As shown in fig. 1 to 9, the full-automatic intelligent printing machine for replacing paper rollers comprises a paper roller support 1, a paper receiving workbench 2 and a gantry moving frame 3, a paper roll 11 and a paper storage roll 12 are installed on the paper roller support 1, a paper monitoring device 4 is installed on one side, close to the paper roller support 1, of the paper receiving workbench 2, the gantry moving frame 3 comprises support legs 31 and a cross beam 32, wherein the support legs 31 are located on two sides of the paper receiving workbench 2, the cross beam 32 is located between the two support legs 31, the two sides of the paper receiving workbench 2 are also provided with first sliding grooves 21 which are connected with the support legs 31 in a sliding mode, a paper clamping mechanism 5 is installed above the cross beam 32, a glue spraying mechanism 6 is installed on one side, close to the paper roller support 1, of the cross beam 32 is far away from the paper roller support 1, and a pressing roller mechanism 7 is installed on one side. The paper on the paper roll 11 is pulled by the printer body and enters the printer body through the surface of the paper receiving workbench 2 to be printed, when the paper monitoring device 4 monitors that the paper of the paper storage roll 12 is used up, the gantry moving frame 3 slides along the first sliding groove 21 in the direction away from the paper roller support 1 to drive the paper clamping mechanism 5 to pull the paper of the paper storage roll 12, meanwhile, the glue spraying mechanism 6 is driven to spray glue on the paper receiving workbench 2, then, the paper clamping mechanism 5 releases the paper on the paper storage roll 12 to complete the bonding of the paper, the gantry moving frame 3 slides in the direction close to the paper roller support 1 to drive the compression roller mechanism 7 to compact the bonded paper.
In one embodiment, a paper conveying mechanism of the printer body draws the paper on the running paper roll 11 to perform printing operation, a paper receiving table 2 is arranged between the printer and the running paper roll 11, and the paper passes through the surface of the paper receiving table 2 during conveying. A paper monitoring mechanism is arranged on one side of the paper receiving workbench 2 close to the operation paper roll 11 and can monitor whether paper exists or not. When the paper monitoring mechanism detects that no paper exists, the printing machine suspends the printing operation, and at the moment, the tail paper section of the operating paper roll 11 is distributed on the paper receiving workbench 2. Then, the gantry moving frame 3 moves towards one side far away from the paper roll support 1 along the first sliding groove 21 to drive the paper clamping mechanism 5 clamping the paper to pull the paper of the stored paper roll 12 to move towards one side far away from the paper roll support 1, and synchronously, when the gantry moving frame 3 moves to the middle area of the paper receiving workbench 2, the glue spraying mechanism 6 can spray glue on the tail paper section of the operation paper roll 11 on the paper receiving workbench 2. After the gantry moving frame 3 slides along the first sliding groove 21 to the side of the paper receiving workbench 2 far away from the paper roller bracket 1, the paper clamping mechanism 5 releases the clamped paper at the end part of the stored paper roll 12. With the loosening of the paper clamping mechanism 5, the paper at the end of the paper storage roll 12 descends to the paper receiving workbench 2 under the action of gravity to be bonded with the tail paper segment of the original running paper roll 11 on the paper receiving workbench 2. Subsequently, the pressure roller mechanism 7 on the gantry moving frame 3 rotates to a state of pressing the paper on the paper receiving worktable 2, the gantry moving frame 3 moves towards the direction close to the paper roller bracket 1 along the first sliding groove 21, and the paper pressing roller 76 of the pressure roller mechanism 7 rotates along the paper on the paper receiving worktable 2 along with the movement of the gantry moving frame 3, so that the paper of the operation paper roll 11 on the worktable is tightly adhered with the paper of the reserve paper roll 12. Finally, after the gantry moving frame 3 moves to the side of the paper receiving workbench 2 close to the paper roller bracket 1 along the first sliding groove 21, the press roller mechanism 7 rotates again to enable the paper pressing roller 76 to be separated from the paper on the paper receiving workbench 2, and the paper pressing roller 76 is prevented from influencing the conveying of the paper on the paper receiving workbench 2. The printing machine is started to drive the paper on the paper receiving workbench 2 into the printing machine, and then the paper of the reserve paper roll 12 continuously enters the printing machine under the action of the paper conveying mechanism of the printing machine main body to perform printing operation.
