Abstract
Description
Technical Field
[0001] This utility model relates to the field of floor grinding machine technology, and in particular to an automatic water-cooled floor grinding machine. Background Technology
[0002] A floor grinding machine is a multi-functional machine that integrates various processes such as rapid floor leveling, grinding, and polishing.
[0003] When grinding the floor, workers push the floor grinder to grind the area that needs grinding. The high-speed rotation of the grinding disc on the floor grinder can smooth and polish the uneven floor, thus achieving the desired floor treatment effect. However, the friction between the grinding disc and the floor generates high temperatures. Sustained high temperatures can cause the grinding disc to lose its cutting ability, resulting in a poorer floor treatment effect. In addition, the ground floor needs to be sprayed with water for curing, which leads to a certain waste of water resources.
[0004] Therefore, we provide an automatic water-cooled floor grinding machine. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned technical problems by providing an automatic water-cooled floor grinding machine that achieves both cooling and floor maintenance.
[0006] In view of this, the present invention provides an automatic water-cooled floor grinding machine, including a floor grinding machine, wherein a water tank is provided inside the floor grinding machine, and a water guide groove is provided on the lower surface of the water tank;
[0007] The water tank is equipped with one or more atomizing nozzles via a water pump on its periphery, and a rotating cavity is provided through the middle of the water tank.
[0008] A grinding disc is vertically installed below the water tank, and a water storage tank is formed on the upper surface of the grinding disc.
[0009] Preferably, the water guide channel is in the shape of a straight line and is inclined, and one end of the water guide channel extends to the outside of the floor grinder.
[0010] Preferably, the water guide channel has an inclination angle of 3° or greater and 6° or less, and the depth of the water guide channel is 3mm to 5mm.
[0011] Preferably, the distance between the water storage tank and the water guide tank is greater than or equal to 20cm and less than or equal to 30cm, and the depth of the water storage tank is 5cm.
[0012] Preferably, the motor output end passes through the interior of the rotating cavity and is fixedly connected to the upper end of the grinding disc. Preferably, the water outlet of the atomizing nozzle is located obliquely above the water storage tank.
[0013] Preferably, a guide plate is fixedly installed at the lower end of the floor grinding machine, and the guide plate is located below the water outlet of the water guide channel.
[0014] Compared with the prior art, this utility model provides an automatic water-cooled floor grinding machine, which has the following beneficial effects:
[0015] 1. This utility model, by setting a water storage tank, allows water to be retained inside, enabling the water to continuously cool the rotating grinding disc, thereby achieving a cooling effect.
[0016] 2. This utility model, by setting up a water guide channel with corrosion resistance and good temperature conduction, can quickly absorb the temperature of the water inside the water tank, thereby reducing its own temperature. At the same time, when water vapor moves upward and meets the channel, it can condense into water on it. The water can flow along the water guide channel to the polished floor, thereby achieving the effect of floor maintenance after polishing.
[0017] 3. This utility model, by setting the water guide channel in a straight line with an inclination angle greater than or equal to 3° and less than or equal to 6°, can quickly guide water, ensuring that the liquefied water is quickly discharged to the ground, thus achieving the effect of curing the floor. At the same time, if the inclination angle of the water guide channel is too small, the water flow speed will be slow. If the inclination angle is too large, the thickness of the lower surface of the water tank will be uneven, resulting in temperature difference on the lower surface of the water tank, which will not be effective in condensing water vapor. Therefore, using a water guide channel with a certain inclination angle can ensure that the water flows quickly to the polished floor, thereby further achieving the effect of floor curing.
[0018] 4. This utility model, by setting the depth of the water guide channel to 3mm to 5mm, addresses the issue that when the water guide channel is shallow, liquefied water cannot enter the channel and flow along it, or the flow speed is slow. When the water guide channel is deep, liquefied water may accumulate, resulting in slow flow. Furthermore, when the water guide channel is deep, dust may enter the channel during shutdown, causing blockage and significantly reducing the effectiveness of later use. Therefore, using a water guide channel with a certain angle and depth ensures that the liquefied water flows quickly and falls rapidly onto the polished floor, thus achieving the effect of floor maintenance.
