DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 3 ,in, Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is the overall right side view of the first embodiment of the utility model. Figure 3 The utility model Figure 2 AA line section view.

[0024] The utility model provides a flexible anti-impact wind tube coated cloth, comprising a first PVC film layer 101, a first paste resin 102, a bulletproof fiber skeleton layer 103, a second paste resin 104 and a second PVC film layer 105, wherein the bulletproof fiber skeleton layer 103 comprises a plurality of transverse warp yarns 106 distributed transversely and a plurality of longitudinal weft yarns 107 distributed longitudinally.

[0025] According to the present specific embodiment, the first paste resin 102 is arranged above the bulletproof fiber skeleton layer 103, the first PVC film layer 101 is fixedly connected to the first paste resin 102 and is located above the first paste resin 102, the second paste resin 104 is arranged below the bulletproof fiber skeleton layer 103, the second PVC film layer 105 is fixedly connected to the second paste resin 104 and is located below the second paste resin 104, high-strength aramid fiber is used as the connecting layer, i.e. the bulletproof fiber skeleton layer 103, and polyvinyl chloride resin explosion-proof films are used on the upper and lower surfaces, and then the first paste resin 102 and the second paste resin 104 are coated on the upper and lower sides of the bulletproof fiber skeleton layer 103, and the upper and lower layers of polyvinyl chloride resin films are firmly bonded to the bulletproof fiber skeleton layer 103 by high-temperature plasticization, so as to improve the strength of the barrel material, thereby improving its own shell collapse resistance, impact resistance, weather resistance and folding resistance, prolonging the service life, saving the time and manpower of workers to replace the wind tube, reducing the labor intensity of workers, and improving the work efficiency of workers.

[0026] The main components of the first PVC film layer 101 and the second PVC film layer 105 are polyvinyl chloride, which is slightly yellow and translucent, shiny, and more transparent than polyethylene and polypropylene, but less transparent than polystyrene. Depending on the amount of additives used, it can be divided into soft and hard polyvinyl chloride. The soft product is soft and tough, and feels sticky. The hardness of the hard product is higher than that of low-density polyethylene, but lower than that of polypropylene, and whitening will occur at the inflection point.

[0027] The first paste resin 102 and the second paste resin 104 are mainly a special resin, usually referring to polyvinyl chloride (PVC) paste resin. This resin is mainly used in the form of a paste. The texture of polyvinyl chloride paste resin is similar to talcum powder and has non-flowability. In the unprocessed state, it is a unique liquid form of polyvinyl chloride plastic. Polyvinyl chloride paste resin is usually prepared by emulsion and microsuspension method. After this resin is mixed and stirred with a plasticizer, a stable suspension can be formed, which is called PVC paste or PVC plastisol, PVC sol. During the processing, various fillers, diluents, heat stabilizers, foaming agents and light stabilizers can be added according to different product requirements. The development of the PVC paste resin industry provides a liquid material that can be converted into polyvinyl chloride products only by heating. This material is easy to configure, stable in performance, easy to control and easy to use. The product performance is excellent, the chemical stability is good, and it has certain mechanical strength and easy coloring.

[0028] Polyvinyl chloride resin film is made of polyvinyl chloride resin and other modifiers through calendering or blow molding process. The general thickness is 0.08-0.2mm. The thickness greater than 0.25mm is called PVC sheet. Functional processing aids such as plasticizers, stabilizers, lubricants, etc. are added to PVC resin and calendered into film. This kind of greenhouse film has good thermal insulation and light transmittance, is soft and easy to shape, and is suitable as an external covering material for greenhouses, sheds and small and medium-sized sheds.

[0029] The prepared first paste resin 102 and the second paste resin 104 are dip-coated on the bullet-proof fiber skeleton layer 103 by a coating process, and are appropriately dried and plasticized in an oven and a large vat at a certain temperature to form a bonding layer on the upper and lower surfaces of the bullet-proof fiber skeleton layer 103, which is firmly bonded to the upper and lower layers of polyvinyl chloride resin explosion-proof films that have been fully plasticized, to form a high-strength, tear-resistant, and wear-resistant impact-resistant coated cloth.

[0030] Among them, a plurality of transverse warp yarns 106 and a plurality of longitudinal weft yarns 107 are interlaced with each other, and the transverse warp yarns 106 and the longitudinal weft yarns 107 are respectively fixedly connected to the first paste resin 102 and the second paste resin 104, and are respectively located between the first paste resin 102 and the second paste resin 104. A plurality of the transverse warp yarns 106 and the plurality of the longitudinal weft yarns 107 are interlaced with each other to form the bulletproof fiber skeleton layer 103, which are all made of aramid fiber, with different warp and weft densities designed, and a plain weave structure is adopted. The warp and weft fibers are interwoven together through a loom. The organization formed by the longitudinal weft yarns 107 and the transverse weft yarns interwoven alternately one above and one below is called a plain weave, which has the most interlacing points, and the fabric is strong, does not deform, is wear-resistant, and is not easy to be abraded.

