Description

Technical Field

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

[0002] Spunlace nonwoven fabric is a nonwoven material made by piercing a fiber web with high-pressure micro-water flow, causing the fibers to entangle and reinforce each other.

[0003] Folding is a crucial step in the production of spunlace nonwoven fabrics. However, existing spunlace nonwoven fabric folding devices have several problems in practical use. Firstly, during the fabric transmission process, the spunlace nonwoven fabric rollers are prone to up-and-down wobbling. This not only affects the transmission stability of the nonwoven fabric but may also lead to wrinkles, uneven stretching, and other problems, thus impacting the folding quality. Secondly, spunlace nonwoven fabrics may contain loose fibers or impurities during production. If not handled promptly, these loose parts can easily affect the neatness of the folds during folding, reducing product quality. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A folding device for spunlace nonwoven fabric production includes a base 1, which supports the installation of a vertical plate 5. The vertical plate 5 is fixedly installed on the base 1 and supports a folding mechanism 4, an insertion mechanism, a compression mechanism, and a dust collection mechanism. The folding mechanism 4 is mounted on the vertical plate 5, which is existing technology and will not be described in detail. The insertion mechanism, compression mechanism, and dust collection mechanism are also mounted on the vertical plate 5. The insertion mechanism limits the movement of different spunlace nonwoven fabric rollers. The compression mechanism compresses the spunlace nonwoven fabric on the rollers to prevent loosening. The dust collection mechanism removes dust from the spunlace nonwoven fabric, facilitating folding. The insertion mechanism includes an insertion roller 31, which is fixedly mounted on the vertical plate 5. The insertion roller 31 is designed to receive the insertion of the nonwoven fabric roller. The insertion roller 31 has a cavity 35, which is designed to receive the sliding of the slide plate 310. An installation plate 39 is fixedly installed on the inner wall of the cavity 35. A rotating rod 36 is rotatably connected to the installation plate 39. The rotating rod 36 is provided with positive and negative threads. By providing the rotating rod 36 with positive and negative threads, it is used to drive the two slide plates 310 to slide in opposite directions along the inner wall of the cavity 35. The slide plate 310 is threadedly connected to the rotating rod 36. The slide plate 310 slides on the inner wall of the cavity 35. The slide plate 310 is designed to receive the installation of the bracket 33. The bracket 33 is fixedly installed on the slide plate 310. The bracket 33 is designed to receive the rolling of the roller body 32. The roller body 32 is rotatably connected to the bracket 33. By providing the roller body 32, it is used to roll in the central hole of the nonwoven fabric roller.

[0023] The dust collection mechanism includes a slide rod 22, which is fixedly installed on the vertical plate 5. The slide rod 22 is designed to support the sliding of the slider 27. The slider 27 is slidably mounted on the slide rod 22. The slider 27 is designed to support the mounting of the receiving plate 21. The receiving plate 21 is fixedly mounted on the slider 27. A vacuum cleaner 24 is fixedly mounted on the receiving plate 21. The vacuum cleaner 24 is designed to clean the spunlace nonwoven fabric by vacuuming, which facilitates the subsequent folding and processing of the spunlace nonwoven fabric.

[0024] In detail, there are two slide plates 310, both of which are square plates. There are also two roller bodies 32, which are used to roll within the central hole of the nonwoven fabric roller.

[0025] Furthermore, a gear ring 38 is fixedly installed on the rotating rod 36, and a first motor 34 is fixedly installed on the inner wall of the cavity 35. The first motor 34 has forward and reverse rotation functions. The first motor 34 is set to drive the first gear 37 to rotate. The first gear 37 is fixedly installed on the shaft end of the first motor 34. The first gear 37 meshes with the gear ring 38. By setting the first gear 37 and the gear ring 38, the first motor 34 drives the rotating rod 36 to rotate when it is working.

[0026] Furthermore, a second motor 23 is fixedly installed on the back of the vertical plate 5. The second motor 23 is configured to drive the second gear 26 to rotate. The shaft end of the second motor 23 passes through the vertical plate 5 and is fixedly installed with the second gear 26.

[0027] More specifically, two racks 25 are fixedly installed on the side of the slider 27. The two racks 25 mesh with the second gear 26 respectively. By setting the racks 25, when the second gear 26 rotates, it drives the two sliders 27 to slide in opposite directions along the surface of the slide rod 22, thereby achieving the purpose of adjusting the distance between the two vacuum cleaners 24.

[0028] In general, the extrusion mechanism includes a horizontal plate 61, which is fixedly installed on the vertical plate 5. The horizontal plate 61 is square in shape and is vertically arranged. The horizontal plate 61 is used to support the installation of the spring 66.

[0029] Finally, a spring 66 is fixedly installed at the top of the horizontal plate 61. The spring 66 is used to apply force to the extrusion roller 63 so that the extrusion roller 63 is tightly attached to the nonwoven fabric roller to prevent the nonwoven fabric roller from becoming loose. A pull rod 65 is fixedly installed at one end of the spring 66. The pull rod 65 is used to pull the extrusion roller 63 to move. The bottom end of the pull rod 65 passes through the horizontal plate 61 and is fixedly installed with a mounting frame 62. The extrusion roller 63 is rotatably connected to the inner wall of the mounting frame 62. A limit rod 64 is fixedly installed at the top of the mounting frame 62. The top end of the limit rod 64 passes through the horizontal plate 61. There are two limit rods 64, which are symmetrically arranged with the pull rod 65 as the center. Both limit rods 64 are square rods. The limit rods 64 are used to limit the movement of the extrusion roller 63.

[0030] Working method: First, pull the lever 65. The lever 65 will drive the extrusion roller 63 to move to a suitable height position through the mounting bracket 62. Then, the spunlace nonwoven fabric roller is inserted into the insertion roller 31 through its central hole. Then, start the first motor 34. The first motor 34 drives the rotating rod 36 to rotate through the first gear 37 and the gear ring 38. The rotating rod 36 is provided with positive and negative threads, which will drive the two side slide plates 310 to slide in the opposite direction along the inner wall of the cavity 35. When the two side slide plates 310 slide in the opposite direction, they will drive the two side rollers 32 to move in the opposite direction through the bracket 33 until the two side rollers 32 contact the inner wall of the central hole of the spunlace nonwoven fabric roller, thereby achieving the purpose of limiting the spunlace nonwoven fabric roller and preventing the nonwoven fabric roller from shaking up and down during nonwoven fabric transmission.

[0031] After completing the above operations, release the pull rod 65. Under the action of the spring 66, the extrusion roller 63 will be tightly attached to the nonwoven fabric roller. The elasticity of the spring 66 allows the extrusion roller 63 to adapt to nonwoven fabric rollers of different thicknesses, ensuring stable contact and extrusion effect under various working conditions and avoiding loosening.

[0032] After completing the above operations, pass one end of the non-woven fabric between the two vacuum cleaners 24 and into the folding mechanism 4. At this time, start the second motor 23. The second motor 23 drives the gear 26 to rotate. The second gear 26 meshes with the racks 25 on both sides. The racks 25 will drive the sliders 27 on both sides to move towards each other along the surface of the slide bar 22. When the sliders 27 move, they will drive the vacuum cleaners 24 on the receiving plates 21 on both sides to move towards each other until the vacuum cleaners 24 on both sides move to a suitable distance, which is conducive to vacuuming non-woven fabrics of different thicknesses.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
