Description

Technical Field

[0001] This utility model relates to the field of outer-coat inkjet printer technology, specifically to a product positioning structure for an outer-coat inkjet printer. Background Technology

[0002] Outer packaging inkjet printers are devices that print identification information on product packaging. They are primarily used to print production dates, shelf lives, barcodes, QR codes, and other information on product packaging. This information not only helps consumers understand the basic condition of the product but also provides businesses with important evidence for tracing product quality. The printer stores specialized inkjet inks, including solvent-based and water-based inks. Through digital control, the ink is precisely ejected from the printhead. Employing micro-piezoelectric technology, the nozzles can be quickly opened and closed to form clear letters and patterns. It is also equipped with sensors that automatically identify the product position passing through the printhead, ensuring accurate marking while significantly improving production efficiency. However, existing technologies have the following problems:

[0003] In the outsourced production process, during the process of conveying products to the inkjet printer to print the three-phase code after they are boxed, belt fluctuations or product slippage can cause the three-phase information to be misaligned or even missed. This affects product quality to some extent. Although it can be handled by wiping with alcohol and then reprinting, due to the limitations of many product packaging materials, it is impossible to clean and reuse them by wiping with alcohol, and they can only be scrapped. This not only greatly increases the packaging material loss rate and production costs, but also adds to the workload of the staff in this position. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a product positioning structure for an external wire marking printer, including a product box conveying platform 1, with a front and rear conveyor belt located at the top center of the product box conveying platform 1.

[0024] The bottom rectangular array of the product box conveying platform 1 is fixedly installed with four supporting legs 11, the top left side of the product box conveying platform 1 is provided with an adjusting mechanism 5, the top of the adjusting mechanism 5 is provided with a product box positioning mechanism 4, the top of the conveying belt 2 is uniformly provided with a plurality of product boxes 6, the product box positioning mechanism 4 comprises an extension mounting plate 41, the top right side of the extension mounting plate 41 is provided with a product box baffle 42, the bottom front side of the product box baffle 42 is movably installed with a pulley 43, the right side of the pulley 43 is overlapped with the left side of one of the plurality of product boxes 6, the right side of the product box conveying platform 1 is provided with a bracket 3, the outer wall of the bracket 3 is fixedly installed with an extension plate 31, the left end rear side of the extension plate 31 is fixedly installed with a code jet head 32 of a code jet machine, the code jet head 32 is located at the top of one of the plurality of product boxes 6, the top right side of the product box conveying platform 1 is fixedly installed with two front and rear distributed L-shaped brackets 12, the left end of the two L-shaped brackets 12 is fixedly installed with a limiting long plate 13, the bottom of the limiting long plate 13 is overlapped with the top of the conveying belt 2, the right side of the plurality of product boxes 6 is all overlapped with the left side of the limiting long plate 13, and the pulley 43 is located at the left side of the limiting long plate 13.

[0025] When the product box 6 is conveyed forward by the conveying belt 2, when the position deviates during the conveying process, when the product box 6 passes the right side of the product box baffle 42, the product box 6 can be tightly attached to the left side surface of the limiting long plate 13 at the left end of the L-shaped bracket 12 by the sliding extrusion of the pulley 43, so that it stably passes below the code jet head 32 of the code jet machine, and the top of the product box 6 can be jetted by the code jet machine cooperating with the code jet head 32 at the left rear end of the extension plate 31, so that the product box 6 can be jetted in the deviated state, and the jetting success rate and stability are improved.

[0026] As shown in Figure 4 The extension mounting plate 41 is provided with an up-down through connecting hole 411, the product box baffle 42 is provided with an up-down through positioning hole 421, the positioning hole 421 is up-down aligned with the connecting hole 411, the inner circle of the connecting hole 411 and the positioning hole 421 is penetrated with a fixing bolt 422, and the outer wall bottom of the fixing bolt 422 is threadedly installed with a nut 423.

