The terms "first," "second," and the like as used herein are intended to distinguish one element from another, and are not necessarily sequential or significant. Furthermore, in the following description, when referring to the figures, the same reference numbers in different figures denote the same or similar elements, unless otherwise explained. The foregoing definitions are provided only to explain and illustrate the present disclosure and should not be construed as limiting the present disclosure

According to an embodiment of the present disclosure, an annealing furnace is provided, one embodiment of which is shown in fig. 1. Referring to fig. 1, the lehr includes a furnace body 50 disposed in suspension, a pair of pulling rolls 10 extending in a transverse direction perpendicular to a conveyance direction of the substrate glass, and actuating devices 20 for driving the pulling rolls 10 to rotate, the actuating devices 20 being disposed in one-to-one correspondence with the pulling rolls 10, the furnace body 50 having a first side 501 and a second side 502 opposite to each other in the transverse direction, characterized in that the actuating device 20 for driving one pulling roll 10 of the pair of pulling rolls 10 is disposed on the first side 501, and the actuating device 20 for driving the other pulling roll 10 of the pair of pulling rolls 10 is disposed on the second side 502.

Through the technical scheme, namely the annealing furnace provided by the present disclosure, referring to fig. 1, the actuating devices 20 for driving the paired pulling rolls 10 are respectively arranged on the first side 501 and the second side 502 of the annealing furnace, so that the actuating devices 20 arranged on the two opposite sides of the annealing furnace can provide relatively balanced forces to the two sides of the annealing furnace, so that the two sides of the annealing furnace are relatively level in stress during the operation process, and the operation stability of the annealing furnace is improved. Meanwhile, the actuator 20 is distributed on both sides of the annealing furnace, so that a large installation space can be given to the actuator 20, and the selection of the actuator 20 is not limited by the installation space.

In the embodiment provided in the present disclosure, referring to fig. 1 to 3, in order to connect the actuator 20 with the pulling roll 10 on the suspended furnace body 50, and simultaneously prevent the actuator 20 from operating in a suspended state under the influence of its own weight, which is large, and thus, the operation is not smooth or not able to operate, and thus, the operation of the furnace body 50 is further affected, therefore, the actuator 20 is mounted on the furnace body 50 through the mounting bracket 30, and the mounting bracket 30 is used for supporting the actuator 20.

As shown in fig. 1 and 2, the actuator 20 includes a motor 201, a reducer 202, and a plurality of flexible couplings 203 connecting the reducer 202 and the traction roller 10, wherein the flexible couplings 203 are capable of buffering a force transmitted from an output shaft of the reducer 202 to the traction roller 10 while connecting the reducer 202 and the traction roller 10, so as to reduce a jumping amount of the traction roller 10 during operation. Alternatively, the flexible coupling 203 may be a flexible coupling without an elastic member, such as a universal coupling or a slider coupling.

Specifically, in the specific embodiment provided by the present disclosure, a universal joint cross is used to buffer the force transmitted from the output shaft of the speed reducer 202 to the traction roller 10 from multiple directions, so as to reduce the jumping amount of the traction roller 10 during operation, and at the same time, facilitate the assembly and disassembly of the coupling inside the supporting frame 301.

Further, referring to fig. 3, the mounting bracket 30 includes a support bracket 301 and a fixing plate 302. Since the motor 201 and the reducer 202 are generally bulky and, accordingly, heavy, during the installation of the entire actuator 20, one of the flexible couplings 203 is connected to the traction roller 10, and then the other of the flexible couplings 203 is connected to the output shaft of the reducer 202, and thereafter, the two flexible couplings 203 having a single free end are connected to each other, thereby completing the installation of the actuator 20. Here, the speed reducer 202 is connected to the fixed plate 302 and the flexible coupling 203 is located in the support bracket 301, and in order to facilitate mounting and dismounting between the flexible coupling 203 and the speed reducer 202, a hinge structure is adopted between the fixed plate 302 and the support bracket 301, and a hinge shaft of the fixed plate 302 defines a horizontal rotation axis so that the support bracket 301 can rotate relative to the fixed plate 302 around the rotation axis. When the device is installed, the support 301 is rotated by a certain angle along the hinge shaft, one of the flexible couplings 203 is connected to the output shaft of the speed reducer 202, the support 301 is rotated to be attached to the fixing plate 302, and then the fixing plate 302 and the support 301 are fixedly connected. To accomplish this mounting process, the support bracket 301 is removably secured to the furnace body 50.

