In the present embodiment, the paper splicing apparatus 10 includes: the device comprises a first guide roller 11, a first rotating arm 12, a first suction plate 13, a second suction plate 14 and a cutting and pasting mechanism 15.

Understandably, in the slitting rewinding of the rewinding machine, namely, in the process of sequentially slitting a large paper roll with a large width into a plurality of paper rolls with small standard vertebra specification widths through the rewinding machine, in order to ensure that the large paper roll arranged on the unwinding device 20 is sequentially unwound and conveyed to the winding device, the continuous operation can be realized, the splitting of one large paper roll is completed, and when the next large paper roll needs to be replaced, the joint and the tail end of the front large paper roll and the tail end of the rear large paper roll need to be bonded.
The rewinding machine generally comprises an unwinding device 20 and a winding device, wherein the unwinding device 20 is specifically used for installing and separating a large paper roll; and the coiling device is used for carrying out coiling operation again on a plurality of paper rolls which are separated and cut into standard vertebra specification width.
The unwinding device 20 and the winding device are usually large-scale apparatuses and installed on the ground, and the first guide roller 11 and the first rotating arm 12 in the paper receiving device 10 are sequentially disposed between the unwinding device 20 and the winding device at intervals in a first direction, and the first direction specifically refers to a horizontal direction from the unwinding device 20 to the winding device, so that the first roll 100 and the second roll 200 unwound from the unwinding device 20 can sequentially pass through the first guide roller 11 and the first rotating arm 12 and then are conveyed to the winding device.
Further, the first suction plate 13 and the second suction plate 14 are disposed in the first guide roller 11 in a second direction perpendicular to the first direction, that is, in a vertical direction perpendicular to the ground, at an interval, and when the paper ends 201 of the second paper roll sequentially unwound from the unwinding device 20 are conveyed to one side of the first suction plate 13, the first suction plate 13 can suck the paper ends 201 of the second paper roll. For example, in one embodiment, a plurality of suction holes are formed in parallel at intervals on one side of the first suction plate 13, and the suction holes are connected to a vacuum extractor through a hose, so that a negative pressure can be formed on one side of the first suction plate 13 through the vacuum extractor, and the paper head 201 of the second paper roll is continuously attached to one side of the first suction plate 13 until the vacuum extractor stops working; similarly, the second suction plate 14 can also form a negative pressure on one side of the second suction plate 14 by a vacuum device to suck the tail end 101 of the first paper roll tensioned by the winding device.
Understandably, the paper end 201 of the second paper roll refers to the end of the outermost end of the second paper roll 200, which is far away from the corresponding roll core; and the tail end 101 of the first roll refers to the end of the first roll 100 that is close to the end of the corresponding roll core.
The cutting and bonding mechanism 15 further includes a first platen 151 and a second platen 152, and an adhesive member 154 movably attached to the first platen 151 or the second platen 152 in a third direction, specifically, an extending direction of the first platen 151, and perpendicular to the first direction and the second direction.
The first paper pressing plate 151 and the second paper pressing plate 152 are disposed at an interval in parallel at one end of the first rotating arm 12 in a second direction, that is, in a vertical direction, and one end of the first rotating arm 12 can rotate in a direction approaching the first paper pressing plate 151 and the second paper pressing plate 152, so that the first paper pressing plate 151 and the second paper pressing plate 152 abut against the first suction plate 13 and the second suction plate 14, respectively. In one embodiment, a housing is further disposed at one end of the first rotating arm 12, and the first and second pressing plates 151 and 152 are disposed in the housing at a parallel interval, and the housing can rotate with one end of the first rotating arm 12 to approach the first and second pressing plates 151 and 152 to cover the first and second suction plates 13 and 14.
Wherein the adhesive member 154 can move in a third direction, i.e., in the extending direction of the first platen 151 and the second platen 152, from one end of the first platen 151 or the second platen 152 to the other end thereof to adhere the paper head 201 of the second paper roll and the tail end 101 of the first paper roll to each other. For example, in an embodiment, the adhesive assembly 154 can respectively attach a single-sided adhesive to two opposite sides of the paper head 201 of the second paper roll and the tail end 101 of the first paper roll, and two opposite sides of each single-sided adhesive are respectively attached to the paper head 201 of the second paper roll and the tail end 101 of the first paper roll and extend in the width direction of the second paper roll 200 and the first paper roll 100.
Therefore, the paper end 201 of the second paper roll and the tail end 101 of the first paper roll can be bonded with each other through each functional component of the paper receiving device 10, the situation that the paper end 201 of the second paper roll is spliced with the tail end 101 of the first paper roll is effectively avoided, the situation that a large amount of manpower is used for splicing the paper end is effectively avoided, the consumed time of the whole splicing process is greatly shortened, the production efficiency is improved, meanwhile, the problems that paper webs are folded, inclined or broken due to the use of the manpower are solved, the success rate of joint manufacturing is effectively improved, and the corresponding implementation cost is also reduced.
