[0029] The feeding conveyor 1 is used to convey the gypsum board, and then the gypsum board is clamped by the indentation mechanism 5 and a breaking indentation is punched on the gypsum board, and then the gypsum board is broken by the breaking mechanism 4.

[0030] The indentation mechanism 5 includes a left pressure plate device 51, a right pressure plate device 52, a hinged plate 53 and an indentation and trimming device 54. The left pressure plate device 51 and the right pressure plate device 52 are installed on the breaking mechanism 4 and are respectively arranged on the left and right sides of the indentation and trimming device 54 and are used to press the gypsum board. One end of the two hinged plates 53 is movably connected to the two sides of the left pressure plate device 51 and the other end is slidably connected to the two sides of the right pressure plate device 52. The indentation and trimming device 54 is installed on the left pressure plate device 51 and is used to press the breaking marks of the gypsum board; the left pressure plate device 51 and the right pressure plate device 52 both include a pressure plate cylinder 55, an upper pressure plate 56, a fixing frame 57 and a lower pressure plate 58. At least one pressure plate cylinder 55 is installed on the fixing frame 57 and the piston rod is connected to the upper pressure plate 56. The lower pressure plate 58 is installed on the fixing frame 57 and is located below the upper pressure plate 56.

[0031] Specifically, the two parts of the gypsum board are clamped by the left pressure plate device 51 and the right pressure plate device 52, and the indentation and trimming device 54 is used to punch and break the gypsum board between the left pressure plate device 51 and the right pressure plate device 52; the right pressure plate device 52 is driven by the breaking mechanism 4 through the hinged plate 53 to break the gypsum board, wherein the hinged plate 53 and the right pressure plate device 52 are preferably connected by a dovetail groove and a dovetail slide rail, which can ensure that while one end of the hinged plate 53 is hinged and rotated, the other end of the sliding end is stable and will not change due to rotation; when the left pressure plate device 51 and the right pressure plate device 52 clamp the gypsum board, the upper pressure plate 56 is driven downward by the pressure plate cylinder 55, so that the gypsum board is pressed between the upper pressure plate 56 and the lower pressure plate 58.

[0032] In another embodiment of the present invention, the indentation and trimming device 54 includes a slider 510, an indentation knife 511, an indentation cylinder and a fixed press frame, the fixed press frame is installed on the fixed frame 57, the slider 510 is slidably connected to the fixed press frame, the indentation cylinder is installed on the fixed press frame and the piston rod is connected to the slider 510, and the indentation knife 511 is connected to the slider 510.

[0033] Specifically, the slider 510 is driven up and down by the indentation cylinder, so that the indentation knife 511 punches the gypsum board to form a breaking indentation, so that when the gypsum board is bent, the breaking part breaks along the breaking indentation.

[0034] In another embodiment of the present invention, cutting plates 512 are connected to both sides of the creasing knife 511, and the cutting plates 512 are tilted toward the side of the gypsum board.

[0035] Specifically, after the gypsum board is broken, the breaking mechanism 4 drives the gypsum board to restore the horizontal conveying state, and then drives the cutting plate 512 to continue to descend through the slider 510 to cut off the broken section of the gypsum board to ensure the beauty of the broken surface of the gypsum board; by setting the cutting plate 512 close to the side of the gypsum board into an inclined shape, the shear surface of the gypsum board is reduced to reduce the thrust of the indentation cylinder, avoiding the use of a high-thrust indentation cylinder; the indentation processing has two action states, first, the distance between the upper pressing plates 56 of the left pressing plate device 51 and the right pressing plate device 52 is just enough for the indentation knife 511 to pass through to complete the breaking indentation processing, and then the distance between the upper pressing plates 56 of the left pressing plate device 51 and the right pressing plate device 52 is increased so that the indentation knife 511 and the cutting plate 512 can pass smoothly; second, the distance between the upper pressing plates 56 of the left pressing plate device 51 and the right pressing plate device 52 is directly controlled to just pass through the indentation knife 511 and the cutting plate 512.

[0036] In another embodiment of the present invention, a relief arc angle 59 is provided on the lower side of one end of the lower pressing plate 58 close to the indentation and trimming device 54 .

[0037] Specifically, by setting the avoidance arc angle 59 , when the right pressing plate device 52 is driven by the breaking mechanism 4 to break the gypsum board, the lower pressing plate 58 of the right pressing plate device 52 will not collide with the lower pressing plate 58 of the left pressing plate device 51 .

[0039] Specifically, after the gypsum board is transported through the left pressure plate device 51 and the right pressure plate device 52, when the gypsum board is clamped by the left pressure plate device 51 and the right pressure plate device 52, its power motor 411 synchronously drives the screw rod 410 to rotate, so that the adjustment base 48 drives the sliding frame 41, the breaking frame 44, the left pressure plate device 51 and the right pressure plate device 52 to move synchronously, so that the left pressure plate device 51 and the right pressure plate device 52 are synchronized with the movement speed of the gypsum board; then the breaking cylinder 43 drives one end of the breaking frame 44 to descend, so that the right pressure plate device 41 at the other end of the breaking frame 44 is movably connected. 52 rotates around the movable connection end of the hinged plate 53. During the rotation, the clamping angle of the right pressure plate device 52 changes to achieve the purpose of breaking the gypsum board. After the gypsum board is broken, the breaking cylinder 43 drives the breaking frame 44 to restore the horizontal installation. At the same time, the power cylinder 412 drives the right pressure plate device 52 to move to control the distance between the left pressure plate device 51 and the right pressure plate device 52, so that the indentation knife 511 and the cutting plate 512 pass through between the left pressure plate device 51 and the right pressure plate device 52, so that the cutting plate 512 can cut the broken surface of the gypsum board to ensure the flatness of the broken surface.

[0040] In another embodiment of the present invention, a positioning roller 47 is mounted on the sliding frame 41 , and an L-shaped positioning frame 46 is mounted on the breaking frame 44 and cooperates with the positioning roller 47 .

[0041] Specifically, when the breaking cylinder 43 drives one end of the breaking frame 44 to rise and make the breaking frame 44 horizontal, it is hung on the positioning roller 47 through the L-shaped positioning frame 46 to ensure that the breaking frame 44 quickly returns to a horizontal state.

[0042] In another embodiment of the present invention, guide rollers 513 are installed on both the fixing frame 57 and the adjusting base frame 48 of the right pressure plate device 52 .

[0043] Specifically, the gypsum board is transported and pulled by the guide roller 513 so that the gypsum board smoothly enters between the upper pressing plate 56 and the lower pressing plate 58 .

[0044] In another embodiment of the present invention, an infrared positioning sensor is installed on the breaking frame 44.

[0045] Specifically, the position of the gypsum board is sensed by an infrared positioning sensor to achieve synchronous start-up of the power motor 411 and the pressure plate cylinder 55 .

[0046] In another embodiment of the present invention, a polyurethane rubber sheet is connected to the side of the upper pressing plate 56 close to the lower pressing plate 58 .

[0047] Specifically, the upper pressing plate 56 is in contact with the gypsum board through the contact between the PU board and the gypsum board, so as to ensure soft contact between the upper pressing plate 56 and the gypsum board, thereby avoiding damage to the gypsum board caused by hard contact.
