Description

Technical Field

[0001] The present application relates to the technical field of glass processing, and in particular to an annealing roller driving device, a glass annealing furnace and an annealing roller preheating method. Background Art

[0002] During the annealing process of the flat glass in the annealing kiln, the surface of the annealing roller is often not smooth and flat due to the adhesion of a large amount of sulfide, which affects the quality of the lower surface of the glass. Therefore, the annealing roller usually needs to be removed and polished regularly, and then re-installed into the annealing kiln after being polished and smooth. Because the temperature of the annealing roller has dropped significantly during the re-installation process, the annealing roller with insufficient temperature will easily cause the temperature under the plate to change when it contacts the glass, and it is easy to cause the glass to explode vertically. Therefore, the annealing roller needs to be pushed into the annealing kiln and hung for preheating, and then adjusted into place and transmission occurs after the temperature is consistent.

[0003] During the preheating process of the annealing roller, the annealing roller is easily bent and deformed when suspended for a long time without transmission, which makes installation difficult. At the same time, the deformed annealing roller may also cause equipment damage, glass ribbon breaking and other adverse consequences. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings, i.e., embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0048] Annealing rollers usually need to be removed and polished regularly, and then loaded into the annealing kiln again after being polished and smooth. However, since the temperature of the annealing rollers has dropped significantly during the re-loading process, the annealing rollers with insufficient temperature will easily cause temperature changes under the plate when contacting the glass, and may easily cause the glass to explode vertically. Therefore, the annealing rollers need to be pushed into the annealing kiln and hung for preheating, and then adjusted into place and transmission can be generated after the temperature is consistent.

[0049] During the preheating process of the annealing roller, if the annealing roller is suspended for a long time without transmission, it is very easy to cause the annealing roller to bend and deform, which will make installation difficult. At the same time, the deformed annealing roller will also cause equipment damage, glass ribbon breaking and other adverse consequences.

[0050] Therefore, the present application provides an annealing roller driving device, a glass annealing furnace and an annealing roller preheating method, wherein the annealing roller driving device includes a driving assembly and the driving assembly includes a first driving member and a second driving member, the first driving member is used to drive the annealing roller to rotate when the annealing roller is in normal use to achieve the effect of conveying glass, and the second driving member is used to drive the annealing roller to rotate when the annealing roller is suspended in the air, so that the annealing roller can also keep rotating during the preheating process, thereby improving the situation where the annealing roller is bent and deformed due to being left stationary.

[0051] In order to illustrate the technical solution described in this application, the following is a description with reference to specific drawings and embodiments.

[0052] refer to Figures 1 to 3 , Figure 5In a first aspect, an embodiment of the present application provides an annealing roller driving device 100 , comprising an annealing roller 10 , a driving assembly 20 and a transmission assembly 30 .

[0053] The annealing roller 10 is used to convey glass in the annealing furnace; the transmission assembly 30 is arranged on one side of the driving assembly 20, and the transmission assembly 30 can drive the driving assembly 20 to work. The transmission assembly 30 includes a power source, a transmission shaft and a plurality of gears coaxially arranged on the transmission shaft, and may also include a power source, a transmission shaft and a plurality of friction wheels or other transmission structures coaxially arranged on the transmission shaft.

[0054] The annealing roller 10 has a first position and a second position different from the first position, and the first position and the second position are at different heights. The first position is the position of the annealing roller 10 when it works normally. At this time, the annealing roller 10 is in contact with the glass and is used to convey the glass. The second position is the position of the annealing roller 10 when it is suspended for preheating. At this time, the annealing roller 10 is suspended in the air and does not contact the glass, that is, the second position is lower than the first position. The position change of the annealing roller 10 between the first position and the second position can be achieved by a crane, a jack or other equipment.

[0055] The driving assembly 20 is used to drive the annealing roller 10 to rotate. The driving assembly 20 is arranged on one side of the annealing roller 10. The driving assembly 20 can be directly arranged on the annealing kiln, or a frame or base can be separately provided to carry the driving assembly 20; the driving assembly 20 includes a first driving member 21 and a second driving member 22. The first driving member 21 is arranged on one side of the annealing roller 10, and the first driving member 21 can drive the annealing roller 10 to rotate. Specifically, the first driving member 21 can be directly coaxially fixedly connected to the annealing roller 10 so that the annealing roller 10 can rotate synchronously with the first driving member 21. The first driving member 21 can also be connected to the annealing roller 10 through a gear box or other transmission components and drive the annealing roller 10 to rotate. The second driving member 22 is movably connected to the first driving member 21; the first driving member 21 and the second driving member 22 are used to cooperate with the transmission assembly 30. The specific types of the first driving member 21 and the second driving member 22 need to be selected according to the transmission assembly 30, for example, they can be gears, friction wheels or other transmission components.

