Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a heating device and method for producing ultra-thin glass. Background Technology

[0002] Existing heating devices for ultra-thin glass production typically employ a structure combining forced convection and radiant heating. They generate heat through electric heating elements or gas combustion, and use devices such as high-temperature jet pipes and hot gas nozzles to achieve directional heating. Their core function is to uniformly raise the glass temperature to the softening point (approximately 650°C), eliminating internal stress. At the same time, by combining dynamic transmission (such as roller conveyor) with a fixed heating area, they ensure that the glass is heated evenly during movement, preventing deformation. Ultimately, this improves the flatness, strength, and light transmittance of the glass, meeting the production requirements of high-precision products such as display substrates and cover glass.

[0003] Existing glass production heating equipment typically includes a guiding mechanism to move the glass as it enters the equipment. These mechanisms usually employ ceramic rollers and side guide wheels. The ceramic rollers, made of high-purity alumina ceramic, have a smooth surface and are heat-resistant. A synchronous transmission system moves the glass horizontally, ensuring a stable trajectory during heating and preventing uneven heating due to friction or misalignment. The side guide wheels, installed on both sides of the furnace, are made of heat-resistant material with a low coefficient of friction. An elastic clamping device adjusts their spacing to precisely constrain the glass edge position, preventing lateral displacement during the high-temperature softening stage.

[0004] When the material guiding mechanism of the existing glass production heating device guides the glass, although it limits and guides the glass of different sizes on both sides through the corresponding mechanism, the heating area of ​​the entire heating device is mostly fixed. As a result, when heating some small glass raw materials, the heating area is easily too large, and the heat cannot be concentrated quickly. Therefore, it is impossible to adjust the heating area according to the actual size of the glass to be processed in actual operation. Summary of the Invention

[0005] The purpose of this invention is to provide a heating device and method for producing ultra-thin glass, which can adjust the heating area according to the actual size of the glass to be processed by the provided components, so as to ensure the heat concentration as much as possible for glass of different sizes to be processed, and thus make the heating efficiency higher during actual processing.

[0006] To achieve the above objectives, the present invention provides a heating device and method for producing ultra-thin glass, including a processing main frame and a top-blowing heating mechanism, wherein the top-blowing heating mechanism is fixedly installed on the inner top wall of the processing main frame, and also includes processing components;

The two movable sidewalls are slidably installed on the left and right sides of the processing main frame, respectively. The left and right sides of the movable sidewalls are slidably connected to the two support partitions. The two sets of position adjustment components are respectively arranged on both sides of the processing main frame to drive the two movable sidewalls. The movement of the movable sidewalls changes the actual heating space size inside the processing main frame. The transmission component is arranged inside the processing main frame to guide and convey the glass to be processed into the processing main frame.

[0008] The position adjustment component includes a guide bracket, sliding plates, a pusher, a dual-drive lead screw, and a lead screw drive mechanism.

[0011] The adjustment components include a fixed truss, inner clamping wheel frames, and outer clamping wheel frames. The fixed truss is fixedly installed inside the main processing frame. Two movable sidewalls pass through the two sides of the fixed truss. The fixed truss corresponds one-to-one with the cross transmission rod and is located on one side of the cross transmission rod. Two inner clamping wheel frames and two outer clamping wheel frames are slidably arranged on each fixed truss. The two inner clamping wheel frames cooperate with two transmission ceramic wheels arranged inside the cross transmission rod, and the two outer clamping wheel frames cooperate with two transmission ceramic wheels arranged outside the cross transmission rod.

[0012] The adjustment component further includes an inner drive double-ended lead screw, an outer drive double-ended lead screw, and threaded hole sleeves.

The inner drive double-ended lead screw is threadedly connected to two inner clamping wheel frames on both sides and passes through two outer clamping wheel frames. The outer drive double-ended lead screw is threadedly connected to two outer clamping wheel frames on both sides and passes through two inner clamping wheel frames. Multiple threaded hole sleeves are rotatably disposed on the movable sidewall plate, passing through the movable sidewall plate. The number of threaded hole sleeves is the sum of the number of inner drive double-ended lead screws and outer drive double-ended lead screws. Each threaded hole sleeve is threadedly connected to one of the multiple inner drive double-ended lead screws and multiple outer drive double-ended lead screws in a one-to-one correspondence.

