The vibration reduction sheet 1200 is formed under the vibration reduction module 1100 and secondaryly reduces vibration. Specifically, the vibration reducing sheet 1200 is configured to reduce vibration, and includes a sheet member 1210, a transmission member 1220, and a dispersion member 1230.

The sheet member 1210 is formed of a ductile material to disperse vibration due to an upper impact. The sheet member 1210 may be formed of a high-density material so as to have ductility and elasticity so as not to be damaged or deformed by an impact generated from the top. Since the sheet member 1210 is formed of a high-density material, it is possible to minimize the deformation of the state of the sheet member 1210 due to an impact acting on the top of the sheet member 1210. The sheet member 1210 may be formed of at least one material of ductile polyethylene (PE), foamed vinyl acetate (EVA), and foamed polystyrene (EPS) that absorbs shock or vibration caused by the operation of components.

The transmission member 1220 is formed at equal intervals in the lower portion of the sheet portion, and transmits the impact applied to the sheet member 1210 by cohesion to the lower portion. The transmission member 1220 includes a semicircular guide module 1211, a guide module 1211 and a guide module 1211, which guides the vibration acting as the sheet member 1210 to be concentrated to the floor or structure where the vinyl molding apparatus 10 is located. A low-density absorption module 1212 is provided that is softer than the guide module 1211 in order to absorb the vibration generated from the vinyl molding device 10 by being formed at a location where the vinyl molding device 10 is located or the structure is in contact with it. do. The transmission member 1220 may be coupled to the lower portion of the sheet member 1210. The transmission member 1220 may be formed in a semi-circular shape of a hemisphere, and may be provided between the main body 600 and the sheet member 1210 to form a height of the space. The transmission member 1220 is in contact with at least one area of the floor or structure where the vinyl molding device 10 is located, and the vibrations caused by the impact acting on the upper portion of the sheet member 1210 are aggregated to form the floor where the vinyl molding device 10 is located. Can be transferred to the structure. Therefore, the magnitude of the vibration may be determined by the frequency transmitted to the floor or structure on which the vinyl molding apparatus 10 is positioned through the transmission member 1220. As described above, the transmission member 1220 is the guide module 1211 and the absorption module so that the vibration caused by the shock acting as the sheet member 1210 is dispersed and concentrated to the floor or structure where the vinyl molding apparatus 10 is located. (1212) can be provided. The guide module 1211 may be coupled to a lower portion of the seat member 1210 and formed to protrude from the lower portion of the seat member 1210 in a hemispherical shape. In addition, the guide module 1211 may be formed at equal intervals with the dispersion member 1230 so that the vibration transmitted through the sheet member 1210 is guided to the guide module 1211. Since the guide module 1211 is formed in a hemispherical shape, vibration generated when an impact is applied to the top of the sheet member 1210 is dispersed and vibrated when transmitted to the guide module 1211 provided under the sheet member 1210. The vinyl molding apparatus 10 may be guided to be concentrated to the absorption module 1212 in contact with the floor or structure on which it is located. The absorption module 1212 is formed under the guide module 1211, and is formed at a lower density than the guide module 1211 to absorb the vibration to reduce the amount of vibration transmitted to the floor or structure where the vinyl molding device 10 is located. I can make it. In particular, if the guide module 1211 and the absorption module 1212 are formed of a material of the same density, the amount of vibration transmitted through the absorption module 1212 is the same as the amount of vibration transmitted through the guide module 1211. Since the device 10 can be transmitted to the floor or structure where the device 10 is located, the absorption module 1212 may be formed at a low density so that the amount of vibration transmitted by the guide module 1211 can be reduced. In one embodiment, the transmission member 1220 is formed of at least one of polyethylene, foamed vinyl acetate, and foamed polystyrene, which can reduce vibration due to impact so that noise can be generated less like the sheet member 1210. I can.

The dispersion member 1230 is formed at equal intervals between the plurality of transmission members 1220, and is formed in a spiral shape in order to disperse the impact concentrated on the transmission member 1220, and under the buffer module 1231 and the buffer module 1231 It is provided with a contact module 1232 in contact with the body. The dispersing member 1230 may be formed in a space formed between a floor or a structure in which the sheet member 1210 and the vinyl molding apparatus 10 are located by being coupled to a plurality of the lower portions of the sheet member 1210, and a plurality of transmission members ( 1220) can be formed at equal intervals between. The dispersing member 1230 may be formed in a cylinder and may be extended to the lower portion of the sheet member 1210, and a spiral groove is provided in the cylinder to increase the length of the cylinder by an external force such as a spring so that elasticity can be generated. . In this way, the dispersion member 1230 is formed in a spiral shape, and the shock acting as the sheet member 1210 is concentrated to the transmission member 1220 to disperse the amplified frequency of the shock absorbing module 1231 and the shock absorbing module 1231 A contact module 1232 may be provided at the lower part of the panel to contact the floor or structure on which the vinyl molding apparatus 10 is located and provided with a vibration measurement sensor 1300. In addition, the dispersion member 1230 may be formed of at least one of flexible polyethylene, foamed vinyl acetate, and foamed polystyrene, similar to the sheet member 1210 and the delivery member 1220. When an impact occurs on the top of the sheet member 1210 coupled to the top of the dispersion member 1230, the sheet member 1210 may be lowered by a predetermined length by the impact. At this time, since the sheet member 1210 falls downward, the dispersion member 1230 may be coupled to the lower portion of the sheet member 1210 and may be lowered to the same length as the sheet member 1210. When the dispersing member 1230 is lowered to a predetermined length due to an impact, the height of the spirally formed buffer module 1231 is reduced due to elasticity, and when the dispersing member 1230 maintains its original shape again, the dispersed vibration may be extinguished or weakened. . For example, if the dispersion member 1230 does not protrude from the lower portion of the sheet member 1210, vibration caused by the shock generated by the sheet member 1210 is directly transmitted to the transmission member 1220 and passes through the transmission member 1220. It may be transmitted to the floor or structure where the vinyl molding device 10 is located to generate vibration. Therefore, the vibration directly transmitted to the transmission member 1220 by the dispersion member 1230 can be dispersed, and the vibration is removed when the dispersion member 1230 is moved by the buffer module 1231 formed in a spiral shape and the elasticity acts Since it is weakened and can be transmitted to the transmission member 1220, vibration can be reduced.

The vibration measurement sensor 1300 is provided on the lower floor of the vibration reduction sheet 1200 to measure the vibration transmitted from the vibration reduction sheet 1200 and measures the frequency. Specifically, the vibration measurement sensor 1300 is provided in the contact module 1232 to measure the frequency acting on the dispersing member 1230 to generate a measurement value, the sensing unit 1310, for a time when the change of the frequency is within a predetermined range.
