Abstract
Description
Technical Field
[0001] This utility model relates to the field of microfiber nonwoven fabrics, specifically to a microfiber nonwoven fabric needle punching machine. Background Technology
[0002] Microfiber nonwoven fabric is a type of fabric formed without spinning or weaving. It consists of very fine fibers, which are typically oriented or randomly arranged to form a web structure. A microfiber nonwoven fabric needle-punching machine is a specialized device for producing microfiber nonwoven fabric. The needle-punching machine is a blanket-forming device that compacts and needle-punches a refractory fiber blanket of a certain thickness to form a refractory fiber blanket. It utilizes needles with triangular or other shaped cross-sections and barbs on the edges to repeatedly pierce the fiber web.
[0003] A search revealed a utility model of a microfiber nonwoven fabric needle punching machine, with announcement number CN216304119U, belonging to the field of needle punching machine technology. This microfiber nonwoven fabric needle punching machine includes: a machine body, with a fixed block fixedly connected to one side of the machine body, and a lower output roller rotatably connected between two fixed blocks; a protective box, fixedly connected to one side of the machine body, with three connecting rods movably inserted into the inner wall of the bottom of the protective box, and a fixed frame fixedly connected to the lower end of the three connecting rods. In this microfiber nonwoven fabric needle punching machine, when the drive motor drives the customized gear block to rotate, it causes the threaded rod to descend. The two threaded rods drive the upper output roller to the upper side of the processed nonwoven fabric. When the customized gear block rotates in the opposite direction, it causes the threaded rod to rise, and the threaded rod and connecting plate drive the fixed frame to rise. By adjusting the distance between the upper and lower output rollers, processed nonwoven fabrics of various thicknesses can be carried into the machine body, making it widely applicable.
[0004] Existing microfiber nonwoven fabric needle punching machines lack a cleaning structure for the needle heads. When the needles of the needle punching machine penetrate the microfiber nonwoven fabric, some fibers may indeed adhere to the needle surface due to the driving action of the hooks. The presence of these fibers affects the normal operation of the needle punching machine, such as increasing friction and reducing needle punching efficiency. The microfiber nonwoven fabric needle punching machine in the above comparative case also lacks a cleaning structure, thus affecting the normal operation of the needles inside the needle punching machine.
[0005] Therefore, it is necessary to invent a needle punching machine for ultrafine fiber nonwoven fabric to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a microfiber nonwoven fabric needle punching machine. By turning on the air pump switch on the upper left side of the needle punching frame, air is blown into the air pipe and multiple sets of nozzles. The multiple sets of nozzles disperse the fibers on the surface of the microfiber needles, preventing the fibers from floating everywhere. Then, turning on the fan switch generates negative pressure, which, through the dust suction pipe and dust suction hood inside the right side of the needle punching frame, adsorbs the blown fibers and collects them in the dust suction box. This not only removes dust but also cleans the fibers on the surface of the microfiber needles, thus solving the problem mentioned in the background art that existing microfiber nonwoven fabric needle punching machines lack a needle cleaning structure. When the needles of the needle punching machine penetrate the microfiber nonwoven fabric, due to the driving action of the hooks, some fibers may indeed adhere to the needle surface. The presence of these fibers affects the normal operation of the needle punching machine, such as increasing friction and reducing needle punching efficiency.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a needle punching machine for microfiber nonwoven fabric, including a needle punching worktable for needle punching microfiber nonwoven fabric;
[0008] The compaction conveying assembly is located on both sides above the needle punching worktable and is used for compaction conveying.
[0009] A needle-punching frame is fixed above the needle-punching worktable and located between the compaction and conveying components. A fixed plate is fixedly connected to the lower inner side of the needle-punching frame. A collection frame is slidably connected below the fixed plate and slidably connected to the needle-punching frame. A reciprocating guide mechanism is fixedly installed above the needle-punching frame. A telescopic plate is slidably connected inside the needle-punching frame. Ultra-fine needles are fixedly installed below each telescopic plate. A second sliding rod is slidably connected around the inner perimeter of the telescopic plate.
[0010] A cleaning mechanism, located above the needle frame, is used for vacuuming and cleaning ultra-fine needles. The cleaning mechanism includes an air pump, which is fixedly located on the left side of the needle frame. One end of the air pump is fixedly connected to an air pipe, and the other end of the air pipe is equipped with a nozzle. A fan is fixedly located on the upper right side of the needle frame. One end of the fan is fixedly connected to a dust collection box, which contains a filter screen. A suction pipe is fixedly connected to the other side of the dust collection box, and the other end of the suction pipe is fixedly connected to a dust collection hood.
[0011] Preferably, the compaction conveying assembly includes a support frame, which is disposed on both sides above the needle punching worktable. A telescopic rod is movably inserted through the inside of the support frame. A connecting frame is fixedly connected to the lower end of the telescopic rod. A spring is sleeved on the outside of the telescopic rod. First sliding rods are fixedly connected to the upper sides of the connecting frame. The first sliding rods are slidably connected to the support frame. A first pressure roller is rotatably connected inside the connecting frame. A second pressure roller is rotatably connected to the lower inner side of the support frame.
