Description

Technical Field

[0001] This invention relates to the field of glass product manufacturing and processing equipment, and in particular to an energy-saving glass bottle annealing device. Background Technology

[0002] Glass bottles, as a common packaging container, are widely used in the food and beverage industries. Annealing is a crucial process to ensure the quality and safety of glass bottles. Traditional glass bottle annealing equipment uses electric or gas heating, employing a slow heating, holding, and cooling process to eliminate internal stresses, thereby improving heat resistance and mechanical strength. While effective, this traditional method is energy-intensive, especially in large-scale production, where energy consumption becomes a significant factor limiting enterprise profitability.

[0003] Currently, commonly used glass bottle annealing equipment mainly includes two types: electric heating furnaces and gas heating furnaces. Electric heating furnaces have the advantages of high temperature control accuracy and convenient operation, but they also have the problem of high energy consumption. Gas heating furnaces have relatively low energy consumption due to their higher combustion efficiency, but their temperature control accuracy is not as good as that of electric heating furnaces, which can easily lead to temperature fluctuations and affect the annealing effect. In addition, both heating methods have the problem of uneven heating, resulting in poor annealing effect of glass bottles in some areas and increasing the defect rate.

[0004] Existing glass bottle annealing equipment has significant shortcomings in terms of energy consumption. Especially in large-scale production, energy consumption has become an important factor restricting enterprise efficiency. In addition, the uneven heating caused by traditional heating methods also seriously affects the annealing effect, increases the defect rate, and reduces production efficiency.

[0010] Both the annealing furnace body and the outer side of the feeding conveyor belt are equipped with pushing components to push the glass bottles into the next process.

[0012] Preferably, the pushing assembly includes a second support baffle, and two first electric push rods are installed on the inner side of the second support baffle. The driving end of the first electric push rod is equipped with an arc-shaped push plate.

[0013] Preferably, connecting brackets are fixedly connected to both the left and right sides of the annealing furnace body, a control panel is provided on the outside of the annealing furnace body, and multiple adsorption plates are provided inside the main conveyor belt, one of which is located below the cooling fan.

[0014] Preferably, a circulating water pipe is installed inside the main conveyor belt, a nitrogen delivery pipe is installed inside the annealing furnace body, a temperature probe is installed on the outside of the circulating water pipe, and multiple nitrogen nozzles are installed on the outside of the nitrogen delivery pipe. The temperature probe, nitrogen nozzles, and control panel are electrically connected.

[0015] Preferably, an air curtain isolation fan is installed at both the inlet and outlet of the annealing furnace body, the circulating water pipe is located above the cooling fan, and the nitrogen delivery pipe is located above the main conveyor belt.

[0016] Preferably, the annealing furnace body is provided with multiple infrared heaters, and multiple heat insulation plates are installed inside the annealing furnace body. A high-temperature resistance wire is installed on the inner side of the heat insulation plate through an insulating fixing block. The control panel is electrically connected to the high-temperature resistance wire. Multiple second electric push rods are installed on the left and right sides inside the annealing furnace body. The first limiting connecting rod is slidably connected inside the limiting groove, and the mounting bracket is slidably connected to the outside of the second limiting connecting rod.

[0017] Preferably, the infrared heater is installed at the drive end of the second electric push rod and at the bottom of the mounting bracket, and heat insulation gates are installed on both the front and rear sides of the heat insulation plate to form a dynamic thermal isolation structure, with one of the heat insulation plates located inside the main conveyor belt.

[0018] In summary, the present invention has at least one of the following beneficial technical effects:

[0019] 1. This invention utilizes a stepped heating system consisting of a closed annealing furnace body, multiple sets of infrared heaters in the preheating chamber, and a high-temperature resistance wire array in the main heating chamber. The annealing furnace body is equipped with multi-layer heat insulation plates to block heat leakage. Combined with the penetrating radiation heating of the infrared heaters installed on the top and side walls of the preheating chamber, the surface of the glass bottle is rapidly and uniformly heated. The high-temperature resistance wires arranged at the bottom and side walls of the main heating chamber form a stable high-temperature field, avoiding the thermal inertia loss of traditional heating methods and reducing ineffective energy consumption.

