Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a roller device for covering concrete film. Background Art

[0002] Architecture is a general term for buildings and structures. It is an artificial environment created by people to meet the needs of social life using the material and technological means at their disposal, incorporating certain scientific principles, feng shui concepts, and aesthetic principles. Currently, concrete is widely used in construction. Concrete is a general term for engineering composite materials composed of aggregates bonded together by a binder. Concrete is commonly referred to as cement concrete, which is made by mixing cement as the binder, sand and stone as aggregates, and water in a specific proportion.

[0003] In order to ensure the visual quality of concrete, concrete is mainly covered with a film during the second finishing to prevent rapid loss of moisture in the concrete and play a role in thermal insulation and maintenance. The traditional construction method is to cover it after the manual second finishing is completed, but it is usually operated by two or more people. During the operation, there is a large friction between the film and the concrete, the operation is complicated, time-consuming and labor-intensive, and the work efficiency is slow.

[0004] In response to the above problems, we proposed a roller device for concrete film covering, which is easy to operate and improves the construction efficiency of workers. Utility Model Content

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, a typical embodiment of the present invention provides a roller device for covering concrete film, including a bracket 1, a reversing roller 2 is provided at the front end of the bracket 1, a mounting groove 3 for mounting a film roller is provided at the rear end of the bracket 1, a hand lever 4 is provided on the bracket 1 for pushing the bracket 1 to move, and the release end of the film on the film roller passes through the reversing roller 2 from top to bottom and then passes through the bottom of the film roller backward.

[0028] During the process of covering the concrete with film, the reversing roller 2 and the film roller both roll on top of the film spread on the concrete, and the reversing roller 2 can cooperate with the film roller to tighten the film, which not only improves the laying effect of the film, but also the reversing roller and the film roller support the bracket 1 at the same time, making the operation more convenient and easier to ensure the consistency of the laying direction, thereby improving the film laying effect.

[0029] The bottom end of the handle bar 4 is rotatably connected to the bracket 1. In this arrangement, when the handle bar 4 is pulled forward during the laying of the film, the handle bar 4 can lower the center of gravity by rotating forward, which can effectively prevent the film roller from warping.

[0030] A slide 5 is slidingly provided at the front end of the bracket 1, and a core shaft 6 is rotatably installed on the slide 5. The reversing roller 2 is rotatably sleeved outside the core shaft 6. A front push plate 7 sliding in the bracket 1 is provided on the front side of the slide 5. The front push plate 7 is connected to the carrying rod 4 through a front connecting rod 8, and when the top end of the carrying rod 4 swings forward, the front push plate 7 pushes the slide 5 to move forward.

[0031] During the process of laying the film, when the hand lever 4 is pulled forward, the hand lever 4 swings forward, causing the front connecting rod 8 to push the front push plate 7 to move forward. At this time, the front push plate 7 pushes the slide 5 forward, and the slide 5 causes the reversing roller 2 to produce a forward movement trend or displacement on the bracket 1 through the core shaft 6. This not only ensures that the reversing roller 2 always has the tensioning force on the film, but also can appropriately control the tensioning force of the film by controlling the swing amplitude of the hand lever 4, so as to better carry out the film laying operation.

[0032] In a relatively specific embodiment, the bottom end of the front connecting rod 8 is rotatably connected to the front push plate 7 , and the top end of the front connecting rod 8 is rotatably connected to the carrying handle 4 .

[0033] The front side of the slide 5 is connected to a front spring 9, and when the slide 5 moves forward, the front spring 9 is stretched. The elastic force of the front spring 9 provides a certain support for the handrail 4, which can prevent the handrail 4 from swinging forward too much, causing the film to be forcibly pulled and deflected or deformed or broken.

[0034] An upwardly open arcuate groove 10 is provided within the mounting groove 3. The end of the film roller is placed within the arcuate groove 10. A limit shoe 11 is mounted on the top of the arcuate groove 10 and is sleeved over the end of the film roller. The limit shoe 11 cooperates with the arcuate groove 10 to surround the end of the film roller, ensuring a stable installation of the film roller on the bracket 1.

[0035] The rear end of the retaining shoe 11 is pivotally connected to the rear end notch of the arcuate slot 10. A positioning hole 12 is defined at the rear end of the retaining shoe 11. A positioning rod 13 is inserted into the positioning hole 12. A positioning spring 14 is connected to the front end of the positioning rod 13, providing a force for the rod 13 to be inserted into the positioning hole 12. The positioning spring 14 ensures that the positioning rod 13 is inserted into the positioning hole 12. In this state, the positioning rod 13 secures the retaining shoe 11 in a position surrounding the film roller, ensuring a stable installation of the film roller on the bracket 1. Furthermore, by pushing the positioning rod 13 backward to remove it from the positioning hole 12 and then opening the retaining shoe 11, the film roller can be removed from the mounting slot 3, allowing for easy replacement.

[0036] The rear side of the carrying rod 4 is rotatably connected to a rear connecting rod 15, and the bottom end of the rear connecting rod 15 is rotatably connected to a rear push plate 16. The rear push plate 16 is slidably installed in the bracket 1, and when the carrying rod 4 swings backward, the rear connecting rod 15 pushes the positioning rod 13 out of the positioning hole 12.

[0037] By pushing the carrying rod 4 backward and swinging the carrying rod 4 backward, the rear push plate 16 is pushed backward by the rear connecting rod 15, and the rear push plate 16 can push the positioning rod 13 backward and make the positioning rod 13 be pulled out of the positioning hole 12. At the same time, the eccentric force when the carrying rod 4 tilts backward is used to keep the positioning spring 14 in a stretched state, so that the positioning rod 13 is stably maintained in the position of being out of the positioning hole 12. Furthermore, in the process of replacing the film roller, the limit tile 11 is better kept in the open state, which is more convenient for replacing the film roller.

[0038] The outer end surface of the stop shoe 11 extends beyond the end of the film roller, and a push rod 17 is provided on the front side of the positioning rod 13. The push rod 17 is used to push the stop shoe 11 open after the positioning rod 13 is withdrawn from the positioning hole 12. This arrangement eliminates the need for a worker to open the stop shoe 11 separately. In actual operation, the worker only needs to push the handle 4 backward to withdraw the positioning rod 13 from the positioning hole 12 and open the stop shoe 11.

[0039] A pressure rod 18 is provided on the positioning rod 13 . The pressure rod 18 is located at the rear side of the limiting tile 11 . The pressure rod 18 is used to close the limiting tile 11 before the positioning rod 13 is inserted into the positioning hole 12 .

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
