Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and in particular to a shirt production device based on laser cutting. Background Technology

[0002] Laser cutting is a process that uses laser technology to precisely cut textiles. It has significant advantages such as high precision, high efficiency, and high automation. In the shirt production process, laser cutting is often used for the initial trimming of fabric. However, when existing laser cutting equipment cuts fabric, the cut edges deform due to excessive heat, resulting in curling edges. This problem is particularly prominent when cutting thicker shirt fabrics, especially fleece-lined shirt fabrics. Because the heat generated during laser cutting is difficult to dissipate in time, the heat generated during cutting increases significantly when cutting thicker fabrics, making the curling edge deformation even more severe. The curled-up areas of the fabric pull on the cut area, causing the cut to become uneven and the cut position of the fabric to change. Existing equipment can only flatten the fabric as a whole during the cutting process and cannot flatten and trim the curled-up areas, resulting in a reduction in the precision of laser cutting and the quality of fabric cutting. Summary of the Invention

[0003] This invention provides a shirt production device based on laser cutting, which solves the problem that the edges of the fabric tend to curl up during the cutting process, affecting the cutting quality of the fabric.

[0004] The technical solution of the present invention is as follows: a shirt production device based on laser cutting, comprising a cutting bed, a conveyor belt and a control terminal on the cutting bed, a first sliding frame fixedly connected to the cutting bed, a second sliding frame on the first sliding frame, a sliding block slidably connected to the second sliding frame, a laser blade fixedly connected to the sliding block, the laser blade being used to cut the fabric, the laser blade being provided with a rotating sleeve, the rotating sleeve being slidably connected to a lifting plate, the lifting plate being slidably connected to symmetrically distributed L-shaped rods, a squeezing wheel being provided on the side of the L-shaped rods away from the lifting plate via a one-way rotating shaft, the squeezing wheel being used to squeeze the raised part of the fabric, so that the fabric at the cut point is in a flat state, and a power component being provided on the laser blade, the power component being used to drive the squeezing wheel downward, so that the squeezing wheel squeezes the raised part of the fabric at the cut point.

[0005] As a preferred embodiment, the power assembly includes a support plate fixedly connected to the sliding block, an electric push rod fixedly connected to the support plate, a pressure sensor mounted on the electric push rod, an adjusting tube at the telescopic end of the electric push rod for moving the lifting plate, a guide frame fixedly connected to the rotating sleeve, the guide frame slidably connected to the L-shaped rod, a first spring fixedly connected between the guide frame and the lifting plate, and a guide assembly mounted on the guide frame for driving the symmetrically distributed L-shaped rods to converge, causing the extrusion roller to stretch the raised fabric.

[0006] As a preferred embodiment, the guide assembly includes symmetrically distributed convex rings, which are respectively fixed to the middle of adjacent L-shaped rods. The guide frame is provided with symmetrically distributed guide grooves, and the convex rings slide within adjacent guide grooves.

[0007] As a preferred embodiment, the distance between the symmetrically distributed guide grooves decreases as the horizontal distance between them and the laser blade increases.

[0008] As a preferred embodiment, the extrusion roller is provided with circumferentially distributed guide strips, and the guide strips are used to increase the friction between the extrusion roller and the fabric.

[0009] As a preferred embodiment, the device further includes a rotating assembly disposed on the support plate. The rotating assembly 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 to the laser blade. 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 to the laser blade and meshes with the gear. A fixing assembly is provided on the rotating sleeve. The fixing assembly is used to press and fix the raised part of the fabric when adjusting the position of the extrusion wheel.

[0010] As a preferred embodiment, the fixing component includes a fixing ring, which is rotatably and slidably connected to the rotating sleeve. An elastic element is provided between the fixing ring and the rotating sleeve. A fixing frame is fixedly connected to the fixing ring. The fixing frame is used to fix the raised position of the fabric. A transmission component is provided on the telescopic end of the electric push rod. The transmission component is used to drive the fixing frame to move when the lifting plate rotates, and to fix the raised position of the fabric.

[0011] As a preferred embodiment, the transmission assembly includes a pressing rod, which is fixedly connected to the telescopic end of the electric push rod. Both the telescopic end of the electric push rod and the pressing rod are slidably connected to the adjusting tube. A second spring is fixedly connected between the telescopic end of the electric push rod and the adjusting tube. The pressing rod is used to push the fixed ring to move downward.

