Description

Technical Field

[0002] In the field of pharmaceutical packaging, medium-borosilicate pharmaceutical glass has become an ideal material for containing various drugs such as injections and vaccines due to its excellent chemical stability, thermal stability, and good biocompatibility. The annealing process, as a key link in the production of medium-borosilicate pharmaceutical glass, aims to eliminate the internal stress generated during the forming process of the glass and prevent the glass products from cracking or deteriorating in performance during subsequent use. With the continuous improvement of the requirements for the safety and stability of pharmaceutical packaging in the pharmaceutical industry, higher standards have been put forward for the performance of the annealing mechanism for the production of medium-borosilicate pharmaceutical glass.

[0003] Existing annealing mechanisms for the production of medium-borosilicate pharmaceutical glass usually adopt traditional heating and cooling methods. In terms of structure, a fixed flame-spraying device is mostly used to provide heat, the glass bottles are supported by simple brackets, and the movement or rotation of the glass bottles is achieved through manual or mechanical transmission. In terms of hot air circulation, some mechanisms only set a single air inlet and outlet, and rely on natural convection to achieve the flow of hot air in the annealing space.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to the attached Figure 1 - attached Figure 10The embodiment of the present invention provides an annealing mechanism for the production of medium-borosilicate pharmaceutical glass, including a flamethrower assembly 1 and a mounting plate 3. The flamethrower assembly 1 is used as the core heat source for the annealing operation. The flamethrower 101 thereof can achieve flexible angle adjustment through a hanger 102 connected by rotation at the top, so as to adapt to the annealing requirements of glass bottles 2 of different specifications. The energy line 103 is arranged around the outer side of the flamethrower 101, and can efficiently and stably deliver energy to the flamethrower 101, ensuring that the flamethrower 101 continuously and stably sprays flames, and provides sufficient heat for the annealing process of the glass bottle 2. The mounting plate 3 is internally rotatably connected to a plurality of support assemblies 4, and a glass bottle 2 is arranged on the top of the support assembly 4. The support assembly 4 includes a rotating rod 401. During the annealing process, the rotating rod 401 not only plays the role of driving the glass bottle 2 to rotate, but also has a linkage relationship with the hot air guide assembly 5. The top of the rotating rod 401 is fixedly connected with a support rod 402, and two air guide grooves 403 are provided on the outer side of the support rod 402. The air guide grooves 403 cooperate with the nozzle 507 of the hot air guide assembly 5. When the hot air guide assembly 5 is working, the air cylinder 503 delivers hot air to the nozzle 507 through the connecting seat 509 and the air outlet pipe 508 and blows air toward the bottle mouth of the glass bottle 2. The air guide grooves 403 can accurately guide the airflow so that the hot air enters the glass bottle 2 along a predetermined path. Two cavities 404 are provided inside the support rod 402, and two springs 406 are fixedly connected to the inner wall of the cavity 404. One end of the two springs 406 is fixedly connected to a support block 405. When the glass bottle 2 is placed upside down, the outer side of the support block 405 fits the inner wall of the glass bottle 2, and can adjust the position according to the shape of the inner wall of the glass bottle 2, while providing stable support, avoiding hard damage to the glass bottle 2. A sliding hole 407 is provided at the top of the support rod 402, a sliding column 408 is slidably connected inside the sliding hole 407, a connecting column 409 is fixedly connected to the top of the sliding column 408, a spring 2 410 is sleeved on the outside of the connecting column 409, a support seat 411 is fixedly connected to the top of the connecting column 409, and the two ends of the spring 2 410 are respectively fixedly connected to the support seat 411 and the outer side of the support rod 402. When the glass bottle 2 is pressed down by the pressing component 6, the spring 2 410 is compressed to accumulate elastic potential energy; when the pressing state is released, the spring 2 410 releases the elastic potential energy and pushes the glass bottle 2 to move upward. A pressing component 6 is arranged above the glass bottle 2, and a hot air guiding component 5 is arranged outside the mounting plate 3. The hot air guiding component 5 includes a base 501 and an electric telescopic rod 502, and the base 501 provides a stable installation foundation for the air cylinder 503. A spring telescopic rod 510 is slidably connected to the outer through hole of the air cylinder 503, and one end of the spring telescopic rod 510 is fixedly connected to a piston. A cam 511 is fixedly connected to the outer side of one of the rotating rods 401. As the rotating rod 401 rotates, the cam 511 also rotates. When the raised part of the cam 511 contacts the spring telescopic rod 510, the spring telescopic rod 510 is pushed to drive the piston to move in the air cylinder 503.The other end of the air cylinder 503 is fixedly connected to an air inlet pipe 504. The top of the air cylinder 503 is fixedly connected to a connecting seat 509. Check valves are provided at the communication parts of the air inlet pipe 504 and the connecting seat 509 with the air cylinder 503 to ensure that the hot air can only flow unidirectionally, that is, be inhaled into the air cylinder 503 from the air inlet pipe 504 and then discharged from the connecting seat 509. Above the air cylinder 503, there are two L-shaped frames 505. The outer sides of the two L-shaped frames 505 are fixedly connected to an assembly plate 506. A plurality of nozzles 507 are installed on the outer side of the assembly plate 506. One end of the nozzle 507 is fixedly connected to an air outlet pipe 508. One end of the air outlet pipe 508 is fixedly connected to the top of the connecting seat 509, so as to convey the hot air in the air cylinder 503 to the nozzles 507 to blow air against the bottle mouth of the glass bottle 2. At the same time, a cylindrical gear 517 is fixedly connected to the outer side of the support rod 402. The output end of the electric telescopic rod 502 is fixedly connected to a connecting rod 512. One end of the connecting rod 512 is fixedly connected to a rack plate 513. When the electric telescopic rod 502 is started to drive the rack plate 513 to move reciprocally, the rack plate 513 meshes with the cylindrical gear 517, so that the rotating rod 401 can rotate reciprocally. One side of the rack plate 513 meshes with a plurality of cylindrical gears 517. A T-shaped strip 514 is fixedly connected to the outer side of the rack plate 513. Two limiting sleeves 516 are sleeved on the outer side of the T-shaped strip 514. A fixed seat 515 is fixedly connected to the outer side of the limiting sleeve 516 to ensure the stability of the movement of the rack plate 513. The pressing assembly 6 includes an installation table 601. A plurality of round holes 602 inside the installation table 601 provide a guiding channel for the movement of the pressing rod 607. A plurality of blocking rings 603 are fixedly connected to the top of the installation table 601 to limit the maximum height of the upward bounce of the glass bottle 2 and prevent the glass bottle 2 from jumping out of the working area. An assembly frame 604 is arranged on the top of the installation table 601. A plurality of limiting rings 605 are fixedly connected to the inner side of the assembly frame 604 and cooperate with the pressing rod 607 to ensure the stability of the pressing rod 607 during the up and down movement. Above the installation table 601, there is a strip-shaped seat 606. A plurality of pressing rods 607 are fixedly connected to the inside of the strip-shaped seat 606. The outer side of the pressing rod 607 is slidably connected to the inner side of the limiting ring 605. Two assembly frames 613 are fixedly connected to the top of the installation table 601. A first inclined block 608 is rotatably connected to the outer side of the assembly frame 613. Second inclined blocks 609 are fixedly connected to both outer sides of the strip-shaped seat 606. When the strip-shaped seat 606 drives the pressing rod 607 to press down, the second inclined block 609 contacts the first inclined block 608, and the first inclined block 608 rotates against the pulling force of the tension spring 610 under the extrusion of the second inclined block 609; when the second inclined block 609 passes over the first inclined block 608, the first inclined block 608 resets under the pulling force of the tension spring 610, and its tongue plate 612 catches the second inclined block 609 to realize the continuous pressing of the glass bottle 2. A gantry frame 611 is fixedly connected to the top of the assembly frame 613. One end of the tension spring 610 is fixedly connected to the outer side of the gantry frame 611.