It should be noted that, because the paper monitoring device 4 is disposed at a side close to the operating paper roll 11, when the paper monitoring device 4 monitors that there is no paper at the paper monitoring device 4, the printer will immediately pause the printing operation, so as to ensure that the paper receiving table 2 has a tail paper segment of the operating paper roll 11 laid on most of the surface except the paper monitoring device 4. When the paper clamping mechanism 5 on the gantry moving frame 3 pulls the paper on the paper storage roll 12, the worker mounts the end of the paper on the paper storage roll 12 onto the paper clamping mechanism 5 in advance, so that the paper clamping mechanism 5 is in a state of clamping the paper, so as to pull the paper on the paper storage roll 12.
It should be noted that the glue spraying mechanism 6 only performs glue spraying operation in the area set in the middle of the paper receiving table 2 to ensure that the paper surface sprayed with glue is completely covered by the paper of the reserve paper roll 12, and to prevent the glue spraying area on the paper surface from not being completely covered by the paper of the reserve paper roll 12 and affecting the printing operation of the printing machine main body. That is, after the paper clamping mechanism 5 releases the clamped paper of the reserve paper roll 12, the end paper of the reserve paper roll 12 is affected by the position of the reserve paper roll 12 during the descending process, and the end of the paper can shift towards the reserve paper roll 12, so that the glue is sprayed only in the preset area in the middle of the paper receiving workbench 2, and the damage to the printing machine caused by the fact that the area where the paper is sprayed with the glue is not bonded by new paper is prevented. In one embodiment, the opening of the glue spraying mechanism 6 is controlled by a time controller, that is, the time taken for the gantry 3 to move from the side of the paper receiving table 2 close to the paper roller bracket 1 to the side far from the paper roller bracket 1 along the first sliding groove 21 is firstly calculated, then the time controller controls the glue spraying mechanism 6 to be opened after the gantry 3 moves to the set time of 3 seconds, and to be closed after the gantry 3 is opened for 10 seconds, and then the gantry 3 moves for 5 seconds again to reach the side of the paper receiving table 2 far from the paper roller bracket 1.
It should be noted that, when the gantry moving frame 3 drives the paper of the paper storage roll 12 to move to the side far away from the paper roll holder 1 along the first sliding groove 21, the press roll mechanism 7 is not in contact with the paper, and normal conveying of the paper is not affected. The gantry moving frame 3 drives the compression roller mechanism 7 to press the bonded paper, and meanwhile, the flattening effect on the paper can be achieved, so that tail paper of the paper roll 11 and end paper of the paper storage roll 12 which are operated on the paper receiving workbench 2 are both in a horizontal state, and the printer can conveniently pull the flattened paper. When the printer pulls the paper on the reserve roll 12, the paper will be in a tilted state and will not interfere with the entry of the paper on the reserve roll 12 into the printer.
Preferably, the paper clamping mechanism 5 includes a supporting block 51 fixed on the cross beam 32, an electromagnet 52 fixed on one side of the supporting block 51, and a magnet block 53 located right above the electromagnet 52, and the magnet block 53 is hinged to the supporting block 51 through a pin 54. The paper gripping mechanism 5 realizes a gripping operation of the paper by the electromagnet 52 and the magnet block 53.
Preferably, rubber pads 55 are fixed above the electromagnet 52 and below the magnet block 53. The rubber pad 55 contributes to clamping of the sheet by the sheet gripper mechanism 5, and prevents the sheet from being damaged by direct contact with the electromagnet 52 and the magnet block 53, and the frictional force generated between the rubber pad 55 and the sheet is larger than the frictional force generated between the magnet block 53 and the sheet, and contributes to pulling of the sheet.
Preferably, a vertically arranged limiting plate 56 protrudes above the supporting block 51, and an evenly distributed elastic protrusion 57 is fixed on one side of the limiting plate 56 close to the paper roller bracket 1, and the elastic protrusion 57 can prevent the magnet block 53 from being in a vertical state. The stopper plate 56 is used to restrict the rotation range of the magnet block 53 such that the rotation range of the magnet block 53 is restricted within a quarter circle. The elastic projection 57 serves to prevent the magnet block 53 from colliding with the stopper plate 56 and being damaged, while the elastic projection 57 has a tendency to prevent the magnet block 53 from being in a vertical state.
