Description

Technical Field

[0001] This utility model relates to the field of date coding technology for packaging bags, specifically to a date coding device for stand-up pouches. Background Technology

[0002] As a key consumable material for product packaging in industries such as food, daily necessities, and pharmaceuticals, the coding of information such as production date and batch number on the surface of packaging tape is an important part of the product quality traceability system. With the increasing automation of packaging production lines, higher requirements are placed on the stability, accuracy, and efficiency of date coding devices.

[0003] Traditional date coding devices use a fixed structure to mount the ink tape, relying solely on initial manual tension adjustment. This lack of dynamic adjustment capability means that tape wear during production alters the tape's tension. Insufficient tension leads to curling and misalignment, causing blurred or missing characters; excessive tension breaks the tape, interrupting coding. Both scenarios reduce coding pass rates and increase defective products and rework costs. Therefore, there is an urgent need to design a date coding device for stand-up packaging tape to solve these problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown in the figure, the present invention provides a date coding device for stand-up packaging tape, including a mounting frame 1, a coding machine 2 mounted on the mounting frame 1, a mounting plate 21 mounted on one side of the coding machine 2, a coding device 4 mounted below one side of the mounting plate 21, a plurality of guide rods 9 mounted on the mounting plate 21, an ink tape 7 mounted on the guide rods 9, a tension adjustment assembly 3 mounted on the mounting plate 21, the tension adjustment assembly 3 including a servo motor 31 and a tension sensor 32 mounted on the other side of the mounting plate 21, a tension sensing roller 33 and a swing arm 34 mounted on one side of the mounting plate 21, one end of the tension sensing roller 33 mounted on the tension sensor 32, one end of the swing arm 34 mounted on the output shaft of the servo motor 31, and an adjustment roller 35 mounted on one end of the swing arm 34.

[0028] In this embodiment, a coding machine 2 is provided on the mounting frame 1, and a mounting plate 21 is provided on one side of the coding machine 2. The mounting plate 21 serves to support and fix various components. Several guide rods 9 are provided on the mounting plate 21 to ensure that the ink belt 7 remains stable during operation and does not shift or wrinkle, thereby ensuring printing quality. The guide rods 9 are provided with the ink belt 7, which is the key material for printing.

[0029] Specifically, a tension adjustment assembly 3 is provided on the mounting plate 21. The tension adjustment assembly 3 includes a servo motor 31 and a tension sensor 32 located on the other side of the mounting plate 21. The servo motor 31 can provide stable and controllable power output, and the tension sensor 32 can sense the tension changes of the ink belt 7 in real time. A tension sensing roller 33 and a swing arm 34 are respectively provided on one side of the mounting plate 21.

A slide rail 48, a telescopic cylinder 46 and a spring 44 are respectively provided on the sliding mounting plate 47. A sliding block 49 is slidably connected to the slide rail 48.

[0031] Specifically, a thermal transfer printhead 45 is provided on one side of the sliding block 49. The thermal transfer printhead 45 is located on top of the ink belt 7 to ensure accurate ink transfer during the printing process. One end of the spring 44 is provided on the sliding block 49, and its elasticity can provide a certain buffer and pressure adjustment for the thermal transfer printhead 45. One end of the telescopic rod of the telescopic cylinder 46 is provided on the sliding block 49. By controlling the telescopic movement of the telescopic cylinder 46, the contact pressure and distance between the thermal transfer printhead 45 and the ink belt 7 and the printing paper 8 can be controlled to achieve the printing effect.

[0038] Specifically, a winding motor 61 is provided on the back of the mounting plate 21. The output shaft of the winding motor 61 is connected to the ink tape recycling roll 6. Driven by the winding motor 61, the used ink tape 7 can be evenly wound onto the ink tape recycling roll 6 at a stable speed, ensuring that the ink tape 7 is recycled smoothly and orderly, and avoiding the accumulation or messy entanglement of the ink tape 7.

[0039] Working steps: 1. After installing the mounting bracket 1, the ink tape 7 is passed through the guide rod 9, tension sensing roller 33 and adjusting roller 35 in sequence. Then, the ink tape take-up roll 6 is rotated to tighten the ink tape 7. The printing paper 8 to be coded is passed through the guide roller 11, the top of the support plate 12 and the bottom of the guide roller 2 13 in sequence. Then, the sliding block 49 and the thermal print head 45 are moved up and down by the telescopic cylinder 46 to start printing the date or barcode, etc. The sliding block 49 can be automatically returned to the center by the spring 44.

[0040] Second, the tension of the ink belt 7 is detected by the tension sensing roller 33 and the tension sensor 32, and then the tension of the ink belt 7 is changed by the swing arm 34 controlled by the servo motor 31.

[0041] Third, the drive motor 421 drives the transmission gear 42 and the transmission belt 422 to rotate, which in turn drives the sliding mounting plate 47 to move left and right, so that the coding device 4 can print different specifications and models.
