Abstract
Description
A strapping device with dot-matrix printing function Technical Field
[0001] This utility model relates to the field of strapping technology, and in particular to a strapping device with a needle-type printing function. Background Technology
[0002] Strapping equipment generally includes a housing, inside which is a reel on which strapping tape is wound as strapping tape. Strapping tape is supplied through the strapping mechanism in the housing via pressure rollers and / or guide rollers, and the strapping tape completes the strapping of the corresponding items.
[0003] In related technical solutions, after bundling items with straps, laser printing is required to mark product information on the straps. However, laser printing is costly and requires an additional laser printer. Furthermore, the positioning of the items and the straps relative to the laser printer varies depending on the shape and size of the bundled items. Summary of the Invention
[0004] This invention provides a strapping device with needle-type printing function, which can solve at least one of the above-mentioned technical problems.
[0005] To address the aforementioned technical problems, one or more embodiments of this utility model provide a strapping device with dot matrix printing functionality, comprising a housing containing a tape reel and a printing assembly. Strapping tape is wound on the tape reel, with one end of the strapping tape extending from the reel and passing through the printing assembly. The printing assembly includes a guide plate, a dot matrix printhead, a ribbon cassette, and a ribbon drive assembly. The guide plate has an internal cavity extending through itself to allow the strapping tape to pass through. The guide plate has a first opening and a second opening, arranged opposite to each other, extending through both side walls along its thickness direction. A guide wheel is installed at the first opening to abut against the strapping tape. The ribbon cassette stores ribbon, with a portion of the ribbon extending outside the cassette and positioned at the second opening. The portion of the ribbon outside the cassette is in contact with the strapping tape at the second opening, where the ribbon is positioned between the dot matrix printhead and the strapping tape. The ribbon drive assembly can drive the ribbon and the strapping tape to move synchronously at the second opening.
[0006] The beneficial effects of one or more of the above technical solutions are as follows:
[0007] In this solution, a printing component is installed inside the strapping device. This component can print the required information within the internal cavity of the strapping device while the strapping tape is being produced. Compared to laser printing after the items are strapped, this avoids printing problems caused by variations in the shape and size of the strapped items. Furthermore, the combination of the dot-matrix printhead and the ribbon in this setup effectively reduces the footprint of the printing component, making it easier to integrate the printing component into the casing of the strapping device.
[0008] In this solution, the printing assembly includes a guide plate, a dot matrix printhead, a ribbon cartridge, and a ribbon drive assembly. The guide plate has an inner cavity for the strapping to pass through, and it has a first opening and a second opening through its sidewall. A guide wheel is located at the first opening, and the ribbon and the dot matrix printhead for printing through the ribbon are attached to the second opening. This arrangement facilitates the use of the first opening, the second opening, the guide wheel, and the dot matrix printhead to ensure a tight fit between the strapping and the ribbon at the second opening, and also facilitates rapid printing of the strapping using the dot matrix printhead.

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0017] It should be noted that, in addition to the tape reel, printing assembly, pressure roller assembly, and feed roller assembly described below, the strapping equipment should also include a strapping mechanism for performing the binding of items with strapping tape. However, since this application only involves the conveying of strapping tape within the housing and the printing of some content on the side of the strapping tape, that is, the strapping tape output from the feed roller assembly is used for subsequent binding. This application does not improve how the subsequent strapping tape specifically binds the items; this can be set by those skilled in the art, and will not be elaborated here.
[0018] As shown in Figures 1-6, one or more embodiments of this utility model provide a strapping device with dot matrix printing function, including a housing, in which a tape reel 2 and a printing assembly are installed. Strapping tape 24 is wound on the tape reel 2, and one end of the strapping tape 24 extends from the tape reel 2 and passes through the printing assembly. The printing assembly includes a guide plate 19, a dot matrix print head 20, a ribbon cartridge 5, and a ribbon drive assembly 6. The guide plate 19 has an internal cavity that extends through itself to allow the strapping tape 24 to pass through. The guide plate 19 has a first opening and a second opening that extend through both side walls along its thickness direction and are arranged opposite to each other. A guide wheel 21 that abuts against the strapping tape 24 is installed at the first opening.
[0019] The ribbon cassette 5 stores ribbon 23. Part of the ribbon 23 is led to the outside of the ribbon cassette 5 and is located at the second opening. The ribbon 23 outside the ribbon cassette 5 is attached to the strapping 24 at the second opening. The ribbon 23 at the second opening is located between the dot matrix printhead 20 and the strapping 24. The ribbon drive assembly 6 can drive the ribbon 23 and the strapping 24 to move synchronously at the second opening position.
[0020] Specifically, the housing includes a top plate, a bottom plate, and side plates, which together form the inner cavity of the housing. A base plate 8 and a fixing plate 7 are also fixed within the inner cavity of the housing, wherein the base plate 8 is used to mount the tape reel 2, and the fixing plate 7 is used to mount the printing assembly.
[0021] Existing dot matrix printers include a dot matrix printhead 20 and a ribbon 23. The dot matrix printhead 20 squeezes the ribbon 23 to form corresponding information on the surface of the printed object. The specific material of the ribbon 23 and the specific structure of the dot matrix printhead 20 will not be described in detail in this embodiment; those skilled in the art can determine these details themselves.
[0022] Specifically, a rotating shaft 16 is rotatably installed inside the housing, and an inner disc 1 is fixed to the outside of the rotating shaft 16. The aforementioned belt disc 2 is fixedly sleeved on the inner disc 1.
[0023] In this embodiment, the first opening and the second opening are square openings, and the projections of the first opening and the second opening along the thickness direction of the guide plate 19 coincide. The inner cavity of the guide plate 19 is square.
