Special glass annealing equipment

Abstract

The application discloses a special glass annealing processing equipment and relates to the technical field of glass processing. The special position flexible change structure is adopted in the application, and the contact roller is endowed with the reciprocating rolling property in the annealing operation process. On the one hand, the symmetrical rolling is less harmful to the glass, and the reaction force is symmetrical and relatively stable (although only one set of rollers is arranged on the back side of the front and rear sides of the box body, the force cannot be corresponded, but the glass cannot effectively displace due to the space limitation of the box body, and the glass is also in a stable state), and on the other hand, the contact area between the glass and the lower rollers in the annealing operation in the annealing box changes dynamically at any time, so that the problem of the large temperature difference of the force points can be fundamentally relieved. In addition, the dynamic change mode of the rolling walking has little damage to the glass, and is worthy of being popularized in the processing of high-standard glass pieces used in special environments and conditions.

Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to a special glass annealing processing equipment. Background Technology

[0002] Glass annealing refers to the process of eliminating or reducing the internal stress generated in glass during manufacturing through special heat treatment processes. Its main purpose is to improve the stability and performance of glass. On the one hand, it eliminates residual stress: permanent thermal stress is generated in glass during forming or hot processing due to uneven temperature. Annealing reduces or eliminates these stresses by controlling the heating and cooling process, thus preventing glass from cracking or degrading its performance. On the other hand, it improves optical uniformity: annealing can reduce the optical non-uniformity inside the glass, thereby improving transparency and optical performance.

[0003] Especially for special glass used for special purposes or in extreme situations, the requirements and indicators for annealing are more stringent in order to achieve higher overall performance. Special glass is usually produced using processes such as rolling and float glass, which are more suitable for producing large-area, uniformly thick flat glass.

[0004] Due to the limitations of existing glass annealing processes and equipment, flat glass from the same batch is often placed in layers and then heat-treated uniformly in the annealing chamber. To ensure uniform heating between adjacent glass pieces, a gasket is added between the two adjacent pieces. However, during annealing, the chemical components in the raw materials of the glass undergo decomposition reactions, releasing various gases (carbon dioxide, sulfur dioxide, etc.). Although existing annealing chambers are equipped with hot air circulation systems, these hot and humid gases accumulate in the relatively narrow gaps between adjacent glass pieces. Because there is a lack of gas flow at the center of the gap, the hot and humid gases at the center of the gap have difficulty participating in the hot air circulation system, thus causing uneven heating on the inside and outside of the glass.

[0005] Furthermore, there has always been an objective problem in the batch annealing of glass: glass generally needs to be supported at multiple points during annealing. However, there will always be a temperature difference between the contact area covered by the support points and other exposed areas of the glass, especially in annealing chambers where the temperature can reach several hundred degrees Celsius, which can cause a temperature difference of tens of degrees. Excessive temperature difference will increase the glass cracking rate. At present, the industry mostly uses methods such as reducing the area of ​​the glass support points or placing the glass vertically to make the glass edges contact each other to alleviate and reduce the impact of the temperature difference problem at the support points, but these are all temporary solutions.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing special glass annealing processing equipment. Summary of the Invention

[0007] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the invention aims to provide a special glass annealing processing equipment to solve the problem mentioned in the background art where the chemical components in the raw materials of glass undergo decomposition reactions during annealing, releasing various gases (carbon dioxide, sulfur dioxide, etc.). Although existing annealing chambers are equipped with hot air circulation systems, these hot and humid gases tend to accumulate in the relatively narrow gaps between adjacent glass panes. Due to the lack of gas flow at the center of the gap, the hot and humid gases at the center of the gap have difficulty participating in the hot air circulation system, thus causing uneven heating of the inner and outer sides of the glass.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a special glass annealing processing equipment, including an annealing box and a servo motor and a sprocket transmission box disposed on the back side of the annealing box, and further including a number of rollers evenly distributed in a stacked manner inside the annealing box for supporting the glass, a spiral shifter driven to rotate by the sprocket transmission box and capable of changing the contact position between the rollers and the glass at any time, and a lead screw connected to the spiral shifter;

[0009] The external configuration of the lead screw is a walking dehumidification mechanism that accelerates the discharge of hot and humid air between the glass panes by adjusting the opening and closing angle.

