Detailed Description
Example 1
The paper roll sealing device of this embodiment includes, as shown in fig. 1, an unreeling mechanism composed of a first upper endless belt 1 and a first lower endless belt 2, the first upper endless belt 1 and the first lower endless belt 2 being capable of sandwiching a paper roll 3 together. The travelling direction of the portion of the first upper belt 1 in contact with the paper roll 3 is opposite to the travelling direction of the portion of the first lower belt 2 in contact with the paper roll 3. When the traveling speed of the first upper endless belt 1 is greater than the traveling speed of the first lower endless belt 2, the paper roll 3 can be driven to roll from one end of the first lower endless belt 2 to the other end as shown in fig. 1 to 2. When the traveling speed of the first upper endless belt 1 is equal to the traveling speed of the first lower endless belt 2, as shown in fig. 3, the roll 3 of paper can be rotated in place and a piece of paper can be discharged from the trailing end of the roll 3 of paper. In order to make it easier to pay out the tail end of the roll 3, the unreeling mechanism is further provided with a blower 4, as shown in fig. 2, which blows towards the tail end of the roll 3, separating the tail end of the roll 3 from the cylindrical surface of the roll 3.
The paper roll sealing device is provided with a gap 5. The slit 5 may be provided in the frame of the roll closing device. As shown in fig. 3, the sheet 6 discharged from the roll 3 by the unreeling mechanism may cover the seam of the slit 5. An electric eye 7 can be used to detect the length of paper 6 paid out. The paper roll sealing device is also provided with a slotting tool 8, and the slotting tool 8 is in a flake shape. As shown in fig. 4, the cutter 8 can push the paper covered on the slit into the slit 5, so that the paper is bent at the front edge of the cutter 8 to form two opposite side papers 6a, 6b. As the slotting tool 8 goes deep into the gap 5, as shown in fig. 5, the front edge of the slotting tool 8 can cut the two side papers 6a, 6b at the bending position.
In order to accurately control the timing of cutting the paper by the cutter 8, a pressing member 9 for pressing the paper is provided outside the slit 5. When the sheet pressed into the slit 5 has not reached a sufficient depth, as shown in fig. 4, the pressing member 9 does not press the sheet, and the slotting tool 8 only plays a role of pressing the sheet into the slit 5 and does not cut the sheet; when the sheet pushed into the slit 5 reaches a sufficient depth and the sheet needs to be cut by the cutter 8, as shown in fig. 5, the pressing members 9 press the sheet on both sides of the slit 5, so that the sheet is stationary, and the cutter 8 can cut the sheet. The plunger 8 and the pressing member 9 may be driven by a conventional to moving member such as an air cylinder, a hydraulic cylinder, a motor, or the like. An electric eye 10 can be used to detect the depth of the paper being pressed into the slot 5.
The paper roll sealing device is also provided with a first pressing mechanism. The first pressing mechanism includes a first pressing block 11 driven to act by a conventional to moving member such as an air cylinder, a hydraulic cylinder, a motor, or the like. As shown in fig. 7, the first presser 11 applies pressure to the broken two-sided sheet, and the two-sided sheet is pressed together. The first presser 11 may be a roller, and the first presser 11 rolls in parallel with the axial direction of the paper roll 3 while pressing one side of the paper when the first presser 11 applies pressure to the paper.
In order to avoid unnecessary movement of the two side sheets 6a, 6b before the press-fit is integrated, a suction device 12 is provided at a position close to the first press-fit mechanism. As shown in fig. 6, when the two-sided paper is broken and the slotting cutter 8 is pulled out of the slot 5, the broken two-sided paper is pressed and fixed by the aspirator 12 at a position that can be pressed by the first pressing mechanism. The aspirator 12 may be an aspiration hole opened on a sidewall of the slit 5.
The paper roll sealing device is also provided with a winding mechanism. The winding mechanism and the unwinding mechanism of the present embodiment are the same mechanism, and are also composed of a first upper endless belt 1 and a first lower endless belt 2. After the first pressing mechanism presses the both side sheets 6a, 6b in the slit 5 into one body, the first upper circulating belt 1 and the first lower circulating belt 2 travel in the direction opposite to the unreeling step, and the paper roll 3 is rotated in place in the direction opposite to the unreeling step, so that the released piece of paper is rewound onto the paper roll 3 as shown in fig. 8.
The paper roll sealing device is also provided with a second pressing mechanism. The second pressing mechanism comprises a second pressing block 13 which is driven to act by a conventional moving part such as an air cylinder, a hydraulic cylinder, a motor and the like. As shown in fig. 9, the end of the sheet wound up on the paper roll 3 is pressed into one body by the second pressing block 13 together with the both side sheets which have been previously pressed into one body. The second presser 13 may be a roller, and the second presser 13 rolls in parallel with the axial direction of the paper roll 3 while pressing the paper one side when the second presser 13 applies pressure to the end of the paper.
