Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric processing, in particular to a raw material conveying device for non-woven fabric processing. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are made of polyester fiber and polyester fiber materials. They are made through a needle-punching process and can be made into different thicknesses, feels, hardness, etc. In the production of non-woven fabrics, polypropylene particles need to be transported to a processing container for heating and melting, and then the molten polypropylene is extruded into filaments through a spinning device. These filaments are then cooled and solidified to finally obtain polypropylene fibers, which are then further processed.

[0003] The Chinese patent publication number CN220765869U discloses a high-strength polypropylene particle conveying device for braiding. By turning the loose nut, the feed pipe is freed from restraint, and the feed pipe can be moved longitudinally to adjust the longitudinal length so as to be suitable for conveying mixing drums of different heights and expand the scope of use. The design of the baffle can prevent the polypropylene particles from overflowing from the chute position and causing waste of resources; by turning the screw, the slider can be pushed to move, driving the support leg to move upward, so that the roller extends out of the support leg to push the auger conveying drum to move. The design of the fixed block, screw and slider can facilitate the retraction or extension of the roller so that the support leg supports the ground for stable support.

[0004] However, when the polypropylene particle conveying device is conveying polypropylene particles, as more polypropylene particles are added to the auger conveying cylinder, these large numbers of polypropylene particles will pile up and squeeze each other, and then easily form a blockage phenomenon called "bridging" at the entrance, resulting in the polypropylene particles being unable to fall normally and being accumulated near the entrance in large quantities, making it difficult to convey the polypropylene particles, thereby affecting the conveying efficiency of the polypropylene. Summary of the invention

[0005] The object of the present invention is to provide a raw material conveying device for non-woven fabric processing, so as to solve the problem that polypropylene particles are blocked and cannot fall normally as mentioned in the above background technology.

[0050] The screening mechanism 3 is arranged inside the feed frame 201. The screening mechanism 3 includes a filter plate 301 located inside the feed frame 201. An elastic member 303 is fixedly installed on the side of the filter plate 301. A support rod 304 is fixedly installed on the side of the filter plate 301 away from the elastic member 303.

[0051] Specifically, Figure 6-Figure 8 As shown, the filter plate 301 is located below the dispersion rod 206 , and a mounting groove 302 is provided on the inner wall of the feed frame 201 , and the inner wall of the mounting groove 302 is slidably connected to the outer wall of the filter plate 301 .

[0052] In this embodiment, the filter plate 301 is provided to filter and screen the polypropylene particles, so that the polypropylene particles fall evenly and are not easily blocked.

[0053] Specifically, Figure 6-Figure 8 As shown, a plurality of elastic members 303 are provided, and the other ends of the plurality of elastic members 303 are fixedly connected to the inner wall of one side of the installation groove 302 , and the other end of the support rod 304 slides through the inner wall of the installation groove 302 and extends to the outside of the feed frame 201 .

[0054] In this embodiment, the elastic member 303 is provided to apply a continuous forward elastic force to the filter plate 301 , and the support rod 304 is provided to push and support the filter plate 301 .

[0055] Specifically, Figure 6-Figure 8 As shown, a wedge-shaped strip 305 is fixedly installed on the side of the adjustment plate 210 by bolts, and a wedge-shaped groove 306 is formed on the wedge-shaped surface of the wedge-shaped strip 305 , and the inner wall of the wedge-shaped groove 306 is slidably connected to one end of the support rod 304 .

[0056] In this embodiment, when the adjusting plate 210 moves back and forth, the wedge-shaped bar 305 is driven to move back and forth up and down. The wedge-shaped groove 306 on the wedge-shaped bar 305 squeezes one end of the support rod 304 and cooperates with the elastic member 303, so that the filter plate 301 shakes, further sieving and filtering the polypropylene particles, thereby improving the uniformity and efficiency of the falling of the polypropylene particles.

When the adjusting plate 210 moves up and down, the cylinder 212 and the moving bar 203 are driven to move left and right through the inclined slot 211. The two moving bars 203 drive the dispersion rod 1 206 and the dispersion rod 2 207 below to move left and right, so that the dispersion rod 1 206 and the dispersion rod 2 207 disperse the polypropylene particles, so that more polypropylene particles are not easy to "bridge" in the feed frame 201. The blockage ensures that the polypropylene particles fall normally and evenly, and the transportation efficiency is improved. When the adjusting plate 210 moves back and forth, the adjusting plate 210 drives the wedge bar 305 to move back and forth, and the inner wall of the wedge groove 306 on the wedge bar 305 squeezes the support rod 304, and cooperates with the elastic member 303 to make the filter plate 301 rock back and forth, and the filter plate 301 filters the polypropylene particles. The polypropylene particles fall evenly into the feed pipe 102, further ensuring that the polypropylene particles are not easy to cause blockage, and improving the polypropylene transportation efficiency during the non-woven fabric processing. Then the polypropylene particles fall into the conveying pipe 1, and the power component 104 drives the conveying auger 105 to rotate to transport the polypropylene particles in the conveying pipe 1 to the discharge pipe 101 and discharge them into the processing container.