In one embodiment, when the worker installs the paper roll 12, the worker pulls out the end of the paper roll 12, as shown in fig. 4, places the paper on the rubber pad 55 above the electromagnet 52, and then energizes the electromagnet 52 to generate an attractive force between the electromagnet 52 and the magnet block 53, so that the magnet block 53 rotates along the pin 54 to the rubber pad 55 on the magnet block 53 to press the paper. Therefore, the sheet is clamped by the rubber pad 55 between the electromagnet 52 and the magnet block 53. Note that the thickness of the sheet shown in fig. 4 is shown to be large, and the thickness of the sheet shown in fig. 4 is shown to be thick in fig. 4 merely for illustrating the positional relationship.
In an embodiment, after the gantry moving frame 3 moves along the first sliding slot 21 to the side of the paper receiving table 2 away from the paper roll holder 1, when the paper clamping mechanism 5 needs to release the paper, the electromagnet 52 is energized in the opposite direction, and a repulsive force is generated between the electromagnet 52 and the magnet block 53, so that the magnet block 53 rotates along the pin 54 to a vertical state, and the paper at the end of the paper storage roll 12 slides down the paper clamping mechanism 5 under the action of gravity without being limited by the paper clamping mechanism 5.
In the preferred embodiment of the above embodiment, when the gantry 3 moves along the first sliding slot 21 to the side close to the paper receiving table 2 far from the paper roller support 1, the electromagnet 52 is energized in the opposite direction, and a repulsive force is generated between the electromagnet 52 and the magnet block 53, so that the magnet block 53 rotates along the pin 54 to a vertical state, and the paper at the end of the reserve paper roll 12 is not limited by the paper clamping mechanism 5, and the paper of the reserve paper roll 12 is more easily separated from the limitation of the paper clamping mechanism 5 along with the sliding of the gantry 3.
In an embodiment, when the electromagnet 52 is energized in the reverse direction, a repulsive force is generated between the magnet block 53 and the electromagnet 52, the magnet block 53 rotates along the pin 54 to a vertical state until colliding with the elastic protrusion 57 on the limiting plate 56, and the elastic protrusion 57 on the limiting plate 56 can prevent the limiting plate 56 from colliding with the magnet block 53 to damage the paper clamping mechanism 5. If the magnet block 53 is in the upright state, the electromagnet 52 will not affect the magnet block 53 when the electromagnet 52 is energized. Therefore, the limiting plate 56 is vertically disposed, and abuts against the limiting plate 56 when the magnet block 53 is in the vertical state, and the elastic protrusions 57 are uniformly distributed on the limiting plate 56, so that the elastic protrusions 57 have an effect of blocking the magnet block 53 from being in the vertical state on the magnet block 53, and therefore, when the electromagnet 52 is reversely energized, the magnet block 53 is in the inclined state, and the pressing force cannot be generated on the paper above the rubber pad 55 of the electromagnet 52. When the electromagnet 52 stops being energized, the magnet block 53 rotates downward along the pin 54 to the rubber pad 55 on the magnet block 53 to press the rubber pad 55 on the electromagnet 52 by gravity.
In a preferred mode of the above embodiment, the elastic protrusion 57 may be an elastic structure such as a spring 75, an elastic cushion, or the like.
Preferably, a second sliding groove 33 is formed on one side of the beam 32 close to the paper roll holder 1, and the glue spraying mechanism 6 is slidably connected with the second sliding groove 33. The glue-spraying mechanism 6 slides along the second sliding groove 33 to perform a glue-spraying operation on the paper in the paper width direction.
In an embodiment, the glue spraying mechanism 6 slides along the second sliding groove 33 to spray glue on the paper in the width direction, and the gantry moving frame 3 drives the glue spraying mechanism 6 to slide along the first sliding groove 21 to make the glue spraying mechanism 6 spray glue on the paper in the length direction, so that the glue spraying mechanism 6 can spray glue on an area on the surface of the paper.

When the platen roller 76 presses the paper while the gantry 3 slides along the first slide groove 21, rolling friction is generated between the platen roller 76 and the paper, that is, the platen roller 76 can rotate along the paper.