[0020] 2. This invention utilizes a dynamic thermal isolation system comprised of an adjustment component, a second electric push rod, an air curtain isolation fan, and a heat-insulating gate. The adjustment component's screw drive drives the mounting bracket to synchronize the position of the top infrared heater. The second electric push rod then drives the heating height of the infrared heaters on both sides to change. Combined with the air curtain isolation fan forming a vertical airflow barrier inside the annealing furnace body, and the heat-insulating gate adjusting its opening and closing in real time according to the temperature gradient, this eliminates the thermal field difference between the furnace cavity edge and the center area, ensuring synchronized heating curves of the inner and outer walls of the glass bottle and improving stress relief.

[0021] 3. This invention utilizes the forced convection system formed by the cooling chamber air-cooling components, the contact heat exchange of the circulating water pipes, and the synergistic effect of the nitrogen nozzles. By using the cooling fan to form a uniform airflow coverage layer on the top and sides of the cooling chamber, the circulating water pipes are laid out along the transmission path, and the nozzles of the nitrogen nozzles spray low-temperature nitrogen gas onto the surface of the glass bottle, it breaks through the traditional cooling efficiency and shortens the annealing cycle. At the same time, the arc-shaped push plate of the pusher component and the compression spring and limit telescopic rod of the buffer component are used to achieve impact-free transmission of the bottle body, which enhances the stability of continuous production.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be further described in detail below.

[0036] Reference Appendix Figure 1 Appendix Figure 6 and attached Figure 7 This invention provides an energy-saving glass bottle annealing device, including an annealing furnace body 1, a main conveyor belt 6 installed inside the annealing furnace body 1, and an adjustment component 13 inside the annealing furnace body 1; the adjustment component 13 includes a drive motor 131, the drive motor 131 is located outside the annealing furnace body 1, a lead screw 132 is installed at the drive end of the drive motor 131, a transmission slider 133 is provided outside the lead screw 132, a limiting slide plate 134 is fixedly connected to the bottom of the transmission slider 133, a plurality of limiting slide grooves 135 are opened on the outside of the limiting slide plate 134, a plurality of first limiting connecting rods 136 are slidably connected inside the limiting slide plate 134, an installation bracket 137 is fixedly connected to the bottom of the first limiting connecting rods 136, and a plurality of second limiting connecting rods 138 are fixedly connected inside the annealing furnace body 1;

[0037] Specifically, the annealing furnace body 1 provides a closed heat treatment space for the glass bottle annealing process. The main conveyor belt 6 serves as a carrying platform, driving the glass bottles to continuously pass through various temperature zones of the annealing furnace body 1 at a set speed. The drive motor 131 of the adjustment component 13 is located on the outside of the annealing furnace body 1 to avoid damage caused by high temperature. The rotational force output by the drive motor 131 is converted into linear driving force through the lead screw 132. The transmission slider 133 is threadedly engaged with the lead screw 132 to realize forward or backward movement. The limiting slide plate 134 moves synchronously with the transmission slider 133. The sliding of the first limiting connecting rod 136 in the limiting slide groove 135 causes the mounting bracket 137 to move on the second limiting connecting rod 138. At the same time, the second limiting connecting rod 138 constrains the movement trajectory of the mounting bracket 137. Through the constraints of the limiting slide plate 134 and the second limiting connecting rod 138, the mounting bracket 137 can carry the heating element and move synchronously and shorten the distance in the plane above the main conveyor belt 6.

[0038] Reference Appendix Figure 5 and attached Figure 9 The annealing furnace body 1 is equipped with an air-cooling component 20 for initial cooling of the glass bottles and exhaust of hot air inside the annealing furnace body 1. The air-cooling component 20 includes an air inlet channel 201, which is located on the outside of the annealing furnace body 1 and communicates with it. Multiple cooling fans 202 and multiple heat dissipation fans 203 are installed inside the annealing furnace body 1. An air outlet channel 204 is provided on the bottom side inside the annealing furnace body 1 and communicates with it.

[0039] Specifically, the air-cooled component 20 performs the first stage of forced convection cooling. The air inlet channel 201 serves as a supplementary inlet for cold air, introducing ambient temperature air from outside the annealing furnace body 1. The cooling fan 202 actively blows the cold air introduced by the air inlet channel 201 at high speed toward the surface of the glass bottle, quickly removing the heat from the surface of the glass bottle through impact convection. The function of the cooling fan 203 is to extract the overall hot air in the cooling zone of the annealing furnace body 1, preventing heat from accumulating in the furnace and maintaining the temperature of the cooling zone. The air outlet channel 204 is located on the bottom side, and in conjunction with the suction action of the cooling fan 203, it forces the heated high-temperature exhaust gas out of the annealing furnace body 1, completing the gas exchange cycle of the entire air-cooled component 20.

