Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a rotary adjustable laser cutting device for 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 no burrs, standardized dimensions, and minimal error, making it widely used in embroidery machines. Unlike conventional fabric cutting, embroidery machines often cut fabrics with two layers: a face fabric and a back fabric. Laser cutting only cuts the face fabric, not the back fabric. Therefore, the actual cutting power of the laser cutting device is critical. If the actual cutting power is too high, it's easy to cut too much into the back fabric; if the actual cutting power is too low, the face fabric may not be cut completely.

[0003] Currently, laser cutting devices used in embroidery machines generally include a focusing element (such as a focusing lens) and a laser path adjustment unit. The laser path adjustment unit includes several reflectors arranged sequentially along the laser path. The laser emitted by the laser is reflected by these reflectors 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 devices, due to manufacturing errors in the laser's output power and errors in the installation positions of the laser, focusing element, and reflectors in the laser path adjustment unit, the optical paths of the lasers in different laser cutting devices used in the same embroidery machine differ. 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] On the other hand, when the same laser can emit multiple laser beams (i.e., the same laser cutting device can emit multiple laser beams), and the fabric at different workstations is cut by each laser beam, since the power of each laser beam emitted by the same laser is the same, but the installation position of each reflector of the focusing element and the laser path adjustment unit corresponding to each laser beam is incorrect, the optical paths of each laser beam emitted by the same laser are different. This makes it difficult to adjust the actual cutting power of each laser beam emitted by the same laser to be consistent, and it is easy to have the problem that the actual laser cutting power is too high or too low.

[0005] For example, Chinese Patent Publication No. CN218426248U, entitled "A Rotation Adjustable Laser Cutter for an Embroidery Machine," also has the aforementioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a rotary adjustable laser cutting device for embroidery machines, which can adjust the actual laser cutting power to ensure the accuracy and consistency of the actual laser cutting power of the laser cutting device used in embroidery machines. This effectively solves the problem of the actual laser cutting power 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.

[0007] The technical solution of this utility model is:

[0008] A rotary adjustable laser cutting device for embroidery machines includes a laser and a rotary adjustment assembly. The rotary adjustment assembly includes a rotating component and an adjustment through-hole on the rotating component. The laser emitted by the laser passes through the adjustment through-hole, and the rotating component drives the adjustment through-hole to rotate, thereby adjusting the cross-sectional area of ​​the laser passing through the adjustment through-hole. Based on this, in practical applications of this rotary adjustable laser cutting device for embroidery machines, the rotating component can drive the adjustment through-hole to rotate, thereby adjusting the cross-sectional area of ​​the laser passing through the adjustment through-hole, and thus adjusting the actual laser cutting power (the larger the cross-sectional area of ​​the laser passing through the adjustment through-hole, the greater the actual laser cutting power; conversely, the smaller the cross-sectional area of ​​the laser passing through the adjustment through-hole, the smaller the actual laser cutting power). This ensures the accuracy and consistency of the actual laser cutting power among the various laser cutting devices used in the embroidery machine, thereby guaranteeing the cutting quality of the embroidery fabric and effectively solving the problem of excessively high or low actual laser cutting power caused by inherent errors in the laser's output power and differences in the laser's optical path.

[0009] On the other hand, in practical applications, the actual cutting power of the laser can be adjusted by changing the cross-sectional area of ​​the laser through the adjustment aperture, so as to adapt to the actual cutting needs of different fabrics and improve the versatility of the laser cutting equipment.

[0010] In addition, the rotating adjustment component of the rotating adjustment laser cutting equipment for embroidery machines proposed in this solution has a simple structure, is easy to adjust and operate, and has low manufacturing cost, which helps to save manufacturing costs.

[0011] Preferably, the rotation adjustment assembly also includes a drive motor, which drives the rotating component to rotate, thereby adjusting the cross-sectional area of ​​the laser passing through the adjustment through-hole. In this way, the drive motor can be used to drive the rotating component to rotate, thus automatically adjusting the cross-sectional area of ​​the laser passing through the adjustment through-hole, and consequently adjusting the actual laser cutting power.

