Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting devices, and particularly relates to a shirt production device based on laser cutting. Background Art

[0002] Laser cutting is a process that uses laser technology to precisely cut textiles, with the significant advantages of high precision, high efficiency, and high automation. During the shirt production process, laser cutting is often used for the preliminary cutting of fabrics. However, when the existing laser cutting device cuts fabrics, the cutting edge of the fabric will deform due to excessive heat, resulting in the phenomenon of the cutting edge warping. This problem is particularly prominent when cutting thicker shirt fabrics, especially fleece-lined shirt fabrics. Since the heat generated during the laser cutting process is difficult to dissipate in a timely manner, and when cutting thick fabrics, the heat generated during cutting will increase significantly, resulting in a more serious phenomenon of the cutting edge deforming and warping. The warped position of the fabric will exert a pulling force on the cut position of the fabric, causing the cut position of the fabric to become uneven, thereby changing the cut position of the fabric. The existing device can only flatten the whole fabric during the cutting process and cannot flatten and trim the warped position of the fabric, resulting in a reduction in the accuracy of laser cutting and the quality of fabric cutting. Summary of the Invention

[0003] The present invention provides a shirt production device based on laser cutting to solve the problem that the fabric edge is prone to warping during the cutting process, which affects the fabric cutting quality.

[0004] The technical solution of the present invention is as follows: A shirt production device based on laser cutting includes a cutting bed, on which a conveyor belt and a control terminal are arranged. A first sliding frame is fixedly connected to the cutting bed. A second sliding frame is arranged on the first sliding frame. A sliding block is slidably connected to the second sliding frame. The sliding block is fixedly connected with a laser knife, which is used for cutting the fabric. The laser knife is provided with a rotating sleeve, and a lifting plate is slidably connected to the rotating sleeve. The lifting plate is slidably connected with symmetrically distributed L-shaped rods. One side of the L-shaped rod away from the lifting plate is provided with a pressing wheel through a one-way rotating shaft. The pressing wheel is used for pressing the warped position of the fabric to make the fabric at the cutting position flat. A power component is arranged on the laser knife, and the power component is used for driving the pressing wheel to move downward so that the pressing wheel presses the warped position of the fabric at the cutting position.

[0005] As a preference, the power assembly includes a support plate which is fixedly connected to the sliding block. The support plate is fixedly connected with an electric push rod, and a pressure sensor is arranged on the electric push rod. An adjusting pipe is arranged at the telescopic end of the electric push rod, and the adjusting pipe is used to drive the lifting plate to move. The rotating sleeve is fixedly connected with a guide frame which is slidably connected with the L-shaped rod. A first spring is fixedly connected between the guide frame and the lifting plate. A guiding assembly is arranged on the guide frame, and the guiding assembly is used to drive the symmetrically distributed L-shaped rods to gather towards each other, so that the squeezing wheels stretch the warped fabric.

[0006] As a preference, the guiding assembly includes symmetrically distributed convex rings which are respectively fixedly connected to the middle parts of adjacent L-shaped rods. Symmetrically distributed guiding grooves are arranged in the guide frame, and the convex rings are slidably located in the adjacent guiding grooves.

[0007] As a preference, the distance between the symmetrically distributed guiding grooves decreases as the horizontal distance between them and the laser knife increases.

[0008] As a preference, circumferentially distributed guiding strips are arranged on the squeezing wheels, and the guiding strips are used to increase the friction between the squeezing wheels and the fabric.

[0009] As a preference, a rotating assembly is further included. The rotating assembly is arranged on the support plate and is used to drive the rotating sleeve to rotate. The rotating assembly includes a motor which is fixedly connected to the support plate. The rotating sleeve is rotatably connected with the laser knife. The output shaft of the motor is rotatably connected to the support plate. The motor is electrically connected to the control terminal of the cutting bed. A gear is fixedly connected to the output shaft of the motor. An external gear ring is fixedly connected to the rotating sleeve. The external gear ring is rotatably connected with the laser knife and meshes with the gear. A fixing assembly is arranged on the rotating sleeve, and the fixing assembly is used to squeeze and fix the warped position of the fabric when adjusting the position of the squeezing wheels.

