[0002] Paper, also known as kraft paper, is usually yellow-brown in color and has high tear resistance and dynamic strength. It is generally used to carry the foaming mixture at the bottom of the continuous foaming production line. In the continuous foaming production line of polyurethane soft foam, since the initial state of the foaming material is a fluid mixture, as the foaming reaction proceeds, the foaming mixture undergoes chemical reactions and gradually forms a foamed product with very uniform pores. There are two types of polyurethane foam plastics. The soft open-cell type is similar to sponge and is widely used in various seats, sofa cushions, and sound-absorbing filter materials; the hard closed-cell type is used for heat preservation, insulation, shock absorption, and floating.

[0028] The above-mentioned mounting plate 5 has symmetrically protruding limit blocks on both sides, and the fixing plate 7 has symmetrically opened limit grooves on the inner side. The limit grooves and the limit blocks cooperate with each other to slide. The cooperation between the limit blocks and the limit grooves can ensure that the mounting plate 5 can slide up and down stably.

[0029] like Figure 1 and Figure 4 As shown, a slideway 71 is vertically provided on the outer side edge of the fixed plate 7, and an arc-shaped guide plate 6 is slidably provided in the slideway 71.
