By setting the extrusion component 3, specifically through the rebound force of the spring 35, the arc extrusion block 31 and the foam are in closer contact, the foam is rolled up tighter, the gap between the foams is reduced, the foam is not easily scattered, and it will not take up a lot of space. There is no need to manually rewind the scattered foam, thereby improving efficiency.

[0030] A slide rail is fixedly connected to the top of the bottom plate 1, and two movable blocks 13 are slidably connected to the outer surface of the slide rail. The backs of the two movable blocks 13 are fixedly connected to half screws 131, and nuts 132 are threadedly connected to the outer surfaces of the half screws 131.

[0036] A connecting rod 212 is slidably connected to the third inner wall of the sliding groove, and a clamping block 211 is fixedly connected to the front and back sides of the connecting rod 212 . The right output end of the cylinder 21 is fixedly connected to the left side of the clamping block 211 .

[0037] A specific application of this embodiment is:

[0038] When in use, the processed polyurethane foam is transported to the position of the winding drum 122 through the conveying roller 111, and then the foam is wound on the winding drum 122, and the motor 121 is started to drive the winding drum 122 to rotate, and the foam is rolled onto the winding drum 122. During the rolling process, as the foam becomes thicker, the arc extrusion block 31 is squeezed, so that the arc extrusion block 31 slides upward, driving the sliding rod 2 32 and the limiting rod 34 to move upward together, so that the arc extrusion block 31 is close to the sliding plate 33, and then the spring 35 is squeezed. The resilience of the spring 35 makes the arc extrusion block 31 and the foam contact more closely, and the gear 32 is driven by the starting motor 231. When the wheel 232 rotates, the gear teeth on the surface of the threaded ring 234 mesh with the gear 232, so when the gear 232 rotates, the threaded ring 234 is driven to rotate. When the threaded ring 234 rotates, the threaded rod 233 moves upward, thereby driving the sliding plate 33 to move upward together, so that the sliding plate 33 is away from the arc-shaped extrusion block 31. After the foam is rolled up and gradually becomes thicker, the threaded rod 233 also drives the sliding plate 33 to rise synchronously. After the foam is further thickened during the rolling process, the arc-shaped extrusion block 31 will be closer to the sliding plate 33, thereby squeezing the spring 35 tighter. The sliding plate 33 is driven to rise synchronously by the threaded rod 233 without increasing the rebound force, thereby reducing the squeezing of the spring 35. In this way, the foam can be squeezed by the resilience of the spring 35, and the arc-shaped squeezing block 31 will not be too tightly contacted with the foam due to excessive resilience, which may break the foam, and the spring 35 will not be fatigued and damaged due to excessive squeezing of the spring 35, so the service life will not be reduced. When the foam is rolled up, the foam is cut and then packaged, and the arc-shaped squeezing block 31 is pushed to move upward, driving the sliding rod 32 to move together until the sliding rod 32 rises to its place, and the cylinder 21 is started to push the clamping block 211 to approach the sliding rod 32. Since the side of the clamping block 211 away from the cylinder 21 is an arc-shaped setting, the clamping block 211 can be clamped into the groove of the sliding rod 32, The sliding rod 232 is fixed to prevent the arc-shaped extrusion block 31 from falling, and then the nut 132 is rotated counterclockwise to separate the half screw 131, so that the two movable blocks 13 can move, and then the two movable blocks 13 are moved away from the winding drum 122, so that the rolled foam can be removed from the winding drum 122. After removal, the motor 231 is started to drive the threaded ring 234 to rotate so that the threaded rod 233 returns to its position and drives the sliding plate 33 to return to its position, and at the same time, the cylinder 21 is retracted to separate the block 211 from the groove of the sliding rod 232, so that the arc-shaped extrusion block 31 falls, and then the two movable blocks 13 are moved close to the winding drum 122, and after contact, the nut 132 is rotated clockwise to fix the movable blocks 13.