[0027] The nut 423 can be rotated and detached by a wrench, so that the product box baffle 42 can be rotated at an angle, so that it is closer to the product box 6 or farther away from the product box 6, and after adjustment, the nut 423 is rotated and tightened until it abuts against the bottom of the extension mounting plate 41, so that the fixing of the product box baffle 42 is completed, and the product box 6 of different widths can be conveniently positioned.

[0028] As shown in Figure 5As shown, the adjustment mechanism 5 includes a first vertical plate 51 and a second vertical plate 52. The first vertical plate 51 is located in front of the second vertical plate 52. Both the first vertical plate 51 and the second vertical plate 52 are fixedly installed on the top left side of the product box conveying platform 1. An adjustment threaded rod 53 is movably installed on the rear side of the first vertical plate 51. The rear end of the adjustment threaded rod 53 extends through to the rear side of the second vertical plate 52 and is fixedly installed with an adjustment knob 54. A moving block 55 is threadedly installed on the outer wall of the adjustment threaded rod 53. The top of the moving block 55 is fixedly connected to the bottom left side of the extension mounting plate 41. A limiting slide rod 56 is fixedly installed between the opposite surfaces of the first vertical plate 51 and the second vertical plate 52. The limiting slide rod 56 is located on the left side of the adjustment threaded rod 53. The moving block 55 is slidably connected to the limiting slide rod 56.

[0029] When the overall length of product box 6 is relatively long, in order to position and straighten the complete product box 6 in advance...

[0030] To straighten the product box 6, the adjustment knob 54 can be rotated, which will drive the adjustment threaded rod 53 at the rear end of the upright plate 51 to rotate. The threaded connection between the moving block 55 and the adjustment threaded rod 53 can control the extension mounting plate 41 at the top of the moving block 55 to move the product box baffle 42 backward as a whole. The sliding connection between the moving block 55 and the limit slide rod 56 maintains the stability of the movement, so that the product box 6 can be straightened and positioned in advance by passing the pulley 43 at the right end of the product box baffle 42, which can better accommodate longer product boxes 6.

[0031] The working principle of the product positioning structure of this outsourced inkjet printer will be explained in detail below.

[0032] like Figures 1-5 As shown, during use, the product box 6 is conveyed forward by the conveyor belt 2. When a positional shift occurs during conveying, as the product box 6 passes the right side of the product box baffle 42, the sliding and pressing action of the pulley 43 causes the product box 6 to adhere tightly to the left side surface of the limiting plate 13 at the left end of the L-shaped bracket 12 at a horizontal position. This allows it to stably pass under the inkjet printer head 32. Using an external inkjet printer in conjunction with the inkjet printer head 32 on the left side of the rear end of the extension plate 31, the top of the product box 6 can be inkjet-printed, thus preventing the product box 6 from receiving inkjet printing while in a shifted state and improving inkjet printing efficiency. Success rate and stability are ensured. The nut 423 can be rotated and removed using a wrench, allowing the product box baffle 42 to be rotated to move closer to or further away from the product box 6. After adjustment, the nut 423 is tightened until it abuts against the bottom of the extension mounting plate 41, thus fixing the product box baffle 42. This facilitates positioning product boxes 6 of different widths. When the overall length of the product box 6 is long, to ensure proper positioning and straightening of the complete product box 6 beforehand, the adjusting knob 54 can be rotated, thereby actuating the adjusting threads at the rear end of the upright plate 51.

[0033] The rod 53 rotates, and the extension mounting plate 41 at the top of the moving block 55 can be controlled to move the product box baffle 42 as a whole backward by the threaded connection of the moving block 55 and the adjusting threaded rod 53, and the stability of the movement is maintained by the sliding connection of the moving block 55 and the limiting slide rod 56, so that the product box 6 can pass through the pulley 43 at the right end of the product box baffle 42 in advance to be straightened and positioned, and longer product boxes 6 can be more adapted.

[0034] The above has made a detailed description of the utility model in general, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
