Description

Technical Field

[0001] The present application relates to the field of textile machinery, and in particular to a non-woven fabric splicing system. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, is a fabric-like material made by bonding short fibers (short) and long fibers (continuous long) together through chemical, mechanical, heat treatment or solvent treatment. They are flat or tufted porous sheets directly made from individual fibers, molten plastic or plastic films. Non-woven fabrics have special functions such as water absorption, liquid repellency, resilience, stretchability, softness, strength, flame retardancy, washability, cushioning, heat insulation, sound insulation, filtration, acting as a bacterial barrier and sterility. These properties are usually combined to create fabrics suitable for specific jobs while achieving a good balance between product service life and cost.

[0003] Non-woven fabrics can imitate the appearance, texture and strength of woven fabrics. When combined with other materials, they provide a range of products with different properties, which can be used alone or as components of clothing, household items, healthcare, engineering, industrial and consumer goods. Usually, when it is desired to splice multiple rolls of non-woven fabric, it is necessary to manually observe the remaining situation of the previous roll of non-woven fabric. When it is observed that the remaining amount of the previous roll of non-woven fabric reaches the situation where splicing is required, the device is stopped. Then, the end of the next roll of non-woven fabric transported is manually manipulated to coincide with the previous roll of non-woven fabric, and the manual operation of the fabric splicing mechanism is used to splice the two rolls of non-woven fabric. After splicing is completed, the excess non-woven fabric is cut off, and the device is started until non-woven fabric splicing is required again.

[0004] Regarding the above related technologies, the inventor believes that during the process of splicing non-woven fabric, it takes a long time, and the time consumption can even reach several minutes. Summary of the Invention

[0005] In order to save the fabric splicing time of non-woven fabric, the present application provides a non-woven fabric splicing system.

[0006] A non-woven fabric splicing system provided by the present application adopts the following technical solutions:

[0007] A non-woven fabric splicing system includes:

[0008] A rewinding device, including a rewinding bracket and a turntable arranged on the rewinding bracket through a rotating shaft. The turntable is provided with a first fixing portion for detachably fixing a first unwinding roller and a second fixing portion for detachably fixing a second unwinding roller at intervals. Among them, the first unwinding roller and the second unwinding roller are both rotatably arranged on the turntable and alternate in feeding the fabric;

[0009] The cloth receiving device is arranged on one side of the unwinding device and includes a clamping mechanism, a pressing mechanism, and a first flying knife mechanism;

[0010] The cloth guiding mechanism includes a first roller group and a second roller group arranged between the unwinding device and the cloth receiving device, and a third roller group arranged on the other side of the cloth receiving device;

[0011] The control mechanism controls the unwinding device, the cloth receiving device, and the cloth guiding mechanism;

[0012] Wherein, before receiving the cloth, the non-woven fabric of the first unwinding roller is laid on the first roller group and the third roller group for cloth running;

[0013] When receiving the cloth, the non-woven fabric of the first unwinding roller is driven by the turntable and laid on the second roller group and the third roller group. The non-woven fabric of the second unwinding roller is laid on the first roller group and clamped by the clamping mechanism. The non-woven fabric of the first unwinding roller stops running, and the pressing mechanism presses the non-woven fabrics of the first unwinding roller and the second unwinding roller;

[0014] After receiving the cloth, the first flying knife mechanism cuts off the non-woven fabric of the first unwinding roller, and the clamping mechanism releases the non-woven fabric, so that the non-woven fabric of the second unwinding roller is laid on the first roller group and the third roller group for cloth running.

[0015] By adopting the above technical solution, during use, the first unwinding roller runs the cloth first. When there is a certain length of non-woven fabric remaining on the first unwinding roller, the control mechanism will control the unwinding device to rotate the turntable, turn the second unwinding roller to the original position of the first unwinding roller, and pass the non-woven fabric of the second unwinding roller through the first roller group, the fourth roller group, and the third roller group. After the non-woven fabric is fixed by the clamping mechanism, the pressing mechanism will press and splice the non-woven fabrics of the two different rolls. After the splicing is completed, the first flying knife group will cut off the cloth of the first unwinding roller to complete the splicing of the cloth. After the splicing is completed, the second unwinding roller continues to release the cloth. When the remaining amount of cloth on the second unwinding roller reaches a certain length, the control mechanism controls the unwinding device to rotate the turntable, and rotates the first unwinding roller with a newly installed cloth roll manually to the position of the second unwinding roller just now, and repeats the operation. During the operation, only when the clamping mechanism fixes the end of the next roll of cloth to be spliced, it is necessary to stop the machine and fix it manually. After the fixing is completed, the subsequent operations are completed through the control device, so as to reduce the time consumption. In some cases, it takes only a dozen seconds or even a few seconds to complete the cloth receiving.

