DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a composite nailing device for a fire curtain comprises: a workbench 1, the upper end of which is fixedly connected to a nailing machine 2; a smoothing mechanism 3, which is arranged at the upper end of the workbench 1, and the surface of the smoothing mechanism 3 extends to the inside of the workbench 1; wherein the smoothing mechanism 3 comprises an unfolding component 31 installed at the upper end of the workbench 1, a toggle component 32 is arranged on one side of the unfolding component 31, a straightening component 33 is arranged on the side of the toggle component 32 close to the nailing machine 2, and the straightening component 33 is installed on the surface of the workbench 1;

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the unfolding assembly 31 includes two fixed frames 311 fixedly connected to the upper end of the workbench 1 and a lower frame 314 fixedly connected to the inner wall of the workbench 1, an upper frame 312 is fixedly connected between the two fixed frames 311, a roller 313 is rotatably connected to the inner wall of the upper frame 312, the lower end of the roller 313 extends to the interior of the lower frame 314, both sides of the upper frame 312 are rotatably connected to a rotating shaft 315, one end of the rotating shaft 315 passes through the interior of the upper frame 312 and is fixedly connected to the rotation center of the roller 313, and a rubber belt 316 is fixedly connected to the surface of the rotating shaft 315, and the rubber belt 316 is spiral. The fire curtain is placed on the workbench 1 through the bottom of the fixed frame 311 in turn, and then gradually placed on the workbench 1. At this time, one end of the fire curtain is pulled so that the fire curtain is squeezed in the longitudinal direction under the action of the roller 313, and the squeezed fire curtain is pressed into the lower frame 314. At this time, the fire curtain in the longitudinal direction is positioned by the cooperation of the roller 313 and the lower frame 314, so that the fire curtain is prevented from being offset during the nailing operation.

[0026] At the same time, the roller 313 rotates under the drive of the fireproof curtain. At this time, when the roller 313 rotates, the rotating shafts 315 on both sides are driven to rotate accordingly. The rotation of the rotating shafts 315 drives the rubber belt 316 to rotate synchronously. Since the material of the rubber belt 316 is rubber, and the surface of the rubber belt 316 will contact the fireproof curtain, the fireproof curtain is spread to both sides through the rubber belt 316, thereby avoiding and reducing the stacking and squeezing on both sides.

[0027] like Figure 2 , Figure 4 and Figure 5 The cam 324 is a substantially rectangular shape having a plurality of cams 326 disposed on the top of the cam 326, wherein the cam 326 is provided with a plurality of cams 327 disposed on the top of the cam 326. The cam 324 is a substantially rectangular shape having a plurality of cams 328 disposed on the top of the cam 326. The cam 324 is a substantially rectangular shape having a plurality of cams 329 disposed on the top of the cam 326.

[0028] The straightening assembly 33 includes a mounting frame 331 fixedly connected to one side of the workbench 1, the inner top wall of the mounting frame 331 is hinged with a hinge rod 332, the lower end of the hinge rod 332 is hinged with a straight plate 333, the lower end of the straight plate 333 is provided with a plurality of straight grooves 334, the surface of the hinge rod 332 is fixedly connected with a second spring piece 335, and the second spring piece 335 is fixedly connected to the inner top wall of the mounting frame 331. The second spring piece 335 contacts the hinge rod 332 to drive the straight plate 333 to press on the surface of the fireproof curtain, at which time the straight plate 333 can maintain the straightening effect on the edge of the fireproof curtain, and the straight grooves 334 can assist in keeping the fireproof curtain straight, so that the fireproof curtain can be unfolded and nailed by the nailing machine 2.

[0029] When the utility model is in use, the multi-layer fireproof curtain of the fireproof curtain is passed under the fixed frame 311, and the roller 313 at one end is pulled to press the fireproof curtain into the lower frame 314 to form a position. When the roller 313 rotates, it drives the rotating shafts 315 on both sides to rotate accordingly, so that the rubber belt 316 rotates synchronously, and the fireproof curtain is unfolded to both sides. The first spring piece 325 contacts the pressure plate 323, and the lower end of the pressure plate 323 is close to the surface of the fireproof curtain. The overlapping fireproof curtain is pushed and unfolded by the hard rubber plate 324, and the second spring piece 335 contacts the hinge rod 332 to drive the straight plate 333 to be pressed on the surface of the fireproof curtain. At this time, the straight plate 333 keeps the edge of the fireproof curtain straight and keeps the fireproof curtain straight. When the fireproof curtain is unfolded, it will be nailed by the nail machine 2.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
