Description

Technical Field

[0001] This utility model relates to the field of fabric laser cutting technology, specifically to an adjustable multi-path laser cutting device for embroidery machines. Background Technology

[0002] Currently, laser cutting devices are widely used in embroidery machines for fabric cutting. Laser cutting does not come into contact with the fabric, eliminating blade wear issues and resulting in burr-free edges, standardized dimensions, and minimal error. When using laser cutting devices in embroidery machines, it is often necessary to cut fabric at multiple stations. Currently, one laser cutting device is typically used for each station, leading to a large number of laser cutting devices and increasing the manufacturing cost of the embroidery machine.

[0003] On the other hand, unlike regular fabric cutting, the fabric cut in embroidery machines often has two layers: a face fabric and a back fabric. When using laser cutting, only the face fabric is cut, not the back fabric. Therefore, there are strict requirements on the actual cutting power of the laser cutting device. If the actual cutting power is too high, it is easy to cut into the back fabric; if the actual cutting power is too low, the face fabric may not be cut properly. Currently, the laser cutting devices used in embroidery machines generally include a focusing element (such as a focusing lens) and a laser path adjustment assembly. The laser path adjustment assembly includes several mirrors arranged sequentially along the laser path. The laser emitted by the laser is reflected by these mirrors to the focusing element for focusing, thereby achieving cutting of the fabric below the focusing element. During the actual installation and manufacturing process of laser cutting equipment, due to manufacturing errors in the output power of the laser itself, as well as errors in the installation positions of the laser, focusing element, and laser path adjustment components, the optical paths of the lasers used in different laser cutting devices in the same embroidery machine are different. This affects the accuracy and consistency of the actual cutting power of the laser cutting device, resulting in problems such as the actual laser cutting power being too high or too low.

[0004] For example, Chinese Patent Publication No. CN218426248U, entitled "A Rotation Adjustable Laser Cutter for an Embroidery Machine," describes a laser that can emit multiple laser beams (i.e., the same laser cutting device can emit multiple laser beams) to cut fabric at different workstations. However, there may be errors in the installation positions of the focusing elements and reflectors of the laser path adjustment components for each laser beam. This results in differences in the optical paths of the laser beams emitted by the same laser, making it difficult to adjust the actual cutting power of each laser beam to be consistent. Consequently, the actual cutting power may be too high or too low. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable multi-path laser cutting device for embroidery machines. This device can not only cut fabric at two cutting stations simultaneously using the same laser generator, reducing the number of laser generators required and saving costs, but also adjust the actual laser cutting power to ensure the accuracy and consistency of the actual laser cutting power at different cutting stations in the embroidery machine. This effectively solves the problem of the actual laser cutting power being too high or too low due to errors in the output power of the laser generator itself and differences in the laser's optical path.

[0006] The technical solution of this utility model is: An adjustable multi-path laser cutting device for an embroidery machine includes: Laser generator; Two laser adjustment units, each laser adjustment unit includes a rotating adjustment component and a dimming hole provided on the adjustment component; A beam splitter divides a laser beam emitted by a laser generator into two beams. Each beam passes through a dimming aperture of a laser adjustment unit, and the cross-sectional area of ​​the laser beam passing through the dimming aperture is adjusted by rotating the adjustment component of the laser adjustment unit. In practical operation, this adjustable multi-path laser cutting device for an embroidery machine uses a beam splitter to divide a single laser beam into two beams. Each beam can cut the fabric at one cutting station, allowing simultaneous cutting of fabric at two stations using the same laser generator. This reduces the number of laser generators required, saving costs, and enables simultaneous cutting of fabric at multiple stations, ensuring high production efficiency.