[0010] The walking dehumidification mechanism includes a wind vane that is driven by a lead screw to move back and forth, and guide rails symmetrically installed on both sides of the lead screw to control the opening and closing angle of the wind vane.

[0011] The internal components of several lead screws in the middle of each glass layer are connected by a bevel gear set.

[0012] Preferably, three rollers, three spiral shifters, and three sets of walking dehumidification mechanisms are evenly arranged between two adjacent glass pieces;

[0013] Several of the aforementioned spiral shifters near the back of the annealing box are fixedly connected to several output shafts on the sprocket drive box through bearings to form a drive structure;

[0014] Several of the aforementioned spiral shifters, located near the side wall of the annealing chamber, are rotatably mounted on the inner wall of the annealing chamber.

[0015] Preferably, the helical shifter is made of a rigid material, and the helical shifter and the lead screw are coaxially arranged;

[0016] The end of the spiral shifter is fixedly connected to the end of the lead screw.

[0017] Preferably, the outer wall of the spiral shifter is provided with a sliding sleeve, and the lower end of the roller is fixedly connected to the sliding sleeve.

[0018] Preferably, a fixing rod fixed to the inner wall of the annealing chamber is provided between two adjacent glass pieces;

[0019] The lower end of the roller is slidably connected to the fixed frame rod to support the horizontal linear movement of the roller;

[0020] The end of the fixed frame rod is fixed with a square frame, and the bevel gear set is evenly installed inside the square frame.

[0021] Preferably, the walking dehumidification mechanism further includes a sliding plate sleeved on the outer wall of the lead screw thread, and the sliding plate has a screw hole inside that matches the thread of the lead screw outer wall;

[0022] The sliding plate is fitted onto the outer wall of the end of the fixed frame rod to form a sliding connection.

[0023] Preferably, the wind vane is symmetrically arranged at the upper and lower ends of the slide plate and is rotatably connected to both the upper and lower ends of the slide plate.

[0024] Preferably, a guide rod is hinged to the side wall of the wind vane away from the end of the slide plate, and the guide rail is symmetrically arranged about the central axis of the slide plate;

[0025] The guide rail has a groove inside, and the guide rod is slidably disposed inside the groove.

[0026] Preferably, the track groove consists of four parts: an outer straight track close to the slide plate, an inner straight track away from the slide plate, and two transition tracks connecting the inner and outer straight tracks;

[0027] The transition track away from the helical shifter is curved to ensure a smooth transition;

[0028] The transition track near the helical shifter consists of two parts: an arc track and a straight track, used for smooth transition and anti-return transition, respectively.

[0029] When the guide rod is located inside the inner straight track, the wind vane is in a tightened state;

[0030] When the guide rod is located inside the outer straight track, the wind vane is in an expanded state.

[0031] Preferably, tension springs are symmetrically arranged between two adjacent air vanes about the central axis of the lead screw to cooperate with the two transition tracks to realize the track switching of the guide rod;

[0032] The two ends of the tension spring are respectively welded to the opposite sides of the two wind plates.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. This invention employs a unique, flexibly changing structure, which endows the contact rollers with reciprocating rolling properties during the annealing process. On the one hand, the symmetrical rolling reduces damage to the glass, and the symmetrical reaction force makes the glass relatively stable (although only one set of rollers is set on the back side of the front and rear sides of the chamber, the forces cannot correspond, but due to the space limitation of the chamber, the glass cannot undergo effective displacement, which is also a stable state). On the other hand, the contact area between the glass and the rollers below during the annealing process in the annealing chamber changes dynamically at all times, which can fundamentally alleviate the problem of large temperature differences at the point of force application. Moreover, the dynamic rolling movement method causes almost no damage to the glass, making it worthy of promotion and use in the processing of high-standard glass parts used in special environments and conditions.

