[0022] Hereinafter, an embodiment of the box positioning structure for marking on an inkjet printer of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4The present invention shows a box positioning structure for marking on a printer according to an embodiment of the present invention, comprising a fixed plate 2 fixedly connected to the rear side of the top of a conveyor 1, a fixed frame 8 fixedly connected to the left side of the top of the conveyor 1, a liftable baffle plate 9 provided on the right side of the fixed frame 8, an electric telescopic rod 10 fixedly installed on the right side of the fixed frame 8, the output end of the electric telescopic rod 10 is fixedly connected to the top of the baffle plate 9, the top of the fixed plate 2 is rotatably connected to a rotating frame 3, the inner cavity of the rotating frame 3 is provided with a positioning assembly 4, and the positioning assembly 4 includes a sliding plate 4 slidably connected to the inner cavity of the rotating frame 3 1. The top and bottom of the inner cavity of the rotating frame 3 are fixedly connected to the limiting guide rail 6. The top and bottom of the sliding plate 41 are provided with a limiting slide 7 adapted to the limiting guide rail 6. The limited guide rail 6 and the limiting slide 7 are used in conjunction with each other to limit and guide the sliding plate 41, so that the sliding plate 41 can maintain a stable linear motion during the movement, so that the box can be accurately squeezed and limited. The front end of the sliding plate 41 is fixedly connected to the positioning card plate 42. Both sides of the inner cavity of the positioning card plate 42 are rotatably connected to a plurality of rubber rollers 11. A stepper motor 43 is fixedly installed on the right side of the top of the rotating frame 3. Gears 44 are rotatably connected on both sides of the inner cavity of the rotating frame 3. The output shaft of the stepper motor 43 passes through the inner cavity of the rotating frame 3 and is fixedly connected to the gear 44 at the rear side. A plurality of teeth 45 are fixedly connected on both sides of the sliding plate 41. The gears 44 mesh with the teeth 45. An angle adjustment component 5 is provided on the left side of the top of the fixed plate 2. The angle adjustment component 5 includes a fixed sleeve 51 fixedly connected to the front end of the left side of the rotating frame 3. The inner cavity of the fixed sleeve 51 is slidably connected to the limit pin 52. There are multiple rings distributed on the top of the fixed plate 2. A limiting hole 53 is opened at its top, and a spring 54 is provided on the surface of the limiting pin 52. The top and bottom ends of the spring 54 are welded to the fixing sleeve 51 and the limiting pin 52 respectively. Through the setting of the angle adjustment component 5, the limiting pin 52 and the limiting hole 53 are used in conjunction to limit and lock the rotating frame 3, so that the rotating frame 3 can be stably fixed on the top of the fixed plate 2 to prevent deflection. At the same time, under the elastic force of the spring 54, the limiting pin 52 can be firmly engaged in the inner cavity of the limiting hole 53, further improving the reliability of limiting the rotating frame 3.

[0024] Working principle: When the present invention is used, the user conveys the box body horizontally through the conveyor 1, and then the electric telescopic rod 10 opens and pushes the baffle plate 9 downwards. The baffle plate 9 moves downwards under the thrust to block the box body. At this time, under the blocking of the baffle plate 9 and the transmission action of the conveyor 1, one side of the box body fits with the surface of the baffle plate 9, and then the stepper motor 43 is turned on and drives the gear 44 to rotate. Since the gear 44 and the teeth 45 are in meshing state, the sliding plate 41 slides out and drives the alignment card 42 to squeeze on a corner of the box body, pushing the box body to the left and front side for alignment, and then the inkjet printer sprays the code. After the code is sprayed, the electric The telescopic rod 10 drives the baffle plate 9 to rise, and the conveyor 1 continues to transport the box to the left. The baffle plate 9 can be reset under the reverse rotation of the stepper motor 43. According to the different sizes of boxes, the user can adjust the movement trajectory of the sliding plate 41 to ensure that the positioning card plate 42 can be accurately squeezed on the corner surface of the box. When adjusting, it is only necessary to lift the limit pin 52 so that the limit pin 52 is disengaged from the inner cavity of the current limit hole 53, and then rotate the rotating frame 3 to rotate the sliding plate 41. After the adjustment is completed, release the limit pin 52, and the spring 54 resets to drive the limit pin 52 to be inserted into the inner cavity of the current limit hole 53.

[0025] To sum up: the box positioning structure for marking on the inkjet printer intercepts the box being transported by the conveyor 1 through the coordinated use of the fixed frame 8, the material baffle 9 and the electric telescopic rod 10, and then the box is squeezed and aligned through the coordinated use of the rotating frame 3 and the positioning component 4. At the same time, the extrusion angle can be adjusted through the coordinated use of the fixed plate 2 and the angle adjustment component 5, so as to achieve the purpose of fast and accurate alignment and adjustable alignment angle, and adapt to boxes of different sizes.
