Description

Technical Field

[0001] This invention relates to the field of glass bottle production and processing technology, specifically to an annealing device for perfume glass bottles that utilizes waste heat. Background Technology

[0002] Annealing is an indispensable and crucial process in the production of perfume glass bottles. Its core function is to eliminate internal stress in the glass, preventing breakage and deformation during subsequent processing, storage, or use. Therefore, the performance of the annealing equipment directly affects the product quality of perfume glass bottles and the production efficiency of enterprises. Currently, the annealing equipment used in the industry for perfume glass bottles generally uses conveyor belts and pallets to transport and anneal the bottles, and lacks effective measures for recovering and utilizing the high-temperature waste heat generated during the annealing process. The two most obvious drawbacks are: first, poor annealing uniformity. The pallets in existing equipment are mostly solid structures without ventilation, and the contact method between the bottle and the pallet is unreasonable, resulting in the annealing airflow not being able to act on the bottle surface in all directions. This leads to inconsistent temperature changes in different parts of the bottle, often resulting in localized high and low annealing temperatures, which in turn affects the annealing effect and reduces the product qualification rate; second, high energy consumption. Existing equipment cannot make reasonable use of the high-temperature waste heat generated during the annealing process. In order to maintain the temperature gradient required for annealing—high temperature at the inlet and low temperature at the outlet—an additional heating device needs to be added at the rear of the equipment, which not only wastes a lot of energy but also increases the production costs of enterprises. In view of the above-mentioned shortcomings of existing annealing equipment, there is an urgent need for a waste heat annealing device for perfume glass bottles that can solve the problems of poor annealing uniformity and high energy consumption.

The design of the synchronization rod and guide holes ensures smooth operation, while high-temperature resistant springs and other components are suitable for high-temperature environments, reducing wear and tear. Modular snap-fit ​​connections and simple maintenance processes reduce subsequent costs. Furthermore, its strong adaptability to different bottle sizes and high safety of closed operation together constitute its high practicality and economy. Attached Figure Description

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] Please see Figure 1 , Figure 2 and Figure 3 An annealing device for perfume glass bottles utilizing waste heat includes an annealing furnace 1. The left end of the annealing furnace 1 is an inlet for feeding perfume glass bottles to be annealed into the device, and the right end is an outlet for discharging the annealed bottles. Multiple air outlet pipes 11 are evenly distributed along a straight line at the upper end of the annealing furnace 1. This even distribution ensures uniform airflow extraction within the annealing furnace 1, avoiding temperature imbalance caused by localized airflow turbulence. A collecting pipe 12 is connected to each air outlet pipe 11, which collects the high-temperature airflow extracted from the multiple outlet pipes 11 for subsequent unified utilization. A fan 13 is connected to the end of the collecting pipe 12 near the outlet. The fan 13, located at the outlet end, creates a large negative pressure at the outlet, thereby allowing... The air velocity in the exhaust pipe 11 gradually increases from the inlet to the outlet, perfectly matching the temperature gradient requirements of the annealing furnace 1, which has a high temperature at the inlet and a low temperature at the outlet. This effectively solves the problems of insufficient waste heat utilization and the need for additional heating devices at the rear end in existing devices. The annealing furnace 1 is equipped with a conveying device 2, which is used to stably transport perfume glass bottles to be annealed and those that have already been annealed. The conveying device 2 is equipped with multiple receiving components 3, which are used to directly support the perfume glass bottles, ensuring that the bottles will not tip over or shift during transport and annealing. The conveying device 2 is also equipped with several lifting components 4 that correspond one-to-one with the receiving components 3. The lifting components 4 can drive the movement of part of the structure of the receiving components 3, realizing alternating contact between the bottles and the receiving structure, further improving the uniformity of annealing.

