Description

Technical Field

[0001] The invention relates to the field of carpets, in particular to a stain-resistant nylon carpet, a carpet manufacturing device and a carpet manufacturing method. Background Art

[0002] Nylon carpet is a new type of carpet woven with nylon fiber. Anti-fouling agent and dust-proof coating are added to the nylon fiber, which makes the nylon carpet have higher anti-fouling and dust-proof ability, making the carpet surface brighter and easier to clean.

[0003] Nylon carpets have the characteristics of good dust resistance, high strength, good wear resistance, and good elastic recovery. They are often used in hotel corridors, stairs, living rooms and other areas with large traffic. In places with large traffic, nylon carpets will inevitably get damp or come into contact with water. For example, on rainy days, umbrellas and shoes will be stained with rainwater, which will be brought to the nylon carpets and make them damp. However, nylon carpets have poor ventilation and air permeability, and are prone to produce odors, especially in humid environments. Due to the poor air permeability of nylon, once it encounters water, it is difficult for the water to evaporate. Long-term moisture or water contact will cause the nylon carpets to be dissolved, resulting in bulging and deformation, which will affect the service life of the carpets. Summary of the invention

[0006] When the support part absorbs water, the upper end surface of the support part absorbs water and expands, and the movable end of the support part moves downward to support the carpet, so that the carpet leaves the placement surface, thereby improving the ventilation effect.

[0007] Preferably, the bottom surface of the support portion is also provided with a fiber layer that swells when exposed to water, and the density and thickness of the material of the bottom surface are smaller than the density and thickness of the material of the upper end surface.

[0011] S2. Weave nylon thread into a surface layer, and apply an anti-loosening coating on the back of the surface layer;

[0012] S3. Backing production:

[0018] 7. A manufacturing device for stain-resistant nylon carpet, used in the bonding process of step S4, comprising a machine body, a frame fixedly mounted on the machine body, and a hydraulic rod fixedly mounted on the frame;

[0019] The machine body is provided with a transmission chain, on which two horizontally placed bearing plates are fixedly installed, and the transmission chain is used to carry different bearing plates into the frame, and the bearing plates are provided with support bars, on which the support parts are placed, and above the bearing plates, a pressing plate capable of sliding up and down is provided, and between the pressing plate and the bearing plates, a carpet is placed;

In addition, combined with through holes, the air permeability and ventilation effect of the nylon carpet are increased, which can accelerate the evaporation of water, accelerate the drying of the nylon carpet, and reduce the deformation of the nylon carpet.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in 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.

[0039] See also Figure 1-2 The present embodiment provides a stain-resistant nylon carpet, including a surface layer 1, which is made of nylon fiber (such as nylon) by weaving or tufting. The bottom of the surface layer 1 is coated with an anti-loosening coating. The anti-loosening coating uses vinyl chloride-vinylidene chloride copolymer emulsion as a base material, and is mixed with plasticizers, thickeners and fillers to form a water-soluble coating, which is applied to the back of the surface layer to increase the firmness of the surface layer fibers and prevent them from falling off easily.

[0040] A backing 2 is glued to the back of the surface layer 1, and a plurality of evenly distributed through holes 3 are opened on the backing 2, and the through holes 3 can improve the air permeability of the carpet. A U-shaped rubber strip 4 is glued to the bottom surface of the backing 2, and a supporting portion 5 of an arc-shaped sheet structure is glued inside the U-shaped rubber strip 4. The supporting portion 5 is made of tough or flexible material, one end of the supporting portion 5 is glued to the U-shaped rubber strip 4, and the other end is a movable end, and the movable end is also located inside the U-shaped rubber strip 4. In a normal state, the bottom of the movable end is just flush with the bottom opening of the U-shaped rubber strip 4, and the upper end surface of the supporting portion 5 is a wood fiber layer that swells when exposed to water.

[0041] Since one end of the support part 5 is a movable end, when a person's foot steps on the carpet, the movable end of the support part 5 is in a free state, and the surface layer 1 and the backing 2 can be compressed normally under the pressure of the human body without damaging the support part 5.

[0042] When water is sprinkled on the nylon carpet, the water will flow down along the through hole 3 to the bottom of the carpet, and the water will contact the support part 5. The support part 5 will absorb water, and since the upper end of the support part 5 is a wood fiber layer that swells when it encounters water, the wood fiber layer at the upper end of the support part 5 absorbs water and swells when it encounters water, so that the movable end of the support part 5 bends downward and supports the carpet upward, so that there is a gap between the carpet and the ground, and the gap can be used for air circulation to accelerate the evaporation of water, and can prevent the carpet from being soaked in water for a long time.

