Description

Technical Field

[0001] This invention relates to the field of glass technology, specifically to a stepped glass and its preparation method. Background Technology

[0002] As people's living standards gradually improve and their aesthetic concepts continue to evolve, a large number of complex, technologically advanced, and aesthetically pleasing glass products have appeared in people's lives and are widely used. Stepped glass is a common type of glass product used for building curtain walls or for decoration. In the existing technology, common production methods for stepped glass include mold production and grinding. However, both of these common methods have certain drawbacks: when producing stepped glass using molds, it is necessary to customize a mold according to the size of the stepped glass, and then put the molten glass raw material into the forming mold. After the molten glass cools, the stepped glass of the corresponding size can be obtained. However, this method can only produce stepped glass of fixed sizes, with low adaptability and high mold manufacturing costs. In the existing technology of producing stepped glass by grinding, there are generally requirements for the shape of the glass raw material, which requires cutting glass raw materials that do not conform to the shape, and then grinding the cut finished products. This setup increases the production process of stepped glass. Based on this, this application proposes a stepped glass and its preparation method. Summary of the Invention

[0014] The method for preparing the stepped glass includes the following steps:

[0015] Step 1: The staff places the raw material for the stepped glass production that needs to be polished onto the vacuum suction cup;

[0016] Step 2: The hydraulic rod 2 retracts, causing the sealing cylinder, which is fixedly connected to it, to move downwards. During the downward movement of the sealing cylinder, the sealing column moves downwards until the distance between the top of the sealing cylinder and the top of the hollow disk is the same as the distance between the bottom of the grinding wheel 2 and the top of the worktable. At this point, the top of the sealing column separates from the top of the hollow disk. The vacuum pump is started, and the raw material for producing stepped glass is connected to the vacuum suction cup under negative pressure.

[0018] Step 4: Grinding Structure 1, Grinding Structure 2, and Grinding Structure 3 operate sequentially. In Grinding Structure 1, the rotating motor 1 drives the grinding wheel 1 to rotate. Under the action of the hydraulic rod 3, the grinding wheel 1 contacts the raw material for stepped glass production. After the raw material is ground into a stepped shape, the grinding wheel 1 returns to its original position. In Grinding Structure 2, the grinding wheel 2 grinds the lower part of the stepped glass. After the lower part of the stepped glass is ground to form the upper and lower edges, the grinding wheel 2 returns to its original position.

After the upper edge 2 is ground to form the upper edge, the grinding wheel 3 returns to its original position. This completes the production of the stepped glass.

[0019] Step 5: The power structure stops working, and the turntable stops rotating; hydraulic rod one retracts, and during the retraction of hydraulic rod one, hydraulic rod two extends, so that the top of the hollow disc is flush with the top of the turntable while the position of the sealing cylinder remains unchanged. The vacuum pump stops working, and the staff removes the prepared stepped glass.

[0020] Preferably, the outer diameter of the hollow disc is not greater than the bottom diameter of the stepped glass, and the outer diameter of the sealing cylinder is the same as the outer diameter of the intermediate part of the stepped glass.

[0021] Preferably, the vacuum pump is fixedly connected to the bottom of the sealing cylinder, and the end of the vacuum tube away from the vacuum pump inlet extends into the inner cavity of the hollow disc.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1-2 As shown, the present invention provides a stepped glass, including a stepped glass body, which includes a lower stepped glass 1 and an upper stepped glass 2 made from a piece of glass of any shape. The upper outer ring of the top of the lower stepped glass 1 is provided with an upper edge 4, and the lower outer ring of the bottom of the lower stepped glass 1 is provided with a lower edge 5. Both the upper edge 4 and the lower edge 5 are annular. The height and taper of the upper edge 4 and the lower edge 5 are the same.

Under the action of the upper edge 3, the top diameter of the upper part 2 of the stepped glass is smaller than the bottom diameter.

[0039] like Figure 3-5 As shown, the aforementioned stepped glass requires a stepped glass preparation machine during preparation. This machine includes a worktable 6, a power structure, and a dust removal structure. A turntable 7 is movably connected inside the inner cavity of the worktable 6. The power structure can drive the turntable 7 to rotate. In some embodiments of this application, the power structure includes a rotary motor 12, a gear 13, and a gear ring 11. The rotary motor 12 is fixedly connected to the worktable 6. The output shaft of the rotary motor 12 is fixedly connected to the gear 13 via a reducer. The gear ring 11 is fixedly connected to the outer ring of the turntable 7. The gear 13 and the gear ring 11 are in a meshing state. When the rotary motor 12 rotates, the rotation of the rotary motor 12 can drive the gear 13 fixedly connected to it to rotate. The gear 13 drives the turntable 7 to rotate through the meshing gear ring 11.