[0020] Please see Figure 1 and Figure 2 The conveying device 2 includes a conveyor frame 21, which serves as the installation foundation for the conveying device 2, providing stable support for each component and ensuring that the entire conveying structure does not shake during operation. Two sets of synchronously rotating sprockets 24 are respectively installed at the left and right ends of the conveyor frame 21. The synchronous rotation of the two sets of sprockets 24 ensures that the movement speed of the two annular chains 25 is consistent, preventing the receiving component 3 from shifting or tilting during conveying. Two annular chains 25 are connected to the sprockets 24. The two chains 25 are symmetrically arranged, which makes the force on the receiving component 3 more uniform and improves the stability of the conveying process. The two ends of the receiving component 3 are rotatably connected to the chains 25. This connection method reduces frictional loss between the receiving component 3 and the chains 25, extends the service life of the components, and facilitates the smooth movement of the receiving component 3 with the chains 25. The lifting component 4 is rotatably connected to the conveyor frame 21, ensuring that the lifting component 4 can rotate flexibly, achieving precise lifting and resetting of the receiving component 3, thus solving the problems of unstable operation and rapid component wear in existing conveying devices. The conveyor frame 21 is equipped with a reducer 22 and a motor 23. The motor 23 provides power to the entire conveying device 2, and the power output is stable and controllable. The conveying speed can be adjusted according to the annealing requirements. The input end of the reducer 22 is driven to the output end of the motor 23. The reducer 22 can convert the high speed output by the motor 23 into a low speed suitable for conveying, while increasing the output torque to ensure the smooth operation of the sprocket 24 and chain 25, and avoid the bottles tipping over and insufficient annealing due to excessive speed. The output end of the reducer 22 is driven to the sprocket 24 to achieve precise power transmission, which solves the problems of unstable power transmission and uncontrollable conveying speed in existing conveying devices, ensuring that the bottles have sufficient annealing time in the annealing furnace channel 1 and improving the annealing quality.

[0021] Please see Figure 3 , Figure 4 and Figure 5The receiving component 3 includes a fixing plate 31, which serves as the mounting carrier for the receiving component 3. The fixing plate 31 is used to fix the fixed receiving component 33 and support the movable receiving component 34, ensuring the overall stability of the receiving component 3. Connecting components 32 are fixed to the front and rear ends of the fixing plate 31, respectively. The connecting components 32 connect the fixing plate 31 to the chain 25. The left and right ends of the connecting components 32 are rotatably connected to the chain 25, ensuring that the fixing plate 31 moves smoothly with the chain 25, while reducing the friction between the connecting components 32 and the chain. To mitigate wear between 25, multiple fixed support members 33 are fixed on the fixed plate 31. These fixed support members 33 are evenly distributed and can stably support the perfume glass bottle, preventing the bottle from shaking during transportation. Each pair of fixed support members 33 is slidably connected to a movable support member 34. The movable support member 34 can slide relative to the fixed support member 33, achieving alternating support with the fixed support member 33. This solves the problems of the existing single support structure and uneven local annealing of the bottle, ensuring that all parts of the bottle can fully contact the airflow and improving the uniformity of annealing.

[0022] Please see Figure 3 , Figure 4 and Figure 5 The fixed receiving member 33 has two inclined guide holes 331, which guide the sliding of the movable receiving member 34, ensuring that the movable receiving member 34 will not deviate or jam during lifting and lowering. An inclined insertion hole 332 is provided between the two guide holes 331. The insertion hole 332 is located on the fixed receiving member 33, and the guide holes 331 and insertion hole 332 are parallel. This parallel design ensures that the guide post 341 of the movable receiving member 34 slides synchronously, guaranteeing a smooth and non-tilting lifting and lowering process for the movable receiving member 34. A groove 333 is provided inside the insertion hole 332 for installing a high-temperature resistant spring 334 and a sliding member 335, providing a return mechanism for the movable receiving member 34. Provided with installation space, a high-temperature resistant spring 334 is installed inside the insertion hole 332. The high-temperature resistant spring 334 can maintain its elasticity under high-temperature annealing environment, ensuring that the moving bearing 34 can be stably reset. This solves the problem that ordinary springs are prone to failure under high-temperature environment and the moving bearing 34 cannot be reset. The high-temperature resistant spring 334 is placed in the groove 333. A sliding member 335 is slidably connected in the groove 333. The sliding member 335 can slide flexibly in the groove 333. The sliding member 335 is connected to the high-temperature resistant spring 334. The elastic force of the high-temperature resistant spring 334 is transmitted to the moving bearing 34 through the sliding member 335, realizing the automatic reset of the moving bearing 34 and ensuring the continuous and stable alternating bearing process.

