Description

Technical Field

[0001] The invention relates to the field of embroidery machines, in particular to a sheet feeding mechanism of a double sequin device of an embroidery machine. Background Art

[0002] As an industrial sewing equipment, embroidery machines have been widely used. Sequin embroidery is a common embroidery method. Sequin embroidery is to sew circular single sequins onto the fabric to serve as embellishment. Before the single sequins are sewn onto the fabric, some pieces are connected together to form a sequin chain, which is convenient for the transportation of sequins.

[0003] The feeding mechanism is an auxiliary feeding device to improve the working efficiency of the embroidery machine. It can automatically feed the sequin chain connected in strips to the embroidery needle, and then cut the sequins fed to the embroidery needle, so that they are separated from the sequin chain and fall on the fabric, so that the embroidery machine can automatically sew them on the fabric surface. The sequin feeding mechanism automatically feeds the sequin strips according to the set frequency and displacement. The double sequin feeding mechanism can feed two sequin chains at the same time, so that two sequin chains of different sizes and center distances can be fed at the same time, and the center of the first sequin of the two sequin chains can be moved to the same point, so that the embroidery needle can pass through the two sequins at the same time and sew them. It is usually required that the large sequin be sewn under the small sequin.

[0004] The existing double sequin feeding mechanism is usually provided with two sets of driving motors, which respectively control two sets of transmission mechanisms, and each transmission mechanism can drive a paddle mechanism to work; each paddle mechanism performs its own function to transport sequins of different specifications, so as to achieve the purpose of simultaneously outputting a variety of sequins of different specifications on the same computer embroidery machine. Although this method can realize the simultaneous transportation of two sequin chains, each transportation mechanism needs to be equipped with a set of independent driving motors, resulting in a large overall volume of the double sequin feeding mechanism. When the embroidery needle sews the sequins and the fabric subsequently, the thickness of the double sequin feeding mechanism will be increased due to the multiple sets of driving motors. Therefore, during the subsequent sewing, the embroidery needle is easy to collide with the double sequin feeding mechanism, causing damage to the embroidery needle, affecting the sewing efficiency of the fabric. At the same time, the two sets of driving motors will also increase the overall weight of the mechanism, increasing the production cost. In view of this problem, a feeding mechanism of a double sequin device of an embroidery machine is now provided.

[0044] 2. The present invention provides a double sequin device feeding mechanism for an embroidery machine. By setting a first moving groove and a sliding rod, when the first sliding rod drives the sliding rod to move horizontally, it can drive the second swinging rod to rotate. Since the second swinging rod and the rear swinging arm are fixedly connected, when the upper end of the second swinging rod rotates, it can drive the rear swinging arm to rotate, so that the end of the rear swinging arm close to the sequin can be tilted up, so as to realize the movement of the sequin inside the lower guide groove. By providing a second moving groove on the surface of the front swinging arm, due to the setting of the horizontal groove part, the movement trajectory of the front swinging arm is firstly horizontal movement, and then due to the setting of the arc groove part, the front swinging arm can realize The rear swing arm is rotated so that the end of the front swing arm close to the sequin can be tilted up, so as to realize the toggling of the sequin inside the upper guide groove. That is, when the rear swing arm toggles the sequin, the front swing arm first drives the sequin to move horizontally, and then applies a toggling action to the sequin. When the front swing arm drives the small sequin located inside the upper guide groove to move in a straight line, a buffer time can be provided for the large sequin located inside the lower guide groove. When the large sequin is pushed out, the small sequin can be pushed out just in time, so that the axis of the small sequin can be consistent with the axis of the large sequin, so that the embroidery needle can pass through the two sequins at the same time, so that the two sequins can be sewn at the same time, and the feeding accuracy is improved.

[0045] 3. The present invention provides a double sequin device feeding mechanism for an embroidery machine. By setting a cutting assembly and two sets of positioning plates staggered up and down and left and right, when the moving part is working, the two sets of positioning plates can be driven to move left and right, so that two sets of sequins of different sizes can be cut at the same time, so that the small sequins can just fall on the top of the large sequins, so that the small sequins and the large sequins overlap, which is convenient for the subsequent sewing of the large and small sequins;

[0046] 4. The present invention provides a film feeding mechanism for a double sequin device of an embroidery machine.

