Description

Technical Field

[0001] The invention relates to the technical field of concrete construction, and in particular to a concrete film coating machine and a use method thereof. Background Art

[0002] Traditional concrete covering work generally relies on manual labor. The construction process is not only time-consuming and labor-intensive, but also easily leads to problems such as uneven coverage and poor membrane quality due to the instability of manual operation, thus affecting the hardening process and final quality of the concrete.

[0003] With the development of automation and robotics, concrete coating machines are gradually being used in the construction industry. Using concrete coating machines can significantly improve construction efficiency and reduce labor costs. It can also improve the quality and consistency of the film layer and ensure that the concrete is optimally protected during the curing process. In addition, concrete coating machines can work stably in harsh construction environments, reducing the labor intensity of construction workers and the risk of exposure to dangerous environments. Especially in large-scale construction projects, coating machines can cope with large-area construction needs and save a lot of time and human resources.

[0004] However, traditional coating machines generate large disturbances on the concrete surface, which may lead to uneven coating effects on the concrete surface; most of them use manually controlled equipment, which will leave footprints on the concrete surface during use, which may cause cracks in the initial setting concrete and affect its quality. For example, there is currently a Chinese patent application publication number CN107956291A that discloses a concrete coating tool that needs to be pushed manually and still has the problem of leaving footprints on the concrete surface. Summary of the invention

[0005] The object of the present invention is to provide a concrete film coating machine and a method of using the same to solve the above problems in view of the above shortcomings and defects of the prior art.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] A concrete film covering machine, comprising:

[0008] A dock for connecting to a mobile device;

[0009] A film feeding device disposed on the base;

[0010] A film cutting device is arranged on the base, and is used for cutting the film delivered by the film delivering device.

[0012] In a preferred embodiment of the present invention, the film feeding device includes a film unwinding roller, a driving roller, a driven roller, and a follower roller arranged on the base. The driving roller and the driven roller are arranged at intervals up and down and tangentially matched. A film passing channel is formed between the driving roller and the driven roller for the film coming out of the film unwinding roller to pass through. After the film passes through the film passing channel and fits with the concrete surface, the follower roller squeezes the film.

[0016] In a preferred embodiment of the present invention, a vibration mechanism is provided on the base, and the vibration mechanism is arranged at the front end of the base in the forward direction. The vibration mechanism causes mud to be generated on the concrete surface due to vibration, which helps the film to adhere.

[0017] In a preferred embodiment of the present invention, the vibration mechanism includes a vibration plate floatingly connected to the base and a vibration motor disposed on the vibration plate.

[0018] In a preferred embodiment of the present invention, the front end of the vibration plate is arranged as an arc-shaped pressing edge to facilitate further smoothing of the concrete surface.

[0019] A method for using the concrete film coating machine as described in any of the above technical solutions comprises the following steps:

[0021] 2) Install the finished film on the film feeding device, unfold the finished film, and flatten the end of the film and place it on the concrete surface;

[0022] 3) The mobile device drives the base to move, continuously output the film, and completely adhere the film to the concrete surface;

[0023] 4) After the lamination of a section of film is completed, the film cutting device cuts the film delivered by the film feeding device to complete a lamination action;

[0024] 5) The film cutting device returns to the initial position and enters the next film laminating cycle.

[0025] Due to the adoption of the above technical solution, the present invention changes the film laminating operation mode of the manual semi-automatic film laminating equipment to one-key remote control operation mode, and can be used in conjunction with a mobile device (such as a vehicle). After completing the film laminating of a section of area, the film laminating work of the next operation surface can be carried out without manual assistance, and automatic cutting and film automatic output are realized, and "zero pressure" film laminating is completed, and there will be no problem of leaving footprints on the concrete surface, which greatly reduces the labor intensity, saves manpower, and improves the operation efficiency.
