Description

Technical Field

[0001] This invention relates to the field of glass bottle production technology, specifically to a heat treatment device for glass bottles with a low defect rate. Background Technology

[0002] Glass is a non-crystalline inorganic material that melts, cools, and solidifies. It possesses valuable properties, including transparency, hardness, and excellent corrosion and heat resistance. It can be manufactured into various shapes and sizes using a variety of forming and processing methods, such as the most common glass bottles. In the production of glass bottles, heat treatment is a crucial step that directly affects the quality and lifespan of the final product. Annealing furnaces are key equipment in the heat treatment process. Currently, the most common glass bottle annealing devices on the market are mainly divided into two categories: electric heating and oil-fired heating. Electric heating annealing furnaces are more widely used in small and medium-sized production enterprises due to their ease of control, while oil-fired heating furnaces are more common in large enterprises, providing greater heating power and suitable for mass production of glass products.

[0003] In existing electrically heated annealing furnaces, the internal heating wires are mostly distributed at the bottom and sides of the furnace body. Due to the large number of glass bottles placed inside the annealing furnace, the glass bottles in the central area are far from the heating source, which easily causes uneven heating and damages the glass bottles, resulting in a high defect rate. In addition, the furnace relies heavily on manual feeding, which has low feeding efficiency and affects the annealing efficiency of the glass bottles.

[0004] Therefore, it is necessary to invent a heat treatment device for glass bottles with a low defect rate to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a heat treatment device for glass bottles with a low defect rate, in order to solve the problems of uneven heating, which leads to a high defect rate of glass bottles, and the reliance on manual feeding, which results in low feeding efficiency and affects the annealing efficiency of glass bottles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-rejection-rate glass bottle heat treatment equipment, comprising a first equipment frame, an annealing furnace mounted on the upper side of the first equipment frame, the annealing furnace comprising a furnace body and an insulation plate, a longitudinal partition plate fixedly connected to the inner side of the furnace body, and second heating plates fixedly mounted on the left and right sides of the partition plate and the left and right sides of the inner walls of the furnace body, a third equipment frame and a second equipment frame respectively mounted on the front and rear sides of the first equipment frame, a first conveyor net, a second conveyor net and a third conveyor net respectively mounted on the inner sides of the first equipment frame, the second equipment frame and the third equipment frame, and an automatic feeding component mounted on the upper side of the first equipment frame at the front end of the annealing furnace.

A threaded sleeve is threadedly connected to the surface of the threaded rod. The lower end of the threaded sleeve passes through the central positioning groove and is fixedly connected to the mounting plate.

[0015] By adopting the above technical solution, the second motor is used to drive the threaded rod to rotate, which in turn drives the threaded sleeve to slide left and right, thereby adjusting the left and right position of the mounting plate.

[0018] By adopting the above technical solution, the mounting plate on the lower side of the first slide adjusts the left and right position of the second slide during the sliding process, thereby adjusting the position of the lifting cylinder and the pneumatic gripper to the left and right. During the sliding process, the mounting plate on the lower side of the second slide adjusts the position of the lifting cylinder and the pneumatic gripper to the front and back, which facilitates the placement of the glass bottle.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Example

[0029] This invention provides, for example Figures 1 to 5 The heat treatment equipment for glass bottles with a low defect rate shown includes a first equipment frame 1. An annealing furnace 2 is installed on the upper side of the first equipment frame 1. The annealing furnace 2 includes a furnace body 21 and an insulation plate 22. A longitudinal partition plate 23 is fixedly connected to the inner side of the furnace body 21. Second heating plates 24 are fixedly installed on the left and right surfaces of the partition plate 23 and the left and right inner walls of the furnace body 21. A third equipment frame 5 and a second equipment frame 4 are installed on the front and rear sides of the first equipment frame 1, respectively. A first conveyor net 15, a second conveyor net 41, and a third conveyor net 51 are installed on the inner sides of the first equipment frame 1, the second equipment frame 4, and the third equipment frame 5, respectively. An automatic feeding component 3 is installed on the upper side of the first equipment frame 1 at the front end of the annealing furnace 2.

[0030] The first conveyor network 15, the second conveyor network 41, and the third conveyor network 51 work together to transport the glass bottles. The third conveyor network 51 is used to transport the formed glass bottles to the front of the first conveyor network 15. The first conveyor network 15 is used to transport the glass bottles into the annealing furnace 2 for annealing treatment. The second conveyor network 41 is used to transport the annealed glass bottles to the subsequent processing steps. The insulation plate 22 insulates the outside of the furnace body 21, improving the insulation effect of the annealing furnace 2 and improving the temperature control accuracy.

