Description

[0002] In the prior art, conventional roller-type forming and tempering equipment is usually provided with forming and blowing mechanisms on the upper and lower sides of the glass. The upper and lower forming and blowing mechanisms can be raised and lowered to move away from or close to the glass surface. After the cylindrical glass with a central angle of the large opening less than or equal to 180° is formed and tempered, Fig.12 Because the opening is large, the upper side of the forming and blowing mechanism is moved away from the cylindrical glass by lifting from the cylindrical opening of the cylindrical glass, and further separated from the cylindrical glass. However, the device cannot form cylindrical glass with a small opening. For cylindrical glass with a central angle greater than 180°, such as Fig.13 The opening of the glass cylinder is smaller than the maximum distance between any two points on its cross section. After the upper forming and blowing mechanism forms and blows air on the inner surface of the glass, it cannot move away from the columnar glass from the cylinder opening, and thus cannot separate from the glass.

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0058] Example 1: Figure 1 , 2 As shown, a columnar glass forming and tempering integrated device includes an inner forming air blowing mechanism 2, an outer forming air blowing mechanism 3 and a moving mechanism; the inner forming air blowing mechanism 2 includes a columnar wind grid and a roller assembly, and the roller assembly is arranged on the outer side of the cylindrical surface of the columnar wind grid; the moving mechanism can drive the inner air blowing mechanism to move along the generatrix direction of the columnar glass to realize the separation of the inner air blowing forming mechanism from the columnar tempered glass.

[0059] The columnar wind grid is provided with a plurality of blowing ports connected with the cold air channel, and the plurality of blowing ports form a columnar inner blowing surface adapted to the shape of the inner surface of the target columnar glass; the roller assembly is arranged on the outer side of the columnar wind grid, and can be fitted into a columnar inner molding surface that matches the shape of the inner surface of the target columnar glass, which is used for glass molding, and can make the arrangement of the columnar inner molding surface and the columnar inner blowing surface more reasonable, the molding process and the blowing process do not interfere with each other, and the quality of the produced columnar tempered glass is better.

[0060] In this embodiment, the roller assembly includes a plurality of rollers arranged at intervals along the circumferential direction of the outer side of the cylindrical surface of the columnar wind grid, and the plurality of rollers are fitted into the cylindrical inner molding surface, the central angle of the cylindrical inner molding surface is greater than 180°, and the length direction of the rollers is parallel to the generatrix direction of the cylindrical inner molding surface, and the rollers are hard shaft rollers or soft shaft rollers.

[0061] Alternatively, the roller assembly includes a plurality of rollers arranged on a columnar wind grid, the plurality of rollers are fitted to form the columnar inner molding surface, and the generatrix direction of the rollers is parallel to the generatrix direction of the columnar inner molding surface.

[0062] In the integrated forming and tempering device, the outer forming and blowing mechanism 3 can form an outer cylindrical forming surface that matches the shape of the outer surface of the target columnar glass, and is used to cooperate with the inner cylindrical forming surface to form the columnar glass; the inner forming and blowing mechanism 2 can cooperate with the outer forming and blowing mechanism 3 through the roller assembly on the outer side of the columnar wind grid to form the glass into a columnar shape, and then the columnar wind grid and the outer forming and blowing mechanism are used to blow the glass into a columnar shape to achieve the columnar forming and blowing tempering of the glass. After the forming and tempering of the glass is completed, the moving mechanism can drive the inner forming and blowing mechanism 2 to move out along the generatrix direction of the columnar glass to separate the columnar glass with a small opening. The integrated forming and tempering device of this embodiment can achieve the forming, tempering and stripping of columnar glass with a small opening, and can also achieve the forming, tempering and stripping of columnar glass with a large opening.

[0063] The central angle of the cylindrical glass is based on the shape of a cross section of the cylindrical glass. The angle enclosed by its shape is as follows: Fig.12 , Fig.13 As shown, the central angles thereof are respectively less than 180° and greater than 180°.

