[0002] As people are constantly pursuing beauty, the appearance of televisions has been greatly improved compared to before. At this stage, tempered glass TV back panels are becoming more and more popular among the public. The tempered glass TV back panel is a whole piece of tempered glass with a curved portion at the edge, which makes the entire TV more three-dimensional visually and more in line with people's aesthetic standards.

[0003] However, the current equipment for producing curved tempered glass uses a pre-made mold to shape the heated and softened glass and then cool it to bend it into shape. This equipment takes a long time to form the finished product. In addition, since the shape is determined by the mold, when producing glass with different thicknesses and curvature parameters, corresponding molds need to be produced. This mold is inconvenient to replace, which increases production costs and reduces production efficiency. Summary of the invention

[0021] The lifting unit includes a lifting device and a connecting device, the lifting device includes a plurality of lifts, and the connecting device includes a lifting frame and a support rod;

[0022] The elevators are distributed at intervals on the outer wall of the heating furnace frame, and a lifting frame is provided between two adjacent elevators. Both ends of the lifting frame are vertically connected to the support rods, and one end of the support rod away from the lifting frame is connected to the elevator gear. The elevator drives the support rod to reciprocate up and down in the vertical direction through its own gear;

[0023] The lifting frame is connected to the roller shaft of the upper roller shaft group.

[0024] For example, the lifting module also includes a transmission unit, which includes an upper driving wheel, an upper drive wheel and an adjusting device, and the adjusting device includes an adjusting seat and an adjusting wheel sliding in the adjusting seat, the upper driving wheel, the upper drive wheel and the adjusting wheel are arranged in a closed loop of the same chain or belt, and the upper drive wheel is used to drive the roller shaft of the upper roller shaft group to rotate.

[0025] It is worth noting that the connecting device further comprises a plurality of roller bearing seats, the roller bearing seats correspond to the rollers of the upper roller set one by one and are rotatably connected via bearings, and the outer wall of the roller bearing seat is fixedly connected to the lifting frame;

[0026] The elevator is horizontally arranged below the upper roller assembly, one end of the support rod away from the lifting frame vertically penetrates the elevator, and the surface of the support rod is provided with a thread meshing with a gear in the elevator;

[0027] The lifting device also includes a commutator and a lifting drive mechanism, the output end of the commutator is connected to the input end of the hoist, the input end of the commutator is connected to the output end of the lifting drive mechanism, and the lifting drive mechanism is vertically arranged on the outer wall of the heating furnace frame.

[0028] Optionally, the regulating device further comprises a regulating cylinder, and the regulating cylinder is arranged on the heating furnace frame;

[0029] The adjusting device further comprises an adjusting block, the adjusting seat is provided with a guide rail, one side of the adjusting block is slidably connected to the guide rail, and the other side of the adjusting block is rotatably connected to the adjusting wheel;

[0031] Specifically, one end of the upper fixed roller, the upper forming roller and the upper stabilizing roller is provided with an upper driven wheel, the upper driving wheel is transmission-connected with the upper driven wheel of the upper forming roller at the end, and all the upper driven wheels of the upper fixed roller, the upper forming roller and the upper stabilizing roller are transmission-connected by a chain or belt;

[0032] The transmission unit further comprises an upper driving mechanism, and an output end of the upper driving mechanism is connected to the upper driving wheel.

[0033] The beneficial effects of the present invention are as follows: the heated and softened glass passes through the forming wheels of the lower forming roller with a gradually increasing inclination angle of the bending and tempered glass production equipment in sequence, and is positioned by the forming wheels of the upper forming roller that complement the inclination angle of the forming wheels of the lower forming roller, so that the edge of the glass is gradually bent, and finally a preset bending angle is formed, which greatly reduces the working hours for forming the bent glass.

[0034] The tilt angle a is the angle of the ray formed by the one end of the forming wheel of the lower forming roller connected to the shaft body extending to the other end, and the tilt angle b is the angle of the ray formed by the one end of the forming wheel of the upper forming roller connected to the shaft body extending to the other end. During processing, the glass enters from the feed port of the heating furnace, and the lower forming roller drives the glass forward. While moving forward, the glass is heated by the heating wire in the heating furnace to soften the glass. Then the edge of the glass will bend with the tilt of the forming wheel of the lower forming roller, and the positioning of the forming wheel of the upper forming roller makes the glass maintain a specified bending angle. As the tilt angle a of the forming wheel of the lower forming roller increases, the bending angle of the glass increases continuously and finally reaches the preset bending angle. Compared with the equipment that bends the glass by cooling after the mold is finalized, the production equipment of bent tempered glass can make the glass reach the preset bending angle without the finalization link because the bending angle of the glass is gradually fine-tuned to bend the glass, thereby reducing the processing time and improving efficiency.