[0043] For this improvement, the applicant mainly targets small square nylon carpets, such as carpets with a size of 50cm*50cm, or carpets with a size of 25cm*25cm and carpets with a size of 25cm*100cm.

[0044] When the support portion 5 absorbs water and expands, Figure 3 As shown, the bending degree of the support portion 5 increases, that is, the free end of the support portion 5 is displaced and bent downward, and the carpet is supported upward away from the ground to form a gap. The block-shaped soaked carpet will be slightly higher than the surrounding dry carpet, and air can enter the gap from between the carpets, and air can also enter the through hole 3, allowing air to flow. However, the height of the soaked carpet is greater than that of other carpets, that is, the height of the through hole 3 is greater than the height of the gap between the carpets, and the gap between the carpets can be used to enter air, and the airflow flows upward from the through hole 3 (similar to the chimney effect), so that the gap forms a cycle, which can accelerate air evaporation. When the water evaporates, the support portion 5 will return to its original position, that is, the free end of the support portion 5 is located inside the U-shaped rubber strip 4.

[0045] like Figure 3 As shown, when the support part 5 absorbs water, the carpet is supported upward, but the support part 5 is still in a bent state. When a human body steps on the carpet, the weight of the human body is relatively large, and the free end of the support part 5 will enter the inside of the U-shaped rubber strip 4 under the pressure of the human body, and the support part 5 will not be damaged. When the pressure of the human body disappears, the free end of the support part 5 will extend downward from the inside of the U-shaped rubber strip 4 and continue to support the carpet, so that the carpet remains in the state of being suspended from the ground, which can accelerate air flow and is conducive to the evaporation of water and the drying of the carpet.

[0046] This technical solution is also suitable for large-area integral carpets. However, since the carpet is integral, the support portion 5 will only slightly separate the carpet from the ground after absorbing water. Moreover, since other parts of the integral carpet are still in contact with the laying surface, when the carpet is lifted up, the flowing air can only enter and be discharged from the through hole 3, which can still accelerate the evaporation of water.

[0047] In this embodiment, the bottom surface of the support portion 5 is also provided with a fiber layer that swells when exposed to water. The density and thickness of the material of the bottom surface are smaller than the density and thickness of the material of the upper end surface. After encountering water, the expansion and deformation degree of the bottom surface of the support portion 5 is smaller than that of the upper end surface. The support portion 5 can still deform downward and support the carpet.

[0048] It is worth mentioning that Figure 1 As shown, the bottom surface of the backing 2 is coated with one or more rubber layers, and the U-shaped rubber strip 4 is bonded to the rubber layer. Subsequently, multiple layers of rubber can be laid to wrap the outer side of the U-shaped rubber strip 4 so that multiple U-shaped rubber strips 4 are located on a flat surface, which can make the contact surface between the carpet and the laying surface basically remain on the same plane, thereby improving the comfort of walking.

[0049] In a further embodiment, a method for manufacturing a stain-resistant nylon carpet is also disclosed, comprising the following steps:

[0050] S1. Put the nylon yarn into a viscose bath, apply a layer of glue on the surface of the yarn, and perform spinning treatment on the yarn. The surface of the treated nylon yarn is coated with an oil-proof agent (such as a fluorine-free oil-proof agent and a carbon six water-proof agent, so that the nylon yarn has the function of being oil-proof or waterproof.

[0051] S2. The nylon thread is woven into a surface layer by an anti-loosening machine, and an anti-loosening coating is applied on the back of the surface layer;

[0052] S3. Backing production:

[0053] Using jute plain woven net or polypropylene woven fabric or non-woven fabric as primary backing, coating styrene-butadiene latex or natural latex or water-soluble rubber on the primary backing as adhesive coating, laminating jute cloth on the adhesive coating, and coating a rubber layer on the bottom surface of the backing 2;

[0054] S4. The U-shaped rubber strip 4 is glued to the rubber layer, and the rubber is laid between the U-shaped rubber strips 4, and the laid rubber is bonded to the outer side of the U-shaped rubber strip 4 and the rubber layer of the backing 2, until the laying of the rubber is the same height as the outer side of the U-shaped rubber strip 4, and the laying of the rubber is stopped, so that the U-shaped rubber strip 4 is located on a flat plane;

[0055] S5. The upper end surface of the support portion 5 is coated with glue and bonded to the top of the inner cavity of the U-shaped rubber strip 4, and then dried to produce a nylon carpet.