[0064] Embodiment 2: Based on embodiment 1, Figures 3 to 7 As shown, the columnar wind grid is a columnar cylinder structure 201, the roller assembly is arranged on the outside of the columnar cylinder structure 201, and is fitted into a columnar inner molding surface 204 that matches the shape of the inner surface of the target columnar glass. The air inlet of the columnar cylinder structure 201 is arranged at the outer end of its generatrix direction, and a plurality of cold air channels are arranged inside the columnar cylinder structure along its generatrix direction. The columnar cylinder structure 201 is provided with a plurality of blowing ports connected to the cold air channels, and the plurality of blowing ports form a columnar inner blowing surface that matches the shape of the inner surface of the target columnar glass; the blowing ports are blowing holes. The columnar cylinder structure can smoothly complete the blowing tempering and separation of small-opening columnar glass. The air inlet is arranged at the outer end of its generatrix direction, and the air inlet is smoother. The design of the columnar inner blowing surface allows the glass to be more evenly exposed to the wind, and the glass tempering quality is better, and the separation from the columnar glass is also smoother.

[0065] The roller assembly includes a plurality of hard-shaft rollers 202 arranged at intervals along the circumferential direction of the outer surface of the cylindrical barrel structure 201, and the length direction of the rollers is arranged parallel to the generatrix direction of the cylindrical barrel structure 201. The hard-shaft rollers 202 are arranged on the cylindrical barrel structure 201 through a support seat 203. The plurality of hard-shaft rollers 202 are fitted into a cylindrical inner molding surface 204 that matches the shape of the inner surface of the target glass. Figure 4 As shown, it is convenient to form, making the setting and selection of the columnar inner forming surface more flexible, the columnar inner forming surface is easier to adjust, and the columnar barrel structure 201 makes the fixation of the hard shaft roller more convenient.

[0066] In addition, further, in other embodiments, after the glass is formed on the internal forming and blowing mechanism 2, the columnar glass can be rotated and swung around the roller assembly to be exposed to the wind, thereby achieving a better glass tempering effect.

[0067] In other embodiments, further, the conveying direction of the glass entering the columnar glass forming and tempering integrated device is perpendicular to the generatrix direction of the columnar barrel structure 201, so that the continuity of glass production is better.

[0068] It also includes a fan, which is connected to the air inlet of the columnar barrel structure 201. The moving mechanism includes a moving slide. The inner forming air blowing mechanism 2 and the fan are both arranged on the moving slide. The sliding direction of the moving slide is parallel to the generatrix direction of the columnar glass. A plurality of blowing holes are evenly distributed on the circumferential surface of the columnar barrel structure 201. The plurality of blowing holes are located between adjacent hard shaft rollers 202. One end of the columnar barrel structure 201 is closed, and the other end is fixed on a fixed frame and connected to the fan. The fan supplies air to the columnar barrel structure 201 to blow and temper the inner surface of the target glass. The moving mechanism can drive the inner forming air blowing mechanism 2 to move along the generatrix direction of the columnar glass to achieve the separation of the inner blowing molding mechanism 2 from the columnar tempered glass.

[0069] like Figure 3 In this embodiment, two inner forming air blowing mechanisms 2 are arranged. The columnar barrel structures 201 of the two mechanisms have the same diameter specification and are coaxially arranged. The two inner forming air blowing mechanisms 2 and the connected left-side fan 6 and right-side fan 9 are arranged on the left-side movable slide 5 and the right-side movable slide 8 on the left and right sides of the frame 1. The left-side movable slide 5 is slidably arranged on the left-side ground rail 7, and the right-side movable slide 8 is slidably arranged on the right-side ground rail 10. This arrangement can realize the molding of larger-sized glass, especially the molding of larger-sized glass in its busbar direction. When detaching from the glass, the two inner forming air blowing mechanisms 2 move away from each other along the busbar direction of the columnar glass to achieve detachment from the columnar glass.

[0070] like Figure 5 , 6 As shown, taking the left inner molding air blowing mechanism 2 as an example, during the glass forming process, the left movable slide 5 is located at the right end of the left ground rail 7. Similarly, the right movable slide 8 is located at the left end of the right ground rail 10. The closed ends of the columnar barrel structures 201 of the two inner molding air blowing mechanisms 2 are butted together to meet the requirements of the glass width; the formed columnar glass will be wound on the roller assembly on the outside of the columnar barrel structure 201, especially the columnar glass with a central angle greater than 180°, the opening on the glass column is smaller than the diameter of the columnar barrel structure 201, so it is difficult to remove the columnar barrel structure 201 from the opening of the columnar glass. At this time, the left and right movable slides can be slid to move the columnar barrel structures 201 on the left and right sides out from the ends of the formed glass, thereby achieving separation from the glass.

