[0002] Common color box printing is to place the raw material paperboard of the color box on the workbench for positioning and fixing, and then the printing device prints the paperboard.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0038] A printing process for packaging color box production, comprising the following steps:

[0039] The design step is to design the printing layout according to the impression pattern and text requirements of the color box.

[0040] The preparation step is to select appropriate printing paperboard as the printing material of the color box and prepare the printing ink.

[0041] The impression step is to start the printing equipment and adjust the parameters, put the printing paperboard into the printing equipment, and the printing equipment automatically prints the corresponding printing paperboard.

[0042] The drying step is to transport the printed paperboard to the drying equipment for drying until the ink on the paperboard is completely cured.

[0043] The quality inspection step is to inspect the printed color box to ensure that its appearance, pattern and characters meet the requirements.

[0044] REFERENCE Figures 1 to 11The utility model provides a printing process for packaging color box production, and the printing equipment includes first input mechanism 1, first impression station 2, output mechanism 3 and printing mechanism 4, first input mechanism 1 and output mechanism 3 are arranged at the both sides of first impression station 2 respectively and are communicated with first impression station 2, and first input mechanism 1 and output mechanism 3 are all conveyed through the conveyer belt, and first input mechanism 1 and output mechanism 3 are provided with guide frame 11 between first impression station 2 respectively, and guide frame 11 is arranged obliquely, so that when the paperboard enters first impression station 2 from first input mechanism 1 and the paperboard enters output mechanism 3 from first impression station 2, guide frame 11 guides the movement of the paperboard, printing mechanism 4 is arranged above first impression station 2, printing mechanism 4 can move towards the direction of first impression station 2, and it further includes impression base 21 and positioning frame 5.

[0045] Impression base 21 is arranged in the middle of first impression station 2, and a pushing mechanism 22 is arranged on the upper and lower movement of impression base 21 for pushing the paperboard out of impression base 21.

[0046] Positioning frame 5 is composed of three lifting plates 51 and a buffer plate 52 connected with each other, and a cube is formed between the three lifting plates 51 and the buffer plate 52, the positioning frame 5 is movably arranged on the impression base 21, one end of the positioning frame 5 is arranged close to the first input mechanism 1 with the buffer plate 52, the buffer plate 52 and the lifting plate 51 can slide relative to each other, and the sliding direction is up and down, and correspondingly, the upper end surface of the positioning frame 5 is higher than the upper end surface of the impression base 21 and lower than the lower end surface of the guide frame 11 on the first input mechanism 1 at the beginning, so that the paperboard can enter the positioning frame 5 better and be limited by the positioning frame 5, when the paperboard enters the positioning frame 5 from the first input mechanism 1, the three lifting plates 51 on the positioning frame 5 limit the paperboard in three directions, so that the paperboard 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, so that even if part of the paperboard is located on the buffer plate 52, the up and down vibration of the buffer plate 52 can also vibrate the paperboard into the positioning frame 5, so that the printing device enters the positioning frame 5 to press more accurately.

[0047] Specifically, when the printing starts, the paperboard is first placed on the first input mechanism 1, the first input mechanism 1 moves the paperboard towards the first impression station 2, when the paperboard moves to the guide frame 11, the paperboard enters the positioning frame 5 along the guide frame 11, at this time, the paperboard is limited by the three lifting plates 51, the paperboard gradually moves on the impression base 21, until the first input mechanism 1 is completely used to the force of the paperboard, at this time, the paperboard can enter the positioning frame 5 along the guide frame 11 or the paperboard has part of the buffer plate 52 on the guide frame 11, at this time, the positioning frame 5 moves towards the upper end, the lifting plate 51 and the buffer plate 52 move towards the upper end together, in the process of 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, the paperboard on the buffer plate 52 is vibrated to continue moving towards the impression base 21, the paperboard completely enters the positioning frame 5, that is, the paperboard completely covers the impression base 21, at this time, the printing mechanism 4 starts to move towards the impression base 21, so as to complete the impression of the paperboard, after the impression is completed, the printing mechanism 4 returns to the original position, and the positioning frame 5 moves towards the lower end until the upper end of the positioning frame 5 is lower than the upper end of the impression base 21, then the pushing mechanism 22 moves upwards, the pushing mechanism 22 is provided with a roller, the roller abuts against the paperboard, the rotating 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, the printed paperboard is output from the output mechanism 3, and the positioning frame 5 returns to the initial 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 can be moved out of the impression base 21 without being stuck on the output mechanism 3. In order to enable the paperboard to move better on the input mechanism and the output mechanism 3, the upper end of the input mechanism and the output mechanism 3 is provided with a limiting frame 13 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, the printing mechanism 4 is provided with a detection camera and a pressing mechanism, the detection camera is used to observe whether the paperboard is completely moved from the first input mechanism 1 to the guide plate, so as to drive the positioning frame 5 to move, the detection camera is prior art, which will not be described in detail here, and the pressing mechanism is also prior art, which is used to press the paperboard and push the paperboard out of the printing mechanism 4 to prevent adhesion, which will not be described in detail here.

