Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production equipment, and more specifically, to a surface cleaning device for nonwoven fabric production. 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 polyester fiber material. It is made through needle punching process and can be made in different thicknesses, feel, hardness, etc. During the production process, the surface of non-woven fabric is easily contaminated with various impurities, which affects the product quality. Therefore, surface cleaning equipment is needed to clean the non-woven fabric.

[0003] A search revealed a Chinese utility model patent with publication number "CN222557302U" that discloses a surface cleaning device for non-woven fabric production. This device uses a control mechanism to drive a cleaning mechanism to move back and forth, allowing for a more comprehensive cleaning of the non-woven fabric surface. This results in better cleaning effect and higher efficiency. By incorporating a clamping mechanism, one end of the non-woven fabric is wound onto a take-up drum. Activating the clamping mechanism drives the take-up drum to rotate, winding the cleaned non-woven fabric onto the drum. This facilitates the collection of the cleaned non-woven fabric and improves the applicability of the cleaning device.

[0004] The aforementioned document describes a cleaning mechanism that drives a control system to clean nonwoven fabrics. However, during the production process, nonwoven fabrics accumulate a large amount of static electricity, which attracts dust and other contaminants. If this static electricity is not addressed, it will negatively impact the cleaning efficiency of the cleaning system, potentially leading to incomplete cleaning. Furthermore, the cleaned nonwoven fabrics will re-attract dust due to static electricity, resulting in re-contamination. Therefore, existing surface cleaning equipment is ineffective for cleaning nonwoven fabrics. In light of this, we propose a surface cleaning device for nonwoven fabric production. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a surface cleaning device for non-woven fabric production to solve the technical problem that the current surface cleaning devices do not have a good cleaning effect on non-woven fabrics.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a surface cleaning device for non-woven fabric production, including a base, a limiting structure arranged on the front side of the top of the base, a winding structure arranged on the rear side of the top of the base, two sets of symmetrical guide rollers arranged on both sides of the top of the base, and the two sets of guide rollers are located between the limiting structure and the winding structure, a surface cleaning structure and an antistatic structure are arranged on the top of the base between the two sets of guide rollers, the surface cleaning structure is close to the rear guide roller, the antistatic structure is close to the front guide roller, the antistatic structure includes a bracket, an adjustment structure and an ion bar, the bracket is arranged on the base, the adjustment structure is arranged at the top of the bracket, and the ion bar is arranged between the two sets of adjustment structures;

[0007] The bottom air outlet of the ion air bar is provided with an air guide hood. The air guide hood is triangular in shape and gradually flattens from top to bottom. The bottom opening of the air guide hood is rectangular. A herringbone-shaped baffle is movably arranged inside the rectangular opening at the bottom of the air guide hood.

[0008] This invention incorporates an antistatic structure on the side of the base near the limiting structure. When cleaning the nonwoven fabric surface, the angle of the ion bar can be adjusted to a 45-degree angle for forward blowing. As the nonwoven fabric passes under the ion bar, the bar generates an airflow carrying a large number of positive and negative ions, which is then blown onto the nonwoven fabric through the bottom outlet. The positive and negative ions in the airflow neutralize the static ions on the nonwoven fabric, thus eliminating static electricity. This ensures the nonwoven fabric remains static-free during subsequent surface cleaning. When using a surface cleaning structure, the cleaning effect on the non-woven fabric surface is enhanced. Secondly, it prevents the static electricity on the cleaned non-woven fabric from re-attracting dust, thus avoiding secondary contamination and maximizing the cleaning effect. This invention also incorporates an air guide hood at the bottom air outlet of the ion bar. The air guide hood is triangular in shape, gradually flattening from top to bottom, with a rectangular opening at the bottom. An adjustable herringbone-shaped baffle is then installed within this rectangular opening. The ionized airflow from the ion bar, exiting through the air outlet, enters the baffle. The airflow enters the air guide shroud, and then, with the gradually flattening inner cavity inside the shroud, the airflow is ejected in a triangular diffusion pattern, finally exiting from the strip-shaped bottom opening of the air guide shroud. This transforms the circular airflow into a triangular, outward-expanding, straight-line airflow, while maintaining the airflow injection pressure. Furthermore, when destaticating thin non-woven fabrics, the herringbone-shaped guide plate can be adjusted to be centered at the bottom opening of the air guide shroud. This splits the ion airflow, and the split ion airflow, guided by the herringbone-shaped guide plate, will flow smoothly and abundantly. When blowing static electricity onto thicker nonwoven fabrics, the herringbone-shaped air guide plate can be adjusted to fit tightly against the inner wall of the bottom opening of the air guide hood. Then, the entire ion airflow is blown forcefully onto the nonwoven fabric through the bottom opening of the air guide hood, increasing the penetration strength and ensuring that the ion airflow can fully contact the static ions on the thicker nonwoven fabric, thus better achieving the static electricity removal effect. In this way, with the cooperation of the air guide hood and the herringbone-shaped air guide plate, different airflow spray states can be adjusted according to the thickness of the nonwoven fabric, thereby enabling it to better complete the static electricity removal work on the nonwoven fabric.

