[0033] Figures 1-4 A color box surface intelligent high-speed printing device is shown, comprising: a conveying unit 1, which is sequentially provided with a printing unit 2 and a drying unit 3 inside, further comprising:

[0034] The conveying unit 1 is provided with a feeding unit 4 and a recycling unit 5 at both ends respectively, and the middle section of the conveying unit 1 is provided with a rotatable adjusting shaft 11, and the adjusting shaft 11 is provided with an adjusting knob 12 at one end outside the conveying unit 1;

[0035] The elastic guide plate 6 is semicircular and is arranged on both sides of the inlet end of the conveying unit 1;

[0036] The cleaning unit 7 is located in the conveying unit 1, and the cleaning unit 7 is arranged between the elastic guide plate 6 and the printing unit 2;

[0037] The two sets of limiting plates 8 are slidably arranged on the adjusting shaft 11 and are arranged between the elastic guide plate 6 and the drying unit 3 and close to both sides of the conveying unit 1.

[0038] Working principle:

[0039] Before starting the operation, the operator first determines the length of the paperboard, and rotates the adjusting knob 12 to make the two sets of limiting plates 8 slide close to each other on the adjusting shaft 11 (in use, the adjusting shaft 11 is connected to the two sides of the conveying unit 1 through bearings at both ends, so that the rotation of the adjusting shaft 11 only produces rotation by itself and does not affect the conveying unit 1), until the distance between the two limiting plates 8 is greater than the predetermined distance of the length of the paperboard (the length of the paperboard itself n+1-3cm), then the operator stacks the paperboard to be printed into the feeding unit 4 in turn;

[0040] When the operation starts, the conveying unit 1 is started by an external device, the feeding unit 4 lowers the paperboard to the conveying unit 1, the paperboard is aligned to the middle by the elastic guide plates 6 on both sides of the inlet end after entering the conveying unit 1, the paperboard passing through the elastic guide plates 6 enters between the two sets of limiting plates 8, and the dust, paper scraps or other impurities on the surface of the paperboard are removed by the cleaning unit 7 to ensure the printing quality and avoid incomplete printing. The distance between the two sets of limiting plates 8 limits the position of the paperboard that can move horizontally, thereby limiting the paperboard and avoiding the possible deviation of the conveying unit 1 during operation, so as to meet the requirement that the area to be scribbled on the paperboard is opposite the printing unit 2, the printed paperboard enters the drying unit 3 to make the pigment dry quickly, and finally leaves from the other end of the conveying unit 1, and is collected in the recycling unit 5 for subsequent cutting operation;

[0041] Among them, ① the elastic guide plate 6 has a certain elasticity, which can buffer and guide the entering paperboard, so that the paperboard can enter the conveying track of the conveying unit 1 more accurately, avoiding the deviation or paper jam of the paperboard due to improper entering angle;

[0042] ②In actual use, in order to make the paperboard enter the conveying unit 1 more smoothly and save time, the structure of the feeding unit 4 includes: a box body 41 with a support frame, which is provided with an upper notch 42 and a lower notch 43 at the top and bottom respectively, and an auxiliary roller 44 is arranged on the side of the box body 41 opposite the lower notch 43; a pressing machine 45 is arranged at the top of the inner side of the box body 41; a plurality of rollers 46 are arranged in parallel at the inner bottom of the box body 41;

[0043] The operator stacks the paperboard to be printed into the box 41 through the upper notch 42 (keeping the surface to be printed facing upward), when the paperboard in the box is stacked to a certain height, the downward press 45 is started by an external device to apply downward pressure to the paperboard, so that the gap between the paperboard in the box 41 is shortened and kept flat, and the conveying unit 1 starts to work, the paperboard in the box 41 is driven to move forward through the cooperation of the upper and lower groups of rollers 46 and auxiliary rollers 44, and the paperboard leaves the lower notch 43 of the box 41 and enters the conveying unit 1; since the groups of rollers 46 are distributed in parallel, the paperboard can be uniformly subjected to force, ensuring the stability of the paperboard during conveying, and the arrangement of the groups of rollers 46 can assist the paperboard to slide out instead of being hard taken out by the conveying end of the conveying unit 1, so as to avoid the abrasion caused by the mutual friction between the paperboard and the contact part in the box 41;