[0040] like Figure 6-7 As shown, the top center of the inner cavity of the turntable 7 is provided with a placement groove adapted to the material for making stepped glass. A vacuum suction cup is movably connected inside the placement groove. The vacuum suction cup has a split structure, which includes a hollow disc 8 and a sealing cylinder 9. The hollow disc 8 is located inside the inner cavity of the sealing cylinder 9, and sealing columns 10 are uniformly fixedly connected to the bottom of the inner cavity of the sealing cylinder 9. The top and bottom of the inner cavity of the hollow disc 8 are provided with suction holes adapted to the sealing columns 10. The sealing columns 10 are located inside the suction holes. When the bottom of the hollow disc 8 contacts the bottom of the inner cavity of the sealing cylinder 9, the top of the sealing column 10, the top of the hollow disc 8, and the top of the sealing cylinder 9 are flush.

[0041] like Figure 8 As shown, a hydraulic rod 14 is fixed at the bottom of the hollow disk 8. The other end of the hydraulic rod 14 is fixedly connected to the bottom of the inner cavity of the turntable 7. By setting the hydraulic rod 14, the extension and retraction of the hydraulic rod 14 can change the height of the hollow disk 8.

[0042] A hydraulic rod 2 15 is fixedly connected to the bottom of the sealing cylinder 9. The other end of the hydraulic rod 2 15 is fixedly connected to the bottom end of the hydraulic rod 1 14. By setting the hydraulic rod 2 15, the extension and retraction of the hydraulic rod 2 15 can change the distance between the sealing cylinder 9 and the hollow disc 8. When the top of the sealing cylinder 9 is flush with the top of the hollow disc 8, the hydraulic rod 2 15 is in an extended state.

[0043] A vacuum pump 16 is fixed to the bottom of the sealing cylinder 9. A vacuum tube is fixed to the air inlet end of the vacuum pump 16. The vacuum tube is retractable. In some embodiments of this application, the vacuum tube is a corrugated tube. The other end of the vacuum tube extends into the inner cavity of the hollow disk 8. When the vacuum pump 16 is working, it can remove the air from the hollow disk 8.

[0044] Furthermore, the outer diameter of the hollow disc 8 is not greater than the bottom diameter of the lower part 1 of the stepped glass, and the outer diameter of the sealing cylinder 9 is the same as the outer diameter of the middle part of the lower part 1 of the stepped glass.

[0045] As described above, the retraction of hydraulic rod 14 can cause the vacuum suction cup to move downward, and the extension of hydraulic rod 14 can cause the hollow disc 8 to move upward.

[0046] The outer ring at the top of the workbench 6 has three grinding structures: grinding structure one, grinding structure two, and grinding structure three. Grinding structure one can be used to grind the raw material for the production of stepped glass—circular glass—into a stepped shape. Grinding structure two can be used to grind the lower part of the intermediate product of the stepped shape, so that the lower part of the stepped glass is ground into upper edge 4 and lower edge 5. Grinding structure three can be used to grind the upper part of the intermediate product of the stepped shape, so that the upper part of the stepped glass is ground into upper edge 3. The combined use of grinding structures one, two, and three can realize the production of stepped glass.

[0047] The aforementioned polishing structure includes a hydraulic rod 28, which is embedded in the worktable 6. A support plate 21 is fixed to the other end of the hydraulic rod 28. The support plate 21 is L-shaped, with its other end positioned above the worktable 6. A rotary motor 23 is fixed to the top of the other end of the support plate 21, and a polishing wheel 22 is movably connected to the bottom of the other end of the support plate 21. The output shaft of the rotary motor 23 is fixedly connected to the middle part of the top of the polishing wheel 22. The distance between the polishing wheel 22 and the vacuum suction cup can be changed using the hydraulic rod 28, and the rotary motor 23 can drive the polishing wheel 22 to rotate, allowing it to polish the raw material when it comes into contact with it. Furthermore, to simplify the polishing process, the thickness of the polishing wheel 22 in this application is the same as the height of the upper part 2 of the stepped glass.

[0048] The second grinding structure includes a hydraulic rod four embedded in the worktable 6. The other end of the hydraulic rod four is fixedly connected to a support plate two 19. The other end of the support plate two 19 is located above the worktable 6. A rotating motor two is fixedly attached to the top of the other end of the support plate two 19. A grinding wheel two 20 is movably connected to the bottom of the other end of the support plate two 19. The end of the output shaft of the rotating motor two is fixedly connected to the middle part of the top of the grinding wheel two 20. The distance between the grinding wheel two 20 and the vacuum suction cup can be changed by using the hydraulic rod four. The grinding wheel two 20 can be rotated by using the rotating motor two.

