DETAILED DESCRIPTION

[0058] 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.

[0059] Example 1: Figure 1 and Figure 2As shown, a columnar glass tempering device includes an inner blowing mechanism 2 for blowing air to the inner surface of the columnar glass and an outer blowing mechanism 3 for blowing air to the outer surface of the columnar glass; the inner blowing mechanism 2 includes a columnar wind grid 201, an air inlet of the columnar wind grid 201 is arranged at the outer end of its busbar direction, a plurality of cold air channels are arranged inside the columnar wind grid along the busbar direction, a plurality of blowing ports connected to the cold air channels are arranged on the columnar wind grid, and the plurality of blowing ports constitute a columnar blowing surface.

[0060] In this embodiment, the inner air blowing mechanism 2 and the outer air blowing mechanism 3 are also respectively connected to fans for providing cooling air.

[0061] The tempering device of the utility model can realize the blowing tempering of the inner and outer surfaces of the columnar glass with a small opening whose central angle is greater than 180°, and can also realize the blowing tempering of the columnar glass with a large opening whose central angle is less than or equal to 180°; in addition, through the design optimization of the air inlet, the cold air channel and the columnar blowing surface of the inner blowing mechanism, the cooling air inlet and outlet can be made smoother, the blowing on the inner surface of the columnar glass can be more uniform and more stable, the glass tempering effect is better, and the equipment durability is better.

[0062] 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.15 , Fig.16 As shown, the central angles are respectively less than 180° and greater than 180°.

[0063] Embodiment 2: Based on Embodiment 1, Figure 3 As shown, a columnar glass tempering device, an external air blowing mechanism 3 is arranged on a frame 1 of the tempering equipment, and the external air blowing mechanism 3 is located below the internal air blowing mechanism 2.

[0064] The columnar wind grille 201 is a columnar barrel structure. Preferably, the columnar barrel structure is a cylindrical barrel. In other embodiments, columnar barrel structures of other shapes 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 an elliptical barrel, or a semi-elliptical barrel with a central angle of α, 180°<α<360°. In the specific selection of α, it is sufficient that α is greater than the central angle of the target glass cylinder. The above-mentioned columnar wind grille structures are more feasible and can be selected according to the shape of the target glass and the actual situation, and are more convenient to set up. Preferably, the columnar barrel structure is an integrated structure, and a cold air channel is arranged inside the columnar wind grille along the busbar direction, so that the structure is more practical, durable and stable.

[0065] The blowing port is a blowing hole directly opened on the surface of the cylindrical tube. In other embodiments, the blowing port is an outlet of a nozzle arranged on the blowing hole; the columnar blowing surface is formed by fitting the outlets of multiple nozzles, and the height or length of the nozzle can be adjusted to fit blowing surfaces of different shapes or radii, which is more flexible.

[0066] Further, the outer blowing mechanism 3 includes an arc changing mechanism and a plurality of blowing components, and a plurality of blowing ports are arranged on the blowing components. The arc changing mechanism can change the plurality of blowing components into an arc, and form a columnar blowing surface composed of the blowing ports of the plurality of blowing components, and is adapted to the curvature of the columnar blowing surface of the inner blowing mechanism; the arc changing mechanism of the outer blowing mechanism 3 is an arc changing mechanism that can be pulled up to start an arc, specifically a chain plate type arc changing mechanism that can be pulled up and started commonly used in the art, and the arc changing mechanism that can be pulled up and started to start an arc includes two pulling ends. Specifically, the two pulling ends of the pullable chain plate type arc changing mechanism are respectively connected to a chain pulling component 4 on the frame 1, and the chain pulling component 4 pulls the pulling end, and the outer blowing mechanism 3 is driven to bend and change the arc by bending the pullable chain plate type arc changing mechanism, and each pulling end is connected to a chain pulling component, so as to form an outer blowing surface adapted to the shape of the outer surface of the target glass, so as to facilitate the blowing and tempering of the columnar glass. The chain lifting assembly includes a lifting chain and a sprocket. Optionally, two chain lifting assemblies share a lifting motor or each uses a lifting motor.