[0012] Preferably, the rotation adjustment assembly also includes a mounting component, which is a screw threaded onto the mounting component. The adjustment through-hole extends radially through the screw. Thus, the cross-sectional area of ​​the laser passing through the adjustment through-hole can be manually adjusted by rotating the screw, thereby adjusting the actual laser cutting power. Furthermore, during screw rotation, not only can the adjustment through-hole be rotated, but it can also be moved axially along the screw, allowing for combined adjustment of the laser cross-sectional area through both rotation and axial movement.

[0013] Preferably, the rotation adjustment assembly also includes an elastic element. One end of the screw has a stop, and the elastic element is located between the stop and the mounting component. The elastic element provides a preload force to the screw to prevent it from loosening. Thus, after adjusting the orientation angle of the adjustment through-hole using the screw, the elastic element provides a preload force to the screw, preventing it from loosening and rotating, thereby ensuring the accuracy of the actual laser cutting power.

[0014] A preferred rotation adjustment assembly also includes a mounting component with a shaft hole. The rotating component is a guide rod rotatably mounted on the shaft hole, and the adjustment through-hole extends radially through the guide rod. Thus, by rotating the guide rod, the cross-sectional area of ​​the laser beam passing through the adjustment through-hole can be adjusted, thereby regulating the actual laser cutting power.

[0015] Preferably, the rotation adjustment assembly also includes an elastic element. The optical rod has two limiting members, the shaft hole is located between the two limiting members, and the elastic element is located between the mounting part and one of the limiting members. The other limiting member abuts against the surface of the mounting part under the action of the elastic element. Thus, after adjusting the orientation angle of the adjustment through hole, a preload force can be provided by the elastic element onto the optical rod, causing the other limiting member to abut against the surface of the mounting part, preventing the optical rod from loosening and rotating, thereby ensuring the accuracy of the actual laser cutting power.

[0016] Preferably, the laser includes at least two laser emission ports, each capable of emitting a laser beam. The rotation adjustment components correspond one-to-one with each laser emission port, and the laser beam emitted from each port passes through the adjustment vias of the corresponding rotation adjustment components. Based on this, the laser beams emitted from each laser emission port of the same laser can be adjusted using the corresponding rotation adjustment components, thereby ensuring the accuracy and consistency of the actual cutting power among the laser beams emitted by the same laser. This guarantees the cutting quality of the embroidery fabric and effectively solves the problem that, despite the identical power of the laser beams emitted by the same laser, errors in the installation positions of the focusing elements and reflectors in the laser path adjustment unit cause differences in the optical paths of the laser beams emitted by the same laser, making it difficult to adjust the actual cutting power of the laser beams to be consistent, and easily leading to problems such as the actual cutting power being too high or too low.

[0017] As a preferred option, it also includes:

[0018] Each focusing element corresponds one-to-one with a laser emission port;

[0019] A laser path adjustment unit corresponds one-to-one with a laser outlet. The laser path adjustment unit includes at least one reflector. The reflector of the laser path adjustment unit reflects the laser emitted from the laser outlet to the corresponding focusing element for focusing.

[0020] The adjustment through-hole of the rotation adjustment assembly is arranged on the laser path between the corresponding laser emission port and the corresponding focusing element. In this way, the laser path can be adjusted by the reflector of the laser path adjustment unit, thereby adjusting the position of the fabric cutting part to adapt to the actual cutting needs.

[0021] Preferably, the rotation adjustment component is located near the laser emission port. This facilitates the arrangement and actual installation of the rotation adjustment component.

[0022] Preferably, the laser also includes a columnar generator body, with the laser emission port disposed on the generator body, which is vertically or horizontally distributed.

[0023] Preferably, the system also includes a focusing element and a laser path adjustment unit. The laser path adjustment unit includes at least one reflector, which reflects the laser emitted by the laser to the corresponding focusing element for focusing. The adjustment via is arranged on the laser path between the laser and the focusing element. Thus, the laser path can be adjusted using the reflector of the laser path adjustment unit, thereby adjusting the position of the fabric cutting area to suit actual cutting needs.

