Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric production technology, specifically to a production apparatus and method for using highly absorbent and abrasion-resistant spunlace nonwoven fabric. Background Technology

[0002] Spunlace nonwoven fabric is a type of nonwoven fabric produced by using multiple micro-jet water jets sprayed from a spunlace head to penetrate the fiber web layer. The water jets are then refracted and reflected by a wire mesh curtain or roller located below the fiber web layer, causing the fibers within the fiber web to become entangled. Subsequent drying treatment completes the process. Highly absorbent and abrasion-resistant spunlace nonwoven fabric is used in various fields such as medical and clothing manufacturing due to its excellent moisture absorption and abrasion resistance.

[0003] In the manufacturing process of highly absorbent and abrasion-resistant spunlace nonwoven fabrics, drying is required. Currently, the rollers used for drying these fabrics are mostly closed cylinders. This prevents the fabric from being quickly dried from inside the rollers during transport, resulting in poor drying efficiency. Furthermore, different specifications of highly absorbent and abrasion-resistant spunlace nonwoven fabrics have different basis weights, leading to varying fabric thicknesses. Therefore, gaps need to be reserved on the rollers for hot air to pass through, and these gaps need to be adjustable to accommodate the rapid drying of different specifications of highly absorbent and abrasion-resistant spunlace nonwoven fabrics. To address these issues, the inventors propose a production apparatus and method for using highly absorbent and abrasion-resistant spunlace nonwoven fabrics to solve these problems. Summary of the Invention

[0004] To address the current limitations of closed cylindrical rollers used in drying highly absorbent and abrasion-resistant spunlace nonwoven fabrics, which prevent rapid drying of the fabric from within the rollers during transport and result in low drying efficiency, and to further address the issue of varying fabric thicknesses due to different weights of the fabric, the present invention aims to provide a production apparatus and method for producing highly absorbent and abrasion-resistant spunlace nonwoven fabrics.

[0011] Preferably, the rotating mechanism includes two second support frames, which are fixedly installed on the top of the base and located between two first support frames.

[0013] Preferably, the two slide rods are provided with two slide rails on their outer rings, and support seats are fixedly installed on the two slide rails. The support seats are slidably mounted on the two first annular brackets. Two fixed seats are fixedly installed at the end of the support seat away from the second annular bracket.

A sleeve is provided in the middle of the fixed rod, and the sleeve is located between the two rotating cylinders.

[0014] A method of using a production apparatus for highly absorbent and highly abrasion-resistant spunlace nonwoven fabric includes the following steps;

[0015] Step 1: Start the first motor to drive the first drive shaft to rotate. The rotation of the first drive shaft drives the transmission shaft to rotate, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft causes the two moving discs on its bidirectional thread to move towards each other. The movement of the two moving discs towards each other causes the hinge seats connected to them to move towards each other. The movement of the two hinge seats towards each other causes the first and second support arms connected to them to deflect around the central axis, so that the slide rods at the other end of the first and second support arms slide inside the slide rail, and cause the support seat connected to the slide rail to slide on the two first annular brackets, thereby adjusting the distance between the support seat and the second annular bracket. The movement of the support seat causes the sleeve on the outer ring of the fixed rod on it to move, so that the distance between the several annularly distributed sleeves can be adjusted. The roller formed by the several annularly distributed sleeves can produce gaps of different sizes, which is convenient for drying high absorbency and wear-resistant spunlace nonwoven fabrics of different thicknesses.

[0016] Step 2: The highly absorbent and abrasion-resistant spunlace nonwoven fabric is wound around the outer ring of a roller consisting of several annularly distributed sleeves. The second motor drives the second drive shaft to rotate. The rotating cylinder located below is connected to the second drive shaft through a transmission belt and a transmission wheel. The rotation of the second drive shaft drives the several rotating cylinders located below to rotate. The rotation of the rotating cylinders drives the outer toothed ring of their outer ring to rotate. The rotation of the outer toothed ring drives the outer gear and another outer toothed ring above it to rotate. Thus, the rotation of the several rotating cylinders drives the rotation of several adjustment mechanisms. The rotation of the adjustment mechanisms assists in transporting the highly absorbent and abrasion-resistant spunlace nonwoven fabric.

