Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-8 As shown, an automatic feeding sewing machine is provided, including a controller 1, a feeding mechanism 2, a transfer mechanism 3, and a sewing mechanism 4. The controller 1 is located on the feeding mechanism 2, which is located on one side of the sewing mechanism 4 and is used to transport materials to the sewing mechanism 4. The feeding mechanism 2, the transfer mechanism 3, and the sewing mechanism 4 are all electrically connected to the controller 1.

[0030] The feeding mechanism 2 includes a feeding frame 21, a feeding adjustment component 22, a lifting feeding component 23, and a detection feeding component 24. The feeding adjustment component 22, the lifting feeding component 23, and the detection feeding component 24 are sequentially arranged on the feeding frame 21.

[0031] The detection and feeding assembly 24 includes a detection base 241, a detection rod 242, a proximity sensor 243, and an alarm 244. The detection base 241 is fixedly connected to the lifting slide plate 231 and slidably connected to the feeding frame 21. The detection rod 242 is fixedly connected to the detection base 241. The proximity sensor 243 is fixedly connected to the detection rod 242 and electrically connected to the lifting and feeding assembly 23 and the controller 1, respectively. The alarm 244 is fixedly connected to the detection rod 242 and is located on one side of the proximity sensor 243. The alarm 244 is electrically connected to the proximity sensor 243 and the controller 1, respectively. The proximity sensor 243 can be a reflector-type infrared sensor, specifically the OMRON E3Z-R61. The detection distance can be adjusted between 1-30cm, and the sensing distance can be stably set to 20cm. It combines the advantages of diffuse reflection and through-beam types, has high detection accuracy, and is suitable for detection scenarios requiring precise material positioning. It can be used in the feeding mechanism 2 to determine whether the material has been conveyed to the designated position. The proximity sensor 243 has a preset sensing distance of 20cm and monitors the material on the feeding plate 235 in real time. When the material enters the 20cm sensing range, the proximity sensor 243 sends a signal to the controller 1 and the lifting feeding assembly 23. The controller 1 instructs the feeding motor 232 to stop running, and the feeding plate 235 stops lifting. If the material is below the sensing range (about to run out of material), the proximity sensor 243 triggers a signal to the controller 1 and the alarm 244. The controller 1 starts the lifting feeding assembly 23 to replenish the material, and at the same time, the alarm 244 sounds an alarm to remind the operator, realizing the coordinated operation of material detection, automatic replenishment, and material shortage warning.

[0032] The transfer mechanism 3 includes a transfer pushing component 31, a transfer lifting component 32, and a transfer component 33. The transfer pushing component 31 is respectively installed on the sewing mechanism 4 and the transfer lifting component 32. The transfer component 33 is installed on the transfer lifting component 32 and is electrically connected to the controller 1.

[0033] The sewing mechanism 4 includes a sewing machine frame 41, a sewing assembly 42, a fixture assembly 43, and a displacement assembly 44. The sewing assembly 42 is disposed on the sewing machine frame 41, the fixture assembly 43 is disposed on the sewing assembly 42, and the displacement assembly 44 is disposed on the sewing machine frame 41 and the fixture assembly 43, respectively.

[0034] The automatic feeding sewing machine provided in this application can detect the presence of materials in real time by detecting the proximity sensor 243 in the feeding component 24, and promptly feed back the detection signal to the controller 1 and the lifting feeding component 23. When it is detected that the material is about to be short, the controller 1 can promptly control the lifting feeding component 23 to perform a material replenishment operation, which effectively avoids machine stagnation caused by material shortage, ensures the continuity of production, and improves production efficiency.

