It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Herein, the rear means the front and rear directions in the direction in which the EPS sheet moves, i.e., the direction of the straight arrow in fig. 4.

Referring to fig. 1-4, the blowing mechanism of the EPS sheet production system provided by the present invention includes a frame 1 disposed at the downstream of a forming mold 90 of the EPS sheet production system, a blower 2 and an electric cabinet 3 disposed on the frame, a cylindrical guide cylinder 4 fixed at the top of the electric cabinet, and a cutter 5 disposed at the rear side of the guide cylinder; the front end of the guide cylinder is right opposite to the outlet of the forming die 90, and the guide cylinder is provided with an air inlet pipe 4.1 which penetrates through the front end and the rear end and a plurality of air return holes 4.2 which are communicated with the front end and the rear end; the blower is connected with the rear end of the air inlet pipe 4.1 through a gas transmission pipe 2.1; the cutter is used for cutting the cylindrical EPS sheet 91 from the lower side; the blower is electrically connected with the electric cabinet, and the electric cabinet controls the blower to work.

Referring to fig. 4, the working principle is as follows: after foaming, the PS material is ejected from the forming die 90 in a cone shape, the air is blown from back to front in the air inlet pipe (in the direction of the curved arrow in the figure), the ejected EPS material is blown to expand, the air flow flows out from the air return hole after hitting the EPS material, and then the expanded EPS material moves backward along the circumferential surface of the guide cylinder under the traction of the winding machine of the EPS sheet production system, so as to form a cylindrical sheet, and when the cylindrical sheet moves to the cutter position, the cylindrical sheet is cut by the cutter from the lower side to become a flattened sheet (the sheet is flattened by the winding machine of the EPS sheet production system). Therefore, the air blowing mechanism can make the EPS materials sprayed out of the forming die into sheets.