[0049] Furthermore, the height of the second grinding wheel 20 is the same as the height of the lower part 1 of the stepped glass; the top of the second grinding wheel 20 is provided with an upper edge 4, the bottom of the upper edge 4 is flush with the bottom of the first grinding wheel 22, and the bottom of the second grinding wheel 20 is provided with a lower edge 5; with this configuration, when the second grinding wheel 20 contacts the lower part of the stepped intermediate product stepped glass, the second grinding wheel 20 can simultaneously grind the upper edge 4 and the lower edge 5, thereby improving the production efficiency of the stepped glass.

[0050] The grinding structure three includes a hydraulic rod five embedded in the worktable 6. The other end of the hydraulic rod five is located above the worktable 6. The other end of the hydraulic rod five is fixedly connected to a support plate three 17. A rotating motor three is fixedly connected to the top of the other end of the support plate three 17. A grinding wheel three 18 is movably connected to the bottom of the other end of the support plate three 17. The end of the output shaft of the rotating motor three is fixedly connected to the middle of the top of the grinding wheel three 18.

[0051] The grinding wheel 3 18 includes two symmetrically arranged frustums. The taper of the frustum is the same as the taper of the upper edge 2 3. The distance between the bottom of the grinding wheel 3 18 and the top of the grinding wheel 1 22 is the same as the height of the upper edge 2 3. With this arrangement, the upper edge 2 3 can be directly ground using the grinding wheel 3 18.

[0052] All three support plates, namely 21, 19, and 17, are L-shaped, and the hydraulic rod 28 is fixedly connected to the vertical end of one of the support plates, 19, or 17. The vertical ends of all three support plates are telescopic, allowing the manufacturing machine to adapt to various sizes of stepped glass and improving its adaptability. In some embodiments of this application, the vertical ends of the support plates are electrically telescopic rods, and the horizontal ends are horizontal support plates.

[0053] The aforementioned dust removal structure includes a vacuum cleaner 29, a vacuum head 26, a blower head 24, a blower 25, and a hydraulic rod 27.

[0054] One end of the hydraulic rod 27 is fixedly connected to the top of the worktable 6, and the other end of the hydraulic rod 27 is fixedly connected to the dust blowing head 24. The dust blowing head 24 is located directly above the vacuum suction cup. Air outlet holes are evenly provided at the bottom of the inner cavity of the dust blowing head 24. A blower 25 is fixedly installed on the top of the dust blowing head 24. The air outlet of the blower 25 is connected to the inner cavity of the dust blowing head 24 through the air outlet pipe. Through the setting of the hydraulic rod 27, the extension and retraction of the hydraulic rod 27 can change the distance between the dust blowing head 24 and the vacuum suction cup. The operation of the blower 25 can blow outside air into the inner cavity of the dust blowing head 24. The air in the dust blowing head 24 can be discharged through the air outlet holes, and the air blown out of the air outlet holes can be directly blown onto the raw material being ground.

[0055] The top of each of the support plates 1 (21), 2 (19), and 3 (17) is fixed with a suction head 26. The suction head 26 is located above the workbench 6 and below the grinding wheel 1 (22), grinding wheel 2 (20), or grinding wheel 3 (18). The suction head 26 is connected to the air inlet of the vacuum cleaner 29 through the suction pipe 30. When the vacuum cleaner 29 is working, the air around the suction head 26 enters the vacuum cleaner 29, and the vacuum cleaner 29 filters the air.

[0056] As can be seen from the above description of the dust removal structure, the dust generated during the preparation of stepped glass using the stepped glass preparation machinery is blown by the airflow discharged from the dust blower 24 to the vicinity of the dust suction head 26, and the vacuum cleaner 29 filters the dust-laden air.

[0057] In summary, the steps for manufacturing stepped glass using the aforementioned stepped glass preparation machinery are as follows:

[0058] Step 1: The staff places the raw material for the stepped glass production that needs to be polished onto the vacuum suction cup;

[0059] Step 2: Hydraulic rod 15 retracts, causing the sealing cylinder 9, which is fixedly connected to it, to move downwards. During the downward movement of the sealing cylinder 9, the sealing column 10 moves downwards until the distance between the top of the sealing cylinder 9 and the top of the hollow disk 8 is the same as the distance between the bottom of the grinding wheel 20 and the top of the worktable 6. At this time, the top of the sealing column 10 separates from the top of the hollow disk 8. Vacuum pump 16 is started. When vacuum pump 16 is working, the raw material for producing stepped glass is connected to the vacuum suction cup under negative pressure. Hydraulic rod 14 extends until the top of the sealing cylinder 9 is flush with the top of the worktable 6. At this time, hydraulic rod 14 moves the raw material for producing stepped glass to the top of the worktable 6, and the bottom of the raw material for producing stepped glass is flush with the bottom of the grinding wheel 20.

