Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a process and apparatus for producing natural antibacterial functional fabrics. Background Technology

[0002] In the textile industry, as consumers become increasingly health-conscious and environmentally conscious, the demand for fabrics with natural antibacterial properties is growing. Spraying antibacterial agent solutions is a crucial step in the production process of these fabrics.

[0003] In the actual production of fabric pretreatment and spraying, there are several easily overlooked but far-reaching technical problems: First, most existing dust removal devices use suspended suction or simple air blowing. When the suction power is increased in pursuit of high cleanliness, soft textile fabrics are prone to high-frequency shaking, edge curling, or even deviation under the action of airflow. This "aerodynamic interference" not only fails to guarantee the dust removal effect, but also causes the fabric to enter the spraying process in a wrinkled state, resulting in the accumulation or missed spraying of antibacterial agents in the wrinkles, seriously affecting the consistency of the finished product.

[0004] Secondly, cotton knots, sizing spots, or electrostatically adsorbed dust on the fabric surface are often tightly bound to the fibers, making it difficult to completely remove them using only the hydrodynamic action of negative pressure airflow. The lack of pretreatment methods to mechanically and physically break down adhesion renders the dust removal process ineffective.

[0005] Third, in traditional production lines, the negative pressure exhaust from dust removal systems is typically treated as waste gas that is directly discharged into the atmosphere. However, to achieve good atomization and spraying rates, spraying systems require additional high-energy-consuming air compressors to provide the air source. This results in bulky equipment, complex piping, and low energy efficiency.

[0006] To address the aforementioned issues, this technical solution proposes a production process and apparatus for natural antibacterial functional fabrics. Summary of the Invention

[0007] The purpose of this invention is to solve the problems in existing production processes, such as fabric shaking and deformation caused by dust removal, incomplete removal of stubborn impurities, and lack of energy coupling between the dust removal and spraying air circuit systems. Therefore, this invention proposes a production process and device for natural antibacterial functional fabrics.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A manufacturing process for a natural antibacterial functional fabric includes the following steps:

[0010] S1. Place the textile fabric into the printing and dyeing machine and print the textile fabric.

[0011] S2. Prepare the antibacterial agent. Place the prepared antibacterial agent solution into the conveying mechanism and connect the conveying mechanism to the spraying equipment to supply the antibacterial agent solution to the spraying equipment.

[0012] S3. The textile fabric is fed into the spraying equipment. First, the textile fabric is dusted, and then an antibacterial agent solution is sprayed onto the textile fabric.

[0013] S4. After spraying the antibacterial agent solution onto the textile fabric, the textile fabric is rolled up.

[0014] A production apparatus, used in the production process of natural antibacterial functional fabrics as described above, includes:

[0015] A base frame, wherein a fabric inlet hole is provided on one side of the base frame;

[0016] The dust removal mechanism, mounted on the base frame, includes a vacuum suction pump, a dust filter box, a negative pressure dust collection box, and a negative pressure adsorption box. The suction end of the vacuum suction pump is connected to the dust filter box. The dust filter box is connected to the negative pressure dust collection box and the negative pressure adsorption box through a pipe. The negative pressure dust collection box is located above the textile fabric, and the negative pressure adsorption box is located below the textile fabric and has a supporting mesh plate on top.

[0017] The spraying mechanism is fixedly installed on the base frame and includes a spraying operation box, multiple external conduits, multiple internal conduits, and multiple spraying protective covers. The internal conduits are arranged inside the external conduits. One end of the internal conduit is connected to a diversion conduit, and the other end is connected to the spraying protective cover through a fixed conduit. The external conduits are connected to an air supply assembly, and the air supply assembly is connected to the outlet end of the vacuum pump.