[0013] The adjustment components further include an outer worm gear, a linkage worm, and a worm drive box.

[0017] The width of the glass to be processed is measured and estimated, and then the size of the heating space inside the main processing frame is adjusted based on the measurement and estimation results;

[0018] When adjusting the internal heating space of the main processing frame, the movable sidewalls on the left and right sides of the main processing frame are first driven by the position adjustment component, and the actual heating space size inside the main processing frame is changed by moving the movable sidewalls.

[0019] Then, the corresponding transmission structure of the transmission component is adjusted by the adjustment component set inside the transmission component, so as to adapt it to the actual heating space size after adjustment;

[0020] After the adjustment is completed, the glass to be processed is placed on the support partition at the feed port of the main processing frame, and then conveyed into the main processing frame through the transmission component set inside the main processing frame;

[0022] This invention discloses a heating device and method for producing ultra-thin glass. In actual operation, the width of the glass to be processed is measured and estimated. Based on the measurement and estimation results, the size of the heating space inside the processing main frame is adjusted. When adjusting the heating space inside the processing main frame, the movable sidewalls on the left and right sides of the processing main frame are first driven by the position adjustment component. The movement of the movable sidewalls changes the actual heating space size inside the processing main frame. Then, the corresponding transmission structure of the transmission component is adjusted by the adjustment component inside the transmission component, thereby adjusting the heating space. The actual heating space size is adapted after adjustment. After adjustment, the glass to be processed is placed on the support partition at the feed port of the main processing frame. Then, it is conveyed into the main processing frame through the transmission component set inside the main processing frame. The glass to be processed in the main processing frame is heated by the top blowing heating mechanism in conjunction with the corresponding heating auxiliary mechanism. This realizes that the heating area can be adjusted according to the actual size of the glass to be processed by the set components, so as to ensure the heat concentration as much as possible for glass of different sizes, and make the heating efficiency higher during actual processing.

Detailed Implementation

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Please see Figures 1 to 10This invention provides a heating device and method for ultra-thin glass production: It includes a processing main frame 101, a top-blowing heating mechanism 102, and processing components. The processing components include a supporting partition 103, a movable side wall plate 104, a position adjustment component, and a transmission component. The position adjustment component includes a guide bracket 201, a sliding plate 202, a pushing component 203, a double-drive lead screw 204, and a lead screw drive mechanism 205. The transmission component includes a cross transmission rod 301, a slotted sleeve 302, a transmission ceramic wheel 303, a rotating component, and an adjusting component. The rotating component includes a transmission bevel gear 401, a rotating shaft 402, a rotating bevel gear 403, and a rotating shaft drive box 404. The adjusting component includes a fixed truss 501, an inner clamping wheel frame 502, and an outer... The clamping wheel frame 503, the adjustment component further includes an inner drive double-ended lead screw 504, an outer drive double-ended lead screw 505 and a threaded hole rotating sleeve 506, the adjustment component also includes an outer worm gear 507, a linkage worm 508 and a worm drive box 509. The aforementioned solution solves the problem that when the guiding mechanism of the existing glass production heating device guides the glass, although it limits and guides the glass to be processed on both sides of different sizes through the corresponding mechanism, the heating area of ​​the entire heating device is mostly fixed. As a result, when heating some small-sized glass raw materials, the heating area is easily too large, and the heat cannot be concentrated quickly. Therefore, it is impossible to adjust the heating area according to the actual size of the glass to be processed in actual operation.

[0039] Furthermore, the top-blowing heating mechanism 102 is fixedly installed on the inner top wall of the main frame, the two supporting partitions 103 are respectively fixedly installed on the front and rear sides inside the processing main frame 101, the two movable side wall plates 104 are respectively slidably installed on the left and right sides inside the processing main frame 101, the left and right sides of the movable side wall plates 104 are respectively slidably connected to the two supporting partitions 103, the two sets of position adjustment components are respectively arranged on both sides of the processing main frame 101 for driving the two movable side wall plates 104, and the transmission component is arranged inside the processing main frame 101 for guiding and conveying the glass to be processed into the processing main frame 101.