[0007] On the other hand, in practical applications, the cross-sectional area of ​​the laser passing through the dimming aperture can be adjusted by rotating the adjustment component of the laser adjustment unit, thereby adjusting the actual laser cutting power (the larger the cross-sectional area of ​​the laser passing through the dimming aperture, the greater the actual laser cutting power; conversely, the smaller the cross-sectional area of ​​the laser passing through the dimming aperture, the smaller the actual laser cutting power). This ensures the accuracy and consistency of the actual laser cutting power at different cutting stations in the embroidery machine, effectively improving the cutting quality of the embroidery fabric and solving the problem of the actual laser cutting power being too high or too low due to the inherent error in the laser's output power and the differences in the laser's optical path.

[0008] Furthermore, the actual cutting power of the laser can be adjusted by changing the cross-sectional area of ​​the laser passing through the dimming aperture, thus adapting to the actual cutting needs of different fabrics and improving the versatility of the laser cutting equipment. At the same time, adjusting the cross-sectional area of ​​the laser passing through the dimming aperture is convenient, simple in structure, and low in manufacturing cost, which helps to save on production costs.

[0009] Preferably, the laser adjustment unit also includes an adjustment support, and the adjustment component is threadedly connected to the adjustment support. Thus, by manually rotating the adjustment component, the cross-sectional area of ​​the laser passing through the adjustment hole can be adjusted through the rotation of the adjustment hole and the axial movement of the thread, thereby adjusting the actual laser cutting power.

[0010] Preferably, the adjusting component is made of bolts, with the dimming hole penetrating the bolt's threaded shaft radially. This facilitates the actual fabrication of the adjusting component and reduces manufacturing costs.

[0011] Preferably, the laser adjustment unit also includes an adjustment support and a drive motor mounted on the adjustment support. The adjustment component is rotatably mounted on the adjustment support, and the drive motor drives the adjustment component to rotate. In this way, the cross-sectional area of ​​the laser passing through the dimming aperture can be automatically adjusted by driving the adjustment component to rotate, thereby adjusting the actual laser cutting power.

[0012] Preferably, a mounting bracket is also included, on which the beam splitter is fixedly mounted. This facilitates the installation of the beam splitter.

[0013] As a preferred option, it also includes: Two focusing elements; The laser path adjustment assembly corresponds one-to-one with the focusing element, and includes at least one reflector. The two laser beams split by the beam splitter are focused by the corresponding focusing elements after passing through the mirrors of the corresponding laser path adjustment components. Each laser adjustment unit corresponds one-to-one with a focusing element, and the dimming aperture of the laser adjustment unit is arranged on the laser path between the beam splitter and the corresponding focusing element. In this way, the laser path can be adjusted by the reflector of the laser path adjustment assembly, thereby adjusting the position of the focusing lens and the cutting part to meet different cutting needs.

[0014] An adjustable multi-path laser cutting device for an embroidery machine includes: Laser generator; Two laser adjustment units, each laser adjustment unit includes an adjustment component, a dimming hole provided on the adjustment component, and a translation mechanism for driving the adjustment component to move; A beam splitter divides a single laser beam emitted by a laser generator into two beams. Each beam passes through a dimming aperture of a laser adjustment unit. A translation mechanism drives the adjustment component to move, adjusting the cross-sectional area of ​​the laser beam passing through the dimming aperture. In practical operation, this adjustable multi-path laser cutting device for an embroidery machine uses a beam splitter to divide a single laser beam into two beams. Each beam can cut the fabric at one cutting station, allowing simultaneous cutting of fabric at two stations using the same laser generator. This reduces the number of laser generators required, saving costs, and enables simultaneous cutting of fabric at multiple stations, ensuring high production efficiency.

[0015] On the other hand, in practical applications, a translation mechanism can drive the adjustment component to move, thereby adjusting the cross-sectional area of ​​the laser passing through the dimming aperture, and thus adjusting the actual laser cutting power (the larger the cross-sectional area of ​​the laser passing through the dimming aperture, the greater the actual laser cutting power; conversely, the smaller the cross-sectional area of ​​the laser passing through the dimming aperture, the smaller the actual laser cutting power). This ensures the accuracy and consistency of the actual laser cutting power at different cutting stations in the embroidery machine, effectively improving the cutting quality of the embroidery fabric and solving the problem of the actual laser cutting power being too high or too low due to the inherent error in the laser's output power and the differences in the laser's optical path.