[0009] Preferably, the adjustment structure includes a rotating structure and a positioning structure, wherein the positioning structure is arranged on the support, and the rotating structure is rotatably arranged on the support.

[0010] Preferably, the rotating structure includes a disc base, which is rotatably arranged on a support, and a concave frame is arranged on the side of the disc base facing away from the support, the concave frame being connected to the ion wind bar.

[0011] Preferably, the positioning structure includes a mounting bracket and a pin. The mounting bracket is arranged on the support, and the pin passes through the mounting bracket and the support. A limiting plate is arranged on the pin and the limiting plate is located inside the mounting bracket. A spring is arranged on the side of the limiting plate opposite to the mounting bracket and is sleeved on the pin. A pull ring is arranged on the outer end of the pin.

[0012] Preferably, the disc base has several sets of equidistant through holes around its edge, and the pin corresponds to the through hole at the top of the disc base.

[0013] Preferably, a fixing frame is arranged on the air guide cover. The fixing frame includes a rectangular frame that is fitted onto the air guide cover. The rectangular frame has top fixing bolts corresponding to the air guide cover arranged at the front and rear. T-shaped connecting frames are arranged on both sides of the top of the rectangular frame, and the T-shaped connecting frames are connected to the concave frame.

[0014] Preferably, round rods are symmetrically arranged inside the rectangular opening at the bottom of the air guide shroud, and the round rods pass through the herringbone-shaped guide plate. An adjusting screw is rotatably arranged in the center of the rectangular opening at the bottom of the air guide shroud, and the adjusting screw passes through the herringbone-shaped guide plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model incorporates an antistatic structure on the side of the base near the limiting structure. When cleaning the nonwoven fabric surface, the angle of the ion bar can be adjusted to a 45-degree tilt. As the nonwoven fabric passes under the ion bar, the bar generates an airflow with a large number of positive and negative ions, which is then blown onto the nonwoven fabric through the bottom air outlet. The positive and negative ions in the airflow neutralize the static ions on the nonwoven fabric, thus eliminating static electricity. This ensures the cleaning effect of the surface cleaning structure on the nonwoven fabric surface when it subsequently passes through it, and prevents the static electricity on the cleaned nonwoven fabric from attracting dust again, causing secondary pollution. This greatly ensures the cleaning effect on the nonwoven fabric surface and solves the technical problem of poor cleaning effect of current surface cleaning equipment. Therefore, this utility model has the advantage of better cleaning effect on nonwoven fabric surfaces.

