[0002] Packaging cartons are made of paper products. Cartons have low costs, are easy to encapsulate, suitable for adding fillers, clean, etc., and are suitable for product factory packaging, item transportation, material sorting, etc.

[0003] Packaging cartons for item transportation or material sorting will be provided with grooves for grasping on both sides of the carton, and plastic handles will be installed in the grooves to facilitate the handling and transfer of the cartons. During the production process of such cartons, most of them will adopt a flat laying method, pressing the two grooves on a plane, installing the handles, and then collecting and bonding one side. However, due to the certain thickness of the handles, there will be a certain gap between the folded cartons during pressing, which may cause the bonding position to become loose, and even damage the handles during the pressing process. Summary of the Invention

[0004] The present invention discloses an automatic processing device for side handles of packaging cartons, aiming to solve the technical problem that due to the certain thickness of the handles, there will be a certain gap between the folded cartons during pressing, which may cause the bonding position to become loose, and even damage the handles during the pressing process.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic processing device for side handles of packaging cartons includes a transport table. On the opposite sides of the top of the transport table, limit side plates are respectively provided, and in the middle section of one of the limit side plates, a pressing side plate is provided. On one outer wall of the pressing side plate, an electric push rod is fixed, and one end of the electric push rod is fixedly connected to a bracket. On the same side outer wall of the pressing side plate, a plurality of limit rods are fixedly connected, and the plurality of limit rods are movably inserted into the bracket. A rotating mechanism is provided on the opposite side of the middle section of the transport table and the pressing side plate, and one side of the rotating mechanism is connected to a support table. On the top of the support table, a first pressing device is provided, and one side of the first pressing device is connected to a limit horizontal plate. On one side of the limit horizontal plate, a first conveying device is provided. At the opposite positions at the bottom of the support table, a second conveying device is simultaneously provided, and one side of the second conveying device is connected to a second pressing device. The first conveying device and the second conveying device are used for conveying handle accessories, and the support table, the first pressing device, and the second pressing device press and install the handle accessories through air rods. Guide mechanisms are respectively provided on one side of the transport table and one side of the first pressing device.

[0007] By providing an extrusion side plate and a support platform, when installing a buckle on a packaging carton that has been adhered on one side, the carton moves equidistantly at the top of the transportation platform and gradually moves to one side of the extrusion side plate. At this time, the electric push rod pushes the extrusion side plate, thereby reducing the width of the carton during the moving process, pushing one side of the carton to create a gap in the middle. At this time, under the action of the rotating mechanism, the front end of the support platform first enters the generated gap and completely enters the interior of the carton during the moving process, propping up the carton so that the carton completely sleeves on the support platform. At this time, the support platform, the first pressing device, and the second pressing device convey the required buckle accessories. After being conveyed to a specific position, they are extruded by a cylinder, thereby installing the four buckle accessories on the opposite sides of the carton, thus realizing three-dimensional installation and post-bonding installation. After installing the buckles, packaging can be directly carried out, avoiding the influence of bonding effect caused by installing the buckles after bonding.

[0008] In a preferred solution, a chute is provided on one side of the transportation platform, and the extrusion side plate is arranged in the chute. A first soft pressure strip is provided on one side of the transportation platform. A third conveying device is provided on one side of the transportation platform. The support platform includes two feeding ports, and the third conveying device can be respectively connected to the two feeding ports. The third conveying device is located on one side of the rotating mechanism. The rotating mechanism includes a bottom plate, and the bottom plate is fixed on one side of the transportation platform. A third support shaft is movably connected to the top of the bottom plate, and the top of the third support shaft is fixedly connected to a second gear. A motor is provided at the bottom of the bottom plate, and the motor is connected to the third support shaft. A groove is provided on the outer wall of one side of the second gear, and the second gear is movably engaged with a first gear. The bottom of the first gear is fixedly connected to a second support shaft, and the second support shaft is movably connected to the top of the bottom plate.

The limit ring is fixed on one side of the transportation platform. A circular support plate is fixed at the top of the first support shaft, and a connecting plate is provided on one side of the circular support plate. The connecting plate is connected to the support platform.

[0009] By providing a rotating mechanism, the motor slowly controls the second gear to drive the first gear to rotate, thereby driving the support platform to move to the top of the transportation platform to open the carton. After the operation is completed, the second gear rotates again. When the first gear contacts the groove position, under the action of the torsion spring, it quickly drives the support platform to return to its position and establish a connection with the third conveying device to complete the automatic feeding of the accessories. In this structure, the slow entry and fast exit of the support platform are completed, ensuring the stability of the accessories inside the support platform during transportation and also ensuring the quick withdrawal when separating from the carton.

[0010] In a preferred embodiment, the guiding mechanism includes a support housing and a plurality of second soft pressing strips.

