Description

Technical Field

[0001] This application relates to the field of felt needle punching, and in particular to a needle punching machine for irregularly shaped felt sleeves. 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 with a curved structure made according to design requirements; felt sleeves are one such type of shaped felt, with the curved structure located at their ends.

[0003] Currently, in existing needle punching processes, the needle punching of felt is performed by mounting a puncture needle on a liftable mounting plate, connecting the mounting plate to a lifting reciprocating component, and driving the mounting plate to move up and down repeatedly, thereby causing the puncture needle on the mounting plate to perform reciprocating needle punching on the surface of the felt.

[0004] However, this method of needle-punching the felt by simply driving the mounting plate up and down is only suitable for needle-punching felt with a planar structure, and cannot needle-punch the curved surface of the felt sleeve, making the needle-punching process of the felt sleeve inconvenient. Summary of the Invention

[0005] In order to facilitate needle punching of felt sleeves, this application provides a needle punching machine for irregularly shaped felt sleeves.

[0006] This application provides a needle-punching machine for irregularly shaped felt sleeves, which adopts the following technical solution: A needle-punching machine for irregularly shaped felt covers includes a frame on which a needle-punching device is mounted. The needle-punching device includes a first needle-punching mechanism, a second needle-punching mechanism, and a third needle-punching mechanism. The first needle-punching mechanism is used to needle the peripheral sidewalls of the felt cover, the second needle-punching mechanism is used to needle the rounded corners at the ends of the felt cover, and the third needle-punching mechanism is used to needle the arc surface at the ends of the felt cover. A rotation device is also mounted on the frame to drive the felt cover to rotate around its axis.

[0007] By adopting the above technical solution, the felt sleeve is rotated by a self-rotating device, and then the side wall of the felt sleeve is needled by the first needle-punching mechanism, the original part at the end of the felt sleeve is needled by the second needle-punching mechanism, and the arc surface at the end of the felt sleeve is needled by the third needle-punching mechanism, thereby facilitating the needle-punching process of the felt sleeve and improving the needle-punching effect of irregularly shaped felt sleeves.

[0008] In one specific implementation, the acupuncture device further includes a main lifting mechanism, which includes a lifting frame and a lifting drive assembly. Both the lifting frame and the lifting drive assembly are mounted on the frame, and the lifting drive assembly is connected to the lifting frame. The first acupuncture mechanism, the second acupuncture mechanism, and the third acupuncture mechanism are all mounted on the lifting frame.

[0009] By adopting the above technical solution, when needle punching is required, the lifting frame is driven to descend by the lifting drive component, thereby driving the first needle punching mechanism, the second needle punching mechanism and the third needle punching mechanism on the lifting frame to descend, thus facilitating needle punching of the felt cover.

[0010] In one specific implementation, the first needle-piercing mechanism includes a cross frame, a first needle-piercing assembly, and a piercing lifting assembly. The cross frame and the piercing lifting assembly are both mounted on a lifting frame, and the piercing lifting assembly is connected to the cross frame. The first needle-piercing assembly includes a first needle plate, a first needle, and a lifting reciprocating component. The lifting reciprocating component is mounted on the cross frame, the first needle plate is mounted on the lifting reciprocating component, the first needle is mounted on the first needle plate, and the first needle is used to pierce the side wall of the felt sheath.

[0011] By adopting the above technical solution, the puncture lifting assembly drives the crossbeam to descend, which in turn drives the first needle plate to descend, which in turn drives the first needle to descend, thereby adjusting the puncture depth of the first needle into the side wall of the felt sleeve. Then, the lifting reciprocating component drives the first needle plate to reciprocate, thereby causing the first needle to reciprocate in puncture of the felt sleeve.

[0012] In one specific implementation, the second acupuncture mechanism includes a support, an angle adjustment component, a lateral movement component, and a second acupuncture component. The support is mounted on a lifting frame. The angle adjustment component includes a first lead screw, a first driving member, a first transmission member, and an adjusting plate. The first driving member and the first transmission member are both mounted on the support, and the first driving member is connected to the first transmission member. The first lead screw is mounted on the support and is connected to the first transmission member. The adjusting plate is rotatably mounted on the end of the first lead screw and is also slidably connected to the first lead screw. The lateral movement component is mounted on the adjusting plate, and the second acupuncture component is mounted on the lateral movement component.

