Description

Technical Field

[0001] The present invention belongs to the technical field of glass forming machines, and particularly relates to a surface treatment device for a high borosilicate glass tube forming device. Background Art

[0002] Due to its excellent heat resistance, chemical stability and light transmittance, high borosilicate glass is widely used in the fields of optical instruments, high-end tableware and special glass tube production. The glass blow molding machine is an indispensable device in the production process of glass products, and it undertakes the important task of shaping molten glass into an accurate tube shape. During operation, the molten glass is pushed into the forming frame and formed through precise control.

[0003] For example, a lightweight glass container rapid forming system and method disclosed in the national patent publication number CN115650558A. The invention pours the glass molten liquid in the melter into the first half mold and the second half mold. The primary mold mechanism makes the glass molten liquid into the primary mold of the glass container, and the blow molding mechanism blows the primary mold of the glass container into a formed glass container. The transportation mechanism transports the formed glass container for heat treatment. The present invention has the advantages of high automation and high efficiency.

[0004] However, the following problems still exist when the traditional device is used: High borosilicate glass has a certain viscosity in the molten state. Especially in the forming temperature range, the viscosity of the glass liquid will increase as the temperature decreases. And the forming sleeve is exposed to the air in the factory before processing, and it is easy to attach dust. During subsequent processing, it is very easy to adhere to the outer wall of the glass tube through viscosity, affecting the surface forming treatment of the glass tube. Therefore, it is necessary to clean the dust at the forming sleeve in time, thereby improving the forming rate of the glass tube. Summary of the Invention

[0038] Example 1, please refer to Figures 1 to 19 , the present invention provides a technical solution: a surface treatment device for a high borosilicate glass tube forming device, including a forming machine frame 1, characterized in that: the top workbench of the forming machine frame 1 clamps a high borosilicate glass tube 2, and two supporting bases 3 are fixedly connected to the outer wall of the top workbench of the forming machine frame 1 at one side outer wall position of the high borosilicate glass tube 2. A screw rod stepping motor 4 is fixedly connected to the outer wall of one side of the two supporting bases 3. A threaded screw rod 5 is fixedly connected to the axis of the screw rod stepping motor 4. The supporting base 3 is provided with a through hole with both outer walls communicating. The outer wall of the threaded screw rod 5 communicates with the inner wall of the through hole. A rotating shaft 7 is fixedly connected to the outer wall of the threaded screw rod 5 away from the screw rod stepping motor 4. A forming tube rack 6 is arranged on the outer wall of one side of the supporting base 3. The inner wall of the forming tube rack 6 is rotatably connected to the outer wall of the rotating shaft 7. A working cavity 9 is opened on the outer wall of the forming tube rack 6 away from the supporting base 3. A forming fixture 8 is fixedly installed on the inner wall of the working cavity 9. Two dust-proof plates 12 are respectively slidably and movably connected to the upper and lower outer walls of the forming fixture 8. The inner wall of the dust-proof plate 12 is movably attached to the outer wall of one side of the forming fixture 8. The outer walls of the two dust-proof plates 12 are movably attached. A flow ventilation duct 13 communicating with the inner wall is opened on the outer wall of one side of the top of the dust-proof plate 12. Connecting pipe grooves 16 communicating with the working cavity 9 are opened on the outer walls of both sides of the forming tube rack 6. An air supply main pipe 10 is slidably connected to the inner walls of the two connecting pipe grooves 16 on both sides. A plurality of shunt valve pipes 11 are fixedly connected to the outer wall of the air supply main pipe 10. One end of the outer wall of the shunt valve pipe 11 is communicated with the inner wall of the flow ventilation duct 13 through the dust-proof plate 12. An air compressor 14 and a collection box 15 are fixedly installed on the outer wall of the top of the forming machine frame 1. The output pipe of the air compressor 14 is communicated with the two air supply main pipes 10 at the upper end of the forming tube rack 6. The discharge pipe of the air compressor 14 is communicated with the two air supply main pipes 10 at the lower end of the forming tube rack 6. An installation plate 48 is arranged on the outer wall of the top of the forming machine frame 1. A driving guide rail 47 is threadedly connected to the outer wall of the bottom of the installation plate 48. An installation plate 48 is arranged on the outer wall of the top of the forming machine frame 1. A driving motor is fixedly connected to the outer wall of one end of the driving guide rail 47. A driving fixture 49 is fixedly connected to the outer wall of the top of the installation plate 48. The inner wall of the driving fixture 49 is movably clamped to the outer wall of the forming machine frame 1.