[0049] By setting the positioning frame 5, the positioning frame 5 has three lifting plates 51 and a buffer plate 52 combination, the buffer plate 52 is close to the first input mechanism 1, so that the paperboard enters the positioning frame 5 from the first input mechanism 1, the positioning frame 5 rises, so that the lifting plate 51 and the buffer plate 52 are both raised, and in the process of movement, the buffer plate 52 vibrates, so that the paperboard is on the buffer plate 52 and the guide frame 11, the vibration of the buffer plate 52 can vibrate the paperboard into the positioning frame 5, so that the printing mechanism 4 prints more accurately, and after the positioning frame 5 moves downward to expose the paperboard, the pushing mechanism 22 can stably push the paperboard to the output mechanism 3.

[0050] With reference to Figures 1 to 3 Further, since the movement straight line of the printing mechanism 4 and the positioning frame 5 is in the same straight line only the opposite direction of movement, by setting the driving assembly 41, the driving assembly 41 includes a mounting table 411, a driving motor 412 and a driving rod 413, the mounting table 411 is arranged above the printing base, the printing mechanism 4 is arranged on the mounting table 411, a linkage rod 42 is arranged on the printing mechanism 4, the linkage rod 42 penetrates the mounting table 411, a sleeve 421 is sleeved on the linkage rod 42, the sleeve 421 is rotationally arranged on the mounting table 411, the sleeve 421 and the linkage rod 42 are threadedly connected, the driving rod 413 is connected with the output end of the driving motor 412, the driving rod 413 and the sleeve 421 are connected by a synchronous belt, one end of the lifting plate 51 penetrates the first impression table 2 and is provided with a linkage block 511, the driving rod 413 penetrates the linkage block 511, the driving rod 413 and the linkage block 511 are threadedly connected, so that the driving motor 412 drives the driving rod 413, 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 connected, the sleeve 421 and the linkage rod 42 are threadedly connected, so that the printing mechanism 4 and the positioning frame 5 can move relatively and oppositely, one driving source drives two mechanisms to move, which saves resources, in order to ensure that the printing mechanism 4 can move up and down, the printing mechanism 4 and the mounting table 411 are limited by a rod.

[0051] With reference to Figures 4 to 8When the lifting plate 51 is lifted, the buffer plate 52 will vibrate, so the end of the lifting plate 51 close to the buffer plate 52 is provided with a buffer block 512, the buffer plate 52 is provided with a buffer gap 521, the buffer block 512 is arranged in the buffer gap 521, the upper end of the buffer gap 521 is provided with a buffer hole 522, the buffer block 512 is provided with a buffer rod 513, the buffer rod 513 is arranged in the buffer hole 522, the buffer rod 513 is sleeved with a first elastic element 514, the two ends of the first elastic element 514 are fixedly arranged at the upper end of the buffer block 512 and the upper end of the buffer gap 521, the cooperation of 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 by the elastic force of the first elastic element 514, when the lifting plate 51 moves downward, the buffer plate 52 descends under the gravity, the elastic force of the first elastic element 514 plays a supporting role, and the first elastic element 514 is preferably a spring, which is convenient to use.