The pull rope passes through the rotating sleeve, and the adjusting ring is located on the moving path of the fixed ring.

[0014] The beneficial effects are as follows: 1. During the fabric cutting process, the present invention uses an L-shaped rod to drive the extrusion wheel to move downwards and extrude the fabric at the raised position, thereby reducing the pulling force of the raised position on the fabric cutting position, reducing the deformation of the fabric at the cutting position, and thus improving the cutting accuracy of the fabric.

[0015] 2. During the downward extrusion of the fabric, the present invention guides the convex ring through the guide groove, causing the extrusion roller to pull the fabric away from the laser blade, making the cut of the fabric smoother and thus further improving the cutting accuracy of the device.

[0016] 3. When the position of the extrusion roller needs to be adjusted, the present invention fixes the cutting edge with a fixing frame and lifts the extrusion roller upward to separate the extrusion roller from the fabric, ensuring that the fabric does not shrink or change when the extrusion roller moves, thereby ensuring the fixing effect on the cut part of the fabric.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0028] A shirt production device based on laser cutting, such as Figures 1-6 As shown, the device includes a cutting bed 1, on which a conveyor belt and a control terminal are installed. A first sliding frame 2 is fixedly connected to the cutting bed 1, and a second sliding frame 3 is installed on the first sliding frame 2. A sliding block 4 is slidably connected to the second sliding frame 3, and a laser blade 5 is fixedly connected to the sliding block 4. The laser blade 5 is used to cut the fabric. The laser blade 5 is equipped with a rotating sleeve 6, and a lifting plate 7 is slidably connected to the rotating sleeve 6. The lifting plate 7 is slidably connected to symmetrically distributed L-shaped rods 8. A pressing wheel 9 is installed on the side of the L-shaped rods away from the lifting plate 7 via a one-way rotating shaft. The pressing wheel 9 is used to press the fabric at the raised position, so that the fabric at the cut is in a flat state. A power component is installed on the laser blade 5, which is used to drive the pressing wheel 9 to move downward, so that the pressing wheel 9 presses the fabric at the raised position at the cut.

[0029] The above solution provides a method to press and flatten the fabric when it curls up near the cut point during the fabric cutting process, reducing the impact of the curled-up position on the cut point. The conveyor belt of the cutting bed 1 is used to transport the fabric forward to achieve continuous fabric production. The control terminal of the cutting bed 1 is electrically connected to the electrical components described below to control the start and stop times of the electrical components. The first sliding frame 2 and the second sliding frame 3 are both existing electric slide rails, and their specific structures will not be described in detail. The first sliding frame 2 and the second sliding frame 3 together drive the sliding block 4 to move in the front-back and left-right directions. The laser knife 5 is an existing device, and its internal structure and usage methods will not be described in detail. In this embodiment, the laser knife 5 is fixedly connected to the rotating sleeve 6. There are two L-shaped rods 8 on the lifting plate 7. The number of L-shaped rods 8 can be adjusted according to the actual situation. A vision sensor is set on the laser knife 5. The vision sensor is not shown in the diagram. This vision sensor is used to detect whether the edge of the fabric is curled up after cutting. The extrusion wheel 9 is used to press down the curled-up position near the cut point of the fabric to achieve the desired effect. Figure 1 Taking the direction as an example, under the action of the unidirectional rotating shaft, the extrusion wheel 9 rotates when it moves backward, and does not rotate when it moves forward.

[0030] Further, such as Figures 3-9 As shown, the power assembly includes a support plate 10, which is fixed to the sliding block 4. An electric push rod 11 is fixed to the support plate 10. A pressure sensor is installed on the electric push rod 11. An adjustment tube 12 is installed at the telescopic end of the electric push rod 11. The adjustment tube 12 is used to drive the lifting plate 7 to move. A guide frame 13 is fixed to the rotating sleeve 6. The guide frame 13 is slidably connected to the L-shaped rod 8. A first spring 14 is fixed between the guide frame 13 and the lifting plate 7. A guide assembly is installed 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 extrusion wheel 9 stretches the raised fabric.

