Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to an adjustable laser cutting machine applied to embroidery machines. Background Technology

[0002] Laser cutting is used for fabric cutting. It avoids contact with the fabric, eliminates blade wear, and offers advantages such as burr-free edges, standardized dimensions, and minimal error, making it widely used in embroidery machines. Embroidery machines often encounter situations where fabric needs to be cut at two or more stations. Current embroidery machines typically employ two or more lasers, each cutting the fabric at one station. However, this method results in a large number of lasers, increasing the manufacturing cost of the embroidery machine.

[0003] For example, Chinese patent application number 201920291954.0, entitled "A Laser Cutting Machine," includes a frame with a worktable and a laser emitting tube mounted on it. The laser emitting tube is housed within a housing. This laser cutting machine uses a reflector to reflect the laser emitted from the laser emitting tube onto the worktable. In existing technologies, to achieve high cutting efficiency, multiple laser cutting heads are used, with each laser tube corresponding to one laser cutting head. However, this also suffers from the problem of a large number of lasers being used, increasing the manufacturing cost of the embroidery machine.

[0004] To address these issues, some embroidery machines currently employ a mobile laser, where a single laser moves back and forth between two or more workstations to cut the fabric at those workstations. While this method effectively reduces the number of lasers used, thereby lowering the manufacturing cost of the embroidery machine, it suffers from several drawbacks. The laser's movement efficiency is low, especially when the distance between the two cutting workstations is significant, which further impacts the cutting efficiency of the fabric at both workstations. Moreover, the fabric cutting at each workstation can only be performed sequentially at different times, making it impossible to cut fabric at multiple workstations simultaneously. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable laser cutting machine for embroidery machines that can not only use a single laser to continuously cut fabric at two cutting stations simultaneously, thereby effectively reducing production costs, but also adjust the laser intensity of the two cutting stations according to actual needs.

[0006] The technical solution of this utility model is:

[0007] An adjustable laser cutting machine for embroidery machines includes a laser, a beam splitter, and a translation drive mechanism. The beam splitter includes two intersecting reflective surfaces. The laser emitted by the laser enters the intersection of the two reflective surfaces, and a portion of the laser beam is reflected by one of the reflective surfaces, while the other portion is reflected by the other, thus splitting the laser beam into two beams. The translation drive mechanism drives the beam splitter to translate, adjusting the size of the laser spot on the two reflective surfaces. This adjustable laser cutting machine for embroidery machines splits a single laser beam into two continuously output laser beams through the two reflective surfaces of the beam splitter. Each laser beam can continuously cut the fabric at one workstation, thus enabling a single laser to simultaneously cut fabric at two cutting workstations, effectively reducing production costs.

[0008] On the other hand, the beam splitter can be moved by a drive mechanism to adjust the size of the laser spot that enters the two reflective mirrors, thereby adjusting the intensity of the laser reflected by the two reflective mirrors. This allows for the adjustment of the laser intensity of the two cutting stations according to actual needs, so as to meet the actual cutting requirements of different stations.

[0009] Preferably, the system also includes a focusing lens and a light guide adjustment device. The focusing lens corresponds one-to-one with the reflecting mirror, and the light guide adjustment device corresponds one-to-one with the focusing lens. The light guide adjustment device includes at least one adjustment lens. The laser light reflected from the reflecting mirror is reflected by the corresponding adjustment lens to the corresponding focusing lens for focusing. In this way, the laser path can be adjusted by the adjustment lens of the light guide adjustment device, thereby adjusting the position of the focusing lens and the cutting area to meet different cutting needs.

[0010] Preferably, a dimming unit is also included, which corresponds one-to-one with the reflecting mirror. Each dimming unit includes a first lens, which is located on the same side of the beam splitter as the laser. The laser reflected by the reflecting mirror is reflected by the corresponding first lens to change the laser direction. In this solution, the dimming mirror not only changes the laser direction to adapt to different laser path layouts, but also compensates for the processing angle errors of the two reflecting mirrors of the beam splitter by adjusting the installation angle of the dimming mirror. This ensures that the laser beam emitted by the laser, after being reflected by the corresponding reflecting mirror and the first lens, can exit at a set azimuth angle. Furthermore, the angle between the two reflecting mirrors of the beam splitter can be changed by adjusting the installation angle of the dimming mirror to adapt to the needs of different beam splitters and improve versatility.