[0031] In a preferred embodiment, a support plate 13 is fixedly connected to the inner side of the first equipment frame 1. Multiple sets of first heating plates 14 are fixedly installed on the upper surface of the support plate 13 at a position below the annealing furnace 2. Sealing plates 27 are installed on both the front and rear sides of the annealing furnace 2. Transmission rollers 11 are rotatably connected to both the front and rear ends of the first equipment frame 1. The front and rear ends of the first conveyor net 15 are respectively connected to the transmission rollers 11 on the front and rear sides. A first motor 12 is fixedly installed on the right side of the front end of the first equipment frame 1. The output end of the first motor 12 is fixedly connected to the right end of the transmission roller 11.

[0032] Meanwhile, the first heating plate 14 heats the bottom of the glass bottle, further improving the heating uniformity and ensuring that the glass bottle is heated evenly inside the annealing furnace 2.

[0033] Furthermore, during the glass bottle conveying process, the first motor 12 drives the front transmission roller 11 to be heated, and the two sets of transmission rollers 11 work together to drive the first conveyor net 15 to rotate, thereby conveying the glass bottle.

[0034] In a preferred embodiment, the insulation plate 22 is fixed on the left and right sides and the top of the furnace body 21. Multiple sets of temperature sensors 26 are fixedly installed on the top surface of the furnace body 21. Limiting grooves 25 are opened at both ends of the inner walls on the left and right sides of the furnace body 21. The left and right ends of the sealing plate 27 are slidably connected to the inside of the limiting grooves 25 on both sides. Support frames 28 are fixedly connected to the top of the front and rear ends of the furnace body 21. A hydraulic cylinder 29 is fixedly installed on the top of the support frame 28. The lower end of the piston rod in the hydraulic cylinder 29 is fixedly connected to the upper end of the sealing plate 27.

[0035] In addition, the furnace body 21, the first equipment rack 1, the second equipment rack 4 and the third equipment rack 5 are all made of high-strength stainless steel to ensure the overall structure is stable and reliable. Electric heating tubes are installed inside the first heating plate 14 and the second heating plate 24. The first heating plate 14 and the second heating plate 24 on the lower side of each heating chamber can be individually temperature controlled. The temperature sensor 26 is an infrared thermometer, which can monitor the temperature change inside the furnace body 21 in real time. The electric heating tube temperature control system is adjusted by a PID controller. The infrared thermometer monitors the temperature inside the furnace in real time and feeds the data back to the controller. The controller automatically adjusts the temperature to the set value according to the feedback temperature.

[0036] During operation, the automatic feeding unit 3 neatly arranges the glass bottles onto the surface of the first conveyor belt 15. Then, the hydraulic cylinder 29 lifts the sealing plates 27 on both sides, opening the front and rear ends of the furnace body 21. Next, the first conveyor belt 15 is activated, transporting the unprocessed glass bottles into the furnace body 21 and simultaneously transporting the processed glass bottles to the surface of the second conveyor belt 41. Then, the hydraulic cylinder 29 lowers the sealing plates 27 on both sides, sealing the front and rear ends of the furnace body 21. At this time, the PID controller activates multiple sets of second heating plates 24 and first heating plates 14 heating units to heat the glass bottles inside the furnace body 21. During this process, the automatic feeding unit 3 places the subsequent unprocessed glass bottles back onto the front end of the first conveyor belt 15.

[0037] Specifically, the annealing process is divided into a heating stage, a holding stage, a slow cooling stage, and a rapid cooling stage. During the heating process, the glass bottle is heated from room temperature to the annealing temperature range (550-600℃) to allow the particles inside the glass to acquire sufficient migration ability, preparing for subsequent stress relaxation. The heating rate needs to be slow (generally 15-20℃ / min) to avoid temporary thermal stress caused by excessive temperature gradient. The heating time of the glass bottle is about 10-30 minutes (depending on the thickness of the glass bottle, the thicker the glass, the longer the heating time, to ensure uniform temperature inside and outside). During the heat preservation process, the glass is kept at the annealing temperature for a certain period of time to make the internal temperature uniform, eliminate the temperature gradient generated during the heating process, and eliminate the permanent thermal stress generated during the forming process through stress relaxation. The heat preservation time is the core stage of the annealing process, which is about 50-90 minutes (depending on the thickness of the glass bottle, the thicker the glass, the longer the heating time). During the slow cooling stage, the glass is slowly cooled from the annealing temperature to the strain point temperature (the critical temperature at which the glass transitions from viscoelastic to elastic, approximately 500°C). This prevents the glass from generating new thermal stress due to excessively rapid cooling. The cooling time is approximately 30-60 minutes, and the cooling rate is approximately 5-10°C / min (depending on the glass thickness; the thicker the glass, the slower the cooling rate). During the slow cooling stage, it is essential to ensure that the temperature drops below the strain point temperature. During the rapid cooling phase, the glass bottle is rapidly cooled from the strain point temperature to room temperature at a rate of approximately 10-30°C / min. The thicker the glass bottle, the lower the cooling rate. Example