[0012] Preferably, the reciprocating guide mechanism includes a variable speed motor, which is fixed above the needle frame. A transmission rod is fixedly connected to both sides of the output end of the variable speed motor, and a rotating frame is fixedly connected to the other end of the transmission rod. A movable plate is movably sleeved inside the rotating frame, and the upper sides of the telescopic plate are hinged to the lower end of the movable plate.
[0013] Preferably, the second slide bar is provided in four sets, and the four sets of the second slide bar are symmetrically arranged about the central axis of the telescopic plate.
[0014] Preferably, the nozzle is provided in multiple sets, and the multiple sets of nozzles are located at one end of the air pipe, and the nozzles are located inside the needle frame on the left side.
[0015] Preferably, the dust suction hood is located inside the right side of the needle frame, and the nozzle is arranged parallel to the dust suction hood.
[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0017] 1. The cleaning mechanism effectively removes fibers from the surface of the ultra-fine needle head, keeping the inside of the needle frame clean and operating efficiently. When the telescopic plate and ultra-fine needle head reciprocate up and down, the air pump switch on the upper left side of the needle frame is turned on to blow air into the air pipe and multiple nozzles. The multiple nozzles disperse the fibers on the surface of the ultra-fine needle head, preventing the fibers from floating everywhere. Then, the fan switch is turned on to generate negative pressure. The fibers blown over are adsorbed into the dust collection box and collected through the dust suction pipe and dust suction hood on the right side inside the needle frame. This not only removes dust but also cleans the fibers on the surface of the ultra-fine needle head.
[0018] 2. The reciprocating guide mechanism can reciprocate to drive the telescopic plate and the ultra-fine needle head to lift and lower, and needle the surface of the ultra-fine fiber nonwoven fabric. By turning on the variable speed motor switch, the gearbox is driven to rotate. The variable speed motor drives the transmission rods on both sides and the rotating frame to rotate. The rotating frame rotates and pulls the movable plate and the telescopic plate below back and forth within the ultra-fine needle head. At the same time, during the lifting and lowering process, the telescopic plate is limited by the second slide rod inside the four sides, thereby enhancing the stability of the telescopic plate during the lifting and lowering process.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] This utility model provides, for example Figure 1-5 The microfiber nonwoven fabric needle punching machine shown includes a needle punching worktable 1 for needle punching microfiber nonwoven fabric.
[0029] The compaction conveying assembly 2 is installed on both sides above the needle punching workbench 1 for compaction conveying;
[0030] A needle frame 3 is fixed above the needle workbench 1 and located between the compaction and conveying components 2. A fixing plate 4 is fixedly connected to the lower inside of the needle frame 3. A collection frame 5 is slidably connected to the lower part of the fixing plate 4. The collection frame 5 is slidably connected to the needle frame 3. A reciprocating guide mechanism 6 is fixedly installed above the needle frame 3. A telescopic plate 7 is slidably connected inside the needle frame 3. Ultra-fine needles 8 are fixedly installed below the telescopic plate 7. A second slide rod 9 is slidably connected around the inside of the telescopic plate 7.
[0031] Cleaning mechanism 10, located above the needle frame 3, is used for vacuuming and cleaning ultra-fine needles 8. Cleaning mechanism 10 includes an air pump 1001, which is fixedly located on the left side of the needle frame 3. One end of the air pump 1001 is fixedly connected to an air pipe 1002, and the other end of the air pipe 1002 is equipped with a nozzle 1003. A fan 1004 is fixedly located on the upper right side of the needle frame 3. One end of the fan 1004 is fixedly connected to a dust collection box 1005, which contains a filter screen. The other side of the dust collection box 1005 is fixedly connected to a suction pipe 1006. The other end of 006 is fixedly connected to a dust collection hood 1007. By turning on the air pump 1001 switch on the upper left side of the needle frame 3, gas is blown into the air pipe 1002 and multiple sets of nozzles 1003. The multiple sets of nozzles 1003 are used to blow away the fibers on the surface of the ultra-fine needle head 8 to prevent the fibers from floating everywhere. Then, the fan 1004 switch is turned on to generate negative pressure. Through the dust collection pipe 1006 and the dust collection hood 1007, the blown fibers are adsorbed into the dust collection box 1005 inside the right side of the needle frame 3 and collected. This not only removes dust, but also cleans the fibers on the surface of the ultra-fine needle head 8.
