Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a focal length adjustment mechanism for a labeling machine. Background Art

[0002] Before laser printing, the label machine needs to focus according to the distance from the steel belt. When the thickness of the steel belt changes, the distance between the engraving surface and the scanning galvanometer will change. Therefore, the quickest way to deal with it is to move the scanning galvanometer so that the distance between it and the engraving surface is reset to a preset distance. For this reason, the existing scanning galvanometer generally has a lifting and adjustment function. However, due to the large structure of the scanning galvanometer itself, after reserving the lifting and moving range, the overall height of the label machine will be larger, and the stability will be poor. Utility Model Content

[0003] In order to solve the problem of unreasonable adjustment method of the above-mentioned labeling machine, the utility model provides a focal length adjustment mechanism for the labeling machine.

[0004] The technical solution of this utility model is as follows:

[0008] Different from the existing labeling machines, by additionally setting a light guide arm, the laser head can be set at other positions, the position relative to the scanning galvanometer is optional, and can be selected according to actual application conditions.

[0009] The lifting platform is arranged in a horizontal manner, and the moving direction is perpendicular to the upper surface of the transport platform. The distance between the scanning galvanometer and the steel belt engraving plane can be directly adjusted by moving the lifting platform.

[0010] As a preferred solution, the scanning galvanometer and the laser head are both arranged vertically relative to the light guide arm, and the scanning galvanometer, the light guide arm and the laser head are located in the same horizontal plane.

[0013] For the convenience of adjustment, the length direction of the laser head is parallel to the vertical plate, and the distance relative to the light guide arm can be adjusted. The position of the laser head can be adjusted according to needs and is convenient for maintenance.

[0027] like Figure 1-4 The focal length adjustment mechanism of a labeling machine shown in the figure includes a transport platform 3 arranged on a horizontal bottom plate 1. The transport platform 3 can transport the steel belt. For this purpose, the upper surface of the transport platform 3 is a plane to prevent the steel belt from bending so that it cannot be engraved and display better label information. The steel belt 4 passes through the top of the transport platform 3 and is transported by the transport platform 3. During the transportation process, the steel belt always remains in a horizontal state to ensure that the marked information can be normally marked in the correct position.

[0028] In the above structure, in order to perform laser marking operations, a scanning galvanometer 5 is arranged directly above the transport platform 3. The scanning galvanometer 5 is oriented perpendicular to the upper surface of the transport platform 3, so that the steel belt placed above the transport platform 3 can be marked, and there is no obstruction between the scanning galvanometer 5 and the transport platform 3 except the steel belt 4, so as to ensure that there will be no obstruction blocking the laser operation. However, the scanning galvanometer 5 cannot complete the marking operation alone, and a laser head 7 needs to be set. Under normal circumstances, the laser head 7 will be located on one side of the scanning galvanometer 5 and is set toward the scanning galvanometer 5. Therefore, more workpieces need to be reserved on one side of the scanning galvanometer 5 for setting the laser head 7, which results in a larger overall height of the equipment.

[0029] For this reason, Figure 1 , 2As shown, the bottom plate 1 is also vertically provided with a vertical plate 2, and the vertical plate 2 is used to divide the area above the bottom plate 1, so that different components can be placed in different positions, and in the above structure, a lifting platform 8 is provided on the side of the vertical plate 2 away from the scanning galvanometer 5, and the lifting platform 8 is used to adjust the overall height of the scanning galvanometer 5 and its related connecting parts, so as to ensure that when the steel belts of different thicknesses are replaced, the scanning galvanometer 5 can quickly adjust the height with the lifting platform 8 and keep the distance from the upper surface of the steel belt constant, so as to ensure that the focal length is always a constant value, so as to ensure In order to ensure the accuracy and clarity of the marked information, it should be noted that the above-mentioned lifting platform 8 is provided with a light guide arm 6 and a laser head 7, and the light guide arm 6 passes through the vertical plate 2 and is connected to the scanning galvanometer 5, and is relatively fixed. Under normal circumstances, general staff will choose the laser head 7 to face and connect to the scanning galvanometer 5. However, due to the large length of the laser head 7, when ensuring that it faces the scanning galvanometer 5, its overall width will be limited and cannot be reduced. In order to avoid the above-mentioned problems and facilitate the adjustment of the distance between the laser head 7 and the scanning galvanometer 5, the design of the above-mentioned light guide arm 6 is very necessary.

