Description

Technical Field

[0001] This utility model relates to the field of printer accessories technology, specifically to a printer ribbon cartridge with adjustment function. Background Technology

[0002] From the earliest mechanical impact printers to later computer dot matrix printers, ribbons have always been used as printing consumables. During the printing process, the ribbon, a strip-like material, is usually covered with ink or an ink coating to transfer ink and produce images, text, barcodes, etc., on the printing medium.

[0003] Existing devices primarily use gear structures to feed and tighten ink ribbons. Many existing technologies resemble printer ribbons with adjustable functions. For example, the structure in CN221067584U includes a mounting box with two symmetrically arranged rotating shafts rotatably connected inside. A drive gear is fixedly connected to the outer wall of each rotating shaft. An adjusting assembly is located inside the mounting box, including two movable plates that pass through and are rotatably connected to the side wall of the mounting box. These movable plates are fixedly connected by a connecting plate. This adjustable printer ribbon can adjust the tension of the ribbon, preventing it from gradually weakening and becoming loose. However, there are still areas for improvement in this device.

[0004] Existing devices primarily use cartridges of fixed lengths, making it difficult to adjust the guide wheel spacing according to the printer model, thus hindering the adjustment of the external ribbon length. Furthermore, some devices struggle to stably feed the ribbon, leading to excessive tightening force and ribbon breakage, reducing the device's efficiency and usability. Therefore, to address these issues, a ribbon cartridge with adjustable functionality for printers is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a ribbon cartridge with an adjustable function for printers, to solve the problem mentioned in the background art that existing devices mainly use cartridges of fixed length, making it difficult for some devices to adjust the spacing of the guide wheels according to the printer model, thus making it inconvenient to adjust the length of the external ribbon. At the same time, some devices have difficulty in stably feeding the ribbon, resulting in excessive tightening force and ribbon breakage in some devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a printer ribbon cartridge with an adjustable function, comprising a cartridge body, an adjustment box fixedly connected to the front center of the cartridge body, sliding frames provided on both sides of the front of the adjustment box, guide wheels fixedly connected to the ends of the sliding frames, a ribbon strip provided inside the cartridge body, the inner wall of the ribbon strip adhering to the outer wall of the guide wheel, and a control console fixedly connected to the top center of the cartridge body;

[0007] The adjustment box is equipped with an adjustment mechanism inside. The adjustment mechanism includes symmetrical screws, the two ends of which are movably connected to the two sides of the inner wall of the adjustment box. The two sides of the box are equipped with anti-loosening mechanisms, which include servo motors. The bottom of the servo motors is fixedly connected to the top left side of the box.

[0008] Preferably, a second bevel gear is fixedly connected to the middle of the outer wall of the symmetrical screw, and adjusting screw sleeves are meshed on both sides of the outer wall of the symmetrical screw. The front side of the outer wall of the adjusting screw sleeve passes through the adjusting box and is fixedly connected to the rear side of the sliding frame.

[0009] Preferably, a first bevel gear is meshed with the upper part of the second bevel gear, a drive shaft is fixedly connected to the middle of the top of the first bevel gear, and the top end of the drive shaft passes through the adjustment box and is fixedly connected to a twist cover.

[0010] Preferably, a drive shaft is fixedly connected to the bottom center of the servo motor, and the bottom end of the drive shaft passes through the housing and is fixedly connected to a drive gear.

[0011] Preferably, the drive gear is meshed with a driven gear on its rear side, and the colored strip passes through the meshing point of the drive gear and the driven gear.

[0012] Preferably, a telescopic cylinder is fixedly connected to the rear left side of the inner wall of the box, a buffer wheel is fixedly connected to the front end of the telescopic cylinder, a spring is fixedly connected to the rear side of the buffer wheel on the outer ring of the telescopic cylinder, and the rear end of the spring is fixedly connected to the inner wall of the box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the symmetrical screw, second bevel gear, adjusting screw sleeve, first bevel gear, transmission shaft, and twist cover in the adjusting mechanism, drives the transmission shaft and first bevel gear to rotate in a limited position by rotating the twist cover. The first bevel gear meshes and drives the second bevel gear and symmetrical screw to rotate in a limited position. The symmetrical screw drives the adjusting screw sleeve, sliding frame, and guide wheel to slide symmetrically, thereby realizing the adjustment of the guide wheel spacing. This allows some devices to adjust the guide wheel spacing according to the printer model, facilitating the adjustment of the length of the external color strip and improving the adjustability and practicality of the device.

