Description

Technical Field

[0001] This utility model relates to the field of glass processing, and in particular to a low-temperature glass processing device. Background Technology

[0002] Glass is a material with a relatively small coefficient of thermal expansion, but it still expands or contracts with changes in temperature. If the temperature changes too quickly or too high during processing, thermal stress will be generated inside the glass. Thermal stress may cause microcracks or even breakage of the glass. Low-temperature treatment can effectively avoid thermal stress caused by rapid heating or cooling of glass. By heating or cooling slowly, the temperature distribution inside the glass is more uniform, thereby reducing the generation of thermal stress.

[0003] Low-temperature chambers provide a uniform and stable low-temperature environment. Temperature uniformity is crucial during glass processing. Low-temperature chambers are typically equipped with precise temperature control systems that enable slow and uniform heating or cooling. Placing glass in a low-temperature chamber for low-temperature treatment is primarily to ensure temperature uniformity and stability, protect the glass surface, improve processing efficiency and product quality, and reduce safety risks.

[0004] In existing technologies, glass is placed in a low-temperature chamber for low-temperature treatment. However, glass usually lacks support and fixation functions. The lack of support and fixation may cause the glass to shift or shake during the treatment process, reducing processing accuracy and even increasing the scrap rate. At the same time, it is easy to increase the risk of glass breakage during handling. Therefore, a low-temperature glass treatment device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a glass cryogenic treatment device, which aims to improve the problem that existing glass cryogenic treatment devices lack support for the glass during cryogenic treatment, resulting in reduced treatment stability and treatment effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass low-temperature treatment device, including a mounting base, a low-temperature chamber fixedly connected to the top of the mounting base, a circulation pump fixedly connected to the inner wall of the low-temperature chamber via a pipe, an industrial chiller fixedly connected to the end of the circulation pump via a pipe, a placement platform provided inside the low-temperature chamber, a fixing frame fixedly connected to the top of the placement platform, a guide shaft rotatably connected to the inner surface of the fixing frame, a cylinder fixedly connected to the outer wall of the fixing frame, a clamping plate fixedly connected to the output end of the cylinder, a clearance groove penetrating the outer wall of the clamping plate, an installation frame provided inside the fixing frame, rollers rotatably connected to the inner surface of the installation frame, a support rod fixedly connected to the outer wall of the installation frame, a spring fixedly connected to the surface of the support rod, an installation groove penetrating the outer wall of the fixing frame, a gear rotatably connected to the inner wall of the installation groove, a driving rack fixedly connected to the outer wall of the clamping plate, and a driven rack fixedly connected to the outer wall of the installation frame.

[0010] The support rod is T-shaped and passes through the fixed frame and is slidably connected to the inner wall of the fixed frame.

[0011] As a further description of the above technical solution:

[0012] The clearance groove is fitted onto the outer wall of the mounting bracket, and the end of the spring is fixedly connected to the outer wall of the mounting bracket.

[0013] As a further description of the above technical solution:

