Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, specifically a recycling device for single-layer paper boxes after gluing. Background Technology

[0002] Single-layer cardboard boxes, made from a single layer of corrugated paper or kraft paper, are folded and formed after cutting and creasing. They are common lightweight packaging containers in the fields of daily necessities, food, and small commodities. They are simple in structure and low in cost, but their load-bearing and tear resistance are limited. Therefore, the gluing process is crucial. Applying environmentally friendly glue evenly to the seams of the cardboard box can not only strengthen the box structure and prevent deformation and cracking during transportation or use, but also form a sealing layer to block moisture and dust, extending the shelf life of the contents. Modern automated gluing technology has significantly improved production efficiency and ensured that the glue layer is uniform and stable. Although gluing adds a process, it is indispensable for improving the practicality and protective performance of the cardboard box. However, the recycling and subsequent assembly of the cardboard box after gluing still face challenges: the peelability of the glue needs to be optimized to facilitate the separation and recycling of the cardboard, and the degree of automation in assembly needs to be improved to adapt to the material characteristics after gluing. These aspects directly affect environmental benefits and production efficiency. There may be existing technical solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a single-layer cardboard box recycling device after gluing, comprising: a device base, a displacement top platform, and a pair of top platform mounting flanges, wherein the pair of top platform mounting flanges are respectively installed on the displacement top platform; a pneumatic conveying structure is installed on the device base; and a collaborative auxiliary moving structure is installed on the displacement top platform; the collaborative auxiliary moving structure comprises: an electric slide rail, an electric slider, an electric telescopic rod, a connecting adsorption block, a negative pressure air pump, an adsorption jelly layer, and a negative pressure air collection tank;

[0004] The electric slide rail is installed on the displacement top platform, the electric slider is installed on the electric slide rail, the electric telescopic rod is installed on the electric slider, the connecting adsorption block is installed on the electric telescopic rod, the negative pressure air pump is installed on the connecting adsorption block, the adsorption jelly layer is installed on the connecting adsorption block, and the adsorption jelly layer is provided with the negative pressure air collection groove, which is connected to the negative pressure air pump;

[0005] It should be noted that, as described above, the cardboard box blank after being coated with glue is placed on the device base through the branch blower nozzle. A pair of top platform mounting flanges stably place the displacement top platform on the ceiling. The electric telescopic rod is driven to extend, causing the adsorbed jelly layer to adhere to the cardboard box blank placed on multiple safety weight hubs. The negative pressure air pump connected to the adsorption block is driven to create a vacuum negative pressure at the negative pressure collection groove, gently lifting the cardboard box blank. At the same time, the good wind power conveying structure also provides a certain support force upward. Then, the electric slider is driven to slide on the electric slide rail, finally transporting the glued cardboard box blank to the electric transport platform. The emergency stop button on the device base can stop the device in an emergency to prevent production accidents.

[0006] Preferably, the good air power conveying structure includes: a blower pump, an internal air duct, several branch blowers, a central heating layer, an air filter plate, several safety weight hubs, a connecting slide, a pair of supporting slide rails, several rail ball bearings, an electric transport platform, several support bases, and several supporting legs.

[0007] The blower pump is installed on the device base, the internal air duct is installed inside the device base, the blower pump is connected to the internal air duct, several branch blowers are respectively installed on the internal air duct, the central heating layer is installed inside the device base, the air filter plate is installed on the device base, several safety weight hubs are respectively installed on the device base via rotating shafts, the connecting slide is connected to the device base, a pair of supporting slides are respectively installed on the connecting slide, several rail ball bearings are respectively installed on the pair of supporting slides, the electric transport platform is connected to the connecting slide, several support bases are respectively installed on the electric transport platform, and several supporting legs are respectively installed on several support bases;