DETAILED DESCRIPTION

[0058] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0059] The present invention provides the following preferred embodiments:

[0060] Embodiment 1, as Figure 1-Figure 10 As shown, a double sequin device feeding mechanism of an embroidery machine includes a mounting plate 11, a lower base plate 12 and an upper base plate 13 are mounted on one side of the mounting plate 11, the upper base plate 13 is located above the lower base plate 12, and a lower guide groove 14 and an upper guide groove 15 for conveying a sequin chain are respectively opened in the middle of the upper end surfaces of the lower base plate 12 and the upper base plate 13. Specifically, the upper guide groove 15 is located directly above the lower guide groove 14, ensuring that the small sequins in the upper guide groove 15 can be located above the large sequins in the lower guide groove 14, so that the small sequins after output can be located above the large sequins, which is convenient for the embroidery needle to pass through two sequins at the same time and sew;

[0061] It also includes a first driving assembly, a first toggle assembly, a second driving assembly, a second toggle assembly, and a cutting assembly;

[0062] The first toggle assembly is located above the lower guide groove 14, and the first toggle assembly is used to toggle the sequin chain located inside the lower guide groove 14. The first driving assembly is located on the left side of the first toggle assembly, and the first driving assembly is used to control the operation of the first toggle assembly. By setting the first driving assembly and the first toggle assembly, the first driving assembly can be used to control the operation of the first toggle assembly, so that the first toggle assembly can realize the toggle of the sequin chain inside the lower guide groove 14, so that the first sequin in the sequin chain inside the lower guide groove 14 can be moved out of the lower guide groove 14, which is convenient for subsequent cutting of the sequin;

[0063] The second toggle assembly is located above the upper guide groove 15, and the second toggle assembly is used to toggle the sequin chain located inside the upper guide groove 15. The second driving assembly is located on a side of the second toggle assembly close to the first toggle assembly, and the second driving assembly is used to control the operation of the second toggle assembly. Through the second driving assembly and the second toggle assembly, the second driving assembly can control the operation of the second toggle assembly, so that the second toggle assembly can realize the toggle of the sequin chain inside the upper guide groove 15, so that the first sequin in the sequin chain inside the upper guide groove 15 can be moved out of the upper guide groove 15, which is convenient for the subsequent cutting of the sequin;

[0064] When the first driving component is working, the second driving component can be driven to work synchronously, so that the first toggle component can work synchronously with the second toggle component, so that the double sequin feeding mechanism can use the mobile electric push rod 21 to drive two independent toggle components to work at the same time. Compared with the existing double sequin feeding mechanism, the present invention greatly reduces the volume of the double sequin feeding mechanism, effectively avoiding the possibility of collision between the embroidery needle and the feeding mechanism when the embroidery machine is working, and at the same time reduces the overall weight of the mechanism and reduces the production cost.

[0065] The cutting assembly is located on a side of the mounting plate 11 away from the lower base plate 12, and the cutting assembly is used to cut off the first sequin on the sequin chain;

[0066] By setting a cutting assembly, two groups of positioning plates 62 are staggered vertically and horizontally. When the moving part is working, the two groups of positioning plates 62 can be driven to move, so that two groups of sequins of different sizes can be cut at the same time, so that the small sequins can just fall on the top of the large sequins, and the small sequins and the large sequins can overlap, which is convenient for the subsequent sewing of the large and small sequins.

[0067] like Figure 4 As shown, the first toggle assembly includes a rear swing arm 16, a second swing rod 32, a slide rod 30 and a pusher;

[0068] The rear swing arm 16 is located above the lower guide slot 14, and the bottom end of the rear swing arm 16 extends into the interior of the lower guide slot 14. It should be noted here that in the initial state, the rear positioning block 18 at the bottom end of the rear swing arm 16 does not contact the sequin. In the process of the rear swing arm 16 driving the rear positioning block 18 to rotate, the rear positioning block 18 can extend into the center hole of the sequin. As the rear swing arm 16 continues to rotate, the rear positioning block 18 can move the sequin until the rear positioning block 18 is separated from the sequin. The other end of the rear swing arm 16 is fixedly connected to the second swing rod 32, and the surface of the second swing rod 32 is rotatably connected to a second fixing rod 66 through a bearing. The other end of the second fixing rod 66 is fixedly connected to the mounting plate 11. The second fixing rod 66 is set so that the second swing rod 32 can rotate around the axis of the second fixing rod 66. At the same time, the setting of the second fixing rod 66 can also provide support for the installation of the second swing rod 32.

