Description

The drag hook device of the dynamo-electric heated filament of plastic bag sealing

The utility model relates to the heating wire drag hook device of plastic bag sealing machine, is used for tractive, fixing heating wire.

The drag hook device of the dynamo-electric heated filament of existing plastic bag sealing is such: with the elastic sheet metal o ing like English alphabet V, right and left shoulders broad but, be the V shape, one shoulder is fixed on the board, another shoulder is with the annulus phase hook of end element conneccting, two drag hook devices are close to heating wire on the insulating barrier, and insulating barrier is close to down on the aluminum strip.Its weak point is: pulling force shakiness, the elasticity of drag hook sheetmetal are tired easily, cause the stretching elasticity to be difficult to control, and heating wire comes off easily.

The purpose of this utility model is to avoid above-mentioned weak point and provides that durable, pulling force is stable, the drag hook device of the dynamo-electric heated filament of the plastic bag sealing of heating wire difficult drop-off.The purpose of this utility model can reach by following technical solution:

The utility model is made up of drag hook seat, stage clip, compression spring axis, the drag hook seat partly is made up of fixed part component and drag hook, respectively there is relative aperture the both sides, one end of fixed part, also respectively there is relative aperture the both sides, one end of drag hook part, there is gib head its other end, compression spring axis runs through stage clip, and the both sides aperture snare compression spring axis of fixed part, drag hook part is also fastening and obtain connecting.

The utility model advantage: durable, pulling force is stablized, the heating wire difficult drop-off.

Below in conjunction with accompanying drawing the utility model is described in detail

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model device scheme drawings when using on the plastic bag sealing machine

As Fig. 1, shown in 2, the utility model is by drag hook seat, stage clip 4, take spring axle 6 by force and form, the drag hook seat is made up of fixed part 15 and drag hook part 14, and respectively there is relative aperture 5 both sides, an end of fixed part 15, also respectively there is relative aperture 5 both sides, one end of drag hook part, there is gib head 2 its other end, and compression spring axis 6 runs through stage clip 4, and the both sides aperture of fixed part 15, drag hook part 14 5 snare compression spring axis 6 are also fastening and obtain connecting.Fixed part 15 is that some angles have been rolled up on sheetmetal both sides 7, be generally 90 °, the groove that forms, respectively there is relative aperture 5 both sides, groove one end, and bottom land has fixed orifice 1, and drag hook part 14 is that some angles have been rolled up on sheetmetal both sides 3, be generally 90 °, the groove that forms, also, respectively there is aperture 5 both sides, groove one end, and there is gib head 2 end at the bottom of the groove.Fastening means can riveting mode, also available screw is fastening, the drag hook device connects with power supply.When the utility model uses, with the fixed orifice 1 of screw 12 by drag hook seat fixed part 15 the drag hook seat because of fixing on the machine bench 13, the roundlet annular distance rank clasp head 2 of joint 9 ends of heating wire 10, fix a drag hook device equally at the opposite side of machine bench 13, heating wire 10 is close on the following aluminum strip 11, but an insulating barrier 16 is arranged between heating wire 10 and the following aluminum strip 11, following aluminum strip is actually 90 ° arch shape thing, be prior art, the 8th, the screw of connection power supply.

Claims (2)

1, the drag hook loading amount of the dynamo-electric heated filament of plastic bag sealing, it is characterized in that: form by drag hook seat, stage clip (4), compression spring axis (6), the drag hook seat is made up of fixed part (15) and drag hook part (14), respectively there is relative aperture (5) both sides, one end of fixed part (15), also respectively there is relative aperture (5) both sides, one end of drag hook part (14), there is gib head (2) its other end, compression spring axis (6) runs through stage clip (4), and both sides aperture (5) the snare compression spring axis (6) of fixed part (15), drag hook part (14) is also fastening and obtain connecting.

2, ask 1 described drag hook device by right, it is characterized in that: said fixed part (15) is that sheetmetal both sides (7) have been rolled up some angles, be generally 90 °, the groove that forms, respectively there is relative aperture (5) both sides, groove one end, bottom land has fixed orifice (1), drag hook part (14) is that sheetmetal both sides (3) have been rolled up some angles, is generally 90 °, the groove that forms, also respectively there is aperture (5) both sides, groove one end, and there is gib head (2) end at the bottom of the groove.
