Description

Technical Field

[0001] This disclosure relates to the field of printing equipment technology, and in particular to a vertical packaging box printing flipping device and a printing machine. Background Technology

[0002] A printing press is a software-controlled device that marks products (marking refers to various types of barcodes, text, graphics, etc.). It typically uses two methods: contact printing and non-contact printing. Non-contact methods include Continuous Inkjet Printer (CIJ), Piezoelectric Inkjet Printer (PIJ), and Thermal Inkjet Printer (TIJ).

[0003] In the current cardboard packaging industry, the traditional method for printing product information such as production order number, place of production, and weight on the outer surface of cardboard boxes is to print while the box is still flat and not folded. This requires manual flipping at least once to print on multiple sides. After printing, the box needs to be folded again before being put into the packaging process. Similarly, for folded upright cardboard boxes, only the top can be printed, requiring manual flipping at least once to print on the other sides. Moreover, the boxes are prone to falling during the flipping process, resulting in low printing efficiency. Utility Model Content

[0026] This disclosure relates to a vertical packaging box printing and flipping device. In one embodiment, the vertical packaging box printing and flipping device includes a printing base, a packaging box flipping mechanism, and a printing mechanism. The printing base is used to mount an infeed conveyor belt and an unfeed conveyor belt for transporting the vertical packaging box. The vertical packaging box flipping mechanism includes a transfer conveyor belt and a box-clamping and flipping assembly. The transfer conveyor belt is located between the infeed conveyor belt and the unfeed conveyor belt, and is used to transfer the vertical packaging box. The box-clamping and flipping assembly is mounted on the printing base and is correspondingly mounted to the transfer conveyor belt. The clamping and flipping end of the box-clamping and flipping assembly is used to connect to both the vertical packaging box and the transfer conveyor belt, so that the vertical packaging box and the transfer conveyor belt flip together. The printing mechanism is mounted on the printing base and is used to perform coded printing ink operations on at least two surfaces of the vertical packaging box. After the upright packaging box is placed on the transfer conveyor belt, the box-clamping and flipping component corresponds to the transfer conveyor belt, which allows the box-clamping and flipping component to clamp and fix the transfer conveyor belt and the upright packaging box together, making it more stable during flipping. When the printing mechanism performs multi-sided printing on the upright packaging box, the box-clamping and flipping component flips the transfer conveyor belt and the upright packaging box synchronously, so that the surface of the upright packaging box is flat and does not warp or deform. This allows the printing mechanism to form the code containing various information on multiple surfaces of the upright packaging box through printing ink, without the need for manual flipping, effectively improving the efficiency of multi-sided printing on the upright packaging box.

[0027] Please see Figure 1 This is a schematic diagram of the structure of a vertical packaging box printing and flipping device according to an embodiment of the present disclosure.

[0028] One embodiment of the vertical packaging box printing and flipping device 10 includes a printing base 100, a packaging box flipping mechanism 200, and a printing mechanism 300. The printing base 100 is used to mount the loading conveyor belt and unloading conveyor belt for transporting the vertical packaging boxes. Please refer to the accompanying documentation. Figure 2 The vertical packaging box flipping mechanism 200 includes a transfer conveyor belt 210 and a box-hugging and flipping assembly 220. The transfer conveyor belt 210 is located between the loading conveyor belt and the unloading conveyor belt and is used to transfer the vertical packaging box. The box-hugging and flipping assembly 220 is disposed on the printing base 100 and is correspondingly disposed with the transfer conveyor belt 210. The clamping and flipping end of the box-hugging and flipping assembly 220 is used to connect to both the vertical packaging box and the transfer conveyor belt 210, so that the vertical packaging box and the transfer conveyor belt 210 flip together. The printing mechanism 300 is disposed on the printing base 100 and is used to perform coded printing ink operations on at least two surfaces of the vertical packaging box.