[0016] Preferably, the clamping mechanism includes a clamping table, a pressing table arranged on the clamping table and having a top surface forming a pressing surface, pressing plates respectively arranged on opposite sides of the pressing table, and a first driving member for driving each pressing plate, wherein the pressing plates reciprocate in directions away from and towards the side walls of the pressing table, and the pressing mechanism is pressed against the pressing surface.

[0017] By adopting the above technical solution, when splicing the non-woven fabrics, the non-woven fabric on the second unwinding roller is passed through the first guide roller group and the fourth guide roller group. After adjusting the position, the first driving member is started to fix the non-woven fabric with the pressing plates. At this time, the non-woven fabric on the second unwinding roller on the pressing table coincides with the remaining non-woven fabric left on the first unwinding roller, and the splicing of the non-woven fabrics can be completed on the pressing table through the pressing mechanism.

[0018] Preferably, the clamping mechanism further includes a second flying knife mechanism arranged on the clamping table. The second flying knife mechanism is located on one side of the pressing table close to the third guide roller group, and relative to the pressing plates, the second flying knife mechanism is close to the top surface of the pressing table.

[0019] By adopting the above technical solution, after the non-woven fabrics on the first unwinding roller and the second unwinding roller are pressed and spliced, the first flying knife mechanism cuts the non-woven fabric on the first unwinding roller, and the second flying knife mechanism cuts the redundant non-woven fabric of the second unwinding roller used for fixing, ensuring that the joint is neat and there is no redundant fabric head after the two rolls of non-woven fabrics are pressed and spliced.

[0020] Preferably, the clamping mechanism further includes a fourth guide roller group arranged on the clamping table, a support plate reciprocating perpendicular to the clamping table, and a second driving member for driving the support plate. The support plate and the fourth guide roller group support the non-woven fabric, and in the direction from the first guide roller group to the third guide roller group, they are the fourth guide roller group, the support plate, and the pressing plates in sequence.

[0021] By adopting the above technical solution, the fourth guide roller group plays an auxiliary role in splicing and conveying the non-woven fabric. And when splicing the non-woven fabric, the non-woven fabric needs to be straightened to avoid wrinkles affecting the splicing. At this time, both the support plate and the fourth guide roller group can support the non-woven fabric.

[0022] Preferably, it further includes an inclined sliding table, with the end of the sliding table close to the unwinding device being lower than the end far from the unwinding device. The clamping mechanism is reciprocatingly arranged on the sliding table in directions towards and away from the unwinding device, and the pressing mechanism is located above the sliding table.

[0023] By adopting the above technical solution, the sliding table is inclined, which can ensure to the greatest extent that the fabrics on the first unwinding roller and the second unwinding roller do not interfere with each other during the fabric connection and transmission processes, making the operation smoother. When fabric connection is required, the clamping mechanism slides towards the unwinding device. After manually fixing the non-woven fabric on the second unwinding roller to the clamping mechanism, the clamping mechanism moves the non-woven fabric on the second unwinding roller away from the unwinding device until the pressing mechanism can work normally for fabric connection. When the non-woven fabric on the second unwinding roller is almost used up, the clamping mechanism slides towards the unwinding device again to repeat the operation.

[0024] Preferably, the pressing mechanism includes a fixed table, a welding head arranged on the fixed table, and a fifth guide roller arranged on the fixed table. Among them, during fabric connection, the non-woven fabric of the first unwinding roller is successively laid on the second guide roller group, the fifth guide roller, and the third guide roller group.