[0071] In the above embodiment, the columnar wind grille used for blowing air to the inner surface of the glass adopts the columnar cylinder structure 201, which is a cylindrical cylinder as a whole. Figure 4 In other embodiments, other shapes of cylindrical barrel structures can be selected according to the shape of the target glass, such as a semi-cylindrical barrel with a central angle of α, 180°<α<360°, or Figure 7 The elliptical cylinder 205 shown can also be a semi-elliptical cylinder with a central angle of α, 180°<α<360°. In the specific selection of α, it is sufficient to satisfy that α is greater than the central angle of the target glass cylinder. The above structure can make the fixation of the roller assembly more convenient, the molding of the cylindrical inner molding surface is also easier, and the structure of the columnar wind grille is more preferred. In addition, preferably, the columnar cylinder structure is an integrated structure, which is more practical, durable and stable.

[0072] Preferably, in the present embodiment, a transmission gear 11 is also installed at the end of the hard shaft roller 202 of the inner forming air blowing mechanism 2, and a roller drive motor 12 is arranged on the fixed frame. The roller drive motor 12 drives the hard shaft roller 202 to rotate actively through the cooperation of the chain and the transmission gear 11, and cooperates with the conveying roller of the outer forming air blowing mechanism 3 to drive the glass to rotate and swing between the outer forming air blowing mechanism 3 and the inner forming air blowing mechanism 2.

[0073] In the present embodiment, two coaxially arranged internal molding air blowing mechanisms 2 are used. In other embodiments, only one internal molding air blowing mechanism 2 may be used. In this case, one end of the internal molding air blowing mechanism 2 is connected to the corresponding movable slide, and the whole is in a suspended state. The size of the internal molding air blowing mechanism 2 along the busbar direction of the columnar glass is set too large. Long-term use of the internal molding air blowing mechanism 2 will cause it to sag and deform due to its center of gravity offset and the weight of the glass. Therefore, it is more suitable for smaller glass molding. When the size of the glass along the busbar direction of the columnar glass is large, it is necessary to use two internal molding air blowing mechanisms 2. The structure of the device will be more stable and the durability will be better.

[0074] In other embodiments, the rigid shaft roller 202 on the columnar wind grille can be installed on the surface of the columnar wind grille via a height-adjustable support seat, or the rigid shaft roller 202 is fixed to the support seat 203 via a height adjustment mechanism, and the height of the rigid shaft roller 202 can be adjusted to adjust the diameter of the columnar inner molding surface 204.

[0075] Embodiment 3: On the basis of Embodiment 2, the outer forming air blowing mechanism 3 includes an arc changing mechanism, a blowing component and a roller group. The blowing component is provided with a plurality of blowing ports. The arc changing mechanism can change the roller group into an arc to form a cylindrical outer forming surface with a central angle greater than 180°, and is adapted to the curvature of the cylindrical inner forming surface 204 of the inner forming air blowing mechanism 2; at the same time, the plurality of blowing components are changed into an arc, and a cylindrical outer blowing surface is formed by the blowing ports on the plurality of blowing components. The arc changing mechanism is preferably an arc changing mechanism that can be pulled up to start an arc and is commonly used in the art, specifically a pullable chain plate type arc changing mechanism, and the blowing component is a wind grille. Figure 8 As shown, the externally formed air blowing mechanism 3 is arranged on the frame 1, the roller group includes a plurality of conveying rollers, the wind grid is located between two adjacent conveying rollers, the ends of the conveying rollers and the wind grid are connected to a pullable chain plate type arc changing mechanism, and the arc changing mechanism that can be pulled to start the arc includes two pulling ends. Specifically, the two lifting ends of the chain plate type arc-changing mechanism that can be lifted are respectively connected to a chain lifting assembly 4 on the frame 1, and the lifting end is pulled by the chain lifting assembly 4, and the chain plate type arc-changing mechanism that can be lifted is bent to drive the external molding blower mechanism 3 to bend and form. The chain lifting assembly 4 uses a different-side lifting method to lift the lifting end of the chain plate type arc-changing mechanism that can be lifted. Each lifting end is connected to a chain lifting assembly, and each chain lifting assembly and the corresponding connected lifting end are cross-arranged, that is, the chains used for lifting are cross-arranged to increase the bendable central angle of the external molding blower mechanism 3, forming a cylindrical external molding surface with a central angle greater than 180°, so as to facilitate the formation of an external molding surface that matches the shape of the target glass outer surface, so as to facilitate the molding of the columnar glass and the blowing and tempering of the outer surface. The chain lifting assembly includes a lifting chain and a sprocket. Optionally, the two chain lifting assemblies share a lifting motor or each uses a lifting motor.

