Abstract
Description
Technical Field
[0001] This invention relates to the field of glass production, and more specifically, to an annealing mechanism for producing borosilicate pharmaceutical glass. Background Technology
[0002] Borosilicate glass for pharmaceutical use is a special type of glass, often referred to as "Chinese medicine glass" or "borosilicate glass". It is an exceptionally high-quality glass product, mainly used in the manufacture of medical devices such as infusion bottles, syringes, and blood sampling tubes. Compared with ordinary glass, Chinese medicine glass has several distinct advantages, including better high-temperature resistance, stronger chemical resistance, higher transparency, and greater stability.
[0003] Annealing is also required in the production of borosilicates. Simply put, annealing is the process of heating glass to a suitable temperature and then slowly cooling it to room temperature. This allows the internal structure and stress of the glass to gradually return to equilibrium, thereby improving the mechanical strength and physical properties of the glass, making it more tough and durable.
[0004] Currently, the most common glass annealing mechanism is to place the glass in a furnace and anneal it using external heating. Because the glass is only heated by an external heat source during the annealing process, the internal temperature distribution of the glass is uneven, which can easily lead to internal stress and deformation, affecting the quality and stability of the glass.
[0005] To address the aforementioned issues, some novel annealing mechanisms have been proposed, such as a device that uses infrared radiation to anneal glass. However, such devices can only confine the heat source to a specific area and cannot heat the entire glass uniformly. Therefore, it is necessary to propose a new type of glass annealing mechanism to achieve a more uniform annealing effect, reduce energy consumption, and improve production efficiency. Summary of the Invention

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0036] Example 1:
[0037] Please see Figure 1-8 An annealing mechanism for producing borosilicate pharmaceutical glass includes an annealing chamber 1. The top of the annealing chamber 1 is equipped with an opening and closing door 2, which is made of heat-insulating material. This design ensures that the opening and closing door 2 maintains the internal temperature of the annealing chamber 1 during glass annealing. After the heating block 3 has finished heating, the opening and closing door 2 can be opened to allow the glass to cool naturally. The heating block 3 is located inside the annealing chamber 1, and a transmission bar 6 is also installed inside the annealing chamber 1. The transmission bar 6 is connected to a drive synchronization mechanism, which drives the transmission bar 6 to rotate. The top of the transmission bar 6... A fixed column 8 is rotatably connected. The top of the fixed column 8 has a receiving cavity with an upper opening. A sliding column 9 is installed inside the receiving cavity. The upper part of the sliding column 9 extends to the upper side of the fixed column 8 through the upper opening of the receiving cavity. Multiple springs 10 are provided on the outer side of the sliding column 9. An installation strip 11 is installed on the outer side of the springs 10. The installation strip 11 is arc-shaped. This design makes it easier to install the glass on the installation strip 11 and reduces the degree of damage to the glass. This allows the glass to be effectively installed on the installation strip 11, ensuring the actual effect of annealing.
[0038] A guide mechanism is provided on the outside of the fixed column 8. The guide mechanism is used to drive the fixed column 8 to rotate. A control mechanism is installed on the outside of the sliding column 9. The control mechanism is used to drive the sliding column 9 to move up and down reciprocally.
[0039] See Figure 4 The drive synchronization mechanism includes two rotating columns 4 rotatably connected to the inside of the annealing chamber 1, and a drive shaft 5 is provided on the outer side of each of the two rotating columns 4. The drive bar 6 is installed on the outer side of the drive shaft 5. A motor 7 is installed at the bottom of the annealing chamber 1 and at the bottom of one of the rotating columns 4. The output end of the motor 7 is connected to one of the rotating columns 4. When the motor 7 is started, it can synchronously drive the rotating column 4 to rotate, and then drive the drive shaft 5 to rotate through the rotating column 4. Through the mutual connection between the drive shaft 5 and the drive bar 6, the rotating column 4 and the drive shaft 5 can drive the drive bar 6 to rotate when they rotate, thereby driving the mounting bar 11 on the drive bar 6 to revolve, and thus driving the glass to rotate. When the glass rotates, the heating degree of each surface of the glass can be more uniform, further ensuring the annealing effect.
