Description

Technical Field

[0001] The present invention belongs to the technical field of needle punching machines, and relates to a cylindrical needle punching machine, in particular to a carbon fiber cylindrical needle punching machine. Background Art

[0002] A needle punching machine is a machine for forming a refractory fiber blanket by compacting and needle punching a refractory fiber blanket blank of a certain thickness. A needle with a triangular or other shaped cross-section and barbs on the edges is used to repeatedly puncture the fiber web. The fiber web discharged from a cross-laying or air-laying machine is very fluffy when fed into the needle punching machine. It only has a certain strength due to the cohesion between fibers, but the strength is very poor. When multiple needles puncture the fiber web, the barbs on the needles will drive the fibers on the surface and subsurface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down exert a certain pressure on the fiber web, causing the fibers in the fiber web to come closer and be compressed.

[0003] After retrieval, as disclosed in a Chinese patent document for a carbon fiber cylindrical needle punching machine [Application No.: CN202321007744.7; Publication No.: CN220057241U]. This carbon fiber cylindrical needle punching machine includes a machine body. A workbench and a mounting frame are arranged in the inner cavity of the machine body. A needle plate is slidably connected in the inner cavity of the mounting frame. A driving assembly is arranged in the inner cavity of the machine body. Two limiting columns are respectively slidably connected with two through grooves at the top of the mounting frame, and the bottom ends of the two limiting columns are respectively slidably connected with two sliding grooves at the top of the needle plate.

[0004] Although the carbon fiber cylindrical needle punching machine disclosed in this patent facilitates the replacement of the needle plate by changing the fixing method of the needle plate, however, the direct replacement and maintenance cost of the needle plate is relatively high, and the needle punching machine needs to be shut down for operation, increasing the production cost. Moreover, the current needle punching machine can only perform single-sided needle punching effect, and the needle punching effect on relatively thick carbon fiber materials is limited, and it is easy to cause the needle to break, affecting the service life of the needle, so that the applicable range of the needle punching machine is limited and the practicability is poor. Summary of the Invention

The technical problem to be solved by this invention is: how to achieve efficient needle punching of relatively thick carbon fibers, and achieve convenient maintenance of the needles, save production costs, and improve production efficiency.

The incomplete gear is located outside the frame; Needle punching assemblies are arranged to be lifted and lowered inside both cylindrical bodies. And the two needle punching assemblies are symmetrically distributed up and down inside the two cylindrical bodies. And a dust suction and cleaning assembly is further provided outside the needle punching assembly. The two dust suction and cleaning assemblies are symmetrically arranged with respect to the inner top wall and inner bottom wall of the two cylindrical bodies; The needle punching assembly includes a rack. The rack is meshed with the outer wall of the incomplete gear. And the rack is located outside the frame. A cross plate is fixedly connected to the bottom end of the rack. A suspension rod is fixedly connected between the two cross plates. An installation frame is fixedly installed below the suspension rod. A plurality of needle points are fixedly connected to the bottom end of the installation frame. The needle points are movably inserted into the through holes below the cylindrical body. Air ducts are connected between the through holes inside the cylindrical body. An air outlet fan is connected to the outside of the air duct.

