[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 As shown, a foam board cutting device includes a workbench 1. The foam board to be cut is placed on the upper surface of the workbench 1. A moving rod 2 is horizontally slidably arranged below the workbench 1. The moving rod 2 is horizontally arranged, and a blocking rod 3 is vertically arranged at one end of the moving rod 2. The blocking rod 3 is located on one side of the workbench 1 and is used to block the foam board. The upper end of the blocking rod 3 extends to the top of the workbench 1. A cutting frame 4 is vertically slidably arranged at one end of the workbench 1 near the blocking rod 3. The cutting frame 4 has a "door" shaped structure. The vertical rods on both sides of the cutting frame 4 are slidably connected to the workbench 1. A cutting wire 5 is horizontally arranged on the cutting frame 4. The cutting wire 5 is an electric heating wire. The cutting wire 5 is heated by electric heating. The cutting wire 5 and the cutting frame 4 are fixedly connected by an insulating fixing block.

[0027] In this invention, the foam board to be cut is laid flat on the upper surface of the workbench 1. The distance between the cutting wire 5 and the blocking rod 3 is adjusted by sliding the moving rod 2. The distance between the cutting wire 5 and the blocking rod 3 is the cutting size of the foam board. After adjustment, the foam board is slid to one side of the blocking rod 3 so that one end of the foam board abuts against the blocking rod 3. The blocking rod 3 limits the foam board. The cutting frame 4 slides down, causing the cutting wire 5 to slide down. Since the cutting wire 5 is an electric heating wire, it is heated after being energized, which can cut the foam board. Therefore, the cutting wire 5 can cut the foam board during the sliding process, so that the foam board is cut into a fixed size. The cutting size is more accurate, thereby improving the cutting accuracy. In addition, during the cutting process, the foam boards to be cut can be stacked together for cutting, cutting multiple foam boards at once, thereby speeding up the cutting speed and improving the cutting efficiency.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, the workbench 1 includes a tabletop 6 and a frame 7 fixedly installed at the bottom of the tabletop 6. The frame 7 supports the tabletop 6. The movable rod 2 is slidably mounted on the frame 7 and is located below the tabletop 6. A locking assembly is provided between the movable rod 2 and the frame 7 to lock the movable rod 2 and the frame 7 together, preventing the movable rod 2 from shifting when the foam board hits the blocking rod 3. The locking assembly includes a locking rod 8 and a support frame 9. The lower end of the locking rod 8 is rotatably mounted on the frame 7, and the locking rod 8 is located below the movable rod 2. On one side, a locking block 10 is provided on the locking rod 8. One end of the locking block 10 is rotatably connected to the locking rod 8. The end of the locking block 10 away from the locking rod 8 is a free end. The locking block 10 is a wedge-shaped block. The thickness of the side of the locking block 10 away from the locking rod 8 is less than the thickness of the side closer to the locking rod 8. The locking block 10 is located above the moving rod 2. The support frame 9 is fixedly installed on the frame 7. A locking plate 11 is fixedly installed at the top of the support frame 9. The locking plate 11 is horizontally installed and located above the locking block 10. In this embodiment, when the moving rod 2 needs to be locked after moving a certain distance, the locking rod 8 is rotated to one side of the moving rod 2, so that the locking block 10 is inserted between the locking plate 11 and the moving rod 2. Since the locking block 10 is a wedge-shaped structure, it can continuously fill the gap between the locking plate 11 and the moving rod 2 during the insertion process. Finally, the upper end face of the locking block 10 is tightly fitted with the locking plate 11, and the lower end face of the locking block 10 is tightly fitted with the moving rod 2. As is well known, the wedge-shaped block has a self-locking function. Due to the friction, the moving rod 2 is locked and fixed, so that the position of the moving rod 2 will not move when the foam board collides with the blocking rod 2, making the cutting accuracy more precise. When the position of the moving rod 2 needs to be adjusted, the locking rod 8 is rotated to the side away from the moving rod 2, and the locking block 10 is moved out of the gap between the locking plate 11 and the moving rod 2.

[0029] Furthermore, a lower support block is fixedly provided on the upper end face of the locking block 10, and the upper end face of the lower support block is provided with an arc-shaped protrusion. An upper support block is fixedly provided on the lower end face of the locking plate 11, and the lower end face of the upper support block is an arc-shaped recess. The protrusion of the lower support block and the recess of the upper support block cooperate with each other. When the locking block 10 locks the moving rod 2, it can cause the locking block 10 to rotate at a certain angle, thereby locking and fixing the moving rod 2.

