[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] A printing process for producing packaging color boxes, comprising the following steps:

[0039] Design steps: design the printing layout according to the embossing pattern and text requirements of the color box.

[0040] Preparation steps: choose suitable printed cardboard as the printing material for the color box and prepare the printing ink.

[0041] In the printing step, the printing equipment is started and the parameters are adjusted, the printing cardboard is placed into the printing equipment, and the printing equipment automatically prints the printing cardboard.

[0042] In the drying step, the printed cardboard is transported to the drying equipment for drying until the ink on the cardboard is completely cured.

[0043] Quality inspection step: Check the printed color box to ensure that its appearance, pattern and text meet the requirements.

[0044] Reference Figures 1 to 11A printing process for producing packaging color boxes, the printing equipment includes a first input mechanism 1, a first stamping table 2, an output mechanism 3 and a printing mechanism 4, the first input mechanism 1 and the output mechanism 3 are respectively arranged on both sides of the first stamping table 2 and are connected to the first stamping table 2, the first input mechanism 1 and the output mechanism 3 are both transported by a conveyor belt, and a guide frame 11 is respectively arranged between the first input mechanism 1 and the output mechanism 3 and the first stamping table 2, the guide frame 11 is inclined, so that when the cardboard enters the first stamping table 2 from the first input mechanism 1 and the cardboard enters the output mechanism 3 from the first stamping table 2, the guide frame 11 guides the cardboard to move, the printing mechanism 4 is arranged above the first stamping table 2, the printing mechanism 4 can move toward the direction of the first stamping table 2, and also includes a stamping base 21 and a positioning frame 5.

[0045] The stamping base 21 is arranged in the middle of the first stamping platform 2 . A pushing mechanism 22 is arranged in the middle of the stamping base 21 for upward and downward movement, and is used to push the paperboard out of the stamping base 21 .

[0046] The positioning frame 5 is composed of three lifting plates 51 and a buffer plate 52 connected to each other. The three lifting plates 51 and the buffer plate 52 form a cube. The positioning frame 5 can be mounted on the stamping base 21 so as to move up and down. One end of the positioning frame 5 having the buffer plate 52 is arranged close to the first input mechanism 1. The buffer plate 52 and the lifting plate 51 can slide relative to each other. The sliding direction is up and down. Correspondingly, at the beginning, the upper end surface of the positioning frame 5 is higher than the upper end surface of the stamping base 21 and lower than the lower end surface of the guide frame 11 on the first input mechanism 1, so that the cardboard can better enter the positioning frame 5 and be positioned. The positioning frame 5 is limited. When the cardboard enters the positioning frame 5 from the first input mechanism 1, the three lifting plates 51 on the positioning frame 5 limit the three directions of the cardboard, so that the cardboard moves stably in the positioning frame 5, and the positioning frame 5 can move up and down. When the positioning frame 5 moves upward, the buffer plate 52 not only moves with the lifting plate 51, but also slides up and down relative to the lifting plate 51. In this way, even if part of the cardboard is located on the buffer plate 52, the up and down vibration of the buffer plate 52 can vibrate the cardboard into the positioning frame 5, so that the printing device can enter the positioning frame 5 for printing more accurately.

[0047] Specifically, when printing begins, the cardboard is first placed on the first input mechanism 1, and the first input mechanism 1 moves the cardboard toward the first stamping table 2. When the cardboard moves to the guide frame 11, the cardboard enters the positioning frame 5 along the guide frame 11. At this time, the cardboard is restricted by three lifting plates 51, and the cardboard gradually moves on the stamping base 21 until the first input mechanism 1 uses the force of the cardboard completely. At this time, the cardboard may enter the positioning frame 5 along the guide frame 11 or the cardboard may be partially placed on the guide frame 11 and the buffer plate 52. At this time, the positioning frame 5 moves toward the upper end, and the lifting plate 51 and the buffer plate 52 move toward the upper end together. During the movement, the buffer plate 52 and the lifting plate 51 slide relative to each other, so that the buffer plate 52 vibrates relative to the lifting plate 51, and the cardboard placed on the buffer plate 52 is vibrated and continues to move toward the stamping base 21, and the cardboard completely enters the positioning frame 5. The printing mechanism 4 starts to move toward the imprinting base 21 at this time, so as to complete the imprinting of the paperboard. After the imprinting is completed, the printing mechanism 4 returns to its original position, and the positioning frame 5 moves toward the lower end until the upper end surface of the positioning frame 5 is lower than the upper end surface of the imprinting base 21, and then the pushing mechanism 22 moves upward. A roller is provided on the pushing mechanism 22, and the roller abuts against the paperboard. The rotation direction of the roller is consistent with the direction of the output mechanism 3, so that the rotation of the roller can push the paperboard into the output mechanism 3, and the imprinted paperboard is output from the output mechanism 3, and the positioning frame 5 returns to the starting position. Of course, the output width of the output mechanism 3 is greater than the width of the positioning frame 5, so that the paperboard will not be stuck on the output mechanism 3 when it is moved out from the imprinting base 21. In order to enable the paperboard to move better on the input mechanism and the output mechanism 3, a limiting frame 13 is provided on the upper end of the input mechanism and the output mechanism 3 to guide the movement of the paperboard.

