Description

Technical Field

[0001] This utility model relates to the field of building material processing technology, and in particular to a grinding device for building steel plates. Background Technology

[0002] Steel plates are a common building material. They can be used to make building floors and platforms, which have high load-bearing capacity. Steel plate partitions offer good sound insulation, making them particularly suitable for spaces requiring a quiet environment, such as offices and conference rooms.

[0003] Before processing, steel plates need to be ground to remove the oxide layer on their surface. In the existing technology, steel plates are generally fed into a device for automatic grinding. However, the grinding device can generally only grind one side of the steel plate. After grinding one side, the steel plate needs to be flipped over and ground again. The grinding efficiency is low, and after grinding, it is found that some parts of the steel plate surface are not cleaned. This is because the parts do not make good contact with the grinding mechanism, resulting in uneven grinding. Therefore, a grinding device for building steel plates is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a grinding device for building steel plates to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a grinding device for building steel plates, including a front frame, a middle frame and a rear frame. The front frame and the rear frame are connected to the front and rear of the middle frame. A plurality of guide rollers are movably connected to the inner side of the front frame and the rear frame, and two sprockets are fixedly connected to the ends of the guide rollers. A chain is movably connected to the outer surface of the sprocket, and adjacent guide rollers are linked by the sprocket and the chain; Servo motors are installed at the bottom of the front frame and the rear frame, and the output of the servo motors drives a single guide roller to rotate via a chain. The ends of the front frame and the rear frame are fixedly connected to joints, and top rollers are movably connected between the joints. The inner side of the middle frame is movably connected to an upper grinding roller and a lower grinding roller. The ends of the upper grinding roller and the lower grinding roller are fixedly connected to two sprockets, and the outer surface of the sprockets is movably connected to a chain. A servo motor is installed at the bottom of the middle frame, and the output of the servo motor drives the lower grinding roller to rotate via a chain. A cover is fixedly connected to the top of the middle frame, and the cover covers the upper and lower grinding rollers. The top of the cover is fixedly connected to a dust suction duct, the end of the dust suction duct is fixedly connected to a filter, the filter has an integrated dust filter bag inside, and the end of the filter is fixedly connected to a fan.

[0007] Preferably, in any of the above schemes, the front frame, middle frame and rear frame are composed of an upper frame and legs connected below the frame.

[0008] The above technical solution is adopted: This device is specially used for surface grinding of building steel plates, specifically for grinding the double-sided oxide layer of the steel plate.

[0009] Preferably, in any of the above schemes, the linear array of guide rollers is located inside the front frame and the rear frame, and a total of three servo motors are deployed.

[0010] The above technical solution employs guide rollers to linearly drive the steel plate, which is then double-sided polished upon reaching the middle frame. The guide rollers are linked by sprockets and chains, and the power source is a servo motor.

[0011] Preferably, in any of the above embodiments, the top roller is located on both sides of the cover, and the top roller is located directly above the corresponding guide roller.

[0012] The core structure of this device, using the above technical solution, consists of: a middle frame, a servo motor, a connector, a top roller, an upper grinding roller, a lower grinding roller, a cover, a dust extraction duct, a filter, and a fan.

[0013] The core advantage of this device is that the steel plate is automatically driven in a straight line by several guide rollers to reach the middle frame for grinding. This is an assembly line operation, which greatly improves the grinding efficiency of batch steel plates. The steel plates can continuously enter the grinding area, reducing waiting time and improving overall work efficiency. Top rollers are installed on both sides of the middle frame. These top rollers, together with guide rollers and joints, can adjust the posture of the steel plate, pre-straighten it, and adjust the transverse and longitudinal posture of the steel plate to ensure that the steel plate is in a straight state before entering the grinding station. This pre-straightening process helps to reduce uneven grinding caused by bending or twisting of the steel plate, thereby improving grinding accuracy. At the middle frame section, an upper and lower grinding roller are movably connected to the inner side of the frame. These rollers are linked by a sprocket and chain, and are powered by servo motors. Both rollers have a frosted layer on their outer surfaces, allowing for simultaneous grinding of the oxide layer on both sides of the steel plate. This double-sided processing avoids the cumbersome process of flipping the steel plate required for traditional single-sided grinding, significantly saving time and improving grinding efficiency. It also ensures uniform force on the steel plate surface, preventing surface unevenness that can occur with single-sided grinding.

