[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] like Figures 1 to 6 As shown, the traction roller replacement device disclosed in the first embodiment of the present application includes: a first force-applying component 10 and a second force-applying component 20, the first force-applying component 10 includes a first frame structure 11, a first mounting seat structure 12 and a first fixed structure 13, the first mounting seat structure 12 is movably connected to the first frame structure 11, the first fixed structure 13 is connected to the first mounting seat structure 12, the first end of the traction roller is detachably connected to the first end of the first fixed structure 13, the second force-applying component 20 is arranged opposite to the first force-applying component 10, the second force-applying component 20 includes a second frame structure 21, a second mounting seat structure 22 and a second fixed structure 23, the second mounting seat structure 22 is movably connected to the second frame structure 21, the second fixed structure 23 is connected to the second mounting seat structure 22, and the second end of the traction roller is detachably connected to the second fixed structure 23.

[0035] By applying the technical solution of the first embodiment, when the traction roller needs to be replaced, the first end and the second end of the traction roller are fixed respectively by the first fixing structure 13 and the second fixing structure 23, the first mounting seat structure 12 moves toward the direction close to the annealing furnace, and the second mounting seat structure 22 moves away from the annealing furnace. After the first fixing structure 13 enters from one side of the annealing furnace and exits from the other side, the traction roller completely exits the annealing furnace, the old traction roller is removed and a new traction roller is installed; the second mounting seat structure 22 moves toward the annealing furnace, the first mounting seat structure 12 and the second mounting seat structure 22 move in the same direction and at the same speed, the new traction roller is put back into the annealing furnace, and the replacement of the traction roller is completed. The technical solution of the first embodiment effectively solves the problem of difficult and dangerous operation in the prior art during the replacement of the annealing furnace traction roller.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in the technical solution of the first embodiment, the first mounting seat structure 12 also includes a first connecting portion 121, a first vertical driving portion 122 and a first mounting seat 123. The first connecting portion 121 is movably connected to the first frame structure 11, the first vertical driving portion 122 is connected to the first connecting portion 121, the first mounting seat 123 is connected to the output end of the first vertical driving portion 122, and the first fixed structure 13 is connected to the first mounting seat 123. A plurality of first horizontal slide rails are arranged on the first frame structure 11, the first connecting portion 121 has a first horizontal slider arranged one-to-one with the first horizontal slide rail, the first horizontal slider is movably connected to the first horizontal slide rail, and the arrangement of the first horizontal slide rail and the first horizontal slider makes the movement of the first connecting portion 121 smoother. The cross-sectional size of the first horizontal slider is continuously reduced in the direction from approaching to moving away from the first horizontal slide rail, so that when the first horizontal slider is clamped in the first horizontal slide rail, the two are not easy to be separated, thereby improving the stability of the entire device. The first vertical driving part 122 drives the first mounting seat 123 to move in the vertical direction, so as to control the height of the traction roller in the vertical direction and avoid the collision between the traction roller and the mounting opening during the movement of the traction roller. The first connecting part 121 is provided with a first vertical slide rail, and the first mounting seat 123 is provided with a first slider corresponding to the first vertical slide rail. The first slider is movably connected to the first vertical slide rail, so that the first mounting seat 123 moves smoothly in the vertical direction and reduces vibration.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in the technical solution of the first embodiment, the first fixing structure 13 includes a first pipe section 131 and a first bolt 132. The first pipe section 131 has a first threaded hole matched with the first bolt 132, and the first bolt 132 is inserted into the first threaded hole. The first bolt 132 is loosened to insert the traction roller to be fixed into the first pipe section 131, and the first bolt 132 is tightened. The end surface of the first bolt 132 abuts against the side of the traction roller to fix the traction roller. In addition, a pin hole can be opened on the traction roller to fix it using a positioning pin.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in the technical solution of the first embodiment, the first mounting seat structure 12 includes a plurality of first mounting seat structures 12, and the plurality of first mounting seat structures 12 are connected to the first fixed structure 13. The arrangement of the plurality of first mounting seats 123 ensures that the force on the first fixed structure 13 is relatively uniform, avoids bending caused by unbalanced force on the first fixed structure 13, and improves the bearing capacity of the entire first force-applying assembly 10.

