Description

Technical Field

[0001] This utility model relates to the field of printing machines, specifically to a printing machine for printing on the surface of rotating objects. Background Technology

[0002] A simple drag-and-drop printing press is a manual, portable printing device that imprints text or patterns onto the surface of an object by dragging it. Suitable for outdoor or temporary marking scenarios (such as logistics labels, warehouse management, document numbering, and printing beakers in the laboratory), its simple structure, lack of electricity, extremely low cost, and lightweight design greatly enhance its convenience. However, traditional simple drag-and-drop printing presses are ineffective on rotating surfaces because rotating objects are difficult to position, often resulting in low print quality. A search revealed no printing device capable of precisely positioning rotating objects and achieving rapid printing, nor is such a device readily available on the market. Therefore, it is necessary to develop a printing device capable of precise and rapid printing on the surface of rotating objects. Utility Model Content

[0003] This invention provides a printing machine for printing on the surface of rotating objects, which overcomes the problem of low printing quality on rotating surfaces in the prior art.

[0004] The technical solution of this utility model is as follows:

[0005] A printing machine for printing on the surface of rotating objects includes a frame supporting a rotating device and a product fixing device. The rotating device connects a roller printing device and a squeegee device. The product fixing device includes an adjusting plate, multiple rollers on the adjusting plate, and a first product positioning post and a second product positioning post on both sides of the adjusting plate. The roller printing device includes a roller printing shaft, a pattern fixing frame connected to the end of the roller printing shaft, and a roller printing pattern fixed by the pattern fixing frame. The roller printing device is slidably connected to the rotating device. The squeegee device includes a squeegee support frame and a squeegee connected to the end of the squeegee support frame. The squeegee support frame is hinged to the rotating device, and the squeegee device can rotate up and down.

[0006] This invention utilizes a drag lever mechanism comprised of a rotating device, a roller printing device, and a squeegee device to achieve printing with a single drag. The product fixing device allows printing on surfaces of rotating bodies of different sizes. Specifically, by adjusting the positions of the first product positioning post, the second product positioning post, and the rollers on the adjusting plate, precise positioning and fixing of rotating bodies of different sizes can be achieved. The rotating device connects the roller printing device and the squeegee device, enabling the overall vertical rotation of both devices; the sliding connection between the roller printing device and the rotating device allows for inward and outward dragging of the roller printing device; and the squeegee support frame of the squeegee device, hinged to the rotating device, allows for independent vertical rotation of the squeegee device.

[0007] Preferably, in the aforementioned printing machine for printing on the surface of rotating objects, the frame includes a base and a rotating frame, with the rotating frame mounted on the base. The frame is mounted on a base. This right-angled frame structure makes the equipment more robust and reliable during use.

[0008] Preferably, in the aforementioned printing machine for printing on the surface of rotating objects, the rotating frame is provided with a slide rail hole and a fixed hole, which are connected; the rotating frame is connected to a rotating device. The rotating device is installed in the fixed hole, and when the height of the rotating device needs to be adjusted, the rotating device can move up and down along the slide rail hole until it moves into the target fixed hole. This design is simple and facilitates the vertical adjustment of the rotating device.

[0009] Preferably, in the aforementioned printing machine for printing on the surface of rotating objects, the rotating device includes a rotating shaft placed in a fixed hole. A support plate is provided on the upper part of the rotating shaft. The support plate includes a base plate and a vertical plate. A slide rail is provided on the base plate and connected to the printing roller shaft. The top of the vertical plate is hinged to a squeegee support frame. Specifically, the rotating shaft allows the printing roller device and the squeegee device to rotate up and down as a whole, facilitating the installation and removal of the rotating object. The sliding connection between the slide rail and the printing roller shaft allows the printing roller device to be pulled inward and outward. The hinged connection between the top of the vertical plate and the squeegee support frame allows the squeegee support frame and the squeegee to rotate up and down independently.

[0010] Preferably, in the aforementioned printing machine for printing on the surface of rotating objects, the roller is mounted on a hole in the adjusting plate via a roller mounting base. This structural design facilitates the rotation of the roller.

[0011] Preferably, in the aforementioned printing machine for printing on the surface of rotating objects, the number of rollers is 4-8. This number of rollers is designed to accommodate printing on most rotating surfaces.

[0012] Preferably, in the aforementioned printing machine for printing on the surface of rotating objects, the adjusting plate has multiple holes. These multiple holes are used for adjusting the positions of the rollers, the first product positioning post, and the second product positioning post. This multi-hole design facilitates the adjustment of the roller position and the positions of the first and second product positioning posts, adapting to the positioning and fixing of rotating objects of different sizes.

