Description

Technical Field

[0001] The utility model relates to the technical field of curved air grilles, in particular to a downward curved air grille used for bending and tempering glass. Background Art

[0002] Curved tempered glass not only offers the same safety and strength as tempered glass, but also features a beautiful, smooth curved surface that meets the higher aesthetic requirements of modern architecture. Therefore, curved tempered glass is widely used in glass curtain walls, skylights, observation elevators, interior decoration, and furniture.

[0003] Existing glass bending equipment uses a conveyor mechanism to transport glass between the top surfaces of two lower bending mechanisms. After the conveyor passes the top surface of the lower bending mechanism at the input end and delivers the entire piece of tempered glass to the forming area above the multiple wind grid bars between the two lower bending mechanisms, the two ends of the lower bending mechanisms are simultaneously lifted and bent, driving the two sides of the tempered glass to be bent upward to shape. After shaping is completed and the glass is cooled and tempered, the conveyor mechanism then outputs the bent tempered glass from the top surface of the lower bending mechanism at the output end to the unloading platform.

[0004] When the length of the tempered glass to be bent is large, the glass heated and softened by the heating furnace enters above multiple wind grid bars through the top surface of the lower bending arc mechanism at the input end. When the front end of the glass has not yet reached the top of the lower bending arc mechanism at the output end and the entire piece of glass has not been completely output from the heating furnace, the front end of the glass cannot be bent due to insufficient softening. At this time, a segmented bending and tempering process is required for bending and forming, that is, by gradually raising and bending the two ends of the lower bending arc mechanism at the output end, the glass is bent and formed in stages between the output end and the input end, and the lower bending arc mechanism at the input end is kept in a horizontal state during the gradual bending and forming. When the entire piece of glass completely enters above the multiple wind grid bars, the glass at the input end is bent and formed by lifting the two ends of the lower bending arc mechanism at the input end.

[0005] If the above-mentioned glass bending equipment is used to implement a segmented bending and tempering process for tempered glass, since the lower bending arc mechanism at the output end and the lower bending arc mechanism at the input end are not in the same plane during the segmented bending and forming, the existing transmission mechanism cannot meet the supporting requirements of the segmented bending and tempering process, affecting the normal operation of the tempering equipment.

[0060] Both ends of the linkage rod 84 are connected to one end of the two first cross universal couplings 386 , respectively. The other ends of the two first cross universal couplings 386 are connected to the other ends of the two first connecting shafts 387 , respectively.

[0061] like Figure 1 and Figure 2 The figure shows the installation structure of the lower and upper curvature grilles 2 for glass bending and tempering according to the present invention. The upper curvature grille 2 and the lower curvature grille are installed on the frame 1 in a vertically opposed manner.

[0062] like Figure 4 、 Figure 5 and Figure 7 As shown, multiple wind grid bars 42 extend along the X direction and are arranged in parallel, multiple support seats 32 are arranged at intervals along the X direction on the top surface of a wind grid bar 42 facing the glass, and the two ends of the wind grid bar 42 are spherically hinged with the two lower bending arc mechanisms 7 respectively, and the opposite surfaces of the two lower bending arc mechanisms 7 are installed with transmission gears 35; the soft shaft transmission roller 31 passes through the middle of the multiple support seats 32 in sequence along the Y direction and is mounted above the top surfaces of the multiple wind grid bars 42, and multiple air outlet boxes 41 are installed between the two soft shaft transmission rollers 31. The air outlet boxes 41 extend along the Y direction, and the multiple air outlet boxes 41 are arranged at intervals along the Y direction. The air outlet boxes 41 are connected to the wind grid bars 42 below and input cooling air. Cooling air can be blown to the bent glass through the air outlet boxes 41, so that the formed glass can be quenched and tempered; the top surfaces of the two lower bending arc mechanisms 7 are each mounted with a conveying roller for conveying glass, and the two transmission gears 35 are respectively connected to the corresponding conveying rollers through corresponding conveying components.