[0039] In the present invention, after the driving fixture 49 holds the forming machine frame 1 in a molten state, the driving motor 50 is started to drive the mounting plate 48 to move horizontally, moving the forming machine frame 1 to the center position between the two forming pipe racks 6. At the same time, the screw rod stepping motor 4 is started to make the threaded screw rod 5 expand and contract in a threaded manner, driving the two forming pipe racks 6 to move to the center and fit over the outer wall of the forming machine frame 1, performing press forming on the forming machine frame 1. After the forming machine frame 1 is completely shaped, the screw rod stepping motor 4 drives the threaded screw rod 5 to rotate, causing the two forming pipe racks 6 to move back and disengage from the outer wall of the forming machine frame 1. While moving back, the two dust-proof plates 12 slide out of the working cavity 9 and move up and down to cover the inner wall of the forming fixture 8, preventing the impurity air in the factory from adhering to the inner wall of the forming fixture 8. Moreover, the air compressor 14 is started to generate air pressure, and the air flow is gradually transmitted into the forming fixture 8 through the main ventilation pipe 10, the shunt valve pipe 11, and the ventilation duct 13, blowing the inner wall of the forming fixture 8 to blow off the dust and impurities that may adhere to the inner wall of the forming fixture 8 and discharging them into the collection box 15 along with the air flow. In the present invention, dust-proof filters are installed at the ventilation ends of the air compressor 14, which are conventional devices available on the market and are regularly inspected and cleaned by the machine crew workers. This is not elaborated in the present invention. Through this device, the exposure of the forming fixture 8 to the air in the factory before processing can be reduced, preventing the adhesion of dust, and at the same time, the dust that may exist in the forming fixture 8 can be cleaned in time, thereby improving the forming rate of the forming machine frame 1.

[0040] Embodiment 2, on the basis of Embodiment 1, the vertical cross-section of the forming pipe rack 6 is in the shape of a "7". A storage groove 33 is formed on one inner wall of the forming pipe rack 6. Moving grooves 41 are formed on both inner walls of the storage groove 33. The same moving block 42 is slidably connected to the inner walls of the two moving grooves 41. A guiding piece 40 is fixedly connected to the bottom outer wall of the moving block 42. The guiding piece 40 is in an arc shape. A rotating roller 44 is fixedly connected to the inner wall of the storage groove 33. The outer wall of the rotating roller 44 is movably attached to the outer wall of the guiding piece 40. A first folding plate 34 is provided at the bottom of the storage groove 33. One end outer wall of the first folding plate 34 is fixedly connected to a spring hinge 35. The end outer wall of the spring hinge 35 far from the first folding plate 34 is fixedly hinged to a second folding plate 36. Connecting hinges are fixedly connected to the end outer walls of the first folding plate 34 and the second folding plate 36 far from the spring hinge 35. The first folding plate 34 is hinged to the bottom inner wall of the storage groove 33 through the connecting hinge. The second folding plate 36 is hinged to the bottom inner wall of the guiding piece 40 through the connecting hinge. A winding cavity 37 is formed inside the forming pipe rack 6. A guiding groove 38 communicating with the winding cavity 37 is formed on one inner wall of the storage groove 33. A storage rod 22 is rotatably connected to the inner wall of the winding cavity 37. A tension belt 39 is fixedly connected to one side outer wall of the storage rod 22. The end outer wall of the tension belt 39 far from the storage rod 22 passes through the guiding groove 38 and is fixedly connected to the outer wall of the spring hinge 35.

[0041] In the present invention, the guide piece 40 is a flexible and resilient iron sheet, and its original shape is an arc shape, rather than a straight plate that is compressed into an arc shape. By splicing the two guide pieces 40 together, a group of wind flow guide channels that match the curvature of the inner wall of the forming fixture 8 are formed, and the wind flow is compressed, and can be blown in a streamlined manner along the inner wall of the forming fixture 8 throughout the entire process, thereby improving the dust blowing efficiency and avoiding air turbulence on the inner wall of the forming fixture 8. When the two forming pipe racks 6 converge toward the position of the forming machine rack 1, the storage rod 22 will rotate, and the tension belt 39 will be gradually wound into the winding chamber 37 by the rotation. At this time, the spring hinge 35 is pulled by the spring hinge 35, and because one end of the folding plate 2 36 is pressed by the guide piece 40, the wind flow is compressed. The folding plate 1 34 and the folding plate 2 36 are folded into the storage groove 33 with the spring hinge 35 as the axis, and the guide piece 40 is against the outside of the storage groove 33. The superimposed width of the guide piece 40, the folding plate 2 36 and the folding plate 1 34 is the same width as the storage groove 33. At this time, because the angle of the guide piece 40 changes and the arc angle formed by the movable groove 41 is within the bending value of the guide piece 40, and at the same time, affected by the lifting of the bottom folding plate 2 36 and the pressure of the forming pipe rack 6 on the storage groove 33 when the dustproof plate 12 moves upward, the guide piece 40 will slide into the movable groove 41. At this point, the dustproof plate 12 is completely flush with the working chamber 9. When the two forming pipe racks 6 are completely aggregated, the two opposite dustproof plates 12 will press against each other and move into the working chamber 9 to complete the storage.

