Description

Technical Field

[0001] This utility model relates to the field of ring saw technology, specifically to a wall-cutting ring saw pressure wheel with a drainage structure. Background Technology

[0002] The circular saw is a commonly used tool in modern construction, capable of cutting various walls and stone materials. However, during use, the cutting area requires continuous water spraying to cool the saw blade. Figure 1 The image shows an existing ring saw, where A is the pressure roller, as shown. Figure 2 As shown, B is the mounting post of the pressure roller. The front end of the pressure roller A is a sleeve-shaped structure that fits on the outside of the mounting post B. In order to rotate, a certain gap needs to be left between the two. During use, water mixed with debris and other impurities can easily flow in through the gap, but it is difficult to flow out directly. Due to the small gap, according to the inverse relationship between flow rate and cross-sectional area, it can be concluded that the water can only flow out slowly, or the water can directly evaporate into water vapor and be discharged. The above phenomena will cause impurities to be deposited in the gap between the pressure roller A and the mounting post B, causing resistance when the pressure roller A rotates, resulting in poor operation or even jamming. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed wall-cutting annular saw pressure wheel with a drainage structure to address the defects and shortcomings of the existing technology, which can solve the above-mentioned defects.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes pressure rollers mounted on the main body of the ring saw via mounting columns. The pressure rollers are all located on the side of the saw blade of the ring saw body and guide it. Several drainage holes are opened on the front end face of the pressure rollers.

[0005] Preferably, a plurality of the drain holes are evenly distributed along the circumference on the front end face of the pressure roller.

[0006] Preferably, all of the drain holes are through holes.

[0007] Preferably, all of the drain holes are round holes.

[0008] The beneficial effects of this utility model after adopting the above structure are:

[0009] This invention allows water entering the pressure roller to be discharged in a timely manner by opening a drain hole in front of the pressure roller, which also carries away impurities. This prevents the accumulation of impurities in the gap between the pressure roller and the mounting column, which could lead to increased operating resistance or even jamming. This improves efficiency and has a simple structure. Attached Figure Description

[0017] 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.

[0018] See Figures 1-5 As shown, it includes a pressure roller 4 mounted on the ring saw body 1 via a mounting post 3. The pressure roller 4 is located on the side of the saw blade 2 of the ring saw body 1 and guides it. Six dry drainage holes 5 are opened on the front end face of the pressure roller 4. The drainage holes 5 are all circular through holes. The six drainage holes 5 are evenly distributed along the circumference on the front end face of the pressure roller 4.

[0019] During use, due to the large inner and outer diameters of the drain hole 5 and the pressure roller 4, the outflow speed of water is no longer restricted. Water and impurities entering the pressure roller 4 can automatically flow out from the drain hole 5 during the stationary or rotating process of the pressure roller 4 due to gravity, centrifugal force and other forces. Moreover, the flow of water can enhance the discharge effect of impurities. Therefore, impurities in the water are difficult to deposit in the gap between the pressure roller 4 and the mounting column 3, thereby preventing the pressure roller 4 from increasing the operating resistance or even jamming due to the deposition of impurities in the gap.

[0020] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.