[0048] In order to ensure that the positioning frame 5 and the printing mechanism 4 can move accurately, a detection camera and a clamping mechanism are provided on the printing mechanism 4. The detection camera is used to observe whether the cardboard is completely moved from the first input mechanism 1 to the guide plate, thereby driving the positioning frame 5 to move. The detection camera is a prior art and will not be elaborated on in detail here. The clamping mechanism is also a prior art and is used to press the cardboard and push it out of the printing mechanism 4 to prevent adhesion. It will not be elaborated on in detail here.

[0049] By setting the positioning frame 5, the positioning frame 5 is composed of three lifting plates 51 and a buffer plate 52, and the buffer plate 52 is arranged close to the first input mechanism 1, so that the cardboard enters the positioning frame 5 from the first input mechanism 1, and the positioning frame 5 is lifted, so that the lifting plates 51 and the buffer plate 52 both move upward, and in the process of movement, the buffer plate 52 vibrates, so that even if the cardboard is on the buffer plate 52 and the guide frame 11, the vibration of the buffer plate 52 can vibrate the cardboard into the positioning frame 5, so that when the printing mechanism 4 is printing, the cardboard is completely in the positioning frame 5, the printing mechanism 4 is more accurate, and after the positioning frame 5 moves downward to expose the cardboard, the pushing mechanism 22 can stably push the cardboard to the output mechanism 3.

[0050] Reference Figures 1 to 3 : Further, since the movement lines of the printing mechanism 4 and the positioning frame 5 are on the same straight line but the movement directions are opposite, a driving component 41 is set, and the driving component 41 includes a mounting platform 411, a driving motor 412 and a driving rod 413. The mounting platform 411 is set above the printing base, and the printing mechanism 4 is movably set on the mounting platform 411. A linkage rod 42 is set on the printing mechanism 4, and the linkage rod 42 penetrates the mounting platform 411. A sleeve 421 is sleeved on the linkage rod 42, and the sleeve 421 is rotatably set on the mounting platform 411. The sleeve 421 and the linkage rod 42 are threadedly connected, and the driving rod 413 is connected to the output end of the driving motor 412. A synchronous belt is connected between the driving rod 413 and the sleeve 421. The connection is set, and one end of the lifting plate 51 passes through the first stamping table 2 and is provided with a linkage block 511. The driving rod 413 passes through the linkage block 511. The driving rod 413 and the linkage block 511 are connected by a thread, so that the driving motor 412 drives the driving rod 413, and the driving rod 413 drives the sleeve 421 and the linkage block 511 to move. The driving rod 413 and the linkage block 511 are threadedly transmitted, and the sleeve 421 and the linkage rod 42 are threadedly transmitted, so that the printing mechanism 4 and the positioning frame 5 can perform relative movement and opposite movement. One driving source drives the movement of two mechanisms, saving resources. In order to ensure that the printing mechanism 4 can perform lifting movement, the printing mechanism 4 and the mounting table 411 are limited by rods.

[0051] Reference Figures 4 to 8When the lifting plate 51 is lifted, the buffer plate 52 will vibrate, so a buffer block 512 is provided at one end of the lifting plate 51 close to the buffer plate 52, a buffer notch 521 is provided on the buffer plate 52, the buffer block 512 is arranged in the buffer notch 521, a buffer hole 522 is provided at the upper end of the buffer notch 521, a buffer rod 513 is provided on the buffer block 512, the buffer rod 513 is movably arranged in the buffer hole 522, a first elastic member 514 is sleeved on the buffer rod 513, and the first elastic member 514 is sleeved on the first elastic member 514. The two ends of the first elastic member 514 are fixedly arranged at the upper end of the buffer block 512 and the upper end of the buffer notch 521. The cooperation between the buffer rod 513 and the buffer hole 522 ensures that the buffer plate 52 will not deviate when it moves up and down. When the lifting plate 51 moves upward, the lifting plate 51 drives the buffer plate 52 to move upward through the elastic force of the first elastic member 514. When the lifting plate 51 moves downward, the buffer plate 52 descends with gravity, and the elastic force of the first elastic member 514 plays a supporting role. The first elastic member 514 is preferably a spring for easy use.

