For this purpose, as shown in fig. 1, the laser engraving machine according to the present utility model includes a table 100, a positioning unit 200, a conveying unit, a tensioning unit and a control unit 500, wherein the positioning unit 200 is mounted on the table 100, the conveying unit is disposed below an end surface of the table 100, so that the elastic belt 600 is better pressed against the table 100, and the control unit 500 is used for controlling the positioning unit 200, the conveying unit and the tensioning unit. Specifically, the positioning unit 200 is used for positioning the strip-shaped elastic belt 600, and the laser engraving head 110 is installed above the workbench 100, and the laser engraving head 110 is used for performing laser engraving processing on the elastic belt 600. Specifically, the conveying unit includes a first belt feeding unit 310 and a second belt feeding unit 320, the first belt feeding unit 310 and the second belt feeding unit 320 are respectively located at both sides of the table 100, and the elastic belt 600 sequentially passes through the first belt feeding unit 310, the positioning unit 200, and the second belt feeding unit 320. Further, the tensioning unit comprises a first tape assembly 410 and a second tape assembly 420, the first tape assembly 410 being located on a side of the first tape assembly 310 facing away from the table 100, the second tape assembly 420 being located on a side of the second tape assembly 320 facing away from the table 100, the first tape assembly 410 and the second tape assembly 420 being each adapted to drive the elasticity to be moved along the side facing away from the table 100. It should be noted that, the elastic belt 600 is positioned on the workbench 100 through the positioning unit 200, and is tensioned by the tensioning unit, and is conveyed by the conveying unit in a stepping manner, so that the continuous laser engraving treatment is realized on the elastic belt 600 by using the laser engraving head 110, the operation is convenient, the flexibility of the engraved pattern is higher, and the quality of the engraved product is better.

In the application, the effect of the braid which is required to be more refined in pattern cannot be achieved through the modes of pattern weaving or word pressing processing and the like. However, the laser engraving process of this embodiment can achieve, it needs to be explained that the laser engraving machine processes through software drawing and then outputs through engraving software and beats the surface of the fabric, the figure can be adjusted in real time according to the engraving effect, the mould does not need to be customized, time and cost of the mould are saved greatly, and the requirement on the material of the fabric itself is not high, almost any material can achieve the engraving effect and pass the water washing test, because the engraving only adopts the laser with high energy density to burn out the material with very few surface of the fabric, the whole appearance influence on the fabric is less, therefore it is more suitable for the product that we do some high quality requirements.

In addition, since the conventional engraving machine can only fix the material first and then engrave, and since the elastic band 600 has elasticity, too much manual intervention cannot ensure consistency of positioning and stretching of the material, and quality of the finished product needs to be engraved in continuous conveyance for the elastic band 600. In some embodiments, the elastic band 600 adopts a continuous engraving mode, that is, the elastic band 600 is laser engraved by the laser engraving head 110 under continuous conveyance of the conveying unit, and the elastic band 600 is not stopped on the table 100. Correspondingly, the laser engraving head 110 continuously operates, and after engraving, the surface of the whole elastic band 600 has patterns. In some embodiments of the present utility model, the elastic band 600 adopts a discontinuous carving mode, as shown in fig. 1, the positioning unit 200 includes a camera 120, the elastic band 600 is provided with an identification pattern for visual identification of the camera 120, and the control unit 500 is electrically connected with the camera 120 and is used for reading visual identification data of the camera 120. When the camera 120 recognizes the preset pattern of the elastic band 600, the conveying unit stops operating, and at this time, the elastic band 600 stays on the table 100, and then the laser engraving head 110 performs the laser engraving process on the elastic band 600. For example, a plurality of preset patterns are arranged on the elastic belt 600 at intervals along the length direction of the elastic belt 600, the laser engraving head 110 engraves the periphery of the identification pattern of the elastic belt 600, and then the laser engraving head 110 intermittently operates to engrave a pattern on a plurality of parts of the elastic belt 600 with the preset patterns as base points. In some embodiments, the predetermined pattern of the elastic band 600 is one or more of numbers, letters, or graphics. For example, after the preset pattern is a number "0" or a letter "O", the camera 120 recognizes the preset pattern, and uses the center of the "0" or "O" as a positioning base point, and then uses the positioning base point as a processing base point of the laser engraving head 110, to perform laser engraving processing on the elastic band 600.