[0025] By adopting the above technical solution, during the initial fabric connection, the fifth guide roller mainly plays a role in guiding and supporting the non-woven fabric on the first unwinding roller. However, when the fabric connection is completed and the non-woven fabric on the second unwinding roller also reaches the remaining amount of the non-woven fabric on the initial first unwinding roller, the second unwinding roller rotates through the turntable to reach the fabric connection position of the initial first unwinding roller. At this time, the fifth guide roller plays a supporting role for the non-woven fabric on the second unwinding roller. Therefore, the fifth guide roller mainly plays a supporting role for the fabric on the unwinding roller far from the unwinding bracket.

[0026] Preferably, the pressing mechanism is an ultrasonic pressing mechanism or a hot pressing mechanism.

[0027] By adopting the above technical solution, since the non-woven fabric needs to be heated for splicing, the pressing mechanism can use ultrasonic or ordinary hot pressing to splice the non-woven fabric.

[0028] Preferably, the axes of the first unwinding roller, the rotating shaft, and the second unwinding roller are coplanar, and the second guide roller group is arranged on the turntable.

[0029] By adopting the above technical solution, if the axes of the first unwinding roller and the second unwinding roller are coplanar, during fabric connection, the turntable is rotated to the position where the connection line between the first unwinding roller and the second unwinding roller is perpendicular to the connection line between the original first unwinding roller and the second unwinding roller. At this time, during fabric connection, it can be ensured to the greatest extent that the non-woven fabrics on the first unwinding roller and the second unwinding roller do not interfere with each other during operation. The main function of the second guide roller group is to support the non-woven fabric on the unwinding roller far from the unwinding bracket, and it is also to ensure that the non-woven fabrics on the first unwinding roller and the second unwinding roller do not interfere with each other during splicing, avoiding affecting the operation.

[0030] Preferably, it further includes a cloth storage device located downstream of the cloth receiving device. When receiving the cloth, the third roller group presses the non-woven fabric on the first unwinding roller, and the cloth storage device feeds the cloth; after the cloth receiving is completed, the third roller group releases the non-woven fabric on the first unwinding roller, and the cloth storage device stores the cloth when feeding the cloth.

[0031] By adopting the above technical solution, when the third roller group presses the non-woven fabric on the first unwinding roller, all the non-woven fabrics on the side of the third roller group close to the unwinding device do not participate in cloth storage, which is convenient for manual operation to prepare for subsequent cloth receiving. After the cloth receiving is completed, releasing the third roller group allows the spliced non-woven fabric to continue feeding and complete cloth storage.

[0032] Preferably, the cloth storage device includes a cloth storage bracket, a plurality of first cloth storage rollers arranged at the top of the cloth storage bracket, and a plurality of second cloth storage rollers movably arranged along the direction from the top to the bottom of the cloth storage bracket at the bottom of the cloth storage bracket. The plurality of first cloth storage rollers and the plurality of second cloth storage rollers are arranged in sequence along the cloth feeding direction, and the non-woven fabric alternately passes through the first cloth storage rollers and the second cloth storage rollers, and the plurality of second cloth storage rollers are movably arranged along the direction from the top to the bottom of the cloth storage bracket.

[0033] By adopting the above technical solution, after the third roller group clamps the non-woven fabric, to ensure the smooth progress of cloth storage, the second cloth storage roller will move towards the first cloth storage roller according to the cloth storage situation. After the third roller group releases the non-woven fabric and continues to feed the cloth, the second cloth storage roller will move away from the first cloth storage roller, ensuring that cloth storage is not affected when the side of the third roller group close to the unwinding device does not feed the cloth, and improving work efficiency.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. During use, the first unwinding roller feeds the fabric first. When there is a certain length of non-woven fabric remaining on the first unwinding roller, the control mechanism will control the unwinding device to rotate the turntable, turning the second unwinding roller to the original position of the first unwinding roller. The non-woven fabric of the second unwinding roller will pass through the first guide roller group, the fourth guide roller group, and the third guide roller group. After the non-woven fabric is fixed by the clamping mechanism, the pressing mechanism will press and splice the two different rolls of non-woven fabric. After the splicing is completed, the first flying knife group will cut the fabric on the first unwinding roller to complete the splicing of the fabric. After the splicing is completed, the second unwinding roller continues to feed the fabric. When the remaining fabric length on the second unwinding roller reaches a certain length, the control mechanism controls the unwinding device to rotate the turntable, turning the first unwinding roller with a newly installed fabric roll to the position of the second unwinding roller just now and repeating the operation. During the operation, it is only necessary to stop the machine and fix it manually when the clamping mechanism fixes the end of the next fabric roll to be spliced. After the fixing is completed, the subsequent operation is completed through the control device, achieving the purpose of reducing the time consumption. In some cases, it takes only a dozen seconds or even a few seconds to complete the fabric connection.