[0014] A cover is installed in the middle frame, with a dust extraction duct, filter, and fan connected sequentially above it. When the fan is working, it sucks away the grinding shavings, preventing them from leaking and polluting the air. The grinding shavings are intercepted and filtered by the filter's dust bags. The negative pressure generated by the fan draws the grinding shavings generated during grinding quickly into the system through the dust extraction duct, effectively preventing the shavings from scattering and leaking. This function is crucial for maintaining clean air in the workshop and protecting worker health.

[0015] Preferably, in any of the above embodiments, the diameters of the upper and lower grinding rollers are larger than the diameter of the guide roller, and the upper grinding roller is located directly above the lower grinding roller.

[0016] Preferably, the outer surfaces of the upper and lower grinding rollers have a frosted layer, and the dust extraction channel is bent at a 90-degree angle.

[0017] Preferably, the fan is installed horizontally, as described in any of the above schemes.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This steel plate grinding device for construction, through the coordinated arrangement of a middle frame, servo motor, joint, top roller, upper grinding roller, lower grinding roller, cover, dust extraction duct, filter, and fan, allows the steel plate to be automatically and linearly driven by several guide rollers to reach the middle frame for grinding. This is an assembly line operation, which greatly improves the grinding efficiency of batch steel plates. The steel plates can continuously enter the grinding area, reducing waiting time and improving overall work efficiency. Top rollers are installed on both sides of the middle frame. These top rollers, together with guide rollers and connectors, can adjust the posture of the steel plate, pre-straighten it, and adjust the transverse and longitudinal posture of the steel plate to ensure that the steel plate is in a straight state before entering the grinding station. This pre-straightening process helps to reduce uneven grinding caused by bending or twisting of the steel plate, thereby improving grinding accuracy.

[0019] 2. The steel plate grinding device for this building has an upper grinding roller and a lower grinding roller movably connected to the inner side of the middle frame. These rollers are linked by a sprocket and chain, and are powered by servo motors. Both rollers have a frosted layer on their outer surfaces, allowing for simultaneous grinding of the oxide layer on both sides of the steel plate. This double-sided processing avoids the cumbersome process of flipping the steel plate required for traditional single-sided grinding, significantly saving time and improving grinding efficiency. It also ensures uniform force on the steel plate surface, preventing surface unevenness that may occur with single-sided grinding.

[0020] A cover is installed in the middle frame, with a dust extraction duct, filter, and fan connected sequentially above it. When the fan is working, it sucks away the grinding shavings, preventing them from leaking and polluting the air. The grinding shavings are intercepted and filtered by the filter's dust bags. The negative pressure generated by the fan draws the grinding shavings generated during grinding quickly into the system through the dust extraction duct, effectively preventing the shavings from scattering and leaking. This function is crucial for maintaining clean air in the workshop and protecting worker health.

[0026] like Figure 1-4 As shown, the steel plate grinding device for this building includes a front frame 1, a middle frame 2 and a rear frame 3. The front frame 1 and the rear frame 3 are connected to the front and rear of the middle frame 2.

The ends of the front frame 1 and the rear frame 3 are fixedly connected to the joints 8, and the top rollers 9 are movably connected between the joints 8. The inner side of the middle frame 2 is movably connected to an upper grinding roller 10 and a lower grinding roller 11. The ends of the upper grinding roller 10 and the lower grinding roller 11 are fixedly connected to two sprockets 5, and the outer surface of the sprockets 5 is movably connected to a chain 6. A servo motor 7 is installed at the bottom of the middle frame 1. The output of the servo motor 7 drives the lower grinding roller 11 to rotate through the chain 6. A cover 12 is fixedly connected to the top of the middle frame 2, and the cover 12 covers the upper grinding roller 10 and the lower grinding roller 11. A dust extraction duct 13 is fixedly connected to the top of the cover 12, and a filter 14 is fixedly connected to the end of the dust extraction duct 13. A dust filter bag is integrated inside the filter 14, and a fan 15 is fixedly connected to the end of the filter 14.

[0027] Example 1: The front frame 1, middle frame 2, and rear frame 3 consist of an upper frame and supporting legs connected below the frame. This device is specifically designed for surface grinding of building steel plates, specifically for grinding the double-sided oxide layer of the steel plate. Guide rollers 4 are linearly arrayed inside the front frame 1 and rear frame 3, and three servo motors 7 are deployed. This device uses the guide rollers 4 to linearly drive the steel plate, and double-sided grinding is performed when the steel plate reaches the middle frame 1. The guide rollers 4 are linked together via sprockets 5 and chains 6, and the power source is the servo motors 7.

[0028] Preferably, in any of the above schemes, the top roller 9 is located on both sides of the cover 12, and the top roller 9 is located directly above the corresponding guide roller 4.

