Description

Technical Field

[0001] This invention relates to the field of sewing machines, and more particularly to a sewing machine and an improved sewing machine table thereof. Background Technology

[0002] In the manufacturing process of plush toys, sewing machines are one of the indispensable processing tools. With the development of sewing technology, the types of sewing machines are constantly increasing, with different functions, forming a relatively complete product system, and are applied to different processing scenarios according to their respective characteristics.

[0003] In the toy manufacturing process, the main method is to sew the fabric outer layer of the toy together using a sewing machine. For some toys, buttons also need to be sewn onto the outer layer, such as for realistic clothing. Specially designed buttons can also serve a decorative purpose. When sewing buttons, they are placed on the toy's outer layer. Each button has at least two sewing holes. The sewing machine then wraps the thread back and forth between the two sewing holes to connect the button to the outer layer.

[0004] Regarding the aforementioned techniques, when sewing buttons, it is necessary to fix the position of the buttons. Although sewing machines usually have a pressure plate at the sewing needle, which can be used to clamp the buttons and outer skin when sewing buttons, the operator still needs to actively pick up the buttons one by one and place them under the pressure plate during the sewing process. Picking up the buttons takes time, and the operation is quite cumbersome when sewing a large number of buttons. Summary of the Invention

[0005] To improve the convenience of sewing buttons onto toy covers, this application provides a sewing machine and an improved sewing machine table thereof.

[0006] In a first aspect, this application provides a sewing machine, which adopts the following technical solution: A sewing machine includes a frame, on which a sewing needle and a pressure plate are disposed. The pressure plate is slidably connected to the frame vertically. A storage box is fixedly connected to the lower end of the frame. A material feed groove is vertically formed inside the storage box. A material outlet is formed on the lower end of the storage box near the sewing needle. The material outlet is horizontally formed and communicates with the material feed groove. Two parallel feed rods are slidably connected to the storage box horizontally, and a drive cylinder is provided for moving the feed rods. A support plate is fixedly connected between the two feed rods. The lower end of each feed rod has an abutment piece facing the support plate. The lower end of the support plate has a clamping piece. The clamping piece has guide surfaces along its circumference, with the guide surfaces extending from bottom to top. The clamping plate is deflected outward from the center. An elastic element is provided between the clamping plate and the bearing plate. The elastic element is used to push the clamping plate closer to the abutment plate. Two positioning plates are provided vertically inside the discharge port. Both positioning plates are rotatably connected to the placement box in the horizontal direction. Positioning grooves are opened on the side of the two positioning plates that are close to each other. The positioning grooves are directly opposite the button at the bottom of the feeding groove. The placement box is provided with a pusher for pushing the button from the feeding groove to the positioning groove. The placement box is fixedly connected with a stop block corresponding to the positioning plate. The stop block is located on the side of the positioning plate that is close to the bearing plate. An elastic element is provided between the positioning plate and the placement box. The elastic element is used to push the positioning plate closer to the stop block.

[0007] By adopting the above technical solution, when sewing buttons, the toy's outer skin is placed under the pressure plate and sewing needle. Several buttons are pre-placed in the feed chute of the storage box, and these buttons are arranged vertically under gravity. When a button needs to be placed, the pusher first conveys the bottom button to the positioning groove. At this time, the positioning plate, under the action of the elastic element two, abuts against the stop block. All positioning plates cooperate to limit the button's position through the positioning groove. After the pusher resets, the buttons in the feed chute continue to fall, leaving two buttons side-by-side at the bottom of the storage box. The drive cylinder moves the feed rod, which in turn moves the support plate towards the feed inlet. When the support plate, along with the clamping plate and the abutment plate, contacts the positioning plate, it pushes the positioning plate away from the stop block. At this point, the button in the positioning groove is blocked by the button at the lower end of the feed groove and is pressed between the clamping plate and the abutment plate along the guide surface. The clamping plate then compresses the elastic element, and under the action of the elastic element, the clamping plate and the abutment plate work together to clamp the button. The drive cylinder then moves the feed rod towards the sewing needle, thus delivering the button below the pressure plate. This saves the operator time in retrieving the button and improves the convenience of sewing buttons onto toy skins.

