Description

Technical Field

[0001] This utility model relates to the field of sewing machine accessories technology, and more specifically to a hemming assembly for a cuff sewing machine. Background Technology

[0002] A cuff sewing machine is a specialized sewing device used to process cuffs. It is commonly used in the garment manufacturing industry, and cuff sewing machines are used to hem the cuffs of garments.

[0003] like Figure 1 As shown, the cuff sewing machine includes a worktable, a tubing mechanism, a mounting base 2a mounted on the worktable, a sewing machine body 3a mounted on the mounting base 2a, roller devices and a correction device rotatably mounted on both sides of the sewing machine body 3a, and a hemming assembly mounted on the side of the sewing machine body 3a. The roller device includes two rollers 4a arranged side by side and a roller drive motor for driving the two rollers 4a to rotate. The two rollers 4a are rotatably mounted on the mounting base 2a. The correction device includes a correction element 5a and a correction drive motor for driving the correction element 5a to rotate. The correction element 5a is rotatable. The garment is mounted on the mounting base 2a, wherein the two rollers 4a and the correction element 5a together form the sleeve spreading area; the hemming assembly includes a fixed plate 61a fixedly mounted on the sewing machine body 3a and a sliding plate 62a located on the lower side of the fixed plate 61a, a hemming gap is formed between the fixed plate 61a and the sliding plate 62a, the first pipe 7a in the pipe mechanism is directly opposite the hemming gap, the upper side of the fixed plate 61a is connected to the table surface of the sewing machine body 3a and the correction element 5a respectively, and the sliding plate 62a is mounted on the mounting base 2a in a manner that allows it to move along the width direction of the worktable.

[0004] When the sleeve is placed between the two rollers 4a and the correction component 5a, the hem rolling assembly is located inside the sleeve, and the cuff of the sleeve hangs down naturally. Then, the sliding plate 62a moves to the air blowing hole near the first pipe 6a. At this time, the cuff of the sleeve hangs down to the upper side of the sliding plate 62a. Then, the air blowing hole of the first pipe 7a blows air, causing the sleeve to be rolled up through the hem rolling gap.

[0005] The above structure can be used to hem the sleeves. The hem assembly is installed on the side wall of the sewing machine body 3a near the correction component 5a. However, since the fixing plate 61a is a plate-shaped structure and has a large volume, the overall volume of the hem assembly is also large. As a result, the correction component 5a needs to be translated in a direction away from the sewing machine body 3a in order to leave enough space for the hem assembly. This results in the overall structure of the machine not meeting the requirement of compactness.

[0006] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0036] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0037] A cuff sewing machine hemming assembly is installed in existing conventional cuff sewing machines. In addition, this utility model can also be installed in neckline sewing machines and hem sewing machines.

[0038] like Figure 1 As shown, a conventional cuff sewing machine can be a commercially available cuff sewing machine. For example, the cuff sewing machine includes a worktable 1a, a tubing mechanism, a mounting base 2a mounted on the worktable 1a, a sewing machine body 3a fixedly mounted on the mounting base 2a, and roller devices and a correction device rotatably mounted on both sides of the sewing machine body 3a. The roller device includes two mating rollers 4a and a roller drive motor for driving one of the rollers 4a to rotate. The two rollers 4a are rotatably mounted on the mounting base 2a. The correction device includes a correction element 5a and a correction drive motor for driving the correction element 5a to rotate. The correction element 5a is rotatably mounted on the mounting base 2a. The two rollers 4a and the correction element 5a together form the sleeve opening area. The tubing mechanism is arranged in a conventional manner.

[0039] Furthermore, the aforementioned cuff sewing machine can also employ other conventional cuff sewing machines, such as the cuff sewing machine disclosed in Chinese Patent Publication No. CN222861818U, which describes a cuff and neckline feeding mechanism for a sewing machine.

[0040] The improvement of this utility model lies in the improved structure and installation position of the rolled edge assembly, such as... Figure 2 As shown - Figure 6 As shown, the hemming assembly includes a push cylinder 1, a fixing member 2, and a sliding assembly 3. The sliding assembly 3 includes a long side section 31 and a U-shaped mating section 32. The opening of the mating section 32 faces the long side section 31, and the lower side of the mating section is directly mounted or detachably mounted on the first end of the long side section. The piston rod 11 of the push cylinder 1 is connected to the second end of the long side section 31, and the axis of the push cylinder 1 is in the same direction as the arrangement of the long side section 31. The fixing member 2 is located on the upper side of the mating section 32, and a hemming gap is formed between the fixing member 2 and the mating section 32.

[0041] For ease of description, the position of the mating section 32 is taken as the front side, and the opposite side is taken as the rear side. That is, the width direction of the workbench 1 is the front-to-back direction, and the horizontal direction perpendicular to the front-to-back direction is the left-to-right direction. In this embodiment, the correction device is located on the right side of the sewing machine body 3a, and the roller assembly is located on the left side of the sewing machine body 3a.

