Under the telescopic action of the telescopic slide 21, the mounting plate 2 can be close to or away from the drying box 1, so as to facilitate the installation of the ceramic insulation board.

[0053] There are multiple clamping assemblies 3 and clamping and abutting assemblies 7, which are arranged opposite to each other in a one-to-one correspondence. The clamping assembly 3 is arranged on the side of the mounting plate 2 close to the inside of the drying box 1, and the clamping and abutting assemblies 7 are arranged on the side wall of the drying box 1 opposite to the mounting plate 2. The clamping assembly 3 is used to clamp the ends of ceramic insulation boards of different sizes, and the clamping and abutting assemblies 7 are used to elastically abut the other ends of ceramic insulation boards of different sizes.

[0054] In this application, reference is made to Figure 3 The clamping assembly 3 includes a clamping plate 31 , a clamping rod 32 and a clamping head 33 .

[0055] Reference Figure 2 and Figure 3 The clamping plate 31 is in the shape of a circular plate and is connected to the mounting plate 2; one end of the clamping rod 32 is rotatably connected to the clamping plate 31, and four clamping rods 32 are provided, and the rotating ends of the four clamping rods 32 are evenly arranged around the center of the clamping plate 31; the clamping head 33 is L-shaped and is provided with four clamping heads 33, and the clamping heads 33 correspond to the clamping rods 32 one by one. The clamping heads 33 are rotatably connected with a rectangular block-shaped slider 331, and the slider 331 is slidably arranged in the first sliding groove 321 opened on the clamping rod 32 along the direction approaching or away from the rotating end of the clamping rod 32.

[0056] The four clamping rods 32 are swung to adjust the rotation angle of the clamping rods 32 so that the clamping rods 32 are aligned with the top angle of the end of the ceramic insulation board. The clamping heads 33 are slid to adjust the distance between the clamping heads 33 and the rotation end of the clamping rods 32 so that the clamping heads 33 can be clamped at the top angle position of the end of the ceramic insulation board. Thus, by adjusting the positions of the clamping rods 32 and the clamping heads 33, ceramic insulation boards of different sizes can be clamped and fixed on the clamping plate 31, thereby realizing the installation of ceramic insulation boards of different sizes on the mounting plate 2.

[0057] Further, refer to Figure 3 A first adjusting component 4 is provided between the clamping plate 31 and the four clamping rods 32, and the first adjusting component 4 is used to synchronously adjust the rotation angle of the four clamping rods 32. A second adjusting component 5 is provided between the clamping plate 31 and the four clamping heads 33, and the second adjusting component 5 is used to synchronously adjust the sliding positions of the four clamping heads 33. Through the first adjusting component 4 and the second adjusting component 5, the positions of the clamping rods 32 and the clamping heads 33 can be adjusted so that the clamping rods 32 and the clamping heads 33 can cooperate to fix ceramic insulation boards of different sizes on the clamping plate 31.

[0058] Specifically, refer to Figure 4 The first adjusting assembly 4 includes a first gear 41 , a first rack 42 and an adjusting rod 43 .

[0059] The first gear 41 is rotatably connected to the clamping plate 31. Two first racks 42 and adjusting rods 43 are provided, and they correspond one to one. The adjusting rods 43 are fixedly connected to the first racks 42. The two first racks 42 are centrally symmetrically arranged on both sides of the first gear 41. The two first racks 42 are meshed with the first gear 41. The first racks 42 are slidably connected to the clamping plate 31. One of the adjusting rods 43 is located between two adjacent clamping rods 32, and the other adjusting rod 43 is located between the other two clamping rods 32. The adjusting rods 43 are vertically arranged. The two ends of the adjusting rod 43 are fixedly connected with a circular rod-shaped sliding rod 431. The two sliding rods 431 are respectively slidably set in the second sliding grooves 322 opened on the two clamping rods 32 close to the adjusting rod 43. The first gear 41 drives the two first racks 42 to enable the two adjusting rods 43 to move towards or away from each other. The adjusting rod 43 drives the two clamping rods 32 connected to it to swing to adjust the swing angle of the clamping rod 32, so that the clamping rod 32 can easily face the top angle of the end of the ceramic insulation board after adjustment.

[0060] Specifically, refer to Figure 3 The second adjusting component 5 includes an adjusting disk 51, an adjusting rope 52 and an adjusting spring 53.

