Description

Technical Field

[0001] This invention belongs to the field of folding and sewing machine technology, and specifically relates to a fabric positioning and clamping device. Background Technology

[0002] A folding and sewing machine is an industrial sewing device mainly used for automatically folding, splicing, stitching, or hemming fabrics, non-woven fabrics, and other materials. It is commonly found on production lines in the clothing, bag, and protective equipment manufacturing industries. A placket zipper is a zipper accessory installed at the front opening of clothing (such as trousers or jackets) to enable convenient opening and closing.

[0003] In existing technologies, when processing fabrics, workers usually need to use auxiliary devices to clamp and move the fabric edges, which cannot achieve the effect of automatically positioning, clamping, and moving the fabric edges. This affects the efficiency of fabric processing, and manual clamping and moving of the fabric edges is prone to accuracy errors, leading to product quality problems after the fabric is processed. To address these issues, how to design a fabric positioning, clamping, and moving device has become a problem that we need to solve. Summary of the Invention

[0018] The front lifting and pressing fabric assembly includes two front pressing frame guide rails 11, a front pressing frame slider 12, and a front pressing frame drive cylinder 13, all fixedly installed on one side of the vertical plate in the middle of the zipper folding base plate 4. The output shaft ends of both front pressing frame drive cylinders 13 are fixedly connected to front pressing frame drive plates 14. The front lifting and pressing fabric assembly has two adjusting nuts 27, each located inside one of the two front pressing frame drive plates 14. Each adjusting nut 27 contains a front pressing frame adjusting guide rod 15. The outer walls of both front pressing frame adjusting guide rods 15 are fitted with first pressure springs 16. The bottoms of the two front pressing frame adjusting guide rods 15... Each of the two front pressure frame slider lifting plates 17 is fixedly connected to a front pressure frame slider 12, which is fixedly connected to one side of each front pressure frame slider lifting plate 17. The two front pressure frame sliders 12 are slidably connected to the outer walls of the two front pressure frame guide rails 11. The bottom of each front pressure frame slider lifting plate 17 is fixedly connected to a front pressure frame arm 18, and a pressure frame 28 is fixedly installed at the bottom of the two front pressure frame arms 18. An elastic sheet 29 is fixedly installed on the outer wall of the pressure frame 28. The rear lifting pressure cloth assembly includes a rear pressure frame drive cylinder 19 fixedly installed on one side of the vertical plate in the middle of the zipper folding base plate 4. The output shaft end of the rear pressure frame drive cylinder 19 is fixedly connected to a rear pressure frame drive plate 2. 0. Two rear pressure frame guide rails 21 are provided on both sides of the rear pressure frame drive cylinder 19. The two rear pressure frame guide rails 21 are fixedly installed on one side of the vertical plate in the middle of the zipper folding base plate 4. The outer walls of the two rear pressure frame guide rails 21 are slidably connected to the rear pressure frame sliders 22. The number of pressure adjusting nuts 27 on the rear lifting pressure cloth assembly is set to two. The two pressure adjusting nuts 27 are located inside the rear pressure frame drive plate 20. The interior of the two pressure adjusting nuts 27 is provided with a rear pressure frame pressure adjusting guide rod 23. The outer walls of the two rear pressure frame pressure adjusting guide rods 23 are sleeved with a second pressure spring 24. The bottom of the two rear pressure frame pressure adjusting guide rods 23 is fixedly connected to the rear pressure frame slider lifting plate. 25. The rear pressure frame slider lifting plate 25 is fixedly installed on the outer wall of the two rear pressure frame sliders 22. The rear pressure frame arm 26 is fixedly installed at the bottom of the rear pressure frame slider lifting plate 25. The pressure frame 28 is fixedly installed at the bottom of the rear pressure frame arm 26. The elastic sheet 29 is fixedly installed on the outer wall of the pressure frame 28. The front lifting pressure cloth assembly and the rear lifting pressure cloth assembly are both provided with pressure frames 28 and elastic sheets 29. The pressure frames 28 and elastic sheets 29 on the front lifting pressure cloth assembly and the rear lifting pressure cloth assembly are arranged in a mirror symmetrical manner. The rear pressure frame slider lifting plate 25 is located between the two front pressure frame slider lifting plates 17. The rear pressure frame arm 26 is located between the two front pressure frame arms 18. Among them, the front lifting and pressing cloth assembly and the rear lifting and pressing cloth assembly are used to press the cloth 3 together; Specifically, when the front and rear lifting and pressing cloth assemblies are needed to press the cloth 3, the front pressing frame drive cylinder 13 and the rear pressing frame drive cylinder 19 on the front and rear lifting and pressing cloth assemblies are first activated. The front pressing frame drive cylinder 13 will drive the front pressing frame slider lifting plate 17 to rise and fall through the corresponding front pressing frame drive plate 14, pressure adjusting nut 27, and front pressing frame pressure adjusting guide rod 15. This causes the front pressing frame slider lifting plate 17 to slide up or down along the outer wall of the front pressing frame guide rail 11 through the front pressing frame slider 12. The front pressing frame slider lifting plate 17 will then drive the relative front pressing frame arm 18 to lift the relative front pressing frame slider 17 to rise or fall. The corresponding pressure frame 28 and elastic sheet 29 rise or fall, and the operation of the rear pressure frame drive cylinder 19 will drive the rear pressure frame slider lifting plate 25 to rise or fall through the corresponding rear pressure frame drive plate 20, pressure adjusting nut 27, and rear pressure frame pressure adjusting guide rod 23. The rear pressure frame slider lifting plate 25 slides and rises or falls on the outer wall of the rear pressure frame guide rail 21 through the rear pressure frame slider 22, so that the front lifting and pressing cloth assembly and the rear lifting and pressing cloth assembly drive the corresponding elastic sheet 29 to rise or fall. When the elastic sheet 29 falls, it presses the cloth 3 below. After the elastic sheet 29 rises, it stops pressing the cloth 3. It should be noted that when it is necessary to press fabrics of different thicknesses, the position of the pressure adjusting nut 27 on the front lifting and pressing fabric assembly and the rear lifting and pressing fabric assembly on the corresponding front pressing frame drive plate 14 or rear pressing frame drive plate 20 can be adjusted so that the pressure adjusting nut 27 drives the connected parts to rise or fall, thereby changing the position of the elastic piece 29 after rising or falling, so as to adapt to the pressing requirements of fabrics of different thicknesses.

