Description

Technical Field

[0001] This application relates to the field of felt-covered needle punching, and in particular to a felt-covered curved surface needle punching machine. Background Technology

[0002] Felt is a textile material formed by binding wool fibers together through physical or chemical means. Shaped felt is a type of felt, specifically designed to meet particular design requirements and featuring a curved surface. Felt covers are another type of shaped felt, with curved ends.

[0003] During the production and processing of felt covers, needle punching is usually performed to make the fiber structure on the felt cover more tightly connected. Currently, in existing needle punching methods, flat felt is usually needle punched. This is done by mounting puncture needles on a liftable mounting plate, and using a needle punching power component to drive the mounting plate to rise and fall, so that the puncture needles on the mounting plate approach the felt and perform needle punching on the surface of the felt.

[0004] However, for felt sleeves, which have curved ends, the method of needle-punching the felt by driving the mounting plate to rise and fall with the needle-punching power component cannot needle-punch the curved end of the felt sleeve, making the needle-punching process of the felt sleeve inconvenient. Summary of the Invention

[0005] In order to facilitate the needle punching process of felt sleeves, this application provides a needle punching machine for curved surfaces of felt sleeves.

[0006] This application provides a felt-sleeved curved surface needle punching machine, which adopts the following technical solution:

[0007] A felt sleeve curved surface needle punching machine includes a needle punching frame, on which a needle punching device is provided. The needle punching device includes a peripheral needle punching mechanism and an end face needle punching mechanism. The peripheral needle punching mechanism is used to needle punch the peripheral sidewall of the felt sleeve, and the end face needle punching mechanism is used to needle punch the end face of the felt sleeve. The needle punching frame is also provided with a workpiece rotating mechanism, which is used to drive the felt sleeve to rotate.

[0008] By adopting the above technical solution, the felt sleeve is driven to rotate by the workpiece rotation mechanism, the peripheral side wall of the felt sleeve is needled by the peripheral needle punching mechanism, and the arc-shaped surface of the end face of the felt sleeve is needled by the end face needle punching mechanism, thereby facilitating the needle punching process of the felt sleeve.

[0009] In one specific implementation, the peripheral acupuncture mechanism includes a peripheral mounting frame, a height adjustment assembly, and a peripheral acupuncture assembly. The mounting frame is mounted on the acupuncture frame. The height adjustment assembly includes a height drive, a height adjustment screw, and a height transmission component. Both the height drive and the height transmission component are mounted on the acupuncture frame, and the height drive is connected to the height transmission component. The height adjustment screw is mounted on the acupuncture frame and is connected to the height transmission component. The height adjustment screw is also connected to the peripheral mounting frame. The peripheral acupuncture assembly is mounted on the peripheral mounting frame.

[0010] By adopting the above technical solution, the height drive component drives the height transmission component to move, which in turn drives the height adjustment screw to move up and down, thereby driving the mounting frame to move up and down, and in turn driving the peripheral needle punching component to move up and down, thus facilitating the adjustment of the height of the peripheral needle punching component.

[0011] In one specific implementation, the peripheral acupuncture assembly includes an acupuncture power assembly, a needle beam, and peripheral needles. The acupuncture power assembly is mounted on a peripheral mounting bracket, the needle beam is mounted on the acupuncture power assembly, and the peripheral needles are mounted on the bottom wall of the needle beam.

[0012] By adopting the above technical solution, the height of the needle beam is adjusted using a worm gear box, which facilitates the adjustment of the distance between the peripheral needles and the felt sleeve, thereby facilitating the peripheral needles to perform needle piercing treatment on the side wall of the felt sleeve.

[0013] In one specific implementation, the end-face needle-punching mechanism includes a triangular support, an angle adjustment component, a movement adjustment component, and an end-face needle-punching component. The triangular support is mounted on a needle-punching frame. The angle adjustment component includes a first driving member, a first transmission member, a first lead screw, a second driving member, a second transmission member, and a second lead screw. The first driving member and the first transmission member are mounted at one end of the triangular support, and the first transmission member is connected to the first driving member. The first lead screw is mounted on the triangular support and is connected to the first transmission member, with one end extending towards the felt sleeve. The second driving member and the second transmission member are mounted at the other end of the triangular support. The second lead screw is mounted on the triangular support near the second transmission member, and is connected to the second transmission member. One end of the second lead screw extends towards the felt sleeve, and the axis of the second lead screw is parallel to the axis of the first lead screw. The movement adjustment component is mounted on the triangular support, and both the first and second lead screws are connected to the movement adjustment component. The end-face needle-punching component is mounted on the movement adjustment component.

