[0051] 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.

[0052] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] This invention discloses a garment sewing lining laying device, including a fixing base 2, a clamping assembly 3, and a lifting and pressing assembly 4. The fixing base 2 is fixed to the machine head 1, as shown in the attached figure. Figure 1 As shown, the fixing base 2 provides support. (See attached diagram) Figures 2 to 4 As shown, the clamping assembly 3 is used to clamp the garment sewing interlining 5, which can be a horsehair interlining, etc. (See attached image.) Figure 10 As shown, the garment sewing interlining 5 involves continuously spreading radially brush-like material into the seam. Two to three brush-like materials are wrapped between each adjacent stitch, providing sufficient thread allowance to reduce shrinkage. The garment sewing interlining 5 is preferably horsehair interlining. Materials used to manufacture this horsehair interlining mainly include chemical fibers (polyester fibers, etc.), synthetic fibers, cellulose functional materials, polyester, resin interlining, PBT plastic, linen interlining, and nylon, possessing advantages such as good flexibility, tear resistance, adhesion, and abrasion resistance. PBT stands for polybutylene terephthalate.

[0054] The clamping assembly 3 is rotatably mounted on the fixed base 2, causing the clamping assembly 3 to drive the garment sewing lining 5 to rotate relative to the fixed base 2. The lifting and pressing assembly 4 is fixed to the fixed base 2 and rotatably connected to the clamping assembly 3. It can both allow the clamping assembly 3 to rotate relative to the lifting and pressing assembly 4 and allow the lifting and pressing assembly 4 to lift or lower the clamping assembly 3, adjusting the relative position between the garment sewing lining 5 and the seam thread.

[0055] When in lining sewing mode, the lifting and pressing component 4 presses down the clamping component 3, meaning the clamping component 3 moves downward relative to the fixed base 2. The clamping component 3 pulls the garment lining 5 closer to the seam. Simultaneously, the clamping component 3 continuously rotates relative to the fixed base 2, causing the clamped garment lining 5 to rotate synchronously, achieving continuous laying of the garment lining 5 along the seam without manual laying, saving time and effort. The lining sewing mode mentioned in this text refers to the sewing machine being in the garment lining sewing mode.

[0056] When in normal sewing mode, the lifting and pressing component 4 raises the clamping component 3, meaning the clamping component 3 moves upward relative to the fixed base 2. The clamping component 3 pulls the held garment interlining 5 away from the seam and stops rotating, thus stopping the laying of the garment interlining 5. The normal sewing mode mentioned in this text refers to the sewing machine being in the normal fabric sewing mode.

[0057] This invention designs a garment sewing interlining laying device that can continuously lay garment sewing interlining 5 in interlining sewing mode and raise garment sewing interlining 5 in normal sewing mode. That is, it can automatically and continuously lay garment sewing interlining without affecting normal sewing. It has a high degree of automation, eliminates the need for manual laying of garment sewing interlining, saves time and labor in the production process, greatly reduces ineffective working time, and has high production efficiency.

[0058] As attached Figure 2 As shown, the clamping assembly 3 includes a rotating sleeve 31 and a clamping head 32. The rotating sleeve 31 is a hollow structure and is rotatably mounted to drive the clamping head 32 and the garment lining it holds to rotate synchronously. The clamping head 32 is slidably mounted at the end of the rotating sleeve 31, specifically at the end of the rotating sleeve 31 away from the drive cylinder. It is used to clamp the garment sewing lining 5 and drive the garment sewing lining 5 to slide relative to the rotating sleeve 31, thereby achieving floating lifting and pressing of the garment sewing lining 5 and ensuring the controllability of sewing mode switching.

[0059] As attached Figure 2 As shown, the free end of the rotating sleeve 31 has an oblong hole 311 extending along its axial direction, which serves as a guide. The free end in this text refers to the end of the rotating sleeve 31 furthest from the drive cylinder. (See attached image.) Figure 4 As shown, the clamping head 32 includes an upper clamping sleeve 321 and a lower clamping sleeve 322 that are coaxially nested and detachably connected, facilitating adjustment of the axial distance between the upper clamping sleeve 321 and the lower clamping sleeve 322. This allows for the clamping of garment sewing interlinings 5 ​​of different thicknesses between the upper clamping sleeve 321 and the lower clamping sleeve 322, providing good adaptability. (See attached...) Figure 3 As shown, the upper sleeve 321 is stepped, with its small-diameter end fitted onto the rotating sleeve 31, and its large-diameter end nested with the lower sleeve 322. The end of the lower sleeve 322 exposed outside the upper sleeve 322 is integrally provided with a clamping flange, and an annular clamping groove is formed between the end faces of the clamping flange and the upper sleeve 321 for clamping the garment sewing lining 5.

