Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric production, and more specifically, to a dust removal device and a dust removal method for non-woven fabric production. Background Art

[0002] Non-woven fabric is a non-woven fabric produced from polyester fiber and polyester fiber materials, formed by hydroentangling, needling, or hot rolling reinforcement, and finally finished through post-treatment; currently, after non-woven fabric production, winding work is required to facilitate later handling. During the processing, there will be flocs adhering to the surface of the non-woven fabric. In addition, the dust floating in the production workshop on the non-woven fabric results in a certain amount of dust impurities on the wound non-woven fabric, thus affecting the quality of the non-woven fabric.

[0003] For example, a winding device for non-woven fabric disclosed in the patent with the patent number CN113415660B can perform dust removal treatment on the non-woven fabric during winding and collect the sucked dust. However, the suction force generated by the rotation of the suction fan blades is used to suck the dust in the curling cavity into the dust removal cavity, resulting in poor removal effects of the flocs and dust adhering to the non-woven fabric, so it needs to be improved.

For the dust removal device for non-woven fabric production, through the settings of the clamping roller assembly, pressing roller assembly, swing mechanism and lifting mechanism, the lifting mechanism drives the pressing roller assembly to move upward, so that the non-woven fabric in the dust removal cavity is relaxed. At this time, the swing mechanism drives the clamping roller assembly to swing reciprocally, so that the non-woven fabric generates a wavy swing, thereby preferably realizing the shaking off of the debris and dust on the non-woven fabric, that is, realizing the removal of debris and dust on the non-woven fabric.

[0026] 2. For the dust removal device for non-woven fabric production, through the setting of the suction mechanism, the swing mechanism can drive the suction assembly to suck out the debris and dust floating in the dust removal cavity, preventing it from falling onto the non-woven fabric again, so that the dust removal effect of the dust removal box on the debris and dust on the non-woven fabric is better.

[0041] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention rather than limiting it.

[0042] The following is further described in detail in conjunction with the attached Figures 1 - 7 This embodiment is further described in detail.

[0043] Combined with Figures 1 - 3 As shown, a dust removal device for non-woven fabric production in this embodiment includes a dust removal box 100. A cavity is provided inside the dust removal box 100, and a partition 200 is provided inside the cavity for separating the cavity into a dust removal cavity 201 in the middle and drive cavities 202 on both sides.

[0044] Clamping roller assemblies 210 for clamping the non-woven fabric 300 are oppositely provided at the front and rear sides inside the dust removal cavity 201. A pressing roller assembly 220 for pressing the non-woven fabric 300 is provided below inside the dust removal cavity 201. A lifting mechanism for driving the pressing roller assembly 220 to lift is provided inside the drive cavity 202. A swinging mechanism for driving the clamping roller assemblies 210 to swing relatively is further provided inside the drive cavity 202. A suction mechanism 230 is provided inside the drive cavity 202, and the swinging mechanism is used to drive the suction mechanism 230 to suck out the dust inside the dust removal cavity 201.

[0045] The dust removal device for non-woven fabric production in this embodiment is used to remove the residual debris and dust on the non-woven fabric 300. During actual use, notch openings 101 corresponding to the dust removal cavity 201 are provided on the front and rear side surfaces of the dust removal box 100. The non-woven fabric 300 enters from the notch opening 101 on the front side, passes through the clamping roller assemblies 210, the pressing roller assembly 220, and the clamping roller assemblies 210 in sequence, and then is discharged out of the dust removal box 100 from the notch opening 101 on the rear side. During actual use, the non-woven fabric 300 discharged from the notch opening 101 on the rear side can be connected to an existing winding device, and the winding device is used to wind the non-woven fabric 300, which can realize the movement of the non-woven fabric 300 inside the dust removal cavity 201, thereby realizing continuous dust removal of the non-woven fabric 300.

[0046] In this embodiment, through the settings of the lifting mechanism and the swinging mechanism, the lifting mechanism can drive the pressing roller assembly 220 to lift. When the pressing roller assembly 220 moves downward, it can further tighten the non-woven fabric 300 passing through the dust removal cavity 201, so as to facilitate the movement of the non-woven fabric 300 under the action of the winding device. During this process, the swinging mechanism stops driving the clamping roller assemblies 210 to swing.

