Technical Field
[0001] This utility model relates to the field of meltblown fabric production technology, and in particular to a cleaning device for a meltblown fabric production conveying system. Background Technology
[0002] As a core component of products such as masks and air filtration materials, the cleanliness of meltblown fabric during its production process directly affects the performance and safety of the end products. In the meltblown fabric production and conveying system, the cleaning device is a key piece of equipment to ensure product quality. It is mainly used to remove electrostatically adsorbed impurities, polymer residues, oil stains, and dust and other pollutants mixed in during the production process from the surface of the meltblown fabric.
[0003] Most existing cleaning devices use a single cleaning method, which is difficult to effectively remove various contaminants from the surface of meltblown fabric. They are not effective at cleaning deep impurities in the microporous structure, and the cleaning force is uneven, which can easily cause damage to the surface of meltblown fabric or insufficient cleaning. In order to address this technical problem, this application proposes a cleaning device for a meltblown fabric production conveying system. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cleaning device for a meltblown fabric production conveying system. This device effectively removes static electricity and various impurities from the surface of the meltblown fabric through multiple cleaning methods, including ion wind static elimination, airflow purging, and flexible scraping. This improves the cleaning quality. Furthermore, by adjusting the angle of the air jet nozzle, it can adapt to different impurity purging requirements, enhancing the comprehensiveness of cleaning. Adjusting the height of the flexible scraper ensures effective removal of stubborn stains while avoiding excessive compression and damage to the meltblown fabric.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A cleaning device for a meltblown fabric production conveying system includes a support platform. A protective shell is fixedly connected to the upper end of the support platform. A U-shaped plate is connected to the inside of the protective shell via a rotating assembly. Multiple connecting pipes are fixedly connected to the lower part of the U-shaped plate. Multiple air nozzles are installed at the lower end of the connecting pipes. An air inlet assembly is provided at the upper part of the connecting pipes. An ion air bar is installed on the left side inside the protective shell. A flexible scraper is connected to the right side inside the protective shell via a lifting assembly. A vacuum adsorption chamber is installed inside the protective shell. A collection box is installed inside the vacuum adsorption chamber.
[0007] Furthermore, the rotating assembly includes a rotating shaft that is fixedly connected to both the front and rear ends of the U-shaped plate. The outer wall of the rotating shaft is rotatably connected to both the front and rear ends of the inner wall of the protective shell, and a half gear is fixedly connected to the outer wall of the rotating shaft on the front side.
[0008] Furthermore, the rotating assembly also includes an electric push rod two mounted on the front end of the protective shell. The drive end of the electric push rod two is fixedly connected to a rack. The upper end of the rack is meshed with the outer wall of the half gear, and the rear end of the rack is slidably connected to the front end of the protective shell.
[0009] Furthermore, the air intake assembly includes a blower mounted on the upper end of the protective shell, an air intake pipe fixedly connected to the air inlet of the blower, an air outlet pipe fixedly connected to the air outlet of the blower, a telescopic hose fixedly connected to the other end of the air outlet pipe, and the lower end of the telescopic hose fixedly connected to the upper part of the connecting pipe.
[0010] Furthermore, an air outlet branch pipe is fixedly connected to the right side of the outer wall of the main air outlet pipe, and the other end of the air outlet branch pipe is installed at the front end of the ion bar.
[0011] Furthermore, the lifting assembly includes sliding grooves at both the front and rear ends of the inner wall of the protective shell, with a slider slidably connected inside the sliding groove, and one end of the slider being fixedly connected to the front and rear ends of the flexible scraper.

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, static electricity is eliminated by ion air bar to reduce the adsorption force between impurities and meltblown cloth, and most of the impurities are swept away by airflow from jet nozzle. Finally, stubborn impurities are scraped off by flexible scraper. Through the synergistic effect of multiple cleaning methods, the cleaning effect and efficiency are greatly improved. Moreover, the design of vacuum adsorption chamber and collection box can collect impurities generated during the cleaning process in a timely and effective manner, preventing impurities from re-adhering to meltblown cloth and ensuring the cleaning quality of meltblown cloth.
