Generally, the paper boxes used for packaging products are mostly transported to relevant factories in the form of prefabricated cardboard, and then the factories process the prefabricated cardboard (fold the box) to obtain cartons, and then load the relevant products into the boxes.
[0003] In the existing folding machines, problems such as non-standard folding of cartons are likely to occur during the folding process. That is, in the actual operation process, the cardboard is transported to the folding station by a vacuum suction jig.

DETAILED DESCRIPTION
[0021] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.
[0022] The carton packaging folding machine according to an embodiment of the present application will be described below with reference to the accompanying drawings.
[0023] like Figures 1 - 12 As shown, the carton packaging folding machine of the embodiment of the present application includes an equipment frame 1, a cardboard storage device 2, a transportation device 3, a folding device not shown in the figure, two groups of line laser sensors not shown in the figure, multiple groups of cardboard angle fine-tuning devices 10 and a controller not shown in the figure.
[0024] The equipment frame 1 is divided into a loading area 1001 , a cardboard storage area 1002 and a box folding area 1003 , and the box folding area 1003 is arranged between the loading area 1001 and the cardboard storage area 1002 .
[0025] The cardboard storage device 2 is arranged at the cardboard storage area 1002 , wherein the cardboard storage device 2 is used to store cardboards. It should be noted that the cardboards are prefabricated cardboards to be folded into boxes.
[0026] The transport device 3 may include a cardboard transport device 3001, where the cardboard transport device 3001 is arranged in the cardboard storage area 1002, and the cardboard transport device 3001 is located above the cardboard storage device 2.
[0027] The box folding device is arranged in the box folding area 1003.
[0028] Two groups of line laser sensors are respectively arranged above the diagonals of the box folding area 1003.
[0029] The cardboard angle fine-tuning device 10, the number of the cardboard angle fine-tuning devices 10 is multiple groups, preferably four groups. The four groups of cardboard angle fine-tuning devices 10 are respectively arranged on the four side walls of the box folding area 1003.
[0030] The system assembly includes a controller. The controller is respectively connected to the cardboard storage device 2, the transport device 3, the box folding device, the two groups of line laser sensors and the multiple groups of cardboard angle fine-tuning devices 10. The system assembly is used to receive the feedback of each component and make feedback for each step through the edited program.
[0031] The loading area 1001 is used for loading products. The cardboard transport device 3001 moves the cardboard to the box folding area 1003. The box folding area 1003 folds the box according to the product type. The product transport device 3002 places the product in the box, and then moves out the packaged box.
[0032] Specifically, the cardboard transport device 3001 moves the cardboard in the cardboard storage area 1002 above the box folding seat 4. At this time, the two side edges and the two end edges of the cardboard fall on the positions of the cardboard angle fine-tuning devices 10. There is a photoelectric sensor at the position of the box folding seat 4. When the photoelectric sensor at this position senses that there is a cardboard at this position, the two groups of line lasers sense and feed back the corner length of the cardboard to the system assembly. As Figures 11 - 12 shown, if the position of the cardboard is offset, the cardboard angle fine-tuning device 10 adjusts the angle of the cardboard. The cardboard angle offset is calculated by the length of one side of a corner of the cardboard. If the length of one side of a corner of the cardboard is longer than the length of the other side, the position of the cardboard is offset. The specific position needs to be obtained according to the reserved size of the cardboard in the system assembly. The reserved size can be obtained through the opposite moving module three 201 and the opposite moving module four 202 of the cardboard storage device 2, and the size of the cardboard box is obtained through the slider positions of the opposite moving module three 201 and the opposite moving module four 202.
[0033] To further illustrate the present application, in an embodiment of the present application, as Figures 4 - 7As shown, the cardboard angle fine-tuning device 10 includes two groups of cylindrical cylinders 101, two groups of fine-tuning cylinders 102 and an edge adjustment plate 103, wherein the output end of the cylindrical cylinder 101 is rotatably connected to a clamping block 104, a spring 105 is connected between the cylindrical cylinder 101 and the clamping block 104, two groups of clamping grooves adapted to the clamping block 104 are provided at both ends of the surface of the edge adjustment plate 103, the output ends of the two groups of fine-tuning cylinders 102 respectively press against the two ends of the side of the edge adjustment plate 103, and the inner side of the edge adjustment plate 103 is detachably connected to an L-shaped drag plate.
