DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The production process of knitted fabrics includes the following production steps: S1. Choose yarns containing polyester or fluorinated fibers, and clean, dry and adjust the tension of the yarns; choose yarns containing polyester or fluorinated fibers, which have natural anti-fouling and waterproof properties. Polyester fibers have low water absorption and can effectively reduce the adhesion of stains and liquids on the surface of the yarns.

[0021] S2. Introduce the processed yarn into the knitting machine, and weave the yarn into knitted fabric through the weaving program; weaving the yarn into knitted fabric through the knitting process helps to improve the flexibility and structural strength of the fabric, ensuring that the finished product has both a comfortable softness and good durability.

[0022] S3. Dyeing the knitted fabric after weaving, coloring the fabric by dip-dyeing or spray-dyeing, and performing necessary heat-setting and softening treatments; heat-setting can also maintain the shape and dimensional stability of the fabric, and reduce deformation and shrinkage after washing.

[0023] S4. Apply antifouling coating to the knitted fabric treated in step 3 through a coating device, and after completion, allow it to dry naturally at room temperature; acrylic emulsion can be used for the antifouling coating. The natural drying method avoids high-energy consumption hot drying equipment, reduces energy consumption in the production process, and reduces damage to fabric properties, retaining its softness and breathability. It is a more environmentally friendly drying treatment method.

[0024] S5, performing anti-wrinkle treatment on the dried knitted fabric; S6, performing a quality inspection on the treated knitted fabric, and after the inspection, the knitted fabric is rolled up by a rolling device; S7. After production is completed, the rolled knitted fabric is stored in a dry and ventilated environment.

[0025] In this embodiment, reference Figure 1 The coating device includes a frame 1, a conveying roller mechanism arranged on the frame 1 and used to convey the knitted fabric 7, a cleaning mechanism arranged on the frame 1 and used to clean the surface of the knitted fabric 7, a coating mechanism arranged on the frame 1 and used to coat the surface of the knitted fabric 7 with antifouling coating, and a toggling mechanism used to toggle the surface of the knitted fabric 7 to allow the antifouling coating to penetrate; the cleaning mechanism can clean the surface of the knitted fabric 7 before it enters the coating stage, reducing the influence of dust and impurities on the surface of the knitted fabric 7 on the coating adhesion effect and uniformity. The toggling mechanism can toggle the surface of the knitted fabric 7 coated with coating, so that the coating can penetrate deeper into the fiber gap, ensuring the full combination between the coating and the yarn, thereby improving the adhesion and durability of the antifouling coating.

[0026] Specifically, refer to Figure 1-2The conveying roller mechanism includes a first conveying roller 101, a second conveying roller 102, a third conveying roller 103, a fourth conveying roller 104, a fifth conveying roller 105, and a sixth conveying roller 106 which are sequentially arranged on a frame 1 and rotatably connected to the frame 1. The first conveying roller 101 and the second conveying roller 102 are at the same level, the fifth conveying roller 105 and the sixth conveying roller 106 are at the same level, the third conveying roller 103 and the fourth conveying roller 104 are at a level lower than the level of the second conveying roller 102, the third conveying roller 103 is arranged on a side of the frame 1 close to the second conveying roller 102, and the distance between the second conveying roller 102 and the third conveying roller 103 keeps the knitted fabric in a vertical state, the first conveying roller 101 and the sixth conveying roller 106 are connected through a driving mechanism, the driving mechanism includes a second rotating motor 8 and a synchronous pulley group connected to the first conveying roller 101 and the sixth conveying roller 106, and the output end of the second rotating motor 8 is connected to the first conveying roller 101. When in use, the knitted fabric 7 can be placed on the first conveying roller 101 , and then the second rotary motor 8 is started, the second rotary motor 8 drives the first conveying roller 101 to rotate, so that the knitted fabric 7 is transported on the first conveying roller 101 .