[0030] In the above structure, the lifting platform 8 is arranged in a horizontal manner, and the moving direction is perpendicular to the upper surface of the transport platform 3. By adopting the above design, the lifting platform 8 can directly adjust the distance between the scanning galvanometer 5 and the marking plane of the steel belt 4.

[0031] In the above structure, the lifting platform 8 is adjusted by controlling the lifting and lowering of the lifting platform 8 through the adjusting member 9. The end of the adjusting member 9 is arranged outside the device, and can be directly rotated manually or electrically.

[0032] If manual rotation is adopted, the specific structure of the above-mentioned adjusting member 9 is that the adjusting member 9 is a rotating screw rod which is fixed in position and vertically arranged, and the lifting platform 8 is sleeved on the screw rod through the screw rod seat. Under the premise that the position of the adjusting member 9 is fixed relative to the vertical plate 2, it only needs to be rotated, and the screw rod seat will move relative to the vertical plate 2, and through the above-mentioned movement, the lifting platform 8 can be driven to adjust the position in the vertical direction, so as to adjust the distance between the scanning galvanometer 5 and the upper surface of the steel belt 4.

[0033] like Figure 3 , 4 As shown, as a preferred solution, the scanning galvanometer 5 and the laser head 7 are both vertically arranged relative to the light guide arm 6, and the scanning galvanometer 5, the light guide arm 6 and the laser head 7 are located in the same horizontal plane.

[0034] Afterwards, in order to adjust the marking position, the spacing of the scanning galvanometer 5 relative to the light guide arm 6 can be adjusted, and the adjustment direction is perpendicular to the vertical plate 2. By adopting the above connection method, the position of the scanning galvanometer 5 relative to the steel belt can be changed, and the same information can be marked at different positions, with a higher degree of freedom. Therefore, when different information needs to be marked, adaptive adjustment can be made according to needs.

[0035] Through the above structure, it can be realized that, different from the existing labeling machine, by additionally setting the light guide arm 6, the laser head 7 can be set in other positions, and the position relative to the scanning galvanometer 5 is optional and can be selected according to the actual application situation. And there are two adjustment directions, namely the horizontal direction and the vertical direction, which can respectively realize the change of the position of the engraved information and the application of steel strips of different thicknesses, so it has strong applicability, and the above structural components have a high degree of freedom in setting, and can reduce the height and width to a certain extent, thereby realizing the reasonable application of space.

[0036] In addition to the above structure, as a preferred solution, the scanning galvanometer 5, the light guide arm 6 and the laser head 7 are respectively located on both sides of the vertical plate 2. Avoid occupying each other's position, and be able to perform maintenance operations on some structures under the condition of complementary interference. In order to disassemble and assemble some parts separately, the scanning galvanometer 5, the light guide arm 6 and the laser head 7 are respectively detachably connected to the lifting platform 8. According to needs, some parts can be disassembled and assembled without all of them. If any part is damaged, it can be disassembled and replaced separately, and the position is constant after installation, so it can continue to be used.

[0037] Finally, for the convenience of adjustment, the length direction of the laser head 7 is parallel to the vertical plate 2, and the distance relative to the light guide arm 6 can be adjusted. The position of the laser head 7 can be adjusted according to the needs and is convenient for maintenance. Figure 3 As shown, if the laser head 7 is set in an inclined state, it will take up more space and cause waste of space, while adopting a horizontal setting mode can avoid this problem.

[0038] In order to improve the function of the above-mentioned labeling machine and ensure that it can be used in any position, as a preferred solution, the bottom plate 1 is rotatably provided with a steel belt 4 roll on the side of the vertical plate 2 close to the transport platform 3, and a storage battery is provided on the side of the vertical plate 2 away from the transport platform 3. According to the needs, all components can be arranged in a limited space. When using, it can be used directly after only confirming the label information.
