Description

Technical Field

[0001] This invention relates to a sewing device, and more particularly to a multi-layer fabric anti-deviation sewing device for hat production. Background Technology

[0002] Hats are garments worn on the head, most of which cover the entire top of the head. Their primary purpose is head protection. Some hats have protruding brims to block sunlight. The appearance of a hat directly affects its aesthetic appeal and whether a customer will purchase it. Currently, multiple layers of fabric are used in hat production, but this can lead to misalignment during sewing. Therefore, anti-misalignment sewing equipment for multi-layered fabrics has been developed to solve this problem during hat production.

[0003] Currently, a multi-layer fabric anti-deviation sewing device for hat production still has some defects and shortcomings in use. The specific areas that need improvement are as follows:

[0004] 1. Current fabric anti-deviation sewing equipment cannot adjust the flatness of the feed teeth in real time according to the wear of the feed teeth, which makes it inconvenient for operators to make timely and quick adjustments during the sewing process. Therefore, it delays the sewing work of the sewing workers to a certain extent and affects the continuity of the sewing work.

[0005] 2. Current fabric anti-deviation sewing equipment cannot adjust the skewed presser foot in time, which causes the sewing needle to be out of the center of the presser foot, resulting in fabric deviation during the sewing process. Therefore, it affects the smoothness of the sewing worker's work to a certain extent.

[0006] 3. Current fabric anti-deviation sewing equipment cannot limit the movement of multiple layers of fabric, thus requiring sewing workers to manually align the multiple layers of fabric during the sewing process. This increases the workload of sewing workers and reduces sewing efficiency to some extent.

[0007] 4. Current fabric anti-deviation sewing equipment cannot clean or collect fabric scraps or thread ends on the table in a timely manner. As a result, fabric scraps or thread ends are scattered on the table and fall into the sewing equipment if not cleaned for a long time. This reduces the cleanliness and safety of the equipment during use to a certain extent.

[0008] 5. The height of current fabric anti-deviation sewing equipment is fixed and cannot be adjusted, which means that sewing workers of different heights have to raise their arms or bend over when using it, thus reducing the comfort of sewing workers to some extent.

[0009] Therefore, a multi-layer fabric anti-deviation sewing device based on hat production was proposed to solve the above problems. Summary of the Invention

[0010] The purpose of this invention is to provide a multi-layer fabric anti-deviation sewing device for hat production, in order to solve the problems mentioned in the background art, such as fabric deviation affecting the continuity, smoothness and efficiency of workers' work during the sewing process, and the inability to clean up fabric waste and thread ends in a timely manner during the work process, which to some extent reduces the cleanliness and safety of the device during use.

[0011] To achieve the above objectives, the present invention provides the following technical solution: It includes two legs, with a first support plate integrally formed between the two legs. A second support plate is slidably connected to the two legs. Adjustment plates are fixed to both ends of the second support plate by fixing bolts. An adjustment mechanism is installed between the first and second support plates. A common operating platform is welded to the two adjustment plates. A sewing machine body is mounted on the top of the operating platform. A first infrared sensor is mounted on the bottom of the sewing machine body near the feed teeth. A dust extraction mechanism is mounted on one side of the operating platform. A feed dog is bolted to the feed shaft inside the sewing machine body. Feed teeth are mounted on the feed dog via a fine-tuning mechanism. A measuring mechanism and a fabric anti-deviation mechanism are mounted on the bottom of the operating platform. A controller is mounted on the top of the operating platform.

[0012] When using a multi-layer fabric anti-deviation sewing device for hat production based on this technical solution, by setting up a micro electric push rod and a snap-fit ​​plate, the needle plate fixing screws on the needle plate can be removed, and the feed teeth can be installed on the feed tooth frame by fixing bolts. During use or not, the first infrared sensor measures the distance between the front and rear positions of the feed teeth. When the front and rear distances are different, the micro electric push rod works, and the angle of the micro electric push rod changes, which also changes the tilt angle of the feed teeth fixed on the snap-fit ​​plate. After the first infrared sensor measures, the front and rear distances of the feed teeth are consistent and then stop. The flatness of the feed teeth can be adjusted in real time according to the wear degree of the feed teeth, so as to facilitate the sewing worker to adjust the feed teeth in a timely and quick manner during the sewing process.