[0014] The active rack meshes with the gear, the gear meshes with the passive rack, and the mounting slot is fitted onto the outer wall of the active rack and the passive rack.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the low-temperature greenhouse is fixedly connected to an air collection box. An air outlet is provided at the bottom of the air collection box. A valve is also fixedly connected to the inner wall of the top of the air collection box through a pipe. A delivery pipe is fixedly connected to the top of the valve, and an air pump is fixedly connected to the end of the delivery pipe.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this utility model, the glass is positioned by the guide shaft on the fixed frame, and the cylinder drives the clamping plate to clamp the glass from both sides.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figures 1-3This utility model provides an embodiment of a glass cryogenic treatment device, including a mounting base 1. A cryogenic chamber 2 is fixedly connected to the top of the mounting base 1, providing a stable support foundation for the entire device and ensuring that the cryogenic chamber 2 and other components are securely installed, reducing shaking during operation. The top of the cryogenic chamber 2 is equipped with several sets of low-vibration, low-noise fans, which are frequency-controlled and can be adjusted according to actual needs. This ensures temperature uniformity while reducing energy consumption. The low-vibration design avoids unnecessary vibration to the glass, the low noise improves the working environment, and the frequency conversion control flexibly adapts to the cryogenic treatment requirements of different types of glass. To ensure effective treatment while saving energy costs, a circulating pump 4 is fixedly connected to the inner wall of the low-temperature chamber 2 via pipes. An industrial chiller 3 is also fixedly connected to the end of the circulating pump 4 via pipes. The low-temperature chilled water generated by the industrial chiller 3 is directly introduced into the cooling equipment within the low-temperature chamber 2 through pipes, forming a highly efficient refrigeration cycle system. This system can quickly and continuously provide a stable low-temperature environment for the low-temperature chamber 2, ensuring that the temperature conditions for glass low-temperature treatment are accurately met. A placement platform 5 is installed inside the low-temperature chamber 2. The bottom of the placement platform 5 is equipped with casters connected to a track inside the low-temperature chamber 2, allowing the platform to be drawn from within the chamber. The placement platform 5 is designed for easy insertion and removal of glass from the low-temperature chamber 2 by staff, reducing operational difficulty and improving glass loading and unloading efficiency. A fixed frame 6 is fixedly connected to the top of the placement platform 5. The fixed frame 6 is arranged in a horizontal U-shape, with the U-shaped opening facing the entrance of the low-temperature chamber 2. Several sets of fixed frames 6 are evenly distributed on the placement platform 5 for placing glass. The U-shaped structure and evenly distributed design allow for orderly placement of glass, preventing mutual squeezing and collision. Multiple pieces of glass can be processed at once, improving processing efficiency. A guide shaft 7 is rotatably connected to the inner surface of the fixed frame 6. Multiple sets of guide shafts 7 guide the glass after it is placed inside the fixed frame 6. The shaft 7 rotates, reducing the friction between the glass and the fixing frame 6 during glass placement, making glass placement smoother and preventing scratches on the glass surface. A cylinder 8 is fixedly connected to the outer wall of the fixing frame 6, and a clamping plate 9 is fixedly connected to the output end of the cylinder 8. Two sets of cylinders 8 and clamping plates 9 are respectively provided to fix and clamp the glass on both sides. A clearance groove 10 is provided through the outer wall of the clamping plate 9. A clearance groove 10 is provided on both the left and right sides of each set of clamping plates 9 to provide space for the movement of the mounting frame 11, avoid interference between the clamping plate 9 and the mounting frame 11, and ensure the coordination of the operation of each component. The mounting frame 11 is provided inside the fixing frame 6.

[0038] Reference Figures 4-6The clearance groove 10 is fitted onto the outer wall of the mounting bracket 11. The mounting bracket 11 is U-shaped, which better adapts to the placement of the glass and provides a stable support structure for the installation of the rollers 12. Rollers 12 are rotatably connected to the inner surface of the mounting bracket 11. Multiple sets of rollers 12 are provided on each set of mounting brackets 11, rolling during glass extraction or insertion to further reduce friction during the glass extraction process, making glass insertion and removal easier and preventing damage to the glass surface. The rollers 12 and the guide shaft 7 are coated with polytetrafluoroethylene to reduce the coefficient of friction and prevent scratching the glass. A support rod 13 is fixedly connected to the outer wall of the mounting bracket 11. The support rod 13 is T-shaped and passes through the fixed frame 6, slidingly connecting with the inner wall of the fixed frame 6. Horizontal linear movement is achieved through the cooperation of the support rod 13 with the sliding groove on the inner wall of the fixed frame 6. The travel distance is limited by the length of the drive rack 16. The cooperation between the T-shaped support rod 13 and the sliding groove ensures the stability and linearity of the movement of the mounting bracket 11. The limitation of the travel distance prevents the mounting bracket 11 from moving excessively and affecting the operation of other components. A spring 14 is fixedly connected to the surface of the support rod 13. The spring 14 is made of INCONE. L718 nickel-based alloy ensures the stability of elastic modulus at -50℃. Spring 14 is used for auxiliary reset. The INCONEL 718 nickel-based alloy material can maintain good elasticity at low temperatures, ensuring that spring 14 can always play an effective auxiliary reset role during low-temperature treatment, ensuring the normal reset of mounting bracket 11. The end of spring 14 is fixedly connected to the outer wall of fixing bracket 6. The outer wall of fixing bracket 6 has a through mounting groove 15. The inner wall of mounting groove 15 is rotatably connected to gear 17. The outer wall of clamping plate 9 is fixedly connected to drive rack 16. The passive rack 18 is fixedly connected to the outer wall of the mounting bracket 11 in contact with the gear 17. The gear 17 meshes with the passive rack 18. The mounting through groove 15 is fitted on the outer wall of the active rack 16 and the passive rack 18. When the two sets of clamps 9 approach each other, the active rack 16 drives the passive rack 18 to move outward to both sides of the fixed bracket 6 through meshing with the gear 17, so that the mounting bracket 11 is retracted. Conversely, when the two sets of mounting brackets 11 approach each other, the roller 12 contacts the glass surface. The cylinder 8 and the gear 17 use cold-resistant sealing rings made of fluororubber FKM, which is resistant to temperatures of -40℃ to prevent low-temperature embrittlement.

