Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of glass substrate production, and in particular to a glass substrate shaping furnace and a damper opening adjustment device thereof. Background Art
[0002] In the production process of optoelectronic display glass substrates, the raw materials are heated and liquefied in a kiln and stirred and clarified through a platinum channel. They then flow into the shaping furnace and are made into ultra-thin glass substrates through an overflow down-draw method.
[0003] In order to facilitate the precise control of the airflow and temperature field in the furnace body of the shaping furnace, a damper is provided in the shaping furnace to divide the space in the furnace. The damper divides the space in the furnace into two layers, the upper and lower layers. By adjusting the opening and closing degree of the damper through the damper opening adjustment device, the process setting of different temperatures in the upper and lower layers of the furnace can be realized. In the related art, the damper opening adjustment device is usually provided with a thread. For example, the driving mechanism for driving the damper to rotate in the damper adjustment device usually includes a screw nut mechanism. However, due to the high temperature of the damper, the heat of the damper will be transferred to the damper opening adjustment device, and the threads in the damper opening adjustment device are easily bonded by heat, resulting in the failure of the damper opening adjustment device and the inability to adjust the opening of the damper, which affects the normal production of the optoelectronic display glass substrate.

[0014] Optionally, the locking structure further includes an operating handle, wherein the operating handle is connected to a side of the connecting plate facing away from the clamping plate.
[0015] Optionally, a heat insulating piece is provided on the gripping portion.
[0016] According to a second aspect of the present disclosure, a glass substrate shaping furnace is provided, comprising a furnace body, a damper and the damper opening adjustment device as described above, wherein the damper's rotating shaft passes through the furnace body, the adjustment handle of the damper opening adjustment device is arranged on the outside of the furnace body and connected to the damper's rotating shaft, and the lock plate of the damper opening adjustment device is arranged on the outside of the furnace body and mounted on the furnace body.
[0017] Optionally, there are two dampers, and each damper is correspondingly provided with the damper opening adjustment device.
[0018] Through the above technical solution, since the adjustment handle is arranged outside the glass substrate shaping furnace, one end of the adjustment handle is connected to the rotating shaft of the air door, and the other end of the adjustment handle has a gripping portion, in this way, during the production process of the optoelectronic display glass substrate, when it is necessary to adjust the airflow and temperature field in the furnace body of the glass substrate shaping furnace, the operator can hold the gripping portion and rotate the adjustment handle to drive the rotating shaft of the air door to rotate to adjust the opening and closing degree of the air door, thereby realizing the adjustment of the airflow and temperature field in the furnace body of the glass substrate shaping furnace, and the adjustment of the opening and closing degree of the air door of the glass substrate shaping furnace is relatively simple and the adjustment efficiency is relatively high.

DETAILED DESCRIPTION
[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0032] In the present disclosure, unless otherwise specified, the directions or positional relationships indicated by directional words such as "up", "down", "left", and "right" are defined based on the drawing directions shown in the corresponding drawings and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, they cannot be understood as limitations on the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.
[0033] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.
[0034] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0035] like Figures 1 to 5 As shown, according to the first aspect of the present disclosure, a damper opening adjustment device for a glass substrate shaping furnace is provided, comprising an adjustment handle 10, a lock plate 20 and a locking structure 30, wherein the adjustment handle 10 is used to be arranged outside the furnace body of the glass substrate shaping furnace, one end of the adjustment handle 10 is used to be connected to the rotating shaft 50 of the damper 40, and the other end of the adjustment handle 10 has a gripping portion 11, the adjustment handle 10 is used to drive the rotating shaft 50 to rotate, the lock plate 20 is used to be arranged outside the furnace body and installed on the furnace body, and the lock plate 20 is provided with a locking portion 11 to 11. At least three lock holes 21 are arranged at intervals around the rotation axis of the rotating shaft 50. The locking structure 30 includes a locking member 31. The locking member 31 includes two opposite clamping plates 311 and a connecting plate 312 connected between the two clamping plates 311. The two clamping plates 311 and the connecting plate 312 form a U shape. The gap between the two clamping plates 311 is set to allow the adjustment handle 10 to pass through. The ends of the two clamping plates 311 away from the connecting plate 312 are respectively used to be inserted into the two lock holes 21 located on both sides of the adjustment handle 10.