[0069] A first moving groove 31 is provided on the surface of the second swinging rod 32, and the first moving groove 31 is located at the end of the second fixed rod 66 away from the rear swinging arm 16. The sliding rod 30 is located inside the first moving groove 31, and the sliding rod 30 is slidably connected with the first moving groove 31. A fixed seat 29 is provided on one side of the second swinging rod 32, and the sliding rod 30 is located in the middle of the fixed seat 29, and the two ends of the sliding rod 30 are rotatably connected with the fixed seat 29. When the fixed seat 29 moves horizontally, the fixed seat 29 can drive the sliding rod 30 to move horizontally. Since the sliding rod 30 can slide inside the first moving groove 31, the sliding rod 30 can drive the second swinging rod 32 to rotate when it moves.

[0070] The pushing member is located between the first driving assembly and the fixing seat 29, and is used to push the fixing seat 29 to move horizontally. Two ends of the pushing member are in contact with the first driving assembly and the fixing seat 29 respectively.

[0071] The pusher can be used to push the fixing seat 29 to move horizontally. When the fixing seat 29 moves to the side away from the second swing rod 32, the slide bar 30 can slide inside the first moving groove 31 and drive the second swing rod 32 to rotate around the axis of the second fixing rod 66. At this time, the second swing rod 32 rotates counterclockwise, and the second swing rod 32 can drive the rear swing arm 16 to rotate counterclockwise. During the rotation of the rear swing arm 16, the rear positioning block 18 under the rear swing arm 16 can extend into the center hole of the sequin and can move the sequin, so that the first sequin in the sequin chain can move out of the lower guide groove 14.

[0072] When the pushing member pushes the fixing seat 29 to move toward the side close to the second swing rod 32, the sliding rod 30 also slides inside the first moving groove 31. At this time, the second swing rod 32 can rotate clockwise around the axis of the second fixing rod 66. At this time, the second swing rod 32 can drive the rear swing arm 16 to rotate clockwise, so that the rear swing arm 16 can be reset. In the process of resetting the rear swing arm 16, since one side of the rear positioning block 18 is arranged in an inclined surface, that is, when the rear positioning block 18 is reset, the rear positioning block 18 will not move the sequins backward using the setting of the inclined surface, and will not cause displacement of the sequins.

[0073] like Figure 4 As shown, the pusher comprises a first sliding sleeve 25, a first sliding rod 26, a push plate 27 and a pressing spring 28;

[0074] The first slide bar 26 is located at one side of the fixing seat 29, and one end of the first slide bar 26 is fixedly connected to the fixing seat 29. The first slide sleeve 25 is sleeved on the surface of the first slide bar 26. One side of the first slide sleeve 25 is fixedly connected to the mounting plate 11 through the first mounting bracket 33. The first slide bar 26 slides inside the first slide sleeve 25. The first slide sleeve 25 can limit the first slide bar 26 so that the first slide bar 26 can only move along the axis of the first slide sleeve 25.

[0075] The push plate 27 is fixed to one end of the first slide bar 26 away from the fixed seat 29, the pressing spring 28 is sleeved on the surface of the first slide bar 26, and the two ends of the pressing spring 28 are fixedly connected to the push plate 27 and the first sliding sleeve 25 respectively;

[0076] The arrangement of the pressing spring 28 enables the push plate 27 to always press against the first driving assembly.

[0077] like Figure 4 As shown, the first driving assembly includes an electric push rod 21, a first swing rod 22 and a push block 24;

[0078] The electric push rod 21 is located at one side of the mounting plate 11. Specifically, the electric push rod 21 is initially in an extended state. A mounting rod 20 is fixed to the surface of the mounting plate 11. The fixed end of the electric push rod 21 is hinged to the mounting rod 20. The output end of the electric push rod 21 is hinged to one end of the first swing rod 22. The push block 24 is fixed to one end of the first swing rod 22 away from the electric push rod 21. The push block 24 abuts against the surface of the push plate 27.

