In the initial state, the bevel gear spring 64 is in a compressed state, the limit bevel gear 67 and the driven bevel gear 63 are in a meshed state, and the reset torsion spring 69 is in a relaxed state.

The plastic package paper rolls are respectively placed on the upper and lower plastic package paper mounting shafts 21, the starting ends of the upper and lower plastic package paper rolls are pulled rightwards to the position between the upper and lower heating rods 24, the plastic package paper is clamped tightly through the heating rods 24 which are mutually abutted, and the paper to be plastic packaged is placed on the paper supporting plate 30.

The fixing plate adjusting shaft 33 is rotated to move the front and rear fixing plates 31 to push the paper to the center of the paper supporting plate 30, and the supporting wheel 11 abuts against the uppermost paper.

The starter motor 18 rotates the transition conveyor wheel shaft 16, thereby rotating the transition conveyor wheel 15 and simultaneously rotating the drive pulley 75, the driven pulley 76 and the intermediate belt 74 via the belt 73.

The intermediate transmission belt 74 rotates to drive the front driving gear shaft 61 to rotate, so that the front driving gear 70 rotates to drive the front driven gear 71, thereby driving the front adsorption wheel fixing block 56 to rotate, and further causing the adsorption nozzle fixing wheel 50 to rotate with the vent wheel 51 as the center, and then the adsorption nozzle fixing wheel 50 drives the rear adsorption wheel fixing block 56 to rotate, thereby driving the rear driving gear shaft 61 to rotate, and further causing the incomplete bevel gear 60 to rotate.

Because the incomplete bevel gear 60 can be meshed with the driven bevel gear 63 only by one rotation, that is, the incomplete bevel gear 60 can drive the driven bevel gear 63 to rotate by a certain angle only by one rotation.

At this time, the air pump 59 is started to suck air inwards by the air pump 59, so that the air suction chamber 57 sucks air inwards, so that the air shaft 53 sucks air inwards through the air outlet chamber 52, and further, the air wheel 51 sucks air inwards through the fan-shaped air cavity 510, so that the adsorption nozzle 54 located on one side of the fan-shaped air cavity 510 sucks air inwards, and accordingly, the uppermost paper is adsorbed to the adsorption nozzle 54 on the left and right of the suction force of the adsorption nozzle 54.

Meanwhile, the adsorption nozzle fixing wheel 50 rotates to drive the adsorption nozzle 54 to rotate, so that the adsorption nozzle 54 conveys adsorbed paper to the right onto the supporting plate 25, and then the paper moves to the right into the plastic packaging cavity 27 through the rotating transition conveying wheel shaft 16.

At this time, the heating rod 24 is started to heat the heating rod 24, so that the plastic packaging paper passing through the space between the upper and lower heating rods 24 is bonded together, and when the paper to be plastic packaged moves to the heating rod 24 rightwards, the paper to be plastic packaged is plastic packaged together by the plastic packaging paper.

After the uppermost paper to be subjected to plastic packaging is completely packaged in the plastic packaging cavity 27, the number of rotating turns of the incomplete bevel gear 60 just reaches one turn of the driven bevel gear 63, and the driven bevel gear 63 rotates to drive the screw shaft 41 to rotate, so that the paper supporting plate 30 moves upwards by the height of one paper thickness, the uppermost paper is always kept the same as the distance between the lowermost adsorption nozzles 54, and the lowermost adsorption nozzles 54 can adsorb the paper all the time.

In the process of rotation of the driven bevel gear 63, the screw shaft 41 rotates to drive the reset torsion spring 69 to twist and accumulate force, the driven bevel gear 63 rotates to drive the limit bevel gear 67 to rotate, the limit bevel gear 67 does not drive the limit bevel gear shaft 65 to rotate due to the action of the one-way bearing 68, when the incomplete bevel gear 60 is disengaged from the driven bevel gear 63, the screw shaft 41 tends to reverse under the action of the torsion of the reset torsion spring 69, the driven bevel gear 63 also tends to reverse, so that the limit bevel gear 67 tends to reverse, the limit bevel gear shaft 65 is driven to reverse due to the reverse rotation of the limit bevel gear 67 due to the action of the one-way bearing 68, the limit bevel gear shaft 65 is in spline fit with the rear end wall of the bevel gear transmission cavity 62, so that the limit bevel gear shaft 65 cannot rotate, and when the incomplete bevel gear 60 is disengaged from the driven bevel gear 63, the driven bevel gear 63 remains in a stationary state.

The movement process is repeated continuously, so that the purpose of continuously and automatically feeding and packaging paper to be packaged is achieved.

If the plastic package of the plastic package paper is completed, the air pump 59 and the motor 18 are turned off, the incomplete bevel gear 60 stops rotating, at this time, the limit bevel gear shaft 65 is pulled backwards, the one-way bearing seat 66 overcomes the elastic force of the bevel gear spring 64 to move backwards, the one-way bearing 68 is made to move backwards, the limit bevel gear 67 is made to move backwards to be disengaged from the driven bevel gear 63, the screw shaft 41 is made to rotate reversely under the torsion action of the reset torsion spring 69, the paper support plate 30 is driven to move downwards to the initial position, and the device returns to the initial state.

The invention has the beneficial effects that: the paper to be plastic-sealed is adsorbed by the adsorption mechanism and is rotated, so that the paper is fed one by one uninterruptedly, manual feeding is replaced, labor consumption is reduced, the same space of plastic sealing of the paper is ensured, subsequent cutting work is greatly facilitated, meanwhile, the paper supporting plate for lifting the paper to be plastic-sealed can be continuously lifted along with the plastic sealing process, a certain distance is always kept between a paper pile to be plastic-sealed and the adsorption nozzle, and the paper can be smoothly adsorbed by the adsorption nozzle.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
