Description

Technical Field

[0001] This invention belongs to the field of fabric cutting technology, and specifically relates to a garment fabric cutting device. Background Technology

[0002] A garment fabric cutting device is a machine used to cut fabrics. Its working principle is to use a cutting blade to cut the fabric. It is a very important piece of equipment in the textile processing field. It can improve production efficiency, reduce labor costs, and at the same time ensure cutting accuracy and quality.

[0003] When cutting fabric, the garment fabric cutting device uses a matching conveying mechanism to transport the fabric to be cut to the cutting station, and then the cutting mechanism completes the cutting operation. At the same time, the fixing mechanism fixes the position of the fabric during the cutting process to prevent the fabric from shifting and affecting the cutting accuracy.

[0004] In the current technology, the fixing methods used in current garment fabric cutting devices are relatively simple. Generally, the fabric is fixed by pressing or tensioning. Especially when cutting multi-layered fabrics, since pressing is usually done at the edges, the fixing force distribution is relatively uneven and the adaptability to fabrics of different thicknesses and materials is poor. On the other hand, tensioning can easily lead to stress concentration, causing the fabric to stretch and deform, which in turn affects the dimensional accuracy of the finished product and reduces the overall cutting accuracy and finished product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a garment fabric cutting device to reduce the problem of affecting cutting accuracy due to displacement and deformation between multiple layers of fabric during the cutting process.

[0006] According to one aspect, to achieve the above objectives, embodiments of the present invention provide a garment fabric cutting device, including a device frame on which a conveyor is mounted, and further comprising: A support frame is fixedly installed at the bottom of the device frame, and a longitudinal adjustment frame is slidably installed on the support frame via a sliding frame; A transverse sliding frame, which is slidably mounted on the longitudinal adjusting frame; A cutting assembly is installed at the bottom of the transverse sliding frame and is used to adjust the cutting position according to the cutting path and to cut the garment fabric. The pressing assembly is installed at the bottom of the transverse sliding frame and is used to fix the position of the fabric during the fabric cutting process. The positioning components are installed inside both the support frame and the longitudinal positioning frame, and are used to push the cutting component to move along the cutting path.

[0007] To control the cutting position and cut the garment fabric, the cutting assembly includes: A sliding frame, which is slidably mounted on the bottom of the transverse sliding frame; A driving component is mounted on the transverse sliding frame, and the output end of the driving component is fixedly connected to the sliding frame; A drive frame is fixedly installed at the bottom of the sliding frame, and a first motor is fixedly installed on the sliding frame; A cutting section, which is installed at the bottom of the drive frame, is used to cut the fabric.

[0008] For cutting garment fabric, the cutting section includes: A pneumatic cutter is rotatably mounted on the bottom of the drive frame, and a pressure foot is installed at the blade shank position at the bottom of the pneumatic cutter; The drive frame contains two drive gears that are rotatably mounted inside. The two drive gears mesh with each other. One drive gear is fixedly connected to the output end of the first motor, and the other drive gear is fixedly connected to the pneumatic cutter.

[0009] To secure the fabric position during garment cutting, the pressing assembly includes: A positioning sleeve is fixedly installed at the bottom of the drive frame. The positioning sleeve is coaxially arranged with the pneumatic cutter. A sliding sleeve is coaxially slidably fitted on the positioning sleeve. A rotating sleeve, which is rotatably mounted on the positioning sleeve; A pressing part is installed at the bottom of the sliding sleeve and is used to fix the fabric during fabric cutting.

[0010] The inner wall of the rotating sleeve is threadedly engaged with the outer wall of the sliding sleeve, and the sliding sleeve can move along the axial direction of the positioning sleeve when the rotating sleeve rotates.

[0011] Based on the aforementioned scheme, the pressing part includes an annular elastic pad, which is coaxially fixedly installed at the bottom of the sliding sleeve. An installation ring, a flexible ring, and a pressing ring are sequentially coaxially installed at the bottom of the annular elastic pad.

[0012] To adjust the longitudinal position of the sliding frame, the adjustment assembly includes: A first screw is rotatably mounted inside the bearing frame, and a first nut is threaded onto the first screw, which is fixedly connected to the sliding frame. The second motor is fixedly mounted on the support frame, and the output end of the second motor is fixedly connected to the first screw. The sliding rods are fixedly installed on both sides of the device frame, and the sliding rods are slidably engaged with the sliding frame.

[0013] To adjust the lateral position of the sliding frame, a second screw is also included. The second screw is rotatably installed inside the longitudinal adjustment frame. A second nut is threaded onto the second screw and is fixedly connected to the lateral sliding frame. The third motor is fixedly mounted on the longitudinal adjustment frame, and its output end is fixedly connected to the second screw.

