[0023] As Figs. 1-3 As shown in the accompanying drawings, the present application provides a laser ink-jet printer with positioning function, which comprises a belt conveyor 10 and a control cabinet, further comprising an ink-jet mechanism 20, an adjusting mechanism 30, a positioning structure and a driving mechanism 50.

[0024] The ink-jet mechanism 20 comprises a first horizontal plate 21 and a laser ink-jet printer body 22. The first horizontal plate 21 is fixedly installed on the rack of the belt conveyor 10 and is fixedly connected with the rack of the belt conveyor 10 through the first reinforcing rib. The laser ink-jet printer body 22 is fixedly installed on the first horizontal plate 21.

[0025] The adjusting mechanism 30 comprises a second cross plate 31, a guide rail 32, a sliding base 33, a first cylinder 34 and a guide rod 35. The second cross plate 31 is fixedly installed on the rack of the belt conveyor 10 and is fixedly connected with the rack of the belt conveyor 10 through a second reinforcing rib. Preferably, the second cross plate 31 and the first cross plate 21 are respectively located on the two sides of the belt conveyor 10. The guide rail 32 is fixedly installed on the second cross plate 31 along the running direction of the belt conveyor 10. The sliding base 33 is arranged on the guide rail 32 and is slidably connected with the guide rail 32. The first cylinder 34 is arranged in the transverse direction and is electrically connected with the control cabinet. The cylinder body of the first cylinder 34 is fixedly connected with the second cross plate 31, and the piston rod of the first cylinder 34 is fixedly connected with the sliding base 33. The first cylinder 34 is used for controlling the movement of the sliding base 33 on the guide rail 32. The guide rod 35 is fixedly installed on the sliding base 33 along the running direction of the belt conveyor 10.

[0026] The number of the positioning mechanisms 40 is two, and the two positioning mechanisms 40 are respectively arranged on the two sides of the guide rod 35. The positioning mechanism 40 comprises a sliding block 41, a movable rod 42, a positioning plate 43 and a second cylinder 44. The sliding block 41 is slidably connected with the guide rod 35. The movable rod 42 is arranged in the transverse direction and is slidably connected with the sliding block 41. The extending direction of the movable rod 42 is perpendicular to the running direction of the belt conveyor 10. The positioning plate 43 is fixedly installed on the movable rod 42. The second cylinder 44 is arranged in the transverse direction and is electrically connected with the control cabinet. The cylinder body of the second cylinder 44 is fixedly connected with the sliding block 41, and the piston rod of the second cylinder 44 is fixedly connected with the positioning plate 43. The second cylinder 44 is used for controlling the movement of the movable rod 42.

[0027] The driving mechanism 50 is used for controlling the two positioning mechanisms 40 to move close to or away from each other.

[0028] In the initial state, the second cylinder 44 is in the contracted state, and the positioning plate 43 is away from the conveying belt of the belt conveyor 10, so as to avoid affecting the normal conveying of the articles.

[0029] In the working process of the utility model, the conveying belt of the belt conveyor 10 intermittently moves the articles to the positions directly below the working positions of the laser code inkjet printer body 22, and then the laser code inkjet printer body 22 sequentially performs the code inkjet operation on the articles.

[0030] When the object is not precisely moved to the position right below the working position of the laser ink-jet printer body 22, the control cabinet controls the two second air cylinders 44 to extend, and the corresponding positioning plates 43 are moved forward until the two positioning plates 43 are respectively located on the two sides of the object. Then the driving mechanism 50 is started, and the two positioning mechanisms 40 are moved close to each other until the object is clamped. Then the control cabinet controls the first air cylinder 34 to start, and the slide 33 is moved by the first air cylinder 34, so that the two positioning mechanisms 40 move the object synchronously until the object is intermittently moved to the position right below the working position of the laser ink-jet printer body 22. Finally, each part is reset to the initial state.

[0031] In the working process of the utility model, the adjusting mechanism 30, the positioning structure and the driving mechanism 50 work together, can move the object on the conveyor belt of the belt conveyor 10, and move the object to the position right below the working position of the laser ink-jet printer body 22, so as to ensure the precision of the ink-jet operation.

[0032] In an embodiment, the driving mechanism 50 comprises a bidirectional screw rod 51 and a motor 52. The bidirectional screw rod 51 passes through the two positioning plates 43 along the running direction of the belt conveyor 10, and both ends of the bidirectional screw rod 51 are rotationally connected with the slide 33. The screw directions of the threads on both ends of the bidirectional screw rod 51 are opposite, and both ends of the bidirectional screw rod 51 are threadedly connected with the two positioning plates 43 respectively. The motor 52 is fixedly installed on the slide 33 and electrically connected with the control cabinet, and the motor 52 is used for controlling the rotation of the bidirectional screw rod 51.

[0033] When the driving mechanism 50 works, the control cabinet controls the motor 52 to start, and the motor 52 drives the bidirectional screw rod 51 to rotate. Since the screw directions of the threads on both ends of the bidirectional screw rod 51 are opposite, under the action of the guide rod 35, the two sliding blocks 41 move close to or away from each other, so that the two positioning mechanisms 40 move close to or away from each other until the object is clamped.

[0034] The driving mechanism 50 has a simple structure, and is convenient for production, manufacturing and maintenance.

[0035] In an embodiment, a plurality of photoelectric sensors 11 are fixedly installed on the rack of the belt conveyor 10, and the plurality of photoelectric sensors 11 are arranged at intervals along the running direction of the belt conveyor 10. The photoelectric sensors 11 are electrically connected with the control cabinet.

[0036] When the object passes through the photoelectric sensor 11, the plurality of photoelectric sensors 11 can sequentially detect the conveying speed and the specific position of the object, so as to facilitate the subsequent accurate movement of the object to the position right below the working position of the laser ink-jet printer body 22.

[0037] In an embodiment, a limiting groove 45 corresponding to the object is formed in the inner side wall of the positioning plate 43, so as to better adapt to the shape of the object.

[0038] In one embodiment, the inner wall of the limiting groove 45 is fixedly installed with a rubber pad, which protects the object.