[0011] Preferably, the system also includes a focusing lens and a light guide adjustment device. The focusing lens corresponds one-to-one with the reflecting mirror, and the light guide adjustment device corresponds one-to-one with the focusing lens. The light guide adjustment device includes at least one adjustment lens. The laser light reflected from the reflecting mirror passes through the corresponding first lens and the adjustment lens before being reflected back to the corresponding focusing lens. In this way, the laser path can be adjusted using the adjustment lens of the light guide adjustment device, thereby adjusting the position of the focusing lens and the cutting area to meet different cutting needs.

[0012] Preferably, the dimming unit corresponds one-to-one with the reflecting mirror. Each dimming unit includes a first lens and a second lens. The first lens and the laser are located on the same side of the beam splitter, and the first lens and the laser are located on the same side of the corresponding second lens. The laser reflected by the reflecting mirror passes sequentially through the corresponding first and second lenses to change the laser direction. In this solution, the dimming mirror not only changes the laser direction to adapt to different laser path layouts, but also compensates for the processing angle errors of the two reflecting mirrors of the beam splitter by adjusting the installation angle of the dimming mirror. This ensures that a laser beam emitted by the laser, after being reflected by the corresponding reflecting mirror, the first lens, and the second lens, exits at a set azimuth angle. Furthermore, adjusting the installation angle of the dimming mirror can change the angle between the two reflecting mirrors of the beam splitter to adapt to the needs of different beam splitters and improve versatility.

[0013] Preferably, the system also includes a focusing lens and a light guide adjustment device. The focusing lens corresponds one-to-one with the reflecting mirror, and the light guide adjustment device corresponds one-to-one with the focusing lens. The light guide adjustment device includes at least one adjustment lens. The laser light reflected from the reflecting mirror passes sequentially through the corresponding first lens, second lens, and adjustment lens before being reflected back to the corresponding focusing lens. In this way, the laser path can be adjusted using the adjustment lens of the light guide adjustment device, thereby adjusting the position of the focusing lens and the cutting area to meet different cutting needs.

[0014] Preferably, the two reflecting mirrors are symmetrically distributed.

[0015] Preferably, the translation drive mechanism is an electric cylinder, an electric push rod, a linear module, or a belt transmission mechanism.

[0016] Preferably, the translation drive mechanism includes a sliding mirror base, a lead screw threadedly connected to the sliding mirror base, and a drive motor for driving the lead screw to rotate, wherein the beam splitter is disposed on the sliding mirror base.

[0017] Preferably, a mounting bracket is also included, which is mounted on the frame of the embroidery machine. The laser, beam splitter, and translation drive mechanism are all mounted on the mounting bracket. In this way, the adjustable laser cutting machine can be installed entirely onto the frame of the embroidery machine using the mounting bracket, thus facilitating the actual installation and disassembly of the adjustable laser cutting machine.

[0018] The advantages of this invention are: it can not only use a single laser to continuously cut fabric at two cutting stations simultaneously, thereby effectively reducing production costs; but also allows for adjustment of the laser intensity at the two cutting stations according to actual needs.

[0031] Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, an adjustable laser cutting machine for use in embroidery machines includes a laser 1, a beam splitter 2, and a translation drive mechanism 3.

[0032] The beam splitter 2 includes two reflecting mirrors 2.1 that are at a predetermined angle to each other and intersect.

[0033] The laser emitted by laser 1 is incident at the intersection of two reflecting mirrors 2.1. Part of the laser beam emitted by laser 1 is reflected by one of the reflecting mirrors 2.1, and the other part of the laser beam is reflected by the other reflecting mirror 2.1, thus splitting the laser beam emitted by laser 1 into two laser beams.