[0040] Reference Appendix Figure 2 - Appendix Figure 4 An annealing furnace body 1 is provided with a feeding conveyor belt 7 on its outer side and a discharging conveyor belt 8 on the side of the annealing furnace body 1 away from the feeding conveyor belt 7. A transition plate 10 is provided between the annealing furnace body 1 and the feeding conveyor belt 7 and the discharging conveyor belt 8. A baffle plate 9 is provided on the top of both the feeding conveyor belt 7 and the discharging conveyor belt 8.

[0041] Specifically, the feeding conveyor belt 7 and the discharging conveyor belt 8 constitute the input and output ends of the glass bottles in the annealing furnace body 1, respectively, ensuring the continuity of the automated production line. The function of the transition plate 10 is to bridge the physical gaps between the feeding conveyor belt 7 and the main conveyor belt 6, and between the main conveyor belt 6 and the discharging conveyor belt 8. The design of the transition plate 10 ensures that the bottom of the glass bottle is stably supported during the handover process, preventing the glass bottle from tipping over due to gaps or height differences. The baffle plate 9 is installed on the top sides of the feeding conveyor belt 7 and the discharging conveyor belt 8 to provide lateral trajectory constraints for the glass bottle, ensuring that the glass bottle stays near the center line of the conveyor belt when entering or leaving the annealing furnace body 1, and providing a positioning reference for subsequent pushing or buffering actions.

[0042] Reference Appendix Figure 5 Appendix Figure 11 and attached Figure 12 Both the annealing furnace body 1 and the feeding conveyor belt 7 are equipped with pushing components 12 to push glass bottles into the next process. Both the annealing furnace body 1 and the discharging conveyor belt 8 are equipped with buffer components 11 to buffer the glass bottles during the pushing process. The buffer component 11 includes a first support baffle 114, with multiple compression springs 113 arranged inside the first support baffle 114. The other end of each compression spring 113 is fixedly connected to a buffer plate 111. A limit telescopic rod 112 is slidably connected inside the first support baffle 114, with the other end of the limit telescopic rod 112 fixedly connected to the inside of the buffer plate 111. The pushing component 12 includes a second support baffle 122, with two first electric push rods 121 installed inside the second support baffle 122. The driving end of each first electric push rod 121 is equipped with an arc-shaped push plate 123.

[0043] Specifically, the pushing assembly 12 and the buffer assembly 11 work together to achieve smooth transfer of the glass bottle between the annealing furnace body 1 and the feeding conveyor belt 7 and the discharging conveyor belt 8. The first support baffle 114 is the fixed base of the buffer assembly 11. The buffer plate 111 is the force-bearing surface that is in direct contact with the glass bottle. The compression spring 113 is the main energy-absorbing element. When the buffer plate 111 is impacted, the compression spring 113 is compressed, converting the kinetic energy of the glass bottle into elastic potential energy. The limiting telescopic rod 112 is located on the first support baffle 114. The internal sliding constraint allows the buffer plate 111 to only reciprocate linearly along the pushing direction, preventing the buffer plate 111 from deflecting or getting stuck when subjected to uneven force. The second support baffle 122 is the fixed base of the pushing assembly 12. The first electric push rod 121 provides linear driving force to achieve reciprocating motion. The arc surface design of the arc-shaped push plate 123 fits the cylindrical outer wall of the glass bottle, increasing the contact area, dispersing the pushing stress, and preventing damage to the glass bottle due to excessive local pressure during the pushing process. It also has a certain centering effect.

[0044] Reference Appendix Figure 1 Appendix Figure 3 and attached Figure 10 The annealing furnace body 1 is fixedly connected to the left and right sides with connecting brackets 2. The annealing furnace body 1 is equipped with a control panel 3 on the outside. The main conveyor belt 6 is equipped with multiple adsorption plates 5, one of which is located below the cooling fan 202.

[0045] Specifically, the connecting bracket 2 provides connection support for the annealing furnace body 1, ensuring that the annealing furnace body 1 maintains the relative position and horizontal height with the feeding conveyor belt 7 and the discharging conveyor belt 8. The control panel 3 is the central control unit of the entire device, integrating a human-machine interface and a PLC controller, used to set and monitor the annealing temperature curve, conveyor belt speed, fan speed, and execute operations. When the cooling fan 202 blows downward at high speed, the airflow passes through the narrow area between the bottom of the glass bottle and the adsorption plate 5, generating negative pressure, thereby forming a downward adsorption force at the bottom of the glass bottle. The adsorption force is used to resist the blowing force of the cooling fan 202, preventing the lightweight glass bottle from shifting or tipping over during the strong wind cooling process.