[0036] Through the above technical solution, since the adjustment handle 10 is arranged outside the glass substrate shaping furnace, one end of the adjustment handle 10 is connected to the rotating shaft 50 of the air door 40, and the other end of the adjustment handle 10 has a gripping portion 11. In this way, during the production process of the optoelectronic display glass substrate, when it is necessary to adjust the airflow and temperature field in the furnace body of the glass substrate shaping furnace, the operator can hold the gripping portion 11 and rotate the adjustment handle 10 to drive the rotating shaft 50 of the air door 40 to rotate to adjust the opening and closing degree of the air door 40, thereby realizing the adjustment of the airflow and temperature field in the furnace body of the glass substrate shaping furnace. The opening and closing degree of the air door 40 of the glass substrate shaping furnace is relatively simple to adjust, and the adjustment efficiency is relatively high.
[0037] At the same time, since the above-mentioned air door opening adjustment device is also provided with a lock plate 20 and a locking structure 30, at least three lock holes 21 are provided on the lock plate 20, and the two clamping plates 311 on the locking member 31 can pass through the adjusting handle 10 and be inserted into the lock holes 21 on the lock plate 20. In this way, when the opening and closing degree of the air door 40 of the glass substrate shaping furnace is adjusted, the operator can operate the locking member 31 to make the two clamping plates 311 on the locking member 31 pass through the adjusting handle 10 and insert the two clamping plates 311 into the lock holes 21 on the lock plate 20. The connecting plate 312 on the locking member 31 and the inner walls of the two clamping plates 311 can jointly limit the adjusting handle 10 to prevent the adjusting handle 10 from being displaced, and effectively preventing the adjusting handle 10 from being displaced due to the influence of gravity and external forces (such as vibration, operator's accidental touch) after the opening and closing degree of the air door 40 of the glass substrate shaping furnace is adjusted, resulting in the air door 40 rotating.
[0038] In addition, since in the above-mentioned damper opening adjustment device, at least three locking holes 21 are arranged at intervals around the rotation axis of the damper 40 shaft 50, when the opening and closing degree of the glass substrate shaping furnace damper 40 is adjusted, the operator can insert the two clamping plates 311 on the locking member 31 into the locking holes 21 located at different positions on the locking plate 20 according to the relative position of the adjustment handle 10, to ensure that the locking member 31 can lock the adjustment handle 10 on the locking plate 20.
[0039] Compared with the technical solution in which threads are provided in the damper adjustment device in the related art, the damper opening adjustment device for the glass substrate shaping furnace provided by the present disclosure can adjust the opening and closing degree of the damper 40 by the operator turning the adjustment handle 10, and fix the position of the adjustment handle 10 by the lock plate 20 and the locking member 31. The adjustment of the opening and closing degree of the damper 40 is simple and efficient. In addition, the damper opening adjustment device has a simple structure and does not have threads or other structures, which effectively avoids the occurrence of gluing in the damper opening adjustment device due to the threads or other structures. In other words, compared with the damper opening adjustment device in the related art, the damper opening adjustment device provided by the present disclosure can effectively reduce the occurrence of heat gluing in the damper opening adjustment device while adjusting the opening and closing degree of the damper 40. The present disclosure does not limit the specific positions of the multiple lock holes 21 on the lock plate 20. As long as the two clamping plates 311 on the locking member 31 can be inserted into different lock holes 21 when the position of the adjustment handle 10 on the lock plate 20 is changed, the adjustment handle 10 can be locked on the lock plate 20. As an embodiment of the present disclosure, Figures 1 to 4As shown, each lock hole 21 is arranged to extend along the radial direction of the rotating shaft 50, and the angles between each two adjacent lock holes 21 are the same. It can be understood that a plurality of lock holes 21 with the same angles can be formed on the lock plate 20 as a structure similar to a dial, and when adjusting the opening and closing degree of the damper 40 of the glass substrate shaping furnace, the plurality of lock holes 21 cooperate with each other to indicate a reference adjustment angle value for the adjustment handle 10, so that the operator can refer to the position of the lock hole 21 and correspondingly rotate the adjustment handle 10, which is conducive to improving the accuracy of adjusting the opening and closing degree of the damper 40.
