Description

Centreless wrap-up on a kind of wallpaper machine

Technical field

The utility model relates to a kind of printing machinery, more particularly relates to the centreless wrap-up on a kind of wallpaper machine.

Background technology

Along with the progress of science and technology, the variation of people's lives, individual demand can get more and more.Wallpaper is as the also increasing favor that receives broad masses of the ornament materials of a kind of environmental protection, low-carbon (LC).In order to adapt to the needs of modern's home decoration, the rolling length of wallpaper is difficult for long, is generally ten meters of every volumes.At present; Wrap-up on the existing wallpaper machine mainly contains off-line three roller centreless rollings; Or netlist roller or pneumatic vertex of a cone rolling; This wrap-up exists the centreless rolling of problem, especially lines such as speed is slow, efficient is low, the low needs that satisfied not printing industry fast development now of its speed.

Summary of the invention

In order to solve the problems referred to above that exist in the prior art, the utility model provides the centreless wrap-up on the wallpaper machine that a kind of speed is fast, efficient is high.

The utility model is realized through following technical scheme: the centreless wrap-up on a kind of wallpaper machine; Comprise wallboard and be arranged on the cross-section device between two wallboards; Below cross-section device, be provided with two feeding rollers in relative rotation, below feeding roller, be provided with the fixedly crimping roller of two equidirectional rotations, two fixedly are provided with curling piece between the crimping roller; Between two wallboards on the fixing right side of crimping roller, be provided with swing arm; The left end of swing arm is provided with the active volume curved roll of two equidirectional rotations, and the right-hand member of swing arm is connected with the cylinder that the control swing arm is rotated, and the lower dead center place is provided with limited block respectively in the rotation of wallboard top link right-hand member.

The beneficial effect of the centreless wrap-up on the utility model wallpaper machine is:

The crimping roller of this centreless wrap-up is provided with four, and two active volume curved rolls can move up and down, and makes the rolling speed of material film be improved, and simultaneously, the rolling of material film is accomplished with collecting automatically, has improved the efficient of rolling.

Fig. 3 is the structural representation that is in the blowing position after the centreless wrap-up rolling on the utility model wallpaper machine is accomplished.

Among the figure: 1. material film, 2. cylinder, 3. carry-over pinch rolls, 4. the traction pressure roller is 5. gone up rotor, 6. fixing cutter down; 7. feeding roller, 8. fixing crimping roller, the piece that 9. curls, 10. active volume curved roll, 11. receiving hoppers, 12. swing arms; 13. the swing arm rotating shaft, 14. cylinders, 15. upper limit position blocks, 16. lower position blocks, 17. curling chambeies.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the centreless wrap-up on the utility model wallpaper machine is done further to describe:

Fig. 1 is the structural representation of the centreless wrap-up on the utility model wallpaper machine; Among the figure; Carry-over pinch rolls 3 are arranged on the top of this wrap-up; The next door of carry-over pinch rolls 3 is provided with traction pressure roller 4, and traction pressure roller 4 is pressed on the carry-over pinch rolls 3 through the effect of cylinder 2, below carry-over pinch rolls 3, is provided with cross-section device.Below cross-section device, be provided with two feeding rollers 7 in relative rotation; Below feeding roller 7, be provided with the fixedly crimping roller 8 of two equidirectional rotations; Two fixedly are provided with the piece 9 that curls between the crimping roller 8; Between two wallboards on the fixing right side of crimping roller 8, be provided with swing arm 12, the left end of swing arm 12 is provided with the active volume curved roll 10 of two equidirectional rotations, and the right-hand member of swing arm 12 is connected with the cylinder 14 that the control swing arm is rotated; The lower dead center place respectively is provided with upper limit position block 15 and lower position block 16 in the rotation of wallboard top link 12 right-hand members, is provided with receiving hopper 11 on the left side of swing arm 12.

Fig. 2 is the zoomed-in view at A place among Fig. 1, and among the figure, the active volume curved roll 10 in the swing arm forwards top dead center position to, and fixedly crimping roller 8 is common forms a curling chamber 17 for two active volume curved rolls 10 and two.

Fig. 3 is the structural representation that is in the blowing position after the centreless wrap-up rolling on the utility model wallpaper machine is accomplished.Among the figure, the stretching out of cylinder 14 extension bars, swing arm 12 is rotated, and its right-hand member is by upper limit position block 15 restrictions, and the active volume curved roll 10 in the swing arm 12 reaches bottom dead center position.

During work, the contraction of cylinder 14, swing arm 12 is rotated, and its right-hand member is by lower position block 16 restrictions, and the active volume curved roll 10 in the swing arm 12 reaches top dead center position, and at this moment, fixedly crimping roller 8 is common forms a curling chamber 17 for two active volume curved rolls 10 and two.Material film 1 through increasing tension force enters into carry-over pinch rolls 3 through guide roller; Carry-over pinch rolls 3 are by AC servo machinery driving, and it is long to utilize the AC servo encoder to calculate material through PLC, guarantee to expect long meeting the requirements; Traction pressure roller 4 is pressed through cylinder 2 clutches, guarantees the speed of traction material film 1.Down to cross-section device, mainly be made up of last rotor 5 and fixing cutter 6 down by cross-section device after the traction of carry-over pinch rolls 3 for material film 1, and after metering length reached, material film 1 was cut off in last rotor 5 rotations.Material film 1 gets into fixedly crimping roller 8 through feeding roller 7; Run into the active volume curved roll 10 that clockwise rotates again downwards; Material film 1 along with two active volume curved rolls 10 and two fixedly crimping roller 8 clockwise rotate rolling counterclockwise in curling chamber 17, under the effect of the piece 9 that curls, material film 1 formation web-like; Reach the length of setting, accomplish the centreless rolling.Subsequently, the extension bar of cylinder 14 stretches out, and swing arm 12 rotates counterclockwise, and its right-hand member is by upper limit position block 15 restrictions, and the active volume curved roll 10 in the swing arm 12 reaches bottom dead center position, and the material scroll of spooling is in receiving hopper 11.

This centreless wrap-up makes the rolling speed of material film be improved, and simultaneously, the rolling of material film is accomplished with collecting automatically, has improved the efficient of rolling.
