[0025] As Figure 1-2 shown, an embodiment of the present utility model provides a paper suction device, which includes a main arm 312, a connecting plate 313, a plurality of suction cup assemblies, and a plurality of ion blower devices.

[0028] In this embodiment, the diagonal layout of the suction cup assembly and the ionized air blowing device can improve the stability and accuracy of paper picking.

The Bernoulli suction cup utilizes air flow to generate adsorption force, and in combination with the ionized air blowing device, it can reduce the problem of multiple sheets of paper being picked simultaneously during the paper picking process.

[0030] In a specific example, the suction cup assembly includes a suction cup holder 3150, a suction cup connecting frame 3151, a suction cup body 3152, and an air joint 3153.

[0031] Specifically, the suction cup holder 3150 is installed on the connecting plate 313; one end of the suction cup connecting frame 3151 is installed on the suction cup holder 3150 at a predetermined angle; one end of the suction cup body 3152 is installed on the suction cup connecting frame 3151, and the other end faces the designated position; one end of the air joint 3153 is connected to the suction cup body 3152, and the other end passes through the suction cup connecting frame 3151; the air joint 3153 is in communication with the suction cup body 3152; the other end of the air joint 3153 located in the first groove 320 sequentially passes through the suction cup connecting frame 3151 and the first connecting frame 317; one end of the first connecting frame 317 is connected to the suction cup connecting frame 3151, and the other end is connected to the ionized air blowing device.

Specifically, the first device plate 3170 is connected to the suction cup connecting frame 3151; one end of the second device plate 3171 is connected to the first device plate 3170, and the other end is provided with a first installation groove; the ion blowing device is installed in the first installation groove. By adjusting the relative positions of the suction cup assembly and the ion blowing device on the first connecting frame 317, different working conditions and paper characteristics can be adapted.

[0034] Preferably, the second connecting frame 318 includes a first plate 3180, a second plate 3181 and a third plate 3182. Specifically, one end of the first plate 3180 is connected to the connecting plate 313; the other end of the first plate 3180 is connected to one end of the second plate 3181; the third plate 3182 is connected to the other end of the second plate 3181; the third plate 3182 is provided with a second installation groove; the ion blowing device is installed in the second installation groove. By precisely controlling the installation position of the ion blowing device, the air flow can be managed and optimized more effectively to stabilize the paper and reduce the problem of multi-sheet adsorption during the adsorption process.

[0035] As a preferred embodiment, the second plate 3181 includes an L-shaped structure. It can be known to those skilled in the art that the shape of the second plate 3181 can be set according to actual needs, and can also include other structures besides the L-shaped structure.

[0036] In this embodiment, the paper suction device further includes a plurality of vacuum suction cups installed on the connecting plate 313. Specifically, the vacuum suction cups are connected to vacuum suction cup connectors 3143; the vacuum suction cup connectors 3143 pass through the connecting plate 313. The vacuum suction cups can provide more stable adsorption force to ensure the accurate grasping of the paper. It can also effectively solve the problem of adsorption deviation that is prone to occur when the Bernoulli suction cup has a high speed. In addition, the use of vacuum suction cups provides additional adsorption force, which can grasp the paper more stably, especially in the case of heavy or smooth-surfaced paper, improving the reliability of adsorption. It can also reduce physical damage to the paper and maintain the integrity and appearance quality of the paper.

[0037] Among them, the connecting plate 313 has an outer ring area and an inner ring area. Specifically, the inner ring area is located within the outer ring area; one set of the diagonal positions is located in the outer ring area, and the other set of the diagonal positions is located in the inner ring area; the plurality of suction cup assemblies include a first suction cup assembly 31500 and a second suction cup assembly 31510; the first suction cup assembly 31500 is installed in the first groove 320 located at one set of the diagonal positions; the second suction cup assembly 31510 is installed in the second groove 321 located at the other set of the diagonal positions; the plurality of ion wind blowing devices include a first ion wind blowing device 31600 and a second ion wind blowing device 31610; the plurality of first ion wind blowing devices 31600 are respectively arranged corresponding to the plurality of first suction cup assemblies 31500 and are located in the outer ring area; the plurality of second ion wind blowing devices 31610 are respectively arranged corresponding to the plurality of second suction cup assemblies 31510 and are located in the inner ring area; the plurality of vacuum suction cups include a first vacuum suction cup 3141 and a second vacuum suction cup 3142; the plurality of first vacuum suction cups 3141 are evenly distributed in the outer ring area, and the plurality of second vacuum suction cups 3142 are evenly distributed in the inner ring area.