[0039] like Figure 1, Figure 2 , Figure 3 and Figure 5 As shown, in the technical solution of the first embodiment, the distance between the first mounting seat structure 12 close to the traction roller and the first end of the first fixed structure 13 is greater than the width of the annealing furnace. It is ensured that when the first mounting seat structure 12 moves to the position closest to the annealing furnace that it can reach, the first end of the first fixed structure 13 completely passes through the annealing furnace, ensuring that the traction roller is completely separated from the annealing furnace, which is convenient for the staff to replace the traction roller.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in the technical solution of the first embodiment, the second mounting seat structure 22 also includes a second connecting portion 221, a second vertical driving portion 222 and a second mounting seat 223. The second connecting portion 221 is movably connected to the second frame structure 21, the second vertical driving portion 222 is connected to the second connecting portion 221, the second mounting seat 223 is connected to the output end of the second vertical driving portion 222, and the second fixed structure 23 is connected to the second mounting seat 223. A plurality of second horizontal slide rails are arranged on the second frame structure 21, the second connecting portion 221 has a second horizontal slider arranged one-to-one with the second horizontal slide rail, the second horizontal slider is movably connected to the second horizontal slide rail, and the arrangement of the second horizontal slide rail and the second horizontal slider makes the movement of the second connecting portion 221 smoother. The cross-sectional size of the second horizontal slider is continuously reduced in the direction from approaching to moving away from the second horizontal slide rail, so that when the second horizontal slider is clamped in the second horizontal slide rail, the two are not easy to be separated, thereby improving the stability of the entire device. The second vertical driving part 222 drives the second mounting seat 223 to move in the vertical direction, so as to control the height of the traction roller in the vertical direction and avoid the collision between the traction roller and the mounting opening during the movement of the traction roller. The second connecting part 221 is provided with a second vertical slide rail, and the second mounting seat 223 is provided with a second slider corresponding to the second vertical slide rail. The second slider is movably connected to the second vertical slide rail, so that the second mounting seat 223 moves smoothly in the vertical direction and reduces vibration.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, in the technical solution of the first embodiment, the second fixing structure 23 includes a second pipe section 231 and a second bolt 232. The second pipe section 231 has a second threaded hole matched with the second bolt 232, and the second bolt 232 is inserted into the second threaded hole. The second bolt 232 is loosened to insert the traction roller to be fixed into the second pipe section 231, and the second bolt 232 is tightened. The end surface of the second bolt 232 abuts against the side of the traction roller to fix the traction roller. Similarly, the second fixing structure 23 can also be fixed with a fixing pin.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in the technical solution of the first embodiment, the second force-applying assembly 20 further includes a positioning structure 24, which is connected to the second frame structure 21, and the positioning structure 24 is arranged corresponding to the second fixed structure 23. The positioning structure 24 supports and positions the traction roller, avoids the downward bending and position deviation of the middle part caused by the excessive length of the traction roller, and reduces the force on the first fixed structure 13 and the second fixed structure 23.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in the technical solution of the first embodiment, the positioning structure 24 includes a positioning portion 241, and the height of the positioning portion 241 is continuously reduced from both ends to the middle. The structure of the positioning portion 241 enables the traction roller to be located in the middle of the positioning portion 241 under the action of gravity, thereby reducing the shaking of the traction roller and limiting the radial movement of the traction roller.

[0044] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the positioning structure 24 includes a third mounting seat and a roller, the third mounting seat is connected to the second frame structure 21, the roller is rotatably connected to the third mounting seat, and the roller is arranged one-to-one with the first connecting portion 121. The diameter of the roller is continuously reduced from both ends to the middle and the transition is smooth. The above structure makes the friction force on the traction roller to be rotational friction when the traction roller is moved, and the friction force is reduced, which reduces the friction damage on the surface of the traction roller, improves the service life, and plays the role of positioning the traction roller.

[0045] According to another aspect of the present application, a glass annealing furnace is provided. The glass annealing furnace adopts the above-mentioned traction roller replacement device. The glass annealing furnace is provided with installation ports on both sides of the glass annealing furnace. The first force-applying assembly 10 and the second force-applying assembly 20 are respectively arranged on both sides of the annealing furnace and are arranged corresponding to the installation ports. The first force-applying assembly 10 and the second force-applying assembly 20 are respectively arranged on both sides of the annealing furnace, that is, they are respectively arranged corresponding to the two ends of the traction roller, so that during the process of replacing the traction roller, the two ends of the traction roller are respectively subjected to the force from the first fixed structure 13 and the second fixed structure 23, and the two ends of the traction roller are subjected to uniform force, which makes it easy for the traction roller to maintain balance, reduces the difficulty of operation during the replacement process, and avoids the collision of the traction roller due to unilateral force and unstable movement.

[0046] From the above, it can be known that the present application mainly includes: a main support (a first frame structure 11 and a second frame structure 21), a slide rail assembly (a first horizontal slide rail and a second horizontal slide rail), a control cabinet, a movable support (a first connecting part 121 and a second connecting part 221), a slide rail assembly (a first vertical slide rail and a second vertical slide rail), a base plate (a first mounting seat 123 and a second mounting seat 223), a locking sleeve (a first fixed structure 13 and a second fixed structure 23), a support (a positioning structure 24), a limit locking device (a first limit structure and a second limit structure), a power device (a first horizontal drive structure, a second horizontal drive structure, a first vertical drive part 122 and a second vertical drive part 222), the traction roller is not the content of the present application, and the annealing furnace is not the content of the present application. In the present application, a control cabinet and four slide rail assemblies are installed on the main support, the mobile support is fixed on the four sliders of the slide rail assembly, two sets of slide rail assemblies are vertically installed on the mobile support, the base plate is installed on the four sliders of the slide rail assembly, the locking sleeve and the support are respectively fixed on the base plate, the limit locking device is installed on the main support, the power source is fixed on the mobile support, and the traction roller is installed on the annealing furnace. The mobile support makes a linear reciprocating motion on the main support through the four slide rail assemblies. The limit locking device is set at both ends of the effective working stroke to prevent the mobile support from colliding with the main support and to lock the mobile support in an appropriate position. The guide rails of the power equipment and the slide rail assembly are vertically fixed on the mobile support, the base plate is fixed on the slider of the slide rail assembly, the base plate is powered by the power equipment, and can make a vertical linear motion along the slide rail assembly. The locking sleeve is fixed on the base plate, and the two ends of the traction roller are respectively assembled on the locking sleeve (the first fixed structure 13 and the second fixed structure 23). After the traction roller is assembled on the locking sleeve, the power source pushes the substrate upward, driving the traction roller to lift a certain height, and gives a thrust to the mobile bracket in the first direction to push the traction roller out of the annealing furnace. When the traction roller moves to the main bracket, the power source is used to push the substrate upward through the controller, so that the support member supports the other end of the traction roller. At this time, the waste traction roller can be removed and replaced with a new traction roller, and then a thrust is given to the mobile bracket in the opposite direction to move the traction roller into the annealing furnace to complete the operation of rapid roller replacement.
