Description

Technical Field

[0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a steel plate brush treatment assembly. Background Art

[0002] When rust forms on the surface of a steel plate, the oxide scale on the surface needs to be promptly treated, otherwise it will not only affect the appearance but also the usability. A previously applied patent document with the number 201921666810.5 discloses a device for removing rust from the surface of a steel plate. A scale-breaking roller for brushing the steel plate is mounted on a working main beam. The working main beam is movably mounted below the upper beam via a vertical beam, and the height of the scale-breaking roller can be adjusted vertically. The upper beam is then slidably connected to the upper bracket, allowing the scale-breaking roller to slide along the width of the steel plate to adjust its brushing position. However, the problem is that this grinding method can only grind the upper surface of the steel plate. If the steel plate passes over the scale-breaking roller, the length of the scale-breaking roller needs to be increased to prevent the vertical beam from obstructing the steel plate. However, as the length of the scale-breaking roller increases, the stability is not enough when rotating at high speed. In addition, this device is not very convenient when changing rollers. When changing rollers, the production line needs to stop working, and then the roller changing mechanism is moved to the steel plate surface rust remover, and the scale-breaking roller is removed and replaced with a new one, which undoubtedly increases the difficulty of the operator in actual operation.

[0003] In subsequent production practice, a steel plate surface treatment device with application number CN202111287159.2, which is convenient for roller changing, was proposed. Multiple brush rollers are arranged at intervals on the upper and lower surfaces of the steel plate, thereby improving the efficiency of brushing; the device also has a working area and a roller changing area. The brush roller is installed on the mounting seat, and the mounting seat is connected to the bearing seat and can be raised and lowered on the bearing seat. The bearing seat can slide on the base along the width direction of the steel plate, so that the brush roller can be moved from the working area to the roller changing area. Online roller changing can be achieved without stopping the machine to change the roller, which is also convenient for the operator to operate. However, the shortcomings are: 1. When the steel plate is fed over or under the brush roller for brushing, the brush roller will cause the steel plate to deform upward or downward, resulting in poor brushing effect. Even if a roller is provided above or below the brush roller to support the steel plate, it is not stable enough during brushing. Therefore, the collision between the steel plate and the roller during brushing will produce a large noise; 2. In order to ensure sufficient brushing, two staggered upper brush roller groups are arranged on the upper surface of the steel plate, and two staggered lower brush roller groups are arranged on the lower surface of the steel plate to ensure sufficient brushing. It is obvious that the brush rollers in the brush roller group need to extend outward on both sides of the steel plate to ensure that there are no dead angles for brushing during brushing. However, after the brushing is completed, there must be a section of unworn abrasive at the end of the brush roller. At this time, the brush roller can no longer continue to brush other steel plates due to this unworn part, which will cause waste. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a steel plate brush processing assembly, which uses a pair of roller groups to simultaneously brush the upper and lower surfaces of the steel plate, and each two pair of roller groups are staggered in the width direction of the steel plate to ensure that the upper and lower surfaces of the steel plate are fully brushed; the upper half roller and the lower half roller in the pair of roller groups are aligned up and down, and can clamp the steel plate at the same time to avoid distortion of the steel plate and keep the steel plate stable and straight; in the working state, the outer ends of the half rollers in the two pair of roller groups extend outward on both sides of the steel plate, and the inner ends of the half rollers in the two half roller groups are staggered and overlapped in the width direction of the steel plate. In the adjustment state, the two pair of roller groups move toward each other, the inner ends of the half rollers extend outward on both sides of the steel plate, and the outer ends of the half rollers are staggered and overlapped in the width direction of the steel plate, and switched to the working state.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A steel plate brushing assembly includes a plurality of roller devices arranged in the feeding direction of the steel plate, each roller device includes at least two roller groups, the two roller groups are arranged in a front-to-back manner along the feeding direction of the steel plate, and the two roller groups are staggered in the width direction of the steel plate; the roller group includes a half roller for brushing the steel plate, and the roller group can also move along the width direction of the steel plate to adjust the position of the half roller on the surface of the steel plate, the half roller includes an upper half roller arranged on the upper surface of the steel plate and a lower half roller arranged on the lower surface of the steel plate, and the axes of the upper half roller and the lower half roller are located on the same vertical line The two roller groups are staggered and arranged on the steel plate feeding route, and the outer ends of the half rollers in the two roller groups extend outward on both sides of the steel plate respectively, and the inner ends of the half rollers in the two roller groups are staggered and overlapped in the width direction of the steel plate to brush the same position of the steel plate together to achieve complete brushing of the steel plate; in the adjustment state, the two roller groups move toward each other, the inner ends of the half rollers extend outward on both sides of the steel plate, and the outer ends of the half rollers are staggered and overlapped in the width direction of the steel plate to brush the same position of the steel plate together, and then switch to the working state again.