[0016] Furthermore, the actual cutting power of the laser can be adjusted by changing the cross-sectional area of ​​the laser passing through the dimming aperture, thus adapting to the actual cutting needs of different fabrics and improving the versatility of the laser cutting equipment. At the same time, adjusting the cross-sectional area of ​​the laser passing through the dimming aperture is convenient, simple in structure, and low in manufacturing cost, which helps to save on production costs.

[0017] Preferably, the laser adjustment unit also includes an adjustment support, on which the translation mechanism is mounted. This facilitates the installation of the laser adjustment unit.

[0018] Preferably, a mounting bracket is also included, on which the beam splitter is fixedly mounted. This facilitates the installation of the beam splitter.

[0019] As a preferred option, it also includes: Two focusing elements; The laser path adjustment assembly corresponds one-to-one with the focusing element, and includes at least one reflector. The two laser beams split by the beam splitter are focused by the corresponding focusing elements after passing through the mirrors of the corresponding laser path adjustment components. Each laser adjustment unit corresponds one-to-one with a focusing element, and the dimming aperture of the laser adjustment unit is arranged on the laser path between the beam splitter and the corresponding focusing element. In this way, the laser path can be adjusted by the reflector of the laser path adjustment assembly, thereby adjusting the position of the focusing lens and the cutting part to meet different cutting needs.

[0020] The beneficial effects of this utility model are: Firstly, in practical work, a beam splitter is used to split the laser beam emitted by the laser generator into two beams. Each beam can cut the fabric at one cutting station, thus enabling the same laser generator to cut the fabric at two stations of the embroidery machine simultaneously. This reduces the number of laser generators used, saving costs, and allows the fabric at multiple stations to be cut simultaneously, ensuring production efficiency.

[0021] Secondly, in practical applications, the cross-sectional area of ​​the laser passing through the dimming aperture can be adjusted by the adjustment components of the laser adjustment unit, thereby adjusting the actual laser cutting power (the larger the cross-sectional area of ​​the laser passing through the dimming aperture, the greater the actual laser cutting power; conversely, the smaller the cross-sectional area of ​​the laser passing through the dimming aperture, the smaller the actual laser cutting power). This ensures the accuracy and consistency of the actual laser cutting power at different cutting stations in the embroidery machine, effectively improving the cutting quality of the embroidery fabric and solving the problem of the actual laser cutting power being too high or too low due to the inherent error in the laser's output power and the differences in the laser's optical path.

[0025] Figure 4 This is a partial enlarged view of an adjustable multi-path laser cutting device for an embroidery machine, which is a specific embodiment of the present invention.

[0026] In the picture: Laser generator 1; Beam splitter 2; Laser adjustment unit 3, adjustment component 3.1, dimming hole 3.2, adjustment support 3.3, translation mechanism 3.4; Focusing element 4; Laser path adjustment component 5, reflector 5.1, outer protective tube 5.2; Mounting support 6. Detailed Implementation

[0027] Specific Implementation Example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, an adjustable multi-path laser cutting device for embroidery machines includes a laser generator 1, two laser adjustment units 3, and a beam splitter 2. The laser emitted by the laser generator 1 used in embroidery machines typically has a cross-sectional area diameter of 2-8 mm. However, the application range of the movable dimming laser cutting machine for embroidery machines in this embodiment is not limited to lasers with a diameter of 2-8 mm.

[0028] The laser adjustment unit 3 includes an adjustment component 3.1 that is rotatably mounted and a dimming hole 3.2 mounted on the adjustment component 3.1.