[0056] The transmission assembly 30 can be connected to the first driving member 21 to drive the annealing roller 10 to rotate in the first position, that is, when the annealing roller 10 is in the first position, the transmission assembly 30 can drive the first driving member 21 to rotate, thereby driving the annealing roller 10 to rotate.

[0057] The transmission assembly 30 can also be transmission-connected to the second driving member 22, and the second driving member 22 is transmission-connected to the first driving member 21, so as to drive the annealing roller 10 to transmit in the second position, that is, when the annealing roller 10 is in the second position, the transmission assembly 30 is spaced apart from the first driving member 21, and the first driving member 21 is disengaged from the transmission connection with the transmission assembly 30, the second driving member 22 is transmission-connected to the first driving member 21 and is transmission-connected to the transmission assembly 30, the transmission assembly 30 drives the second driving member 22 to rotate, and the second driving member 22 rotates to drive the first driving member 21 to rotate, thereby driving the annealing roller 10 to rotate.

[0058] The first driving member 21 is used to be connected to the transmission assembly 30 when the annealing roller 10 is in the first position. At this time, the second driving member 22, the annealing roller 10 and the transmission assembly 30 are all spaced apart to prevent the second driving member 22 from affecting the normal rotation of the annealing roller 10. Here, the spacing of the second driving member 22, the annealing roller 10 and the transmission assembly 30 can refer to the second driving member 22 being connected to the first driving member 21 and being arranged beside the first driving member 21, or the second driving member 22 being separated from the first driving member 21 and being in other positions; the second driving member 22 is used to be connected to the transmission assembly 30 when the annealing roller 10 is in the second position. At this time, the second driving member 22 is also connected to the first driving member 21, and the second driving member 22 can drive the first driving member 21 to rotate, and the first driving member 21, the annealing roller 10 and the transmission assembly 30 are all spaced apart to prevent the first driving member 21 from affecting the normal rotation of the annealing roller 10.

[0059] The movable connection mode between the second driving member 22 and the first driving member 21 can be a sliding connection, a detachable connection or other connection modes; in some embodiments, the movable connection mode between the second driving member 22 and the first driving member 21 is a detachable connection. Specifically, when the annealing roller 10 is in the first position, the second driving member 22 is removed from the first driving member 21, and when the annealing roller 10 is in the second position, the second driving member 22 is installed on the first driving member 21; in other embodiments, the movable connection mode between the second driving member 22 and the first driving member 21 is based on The sliding connection is based on a spline. Specifically, the spline is arranged along the axial direction of the first driving member 21, and the second driving member 22 can slide along the axial direction of the spline. When the annealing roller 10 is in the first position, the second driving member 22 slides in a direction away from the first driving member 21 to avoid interfering with the rotation of the transmission assembly 30 and the annealing roller 10. When the annealing roller 10 is in the second position, the second driving member 22 moves in a direction close to the first driving member 21 and is connected to the transmission assembly 30 to drive the first driving member 21 to rotate through the spline, thereby driving the annealing roller 10 to rotate.

[0060] It can be understood that since there are usually multiple annealing rollers 10, there are also multiple drive assemblies 20, and each drive assembly 20 corresponds to one annealing roller 10, and the transmission assembly 30 is used to drive the first drive member 21 or the second drive member 22 to rotate, so there can be only one transmission assembly 30 or there can be multiple transmission assemblies 30.

[0061] In this embodiment, when the annealing roller 10 is in the second position, the annealing roller 10 is in a suspended preheating state, and the annealing roller 10 is not in contact with the glass. At this time, the second driving member 22 can drive the annealing roller 10 to rotate through the transmission assembly 30, thereby improving the situation in which the annealing roller 10 is bent and deformed due to gravity during the suspended preheating process.

[0062] In this embodiment, the first driving member 21 is used to provide power to the annealing roller 10 during the normal glass conveying process. When the annealing roller 10 is in the second position, the user can ensure the rotation of the annealing roller 10 when the annealing roller 10 is suspended in the air only by moving the second driving member 22, without the need to additionally set up a complex driving system such as a motor. The operation is simple, the space occupancy is small, and the cost is also lower. Compared with the manual rotation of the annealing roller 10, this setting improves safety and enables the staff to perform other work during the preheating of the annealing roller 10, saving labor.