[0029] In this embodiment, after the upright packaging box is placed on the transfer conveyor belt 210, the box-hugging and flipping component 220 corresponds to the transfer conveyor belt 210, which facilitates the box-hugging and flipping component 220 to hold and fix the transfer conveyor belt 210 and the upright packaging box together, making it more stable during flipping and preventing the upright packaging box from falling off the transfer conveyor belt 210. When the printing mechanism 300 performs multi-sided printing on the upright packaging box, the box-hugging and flipping component 220 flips the transfer conveyor belt 210 and the upright packaging box synchronously, making the surface of the upright packaging box flat and free from warping and deformation. This allows the printing mechanism 300 to form codes with various information on multiple surfaces of the upright packaging box through printing ink, without the need for manual flipping, effectively improving the efficiency of multi-sided printing on the upright packaging box.

[0030] In one embodiment, the printing mechanism can perform printing in a contact or non-contact manner; for example, the printing mechanism is a screen printing mechanism; or, for example, the printing mechanism is an inkjet printing mechanism.

[0031] In one embodiment, please refer to Figure 2 The box-hugging and flipping assembly 220 includes two opposing flipping clamping members 222. Each flipping clamping member 222 includes a flipping drive rod 2222 and a box clamping plate 2224. The box clamping plate 2224 is located on the side of the transfer conveyor belt 210 and abuts against the vertical packaging box and the transfer conveyor belt 210. One end of the flipping drive rod 2222 is connected to the rotating shaft of the flipping drive mechanism, and the other end is connected to the box clamping plate 2224. In this embodiment, the two flipping clamping members 222 are located on both sides of the transfer conveyor belt 210. For example, the box clamping plate 2224 and the transfer conveyor belt 210 are arranged parallel to each other in the transmission direction. The flipping clamping member 222 fixes the vertical packaging box and the transfer conveyor belt 210 by clamping them together. Specifically, the box clamping plate 2224 abuts against the side of the vertical packaging box and the side of the transfer conveyor belt 210 respectively, so that the two box clamping plates 2224 jointly clamp the vertical packaging box and the transfer conveyor belt 210, thereby keeping the vertical packaging box and the transfer conveyor belt 210 in a fixed relative position. The flipping drive rod 2222, as an extension of the rotating shaft of the flipping drive mechanism, is fixedly connected to the rotating shaft of the flipping drive mechanism. When the rotating shaft of the flipping drive mechanism rotates, the flipping drive rod 2222 drives the box clamping plate 2224 to rotate, so that the vertical packaging box and the transfer conveyor belt 210 flip synchronously, which facilitates multi-sided printing by the printing mechanism 300 and improves the printing efficiency of the vertical packaging box.

[0032] Further, please refer to Figure 2 The vertical packaging box flipping mechanism 200 further includes a clamping positioning sensor 230, which is disposed on the box clamping plate 2224. The sensing end of the clamping positioning sensor 230 faces the vertical packaging box to sense the clamping distance between the box clamping plate 2224 and the vertical packaging box. In this embodiment, the clamping positioning sensor 230 is located on the box clamping plate 2224. The clamping positioning sensor 230 serves as a sensing device for the distance between the box clamping plate 2224 and the vertical packaging box. The clamping positioning sensor 230 determines the distance between the box clamping plate 2224 and the vertical packaging box, ensuring the contact between the box clamping plate 2224 and the vertical packaging box, and avoiding excessive compression of the vertical packaging box by the box clamping plate 2224 during flipping.

[0033] In another embodiment, the flipping drive rod 2222 has a telescopic function to adjust the squeezing force between the box clamping plate 2224 and the vertical packaging box according to the distance sensed by the clamping positioning sensor 230. For example, the flipping drive rod 2222 is an adjustable-length telescopic rod; or the flipping drive mechanism is connected to the telescopic end of a telescopic mechanism, and the telescopic function of the telescopic end of the telescopic mechanism is used to adjust the extension and retraction of the flipping drive rod 2222.