[0047] When the pressing roller assembly 220 moves upward, the non-woven fabric 300 between the clamping roller assembly 210 and the pressing roller assembly 220 can be relaxed. At this time, the swing mechanism can drive the clamping roller assembly 210 to swing reciprocally, so that the non-woven fabric 300 can swing in a wavy shape and move toward the pressing roller assembly 220 at the clamping roller assembly 210, thereby preferably shaking off the debris and dust on the non-woven fabric 300 and making it float in the dust removal chamber 201. Thus, the removal of debris and dust on the non-woven fabric 300 is preferably achieved;

[0048] Among them, through the setting of the suction mechanism 230, the swing mechanism can drive the suction mechanism 230 to suck out the floating debris and dust in the dust removal chamber 201, preventing the floating debris and dust from falling back onto the non-woven fabric 300 again. Thus, the dust removal effect of the dust removal box 100 on the non-woven fabric 300 is better;

[0049] In actual use of this embodiment, the winding device can wind the non-woven fabric 300 at intervals. That is, after the dust removal box 100 performs the dust removal operation on a section of the non-woven fabric 300, the winding device pulls the non-woven fabric 300 to move, so that another section of the non-woven fabric 300 to be dusted enters the dust removal box 100 for the dust removal operation. Thus, the continuous dust removal of the non-woven fabric 300 is preferably achieved;

[0050] Combined Figure 4 and Figure 5 As shown, in this embodiment, the clamping roller assembly 210 includes oppositely arranged mounting plates 311. A clamping roller 312 for clamping the non-woven fabric 300 is arranged between the mounting plates 311. A cross-shaped swing plate is arranged on the mutually remote sides of the mounting plates 311. The swing plate includes a first long block 510 arranged along the length direction of the mounting plate 311 and a second long block 520 arranged perpendicular to the mounting plate 311. A driving groove 521 is arranged on the second long block 520, and moving grooves 511 are arranged on the upper and lower sides of the first long block 510;

[0051] The swing mechanism includes mounting bottom plates 530 fixedly installed on the left and right side walls of the dust removal chamber 201. Guide wheels 531 moving in the moving grooves 511 are arranged on the mounting bottom plates 530. A rotatable driving shaft 540 is arranged on the mounting bottom plates 530. One end of the driving shaft 540 is provided with a driving column 532 sliding in the driving groove 521 through a long rod.

[0052] In actual use of this embodiment, as Figure 3 shown, the mounting plates 311 located on the front and rear sides of the dust removal box 100 are arranged obliquely relative to each other and are perpendicular to the non-woven fabric 300 passing between the corresponding clamping roller assembly 210 and the pressing roller assembly 220. Thus, the swing mechanism drives the clamping roller assembly 210 to swing reciprocally along the extending direction of the mounting plate 311, which can preferably make the non-woven fabric 300 swing in a wavy shape;

[0053] Among them, the driving groove 521 is arranged along the extending direction of the second long strip 520, and the moving groove 511 is arranged along the extending direction of the first long strip 510. Thus, the guiding wheel 531 is rotatably installed in the corresponding moving groove 511, and the sliding installation of the mounting plate 311 and the swing plate on the mounting bottom plate 530 can be preferably realized. Among them, the mounting bottom plate 530 is fixedly installed on the left and right side walls of the dust removal chamber 201 through bolts (that is, the mounting bottom plate 530 is fixed on the corresponding partition plate 200). Thus, the swing installation of the clamping roller 312 in the dust removal chamber 201 can be preferably realized, so as to make the non-woven fabric 300 swing in a wavy shape;

[0054] Among them, through the arrangement of the driving shaft 540, the long rod and the driving column 532, the driving column 532 can slide in the driving groove 521, and the driving shaft 540 rotates to drive the long rod to make the driving column 532 reciprocate in the driving groove 521. Furthermore, the clamping of the non-woven fabric 300 by the clamping roller 312 and the reciprocating swing on the mounting bottom plate 530 are preferably realized, so as to preferably make the non-woven fabric 300 swing in a wavy shape, so as to shake off the debris and dust on the non-woven fabric 300.