[0040] Optionally, the lock plate 20 is further provided with a scale, which is provided on the side of the lock hole 21 away from the rotating shaft 50 of the damper 40. In this way, when the airflow and temperature field in the furnace body of the glass substrate shaping furnace need to be adjusted during the production process of the optoelectronic display glass substrate, the operator can hold the grip 11, without using auxiliary measuring tools, and directly rotate the adjustment handle 10 according to the scale on the lock plate 20, so that the adjustment handle 10 is rotated to a suitable position to adjust the opening and closing degree of the damper 40, thereby achieving the adjustment of the airflow and temperature field in the furnace body of the glass substrate shaping furnace, and further improving the adjustment efficiency of the opening and closing degree of the damper 40 of the glass substrate shaping furnace.
[0041] In the air door opening adjustment device of the glass substrate shaping furnace disclosed in the present invention, in order to further prevent the locking member 31 from gluing to the locking hole 21 after the glass substrate shaping furnace is used for a long time, and the locking member 31 is difficult to remove from the locking hole 21, optionally, as Figure 3 and Figure 4 As shown, a groove 3121 is provided on one side of the connecting plate 312 close to the locking plate 20, and the groove 3121 is used for inserting a prying tool. In this way, if after long-term use, the locking member 31 and / or the lock hole 21 are affected by the high temperature of the furnace body, and the locking member 31 and / or the lock hole 21 are glued together, and the locking member 31 is difficult to be removed from the lock hole 21, the operator can insert the prying tool into the groove 3121 on the connecting plate 312, and pry the locking member 31 out of the lock hole 21 by the prying tool, thereby further improving the anti-gluing effect of the air door opening adjustment device of the glass substrate shaping furnace, and also improving the service life of the air door opening adjustment device of the glass substrate shaping furnace.
[0042] For the embodiment in which the connecting plate 312 is provided with a groove 3121 on one side close to the locking plate 20 and the groove 3121 is used for inserting a prying tool, in order to prevent the prying tool from damaging the adjusting handle 10, as shown in FIG. Figures 3 to 5As shown, optionally, the extending direction of the groove 3121 is set at an angle to the extending direction of the portion of the adjusting handle 10 located between the two clamping plates 311. In this way, if the locking member 31 and / or the lock hole 21 are affected by high temperature during long-term use, the locking member 31 and / or the lock hole 21 will be glued together, and when the operator uses a prying tool to pry the locking member 31 out of the lock hole 21, the prying tool will not directly contact the adjusting handle 10, effectively avoiding the prying tool from directly contacting the adjusting handle 10, and the prying tool is prone to damage the adjusting handle 10, thereby increasing the service life of the air door opening adjustment device of the glass substrate shaping furnace.
[0043] In order to further improve the reliability of the adjustment handle 10 being locked on the lock plate 20, optionally, as Figures 3 to 5 As shown, the locking structure 30 also includes a limit pin 32, and the extension direction of the limit pin 32 is set at an angle to the insertion direction of the clamping plate 311 into the lock hole 21. The limit hole 12 is set on the adjustment handle 10, and a first through hole 3111 is formed on any one of the two clamping plates 311. The limit pin 32 is used to pass through the first through hole 3111 and be inserted into the limit hole 12. In this way, after the opening and closing degree of the damper 40 of the glass substrate shaping furnace is adjusted, the operator can first insert the two clamping plates 311 on the locking member 31 into the lock hole 21 on the lock plate 20, and then insert the limit pin 32 through the first through hole 3111 on the clamping plate 311 into the limit hole 12 on the adjustment handle 10. The outer peripheral surface of the limit pin 32 can abut against the inner peripheral surface of the limit hole 12, and the limit pin 32 can limit the movement of the locking member 31 in the direction of disengaging from the lock hole 21. This effectively prevents the locking member 31 from being affected by external forces (such as vibration, operator's accidental touch) and other factors when the locking member 31 locks the adjusting handle 10 on the locking plate 20, causing the locking member 31 to slip out of the locking hole 21, and the locking member 31 cannot lock the adjusting handle 10 on the locking plate 20, resulting in displacement of the adjusting handle 10, causing the damper 40 to rotate, resulting in changes in the air flow and temperature field in the furnace body of the glass substrate shaping furnace, and affecting the normal production of the optoelectronic display glass substrate.