[0079] The middle part of the first swing rod 22 is rotatably connected to a first fixing rod 23 via a bearing, and one end of the first fixing rod 23 is fixedly connected to the mounting plate 11;

[0080] When in use, the electric push rod 21 is retracted. At this time, the electric push rod 21 can drive the first swing rod 22 to rotate clockwise around the axis of the first fixed rod 23. When the first fixed rod 23 rotates, it can drive the push block 24 to move to the side away from the first slide rod 26. At this time, under the action of the tightening spring 28, the push plate 27 can be pushed to move to the side close to the push block 24. When the push plate 27 moves, it can drive the first slide rod 26 to move, thereby driving the fixed seat 29 to move to the side away from the second swing rod 32. At this time, the rear swing arm 16 can rotate counterclockwise to pull out the sequins.

[0081] When the electric push rod 21 is in the extended state again, the electric push rod 21 can drive the first swing rod 22 to rotate counterclockwise around the axis of the first fixed rod 23. When the first fixed rod 23 rotates, it can drive the push block 24 to move toward the side close to the first slide rod 26. At this time, the push block 24 can push the push plate 27 to move, and the push plate 27 pushes the first slide rod 26 to slide inside the first sliding sleeve 25. The first slide rod 26 drives the fixed seat 29 to move toward the side close to the second swing rod 32. At this time, the second swing rod 32 can drive the rear swing arm 16 to rotate clockwise, so that the rear swing arm 16 can be reset, which is convenient for the rear swing arm 16 to perform the next dialing work.

[0082] like Figure 5 As shown, the second toggle assembly includes a front swing arm 17, a hinge rod 46, a second slide rod 44 and a guide portion;

[0083] The front swing arm 17 is located above the upper guide groove 15, and one end of the front swing arm 17 extends into the interior of the upper guide groove 15. In the initial state, the front positioning block 19 at the bottom end of the front swing arm 17 does not contact the sequins. When the front swing arm 17 drives the front positioning block 19 to rotate, the front positioning block 19 can extend into the center hole of the sequins. As the front swing arm 17 continues to rotate, the front positioning block 19 can move the sequins until the front positioning block 19 is separated from the sequins. The other end of the front swing arm 17 is hinged to one end of the hinged rod 46, and the other end of the hinged rod 46 is hinged to one end of the second sliding rod 44.

[0084] The surface of the second sliding rod 44 is sleeved with a second sliding sleeve 43, and the second sliding rod 44 slides inside the second sliding sleeve 43. The second sliding sleeve 43 can limit the second sliding rod 44, so that the second sliding rod 44 can only move along a certain direction. A second mounting bracket 45 is fixed to the side of the second sliding sleeve 43 close to the mounting plate 11, and the other end of the second mounting bracket 45 is fixedly connected to the mounting plate 11. The second mounting bracket 45 is used to install and fix the second sliding sleeve 43, thereby increasing the stability of the second sliding sleeve 43.

[0085] The second driving assembly is located at one end of the second sliding rod 44 away from the hinge rod 46, and the second driving assembly is used to drive the second sliding rod 44 to move horizontally;

[0086] The guide portion is located on the surface of the front swing arm 17, and the guide portion is used to guide the front swing arm 17 when it moves.

[0087] like Figure 5 As shown, the guide portion includes a second moving groove 47 and a positioning rod 48;

[0088] The second movable groove 47 is formed on the surface of the front swing arm 17. The second movable groove 47 includes a horizontal groove portion 64 and an arc-shaped groove portion 65 located on the left side of the horizontal groove portion 64. The horizontal groove portion 64 is horizontal, and the arc-shaped groove portion 65 is arc-shaped.

[0089] The positioning rod 48 is located inside the second movable groove 47, and the positioning rod 48 is slidably connected to the second movable groove 47. The end of the positioning rod 48 close to the mounting plate 11 is fixedly connected to the mounting plate 11. Specifically, in the initial state, the positioning rod 48 is located inside the horizontal groove portion 64 and away from the end of the arc-shaped groove portion 65.