[0046] Reference Appendix Figure 5 and attached Figure 9 The main conveyor belt 6 is equipped with a circulating water pipe 21, the annealing furnace body 1 is equipped with a nitrogen delivery pipe 24, a temperature probe 22 is installed on the outside of the circulating water pipe 21, and multiple nitrogen nozzles 23 are installed on the outside of the nitrogen delivery pipe 24. The temperature probe 22, nitrogen nozzles 23 and control panel 3 are electrically connected.

[0047] Specifically, the circulating water pipe 21 is installed inside the main conveyor belt 6, which cools the bottom of the glass bottle or the main conveyor belt 6 itself through conduction heat exchange, achieving gentle stress release. The nitrogen delivery pipe 24 serves as the delivery manifold for high-pressure, low-temperature nitrogen. The nitrogen nozzle 23 is the actuator for nitrogen cooling, which sprays the low-temperature nitrogen gas after liquid nitrogen vaporization onto the surface of the glass bottle for rapid deep cooling, used to handle critical phase change points and prevent secondary stress generation. The temperature probe 22 is used to monitor the outlet water temperature of the circulating water pipe 21 in real time. The rate of change of water temperature reflects the cooling load of the glass bottle. The control panel 3 receives the signal from the temperature probe 22. When it detects that the cooling capacity of the circulating water pipe 21 has reached its upper limit or is insufficient, the control panel 3 will activate the nitrogen nozzle 23 to perform supplementary cooling, forming a closed-loop feedback control system.

[0048] Reference Appendix Figure 1 and attached Figure 9 An air curtain isolation fan 4 is installed at both the inlet and outlet of the annealing furnace body 1. The circulating water pipe 21 is located above the cooling fan 203, and the nitrogen delivery pipe 24 is located above the main conveyor belt 6.

[0049] Specifically, the air curtain isolation fan 4 blows high-speed vertical airflow at the inlet and outlet of the annealing furnace body 1 to form an air curtain, which is used to physically block the convection exchange between the hot air inside the annealing furnace body 1 and the cold air in the outside environment, reduce heat loss, and maintain the temperature stability of the hot zone inside the furnace. It is one of the key structures for achieving energy saving. The circulating water pipe 21 is located above the cooling fan 203. Before the high-temperature waste gas in the furnace drawn by the cooling fan 203 is discharged from the exhaust channel 204, it will flow through the outer wall of the circulating water pipe 21, transferring the waste heat to the water medium in the circulating water pipe 21 to realize the utilization of waste heat. The nitrogen delivery pipe 24 is set above the main conveyor belt 6 to ensure that the nitrogen nozzle 23 sprays low-temperature nitrogen evenly onto the top and side wall of the glass bottle located on the main conveyor belt 6.

[0050] Reference Appendix Figure 6 - Appendix Figure 8 The annealing furnace body 1 is equipped with multiple infrared heaters 15 and multiple heat insulation plates 17. A high-temperature resistance wire 18 is installed on the inner side of the heat insulation plate 17 through an insulating fixing block 19. The control panel 3 is electrically connected to the high-temperature resistance wire 18. Multiple second electric push rods 14 are installed on the left and right sides inside the annealing furnace body 1. The first limit connecting rod 136 is slidably connected inside the limit slide groove 135. The mounting bracket 137 is slidably connected to the outside of the second limit connecting rod 138. The infrared heaters 15 are installed at the drive end of the second electric push rod 14 and the bottom of the mounting bracket 137. Heat insulation gates 16 are installed on both the front and rear sides of the heat insulation plate 17 to form a dynamic thermal isolation structure. One of the heat insulation plates 17 is located inside the main conveyor belt 6.

[0051] Specifically, the infrared heater 15 preheats the glass bottle using radiant heat, the high-temperature resistance wire 18 serves as the main heating element, responsible for heating the glass bottle to the annealing temperature, the heat insulation plate 17 adds a heat insulation layer to the annealing furnace body 1 to reduce heat loss to the outer shell of the annealing furnace body 1, the insulating fixing block 19 is used to fix the high-temperature resistance wire 18 to the inside of the heat insulation plate 17 and provides high-temperature electrical insulation, the control panel 3 adjusts the power supplied to the high-temperature resistance wire 18 to control the heating temperature, and the second electric push rod 14 provides vertical support for the infrared heater 15. The directional lifting adjustment, combined with the adjustment component 13, provides the effect of synchronous translation adjustment of the spacing. The infrared heater 15 has multi-directional adjustment to adapt to glass bottles of different specifications. The heat insulation gate 16 is a movable heat barrier installed between the heat insulation plates 17, used to dynamically open and close between different processing stages to block heat flow. The heat insulation plate 17 set inside the main conveyor belt 6 serves as a heat shield layer to protect the chain, mesh belt, or roller mechanical transmission components of the main conveyor belt 6 from direct heat radiation baking by the high-temperature resistance wire 18 above, thus extending the service life of the main conveyor belt 6.