[0029] Beam splitter 2 divides a laser beam emitted by laser generator 1 into two beams. Two laser adjustment units 3 correspond one-to-one with the two beams split by beam splitter 2. The two beams split by beam splitter 2 each pass through the dimming aperture 3.2 of their corresponding laser adjustment unit 3. The cross-sectional area of ​​the laser beam passing through the dimming aperture 3.2 is adjusted by rotating the adjustment component 3.1 of the laser adjustment unit 3. The aperture of the dimming aperture 3.2 is greater than or equal to the diameter of the laser beam split by beam splitter 2. The larger the cross-sectional area of ​​the laser beam passing through the dimming aperture 3.2, the greater the actual cutting power of the laser; conversely, the smaller the cross-sectional area of ​​the laser beam passing through the dimming aperture 3.2, the smaller the actual cutting power of the laser beam. Specifically, by rotating the adjustment component 3.1 of the laser adjustment unit 3, the laser beam can be made to pass completely through the dimming aperture 3.2 or partially blocked by the adjustment component 3.1, thereby adjusting the cross-sectional area of ​​the laser beam passing through the dimming aperture 3.2.

[0030] In this embodiment, an adjustable multi-path laser cutting device for an embroidery machine splits a single laser beam emitted by the laser generator 1 into two beams using a beam splitter 2. Each beam can cut the fabric at one cutting station, thus enabling the same laser generator 1 to simultaneously cut the fabric at two stations of the embroidery machine. This reduces the number of laser generators 1 required, saving costs, and allows for simultaneous cutting of fabric at multiple stations, ensuring production efficiency.

[0031] On the other hand, in practical applications, the cross-sectional area of ​​the laser passing through the dimming hole 3.2 can be adjusted by rotating the adjusting component 3.1 of the laser adjusting unit 3, thereby adjusting the actual cutting power of the laser (the larger the cross-sectional area of ​​the laser passing through the dimming hole 3.2, the greater the actual cutting power of the laser; conversely, the smaller the cross-sectional area of ​​the laser passing through the dimming hole 3.2, the smaller the actual cutting power of the laser). This ensures the accuracy and consistency of the actual cutting power of the laser at different cutting stations in the embroidery machine, effectively improving the cutting quality of the embroidery fabric and solving the problem of the actual cutting power of the laser being too high or too low due to the output power error of the laser itself and the difference in the laser's optical path.

[0032] Furthermore, the actual cutting power of the laser can be adjusted by changing the cross-sectional area of ​​the laser passing through the dimming hole 3.2, thus adapting to the actual cutting needs of different fabrics and improving the versatility of the laser cutting equipment. At the same time, adjusting the cross-sectional area of ​​the laser passing through the dimming hole 3.2 is convenient, simple in structure, and low in manufacturing cost, which helps to save on production costs.

[0033] Specifically, such as Figure 1 , Figure 2 As shown, an adjustable multi-path laser cutting device for an embroidery machine further includes two focusing elements 4 and a laser path adjustment component 5. The laser generator 1, focusing elements 4, and laser path adjustment component 5 are all mounted on the frame of the embroidery machine. The focusing element 4 is a focusing lens. The laser generator 1, focusing elements 4, and laser path adjustment component 5 can each be mounted individually on the frame, or they can be first mounted on the same bracket, and then the laser generator 1, focusing elements 4, and laser path adjustment component 5 of the multi-path laser cutting device for an embroidery machine are mounted together on the frame via the bracket.

[0034] The laser path adjustment component 5 corresponds one-to-one with the focusing element 4. The laser path adjustment component 5 also corresponds one-to-one with the two laser beams split by the beam splitter 2. The laser path adjustment component 5 includes at least one reflector 5.1. For example, the laser path adjustment component 5 includes 2-5 reflectors 5.1; the specific number and installation position of the reflectors 5.1 are adjusted and determined according to the actual cutting station position. The two laser beams split from the beam splitter 2 are focused by the corresponding focusing element 4 after passing through the reflector 5.1 of the laser path adjustment component 5. In this way, the laser path can be adjusted by the reflector 5.1 of the laser path adjustment component 5, thereby adjusting the position of the focusing lens and the cutting part to meet different cutting needs.