[0034] The translation drive mechanism 3 drives the beam splitter 2 to translate, thereby adjusting the size of the laser spot emitted by the laser 1 into the two reflecting mirrors 2.1. The diameter of the laser spot emitted by the laser 1 is typically 2-5 mm. For example, the translation drive mechanism 3 drives the beam splitter 2 to translate, so that the areas of the laser spots emitted by the laser 1 into the two reflecting mirrors 2.1 are the same, or so that the ratio of the areas of the laser spots emitted by the laser 1 into the two reflecting mirrors 2.1 is 1:2, 1:3, or other ratios.

[0035] The translation drive mechanism 3 is an electric cylinder, an electric push rod, a linear module, or a belt conveyor mechanism, which directly drives the beam splitter 2 to translate via the electric push rod, linear module, or belt conveyor mechanism. In this embodiment, the translation drive mechanism 3 includes a sliding mirror base 3.1, a lead screw 3.2 threadedly connected to the sliding mirror base 3.1, and a drive motor 3.3 that drives the lead screw 3.2 to rotate. The beam splitter 2 is fixedly mounted on the sliding mirror base 3.1. The drive motor 3.3 drives the lead screw 3.2 to rotate, thereby driving the sliding mirror base 3.1 and the beam splitter 2 to translate.

[0036] This solution provides an adjustable laser cutting machine for embroidery machines. It uses two reflecting mirrors 2.1 of a beam splitter 2 to split a laser beam emitted by a laser 1 into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, a single laser 1 can be used to continuously cut the fabric at two cutting workstations at the same time, thereby effectively reducing production costs.

[0037] On the other hand, the beam splitter 2 can be translated by the shifting drive mechanism to adjust the size of the laser spot that the laser 1 is injected into the two reflecting mirrors 2.1, thereby adjusting the intensity of the laser reflected through the two reflecting mirrors 2.1. This allows the laser intensity of the two cutting stations to be adjusted according to actual needs, so as to adapt to the actual cutting needs of different stations.

[0038] Specifically, such as Figure 1As shown, an adjustable laser cutting machine for embroidery machines also includes a focusing lens 5 and a light guide adjustment device 4. The focusing lens 5 corresponds one-to-one with the reflecting mirror 2.1. The light guide adjustment device 4 corresponds one-to-one with the focusing lens 5. The light guide adjustment device 4 includes at least one adjustment lens 4.1. In this embodiment, the adjustment lens 4.1 is a reflecting lens. The laser reflected by the reflecting mirror 2.1 is reflected by the corresponding adjustment lens 4.1 to the corresponding focusing lens 5 for focusing. After passing through the focusing lens 5, the laser can cut the fabric on the embroidery machine. Thus, the laser path can be adjusted by the adjustment lens 4.1 of the light guide adjustment device 4, thereby adjusting the position of the focusing lens 5 and the cutting part to adapt to different cutting needs.

[0039] In this embodiment, the laser 1 is located above the beam splitter 2. The apex of the intersection of the two reflecting mirrors 2.1 faces the laser 1. A laser beam emitted by the laser 1 enters vertically at the intersection of the two reflecting mirrors 2.1 of the beam splitter 2. The two reflecting mirrors 2.1 are symmetrically distributed along the vertical direction. The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 is 90 degrees. Thus, the laser beam emitted by the laser 1 is split into two laser beams by the two reflecting mirrors 2.1 of the beam splitter 2, and the two laser beams exit horizontally.

[0040] It should be noted that the positions of laser 1 and beam splitter 2 can also be arranged in other orientations according to actual needs. For example, laser 1 and beam splitter 2 can be arranged in front of each other, and a beam of laser emitted by laser 1 can be horizontally incident on the intersection of the two reflecting mirrors 2.1 of beam splitter 2.

[0041] The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 can also be set to other angles as needed, such as 80 degrees, 100 degrees, 120 degrees, or 130 degrees. The two reflecting mirrors 2.1 can be symmetrically distributed or asymmetrically distributed.

[0042] In this embodiment, as Figure 1 As shown, the translation drive mechanism 3 drives the beam splitter 2 to translate in the horizontal direction, and the direction of movement of the beam splitter 2 is perpendicular to the intersection line of the two reflecting mirror surfaces 2.1.

