Description

Technical Field

[0002] Foamed ceramic insulation board is a closed-cell ceramic material with high porosity, made of clay tailings, ceramic fragments, river silt, adulterated materials, etc. as the main raw materials, using advanced production technology and foaming technology and high-temperature roasting.

[0003] The foamed ceramic composite board is composed of two layers of foamed ceramic boards and polystyrene particle concrete between the two layers of foamed ceramic boards. In the production process of the foamed ceramic composite board, a plurality of foamed ceramic composite boards are usually placed in a mold for casting. A partition is arranged between adjacent foamed ceramic composite boards. After the foamed ceramic composite board is cast, the vertical partition needs to be separated from the foamed ceramic composite board. Since the two are bonded to each other, the surface of the foamed ceramic composite board is uneven after separation, which seriously affects the quality of the foamed ceramic composite board. In order to overcome the above-mentioned shortcomings, no partition is arranged in the mold, and adjacent foamed ceramic composite boards share a foamed ceramic board twice as thick in the mold. After casting, they are cut. In this way, the surface of the cut foamed ceramic composite board is no longer uneven, and the quality is significantly improved. The foamed ceramic composite board cast in the same mold is as follows: Figure 7 As shown, two adjacent foamed ceramic composite panels need to be cut. Currently, there are only cutting machines for single foamed ceramic panels, which are not suitable for the foamed ceramic composite panels made in the above manner. At the same time, the existing cutting machines have single functions. After the foamed ceramic composite panels are cast and formed, they need to go through multiple processes to be made into finished products. Not only is the production efficiency low, but also due to the large mass and volume of the foamed ceramic composite panels, it is time-consuming and labor-intensive to transport them, and they are prone to chipping after collision.

The ceramic conveyor line 1 adopts a crawler conveyor line. Limit blocks (not shown in the figure) for limiting the position of the foamed ceramic composite board are arranged on the left and right sides of each ceramic conveyor line 1. Several ceramic conveyor lines 1 are arranged in sequence from front to back, and the conveying direction is from front to back. The end edge grinding mechanism, the groover 2 and the cutting machine 3 are respectively arranged between two adjacent ceramic conveyor lines 1, and are arranged in sequence from front to back. The ceramic conveyor line 1 conveys the foamed ceramic composite board to the end edge grinding mechanism, the groover 2 and the cutting machine 3 in sequence, thereby realizing the end edge grinding processing, upper and lower side grooves and cutting of the foamed ceramic composite board, and finally forming a single piece of foamed ceramic composite board finished product.

[0025] like Figure 2As shown, the end edge grinding mechanism includes an edge grinding conveyor line 4, a slide rail 6 and two end edge grinding machines 5. The two end edge grinding machines 5 are arranged front and back relative to each other and are located on the same side of the ceramic conveyor line 1. The two end edge grinding machines 5 move forward and backward respectively under the drive of the corresponding screw slide 504.

In this embodiment, the edge grinding wheel adopts a wear-resistant and sharp diamond edge grinding wheel. The edge grinding wheel includes an edge grinding disc 501 extending forward and backward along the axis. A circle of edge grinding protrusions 502 arranged at intervals and distributed in a circumferential array are arranged on the disc surface of the edge grinding disc 501 close to the slide rail 6. The edge grinding disc 501 can be rotated respectively under the drive of each motor 503. A spray pipe 505 is also provided on the end edge grinding machine 5, and the nozzles of the spray pipe 505 are all oriented toward the contact surface between each edge grinding protrusion 502 and the foamed ceramic composite board. The two slide rails 6 are spaced apart front to back and extend left to right. One end of the two slide rails 6 is located between the front and rear ceramic conveyor lines 1, and the other end is located between the two end edge grinding machines 5. The edge grinding conveyor line 4 adopts a crawler conveyor line extending front to back. The edge grinding conveyor line 4 is installed on the sliding sleeves of the two slide rails 6. The edge grinding drive motor 7 drives the edge grinding conveyor line 4 to slide left and right along the two slide rails 6 through a sprocket chain mechanism. The ceramic conveyor line 1 on the front side conveys the foamed ceramic composite board to the edge grinding conveyor line 4, and the edge grinding conveyor line 4 slides along the two slide rails 6 to between the two end edge grinding machines 5 under the drive of the edge grinding drive motor 7. During the sliding process, the two end edge grinding machines 5 are respectively driven by the corresponding screw slides 504 to move toward the direction close to the edge grinding conveyor line 4, and the edge grinding discs 501 rotate under the drive of their respective motors 503 to grind the front and back ends of the foamed ceramic composite board on the edge grinding conveyor line 4. After the edge grinding is completed, the motor 503 stops driving the edge grinding disc 501, and the two end edge grinding machines 5 are respectively driven by the corresponding screw slides 504 to move away from the edge grinding conveyor line 4. The edge grinding conveyor line 4 slides along the two slide rails 6 to between the front and rear ceramic conveyor lines 1 under the drive of the edge grinding drive motor 7, and the edge grinding conveyor line 4 then conveys the foamed ceramic composite board to the ceramic conveyor line 1 on the rear side.

The distance between the middle cross sections of two adjacent cutting saw blade groups 203 is equal to the thickness of a single foamed ceramic composite board. Therefore, the cutting roller 201 and the grooving roller 202 can groove at the same position on the upper side of each foamed ceramic composite board and form a protrusion at the same position on the lower side. When installing the foamed ceramic composite board, the groove on the upper side and the protrusion on the lower side are embedded, which greatly increases the stability of the installation structure of the foamed ceramic composite board and makes the installation more convenient and the installation position accurate.

The anti-wear sheet 307 is installed on the anti-wear sheet fixing plate 308 by bolts, and the gap width between the anti-wear sheets 307 on both sides is smaller than the width of the notch 308a, and the cutting section of the saw blade 303 passes through the corresponding gap and notch 308a respectively.

[0029] Furthermore, a tensioning mechanism is also provided on the "mouth"-shaped frame 309, and the tensioning mechanism includes a hydraulic cylinder 304 and a U-shaped fixing frame 305.
