[0002] During the manufacturing process of composite rock wool boards, by evenly applying mortar to the surface of the rock wool board, not only can the bonding force between the rock wool board and the outer protective material be enhanced to ensure the stability of the structure of the composite rock wool board, but also a certain protective effect can be exerted on the rock wool board to improve its durability. The size specifications of rock wool boards are rich and diverse, while most of the conveyor belts of current mortar coating devices are designed with a fixed width. When conveying rock wool boards of different sizes and performing mortar coating operations, mortar is very likely to overflow from the sides of the rock wool board.

Specifically, when the gap adjusting block 8 rises within the lower material guiding cavity 6, the sizing gap 9 increases; when the gap adjusting block 8 descends within the lower material guiding cavity 6, the sizing gap 9 decreases. The flow rate of the mortar is controlled by controlling the sizing gap 9. Specifically, a mortar guiding bottom plate 10 is provided between the sizing groove 7 and the conveyor belt 1. The mortar guiding bottom plate 10 is inclined. The mortar guiding bottom plate is used to guide the mortar onto the rock wool board.

The rock wool board is placed on the conveyor belt 1, and during the process of the conveyor belt 1 transporting the rock wool board, a layer of fiberglass mesh separator cloth is covered on the rock wool board (the covering of the fiberglass mesh separator cloth is an existing technology); then the height of the intermittent adjusting block within the lower material guiding cavity 6 is adjusted to adjust the sizing gap 9. Mortar is added into the upper material storage cavity 5. The mortar falls onto the mortar guiding bottom plate 10 along the sizing gap 9 and the sizing groove 7, and under the guidance of the upper sizing interval 12 formed by the mortar guiding side plate 11 and the mortar guiding bottom plate 10, the rock wool board transported by the conveyor belt 1 is sized.

[0025] Specifically, referring to Figure 2 and Figure 3 , in this embodiment, a mortar coating device for manufacturing composite rock wool boards further includes a position adjusting mechanism 13. The sizing box 4 is connected to the position adjusting mechanism 13. The position adjusting mechanism 13 is used to adjust the relative position of the sizing box 4 and the upper sizing interval 12. When the position adjusting mechanism 13 drives the sizing box 4 to reciprocate above the mortar guiding bottom plate 10, the mortar can be evenly laid in the upper sizing interval 12 and evenly sized onto the rock wool board through the upper sizing interval 12.

[0026] Specifically, referring to Figures 2 - 4, in this embodiment, the position adjustment mechanism 13 includes a position adjustment motor 14, a position adjustment screw 15, a position adjustment slide bar 16, and a position adjustment block 17.

[0027] During use, the moving range of the sizing box 4 is adjusted according to the distance between the two guide slurry side plates 11. Specifically, the position adjustment motor 14 is started, the position adjustment motor 14 drives the position adjustment screw 15 to rotate, and under the drive of the position adjustment screw 15 and the guiding action of the position adjustment slide bar 16, the position adjustment block 17 is driven to move. The position adjustment block 17 drives the sizing box 4 to reciprocate, and thus the adjustment of the moving range of the sizing box 4 can be realized. During the reciprocating movement of the sizing box 4, the mortar in the sizing box 4 is evenly sized to the sizing interval 12.

[0028] Specifically, refer to Figure 4 , Figure 6 and Figure 7 , in this embodiment, a drive box 18 is fixedly arranged in the sizing box 4. An elevating mechanism 19 is arranged in the drive box 18.

Under the lifting drive of the elevating screw 22 and the guiding action of the guiding slide bar 23, the height of the gap adjustment block 8 is adjusted, so as to realize the adjustment of the sizing gap 9. At the same time, it should be noted that before adjusting the height position of the gap adjustment block 8 each time, the inside of the sizing box 4 needs to be thoroughly cleaned to avoid mortar being embedded in the threads of the elevating screw 22 and ensure that the threaded cylinder 21 can smoothly drive the elevating screw 22 to rise and fall during subsequent work.

[0030] Specifically, refer to Figure 4 and Figure 6, in this embodiment, the top wall of the driving box 18 is arranged in a herringbone structure, and the size of the bottom wall of the driving box 18 is larger than the size of the upper end of the gap adjusting block 8. The mortar in the upper storage box is smoothly guided to the sizing gap 9 through the herringbone structure arrangement, and the mortar is prevented from falling onto the upper end of the gap adjusting block 8 by the size difference between the bottom wall of the driving box 18 and the upper end of the gap adjusting block 8.