[0043] It should be noted that the translation direction of the beam splitter 2 driven by the translation drive mechanism 3 can also be set to horizontal translation in other directions according to actual needs. For example, the horizontal translation direction of the beam splitter 2 can be distributed at an angle of 10-80 degrees with the intersection line of the two reflecting mirror surfaces 2.1. Of course, the translation direction of the beam splitter 2 driven by the translation drive mechanism 3 can also be translated in an inclined direction (non-horizontal translation).

[0044] Furthermore, such as Figure 1 , Figure 2As shown, an adjustable laser cutting machine for use in embroidery machines also includes a mounting bracket 6. The mounting bracket 6 is mounted on the frame of the embroidery machine. The laser 1, beam splitter 2, and translation drive mechanism 3 are all mounted on the mounting bracket 6. A sliding mirror mount 3.1 is slidably mounted on the mounting bracket 6. Thus, the adjustable laser cutting machine can be mounted entirely onto the frame of the embroidery machine via the mounting bracket 6, facilitating the actual installation and disassembly of the adjustable laser cutting machine.

[0045] It should be noted that the laser 1, beam splitter 2, and translation drive mechanism 3 can also be directly mounted on the frame of the embroidery machine as needed.

[0046] Furthermore, such as Figure 1 As shown, the light guiding adjustment device 4 also includes a protective tube 4.2, which extends along the path of the laser. Thus, the laser light incident on the light guiding adjustment device 4 will be transmitted within the corresponding protective tube, effectively preventing items or personnel from coming into contact with the laser, thereby protecting the items and operators.

[0047] In actual manufacturing, the adjustment lenses 4.1 of the same light guide adjustment device 4 can be set according to actual needs. For example, there can be one, two, three or more adjustment lenses 4.1 of the same light guide adjustment device 4. In this embodiment, there are two adjustment lenses 4.1 of the same light guide adjustment device 4.

[0048] In one embodiment, the same light guide adjustment device 4 includes two adjustment lenses 4.1, one of which is located above the focusing lens 5. The laser reflected by the reflecting mirror 2.1 is reflected twice by the two adjustment lenses 4.1 of the corresponding light guide adjustment device 4, and then enters the focusing lens 5 from top to bottom for focusing. In this embodiment, the light guide adjustment device 4 has two protective tubes, one located between the two adjustment lenses 4.1, and the other located between the beam splitter 2 and the adjacent adjustment lens 4.1 of the beam splitter 2.

[0049] In another embodiment, the same light guide adjustment device 4 includes an adjustment lens 4.1 located above the focusing lens 5. The laser light reflected by the reflecting mirror 2.1 is reflected by the adjustment lens 4.1 of the corresponding light guide adjustment device 4, and then enters the focusing lens 5 from top to bottom for focusing. In this embodiment, the light guide adjustment device 4 has a single protective tube located between the beam splitter 2 and the adjustment lens 4.1.

[0050] Specific embodiment two, such as Figure 3 As shown, an adjustable laser cutting machine for use in embroidery machines includes a laser 1, a beam splitter 2, a dimming unit 7, and a translation drive mechanism 3.

[0051] The beam splitter 2 includes two reflecting mirrors 2.1 that are at a predetermined angle to each other and intersect.

[0052] The laser emitted by laser 1 is incident at the intersection of two reflecting mirrors 2.1. Part of the laser beam emitted by laser 1 is reflected by one of the reflecting mirrors 2.1, and the other part of the laser beam is reflected by the other reflecting mirror 2.1, thus splitting the laser beam emitted by laser 1 into two laser beams.

[0053] The translation drive mechanism 3 drives the beam splitter 2 to translate, thereby adjusting the size of the laser spot emitted by the laser 1 into the two reflecting mirrors 2.1. The diameter of the laser spot emitted by the laser 1 is typically 2-5 mm. For example, the translation drive mechanism 3 drives the beam splitter 2 to translate, so that the areas of the laser spots emitted by the laser 1 into the two reflecting mirrors 2.1 are the same, or so that the ratio of the areas of the laser spots emitted by the laser 1 into the two reflecting mirrors 2.1 is 1:2, 1:3, or other ratios.