[0017] 2. This utility model also incorporates an air guide hood at the bottom outlet of the ion bar. The air guide hood is triangular in shape and gradually flattens from top to bottom. The bottom opening of the air guide hood is rectangular, and an adjustable herringbone-shaped guide plate is installed inside the rectangular opening. The ionized airflow discharged from the ion bar through the outlet enters the air guide hood. The gradually flattening inner cavity of the air guide hood causes the airflow to diffuse in a triangular pattern before exiting from the bottom opening. This transforms the circular airflow into a triangular, outward-expanding, linear airflow, while maintaining the airflow pressure. Furthermore, when destaticating thin non-woven fabrics, the herringbone-shaped guide plate can be adjusted. Located at the bottom opening of the air guide hood, the ion airflow can be split. Guided by the herringbone-shaped guide plate, the split ion airflow will be blown smoothly and over a wide area toward the non-woven fabric. When removing static electricity from thicker non-woven fabrics, the herringbone-shaped guide plate can be adjusted to fit tightly against the inner wall of the bottom opening of the air guide hood. Then, the entire ion airflow will be blown forcefully toward the non-woven fabric through the bottom opening of the air guide hood, improving penetration strength and ensuring that the ion airflow can fully contact the static ions on the thicker non-woven fabric, thus better achieving the effect of removing static electricity from the non-woven fabric. Therefore, with the cooperation of the air guide hood and the herringbone-shaped guide plate, different airflow spray states can be adjusted according to the thickness of the non-woven fabric, thereby enabling it to better complete the static removal work of the non-woven fabric.

Detailed Implementation

[0028] like Figures 1 to 8 As shown, this utility model relates to a surface cleaning device for nonwoven fabric production, including a base 1. A limiting structure 2 is arranged on the front side of the top of the base 1, and a winding structure 3 is arranged on the rear side of the top of the base 1. Two sets of symmetrical guide rollers 4 are arranged on both sides of the top of the base 1, and the two sets of guide rollers 4 are located between the limiting structure 2 and the winding structure 3. A surface cleaning structure 5 and an antistatic structure 6 are arranged on the top of the base 1 between the two sets of guide rollers 4. The surface cleaning structure 5 is close to the rear guide roller 4, and the antistatic structure 6 is close to the front guide roller 4. The antistatic structure 6 includes a support 7, an adjustment structure 8, and an ion bar 13. The support 7 is arranged on the base 1, the adjustment structure 8 is arranged at the top of the support 7, and the ion bar 13 is arranged between the two sets of adjustment structures 8. The limiting structure 2, the winding structure 3, and the surface cleaning structure 5 are referenced in a surface cleaning device for nonwoven fabric production with the publication number "CN222557302U", which is the prior art.

[0029] When cleaning the surface of the nonwoven fabric, the nonwoven fabric enters from the limiting structure 2, then passes through the guide roller 4, the ion air bar 13, the surface cleaning structure 5 and the guide roller 4, and finally wraps around the winding structure 3. Then, the angle of the ion air bar 13 is adjusted by the adjusting structure 8, so that the ion air bar 13 can be in a 45-degree tilted forward blowing state.

[0030] The nonwoven fabric is moved by the winding structure 3. When the nonwoven fabric passes under the ion bar 13, the ion bar 13 works to generate an airflow with a large number of positive and negative ions. The airflow is blown onto the nonwoven fabric through the air outlet at its bottom. Then, the positive and negative ions in the airflow neutralize the static ions on the nonwoven fabric, thereby eliminating the static electricity on the nonwoven fabric. Firstly, this ensures the cleaning effect of the surface cleaning structure 5 on the surface of the nonwoven fabric when it passes through the surface cleaning structure 5. Secondly, it avoids the static electricity on the cleaned nonwoven fabric from attracting dust again and causing secondary pollution to the nonwoven fabric. This greatly ensures the cleaning effect on the surface of the nonwoven fabric.

[0031] When the nonwoven fabric passes through the surface cleaning structure 5, the surface cleaning structure 5 cleans the surface of the nonwoven fabric after the static electricity has been eliminated, ensuring the cleaning effect of the surface cleaning structure 5 on the surface of the nonwoven fabric.

