Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a first dart presser foot drive structure for fabric double dart gathering. Background Technology

[0002] The core problem with current automated dart gathering devices on the market is that they can generally only complete a single dart gathering process, meaning they cannot achieve continuous automated sewing of multiple darts. Furthermore, the key components of these automated dart gathering devices (such as presser feet and their drive structures) are designed for a single sewing process, resulting in a lack of adaptability and flexibility in their structure for continuous sewing.

[0003] This inherent design limitation forces companies to revert to an inefficient, step-by-step manual operation mode when handling multi-dart sewing tasks, heavily relying on skilled workers and severely restricting production efficiency and product quality consistency. Therefore, developing a presser foot and its drive structure suitable for continuous, efficient dart sewing has become an urgent need for the industry. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a first-line presser foot drive structure for fabric double-line gathering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A first dart presser foot drive structure for fabric gathering double darts includes: a drive member disposed on a mounting plate, wherein a presser foot assembly is connected to the drive end of the drive member and is capable of driving the presser foot assembly to move up and down; the presser foot assembly includes a pressure frame and a presser foot plate disposed on the pressure frame, wherein the presser foot plate is provided with a pressing part for pressing down on the first gathering dart edge of the fabric, and the pressure frame is provided with a side pressure plate for pressing down on the second gathering dart edge of the fabric.

[0007] Preferably, the driving component includes a presser foot cylinder, the driving end of which is connected to the presser frame.

[0008] Preferably, the presser foot plate is oscillatingly connected to the pressure frame via the rotating rod of the pressure frame, and the presser foot plate is provided with presser foot abutment strips on both sides of the rotating rod with opposite abutment portions below the presser foot plate. The presser foot abutment strips can abut against the presser foot plate upward and drive it to oscillate.

[0009] Preferably, the presser foot plate is provided with a screw that can abut against the presser foot abutment bar downwards.

[0010] Preferably, the screw is threaded onto the pressure foot plate.

[0011] Preferably, the pressure frame is provided with a limiting strip located between the side pressure plate and the rotating rod, which can abut against the pressure foot plate and swing upward.

[0012] The beneficial effects of this utility model are:

[0013] 1. Connect the presser foot plate to the presser frame of the presser foot assembly. Drive the presser foot assembly to rise and fall so that the presser frame and the presser foot plate respectively press against the first and second dart edges of the fabric. This achieves continuous and stable pressing and positioning of the fabric at the first and second dart edges when sewing two darts, ensuring that two darts can be sewn continuously and effectively improving the processing efficiency and quality when sewing double darts.

[0014] 2. The presser foot is oscillating on the presser frame. When the presser frame and the presser foot are displaced downwards, the presser foot comes into contact with the presser foot abutment strip and drives the presser foot to oscillate along the rotating rod, so that the pressing part can press the fabric more stably and reliably, thereby ensuring the processing quality of the fabric during the first dart sewing.

[0015] 3. The screw is threaded onto the presser foot plate, and the length of the screw extending downwards through the presser foot plate is adjusted by the thread to adapt to the swing angle of the presser foot plate. When the fabric being sewn is thicker, the screw can be turned upwards appropriately so that the screw can make contact with the presser foot abutment later, thereby providing a larger swing angle for the presser foot plate. This allows for adjustment to suit the processing of fabrics of different thicknesses. Furthermore, adjusting the swing angle of the presser foot plate by rotating the screw makes the operation and debugging of the equipment more convenient. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Example 1:

[0037] like Figures 1-4 As shown, this embodiment discloses a first dart presser foot drive structure for fabric double dart taking, including: a drive member, which is disposed on a mounting plate 3, the drive end of the drive member is connected to the presser foot assembly and can drive the presser foot assembly to move up and down; the presser foot assembly includes a presser frame 5 and a presser foot plate 4 disposed on the presser frame 5.

[0038] Specifically, the driving component on the mounting plate 3 includes a foot presser cylinder 33. The driving end of the foot presser cylinder 33 is connected to the pressure frame 5, thereby driving the pressure frame 5 and the foot presser plate 4 to move up and down through the foot presser cylinder 33.

[0039] The presser foot 4 is oscillatingly mounted on the presser frame 5. The presser foot 4 is provided with a pressing part 42 for pressing down on the first dart edge of the fabric 6. The presser frame 5 is provided with a side pressing plate 53 for pressing down on the second dart edge of the fabric 6. The pressing part 42 of the presser foot 4 oscillates and presses against the folded edge 211, that is, the pressing part 42 is used to press down on the first dart edge at the folded edge 211.

