[0026] Example 1

[0027] like Figure 1 - Figure 5 As shown, a ribbon printer with a simple structure and compact appearance includes a mounting base 1, a winding assembly, a printing assembly 2, a printing base plate 3, a ribbon 4, a fixing base 5, a slide plate 6, and a screw 7. The winding assembly includes a supply reel 8, a take-up reel 9, a take-up power source 10, a buffer rocker arm 11, a pulley 12, and a plurality of transition rollers 13. The printing assembly 2 includes a printing cylinder 21 and a printing head 22 connected to each other. The mounting base 1 is a block-shaped structure used to support and install the winding assembly. The supply reel 8 and take-up reel 9 are rotatably mounted on the mounting base 1 respectively. The take-up power source 10 is connected to the take-up reel 9 and can drive the take-up reel 9 to rotate. The buffer rocker arm 11 is rotatably mounted on the mounting base 1. One end of the buffer rocker arm 11 is elastically connected to the take-up reel 9 via a spring, and the other end is rotatably connected to the transition roller 13. The printing cylinder 21 and print head 22 are mounted on a slide 6. The steel surface of the print head 22 faces the printing base 3, facilitating the passage of labels and ribbon 4. The printing base 3 is a flat plate, fixed perpendicularly to a fixed base 5. The ribbon 4 is wound into a disk and stored on a supply reel 8. One end of the ribbon 4 is unwound from the supply reel 8, passing over a plurality of transition rollers 13, parallel to the print head 22 and the printing base 3, then around a take-up pulley 12, and finally recovered on a take-up reel 9. The fixed base 5 is located on the side of the mounting base 1. The slide 6 is a plate structure that is slidably connected to the fixed base 5. The bottom of the printing assembly 2 is fixed to the slide 6 via a connecting plate. The screw 7 is threadedly connected to the slide 6. Rotation of the screw 7 causes the slide 6 to slide on the fixed base 5, thereby causing the printing assembly 2 to translate relative to the printing base 3. This allows the position of the printing assembly 2 to be adjusted according to the desired location on the label, enhancing ease of use and adaptability.

[0028] In this embodiment, the printer further includes an adjustment knob 14, which is fixed to the end of the screw 7 and located on the side of the fixing base 5. By manually turning the adjustment knob 14, the screw 7 rotates, thereby driving the slide 6 to slide on the fixing base 5; this makes adjustment more convenient.

[0029] In this embodiment, the fixing base 5 includes a fixing plate 51 and a mounting plate 52, which are secured together by bolts for easy assembly and disassembly. The fixing plate 51 is a square plate with a sliding plate 6 slidably connected to the fixing plate 51. The mounting plate 52 is an L-shaped plate with several connecting holes. One end of the mounting plate 52 is secured to the printing base 3 via connecting holes and bolts, while the other end of the mounting plate 52 is secured to the fixing plate 51 via connecting holes and bolts. An adjustment knob 14 is located on the side of the mounting plate 52. By adjusting the fixed position of the mounting plate 52 on the fixing plate 51, the distance between the printing base 3 and the print head 22 can be adjusted, making printing more convenient and more adaptable.

[0030] In this embodiment, the take-up power source 10 is a take-up cylinder, which is connected to the take-up reel 9 through a transmission mechanism, and the transmission mechanism can be a rack and pinion mechanism; the take-up reel 9 is driven to rotate by the take-up power source 10, so that the ribbon 4 is recovered.

[0031] In actual application, the winding assembly, the printing assembly 2, the printing base plate 3, and the ribbon 4 are on the same straight line, or in other words, the four are aligned and arranged on the same horizontal plane, so that the printing head 22 can print neatly.

[0032] In actual use, when a label passes through the printer's print head 22 and briefly stops between the printing base 3, the printing cylinder 21 will push the print head 22 to move, passing the font on the print head 22 through the ribbon 4 and printing the font on the label. Then, the take-up power source 10 drives the take-up reel 9 to rotate and retract the ribbon 4, while the supply reel 8 releases a new ribbon 4, which is convenient for printing the font on the next label. At this point, a complete process is completed. When the position of the printing assembly 2 is to be adjusted, the adjustment knob 14 is manually turned to drive the screw 7 to rotate, thereby driving the slide 6 to slide on the fixed seat 5, and then driving the printing assembly 2 to translate to the appropriate position relative to the printing base 3.

[0033] The beneficial effects of this embodiment are as follows: by providing the fixing base 5, slide plate 6, screw 7, etc., the printer can adjust the position of the printing assembly 2 according to the desired printing position on the label, making it more convenient to use and more adaptable. By adjusting the fixed position of the mounting plate 52 on the fixing plate 51, the printer can adjust the distance between the printing base 3 and the printing head 22, making printing more convenient and more adaptable. Furthermore, the device has a simple overall structure, a compact appearance, is easy to disassemble, assemble, manufacture, and process, and is low in cost.

[0034] Example 2

[0035] The difference between this embodiment and the first embodiment is that this embodiment does not have an adjustment knob 14 and is not adjusted manually. Instead, a stepper motor is connected to the screw 7 through a coupling. The stepper motor drives the screw 7 to rotate, thereby driving the slide 6 to slide on the fixed seat 5, and then driving the printing assembly 2 to translate relative to the printing base plate 3.

[0036] In this embodiment, the stepper motor and the coupling are both located on the side of the mounting plate 52 .

[0037] The beneficial effect of this embodiment is that by providing a stepper motor, a coupling, etc., the printer can adjust the position of the printing assembly 2 according to the position to be printed on the label, which makes the adjustment more labor-saving and convenient, and improves the degree of automation.

[0038] Example 3

[0039] The difference between this embodiment and the first embodiment is that this printer further includes a sliding seat and a sliding force source connected to each other, the fixed seat 5 is fixed on the sliding seat, and the sliding force source can drive the sliding seat to move closer to or away from the mounting seat 1.

[0040] In this embodiment, the sliding seat is a plate structure located on the side of the mounting base 1. The sliding force source can be a pneumatic cylinder or an electric push rod. This sliding force source drives the sliding seat to move closer to or further from the mounting base 1, thereby adjusting the distance between the printing assembly 2 and the winding assembly, adapting to installation conditions of varying sizes and meeting different printing requirements.

[0041] The beneficial effect of this embodiment is that by setting a sliding seat and a sliding force source, the printer can adjust the distance between the printing component 2 and the winding component, can adapt to the needs of different working conditions, has stronger applicability, a wider range of applications, and is more convenient to use.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes, combinations, or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