[0035] 2. Based on effect 1, this invention simultaneously sets up a walking dehumidification mechanism that can move back and forth in the glass gap with the rollers. When the slide moves from the edge of the glass to the center of the glass, the wind plates on both sides are in a "wind-breaking" state with a relatively small angle. When the slide moves from the center of the glass to the edge of the glass, the wind plates on both sides will dynamically and stably change to a "wind-pushing" state with a relatively large angle under the guidance and drive of the guide rail. This generates a pushing effect from the center outward, thereby pushing out the hot and humid air that is sluggish and continuously generated in the glass gap. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figures 1 to 10 The present invention provides a technical solution: a special glass annealing processing equipment, including an annealing box 1 and a servo motor 2 and a sprocket transmission box 21 disposed on the back side of the annealing box 1, and also including a plurality of rollers 41 evenly distributed in a stacked manner inside the annealing box 1 for supporting the glass, a spiral shifter 3 driven to rotate by the sprocket transmission box 21 and capable of changing the contact position between the rollers 41 and the glass at any time, and a lead screw 31 connected to the spiral shifter 3;

[0049] The external setting of the lead screw 31 is a walking dehumidification mechanism that accelerates the discharge of hot and humid air between the glass by adjusting the opening and closing angle.

[0050] The walking dehumidification mechanism includes a wind vane 6 that is driven by a lead screw 31 to move back and forth, and guide rails 7 that are symmetrically installed on both sides of the lead screw 31 to control the opening and closing angle of the wind vane 6.

[0051] The internal components of several lead screws 31 in the middle of each glass layer are connected by a bevel gear set 33.

[0052] As an optional embodiment, in this embodiment, a total of four sets of bevel gear sets 33 are provided. The bevel gears near the door of the annealing box 1 are empty and are only used to form a stable closed-loop transmission, while the set of bevel gears facing the back of the annealing box 1 are the drive gears, and three bevel gears are respectively connected to three lead screws 31.

[0053] Three sets of rollers 41 evenly distributed at the bottom of each glass layer provide stable support. There is no need to install excessive rollers 41 on the side near the door. Moreover, due to the space limitation inside the annealing chamber 1, three sets of rollers 41 are sufficient to provide stable support for the glass.

[0054] Three rollers 41, three spiral shifters 3, and three sets of walking dehumidification mechanisms are evenly arranged between two adjacent glass panes;

[0055] Several spiral shifters 3 near the back of the annealing box 1 are fixedly connected to several output shafts on the sprocket drive box 21 through bearings to form a drive structure.

[0056] Several spiral shifters 3 near the side wall of the annealing chamber 1 are rotatably installed on the inner wall of the annealing chamber 1.

[0057] As an optional embodiment, the sprocket drive box 21 has multiple output shafts on the side near the annealing box 1 from top to bottom, and each output shaft is poweredly connected to a set of spiral shifters 3 in each layer for driving. The sprocket drive box 21 can also be replaced by other multi-axis transmission methods.

[0058] The screw shifter 3 is made of rigid material, and the screw shifter 3 and the lead screw 31 are coaxially arranged;

[0059] The end of the spiral shifter 3 is fixedly connected to the end of the lead screw 31.

[0060] As an optional embodiment, the spiral shifter 3 is uniformly spiral in shape, and the spiral shifter 3 is made of a hard metal material that is not easily deformed. At the same time, the surface of the spiral shifter 3 is smoothed to reduce the frictional resistance and wear between the sliding sleeve 4 and the spiral shifter 3.

[0061] The outer wall of the spiral shifter 3 is fitted with a sliding sleeve 4, and the lower end of the roller 41 is fixedly connected to the sliding sleeve 4.