[0044] In summary, the device can limit the paperboard for the first time through the elastic guide plate 6, limit the paperboard during cleaning and printing through the two groups of limiting plates 8, avoid pattern printing errors caused by paperboard deviation, the added cleaning unit 7 can clean the paperboard area to be scribbled, avoid incomplete pattern printing caused by impurities, and the added feeding unit 4 can reduce the time-consuming and laborious repeated work of manually placing the paperboard into the conveying unit 1, and improve the overall production efficiency.

[0045] The drying unit 3 arranged in the device can quickly realize the drying work of the paperboard, quickly dry the ink, and avoid the ink bleeding or smearing before entering the recycling unit 5.

[0046] As in the above scheme, the upper end of the drying unit 3 is provided with a filter box 31.

[0047] Working principle:

[0048] In actual use, the drying unit 3 can adopt air drying or lamp lighting, so that the ink can be quickly dried, and the ink bleeding or smearing can be avoided before entering the recycling unit 5;

[0049] In which, the ink volatilization will produce a large amount of peculiar smell, which will cause a threat to the production environment and the health of the workers, in order to reduce the pollution of the production environment, a filter box 31 is arranged on the drying unit 3, the volatile gas is sucked into the lower end suction port, the harmful gas such as ink volatilization is adsorbed by the internal filter medium (such as activated carbon), and the filtered gas is discharged from the upper end exhaust hole 32, reducing the pollution to the environment.

[0050] As in the above scheme, the middle section of the adjusting shaft 11 is sequentially provided with a right-handed thread section 13, a non-thread section and a left-handed thread section 14;

[0051] The structure of the single limiting plate 8 comprises: an upper horizontal rod 83, which is provided with a threaded through hole 81, and opposite upper horizontal rods 83 are bolted on the threads on both sides of the adjusting shaft 11 through the threaded through holes 81 respectively;

[0052] A lower horizontal rod 84, which is provided with a plurality of rack protruding parts 82 in parallel at the lower end of the place where it is attached to the side of the paperboard, and vertical rods 85 are arranged on both sides of the top surface of the lower horizontal rod 84, and the other ends of the vertical rods 85 are connected with the upper horizontal rod 83.

[0053] Working principle:

[0054] Before starting work, the operator first determines the length of this batch of paperboard, and rotates the adjusting knob 12 to make the two sets of limiting plates 8 slide close to each other on the adjusting shaft 11. The specific way is:

[0055] Since the single upper horizontal rod 83 is provided with a threaded through hole 81, and opposite upper horizontal rods 83 are bolted on the threads (right-handed threaded section 13 and left-handed threaded section 14, and the threads in the threaded through hole 81 match the corresponding threaded sections) on both sides of the adjusting shaft 11 through the threaded through holes 81 respectively, when the adjusting shaft 11 rotates, the limiting plates 8 connected to the right-handed threaded section 13 and the limiting plates 8 connected to the left-handed threaded section 14 will move towards or away from each other along the adjusting shaft 11, thereby adjusting the distance between the two sets of limiting plates 8 to adapt to paperboards of different widths, so that the limiting plates 8 can limit the paperboard during conveying;

[0056] Since the upper horizontal rod 83 drives the lower horizontal rod 84 to move through the vertical rods 85, in order to avoid shaking and walking during the movement, a through hole is arranged at both ends of the upper horizontal rod 83 in actual use, and a sliding rod 86 is connected; at the same time, the sliding rod 86 is fixed at both ends on the conveying unit 1, so that the upper horizontal rod 83 can slide horizontally on the sliding rod 86 during movement, and provides a certain supporting force for the vertical rods 85 and the lower horizontal rod 84 to prevent left and right deviation;

[0057] Among them, ① the distance between the two limiting plates 8 is greater than the predetermined distance of the length of the paperboard (the length of the paperboard itself n+1-3cm), which is to avoid completely attaching to the paperboard to cause stopping on the conveying unit 1 without moving, and to provide a certain movable deviation distance to avoid paper jamming;