[0017] Step 3: Hot air is discharged into the main pipe, and then enters the air outlet pipe through the connecting pipe and the fixed pipe. It is then discharged through the air hole of the air outlet pipe and arrives at the gap of the roller composed of several sleeves to quickly dry the highly absorbent and wear-resistant spunlace nonwoven fabric.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The present invention sets up a first driving mechanism, a drying mechanism and an adjusting mechanism, so that the first driving mechanism can drive the drying mechanism to work, and then uses some components of the drying mechanism to drive the adjusting mechanism to operate, so that the gap between the sleeves of several adjusting mechanisms can be adjusted, thereby facilitating the drying of highly absorbent and wear-resistant spunlace nonwoven fabrics of different thicknesses.

[0020] 2. In this invention, the rotation of the first drive shaft drives the rotation of the transmission shaft, which in turn drives the rotation shaft to rotate. The rotation shaft then drives the moving disc on it to move, which in turn drives the adjustment mechanism to operate. This causes the first and second support arms of the adjustment mechanism to deflect, and the sleeves on the outer ring of the fixed rod on the support seat that is slidably connected to the other ends of the first and second support arms to move accordingly. This allows the roller formed by several sleeves arranged in a ring to produce gaps of different sizes, which facilitates the drying of highly absorbent and abrasion-resistant spunlace nonwoven fabrics of different thicknesses from inside the roller.

[0021] 3. This invention utilizes the rotation of a second drive shaft to drive several rotating cylinders to rotate, and the rotation of the rotating cylinders to drive several adjusting mechanisms to rotate, thereby assisting in the conveying of the highly absorbent and abrasion-resistant spunlace nonwoven fabric. By discharging hot air into the air outlet pipe through the main pipe, connecting pipe and fixed pipe, and then discharging it through the air holes of the air outlet pipe, the highly absorbent and abrasion-resistant spunlace nonwoven fabric is quickly dried.

The rotating cylinder 502 located below is connected to the second drive shaft 302 through a transmission belt and a transmission wheel.

[0046] By adopting the above technical solution, the rotation of the second drive shaft 302 can drive the rotating cylinder 502 to rotate.

[0047] The adjusting mechanism 6 includes two sets of connecting components. The two sets of connecting components are respectively located on the outer rings of the two rotating rings 415 of the outer ring of the two bidirectional threads 408. Each connecting component includes two hinge seats 601, and the two hinge seats 601 are slidably disposed on the second annular bracket 507.

[0048] By adopting the above technical solution, the movement of the movable disk 410 can drive the first support arm 602 and the second support arm 603 to deflect.

[0049] Two slide rails 606 are provided on the outer ring of the two slide rods 605. Support seats 607 are fixedly installed on the two slide rails 606, and the support seats 607 are slidably arranged on the two first annular brackets 506.

[0050] By adopting the above technical solution, the deflection of the first support arm 602 and the second support arm 603 can drive the sleeve 610 to move.

[0051] A method of using a production apparatus for highly absorbent and highly abrasion-resistant spunlace nonwoven fabric includes the following steps;