[0010] As a preference, the fixing assembly includes a fixing ring which is rotatably and slidably connected to the rotating sleeve. An elastic member is arranged between the fixing ring and the rotating sleeve. The fixing ring is fixedly connected with a fixing frame which is used to fix the warped position of the fabric. A transmission assembly is arranged on the telescopic end of the electric push rod, and the transmission assembly is used to drive the fixing frame to move when the lifting plate rotates and fix the warped position of the fabric.

[0011] As a preference, the transmission assembly includes an extrusion rod, which is fixedly connected to the telescopic end of the electric push rod. The telescopic end of the electric push rod and the extrusion rod are both slidably connected to the adjustment tube. A second spring is fixedly connected between the telescopic end of the electric push rod and the adjustment tube. The extrusion rod is used to push the fixed ring downward. A separation assembly is arranged on the rotating sleeve, and the separation assembly is used to drive the lifting plate upward to separate the extrusion wheel from the fabric.

[0012] As a preference, the fixed ring is provided with circumferentially distributed convex strips, which are used to increase the contact area between the fixed ring and the extrusion rod.

[0013] As a preference, the separation assembly includes an adjustment ring, which is slidably connected to the rotating sleeve. A pull rope is fixedly connected between the adjustment ring and the upper side of the lifting plate. The pull rope passes through the rotating sleeve, and the adjustment ring is located on the moving path of the fixed ring.

[0014] The beneficial effects are as follows: 1. During the process of cutting the fabric, the L-shaped rod drives the extrusion wheel to move downward to squeeze the warped position of the fabric, reducing the pulling force of the warped position of the fabric on the cutting position of the fabric, reducing the deformation amount at the cutting position of the fabric, and thus improving the cutting accuracy of the fabric.

[0015] 2. During the process of squeezing the fabric downward, the convex ring is guided through the guide groove, so that the extrusion wheel pulls the fabric away from the laser knife, making the cutting position of the fabric smoother, and thus further improving the cutting accuracy of the device.

[0016] 3. When it is necessary to adjust the position of the extrusion wheel, the cutting edge is fixed by the fixing frame, and the extrusion wheel is lifted upward to separate the extrusion wheel from the fabric, ensuring that during the movement of the extrusion wheel, the warped position of the fabric will not shrink and change, and thus ensuring the fixing effect on the cutting position of the fabric.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0028] A shirt production device based on laser cutting, such as Figures 1-6 As shown, it includes a cutting bed 1, on which a conveyor belt and a control terminal are arranged, a first sliding frame 2 is fixedly connected to the cutting bed 1, a second sliding frame 3 is arranged on the first sliding frame 2, a sliding block 4 is slidably connected to the second sliding frame 3, a laser knife 5 is fixedly connected to the sliding block 4, the laser knife 5 is used for cutting cloth, the laser knife 5 is provided with a rotating sleeve 6, the rotating sleeve 6 is slidably connected to a lifting plate 7, the lifting plate 7 is slidably connected to a symmetrically distributed L-shaped rod 8, a squeezing wheel 9 is arranged on the side of the L-shaped rod 8 away from the lifting plate 7 through a one-way rotating shaft, the squeezing wheel 9 is used for squeezing the raised position of the cloth, so that the cloth at the cutting position is in a flat state, and a power component is arranged on the laser knife 5, the power component is used to drive the squeezing wheel 9 to move downward, so that the squeezing wheel 9 squeezes the raised position of the cloth at the cutting position.