[0023] Please see Figure 3 , Figure 4 and Figure 5The movable receiving member 34 is provided with guide posts 341 corresponding to the guide hole 331 and the insertion hole 332. The guide posts 341 are inserted into the guide hole 331 and the insertion hole 332 respectively, and cooperate with the guide hole 331 and the insertion hole 332 to realize the precise sliding of the movable receiving member 34, avoid the movable receiving member 34 from deviating during sliding, and ensure that the movable receiving member 34 can accurately contact the bottle. The height of the upper end face of the movable receiving member 34 is lower than the height of the upper end face of the fixed receiving member 33. This height design can ensure that the bottle can be stably placed on the fixed receiving member 33 in the initial state, avoid the movable receiving member 34 interfering with the placement of the bottle in the initial state, and at the same time reserve space for the upward receiving of the movable receiving member 34, ensuring a smooth alternating receiving process, and solving the problem of unreasonable initial position of the movable receiving member 34 interfering with the placement of the bottle.

[0024] Please see Figure 3 , Figure 4 and Figure 5 The fixed receiving member 33 and the movable receiving member 34 are L-shaped. The L-shaped structure can limit the perfume glass bottle, effectively preventing the bottle from sliding backward during transportation. This solves the problems of existing receiving structures having no limit and bottles easily shifting and falling, improving the stability of the transportation process. The upper surfaces of the fixed receiving member 33 and the movable receiving member 34 are chamfered. The chamfering treatment allows the fixed receiving member 33 and the movable receiving member 34 to form line contact with the bottle. Compared with surface contact, line contact can reduce the obstruction of the bottle surface and ensure that the bottle surface can fully contact the airflow. To avoid the phenomenon of local areas not being able to be annealed, the fixed support 33 and the movable support 34 are hollow inside and have openings at their lower ends. The hollow structure and the openings at the lower ends allow the airflow flowing from bottom to top in the annealing furnace channel 1 to smoothly enter the fixed support 33 and the movable support 34. The beveled surfaces of the fixed support 33 and the movable support 34 are respectively provided with holes, and the airflow can be blown directly onto the surface of the bottle through these holes to achieve all-round annealing of the bottle. This completely solves the problems of poor ventilation of existing pallets, uneven local annealing of bottles, and local high or low temperatures.

[0025] Please see Figure 3 and Figure 6The lifting assembly 4 includes two lifting arms symmetrically arranged to ensure uniform lifting force on the movable support 34 and prevent tilting of the movable support 34 during lifting. Each lifting arm includes two swing rods 41, which are the core force-bearing components of the lifting arm and can rotate to raise or lower the lifting plate 44. A synchronizing rod 43 is connected to the upper end of each swing rod 41, enabling synchronous rotation of the two swing rods 41. This ensures consistent movement of the two lifting arms, preventing offset or jamming of the movable support 34 due to unilateral lifting, and solving the problems of asynchronous movement of the two lifting arms and unbalanced lifting of the movable support 34. Connecting holes 42 are provided on the two swing rods 41, and the synchronizing rod 43 connects to the conveyor. The frame 21 is rotatably connected, and the connecting hole 42 provides a fulcrum for the rotation of the swing rod 41, ensuring that the swing rod 41 rotates flexibly and smoothly, reducing frictional loss during rotation. The lower ends of the two swing rods 41 are connected to the lifting plates 44, which are used to directly lift the moving support 34, realizing the lifting and lowering of the moving support 34. Multiple lifting plates 44 are arranged between the two lifting arms. The multiple lifting plates 44 are evenly distributed, which can ensure that the moving support 34 is subjected to uniform force and improve the stability of the lifting and lowering of the moving support 34. Air concentrators 45 are arranged between each pair of lifting plates 44. The air concentrators 45 can concentrate and guide the airflow to the lifting plates 44, and then send it into the interior of the moving support 34 through the lifting plates 44, improving the airflow utilization rate and enhancing the annealing effect.

[0026] Please see Figure 6 The lifting plate 44 is provided with a through hole 441 extending vertically, allowing airflow to pass smoothly through the lifting plate 44 and enter the interior of the moving support member 34. A through air inlet 442 is provided on the side of the lifting plate 44, which receives airflow guided by the air collector 45. The air collector 45 is hollow inside and has a connecting port at its lower end. The hollow structure and the connecting port at the lower end allow airflow from the annealing kiln passage 1 to smoothly enter the air collector 45, achieving concentrated airflow collection. A through connecting port 451 is provided on the side of the air collector 45, which connects to the air inlet. The corresponding port 442 ensures that the airflow in the concentrator 45 can accurately enter the air inlet 442 of the support plate 44, avoiding airflow leakage and improving airflow utilization. The connecting port 451 is surrounded by a protruding edge 452. The concentrator 45 is snapped into the air inlet 442 of the support plate 44 through the protruding edge 452. The snap-fit ​​connection facilitates the installation, disassembly and maintenance of the concentrator 45. At the same time, it can ensure that the concentrator 45 is tightly connected to the support plate 44, avoiding airflow leakage from the connection. This solves the problems of low airflow utilization and inconvenient installation and maintenance of components, and further enhances the annealing effect of the moving support 34 on the bottle.