The roll sealing method of the present invention will be described below with reference to the roll sealing device of the present embodiment. Firstly, as shown in fig. 2 to 3, a piece of paper 6 is discharged from the tail end of the paper roll 3, then, as shown in fig. 4 to 5, at a position at a certain distance from the end of the discharged piece of paper 6, the paper is extruded into the gap 5 by a slotting cutter 8, the paper is bent at the front end cutting edge of the slotting cutter 8 to form two opposite side paper 6a and 6b, the paper is cut at the bending position by the front end cutting edge of the slotting cutter 8, then, the two opposite side paper is pressed into a whole as shown in fig. 7, then, the previously discharged piece of paper is rewound onto the paper roll 3 as shown in fig. 8, and then, the end of the paper and the two side paper which are pressed into a whole before are pressed into a whole together as shown in fig. 9, so that the sealing of the paper roll 3 is completed. After the sealing is completed, the rolls can be fed out by means of the conveyor belt 14 and the conveyor belt 15.
Example two
The paper roll sealing device of this embodiment is shown in fig. 10. In the drawings of the present embodiment, the same reference numerals as those of the first embodiment denote the same structures, and these structures have the same operation principle and function as those of the first embodiment. The difference between the present embodiment and the first embodiment is a winding mechanism and a second pressing mechanism. The winding mechanism of this embodiment is composed of a second upper endless belt 16 and a second lower endless belt 17. The second upper endless belt 16 and the second lower endless belt 17 may clamp the paper roll 3 together. The travelling direction of the portion of the second upper belt 16 in contact with the paper roll 3 is opposite to the travelling direction of the portion of the second lower belt 17 in contact with the paper roll 3. As shown in fig. 11, when the two opposite sides of the paper in the gap 5 are pressed together by the first pressing block 11 of the first pressing mechanism, the travelling speed of the second upper circulation belt 16 is greater than that of the second lower circulation belt 17, so that the paper roll 3 is driven to roll from the position shown in fig. 11 to the position shown in fig. 12, and the paper roll 3 completes the winding process of rewinding the previously released paper into the paper roll 3 during the rolling process.
The second press-fit mechanism of this embodiment is located near the end of the second lower endless belt 17. The second press-fit mechanism includes a pendulum 18 driven by a conventional to moving member such as a cylinder, hydraulic cylinder, motor, etc. When the pendulum 18 rotates about the shaft 19, as shown in fig. 13, the end of the sheet wound on the paper roll 3 is pressed by the pendulum 18 into one body together with the two side sheets which have been previously pressed into one body.
The paper roll sealing method implemented in this embodiment is the same as that in the first embodiment.
Example III
The paper roll sealing device of this embodiment is shown in fig. 14. In the drawings of the present embodiment, the same reference numerals as those of the first and second embodiments denote the same structures, and these structures have the same operational principles and functional roles as those of the first and second embodiments. The present embodiment differs from the first and second embodiments in that the slit 5 is constituted by two rotating rollers 20, 21 which are close to each other, one of the rotating rollers 20 being a driving roller of the first lower endless belt 2, the other rotating roller 21 being a driving roller of the second lower endless belt 17, and the other rotating roller 21 being provided with a suction hole 22, the suction hole 22 rotating together with the rotating roller 21 and sucking air only at a position rotated to be close to the slit 5. During insertion of the slotting tool 8 into the slot 5, as shown in fig. 14-15, the two rotating rollers 20, 21 rotate in the direction shown in the drawings, thereby helping the slotting tool 8 to push the paper covered at the seam of the slot 5 into the slot 5.
In order to adjust the width of the gap 5, the second lower circulation belt 17 and the rotating roller 21 can be arranged on a sliding mechanism, and the sliding mechanism drives the second lower circulation belt 17 to integrally move together with the rotating roller 21, so that the gap between the two rotating rollers 20 and 21 can be adjusted.
The paper roll sealing method implemented in this embodiment is the same as that in the first embodiment.
Example IV
The paper roll sealing device of this embodiment is shown in fig. 16. In the drawings of the present embodiment, the same reference numerals as those of the first, second, and third embodiments denote the same structures, and these structures have the same operation principle and function as those of the first, second, and third embodiments. The difference between this embodiment and the first, second and third embodiments is that the first and second pressing mechanisms are the same pressing mechanism, and the pressing mechanism is provided with a pressing block 23 driven to move by a normal driving member such as an air cylinder, a hydraulic cylinder, a motor, etc. After the slotting tool 8 completes the actions shown in fig. 17 to 18, cuts the paper and forms the opposite two-sided paper 6a, 6b between the two rotating rollers 20, 21, as shown in fig. 19, the two-sided paper that has been cut is pressed into a whole by the pressing block 23, thus realizing the function of the first pressing mechanism in the foregoing embodiment; when the paper sheet discharged from the roll is rewound into the roll, as shown in fig. 20, the end of the paper sheet wound onto the roll 3 is pressed by the pressing block 23 into one body together with the two side paper sheets which have been previously pressed into one body, thus realizing the function of the second pressing mechanism in the foregoing embodiment. The press block 23 may be a roller, and the press block 23 rolls in parallel with the axial direction of the paper roll 3 while pressing one side of the paper when the press block 23 applies pressure to the paper.
The paper roll sealing method implemented in this embodiment is the same as that in the first embodiment.
