Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric processing, and particularly relates to a nonwoven fabric processing system and processing method. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched nonwoven fabric, etc., is made of polyester fiber and is produced through needle-punching process. Due to its many advantages such as moisture resistance, breathability, flexibility, lightness, thinness, flame retardancy, non-toxicity and odorlessness, it is widely used in various industries. In the process of producing nonwoven fabric, it is necessary to roll up the formed nonwoven fabric onto multiple rolls to facilitate subsequent storage and transportation operations. However, in the existing technology, when the number of nonwoven fabric layers rolled on a roll reaches the target requirement, the roll needs to be manually replaced before the next winding operation. The manual replacement of rolls is time-consuming, labor-intensive and wastes human resources. Therefore, there is a need for a device that can automatically replace the nonwoven fabric rolls after winding. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a device that facilitates the automatic replacement of nonwoven fabric rolls after winding.

[0004] A nonwoven fabric processing system includes a base frame and a connecting plate. A slide bar is slidably connected to the base frame, a drive roller is rotatably connected to the slide bar, and a driven roller is rotatably connected to the base frame. The drive roller has a protrusion, and the driven roller has a groove into which the protrusion can slide. A clamping head is slidably connected to the driven roller. The connecting plate has multiple threaded holes, a replacement seat is slidably connected to the connecting plate, a clamping arc plate is slidably connected to the replacement seat, and an arc panel is fixedly attached to the replacement seat.

[0005] It also includes a cutter that is slidably connected to the base frame. A cutting seat I is fixedly connected to the base frame, and a cutting seat II is connected to the cutting seat I. Both the cutting seat I and the cutting seat II are provided with a cutting groove.

[0006] It also includes a pressure roller that is slidably connected to the cutter, a spring I that is fixed between the pressure roller and the cutter, and multiple springs II that are fixed between the clamping head and the base frame. The spring I is equipped with an electromagnetic block that can attract the pressure roller.

[0007] The nonwoven fabric processing system described above is used to process nonwoven fabrics, and the method includes the following steps:

[0008] S1. The drive roller rotates on the slide bar, and the protrusion on the drive roller cooperates with the slot on the driven roller to drive the driven roller to rotate, so that the drum on the drive roller rotates continuously with the drive roller under the clamping head and the drive roller.

[0009] S2. When one of the rolls on the drive roller reaches the target thickness, operate the cutter to slide downwards so that the cutter is inserted into the cutting grooves on the cutting seat I and the cutting seat II.

[0010] S3. Reset the cutter and activate the electromagnetic block on the cutter. Then slide the cutter again to make the pressure roller press the clamping head, so that the clamping head overcomes the elastic force of multiple springs II and slides on the driven roller.

[0011] S4. Slide the operating slider to move the drive roller to a position concentric with the arc panel on the replacement seat;

[0012] S5. Operate the change seat to slide until the change seat moves to the position where it coincides with the drum on the drive roller. Then slide the clamping arc plate downward so that the clamping arc plate and the change seat clamp the drum.

[0013] S6. Operate the replacement seat again to slide the drum off the drive roller, and move the robotic arm with the connecting plate to place the removed drum.

[0014] S7. Move the robotic arm that connects the connecting plate and slide it in coordination with the clamping arc plate, so that a brand new roll to be used is put back on the drive roller, and adhesive is dripped onto the roll through two dripping grooves;

[0015] S8. Reset the slide bar and slide the clamping head back. Then rotate the drive roller so that the side with the adhesive applied faces the rotating rod. Then rotate the rotating rod so that the rotating rod adheres the nonwoven fabric to the position on the drive roller where the adhesive was applied, thereby connecting the nonwoven fabric to the drive roller for subsequent winding.

[0027] See Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 The diagram illustrates an embodiment of the invention that facilitates automatic replacement of the wound-up nonwoven fabric roll. Further,

[0028] This system includes a base frame 101 and a connecting plate 701. A slide bar 201 is slidably connected to the base frame 101, and a drive roller 202 is rotatably connected to the slide bar 201. A driven roller 301 is rotatably connected to the base frame 101. The drive roller 202 has a protrusion, and the driven roller 301 has a groove, into which the protrusion can slide. A clamping head 302 is slidably connected to the driven roller 301. The connecting plate 701 has multiple threaded holes, and a replacement seat 702 is slidably connected to the connecting plate 701. A clamping arc plate is slidably connected to the replacement seat 702. 704. A first motor is fixedly connected to the base frame 101. A first lead screw is fixedly connected to the output shaft of the first motor. The first lead screw is threadedly connected to the slide bar 201. A second motor is fixedly connected to the slide bar 201. The output shaft of the second motor is fixedly connected to the drive roller 202. A third motor is fixedly connected to the connecting plate 701. A second lead screw is fixedly connected to the output shaft of the third motor. The second lead screw is threadedly connected to the changing seat 702. The connecting plate 701 is detachably connected to a freely movable robotic arm by bolts. An arc panel is fixedly connected to the changing seat 702.

