Description

Technical Field

[0001] This invention belongs to the field of production equipment technology, and in particular relates to a brush washing and drying machine. Background Technology

[0002] The steel plate passes through a series of processes, including grinding, washing, and drying, from the inlet of the grinding and washing dryer to clean its surface for subsequent PCB board manufacturing. During the grinding process, to prevent dry grinding, the steel plate needs to be continuously sprayed with water. During the washing process, the high-pressure water spray pipe in the washing assembly continuously rinses the steel plate. Therefore, the sealing of the grinding and washing dryer is crucial. Otherwise, it will not only waste water resources but also easily affect the production environment and production progress. However, because the brush wheels in the grinding assembly and the water squeezing wheels in the washing assembly move and rotate axially during operation and move up and down when the machine stops, their special movements make it difficult for traditional sealing structures to meet their sealing requirements. Moreover, as the working time increases, the water leakage problem of the grinding and washing dryer becomes more and more serious. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art by providing a brush washing and drying machine that not only meets the movement requirements of the brush wheel and the squeezing wheel, but also ensures the sealing effect of the device and has a long sealing life.

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

[0005] A brush washing and drying machine includes a brush assembly, a washing assembly, and a drying assembly arranged sequentially along the moving direction of a steel plate. The washing assembly includes a housing and a squeezing wheel penetrating the housing. An opening is provided on the side wall of the housing for the squeezing wheel to pass through. A sealing assembly is provided on the opening. The sealing assembly includes a first water-blocking member disposed on the opening and a fixing ring sleeved on the squeezing wheel. The fixing ring is located inside the housing and has a limiting groove. A through hole is provided on the first water-blocking member. A second water-blocking member sleeved on the squeezing wheel is also disposed between the first water-blocking member and the through hole. One end of the second water-blocking member is movably disposed in the limiting groove, and the other end has a protruding limiting part. The limiting part is located on the side of the first water-blocking member away from the fixing ring, and the size of the limiting part is larger than the size of the through hole. There is an movable gap between the second water-blocking member and the first water-blocking member. A plurality of rollers are disposed inside the brush assembly, and the rollers are connected to the housing of the brush assembly through the sealing assembly.

[0006] In one embodiment, a lifting assembly for replacing the brush wheel is provided on one side of the brush assembly. The cantilever of the lifting assembly is located above the brush assembly and a movable hand chain hoist is installed on it. A water tank is installed on the other side of the brush assembly. Both the brush assembly and the washing assembly are connected to the water tank. Pumps communicating with the water tank are provided on both sides of the water tank. In this embodiment, the lifting assembly facilitates the replacement of the brush wheel of the brush assembly, and the pumps are directly installed on the water tank, which not only saves space but also reduces the piping between the water tank and the pumps.

[0007] In one embodiment, the portion of the squeezing wheel protruding from the housing and the portion of the roller protruding from the outer shell are both connected to a connecting bearing. The bottom of the connecting bearing is fixed to the frame of the housing, and there is a gap between the connecting bearing and the housing. In this embodiment, fixing the connecting bearing to the frame instead of the traditional method of directly mounting the connecting bearing to the housing not only significantly reduces the surface area to be machined for the connecting bearing but also reduces the load-bearing pressure on the entire outer shell of the brush washing dryer. It is also more convenient and faster to install the squeezing wheel and the roller. At the same time, the gap between the outer shell of the brush washing dryer and the connecting bearing effectively prevents leaked water from entering the connecting bearing, thereby improving the service life of the connecting bearing.

[0008] In one embodiment, the drying assembly is provided with a plurality of air blades located on the upper and lower sides of the steel plate. The two ends of each air blade are connected to an adjustment seat that penetrates the housing of the drying assembly. The adjustment seat is located outside the housing of the drying assembly and has a connecting rod that penetrates the housing of the drying assembly. The connecting rod is connected to the end of the air blade. In this embodiment, the air blades are used to dry the water on the steel plate. The adjustment seats at both ends of the air blades can adjust the position and angle of the air blades according to the actual situation. At the same time, the adjustment seats are located outside the housing of the drying assembly, which makes it convenient for the operator to adjust the position and angle of the air blades manually at any time.

[0009] In one embodiment, the drying assembly further includes a pressing wheel located on the upper side of the steel plate and a transport wheel located on the lower side of the steel plate. The transport wheel is connected to a drive device, and the transport wheel and the pressing wheel are meshed by gears. In this embodiment, the steel plate is transported by the transport wheel and the pressing wheel. The meshing gear between the transport wheel and the pressing wheel causes the pressing wheel and the transport wheel to rotate together, giving the pressing wheel a transporting power as well. This prevents the steel plate from jumping during transport, which could cause relative sliding between the steel plate and the pressing wheel and scratch the steel plate.