[0019] 5. By setting the depth of the water tank to 5cm, this utility model can ensure that when the grinding disc rotates, the water inside the water tank will not be thrown out of the water tank in large quantities due to centrifugal force. At the same time, when the water volume is too large, the evaporation effect is not good, and when the water volume is too small, the cooling effect is poor. Therefore, by using a water tank of a certain depth, the effect of cooling the grinding disc and achieving the effect of condensation can be achieved.
[0020] 6. In this utility model, when the distance between the water storage tank and the water guide tank is greater than or equal to 20cm and less than or equal to 30cm, the surface temperature of the water guide tank will be affected by the temperature of the grinding disc when the distance between the water storage tank and the water guide tank is too close, resulting in poor condensation effect. When the water storage tank and the water guide tank are too far apart, some water vapor will be blown to one side by the wind and will not be able to condense into water at the water guide tank. Therefore, by adopting a certain distance between the water storage tank and the water guide tank, it can be ensured that the water vapor condenses into water at the water guide tank, thereby achieving a stable condensation effect.
[0021] 7. This utility model, by setting a guide plate, can receive and guide the water flowing out from the water channel, so that the water will not be blown onto the grinding disc due to changes in external airflow during the process of falling to the ground, resulting in less water falling to the ground, thereby ensuring that the water falls accurately to the ground and achieving the effect of ground curing.
[0022] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Example: An automatic water-cooled floor grinding machine, such as... Figure 1 - Figure 5 As shown, it includes a floor grinding machine 1, a water tank 4 is provided inside the floor grinding machine 1, and a water guide groove 7 is provided on the lower surface of the water tank 4;
[0032] The water tank 4 has one or more atomizing nozzles 3 installed around its perimeter via a water pump, and a rotating chamber 6 is provided through the middle of the water tank 4.
[0033] A grinding disc 2 is vertically installed below the water tank 4, and a water storage tank 5 is opened on the upper surface of the grinding disc 2.
[0034] The lower surface of water tank 4 and water guide channel 7 are made of a corrosion-resistant material with good thermal conductivity.
[0035] When water molecules are heated, they gain energy and their movement intensifies. Some water molecules overcome the binding force of the liquid and transform from a liquid state into gaseous water vapor. This process is called vaporization. When water vapor is cooled or pressurized, its molecular kinetic energy weakens and it aggregates to form liquid water droplets. This process is called liquefaction.
[0036] When the grinding disc 2 starts to rotate and grind, the atomizing nozzle 3 can spray water drawn from the water tank 4 by the water pump onto the upper part of the grinding disc 2. At the same time, the water can be stored in the water storage tank 5. The water stored in the water storage tank 5 cools down the grinding disc 2, which generates high temperature from continuous rotation, thereby achieving the effect of cooling the grinding disc 2. At the same time, the high temperature evaporates the water. Since the density of water vapor is less than that of air, the water vapor can move upward. At the same time, the water vapor meets the water guide channel 7 on the lower surface of the water tank 4. Depending on the material of the lower surface of the water tank 4, the temperature of the water in the water tank 4 is transferred to the lower surface of the water tank 4, which can make the temperature of the water guide channel 7 lower than the temperature of the water vapor. At this time, the water vapor can form water at the water guide channel 7. The water can flow along the water guide channel 7, flow through the water guide channel 7 and fall to the ground, thereby achieving the effect of curing the ground floor.
[0037] like Figure 1 - Figure 5 As shown, the water guide channel 7 is in the shape of a straight line and is inclined, and one end of the water guide channel 7 extends to the outside of the floor grinder 1.
[0038] The water guide channel 7 has an inclination angle greater than or equal to 3° and less than or equal to 6°, and the depth of the water guide channel 7 is 3mm to 5mm.
