Description

Technical Field

[0001] The invention belongs to the field of textile fabrics, in particular to a highly waterproof and wear-resistant nylon plastic cloth and a production device thereof. Background Art

[0002] Nylon is a chemical fiber with a relatively strong structure. It is widely used in textiles, automobiles, mechanical parts and papermaking machinery. For example, nylon can be used to make clothing, shoes and socks, parasols, conveyor belts and packaging bags.

[0003] A Chinese patent with publication number CN111944441A discloses a waterproof nylon cloth and its manufacturing process, including a first core layer, a waterproof layer is hot-pressed and compounded on its upper end surface, a second core layer is fused and fixed to its lower end surface through a welding layer, a structural layer is fused and fixed to the lower end surface of the second core layer, an antibacterial layer is hot-pressed and compounded on the lower end surface of the structural layer, the first core layer and the second core layer are composed of polyamide-66, and the thickness is 8-10um, the structural layer is TPU polymer alloy, the waterproof nylon cloth has excellent waterproof performance, and the cloth strength is much higher than the market average level, and the cloth has good heat dissipation performance and antibacterial properties when used for civilian purposes.

[0004] There are still some problems in the above-mentioned waterproof nylon cloth manufacturing process. In the production of nylon plastic cloth, a water jet loom is used for cloth weaving. Since the water jet loom guides the weft yarn by spraying water columns, so that the weft yarn passes through the textile shed, the friction of the weft insertion work is small, and it is an energy-saving and environmentally friendly equipment. Its specific working process is: when the water jet loom is running, the rotation of the water pump cam causes the pump cam rod to pull the plunger to move, so that the water pump absorbs water from the float box, and the water is sprayed out from the nozzle after being pressurized; at the same time, the yarn presser is turned on to release the weft yarn, and the water flows in the water. Under the action, it is led from one side of the fabric to the other side; after the weft insertion is completed, the yarn presser is closed to clamp the weft yarn until the next weft insertion; after the nylon plastic cloth is produced by the water jet loom, some moisture that is difficult to remove will remain in the cloth. If this moisture is not dried, it is easy to cause the cloth to mold and reduce the quality of the finished nylon plastic cloth. In the traditional drying device, only air heating is performed without air flow, the drying effect is limited, and the structure is complicated and the use cost is high. The above-mentioned waterproof nylon cloth manufacturing process does not effectively solve these problems.

[0005] To this end, the present invention provides a highly waterproof and wear-resistant nylon plastic sheet and a production device thereof. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the highly waterproof and wear-resistant nylon plastic cloth of the present invention comprises a cloth base, a water-proof layer is hot-pressed and compounded on the upper end surface of the cloth base, and a primer layer and a surface coating are coated on the top of the water-proof layer;

[0008] The cloth base is a polyamide plastic cloth;

[0009] The waterproof layer is a PTFE polytetrafluoroethylene film layer;

[0010] The base coating is a liquid type polyurethane resin coating, and the coating amount is 22-24g / m 2 , the curing temperature is 100-105℃; after curing, the polyurethane resin forms a mesh film, which plays a role in improving the waterproof and anti-penetration performance of the nylon plastic cloth;

[0011] The surface coating is chlorosulfonated polyethylene coating, and the coating amount is 18-20g / m 2 , the curing temperature is 115-120℃; after curing, chlorosulfonated polyethylene forms an elastic coating, which increases the thickness and stiffness of the nylon plastic sheet, and at the same time improves the wear resistance of the nylon plastic sheet.

[0012] A highly waterproof and wear-resistant nylon plastic cloth production device, which is used to produce the highly waterproof and wear-resistant nylon plastic cloth described above, comprises a workbench, which is used in conjunction with a water jet loom for producing nylon plastic cloth, and is equipped with a transmission roller and a winding roller for winding the nylon plastic cloth, and a drying box is fixedly installed on the top of the workbench, and the drying box is located between the transmission roller and the winding roller, and the nylon plastic cloth passes through the drying box, and a heating box is installed at the bottom of the drying box.

After the temperature inside the heating chamber rises, the pressure becomes higher, and the hot air in the heating chamber enters the pressure storage chamber 1 and the pressure storage chamber 2 for storage. At the same time, the pressure in the pressure storage chamber 1 and the pressure storage chamber 2 also increases. After the pressure rises to a certain stage, the duct between the pressure storage chamber 1 and the pressure storage chamber 2 and the nozzle is opened, so that the hot air flow is quickly ejected outward through the nozzle to dry the nylon plastic sheet in the drying box. Compared with traditional drying devices, the fast-flowing hot air flow has a better drying effect on the nylon plastic sheet.