[0013] The adjustable mechanism allows the adjustment plate to be raised or lowered, eliminating the need for tall or short sewing workers to raise their arms or bend over, thus improving their comfort. The dust collection mechanism sucks fabric scraps and thread ends from the worktable into the dust collection box, ensuring timely cleaning and collection. This prevents fabric scraps and thread ends from scattering on the worktable or falling into the sewing equipment due to lack of cleaning, thus guaranteeing cleanliness and safety during operation.

[0014] By setting up a measuring mechanism, it is possible to measure whether the left and right positions of the presser foot are off-center, allowing sewing workers to adjust the presser foot position in time, thereby ensuring that the sewing needle is in the center of the presser foot. This prevents the fabric from shifting due to the presser foot being skewed during the sewing process. By setting up a fabric anti-deviation mechanism, adjusting the fabric anti-deviation mechanism allows several layers of fabric to be placed in several fabric sewing slots, limiting the movement of multiple layers of fabric. This also eliminates the need for sewing workers to manually align multiple layers of fabric during the sewing process.

[0015] As a preferred embodiment of the present invention, the adjusting mechanism includes a scissor frame and a first mounting frame. One end of the motor frame is welded to a first support plate. A first motor is mounted on the motor frame by fixing bolts. A gear is mounted on the output shaft of the first motor via a coupling. A gear plate meshes with the gear. A sliding block is welded to one side of the gear plate. A first sliding groove is provided on the first support plate. The sliding block is slidably connected to the first sliding groove. A second sliding groove is provided on the second support plate. A connecting block is slidably connected in the second sliding groove. Both ends of the scissor frame are movably mounted on the sliding block and the connecting block respectively via pins. The other two ends of the scissor frame are movably connected to the first support plate and the second support plate respectively via pins.

[0016] As a preferred embodiment of the present invention, each of the two support legs is provided with a limiting groove, and the two ends of the second support plate pass through the two limiting grooves respectively and are integrally connected to the opposite sides of the two adjustment plates.

[0017] As a preferred embodiment of the present invention, the vacuuming mechanism includes a vacuum box and a vacuum pump. A placement plate is integrally connected to one side of the adjustment plate. A through groove is provided on the operating table, and the vacuum box is placed in the through groove. The vacuum pump is mounted on the placement plate by fixing bolts. A connecting pipe is connected to the bottom of the vacuum box, and the other end of the connecting pipe is connected to a vacuum chamber. The other end of the vacuum chamber is connected to the suction end of the vacuum pump through a pipe and a connecting flange. A first electric push rod is installed between the placement plate and the vacuum box.

[0018] As a preferred embodiment of the present invention, the through groove is opened on the side of the sewing machine body with the sewing needle, and the opening of the dust collection box is opened on the side of the sewing machine body with the sewing needle.

[0019] As a preferred embodiment of the present invention, the fine-tuning mechanism includes a miniature electric push rod. A snap-fit ​​plate is movably connected to the tooth frame via a pin. The miniature electric push rod is movably connected to the tooth frame via a fixing member and a pin. The other end of the miniature electric push rod is movably connected to the snap-fit ​​plate via a fixing member and a pin. A feed tooth is detachably connected to the snap-fit ​​plate via a fixing bolt. The feed tooth has an opening slot through the needle plate and is located outside the needle plate. The needle plate is fixed to the operating table via a needle plate fixing screw.

[0020] As a preferred embodiment of the present invention, the measuring mechanism includes a connecting frame welded to the bottom of the operating table. A rectangular groove is provided on one side of the connecting frame, and a connecting rod is slidably connected in the rectangular groove. A first mounting bracket is welded to one end of the connecting rod. A second motor is embedded in the connecting frame. A threaded rod is mounted on the output shaft of the second motor through a coupling. The threaded rod is threadedly connected to a threaded hole provided in the first mounting frame. A second electric push rod is mounted on the top of the first mounting frame through a push rod bracket. A second mounting frame is fixedly connected to the top of the second electric push rod through a push rod bracket. A second infrared sensor is embedded in the second mounting frame.

[0021] As a preferred embodiment of the present invention, the fabric anti-deviation mechanism includes a guide rail, which is integrally welded to the bottom of the operating table. A guide plate is slidably connected inside the guide rail, and an L-shaped frame is fixedly connected to the bottom of the guide plate. The L-shaped frame has a threaded hole, and a threaded post is threadedly connected inside the threaded hole. A rotating shaft is welded to one end of the threaded post, and a bearing is movably inserted through one end of the rotating shaft. A fixing block is embedded in the outer periphery of the bearing. The fixing block is connected to the L-shaped frame through an elastic plate, and a fabric clamping plate is fixedly connected to one side of the fixing block.