[0010] In one embodiment, a plurality of rollers are distributed on the upper and lower sides of the steel plate to be brushed. Each roller on each side 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. The housing also contains 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 on the other side of the roller. A second water spray pipe is also provided on the side of the housing near the inlet end of the steel plate. The second water spray pipe is located at the top of the housing and bends toward the brush wheel. The second water spray pipe is bent and extended, and the nozzle of the second water spray pipe faces the gap between the brush wheel and the rubber-coated wheel. In this embodiment, 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, 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 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 grinding brush device.

[0011] 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.

[0012] In one embodiment, a recessed settling portion is provided on the bottom of the outer casing 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.

[0013] In one embodiment, the settling section includes a first settling trough recessed at the bottom of the outer casing. 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.

[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 movement requirements of the rollers and water-squeezing wheels during operation, but also ensure the sealing effect of the device and have a long sealing life.

[0017] (2) A frame is set on the side wall of the housing of the washing component. By fixing the connecting bearing on the frame, the surface area of ​​the connecting bearing is significantly reduced, the bearing pressure of the housing is reduced, and the installation of the water squeezing wheel is more convenient and quick. At the same time, there is a gap between the housing and the connecting bearing, which can effectively prevent leaked water from entering the connecting bearing and improve the service life of the connecting bearing.

[0018] (3) Improve the water spray pipe inside the shell. 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.

[0019] (4) 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

[0034] The invention will now be further described with reference to the accompanying drawings.

[0035] This invention provides a brush washing and drying machine, such as Figures 1 to 4 As shown, the assembly includes a brush assembly 1, a washing assembly 2, and a drying assembly 3 arranged sequentially along the moving direction of the steel plate. The washing assembly 2 includes a housing and a water-squeezing wheel 8 penetrating the housing. An opening is provided on the side wall of the housing for the water-squeezing wheel 8 to pass through. A sealing assembly 7 is provided on the opening. The sealing assembly 7 includes a first water-blocking member 702 provided on the opening and a fixing ring 701 sleeved on the water-squeezing wheel 8. The fixing ring 701 is located inside the housing and has a limiting groove 7011. A through hole is provided on the first water-blocking member 702. A second water-blocking component 703 is also provided between the 02 and the through hole and is sleeved on the water-squeezing wheel 8. One end of the second water-blocking component 703 is movably disposed in the limiting groove 7011, and the other end has a protruding limiting part 7031. The limiting part 7031 is located on the side of the first water-blocking component 702 away from the fixing ring 701, and the size of the limiting part 7031 is larger than the size of the through hole. There is an movable gap between the second water-blocking component 703 and the first water-blocking component 702. Multiple rollers are provided in the brush assembly 1, and the rollers are connected to the outer shell of the brush assembly 1 through the sealing component 7.

[0036] Specifically, multiple rollers are distributed on the upper and lower sides of the steel plate to be polished. Each roller has multiple rubber-coated rollers 16 arranged in sequence and brush rollers 17 arranged flush with the rubber-coated rollers 16. The brush rollers 17 are located between two adjacent rubber-coated rollers 16. The rubber-coated rollers 16 in the rollers are used to transport the steel plate, while the brush rollers 17 are used to clean oxides and impurities on the steel plate. The brush rollers 17 and rubber-coated rollers 16 in the polishing assembly 1 are connected to the outer shell of the polishing assembly 1 through the sealing assembly 7.

[0037] It should be noted that because the brush wheel 17 and the squeezing wheel 8 move and rotate axially during operation and move up and down when stopped, their special movements make it difficult for conventional sealing structures to meet their sealing requirements. The brush wheel 17 in the brush assembly 1 often uses HPE material and a movable stop block, relying on controlling the gap between the stop block hole and the shaft to achieve sealing. The squeezing wheel 8 in the washing assembly 2 often uses an oil seal and an O-ring for sealing, but with the increase of working time, the HPE material stop block is prone to wear. As the gap increases, the oil seal and O-ring are also prone to aging and failure, resulting in increasingly serious water leakage in the brush assembly 1. This not only affects the production environment but may also cause safety accidents. In this embodiment, the fixed ring 701, the first water baffle 702 and the second water baffle 703 together form a labyrinth-type sealing structure. The gap between the second water baffle 703, the first water baffle 702 and the fixed ring 701 meets the movement requirements of the brush wheel 17 and the squeezing wheel 8, while ensuring the sealing performance of the brush washing and drying machine and having a long sealing life.

