Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a dust removal device for hot air nonwoven fabric production. Background Technology

[0002] The origin of nonwoven fabrics can be traced back to ancient China. Ancient nomadic peoples mixed animal hair with water, urine, or milk essence and used mechanical actions such as stepping and beating to make felt. This was the earliest prototype of nonwoven materials. Since the 1990s, nonwoven fabric technology has developed into dozens of production processes, represented by hydroentangling, meltblown, spunbond, and composite. Its application fields have continued to expand, covering many fields such as medical, hygiene, home decoration, clothing, industry, and agriculture.

[0003] In the existing technology, some fiber debris and dust may be generated during the subsequent processing of nonwoven fabrics, such as hot rolling, slitting, and winding. Dust removal devices can effectively collect these debris and dust. However, in use, the existing dust removal devices are inefficient and cannot perform comprehensive dust removal. Furthermore, the dust removal devices cannot effectively capture and filter dust of different sizes, reducing the filtration effect of the filter screen.

[0004] Therefore, a dust removal device for hot air nonwoven fabric production was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal device for hot air nonwoven fabric production, which solves the technical problems of existing dust removal devices having low efficiency in the dust removal process, being unable to perform comprehensive dust removal, and being unable to effectively capture and filter dust of different sizes, thus reducing the filtration effect of the filter screen. It achieves the purpose of vibration dust removal and dust suction filtration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for hot air nonwoven fabric production, comprising a dust removal box, a cabinet door movably installed on the front of the dust removal box, support legs fixedly installed at equal intervals on both sides of the bottom of the dust removal box, fabric arranged inside the dust removal box, a vibration dust removal component arranged on the back of the dust removal box, and a dust suction and filtration component arranged inside the dust removal box.

[0007] Preferably, the vibration dust removal assembly specifically includes: a rotating rod, which is equidistantly and uniformly rotatably connected to the inner wall surface of the dust removal box; a limiting sleeve, which is equidistantly and fixedly sleeved on the outer wall of the rotating rod; a cross groove, which is connected and opened on the back of the dust removal box; and a mounting plate, which is fixedly installed on the back of the dust removal box.

[0008] Preferably, the outer wall of the rotating rod is in contact with the surface of the fabric, the inner wall of the cross groove is equidistantly connected with cross blocks, a connecting rod is fixedly installed on one side of the cross block, a dust-removing rod is fixedly installed on the other end of the connecting rod, the surface of the dust-removing rod is in contact with the surface of the fabric, and a spring is fixedly installed equidistantly between the surface of the cross block and the inner wall of the cross groove.

[0009] Preferably, a drive cylinder is fixedly installed on the other side of the cross block, a motor is fixedly installed on the surface of the mounting plate, a rotating shaft is fixedly installed at the output end of the motor, and a cam is fixedly installed at the other end of the rotating shaft. The outer wall of the cam contacts the outer wall of the drive cylinder. The cam is driven to rotate by the motor, and the cam pushes the drive cylinder, thereby causing the cross block to slide in the cross groove, which drives the dust removal rod to vibrate and remove dust from the fabric. This can effectively remove dust adhering to the surface of the non-woven fabric. Compared with simple vacuuming, it can greatly improve dust removal efficiency and also has a good cleaning effect on some tightly adhered dust, thus achieving the effect of vibration dust removal.

[0010] Preferably, the dust collection and filtration assembly specifically includes: a dust collection pipe, which is connected and installed on both sides of the dust collection box; and an exhaust fan, which is fixedly installed between the inner walls of the dust collection pipe.

[0011] Preferably, magnets are fixedly installed at equal intervals on both sides of the suction tube, and connecting frames are connected at equal intervals between the inner walls of the suction tube. The top of the connecting frame extends through the top of the inner wall of the suction tube and extends to the top of the suction tube.

[0012] Preferably, the top of the vacuum tube is provided with sealing plates at equal intervals, the top of the sealing plate is fixedly installed with a handle, the bottom of the sealing plate is fixedly connected to the top of the connecting frame, and magnets are fixedly installed on both sides of the sealing plate, with the bottom of the magnets attracting the top of the magnets.

