Description

Technical Field

[0001] This utility model relates to the field of glass neck thickening technology, and more specifically, to a device for thickening the neck of a borosilicate glass ampoule. Background Technology

[0002] In the production and processing of borosilicate glass ampoules, the neck thickening device is a key piece of equipment for ensuring the structural integrity of the ampoule and improving the product qualification rate. Its performance in achieving precise neck ring fixation and effectively avoiding the risk of bottleneck cracking due to high temperature is crucial. However, existing borosilicate glass ampoule neck processing devices still have prominent problems that restrict processing safety in practical applications.

[0003] Most existing related devices lack a synchronous linkage control mechanism for heating and cooling. The neck of the borosilicate glass ampoule is relatively thin, and excessive heating or untimely cooling can cause the neck to crack due to heat. In addition, the molding part lacks an anti-adhesion structure, and the plastic ring will stick to the molding part after heating, resulting in an uneven surface of the molded plastic ring. To solve the above problems, there is an urgent need for a neck thickening device for borosilicate glass ampoules that prevents cracking and adhesion. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for thickening the neck of borosilicate glass ampoules to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a borosilicate glass ampoule neck thickening device, comprising a base plate, an electric slide rail fixedly mounted on the top of the base plate, a limiting block welded to one side of the electric slide rail, a slider slidably connected to the electric slide rail on the top of the limiting block, a thickening component fixedly mounted on one side of the slider, and an ampoule bottle disposed inside the thickening component.

[0006] As a further description of the above technical solution: the thickened component includes a fixing ring fixedly connected to one side of the slider, and a plurality of hot air guns are fixedly provided at the bottom of the fixing ring, and the plurality of hot air guns are distributed in a ring array at the bottom of the fixing ring.

[0007] As a further description of the above technical solution: an adjustment frame is fixedly provided on one side of the slider, and slide rails are provided at the top and bottom of the adjustment frame, with two vertical plates sliding between the two slide rails.

[0008] As a further description of the above technical solution: an electric telescopic rod is hinged between the two vertical plates, and a spring is provided on the outside of the electric telescopic rod, with both ends of the spring fixedly connected to the vertical plate.

[0009] As a further description of the above technical solution: a limiting plate is fixedly provided on one side of each of the two vertical plates, a shaping ring is provided on the top of the limiting plate, and the cross-section of the limiting plate is set as a semi-circular arc.

[0010] As a further description of the above technical solution: the top of the shaping ring is provided with a gas outlet hole, and two grooves are provided on the inner side of the shaping ring. An annular gas ring is fixedly provided on the inner side of each of the two grooves. The annular gas ring is provided with multiple micron-sized gas outlet holes and contains nitrogen gas.

[0011] As a further description of the above technical solution: the shaping ring has a plastic ring inside, the plastic ring has an ampoule inside, the bottom of the ampoule is connected to a factory fixture, and the surface of the shaping ring is coated with a ceramic composite coating.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a thickened component, a plastic ring is fitted onto the neck of the ampoule. An electric telescopic rod drives two vertical plates to slide synchronously, causing two limiting plates to clamp the shaping ring. A hot air gun is turned on to blow hot air, using the heat to heat the plastic ring to adhere to the surface of the ampoule neck and the inside of the shaping ring. The heat insulation properties of nitrogen inside the annular gas ring are used to slowly cool the heated plastic ring. Compared with the existing technology, the electric telescopic rod drives the limiting plates to clamp the shaping ring, making the shaping ring and the plastic ring fit more tightly, creating a stable shaping system. The local slow cooling of nitrogen can avoid bottle cracking caused by excessive neck contraction, reduce the risk of neck explosion, and greatly improve the safety of the thickened ampoule neck molding.

[0014] 2. By setting a shaping ring and an annular gas ring, the ampoule is rotated axially using factory fixtures. Nitrogen gas is introduced through the gas inlet at the top of the shaping ring. The thermal insulation of the nitrogen gas inside the annular gas ring is used to slowly cool the heated plastic ring through micron-sized gas outlets. Compared with existing technologies, by using a shaping ring in conjunction with an annular gas ring, the low thermal conductivity of nitrogen gas is used to output a stable airflow to the surface of the heated plastic ring, achieving a gradient and slow cooling. This avoids internal stress caused by excessive temperature difference in the glass neck, inhibits excessive shrinkage and crack initiation. The nitrogen gas flow forms an inert gas cushion layer between the plastic ring and the shaping ring, solving the adhesion problem under high temperature conditions. While slowly cooling, the centrifugal force generated by rotation and the synergistic effect of nitrogen gas flow quickly remove debris and surface impurities generated during the heating and shaping of the plastic ring, preventing impurities from embedding in the thickened layer or adhering to the glass surface. This ensures the cleanliness and aesthetic appearance of the ampoule neck and improves the pass rate of neck thickening molding. Attached Figure Description

[0021] 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.