[0014] Preferably, a central rod is rotatably installed inside the heating box, and sealing plates that block the conduit are fixedly installed at the top and bottom ends of the outer side of the central rod, and through holes corresponding to the conduits are opened on the sealing plates, and the two through holes in the horizontal direction are staggered, and the two through holes in the vertical direction are staggered. When working, in the initial state, the upper and lower sealing plates respectively block the conduit between the pressure storage chamber 1 and the nozzle, and the conduit between the pressure storage chamber 2 and the heating chamber, and the pressure storage chamber 1 and the heating chamber, and the pressure storage chamber 2 and the nozzle are connected through the through holes. At this time, the high-pressure hot air flow in the pressure storage chamber 2 is ejected outward through the nozzle, and at the same time, the heating chamber transports hot air flow to the pressure storage chamber 1;

[0015] When the hot air flow in the pressure storage chamber two is almost finished, rotate the center rod to open the duct between the pressure storage chamber one and the nozzle and the duct between the pressure storage chamber two and the heating chamber, and block the ducts between the pressure storage chamber one and the heating chamber, as well as between the pressure storage chamber two and the nozzle. Then, the hot air flow in the pressure storage chamber one is switched to be ejected, and the heating chamber replenishes the hot air flow to the pressure storage chamber two. In this way, continuous hot air flow can be ejected from the drying box, which improves the problem of undried areas of nylon plastic cloth caused by ejection interruption due to the hot air flow replenishment process. The drying is more comprehensive and reliable to use.

During operation, in the process of transmitting the nylon plastic sheet, the transmission roller rotates continuously, and the incomplete gears are rotated through the bevel gear assembly, and the incomplete gears drive the driven gears and the center rod to rotate intermittently. After the center rod rotates, the switching of the injection hot air flow and the supplementary hot air flow of the pressure storage chamber 1 and the pressure storage chamber 2 is realized, and there is an interval in the rotation of the center rod, which provides time for the supplementary hot air flow of the pressure storage chamber 1 and the pressure storage chamber 2, so that the required high-pressure hot air flow can be formed in the pressure storage chamber 1 and the pressure storage chamber 2, and there is no need to set up an additional electric drive mechanism for the center rod, which reduces the use cost, has a simple structure, and is easy to use.

A turntable is rotatably installed below the top seat, and the turntable and the piston are movably connected through a connecting rod. The installation position of the connecting rod and the turntable is located at the eccentric position of the turntable. When working, the nozzle sprays hot air upward to dry the nylon plastic sheet, and generates air with high humidity at the top of the drying box. The turntable is started to rotate, and the turntable drives the piston to reciprocate in the ventilation groove through the connecting rod, and the moisture in the drying box is sucked out, so that the drying box remains dry, thereby improving the drying effect of the drying box on the nylon plastic sheet.

[0018] Preferably, the exhaust hole and the air extraction hole are both movably connected with sealing rods, the two sealing rods block the exhaust hole and the air extraction hole respectively, a return spring is installed on the sealing rod, a dial plate and two connecting pieces are rotatably installed on the top of the top seat, the connecting piece is movably connected to the sealing rod, and a convex plate for dialing the connecting piece is arranged on the dial plate.

[0038] Embodiment 1

[0039] like Figure 2As shown, a highly waterproof and wear-resistant nylon plastic cloth production device is used to produce the highly waterproof and wear-resistant nylon plastic cloth described above, comprising a workbench 1, the workbench 1 is used in conjunction with a water jet loom for producing nylon plastic cloth, a transmission roller 7 and a winding roller 10 for winding the nylon plastic cloth are installed on the workbench 1, a drying box 8 is fixedly installed on the top of the workbench 1, the drying box 8 is located between the transmission roller 7 and the winding roller 10, the nylon plastic cloth passes through the drying box 8, and a heating box 9 is installed at the bottom of the drying box 8. During operation, after the nylon plastic cloth is processed by the water jet loom, when the nylon plastic cloth is wound, the transmission roller 7 and the winding roller 10 are started to rotate, the heating box 9 heats the drying box 8, and the temperature in the drying box 8 is increased, the nylon plastic cloth moves to the drying box 8 via the transmission roller 7, and the moisture on the nylon plastic cloth is dried by the drying box 8, so that the nylon plastic cloth remains dry, which improves the problem that the nylon plastic cloth is moist, easily mildewed, and reduces the quality of the finished product.