[0056] In the above method for producing nylon carpet, since it is necessary to bond more supporting parts 5 to the U-shaped rubber strip 4, the applicant has specially developed a device for bonding the supporting parts 5 in order to save labor costs, which is used to manufacture anti-fouling nylon carpet to improve production efficiency. The specific structure is as follows:

[0057] like Figure 4-6 As shown, it includes a body 6, which is a rectangular parallelepiped frame structure. A transmission chain 12 is rotatably installed on the upper cross bar of the body 6. A chassis is fixedly installed inside the frame of the body 6. A drive motor 14 is fixedly installed inside the chassis. A sprocket 13 is fixedly installed at the output end of the drive motor 14. The sprocket 13 is installed together with the transmission chain 12 to provide power to the transmission chain 12 and drive the transmission chain 12 to move horizontally on the body 6, as shown in FIG. Figure 6 A workbench 15 is also fixedly mounted on the upper end of the machine body 6.

[0058] A frame 7 is fixedly mounted at the middle of the upper end of the body 6. Figure 4 and Figure 5 As shown, the frame 7 is a rectangular parallelepiped structure with openings at the bottom and both ends. The frame 7 is located directly above the chassis, and the workbench 15 is located at the bottom opening of the frame 7.

[0059] Two horizontally placed bearing plates 11 are fixedly mounted on the transmission chain 12. Figure 5 and Figure 6 As shown, the two bearing plates 11 are located on the same horizontal plane. When the transmission chain 12 is working, it can carry one of the bearing plates 11 into the frame 7, while the other bearing plate 11 is located outside the frame 7, so that the support part 5 is conveniently placed on the external bearing plate 11.

[0060] A hydraulic rod 8 is fixedly installed on the upper end of the frame 7. The telescopic end of the hydraulic rod 8 is located inside the frame 7, and a load-bearing plate 17 is fixedly installed on the telescopic end of the hydraulic rod 8. When the hydraulic rod 8 is telescopic, it is used to move the load-bearing plate 17 up and down in the frame 7.

[0061] like Figure 7 As shown, guide posts 18 are fixedly installed at the four corners of the upper end surface of the carrier plate 11, and pressure plates 16 are slidably installed on the four guide posts 18. Figure 7 As shown, guide holes matching the guide posts are provided at the four corners of the pressing plate 16, and a spring 19 is installed on the outer side of the guide post 18. The spring 19 is used between the bearing plate 11 and the pressing plate 16 to provide an upward elastic force to the pressing plate 16. The pressing plate 16 is used to place a carpet, and the opening of the U-shaped rubber strip 4 of the carpet is placed downward.

[0062] A plurality of support strips 10 are fixedly mounted on the upper end surface of the carrier plate 11. The support strips 10 are provided with a plurality of evenly distributed placement grooves. The shape of the placement grooves matches the shape of the support portion 5. The support portion 5 can be directly placed in the placement grooves, and the upper end of the support portion 5 is just located outside the placement grooves. In this embodiment, the height of the support strips 10 is just the same as the opening depth of the U-shaped rubber strip 4, and the number of the support strips 10 is the same as the number of the U-shaped rubber strip 4, and the positions are directly opposite each other. When pressing, the support strips 10 can be inserted into the interior of the U-shaped rubber strip 4, and the inclined upper end of the support portion 5 just contacts the top of the inner cavity of the U-shaped rubber strip 4. At the same time, the outer side of the U-shaped rubber strip 4 and the bottom of the carpet just contact the carrier plate 11. When the support portion 5 and the U-shaped rubber strip 4 are pressed, the entire carpet can be pressed at the same time.

[0063] In this embodiment, a mounting plate is fixedly installed at the corner of the pressing plate 16, and a support shaft 161 is fixedly installed on the mounting plate. The support shaft 161 is located on the side of the pressing plate 16. Figure 8 As shown, a limit plate 162 is rotatably mounted on the support shaft 161, and a torsion spring is also installed between the limit plate 162 and the support shaft 161, and the torsion spring provides an inward torsion force to the limit plate 162. The end of the limit plate 162 away from the support shaft is set as a protruding structure, and the lower part of the side wall of the pressure plate 16 is provided with an inwardly inclined inclined surface structure. The bottom surface of the pressure plate 16 is used to place a carpet.

[0064] When the carpet is placed on the bottom surface of the pressing plate 16 , the side of the limiting plate 162 fits together with the inclined surface of the pressing plate 16 under the action of the torsion spring. At this time, the protruding structure is inclined upward to generate a squeezing force on the edge of the carpet to fix the carpet on the pressing plate 16 .