[0008] Optionally, the pusher includes a top block, an elastic element three, and a pusher block. The lower end of the placement box has a receiving groove communicating with the feeding groove. The top block is located in the receiving groove and is slidably connected to the placement box along the length of the feeding rod. The lowest button of the feeding groove is located between the top block and the positioning plate. The pusher block is fixedly connected to the end of the feeding rod away from the bearing plate and is located on the side of the placement box away from the sewing needle. The placement box has a through groove communicating with the receiving groove. The pusher block is directly opposite the through groove. The elastic element three is located between the pusher block and the placement box and is used to drive the pusher block away from the positioning plate.

[0009] By adopting the above technical solution, in the initial state, the top block is located in the receiving groove. When the feeding rod drives the bearing plate to deliver the button below the sewing needle, the feeding rod drives the pushing block to move towards the top block and abuts against the top block through the through groove. Under the action of the pushing block, the top block moves out of the receiving groove and pushes the button at the lower end of the feed chute towards the positioning groove. At this time, the elastic element deforms. When the feeding rod resets, the elastic element drives the top block to reset, and the button in the feed chute continues to fall.

[0010] Optionally, the lower end of the placement box is provided with a support block, and the lower end of the placement box is provided with a movable groove communicating with the discharge port. The support block is located in the movable groove and is slidably connected to the placement box along the length of the feeding rod. The height of the upper surface of the support block is lower than the bottom surface of the feeding groove. Among the two positioning plates, the positioning plate located at the lower end is provided with a connecting rod between it and the support block. One end of the connecting rod is hinged to the support block, and the other end is hinged to the positioning plate.

[0011] By adopting the above technical solution, when the pusher conveys the button at the lower end of the feed chute to the positioning groove, the button moves along the side wall of the bottom surface of the feed chute towards the upper end of the support block. After the button enters the positioning groove, it falls above the support block under the action of gravity. When the clamping plate and the abutment plate push the positioning plate to rotate, the positioning plate drives the support block to avoid the clamping plate and the abutment plate through the connecting rod. When the positioning plate rotates, it pushes the button in the positioning groove closer to the feed chute. When the positioning plate rotates to an appropriate angle, it separates from the button. At this time, the clamping plate contacts the button and limits the button through the discharge port near the side wall of the feed chute, so that the button enters between the clamping plate and the abutment plate, which helps to improve the convenience of the button squeezing into the clamping plate and the abutment plate.

[0012] Optionally, the feeding rod is slidably connected to a moving rod along its length. One end of the moving rod extends to the lower end of the support plate. A baffle is fixedly connected to the end of the moving rod away from the top plate. The baffle is located on the side of the placement box away from the sewing needle. A sliding groove is provided along the length of the feeding rod. The baffle passes through the sliding groove and extends in the opposite direction away from the moving rod. An elastic element four is provided between the moving rod and the feeding rod. The elastic element four is used to drive the top block support plate closer. The abutment piece is slidably connected to the feeding rod in the lateral direction. A connecting block is fixedly connected to the lower end of the moving rod. A hinge rod is provided between the connecting block and the abutment piece. One end of the hinge rod is hinged to the connecting block, and the other end is hinged to the abutment piece.

[0013] By adopting the above technical solution, in the initial state, when the clamping plate clamps the button, the moving rod is positioned close to the bearing plate under the action of the elastic element four. At this time, the abutment plate is located below the pressing plate. When the clamping plate moves the button closer to the sewing needle, the baffle contacts the placement box. At this time, the feeding rod continues to move, and then under the action of the baffle, the moving rod and the feeding rod move relative to each other. Then, the abutment plate is moved through the hinge rod, so that the abutment plate avoids the button. At this time, the button is separated from the abutment plate and the clamping plate and falls on the outer skin of the toy, completing the automatic feeding of the button, which helps to further improve the convenience of sewing buttons.