[0040] The presser foot assembly is raised and lowered by the drive component to move the presser frame 5 and the presser foot plate 4 to press the first and second dart edges of the fabric respectively. This achieves continuous and stable pressing and positioning of the fabric 6 at the first and second dart edges when sewing two darts, ensuring that two darts can be sewn continuously and effectively improving the processing efficiency and quality when sewing double darts.

[0041] The presser foot plate 4 is swayed and connected to the pressure frame 5 via the rotating rod 51 of the pressure frame 5. The presser foot plate 4 is provided with presser foot abutment strips 23 on both sides of the rotating rod 51 with opposing abutment parts 42. The presser foot abutment strips 23 can abut against the presser foot plate 4 upward and drive it to swing.

[0042] By swinging the presser foot 4 onto the presser frame 5, when the presser frame 5 and the presser foot 4 move downward, the presser foot 4 comes into contact with the presser foot abutment 23 and drives the presser foot 4 to swing along the rotating rod 51, so that the pressing part 42 can press the fabric 6 more stably and reliably, thereby ensuring the processing quality of the fabric 6 during the first dart sewing.

[0043] Furthermore, the presser foot plate 4 is provided with a screw 41 that can abut downward against the presser foot abutment strip 23. The screw 41 is threaded onto the presser foot plate 4. By adjusting the length of the screw 41 extending downward through the presser foot plate 4, the swing angle of the presser foot plate 4 can be adaptively adjusted. When the fabric 6 being sewn is thicker, the screw 41 can be turned upward appropriately so that the screw 41 can abut against the presser foot abutment strip 23 later, thereby providing a larger swing angle for the presser foot plate 4. This allows it to be adjusted for processing fabrics 6 of different thicknesses. Moreover, by rotating the screw 41, the swing angle of the presser foot plate 4 can be adjusted, making the use and debugging operation of this embodiment more convenient.

[0044] The pressure frame 5 is provided with a limiting strip 52 located between the side pressure plate 53 and the rotating rod 51, which can abut against the pressure foot plate 4 and swing upward. The limiting strip 52 is used to abut against the pressure foot plate 4 and limit its upward swing limit position.

[0045] like Figures 1 to 16 As shown, this embodiment also discloses a fabric double-dart processing device, including the first dart presser foot drive structure mentioned above and a template that is lifted and set on the base plate 1. The template includes a forming piece 32, a retracting piece 21 and a prying piece 22 arranged in a vertically distributed manner. It can also be understood that the template includes a forming piece 32, a prying piece 22 and a retracting piece 21 arranged in a vertically distributed manner.

[0046] A lifting cylinder 12 is installed on the base plate 1. The paddle 22 and the retractor 21 are laterally disposed on the lifting plate 2, which is capable of vertical displacement. The lifting plate 2 is connected to the drive end of the lifting cylinder 12. The lifting plate 2 is slidably disposed with a mounting plate 3 for mounting the forming piece 32, so that the lifting plate 2 and the mounting plate 3 are driven to move vertically by the lifting cylinder 12, thereby driving the forming piece 32, the paddle 22, and the retractor 21 to move vertically.

[0047] The paddle 22 and the retractor 21 can be laterally moved relative to the forming piece 32. The lifting plate 2 is provided with driving components connected to the paddle 22 and the retractor 21 respectively. The driving components can be cylinders. Specifically, the two driving components include a first driving cylinder 213 and a second driving cylinder 221 respectively provided on the lifting plate 2. The lifting plate 2 is provided with a first sliding bar 215 and a second sliding bar 223 arranged horizontally. The piston rod of the first driving cylinder 213 is connected to the first slider 214 and drives the first slider 214 to slide laterally along the first sliding bar 215. The retractor 21 is fixed on the first slider 214, and then the retractor 21 is driven to move laterally synchronously through the first slider 214.

[0048] The second slider 222 is connected to the driving end of the driving component and is slidably disposed on the second slider 223. That is, the piston rod of the second driving cylinder 221 is connected to the second slider 222 and drives the second slider 222 to slide laterally along the second slider 223. The paddle 22 is fixedly disposed on the second slider 222, and then the second slider 222 drives the paddle 22 to move laterally synchronously.