[0035] When processing glass of different thicknesses, the lifting unit drives all the upper forming rollers to move at the same time, so that the upper forming rollers move up and down in the vertical direction, thereby adjusting the distance between the upper forming rollers and the lower forming rollers so that the distance is consistent with the thickness of the glass. In addition, when the glass is accidentally broken during the processing, the upper forming rollers can be lifted by the lifting unit to facilitate the cleaning of the glass fragments in the heating furnace.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] Combine the following Figures 1 to 14 , describing a production device for curved tempered glass according to an embodiment of the present invention, comprising a processing module 1 and a lifting module 3 arranged on a heating furnace frame;

[0056] The processing module 1 includes a forming section 11, and the forming section 11 is provided with a plurality of upper forming rollers 111 and lower forming rollers 112, and the upper forming rollers 111 and the lower forming rollers 112 are arranged one by one in an upper and lower correspondence;

[0057] The upper forming roller 111 and the lower forming roller 112 each include a shaft body 1111 and a forming wheel 1112, wherein the forming wheel 1112 is disposed at one end of the shaft body 1111;

[0058] Each pair of the forming wheels 1112 of the upper forming roller 111 and the forming wheels 1112 of the lower forming roller 112 arranged up and down are both truncated cone structures with complementary inclination angles b and a, and the inclination angle a of the forming wheels 1112 of the lower forming roller 112 gradually increases from the feeding direction to the discharging direction;

[0059] The lifting module 3 includes a lifting unit 32 , and the lifting unit 32 is used to lift all the upper forming rollers 111 .

[0060] The heated and softened glass passes through the forming wheel 1112 of the lower forming roller 112 of the bending and tempered glass production equipment in sequence, and is positioned by the forming wheel 1112 of the upper forming roller 111, which is complementary to the inclination angle of the forming wheel 1112 of the lower forming roller 112, so that the edge of the glass is gradually bent, and finally a preset bending angle is formed, which greatly reduces the working time of forming the bent glass. The bending and tempered glass production equipment can adjust the height of the upper forming roller 111 through the lifting unit 32 to meet the needs of glass of different thicknesses. When producing glass of different thicknesses, there is no need to replace parts, thereby improving production efficiency and reducing production costs.

[0061] like Figure 2-4As shown, the inclination angle a is the angle of the ray formed by the one end of the forming wheel 1112 of the lower forming roller 112 connected to the shaft body 1111 extending to the other end, and the inclination angle b is the angle of the ray formed by the one end of the forming wheel 1112 of the upper forming roller 111 connected to the shaft body 1111 extending to the other end. During processing, the glass enters from the feed port of the heating furnace, and the lower forming roller 112 drives the glass forward. While moving forward, the glass is heated by the heating wire in the heating furnace to soften the glass. Then the edge of the glass will bend with the inclination of the forming wheel 1112 of the lower forming roller 112, and the positioning of the forming wheel 1112 of the upper forming roller 111 keeps the glass at a specified bending angle. As the inclination angle a of the forming wheel 1112 of the lower forming roller 112 increases, the bending angle of the glass increases continuously, and finally reaches the preset bending angle. Compared with the equipment that bends the glass by cooling the mold after shaping, the production equipment for curved tempered glass bends the glass by gradually fine-tuning the bending angle of the glass. It can make the glass reach a preset bending angle without the need for a shaping step, thereby reducing processing time and improving efficiency.

[0062] When processing glass of different thicknesses, the lifting unit 32 drives all the upper forming rollers 111 to move at the same time, so that the upper forming rollers 111 move up and down in the vertical direction, thereby adjusting the spacing between the upper forming rollers 111 and the lower forming rollers 112 so that the spacing is consistent with the thickness of the glass. In addition, when the glass is accidentally broken during the processing, the upper forming rollers 111 are lifted by the lifting unit 32, which can facilitate the cleaning of the glass fragments in the heating furnace.

[0063] In some embodiments, the molding wheel 1112 includes a first shaft core 1113 and a molding oblique roller surface 1115 wrapped around the first shaft core 1113 , and the first shaft core 1113 is detachably connected to the shaft body 1111 ;

[0064] The shaft body 1111 includes a second shaft core 1114 and a formed flat roller surface 1116 wrapped around the outside of the second shaft core 1114. The first shaft core 1113 and the second shaft core 1114 are detachably connected. The formed flat roller surface 1116 is a cylindrical structure. The diameter of the formed flat roller surface 1116 is equal to the diameter of one end of the formed inclined roller surface 1115 connected to the shaft body 1111.

