Description

Technical Field

[0001] This invention belongs to the field of production equipment technology, and in particular relates to a steel plate grinding brush device. Background Technology

[0002] Steel plate grinding devices are used to remove oxides or other impurities from the upper and lower surfaces of steel plates. During the grinding process, water needs to be continuously sprayed onto the brush wheel through a water spray pipe. However, because the brush wheel moves axially and rotates axially during operation and moves up and down when stopped, its special movement makes it difficult for the sealing structure to meet its sealing requirements. Currently, HPE material blocks that can move up and down are often used, and sealing is achieved by controlling the gap between the block hole and the shaft. However, as the working time increases, the HPE material blocks are prone to wear, and the gap increases, leading to increasingly serious water leakage from the grinding device, which not only affects the production environment. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a steel plate grinding brush device that can ensure the sealing of the grinding brush device while meeting the movement requirements of the brush wheel during operation, thereby preventing water leakage, which would affect the production environment and slow down the production progress.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A steel plate grinding device includes a housing, within which multiple rollers are disposed. The housing has multiple openings through which the rollers pass. A sealing assembly is installed on each opening. The sealing assembly includes a first water-blocking member disposed on the opening and a retaining ring sleeved on the roller. The retaining ring is located within the housing and also has a limiting groove. The first water-blocking member has a through hole. A second water-blocking member is further disposed between the first water-blocking member and the roller, sleeved on the roller. One end of the second water-blocking member is movably disposed within the limiting groove, and the other end has a protruding limiting portion located on the side of the first water-blocking member away from the retaining ring. The size of the limiting portion is larger than the size of the through hole. A gap exists between the second water-blocking member and the first water-blocking member.

[0006] In one embodiment, a plurality of rollers are distributed on the upper and lower sides of the steel plate to be brushed. Each roller has a plurality of sequentially arranged rubber-coated rollers and a brush wheel with the rubber-coated rollers flush with each other. The brush wheel is located between two adjacent rubber-coated rollers. In this embodiment, the rubber-coated rollers are used to transport the steel plate, while the brush wheel is used to clean oxides and impurities on the steel plate.

[0007] In one embodiment, the housing is further provided with a plurality of first water spray pipes located between two adjacent rubber-coated rollers. The nozzles of the first water spray pipes are all directed toward the brush wheel in the other roller. A second water spray pipe is also provided on the side of the housing near the steel plate inlet end. The second water spray pipe is located at the top of the housing and extends in a bend toward the brush wheel. The nozzles of the second water spray pipe are directed toward the gap between the brush wheel and the rubber-coated roller. In this embodiment, the first water spray pipes provided in this embodiment can spray and brush the steel plate when the steel plate passes by and spray and brush the brush wheel when no steel plate passes by, forming a dual-purpose pipe, effectively saving the number of water spray pipes, and preventing the steel plate from carrying slag into the device of the next process. The second water spray pipes can spray the steel plate that has just entered the device. The second water spray pipes extend in a bend toward the brush wheel, which not only prevents the steel plate from being in a dry grinding state when entering the device, but also prevents water from leaking out from the inlet of the grinding device.

[0008] In one embodiment, a baffle plate is further provided between the side wall of the housing and the second water spray pipe. In this embodiment, the baffle plate further prevents water from leaking out from the inlet of the brush device.

[0009] In one embodiment, a recessed settling portion is provided on the bottom of the housing near the outlet end of the steel plate. The settling portion corresponds to the position of the brush wheel located on the lower side of the steel plate. In this embodiment, due to the increasing compactness of the device and the continuous operation of the water spray pipe inside the brushing device, water is prone to accumulate inside the device. This causes the brush wheel located on the lower side of the steel plate to be immersed in water for a long time, which can easily lead to the failure of the dynamic balance of the device and damage to the brush wheel. In this embodiment, a recessed settling portion is provided inside the device so that the water inside the device settles in the settling portion, increasing the distance between the brush wheel and the water surface and preventing the brush wheel from being immersed in water.

[0010] In one embodiment, the settling section includes a first settling trough recessed at the bottom of the housing, and a second settling trough is also staggered at the bottom of the first settling trough. One end of the second settling trough is connected to the first settling trough, and the other end is connected to the return water tank. In this embodiment, the staggered first and second settling troughs accelerate the return flow of sprayed water, increase the volume that can be deposited, and further prevent the brush wheel from being immersed in water.

