[0026] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0028] Combine Figure 1-8 As shown, a folding device of an automatic carton forming machine includes:

[0029] The box body 1 is the outer shell of the entire processing equipment, which is mainly used to assist in fixing various components. There are openings 11 on the left and right sides of the box body, and conveyor belts for conveying cardboard are arranged at the openings 11;

[0030] Calibration table 2, used to calibrate and position the cardboard for rapid processing;

[0031] The folding plate 3 is arranged on the top surface of the calibration table 2, and forces the cardboard to turn synchronously by turning it over, and finally completes the bonding of the cardboard ends so that it can be unfolded into a rectangular structure after passing this process;

[0032] The cutting assembly 5 has a laser cutting head 54 connected to its bottom end, and can drive the laser cutting head 54 to move in space along the X, Y and Z axes so as to adjust the cutting depth and position of the cardboard.

[0033] Specifically; in this embodiment, the calibration platform 2 is configured to be rectangular and fixedly installed on the inner bottom surface of the box body 1. The top surface of the calibration platform 2 is provided with four slide grooves 21. The ends of the four slide grooves 21 are all close to the center direction, so that the four slide grooves 21 are arranged in a circular array around the center of the calibration platform 2.

[0034] On the four slide grooves 21, each slide groove 21 is provided with a slider 22 inside. The end of the slider 22 is detachably fixedly connected to a holder 23. The holder 23 is an L-shaped structure, which is used to clamp and fix the four corners of the cardboard and achieve the effect of rapid proofreading.

[0035] The bottom of each slider 22 is protruding and extends downward along the inner wall of the slide 21 to the interior of the calibration table 2. The interior of the calibration table 2 is hollow, and an adjusting disk 25 is rotatably installed at the center. The top surface of the adjusting disk 25 is provided with a vortex-shaped groove, and the protruding part of the slider 22 is movably inserted into the groove. At the same time, a transmission shaft is also provided at the bottom of the adjusting disk 25. A first servo motor 12 is provided at the bottom of the box body 1, and the output end of the first servo motor 12 is just connected to the end of the transmission shaft. Therefore, when the servo motor rotates forward, the slider 22 is moved toward the center distance, and the four L-shaped holders 23 respectively abut the ends of the cardboard, so that the cardboard is arranged concentrically with the calibration table 2, and finally cooperates with the cutting assembly 5 to complete the cutting. When the servo motor reverses, since the four holders 23 are tilted outward, they can be expanded to a width wider than the opening 11 of the box body 1, thereby avoiding the problem that the cardboard cannot be normally transported to the interior.

[0036] In the above structure, in order to prevent the cardboard corners from being rubbed and squeezed to breakage due to excessive clamping force of the cardboard holder 23 or being pushed, a layer of elastic pad should be appropriately provided on the inner wall of the cardboard holder 23 .

[0037] In addition, the calibration platform 2 is provided with a mounting groove 24, the end of which is provided with a hinged seat, and a connecting shaft 31 is longitudinally arranged between the two hinged seats. The folding plate 3 is just embedded in the mounting groove 24 and its end is fixedly connected to the connecting shaft 31. An electric motor for driving the connecting shaft 31 to rotate is also provided on the outer wall of the calibration platform 2.

[0038] A connecting portion is also provided at the end of the folding plate 3. The connecting portion is arranged in a rectangular shape with a through hole in the center. An adhesive plate 4 is arranged at intervals toward the connecting portion of the folding plate 3. Both ends of the adhesive plate 4 extend outward and are movably inserted into the through hole. The extended portion should be arranged in a cylindrical shape and a toothed portion is provided on its outer side wall. A driving gear 32 is correspondingly provided on the end face of the folding plate 3. The driving gear 32 is engaged with the toothed portion, and a second servo motor is also provided inside the folding plate 3. The output end of the second servo motor is fixedly connected to the center of the driving gear 32.

[0039] The interior of the adhesive plate 4 is also hollow and contains adhesive. A spray hole 41 is provided on the back of the adhesive plate 4 .

[0040] The cutting assembly 5 includes a slide rail arranged horizontally at the top of the box body 1, a mounting seat 52 is provided on the slide rail, a cylinder 51 is vertically provided at the bottom of the mounting seat 52, and a laser cutting head 54 is fixedly mounted on the bottom end of the cylinder 51.

[0041] At the same time, a guide groove 53 is provided on the inner side wall of the top of the box body 1, in which a lead screw is rotated in one of the guide grooves 53, and both ends of the slide rail are respectively inserted into the guide groove 53, and one section is assembled with the lead screw thread. The outside of the box body 1 is also equipped with a motor for driving the lead screw to rotate, and the inside of the mounting seat 52 should also be equipped with an electric wheel adapted to the slide rail, so as to achieve a three-coordinate displacement effect of the laser cutting head 54 through the three driving structures of the cylinder 51, the mounting seat 52 and the lead screw.

[0042] In the above structure, the processing steps of the cardboard are:

[0043] 1. The conveyor belt transports the cardboard into the box body 1. The first servo motor 12 starts working, driving the four cardboard holders 23 to gather toward the center through the adjustment disk 25, and making them respectively contact the four corners of the cardboard to complete the initial fixing effect;

[0044] 2. After fixing, the cutting component 5 starts working, quickly cutting the cardboard through three-coordinate displacement, and performing partial cutting according to the actual folding required. After cutting, it moves to a safe position;

[0045] 3. The electric motor drives the folding plate 3 to flip, so that it forms an obtuse angle greater than 90° with the surface of the calibration table 2 and remains fixed;

[0046] 4. The second servo motor starts, and causes the adhesive plate 4 to completely adhere the portion of the cardboard to be bonded to the side wall of the cardboard. Then, the electric motor continues to flip downward.

[0047] 5. When the electric motor drives the folding plate 3 to be nearly horizontal, the adhesive plate 4 is located just above the bonding portion and is expanded to a horizontal position after a certain amount of glue is injected through the nozzle 41 on the back. At this time, due to the effect of the crease, the bonding portion of the cardboard has not yet been fully expanded. The electric motor quickly drives the folding plate 3 downward to make the bonding portion fit the side wall of the cardboard until the glue is firmly bonded.

[0048] 6. After maintaining the pressure for a period of time, the electric motor rotates in the opposite direction, driving the folding plate 3 to retract into the installation groove 24. The first servo motor 12 reverses to loosen the cardboard, and then cooperates with the pushing rod inside the box body 1 to push out the bonded cardboard and transport it along the conveyor belt of the other opening 11 of the box body 1 to the packaging area.

[0049] In the above process, in order to prevent the glue from drawing when injecting glue from the nozzle 41, a heater can be set inside the adhesive plate 4 to heat the glue so that the glue remains in a high-temperature liquid state during injection.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
