[0021] Further, such as Figure 5 As shown, a leakage hole is opened on the outer wall of the support plate 5 corresponding to the air outlet box 303 to facilitate the falling of the cut foam.

[0022] In this embodiment, the cutting method for foam production comprises the following steps: Step 1: Place the foam roll 1 on the support frame 2, and pass through the pressure roller 6 and the conveying roller 205 in sequence. The dust suction pipe 9 is connected to the vacuum cleaner, and the air intake pipe 301 is connected to the air pump. After the external power supply is connected, the double-axis motor 101 is controlled to rotate through the control panel 3. The double-axis motor 101 drives the first round rod 102 to rotate, and the first round rod 102 drives the cam 108 to rotate. The cam 108 squeezes the fixed frame 107. The movement trajectory of the fixed frame 107 is the first time: horizontally moving toward the side of the conveying roller 205, the second time: vertically moving downward, the third time: horizontally moving away from the conveying roller 205, the fourth time: vertically moving upward, and so on; Step 2: When the fixed frame 107 moves horizontally toward the conveying roller 205, the fixed frame 107 drives the second support rod 106 to slide in the first slide groove 104, and at the same time, the fixed frame 107 squeezes the first rack 201, and the first rack 201 squeezes the first spring 202 and drives the one-way gear 204 to rotate, and the one-way gear 204 drives the conveying roller 205 to rotate, and the conveying roller 205 drives the foam roll 1 to move a certain distance, thereby completing the unwinding of the foam roll 1; Step 3: After the conveying roller 205 conveys the foam roll 1 for a certain distance, the fixed frame 107 moves vertically downward, and the fixed frame 107 drives the second support rod 106 and the third support rod 109 to descend. The second support rod 106 drives the first support rod 105 to descend through the limit block 103. The first support rod 105 drives the first slide bar 7, the second slide bar 10 and the third slide bar 302 to descend. The first slide bar 7 drives the vibrating knife 8 to descend to cut the foam roll 1. At the same time, the second slide bar 10 drives the collecting box 11 to abut against the foam roll 1 on the support plate 5 to fix the foam roll 1 to prevent it from moving. At the same time, the vacuum cleaner works, and the cut debris is collected through the vacuum pipe 9. Step 4: When the third support rod 109 descends, it will enter the second slide groove 307 on the fourth slide bar 308, and then the fixed frame 107 will move horizontally away from the conveying roller 205. The third support rod 109 drives the fourth slide bar 308 to move, squeezing the second spring 309 while driving the second rack 305 to move. The second rack 305 drives the gear 304 to rotate, and the gear 304 drives the incomplete gear 315 to rotate. At this time, the toothed parts of the incomplete gear 315 are respectively meshed with the third rack 313 and the fourth rack 314, and the fourth rack 314 will stretch the third spring 312, the third rack 313 will squeeze the third spring 312, and when the toothless part of the incomplete gear 315 is respectively engaged with the third rack 313 and the fourth rack 314, the third spring 312 located below the third rack 313 pops out, and the third rack 313 knocks on one side of the foam roll 1, and the fourth rack 314 does not knock. At the same time, the external air pump inflates the air inlet pipe 301 to allow the gas to enter the air outlet box 303. As the gas pressure inside the air outlet box 303 increases and the third rack 313 knocks, the cut finished product can be quickly dropped off to complete the separation; When the fixed frame 107 moves horizontally away from the conveying roller 205, the fixed frame 107 no longer presses the first rack 201, and the first spring 202 stretches to drive the first rack 201 to move. Since the one-way gear 204 does not work at this time, the foam roll 1 will not be conveyed; When the fixing frame 107 moves vertically upward, the fixing frame 107 drives the third support rod 109 to rise and disengage from the second sliding groove 307. At this time, the second spring 309 stretches and pushes the fourth sliding rod 308 to move. The fourth sliding rod 308 drives the second rack 305 to move. The second rack 305 drives the gear 304 to rotate in the opposite direction. The gear 304 drives the incomplete gear 315 to rotate in the opposite direction. At this time, the toothed part of the incomplete gear 315 is respectively engaged with the third rack 313 and the fourth rack 314, the third rack 313 stretches the third spring 312, and the fourth rack 314 compresses the third spring 312. When the toothless part of the incomplete gear 315 is respectively engaged with the third rack 313 and the fourth rack 314, the third spring 312 located under the fourth rack 314 pops out, and the fourth rack 314 knocks on the other side of the foam roll 1 to prevent adhesion and incomplete separation. When the fixed frame 107 moves vertically upward, the first support rod 105 is driven upward by the second support rod 106 and the limit block 103, and the first support rod 105 drives the first slide bar 7, the second slide bar 10 and the third slide bar 302 to move upward. At this time, the vibrating knife 8, the collecting box 11 and the air outlet box 303 are away from the foam roll 1. When the cam 108 rotates again, the fixed frame 107 moves horizontally to the side of the conveying roller 205 again, and so on, the foam cutting production can be completed.