[0011] In one embodiment, a protruding frame is further provided on the side wall of the housing, and a connecting bearing that mates with the rubber-coated wheel is mounted on the frame. There is a gap between the connecting bearing and the side wall of the housing. In this embodiment, by setting a frame on the side wall of the housing and fixing the connecting bearing on the frame instead of the traditional method of directly mounting the connecting bearing on the side wall, the surface area to be machined for the connecting bearing is greatly reduced, the load-bearing pressure on the housing is reduced, and the installation of the rubber-coated wheel is more convenient and quick. At the same time, the gap between the housing and the connecting bearing can effectively prevent leaked water from entering the connecting bearing, thereby improving the service life of the connecting bearing.

[0012] In one embodiment, the side wall of the housing has a brush inlet for a steel plate to enter and exit. A guide assembly fixed to the side wall of the housing is provided at the brush inlet for the steel plate to enter. The guide assembly includes a guide shaft mounted on a bearing and multiple guide wheels mounted on the guide shaft. In this embodiment, the multiple guide wheels on the guide assembly can assist the steel plate to enter the brushing device for brushing and guide it.

[0013] In one embodiment, the bearing is fixed to the side wall of the housing by a mounting base. The bearing is located at the end of the brush inlet. The bearing is also provided with a cap for sealing the guide shaft. The bearing is made of stainless steel. By placing the bearing at the end of the brush inlet in this embodiment, water that occasionally spills from the housing can be prevented from corroding the bearing. At the same time, the bearing is made of stainless steel and the end of the bearing is sealed by the cap to further prevent it from rusting.

[0014] In one embodiment, a drive assembly is connected to the end of the brush wheel located outside the housing. A lifting assembly is also installed at the bottom of the drive assembly. The lifting assembly is fixed to the frame of the housing via a connector. The connector includes multiple arc-shaped ribs. One end of each rib is connected to the lifting assembly, and the other end is connected to a fixing plate. The frame has a positioning groove corresponding to the size of the fixing plate. In this embodiment, the drive assembly drives the brush wheel to rotate axially, while the lifting assembly is used to move the brush wheel up and down. The lifting assembly is directly fixed to the frame via the connector. Compared with the fixing method using bolts, this improves the stability and vibration resistance of the brush wheel and even the entire brushing device, increases rigidity, reduces the number of parts, and saves costs. At the same time, the positioning groove on the frame corresponding to the size of the fixing plate improves the installation accuracy of the lifting assembly and shortens the installation time of the lifting assembly.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) The labyrinth-type sealing components not only meet the motion requirements of the brush wheel during operation, but also ensure the sealing of the brush device.

[0017] (2) The water spray pipe inside the shell is improved. The first water spray pipe can spray the steel plate when the steel plate passes by and spray the brush wheel when no steel plate passes by, forming a dual-purpose pipe, which effectively saves the number of water spray pipes and prevents the steel plate from carrying slag into the device of the next process. The second water spray pipe can spray the steel plate that has just entered the device, and the second water spray pipe bends and extends towards the brush wheel, which not only prevents the steel plate from being dry-grinding when entering the device, but also prevents water from leaking out from the inlet of the brush device.

[0018] (3) The lifting assembly is fixed to the frame by connectors instead of the traditional bolt fixing method, which improves the stability and vibration resistance of the brush wheel and even the entire brush device, increases rigidity, reduces the number of parts, and saves costs. At the same time, the frame has positioning slots that correspond to the size of the fixing plate, which improves the installation accuracy of the lifting assembly and shortens the installation time of the lifting assembly.

Detailed Implementation

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] This invention provides a steel plate grinding brush device, such as... Figure 1 , Figure 2 as well as Figure 3 As shown, the device includes a housing 1, inside which are multiple rollers 2. The housing 1 has multiple openings through which the rollers 2 pass. A sealing assembly 3 is installed on the openings of the housing 1. The sealing assembly 3 includes a first water-blocking member 301 disposed on the opening and a fixing ring 302 sleeved on the rollers 2. The fixing ring 302 is located inside the housing 1 and also has a limiting groove 3011. The first water-blocking member 301 has a through hole. A second water-blocking member 303 is disposed between the first water-blocking member 301 and the rollers 2 and is sleeved on the rollers 2. One end of the second water-blocking member 303 is movably disposed in the limiting groove 3011, and the other end has a protruding limiting part 3031. The limiting part 3031 is located on the side of the first water-blocking member 301 away from the fixing ring 302, and the size of the limiting part 3031 is larger than the size of the through hole. There is a movable gap between the second water-blocking member 303 and the first water-blocking member 301.