[0027] Please see Figure 3The fixed support members 33 fixed at both ends of the fixed plate 31 correspond to the swing rod 41 and are on the same plane. This correspondence ensures that when the fixed support member 33 moves to the position of the lifting component 4, it can accurately squeeze the swing rod 41 and trigger the lifting component 4 to move, avoiding misalignment that would cause the lifting component 4 to malfunction. The lifting plate 44 corresponds to the moving support member 34 and is on the same plane, ensuring that the lifting plate 44 can accurately lift the moving support member 34 when it rises, achieving a smooth alternation between the moving support member 34 and the fixed support member 33, and avoiding misalignment that would damage the moving support member 34 or cause the bottle to tip over.

[0028] In summary, the various structures work together to achieve multiple core effects: First, by coordinating the air outlet pipe 11, the collecting pipe 12, and the fan 13, the high-temperature waste heat at the feed inlet of the annealing furnace channel 1 is utilized to create a temperature gradient that gradually decreases from the feed inlet to the discharge outlet within the furnace channel. This eliminates the need for additional heating devices at the rear end of the furnace channel, significantly reducing energy consumption and solving the problems of insufficient waste heat utilization and high energy consumption in existing devices. Second, the alternating connection of the fixed receiving component 33 and the moving receiving component 34, combined with their L-shaped structure, chamfered design, and hollow opening structure, ensures that the airflow is directed towards the bottles from all directions, completely solving the problems of uneven annealing and abnormal local temperatures in existing devices, thus improving annealing quality. Third, the coordinated operation of the various components of the conveying device 2 ensures stable bottle transport, and the lifting component 4 moves the bottles up and down, further improving annealing uniformity. Fourth, the precise design of each component ensures smooth and stable operation of the entire device, reduces component wear, extends the device's service life, and facilitates later maintenance, improving the device's practicality and economy.