[0040] like Figures 2 to 3 As shown, the interior of the heating box 9 is provided with a heating chamber 11, a pressure storage chamber 1 13 and a pressure storage chamber 2 14, the interior of the heating chamber 11 is provided with a heating unit 12, the interior of the drying box 8 is provided with a nozzle 15, and the nozzle 15 is located below the nylon plastic cloth. The pressure storage chamber 1 13 is connected with the heating chamber 11 and the nozzle 15, and the pressure storage chamber 2 14 is connected with the heating chamber 11 and the nozzle 15 through a conduit 16. The interior of the heating box 9 and the outer sides of the heating chamber 11, the pressure storage chamber 1 13 and the pressure storage chamber 2 14 are provided with a heat insulation layer, the side wall of the heating chamber 11 is provided with an air inlet, and a one-way air valve 17 is installed in the conduit 16 and the air inlet. During operation, the heating unit 12 can adopt an electric heating plate structure, which generates heat after being energized. The air in the heating chamber 11 is heated by the heating unit 12. After the temperature inside the heating chamber 11 rises, the pressure becomes higher, and the hot air in the heating chamber 11 enters the pressure storage chamber 13 and the pressure storage chamber 2 14 for storage. At the same time, the pressure in the pressure storage chamber 13 and the pressure storage chamber 2 14 also increases. After the pressure increases to a certain stage, the duct 16 between the pressure storage chamber 13 and the pressure storage chamber 2 14 and the nozzle 15 is opened, so that the hot air flow is quickly ejected outward through the nozzle 15 to dry the nylon plastic sheet in the drying box 8. Compared with traditional drying devices, the fast-flowing hot air flow has a better drying effect on the nylon plastic sheet.

[0041] like Figures 2 to 4As shown, a central rod 18 is rotatably installed inside the heating box 9, and sealing plates 19 that block the conduit 16 are fixedly installed at the top and bottom ends of the outer side of the central rod 18. A through hole 20 corresponding to the conduit 16 is opened on the sealing plate 19, and the two through holes 20 in the horizontal direction are staggered, and the two through holes 20 in the vertical direction are staggered. When working, in the initial state, the upper and lower sealing plates 19 respectively block the conduit 16 between the pressure storage chamber 13 and the nozzle 15, and the conduit 16 between the pressure storage chamber 2 14 and the heating chamber 11. The pressure storage chamber 13 and the heating chamber 11, and the pressure storage chamber 2 14 and the nozzle 15 are connected through the through holes 20. At this time, the high-pressure hot air flow in the pressure storage chamber 2 14 is ejected outward through the nozzle 15, and at the same time, the heating chamber 11 transports hot air flow to the pressure storage chamber 13;

[0042] When the hot air flow in the pressure storage chamber 14 is almost finished, rotate the center rod 18 to open the duct 16 between the pressure storage chamber 13 and the nozzle 15 and the duct 16 between the pressure storage chamber 14 and the heating chamber 11, and block the ducts 16 between the pressure storage chamber 13 and the heating chamber 11, and between the pressure storage chamber 14 and the nozzle 15. Then, the hot air flow in the pressure storage chamber 13 is switched to be ejected, and the heating chamber 11 supplements the hot air flow to the pressure storage chamber 14. In this way, continuous hot air flow can be ejected from the drying box 8, which improves the problem of undried areas of the nylon plastic sheet caused by ejection interruption due to the hot air flow replenishment process. The drying is more comprehensive and reliable to use.

[0043] like Figures 2 to 5 As shown, the workbench 1 is movably provided with an incomplete gear 21 and a driven gear 22 meshing with each other, the driven gear 22 is connected to the center rod 18 through a chain belt 23, and the incomplete gear 21 is connected to the transmission roller 7 through a bevel gear assembly 24. During operation, in the process of transmitting the nylon plastic sheet, the transmission roller 7 rotates continuously, and rotates with the incomplete gear 21 through the bevel gear assembly 24, and the incomplete gear 21 drives the driven gear 22 and the center rod 18 to rotate intermittently. After the center rod 18 rotates, the switching of the injection hot air flow and the supplementary hot air flow of the pressure storage chamber 1 13 and the pressure storage chamber 2 14 is realized, and there is an interval in the rotation of the center rod 18, which provides time for the supplementary hot air flow of the pressure storage chamber 1 13 and the pressure storage chamber 2 14, so that the required high-pressure hot air flow can be formed in the pressure storage chamber 1 13 and the pressure storage chamber 2 14, and there is no need to set up an additional electric drive mechanism of the center rod 18, which reduces the use cost, has a simple structure, and is easy to use.

