Description

Technical Field

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

[0002] The double-sided needle punching device works by forcing the surface and some inner layers of fibers into the fiber web as the needle passes through it. Due to the friction between the fibers, the originally loose fiber web is compressed. When the needle withdraws from the fiber web, the inserted fiber bundles detach from the barbs and remain in the fiber web. Many fiber bundles become entangled in the fiber web, preventing it from returning to its original loose state. After many needle punches, a considerable number of fiber bundles are inserted into the fiber web, and the fibers in the fiber web become intertwined. This device is often used to isolate building materials with different physical properties. The use of the double-sided needle punching device helps to improve the production efficiency of the product.

[0003] Existing double-sided needle-punching devices have a relatively complex needle-punching structure, which makes them inconvenient to promote and use, and also makes it difficult to adjust the depth of needle insertion. The device of this utility model has a simpler needle-punching structure and makes it easier for workers to adjust the depth of needle insertion. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided needle punching device for processing non-woven geotextiles, which solves the problems of complex needle punching structure, inconvenience in promotion and use, and inconvenience in adjusting the depth of needle insertion.

[0005] To achieve the above objectives, a double-sided needle punching device for processing nonwoven geotextiles is provided, comprising: a mounting frame, rotating rods rotatably connected between the two inner walls of the mounting frame, two rotating rods respectively disposed at the upper and lower parts of the mounting frame, two limiting plates fixedly connected to the inner wall of the mounting frame, pushing blocks fixedly connected to the side surfaces of the two rotating rods, moving rods slidably connected inside the two limiting plates, a driving ring fixedly connected to the end of the two moving rods near the rotating rods, the inner wall of the driving ring slidably connected to the side of the pushing block, and an adjusting plate fixedly connected to the end of the two moving rods away from the driving ring, two springs fixedly connected between the upper surface of the adjusting plate and the lower surface of the limiting plate. This device facilitates the processing of nonwoven geotextiles, has a simple structure, and is easy to promote.

[0006] A second motor is fixedly connected to the side of each of the two adjusting plates. A bidirectional lead screw is fixedly connected to the output end of each of the two second motors. The end of each bidirectional lead screw away from the second motor is rotatably connected to the inner wall of the adjusting plate. A mounting plate is slidably connected inside each of the two adjusting plates. Multiple needles are fixedly connected to the lower surface of each of the two mounting plates. Two sliders are provided on the outside of each of the two bidirectional lead screws. Limiting blocks are fixedly connected to the lower surface of each slider. A sliding groove is provided on the upper surface of each of the two mounting plates. The limiting blocks are slidably connected to the inner wall of the sliding groove via a slide rail. The lower surface of the sliders is slidably connected to the upper surface of the mounting plate, which allows the operator to adjust the insertion depth of the needles as needed.

[0007] According to the double-sided needle punching device for processing non-woven geotextiles, one end of each of the two rotating rods extends to the outside of the mounting frame and is fixedly connected to a sprocket. Both sprockets are fitted with chains, and the sprockets and chains cooperate with each other to facilitate the synchronous rotation of the rotating rods.

[0008] According to the double-sided needle punching device for processing non-woven geotextiles, a first motor is fixedly connected to the side of the mounting frame, and the output end of the first motor is fixedly connected to the side of one of the sprockets. The first motor facilitates the provision of power for processing.

[0009] According to the double-sided needle punching device for processing non-woven geotextiles, the two sides of the mounting frame are connected to a first fixing plate and a second fixing plate by fixing bolts. A winding rod is rotatably connected between the side of the first fixing plate and the side of the second fixing plate, which facilitates the unwinding and winding of the non-woven geotextile.

[0010] According to the double-sided needle punching device for processing non-woven geotextiles, a third motor is fixedly connected to the sides of two first fixed plates. The output end of the third motor is fixedly connected to one end of the winding rod. The rotation of the third motor facilitates the provision of tension for winding, which is convenient for processing.

[0011] According to the double-sided needle punching device for processing non-woven geotextiles, the lower surface of the slider is provided with an inclined surface, and the upper surface of the mounting plate is provided with an inclined surface to facilitate the movement of the slider, thereby driving the mounting plate to move.

[0012] According to the double-sided needle punching device for processing non-woven geotextiles, the driving ring is elliptical and the moving rod is square. The elliptical driving ring facilitates the driving of the moving rod for processing, while the square moving rod increases the stability of movement.

[0013] According to the aforementioned double-sided needle punching device for processing non-woven geotextiles, a plurality of needles are evenly arranged to facilitate the processing of non-woven geotextiles.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. When processing is required, the first motor rotates, which drives the rotating rod, which in turn drives the pushing block to rotate. The rotation of the pushing block cooperates with the elliptical driving ring, which facilitates the sliding of the square moving rod inside the limiting plate. The spring pull drives the moving rod to move upward, which facilitates cooperation with the pushing block, allowing the moving rod to slide up and down. The limiting plate can limit the square moving rod, which facilitates the processing of the needle. The structure is relatively simple and easy to promote.

[0016] 2. When the insertion depth needs to be adjusted, the second motor rotates, which in turn drives the bidirectional lead screw to rotate, facilitating the movement of the two sliders in opposite directions. The limit block cooperates with the slide groove to facilitate the up and down movement of the mounting plate. The inclined surface of the slider cooperates with the inclined surface of the mounting plate to facilitate the synchronous movement of the mounting plate when the slider moves, allowing the operator to adjust the insertion depth of the needle as needed.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] One end of each of the two rotating rods 10 extends to the outside of the mounting frame 1 and is fixedly connected to a sprocket 3. Both sprockets 3 are fitted with chains to make the two rotating rods 10 move synchronously. The side of the mounting frame 1 is fixedly connected to a first motor 2 to provide power.