[0038] In one embodiment, such as Figure 1 As shown, a hoisting assembly 4 for replacing the brush wheel 17 is also provided on one side of the brush assembly 1. The cantilever of the hoisting assembly 4 is located above the brush assembly 1, and a movable hand chain hoist is installed on it. A water tank 5 is also installed on the other side of the brush assembly 1. Both the brush assembly 1 and the washing assembly 2 are connected to the water tank 5. Pumps 6 connected to the water tank 5 are also provided on both sides of the water tank 5. That is, the hoisting assembly 4 facilitates the replacement of the brush wheel 17 of the brush assembly 1. In traditional brush washing and drying machines, the pump 6 is set separately, which not only occupies a lot of space, but also requires a lot of piping between the pump 6 and the water tank 5. However, in this embodiment, the pump 6 is directly installed on the water tank 5, which not only saves space, but also reduces the piping between the water tank 5 and the pump 6.

[0039] In one embodiment, the portion of the water-squeezing wheel 8 protruding from the housing and the portion of the roller protruding from the housing are both connected to the connecting bearing 9. The bottom of the connecting bearing 9 is fixed to the frame 12 of the housing, and there is a gap between the connecting bearing 9 and the housing.

[0040] It should be noted that in conventional brush assembly 1 and washing assembly 2, the connecting bearing 9 is directly fixed to the side wall and then connected to the rubber-coated wheel 16 and the squeezing wheel 8. However, due to the large volume of the entire brush washing and drying machine shell, and considering economic costs, the shell itself is not precision-machined. This results in unevenness when the connecting bearing 9 is installed on the shell. Furthermore, due to the large number of connecting bearings 9, the overall precision difference after installation is significant, which not only affects the operating accuracy of the entire brush washing and drying machine but also increases the assembly time of the device. In this embodiment, a protruding frame 1 is provided on the side wall of the shell. 2. By fixing the connecting bearing 9 on the frame 12 instead of the traditional method of directly mounting the connecting bearing 9 on the side wall, the machining is only performed on the mounting surface of the connecting bearing 9, 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 grinding brush washing dryer shell. It is also more convenient and quick to install the water squeezing wheel 8 and rollers. In addition, there is a gap between the grinding brush washing dryer shell and the connecting bearing 9, which can effectively prevent leaked water from entering the connecting bearing 9 and improve the service life of the connecting bearing 9.

[0041] In one embodiment, such as Figure 5 As shown, the drying assembly 3 is equipped with multiple air blades 10 located on the upper and lower sides of the steel plate. The two ends of the air blades 10 are connected to adjustment seats 11 that penetrate the shell of the drying assembly 3. The adjustment seats 11 are located on the outside of the shell of the drying assembly 3 and have connecting rods that penetrate the shell of the drying assembly 3. The connecting rods are connected to the ends of the air blades 10. That is, the air blades 10 are used to dry the water on the steel plate. The adjustment seats 11 at both ends of the air blades 10 can adjust the position and angle of the air blades 10 according to the actual situation. At the same time, the adjustment seats 11 are located on the outside of the shell of the drying assembly 3 so that the operator can adjust the position and angle of the air blades 10 manually at any time.

[0042] Furthermore, such as Figure 6 As shown, the drying assembly 3 is also equipped with a pressing wheel 13 located on the upper side of the steel plate and a transport wheel 14 located on the lower side of the steel plate. The transport wheel 14 is connected to a drive device, and the transport wheel 14 and the pressing wheel 13 are meshed by a gear 15. The steel plate is transported by the transport wheel 14 and the pressing wheel 13. The meshing gear 15 between the transport wheel 14 and the pressing wheel 13 causes the pressing wheel 13 and the transport wheel 14 to rotate together, so that the pressing wheel 13 also has a conveying power, avoiding jumping during the transport of the steel plate, which would cause relative sliding between the steel plate and the pressing wheel 13 and scratch the steel plate.

[0043] In one embodiment, such as Figure 8As shown, the housing of the brush assembly 1 is also provided with a plurality of first water spray pipes 18 located between two adjacent rubber-coated rollers 16. The nozzles of the first water spray pipes 18 are all directed toward the brush wheel 17 in the other roller. A second water spray pipe 19 is also provided on the side of the housing near the steel plate inlet end. The second water spray pipe 19 is located at the top of the housing. The second water spray pipe 19 bends and extends toward the brush wheel 17, and the nozzle of the second water spray pipe 19 is directed toward the gap between the brush wheel 17 and the rubber-coated roller 16.