Preferably, the paper monitoring device 4 includes a motor base 41 fixed on the side wall of the paper receiving table 2, a motor 42 vertically arranged on the motor base 41, a supporting frame 43 connected with the motor 42, and an infrared emitter 44 located at the bottom of the supporting frame 43, an infrared receiver 45 is embedded in the paper receiving table 2, and the infrared receiver 45 is located right below the infrared emitter 44. The infrared emitter 44 cooperates with the infrared receiver 45 to enable monitoring for the presence of paper between the infrared emitter 44 and the infrared receiver 45. The motor 42 drives the supporting frame 43 to rotate to realize the adjustment of the position of the infrared emitter 44 fixed on the supporting frame 43, and prevent the supporting frame 43 and the infrared emitter 44 from influencing the adhesion between the paper sheets.
In an embodiment, the infrared emitter 44 sends an infrared signal to the infrared receiver 45, since the infrared receiver 45 is embedded inside the paper receiving table 2, and the paper is transported on the paper receiving table 2, the infrared receiver 45 cannot receive the infrared signal due to paper obstruction, when the paper running on the running paper roll 11 runs out, the paper cannot obstruct the infrared signal sent by the infrared emitter 44 from entering the infrared receiver 45, and the infrared receiver 45 receives the infrared signal to prove that the paper running on the running paper roll 11 runs out, so as to send a signal for suspending the printing operation to the printing machine. Since the supporting frame 43 and the infrared emitter 44 are located between the paper of the running paper roll 11 and the paper of the reserve paper roll 12, in order not to affect the adhesion of the paper, the motor 42 drives the supporting frame 43 to rotate around the axis of the motor 42, so that the supporting frame 43 and the infrared emitter 44 rotate to be separated from the table area of the paper receiving table 2.
Preferably, the paper roll stand 1 includes a first stand 13 supporting the reserve paper roll 12, a second stand 14 supporting the running paper roll 11, and a rotating stand 15 connecting the first stand 13 and the second stand 14, the rotating stand 15 enabling the first stand 13 and the second stand 14 to be interchanged. The first support 13 supports the reserve roll 12 and the second support 14 supports the operating roll 11, and the turning of the support 15 allows the first support 13 and the second support 14 to be interchanged for the installation of a new roll.
In one embodiment, when the operator finds that the printer is performing a print job using the reserve roll 12 on the first carriage 13 and the original running roll 11 on the second carriage 14 is depleted. The worker rotates the rotating bracket 15 to exchange the positions of the first bracket 13 and the second bracket 14, at this time, the stored paper roll 12 of the first bracket 13 originally becomes the operating paper roll 11, then a new stored paper roll 12 is additionally installed at the upper second bracket 14, the end paper of the new stored paper roll 12 is pulled out and is placed on the rubber pad 55 of the electromagnet 52 of the paper clamping mechanism 5, the electromagnet 52 is positively electrified, the electromagnet 52 and the magnet block 53 generate attraction, the magnet block 53 rotates around the pin shaft 54 to the rubber pad 55 on the magnet block 53 to press the paper, and the adding work of the new paper roll is completed.
It should be noted that, after the paper is adhered, the motor 42 of the paper monitoring device 4 drives the supporting frame 43 to rotate around the axis of the motor 42 to a state where the infrared emitter 44 is matched with the infrared receiver 45, at this time, the signal sent by the infrared emitter 44 is blocked again by the paper, the infrared receiver 45 cannot receive the infrared signal, and the printing machine continues to work. When the staff member does not add a new roll in time, the infrared receiver 45 sends a printing pause signal to the printing machine when the paper of the reserve roll 12 is used up. At this time, since the electromagnet 52 is still in the reverse current state, the gantry 3 cannot pull the paper by the paper gripping mechanism 5, that is, the gantry 3 does not respond, and the printing operation is suspended. Until the worker finds and adds a new paper roll, that is, the worker mounts the new paper roll to the paper gripping mechanism 5 and manually adjusts the electromagnet 52 to a forward energized state.
Preferably, the paper receiving table 2 is provided at both side corners thereof with rotating rollers 22 to be brought into contact with the paper. The turning roller 22 assists in the transport of the sheet over the splicing table 2.
