[0038] The following combines the attached Figure 1-14 The present invention will be further described in detail.

[0039] Embodiment 1

[0040] As Figure 1 - Figure 14 shown, a cylindrical needle punching machine with an on-line cutting function includes a frame 1;

[0041] A cylindrical core mold mechanism 2, installed on the frame 1, for winding the coil to be needle punched and driving the coil to rotate;

[0042] A needle punching mechanism 3, installed on the frame 1, for needle punching the coil on the cylindrical core mold mechanism 2;

[0043] A yarn feeding rack mechanism 4, installed on the frame 1 and located on one side of the cylindrical core mold mechanism 2, for unwinding the coil to be needle punched to the cylindrical core mold mechanism 2;

[0044] A cutting mechanism 5, installed on the frame 1, for cutting and trimming the coil on the cylindrical core mold mechanism 2.

[0045] The working principle and beneficial effects of the above technical solution are:

[0046] A cylindrical needle punching machine with an online cutting function according to the present invention, when processing a coil material, winds the coil material to be needle punched on the cylindrical core mold mechanism 2, facilitating the needle punching process by the needle punching mechanism 3. Inside the present invention, a yarn rack mechanism 4 is provided, and a tensioning device is provided inside the yarn rack mechanism 4 to evenly unwind the coil material onto the cylindrical core mold mechanism 2. During the needle punching process, the cylindrical core mold mechanism 2 can intermittently drive the coil material to rotate, and the needle punching mechanism 3 performs needle punching on different positions of the coil material. After the needle punching is completed, the cutting mechanism 5 can be controlled to perform cutting and trimming on the coil material on the cylindrical core mold mechanism 2. The cutting mechanism 5 can not only effectively cut off the rough parts at both ends of the coil material, improving the finished product quality of the processed product; but also cut both ends of the coil material to trim it to a preset length, eliminating the need for subsequent separate processing and improving production efficiency.

[0047] The cutting mechanism 5 includes a cutting tool assembly; the cutting tool assembly is installed on a longitudinal displacement assembly to adjust its longitudinal position under the control of the longitudinal displacement assembly; the longitudinal displacement assembly is installed on a transverse displacement assembly to adjust the transverse positions of the longitudinal displacement assembly and the cutting tool assembly under the control of the transverse displacement assembly; the transverse displacement assembly is installed on the frame 1.

[0048] The transverse displacement assembly is installed on the frame 1. The transverse displacement assembly can drive the longitudinal displacement assembly and the cutting tool assembly to adjust the transverse position, so that the cutting tool assembly moves above the part to be cut; the longitudinal displacement assembly can drive the cutting tool assembly to adjust the longitudinal position, so that the cutting tool assembly reaching the preset position moves towards the coil material to be cut and contacts the coil material to be cut, so as to realize the cutting of the coil material when the cylindrical core mold mechanism 2 drives the coil material to rotate.

[0049] The cutting tool assembly includes a tool body 6 and a tool holder 7 for installing the tool body 6. The tool holder 7 is installed on the longitudinal displacement assembly. The tool body 6 is a replaceable tool structure, facilitating maintenance and repair.

[0050] The longitudinal displacement assembly includes a lifting seat 8. The lifting seat 8 is fixed to the lower end of a guiding vertical shaft 9. The middle part of the guiding vertical shaft 9 slides on a connecting seat 10. The connecting seat 10 is connected to the transverse displacement assembly. A vertical sliding frame 11 is fixed on the lifting seat 8. The middle part of the vertical sliding frame 11 slides on the connecting seat 10. A lifting driving motor 12 is installed on the top of the vertical sliding frame 11. The output shaft of the lifting driving motor 12 is connected to the upper end of a vertical lead screw 13. The middle part of the vertical lead screw 13 is threadedly connected to the connecting seat 10. The lower end of the vertical lead screw 13 is rotatably connected to the lifting seat 8.