[0052] The push block 533 is provided at one end of the buffer plate 52 facing the inner side of the positioning frame 5, and a plurality of spring plates 211 are arranged vertically at intervals in the first stamping table 2. A curved protrusion 212 is provided on the side of the spring plate 211 facing the buffer plate 52, and the push block 533 can abut against the protrusion 212. When the lifting plate 51 drives the buffer plate 52 to move upward, the push block 533 is restricted by the protrusion 212, so that the buffer plate 52 is restricted, and relative sliding occurs between the lifting plate 51 and the buffer plate 52. Therefore, the elastic force of the first elastic member 514 becomes larger and larger until the elastic force provided by the first elastic member 514 enables the push block 533 to completely push the protrusion 212 on the spring plate 211 away from the push block 533. At this time, the buffer plate 52 has no resistance to upward movement, and the elastic force of the first elastic member 514 is released, so that the buffer plate 52 vibrates up and down, and the paperboard is vibrated down. Correspondingly, through the plurality of spring plates 211 arranged vertically, the buffer plate 52 can vibrate multiple times, thereby ensuring that the paperboard is vibrated down.

[0053] Correspondingly, the sides of the buffer plates 52 of the two lifting plates 51 are abutted, so the corresponding buffer blocks 512, buffer notches 521 and first elastic members 514 are arranged in pairs.

[0054] Furthermore, in order to ensure that the spring plate 211 does not block the push block 533 from affecting the falling of the buffer plate 52 and causing the buffer plate 52 to vibrate again when the buffer plate 52 descends, the push block 533 is provided with a certain length in the vertical direction. The vertical length of the push block 533 satisfies that when the buffer plate 52 rises to the highest point, the push block 533 is still pressed on the protrusions 212 of all the spring plates 211.

[0055] By setting the pushing block 533 and the spring plate 211, elastic support is provided between the lifting plate 51 and the buffer plate 52, so that when the lifting plate 51 is rising, the buffer plate 52 can vibrate through the contact between the pushing block 533 and the spring plate 211, without the need for additional driving parts, and the vibration of the buffer plate 52 is simple and fast, saving resources.

[0056] Reference Figure 2 and Figure 8 In order to make the cardboard enter the positioning frame 5 better, the guide frame 11 needs to be placed above the buffer plate 52, and the end of the guide frame 11 is arranged close to the inner side of the buffer plate 52, so the first input mechanism 1 is also provided with a swing plate 12, which is arranged at the lower end of the guide frame 11, and the swing plate 12 is inclined. The inclination angle of the swing plate 12 is consistent with the inclination angle of the guide frame 11, and the lower end of the swing plate 12 is provided with a rotating rod 121, and the two ends of the rotating rod 121 are rotatably provided. The reset block 122 is fixedly arranged on the first input mechanism 1. A coil spring is arranged inside the reset block 122. The coil spring drives the rotating rod 121 to rotate, so that the lower end of the swing plate 12 abuts against the lower end of the guide frame 11. The end of the swing plate 12 close to the buffer plate 52 abuts against the buffer plate 52 and is arranged close to the inner side of the buffer plate 52. In this way, the cardboard moves from the guide frame 11 to the swing plate 12 and then moves into the positioning frame 5, and the cardboard will not be stuck at the intersection of the swing plate 12 and the buffer plate 52.

[0057] When the buffer plate 52 rises, the buffer plate 52 pushes the swing plate 12, and the swing plate 12 rotates with the rotating rod 121. During the rotation, the reset block 122 has a reaction force on the rotating rod 121, and the rising speed of the buffer plate 52 is slowed down until the elastic force provided by the first elastic member 514 is greater than the force provided by the coil spring. At this time, the buffer plate 52 pushes the swing plate 12 out of the upper end of the buffer plate 52, and the elastic force provided by the first elastic member 514 is released, and the buffer plate 52 vibrates once. The additional vibration promotes the falling of the cardboard, and when the buffer plate 52 descends, after the buffer plate 52 returns to its original position, the swing plate 12 is under the action of the coil spring in the reset block 122, and the swing plate 12 again abuts against the upper end of the buffer plate 52, and the swing plate 12 and the buffer plate 52 are in close contact, which is conducive to the entry of the next cardboard.