[0065] Glass can be processed into different bending angles by simply replacing the forming wheel 1112. Compared with replacing the entire roller, replacing the forming wheel 1112 is simpler and faster.

[0066] When the diameter of the forming flat roller surface 1116 is equal to the diameter of the bottom surface of the forming inclined roller surface 1115 and the end connected to the shaft body 1111, no bulge will be formed at the junction of the forming flat roller surface 1116 and the forming inclined roller surface 1115, but a smooth transition surface will be formed. When the glass passes through, no bulge will be formed or it will get stuck, so it can be transported smoothly.

[0067] The flat roller surface 1116 of the lower forming roller 112 is used to transport the glass, and the flat roller surface 1116 of the upper forming roller 111 is used to press the glass located at the lower forming roller 112, so that the thickness of each position of the processed glass is the same. During operation, the lower forming roller 112 rotates around its own axis, and the flat roller surface 1116 of the lower forming roller 112 also rotates with it, and the glass is transported forward. At this time, the upper forming roller 111 also rotates at the same angular velocity, thereby avoiding the deviation of the angular velocities of the upper forming roller 111 and the lower forming roller 112 and scratching the glass.

[0068] For example, the tolerance of the inclination angle of the forming wheels 1112 of two adjacent lower forming rollers 112 is a fixed value.

[0069] That is, the difference in the inclination angles of the forming wheels 1112 of every two adjacent lower forming rollers 112 is a fixed value, forming an arithmetic progression, so that the above structure can bend the glass at a fixed rate of change. When the glass transitions from one lower forming roller 112 to the next lower forming roller 112, cracks will not appear in the bent part due to the sudden increase or decrease in the rate of change of the inclination angle, thereby improving the quality of glass forming.

[0070] It is worth noting that if Figure 11-14 As shown, the processing module 1 further includes a fixed section 12 and a stabilizing section 13, and the fixed section 12, the forming section 11 and the stabilizing section 13 are sequentially arranged in the heating furnace frame from the direction of feeding to the direction of discharging;

[0071] The fixed section 12 is provided with a plurality of upper fixed rollers 121 and lower fixed rollers 122, and the diameters of the upper fixed rollers 121 and lower fixed rollers 122 are equal to the diameter of the forming flat roller surface 1116 of the shaft body 1111 of the upper forming roller 111 or the lower forming roller 112;

[0072] The stabilizing section 13 is provided with a plurality of upper stabilizing rollers 131 and lower stabilizing rollers 132 , and the upper stabilizing rollers 131 and lower stabilizing rollers 132 are used to keep the bending angle of the glass at a fixed angle.

[0073] The fixing section 12 is used to guide the glass into the forming section 11 to prevent the glass from deviating. The structure of the fixing section 12 ensures that there is no height difference between the fixing section 12 and the forming section 11, so that the glass can be transported more stably.

[0074] Since the edge of the glass gradually bends during the transportation of the glass, when the edge at the front end of the glass bends to the predetermined angle, the edge at the rear end of the glass has not yet reached the angle. At this time, the stabilizing section 13 can keep the portion that has reached the predetermined angle at the formed angle, waiting for the edge at the rear end to bend, until the edge of the entire glass is bent to the predetermined angle. Fig.10 The structure of the upper stabilizing roller 131 is consistent with the structure of the upper forming roller 111 at the end, and the structure of the lower stabilizing roller 132 is consistent with the structure of the lower forming roller 112 at the end.

[0075] Alternatively, if Figure 5 and 6 As shown, it also includes a lower driving module 2, and the lower driving module 2 includes a lower driving wheel 211, a lower driven wheel 212, a lower driving wheel set and a driving shaft;

[0076] All of the lower fixed rollers 122, the lower forming rollers 112 and the lower stabilizing rollers 132 form a lower roller group 14;

[0077] The lower driving wheel 211 is transmission-connected with the lower driven wheel 212;

[0078] The outer part of the driving shaft 22 is sleeved with the lower driven wheel 212 and the lower driving wheel group, and the lower driving wheel group includes a plurality of lower driving wheels 213, and the lower driving wheels 213 are arranged up and down and correspond one to one with the roller shafts of the lower roller shaft group 14, and each of the lower driving wheels 213 is drivingly connected with the roller shafts of the lower roller shaft group 14 corresponding thereto.

