A production equipment for high borosilicate glass flat-drawn special-shaped tubes

Abstract

This invention discloses a production equipment for high borosilicate glass flat-drawn shaped tubes, including a pressing and forming component, a lateral limiting component, a cooling component, a traction component, a cutting component, and a breaking component. The four rollers of the pressing and forming component compress the soft glass tube into a rectangular shaped tube. The limiting cylinder of the lateral limiting component supports the upper end of the tube to prevent it from falling and deforming. The cooling component accelerates the hardening of the tube. The traction component continuously moves the tube out of the heating furnace to avoid accumulation. The cutting component is linked to the rotating wheel through a crank rod, so that the cutting action and the movement of the tube are coordinated to ensure a smooth cut. The breaking component uses a counterweight to slightly bend the tube, and the cut marks formed by the cutting blade achieve the breaking and separation. This invention realizes continuous and stable production of shaped tubes, improving product quality and efficiency.

Description

Technical Field

[0001] This invention relates to the field of high borosilicate glass flat drawing technology, specifically to a high borosilicate glass flat drawing special-shaped tube production equipment. Background Technology

[0002] High borosilicate glass is widely used in solar thermal power generation, chemical pipelines, laboratory instruments and high-temperature windows due to its excellent thermal stability, chemical corrosion resistance and high mechanical strength.

[0003] As an important branch of borosilicate glass products, the forming quality of irregularly shaped tubes directly affects the safety and functional integration of downstream applications.

[0004] Currently, the mainstream production processes for high borosilicate glass tubes include the vertical drawing method (also known as the Dana method), the Verlo method, and the horizontal drawing method (also known as the flat drawing method). Among them, the vertical drawing method can produce high-precision round tubes, but it is difficult to directly form irregular cross-sections. It often requires secondary hot processing such as hot bending and forming to obtain irregular tubes. This not only has high energy consumption and low efficiency, but also easily produces defects such as stress concentration, uneven wall thickness, and surface microcracks. The horizontal drawing method has the potential to continuously produce irregular cross-section tubes because of its stable melt surface and easy design of the forming flow channel.

[0005] When using high borosilicate glass to manufacture shaped tubes in the flat drawing process, the shaped tubes are subjected to the combined effects of gravity, surface tension and traction during the flat drawing process. The lack of lateral restraint and forced shaping structure leads to the twisting, bending or cross-sectional distortion of the produced tubes. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: I. This invention uses four rollers to extrude and form a flexible glass tube, resulting in a near-rectangular cross-section. The glass tube then enters between two limiting cylinders, with the distance between the two cylinders slightly smaller than the distance between the four rollers. This increases the height of the glass tube, preventing the upper part from sagging under gravity before it cools and solidifies, thus preventing deformation. Simultaneously, a motor drives a belt to rotate, continuously moving the hardened glass tube and pulling it out of the furnace. This continuous process enables the production of shaped tubes and solves the problem of uneven surfaces caused by the tube accumulating in the furnace due to a lack of continuous movement.

[0016] Second, this invention utilizes the accelerated movement of the first crank rod, combined with the rotation of the belt, to make the hardened glass tube move continuously, thereby enabling the glass tube to be cut into a flat surface more effectively. Furthermore, through the linkage between the cutting component and the rotating wheel, the movement of the glass tube and the swing of the first crank rod are made more consistent. When producing tubes of different diameters, only the distance between the two rotating wheels needs to be finely adjusted, thus making it suitable for the production of special-shaped tubes of different sizes.

[0017] Third, this invention uses a counterweight to press down on one end of the glass tube, causing the glass tube to bend slightly. At the same time, the glass tube can be cut off by the cutting blade making a mark on the upper surface of the glass tube. The cut glass tube will fall onto a rubber frame. The lower end of the rubber frame is also equipped with a conveyor belt for transporting the glass tube in sections to facilitate the segmented transport and storage of the glass tube.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0021] Example 1, please refer to Figures 1 to 10This invention provides a production equipment for high borosilicate glass flat-drawn shaped tubes, including a pressing wheel 2, the surface of the pressing wheel 2 abutting against a glass tube 1, a through hole being opened on the end face of the pressing wheel 2, a rotating rod 3 being fixedly connected to the surface of the through hole, a connecting plate 4 being rotatably connected to the end surface of the rotating rod 3, a fixing plate 5 being fixedly connected to the end face of the connecting plate 4, a pressing and forming assembly being provided on the surface of the fixing plate 5, the pressing and forming assembly including a roller 20 disposed on the fixing plate 5 for pressing the glass tube 1 into a shaped tube, and a lateral limiting assembly being provided on the surface of the fixing plate 5, the lateral limiting assembly including a limiting cylinder 22 disposed on the side of the glass tube 1.

