Description

Technical Field

[0001] This utility model relates to the field of label printing machine technology, specifically to a label printing machine that is easy to adjust. Background Technology

[0002] Labels generally refer to products used to mark their target and classification or content. In the printing industry, labels are mostly printed materials used to identify relevant instructions for their products, and most of them have adhesive backing. However, some labels are printed without adhesive backing and can also be called labels. Labels with adhesive backing are commonly known as self-adhesive labels. In order to facilitate the subsequent sale or use of labels, some merchants will use printing presses to print the required content onto the labels.

[0003] In existing technologies, such as the Chinese patent publication number CN220280885U, "An Adjustable Label Printing Machine," a guide slide rod is used to allow the connecting plate to adjust the height of the fixed plate when the operator rotates the threaded adjustment rod inside the fixed bracket. This achieves rapid adjustment of the distance between the printing roller and the worktable, thus avoiding the need for operators to spend a long time adjusting the height when printing labels of different thicknesses, which would interfere with the operator's processing efficiency. At the same time, the cooperation between the guide slide rod and the guide sleeve makes the height adjustment of the printing roller more stable.

[0004] In the aforementioned prior art, although the height of the printing roller can be adjusted by rotating the threaded adjusting rod, enabling printing operations on labels of different thicknesses, the rigid contact between the printing roller and the label product may damage the label product, thereby reducing the printing quality of the label product.

[0021] Please see Figures 1 to 4 An easily adjustable label printing machine includes a mounting frame 2 fixedly mounted on the top of a mounting base 1. A support frame 5 is fixedly mounted on the top of the mounting base 1. The support frame 5 is fixedly mounted to the mounting frame 2. A support roller 9 is rotatably mounted between the support frame 5 and the mounting frame 2. An adjustment assembly is provided on the inner side of the support frame 5. The adjustment assembly includes a support plate 10 movably mounted on the inner side of the support frame 5. A threaded rod 16 is fixedly mounted on the top of the support plate 10. Two movable columns 18 are movably sleeved on the inner side of the support plate 10. Movable blocks 6 are fixedly mounted on the bottom ends of the movable columns 18. A printing roller 8 is rotatably mounted between the two movable blocks 6. A spring 19 is sleeved on the outer side of the movable columns 18.

[0022] In this embodiment: the vertical movement of the threaded rod 16 within the second pulley 15 allows the support plate 10 to be adjusted in height, thereby adjusting the height of the printing roller 8 and enabling printing operations on labels of different thicknesses. The elastic connection between the support plate 10 and the movable block 6 via the spring 19 allows for flexible contact between the printing roller 8 and the label product, avoiding damage caused by hard contact during printing and improving the printing quality of the label product.

[0023] As a technical optimization of this utility model, a feeding roller 3 for feeding material is provided on the front side of the mounting frame 2, and a receiving roller 4 for receiving material is provided on the front side of the mounting frame 2.

[0024] In this embodiment, by setting up a feeding roller 3 and a receiving roller 4, the label products fed out by the feeding roller 3 can be collected by the receiving roller 4 to complete the label product printing process.

[0025] As a technical optimization of this utility model, a fixing block 11 is fixedly installed on one side of the support frame 5, a rotating rod 12 is rotatably installed on the inner side of the fixing block 11, a first pulley 13 is fixedly installed at the top of the rotating rod 12, and a transmission belt 14 is driven to the outer side of the first pulley 13; a second pulley 15 is rotatably frictionally sleeved on the inner side of the support frame 5, the second pulley 15 is threadedly sleeved with the threaded rod 16, and the first pulley 13 is connected to the second pulley 15 through the transmission belt 14.

[0026] In this embodiment: by setting up a rotating rod 12, a transmission belt 14, and a second pulley 15, rotating the corresponding rotating rod 12 can drive the first pulley 13 to rotate. The first pulley 13 drives the transmission belt 14 and the second pulley 15 to rotate. The rotation of the second pulley 15 can drive the threaded rod 16, which is threadedly connected to the inner side of the second pulley 15, to move vertically. This allows the threaded rod 16 to drive the support plate 10 to make better height adjustments. The spring 19 at the bottom of the support plate 10 can drive the printing roller 8 on one side of the movable block 6 to make height adjustments, thus enabling printing operations on labels of different thicknesses.

[0027] As a technical optimization of this utility model, the top end of the spring 19 is fixedly connected to the support plate 10, the bottom end of the spring 19 is fixedly connected to the top of the movable block 6, and a damping block matching the spring 19 is provided on the inner side of the support plate 10.

[0028] In this embodiment, the support plate 10 and the movable block 6 are elastically connected by the spring 19. When the printing roller 8 on one side of the movable block 6 is in flexible contact with the label product, the damping effect of the damping block installed on the inner side of the support plate 10 on the spring 19 enables the printing roller 8 to make better contact with the label product, which facilitates the printing operation and avoids damage to the label product caused by hard contact.

[0029] As a technical optimization of this utility model, the top of the movable block 6 is fixedly installed with the printing machine body 7, the printing machine body 7 is installed in rolling contact with the printing roller 8, and the printing roller 8 is positioned corresponding to the support roller 9; the inner side of the support frame 5 is provided with a sliding groove 17, the movable block 6 is slidably installed with the support frame 5 through the sliding groove 17, and the support plate 10 is slidably installed with the support frame 5 through the sliding groove 17.

[0030] In this embodiment: by setting the slide groove 17, it is convenient for the support plate 10 and the support frame 5 to be slidably connected and installed, and the movable block 6 to be slidably connected and installed with the support frame 5, so that the printing roller 8 can better perform contact printing operations on label products of different thicknesses.

[0031] Working principle: During use, when adjusting the height of the printing roller 8, rotating the corresponding rotating rod 12 drives the first pulley 13 to rotate. At this time, the first pulley 13 drives the transmission belt 14 and the second pulley 15 to rotate. Then, the rotation of the second pulley 15 within the support frame 5 drives the threaded rod 16, which is threaded to the inner side of the second pulley 15, to move vertically. This allows the threaded rod 16 to drive the support plate 10 to make better height adjustments. The spring 19 at the bottom of the support plate 10 can drive the printing roller 8 on one side of the movable block 6 to make height adjustments, enabling printing operations on labels of different thicknesses. The damping block installed inside the support plate 10 dampens the spring 19, allowing the printing roller 8 to make better flexible contact with the label product, avoiding damage caused by hard contact during the printing process, and improving the printing quality of the label product.