[0044] It should be noted that by designing the installation position of the water spray pipe inside the housing and the direction 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 18 can spray and brush the steel plate when the steel plate passes by, and spray and brush the brush wheel 17 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 19 can spray the steel plate that has just entered the device, and the second water spray pipe 19 bends and extends towards the brush wheel 17, 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.

[0045] Furthermore, such as Figure 8 As shown, a baffle plate 20 is also provided between the side wall of the housing and the second water spray pipe 19. One end of the baffle plate 20 is installed on the side wall of the housing, and the other end extends toward the second water spray pipe 19. That is, the baffle plate 20 further prevents water from leaking out from the inlet of the brush device.

[0046] In one embodiment, such as Figure 9 As shown, a recessed settling part 21 is provided on the side of the bottom of the shell near the steel plate outlet end, and the settling part 21 corresponds to the position of the brush wheel 17 located on the lower side of the steel plate.

[0047] Specifically, the settling section 21 includes a first settling trough 2101 recessed at the bottom of the shell, and a second settling trough 2102 is also alternately arranged at the bottom of the first settling trough 2101. One end of the second settling trough 2102 is connected to the first settling trough 2101, and the other end is connected to the return water tank 5.

[0048] It should be noted that during the design process, the compactness requirements of the brush assembly 1 are becoming increasingly stringent. However, due to the continuous operation of the water spray pipe inside the brush device, water is prone to accumulate inside the device. This causes the brush wheel 17 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 17. In this embodiment, a recessed settling part 21 is provided inside the device so that the water inside the device can be deposited in the settling part 21, increasing the distance between the brush wheel 17 and the water surface and preventing the brush wheel 17 from being immersed in water. At the same time, the staggered first settling water tank 2101 and second settling water tank 2102 accelerate the backflow of the sprayed water and increase the volume that can be deposited, further preventing the brush wheel 17 from being immersed in water.

[0049] In one embodiment, such as Figure 7 As shown, the housing of the grinding brush assembly 1 has a grinding brush port 24 for the steel plate to enter and exit. A guide assembly fixed on the housing is provided at the grinding brush port 24 for the steel plate to enter. The guide assembly includes a guide shaft 25 mounted on a bearing 26. Multiple guide wheels are mounted on the guide shaft 25. That is, the multiple guide wheels on the guide assembly can assist the steel plate to enter the grinding brush device for grinding and guide it.

[0050] Specifically, the bearing 26 is fixed to the side wall of the housing by a mounting base. The bearing 26 is located at the end of the brush port 24. The bearing 26 is also provided with a pressure cap for sealing the guide shaft 25. The bearing 26 is made of stainless steel.

[0051] It should be noted that, as Figure 7 As shown, the bearing 26 is placed at the end of the brush port 24 to prevent water that occasionally spills from the housing from corroding the bearing 26. At the same time, the bearing 26 is made of stainless steel and the end of the bearing 26 is sealed by a cap to further prevent it from rusting.

[0052] In one embodiment, such as Figure 7 and Figure 10 As shown, the brush wheel 17 is connected to a drive assembly 23 at the end outside the housing. A lifting assembly 22 is also installed at the bottom of the drive assembly 23. The lifting assembly 22 is fixed to the frame 12 of the housing by a connector. The connector includes multiple arc-shaped ribs 27. One end of the rib 27 is connected to the lifting assembly 22, and the other end is connected to a fixing plate 28. The frame 12 has a positioning groove 29 corresponding to the size of the fixing plate 28.

[0053] It should be noted that the drive component 23 drives the brush wheel 17 to rotate axially, while the lifting component 22 is used to move the brush wheel 17 up and down. In traditional brush grinding devices, the lifting component 22 is fixed to the base of the housing by bolt connection, which can easily cause instability and vibration of the entire brush wheel 17, especially when the dynamic balance fails, the shaking is more obvious, which not only increases the noise. In this embodiment, the lifting component 22 is directly fixed to the frame 12 by a connector. Compared with the fixed method of bolt connection, it not only improves the stability and vibration resistance of the brush wheel 17 and even the entire brush grinding device, increases rigidity, but also reduces the number of parts and saves costs. At the same time, the frame 12 has a positioning groove 29 corresponding to the size of the fixing plate 28, which improves the installation accuracy of the lifting component 22 and shortens the installation time of the lifting component 22.

[0054] In one embodiment, the lifting components 22 located on both sides of the housing of the brush assembly 1 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 22 through a flange coupling, and the other end is connected to the lifting component 22 through a keyless bearing 26. This ensures that after the lifting component 22 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 the installation design defects.