[0090] During operation, the second driving assembly can drive the second slide bar 44 to move horizontally inside the second mounting frame 45. When the second slide bar 44 moves toward the side close to the front swing arm 17, the sliding connection between the horizontal groove portion 64 and the positioning rod 48 can be used to limit the front swing arm 17, so that when the second slide bar 44 moves, the front swing arm 17 can be driven to move horizontally through the hinge rod 46. At this time, the front positioning block 19 under the front swing arm 17 moves horizontally. When the front positioning block 19 moves horizontally, it does not contact the sequins. When the second slide bar 44 continues to move horizontally , the sliding connection between the arc-shaped groove portion 65 and the positioning rod 48 can be used to limit the front swing arm 17, so that the front swing arm 17 can rotate, and the front positioning block 19 at the bottom of the front swing arm 17 can rotate counterclockwise. In the process of the front swing arm 17 driving the front positioning block 19 to rotate, the front positioning block 19 first does not contact the sequins. In the process of the front positioning block 19 continuing to rotate, the front positioning block 19 can extend into the center hole of the sequins. As the front swing arm 17 continues to rotate, the front positioning block 19 can move the sequins until the front positioning block 19 is separated from the sequins.

[0091] That is, due to the setting of the horizontal groove portion 64, the movement trajectory of the front swing arm 17 is first horizontal movement, and then due to the setting of the arc groove portion 65, the front swing arm 17 can be rotated, so that the end of the front swing arm 17 close to the sequin can be tilted, so as to realize the movement of the sequin inside the upper guide groove 15, that is, when the rear swing arm 16 moves the sequin, the front swing arm 17 first drives the sequin to move horizontally, and then exerts a moving action on the sequin;

[0092] Similarly, when the second slide bar 44 moves to the side away from the front swing arm 17, during the movement of the second slide bar 44, the front swing arm 17 first rotates and then moves in a straight line, so that the front swing arm 17 can be reset, which is convenient for the front swing arm 17 to perform the next shifting work. During the reset of the front swing arm 17, since one side of the front positioning block 19 is arranged in an inclined surface, that is, when the front positioning block 19 is reset, the front positioning block 19 will not shift the sequins backward by utilizing the setting of the inclined surface, and will not cause displacement of the sequins.

[0093] It should be noted here that since the diameter of the sequin inside the lower guide groove 14 needs to be larger than the diameter of the sequin inside the upper guide groove 15, that is, the rear swing arm 16 above the lower guide groove 14 needs to first apply a tossing action to the large sequin to ensure that the axes of the large and small sequins can coincide after being pushed out, that is, before the front swing arm 17 tosses the small sequin, it is necessary to provide a buffer time for the tossing of the rear swing arm 16, and when the front swing arm 17 first moves horizontally, it can just increase the buffer time for the tossing of the rear swing arm 16, that is, the front swing arm 17 first drives the sequin to move horizontally, and then applies a tossing action to the sequin. When the front swing arm 17 drives the small sequin located in the upper guide groove 15 to move in a straight line, it can provide a buffer time for the large sequin located in the lower guide groove 14. When the large sequin is pushed out, the small sequin can be just pushed out, so that the axis of the small sequin can be consistent with the axis of the large sequin, which is convenient for the embroidery needle to pass through the two sequins at the same time, and it is convenient to sew the two sequins at the same time, thereby improving the feeding accuracy.

[0094] like Figure 5 As shown, the second driving assembly includes a support rod 34, a third swing rod 36, a return spring 39 and a pulley 41;

[0095] The third swing rod 36 is located at one side of the second slide rod 44, and the bottom end of the third swing rod 36 is rotatably connected to the third fixing rod 37 through a bearing, and one end of the third fixing rod 37 close to the mounting plate 11 is fixedly connected to the mounting plate 11;

[0096] A support rod 34 is fixed to the side of the third swing rod 36 close to the rear swing arm 16, and a toggle block 35 is fixed to the side of the support rod 34 close to the rear swing arm 16. The side of the toggle block 35 close to the rear swing arm 16 abuts against the surface of the rear swing arm 16, and the side of the toggle block 35 close to the rear swing arm 16 is an inclined surface matched with the surface of the rear swing arm 16. When the rear swing arm 16 rotates counterclockwise (that is, when the large sequin is toggled), a driving force can be applied to the toggle block 35, and at this time, the toggle block 35 can drive the third swing rod 36 to rotate around the third swing arm 16 through the support rod 34. The axis of the fixing rod 37 rotates clockwise, and a return spring 39 is fixed on the surface of the third swing rod 36 above the support rod 34. A fixing plate 38 is fixed to the other end of the return spring 39. The fixing plate 38 is fixed to the surface of the mounting plate 11. The setting of the return spring 39 can drive the third swing rod 36 to reset, that is, when the rear swing arm 16 rotates clockwise (that is, when the rear swing arm 16 is reset), the third swing rod 36 can be reset under the action of the return spring 39, and at this time, the toggle block 35 can contact the surface of the rear swing arm 16 again;

