Technical Field

[0001] This application relates to the technical field of sewing machine equipment, and in particular to a needle picking device for a sewing machine needle. Background Art

[0002] In garment production, workers need to use sewing machines for sewing processing. During the long-term sewing process, since the sewing machine needles are consumables, the needles may be damaged during long-term processing. Then, the damaged needles need to be removed by the workers and new needles need to be picked up for replacement. During the replacement process, the workers need to select new needles according to the lengths of different needles, and then recycle the damaged needles; However, currently, the above-mentioned replacement and recycling of needles mostly rely on manual operation. The workload during the recycling and needle replacement process is large and rather cumbersome, resulting in a reduction in the work efficiency of recycling and replacing needles and a waste of human resources; therefore, further improvements can be made. Summary of the Invention

[0003] In order to improve the work efficiency of recycling and replacing sewing machine needles, this application provides a needle picking device for a sewing machine needle.

[0004] A needle picking device for a sewing machine needle provided by this application adopts the following technical solution: A needle picking device for a sewing machine needle includes a chassis, on which a touch display screen, a face camera, a recycling mechanism, and a needle discharging mechanism are provided. Among them, the touch display screen and the face camera are arranged on the front of the chassis, and the face camera is arranged above the touch display screen. The needle discharging mechanism is arranged below the touch display screen. An out-needle platform is arranged below the needle discharging mechanism on the front of the chassis, and the needle discharging mechanism is arranged below the out-needle platform; The face camera is used to register the needle-changing staff; The touch display screen is used to control the face camera, the recycling mechanism, and the needle discharging mechanism to act respectively; The recycling mechanism is used to recycle the damaged needles of the staff; The needle discharging mechanism is used to send out the needles that the staff needs to replace; The out-needle platform is used to receive the new needles sent out by the needle discharging mechanism.

[0005] By adopting the above technical solution, when the staff needs to replace a damaged sewing needle, the damaged sewing needle is placed on the recycling mechanism, the touch display screen is activated, and the face camera is activated by the touch display screen to register the staff. Then, the recycling mechanism processes the damaged sewing needle. Finally, the sewing needle required by the staff is sent to the needle outlet platform through the needle outlet mechanism, and the staff takes the new sewing needle. Thus, the replacement and recycling of the damaged sewing needle are realized. Without manual participation, the needle replacement record of the staff can be automatically recorded, and the new sewing needle can be recycled and sent out, thereby improving the working efficiency of replacing the sewing needle.

[0006] Optionally, the recycling mechanism includes a recycling slot and a collection slot. The recycling slot is arranged below the needle outlet platform, and the collection slot is arranged below the recycling slot, and the collection slot is communicated with the recycling slot; At the top inside the recycling slot, there is a sewing needle recognition camera. At the bottom inside the recycling slot, there is a needle placing plate. A detection slot is formed on the needle placing plate, and the detection slot is communicated with the recycling slot. A detection plate is arranged in the detection slot. One side of the detection plate is provided with a recycling driving member, and the recycling driving member drives the detection plate to perform a contraction action in the detection slot, so as to convey the sewing needle on the detection plate into the collection slot through the detection slot; By adopting the above technical solution, during the process of replacing the sewing needle, the staff places the damaged sewing needle into the detection slot, and the sewing needle is photographed and recorded by the sewing needle recognition camera. Then, the recycling driving member retracts the detection plate, so that the damaged sewing needle is input from the detection slot into the collection slot. There is no need for manual collection, which reduces the occurrence of being stabbed by the sewing needle during the recycling process and reduces the situation of manual recording, thereby reducing the labor cost.

[0007] Optionally, at the top inside the collection slot, there are a first conveying plate and a second conveying plate. The first conveying plate is arranged above the second conveying plate. The top of the first conveying plate is arranged at the top inside the collection slot, and the top of the first conveying plate is inclined from the bottom towards the side wall of the collection slot; the top of the second conveying plate is arranged on the side wall of the collection slot, and the top of the second conveying plate is inclined from the top towards the first conveying plate. At the bottom of the collection slot, there is a collection box, and the collection box is located below the second conveying plate; when the damaged sewing needle is recycled, it slides from the first conveying plate to the second conveying plate in sequence, and then slides from the second conveying plate into the collection box for collection.

