Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to an environmentally friendly dust removal equipment for non-woven fabric production. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is a type of fabric produced by processing various fiber raw materials with needle rolling or carding machinery and forming or bonding them under high pressure. After production, non-woven fabric needs to be treated with dust removal equipment.

[0003] Currently, existing dust removal devices (such as patent publication number: CN218424566U) disclose a dust removal device for non-woven fabric production. An air pump is installed at the top of the machine casing, with air pipes connected to both ends of the air pump. One end of each air pipe is fitted with an air duct. The advantages are: this invention, through its enclosed structure of the machine casing, waste bin, machine body, air pump, and air duct, prevents dust from scattering freely and avoids dust being inhaled by workers, thus improving the safety of the device during use. Furthermore, the included suction pump, discharge pipe, connecting pipe, and suction port allow for simultaneous dust removal from both sides of the non-woven fabric.

[0004] In the aforementioned patent, the negative pressure of the air inlet is used to adsorb the floating dust on the surface of the non-woven fabric. However, for dust embedded inside the non-woven fabric fibers and adhering to the fibers, the airflow suction is difficult to overcome the adhesion between the dust and the fibers, resulting in a large amount of dust residue and inability to completely remove the dust. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly dust removal device for nonwoven fabric production. It solves the technical problem that while the negative pressure of the air inlet adsorbs floating dust on the surface of the nonwoven fabric, the airflow suction is insufficient to overcome the adhesion between the dust and the fiber for dust embedded inside the nonwoven fabric fibers and adhering to the fibers, resulting in a large amount of dust residue and inability to completely remove the dust.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An environmentally friendly dust removal device for nonwoven fabric production includes two dust housings and a connecting pipe. Each dust housing has multiple guide strips on its inner side and a rubber pad is fixedly installed on the inner side of each dust housing. The device also includes: Multiple spinning assemblies are provided, each of which is disposed inside the dust housing. Each spinning assembly includes a main shaft and a first blade. A second blade is slidably installed inside each first blade. Connecting sleeves are fixedly installed at both ends of each main shaft. Two positioning grooves are provided on the surface of each connecting sleeve.

[0007] Preferably, each of the second blades has multiple oblique protrusions fixedly installed at its top end, each of the second blades has multiple compression rods at its end, each of the connecting sleeves has two limiting blocks on its surface, each limiting block has an elastic rod fixedly installed at its end, and the end of each elastic rod is connected to the inner side of the dust housing.

[0008] Both of the connecting pipes are fixedly installed with the same dust collection box at their side ends. A filter screen is fixedly installed inside the dust collection box. A back plate interface is fixedly installed at the side end of the dust collection box. A pipe is fixedly installed on the surface of the back plate interface. The end of the pipe is connected to a vacuum pump.

[0009] Preferably, each of the dust housings has two fixed seats at its side end, each fixed seat has a guide rod at its side end, the same electric push rod is provided on the inner side of both fixed seats, multiple guide strips on the inner side of each dust housing are distributed in an inclined manner, each of the second blades is guided and slidably connected inside the first blade, and each of the first blades has a groove adapted to the second blade.

[0010] Compared with the prior art, the present invention has the following beneficial effects; In this invention, when the nonwoven fabric slides between the dust collection shells, the second leaf plate rubs against the outer side of the nonwoven fabric, driving the main shaft to rotate. This causes the second leaf plate to intermittently squeeze and impact the nonwoven fabric, vibrating and discharging dust from inside the nonwoven fabric. The oblique convex strip further enhances the squeezing effect and increases the dust removal force of a single impact. At the same time, the second leaf plate slides guided within the groove of the first leaf plate. The end compression rod generates a reverse thrust after being squeezed, ensuring that the second leaf plate is always in close contact with the nonwoven fabric, thus adapting to nonwoven fabrics of different sizes.

[0011] In this invention, multiple guide strips on the inner side of the dust collection housing are distributed at an angle to guide the airflow carrying dust and short fiber debris in a directional manner, forming an orderly guide flow that concentrates towards the inlet of the connecting pipe. The dust collection box is connected to a vacuum pump through the back plate interface to form a negative pressure zone, which draws the dust and short fiber debris inside the dust collection housing into the box. The filter screen can accurately intercept short fiber debris, enabling its reuse and reducing material loss in nonwoven fabric production. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: This application provides an environmentally friendly dust removal device for nonwoven fabric production. It effectively solves the problem of adsorbing floating dust on the surface of nonwoven fabric through negative pressure adsorption of air inlet. However, for dust embedded inside the nonwoven fabric fibers and adhering to the fibers, the airflow suction is difficult to overcome the adhesion between the dust and the fibers, resulting in a large amount of dust residue and incomplete dust removal. When the nonwoven fabric slides between the dust shells, the second leaf plate rubs against the outside of the nonwoven fabric, driving the main shaft to rotate. This causes the second leaf plate to intermittently squeeze and impact the nonwoven fabric, vibrating and discharging the dust from inside the nonwoven fabric. The oblique convex strip further enhances the squeezing effect and increases the dust removal force of a single impact. At the same time, the second leaf plate slides guided in the groove of the first leaf plate. After the end compression rod is squeezed, it generates a reverse thrust, ensuring that the second leaf plate is always in close contact with the nonwoven fabric, adapting to nonwoven fabrics of different sizes.