[0060] Step 3: The power structure operates, and the turntable 7 rotates under the action of the power structure; the dust removal structure operates, and the blower 25 blows outside air into the dust blowing head 24. The gas sprayed from the dust blowing head 24 blows onto the stepped glass production raw material, blowing the dust around the stepped glass production raw material to the vicinity of the dust suction head 26. The vacuum cleaner 29 operates, and the air with dust around the dust suction head 26 is sucked into the vacuum cleaner 29, which filters the air.

[0061] Step 4: Grinding structures 1, 2, and 3 operate sequentially. In grinding structure 1, the rotating motor 23 drives the grinding wheel 22 to rotate. Under the action of hydraulic rod 28, the grinding wheel 22 contacts the raw material for stepped glass production. After the raw material is ground into a stepped shape, the grinding wheel 22 returns to its original position. In grinding structure 2, the grinding wheel 20 grinds the lower part of the stepped glass. After the lower part of the stepped glass is ground to form the upper edge 4 and lower edge 5, the grinding wheel 20 returns to its original position. In grinding structure 3, the grinding wheel 18 grinds the upper part of the stepped glass. After the upper edge 3 is ground to form the upper edge 3, the grinding wheel 18 returns to its original position. This completes the production of the stepped glass.

[0062] Step 5: The power structure stops working, and the turntable 7 stops rotating; hydraulic rod 14 retracts, and hydraulic rod 2 15 extends during the retraction of hydraulic rod 14, so that the top of the hollow disc 8 is flush with the top of the turntable 7 while the position of the sealing cylinder 9 remains unchanged; vacuum pump 16 stops working, and the staff removes the prepared stepped glass.

The method for preparing the stepped glass includes the following steps: Step 1: The staff places the raw material for the stepped glass production that needs to be polished onto the vacuum suction cup; Step 2: The hydraulic rod 2 (15) retracts, and the hydraulic rod 2 (15) drives the sealing cylinder (9) fixedly connected to it to move down. During the downward movement of the sealing cylinder (9), the sealing column (10) moves down until the distance between the top of the sealing cylinder (9) and the top of the hollow disk (8) is the same as the distance between the bottom of the grinding wheel 2 (20) and the top of the worktable (6). At this time, the top of the sealing column (10) separates from the top of the hollow disk (8). The vacuum pump (16) is started. The vacuum pump (16) works, and the raw material for producing stepped glass is connected to the vacuum suction cup under negative pressure. The hydraulic rod 1 (14) extends until the top of the sealing cylinder (9) is flush with the top of the worktable (6). Step 3: The power structure works, and the turntable (7) rotates under the action of the power structure; the dust removal structure works, the blower (25) blows the outside air into the dust blowing head (24), the gas sprayed from the dust blowing head (24) blows onto the stepped glass production raw material, and blows the dust around the stepped glass production raw material to the vicinity of the dust suction head (26), the vacuum cleaner (29) works, and the air with dust around the dust suction head (26) is sucked into the vacuum cleaner (29), and the vacuum cleaner (29) filters the air; Step 4: Grinding Structure 1, Grinding Structure 2, and Grinding Structure 3 work in sequence; the rotating motor 1 (23) in Grinding Structure 1 drives Grinding Wheel 1 (22) to rotate. Grinding Wheel 1 (22) contacts the raw material for stepped glass production under the action of Hydraulic Rod 3 (28). After the raw material for stepped glass production is ground into a stepped shape, Grinding Wheel 1 (22) resets; Grinding Wheel 2 (20) in Grinding Structure 2 grinds the lower part of the stepped glass. After the lower part of the stepped glass is ground into the upper edge 1 (4) and lower edge 5, Grinding Wheel 2 (20) resets; Grinding Wheel 3 (18) in Grinding Structure 3 grinds the upper part of the stepped glass. After the upper edge 2 (3) is ground into the upper part of the stepped glass, Grinding Wheel 3 (18) resets; thus, the production of stepped glass is achieved. Step 5: The power structure stops working, the turntable (7) stops rotating; the first hydraulic rod (14) retracts, and the second hydraulic rod (15) extends during the retraction of the first hydraulic rod (14), so that the top of the hollow disc (8) is flush with the top of the turntable (7) while the position of the sealing cylinder (9) remains unchanged. The vacuum pump (16) stops working, and the staff removes the finished stepped glass.
