Description

Technical Field

[0001] This utility model relates to the field of crystal glass technology, specifically to a crystal glass annealing and heat preservation device. Background Technology

[0002] Annealing is a crucial step in the manufacturing process of crystal glass. During the forming process, a large amount of thermal stress is generated inside the crystal glass. If this stress is not effectively relieved, it can cause problems such as cracking and deformation during subsequent processing, transportation, or use, seriously affecting product quality and service life.

[0003] Chinese Patent CN222729669U discloses a crystal glass annealing and heat preservation device, including a workbench. The device is characterized by: a conveyor belt on the workbench for moving crystal glass products; a heat preservation annealing device on the top of the workbench for annealing the crystal glass products; symmetrically arranged transition components inside the heat preservation annealing device; a collection box on the top of the heat preservation annealing device for collecting excess heat; a first fan and a second fan at the bottom of the collection box for guiding heat energy; a second electric valve and a temperature sensor inside the collection box; a first electric valve connected to the top of the collection box for discharging heat from the collection box; and a universal controller installed on one side wall of the collection box.

[0004] The aforementioned patents can solve the corresponding technical problems, realize the collection and reuse of excess heat, and achieve the purpose of energy saving. However, the aforementioned patents still have drawbacks in actual implementation:

[0005] First, the aforementioned patent places the crystal glass on a conveyor belt during the annealing process. This causes the entire bottom of the crystal glass to be in contact with the surface of the conveyor belt. The conveyor belt material typically has a certain degree of thermal conductivity, which affects the heat transfer to the bottom of the glass, resulting in uneven heating of the glass, affecting the stress relief effect, and reducing the product qualification rate. Second, during the annealing process, the two ends of the device are in a state of air circulation, causing a large amount of internal heat to be lost. To maintain the temperature required for annealing, the equipment needs to consume more energy, increasing production costs. At the same time, heat loss also disrupts the temperature uniformity within the device, causing uneven cooling rates in different parts of the crystal glass, generating new stress, and seriously affecting the annealing quality. Utility Model Content

[0006] The purpose of this invention is to provide a crystal glass annealing and heat preservation device, which solves the problems of uneven local heating of crystal glass during the annealing process caused by existing crystal glass annealing and heat preservation devices, which affect the stress relief effect, reduce the product qualification rate, have poor sealing performance, require more energy consumption, increase production costs, and seriously affect the annealing quality.

[0007] To achieve the above objectives, the main technical solution adopted by this utility model includes: a crystal glass annealing and heat preservation device, comprising: an annealing and heat preservation chamber, a door movably connected to one side of the annealing and heat preservation chamber, a support component for placing crystal glass installed at the bottom inner side of the annealing and heat preservation chamber, and a heater and a temperature sensor fixedly installed on the inner side wall of the annealing and heat preservation chamber; wherein, a ventilation component is provided on the annealing and heat preservation chamber; a controller is fixedly installed on one side of the annealing and heat preservation chamber, and the heater, the temperature sensor, and the ventilation component are all controlled by the controller.

[0008] As a preferred technical solution, the supporting component includes at least two slide bars, which are connected and fixed together by a connecting plate. A first slide groove is provided at the bottom of the annealing and heat preservation box. The slide bars are slidably installed inside the first slide groove. A support frame is fixedly installed on the top of the slide bars, and the crystal glass is placed on the support frame.

[0009] As a preferred technical solution, the support frame is set at an inclined angle, and the crystal glass leans against the support surface of the support frame.

[0010] As a preferred technical solution, the support surface of the support frame is provided with hollow holes, and the contact part between the support frame and the crystal glass is provided with a silicone pad.

[0011] As a preferred technical solution, the annealing and heat preservation box body is fixedly connected to a docking plate on one side of the box door. The docking plate is provided with a second sliding groove that is aligned with the first sliding groove. The slide bar can slide between the first sliding groove and the second sliding groove simultaneously.

[0012] As a preferred technical solution, the annealing and insulation box body is provided with an insertion hole, and the box door is fitted into the inner wall of the insertion hole, and the box door can be freely inserted into the insertion hole to complete the closure and sealing of the annealing and insulation box body.

[0013] As a preferred technical solution, handles are fixedly installed on the box door and the connecting plate respectively.

[0014] As a preferred technical solution, the ventilation component includes at least two ventilation pipes, which are respectively fixedly connected to the top and side of the annealing and insulation box.

[0015] A solenoid valve is fixedly installed on the ventilation pipe, and the solenoid valve is electrically connected to the controller.

[0016] This utility model has at least the following beneficial effects:

[0017] This utility model provides a crystal glass annealing and heat preservation device. By setting up a support frame, the contact area between the crystal glass and the support surface can be reduced, avoiding excessive local stress accumulation caused by placing the entire crystal glass on the table in the traditional way. This reduces the possibility of cracking or deformation of the glass due to uneven stress during the annealing process, improves the product yield, and allows the air around the glass to flow more freely. Hot air can flow around the glass surface more smoothly, allowing heat to be transferred to all parts of the glass quickly and evenly. Compared with a large contact area with the table surface that hinders heat exchange, this device can shorten the time for the glass to reach the target annealing temperature, accelerate the annealing process, and improve production efficiency.