[0029] During the winding process, the protrusion on the drive roller 202 is inserted into the slot on the driven roller 301. The drive roller 202 and the driven roller 301 are concentric, and the clamping head 302 slides on the driven roller 301 until it contacts one end of the roll. This allows the clamping head 302 and the drive roller 202 to cooperate in clamping both ends of the roll. During the winding process, the drive roller 202 rotates continuously. Through the cooperation of the protrusion and the slot, the driven roller 301 rotates synchronously with the drive roller 202 on the base frame 101. This causes the roll to rotate continuously under the clamping of the drive roller 202 and the clamping head 302. This allows the nonwoven fabric transported by the equipment in front to gradually wind and wind onto the roll on the drive roller 202, thus completing the winding process.

[0030] When the winding thickness of a roll reaches its maximum, the nonwoven fabric between the roll and the preceding equipment is first cut, causing the drive roller 202 to rotate until the protrusion on the drive roller 202 is in a vertical position. Then, the clamping head 302 is operated to slide continuously on the driven roller 301 until it is fully within the range of the driven roller 301. Next, the slide bar 201 is slid upwards, thereby lifting the drive roller 202 and the completed roll on it until the drive roller 202 and the arc panel on the changing seat 702 are concentric. Then, the changing seat 702 is operated to slide until it moves to a position below the roll on the drive roller 202. Finally, the clamping arc plate 704 is operated to slide, thereby aligning the clamping arc plate 704 with the... The changing seat 702 clamps the roll, and then the changing seat 702 slides in the opposite direction to remove the completed roll from the drive roller 202. Then, the robot moves to place the collected rolls in a certain position. At the same time, multiple new rolls to be used are placed within the robot's movement range. By sliding the clamping arc plate 704 again in conjunction with the movement of the robot, a new roll to be wound is clamped and the connecting plate 701 is reset. Then, the changing seat 702 slides again to put the new unwound roll onto the drive roller 202. Then, the slide bar 201 is reset to perform the subsequent winding work, thereby facilitating the automatic replacement of the wound nonwoven fabric rolls.

[0031] See Figure 6-7 The diagram illustrates an embodiment of the invention that facilitates cutting of the nonwoven fabric when the roll needs to be changed. Further,

[0032] The system also includes a cutter 501 slidably connected to a base frame 101. A cutting seat I 102 is fixedly connected to the base frame 101, and a cutting seat II 103 is connected to the cutting seat I 102. A first electric push rod capable of pushing the cutter 501 to slide is provided on the base frame 101. A cutting groove is provided on both the cutting seat I 102 and the cutting seat II 103, and the cutter 501 can be inserted into the cutting groove.

[0033] When the roll needs to be replaced, first operate the cutter 501 to slide downward, so that the cutter 501 presses down on the non-woven fabric between the roll and the front conveyor, and cooperates with the cutting grooves on the cutting seat I 102 and the cutting seat II 103 to cut the non-woven fabric between the roll and the front conveyor, thereby facilitating the subsequent replacement work.

[0034] See Figure 6 The diagram shows a schematic of the facilitating sliding of the clamping head 302 according to the present invention, further.

[0035] The device also includes a pressure roller 502 slidably connected to the cutter 501. A spring I 503 is fixed between the pressure roller 502 and the cutter 501. Multiple springs II 303 are fixed between the clamping head 302 and the base frame 101. An electromagnetic block capable of attracting the pressure roller 502 is provided on the spring I 503. The elastic force of the spring I 503 is less than the elastic force provided by the multiple springs II 303. A rubber plug is provided at the rotatable connection between the driven roller 301 and the base frame 101. The rubber plug can increase the rotational friction of the driven roller 301, making it less likely for the driven roller 301 to rotate when it is not driven by the drive roller 202.