[0034] During the actual operation, when the cardboard is transported to the folding station by the vacuum suction clamp and device, when the vacuum suction clamp is released, the long and thin material of the cardboard and the gap position of the folding device generate airflow, which changes the position of the cardboard. If the position of the cardboard is offset, the folding edge will change during the folding process, which will lead to unsuccessful folding and the inability to put the product in.
[0035] The method of adjusting the angle of the cardboard angle fine-tuning device 10 is to adjust it by obtaining the conditions of the two side angles. During adjustment, a group of cylindrical cylinders 101 descends, a group of clamping blocks 104 disengage from the edge adjustment plate 103, and the two groups of clamping blocks 104 can rotate the adjustable edge adjustment plate 103. At this time, the edge adjustment plate 103 is a tiltable slat. By driving a group of fine-tuning cylinders 102, the fine-tuning cylinders 102 push the end of the edge adjustment plate 103, and the edge adjustment plate 103 tilts and pushes the cardboard to straighten the cardboard. The two groups of cylindrical cylinders 101 are the two rotation axes of the edge adjustment plate 103, and the two angles are adjusted. Through the coordinated action of the four groups of cardboard angle fine-tuning devices 10, the position of the entire cardboard is returned to the correct position, ensuring the folding position and the packing position, and ensuring the yield rate.
[0036] The cardboard angle fine-tuning device 10 adjusts the cardboard in the following steps: Figures 11 - 12 As shown, it is concluded that the sum of the lengths of the two side edges of the lower left corner is greater than the sum of the lengths of the two side edges of the upper right corner. First, the right fine-tuning cylinder 102 of the lower cardboard angle fine-tuning device 10 is pushed to adjust the angle, and the sum of the lengths of the two side edges of the lower left corner is equal to the sum of the lengths of the two side edges of the upper right corner. At this time, fine-tuning is performed by comparing the lengths of the corner sides. If the bottom edge length of the lower left corner is longer than the adjacent edge length, the lower left and upper right are fine-tuned to return the cardboard to the right position. The lengths of the two side edges of the cardboard corner are the same, with an error of not less than ±1.5 cm. The vacuum suction clamp of the folding box seat 4 sucks the cardboard, and the carton begins to fold.
[0037] To further illustrate the present application, in one embodiment of the present application, the laser of the line laser sensor forms an angle of 45 degrees with the side of the folding box seat 4 .
[0038] The line laser sensor is used to measure the lengths of the two sides on both sides of the corner position of the cardboard. The purpose of setting it at a 45-degree angle is that if the line laser directly detects the straight edge, the line laser may shine entirely on the cardboard, and the line laser cannot sense the height difference. To adjust this device, it only needs to adjust the lengths of the two sides of the cardboard to be equal to complete the adjustment.
[0039] To further illustrate the present application, in one embodiment of the present application, as Figures 1 - 3 shown, the folding box device may include: A folding box seat 4, which is located at the middle position of the folding box area 1003, and a vacuum suction fixture is provided on the surface of the folding box seat 4.
[0040] Two first side-up folding cylinders 5, which are arranged in two groups. The two groups of first side-up folding cylinders 5 are respectively arranged on both sides of the folding box seat 4, and the first side-up folding cylinders 5 are used to fold up the two sides of the cardboard.
[0041] Two first horizontal side cylinders 6, which are arranged in two groups. The two groups of first horizontal side cylinders 6 are respectively fixed at the output ends of the two groups of first side-up folding cylinders 5, and the first horizontal side cylinders 6 are used to horizontally push the two sides of the cardboard after being folded up.