[0018] The textile fabric enters the machine base frame through the fabric inlet hole, and passes through the dust removal mechanism and the spraying mechanism in sequence. When the vacuum suction pump is running, the textile fabric is dusted through the negative pressure dust collection box and the negative pressure adsorption box. The antibacterial agent solution enters the internal conduit through the diversion conduit, and is sprayed onto the textile fabric through the fixed conduit and the spraying protective cover. At the same time, the air supply component supplies gas to the spraying protective cover to improve the spraying rate of the antibacterial agent solution.

[0019] In one possible design, the dust removal mechanism further includes a connecting box, a connecting conduit, a connecting cylinder, and a curved conduit. The dust filter box is connected to the connecting box via a load-bearing branch pipe. The connecting box is connected to the connecting cylinder via the connecting conduit. The curved conduit is rotatably connected to both sides of the connecting cylinder. The curved conduit is connected to the negative pressure dust collection box via a load-bearing branch pipe. The negative pressure adsorption box is connected to the connecting box via a suction conduit.

[0020] In one possible design, the top of the negative pressure adsorption box is provided with the support mesh plate, and the textile fabric passes over the support mesh plate. When the vacuum pump is running, negative pressure is generated in the negative pressure adsorption box, so that the textile fabric adheres to the support mesh plate to form a stable support.

[0021] In one possible design, a mounting bracket is fixedly installed inside the base frame, and a scraper is provided on the mounting bracket. The bottom of the scraper contacts the textile fabric and is used to scrape off tightly adhered dust or impurities when the textile fabric moves.

[0022] In one possible design, the air supply assembly of the spraying mechanism includes a distribution cylinder, a dust filter housing, a gas delivery pipe, and a gas discharge pipe. The gas discharge pipe is connected to the outlet of the vacuum pump and the inlet of the dust filter housing. The gas delivery pipe is connected to the outlet of the dust filter housing and the distribution cylinder. The distribution cylinder is connected to multiple external conduits. The gas drawn out by the vacuum pump is filtered by the dust filter housing and then dispersed to the external conduits through the distribution cylinder.

[0023] In one possible design, the internal conduit is fixedly installed inside the external conduit. The bottom of the internal conduit is provided with multiple fixed conduits. The bottom end of the fixed conduit is provided with the spray protective cover. The top of the spray protective cover is provided with a gas supply pipe. The gas supply pipe is connected to the external conduit. Gas enters the spray protective cover through the gas supply pipe to increase the flow rate of the antibacterial agent solution.

[0024] In one possible design, a drive motor is fixedly mounted on one side of the base frame, and a positioning clamping plate is fixedly mounted on the output shaft of the drive motor. An electric push rod is fixedly mounted on the other side of the base frame, and a movable clamping plate is rotatably connected to the output shaft of the electric push rod. The positioning clamping plate and the movable clamping plate are used to clamp the roll of the textile fabric to achieve continuous winding.

[0025] In one possible design, the load-bearing branch pipe is connected to the negative pressure dust collection box via a matching pipe assembly. One end of each of the two load-bearing branch pipes is fixedly connected to a traction rod, which is placed on top of the base frame to adjust the position of the negative pressure dust collection box.