[0008] By adopting the above technical solution, the sewing needle dropped from the detection slot slides down through the inclined first conveying plate and the second conveying plate in sequence under the action of gravity, reducing the occurrence of stagnation and accumulation of the sewing needle during the recycling process and improving the recycling efficiency.

[0009] Optionally, the needle discharging mechanism includes a needle discharging bottom plate, on which a material placing seat for placing a plurality of machine needles is arranged. The material placing seats are arranged at intervals on the top of the needle discharging bottom plate. An discharging plate is arranged between the needle discharging bottom plate and the material placing seats. A first discharging slot for feeding a probe onto the needle discharging platform is formed on the needle discharging bottom plate. A second discharging slot for placing the machine needles to be discharged is formed on the discharging plate. An discharging driving component is arranged on the discharging plate. The discharging driving component drives the discharging plate to rotate on the needle discharging bottom plate, so that the second discharging slot communicates with the first discharging slot. A pushing component is arranged on the material placing seat for pushing the machine needles in the material placing seat towards the second discharging slot.

[0010] By adopting the above technical solution, the discharging driving component drives the discharging plate to rotate on the needle discharging bottom plate, so that the position of the second discharging slot with the machine needles moves until it communicates with the first discharging slot, and the machine needles fall from the second discharging slot through the first discharging slot onto the needle discharging platform, thus realizing the feeding of new machine needles.

[0011] Optionally, the material placing seat includes a main material placing plate and a sub-material placing plate. The main material placing plate is fixedly arranged on the top of the needle discharging bottom plate, and the bottom of the main material placing plate is spaced from the top of the needle discharging bottom plate. The sub-material placing plate is arranged at intervals on one side of the main material placing plate, and the sub-material placing plate is also spaced from the needle discharging bottom plate. The discharging plate is arranged between the needle discharging bottom plate and the main material placing plate and the sub-material placing plate. A needle receiving channel is formed between the main material placing plate and the sub-material placing plate for placing a plurality of machine needles. The pushing component is arranged on one side of the sub-material placing plate. When there is no needle taking action, the second discharging slot on the discharging plate communicates with the bottom of the needle receiving channel, so that the machine needle at the bottom of the needle receiving channel can be placed in the second discharging slot.

[0012] By adopting the above technical solution, the staff places a plurality of new machine needles into the needle receiving channel between the main material placing plate and the sub-material placing plate, and under the action of the pushing component, pushes the machine needle at the bottom of the needle receiving channel into the second discharging slot. Then, under the action of the discharging driving component, the discharging plate is driven to rotate, and the second discharging slot is moved above the first discharging slot and communicated with the first discharging slot, so as to output the machine needles from the first discharging slot.

[0013] Optionally, the discharging driving assembly includes a discharging driving member fixedly arranged at the end of the needle discharging bottom plate away from the material placing seat, with the movable end of the discharging driving member facing one end of the material placing seat. A connecting block is arranged on the movable end of the discharging driving member, and a movable slider is arranged through the connecting block. A movable clamping seat is arranged on the connecting block, and the connecting block is slidably arranged on the upper and lower sides inside the movable clamping seat. Movable sliding grooves are formed on the upper and lower sides inside the movable clamping seat, and both ends of the movable slider extend outwards from the connecting block into the movable sliding grooves. The top of the movable clamping seat is fixedly arranged at the bottom of the discharging plate. A rotating shaft is arranged between one end of the discharging plate and the needle discharging bottom plate, so that when the discharging driving member drives the connecting block to perform a telescopic action, the movable slider on the connecting block slides in the movable sliding grooves on the movable clamping seat. Since one end of the discharging plate uses the rotating shaft as the center point, the telescopic connecting block drives the movable clamping seat and the discharging plate to rotate, thereby realizing the transfer of the second discharging groove on the discharging plate to the first discharging groove for communicating and discharging needles.

[0014] By adopting the above technical solution, when the discharging plate rotates, with the rotating shaft between the discharging plate and the needle discharging bottom plate as the center point, and driven by the discharging driving member, the movable slider on the connecting block moves in the movable sliding grooves inside the movable clamping seat, thereby driving the movable clamping seat and the discharging plate to rotate around the rotating shaft, and rotating to above the first discharging groove and communicating, so as to realize the transfer of the machine needles in the needle receiving channel.