[0029] The above solution provides a way to press and flatten the warped position of the fabric near the cutting position during the process of cutting the fabric, reducing the influence of the warped position on the cutting position; the conveyor belt of the cutting table 1 is used to convey the fabric forward to achieve continuous production of the fabric. The control terminal of the cutting table 1 is electrically connected to the electrical components below and is used to control the start and stop times of the electrical components below. The first sliding frame 2 and the second sliding frame 3 are both existing electric slide rails, and their specific structures will not be elaborated too much. The first sliding frame 2 and the second sliding frame 3 jointly drive the sliding block 4 to move in the front-back direction and the left-right direction. The laser knife 5 is an existing device, and its internal structure and usage method will not be elaborated too much. In this embodiment, the laser knife 5 is fixedly connected to the rotating sleeve 6. The number of L-shaped rods 8 on the lifting plate 7 is two, and the number of L-shaped rods 8 can be adjusted according to the actual situation. A vision sensor is provided on the laser knife 5, which is not shown in the figure. This vision sensor is used to detect whether the edge of the cut fabric is warped. The pressing wheel 9 is used to press down the warped position near the cutting position of the fabric. Taking the Figure 1 direction as an example, under the action of the one-way rotating shaft, the pressing wheel 9 rotates when moving backward and does not rotate when moving forward.

[0030] Furthermore, as Figures 3-9 shown, the power assembly includes a support plate 10. The support plate 10 is fixedly connected to the sliding block 4. The support plate 10 is fixedly connected with an electric push rod 11. A pressure sensor is provided on the electric push rod 11. The telescopic end of the electric push rod 11 is provided with an adjustment tube 12. The adjustment tube 12 is used to drive the lifting plate 7 to move. The rotating sleeve 6 is fixedly connected with a guide frame 13. The guide frame 13 is slidably connected with the L-shaped rod 8. A first spring 14 is fixedly connected between the guide frame 13 and the lifting plate 7. A guide assembly is provided on the guide frame 13. The guide assembly is used to drive the symmetrically distributed L-shaped rods 8 to gather together, so that the pressing wheel 9 stretches the warped fabric.

[0031] In the above solution, the support plate 10 is located above the rotating sleeve 6. The pressure sensor on the electric push rod 11 is used to detect the reverse force of the fabric on the pressing wheel 9. When the fabric is no longer warped, the reverse force of the fabric on the pressing wheel 9 decreases. After the reverse force received by the pressing wheel 9 is less than the specified value (this specified value is the pressure when the pressing wheel 9 presses the fabric flat, and the specified value can be adjusted according to the actual situation), the telescopic end of the electric push rod 11 drives the adjustment tube 12 to move upward and reset. The pressure sensor is not shown in the figure. In this embodiment, the telescopic end of the electric push rod 11 is fixedly connected to the adjustment tube 12 and is used to directly drive the adjustment tube 12 to move downward to press the lifting plate 7. The first spring 14 is used to push the lifting plate 7 to move upward and reset.

[0032] Furthermore, as Figures 4-6 and Figure 8As shown in the figure, the guiding component includes symmetrically distributed convex rings 16, and the symmetrically distributed convex rings 16 are respectively fixedly connected to the middle parts of adjacent L-shaped rods 8. Symmetrically distributed guiding grooves 15 are arranged in the guiding frame 13, and the convex rings 16 are located and slide in the adjacent guiding grooves 15.

[0033] Further, as Figure 4 shown, the distance between the symmetrically distributed guiding grooves 15 decreases as the horizontal distance between them and the laser knife 5 increases.

[0034] Further, as Figure 4 and Figure 5 shown, circumferentially distributed guiding strips 17 are arranged on the pressing wheel 9, and the guiding strips 17 are used to increase the friction between the pressing wheel 9 and the fabric.

[0035] In the above solution, there is a way to drive the two pressing wheels 9 to move towards each other and away from the laser knife 5 during the process of driving the pressing wheel 9 to move downward to press the warped position of the fabric, so as to stretch the warped position of the fabric. Two through grooves are arranged on the guiding frame 13, and the two L-shaped rods 8 are respectively located and slide in the adjacent through grooves, and the distance between the two through grooves gradually decreases from the rear part to the front part. The maximum diameter of the convex ring 16 is greater than the width of the through groove on the guiding frame 13. The guiding groove 15 is composed of a vertical groove and an inclined groove. The vertical groove of the guiding groove 15 is used to guide the convex ring 16 to move vertically downward, and the inclined groove of the guiding groove 15 is used to guide the two convex rings 16 to move forward and make the two convex rings 16 approach each other during the forward movement. The shape of the guiding groove 15 can be adjusted according to the actual usage situation.