[0016] 2. In this utility model, by controlling the extension and retraction of the electric push rod II, the rotation angle and direction of the U-shaped plate can be precisely controlled, thereby changing the angle of the air nozzle. This allows the airflow to sweep from different angles according to the contamination status of different parts of the meltblown fabric, thereby improving the comprehensiveness and targeting of cleaning and effectively removing impurities from various locations on the surface of the meltblown fabric. By controlling the height of the flexible scraper, it is ensured that while effectively scraping away stubborn stains, the meltblown fabric will not be excessively squeezed or damaged.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a cleaning device for a meltblown fabric production conveying system, comprising a support platform 1, a protective shell 2 fixedly connected to the upper end of the support platform 1, a U-shaped plate 12 connected to the inside of the protective shell 2 via a rotating assembly, multiple connecting pipes 10 fixedly connected to the lower part of the U-shaped plate 12, multiple air nozzles 11 installed at the lower end of the connecting pipes 10, and an air inlet assembly provided at the upper part of the connecting pipes 10. The air inlet assembly includes a blower 6 installed at the upper end of the protective shell 2, an air inlet pipe 7 fixedly connected to the air inlet of the blower 6, and an air outlet pipe 8 fixedly connected to the air outlet of the blower 6. The other end of the pipe 8 is fixedly connected to a telescopic hose 9. The lower end of the telescopic hose 9 is fixedly connected to the upper part of the connecting pipe 10. An ion air bar 14 is installed inside the left side of the protective shell 2. An air outlet branch pipe 13 is fixedly connected to the right side of the outer wall of the main air outlet pipe 8. The other end of the air outlet branch pipe 13 is installed at the front end of the ion air bar 14. A flexible scraper 16 is connected inside the right side of the protective shell 2 through a lifting assembly. A vacuum adsorption chamber 5 is installed inside the protective shell 2. A collection box is installed inside the vacuum adsorption chamber 5. A feed roller 3 is installed on the upper left side of the support platform 1. A discharge roller 4 is installed on the upper right side of the support platform 1.
[0024] Specifically, during the production process, the meltblown fabric is fed into the protective shell 2 by the feed roller 3, cleaned, and then discharged by the discharge roller 4. The feed roller 3 and discharge roller 4 guide and convey the meltblown fabric, ensuring its smooth movement within the cleaning device. The blower 6 is started, drawing air in through the air inlet pipe 7, which then enters the main air outlet pipe 8 through the air outlet, and is then transported to the connecting pipe 10 via the telescopic hose 9. Finally, the air is ejected from the nozzle 11 at the lower end of the connecting pipe 10. The ejected airflow directly acts on the surface of the meltblown fabric, blowing away impurities that have become easily detached after electrostatic elimination. The telescopic hose 9 ensures smooth airflow delivery when the U-shaped plate 12 is rotated to adjust the angle, preventing changes in angle from affecting airflow transmission. Simultaneously, the air generated by the blower 6 enters the ion bar 14 through the main air outlet pipe 8 and the branch air outlet pipe 13. When the ion bar 14 is working, it releases ions onto the surface of the meltblown fabric with the help of the introduced airflow, neutralizing... The static electricity generated during the production of meltblown fabric is neutralized, making it easier to remove dust, tiny particles, and other impurities that were originally attracted to the surface of the meltblown fabric by static electricity in subsequent cleaning steps. During the movement of the meltblown fabric, the flexible scraper 16 can scrape off stubborn stains, residual fibers, and other impurities that cannot be removed by air jet alone. The vacuum adsorption chamber 5 remains in working condition during the cleaning process, generating negative pressure inside. Impurities blown away or scraped off during the cleaning process are sucked into the vacuum adsorption chamber 5 under the action of negative pressure and collected in the collection box inside, preventing impurities from flying around in the protective shell 2 and causing secondary pollution. It also facilitates the subsequent centralized cleaning of impurities. Static electricity is eliminated by the ion air bar 14, reducing the adsorption force between impurities and meltblown fabric. Then, the airflow blown by the air jet nozzle 11 sweeps away most of the impurities. Finally, the flexible scraper 16 scrapes off stubborn impurities. The synergistic effect of multiple cleaning methods greatly improves the cleaning effect and efficiency.