[0038] See Figures 5 to 8The automatic feeding component 3 includes a first slide 31, a second slide 32, a lifting cylinder 33, a pneumatic gripper 34, and a vision sensor 35. A mounting bracket 16 is fixedly connected to the upper side of the front end of the first equipment frame 1. The left and right ends of the first slide 31 are fixedly connected to the mounting brackets 16 on both sides, respectively. Three sets of positioning grooves 311 are formed on the lower surface of the first slide 31. Two sets of positioning rods 312 are fixedly connected between the inner walls of the left and right sides of the first slide 31. Positioning sleeves 313 are slidably connected to the surfaces of both sets of positioning rods 312. The lower part of the positioning sleeve 313... The end of the first slide block 31 is fixedly connected to the positioning grooves 311 on both the front and rear sides. A threaded rod 314 is provided between the two sets of positioning rods 312. The left end of the threaded rod 314 is rotatably connected to the left wall of the first slide block 31. A second motor 317 is fixedly installed on the right end of the first slide block 31. The output end of the second motor 317 is fixedly connected to the right end of the threaded rod 314 through a coupling. A threaded sleeve 315 is threadedly connected to the surface of the threaded rod 314. The lower end of the threaded sleeve 315 passes through the middle positioning groove 311 and is fixedly connected to the mounting plate 316.

[0039] The first slide block 31 is used to drive the second slide block 32 to slide left and right, thereby driving the lifting cylinder 33, pneumatic gripper 34 and vision sensor 35 to adjust left and right, and the second slide block 32 drives the lifting cylinder 33, pneumatic gripper 34 and vision sensor 35 to adjust back and forth.

[0040] During the adjustment process, the position of the pneumatic gripper 34 is located by the vision sensor 35, and the second motor 317 is controlled by the PLC controller. The second motor 317 is a bidirectional motor. When the second motor 317 rotates forward, it drives the threaded sleeve 315 to slide backward, thereby sliding the mounting plate 316 backward. Conversely, when the second motor 317 rotates in reverse, it drives the threaded sleeve 315 to slide forward, thereby sliding the mounting plate 316 forward.

[0041] In a preferred embodiment, the second slide 32 has the same structure as the first slide 31, and the second slide 32 is perpendicular to the first slide 31. The upper surface of the second slide 32 is fixedly connected to the mounting plate 316 in the first slide 31. The cylinder body in the lifting cylinder 33 is fixedly connected to the mounting plate 316 in the second slide 32. The pneumatic gripper 34 is fixedly installed at the lower end of the piston rod in the lifting cylinder 33. The vision sensor 35 is fixedly installed on the side of the pneumatic gripper 34.

[0042] Specifically, during the placement of glass bottles, the vision sensor 35 is used to position the glass bottles. At this time, the second motor 317, threaded rod 314, threaded sleeve 315 and mounting plate 316 in the first slide block 31 work together to drive the second slide block 32 to slide left and right, thereby driving the pneumatic gripper 34 to slide left and right. At the same time, the second motor 317, threaded rod 314, threaded sleeve 315 and mounting plate 316 inside the second slide block 32 work together to slide the pneumatic gripper 34 back and forth, moving the pneumatic gripper 34 to the upper side of the glass bottle. Then, the lifting cylinder 33 pushes the pneumatic gripper 34 downward, and with the cooperation of the vision sensor 35, the glass bottle is accurately gripped. Then, the glass bottle is neatly placed on the upper side of the first conveyor network 15.

[0043] The working principle of this invention is as follows: Multiple independent heating chambers are formed inside the furnace body 21 by utilizing the partition plate 23 and the second heating plate 24. The temperature of each chamber can be independently controlled. The sides of the furnace body 21 are insulated by the insulation plate 22, reducing heat loss and improving temperature control accuracy. Furthermore, the distance between the heat source and the multiple sets of glass bottles is the same, effectively improving the uniformity of heating the glass bottles, increasing their quality, and reducing the defect rate. Simultaneously, the first conveyor network 15, the second conveyor network 41, and the third conveyor network 51 are used to transport the glass bottles. The automatic feeding component 3 automatically places the glass bottles on the surface of the third conveyor network 51 onto the first... The glass bottles are moved from the surface of the first conveyor network 15 to the interior of the annealing furnace 2, improving feeding efficiency and safety, and increasing product processing efficiency. At the same time, the annealed glass bottles are automatically conveyed to the surface of the second conveyor network 41, which then transports them to subsequent processing steps. Channels are provided on both the front and rear sides of the furnace body 21, and are sealed by two sets of hydraulic cylinders 29 and sealing plates 27. The first conveyor network 15, the second conveyor network 41, the third conveyor network 51, and the automatic feeding component 3 work together to achieve automatic feeding and loading, improving the automation level of the equipment, reducing manual intervention, and lowering production costs.