[0052] Step 1: Start the first motor 203, which drives the first drive shaft 202 to rotate. The rotation of the first drive shaft 202 drives the transmission shaft 403 to rotate, which in turn drives the rotating shaft 406 to rotate. The rotation of the rotating shaft 406 causes the two movable disks 410 on its bidirectional thread 408 to move towards each other. The movement of the two movable disks 410 towards each other causes the hinge seats 601 connected to them to move towards each other. The movement of the two hinge seats 601 towards each other causes the first support arm 602 and the second support arm 603, which are hinged to each other, to deflect around the central axis 604, causing the first support arm 602 and the second support arm 603 to deflect. The slide bar 605 at the other end of the support arm 603 slides inside the slide rail 606, and drives the support seat 607 connected to the slide rail 606 to slide on the two first annular brackets 506, thereby adjusting the distance between the support seat 607 and the second annular bracket 507. The movement of the support seat 607 drives the sleeve 610 on the outer ring of the fixed rod 609 on it to move, so that the distance between the several annularly distributed sleeves 610 can be adjusted. The roller formed by the several annularly distributed sleeves 610 can produce gaps of different sizes, which is convenient for drying high absorbency and wear-resistant spunlace nonwoven fabrics of different thicknesses.

[0053] Step 2: The highly absorbent and abrasion-resistant spunlace nonwoven fabric is wound around the outer ring of a roller consisting of several annularly distributed sleeves 610. The second motor 303 drives the second drive shaft 302 to rotate. The rotating cylinder 502 located below is connected to the second drive shaft 302 through a transmission belt and a transmission wheel. The rotation of the second drive shaft 302 drives the several rotating cylinders 502 located below to rotate. The rotation of the rotating cylinders 502 drives the outer toothed ring 504 of its outer ring to rotate. The rotation of the outer toothed ring 504 drives the outer gear 505 above it and another outer toothed ring 505 to rotate. Thus, the rotation of the several rotating cylinders 502 drives the rotation of several adjusting mechanisms 6. The rotation of the adjusting mechanisms 6 assists in transporting the highly absorbent and abrasion-resistant spunlace nonwoven fabric.

[0054] Step 3: Hot air is discharged into the main pipe 413 and enters the air outlet pipe 414 through the connecting pipe 412 and the fixed pipe 411. Then it is discharged through the air hole of the air outlet pipe 414 and arrives at the gap of the roller composed of several sleeves 610 to quickly dry the highly absorbent and wear-resistant spunlace nonwoven fabric.

[0055] Working Principle: In use, the invention utilizes a first motor 203 to drive a first drive shaft 202 to rotate. The rotation of the first drive shaft 202 drives a first bevel gear 204 to rotate, which in turn drives a third bevel gear 405 to rotate. The third bevel gear 405 then drives a transmission shaft 403 to rotate, which in turn drives a second bevel gear 404 to rotate. The second bevel gear 404 then drives a fourth bevel gear 407 to rotate, which in turn drives a rotating shaft 406 to rotate. The rotating shaft 406 then drives two bidirectional threads 408 on it to rotate. The sliding of a movable disk 410 on a fixed tube 411 causes the bidirectional threads 408 to rotate, moving the two movable disks 410 towards each other. This movement of the two movable disks 410 towards each other causes the two hinge seats 601 of the connecting assembly of the adjusting mechanism 6 to move towards each other. The two hinged seats 601 move towards each other, causing the first support arm 602 and the second support arm 603 connected to them to deflect around the central axis 604. The slide rod 605 at the other end of the first support arm 602 and the second support arm 603 slides inside the slide rail 606, and causes the support seat 607 connected to the slide rail 606 to slide on the two first annular brackets 506, thereby adjusting the distance between the support seat 607 and the second annular bracket 507. The movement of the support seat 607 causes the fixed seat 608 to move, the movement of the fixed seat 608 causes the fixed rod 609 to move, and the movement of the fixed rod 609 causes the sleeve 610 to move, so that the distance between the several annularly distributed sleeves 610 can be adjusted. The roller formed by the several annularly distributed sleeves 610 can produce gaps of different sizes, which is convenient for drying high absorbency and wear-resistant spunlace nonwoven fabrics of different thicknesses.