[0040] In some embodiments, see Figure 5-6 The guiding mechanism includes a first gear 15, which is fixed to the outside of the fixed column 8. A connecting and fixing base plate 24 is installed on the inside of the annealing chamber 1 and outside the two rotating columns 4. At least two fixing plates 12 are provided on the top of the connecting and fixing base plate 24. An annular strip 13 is fixed on the side of the fixing plate 12 near the first gear 15, and the fixing plate 12 is used to support the annular strip 13. An annular tooth 14 that meshes with the first gear 15 is provided on the inside of the annular strip 13. When the transmission bar 6 runs, it can drive the fixed column 8 to move, which in turn drives the first gear 15 to move. When the first gear 15 moves, it can mesh with the annular strip 13, so that the first gear 15 can rotate, which in turn drives the fixed column 8 to rotate, thereby driving the glass on the mounting bar 11 to rotate, so that the heat received by the glass is more uniform, thus ensuring the toughness of the glass during annealing.
[0041] In some embodiments, see Figure 5 and Figure 7The control mechanism includes a second gear 16, which is located outside the sliding column 9 and rotatably connected to the fixed column 8. The diameter of the second gear 16 is smaller than that of the first gear 15. This arrangement ensures that the rotation frequency and amplitude of the second gear 16 and the first gear 15 are inconsistent, thereby preventing the fixed column 8 and the sliding column 9 from moving synchronously and ensuring the smooth operation of the entire mechanism. Multiple first toothed plates 17 are located on one side of the top of the fixed plate 12, corresponding to the position of the second gear 16. These first toothed plates 17 are connected to the top of the fixed base plate 24 and located away from the second gear 16. A connecting plate 18 is fixed on one side of 7. A plurality of second tooth plates 19 that mesh with the second gear 16 are provided on one side of the top of the connecting plate 18. The first tooth plate 17 and the second tooth plate 19 are spaced apart. A rotating groove 21 is provided on the inner wall of the receiving cavity. A rotating block 20 corresponding to the rotating groove 21 is provided on the outer side of the sliding column 9 inside the receiving cavity. The rotating block 20 slides inside the rotating groove 21. The outer diameter of the rotating block 20 is smaller than the inner diameter of the rotating groove 21. With this arrangement, the rotating block 20 can slide inside the rotating groove 21 without the rotating block 20 getting stuck inside the rotating groove 21.
[0042] When the transmission bar 6 is running, it also drives the second gear 16. During operation, the second gear 16 meshes with the first toothed plate 17, allowing it to rotate to one side. After rotation, the second gear 16 meshes with the second toothed plate 19, causing it to reverse direction. Following this process, the second gear 16, through its connection with the sliding column 9, drives the sliding column 9 to rotate. As the sliding column 9 rotates, the rotating block 20 slides inside the rotating groove 21, causing the rotating groove 21 to move the sliding column 9 upwards. A slider 2 is provided inside the second gear 16. 3. A groove 22 is provided on the outer side of the sliding column 9 and at the position corresponding to the slider 23. The second gear 16 and the sliding column 9 are slidably connected through the mutual cooperation between the slider 23 and the groove 22. Through the sliding connection between the second gear 16 and the sliding column 9 through the slider 23 and the groove 22, and through the rotational connection between the second gear 16 and the fixed column 8, the second gear 16 will not slide with the sliding column 9, but will only drive the sliding column 9 to rotate. This causes the sliding column 9 to drive the glass to rotate back and forth and move up and down. Through this regular movement, the glass can receive more uniform heat and will not cause uneven heat reception, resulting in a high defect rate.
[0043] Working principle: When using this device to anneal borosilicate glass, the user can first open the opening and closing door 2, and then fit the glass onto the outside of the sliding column 9. Through the spring 10 and the mounting strip 11, the glass can be fitted onto the outside of the mounting strip 11, so that the mounting strip 11 abuts against the glass to prevent the glass from vibrating during annealing. During annealing, the heating block 3 is turned on, so that the heating block 3 emits heat and starts the annealing process. At this time, the motor 7 is started, so that the output end of the motor 7 drives the rotating column 4 to rotate, and then the rotating column 4 drives the transmission strip 6 to rotate, so that the glass can revolve during annealing to ensure that the glass receives a uniform amount of heat.
[0044] When the transmission bar 6 is running, it can drive the fixed column 8 to move, which in turn drives the first gear 15 to move. When the first gear 15 moves, it can mesh with the ring bar 13, so that the first gear 15 can rotate, which in turn drives the fixed column 8 to rotate, thereby driving the glass on the mounting bar 11 to rotate, which makes the heat received by the glass more uniform, thus ensuring the toughness of the glass during annealing.
[0045] After heating is complete, heating block 3 can be turned off, allowing the glass to cool naturally. The glass can then be removed to complete the annealing process.
[0046] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