[0007] Compared to traditional single-roller brushing, the paired-roller brushing method significantly improves brushing effectiveness and eliminates the warping and deformation of the steel plate that occurs with traditional brushing. The two half-rollers not only brush but also support the steel plate. When the steel plate bends upward or downward during brushing, the upper or lower half-roller limits the bending while also brushing. Compared to using support rollers directly on the steel plate surface, the paired-roller brushing method also generates less noise. Furthermore, each paired-roller unit features at least two staggered pairs of rollers, ensuring full coverage across the width of the steel plate to ensure adequate brushing. At the beginning of brushing, the two pairs of rollers are arranged in a staggered manner, with the outer ends of the half rollers extending outwards from both sides of the steel plate, while the inner ends overlap in an staggered manner to ensure brushing without dead angles. The overlapping parts can also improve the brushing effect, and a part of the half rollers extending outwards from both sides of the steel plate will not be worn. After brushing for a period of time, the two pairs of rollers move toward each other, so that the inner ends of the half rollers that were originally staggered and overlapped extend outwards from both sides of the steel plate, while the outer ends overlap in an staggered manner to brush the same position of the steel plate together. At this time, the parts that were not worn before also participate in the wear, thereby causing the abrasives on the half rollers to wear synchronously. On the one hand, this improves the brushing effect and the utilization rate of the half rollers. On the other hand, if the abrasives are not completely worn out, the half rollers can be brushed a second time due to the synchronization of abrasive wear, further improving the utilization rate.

[0008] Preferably, the roller assembly further comprises a frame; each roller group comprises two parallel lower rails disposed at the bottom of the frame and two parallel upper rails disposed at the top of the frame; a lower roller seat for mounting the lower half roller is slidably connected to the lower rails, and an upper roller seat for mounting the upper half roller is slidably connected to the upper rails; a movable area for sliding the upper roller seat and extending vertically is also provided at the top of the frame between the same set of upper rails; both the lower and upper roller seats are equipped with horizontal displacement mechanisms to drive the roller group to move along the width of the steel plate. The frame provides connection points for the roller groups and space for each roller group to replace the rollers after the abrasive on the half roller is completely worn, making roller replacement more convenient.

[0009] Preferably, a lower support seat is provided below the lower roller seat, and an upper support seat is provided above the upper roller seat. The lower support seat and the upper support seat are fixed relative to the frame in the working state, and can move relative to the frame in the horizontal direction in the adjustment state. A lifting mechanism is provided between the lower roller seat and the lower support seat, as well as between the upper roller seat and the upper support seat, to adjust the vertical position of the lower roller seat and the upper roller seat so that the lower half roller and the upper half roller are always in contact with the surface of the steel plate. During the grinding process, the abrasive on the half roller will gradually wear out. If the position of the half roller is always fixed, after a period of time, the abrasive on its surface will not be able to grind the surface of the steel plate. The lifting mechanism can adjust the distance between the lower roller seat and the lower support seat, as well as the distance between the upper roller seat and the upper support seat, so that the half roller can always be in contact with the surface of the steel plate. The lower support seat and the upper support seat are relatively fixed to the frame in the working state, which can ensure stability during the brushing process and facilitate the adjustment of the position of the lower roller seat and the upper roller seat; in the roller changing state, they can move in the horizontal direction of the frame, which makes it easy for the lower support seat and the upper support seat to move with the lower roller seat and the upper roller seat, thereby facilitating roller changing.

