Description

Technical Field

[0001] This invention relates to the field of opening technology for spunlace nonwoven fabric raw materials, specifically to an opening device for spunlace nonwoven fabric raw materials. Background Technology

[0002] Spunlace nonwoven fabric is made by spraying high-pressure micro-jet water onto one or more layers of fiber web, causing the fibers to entangle and form a fabric with a certain strength. The fiber raw materials for this type of nonwoven fabric are widely available, including polyester, nylon, polypropylene, viscose fiber, chitosan fiber, microfiber, Tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc.

[0003] Currently, the opening of spunlace nonwoven fabric is simply done by using a rotating roller with comb needles on its surface to stretch and cut the spunlace nonwoven fabric at high speed. However, since the raw materials of spunlace nonwoven fabric may have clumps of dirt on the fabric during accumulation, traditional fabric opening machines cannot effectively open the fabric, resulting in the fabric still having clumps. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a spunlace nonwoven fabric raw material opening device, which solves the problem that the presence of soil clumps on the fabric results in poor fabric opening performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A spunlace nonwoven fabric raw material opening device includes a support frame, a feeding trough on the support frame, a conveyor belt installed on the support frame, a processing cylinder fixedly installed on the support frame, a feeding port on the processing cylinder, two sets of support columns rotatably installed on the support frame, and a motor fixedly installed on the support frame. The support frame is equipped with a dispersing mechanism that improves the opening effect of the spunlace nonwoven fabric. The support frame is equipped with a separation mechanism that separates the spunlace nonwoven fabric from the dust on its surface. The support frame is equipped with a cleaning mechanism for cleaning the processing cylinder. By starting the motor, the dispersing mechanism rotates and drives the separation mechanism to move. The separation mechanism drives the cleaning mechanism to move, causing the separation mechanism to strike the surface of the processing cylinder.

[0006] Preferably, the dispersing mechanism includes a drive gear rotatably mounted on a support frame and fixedly connected to the output end of a motor. Two sets of rotating columns fixedly connected to support columns are rotatably mounted on the support frame. Each set of rotating columns is fixedly mounted with a connecting gear meshing with the drive gear. Multiple sets of rubber rods are fixedly mounted on each set of support columns. Multiple sets of rubber granules are fixedly mounted on each set of rubber rods.

[0007] Preferably, the separation mechanism includes an arc-shaped plate fixedly mounted on a rotating column, an incomplete gear fixedly mounted on the arc-shaped plate, and a limit plate slidably mounted on the support frame.

[0008] Preferably, the separation mechanism further includes two sets of toothed plates fixedly mounted on the limiting plate and meshing with the incomplete gear. The toothed plates are provided with inclined grooves. A fixing plate is fixedly mounted on the limiting plate. Multiple sets of semi-circular rubbing plates that cooperate with the rubber rod are fixedly mounted on the fixing plate. A support rod that is slidably connected to the fixing plate is fixedly mounted on the processing cylinder.

[0009] Preferably, the cleaning mechanism includes a connecting block fixedly installed on the limiting plate, and the support frame is provided with two sets of limiting grooves. Two sets of fixing rods are fixedly installed on each set of limiting grooves, and a limiting block that is slidably connected to the fixing rods is slidably installed on each set of limiting grooves.

[0010] Preferably, the cleaning mechanism further includes two sets of connecting plates rotatably mounted on the connecting block and rotatably connected to the limiting block. A fixing block is fixedly mounted on the limiting block, a first gear is rotatably mounted on the fixing block, and two sets of fixing shafts are fixedly mounted on the first gear.

[0011] Preferably, the cleaning mechanism further includes a torsion spring sleeved on a fixed shaft, wherein a set of protrusions are fixedly installed on a set of the fixed shafts, and two sets of semicircular blocks that cooperate with the protrusions are fixedly installed on the support frame, and a connecting shaft is rotatably installed on the fixed blocks.