[0076] In this embodiment, the outer forming air blowing mechanism 3 forms a columnar outer blowing surface while forming a columnar outer forming surface, which is used to blow and temper the outer surface of the columnar glass. In other embodiments, the blowing assembly and roller group of the outer forming air blowing mechanism can each be connected to an arc changing mechanism. During the forming and tempering process, the roller group can first be arced to form a columnar outer forming surface and participate in the forming, and then multiple blowing assemblies are arced to form a columnar outer blowing surface and blow air.

[0077] In other embodiments, further, the central angle of the columnar inner blowing surface of the inner molding air blowing mechanism 2 is greater than 180°, and the central angle of the columnar outer blowing surface of the outer molding air blowing mechanism 3 is greater than 180°. The columnar inner blowing surface of the inner molding air blowing mechanism 2 and the columnar outer blowing surface of the outer molding air blowing mechanism cooperate with each other, and when the inner and outer surfaces of the columnar glass with a central angle greater than 180° are blow-tempered, the tempering effect is better.

[0078] like Fig. 9 and Fig.10The inner forming air blowing mechanism 2 is arranged above the outer forming air blowing mechanism 3. When the glass reaches the predetermined position on the outer forming air blowing mechanism 3 and changes into an arc, the inner forming air blowing mechanism 2 cooperates to drive the glass to bend and form. Then, the outer forming air blowing mechanism 3 and the inner forming air blowing mechanism 2 are blown and tempered at the same time.

[0079] In other embodiments, in the externally formed air blowing mechanism 3, a lifting arc changing mechanism may be used to replace the lifting arc changing mechanism, which can also play the role of bending into an arc.

[0080] Example 4: Fig.11 As shown, the difference between this embodiment and embodiment 2 or 3 is that the structure of the columnar barrel structure of the inner forming air blowing mechanism 2 is different. In this embodiment, the columnar barrel structure of the inner forming air blowing mechanism 2 includes two or more barrel assemblies 206, and the roller assembly is arranged on the outer side of the barrel assembly 206. Specifically, a roller or a roller wheel is arranged on the side of the barrel assembly 206 facing the inner surface of the glass, and the roller assemblies on the outer sides of the two or more barrel assemblies 206 are further fitted into a columnar inner forming surface that matches the shape of the inner surface of the target columnar glass. The barrel assemblies are all hollow barrel structures, and the cold air channel is arranged inside the hollow barrel structure. Blowing holes are arranged on the barrel assemblies. The multiple blowing holes on the two or more barrel assemblies 206 form a columnar inner blowing surface that matches the shape of the inner surface of the target columnar glass. The columnar barrel structure can also realize the molding, tempering and separation of the columnar glass, and the selection is more flexible.

[0081] In other embodiments, the blowing outlet is a nozzle outlet arranged on the blowing hole; the columnar inner blowing surface is fitted by the outlets of multiple nozzles, and the height or length of the nozzle can be adjusted to fit the blowing surfaces of different shapes or radii, which is more flexible.

[0082] Example 5: In this example, the columnar wind grid of the internal molding air blowing mechanism 2 adopts the same columnar cylinder structure as that of Example 2, with the difference that the roller assembly on the circular surface of the columnar cylinder structure includes a plurality of flexible shaft rollers spaced apart along the main line direction of the columnar cylinder structure 201, the flexible shaft rollers are wound along the circumferential direction of the columnar cylinder structure, and rollers are installed on the flexible shaft rollers, so that the rolling direction of the rollers is parallel to the glass conveying direction.

