Technical Field

[0001] This invention relates to the field of garment processing equipment technology, and specifically to a sewing method based on garment-specific clamps. Background Technology

[0002] The garment manufacturing process includes design, cutting, sewing, sizing, and packaging. During cutting and sewing, clamps are needed to hold fabric pieces, such as cuffs, in place for easier cutting and sewing. Existing clamps are typically fixed structures, unable to extend or retract, and can only hold single-length pieces of fabric, limiting their application. To address this issue, Chinese Patent Application No. 201810842782.1, published on November 20, 2018, discloses a processing clamp for producing garment cuffs. This invention relates to the field of garment production machinery technology and includes a clamping platform, with a first... A clamping device is described, with a second clamp fixedly connected to the other end of the upper surface of the clamping platform. A slider is fixedly connected to the middle of the lower surface of the first clamp. A rotating rod is installed inside the clamping platform, with a driven wheel fixedly connected to one end of the rotating rod and a driving wheel on one side of the driven wheel. A cuff clip is fixedly connected to one end of the upper surface of the second clamp, and a button is installed at the other end of the upper surface of the second clamp. A pressing rod is fixedly connected to the middle of the lower surface of the button, with a pressure bar on one upper side of the pressing rod and a triangular locking block fixedly connected to the lower lower side of the pressing rod. A spring is installed at the bottom of the pressing rod, which can extend and retract according to the length of the garment piece, thereby better clamping the garment piece. It has a wide range of applications and is easy to use. This document describes a method of fixing and pressing the fabric with processing clamps at both ends, and then tightening the fabric by moving the clamps, which is convenient for processing and production. However, after the fabric is clamped by the processing clamps, it cannot be moved, which is inconvenient when other processes such as sewing are required, thus affecting the production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a sewing method based on a garment-specific clamp. After the fabric is clamped by the garment-specific clamp, the fabric can be moved to facilitate sewing, thereby effectively improving production efficiency and sewing precision.

[0004] To achieve the above objectives, a sewing method based on a garment-specific clamp is provided. The garment-specific clamp includes a mounting frame, a movable device fixedly mounted on one end of the mounting frame, and a clamping device slidably connected to the mounting frame. Both ends of the movable device are connected to the inner side of the mounting frame, the front end of the mounting frame is connected to an extension table, and the other end of the mounting frame is provided with a first elastic element. The mounting frame is connected to the clamping device through the first elastic element, the movable device is connected to the clamping device, and the clamping device can move within the mounting frame.

[0005] The clamping device includes a carriage, a clamping plate, and a lifting drive. The clamping plate is slidably connected to the mounting frame, and the carriage is located above the clamping plate. The carriage is connected to the clamping plate via the lifting drive.

[0006] The specific steps include:

[0007] Step (1) When needed, install the garment-specific clamp onto the sewing equipment and use the extension table as the base of the sewing equipment; fold the fabric to be sewn according to the processing requirements, and then place one side of the fabric on the clamp.

[0008] Step (2) Start the lifting drive to lower the carriage and press the fabric onto the clamp.

[0009] Step (3) Use the moving device to make the clamping device slide left and right on the mounting frame to move the fabric, and use the sewing equipment to sew the fabric.

[0010] Step (4) After the fabric processing is completed, the clamping device is reset under the action of the first elastic element.

[0011] The above configuration, by incorporating a moving device and a first elastic element inside the mounting frame, connects the mounting frame to the clamping device via the first elastic element, and the moving device is slidably connected to the clamping device. This allows the moving device to drive the clamping device to move within the mounting frame, and after movement, it can be reset by a first spring, facilitating the processing of the clamped fabric and thus improving production efficiency. By connecting the front end of the mounting frame to the extension table, it is easy to place the fabric on the extension table, facilitating sewing and improving production efficiency. The inclusion of a slide, clamping plate, and lifting drive facilitates the clamping of the fabric. The clamping device holds the fabric, and the translation of the clamping device enables sewing, thus improving sewing precision.