[0010] Preferably, the front and rear side walls of the lower support seat have an extended lower pressure platform; the front and rear side walls of the upper support seat also have an extended upper pressure platform; each pair of roller groups also includes two symmetrically arranged lower fixed seats arranged at the bottom of the frame, and two symmetrically arranged upper fixed seats arranged at the top of the frame; the opposite side walls of the two lower fixed seats are provided with lower guide grooves for accommodating the lower pressure platforms, and the opposite side walls of the two upper fixed seats are provided with upper guide grooves for accommodating the upper pressure platforms; the lower fixed seat and the upper fixed seat are both provided with at least two hydraulic locking mechanisms. In the working state, after the roller group moves to the corresponding position, the hydraulic locking mechanism can press and fix the lower pressure platform and the upper pressure platform to the corresponding side walls of the lower guide groove and the upper guide groove to achieve stable operation of the roller group. When the roller is changed, the lower roller seat is first moved back to the lower rail by the lifting mechanism, and then the hydraulic locking mechanism is released, and the lifting mechanism is started again to make the lower support seat disengage from the bottom surface of the lower guide groove, and then the lower roller seat is driven by the horizontal displacement mechanism to move out of the steel plate surface along the width direction of the steel plate to change the roller. The hydraulic locking mechanism can make the entire mechanism more stable in working condition, thereby indirectly improving the grinding effect.

[0011] Preferably, the lifting mechanism comprises a lifting base disposed within the lower roller seat and the upper roller seat, the top of the lifting base being fixedly connected to a transmission mechanism, the transmission mechanism being built into a worm gear mechanism, the end of the worm gear being fixedly connected to a transmission shaft extending outwardly from the lower roller seat and the upper roller seat, a lifting motor being provided on the sidewalls of each of the lower roller seat and the upper roller seat, the lifting motor being connected to the transmission shaft; a screw being connected to the axis of the worm gear, a hollow sleeve being fixedly connected to the lower support seat and the upper support seat, the end of the sleeve being fixedly connected to a nut that engages with the screw gear; the lifting motor drives the screw gear to rotate through the transmission of the worm gear mechanism, thereby engaging with the nut, and the nut and sleeve being fixedly connected and unable to rotate relative to each other in the circumferential direction, thereby enabling adjustment of the distance between the lower support seat and the lower roller seat, or adjustment of the distance between the upper support seat and the upper roller seat, by rotation of the screw gear; taking the lower support seat and the lower roller seat as an example, when the lower roller seat is relatively fixed, the lower support seat is the one that undergoes the lifting action; similarly, when the lower support seat is relatively fixed, the lower roller seat can undergo the lifting action.

[0012] Preferably, the hydraulic locking mechanism includes a hydraulic seat with a hollow interior, wherein the hydraulic seat is provided with a pressure column in the vertical direction, and two symmetrical pressure grooves are provided on the circumferential side walls of the pressure column, the bottom of the pressure grooves being inclined upward; the hydraulic seat is also provided with a movable pressure block that can be inserted into the pressure groove, and the bottom of the movable pressure block is also inclined upward at the same angle as the inclination of the pressure groove; the side wall of the hydraulic seat is also provided with a first oil cylinder, the piston rod of the first oil cylinder is placed in the hydraulic seat and acts on the movable pressure block; in the working state, the movable pressure block slides in the hydraulic seat through the drive of the first oil cylinder, thereby driving the pressure column to extend outward and press down the lower pressure platform and the upper pressure platform. The movable pressure block can be pushed by the oil cylinder to slide, and the inclined setting of the bottom surface of the movable pressure block cooperates with the inclined setting of the bottom of the upper pressure groove, so that the movable pressure block presses the pressure column to extend outward during the horizontal displacement process, and then presses against the lower pressure platform and the upper pressure platform, thereby fixing the lower support seat and the upper support seat.