Four adjusting ropes 52 and adjusting springs 53 are each provided, and each corresponds to the slider 331 one by one. The adjusting rope 52 is fixedly connected between the slider 331 and the adjusting disk 51. The adjusting spring 53 is located in the first sliding groove 321 and is located at one end of the slider 331 close to the rotating end of the clamping rod 32. The adjusting spring 53 is fixedly connected between the slider 331 and the side wall of the first sliding groove 321. The adjusting spring 53 is used to drive the slider 331 to slide away from the rotating end of the clamping rod 32. When the adjusting spring 53 drives the slider 331 to slide to the position farthest from the rotating end of the clamping rod 32, the connection point of the adjusting rope 52 and the adjusting disk 51 is located on the rotation axis of the clamping rod 32.

[0061] Before the initial adjustment, since the connection point between the adjusting rope 52 and the adjusting disk 51 is located on the rotation axis of the clamping rod 32, when the rotation angle of the clamping rod 32 is adjusted, the adjusting rope 52 can rotate with the clamping rod 32 with the connection point with the adjusting disk 51 as the swing center, so that the rotation of the clamping rod 32 is not easy to interfere with the position of the adjusting rope 52; when it is necessary to clamp the ceramic heat insulation board, the adjusting disk 51 is rotated, and the adjusting disk 51 can drive the adjusting rope 52 to move, and the adjusting rope 52 pulls the slider 331 to slide in the first slide groove 321, and the adjusting spring 53 accumulates. By storing elastic force, the slider 331 drives the clamping head 33 to move toward the direction close to the rotation axis of the clamping rod 32, so that the clamping head 33 can be squeezed at the top angle position of the ceramic insulation board to fix the ceramic insulation board; when it is necessary to release the clamping of the ceramic insulation board, the adjusting disk 51 is rotated in the opposite direction, and the slider 331 slides in the direction away from the rotation end of the clamping rod 32 under the action of the elastic force of the adjusting spring 53, so that the clamping head 33 is away from the ceramic insulation board to release the ceramic insulation board; thereby, the clamping head 33 can clamp ceramic insulation boards of different sizes.

[0062] Furthermore, refer to Figure 3 and Figure 5 The first adjustment component 4 and the second adjustment component 5 are commonly connected with a driving component 6, and the driving component 6 includes a driving part 61 and a fixing part 62.

[0065] Specifically, refer to Figure 2 , Figure 3 and Figure 5 The driving part 61 includes a driving rod 611, a first transmission block 612 and a second transmission block 613. The driving rod 611 is in the shape of a round rod. The driving rod 611 is penetrated on the clamping plate 31 and the mounting plate 2, and is connected with the clamping plate 31 and the mounting plate 2 by a cylindrical sleeve pair. The driving rod 611 is also penetrated in a first adjustment hole 411 opened on the first gear 41 and a second adjustment hole 511 opened on the adjustment disk 51. One end of the driving rod 611 located outside the drying box 1 is fixedly connected with a hand wheel 6111; the first transmission block 612 and the second transmission block 613 are both fixedly arranged on the driving rod 611. The first transmission block 612 and the second transmission block 613 are fixedly arranged on the driving rod 611. 12 and the second transmission block 613 have a coordination spacing, the coordination spacing is greater than the distance between the first gear 41 and the adjusting disk 51 away from each other, the first transmission block 612 is located between the second transmission block 613 and the clamping plate 31; the first transmission block 612 and the second transmission block 613 are both regular hexagonal blocks, the first adjusting hole 411 and the second adjusting hole 511 are both regular hexagonal, the first transmission block 612 is adapted to the first adjusting hole 411, the second transmission block 613 is adapted to the second adjusting hole 511, and a space for the first transmission block 612 to move is reserved between the first gear 41 and the clamping plate 31.

[0066] The user holds the hand wheel 6111 to make the driving rod 611 slide and rotate on the clamping plate 31 and the mounting plate 2. When the first gear 41 needs to be driven, the driving rod 611 is slid to make the first transmission block 612 slide into the first adjustment hole 411, and the driving rod 611 is rotated. The driving rod 611 drives the first transmission block 612 to rotate, and the first transmission block 612 can drive the first gear 41 to rotate; when the adjustment disk 51 needs to be driven, the driving rod 611 is slid to make the second transmission block 613 slide into the second adjustment hole 51 1, the driving rod 611 is rotated, the driving rod 611 drives the second transmission block 613 to rotate, and the second transmission block 613 can drive the adjustment disk 51 to rotate; when the first gear 41 and the adjustment disk 51 do not need to be driven, the adjustment spacing is made to correspond to the first gear 41 and the adjustment disk 51, so that the first gear 41 and the adjustment disk 51 can be in a free rotation state, thereby realizing the separate driving of the first gear 41 and the adjustment disk 51 through a driving rod 611, so that the positions of the clamping rod 32 and the clamping head 33 are easy to adjust.

[0067] Specifically, refer to Figure 3 and Figure 5 The first fixing portion 62 and the second fixing portion 62 have exactly the same structure, and the only difference is whether they are connected to the first gear 41 or the adjusting disk 51. Therefore, in this embodiment, the first fixing portion 62 is taken as an example for detailed description.