[0031] In the above scheme, the support plate 10 is located on the upper side of 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 extrusion wheel 9. When the fabric no longer curls up, the reverse force of the fabric on the extrusion wheel 9 decreases. After the reverse force on the extrusion wheel 9 is less than a specified value (the specified value is the pressure when the extrusion wheel 9 extrudes and flattens the fabric, and the specified value can be adjusted according to the actual situation), the telescopic end of the electric push rod 11 drives the adjusting 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 adjusting tube 12, which is used to make the electric push rod 11 directly drive the adjusting tube 12 to move downward and extrude the lifting plate 7. The first spring 14 is used to push the lifting plate 7 to move upward and reset.

[0032] Further, such as Figures 4-6 and Figure 8As shown, the guide assembly includes symmetrically distributed convex rings 16, which are fixed to the middle of adjacent L-shaped rods 8. The guide frame 13 is provided with symmetrically distributed guide grooves 15, and the convex rings 16 slide within the adjacent guide grooves 15.

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

[0034] Further, such as Figure 4 and Figure 5 As shown, the extrusion roller 9 is provided with circumferentially distributed guide strips 17, and the guide strips 17 are used to increase the friction between the extrusion roller 9 and the fabric.

[0035] The above solution provides a method in which, during the process of driving the extrusion roller 9 to move downward to extrude the fabric to the raised position, the two extrusion rollers 9 are driven to move towards each other and away from the laser knife 5, thereby stretching the fabric to the raised position. The guide frame 13 is provided with two through slots, and the two L-shaped rods 8 slide in adjacent through slots respectively. The distance between the two through slots gradually decreases from the rear to the front. The maximum diameter of the convex ring 16 is greater than the width of the through slot on the guide frame 13. The guide groove 15 is composed of a vertical groove and an inclined groove. The vertical groove of the guide groove 15 is used to guide the convex ring 16 to move downward vertically, and the inclined groove of the guide groove 15 is used to guide the two convex rings 16 to move forward and bring the two convex rings 16 closer to each other during the forward movement. The shape of the guide groove 15 can be adjusted according to the actual usage.

[0036] Workflow: When it is necessary to cut shirt fabric (hereinafter referred to as fabric), the worker lays the fabric flat on the conveyor belt of the cutting bed 1, and then starts the conveyor belt through the control terminal. The conveyor belt moves the fabric forward (the starting and stopping of electrical components are all completed through the control terminal) until the front part of the fabric moves under the laser cutter 5, at which point the conveyor belt stops. The initial position of the laser cutter 5 is referenced. Figure 1 At this time, the staff sets the path for the first sliding frame 2 and the second sliding frame 3 to move 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 movement 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 moves the parts on it through the rotating sleeve 6. After cutting this section of fabric, the staff collects the cut fabric, then starts the conveyor belt again and adjusts the position of the fabric to continue cutting.

[0037] During the fabric cutting process described above, when the vision sensor on the laser cutter 5 detects that the edge of the fabric is raised after cutting, the control terminal activates the electric push rod 11. Taking the sliding block 4 driving the laser cutter 5 to move backward to cut the fabric as an example, the telescopic end of the electric push rod 11 drives the adjusting tube 12 to move downward. When the adjusting tube 12 contacts the lifting plate 7, the adjusting tube 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 on the pressure sensor on the electric push rod 11 increases, and the L-shaped rod 8 drives the convex ring 16 on it to move along the vertical guide groove 15. The straight groove moves downward, and at the same time, the L-shaped rod 8 drives the extrusion roller 9 to move downward and approach the fabric. During this process, when the extrusion roller 9 contacts the raised part of the fabric, the extrusion roller 9 presses down on the raised part of the fabric to reduce the impact of the raised fabric on the cutting position. At this time, the pressure on the pressure sensor on the electric push rod 11 continues to increase, and the increase in the measured value on the pressure sensor is greater than the increase in the measured value when the extrusion roller 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, the convex ring 16 enters the inclined groove of the guide groove 15. At this time, the fabric is not flattened.