[0013] The technical advantages of this invention are as follows: The dragging lever mechanism, composed of a rotating device, a roller printing device, and a squeegee device, enables printing to be completed with a single drag. The product fixing device allows for printing on rotating surfaces of different sizes. By installing different roller printing plates, diverse printing needs can be quickly met. This device is simple and convenient to operate, and boasts high printing efficiency. Attached Figure Description

[0020] A printing machine for printing on the surface of rotating objects includes a base 1 and a frame 2, wherein the frame 2 is fixed on the base 1.

[0021] The frame 2 includes a base 21 and a rotating shaft support frame 22, the rotating shaft support frame 22 being fixed to the base 21. The rotating shaft support frame 22 includes two side plates, each with symmetrically positioned openings, including slide rail holes 221 and multiple fixing holes 222. The rotating shaft support frame 22 is used to support the rotating device 3.

[0022] The rotating device 3 includes a rotating shaft 31, on which two rotating shaft positioning blocks 32 are fixedly mounted. A support plate 33 is provided on the upper part of the rotating shaft positioning blocks 32. The support plate 33 includes a base plate 331 and a vertical plate 332. A slide rail 34 is provided on the base plate 331, and a scraper device 5 is fixed to the upper end of the vertical plate 332. When the printing machine is in normal use, the rotating shaft 31 is hung on the fixed hole 222. When it is necessary to adjust the height of the rotating shaft 31, the rotating shaft 31 can slide up and down along the slide rail hole 221 to adjust to the target fixed hole 222.

[0023] The printing device 4 includes a printing shaft 41, which cooperates with a slide rail 34 and can slide within the slide rail 34. The printing shaft 41 passes through a through hole in the vertical plate 332 and can move freely within the through hole. A pattern fixing frame 42 is provided at the end of the printing shaft 41, which is used to fix the printing pattern 43, on which words or patterns for printing are provided.

[0024] The scraper device 5 includes a scraper 51 and a scraper support frame 52 for supporting the scraper 51. The scraper support frame 52 is connected to the upper end of the vertical plate 332 via a hinge. The scraper support frame 52 is a telescopic structure with an adjustable length.

[0025] A product fixing device 6 is provided on the base 21, and the product fixing device 6 is located below the printing plate 43. The product fixing device 6 includes an adjusting plate 65, which has multiple holes. The product fixing device 6 also includes multiple rollers 61, and in this embodiment, there are four rollers 61. The design of the rollers 61 allows the rotating object 7 to easily rotate to different surfaces for printing. The rollers 61 are fixed on roller fixing seats 62 and are mounted on the holes of the adjusting plate 65 through the roller fixing seats 62. The position of the rollers 61 can be adjusted by adjusting the position of the roller fixing seats 62 on the adjusting plate 65. A first product positioning post 63 and a second product positioning post 64 are respectively provided on both sides of the adjusting plate 65. The first product positioning post 63 and the second product positioning post 64 are mounted on the holes of the adjusting plate 65. The rotating object 7 to be printed (e.g., a beaker) is placed on the rollers 61 and precisely positioned by the first product positioning post 63 and the second product positioning post 64.

[0026] The usage process of this utility model is as follows: The rotating object 7, containing the text to be printed, is placed on multiple rollers 61 and supported by the rollers 61. The first product positioning post 63 and the second product positioning post 64 on both sides are adjusted to precisely fix and position the rotating object 7, ensuring accurate printing position. The printing plate 43 to be used is installed on the plate fixing frame 42. The height of the rotating shaft 31 is adjusted, and the printing plate 43 is rotated so that the lower end surface of the printing plate 43 abuts against the surface of the rotating object 7, applying a certain pressure to the rotating object 7. Ink is placed on the upper end surface of the printing plate 43, outside the "printed text". The squeegee 51 is held and pressed down, with the tip of the squeegee 51 abutting against the upper end surface of the printing plate 43, applying a certain pressure to the printing plate 43. The printing plate 43 is moved so that the squeegee 51 scrapes across the "printed text". During the process of moving the printing plate 43, the printing plate 43 drives the rotating object 7 to rotate. Under sufficient pressure, the printing plate 43 with the "printed text" makes full contact with the surface of the rotating object 7, thereby transferring the "printed text" onto the product surface. The drag lever structure design of this utility model can convert the horizontal or oblique pulling force applied by the operator into the vertical downward pressure of the scraper 51, and printing can be completed with a simple drag.

[0027] The foregoing general description of the utility model and its specific embodiments should not be construed as limiting the technical solution of the utility model. Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this utility model.
