[0051] Working principle of EPE multi-layer composite extrusion equipment:

[0052] First, according to the number of raw material single layers of the pearl cotton that need to be composited, the required number of layered guide rollers 4 is determined, and according to the stacking order of the raw material single layers of the multi-layer pearl cotton and the corresponding thickness of each layer, the distance between the lowest layered guide roller 4 and the upper surface of the conveyor belt 2 and the distance between two adjacent layered guide rollers 4 are adjusted.

[0053] The motor device is used to drive the threaded rod 5 to rotate, and at the same time, the power-on time of the electromagnetic coil in the electromagnetic group 7 inside the connecting block 41 corresponding to each layered guide roller 4 is controlled. When the electromagnetic coil is in the power-on state, the electromagnetic coil generates a repulsive force on the magnetic block, thereby pushing the threaded ring 6 to engage with the threaded rod 5. The electromagnetic group 7 is used to control the threaded engagement of the threaded ring 6 and the threaded rod 5. When the motor device drives the threaded rod 5 to rotate, the threaded rod 5 engages with the threaded ring 6 to drive the connecting block 41 to move upward or downward, so that the position of the corresponding layered guide roller 4 can be adjusted upward or downward, and then the distance between the lowest layered guide roller 4 and the upper surface of the conveyor belt 2 and the distance between two adjacent layered guide rollers 4 are adapted to the thickness of the corresponding single layer of the raw material of the pearl cotton.

[0054] Then the raw material single layer of the multi-layer pearl cotton passes between the corresponding lowest layered guide roller 4 and the upper surface of the conveyor belt 2 or between two adjacent layered guide rollers 4, and at the same time passes under the pressure roller 81 on one side of the conveyor belt 2, and the cylinder or hydraulic cylinder on the surface of the mounting seat 8 is used to adjust the distance between the pressure roller 81 and the conveyor belt 2, so that the pressure roller 81 contacts the raw material single layer of the uppermost layer of the pearl cotton, and the pressure roller 81 is used to make the raw material single layers of the multi-layer pearl cotton overlap and stick together, and cooperate with the conveyor belt 2 to transport the raw material single layers of the multi-layer pearl cotton.

[0055] When conveying the raw material single layer of the superimposed and bonded multi-layer pearl cotton, first use the upper clamping plate 131 and the lower clamping plate 132 in the clamping plate 13 corresponding to the extrusion platform 9 to clamp the raw material single layer of the multi-layer pearl cotton, and through the sliding of the slide seat 12, the raw material single layer of the multi-layer pearl cotton is clamped to the bottom of the pressing plate 101 until the clamping plate 13 moves to the other side of the extrusion platform 9. At this time, when the pressing plate 101 moves downward to extrude the raw material single layer of the multi-layer pearl cotton, it will not contact the clamping plate 13.

[0056] After the single layer of the raw material of the multi-layer pearl cotton on the surface of the extrusion platform 9 is composite-extruded by the pressing plate 101, the multi-layer pearl cotton that has been composite-extruded is clamped and conveyed by the clamping plate 13 corresponding to the conveyor belt 17, and the pressure roller 81 on the side of the conveyor belt 17 cooperates with the conveyor belt 17 to convey the multi-layer pearl cotton that has been composite-extruded.