[0022] As attached Figure 1-5 The borosilicate glass ampoule neck thickening device shown includes a base plate 1, an electric slide rail 2 fixedly mounted on the top of the base plate 1, a limiting block 3 welded to one side of the electric slide rail 2, a slider 4 slidably connected to the electric slide rail 2 on the top of the limiting block 3, a thickening component fixedly mounted on one side of the slider 4, and an ampoule bottle 5 inside the thickening component.

[0023] In some embodiments, according to Figure 2-3 As shown, the thickened component includes a fixing ring 6 fixedly connected to one side of the slider 4. Multiple hot air guns 7 are fixedly provided at the bottom of the fixing ring 6. The multiple hot air guns 7 are distributed in a ring array at the bottom of the fixing ring 6. The hot air guns 7 heat the ampoule neck and plastic ring 16 evenly to ensure that the plastic ring 16 is fully softened. The full-coverage heating range design avoids uneven adhesion caused by local temperature differences.

[0024] In some embodiments, according to Figure 1-4 As shown, an adjustment frame 8 is fixedly provided on one side of the slider 4. The top and bottom of the adjustment frame 8 are provided with slide rails 9, and two vertical plates 10 are slidably provided between the two slide rails 9.

[0025] In some embodiments, according to Figure 3-5As shown, an electric telescopic rod 11 is hinged between the two vertical plates 10. A spring 12 is provided on the outside of the electric telescopic rod 11. Both ends of the spring 12 are fixedly connected to the vertical plate 10. The spring 12 buffers and protects the molding ring 14 to avoid deformation of the molding ring 14 due to excessive compression.

[0026] In some embodiments, according to Figure 3-5 As shown, each of the two vertical plates 10 is fixed with a limiting plate 13 on one side. The top of the limiting plate 13 is provided with a shaping ring 14. The cross-section of the limiting plate 13 is set as a semi-circular arc. The arc structure is precisely fitted to the outside of the shaping ring 14 to ensure that the shaping ring 14 is coaxially positioned.

[0027] In some embodiments, according to Figure 5 As shown, the top of the molding ring 14 has an air outlet, and two grooves are formed on the inner side of the molding ring 14. An annular gas ring 15 is fixedly provided on the inner side of each groove. The annular gas ring 15 has multiple micron-sized air outlets inside and contains nitrogen gas. The annular gas ring 15 has several micron-sized air outlets evenly distributed along the circumference of the molding ring. The air outlets face the neck area of ​​the ampoule to be cooled and are inclined at a 30° angle to ensure that the nitrogen gas flow fits the curved surface of the neck to form a uniform air curtain and avoid stress concentration caused by strong cooling at a single point.

[0028] In some embodiments, according to Figure 1 As shown, the shaping ring 14 has a plastic ring 16 inside, and the ampoule 5 is inside the plastic ring 16. The bottom of the ampoule 5 is connected to the factory fixture. The surface of the shaping ring 14 is coated with a ceramic composite coating to adapt to the high-temperature environment of hot air heating and reduce the adhesion of the plastic ring 16.

[0029] The working principle of this utility model is as follows: First, the bottom of the ampoule 5 is fixed to the factory-specific clamp. The worker then places the plastic ring 16 around the neck of the ampoule 5. When the ampoule 5 moves directly below the thickening device, the electric slide rail 2 is activated. The slider 4 drives the entire thickening assembly vertically downwards to the top of the limiting plate 13. At this time, the electric telescopic rod 11 is activated. The telescopic rod's extension and retraction cause the two vertical plates 10 to slide synchronously along the slide rail 9 of the adjusting frame 8, thereby adjusting the clamping force of the two limiting plates 13. This ensures that the shaping ring 14 applies uniform pressure to the plastic ring 16 and the neck of the ampoule 5. Simultaneously, the spring 12 acts as a buffer, preventing excessive pressure from damaging the neck of the ampoule 5. Then, the hot air gun 7 is turned on. The hot air guns 7, arranged in a ring array at the bottom of the fixing ring 6, blow hot air onto the plastic ring 16, causing the plastic ring to... The material ring 16 is heated and adheres to the neck surface of the ampoule 5 and the inner side of the shaping ring 14. The bottom of the limiting plate 13 can wrap around the bottom of the plastic ring 16 to achieve bottom shaping and adhesion of the plastic ring 16. After heating and shaping, the hot air gun 7 is turned off. The ampoule 5 is rotated axially using the factory fixture. Nitrogen gas is introduced into the gas outlet at the top of the shaping ring 14. The heat insulation property of the nitrogen gas inside the annular gas ring 15 is used to slowly cool the heated plastic ring 16 through the micron-level gas outlet. The nitrogen gas flow forms an inert gas cushion layer between the plastic ring and the shaping ring, solving the adhesion problem under high temperature environment. At the same time, the rotation of the bottle causes the gas flow to carry away plastic debris on the surface, avoiding the adhesion of impurities during the cooling process. The drying property of nitrogen gas can also prevent the glass neck surface from cracking due to moisture and shattering. This completes the entire process of using the borosilicate glass ampoule neck thickening device.