[0065] When performing the bonding operation, since there are two supporting plates 11, the two supporting plates 11 can alternately enter the interior of the frame 7 for bonding operation under the drive of the transmission chain 12, and there is always one supporting plate 11 located on the outside of the frame 7, so that the fabric on the supporting plate 11 and the pressing plate 16 can be continuously aligned.

[0066] When laying the carpet, first fix the carpet on the pressing plate 16 outside the frame 7, then place the supporting parts 5 one by one in the placement groove of the supporting strip 10. After the placement is completed, glue is applied to the sharp corners of the upper end of the supporting parts 5. The transmission chain 12 moves the external load-bearing plate 11 and the pressing plate 16 together into the frame 7, while the other load-bearing plate 11 and the pressing plate 16 move from the frame 7 to the outside. Then the hydraulic rod 8 can be made to work, and the load-bearing plate 17 fits the upper end of the pressing plate 16. As the hydraulic rod 8 is extended, the pressing plate 16 fits the carpet with the lower load-bearing plate 11, and at the same time, the supporting part 5 enters the U-shaped rubber strip 4 and is bonded to the top of the inner cavity of the U-shaped rubber strip 4. After maintaining the pressure for 5-10 minutes, the hydraulic rod 8 contracts, the load-bearing plate 17 moves upward, and the pressing plate 16 is separated from the load-bearing plate 11 under the action of the spring 19, thereby completing the bonding of the supporting part 5 and the pressing of the carpet. The hydraulic rod 8 is retracted to the shortest, the load-bearing plate 17 is separated from the pressing plate 16, and the transmission chain 12 can move the load-bearing plate 11 and the pressing plate 16 in the frame 7 to the outside, remove the carpet and continue to discharge the material, while the other load-bearing plate 11 and the pressing plate 16 enter the frame 7 to work, and this cycle can realize non-stop production of carpets.

[0067] In the embodiment, the bottom of the limiting plate 162 is an inclined structure, such as Fig. 9 and Fig.10 As shown. When the hydraulic rod 8 brings the pressure plate 16 close to the bearing plate 11, as shown Fig. 9 As shown in a, the bottom slope of the limiting plate 162 contacts the edge corner of the supporting plate 11. Fig. 9 As shown in FIG. 2 b, as the pressing plate 16 moves downward, the limiting plate 162 rotates outward, as shown in FIG. Fig. 9 As shown by the middle arrow d, the limiting plate 162 is separated from the carpet until the limiting plate 162 moves to the outside of the carrying plate 11, as shown in FIG. Fig. 9 As shown in c, the carpet is in contact with the bearing plate 11, the support strip 10 and the support part 5 are inserted into the opening of the U-shaped rubber strip 4, and the support part 5 is fitted together with the top of the inner cavity of the U-shaped rubber strip 4 under the action of pressure, and the hydraulic rod 8 remains in an extended state, and the pressure plate 16 and the bearing plate 11 are kept under pressure for 5-10 minutes.

[0068] At the same time, the pressing plate 16 will exert pressure on the carpet, so as to press the surface layer and the backing of the carpet together, thereby improving the bonding effect between the surface layer and the backing.

[0069] After the pressing is completed, the hydraulic rod 8 contracts, the pressure on the upper end of the pressing plate 16 disappears, and the pressing plate 16 moves upward under the action of the spring 19. Fig.10As shown by the middle arrow, the pressing plate 16 is separated from the carrying plate 11. In the process of the pressing plate 16 moving upward, in the initial stage, since the limiting plate 162 contacts the side of the carrying plate 11, the carpet will be placed on the carrying plate 11. As the pressing plate 16 moves upward, the limiting plate 162 moves upward accordingly. When the limiting plate 162 moves to the edge of the carrying plate 11, the limiting plate 162 rotates inwardly under the action of the torsion spring, and the bottom of the limiting plate 162 contacts the edge of the carpet. Its trajectory is shown in FIG. Fig.10 As shown by the dotted line, since the carpet is made of flexible material, with a nylon surface layer and a flexible backing, under the action of the limit plate 162, the edge of the carpet will be lifted up and will not be stuck by the limit plate 162, and the carpet can be placed on the carrier plate 11. Thus, the bonding of the support part 5 and the U-shaped rubber strip 4 is completed. After the hydraulic rod 8 is retracted to the shortest state, the drive motor 14 is started, and the drive motor 14 moves the carrier plate 11, the pressing plate 16 and the carpet in the frame 7 to the outside, while the other carrier plate 11, the pressing plate 16, the support part 5 and the carpet move to the frame 7 for pressing.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