[0054] The translation drive mechanism 3 is an electric cylinder, an electric push rod, a linear module, or a belt conveyor mechanism, which directly drives the beam splitter 2 to translate via the electric push rod, linear module, or belt conveyor mechanism. In this embodiment, the translation drive mechanism 3 includes a sliding mirror base 3.1, a lead screw 3.2 threadedly connected to the sliding mirror base 3.1, and a drive motor 3.3 that drives the lead screw 3.2 to rotate. The beam splitter 2 is fixedly mounted on the sliding mirror base 3.1. The drive motor 3.3 drives the lead screw 3.2 to rotate, thereby driving the sliding mirror base 3.1 and the beam splitter 2 to translate.

[0055] The dimming unit 7 corresponds one-to-one with the reflecting mirror 2.1. The dimming unit 7 includes a first lens 7.1. The first lens 7.1 and the laser 1 are located on the same side of the beam splitter 2. The laser reflected by the reflecting mirror 2.1 is reflected by the corresponding first lens 7.1 to change the direction of the laser.

[0056] This solution provides an adjustable laser cutting machine for embroidery machines. It uses two reflecting mirrors 2.1 of a beam splitter 2 to split a laser beam emitted by a laser 1 into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, a single laser 1 can be used to continuously cut the fabric at two cutting workstations at the same time, thereby effectively reducing production costs.

[0057] On the other hand, the beam splitter 2 can be translated by the shifting drive mechanism to adjust the size of the laser spot that the laser 1 is injected into the two reflecting mirrors 2.1, thereby adjusting the intensity of the laser reflected through the two reflecting mirrors 2.1. This allows the laser intensity of the two cutting stations to be adjusted according to actual needs, so as to adapt to the actual cutting needs of different stations.

[0058] Furthermore, in this embodiment, by setting the dimming unit 7, not only can the laser direction be changed to adapt to the layout requirements of different laser paths, but the error in the processing angle of the two reflecting mirrors 2.1 of the beam splitter 2 can also be compensated by adjusting the installation angle of the dimming unit 7. This ensures that the laser beam emitted by the laser 1, after being reflected by the corresponding reflecting mirror 2.1 and the first lens 7.1, can be emitted at a set azimuth angle. In addition, the angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be changed by adjusting the installation angle of the dimming unit 7 to adapt to the usage requirements of different beam splitters 2, thereby improving versatility.

[0059] Specifically, such as Figure 3 As shown, an adjustable laser cutting machine for embroidery machines also includes a focusing lens 5 and a light guide adjustment device 4. The focusing lens 5 corresponds one-to-one with the reflecting mirror 2.1. The light guide adjustment device 4 corresponds one-to-one with the focusing lens 5. The light guide adjustment device 4 includes at least one adjustment lens 4.1. In this embodiment, the adjustment lens 4.1 is a reflecting lens. The laser reflected by the reflecting mirror 2.1 is reflected by the corresponding first lens 7.1 and the adjustment lens 4.1 to the corresponding focusing lens 5. Thus, the laser path can be adjusted by the adjustment lens 4.1 of the light guide adjustment device 4, thereby adjusting the position of the focusing lens 5 and the cutting part to adapt to different cutting needs.

[0060] In this embodiment, the laser 1 is located above the beam splitter 2. The apex of the intersection of the two reflecting mirrors 2.1 faces the laser 1. A laser beam emitted by the laser 1 enters vertically at the intersection of the two reflecting mirrors 2.1 of the beam splitter 2. The two reflecting mirrors 2.1 are symmetrically distributed along the vertical direction. Thus, the laser beam emitted by the laser 1 is split into two laser beams by the two reflecting mirrors 2.1 of the beam splitter 2. At the same time, the laser beam reflected by the first lens 7.1 can be made to exit horizontally by adjusting the installation angle of the first lens 7.1.

[0061] It should be noted that the positions of laser 1 and beam splitter 2 can also be arranged in other orientations according to actual needs. For example, laser 1 and beam splitter 2 can be arranged in front of each other, and a beam of laser emitted by laser 1 can be horizontally incident on the intersection of the two reflecting mirrors 2.1 of beam splitter 2.