[0019] The transfer assembly includes a transfer motor fixing plate 5 fixedly installed on the top of the zipper folding base plate 4. A bidirectional transfer motor 6 is fixedly installed on one side of the transfer motor fixing plate 5. The output shaft end of the bidirectional transfer motor 6 passes through the transfer motor fixing plate 5 and is fixedly connected to a bidirectional transfer drive wheel 7. A transfer drive timing belt 8 is tensioned and connected to the outer wall of the bidirectional transfer drive wheel 7. The transfer drive timing belt 8 passes through the zipper folding base plate 4 and is tensioned and connected to a bidirectional transfer timing shaft 9. Two timing wheels are fixedly connected to the outer wall of the end of the bidirectional transfer timing shaft 9 through bearing seats. Two folding extension base plates 10 are fixedly connected to the left and right ends of the zipper folding base plate 4. Both folding extension base plates 10 are fixedly installed on the bottom of the zipper folding base plate 4. The bottom of each of the two folded edge extension base plates 10 is provided with a transfer guide rail 30. The outer walls of the two transfer guide rails 30 are slidably connected with two sets of transfer sliders 31. Both ends of the bidirectional transfer synchronous shaft 9 are provided with synchronous wheels. The bidirectional transfer synchronous shaft 9 is tensioned to two bidirectional moving synchronous belts 33 through the two synchronous wheels. The bottom and top of the inner walls of the two bidirectional moving synchronous belts 33 are fixedly connected with synchronous belt clamps 32 by bolts. The bottom of the two sets of transfer sliders 31 below the transfer guide rail 30 is fixedly connected with a rear folded edge positioning plate 34 and a front folded edge positioning plate 35 respectively. The synchronous belt clamps 32 at the bottom and top of the inner walls of the bidirectional moving synchronous belts 33 are fixedly connected to the rear folded edge positioning plate 34 and the front folded edge positioning plate 35 respectively. The repositioning component is used to avoid the sewn fabric 3 so that the sewn fabric 3 with zipper can be removed. Specifically, when it is necessary to remove the sewn fabric 3, the bidirectional transfer motor 6 can be activated. The bidirectional transfer motor 6 drives the bidirectional transfer synchronous shaft 9 to rotate through the bidirectional transfer drive wheel 7 and the transfer drive synchronous belt 8. This causes the bidirectional transfer synchronous shaft 9 to move the two synchronous belt clamps 32 on it closer or further apart through the synchronous wheel and the bidirectional transfer synchronous belt 33. The synchronous belt clamps 32 then move the corresponding hem positioning discs 34 closer or further apart. The hem positioning discs 34 then move the corresponding transfer sliders 31 along the outer wall of the transfer guide rail 30 to ensure smooth operation. When the synchronous belt clamps 32 move the corresponding hem positioning discs 34 and 35 further apart, an opening is formed between the two hem positioning discs 34 and 35, allowing the worker to remove the sewn fabric 3. When the synchronous belt clamps 32 move the corresponding hem positioning discs 34 closer together, the hem positioning discs 34 and 35 reset and close the opening, allowing for the reprocessing of the new fabric 3.