[0014] To reduce the relative slippage between layers of fabric during the conveying of multi-layer fabric, a pressure roller is also included. The pressure roller is rotatably mounted on the feed end of the device frame and is located on the upper part of the conveyor. An elastic sleeve is coaxially mounted on the pressure roller, and the elastic sleeve can be replaced with different sizes according to the thickness and number of layers of the fabric. Both ends of the pressure roller are coaxially mounted with follower rollers, which abut against the conveyor belt on the conveyor.

[0015] 1.

The flexible ring is made of high-density sponge material, and the pressure ring is made of polished stainless steel with a rounded chamfer. This structure can provide a soft and stable clamping force through elastic compression, avoiding the problem of indentation on thin materials and insufficient clamping on thick materials. It can also reduce fabric friction and prevent snagging and scratching. During the cutting process, it can also automatically smooth out fabric wrinkles and suppress relative sliding between layers of fabric, thereby ensuring cutting accuracy.

The garment fabric cutting device provided in this embodiment of the invention, through the design of pressure roller, elastic sleeve and follower roller, the elastic sleeve can be changed to different sizes according to the fabric thickness and number of layers. During use, the follower rollers at both ends of the pressure roller abut against the conveyor belt of the conveyor and can rotate synchronously with the conveyor to initially smooth and press the fabric in the conveyor, ensuring that the layers of multi-layer fabric are tightly bonded, reducing wrinkles generated during the conveying process, and further reducing the risk of relative displacement between the layers of fabric during cutting.

[0027] Please see Figures 1 to 10 This document illustrates a garment fabric cutting device according to an embodiment of the present invention. The device includes a frame 1, on which a conveyor 2 is mounted. It also includes a support frame 3, a transverse sliding frame 6, a cutting assembly, a pressing assembly, and an adjusting assembly. The support frame 3 is fixedly mounted at the bottom of the frame 1. A longitudinal adjusting frame 5 is slidably mounted on the support frame 3 via a sliding frame 4. The transverse sliding frame 6 is slidably mounted on the longitudinal adjusting frame 5. The cutting assembly is mounted at the bottom of the transverse sliding frame 6 and is used to adjust the cutting position according to the cutting path and to cut the garment fabric. The cutting assembly includes a sliding frame 7, a driving component 8, a rotating frame 9, and a cutting section. The sliding frame 7 is slidably mounted at the bottom of the transverse sliding frame 6. The driving component 8 is mounted on the transverse sliding frame 6, and its output end is fixedly connected to the sliding frame 7. The driving component 8 is preferably an electric cylinder. The rotating frame 9 is fixedly mounted at the bottom of the sliding frame 7, and a first motor 10 is fixedly mounted on the sliding frame 7. The cutting section is mounted at the bottom of the rotating frame 9 and is used to cut the fabric.

[0028] Among them, such as Figure 1 The arrow B shown indicates the direction of fabric movement. That is, during the cutting operation, the conveyor 2 transports the fabric to be cut in the direction shown by arrow B.

[0029] When the fabric needs to be cut, the fabric to be cut is placed on the conveyor 2 through the upper device, and then the conveyor 2 is turned on to transport the fabric. When the fabric moves to the cutting position, the drive component 8 is turned on. The drive component 8 pushes the sliding frame 7 to move downward. At this time, the cutting part is in working state. When the cutting part is in working position, the relative positions of the sliding frame 4 and the carrier frame 3 are adjusted according to the preset line by setting the adjustment component, and the relative positions of the longitudinal adjustment frame 5 and the transverse sliding frame 6 are adjusted respectively, thereby adjusting the position of the cutting part to cut the garment fabric.

[0030] During the cutting process, conveyor 2 is in the off state.

[0031] Before cutting the fabric, the position of the pressing component needs to be manually adjusted according to the thickness and number of layers of the fabric to ensure that the pressing component is in contact with the fabric when the cutting part is in the working position, and to prevent the fabric from slipping. When cutting multi-layered fabrics, it can also largely avoid relative movement between the multi-layered fabrics, thus improving the accuracy of cutting.

[0032] The cutting section includes a pneumatic cutter 11 and a transmission gear 13. The pneumatic cutter 11 is rotatably mounted on the bottom of the drive frame 9. A pressure foot 12 is installed at the blade bar position at the bottom of the pneumatic cutter 11. Two transmission gears 13 are rotatably mounted inside the drive frame 9. The two transmission gears 13 mesh with each other. One transmission gear 13 is fixedly connected to the output end of the first motor 10, and the other transmission gear 13 is fixedly connected to the pneumatic cutter 11.