[0035] The laser adjustment unit 3 corresponds one-to-one with the focusing element 4. The dimming aperture 3.2 of the laser adjustment unit 3 is arranged on the laser path between the beam splitter 2 and the corresponding focusing element 4. That is, the dimming aperture 3.2 of the laser adjustment unit 3 can be arranged at any position on the laser path between the beam splitter 2 and the corresponding focusing element 4.

[0036] In one example, such as Figure 2 , Figure 3 As shown, the dimming aperture 3.2 of the laser adjustment unit 3 is close to the beam splitter 2. This facilitates the arrangement and actual installation of the laser adjustment unit 3.

[0037] In one embodiment of this example, such as Figure 2 , Figure 3 As shown, laser generator 1 emits a laser beam from top to bottom through its laser emission port. Beam splitter 2 is located below the laser emission port of laser generator 1. Beam splitter 2 splits the laser beam emitted by laser generator 1 into two laser beams. One of the two laser beams emitted by beam splitter 2 is emitted horizontally, and the other is emitted vertically downwards.

[0038] It should be noted that the angles of the two laser beams split by beam splitter 2 can be adjusted according to actual needs. For example, one laser beam can be at an angle of 0-45 degrees to the horizontal plane, and the other laser beam can be at an angle of 60-120 degrees to the horizontal plane.

[0039] Furthermore, such as Figure 1 As shown, the laser path adjustment component 5 also includes an outer protective tube 5.2 distributed along the laser path. The two laser beams split by the beam splitter 2 are transmitted within the corresponding outer protective tube 5.2 of the laser path adjustment component 5. In this way, on the one hand, the outer protective tube 5.2 can ensure that the laser path is not blocked by foreign objects, and on the other hand, it can effectively prevent objects or personnel from coming into contact with the laser, thereby protecting the objects and operators.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, an adjustable multi-path laser cutting device for an embroidery machine also includes a mounting bracket 6. The mounting bracket 6 is mounted on the housing of the laser generator 1 at the laser emission port. The beam splitter 2 is fixedly mounted on the mounting bracket 6. This facilitates the installation of the beam splitter 2.

[0041] In this embodiment, the cross-sectional area of ​​the laser passing through the dimming aperture 3.2 is adjusted by rotating the adjusting component 3.1 of the laser adjusting unit 3. Specifically, In one implementation, such as Figure 2 , Figure 3As shown, the laser adjustment unit 3 also includes an adjustment support 3.3. The adjustment component 3.1 is threadedly connected to the adjustment support 3.3. Thus, by manually rotating the adjustment component 3.1, the cross-sectional area of ​​the laser passing through the adjustment hole 3.2 can be adjusted by rotating the adjustment hole 3.2 and moving the thread axially, thereby adjusting the actual laser cutting power.

[0042] In this embodiment, the adjusting support 3.3 is installed on the adjusting support 3.3 by means of threads.

[0043] In one example, such as Figure 3 As shown, the adjusting component 3.1 is made of bolts, and the adjusting hole 3.2 passes through the bolt's threaded shaft radially. This facilitates the actual manufacturing of the adjusting component 3.1 and reduces manufacturing costs. The adjusting support 3.3 is also equipped with a scale distributed around the bolt's circumference, and the bolt end has an indicator line corresponding to the scale.

[0044] In another embodiment, the laser adjustment unit 3 further includes an adjustment support 3.3 and a drive motor mounted on the adjustment support 3.3. An adjustment member 3.1 is rotatably mounted on the adjustment support 3.3, and the drive motor drives the adjustment member 3.1 to rotate (not shown in the figure). The adjustment member 3.1 is rod-shaped, block-shaped, or has other shapes. Thus, by driving the adjustment member 3.1 to rotate via the drive motor, the cross-sectional area of ​​the laser passing through the dimming aperture 3.2 can be automatically adjusted, thereby adjusting the actual laser cutting power.