[0015] Optionally, a reset member is arranged on the needle discharging bottom plate. The reset member includes a fixed rod, a rotating rod and a reset spring. The fixed rod is fixedly arranged on the top of the needle discharging bottom plate, the rotating rod is fixedly arranged on the top of the discharging plate, and both ends of the reset spring are fixedly arranged on the fixed rod and the rotating rod respectively. When the discharging driving member drives the discharging plate to rotate, the rotating rod connected to the discharging plate also moves, so that the reset spring deforms. When the discharging plate is reset by the discharging driving member, the deformed reset spring returns to its original state to assist the discharging plate in resetting.

[0016] By adopting the above technical solution, during the rotation of the discharging plate, the rotating rod connected to the fixed plate also moves. During the movement, the rotating rod is driven to displace, and during the displacement, the reset spring also deforms following the rotating rod. When the discharging plate is reset, the deformed reset spring returns to its original state, thereby realizing the auxiliary reset of the discharging plate.

[0017] Optionally, a first limiting block and a second limiting block are respectively arranged on both sides of the top of the needle discharging bottom plate, and the discharging plate is arranged between the first limiting block and the second limiting block. The rotation of the discharging plate is limited by the first limiting block and the second limiting block to limit the movement range of the discharging plate.

[0018] By adopting the above technical solution, the first limiting block and the second limiting block are used to limit the two sides of the rotatable discharge plate respectively, restricting the movement range of the discharge plate. Thus, by controlling the movement range of the discharge plate, it is ensured that the path of the discharge plate moving under the action of the discharge driving member is accurate, thereby ensuring the connection between the first discharge groove and the second discharge groove.

[0019] Optionally, a buffer pad made of an elastic material is laid on the top of the needle discharging platform for buffering when the sewing needle in the needle discharging mechanism drops onto the needle discharging platform.

[0020] By adopting the above technical solution, the buffer pad is used to buffer the sewing needle that drops from the needle discharging mechanism onto the needle discharging platform, reducing the impact of the sewing needle under the action of gravity and protecting the sewing needle from damage when it falls onto the buffer pad.

[0021] Optionally, moving wheels for driving the chassis to move are provided at the bottom of the chassis.

[0022] By adopting the above technical solution, the moving wheels enable the chassis to be transferred to a suitable position according to the needs of the user, increasing the flexibility of the chassis, making the movement of the chassis more stable, reducing the risk of accidents caused by improper movement of the equipment, and improving the work safety.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the staff needs to replace a damaged sewing needle, the damaged sewing needle is placed on the recycling mechanism, the touch display screen is started, and the face camera is started by using the touch display screen to register the staff. Then, the recycling mechanism recycles the damaged sewing needle. Finally, the sewing needle required by the staff is sent to the needle discharging platform by the needle discharging mechanism, and the staff takes away the new sewing needle. Thus, the replacement and recycling of the damaged sewing needle are realized. Without human participation, the replacement record of the needle-changing staff can be automatically recorded, and the new sewing needle can be recycled and sent out, thereby improving the working efficiency of replacing the sewing needle; 2. When the discharge plate rotates, with the rotation axis between the discharge plate and the needle discharging bottom plate as the center point, and driven by the discharge driving member, the moving slider on the connecting block moves in the moving chute inside the moving clamp seat, thereby driving the moving clamp seat and the discharge plate to rotate around the rotation axis, and rotating to above the first discharge groove and connecting, so as to realize the transfer of the sewing needle in the needle receiving channel; 3. During the rotation of the discharge plate, the rotating rod connected to the fixed plate also moves. During the movement, the rotating rod generates a displacement. During the displacement, the reset spring also deforms following the rotating rod. When the discharge plate resets, the deformed reset spring returns to its original state, thereby realizing the auxiliary reset of the discharge plate; 4. The two sides of the rotatable discharge plate are respectively limited by the first limiting block and the second limiting block to restrict the movement range of the discharge plate. By controlling the movement range of the discharge plate, it is ensured that the path of the discharge plate moving under the action of the discharge driving member is accurate, thereby ensuring the connection between the first discharge slot and the second discharge slot.

Specific Embodiment

[0032] The following will further elaborate on this application Figure 1-7 in conjunction with the accompanying drawings.

[0033] An embodiment of this application discloses a needle picking device for a sewing machine needle.