[0032] Specifically, the adjustment structure 8 includes a rotating structure 9 and a positioning structure 10. The positioning structure 10 is arranged on the bracket 7, and the rotating structure 9 is rotatably arranged on the bracket 7. The rotating structure 9 includes a disc seat 901, which is rotatably arranged on the bracket 7. A concave frame 903 is arranged on the side of the disc seat 901 facing away from the bracket 7, and the concave frame 903 is connected to the ion air bar 13. The positioning structure 10 includes a mounting frame 1001 and a pin 1002. The mounting frame 1001 is arranged on the bracket 7, and the pin 1002 passes through the mounting frame 1001 and the bracket 7. A limiting plate 1003 is arranged on the pin 1002, and the limiting plate 1003 is located inside the mounting frame 1001. A spring 1004 is arranged on the opposite side of the limiting plate 1003 and the mounting frame 1001, and the spring 1004 is sleeved on the pin 1002. A pull ring 1005 is arranged on the outer end of the pin 1002; several sets of equidistant through holes 902 are opened around the edge of the disc base 901, and the pin 1002 corresponds to the through hole 902 on the top of the disc base 901; the disc base 901 is connected and installed to the ion air rod 13 through the concave bracket 903. Then, by holding the pull ring 1005, the pin 1002 is pulled to disengage from the through hole 902. With the cooperation of the disc base 901, the ion air rod 13 can be rotated, thereby adjusting the angle of the ion air rod 13. After the angle of the ion air rod 13 is adjusted, the pull ring 1005 can be released. With the reset cooperation of the spring 1004, the pin 1002 is reset and inserted into the corresponding through hole 902 of the disc base 901, thereby fixing the disc base 901, that is, fixing the ion air rod 13.

[0033] In an embodiment of this utility model, an air guide shroud 11 is arranged at the bottom air outlet of the ion air bar 13. The air guide shroud 11 is triangular in shape and gradually flattens from top to bottom. The bottom opening of the air guide shroud 11 is rectangular. A herringbone-shaped guide plate 1101 is movably arranged inside the rectangular opening at the bottom of the air guide shroud 11. Round rods 1102 are symmetrically arranged inside the rectangular opening at the bottom of the air guide shroud 11, and the round rods 1102 pass through the herringbone-shaped guide plate 1101. An adjusting screw 1103 is rotatably arranged in the center of the rectangular opening at the bottom of the air guide shroud 11, and the adjusting screw 1103 passes through the herringbone-shaped guide plate 1101.

[0034] The ion airflow discharged from the ion bar 13 through the air outlet enters the air guide shroud 11. Then, with the gradually flattening inner cavity of the air guide shroud 11, the airflow is sprayed in a triangular diffusion state, finally exiting from the strip-shaped bottom opening of the air guide shroud 11. This transforms the circular spray airflow into a triangular, outward-expanding, straight-line spray airflow, while maintaining the spray pressure. Furthermore, when destaticating thin non-woven fabrics, the herringbone-shaped guide plate 1101 can be centered at the bottom opening of the air guide shroud 11 by turning the adjusting screw 1103. This splits the ion airflow, and the split ion airflow then passes through the herringbone-shaped guide plate 1101. Guided by 1, the airflow will gently and over a wide area blow towards the nonwoven fabric. When removing static electricity from thicker nonwoven fabrics, the herringbone guide plate 1101 can be adjusted to be tightly attached to the inner wall of the bottom opening of the air guide shroud 11 by turning the adjusting screw 1103. Then, the entire ion airflow will be blown towards the nonwoven fabric in a strong state through the bottom opening of the air guide shroud 11, improving the penetration strength and ensuring that the ion airflow can fully contact the static ions on the thicker nonwoven fabric, thus better achieving the effect of removing static electricity from the nonwoven fabric. Therefore, with the cooperation of the air guide shroud 11 and the herringbone guide plate 1101, different airflow spray states can be adjusted according to the thickness of the nonwoven fabric, thereby enabling it to better complete the static electricity removal work of the nonwoven fabric.