[0063] In some embodiments, the second driving member 22 is made of plastic, for example, the second driving member 22 can be made of nylon material. Setting the second driving member 22 to be a plastic material can reduce the weight of the second driving member 22, so as to facilitate installation and disassembly by staff. At the same time, the nylon material also has excellent mechanical strength, good wear resistance and corrosion resistance, and can meet the needs of the second driving member 22 during the production and processing process.

[0064] refer to Figure 1 In one embodiment, the transmission assembly 30 includes a power source 31 and a transmission member 32 .

[0065] The power source 31 is used to provide power for the transmission member 32 , and the power source 31 may be a motor or other rotary power source 31 ; the power source 31 may be directly arranged on the annealing furnace, or a separate bracket may be provided to support and fix the power source 31 .

[0066] The transmission member 32 can be a gear, a friction wheel or other transmission components. The number of the transmission members 32 is the same as the number of the drive components 20, so that each transmission member 32 can drive the corresponding first drive member 21 or the second drive member 22 to rotate; the transmission member 32 is connected to the first drive member 21 to drive the first drive member 21 to rotate, and the transmission member 32 can also drive the first drive member 21 to rotate through the second drive member 22 when the annealing roller 10 is in the second position. The specific way for the power source 31 to drive the first drive member 21 to rotate is to connect the second drive member 22 to the first drive member 21. The connection method can be a fixed connection, or it can be a slidable connection through a spline or other transmission connection methods.

[0067] In some embodiments, the first driving member 21, the second driving member 22 and the transmission member 32 are all gears. This setting can ensure the stability of the transmission between the first driving member 21 and the transmission member 32, and the second driving member 22 and the transmission member 32. The specific parameters and types of the first driving member 21, the second driving member 22 and the transmission member 32 can be selected according to actual production needs, for example, refer to Figure 1 The axial direction of the first driving member 21 is perpendicular to the axial direction of the transmission member 32. At this time, the first driving member 21, the second driving member 22 and the transmission member 32 can be helical gears or bevel gears.

[0068] In some embodiments, the transmission assembly 30 further includes a transmission shaft 33, the power source 31 is connected to the transmission shaft 33 and can drive the transmission shaft 33 to rotate, and the transmission member 32 is connected to the transmission shaft 33 so that the rotation of the transmission shaft 33 can drive the transmission member 32 to rotate.

[0069] In some embodiments, the radial height of the second driving member 22 is greater than that of the first driving member 21, and the radial height refers to the dimension in the height direction. For example, when the first driving member 21 and the second driving member 22 are both gears, the pitch circle diameter of the second driving member 22 is greater than the pitch circle diameter of the first driving member 21; because the heights of the first position and the second position are different, and the second position is lower than the first position, this arrangement enables the second driving member 22 to be connected to the transmission assembly 30 when the annealing roller 10 is in the second position, and can also ensure that the first driving member 21 is spaced apart from the first driving member 21 when the annealing roller 10 is in the second position.

[0070] In some embodiments, the second driving member 22 can be fixed to the first driving member 21 when the annealing roller 10 is in the second position. At this time, the second driving member 22 can drive the first driving member 21 to rotate, so as to achieve the effect that the power source 31 drives the first driving member 21 to rotate; in other embodiments, the second driving member 22 is connected to the first driving member 21 in transmission, for example, the second driving member 22 is connected to the first driving member 21 through a spline, and the spline is arranged along the axial direction of the first driving member 21, so that the second driving member 22 can slide along the axial direction of the first driving member 21, and at the same time, the rotation of the second driving member 22 can drive the first driving member 21 to rotate synchronously through the spline, so as to achieve the effect that the power source 31 drives the first driving member 21 to rotate.

[0071] refer to Figures 4 to 6 In one embodiment, a receiving groove 221 is provided on the second driving member 22. The receiving groove 221 is specifically provided on the side of the second driving member 22 facing the first driving member 21. The receiving groove 221 is used to receive the first driving member 21. That is, when the annealing roller 10 is in the second position, the first driving member 21 can be received in the receiving groove 221 to facilitate the transmission connection between the second driving member 22 and the transmission assembly 30.

[0072] Furthermore, when the first driving member 21 is accommodated in the accommodating groove 221, the first driving member 21 can be fixedly connected to the second driving member 22 and move synchronously; or, the first driving member 21 is transmission-connected to the second driving member 22, for example, the outer surface of the first driving member 21 and the inner wall of the accommodating groove 221 are provided with matching splines.

[0073] When the annealing roller 10 is in the second position, the arrangement of the accommodating groove 221 enables the first driving member 21 to be accommodated in the accommodating groove 221 to avoid affecting the rotation of the transmission member 32 and ensure the stability of the transmission.

