Description

Technical Field

[0001] This application relates to the field of coding machine technology, and in particular to a coding machine automatic plane switching mechanism. Background Technology

[0002] Existing coding machines are typically designed for labeling and coding on flat product surfaces. However, in actual production, products come in various shapes, including both flat and cylindrical. The coding plane of existing machines is usually fixed flat, making it unsuitable for cylindrical products. Therefore, when using existing coding machines to apply labels to cylindrical products, the codes on the labels often fail to align accurately, resulting in poor label adhesion and impacting product quality and production efficiency. To address this, an automatic plane switching mechanism for the coding machine is proposed. Utility Model Content

[0003] To address the problem that when using existing coding machines to affix labels to cylindrical products, the codes on the labels often cannot be accurately aligned, resulting in poor label affixing effects and impacting product quality and production efficiency, this application provides an automatic plane switching mechanism for coding machines.

[0004] The automatic planar switching mechanism for the coding machine provided in this application adopts the following technical solution:

[0005] The automatic planar switching mechanism of the coding machine includes a base, a slide, a coding mechanism, and a winding mechanism. The slide and the winding mechanism are both disposed on the upper surface of the base. The slide is located between the unwinding end and the rewinding end of the winding mechanism. The winding mechanism is used to feed the label paper. The coding mechanism is located on the upper part of the slide. The lower part of the slide is rotatably connected to a printing platform via a first motor. An arc surface adaptation mechanism is provided on one side of the printing platform, which enables the label paper to be used for arc surface coding.

[0006] Preferably, the coding mechanism includes a first electric push rod fixedly installed on the top of the slide block. The first electric push rod is vertically arranged, and the telescopic end of the first electric push rod faces downward and is connected to the coding device.

[0007] Preferably, the arc surface adaptation mechanism includes a mounting plate, a lifting plate, and a printing roller. The mounting plate is fixedly installed on the surface of the printing platform.

The two sets of pressure rollers are located on both sides of the printing roller, and the central axes of the printing roller and the pressure roller are arranged parallel to each other.

[0008] Preferably, guide rollers are provided on both sides of the outer surface of the printing platform, and arc-shaped grooves adapted to the guide rollers are opened on both sides of the outer surface of the printing platform, and the guide rollers are rotatably installed inside the corresponding arc-shaped grooves.

[0009] Preferably, the winding mechanism includes vertical plates fixedly installed on both sides of the upper surface of the base. Each vertical plate is rotatably connected to a connecting rod. A second motor is fixedly installed on the surface of one set of vertical plates. The output shaft of the second motor is fixedly connected to the connecting rod.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0019] This application discloses an automatic planar switching mechanism for a coding machine, including a base 1, a slide 2, a coding mechanism, and a winding mechanism. The slide 2 and the winding mechanism are both disposed on the upper surface of the base 1. The slide 2 is located between the unwinding end and the rewinding end of the winding mechanism. The winding mechanism is used to feed label paper. The coding mechanism is located on the upper part of the slide 2. The lower part of the slide 2 is rotatably connected to a printing platform 6 via a first motor 3. An arc surface adaptation mechanism is provided on one side of the printing platform 6, which enables the label paper to be used for arc surface coding.

[0020] In this embodiment, by setting the first motor 3 to work in conjunction with the printing platform 6, the printing platform 6 can be driven to rotate, so that the flat or curved surface adaptation mechanism of the printing platform 6 is set upward. The label paper is then passed through the printing platform 6 by the winding mechanism, so that the label paper can adapt to flat or curved surface coding, thereby enabling the label paper to adapt to the flat or curved surface of the product.

[0021] It should be noted that the first motor 3 has a self-locking function, which can maintain its current rotational position after power failure or loss of power. It achieves the self-locking function through an internal mechanical self-locking device (such as a ratchet mechanism or electromagnetic brake) to ensure that it will not rotate unexpectedly due to external force or gravity in the event of power failure or malfunction.

[0022] Furthermore, the coding mechanism includes a first electric push rod 4 fixedly installed on the top of the slide block 2. The first electric push rod 4 is vertically arranged, with its telescopic end facing downward and connected to the coding device 5.

[0023] In this embodiment, the height of the coding device 5 can be adjusted by setting the first electric push rod 4, so that the coding device 5 can code clearly and quickly.

[0024] In this embodiment, the coding device 5 is an inkjet coding machine: ink is sprayed onto the product surface through nozzles to form text or patterns. It has high flexibility and the ability to change the printed content in real time. The structure and control system of the inkjet printer are existing technologies and will not be described in detail here. The model of the coding device 5 is not required.

[0025] Furthermore, the curved surface adaptation mechanism includes a mounting plate 13, a lifting plate 14, and a printing roller 12. The mounting plate 13 is fixedly installed on the surface of the printing platform 6. Both ends of the lifting plate 14 are connected to the printing platform 6 through a second electric push rod 15. Both ends of the lifting plate 14 are rotatably connected to pressure rollers 17. The two sets of pressure rollers 17 are located on both sides of the printing roller 12, and the central axes of the printing roller 12 and the pressure rollers 17 are parallel.

[0026] In this embodiment, when it is necessary to adapt the label paper to the curved surface for printing, firstly, the second electric push rod 15 is used to drive the lifting plate 14 and the pressure roller 17 to move above the printing roller 12. Then, the winding mechanism is used to make the label paper pass between the pressure roller 17 and the printing roller 12. Then, the second electric push rod 15 is used to drive the lifting plate 14 and the pressure roller 17 to move below the printing roller 12, so that the label paper partially adapts to the shape of the printing roller 12 and forms a curved surface shape.

[0027] Furthermore, guide rollers 16 are provided on both sides of the outer surface of the printing platform 6, and arc-shaped grooves adapted to the guide rollers 16 are opened on both sides of the outer surface of the printing platform 6. The guide rollers 16 are rotatably installed inside the corresponding arc-shaped grooves.

[0028] In this embodiment, during flat coding, the first motor 3 drives the printing platform 6 to rotate so that its flat surface faces upward, and then the label paper passes over the upper surface of the printing platform 6. The guide roller 16 plays a transition role when the label paper passes over the edge of the printing platform 6, so as to facilitate the smooth feeding of the label paper.

[0029] Furthermore, the winding mechanism includes vertical plates 7 fixedly installed on both sides of the upper surface of the base 1. Each vertical plate 7 is rotatably connected to a connecting rod 8. A second motor 11 is fixedly installed on the surface of one set of vertical plates 7. The output shaft of the second motor 11 is fixedly connected to the connecting rod 8. A winding roller 9 is movably sleeved on the outer surface of each connecting rod 8. One side of the winding roller 9 is a closed end, and a connecting bolt 10 is inserted into the closed end of each winding roller 9. Each end of the connecting rod 8 is provided with a threaded hole 18 that matches the connecting bolt 10. The connecting bolt 10 can be screwed into or out of the threaded hole 18.

[0030] In this embodiment, the roller 9 is used to wind or unwind label paper. The beginning and end of the label paper can be glued to the surface of the roller 9. The connecting bolt 10 can fix the roller 9 and the connecting rod 8 relative to each other. The second motor 11 can drive the connecting rod 8 and the roller 9 to rotate, thereby conveying the label paper.
