Description

The paper machine is moved back in High-Speed Automatic splicing

Technical field

The utility model relates to paper making equipment, moves back the paper machine in particular for the splicing of coating process.

Background technology

Current, the paper machine is moved back in the revolution shaft type splicing that use in the coating process outside machine in domestic paper mill, and a part will be by manual splicing, be after old paper roll has been put, by manually drawing new paper roll and its paper being pasted on the paper tail of old paper roll, to continue to move back paper, inefficiency.Another part is to move back on the paper machine basis in the splicing of manually splicing, be provided with by the swing arm pressing roll mechanism of switch control by the colour code induction, can realize artificial auxiliary semi-automatic paper receiving---when old paper roll is about to put, by manually pressing switch, the swing arm pressing roll mechanism is interrupted old paper roll and its paper tail is crimped on the new paper roll that posts viscose glue in advance.

No matter be that the paper machine is moved back in splicing manual splicing or semi-automatic paper receiving, its structure is all fairly simple, rigidity and intensity a little less than, can only carry small size wide paper roll, and can not high-speed cruising, the speed of a motor vehicle is general≤300m/min, fabric width≤1760mm, and fabric width is non-adjustable, can't adapt to the production needs of the high speed of a motor vehicle and big fabric width, seriously restricts the lifting of production output and scale.In addition, be used for the pivoted arm pressing roll mechanism of semi-automatic paper receiving, mechanism is simple, action is rough, and is bigger to workman's skilled operation dependence when manually auxiliary, makes the success ratio of splicing not high, broken, shut down often, the time is long, causes productive costs higher.

Summary of the invention

The purpose of this utility model is the paper machine to be moved back in existing splicing improve, and provides a kind of High-Speed Automatic splicing to move back the paper machine, makes it to become to carry out the equipment that big fabric width paper roll is produced under the high speed of a motor vehicle, and realize automatic splicing change of lap under the high speed of a motor vehicle.In addition, to realize that also the clamping fabric width of paper roll is adjustable arbitrarily in 2200～2800mm scope.

Above-mentioned purpose can realize by such technical scheme: the paper machine is moved back in the High-Speed Automatic splicing that is provided, have by the axis of revolution that is connected in worm gearing, connect firmly the guide rolls support support body on axis of revolution and be loaded on the station turret mount that a pair of revoliving arm constituted of axis of revolution with the guide rolls support support body 90 ° of orientation that are separated by, the two ends of described revoliving arm are equipped with and are moved back the paper bobbin clamping device, wherein two on the single-revolution arm moves back the paper bobbin clamping device, respectively by coupling mechanism with move back the paper driver train and link, it is characterized in that, has the rotary disk that connects firmly on axis of revolution, rotary disk has bracket, will move back the paper driver train and move back coupling mechanism that the paper bobbin clamping mechanism links and pass rotary disk and be supported by it; Side at described station turret mount, be provided with the automatic splicer structure, this mechanism has dancing roll, air roll and disconnected paper cutter, three's two ends are associated with the swing arm by air cylinder driven, dancing roll centering is connected in the root of described swing arm, and air roll and disconnected paper cutter respectively are connected in the top of described swing arm by a cover lever hinged-support and the cylinder that links thereof; On the described guide rolls support support body, the screw mandrel of one band driving interface is housed, positive and negative silk travelling nut is housed on the screw mandrel, described a pair of revoliving arm is connected in axis of revolution with feather key, revoliving arm and positive and negative silk travelling nut fuse one by one, are contained in to move back the paper bobbin clamping device and move back between the paper driver train and install moving sets on the coupling mechanism.

The beneficial effect that the utility model is compared with prior art presented is:

1, by the rotary disk with bracket is set on axis of revolution, make axis of revolution a firm strong support arranged at power end, and will move back the paper driver train and move back the coupling mechanism that the paper bobbin clamping device links and dynamically supported by rotary disk down, the bulk strength and the rigidity that make splicing move back the paper machine like this are able to remarkable enhancing, improved the motion rigidity of complete machine greatly, stable during load running, reliable, thereby can under high speed, move, maximum speed reaches 600m/min, before improving, double, provide condition for improving output; The raising of complete machine intensity and rigidity also makes the fabric width of producing paper roll be increased, and can reach 2800mm, makes that yield of unit time greatly improves under the identical speed of a motor vehicle, thereby the bottleneck of restriction production output and scale is broken.

2, be provided with the automatic splicer structure that three-stage cylinder drives, can be by means of computer controlled, realization large, medium and small action from coarse to fine distributes, make mechanism's splicing flexible movements and precisely, thereby under high speed, realize flying automatically to connect, greatly improved production efficiency, realized rational coupling with high speed of a motor vehicle paper roll operation.

3, by screw pair being set and revoliving arm and axis of revolution being taked to be slidingly connected, make every pair of distance of moving back between the paper bobbin clamping device can realize increase and decrease, thereby the clamping fabric width can be regulated in 2200～2800mm scope arbitrarily, satisfy the production of multiple fabric width kind paper, make the production alerting ability of equipment strong, wide adaptability.