[0058] Reference Figure 4: When the positioning frame 5 continues to fall after printing to prepare for the unloading of the cardboard, the descent of the three lifting plates 51 does not affect the removal of the cardboard. However, if the buffer plate 52 continues to descend, a gap will appear between the buffer plate 52 and the swing plate 12 at the first input mechanism 1. Once the cardboard enters the gap, the cardboard will be stuck and cannot be removed from the imprinting base 21. Therefore, a limit plate 23 is further provided below the buffer plate 52. The limit plate 23 is provided at the bottom end of the first imprinting table 2, and the limit plate 23 and the buffer plate 52 can abut against each other. When the limit plate 23 and the buffer plate 52 are in contact, the buffer plate 52 returns to the initial position, that is, the upper end of the buffer plate 52 is in contact with the swing plate 12, so that the cardboard will not move out from the first input mechanism 1, and the lifting plate 51 continues to descend, and the first elastic member 514 and the buffer plate 52 maintain an elastic connection, which does not affect the subsequent use of the lifting plate 51 and the buffer plate 52. The lifting plate 51 releases the remaining three sides of the imprinting platform, and any side is selected to connect to the output mechanism 3, and the cardboard can be pushed out through the pushing mechanism 22.

[0059] Reference Fig. 9 : The pushing mechanism 22 needs to be lifted, so a first pushing block 515 is arranged at one end of the bottom of the lifting plate 51 close to the stamping base 21, a slide rail 24 is arranged at the bottom of the first stamping table 2, a slider 241 is movably arranged on the slide rail 24, and a second pushing block 221 is arranged at the lower end of the pushing mechanism 22. Both ends of the slider 241 close to the first pushing block 515 and the second pushing block 221 are provided with pressure inclined surfaces 2411, and the two pressure inclined surfaces 2411 are mirror-imaged on both sides of the slider 241. The pressure inclined surfaces 2411 abut against the first pushing block 515 and the second pushing block 221. In this way, when the lifting plate 51 is lowered, the first pushing block 515 on the lifting plate 51 pushes the pressure inclined surfaces on the slider 241. The first pushing block 515 presses the inclined surface 2411, and moves the slider 241 toward the second pushing block 221. When the slider 241 moves toward the second pushing block 221, the slider 241 starts to push the second pushing block 221 through the pressed inclined surface 2411 close to the second pushing block 221. The second pushing block 221 starts to rise under the push of the slider 241, so that the pushing mechanism 22 also rises until the pushing mechanism 22 abuts against the cardboard. When the lifting plate 51 starts to rise, the slider 241 is no longer subjected to the force of the first pushing block 515, and the pushing mechanism 22 pushes the second pushing block 221 downward by gravity, so that the pushing mechanism 22 returns to its original position, and the pushing mechanism 22 no longer abuts against the cardboard.

[0060] In order to make the pushing mechanism 22 rise more stably, the pushing mechanism 22 and the first stamping table 2 are connected by a lifting rod 25. A limiting rod 26 is also provided on the first stamping table 2. The limiting rod 26 penetrates the second pushing block 221. In this way, the second pushing block 221 moves with the limiting rod 26. The pushing mechanism 22 will not rotate at will when it rises. The pushing mechanism 22 can stably pass through the stamping base 21 and abut against the cardboard. The first pushing block 515 can be provided on multiple lifting plates 51 to improve the stability of the pushing mechanism 22 when it rises.

[0061] Furthermore, an inclined surface is also provided between the first pushing block 515 , the second pushing block 221 and the pressure inclined surface 2411 , so that the pushing is smoother.

[0062] By setting the first pushing block 515, the slider 241 and the second pushing block 221, the lifting plate 51 can drive the pushing mechanism 22 to rise when it descends, so that the rise of the pushing mechanism 22 does not require an additional driving source, and does not require an additional detection mechanism to detect when the pushing mechanism 22 is pushed. The operation is simple and resources are saved.

[0063] Reference Fig.10 When the slider 241 moves on the slide rail 24, it cannot affect the contact with the first push block 515 and the second push block 221, so a blocking plate is provided at one end of the slide rail 24 close to the first push block 515, a moving groove 243 is provided at the upper end of the slide rail 24, a moving block 2412 is provided on the slider 241, and the moving block 2412 is movably set in the moving groove 243. A second elastic member 244 is also provided in the moving groove 243, and the two ends of the second elastic member 244 respectively abut the moving block 2412 and the moving groove 243, and the second elastic member 244 always pushes the moving block 241 2 moves toward one side of the blocking block 242, so that when the first pushing block 515 does not push the sliding block 241, the second elastic member 244 pushes the moving block 2412 and the sliding block 241 to move toward the blocking block 242, so the sliding block 241 abuts against the blocking block 242, so that the lower end of the second pushing block 221 has no support, so that the pushing mechanism 22 can be better descended, and when the sliding block 241 abuts against the blocking block 242, when the first pushing block 515 directly moves toward the sliding block 241, the first pushing block 515 can stably push the pressed inclined surface 2411.