[0042] Two second side-up folding cylinders 7, which are arranged in two groups. The two groups of second side-up folding cylinders 7 are respectively arranged on both sides of the folding box seat 4, and the second side-up folding cylinders 7 are used to fold up the two end sides of the cardboard.
[0043] Two second horizontal side cylinders 8, which are arranged in two groups. The two groups of second horizontal side cylinders 8 are respectively fixed at the output ends of the two groups of second side-up folding cylinders 7, and the second horizontal side cylinders 8 are used to horizontally push the two end sides of the cardboard after being folded up.
[0044] Four wrapping edge cylinders 9, which are arranged in four groups. Two groups of wrapping edge cylinders 9 are respectively arranged on both sides of the folding box seat 4, and the wrapping edge cylinders 9 are used to fold up the wrapping edge 15 of the cardboard.
[0045] When the cardboard box lands on the folding box seat 4, if it is detected that the cardboard has met the error of the folding position, at this time, the folding box device is controlled to fold the cardboard box. The wrapping edge cylinder 9 rises, lifting the wrapping edge 15 of the cardboard box. The second side up-folding cylinder 7 folds up the end edge of the cardboard box, and then the first side up-folding cylinder 5 folds up the side edge of the cardboard box. The second horizontal side cylinder 8 pushes to fold the side edge horizontally. The descending cylinder 3013 of the product transportation device 3002 descends, pressing down the horizontally folded side edge. At the same time, the horizontally folded side edge wraps the wrapping edge 15. Both the horizontally folded side edge and the wrapping edge 15 are wavy edges. The horizontally folded side edge wraps the wrapping edge 15, that is, the wavy edges are fitted to complete the fitting of the waveform indentation and the waveform protrusion positions. The pressing head 3014 presses the horizontally folded side edge to the bottom plate of the cardboard box. A notch is formed at the end of the horizontally folded side edge and the bottom plate of the cardboard box, that is, the wrapping of the cardboard box is completed, and the cardboard box folding action is completed. There can be a notch at both sides of the bottom plate of the cardboard box, that is, the pressing position at the end of the horizontally folded side edge. The end of the horizontally folded side edge can be an expansion head or be provided with an expansion head. The expansion head can be a metal head to facilitate the pressing of the pressing head 3014.
[0046] After the folding of the box is completed, the product transportation device 3002 moves to the product area. After placing the product inside the box, then the two groups of first side up-folding cylinders 5 move successively to wrap the product inside the box, and the product transportation device 3002 moves out the packaged product.
[0047] In an embodiment of the present application, as Figure 1 and Figure 8 shown, the transportation device further includes a product transportation device 3002. The product transportation device 3002 includes a linear module 3011 and a gripper opposing movement linear module 3012. The linear module 3011 is arranged at the feeding area 1001 position. The moving end of the linear module 3011 is provided with a gripper opposing movement linear module 3012. Two sets of descending cylinders 3013 are respectively fixed on the two-way moving ends of the gripper opposing movement linear module 3012. The output end of the descending cylinder 3013 is connected with a pressing head 3014.
[0048] The pressing head 3014 of the product transportation device 3002 is used for gripping the packaged product and for pressing down the cardboard on the two sides after horizontal pushing and pressing the end of the cardboard to the bottom of the cardboard box.
[0049] When the folding box is completed, the product transportation device 3002 loads the product. The product transportation device 3002 loads the product into the folded cardboard box. The clamping jaw opposing movement linear module 3012 moves to the folding box area 1003 or the loading area 1001 through the linear module 3011, so that the pressing head 3014 presses the cardboard box, loads the product into the box, and removes the product after the loading into the box is completed. The clamping jaw opposing movement linear module 3012 is used to adjust the relative positions of the two sets of descending cylinders 3013, so as to adapt to the size of the product and the required size of the cardboard box to be folded. After the cardboard for folding the box is completed, the pressing head 3014 clamps the product and moves it above the box body. The descending cylinder 3013 descends, places the product inside the box body, then the descending cylinder 3013 rises and the pressing plate moves out. The clamping jaw opposing movement linear module 3012 expands the distance between the two sets of pressing heads 3014, then descends, clamps the packaged product, and then moves it out through the linear module 3011.
