Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of block polishing equipment, in particular to autoclaved aerated concrete block polishing equipment. Background Art
[0002] Aerated concrete blocks are a new type of lightweight and porous building material that combines lightweight, thermal insulation, fire resistance, earthquake resistance, and sound insulation and sound absorption. The blocks are mainly made of a mixture of raw materials such as cement, lime, sand, and expansion agent. They are light in weight and can effectively reduce the weight of the building. At the same time, they have low thermal conductivity and excellent thermal insulation effects. Aerated concrete blocks also have good fire resistance and can withstand high temperatures, meeting the national first-level fire protection standards. During an earthquake, they have good integrity and are not easy to collapse, providing a certain degree of earthquake resistance for the building. In addition, their porous structure can effectively absorb noise and create a quiet living environment. This type of block is easy to process and can be nailed, sawed, planed, and other operations can be performed according to construction needs. It is suitable for the construction of various building enclosure walls and partition walls. Aerated concrete blocks have become an indispensable and important material in modern architecture with their excellent performance and wide range of applications.
[0003] During the polishing process of aerated concrete blocks, most of them are polished manually with low work efficiency. When using machinery for polishing, especially when polishing on both sides of the block at the same time, it is necessary to ensure that the force is moderate and the angle is appropriate to prevent unnecessary damage to the surface of the block. Excessive force may cause scratches or breakage on the surface of the block, while too little force may not achieve the expected polishing effect. In particular, it is necessary to pay attention to the fact that the forces applied to the blocks by the equipment on both sides should be the same to avoid tilting during the polishing process that may cause the product to be scrapped. In addition, a large amount of dust will be generated during the polishing process, and spraying with water will easily form mud that flows into the pores and solidifies, resulting in a decrease in product quality.

[0006] Preferably, a magnetic-resistance layer for isolating the magnetic field is provided between the movable tube and the connected magnet, and is made of, for example, a rubber-based composite material, which can not only isolate the magnetic field effect caused by the magnet on the motor and grinding wheel connected to the movable tube, but also absorb vibration shock, thereby achieving a balance between magnetic field isolation and mechanical stability.

[0008] Preferably, a suction port is provided in the depression in the base, and the suction force generated can suck the mist droplets sprayed from the nozzle into it.
[0009] Preferably, baffles are provided on both sides of the base.

[0010] Preferably, an infrared rangefinder for detecting the distance to the polished workpiece is provided next to the polishing assembly.
[0011] (III) Beneficial effects: Compared with the prior art, the utility model provides an autoclaved aerated concrete block polishing device, which has the following beneficial effects:
[0012] 1. The autoclaved aerated concrete block polishing equipment transports the polishing piece to the polishing assembly through a guide rail, and uses an electromagnetic module to generate the same magnetism as the magnet on the movable tube for driving. The movable tube drives the grinding wheel to be pushed out. After contacting the polishing piece, the motor drives the grinding wheel to rotate to polish the surface. At the same time, the electromagnetic module is used to increase the magnetic field strength and increase the repulsive force between the magnets, so that the grinding wheel generates pressure on the surface of the polishing piece, thereby improving the polishing efficiency. The internal magnetic field strength is detected by the magnetic field detector in the sleeves on both sides. The closer two magnets with the same magnetic properties are, the denser the magnetic flux lines will be, and the sparser the magnetic flux lines will be when the distance becomes farther. Through this change, the distance between the two magnets is detected to determine whether the grinding wheels on both sides have a strong influence on the polishing piece. Whether the pressure applied is the same, avoid excessive pressure on one side of the polishing component, which will cause the polishing depth on one side of the polishing part to be too deep, or cause the polishing part to be pushed and offset, damaging the grinding wheel on the other side, so that the grinding wheels on both sides can apply uniform pressure to the polishing part for polishing. In addition, the overall polishing component is electromagnetically driven, and the control is more flexible and precise. Compared with hydraulic control, the equipment structure is simpler, the cost is lower, the distance adjustment is more precise, and the response time is faster. There is no risk of leakage, and the equipment maintenance is more convenient. Moreover, through the detection effect of the magnetic field detector, even if the equipment is worn and the adjustment ability is reduced due to the increase in the use time, the actual distance can be effectively detected and adjusted, which increases the control accuracy and service life.
[0013] 2. The autoclaved aerated concrete block polishing equipment is provided with a water pipe above the polishing assembly, and the water pipe is arranged with nozzles capable of spraying mist water droplets. When the mist water droplets adhere to the dust generated by the polishing piece during the polishing process, the mist water droplets can moisten and settle the dust, thereby reducing the dust content in the air, improving the working environment, and protecting the health of the operators. The base is provided with an air intake at the concave part, and the suction force generated can suck the mist water droplets sprayed by the nozzle into it, and the suction force generated by the air intake is used to suck the water droplets attached with dust into it, thereby avoiding Dust combines with a large amount of water to form mud, which flows into the pores in the blocks. The mud solidifies in the pores, which will cause the overall product quality of the bricks to decline. The mist droplets can effectively reduce the heat generated during the polishing process. At the same time, compared with directly spraying the surface of the blocks with water, polishing with mist droplets can reduce the waste of water resources. The mist droplets have a wider coverage area and can make better use of water resources. In addition, this method also helps to reduce the use of chemical polishing agents, reduce environmental pollution, and can achieve the effect of reducing dust, wetting the polishing surface and cooling the equipment.