[0051] The lifting driving motor 12 drives the vertical lead screw 13 to rotate. The rotation of the vertical lead screw 13 changes its connection position with the connecting seat 10, driving the lifting seat 8 to move up and down. When the lifting seat 8 moves, it drives the guiding vertical shaft 9 to slide on the connecting seat 10, and is guided and limited by the guiding vertical shaft 9.

[0052] A limiting block is fixed to the upper end of the guiding vertical shaft 9 to prevent the guiding vertical shaft 9 from separating from the cigarette attaching base 10.

[0053] There are two guiding vertical shafts 9, which are located on both sides of the vertical sliding carriage 11, improving the stability of the movement of the lifting seat 8.

[0054] The lateral displacement assembly includes a lateral support 14, which is installed on the frame 1; two lateral guide rails 15 are arranged side by side on the lateral support 14, and guide rail sliders are slidably connected to both of the two lateral guide rails 15. A plurality of guide rail sliders are all fixed to the lateral sliding seat 16, and the lateral sliding seat 16 is connected to the cigarette attaching base 10; both ends of the lateral support 14 are rotatably connected to synchronous pulleys 17, and one synchronous pulley 17 is connected to the output end of a lateral driving motor 18 installed on the lateral support 14; the two synchronous pulleys 17 are drivingly connected by a synchronous belt 19; the lateral sliding seat 16 is fixed to the synchronous belt 19.

[0055] The lateral driving motor 18 drives one synchronous pulley 17 connected thereto to rotate. When this synchronous pulley 17 rotates, it drives the other synchronous pulley 17 to rotate through the synchronous belt 19. During the rotation of the two synchronous pulleys 17, the synchronous belt 19 is driven to perform a surrounding movement. When the synchronous belt 19 moves, it drives the lateral sliding seat 16 to perform a lateral movement. The lateral sliding seat 16 drives a plurality of guide rail sliders to slide on the two lateral guide rails 15, realizing the adjustment of the lateral position of the cutting tool assembly.

[0056] The synchronous belt 19 is located between the two lateral guide rails 15, so that when the synchronous belt 19 drives the lateral sliding seat 16, the forces on both sides of the lateral sliding seat 16 are uniform, improving the stability of the lateral movement of the cutting tool assembly.

[0057] Embodiment 2

[0058] As Figure 1 - Figure 14 shown, the tool holder 7 includes a tool storage rack 20. The top of the tool storage rack 20 is connected to the longitudinal displacement assembly. An insertion opening is provided at the bottom of the tool storage rack 20. The middle part of the tool body 6 is slidably fitted in the insertion opening. The upper end of the tool body 6 is connected to a telescopic driving part installed on the tool storage rack 20 to slide out or slide into the insertion opening under the drive of the telescopic driving part. After controlling the tool body 6 to slide out below the insertion opening, the coil material can be cut by the tool body 6. After controlling the tool body 6 to slide into the insertion opening, it can prevent the tool body 6 from accidentally injuring the operating worker, and can also provide a certain degree of protection for the cutting edge of the tool body 6, avoiding corrosion and other conditions caused by its long-term exposure to the air, and ensuring its cutting performance.

[0059] The telescopic driving part includes a T-shaped slider 21. The upper end of the tool body 6 is connected to the T-shaped slider 21. Both ends of the T-shaped slider 21 are slidably connected to the side slideways on both sides of the tool storage rack 20. One end of the T-shaped slider 21 is rotatably connected to one end of a push-pull connecting rod 22, and the other end of the push-pull connecting rod 22 is rotatably connected to an eccentric position of a rotating disk 23. The rotating disk 23 is fixed on a rotating shaft 24. The rotating shaft 24 is rotatably connected to the tool storage rack 20. A worm gear fixed on the rotating shaft 24 meshes with a worm 25 rotatably connected to the tool storage rack 20.