[0052] The end of the buffer plate 52 close to the inside of the positioning frame 5 is provided with a pushing block 533, a plurality of elastic plates 211 are vertically and spacedly arranged in the first stamping table 2, one curved protrusion 212 is arranged on the side of the elastic plate 211 close to the buffer plate 52, the pushing block 533 can abut against the protrusion 212, when the lifting plate 51 drives the buffer plate 52 to move upward, the pushing block 533 is limited by the protrusion 212, so that the buffer plate 52 is limited, and relative sliding occurs between the lifting plate 51 and the buffer plate 52, so the elastic force of the first elastic element 514 becomes larger and larger, until the elastic force provided by the first elastic element 514 can make the pushing block 533 push the protrusion 212 on the elastic plate 211 completely away from the pushing block 533, at this time, the buffer plate 52 has no upward moving resistance, the elastic force of the first elastic element 514 is released, and the buffer plate 52 vibrates up and down, and the paperboard is vibrated down. Correspondingly, the plurality of elastic plates 211 are vertically arranged, so that the buffer plate 52 can vibrate multiple times, thereby ensuring that the paperboard is vibrated down.

[0053] Correspondingly, the side edges of the buffer plates 52 of the two lifting plates 51 abut against each other, so the parts such as the buffer block 512, the buffer gap 521 and the first elastic element 514 are arranged in pairs.

[0054] Further, in order to prevent the elastic plate 211 from blocking the pushing block 533 when the buffer plate 52 descends, affecting the falling of the buffer plate 52 and causing the buffer plate 52 to vibrate again, the pushing block 533 is vertically arranged to have a certain length, and the vertical length of the pushing block 533 satisfies that when the buffer plate 52 rises to the highest point, the pushing block 533 still presses on the protrusions 212 of all the elastic plates 211.

[0055] Through setting the pushing block 533 and the elastic plate 211, the elastic support between the lifting plate 51 and the buffer plate 52 is realized, so that the lifting plate 51 can vibrate when rising, the buffer plate 52 does not need an additional driving part, the vibration of the buffer plate 52 is simple and fast, and resources are saved.

[0056] With reference to Figure 2 And Figure 8 In order to make the paperboard enter the positioning frame 5 better, the guide frame 11 needs to be arranged 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 further provided with the swing plate 12, the swing plate 12 is arranged at the lower end of the guide frame 11, the swing plate 12 is arranged to be inclined, the inclination angle of the swing plate 12 is consistent with that of the inclined frame of the guide frame 11, the lower end of the swing plate 12 is provided with the rotating rod 121, the two ends of the rotating rod 121 are rotatably provided with the reset blocks 122, the reset blocks 122 are fixedly arranged on the first input mechanism 1, the reset blocks 122 are provided with the coil spring, 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, and one 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, so that the paperboard is not clamped at the joint of the swing plate 12 and the buffer plate 52 after moving from the guide frame 11 to the swing plate 12 and then to the positioning frame 5.

[0057] When the buffer plate 52 rises, the buffer plate 52 pushes the swing plate 12, the swing plate 12 rotates with the rotating rod 121, when rotating, the reset blocks 122 have a reaction force on the rotating rod 121, the rising speed of the buffer plate 52 is slowed down, until the elastic force provided by the first elastic part 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, the elastic force provided by the first elastic part 514 is released, the buffer plate 52 vibrates once, the additional vibration promotes the falling of the paperboard, and when the buffer plate 52 falls, after the buffer plate 52 returns to the original position, the swing plate 12 abuts against the upper end of the buffer plate 52 again under the action of the coil spring in the reset blocks 122, the swing plate 12 and the buffer plate 52 are in close contact, which is beneficial to the entry of the next paperboard.

[0058] With reference to Figure 4When the positioning frame 5 is in the process of falling to prepare for the next paperboard, the three lifting plates 51 are not affected by the paperboard moving out, but if the buffer plate 52 continues to fall, a gap will appear between the buffer plate 52 and the swing plate 12 at the first input mechanism 1, and once the paperboard enters the gap, the paperboard will be stuck and cannot be moved out of the impression base 21. Therefore, a limiting plate 23 is arranged below the buffer plate 52, and the limiting plate 23 is arranged at the bottom end of the first impression table 2. The limiting plate 23 and the buffer plate 52 can abut, and when the limiting plate 23 and the buffer plate 52 abut, the buffer plate 52 returns to the initial position, that is, the upper end of the buffer plate 52 abuts against the swing plate 12. In this way, the paperboard cannot be moved out from the first input mechanism 1, and the continued falling of the lifting plate 51 keeps the elastic connection between the first elastic member 514 and the buffer plate 52, which does not affect the use between the subsequent lifting plate 51 and the buffer plate 52. The lifting plate 51 releases the remaining three sides of the impression platform, and any one side connected to the output mechanism 3 can push the paperboard out through the pushing mechanism 22.