[0034] Referring to Figure 1 , a needle picking device for a sewing machine needle includes a chassis 1. Above the front of the chassis 1, a touch display screen 2 is fixedly arranged. On both sides of the touch display screen 2, recycling prompt speakers are provided. Above the touch display screen 2, a face camera 3 is provided; Below the touch display screen 2 on the chassis 1, a needle placement groove 11 is opened. An out-needle mechanism 4 is arranged in the needle placement groove 11. On the side of the needle placement groove 11 away from the inner side wall of the chassis 1, a transparent observation door is provided. At the bottom of the chassis 1 where the needle placement groove 11 is located, a needle output platform 6 is provided. The bottom of the needle placement groove 11 is in communication with the needle output platform 6. Below the needle output platform 6 on the chassis 1, a recycling mechanism 5 is provided.

[0035] During the actual process of changing the sewing machine needle, the damaged sewing machine needle is placed on the recycling mechanism 5. The touch display screen 2 is activated, and the face camera 3 is activated by the touch display screen 2 to register the staff. Then, the recycling mechanism 5 processes the recycling of the damaged sewing machine needle. Finally, the sewing machine needle required by the staff is sent to the needle output platform 6 through the out-needle mechanism 4, and the staff takes away the new sewing machine needle. Thus, the replacement and recycling of the damaged sewing machine needle are realized. Without manual participation, the needle change record of the needle-changing staff can be automatically recorded, and the new sewing machine needle can be recycled and sent out, thereby improving the working efficiency of changing the sewing machine needle.

[0036] Referring to Figure 1 , 2 , specifically, in this embodiment, the recycling mechanism 5 includes a recycling groove 51 and a collection groove 52. The recycling groove 51 is arranged below the needle output platform 6, and the collection groove 52 is arranged below the recycling groove 51, and the collection groove 52 is in communication with the recycling groove 51. On the side of the collection groove 52 away from the inner side wall of the chassis 1, a transparent recycling door is provided; At the top inside the recycling groove 51, a needle recognition camera 53 is arranged. At the bottom inside the recycling groove 51, a needle placement plate 54 is arranged. The needle placement plate 54 is directly below the needle recognition camera 53 for the needle camera to recognize; A detection groove 55 is provided along the length direction of the needle placing plate 54. A recovery channel 56 is opened between the detection groove 55 and the collection groove 52 in the chassis 1. The detection groove 55 and the collection groove 52 are interconnected through the recovery channel 56. A detection plate 58 is arranged in the detection groove 55. A recovery driving part 57 is arranged on the side of the detection plate 58 close to the chassis 1. The movable end of the recovery driving part 57 is fixedly connected to the detection plate 58 and drives the detection plate 58 to perform a contraction action in the detection groove 55. Before contraction, the detection plate 58 separates the detection groove 55 from the recovery channel 56, so that the damaged machine needles are placed on the top of the detection plate 58. After the recording is completed, the recovery driving part 57 contracts, pulling the detection plate 58 out of the detection groove 55. After the machine needles on the detection plate 58 are blocked by the side wall of the detection groove 55, they fall into the collection groove 52 through the recovery channel 56.

[0037] During the process of changing the machine needles, the staff places the damaged machine needles into the detection groove 55, takes pictures and records the machine needles through the machine needle recognition camera 53. Then the recovery driving part 57 retracts the detection plate 58, so that the damaged machine needles are input from the detection groove 55 into the collection groove 52, eliminating the need for manual collection, reducing the occurrence of being pricked by the machine needles during the recovery process, and reducing the situation of manual recording, thereby reducing the labor cost.

[0038] Refer to Figure 1 、 2 Specifically, in this embodiment, a first conveying plate 521 and a second conveying plate 522 are arranged in the collection groove 52. The first conveying plate 521 is arranged above the second conveying plate 522, and both the first conveying plate 521 and the second conveying plate 522 are arranged obliquely. The top of the first conveying plate 521 is arranged at the inner top of the collection groove 52, and the top of the first conveying plate 521 is inclined from the bottom towards the side wall of the collection groove 52; the top of the second conveying plate 522 is arranged at the side wall of the collection groove 52, and the top of the second conveying plate 522 is inclined from the top towards the first conveying plate 521. A collection box 523 is arranged at the bottom of the collection groove 52, and the collection box 523 is located below the second conveying plate 522; when the damaged machine needles are recovered, they slide from the first conveying plate 521 to the second conveying plate 522 in sequence, and then slide from the second conveying plate 522 into the collection box 523 for collection.

