Description

Technical Field

[0001] This invention relates to the field of packaging label printing equipment technology, and in particular to a thermal transfer coding machine. Background Technology

[0002] Current thermal transfer coding machines suffer from several structural and functional deficiencies, making it difficult to meet the demands for efficient and stable printing. Specific problems include: Inadequate design of the mechanism adjustment and printhead pressing mechanism; the mechanism is often fixed or only slightly movable, resulting in poor adaptability to different printing areas; the printhead presses down directly vertically, causing significant friction with the ribbon and media, leading to short lifespan and high replacement costs. Ribbon transmission stability is insufficient, with only a single guide shaft, making it prone to deviation and wrinkling during high-speed printing, resulting in blurred markings; the recycling drive and transmission monitoring are disconnected, failing to adjust in time when the ribbon jams or slips, easily leading to breakage or ink waste. The ribbon supply and recycling module adjustment flexibility is low, often fixed, unable to adjust position according to ribbon tension and media thickness, resulting in poor fit, affecting print quality and easily causing ribbon failure. Reliance on air to drive mechanism movement and printhead pressing requires a dedicated air system, increasing deployment costs and footprint, making it unusable in scenarios without an air source, such as temporary production lines or outdoor operations, severely limiting flexibility. Summary of the Invention

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-4This invention provides a thermal transfer coding machine, including a housing assembly 100. A core component moving module 2 and a core rotation and pressing module 3 are disposed in the middle of the housing assembly 100. Multiple ribbon guide shaft assemblies 400 are disposed inside the housing assembly 100. A ribbon recycling drive module 1 is disposed inside the housing assembly 100. A thermal head quick-release module 5 is disposed below the core component moving module 2, and a ribbon rotation sensor 6 is disposed above the core component moving module 2. The core rotation and pressing module 3 is connected to the core component. The module component flipping linkage module 10 is provided. The movement module 2 is connected to the movement drive system 11. A ribbon supply module 7 and a ribbon recycling shaft 8 are also provided between the multiple movement modules 2. The outer shell assembly 100 is provided with a slanted guide rail assembly 12 for driving the ribbon supply module 7 and the ribbon recycling shaft 8 to move obliquely in opposite directions. The outer shell assembly 100 is provided with a synchronous adjustment assembly 13 for driving the ribbon supply module 7 and the ribbon recycling shaft 8 to adjust up and down synchronously.

[0018] First, the ribbon is installed in the ribbon supply module 7 inside the housing assembly 100, and after being guided by multiple ribbon guide shaft assemblies 400, it is fixed to the ribbon recycling shaft 8. When the equipment is started, the movement drive system 11 drives the movement module 2 of the movement assembly to adjust to the target printing position. The rotating pressing module 3 of the mechanism drives the rotating swing arm to press down, so that the thermal head quick-release module 5 below the moving module 2 of the mechanism component first contacts the ribbon, and then presses down until the ribbon is in contact with the printing media and the rubber roller. The ribbon recycling drive module 1 drives the ribbon recycling shaft 8 to rotate, pulling the ribbon for transmission, and the thermal print head heats up to complete the printing; During printing, the ribbon rotation sensor 6 above the moving module 2 of the mechanism component monitors the ribbon status. The inclined guide rail assembly 12 on the housing assembly 100 can drive the ribbon supply module 7 and the ribbon recycling shaft 8 to move up and down in opposite directions to adjust the tension. The synchronous adjustment assembly 13 can drive the two to adjust their height synchronously. When maintenance is required, the movement mechanism rotation and pressing module 3 is connected to the movement mechanism module assembly flipping linkage module 10, which can drive the movement mechanism to flip, making operation convenient.

[0019] The function of the inclined guide rail assembly 12 is to drive the ribbon supply module 7 and the ribbon recycling shaft 8 to move obliquely up and down in opposite directions through the left inclined guide groove 121, the right inclined guide groove 122 and the inclined slider 123, thereby adjusting the ribbon tension, adapting to ribbons of different materials and widths and compensating for tension changes caused by ribbon consumption during printing, and ensuring stable transmission.

