During the sliding process of the slider 10, the indicator needle 13 on its side will move along the scale line 9 to indicate the current cutting length. When the indicator needle 13 points to the preset cutting length position, the locking screw 11 is rotated and pressed against the top side of the main board 1, so that the slider 10 is fixed at this position. The telescopic rod 3 is controlled to be extended and retracted through the control panel 28, so that the action rod 4 drives the abutment plate 5 to move. During this process, the electrode plate 7 moves accordingly and gradually approaches the electrode sheet 12. When the abutment plate 5 moves to a certain position, the electrode plate 7 and the electrode sheet 12 contact each other, generate an electrical signal, and transmit the electrical signal to the control panel 28. The control panel 28 closes the telescopic rod 3. At this time, the distance between the cutter 16 and the abutment plate 5 is equal to the cutting length of the brick, realizing the preset cutting length, thereby being able to accurately control the cutting length of the brick, ensure the consistency of the brick size, and improve the paving effect of the road surface.

[0024] See also Figure 4As shown, a fixing frame 14 is fixedly installed at the middle end of the main board 1, and a cylinder 15 is installed on the top side of the fixing frame 14. A cutter 16 is fixed at the active end of the cylinder 15. A knife groove 17 is opened inside the main board 1, and the knife groove 17 is located directly below the cutter 16. During operation, in some newly developed areas, it is necessary to pave the road surface. Bricks are usually used for paving. Therefore, during the processing of bricks, a cutting device is needed to facilitate the paving of the road surface. When one end of the brick strip is in contact with the abutment plate 5, the cylinder 15 drives the cutter 16 to move downward. When the cutter 16 descends to contact with the brick, the cylinder 15 will apply a certain pressure to make the cutter 16 cut into the brick and penetrate into the knife groove 17. After the cutting is completed, the cylinder 15 will drive the cutter 16 to rise back to the initial position, take the brick, and the conveyor belt 25 will continue to convey the brick strip for the next cutting operation, thereby ensuring the stability and safety of the cutting process.

[0025] See also Figure 5 As shown, a fixing plate 18 is fixedly connected to the edge of the other end of the top side of the main board 1, a driving motor 19 is installed on one side of one end of the fixing plate 18, a bidirectional screw rod 20 is installed on the output end of the driving motor 19, one end of the bidirectional screw rod 20 passes through the main board 1 and is rotatably installed on one side inner wall of the fixing plate 18, a guide rod 21 is fixedly connected between the other ends of the fixing plate 18, and a limit plate 22 is installed on both ends of the guide rod 21 and the bidirectional screw rod 20;

A conveying motor 26 is installed on one side of the main board 1, and one end of the rotating roller 24 is matched and connected to the output end of the conveying motor 26;

[0027] Six support rollers 27 are fixedly installed between the grooves 23 at equal intervals, and the support rollers 27 are arranged in contact with the inner wall of the conveyor belt 25. The conveyor belt 25 and the main board 1 are on the same horizontal plane, and the limit plates 22 are respectively located above the two sides of the conveyor belt 25; when working, in the production process of bricks, brick strips are usually cut into required brick sizes. Therefore, in order to make the bricks continuous during processing, the brick strips to be cut are placed on the top side of the conveyor belt 25, and then the drive motor 19 is started to drive the bidirectional screw 20 to rotate at its output end, so that the limit plates 22 can move in opposite directions along the direction of the guide rod 21, so that the brick strips can be limited and conveyed, preventing the bricks from being offset and falling during the conveying process, thereby improving the processing accuracy of the bricks;

[0028] At the same time, the conveying motor 26 is started, and its output end drives the rotating roller 24 to rotate, so that the conveying belt 25 will perform a circular motion accordingly, so that the brick strips are conveyed in the direction of the cutter 16, thereby improving the working efficiency during brick processing.

[0029] Working principle: according to the required length of the brick, the slider 10 is slid into the slide groove 8 to the corresponding position. During the sliding process of the slider 10, the indicator needle 13 on the side thereof will move along the scale line 9 to indicate the current cutting length. When the indicator needle 13 points to the preset cutting length position, the locking screw 11 is rotated and pressed against the top side of the main board 1, thereby fixing the slider 10 at this position. The telescopic rod 3 is controlled to be extended and retracted through the control panel 28, so that the action rod 4 drives the abutment plate 5 to move. During this process, the electrode plate 7 moves accordingly and gradually approaches the electrode sheet 12. When the abutment plate 5 moves to a certain position, the electrode plate 7 and the electrode sheet 12 contact each other, generate an electrical signal, and transmit the electrical signal to the control panel 28. The control panel 28 closes the telescopic rod 3. At this time, the distance between the cutter 16 and the abutment plate 5 is equal to the cutting length of the brick, thereby realizing the preset cutting length, thereby being able to accurately control the cutting length of the brick, ensure the consistency of the brick size, and improve the paving effect of the road surface.

[0030] The brick strips to be cut are placed on the top side of the conveyor belt 25, and then the driving motor 19 is started, so that the output end of the driving motor 19 drives the bidirectional screw 20 to rotate, so that the limiting plate 22 can move in the direction of the guide rod 21 in the opposite direction or in the opposite direction, so that the brick strips can be limited and conveyed, and the displacement and falling of the bricks during the conveying process can be prevented, so as to improve the processing accuracy of the bricks;

[0031] At the same time, the conveying motor 26 is started, and its output end drives the rotating roller 24 to rotate, so that the conveying belt 25 will perform a circular motion accordingly, so that the brick strips are conveyed in the direction of the cutter 16, thereby improving the working efficiency during brick processing;

[0032] When one end of the brick strip fits against the abutment plate 5, the cylinder 15 drives the cutter 16 to move downward. When the cutter 16 descends to contact the brick, the cylinder 15 will apply a certain pressure to make the cutter 16 cut into the brick and penetrate into the knife groove 17. After the cutting is completed, the cylinder 15 will drive the cutter 16 to rise back to the initial position, take the brick away, and the conveyor belt 25 will continue to transport the brick strip for the next cutting operation, ensuring the stability and safety of the cutting process.
