All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that in the description of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, and do not indicate or imply that the referred device or element must have a specific orientation, be configured in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Further, it will be appreciated that the dimensions of the various elements shown in the figures are not drawn to scale, for ease of description, and that the thickness or width of some layers may be exaggerated relative to other layers, for example.

It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one figure, it will not need to be further discussed or illustrated in detail in the description of the following figure.

As shown in fig. 1 to 4, the present invention provides a technical solution: a printing plate positioning device comprises a printing table 1, a conveyor 102 is arranged on the printing table 1, a printing device 3 is arranged on one side of the top of the printing table 1, limiting strips 103 are symmetrically arranged on the top of the printing table 1, a positioning structure 4 is arranged on the printing table 1 and close to the printing device 3, the positioning structure 4 comprises a vertical rod 406 fixed at the bottom of the printing table 1, the top end of the vertical rod 406 is fixedly connected with a second air cylinder 405, a baffle 401 is arranged at one end of the second air cylinder 405, the baffle 401 is in sliding connection with the limiting strips 103, a first air cylinder 402 is arranged in the middle of the baffle 401, an electric push rod 403 is arranged at the top of the first air cylinder 402, a sliding rod 404 is fixedly connected at one end of the electric push rod 403, the sliding rod 404 is in sliding connection with the limiting strips 103, the length of the sliding rod 404 is smaller than the distance between the limiting strips 103, through grooves for the sliding rod 404 and the baffle 401 to pass through are formed in the limiting strips 103, a control cabinet 2 is arranged beside the printing table 1, the printing equipment 3 and the positioning structure 4 are electrically connected with the control cabinet 2.

It should be noted that, the standard stroke of the electric push rod 403 is 400mm, the maximum thrust can reach 500N, and the no-load operation speed is 50mm/s, and it should be noted that the use of the electric push rod as the actuator not only can reduce the air supply devices and auxiliary devices required by the pneumatic actuator, but also can reduce the weight of the actuator. The pneumatic actuating mechanism needs to have certain air pressure in the whole control operation process, although an amplifier with small consumption can be adopted, the air consumption is still huge after long-term accumulation. The electric push rod actuating mechanism is adopted, power needs to be supplied when the control opening degree is changed, and power can not be supplied when the required opening degree is reached, so that the electric push rod actuating mechanism has the obvious energy-saving advantage compared with a pneumatic actuating mechanism in view of energy conservation.

Particularly, when printing the carton board, firstly, a worker places the carton board between the limiting strips 103 of the conveyor 102, the carton board moves along with the conveyor 102, meanwhile, the limiting strips 103 can effectively limit the carton box to prevent the carton box from deviating, when the carton board is a distance away from the printing device 3, the control cabinet 2 controls the second air cylinder 405 to be opened, the second air cylinder 405 pushes the baffle 401 to move, so that the baffle 401 is inserted into the limiting strips 103, at this time, the baffle 401 and the sliding rod 404 have a height difference, the baffle 401 is higher than the sliding rod 404, and at this time, the distance between the sliding rod 404 and the conveyor 102 is greater than the thickness of the carton box, so that the carton board can pass through the sliding rod 404 and move to the baffle 401, and the baffle 401 blocks the carton board, it is noted that the baffle 401 is in the same vertical plane with the side edge of the screen printing frame 307 at this time, can guarantee like this that carton board flushes on one side with screen printing frame 307 mutually, then switch board 2 opens first cylinder 402, first cylinder 402 shortens, and then drive electric putter 403 downstream, thereby make slide bar 404 and conveyer 102 contact, then open electric putter 403, electric putter 403 shortens, thereby promote carton board and baffle 401 and hug closely, make the four sides of carton board all flush with the four sides of screen printing frame 307 mutually, can guarantee like this that carton board can not squint, thereby with carton board spacing under screen printing frame 307, make the carton can both be just facing screen printing frame 307 at every turn, like this can be when printing, can both guarantee to print the same position of carton board, and then the condition emergence of skew can not appear, thereby the quality of product has been improved.