[0035] Specifically, a fixing frame 12 is arranged on the air guide cover 11. The fixing frame 12 includes a rectangular frame 1201, which is fitted onto the air guide cover 11. The rectangular frame 1201 has top fixing bolts 1203 corresponding to the air guide cover 11 arranged at the front and rear. T-shaped connecting frames 1202 are arranged on both sides of the top of the rectangular frame 1201, and the T-shaped connecting frames 1202 are connected to the concave frame 903. The rectangular frame 1201 is connected and fixed to the concave frame 903 through the T-shaped connecting frames 1202. Then, the personnel tighten the top fixing bolts 1203 at the front and rear of the rectangular frame 1201 to make it press against the corresponding air guide cover 11, thereby stabilizing the air guide cover 11 and ensuring the stability of the horizontal installation of the air guide cover 11, preventing rotation.

[0036] Working principle: This embodiment provides a surface cleaning device for non-woven fabric production. First, when cleaning the surface of the non-woven fabric, the non-woven fabric enters from the limiting structure 2, then passes through the guide roller 4, the ion air bar 13, the surface cleaning structure 5 and the guide roller 4, and finally winds onto the winding structure 3. Then, the angle of the ion air bar 13 is adjusted by the adjusting structure 8, so that the ion air bar 13 can be in a 45-degree inclined forward blowing state.

[0037] Secondly, the nonwoven fabric is moved by the winding structure 3. When the nonwoven fabric passes under the ion bar 13, the ion bar 13 works to generate an airflow with a large number of positive and negative ions. The airflow is blown toward the nonwoven fabric through the air outlet at its bottom. Then, the positive and negative ions in the airflow neutralize the static ions on the nonwoven fabric, thereby eliminating the static electricity on the nonwoven fabric. Firstly, this ensures the cleaning effect of the surface cleaning structure 5 on the surface of the nonwoven fabric when it passes through the surface cleaning structure 5 later. Secondly, it avoids the static electricity on the cleaned nonwoven fabric from attracting dust again, causing secondary pollution to the nonwoven fabric. This greatly ensures the cleaning effect on the surface of the nonwoven fabric.

[0038] Secondly, when the nonwoven fabric passes through the surface cleaning structure 5, the surface cleaning structure 5 cleans the surface of the nonwoven fabric after the static electricity is eliminated, ensuring the cleaning effect of the surface cleaning structure 5 on the surface of the nonwoven fabric.

[0039] Finally, the ion airflow discharged from the ion bar 13 through the air outlet enters the air guide shroud 11. Then, with the gradually flattening inner cavity of the air guide shroud 11, the airflow is sprayed in a triangular diffusion state, finally exiting from the strip-shaped bottom opening of the air guide shroud 11. This changes the circular spray airflow into a triangular, outward-expanding, straight-line spray airflow, while maintaining the spray pressure. Furthermore, when destaticating thin non-woven fabrics, the herringbone-shaped guide plate 1101 can be centered at the bottom opening of the air guide shroud 11 by turning the adjusting screw 1103. This allows the ion airflow to be split, and the split ion airflow then passes through the herringbone-shaped guide plate 1101. Guided by 101, the airflow will gently and over a wide area be blown toward the nonwoven fabric. When removing static electricity from thicker nonwoven fabrics, the herringbone guide plate 1101 can be adjusted to be tightly attached to the inner wall of the bottom opening of the air guide shroud 11 by turning the adjusting screw 1103. Then, the ion airflow will be blown toward the nonwoven fabric in a strong state through the bottom opening of the air guide shroud 11, which will improve the penetration strength and ensure that the ion airflow can fully contact the static ions on the thicker nonwoven fabric, thus better achieving the effect of removing static electricity from the nonwoven fabric. Thus, with the cooperation of the air guide shroud 11 and the herringbone guide plate 1101, different airflow spray states can be adjusted according to the thickness of the nonwoven fabric, thereby enabling it to better complete the static electricity removal work of the nonwoven fabric.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
