Description

Technical Field

[0001] The utility model relates to the technical field of wind grid bar transmission, in particular to a wind grid bar transmission structure that is adaptable to step-by-step bending and tempering. 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] The glass bending equipment in the existing technology uses a conveying mechanism to transport glass. The conveying mechanism includes a linkage rod, on which a plurality of linkage wheels are mounted. The plurality of linkage wheels drive a plurality of flexible shafts mounted above a plurality of wind grid bars to rotate synchronously through belts. The two ends of the linkage rod are connected to the end faces of two transmission gears mounted on the opposite surfaces of the two lower bending arc mechanisms. The top surfaces of the two lower bending arc mechanisms are both equipped with conveying rollers for conveying glass. The two transmission gears are respectively connected to the corresponding conveying rollers through corresponding transmission components. Based on the above settings, only one set of conveying mechanism is needed to complete the conveying of glass between the top surfaces of the two lower bending arc mechanisms and the two lower bending arc mechanisms.

[0004] When the length of the tempered glass to be bent is large, the glass heated and softened by the heating furnace passes through the top of the lower bending arc mechanism at the input end and enters the top of multiple wind grid bars. 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 step-by-step bending and tempering process is required to bend and shape the glass, that is, through the step-by-step bending and raising of the lower bending arc mechanism at the output end, the glass is bent and formed in steps 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 step-by-step bending and forming. When the entire piece of glass is completely output from the heating furnace, the entire piece of glass is bent and formed by bending through the lower bending arc mechanism at the input end.

[0005] Since the connection between the two ends of the linkage rod and the end faces of the two transmission gears is a rigid connection, during the step-by-step bending process, the lower bending arc mechanism at the input end is in a horizontal state, while the lower bending arc mechanism at the output end is in a lifted and bent state, causing the connection end between the linkage rod and the transmission gear at the input end to generate a torque on the connection surface of the transmission gear. This torque is a torque that squeezes the upper end face of the transmission gear and stretches the lower end face of the transmission gear, thereby causing the lower bending arc mechanism at the input end to deform, affecting the normal operation of the tempering equipment.

[0047] A wind grid bar transmission structure suitable for step-by-step bending and tempering, comprising a plurality of flexible shaft transmission rollers 1 and a driving device 8, a plurality of wind grid bars 3 extending along the X direction and arranged in parallel, a plurality of support seats 2 arranged at intervals along the X direction on the top surface of a wind grid bar 3 facing the glass, the two ends of the wind grid bar 3 are respectively spherically hinged with two lower bending arc mechanisms 7, the bottoms of the two lower bending arc mechanisms 7 are respectively equipped with two transmission gears 5, and the two transmission gears 5 are arranged opposite to each other; the flexible shaft transmission roller 1 passes through the middle parts of the plurality of support seats 2 located on the top surfaces of different wind grid bars 3 in sequence along the Y-axis direction, so that the flexible shaft transmission roller 1 is mounted on the top surfaces of the plurality of wind grid bars 3; the driving device 8 comprises a motor reducer 81, a coupling assembly 82, a linkage rod 84, a plurality of transmission belts, a plurality of linkage wheels 83 and a plurality of transmission wheels 85, the driving device 8 also comprises two first cross universal couplings 86 and two first connecting shafts 87, one end of the two first connecting shafts 87 are respectively inserted into the two transmission gears 5, and the other ends of the two first connecting shafts 87 extend relative to each other;

[0048] The motor reducer 81 and the linkage rod 84 are respectively installed on the wind grid bar 3 located on the outside; the transmission wheel 85 is mounted on one end of the flexible shaft transmission roller 1; the motor reducer 81 is connected to the outer peripheral surface of the linkage rod 84 through the coupling assembly 82, and a plurality of linkage wheels 83 are mounted on the outer peripheral surface of the linkage rod 84. The linkage wheels 83 correspond to the transmission wheels 85 one by one and are connected through the transmission belt.

[0049] Both ends of the linkage rod 84 are connected to one end of the two first cross universal couplings 86 , respectively. The other ends of the two first cross universal couplings 86 are connected to the other ends of the two first connecting shafts 87 , respectively.

