It can be understood that the sheet processing system 700 produces the cross-linked polyolefin foam through the foaming furnace 500 to produce the sheet 600, the sheet 600 exits from the discharge port 510 of the foaming furnace 500, and blows air to the sheet 600 through the air nozzle assembly 42 of the cooling structure 4 of the sheet unfolding apparatus 100 to cool the sheet 600, so as to adsorb the edge of the sheet 600 through the suction cups 331 of the adsorption structure 3, and then drives the adsorption structure 3 to move along the mounting seat 1 through the driving assembly 2 to drive the sheet 600 to unfold. The sheet material spreading apparatus 100 of the present invention replaces the nip roller, thereby achieving suction and continuous spreading of the sheet material 600 without contacting the entire surface of the sheet material 600.

In the present embodiment, the sheet spreading device 100 is mounted at the discharge port 510 of the foaming furnace 500 of the sheet processing system 700 through the mount 1. The mounting seat 1 may be integrally formed with the foaming furnace 500, for example, by welding or integrally forming, so as to improve the mounting stability of the sheet spreading device 100. Of course, the mounting base 1 may also be detachably mounted on the foaming furnace 500, for example, by using a snap connection, a plug-in fit, a screw connection, a pin connection, or the like, so as to facilitate the assembly, disassembly, replacement, or maintenance of the sheet material unfolding apparatus 100, and improve the convenience of the sheet material unfolding apparatus 100, which is not limited herein.

It can be understood that the mounting base 1 plays a role in mounting, fixing and supporting the driving assembly 2, the adsorption structure 3 and the cooling structure 4, and the structure of the mounting base 1 may be a mounting plate, a mounting shell, a mounting rack, a bracket or a fixing base, which is not limited herein. The driving assembly 2 is disposed on the mounting seat 1, and is used for driving the adsorption structure 3 to move along the mounting seat 1, so that the suction cup 331 of the adsorption structure 3 drives the sheet 600 to unfold. Optionally, the driving assembly 2 may be a structure in which a driving cylinder and a driving motor are matched with a screw rod, and any structure may be used as long as it can drive the adsorption structure 3 to move along the mounting base 1, which is not limited herein.

In the present embodiment, the suction cup 331 of the suction structure 3 may be a plate-shaped suction cup structure, a suction nozzle structure, or the like, and is not limited as long as the suction of the sheet 600 can be achieved. Cooling structure 4 sets up in adsorption structure 3's sucking disc 331 to when sucking disc 331 adsorbs sheet 600, blow to sheet 600 through air nozzle assembly 42, thereby cool off sheet 600, when so making things convenient for sucking disc 331 to adsorb sheet 600, avoid sucking disc 331 and sheet 600 to take place the adhesion.

The sheet material unfolding device 100 not only can conveniently and quickly realize the unfolding of the sheet material 600, but also can effectively avoid the phenomenon that the sheet material 600 is contacted with the whole sheet material and is adhered. It can be understood that the sheet spreading apparatus 100 spreads the cross-linked polyolefin sheet 600 just after foaming by contacting only the edge of the foam sheet 600, and prevents the conventional nip roll from contacting the foam sheet 600 over a large area and damaging the sheet 600.

Two air nozzles 422 are oppositely and spaced to define sheet path 424 at the spacing, thus facilitating sheet 600 to slide down sheet path 424 after exiting outfeed 510. Pre-cooling is achieved by blowing air first into the sheet 600 entering the sheet passage 424 by the air tube 421, then after the sheet 600 enters the sheet passage 424, blowing air simultaneously into both sides of the sheet 600 by the two air nozzles 422, further cooling the sheet 600, and finally sucking the edge position of the sheet 600 located in the sheet passage 424 by the suction cups 331.