[0011] By providing the guiding mechanism, after the cardboard box is installed with the lifting buckle, it disengages from the support table and continues to be conveyed forward along the transport table. During the conveying process, the top of the cardboard box is acted on by a plurality of second soft pressing strips to assist it in folding in the original folding direction. At the same time, under the action of a plurality of rollers moving inward, it always adheres to one side of the limiting side plate and moves, avoiding displacement during the movement. At the same time, when the support table rotates away from the cardboard box, the plurality of second soft pressing strips are first lifted. During the lifting process, the plurality of electrode sheets adhere to the outer wall of the support table, and under the action of the power generator, the static electricity on the support table is eliminated, thus ensuring the smooth progress of the step of the cardboard box disengaging.

On one side of the transport table 1 and one side of the first pressing device 4, guiding mechanisms 7 are respectively arranged. When installing the lifting buckles on a packaging carton that has been bonded on one side, the carton moves equidistantly on the top of the transport table 1 and gradually moves to one side of the extrusion side plate 13. At this time, the electric push rod 17 pushes the extrusion side plate 13, thereby reducing the width of the carton during the moving process, pushing one side of the carton to generate a gap in the middle. At this time, under the action of the rotating mechanism 10, the front end of the support table 6 first enters the generated gap and completely enters the inside of the carton during the moving process, propping up the carton so that the carton is completely sleeved on the support table 6. At this time, the required lifting buckle fittings are conveyed inside the support table 6, the first pressing device 4 and the second pressing device 9. After being conveyed to a specific position, they are extruded by a cylinder, so as to install the four lifting buckle fittings on the opposite sides of the carton, thus realizing three-dimensional installation and installation after bonding. After installing the lifting buckles, the packaging can be directly carried out, avoiding the influence of installing the lifting buckles and then bonding on the bonding effect.

The motor 109 slowly controls the second gear 112 to drive the first gear 105 to rotate, thereby driving the support table 6 to move to the top of the transport table 1 to open the carton. After the operation is completed, the second gear 112 rotates again. When the first gear 105 contacts the position of the groove 108, under the action of the torsion spring 107, the support table 6 is quickly driven to return to its position and establish a connection with the third conveying device 12, completing the automatic feeding of the accessories.

At the same time, under the action of the plurality of inwardly moving rollers 707, it always fits and moves along one side of the limiting side plate 3 to avoid displacement during the movement. At the same time, when the support table 6 rotates away from the carton, the plurality of second soft pressing strips 702 are first lifted. During the lifting process, the plurality of electrode plates 703 are attached to the outer wall of the support table 6, and the static electricity on the support table 6 is eliminated under the action of the power generator 701, so as to ensure the smooth progress of the carton detachment step.

[0029] Working principle: When installing the lifting buckle on a packaging carton that has been glued on one side, the carton moves equidistantly at the top of the transport table 1 and gradually moves to one side of the extrusion side plate 13. At this time, the electric push rod 17 pushes the extrusion side plate 13, thereby reducing the width of the carton during the movement, pushing one side of the carton to create a gap in the middle. At this time, the motor 109 slowly controls the second gear 112 to drive the first gear 105 to rotate, thereby driving the support table 6 to move to the top of the transport table 1. Its front end first enters the generated gap and completely enters the inside of the carton during the movement, propping up the carton so that the carton completely covers the support table 6. At this time, the support table 6, the first pressing device 4 and the second pressing device 9 convey the required lifting buckle accessories. After being conveyed to a specific position, they are squeezed by the cylinder, so as to install the four lifting buckle accessories on the opposite sides of the carton, thereby realizing three-dimensional installation and installation after gluing. After the lifting buckle is installed, the packaging can be directly carried out, avoiding the influence of installing the lifting buckle and then gluing on the gluing effect. After the lifting buckle is installed, the second gear 112 rotates again, and the first gear 105 contacts the groove 108 position. Under the action of the torsion spring 107, it quickly drives the support table 6 to return to its position and establish a connection with the third conveying device 12 to complete the automatic feeding of the accessories. In this structure, the slow entry and fast exit of the support table 6 are completed, ensuring the stability of the accessories inside the support table 6 during the transportation process and also ensuring the quick withdrawal when detaching from the carton. After the carton is installed with the lifting buckle, it disengages from the support table 6 and continues to be conveyed forward along the transport table 1. During the conveying process, the plurality of second soft pressing strips 702 act on the top of the carton to assist it to be folded in the original folding direction. At the same time, under the action of the plurality of inwardly moving rollers 707, it always fits and moves along one side of the limiting side plate 3 to avoid displacement during the movement. At the same time, when the support table 6 rotates away from the carton, the plurality of second soft pressing strips 702 are first lifted. During the lifting process, the plurality of electrode plates 703 are attached to the outer wall of the support table 6, and the static electricity on the support table 6 is eliminated under the action of the power generator 701, so as to ensure the smooth progress of the carton detachment step.
