[0029] Please see Figure 1-Figure 5 This utility model provides a cutting machine, including an operating table 100. Two connecting plates 104 are arranged above the operating table 100. Rotating shafts 200 are movably connected to one side of the two connecting plates 104, which are close to each other. A C-shaped frame 201 is fixed between the two rotating shafts 200, which are close to each other. A cutting blade 207 is arranged below the C-shaped frame 201. A rack 403 is fixed to the top of one side of one of the connecting plates 104. Four circumferentially distributed engaging grooves 402 are opened on the outer wall of one side of the rotating shaft 200. A gear 400 is arranged on the outer wall of one side of the rotating shaft 200. The gear 400 meshes with the rack 403. Four engaging blocks 401 are fixed on the inner wall of the gear 400. The engaging blocks 401 are correspondingly and movably engaged in the engaging grooves 402.

[0030] Further as Figure 1As shown, a top opening 202 is provided in the middle of the top surface of the C-shaped frame 201. A cylinder 203 is fixed to the inner side wall of the top opening 202. A second T-shaped groove 204 is provided on one side of the inner side wall of the C-shaped frame 201. A second T-shaped block 205 is movably engaged in the second T-shaped groove 204. A connecting post 206 is fixed to the bottom surface of the second T-shaped block 205. The bottom end of the connecting post 206 is fixed to the top surface of the cutting blade 207. The bottom of the connecting post 206 moves through the bottom of the C-shaped frame 201. A connecting strip 208 is fixed between the two second T-shaped blocks 205 on one side.

[0031] The second T-slot 204 and the second T-block 205 allow the position of the connecting strip 208 to be movably limited, and the connecting post 206 allows the cutting blade 207 to be connected to the connecting post 206.

[0032] Further as Figure 3 As shown, a docking post 300 is fixed in the middle of the top surface of the connecting strip 208. The outer wall of the docking post 300 has four circumferentially distributed side grooves 301. The bottom of the outer wall of the cylinder 203 output end has four circumferentially distributed locking rods 302. One end of the locking rod 302 is correspondingly locked in the side groove 301. A pressure sensor 303 is fixed on the bottom surface of the cylinder 203 output end.

[0033] The side groove 301 and the locking rod 302 enable the docking post 300 to connect with the output end of the cylinder 203. The pressure sensor 303 enables the output end of the cylinder 203 to push the connecting bar 208 so that the cutting blade 207 can cut the expanded polystyrene on the top surface of the operating table 100. The pressure sensor 303 can obtain the pushing pressure value of the cylinder 203, thereby avoiding excessive thrust of the cylinder 203, which could cause excessive contact between the cutting blade 207 and the top surface of the operating table 100, and damage to the cutting blade 207.

[0034] This solution includes the following working process: When vertically cutting expanded polystyrene (EPS) boards, the EPS board is first placed on the top surface of the operating table 100. To cut the EPS board vertically, the L-shaped plate 103 on one side is pushed, causing the cutting blade 207 to move to the desired cutting position. Then, the PLC controller 801 is operated, controlling the cylinder 203 to start. The output end of the cylinder 203 moves, driving the connecting bar 208 to move. The movement of the connecting bar 208 drives the second T-shaped blocks 205 on both sides to move, which in turn drives the cutting blade 207 to move until it contacts the surface of the EPS board. Then, the output end of the cylinder 203 continues to move downwards, causing the pressure sensor 303 to move downwards. The downward movement of the pressure sensor 303 pushes the docking post 300 downwards, and the movement of the docking post 300 drives the cutting blade 207 to move, ultimately causing the cutting blade 207 to vertically cut the EPS board. In the direction of cutting, when the cutting blade 207 is cutting the expanded polystyrene board, the pressure sensor 303 monitors the received pressure value in real time and transmits the signal to the PLC controller 801. The PLC controller 801 compares the received pressure signal with the preset pressure value stored in its internal memory in real time. When the cutting blade 207 has completely cut the expanded polystyrene board, the pressure value monitored by the pressure sensor 303 exceeds the preset pressure value stored in the PLC controller 801. At this time, the PLC controller 801 receives the pressure signal sent by the pressure sensor 303 and compares it with the preset pressure value. If the received pressure is greater than or equal to the preset pressure value, the PLC controller 801 controls the output end of the cylinder 203 to move upward and reset. Then, the L-shaped plate 103 can be pushed so that the cutting blade 207 moves to the next position to be cut. By repeating the above operation, the expanded polystyrene board can be cut at different positions.