[0060] The upper sleeve 321 is fixed with a guide pin 33 extending radially therefrom, the guide pin 33 passing through the oblong hole 311, so that the guide pin 33 guides the upper sleeve 321 to slide relative to the rotating sleeve 31. Of course, the floating connection between the rotating sleeve 31 and the clamping head 32 is not limited to this.

[0061] As attached Figures 2 to 4 As shown, the clamping assembly 3 includes an inner sliding sleeve 34, which is slidably disposed on the rotating sleeve 31. The central hole of the rotating sleeve 31 guides the inner sliding sleeve 34 to slide relative to the rotating sleeve 31 along the axial direction of the rotating sleeve 31. A guide pin 33 passes through the inner sliding sleeve 34, and the inner sliding sleeve 34 and the upper clamping sleeve 321 slide synchronously relative to the rotating sleeve 31 under the joint guidance of the guide pin 33 and the waist-shaped hole 311.

[0062] As attached Figure 3 and 4 As shown, the lifting and pressing assembly 4 includes a connecting shaft 41, which is a hollow structure and coaxially disposed within the rotating sleeve 31. The connecting shaft 41 and the inner sliding sleeve 34 are coaxially nested and rotate relative to each other, thereby causing the clamping assembly 3 to rotate relative to the lifting and pressing assembly 4. Of course, the rotational connection between the clamping assembly 3 and the lifting and pressing assembly 4 is not limited to this.

[0063] As attached Figure 4 and 7 As shown, an inner bearing 6 is provided between the connecting shaft 41 and the inner sleeve 34 to support the rotation of the inner sleeve 34 relative to the connecting shaft 41. The inner bearing 6 is located on the rotating sleeve 31. A shaft screw 42 is fixed to the end of the connecting shaft 41. The clamping assembly 3 also includes a bearing block 35 coaxially located inside the inner sleeve 34 and transversely located through the guide pin 33. The bearing block 35, the inner sleeve 34, the rotating sleeve 31, and the upper clamping sleeve 321 are arranged sequentially from the inside to the outside, and are connected by the radially passing guide pin 33. The bearing block 35 and the shaft screw 42 respectively abut against the outer ring and inner ring of the first end of the inner bearing 6. That is, the end face of the bearing block 35 abuts against the outer ring of the first end of the inner bearing 6 under the support of the guide pin 33, and the head of the shaft screw 42 abuts against the inner ring of the first end of the inner bearing 6, thereby achieving axial positioning of the first end of the inner bearing 6. A stop ring 341 is formed inside the inner sleeve 34, as shown in the attached figure. Figure 2 and 9 As shown, the end faces of the stop ring 341 and the connecting shaft 41 respectively abut against the outer ring and inner ring of the second end of the inner bearing 6. That is, the end face of the stop ring 341 abuts against the outer ring of the second end of the inner bearing 6, and the end face of the connecting shaft 41 abuts against the inner ring of the second end of the inner bearing 6, thereby achieving axial positioning of the second end of the inner bearing 6. Of course, the positioning method of the inner bearing 6 is not limited to this.

[0064] As attached Figure 4 and 5 As shown, the lifting assembly 4 also includes a fixedly mounted lifting cylinder 43. The piston rod 431 of the lifting cylinder 43 is inserted into the rotating sleeve 31. The piston rod 431 and the connecting shaft 41 are elastically connected by an elastic element 44, as shown in the attached figure. Figure 4 and 6As shown. In the lining sewing mode, the piston rod 431 of the lifting cylinder 43 extends outward, the elastic element 44 is stretched, and the piston rod 431 pushes the clamping head 32 downward relative to the rotating sleeve 31 through the connecting shaft 41, pressing down the garment sewing lining 5. In the normal sewing mode, the piston rod 431 of the lifting cylinder 43 retracts, the elastic element 44 recovers its elastic deformation, and the elastic element 44 drives the piston rod 431 to quickly move upward and reset by elastic force. The connecting shaft 41 drives the clamping head 32 to move upward relative to the rotating sleeve 31, lifting the garment sewing lining 5. The elastic element 44 is designed to assist the piston rod 431 in quickly resetting. The elastic element 44 can be a cylindrical spring, but is not limited to this. The cylinder of the lifting cylinder 43 is connected to an air pipe connector 432, which is connected to an external air supply pipe to supply air to the lifting cylinder 43.