[0034] In one embodiment, please refer to Figure 3 The box clamping and flipping assembly 220 further includes a first clamping member 224, which includes a first clamping cylinder 2242 and a first clamping clamping plate 2244. The first clamping cylinder 2242 is connected to the box clamping plate 2224, and the telescopic end of the first clamping cylinder 2242 is connected to the first clamping clamping plate 2244. The first clamping clamping plate 2244 and the box clamping plate 2224 are arranged parallel to each other, and the first clamping clamping plate 2244 is used to abut against the first surface of the vertical packaging box. In this embodiment, the first clamping cylinder 2242 is located on the box clamping plate 2224. The first clamping cylinder 2242 serves as the extension and retraction power source for the first clamping plate 2244. Under the extension and retraction of the extension end of the first clamping cylinder 2242, the first clamping plate 2244 is stably held against the first surface of the vertical packaging box, thereby increasing the clamping contact area of ​​the vertical packaging box and increasing the clamping force of the vertical packaging box. As a result, the first clamping plate 2244 and the box clamping plate 2224 jointly clamp the vertical packaging box, thereby improving the clamping stability of the vertical packaging box.

[0035] Further, please refer to Figure 3 The box clamping plate 2224 has a through hole 202. The telescopic end of the first clamping cylinder 2242 passes through the through hole 202, so that the first clamping clamping plate 2244 moves closer to or further away from the vertical packaging box. In this embodiment, the through hole 202 is provided on the box clamping plate 2224, and the through hole 202 corresponds to the first clamping cylinder 2242. The telescopic end of the first clamping cylinder 2242 moves within the through hole 202, so that the first clamping clamping plate 2244 abuts against the first surface of the vertical packaging box after passing through the through hole 202, thereby facilitating stable clamping of the first surface of the vertical packaging box.

[0036] In another embodiment, there are two first clamping members 224, and the two first clamping clamps 2244 are respectively located on both sides of the vertical packaging box. The first clamping clamps 2244 correspond one-to-one with the box body clamping plate 2224, and the through hole 202 is located in the middle of the first clamping clamp 2244.

[0037] In one embodiment, please refer to Figure 2 The box-hugging and flipping assembly 220 further includes a second clamping member 226, which includes a second clamping cylinder 2262 and a second clamping clamping plate 2264. The second clamping cylinder 2262 is connected to the box-hugging plate 2224, and the telescopic end of the second clamping cylinder 2262 is connected to the second clamping clamping plate 2264. The second clamping clamping plate 2264 and the box-hugging plate 2224 are arranged perpendicularly to each other, and the second clamping clamping plate 2264 is used to abut against the second surface of the vertical packaging box. In this embodiment, the second clamping cylinder 2262 is located on the box-hugging plate 2224. The second clamping cylinder 2262 serves as the power source for the telescopic movement of the second clamping clamping plate 2264. Under the telescopic movement of the telescopic end of the second clamping cylinder 2262, the second clamping clamping plate 2264 is stably held against the second surface of the vertical packaging box, thereby increasing the fixed contact area of ​​the vertical packaging box. Furthermore, the second clamping plate 2264 is perpendicular to the box clamping plate 2224, that is, the second clamping plate 2264 is parallel to the second surface of the vertical packaging box, so that the second clamping plate 2264 and the first clamping plate 2244 fix the vertical packaging box from two mutually perpendicular directions, thereby further improving the clamping stability of the vertical packaging box.

[0038] Further, please refer to Figure 2The second clamping plate 2264 includes a clamping base plate 2264a and a turning connecting portion 2264b connected to each other. The clamping base plate 2264a abuts against the second surface of the vertical packaging box, and the turning connecting portion 2264b corresponds to the first surface of the vertical packaging box. The turning connecting portion 2264b is detachably connected to the telescopic end of the second clamping cylinder 2262. In this embodiment, the clamping base plate 2264a is parallel to the second surface of the vertical packaging box and perpendicular to the first clamping plate 2244. The clamping base plate 2264a fixes the second surface of the vertical packaging box. The turning connection 2264b is located between the clamping base plate 2264a and the second clamping cylinder 2262. The turning connection 2264b is also opposite to the first surface, so that the clamping base plate 2264a is connected to the telescopic end of the second clamping cylinder 2262 through the turning connection 2264b, thereby allowing the clamping base plate 2264a to rise and fall on the second surface perpendicular to the vertical packaging box, which facilitates clamping and squeezing the second surface of the vertical packaging box.