[0027] For further reference, Figure 2-3 The cleaning mechanism includes two groups of brush roller assemblies and a first rotating motor 2. The two groups of brush roller assemblies are connected by a synchronous pulley mechanism. The two groups of brush roller assemblies have the same rotation speed. The brush roller assembly includes a cleaning roller 201 and two cleaning plates 202. Each cleaning plate 202 is arranged circumferentially with the cleaning roller 201 as the center or symmetrically with the central axis of the cleaning roller 201. A flexible brush 203 is arranged on the side of the cleaning plate 202 away from the cleaning roller 201, and the surface of the flexible brush 203 abuts against the knitted fabric 7. A support frame 204 is arranged on the side of the frame 1 close to the second conveying roller 102. The cleaning roller 201 is rotatably connected to the support frame 204. The cleaning roller 201 is connected to the cleaning plate 202 through a plurality of connecting rods 205. The cleaning plates 202 in the two groups of brush roller assemblies are arranged in an interlaced manner, and the output end of the first rotating motor 2 is fixedly connected to the cleaning roller 201. The interlaced cleaning plates 202 can ensure that the two brush roller assemblies clean the surface of the knitted fabric 7 more comprehensively, reducing the possibility of cleaning dead corners.

[0028] Specifically, a beating mechanism for knocking off dust on the surface of the flexible brush 203 is provided at the bottom of each brush roller assembly, and the beating mechanism includes an arc gear 3 (the arc gear 3 has only one section), a spur gear 301, a clapper 302, and an arc collecting box 303. The arc gear 3 is fixedly connected to the cleaning roller 201, and the arc gear 3 is arranged on the side of the cleaning plate 202 away from the second conveying roller 102. The clapper 302 is rotatably connected to the support frame 204 through a first rotating shaft 304, and a torsion spring 305 is sleeved on the first rotating shaft 304. The spur gear 301 is arranged on the first rotating shaft 304 and fixedly connected to the first rotating shaft 304. The arc gear 3 is meshed with the spur gear 301. The arc collecting box 303 is arranged at the bottom of the clapper 302, and the arc collecting box 303 is fixedly connected to the support frame 204, and the clapper 302 abuts against the surface of the flexible brush 203.

[0029] The flapping mechanism can ensure that the flexible brush 203 can be cleaned in time in each cleaning cycle. This synchronization ensures that the flexible brush 203 always maintains the best cleaning state, avoids the decrease in cleaning effect caused by dust accumulation on the surface of the flexible brush 203, and ensures the uniformity and consistency of the knitted fabric cleaned by the flexible brush 203 each time. Secondly, the arc gear 3 is fixedly connected to the cleaning roller 201, and the existing rotational motion of the cleaning roller 201 is used to drive the flapping action, which reduces the manufacturing cost without the need for an additional power source. In addition, the arc-shaped collection box 303 arranged at the bottom of the flapping mechanism can effectively collect dust and impurities that fall off during the flapping process, avoid these impurities from spreading around the equipment, and reduce pollution to the working environment. At the same time, the design of the collection box is convenient for centralized dust cleaning.

[0030] When the knitted fabric 7 moves between the second conveying roller 102 and the third conveying roller 103, the first rotating motor 2 is started to drive the cleaning roller 201 to rotate, and then drive the cleaning plate 202 to rotate. The bristles on the cleaning plate 202 will clean the dust on the surface of the knitted fabric 7. At the same time, another set of brush roller components rotate synchronously to avoid cleaning dead corners. When the bristles on the cleaning plate 202 are separated from the surface of the knitted fabric 7, the arc gear 3 on the cleaning roller 201 will mesh with the spur gear 301, and the spur gear 301 drives the first rotating shaft 304 to rotate, and the clapper 302 rotates accordingly. At the same time, the torsion spring 305 will twist and accumulate force. When the arc gear 3 is separated from the spur gear 301, the torsion spring 305 quickly recovers its deformation, driving the rotating shaft to rotate in the opposite direction, so that the clapper 302 slaps the surface of the flexible brush 203, and the dust that is slapped will automatically fall into the arc collection box 303, which is convenient for the staff to collect.