[0097] A rotating seat 42 is fixed to one end of the second slide bar 44 close to the third swing bar 36, and a pulley 41 is rotatably connected to the middle of the rotating seat 42. A sliding groove 40 matching with the pulley 41 is provided on one side of the third swing bar 36 close to the pulley 41, and the pulley 41 slides inside the sliding groove 40;

[0098] When the rear swing arm 16 rotates counterclockwise (i.e., when the large sequin is tossed), it can synchronously drive the third swing rod 36 to rotate clockwise around the axis of the third fixed rod 37. At this time, since the pulley 41 can roll inside the slide groove 40, the third swing rod 36 can push the second slide rod 44 to move to the side close to the front swing arm 17, so that the front swing arm 17 can first move horizontally (at this time, the rear swing arm 16 has begun to toggle the large sequin), and then the front swing arm 17 rotates counterclockwise. In the process of the front swing arm 17 driving the front positioning block 19 to rotate, the front positioning block 19 does not contact the sequin at first. In the process of the current positioning block 19 continuing to rotate, the front positioning block 19 can extend into the center hole of the sequin. As the front swing arm 17 continues to rotate, the front positioning block 19 can toggle the sequin until the front positioning block 19 is separated from the sequin.

[0099] When the rear swing arm 16 rotates clockwise (i.e., when the rear swing arm 16 is reset), the third swing rod 36 can be reset under the action of the reset spring 39. Due to the restrictions of the pulley 41 and the slide groove 40, the second slide rod 44 can be pulled to move to the side away from the front swing arm 17. During the movement of the second slide rod 44, the front swing arm 17 first rotates and then moves in a straight line, so that the front swing arm 17 can be reset, which is convenient for the front swing arm 17 to perform the next shifting work.

[0100] like Figure 6-Figure 7 As shown, the cutting assembly includes a moving plate 55, a cutting knife 61, a motor mounting seat 51 and a moving part;

[0101] The motor mounting seat 51 is located at a side of the mounting plate 11 away from the lower base plate 12, and the motor mounting seat 51 is fixedly connected to the mounting plate 11. A T-slot 53 is provided at the end of the motor mounting seat 51, and a T-slot slider 54 is slidably connected inside the T-slot 53. The movable plate 55 is located at one side of the T-slot slider 54 and is fixedly connected to the T-slot slider 54. The T-slot 53 and the T-slot slider 54 can be used to limit the movable plate 55 when it moves, so that the movable plate 55 can only move in a certain direction, and at the same time, the stability of the movable plate 55 when it moves is increased, the stability of the cutting knife 61 when it moves is increased, and the cutting accuracy of the cutting knife 61 is increased;

[0102] The cutting knives 61 are provided in two groups, and the two groups of cutting knives 61 are staggered up and down and left and right. The two groups of cutting knives 61 are used to cut the sequins, and the cutting knives 61 are fixedly connected to the moving plate 55;

[0103] The moving part is located above the motor mounting seat 51, and the moving part is used to drive the moving plate 55 to move;

[0104] During operation, the moving part can drive the moving plate 55 to move, and the moving plate 55 can drive the two sets of cutting knives 61 to move, so that the cutting knives 61 can move left and right to cut off the large and small sequins.

[0105] like Figure 6-Figure 7 As shown, the moving part includes a motor 52 fixed above the motor mounting seat 51, a rotating disk 59 is fixed at the output end of the motor 52, and a toggle rod 58 is fixed at the surface edge of the rotating disk 59;

[0106] A connecting rod 56 is fixed to the top of the moving plate 55, a moving frame 57 is fixed to the other end of the connecting rod 56, the toggle rod 58 is located inside the moving frame 57, and the toggle rod 58 is slidably connected to the moving frame 57;

[0107] When the motor 52 is working, it can drive the turntable 59 to rotate. When the turntable 59 rotates, it can drive the toggle rod 58 to rotate. Due to the sliding connection between the T-slot 53 and the T-sliding block 54, the moving plate 55 can be restricted, so that the moving frame 57 can be restricted. That is, when the toggle rod 58 rotates, it can drive the moving frame 57 to move left and right. When the moving frame 57 moves, it can drive the moving plate 55 to move through the connecting rod 56, so that the cutting knife 61 can be driven to move.

