[0002] In the fields of wood processing, building materials production, and furniture manufacturing, board cutting is a fundamental and frequently performed processing step. Although traditional board cutting devices have a protective cover above the circular saw blade, there is usually a gap between the protective cover and the device table for the board to pass through. When feeding or adjusting the position of the board, the operator's fingers can easily slip through this gap and accidentally enter the saw blade area, posing a high risk. Furthermore, debris generated during the cutting process can fly outwards from the gap between the protective cover and the board, resulting in poor protection.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0019] Please see Figure 1-3 A cutting device for processing sheet metal with protective effect includes a frame 1, a table 2 mounted on the frame 1, a strip-shaped through hole on the table 2, a cutting blade structure mounted on the frame 1, the cutting blade structure passing through the strip-shaped through hole, and a protective structure mounted on the table 2.

[0020] It should be noted that the device is placed at the target location via rack 1 and connected to a power source;

[0021] Specifically, the protective structure includes a column 3, which is installed on the upper wall of the tabletop 2. A crossbar 4 is installed at one end of the column 3. An electric push rod 5 is installed on the lower wall of the crossbar 4. A bracket 6 is installed at the telescopic end of the electric push rod 5. A spring column 7 is installed on the lower wall of the bracket 6. A buckle 8 is installed at one end of the spring column 7. The buckle 8 includes a U-shaped plate 81. An arc-shaped cover 82 is provided at the center of the U-shaped plate 81. A U-shaped upright plate 83 is provided at the edge of the U-shaped plate 81. Multiple short shafts 9 are movably inserted on both sides of the U-shaped upright plate 83. Narrow wheels 10 are fixedly fitted on each of the multiple short shafts 9. Long shafts 11 are movably inserted on both sides of the U-shaped upright plate 83 and at both ends of the multiple short shafts 9. Wide wheels 12 are fixedly fitted on the long shafts 11. Two limiting components are symmetrically installed on the tabletop 2 with the cutter structure as the center.

[0022] It should be noted that when the electric push rod 5 extends to its limit position, the narrow wheel 10 and the wide wheel 12 are in contact with the table surface 2, and the spring column 7 is in its natural state. The U-shaped plate 81, the arc-shaped cover 82, and the U-shaped upright plate 83 are integrated into a cover 8, which is made of transparent plastic material, making it easy for workers to observe the working situation between the cutting structure and the board. The initial state is that the electric push rod 5 is retracted to its limit position, placing the board on the table surface 2. By adjusting the two limiting components, the two sides of the board are clamped and limited, so that the part of the board to be cut is aligned with the cutting structure. Then, the electric push rod 5 is controlled to extend to its limit position, and the narrow wheel 10 and the wide wheel 12 are in contact with the upper wall of the board. At this time, the spring column 7 is in a compressed state, and the compression of the spring column 7 can... To enable the device to be used with boards of different thicknesses, pressure is applied to the longitudinal direction of the board, and the cover 8 is fastened to the cutting structure. At the same time, the narrow wheel 10 and the wide wheel 12 also cover the gap between the cover 8 and the board, preventing the operator's hands from approaching the cutting structure and preventing board debris from flying and causing injury to the operator. When cutting the board, the cutting structure works, and the operator pushes the board between the two limiting components. The board moves on the table 2, and the cutting structure cuts the board. Under the friction between the narrow wheel 10 and the wide wheel 12 and the board, the board moves and drives the narrow wheel 10 and the short shaft 9 to rotate, and drives the wide wheel 12 and the long shaft 11 to rotate, eliminating the friction between the board and the cover 8.

[0023] Specifically, each limiting component includes a connecting plate 13, which is movably fitted onto the table 2. The connecting plate 13 has an elongated hole, and an external threaded post 14 is installed on the table 2. The connecting plate 13 is movably fitted onto the external threaded post 14 through the elongated hole. A longitudinal baffle 15 is installed at one end of the connecting plate 13, and a wing nut 16 is movably fitted onto the external threaded post 14 through the thread.

[0024] It should be noted that by moving the connecting plate 13 laterally along the elongated hole, the longitudinal baffle 15 is made to fit against the edge of the plate. By tightening the wing nut 16 on the external threaded post 14, the connecting plate 13 is fixed on the table 2 for limiting and guiding the edge of the plate.

[0025] Specifically, the cutting structure includes a motor 17, which is mounted on the frame 1. The drive end of the motor 17 is equipped with a drive pulley 18. A rotating shaft 20 is mounted on the frame 1 via a bearing seat 19. A driven pulley 21 is fixedly mounted on the rotating shaft 20. A belt 22 is movably mounted on the drive pulley 18 and the driven pulley 21. A circular saw blade 23 is fixedly mounted on one end of the rotating shaft 20. The circular saw blade 23 movably passes through the strip-shaped through hole.

[0026] It should be noted that the motor 17 drives the drive pulley 18 to work, and through the cooperation of the belt 22, the drive pulley 18 and the driven pulley 21, the rotating shaft 20 rotates on the bearing seat 19, and the circular saw blade 23 rotates to cut the plate.

[0027] As a preferred and further option, a guide rod 24 is movably inserted into the crossbar 4. The guide rod 24 is installed on the upper wall of the bracket 6 and is used to guide and limit the lifting and lowering of the bracket 6 and to protect the telescopic end of the electric push rod 5.

[0028] Preferably, the number of spring posts 7 is at least 2, and the number of connecting plates 13 is 2;

[0029] As a preferred and further option, a control panel 25 is installed on the tabletop 2; the control panel 25 has a built-in microcontroller that can be programmed into software, and the control program is written to control the device. Since this is existing technology, it will not be described in detail here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