[0036] Workflow: When cutting shirt fabric (hereinafter referred to as fabric), the staff spreads the fabric flat on the conveyor belt of the cutting table 1, and then starts the conveyor belt through the control terminal. The conveyor belt drives the fabric to move forward (the start and stop of the following electrical components are all completed through the control terminal), until the front part of the fabric moves below the laser knife 5 and then the conveyor belt stops. The initial position of the laser knife 5 refers to Figure 1 , at this time, the staff sets the moving path of the first sliding frame 2 and the second sliding frame 3 to drive the sliding block 4 through the control terminal, so that the sliding block 4 drives the laser knife 5 to cut the fabric along the specified path. After the moving path of the sliding block 4 is set, the staff starts the first sliding frame 2, the second sliding frame 3, the laser knife 5, the vision sensor and the pressure sensor. The laser knife 5 cuts the fabric. During this process, the laser knife 5 drives the parts on it to move together through the rotating sleeve 6. After cutting this section of the fabric, the staff collects the cut fabric, and then starts the conveyor belt again and adjusts the position of the fabric to continue cutting.

[0037] During the above process of cutting the fabric, when the vision sensor on the laser knife 5 detects that there is a warp at the rear edge of the cut fabric, the control terminal activates the electric push rod 11. Taking the example of the sliding block 4 driving the laser knife 5 to move backward to cut the fabric, the telescopic end of the electric push rod 11 drives the adjusting pipe 12 to move downward. When the adjusting pipe 12 contacts the lifting plate 7, the adjusting pipe 12 presses the lifting plate 7 downward, causing the lifting plate 7 to drive the two L-shaped rods 8 to move downward and compress the first spring 14. The pressure received by the pressure sensor on the electric push rod 11 increases. The L-shaped rod 8 drives the convex ring 16 on it to move downward along the vertical groove of the guide groove 15. At the same time, the L-shaped rod 8 drives the pressing wheel 9 to move downward and approach the fabric. During this process, when the pressing wheel 9 contacts the warped position of the fabric, the pressing wheel 9 presses the warped position of the fabric downward, reducing the influence of the warped fabric on the cutting position of the fabric. At this time, the pressure received by the pressure sensor on the electric push rod 11 continues to increase, and the increase amplitude of the measured value on the pressure sensor at this time is greater than the measured value increase amplitude when the pressing wheel 9 is not in contact with the fabric, until the convex ring 16 moves to the lower end of the vertical groove of the guide groove 15, and the convex ring 16 enters the inclined groove of the guide groove 15. At this time, the fabric is not flattened.

[0038] After the above convex ring 16 enters the inclined groove of the guide groove 15, taking the moving direction of the left L-shaped rod 8 and its components as a reference, under the guidance of the inclined groove of the guide groove 15, the pressing wheel 9 continues to move downward to press the fabric. The L-shaped rod 8 drives the pressing wheel 9 to move right frontward relative to the laser knife 5. The pressing wheel 9 drives the adjacent area of the fabric to move right frontward. At this time, the pressing wheel 9 does not rotate. The pressing wheel 9 pulls the warped position of the fabric through the friction force between the guide strip 17 and the fabric, so that the fabric becomes flatter, further improving the cutting accuracy. Until the convex ring 16 moves to the lower end of the inclined part of the guide groove 15, the electric push rod 11 is turned off, the L-shaped rod 8 stops moving, the pressing wheel 9 stops moving downward and flattens the fabric, and the value detected by the pressure sensor on the electric push rod 11 no longer increases.

[0039] After the above pressing wheel 9 stops moving downward, the laser knife 5 drives the rotating sleeve 6 to continue to move synchronously. The rotating sleeve 6 drives the L-shaped rod 8 to move together through the lifting plate 7. The L-shaped rod 8 drives the pressing wheel 9 to move together with the laser knife 5.