[0019] See also Figure 1-Figure 3A autoclaved aerated concrete block polishing device comprises a base 1, a depression is provided at the center of the base 1, a guide rail for transporting blocks is provided in the depression, polishing components 11 are provided on the base 1 on both sides of the guide rail, the polishing components 11 are composed of a sleeve 111, a movable tube 112, a grinding wheel 113 and an electromagnetic module 114, the polishing component 11 is provided with a sleeve 111 facing inward, an electromagnetic module 114 is provided inside the sleeve 111, the movable tube 112 is arranged in the sleeve 111 and can move, a magnet is provided on one side of the movable tube 112, and the movable tube 112 is driven to move by the attraction and repulsion between the magnets toward the electromagnetic module 114, a magnetic field detector 115 is provided on the inner wall of the sleeve 111, a grinding wheel 113 driven by a motor is provided on the other side of the movable tube 112, the polishing piece is transported to the polishing component 11 through the guide rail, and the electromagnetic module 114 is used to generate the same magnetic force as the magnet on the movable tube 112 to drive The movable tube 112 drives the grinding wheel 113 to be pushed out. After contacting the polishing piece, the motor drives the grinding wheel 113 to rotate to polish the surface. At the same time, the electromagnetic module 114 is used to increase the magnetic field strength and increase the repulsive force between the magnets, so that the grinding wheel 113 generates pressure on the surface of the polishing piece to improve the polishing efficiency. The internal magnetic field strength is detected according to the magnetic field detector 115 in the sleeves 111 on both sides. The closer two magnets with the same magnetic properties are, the denser the magnetic flux lines will be, and the sparser they will be when the distance becomes farther. Through this change, the distance between the two magnets is detected to determine whether the pressures applied by the grinding wheels 113 on the polishing piece on both sides are the same, so as to avoid excessive pressure applied by the polishing component 11 on one side, resulting in too deep polishing depth on one side of the polishing piece, or causing the polishing piece to be pushed and deviated, damaging the grinding wheel 113 on the other side, so that the grinding wheels 113 on both sides can evenly apply pressure to the polishing piece for polishing.
[0020] A magnetic-resistance layer for isolating the magnetic field is provided between the movable tube 112 and the connected magnet. For example, a rubber-based composite material is used, which can not only isolate the magnetic field influence caused by the magnet on the motor and grinding wheel 113 connected to the movable tube 112, but also absorb vibration impact, thereby achieving a balance between magnetic field isolation and mechanical stability.
[0021] A water pipe 12 is provided above the polishing component 11, and nozzles 121 capable of spraying mist water droplets are arranged on the water pipe 12. When the mist water droplets are attached with dust generated by the polishing piece during the polishing process, their mass increases and they fall downward. An air suction port 102 is provided at the recessed part of the base 1, and the suction force generated can suck the mist water droplets sprayed by the nozzle 121 into it. The suction force generated by the air suction port 102 is used to suck the water droplets attached with dust into it, so as to avoid the dust combining with a large amount of water to form mud, which flows into the pores in the block, resulting in a decrease in the overall quality of the brick.
[0022] Baffles 101 are provided on both sides of the base 1. The existence of the baffles 101 can effectively prevent the diffusion of the dust and confine it within the polishing area, thereby keeping the working environment clean and reducing the impact of dust on the health of operators. Sometimes, flying fragments or particles may be generated. The baffles 101 can play a certain protective role to prevent these flying objects from directly shooting at the operators and ensure their safety.
[0023] An infrared rangefinder 13 for detecting the distance to the polished workpiece is provided next to the polishing assembly 11. The infrared rangefinder 13 can be used to detect the actual distance of the polished workpiece. By combining it with the distance data detected by the magnetic field detector 115, the real-time error can be effectively reduced. The electromagnetic module 115 can also be adjusted according to the distance data detected by the infrared rangefinder 13 to ensure that effective pressure is applied to the polished workpiece for polishing.
[0024] Working principle: The polishing piece is transported to the polishing assembly 11 through the guide rail, and the electromagnetic module 114 is used to generate the same magnetism as the magnet on the movable tube 112 for driving. The movable tube 112 drives the grinding wheel 113 to be pushed out. After contacting the polishing piece, the motor drives the grinding wheel 113 to rotate and polish the surface. At the same time, the electromagnetic module 114 is used to increase the magnetic field strength and increase the repulsive force between the magnets, so that the grinding wheel 113 generates pressure on the surface of the polishing piece, thereby improving the polishing efficiency. In addition, the magnetic field detector 115 in the sleeves 111 on both sides detects the internal magnetic field. The field strength is detected. When two magnets with the same magnetic properties are closer together, the magnetic flux lines will be denser, and when the distance becomes farther, the magnetic flux lines will become sparser. Through this change, the distance between the two magnets is detected to determine whether the pressures applied by the grinding wheels 113 on both sides to the polishing part are the same, so as to avoid excessive pressure applied by the polishing assembly 11 on one side, resulting in too deep polishing depth on one side of the polishing part, or pushing the polishing part to cause it to deviate and damage the grinding wheel 113 on the other side, so that the grinding wheels 113 on both sides can apply uniform pressure to the polishing part for polishing.