[0033] Specifically, first, invert the glass bottle 2 on the top of the support base 411. The support base 411 can adaptively adjust its height and position according to the weight and placement of the glass bottle 2 through the cooperation of the connecting column 409, the sliding column 408 and the second spring 410, providing a stable and elastically buffered placement platform for the glass bottle 2. Such elastic support can not only ensure the stability of the glass bottle 2 during placement, but also avoid damaging the glass bottle 2 due to hard contact, ensuring the integrity of the glass bottle 2 during the subsequent annealing process. Then, the strip-shaped seat 606 drives the pressure rod 607 to press down, so that the outer side of the glass bottle 2 is pressed. At this time, the pressure rod 607 steadily descends along the circular hole 602 inside the mounting table 601, and under the restriction of the limit ring 605, the perpendicularity and stability of the pressing process are ensured. As the pressure rod 607 presses down, the inclined surface of the second inclined surface block 609 will contact and displace the inclined surface of the first inclined surface block 608. The first inclined surface block 608 is reset under the pulling force of the tension spring 610, and then will limit the position of the second inclined surface block 609, so that the glass bottle 2 is in a continuously pressed state. This continuous pressing action can ensure that the glass bottle 2 maintains a fixed position during the annealing process, avoiding shaking or displacement due to factors such as the flame impact of the flame spraying component 1 and the air flow blowing of the hot air guiding component 5, thus ensuring the accuracy and stability of the annealing operation. At this time, the flame spraying component 1 can be started for annealing operation. The spray nozzle 101 continuously and stably sprays flames under the stable energy supply of the energy line 103. Since the spray nozzle 101 can be flexibly adjusted in angle through the suspension bracket 102, it can accurately spray the flames onto the surface of the glass bottle 2 according to the specific specifications of the glass bottle 2 and the annealing requirements, providing uniform and sufficient heat for the glass bottle 2, so that the glass bottle 2 gradually reaches the temperature required for annealing. And start the electric telescopic rod 502 to drive the rack plate 513 to move reciprocally. The precise control of the electric telescopic rod 502 enables the rack plate 513 to move reciprocally according to the predetermined stroke and speed. The rack plate 513 meshes with the cylindrical gear 517, so that the cylindrical gear 517 rotates reciprocally. The cylindrical gear 517 is fixed on the outside of the support rod 402, and then drives the rotating rod 401 and the support rod 402 to rotate reciprocally together. The rotation of the rotating rod 401 drives the glass bottle 2 to rotate on the one hand, so that the outside of the glass bottle 2 is evenly heated, avoiding local overheating or overcooling and improving the annealing quality; on the other hand, the cam 511 fixedly connected to the outside of the rotating rod 401 also rotates accordingly. When the cam 511 rotates, it will push the spring telescopic rod 510 to drive the piston to move. When the convex part of the cam 511 contacts the spring telescopic rod 510, it pushes the spring telescopic rod 510 to move inward, and the piston compresses the air in the air cylinder 503; when the convex part of the cam 511 leaves the spring telescopic rod 510, the spring telescopic rod 510 resets under its own elastic force, and the piston moves outward, forming a negative pressure in the air cylinder 503.Since one-way valves are provided at the connection points of the intake pipe 504 and the connection seat 509 with the air cylinder 503, hot air can only be inhaled into the air cylinder 503 from the intake pipe 504 and discharged from the connection seat 509. The discharged hot air is conveyed through the outlet pipe 508 to the nozzle 507, blowing air against the mouth of the glass bottle 2. At the same time, the air guide groove 403 can assist in guiding the air flow into the interior of the glass bottle 2, enabling the hot air to be evenly distributed inside and outside the glass bottle 2, thereby ensuring that the internal and external temperatures of the glass bottle 2 are balanced during annealing, effectively reducing the internal stress generated due to temperature differences, and improving the annealing effect and quality of the glass bottle 2. Throughout the process, the elastic support function of the support block 405 and the support seat 411 always plays an important role. Under the action of the first spring 406, the support block 405 closely fits the inner wall of the glass bottle 2, providing stable internal support for the glass bottle 2; through the elastic buffering of the second spring 410, the support seat 411 ensures its stable position when the glass bottle 2 rotates and is subjected to external forces, and at the same time does not cause damage to the glass bottle 2. In addition, when it is necessary to perform a ventilation operation on the glass bottle 2 to further achieve more balanced annealing temperature, the tongue plate 612 can be toggled to release the restriction on the second inclined surface block 609. At this time, under the elastic force of the second spring 410, the glass bottle 2 will bounce upward for a certain distance and then be blocked by the blocking ring 603. During the bouncing process, the hot air inside the glass bottle 2 will exchange with the cold air outside, being able to inhale the external air into the interior of the glass bottle 2 for ventilation, thereby taking away part of the heat inside the glass bottle 2, reducing the internal temperature, achieving more balanced annealing temperature, and further improving the annealing quality of the glass bottle 2.