[0044] Alternatively, if Figures 3 to 5As shown, the locking structure 30 also includes a limit bracket 33 and a limit plate 34. The limit bracket 33 includes two side plates 331 and a stop plate 332 connected between the two side plates 331. The two side plates 331 and the stop plate 332 form a U shape. The ends of the two side plates 331 away from the stop plate 332 are connected to a clamping plate 311 formed with a first through hole 3111. The stop plate 332 is formed with a second through hole 3321 for the limit pin 32 to pass through. The limit plate 34 is located in the limit bracket 33 and fixed on the limit pin 32. The stop plate 332 is used to stop the limit plate 34. In this way, when the limit pin 32 passes through the second through hole 3321 and is installed in the limit bracket 33, and the limit plate 34 is fixedly installed on the limit pin 32, the stop plate 332 can limit the limit plate 34 and the limit pin 32, and the limit plate 34 can only move between the stop plate 332 and the card plate 311 formed with a through hole. The limit plate 34 and the limit pin 32 will not fall off from the limit bracket 33, which effectively avoids the limit pin 32 from being lost during use and affecting the normal use of the air door opening adjustment device of the glass substrate shaping furnace.
[0045] The present disclosure does not limit the connection relationship between the limit plate 34 and the limit pin 32, as long as the limit plate 34 can be located in the limit bracket 33 and can be fixedly installed on the limit pin 32. As one embodiment of the present disclosure, the above-mentioned limit plate 34 is welded on the limit pin 32. As other embodiments of the present disclosure, the above-mentioned limit plate 34 can also be clamped on the limit pin 32.
[0046] Here, it should be noted that the present disclosure does not limit the specific shape of the limit pin 32, as long as the limit pin 32 is suitable for inserting into the limit hole 12 on the adjustment handle 10 and can limit the locking member 31. As an embodiment of the present disclosure, optionally, Figures 3 to 5 As shown, the stop pin 32 is formed in a T shape. As another embodiment, the stop pin 32 may also be formed in an L shape.
[0047] In order to facilitate the insertion of the locking member 31 into the lock hole 21, or to remove the locking member 31 from the lock hole 21, optionally, as shown in FIG. Figure 5As shown, the locking structure 30 also includes an operating handle 35, which is connected to the side of the connecting plate 312 away from the clamping plate 311. In this way, when the opening and closing degree of the damper 40 of the glass substrate shaping furnace needs to be adjusted, the operator can remove the locking member 31 from the lock hole 21 by operating the handle 35, thereby adjusting the position of the adjustment handle 10 on the lock plate 20 and adjusting the opening and closing degree of the damper 40 of the glass substrate shaping furnace. In addition, after the opening and closing degree of the damper 40 of the glass substrate shaping furnace is adjusted, the operator can also insert the locking member 31 into the lock hole 21 by operating the handle 35, thereby locking the adjustment handle 10 on the lock plate 20, and the operating handle 35 can improve the efficiency of disassembling and assembling the locking member 31 on the lock hole 21.
[0048] Here, it should be noted that the present disclosure does not limit the specific shape of the operating handle 35, as long as the operating handle 35 is suitable for the operator to hold. As an embodiment of the present disclosure, optionally, Figures 3 to 5 As shown, the operating handle 35 is formed in a T shape. As another embodiment, the operating handle 35 can also be formed in an L shape.