[0026] In this application, firstly, the textile fabric is placed into a printing and dyeing machine for printing. Then, an antibacterial agent solution, composed of plant extracts, minerals, and chitin / chitosan, is prepared and placed in a conveying mechanism. This conveying mechanism is connected to a spraying device to supply the antibacterial agent solution. The textile fabric is then conveyed from the fabric inlet hole on the machine frame into the machine frame, passing over the support mesh plate at the top of the negative pressure adsorption box. At this point, a vacuum pump is activated, generating suction within the negative pressure adsorption box to draw in dust from the bottom of the textile fabric, simultaneously ensuring the textile fabric adheres tightly to the support mesh. A stable support is formed on the plate. Then, the two negative pressure dust collection boxes are rotated to a horizontal position corresponding to the textile fabric. Under the suction force generated by the vacuum pump, the dust adhering to the textile fabric is attracted to the dust collection boxes for centralized filtration through the dust filter box, load-bearing branch pipe, connecting box, connecting conduit, connecting cylinder, two curved conduits, two load-bearing branch pipes, and two negative pressure dust collection boxes. This achieves dust removal and collection, keeping the textile fabric clean. During the movement of the textile fabric, the scraper on the mounting bracket scrapes the textile fabric, removing the dust tightly adhering to it. If impurities are scraped off, the textile fabric passes under the spraying box. The adapter conduit is connected to the conveying mechanism for the antibacterial agent solution, which is then delivered to the distribution conduit, dispersed into the internal conduit, and then through multiple fixed conduits to the corresponding spraying protective hood. The spraying protective hood disperses and sprays the antibacterial agent solution onto the textile fabric. Simultaneously, the gas drawn out by the vacuum pump is delivered through the gas exhaust pipe to the dust filter box for secondary filtration. The filtered gas is then delivered through the gas delivery pipe to the distribution cylinder, and then dispersed into multiple external conduits, and finally transported through multiple gas supply pipes. Inside the spray protective cover, the flow rate and spraying speed of the antibacterial agent solution are increased. When spraying the antibacterial agent solution onto the textile fabric, excess antibacterial agent solution is collected using a recycling container to prevent it from spilling. Finally, the roll of textile fabric is placed between the positioning clamping plate and the moving clamping plate. The electric push rod is activated to move the moving clamping plate closer to the roll, and the roll is clamped with the cooperation of the positioning clamping plate. The sprayed textile fabric is then fixed on the roll. The drive motor is activated to rotate the roll and rewind the textile fabric, achieving continuous spraying of the antibacterial agent solution.

[0027] Beneficial Effects: This invention solves the problem of fabric stability during dust removal by combining a negative pressure adsorption box with a supporting mesh plate. When the vacuum pump is running, the negative pressure not only removes dust from the bottom surface but also generates a strong vertical "adsorption anchoring force," tightly and smoothly adsorbing the textile fabric onto the surface of the supporting mesh plate. This design eliminates fabric shaking and wrinkling under strong airflow, ensuring the fabric receives double-sided dust removal and subsequent spraying in an absolutely flat state, significantly improving processing accuracy.

[0028] This invention establishes a dust removal mechanism combining mechanical scraping and negative pressure removal. By using a scraper on a mounting bracket to maintain contact with the moving fabric, tightly adhered paste spots or electrostatic dust are physically scraped off, disrupting the "anchoring" state of the impurities. Subsequently, the impurities are sucked away by a negative pressure dust collection box and an adsorption box that operate in both directions, thus solving the technical problem that single airflow dust removal cannot remove stubborn impurities.

[0029] This invention achieves closed-loop coupling utilization of pneumatic energy. High-speed exhaust gas discharged from the vacuum pump is purified by a dust filter and then reused as the power source for the spraying mechanism. This design breaks down the energy isolation between dust removal and spraying, eliminating the need for an additional spraying air pump. It improves the spray velocity and atomization effect of the antibacterial agent solution while significantly reducing overall energy consumption and equipment footprint.

[0030] This invention solves the problem of dust and impurities affecting fabrics by using negative pressure adsorption and dust collection box; it improves the uniformity and rate of spraying by using multiple conduits and gas assistance; it also sets up a recovery container to collect residual liquid and avoid spillage; finally, it can stably roll up the fabric to achieve continuous spraying operation, effectively improving the production quality and efficiency of natural antibacterial fabrics.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] In one embodiment: Refer to Figure 1-7 A production process for a natural antibacterial functional fabric includes the following steps:

[0043] S1. Place the textile fabric into the printing and dyeing machine and print the textile fabric.

[0044] S2. Prepare the antibacterial agent. Place the prepared antibacterial agent solution into the conveying mechanism and connect the conveying mechanism to the spraying equipment to supply the antibacterial agent solution to the spraying equipment.

[0045] S3. The textile fabric is fed into the spraying equipment. First, the textile fabric is dusted, and then an antibacterial agent solution is sprayed onto the textile fabric.