[0018] The design of the door fitting into the inner wall of the socket ensures a tight fit between the door and the annealing and insulation chamber, effectively preventing heat loss and the entry of cold air from the outside. This maintains a constant temperature inside the chamber, creating a stable temperature environment for crystal glass annealing, improving the annealing effect and product quality, reducing energy consumption, and saving production costs.

[0019] With the help of solenoid valves and ventilation pipes distributed on the top and sides of the annealing insulation chamber, the air circulation speed and ventilation volume inside the chamber can be precisely adjusted according to the needs of different stages of the annealing process under the control of the controller. This accelerates heat dissipation during the cooling stage, ensures the smooth progress of the annealing process, and improves the quality and efficiency of annealing. Attached Figure Description

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Example

[0030] Please refer to Figures 1 to 5 As shown, this embodiment provides a crystal glass annealing and heat preservation device, including: an annealing and heat preservation chamber 1, a door 2 movably connected to one side of the annealing and heat preservation chamber 1, a support component for placing crystal glass 501 installed at the bottom inner side of the annealing and heat preservation chamber 1, and a heater 6 and a temperature sensor 7 fixedly installed on the inner side wall of the annealing and heat preservation chamber 1; wherein, a ventilation component is provided on the annealing and heat preservation chamber 1; a controller 10 is fixedly installed on one side of the annealing and heat preservation chamber 1, and the heater 6, temperature sensor 7, and ventilation component are all controlled by the controller 10. By installing the heater 6 and temperature sensor 7 on the inner side wall of the annealing and heat preservation chamber 1 and controlling them by the controller 10, It can precisely adjust and monitor the temperature inside the annealing and insulation chamber 1, providing a stable temperature environment for the annealing of crystal glass 501, effectively eliminating internal stress in the glass and improving product quality. The chamber door 2, connected to one side of the annealing and insulation chamber 1, facilitates the placement and removal of crystal glass 501 by operators, and also aids in equipment maintenance and repair, as well as the sealing and opening / closing of the annealing and insulation chamber 1. The ventilation components actively promote air circulation and exchange, accelerating heat dissipation, shortening the entire annealing cycle, and improving production efficiency. They also help to promptly remove any hot exhaust gases that may be generated inside the annealing and insulation chamber, maintaining a good annealing environment.

[0031] The supporting component includes at least two slide bars 4, which are connected and fixed together by a connecting plate 401. A first groove 3 is provided at the bottom inner side of the annealing and insulation chamber 1. The slide bars 4 are slidably installed inside the first groove 3. A support frame 5 is fixedly installed on the top of the slide bars 4. The crystal glass 501 is placed on the support frame 5 and slides within the first groove 3 via the slide bars 4. This facilitates the removal or insertion of the supporting component along with the crystal glass 501 from the annealing and insulation chamber 1, improving operation and work efficiency. The connecting plate 401 connects and fixes the two slide bars 4, making the supporting component more stable and better able to support the crystal glass 501, preventing it from shaking or shifting during the annealing process. In addition, the support frame 5 reduces the contact area between the crystal glass 501 and the support surface, avoiding excessive local stress accumulation caused by placing the entire crystal glass 501 on the table. This reduces the possibility of cracking or deformation of the glass due to uneven stress during annealing, improving the product yield. Moreover, reducing the contact area allows for freer airflow around the glass, enabling hot air to flow more smoothly around the glass surface and quickly and evenly transfer heat to all parts of the glass. Compared to a large contact area on the table that hinders heat exchange, this shortens the time it takes for the glass to reach the target annealing temperature, accelerates the annealing process, and improves production efficiency.

[0032] The support frame 5 is set at an inclined angle, and the crystal glass 501 leans against the support surface of the support frame 5. As the crystal glass 501 leans against the inclined support frame 5, gravity will generate a component force along the inclined surface of the support frame 5, which will cause the glass to fit tightly against the support frame 5 and form a stable placement state.

[0033] The support frame 5 has a perforated hole 502 on its support surface, and a silicone pad is provided at the contact point between the support frame 5 and the crystal glass 501. The perforated hole 502 on the support surface can accelerate air circulation and help the glass dissipate heat evenly during the annealing process. The silicone pad at the contact point is soft, which can not only prevent the glass from directly contacting the support frame 5 and causing wear and scratches, but also buffer external forces to prevent the glass from being damaged during placement and annealing.

[0034] Among them, the annealing and heat preservation box 1 is fixedly connected to a docking plate 8 on one side of the box door 2. The docking plate 8 has a second sliding groove 801 that is aligned with the first sliding groove 3. The slide bar 4 can slide between the first sliding groove 3 and the second sliding groove 801 at the same time. By aligning the second sliding groove 801 on the docking plate 8 with the first sliding groove 3, the sliding path of the slide bar 4 is extended, giving the operator more operating space when placing and taking out the crystal glass 501, reducing the difficulty of operation and improving the safety of operation.