[0035] When performing a beveled cut on expanded polystyrene (EPS) board, first, manually pull the rotating ring 601. The movement of the rotating ring 601 drives the gear 400 to move until the gear 400 separates from the rack 403. During this process, the movable disk 502 moves and compresses the spring 501. Then, rotate the rotating ring 601, causing the rotating shaft 200 on that side to rotate. The rotation of the rotating shaft 200 drives the C-shaped frame 201 to rotate. At this time, the cutting blade 207 tilts. While rotating the rotating ring 601, the pointer 701 and the scale 70 can be observed. The pointer 701 is positioned relative to the dial 700 at the corresponding angle. Then, the rotating ring 601 is slowly released, and the spring 501 releases its elastic force to push the movable disk 502. The movable disk 502 pushes the gear 400, so that the gear 400 and the rack 403 are tightly meshed. At this time, the angle of the cutting blade 207 is the angle required for cutting. Then, the polystyrene board can be tilted according to the operation of vertical cutting of polystyrene board. At this time, the polystyrene board can be cut at an angle.

[0036] As can be seen from the above working process: the pointer 701 and the dial 700 allow the angle of inclination of the cutting blade 207 to be observed, thus facilitating the control of the angle of inclination of the cutting blade 207; the engaging block 401 and the engaging groove 402 allow the gear 400 to separate from and engage with the rack 403; the movable disc 502 and the spring 501 allow the gear 400 to mesh tightly with the rack 403; and the cutting blade 207 and the cylinder 203 enable the expanded polystyrene board to be cut vertically and at an angle, thus improving the applicability of the cutting machine.

[0037] By using the pressure sensor 303 and PLC controller 801, the push applied by the cylinder 203 can be monitored, thereby preventing the excessive thrust of the cylinder 203 from causing excessive contact force between the cutting blade 207 and the operating table 100, which could damage the cutting edge of the cutting blade 207.

[0038] Further as Figure 4 As shown, a locking disc 500 is fixed to one side of the outer wall of the rotating shaft 200 on one side, a movable disc 502 is movably connected to the outer wall of the rotating shaft 200 on one side, and a spring 501 is provided on the outer wall of the rotating shaft 200 on one side. One end of the spring 501 is fixed to one side of the movable disc 502, and the other end of the spring 501 is fixed to one side of the locking disc 500. Four circumferentially distributed fixing posts 600 are fixed to one side of the gear 400, and a rotating ring 601 is fixed to one end of each of the four fixing posts 600.

[0039] The spring 501 and the movable disc 502 ensure that the gear 400 can stably mesh with the rack 403, preventing the gear 400 from moving on the rotating shaft 200 on one side and causing the gear 400 to separate from the rack 403.

[0040] Further as Figure 4 As shown, a dial 700 is fixed to the bottom of one side of the connecting plate 104, and a pointer 701 is fixed to the bottom of one side of the gear 400. The pointer 701 cooperates with the dial 700.

[0041] The angle of inclination of the cutting blade 207 can be observed by the dial 700 and pointer 701, which makes it easier to tilt the cutting blade 207.

[0042] The scale on dial 700 is 0-180 degrees.