[0040] Specifically, the top of the processing main frame 101 is provided with a corresponding top-blowing heating mechanism 102. The top-blowing heating mechanism 102 consists of a hot air blowing structure and an internal temperature detection structure, so as to heat the surface of the glass to be processed that enters the processing main frame 101 and monitor the temperature inside the processing main frame 101.

[0041] The feed inlet and discharge outlet of the main processing frame 101 are both equipped with support partitions 103. The support partitions 103 are adapted to the sliding grooves on both sides of the two movable side wall plates 104. The two movable side wall plates 104 divide the internal area of ​​the main processing frame 101 into three sections. The area between the two movable side wall plates 104 is the heating working area, while the area between the two movable side wall plates 104 and the two side walls of the main processing frame 101 is the adjustment area. As the two movable side wall plates 104 slide, the adjustment area on both sides continuously increases, and the heating working area between the two movable side wall plates 104 becomes smaller, and vice versa. Thus, the size of the internal heating area of ​​the main processing frame 101 can be changed by driving the two movable side wall plates 104.

[0042] In actual operation, the width of the glass to be processed is measured and estimated. Based on the measurement and estimation results, the size of the heating space inside the processing main frame 101 is adjusted. When adjusting the heating space inside the processing main frame 101, the movable sidewalls 104 on the left and right sides of the processing main frame 101 are first driven by the position adjustment component. The movement of the movable sidewalls 104 changes the actual heating space size inside the processing main frame 101. Then, the corresponding transmission structure of the transmission component is adjusted by the adjustment component inside the transmission component, thereby adjusting the actual heating space size. After the size is matched and the adjustment is completed, the glass to be processed is placed on the support partition 103 at the feed port of the main processing frame 101. Then, it is conveyed into the main processing frame 101 by the transmission component set inside the main processing frame 101. The glass to be processed into the main processing frame 101 is heated by the top blowing heating mechanism 102 in conjunction with the corresponding heating auxiliary mechanism. This realizes that the heating area can be adjusted according to the actual size of the glass to be processed by the provided components, so as to ensure the heat concentration as much as possible for glass of different sizes, and thus the heating efficiency is higher during actual processing.

[0043] Furthermore, the guide bracket 201 is fixedly connected to the main processing frame 101 and is located on the side of the main processing frame 101 near the movable side wall plate 104; the sliding plates 202 are slidably installed on both sides of the guide bracket 201; the sliding plates 202 are connected to the movable side wall plate 104 through the pusher 203, and the pusher 203 is rotatably connected to the sliding plates 202 and the movable side wall plate 104 on both sides respectively; the dual-drive screw 204 is rotatably installed on the guide bracket 201, and the dual-drive screw 204 is threadedly connected to the two sliding plates 202 on both sides respectively; the screw drive mechanism 205 is connected to the dual-drive screw 204 and is disposed on the main processing frame 101 for driving the dual-drive screw 204.

[0044] In this embodiment, guide brackets 201 are fixedly installed on the left and right inner side walls of the processing main frame 101. Two sliding plates 202 are slidably arranged on the guide brackets 201. Each sliding plate 202 is connected to the adjacent movable side wall plate 104 through a pusher 203. The pusher 203 can rotate at the connection point. At the same time, the two sliding plates 202 are also driven by a dual-drive screw 204 arranged on the guide brackets 201. The threads on both sides of the dual-drive screw 204 have opposite directions.

[0045] When the dual-drive lead screw 204 rotates, the two sliding plates 202 connected to both sides of the dual-drive lead screw 204 will expand to both sides or move closer together under the action of the dual-drive lead screw 204. In this way, the pusher 203, which is slidably coupled to the guide bracket 201 by the two sliding plates 202, can drive the corresponding movable side wall plate 104.