[0039] In one embodiment, please refer to Figure 2 The box-hugging and flipping assembly 220 further includes a third clamping member 228, which includes a third clamping cylinder 2282 and a clamping hinge gripper 2284. The third clamping cylinder 2282 is connected to the box-hugging plate 2224, and the telescopic end of the third clamping cylinder 2282 is connected to the clamping hinge gripper 2284. The clamping hinge gripper 2284 is used to abut against the third surface of the vertical packaging box, and the third surface of the vertical packaging box is perpendicular to both the first and second surfaces of the vertical packaging box. In this embodiment, the third clamping cylinder 2282 is located on the box clamping plate 2224. The third clamping cylinder 2282 serves as the power source for the extension and retraction of the clamping hinge claw 2284. Under the extension and retraction of the extension end of the third clamping cylinder 2282, the clamping hinge claw 2284 is stably held against the third surface of the vertical packaging box, increasing the fixed contact area of ​​the vertical packaging box. Furthermore, the contact surface between the clamping hinge claw 2284 and the vertical packaging box is the third surface, which is perpendicular to both the first and second surfaces. This generates a common clamping force in the three perpendicular directions of the vertical packaging box, further improving its stability during flipping. Thus, by using clamping mechanisms in each direction to hold each surface of the vertical packaging box flat, the distance between the inkjet nozzle and the printing surface of the vertical packaging box is uniform during printing, avoiding uneven printing caused by surface warping in vertical packaging boxes without clamping mechanisms.

[0040] In another embodiment, the clamping hinge gripper 2284 is a hinge structure, wherein one leaf abuts against the first surface, and the other leaf abuts against the third surface and is connected to the telescopic end of the third clamping cylinder.

[0041] In another embodiment, the vertical packaging box is a cube or cuboid. There are two of each of the first clamping member 224, the second clamping member 226, and the third clamping member 228. The two first clamping members 224 are positioned opposite each other, the two second clamping members 226 are positioned opposite each other, and the two third clamping members 228 are positioned opposite each other. Specifically, the two first clamping members 224 correspond to two opposite sides of the vertical packaging box, the two second clamping members 226 correspond to the bottom and top surfaces of the vertical packaging box, and the two third clamping members 228 correspond to the front and rear surfaces of the vertical packaging box. The front surface of the vertical packaging box faces the unloading conveyor belt, and the rear surface faces the loading conveyor belt.

[0042] In another embodiment, the number of the second clamping member 226 is one, and the second clamping member 226 abuts against the top surface of the upright packaging box to hold the upright packaging box against the transfer conveyor belt 210. When flipped, the transfer conveyor belt 210 stops transporting.

[0043] In another embodiment, there is one third clamping member 228. The third clamping member 228 abuts against the rear end face of the vertical packaging box. The transfer conveyor belt 210 is provided with a liftable baffle. The baffle is arranged opposite to the third clamping member 228. The baffle is used to rise before the vertical packaging box is flipped so as to abut against the front end face of the vertical packaging box, so that the vertical packaging box is positioned on the transfer conveyor belt 210 and clamped together with the third clamping member 228.