[0022] A cooling component and a traction component are also provided on the side of the side limiting component. The cooling component includes a shield 8 and a blower 23 provided on the side of the side limiting component to accelerate the cooling and hardening of the flexible glass tube 1. The traction component includes a rotating wheel 31 provided on the shield 8 and a belt 32 provided on the surface of the rotating wheel 31.

[0023] The pressing and molding assembly also includes a mounting block 19, the side of which is fixedly connected to the end face of a fixing plate 5. The end face of the fixing plate 5 has a through circular groove through which the glass tube 1 passes. A telescopic motor 16 is also fixedly connected to the surface of the mounting block 19. A connecting rod 21 is fixedly connected to the output end of the telescopic motor 16. The end surface of the connecting rod 21 away from the telescopic motor 16 is rotatably connected to the surface of the roller 20.

[0024] The lateral limiting assembly also includes a connecting frame 14 fixedly connected to the end face of the fixing plate 5, a placement frame 13 fixedly connected to the inner wall of the connecting frame 14, a fixing frame 15 fixedly connected to the upper end face of the placement frame 13, a sliding block 17 slidably connected to the inner wall of the fixing frame 15, the inner wall of the sliding block 17 being rotatably connected to the end of the limiting cylinder 22, the surface of the limiting cylinder 22 abutting against the side of the glass tube 1, and a threaded rod 18 rotatably connected to the upper end face of the sliding block 17. A through threaded groove is opened on the upper end face of the fixing frame 15, and the groove wall of the threaded groove is threadedly connected to the surface of the threaded rod 18.

[0025] More specifically, in this embodiment: the glass tube 1 is drawn out from the heating furnace. At this time, the cross-section of the glass tube 1 is approximately circular. Then, the glass tube 1 enters the circular groove between the fixed plate 5 through the pressing roller 2. It is formed by the extrusion of four rollers 20. The cross-section of this soft glass tube 1 becomes approximately rectangular. Then, the glass tube 1 enters between two limiting cylinders 22. At the same time, the distance between the two limiting cylinders 22 is slightly smaller than the distance between the four rollers 20, thereby increasing the upper end of the glass tube 1. This prevents the upper part of the glass tube 1 from falling under the action of gravity before it is cooled and formed, thus preventing the glass tube 1 from deforming.

[0026] Since the cooling assembly also includes a placement platform 6, which is located on the side of the placement rack 13, a rolling frame 7 is fixedly connected to the upper end of the placement platform 6, the surface of the rolling frame 7 abuts against the lower surface of the glass tube 1, the lower end of the placement platform 6 abuts against the lower end of the blower 23, a through vent 24 is opened on the upper end of the placement platform 6, the vent 24 is connected to the surface of the blower 23, and the upper end of the placement platform 6 is also rotatably connected to one end of the shield 8.

[0027] Afterwards, the glass tube 1 enters the rolling frame 7 on the placement table 6. At this time, the shield 8 is closed, and the blower 23 is started to blow air between the shield 8 and the placement table 6. At the same time, the turbulence effect of the shield 8 allows the glass tube 1 to cool and form more quickly on the placement table 6. After forming, the glass tube 1 passes between two belts 32. The motor 36 drives the rotating wheel 31 to rotate the belts 32, so that the hardened glass tube 1 continues to move, thereby continuously pulling the soft glass tube 1 out of the heating furnace to realize the process of continuous production of special-shaped tubes.

[0028] Through extrusion molding by four rollers 20, the cross-section of this flexible glass tube 1 becomes approximately rectangular. The glass tube 1 then enters between two limiting cylinders 22. The distance between the two limiting cylinders 22 is slightly smaller than the distance between the four rollers 20, thereby increasing the height of the glass tube 1. This prevents the upper part of the glass tube 1 from falling under the influence of gravity before it has cooled and formed, thus preventing deformation of the glass tube 1.

[0029] Meanwhile, the traction assembly also includes an equipment platform 9. An equipment frame 38 is fixedly connected to the upper end of the equipment platform 9. The surface of the equipment frame 38 is provided with a rotating groove. A fixed rod 49 is rotatably connected to the opening of the rotating groove. The surface of the fixed rod 49 is fixedly connected to the inner wall of the rotating wheel 31. There are four rotating wheels 31 in total. The surface of the equipment frame 38 is provided with four rotating grooves. The four rotating grooves correspond one-to-one with the fixed rods 49 on the four rotating wheels 31. The rotating wheels 31 are divided into upper and lower groups. A belt 32 is sleeved on the surface of each group of rotating wheels 31. The surface of the belt 32 abuts against the surface of the glass tube 1. A motor 36 is fixedly connected to the end of the fixed rod 49. The outer surface of the motor 36 is fixedly connected to the side of the equipment frame 38. A toothed ring 48 is fixedly connected to the fixed rod 49 on the rotating wheel 31 on the side of the motor 36. A toothed ring 2 is meshed with the toothed surface of the toothed ring 48. The inner wall of the toothed ring 2 is fixedly connected to the fixed rod 49 on the rotating wheel 31 below the toothed ring 48.

