Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a device for producing hyperboloid glass. Background Technology

[0002] In the field of curved glass manufacturing, especially in the production of hyperboloid glass, traditional processing methods mainly rely on hot bending forming. This process typically involves extruding heated and softened flat glass using upper and lower molds, followed by cooling to set the shape. However, existing technologies still face the following bottlenecks in practical applications: traditional roller conveyor mechanisms are mostly continuous designs, and the high-temperature softened glass is prone to sliding or shifting due to inertia during transport, leading to inaccurate positioning. Uneven stress on the glass edges during mold closing can cause cracks or thickness deviations. Furthermore, the glass may stick to the upper and lower molds, making it difficult to demold and affecting the equipment's normal processing efficiency. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figure 1-8 An apparatus for manufacturing hyperboloid glass includes a frame 1, an intermittent roller conveyor mechanism 2 located on the lower inner side of the frame 1, a first lifting mechanism 3 located on the top of the frame 1, an upper mold 4 located at the lifting end of the first lifting mechanism 3, the first lifting mechanism 3 being used to control the height of the upper mold 4, a second lifting mechanism 5 located on the top of the frame 1, the second lifting mechanism 5 being used to control the height of the intermittent roller conveyor mechanism 2, and a conveying trolley mechanism 6 located on the inner side of the frame 1, with a lower mold 7 located on the conveying trolley mechanism 6.

[0034] The frame 1 serves as the carrier for the aforementioned components and is constructed from standard profiles welded together. The intermittent roller conveyor mechanism 2 transports the heated glass between the upper mold 4 and the lower mold 7. The second lifting mechanism 5 lowers the intermittent roller conveyor mechanism 2, causing the glass to detach from it and fall onto the lower mold 7. Then, driven by the first lifting mechanism 3, the upper mold 4 descends and contacts the glass. Under the pressure of the upper mold 4 and the lower mold 7, the glass forms the desired curved surface. After rapid cooling, the glass retains its processed curved surface, completing the production of the curved glass. Different shapes of curved glass can be produced by changing the molds. The second lifting mechanism 5 enables the overall lifting of the intermittent roller conveyor mechanism 2.

[0035] The lower mold 7 is mounted on the conveyor trolley mechanism 6. After the glass is formed, the conveyor trolley mechanism 6 transfers the lower mold 7 along with the formed glass to the next workstation. Optionally, the conveyor trolley mechanism 6 and the equipment at the next workstation are either corresponding to each other or interconnected.

[0036] Specifically, the intermittent roller conveyor mechanism 2 is used for conveying heated glass. The intermittent roller conveyor mechanism 2 includes a first motor reducer 203, which drives a first sprocket 2031 to rotate. The first sprocket 2031 drives a transition shaft 2032 via a chain. The transition shaft 2032 is mounted on a support 2012, and the transition shaft 2032 drives the rotating roller assembly 201 to convey the glass via a chain. The conveying speed of the rotating roller assembly 201 can be adjusted by a computer.

[0037] The roller assembly 201 consists of rollers 2011 wound with high-temperature resistant aramid rope. The roller assemblies 201 are arranged intermittently, and the rollers 2011 are fixedly mounted on the base 2013 via supports 2012. Each roller assembly 201 serves as a quickly replaceable roller unit. The distance between the roller assemblies 201 can be adjusted arbitrarily according to usage requirements without affecting the transmission of rotational power. To ensure smooth chain drive, a chain guide rail is added to the base 2013. A positioning rod 202 is provided on the base 2013 for limiting the movement of the glass during transport.

[0038] Specifically, the first lifting mechanism 3 includes an electric servo cylinder 301. The lifting end of the electric servo cylinder 301 drives the lifting frame 302 to move up and down, thereby controlling the mold to move up and down, and finally realizing the extrusion molding of glass by the upper mold 4 and the lower mold 7. The guide optical shaft 303 and the linear bearing 101 are guide components. The linear bearing 101 is located on the top of the frame 1 and corresponds to and cooperates with the guide optical shaft 303 to ensure the stability of the electric servo cylinder 301 driving the lifting frame 302 to move up and down. The bottom of the guide optical shaft 303 is provided with a mold mounting frame 305, and the bottom of the mold mounting frame 305 is fixedly installed with the upper mold 4.

[0039] Specifically, the second lifting mechanism 5 includes a second motor reducer 501, which drives a second sprocket 502 to rotate via a transmission shaft 503. A chain is mounted on the second sprocket 502. A third sprocket 504 is mounted on the base 2013 of the intermittent roller conveyor mechanism 2. The second sprocket 502 is connected to the third sprocket 504 via the chain. When the second motor reducer 501 drives the second sprocket 502 to rotate clockwise, the intermittent roller conveyor mechanism 2 is lifted; when the second sprocket 502 rotates counterclockwise, the intermittent roller conveyor mechanism 2 is lowered. A lifting guide mechanism 506 is used to limit the movement of the intermittent roller conveyor mechanism 2. The lifting guide mechanism 506 is located on the inner bottom of the frame 1 and is movably connected to the base 2013 of the intermittent roller conveyor mechanism 2. The lifting guide mechanism 506 ensures smooth up-and-down movement of the intermittent roller conveyor mechanism 2.

[0040] The conveyor mechanism 6 is used to transport the formed hyperboloid glass to the next processing station, such as the cooling station. The conveyor mechanism 6 includes a third motor reducer, which is mounted on a linear guide rail 505. The third motor reducer drives the lower mold frame to move horizontally along the linear guide rail 505 via a sprocket and a chain. The sprocket and chain are located inside the linear guide rail 505. The lower mold frame is partially connected to the chain. After the third motor reducer is started, the sprocket rotates and drives the chain to move. The lower mold frame and the lower mold 7 follow the chain and move horizontally along the linear guide rail 505. The third motor reducer operates in both forward and reverse directions to control the lower mold frame to move closer to or away from the frame 1. The linear guide rail 505 is connected to the frame 1.