[0012] Preferably, the cleaning mechanism further includes a second gear fixedly mounted on the connecting shaft and meshing with the first gear, a rotating rod fixedly mounted on the connecting shaft, and a striking block fixedly mounted on the rotating rod.

[0013] Preferably, an opening roller and a feeding pressure roller are rotatably mounted on the support frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a dispersing mechanism, through which a motor drives a gear to rotate, which in turn drives a rubber rod on a support column to rotate, thereby performing secondary opening of the spunlace nonwoven fabric raw material in the processing cylinder, breaking up any clumps of the raw material, and avoiding the situation where the fabric has clumps of dirt, resulting in poor opening effect.

[0015] 2. The present invention, through the setting of the separation mechanism, causes the limiting plate to move by rotating the rotating column, which in turn moves the fixing plate and the semi-circular rubbing plate. The rotating rubber rod deforms after contacting the semi-circular rubbing plate, which can remove the clumps that are difficult to clean from the raw material, thus avoiding the situation where the clumps of dirt remain on the fabric for a long time and are difficult to separate from the fabric.

[0016] 3. The present invention, through the setting of the cleaning mechanism, when the connecting block is driven away from the limiting block by the limiting plate, the semi-circular block contacts the protrusion, causing the torsion spring to deform under force. When the movement of the protrusion causes it to no longer contact the semi-circular block, the striking block is reset under the action of the torsion spring and strikes the surface of the processing cylinder, causing the raw material on the inner wall of the processing cylinder to fall off.

[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Example 1 The presence of clumps of dirt on the fabric resulted in poor fabric opening. To address this issue, refer to... Figures 1-6 This embodiment proposes a spunlace nonwoven fabric raw material opening device, including a support frame 1, a feeding trough 11 on the support frame 1, a conveyor belt 12 installed on the support frame 1, a processing cylinder 13 fixedly installed on the support frame 1, a feeding port 14 on the processing cylinder 13, two sets of support columns 15 rotatably installed on the support frame 1, a motor 16 fixedly installed on the support frame 1, an opening roller 5 rotatably installed on the support frame 1, a feeding pressure roller 501 rotatably installed on the support frame 1, and a drive device for driving the opening roller 5 and the feeding pressure roller 501 to rotate is installed inside the support frame 1. The spunlace nonwoven fabric is fed into the device through the feeding trough 11 and moved by the feeding pressure roller 501. The spunlace nonwoven fabric is opened once by the high-speed rotating opening roller 5. After opening, the spunlace nonwoven fabric is transported by the conveyor belt 12 and enters the processing cylinder 13 through the feeding port 14.

[0021] The support frame 1 is equipped with a dispersing mechanism 2 to improve the opening effect of the spunlace nonwoven fabric. The support frame 1 is also equipped with a separation mechanism 3 to separate the spunlace nonwoven fabric from the dust on its surface. The support frame 1 is further equipped with a cleaning mechanism 4 to clean the treatment cylinder 13. By starting the motor 16, the dispersing mechanism 2 rotates and drives the separation mechanism 3 to move. The separation mechanism 3 drives the cleaning mechanism 4 to move, causing the separation mechanism 3 to strike the surface of the treatment cylinder 13, causing the spunlace nonwoven fabric to fall off the inner wall of the treatment cylinder 13.