[0068] Reference Figure 5 The first fixing part 62 includes a fixing ball 621 , a first fixing rod 622 , a fixing spring 623 , a second fixing rod 624 , a fixing head 625 and a fixing ring 626 .

[0069] The fixing ball 621 is slidably disposed in a fixing groove 412 provided on the side wall of the first adjustment hole 411, and the fixing groove 412 is located at one of the side edges of the first adjustment hole 411. The first fixing rod 622 is located in the fixing groove 412 and is fixedly connected to the fixing ball 621. The fixing spring 623 is fixedly disposed between the first fixing rod 622 and the bottom of the fixing groove 412, and the fixing spring 623 is used to drive the fixing ball 621 to slide out of the fixing groove 412.

[0070] The second fixing rod 624 is slidably disposed in the fixing hole 413 provided on the side wall of the fixing groove 412. The fixing hole 413 penetrates to the side of the first gear 41 close to the clamping plate 31. The end of the second fixing rod 624 close to the first fixing rod 622 is fixedly connected to the first fixing rod 622. The fixing head 625 is in a round block shape and is fixedly connected to the end of the second fixing rod 624 away from the first fixing rod 622. The fixing ring 626 is located between the first gear 41 and the clamping plate 31. The fixing ring 626 is fixedly connected to the clamping plate 31. A plurality of fixing slots 6261 are provided on the outer side wall of the fixing ring 626 in the circumferential direction. The fixing head 625 is adapted to the fixing slots 6261. The fixing head 625 is used to be clamped in one of the fixing slots 6261 to limit the rotation of the first gear 41 relative to the clamping plate 31.

[0071] Among them, refer to Figure 3 and Figure 5 The fixed head 625 is made of a high expansion alloy, such as Cu60Zn40, FeNi22Cr3 or FeNi20Mn6. The fixed head 625 made of a high expansion alloy has the characteristic of a high thermal expansion coefficient. When hot air is dried, the hot air can heat the fixed head 625. After being heated, the fixed head 625 can expand and squeeze into the fixed slot 6261, so that the clamping connection between the fixed head 625 and the fixed slot 6261 is stable and reliable, so that when the ceramic insulation board is dried, the clamping rod 32 and the clamping head 33 are not easy to loosen the ceramic insulation board.

[0072] After the first transmission block 612 escapes from the first adjustment hole 411, the fixing spring 623 can drive the first fixing rod 622 to slide through the elastic force, so that the fixing ball 621 slides out of the fixing groove 412, and the first fixing rod 622 drives the second fixing rod 624 to slide, so that the fixing head 625 connected to the second fixing rod 624 is clamped in one of the fixing grooves 6261 on the fixing ring 626, and the fixing head 625 is clamped in the fixing groove 6261, so that the first gear 41 is difficult to rotate relative to the clamping plate 31, thereby fixing the position of the clamping rod 32, so that the clamping rod 32 is easy to be automatically fixed after adjustment; After a transmission block 612 slides into the first adjustment hole 411, the first transmission block 612 can squeeze the fixing ball 621 to slide into the fixing groove 412, and the fixing ball 621 drives the first fixing rod 622 to slide, and the first fixing rod 622 drives the second fixing rod 624 to slide, and the second fixing rod 624 drives the fixing head 625 to escape from the fixing slot 6261 to release the fixation of the first gear 41 and the clamping plate 31, so that the first transmission block 612 can drive the first gear 41 to rotate to adjust the rotation angle of the clamping rod 32, so that the rotation state and the fixed state of the first gear 41 can be automatically switched.

[0073] In this application, reference is made to Figure 2 and Figure 6The clamping assembly 7 includes a clamping telescopic rod 71, a clamping plate 72 and a clamping spring 73. The clamping telescopic rod 71 is connected to the side wall of the drying box 1; the clamping plate 72 is fixedly connected to the movable end of the clamping telescopic rod 71, and the clamping plate 72 is used to press against the end of the ceramic insulation board away from the clamping assembly 3; the clamping spring 73 is fixedly arranged between the rod body of the clamping telescopic rod 71 and the clamping plate 72, and the clamping spring 73 is used to drive the clamping telescopic rod 71 to extend; when the ceramic insulation board is clamped and installed on the clamping assembly 3, the sliding mounting plate 2 allows the ceramic insulation board to enter the drying box 1, and the end of the ceramic insulation board away from the clamping plate 31 can be squeezed on the clamping plate 72. Under the elastic force of the clamping spring 73, the clamping plate 72 presses against the ceramic insulation board, thereby improving the fixing effect of the ceramic insulation board.