[0014] Optionally, the material feeding trough is provided with a guide frame, and the placement box is provided with an installation groove adapted to the guide frame. The guide frame is located in the installation groove and is slidably connected to the placement box in the vertical direction. Both sides of the guide frame are provided with arc-shaped plates in the width direction. The guide frame is provided with an adjustment component that drives the two arc-shaped plates to move closer or further apart.

[0015] By adopting the above technical solution, the placement box limits the guide frame through the mounting groove. When placing a button, the button is placed between two arc-shaped plates, allowing the guide frame to limit the button through the two arc-shaped plates, reducing the probability of the button flipping over in the feed chute. The distance between the two arc-shaped plates can be adjusted by the adjusting component, thus making the arc-shaped plates suitable for buttons of different sizes.

[0016] Optionally, each of the two arc-shaped plates has a movable block slidably connected along its length on one side that is close to the other. A counterweight plate is vertically hinged to the end of the movable block away from the arc-shaped plate. A rotating rod is vertically provided on the arc-shaped plate and is rotatably connected to the arc-shaped plate. A support plate is vertically fixed at the lower end of the rotating rod and is located at the lower end of the arc-shaped plate.

[0017] By adopting the above technical solution, when the pallet is directly below the curved plate, it supports the buttons between the two curved plates, thus facilitating the movement of all buttons via the guide frame. When it is necessary to move the buttons between the two curved plates towards the discharge port, the rotating rod is rotated, causing the pallet to avoid the buttons. The counterweight plate and the moving block are both located above all the buttons, used to push the buttons along the curved plate, thereby further reducing the probability of the buttons shifting between the two curved plates.

[0018] Optionally, the lower end of the pressing plate is provided with a circular groove, and a number of positioning rods are provided in the circular groove. The positioning rods are fixedly connected to the pressing plate vertically. Elastic blocks are fixed on both sides of the placement box along the length of the feed port. The distance between two elastic blocks gradually decreases along the direction of the feed rod pointing to the sewing needle, and any one of the elastic blocks is provided with anti-slip texture along the length direction.

[0019] By adopting the above technical solution, when the button enters between the clamping plate and the abutment plate, it is located in the circular groove. The number and position of the positioning rods are set according to the number and position of the button's sewing holes. When the positioning rod is aligned with the sewing hole, the positioning rod is inserted into the sewing hole. When the positioning rod is not aligned with the sewing hole, when the clamping plate moves the button closer to the sewing needle, the button contacts the elastic block and rotates under the action of the anti-slip texture. When the button rotates to the point where the sewing hole is aligned with the positioning rod, the clamping plate, under the action of the elastic element, moves the positioning rod into the sewing hole. The position of the positioning rod remains unchanged. Therefore, when sewing the button, there is no need to readjust the button according to the position of the sewing hole.

[0020] Secondly, this application provides an improved sewing machine table, which adopts the following technical solution: An improved sewing machine table is provided, which is located at the lower end of the machine frame. A slot is provided at the upper end of the table, and a support block is provided in the slot. A limiting groove for limiting the button is provided on the upper surface of the support block, and the limiting groove is located directly below the sewing needle.