[0035] The annealing and heat preservation chamber 1 has an insertion hole 201. The chamber door 2 is fitted into the inner wall of the insertion hole 201 and can be freely inserted into the insertion hole 201 to complete the closure and sealing of the annealing and heat preservation chamber 1. The design of the chamber door 2 fitting into the inner wall of the insertion hole 201 ensures that the chamber door 2 and the annealing and heat preservation chamber 1 are tightly fitted, effectively preventing heat loss and the entry of cold air from the outside, ensuring a constant temperature inside the chamber, creating a stable temperature environment for the annealing of crystal glass 501, and improving the annealing effect and product quality.

[0036] Handles 202 are fixedly installed on the box door 2 and the connecting plate 401 respectively. The handles 202 on the box door 2 and the connecting plate 401 provide the operator with a point of leverage, making it easier to open and close the box door 2 and push and pull the support components, making the operation process easier and less strenuous, reducing labor intensity and improving work efficiency.

[0037] The ventilation component includes at least two ventilation pipes 9, which are fixedly connected to the top and side of the annealing insulation chamber 1, respectively. A solenoid valve 901 is fixedly installed on the ventilation pipe 9. The solenoid valve 901 is electrically connected to the controller 10. Through the ventilation pipes 9 distributed on the top and side of the annealing insulation chamber 1 and the solenoid valve 901, under the control of the controller 10, the air circulation speed and ventilation volume in the chamber can be precisely adjusted according to the needs of different stages of the annealing process. During the cooling stage, heat dissipation is accelerated, ensuring the smooth progress of the annealing process and improving the annealing quality and efficiency.

[0038] It is worth noting that heater 6 can be an SRY2 type tubular electric heater, temperature sensor 7 can be a PT100 type, solenoid valve 901 can be a ZQDF type steam solenoid valve, and controller 10 can be a Siemens S7-200SMART series PLC controller.

[0039] As is well known to those skilled in the art, the working principles and wiring methods of heater 6, temperature sensor 7, solenoid valve 901 and controller 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can select any model according to their needs or convenience.

[0040] Working principle:

[0041] Loading process: First, grasp the handle 202 on the door 2 and pull the door 2 out of the insertion hole 201 of the annealing and insulation chamber 1 to open the door. The fitting design of the insertion hole 201 and the door 2 ensures a good sealing effect when closing it later. Then, pull the handle 202 on the connecting plate 401 to make the slide bar 4 slide in the first slide groove 3 and the second slide groove 801 of the docking plate 8, pulling the support component out part of the annealing and insulation chamber 1. Then, lean the crystal glass 501 against the support surface of the support frame 5. The support frame 5 is set at an inclined angle, and... The support surface is equipped with a silicone pad, which can effectively reduce the contact area with the glass and avoid damage to the glass surface. At the same time, the hollow holes 502 on the support surface further reduce the contact area and facilitate air circulation. Then, the support component with the crystal glass 501 placed on it is pushed back into the annealing and heat preservation box 1 through the slide bar 4 along the first slide groove 3 and the second slide groove 801. Finally, the handle 202 on the box door 2 is pushed to make the box door 2 fit tightly into the insertion hole 201, completing the closure and sealing of the annealing and heat preservation box 1, preventing heat loss and the entry of outside air.

[0042] Annealing heating and heat preservation stage: The target temperature and heat preservation time required for annealing are set on the controller 10, and the heater 6 is controlled to start heating the inside of the annealing heat preservation chamber 1. Since the annealing heat preservation chamber 1 is well sealed, the heat can be effectively concentrated, improving the heating efficiency. The temperature sensor 7 monitors the temperature inside the annealing heat preservation chamber 1 in real time and feeds the data back to the controller 10. The controller 10 adjusts the power of the heater 6 according to the feedback to ensure that the temperature rises according to the predetermined curve. The reduced contact area makes the glass heated more evenly, which is conducive to improving the annealing quality. When the temperature reaches the set target temperature, the controller 10 controls the heater 6 to maintain an appropriate power to stabilize the temperature and enter the heat preservation stage to eliminate the internal stress of the glass. The good sealing performance of the annealing heat preservation chamber 1 helps to maintain temperature stability.

[0043] Cooling process: After the heat preservation time ends, the controller 10 controls the heater 6 to stop heating. The solenoid valve 901 can be opened for ventilation as needed to accelerate heat dissipation. The temperature sensor 7 continuously monitors the temperature. The controller 10 adjusts the ventilation frequency and other operations according to the cooling requirements. The reduced contact area helps the glass dissipate heat faster and more evenly. Throughout the cooling process, the sealed state of the annealing and heat preservation chamber 1 helps control the cooling rate and ensures that the cooling process meets the process requirements.