[0029] Example 2: A cover 12 is installed at the middle frame 2. Above the cover 12, a dust extraction duct 13, a filter 14, and a fan 15 are connected in sequence. When the fan 15 is working, it can suck up the grinding debris, preventing it from leaking and polluting the air. The grinding debris is intercepted and filtered by the filter bag of the filter 14. The diameters of the upper grinding roller 10 and the lower grinding roller 11 are larger than the diameter of the guide roller 4, and the upper grinding roller 10 is located directly above the lower grinding roller 11. The outer surfaces of the upper grinding roller 10 and the lower grinding roller 11 have a frosted layer. The dust extraction duct 13 is bent at a 90-degree angle.

[0030] The working principle of this utility model is as follows: The steel plate is linearly driven by guide rollers 4, and double-sided grinding is performed when the steel plate reaches the middle frame 1. The guide rollers 4 are linked by sprockets 5 and chains 6, and the power source is a servo motor 7; On both sides of the middle frame 2, top rollers 9 are set. The top rollers 9, together with guide rollers 4 and joints 8, can adjust the posture of the steel plate, pre-straighten it, adjust the transverse and longitudinal posture of the steel plate, and ensure that the steel plate is in a straight state before entering the grinding station. When the steel plate passes between the upper grinding roller 10 and the lower grinding roller 11, the upper grinding roller 10 and the lower grinding roller 11 are linked by the sprocket 5 and the chain 6. The power source of the upper grinding roller 10 and the lower grinding roller 11 is a servo motor. The outer surfaces of the upper grinding roller 10 and the lower grinding roller 11 are both covered with a frosted layer. When they rotate at high speed, they can simultaneously grind the oxide layer on the front and back of the steel plate. At the middle frame 2, a cover 12 is installed. The dust suction channel 13, the filter 14 and the fan 15 are connected in sequence above the cover 12. When the fan 15 is working, it can suck away the grinding debris to prevent the grinding debris from leaking out and polluting the air. The grinding debris is intercepted and filtered by the dust filter bag of the filter 14. The negative pressure generated when the fan 15 is working will quickly suck the grinding debris generated during the grinding process into the system through the dust suction channel 13. The polished steel plate enters the rear frame 3 for output.

[0031] Compared with the prior art, the present invention has the following advantages: 1. The steel plate grinding device for buildings is configured with a middle frame 2, servo motor 7, connector 8, top roller 9, upper grinding roller 10, lower grinding roller 11, cover 12, dust suction duct 13, filter 14, and fan 15. The steel plate is automatically and linearly driven by several guide rollers 4 to the middle frame 2 for grinding. It is an assembly line operation, which greatly improves the grinding efficiency of batch steel plates. The steel plates can continuously enter the grinding area, reducing waiting time and improving the overall operation efficiency. On both sides of the middle frame 2, top rollers 9 are installed. The top rollers 9, together with guide rollers 4 and connectors 8, can adjust the posture of the steel plate and pre-straighten it, adjusting the transverse and longitudinal posture of the steel plate to ensure that the steel plate is in a straight state before entering the grinding station. This pre-straightening process helps to reduce the problem of uneven grinding caused by bending or twisting of the steel plate, thereby improving the grinding accuracy.

[0032] 2. The steel plate grinding device for this building has an upper grinding roller 10 and a lower grinding roller 11 movably connected to the inner side of the middle frame 2. The upper grinding roller 10 and the lower grinding roller 11 are linked by a sprocket 5 and a chain 6. The power source for the upper grinding roller 10 and the lower grinding roller 11 is a servo motor. The outer surfaces of the upper grinding roller 10 and the lower grinding roller 11 are both covered with a frosted layer, which can simultaneously grind the oxide layer on both sides of the steel plate, providing double-sided treatment. This avoids the cumbersome process of flipping the steel plate required for traditional single-sided grinding, thus greatly saving time and improving grinding efficiency. It ensures that the surface of the steel plate is subjected to uniform force, avoiding the surface unevenness that may occur during single-sided grinding.

[0033] At two points along the middle frame, covers 12 are installed. Above the covers 12, a dust extraction duct 13, a filter 14, and a fan 15 are connected in sequence. When the fan 15 is working, it can suck away the grinding debris, preventing it from leaking out and polluting the air. The grinding debris is intercepted and filtered by the dust filter bag of the filter 14. The negative pressure generated when the fan 15 is working quickly draws the grinding debris generated during the grinding process into the system through the dust extraction duct 13, effectively preventing the grinding debris from scattering and leaking out. This function is crucial for maintaining clean air in the workshop and protecting the health of workers.