[0036] Multiple springs II 303 enable the clamping head 302 to press firmly against the drum when no other external force is applied, thereby providing clamping force;

[0037] During the cutting operation, the cutter 501 slides downwards. Since the elastic force of spring I 503 is less than the elastic force provided by multiple springs II 303, spring I 503 can slide on the cutter 501. Therefore, the clamping head 302 will not be driven to slide during the cutting operation, ensuring that the clamping head 302 can provide clamping force to the drum, which facilitates the cutting operation. After the cutting operation is completed, the cutter 501 is slid upwards to reset, and then the electromagnetic block on spring I 503 is activated to attract the pressure roller 502. Then the cutter 501 slides downwards again, so that the pressure roller 502 moves synchronously with the cutter 501. This causes the pressure roller 502 to press the clamping head 302, so that the clamping head 302 overcomes the elastic force provided by multiple springs II 303 and slides on the driven roller 301. This allows the clamping head 302 to gradually slide into the range of the driven roller 301, that is, to completely disengage from the drive roller 202, which facilitates the subsequent operation of the slider 201 sliding upwards to change the drum.

[0038] See Figure 4-6 A schematic diagram illustrating the method for conveniently applying adhesive to an unwound roll according to the present invention is shown. Further,

[0039] The clamping arc plate 704 in this device is provided with two drip grooves 703, and multiple nozzles for dripping adhesive are connected directly above the positions of the two drip grooves 703 on the clamping arc plate 704.

[0040] The two drip grooves 703 allow multiple nozzles to be activated after a brand new roll to be wound up is clamped using the replacement seat 702 and the clamping arc plate 704. The adhesive is then dripped onto the roll through the two drip grooves 703. After the brand new roll is moved back to its original position, the cut non-woven fabric is pasted onto the roll, and the roll is then rotated to automatically complete the collection task again, ensuring the continuity of processing.

[0041] See Figure 7 , Figure 10A schematic diagram of an embodiment of the invention, which facilitates the bonding of cut nonwoven fabric to a roll, is shown. Further,

[0042] The device also includes a rotating rod 601 rotatably connected to the base frame 101. The base frame 101 is equipped with a fourth motor that can drive the rotating rod 601 to rotate. The rotating rod 601 has a hollow structure inside and a slot is opened on the rotating rod 601. An air pump is connected to the outside of the rotating rod 601.

[0043] After placing the new roll to be wound onto the drive roller 202 and resetting the slide bar 201, the cutter 501 is lifted upwards again, thereby resetting the clamping head 302 and forming a new roll. Figure 2 As shown in the posture, the drive roller 202 is then rotated to rotate the side with the adhesive applied to the position facing the rotating rod 601;

[0044] After the nonwoven fabric is cut using the cutter 501, the cut nonwoven fabric will naturally fall onto the cutting seat I102 and the rotating rod 601. At this time, the air pump on the rotating rod 601 is started to create negative pressure, which fixes the nonwoven fabric on the rotating rod 601. After the drive roller 202 with the new roll to be rolled is reset, the rotating rod 601 is rotated, which causes the nonwoven fabric on the rotating rod 601 to adhere to the roll on the drive roller 202. Then the power to the air pump is turned off, which causes the nonwoven fabric to no longer be fixed by the rotating rod 601. The rotating rod 601 presses the nonwoven fabric to adhere to the roll for a period of time, so that the nonwoven fabric comes into contact with the adhesive and completes the bonding.

[0045] Referring to 7, a schematic diagram is shown of an embodiment that provides space for the rotation of the lever 601 according to the present invention. Further,

[0046] In this device, the cutting seat II 103 is slidably connected to the cutting seat I 102, and a second electric push rod that can push the cutting seat II 103 to slide is fixed on the cutting seat I 102.

[0047] Before the rotating rod 601 rotates, the cutting seat II 103 is first operated to slide inside the cutting seat I 102, so that the cutting seat II 103 is retracted into the cutting seat I 102, which facilitates the subsequent rotation of the rotating rod 601.

[0048] See Figure 3 The diagram illustrates an embodiment of the invention that facilitates the unfolding of wrinkles generated during the winding process. Further,

[0049] The device also includes a bonding roller 401 that is slidably connected to the slide bar 201. A spring Ⅲ 402 is fixed between the bonding roller 401 and the slide bar 201. One side of the bonding roller 401 is provided with an arc-shaped surface 406.

[0050] During the winding process, after collecting for several weeks, as the number of nonwoven fabric layers increases, the nonwoven fabric will gradually come into contact with the bonding roller 401. As a result, the bonding roller 401 is pressed against the surface of the nonwoven fabric by the elastic force of the spring III 402. In the subsequent winding process, the bonding roller 401 can always be in contact with the nonwoven fabric, which makes it easier to unfold the wrinkles generated during the winding process.