[0062] A fixing rod 42, which is fixed to the inner wall of the annealing chamber 1, is provided between two adjacent pieces of glass;

[0063] The lower end of the roller 41 is slidably connected to the fixed frame rod 42 to support the horizontal linear movement of the roller 41;

[0064] A square frame 32 is fixed to the end of the fixed bracket 42, and the bevel gear set 33 is evenly installed inside the square frame 32.

[0065] As an optional embodiment, when the spiral shifter 3 is driven by the servo motor 2 and the sprocket transmission box 21 to rotate alternately in the forward and reverse directions, the rotating spiral shifter 3 will have a rotational following effect on the sliding sleeve 4. However, since the sliding sleeve 4 is subject to the horizontal limiting and guiding effect of the fixed frame rod 42, the spiral shifter 3 will drive the sliding sleeve 4 to move horizontally and linearly along the outer wall of the fixed frame rod 42 when rotating, and meet the torsional requirements of the spiral shifter 3.

[0066] When the spiral shifter 3 rotates in the forward direction, the sliding sleeve 4 carries the roller 41 from the outer end of the spiral shifter 3 to the inner end of the spiral shifter 3. When it moves horizontally to the inner end of the spiral shifter 3, the servo motor 2 reverses and drives the spiral shifter 3 to rotate in the opposite direction. Similarly, the sliding sleeve 4 carries the roller 41 from the inner end of the spiral shifter 3 to the outer end of the spiral shifter 3, thereby realizing the reciprocating linear horizontal movement of the roller 41.

[0067] The upper end of the roller 41 makes rolling contact with the lower surface of the glass. When the roller 41 moves horizontally in a straight line, its position changes constantly along the lower surface of the glass. On the one hand, the symmetrical rolling reduces damage to the glass, and the symmetrical reaction force makes the glass relatively stable (although only one set of rollers 41 is set on the back side of the front and rear sides of the chamber, the forces cannot correspond, but due to the space limitation of the chamber, the glass cannot make effective displacement, which is also a stable state). On the other hand, the contact area between the glass undergoing annealing in the annealing chamber 1 and the lower roller 41 changes dynamically at all times, which can fundamentally alleviate the problem of large temperature difference at the point of force application. Moreover, the dynamic change method of rolling movement causes almost no damage to the glass, which is worth promoting in the processing of high-standard glass parts used in special environments and conditions.

[0068] The walking dehumidification mechanism also includes a slide plate 5 fitted onto the threaded outer wall of the lead screw 31, and the slide plate 5 has a screw hole inside that matches the thread of the outer wall of the lead screw 31.

[0069] The sliding plate 5 is fitted onto the outer wall of the end of the fixed frame rod 42 to form a sliding connection.

[0070] As an optional embodiment, the lead screw 31 is coaxially arranged with the helical shifter 3. When the helical shifter 3 rotates, the lead screw 31 can rotate synchronously and drive the slide plate 5 to move horizontally and linearly on the outer wall of the fixed frame rod 42.

[0071] It is particularly important to note that since the three sets of lead screws 31 are linked by a bevel gear set 33, and the bevel gear set 33 involves a change in direction, this can be accomplished by designing the corresponding helical direction of the lead screws 31 in the actual design. This is a relatively conventional helical orientation improvement design, so this invention will not elaborate on it. Ultimately, it is only necessary to ensure that when the three sets of rollers 41 move inward synchronously, the three sets of sliding plates 5 will also move inward synchronously, and when the three sets of rollers 41 move outward synchronously, the three sets of sliding plates 5 will also move outward synchronously.

[0072] The wind plate 6 is symmetrically arranged at the upper and lower ends of the slide plate 5 and is rotatably connected to both the upper and lower ends of the slide plate 5.

[0073] A guide rod 61 is hinged to the side wall of the wind plate 6 away from the end of the slide plate 5, and the guide rail 7 is symmetrically arranged about the central axis of the slide plate 5.

[0074] The guide rail 7 has a track groove 71 inside, and the guide rod 61 is slidably disposed inside the track groove 71.