[0062] The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be set to 80 degrees, 100 degrees, 120 degrees, or 130 degrees, etc., as needed. The two reflecting mirrors 2.1 can be symmetrically or asymmetrically distributed.

[0063] In this embodiment, as Figure 3 As shown, the translation drive mechanism 3 drives the beam splitter 2 to translate in the horizontal direction, and the direction of movement of the beam splitter 2 is perpendicular to the intersection line of the two reflecting mirror surfaces 2.1.

[0064] It should be noted that the translation direction of the beam splitter 2 driven by the translation drive mechanism 3 can also be set to horizontal translation in other directions according to actual needs. For example, the horizontal translation direction of the beam splitter 2 can be distributed at an angle of 10-80 degrees with the intersection line of the two reflecting mirror surfaces 2.1. Of course, the translation direction of the beam splitter 2 driven by the translation drive mechanism 3 can also be translated in an inclined direction (non-horizontal translation).

[0065] Furthermore, such as Figure 3 As shown, an adjustable laser cutting machine for use in embroidery machines also includes a mounting bracket 6. The mounting bracket 6 is mounted on the frame of the embroidery machine, and the laser 1, beam splitter 2, and translation drive mechanism 3 are all mounted on the mounting bracket 6. A sliding mirror mount 3.1 is slidably mounted on the mounting bracket 6. Thus, the adjustable laser cutting machine can be installed entirely onto the frame of the embroidery machine via the mounting bracket 6, facilitating the actual installation and disassembly of the adjustable laser cutting machine.

[0066] It should be noted that the laser 1, beam splitter 2, and translation drive mechanism 3 can also be directly mounted on the frame of the embroidery machine as needed.

[0067] Furthermore, such as Figure 3 As shown, the light guiding adjustment device 4 also includes a protective tube 4.2, which extends along the path of the laser. Thus, the laser light incident on the light guiding adjustment device 4 will be transmitted within the corresponding protective tube, effectively preventing items or personnel from coming into contact with the laser, thereby protecting the items and operators.

[0068] In actual manufacturing, the adjustment lenses 4.1 of the same light guide adjustment device 4 can be set according to actual needs. For example, there can be one, two, three or more adjustment lenses 4.1 of the same light guide adjustment device 4. In this embodiment, there are two adjustment lenses 4.1 of the same light guide adjustment device 4.

[0069] In one embodiment, the same light guide adjustment device 4 includes two adjustment lenses 4.1, one of which is located above the focusing lens 5. The laser light reflected by the reflecting mirror 2.1 undergoes two reflections by the two adjustment lenses 4.1 of the corresponding light guide adjustment device 4, and then enters the focusing lens 5 from top to bottom for focusing. In this embodiment, the light guide adjustment device 4 has two protective tubes, one located between the two adjustment lenses 4.1, and the other located between the beam splitter 2 and the adjustment lens 4.1 of the adjacent first lens 7.1.

[0070] In another embodiment, the same light guide adjustment device 4 includes an adjustment lens 4.1 located above the focusing lens 5. The laser light reflected by the reflecting mirror 2.1 is reflected by the adjustment lens 4.1 of the corresponding light guide adjustment device 4, and then enters the focusing lens 5 from top to bottom for focusing. In this embodiment, the light guide adjustment device 4 has a single protective tube located between the first lens 7.1 and the adjustment lens 4.1.

[0071] Specific embodiment three, such as Figure 4 As shown, an adjustable laser cutting machine for use in embroidery machines includes a laser 1, a beam splitter 2, a dimming unit 7, and a translation drive mechanism 3.

[0072] The beam splitter 2 includes two reflecting mirrors 2.1 that are at a predetermined angle to each other and intersect.

[0073] The laser emitted by laser 1 is incident at the intersection of two reflecting mirrors 2.1. Part of the laser beam emitted by laser 1 is reflected by one of the reflecting mirrors 2.1, and the other part of the laser beam is reflected by the other reflecting mirror 2.1, thus splitting the laser beam emitted by laser 1 into two laser beams.