[0020] The synchronous adjustment component 13, through the synchronous lifting component 131 and the lead screw drive component 132, drives the ribbon supply module 7 and the ribbon recycling shaft 8 to move up and down synchronously, adapting to printing media of different thicknesses, ensuring consistent pressure between the ribbon and the thermal head and the media, and maintaining the linear stability of the ribbon transmission path, thus achieving precise printing in conjunction with the machine mechanism; Overall structure and core functional logic: The outer shell component 100 provides an overall installation frame for the equipment. The machine mechanism component moving module 2 in the middle can achieve precise lateral movement under the drive of the machine mechanism module moving drive system 11, thereby driving the thermal head quick-release module 5 below to cover different printing areas and adapt to multiple packaging specifications; The machine mechanism rotation and pressing module 3 reduces frictional wear between the thermal head and the ribbon and printing media by rotating and flexibly pressing down instead of the traditional vertical hard pressing. At the same time, the machine mechanism module flipping linkage module 10 connected to it can drive the machine mechanism to flip, facilitating maintenance and operation.

[0021] Ribbon transport and monitoring logic: Multiple ribbon guide shaft assemblies 400 inside the housing assembly 100 limit the ribbon in multiple directions to avoid transport deviation; the ribbon recycling drive module 1 provides power for ribbon recycling, and together with the ribbon supply module 7 and the ribbon recycling shaft 8, they form a complete ribbon transport path; the ribbon rotation sensor 6 above the movement module 2 of the movement assembly monitors the ribbon rotation status in real time. When the ribbon experiences abnormalities such as jamming or slippage, it can provide timely feedback to adjust the transmission parameters and prevent ribbon breakage or ink waste.

[0022] Ribbon adjustment logic: The inclined guide rail assembly 12 can drive the ribbon supply module 7 and the ribbon recycling shaft 8 to move obliquely up and down in opposite directions. By changing the relative height difference between the two, the ribbon tension is adjusted to adapt to ribbons of different materials and widths, or to compensate for tension changes caused by ribbon consumption during printing. The synchronous adjustment assembly 13 drives the two to move up and down synchronously, adjusting the overall height of the ribbon according to the thickness of the printing medium, ensuring that the ribbon is in consistent pressure with the thermal head and the printing medium, and ensuring print clarity.

[0023] The housing assembly 100 of the present invention includes a main body 200, and a ribbon mounting mechanism 300 is provided on one side of the main body 200. The housing assembly 100 is composed of the main body 200 and the ribbon mounting mechanism 300, and the two have a clear division of labor: the main body 200 serves as the mounting carrier for the core functional modules, and is used to fix key components such as the movement module 2, the movement rotation and pressing module 3, and the ribbon recovery drive module 1, to ensure the stability of each module during operation; the ribbon mounting mechanism 300 is specifically used to install the ribbon supply module 7, the ribbon recovery shaft 8, and ribbon guiding components, forming an independent ribbon processing area, which facilitates ribbon loading and unloading and avoids interference between ribbon transmission and movement of the movement.

[0024] The ribbon guide shaft assembly 400 of the present invention includes four ribbon mounting module positioning shafts 4 disposed on the inner wall of the main body 200. The inner wall of the ribbon mounting mechanism 300 is provided with four ribbon direction limiting bushings 9 that can be respectively fitted into one of the corresponding ribbon mounting module positioning shafts 4. The ribbon guide shaft assembly 400 achieves precise ribbon guidance through the cooperation of "positioning shafts + limiting bushings": the four ribbon mounting module positioning shafts 4 on the inner wall of the main body 200 provide a fixed guiding reference for ribbon transmission and limit the basic transmission path of the ribbon; the four ribbon direction limiting bushings 9 on the inner wall of the ribbon mounting mechanism 300 are respectively fitted into the corresponding positioning shafts 4. The bushings can rotate slightly to reduce the frictional resistance during ribbon transmission, and at the same time further limit the lateral deviation of the ribbon, ensuring that the ribbon is always stably transmitted along the set path, avoiding ribbon wrinkles and blurry printing problems caused by insufficient guidance.

[0025] The ribbon supply module 7 and the ribbon recycling shaft 8 described in this invention are spaced apart on the left and right sides. The spaced arrangement of the ribbon supply module 7 and the ribbon recycling shaft 8 forms a lateral transmission path of "supplying ribbon on the left and recycling on the right". This layout allows the ribbon to pass naturally through the thermal head printing area below the movement module 2 of the mechanism component after being led out from the supply end, and then enter the recycling end, without the need for a complex turning structure. At the same time, the spaced design on the left and right sides provides installation space for components such as the ribbon guide shaft assembly 400 and the ribbon rotation sensor 6, ensuring that each component is arranged in an orderly manner on the ribbon transmission path without interfering with each other, thus ensuring the continuity and stability of the ribbon transmission.