[0042] Embodiment 3. On the basis of Embodiment 2, sliding grooves 17 are provided on the inner walls of both sides of the forming pipe rack 6. A pressing plate 19 is slidably connected to the inner wall of the sliding groove 17. One outer wall of the pressing plate 19 is flush with one outer wall of the forming pipe rack 6. A limiting spring 18 is fixedly connected to one outer wall of the pressing plate 19. One end of the limiting spring 18 away from the pressing plate 19 is fixedly connected to the inner wall of the sliding groove 17. A groove 20 is provided on one outer wall of the pressing plate 19. A connecting rack 21 is fixedly connected to one inner wall of the groove 20. Annular grooves 43 are provided on the outer walls of both sides of the forming pipe rack 6. Both ends of the outer wall of the receiving rod 22 pass through the inner wall of the winding cavity 37 and are communicated with the annular groove 43. A connecting gear 23 is fixedly connected to the receiving rod 22 located in the annular groove 43. The outer wall of the connecting gear 23 is meshed with the outer wall of the connecting rack 21. A working chamber 24 is provided inside one side of the forming pipe rack 6. Two sprockets one 25 are fixedly connected to the outer wall of the rotating shaft 7 located in the working chamber 24. Installation chambers 32 are provided inside both the upper and lower ends of the forming pipe rack 6. Rotating rods 28 communicated with the working chamber 24 are rotatably connected to both ends of the inner wall of the installation chamber 32. A sprocket two 27 is fixedly connected to one end of the outer wall of the rotating rod 28. A belt 26 is meshed with the outer walls of the two sprockets two 27 and the sprocket one 25 respectively. A helical gear one 30 is fixedly connected to one end of the outer wall of the rotating rod 28 away from the sprocket two 27. A helical gear two 31 is rotatably connected to the bottom inner wall of the installation chamber 32. The helical gear two 31 is meshed with the helical gear one 30. A threaded limiting post 29 is rotatably connected to the inner wall of the working cavity 9. One end of the outer wall of the threaded limiting post 29 passes through the working cavity 9 and is fixedly connected to the bottom outer wall of the helical gear two 31. A strip-shaped communication cavity 45 communicated with the bottom outer wall is provided on the top outer wall of the dust-proof plate 12. A semi-threaded communication cavity 46 is provided on one outer wall of the strip-shaped communication cavity 45. The inner wall of the semi-threaded communication cavity 46 is meshed with the outer wall of the threaded limiting post 29.

[0043] In the present invention, when two formed pipe racks 6 converge towards the position of the forming machine frame 1, the threaded lead screw 5 is screwed out by starting the lead screw stepping motor 4. The rotation of the two threaded lead screws 5 drives the synchronous rotation of the first sprocket 25 in the working chamber 24. Further, the first sprocket 25 drives the rotation of two helical gears through the belt 26 and the rotating rod 28, and the second helical gear 31 further drives the rotation of the threaded limit post 29. At this time, the dust-proof plate 12 is in a closed state on the inner wall of the forming fixture 8, and the semi-threaded communication cavity 46 is threadedly engaged with the threaded limit post 29. The rotation of the threaded limit post 29 drives the dust-proof plate 12 to move vertically upward. During the upward movement, the first folding plate 34 engages with the connecting rack 21 to drive the synchronous rotation of the receiving rod 22. The rotation of the receiving rod 22 synchronously presses the guide piece 40 into the receiving groove 33 until the dust-proof plate 12 completely moves to the same horizontal height as the working chamber 9. The pressing plate 19 completely presses against one side inner wall of the dust-proof plate 12. At this time, the two formed pipe racks 6 are completely converged, and the two opposite dust-proof plates 12 press against each other and the pressing plate 19 slides in the chute 17. The threaded limit post 29 also disengages from the semi-threaded communication cavity 46 and enters the strip-shaped communication cavity 45, so that the pressing plate 19 is completely received into the working chamber 9.

