Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a needle punching device for nonwoven fabric processing. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber and is produced through a needle-punching process. This allows for the creation of different thicknesses, textures, and hardnesses. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxicity, odorlessness, low price, and recyclability, making them suitable for various industries. Current technology requires the use of needle-punching devices in the processing of non-woven fabrics. The needle-punching process involves repeatedly piercing the fiber web with needles, causing the fibers to entangle and thus increasing the material's strength. A search revealed that application number 202223233518.9 discloses a needle-punching device for processing needle-punched nonwoven fabrics, including a base plate and a clamping assembly; the base plate has a winding assembly installed on its upper left side; the clamping assembly includes a fixed frame, a first electric telescopic rod, a movable plate, a fixed frame, and a clamping frame. The fixed frame is fixed to the upper side of the base plate, the first electric telescopic rod is installed on the upper side of the fixed frame, the movable plate is fixed to the telescopic arm of the first electric telescopic rod, the clamping frame is fixed to the front side of the movable plate, and the fixed frame is fixed to the lower front side of the fixed frame. The fixed frame and the clamping frame correspond to each other. The movable assembly is installed on the upper side of the fixed frame, and the needle-punching assembly is installed on the movable assembly.

[0003] However, this device only uses the first electric telescopic rod on one side of the fixed frame to move, clamp, and fix the nonwoven fabric, which reduces the fixing effect of the nonwoven fabric on the other side and affects the subsequent needle-punching process of the nonwoven fabric. At the same time, by setting up another second electric telescopic rod to achieve the needle-punching effect on the nonwoven fabric, the equipment cost is greatly increased.

[0004] Therefore, we propose a needle punching device for nonwoven fabric processing. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a needle punching device for nonwoven fabric processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a needle punching device for nonwoven fabric processing, comprising a mounting base plate, a first mounting frame fixedly mounted on the top left side of the mounting base plate, and a second mounting frame fixedly mounted on the top right side of the mounting base plate. A pressing clamping mechanism is provided on the inner wall of the first mounting frame, and the right side of the outer wall of the pressing clamping mechanism is movably connected to the inner wall of the second mounting frame. A rolling needle punching mechanism is provided on the inner wall of the pressing clamping mechanism.

[0007] Preferably, a mounting frame is fixedly installed on the right side wall of the first slider, and a second slider is fixedly installed on the right side wall of the mounting frame, with the outer wall of the second slider being movably connected to the inner wall of the second mounting bracket.

[0008] Preferably, a reciprocating lead screw is fixedly installed at the output end of the second servo motor, and the front side of the reciprocating lead screw is movably connected to the front end of the inner wall of the mounting frame.

[0009] Preferably, a first limiting guide rod is movably installed on the inner wall of the second slider, and the top and bottom of the first limiting guide rod are fixedly connected to the top and bottom of the inner wall of the second mounting frame, respectively.

[0015] This invention provides a needle punching device for nonwoven fabric processing. It has the following beneficial effects:

[0016] 1. The needle punching device for nonwoven fabric processing is equipped with a downward clamping mechanism. The downward clamping mechanism can drive the mounting frame and the elastic clamping and resetting assembly to move downward stably through the first lead screw and the first limit guide rod. This allows the elastic clamping and resetting assembly to stably clamp and fix the nonwoven fabric, preventing the nonwoven fabric from loosening. At the same time, the compression spring, limit frame and clamping frame plate on the elastic clamping and resetting assembly can clamp the nonwoven fabric without affecting the piercing of the nonwoven fabric by the needle punching roller on the rolling needle punching mechanism. There is no need to set up an additional electric telescopic rod to achieve the piercing purpose, which greatly reduces the equipment cost.

The needle punching device for nonwoven fabric processing, by setting a first slider and a second slider, can further limit the mounting frame, making the mounting frame and the elastic clamping and resetting assembly more stable during the lifting and clamping process, and further improving the overall device's clamping and fixing effect on nonwoven fabric.

The clamping frame plate 24 clamps and fixes the non-woven fabric on the mounting base plate 10. The mounting frame 18 drives the needle-punching roller 2 on the rolling needle-punching mechanism 14. 9. The compression spring 22 continues to move downward to puncture the nonwoven fabric. By turning on the switch of the second servo motor 25, the output end of the second servo motor 25 drives the reciprocating screw 26 to start rotating. The reciprocating screw 26 drives the third slider 27 to move back and forth. The third slider 27 drives the fourth slider 30 to move back and forth along the second limit guide rod 31 through the third mounting frame 28. The third mounting frame 28 drives the needle-punching roller 29 to move back and forth on the nonwoven fabric to repeatedly puncture the fiber web on the nonwoven fabric, so that the fibers entangle to enhance the material strength of the nonwoven fabric.