[0044] In one embodiment, please refer to Figure 2The vertical packaging box printing flipping device 10 further includes a flipping drive mechanism 400. The flipping drive mechanism 400 includes a rotating shaft seat 410, a first rotating connecting rod 420, a second rotating connecting rod 430, and a flipping drive cylinder 440. The rotating shaft seat 410 has a rotating hole 402. The flipping drive rod 2222 passes through the rotating hole 402. One end of the flipping drive rod 2222 away from the box clamping plate 2224 is connected to the first rotating connecting rod 420. The first rotating connecting rod 420 is rotatably connected to the second rotating connecting rod 430. The second rotating connecting rod 430 is also connected to the telescopic end of the flipping drive cylinder 440. The flipping drive cylinder 440 is disposed on the printing base 100. In this embodiment, the first rotating connecting rod 420 and the second rotating connecting rod 430 are rotatably connected to each other to form a connecting rod structure. The first rotating connecting rod 420 rotates around the end of the flipping drive rod 2222, and the second rotating connecting rod 430 rotates around the end of the first rotating connecting rod 420. The flipping drive rod 2222 is rotatably inserted into the rotating hole 402. Under the extension and retraction of the telescopic end of the flipping drive cylinder 440, it drives the second rotating connecting rod 430 to move, so that the first rotating connecting rod 420 rotates simultaneously at two connection points on itself, that is, at the connection points of the first rotating connecting rod 420, the second rotating connecting rod 430, and the flipping drive rod 2222. In this way, when the telescopic end of the flipping drive cylinder 440 extends and retracts, the flipping drive rod 2222 rotates, which facilitates the flipping of the vertical packaging box.

[0045] Further, please refer to Figure 2 The flipping drive mechanism 400 further includes a flipping limiting member 450, which includes a flipping limiting frame 452 and a flipping limiting rod 454 connected to each other. The flipping limiting frame 452 is disposed on the printing base 100, and the flipping limiting rod 454 is disposed adjacent to the flipping drive rod 2222, and the flipping limiting rod 454 is located on the rotating fan surface corresponding to the rotation trajectory of the flipping drive rod 2222. In this embodiment, the flipping limiting frame 452 serves as the mounting bracket for the flipping limiting rod 454. The end of the flipping limiting rod 454 faces the side of the flipping driving rod 2222. The flipping driving rod 2222 forms a rotating fan during rotation. The flipping limiting rod 454 is used to abut against the flipping driving rod 2222 when it rotates to a designated position, so that the rotation angle of the flipping driving rod 2222 is limited within a specified range. This fixes the flipping angle of the vertical packaging box, making it easier to flip the surface of the vertical packaging box that needs to be flipped for printing so that it faces the printing mechanism 300, thereby improving the printing alignment accuracy.

[0046] In another embodiment, there are two flipping limiting members 450, which are arranged opposite to each other. The rotation angle formed by the flipping drive rod 2222 and the two flipping limiting rods 454 at their respective abutment positions is 90°, so that the rotation angle of the flipping drive rod 2222 is 90°, which facilitates the printing operation on two adjacent vertical surfaces of the cubic vertical packaging box.

[0047] In one embodiment, please refer to Figure 1 The printing mechanism 300 includes a three-axis moving assembly 310, a printing ink tank 320, and a UV lamp 330. The three-axis moving assembly 310 is mounted on the printing base 100. The printing ink tank 320 is connected to the moving end of the three-axis moving assembly 310, with the printing end of the printing ink tank 320 facing the printing base 100. The UV lamp 330 is mounted on the printing ink tank 320, and the UV lamp 330 and the printing ink tank 320 are arranged sequentially along the transport direction of the transfer conveyor belt 210. The curing light output end of the UV lamp 330 faces the printing base 100. In this embodiment, the three-axis moving assembly 310 serves as a spatial moving component for the printing ink tank 320 and the UV lamp 330. Specifically, the three-axis moving assembly 310 has movement functions in three mutually perpendicular directions: X, Y, and Z. Driven by the three-axis moving assembly 310, the printing ink tank 320 and the UV lamp 330 can be moved to positions corresponding to the transfer conveyor belt 210, for example, both the printing ink tank 320 and the UV lamp 330 are located above the transfer conveyor belt 210. Thus, during the printing operation, the printing ink tank 320 and the UV lamp 330 move along the transport direction of the transfer conveyor belt 210. The printing ink tank 320 sprays ink onto the printing area of ​​the vertical packaging box, and then the UV lamp 330 uses ultraviolet light to cure the ink in the printing area, facilitating the rapid formation of a durable and non-removable code.