[0024] The beneficial effects of this utility model are as follows: In practical applications, the cross-sectional area of ​​the laser passing through the adjustment hole can be adjusted by rotating the rotating component, thereby adjusting the actual laser cutting power (the larger the cross-sectional area of ​​the laser passing through the adjustment hole, the greater the actual laser cutting power; conversely, the smaller the cross-sectional area of ​​the laser passing through the adjustment hole, the smaller the actual laser cutting power). This ensures the accuracy and consistency of the actual laser cutting power, which can guarantee the accuracy and consistency of the actual laser cutting power between various laser cutting devices used in the embroidery machine, as well as the accuracy and consistency of the actual laser cutting power between different laser beams emitted by the same laser in the same laser cutting device, thus ensuring the cutting quality of the embroidery fabric.

[0033] Rotation adjustment assembly 2, rotating component 2.1, adjustment through hole 2.2, mounting component 2.3, drive motor 2.4, limiting component 2.5, elastic element 2.6, stop block 2.7;

[0035] Focusing element 4. Detailed Implementation

[0036] Specific Implementation Example 1, such as Figures 1-6 As shown, a rotary adjustable laser cutting device for embroidery machines includes a laser 1 and a rotary adjustment assembly 2. The rotary adjustment assembly 2 includes a rotatable component 2.1 and an adjustment through-hole 2.2 disposed on the rotatable component 2.1. The laser emitted by the laser 1 passes through the adjustment through-hole 2.2. The rotatable component 2.1 drives the adjustment through-hole 2.2 to rotate, thereby adjusting the cross-sectional area of ​​the laser passing through the adjustment through-hole 2.2.

[0037] In practical application, the rotary adjustable laser cutting device for embroidery machines in this embodiment can rotate the adjusting through-hole 2.2 via the rotating component 2.1 to adjust the cross-sectional area of ​​the laser passing through the adjusting through-hole 2.2, thereby adjusting the actual laser cutting power (the larger the cross-sectional area of ​​the laser passing through the adjusting through-hole 2.2, the greater the actual laser cutting power; conversely, the smaller the cross-sectional area of ​​the laser passing through the adjusting through-hole 2.2, the smaller the actual laser cutting power). This eliminates the deviation in actual laser cutting power caused by manufacturing errors in the laser's output power and errors in the installation positions of the laser, focusing element 4, and the reflectors 3.1 of the laser path adjustment unit 3. This ensures the accuracy and consistency of the actual laser cutting power among the various laser cutting devices used in the embroidery machine, thereby guaranteeing the cutting quality of the embroidery fabric and effectively solving the problem of excessively high or low actual laser cutting power caused by errors in the laser's output power and differences in the laser's optical path.

[0038] On the other hand, in practical applications, the actual cutting power of the laser can be adjusted by changing the cross-sectional area of ​​the laser through the adjustment aperture 2.2 to adapt to the actual cutting needs of different fabrics and improve the versatility of the laser cutting equipment.

[0039] In addition, the rotation adjustment component 2 of the rotation adjustment laser cutting equipment for embroidery machines in this embodiment has a simple structure, is easy to adjust and operate, and has low manufacturing cost, which helps to save manufacturing costs.

[0040] Specifically, such as Figures 1-3As shown, a rotary adjustable laser cutting device for embroidery machines further includes a focusing element 4 and a laser path adjustment unit 3. The laser 1 includes a laser emission port 1.1, from which the laser light emitted from the laser 1 is emitted. The focusing element 4 is a focusing lens. The laser path adjustment unit 3 includes at least one reflector 3.1; for example, the laser path adjustment unit 3 includes 2-6 reflectors 3.1. The reflectors 3.1 of the laser path adjustment unit 3 reflect the laser light emitted from the laser 1 to the corresponding focusing element 4 for focusing. Specifically, the laser light emitted from the laser 1 enters the focusing element 4 for focusing after being reflected by each reflector 3.1 of the laser path adjustment unit 3. Thus, the laser path can be adjusted by the reflectors 3.1 of the laser path adjustment unit 3, thereby adjusting the position of the cutting area on the fabric to adapt to actual cutting needs.