[0046] S4. After spraying the antibacterial agent solution onto the textile fabric, the textile fabric is rolled up.

[0047] Antibacterial agents are composed of a mixture of plant extracts, minerals, and chitin / chitosan.

[0048] like Figure 2-7 As shown, a production apparatus includes a spraying device, which includes a base frame 1. A fabric inlet hole 2 is formed on one inner wall of the base frame 1, through which textile fabric enters the base frame 1. A support base plate 15 is fixedly mounted on the base frame 1.

[0049] like Figure 2-7 As shown, the dust removal mechanism consists of the following: A vacuum pump 21 is fixedly installed on the top of the support base plate 15. A dust filter box 20 is fixedly installed at the suction end of the vacuum pump 21. A load-bearing branch pipe 19 is fixedly installed on one side of the dust filter box 20. The top end of the load-bearing branch pipe 19 extends to one side of the base frame 1 and is fixedly installed with a connecting box 17. A connecting conduit 16 is fixedly installed on the inner wall of the top of the connecting box 17. The top end of the connecting conduit 16 extends above the connecting box 17 and is fixedly connected to a connecting cylinder 5. The connecting cylinder 5 is fixedly installed on one side of the base frame 1. A rotatable curved conduit 6 passes through both inner walls of the connecting cylinder 5. The top end of the curved conduit 6 extends above the base frame 1 and is fixedly installed with a load-bearing branch pipe 7. Multiple mounting pipes 8 are fixedly installed at equal intervals on the inner wall of the bottom of the load-bearing branch pipe 7. The bottom ends of the multiple mounting pipes 8 extend below the load-bearing branch pipe 7 and are fixedly installed with the same negative pressure dust collection box 9. The same traction rod 14 is fixedly installed at one end of the two load-bearing branch pipes 7. The traction rod 14 is supported on the top of the base frame 1. Meanwhile, a negative pressure adsorption box 3 is fixedly installed inside the base frame 1. The negative pressure adsorption box 3 is located below the fabric inlet hole 2. A support mesh plate 4 is fixedly installed at the top opening of the negative pressure adsorption box 3. Multiple suction tubes 18 are fixedly installed at equal intervals on one side of the inner wall of the negative pressure adsorption box 3. One end of each suction tube 18 extends into the connecting box 17 and is fixedly connected to the inner wall of one side of the connecting box 17. Two mounting brackets 10 are also fixedly installed inside the base frame 1. The two mounting brackets 10 are staggered with the two negative pressure dust collection boxes 9. Scraper plates 11 are inserted on the mounting brackets 10. The bottom of the scraper plate 11 contacts the textile fabric. L-shaped fastening plates 12 are fixedly installed at equal intervals on the top of one side of the scraper plate 11. One side of the L-shaped fastening plate 12 is located on one side of the mounting bracket 10. The L-shaped fastening plate 12 is fixedly connected to the mounting bracket 10 by positioning fastening bolts 13.

[0050] During operation, the textile fabric is conveyed through the fabric inlet hole 2 into the machine base frame 1, allowing the fabric to pass over the support mesh plate 4. The two negative pressure dust collection boxes 9 are rotated to a horizontal position so that they correspond to the textile fabric. When the vacuum pump 21 is activated, suction is generated, which has two core functions: first, the dust is powerfully removed from the upper and lower surfaces through components such as the dust filter box 20; second, the negative pressure adsorption box 3 generates adsorption force through the mesh plate openings, like a "vacuum suction cup" to smoothly adsorb the moving fabric onto the supporting mesh plate 4, forcibly smoothing the fabric wrinkles and preventing shaking. Under the suction effect of the dust filter box 20, the load-bearing branch pipe 19, the connecting box 17, the connecting conduit 16, the connecting cylinder 5, the two curved conduits 6, the two load-bearing branch pipes 7, and the two negative pressure dust collection boxes 9, the negative pressure collection box 9 attracts the dust attached to the top of the textile fabric. At the same time, the negative pressure adsorption box 3 has an attractive force to attract the dust at the bottom of the textile fabric, and can also make the textile fabric adhere tightly to the supporting mesh plate 4 to form a stable support. Dust is conveyed into the dust filter box 20 for centralized filtration. During the dust removal process, the scraper 11 scrapes the textile fabric as it moves, removing the dust or impurities that are tightly adhered to the textile fabric, ensuring that the textile fabric remains clean before the antibacterial agent solution is sprayed on it.