[0013] Preferably, an electrostatic generator is fixedly installed on the top of the inner wall of the suction pipe. A connecting frame two is snapped between the inner walls of the suction pipe. Dust collection plates are fixedly installed at equal intervals between the inner walls of the connecting frame two. The top of the connecting frame two movably passes through the top of the inner wall of the suction pipe and extends to the top of the suction pipe, where it is fixedly connected to the bottom of the sealing plate. It is connected to both sides of the dust collection box via the suction pipe, and an exhaust fan is installed inside. This fan can create a strong negative pressure inside the dust collection box, quickly sucking the dust that has been shaken down into the suction pipe, preventing the dust from flying again inside the dust collection box, ensuring a clean dust collection environment, and further improving the dust collection effect. Magnets one are fixedly installed at equal intervals on both sides of the suction pipe, working in conjunction with magnets two on the connecting frame one and the sealing plate, so that when not needed... With the aid of tools, the connecting frame and the suction tube can be easily engaged and disengaged, facilitating cleaning and maintenance of the suction tube's interior. Magnetic adsorption ensures connection stability and guarantees proper suction. An electrostatic generator is fixedly installed on the top of the inner wall of the suction tube, charging dust particles and attracting them to the dust collection plate. Utilizing electrostatic adsorption, this significantly improves the capture of fine dust particles, enhancing dust removal precision and resulting in cleaner exhaust air, reducing environmental pollution and benefiting the subsequent production quality of non-woven fabrics. Pulling the handle allows for easy removal of the connecting frame and dust collection plate from the suction tube, facilitating the cleaning of dust adsorbed on the plate and achieving the desired dust filtration effect.

[0014] This utility model provides a dust removal device for hot air nonwoven fabric production. It has the following beneficial effects:

[0015] (1) This utility model can remove dust from both sides of the fabric by setting a vibration dust removal component. The fabric can be guided by the rotating rod and the limiting sleeve can prevent the fabric from shifting. The starting motor drives the rotating shaft and cam to rotate. The cam rotation pushes the driving cylinders on both sides back and forth. The driving cylinder drives the cross block, connecting rod and dust removal rod to move. The cross block compresses the spring. When the driving cylinder contacts the circular surface of the cam, the spring releases the stored energy. Finally, the dust removal rod knocks on the surface of the fabric, which can greatly improve the dust removal efficiency and also has a good cleaning effect on some tightly attached dust, thus achieving the effect of vibration dust removal.

[0016] (2) This utility model can collect dust by setting up a dust collection and filtration component. When the exhaust fan is turned on, the dust raised by the vibration enters the dust collection pipe. Then, the electrostatic generator is powered on to generate static electricity on the dust collection surface. Then, the dust with static electricity is adsorbed by the dust collection plate. Then, it is deeply filtered by three layers of filter screens, reducing the burden on each filter screen. By using the principle of electrostatic adsorption, the ability to capture small dust particles is greatly improved, the accuracy of dust removal is improved, and the exhaust air is cleaner, thereby achieving the effect of dust collection and filtration.

[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] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] The existing dust removal devices suffer from low efficiency, inability to effectively remove dust comprehensively, and failure to effectively capture and filter dust particles of different sizes, thus reducing the filtration effect of the filter screen. Therefore, this invention provides a preferred embodiment of a hot air nonwoven fabric production dust removal device, for example... Figure 1-4As shown: A dust removal device for hot air nonwoven fabric production includes a dust removal box 1, a cabinet door 2 movably installed on the front of the dust removal box 1, support legs 3 fixedly installed at equal intervals on both sides of the bottom of the dust removal box 1, a cloth 4 inside the dust removal box 1, a vibration dust removal component 5 on the back of the dust removal box 1, and a dust suction and filter component 6 inside the dust removal box 1.

[0025] The vibration dust removal assembly 5 specifically includes: a rotating rod 511, which is equidistantly and uniformly rotatably connected to the inner wall surface of the dust removal box 1; a limiting sleeve 512, which is equidistantly and fixedly sleeved on the outer wall of the rotating rod 511; a cross groove 513, which is connected and opened on the back of the dust removal box 1; and a mounting plate 519, which is fixedly installed on the back of the dust removal box 1.

[0026] The outer wall of the rotating rod 511 is in contact with the surface of the fabric 4. The inner wall of the cross groove 513 is equidistantly connected with a cross block 514. A connecting rod 515 is fixedly installed on one side of the cross block 514. A dust-removing rod 516 is fixedly installed on the other end of the connecting rod 515. The surface of the dust-removing rod 516 is in contact with the surface of the fabric 4. A spring 517 is fixedly installed equidistantly between the surface of the cross block 514 and the inner wall of the cross groove 513.

[0027] A drive cylinder 518 is fixedly installed on the other side of the cross block 514. A motor 5111 is fixedly installed on the surface of the mounting plate 519. A rotating shaft is fixedly installed at the output end of the motor 5111. A cam 5112 is fixedly installed at the other end of the rotating shaft. The outer wall of the cam 5112 is in contact with the outer wall of the drive cylinder 518.