[0014] By adopting the above technical solution, the first driving component drives the first transmission component to move, so that the first transmission component drives the first lead screw to move, and the second driving component drives the second transmission component to move, so that the second transmission component drives the second lead screw to move, thereby adjusting the angle between the moving adjustment component and the arc-shaped surface at the end of the felt sleeve, so that the end face needle punching component on the moving adjustment component can be aligned with the end face of the felt sleeve, thereby performing needle punching treatment on the arc-shaped part of the end face of the felt sleeve.

[0015] In one specific implementation, the movable adjustment assembly includes a movable bracket, a movable lead screw, and a movable drive component. One end of the movable bracket is connected to the end of a first lead screw, and the other end of the movable bracket is connected to the end of a second lead screw. The movable lead screw is rotatably mounted on the movable bracket, and the axis of the movable lead screw intersects the axis of the first lead screw. The movable drive component is mounted on the movable bracket and is connected to one end of the movable lead screw. The end-face needle-punching assembly is mounted on the movable bracket and is also connected to the movable lead screw.

[0016] By adopting the above technical solution, the moving screw is driven to rotate by the moving drive component, thereby causing the moving screw to move the end face needle punching assembly along the moving bracket, thereby moving the end face needle punching assembly to a suitable position, thus facilitating the end face needle punching assembly to perform needle punching treatment on the end face of the felt sleeve.

[0017] In one specific implementation, the length of the movable lead screw is such that the end-face needle-punching assembly moves along the end face of the felt sleeve.

[0018] By adopting the above technical solution, the moving lead screw is set to a sufficiently long field so that the end face needle punching assembly can completely needle punch the arc-shaped surface at the end of the felt sleeve.

[0019] In one specific implementation, the end-face needle punch assembly includes a housing, a needle punching drive, a needle plate, and an end-face needle. The housing is mounted on a movable support and is also threadedly connected to a movable lead screw. The needle punching drive is mounted on the housing, the needle plate is mounted on the housing and connected to the needle punching drive, and the end-face needle is mounted on the needle plate.

[0020] By adopting the above technical solution, the rotation of the moving screw drives the housing to move to a suitable position, and then the needle plate is driven to move by the needle-punching drive component, so that the end face needles on the needle plate can be needle-punched on the arc-shaped curved surface of the felt sleeve end face.

[0021] In one specific implementation, the workpiece rotation mechanism includes a rotating bracket, a mold shaft, a rotation drive assembly, and a positioning assembly. The rotating bracket is mounted on the needle punching frame. The rotation drive assembly includes a power source and a rotating rod, both of which are mounted on the rotating bracket. The rotating rod is connected to the power source. The mold shaft is rotatably mounted on the rotating bracket and is detachably connected to the rotating rod. The positioning assembly is mounted on the rotating bracket and is connected to the mold shaft.

[0022] By adopting the above technical solution, the mold shaft is installed on the rotating frame and connected to the rotating rod. The mold shaft is positioned by the positioning component, and the rotating rod is driven to rotate by the power source, so that the rotating rod drives the mold shaft to rotate, thereby driving the felt sleeve on the mold shaft to rotate, thus facilitating the needle punching device to perform needle punching on the felt sleeve.

[0023] In one specific implementation, the positioning assembly includes a positioning handwheel, a positioning screw, a positioning plate, and a positioning rod. One end of the positioning screw is rotatably mounted on a rotating bracket, the positioning handwheel is coaxially mounted on the other end of the positioning screw, the positioning plate is threaded onto the positioning screw, and the positioning rod is mounted on the rotating bracket. One end of the positioning rod is detachably connected to the mold shaft, and the other end is connected to the positioning plate.

[0024] By adopting the above technical solution, when the mold shaft is installed on the rotating frame, the positioning handwheel is rotated, which drives the positioning screw to rotate, thereby driving the positioning plate to move. The positioning plate then drives the positioning rod to be inserted into the mold shaft, thereby positioning the mold shaft and maintaining the stability of the mold shaft rotation.