[0058] ② The rack protruding part 82 (the predetermined protruding size is 1mm-1.5mm) contacts the side of the paperboard, and the rack structure can better adapt to the irregular concave-convex of the side of the paperboard, ensuring that the paperboard always remains in the appropriate position during conveying;

[0059] In actual use, a reference scale 121 (such as the actual distance between the two limiting plates 8 after each rotation of a predetermined angle) can be added on the side of the adjusting knob 12 opposite the outer wall of the conveying unit 1, and an observation window 122 can be added at the lower end of the adjusting knob 12, so that the operator can more intuitively adjust the size each time through the cooperation of the scale 121 and the observation window 122, thereby improving reliability and practicality.

[0060] As in the above scheme, the structure of the cleaning unit 7 includes:

[0061] A plurality of groups of roller brushes 71 are arranged in a horizontal matrix and rotatably mounted on a support 72 between the elastic guide plate 6 and the printing unit 2.

[0062] A vertical telescopic rod 73 is mounted at the top end of the conveying unit 1, and the output end of the vertical telescopic rod 73 is connected to the top end of the support 72.

[0063] A dust suction port 74 is provided on the support 72 and located above the plurality of groups of roller brushes 71.

[0064] Working principle:

[0065] When the paperboard is conveyed to the cleaning unit 7, the roller brushes 71 begin to rotate, and the rotation direction of the roller brushes 71 cooperates with the conveying direction of the paperboard, and the dust, paper scraps, impurities and the like attached to the surface of the paperboard are scraped off through the contact friction between the bristles of the roller brushes 71 and the surface of the paperboard.

[0066] After the roller brushes 71 scrape off the impurities on the surface of the paperboard, the dust suction port 74 is connected to the dust suction device through the dust suction pipeline 75, and the suction force generated by the dust suction device timely sucks away the impurities adhering to the bristles of the roller brushes 71, thereby avoiding the reattachment of the impurities to the surface of the paperboard or the scattering of the impurities in the conveying unit 1 to affect the normal operation of other components, ensuring the cleaning effect of the cleaning unit 7 and the working environment of the entire conveying unit 1.

[0067] Among them, ① the roller brushes 71 are arranged in multiple groups and in a horizontal matrix, which can ensure more comprehensive cleaning of the impurities on the surface of the paperboard;

[0068] ② The vertical telescopic rod 73 can adjust the height of the support 72 according to the thickness of the paperboard or the actual cleaning requirements, thereby adjusting the contact distance between the roller brushes 71 and the surface of the paperboard, and ensuring the cleaning effect. In actual use, the vertical telescopic rod 73 can be selected to move up and down by a threaded rod sliding or an electric push rod.

[0069] ③Suction port 74 is arranged at the upper end of the roller brush 71, not directly in contact with the paperboard, mainly to prevent the paperboard from blocking the suction port 74, because some paperboard is too light, if the suction port 74 is directly used to clean the surface of the paperboard, it may cause the light paperboard to be also adsorbed by the suction force and block the suction port 74, there is a risk of causing the whole device to be unable to work normally, so the device first carries the impurities by the brush head of the roller brush 71, and then the suction port 74 cleans the impurities adhered to the bristles, ensuring smooth operation of the cleaning unit 7;

[0070] ④In actual use, the position of the conveying unit 1 relative to the cleaning unit 7 is provided with an opening window 76 structure, the operator can replace or clean the suction port 74 or the roller brush 71 by opening the opening window 76, and the opening window 76 is provided with a transparent window 77, one side of the transparent window 77 is provided with a reference scale 78 (such as the distance between the roller brush 71 and the conveying belt on the conveying unit 1), the operator can realize the vertical movement of the cleaning unit 7 by cooperating the transparent window 77 with the reference scale 78, improve the reliability and practicality.

[0071] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, it can be fully applied to various fields suitable for the present application, and for those skilled in the art, other modifications can be easily realized, therefore, the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