[0060] One end of the worm 25 is provided with a hexagonal groove, and it can be screwed by a hexagonal screw for manual control. The other end of the worm 25 is connected to a motor through a coupling, so that it can rotate under the control of the motor. When the worm 25 rotates, it can drive the worm gear to rotate. When the worm gear rotates, it can drive the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, it can drive the rotating disk 23 to rotate, thereby driving one end of the push-pull connecting rod 22 to perform a circular motion. The other end of the push-pull connecting rod 22 drives the T-shaped slider 21 to slide in the up-and-down direction in the side slideways on both sides of the tool storage rack 20. Two sliding plates are limited on the T-shaped slider 21, and the two sliding plates slide relatively on the two side surfaces inside the tool storage rack 20 to prevent the T-shaped slider 21 from shifting when sliding. When the T-shaped slider 21 slides, it drives the tool body 6 to slide out or into the insertion opening. Through the setting of the worm 25 and the worm gear, it is in a relatively locked state after adjustment and will not loosen easily.

[0061] The tool holder 7 further includes a grinding part 26 and an oiling part 27 installed on the tool storage rack 20. The grinding part 26 is provided with a grinding groove that slidably cooperates with the cutting edge of the tool body 6, and a grindstone is provided on the inner side surface of the grinding groove. There are two oiling parts 27, and the two oiling parts 27 are oppositely arranged on both sides of the tool body 6 to perform oiling treatment on both sides of the tool body 6.

[0062] When the tool body 6 slides out or into the insertion opening under the control of the telescopic driving part, the cutting edge of the tool body 6 contacts the grindstone in the grinding groove of the grinding part 26. The cutting edge of the tool body 6 can be polished by the grindstone each time it is used, improving the sharpness of the cutting edge of the tool body 6. When the present invention is not in use, the reciprocating sliding movement of the tool body 6 in the up and down direction can also be controlled through the structural settings of the tool holder 7 and the tool body 6, so as to perform a more delicate polishing and grinding treatment on the cutting edge of the tool body 6, and regularly grind to improve its cutting effect; and when the tool body 6 performs the reciprocating sliding movement in the up and down direction, its different positions contact the two oiling parts 27, and the two oiling parts 27 can perform oiling treatment on both sides of the tool body 6. The setting of this structure can not only cooperate with the grindstone to grind the tool body 6, improving the grinding effect, but also prevent oxidation and rust of the tool body 6 through oiling maintenance, and can improve its cutting effect during cutting, preventing jamming. Moreover, this oiling treatment does not require manual operation and can rely on the control of the telescopic driving part.

[0063] The grinding part 26 includes a grinding rack 28 provided with a grinding groove. The middle part of the grinding rack 28 slides in the horizontal slideway on the side of the tool storage rack 20. Two stoppers 29 are fixed on the side of the grinding rack 28. One ends of two cross bars 30 are fixedly connected with the two stoppers 29. The middle parts of the two cross bars 30 slide in the horizontal round holes on the side of the tool storage rack 20. The other ends of the two cross bars 30 are both fixed with limit blocks. The stoppers 29 and the limit blocks are located inside and outside the tool storage rack 20 respectively; A tension compression spring 31 is sleeved on the rod body of each cross bar 30 between the stopper 29 and the tool storage rack 20. Under the elastic force of the tension compression spring 31, the grinding rack 28 keeps pressing against the cutting edge of the tool body 6, improving the grinding effect and ensuring the tightness of the contact.

[0064] An adjusting nut is rotatably connected to the cross bar 30. The adjusting nut is located between the tool storage rack 20 and the limit block. By rotating the adjusting nut, the length of the cross bar 30 inserted into the inside of the tool storage rack 20 can be changed. At this time, the contact or separation between the grinding rack 28 and the cutting edge of the tool body 6 can be controlled, and whether to perform grinding treatment can be selected according to the actual situation of the cutting edge of the tool body 6.