[0025] In one specific implementation, the needle-punching frame is further equipped with a winding device, which includes a traveling mechanism and a winding mechanism. The traveling mechanism includes a traveling frame, an upper traveling drive assembly, and a lower traveling drive assembly. The lower traveling drive assembly and the traveling frame are both mounted on the needle-punching frame, and the traveling frame is connected to the lower traveling drive assembly. The upper traveling assembly is mounted on the traveling frame. The winding mechanism includes a winding tube and a winding lead. The winding tube and the winding lead are both mounted on the upper traveling assembly, and the winding lead is used to guide the wire on the winding tube to the felt sleeve.

[0026] By adopting the above technical solution, after the felt sleeve is needle-punched, the lower travel drive assembly drives the traveling frame to move towards the felt sleeve, thereby moving the winding tube and winding lead to the felt sleeve. The winding lead guides the wire on the tube to the felt sleeve, thereby winding the felt sleeve. The upper travel drive assembly drives the winding tube and winding lead to move along the circumferential wall of the felt sleeve, thus facilitating the winding of the entire felt sleeve.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. This application improves the convenience of needle punching the felt cover by setting a needle punching device to facilitate needle punching treatment on the arc-shaped curved surfaces of the periphery and ends of the felt cover.

[0046] The present application will be further described in detail below with reference to the accompanying drawings.

[0047] Example 1:

[0048] This application discloses a felt-covered curved surface needle punching machine, referring to... Figure 1 The device includes a needle-punching frame 1, on which a needle-punching device, a workpiece rotation mechanism 4, and a winding device 5 are mounted. The workpiece rotation mechanism 4 is located below the needle-punching device and is used to drive the felt sleeve 8 to rotate. The winding device 5 is located on one side of the workpiece rotation mechanism 4 and is used to wind wire onto the felt sleeve 8.

[0049] Reference Figure 1 The workpiece rotating mechanism 4 drives the felt sleeve 8 to rotate, and then the needle punching device performs needle punching on the peripheral wall and end of the felt sleeve 8. After the needle punching is completed, the winding device 5 winds the wire onto the felt sleeve 8. After the winding is completed, the felt sleeve 8 is removed from the needle punching frame 1 and cut along the middle part of the felt sleeve 8 to divide the felt sleeve 8 into two equal parts, thereby realizing the processing of two felt sleeves 8 at one time.

[0050] Reference Figure 1 and Figure 2 The needle-punching frame 1 is also equipped with a lifting mechanism 6, which is used to drive the needle-punching device to move up and down. The lifting mechanism 6 includes a lifting frame 61 and a lifting drive assembly 62. The lifting drive assembly 62 includes a lifting motor 621, a lifting screw 622, and a lifting transmission component 623. The lifting motor 621 is fixedly installed at the upper end of the needle-punching frame 1, and its output shaft is located in the horizontal direction. The lifting transmission component 623 is installed on the needle-punching frame 1 near the lifting motor 621. The lifting transmission component 623 uses a worm gear drive, and the worm in the lifting transmission component 623 is coaxially connected to the output shaft of the lifting motor 621. The lifting screw 622 is slidably installed on the needle-punching frame 1 in the vertical direction, and is coaxially arranged with the worm gear in the lifting transmission component 623. The lifting screw 622 and the worm gear in the lifting transmission component 623 are also threadedly connected.

[0051] Reference Figure 1 and Figure 2 The lifting frame 61 is slidably mounted on the needle-punching frame 1 in a vertical direction. The upper end of the lifting screw 622 is also rotatably connected to the lifting frame 61. The needle-punching device is mounted on the lifting frame 61.

[0052] Reference Figure 1 and Figure 2 The lifting motor 621 drives the lifting transmission component 623 to move, which in turn causes the lifting transmission component 623 to move the lifting screw 622 in the vertical direction, thereby driving the lifting frame 61 to rise and fall, and thus driving the needle-punching device to rise and fall.

The needle beam 232 is vertically mounted on the lower end of the peripheral mounting bracket 21 and is connected to the needle power component 231. The peripheral needles 233 are detachably mounted on the bottom wall of the needle beam 232.