[0041] The lower mold frame is used to install and fix the lower mold 7. The lower mold 7 can be removed from the lower mold frame and replaced to fit different shapes of the upper mold 4.

[0042] Based on the above solution, the automation level and production efficiency of existing technologies are improved to a certain extent. Secondly, the replaceable upper mold 4 and lower mold 7 can enrich the variety of glass products and meet market demands. In addition, the overall structure of this solution is compact and simple, occupies less space, and the spacing between the rollers conveying the glass can be adjusted arbitrarily. It can be flexibly arranged according to the size of the equipment and the size of the glass, improving the flexibility of equipment use.

[0043] Example 2 Please see Figure 1-13 As shown, based on the above embodiments, the above solution is improved. Specifically, a horizontal push rod 8 is provided at the bottom of the lower mold 7. The telescopic end of the horizontal push rod 8 is connected to the vertical push rod 9 through the mounting platform 801. An air suction head 901 is provided at the top of the vertical push rod 9. An expansion cover 902 is provided at the top of the air suction head 901. The expansion cover 902 is located in the middle of the lower mold 7 under the drive of the horizontal push rod 8. An air suction pipe is connected to the air suction head 901.

[0044] The bottom of the lower mold 7 is also provided with a telescopic plate 701. The inner side of the extension end of the telescopic plate 701 is provided with a support rod 702. The telescopic plate 701 is fixedly connected to the suction head 901 through the support rod 702. The mounting platform 801 is provided with a limiting slide plate 804 on the side near the longitudinal push rod 9. The longitudinal push rod 9 is provided with a support plate 805. The support plate 805 is slidably connected to the limiting slide plate 804. The mounting platform 801 is provided with a connecting seat 802 on one side. The connecting seat 802 is provided with an electric push rod 803. The telescopic end of the electric push rod 803 is fixedly connected to the support plate 805. Under the sliding cooperation of the support plate 805 and the limiting slide plate 804, the electric push rod 803 pushes the support plate 805, the longitudinal push rod 9 and the suction head 901 to move horizontally along the limiting slide plate 804.

[0045] In operation, the lower mold 7 is moved by the conveyor trolley mechanism 6 to the intermittent roller conveyor mechanism 2, which then transfers the glass onto the lower mold 7. At this point, the horizontal height of the intermittent roller conveyor mechanism 2 is higher than the upper surface of the lower mold 7. When the intermittent roller conveyor mechanism 2 has transported the glass past the top side of the lower mold 7, it immediately stops and is de-energized. The intermittent roller conveyor mechanism 2 then pauses transport, and the electric push rod 803 extends, causing the longitudinal push rod 9 and the suction head 901 to be positioned below the glass. Then, by lifting the longitudinal push rod 9, the expansion cover 902 is brought into contact with the lower surface of the glass, and the suction head 901 is activated. The negative pressure drawn downward by the suction head 901 is used to improve the stability of the connection with the glass. Then, dragging one end of the glass, the electric push rod 803 retracts a preset distance, so that the glass is pulled and moved by the support and negative pressure of the expansion cover 902 and is positioned directly above the lower mold 7. Then, the downward airflow drawn by the suction head 901 is stopped, and the longitudinal push rod 9 retracts and resets, so that the glass is directly aligned with the lower mold 7.

[0046] Subsequently, the intermittent roller conveyor 2 moves downward, while the conveying trolley mechanism 6 continues to drive the lower mold 7 to move to the position corresponding to the upper mold 4. As the first lifting mechanism 3 drives the upper mold 4 to press down the glass and connect with the lower mold 7, the glass is processed into shape.

[0047] Furthermore, the suction head 901 can not only draw air downwards through the suction pipe, but also supply air in the reverse direction through the suction pipe to blow air upwards. After the upper mold 4 and the lower mold 7 have formed the glass, the upper mold 4 moves upwards a short distance under the drive of the first lifting mechanism 3. At this time, the operator observes whether the glass is lifted upwards by the upper mold 4. If the glass is lifted upwards, the suction head 901 is restarted. Using the negative pressure drawn downwards by the suction head 901, a downward suction force is provided for the glass connection. During this process, the vertical push rod 9 drives the suction head 901 and the expansion cover 902 to move up and down. At the same time, the extension and retraction of the electric push rod 803 controls the horizontal position of the suction head 901 and the expansion cover 902. For example, during the continuous downward suction process of the suction head 901 and the expansion cover 902, the electric push rod 803 drives the suction head 901 and the expansion cover 902 to stop and suction on both sides of the bottom of the glass to accelerate the separation speed of the glass from the upper mold 4.

[0048] In addition, the above method is not only used for the separation of glass from the upper mold 4, but also during the demolding stage of glass from the lower mold 7. By switching the airflow direction of the suction head 901 and the expansion cover 902 from downward suction to upward blowing, and similarly, the electric push rod 803 drives the suction head 901 and the expansion cover 902 to stop on both sides of the bottom of the glass, respectively, to push upward airflow, so as to assist the glass in detaching from the lower mold 7 when it sticks to the lower mold 7. By controlling the retraction of the transverse push rod 8, interference between the mounting platform 801, the longitudinal push rod 9, and the telescopic plate 701 and the internal components of the frame 1 can be avoided.