[0050] The opposing movement module one 111 and the opposing movement module two 112 can adjust the distance between the folding box devices, so as to adjust and fold cardboard boxes of different sizes.
[0051] In an embodiment of the present application, as Figure 1 and Figure 9 shown, the cardboard storage device 2 includes an opposing movement module three 201 and an opposing movement module four 202. The opposing movement module three 201 and the opposing movement module four 202 are arranged horizontally and vertically.

Two sets of slide rails two 204 are slidably connected on the track of the slide rail one 203. Two sets of cardboard clamps 205 are slidably connected on the track of the slide rail two 204. Two-way moving ends of the opposing movement module four 202 are respectively connected with the two sets of cardboard clamps 205.
[0052] The cardboard storage device 2 is used to store cardboard boxes. Multiple cardboard storage devices 2 can be set to place cardboard of different sizes. Different cardboard are selected according to different products. A cardboard transportation device 3001 is placed above each cardboard storage device 2, so that the discharge port of the cardboard transportation device 3001 is arranged above the folding box area 1003. The position of the cardboard clamp 205 of the cardboard storage device 2 can be adjusted. By driving the opposing movement module three 201 and the opposing movement module four 202, the opposing movement module three 201 is used to move the distance between the two sets of slide rails one 203, so as to move the lateral positions of the two sets of cardboard clamps 205 and the other two sets of cardboard clamps 205. The opposing movement module four 202 is used to move the slider positions on the slide rail two 204, so as to move the longitudinal positions of the two sets of cardboard clamps 205 and the other two sets of cardboard clamps 205. The position of the cardboard clamp 205 is adjusted by adjusting the slider position, so that the cardboard adapts to the space of the four sets of cardboard clamps 205. The adjustment position distance is obtained according to the size of the cardboard through the adjustment device, that is, the pushing distance of the fine adjustment cylinder 102.

[0059] In an embodiment of the present application, as Figure 1 shown, it further includes a feeding conveyor belt 13 and a discharging conveyor belt 14. The feeding conveyor belt 13 and the discharging conveyor belt 14 are both arranged in the feeding area 1001. The feeding area 1001 is provided with a CCD industrial camera and a photoelectric sensor. Side conveyor belts are arranged on both sides of the feeding conveyor belt 13. The side conveyor belts are connected through an opposing adjusting device, and the opposing adjusting device is used to adjust the distance between the side conveyor belts. The side conveyor belts clamp and convey the product to determine the position of the product, that is, to determine the left and right positions of the product.
[0060] The product can move through the feeding conveyor belt 13 to the feeding port of the product transportation device 3002. The packaged product moves through the product transportation device 3002 to the discharging conveyor belt 14 again. When the product moves to the position of the feeding conveyor belt 13, the photoelectric switch senses that the product moves to the clamping position, that is, the front and back positions of the product are determined, ensuring the clamping position. By setting the CCD industrial camera to capture the side features of the product, the position of the product can be further accurately determined.
[0061] It should be noted that the linear module 3011 described in the specification includes a ball screw, a screw bearing seat, a screw motor, and a guide rail. The opposing linear module 3011 includes a bidirectional ball screw, a screw bearing seat, a screw motor, and a guide rail. The linear module 3011 performs a linear motion, and the opposing linear module 3011 performs an opposing motion.
[0062] Specifically, in the actual execution process: 1. The cardboard transportation device 3001 moves the cardboard in the cardboard storage area 1002 above the folding box seat 4. At this time, the two side edges and the two end edges of the cardboard fall on the cardboard angle fine-tuning device 10. The folding box seat 4 is provided with a photoelectric sensor. When the photoelectric sensor at this position senses that there is cardboard at this position, two sets of line lasers sense and feedback the corner length of the cardboard to the system assembly, as Figures 11 - 12 shown. If the position of the cardboard is offset, the cardboard angle fine-tuning device 10 adjusts the angle of the cardboard. The cardboard angle offset is calculated based on the length of the edges at the corners of the cardboard. If the length of one side of a corner of the cardboard is longer than the length of the other side, the position of the cardboard is offset. The specific position needs to be obtained according to the reserved size of the cardboard in the system assembly.