[0045] Specific embodiment two, such as Figure 1 , Figure 4 As shown, an adjustable multi-path laser cutting device for embroidery machines includes a laser generator 1, two laser adjustment units 3, and a beam splitter 2. The laser emitted by the laser generator 1 used in embroidery machines typically has a cross-sectional area diameter of 2-8 mm. However, the application range of the movable dimming laser cutting machine for embroidery machines in this embodiment is not limited to lasers with a diameter of 2-8 mm.

[0046] The laser adjustment unit 3 includes an adjustment component 3.1, a dimming hole 3.2 disposed on the adjustment component 3.1, and a translation mechanism 3.4 for driving the adjustment component 3.1 to move. In this embodiment, the adjustment component 3.1 may be rod-shaped, plate-shaped, block-shaped, or other shapes. The translation mechanism 3.4 is a linear motor, linear module, electric cylinder, or electric push rod.

[0047] Beam splitter 2 splits the laser beam emitted by laser generator 1 into two beams. The two beams from beam splitter 2 each pass through a dimming aperture 3.2 of a laser adjustment unit 3. Translation mechanism 3.4 drives adjustment component 3.1 to move, thereby adjusting the cross-sectional area of ​​the laser beam passing through dimming aperture 3.2. The aperture of dimming aperture 3.2 is greater than or equal to the diameter of the laser beam split by beam splitter 2. The larger the cross-sectional area of ​​the laser beam passing through dimming aperture 3.2, the greater the actual cutting power of the laser; conversely, the smaller the cross-sectional area of ​​the laser beam passing through dimming aperture 3.2, the smaller the actual cutting power of the laser beam. Specifically, translation mechanism 3.4 drives adjustment component 3.1 to allow the laser beam to pass completely through dimming aperture 3.2 or partially block it, thus adjusting the cross-sectional area of ​​the laser beam passing through dimming aperture 3.2.

[0048] In this embodiment, an adjustable multi-path laser cutting device for an embroidery machine splits a single laser beam emitted by the laser generator 1 into two beams using a beam splitter 2. Each beam can cut the fabric at one cutting station, thus enabling the same laser generator 1 to simultaneously cut the fabric at two stations of the embroidery machine. This reduces the number of laser generators 1 required, saving costs, and allows for simultaneous cutting of fabric at multiple stations, ensuring production efficiency.

[0049] On the other hand, in practical applications, the translation mechanism 3.4 can drive the adjustment component 3.1 to move, thereby adjusting the cross-sectional area of ​​the laser passing through the dimming hole 3.2, and thus adjusting the actual cutting power of the laser (the larger the cross-sectional area of ​​the laser passing through the dimming hole 3.2, the greater the actual cutting power of the laser; conversely, the smaller the cross-sectional area of ​​the laser passing through the dimming hole 3.2, the smaller the actual cutting power of the laser), so as to ensure the accuracy and consistency of the actual cutting power of the laser at different cutting stations in the embroidery machine, effectively improve the cutting quality of the embroidery fabric, and solve the problem of the actual cutting power of the laser being too large or too small due to the output power error of the laser itself and the difference in the laser's optical path.

[0050] Furthermore, the actual cutting power of the laser can be adjusted by changing the cross-sectional area of ​​the laser passing through the dimming hole 3.2, thus adapting to the actual cutting needs of different fabrics and improving the versatility of the laser cutting equipment. At the same time, adjusting the cross-sectional area of ​​the laser passing through the dimming hole 3.2 is convenient, simple in structure, and low in manufacturing cost, which helps to save on production costs.

