Description

Technical Field

[0001] The present application relates to the field of spinning technology, and in particular to a yarn tube color separation, finishing and recycling system. Background Art

[0002] The bobbins produced by the automatic winding machines used by textile companies are often scattered in the storage area. The bobbins are tapered tubes with one end larger than the other, and often come in a variety of colors. When these bobbins are reused, they need to be sorted and collected according to their colors for next use. Large bobbins with excess yarn also need to be color-separated. Currently, some small textile companies usually rely on manual sorting, which is inefficient, labor-intensive, and has high production costs. In order to save labor costs, more and more automated equipment is currently available on the market that can automatically separate the colors of the bobbins in the storage area so that the recovered bobbins can be reused.

[0003] For example, Chinese patent application number 201610792180.0 discloses a spun yarn tube color recognition and conveying device including a support frame, a transverse conveying mechanism, an industrial visual recognition system and multiple color separation actuators. By adopting a striking mechanism during color separation recognition, the processing speed is greatly improved compared with the cylinder structure, and the structure is simple, and the processing speed is high and effective; the industrial visual system uses a camera to identify the color of the yarn tube, which improves efficiency and recognition accuracy compared to the original method of taking pictures with a camera, and saves time; by setting up multiple color separation actuators, that is, through modular management of the color separation actuators, yarn tubes of multiple colors can be identified.

[0004] For example, Chinese patent application number 201710115589.3 discloses a bobbin limiting mechanism, in which the diameters of the two ends of the bobbin are inconsistent, with a large end and a small end respectively. The limiting mechanism includes a bracket, a hopper is provided above the bracket, a feed port is provided at the upper end of the hopper, an inclined surface for the bobbin to slide down is provided in the feed port, a bobbin turning rod is provided between the inclined surface and the inner wall of the hopper opposite to the inclined surface, a bobbin channel for allowing the bobbin to fall vertically is provided below the hopper, and a discharging mechanism is connected below the bobbin channel. The present invention can enable the bobbin to fall neatly into the bobbin basket in the direction of consistency between the large and small ends, thereby avoiding or reducing manual participation to the greatest extent and reducing or eliminating the pause of the machine in the next process.

[0005] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects:

[0006] 1. During repeated use and transportation, bobbins often collide with each other. The damage to the bobbin surface will become greater as the bobbin is used for a longer time. This is especially true for bobbins that are simply sprayed with different colors of paint on the surface. As a result, the color of the bobbin surface will not be as easy for industrial vision cameras to identify as when it was new, and the color classification accuracy is not high enough.

[0007] Industrial vision cameras are expensive devices that require meticulous care and frequent cleaning by staff. They are also expensive to purchase and maintain. Furthermore, due to issues like dust on the lens or insufficient light in the shooting environment, they cannot accurately identify the color of the bobbins, resulting in insufficient color classification accuracy.

[0008] 3. Since a bobbin turning rod is provided between the inner walls of the hopper, in order to ensure that each bobbin contacts the bobbin turning rod and turns direction, the maximum distance between the bobbin turning rod and the inner wall of the hopper cannot be greater than the maximum length of the bobbin. In actual use, in order to ensure that each bobbin falls vertically, the size of the hopper cannot be too large. However, if the bobbin does not fall in the bobbin channel in time, it is easy for the bobbin to get stuck in the narrow hopper, resulting in insufficient operation and the need for frequent machine stoppages for unblocking. Summary of the Invention

[0009] This application provides a recyclable pagoda-shaped bobbin and bobbin color separation and sorting recycling system to improve the following technical problems:

[0010] Common bobbins can only be sorted by color during bobbin recycling by capturing the color of the bobbin surface using industrial visual cameras or cameras. However, the equipment is expensive, with high purchase and maintenance costs, and the color sorting accuracy is not high enough. Moreover, when distinguishing between the large and small ends of common bobbins, if the bobbins do not fall into the bobbin channel in a timely manner, the bobbins can easily get stuck in the narrow hopper, resulting in unsmooth operation and requiring frequent machine stops for unblocking.

[0027] The NFC chip installed inside the tube is not easily damaged by transportation or high-frequency collisions, and the color identification information recorded on the NFC chip is not easily lost. When the color of the outer surface of the tube needs to be identified, only the corresponding scanning device is needed to scan and read the color identification information on the NFC chip. This is not limited by the degree of damage to the color of the outer surface of the tube or the lighting conditions, and the color classification accuracy is higher. Compared with industrial vision cameras, the scanning device required to scan and read the NFC chip has higher accuracy and relatively lower purchase and maintenance costs.