[0052] Working principle: During feeding, the glass bottles to be annealed are conveyed to the inlet of the annealing furnace body 1 via the feeding conveyor belt 7. The first electric push rod 121 of the pushing assembly 12 drives the arc-shaped push plate 123 to push the glass bottles into the annealing furnace body 1. The glass bottles enter the main conveyor belt 6 through the transition plate 10. At the same time, the adsorption plate 5 provides adsorption force, and the baffle plate 9 constrains the glass bottle's transmission trajectory to prevent the glass bottles from tipping over. Subsequently, the glass bottles enter the preheating stage, and the infrared heater 15 is activated. The top infrared heater 15 is fixed to the first adjustment assembly 13 via the mounting bracket 137. At the bottom of the limiting connecting rod 136, the drive motor 131 drives the lead screw 132 to rotate, which drives the transmission slider 133 to move along the limiting slide plate 134. The first limiting connecting rod 136 slides in the limiting slide groove 135, so that the infrared heater 15 can achieve synchronous adjustment of position. At the same time, the infrared heaters 15 on both sides are adjusted up and down by the drive of the second electric push rod 14 to achieve a suitable heating position. The air curtain isolation fan 4 forms a vertical airflow barrier at the inlet and outlet of the annealing furnace body 1, thereby achieving the effect of sealing the annealing furnace body 1.

[0053] After the glass bottle enters the main heating zone, the high-temperature resistance wire 18 is installed inside the heat insulation plate 17 via the insulating fixing block 19 and begins to heat. The control panel 3 adjusts the power of the high-temperature resistance wire 18 in real time, and the heat insulation gate 16 dynamically adjusts its opening and closing according to the temperature gradient, forming a dynamic thermal isolation structure in conjunction with the air curtain isolation fan 4. The circulating water pipe 21 built into the main conveyor belt 6 absorbs the residual heat above the cooling fan 203 and discharges it outside the annealing furnace body 1. The ceramic fiber liner of the heat insulation plate 17 blocks the heat leakage from the main heating zone, and the adsorption plate 5 below the cooling fan 202 enhances airflow adsorption to maintain the stability of the glass bottle transmission.

[0054] After the heated glass bottle enters the cooling zone, the cooling fan 202 and heat dissipation fan 203 of the air-cooling component 20 are activated. The air inlet channel 201 introduces cold air from the outside, and the air outlet channel 204 discharges hot air to form convection, which initially cools the glass bottle. The circulating water pump of the water-cooling device drives the cooling water to flow in the circulating water pipe 21. Through contact heat exchange via stainless steel pipes, the glass bottle is cooled again. Finally, nitrogen gas is sprayed from the nitrogen nozzle 23 through the nitrogen delivery pipe 24 to cover the surface of the bottle and cool the glass bottle to room temperature. The temperature probe 22 monitors the temperature of the circulating water pipe 21 in real time and adjusts the nitrogen injection volume in conjunction with the control panel 3. Through the sequential action of the three-stage cooling medium, the air-cooling component 20 prioritizes reducing the surface temperature of the glass bottle, the circulating water pipe 21 eliminates internal residual stress, and the nitrogen cooling prevents secondary stress cracks.

[0055] After cooling, the glass bottles are conveyed to the discharge port via the main conveyor belt 6. The arc-shaped pusher plate 123 of the pusher assembly 12 pushes the glass bottles to the discharge conveyor belt 8. The compression spring 113 and the limiting telescopic rod 112 of the buffer assembly 11 absorb the impact force of the pusher. The buffer plate 111 supports the glass bottles to avoid collision. The glass bottles are transferred to the discharge conveyor belt 8 via the transition plate 10. The baffle plate 9 prevents the glass bottles from accidentally slipping and maintains the transmission trajectory. Finally, the glass bottles are conveyed to the next process to complete one glass bottle annealing process.