[0038] After the aforementioned protruding ring 16 enters the inclined groove of the guide groove 15, with the moving direction of the left L-shaped rod 8 and its parts as a reference, under the guidance of the inclined groove of the guide groove 15, the extrusion wheel 9 continues to move downward to extrude the fabric. The L-shaped rod 8 drives the extrusion wheel 9 to move to the right and forward relative to the laser knife 5. The extrusion wheel 9 drives the fabric in the adjacent area to move to the right and forward. At this time, the extrusion wheel 9 does not rotate. The extrusion wheel 9 pulls the fabric at the raised position through the friction between the guide strip 17 and the fabric, thereby making the fabric flatter and further improving the cutting accuracy. Until the protruding ring 16 moves to the lower end of the inclined part of the guide groove 15, the electric push rod 11 closes, the L-shaped rod 8 stops moving, the extrusion 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 extrusion roller 9 stops moving downwards, the laser blade 5 drives the rotating sleeve 6 to continue moving 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 extrusion roller 9 to move together with the laser blade 5.

[0040] During the process of the extrusion roller 9 extruding the fabric, when the pressure sensor on the electric push rod 11 detects a decrease in the extrusion force, that is, a decrease in the degree of fabric warping, until the pressure sensor detects a value less than a specified value, the electric push rod 11 is activated. The telescopic end of the electric push rod 11 drives the adjusting tube 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 rods 8 to move in the opposite direction along the guide groove 15 and reset. The extrusion roller 9 separates from the fabric. The device completes the reset after the telescopic end of the electric push rod 11 is completely retracted. Afterward, when the vision detector detects that the fabric warps again, the extrusion roller 9 repeats the above process to extrude and stretch the fabric. After the fabric is cut, the first sliding frame 2 and the second sliding frame 3 drive the sliding block 4 and its parts to reset.

[0041] Further, such as Figures 4-6 and Figure 9 As shown, it also includes a rotating assembly, which is mounted 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, which is fixedly connected to the support plate 10. The rotating sleeve 6 is rotatably connected to the laser blade 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. The output shaft of the motor 18 is fixedly connected to a gear 19. The rotating sleeve 6 is fixedly connected to an external gear ring 20, which is rotatably connected to the laser blade 5. The external gear ring 20 meshes with the gear 19. A fixing assembly is provided on the rotating sleeve 6. The fixing assembly is used to press and fix the raised part 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 located behind the laser knife 5 in the direction of movement; a reducer can be provided between the output shaft of the motor 18 and the gear 19 to slow down the 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 outer gear ring 20. In this embodiment, the rotating sleeve 6 and the laser knife 5 are rotatably connected.

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

[0044] The above solution provides a way to fix the fabric cutting edge during the rotation of the extrusion wheel 9 driven by the rotating sleeve 6; the fixing ring 21 is located on the lower side of the guide frame 13, and the elastic element 211 is used to drive the fixing ring 21 to rotate and reset. In this embodiment, the elastic element 211 is a torsion spring that can be slightly compressed, which is 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, which is used to simultaneously extrude both sides of the fabric cutting position.

[0045] Further, such as Figure 9 As shown, the transmission assembly includes a pressing rod 23, which is fixedly connected to the telescopic end of the electric push rod 11. Both the telescopic end of the electric push rod 11 and the pressing rod 23 are 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 fixed ring 21 to move downward. A separation assembly is provided on the rotating sleeve 6. The separation assembly is used to drive the lifting plate 7 to move upward, so that the pressing wheel 9 separates from the fabric.

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

[0047] Further, such as Figure 7 and Figure 9 As shown, the separation assembly includes an adjusting ring 25, which is slidably connected to the rotating sleeve 6. A pull rope 26 is fixed between the adjusting ring 25 and the upper side 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 fixed ring 21.

[0048] The above solution provides a method in which the lifting plate 7 moves upward when the fixing frame 22 moves downward to fix the edge of the fabric, so that the extrusion roller 9 separates from the fabric and no longer extrudes the fabric; in this embodiment, the telescopic end of the electric push rod 11 is slidably connected to the adjusting tube 12, so that the telescopic end of the electric push rod 11 can drive the extrusion 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 extrusion rod 23 is made of rubber material, so that the extrusion rod 23 and the protrusion on the fixing ring 21 are matched. When the rubber of the extrusion rod 23 is pressed against the protrusion of the fixing ring 21, the contact area between the extrusion rod 23 and the fixing ring 21 increases, increasing the resistance when the extrusion 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 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. The length of the pull rope 26 can be adjusted according to the actual situation. The pull rope 26 is used to push the adjusting ring 25 downward when the fixing ring 21 pushes it to move downward, thereby driving the lifting plate 7 upward.