[0033] During the process of cutting the garment fabric, it is also necessary to adjust the position of the pneumatic cutter 11 according to the path. At this time, the first motor 10 is turned on, and the first motor 10 transmits power to another transmission gear 13 through the transmission gear 13 at the output end, thereby driving the pneumatic cutter 11 to rotate, and then adjusting the position of the pneumatic cutter 11 according to the cutting path.

[0034] When cutting clothing fabric, first turn on the pneumatic cutter 11. The pneumatic cutter is a cutting tool powered by compressed air. The compressed air drives the cutter head or blade to reciprocate, thereby cutting the material. When cutting the fabric, the blade will continuously reciprocate to cut the material. During this process, the presser foot 12 further reduces the possibility of the fabric moving during the cutting process and improves the cutting accuracy.

[0035] A pressing assembly is installed at the bottom of the transverse sliding frame 6 to fix the fabric position during the fabric cutting process. The pressing assembly includes a positioning sleeve 14, a rotating sleeve 16, and a pressing part. The positioning sleeve 14 is fixedly installed at the bottom of the drive frame 9. The positioning sleeve 14 is coaxially arranged with the pneumatic cutter 11. A sliding sleeve 15 is coaxially slidably mounted on the positioning sleeve 14. The rotating sleeve 16 is rotatably mounted on the positioning sleeve 14. The inner wall of the rotating sleeve 16 is threadedly engaged with the outer wall of the sliding sleeve 15. When the rotating sleeve 16 rotates, the sliding sleeve 15 can move along the axial direction of the positioning sleeve 14. The pressing part is installed at the bottom of the sliding sleeve 15 to fix the fabric during the fabric cutting process.

[0036] Before cutting the fabric, the position of the pressing part needs to be adjusted. At this time, the rotating sleeve 16 is turned. The rotating sleeve 16 pushes the sliding sleeve 15 to move through the nut that is adapted to the outer wall of the sliding sleeve 15. The sliding sleeve 15 moves along the axis of the positioning sleeve 14, thereby adjusting the position of the pressing part.

[0037] The pressing part includes an annular elastic pad 17, which is coaxially fixedly installed at the bottom of the sliding sleeve 15. An installation ring 18, a flexible ring 19 and a pressing ring 20 are sequentially coaxially installed at the bottom of the annular elastic pad 17.

[0038] The flexible ring 19 can be made of soft, high-density sponge or other materials, and the pressure ring 20 can be made of stainless steel or other metal materials. The side of the pressure ring 20 that contacts the fabric is polished to make it smooth and have low friction. The side of the pressure ring 20 that contacts the fabric also needs to be chamfered.

[0039] After adjusting the position of the pressure ring 20, when the pneumatic cutter 11 moves to the working position, the pressure ring 20 is in contact with the fabric. At this time, both the annular elastic pad 17 and the flexible ring 19 are compressed to a certain extent, so that the pressure ring 20 and the fabric maintain a certain pressure, which plays a pressing role. At the same time, when encountering fabric wrinkles during the cutting process, the pressure ring 20 can also be automatically adjusted to a certain extent under the action of the flexible ring 19, which is convenient for smoothing out fabric wrinkles and ensuring cutting accuracy.

[0040] Both the support frame 3 and the longitudinal adjustment frame 5 are equipped with adjustment components to push the cutting component to move along the cutting path. The adjustment components include a first screw 21, a second motor 23, and a slide rod 24. The first screw 21 is rotatably installed inside the support frame 3, and a first nut 22 is threaded onto the first screw 21. The first nut 22 is fixedly connected to the slide frame 4. The second motor 23 is fixedly installed on the support frame 3, and the output end of the second motor 23 is fixedly connected to the first screw 21. Slide rods 24 are fixedly installed on both sides of the device frame 1, and the slide rods 24 slide with the slide frame 4. The device also includes a second screw 25. The second screw 25 and a third motor 27 are rotatably installed inside the longitudinal adjustment frame 5. A second nut 26 is threaded onto the second screw 25, and the second nut 26 is fixedly connected to the transverse sliding frame 6. The third motor 27 is fixedly installed on the longitudinal adjustment frame 5, and the output end of the third motor 27 is fixedly connected to the second screw 25.

[0041] Among them, the first motor 10, the second motor 23 and the third motor 27 are all set as stepper motors with precise transmission.