[0065] As attached Figure 6 and 8 The connecting shaft 41 has an elongated hole 411 on its side wall, which extends axially along the connecting shaft 41. The elastic element 44 is equipped with a hook for moving away from the piston rod 431, and the hook is engaged within the elongated hole 411. The elongated hole 411 reduces the assembly difficulty between the connecting shaft 41 and the elastic element 44. To prevent the elastic element 44 from detaching from the connecting shaft 41, an annular groove 412 is provided on the outer surface of the connecting shaft 41. An elastic retaining ring 45 is fixed within the annular groove 412, abutting against the hook and pressing it to ensure a reliable connection between the elastic element 44 and the connecting shaft 41.

[0066] As attached Figure 2 As shown, the above-mentioned garment sewing lining laying device also includes a drive motor 7 and a transmission mechanism 8 connected to the drive motor 7. The transmission mechanism 8 includes a driving pulley 81, a driven pulley 82, and a synchronous belt 83. The drive motor 7 is fixedly connected to the driving pulley 81, the driven pulley 82 is fixedly sleeved on the outside of the rotating sleeve 31, and the synchronous belt 83 is wound between the driving pulley 81 and the driven pulley 82. The torque of the drive motor 7 is transmitted from the driving pulley 81 to the driven pulley 82 through the synchronous belt 83, causing the driving pulley 81 to drive the driven pulley 82 to rotate, which in turn causes the driven pulley 82 to drive the rotating sleeve 31 to rotate, thus causing the clamping assembly 3 to rotate. The transmission mechanism 8 serves to reduce speed and can be replaced by a gear transmission mechanism or a sprocket transmission mechanism, etc., without specific limitation here. The driven pulley 82 and the rotating sleeve 31 are preferably connected by an interference fit to keep them rotating synchronously.

[0067] As attached Figure 1 and 2As shown, the above-mentioned garment sewing lining laying device also includes a motor base 9 and a cylinder base 10. The motor base 9 is fixedly connected to the fixed base 2 and is used to support the drive motor 7. The cylinder base 10 is fixed to the motor base 9 and is used to support the lifting cylinder 43, ensuring that the lifting cylinder 43 is reliably fixed. At least one spring pin 13 is inserted between the fixed base 2 and the motor base 9 to fix the fixed base 2 to the motor base 9. The motor base 9 is fixed to the machine head 1 by fastening screws.

[0068] As attached Figure 4 As shown, an outer bearing 11 is provided between the fixed base 2 and the rotating sleeve 31 to support the rotation of the rotating sleeve 31 relative to the fixed base 2. Considering the weight of the clamping assembly 3 and the weight of the garment sewing lining 5, two outer bearings 11 are preferably provided between the fixed base 2 and the rotating sleeve 31. Of course, the number of outer bearings 11 is not limited to this. A limiting screw 12 is fixedly provided at the bottom of the fixed base 2. The limiting step 312 and the limiting screw 12 abut against the inner and outer rings at the bottom of the outer bearing 11, respectively. That is, the end face of the limiting step 312 abuts against the inner ring at the bottom of the outer bearing 11, and the head of the limiting screw 12 abuts against the outer ring at the bottom of the outer bearing 11, realizing the axial movement of the outer bearing 11. A limiting sleeve is fixedly fitted on the outer side wall of the rotating sleeve 31. The limiting sleeve abuts against the inner and outer rings at the top of the outer bearing 11, so that the limiting sleeve and the limiting screw 12 together limit the movement of the outer bearing 11 along its own axial direction. Of course, the limiting method of the outer bearing 11 is not limited to this.

[0069] This invention discloses a sewing machine, including a machine head 1 and the aforementioned garment sewing lining laying device. The garment sewing lining laying device is fixed to the machine head 1 and has the same beneficial effects.