[0026] The inclined guide rail assembly 12 of the present invention includes a left inclined guide groove 121 and a right inclined guide groove 122 disposed on the ribbon mounting mechanism 300. An inclined slider 123 is disposed in each of the left and right inclined guide grooves 121 and 122. The ribbon supply module 7 and the ribbon recycling shaft 8 are respectively mounted on one of the corresponding inclined sliders 123. The inclined guide rail assembly 12 achieves reverse inclined adjustment of the ribbon module through the structure of "inclined guide groove + slider": the left and right inclined guide grooves 121 and 122 on the ribbon mounting mechanism 300 provide a moving track for the inclined slider 123. The ribbon supply module 7 and the ribbon recycling shaft 8 are respectively fixed on the two inclined sliders 123. When an external force drives the inclined slider 123 to move along the inclined guide groove, the left slider drives the ribbon supply module 7 to rise or fall, and the right slider simultaneously drives the ribbon recycling shaft 8 to fall or rise. Through the opposite inclined movements of the two, the stretching degree of the ribbon is changed, thereby precisely adjusting the ribbon tension to adapt to different printing needs.

[0027] The left inclined guide groove 121 and the right inclined guide groove 122 of the present invention are symmetrically arranged in a V-shape. The core working principle of the left inclined guide groove 121 and the right inclined guide groove 122 being symmetrically arranged in a V-shape lies in "symmetrical adjustment + uniform tension": the V-shaped structure makes the inclination direction of the two inclined guide grooves opposite, ensuring that the oblique movement distance of the ribbon supply module 7 and the ribbon recycling shaft 8 is always symmetrical, avoiding ribbon tension imbalance caused by excessive adjustment on one side; the left and right symmetrical design ensures that the ribbon is always in the central area of ​​the equipment during the transmission process, and will not shift laterally due to module adjustment, further improving the stability of ribbon transmission and ensuring accurate printing position.

[0028] The synchronous adjustment component 13 of this invention includes a synchronous lifting component 131 and a lead screw drive component 132 disposed on the ribbon mounting mechanism 300. The synchronous lifting component 131 is connected to the two inclined sliders 123, and the lead screw drive component 132 is connected to the synchronous lifting component 131. The synchronous adjustment component 13 achieves synchronous height adjustment of the ribbon module through the synergistic effect of the "synchronous lifting component + lead screw drive component": the lead screw drive component 132 provides the power source for adjustment, driving the synchronous lifting component 131 to move; the synchronous lifting component 131 is connected to the two inclined sliders 123, which can convert the rotational motion of the lead screw into the synchronous up-and-down linear motion of the two inclined sliders 123; since the two inclined sliders 123 respectively drive the ribbon supply module 7 and the ribbon recycling shaft 8, the two can achieve synchronous height adjustment, changing the overall height of the ribbon to adapt to printing media of different thicknesses while maintaining the linear stability of the ribbon transmission path and avoiding tension fluctuations.

[0029] The synchronous lifting assembly 131 of this invention includes a vertical guide rail 1311 disposed on the carbon ribbon mounting mechanism 300. A movable crossbar 1312 is vertically movable within the vertical guide rail 1311. A transverse straight slot 1313 is provided on the movable crossbar 1312. A drive shaft 1314 is disposed on the back of the inclined slider 123. Two drive shafts 1314 are movably mounted within the transverse straight slot 1313. The synchronous lifting assembly 131 achieves this through a combination of vertical guide rail, movable crossbar, slot, and shaft. Synchronous transmission is achieved: the vertical guide rail 1311 limits the movement direction of the moving crossbar 1312, ensuring that it can only rise and fall smoothly in the vertical direction; the horizontal straight slot 1313 on the moving crossbar 1312 forms a sliding engagement with the drive shaft 1314 on the back of the inclined slider 123. When the moving crossbar 1312 rises and falls along the vertical guide rail 1311, the horizontal straight slot 1313 drives the two inclined sliders 123 to move synchronously through the drive shaft 1314. Since the slot is horizontally straight, it can accommodate the oblique displacement of the inclined sliders 123 in the oblique guide slot, thus achieving synchronous lifting and lowering without affecting the subsequent tension adjustment through the oblique guide rail assembly 12.

[0030] The lead screw drive assembly 132 of the present invention includes a vertical lead screw mounting seat 1321 disposed in the middle of the carbon ribbon mounting mechanism 300. A rotating lead screw 1322 is rotatably mounted in the vertical lead screw mounting seat 1321. A vertical threaded sleeve 1323 is disposed in the middle of the moving crossbar 1312. The rotating lead screw 1322 passes through the vertical threaded sleeve 1323 and is threadedly connected to the vertical threaded sleeve 1323.

[0031] The rotating lead screw 1322 of the present invention is provided with an adjustment part 1000 at its end.