[0059] Referring to Figure 9 The pushing mechanism 22 needs to be lifted, so a first pushing block 515 is arranged at the bottom end of the lifting plate 51 close to the end of the impression base 21. A slide rail 24 is arranged at the bottom end of the first impression table 2, and a sliding block 241 is movably arranged on the slide rail 24. A second pushing block 221 is arranged at the lower end of the pushing mechanism 22. Pressure inclined surfaces 2411 are arranged at both ends of the sliding block 241 close to the first pushing block 515 and the second pushing block 221. The two pressure inclined surfaces 2411 are mirror images arranged on both sides of the sliding block 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 falls, the first pushing block 515 on the lifting plate 51 pushes the pressure inclined surfaces 2411 on the sliding block 241, and the first pushing block 515 moves the sliding block 241 towards the second pushing block 221. When the sliding block 241 moves towards the second pushing block 221, the sliding block 241 starts to push the second pushing block 221 through the pressure inclined surfaces 2411 close to the second pushing block 221. The second pushing block 221 starts to rise under the pushing of the sliding block 241, so that the pushing mechanism 22 also rises. Until the pushing mechanism 22 abuts against the paperboard, when the lifting plate 51 starts to rise, the sliding block 241 is not subjected to the force of the first pushing block 515. The pushing mechanism 22 pushes the second pushing block 221 downwards through gravity, so that the pushing mechanism 22 returns to the original position, and the pushing mechanism 22 is not in abutment with the paperboard.

[0060] In order to make the pushing mechanism 22 rise more stably, the pushing mechanism 22 and the first impression table 2 are connected through the lifting rod 25, and the first impression table 2 is further provided with the limiting rod 26, and the limiting rod 26 penetrates through the second pushing block 221, so that the second pushing block 221 moves with the limiting rod 26, and the pushing mechanism 22 does not rotate randomly when rising, and the pushing mechanism 22 can stably pass through the impression base 21 and abut against the paperboard. The first pushing block 515 can be arranged on each of the plurality of lifting plates 51 to improve the stability of the pushing mechanism 22 rising.

[0061] Further, the first pushing block 515, the second pushing block 221 and the pressure receiving inclined surface 2411 are also provided with inclined surfaces, so that the pushing is more smooth.

[0062] By arranging the first pushing block 515, the sliding block 241 and the second pushing block 221, the lifting plate 51 can drive the pushing mechanism 22 to rise when descending, so that the pushing mechanism 22 does not need an additional driving source to drive, and does not need an additional detection mechanism to detect when to push the pushing mechanism 22, which is simple to operate and saves resources.

[0063] Referring to Figure 10 When the sliding block 241 moves on the sliding rail 24, it cannot affect the contact of the first pushing block 515 and the second pushing block 221, so a blocking plate is arranged at one end of the sliding rail 24 close to the first pushing block 515, and a moving groove 243 is arranged at the upper end of the sliding rail 24, and a moving block 2412 is arranged on the sliding block 241, and the moving block 2412 moves in the moving groove 243, and a second elastic member 244 is further arranged in the moving groove 243, and the two ends of the second elastic member 244 abut against the moving block 2412 and the moving groove 243 respectively, and the second elastic member 244 always pushes the moving block 2412 to move towards 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 towards the blocking block 242 at this time, so that the sliding block 241 abuts against the blocking block 242, so that the lower end of the second pushing block 221 is not supported, so that the pushing mechanism 22 can better descend, and when the sliding block 241 and the blocking block 242 abut against each other, the first pushing block 515 can stably push the pressure receiving inclined surface 2411 when the first pushing block 515 directly moves towards the sliding block 241 at this time.