[0007] The working principle of the present invention is as follows: Carbon fiber is fed between two cylindrical bodies through guide rollers and tension rollers inside the frame. When the driving motor is powered on, the driving rod drives the gear disc to rotate. Through the meshing connection between the gear disc and the gear ring, the two meshing gear rings rotate relative to each other, facilitating the feeding of carbon fiber by the upper and lower cylindrical bodies. Moreover, through the action of the first meshing belt, the second meshing belt, and the third meshing belt, the tension roller, the guide roller, the receiving roller, and the winding roller can supply and receive materials synchronously through the rotation of the driving rod, realizing the integration of the carbon fiber needling process. At the same time, by drivingly connecting a transmission rod to one side of the gear disc and fixedly installing an incomplete gear at the end of the transmission rod, the incomplete gear drives the rack on its outer wall to move. Moreover, by sleeving a support spring on the outer wall of the incomplete gear, the rack drives the cross plate to move up and down inside the cylindrical body. By symmetrically arranging two needling assemblies inside the two cylindrical bodies, when the needle penetrates and is inserted into the through hole, by arranging a dust removal plate between the cylindrical body and the mounting frame, when the two cylindrical bodies rotate towards each other to drive the carbon fiber to be conveyed, the mounting frame drives the needle to move up and down, so that the needle needles the carbon fiber between the two cylindrical bodies through the dust removal plate. At the same time, through the corresponding arrangement of the dust removal plate, the through hole, and the needle, the dust removal plate can scrape the broken fibers on the outer wall of the needle, avoiding needle contamination, so that the impurities on the outer wall of the needle are retained inside the cylindrical body through the through hole. Moreover, by arranging an air duct inside the cylindrical body, the air outlet of the air duct blows up the impurities inside the cylindrical body, avoiding the impurities falling to the bottom inside the cylindrical body and affecting the operation of the needle. At the same time, under the rotation of the cylindrical body, the cylindrical body can also rotate so that the through holes at different positions clean the needle, further improving the needling quality of the needle.

Through the setting of the gear plate, the two incomplete gears 14 below can rotate synchronously, realizing the rotation synchronization of the upper and lower incomplete gears 14, making it convenient for the incomplete gear 14 to drive the needle 19 through the rack 15 on the outer wall to perform efficient synchronous needling treatment inside the two cylindrical bodies 5, achieving efficient needling effect on thicker carbon fibers, and improving processing efficiency. Among them, two incomplete gears 14 are symmetrically arranged about the central axis of the cylindrical body 5. The incomplete gears 14 on both sides of the upper cylindrical body 5 respectively drive the tension roller 3 and the winding roller 4, and the upper cylindrical body 5 The outer walls of the incomplete gears 14 on both sides are fixedly connected to the first meshing wheels 33, and the outer walls of the first meshing wheels 33 are meshedly connected to the first meshing belts 34, wherein the inner wall of the bottom end of one of the first meshing belts 34 is transmission-connected to the tension roller 3, and the inner wall of the bottom end of the other first meshing belt 34 is transmission-connected to the winding roller 4.

At the same time, a receiving roller 35 is provided below the winding roller 4. By providing the receiving roller 35 below the winding roller 4, the receiving roller 35 can well receive the carbon fiber on one side of the two cylinders 5, which is convenient for the winding roller 4 to efficiently wind up the carbon fiber, which is beneficial to improving the winding flatness of the carbon fiber. Specifically, the receiving roller 35 is rotatably connected to the inside of the frame 1, and the receiving roller 35 is located on one side of the cylinder 5. The incomplete gears 14 on both sides of the lower cylinder 5 respectively transmit the guide roller 2 and the receiving roller 35, and the outer wall of the receiving roller 35 is fixedly connected to the second meshing wheel 3 6.

The structure is simple and the driving cost is low, which is convenient for later maintenance.