[0032] Specifically, such as Figure 4 As shown, multiple rollers 2 are distributed on the upper and lower sides of the steel plate to be brushed. Each roller 2 has multiple rubber-coated rollers 201 arranged in sequence and brush rollers 202 arranged flush with the rubber-coated rollers 201. The brush rollers 202 are located between two adjacent rubber-coated rollers 201. The rubber-coated rollers 201 in the roller 2 are used to transport the steel plate, while the brush rollers 202 are used to clean oxides and impurities on the steel plate.

[0033] It should be noted that since the brush wheel 202 moves and rotates axially during operation and moves up and down when stopped, its special movement makes it difficult for conventional sealing structures to meet its sealing requirements. Currently, HPE material baffles that can move up and down are often used, and sealing is achieved by controlling the gap between the baffle hole and the shaft. However, as the working time increases, the HPE material baffles are prone to wear, and the gap increases, resulting in more and more serious water leakage in the brush device. This not only affects the production environment but may also cause safety accidents. In this embodiment, the fixed ring 302, the first water baffle 301 and the second water baffle 303 together form a labyrinth-type sealing structure. The gap between the second water baffle 303, the first water baffle 301 and the fixed ring 302 meets the movement requirements of the brush wheel 202, while preventing water inside the housing 1 from leaking to the outside of the housing 1.

[0034] In one embodiment, such as Figure 4 and Figure 5 As shown, the housing 1 is also provided with a plurality of first water spray pipes 9 located between two adjacent rubber-coated rollers 201. The nozzles of the first water spray pipes 9 are all directed toward the brush roller 202 in the other roller 2. The housing 1 is also provided with a second water spray pipe 10 on the side near the steel plate inlet end. The second water spray pipe 10 is located at the top of the housing 1. The second water spray pipe 10 bends and extends toward the brush roller 202, and the nozzle of the second water spray pipe 10 is directed toward the gap between the brush roller 202 and the rubber-coated roller 201.

[0035] It should be noted that by designing the installation position of the water spray pipe inside the housing 1 and the orientation of the nozzle of the water spray pipe, not only is the cost reduced, but the spraying effect is also provided. That is, the first water spray pipe 9 can spray and brush the steel plate when the steel plate passes by, and spray and brush the brush wheel 202 when no steel plate passes by, forming a dual-purpose pipe, effectively saving the number of water spray pipes, and at the same time preventing the steel plate from carrying slag into the device of the next process. The second water spray pipe 10 can spray the steel plate that has just entered the device, and the second water spray pipe 10 bends and extends towards the brush wheel 202, which not only prevents the steel plate from being in a dry grinding state when entering the device, but also prevents water from leaking out from the inlet of the grinding brush device.

[0036] Furthermore, such as Figure 4 As shown, a baffle plate 11 is also provided between the side wall of the housing 1 and the second water spray pipe 10. One end of the baffle plate 11 is installed on the side wall of the housing 1, and the other end extends toward the second water spray pipe 10. That is, the baffle plate 11 further prevents water from leaking out from the inlet of the brush device.

[0037] In one embodiment, such as Figure 5 As shown, a recessed settling part 12 is provided on the bottom side of the housing 1 near the steel plate outlet end, and the settling part 12 corresponds to the position of the brush wheel 202 located on the lower side of the steel plate.

[0038] Specifically, the settling section 12 includes a first settling water tank 1201 recessed at the bottom of the shell 1. A second settling water tank 1202 is also alternately arranged at the bottom of the first settling water tank 1201. One end of the second settling water tank 1202 is connected to the first settling water tank 1201, and the other end is connected to the return water tank.

[0039] It should be noted that during the design process, the compactness requirements of the grinding brush device are becoming increasingly stringent. However, due to the continuous operation of the water spray pipe inside the grinding brush device, water accumulation is likely to occur inside the device. This causes the brush wheel 202 located on the underside of the steel plate to be immersed in water for a long time, which can easily lead to the failure of the dynamic balance of the device and damage to the brush wheel 202. In this embodiment, a recessed settling part 12 is provided inside the device, so that the water inside the device settles in the settling part 12, increasing the distance between the brush wheel 202 and the water surface and preventing the brush wheel 202 from being immersed in water. At the same time, the staggered arrangement of the first settling water tank 1201 and the second settling water tank 1202 accelerates the backflow of the sprayed water and increases the volume that can be deposited, further preventing the brush wheel 202 from being immersed in water.