[0051] The curved surface 406 allows the roll to naturally press the bonding roller 401 onto the slide bar 201 when it comes into contact with the curved surface 406 during installation, thus preventing the roll from being blocked by the bonding roller 401 and affecting the installation.

[0052] See Figure 8 The diagram illustrates an embodiment of the invention for improving the adhesion between nonwoven fabric and roll, further...

[0053] The device also includes a vertical plate 602 slidably connected to the base frame 101, a striking head 603 fixedly connected to the vertical plate 602, a circular plate 405 fixedly connected to the bonding roller 401, a fifth motor fixedly connected to the base frame 101, a third lead screw fixedly connected to the output shaft of the fifth motor, and the third lead screw threadedly connected to the vertical plate 602.

[0054] After using the rotating rod 601 to bond the cut nonwoven fabric to the drive roller 202 for a period of time, the drive roller 202 is rotated, which causes the roll to gradually begin the winding task. When the nonwoven fabric bonded to the drive roller 202 rotates to a position relative to the bonding roller 401, the vertical plate 602 can be operated to slide back and forth on the base frame 101, which causes the striking head 603 to press the circular plate 405, causing the bonding roller 401 to slide back and forth on the base frame 101, which in turn causes the bonding roller 401 to squeeze the area multiple times, making it completely bonded to the surface of the roll, thereby further improving the bonding effect.

[0055] Referring to the figures, an intention is shown for an embodiment according to the invention that further facilitates periodic replacement of the reel; furthermore,

[0056] The device also includes an inclined plate 404 fixed to the bonding roller 401, and a pressure sensor is provided on the surface of the striking head 603.

[0057] As the number of winding layers increases, the bonding roller 401 will gradually slide on the slide bar 201 against the elastic force of the spring Ⅲ 402. The winding thickness can be determined by measuring the sliding distance of the bonding roller 401.

[0058] According to the winding thickness requirements of a unified batch of rolls, the staff can adjust the position of the vertical plate 602, thereby adjusting the positional relationship between the striking head 603 and the inclined plate 404. When the bonding roller 401 moves to a predetermined position on the inclined plate 404 and contacts the striking head 603, the pressure sensor on the striking head 603 can receive a signal, and then the roll changing work can begin. That is, by adjusting the position of the vertical plate 602, the winding thickness specification can be adjusted, thus facilitating the winding of rolls with different thicknesses and layers according to production needs.

[0059] The nonwoven fabric processing system described above is used to process nonwoven fabrics, and the method includes the following steps:

[0060] S1. The drive roller 202 rotates on the slide bar 201, and the protrusion on the drive roller 202 cooperates with the slot on the driven roller 301 to drive the driven roller 301 to rotate, so that the drum on the drive roller 202 rotates continuously with the drive roller 202 under the clamping of the clamping head 302 and the drive roller 202.

[0061] S2. When a roll on the drive roller 202 reaches the target thickness, the cutter 501 is operated to slide downward, so that the cutter 501 is inserted into the cutting groove on the cutting seat I 102 and the cutting seat II 103.

[0062] S3. Reset the cutter 501 and activate the electromagnetic block on the cutter 501. Then slide the cutter 501 again so that the pressure roller 502 presses the clamping head 302, and the clamping head 302 slides on the driven roller 301 against the elastic force of multiple springs II 303.

[0063] S4. Slide the slide bar 201 to move the drive roller 202 to a position concentric with the arc panel on the replacement seat 702;

[0064] S5. Slide the change seat 702 until it moves to the position where it coincides with the drum on the drive roller 202. Then slide the clamping arc plate 704 downward so that the clamping arc plate 704 and the change seat 702 clamp the drum.

[0065] S6. Operate the replacement seat 702 again to slide and remove the roll from the drive roller 202, and coordinate with the robotic arm of the connecting plate 701 to move and place the removed roll.

[0066] S7. Move the robotic arm connecting the connecting plate 701 and slide it in conjunction with the clamping arc plate 704, thereby putting a brand new roll of roll to be used back onto the drive roller 202, and dripping adhesive onto the roll through the two dripping grooves 703.

[0067] S8. Reset the slide bar 201 and slide the clamping head 302 back. Then rotate the drive roller 202 so that the side with the adhesive applied faces the rotating rod 601. Then rotate the rotating rod 601 so that the rotating rod 601 adheres the nonwoven fabric to the position on the drive roller 202 where the adhesive is applied, thereby connecting the nonwoven fabric to the drive roller 202 for subsequent winding.