Based on the above structure, as an example, the support bracket 301 is constructed as a box-shaped structure welded by channel steel in consideration of the mechanical properties required for the support bracket 301 to support the weight of the motor 201 and the speed reducer 202. As such, those skilled in the art will appreciate that the box-type structure may be constructed as a truss structure, as shown with reference to fig. 4. Thus, not only can the weight of the support frame 301 be reduced on the basis of the box-type structure, but also the plurality of flexible couplings 203 located in the middle portion can be removed without removing the entire support frame 301 when replacing the flexible couplings 203, and the support strength required for supporting the motor 201 and the speed reducer 202 is satisfied, and the weight is reduced.

In the specific embodiment provided by the present disclosure, referring to fig. 3, in order to realize the connection between the speed reducer 202 and the fixing plate 302, a flange may be fixedly disposed on the speed reducer 202, and a mounting hole that is fittingly connected with the flange and a through hole for extending an output shaft of the speed reducer 202 are disposed on the fixing plate 302. Thus, fasteners are used to pass through the flange plate and the mounting holes of the stationary plate 302 to complete the mounting of the reducer 202 on the stationary plate.

In the specific embodiment provided by the present disclosure, referring to fig. 1, the annealing furnace includes a plurality of counterweight swing arms 40, and the plurality of counterweight swing arms 40 are arranged in a central array around the furnace body 50 at the same height position. Specifically, at least two pairs of counterweight rocker arms 40 are included, each pair of counterweight rocker arms 40 are respectively distributed on the first side 501 and the second side 502 of the furnace body 50 and are oppositely arranged along the connecting line direction between the paired pulling rolls 10, so as to simultaneously apply opposite forces to the paired pulling rolls 10, that is, form a clamping force, so that the paired pulling rolls 10 move towards the center of the furnace body 50, further, can clamp the substrate glass and convey the substrate glass to the inside of the furnace body 50.

In the embodiment provided by the present disclosure, based on the above-described structure, as shown with reference to fig. 1, two actuators 20 for driving the pair of pulling rolls 10 are arranged in a central array around the furnace body 50 at the same height. In this way, the two actuating devices 20 with the same structure and located at the same height of the furnace body 50 apply the same force, and the two actuating devices 20 are respectively arranged at the two sides of the furnace body 50, so that the stress at the two sides of the furnace body 50 can be kept balanced relatively, thereby ensuring the running stability of the furnace body 50.

In the embodiment provided by the present disclosure, the actuating device 20 and the furnace body 50 have the following installation processes:

firstly, the motor 201 and the speed reducer 202 are fixedly connected and then installed on the fixed plate, then the fixed plate 302 and the support frame 301 are connected by using a hinge structure, when the installation is carried out, the support frame 301 is rotated along a hinge shaft for a certain angle, one of the flexible couplings 203 is connected to an output shaft of the speed reducer 202, then the other of the flexible couplings 203 is connected to the traction roller 10, then the two flexible couplings 203 with single free ends are connected with each other and the support frame 301 is rotated to be attached to the fixed plate 302, then the other end of the support frame 301 is fixed on the furnace body 50, and then the installation of the actuating device 20 is completed.

Here, the fixing plate 302 and the supporting frame 301, and the flexible coupling 203, the reduction gear 202, and the traction roller 10 can be mounted independently of each other, and can be operated according to actual conditions.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