[0079] During operation, the lower driving wheel 211 rotates, the lower driving wheel 211 drives the lower driven wheel 212 to rotate, and the lower driven wheel 212 drives the driving shaft 22 to rotate, so that all the lower driving wheels 213 sleeved outside the driving shaft 22 rotate, and each lower driving wheel 213 drives the corresponding roller in the lower roller group 14 to rotate, thereby achieving synchronous rotation. The lower driving wheel 211 is driven by the lower driving mechanism 21, and the lower driving mechanism 21 is preferably a motor.

[0080] Specifically, Figure 7-9 As shown, all the upper fixed rollers 121, the upper forming rollers 111 and the upper stabilizing rollers 131 form an upper roller group 15;

[0081] The lifting unit 32 includes a lifting device 321 and a connecting device 322, wherein the lifting device 321 includes a plurality of lifts 3211, and the connecting device 322 includes a lifting frame 3222 and a supporting rod 3221;

[0082] The elevators 3211 are distributed at intervals on the outer wall of the heating furnace frame, and a lifting frame 3222 is provided between two adjacent elevators 3211. Both ends of the lifting frame 3222 are vertically connected to the support rods 3221. One end of the support rod 3221 away from the lifting frame 3222 is connected to the elevator 3211 with a gear. The elevator 3211 drives the support rod 3221 to make reciprocating motion up and down in the vertical direction through its own gear.

[0083] The lifting frame 3222 is connected to the roller shaft of the upper roller shaft group 15.

[0084] The above structure enables the hoist 3211 to be arranged around the heating furnace frame, and all the hoisting frames 3222 to be located at the same horizontal position. When all the hoisting frames 3211 act synchronously, each hoist 3211 pushes its corresponding support rod 3221 to move upward or downward, and the support rod 3221 also drives its corresponding hoisting frame 3222 to move upward or downward. At this time, all the hoisting frames 3222 are synchronously raised or lowered, that is, the rollers of the upper roller set 15 can be kept at the same horizontal position when rising or falling, and an unbalanced state of one side being higher and the other side being lower will not be caused, thereby avoiding crushing of glass due to the unbalanced rollers of the upper roller set 15.

[0085] Preferably, Fig.10 As shown, the lifting module 3 also includes a transmission unit 31, and the transmission unit 31 includes an upper driving wheel 311, an upper driving wheel 312 and an adjusting device 313. The adjusting device 313 includes an adjusting seat 3131 and an adjusting wheel 3132 sliding in the adjusting seat 3131. The upper driving wheel 311, the upper driving wheel 312 and the adjusting wheel 3132 are arranged in a closed loop of the same chain or belt, and the upper driving wheel 312 is used to drive the roller shaft of the upper roller shaft group 15 to rotate.

[0086] The upper driving wheel 311 rotates to drive the upper driving wheel 312 to rotate, and then the upper driving wheel 312 drives the roller of the upper roller set 15 to rotate. The adjusting wheel 3132 is used to tension the chain or belt so that the upper driving wheel 311 can fully contact the upper driving wheel 312. When the lifting frame 3222 lifts the roller of the upper roller set 15, the distance between the upper driving wheel 311 and the upper driving wheel 312 increases. At this time, the adjusting wheel 3132 slides in the adjusting seat 3131 toward the direction close to the upper driving wheel 311 or the upper driving wheel 312, so that the tension between the upper driving wheel 311 and the upper driving wheel 312 can be automatically adjusted, and the chain or belt will not be too tight and broken due to the increase in the distance between the upper driving wheel 311 and the upper driving wheel 312. When the lifting frame 3222 lowers the roller of the upper roller group 15, the distance between the upper driving wheel 311 and the upper driving wheel 312 is shortened. At this time, the adjusting wheel 3132 slides in the adjusting seat 3131 in the direction away from the upper driving wheel 311 or the upper driving wheel 312, so that the tension between the upper driving wheel 311 and the upper driving wheel 312 can be automatically adjusted, and the chain or belt will not fall off due to the shortened distance between the upper driving wheel 311 and the upper driving wheel 312.

[0087] In some embodiments, Figure 8 As shown, the connecting device 322 also includes a plurality of roller bearing seats 3223, the roller bearing seats 3223 correspond to the rollers of the upper roller assembly 15 one by one and are rotatably connected through bearings, and the outer wall of the roller bearing seat 3223 is fixedly connected to the lifting frame 3222;

[0088] The elevator 3211 is horizontally arranged below the upper roller assembly 15, and one end of the support rod 3221 away from the lifting frame 3222 vertically penetrates the elevator 3211, and the surface of the support rod 3221 is provided with a thread meshing with the gear in the elevator 3211;

[0089] The lifting device 321 also includes a commutator 3213 and a lifting drive mechanism 3212, the output end of the commutator 3213 is connected to the input end of the hoist 3211, the input end of the commutator 3213 is connected to the output end of the lifting drive mechanism 3212, and the lifting drive mechanism 3212 is vertically arranged on the outer wall of the heating furnace frame.

