Description

Technical Field

[0001] This utility model relates to the field of needle punching machine technology, specifically a non-woven needle punching machine that prevents needle breakage. Background Technology

[0002] A needle punching machine is a nonwoven fabric production equipment that uses needles to puncture a fiber web, causing the fibers to shift and compress, forming refractory fiber blankets or nonwoven fabrics. This equipment is widely used in textiles, automobile manufacturing, construction, and other fields.

[0003] During operation, when the needles inside the needle punching machine perform high-frequency piercing operations along the fabric, the fibers inside the fabric are carried out by the needles. At the same time, the airflow generated by the vibration of the mechanical parts blows the fibers. If too many fibers are lifted up, the grooves on the outer surface of the needle will become clogged, which may cause damage to the pierced parts of the fabric in severe cases.

[0004] In view of this, a non-woven fabric needle punching machine with anti-needle breakage was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A nonwoven fabric needle punching machine for preventing needle breakage includes a protective housing, a fabric needle punching mechanism installed inside the protective housing, a thread-blocking mechanism installed inside the fabric needle punching mechanism, and nonwoven fabric passing through the fabric needle punching mechanism and the thread-blocking mechanism. The fabric needle punching mechanism includes two gateposts fixedly installed on both sides of the feed end of the protective housing. The gateposts have two sliding grooves inside. Limiting rods are installed in two plate sections on the outer side of the gateposts. A bottom support plate and a beam are movably installed outside the limiting rods. The bottom support plate has multiple evenly distributed vertical holes in the middle. Multiple needles are fixedly installed inside the beam. The thread-blocking mechanism includes two pressure plates installed on the inner sides of the two gateposts. Multiple sets of symmetrically distributed thread-removing clips are fixedly installed on the top of the two pressure plates.

[0007] In a preferred embodiment, this utility model can be further configured as follows: a lever arm is movably mounted on both the base plate and the beam rod; a clamp is movably mounted inside the two lever arms; a traction plate is movably mounted on the outer end of the clamp; an eccentric wheel is movably mounted on the other end of the traction plate; a motor is mounted in the middle of the eccentric wheel; and a support plate is mounted on the outside of the motor.

[0008] In a preferred embodiment, the present invention can be further configured such that: two symmetrically distributed springs are provided on the outside of the limiting rod, and the two springs are respectively pressed on the bottom support plate and the beam rod.

[0009] In a preferred embodiment, the present invention can be further configured such that: two symmetrically distributed shafts are movably installed within two plate segments at the bottom of the pressure plate, and rotating rollers are installed on the outside of the shafts.

[0010] In a preferred embodiment, the present invention can be further configured such that an anti-slip rubber layer is installed on the outside of the roller.

[0011] In a preferred embodiment, the present invention can be further configured such that the wire clip is welded together from an elastic inclined frame and a semi-circular end, and the bottom of the semi-circular end is provided with evenly distributed conical hooks.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model has two symmetrically distributed sliding grooves inside the two gantry frames, and a bottom support plate and a beam rod are movably installed in the two sliding grooves. As the bottom support plate lifts the non-woven fabric upward, the needle fixed in the beam rod will descend at the same speed as the bottom support plate. Finally, the part of the fabric to be punctured will be stabilized and pressed. At this time, after the needle pierces into the fabric, there is no risk of damage due to the looseness and wrinkles of the fabric.

[0013] 2. This utility model sets two symmetrically distributed pressure plates between the bottom support plate and the beam, and fixes multiple sets of symmetrically distributed thread-removing clips on the top of the two pressure plates. After the needle is reset, the pointed tip of the thread-removing clip will peel off the protruding fibers, so as to avoid the fibers from rising too much and hindering the frequency vibration of the needle.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a non-woven fabric needle punching machine that prevents needle breakage.

[0019] Example 1: Combination Figures 1 to 4 As shown, the present invention provides a nonwoven fabric needle punching machine for preventing needle breakage, including a protective shell 100, a fabric needle punching mechanism 200 installed inside the protective shell 100, a thread blocking mechanism 300 installed inside the fabric needle punching mechanism 200, and a nonwoven fabric 400 inserted into the fabric needle punching mechanism 200 and the thread blocking mechanism 300. The fabric needle punching mechanism 200 is used to puncture and create holes in the nonwoven fabric 400 that is stretched at a uniform speed, and the thread blocking mechanism 300 is used to enhance the stability and protection of the nonwoven fabric 400 to be punctured.