[0046] As the two sliding plates 202 expand outwards, the pusher 203 connected to the sliding plates 202 continuously pushes out the movable sidewall 104, causing the movable sidewall 104 to move further away from the guide bracket 201. Conversely, as the two sliding plates 202 move closer together, the pusher 203 connected to the sliding plates 202 continuously pulls the movable sidewall 104 together, causing the movable sidewall 104 to move closer to the guide bracket 201, thereby achieving corresponding driving of the movable sidewall 104 on both sides.

[0047] Both sides of the dual-drive lead screw 204 are driven by the corresponding lead screw drive mechanism 205, which is composed of a corresponding gear set and a drive element. The drive element works in conjunction with the corresponding gear set to drive the corresponding rod.

[0048] Furthermore, multiple cross-shaped transmission rods 301 are rotatably mounted within the machining main frame 101; multiple slotted sleeves 302 are rotatably mounted on the movable side wall plate 104, the slotted sleeves 302 penetrating the movable side wall plate 104 and correspondingly engaging with each cross-shaped transmission rod 301; each cross-shaped transmission rod 301 is fitted with four transmission ceramic wheels 303; the rotating component is located on one side of the machining main frame 101 and is used to synchronously drive the multiple cross-shaped transmission rods 301; the adjusting component is connected to the machining main frame 101 and is used to adjust the engagement position of the four transmission ceramic wheels 303 mounted on the cross-shaped transmission rods 301.

[0049] Furthermore, each of the cross transmission rods 301 is fixedly mounted with a transmission bevel gear 401 on its side; the rotating shaft 402 is rotatably mounted on the side of the machining main frame 101 near the transmission bevel gear 401; the rotating bevel gear 403 is arranged in a one-to-one correspondence with the transmission bevel gear 401, and multiple rotating bevel gears 403 are fixedly sleeved on the rotating shaft 402; the rotating shaft drive box 404 is arranged on one side of the machining main frame 101 and is used to drive the rotating shaft 402.

[0050] In this embodiment, when in use, the processing main frame 101 is provided with a plurality of cross transmission rods 301. Each cross transmission rod 301 mainly consists of a cross rod body and cylindrical components connecting both ends. Each cross transmission rod 301 is fitted with a transmission ceramic wheel 303. The cross groove in the middle of the transmission ceramic wheel 303 is adapted to the cross rod body of the cross transmission rod 301.

[0051] Multiple slots 302 are provided on the two movable sidewalls 104 for cooperating with the cross transmission rod 301. The slots 302 are provided with corresponding cross through holes to cooperate with the cross transmission rod 301, so that the rotation of the cross transmission rod 301 and the movement of the movable sidewalls 104 will not interfere with each other.

[0052] Each of the cross transmission rods 301 has a transmission bevel gear 401 fixed to its outer side. The transmission bevel gear 401 meshes with the rotating bevel gear 403 set on the rotating shaft 402. All the rotating bevel gears 403 are fixed on the same rotating shaft 402. The rotating shaft 402 is driven by the rotating shaft drive box 404. The rotating shaft drive box 404 consists of a gear set and a drive element. The drive element cooperates with the gear set to drive the rotating shaft 402. When the rotating shaft 402 rotates, the multiple rotating bevel gears 403 set on the rotating shaft 402 will drive the corresponding transmission bevel gears 401 and the cross transmission rods 301 to rotate synchronously. In turn, the cross transmission rods 301 drive the multiple corresponding transmission ceramic wheels 303 to rotate synchronously, so as to convey the glass to be processed into the processing main frame 101 through the rotation of the transmission ceramic wheels 303.

[0053] Furthermore, the fixed truss 501 is fixedly installed inside the processing main frame 101. Two movable sidewalls 104 pass through both sides of the fixed truss 501. The fixed truss 501 corresponds one-to-one with the cross transmission rod 301. The fixed truss 501 is located on one side of the cross transmission rod 301. Two inner clamping wheel frames 502 and two outer clamping wheel frames 503 are slidably arranged on each fixed truss 501. The two inner clamping wheel frames 502 cooperate with the two transmission ceramic wheels 303 arranged inside the cross transmission rod 301. The two outer clamping wheel frames 503 cooperate with the two transmission ceramic wheels 303 arranged outside the cross transmission rod 301.