[0028] By installing a ferromagnetic identification part inside the tube body, during the yarn tube transportation process, the ferromagnetic identification part can be simply magnetically attracted by adding a magnet, thereby slowing down the transportation speed of the end with a smaller outer diameter of the tube body. Under the action of inertia or gravity, the transportation speed of the end with a larger outer diameter of the tube body generally remains unchanged, so that the tube body will rotate during the transportation process, and the yarn tubes will be sorted and transported out in the same direction as the large and small ends, which is less likely to cause material jamming, facilitates the recycling of the yarn tubes, and has a relatively high efficiency in distinguishing, sorting and transporting the large and small ends, making it suitable for industrial applications.

[0052] The following is combined with Figure 1-7 This application is described in further detail.

[0053] Example 1

[0054] The first embodiment of the present application discloses a recyclable pagoda-shaped bobbin 100. Figure 1 The recyclable pagoda-shaped bobbin 100 includes a tube body 11, a ferromagnetic identification part 13 and an NFC chip 12. The outer diameter of the tube body 11 gradually decreases from one end to the other end. The ferromagnetic identification part 13 and the NFC chip 12 are both installed inside the tube body 11. The ferromagnetic identification part 13 is adjacent to the end with the smaller outer diameter of the tube body 11. The ferromagnetic identification part 13 is used to be magnetically attracted to distinguish the large and small ends of the tube body 11. The NFC chip 12 is adjacent to the end with the larger outer diameter of the tube body 11. The NFC chip 12 has color identification information consistent with the color of the outer surface of the tube body 11.

[0055] The beneficial technical effects of the recyclable pagoda-shaped bobbin 100 of the embodiment of the present application are roughly as follows:

[0056] The NFC chip 12 installed in the tube body 11 is not easily damaged due to transportation or high-frequency collisions, and the color identification information recorded on the NFC chip 12 is not easily lost. When the color of the outer surface of the tube body 11 needs to be identified, only the corresponding scanning device is needed to scan and read the color identification information on the NFC chip 12. This is not limited by the degree of damage to the color of the outer surface of the tube body 11 or the lighting conditions, and the color classification accuracy is higher. The scanning device required to scan and read the NFC chip 12 is more accurate than an industrial visual camera, and the purchase and maintenance costs are relatively low.

[0057] By installing a ferromagnetic identification portion 13 inside the tube body 11, during the bobbin conveying process, the ferromagnetic identification portion 13 can be magnetically attracted by simply adding a magnet, thereby slowing down the conveying speed of the end of the tube body 11 with a smaller outer diameter. Under the action of inertia or gravity, the conveying speed of the end of the tube body 11 with a larger outer diameter generally remains unchanged, so that the tube body 11 will rotate during the conveying process, and the bobbin will be sorted and conveyed out in the same direction as the large and small ends, which is less likely to cause material jamming, facilitates the recycling of the bobbin, and has a relatively high efficiency in distinguishing, sorting and conveying the large and small ends, making it suitable for industrial applications.

[0058] In this embodiment, the tube body 11 includes a first tube 111, a second tube 112 and a third tube 113. The ends of the first tube 111 and the second tube 112 adjacent to each other are detachably assembled, and the ends of the first tube 111 and the third tube 113 adjacent to each other are detachably assembled. A first fixing structure for clamping the NFC chip 12 is formed between the first tube 111 and the second tube 112, and a second fixing structure for clamping the ferromagnetic identification part 13 is formed between the first tube 111 and the third tube 113.

[0059] In this embodiment, the first fixing structure includes: a first clamping plate 1111 provided in the end of the first tube 111 adjacent to the second tube 112, and a second clamping plate 1121 provided in the end of the second tube 112 adjacent to the first tube 111, and a first installation gap for accommodating the NFC chip 12 is formed between the first clamping plate 1111 and the second clamping plate 1121; the second fixing structure includes: a third clamping plate 1112 provided in the end of the first tube 111 adjacent to the third tube 113, and a fourth clamping plate 1131 provided in the end of the third tube 113 adjacent to the first tube 111, and a second installation gap for accommodating the ferromagnetic identification unit 13 is formed between the third clamping plate 1112 and the fourth clamping plate 1131.