[0048] In another embodiment, the UV lamp 330 is also connected to the main controller in the printing ink tank 320. After the printing ink tank 320 prints ink on any printing area, the main controller controls the UV lamp 330 to turn on and controls the turning time to improve the curing effect of the ink.

[0049] In another embodiment, the printing ink tank 320 has multiple nozzles. Specifically, the printing ink tank 320 uses three nozzles to complete printing at one time, that is, the three nozzles spray ink in stages during one movement.

[0050] In one embodiment, please refer to Figure 1The vertical packaging box printing and flipping device 10 also includes an electrostatic dust removal mechanism 500, which includes a feeding conveyor belt 510 and an electrostatic dust removal assembly 520. The feeding conveyor belt 510 is disposed on the printing base 100. Please refer to the attached document for further details. Figure 4 The electrostatic dust removal assembly 520 includes an electrostatic dust removal bracket 522, a first electrostatic dust removal ionizing air bar 524, and a box-type code reader 526. The electrostatic dust removal bracket 522 is disposed on the printing base 100, and the first electrostatic dust removal ionizing air bar 524 is disposed on the electrostatic dust removal bracket 522. The air outlet end of the first electrostatic dust removal ionizing air bar 524 faces the feeding conveyor belt 510. The first electrostatic dust removal ionizing air bar 524 is used to output ionizing air to the vertical packaging box to remove surface dust from the vertical packaging box. The box-type code reader 526 is connected to the electrostatic dust removal bracket 522, and the reading end of the box-type code reader 526 faces the feeding conveyor belt 510. The box-type code reader 526 is used to read the code of the vertical packaging box to activate the first electrostatic dust removal ionizing air bar 524. In this embodiment, both the first electrostatic dust removal ionizing air bar 524 and the box reader 526 are mounted on the electrostatic dust removal bracket 522. The box reader 526 collects the code of the upright packaging box to determine its type, thereby facilitating the determination of whether electrostatic dust removal is required. When dust removal is needed, the first electrostatic dust removal ionizing air bar 524 blows ionizing air onto the surface of the upright packaging box based on the information read by the box reader 526, removing dust from the surface of the upright packaging box through electrostatic dust removal, facilitating subsequent printing of ink on the clean surface to form stable new coding information.

[0051] Further, please refer to Figure 4The electrostatic dust removal assembly 520 further includes a first lifting rod 528, a second lifting rod 521, and a second electrostatic dust removal ionizer 523. Both the first lifting rod 528 and the second lifting rod 521 are connected to the electrostatic dust removal bracket 522. The lifting end of the first lifting rod 528 is connected to the box reader 526, allowing the box reader 526 to move closer to or further away from the feeding conveyor belt 510. The lifting end of the second lifting rod 521 is connected to the second electrostatic dust removal ionizer 523, allowing the second electrostatic dust removal ionizer 523 to move closer to or further away from the feeding conveyor belt 510. In this embodiment, the first lifting rod 528 serves as a movable component of the box reader 526, facilitating the extension and retraction of the box reader 526 above the feeding conveyor belt 510. This allows the box reader 526 to read codes from the top and front and rear ends of the vertical packaging box, improving the accuracy of information collection from the vertical packaging box. The second lifting rod 521 serves as a movable component of the second electrostatic dust removal ion bar 523. Under the extension and retraction of the second lifting rod 521, the second electrostatic dust removal ion bar 523 extends and retracts above the feeding conveyor belt 510, facilitating electrostatic dust removal of the top and front and rear ends of the vertical packaging box, thereby improving the dust removal effect of the vertical packaging box.

[0052] In another embodiment, both the first lifting rod and the second lifting rod are sleeve structures, namely, an outer tube and a lifting inner tube that are sleeved together. The outer tube is sleeved on the lifting inner tube and is connected to the electrostatic dust removal bracket. The lifting inner tube slides through the outer tube, with one end of the lifting inner tube serving as the lifting end and the other end of the lifting inner tube connected to the lifting cylinder or motor.