[0049] The molding sheet 32 ​​and the unmolded sheet 21 have inclined folded edge portion 221 and folded edge portion 211 respectively on the same side. One end of the molding sheet 32 ​​is disposed on the mounting plate 3, and the other end of the molding sheet 32 ​​extends outward and is suspended. As the molding sheet 32 ​​extends towards its suspended end, the width of folded edge portion 221 gradually decreases.

[0050] One end of the paddle 22 and the retractor 21 is disposed on the lifting plate 2, and the other end of the paddle 22 and the retractor 21 extends outward and is suspended. As the retractor 21 extends towards its suspended end, the width of the folded edge 211 gradually decreases.

[0051] The first folded edge 211 and the second folded edge 321 are staggered, and the first folded edge 211 extends to the outside of the paddle 22 and the second folded edge 321. Fabric 6 is wrapped around the forming piece 32, the paddle 22, and the shear piece 21. The fabric 6 is close to the first folded edge 211 and the second folded edge 321. The fabric 6 is folded at the first folded edge 211 and the second folded edge 321, and correspondingly forms an inclined first dart edge and a second dart edge.

[0052] The molding sheet 32 ​​has a seam opening 322 for sewing darts at the second dart edge. The second folded edge portion 321 is elongated. The seam opening 322 is located on one side of the folded edge portion 321. The molding sheet 32 ​​is provided with a pressure plate 323 that can press down on the fabric 6. A reinforcing plate 325 is fixed to the upper end of the pressure plate 323. The seam opening 322 is strip-shaped and located between the pressure plate 323 and the second folded edge portion 321. One end of the seam opening 322 intersects with the inclined edge of the second folded edge portion 321 to form an opening 324.

[0053] By setting the seam opening 322, the second dart can be sewn without removing the forming piece 32 when sewing the second dart. This not only simplifies the sewing process and improves processing efficiency, but also ensures the flatness of the fabric when sewing the second dart continuously, making the automated continuous sewing of the second dart more reliable.

[0054] Furthermore, by setting a pressure plate 323 on the forming piece 32, the pressure plate 323 can flatly press down the fabric 6 wrapped under the forming piece 32 when sewing the second dart, and by opening a seam opening 322 to provide a clearance for sewing the second dart line, the stability and quality of sewing the fabric 6 when sewing the second dart are further ensured by using the cooperation between the pressure plate 323 and the seam opening 322.

[0055] Meanwhile, by opening an opening 324 at one end of the seam opening 322, the fabric 6 can be pulled out from the opening 324 after the second dart is sewn, making the fabric 6 easier to collect and thus improving the overall efficiency of the double dart sewing process.

[0056] The base plate 1 is provided with a needle groove 11, which corresponds to the position of the folded edge 211 and the seam opening 322. That is, the needle groove 11 and the needle groove 11 and the seam opening 322 are used to sew the first dart edge and the second dart edge.

[0057] Furthermore, a presser foot assembly is provided above the template for lifting and lowering. The presser foot assembly has a presser foot plate 4 corresponding to the folded edge 211, which can press down on the first gathered edge through the presser foot plate 4. The presser foot assembly also has a pressure frame 5, on which the presser foot plate 4 is disposed. The pressure frame 5 is provided with a side pressure plate 53 corresponding to the forming piece 32 and capable of pressing down on the second gathered edge.

[0058] The presser foot plate 4 has a sewing opening 43 corresponding to the folded edge 211. The sewing opening 43 is located on one side of the pressing part 42. That is, the sewing opening 43 cooperates with the needle groove 11 to sew the first dart at the first dart edge.

[0059] Furthermore, the presser foot plate 4 is provided with pressing strips 44 distributed on both sides of the sewing opening 43, with the pressing part 42 opposite to the pressing part 42. The sewing opening 43 is located between the pressing part 42 and the pressing strip 44. The pressing part 42 and the pressing strip 44 can press down on the folded edge 211, that is, the pressing part 42 and the pressing strip 44 cooperate to press down on the first dart edge, so as to improve the stability and quality of the first dart sewing.