[0075] The track groove 71 consists of four parts: an outer straight track close to the slide plate 5, an inner straight track away from the slide plate 5, and two transition tracks connecting the inner and outer straight tracks;

[0076] The transition track away from the spiral shifter 3 is arc-shaped to ensure a smooth transition;

[0077] The transition track near the spiral shifter 3 consists of two parts: an arc track and a straight track, which are used for smooth transition and anti-return transition, respectively.

[0078] When the guide rod 61 is located inside the inner straight track, the wind vane 6 is in a tightened state;

[0079] When the guide rod 61 is located inside the outer straight track, the wind vane 6 is in an expanded state.

[0080] As an optional embodiment, when the slide plate 5 moves horizontally inward driven by the screw 31, the slide plate 5 will simultaneously pull the two air plates 6 at the upper and lower ends to move inward synchronously. The air plates 6 that move inward synchronously are symmetrically provided with guide rods 61 that slide on the inner straight track. When the guide rods 61 move from the inner straight track to the transition track away from the spiral shifter 3, since the tension spring 62 is in a compressed state at this time, as the air plates 6 continue to move inward and under the expansion action of the tension spring 62, the two air plates 6 will gradually expand and adapt to the arc of the transition track away from the spiral shifter 3. When the guide rods 61 move and expand to the top of the transition track away from the spiral shifter 3, the servo motor 2 just reverses and drives the slide plate 5 to expand outward. At this time, the slide plate 5 will generate a stable outward pushing force on the guide rods 61 through the air plates 6, so that the guide rods 61 fall stably into the outer straight track. Thus, during the outward return movement of the slide plate 5, the two air plates 6 are in a stable open state.

[0081] Subsequently, when the guide rod 61 falls from the outer straight track into the transition track near the spiral shifter 3, the wind vane 6 will gradually change from an expanding state to a retracted state under the arc-shaped guiding action of the arc-shaped track on the guide rod 61. When the guide rod 61 falls exactly at the intersection of the arc-shaped track and the straight track, the servo motor 2 reverses again and drives the slide plate 5 to move inward quickly, so that the guide rod 61 quickly transitions into the straight track to prevent the guide rod 61 from returning to the outer straight track along the arc-shaped track due to the reset thrust of the tension spring 62. Then the guide rod 61 will continue to move inward along the inner straight track, and so on.

[0082] The overall effect is as follows: when the slide plate 5 moves from the edge of the glass to the center of the glass, the wind plates 6 on both sides are in a "wind-breaking" state with a relatively small angle. When the slide plate 5 moves from the center of the glass to the edge of the glass, the wind plates 6 on both sides will dynamically and stably change to a "wind-pushing" state with a relatively large angle under the guidance and drive of the guide rail 7. This will generate a pushing effect from the center outward, thereby pushing out the hot and humid air that is sluggish and continuously generated in the gap between the glass.

[0083] A tension spring 62 is symmetrically arranged between two adjacent air vanes 6 about the central axis of the lead screw 31 to cooperate with the two transition tracks to realize the track switching of the guide rod 61;

[0084] The two ends of the tension spring 62 are welded to the opposite sides of the two wind plates 6 respectively.

[0085] Working principle: When using this special glass annealing processing equipment, firstly as follows... Figures 1 to 4 As shown, the glass is pushed into the annealing chamber 1 in sequence and placed on the corresponding three sets of rollers 41. The gap between each set of glass is relatively small and the spacing is the same. Then the chamber door is closed to carry out the annealing operation.

