Technical Field

[0001] The utility model relates to the technical field of needle punching machines, and particularly relates to a needle punching machine with a needle protection structure. Background Technique

[0002] Needle punching machines are widely used in high-temperature filtration products. The high-performance fibers of high-temperature filtration products mainly include glass fiber, Nomex fiber, P84 fiber, PPS fiber, and PETT fiber. Due to the characteristics of the first few fibers, their application ranges are affected to a certain extent. Glass fiber is relatively brittle, Nomex fiber has poor oxidation resistance, P84 fiber is prone to hydrolysis and aging, and PPS fiber has a relatively low service temperature. While PETT fiber is resistant to chemical corrosion and high temperature, can be used in various harsh environments and achieve good results, and also has a longer service life than filter materials made of other fibers.

[0003] After retrieval, the existing Chinese patent publication number is: CN 220520780 U, which provides a needle punching machine. The patent collects the fibers falling on the supporting mesh plate by arranging a collecting device below the supporting mesh plate, effectively avoiding the phenomenon that the fibers fall into the machine interior and affect the normal operation of the machine after long-term accumulation. By opening the operation door, the pulling out and retracting of the collecting device are realized through the connecting component, and the structure is simple and the operation is convenient.

[0004] Although the above patent can collect the fibers falling on the supporting mesh plate and effectively avoid the fibers falling into the machine interior, the above needle punching machine still has the following problems: it cannot well retract and protect the needles, and thus it is easy to cause the phenomenon that maintenance personnel are pricked during maintenance or the needles are damaged by external impacts.

[0005] In view of the above problems, a needle punching machine with a needle protection structure is proposed. Content of the Utility Model

Both extrusion plates are slidably connected inside the frame. Two sliding channels are opened inside the frame. Moving rods are slidably connected inside both sliding channels. Protection rods are fixedly installed at the bottoms of both moving rods. Limit guide rods are fixedly installed inside both sliding channels. The two limit guide rods are respectively slidably connected inside the two moving rods. Elastic springs are movably sleeved on both limit guide rods. One end of the two elastic springs facing each other is fixedly connected to the two moving rods respectively. The other end of the two elastic springs facing away from each other is fixedly connected to the inside of the two sliding channels respectively.

[0008] Preferably, the bottoms of both extrusion plates are triangular.

[0009] Preferably, four fixing rods are fixedly installed inside the protection box. Connecting pieces are slidably connected to all four fixing rods.

[0010] Preferably, a needle plate is fixedly installed on the four connecting pieces. A needle is fixedly installed at the bottom of the needle plate. A circular hole is opened at the bottom of the protection box. The circular hole is in line with the needle.

[0032] When the protective box 4 moves downward, the pulley 17 will no longer pull the connecting drawstring 8, so the connecting drawstring 8 will no longer pull the needle plate 12. The needle plate 12 will reset by the elastic force of the spring 15, and then the needle 16 will move downward, and the needle 16 will pass through the inside of the circular hole 18. When the protective box 4 moves upward, the pulley 17 pulls the connecting drawstring 8, and then the connecting drawstring 8 pulls the needle plate 12, and then the needle plate 12 moves upward, retracting the needle 16 into the inside of the protective box 4, which is convenient for protecting the needle 16.