[0031] In this embodiment, reference Figure 4The coating mechanism includes a cylinder 4, a sliding plate 401, a gantry 402 and two coating bins 403. The front and rear sides of the frame 1 are fixedly connected with first support blocks 404, and the first support blocks 404 are arranged between the fifth conveying roller 105 and the sixth conveying roller 106. Each first support block 404 is provided with a moving groove 405. The sliding plate 401 is slidingly connected to the inner wall of the moving groove 405. The bottom of the sliding plate 401 is connected to the telescopic rod of the cylinder 4. The bottom of the cylinder 4 is fixedly connected to the frame 1. The gantry 402 is arranged on the top of the sliding plate 401 and is connected to the bottom of the sliding plate 401 through a plurality of guide rods. 406 is fixedly connected to the sliding plate 401, the paint bin 403 is arranged on the gantry 402, an injection pipe 407 is provided on one side of the paint bin 403, and an opening is provided at the bottom of the paint bin 403 for discharging the anti-fouling paint. The injection pipe 407 can be connected to an external feeding device, so that the anti-fouling paint enters the paint bin 403 through the injection pipe 407 and is then discharged from the bottom opening. A bottom plate 408 is provided on the top of the first support block 404, and the position of the bottom plate 408 corresponds to the position of each paint bin 403. A moving mechanism for reciprocating the paint bin 403 is provided on the gantry 402.

[0032] When the knitted fabric 7 moves between the bottom plate 408 and the gantry 402, the cylinder 4 is started, and the telescopic rod of the cylinder 4 pulls the sliding plate 401 downward, so that it moves downward along the inner wall of the moving groove 405. The sliding plate 401 drives the gantry 402 to move downward through a plurality of guide rods 406, and the coating bin 403 drives the bottom of the knitted fabric 7 to contact the bottom plate 408, and the coating bin 403 evenly applies the anti-fouling coating on the surface of the knitted fabric 7. The provided moving mechanism can ensure that the coating bin 403 evenly coats the surface of the knitted fabric 7, thereby improving the consistency of coating.

[0033] Specifically, refer to Figure 5The moving mechanism includes two sets of sliding components, a second rotating shaft 5 and a first servo motor 501. The sliding components include a moving plate 502, a rotating plate 503 and an elastic member 504. The second rotating shaft 5 is rotatably connected to the inner walls of both sides of the gantry 402. The output end of the first servo motor 501 is fixedly connected to the second rotating shaft 5. The rotating plate 503 is fixedly connected to the second rotating shaft 5. The moving plate 502 is arranged on the second rotating shaft 5 through a rotating cylinder 505, and the rotating cylinder 505 is slidingly connected to the second rotating shaft 5. A plurality of push rods are provided on the side of the rotating plate 503 away from the first servo motor 501. 506, and each push rod 506 has a different height, the movable plate 502 is tilted, and one end of the movable plate 502 is in conflict with the low push rod 506 (the two are only in contact relationship), the gantry 402 is fixedly connected with an extrusion plate 508, the second rotating shaft 5 is rotatably connected to the extrusion plate 508, one end of the elastic member 504 is in conflict with the extrusion plate 508 (the two are only in contact relationship), the other end of the elastic member 504 is in conflict with the side of the rotating cylinder 505 (the two are only in contact relationship), and each paint bin 403 is connected to the corresponding rotating cylinder 505 through a connecting block 507.

[0034] When the paint bin 403 contacts the surface of the knitted fabric 7, the staff starts the first servo motor 501, and the output end of the first servo motor 501 drives the second rotating shaft 5 to rotate. The second rotating shaft 5 drives the rotating plate 503 to rotate, and the push rods 506 on the rotating plate 503 also rotate synchronously. Since the heights of the push rods 506 are different and the movable plate 502 is tilted, when the rotating plate 503 drives the push rods 506 to rotate, the movable plate 502 will move in the direction of the compressed elastic member 504 under the action of the push rods 506. At the same time, the movable plate 502 drives the rotating cylinder 505 to move along the axial direction of the second rotating shaft 5, thereby moving the paint bin 403. When the lower push rod 506 contacts the movable plate 502, the elastic member 504 will reset, driving the rotating cylinder 505 to move in the opposite direction, realizing the reciprocating movement of the paint bin 403, thereby achieving the effect of uniform coating.

[0035] The moving mechanism in this embodiment can realize the reciprocating movement of the paint bin 403 only by rotating the first servo motor 501 in one direction, avoiding frequent motor starting, stopping and reverse movement, reducing energy consumption and motor load fluctuation, and thus increasing the service life of the first servo motor 501.

