is inefficient, time-consuming, and involves continuous high-temperature work, which is also risky. Furthermore, excessive waiting time for the raw materials can cause the temperature to drop, affecting the molten state and resulting in the finished optical glass failing to meet requirements. To address the aforementioned issues, this solution proposes a mechanism for automatically pushing raw materials during optical glass processing. The mechanism includes a support platform, which serves as the support for the entire system. A heating furnace is fixed to the top of the support platform. The heating furnace has openings at both ends, and its internal structure utilizes a circulating chain for conveying raw materials. This is a conventional component. Raw materials are conveyed into the high-temperature heating furnace via this component and output from the outlet end. The outlet end of the heating furnace has an opening and a through-slot, which are connected. A horizontal moving mechanism is installed on the side wall of the heating furnace. This horizontal moving mechanism is connected to the heating furnace and can move horizontally relative to it. The horizontal moving mechanism can perform horizontal reciprocating motion, entering the heating furnace to collect and transport raw materials. Its rapid action reduces the cooling time of the raw materials and also ensures that the raw materials are heated as much as possible. The furnace maintains a high temperature. A rotating mechanism is installed above the horizontal moving mechanism. The rotating mechanism and the horizontal moving mechanism are inserted into the through slot and can move horizontally with the horizontal moving mechanism and rotate around their own axis. The rotating mechanism and the horizontal moving mechanism work together. When the heated raw material is taken out of the heating furnace by the horizontal moving mechanism and placed in a suitable position, the rotating mechanism flips the raw material into the material trough and into the mold for forming. A pushing mechanism is fixed to the side wall of the heating furnace. The pushing mechanism can move horizontally and is located above the rotating mechanism. The pushing mechanism pushes the container for pouring out the raw material out of the opening to the collection point, and then the next set of raw materials is taken out and pushed out. Through this cyclical operation, mechanized operation is achieved, the waiting time is shortened, the efficiency is improved, and the safety risks are reduced.

[0007] Furthermore, the horizontal moving mechanism includes a support plate and a horizontal power mechanism, both of which are fixed to the side wall of the heating furnace. A support plate is installed above the support plate, and the support plate is connected to both the horizontal power mechanism and the support plate. Under the action of the horizontal power mechanism, the support plate can slide horizontally on the support plate. The support plate serves as the load-bearing component of the horizontal moving mechanism. The support plate is fixed, while the support plate moves horizontally under the action of the horizontal power mechanism. The horizontal power mechanism is generally a cylinder, which connects a piston rod to the support plate. The extension and retraction of the piston rod within the cylinder drives the support plate to move, resulting in rapid and accurate action.

[0008] Furthermore, to ensure more accurate movement of the pallet and define its trajectory, a guide rail is installed on the top of the support plate, and a guide block is fixed to the bottom of the pallet. The bottom of the guide block is concave to form a guide groove, and the guide rail is inserted into the corresponding guide groove, allowing the pallet to move along the guide rail. Through the cooperation of the guide groove and the guide rail, the pallet always moves in a straight line.

[0009] Furthermore, the rotating mechanism includes a mounting bracket fixed to the top surface of the support plate. A motor is mounted on one end of the mounting bracket, and a mounting shaft is provided at the other end. The mounting shaft is connected to the motor and can rotate with it. A guide frame is provided on the side wall of the heating furnace away from the support plate, and a guide groove is provided in the guide frame. The mounting shaft passes through the through groove and is inserted into the guide groove. A bearing is fitted onto the end of the mounting shaft located in the guide groove, with the outer ring of the bearing located in the guide groove. This ensures that the rotation of the mounting shaft is not affected, and its horizontal movement is limited by the guide groove, while also preventing it from wobbling.

[0010] Furthermore, a feeding plate is fitted onto the outer wall of the mounting shaft. The feeding plate is located at the opening of the heating furnace and can enter the furnace as the mounting shaft moves, and it can also rotate with the mounting shaft. The feeding plate has several parallel insertion rods, each equipped with a barb. By inserting the feeding plate into the furnace, it can reach the bottom of the material-holding mold. By tilting it upwards at a small angle, the material-holding mold can be removed from the furnace surface and moved backwards. It is then caught by the barbs and moved to a suitable position. The feeding plate rotates a certain angle with the mounting shaft, pouring the heated raw material into a material trough, which guides it into the corresponding mold for shaping. Due to the barbs, the material-holding mold does not move with the raw material.

[0011] Furthermore, the pushing mechanism includes a connecting plate, which is fixed to the side wall of the heating furnace. A pushing cylinder is fixed to the connecting plate, and a piston rod in the pushing cylinder can move horizontally along the cylinder. A pushing disc is fixed to the end of the piston rod outside the pushing cylinder, and the pushing disc is located above the material feeding plate. After the material feeding mold has finished unloading, it needs to be moved to prevent it from affecting the next operation. Therefore, the piston rod's extension and retraction movement in the cylinder pushes the unloaded material feeding mold out of the opening to the collection point. Then, the piston rod returns to its original position to prevent obstructing the movement of the material feeding plate. The piston rod pushes the material feeding mold horizontally, without being restricted by barbs.