[0064] Of course, in order to prevent the pushing mechanism 22 from descending too much, when the sliding block 241 and the blocking block 242 abut against each other, the second pushing block 221 still abuts against the pressure receiving inclined surface 2411 on the sliding block 241 at this time, so that the sliding block 241 supports the pushing mechanism 22.

[0065] During the whole movement, the first pushing block 515 will not exceed the pressure inclined surface 2411 of the sliding block 241, and the pressure inclined surface 2411 on the sliding block 241 will not be completely moved under the second pushing block 221, thereby preventing the first pushing block 515 and the second pushing block 221 from failing to return to the original position.

[0066] With reference to Figure 1 When the printing mechanism 4 is printing, the subsequent paperboard has to wait for a period of time, which reduces the work efficiency, so the second pressing table 6 is arranged on one side of the first input mechanism 1, the first input mechanism 1 is provided with a distributing mechanism 7, one side of the second pressing table 6 is provided with a second input mechanism 8, the distributing mechanism 7 is used for moving the paperboard on the first input mechanism 1 to the second input mechanism 8, and one side of the second pressing table 6 is also provided with the output mechanism 3, which is used for outputting the paperboard.

[0067] With reference to Figure 1 and 11 The first input mechanism 1 is provided with a discharge port 14 on the side close to the second pressing table 6, the distributing mechanism 7 comprises a distributing plate 71, which is rotationally arranged on the upper end of the first input mechanism 1 and arranged in the discharge port 14, the upper end of the rotating shaft of the distributing plate 71 is provided with a rotating motor, the rotating motor drives the distributing plate 71 to rotate, and the rotated distributing plate 71 is arranged obliquely on the first input mechanism 1, when the paperboard abuts against the distributing plate 71, the cooperation between the distributing plate 71 and the first input mechanism 1 moves the paperboard to one side of the discharge port 14, the second input mechanism 8 is arranged at the discharge port 14, so that the paperboard comes to the second input mechanism 8, the second input mechanism 8 drives the paperboard to continue to move, the output end of the second input mechanism 8 is connected with the second pressing table 6, so that the paperboard comes to the second pressing table 6 to be pressed, and of course, the discharge port 14 and the connection between the second input mechanism 8 and the second pressing table 6 are also provided with the guide frame 11.

[0068] In order to better convey the paperboard into the second input mechanism 8, the upper end of the second input mechanism 8 is provided with a first guide plate 81 and a second guide plate 82 at intervals, the first guide plate 81 is arranged close to the rotating position of the distributing 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, and the second guide plate 82 is arranged obliquely close to the end of the discharge port 14, so that when the paperboard abuts against the distributing plate 71, the distributing plate 71 and the first input mechanism 1 drive the paperboard to move towards the second input mechanism 8, the paperboard first contacts the first guide plate 81, the second input mechanism 8 continues to drive the paperboard to move, and the paperboard is inclined due to the distributing plate 71, the inclined paperboard 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 paperboard can enter the second pressing table 6 more stably.

[0069] The paperboard is separated by the separating plate 71, which is simple, and the paperboard can also be moved by a vacuum chuck and a mechanical hand.

[0070] With reference to Figure 11 In order to better discharge, the first pressing table 2 is arranged at the end of the first input mechanism 1, and the second pressing table 6 is perpendicular to the input direction of the first input mechanism 1, and the output direction of the output mechanism 3 of the second pressing table 6 is consistent with that of the first pressing table 2, so that the discharge directions of the first pressing table 2 and the second pressing table 6 are the same, and the receiving is also simple, for example, the printed paperboard can be completely transported by one discharge conveying belt, which is more simple.

[0071] Correspondingly, a plurality of separating mechanisms 7 can be arranged on the first input mechanism 1, so that a plurality of second pressing tables 6 can be arranged on the side of the first input mechanism 1, so that the printing time of a single printing mechanism 4 can be better utilized, and the printing efficiency is improved.

[0072] Moreover, by arranging the positioning frame 5, even if the second input mechanism 8 and the output mechanism 3 of the second pressing table 6 are in the same movement direction, the positioning frame 5 can also play a role in positioning the paperboard, and the paperboard input by the second input mechanism 8 will not be directly moved out of the second pressing table 6.

[0073] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