[0060] The first and third clamping plates 1111 and 1112 are integrally formed within the first tube 111, the second and third clamping plates 1121 are integrally formed within the second tube 112, and the fourth and fourth clamping plates 1131 are integrally formed within the third tube 113. The first, second, third, and fourth clamping plates 1111, 1121, 1112, and 1131 are all circular and have different sizes. After the first and second tubes 111 and 112 are assembled, the first and second clamping plates 1111, 1121 cooperate to clamp the NFC chip 12 securely, effectively preventing the NFC chip 12 from shaking within the tube body 11 and effectively avoiding damage to the NFC chip 12 due to shaking and impact. After the first and third tubes 111 and 113 are assembled, the third and fourth clamping plates 1112, 1131 cooperate to clamp the ferromagnetic identification unit 13 securely, effectively preventing the ferromagnetic identification unit 13 from shaking within the tube body 11 and effectively preventing the ferromagnetic identification unit 13 from making abnormal noises during transportation.

[0061] In this embodiment, a circle of first sponge strips 14 is provided around the NFC chip 12, and the first sponge strips 14 are located in the first installation gap and pressed against the inner wall of the first tube 111 or the second tube 112; a circle of second sponge strips 15 is provided around the ferromagnetic identification part 13, and the second sponge strips 15 are located in the second installation gap and pressed against the inner wall of the first tube 111 or the third tube 113.

[0062] The first sponge strip 14 can be fixed to the peripheral side of the NFC chip 12 by glue. Since the first sponge strip 14 is deformable, it can further prevent the NFC chip 12 from shaking. The second sponge strip 15 can be fixed to the peripheral side of the ferromagnetic identification part 13 by glue. Since the second sponge strip 15 is deformable, it can further prevent the ferromagnetic identification part 13 from shaking.

[0063] In order to facilitate the installation of the NFC chip 12 and the ferromagnetic identification part 13 into the interior of the tube body 11, generally, the area of ​​the NFC chip 12 and the ferromagnetic identification part 13 will be smaller than the inner diameter of the tube body 11. Therefore, the additional design of the first sponge strip 14 and the second sponge strip 15 can further effectively prevent the NFC chip 12 and the ferromagnetic identification part 13 from shaking in the tube body 11, further effectively avoiding damage to the NFC chip 12 due to shaking and impact, better protecting the NFC chip 12, and reducing abnormal noise caused by shaking.

[0064] The first tube 111 is threadedly assembled with the second tube 112, and the first tube 111 is threadedly assembled with the third tube 113. The outer peripheral wall of the first tube 111 adjacent to the second tube 112 is provided with external threads, and the outer peripheral wall of the first tube 111 is provided with an external step that abuts the second tube 112. The inner peripheral wall of the second tube 112 adjacent to the first tube 111 is provided with internal threads, and the inner peripheral wall of the second tube 112 is provided with an internal step that abuts the first tube 111. The inner peripheral wall of the first tube 111 adjacent to the third tube 113 is provided with internal threads, and the inner peripheral wall of the third tube 113 is provided with an internal step that abuts the first tube 111. The outer peripheral wall of the third tube 113 adjacent to the first tube 111 is provided with external threads, and the outer peripheral wall of the third tube 113 is provided with an external step that abuts the first tube 111.

[0065] Through the above technical solution, the tube body 11 is designed as a split structure, which can facilitate the staff to install the NFC chip 12 and the ferromagnetic identification part 13 into the inside of the tube body 11, thereby providing good protection for the NFC chip 12 and the ferromagnetic identification part 13, and effectively solving the problem of difficult installation of the NFC chip 12 and the ferromagnetic identification part 13.

[0066] In order to solve the problem of poor sealing between the first tube 111 and the second tube 112, a first sealing rubber ring 16 is sandwiched between the second tube 112 and the outer step, and a second sealing rubber ring 17 is sandwiched between the first tube 111 and the inner step. The first sealing rubber ring 16 and the second sealing rubber ring 17 can effectively prevent external water from entering the interior of the tube body 11 and contacting the NFC chip 12. The NFC chip 12 is not easily damaged by contact with water and has a longer service life.

[0067] In this embodiment, the connection between the first tube 111 and the second tube 112 and the third tube 113 is smoothly transitioned, so that the tube body 11 is less likely to have the problem of wire winding and wire jamming due to the split design.