[0065] The oiling part 27 includes an oiling wheel 32. The oiling cloth layer of the oiling wheel 32 is attached to the side surface of the tool body 6. The oiling wheel 32 is fixed on a transverse wheel shaft 33. The transverse wheel shaft 33 is rotatably connected to the tool storage rack 20. The lower end of the oiling wheel 32 is in rolling fit with the arc-shaped groove at the top of the oil storage tank 34. The oil storage tank 34 is fixed on the tool storage rack 20. A rotary oil supply wheel 35 is rotatably connected inside the oil storage tank 34. The oil absorption cotton layer wrapped on the rotary oil supply wheel 35 is attached to the wheel surface of the oiling wheel 32. A plurality of longitudinal oil guiding cotton strips 36 are fixed on the inner wall of the oil storage tank 34. The lower ends of the plurality of longitudinal oil guiding cotton strips 36 abut against the inner bottom surface of the oil storage tank 34, and the upper ends of the longitudinal oil guiding cotton strips 36 are attached to the oil absorption cotton layer of the rotary oil supply wheel 35.

[0066] When the tool body 6 moves up and down, the oiling cloth layer of the oiling wheel 32 contacts different positions on the side surface of the tool body 6. When different positions on the wheel surface of the oiling wheel 32 rotate to contact the arc-shaped groove of the oil storage tank 34, oil liquid is transferred to the oiling cloth layer on the oiling wheel 32, and the oil liquid absorbed by the oiling cloth layer of the oiling wheel 32 is used to oil the side surface of the tool body 6. A plurality of longitudinal oil guiding cotton strips 36 are fixed on the inner wall of the oil storage tank 34. The lower ends of the plurality of longitudinal oil guiding cotton strips 36 abut against the inner bottom surface of the oil storage tank 34, and the upper ends of the longitudinal oil guiding cotton strips 36 are attached to the oil absorption cotton layer of the rotary oil supply wheel 35. Thus, after the oil liquid wets the longitudinal oil guiding cotton strips 36, the oil liquid can be guided to the oil absorption cotton layer through the longitudinal oil guiding cotton strips 36, preventing the oil absorption cotton layer of the rotary oil supply wheel 35 from being unable to adsorb oil liquid when the liquid level of the oil liquid in the oil storage tank 34 is relatively low.

[0067] One end of the transverse wheel shaft 33 is fixed with a linkage gear 37, and the linkage gears 37 of the two oiling parts 27 are meshed and connected.

[0068] A linkage pulley 38 is fixed on one transverse wheel shaft 33. The linkage pulley 38 is connected to a transmission pulley 39 through a synchronous belt. The transmission pulley 39 is fixed on a short shaft. The short shaft is rotatably connected to the tool storage rack 20. A driven gear 40 is fixed on the short shaft. The driven gear 40 is meshed with a vertical rack 41. The vertical rack 41 is fixed on the side part of the T-shaped slider 21.

[0069] When the vertical rack 41 moves up and down, it can drive the driven gear 40 to rotate. When the driven gear 40 rotates, it can drive the short shaft to rotate, thereby driving the linkage pulley 38 to rotate through the transmission pulley 39 on the short shaft, so as to drive one transverse wheel shaft 33 to rotate. When this transverse wheel shaft 33 rotates, through the meshing of the two linkage gears 37, the two transverse wheel shafts 33 are driven to rotate, thereby driving the two oiling wheels 32 to rotate.

[0070] On one or both sides of the tool body 6, there is an oil guide groove inclined towards the cutting edge of the tool body 6. The horizontal height of the end of the oil guide groove close to the cutting edge of the tool body 6 is lower than the horizontal height of the end of the oil guide groove far from the cutting edge of the tool body 6. The setting of this oil guide groove is to make the oil liquid coated on the side of the tool body 6 flow towards the cutting edge of the tool body 6, so that the cutting edge of the tool body 6 can also be effectively lubricated.

[0071] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral one; it may be a mechanical connection, an electrical connection or communication with each other; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