[0021] By adopting the above technical solution, the platform limits the support block through the slot. When sewing the button, the toy skin is placed on top of the support block. When the button is placed, it is located above the limiting hole. When the button is pressed by the pressing plate, the button drives the skin into the limiting groove, thereby limiting the button and reducing the probability of button deviation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When sewing buttons, place the toy's outer skin under the pressure plate and sewing needle. Simultaneously, pre-place several buttons in the feed chute of the storage box. These buttons are arranged vertically under gravity. When a button needs to be placed, the pusher first feeds the bottom button towards the positioning groove. At this time, the positioning plate, under the action of the elastic element, abuts against the stop block. All positioning plates cooperate to limit the button's position through the positioning groove. After the pusher resets, the buttons in the feed chute continue to fall, leaving two buttons side-by-side at the bottom of the storage box. The drive cylinder moves the feed rod, which in turn moves the support plate towards the feed port. When the support plate, along with the clamping plate and the abutment piece, contacts the positioning plate, it pushes the positioning plate away from the stop block. At this point, the button in the positioning groove is blocked by the button at the lower end of the feed groove and is pressed between the clamping plate and the abutment piece along the guide surface. The clamping plate then compresses the elastic element, and under the action of the elastic element, the clamping plate and the abutment piece work together to clamp the button. The drive cylinder then moves the feed rod towards the sewing needle, thus delivering the button below the pressure plate. This saves the operator time in retrieving the button and improves the convenience of sewing buttons onto toy skins. 2. Initially, the top block is located in the receiving groove. When the feed rod moves the support plate to deliver the button below the sewing needle, the feed rod drives the push block to move towards the top block and abuts against the top block through the through groove. Under the action of the push block, the top block moves out of the receiving groove and pushes the button at the lower end of the feed chute towards the positioning groove. At this time, the elastic element deforms. When the feed rod resets, the elastic element drives the top block to reset, and the button in the feed chute continues to fall.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a sewing machine.

[0032] Example: Reference Figure 1 and Figure 2 A sewing machine includes a frame 1. A sewing needle 11 and a pressure plate 12 are mounted on the upper end of the frame 1. The sewing needle 11 is arranged vertically. The frame 1 is provided with a drive component for moving the sewing needle 11. The pressure plate 12 is slidably connected to the frame 1 vertically, and the pressure plate 12 has a clearance groove 121 through which the sewing needle 11 passes.

[0033] Reference Figure 1 and Figure 2 The lower end of the frame 1 is also provided with a placement box 2. The placement box 2 has a vertically opening material feeding groove 21. A guide frame 4 is provided in the material feeding groove 21. The frame 1 has a mounting groove 211 that communicates with the material feeding groove 21. The guide frame 4 is located in the mounting groove 211 and abuts against the inner wall of the mounting groove 211. The placement box 2 limits the guide frame 4 through the mounting groove 211 and the material feeding groove 21.

[0034] Reference Figure 2 and Figure 3The guide frame 4 contains two parallel arc-shaped plates 41, which are slidably connected to the guide frame 4 laterally. The guide frame 4 is equipped with an adjusting component 42, which includes a double-acting lead screw 421 and a sliding rod 422. The two arc-shaped plates 41 are located at opposite ends of the double-acting lead screw 421 and are threadedly connected to it. The sliding rod 422 is fixedly connected to the guide frame 4 laterally and slidably connects to both arc-shaped plates 41. Under the action of the guide frame 4 and the sliding rod 422, when the double-acting lead screw 421 is rotated, it causes the two arc-shaped plates 41 to move closer together or further apart.

[0035] Reference Figure 2 and Figure 3 Multiple buttons are placed sequentially between two curved plates 41. By adjusting the distance between the two curved plates 41, the plates work together to limit the buttons, reducing the probability of the buttons deviating between the plates. Each curved plate 41 has a rotating rod 43 passing through it along its length. The rotating rod 43 is rotatably connected to the curved plate 41, and a support plate 431 is vertically fixed to the lower end of the rotating rod 43. When a button is placed between the two curved plates 41, rotating the rotating rod 43 moves the support plate 431 to the position between the two curved plates 41, supporting the button. This facilitates the movement of all the buttons between the two curved plates 41 via the movable guide frame 4.

[0036] Reference Figure 2 and Figure 3 When the guide frame 4 is placed in the mounting slot 211, the rotating rod 43 is rotated, causing the rotating rod 43 to move the support plate 431 out from between the two arc-shaped plates 41. At this time, the button between the two arc-shaped plates 41 falls along the feed chute 21 under the action of gravity. A moving block 44 is slidably connected to the arc-shaped rod along its length, and a counterweight plate 441 is vertically hinged to the end of the moving block 44 away from the arc-shaped plate 41. When placing the button, the button is placed under the counterweight plate 441, so that the counterweight plate 441 presses the button tightly, reducing the probability of the button flipping over when moving along the arc-shaped plate 41.