[0068] Specifically, the NFC chip 12 and the ferromagnetic identification part 13 are both located on the cross section of the tube body 11 (that is, the central axis of the tube body 11 is perpendicular to the NFC chip 12 and the ferromagnetic identification part 13). The ferromagnetic identification part 13 is a magnet sheet or a metal sheet. The distance H between the NFC chip 12 and the end with the larger outer diameter of the tube body 11 is 1-2 cm. The design of the above distance H allows the staff to observe whether the second splint 1121 and the NFC chip 12 in the tube body 11 are damaged at any time.

[0069] To ensure that the information on the NFC chip 12 can be quickly scanned and read, the wall thickness of the tube body 11 is between 3 and 5 mm, and the thickness of the first and second plywood 1111 and 1121 is between 2 and 4 mm. If the wall thickness of the tube body 11 and the thickness of the first and second plywood 1111 and 1121 are too thick, it will directly make it difficult to quickly scan and read the information on the NFC chip 12. Therefore, the above thickness design provides high structural strength without blocking the transmission of scanned data, making it less susceptible to damage due to impact, and providing better protection for the NFC chip 12.

[0070] Example 2

[0071] The second embodiment of the present application discloses a recyclable pagoda-shaped bobbin 100. Figure 2 , which differs from Example 1 in that:

[0072] The first tube 111 and the second tube 112 are plug-connected and assembled. An annular slot is provided at the end of the first tube 111 adjacent to the second tube 112 , and an insert ring is provided at the end of the second tube 112 adjacent to the first tube 111 . The insert ring is inserted into the annular slot.

[0073] Through the above technical solution, the tube body 11 is designed as a split structure, which can facilitate the staff to install the NFC chip 12 inside the tube body 11, thereby providing good protection for the NFC chip 12 and effectively solving the problem of difficult installation of the NFC chip 12.

[0074] To address the issue of poor sealing between the first tube 111 and the second tube 112, a third sealing rubber ring 18 is provided between the plug-in ring and the bottom of the annular slot. The third sealing rubber ring 18 effectively prevents external water from entering the tube body 11 and contacting the NFC chip 12. This prevents the NFC chip 12 from being damaged by water, extending its service life.

[0075] The first tube 111 and the third tube 113 are plug-in assembled. The end of the third tube 113 near the first tube 111 is provided with an annular slot, and the end of the first tube 111 near the third tube 113 is provided with a plug-in ring, which is plugged into the annular slot.

[0076] Through the above technical solution, the tube body 11 is designed as a split structure, which can facilitate the staff to install the ferromagnetic identification part 13 into the inside of the tube body 11, thereby providing good protection for the ferromagnetic identification part 13 and effectively solving the problem of difficult installation of the ferromagnetic identification part 13.

[0077] Example 3

[0078] The third embodiment of the present application discloses a yarn tube color separation and sorting recycling system. Figure 3 and Figure 4 and Figure 5 The bobbin color separation and sorting recycling system is used to sort the above-mentioned recyclable pagoda-shaped bobbins 100 in the direction of the large and small ends being consistent, sorted by color, and transported out. The bobbin color separation and sorting recycling system includes: a PLC control module, a frame 110, an inclined sorting hopper 300, a first conveyor belt 200 and a second conveyor belt 400 controlled and driven by a servo motor;

[0079] The first conveyor belt 200 and the second conveyor belt 400 are both arranged horizontally. The output end of the first conveyor belt 200 is higher than the input end of the second conveyor belt 400. The input port of the sorting hopper 300 is connected to the output end of the first conveyor belt 200, and the output port of the sorting hopper 300 is connected to the input end of the second conveyor belt 400.

[0080] The sorting hopper 300 is provided with an electromagnetic attraction mechanism 500 for magnetically attracting the ferromagnetic identification portion 13. When the ferromagnetic identification portion 13 is magnetically attracted by the electromagnetic attraction mechanism 500, the end of the tube body 11 with a larger outer diameter rotates in the sorting hopper 300.

[0081] The first conveyor belt 200 and the second conveyor belt 400 are both installed on the frame 110. The second conveyor belt 400 is used to intermittently drive the bobbin movement. The frame 110 is provided with a scanning and reading mechanism 700. The scanning and reading mechanism 700 is used to scan the recyclable pagoda-shaped bobbin 100 on the second conveyor belt 400 and read the color identification information. A plurality of bobbin outlets 1102 are provided on the side of the frame 110. A plurality of groups of tube pushing actuators 800 are also provided on the side of the frame 110. The tube pushing actuators 800 are arranged one-to-one corresponding to the bobbin outlets 1102 and are respectively arranged on both sides of the frame 110. The servo motor, the scanning and reading mechanism 700, and the tube pushing actuator 800 are all electrically connected to the PLC control module.