[0036] Secondly, refer to Figure 6In order to make the transition between the push rod 506 and the moving plate 502 smoother, the side of each push rod 506 away from the rotating plate 503 is designed to be an arc-shaped structure. The push rod 506 with an arc-shaped structure can reduce the contact area with the moving plate 502, thereby reducing friction, making the transition between the moving plate 502 and each push rod 506 smoother, thereby improving the stability of the movement of the moving plate 502.

[0037] In addition, in order to prevent the second rotating shaft 5 from driving the rotating cylinder 505 to rotate when rotating, a rotating groove 509 is provided inside the rotating cylinder 505, and a rolling bearing 510 is provided inside the rotating groove 509. The outer ring of the rolling bearing 510 is fixedly connected to the inner wall of the rotating groove 509, and the inner ring of the rolling bearing is slidably connected to the second rotating shaft 5 (the two may only be in contact). The provision of the rolling bearing 510 can prevent the second rotating shaft 5 from driving the rotating cylinder 505 to rotate when rotating, thereby further improving the stability of the movement of the moving plate 502.

[0038] In this embodiment, reference Figure 7-9 The toggle mechanism includes a second servo motor 6, a rotating disk 601, a fixed block 602, an eccentric column 603, a spherical rotating block 604, and a toggle disk 605. The frame 1 is fixedly connected with a second support block 606 between the first support block 404 and the sixth guide roller. A fixed frame 607 is fixedly connected to the side of the frame 1 close to the second support block 606. The second servo motor 6 is fixedly connected to the side of the second support block 606. The output end of the second servo motor 6 is fixedly connected with a third rotating shaft 608, and the third rotating shaft 608 is rotatably connected to the fixed frame 607. The rotating disk 601 is arranged on the side of the third rotating shaft 608 away from the second servo motor 6. The eccentric column 603 is arranged on the rotating disk 601 and is eccentrically arranged. A receiving groove 609 is provided on the fixed frame 607, and a toggle rod 610 is provided in the receiving groove 609. The central axis of the toggle rod 610 is perpendicular to the central axis of the third rotating shaft 608. The toggle rod 610 is fixedly connected to the fixed block 602. A spherical groove 611 is provided on the side of the fixed block 602 close to the servo motor. The spherical rotating block 604 is arranged on the side of the eccentric column 603 away from the rotating disk 601. The spherical rotating block 604 is slidably connected to the inner wall of the spherical groove 611, and the toggle disk 605 is fixedly connected to the toggle rod 610.

[0039] When the knitted fabric 7 moves onto the toggle plate 605, the staff starts the second servo motor 6 to rotate it at high speed. The output end of the second servo motor 6 will drive the third rotating shaft 608 to rotate, and the third rotating shaft 608 will drive the rotating plate 601 to rotate. The rotating plate 601 drives the eccentric column 603 to rotate, and the eccentric column 603 drives the spherical rotating block 604 to rotate. Due to the eccentric setting of the eccentric column 603, the spherical rotating block 604 will slide in the spherical groove 611 under the drive of the eccentric column 603, and make the fixed block 602 shake up and down, and the fixed block 602 further drives the toggle rod 610 to shake up and down, so that the toggle plate 605 can toggle the passing fabric, so that the anti-fouling paint can penetrate into the knitted fabric. In addition, while the toggle rod 610 is shaking up and down, it also moves back and forth along the inner wall of the accommodating groove 609, and at the same time drives the toggle plate 605 to reciprocate, ensuring that the bottom area of ​​the knitted fabric can be affected by the toggle effect, ensuring that the paint penetrates more evenly in the gaps between the knitted fabric fibers, and reducing the possibility of uneven penetration or missing areas that may be caused by toggling at a fixed position.

[0040] In this embodiment, a plurality of toggle posts 612 are provided on the toggle plate 605, and the top of each toggle post 612 is designed to be an arc-shaped structure. The uniform distribution of the plurality of toggle posts 612 can toggle the knitted fabric 7 in a larger range, thereby improving the coverage rate and working efficiency of the entire toggle area, and ensuring that all parts of the knitted fabric 7 can be fully treated with paint penetration. Secondly, compared with a flat or pointed design, the arc-shaped toggle post 612 can better protect the fiber, avoid fuzzing, damage or deformation caused by the contact between the toggle post 612 and the knitted fabric, thereby reducing damage to the knitted fabric.