[0041] The adjustment via 2.2 of the rotation adjustment assembly 2 is arranged on the laser path between the laser and the focusing element 4. The adjustment via 2.2 of the rotation adjustment assembly 2 can be arranged at any position on the laser path between the laser and the focusing element 4.

[0042] In one example, the rotation adjustment component 2 is positioned close to the laser emission port 1.1. This facilitates the arrangement and actual installation of the rotation adjustment component 2.

[0043] Furthermore, such as Figures 1-3 As shown, the laser path adjustment unit 3 also includes an outer protective tube 3.2 distributed along the laser path, and the laser emitted by the laser is transmitted within the outer protective tube 3.2 of the laser path adjustment unit 3. In this way, on the one hand, the outer protective tube 3.2 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.

[0044] The rotating component 2.1 of the rotation adjustment assembly 2 in this embodiment can be manually driven or electrically driven.

[0045] In one embodiment of this example, such as Figure 4 As shown, the rotation adjustment assembly 2 also includes a drive motor 2.4, which drives the rotating component 2.1 to rotate, thereby adjusting the cross-sectional area of ​​the laser passing through the adjustment aperture 2.2. Thus, by driving the rotating component 2.1 to rotate via the drive motor 2.4, the cross-sectional area of ​​the laser passing through the adjustment aperture 2.2 can be automatically adjusted, thereby regulating the actual laser cutting power.

[0046] Furthermore, such as Figures 4-6 As shown, the rotation adjustment assembly 2 also includes a mounting member 2.3. The mounting member 2.3 can be a bracket or a support. The rotating member 2.1 is rotatably mounted on the mounting member 2.3. Although Figures 4-6The rotation axis of the rotating component 2.1 shown is horizontally distributed, but in actual applications, the rotation axis of the rotating component 2.1 is not limited to a horizontal distribution. The rotation axis of the rotating component 2.1 can be set to a vertical or inclined distribution as needed.

[0047] In this embodiment, as Figures 1-4 As shown, mounting component 2.3 is a mounting sleeve. Rotating component 2.1 is rotatably mounted on the mounting sleeve, with a portion of rotating component 2.1 located inside the mounting sleeve. Adjustment through hole 2.2 is also located inside the mounting sleeve. The mounting sleeve can be positioned between the outer protective tube 3.2 and the laser exit port 1.1, or it can be positioned at any point on the outer protective tube 3.2. The mounting sleeve and the outer protective tube 3.2 can be manufactured separately and then connected together; alternatively, the mounting sleeve can be directly formed from a portion of the outer protective tube 3.2.

[0048] In one embodiment of this example, such as Figure 4 , Figure 5 As shown, mounting component 2.3 has a shaft hole. Rotating component 2.1 is composed of a guide rod. The guide rod is rotatably mounted on the shaft hole. Adjustment through hole 2.2 passes through the guide rod radially. Thus, by rotating the guide rod, the cross-sectional area of ​​the laser passing through adjustment through hole 2.2 can be adjusted, thereby adjusting the actual laser cutting power.

[0049] In one example, such as Figure 4 As shown, the rotation adjustment assembly 2 also includes a drive motor 2.4, which drives the guide rod to rotate. The guide rod and the output shaft of the drive motor 2.4 are coaxial or parallel. For example, the output shaft of the drive motor 2.4 is directly connected to the guide rod, and the guide rod and the output shaft of the drive motor 2.4 are coaxial; or the output shaft of the drive motor is connected to the guide rod through a gear transmission mechanism or a pulley transmission mechanism, and the drive motor drives the guide rod to rotate through the gear transmission mechanism or the pulley transmission mechanism.

[0050] In this example, a drive motor 2.4 is used to drive the optical rod to rotate, thereby automatically adjusting the cross-sectional area of ​​the laser passing through the adjustment aperture 2.2, and thus adjusting the actual cutting power of the laser.

[0051] In another example, the rotation adjustment assembly 2 also includes a drive motor 2.4, which drives the optical rod to rotate. The optical rod is perpendicular to the output shaft of the drive motor 2.4. In this example, the optical rod can also be composed of a rotating plate or a rotating block. In this example, the drive motor 2.4 is used to drive the optical rod to rotate, thereby automatically adjusting the cross-sectional area of ​​the laser passing through the adjustment aperture 2.2, and thus adjusting the actual cutting power of the laser.