[0035] In another embodiment of this utility model, the feeding adjustment component 22 includes a feeding slide rail 221, a feeding slider 222, and a feeding slide plate 223. The feeding slide rail 221 is fixedly connected to the feeding frame 21, the feeding slider 222 is slidably connected to the feeding slide rail 221, and the feeding slide plate 223 is fixedly connected to the feeding slider 222. The lifting feeding component 23 is fixedly connected to the feeding slider 222. The feeding adjustment component 22 is used in the feeding mechanism 2 to flexibly adjust the material conveying position. The feeding slide rail 221 is fixed to the feeding frame 21, providing a stable guiding foundation for the entire adjustment process. The feeding slider 222 is slidably connected to the feeding slide rail 221 and can move freely along the length of the slide rail, driving the feeding slide plate 223 fixed thereto to move synchronously. By sliding the feeding slider 222 on the slide rail, the horizontal position of the feeding slide plate 223 can be easily adjusted, thereby adapting to the feeding requirements of materials of different sizes and specifications. Meanwhile, since the lifting and feeding component 23 is fixedly connected to the feeding slider 222, the position adjustment of the feeding adjustment component 22 will synchronously drive the lifting and feeding component 23 to move, ensuring that the lifting and feeding component 23 is precisely coordinated with the subsequent detection and feeding component 24 and the transfer mechanism 3.

[0036] In another embodiment of this utility model, the lifting and feeding assembly 23 includes a lifting slide plate 231, a feeding motor 232, a feeding screw 233, a feeding nut 234, a feeding plate 235, and a motor plate 236. The lifting slide plate 231 is fixedly connected to the feeding slider 222 and slidably connected to the feeding frame 21. The feeding motor 232 is fixedly connected to the motor plate 236 and electrically connected to the controller 1 and the proximity sensor 243, respectively. The feeding screw 233 is fixedly connected to the feeding motor 232. The feeding nut 234 is threadedly connected to the feeding screw 233 and fixedly connected to the feeding plate 235. The motor plate 236 is fixedly connected to the lifting slide plate 231. The proximity sensor 243 is disposed on one side of the feeding plate 235. The feeding motor 232 starts after receiving a signal from the controller 1 or the proximity sensor 243, driving the feeding screw 233 to rotate. Through the threaded engagement of the feeding nut 234 and the screw, the rotational motion is converted into linear motion, thereby driving the feeding plate 235 to rise or fall, achieving precise vertical material conveying and ensuring that the material is conveyed to the designated height for docking with the transfer mechanism 3. The lifting slide plate 231 is fixedly connected to the feeding slider 222 and can move synchronously with the sliding of the feeding adjustment component 22, allowing the lifting feeding component 23 to adapt to the position requirements of different materials. Simultaneously, the sliding connection between the lifting slide plate 231 and the feeding frame 21 ensures the stability of the lifting motion. The feeding motor 232 is electrically connected to the proximity sensor 243 and the controller 1, and can receive material detection signals from the proximity sensor 243 and commands from the controller 1 in real time. When the material reaches the designated position, it stops operating upon receiving the signal; when a material shortage is detected, it starts operating upon receiving a replenishment command, ensuring the continuity of material supply and preventing subsequent processes from being affected by material conveying interruptions.