[0014] Example 1 like Figures 1 to 4 As shown, the technical solution in this application embodiment effectively solves the problem of adsorbing floating dust on the surface of non-woven fabric through negative pressure of the air intake. However, for dust embedded inside the non-woven fabric fibers and adhering to the fibers, the airflow suction is difficult to overcome the adhesion between the dust and the fibers, resulting in a large amount of dust residue and inability to completely remove dust. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides an environmentally friendly dust removal device for non-woven fabric production, including two dust housings 11 and a connecting pipe 12. Each dust housing 11 has multiple guide strips 16 on its inner side and a rubber pad strip 17 fixedly installed on its inner side. By closing the two dust housings 11 together, the two dust housings 11 squeeze the surface of the non-woven fabric. During the squeezing process, the rubber pad strip 17 is deformed by the force and bends to fit the surface of the non-woven fabric, ensuring airtightness. Multiple spinning assemblies are provided, each set inside the dust housing 11. Each spinning assembly includes a main shaft 22 and a first leaf plate 23. A second leaf plate 25 is slidably installed inside each first leaf plate 23. Connecting sleeves 27 are fixedly installed at both ends of each main shaft 22. Each connecting sleeve 27 has two positioning grooves on its surface. When non-woven fabric is placed between two dust housings 11, the second leaf plate 25 rubs against the outer surface of the non-woven fabric. As the non-woven fabric slides between the dust housings 11, the main shaft 22 is driven to rotate inside the dust housing 11. At the same time, the main shaft 22 drives the second leaf plate 25 to continuously rub against the outer surface of the non-woven fabric. The second leaf plate 25 squeezes the surface of the non-woven fabric. Through the rotation of the main shaft 22, the second leaf plate 25 intermittently squeezes and impacts the outer surface of the non-woven fabric, vibrating the dust out of the non-woven fabric. Each of the two leaf plates 25 has multiple oblique protrusions 26 fixedly installed at its top end, and multiple compression rods 24 are provided at the end of each of the two leaf plates 25. By rotating the main shaft 22, the oblique protrusions 26 at the top of the two leaf plates 25 are adjusted to squeeze the non-woven fabric. At the same time, the two leaf plates 25 are subjected to force and can slide inside the first leaf plate 23. The two leaf plates 25 slide into the first leaf plate 23, squeezing the two compression rods 24 to compress the fabric. At the same time, the compression rods 24 exert a thrust on the two leaf plates 25 in the opposite direction, so that the two leaf plates 25 are always in contact with the non-woven fabric. Each connecting sleeve 27 has two limiting blocks 28 on its surface. Each limiting block 28 has an elastic rod 29 fixedly installed at its end. The end of each elastic rod 29 is connected to the inside of the dust housing 11. By continuously rotating the main shaft 22, the main shaft 22 drives the connecting sleeve 27 to rotate inside the dust housing 11. The rotating connecting sleeve 27 squeezes the two limiting blocks 28. The limiting blocks 28 are squeezed by the connecting sleeve 27. The two limiting blocks 28 slide symmetrically, squeezing the elastic rod 29 at their ends. At the same time, after the elastic rod 29 is compressed, it continues to push the limiting block 28 to rub against the connecting sleeve 27. The same dust collection box 13 is fixedly installed at the side ends of both connecting pipes 12. A filter screen 14 is fixedly installed inside the dust collection box 13. Both connecting pipes 12 are connected to the dust collection box 13. The dust collection box 13 has a hollow structure. By creating a negative pressure zone inside the dust collection box 13, the air inside the dust shell 11 is drawn into the dust collection box 13 through the connecting pipes 12. Due to the squeezing and impact of the non-woven fabric by the cooperation of the first plate 23 and the second plate 25, not only is dust cleaned, but also a large amount of short fiber debris is removed. Through the air flow, the air carries the dust and short fiber debris into the interior of the dust collection box 13. A filter screen 14 is installed inside the dust collection box 13. The filter screen 14 intercepts the short fiber debris and collects it for reuse, reducing material waste. A backplate interface 15 is fixedly installed on the side end of the dust collection box 13. A pipe is fixedly installed on the surface of the backplate interface 15. The end of the pipe is connected to a vacuum pump. By starting the pump, a negative pressure zone is generated inside the backplate interface 15. The air inside the dust housing 11 is transported to the inside of the dust collection box 13 through the connecting pipe 12. Each dust housing 11 has two fixed seats 18 at its side end, and each fixed seat 18 has a guide rod 21 at its side end. The same electric push rod 19 is provided on the inner side of both fixed seats 18. By driving the electric push rod 19, both ends of the electric push rod 19 exert force on the fixed seat 18, causing the fixed seat 18 to contract between the guide rods 21. The electric push rod 19 pulls the fixed seat 18 to slide symmetrically, and the fixed seat 18 drives the guide rods 21 to move. The guide rods 21 are inserted into the interior of the fixed seat 18 respectively, and the guide rods 21 increase the guiding capacity. At the same time, the two fixed seats 18 drive the dust housing 11 to move, so that the dust housing 11 is pressed against the surface of the non-woven fabric. Multiple guide strips 16 are distributed at an angle inside each dust housing 11. As the air carries dust and short fiber debris, the guide strips 16 guide the airflow in a directional manner, forming an orderly directional flow that concentrates and guides the dust and short fiber debris to the inlet area of ​​the connecting pipe 12. At the same time, the structure of the guide strips 16 performs preliminary sorting and separation of large dust particles and accumulated short fiber debris in the air. Each second page plate 25 is guided and slidably connected inside the first page plate 23. Each first page plate 23 is provided with a sliding groove that is adapted to the second page plate 25, and the second page plate 25 can slide along the sliding groove inside the first page plate 23. At the same time, one end of each of the multiple compression rods 24 at the end of the second page plate 25 is connected to the second page plate 25, and the other end is connected to the inner side of the first page plate 23.

