Description

Technical Field

[0001] The utility model relates to the technical field of waterproof tarpaulin production, in particular to a roll-wrapped structure applied to waterproof tarpaulin. Background Art

[0002] Tarpaulin, also known as tarpaulin, is a waterproof material with high strength, good toughness, and flexibility. It is typically made of canvas (oil canvas), polyurethane-coated polyester, or polyethylene plastic. Tarpaulins often have sturdy grommets at the corners or edges for tying, hanging, or covering. During the production process, tarpaulin, due to its thin and long nature, needs to be rolled for easy transportation, which requires rolling equipment.

[0003] In order to facilitate the wrapping, the existing technology usually chooses to sleeve a wrapping tube on the wrapping shaft and drive the wrapping shaft to rotate to carry out the wrapping. However, the defects of this wrapping are:

[0004] 1. The diameter of the winding shaft in the prior art is fixed, so the diameter of the winding drum provided on its outer surface is also fixed. However, in actual applications, for long cloths, a winding drum with a larger diameter is often required, and for short cloths, a winding drum with a smaller diameter is selected for cost considerations. When encountering this problem, the fixed winding shaft in the prior art cannot be adapted according to actual production needs, thereby limiting its performance.

[0005] 2. Based on the above point, in the prior art, after the waterproof tarpaulin is rolled up, how to remove its chain belt roll from the roll shaft is also a problem. In the prior art, the roll shaft is often frequently disassembled and assembled to achieve the above purpose. However, this method is time-consuming and labor-intensive, and frequent disassembly and assembly will also accelerate its wear, which is not conducive to long-term use.

[0006] In view of this, it is necessary to improve the above defects.

[0007] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0032] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0033] Please refer to the instruction manual Figures 1 to 5The utility model discloses a rolling structure for waterproof tarpaulins, which mainly includes a rolling shaft component, a supporting component, a rotating drum 1 and a screw rod 2, a clamping component and a rotating component, wherein the rolling shaft component is a paper tube 3, which is hollow inside and has a layer of narrow double-sided tape on the outside. When in use, one side of the waterproof tarpaulin can be attached to it, and then the rolling shaft component is rotated to achieve rolling; the supporting component is used to support the entire device; the rotating drum 1 and the screw rod 2 are fixedly connected to each other and mounted on the supporting component; the clamping component is provided with at least two groups, which are respectively arranged on the periphery of the rotating drum 1 and the screw rod 2, and can achieve clamping and loosening of the rolling shaft component by adjustment; finally, the rotating component drives the above-mentioned rotating drum 1 and the screw rod 2 to rotate, thereby rolling.

[0034] To further explain the specific working principle of the present invention, in a preferred embodiment of the present invention, the support component includes a bearing seat 4 and a base 5. Two bearing seats 4 are provided, one located on either side of the base 5 and fixedly connected thereto. An extension 13 is provided at one end of the rotating drum 1 away from the screw rod 2. A bearing 14 is movably mounted in the bearing seat 4. Therefore, when the extension 13, the rotating drum 1, and the screw rod 2 are driven to rotate, the bearing 14 provides a support point. To drive the above components to rotate, the present invention provides a rotating component, which includes a pulley 15. The pulley 15 is fixedly connected to the extension 13. A pulley 2 is provided below the pulley 15. The pulleys 15 and 16 are connected to each other by a belt 17. A motor seat 18 is fixedly connected to the base 5. A motor 19 is fixedly connected to the motor seat 18. The output shaft of the motor 19 passes through the side wall of the base 5 and is fixedly connected to the pulley 2 16.

[0035] Next, in order to achieve the clamping and adjustment of the winding shaft component, the utility model is provided with a clamping component. Specifically, the clamping component includes two fixing rings 6, which are fixedly connected to both sides of the rotating drum 1. The screw rod 2 is threadedly connected to a threaded barrel 7, and the threaded barrel 7 is connected to a bearing 2 8. The bearing 2 8 and the fixing ring 6 are connected to the clamping and adjustment component through a rotating rod assembly. The clamping and adjustment component clamp plate 9 has an arc-shaped silicone portion 12 fixedly connected to the periphery of the clamp plate 9. The rotating rod assembly includes a rotating rod 10 and a rotating rod 2 11. The rotating rod 10 is used to connect the clamp plate 9 and the bearing 2 8, and the rotating rod 2 11 is used to connect the clamp plate 9 and the two fixing rings 6.

[0036] Therefore, by turning the threaded barrel 7 by hand or by using other components, the position of the threaded barrel 7 on the screw rod 2 can be changed under the influence of the threaded connection, thereby changing the relative position between the second bearing 8 and the fixed ring 6. At this time, since the length of the rotating rod 10 is fixed, and the relative position between the second bearing 8 and the fixed ring 6 changes, the distance between the splint 9 relative to the screw rod 2 or the rotating barrel 1 will change under the action of the Pythagorean theorem. The distance between the splints 9 and the splints 9 can be adjusted by changing several groups of splints 9 at the same time, so that the distance between them can be adjusted according to the rotation of the rod 10. The winding shaft components with different inner diameters are adjusted and clamped, or the clamping is released after the winding is completed. Finally, a handle 20 is fixedly connected to one side of the screw rod 2, and the entire equipment can be lifted by lifting the handle 20. When the winding is completed, the operator operates the clamping component to release the clamping, and the winding shaft component contacts the limit. At this time, the operator lifts the handle 20 and can lift the screw rod 2 and the components associated with the rotating drum 1 on one side, and the other side (that is, the right side of the fixed pulley 15) is drooped on the bearing seat 4, and the winding shaft component is removed from one side of the handle 20 to complete the winding process.

[0037] It should be noted that the electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0038] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