[0013] By adopting the above technical solution, the first driving component drives the first transmission component to rotate, causing the first transmission component to move along its axis. This allows the first lead screw to move through the mounting plate and move the transverse component, thereby adjusting the angle. This makes it easier for the second needle assembly installed in the transverse component to align with the rounded curved surface at the end of the felt sleeve for needle punching.

[0014] In one specific implementation, the lateral movement assembly includes a lateral movement plate, a lateral movement drive, and a lateral movement screw. The lateral movement plate is mounted on the end of the first screw, the lateral movement drive and the lateral movement screw are mounted on the lateral movement plate, and the axis of the lateral movement screw is parallel to the axis of the lateral movement plate. The lateral movement drive is connected to the lateral movement screw. The second needle-punching assembly is mounted on the lateral movement plate and is connected to the lateral movement screw.

[0015] By adopting the above technical solution, the transverse drive component drives the transverse lead screw to rotate, thereby driving the second needle-punching assembly to move. This allows the second needle-punching assembly to move along the rounded corner at the end of the felt sleeve under the drive of the angle adjustment component and the transverse component, thus facilitating needle-punching of the entire rounded corner.

[0016] In one specific implementation, the second needle assembly includes a mounting block, a second needle plate, a connecting plate, a needle-piercing drive, and a second needle. The mounting block is mounted on a transverse sliding plate and is threadedly connected to a transverse sliding screw. The connecting plate and the needle-piercing drive are both mounted on the mounting block, and the needle-piercing drive is connected to the connecting plate. The needle-piercing drive is used to drive the connecting plate to move closer to or further away from the felt sleeve. The second needle plate is mounted on the mounting block and is connected to the connecting plate. The second needle is mounted on the second needle plate and is used to pierce the rounded corner at the end of the felt sleeve.

[0017] By adopting the above technical solution, the installation block is moved by the transverse lead screw, thereby adjusting the position of the second needle. Then, the connecting plate is driven to reciprocate by the needle drive component, thereby driving the second needle plate to reciprocate, thereby driving the second needle to perform needle punching treatment on the rounded corner of the felt sleeve end.

[0018] In one specific implementation, the needle drive includes a puncture motor and a drive shaft. The puncture motor is mounted on a mounting block, and the drive shaft is mounted on the mounting block. The puncture motor is connected to the drive shaft, and a protrusion is also mounted on the drive shaft. A deflection groove for the protrusion to rotate is provided on the connecting plate. The connecting plate is connected to the drive shaft through the deflection groove, and the protrusion is located in the deflection groove. The connecting plate is also connected to a second needle plate.

[0019] By adopting the above technical solution, the transmission shaft is driven to rotate by the puncture motor, which in turn drives the protrusion on the transmission shaft to rotate. This causes the protrusion to drive the connecting plate to move back and forth, thereby driving the second needle plate and the second needle on the second needle plate to perform reciprocating needle puncture treatment on the felt sleeve.

[0020] In one specific implementation scheme, the third needle-punching mechanism includes a mounting frame, an arc adjustment component, a displacement component, and a third needle-punching component. The mounting frame is mounted on a lifting frame, the arc adjustment component is mounted on the mounting frame, the displacement component is mounted on the arc adjustment component, and the third needle-punching component is mounted on the displacement component. The third needle-punching component is used to puncture the arc surface of the felt sleeve end face. The arc adjustment component is used to adjust the angle at which the third needle-punching component punctures the felt sleeve. The displacement component is used to drive the third needle-punching component to move along the radial direction of the felt sleeve.

[0021] By adopting the above technical solution, the angles of the displacement component and the third needle-punching component are adjusted by the arc adjustment component, and the position of the third needle-punching component is adjusted by the displacement component, so that the third needle-punching component can be aligned with the arc surface of the felt sleeve and perform the corresponding needle-punching treatment.