[0074] The translation drive mechanism 3 drives the beam splitter 2 to translate, thereby adjusting the size of the laser spot emitted by the laser 1 into the two reflecting mirrors 2.1. The diameter of the laser spot emitted by the laser 1 is typically 2-5 mm. For example, the translation drive mechanism 3 drives the beam splitter 2 to translate, so that the areas of the laser spots emitted by the laser 1 into the two reflecting mirrors 2.1 are the same, or so that the ratio of the areas of the laser spots emitted by the laser 1 into the two reflecting mirrors 2.1 is 1:2, 1:3, or other ratios.

[0075] The translation drive mechanism 3 is an electric cylinder, an electric push rod, a linear module, or a belt conveyor mechanism, which directly drives the beam splitter 2 to translate via the electric push rod, linear module, or belt conveyor mechanism. In this embodiment, the translation drive mechanism 3 includes a sliding mirror base 3.1, a lead screw 3.2 threadedly connected to the sliding mirror base 3.1, and a drive motor 3.3 that drives the lead screw 3.2 to rotate. The beam splitter 2 is fixedly mounted on the sliding mirror base 3.1. The drive motor 3.3 drives the lead screw 3.2 to rotate, thereby driving the sliding mirror base 3.1 and the beam splitter 2 to translate.

[0076] The dimming unit 7 corresponds one-to-one with the reflecting mirror 2.1. The dimming unit 7 includes a first lens 7.1 and a second lens 7.2. The first lens 7.1 and the laser 1 are located on the same side of the beam splitter 2. The first lens 7.1 and the laser 1 are located on the same side of the corresponding second lens 7.2. The laser light reflected by the reflecting mirror 2.1 is reflected sequentially by the corresponding first lens 7.1 and second lens 7.2 to change the laser direction.

[0077] This solution provides an adjustable laser cutting machine for embroidery machines. It uses two reflecting mirrors 2.1 of a beam splitter 2 to split a laser beam emitted by a laser 1 into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, a single laser 1 can be used to continuously cut the fabric at two cutting workstations at the same time, thereby effectively reducing production costs.

[0078] On the other hand, the beam splitter 2 can be translated by the shifting drive mechanism to adjust the size of the laser spot that the laser 1 is injected into the two reflecting mirrors 2.1, thereby adjusting the intensity of the laser reflected through the two reflecting mirrors 2.1. This allows the laser intensity of the two cutting stations to be adjusted according to actual needs, so as to adapt to the actual cutting needs of different stations.

[0079] Furthermore, in this embodiment, by setting the dimming unit 7, not only can the laser direction be changed to adapt to the layout requirements of different laser paths, but the error in the processing angle of the two reflecting mirrors 2.1 of the beam splitter 2 can also be compensated by adjusting the installation angle of the dimming unit 7. This ensures that the laser beam emitted by the laser 1, after being reflected by the corresponding reflecting mirror 2.1, the first lens 7.1, and the second lens 7.2, can be emitted at a set azimuth angle. In addition, the angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be changed by adjusting the installation angle of the dimming unit 7 to adapt to the usage requirements of different beam splitters 2, thereby improving versatility.

[0080] Specifically, such as Figure 4 As shown, an adjustable laser cutting machine for embroidery machines also includes a focusing lens 5 and a light guide adjustment device 4. The focusing lens 5 corresponds one-to-one with the reflecting mirror 2.1. The light guide adjustment device 4 corresponds one-to-one with the focusing lens 5. The light guide adjustment device 4 includes at least one adjustment lens 4.1. In this embodiment, the adjustment lens 4.1 is a reflecting lens. The laser reflected by the reflecting mirror 2.1 passes sequentially through the corresponding first lens 7.1, second lens 7.2, and adjustment lens 4.1 before being reflected back to the corresponding focusing lens 5. Thus, the laser path can be adjusted using the adjustment lens 4.1 of the light guide adjustment device 4, thereby adjusting the position of the focusing lens 5 and the cutting area to adapt to different cutting needs.

