TECHNICAL FIELD

[0001] The utility model relates to the technical field of gypsum board forming, specifically to a gypsum board extrusion forming device. BACKGROUND

[0002] Gypsum board is a kind of building material that is widely used, which is usually formed by filling gypsum between two layers of paperboard. The paperboard provides strength, and the gypsum core is responsible for sound insulation, fireproofing and other functions. Gypsum board has been widely used in interior partition walls, wall covering panels (instead of wall plastering layer), ceilings, sound-absorbing panels, ground base panels and various decorative panels of various buildings such as houses, office buildings, shops, hotels and industrial plants.

[0003] At present, the patent with publication number CN212498229U discloses a gypsum board extrusion forming device, which includes an extrusion mechanism, a slitting mechanism and a driving mechanism. The extrusion mechanism includes an upper extrusion plate and a base arranged below the upper extrusion plate. The slitting mechanism includes a frame-type closed structure cutter and a frame-type fixed plate. The cutter is fixedly installed at the bottom of the frame-type fixed plate, and the frame-type fixed plate is arranged between the upper extrusion plate and the base. The driving mechanism includes a hydraulic cylinder, a first guide rod, a first spring, a second guide rod and a second spring. The hydraulic cylinder is arranged above the upper extrusion plate and the piston rod is fixedly connected with the upper extrusion plate. The upper extrusion plate is slidably arranged above the frame-type fixed plate through the first guide rod. The first spring is sleeved between the first guide rods and located between the upper extrusion plate and the frame-type fixed plate. The frame-type fixed plate is slidably arranged above the base through the second guide rod. The second spring is sleeved outside the second guide rod and located between the base and the frame-type fixed plate. The corresponding cutting, fixing and extrusion forming work can be completed by using only one hydraulic cylinder, which simplifies the control operation and equipment, reduces the equipment cost, and compresses the installation space.

[0004] However, the gypsum board extrusion forming device still has the following problems in use: In the process of extruding and forming the gypsum, a direct extrusion method is adopted.
