[0028] Embodiment Two:

[0029] Please refer to Figures 1 to 6 , for a modular magnetic adsorption type cloth pressing and guiding roller of the present invention, compared with Embodiment One, this embodiment further includes: The connection assembly 5 includes a clamping plate 51 fixedly installed on the side of the roller body 31; a microporous plate 52 is fixedly installed through bolts at the central through hole of the clamping plate 51; a conductive member 53 is fixedly installed through bolts at the through hole inside the microporous plate 52; a telescopic tube 54 with a protection function is fixedly installed by adhesion on the outer ring of the side of the clamping plate 51, a through hole is opened at the top of the telescopic tube 54, and the through hole is connected to an external air pipe through a connecting pipe; the clamping plate 51 is fixedly installed on the left and right sides of the second propulsion sleeve 55; a torsion spring 56 with a reset function is fixedly welded to the rear end of the second propulsion sleeve 55, and the torsion spring 56 is fixedly arranged on the front and rear sides of the reel 57.

[0030] Both the quick power connection assembly 33 and the conductive member 53 are composed of an insulating plate, a power connection piece arranged on the insulating plate, and a cable.

[0031] Both the first propulsion sleeve 353 and the second propulsion sleeve 55 are composed of an insulating outer cylinder, coils arranged on the inner wall of the insulating outer cylinder, and a columnar coil block slidably arranged inside the insulating outer cylinder.

[0032] The joint surface of the pallet 51 and the roller body 31 is provided with a self-aligning conical boss, and the surface of the microporous plate 52 is provided with an annular groove concentric with the conductive member 53, and a magnetic sealing ring is embedded in the groove; the telescopic tube 54 adopts a multi-layer corrugated metal tube structure, and an insulating shielding layer 541 is laid on its inner wall.

[0033] Based on the above, the working principle of a modular magnetic adsorption pressing cloth guide roller of a cloth laying machine is as follows: When using this device, first place this device in the working area, and then connect the device to an external power supply to provide the power required for the operation of this device; during the multi-section installation process of the modular roller 3, the pallet 51 on the side of the roller body 31 is physically docked with the corresponding structure of the adjacent roller, and the self-aligning conical boss is embedded in the annular groove of the adjacent module. The magnetic sealing ring is used to enhance the sealing and adsorption force of the joint surface. The conductive member 53 provided at the center of the pallet 51 is automatically aligned and conducted with the quick power connection assembly 33 to achieve the transmission of power and signals between modules; At the same time, the telescopic tube 54 on the outer ring of the pallet 51 expands and contracts under the electromagnetic drive of the second propulsion sleeve 55. Here, the coil inside the second propulsion sleeve 55 is energized to push the columnar coil block inside it to slide outwards. The rod body on the side of the second propulsion sleeve 55 drives the adjacent two pallets 51 to adjust the distance to ensure the tightness of the axial connection of the roller; the single-body controller 325 in the quick power connection assembly 33 and the magnetic conduction assembly 324 energizes the electric control switch 324 and the electromagnet 323 to form a closed-loop feedback system to adjust the energization intensity of the electromagnet 323 in real time to adjust its magnetic adsorption intensity. Here, the electromagnet 323 and the wire mesh 36 outside the roller body 31 are affected by the magnetic field factor of the electromagnet 323 to realize the applicable magnetic levitation phenomenon; Then, the metal wire assembly 35 in the guide roller body 31 is linked with the first propulsion sleeve 353 through the magnetic isolation rod 354. Here, the first propulsion sleeve 353 has the same internal structure as the second propulsion sleeve 55. The first propulsion sleeve 353 pushes the bottom plate 355 to slide inside the limiting cylinder 351, and under the reset action of the reset spring 352, the bottom plate 355 can pull the metal wire 356 to reset after the first propulsion sleeve 353 is powered off. At the same time, the reset action of the limiting spring 357 can also enable the metal wire 356 to dynamically compensate for the connection tension when it extends out of the limiting cylinder 351, so that the metal wire 356 forms a semicircular structure on the outside of the guide roller body 31. By setting two groups of metal wires 356, a complete circle can be formed on the outside of the guide roller body 31. During the cloth pressing and guiding process, the metal wires 356 can be used to contact the cloth to reduce friction. At the same time, zero-contact and zero-friction transmission can be achieved under the rotation of the metal wires 356 and the guide roller body 31. Under the gas diversion effect of the top connecting tube of the telescopic tube 54, the air flow is discharged from the inside of the guide roller body 31 through the conical air holes 37. When the gas flows through the electromagnet 323, it can take away heat and blow it out on the surface of the guide roller body 31 to form a small-scale air pressure environment. Through the dual coordination of magnetic field regulation and gas flow, a certain degree of contactless transmission can be achieved.

[0034] The present invention provides a modular magnetic cloth pressing guide roller for a spreading machine through improvement. Through the physical docking of the conical boss on the side of the guide roller body 31 and the annular groove and the magnetic sealing ring adsorption design, it can quickly be positioned and connected with the connecting component 5, and the electromagnetic drive mechanism of the connecting component 5 can dynamically adjust the distance between the telescopic tube 54 and the guide roller body 31 to ensure the tightness of the axial connection; the magnetic suspension system controlled by the closed-loop feedback of the electromagnet 323 and the rotation of the guide roller body 31 are combined, and the magnetic field strength is adjusted in real time and the airflow diversion and heat dissipation design are integrated to achieve contactless and zero-friction transmission of the cloth, and a full-circular low-friction contact interface is dynamically formed with the help of the adaptive tension compensation structure of the metal wire assembly; the synergistic effect realizes a modular guide roller structure with high reliability and dynamic adaptive capability.
