Move to the surface of the first glue coating roller 8. At this time, during the rotation of the first glue coating roller 8, glue will be coated on the side of the gypsum board. The first glue coating roller 8 is a rubber roller. The edge sealing mechanism includes an edge sealing roller 9, a paper penetration hole 26 and a mounting plate 38. The edge sealing roller 9 is movably connected to the cross bar 2. The two groups of cross bars 2 are fixedly connected to the back surfaces of each other with mounting plates 38. The first waterproof paper cylinder 4 is movably installed on the upper end of the mounting plate 38. The paper penetration hole 26 is provided in the cross bar 2. Before use, the first waterproof paper in the first waterproof paper cylinder 4 needs to be passed through the paper penetration hole 26 and moved to the left side of the edge sealing roller 9. When the side of the gypsum board coated with glue moves to the middle of the two groups of edge sealing rollers 9, the first waterproof paper will be pressed against the side of the gypsum board.

[0036] Both ends of the cutting knife 12 are fixedly connected with a slide bar 14, and the slide bar 14 is slidably connected to the guide groove 22. The guide groove 22 is opened in the U-shaped support plate 13. When the second telescopic cylinder 20 drives the cutting knife 12 to move, the slide bar 14 will move along the guide groove 22. The outer side of the connecting shaft 28 is movably sleeved with a connecting block 27, and the connecting block 27 is slidably connected to the inner side of the slip ring 24. The inner side of the slip ring 24 is fixedly connected with a clamping spring 35, and the other end of the clamping spring 35 is fixedly connected to the connecting block 27. The elastic force of the clamping spring 35 is greater than the elastic force of the reset spring 36 to ensure that when the connecting gear ring 17 rotates counterclockwise, the T-shaped clamping rod 30 is separated from the clamping hole 34. Due to the elastic force of the clamping spring 35, the clamping roller 21 and the guide roller 23 are tightly fitted together, so that the force generated when the T-shaped clamping rod 30 is separated from the clamping hole 34 will not drive the clamping roller 21 to rotate;

[0037] Under the elastic force of the compression spring 35, the compression roller 21 will always be in contact with the guide roller 23;

[0038] The conversion mechanism includes a connecting gear ring 17 and a plurality of groups of T-shaped clamping rods 30.

The other end of the reset spring 36 is fixedly connected to the T-shaped clamping rod 30. The connecting gear ring 17 is meshed with the tooth plate 32. When the cutting knife 12 moves upward, the connecting gear ring 17 will start to rotate along the tooth plate 32. When the connecting toothed ring 17 rotates clockwise, the T-shaped clamping rod 30 clamped in the clamping hole 34 will not disengage, and the connecting toothed ring 17 will drive the pressing roller 21 to start rotating, and the pressing roller 21 rotates to convey the second waterproof paper in the second waterproof paper tube 19 downward, so that the second waterproof paper moves to the position of the edge pressing plate 16. When the cutting knife 12 moves downward again, the connecting toothed ring 17 will rotate counterclockwise. Since one side of the clamping hole 34 and the clamping end of the T-shaped clamping rod 30 are both inclined, during the counterclockwise rotation of the connecting toothed ring 17, the T-shaped clamping rod 30 will disengage from the clamping hole 34, so that the counterclockwise rotation of the connecting toothed ring 17 will not drive the pressing roller 21 to rotate;

[0039] The edge pressing mechanism includes an edge pressing plate 16, and a first telescopic cylinder 15 is fixedly installed on the side of the cutting knife 12 away from the edge pressing plate 16, and the output end of the first telescopic cylinder 15 penetrates the cutting knife 12 and is fixedly connected to the edge pressing plate 16;

[0040] A second telescopic cylinder 20 is fixedly connected to the upper end of the U-shaped support plate 13. The output end of the second telescopic cylinder 20 passes through the U-shaped support plate 13 and is fixedly connected to the upper end of the cutting knife 12. A clearance hole 11 is provided on the lower side of the cutting knife 12. The clearance hole 11 is opened in the upper end of the support plate 3. The clearance hole 11 can make way for the cutting knife 12.