[0028] In this example, the vibration dust removal component 5 can remove dust from both sides of the fabric 4. The rotating rod 511 can guide the fabric 4, and the limiting sleeve 512 can prevent the fabric 4 from shifting. The starting motor 5111 drives the rotating shaft and cam 5112 to rotate. The rotation of the cam 5112 pushes the driving cylinders 518 on both sides back and forth. The driving cylinders 518 drive the cross block 514, connecting rod 515, and dust removal rod 516 to move. The cross block 514 compresses the spring 517. When the driving cylinder 518 contacts the circular surface of the cam 5112, the spring 517 releases its stored energy. Finally, the dust removal rod 516 drives the dust removal rod to tap the surface of the fabric 4, thereby achieving the effect of vibration dust removal. Example

[0029] Based on Embodiment 1, a preferred embodiment of the hot air nonwoven fabric production dust removal device provided by this utility model is as follows: Figure 1-4 As shown: The dust collection and filtration assembly 6 specifically includes: a dust collection pipe 611, which is connected and installed on both sides of the dust collection box 1; and an exhaust fan 612, which is fixedly installed between the inner walls of the dust collection pipe 611.

[0030] Magnets 613 are fixedly installed at equal intervals on both sides of the suction pipe 611. A connecting frame 614 is connected at equal intervals between the inner walls of the suction pipe 611. The top of the connecting frame 614 moves through the top of the inner wall of the suction pipe 611 and extends to the top of the suction pipe 611.

[0031] The top of the suction pipe 611 is evenly spaced with sealing plates 616. A handle 617 is fixedly installed on the top of the sealing plate 616. The bottom of the sealing plate 616 is fixedly connected to the top of the connecting frame 614. Magnets 618 are fixedly installed on both sides of the sealing plate 616. The bottom of the magnets 618 is attracted to the top of the magnets 613.

[0032] An electrostatic generator 619 is fixedly installed on the top of the inner wall of the suction pipe 611. A connecting frame 6111 is snapped between the inner walls of the suction pipe 611. Dust collection plates 6112 are fixedly installed at equal intervals between the inner walls of the connecting frame 6111. The top of the connecting frame 6111 moves through the top of the inner wall of the suction pipe 611 and extends to the top of the suction pipe 611, where it is fixedly connected to the bottom of the sealing plate 616.

[0033] In this example, dust can be collected by setting up the dust collection and filtration assembly 6. The exhaust fan 612 is started and the dust raised by the vibration enters the dust collection pipe 611. Then, the electrostatic generator 619 is energized to generate static electricity on the dust collection surface. The dust with static electricity is then adsorbed by the dust collection plate 6112 and then deeply filtered through three layers of filter screens to reduce the burden on each filter screen, thereby achieving the function of dust collection and filtration.

[0034] Working principle: First, the cloth 4 enters from the top of the dust collection box 1 and then exits from the side of the dust collection box 1. The cloth 4 is guided by the rotating rod 511, and the limiting sleeve 512 prevents the cloth 4 from deviating. When it is necessary to remove dust from the surface of the cloth 4, the motor 5111 is started to drive the rotating shaft and cam 5112 to rotate. The rotation of the cam 5112 pushes the driving cylinders 518 on both sides back and forth. The driving cylinders 518 drive the cross block 514 and the connecting rod 5 15. The dust-dispelling rod 516 moves, and the cross block 514 compresses the spring 517. When the driving cylinder 518 contacts the circular surface of the cam 5112, the spring 517 releases its stored energy, finally driving the dust-dispelling rod 516 to tap the surface of the fabric 4. This causes the dust-dispelling rod 516 to tap the surface of the fabric 4 back and forth, raising dust. When dust collection is needed, the exhaust fan 612 is activated, and the dust raised by the vibration enters the suction pipe 611, and then... When the electrostatic generator 619 is energized, it generates static electricity on the incoming dust removal surface. The dust collected by the static electricity is then adsorbed by the dust collection plate 6112. The dust collection plate 6112 is made of conductive metal material and is connected to the other pole of the electrostatic generator 619, forming a polarity opposite to the discharge electrode. Then, deep filtration is performed through three layers of filter screens to reduce the burden on each filter screen. The first layer is a coarse filter screen, which intercepts large dust particles. The second layer is an activated carbon filter screen, which adsorbs small particles and odors. The third layer is a fine filter screen for fine filtration. When it is necessary to clean the filter screen 615 and the dust collection plate 6112, the handle 617 drives the sealing plate 616 upward, which then drives the connecting frame 614 and the connecting frame 6111 out of the suction pipe 611. The magnet 618 separates from the magnet 613, and then the filter screen 615 and the dust collection plate 6112 can be cleaned, thereby achieving the functions of vibration dust removal and dust suction filtration.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