[0015] 2. This utility model utilizes a servo motor, drive shaft, drive gear, driven gear, telescopic cylinder, buffer wheel, and spring in its anti-loosening mechanism. The servo motor, activated by a control console, drives the drive shaft and drive gear to rotate in a limited position. The drive gear meshes with the driven gear to transport the ribbon. Simultaneously, the ribbon slides backward via the traction buffer wheel, causing the buffer wheel to retract, the telescopic cylinder to compress the spring, and thus buffering the tension. This achieves anti-loosening of the ribbon, enabling stable transport of the ribbon in some parts of the device. It effectively prevents the ribbon from breaking due to excessive tightening force, improving the stability and practicality of the device. Attached Figure Description

The two ends of the symmetrical screw 21 are movably connected to the two sides of the inner wall of the regulating box 12. A second bevel gear 22 is fixedly connected to the middle of the outer wall of the symmetrical screw 21. Adjusting screw sleeves 23 are meshed on both sides of the outer wall of the symmetrical screw 21. The front side of the outer wall of the adjusting screw sleeve 23 passes through the regulating box 12 and is fixedly connected to the rear side of the sliding frame 13. Through this design, the second bevel gear 22 drives the symmetrical screw 21 to rotate in a limited position, so that the adjusting screw sleeve 23 drives the sliding frame 13 and the guide wheel 14 to slide symmetrically. A first bevel gear 24 is meshed above the second bevel gear 22. A transmission shaft 25 is fixedly connected to the middle of the top of the first bevel gear 24. The top of the transmission shaft 25 passes through the regulating box 12 and is fixedly connected to a twist cap 26.

[0025] The inner sides of the housing 11 are provided with anti-loosening mechanisms 3. The anti-loosening mechanism 3 includes a servo motor 31. The bottom of the servo motor 31 is fixedly connected to the top left side of the housing 11. The bottom middle of the servo motor 31 is fixedly connected to a drive shaft 32. The bottom end of the drive shaft 32 passes through the housing 11 and is fixedly connected to a drive gear 33. Through this design, the servo motor 31 drives the drive shaft 32 and the drive gear 33 to rotate in a limited position. The rear side of the drive gear 33 is meshed with a driven gear 34.

[0026] Working principle: When it is necessary to adjust the spacing of the guide wheels 14, firstly, by rotating the knob cover 26, the knob cover 26 drives the transmission shaft 25 to rotate in a limited position. The transmission shaft 25 drives the first bevel gear 24 to rotate synchronously. The first bevel gear 24 meshes with and drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the symmetrical screw 21 to rotate in a limited position. The symmetrical screw 21 drives the adjusting screw sleeve 23 to slide symmetrically. The adjusting screw sleeve 23 drives the sliding frame 13 and the guide wheels 14 to slide symmetrically, thus realizing the adjustment operation of the spacing of the guide wheels 14.

[0027] When it is necessary to prevent the ribbon strip 15 from loosening, the servo motor 31 is first started through the control console 16. The servo motor 31 drives the drive shaft 32 to rotate to the limit. The drive shaft 32 drives the drive gear 33 to rotate. The drive gear 33 meshes with the driven gear 34 to rotate, so that the drive gear 33 cooperates with the driven gear 34 to transport the ribbon strip 15. At the same time, the ribbon strip 15 can slide backward through the traction buffer wheel 36, so that the buffer wheel 36 retracts the telescopic cylinder 35 and compresses the spring 37 to buffer the tension, thus realizing the anti-loosening operation of the ribbon strip 15. The operation ends here.