[0055] Combined Figure 6 As shown, in this embodiment, the swing mechanism further includes a driving component for driving the driving shaft 540 to rotate. The driving component includes a mounting box 240. A rotatable first rotating rod 241 is provided above the mounting box 240. A first sprocket 242 is provided on the first rotating rod 241. The driving shafts 540 on the front and rear sides both extend into the corresponding driving chambers 202. Second sprockets 541 are provided at the ends of the driving shafts 540 extending into the driving chambers 202. A chain 411 is sleeved between the first sprocket 242 and the second sprocket 541; A driving member for driving the first rotating rod 241 to rotate is further provided in the mounting box 240.

[0056] When this embodiment is actually used, the mounting box 240 is fixedly installed on the side wall of the driving chamber 202 through bolts, and a cavity with an opening facing upward is arranged therein. The first rotating rod 241 is rotatably installed above the cavity through a bearing. Among them, through the arrangement of the first sprocket 242, the second sprocket 541 and the chain 411, the rotation of the first rotating rod 241 can drive the driving shaft 540 to rotate synchronously, that is, the swing of the clamping roller assembly 210 is realized;

[0057] Among them, through the arrangement of the driving member, it can drive the first rotating rod 241 to rotate.

[0058] In this embodiment, the driving member includes a second rotating rod 250 rotatably disposed in the mounting box 240. A first bevel gear 251 is provided on the second rotating rod 250, and a second bevel gear 243 mating with the first bevel gear 251 is provided on the first rotating rod 241. A rotatable third rotating rod 260 is provided at the bottom end in the mounting box 240, and the upper end of the third rotating rod 260 and the lower end of the second rotating rod 250 are connected by a clutch assembly.

[0059] In actual use of this embodiment, the second rotating rod 250 is rotatably disposed in the cavity in the up and down direction. Through the cooperation of the first bevel gear 251 and the second bevel gear 243, the rotation of the second rotating rod 250 can drive the rotation of the first rotating rod 241.

[0060] Among them, the third rotating rod 260 is also rotatably disposed in the cavity in the up and down direction. In actual use, a double-shaft motor 262 for driving the third rotating rod 260 to rotate is provided on the bottom wall of the mounting box 240. The double-shaft motor 262 can preferably drive the reciprocating swing of the clamping roller assembly 210.

[0061] Among them, through the setting of the clutch assembly, the transmission cooperation between the third rotating rod 260 and the second rotating rod 250 can be controlled, that is, whether the clamping roller assembly 210 reciprocates can be controlled through the clutch assembly.

[0062] Combined with Figure 4 As shown, in this embodiment, the pressing roller assembly 220 includes a bracket 221, and a rotatable pressing roller 222 is provided between the brackets 221. The brackets 221 are fixedly connected to a lifting plate 223.

[0063] The lifting mechanism includes a top plate 270 provided at the bottom in the mounting box 240. The top plate 270 is connected to the corresponding end of the lifting plate 223 through a folding plate 632. A cylinder 420 for driving the top plate 270 to lift is installed on the bottom wall of the mounting box 240.

[0064] In actual use of this embodiment, notches for the corresponding folding plates 632 to pass through are provided on both the mounting box 240 and the partition plate 200. Thus, the folding plate 632 can preferably connect the top plate 270 and the lifting plate 223. Among them, through the setting of the cylinder 420, it can drive the top plate 270 to lift in the mounting box 240, and then drive the lifting plate 223 to drive the bracket 221 to lift, so as to realize the lifting of the pressing roller assembly 220.

[0065] Among them, in order to make the top plate 270 lift smoothly in the mounting box 240, two cylinders 420 are oppositely arranged on both sides of the bottom wall of the mounting box 240.