[0040] During the process of the extrusion wheel 9 extruding the fabric, when the extrusion pressure detected by the pressure sensor on the electric push rod 11 decreases, that is, the degree of the fabric warping decreases. Until the value detected by the pressure sensor is less than the specified value, the electric push rod 11 starts. The telescopic end of the electric push rod 11 drives the adjusting pipe 12 to move upward and reset. The first spring 14 pushes the lifting plate 7 to move upward and reset. The lifting plate 7 drives the two L-shaped rods 8 to move upward, so that the convex ring 16 drives the L-shaped rod 8 to move reversely along the guiding groove 15 and reset. The extrusion wheel 9 is separated from the fabric. Until the telescopic end of the electric push rod 11 is completely retracted, the device is reset. After that, when the vision detector detects that the fabric warps again, the extrusion wheel 9 repeats the above process to extrude and stretch the fabric. When the fabric cutting is completed, the first sliding frame 2 and the second sliding frame 3 drive the sliding block 4 and its components on it to reset.

[0041] Further, as Figures 4-6 and Figure 9 shown, it further includes a rotating assembly. The rotating assembly is arranged on the support plate 10. The rotating assembly is used to drive the rotating sleeve 6 to rotate. The rotating assembly includes a motor 18. The motor 18 is fixedly connected to the support plate 10. The rotating sleeve 6 is rotatably connected to the laser knife 5. The output shaft of the motor 18 is rotatably connected to the support plate 10. The motor 18 is electrically connected to the control terminal of the cutting bed 1. A gear 19 is fixedly connected to the output shaft of the motor 18. An external toothed ring 20 is fixedly connected to the rotating sleeve 6. The external toothed ring 20 is rotatably connected to the laser knife 5. The external toothed ring 20 meshes with the gear 19. A fixing assembly is arranged on the rotating sleeve 6. The fixing assembly is used to squeeze and fix the warped position of the fabric when adjusting the position of the extrusion wheel 9.

[0042] The above solution provides a way to drive the lifting plate 7 to rotate so that the extrusion wheel 9 is always behind the moving direction of the laser knife 5. A speed reducer can be arranged between the output shaft of the motor 18 and the gear 19 to slow down the rotation speed output by the output shaft of the motor 18 and improve the rotation accuracy of the rotating sleeve 6. The number of teeth of the gear 19 is less than the number of teeth of the external toothed ring 20. In this embodiment, the rotating sleeve 6 is rotatably connected to the laser knife 5.

[0043] Further, as Figures 4-9 shown, the fixing assembly includes a fixing ring 21. The fixing ring 21 is rotatably and slidably connected to the rotating sleeve 6. An elastic member 211 is arranged between the fixing ring 21 and the rotating sleeve 6. A fixing frame 22 is fixedly connected to the fixing ring 21. The fixing frame 22 is used to fix the warped position of the fabric. A transmission assembly is arranged on the telescopic end of the electric push rod 11. The transmission assembly is used to drive the fixing frame 22 to move when the lifting plate 7 rotates and fix the warped position of the fabric.

[0044] The above solution provides a way to fix the cutting edge of the fabric during the rotation of the rotating sleeve 6 driving the pressing wheel 9; the fixing ring 21 is located below the guiding frame 13, and the elastic member 211 is used to drive the fixing ring 21 to rotate and reset. In this embodiment, the elastic member 211 is a torsion spring that can be slightly compressed, used to enable the fixing ring 21 to move downward relative to the rotating sleeve 6. The fixing frame 22 is a T-shaped frame, and the fixing frame 22 is used to simultaneously press both sides of the fabric cutting position.