[0020] The fabric positioning assembly includes a positioning piece 36 on the top of a rear folding positioning plate 34 and a front folding positioning plate 35. The top of both the rear folding positioning plate 34 and the front folding positioning plate 35 is provided with a positioning groove for the positioning piece 36 to slide. Both ends of the positioning piece 36 are fixedly connected to a drive arm 37. The end of the drive arm 37 away from the corresponding positioning piece 36 is bent upward. The outer wall of the bent part of the drive arm 37 away from the corresponding positioning piece 36 is fixedly connected to the output shaft of a positioning telescopic cylinder 38. A limiting angle plate 39 is fixedly installed on one side of the positioning telescopic cylinder 38. The positioning telescopic cylinder 38 and the limiting angle plate 39 are fixedly installed on the top of the corresponding rear folding positioning plate 34 or front folding positioning plate 35. The drive arm 37 and the limiting angle plate 39 are provided with a limiting screw 40 inside. The positioning component is used to position the fabric 3, move it to the side and back it, so as to achieve a neat and straight edge. Specifically, when fabric 3 needs to be positioned and folded, fabric 3 is pressed by the elastic plates 29 of the front and rear lifting and clamping fabric assemblies above the rear folding positioning plate 34, the front folding positioning plate 35, and the positioning piece 36. The positioning telescopic cylinders 38 on the top of the rear folding positioning plate 34 and the front folding positioning plate 35 will push the corresponding positioning piece 36 to slide along the inside of the positioning groove through the corresponding drive arms 37, so that the two positioning pieces 36 move closer or further apart. When the two positioning pieces 36 move closer together, the positioning piece 36 can act as a positioning edge for fabric 3, ensuring that the fabric edge is flat, so as to achieve the effect of positioning and flattening the fabric 3 for folding. Fabric 3 is pressed by the elastic plates 29 of the lifting and clamping fabric assembly, and the fabric pulling assembly pulls the fabric 3 to After the lower part of the positioning piece 36, the front and rear fabric clamping assemblies clamp the fabric edge folded under the positioning piece 36 under the positioning piece 36 through the fabric clamping drive cylinder and drive assembly. When the rear folding edge positioning plate 34 and the front folding edge positioning plate 35 feed the folded fabric into the sewing machine, the telescopic cylinder 38 can drive the corresponding two positioning pieces 36 to move away from each other and reset to avoid starting the sewing needle through the corresponding drive arm 37. At this time, the retraction distance of the positioning piece 36 is determined by the limiting angle plate 39. When the folding edge of the fabric 3 is large, the limiting angle plate 39 can be adjusted to leave more retraction space. When the folding edge of the fabric 3 is small, the limiting angle plate 39 can be adjusted to leave less retraction space to adapt to different folding edge requirements of the fabric 3.