[0074] refer to Figures 4 to 6 In one embodiment, the second driving member 22 is detachably connected to the first driving member 21, and the second driving member 22 can be fixed to the first driving member 21 when the annealing roller 10 is in the second position. Specifically, the driving assembly 20 also includes a bolt 24 and a locking nut 25, and the bolt 24 and the locking nut 25 are used to fix the second driving member 22 to the first driving member 21 when the annealing roller 10 is in the second position.

[0075] A first through hole 211 is provided on the first driving member 21, and a second through hole 222 is provided on the second driving member 22. The second through hole 222 is specifically provided on the bottom wall of the accommodating groove 221 away from the first driving member 21. When the annealing roller 10 is in the second position, the first driving member 21 is accommodated in the accommodating groove 221, and the first through hole 211 and the second through hole 222 are coaxially arranged. One end of the bolt 24 can be threadedly connected with the locking nut 25 after passing through the first through hole 211 and the second through hole 222. When the locking nut 25 is threadedly connected with the bolt 24, the locking nut 25 moves in a direction close to the second driving member 22 and finally abuts against the second driving member 22, so that the first driving member 21 is stably fixed in the accommodating groove 221 by the bolt 24.

[0076] In some embodiments, the drive assembly 20 further includes a sleeve 26 , which can be sleeved on the bolt 24 , and the sleeve 26 can be a sleeve 26 with internal threads.

[0077] The inner diameter of the first through hole 211 is greater than the inner diameter of the second through hole 222. When the bolt 24 passes through the first through hole 211, the sleeve 26 is accommodated in the first through hole 211, and the outer wall of the sleeve 26 abuts against the inner wall of the first through hole 211. The sleeve 26 is used to limit the axial rotation of the first driving member 21 relative to the second driving member 22, and cooperates with the bolt 24 to press the first driving member 21 against the bottom wall of the accommodating groove 221, thereby further ensuring that the first driving member 21 is stably fixedly connected to the second driving member 22 when the annealing roller 10 is in the second position.

[0078] This embodiment provides a specific method for realizing detachable connection between the first driving member 21 and the second driving member 22. It can be understood that the first driving member 21 and the second driving member 22 can also be detachably connected by other methods, for example, by snapping them together.

[0079] refer to Figure 5 , Figure 6In some embodiments, the drive assembly 20 further includes a stop ring 27, which is disposed on a side of the bolt 24 away from the locking nut 25, that is, the stop ring 27 is disposed on a side of the first drive member 21 away from the second drive member 22. When the second drive member 22 is fixedly connected to the first drive member 21, one end of the bolt 24 passes through the stop ring 27, the first drive member 21, and the second drive member 22 in sequence and is threadedly connected to the locking nut 25. Specifically, a through hole for the bolt 24 to pass through is provided on the stop ring 27. As the locking nut 25 gradually approaches the second drive member 22, the bolt 24 presses the stop ring 27 against the first drive member 21 and the pressure becomes greater and greater. At the same time, the pressure between the first drive member 21 and the second drive member 22 can also be increased to increase the friction between the stop ring 27 and the first drive member 21, and between the first drive member 21 and the second drive member 22, so that the second drive member 22 can be stably fixedly connected to the first drive member 21.

[0080] The setting of the stop ring 27 enables the bolt 24 to better press the first driving member 21 onto the second driving member 22. At the same time, the stop ring 27 can also reduce the pressure between the screw head of the bolt 24 and the first driving member 21 to prevent crushing and permanent plastic deformation, thereby ensuring the effectiveness of the bolt 24 connection.

[0081] Furthermore, the stop ring 27 includes two half rings 271 , and the two half rings 271 can be assembled and combined to form a complete stop ring 27 . The stop ring 27 is configured as two half rings 271 to facilitate the installation of the stop ring 27 .

[0082] The action process of the annealing roller driving device 100 provided in the first aspect of the embodiment of the present application is as follows: when the annealing roller 10 is in the first position, the first driving member 21 is in transmission cooperation with the transmission member 32, and the rotation of the transmission member 32 can drive the annealing roller 10 to rotate through the first driving member 21 to convey the glass, and at this time the second driving member 22 is separated from the first driving member 21; when the annealing roller 10 is removed and the cleaning and polishing are completed, the annealing roller 10 is placed in the second position for preheating, and at this time the second driving member 22 is installed on the first driving member 21, specifically, the first driving member 21 is accommodated in the receiving groove 221 and abuts against the bottom wall of the receiving groove 221, and then the stopper is The ring 27 is installed on the side of the first driving member 21 away from the second driving member 22, so that one end of the bolt 24 passes through the retaining ring 27, the first driving member 21 and the second driving member 22 in sequence and then engages with the locking nut 25 threadedly, and the locking nut 25 is screwed and finally abuts against the side of the second driving member 22 away from the first driving member 21 to complete the fixation of the second driving member 22. At this time, the second driving member 22 is connected to the transmission member 32 in transmission connection, and the annealing roller 10 is driven to rotate through the first driving member 21, so that the annealing roller 10 can keep rotating during the suspended preheating process, so as to improve the bending deformation of the annealing roller 10 caused by standing still.