[0044] The working principle and use process of the present invention: In the present invention, after the driving fixture 49 clamps the molding machine frame 1 in the molten state, the driving motor 50 is started to drive the mounting plate 48 to move horizontally to move the molding machine frame 1 to the center position of the two molding tube racks 6. At the same time, the screw stepper motor 4 is started to extend and retract the threaded screw 5 to drive the two molding tube racks 6 to move in the center and fit on the outer wall of the molding machine frame 1 to press and form the molding machine frame 1. After the molding machine frame 1 is completely finalized, the screw stepper motor 4 drives the threaded screw 5 to rotate, so that the two molding tube racks 6 move back and away from the outer wall of the molding machine frame 1. While moving back, the two dustproof plates 12 slide out of the working chamber 9 and move up and down to cover the inner wall of the molding fixture 8 to avoid The impure air in the factory adheres to the inner wall of the forming fixture 8, and the air compressor 14 is started to create air pressure, and the air flow is gradually transmitted to the forming fixture 8 through the ventilation main pipe 10, the diverter valve pipe 11 and the air flow duct 13, and the inner wall of the forming fixture 8 is blown to blow off the dust impurities that may be attached to the forming fixture 8, and discharged into the collection box 15 with the air flow. In the present invention, the ventilation end of the air compressor 14 is equipped with a dust filter, which is a conventional device already available on the market. The unit workers regularly check and clean it, and the present invention will not repeat it. Through this device, the exposure of the forming fixture 8 to the air in the factory before processing can be reduced to avoid dust adhesion. At the same time, the dust that may exist in the forming fixture 8 can be cleaned in time, thereby improving the forming rate of the forming machine frame 1. In the figure, the guide piece 40 is a metal sheet with a certain flexibility and resilience. The original shape is an arc shape, but the straight plate is compressed into an arc shape. Through the mutual splicing of the two guide pieces 40, a group of wind flow guiding channels that match the curvature of the inner wall of the forming fixture 8 are combined to compress the wind flow, so that the inner wall of the forming fixture 8 can be fitted with streamlined blowing throughout the process, thereby improving the dust blowing efficiency and avoiding air turbulence on the inner wall of the forming fixture 8. When the two forming pipe racks 6 converge toward the position of the forming machine frame 1, the storage rod 22 will rotate, and the tension belt 39 will be gradually wound into the winding chamber 37 through rotation. At this time, the spring hinge 35 is pulled by the spring hinge 35, and because one end of the folding plate 36 is pressed by the guide piece 40, the folding plate 1 34 and the folding plate 2 36 are elastically moved. The spring hinge 35 is axially folded into the storage groove 33, and the guide piece 40 is against the outside of the storage groove 33. The superimposed width of the guide piece 40, the folding plate 2 36 and the folding plate 1 34 is the same as the storage groove 33. At this time, because the angle of the guide piece 40 changes, and the arc angle formed by the movable groove 41 is within the bending value of the guide piece 40, and at the same time, it is affected by the lifting of the bottom folding plate 2 36 and the pressure of the forming pipe rack 6 on the storage groove 33 when the dustproof plate 12 moves up, the guide piece 40 will slide into the movable groove 41, and the dustproof plate 12 is completely flush with the working chamber 9. When the two forming pipe racks 6 are completely aggregated, the two opposing dustproof plates 12 will press each other and move into the working chamber 9 to complete the storage. In the present invention, when the two forming pipe racks 6 are aggregated to the position of the forming machine frame 1,It is to thread out the threaded lead screw 5 by starting the lead screw stepper motor 4. The rotation of the two threaded lead screws 5 will drive the first sprocket 25 to rotate synchronously in the working bin 24. Further, the first sprocket 25 drives the rotation of two helical gears through the belt 26 and the rotating rod 28, and the second helical gear 31 further drives the threaded limit post 29 to rotate. At this time, the dust-proof plate 12 is in a closed state on the inner wall of the forming fixture 8, and the semi-threaded communication cavity 46 will be threadedly engaged with the threaded limit post 29. The rotation of the threaded limit post 29 drives the dust-proof plate 12 to move vertically upward. During the upward movement, the first folding plate 34 will be engaged with the connecting rack 21 to drive the storage rod 22 to rotate synchronously. The rotation of the storage rod 22 synchronously presses the guide piece 40 into the storage groove 33 until the dust-proof plate 12 completely moves to the same horizontal height as the working cavity 9. The pressing plate 19 will completely press against one side inner wall of the dust-proof plate 12. At this time, the two forming pipe racks 6 are completely polymerized, and the two opposite dust-proof plates 12 will press against each other and the pressing plate 19 slides in the chute 17. The threaded limit post 29 will also disengage from the semi-threaded communication cavity 46 and enter the strip-shaped communication cavity 45, so that the pressing plate 19 is completely received into the working cavity 9.

The scope of the present invention is defined by the appended claims and their equivalents.