[0012] Furthermore, the moving device includes a turntable, a winding roller, and a steel wire rope. The turntable is rotatably mounted on the mounting frame, and a push rod is provided at the edge end of the turntable. The winding roller is rotatably mounted at one end of the mounting frame, and the turntable is connected to one end of the winding roller through a connecting shaft. One end of the steel wire rope is connected to the winding roller, and the other end of the steel wire rope is connected to the clamping plate.

[0013] In step (3), the turntable is rotated by manually pushing the push rod, which in turn drives the winding roller to rotate, thereby shrinking the wire rope and allowing the clamping device to slide on the mounting frame. In this way, the turntable can be rotated by pushing the push rod, thereby rotating the winding roller and shrinking the wire rope.

[0014] Furthermore, the outer surface of the winding roller is provided with a take-up groove for winding up and unwinding the wire rope, and one end of the wire rope is fixedly set at one end of the take-up groove; when the winding roller rotates, the wire rope is wound in the take-up groove.

[0015] The above setup involves setting a take-up groove on the outer surface of the winding roller and fixing a steel wire rope at one end of the take-up groove, allowing the steel wire rope to be wound onto the take-up groove in a regular manner.

[0016] Furthermore, the lifting drive includes a drive motor, a threaded rod, and a threaded sleeve. The drive motor is mounted on the sliding frame, the threaded rod is connected to the output shaft of the drive motor, and the threaded sleeve is fixedly mounted on the clamping plate. The threaded rod and the threaded sleeve are threadedly connected. An anti-rotation device is provided between the clamping plate and the sliding frame. When the drive motor operates clockwise, it drives the threaded rod to rotate. Under the action of the threaded rod and the threaded sleeve, the sliding frame moves downward and clamps the fabric together with the clamping plate. When the drive motor operates counterclockwise, it drives the threaded rod to rotate in the opposite direction, which in turn drives the sliding frame to rise. This facilitates the lifting and lowering of the sliding frame, making it convenient to clamp and release the fabric, and ensuring reliable fabric clamping.

[0017] Furthermore, a limiting disc is provided at the bottom of the threaded sleeve to restrict its rotation. The limiting disc is located inside the bottom of the clamping plate, and a rotating groove is provided at a position corresponding to the limiting disc inside the bottom of the clamping plate. The limiting disc is placed in the rotating groove, and the threaded sleeve passes through the clamping plate. Bolts or pressure plates are provided at the bottom of the clamping plate to press the limiting disc. This can better restrict the rotation of the threaded sleeve.

[0018] Furthermore, the sliding frame includes a top plate and a pressure ring disposed on the lower edge of the top plate. When clamping the fabric, the pressure ring and pressure plate work together to hold the fabric in place. The fabric can be clamped by the action of the pressure ring and the clamping plate.

[0019] Furthermore, the anti-rotation device includes a first connecting seat, a second connecting seat, a connecting arm, and a slide rod; the first connecting seat is mounted on the clamping plate, and a slide rod is provided inside the pressure ring, with the axis of the slide rod parallel to the top surface of the clamping plate; the second connecting seat is slidably mounted on the slide rod on both sides of the lifting drive; a connecting arm is hinged between the first connecting seat and the second connecting seat; the height of the first connecting seat, the height of the second connecting seat, the width of the connecting arm, and the diameter of the slide rod are all less than the height of the pressure ring;

[0020] In step (2), as the lifting drive drives the slide to move downward, the connecting arm pushes the second connecting seat to slide outward along the slide rod.

[0021] With the above configuration, the carriage is supported by the connecting arm during descent or ascent. This not only prevents the carriage from rotating and ensures its descent and ascent, but also provides good stability during descent or ascent.