[0008] It should be noted that, as described above, when the cardboard box blank is placed on the multiple safety weight hubs on the device base, the adsorption jelly layer, in conjunction with the negative pressure air collection groove, will appropriately adsorb and lift the cardboard box blank upwards. Simultaneously, the blower pump operates, blowing high-pressure air into the internal air duct. This high-pressure air is sprayed from multiple branch blowers towards the central heating layer above. The central heating layer generates a certain degree of high temperature. The heated air then passes through a filter plate and is blown upwards. At this point, the glued cardboard box blank will adhere securely to the adsorption jelly layer. Because the glued side of the cardboard box blank is heated by the hot air from the central heating layer, the glue is less likely to melt and drips, ensuring better adhesion of the glue to the cardboard box blank. Until it is transported to the connecting slide, the cardboard box blank is released from the adsorption jelly layer. The cardboard box blank falls onto a pair of supporting slide rails. The blank, supported by multiple ball bearings on the rails, slides downwards onto a motorized transport platform. Simultaneously, the motorized transport platform operates, driving multiple supporting legs and their bases to move continuously until it reaches the processing side. The cardboard box blank sliding on the rails then lands securely on the supporting legs, where it is further supported by the supporting legs on the bases. This facilitates subsequent processing of the glued cardboard box blank by workers. The ceramic anti-friction layer on the ball bearings effectively prevents the glue layer from adhering to the ball bearings. The fluorinated anti-stick layer on the safety scale wheel hub also prevents the cardboard box blank from adhering to the hub if it lands on it.

[0009] Preferably, the device base is provided with a maintenance and inspection port;

[0010] Preferably, the track ball bearing is provided with a ceramic friction-reducing layer;

[0011] Preferably, the hub of the safety scale weight is provided with a fluorinated anti-stick layer;

[0012] Preferably, an emergency stop button is provided on the base of the device.

[0013] Beneficial effects

[0014] This utility model provides a single-layer cardboard box post-coating recycling device. It offers the following advantages: Compared with existing technologies, this single-layer cardboard box post-coating recycling device achieves efficient transfer of coated cardboard box blanks between the conveyor belt and the coating workshop through the coordinated operation of a collaborative auxiliary transfer structure and a pneumatic conveying structure. The system innovatively integrates dynamic handling and drying processes, allowing the cardboard box blanks to complete the curing process simultaneously during round-trip transportation, eliminating the need for additional stops to wait for drying and significantly shortening the production cycle. This streamlined design not only ensures the stability of material transmission but also maximizes the utilization of time resources through process layering, thereby effectively improving overall production efficiency.

Several safety weight hubs 16. Connecting slide 17. A pair of supporting slide rails 18. Several rail-mounted ball bearings 19. Electric transport platform 20. Several support bases 21 and several supporting legs 22; The blower pump 11 is installed on the device base 1, the internal air duct 12 is installed inside the device base 1, the blower pump 11 is connected to the internal air duct 12, several branch blower nozzles 13 are respectively installed on the internal air duct 12, the central heating layer 14 is installed inside the device base 1, and the air filter plate 15 is installed. On the device base 1, several safety weight hubs 16 are respectively mounted on the device base 1 via rotating shafts. The connecting slide 17 is connected to the device base 1. A pair of supporting slide rails 18 are respectively mounted on the connecting slide 17. Several rail ball bearings 19 are respectively mounted on the pair of supporting slide rails 18. The electric transport platform 20 is connected to the connecting slide 17. Several support bases 21 are respectively mounted on the electric transport platform 20. Several supporting legs 22 are respectively mounted on several support bases 21.

[0024] According to the appendix Figure 1-4It is found that after the cardboard box blank is coated with glue, it is placed on the device base 1 through the branch blower nozzle 13. A pair of top platform mounting flanges 3 stably place the displacement top platform 2 on the ceiling. The electric telescopic rod 6 is driven to extend so that the adsorbent jelly layer 9 is in contact with the cardboard box blank placed on multiple safety weight hubs 16. The negative pressure air pump 8 on the connecting adsorption block 7 is driven to form a vacuum negative pressure at the negative pressure collection groove 10, which gently lifts the cardboard box blank. At the same time, the good wind power conveying structure also provides a certain support force upward. Then, the electric slider 5 is driven to slide on the electric slide rail 4, and finally the glued cardboard box blank is transported to the electric transport platform 20. The emergency stop button on base 1 can stop the device in an emergency to prevent production accidents. When the cardboard blank is placed on the multiple safety weight hubs 16 on the device base 1, the adsorption jelly layer 9, in conjunction with the negative pressure air collection groove 10, will appropriately adsorb and lift the cardboard blank upwards.

The cardboard box blank will be securely attached to the absorbent jelly layer 9. The side of the cardboard box blank coated with glue is heated by the hot air from the central heating layer 14, making the glue less likely to melt and drip, ensuring better adhesion to the cardboard box blank. Until it is transported to the connecting slide 17, the cardboard box blank is released from the absorbent jelly layer 9 and falls onto a pair of supporting slide rails 18.