[0037] Reference Figure 2 and Figure 4 The lower end of the placement box 2 has a discharge port 22 that communicates with the feed chute 21, and the discharge port 22 is directly opposite the sewing needle 11. Two feed rods 23 are slidably connected to the placement box 2 in a direction close to or away from the sewing needle 11. The two feed rods 23 are parallel to each other, and the discharge port 22 is located between the two feed rods 23. The feed rods 23 pass through the placement box 2. A drive cylinder 24 is installed on the side of the placement box away from the sewing needle 11. The output end of the drive cylinder 24 is connected to the two feed rods 23 to drive the two feed rods 23 to move.

[0038] Reference Figure 2 and Figure 4 The discharge port 22 is equipped with two sets of positioning plates 26, which are arranged vertically. Each set of positioning plates 26 contains two plates, located on opposite sides of the discharge port 22 along its width. The ends of the two positioning plates 26 that are furthest from each other are rotatably connected to the placement box 2 laterally. The discharge port 22 also contains corresponding stops 263, located at the end of the positioning plate 26 closest to the sewing needle 11. A second elastic element 262, a torsion spring, is provided between the positioning plate 26 and the placement box 2. The torsion spring exerts a force on the positioning plate 26, causing it to rotate towards the stop 263. When the positioning plate 26 contacts the stop 263, it is perpendicular to the feeding rod 23.

[0039] Reference Figure 2 and Figure 4 The placement box 2 also has a moving groove 28 along the length of the feeding rod 23. The moving groove 28 is connected to the discharge port 22 and is located below the feeding rod 23. A support block 281 is provided in the moving groove 28. The support block 281 is slidably connected to the placement box 2 along the length of the feeding rod 23, and the height of the upper end of the support block 281 is lower than the height of the lower end of the feeding chute 21. Among all the positioning plates 26, the lower positioning plate 26 is connected to the support block 281 by a connecting rod 282. One end of the connecting rod 282 is hinged to the positioning plate 26, and the other end is hinged to the support block 281. When the positioning plate 26 rotates away from the stop block 263, it drives the support block 281 to move along the moving groove 28 to below the feeding chute 21. When the positioning plate 26 abuts against the stop block 263, one end of the support block 281 is located outside the moving groove 28.

[0040] Reference Figure 2 and Figure 4 The placement box 2 is also equipped with a pusher, which includes a top block 31, an elastic element 32, and a pushing block 33 (see reference). Figure 1 The lower end of the placement box 2 has a receiving groove 271 that communicates with the feeding groove 21. The top plate is located in the receiving groove 271 and is slidably connected to the placement box 2 along the length of the feeding rod. The thickness of the top block 31 is no greater than the thickness of a single button. When the button moves to the bottom of the feeding groove 21 under the action of gravity, it is directly opposite the top block 31.

[0041] Reference Figure 1 and Figure 4The push block 33 is located on the side of the placement box 2 away from the sewing needle 11 and is fixedly connected to the feed rod 23. When the feed rod 23 moves, it drives the push block 33 to move closer to or away from the placement box 2. The placement box 2 has a through groove 272 that communicates with the receiving groove 271. The through groove 272 is directly opposite the top block 31. When a button needs to be placed, the feed rod 23 drives the push block 33 to move closer to the top block 31. When the push block 33 passes through the through groove 272 and comes into contact with the top block 31, it drives the top block 31 to move out of the receiving groove 271 and pushes the button at the lower end of the feed chute 21 closer to the positioning plate 26.

[0042] Reference Figure 1 and Figure 4 The elastic element 32 is a spring, with one end fixedly connected to the top block 31 and the other end fixedly connected to the placement box 2. When the top block 31 moves the button closer to the positioning plate 26, the elastic element 32 gradually deforms. When the feeding rod 23 moves the pushing block 33 to reset, the elastic element 32 moves the top block 31 back to its original position. At this time, the button in the feeding groove 21 moves again between the top block 31 and the positioning plate 26 under the action of gravity.