[0082] The beneficial technical effects of the bobbin color separation and recycling system of the embodiment of the present application are roughly as follows:

[0083] The NFC chip 12 installed in the tube body 11 is not easily damaged due to transportation or high-frequency collisions, and the color identification information recorded on the NFC chip 12 is not easily lost. When the color of the outer surface of the tube body 11 needs to be identified, only the corresponding scanning device is needed to scan and read the color identification information on the NFC chip 12. This is not limited by the degree of damage to the color of the outer surface of the tube body 11 or the lighting conditions, and the color classification accuracy is higher. The scanning device required to scan and read the NFC chip 12 is more accurate than an industrial visual camera, and the purchase and maintenance costs are relatively low.

[0084] When multiple bobbins of different colors are transferred one by one onto the second conveyor belt 400, the servo motor is started to convey the bobbins to the bottom of the scanning and reading mechanism 700. The scanning and reading mechanism 700 is started to scan and read the color identification information recorded on the NFC chip 12 in the bobbins, and transmit the read color identification information to the PLC control module. The PLC control module then controls the servo motor to start and convey the bobbins of the same color to the corresponding bobbin outlet 1102 according to the received color identification information, and synchronously controls the corresponding bobbin pushing actuator 800 to start until the bobbins are pushed into the bobbin outlet 1102 and then transferred away by a robot arm or a conveyor belt.

[0085] The NFC chip 12 installed in the tube body 11 is not easily damaged due to transportation or high-frequency collisions, and the color identification information recorded on the NFC chip 12 is not easily lost. When the color of the outer surface of the tube body 11 needs to be identified, it is only necessary to scan and read the color identification information on the NFC chip 12 through the scanning and reading mechanism 700. This is not limited by the degree of damage to the color of the outer surface of the tube body 11 or the lighting conditions, and the color classification accuracy is higher. Compared with industrial vision cameras, the scanning and reading mechanism 700 has higher accuracy and relatively low purchase and maintenance costs.

[0086] In this embodiment, the sorting hopper 300 includes a bottom plate 31 and side baffles 32 arranged on both sides of the bottom plate 31. The sorting hopper 300 is made of plastic or non-ferromagnetic material. The bottom plate 31 includes a rectangular portion 311 and an isosceles trapezoidal portion 312. The rectangular portion 311 is connected to the top of the isosceles trapezoidal portion 312. The width of the isosceles trapezoidal portion 312 gradually decreases from top to bottom, and the minimum width of the isosceles trapezoidal portion 312 is greater than the maximum outer diameter of the tube body 11.

[0087] Specifically, the electromagnetic suction mechanism 500 includes a fixed plate 51 and multiple electromagnets 52. The fixed plate 51 is fixed to the lower surface of the sorting hopper 300. The electromagnets 52 are fixed to the lower surface of the fixed plate 51. The length direction of the fixed plate 51 is arranged along the width direction of the sorting hopper 300. The multiple electromagnets 52 are arranged at intervals along the length direction of the fixed plate 51.

[0088] The electromagnetic suction mechanism 500 is located exactly at the junction of the rectangular portion 311 and the isosceles trapezoidal portion 312. The magnetic attraction range formed by the multiple electromagnets 52 is in the shape of a strip, and the length of the strip-shaped magnetic attraction area is at least 75% of the width of the rectangular portion 311. Therefore, each bobbin that slides off the sorting hopper 300 will be magnetically attracted by the electromagnetic suction mechanism 500, preventing the bobbin from being missed and rotated.

[0089] The electromagnetic suction mechanism 500 designed above has a simple structure and is easy to install. After the electromagnet 52 is activated for a certain period of time and the bobbin rotates into position, the electromagnet 52 can be turned off, thereby facilitating the bobbin with the large end rotated downward to slide smoothly onto the second conveyor belt 400.

[0090] In order to facilitate the smooth rotation of the bobbin under the premise that one end is magnetically attracted and to prevent the material from getting stuck, a miniature vibration motor 600 is respectively installed on the top and bottom of the lower surface of the sorting hopper 300 to assist the bobbin in rotating under the action of gravity, to prevent the material from getting stuck and to ensure smoother operation.

[0091] Side panels 1101 higher than the conveying surface of the second conveyor belt 400 are provided on both sides of the frame 110. The bobbin outlets 1102 are provided on the side panels 1101. The side panels 1101 are used to prevent the bobbins from falling from the sides.