[0060] By setting a forming piece 32 below the side pressure plate 53, the side pressure plate 53 presses down on the forming piece 32 to press against the second dart edge on the upper surface of the forming piece 32, and the forming piece 32 moves downward to press against the second dart edge on its lower surface. This, in turn, presses against the second dart edge of the shaping fabric 6 from both above and below, so that the second dart edge can be in a stable pressing and shaping state. This improves the quality of sewing the second dart line on the fabric 6 at the second dart edge, allowing the fabric 6 to sew two dart lines more efficiently and stably.

[0061] The side pressure plate 53 has a sewing notch 54 on one side that corresponds to the seam opening 322. The sewing notch 54 is located between the side pressure plate 53 and the pressing part 42 and corresponds to the second dart edge. The sewing notch 54 provides a clearance for sewing the second dart, that is, the second dart can be sewn by cooperating with the needle groove 11 through the seam opening 322.

[0062] Furthermore, by driving the presser foot assembly to rise and fall, the presser frame 5 and the presser foot plate 4 respectively press against the first and second dart edges of the fabric 6. A sewing opening 43 for sewing the first dart and a sewing notch 54 for sewing the second dart are respectively opened on the presser foot plate 4 and the presser frame 5. This achieves continuous and stable pressing and positioning of the fabric 6 at the first and second dart edges when sewing two darts, ensuring that two darts can be sewn continuously and effectively improving the efficiency and quality of double dart sewing.

[0063] Furthermore, by wrapping the fabric 6 between the forming piece 32, the prying piece 22, and the retracting piece 21, and by closely adhering to the first folding edge 211 and the second folding edge 321 to form an inclined first dart edge and a second dart edge, and then pressing the fabric 6 down through the forming piece 32, the prying piece 22, the retracting piece 21 and the presser foot assembly, the fabric 6 is placed and shaped in one step, thereby reducing the difficulty of dart sewing and ensuring the quality of subsequent dart sewing of the fabric 6.

[0064] Furthermore, the ejector piece 21 is provided with a pressing part 212 for pressing the fabric 6. The pressing part 212 and the folding part 211 together form the ejector piece 21. The pressing part 212 and the folding part 211 can be an integral structure or a separate structure. The pressing part 212 is located below the forming piece 32. That is, the pressing part 212 is provided on the ejector piece 21 to flatten and press against the fabric 6. When the ejector piece 21 is moved away, the pressing part 212 can effectively ensure the flatness of the fabric 6 and prevent the fabric 6 from wrinkling due to the removal of the ejector piece 21. This ensures the quality of the fabric 6 when sewing the first dart gather, thereby improving the stability of the automated dart gather sewing of the fabric 6.

[0065] To further ensure the quality of the second dart sewing in this embodiment, the forming piece 32 is disposed on one side of the mounting plate 3, and the forming piece 32 can press down against the paddle 22 located below it. Fabric 6 is wrapped between the forming piece 32 and the paddle 22. The mounting plate 3 is slidably disposed on the lifting plate 2. The lifting plate 2 is provided with vertically distributed slide bars 25, and the mounting plate 3 is provided with a slider 31 slidably connected to the slide bars 25.

[0066] The paddle 22 is horizontally mounted on the lifting plate 2 and connected to the roller 233. The roller 233 is horizontally mounted and can tilt down and press down on the mounting plate 3 on one side of the forming piece 32, so as to drive the forming piece 32 to move downward a certain distance.

[0067] Specifically, the lifting plate 2 is provided with a smooth groove 24 and a roller 233 that is slidably inserted into the smooth groove 24. The mounting plate 3 is provided with an inclined sliding groove 34 for the roller 233 to slide into. The inclined sliding groove 34 is located at one end of the forming piece 32 and is inclined upward.

[0068] Furthermore, when the lever 22 moves laterally to prepare for sewing the second dart, the roller 233 slides laterally synchronously with the lever 22 within the smooth groove 24 and the oblique groove 34. During the sliding process, the roller 22 can slide to the upward-sloping end of the oblique groove 34. Consequently, the roller 233 will press down on one side of the mounting plate 3 and drive the forming piece 32 to press down on the fabric 6. That is, the downward displacement of the forming piece 32 compensates for the space after the lever 22 and the withdrawing piece 21 are removed, so as to avoid the forming piece 32 being in a suspended state. Furthermore, by the downward displacement of the forming piece 32 and pressing down on the fabric 6, the forming piece 32 can more effectively press down and shape the fabric 6 to be sewn for the second dart, thereby improving the quality of sewing the second dart and ensuring that the second dart can be sewn continuously and reliably.