[0063] During the segmented bending process, the two ends of the linkage rod 84 are respectively connected through the transmission connection structure of the two first cross universal couplings 386 and the two first connecting shafts 387. Under the condition of keeping the lower bending arc mechanism 7 at the input end in a horizontal state, the motor reducer 381 can drive the first transmission component, the second transmission component and multiple soft shaft transmission rollers 31 to rotate synchronously through the linkage rod 384, and can make the glass enter the connected first transmission surface 301, the third transmission surface 303 and the second transmission surface 302 in turn, so that the glass can be continuously input to the top of multiple wind grid bars 42, and complete the segmented bending forming in the process of step-by-step rising. When the entire glass is completed, it can also be quenched and tempered by the cooling air output by the air outlet box 41, and then the tempered glass can be output from the second transmission surface 302 to the outside through the second transmission component.

[0064] Furthermore, it also includes a first lifting mechanism 5 and a second lifting mechanism 6;

[0065] The first lifting mechanism 5 and the second lifting mechanism 6 are respectively installed on the top of the frame 1; the output end of the first lifting mechanism 5 is connected to the two ends of the downward bending arc mechanism 7 at the input end through cables; the output end of the second lifting mechanism 6 is connected to the two ends of the downward bending arc mechanism 7 at the output end through cables.

[0066] like Figure 1 and Figure 2 As shown, the lifting and lowering of the two ends of the lower bending arc mechanism 7 at the input end and the two ends of the lower bending arc mechanism 7 at the output end are controlled by different lifting mechanisms respectively to meet the requirements of segmented bending forming.

[0067] Preferably, both ends of the air outlet box 41 are exposed on both sides of the wind grid bar 42 , and along the central axis of the wind grid bar 42 , a plurality of the air outlet boxes 41 are staggered and distributed.

[0068] like Figure 4 、 Figure 5 and Figure 11 As shown, the multiple air outlet boxes 41 are staggered relative to the central axis of the wind grid bar 42, so that the gaps between two adjacent and close air outlet boxes 41 are staggered, so that the end faces of the multiple air outlet boxes 41 exposed to the same wind grid bar 42 are not in the same plane parallel to the central axis of the wind grid bar 42, which can avoid the phenomenon that the corresponding parts of the glass are not blown by cooling air during the tempering process, thereby avoiding affecting the tempering quality of the glass.

[0069] In some embodiments, the transmission mechanism 3 further includes a support tube 34 and a transmission bearing 39;

[0070] The support tube 34 extends along the X direction, and the support tube 34 is located on the Y-outside of the plurality of wind grid bars 42;

[0071] The motor reducer 381 and the linkage rod 384 are respectively installed on the support tube 34; the transmission bearing 39 is mounted on the top surface of the support tube 34, and one end of the flexible shaft transmission roller 31 passes through the inner ring of the transmission bearing 39 and is then connected to the transmission wheel 385.

[0072] like Figure 4 As shown, the motor reducer 381 and the linkage rod 384 are installed on the Y-direction side of the support tube 34, and the flexible shaft transmission roller 31 with the transmission bearing 39 is driven to rotate through the transmission wheel 385, which can improve the operating stability and service life of the flexible shaft transmission roller 31.

[0073] Furthermore, the coupling assembly 382 includes a coupling gear 3821 and a driven gear 3822;

[0074] The driven wheel 3822 is sleeved on the middle part of the linkage rod 384 ; the coupling gear 3821 is sleeved on the outer peripheral surface of the output end of the motor reducer 381 , and the outer peripheral surface of the coupling gear 3821 is meshed with the outer peripheral surface of the driven wheel 3822 .

[0075] like Figure 5 As shown, the motor reducer 381 drives the linkage rod 384, multiple linkage wheels 383 and multiple transmission wheels 385 to rotate synchronously through the cooperation of the coupling gear 3821 and the driven wheel 3822.