[0012] In summary, this utility model has the following advantages compared with the prior art: This solution utilizes a rotating mechanism and a horizontal moving mechanism in combination. When the heated raw material is taken out of the heating furnace by the horizontal moving mechanism to a suitable position, the rotating mechanism flips the raw material into the material trough and enters the mold for forming. Then, the pushing mechanism pushes the material container that pours out the raw material out of the opening to the collection point. Then, the next set of raw materials is taken out and pushed out. Through this cyclical operation, mechanized operation is achieved, the waiting time is shortened, the efficiency is improved, and the safety risks are reduced. Attached Figure Description

[0020] like Figure 1 As shown in this embodiment, a mechanism for automatically pushing raw materials in optical glass processing includes a support platform 1 and a heating furnace 17 mounted on top of the support platform 1. The heating furnace 17 is an existing component, and its internal heating and conveying of raw materials is achieved through a circulating chain. Because high-temperature heating is required, the conveying speed is very slow. An opening 16 and a through groove 15 are provided at one end of the heating furnace 17, and the through groove 15 and the opening 16 are connected. The through groove 15 is a recessed channel from the opening, which facilitates the removal of raw materials from the heating furnace 17 during operation.

[0021] A horizontal moving mechanism is provided on the side wall of the heating furnace 17. This mechanism is connected to the heating furnace 17 and can move horizontally relative to it. The horizontal moving mechanism is capable of horizontal reciprocating motion, allowing it to enter the heating furnace 17 for raw material removal and conveying. Its rapid action reduces the cooling time of the raw materials and also helps maintain their high temperature within the heating furnace 17. The horizontal moving mechanism includes a support plate 3 and a horizontal power mechanism, both fixed to the side wall of the heating furnace 17. To increase stability, multiple ribs 2 are fixed to the side wall of the heating furnace 17, with the tops of the ribs 2 and the bottoms of the support plate 3 fixed. A support plate 6 is provided above the support plate 3, connected to both the horizontal power mechanism and the support plate 3. Under the action of the horizontal power mechanism, the support plate 6 can slide horizontally on the support plate 3. With the support plate 3 stationary, the support plate 6 moves horizontally under the action of the horizontal power mechanism. The horizontal power mechanism is preferably a cylinder, connecting a piston rod to the support plate 6. The extension and retraction of the piston rod within the cylinder moves the support plate 6, resulting in rapid and accurate movement. To ensure more accurate movement of the pallet 6 and limit its trajectory, a guide rail 5 is installed on the top of the support plate 3, and a guide block 4 is fixed to the bottom of the pallet 6. The bottom of the guide block 4 is recessed to form a guide groove, and the guide rail 5 is inserted into the corresponding guide groove, allowing the pallet 6 to move along the guide rail 5. Through the cooperation of the guide groove and the guide rail 5, the pallet 6 always moves in a straight line.

[0022] A rotating mechanism is provided above the horizontal moving mechanism. Both the rotating and horizontal moving mechanisms are inserted into the through slot 15 and can move horizontally with the horizontal moving mechanism and rotate around their own axis. The rotating mechanism includes a mounting frame 8, which is fixed to the top surface of the support plate 6. A motor 7 is mounted on one end of the mounting frame 8, and a mounting shaft 14 is provided on the other end. The mounting shaft 14 is connected to the motor 7 and can rotate with the motor 7. A guide frame is provided on the side wall of the heating furnace 17 away from the support plate 3. A guide groove is provided in the guide frame. The mounting shaft 14 passes through the through slot and is inserted into the guide groove. A bearing is fitted at one end of the mounting shaft 14 located in the guide groove, with the outer ring of the bearing located in the guide groove. This ensures that the rotation of the mounting shaft 14 is not affected, and its horizontal movement is limited by the guide groove, while also preventing it from wobbling. The mounting shaft 14 is driven to rotate by the motor 7, and the horizontal movement of the mounting shaft 14 and the motor 7 is driven by the support plate 6. A feeding plate 13 is fitted onto the outer wall of the mounting shaft 14. The feeding plate 13 is located at the opening of the heating furnace 17 and can enter the interior of the heating furnace 17 as the mounting shaft 14 moves, and can also rotate with the mounting shaft 14. When the feeding plate 13 moves, it inserts into the interior of the heating furnace 17 and can insert into the bottom of the material holding mold. The material holding mold is removed from the plate of the heating furnace and moved to a suitable position. The feeding plate 13 rotates a certain angle with the mounting shaft, pouring the heated raw material into the material trough, which guides it into the corresponding mold for forming.

[0023] A pushing mechanism is fixed to the side wall of the heating furnace 17. The pushing mechanism is capable of horizontal movement and is located above the rotating mechanism. The pushing mechanism includes a connecting plate 10, which is fixed to the side wall of the heating furnace 17. A pushing cylinder 9 is fixed to the connecting plate 10. The piston rod 11 in the pushing cylinder 9 is capable of horizontal movement along the pushing cylinder 9. A pushing plate 12 is fixed to one end of the piston rod 11 outside the pushing cylinder 9, and the pushing plate 12 is located above the unloading plate 13. After the material is unloaded, the filling mold needs to be moved to prevent it from affecting the next operation. Therefore, the piston rod is pushed out of the opening to the collection point by the extension and retraction movement of the cylinder. Then the piston rod returns to its original position to prevent it from blocking the movement of the unloading plate 13.

[0024] This solution utilizes a rotating mechanism, a horizontal moving mechanism, and a pushing mechanism. When the heated raw material is taken out of the heating furnace 17 by the horizontally moving feeding plate 13, it is moved horizontally to the opening. The rotating mechanism flips the raw material into the material trough, making it easier to enter the mold for forming. The pushing mechanism pushes the material container that pours out the raw material horizontally out of the opening to the collection point. Then, the next set of raw materials is taken out and pushed out. Through this cyclical operation, mechanized operation is achieved, the waiting time is shortened, the efficiency is improved, and the safety risks are reduced.