[0050] like Figure 1-3 The wind grid bar transmission structure adapted to step-by-step bending and tempering of the utility model shown in the figure has a plurality of blowing boxes 6 installed between the two soft shaft drive rollers 1, and the blowing boxes 6 extend along the Y-axis direction. The blowing boxes 6 between the two soft shaft drive rollers 1 are arranged at intervals along the Y-axis direction, and the blowing boxes 6 are connected to the wind grid bar 3 below and input cooling air. The cooling air can be blown to the bent glass through the blowing boxes 6, so that the formed glass can be quenched and tempered; the top surfaces of the two lower bending arc mechanisms 7 are both equipped with conveying rollers for conveying glass, and the two transmission gears 5 are respectively connected to the corresponding conveying rollers through corresponding transmission components.

[0051] When the length of the tempered glass to be bent is large, it is impossible to complete the shaping of the entire piece of glass by bending the bending mechanisms 7 at both ends at one time. A step-by-step bending and tempering process must be used to bend the glass in steps. The operation process is as follows: the glass heated and softened by the heating furnace is transported by the conveying roller above the lower bending mechanism 7 (defined as the input end lower bending mechanism 7) located at the input end into the top of multiple wind grid bars 3. The lower bending mechanism 7 (defined as the output end lower bending mechanism 7) connected to the output end of the wind grid bar 3 (i.e., the end away from the glass heating furnace) is first lifted and bent into an arc, driving the end of the two linkage rods 84 close to the output end of the wind grid bar 3 to rise, so that the forward section of the glass forms a curved surface. During the period when the glass is not completely output from the heating furnace, the middle part of the glass continuously passes through the top of the input end lower bending mechanism 7 in a horizontal state and enters multiple wind grid bars. Above the strip 3, the input end lower bending mechanism 7 needs to maintain a horizontal state until the entire piece of glass is completely output from the heating furnace; during the output process of the glass, the output end lower bending mechanism 7 can be raised in batches according to the length of the glass. While the output end of the glass is bent and formed, the corresponding part of the middle of the glass is raised and bent in batches following the output end of the glass during the forward process to form an arc surface. When the entire piece of glass is completely output from the heating furnace, the input end lower bending mechanism 7 is raised to the set position and then bent into the target curvature, and the input end and output end of the glass are respectively pressed against the corresponding upper bending mechanism to form, so that the entire piece of glass forms the set curved surface and is formed, and then cooling air is output through the blow box 6 to quench and temper the formed glass, and then the glass is output through the conveying roller located above the output end lower bending mechanism 7, that is, a step-by-step bending and tempering operation cycle is completed.

[0052] The two ends of the linkage rod 84 are respectively connected by two first cross universal couplings 86 and two first connecting shafts 87. During the output process of the glass, as well as when the output end of the glass is bent and formed and the middle part of the glass is synchronously bent and formed in stages, the lower bending arc mechanism 7 at the input end can be kept in a horizontal state, so that the glass can smoothly pass over the top of the lower bending arc mechanism 7 at the input end and enter over the top of multiple wind grid bars 3, thereby allowing the glass to successfully complete the step-by-step forming, and in the process of step-by-step forming, the lower bending arc mechanism 7 at the input end can be prevented from twisting and deformation.

[0053] In addition, the wind grid bar transmission structure adapted to step-by-step bending and tempering of the utility model can also be used for quenching and tempering of flat glass. As long as the two lower bending arc mechanisms 7 at the input and output ends are kept in a horizontal state, it can operate normally and has better versatility.

[0054] In some embodiments, two support tubes 4 and a plurality of transmission bearings 9 are further included;

[0055] The support tube 4 extends along the X direction, and the two support tubes 4 are respectively close to the two outermost wind grid bars 3 from both sides along the Y direction;

[0056] The motor reducer 81 and the linkage rod 84 are respectively installed on the outer side surfaces of the corresponding support tube 4; the transmission bearing 9 is mounted on the top surface of the support tube 4, and one end of the soft shaft transmission roller 1 passes through the inner ring of the transmission bearing 9 and is then connected to the transmission wheel 85.

