Abstract
The utility model discloses a vacuum drum axle for a paper roll, establish at the epaxial bar vacuum adsorption pond of axle body on the surface, establish at this internal real empty room of axle, with the aperture of real empty room and vacuum adsorption pond intercommunication including the axle body, along the axial. The utility model discloses a strip vacuum adsorption pond holds paper edge and plays a roll, and adsorption area is big, and suction is full-purpose at the edge of paper, makes the difficult bounce-back of paper break away from. The vacuum adsorption pond is bar-shaped structure, under the condition that does not influence vacuum adsorption effect, can adopt narrower opening, and the paper can not be inhaled the reentrant, has solved the problem of paper-back pipe difficulty. Because each strip-shaped vacuum adsorption tank is communicated with the main vacuum chamber only through one small hole, when broken paper or paper shift deviation occurs in the area, the vacuum suction force is not greatly reduced, and a normal paper winding cylinder can be ensured.
Description
Technical Field
The utility model belongs to fireworks machinery, concretely relates to vacuum drum axle for a paper roll.
Background
The existing fireworks winding machine generally adopts a vacuum winding shaft to wind a paper tube. The edge of paper head is sucked through a row of alternate small holes processed on the shaft by the vacuum drum shaft, and the problem that the rolled paper drum cannot be withdrawn due to the fact that the suction force is insufficient in the hole hour and the large paper in the hole is deformed and recessed frequently occurs in the paper drum rolling process. In addition, when the paper is slightly damaged, the air entering the two holes quickly loses vacuum, and the paper cannot continuously and normally work.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the problem that prior art exists, provide a vacuum drum axle that is used for a paper roll that job stabilization, product quality are good.
Realize the utility model discloses the technical scheme that the purpose was adopted as follows:
the utility model provides a vacuum reel axle for a paper roll, establish at the epaxial bar vacuum adsorption pond of axle body on the surface, establish at this internal real empty room of axle, with the aperture of real empty room and vacuum adsorption pond intercommunication including the axle body, along the axial.
The strip-shaped vacuum adsorption tanks are distributed along the axial direction.
One end of the shaft body is provided with an air passage communicated with the vacuum chamber.
Advantageous effects
1. The utility model discloses a strip vacuum adsorption pond holds paper edge and plays a roll, and adsorption area is big, and suction is full-purpose at the edge of paper, makes the difficult bounce-back of paper break away from.
2. The vacuum adsorption pond is bar-shaped structure, under the condition that does not influence vacuum adsorption effect, can adopt narrower opening, and the paper can not be inhaled the reentrant, has solved the problem of paper-back pipe difficulty.
3. Because each strip-shaped vacuum adsorption tank is communicated with the main vacuum chamber only through one small hole, when broken paper or paper shift deviation occurs in the area, the vacuum suction force is not greatly reduced, and a normal paper winding cylinder can be ensured.
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Fig. 3 is a partially enlarged view of fig. 2.
Fig. 4 is a schematic view of the working principle of the present invention.
Detailed Description
Referring to fig. 1-fig. 3, the utility model provides a vacuum drum shaft for a paper roll, including axle body 1, establish a plurality of bar vacuum adsorption ponds 3 that distribute along the axial on the surface of axle body 1, establish real empty room 5 in axle body 1, with the aperture 2 of real empty room 5 and vacuum adsorption pond 3 intercommunication, establish at the air flue 6 of axle body 1 one end and real empty room 5 intercommunication and establish the ring flange 4 at this end.
The working principle is as follows:
as shown in fig. 4, the roll paper a ' enters the reeling station after being glued by the glue spreading mechanism, the area of the front end of the roll paper a ' without glue spreading is positioned above the paper holding auxiliary roller b and the suspension shaft c, the roll paper a ' is pressed between the paper holding auxiliary roller b and the inner suspension shaft c by the shaft body 1, after the vacuum is switched on, vacuum is generated in the vacuum chamber 5 of the shaft body 1, the paper head a1 of the roll paper a ' is adsorbed by the vacuum adsorption tank 3 on the surface of the shaft body 1 to be fixed, the shaft body 1 rotates, and the roll paper a ' coated with glue is rolled into a paper cylinder under the combined action of the paper holding auxiliary roller b and the inner suspension shaft c.
Claims (2)