[0083] The second aspect of the present application provides a glass annealing furnace, which includes the annealing roller drive device 100 provided in the first aspect of the embodiment. The glass annealing furnace includes the beneficial effects of the annealing roller drive device 100 provided in the first aspect of the embodiment. At the same time, under the action of the annealing roller drive device 100, it can ensure the stable transmission of glass during the daily use of the glass annealing furnace. At the same time, it can also ensure that the annealing roller 10 can rotate automatically when the annealing roller 10 is suspended for preheating, without manual rotation, thereby improving safety performance while saving manpower and reducing costs.

[0084] The glass annealing furnace also includes a bracket, and the transmission assembly 30, the drive assembly 20 and the annealing roller 10 are all installed on the bracket. The annealing roller 10 has at least two heights on the bracket so that the annealing roller 10 is respectively in a first position and a second position. The annealing roller 10 can specifically achieve the change between the first position and the second position through external equipment such as a gantry crane and a jack or the structure of the glass annealing furnace itself.

[0085] refer to Figure 7 The third aspect of the present application provides an annealing roller preheating method, which is applied to the annealing roller driving device 100 provided in the first aspect of the present application, or the glass annealing furnace provided in the second aspect of the present application; the annealing roller preheating method specifically includes:

[0086] S201: Install the annealing roller 10 to the second position.

[0087] In this step, the second position is the preheating position of the annealing roller 10 , in which the annealing roller 10 can be gradually heated without contacting the glass.

[0088] S202 : Connect the second driving member 22 to the first driving member 21 , and connect the second driving member 22 to the transmission assembly 30 in transmission connection.

[0089] In this step, the second driving member 22 is connected to the first driving member 21 so that the second driving member 22 can drive the first driving member 21 to rotate; the specific action of connecting the second driving member 22 to the first driving member 21 can be to install the second driving member 22 on the first driving member 21 through the bolt 24 and the locking nut 25, and the second driving member 22 can also be set to slide axially relative to the first driving member 21 through a spline, so that the second driving member 22 can be connected to the transmission assembly 30 when the annealing roller 10 is in the second position, and the second driving member 22 can also be set at a distance from the annealing roller 10 when the annealing roller is in the first position.

[0090] S203 : driving the first driving member 21 and the annealing roller 10 to rotate through the second driving member 22 , and preheating the annealing roller 10 .

[0091] In this step, the second driving member 22 is driven and connected to the transmission assembly 30, so that the second driving member 22 can drive the first driving member 21 and the annealing roller 10 to rotate. The rotation of the annealing roller 10 can prevent one side of the annealing roller 10 from being subjected to its own gravity for a long time and causing bending deformation, so as to improve the situation where the annealing roller 10 is suspended and caused to bend and deform.

[0092] In this step, the temperature of the annealing roller 10 gradually increases. Depending on the required temperature of the annealing roller 10, the time required for this step can be 3 to 5 minutes, or 10 to 50 minutes or other time. In this process, the second driving member 22 always drives the annealing roller 10 to rotate, and the staff does not need to stand by all the time and can engage in other work, thereby achieving the effect of saving manpower.

[0093] S204 : Disconnect the second driving member 22 from the transmission assembly 30 .

[0094] In this step, after the temperature of the annealing roller 10 reaches the required temperature, the second driving member 22 is disengaged from the transmission assembly 30. The disengagement can be directly removed from the first driving member 21 or moved to one side of the first driving member 21. It can be understood that the position of the second driving member 22 will not affect the transmission connection between the first driving member 21 and the transmission assembly 30 when the annealing roller 10 is in the first position.

[0095] S205 : moving the annealing roller 10 from the second position to the first position, and connecting the first driving member 21 to the transmission assembly 30 .

[0096] In this step, the first position is the working position of the annealing roller 10. In the second position, the annealing roller 10 can convey the glass. At this time, the first driving member 21 is connected to the transmission assembly 30, and the first driving member 21 can drive the annealing roller 10 to rotate to meet the demand for conveying glass during the glass annealing process.