[0076] Furthermore, the transmission mechanism 3 further includes a support seat 32, and the support seat 32 includes a connecting seat 322, a joint bearing 323 and two lateral hinge seats 321;

[0077] The flexible shaft transmission roller 31 includes a flexible shaft 311 and a conveying wheel 312;

[0078] The plurality of flexible shafts 311 extend along the Y direction and are arranged in parallel. The outer circumference of the flexible shaft 311 is provided with a plurality of conveying wheels 312 .

[0079] A rotation cavity 3221 is provided in the middle of the connecting seat 322; both ends of the connecting seat 322 extend in directions perpendicular to the axis of the rotation cavity 3221; a rotation cavity 3210 is provided at the top of the lateral hinge seat 321; both ends of the connecting seat 322 are rotatably inserted into the two rotation cavities 3210; the joint bearing 323 is rotatably mounted in the rotation cavity 3221; the bottom of the lateral hinge seat 321 is fixed to the top surface of the corresponding wind grid bar 42;

[0080] Multiple flexible shafts 311 extend along the X direction respectively, and each flexible shaft 311 passes through multiple joint bearings 323 located above different wind grid bars 42 in sequence; the outer circumference of the flexible shaft 311 is covered with multiple conveying wheels 312; at least one conveying wheel 312 is distributed between two adjacent rotating chambers 3221;

[0081] The Z-direction wheel surfaces of the plurality of conveying wheels 312 form the third conveying surface 302 for supporting and conveying the glass to be tempered.

[0082] Figure 4-10 As shown, the flexible shaft 311 can rotate in the plurality of support seats 32 through the joint bearings 323, so that the flexible shaft 311 will not get stuck and fail to rotate during the bending process.

[0083] At least one conveying wheel 312 is arranged between two adjacent support seats 32. The Z-direction wheel surfaces of the multiple conveying wheels 312 located on the multiple flexible shafts 311 form the third conveying surface 302 for supporting and conveying the glass to be tempered, so that the multiple flexible shafts 311 can drive the multiple conveying wheels 312 to rotate synchronously and convey the glass to be tempered along the running direction.

[0084] In some other embodiments, the transmission mechanism 3 further includes two support tubes 34, a plurality of transmission bearings 39, a plurality of second connecting shafts 36 and a plurality of second cross universal couplings 33;

[0085] The support tube 34 extends along the Y direction, and the two support tubes 34 are respectively arranged from the outside close to the two wind grid bars 42 located at the edge;

[0086] The plurality of transmission bearings 39 are divided into two groups, and the plurality of transmission bearings 39 in the same group are arranged at intervals along the Y direction on the top surface of the support tube 34;

[0087] One end of the second connecting shaft 36 is fitted with the transmission wheel 85 , and the other end of the second connecting shaft 36 passes through the transmission bearing 39 and is connected to one end of the second cross universal joint 33 , and the other ends of the two second cross universal joints 33 are respectively connected to the two ends of the flexible shaft 311 .

[0088] like Figure 7 and Figure 8As shown, when the curvature of the glass to be prepared is greater than the bendability of the soft shaft 311, the lower bending arc mechanism 7 drives the multiple wind grid bars 42 to bend and continuously increases the curvature to achieve the curvature required by the process; since the bendability of the soft shaft 311 is limited, if the second cross universal joint 33 is not used, and an installation structure in which the two ends of the soft shaft 311 are rigidly connected to the other ends of the two second connecting shafts 36 is adopted, or an installation structure in which the two ends of the soft shaft 311 are respectively inserted into the two transmission wheels 85, the soft shaft 311 will not be able to bend due to insufficient bendability, and the soft shaft 311 will hold back the multiple wind grid bars 42 and cannot continue to bend, causing the lower bending arc mechanism 7 to drive the multiple wind grid bars 42 to become stuck in the process of continuously increasing the curvature, thereby hindering the operation of the bending arc mechanism 7 to drive the multiple wind grid bars 42 to bend.

[0089] Therefore, the two ends of the flexible shaft 311 are respectively connected to the two second connecting shafts 36 inserted into the two transmission wheels 85 through the two second cross universal joints 33, so that the operation of the lower bending arc mechanism 7 to drive the multiple wind grid bars 42 to bend is not limited by the bendability of the flexible shaft 311, and the phenomenon of the lower bending arc mechanism 7 being stuck can be avoided.