[0025] Reference Figure 1 and Figure 3 The rotating assembly includes a rotating shaft 21 fixedly connected to both the front and rear ends of a U-shaped plate 12. The outer wall of the rotating shaft 21 is rotatably connected to both the front and rear ends of the inner wall of the protective shell 2. A half gear 20 is fixedly connected to the outer wall of the front rotating shaft 21. The rotating assembly also includes an electric push rod 18 installed at the front end of the protective shell 2. A rack 19 is fixedly connected to the drive end of the electric push rod 18. The upper end of the rack 19 is meshed with the outer wall of the half gear 20, and the rear end of the rack 19 is slidably connected to the front end of the protective shell 2.
[0026] Specifically, after the electric push rod 18 is powered on, its drive end performs a linear extension and retraction motion. When the electric push rod 18 extends or retracts, it drives the rack 19, which is fixedly connected to it, to slide linearly at the front end of the protective shell 2. Since the rack 19 and the half gear 20 mesh with each other, the linear motion of the rack 19 is converted into the rotational motion of the half gear 20. The half gear 20 is fixed to the outer wall of the front rotating shaft 21, thereby driving the rotating shaft 21 to rotate. The front and rear ends of the U-shaped plate 12 are fixedly connected to the rotating shaft 21, ultimately realizing the rotation of the U-shaped plate 12 around the rotating shaft 21. By controlling the extension and retraction amount and direction of the electric push rod 18, the rotation angle and rotation direction of the U-shaped plate 12 can be precisely controlled, thereby changing the angle of the air nozzle 11. This allows the airflow to sweep from different angles according to the contamination status of different parts of the meltblown fabric, thereby improving the comprehensiveness and targeting of cleaning and effectively removing impurities from various locations on the surface of the meltblown fabric.
[0027] Reference Figure 1 and Figure 2 The lifting assembly includes sliding grooves opened at both the front and rear ends of the inner wall of the protective shell 2. A slider 17 is slidably connected inside the sliding groove. The opposite end of the slider 17 is fixedly connected to the front and rear ends of the flexible scraper 16. The lifting assembly also includes an electric push rod 15 installed at the upper end of the protective shell 2. The drive end of the electric push rod 15 is fixedly connected to the upper end of the flexible scraper 16.
[0028] Specifically, the electric push rod 15 is activated, causing its drive end to extend or shorten, thereby driving the flexible scraper 16 to move vertically upward or downward. At the same time, the sliders 17 at both ends of the flexible scraper 16 slide within the grooves opened on the inner wall of the protective shell 2, playing a guiding and stabilizing role, ensuring that the flexible scraper 16 remains stable during the lifting and lowering process, without deviation or shaking. The lifting and lowering height of the flexible scraper 16 can be precisely controlled by the electric push rod 15, and thus the contact pressure and distance between the flexible scraper 16 and the surface of the meltblown fabric can be flexibly adjusted according to the thickness, texture and surface contamination of the meltblown fabric, thereby ensuring that while effectively scraping away stubborn stains, the meltblown fabric is not excessively squeezed or damaged.
[0029] Working principle: In operation, first start the meltblown fabric production conveyor system. The meltblown fabric smoothly enters the protective shell 2 from the feed roller 3. Then, start the blower 6 and ion bar 14. The ion bar 14 introduces the air generated by the blower 6 through the outlet branch pipe 13, blowing out ion air to eliminate static electricity on the surface of the meltblown fabric. The airflow drawn in by the blower 6 enters the connecting pipe 10 through the inlet pipe 7, the outlet main pipe 8, and the telescopic hose 9, and is sprayed out from the nozzle 11 to sweep away impurities on the surface of the meltblown fabric. If the jet angle needs to be adjusted, start the electric push rod 18, which pushes the rack 19 to mesh with the half gear 20, driving the U-shaped plate 1. 2. Rotate around the pivot 21 and adjust to a suitable angle before stopping the operation of the electric push rod 2 18. Then, depending on the stubborn stains on the surface of the meltblown fabric, start the electric push rod 1 15, which drives the flexible scraper 16 to slide in the groove through the slider 17. Adjust the flexible scraper 16 to descend to a suitable height so that it lightly touches the surface of the meltblown fabric and scrapes away the stubborn stains. After cleaning, the electric push rod 1 15 drives the flexible scraper 16 to rise and reset. During the cleaning process, the vacuum adsorption chamber 5 continues to work, generating negative pressure to adsorb the fallen impurities into the internal collection box. The cleaned meltblown fabric is sent out from the discharge roller 4, completing one cleaning operation.