[0042] Specifically, the cylinder body of the aforementioned push cylinder 1 is fixedly installed on the table surface of the sewing machine body 3a, and the push cylinder 1 is arranged in the front-back direction. The piston rod 11 of the push cylinder 1 is located on the front side of the cylinder body of the push cylinder 1. In this embodiment, the push cylinder 1 is a cylinder that is already available on the market. In this embodiment, the installation structure of the push cylinder 1 is as follows: a cylinder mounting plate 13 is fixedly installed on the table surface of the sewing machine body 3a. An L-shaped cylinder fixing plate 131 is fixedly installed on the cylinder mounting plate 13. The cylinder fixing plate 131 has a through hole for the piston rod 11 of the push cylinder 1 to pass through. The front end of the cylinder body 12 of the push cylinder 1 and the cylinder fixing plate 131 are fixedly installed together. The two can be assembled in a conventional way. For example, the front end of the cylinder body of the push cylinder 1 is provided with a threaded section, and the cylinder body 12 passes through the through hole and is tightly screwed to the front end of the cylinder body of the push cylinder 1 by a fixing nut. At this time, the rear side of the cylinder fixing plate 131 abuts against the cylinder body 12 of the push cylinder 1, thereby realizing the assembly of the cylinder body of the push cylinder 1.

[0043] Furthermore, the transmission structure between the piston rod 11 of the pushing cylinder 1 and the long side section 31 can adopt a conventional transmission structure. For example, the rear end of the long side section 31 extends upward to a mounting part 311, which has a through hole through which the piston rod 11 of the pushing cylinder 1 passes. The piston rod 11 of the pushing cylinder 1 has threaded sections on both sides corresponding to the mounting part 311, and fixing nuts are tightly screwed into the two threaded sections to fix the piston rod 11 of the pushing cylinder 1 on the mounting part 311. In this way, when the piston rod 11 of the pushing cylinder 1 extends, it drives the long side section 31 to move forward; when the piston rod 11 of the pushing cylinder 1 retracts, it drives the long side section 31 to move backward.

[0044] Preferably, to ensure that the long side segment 31 slides smoothly, a slide rail 331 is fixedly installed on the upper side of the cylinder mounting plate 13. The slide rail 331 is arranged in the front-back direction, and a slider 332 is fixedly installed on the lower side of the rear end of the long side segment 31. The slide rail 331 and the slider 332 slide in cooperation, so that when the long side segment 31 slides forward or backward, the long side segment 31 slides along the slide rail 331.

[0045] The aforementioned mating section 32 is installed on the long side section 31 in such a way that the distance between its rear side and the front end face of the long side section 31 can be adjusted. Specifically, the front end of the long side section 31 is located in the mating section 32 in the sliding assembly 3. A strip hole 41 is provided on the lower side of the mating section 32. The strip hole 41 is arranged in the front-back direction. A mounting hole 42 is provided on the front end of the long side section 31. The strip hole 41 and the mounting hole 42 correspond to each other, and the mounting hole 42 is equipped with a locking component. This locking component adopts a conventional locking component, such as a locking component including a screw-fitted bolt and nut. In this way, during assembly, the position of the mating section 32 on the long side section 31 is determined, that is, the size of the adjustment distance is increased or decreased. Then, the bolt is passed through the mounting hole 42 and the strip hole 41 in sequence, and then the nut is screwed into the bolt, so that the mating section 32 and the long side section 31 can be installed and fixed. Preferably, to ensure stable installation between the mating section 32 and the long side section 31, there are two mounting holes 42. The two mounting holes 42 are arranged sequentially along the length of the long side section 31, and both mounting holes 42 correspond to the strip hole 41. Each of the two mounting holes 42 is equipped with a locking component, that is, there are two locking components, and the locking components adopt the aforementioned structure.

[0046] The aforementioned fastener 2 includes a fixing plate 21 and a fixing mounting part 22. The fixing mounting part 22 is formed by extending downward from the middle of the front side of the fixing plate 21, i.e., the fixing mounting part 22 is arranged vertically. The right side of the fixing plate 21 is a sloping side 211, which is arranged sloping upward from right to left and is suspended. The sloping side 211 is connected to the aforementioned straightening member 5a to guide the clothing. Preferably, an extension part 321 is formed by extending from the left side of the upper side of the mating section 32. The fixing plate 21 is integrally connected to the extension part 212. The extension part 321 and the extension part 212 correspond to each other, thereby increasing the support area of ​​the clothing in the middle position.