The splicing device 10 further includes a first vacuum-pumping assembly (not shown), a first conduit (not shown), and a second conduit (not shown), wherein opposite ends of the first conduit are respectively connected to the first vacuum-pumping assembly and the first suction plate 13, and opposite ends of the second conduit are respectively connected to the first vacuum-pumping assembly and the second suction plate 14. And a plurality of adsorption holes are respectively arranged on one side surfaces of the first suction plate 13 and the second suction plate 14 in parallel at intervals, and the first vacuum-pumping assembly can respectively form negative pressure on one side surfaces of the first suction plate 13 and the second suction plate 14 through the first conduit and the second conduit so as to adsorb the paper head 201 of the second paper roll and/or the tail end 101 of the first paper roll.
It can be understood that the vacuuming process of the first suction plate 13 and the second suction plate 14 by the first vacuum assembly through the first conduit and the second conduit is controlled independently, so that the first suction plate 13 and the second suction plate 14 can respectively and independently adsorb the paper head 201 of the second paper roll and/or the tail end 101 of the first paper roll according to the current actual requirement.
The paper receiving device 10 further includes a second rotating arm 16 and a paper receiving roller 17 connected to one end of the second rotating arm 16, and the other end of the second rotating arm 16 is specifically disposed on the ground between the unwinding device 20 and the first guide roller 11 at an interval.
And one end of the second rotating arm 16 can rotate towards a direction close to or away from the unwinding device 20, and when one end of the second rotating arm 16 is away from the unwinding device 20, the second rotating arm can be arranged between the first guide roller 11 and the first rotating arm 12 at intervals, so that when one end of the second rotating arm 16 is close to the unwinding device 20, the paper receiving roller 17 can absorb the paper head 201 of the second paper roll loaded on the unwinding device 20, and when one end of the first rotating arm 12 rotates towards a direction away from the unwinding device 20, the paper head 201 of the second paper roll is driven by the first rotating arm 12 to move towards the first absorbing plate 13, and is absorbed and fixed by the first absorbing plate 13.
Further, in an embodiment, the paper receiving roller 17 is specifically in a circular tube shape, and suction holes are formed in the side surface of the paper receiving roller 17 at intervals, the paper receiving device 10 further includes a second vacuum-pumping assembly (not shown) and a third conduit (not shown), and opposite ends of the third conduit are respectively connected to the second vacuum-pumping assembly and the paper receiving roller 17, so that when the paper receiving roller 17 abuts against the paper head 201 of the second paper roll on the unwinding device 20, a vacuum can be formed inside the paper receiving roller 17 through the third conduit, so that a negative pressure is formed on the outer side surface of the paper receiving roller 17, so as to suck the paper head 201 of the second paper roll, and drive the paper head 201 of the second paper roll to move to the first suction plate 13, and be sucked and fixed by the first suction plate 13.
Alternatively, the second vacuum assembly may be the same assembly as the first vacuum assembly, and the corresponding first conduit, second conduit and third conduit are each independently controlled by different control valves. In other embodiments, the second vacuum assembly may be a different assembly from the first vacuum assembly, which is not limited in this application.
It can be understood that, when the first roll 100 approaches the end of the unwinding, that is, the paper web on the roll core corresponding to the first roll 100 installed on the unwinding device 20 reaches the reserved remaining value, and the tail end 101 of the first roll is exposed, in order to ensure that the tail end 101 of the first roll can be effectively adsorbed on one side of the second suction plate 14 to achieve the adhesion with the paper head 201 of the second roll, when the first roll 100 is still tensioned between the unwinding device 20 and the winding device, the first roll 100 close to one side of the second suction plate 14 can be adsorbed, and the first roll 100 is cut from the gap between the first suction plate 13 and the second suction plate 14, so that the portion of the first roll 100 adsorbed on the second suction plate 14 is formed as the tail end 101 of the first roll, and the side facing the winding device is still tensioned by the winding device.
Specifically, the cutting and pasting mechanism 15 further comprises a cutting component 153, and the cutting component 153 is movably connected to the first paper pressing plate 151 or the second paper pressing plate 152 along the third direction to cut the first paper roll 100, so that the portion of the first paper roll 100 adsorbed on the second suction plate 14 is formed into the tail end 101 of the first paper roll.
Further, in order to ensure that the tail end 101 of the first paper roll can be spliced with the paper head 201 of the second paper roll, which is placed on the unwinding device 20 instead of the first paper roll 100, needs to be driven to the first suction plate 13, and is adsorbed and fixed by the first suction plate 13.
Specifically, the paper receiving roller 17 is rotatably connected to one end of the second rotating arm 16, so as to rotate in a direction approaching the unwinding device 20 at one end of the second rotating arm 16, and when the paper receiving roller 17 abuts against the paper head 201 of the second paper roll on the unwinding device 20, the paper receiving roller 17 can adsorb the paper head 201 of the second paper roll and rotate synchronously with the unwinding device 20, so as to roll part of the second paper roll 200.
Further, when one end of the first rotating arm 12 rotates in a direction away from the unwinding device 20 and a portion of the second roll 200 is disposed between the first guide roller 11 and the first rotating arm 12 at intervals, the first suction plate 13 can absorb a portion of the second roll 200 close to the first suction plate 13, and the cutting assembly 153 can move in the third direction, so that a portion of the second roll 200 absorbed on the first suction plate 13 is cut by a gap between the first suction plate 13 and the second suction plate 14, thereby forming the portion of the second roll 200 absorbed on the first suction plate 13 into a paper head 201 of a new second roll.
