Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of positioning mechanisms for text printing, and in particular to a positioning mechanism for text printing. Background Technology
[0002] A printing press is a device used for printing text and images. It uses mechanical equipment to print graphic information onto media such as paper, cloth, plastic, and metal. Modern printing presses typically consist of mechanisms for plate mounting, inking, printing, and paper feeding. Their working principle is to create a printing plate from the text and images to be printed, and then transfer ink to the substrate through steps such as inking and printing, thereby reproducing a printed product identical to the printing plate.
[0003] The primary function of a printing press is to efficiently meet the needs of printing large volumes of text and images. Whether it's the intricate typesetting of books or the exquisite printing of posters and flyers, it can handle it with ease. It boasts superior batch processing capabilities, simultaneously printing on various media such as paper, cardstock, and art paper. It can print on large quantities of media at once, outputting complex color images, and can provide different printing styles and personalized services according to customer needs, such as engraving plates, hot stamping plates, and UV-cured plates. Modern printing presses also utilize computer-controlled technology, improving print quality and efficiency, making them suitable for office environments and commercial printing.
[0004] While the aforementioned technologies enable text printing and the output of complex color images, existing text printing paper positioning mechanisms suffer from severe limitations in practical applications. They often fall short when faced with different paper sizes. In terms of length, printing tasks involve a wide range of paper lengths, and existing positioning mechanisms are mostly designed for fixed lengths, lacking adjustment flexibility. Regarding width, the market offers a wide variety of paper widths, and existing positioning mechanisms with clamping and limiting components are only suitable for narrow widths, making it difficult to effectively constrain wide paper. This results in the paper not being stably centered in the printing area, easily shifting left and right, causing uneven distribution of printed content, affecting aesthetics and professionalism. Crucially, text printing paper varies in thickness, and existing positioning mechanism designs do not fully consider this, with clamping and support structures only applicable to specific thickness ranges. Therefore, a new text printing positioning mechanism is proposed to address these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a positioning mechanism for text printing, which aims to solve the problem that existing positioning mechanisms in the prior art cannot position text paper of different lengths, widths and thicknesses.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3 An embodiment of this utility model provides a positioning mechanism for text printing, including a printing machine 1. A base plate 2 is slidably connected inside the printing machine 1, and a platform 3 is slidably connected to the top of the base plate 2. The platform 3 provides support for the paper being printed. A left-right adjustment component 5 is provided at the bottom of the base plate 2. A first base 6 is fixedly connected to both ends of the top left side of the base plate 2. A second base 7 is fixedly connected to the middle of the top left side of the base plate 2. A third base 8 is fixedly connected to both ends of the top right side of the base plate 2. A front-back adjustment component 4 is provided at the top of the base plate 2.
[0033] The left-right adjustment component 5 includes a second bidirectional screw 51, a mechanical device for transmitting force and motion. It consists of two symmetrical helical toothed grooves, one internally threaded and the other externally threaded. When the two threads are axially opposite, the second bidirectional screw 51 has the ability to transmit motion and force. Its main function is to convert rotational motion into linear motion. A support block 52 is rotatably connected to the outer wall of the second bidirectional screw 51, and a slider 53 is threadedly connected to its outer wall. A crank handle 56 is fixedly connected to the front end of the second bidirectional screw 51. Manually rotating the crank handle 56 clockwise or counterclockwise rotates the second bidirectional screw 51, causing the slider 53 connected to the second bidirectional screw 51 to move inward or outward within the groove 46. The movement of the slider 53 causes the upright rod 55 connected to the slider 53 to move inward or outward, thus moving the pressure plate below the upright rod 55. The left and right adjustment component 5 includes a vertical rod 55, which has a groove 57 inside. The bottom of the vertical rod 55 is elastically connected to a fixing block 59 by a spring 58. The spring 58 and the fixing block 59 are also set inside the vertical rod 55, connecting the fixing block 59 to the pressure plate 54. When the paper for printing the text is thick, the elasticity of the spring 58 can lift the pressure plate 54 upward, thus fixing the text with different paper thicknesses. The bottom of the fixing block 59 is fixedly connected to the pressure plate 54.
[0034] Reference Figures 1-4The front and rear adjustment assembly 4 includes a motor 41. The output end of the motor 41 is fixedly connected to a first bidirectional screw 42. A first bracket 44 is threaded to the outer wall of the front end of the first bidirectional screw 42, and a second bracket 45 is threaded to the outer wall of the rear end of the first bidirectional screw 42. A slide rod 43 is slidably connected to the bottom right side of the first bracket 44. A groove 46 is provided on the top of the first bracket 44. When the motor 41 is turned on, the first bidirectional screw 42 rotates, causing the first bracket 44 and the second bracket 45 connected to the first bidirectional screw 42 to rotate inwards or outwards simultaneously. While the first bracket 44 and the second bracket 45 rotate, they move in the same direction as the first bidirectional screw 42 on the slide rod 43 fixed on the third base 8. This solves the problem of fixing text of different lengths during printing and prevents shaking during printing. The outer wall of the support block 53 is slidably connected to the inside of the channel rail 46. Both ends of the channel rail 46 are provided with sliders 53. The outer wall of the support block 52 is fixedly connected to the inside of the channel rail 46. The outer wall of the second bidirectional screw 51 is rotatably connected to the top of the first bracket 44. One end of the spring 58 is fixedly connected to the inside of the upright 55. The other end of the spring 58 is fixedly connected to the top of the fixing block 59. The spring 58 has a reset function on the pressure plate 54. The outer wall of the fixing block 59 is slidably connected to the inside of the groove 57. The top of the upright 55 is fixedly connected to the bottom of the slider 53. The right bottom of the second bracket 45 is slidably connected to the outer wall of the slide rod 43. The top of the second bracket 45 also has a screw with the same screw as the second bidirectional screw 51. The outer wall of the slide rod 43 is fixedly connected to the middle of the third base 8. The outer wall of the first bidirectional screw 42 is rotatably connected to the middle of the first base 6.
[0035] Working principle: During use, manually turn the crank 56 clockwise or counterclockwise to rotate the second bidirectional screw 51. This causes the slider 53, connected to the second bidirectional screw 51, to move inward or outward within the groove 46. The movement of the slider 53 causes the upright 55, connected to the slider 53, to move inward or outward, thus moving the pressure plate 54 below the upright 55 inward or outward. This solves the problem of fixing text of different widths during printing. Simultaneously, a spring 58 and a fixing block 59 are installed inside the upright 55, connecting the fixing block 59 and the pressure plate 54. When printing on thicker paper... The elasticity of spring 58 allows pressure plate 54 to be lifted upwards, thus fixing text of different paper thicknesses. Motor 41 is activated, driving the first bidirectional screw 42 to rotate. This causes the first bracket 44 and the second bracket 45, connected to the first bidirectional screw 42, to rotate inwards or outwards simultaneously. As the first bracket 44 and the second bracket 45 rotate, they move in the same direction as the first bidirectional screw 42 on the slide rod 43 fixed to the third base 8, thus fixing text of different lengths during printing and preventing shaking during printing.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