[0034] Working principle: First, invert the glass bottle 2 on the top of the support seat 411. The strip seat 606 drives the pressure lever 607 to press down so that the outer side of the glass bottle 2 is pressed. At this time, the inclined surface of the second inclined surface block 609 will contact and displace the inclined surface of the first inclined surface block 608. The first inclined surface block 608 is reset under the pulling force of the tension spring 610, and then the position of the second inclined surface block 609 will be restricted, so that the glass bottle 2 is in a continuously pressed state. At this time, the annealing operation can be started by activating the flame spraying assembly 1, and the electric telescopic rod 502 is activated to drive the rack plate 513 to reciprocate, so that the cylindrical gear 517 rotates reciprocally, and then the cam 511 rotates and pushes the spring telescopic rod 510 to drive the piston to move. In this way, hot air can be inhaled into the interior of the air cylinder 503 and discharged from the connecting seat 509 and conveyed to the nozzle 507 to blow air at the mouth of the glass bottle 2. And the air guide groove 403 can assist in guiding the air flow into the interior of the glass bottle 2, so as to ensure that the internal and external temperatures of the glass bottle 2 are balanced during annealing. And under the elastic support of the support block 405 and the support seat 411, in addition to ensuring the stable position of the glass bottle 2, it will not cause damage to the glass bottle 2. At the same time, it can drive the glass bottle 2 to rotate, which can ensure that the outside of the glass bottle 2 is evenly heated. And the tongue plate 612 can be toggled to release the restriction on the second inclined surface block 609. In this way, under the elastic force of the second spring 410, the glass bottle 2 will bounce upward for a certain distance and then be blocked by the blocking ring 603. When bouncing, external air can be inhaled into the interior of the glass bottle 2 for air exchange, so as to make the annealing temperature more balanced.