[0052] In the third example, such as Figure 5As shown, the rotation adjustment assembly 2 also includes an elastic element 2.6, which is a spring, an elastic rubber sleeve, or a disc spring. The optical rod has two limiting members 2.5. The shaft hole is located between the two limiting members 2.5. In this example, the elastic element 2.6 is located outside the mounting sleeve. The mounting sleeve is located between the two limiting members 2.5. The elastic element 2.6 is sleeved on the optical rod. The elastic element 2.6 is located between the mounting member 2.3 and one of the limiting members 2.5, and the other limiting member 2.5 abuts against the surface of the mounting member 2.3 under the action of the elastic element 2.6. In this example, the optical rod is rotated manually. After adjusting the orientation angle of the adjustment through hole 2.2, a preload force can be provided by the elastic element 2.6 to act on the optical rod, causing the other limiting member 2.5 to abut against the surface of the mounting member 2.3, preventing the optical rod from loosening and rotating, thereby ensuring the accuracy of the actual laser cutting power.

[0053] In the second embodiment of this example, as follows: Figure 6 As shown, the rotating component 2.1 is composed of a screw, which is threadedly connected to the mounting component 2.3. An adjustment through-hole 2.2 passes radially through the screw. Thus, the cross-sectional area of ​​the laser passing through the adjustment through-hole 2.2 can be manually adjusted by rotating the screw, thereby adjusting the actual laser cutting power. Furthermore, during screw rotation, not only can the adjustment through-hole 2.2 be rotated, but it can also be moved axially along the screw, thereby adjusting the cross-sectional area of ​​the laser passing through the adjustment through-hole 2.2 through both rotation and axial movement.

[0054] Furthermore, such as Figure 6 As shown, the rotation adjustment assembly 2 also includes an elastic element 2.6. The elastic element 2.6 is a spring, an elastic rubber sleeve, or a disc spring. A stop 2.7 is provided at one end of the screw. In this embodiment, both the stop 2.7 and the elastic element 2.6 are located outside the mounting sleeve. The elastic element 2.6 is sleeved on the screw. The elastic element 2.6 is located between the stop 2.7 and the mounting component 2.3. The elastic element 2.6 provides a preload force acting on the screw to prevent it from loosening. Thus, after adjusting the orientation angle of the adjustment through-hole 2.2 using the screw, the elastic element 2.6 provides a preload force acting on the screw to prevent it from loosening and rotating, thereby ensuring the accuracy of the actual laser cutting power.

[0055] Specific embodiment two: The remaining structure of this embodiment is the same as that of specific embodiment one, except that...

[0056] like Figure 1 , Figure 2As shown, the laser 1 includes at least two laser emission ports 1.1. For example, the laser includes two, three, or four laser emission ports 1.1. Each laser emission port 1.1 can emit a laser beam. When the laser is operating, each laser emission port 1.1 emits a laser beam simultaneously. The laser emission ports 1.1 can be arranged on the same side of the laser, or they can be arranged on both sides of the laser as needed.

[0057] The focusing element 4 corresponds one-to-one with the laser exit port 1.1. All focusing elements 4 are located at the same height.

[0058] The laser path adjustment unit 3 corresponds one-to-one with the laser emission port 1.1. The laser path adjustment unit 3 also corresponds one-to-one with the focusing element 4. The reflector 3.1 of the laser path adjustment unit 3 reflects the laser beam emitted from the corresponding laser emission port 1.1 to the corresponding focusing lens for focusing.

[0059] The rotation adjustment component 2 corresponds one-to-one with the laser emission port 1.1. The laser emitted from the laser emission port 1.1 passes through the adjustment through hole 2.2 of the corresponding rotation adjustment component 2. The adjustment through hole 2.2 of the rotation adjustment component 2 is arranged on the laser path between the corresponding laser emission port 1.1 and the corresponding focusing element 4.