[0022] As a preferred embodiment of the present invention, both the first mounting bracket and the second mounting bracket are L-shaped, and the fabric clip plate is a rectangular plate with multiple fabric placement slots.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention, by setting a miniature electric push rod and a snap-fit ​​plate, allows the needle plate fixing screws on the needle plate to be removed, and the feed teeth can be installed on the feed dog bracket by fixing bolts. During use or when not in use, the first infrared sensor measures the distance between the front and rear positions of the feed teeth. When the front and rear distances are different, the miniature electric push rod operates, and the angle of the miniature electric push rod changes, which also changes the tilt angle of the feed teeth fixed on the snap-fit ​​plate. After the first infrared sensor measures and the front and rear distances of the feed teeth are consistent, the measurement stops. The flatness of the feed teeth can be adjusted in real time according to the wear degree of the feed teeth, thus facilitating the sewing worker to adjust the feed teeth in a timely and quick manner during the sewing process. Therefore, it facilitates the sewing worker's sewing work to a certain extent and ensures the continuity of the sewing work.

[0025] 2. In this invention, by setting up a second motor, a threaded rod, and a second infrared sensor, the second motor drives the threaded rod to rotate, while the first mounting bracket slides within the rectangular groove with the connecting rod, so that the second mounting bracket is no longer located below the operating table. The second electric push rod operates, raising the second infrared sensor on the second mounting bracket to a designated position, thereby measuring whether the left and right positions of the presser foot are offset. This allows the sewing worker to adjust the presser foot position in a timely manner, ensuring that the sewing needle is centered on the presser foot. This prevents the fabric from shifting due to the presser foot being skewed during sewing, thus ensuring the smoothness of the sewing worker's work to a certain extent.

[0026] 3. This invention, through the arrangement of guide rails, guide plates, fabric clamping plates, and threaded columns, pulls the threaded rod, causing the guide plate to slide within the guide rail, so that the fabric clamping plate is no longer located below the operating table. Subsequently, the threaded column is rotated, causing the fabric clamping plate to rise, exposing several fabric placement slots on the fabric clamping plate. Then, several layers of fabric are placed in several fabric sewing slots respectively, limiting the positioning of multiple layers of fabric. This reduces the need for sewing workers to manually align multiple layers of fabric during the sewing process, thus reducing the workload of sewing workers and the efficiency of sewing to a certain extent.

[0027] 4. This invention, by setting up a dust collection box, a dust collection chamber, a dust pump, and a first electric push rod, raises the dust collection box, exposing its opening to the through slot. Then, the dust pump operates, sucking fabric scraps and thread ends from the worktable into the dust collection chamber. This allows for timely cleaning or collection of fabric scraps or thread ends on the worktable, preventing them from scattering on the worktable or falling into the sewing equipment due to prolonged lack of cleaning. Therefore, it ensures cleanliness and safety during the use of the device to a certain extent.

[0028] 5. In this invention, by setting up a first motor, gears, a toothed plate, and a scissor frame, the first motor drives the gears to rotate, and the gears mesh with the toothed plate, causing the toothed plate to slide with the sliding block in the first sliding groove, and then with the connecting block to slide in the second sliding groove, thereby changing the shape of the scissor frame, thereby raising or lowering the adjustment plate, so that sewing workers of relatively tall or short height do not need to raise their arms or bend over when using it, thus improving the comfort of sewing workers to a certain extent.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-12 This invention provides a technical solution for a multi-layer fabric anti-deviation sewing device for hat production: It includes two support legs 7, with a first support plate 13 integrally formed between the two support legs 7. A second support plate 11 is slidably connected to the two support legs 7. Adjustment plates 9 are fixed to both ends of the second support plate 11 by fixing bolts. An adjustment mechanism is installed between the first support plate 13 and the second support plate 11. A common operating platform 1 is welded to the two adjustment plates 9. A sewing machine body 3 is mounted on the top of the operating platform 1. A first infrared sensor is installed on the bottom of the sewing machine body 3 near the feed teeth 24. The machine has a dust extraction mechanism 6 installed on one side of the operating table 1. The dust extraction mechanism is installed on the side near the feed teeth 24, which can remove the scraps of fabric or thread produced by cutting and ensure the cleanliness of the operating table 1. The feed shaft inside the sewing machine body 3 is bolted with a feed tooth 28, and the feed teeth 24 are installed on the feed tooth 28 through a fine adjustment mechanism. The bottom of the operating table 1 is equipped with a measuring mechanism 4 and a fabric anti-deviation mechanism 29. The top of the operating table 1 is equipped with a controller 2, which can be a computer or other control device to control the working status of the electrical components inside the multi-layer fabric anti-deviation sewing equipment.