[0043] Further as Figure 1 and Figure 4As shown, the top surface of the operating table 100 is provided with a first T-shaped groove 101 on both sides, a first T-shaped block 102 is movably engaged in the first T-shaped groove 101, an L-shaped plate 103 is fixed on the top surface of the first T-shaped block 102, one end of the L-shaped plate 103 is fixed to one side of the corresponding connecting plate 104, and a stop strip 800 is fixed on both sides of the top surface of the operating table 100.

[0044] By setting the first T-slot 101 and the first T-block 102, the connecting plate 104 can be movably connected to the operating table 100 through the L-shaped plate 103, thereby facilitating the cutting of different positions on the expanded polystyrene board on the operating table 100.

[0045] Further as Figure 2 As shown, a PLC controller 801 is fixed on one side of the outer wall of the operating table 100, and the cylinder 203 and the pressure sensor 303 are electrically connected to the PLC controller 801 respectively.

[0046] The PLC controller 801 is configured to receive the pressure value from the pressure sensor 303, thereby facilitating the control of the cylinder 203.

[0047] The distance between the two baffles 800 is the same as the width of the expanded polystyrene board, and the length of the cutting blade 207 is the same as the distance between the two baffles 800.

[0048] In summary: When vertically cutting expanded polystyrene (EPS) boards, the EPS board is first placed on the top surface of the operating table 100. To perform the vertical cutting, the L-shaped plate 103 on one side is pushed, causing the cutting blade 207 to move to the desired cutting position. Then, the PLC controller 801 is activated, starting the cylinder 203. The output end of the cylinder 203 moves, causing the connecting strip 208 to move. The connecting strip 208 then moves the second T-shaped blocks 205 on both sides, which in turn move the cutting blade 207 until it contacts the surface of the EPS board. The output end of the cylinder 203 then continues to move downwards, causing the pressure sensor 303 to move downwards. The pressure sensor 303 then moves the docking post 300 downwards, which in turn moves the cutting blade 207, ultimately causing the cutting blade 207 to make a vertical cut on the EPS board. During the cutting process of the cutting blade 207 on the expanded polystyrene board, the pressure sensor 303 monitors the received pressure value in real time and transmits the signal to the PLC controller 801. The PLC controller 801 compares the received pressure signal with the preset pressure value stored in its internal memory. When the cutting blade 207 has completely cut the expanded polystyrene board, the pressure value monitored by the pressure sensor 303 exceeds the preset pressure value stored in the PLC controller 801. At this time, the PLC controller 801 receives the pressure signal sent by the pressure sensor 303 and compares it with the preset pressure value. If the received pressure is greater than or equal to the preset pressure value, the PLC controller 801 controls the output end of the cylinder 203 to move upward and reset. Then, the L-shaped plate 103 can be pushed so that the cutting blade 207 moves to the next position to be cut. By repeating the above operation, the expanded polystyrene board can be cut at different positions.

[0049] When performing a beveled cut on expanded polystyrene (EPS) board, first, manually pull the rotating ring 601. The movement of the rotating ring 601 drives the gear 400 to move until the gear 400 separates from the rack 403. During this process, the movable disk 502 moves and compresses the spring 501. Then, rotate the rotating ring 601, causing the rotating shaft 200 on that side to rotate. The rotation of the rotating shaft 200 drives the C-shaped frame 201 to rotate. At this time, the cutting blade 207 tilts. While rotating the rotating ring 601, the pointer 701 and the scale 70 can be observed. The pointer 701 is positioned relative to the dial 700 at the corresponding angle. Then, the rotating ring 601 is slowly released, and the spring 501 releases its elastic force to push the movable disk 502. The movable disk 502 pushes the gear 400, so that the gear 400 and the rack 403 are tightly meshed. At this time, the angle of the cutting blade 207 is the angle required for cutting. Then, the polystyrene board can be tilted according to the operation of vertical cutting of polystyrene board. At this time, the polystyrene board can be cut at an angle.

[0050] It can be purchased from the market, and is a mature technology in this field that has been fully disclosed, so it will not be repeated in the specification.