[0063] 2. The method for adjusting the angle of the cardboard angle fine-tuning device 10 is to adjust it by obtaining the conditions of the two side angles. During adjustment, a group of cylindrical cylinders 101 descend. At this time, the edge-adjusting plate 103 is a tiltable slat. By driving a group of fine-tuning cylinders 102, the fine-tuning cylinders 102 push the end of the edge-adjusting plate 103, and the edge-adjusting plate 103 tilts to push the cardboard, so that the cardboard is straightened. The two groups of cylindrical cylinders 101 are the two rotation axes of the edge-adjusting plate 103. Through the coordinated action of the four groups of cardboard angle fine-tuning devices 10, the position of the overall cardboard is corrected, ensuring the folding box position and the packing position, and ensuring the good product rate.
[0064] 3. The steps for adjusting the cardboard by the cardboard angle fine-tuning device 10 are as follows. As Figures 11 - 12 shown, it is obtained that the sum of the lengths of the two side edges of the lower left corner is greater than the sum of the lengths of the two side edges of the upper right corner. First, the right fine-tuning cylinder 102 of the lower cardboard angle fine-tuning device 10 for adjusting the angle is pushed. When the sum of the lengths of the two side edges of the lower left corner is equal to the sum of the lengths of the two side edges of the upper right corner, at this time, fine-tuning is performed by comparing the lengths of the side edges of the corners. If the length of the bottom edge of the lower left corner is longer than the length of the adjacent edge, fine-tuning is performed from the lower left to the upper right to straighten the cardboard. The lengths of the two side edges of the corner of the cardboard are the same, and the error is not less than ±1.5 cm. The vacuum suction clamp of the folding box seat 4 sucks the cardboard, and the carton starts to be folded.
[0065] 4. The wrapping edge cylinder 9 rises, lifting the wrapping edge 15 of the carton. The second side folding cylinder 7 folds up the end edge of the carton, and then the first side folding cylinder 5 folds up the side edge of the carton. The second horizontal side cylinder 8 pushes to fold the side edge horizontally. The product transportation device 3002's lowering cylinder 3013 descends, pressing down the horizontally folded side edge. At the same time, the horizontally folded side edge wraps the wrapping edge 15, and the pressing head 3014 presses the horizontally folded side edge to the bottom plate of the carton. A recessed opening is formed at the end of the horizontally folded side edge and the bottom plate of the carton, that is, the carton wrapping is completed, and the cardboard completes the carton folding action.
[0066] 5. The clamping jaw moving linearly in opposite directions module 3012 moves to the folding box area 1003 or the feeding area 1001 through the linear module 3011, so that the pressing head 3014 performs the pressing of the carton, the feeding of the product into the box, and the removal of the product after the box is filled. The clamping jaw moving linearly in opposite directions module 3012 is used for the relative position of the two groups of lowering cylinders 3013, so as to adapt to the size of the product and the size of the carton to be folded. After the cardboard for folding the box is completed, the pressing head 3014 clamps the product and moves it above the box body. The lowering cylinder 3013 descends, placing the product inside the box body. Then the lowering cylinder 3013 rises and the pressing plate moves out. The clamping jaw moving linearly in opposite directions module 3012 expands the distance between the two pressing heads 3014, and then descends, clamping the packaged product, and then moving it out through the linear module 3011.
[0067] In summary, the carton packaging folding machine according to the embodiments of the present application can integrally form and package products and cartons, thereby accelerating the production efficiency. The device can also fold cartons of different sizes according to different products, and position the cartons through an adjustment device, ensuring the accuracy of the folding edge position of the cartons and facilitating box loading after the cartons are positioned.