[0045] The adjustment mechanism includes a scissor frame 12 and a motor frame 14. One end of the motor frame 14 is welded to the first support plate 13. A first motor 15 is mounted on the motor frame 14 by fixing bolts. The output shaft of the first motor 15 is mounted with a gear 16 via a coupling. A gear plate 17 is meshed with the gear 16. A sliding block 19 is welded to one side of the gear plate 17. A first sliding groove 18 is provided on the first support plate 13. The sliding block 19 is slidably connected in the first sliding groove 18. A second sliding groove 10 is provided on the second support plate 11. A connecting block is slidably connected in the second sliding groove 10. Both ends of the scissor frame 12 are movably mounted on the sliding block 19 and the connecting block respectively by pins. The other two ends of the scissor frame 12 are movably connected to the first support plate 13 and the second support plate 11 respectively by pins. This allows the adjustment plate 9 to be raised or lowered, so that the height of the operating table matches the working height of sewing workers of different heights within a certain range, making the sewing workers more comfortable while working.

[0046] Each of the two support legs 7 has a limiting groove 8. The two ends of the second support plate 11 pass through the two limiting grooves 8 respectively and are integrally connected to the opposite sides of the two adjusting plates 9. This integral connection can be achieved by welding.

[0047] The vacuuming mechanism 6 includes a vacuum box 601 and a vacuum pump 605. The opening of the vacuum box 601 is located near the side of the sewing machine body 3 containing the sewing needle. A placement plate 20 is integrally connected to one side of an adjusting plate 9. A through groove 23 is provided on the operating table 1, located near the side of the sewing machine body 3 containing the sewing needle. The vacuum box 601 is placed in the through groove 23. The vacuum pump 605 is mounted on the placement plate 20 by fixing bolts. A connecting pipe 603, which is a flexible hose, is connected to the bottom of the vacuum box 601. The other end of the connecting pipe 603 is connected to a vacuum chamber 604. The other end of the vacuum chamber 604 is connected to... The system is connected to the suction end of the vacuum pump 605 via a pipe and connecting flange. A first electric push rod 602 is installed between the placement plate 20 and the dust collection box 601. The first electric push rod 602 is installed on the top of the placement plate 20 via a push rod bracket. The other end of the first electric push rod 602 is installed on the bottom of the dust collection box 601 via a push rod bracket. When the first electric push rod 602 is working, it can raise the dust collection box 601, exposing the opening of the dust collection box 601 and positioning it above the operating table 1. When the vacuum pump 605 is working, it can suck up fabric scraps and thread ends into the dust collection box 601, thereby achieving the purpose of keeping the operating table 1 clean and tidy.

[0048] The fine-tuning mechanism includes a miniature electric push rod 27. A locking plate 26 is movably connected to the tooth frame 28 via a pin. The miniature electric push rod 27 is movably connected to the tooth frame 28 via a fixing component and a pin. The other end of the miniature electric push rod 27 is movably connected to the locking plate 26 via a fixing component and a pin. A feed tooth 24 is detachably connected to the locking plate 26 via a fixing bolt. The teeth of the feed tooth 24 pass through an opening slot 25 on the needle plate 5 and are located outside the needle plate 5. The needle plate 5 is fixed to the operating table 1 via a needle plate fixing screw. Under the action of the miniature electric push rod 27 and the first infrared sensor 22, the miniature electric push rod 27 can adjust the front and back position of the feed tooth 24 to avoid the fabric shifting during sewing due to the unevenness of the feed tooth 24.