[0030] Thus, the rotating wheel 31 driven by the motor 36 drives the belt 32 to rotate, so that the hardened glass tube 1 moves continuously, thereby continuously pulling the soft glass tube 1 out of the heating furnace, so as to realize the process of continuous production of special-shaped tubes. It also solves the problem that in the production process, the special-shaped tube does not move continuously, which causes the soft glass tube 1 to accumulate in the heating furnace and cause the surface of the glass tube 1 to be uneven.

[0031] Example 2: Based on the above examples, the traction assembly is further provided with a cutting assembly, which includes a cutting blade 10. The cutting blade 10 operates together with the traction assembly to cut the glass tube 1.

[0032] The cutting assembly also includes a bevel gear 50, the end face of which has a through slot. The wall of the slot is fixedly connected to the surface of a fixing rod 49 on which a toothed ring 48 is mounted. The tooth surface of the bevel gear 50 meshes with a bevel gear 52, the end face of which has a through opening. A rotating shaft 39 is rotatably connected to the wall of the through opening. A fixing bracket 51 is rotatably connected to the lower end face of the rotating shaft 39. The surface of the fixing bracket 51 is flush with the surface of the equipment frame 38. The upper end is fixedly connected to the rotating shaft 39. A small toothed ring 47 is fixedly connected to the upper end face of the rotating shaft 39. A large toothed ring 33 is meshed with the tooth surface of the small toothed ring 47. A rotating shaft 37 is fixedly connected to the inner wall of the large toothed ring 33. A mounting bracket 30 is rotatably connected to the lower end face of the rotating shaft 37. The surface of the mounting bracket 30 is fixedly connected to the upper end of the equipment frame 38. A rotating shaft 29 is also rotatably connected to the upper end face of the mounting bracket 30. A crank rod 28 is fixedly connected to the surface of the rotating shaft 29.

[0033] The cutting assembly also includes a cam 34, the lower end face of which is fixedly connected to the upper end face of the rotating shaft 37. The upper end face of the crank 28 has a through groove, and the groove wall is slidably connected to a sliding column 27. The lower end face of the sliding column 27 is fixedly connected to the upper end face of the cam 34. The end of the crank 28 away from the rotating shaft 29 has a through mounting groove, and the groove wall is slidably connected to the surface of the cutting blade 10. The surface of the cutting blade 10 is also fixedly connected to a sloping plate 26, and the surface of the sloping plate 26 is slidably connected to the groove wall of the groove. A fixing sleeve 25 is sleeved on the surface of the sloping plate 26, and a spring 35 is fixedly connected to the inner wall of the fixing sleeve 25. A fixing plate 46 is fixedly connected to the lower end of the spring 35, and the lower end face of the fixing plate 46 is fixedly connected to the upper end face of the cutting blade 10.

[0034] More specifically, in this embodiment: Motor 36 causes the rotating wheel 31 to rotate, and simultaneously causes the fixed rod 49 to rotate counterclockwise. The counterclockwise rotation of the fixed rod 49 causes the bevel gear 50 to rotate counterclockwise, which in turn drives the meshing bevel gear 52 to rotate counterclockwise. The counterclockwise rotation of bevel gear 52 drives the small gear ring 47 to rotate counterclockwise via rotating shaft 39. The counterclockwise rotation of the small gear ring 47 drives the large gear ring 33 to rotate clockwise, thereby causing the cam 34 to rotate counterclockwise via rotating shaft 37. The counterclockwise rotation of the cam 34 causes... The sliding column 27 moves towards the side of the rotating shaft 29. Since the sliding column 27 revolves around the rotating shaft 37, the rotation speed of the sliding column 27 remains constant. When the sliding column 27 gets closer to the rotating shaft 29, it will drive the crank 28 to swing around the rotating shaft 29 at a faster speed, making a groove on the upper end surface of the glass tube 1. When the sliding column 27 moves away from the rotating shaft 29, it will abut against the inclined surface of the inclined groove plate 26 to lift the cutting blade 10 and prevent it from contacting the glass. By utilizing the accelerated movement of the crank 28 in conjunction with the rotation of the belt 32, the hardened glass tube 1 moves continuously, thereby enabling the glass tube 1 to be cut into a flat surface more effectively. Furthermore, through the linkage between the cutting component and the rotating wheel 31, the movement of the glass tube 1 and the swing of the crank 28 become more consistent. When producing tubes of different diameters, only the distance between the two rotating wheels 31 needs to be finely adjusted, thus making it suitable for the production of special-shaped tubes of different sizes.