[0039] During the actual use process, the machine needles falling from the detection groove 55 slide down through the inclined first conveying plate 521 and second conveying plate 522 under the action of gravity, reducing the occurrence of stagnation and accumulation of the machine needles during the recovery process and improving the recovery efficiency.

[0040] Refer to Figure 1 、 3, 4. Specifically, in this embodiment, the needle discharging mechanism 4 includes a needle discharging bottom plate 41. There are several needle discharging bottom plates 41, which are divided into two groups. The two groups of needle discharging bottom plates 41 are respectively arranged at intervals on the inner bottom of the needle placing groove 11. A material placing seat 42 is fixedly arranged on the top of the needle discharging bottom plate 41. The material placing seat 42 is used to place a number of machine needles. The bottom of the material placing seat 42 is arranged at intervals on the top of the needle discharging bottom plate 41. A discharging plate 43 is arranged between the needle discharging bottom plate 41 and the material placing seat 42. The discharging plate 43 is rotatably arranged on the needle discharging bottom plate 41. A first discharging groove 44 for feeding the probe into the needle discharging platform 6 is formed on the needle discharging bottom plate 41. A second discharging groove 45 for placing the machine needles to be discharged is formed on the discharging plate 43. The discharging plate 43 can rotate to communicate the second discharging groove 45 with the first discharging groove 44; A discharging driving assembly 46 is arranged on the discharging plate 43. The discharging driving assembly 46 drives the discharging plate 43 to rotate on the needle discharging bottom plate 41, so that the second discharging groove 45 is communicated with the first discharging groove 44. A pushing assembly 47 for pushing the machine needles in the material placing seat 42 towards the second discharging groove 45 is arranged on the material placing seat 42.

[0041] In addition, a number of control buttons 61 are arranged on the top of the needle discharging platform 6 along its length direction. The number of control buttons 61 is the same as the number of material placing seats 42. When the touch display screen 2 fails to work properly, the discharging driving assembly 46 can also be controlled by the control buttons 61 to send out the machine needles.

[0042] In the actual use process, the discharging driving assembly 46 is used to drive the discharging plate 43 to rotate on the needle discharging bottom plate 41, so that the position of the second discharging groove 45 with the machine needles moves until it moves to be communicated with the first discharging groove 44, and the machine needles fall from the second discharging groove 45 through the first discharging groove 44 onto the needle discharging platform 6, thus realizing the sending out of new machine needles.

[0043] Refer to Figure 3 , specifically, in this embodiment, a first limiting block 411 and a second limiting block 412 are respectively arranged on both sides of the top of the needle discharging bottom plate 41 along its width direction. The discharging plate 43 is arranged between the first limiting block 411 and the second limiting block 412. The first limiting block 411 is arranged on the side close to the first discharging groove 44, and the second limiting block 412 is arranged on the side close to the first limiting groove.

[0044] In the actual use process, the two sides of the rotatable discharging plate 43 are respectively limited by the first limiting block 411 and the second limiting block 412, and the moving range of the discharging plate 43 is restricted. Thus, by controlling the moving range of the discharging plate 43, it is ensured that the moving path of the discharging plate 43 under the action of the discharging driving member 461 is accurate, so as to ensure the communication between the first discharging groove 44 and the second discharging groove 45.

[0045] Refer toFigure 1 Specifically, in this embodiment, the material feeding base 42 includes a main material feeding plate 421 and a secondary material feeding plate 422 that are rectangular. The main material feeding plate 421 and the secondary material feeding plate 422 are spaced apart from each other. The spaced space between the main material feeding plate 421 and the secondary material feeding plate 422 forms a needle receiving channel 425 for placing a number of sewing needles. One side of the main material feeding plate 421 is fixedly arranged above the middle of the second limiting block 412 through bolts, so as to realize the spaced arrangement between the bottom of the main material feeding plate 421 and the top of the needle outlet bottom plate 41. The secondary material feeding plate 422 is spaced apart from the main material feeding plate 421 by bolts on the side away from the second limiting block 412, and is also spaced apart from the top of the needle outlet bottom plate 41. The material discharging plate 43 is arranged between the top of the needle outlet bottom plate 41 and the bottoms of the main material feeding plate 421 and the secondary material feeding plate 422; The pushing component 47 is arranged on the side of the secondary material feeding plate 422 away from the main material feeding plate 421. When there is no needle taking action, the second material discharging groove 45 on the material discharging plate 43 is communicated with the bottom of the needle receiving channel 425, so that the sewing needle at the bottommost part in the needle receiving channel 425 can be placed into the second material discharging groove 45; In order to place a number of sewing needles, on the opposite sides of the main material feeding plate 421 and the secondary material feeding plate 422, the needle receiving channel 425 is opened along the height direction of the main material feeding plate 421, and the width of the needle receiving channel 425 gradually shrinks from top to bottom until it just accommodates the sewing needle, so that the sewing needles fall one by one in the needle receiving channel 425 under the action of gravity.