[0037] In another embodiment of this utility model, the transfer and pushing assembly 31 includes a transfer and pushing cylinder 311, a transfer and pushing slider 312, and a transfer and pushing slide rail 313. The transfer and pushing cylinder 311 is connected to the sewing machine plate 423 of the sewing assembly 42 and is fixedly connected to the transfer and lifting cylinder 321 of the transfer and lifting assembly 32. The transfer and pushing slider 312 is slidably connected to the transfer and pushing slide rail 313 and is fixedly connected to the transfer and lifting cylinder 321 of the transfer and lifting assembly 32. The transfer and pushing slide rail 313 is fixedly connected to the sewing assembly 42. The transfer and lifting assembly 32 includes a transfer and lifting cylinder 321 and a cylinder pusher 322. The transfer and lifting cylinder 321 is fixedly connected to the transfer and pushing slider 312, and the cylinder pusher 322 is fixedly connected to the transfer and lifting cylinder 321. The transfer assembly 33 includes a transfer motor 331, a transfer frame 332, a first suction cup 333, and a second suction cup 334. The transfer motor 331 is fixedly connected to the cylinder pusher 322, and the transfer frame 332 is fixedly connected to the transfer motor 331 in the middle. One first suction cup 333 is provided and fixedly connected to the transfer frame 332. Two second suction cups 334 are provided, arranged parallel and spaced apart, and both are fixedly connected to the transfer frame 332. The size of the first suction cup 333 is larger than that of the second suction cup 334. The transfer frame 332 is located on one side of the loading plate 235. Through the extension and retraction drive of the transfer pushing cylinder 311, the transfer pushing slider 312 is driven to slide along the transfer pushing slide rail 313, thereby realizing the horizontal displacement adjustment of the transfer lifting assembly 32 and the transfer assembly 33. Its function is to push the transfer assembly 33 to the material picking position that docks with the loading plate 235, or to the material feeding position that docks with the sewing mechanism 4 fixture assembly 43, ensuring the accuracy of the material transfer path. When the transfer lifting cylinder 321 extends or retracts, it drives the cylinder pusher 322 and the transfer component 33 fixed thereon to rise or fall, thereby adjusting the vertical position of the transfer component 33. This action can adapt to the material picking position of the loading plate 235 and the material placement position of the fixture component 43 at different heights, ensuring that the suction cups can accurately contact the material and complete the gripping and placement. The transfer motor 331 drives the transfer frame 332 to rotate, flexibly adjusting the orientation of the suction cups to adapt to the material picking and placing angles; the first suction cup 333 and the second suction cup 334 use air pressure to adsorb the material. The transfer frame 332 is set on one side of the loading plate 235 and can quickly respond to the material picking command. After stably gripping the material on the loading plate 235, it is transferred to the fixture component 43 of the sewing mechanism 4 in conjunction with the transfer pushing component 31 and the transfer lifting component 32, completing the seamless connection of the material from the previous process to the next process.

[0038] In another embodiment of the present invention, the sewing assembly 42 includes a sewing machine head 421, a sewing needle 422, a sewing machine plate 423, a sewing cylinder 424, and a sewing pusher plate 425. The sewing machine head 421 is fixedly connected to the sewing machine frame 41, the sewing needle 422 is fixedly connected to the sewing machine head 421 and disposed above the fixture assembly 43, the sewing machine plate 423 is fixedly connected to the displacement fixing seat 441, the sewing cylinder 424 is fixedly connected to the fixture base plate 431, and the sewing pusher plate 425 is fixedly connected to the sewing cylinder 424 and disposed on one side of the fixture assembly 43. The fixture assembly 43 includes a fixture base plate 431 and a fixture plate. The fixture base plate 431 is fixedly connected to the sewing machine plate 423 and the displacement fixing seat 441, respectively. The fixture plate is mounted on the fixture base plate 431 and has a fixture groove. The sewing cylinder 424 is fixedly connected to the fixture base plate 431, and the sewing push plate 425 is fixedly connected to the fixture plate. The fixture plate includes a front fixture plate 432 and a rear fixture plate 433, both of which are mounted inside the fixture base plate 431. The top of the front fixture plate 432 is fixedly connected to the sewing push plate 425. Materials such as insoles are placed on the front fixture plate 432 and the rear fixture plate 433.

[0039] The sewing machine head 421 acts as a power source, driving the sewing needle 422 to reciprocate up and down, forming stitches on the surface of the material (such as an insole) to complete the sewing action. The sewing needle 422 is located above the fixture assembly 43, ensuring that it acts on the material at the position to be sewn. The sewing cylinder 424 drives the sewing push plate 425 to move linearly, pushing the fixture front plate 432 so that the fixture front plate 432 and fixture rear plate 433 cooperate to clamp the material, realizing the positioning and fixation of the material during the sewing process, preventing material displacement from affecting processing accuracy. The fixture base plate 431 is fixed on the sewing machine plate 423 and the displacement fixing seat 441, providing stable support for the fixture plate. The fixture plate consists of a fixture front plate 432 and a fixture rear plate 433, which together form a fixture groove structure. The material (such as an insole) is placed in the fixture groove, and the shape of the fixture groove is adapted to the material, which can play a preliminary limiting role for the material. The front plate 432 and the rear plate 433 of the fixture cooperate. Specifically, the top of the front plate 432 is connected to the sewing push plate 425. Under the action of the sewing cylinder 424, the front plate 432 can move relative to the rear plate 433 to clamp or release the material. This fixes the insole and effectively prevents the material from shifting during the sewing process.