[0067] In other embodiments, further, the central angle of the columnar blowing surface of the inner blowing mechanism is greater than 180°, and the chain lifting assembly 4 of the outer blowing mechanism adopts a different-side lifting method for lifting the lifting end of the liftable chain plate type arc-changing mechanism. Specifically, 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 outer blowing mechanism 3, thereby forming a columnar blowing surface with a central angle greater than 180°. The columnar blowing surface of the inner blowing mechanism and the columnar blowing surface of the outer blowing mechanism cooperate with each other, and the effect is better when blowing and tempering columnar glass with a central angle greater than 180°.

[0068] In this embodiment, the external blowing mechanism 3 can directly cooperate with the columnar wind grid 201 to blow and temper the columnar glass. It can well achieve blow and temper the columnar glass with a central angle greater than 180°, and can also achieve blow and temper the columnar glass with a central angle less than 180°. The structure is simple.

[0069] In other embodiments, the external blowing mechanism 3 may also adopt a jacking-up arcing method instead of the pulling-up arcing method of the chain pulling assembly 4, which can also play the role of bending into an arc.

[0070] Embodiment 3: Based on embodiment 2, Figure 4As shown, the internal air blowing mechanism 2 also includes a rolling assembly arranged on the cylindrical barrel, and the rolling assembly includes a plurality of rollers arranged at intervals along the circumferential direction of the cylindrical barrel, and the rollers are preferably hard shaft rollers 202, and the length direction of the rollers is arranged parallel to the generatrix direction of the columnar air blowing surface. The rolling assembly is fitted into a rolling cylinder 204 concentric with the columnar air blowing surface, driving the glass to rotate and swing around the rolling cylinder 204 to be exposed to the wind, and the glass tempering effect is better. In addition, the rolling assembly can also play a molding role.

[0071] In other embodiments, Figure 5 As shown, the rolling assembly can also be arranged on an elliptical cylinder.

[0072] In this embodiment, the outer blower mechanism 3 also includes a conveying roller, and the conveying roller also uses a hard shaft roller. At this time, the state of the outer blower mechanism 3 in conjunction with the inner blower mechanism 2 when tempering is as follows Figure 6 shown.

[0073] In other embodiments, a soft-shaft roller can be used to replace the hard-shaft roller 202 of the internal air blowing mechanism 2, and the same arrangement is adopted. Alternatively, the hard-shaft roller of the internal air blowing mechanism 2 can be replaced by a roller, and the generatrix direction of the roller is parallel to the generatrix direction of the columnar blowing surface.

[0074] In other embodiments, the rigid shaft roller 202 on the columnar wind grid 201 can be installed on the columnar wind grid 201 via a height-adjustable support seat, or the rigid shaft roller is fixed to the support seat via a height adjustment mechanism, and the support seat 203 is arranged on the columnar wind grid 201. Adjusting the height of the rigid shaft roller can adjust the blowing distance between the columnar blowing surface of the internal blowing mechanism and the columnar glass.

[0075] Furthermore, at this time, the conveying direction of the glass into the tempering device is perpendicular to the generatrix direction of the columnar blowing surface, so that the glass feeding can be better realized with higher efficiency.

[0076] Embodiment 4: The difference between this embodiment and embodiment 3 is that the structure of the internal air blowing mechanism 2 is different, such as Figure 7 shown.

[0077] In this embodiment, the columnar wind grid 201 of the internal blowing mechanism 2 includes two or more internal blowing units 206. The internal blowing unit 206 is a cylindrical structure. A cold air channel is arranged inside the internal blowing unit 206 along the busbar direction. A plurality of blowing ports are arranged on the internal blowing unit 206. The blowing ports of the plurality of internal blowing units form a columnar blowing surface. The rolling component is arranged on the side of the internal blowing unit 206 facing the inner surface of the glass. The flexibility of this structure is better.

[0078] In other embodiments, the columnar barrel structure in Example 2 may also be divided into a plurality of internal blowing units, and the plurality of internal blowing units together constitute the columnar barrel structure, which is also feasible.