[0022] The dispersing mechanism 2 includes a drive gear 201 rotatably mounted on a support frame 1 and fixedly connected to the output end of a motor 16. Two sets of rotating columns 202 fixedly connected to support columns 15 are rotatably mounted on the support frame 1. Each set of rotating columns 202 is fixedly mounted with a connecting gear 203 that meshes with the drive gear 201. Each set of support columns 15 is fixedly mounted with multiple sets of rubber rods 204. Each set of rubber rods 204 is fixedly mounted with multiple sets of rubber granules 205. The rubber rods 204 have a certain degree of flexibility, which can prevent a lot of debris from being generated during the process of loosening the spunlace nonwoven fabric. The motor 16 causes the drive gear 201 to rotate, which drives the rotating columns 202 connected to the connecting gears 203 to rotate. The rotation of the rotating columns 202 drives the rubber rods 204 on the support columns 15 to rotate, thereby performing secondary loosening of the spunlace nonwoven fabric raw material in the processing cylinder 13, breaking up the clumps of raw material, and avoiding the situation where there are clumps of dirt on the fabric, resulting in poor fabric loosening effect. Example 2 Because the clumps of soil remain on the fabric for a long time, making them difficult to separate, this problem can be solved by referring to... Figures 1-6The separation mechanism 3 includes an arc-shaped plate 301 fixedly mounted on a rotating column 202. An incomplete gear 302 is fixedly mounted on the arc-shaped plate 301. A limit plate 303 is slidably mounted on the support frame 1. The separation mechanism 3 also includes two sets of toothed plates 304 fixedly mounted on the limit plates 303 and meshing with the incomplete gear 302. The toothed plates 304 have inclined grooves 305. When the arc-shaped plate 301 rotates, it contacts the inclined grooves 305 and drives the limit plate 303 to move, so that the toothed plates 304 mesh with the incomplete gear 302. A fixed plate 306 is fixedly mounted on the limit plate 303. Multiple sets of semi-circular rubbing plates 307 that cooperate with the rubber rod 204 are fixedly mounted on the fixed plate 306. A support rod 308 that is slidably connected to the fixed plate 306 is fixedly mounted on the processing cylinder 13, so that the movement of the fixed plate 306 is more stable. The rotation of the rotating column 202 drives the arc-shaped plate 301 to move. 01 rotates, the arc plate 301 rotates and drives the incomplete gear 302 to rotate. When one set of arc plates 301 rotates and contacts the inclined groove 305, the toothed plate 304 meshes with the incomplete gear 302 above it, which can drive the limiting plate 303 to move. When the incomplete gear 302 and the toothed plate 304 are not meshing, the other set of arc plates 301 rotates and contacts the inclined groove 305, which causes the toothed plate 304 to mesh with the incomplete gear 302 above it, thereby continuing to drive the limiting plate 303 to move in the opposite direction, so that the limiting plate 303 reciprocates within the support frame 1. The movement of the limiting plate 303 drives the fixed plate 306 and the semi-circular rubbing plate 307 to move. When the rotating rubber rod 204 contacts the semi-circular rubbing plate 307, it will deform, which can remove the clumps that are difficult to clean from the raw material, avoiding the situation where the clumps of dirt remain on the fabric for a long time and are difficult to separate from the fabric.