[0032] like Figure 1 and Figure 2 As shown, the compaction conveying assembly 2 includes a support 201, which is positioned on both sides above the needle punching workbench 1. A telescopic rod 202 is movably inserted through the inside of the support 201. A connecting frame 203 is fixedly connected to the lower end of the telescopic rod 202, and a spring 204 is sleeved on the outside of the telescopic rod 202. First sliding rods 205 are fixedly connected to the upper sides of the connecting frame 203, and the first sliding rods 205 are slidably connected to the support 201. A first pressure roller 206 is rotatably connected inside the connecting frame 203, and a second pressure roller 207 is rotatably connected to the lower inner side of the support 201. When the microfiber nonwoven fabric passes between the first pressure roller 206 and the second pressure roller 207, it is pushed and pressed against the outside of the microfiber nonwoven fabric by the telescopic rod 202 above the first pressure roller 206 and the external spring 204, thereby enhancing the stability and compaction of the conveying.
[0033] like Figure 1 , Figure 3 and Figure 4As shown, the reciprocating guide mechanism 6 includes a variable speed motor 601, which is fixed above the needle frame 3. The output ends of the variable speed motor 601 are fixedly connected to two transmission rods 602, and the other ends of the transmission rods 602 are fixedly connected to a rotating frame 603. The rotating frame 603 is movably fitted with a movable plate 604. The upper sides of the telescopic plate 7 are hinged to the lower ends of the movable plate 604. By turning on the switch of the variable speed motor 601, the gearbox is driven to rotate. The variable speed motor 601 drives the transmission rods 602 and the rotating frame 603 on both sides to rotate. The rotating frame 603 rotates back and forth, pulling the movable plate 604 and the telescopic plate 7 below to reciprocate up and down within the ultra-fine needle head 8.
[0034] like Figure 3 and Figure 4 As shown, there are four sets of second slide rods 9. The four sets of second slide rods 9 are symmetrically arranged around the central axis of the telescopic plate 7. During the lifting and lowering process, the telescopic plate 7 is limited and slid by the second slide rods 9 inside the four sides, thereby enhancing the stability of the telescopic plate 7 during the lifting and lowering process.
[0035] like Figure 1 , Figure 3 and Figure 5 As shown, multiple sets of nozzles 1003 are provided. Multiple sets of nozzles 1003 are located at one end of the air pipe 1002. The nozzles 1003 are located inside the needle frame 3 on the left side. By turning on the air pump 1001 switch on the upper left side of the needle frame 3, gas is blown into the air pipe 1002 and multiple sets of nozzles 1003. The multiple sets of nozzles 1003 are used to blow away the fibers on the surface of the ultrafine needle tip 8.
[0036] like Figure 3 and Figure 5 As shown, the dust hood 1007 is located inside the right side of the needle frame 3. The nozzle 1003 and the dust hood 1007 are arranged parallel to each other to prevent the fibers from being blown away and floating everywhere. When the fan 1004 is turned on, a negative pressure is generated. The fibers blown by the nozzle 1003 are adsorbed into the dust collection box 1005 through the dust suction pipe 1006 and the dust hood 1007 inside the right side of the needle frame 3. This not only removes dust but also cleans the fibers on the surface of the ultra-fine needle head 8.
[0037] The working principle of this practical application is as follows: First, connect the external power supply. Then, insert the microfiber nonwoven fabric to be needled between the first pressure roller 206 and the second pressure roller 207. The telescopic rod 202 above the first pressure roller 206 and the external spring 204 push and press the microfiber nonwoven fabric, thereby enhancing the stability and compaction of the conveying process. Afterward, the nonwoven fabric enters the fixed plate 4 inside the needle-punching frame 3. At this time, turn on the variable speed motor 601 switch to drive the gearbox to rotate. The gearbox drives the transmission rods 602 on both sides and the rotating frame 603 to rotate. The rotating frame 603 rotates back and forth, pulling the movable plate 604 and the telescopic plate 7 below to reciprocate up and down within the microfiber needle head 8. At the same time, during the lifting and lowering process, the telescopic plate 7 is limited by the second sliding rod 9 inside the perimeter, thereby enhancing the stability of the telescopic plate 7 during the lifting and lowering process. At this time, the telescopic plate 7 and multiple sets of microfiber needle heads 8 reciprocate up and down, which affects the microfiber nonwoven fabric. The fabric is needle-punched using multiple sets of ultra-fine needles 8, which have a smaller diameter than traditional needles, thus forming ultra-fine fiber nonwoven fabric. During the back-and-forth movement of the multiple sets of ultra-fine needles 8, the air pump 1001 switch on the upper left side of the needle-punching frame 3 is turned on, blowing air into the air pipe 1002 and multiple sets of nozzles 1003. The multiple sets of nozzles 1003 are used to disperse the fibers on the surface of the ultra-fine needles 8, preventing the fibers from floating everywhere. Then, the blower 1004 switch is turned on to generate negative pressure, which is used to absorb the blown fibers into the dust collection box 1005 inside the needle-punching frame 3 through the dust suction pipe 1006 and dust suction hood 1007 on the right side. This not only removes dust but also cleans the fibers on the surface of the ultra-fine needles 8. Finally, the needle-punched nonwoven fabric is compacted and conveyed by the compaction and conveying component 2 on the right side. This completes the use of the ultra-fine fiber nonwoven fabric needle-punching machine.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