[0024] Specifically, the inner cavity of the guide plate 19 extends through the two side walls of the guide plate 19 along its own length direction, thereby allowing the color strip 23 to pass through the guide plate 19 along its length direction.
[0025] In this embodiment, the ribbon cassette 5 is equipped with a feed roller (not shown in the figure) and a take-up roller (not shown in the figure). The ribbon 23 on the feed roller is led out of the ribbon cassette 5 near the second opening, then led back to the ribbon cassette 5 and wound around the take-up roller. The take-up roller is connected to the ribbon drive assembly 6.
[0026] Specifically, the axes of the feed roller and the take-up roller are parallel to each other, and their axes are parallel to the guide plate 19. Initially, the unused ribbon 23 is completely wound around the feed roller, with one end of the ribbon 23 leading out. This led-out end of the ribbon 23 can be guided to the outside of the ribbon cassette 5 via the guide roller or guide groove, and then returned to the ribbon cassette 5. The ribbon 23 returned to the ribbon cassette 5 is then wound onto the take-up roller. At this time, through the feeding of the feed roller and the take-up of the take-up roller, the ribbon 23 outside the ribbon cassette 5 continuously moves at the second opening position to move synchronously with the strapping 24.
[0027] When the second nozzle is used, the dot-matrix printhead 20 presses against the ribbon 23, and part of the ribbon 23 presses against the strapping 24. The other side of the strapping 24 is stopped and driven by a pulley. As a result, the ribbon 23 can leave the required information on the surface of the strapping 24 to complete the marking.
[0028] In this embodiment, the ribbon driving assembly 6 includes a drive motor, which is connected to the take-up pulley via a pulley assembly.
[0029] Specifically, a first pulley is mounted on the output shaft of the drive motor, and a second pulley is mounted on the shaft of the take-up pulley. The first and second pulleys are connected by a belt. Preferably, the belt here is a synchronous belt.
[0030] In this embodiment, a pressure roller assembly is also included, comprising a first pressure roller 12 and a second pressure roller 10, with a gap between them for the strap 24 to pass through. The first pressure roller 12 is rotatably connected to the housing, and the second pressure roller 10 is rotatably connected to the mounting plate 11. One end of the mounting plate 11 is rotatably connected to the housing via a rotating shaft 16. A torsion spring is provided on the rotating shaft 16 to drive the mounting plate 11 and the second pressure roller 10 to move towards the side closer to the first pressure roller 12.
[0031] In the initial stage, the mounting plate 11 and the second pressure roller 10 are pulled by hand to increase the gap between the first pressure roller 12 and the second pressure roller 10, so that the strap 24 can be manually passed through. After the strap 24 has passed through the first pressure roller 12 and the second pressure roller 10 of the pressure roller assembly, the mounting plate 11 is released. At this time, the torsion spring will drive the mounting plate 11 and the second pressure roller 10 to return to their original positions, and the strap 24 will be pressed between the first pressure roller 12 and the second pressure roller 10.
[0032] In this embodiment, a belt feeder assembly 3 is also included, which includes a first belt feeder and a second belt feeder, forming a belt feed gap through the strap 24. At least one of the two has rotational power, and at least one of the two is equipped with an encoder 4. The encoder 4 is connected to the controller signal, and the controller controls the translation of the ribbon 23 and the printing of the dot print head 20.
[0033] The encoder 4 here includes an encoder body 15 and a signal transmission component that transmits the signals measured by the encoder body 15 to the controller. An operation screen 18 is also provided on the exterior of the housing to input operation commands to the controller.
[0034] Specifically, the aforementioned rotational power is provided by a rotary motor 14, which means that either the first or second feed roller is fixed coaxially with the rotary motor.
[0035] In this embodiment, one of the first and second feed rollers is rotatably connected to the machine housing, and the other is rotatably connected to the rotating plate. The rotating plate is rotatably connected to the machine housing via a rotating shaft 9, on which a second torsion spring is mounted. Referring to the pressure roller assembly described above, manually bending the rotating plate here increases the distance between the first and second feed rollers, thereby facilitating the passage of the strapping 24 through the gap in the feed roller assembly 3 in the initial stage.
[0036] In this embodiment, a reel drive motor 13 is installed inside the housing to drive the reel 2 to rotate and release the strapping 24. In this embodiment, the strapping 24 is a paper tape; in other embodiments, it can be made of other materials.
[0037] Working principle: A reel 2 is fixedly sleeved on the inner disc 1. Strapping 24 extends from the reel 2, passing between the first and second pressure rollers. The reel 2 rotates, driven by the motor 14, pulling out excess strapping 24. The pulled-out strapping 24 passes through the guide plate 19 and then through the gap between the first and second feed rollers. The feed roller assembly 3 rotates, causing the strapping 24 to move forward, thereby driving the encoder 4 to collect the rotation signal of the feed roller assembly 3. The linear velocity of the feed roller assembly 3 is equal to the speed of the strapping 24. Therefore, the encoder 4 can indirectly measure the length of the strapping 24 extending out of the machine housing.
[0038] The encoder 4 collects the signal indicating the movement of the strapping tape 24 and sends it to the controller. The controller then transmits the information edited on the operation screen 18 to the dot matrix printhead 20. The dot matrix printhead 20 squeezes the ink ribbon 23, leaving information on the strapping tape 24. During the process of the dot matrix printhead 20 squeezing the ink ribbon 23, the ink ribbon 23 and the strapping tape 24 move synchronously, thus preventing the movement of the strapping tape 24 from affecting the printing action of the dot matrix printhead 20.
[0039] The specific embodiments described above should not be construed as limiting the scope of protection of this utility model. Any substitutions, improvements, or modifications made to the embodiments of this utility model by those skilled in the art will fall within the scope of protection of this utility model. Any aspects not detailed in this utility model are well-known to those skilled in the art.
