[0016] The present invention will be described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-3 The quartz stone slab pressing and forming mechanism with vacuum function shown in the figure includes a horizontally arranged supporting plate 10, a frame 20 that is movable up and down on the top of the supporting plate 10, a lifting cylinder 30 for driving the frame 20 to move vertically on the supporting plate 10, a pressing head 40 that is movable up and down inside the frame 20, a separation cylinder 50 for driving the pressing head 40 to move vertically in the frame 20, and a conveyor belt 60 for conveying the prefabricated quartz stone slabs between the pressing head 40 and the supporting plate 10.

[0018] The surrounding frame 20 is a rectangular frame with an open top, and the top surfaces of the surrounding frame edges extend inward so that the top opening is smaller than the frame cavity.

[0019] The pressure head 40 includes a rectangular pressing plate 41, an integrally formed top-opening rectangular groove 42 centered on the top of the rectangular pressing plate 41, and a vibration device 43 provided in the rectangular groove 42. The rectangular groove 42 is consistent with the length direction of the rectangular pressing plate 41 but is smaller in length and width than the rectangular pressing plate 41, so that the periphery of the rectangular pressing plate 41 is exposed outside the periphery of the rectangular groove 42; the pressure head 40 is inside the frame 20, the periphery of the rectangular pressing plate 41 is in contact with the inner wall of the frame 20, and the periphery of the rectangular groove 42 is in contact with the top wall of the frame 20, thereby connecting the pressure head 40 to the frame 20 for up and down movement, and separating a closed chamber 70 between the rectangular pressing plate 41 and the inner bottom of the frame 20.

[0020] The separation oil cylinder 50 is vertically arranged inside the long frame side of the frame 20 and the piston rod moves through the long frame side of the frame 20 and then emerges from the top of the frame 20 to support the support ears 44 correspondingly arranged on the outer wall of the rectangular groove 42.

[0021] The supporting plate 10 is a rectangular plate and its length and width are the same as those of the frame 20. The supporting plate 10 is horizontally arranged directly below the frame 20 in the same length direction as the frame 20, and a vertical guide column 11 is provided on its long side. The vertical guide column 11 is movably inserted into the corresponding guide hole on the frame 20, thereby connecting the frame 20 to the supporting plate 10 for up and down movement.

[0022] The lifting cylinder 30 is uprightly arranged on the long side of the supporting plate 10 and the piston rod is fixedly connected to the long frame side of the surrounding frame, thereby lifting the surrounding frame 20 and connecting it to the supporting plate.

[0023] When the conveyor belt 60 transports the prefabricated quartz stone slabs to between the frame 20 and the supporting plate 10, the lifting cylinder 30 will drive the frame 20 to slowly descend and press on the supporting plate 10 and the conveyor belt 60. In order to reduce the downward resistance of the pressure head 40, the air in the closed chamber 70 needs to be evacuated before the pressure head 40 descends so that the closed chamber 70 forms a vacuum chamber. To this end, two air holes 21 that are connected inside and outside to connect the closed chamber 70 with the outside are arranged side by side near the bottom of the horizontal middle of the side wall of a long frame side of the frame 20. The outer opening of each air hole 21 is connected to an air pipe 22, and the outer end of each air pipe 22 is provided with an air distribution box 23. Each air distribution box 23 is provided with an exhaust pipe 24 for connecting to an exhaust pump. After the quartz stone slab is pressed into shape, the pressure head 40 can be driven upward to separate from the bottom surface of the frame 20 by the separation cylinder 50. At this time, high-pressure gas can be injected into the closed chamber 70 through the air pump, and then the lifting cylinder 30 can be used to lift the frame 20 away from the support plate 10 and the conveyor belt 60. This can help the lifting cylinder 30 lift the pressure head 40. For this purpose, the Meige air distribution box 23 is also provided with an air pipe 25 for connecting to the air pump.