[0046] During actual use, the staff places a number of new sewing needles into the needle receiving channel 425 between the main material feeding plate 421 and the secondary material feeding plate 422, and under the action of the pushing component 47, pushes the sewing needle at the bottommost part in the needle receiving channel 425 into the second material discharging groove 45. Then, under the action of the material discharging driving component 46, the material discharging plate 43 is driven to rotate, and the second material discharging groove 45 is moved above the first material discharging groove 44 and communicated with the first material discharging groove 44, so as to output the sewing needle from the first material discharging groove 44.

[0047] Refer to Figure 4 、 5, Specifically, in this embodiment, the pushing component 47 includes a sinking seat 471. The sinking seat 471 can slide up and down along the height direction of the secondary discharging plate 422. To achieve the sliding, a secondary lifting chute 423 is formed along the height direction on the side of the secondary discharging plate 422 away from the main discharging plate 421. And a through groove is formed along the height direction on the side of the secondary lifting chute 423 close to the main discharging plate 421. A main lifting chute 424 is formed along the height direction on the side of the main discharging plate 421 close to the secondary discharging plate 422. Correspondingly, a dovetail-shaped lifting slider 472 is arranged on the side of the sinking seat 471 close to the secondary discharging plate 422. A pressing piece 473 is arranged at the bottom of the side of the lifting slider 472 close to the main discharging plate 421. The pressing piece 473 passes through the through groove. A dovetail-shaped lifting sliding piece 474 is arranged at one end of the pressing piece 473 close to the main discharging plate 421. The lifting slider 472 is slidably arranged in the secondary lifting chute 423, and the lifting sliding piece 474 is slidably arranged in the main lifting chute 424. And the pressing piece 473 connected to the lifting slider 472 and the lifting sliding piece 474 at both ends can perform a lifting action in the needle receiving channel 425 following the lifting slider 472 and the lifting sliding piece 474. The pressing piece 473 is always located at the top of the uppermost knitting needle in the needle receiving channel 425 to press it down; In addition, an observation piece is arranged along the length direction at the bottom of the sinking seat 471. The observation piece is always flush with the uppermost knitting needle in the needle receiving channel 425, so that the staff can observe the number of knitting needles in the needle receiving channel 425 to judge whether it is necessary to replenish the knitting needles.

[0048] During the actual use process, when the lowermost knitting needle in the needle receiving channel 425 is transferred by the discharging plate 43, the second-lowest knitting needle drops, and the other knitting needles also drop under the action of gravity during the movement. During the movement, the pressing piece 473 also moves downward to press the uppermost knitting needle in the needle receiving channel 425 to assist its downward movement and avoid the occurrence of needle jamming.

[0049] Refer to Figure 4 、 6, 7. Specifically, in this embodiment, the discharging driving assembly 46 includes a discharging driving member 461. The discharging driving member 461 is fixedly arranged at the end of the needle discharging bottom plate 41 away from the feeding seat 42. The movable end of the discharging driving member 461 faces one end of the feeding seat 42 and penetrates through the feeding seat 42. A connecting block 462 is arranged on the movable end of the discharging driving member 461. A cylindrical moving slider 463 is arranged on the connecting block 462 in a through manner from top to bottom. A U-shaped moving clamping seat 464 is arranged on the connecting block 462. The connecting block 462 is slidably arranged on the upper and lower sides inside the moving clamping seat 464. Curved moving chutes 465 are respectively arranged on the upper and lower sides inside the moving clamping seat 464. The two ends of the moving slider 463 extend outwards from the connecting block 462 into the moving chutes 465. The top of the moving clamping seat 464 is fixedly arranged at the bottom of the discharging plate 43. A rotating shaft 466 is arranged between one end of the discharging plate 43 and the needle discharging bottom plate 41. When the discharging driving member 461 drives the connecting block 462 to perform a telescopic action, the moving slider 463 on the connecting block 462 slides in the moving chutes 465 on the moving clamping seat 464. Since one end of the discharging plate 43 uses the rotating shaft 466 as the center point, the telescopic connecting block 462 drives the moving clamping seat 464 and the discharging plate 43 to rotate, so as to transfer the second discharging groove 45 on the discharging plate 43 to the first discharging groove 44 for connecting and discharging needles.