[0051] Specifically, such as Figure 1As shown, an adjustable multi-path laser cutting device for an embroidery machine further includes two focusing elements 4 and a laser path adjustment component 5. The laser generator 1, focusing elements 4, and laser path adjustment component 5 are all mounted on the frame of the embroidery machine. The laser generator 1, focusing elements 4, and laser path adjustment component 5 can each be mounted individually on the frame, or they can be first mounted on the same bracket, and then the laser generator 1, focusing elements 4, and laser path adjustment component 5 of the multi-path laser cutting device for an embroidery machine are mounted together on the frame via the bracket.

[0052] The laser path adjustment component 5 corresponds one-to-one with the focusing element 4. The laser path adjustment component 5 also corresponds one-to-one with the two laser beams split by the beam splitter 2. The laser path adjustment component 5 includes at least one reflector 5.1. For example, the laser path adjustment component 5 includes 2-5 reflectors 5.1; the specific number and installation position of the reflectors 5.1 are adjusted and determined according to the actual cutting station position. The two laser beams split from the beam splitter 2 are focused by the corresponding focusing element 4 after passing through the reflector 5.1 of the laser path adjustment component 5. In this way, the laser path can be adjusted by the reflector 5.1 of the laser path adjustment component 5, thereby adjusting the position of the focusing lens and the cutting part to meet different cutting needs.

[0053] The laser adjustment unit 3 corresponds one-to-one with the focusing element 4. The dimming aperture 3.2 of the laser adjustment unit 3 is arranged on the laser path between the beam splitter 2 and the corresponding focusing element 4. That is, the dimming aperture 3.2 of the laser adjustment unit 3 can be arranged at any position on the laser path between the beam splitter 2 and the corresponding focusing element 4.

[0054] In one example, such as Figure 4 As shown, the dimming aperture 3.2 of the laser adjustment unit 3 is close to the beam splitter 2. This facilitates the arrangement and actual installation of the laser adjustment unit 3.

[0055] In one embodiment of this example, such as Figure 4 As shown, laser generator 1 emits a laser beam from top to bottom through its laser emission port. Beam splitter 2 is located below the laser emission port of laser generator 1. Beam splitter 2 splits the laser beam emitted by laser generator 1 into two laser beams. One of the two laser beams emitted by beam splitter 2 is emitted horizontally, and the other is emitted vertically downwards.

[0056] It should be noted that the angles of the two laser beams split by beam splitter 2 can be adjusted according to actual needs. For example, one laser beam can be at an angle of 0-45 degrees to the horizontal plane, and the other laser beam can be at an angle of 60-120 degrees to the horizontal plane.

[0057] Furthermore, such as Figure 1 As shown, the laser path adjustment component 5 also includes an outer protective tube 5.2 distributed along the laser path. The two laser beams split by the beam splitter 2 are transmitted within the corresponding outer protective tube 5.2 of the laser path adjustment component 5. In this way, on the one hand, the outer protective tube 5.2 can ensure that the laser path is not blocked by foreign objects, and on the other hand, it can effectively prevent objects or personnel from coming into contact with the laser, thereby protecting the objects and operators.

[0058] Furthermore, such as Figure 4 As shown, an adjustable multi-path laser cutting device for an embroidery machine also includes a mounting bracket 6. The mounting bracket 6 is mounted on the housing of the laser generator 1 at the laser emission port. The beam splitter 2 is fixedly mounted on the mounting bracket 6. This facilitates the installation of the beam splitter 2.

[0059] Furthermore, such as Figure 4 As shown, the laser adjustment unit 3 also includes an adjustment support 3.3. A translation mechanism 3.4 is mounted on the adjustment support 3.3. In this embodiment, the adjustment support 3.3 is threadedly mounted on the adjustment support 3.3, and the adjustment member 3.1 is slidably mounted on the adjustment support 3.3. This facilitates the installation of the laser adjustment unit 3.

[0060] 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.