[0056] Highly absorbent and abrasion-resistant spunlace nonwoven fabric is wound around the outer ring of a roller consisting of several annularly distributed sleeves 610. Then, a second motor 303 drives a second drive shaft 302 to rotate. A rotating cylinder 502 located below is connected to the second drive shaft 302 via a transmission belt and a transmission wheel. The rotation of the second drive shaft 302 drives several rotating cylinders 502 located below to rotate. The rotation of the rotating cylinders 502 drives the outer toothed ring 504 of its outer ring to rotate. The rotation of the outer toothed ring 504 drives the meshing outer gear 505 to rotate. The rotation of the outer gear 505 drives the meshing outer gear 505 above it to rotate. The rotation of the outer gear 505 above drives the meshing outer toothed ring 504 and the rotating cylinders 502 to rotate. Thus, the rotating cylinders 502 can drive several adjusting mechanisms 6 to rotate. The rotation of the adjusting mechanisms 6 assists in transporting the highly absorbent and abrasion-resistant spunlace nonwoven fabric.

[0057] Hot air is discharged into the main pipe 413, and then enters the air outlet pipe 414 through the connecting pipe 412 and the fixed pipe 411. It is then discharged through the air hole of the air outlet pipe 414 and arrives at the gap of the roller composed of several sleeves 610 to quickly dry the highly absorbent and wear-resistant spunlace nonwoven fabric.

6. The method of using the production apparatus for highly absorbent and highly abrasion-resistant spunlace nonwoven fabric as described in any one of claims 1-5, characterized in that, Includes the following steps; Step 1: Start the first motor (203) to drive the first drive shaft (202) to rotate. The rotation of the first drive shaft (202) drives the transmission shaft (403) to rotate. The rotation of the transmission shaft (403) drives the rotating shaft (406) to rotate. The rotation of the rotating shaft (406) drives the two moving discs (410) on its bidirectional thread (408) to move towards each other. The movement of the two moving discs (410) towards each other drives the hinge seats (601) connected to them to move towards each other. The movement of the two hinge seats (601) towards each other drives the first support arm (602) and the second support arm (603) connected to them to deflect around the central axis (604), so that the first support arm (602) and The slide bar (605) at the other end of the second support arm (603) slides inside the slide rail (606) and drives the support seat (607) connected to the slide rail (606) to slide on the two first annular brackets (506), thereby adjusting the distance between the support seat (607) and the second annular bracket (507). The movement of the support seat (607) drives the sleeve (610) on the outer ring of the fixed rod (609) on it to move, so that the distance between the several annularly distributed sleeves (610) can be adjusted. The roller formed by the several annularly distributed sleeves (610) can produce gaps of different sizes, which is convenient for drying high absorbency and wear-resistant spunlace nonwoven fabrics of different thicknesses. Step 2: The highly absorbent and abrasion-resistant spunlace nonwoven fabric is wound around the outer ring of a roller consisting of several sleeves (610) arranged in a ring. The second motor (303) drives the second drive shaft (302) to rotate. The rotating cylinder (502) located below is connected to the second drive shaft (302) through a transmission belt and a transmission wheel. The rotation of the second drive shaft (302) can drive the rotation of several rotating cylinders (502) located below. The rotation of the rotating cylinder (502) drives the outer toothed ring (504) of its outer ring to rotate. The rotation of the outer toothed ring (504) drives the outer gear (505) above it and another outer toothed ring (504) to rotate. Thus, the rotation of several rotating cylinders (502) can drive the rotation of several adjusting mechanisms (6). The rotation of the adjusting mechanisms (6) assists in transporting the highly absorbent and abrasion-resistant spunlace nonwoven fabric. Step 3: Hot air is discharged into the main pipe (413), and then enters the air outlet pipe (414) through the connecting pipe (412) and the fixed pipe (411). It is then discharged through the air hole of the air outlet pipe (414) and arrives at the gap of the roller composed of several sleeves (610) to quickly dry the highly absorbent and wear-resistant spunlace nonwoven fabric.