[0057] like Figure 1 As shown, the motor reducer 81 and the linkage rod 84 are installed on the Y-direction side of the support tube 4, and the flexible shaft transmission roller 1 with the transmission bearing 9 is driven to rotate through the transmission wheel 85, which can improve the operating stability and service life of the flexible shaft transmission roller 1.

[0058] Furthermore, the coupling assembly 82 includes a coupling gear 821 and a driven gear 822;

[0059] The driven wheel 822 is sleeved on the middle part of the linkage rod 84 ; the coupling gear 821 is sleeved on the outer peripheral surface of the output end of the motor reducer 81 , and the outer peripheral surface of the coupling gear 821 is meshed with the outer peripheral surface of the driven wheel 822 .

[0060] like Figure 2 As shown, the motor reducer 81 drives the transmission rod 84, multiple linkage wheels 83 and multiple transmission wheels 85 to rotate synchronously through the transmission cooperation of the coupling gear 821 and the driven wheel 822.

[0061] Furthermore, the support seat 2 includes a connecting seat 22, a joint bearing 23 and two lateral hinge seats 21;

[0062] The flexible shaft transmission roller 1 includes a flexible shaft 11 and a plurality of conveying wheels 12;

[0063] A rotation cavity 221 is provided in the middle of the connecting seat 22; both ends of the connecting seat 22 extend in directions perpendicular to the axis of the rotation cavity 221; a rotation cavity 210 is provided at the top of the lateral hinge seat 21; both ends of the connecting seat 22 are rotatably inserted into the two rotation cavities 210; the joint bearing 23 is rotatably mounted in the rotation cavity 221; the bottom of the lateral hinge seat 21 is fixed to the top surface of the corresponding wind grid bar 3;

[0064] Multiple flexible shafts 11 extend along the X direction respectively, and each flexible shaft 11 passes through multiple joint bearings 23 located above different wind grid bars 3 in sequence; the outer peripheral surface of the flexible shaft 11 is covered with multiple conveying wheels 12; at least one conveying wheel 12 is distributed between two adjacent rotating chambers 221.

[0065] Figure 4-6 As shown, the flexible shaft 11 can rotate in the plurality of support seats 2 through the joint bearing 23, so that the flexible shaft 11 will not get stuck and fail to rotate during the bending process.

[0066] At least one conveying wheel 12 is arranged between two adjacent support seats 2. The Z-direction wheel surfaces of the multiple conveying wheels 12 located on the multiple flexible shafts 11 form a curved arc surface for supporting and conveying the glass to be tempered, so that the multiple flexible shafts 11 can drive the multiple conveying wheels 12 to rotate synchronously and convey the glass to be tempered along the running direction.

[0067] In some other embodiments, two support tubes 4, a plurality of transmission bearings 9, a plurality of second connecting shafts 14 and a plurality of second cross universal joints 13 are further included;

[0068] The support tube 4 extends along the Y direction, and the two support tubes 4 are respectively arranged from the outside close to the two wind grid bars 3 located at the edge;

[0069] The plurality of transmission bearings 9 are divided into two groups, and the plurality of transmission bearings 9 in the same group are arranged at intervals along the Y direction on the top surface of one of the support tubes 4;

[0070] One end of the second connecting shaft 14 is fitted with the transmission wheel 85 , and the other end of the second connecting shaft 14 passes through the transmission bearing 9 and is connected to one end of the second cross universal joint 13 , and the other ends of the two second cross universal joints 13 are respectively connected to the two ends of the flexible shaft 11 .

[0071] like Figure 4 and Figure 5 As shown, when the curvature of the glass to be prepared is greater than the bendability of the soft shaft 11, the bending mechanism 7 drives multiple wind grid bars 3 to bend and continuously increases the curvature to achieve the curvature required by the process; since the bendability of the soft shaft 11 is limited, if the second cross universal joint 13 is not used, the two ends of the soft shaft 11 are respectively rigidly connected to the other ends of the two second connecting shafts 14 in the installation structure, or the two ends of the soft shaft 11 are respectively inserted into the installation structure of the two transmission wheels 85, the flexible shaft 11 will be insufficient in its bendability, and the flexible shaft 11 will hold multiple wind grid bars 3 and cannot continue to bend, causing the bending mechanism to drive the multiple wind grid bars 3 to become stuck during the period of continuously increasing curvature, thereby hindering the operation of the bending mechanism 7 to drive the multiple wind grid bars 3 to bend.