[0055] Reference Figure 1 and Figure 2 The height drive component 221 drives the height transmission component 223 to move, causing the height transmission component 223 to drive the height adjusting screw 222 to rise and fall along its axis. This, in turn, causes the peripheral mounting bracket 21 to rise and fall, which in turn causes the needle beam 232 mounted on the peripheral mounting bracket 21 to rise and fall, thereby adjusting the height of the needle beam 232 to adjust the puncture depth of the peripheral needles 233. Then, the needle beam 232 is driven by the needle power component to reciprocate, causing the needle beam 232 to drive the peripheral needles 233 to perform needle puncture treatment on the felt sleeve 8.

[0064] Reference Figure 6 and Figure 7The mold shaft 42, equipped with the felt sleeve 8, is mounted on the rotating bracket 41, with one end of the mold shaft 42 coaxially connected to the rotating rod 434. By rotating the positioning handwheel 441, the positioning screw 442 is rotated, which in turn drives the positioning plate 443 to move, thereby moving the positioning rod 444 towards the mold shaft 42, so that the positioning rod 444 is inserted into the positioning hole, thus positioning the mold shaft 42. Then, the power source 431 drives the rotating drive wheel 432 to rotate, which in turn drives the rotating transmission wheel 433 to rotate via the rotating belt, thereby driving the rotating rod 434 to rotate, which in turn drives the mold shaft 42 to rotate, and thus drives the felt sleeve 8 on the mold shaft 42 to rotate.

[0065] Reference Figure 8 The winding device 5 includes a traveling mechanism 51 and a winding mechanism 52. The traveling mechanism 51 includes a traveling frame 511, a lower traveling drive assembly, and an upper traveling drive assembly. The lower traveling drive assembly includes a lower traveling motor 512, a first traveling lead screw 513, and a second traveling lead screw 514. The first traveling lead screw 513 is rotatably mounted on the lower end of the needle-punching frame 1, and the axis of the first traveling lead screw 513 is perpendicular to the axis of the mold shaft 42. The lower traveling motor 512 is fixedly mounted on the lower end of the needle-punching frame 1, and the output shaft of the lower traveling motor 512 is coaxially connected to the end of the first traveling lead screw 513 away from the mold shaft 42. The other end of the first traveling lead screw 513 is coaxially mounted with a traveling drive wheel 515. The second travel screw 514 is also rotatably mounted on the lower end of the needle-punching frame 1, and the axis of the second travel screw 514 is parallel to the axis of the first travel screw 513. A travel transmission wheel 516 is coaxially mounted on the end of the second travel screw 514 near the mold shaft 42. The travel drive wheel 515 and the travel transmission wheel 516 are connected by a travel belt. The travel frame 511 is slidably mounted on the needle-punching frame 1, and both the first travel screw 513 and the second travel screw 514 are threadedly connected to the lower end of the travel frame 511.

[0066] Reference Figure 8 and Figure 9 The vertical travel drive assembly includes an L-shaped bracket 517, an upper travel motor 518, a travel gear 519, and a travel rack 5110. The horizontal section of the L-shaped bracket 517 is slidably mounted on the upper end of the travel frame 511, and the vertical section extends downwards. The sliding path of the L-shaped bracket 517 is parallel to the axis of the mold shaft 42. The travel rack 5110 is fixedly mounted on the upper end of the travel frame 511, and the axis of the travel rack 5110 is parallel to the axis of the mold shaft 42. The upper travel motor 518 is fixedly mounted on the side wall of the L-shaped bracket 517. The travel gear 519 is coaxially mounted on the output shaft of the upper travel motor 518, and the travel gear 519 meshes with the travel rack 5110.

[0067] Reference Figure 9The winding mechanism 52 includes a winding tube 521 and a winding lead 522. The winding tube 521 is rotatably mounted on one side of the vertical section of the L-shaped bracket 517. A brake is also coaxially mounted on the winding tube 521. In this embodiment, the brake is a magnetic powder brake. The winding lead 522 is detachably mounted on the side wall of the vertical section of the L-shaped bracket 517 near the mold shaft 42. The winding lead 522 is used to guide the wire on the winding tube 521 onto the felt sleeve 8.