[0022] Furthermore, a second spring is fitted on the slide rod between the second connecting seat and the pressure ring. When the connecting arm pushes the second connecting seat to slide outward along the slide rod, it compresses the second spring. By setting the second spring, the elasticity of the second spring can generate a buffering force on the outward movement of the second connecting seat. This buffering force can be transmitted to the carriage, thereby buffering the descent of the carriage and making the descent of the carriage more stable. In addition, the second spring makes it easier for the second connecting seat to return to its original position, thereby saving energy for the lifting drive.

[0023] Furthermore, sliding grooves are provided on both the front and rear sides of the mounting frame, and sliders that slide in cooperation with the sliding grooves are provided on both sides of the clamping plate; the clamping device slides along the sliding grooves under the action of the sliders. This guides the translation of the clamping device.

[0024] Furthermore, the top surface of the mounting bracket, the top surface of the extension platform, and the top surface of the clamping plate are located in the same plane. This facilitates the placement and sewing of the fabric. Attached Figure Description

[0026] Figure 2 This is a schematic diagram of the overall structure from another perspective of the present invention.

[0027] Figure 3 This is a partial cross-sectional view of the present invention.

[0028] Figure 4 This is a flowchart of the process of the present invention. Detailed Implementation

[0029] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation details.

[0030] like Figure 1-3As shown, this embodiment of the invention provides a sewing method based on a garment-specific clamp. The garment-specific clamp includes a mounting frame 1, a cavity 100 within the mounting frame 1, a moving device 4 fixedly mounted at one end of the mounting frame 1, and a clamping device 5 slidably mounted within the mounting frame 1. The moving device 4 includes a turntable 41, a winding roller 45, and a steel wire rope 47. The turntable 41 is located at the front end of the mounting frame 1, on the left side of the extension table 3. A push rod 48 is provided at the edge of the turntable 41, which can rotate the turntable 41 by pushing the push rod 48. The turntable 41 is connected to one end of the winding roller 45 via a connecting shaft. The winding roller 45 is mounted across the cavity at the left end of the mounting frame 1 via a bearing. The rotation of the turntable 41 drives the winding roller 45 to rotate. A take-up groove 46 is provided on the outer surface of the winding roller 45. One end of the steel wire rope 47 is fixedly mounted on the take-up groove 46. The rotation of the turntable 41 drives the winding roller 45 and the take-up groove 46 to rotate together, thereby realizing the take-up and unwinding of the steel wire rope 47.

[0031] like Figure 1-2 As shown, the front end of the mounting bracket 1 is connected to the extension table 3, and the top surface of the mounting bracket 1 and the top surface of the extension table 3 are located in the same plane, thus facilitating the more flat placement of the fabric on the extension table; as Figure 3 As shown, in this embodiment, the clamping device 5 includes a slide 512, a lifting drive, and a clamping plate 511. The lifting drive includes a drive motor 51, a threaded rod 52, and a threaded sleeve 56. The slide includes a top plate 512 and a pressure ring 513 disposed on the lower edge of the top plate. Slider blocks 43 are respectively disposed on the front and rear sides of the clamping plate 511, and the sliders 43 are slidably connected to the slide grooves 44. Slide grooves 44 are respectively provided at the front and rear ends of the mounting frame 1. The top surface of the clamping plate 51 is in the same plane as the top surface of the mounting frame, which facilitates placement. The fabric is placed and sewn, while the other end of the slider 43 is fixedly connected to the steel wire rope 47. One end of the clamping plate 511 is fixedly connected to one end of the first elastic element, which is the first spring 42. The other end of the first spring 42 is fixedly connected to the inner side of the mounting frame 1. This allows the slider 43 to slide in the slide groove 44 through the contraction of the steel wire rope 47, thereby driving the clamping device 5 to move within the mounting frame 1. At the same time, the first spring 42 can be reset, thereby improving production efficiency.