[0108] Specifically, when the toggle lever 58 is rotated to the upper and lower sides, the movable frame 57 can move to the rightmost side to provide space for large and small sequins, facilitate the removal of large and small sequins, and play a role of giving way. When the toggle lever 58 is rotated to the left and right sides, the movable frame 57 can move to the leftmost side. At this time, the cutting knife 61 can cut off the large and small sequins.

[0109] like Figure 8-Figure 10 As shown, a rear positioning block 18 is fixed to the bottom end of the rear swing arm 16, and a front positioning block 19 is fixed to the bottom end of the front swing arm 17. By respectively arranging the rear positioning block 18 and the front positioning block 19 below the rear swing arm 16 and the front swing arm 17, when the sequins are tossed, the rear positioning block 18 and the front positioning block 19 are respectively extended into the center holes of the large sequins and the small sequins, so as to facilitate the toggling of the sequins and avoid the rear swing arm 16 or the front swing arm 17 and the surface of the sequins from slipping, thereby ensuring that each film feeding process is effective, thereby improving work efficiency, and the side of the rear positioning block 18 and the front positioning block 19 away from the end of the rear swing arm 16 and the front swing arm 17 is arranged in an inclined surface, that is, when the rear positioning block 18 and the front positioning block 19 are reset, the arrangement of the inclined surface is utilized to ensure that the rear positioning block 18 and the front positioning block 19 will not toggle the sequins to move backward.

[0110] The specific working process of the present invention is as follows:

[0111] When working, firstly, the large and small sequin chains are placed inside the lower guide groove 14 and the upper guide groove 15 respectively. When the electric push rod 21 works, it can drive the first swing rod 22 to rotate clockwise around the axis of the first fixed rod 23. When the first fixed rod 23 rotates, it can drive the push block 24 to move to the side away from the first slide bar 26. At this time, under the action of the tightening spring 28, the push plate 27 can be pushed to move to the side close to the push block 24. When the push plate 27 moves, it can drive the first slide bar 26 to move, thereby driving the fixing seat 29 to move to the side away from the second swing rod 32. At this time, the rear swing arm 16 can rotate counterclockwise. During the rotation of the rear swing arm 16, the rear positioning block 18 under the rear swing arm 16 can extend into the center hole of the sequin and can move the sequin, so that the first sequin in the sequin chain can move out of the lower guide groove 14.

[0112] When the rear swing arm 16 rotates counterclockwise (i.e., when the large sequin is tossed), it can synchronously drive the third swing rod 36 to rotate clockwise around the axis of the third fixed rod 37. At this time, since the pulley 41 can roll inside the slide groove 40, the third swing rod 36 can push the second slide rod 44 to move to the side close to the front swing arm 17, so that the front swing arm 17 can first move horizontally (at this time, the rear swing arm 16 has begun to toggle the large sequin), and then the front swing arm 17 rotates counterclockwise. In the process of the front swing arm 17 driving the front positioning block 19 to rotate, the front positioning block 19 does not contact the sequin at first. In the process of the front positioning block 19 continuing to rotate, the front positioning block 19 can extend into the center hole of the sequin. As the front swing arm 17 continues to rotate, the front positioning block 19 can toggle the sequin until the front positioning block 19 is separated from the sequin, so that the first sequin in the sequin chain can move out of the upper guide groove 15.

