Description

Technical Field

[0001] This utility model relates to the field of plastic tarpaulin technology, specifically to an anti-wrinkle plastic tarpaulin. Background Technology

[0002] Anti-wrinkle plastic tarpaulins are plastic tarpaulins with anti-wrinkle properties. They are less prone to wrinkling after use, better maintaining a flat appearance and performance, and are easy to store and unfold for reuse.

[0003] A search revealed that Chinese utility model patent application with publication number "CN216153983U" proposes "a cargo covering cloth for ship transportation." By using an Oxford cloth layer and a tarpaulin layer on its lower surface, the covering cloth possesses both fire-resistant and waterproof properties. Through the addition of a roller structure within a square hole for securing the covering cloth, the sliding friction between the securing rope and the covering cloth is transformed into static friction between the securing rope and the roller. The resistance to securing the covering cloth is no longer sliding friction, but rather the relatively small circumferential resistance of the rolling roller, making securing the covering cloth more effortless and convenient.

[0004] However, in actual use, the aforementioned devices and similar devices lack dynamic tensioning capability, which prevents the tension from being evenly distributed across the entire surface of the plastic tarpaulin, resulting in localized loosening of the plastic tarpaulin surface and subsequent wrinkle accumulation. Utility Model Content

[0005] The purpose of this invention is to provide an anti-wrinkle plastic tarpaulin to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-wrinkle plastic tarpaulin, comprising:

[0007] The reinforcing filling layer is stitched with an upper plastic tarpaulin layer. The reinforcing filling layer and the upper plastic tarpaulin layer together form the plastic tarpaulin base. Several condensers are stitched and embedded in the plastic tarpaulin base, and the condensers are equipped with interlaced wire harnesses.

[0008] The plastic tarpaulin substrate has several wire harness channels starting from the gatherer. The wire harness tape is inserted and matched with the wire harness channels, and the two ends of the inserted wire harness tape are fixed through the wire harness channels and the interior of the plastic tarpaulin substrate, respectively.

[0009] As the condenser operates, the interlacing wire harness is tensioned, thereby applying tension evenly to the plastic tarpaulin substrate through the wire harness channel, making the reinforcing filling layer and the upper plastic tarpaulin layer fit tightly together and reducing fabric slack.

[0010] Furthermore, the wire harness channels are arranged in a uniformly spaced grid structure within the plastic tarpaulin matrix, with multiple wire harness channels extending radially outward from the center of the coiler, and adjacent wire harness channels maintaining an equal distance from each other.

[0011] Furthermore, the wiring harness channels are arranged in an intermittent cross-design within the plastic tarpaulin substrate. That is, the wiring harness channels are intermittently connected at cross points within the plastic tarpaulin substrate. These cross points are periodically distributed along the channel path and intersect with adjacent channels. The surface of the interlaced wiring harness is exposed to the reinforcing filler layer on the surface or back of the plastic tarpaulin substrate based on the cross points.

[0012] Furthermore, as the condenser operates, the interlacing wire harness is dynamically tensioned at the cross connection points, causing localized stress concentration inside the plastic tarpaulin substrate. This tension is then efficiently transferred to the entire substrate surface through periodically distributed connection points, enabling the reinforcing filling layer and the upper plastic tarpaulin layer to form multi-point anchorage at the staggered positions, thus suppressing wrinkle formation.

[0013] Furthermore, a traction rope is movably connected inside the condenser and fixed to the interlacing wire harness. The two ends of the traction rope pass vertically through the top of the condenser and are fixed to the surface of the interlacing wire harness that passes laterally inside the condenser.

[0014] Furthermore, the periphery of the plastic tarpaulin substrate is stitched with reinforcing edge strips, which are tightly bonded to the edges of the reinforcing filling layer and the upper plastic tarpaulin layer to prevent edge wear and deformation.

[0015] Furthermore, the wire harness channels are arranged in a wavy curve structure within the plastic tarpaulin matrix, with multiple wire harness channels arranged in parallel and buffer gaps provided between adjacent channels to reduce local stress concentration during tensioning.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This wrinkle-resistant plastic tarpaulin uses a tufting device to drive the interlaced wire harness tape to dynamically tension within the wire harness channel, uniformly applying tension to the tarpaulin substrate. This ensures a tight fit between the reinforcing filling layer and the upper tarpaulin layer, eliminating fabric slack. Simultaneously, the mesh or wavy structure of the wire harness channel, combined with cross-connection points, creates a multi-point anchoring effect, efficiently transferring tension to the entire substrate surface, suppressing localized stress concentration and wrinkle formation, and improving deformation resistance and service life. The reinforced edge design further enhances edge stability, preventing wear and edge curling, ensuring the tarpaulin remains flat and aesthetically pleasing over long-term use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Before understanding the technical solution proposed in this application, it should be clear that the specific scenario in which the technical device proposed in this application is applied is open-air salt field covering operation, in which the plastic tarpaulin needs to be exposed to strong winds, sun and salt spray environment for a long time, and is prone to loosening and wrinkling due to external force or material fatigue.