[0047] The sewing machine body 3a has a mounting plate 51 fixedly installed on its table surface corresponding to the right side of its sewing needle. The fixing member 2 and the sliding component 3 are both installed on the mounting plate 51. Specifically, the rear side of the mounting plate 51 extends to the rear side of the sewing machine body 3a's table surface, and the right side of the mounting plate 51 matches the right side of the sewing machine body 3a's table surface. The front side of the mounting plate 51 extends out of the front side of the sewing machine body 3a's table surface. The cylinder body 12 of the push cylinder 1 is fixedly installed on the rear side of the mounting plate 51 in the aforementioned manner. That is, the cylinder body 12 of the push cylinder 1 is indirectly installed on the sewing machine body 3a's table surface through the mounting plate 51. At this time, the long side segment 31 is arranged close to the right side of the mounting plate 51 to minimize the distance between it and the sewing machine body 3a, so as to facilitate the subsequent retraction of the correction component 5a.

[0048] Furthermore, a connecting plate 52 is fixedly installed on the front side of the aforementioned mounting plate 51. The connecting plate 52 is L-shaped. Preferably, the fastener 2 is installed on the connecting plate 52 in a manner that allows adjustment of the rolled edge gap. More specifically, the fixed mounting part 22 has a strip-shaped hole 43, which is arranged in the vertical direction. The connecting plate 52 has a mounting hole 44, which corresponds to the strip-shaped hole 43. The mounting hole 44 is equipped with a locking component, which is the same as the aforementioned locking component. Preferably, there are two strip-shaped holes 43 and two mounting holes 44. The two strip-shaped holes 43 are arranged side by side, and they are arranged sequentially from left to right. The two mounting holes 44 and the two strip-shaped holes 43 correspond one-to-one. The two mounting holes 44 are equipped with the aforementioned locking components to ensure the stability of the mounting structure of the connecting plate 52. In this way, by adjusting the position of the fixed mounting part 22 relative to the connecting plate, that is, by slightly moving the fastener 2 up or down within the range of the second strip hole 43, the rolled edge gap between the lower side of the fastener 2 and the upper side of the mating section 32 is changed. Then, the bolts are inserted into the second mounting hole 44 and the second strip hole 43 in sequence, and the nuts are screwed into the bolts, so that the fastener 2 can be fixedly installed on the connecting plate 52.

[0049] In a preferred embodiment, the connecting plate 52 is mounted on the table surface of the sewing machine body 3a in a manner that allows it to move slightly forward or backward relative to the table surface of the sewing machine body 3a. Specifically, the connecting plate 52 has strip-shaped holes 45 arranged in the front-to-back direction, and the mounting plate 51 has mounting holes 46 corresponding to the strip-shaped holes 45. The mounting holes 46 are equipped with locking components, which are the same as those described above. Preferably, there are two strip-shaped holes 45 and two mounting holes 46, with each pair of strip-shaped holes 45 and mounting holes 46 corresponding one-to-one, and each of the two mounting holes 46 is equipped with the aforementioned locking components. Thus, when the connecting plate 52 moves forward or backward, the fixing member 2 moves forward or backward as a whole. Then, bolts are inserted sequentially into the strip-shaped holes 45 and mounting holes 46, and then nuts are screwed into the bolts to complete the assembly. Preferably,

[0050] This embodiment provides a hemming assembly for a cuff sewing machine. The assembly section 32 can be adjusted forward or backward relative to the long side section 31, the connecting plate 52 can be slightly adjusted forward or backward relative to the sewing machine body 3a, and the fixing member 2 can be slightly adjusted upward or downward relative to the connecting plate 52. This allows the operator to flexibly adjust the machine according to the actual situation.

[0051] Furthermore, in the aforementioned pipeline mechanism, one of the pipelines extends to the rear side of the mating section 32, and the air blowing hole of the pipeline is directly opposite the crimped gap. The sliding component moves backward under the retraction of the piston rod 11 of the pushing cylinder 1 until the rear side of the mating section 32 is close to the air blowing hole of the pipeline.

[0052] This utility model discloses a hemming assembly for a cuff sewing machine. The specific hemming method is as follows: Taking a garment sleeve as an example, the sleeve is fitted between the roller and the guide component 5a of the cuff sewing machine. At this time, the cuff of the sleeve hangs down naturally. Then, the piston rod 11 of the cylinder 1 is pushed back, so that the fixing component 2 and the sliding component 3 move backward as a whole until the mating section 32 on the fixing component 2 is close to the air hole of the corresponding pipe. The air hole of the pipe is always directly facing the hemming gap. Then, air is blown from the air hole of the corresponding pipe so that the naturally hanging part of the garment is blown into the hemming gap. Then, the needle of the sewing machine body 3a begins to sew. At the same time, the guide component 5a and the roller continuously drive the garment to make a circular motion, thereby realizing the hemming and sewing of the cuff of the sleeve.