[0072] Therefore, the two ends of the flexible shaft 11 are respectively connected to the two second connecting shafts 14 inserted into the two transmission wheels 85 through two second cross universal joints 13, so that the bending mechanism can drive the bending of multiple wind grid bars 3 without being restricted by the bendability of the flexible shaft 11, thereby avoiding the occurrence of the above phenomenon.

[0073] Furthermore, it also includes a connecting plate 15;

[0074] One end of the support tube 4 is connected to one end of the adjacent wind grid bar 3 through the connecting plate 15 .

[0075] like Figure 4 and Figure 5 As shown, one end of the support tube 4 and one end of the adjacent wind grid bar 3 are connected together by a connecting plate 15 , so that the support tube 4 can bend and move along with the adjacent wind grid bar 3 .

[0076] Preferably, the outer peripheral surface of the conveying wheel 12 is wrapped with aramid heat insulation cotton.

[0077] The conveying wheel 12 is made of metal, and the outer surface of the conveying wheel 12 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 12 .

[0078] Furthermore, a plurality of blowing boxes 6 are installed between two adjacent flexible shafts 11;

[0079] The blowing boxes 6 extend along the Y-axis direction, and the plurality of blowing boxes 6 located between two adjacent flexible shafts 11 are arranged at intervals along the X-direction.

[0080] like Figure 4-6 As shown, cooling air can be blown to the tempered glass after bending through the blowing box 6, so that the tempered glass can be quenched and tempered.

[0081] Furthermore, the support base 2 further includes two shaft sleeves 24;

[0082] Two ends of the connecting seat 22 are respectively provided with two shaft sleeves 24;

[0083] The two ends of the connecting seat 22 are rotatably mounted in the two rotating chambers 210 through the corresponding shaft sleeves 24;

[0084] The shaft sleeve 24 is provided with a limiting ring 241;

[0085] The limiting ring 241 surrounds the circumferential edge of the shaft sleeve 24 on a side close to the rotating cavity 221 . The limiting ring 241 is used to abut against the edge of the corresponding rotating cavity 210 .

[0086] like Figure 7 and Figure 8 As shown, the sleeve 24 can reduce the rigid contact and friction between the two ends of the connecting seat 22 and the rotating cavity 210, and improve the rotation flexibility and service life of the two ends of the connecting seat 22.

[0087] like Figure 8As shown, the limiting ring 241 can improve the installation stability of the shaft sleeve 24 and prevent the shaft sleeve 24 from passing through the rotating cavity 210 and getting loose during operation.

[0088] Furthermore, the connecting seat 22 includes two mirror-symmetrical halves, and the rotating cavity 221 is formed by closing two semicircular grooves symmetrically distributed in the upper and lower parts.

[0089] like Figure 7 and Figure 8 As shown, the connecting seat 22 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 spherical bearing 23.

[0090] Preferably, the shaft sleeve 24 is made of polytetrafluoroethylene.

[0091] The shaft sleeve 24 made of polytetrafluoroethylene has better wear resistance and service life.

[0092] In summary, if Figure 1-5 In the embodiment of the utility model shown, the wind grid bar transmission structure adapted to step-by-step bending and tempering, the two ends of the linkage rod 84 are respectively connected to the two first cross universal couplings 86 and the two first connecting shafts 87 through the connection structure. During the output and step-by-step bending and forming of the glass, the lower bending arc mechanism 7 at the input end can be kept in a horizontal state, so that the glass can be smoothly input to the top of multiple wind grid bars 3 through the soft shaft transmission roller 1, and the glass can be smoothly completed in steps above the multiple wind grid bars 3. It can also prevent the lower bending arc mechanism 7 at the input end from twisting and deformation during the step-by-step forming process.