[0030] Furthermore, a pressure rod 12 is fixedly installed at the upper end of the locking rod 8. The pressure rod 12 is horizontally positioned, and a spring 13 is connected between the pressure rod 12 and the top of the frame 2. The two ends of the spring 13 are fixedly connected to the top of the frame 2 and the pressure rod 12, respectively. When locking the moving rod 2, the pressure rod 12 is pressed down to rotate the locking rod 8 towards the side closer to the moving rod 2, so that the locking block 10 is inserted into the gap between the moving rod 2 and the locking plate 11. Conversely, when the moving rod 2 needs to move, the pressure rod 12 is lifted up to rotate the locking rod 8 away from the moving rod 2, so that the locking block 10 is moved out of the gap between the moving rod 2 and the locking plate 11.

[0031] Furthermore, the end of the movable rod 2 away from the blocking rod 3 is provided with a connecting rod 14. The connecting rod 14 is horizontally arranged and perpendicular to the movable rod 2. The two ends of the connecting rod 14 are respectively rotatably provided with first limiting rollers 15. The two first limiting rollers 15 roll in contact with the two sides of the frame 2 respectively, thus limiting the movable rod 2 and preventing the movable rod 2 from swaying left and right during movement.

[0032] Furthermore, a second limiting roller 16 is rotatably mounted on the frame 7. One side of the moving rod 2 slides in contact with the support frame 9, and the other side rolls in contact with the second limiting roller 16. The moving rod 2 is clamped by the support frame 9 and the second limiting roller 16 to further prevent the moving rod 2 from swaying left and right. At the same time, the first limiting roller 15 and the second limiting roller 16 roll in contact with the moving rod 2, making the moving rod 2 move more smoothly and steadily.

[0033] Furthermore, a support roller 17 is rotatably mounted on the frame 7. The support roller 17 is located between the second limiting roller 16 and the support frame 9. The support roller 17 makes rolling contact with the bottom of the moving rod 2, making the moving rod 2 more stable during movement.

[0034] Furthermore, a handle 18 is fixedly provided on the cutting frame 4. The handle 18 is convenient for the operator to hold and for the cutting frame 4 to slide up and down to cut the foam board.

[0035] Furthermore, a fixing rod 19 is fixedly installed at one end of the workbench 1. The fixing rod 19 is fixedly connected to the frame 7. The fixing rod 19 is vertically arranged, and two fixing rods 19 are arranged in parallel. A sliding groove 20 is opened on the fixing rod 19. The vertical rods on both sides of the cutting frame 4 are slidably arranged in the sliding groove 20 of the fixing rod 19, which can limit the cutting frame 4 and make the cutting frame 4 slide in the vertical direction so as to cut the foam board.

[0036] Furthermore, an upper limit rod 21 and a lower limit rod 22 are fixedly installed on the side wall of the fixing rod 19. The upper limit rod 21 is located above the lower limit rod 22 and is also located above the table surface 6. The lower limit rod 22 is located below the table surface 6 or is set horizontally with the table surface 6. A support rod 23 is rotatably installed on the cutting frame 4. The support rod 23 can rotate in the horizontal direction and is supported on the upper limit rod 21 or the lower limit rod 22. In this embodiment, during the adjustment of the moving rod 2 and the movement of the foam board, the cutting frame 4 is slid upward so that the support rod 23 is above the upper limit rod 21. The support rod 23 is rotated so that it rests on the upper limit rod 21, which can support the cutting frame 4 and prevent it from falling. When cutting the foam board, the support rod 23 is rotated so that it is disengaged from the upper limit rod 21. Under the action of gravity or by the operator holding the handle 18, the cutting frame 4 is slid downward to cut the foam board. When the support rod 23 moves below the upper limit rod 21, the support rod 23 is rotated so that it is directly above the lower limit rod 22. As the cutting frame 4 continues to slide down, the support rod 23 rests on the lower limit rod 22, which limits the cutting frame 4 and prevents it from continuing to slide down.

[0037] Furthermore, a positioning plate 24 is vertically arranged on the upper surface of the workbench 1, and one side of the foam board abuts against the positioning plate 24. When multiple foam boards are stacked together, in order to facilitate the arrangement of the foam boards and make them more neat, one side of the foam board can be made to fit against the positioning plate 24.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