[0045] Further, as Figure 9 shown, the transmission assembly includes a pressing rod 23. The pressing rod 23 is fixedly connected to the telescopic end of the electric push rod 11. The telescopic end of the electric push rod 11 and the pressing rod 23 are both slidably connected to the adjusting tube 12. A second spring 24 is fixedly connected between the telescopic end of the electric push rod 11 and the adjusting tube 12. The pressing rod 23 is used to push the fixing ring 21 downward. A separating assembly is provided on the rotating sleeve 6, and the separating assembly is used to drive the lifting plate 7 to move upward, so that the pressing wheel 9 is separated from the fabric.

[0046] Further, as Figures 5-9 shown, the fixing ring 21 is provided with circumferentially distributed convex strips, and the convex strips are used to increase the contact area between the fixing ring 21 and the pressing rod 23.

[0047] Further, as Figure 7 and Figure 9 shown, the separating assembly includes an adjusting ring 25. The adjusting ring 25 is slidably connected to the rotating sleeve 6. A pull rope 26 is fixedly connected between the adjusting ring 25 and the upper side surface of the lifting plate 7. The pull rope 26 passes through the rotating sleeve 6, and the adjusting ring 25 is located on the moving path of the fixing ring 21.

[0048] The above solution provides a way to drive the lifting plate 7 to move upward when the fixing frame 22 moves downward to fix the fabric edge, so that the pressing wheel 9 is separated from the fabric and no longer presses the fabric; in this embodiment, the telescopic end of the electric push rod 11 is slidably connected to the adjusting tube 12, used to enable the telescopic end of the electric push rod 11 to drive the pressing rod 23 to move downward relative to the adjusting tube 12. The elastic coefficient of the second spring 24 is greater than that of the first spring 14. The lower end of the pressing rod 23 is made of rubber material, used to cooperate the pressing rod 23 with the convex strips on the fixing ring 21. After the rubber of the pressing rod 23 is pressed against the convex strips of the fixing ring 21, the contact area between the pressing rod 23 and the fixing ring 21 increases, increasing the resistance when the pressing rod 23 and the fixing ring 21 move relative to each other, thereby improving the fixing effect on the fixing ring 21. Initially, the lower side surface of the adjusting ring 25 is in contact with the rotating sleeve 6, and the pull rope 26 is in a loose state. The length of the pull rope 26 in the figure is only for reference, and the length of the pull rope 26 can be adjusted according to the actual situation. The pull rope 26 is used to drive the lifting plate 7 to move upward when the fixing ring 21 pushes the adjusting ring 25 downward.

[0049] Workflow: During the process of the laser cutter 5 cutting the fabric, when the vision sensor detects that the cutting edge behind the cutting area of the fabric warps, the vision sensor transmits a signal to the control terminal to activate the electric push rod 11. The telescopic end of the electric push rod 11 drives the extrusion rod 23 to move downward. At the same time, the telescopic end of the electric push rod 11 drives the adjustment tube 12 to move downward through the second spring 24, so that the adjustment tube 12 drives the L-shaped rod 8 to move downward through the extrusion lifting plate 7. The lifting plate 7 moves downward to compress the first spring 14. At the same time, the L-shaped rod 8 drives the extrusion wheel 9 to move downward to extrude the warped position of the fabric. During this process, the lifting plate 7 moves downward and pulls the pull rope 26, so that the pull rope 26 is gradually tightened. After the pull rope 26 is tightened, the lifting plate 7 continues to move downward and drives the adjustment ring 25 to move upward through the pull rope 26 until the upper side of the adjustment ring 25 contacts the rotating sleeve 6, and then the adjustment ring 25 stops moving. The convex ring 16 moves to the lower end of the guide groove 15, the telescopic end of the electric push rod 11 stops extending, and the extrusion wheel 9 stops moving and extrudes the fabric to a flat state. At this time, the length of the telescopic end of the electric push rod 11 extending is referred to as one generation.

[0050] After the fabric no longer warps, the pressure received by the pressure sensor on the electric push rod 11 decreases. The telescopic end of the electric push rod 11 drives the adjustment tube 12 to move upward to reset. The lifting plate 7 moves upward and drives the extrusion wheel 9 to move upward to reset through the L-shaped rod 8. The first spring 14 pushes the lifting plate 7 upward to reduce the pulling force on the pull rope 26. At this time, the adjustment ring 25 moves downward to reset under the action of gravity.