[0053] In one embodiment, please refer to Figure 1The vertical packaging box printing and flipping device 10 further includes a printing inspection mechanism 600. The printing inspection mechanism 600 includes a feeding conveyor belt 610, an output conveyor belt 620, and a code reading and verification component 630. The feeding conveyor belt 610 and the output conveyor belt 620 are both disposed on the printing base 100, with the output conveyor belt 620 disposed adjacent to the feeding conveyor belt 610. The code reading and verification component 630 includes a code reading and verification guide rail 632 and a code reading and verification device 634. The code reading and verification guide rail 632 is disposed on the printing base 100, and the code reading and verification device 634 is slidably connected to the code reading and verification guide rail 632. The collecting end of the code reading and verification device 634 faces the feeding conveyor belt 610. The code reading and verification device 634 is used to verify the printing on the vertical packaging box so that the output conveyor belt 620 can be driven to remove the vertical packaging box with printing errors. In this embodiment, the unloading conveyor belt 610 and the code reader 634 are arranged opposite each other. The code reader 634 collects and verifies the printing on the upright packaging box to determine whether there are any errors in the printing. Specifically, it detects the clarity of the printing and the correctness of the coding information. The output conveyor belt 620 works in conjunction with the unloading conveyor belt 610. When the printing on the upright packaging box is error-free, the code reader 634 sends a continue transmission signal to the unloading conveyor belt 610 and a stop transmission signal to the output conveyor belt 620, allowing the error-free upright packaging box to enter the next normal process. Conversely, when there is an error in the printing on the upright packaging box, the code reader 634 sends a stop transmission signal to the unloading conveyor belt 610 and an start transmission signal to the output conveyor belt 620, causing the error-printed upright packaging box to enter the NG (not good) process, thus preventing the error-printed upright packaging box from entering the next normal process.

[0054] In another embodiment, the unloading conveyor belt includes multiple sequentially arranged sub-conveyors, with a portion of the discharge conveyor belt located between any two adjacent sub-conveyors, such that the unloading conveyor belt and the discharge conveyor belt are interlocked. This ensures that the conveying surfaces are flush, facilitating the transport of vertical packaging boxes on different conveyor belts. This facilitates the screening of vertical packaging boxes, ensuring that qualified printed vertical packaging boxes are accurately delivered to the next production process, while unqualified printed vertical packaging boxes are rejected.

[0055] In one embodiment, this disclosure also relates to a printing machine including the vertical packaging box printing and turning device described in any of the above embodiments. In this embodiment, the vertical packaging box printing and turning device includes a printing base, a packaging box turning mechanism, and a printing mechanism. The printing base is used to house an infeed conveyor belt and an unfeed conveyor belt for transporting the vertical packaging box. The vertical packaging box turning mechanism includes a transfer conveyor belt and a box-clamping and turning assembly. The transfer conveyor belt is located between the infeed conveyor belt and the unfeed conveyor belt, and is used to transfer the vertical packaging box. The box-clamping and turning assembly is disposed on the printing base and is correspondingly disposed with the transfer conveyor belt. The clamping and turning end of the box-clamping and turning assembly is used to connect to both the vertical packaging box and the transfer conveyor belt, so that the vertical packaging box and the transfer conveyor belt turn together. The printing mechanism is disposed on the printing base and is used to perform coded printing ink operations on at least two surfaces of the vertical packaging box. After the upright packaging box is placed on the transfer conveyor belt, the box clamping and flipping component corresponds to the transfer conveyor belt, which allows the box clamping and flipping component to clamp and fix the transfer conveyor belt and the upright packaging box together. When the printing mechanism performs multi-sided printing on the upright packaging box, the box clamping and flipping component flips the transfer conveyor belt and the upright packaging box synchronously, so that the surface of the upright packaging box is flat and does not warp or deform. This allows the printing mechanism to form the code with various information on multiple surfaces of the upright packaging box through printing ink, without the need for manual flipping, which effectively improves the efficiency of multi-sided printing on the upright packaging box.

[0056] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent disclosure. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent disclosure should be determined by the appended claims.