[0049] In the air door opening adjustment device of the glass substrate shaping furnace disclosed in the present invention, since the adjustment handle 10 is connected to the rotating shaft 50 of the air door 40 of the glass substrate shaping furnace, the heat in the furnace body of the glass substrate shaping furnace will be transferred to the adjustment handle 10 through the rotating shaft 50 of the air door 40, resulting in a high temperature of the adjustment handle 10. In order to improve the safety of the above air door opening adjustment device, optionally, a heat insulating member 13 is sleeved on the gripping portion 11. In this way, when the operator grips the gripping portion 11 and rotates the adjustment handle 10, the heat insulating member 13 can isolate the heat on the adjustment handle 10, effectively avoiding the operator from being scalded by the adjustment handle 10 when adjusting the opening and closing degree of the air door 40 of the glass substrate shaping furnace, thereby improving the safety of the air door opening adjustment device of the glass substrate shaping furnace.
[0050] It should be noted that the present disclosure does not limit the material of the air door opening adjustment device of the glass substrate shaping furnace, as long as the air door opening adjustment device of the glass substrate shaping furnace is not easily deformed and glued due to heat. As an embodiment of the present disclosure, the above-mentioned adjustment handle 10, lock plate 20 and locking structure 30 are all made of metal material, and the melting point of the above-mentioned adjustment handle 10, lock plate 20 and locking structure 30 is greater than or equal to 300°C.
[0051] According to a second aspect of the present disclosure, a glass substrate shaping furnace is provided, comprising a furnace body, a damper 40 and the damper opening adjustment device of the glass substrate shaping furnace as described above, the rotating shaft 50 of the damper 40 passes through the furnace body, the adjusting handle 10 of the damper opening adjustment device of the glass substrate shaping furnace is arranged on the outside of the furnace body and connected to the rotating shaft 50 of the damper 40, and the locking plate 20 of the damper opening adjustment device of the glass substrate shaping furnace is arranged on the outside of the furnace body and installed on the furnace body.
[0052] The glass substrate shaping furnace has all the beneficial effects of the air door opening adjustment device of the glass substrate shaping furnace, which will not be described in detail here.
[0053] Here, the present disclosure does not limit the adjustment method of the damper 40 of the glass substrate shaping furnace. As an embodiment of the present disclosure, the number of the dampers 40 can be two, and each damper 40 is correspondingly provided with the damper opening adjustment device. In this way, the operator can control the two damper opening adjustment devices on both sides to adjust the opening and closing of the damper 40. Specifically, the damper opening adjustment device for the shaping furnace provided by the present disclosure can make the damper 40 have the following three states:
[0054] The damper 40 is completely closed, that is, when the optoelectronic display glass substrate production line has not yet started glass substrate production, the furnace body needs to undergo a heating process of about one month so that the shaping furnace can reach a corresponding high temperature state. During this period, the damper 40 must be kept in a closed state to prevent heat loss from the furnace body and cause equipment damage.
[0055] The damper 40 is half-open, that is, the damper 40 maintains a certain opening and closing degree, so that the glass substrate can flow down from the gap between the two dampers 40. The damper opening adjustment device of the glass substrate shaping furnace provided by the present disclosure can fine-tune the opening and closing degree of the damper 40, and after the adjustment is completed, the locking member 31 and the limit pin 32 can lock the adjustment handle 10 on the locking plate 20, thereby ensuring that the opening and closing degree of the damper 40 remains unchanged, so as to meet the process requirements of the glass substrate shaping furnace.
[0056] The air door 40 is fully opened. When the glass substrate shaping furnace is cleaned and maintained, the shaping furnace air door opening adjustment device can be operated to quickly adjust the opening of the two air doors 40 to the maximum, so as to achieve the connection between the upper and lower cavities of the glass substrate shaping furnace, which is convenient for cleaning and maintenance of the glass substrate shaping furnace. The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, the technical solution of the present disclosure can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present disclosure.