[0051] During the process of the extrusion wheel 9 extruding the fabric, when it is necessary to adjust the cutting direction of the fabric, the staff activates the electric push rod 11 through the control terminal. The telescopic end of the electric push rod 11 continues to extend. At this time, the lifting plate 7 cannot move downward. The telescopic end of the electric push rod 11 drives the extrusion rod 23 to move downward and compress the second spring 24. When the lower part of the extrusion rod 23 contacts the fixed ring 21, the extrusion rod 23 pushes the fixed ring 21 to move downward. The fixed ring 21 drives the fixed frame 22 to move downward and slightly compress the elastic member 211. As the fixed ring 21 moves downward, when the fixed ring 21 contacts the adjustment ring 25, the fixed ring 21 pushes the adjustment ring 25 to move downward. The adjustment ring 25 drives the lifting plate 7 to move upward through the pull rope 26, so that the lifting plate 7 drives the extrusion wheel 9 to move upward through the L-shaped rod 8, reducing the extrusion force of the extrusion wheel 9 on the fabric, and avoiding driving the fabric to move and shift during the movement of the extrusion wheel 9, resulting in the fabric being misaligned and affecting the normal cutting of the fabric. Until the fixed frame 22 presses the fabric into a flat state and the telescopic end of the electric push rod 11 stops moving downward, the electric push rod 11 is turned off. At this time, the length of the telescopic end of the electric push rod 11 extending is referred to as two generations. The fixed ring 21 stops moving downward, and the lifting plate 7 stops moving upward.

[0052] After the above electric push rod 11 is closed, the motor 18 is started. The output shaft of the motor 18 drives the external gear ring 20 to rotate through the gear 19. Taking the example that the laser knife 5 changes from moving backward to moving rightward, the external gear ring 20 drives the rotating sleeve 6 to rotate clockwise by 90°( Figure 8 , viewed from top to bottom). The rotating sleeve 6 drives the lifting plate 7 and the guide frame 13 to rotate. The lifting plate 7 and the guide frame 13 respectively drive the parts thereon to rotate synchronously. At this time, the fixed ring 21 is fixed by the pressing rod 23 and does not rotate, causing the elastic member 211 to gradually store energy. When the rotation of the rotating sleeve 6 is completed, the position of the pressing wheel 9 is adjusted. The motor 18 is turned off, and the extended length of the telescopic end of the electric push rod 11 changes from two to one. During this process, the pressing rod 23 no longer presses the fixed ring 21, and the elastic member 211 resets and drives the fixed ring 21 to move upward, separating the fixed frame 22 from the fabric, causing the elastic member 211 to drive the fixed frame 22 to rotate by 90°. At the same time, the pressing force of the fixed ring 21 on the adjusting ring 25 decreases, the upward pulling force of the adjusting ring 25 on the lifting plate 7 through the pull rope 26 decreases, the second spring 24 extends and resets and presses the lifting plate 7 downward through the adjusting tube 12, and the lifting plate 7 drives the parts thereon to move downward again to make the pressing wheel 9 press the fabric again. When the fixed ring 21 stops moving, the fixed frame 22 stops moving, and the device completes the adjustment of the position of the pressing wheel 9. When the cutting direction of the fabric changes again, the motor 18 is started again and the above adjustment of the position of the pressing wheel 9 is repeated.

[0053] After the fabric cutting is completed, the telescopic end of the electric push rod 11 retracts and resets. The lifting plate 7 drives the pressing wheel 9 to reset through the L-shaped rod 8 until the motor 18 is started after the lifting plate 7 is reset. The output shaft of the motor 18 rotates in the reverse direction, causing the rotating sleeve 6 to drive the parts thereon to rotate and reset in the reverse direction. Finally, the first sliding frame 2 and the second sliding frame 3 drive the sliding block 4 and the parts thereon to move and reset in the reverse direction.