[0037] Working principle of the present invention: During use, carbon fiber is fed between two cylindrical bodies 5 through a guiding roller 2 and a tension roller 3 inside a frame 1. Under the action of energizing a driving motor 9, a driving rod 8 drives a gear disk 7 to rotate. Through the meshing connection between the gear disk 7 and a gear ring 6, the two mutually meshing upper and lower gear rings 6 rotate relative to each other, facilitating the upper and lower cylindrical bodies 5 to convey the carbon fiber. Moreover, through the action of a first meshing belt 34, a second meshing belt 37, and a third meshing belt 39, the tension roller 3, the guiding roller 2, a material receiving roller 35, and a winding roller 4 can supply and receive materials synchronously through the rotation of the driving rod 8, realizing the integration of carbon fiber needling treatment. At the same time, by drivingly connecting a transmission rod 13 to one side of the gear disk 7 and fixedly installing an incomplete gear 14 at the end of the transmission rod 13, the incomplete gear 14 drives a rack 15 on its outer wall to move. Moreover, by sleeving a support spring 20 on the outer wall of the incomplete gear 14, the rack 15 drives a cross plate 16 to move up and down inside the cylindrical body 5. By symmetrically arranging two needling assemblies inside the two cylindrical bodies 5 and with a needle 19 inserted through a through hole, by arranging a dust removal plate 45 between the cylindrical body 5 and a mounting frame 18, when the two cylindrical bodies 5 rotate towards each other to drive the carbon fiber to be conveyed, the mounting frame 18 drives the needle 19 to move up and down, so that the needle 19 needles the carbon fiber between the two cylindrical bodies 5 through the dust removal plate 45. At the same time, through the corresponding arrangement of the dust removal plate 45, the through hole, and the needle 19, the dust removal plate 45 can scrape the broken fibers on the outer wall of the needle 19, avoiding the contamination of the needle 19, so that the impurities on the outer wall of the needle 19 are retained inside the cylindrical body 5 through the through hole. Moreover, by arranging an air duct 46 inside the cylindrical body 5, the air outlet of the air duct 46 blows up the impurities inside the cylindrical body 5, avoiding the impurities falling to the bottom inside the cylindrical body 5 and affecting the operation of the needle 19. At the same time, under the rotation of the cylindrical body 5, the cylindrical body 5 can also rotate to clean the needle 19 through through holes at different positions, further improving the needling quality of the needle 19. At the same time, by arranging a dust suction and cleaning assembly inside the cylindrical body 5, under the action of an "X"-shaped first movable plate 25 and a second movable plate 27, an adjusting block 29 can drive a cleaning sponge 31 to expand and contract, facilitating the cleaning sponge 31 to fit and clean the inner wall of the cylindrical body 5, realizing the maintenance effect on the inner wall of the cylindrical body 5, facilitating the stable cleaning of the needle 19 by the cylindrical body 5 during the conveying and needling process, reducing the maintenance cost of the needle 19. Moreover, through the arrangement of a dust collection pipe 41, it is convenient for the impurities inside the cylindrical body 5 to enter the inside of a dust collection box 42. And under the action of rotatably connecting a plurality of partition plates 44 inside the dust collection box 42, the dust collection box 42 can continuously suck dust, realizing the non-stop cleaning inside the dust collection box 42. Just like this, the working principle of this carbon fiber cylindrical needling machine is completed.

[0038] In summary, in the present invention, through the symmetric arrangement of the two cylindrical bodies 5 and the symmetric arrangement of the two needle punching components, the two needle punching components can efficiently punch the carbon fiber up and down, facilitating the efficient and stable needle punching process of the carbon fiber. Moreover, by telescopically arranging the needle 19 inside the cylindrical body 5, under the rotation of the cylindrical body 5 and the telescopic action of the needle 19, the needle 19 can punch through the through hole. And by arranging the dust removal plate 45 between the cylindrical body 5 and the mounting frame 18, the dust removal plate 45 can scrape the broken fibers on the outer wall of the needle 19, limiting and retaining the impurities on the surface of the needle 19 inside the cylindrical body 5, avoiding the contamination of the needle 19, realizing the maintenance of the needle 19, enabling the needle 19 to be cleaned and maintained during the needle punching process. Furthermore, by arranging the dust suction and cleaning component inside the cylindrical body 5, the impurities of the needle 19 remaining on the inner wall of the cylindrical body 5 through the dust removal plate 45 are effectively cleaned. Compared with the existing method of replacing the entire needle plate, the maintenance cost is lower, and the synchronous treatment of the needle 19 during the needle punching process of the needle punching machine is realized, ensuring the needle punching quality and efficiency, and solving the technical problems that the current carbon fiber cylindrical needle punching machine cannot efficiently punch thick carbon fiber, the maintenance of the needle 19 is inconvenient, and the production cost is high.