[0023] Example 3 Since loosened fabric adhering to the inner wall of the processing drum can affect subsequent fabric loosening, this problem is addressed by referring to... Figures 1-6The cleaning mechanism 4 includes a connecting block 401 fixedly installed on the limiting plate 303. The support frame 1 has two sets of limiting grooves 402, each with two sets of fixing rods 403 fixedly installed to ensure more stable movement of the limiting block 404. Each limiting groove 402 also has a limiting block 404 slidably installed and slidably connected to the fixing rods 403. The cleaning mechanism 4 also includes two sets of connecting plates 405 rotatably installed on the connecting block 401 and rotatably connected to the limiting block 404. A fixing block is fixedly installed on the limiting block 404. 406. A first gear 407 is rotatably mounted on the fixed block 406. Two sets of fixed shafts 408 are fixedly mounted on the first gear 407. The cleaning mechanism 4 also includes a torsion spring 409 sleeved on the fixed shaft 408, so that the fixed shaft 408 can drive the first gear 407 to quickly reset. A protrusion 410 is fixedly mounted on one set of fixed shafts 408. Two sets of semi-circular blocks 411 that cooperate with the protrusion 410 are fixedly mounted on the support frame 1. A connecting shaft 412 is rotatably mounted on the fixed block 406. The cleaning mechanism 4 also includes a fixed mounting A second gear 413 is mounted on the connecting shaft 412 and meshes with the first gear 407. A rotating rod 414 is fixedly mounted on the connecting shaft 412, and a striking block 415 is fixedly mounted on the rotating rod 414. When the limiting plate 303 drives the connecting block 401 away from the limiting block 404, the two sets of limiting blocks 404 move and the distance between them decreases under the action of the connecting plate 405. When the semicircular block 411 contacts the protrusion 410, it blocks the protrusion 410, causing the protrusion 410 to drive the first gear 407 connected to the fixed shaft 408 to rotate. When the torsion spring 409 is deformed by the force, the first gear 407 rotates, driving the connecting shaft 412 connected to the second gear 413 to rotate. The rotation of the connecting shaft 412 drives the striking block 415 on the rotating rod 414 to rotate. As the protrusion 410 moves and is no longer in contact with the semi-circular block 411, the striking block 415 is reset under the action of the torsion spring 409 and strikes the surface of the processing cylinder 13, causing the raw material on the inner wall of the processing cylinder 13 to fall off. This avoids the situation where the loosened fabric sticks to the inner wall of the processing cylinder 13 and affects the subsequent loosening of the fabric.

[0024] Working principle: The spunlace nonwoven fabric is fed into the device through the feeding trough 11, and the feeding pressure roller 501 drives the spunlace nonwoven fabric to move. The high-speed rotating opening roller 5 performs a first opening treatment on the spunlace nonwoven fabric. After opening, the spunlace nonwoven fabric is transported by the conveyor belt 12 and enters the processing cylinder 13 through the feed port 14. The motor 16 drives the drive gear 201 to rotate, which drives the rotating column 202 connected to the connecting gear 203 to rotate. The rotation of the rotating column 202 drives the rubber rod 204 on the support column 15 to rotate. The hydroentangled nonwoven fabric raw material in the processing cylinder 13 undergoes secondary loosening to break up any clumps. The rotating column 202 rotates, causing the arc-shaped plate 301 to rotate. The arc-shaped plate 301 then rotates, causing the incomplete gear 302 to rotate. When one set of arc-shaped plates 301 rotates and contacts the inclined groove 305, the toothed plate 304 meshes with the incomplete gear 302 above it, which can move the limiting plate 303. When the incomplete gear 302 and the toothed plate 304 are no longer meshing, the other set of arc-shaped plates 301 rotates and contacts the inclined groove 305, causing the toothed plate 304 to mesh with the incomplete gear 302 above it. The gear 302 meshes, thus continuing to drive the limiting plate 303 to move in the opposite direction, causing the limiting plate 303 to reciprocate within the support frame 1. The movement of the limiting plate 303 drives the fixed plate 306 and the semi-circular rubbing plate 307 to move. The rotating rubber rod 204 deforms after contacting the semi-circular rubbing plate 307, which can remove clumps that are difficult to clean from the raw materials. When the limiting plate 303 drives the connecting block 401 away from the limiting block 404, the connecting plate 405 causes the two sets of limiting blocks 404 to move and the distance between them to decrease. When the semi-circular block 411 and the protrusion 41 When there is no contact, the protrusion 410 is blocked, causing the protrusion 410 to drive the first gear 407 connected to the fixed shaft 408 to rotate. The torsion spring 409 is deformed by force. The rotation of the first gear 407 drives the connecting shaft 412 connected to the second gear 413 to rotate. The rotation of the connecting shaft 412 drives the striking block 415 on the rotating rod 414 to rotate. As the protrusion 410 moves and is no longer in contact with the semicircular block 411, the striking block 415 is reset under the action of the torsion spring 409 and strikes the surface of the processing cylinder 13, causing the raw material on the inner wall of the processing cylinder 13 to fall off.