[0044] Embodiment 2

[0045] like Figures 2 to 6As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a top seat 25 is fixedly mounted on the workbench 1, and an exhaust hole and an air extraction hole are respectively arranged on the left and right sides of the top seat 25, and the air extraction hole is connected to the drying box 8. A ventilation groove is provided at the bottom of the top seat 25, and a piston 26 is movably mounted in the ventilation groove, and the exhaust hole and the air extraction hole are evenly connected to the ventilation groove. A turntable 27 is rotatably mounted below the top seat 25, and the turntable 27 and the piston 26 are movably connected through a connecting rod 28, and the mounting position of the connecting rod 28 and the turntable 27 is located at the eccentric position of the turntable 27. During operation, the nozzle 15 sprays hot air upward, and after drying the nylon plastic sheet, air with high humidity is generated at the top of the drying box 8, and the turntable 27 is started to rotate, and the turntable 27 drives the piston 26 to do reciprocating motion in the ventilation groove through the connecting rod 28, and the moisture in the drying box 8 is sucked out, so that the drying box 8 is kept dry, thereby improving the drying effect of the drying box 8 on the nylon plastic sheet.

[0046] like Figures 2 to 6 As shown, sealing rods 29 are movably inserted in the exhaust hole and the exhaust hole, and the two sealing rods 29 respectively block the exhaust hole and the exhaust hole. A return spring is installed on the sealing rod 29. A dial plate 30 and a connecting member 31 are rotatably installed on the top of the top seat 25. The connecting member 31 is movably connected to the sealing rod 29, and a convex plate for driving the connecting member 31 is provided on the dial plate 30. During operation, the start plate 30 is started to rotate back and forth. When the plate 30 rotates and contacts the sealing rod 29, the sealing rod 29 will be moved. The sealing rod 29 moves back and forth under the action of the plate 30 and the return spring. The movement of the sealing rod 29 and the piston 26 is designed. When the sealing rod 29 in the air extraction hole moves down, the air extraction hole is opened, and the piston 26 moves down, the moisture in the drying box 8 can be smoothly sucked into the ventilation groove; then the sealing rod 29 in the air extraction hole moves up and resets, the sealing rod 29 in the exhaust hole moves down, and the piston 26 moves upward to discharge the moisture in the ventilation groove through the exhaust hole, thereby realizing the function of stably discharging the moisture in the drying box 8 in one direction, improving the problem that the moisture may move back to the inside of the drying box 8, and improving the moisture discharge effect.

[0047] like Figures 2 to 8As shown, the top seat 25 is internally rotatably installed with a main gear 32 and a sub-gear 33 that mesh with each other, and a steering wheel 34 is fixedly installed on the back of the dial plate 30. The main gear 32 and the sub-gear 33 are staggered front and back from the steering wheel 34. The main gear 32 and the sub-gear 33 are both provided with a round rod group 35 for shifting the steering wheel 34, and the two round rod groups 35 are staggered. The ring side of the steering wheel 34 is provided with a concave hole corresponding to the round rod group 35. The turntable 27 and the main gear 32 are both connected to the transmission roller 7 through a chain assembly 36. During operation, when the transmission roller 7 rotates, the chain assembly 36 drives the turntable 27 and the main gear 32 to rotate. After the turntable 27 rotates, it drives the piston 26 to reciprocate to discharge moisture. After the main gear 32 rotates, it drives the sub-gear 33 to rotate in the opposite direction. The main gear 32 and the sub-gear 33 drive the steering plate 34 and the dial plate 30 to rotate back and forth through the round rod group 35. The back-and-forth rotating dial plate 30 drives the two sealing rods 29 to move alternately. The device drives the piston 26 and the sealing rod 29 to automatically discharge moisture through the transmission roller 7, and there is no need to set up an additional electric drive mechanism for the piston 26 and the sealing rod 29, which reduces the use cost, has a simple structure, and is easy to use.

[0048] Working principle:

[0049] After the nylon plastic sheet is processed by the water jet loom, when the nylon plastic sheet is rolled up, the transmission roller 7 and the winding roller 10 are started to rotate, the heating box 9 heats the drying box 8 to increase the temperature in the drying box 8, and the nylon plastic sheet is moved to the drying box 8 via the transmission roller 7. The moisture on the nylon plastic sheet is dried by the drying box 8, so that the nylon plastic sheet is kept dry, thereby improving the problem that the nylon plastic sheet carries moisture, is prone to mildew, and reduces the quality of the finished product.

[0050] The heating unit 12 can adopt an electric heating plate structure, which generates heat after being powered on. The air in the heating chamber 11 is heated by the heating unit 12. After the temperature inside the heating chamber 11 rises, the pressure becomes higher, and the hot air in the heating chamber 11 enters the pressure storage chamber 1 13 and the pressure storage chamber 2 14 for storage. At the same time, the pressure in the pressure storage chamber 1 13 and the pressure storage chamber 2 14 also increases. After the pressure increases to a certain stage, the duct 16 between the pressure storage chamber 1 13 and the pressure storage chamber 2 14 and the nozzle 15 is opened, so that the hot air flow is quickly ejected outward through the nozzle 15 to dry the nylon plastic sheet in the drying box 8. Compared with traditional drying devices, the fast-flowing hot air flow has a better drying effect on the nylon plastic sheet.

