Description

Filling machine packaging bag servo-actuated closing device

Technical field

The present invention relates to the packaging bag enclosing device on the bottle placer, the packaging bag enclosing device on specifically a kind of moulding bag filling machine.

Background technology

At present, one type of moulding bag filling machine on the market basically all adopts the mode with round turntable multistation rotation can, packing, and the infrastructure mode of this mode is; On the edge of round turntable, be evenly equipped with some holding devices; The corresponding supporting closing device that has on each holding device is provided with in the round turntable outside and send bag mechanism, on each holding device, send bag through sending bag mechanism; After packaging bag can completion in the holding device clamping, seal by closing device.Sealing of existing moulding bag filling machine is after can is accomplished; Dial rotation is sealed by closing device during to next station again; The structures shape of its closing device its rotating disk adopts is the step wise rotating manner; So as to suspend at rotating disk, closing device is accomplished and is sealed, when packaging bag freely falls, again by sending bag mechanism to supply bag to holding device, but the rotating disk of stepping constantly starting-stopping-having consumed a large amount of effective time in the process that starts; The work efficiency of equipment is lower, and the power consumption of the frequent starting of rotating disk, arrestment is also bigger.

Summary of the invention

The object of the present invention is to provide a kind of filling machine packaging bag servo-actuated closing device, this device can realize that clamp assemblies cooperates with closing component accurately in the running continuously at rotating disk, accomplishes sealing packaging bag.

For realizing above-mentioned purpose, the present invention adopts following scheme: filling machine packaging bag servo-actuated closing device, and it has a rotating disk and some clamp assemblies; Clamp assemblies is uniformly distributed with on the edge of rotating disk, is provided with a track in the rotating disk outside, and the cliding seat with its bearing fit is housed on the track; Be provided with the cooresponding closing component of clamp assemblies on some and the rotating disk on the cliding seat, closing component includes cylinder and end socket, and end socket connects with the front end of cylinder piston rod; Cliding seat is provided with positioning component, and positioning component includes a cylinder and a pusher dog, and cylinder is fixed on the cliding seat; Pusher dog is hinged on the cliding seat and is hinged with the front end of cylinder piston rod; Have the block piece that cooperates with pusher dog on the rotating disk, be fixed with on the track one with the cliding seat front end near near switch, track and cliding seat between be connected with spring.

Visible by such scheme, rotating disk is in rotation, and the packaging bag can on one group of clamp assemblies is accomplished; And when this group clamp assemblies goes to the residing side of track, the pusher dog of positioning component is stretched out, the block piece that rotating disk is provided with in rotation then can with pusher dog against; Through pusher dog and block piece against, can make that each closing component on the cliding seat is aimed at each clamp assemblies of this group on the rotating disk one by one, at this moment; Block piece can promote pusher dog and slide in orbit together with cliding seat, cliding seat with leave certain distance near switch after, can send signal near switch; The cylinder promotion end socket of each closing component is stretched out, through the end socket of each closing component and cooperating one by one of each clamp assemblies, can be in the motion of rotating disk; With the packaging bag enclosing on this group clamp assemblies, after sealing completion, make the end socket withdrawal of pusher dog and each closing component of positioning component; Under the effect of spring, cliding seat meeting reposition, and then the good packaging bag of can on next group clamp assemblies is sealed; Constantly move in circles according to this, can be implemented in the continuous running of rotating disk, the packaging bag enclosing after constantly can being accomplished.

Rational in infrastructure, the dependable performance of the present invention; Each closing component on the cliding seat can be accomplished sealing packaging bag in following the process of dial rotation; Avoided this working process of rotating disk frequent starting-stop-starting; Guarantee the at the uniform velocity running of rotating disk ability all-the-time stable, thereby improved efficiency of equipment greatly; And in sealing journey, each closing component on the cliding seat cooperates accurately with the clamp assemblies of rotating disk, and the sealing effect of packaging bag is good.