[0041] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a gypsum board production method, including the above-mentioned gypsum board production device, including:

[0042] S1, conveying the formed gypsum board to the upper end of the support plate 3 by the gypsum board forming machine 1, guiding the gypsum board by the L-shaped guide plate 5, cutting the side of the gypsum board guided by the L-shaped guide plate 5 by two sets of cutting machines 6, and when the gypsum board with the cut side moves to between the two sets of cross bars 2, the gluing mechanism glues the cut side of the gypsum board, and the edge sealing mechanism performs edge sealing on the side of the gypsum board after gluing;

[0043] S2, the second telescopic cylinder 20 is opened to drive the cutting knife 12 to move downward to cut the gypsum board. After the gypsum board is cut, the second waterproof paper coated with glue is pressed into the cut surface of the gypsum board by opening the edge pressing mechanism, and the second waterproof paper is cut at the same time. After the cutting is completed, the second telescopic cylinder 20 drives the cutting knife 12 to move upward;

[0044] S3. Through the connection between the conversion mechanism and the tooth plate 32, when the cutting knife 12 moves upward, the pressing roller 21 can rotate clockwise, thereby driving the second waterproof paper in the second waterproof paper tube 19 to move downward. When the cutting knife 12 moves downward, the pressing roller 21 will not rotate under the conversion of the conversion mechanism.

[0045] Working principle: when in use, the gypsum liquid is pressed into a gypsum board by the gypsum board forming machine 1 and transported to the upper end of the support plate 3, and the gypsum transported to the upper end of the support plate 3 is transported by the L-shaped guide plate 5. Under the guidance of the L-shaped guide plate 5, two groups of cutting machines 6 cut the side edges of the gypsum board, and the cut side edges of the gypsum board are discharged to the lower end of the support plate 3 under the guidance of the L-shaped guide plate 7. Under the push of the gypsum board forming machine 1, the gypsum board with the cut side edges will enter between the two groups of cross bars 2. At this time, the first glue coating roller 8 can cut the side edges of the gypsum board, and the edge sealing roller 9 can press the first waterproof paper in the first waterproof paper tube 4 into the side edges of the gypsum board coated with glue, and the side edges of the gypsum board are edge sealed by the first waterproof paper;

[0046] After the side edge sealing is completed, when the gypsum board passes the lower end of the cutting knife 12, the second telescopic cylinder 20 is opened to make the cutting knife 12 move downward to cut the gypsum board. After the cutting is completed, the first telescopic cylinder 15 is opened to drive the edge pressing plate 16 connected to its output end to move. The edge pressing plate 16 moves to press the second waterproof paper in the second waterproof paper tube 19 coated with glue into the cut surface of the gypsum board. At the same time, since the upper end of the edge pressing plate 16 is fixedly connected with a cutting blade, after the edge pressing plate 16 presses the second waterproof paper into the cut surface of the gypsum board, the cutting The cutting blade will cut the second waterproof paper. At this time, the second telescopic cylinder 20 drives the cutting knife 12 to move upward. When the cutting knife 12 moves upward, the connecting toothed ring 17 starts to rotate along the toothed plate 32. When the connecting toothed ring 17 rotates clockwise, the T-shaped clamping rod 30 clamped in the clamping hole 34 will not be disengaged. At this time, the connecting toothed ring 17 drives the pressing roller 21 to start rotating. The pressing roller 21 rotates to transport the second waterproof paper in the second waterproof paper tube 19 downward, so that the second waterproof paper moves to the position of the edge clamping plate 16.

[0047] The liquid guiding funnel 33 located at the lower end of the second liquid storage tank 18 can transport the glue to the outer side of the pressing roller 21. At this time, during the rotation of the pressing roller 21, the glue will be coated on the surface of the second waterproof paper. When the cutting knife 12 moves downward again, the connecting gear ring 17 will rotate counterclockwise. Since one side of the clamping hole 34 and the clamping end of the T-shaped clamping rod 30 are both inclined, during the counterclockwise rotation of the connecting gear ring 17, the T-shaped clamping rod 30 will be disengaged from the clamping hole 34, so that the counterclockwise rotation of the connecting gear ring 17 will not drive the pressing roller 21 to rotate.