[0029] When using this invention: Before use, check the status of each component of the device to ensure that there are no foreign objects inside the annealing furnace duct 1, that the chain 25 and sprocket 24 of the conveying device 2 are properly engaged, that the swing rod 41 of the lifting assembly 4 rotates flexibly, that the fixed bearing 33 and the moving bearing 34 slide smoothly, that the high-temperature spring 334 is not deformed or ineffective, and that the air concentrator 45 and the lifting plate 44 are tightly connected without loosening. Then start the blower 13 and motor 23, and adjust the conveying speed by using the motor 23 in conjunction with the reducer 22. Adjust the conveying speed to a suitable range according to the specifications of the perfume glass bottles and the requirements of the annealing process to ensure that the bottles have sufficient annealing time. At the same time, observe the operating status of the blower 13 to ensure that the wind speed in the air outlet pipe 11 increases gradually from the feed port end to the discharge port end, and a stable temperature gradient is formed in the annealing furnace duct 1 with a high temperature at the feed port end and a low temperature at the discharge port end. There is no need to start the rear heating device, and the high temperature residual heat at the feed port end can be fully utilized. After the device parameters have been adjusted and stabilized and the temperature gradient has been established, feeding begins. The perfume glass bottles to be annealed are placed stably on the receiving component 3 at the feed inlet end of the annealing furnace channel 1, specifically on the chamfered end face of the fixed receiving component 33. Because the fixed receiving component 33 has an L-shaped structure, it can limit the bottle's movement, preventing it from sliding backward during placement. Simultaneously, the upper end face of the fixed receiving component 33 is chamfered, forming line contact with the bottle. Its interior is hollow, with an opening at the bottom and holes on the chamfered bevel. At this point, the upward-flowing airflow within the annealing furnace channel 1 can smoothly enter the fixed receiving component 33 and then be blown onto the bottle surface through the holes on the chamfered bevel, initially achieving uniform preheating of the bottle surface and laying the foundation for subsequent annealing. During placement, ensure the bottles are neatly arranged, not tilted, and not stacked to avoid affecting the annealing effect and conveying stability. After feeding is completed, the motor 23 drives the sprocket 24 to rotate synchronously through the reducer 22. The sprocket 24 drives the two ring chains 25 to run smoothly. The chains 25 drive the fixed plate 31 and the fixed support 33, the moving support 34 and the bottle above it through the connector 32 to move along the annealing kiln channel 1 from the feed port end to the discharge port end, and the bottle enters the annealing area. When the fixed support member 33, which is fixed at both ends of the fixed plate 31, moves to the position of the lifting assembly 4, the fixed support member 33 will precisely squeeze the swing rod 41 of the lifting assembly 4, since the two are on the same plane and correspond to each other; under the action of the synchronizing rod 43, the two swing rods 41 rotate synchronously around the connecting hole 42, and the lower end of the swing rod 41 drives the lifting plate 44 and the wind concentrator 45 to rise synchronously; since the lifting plate 44 corresponds to the moving support member 34 and is on the same plane, when the lifting plate 44 rises, it will precisely lift the moving support member 34, and the moving support member 34 will slide smoothly along the guide hole 331 and the insertion hole 332 of the fixed support member 33 through the guide post 341 until the upper end surface of the moving support member 34 protrudes from the upper end surface of the fixed support member 33. At this time, the bottle is separated from the fixed support member 33 and comes into contact with the moving support member 34. The moving receiving part 34 also has an L-shaped chamfered structure, is hollow inside and has openings. At the same time, the airflow in the annealing furnace channel 1 is drawn in through the connecting port at the lower end of the air concentrator 45. After the airflow is concentrated inside the air concentrator 45, it enters the air inlet 442 of the support plate 44 through the connecting port 451 on the side, and then enters the interior of the moving receiving part 34 through the through hole 441 on the support plate 44. Finally, it is blown onto the bottle surface from the hole on its chamfered slope, realizing all-round annealing after the bottle comes into contact with the moving receiving part 34. At the same time, the blower 13 continuously draws high-temperature airflow in the furnace channel through the air outlet pipe 11 and the collecting pipe 12 to realize the recovery and utilization of waste heat, ensure the stability of the temperature gradient in the furnace channel, and the temperature of the bottle gradually decreases during the movement, meeting the requirements of the annealing process. As the receiving component 3 continues to move with the chain 25, after the fixed receiving component 33 is released from the pressure on the swing rod 41, the lifting plate 44 and the air-gathering component 45 return to their original position under their own gravity, and the swing rod 41 rotates in the opposite direction synchronously. At the same time, the high-temperature resistant spring 334 inside the fixed receiving component 33 releases its elastic force, pushing the sliding component 335 to slide along the groove 333. The sliding component 335 drives the moving receiving component 34 to slide down and return to its original position along the guide hole 331 and the insertion hole 332. The upper end face of the moving receiving component 34 falls back to below the upper end face of the fixed receiving component 33, and the bottle is placed back on the fixed receiving component 33 to continue annealing through the airflow through the opening of the fixed receiving component 33. Since the conveying device 2 is equipped with several lifting components 4 corresponding to the receiving component 3, the receiving component 3 will trigger the lifting component 4 multiple times during the process of moving from the inlet end to the outlet end, so as to realize the repeated alternation of the fixed receiving component 33 and the moving receiving component 34. At the same time, the bottle moves slightly up and down with the receiving component 3, which completely avoids the problem of uneven local annealing of the bottle, ensures that the temperature change of each part of the bottle is consistent, and improves the annealing quality. When the receiving component 3 carries the bottle to the discharge port of the annealing furnace channel 1, the bottle has completed all annealing processes and the temperature has dropped to a suitable range. At this time, the operator will carefully remove the annealed perfume glass bottle from the fixed receiving component 33 for subsequent inspection, packaging and other processes, ensuring that the handling process is gentle and avoids collisions that could damage the bottle. At the same time, bottles to be annealed can be continuously added to the feed port according to production needs, realizing continuous operation of the equipment. After production is completed, feeding into the inlet is stopped. Once all remaining bottles in the annealing furnace channel 1 have been conveyed to the outlet and collected, the blower 13 and motor 23 continue to run to cool the inside of the furnace channel and clean debris and dust carried out by the airflow. Then, the blower 13 and motor 23 are shut down, and the wear of each component is checked. Lubricating oil is added to the chain 25, loose connections are tightened, and the failed high-temperature spring 334 or air-concentrating component 45 is replaced to ensure stable operation of the device the next time it is used.