[0031] Aramid fiber is called "aromatic polyamide fiber", which refers to long-chain synthetic polyamide fiber with more than 85% amide bonds directly connected to the benzene ring. Amide bonds are aromatic rings or aromatic ring derivatives, and are a new type of special polymer material. There are two types of aramid fibers that have been widely commercialized on the market, namely meta-aramid fiber and para-aramid fiber. Aramid fiber has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is twice that of steel wire, and its weight is only about 1 / 5 of that of steel wire.

[0032] When the flexible anti-impact wind tube coating cloth of the utility model is used, a plurality of the transverse warp yarns 106 and a plurality of the longitudinal weft yarns 107 are interlaced to form the bulletproof fiber skeleton layer 103, both of which are made of aramid fiber, with different warp and weft densities designed, and a plain weave structure is adopted. The warp and weft fibers are interwoven together by a loom, and the tissue formed by the longitudinal weft yarns 107 and the transverse weft yarns interwoven alternately one above and one below is called a plain weave, and polyvinyl chloride resin explosion-proof films are adopted on the upper and lower surfaces, and then the first paste resin 102 and the second paste resin 104 are coated on the upper and lower sides of the bulletproof fiber skeleton layer 103, and the upper and lower layers of polyvinyl chloride resin films are firmly bonded to the bulletproof fiber skeleton layer 103 by high-temperature plasticization, so as to improve the strength of the barrel material, thereby improving its own shell collapse resistance, impact resistance, weather resistance and folding resistance, prolonging the service life, saving the time and manpower of workers to replace the wind tube, reducing the labor intensity of workers, and improving the work efficiency of workers.

[0033] Second embodiment:

[0034] Based on the first embodiment, please refer to Figures 4 to 6 ,in, Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the utility model. Figure 5 It is the overall right side view of the second embodiment of the utility model. Figure 6 The utility model Figure 5 BB line cross-sectional view.

[0035] The utility model provides a flexible impact-resistant wind tube coated cloth, which also includes a connecting component 201 and a frosting component 202, wherein the connecting component 201 includes a connecting plate 203, a connecting frame 204, a spring 205, a movable plate 206, a concave plate 207 and a docking component 208, wherein the docking component 208 includes a mounting seat 209 and a convex plate 210, the frosting component 202 includes a frosting plate 211 and two side ear plates 212, and the connecting frame 204 has a slide groove 213.

[0036] For this specific embodiment, the connecting component 201 is arranged at one end of the transverse warp yarn 106, and the frosting component 202 is arranged above the connecting frame 204. The connecting component 201 is added to facilitate the processing personnel to connect the two ends of the coated cloth and quickly make it into a hair dryer, while the frosting component 202 is to prevent the staff from slipping.

[0037] The connecting plate 203 is fixedly connected to the transverse warp yarn 106 and is located at one end of the transverse warp yarn 106. The connecting frame 204 is fixedly connected to the connecting plate 203 and is located on one side of the connecting plate 203. The connecting frame 204 has a slide groove 213, and the slide groove 213 is movably matched with the movable plate 206. One end of the spring 205 is fixedly connected to the connecting frame 204 and is located on the inner top wall of the slide groove 213. The other end of the spring 205 is fixedly connected to the movable plate 206 and is located above the movable plate 206. The concave plate 207 is connected to the movable plate 206. 06 is fixedly connected and is located below the movable plate 206. The docking component 208 is arranged at one end of the transverse warp yarn 106 away from the connecting plate 203. The docking component 208 is inserted into the connecting frame 204. At this time, the concave plate 207 moves upward in the slide groove 213, and the spring 205 is compressed. When the docking component 208 cannot move, the reaction force of the spring 205 will firmly hold the concave plate 207 in contact with the docking component 208. The two ends of the coated cloth are connected in this way, so that it can be quickly rolled into a wind tube, which effectively reduces the workload of the staff.

[0038] Secondly, the mounting seat 209 is fixedly connected to the transverse warp yarn 106 and is located at one end of the transverse warp yarn 106 away from the connecting plate 203. The protruding plate 210 is fixedly connected to the mounting seat 209 and is located on one side of the mounting seat 209. The protruding plate 210 contacts the concave plate 207 to lock the protruding plate 210 and prevent the protruding plate 210 from loosening.

[0039] At the same time, the frosted plate 211 is fixedly connected to the connecting plate 203 and is located above the connecting frame 204. The two side ear plates 212 are fixedly connected to the connecting frame 204 and are respectively located at the upper and lower ends of the connecting frame 204. The cooperation between the side ear plates 212 and the frosted plate 211 prevents the staff from slipping when taking the connecting frame 204.

[0040] When using a flexible impact-resistant wind tube coated cloth of the utility model, the convex plate 210 is inserted into the connecting frame 204. At this time, the concave plate 207 moves upward under the support of the convex plate 210, causing the spring 205 to be compressed. When the convex plate 210 fits with the concave plate 207, the reaction force of the spring 205 will firmly support the concave plate 207 and contact the convex plate 210. Connecting the two ends of the coated cloth in this way is convenient for processing personnel to quickly make an air tube, effectively reducing the workload of workers. The cooperation of the side ear plate 212 and the frosted plate 211 prevents the staff from slipping when taking the connecting frame 204.

[0041] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