[0054] Furthermore, each of the fixed trusses 501 is rotatably mounted with an inner drive double-ended lead screw 504 and an outer drive double-ended lead screw 505. The inner drive double-ended lead screw 504 is threadedly connected to two inner clamping wheel frames 502 on both sides and passes through two outer clamping wheel frames 503. The outer drive double-ended lead screw 505 is threadedly connected to two outer clamping wheel frames 503 on both sides and passes through two inner clamping wheel frames 502. A plurality of threaded hole rotating sleeves 506 are rotatably provided on the movable side wall plate 104. The threaded hole rotating sleeves 506 pass through the movable side wall plate 104. The number of threaded hole rotating sleeves 506 is the sum of the number of inner drive double-ended lead screws 504 and outer drive double-ended lead screws 505. The threaded hole rotating sleeves 506 are threadedly connected to the plurality of inner drive double-ended lead screws 504 and the plurality of outer drive double-ended lead screws 505 in a one-to-one correspondence.

[0055] Furthermore, an outer worm gear 507 is fixedly installed on one side of each of the internal drive double-ended lead screws 504 and the external drive double-ended lead screws 505; two linkage worm gears 508 are rotatably installed on the side of the machining main frame 101 near the outer worm gears 507, and the two linkage worm gears 508 respectively cooperate with the outer worm gears 507 installed on the multiple internal drive double-ended lead screws 504 and the multiple outer worm gears 507 installed on the multiple external drive double-ended lead screws 505; two worm drive boxes 509 are respectively disposed on one side of the machining main frame 101, and the two worm drive boxes 509 are respectively used to drive the two linkage worm gears 508 to rotate.

[0056] In this embodiment, the inner clamping wheel frame 502 and the outer clamping wheel frame 503 provided on the fixed truss 501 are respectively adapted to the four transmission ceramic wheels 303 provided on the cross transmission rod 301. The two inner clamping wheel frames 502 on each fixed truss 501 cooperate with the two transmission ceramic wheels 303 located in the middle of the cross transmission rod 301, while the two outer clamping wheel frames 503 cooperate with the two transmission ceramic wheels 303 located on the outside of the cross transmission rod 301.

[0057] The movement of the inner clamping wheel frame 502 and the outer clamping wheel frame 503 on both sides of the fixed truss 501 drives the corresponding transmission ceramic wheel 303 to move on the cross transmission rod 301, thereby adjusting the specific mating position of the four transmission ceramic wheels 303. For example, by sliding the inner clamping wheel frame 502 on both sides, the mating distance of the two inner transmission ceramic wheels 303 can be adjusted, and by sliding the outer clamping wheel frame 503 on both sides, the mating distance of the two outer transmission ceramic wheels 303 can be adjusted. This allows the operator to adjust the mating position of the corresponding conveying mechanism according to the actual size of the glass to be processed after adjusting the size of the entire heating area, so that glass of different sizes can be conveyed stably and quickly.

[0058] Each of the fixed trusses 501 is equipped with an inner drive double-ended lead screw 504 and an outer drive double-ended lead screw 505. The driving principle of the inner drive double-ended lead screw 504 and the outer drive double-ended lead screw 505 is the same as that of the double drive lead screw 204. The threads on both sides of the inner drive double-ended lead screw 504 and the outer drive double-ended lead screw 505 are arranged in opposite directions. The inner drive double-ended lead screw 504 is used to cooperate with the inner clamping wheel frame 502 arranged on both sides of the fixed truss 501. The external drive double-ended lead screw 505 is used to cooperate with the external clamping wheel frame 503 set on both sides of the fixed truss 501. The internal clamping wheel frame 502 and the external clamping wheel frame 503 are both provided with corresponding through holes. The through hole provided in the internal clamping wheel frame 502 is used for the external drive double-ended lead screw 505 to pass through directly, and the external clamping wheel frame 503 is used for the internal drive double-ended lead screw 504 to pass through directly, so as to avoid the uncooperative screws affecting the automatic movement of the frame.