[0036] 2. The sliding table is inclined to ensure that the fabrics on the first unwinding roller and the second unwinding roller do not interfere with each other during the fabric connection and transmission processes to make the operation smoother. When fabric connection is required, the clamping mechanism slides towards the unwinding device. After manually fixing the non-woven fabric on the second unwinding roller to the clamping mechanism, the clamping mechanism moves the non-woven fabric on the second unwinding roller away from the unwinding device until the pressing mechanism can work normally for fabric connection. When the non-woven fabric on the second unwinding roller is almost used up, the clamping mechanism slides towards the unwinding device again and repeats the operation.

[0037] 3. After the third guide roller group clamps the non-woven fabric, to ensure the smooth storage of the fabric, the second storage roller will move towards the first storage roller according to the storage situation of the fabric. After the third guide roller group releases the non-woven fabric and continues to feed the fabric, the second storage roller will move away from the first storage roller to ensure that the fabric does not affect the storage even when the third guide roller group is close to the unwinding device and no fabric is fed, improving the work efficiency.

[0043] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0044] An embodiment of the present application discloses a non-woven fabric cloth joining system. Referring to Figure 1 and Figure 2 , the non-woven fabric cloth joining machine includes an unwinding device 1, a cloth receiving device 2 arranged on one side of the unwinding device 1, and a cloth storage device 3 arranged on the side of the cloth receiving device 2 away from the unwinding device 1. A first guide roller group 41 is arranged between the unwinding device 1 and the cloth receiving device 2, and a third guide roller group 43 is arranged at one end of the cloth receiving device 2 away from the unwinding device 1. The unwinding device 1 includes an unwinding support 11 and a turntable 12 arranged on the unwinding support 11. The unwinding support 11 is two relatively arranged trapezoidal seats, and extension blocks are arranged on the end faces of the trapezoidal seats away from the ground. A rotating shaft 14 is arranged between the two trapezoidal seats. Both ends of the rotating shaft 14 are arranged at the junctions of the trapezoidal blocks and the extension blocks, and both ends of the rotating shaft 14 are vertically connected to the two trapezoidal seats and the extension blocks respectively. There are two turntables 12, and both turntables 12 are rotatably arranged on the rotating shaft 14, and the two turntables 12 are respectively arranged close to the two trapezoidal seats.

[0045] Referring to Figure 1 and Figure 2, a first fixing part for detachably fixing the first unwinding roller 15 and a second fixing part for detachably fixing the second unwinding roller 16 are arranged at intervals between the two turntables 12. Among them, both the first unwinding roller 15 and the second unwinding roller 16 are rotatably arranged on the turntable 12 and feed the cloth alternately, and the axes of the first unwinding roller 15, the second unwinding roller 16 and the rotating shaft 14 are coplanar. A second guide roller group 42 is arranged on the turntable 12. The second guide roller group 42 includes a plurality of second guide rollers. In this embodiment, four second guide rollers are taken as an example for illustration. The four second guide rollers are in pairs corresponding to each other, and the two corresponding second guide rollers are both centrosymmetrically arranged with the rotating shaft 14 as the center. The four second guide rollers need to meet the requirement that the first unwinding roller 15 and the second unwinding roller 16 play a supporting role for the non-woven fabric during unwinding, and ensure that the first unwinding roller 15 and the second unwinding roller 16 do not interfere with each other during the unwinding process.