[0064] Of course, in order to prevent the pushing mechanism 22 from descending too much, when the slider 241 abuts against the blocking block 242 , the second pushing block 221 still abuts against the pressure inclined surface 2411 on the slider 241 , so that the slider 241 supports the pushing mechanism 22 .

[0065] During the entire movement, the first push block 515 will not exceed the pressure inclined surface 2411 of the slider 241, and the pressure inclined surface 2411 on the slider 241 will not completely move under the second push block 221, thereby preventing the first push block 515 and the second push block 221 from being unable to return to their original positions.

[0066] Reference Figure 1 : When the printing mechanism 4 is printing, the subsequent cardboard has to wait for a while, which reduces the working efficiency. Therefore, a second stamping station 6 is provided. The second stamping station 6 is arranged on one side of the first input mechanism 1. A material dividing mechanism 7 is arranged on the first input mechanism 1. A second input mechanism 8 is arranged on one side of the second stamping station 6. The material dividing mechanism 7 is used to move the cardboard on the first input mechanism 1 to the second input mechanism 8. An output mechanism 3 is also arranged on one side of the second stamping station 6. The output mechanism 3 is used to output the cardboard.

[0067] Reference Figure 1 and 11 : A discharge port 14 is provided on one side of the first input mechanism 1 close to the second stamping table 6, and the dividing mechanism 7 includes a dividing plate 71, which is rotatably arranged at the upper end of the first input mechanism 1 and arranged in the discharge port 14, and a rotating motor is arranged at the upper end of the rotating shaft of the dividing plate 71, and the rotating motor drives the dividing plate 71 to rotate. The rotated dividing plate 71 is tilted on the first input mechanism 1, and when the cardboard and the dividing plate 71 abut, the cooperation between the dividing plate 71 and the first input mechanism 1 moves the cardboard toward one side of the discharge port 14, and the second input mechanism 8 is arranged at the discharge port 14, so that the cardboard comes to the second input mechanism 8, and the second input mechanism 8 drives the cardboard to continue moving, and the output end of the second input mechanism 8 is connected with the second stamping table 6, so that the cardboard comes to the second stamping table 6 for stamping. Of course, the discharge port 14 and the connection between the second input mechanism 8 and the second stamping table 6 are also provided with a guide frame 11.

[0068] In order to better convey the cardboard into the second input mechanism 8, the upper end of the second input mechanism 8 is spaced apart with a first guide plate 81 and a second guide plate 82. The first guide plate 81 is arranged near the rotating position of the dividing plate 71, and the second guide plate 82 is arranged at the end of the discharge port 14 away from the first guide plate 81. The second guide plate 82 is inclined at the end near the discharge port 14. In this way, when the cardboard and the dividing plate 71 are in contact, the dividing plate 71 and the first input mechanism 1 drive the cardboard to move toward the second input mechanism 8. The cardboard first contacts the first guide plate 81, and the second input mechanism 8 continues to drive the cardboard to move. Because the dividing plate 71 has a certain inclination, the inclined cardboard is clamped by the first guide plate 81 and the second guide plate 82 under the guidance of the inclined position of the second guide plate 82, so that the cardboard can enter the second stamping table 6 more stably.

[0069] The paperboards are separated by the separating plate 71, which is relatively simple. Of course, the paperboards can also be moved by machines such as vacuum suction cups and manipulators.

[0070] Reference Fig.11 : In order to better discharge the materials, the first stamping station 2 is arranged at the end of the first input mechanism 1, the second stamping station 6 is perpendicular to the input direction of the first input mechanism 1, and the output direction of the second stamping station 6 and the output mechanism 3 of the first stamping station 2 are consistent. In this way, the discharge directions of the first stamping station 2 and the second stamping station 6 are the same, and the material collection is also simpler. For example, all the printed cardboards can be transported by a discharge conveyor belt, which is simpler.

[0071] Correspondingly, a plurality of material dividing mechanisms 7 can be arranged on the first input mechanism 1, so that a plurality of second stamping tables 6 can be arranged on the side of the first input mechanism 1, thereby making better use of the printing time of a single printing mechanism 4 and improving printing efficiency.

[0072] Furthermore, by providing the positioning frame 5, even if the second input mechanism 8 and the output mechanism 3 of the second stamping station 6 are in the same moving direction, the positioning frame 5 can still play the role of positioning the cardboard, and the cardboard input by the second input mechanism 8 will not be directly moved out of the second stamping station 6.

[0073] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