[0092] In order to avoid interference between two adjacent colored yarn tubes during the classification and collection process, the two adjacent yarn tube outlets 1102 are respectively located on both sides of the frame 110, and the two adjacent groups of push-tube actuators 800 are respectively located on both sides of the frame 110. In addition, the above-mentioned staggered design provides a larger operating space for the staff to repair and maintain the push-tube actuator 800, which is more practical.

[0093] In order to prevent the bobbins on the second conveyor belt 400 from getting too close to the side of the frame 110, thereby effectively preventing the scanning and reading mechanism 700 from being unable to scan the bobbins and effectively preventing the tube pushing actuator 800 from being unable to push the bobbins, a material guiding mechanism 900 is provided on the frame 110. The material guiding mechanism 900 is used to guide the messy bobbins on the second conveyor belt 400 to the middle position of the second conveyor belt 400.

[0094] In this embodiment, the material guiding mechanism 900 includes two inclined guide plates 91 and two springs 92. One end of the two inclined guide plates 91 is respectively hinged to the frame 110 (specifically, the inner wall of the side panel 1101), and the inclined guide plates 91 are arranged adjacent to the conveying surface of the second conveyor belt 400. There is no gap or a small gap between the inclined guide plates 91 and the second conveyor belt 400, thereby preventing the yarn tube from running to both sides during the conveying process. The two inclined guide plates 91 are arranged in an eight-shaped shape.

[0095] The spring 92 is connected between the side of the frame 110 and the other end of the oblique guide plate 91, so that even if the oblique guide plate 91 is squeezed or hit by the bobbin, the oblique guide plate 91 can also rotate to a certain extent, thereby effectively protecting the bobbin from being damaged by a large impact, especially when the bobbin has an NFC chip 12 inside, the protection effect is better.

[0096] Please refer to Figure 5 and Figure 6 The scanning and reading mechanism 700 includes a gate-shaped bracket 71, a lifting power piece 72 and an NFC scanning unit 73. The bottom two sides of the gate-shaped bracket 71 are respectively installed on the two sides of the frame 110. The lifting power piece 72 is installed on the top of the gate-shaped bracket 71 and the output shaft of the lifting power piece 72 is arranged downward. The output shaft of the lifting power piece 72 is connected to the NFC scanning unit 73. The lifting power piece 72 is used to drive the NFC scanning unit 73 to move closer to or away from the second conveyor belt 400; the NFC scanning unit 73 includes a mounting plate 731 and a plurality of NFC scanning guns 732. The plurality of NFC scanning guns 732 are installed at intervals on the lower surface of the mounting plate 731. The upper surface of the mounting plate 731 is connected to the output shaft of the lifting power piece 72.

[0097] Moreover, there are multiple lifting power parts 72 that are started or closed synchronously. The lifting power parts 72 are servo cylinders (can also be servo oil cylinders or servo electric push rods). As long as the lifting power parts 72 are controlled by the PLC control module, it will be fine.

[0098] In order to prevent the NFC scanner 732 from missing the bobbin, the scanning range formed by the multiple NFC scanners 732 is at least half of the width of the second conveyor belt 400 .

[0099] The scanning and reading mechanism 700 designed above has a simple structure, is easy to manufacture and operate, and operates stably. When performing scanning, it can be as close as possible to the bobbin on the second conveyor belt 400, and the scanning and reading accuracy is higher.

[0100] Please refer to Figure 5 and Figure 7 The tube pushing actuator 800 includes a mounting bracket 81, a tube pushing power member 82 and a tube pushing unit 83. The mounting bracket 81 is mounted on the outer side of the frame 110. The tube pushing power member 82 is mounted on the mounting bracket 81. The tube pushing unit 83 is connected to the output shaft of the tube pushing power member 82. The tube pushing power member 82 is used to drive the tube pushing unit 83 toward or away from the bobbin outlet 1102. The tube pushing unit 83 includes a hard plate 831 and a rubber plate 832. The hard plate 831 is connected to the output shaft of the tube pushing power member 82. The rubber plate 832 is arranged on the side of the hard plate 831 close to the bobbin outlet 1102.

[0101] Moreover, a concave arc surface 8321 is provided on one side of the rubber plate 832 close to the bobbin outlet 1102, so that when the bobbin is pushed, the bobbin is not easily out of the pushing range of the rubber plate 832, and the pushing is more accurate, the success rate is higher, and the operation is more stable.

[0102] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