[0113] The motor 52 is controlled to work. When the motor 52 is working, the turntable 59 can be driven to rotate. When the turntable 59 rotates, the toggle rod 58 can be driven to rotate. Due to the sliding connection between the T-slot 53 and the T-slider 54, the mobile plate 55 can be restricted, thereby limiting the mobile frame 57. That is, when the toggle rod 58 is rotating, the mobile frame 57 can be driven to move left and right. When the mobile frame 57 moves, the mobile plate 55 can be driven to move through the connecting rod 56, thereby driving the cutting knife 61 to move, thereby cutting off large and small sequins, which is convenient for embroidery to sew large and small sequins;

[0114] When the electric push rod 21 is in the extended state again, the electric push rod 21 can drive the first swing rod 22 to rotate counterclockwise around the axis of the first fixed rod 23. When the first fixed rod 23 rotates, it can drive the push block 24 to move to the side close to the first slide rod 26. At this time, the push block 24 can push the push plate 27 to move, and the push plate 27 pushes the first slide rod 26 to slide inside the first sliding sleeve 25. The first slide rod 26 drives the fixed seat 29 to move to the side close to the second swing rod 32. At this time, the second swing rod 32 can drive the rear swing arm 16 to rotate clockwise, so that the rear swing arm 16 can be reset, which is convenient for the rear swing arm 16 to perform the next dialing work. In the process of resetting the rear swing arm 16, one side of the rear positioning block 18 is arranged in an inclined surface, that is, when the rear positioning block 18 is reset, the rear positioning block 18 will not move the sequin backward by using the setting of the inclined surface, and will not cause the displacement of the sequin;

[0115] When the rear swing arm 16 rotates clockwise (i.e., when the rear swing arm 16 is reset), the third swing rod 36 can be reset under the action of the reset spring 39. Due to the restrictions of the pulley 41 and the slide groove 40, the second slide rod 44 can be pulled to move to the side away from the front swing arm 17. During the movement of the second slide rod 44, the front swing arm 17 first rotates and then moves in a straight line, so that the front swing arm 17 can be reset, which is convenient for the front swing arm 17 to perform the next shifting work.

[0116] Embodiment 2: Figure 7 As shown, in order to improve the cutting accuracy of the positioning plate 62, the surface of the movable plate 55 is provided with an adjustment component for adjusting the position of the positioning plate 62, and the adjustment component includes a plurality of threaded holes opened on the surface of the movable plate 55, and the plurality of threaded holes are arranged equidistantly above and below the adjustment slot 60, and the surface of the positioning plate 62 is provided with a plurality of through holes that penetrate the positioning plate 62 and correspond to the threaded holes, and the inside of the through holes is provided with bolts 63; the bolts 63 pass through the through holes and are threadedly connected with the threaded holes;

[0117] When the position of the cutting knife 61 needs to be adjusted, the cutting knife 61 is moved so that the cutting knife 61 can drive the internal movement of the adjustment slot 60. At the same time, the movement of the cutting knife 61 can drive the positioning plate 62 to move, so that the perforations on the positioning plate 62 can correspond to the threaded holes at different positions, and the bolts 63 are used to achieve a fixed connection between the positioning plate 62 and the movable plate 55, so that the position of the positioning plate 62 can be adjusted, thereby adjusting the position of the cutting knife 61. The invention is suitable for cutting sequins of different diameters, has a wide range of applications, can effectively improve the cutting accuracy of the cutting knife 61, and meets the use requirements.

[0118] Embodiment 3: Figure 1-Figure 5As shown, in order to facilitate the sequin chain to be transported more stably in the lower guide groove 14 or the upper guide groove 15, the lower guide groove 14 and the upper guide groove 15 are respectively provided with a lower guide wheel 49 and an upper guide wheel 50 for positioning the sequin chain;

[0119] The lower guide wheels 49 are provided in multiple groups, and the multiple groups of lower guide wheels 49 are equidistantly arranged inside the lower guide groove 14, and the two ends of the lower guide wheels 49 are hinged to the inner wall of the lower guide groove 14; the upper guide wheels 50 are provided in multiple groups, and the multiple groups of upper guide wheels 50 are equidistantly arranged inside the upper guide groove 15, and the two ends of the upper guide wheels 50 are hinged to the inner wall of the upper guide groove 15;

[0120] By setting the lower guide wheel 49 and the upper guide wheel 50, when the sequins are transported inside the lower guide groove 14 or the upper guide groove 15, the lower guide wheel 49 and the upper guide wheel 50 can be used to limit the sequin chain, thereby preventing the sequin chain from bending during the transportation inside the lower guide groove 14 and the upper guide groove 15, and facilitating the use of the rear swing arm 16 and the front swing arm 17 to move the sequin chain, thereby improving the stability during feeding and also improving the feeding accuracy of the sequins.

[0121] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
