[0032] One end of the cable 13 is connected to the output end of the driving assembly 11, and the other end of the cable 13 extends downward and is connected to the mounting frame 15.

[0033] Figure 1 、 Figure 2 and Figure 4 is a structural schematic view of one embodiment of the outer sealing plate lifting device 1 for the glass toughening furnace. Figure 3 The outer sealing plate lifting device 1' in the prior art is shown.

[0034] From Figure 3 It can be seen that the lifting device 1' in the prior art includes a driving assembly 11' mounted on the top of the rack 2, a plurality of mounting frames 15 provided with outer sealing plates, a plurality of guide shafts 13' arranged in front of and behind each other and on the left and right sides of the rack 2, a plurality of annular sliding blocks 16' sleeved on the guide shafts 13', and a transmission chain 12'; the plurality of mounting frames 15 are arranged on the left and right sides of the rack 2, and the front and rear sides of the mounting frame 15 are respectively slidably mounted on the two guide shafts 13' through the four annular sliding blocks 16', so that the outer sealing plate lifting device 1' can drive the mounting frame 15 to move up and down along the guide shaft 13' through the transmission chain 12', so as to raise or lower the mounting frame 15, so that the outer sealing plate is at a corresponding height on the left side or the right side of the rack 2, and the left side or the right side of the rack 2 covered by the outer sealing plate is opened or closed, so as to perform maintenance operation.

[0035] In order to ensure the smoothness of the mounting frame 15 moving up and down along the guide shaft 13', the middle part of the guide shaft 13' cannot have a bending part.

[0036] As Figure 3As shown, if the glass toughening furnace is provided with a component 4 protruding from the left side or right side of the rack 2, and needs to be covered by the outer sealing plate, the guide shaft 13' part close to the component 4 needs to be outwardly protruding, and the guide shaft 13' part close to the component 4 needs to be outwardly protruding from the component 4. The guide shaft 13' thus arranged is far away from the outer surface of the rack 2, and is in a downward inclined or vertical state, resulting in a large space occupied by the lifting device 1'.

[0037] As shown in Figure 1 , Figure 2 and Figure 4 , the outer sealing plate lifting device 1 of the utility model adopts a guide rail 14 with a bending position 143, a guide groove 141 is formed in the guide rail 14, a pulley 12 is arranged in the guide groove 141, and a mounting frame 15 is driven to move up and down along the guide groove 141 by a driving assembly 11 through a cable 13. The guide groove 141 can be bent according to the arrangement of the component 4 on the outer side of the glass toughening furnace, so that the guide groove 141 is close to the outer side of the glass toughening furnace, and the space occupied by the lifting device 1 is reduced without affecting the lifting of the outer sealing plate.

[0038] Further, the guide rail 14 is also provided with two folding edges 142;

[0039] The long edges of the folding edges 142 are connected to the left groove wall or right groove wall of the guide groove 141, and the folding edges 142 extend along the length direction of the guide rail 14. The two folding edges 142 extend from the left and right sides to the middle part of the guide groove 141 respectively, and the fixed shaft 16 is located between the two folding edges 142.

[0040] As shown in Figure 2 , the pulley 12 can be prevented from coming out of the guide groove 141 during operation by the blocking of the two folding edges 142, thereby ensuring the stability of the lifting operation of the mounting frame 15.

[0041] 3. The outer sealing plate lifting device for glass toughening furnace according to claim 1, characterized in that a plurality of groups of the driving assembly 11 are provided, and each group of the driving assembly 11 comprises a driving motor 111, a transmission rod 112 and two reels 113.

[0042] One end of the transmission rod 112 is in transmission connection with the output end of the driving motor 111, the other end of the transmission rod 112 extends in the front-rear direction, and the transmission rod 112 is arranged close to the left side edge and right side edge of the top surface of the glass toughening furnace.

[0043] The two reels 113 are sleeved on the outer periphery of the transmission rod 112 at intervals in the front-rear direction, the outer periphery of the reel 113 is wound with the cable 13, and the outer periphery of the reel 113 is the output end of the driving assembly 11.

[0044] like Figure 1 As shown, the drive motor 111 drives the corresponding transmission rod 112 to rotate, so that the transmission rod 112 drives the two corresponding reels 113 to rotate, so that the corresponding reels 113 wind up or unwind the cable 13, thereby raising or lowering the corresponding mounting frame 15.

[0045] like Figure 3 The prior art outer sealing plate lifting device 1' shown has a drive assembly 11' including multiple drive cylinders 111' and transmission gears 112'. The output end of the slide rod 1111' of the drive cylinder 111' is connected to one end of the transmission chain 12'. The other end of the transmission chain 12' passes over the transmission gear 112' from above and is connected to the top of the mounting frame 15. This allows the drive cylinder 111' to drive the transmission chain 12' to move along the wheel surface of the transmission gear 112' via the slide rod 1111', thereby driving the mounting frame 15 to move up and down. However, since the distance between the output end of the slide rod 1111' and the transmission gear 112' is limited by the width of the top surface of the frame 2, the range of motion of the mounting frame 15 is limited, and the lifting stroke of the mounting frame 15 is not large.

[0046] Therefore, compared with the existing chain drive structure, using the reel 113 to drive the cable 13 to lift the mounting frame 15 can give the mounting frame 15 a larger lifting stroke and reduce the cost of the lifting device 1.

[0047] Preferably, the pulley 12 is a bearing, and the cable 13 is a stainless steel wire rope.

[0048] like Figure 1 As shown, using bearings as pulley 12 can give pulley 12 better flexibility and a longer service life; cable 13 is stainless steel wire rope, which is not easy to be corroded or rusted and has a good service life.

[0049] Preferably, the drive motor 111 is a servo motor with a gearbox.

[0050] like Figure 1 As shown, using a servo motor with a gearbox as the drive motor 111 can improve the dynamic stability and accuracy of the lifting stroke of the outer sealing plate, and give the drive motor 111 a longer service life.

[0051] In summary, such as Figures 1-4The embodiment of the utility model discloses the outer sealing plate lifting device for glass toughening furnace, the guide groove 141 is seted up in guide rail 14, the pulley 12 is arranged in the guide groove 141, can utilize drive assembly 11 to drive mounting bracket 15 to move up and down along the guide groove 141 through cable 13, in order to make the guide groove 141 close to the outer side of glass toughening furnace, can according to the component arrangement of the outer side of glass toughening furnace to the guide groove 141 corresponding bending, thereby can reduce the space of lifting device 1 occupied under the condition of not affecting the outer sealing plate lifting.

[0052] The technical principles of the utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the utility model and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanations here, other specific embodiments of the utility model can be conceived by those skilled in the art without creative labor, and these embodiments will all fall within the protection scope of the utility model.