[0049] The measuring mechanism 4 includes a connecting frame 402, which is welded to the bottom of the operating table 1. A rectangular groove 408 is provided on one side of the connecting frame 402, and a connecting rod is slidably connected in the rectangular groove 408. A first mounting bracket 405 is welded to one end of the connecting rod. The shape of the first mounting bracket 405 is as follows: Figure 7 As shown, a second motor 407 is embedded in the connecting frame 402. The output shaft of the second motor 407 is connected to a threaded rod 406 via a coupling. The threaded rod 406 is threadedly connected to a threaded hole on the first mounting frame 405. A second electric push rod 404 is mounted on the top of the first mounting frame 405 via a push rod bracket. The top of the second electric push rod 404 is fixedly connected to a second mounting frame 403 via a push rod bracket. A second infrared sensor 401 is embedded in the second mounting frame 403. Based on the value measured by the second infrared sensor 401, the left and right positions of the foot are judged to ensure that the sewing needle is always located in the center of the feed dog 24. This avoids the situation where the sewing needle is not in the center of the feed dog 24 due to the presser foot shift, which would cause the fabric to shift during sewing. It also avoids the time wasted by the worker stopping to adjust the fabric due to the shift.

[0050] The fabric anti-deviation mechanism 29 includes a guide rail 292, which is integrally welded to the bottom of the operating table 1. A guide plate 291 is slidably connected inside the guide rail 292. An L-shaped frame 296 is fixedly connected to the bottom of the guide plate 291. The L-shaped frame 296 has a threaded hole, and a threaded post 295 is threaded into the threaded hole. A rotating shaft is welded to one end of the threaded post 295, and a bearing is movably inserted at one end of the rotating shaft. A fixing block 294 is embedded in the outer periphery of the bearing. The fixing block 294 and the L-shaped frame 296 are connected by an elastic plate. The elastic plate is not in the... Figure 12As shown, a fabric clamping plate 293 is fixedly connected to one side of the fixing block 294. The fabric clamping plate 293 is a rectangular plate with multiple fabric placement slots. Multiple layers of fabric can be placed in the fabric placement slots on the fabric clamping plate 293 to further limit the position of the fabric, prevent the fabric from going off-center during sewing, and eliminate the need for manual alignment, thus improving the efficiency of fabric alignment.

[0051] The specific operation of the present invention is as follows: When a sewing worker uses a sewing device to sew a hat, the controller 2 controls the first motor 15 to rotate the gear 16 according to the worker's height or the most comfortable height. The gear 16 meshes with the toothed plate 17, causing the gear 16 to move along with the toothed plate 17. At the same time, the sliding block 19 slides in the first sliding groove 18, and the connecting block slides in the second sliding groove 10. The angle of the scissor frame 12 changes, thereby raising or lowering the second support plate 11. Simultaneously, the adjusting plate 9 raises or lowers the operating table 1. The operation stops when the height of the operating table 1 reaches the required height.

[0052] The first infrared sensor 22 measures the height of the front and rear ends of the feed teeth 24. When the measured heights are inconsistent, the micro electric push rod 27 works and the angle of the micro electric push rod 27 changes, which also changes the front and rear height of the feed teeth 24 fixed on the snap plate 26. After the first infrared sensor 22 measures again and finds that the front and rear distances of the feed teeth 24 are the same, the micro electric push rod 27 stops working.

[0053] Subsequently, the threaded column 295 is pulled, and the guide plate 291 slides within the guide rail 292. Sliding stops when the fabric clamping plate 293 is no longer below the operating table 1 and its position is exactly opposite the edge of the operating table 1. The number of fabric placement slots exposed corresponds to the number of fabric layers. Taking three as an example, the threaded column 295 is rotated. Under the limit of the elastic plate, the elastic plate stretches, and the threaded column 295 rotates within the bearing, causing the fabric clamping plate 293 to rise. The process stops when all three fabric placement slots are exposed. Then, one side of each of the three fabric layers is placed into one of the fabric placement slots. The three layers of fabric are placed side by side under the sewing needle, and the presser foot is pressed down. At this time, the second motor 407 works to rotate the threaded rod 406. At the same time, the first mounting bracket 405 slides in the rectangular groove 408 with the connecting rod, so that the second mounting bracket 403 is no longer located below the operating table 1. The second electric push rod 404 works to raise the second infrared sensor 401 on the second mounting bracket 403 to the designated position. The second infrared sensor 401 measures whether the presser foot is in a horizontal position. If it is not in a horizontal position, the sewing worker manually adjusts it to a horizontal position. Then, sewing begins.

[0054] Fabric scraps or thread ends generated during sewing are lifted by the controller 2 via the first electric push rod 602, which raises the dust collection box 601 so that the opening of the dust collection box 601 is exposed in the through groove 23. After reaching a suitable height, the controller stops, and then the dust pump 605 works to suck the fabric scraps and thread ends on the worktable 1 into the dust collection box 604, thereby enabling timely cleaning or collection of fabric scraps or thread ends on the worktable.