[0049] Workflow: During the process of the laser cutter 5 cutting the fabric, when the vision sensor detects that the cut edge behind the cut point of the fabric is raised, the vision sensor sends 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 adjusting tube 12 to move downward through the second spring 24, so that the adjusting tube 12 drives the L-shaped rod 8 to move downward through the extrusion lifting plate 7. The downward movement of the lifting plate 7 compresses the first spring 14, and at the same time, the L-shaped rod 8 drives the extrusion wheel 9 to move downward. The fabric is squeezed to the raised position. 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 adjusting ring 25 to move upward through the pull rope 26 until the upper side of the adjusting ring 25 contacts the rotating sleeve 6. Then the adjusting 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, the squeezing wheel 9 stops moving and squeezes the fabric to a flat state. At this time, the extension length of the telescopic end of the electric push rod 11 is called a generation.

[0050] After the fabric stops warping, the pressure on the pressure sensor on the electric push rod 11 decreases, and the telescopic end of the electric push rod 11 drives the adjusting tube 12 to move upward and reset. The lifting plate 7 moves upward and drives the squeezing wheel 9 to move upward and reset through the L-shaped rod 8. The first spring 14 pushes the lifting plate 7 to move upward and reduces the tension on the pull rope 26. At this time, the adjusting ring 25 moves downward and resets under the action of gravity.

[0051] During the fabric compression process of the extrusion roller 9, when it is necessary to adjust the cutting direction of the fabric, the operator activates the electric push rod 11 via the control terminal. The telescopic end of the electric push rod 11 continues to extend, at which point the lifting plate 7 cannot move downwards. The telescopic end of the electric push rod 11 drives the extrusion rod 23 to move downwards and compress the second spring 24. When the lower part of the extrusion rod 23 contacts the fixing ring 21, the extrusion rod 23 pushes the fixing ring 21 downwards. The fixing ring 21 drives the fixing frame 22 downwards and slightly compresses the elastic element 211. As the fixing ring 21 moves downwards, when the fixing ring 21 contacts the adjusting ring 25, the fixing ring... 21. Push the adjusting ring 25 downward. The adjusting ring 25 drives the lifting plate 7 upward through the pull rope 26. The lifting plate 7 drives the extrusion wheel 9 upward through the L-shaped rod 8, reducing the extrusion wheel 9's pressure on the fabric and preventing the fabric from shifting during the movement of the extrusion wheel 9, which would cause misalignment and affect the normal cutting of the fabric. Until the fixing 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 closed. At this time, the extension length of the telescopic end of the electric push rod 11 is referred to as the second generation. The fixing ring 21 stops moving downward and the lifting plate 7 stops moving upward.

[0052] After the electric push rod 11 is closed, the motor 18 starts. The output shaft of the motor 18 drives the external gear ring 20 to rotate through the gear 19. Taking the laser knife 5 changing from moving backward to moving to the right as an example, the external gear ring 20 drives the rotating sleeve 6 to rotate 90° clockwise. Figure 8 (Viewed from top to bottom), the rotating sleeve 6 drives the lifting plate 7 and guide frame 13 to rotate. The lifting plate 7 and guide frame 13 drive the parts on them to rotate synchronously. At this time, the fixed ring 21 is fixed by the pressing rod 23 and does not rotate, so the elastic element 211 gradually accumulates force. When the rotating sleeve 6 has finished rotating, the position of the pressing wheel 9 is adjusted, the motor 18 is turned off, and the extension 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, the elastic element 211 resets and drives the fixed ring 21 to move upward, so that the fixing frame 22 separates from the fabric, making... The elastic element 211 drives the fixed frame 22 to rotate 90°. At the same time, the squeezing 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 squeezes the lifting plate 7 downward through the adjusting tube 12. The lifting plate 7 drives the parts on it to move downward again, so that the squeezing wheel 9 squeezes the fabric again. When the fixed ring 21 stops moving, the fixed frame 22 stops moving. The device completes the adjustment of the position of the squeezing wheel 9. When the cutting direction of the fabric changes again, the motor 18 starts again and repeats the above adjustment of the position of the squeezing wheel 9.

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