[0032] like Figure 3As shown, the threaded sleeve 56 passes through the clamping plate 511. The threaded sleeve 56 has threads that match those of the threaded rod 52. A limiting plate 58 is provided at the bottom of the threaded sleeve 56 to restrict its rotation. A rotating groove 57 is provided at a position corresponding to the limiting plate 58 on the clamping plate 511. The rotating groove 57 has a square cross-sectional shape. The limiting plate 58 is disposed within the rotating groove 57. The limiting plate 58 is fixed by screws or pressed by a pressure plate to prevent it from detaching from the clamping plate. The drive motor... The machine 51 is fixedly mounted on the top of the top plate 512. The top plate 512 has a through hole. One end of the threaded rod 52 passes through the through hole and is connected to the output end of the drive motor 51. The other end of the threaded rod 52 is connected to the threaded sleeve 56. Below the top plate 512, a slide rod 53 is fixed to the pressure ring 513. The pressure ring 513 is annular and forms an accommodating space. The slide rod 53 is located in the accommodating space. The bottom surface of the pressure ring 513 is lower than the lowest point of the slide rod 53. The axis of the slide rod 53 is parallel to the top surface of the clamping plate. A first connecting seat 510 is fixed on the clamping plate 511. Second connecting seats 55 are slidably sleeved on the slide rod 53 on both sides of the threaded rod 52. A connecting arm 59 is hinged between the first connecting seat 510 and the second connecting seat 55. A second spring 54 is sleeved on the slide rod 53 between the pressure ring 513 and the second connecting seat 55. The drive motor 51 rotates, causing the threaded rod 52 to rotate, thereby raising or lowering the slide. During the lowering process, the slide presses the fabric firmly, making the slide 512 more stable during lifting and lowering, thus improving its practicality. Furthermore, by incorporating a second spring, the spring force can buffer the outward movement of the second connecting seat. This buffering force can be transmitted to the slide, thus buffering the descent of the slide and making the descent more stable. Additionally, the second spring makes it easier for the second connecting seat to return to its original position, thereby saving energy in the lifting drive.

[0033] like Figure 4 As shown, in this embodiment, the specific steps of a working method based on a garment-specific clamp include:

[0034] (1) When needed, install the garment-specific clamp onto the sewing equipment, use the extension table 3 as the base of the sewing equipment, fold the fabric to be sewn according to the processing requirements, and then place one side of the fabric on the clamp 511.

[0035] (2) Start the drive motor 51, drive the threaded rod 52 to rotate. The threaded rod 52 cooperates with the threaded sleeve 56, so that the threaded rod 52 rotates and moves downward. At the same time, the connecting arm 59 pushes the second connecting seat 55 to slide in the length direction of the slide rod, so that the second spring 54 is compressed, making the lifting process more stable. Finally, the fixing block 513 is attached to the clamping plate 511 to clamp and fix the fabric.

[0036] (3) By manually pushing the push rod 48, the turntable 41 is rotated, which in turn drives the winding roller 45 and the take-up groove 46 to rotate, thereby realizing the retraction of the wire rope 47, so that the clamping device 5 can slide in the slide groove 44 through the slider 43, thereby moving the clamping device 5 to the corresponding position of the sewing equipment in the mounting frame 1, thus facilitating the processing of the fabric.

[0037] (4) After the fabric is processed, the clamping device 5 is reset by sliding the slider 43 in the groove 44 under the action of the first spring.

[0038] In this embodiment, by setting a moving device and a first elastic element inside the mounting frame, and connecting the mounting frame to the clamping device through the first elastic element, the moving device is connected to the clamping device through a sliding connection, allowing the moving device to drive the clamping device to move inside the mounting frame. After moving, the clamping device can be reset by a first spring, facilitating the processing of the clamped fabric and thus improving production efficiency. By connecting the front end of the mounting frame to the extension table, it is convenient to place the fabric on the extension table, which is convenient for sewing. Since a slide, clamping plate, and lifting drive are provided, it is convenient to clamp the fabric.