[0024] like Figures 1-3 As shown, this utility model provides a technical solution: an anti-wrinkle plastic tarpaulin, comprising: a reinforcing filling layer 2, the surface of which is firmly connected to an upper plastic tarpaulin layer 1 by a sewing process, the two together constituting the core structure of the plastic tarpaulin substrate 5.

[0025] It is worth noting that in the technical solution proposed in this application, multiple gatherers 4 are embedded inside the plastic tarpaulin substrate 5 using a high-strength stitching method. Each gatherer 4 is equipped with an interlacing wire harness 3. These components work together to enhance the overall wrinkle resistance.

[0026] Specifically, the plastic tarpaulin base 5 has multiple wire harness channels starting from each condenser 4. These channels are precisely matched with the interlacing wire harness tape 3. The two ends of the interlacing wire harness tape 3 are inserted into the plastic tarpaulin base 5 through the wire harness channels and are firmly anchored by fixing mechanisms such as sewing or gluing to ensure that they do not loosen when the condenser 4 is in operation.

[0027] It should be added that when the condenser 4 is activated, the interlacing wire harness 3 is dynamically tensioned, generating a uniformly distributed tension. The tension is efficiently transmitted to the entire surface of the plastic tarpaulin substrate 5 through the wire harness channel, which promotes the tight adhesion between the reinforcing filling layer 2 and the upper plastic tarpaulin layer 1, effectively reducing fabric loosening and wrinkle formation.

[0028] Furthermore, as a preferred embodiment, in this technical solution, the arrangement design of the wire harness channels within the plastic tarpaulin substrate 5 adopts a multi-optimized structure: First, the channels are arranged in a uniformly spaced grid pattern, with multiple wire harness channels extending radially outward from the center of the coiler 4, maintaining a strict equidistant distance between adjacent channels to achieve uniform tension. Second, the channels can also adopt an intermittent cross design, that is, periodically distributed cross connection points are set inside the plastic tarpaulin substrate 5. These points are intermittently distributed on the channel path and intersect with adjacent channels. The surface of the wire harness strip 3 is exposed to the front or back area of ​​the reinforcing filling layer 2 at the cross connection points, depending on the position.

[0029] It should be added that, in this embodiment, during the operation of the condenser 4, the interlacing wire harness 3 is dynamically tensioned at the cross connection point, causing local stress concentration inside the plastic tarpaulin substrate 5. This concentrated force is efficiently dispersed to the entire substrate surface through the periodic connection point, so that the reinforcing filling layer 2 and the upper plastic tarpaulin layer 1 form a multi-point anchoring effect at the cross position, thereby significantly suppressing the formation of wrinkles.

[0030] To supplement the above, in this technical solution, a traction rope 6 is movably connected inside the choke 4. Both ends of the traction rope 6 extend vertically from the top of the choke 4 and are firmly fixed to the surface of the transversely passing wire harness 3, enhancing tension control accuracy. The periphery of the plastic tarpaulin base 5 is fixed with reinforcing edge bands using a high-strength stitching process. These edge bands are tightly bonded to the edges of the reinforcing filling layer 2 and the upper plastic tarpaulin layer 1, effectively preventing edge wear and deformation and improving overall durability.

[0031] Finally, it should be added that the wire harness channels are also arranged in a wavy curve structure, with multiple channels arranged regularly in parallel and buffer gaps set between adjacent channels to absorb local stress peaks during tensioning, further reducing the risk of stress concentration and ensuring the smooth and stable fabric surface.

[0032] In actual use, the technical device proposed in this application first operates the traction rope 6, pulling its two ends to activate the internal mechanism of the coiler 4, so that the threaded wire harness 3 is subjected to dynamic tension. At this time, the vertical movement of the traction rope 6 precisely controls the tension of the transverse threaded wire harness 3, ensuring that the tension is evenly transmitted to each wire harness channel of the plastic tarpaulin substrate 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