[0083] Correspondingly, the blowing component of the outer molding air blowing mechanism 3 is a wind box, and the roller group includes a plurality of flexible shaft rollers.

[0084] The outer forming blower mechanism 3 and the inner forming blower mechanism 2 work together to realize the forming, tempering and stripping of small-opening columnar glass and the forming, tempering and stripping of large-opening columnar glass.

[0085] Preferably, the generatrix direction of the columnar inner molding surface of the inner molding air blowing mechanism 2 is parallel to the conveying direction of the glass entering the columnar glass molding and tempering integrated device, so that the production continuity is better, and the inner molding air blowing mechanism 2 is provided as one.

[0086] After forming and tempering, the inner forming blower mechanism 2 moves along one end of the generatrix direction of the columnar glass and separates from the columnar glass. Then the columnar glass is output along the input direction, and continuous production can also be achieved.

[0087] Embodiment 6: A columnar glass forming and tempering device comprises a heating furnace and a columnar glass forming and tempering integrated device in any of the above embodiments. After being heated by the heating furnace, the glass enters the forming and tempering integrated device for forming and tempering.

[0088] Furthermore, in other embodiments, there are multiple internal molding air blowing mechanisms, which respectively form columnar structures with different set curvatures and can be replaced according to the target glass radius. The external molding air blowing mechanism can cooperate with the columnar structures with different set curvatures to perform arc changes to different degrees, thereby realizing the molding and tempering of glass with different radii, which can reduce equipment investment and realize the molding and tempering of glass of more specifications.

[0089] Embodiment 7: A method for producing columnar tempered glass, using the above-mentioned integrated molding and tempering device, comprises the following steps:

[0090] S1: Heating step, the glass enters the heating furnace and is heated before being output to form hot glass;

[0091] S2: forming and tempering step, the hot glass is formed and tempered by the inner forming blower mechanism 2 and the outer forming blower mechanism 3;

[0092] S3: a sheet-detaching step, in which the inner molding blower mechanism 2 is moved out along one or both sides of the columnar glass generatrix direction under the drive of the moving mechanism to achieve separation from the columnar glass;

[0093] S4: unloading step, the columnar glass is transported to the next workstation along the transmission direction of the conveying roller.

[0094] The production method can smoothly realize the shaping and tempering of small-opening columnar tempered glass and smoothly realize the stripping of columnar tempered glass, thus solving the problem that small-opening columnar tempered glass cannot be stripped and removed.

[0095] In other embodiments, a pre-molding feeding step is included between S1 and S2, when the inner molding blower mechanism 2 is located at the upper part, the hot glass is transported to a predetermined position by rollers in the flattened outer molding blower mechanism 3, so that the glass feeding can be realized more smoothly.

[0096] In other embodiments, in step S2, the outer molding air blowing mechanism 3 changes its arc to drive the hot glass to bend and fit it onto the inner molding air blowing mechanism 2, completing the molding of the hot glass to form columnar glass; thereafter, the inner molding air blowing mechanism 2 and the outer molding air blowing mechanism 3 simultaneously blow air to cool the columnar glass, completing the tempering of the columnar glass, and making the molding smoother and more successful.

[0097] In other embodiments, during the air-blowing cooling process of step S2, air is introduced through the air inlet provided at the outer end of the inner forming air blowing mechanism 2 in the direction of the busbar, and then air is discharged through multiple air outlets on the columnar inner air blowing surface provided in the inner forming air blowing mechanism 2, so as to achieve air-blowing cooling of the inner surface of the columnar glass; at the same time, air is discharged through multiple air outlets on the columnar outer air blowing surface formed simultaneously after the outer forming air blowing mechanism 3 is curved, so as to achieve air-blowing cooling of the outer surface of the columnar glass, and jointly complete the air-blowing tempering of the formed glass. This air-blowing cooling method can make the air intake smoother, the glass receive the wind more evenly, and the separation from the columnar glass is also smoother, the structure of the inner forming air blowing mechanism 2 is more delicate and durable, the glass tempering effect is better, and the effect of hot glass tempering by wind is better.

Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