[0074] Further, refer to Figure 2 The mounting plate 2 is rotatably connected to two connecting bolts 22, and the connecting bolts 22 are used to be threadedly connected to the drying box 1 so that the mounting plate 2 and the drying box 1 can be fixed.

[0075] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The clamping plate 31 is rotatably connected to the mounting plate 2, the clamping telescopic rod 71 is rotatably connected to the drying box 1, and all the clamping telescopic rods 71 ​​are commonly connected to the third adjustment component 8, which is used to drive the clamping telescopic rod 71 to rotate 180 degrees, so that the ceramic insulation board can be dried from two opposite sides. The third adjustment component 8 is connected to the heat drive component 9, which is used to drive the third adjustment component 8 to operate with the heat of the hot air in the drying box 1, so that the third adjustment component 8 does not need an additional power source, effectively utilizes the drying hot air, and improves the energy utilization efficiency.

[0076] Specifically, refer to Figure 1 and Figure 2 , multiple clamping telescopic rods 71 ​​are arranged in multiple rows, and two adjacent rows of clamping telescopic rods 71 ​​are arranged in a staggered manner, so that the hot air of drying can blow through the end of each ceramic insulation board. The third adjustment component 8 includes a second gear 81, a second rack 82, a connecting rod 83 and an adjusting telescopic rod 84. There are multiple second gears 81, and they are fixed on the clamping telescopic rod 71 one by one; there are multiple second racks 82, and they correspond to multiple rows of second gears 81 one by one. The second racks 82 are slidably set on the drying box 1 and mesh with all the second gears 81 in the corresponding row; the connecting rod 83 is fixedly connected to all the second racks 82; the adjusting telescopic rod 84 is fixedly set on the outer wall of the drying box 1, and the movable end of the adjusting telescopic rod 84 slides into the drying box 1, and the movable end of the adjusting telescopic rod 84 is fixedly connected to the connecting rod 83.

[0077] When the telescopic rod 84 is extended, the telescopic rod 84 can drive the connecting rod 83 to move, and the connecting rod 83 can synchronously drive all the second racks 82 to slide, and the second racks 82 drive all the second gears 81 engaged with themselves to rotate, so that the second gears 81 drive the clamping telescopic rod 71 to rotate, thereby allowing the ceramic insulation board to rotate during drying.

[0078] Specifically, refer to Figure 1 and Figure 2 The heat drive assembly 9 includes a water tank 91, a heat conducting plate 92 and a steam pipe 93. One side of the water tank 91 is open and connected to the bottom of one side of the drying box 1. The heat conducting plate 92 is fixedly arranged at the connection between the water tank 91 and the drying box 1, and closes the connection between the water tank 91 and the drying box 1. The heat conducting plate 92 is made of a material with excellent thermal conductivity, such as aluminum or copper. The water tank 91 is used to hold water. One end of the steam pipe 93 is connected to the top of the water tank 91, and the other end is connected to the rodless cavity of the adjustable telescopic rod 84. Air is sealed in the rod cavity of the adjustable telescopic rod 84.

[0079] The hot air transfers heat to the water in the water tank 91 through the heat conducting plate 92. The water absorbs the heat and starts to heat up, and gradually boils and evaporates. The water vapor flows from the steam pipe 93 to the rodless cavity of the adjustable telescopic rod 84 to drive the adjustable telescopic rod 84 to extend, so that the extension power of the adjustable telescopic rod 84 can be assisted by the heat of the drying hot air.

[0080] After the drying is stopped, the water vapor in the non-rod cavity of the adjusting telescopic rod 84 is gradually liquefied and flows back into the water tank 91, and the air in the rod cavity of the adjusting telescopic rod 84 enables the adjusting telescopic rod 84 to automatically reset.

[0081] The implementation principle of a drying device for forming ceramic insulation boards in an embodiment of the present application is as follows: when in use, slide out the mounting plate 2, place the ceramic insulation board between the four clamping heads 33, drive the clamping rod 32 and the clamping head 33 to move, so that the clamping head 33 stably clamps the end of the ceramic insulation board, so that the ceramic insulation board is fixed on the clamping plate 31, and then the ceramic insulation board enters the drying box 1, the ceramic insulation board is squeezed on the clamping plate 72, and hot air is introduced into the drying box 1 from the drying air nozzle 11. The hot air dries the ceramic insulation board and heats the water in the water tank 91. The water vapor generated by the water drives the adjustable telescopic rod 84 to extend, and the adjustable telescopic rod 84 drives the ceramic insulation board to rotate, so that the ceramic insulation board is dried evenly, so that the ceramic insulation board is clamped and fixed by the clamping head 33, thereby meeting the installation requirements of ceramic insulation boards of different sizes on the drying equipment.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