[0090] Furthermore, the transmission mechanism 3 further includes a connecting plate 37;

[0091] One end of the support tube 34 is connected to one end of the adjacent wind grid bar 42 through the connecting plate 37 .

[0092] like Figure 7 and Figure 8 As shown, one end of the support tube 34 and one end of the adjacent wind grid bar 42 are connected together by a connecting plate 37 , so that the support tube 34 can bend and move along with the adjacent wind grid bar 42 .

[0093] Preferably, the outer peripheral surface of the conveying wheel 312 is wrapped with aramid heat insulation cotton.

[0094] The conveying wheel 312 is made of metal, and the outer surface of the conveying wheel 312 is wrapped with aramid heat-insulating cotton to prevent the tempered glass from sticking or cracking due to a large temperature difference when it contacts the conveying wheel 312 .

[0095] Furthermore, a plurality of the air outlet boxes 41 are installed between two adjacent flexible shafts 311;

[0096] The air outlet boxes 41 extend along the Y-axis direction, and a plurality of the air outlet boxes 41 located between two adjacent flexible shafts 311 are arranged at intervals along the X-direction.

[0097] like Figure 4-6 As shown, cooling air can be blown to the tempered glass after bending through the air outlet box 41, so that the tempered glass can be quenched and tempered.

[0098] Furthermore, the support seat 32 further includes two shaft sleeves 324;

[0099] Two ends of the connecting seat 322 are respectively fitted with two shaft sleeves 324;

[0100] The two ends of the connecting seat 322 are rotatably embedded in the two rotating chambers 3210 through the corresponding shaft sleeves 324;

[0101] The shaft sleeve 324 is provided with a limiting ring 3241;

[0102] The limiting ring 3241 surrounds the circumferential edge of the shaft sleeve 324 on a side close to the rotating cavity 3221 , and the limiting ring 3241 is used to abut against the edge of the corresponding rotating cavity 3210 .

[0103] like Figure 9 and Figure 10 As shown, the shaft sleeve 324 can reduce the rigid contact and friction between the two ends of the connecting seat 322 and the rotating cavity 3210, and improve the rotation flexibility and service life of the two ends of the connecting seat 322.

[0104] like Figure 10 As shown, the limiting ring 3241 can improve the installation stability of the sleeve 324 and prevent the sleeve 324 from passing through the rotating cavity 3210 and getting loose during operation.

[0105] Furthermore, the connecting seat 322 includes two halves that are mirror-symmetrical in upper and lower directions, and the rotating cavity 3221 is formed by closing two semicircular grooves that are symmetrically distributed in upper and lower directions.

[0106] like Figure 9 and Figure 10 As shown, the connecting seat 322 is divided into two halves that are mirror-symmetrical, which is more conducive to processing and forming, and can also improve the installation convenience of the joint bearing 323.

[0107] Preferably, the shaft sleeve 324 is made of polytetrafluoroethylene.

[0108] The shaft sleeve 324 made of polytetrafluoroethylene has better wear resistance and service life.

[0109] In summary, if Figure 1-11In the embodiment of the utility model shown, the lower bending wind grid used for bending and tempering glass, the two ends of the linkage rod 84 are respectively connected by two first cross universal couplings 386 and two first connecting shafts 387 through a transmission connection structure, which can allow the glass to enter the connected first conveying surface 301, the third conveying surface 303 and the second conveying surface 302 in sequence, so that the glass can be bent and formed in sections during the process of gradual elevation. When the entire glass is bent and formed, it can also be quenched and tempered by the cooling air output by the air outlet box 41, and then the tempered glass can be output outward from the second conveying surface 302 through the second conveying assembly, so that the conveying mechanism 3 including the first conveying assembly, the second conveying assembly and the first cross universal coupling 386 can meet the supporting requirements of the segmented bending and tempering process.