[0050] During the actual use process, when the discharging plate 43 rotates, with the rotating shaft 466 between the discharging plate 43 and the needle discharging bottom plate 41 as the center point, and driven by the discharging driving member 461, the moving slider 463 on the connecting block 462 moves in the moving chutes 465 inside the moving clamping seat 464, thereby driving the moving clamping seat 464 and the discharging plate 43 to rotate around the rotating shaft 466, and rotating to above the first discharging groove 44 and connecting, so as to transfer the machine needles in the needle receiving channel 425.

[0051] Refer to Figure 6 , 7 , specifically, in this embodiment, a reset member 7 is arranged on the needle discharging bottom plate 41. The reset member 7 includes a fixed rod 71, a rotating rod 72 and a reset spring 73. The fixed rod 71 is fixedly arranged on the top of the needle discharging bottom plate 41. The rotating rod 72 is fixedly arranged at one end of the top of the discharging plate 43 away from the rotating shaft 466. The two ends of the reset spring 73 are respectively fixedly arranged on the fixed rod 71 and the rotating rod 72. When the discharging driving member 461 drives the discharging plate 43 to rotate, the rotating rod 72 connected to the discharging plate 43 also moves, so that the reset spring 73 deforms. When the discharging plate 43 is reset by the discharging driving member 461, the deformed reset spring 73 returns to its original state to assist the discharging plate 43 to reset.

[0052] During actual use, when the discharge plate 43 rotates, the rotating rod 72 connected to the fixed plate also moves. During the movement, the rotating rod 72 is displaced. During the displacement process, the return spring 73 also deforms following the rotating rod 72. When the discharge plate 43 returns to its original position, the deformed return spring 73 returns to its original state, thereby assisting the discharge plate 43 to return to its original position.

[0053] Referring to Figure 1 , specifically, in this embodiment, a buffer pad 62 made of an elastic material is laid on the top of the needle-out platform 6 for the sewing needle in the needle-out mechanism 4 to fall onto the needle-out platform 6 and be buffered by the buffer pad 62. The buffer pad 62 buffers the sewing needle that falls from the needle-out mechanism 4 onto the needle-out platform 6, reducing the impact of the sewing needle under the action of gravity and protecting the sewing needle from damage when it falls onto the buffer pad 62.

[0054] Referring to Figure 1 , specifically, in this embodiment, moving wheels 8 for driving the chassis 1 to move are provided at the bottom of the chassis 1. The moving wheels 8 enable the chassis 1 to be transferred to a suitable position according to the user's needs, increasing the flexibility of the chassis 1, making the movement of the chassis 1 more stable, reducing the risk of accidents caused by improper movement of the equipment, and improving work safety.

[0055] The implementation principle of the needle-taking device for a sewing machine needle in an embodiment of this application is as follows: The staff places the damaged sewing needle into the detection slot 55, and the sewing needle is photographed and recorded by the sewing needle recognition camera 53. Then, the recovery driving member 57 retracts the detection plate 58, so that the damaged sewing needle is input from the detection slot 55 through the first conveying plate 521 and the second conveying plate 522 into the collection box 523 in the collection tank 52 for recovery. At the same time, the touch display screen 2 is used to control the operation of the needle-out mechanism 4, and the discharge driving assembly 46 drives the discharge plate 43 to rotate on the needle-out bottom plate 41, so that the position of the second discharge slot 45 with the sewing needle moves until it moves to communicate with the first discharge slot 44, and the sewing needle falls from the second discharge slot 45 through the first discharge slot 44 onto the needle-out platform 6, thereby realizing the delivery of a new sewing needle.