[0090] Whether the lifting module 3 drives the rollers of the upper roller set 15 to rise or fall, or when bending the glass, the rollers of the upper roller set 15 can rotate freely on the roller bearing seat 3223. When the lifting frame 3222 rises or falls, the lifting frame 3222 drives the roller bearing seat 3223 to rise or fall, and the roller bearing seat 3223 can drive the corresponding roller of the upper roller set 15 to rise or fall.

[0091] When the gear in the elevator 3211 rotates, the support rod 3221 can be driven to rise or fall through the thread of the support rod 3221 meshing with the gear in the elevator 3211, and the support rod 3221 is not easy to slip during the rising or falling process. When the support rod 3221 moves upward, the lifting frame 3222 also moves upward, thereby achieving the effect of lifting the upper roller assembly 15; when the support rod 3221 moves downward, the lifting frame 3222 also moves downward, thereby achieving the effect of lowering the upper roller assembly 15.

[0092] The commutator 3213 is used to change the direction of the transmission force so that the lifting drive mechanism 3212 can be arranged vertically, making the installation of each device more compact and saving space. The transmission force of the lifting drive mechanism 3212 rotating in the horizontal direction is switched to the transmission force rotating in the vertical direction through the commutator 3213. The transmission force rotating in the vertical direction drives the rotating shaft of the lifting machine 3211 to rotate, and the rotating shaft of the lifting machine 3211 drives the gear of the lifting machine 3211 to rotate, thereby causing the support rod 3221 to rise or fall.

[0093] For example, the regulating device 313 further includes a regulating cylinder 3134, and the regulating cylinder 3134 is disposed on the heating furnace rack;

[0094] The adjusting device 313 further includes an adjusting block 3133. The adjusting seat 3131 is provided with a guide rail. One side of the adjusting block 3133 is slidably connected to the guide rail. The other side of the adjusting block 3133 is rotatably connected to the adjusting wheel 3132.

[0095] The output end of the regulating cylinder 3134 is fixedly connected to the regulating block 3133 .

[0096] When the lifting module 3 drives the upper roller shaft group 15 to rise, the output end of the adjusting cylinder 3134 pushes the adjusting block 3133 to slide on the guide rail of the adjusting seat 3131 toward the direction close to the upper driving wheel 311 or the upper driving wheel 312, thereby driving the adjusting wheel 3132 to slide toward the direction close to the upper driving wheel 311 or the upper driving wheel 312; when the lifting module 3 drives the upper roller shaft group 15 to descend, the output end of the adjusting cylinder 3134 pulls the adjusting block 3133 to slide on the guide rail of the adjusting seat 3131 toward the direction away from the upper driving wheel 311 or the upper driving wheel 312, thereby driving the adjusting wheel 3132 to slide toward the direction away from the upper driving wheel 311 or the upper driving wheel 312.

[0097] It is worth noting that one end of the upper fixed roller 121, the upper forming roller 111 and the upper stabilizing roller 131 is provided with an upper driven wheel 314, the upper driving wheel 312 is transmission-connected with the upper driven wheel 314 of the upper forming roller 111 at the end, and all the upper driven wheels 314 of the upper fixed roller 121, the upper forming roller 111 and the upper stabilizing roller 131 are transmission-connected by a chain or belt.

[0098] The transmission unit 31 further includes an upper driving mechanism 315 , and an output end of the upper driving mechanism 315 is connected to the upper driving wheel 311 .

[0099] like Fig.10 As shown, the rightmost end is the end. When the upper driving wheel 312 rotates, it drives the upper driven wheel 314 of the upper forming roller 111 at the end to rotate, and then the upper driven wheel 314 of the upper forming roller 111 at the end drives all the upper fixed rollers 121, the upper forming roller 111 and the upper stabilizing roller 131 to rotate through a chain or a belt, thereby realizing synchronous rotation of the rollers of the upper roller group 15, avoiding scratches on the glass due to inconsistent rotation angular velocities of the rollers of the upper roller group 15.

[0100] The upper driving mechanism 315 is preferably a motor, and the output end of the upper driving mechanism 315 rotates around its own central axis to drive the upper driving wheel 311 to rotate. The upper driving wheel 311 can transmit the transmission force to the roller shaft of the upper roller shaft group 15 through the upper driving wheel 312 and the upper driven wheel 314 in turn, so that the roller shaft of the upper roller shaft group 15 rotates.
