Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a label printing machine which is easy to adjust. Background Art

[0002] Labels are generally used to mark product targets and categories or contents. Most of the labels referred to in the printing industry are printed materials used to identify the relevant instructions of their own products, and most of them have glue on the back, but there are also some that are printed without glue, which can also be called labels. Labels with glue are commonly known as self-adhesive labels. In order to facilitate the subsequent sale or use of labels, some businesses generally use printing machines to print the required content on the labels.

[0003] When the existing adjustable label printing machine is working, the reeling mechanism therein continuously reels the printed labels and simultaneously draws the label paper out of the feeding mechanism. During this process, the reeling mechanism and the feeding mechanism exert tension on the label paper, making the label paper in a straightened state. When the label paper is completely drawn out of the feeding mechanism, the label paper at the tail end will not have tension and will be in a loose state, which may easily lead to printing deviations and make it difficult for the label at the tail end to meet the requirements. In view of this, we propose a label printing machine that is easy to adjust. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Example:

[0022] This embodiment discloses a label printing machine that is easy to adjust. Figures 1 to 4 , including a printing machine body 1 and a finishing mechanism 2.

[0023] like Figure 1 As shown, the printing machine body 1 includes an equipment frame 101, a feeding mechanism 102 is provided at one end of the equipment frame 101, a printing mechanism 103 is provided at the other end of the equipment frame 101, and a winding mechanism 104 is provided at the bottom of the printing mechanism 103. In this embodiment, the printing machine body 1 is an existing label printing device on the market, wherein the feeding mechanism 102 is used to place the label roll to be printed, the printing mechanism 103 is used to print the label, and the winding mechanism 104 is used to wind up the printed label.

[0024] like Figures 1 to 4 As shown, the sorting mechanism 2 is arranged between the feeding mechanism 102 and the printing mechanism 103 .

[0025] Specifically, Figure 1 As shown, the sorting mechanism 2 includes an L-shaped mounting plate 201 and a pressing plate 202. One side of the bottom of the L-shaped mounting plate 201 is fixedly connected to the middle surface of the equipment frame 101. The pressing plate 202 is arranged at the top of one end of the L-shaped mounting plate 201, and one end of the pressing plate 202 is movably connected to the side of the other end of the L-shaped mounting plate 201. A plurality of C-shaped mounting frames 203 are fixedly connected at equal intervals at the bottom of the pressing plate 202. A pressing roller 204 is arranged in the C-shaped mounting frame 203. The bottom surface of the pressing roller 204 is connected to the top surface of one end of the L-shaped mounting plate 201. The two ends of the pressing roller 204 are rotatably connected to the two ends of the bottom of the C-shaped mounting frame 203 through a rotating shaft. A guide rod 205 is fixedly connected to the top of one end of the L-shaped mounting plate 201. A through hole 2021 is opened in the pressing plate 202 relative to the guide rod 205. The side of the guide rod 205 is slidably connected to the inner wall of the through hole 221. 05 is provided with a spring 206, one end of the spring 206 is fixedly connected to the bottom surface of the pressure plate 202, and the other end of the spring 206 is fixedly connected to the top surface of one end of the L-shaped mounting plate 201. The pressure plate 202 is pulled upward to make the guide rod 205 slide in the through hole 2021 and stretch the spring 206 at the same time, so that the unprinted label paper passes through the gap between the pressure roller 204 and the top surface of one end of the L-shaped mounting plate 201, and the pressure plate 202 is released. The spring 206 is reset to drive the pressure roller 204 to press the label paper. During the printing process, the winding mechanism 104 will continuously wind up the printed labels and pull out the label paper of the feeding mechanism 102. During the movement of the label paper, it will drive the pressure roller 204 to rotate at the bottom of the C-shaped mounting frame 203, which can ensure that the label paper is always in a flat state and can also ensure the smooth movement of the label paper.

[0026] Further, such as Figure 2 , Figure 3 As shown, a T-shaped slider 2022 is provided at one end of the pressure plate 202, and a T-shaped groove 2011 is opened at a position of the L-shaped mounting plate 201 relative to the T-shaped slider 2022. One end of the pressure plate 202 slides with the side of the other end of the L-shaped mounting plate 201 through the T-shaped slider 2022 and the T-shaped groove 2011. When the guide rod 205 slides upward in the through hole 2021, it drives one end of the pressure plate 202 to slide with the side of the other end of the L-shaped mounting plate 201 through the T-shaped slider 2022 and the T-shaped groove 2011.

[0027] Further, if Figure 1 , Figure 2 As shown, the top surface of the other end of the L-shaped mounting plate 201 is rotatably connected to a push rod 207, and a push block 208 is fixedly connected to the top of the push rod 207. When label paper needs to be installed, the push rod 207 is rotated, and the push rod 207 drives the push block 208 to flip upward to lift the pressure plate 202.

[0028] It is worth noting that if Figure 2As shown, a clamping cavity 2012 is provided on the top surface of one end of the L-shaped mounting plate 201, and the bottom end of the push rod 207 extends into the clamping cavity 2012 and is rotatably connected to the cavity walls on both sides of the clamping cavity 2012 through a rotating shaft. When the push rod 207 is rotated, the bottom end of the push rod 207 flips over in the clamping cavity 2012.

[0029] It is worth noting that Figure 2 , Figure 4 As shown, both sides of the top block 208 are arc-shaped, which facilitates the side of the top block 208 to lift up the pressure plate 202. The top of the top block 208 is horizontal. When the top of the horizontal top block 208 contacts the bottom surface of the pressure plate 202, if there is no external force pulling the top rod 207, the pressure plate 202 will always be in a lifted state, so that workers do not need to keep pulling the pressure plate 202 when installing label paper.

[0030] Working principle: When the utility model is used, the push rod 207 is rotated upward by hand, and the bottom end of the push rod 207 is turned over in the clamping cavity 2012. The push rod 207 drives the top block 208 to turn upward, lifts the pressure plate 202, and drives the T-shaped slider 2022 at one end of the pressure plate 202 to slide within the T-shaped slide groove 2011. The guide rod 205 slides in the through hole 2021 and stretches the spring 206 at the same time, so that the unprinted label paper passes through the gap between the pressure roller 204 and the top surface of one end of the L-shaped mounting plate 201. The push rod 207 is rotated to drive the top block 208 to separate from the pressure plate 202. The spring 206 is pulled out of the pressure plate 202. 06 Reset drives the pressure roller 204 to press the label paper. During the printing process, the reeling mechanism 104 will continuously reel up the printed labels and pull out the label paper from the feeding mechanism 102. During the movement of the label paper, the pressure roller 204 will drive the rotation of the bottom of the C-shaped mounting frame 203. When the label paper on the feeding mechanism 102 is pulled out, there will be no tension between the reeling mechanism 104 and the reeling mechanism 104. At this time, the pressure roller 204 presses the remaining label paper on the L-shaped mounting plate 201 to ensure that the label paper is always in a flat state, thereby ensuring the printing of the printing mechanism 103.

[0031] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