[0040] In one embodiment, such as Figure 1 , Figure 2 as well as Figure 6 As shown, a protruding frame 4 is also provided on the side wall of the housing 1. A connecting bearing 5 that cooperates with the rubber-coated wheel 201 is installed on the frame 4. There is a gap between the connecting bearing 5 and the side wall of the housing 1.

[0041] It should be noted that in conventional grinding devices, the connecting bearing 5 is directly fixed to the side wall of the housing and connected to the rubber-coated wheel 201. However, due to the large size of the housing 1, and considering economic costs, the housing 1 itself is not precision-machined. This results in unevenness when the connecting bearing 5 is installed on the side wall of the housing 1. Furthermore, due to the large number of connecting bearings 5, the overall precision difference after installation is significant, which not only affects the operating accuracy of the entire grinding device but also increases the assembly time. In this embodiment, a protruding frame 4 is provided on the side wall of the housing 1. The connecting bearing 5 is fixed on the frame 4 instead of the traditional method of directly installing the connecting bearing 5 on the side wall. Precision machining is only performed on the mounting surface of the connecting bearing 5, which greatly reduces the required machining area and improves the operating accuracy of the device. At the same time, compared with the traditional installation method, the installation structure of this embodiment also reduces the load-bearing pressure of the entire housing 1 and makes it more convenient and faster to install the rubber-coated wheel 201. In addition, there is a gap between the housing 1 and the connecting bearing 5, which can effectively prevent leaked water from entering the connecting bearing 5 and improve the service life of the connecting bearing 5.

[0042] In one embodiment, such as Figure 1As shown, the side wall of the housing 1 has a brush inlet 6 for the steel plate to enter and exit. A guide assembly fixed to the side wall of the housing 1 is provided at the brush inlet 6 for the steel plate to enter. The guide assembly includes a guide shaft 7 mounted on a bearing 8. Multiple guide wheels are mounted on the guide shaft 7. That is, the multiple guide wheels on the guide assembly can assist the steel plate to enter the brushing device for brushing and guide it.

[0043] Specifically, the bearing 8 is fixed to the side wall of the housing 1 by a mounting base. The bearing 8 is located at the end of the brush port 6. The bearing 8 is also provided with a pressure cap for sealing the guide shaft 7. The bearing 8 is made of stainless steel.

[0044] It should be noted that, as Figure 1 As shown, the bearing 8 is placed at the end of the brush port 6 to prevent water that occasionally spills from the housing 1 from corroding the bearing 8. At the same time, the bearing 8 is made of stainless steel and the end of the bearing 8 is sealed by a cap to further prevent it from rusting.

[0045] In one embodiment, such as Figure 1 and Figure 7 As shown, the brush wheel 202 is connected to the drive assembly 13 at the end outside the housing 1. The bottom of the drive assembly 13 is also equipped with a lifting assembly 14. The lifting assembly 14 is fixed to the frame 4 of the housing 1 by a connector. The connector includes multiple arc-shaped ribs 15. One end of the rib 15 is connected to the lifting assembly 14, and the other end is connected to a fixing plate 16. The frame 4 is provided with a positioning groove 401 corresponding to the size of the fixing plate 16.

[0046] It should be noted that the drive component 13 drives the brush wheel 202 to rotate axially, while the lifting component 14 is used to move the brush wheel 202 up and down. In traditional brush grinding devices, the lifting component 14 is fixed to the base of the housing 1 by bolt connection, which can easily cause instability and vibration of the entire brush wheel 202. The shaking is more obvious when the dynamic balance fails, which not only increases the noise. In this embodiment, the lifting component 14 is directly fixed to the frame 4 by a connector. Compared with the bolt connection, this not only improves the stability and vibration resistance of the brush wheel 202 and even the entire brush grinding device, but also increases rigidity and reduces the number of parts, saving costs. At the same time, the frame 4 has a positioning groove 401 that corresponds to the size of the fixing plate 16, which improves the installation accuracy of the lifting component 14 and shortens the installation time of the lifting component 14.

[0047] In one embodiment, the lifting components 14 located on both sides of the housing are connected by a synchronous shaft set at the bottom of the housing. One end of the synchronous shaft is connected to the lifting component 14 through a flange coupling, and the other end is connected to the lifting component 14 through a keyless bearing. This ensures that after the lifting component 14 is leveled, the connection and installation are not affected regardless of the magnitude of the deflection angle change, thereby improving assembly efficiency and effectively solving installation design defects.