[0015] Example 2 This embodiment specifically discloses the working process of an environmentally friendly dust removal device for nonwoven fabric production as described in Embodiment 1 above, including the following steps: The first step is to place the non-woven fabric between the two dust housings 11 and drive the electric push rod 19. The fixed seats 18 at both ends of the push rod 19 slide symmetrically along the guide rod 21, causing the two dust housings 11 to close together. During the closing process, the rubber pad strip 17 on the inner side of the dust housing 11 is subjected to force and undergoes bending deformation, which tightly adheres to the surface of the non-woven fabric, thereby ensuring the sealing of the inside of the dust housing 11 and preventing dust from leaking out during the dust removal process.

[0016] The friction between the second page plate 25 and the outer surface of the nonwoven fabric drives the main shaft 22 to rotate inside the dust housing 11. As the main shaft 22 rotates, it causes the second page plate 25 to continuously "rub against and intermittently squeeze and impact" the outer surface of the nonwoven fabric, shaking out the dust inside the nonwoven fabric. The oblique protrusion 26 at the top of the second page plate 25 further squeezes the nonwoven fabric, enhancing the dust shaking effect. At the same time, after being subjected to force, the second page plate 25 slides inside the first page plate 23, squeezing the compression rod 24 to compress it. The reverse thrust of the compression rod 24 ensures that the second page plate 25 is always in close contact with the nonwoven fabric, maintaining the continuity of dust removal. The connecting sleeves 27 at both ends of the main shaft 22 rotate with it. The positioning grooves on the surface of the connecting sleeves 27 squeeze the limiting blocks 28, causing the two limiting blocks 28 to slide symmetrically and squeeze the elastic rod 29. After being compressed, the elastic rod 29 pushes the limiting blocks 28 in the opposite direction, causing them to continuously rub and collide with the connecting sleeves 27, strengthening the rotational vibration effect of the main shaft 22, and facilitating the shaking out of dust.

[0017] The second step is to start the vacuum pump connected to the back panel interface 15 to form a negative pressure zone inside the dust collection box 13. The dust and short fiber debris shaken out of the dust housing 11 are sucked into the dust collection box 13 along with the air through the connecting pipe 12. The short fiber debris carried by the air is intercepted by the filter screen 14 inside the dust collection box 13, realizing the recycling of short fibers and reducing material waste. The filtered air is then discharged through the subsequent path.

[0018] This utility model has been described with reference to the above-described embodiments and accompanying drawings. However, the above embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. On the contrary, modifications and equivalent provisions included in the spirit and scope of the claims are all included within the scope of this utility model.