[0021] The rear fabric clamping assembly includes a rear fabric edge clamping plate 41 located at the bottom of the rear folding positioning plate 34, and the front fabric clamping assembly includes a front fabric edge clamping plate 42 located at the bottom of the front folding positioning plate 35. Soft sponges 43 are fixedly connected to the working surfaces of both the rear fabric edge clamping plate 41 and the front fabric edge clamping plate 42. Reinforcing strips 44 and rotating reinforcing strips 47 are fixedly attached to the top of both the rear fabric edge clamping plate 41 and the front fabric edge clamping plate 42. Multiple reinforcing strips 44 are provided, and each reinforcing strip 44 has a sliding head 45 at its top. The sliding head 45 has an internal opening for... The ramp chute 46 and the soft sponge 43 are fixedly connected to the top of the rear fabric edge clamp 41 and the front fabric edge clamp 42 at a position close to each other. The rotating reinforcing strip 47 is fixedly connected to the side of the rear fabric edge clamp 41 and the front fabric edge clamp 42 away from each other. The rotating reinforcing strip 47 has four slots inside, and each of the four slots is rotatably connected to an elastic top bead 48. The bottom of the front folding edge positioning plate 35 and the rear folding edge positioning plate 34 are both provided with fabric edge clamp receiving layers 54 to accommodate the rear fabric edge clamp 41 and the front fabric edge clamp 42. The selvage plate receiving layer 54 has a reinforcing strip groove 55 inside, which corresponds to the size and number of reinforcing strips 44. The reinforcing strip groove 55 has a through hole for the sliding head 45 to pass through. The part of the selvage plate receiving layer 54 that connects the rotating reinforcing strip 47 and the elastic top bead 48 has a square hole for the rotating reinforcing strip 47 to be inserted and a round hole for the elastic top bead to be inserted. The square hole and the round hole are used to assist the rotating reinforcing strip 47 and the elastic top bead 48 in rotating connection with the rear end of the selvage plate receiving layer 54.

[0022] The rear clamping plate drive assembly includes a rear clamping plate drive plate 50 disposed on the top of the rear folding positioning plate 34, and the front clamping plate drive assembly includes a front clamping plate drive plate 49 disposed on the top of the front folding positioning plate 35. Both the front clamping plate drive plate 49 and the rear clamping plate drive plate 50 are provided with clamping plate drive rods 51 and clamping plate drive spherical connectors 52. After multiple sliding heads 45 pass through the corresponding rear clamping plate drive plate 50 or front clamping plate drive plate 49, a ramp groove 46 is opened at the higher part. The clamping plate drive rods 51 are inserted into the inside of the ramp groove 46. The output shafts of clamping plate drive cylinders 53 are fixedly connected to the side of the clamping plate drive spherical connectors 52 disposed on the rear clamping plate drive plate 49 and the front clamping plate drive plate 49 that are far apart from each other. The two clamping plate drive cylinders 53 are respectively fixedly installed on the top of the rear folding positioning plate 34 and the front folding positioning plate 35. Among them, the front and rear fabric clamping components and the front and rear fabric clamping drive components are used to clamp and fix the folded edge of the fabric 3 so that the fabric 3 can be sewn. Specifically, when it is necessary to clamp and fix the folded edge of fabric 3, firstly, start the clamping plate drive cylinder 53, so that the clamping plate drive cylinder 53 pulls the clamping plate drive plate 49 and the clamping plate drive rod 51 to move through the clamping plate drive spherical connector 52. The clamping plate drive rod 51 moves along the inclined groove 46 inside the sliding head 45, so that the clamping plate drive rod 51 drives the sliding head 45 to rise or fall through the inclined groove 46. When the sliding head 45 rises or falls, the sliding head 45 will drive the fabric edge clamping plate 41 to rotate around the rotation center of the elastic top bead 48 and the folding edge positioning plate 34 through the reinforcing strip 44, so that the fabric edge clamping plate 41 performs a fan-shaped clamping operation, and the fabric edge clamping plate 41 cooperates with the folding edge positioning plate 34 to clamp and fix or loosen the folded edge of fabric 3.

[0023] Working principle: First, the fabric 3 is positioned by the feeding and positioning component.