In some embodiments of the present utility model, as shown in fig. 2, the positioning unit 200 includes a magnetic base 210, the workbench 100 has magnetism, the magnetic base 210 is magnetically connected with the workbench 100, so that the position of the magnetic base 210 can be conveniently adjusted, and further, the conveying position of the elastic belt 600 on the workbench 100 can be adjusted, which is convenient for adjustment. In some embodiments, the magnetic base is used to position the elastic belt, for example, a conveying groove (not shown in the figure) is formed on the magnetic base, and the width of the conveying groove is matched with that of the elastic belt, and the elastic belt is conveyed in the conveying groove. In some embodiments of the present utility model, as shown in fig. 2, there are two magnetic seats 210, the two magnetic seats 210 are arranged at a linear interval, the elastic belt 600 is inserted between the two magnetic seats 210, and two sides of the elastic belt 600 are respectively abutted against the two magnetic seats 210. By adjusting the distance between the opposite side walls of the two magnetic seats 210 to limit the position of the elastic band 600 in the width direction, it is possible to adapt the elastic bands 600 of different widths. In some embodiments, after the elastic bands 600 with different width specifications are limited by the two magnetic bases 210, the center lines of the elastic bands 600 are all at the same position, so that the laser engraving head 110 above the worktable 100 can be better adapted, for example, the laser engraving head 110 is directly and fixedly mounted above the worktable 100 without horizontal movement.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the magnetic base 210 is mounted with a pressing roller 220, the pressing roller 220 is pressed against an upper end surface of the elastic band 600, the magnetic base 210 is provided with a mounting groove 211, the pressing roller 220 is provided with a mounting shaft 221, and the mounting shaft 221 is mounted on the mounting shaft 221. By pressing the elastic band 600 by the pressing roller 220, the elastic band 600 is better limited between the two magnetic seats 210 and is abutted against the opposite side walls of the magnetic seats 210, so that the conveying precision of the elastic band 600 on the workbench 100 is higher, and the occurrence of deflection of the elastic band 600 is reduced. In addition, the object is flatly attached to the section of the engraving process by the press roller 220, so that the engraving effect is ensured. The elastic belt 600 with different widths is a press roller 220 with different widths, in some embodiments, the mounting shaft 221 is made of a magnetic material, and the mounting shaft 221 is magnetically attached to the groove wall of the mounting groove 211 after being placed in the mounting groove 211, so that the press roller 220 is more convenient to detach and replace.

In some embodiments of the present utility model, as shown in fig. 1, the first tape assembly 310 includes a first driving motor, a first driving roller 311, and a first pinch roller 312, the first driving roller 311 and the first pinch roller 312 respectively pressing both sides of the elastic tape 600 and driving the elastic tape 600 to be conveyed toward one side of the table 100; the second belt assembly 320 includes a second driving motor, a second driving roller 321, and a second pinch roller 322, and the second driving roller 321 and the second pinch roller 322 respectively press both sides of the elastic belt 600 and drive the elastic belt 600 to be conveyed toward a side facing away from the table 100. The elastic belt 600 adopts double-drive arrangement, no matter the elastic belt 600 is fed to the workbench 100 and is withdrawn from the workbench 100, the elastic belt 600 is driven by power, the tension of the elastic belt 600 on the workbench 100 can be better regulated and balanced, and the situation that the elastic belt 600 is excessively stretched to cause the thickness of the elastic belt 600 to be thinned is effectively avoided. Further, the first drive motor and the second drive motor rotate differentially. Since the elastic belt 600 has elasticity, if the first driving motor and the second driving motor rotate at the same speed, the elastic belt 600 becomes loose after a period of operation, and therefore, the first driving motor and the second driving motor must be under a balanced tension by a slightly differentiated rotation speed ratio. It should be noted that, the rotation speed ratio of the first driving motor to the second driving motor may be slightly adjusted according to the thickness and the opening of the elastic band 600. In some embodiments, when the rotational speed of the second drive motor is greater than the rotational speed of the first drive motor, the elastic belt 600 is fed from the side of the first belt feed assembly 310 toward the table 100 and is discharged toward the side of the second belt feed assembly 320.

In some embodiments of the present utility model, as shown in fig. 1 and 4, the first tape assembly 410 includes a first driving motor 411, a first connecting disc 412, and a first tape lever 413, where the first tape lever 413 includes a plurality of first tape levers 413 circumferentially arranged on the first connecting disc 412, and the first driving motor 411 is used to drive the first connecting disc 412 to rotate and drive the first tape lever 413 to rotate around a center line of the first connecting disc 412 to repeatedly pick up the elastic tape 600 along a side facing away from the table 100. It should be noted that, instead of hard pulling the elastic belt 600 by the first tape assembly 410, the elastic belt 600 is repeatedly pulled toward the side facing away from the first tape feeding assembly 310 by the first tape lever 413, so that the elastic belt 600 between the first tape assembly 410 and the first tape feeding assembly 310 can be slightly flattened, and the effect of entering the first driving roller 311 is prevented from being affected due to the winding condition of the elastic belt 600. The elastic belt 600 is disposed between the first driving roller 311 and the first pinch roller 312, and is respectively in pressing connection with the first driving roller 311 and the first pinch roller 312. Similarly, the second tape assembly 420 includes a second drive motor, a second connecting disc, and a second tape lever, and the structure and function of the second tape assembly 420 may be referred to the structure and function of the first tape assembly 410, which will not be described in detail herein.
