Description

Technical Field

[0001] The present invention relates to the technical field of building board cutting, and in particular to a cutting device for lightweight and environmentally friendly building boards. Background Art

[0002] Lightweight, environmentally friendly building panels are a new type of building material, characterized by their lightweight and environmentally friendly properties. They are widely used in modern buildings for interior partitions, ceilings, exterior wall insulation, and decoration. By optimizing material formulation and structural design, they significantly reduce their weight and environmental impact while maintaining mechanical properties, aligning with the trends of green building and sustainable development.

[0003] At present, all lightweight and environmentally friendly building panels are prefabricated, that is, they are pre-made into certain specifications and shapes. However, due to different architectural designs, they need to be cut into the required shape or length when used, and this cutting is generally carried out on-site. The cutting machine currently used performs vertical cutting, and the incision is vertical. This results in that after cutting any of the four sides of the panel, the prefabricated concave and convex matching structures or staggered structures on the four sides of the panel will also be cut off simultaneously. However, since the incision is vertical, there is no staggered effect between the cut surface of the panel and the contact surface of other panels. It is only fixed by cement mortar, which affects the integrity of the panel laying and may cause the supporting strength of the position to decrease. If the strength is to be maintained, a manual handheld cutting machine is required to cut out the concave and convex or staggered structures, which in turn reduces the efficiency of on-site modification of the panel and increases the amount of extra work. Summary of the Invention

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A cutting device for lightweight environmentally friendly building panels, comprising a machine platform, a circular saw blade for cutting mounted on the front side of the machine platform, and a motor for driving the circular saw blade to rotate mounted on the machine platform; A support platform is installed under the machine, and the machine is rotated based on the support platform; The rotation of the machine table drives the circular saw blade to rotate in the front and back directions based on the machine table.

[0005] Furthermore, a spindle is fixed to the front bottom of the machine, on which a spindle is mounted, and the circular saw blade is fixedly mounted to the spindle. The spindle is mounted relative to the front bottom of the machine via the spindle, which reduces the spindle's effect on the cutting depth of the circular saw blade. The larger motor is also positioned above the circular saw blade, leaving sufficient space for cutting at the bottom of the circular saw blade, thereby maximizing the use of the circular saw blade's diameter.

[0006] Furthermore, the support platform and the front side of the machine are hingedly connected via a first hinge seat, allowing the machine to rotate forward and backward about the first hinge seat. A telescopic rod is hingedly mounted between the support platform and the rear side of the machine. The first hinge seat not only provides hinged support for the machine but also acts as a limiter, restricting the machine to forward and backward rotation and preventing rotation in other directions.

[0007] Furthermore, two sets of wheel frames are fixed to the bottom of the support platform, and the bottoms of both sets of wheel frames are equipped with moving wheels. The moving wheels facilitate the movement of the support platform and the machine. At the same time, the machine is positioned relative to the upper part of the circular saw blade, leaving sufficient space below for the installation of the moving wheels, and the impact on the cutting depth is limited.

[0008] Furthermore, a support frame is placed below the moving wheel, and the moving wheel is supported by the support frame. The support frame extends the support surface of the moving wheel, so that the circular saw blade can completely cut the entire plate at one time. To avoid excessive extension and resulting in a shift in the center of gravity, it is necessary to control the extension length, or use manpower in the opposite direction or heavy objects for counterweighting.

[0009] Furthermore, a track bar is mounted on the top of the support frame, a middle spacer bar is fixed in the middle of the top of the track bar, and a positioning ring is fixed in the middle of the moving wheel. The cross-section of the positioning ring is a U-shaped structure that cooperates with the middle spacer bar. The positioning ring cooperates with the middle spacer bar to further ensure the straight-line effect of the moving wheel when it moves, based on the lack of steering of the moving wheel. It is particularly suitable for long straight-line cutting. When steering is required, it can be achieved by manual movement. Of course, it is also possible to install a motor on the moving wheel and control the motor to achieve controlled steering. These are all foreseeable replacement or conventional improvement solutions.

[0010] Furthermore, a plurality of anti-skid bumps are fixed to the rolling support surface of the moving wheels, thereby increasing the direction of friction to ensure the stable rotation of all the moving wheels, thereby ensuring smooth, stable and reliable movement.

[0011] Furthermore, the circular saw blade is configured to rotate clockwise. A water tank is mounted on the left side of the top of the machine. A water pipe is fixed to the bottom of the left front end of the water tank. The end of the water pipe is angled downward, close to the left teeth of the circular saw blade. As the circular saw blade rotates clockwise, the water pipe moistens cutting dust and debris from the left side of the saw blade, thereby reducing dust. This makes it suitable for cutting fiber cement or lightweight concrete panels with high dust content, but should not be used on panels that are not suitable for contact with water.

[0012] Furthermore, a second water tank is mounted on the right side of the top of the machine, and a second water pipe is fixed to the bottom of the right front end of the second water tank. The ends of the second water pipe are angled downward, close to the right teeth of the circular saw blade. The second water pipe can rinse and cool the teeth about to cut. When used in conjunction with the first water pipe, it comprehensively ensures the stability of the circular saw blade during cutting and provides dust protection. At the same time, because the first and second water pipes are arranged to the left and right of the circular saw blade, the circular saw blade does not need to be restricted to clockwise rotation, and can freely rotate clockwise or counterclockwise, or switch between the two directions.

[0013] Furthermore, the outlets of the first and second water supply pipes are respectively directed to the left and right teeth of the circular saw blade from the left and right directions. Directly directed to the teeth, the water flow can ensure the flushing effect on the teeth, and the debris in the teeth can be cleaned as much as possible, so as to ensure that the teeth have sufficient cutting force on the plate.

[0014] The beneficial effects of the present invention are as follows: 1. This invention utilizes a rotatable machine platform, which in turn rotates the circular saw blade. This allows the blade to be adjusted vertically or tilted. When tilted, the saw blade achieves a beveled cut. The beveled surfaces of two sheets can be combined to create a staggered seam, allowing for a single cut without the need for manual modification.

[0015] 2. The present invention is provided with moving wheels, which can be easily moved, convenient for transportation and use, and can improve the straight-line cutting effect when in use.

[0016] 3. The present invention uses a support frame to provide additional support, which can be extended when cutting the plate, so that the entire plate can be completely cut at one time, and the operator does not need to hold the machine hand, which is convenient for operation.

[0017] 4. The present invention provides a water tank and a water pipe to flush the left and right teeth of the circular saw blade, achieving the purpose of flushing and cooling, thereby ensuring the continuous, stable and reliable cutting effect of the circular saw blade.