[0081] In this embodiment, the laser 1 is located above the beam splitter 2. The apex of the intersection of the two reflecting mirrors 2.1 faces the laser 1. A laser beam emitted by the laser 1 enters vertically at the intersection of the two reflecting mirrors 2.1 of the beam splitter 2. The two reflecting mirrors 2.1 are symmetrically distributed along the vertical direction. Thus, the laser beam emitted by the laser 1 is split into two laser beams by the two reflecting mirrors 2.1 of the beam splitter 2. At the same time, by adjusting the installation angle of the first lens 7.1 and the second lens 7.2, the laser beam reflected by the first lens 7.1 and the second lens 7.2 can be emitted horizontally.

[0082] It should be noted that the positions of laser 1 and beam splitter 2 can also be arranged in other orientations according to actual needs. For example, laser 1 and beam splitter 2 can be arranged in front of each other, and a beam of laser emitted by laser 1 can be horizontally incident on the intersection of the two reflecting mirrors 2.1 of beam splitter 2.

[0083] The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be set to 80 degrees, 100 degrees, 120 degrees, or 130 degrees, etc., as needed. The two reflecting mirrors 2.1 can be symmetrically or asymmetrically distributed.

[0084] In this embodiment, as Figure 4 As shown, the translation drive mechanism 3 drives the beam splitter 2 to translate in the horizontal direction, and the direction of movement of the beam splitter 2 is perpendicular to the intersection line of the two reflecting mirror surfaces 2.1.

[0085] It should be noted that the translation direction of the beam splitter 2 driven by the translation drive mechanism 3 can also be set to horizontal translation in other directions according to actual needs. For example, the horizontal translation direction of the beam splitter 2 can be distributed at an angle of 10-80 degrees with the intersection line of the two reflecting mirror surfaces 2.1. Of course, the translation direction of the beam splitter 2 driven by the translation drive mechanism 3 can also be translated in an inclined direction (non-horizontal translation).

[0086] Furthermore, such as Figure 4 As shown, an adjustable laser cutting machine for use in embroidery machines also includes a mounting bracket 6. The mounting bracket 6 is mounted on the frame of the embroidery machine, and the laser 1, beam splitter 2, and translation drive mechanism 3 are all mounted on the mounting bracket 6. A sliding mirror mount 3.1 is slidably mounted on the mounting bracket 6. Thus, the adjustable laser cutting machine can be installed entirely onto the frame of the embroidery machine via the mounting bracket 6, facilitating the actual installation and disassembly of the adjustable laser cutting machine.

[0087] It should be noted that the laser 1, beam splitter 2, and translation drive mechanism 3 can also be directly mounted on the frame of the embroidery machine as needed.

[0088] Furthermore, such as Figure 4As shown, the light guiding adjustment device 4 also includes a protective tube 4.2, which extends along the path of the laser. Thus, the laser light incident on the light guiding adjustment device 4 will be transmitted within the corresponding protective tube, effectively preventing items or personnel from coming into contact with the laser, thereby protecting the items and operators.

[0089] In actual manufacturing, the adjustment lenses 4.1 of the same light guide adjustment device 4 can be set according to actual needs. For example, there can be one, two, three or more adjustment lenses 4.1 of the same light guide adjustment device 4. In this embodiment, there are two adjustment lenses 4.1 of the same light guide adjustment device 4.

[0090] In one embodiment, the same light guide adjustment device 4 includes two adjustment lenses 4.1, one of which is located above the focusing lens 5. The laser reflected by the reflecting mirror 2.1 is reflected twice by the two adjustment lenses 4.1 of the corresponding light guide adjustment device 4, and then enters the focusing lens 5 from top to bottom for focusing. In this embodiment, the light guide adjustment device 4 has two protective tubes, one located between the two adjustment lenses 4.1, and the other located between the beam splitter 2 and the adjustment lens 4.1 of the adjacent second lens 7.2.

[0091] In another embodiment, the same light guide adjustment device 4 includes an adjustment lens 4.1 located above the focusing lens 5. The laser light reflected by the reflecting mirror 2.1 is reflected by the adjustment lens 4.1 of the corresponding light guide adjustment device 4, and then enters the focusing lens 5 from top to bottom for focusing. In this embodiment, the light guide adjustment device 4 has a single protective tube located between the second lens 7.2 and the adjustment lens 4.1.

[0092] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