[0040] In another embodiment of this utility model, the displacement assembly 44 includes a displacement fixing seat 441, a Y-axis slide rail 442, a Y-axis slider 443, an X-axis slide rail 444, an X-axis slider 445, and an X-axis slide plate 446. The displacement fixing seat 441 is fixedly connected to the sewing machine frame 41, the Y-axis slide rail 442 is fixedly connected to the displacement fixing seat 441, and the Y-axis slider 443 is slidably connected to the Y-axis slide rail 442. The X-axis slide rail 444 is fixedly connected to the Y-axis slider 443, the X-axis slider 445 is slidably connected to the X-axis slide rail 444, and is fixedly connected to the X-axis slide plate 446. The fixture base plate 431 is fixedly connected to the X-axis slide plate 446. The positions of the fixture base plate 431 and the fixture plate can be adjusted by the displacement assembly 44 to adjust different sewing positions of the insole.

[0041] The displacement fixing seat 441 provides stable support for the entire assembly, fixed to the sewing machine frame 41 to ensure overall structural stability. The Y-axis slide rail 442 cooperates with the Y-axis slider 443, allowing components such as the X-axis slide rail 444 connected to the Y-axis slider 443 to slide smoothly along the Y-axis, achieving position adjustment of the fixture assembly 43 in the Y-axis direction. The cooperation of the X-axis slide rail 444 and the X-axis slider 445 allows the X-axis slide plate 446 to drive the fixture base plate 431 and fixture plate to move along the X-axis, completing position adjustment in the X-axis direction. Through the coordinated adjustment of the X and Y axes, the fixture base plate 431 and fixture plate can flexibly move the insole on them to different positions, ensuring that the sewing needle 422 can be aligned with various sewing parts of the insole, meeting diverse sewing needs and improving sewing flexibility.

[0042] The automatic feeding sewing machine provided in this application operates as follows: First, the operator places the material on the feeding plate 235 of the feeding mechanism 2, and adjusts the position of the feeding slide plate 223 using the feeding adjustment component 22 to adapt to the material feeding requirements. The controller 1 activates the lifting feeding component 23, and the feeding motor 232 drives the feeding screw 233 to rotate, causing the feeding plate 235 to rise and convey the material upwards. When the material is conveyed to the detection range of the proximity sensor 243, the proximity sensor 243 detects the material and transmits a signal to the controller 1 and the feeding motor 232. The feeding motor 232 stops working, and the feeding plate 235 stops rising. The transfer mechanism 3 starts working, and the transfer pushing component 31 and the transfer lifting component 32 work together to adjust the position of the transfer component 33 so that the first suction cup 333 and the second suction cup 334 reach above the material, and the suction cups adsorb the material. The transfer motor 331 drives the transfer frame 332 to rotate, transferring the material into the fixture slot of the fixture component 43 of the sewing mechanism 4. When the proximity sensor 243 detects that the material on the feeding plate 235 is about to run out, it transmits a signal to the controller 1. The controller 1 then controls the lifting feeding assembly 23 to replenish the material in a timely manner, ensuring continuous feeding. After sewing is completed, all mechanisms reset, ready for the next feeding and sewing operation.

[0043] The automatic feeding sewing machine provided in this application can detect the presence of materials in real time by detecting the proximity sensor 243 in the feeding component 24, and promptly feed back the detection signal to the controller 1 and the lifting feeding component 23. When it is detected that the material is about to be short, the controller 1 can promptly control the lifting feeding component 23 to perform a material replenishment operation, which effectively avoids machine stagnation caused by material shortage, ensures the continuity of production, and improves production efficiency.

[0044] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
