Description

Release agent brushing device

Technical Field

The application belongs to a brushing device, and particularly relates to a release agent brushing device.

Background

The release agent is a functional substance between the mould and the finished product, and can be coated on the surface of the concrete mould, and the release agent has the function of separating the concrete from the mould, so as to facilitate the dismantling of the mould, thereby avoiding the adhesion between the concrete and the mould. In addition, the release agent has no adverse effect on the concrete surface, and can ensure the smoothness, uniformity and beautiful appearance of the concrete surface. The release agent can prevent the problems of cracking, breakage, stripping and the like on the surface of the concrete, and simultaneously can reduce the damage and abrasion of the template.

In building construction, in order to facilitate the removal of a concrete form, a release agent needs to be smeared on the surface of the form. The conventional brushing method is to dip the release agent liquid by using a rolling brush and then directly paint the release agent liquid on the surface of the template. However, when the mold release agent is applied in this way, the amount of the roll brush dipped in the mold release agent gradually decreases during the application process, resulting in uneven application of the mold plate to each portion. If the demoulding agent is too much, the surface of the concrete test piece is easy to be provided with more bubbles, and if the demoulding agent is too little, the demoulding of the concrete test piece is not facilitated, and the expected effect cannot be achieved. For tall templates, a ladder is also required to apply the release agent. In addition, the long-time placement of the release agent can lead to the phenomenon of precipitation and uneven concentration, and the release agent needs to be fully stirred at the moment, and the traditional method is generally to manually stir the storage vat by taking a long rod, so that the method is time-consuming and labor-consuming. Meanwhile, the rolling brush is easy to drop to the ground when dipping the release agent liquid from the release agent container, so that the waste of the release agent is caused, and the building site or the experimental site is stained, thereby causing inconvenience for subsequent work. Therefore, most of the inventors can avoid the use of a rolling brush to dip the release agent liquid and quantitatively supply the release agent by arranging the release agent container and the electric valve, thereby effectively avoiding the waste of the release agent.

Typically, as in the application of chinese publication No. CN208303157U, the inventor fixedly installs the release agent container on the main body rod, and communicates the release agent container with the hollow guide rod, so that the hollow guide rod is used as a liquid inlet channel of the release agent for the aluminum die, which not only greatly simplifies the structure of the brushing tool and is convenient to carry, but also effectively avoids the waste of the release agent from the liquid inlet inside the brushing roller assembly. However, in the using process of the device, the release agent container is detached for charging after being used for a period of time, and the release agent container is arranged on the rod piece of the brushing main body, so that the weight of the brush rod is increased. In the process of brushing, the method not only has the function of reducing labor intensity, but also can not solve the problem of uneven concentration caused by layering of the release agent. In addition, the inventor can control the liquid inlet amount by liquid inlet from the inside of the roller, but the uneven brushing phenomenon can occur on the surface of the roller due to the speed of brushing or the length of the rest time.

In view of the above, it is necessary for the inventor to design a mold release agent brushing apparatus which is free from frequent feeding, is uniformly smeared, and can automatically adjust the length.