[0022] In one specific implementation, the rotation device includes a rotation drive mechanism and a mandrel. The rotation drive mechanism includes a rotation motor mounted on a frame. The mandrel is detachably mounted on the frame. The rotation motor is connected to the mandrel, and the mandrel is used to drive the felt sleeve to rotate.

[0023] By adopting the above technical solution, the spindle is driven to rotate by a self-rotating motor, which in turn drives the felt sleeve to rotate, thus facilitating the needle-punching process on the felt sleeve.

[0024] In one specific implementation, the frame is further provided with a winding device, which includes a winding mechanism and a moving mechanism. The moving mechanism is mounted on the frame. The winding mechanism includes a winding drum, a winding head, and a brake. The winding drum, winding head, and brake are all mounted on the moving mechanism. The brake is connected to the winding drum. The winding drum is used to wind the wire, and the winding head is used to guide the wire to the felt sleeve.

[0025] By adopting the above technical solution, after the needle punching process is completed, the winding head is moved towards the felt sleeve by the moving mechanism, and the winding head guides the wire on the winding drum to the felt sleeve, so that the wire is wound on the felt sleeve during the rotation of the felt sleeve.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. This application provides a needle-punching device to facilitate needle-punching of the sidewalls and curved surfaces of irregularly shaped felt covers, thereby making it easier to perform needle-punching on the felt covers.

[0054] Reference Figure 5 and Figure 6When the second needle-piercing mechanism 4 is working, the first driving member 422 drives the first transmission member 423 to rotate, causing the first transmission member 423 to rotate the first lead screw 421. This causes the first lead screw 421 to move away from the support 41 along its axis, which in turn causes the adjusting plate 424 to move one end of the transverse plate 431 away from the support 41. This causes the transverse plate 431 to move the mounting block 441 and the second needle 449 mounted on the mounting block 441. At the same time, the second driving member 427 drives the second transmission member 428 to rotate, causing the second transmission member 428 to rotate the second lead screw 426. This causes the second lead screw 426 to move away from the support 41 along its axis, which in turn causes the fixing plate 429 to move the other end of the transverse plate 431 away from or closer to the support 41. This adjusts the angle of the second needle 449 so that the second needle 449 can be aligned with the rounded corner of the end of the felt sleeve 8. Subsequently, the transverse drive 432 drives the transverse lead screw 433 to rotate, thereby causing the transverse lead screw 433 to move the mounting block 441 and the second needle 449 mounted on the mounting block 441, so that the second needle 449 can be moved to the appropriate position.

[0055] Reference Figure 5 and Figure 6 After the second needle 449 is adjusted, the puncture drive wheel 446 is driven to rotate by the puncture motor 444. The puncture drive wheel 446 drives the puncture transmission wheel 447 to rotate through the transmission belt. The puncture transmission wheel 447 drives the transmission shaft 445 to rotate. The transmission shaft 445 drives the protrusion 448 to rotate eccentrically, which drives the connecting plate 443 to reciprocate. The connecting plate 443 drives the second needle plate 442 to reciprocate. The second needle plate 442 drives the second needle 449 to reciprocate to needle the rounded corner of the felt sleeve 8.

[0061] Reference Figure 7 and Figure 8When the third needle-punching mechanism 5 is working, the third driving member 521 drives the third transmission member 522 to rotate, causing the third transmission member 522 to rotate the third lead screw 523. This causes the third lead screw 523 to move along its axis away from the mounting frame 51, which in turn causes the mounting plate 524 to move one end of the displacement plate 531 away from the mounting frame 51. This causes the displacement plate 531 to move the needle shell 541 and the third needle 549 mounted on the needle shell 541. At the same time, the fourth driving member 527 drives the fourth transmission member 528 to rotate, causing the fourth transmission member 528 to rotate the fourth lead screw 526. This causes the fourth lead screw 526 to move along its axis away from the mounting frame 51, which in turn causes the positioning plate 529 to move the other end of the displacement plate 531 away from or towards the mounting frame 51. This adjusts the angle of the third needle 549 so that the third needle 549 can be aligned with the arc surface at the end of the felt sleeve 8. Subsequently, the displacement drive 532 drives the displacement screw 533 to rotate, thereby causing the displacement screw 533 to move the needle shell 541 and the third needle 549 mounted on the needle shell 541, so that the third needle 549 can be moved to the appropriate position.