[0066] Combined with Figure 6As shown in the figure, in this embodiment, the clutch assembly includes an upper clutch cylinder 252 sleeved on the lower end of the second rotating rod 250 in a liftable manner. The lower end wall of the upper clutch cylinder 252 is evenly provided with lower ratchet teeth 611 along its circumferential direction; a lower clutch cylinder 261 is sleeved on the upper end of the third rotating rod 260 in a liftable manner. The upper end wall of the lower clutch cylinder 261 is evenly provided with upper ratchet teeth 621 meshing with the lower ratchet teeth 611 along its circumferential direction. On the top plate 270 and opposite to both sides of the third rotating rod 260, there are push rods 631 for jacking up the lower clutch cylinder 261 to realize the cooperation between the upper ratchet teeth 621 and the lower ratchet teeth 611.

[0067] In actual use of this embodiment, the upper clutch cylinder 252 and the second rotating rod 250 are in keyway fit, whereby the upper clutch cylinder 252 and the second rotating rod 250 rotate synchronously preferably; wherein, the lower clutch cylinder 261 and the third rotating rod 260 are in keyway fit, whereby the lower clutch cylinder 261 and the third rotating rod 260 rotate synchronously.

[0068] Among them, through the arrangement of the push rod 631, when the cylinder 420 drives the top plate 270 to drive the pressing roller assembly 220 to move upward, the push rod 631 can be driven to move upward, and then the lower clutch cylinder 261 is jacked up so that the upper ratchet teeth 621 on it extend into the lower ratchet teeth 611, thereby preferably realizing the mutual meshing between the two. That is, when the pressing roller assembly 220 moves upward to make the non-woven fabric 300 loose, the clutch assembly can be driven to cooperate, so that the dual-axis motor 262 can drive the swing mechanism to drive the clamping roller assembly 210 to swing reciprocally; when the pressing roller assembly 220 moves downward, the push rod 631 can be driven to move downward, so that the lower clutch cylinder 261 moves downward due to its own weight, and then the cooperation between the clutch assemblies is released, so that the swing mechanism stops driving the clamping roller assembly 210 to swing, thereby facilitating the movement of the non-woven fabric 300.

[0069] Among them, as Figure 6 shown, in order to preferably realize the cooperation between the upper ratchet teeth 621 and the lower ratchet teeth 611 during rotation, the third rotating rod 260 only rotates in the same direction under the action of the dual-axis motor 262. Thus, when the upper ratchet teeth 621 and the lower ratchet teeth 611 mesh with each other, the second rotating rod 250 and the third rotating rod 260 can rotate synchronously.

[0070] Among them, in order to prevent the lower clutch cylinder 261 from moving upward under the action of the ejector rod 631 and causing damage to the upper ratchet 621 and the lower ratchet 611 due to the rigid fit between the upper ratchet 621 and the lower ratchet 611 during the meshing process of the upper ratchet 621 and the lower ratchet 611, the upper clutch cylinder 252 is vertically movably arranged on the second rotating rod 250. During actual use, the lower end of the second rotating rod 250 extends into the upper clutch cylinder 252, and a retaining ring is threadedly connected to the lower end of the second rotating rod 250. A spring mounting ring 641 is further arranged outside the second rotating rod 250, and a spring 642 for driving the upper clutch cylinder 252 to move downward is sleeved outside the second rotating rod 250. The upper end of the spring 642 abuts against the spring mounting ring 641, and the lower end abuts against the upper end wall of the upper clutch cylinder 252. Due to the arrangement of the retaining ring, it is preferably to prevent the spring 642 from driving the upper clutch cylinder 252 to disengage from the second rotating rod 250. The lifting of the upper clutch cylinder 252 can be realized by using the spring 642, so that when the lower clutch cylinder 261 moves upward and impacts the upper clutch cylinder 252, the upper clutch cylinder 252 can move upward, thereby realizing the flexible connection between the two. At the same time, the spring 642 can finally drive the upper clutch cylinder 252 to move downward to realize the meshing between the upper ratchet 621 and the lower ratchet 611;

[0071] During actual use, the upper end of the third rotating rod 260 extends into the upper clutch cylinder 252, and during the lifting process of the upper clutch cylinder 252, the upper end of the third rotating rod 260 does not disengage from the upper clutch cylinder 252. Thus, the rotation of the third rotating rod 260 is made more stable;