[0039] The straight-line water channel 7 can quickly guide water flow, ensuring that the liquefied water is quickly discharged to the ground, guaranteeing even curing of the floor. However, if the angle of inclination of the water channel 7 is too small, the water flow will be slow; if the angle is too large, the thickness of the lower surface of the water tank 4 will be uneven, leading to temperature differences and poor condensation of water vapor. Furthermore, if the depth of the water channel 7 is too shallow, the liquefied water will not flow smoothly or will flow slowly. If the depth of the water channel 7 is too deep, the liquefied water will accumulate, causing slow flow. Additionally, if the depth of the water channel 7 is too deep, dust will enter during machine shutdown, causing blockages and significantly reducing the effectiveness of later use. Therefore, using a water channel 7 with a certain angle and depth ensures that the liquefied water flows quickly and falls rapidly onto the polished floor, thus achieving the desired floor curing effect.
[0040] like Figure 1 - Figure 5 As shown, the distance between the water storage tank 5 and the water guide tank 7 is greater than or equal to 20cm and less than or equal to 30cm, and the depth of the water storage tank 5 is 5cm.
[0041] Water in the water tank 5 rises through high-temperature evaporation. When the water tank 5 is close to the water guide 7, the surface temperature of the water guide 7 is affected by the temperature of the grinding disc 2, resulting in poor condensation. When the water tank 5 is far from the water guide 7, some water vapor is blown to one side by the wind and cannot condense into water at the water guide 7. Therefore, a certain distance between the water tank 5 and the water guide 7 can ensure that water vapor condenses into water at the water guide 7, thereby achieving a stable condensation effect. At the same time, setting the depth of the water tank 5 can ensure that when the grinding disc 2 rotates, a large amount of water inside the water tank 5 will not be thrown out of the water tank 5 due to centrifugal force. Also, when the water volume is too large, the evaporation effect is poor, and when the water volume is too low, the cooling effect is poor. Therefore, using a water tank 5 of a certain depth can achieve the effects of cooling the grinding disc 2 and achieving condensation.
[0042] like Figure 1 - Figure 5 As shown, the motor output end passes through the inside of the rotating cavity 6 and is fixedly connected to the upper end of the grinding disc 2.
[0043] The water outlet of the atomizing nozzle 3 is located diagonally above the water storage tank 5.
[0044] By setting the rotating cavity 6, it is possible to ensure that the motor output drives the grinding disc 2 to rotate, while also preventing corrosion. At the same time, the atomizing nozzle 3 above the water storage tank 5 can spray water into the water storage tank 5 through a water pump, thereby cooling the grinding disc 2. Meanwhile, the position of the atomizing nozzle 3 will not affect the normal movement of water vapor, preventing water vapor from condensing prematurely at its location due to its own temperature, which would result in less condensate at the water guide tank 7. Therefore, by setting the position of the atomizing nozzle 3, the condensation effect can be ensured to be stable.
[0045] like Figure 1 - Figure 5 As shown, a guide plate 8 is fixedly installed at the lower end of the floor grinder 1, and the guide plate 8 is located below the water outlet of the water guide channel 7.
[0046] The guide plate 8 can receive and guide the water flowing out of the water channel 7, so that the water will not be blown onto the grinding disc 2 due to changes in external airflow during the process of falling to the ground, resulting in less water falling to the ground. Therefore, by setting the guide plate 8, it can be ensured that the water falls to the ground accurately, thereby achieving the effect of ground curing.
[0047] Working principle: When the floor grinding begins, the grinding disc 2 starts to rotate, the atomizing nozzle 3 starts to spray water, the water in the water tank 5 is evaporated by the grinding disc 2 and moves upward. The water vapor encounters the water guide 7 which has cooled down and condenses into water. The water flows along the water guide 7 and falls onto the guide plate 8. The water falls to the ground through the guide plate 8.
[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
