A table on which a soundproofing plate having one or more hollow portions open on both sides in the front and rear directions is seated;
a strip winding unit disposed in front of the table and wound with a strip provided to penetrate the hollow portion;
A sound-absorbing sheet winding unit disposed at the rear of the table, selectively coupled to an end of the strip, and having a sound-absorbing sheet inserted into the hollow portion wound while moving in conjunction with the strip moving forward by the strip winding unit;
A strip transfer unit disposed between the strip winding unit and the sound insulation plate, and allowing the strip wound around the strip winding unit to pass through the hollow portion and be transferred in the direction of the sound-absorbing sheet winding unit;
a strip winding guide unit disposed between the strip winding unit and the strip transfer unit and guiding the strip wound around the strip winding unit; and
It includes a control unit having an operation lever for controlling the strip winding unit, the strip transfer unit, and the strip winding guide unit,
The strip winding guide unit,
a plurality of pressurizing blocks for pressurizing the strip wound on the first drum of the strip winding unit and seating it in the winding groove of the first drum;
a winding guide drive unit for moving the pressurizing block;
The driving force of the winding guide drive is transmitted to the pressure block, and when the strip is unwound from the first drum, the pressure block is separated from the strip, and when the strip is wound around the first drum, the pressure block is applied to the strip. A soundproofing plate manufacturing device comprising a driving force transmission part that brings the pressurizing block into close contact. According to paragraph 1,
The driving force transmission unit,
A lever member whose one end is coupled to the winding guide drive unit,
a shaft member disposed long in the direction transverse to the strip, coupled to the other end of the lever member and rotating in conjunction with the lever member;
An extension member at one end coupled to the shaft member and extending in the direction of the first drum;
An apparatus for manufacturing a sound insulation plate, comprising a block support member coupled to the other end of the extension member and on a lower surface of which the plurality of pressurizing blocks are coupled. According to paragraph 1,
The strip transfer unit,
a lower roller disposed below the strip,
an upper roller disposed on the upper side of the strip,
a lifting drive unit that narrows or separates the gap between the lower roller and the upper roller with the strip in between;
It includes a roller drive unit that rotates the lower roller or the upper roller,
When the gap between the lower roller and the upper roller is narrowed and the lower roller and the upper roller come into close contact with the strip, the plurality of pressure blocks are spaced apart from the strip,
A sound insulation board manufacturing apparatus, characterized in that when the distance between the lower roller and the upper roller is spaced apart so that the lower roller and the upper roller are spaced apart from the strip, the plurality of pressure blocks are in close contact with the strip. According to paragraph 1,
The control unit,
When the first operation of the operation lever for backward transfer of the strip is performed, a first signal generator that generates a first signal to bring the strip transfer unit into close contact with the strip and simultaneously space the strip winding guide unit away from the strip. and,
A second signal generator that generates a second signal to generate a rotational force of the strip transfer unit and the strip winding unit when the operation lever is operated for rearward transfer of the strip,
A third signal generator that generates a third signal to space the strip transfer unit from the strip and at the same time bring the strip winding guide unit into close contact with the strip during the third operation of the operation lever for forward transfer of the strip. and,
A sound insulation board manufacturing apparatus further comprising a fourth signal generator that generates a fourth signal for generating a rotational force of the strip winding unit when the fourth operation of the operation lever for forward transfer of the strip is performed.