[0072] Combined Figure 7 As shown in the figure, in this embodiment, the suction mechanism 230 includes an air duct 231 arranged in the drive chamber 202 and having one end communicating with the dust removal chamber 201. The other end of the air duct 231 extends outside the dust removal box 100. A rotatable rotating shaft 233 is arranged in the air duct 231 through a circular ring frame 232. A fan blade 234 is arranged at one end of the rotating shaft 233, and a third bevel gear 235 is arranged at the other end of the rotating shaft 233;

[0073] A fourth rotating rod 280 that is rotatable and has its upper end extending into the air duct 231 is further arranged in the drive chamber 202. A fourth bevel gear 281 that meshes with the third bevel gear 235 is arranged at the upper end of the fourth rotating rod 280. Pulley wheels are arranged between the lower end of the third rotating rod 260 and the lower end of the fourth rotating rod 280, and the pulley wheels are connected by a belt.

[0074] During actual use of this embodiment, one end of the air duct 231 extending outside the dust removal box 100 is connected to an existing processing device, such as a bag filter, thereby realizing the treatment of the discharged gas for its emission;

[0075] Among them, the circular ring frame 232 is installed in the air duct 231 by means of threads, and there are two of them arranged oppositely. The rotating shaft 233 is horizontally rotatably installed between the circular ring frames 232 through bearings. Through the arrangement of the fan blades 234, the rotation of the rotating shaft 233 drives the fan blades 234 to rotate, thereby sucking the gas in the dust removal chamber 201 into the air duct 231. Thus, the floating debris and dust in the dust removal chamber 201 are sucked and discharged;

[0076] Among them, the fourth rotating rod 280 is rotatably installed in the driving chamber 202 through a bearing in the up-and-down direction. Through the arrangement of the third bevel gear 235 and the fourth bevel gear 281, the rotation of the fourth rotating rod 280 can drive the rotating shaft 233 to rotate. Through the arrangement of the belt pulley and the belt, the rotation of the third rotating rod 260 can drive the fourth rotating rod 280 to rotate, so that the double-shaft motor 262 can always drive the fan blades 234 to rotate, sucking the gas in the dust removal chamber 201 into the air duct 231 and discharging it, thereby improving the dust removal effect of the dust removal box 100 on the non-woven fabric 300.

[0077] This embodiment also provides a non-woven fabric dust removal method, which uses the above-mentioned dust removal device for non-woven fabric production, and specifically includes the following steps:

[0078] S1. Insert the non-woven fabric 300 to be dusted into the dust removal chamber 201 from the front slot 101, pass through the clamping rollers 312, the pressing roller 222 and the clamping rollers 312 in sequence, and then extend out from the rear slot 101 and be connected to the winding device;

[0079] S2. Start the double-shaft motor 262 to drive the third rotating rod 260 to rotate, and then drive the fourth rotating rod 280 to rotate to drive the fan blades 234 to suck the gas in the dust removal chamber 201 into the air duct 231;

[0080] S3. Drive the pressing roller 222 to move upward through the air cylinder 420 to loosen the non-woven fabric 300. At the same time, drive the lower clutch cylinder 261 to move upward so that the upper ratchet tooth 621 and the lower ratchet tooth 611 are engaged, so that the third rotating rod 260 can drive the second rotating rod 250 to rotate, and then the swing mechanism drives the corresponding clamping rollers 312 to swing reciprocally, causing the non-woven fabric 300 to swing in a wavy shape and shaking off the debris and dust on it;

[0081] S4. After the non-woven fabric 300 finishes swinging, drive the pressing roller 222 to move downward through the air cylinder 420, drive the lower clutch cylinder 261 to move downward, release the engagement between the upper ratchet tooth 621 and the lower ratchet tooth 611, and then the swing mechanism stops driving the clamping rollers 312 to swing reciprocally, and then the non-woven fabric 300 is tightened;

[0082] S5. The winding device starts to wind the non-woven fabric 300 that has completed dust removal in this section, thereby pulling the non-woven fabric 300 into the dust removal box 100, and repeating S3 - S5 to continuously remove dust from the non-woven fabric 300.

[0083] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the patent of the present invention.