[0069] The lever 22 is connected to a connecting plate 231. The connecting plate 231 is provided with a fixing block 232 for mounting the roller 233 and a pressure foot abutment strip 23 for abutting the pressure foot plate 4 and driving the pressure foot plate 4 to swing and press against the folded edge part 211. The slider 222 is fixed to the connecting plate 231, so that the roller 233 and the pressure foot abutment strip 23 can maintain synchronous lateral displacement with the lever 22 through the connecting plate 231.

[0070] That is, by linking the paddle 22 with the roller 233, a single driving component can drive the paddle 22 and the roller 233 to move synchronously, thereby simplifying the driving structure, improving processing efficiency, and reducing the drive failure rate.

[0071] Furthermore, when the roller 233 presses down on one side of the mounting plate 3, the pressing part 42 of the pressure foot plate 4 on the mounting plate 3 will exceed the originally designed pressing stroke, which may lead to excessive pressing and structural deformation. At the same time, it will also affect the accuracy and quality of the machining. Therefore, in this embodiment, the pressure foot abutment 23 is connected to the lever 22. When the lever 22 is moved laterally and pulled away, the pressure foot abutment 23 can move laterally synchronously with the lever 22 and intersect with the screw 41 to provide additional upward swing space for the pressure foot plate 4, thereby effectively avoiding quality problems caused by the over-travel of the pressing part 42.

[0072] This embodiment is equipped with an airlock mechanism, which allows the entire embodiment to be connected to an existing template machine, thus adapting the embodiment to the template machine and further improving the automation level of the fabric gathering and double-dish processing. The airlock mechanism can be a cylinder and pin structure, where the cylinder drives the pin to move and insert it to fix it on the template machine, thereby achieving a fixed adaptation between the embodiment and the template machine.

[0073] This embodiment also discloses a processing method for fabric gathering double darts, including:

[0074] S1. The fabric 6 is wrapped around the forming piece 32, the pry piece 22, and the shear piece 21 and is tightly attached to the first folded edge 211 and the second folded edge 321. The fabric 6 is folded at the first folded edge 211 and the second folded edge 321, and correspondingly forms the first dart edge and the second dart edge, so as to realize the placement and shaping of the fabric 6 in one step, thereby reducing the difficulty of dart sewing and ensuring the quality of subsequent dart sewing of the fabric 6.

[0075] S2, forming piece 32, prying piece 22, and withdrawing piece 21 drive the fabric 6 to press down and press down the first gathering edge on the withdrawing piece 21 and the second gathering edge on the forming piece 32 through the presser foot assembly;

[0076] S3. Laterally move the withdrawing piece 21 and move the template to the sewing area to sew the first dart at the first dart edge;

[0077] S4. Laterally move the puller 22 away to move the fabric wrapped around it away from the second dart along with the first dart edge.

[0078] S5. Sew the second dart along the seam opening 322 of the formed piece 32 to complete the fabric double dart gathering.

[0079] By pressing the first and second dart edges with the presser foot assembly, and successively pulling away the withdrawing piece 21 and the pulling piece 22, the first and second darts of the fabric can be darted respectively. That is, through the cooperation of the forming piece 32, the pulling piece 22, and the withdrawing piece 21 of the template, the two darts are automatically sewn, thereby simplifying the two dart processing steps and improving the efficiency and quality of sewing six darts of the fabric.

[0080] Furthermore, the presser foot assembly presses downward against the second dart edge on the upper surface of the forming sheet 32, and the forming sheet 32 ​​presses downward against the lever 22 and cooperates with the lever 22 to press against the second dart edge on the lower surface of the forming sheet 32, so as to press against the second dart edge of the shaping fabric.

[0081] When the lever 22 is moved laterally and pulled away, the forming piece 32 presses down on the fabric to press the second dart edge against the base plate 1, so as to ensure that the fabric at the second dart edge can be in a relatively stable pressing state for dart sewing.

[0082] Example 2:

[0083] like Figure 17 As shown, this embodiment also discloses a processing method for fabric double darts. The difference between this embodiment and embodiment 1 is that this embodiment includes a strip 21, a pusher 22 and a forming piece 32 distributed from top to bottom. By placing the forming piece 32 at the bottom layer of the template, the forming piece 32 can more stably press against the fabric 6 on the base plate 1, thereby effectively improving the quality when sewing the second dart.

[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