[0039] Reference Figures 1-3An air collection box 19 is fixedly connected to the inner wall of the low-temperature chamber 2. The air collection box 19 extends through the top of the low-temperature chamber 2 and is used to centrally transport and distribute low-temperature air, providing a stable airflow source for forming an air curtain. The air collection box 19 is located at the inlet of the low-temperature chamber 2. Several sets of air outlets 20 are provided at the bottom of the air collection box 19, and these sets are evenly distributed at the bottom. The evenly distributed air outlets 20 ensure a more uniform airflow, guaranteeing the integrity and stability of the air curtain. A valve 22 is also fixedly connected to the inner wall of the top of the air collection box 19 via a pipe. A conveying pipe 21 is fixedly connected to the top of the valve 22 for transporting... Pipe 21 is a T-junction, and each set of pipes penetrates into the inner wall of the delivery pipe 21, introducing air into the air collection box 19. The T-junction design enables air diversion and delivery. Valve 22 can precisely control the air flow entering the air collection box 19 to meet the needs of different working conditions. An air pump 23 is fixedly connected to the end of the delivery pipe 21. The outer wall of the air pump 23 is fixedly connected to the top of the low-temperature chamber 2. The input end of the air pump 23 is also fixedly connected to the inner wall of the low-temperature chamber 2 through a pipe. The air inlet of the air pump 23 is connected to the circulating air duct inside the low-temperature chamber 2. The extracted low-temperature air is delivered to the air collection box 19 through the delivery pipe 21, and the flow rate is throttled to 0.5-1.2m through valve 22. 3 / min, and finally sprayed downwards from the evenly distributed air outlets 20 at a wind speed of ≥3m / s, forming a low-temperature air curtain. The low-temperature air curtain can effectively block the entry of hot air from outside the low-temperature chamber 2, reduce the loss of cold air inside the low-temperature chamber 2, maintain the stability of the internal temperature of the low-temperature chamber 2, and reduce energy consumption.

[0040] Working Principle: After the equipment starts, the industrial chiller 3 generates low-temperature chilled water. Under the action of the circulating pump 4, the low-temperature chilled water is introduced into the cooling equipment in the low-temperature chamber 2 through pipelines. At the same time, the variable frequency fan on the top of the low-temperature chamber 2 starts and adjusts its speed according to actual needs to ensure uniform temperature in the low-temperature chamber 2 and reduce energy consumption, thereby creating a stable low-temperature processing environment. When placing the glass, the placement platform 5 with rotating wheels can be pulled out from the low-temperature chamber 2 along the track. The glass is placed using the U-shaped opening of the fixing frame 6. During the glass placement process, the guide shaft 7 on the inner surface of the fixing frame 6 rotates accordingly, reducing friction between the glass and the fixing frame 6 and assisting the glass to enter smoothly. When the glass is in place, when the cylinder 8 pushes the clamping plate 9 to move towards the glass, the active rack 16 fixed to the side wall of the clamping plate 9 moves forward horizontally, driving the gear 17 meshing with it to rotate counterclockwise; the gear 17 drives the passive rack meshing with it. The horizontal outward movement of the passive rack 18 is opposite to the movement of the active rack 16. The passive rack 18 forces the roller 12 to retract into the clearance groove 10 through the mounting bracket 11. When the cylinder 8 retracts, the active rack 16 moves backward, the gear 17 rotates clockwise, and the passive rack 18 drives the mounting bracket 11 to reset towards the glass, so that the roller 12 protrudes from the inner surface of the fixed bracket 6 and contacts the glass. This, combined with the guide shaft 7, facilitates the removal of the glass. In addition, the spring 14 on the support rod 13 can act as a buffer when the mounting bracket 11 moves. During the process, the air pump 23 draws air and sends it into the air collection box 19 through the delivery pipe 21 and valve 22. Finally, it is sprayed out through the air outlet 20 at the bottom, forming an air curtain at the inlet of the low temperature chamber 2, reducing the air exchange between the inside and outside of the low temperature chamber 2, and maintaining the stable low temperature inside. After the process is completed, the placement platform 5 is pushed into the low temperature chamber 2 along the track to complete the entire glass low temperature treatment process.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