[0043] Reference Figure 4 The height of the connection between the discharge port 22 and the feed chute 21 is greater than the thickness of a single button but not greater than the thickness of two buttons. When the button is removed from the feed chute 21, it falls onto the support block 281 under the action of gravity, at which point the support block supports the button. Positioning slots 261 are provided at the positions where the positioning plates 26 are close to each other. Under the pushing force of the top block 31, one end of the button passes through the positioning slot 261.

[0044] Reference Figure 5 and Figure 6 The two feed rods 23 are close to the sewing needle 11 (reference) Figure 1 One end of the device is fixedly connected to a support plate 25. A clamping piece 251 is provided at the lower end of the support plate 25. The clamping piece 251 is slidably connected to the support plate 25 vertically. The support plate 25 moves to drive the clamping piece 251 to move. An elastic element 252 is provided between the clamping piece 251 and the support plate 25. The elastic element 252 is a spring. One end of the spring is fixedly connected to the clamping piece 251, and the other end is fixedly connected to the support plate 25. The elastic element 252 applies a force to the clamping piece 251 away from the support plate 25.

[0045] Reference Figure 5 and Figure 6The lower end of the feed rod 23 is provided with an abutment piece 231, which is perpendicular to the feed rod 23 and slidably connected to it along the width direction. A moving rod 232 is slidably connected to the feed rod 23 along its length. A hinge rod 233 is provided between the abutment piece 231 and the moving rod 232. One end of the hinge rod 233 is hinged to the moving rod 232, and the other end is hinged to the abutment piece 231. When the moving rod 232 moves away from the sewing needle 11 along the feed rod 23 (see reference...),... Figure 1 When the feed bar moves in the direction of the feed bar 23, the abutment plate 231 is driven to move away from the bearing plate 25 from between the two feed bars 23 via the hinge rod 233.

[0046] Reference Figure 5 and Figure 6 A baffle 234 is fixed to the end of the moving rod 232 away from the hinge rod 233. The baffle 234 is located in the placement box 2 (reference). Figure 1 ) Away from the sewing needle 11 (reference) Figure 1 On one side of the feed rod 232, the moving rod 232 moves, causing the baffle 234 to move. The feed rod 23 has a sliding groove 236 along its length, and the baffle 234 passes through the sliding groove 236 and extends away from the feed rod 23. An elastic element 235 is provided between the moving rod 232 and the feed rod 23. The elastic element 235 is a spring, one end of which is fixedly connected to the feed rod 23, and the other end is fixedly connected to the moving rod 232. In the natural state of the elastic element 235, the moving rod 232 is located close to the bearing plate 25, and at this time the abutment piece 231 is below the clamping piece 251.

[0047] Reference Figure 5 and Figure 6 When a button needs to be placed, the drive cylinder 24 moves the support plate 25 closer to the discharge port 22. When the clamping piece 251 and the abutting piece 231 enter the discharge port 22, they abut against the positioning plate 26. At this time, the button is aligned with the gap between the clamping piece 251 and the abutting piece 231. The feeding rod 23 continues to move, which in turn pushes the positioning plate 26 to rotate through the clamping piece 251 and the abutting piece 231. The rotation of the positioning plate 26 moves the support block 281. As the positioning plate 26 rotates, it pushes the button closer to the feed chute 21. When the positioning plate 26 rotates to the desired angle, it separates from the button. At this time, the button abuts against the side wall of the discharge port 22 near the feed chute 21, and the movement of the button is limited.

[0048] Reference Figure 4 and Figure 6The clamping plate 251 has a guide surface along its circumference. The guide surface moves from bottom to top, tilting away from the center of the clamping plate 251 as the feeding rod 23 continues to move, causing the button to enter between the clamping plate 251 and the abutment plate 231 along the guide surface. At this time, the elastic element 252 gradually compresses, causing the clamping plate 251 and the abutment plate 231 to cooperate in clamping the button. A circular groove 253 is formed at the lower end of the clamping plate 251, and multiple positioning rods 254 are arranged within the groove 253. The position and number of positioning rods 254 are determined according to the sewing hole of the button. After the button enters between the clamping plate 251 and the abutment plate 231, it is positioned within the circular hole. When the sewing hole of the button is aligned with the positioning rod 254, the positioning rod is inserted into the sewing hole under the action of the elastic element 252.