[0060] Based on this, the lasers emitted from each laser outlet 1.1 of the same laser 1 can be adjusted by the corresponding rotation adjustment component 2, thereby ensuring the accuracy and consistency of the actual cutting power of each laser beam emitted by the same laser, thus ensuring the cutting quality of the embroidery machine fabric. This effectively solves the problem that because the power of each laser beam emitted by the same laser is the same, but the installation position of each focusing element 4 and each reflector 3.1 of the laser path adjustment unit 3 for each laser beam is incorrect, the optical paths of each laser beam emitted by the same laser are different, which makes it difficult to adjust the actual cutting power of each laser beam emitted by the same laser to be consistent, and the problem of the actual laser cutting power being too high or too low is easily caused.

[0061] The laser also includes a columnar generator body 1.2. A laser emission port 1.1 is disposed on the generator body 1.2.

[0062] In one embodiment of this example, such as Figure 1 As shown, the generator body 1.2 is vertically distributed. In this embodiment, the vertical distribution of the generator body 1.2 means that the length of the columnar generator body 1.2 is vertically distributed. In this way, the space in the vertical direction can be used to arrange the laser, effectively reducing the space occupied by the laser in the horizontal direction.

[0063] Furthermore, a portion of the laser emission ports 1.1 are located at the bottom of the generator body 1.2 and emit laser light downwards, while the other portion are located at the top of the generator body 1.2 and emit laser light upwards. In this embodiment, as... Figure 1 , Figure 2 As shown, the laser emitter has two laser emission ports 1.1. One laser emission port 1.1 is located at the bottom of the generator body 1.2 and emits laser downwards, while the other laser emission port 1.1 is located at the top of the generator body 1.2 and emits laser upwards.

[0064] In another embodiment of this example, such as Figure 2 As shown, the generator body 1.2 is horizontally distributed. In this embodiment, the horizontal distribution of the generator body 1.2 means that the length of the columnar generator body 1.2 is horizontally distributed. In this way, the space in the horizontal direction can be used to arrange the laser, effectively reducing the space occupied by the laser in the vertical direction.

[0065] Furthermore, such as Figure 2 As shown, some of the laser emission ports 1.1 are located at the left end of the generator body 1.2, while the other portion are located at the right end. The laser emission ports 1.1 located at the left end of the generator body 1.2 emit laser light towards the left side of the generator body 1.2, and the laser emission ports 1.1 located at the right end of the generator body 1.2 emit laser light towards the right side of the generator body 1.2. This arrangement of the laser emission ports 1.1 and the direction of laser emission from them facilitates the adaptation of the laser cutting device to the actual cutting needs of the embroidery machine.

[0066] In this embodiment, the columnar generator body 1.2 is horizontally distributed along the left-right direction of the embroidery machine. There are two laser emission ports 1.1 of the laser, one of which is located at the left end of the generator body 1.2, and the other of which is located at the left end of the generator body 1.2.

[0067] In this specific embodiment, the remaining structure is the same as in the specific embodiment, except that...

[0068] like Figure 3 As shown, laser 1 has a laser emission port 1.1, which can emit a laser beam. The same laser 1 can emit a single laser beam.

[0069] The laser also includes a columnar generator body 1.2. A laser emission port 1.1 is disposed on the generator body 1.2.

[0070] In one embodiment of this example, such as Figure 3 As shown, the generator body 1.2 is vertically arranged. In this embodiment, the vertical arrangement of the generator body 1.2 means that the length of the columnar generator body 1.2 is vertically oriented. This allows the space in the vertical direction to be utilized to arrange the laser, effectively reducing the space occupied by the laser in the horizontal direction. The laser emission port 1.1 is located at the bottom end of the generator body 1.2 and emits laser light downwards.

[0071] In another embodiment of this invention, the generator body 1.2 is horizontally distributed. In this embodiment, the horizontal distribution of the generator body 1.2 means that the length of the columnar generator body 1.2 is horizontally distributed. This allows for the use of horizontal space to arrange the laser, effectively reducing the space occupied by the laser in the vertical direction. The laser emission port 1.1 is located at the left or right end of the generator body 1.2.

[0072] 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.