[0020] The fabric needle punching mechanism 200 includes two gateposts 210 fixedly installed on both sides of the feed end of the protective shell 100. The gateposts 210 have two sliding grooves 2101 inside. Limiting rods 220 are installed in the two plate sections on the outside of the gateposts 210. A bottom support plate 230 and a beam rod 240 are movably installed on the outside of the limiting rods 220. The bottom support plate 230 has multiple evenly distributed vertical holes in the middle. Multiple needles 2401 are fixedly installed inside the beam rod 240. A lever arm 250 is movably installed on both the bottom support plate 230 and the beam rod 240. A clamp 2501 is movably installed in the two lever arms 250. A traction plate 2502 is movably installed at the outer end of the clamp 2501. An eccentric wheel 2602 is movably installed at the other end of the traction plate 2502. A motor 2601 is installed in the middle of the eccentric wheel 2602. A support plate 260 is installed outside the motor 2601. The wire blocking mechanism 300 includes two pressure plates 310 installed inside the two doorposts 210, and multiple sets of wire clips 320 are symmetrically distributed and fixedly installed on the top of the two pressure plates 310.

[0021] Two symmetrically distributed springs 2201 are provided on the outside of the limiting rod 220, and the two springs 2201 are respectively pressed on the bottom support plate 230 and the beam rod 240.

[0022] The motor 2601 is pre-started. As the motor 2601 runs, its internal transmission shaft, in conjunction with the eccentric wheel 2602, drives the traction plate 2502 to reciprocate and extend. The other end of the traction plate 2502 drives the clamp 2501 and the two lever arms 250 to extend in a regular manner. At this time, the bottom support plate 230 and the two pressure plates 310 stabilize and clamp the bottom and top of the uniformly stretched nonwoven fabric 400. At the moment of clamping, the descending beam 240 drives multiple needles 2401 to descend. Finally, the multiple needles 2401 will pre-pierce the pressure-bearing interior of the bottom of the nonwoven fabric 400. As the needles 2401 detach from the interior of the nonwoven fabric 400, the fibers left in the hook groove on the outer surface of the needles 2401 will be quickly stripped off by multiple sets of thread-removing clamps 320.

[0023] Example 2: Combination Figure 3 and Figure 4 As shown, in the above embodiment, two symmetrically distributed shafts 330 are movably installed in the two plate segments at the bottom of the pressure plate 310, and a rotating roller 340 is installed on the outside of the shafts 330. The outside of the roller 340 is fitted with an anti-slip rubber layer; The wire clip 320 is made of a flexible inclined frame and a semi-circular end welded together, and the bottom of the semi-circular end is provided with evenly distributed tapered hooks.

[0024] Preferably, the lower surface of the pressure plate 310 is rough, and the shaft 330 is installed in the bottom section of the pressure plate 310 through bearings. The two adjacent sets of rotating rollers 340 are used to tighten the nonwoven fabric 400 at both ends in the middle part, so as to ensure that after the bottom support plate 230 rises and adheres to the nonwoven fabric 400, the pressure part of the nonwoven fabric 400 will not have local wrinkles or loosening problems, and to ensure that multiple needles 2401 can quickly penetrate into the interior of the tightened nonwoven fabric 400.

[0025] The working principle and usage process of this utility model are as follows: The non-woven fabric 400 is inserted into the gap between two of the rotating rollers 340 in advance until the non-woven fabric 400 is pulled and stretched at a constant speed along the inner side of the two sets of rotating rollers 340. Next, the motor 2601 is started and run until it drives the eccentric wheel 2602 to rotate. The traction plate 2502 will extend eccentrically along the eccentric wheel 2602, and the other end of the traction plate 2502 will pull the clamp 2501 and the two lever arms 250 to extend relative to each other. The two lever arms 250 will drive the base plate 230 and the beam 240 to extend in a regular reciprocating motion. The multiple needles 2401 fixed inside the beam 240 will extend downward along the gaps of the multiple sets of thread release clips 320. Finally, the needles 240... The needle 2401 extends along the gap between the two pressure plates 310 and pierces into the interior of the nonwoven fabric 400. At the same time, the bottom support plate 230 rises in sync with the needles 2401. The bottom of the nonwoven fabric 400 to be pierced is pressed and adheres to the lower surface of the two pressure plates 310. Finally, after the needles 2401 pierce into the interior of the nonwoven fabric 400 and detach, the evenly distributed sets of thread release clips 320 will release the residual threads in the needles 2401, thereby avoiding the problem of the threads obstructing the piercing operation of the needles 2401.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