[0062] Reference Figure 8 and Figure 9 After the third needle 549 is adjusted, the power drive wheel 546 is driven to rotate by the power motor 544. The power drive wheel 546 drives the power transmission wheel 547 to rotate through the transmission belt. The power transmission wheel 547 drives the power shaft 545 to rotate. The power shaft 545 drives the power block 548 to rotate eccentrically. This drives the drive plate 543 to reciprocate. The drive plate 543 drives the third needle plate 542 to reciprocate. The third needle plate 542 drives the third needle 549 to perform reciprocating needle piercing treatment on the arc surface at the end of the felt sleeve 8.

[0065] Reference Figure 10 and Figure 11 The self-rotating motor 611 drives the self-rotating drive wheel 612 to rotate, which in turn drives the self-rotating transmission wheel 613 to rotate via a self-rotating belt. This, in turn, drives the self-rotating transmission rod 614 to rotate, which in turn drives the mandrel 62 to rotate, and consequently, drives the felt sleeve 8 on the mandrel 62 to rotate. Due to the inertia of the rotation of the mandrel 62, after the mandrel 62 has rotated through a certain angle, the brake disc 63 is braked by the brake component 64, which in turn brakes the self-rotating transmission rod 614, thus stopping the rotation of the mandrel 62 and facilitating the needle-punching treatment of the felt sleeve 8.

[0066] Reference Figure 12The winding device 7 includes a winding mechanism 71 and a moving mechanism 72. The moving mechanism 72 includes a moving frame 721, a moving motor 722, and a moving lead screw 723.

[0067] Reference Figure 12 and Figure 13 The winding mechanism 71 includes a winding frame 711, a winding motor 712, a winding gear 713, a winding rack 714, a winding drum 715, a winding head 716, and a brake 717. In this embodiment, the winding frame 711 is L-shaped. The horizontal section of the winding frame 711 is slidably mounted on the upper end of the movable frame 721, and the moving path of the winding frame 711 is parallel to the axis of the spindle 62. The vertical section of the winding frame 711 extends downward. The winding motor 712 is fixedly mounted on the side wall of the winding frame 711, and the output shaft of the winding motor 712 is perpendicular to the axis of the spindle 62. The winding gear 713 is coaxially mounted on the output shaft of the winding motor 712. The winding rack 714 is fixedly mounted on the movable frame 721, and the axis of the winding rack 714 is parallel to the axis of the spindle 62. The winding gear 713 meshes with the winding rack 714. The winding drum 715 is rotatably mounted on one side of the vertical section of the winding frame 711, and the brake 717 is coaxially mounted on one end of the winding drum 715. In this embodiment, the brake 717 is a magnetic powder brake 717. The winding head 716 is detachably mounted on the side of the vertical section of the winding frame 711 near the mandrel 62. The winding head 716 is used to guide the wire on the winding drum 715 onto the felt sleeve 8.

[0068] Reference Figure 12 and Figure 13When it is necessary to wind the felt sleeve 8, the movable motor 722 drives the movable lead screw 723 to rotate, which in turn drives the first pulley 725 to rotate. The first pulley 725 drives the second pulley 726 to rotate via the movable belt, which in turn drives the auxiliary lead screw 724 to rotate. This causes the movable frame 721 to move towards the mandrel 62, which in turn moves the winding frame 711 towards the mandrel 62. When the movable frame 721 is in position, the winding head 716 guides the wire on the winding drum 715 onto the felt sleeve 8. At the same time, the wire is wound around the felt sleeve 8 under the drive of the rotation device 6. Then, the winding motor 712 drives the winding gear 713 to rotate, which moves the winding gear 713 along the winding rack 714. This causes the winding frame 711 to move along the axis of the mandrel 62, which in turn moves the winding head 716 along the side wall of the felt sleeve 8, thus winding the wire onto the felt sleeve 8.