[0051] In the initial state, the upper and lower sealing plates 19 respectively block the conduit 16 between the pressure storage chamber 13 and the nozzle 15, and the conduit 16 between the pressure storage chamber 14 and the heating chamber 11. The pressure storage chamber 13 and the heating chamber 11, and the pressure storage chamber 14 and the nozzle 15 are connected through the through hole 20. At this time, the high-pressure hot air flow in the pressure storage chamber 14 is ejected outward through the nozzle 15, and at the same time, the heating chamber 11 transports the hot air flow to the pressure storage chamber 13.

[0052] When the hot air flow in the pressure storage chamber 14 is almost finished, rotate the center rod 18 to open the duct 16 between the pressure storage chamber 13 and the nozzle 15 and the duct 16 between the pressure storage chamber 14 and the heating chamber 11, and block the ducts 16 between the pressure storage chamber 13 and the heating chamber 11, and between the pressure storage chamber 14 and the nozzle 15. Then, the hot air flow in the pressure storage chamber 13 is switched to be ejected, and the heating chamber 11 supplements the hot air flow to the pressure storage chamber 14. In this way, continuous hot air flow can be ejected from the drying box 8, which improves the problem of undried areas of the nylon plastic sheet caused by ejection interruption due to the hot air flow replenishment process. The drying is more comprehensive and reliable to use.

[0053] During the transmission of the nylon plastic sheet, the transmission roller 7 rotates continuously and rotates with the incomplete gear 21 through the bevel gear assembly 24. The incomplete gear 21 drives the driven gear 22 and the center rod 18 to rotate intermittently. After the center rod 18 rotates, the switching of the jet hot air flow and the supplementary hot air flow of the pressure storage chamber 13 and the pressure storage chamber 2 14 is realized. There is an interval in the rotation of the center rod 18, which provides time for the hot air flow supplemented by the pressure storage chamber 13 and the pressure storage chamber 2 14, so that the required high-pressure hot air flow can be formed in the pressure storage chamber 13 and the pressure storage chamber 2 14. There is no need to set up an additional electric drive mechanism for the center rod 18, which reduces the use cost, has a simple structure, and is easy to use.

[0054] The nozzle 15 sprays hot air upward to dry the nylon plastic sheet, and then generates air with high humidity at the top of the drying box 8. The turntable 27 is started to rotate, and the turntable 27 drives the piston 26 to reciprocate in the ventilation groove through the connecting rod 28, so that the moisture in the drying box 8 is sucked out, so that the drying box 8 remains dry, thereby improving the drying effect of the drying box 8 on the nylon plastic sheet.

[0055] The start plate 30 is rotated back and forth. When the plate 30 rotates and contacts the sealing rod 29, the sealing rod 29 will be moved. The sealing rod 29 moves back and forth under the action of the plate 30 and the return spring. The movement of the sealing rod 29 and the piston 26 is designed. When the sealing rod 29 in the air extraction hole moves down, the air extraction hole is opened, and the piston 26 moves down, the moisture in the drying box 8 can be smoothly sucked into the ventilation groove; then the sealing rod 29 in the air extraction hole moves up and resets, the sealing rod 29 in the exhaust hole moves down, and the piston 26 moves upward to discharge the moisture in the ventilation groove through the exhaust hole, thereby realizing the function of stably discharging the moisture in the drying box 8 in one direction, improving the problem that the moisture may move back to the inside of the drying box 8, and improving the moisture discharge effect.

[0056] When the transmission roller 7 rotates, the chain assembly 36 drives the turntable 27 and the main gear 32 to rotate. After the turntable 27 rotates, it drives the piston 26 to reciprocate to discharge moisture. After the main gear 32 rotates, it drives the sub-gear 33 to rotate in the opposite direction. The main gear 32 and the sub-gear 33 drive the steering plate 34 and the dial plate 30 to rotate back and forth through the round rod group 35. The back-and-forth rotating dial plate 30 drives the two sealing rods 29 to move alternately. The device drives the piston 26 and the sealing rod 29 to automatically discharge moisture through the transmission roller 7, and there is no need to set up an additional electric drive mechanism for the piston 26 and the sealing rod 29, which reduces the use cost, has a simple structure, and is easy to use.