[0086] When the servo motor 2 is started, the driving force of the servo motor 2 is evenly distributed to the outer end of each output type of spiral shifter 3 by the sprocket transmission box 21. When the spiral shifter 3 is driven by the servo motor 2 and the sprocket transmission box 21 to rotate alternately in the forward and reverse directions, the rotating spiral shifter 3 will have a rotational following effect on the sliding sleeve 4. However, since the sliding sleeve 4 is subject to the horizontal limiting and guiding effect of the fixed frame rod 42, the spiral shifter 3 will drive the sliding sleeve 4 to move horizontally and linearly along the outer wall of the fixed frame rod 42 when it rotates, and meet the torsional requirements of the spiral shifter 3. When the spiral shifter 3 rotates in the forward direction, the sliding sleeve 4 will carry the roller 41 from the outer end of the spiral shifter 3 to the inner end of the spiral shifter 3. When it moves horizontally to the inner end of the spiral shifter 3, the servo motor 2 reverses and drives the spiral shifter 3 to rotate in the reverse direction. Similarly, the sliding sleeve 4 carries the roller 41 from the inner end of the spiral shifter 3 to the outer end of the spiral shifter 3, thereby realizing the reciprocating linear horizontal movement of the roller 41.

[0087] Meanwhile, since the upper end of the roller 41 is in rolling contact with the lower surface of the glass, when the roller 41 moves horizontally in a straight line, the roller 41 will constantly change position along the lower surface of the glass. On the one hand, the symmetrical rolling causes less damage to the glass and the reaction force is symmetrical, making the glass relatively stable (although only one set of rollers 41 is set on the back side of the front and rear sides of the chamber, the force cannot be corresponding, but due to the space limitation of the chamber, the glass cannot be effectively displaced, which is also a stable state). On the other hand, the contact area between the glass undergoing annealing in the annealing chamber 1 and the lower roller 41 will change dynamically at all times, which can fundamentally alleviate the problem of large temperature difference at the point of force application. Moreover, the dynamic change method of rolling movement causes almost no damage to the glass, which is worth promoting and using in the processing of high-standard glass parts used in special environments and conditions.

[0088] At the same time, the spiral shifter 3 will synchronously drive the lead screw 31 to rotate. When the slide plate 5 moves horizontally inward driven by the screw 31, the slide plate 5 will synchronously pull the two air plates 6 at the upper and lower ends to move inward. The air plates 6 that move inward synchronously are symmetrically provided with guide rods 61 that slide on the inner straight track. When the guide rods 61 move from the inner straight track to the transition track away from the spiral shifter 3, since the tension spring 62 is in a compressed state at this time, as the air plates 6 continue to move inward and under the expansion action of the tension spring 62, the two air plates 6 will gradually expand and adapt to the arc of the transition track away from the spiral shifter 3. When the guide rods 61 move and expand to the top of the transition track away from the spiral shifter 3, the servo motor 2 just reverses and drives the slide plate 5 to expand outward. At this time, the slide plate 5 will generate a stable outward pushing force on the guide rods 61 through the air plates 6, so that the guide rods 61 fall stably into the outer straight track. Thus, during the outward return movement of the slide plate 5, the two air plates 6 are in a stable open state.

[0089] Subsequently, when the guide rod 61 falls from the outer straight track into the transition track near the helical shifter 3, the air deflector 6 will gradually change from an expanding state to a retracted state under the arc-shaped guiding action of the arc-shaped track on the guide rod 61. When the guide rod 61 lands exactly at the intersection of the arc-shaped track and the straight track, the servo motor 2 reverses again, driving the slide plate 5 to move rapidly inward, thus allowing the guide rod 61 to quickly transition into the straight track. This prevents the guide rod 61 from returning to the outer straight track along the arc-shaped track due to the reset thrust of the tension spring 62. Subsequently, the guide rod 61 will continue to move inward along the inner straight track. The effect achieved by this cycle is as follows: when the slide plate 5 moves from the edge of the glass to the center of the glass, the wind plates 6 on both sides are in a "wind-breaking" state with a relatively small angle. When the slide plate 5 moves from the center of the glass to the edge of the glass, the wind plates 6 on both sides will dynamically and stably change to a "wind-pushing" state with a relatively large angle under the guidance and drive of the guide rail 7. This will generate a pushing effect from the center outward, thereby pushing out the hot and humid air that is sluggish and continuously generated in the gap between the glass.