[0079] Embodiment 5: Based on any of the above embodiments, Figures 8 to 10 As shown, in this embodiment, two inner air blowing mechanisms 2 are provided, and the columnar air grilles 201 of the two inner air blowing mechanisms 2 are coaxially arranged.

[0080] In order to facilitate the smooth removal of the columnar glass with small opening after tempering, two internal blower mechanisms 2 are respectively arranged on the left movable slide 5 and the right movable slide 7 on the left and right sides of the frame 1. The left movable slide 5 is slidably arranged on the left ground rail 6, and the right movable slide 7 is slidably arranged on the right ground rail 8. Fig. 9 , 10 As shown, taking the inner blowing mechanism on the left side as an example, during the glass tempering process, the left movable slide is located at the right end of the left ground rail, and similarly, the right movable slide is located at the left end of the right ground rail, and the two ends of the inner blowing mechanism are butted; after the glass is formed, it will be wound around the inner blowing mechanism, especially for columnar glass with a central angle greater than 180°. The opening on the glass column is smaller than the diameter of the inner blowing mechanism, so it is difficult to separate the glass from the inner blowing mechanism. At this time, the left and right movable slides can be slid to move the inner blowing mechanism out from the end of the tempered columnar glass along its busbar direction to achieve separation from the columnar glass.

[0081] In this embodiment, preferably, two inner air blowing mechanisms 2 are distributed and connected with a fan, the air outlet of the fan is connected to the air inlet of the columnar wind grid, the left fan 6 is arranged on the left movable slide 5, and the right fan 9 is arranged on the right movable slide 7, for supplying air to the inner air blowing mechanisms respectively. This arrangement greatly facilitates the placement of the fan and the convenience of air supply. In other embodiments, the fan can also be arranged in other positions, such as on a rack, in which case the fan and the inner air blowing mechanism can be connected by a soft air duct.

[0082] The following is the columnar glass tempering process corresponding to the tempering device described in this embodiment: after the air blowing tempering is completed, the chain lifting assembly 4 drives the outer air blowing mechanism 3 below to flatten, and controls the two movable slides to move the two inner air blowing mechanisms outward and pull them out from the end of the tempered columnar glass. Finally, the conveying roller of the outer air blowing mechanism 3 runs to deliver the tempered columnar glass.

[0083] Furthermore, after the external air blowing structure 3 changes its arc, the columnar glass is driven by the rolling assembly to rotate and swing around the columnar air grille in one direction or two directions, which can further improve the tempering quality of the glass.

[0084] In the present embodiment, two coaxially arranged internal air blowing mechanisms 2 are used. In other embodiments, only one internal air blowing mechanism 2 may be used. In this case, one end of the internal air blowing mechanism 2 is connected to the corresponding movable slide, and the whole is in a suspended state. If the size of the internal air blowing mechanism along the busbar direction of the columnar glass is set too large, the internal air blowing mechanism will sag and deform due to its center of gravity offset and the weight of the glass under long-term use, and the end is prone to sag. Therefore, it is more suitable for tempering smaller glass. When the size of the glass along the busbar direction of the columnar glass is large, it is necessary to adopt two internal air blowing mechanisms 2, and the structure of the device will be more stable and durable.

[0085] Embodiment 6: Based on Embodiment 4, the columnar air grille is connected to a lifting mechanism, wherein the two or more inner blowing units are connected in an openable and closable manner, and the relative movement between the inner blowing units 206 includes a rotatable opening and closing connection or a slidable opening and closing connection; or each inner blowing unit is connected to a lifting mechanism. The specific structural designs are as follows.

[0086] (1) Rotatable opening and closing connection: Fig.11 As shown, the columnar air grille includes two inner blowing units 206, which are connected by rotation. Each inner blowing unit is driven by a driving mechanism to realize rotation and opening and closing. The inner blowing unit 206 is a cylindrical tube with an arched cross section, and the lower ends of the two inner blowing units 206 are hinged. The driving mechanism is such as an electric push rod, a cylinder, an oil cylinder, etc., taking an electric push rod as an example.