[0035] Furthermore, the end of the cutting blade 10 is made of carbide wheel material, which has the characteristics of good cutting performance, long service life and high stability, making it suitable for the continuous production function of this device.

[0036] Example 3: Based on the above examples, a break-off component is also provided on the side of the traction component. The break-off component includes a counterweight cylinder 40 provided on the side of the belt 32.

[0037] The breaking assembly also includes a mounting bracket 3 12. A fixing block 1 45 is fixedly connected to the surface of the mounting bracket 3 12. A rotating bracket 1 44 is rotatably connected to the surface of the fixing block 1 45. A through limiting groove is opened on the upper end face of the rotating bracket 1 44. A limiting rod 43 is slidably connected to the groove wall. A roller frame 41 is fixedly connected to the lower end face of the limiting rod 43. A spring 2 42 is fixedly connected to the upper surface of the roller frame 41. The upper end of the spring 2 42 is fixedly connected to the lower end face of the rotating bracket 1 44. The inner wall of the roller frame 41 is rotatably connected to the end of the counterweight cylinder 40. A rubber frame 11 is also provided on the lower side of the counterweight cylinder 40.

[0038] More specifically, in this embodiment: when the glass tube 1 moves, it will abut against the surface of the counterweight cylinder 40, and then the counterweight cylinder 40 will rotate around the fixed block 45 as an axis, so that the counterweight cylinder 40 presses down on one end of the glass tube 1, causing the glass tube 1 to bend slightly. At the same time, with the cutter 10 making a groove on the upper end surface of the glass tube 1, the glass tube 1 can be cut off. The cut glass tube 1 will fall onto the rubber frame 11. The lower end of the rubber frame 11 is also provided with a conveyor belt for transporting the glass tube 1, so as to facilitate the segmented transport and storage of the glass tube 1.

[0039] Working Principle: This high borosilicate glass flat-drawn shaped tube production equipment operates as follows: Glass tube 1 is drawn out of the heating furnace, at which point its cross-section is approximately circular. Then, glass tube 1 enters the circular groove between the fixed plate 5 via the pressing roller 2. It is then extruded and shaped by four rollers 20, transforming the soft glass tube 1 into an approximately rectangular cross-section. Next, glass tube 1 enters between two limiting cylinders 22, with the distance between the two limiting cylinders 22 slightly smaller than the distance between the four rollers 20. This increases the height of the upper end of the glass tube 1, preventing it from falling under gravity before it has cooled and formed. The problem of deformation of glass tube 1 is addressed by placing glass tube 1 onto the rolling frame 7 on the placement table 6. At this point, the shield 8 is closed, and the blower 23 is started to blow air between the shield 8 and the placement table 6. The turbulence created by the shield 8 helps the glass tube 1 cool and solidify more quickly on the placement table 6. After solidification, the glass tube 1 passes between two belts 32. Motor 36 drives the rotating wheel 31 to rotate the belts 32, causing the hardened glass tube 1 to move continuously, thus continuously pulling the soft glass tube 1 out of the heating furnace. This achieves a continuous production process for shaped tubes. Motor 36 rotates the rotating wheel 31, simultaneously causing the fixing rod 49 to rotate counterclockwise. Counterclockwise rotation causes bevel gear 50 to rotate counterclockwise, which in turn drives bevel gear 52 to rotate counterclockwise. The counterclockwise rotation of bevel gear 52 drives small gear ring 47 to rotate counterclockwise via rotating shaft 39. The counterclockwise rotation of small gear ring 47 drives large gear ring 33 to rotate clockwise, which in turn drives cam 34 to rotate counterclockwise via rotating shaft 37. The counterclockwise rotation of cam 34 causes sliding column 27 to move towards one side of rotating shaft 29. Since sliding column 27 revolves around rotating shaft 27, its rotational speed remains constant. As sliding column 27 gets closer to rotating shaft 29, it drives crank rod 28 to swing around rotating shaft 29 at a faster speed, thus impacting the upper surface of glass tube 1. The scribing marks allow the sliding column 27 to move away from the rotating shaft 29. The sliding column 27 then presses against the inclined surface of the inclined groove plate 26, lifting the cutting blade 10 and preventing it from contacting the glass. As the glass tube 1 moves, it presses against the surface of the counterweight cylinder 40, causing the counterweight cylinder 40 to rotate around the fixed block 45. This presses down on one end of the glass tube 1, causing it to bend slightly. Simultaneously, the scribing marks on the upper surface of the glass tube 1, combined with the cutting blade 10, cut the glass tube 1 off. The cut glass tube 1 falls onto the rubber frame 11, which has a conveyor belt at its lower end for convenient segmented transport and storage.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