[0049] Reference Figure 2 and Figure 6 Elastic blocks 29 are fixed on both sides of the outlet 22 along its width direction. The elastic blocks 29 are arranged along the length direction of the feed rod 23, and the distance between the two elastic blocks 29 gradually decreases along the feed rod 23 towards the sewing needle 11. Manipulating the feed rod 23 moves the support plate 25 closer to the sewing needle 11, causing the clamping plate 251 and the abutment plate 231 to move the button. As the button moves, it passes between the two elastic blocks 29 and gradually contacts them. Each elastic block 29 has anti-slip grooves 291 along its length direction. When the button moves along the anti-slip grooves 291, it tends to rotate. When the positioning rod 254 is misaligned with the sewing hole, the button gradually rotates under the action of the elastic blocks 29. When the sewing hole and the positioning rod 254 are aligned, the positioning rod 254 enters the sewing hole.

[0050] Reference Figure 1 and Figure 6 When the clamping plate 251 and the abutting plate 231 move the button to below the pressing plate 12, the baffle 234 abuts against the placement box 2. At this time, the feeding rod 23 continues to move, causing the moving rod 232 to move relative to the feeding rod 23. When the moving rod 232 moves, it drives the abutting plate 231 to move out below the button through the connecting rod 282. Then, the clamping plate 251 pushes the button out under the action of the elastic element 252, so that the button falls on the outer skin of the toy. And through the action of the positioning rod 254, the button sewing hole is aligned with the sewing needle 11, thus completing the automatic feeding of the button, which helps to improve the convenience of sewing buttons.

[0051] The implementation principle of a sewing machine is as follows: Buttons are stored in a placement box 2. Under the limiting action of the feed chute 21, the buttons are neatly arranged vertically. When a button needs to be sewn, the feed rod 23 is moved, causing the push block 33 to drive the top block 31 to move. The top block 31 pushes the button below the feed chute 21 to above the support block 281. At this time, the positioning plate 26 limits the button. The feed rod is moved in the opposite direction, causing the support plate 25 to drive the clamping piece 251 into the discharge port 22, and pushing the positioning plate 26 away from the stop block 263. At this time, under the limiting action of the side wall of the discharge port 22, the button enters between the clamping piece 251 and the abutment piece 231 along the guide surface. The feeding rod 23 is manipulated to move the bearing plate 25 closer to the sewing needle 11, thereby moving the button to the bottom of the pressing plate 12. During the movement of the feeding rod 23, the baffle 234 is driven to abut against the placement box 2, causing the baffle 234 to drive the moving rod 232 to move along the sliding groove 236. The moving rod 232 drives the abutting piece 231 to avoid the button through the connecting rod 282, so that the clamping piece 251 pushes the button above the toy's outer skin under the action of the elastic element 252, thereby completing the button feeding and improving the convenience of sewing buttons.

[0052] This application also discloses an improved sewing machine table.

[0053] Reference Figure 5 An improved sewing machine table includes a table 5 and a support block 52. The table 5 is connected to the end of the machine frame 1. A slot 51 is provided on the upper end of the table 5. The support block 52 is located in the slot 51 and fits against the inner wall of the slot 51. A limiting groove 53 is provided on the upper end of the support block 52. The limiting groove 53 is located directly below the sewing needle 11 and is set according to the button. Different support blocks 52 have different sizes of limiting grooves 53. When sewing a button, the toy skin is placed above the support block 52 and the table 5. When the button is placed below the sewing needle 11 and the button is pressed by the pressing plate 12, the button pulls the skin into the limiting groove 53. At this time, the support plate limits the button through the limiting groove 53, thereby reducing the probability of the button deviating during sewing.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