[0068] Reference Figure 8 and Figure 9 The first travel screw 513 is driven to rotate by the lower travel motor 512, which in turn drives the travel drive wheel 515 to rotate. The travel drive wheel 515 drives the travel transmission wheel 516 to rotate through the travel belt, which in turn drives the second travel screw 514 to rotate. This causes the travel frame 511 to move towards the mold shaft 42, which in turn causes the L-shaped bracket 517 to move closer to the mold shaft 42. Then, the wire on the winding tube 521 is guided to the rotating felt sleeve 8 by the winding lead 522. The upper travel motor 518 drives the travel gear 519 to rotate, so that the travel gear 519 moves along the travel rack 5110, thereby driving the L-shaped bracket 517 to move along the axis of the travel rack 5110, thereby driving the winding lead 522 to move along the axis of the mold shaft 42, so that the wire can be wound on the felt sleeve 8. After the winding is completed, the winding tube 521 is braked by the brake, and the travel mechanism 51 drives the winding lead 522 to move away from the mold shaft 42, thereby facilitating the completion of the winding action.

[0069] The working principle of this embodiment is as follows: The mold shaft 42, which is equipped with the felt sleeve 8, is mounted on the rotating bracket 41. The mold shaft 42 is driven to rotate by the workpiece rotation mechanism 4, thereby causing the felt sleeve 8 to rotate. The lifting frame 61 is driven to descend by the lifting mechanism 6, thereby causing the needle-punching device to descend to a suitable height. Then, the height of the needle beam 232 is adjusted by the height adjustment component 22, thereby adjusting the puncture depth of the peripheral needle 233. The position of the end face needle-punching component 34 is adjusted by the angle adjustment component 32 and the movement adjustment component 33, so that the end face needle 349 is aligned with the curved surface of the end of the felt sleeve 8. Then, the peripheral needle 233 is driven by the needle-punching power component to perform needle-punching treatment on the peripheral wall of the felt sleeve 8, and the end face needle 349 is driven by the end face needle-punching component 34 to perform needle-punching treatment on the curved surface of the end of the felt sleeve 8.

[0070] After the needle puncture treatment is completed, the lifting mechanism 6 drives the lifting frame 61 to rise, thereby raising the needle puncture device and moving it away from the felt cover 8.

[0071] Then, the traveling mechanism 51 drives the traveling frame 511 to move towards the felt sleeve 8, thereby bringing the winding lead 522 close to the felt sleeve 8. The winding lead 522 guides the wire from the winding tube 521 onto the felt sleeve 8, thus winding the wire onto the felt sleeve 8. The traveling mechanism 51 then drives the winding lead 522 to move along the axis of the mold shaft 42, thereby winding the wire onto the felt sleeve 8. After winding is completed, the traveling mechanism 51 drives the winding lead 522 to move away from the felt sleeve 8, and then the complete felt sleeve 8 is cut into two parts from the middle, thus creating two identical felt sleeves 8. This allows for the simultaneous processing of two felt sleeves 8, improving the needle punching efficiency of the felt sleeves 8.

[0072] Example 2:

[0073] Reference Figure 10 and Figure 11 To reduce the likelihood of needle breakage after prolonged use of the peripheral needle 233, the difference between Embodiment 2 and Embodiment 1 is that the needle beam 232 is further equipped with a quick-release mechanism 7 for disassembling the peripheral needle 233. The quick-release mechanism 7 includes a quick-release needle plate 71 and a quick-release assembly 72. The quick-release assembly 72 includes a quick-release rod 721, a quick-release hook 722, and a quick-release nut 724. Several quick-release holes 2321 are provided on the bottom wall of the needle beam 232. Several quick-release posts 711 corresponding to the quick-release holes 2321 are fixedly installed on the top wall of the quick-release needle plate 71. The quick-release posts 711 are inserted into the quick-release holes 2321. The peripheral needle 233 is fixedly installed on the bottom wall of the quick-release needle plate 71.

[0074] Reference Figure 11 and Figure 12 The quick-release post 711 has a locking interface 712 on its side wall. One end of the quick-release hook 722 is rotatably installed in the quick-release hole 2321, and the rotation axis of the quick-release hook 722 is located above the quick-release post 711. The other end of the quick-release hook 722 is engaged with the locking interface 712, and the end of the quick-release hook 722 engaged with the locking interface 712 abuts against the side wall of the quick-release post 711 at the locking interface 712. The quick-release rod 721 is slidably installed on the needle beam 232 near the quick-release hole 2321. The axis of the quick-release rod 721 is parallel to the axis of the needle beam 232, and the quick-release rod 721 is located above the quick-release post 711. Both ends of the quick-release rod 721 extend outward from the needle beam 232. A push rod 723 is fixedly installed at the upper end of the quick-release hook 722. The axis of the push rod 723 is perpendicular to the axis of the quick-release rod 721. A sliding hole 7211 is provided on the bottom wall of the quick-release rod 721 for the push rod 723 to slide. The push rod 723 is slidably installed in the sliding hole 7211.