[0051] This application can be used in the field of textile machinery technology, or in other fields applicable to this application.

[0052] In another embodiment: Reference Figure 3 , Figure 8 and Figure 9Based on the above embodiments, an improvement is made to the following: A production device, applied in the field of textile machinery technology, includes a spraying mechanism: A spraying operation box 22 is fixedly installed on a base frame 1.

The bottom of the air supply assembly is installed on the top of a support base plate 15, and the air supply assembly is connected to the outlet end of a vacuum pump 21. Multiple fixed conduits 31 are fixedly installed at equal intervals on the bottom inner wall of the internal conduit 25. The bottom ends of the fixed conduits 31 penetrate the bottom inner wall of the external conduit 23 and extend into the spraying operation box 22. A spraying protective cover 32 is fixedly installed at the bottom end of the fixed conduits 31. Two gas supply pipes 33 are symmetrically fixedly installed on the top inner wall of the spraying protective cover 32. The top ends of the two gas supply pipes 33 extend into the external conduit 23 and are fixedly connected to the bottom inner wall of the external conduit 23.

[0053] During operation, the textile fabric passes under the spraying chamber 22. The adapter conduit 26 is connected to the conveying mechanism for the antibacterial agent solution. The antibacterial agent solution is conveyed into the diversion conduit 24, dispersed into the internal conduit 25, and then dispersed into the corresponding spraying protective cover 32 through multiple fixed conduits 31. The spraying protective cover 32 then sprays the antibacterial agent solution onto the textile fabric. Simultaneously, when the vacuum pump 21 is running, the extracted gas is conveyed through the gas discharge pipe 29 to the dust filter box 30 for secondary filtration. The filtered gas is then conveyed through the gas delivery pipe 28 to the diversion cylinder 27, and then dispersed into multiple external conduits 23. After passing through multiple gas supply pipes 33, the gas is conveyed into the spraying protective cover 32, which inflates the spraying protective cover 32, increasing the flow rate of the antibacterial agent solution and improving the rate at which the antibacterial agent solution is sprayed onto the textile fabric.

[0054] like Figure 2-4As shown, a drive motor 36 is fixedly installed on one side of the base frame 1. The output shaft of the drive motor 36 extends into the base frame 1 and is fixedly installed with a positioning clamping plate 37. An electric push rod 38 is fixedly installed on the other side of the base frame 1. The output shaft of the electric push rod 38 extends into the base frame 1 and is rotatably connected to a movable clamping plate 39. The roll of the textile fabric is placed between the positioning clamping plate 37 and the movable clamping plate 39. The electric push rod 38 is activated to drive the movable clamping plate 39 closer to the roll, clamping the roll with the cooperation of the positioning clamping plate 37. The coated textile fabric is fixed on the roll, and the drive motor 36 is activated to drive the roll to rotate, winding up the textile fabric to achieve continuous spraying of the antibacterial agent solution.

[0055] A recycling container 34 is also fixedly installed on the base frame 1, located below the spraying operation box 22. A drain pipe 35 is fixedly installed on the bottom inner wall of one side of the recycling container 34, and one side of the drain pipe 35 extends to the outside of the base frame 1. When spraying antibacterial agent solution onto textile fabrics, the recycling container 34 is used to collect excess antibacterial agent solution to prevent the antibacterial agent solution from spilling everywhere.