[0069] Reference Figure 12 A slitting assembly 9 is detachably mounted on the winding frame 711. The slitting assembly 9 includes a slitting post 91 and a slitting blade 92. One end of the slitting post 91 is detachably mounted on the side wall of the vertical section of the winding frame 711, and the slitting blade 92 is detachably mounted on the other end of the slitting post 91. When winding is performed, the axis of the slitting post 91 is parallel to the axis of the vertical section of the winding frame 711. When the felt sleeve 8 needs to be slitted, the winding head 716 is removed from the winding frame 711, and then the slitting post 91 is rotated to a horizontal position so that the slitting blade 92 on the slitting post 91 is aligned with the felt sleeve 8. Then, the slitting blade 92 is moved towards the felt sleeve 8 by the moving mechanism 72, thereby slitting the felt sleeve 8.

[0070] The working principle of this embodiment is as follows: The main motor 221 drives the main transmission component 223 to work, causing the main transmission component 223 to drive the main lead screw 222 to rotate. This causes the main lead screw 222 to drive the lifting frame 21 to move downward, thereby causing the first needle-punching mechanism 3, the two sets of second needle-punching mechanisms 4, and the two sets of third needle-punching mechanisms 5 to descend to the felt sleeve 8. Then, the self-rotating motor 611 drives the self-rotating drive wheel 612 to rotate, causing the self-rotating drive wheel 613 to rotate, thereby driving the self-rotating drive rod 614 to rotate. This causes the self-rotating drive rod 614 to drive the spindle 62 to rotate, thereby driving the felt sleeve 8 to rotate.

[0071] Subsequently, the lifting motor 331 drives the lifting transmission component 333 to rotate, thereby causing the lifting screw 332 to rotate and thus causing the cross frame 31 to descend. Then, the lifting reciprocating component 323 drives the first needle plate 321 to move back and forth in the direction of the felt sleeve 8, thereby causing the first needle 322 on the first needle plate 321 to perform needle piercing treatment on the side wall of the felt sleeve 8.

[0072] Simultaneously, the second needle-punching mechanism 4, located at both ends of the crossbeam 31 along its length, adjusts the angle of the second needle 449 and needle-punches the rounded corners at the ends of the felt sleeve 8. The third needle-punching mechanism 5, located at both ends of the crossbeam 31 along its length, adjusts the angle of the third needle and needle-punches the curved surface at the ends of the felt sleeve 8. By using the second needle-punching mechanism 4 and the third needle-punching mechanism 5 at both ends of the crossbeam 31 along its length to needle-punch the felt sleeve 8, the efficiency of the needle-punching process for the felt sleeve 8 is improved.

[0073] After the needle punching process is completed, the main lifting mechanism 2 drives the lifting frame 21 to rise, so that the first needle 322, the second needle 449, and the third needle move away from the felt sleeve 8. Then, the moving mechanism 72 operates, so that the winding head 716 on the winding frame 711 approaches the felt sleeve 8 and guides the wire on the winding drum 715 onto the rotating felt sleeve 8, thereby winding the wire onto the felt sleeve 8. The winding motor 712 drives the winding gear 713 to rotate, so that the winding gear 713 drives the winding frame 711 to move along the winding rack 714, thereby driving the winding head 716 to move along the side wall of the felt sleeve 8, thereby evenly winding the wire onto the felt sleeve 8.

[0074] After winding is completed, the rotating winding drum 715 is braked by brake 717, and the winding head 716 is removed from the winding frame 711. Then, the slitting column 91 is rotated to a horizontal position, so that the slitting blade 92 on the slitting column 91 is aligned with the felt sleeve 8. The winding frame 711 is moved towards the felt sleeve 8 by the moving mechanism 72, thereby slitting the felt sleeve 8 into two identical felt sleeves 8. This allows for the processing of two felt sleeves 8 at once, thus improving the processing efficiency of the felt sleeves 8. After slitting, the winding frame 711 is moved away from the felt sleeve 8 by the moving mechanism 72, causing the slitting blade 92 to separate from the felt sleeve 8.

[0075] Finally, the mandrel 62 is disassembled to facilitate its transport to the next process along with the felt sleeve 8.

[0076] 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.