[0038] In a specific example, when it is necessary to suck a smaller inner lining paper (usually the size of the inner lining paper is smaller than that of the box sealing paper), only need to first start the second suction cup assembly 31510 and the second ion wind blowing device 31610 located at the other set of diagonal positions and in the inner ring area, adsorb the inner lining paper on the second suction cup assembly 31510, then start the second vacuum suction cup 3142 located in the outer ring area to suck the inner lining paper, and then close the second suction cup assembly 31510 and the second ion wind blowing device 31610, so as to be able to suck the smaller paper. When it is necessary to suck a larger box sealing paper, only need to first start the first suction cup assembly 31500 and the first ion wind blowing device 31600 located at one set of diagonal positions and in the outer ring area, adsorb the box sealing paper on the first suction cup assembly 31500, then start the first vacuum suction cup 3141 located in the outer ring area to suck the box sealing paper, and then close the first suction cup assembly 31500 and the first ion wind blowing device 31600, so as to be able to suck the larger paper.

[0039] In addition, by evenly distributing the vacuum suction cups in the outer ring area and the inner ring area of the connecting plate 313, it can ensure that the adsorption force distribution on the paper is uniform, and avoid paper deformation or sliding caused by uneven adsorption force. The evenly distributed vacuum suction cups can also reduce the local pressure on the paper, thereby reducing the risk of damage to the paper during the adsorption process.

[0040] In this embodiment, the paper sucking device further includes a preheating device 319 installed on the main arm 312. Since there is an adhesive layer on the inner liner paper, the preheating device 319 can preheat the sucked inner liner paper to increase the viscosity of the adhesive layer, thereby improving the bonding effect between the inner liner paper and the nest box. Preheating the adhesive layer can reduce the time required for bonding, making the box sealing process faster and improving production efficiency.

[0041] Preferably, there are multiple preheating devices 319. Specifically, the multiple preheating devices 319 are respectively located on both sides of the connecting plate 313 and between the first groove 320 and the second groove 321. Arranging the preheating devices 319 on both sides of the connecting plate 313 can heat the adhesive layer more concentratedly, reduce heat dissipation, and improve energy efficiency.

[0042] In this embodiment, when the paper sucking device needs to suck the inner liner paper, when the suction cup assembly approaches the inner liner paper stack, start the suction cup assembly and the ion blowing device, and the suction cup assembly can suck the inner liner paper. After the inner liner paper is sucked, start the vacuum suction cup to suck (or grab) the inner liner paper, and then turn off the suction cup assembly (since the suction cup assembly is installed at a predetermined angle, in order to avoid the phenomenon that the paper is bent during the period before the vacuum suction cup sucks the paper and then lays it flat, resulting in the inability to lay the paper normally, the suction cup assembly can be turned off after the vacuum suction cup sucks the paper. If the above situation does not occur, it can also be selected to turn off when placing the paper on the nest box) and the ion blowing device, and the sucking (or grabbing) of the inner liner paper can be completed. When the paper sucking device needs to suck the box sealing paper, when the suction cup assembly approaches the box sealing paper stack, start the suction cup assembly and the ion blowing device, and the suction cup assembly can suck the box sealing paper. After the box sealing paper is sucked, start the vacuum suction cup to suck (or grab) the box sealing paper, and then turn off the suction cup assembly (since the suction cup assembly is installed at a predetermined angle, in order to avoid the phenomenon that the paper is bent during the period before the vacuum suction cup sucks the paper and then lays it flat, resulting in the inability to lay the paper normally, the suction cup assembly can be turned off after the vacuum suction cup sucks the paper. If the above situation does not occur, it can also be selected to turn off when placing the paper on the nest box) and the ion blowing device, and the sucking (or grabbing) of the box sealing paper can be completed.