[0042] When adjusting the relative position of the sliding frame 4 and the support frame 3, the second motor 23 is turned on. The second motor 23 drives the first screw 21 to rotate, thereby pushing the first nut 22 to move. The movement of the first nut 22 pushes the sliding frame 4 to move within the support frame 3, thereby pushing the longitudinal adjustment frame 5 to move. When adjusting the relative position of the longitudinal adjustment frame 5 and the transverse sliding frame 6, the third motor 27 is turned on. The third motor 27 drives the second screw 25 to rotate, thereby pushing the second nut 26 to move. The movement of the second nut 26 pushes the transverse sliding frame 6 to move on the longitudinal adjustment frame 5, thereby adjusting the cutting position of the pneumatic cutter 11 according to the preset cutting path.

[0043] Furthermore, it also includes a pressure roller 28, which is rotatably mounted on the feed end of the device frame 1. The pressure roller 28 is located on the upper part of the conveyor 2. An elastic sleeve 29 is coaxially mounted on the pressure roller 28. The elastic sleeve 29 can be replaced with different sizes according to the thickness and number of layers of the fabric. Both ends of the pressure roller 28 are coaxially mounted with follower rollers 30. The follower rollers 30 abut against the conveyor belt on the conveyor 2. The part of the follower rollers 30 that contacts the conveyor belt can also be equipped with an anti-slip strip.

[0044] As conveyor 2 starts, the conveyor belt on conveyor 2 begins to move. At this time, through the action of follower roller 30, the follower roller 30 can be driven to rotate during the movement of the conveyor belt, thereby driving pressure roller 28 to rotate. Through the setting of elastic sleeve 29, it comes into contact with the fabric (the thickness of elastic sleeve 29 needs to be selected according to the thickness of the fabric to be cut and the number of stacked layers, which will not be elaborated here). This can initially smooth out the wrinkles on the fabric that has just been placed on conveyor 2. If it is a multi-layered fabric, it can also be initially pressed to ensure that the contact between each layer of fabric is flatter and more stable, and that relative movement is less likely to occur during cutting.

[0045] The working principle or usage process of this invention is as follows: When the fabric needs to be cut, the fabric to be cut is placed on the conveyor 2 through the upper device, and then the conveyor 2 is turned on to transport the fabric. At this time, through the action of the follower roller 30, the follower roller 30 can be driven to rotate during the movement of the conveyor belt, thereby driving the pressure roller 28 to rotate. Through the setting of the elastic sleeve 29, it comes into contact with the fabric, and the wrinkles on the fabric during the transport process can be initially smoothed. If it is a multi-layered fabric, it can also be initially pressed to ensure that the contact between each layer of fabric is more flat and stable, and it is less likely to move relative to each other during cutting.

[0046] Before cutting the fabric, the rotating sleeve 16 needs to be turned. The rotating sleeve 16 pushes the sliding sleeve 15 to move through the nut that is adapted to the outer wall of the sliding sleeve 15. The sliding sleeve 15 moves along the axis of the positioning sleeve 14, thereby pushing the mounting ring 18 to move, ensuring that the pressure ring 20 is in contact with the fabric when the pneumatic cutter 11 moves to the working position. When the fabric moves to the cutting position, the pneumatic cutter 11 is turned on, and cutting can begin.

[0047] When the drive unit 8 is activated, it pushes the sliding frame 7 downward, and the cutting section is in working condition. When the cutting section is in working position, the second motor 23 is activated, and the second motor 23 drives the first screw 21 to rotate, thereby pushing the first nut 22 to move. By moving the first nut 22, the sliding frame 4 can be pushed to move within the support frame 3, thereby pushing the longitudinal adjustment frame 5 to move. When adjusting the relative position of the longitudinal adjustment frame 5 and the transverse sliding frame 6, the third motor 27 is activated, and the third motor 27 drives the second screw 25 to rotate, thereby pushing the second nut 26 to move. By moving the second nut 26, the transverse sliding frame 6 can be pushed to move on the longitudinal adjustment frame 5, thereby adjusting the cutting position of the pneumatic cutter 11 according to the preset cutting path, and thus cutting the fabric by the pneumatic cutter 11.

[0048] During the cutting process, both the annular elastic pad 17 and the flexible ring 19 are compressed to a certain extent, thereby maintaining a certain pressure between the pressure ring 20 and the fabric, which plays a pressing role. At the same time, when encountering fabric wrinkles during the cutting process, the pressure ring 20 can also be automatically adjusted to a certain extent under the action of the flexible ring 19, which is convenient for smoothing out fabric wrinkles and ensuring cutting accuracy. Meanwhile, the first motor 10 is turned on during the cutting process. The first motor 10 transmits power to another transmission gear 13 through the transmission gear 13 at the output end, thereby driving the pneumatic cutter 11 to rotate. Then, the position of the pneumatic cutter 11 is adjusted according to the cutting path until the cutting is completed. After the cutting is completed, the drive component 8 is retracted, and the cut fabric is removed by the conveyor 2.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