[0046] Refer to Figure 1 and Figure 3 , the cloth receiving device 2 includes a sliding table 21, a clamping mechanism 22 arranged on the sliding table 21 for clamping the non-woven fabric, a pressing mechanism 23 for connecting the non-woven fabric, and a first flying knife mechanism 24 for cutting the non-woven fabric after the cloth receiving is completed. An electric guide rail is arranged on any one side of the sliding table 21. The side of the sliding table 21 provided with the electric guide rail is the working surface, and the working surface of the sliding table 21 is arranged in a direction away from the ground. The sliding table 21 is inclined, and the end of the sliding table 21 close to the unwinding device 1 is lower than the end far from the unwinding device 1. The clamping mechanism 22 is reciprocally movable on the sliding table 21 in a direction close to and away from the unwinding device 1, and the pressing mechanism 23 is located above the sliding table 21.

[0047] Refer to Figure 3 , the clamping mechanism 22 includes a clamping table 221. The clamping table 221 is slidably arranged on the electric guide rail. A support plate 222 is vertically arranged on the clamping table 221. The support plate 222 reciprocates along the electric guide rail. Among them, the power source of the support plate 222 is a second driving member 223, and the second driving member 223 is the motor of the electric guide rail. A pressing table 224 is also vertically arranged on the clamping table 221. The top surface of the pressing table 224 constitutes a pressing surface. Pressing plates 225 are respectively arranged on the two opposite sides of the pressing table 224. Each pressing plate 225 is driven by a first driving member 226. Among them, the pressing plates 225 reciprocally move in a direction away from and close to the side wall of the pressing table 224. The pressing mechanism 23 is pressed against the pressing surface. The clamping mechanism 22 further includes a fourth guide roller group 25 arranged on the clamping table 221. The support plate 222 and the fourth guide roller group 25 support the non-woven fabric, and in the direction from the first guide roller group 41 to the third guide roller group 43, they are successively the fourth guide roller group 25, the support plate 222 and the pressing plates 225.

[0048] Refer to Figure 3, the clamping mechanism 22 further includes a second flying knife mechanism 227. The second flying knife mechanism 227 is arranged on the clamping table 221, and the second flying knife mechanism 227 is located on the side of the pressing table 224 close to the third roller group 43. The second flying knife mechanism 227 is closer to the top surface of the pressing table 224 than the pressing plate 225. During the process of connecting non-woven fabrics, the non-woven fabric head of the first unwinding roller 15 or the second unwinding roller 16 close to the unwinding bracket 11 is first fixed to the side surface of the pressing plate 225 away from the unwinding device 1 by the first driving member 226, and then the non-woven fabric is arranged obliquely. The inclined non-woven fabric is close to the connection between the pressing plate 225 and the clamping table 221, and the inclined non-woven fabric is fixed to the side surface of the pressing plate 225 close to the unwinding device 1 by the first driving member 226.

[0049] Referring to Figure 3 , the pressing mechanism 23 includes a fixed table 231. The fixed table 231 is arranged above the clamping mechanism 22. A welding head 232 and a fifth roller 233 are arranged on the fixed table 231. Among them, during cloth connection, the non-woven fabric of the first unwinding roller 15 or the second unwinding roller 16 far from the unwinding bracket 11 is sequentially laid on the second roller group 42, the fifth roller 233, and the third roller group 43. According to the thermoplasticity of the non-woven fabric itself, that is, it will soften and melt when heated to a certain temperature and become a viscous fluid with a certain fluidity, and will solidify again when the temperature is lower than its softening and melting temperature and become solid. Therefore, the pressing mechanism 23 can adopt ultrasonic pressing or hot pressing. In this embodiment, hot pressing is taken as an example for illustration. The use of the hot pressing mechanism 23 can make full use of the thermoplasticity of the non-woven fabric, so that some fibers in the fiber web soften and melt when heated, adhesions are generated between the fibers, and the fibers remain adhered after cooling, and the fiber web is strengthened, so as to splice two different non-woven fabrics.

[0050] Referring to Figure 3 , the welding head 232 is driven by a third driving member 234. The welding head 232 reciprocates in the directions close to and away from the pressing surface. And when the welding head 232 moves in the direction close to the pressing surface, until the welding head 232 abuts against the pressing surface and stays for a period of time to completely press the two non-woven fabrics together. Among them, the third driving member 234 is a plurality of cylinders, and the welding head 232 is a heating plate fixedly connected to the end of the cylinder piston rod. After pressing is completed, the second flying knife mechanism 227 will cut the non-woven fabric of the first unwinding roller 15 or the second unwinding roller 16 close to the unwinding bracket 11, and cut off the non-woven fabric that is redundant relative to the joint for fixation, so as to ensure the flatness of the non-woven fabric after cloth connection.

