Abstract: The disclosure belongs to the technical field of soundproof flooring, and discloses a floor mat and a floor. The floor mat includes a floor mat body made of foamed material. At least one surface of the floor mat body is provided with a number of soundproof units with the same area. Each of the soundproof unit has at least one soundproof structure. At least one of the numbers, shapes and distribution positions of the soundproof structures are different. The floor mat of the present disclosure can play a sound absorption effect; at the same time, a plurality of chaotic sounds are dispersed and mutually offset, which effectively isolates most of the sounds and has a good soundproof effect.

Abstract: The present invention relates to a spreading device for a foaming furnace, including a first spreading component and a second spreading component symmetrically mounted on two sides in a hearth of a foaming furnace. Both the first spreading component and the second spreading component are provided with a spreading roll group composed of at least two spreading rolls, and a driving device for driving the spreading roll group. The spreading device further includes a fixing frame, the fixing frame including a first mounting seat and a second mounting seat. The spreading roll includes a first mounting portion and a second mounting portion. The first mounting portion is rotationally connected to the first mounting seat, and the second mounting portion is rotationally connected to the second mounting seat. The spreading device of the present invention has good stability during work, and significantly improves an unfolding effect.