[0087] The method of separating the glass from the inner blowing mechanism after tempering: after controlling the opening and closing of the two inner blowing units 206 to achieve the target shape, cooperate with the outer blowing mechanism to temper the glass by the wind, and then flatten the outer blowing mechanism 3 to support the glass, and then control the two inner blowing units 206 to rotate and close, so that the width of the inner blowing mechanism 2 is smaller than the width of the cylindrical opening of the tempered columnar glass, and then the lifting mechanism drives the inner blowing mechanism 2 to move out of the opening of the glass, and then the roller of the outer blowing mechanism 3 sends the glass out.

[0088] (2) Sliding opening and closing connection: Fig.12 As shown, the columnar wind grille includes three inner blowing units 206, and the inner blowing unit 206 is a hollow cylindrical tube with an arched cross-section, wherein two of the inner blowing units 206 can be relatively slidably opened and closed. By sliding the two slidable inner blowing units 206 toward each other, the width of the entire inner blowing mechanism 2 is reduced to be smaller than the width of the cylindrical opening of the tempered columnar glass, so that the inner blowing mechanism 2 can be easily moved out of the tempered columnar glass by lifting.

[0089] The method of separating the tempered glass from the inner blowing mechanism: After the glass is tempered, the outer blowing mechanism 3 is flattened to support the glass, the movable inner blowing unit 206 is controlled to slide, and then the columnar wind grid is raised by a lifting mechanism such as a cylinder, so that the inner blowing mechanism 2 is separated from the glass from the cylindrical opening of the glass, and finally the glass is sent out by the roller of the outer blowing mechanism 3.

[0090] (3) The ways in which they can be raised and lowered: Fig.13 As shown, the columnar air grille includes two or three inner blowing units 206, which together form a combined columnar cylinder structure with a central angle greater than 180°. The inner blowing unit 206 is a hollow cylindrical cylinder with a fan-shaped cross section, each inner blowing unit is connected to a lifting mechanism, and each inner blowing unit 206 can be detached from the glass from the cylindrical opening of the tempered glass, thereby detaching the inner blowing mechanism 2 from the glass.

[0091] The method of separating the glass tempering and the internal blowing mechanism: After the glass is tempered, the external blowing mechanism 3 is flattened to support the glass, and multiple internal blowing units 206 are controlled to rise upward toward the cylindrical opening of the columnar glass, and separate from the glass respectively, and finally the glass is sent out by the roller of the external blowing mechanism 3.

[0092] In the present embodiment, the columnar wind grid of the inner blowing mechanism is composed of two or more inner blowing units, which not only facilitates the demolding of the glass after tempering, but also allows the inner blowing surface of the inner blowing mechanism to form other shapes according to the shape of the inner blowing units, such as elliptical, U-shaped, etc. inner blowing surfaces.

[0093] Example 7: Based on Example 2, the difference is that the rolling assembly includes a plurality of flexible shaft rollers spaced apart along the busbar direction of the columnar wind grid 201, and the flexible shaft rollers are wound along the circumferential direction of the columnar wind grid 201. This structure can also realize mobile wind reception of the glass.

[0094] In other embodiments, further, the conveying direction of the glass into the tempering device is parallel to the generatrix direction of the columnar blowing surface, and the feeding efficiency is higher.

[0095] As another implementation manner, in this embodiment, a suction cup may also be used to load and unload the glass.

[0096] Embodiment 8: The inner air blowing mechanism in the above embodiment is preferably located above the outer air blowing mechanism. In this embodiment, the inner air blowing mechanism 2 may also be arranged below the outer air blowing mechanism 3. Fig.14 As shown, the tempering of columnar glass can also be achieved.

[0097] Optionally, a suction cup mechanism may be used to advance the glass.

[0098] Embodiment 9: A columnar glass tempering device, comprising a heating device and a tempering device arranged in sequence, wherein the tempering device is the columnar glass tempering device described in any of the above embodiments.

[0099] Furthermore, in other embodiments, there are multiple inner air blowing mechanisms, each of which has a columnar structure with a different set curvature, and can be replaced according to the target glass radius. The outer air blowing mechanism can cooperate with the columnar structure with a different set curvature to perform arc changes to different degrees to achieve the tempering of glass with different radii, which can reduce equipment investment and achieve the tempering of glass of more specifications.

[0100] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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.
