[0002] Physical labels are simple signs used to indicate the name, weight, volume, purpose and other information of an item. Physical labels are widely used in the commodity field. They can not only provide commodity information, but also serve as a unique identifier for the commodity, thereby distinguishing it from other homogeneous commodities.

[0003] Since labels are widely used in the commodity field and are in great demand, assembly line-type high-speed marking devices are currently usually used to achieve rapid marking to meet the needs of large-scale label marking. However, during the high-speed marking process, the label marking quality also needs to be ensured.

[0004] However, the coordination accuracy between the laser marking machine and the label paper of the current marking equipment is not high enough, and the relative position between the two cannot be flexibly adjusted, which cannot meet the diverse high-precision marking needs.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 This application is described in further detail.

[0030] The embodiment of the present application discloses an efficient and high-precision laser marking device, which is mainly used for batch marking of labels before labeling. The marked labels can be rolled into label rolls and sent to the labeling device, or the marked label paper can be directly connected to the labeling device. Using this device to mark the label paper can effectively improve the efficiency and accuracy of marking.

[0031] A high-efficiency and high-precision laser marking device, refer to Figure 1 , including a frame 1, a marking table 2 for carrying label paper, a laser marking machine 3 for marking labels, and a feeding roller 4 and a receiving roller 5 located on both sides of the marking table 2. The marking head of the laser marking machine 3 is arranged toward the marking table 2. The label paper before marking is rolled up on the feeding roller 4. The feeding roller 4 rotates to release the label paper. The label paper passes through the marking table 2 and is rolled up by the receiving roller 5. The laser marking machine 3 points to the top of the marking table 2. As the receiving roller 5 rotates, the label paper passes through the marking table 2 in sequence, and is marked in sequence by the laser marking machine 3. The marking speed is fast and the precision is high.

[0032] Specifically, the feed roller 4, the receiving roller 5 and the marking table 2 are all installed on one side of the frame 1. For the convenience of expression, this side of the frame 1 is set as the mounting surface 101. The feed roller 4 and the receiving roller 5 are located at both ends of the mounting surface 101 along the length direction, and the marking table 2 is located in the middle and upper part of the mounting surface 101.

[0033] At the same time, two limit plates 10 are installed on the feed roller 4 and the receiving roller 5. The distance between the two limit plates 10 is slightly larger than the width of the label paper, so that the label paper can be smoothly released from the feed roller 4 and neatly rolled up onto the receiving roller 5. While improving the movement stability of the label paper, it can also make the label paper more neatly rolled up, making it easier for the subsequent labeling device to label the rolled label paper in sequence, thereby improving the operating efficiency of the entire work process.

[0034] In addition, a plurality of tensioning rollers 6 are provided on one side of the frame 1 located on the mounting surface 101. Tensioning rollers 6 are provided between the feed roller 4 and the marking platform 2 and between the receiving roller 5 and the marking platform 2. The label paper is released by the feed roller 4, and then tensioned by the tensioning roller 6 between the feed roller 4 and the marking platform 2 and passes through the marking platform 2. After the marking is completed on the marking platform 2, the label paper is tensioned by the tensioning roller 6 between the receiving roller 5 and the marking platform 2 and then reeled by the receiving roller 5. The tensioning roller 6 can keep the label paper in a taut state at all times, thereby ensuring that the label paper remains flat on the marking platform 2, improving the accuracy and quality of marking, and at the same time, the taut label paper is also convenient for the receiving roller 5 to reel, improving the reeling efficiency of the label paper and avoiding wrinkles in the reeling process.

[0035] Furthermore, limiting rollers 7 are provided at both ends of the marking table 2 along the moving direction of the label paper, and two limiting cylinders 8 are sleeved and fastened on each limiting roller 7, and a gap is left between the two limiting cylinders 8 for the label paper to pass through. The label paper moves stably on the marking table 2 under the limiting action of the side walls of the limiting cylinders 8, which makes it easier for the laser marking machine 3 to mark, thereby improving the marking accuracy and quality of the laser marking machine 3.

[0036] Furthermore, the frame 1 is provided with an adjustment bracket 9 for installing the laser marking machine 3. The adjustment bracket 9 can be used to adjust the position and angle of the laser marking machine 3 so that the laser marking machine 3 can accurately point to the label to be marked, ensuring that the laser marking machine 3 can achieve accurate marking.

[0037] Specifically, the adjustment bracket 9 includes a vertical support rod 91, a transverse support rod 92 and an adjustment block 93. The vertical support rod 91 is vertically installed on the frame 1, and the adjustment block 93 is slidably mounted on the vertical support rod 91 in the vertical direction and fixed by bolts. At the same time, one end of the transverse support rod 92 is horizontally penetrated on the adjustment block 93, and the other end is equipped with a laser marking machine 3. The transverse support rod 92 can slide in the horizontal direction in the adjustment block 93, and the transverse support rod 92 and the adjustment block 93 are also fixed by bolts.

[0038] During specific use, by loosening the fixing bolts between the vertical support rod 91 and the adjustment block 93, the adjustment block 93 can be moved up and down in the vertical direction on the vertical support rod 91, thereby driving the laser marking machine 3 to move accordingly; by loosening the fixing bolts between the transverse support rod 92 and the adjustment block 93, the transverse adjustment rod can be slid in the adjustment block 93, thereby driving the laser marking machine 3 to move closer to or away from the label paper in the horizontal direction.

[0039] Furthermore, one end of the housing of the laser marking machine 3 is hinged to one end of the transverse support rod 92 away from the adjustment block 93, and the axis of the hinge shaft is parallel to the moving direction of the label paper. The laser marking machine 3 can be rotated along the hinge shaft to adjust the angle between the laser marking machine 3 and the marking platform 2. According to the actual marking needs, the direction of the laser marking machine 3 is changed so that the laser marking machine 3 can point to the label paper more accurately.

[0040] The implementation principle of an efficient and high-precision laser marking device disclosed in an embodiment of the present application is as follows: before marking, adjust the distance and angle between the laser marking machine 3 and the marking table 2, then install the entire roll of label paper on the feed roller 4, and pull the label paper out, pass through the tensioning roller 6 and the marking table 2 in turn, and finally roll it up on the receiving roller 5, then adjust the laser marking machine 3 to align with the label paper on the marking table 2, drive the receiving roller 5 to rotate, drive the label paper to move, and mark it in turn.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