[0075] Reference Figure 11 and Figure 12A limiting plate 726 is fixedly installed at one end of the quick-release lever 721 outside the pin beam 232. The limiting plate 726 is located on the side of the quick-release post 711 away from the locking interface 712. A quick-release spring 725 is also installed on the quick-release lever 721. One end of the quick-release spring 725 abuts against the side wall of the limiting plate 726, and the other end abuts against the side wall of the pin beam 232. A pull rod 727 is fixedly installed at the other end of the quick-release lever 721. A baffle 728 is fixedly installed at the end of the pull rod 727 away from the quick-release lever 721. A quick-release thread is also provided on the pull rod 727. A quick-release nut 724 is installed on the quick-release lever 721 through the quick-release thread, and the side wall of the quick-release nut 724 abuts against the side wall of the pin beam 232.

[0076] Reference Figure 11 and Figure 12 When a new peripheral needle 233 needs to be installed on the needle beam 232, the quick-release pin 711 on the quick-release needle plate 71 is inserted into the quick-release hole 2321. At this time, the quick-release spring 725 is in a relaxed state. Then, the quick-release nut 724 is tightened, which causes the quick-release nut 724 to drive the pull rod 727 to move. This causes the pull rod 727 to drive the quick-release rod 721 to move, which causes the limiting plate 726 at the end of the quick-release rod 721 to compress the quick-release spring 725. As the quick-release rod 721 moves, it pushes the push rod 723 through the sliding hole 7211. This causes the push rod 723 to drive the quick-release hook 722 to rotate counterclockwise, so that the lower end of the quick-release hook 722 rotates to engage with the locking interface 712 of the quick-release pin 711, thereby limiting the quick-release pin 711. When the quick-release nut 724 moves along the pull rod 727 to abut against the end of the quick-release rod 721, the quick-release rod 721 moves to the locked position. At this time, the end of the quick-release nut 724 abuts against the side wall of the needle beam 232, and the lower end of the quick-release hook 722 abuts against the side wall of the quick-release post 711 located at the locking interface 712, thereby limiting the quick-release post 711. At this time, the quick-release needle plate 71 is stably installed on the needle beam 232 through the quick-release post 711.

[0077] Reference Figure 12 and Figure 13 When it is necessary to disassemble the peripheral needle 233, loosen the quick-release nut 724. At this time, the quick-release spring 725 returns from the compressed state to the relaxed state, thereby pushing the limiting plate 726 to move away from the needle beam 232, thereby driving the quick-release rod 721 to move. The quick-release rod 721 pushes the push rod 723 to move away from the quick-release nut 724 through the sliding hole 7211. The push rod 723 drives the quick-release hook 722 to rotate clockwise, thereby separating the lower end of the quick-release hook 722 from the locking interface 712 of the quick-release post 711, thereby contacting the limiting of the quick-release post 711, so as to facilitate the removal of the quick-release needle plate 71 from the quick-release hole 2321.

[0078] The working principle of this embodiment is as follows: When it is necessary to disassemble the peripheral needle 233, loosen the quick-release nut 724 to restore the quick-release spring 725 to a relaxed state, thereby driving the quick-release rod 721 to move, which in turn drives the push rod 723 to move, thereby driving the quick-release hook 722 to rotate clockwise, thereby separating the quick-release hook 722 from the locking interface 712, thereby contacting the positioning of the quick-release post 711, and then pulling the quick-release post 711 out of the quick-release hole 2321 to complete the disassembly.

[0079] When a new peripheral needle 233 needs to be installed on the needle beam 232, the quick-release pin 711 on the quick-release needle plate 71 with the new peripheral needle 233 is inserted into the quick-release hole 2321, and then the quick-release nut 724 is tightened, so that the quick-release spring 725 is in a compressed state, thereby driving the quick-release rod 721 to move, thereby driving the push rod 723 to move, thereby driving the quick-release hook 722 to rotate counterclockwise, so that the lower end of the quick-release hook 722 engages with the locking interface 712, thereby positioning the quick-release pin 711, thus completing the installation of the new peripheral needle 233.

[0080] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
