DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1 -- Figure 3As shown, a construction material cutting device includes a placement table 4 at the upper end of a base 1 for placing construction materials that need to be cut, and the protective nets 3 on both sides of the support plate 2 at the upper end of the base 1 can protect the operator and reduce the safety hazards of cutting construction materials to the operator. The outer thread of the screw rod 15 is engaged with the inner thread of the screw hole 13 in the movable block 12. The motor 16 in the slide groove 14 at the upper end of the base 1 can drive the screw rod 15 connected at one end to rotate, thereby driving the movable block 12 to move its position, and then the placement table 4 at the upper end is driven to move its position through the connecting plate 11 and the electric push rod 10 at the upper end of the movable block 12, so as to transport the construction materials on the placement table 4 to the lower end of the cutting knife 20, and the placement is adjusted by adjusting the height of the electric push rod 10. The height of the platform 4 is adjusted, and the motor 16 can rotate in the opposite direction to transport the construction materials on the placement platform 4 out from the lower end of the cutting knife 20. Automatic loading and unloading can reduce the dependence on operators, while saving manual operation time and greatly improving production efficiency, especially next to high-speed cutting equipment, avoiding the risk of manual operation being injured by the tool. The upper end of the placement platform 4 adopts a frosted surface, which can increase the stability of the placement of construction materials and reduce the sliding of construction materials during cutting. The lower end of the L-shaped frame 5 at the upper end of the base 1 and the limit block 8 are both located in the limit groove 9. After the limit block 8 is pulled out of the limit groove 9, the L-shaped frame 5 can be moved. A circular ring 6 is connected in the middle of the two sets of relatively arranged L-shaped frames 5, and a limit ring groove 7 is provided on the inner side of the circular ring 6.

[0025] like Figure 4 As shown, a polygonal groove 19 which can be matched with the polygonal limiting column 21 is provided on one side of the mounting block 18 and the movable column 22. The polygonal limiting columns 21 installed on both sides of the cutting knife 20 are both located in the polygonal groove 19. The motor 17 at one end of the support plate 2 can drive the mounting block 18 installed at one end to rotate, thereby driving the cutting knife 20 to rotate. The polygonal limiting column 21 on one side of the cutting knife 20 drives the movable column 22 to rotate by matching with the polygonal groove 19. The limiting ring 23 on the outer side of the movable column 22 rotates in the circular ring 6 by matching with the limiting ring groove 7. The movable column 22 is removed, and the cutting knife 20 is separated from the mounting block 18. The cutting knife 20 can be quickly replaced without the need for additional disassembly tools. The operation process of replacing the cutting knife 20 is simplified, the complexity of manual operation is reduced, and the labor cost required for replacing the tool is reduced, so that personnel can complete the tool replacement work faster.

[0026] Working principle: The placement table 4 at the top of the base 1 is used to place the construction materials that need to be cut. The protective nets 3 on both sides of the support plate 2 at the top of the base 1 can protect the operator. The motor 16 in the slide 14 at the top of the base 1 can drive the screw 15 connected at one end to rotate, thereby driving the movable block 12 to move its position, and then the connection plate 11 and the electric push rod 10 at the top of the movable block 12 drive the placement table 4 at the top to move its position, transport the construction materials on the placement table 4 to the lower end of the cutting knife 20, and adjust the height of the placement table 4 by adjusting the height of the electric push rod 10. The construction materials on the placement table 4 can be moved by rotating the motor 16 in the opposite direction. The material is transported out from the lower end of the cutting knife 20, and the motor 17 can drive the mounting block 18 installed at one end to rotate, thereby driving the cutting knife 20 to rotate. The polygonal limiting column 21 on one side of the cutting knife 20 drives the movable column 22 to rotate by fitting with the polygonal groove 19, and the limiting ring 23 on the outer side of the movable column 22 rotates in the circular ring 6 by fitting with the limiting ring groove 7, thereby maintaining the stability of the cutting knife 20. After the limiting block 8 is pulled out of the limiting groove 9, the L-shaped frame 5 can move its position, thereby driving the internal movable column 22 to move its position. When the movable column 22 is removed, the cutting knife 20 is separated from the mounting block 18, and the cutting knife 20 can be quickly replaced.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