[0041] Working principle: When in use, the knitted fabric 7 is placed on the conveying roller mechanism and the second rotary motor 8 is started for conveying. When the knitted fabric 7 passes through the cleaning mechanism, the first rotary motor 2 is started to drive the cleaning roller 201 to rotate, and then drive the cleaning plate 202 to rotate. The bristles on the cleaning plate 202 will clean the dust on the surface of the knitted fabric 7. At the same time, another set of brush roller components rotate synchronously to avoid cleaning dead corners. When the bristles on the cleaning plate 202 are separated from the surface of the knitted fabric 7, the arc gear 3 on the cleaning roller 201 will mesh with the spur gear 301, and the spur gear 301 drives the first rotating shaft 304 to rotate, and the clapper 302 rotates accordingly. At the same time, the torsion spring 305 will be twisted and accumulate force. When the arc gear 3 is separated from the spur gear 301, the torsion spring 305 quickly recovers its deformation, driving the rotating shaft to rotate in the opposite direction, so that the clapper 302 slaps the surface of the flexible brush 203, and the dust that is slapped will automatically fall into the arc collection box 303, which is convenient for the staff to collect.

[0042] When the knitted fabric 7 enters the coating process, the cylinder 4 is started, and the telescopic rod of the cylinder 4 will pull the sliding plate 401 downward, so that it moves downward along the inner wall of the moving groove 405. The sliding plate 401 drives the gantry 402 to move downward through a plurality of guide rods 406, and the coating bin 403 drives the bottom of the knitted fabric 7 to contact the bottom plate 408, and the coating bin 403 will evenly apply the anti-fouling coating on the surface of the knitted fabric 7. In addition, the staff starts the first servo motor 501, and the output end of the first servo motor 501 drives the second rotating shaft 5 to rotate. The second rotating shaft 5 drives the rotating plate 503 to rotate, and the various push rods 506 on the rotating plate 503 also rotate synchronously. Since the heights of the push rods 506 are different and the moving plate 502 is tilted, when the rotating plate 503 drives the push rods 506 to rotate, the moving plate 502 will move in the direction of the compression elastic member 504 under the action of the push rods 506. At the same time, the moving plate 502 drives the rotating cylinder 505 to move along the axis direction of the second rotating shaft 5, thereby moving the paint bin 403. When the lower push rod 506 contacts the moving plate 502, the elastic member 504 will reset, driving the rotating cylinder 505 to move in the opposite direction, realizing the reciprocating movement of the paint bin 403, thereby achieving a uniform coating effect.

[0043] When the knitted fabric 7 passes through the toggle mechanism, the staff starts the second servo motor 6 to rotate it at high speed. The output end of the second servo motor 6 will drive the third rotating shaft 608 to rotate, and the third rotating shaft 608 will drive the rotating disk 601 to rotate. The rotating disk 601 drives the eccentric column 603 to rotate, and the eccentric column 603 drives the spherical rotating block 604 to rotate. Due to the eccentric setting of the eccentric column 603, the spherical rotating block 604 will slide in the spherical groove 611 driven by the eccentric column 603, and make the fixed block 602 shake up and down, and the fixed block 602 further drives the toggle rod 610 to shake up and down, so that the toggle disk 605 toggle the passing fabric, so that the anti-fouling coating can penetrate into the knitted fabric (because there is a distance between the toggle mechanism and the coating mechanism, when the fabric is toggled, it will not affect the coating of the fabric). In addition, while the toggle rod 610 is shaking up and down, it also reciprocates along the inner wall of the accommodating groove 609, and drives the toggle plate 605 to reciprocate, ensuring that the bottom area of ​​the knitted fabric can be toggled, ensuring that the paint penetrates more evenly in the gaps between the knitted fabric fibers, and reducing the possibility of uneven penetration or missing areas that may be caused by toggling at a fixed position. Secondly, the toggle mechanism can shake off the non-sticky dust at the bottom of the fabric, improving the cleanliness of the fabric.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