[0051] Referring to Figure 1 , the cloth storage device 3 is located downstream of the cloth connection device 2. Referring to Figure 4, the cloth storage device 3 includes a cloth storage support 31, a plurality of first cloth storage guide rollers 32 arranged at the top end of the cloth storage support 31, and a plurality of second cloth storage guide rollers 33 movably arranged along the direction from the top end to the bottom end of the cloth storage support 31 at the bottom end of the cloth storage support 31. The plurality of first cloth storage guide rollers 32 and the plurality of second cloth storage guide rollers 33 are arranged in sequence along the cloth feeding direction. The non-woven fabric alternately passes through the first cloth storage guide rollers 32 and the second cloth storage guide rollers 33 in turn, and the plurality of second cloth storage guide rollers 33 are movably arranged along the direction from the top end to the bottom end of the cloth storage support 31. Refer to Figure 1 , wherein, during cloth receiving, the third guide roller group 43 presses the non-woven fabric of the first unwinding roller 15 or the second unwinding roller 16 away from the unwinding support 11, and the cloth storage device 3 feeds the cloth; after the cloth receiving is completed, the third guide roller group 43 releases the non-woven fabric of the first unwinding roller 15 or the second unwinding roller 16 away from the unwinding support 11, and the cloth storage device 3 stores the cloth while feeding the cloth.

[0052] Refer to Figure 1 , during the process of cloth receiving and cloth storage, the first guide roller group 41 and the second guide roller group 42 arranged between the unwinding device 1 and the cloth receiving device 2, and the third guide roller group 43 arranged on the other side of the cloth receiving device 2 are the cloth guiding mechanism 4; the control mechanism controls the unwinding device 1, the cloth receiving device 2 and the cloth guiding mechanism 4. Induction devices are arranged on both the first unwinding roller 15 and the second unwinding roller 16. When the induction devices sense that the remaining amount of the non-woven fabric on the first unwinding roller 15 and the second unwinding roller 16 is the same as the value of the pre-set remaining amount of the non-woven fabric, the control mechanism will control the turntable 12 to rotate, the clamping mechanism 22 moves towards the direction of the unwinding device 1, the third unwinding roller clamps the non-woven fabric. After manually fixing the new roll of non-woven fabric to be joined, the clamping mechanism 22 moves towards the direction away from the unwinding device 1, the control pressing mechanism 23 performs pressing, the second cloth storage guide roller 33 moves towards the first cloth storage guide roller 32, and after the pressing is completed, the second cloth storage guide roller 33 moves towards the direction away from the first cloth storage guide roller 32, and the turntable 12 rotates again.

[0053] The implementation principle of the embodiment of this application is as follows: During use, the first unwinding roller 15 feeds the fabric first. When there is a certain remaining length of the non-woven fabric on the first unwinding roller 15, the control mechanism controls the unwinding device 1 to rotate the turntable 12, and passes the non-woven fabric of the second unwinding roller 16 through the first guide roller group 41, the fourth guide roller group 25, and the third guide roller group 43. After the non-woven fabric is fixed by the clamping mechanism 22, the pressing mechanism 23 presses and joins the two different rolls of non-woven fabric. After the joining is completed, the first flying knife group cuts the fabric on the first unwinding roller 15, and the second flying knife group cuts the fabric on the second unwinding roller 16 to complete the fabric joining. After the joining is completed, the second unwinding roller 16 is rotated to the original position of the first unwinding roller 15, and the second unwinding roller 16 continues to feed the fabric. When the remaining amount of the fabric on the second unwinding roller 16 reaches the set length, the control mechanism controls the unwinding device to rotate the turntable 12 and repeats the operation. During the operation, it is only necessary to stop the machine and fix it manually when the clamping mechanism 22 fixes the end of the next roll of fabric to be joined. After the fixing is completed, the subsequent operation is completed through the control device.

[0054] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