[0013] Preferably, the horizontal displacement mechanism includes a rotating shaft extending through the lower and upper roller seats, respectively, with both ends of the rotating shaft extending outward from the lower and upper roller seats and connected to rollers. Each of the lower and upper roller seats is equipped with a horizontal displacement motor, with gears connected to the output end of the horizontal displacement motor and the rotating shaft, and a transmission chain connected to the gears between the output end of the horizontal displacement motor and the rotating shaft. In the adjusted state, the horizontal displacement motor drives the chain to rotate, causing the lower and upper roller seats to be horizontally displaced on the lower and upper rails, respectively, via the rollers. The majority of the transmission gear chain is located inside the lower or upper roller seat, saving space and providing protection against accidental collisions or jams.

[0014] Preferably, the lower and upper roller seats are connected at either end to a fixed bearing seat for supporting the half roll and a movable bearing seat, respectively. The movable bearing seat is slidably connected to the bearing housing. A second oil cylinder is also provided on the sidewall of the bearing housing to drive the movable bearing seat to extend or retract into the bearing housing for roll changing. In operation, the movable bearing seat extends outward to support the half roll, but retracts into the bearing housing during roll changing, effectively protecting the movable bearing seat from damage caused by collisions during roll changing.

[0015] Preferably, each pair of roller groups is equipped with support devices on both the front and rear sides of the steel plate feeding direction to support the steel plate for smooth feeding. The support devices include at least three support rollers arranged in a triangular shape. Compared with a traditional single roller or two support rollers arranged one above the other, the triangular arrangement of support rollers provides more stable support and can also prevent bending deformation of the steel plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Compared with the traditional single-roller brushing method, the double-roller brushing method can greatly improve the brushing effect, and will not cause the steel plate to warp and deform during traditional brushing. The two half-rollers not only play the role of brushing, but also support the steel plate. When the steel plate bends upward or downward during the brushing process, the half-roller located above or below can limit its bending while also performing brushing.

[0018] The half-roller brush method also reduces noise compared to the method of arranging rollers on the surface of the steel plate.

[0019] In addition, at least two staggered roller groups are set in each roller device, which can completely cover the width direction of the steel plate to ensure sufficient brushing. At the beginning of brushing, the two roller groups are staggered, and the outer ends of the half rollers extend outwards from both sides of the steel plate, while the inner ends overlap in an interlaced manner to ensure brushing without dead angles. The overlapping parts can also improve the brushing effect, and a part of the half rollers extending outwards from both sides of the steel plate will not be worn. After brushing for a period of time, the two roller groups move toward each other, so that the inner ends of the half rollers that were originally staggered and overlapped extend outwards from both sides of the steel plate, while the outer ends overlap in an interlaced manner to brush the same position of the steel plate together. At this time, the previously unworn parts also participate in the wear, thereby causing the abrasive on the half rollers to wear synchronously. On the one hand, this improves the brushing effect and the utilization rate of the half rollers. On the other hand, if the abrasive is not completely worn, the synchronization of the abrasive wear also allows the half rollers to be brushed a second time, further improving the utilization rate.

[0037] The following is a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0038] In this embodiment, Figure 1-3 As shown, a steel plate brushing processing assembly is specifically disclosed, including a plurality of roller devices arranged in the feeding direction of the steel plate, each roller device includes at least two roller groups, the two roller groups are arranged in a front-to-back interval along the feeding direction of the steel plate, and the two roller groups are staggered in the width direction of the steel plate; the roller group includes a half roller 5 for brushing the steel plate, and the roller group can also be moved along the width direction of the steel plate to adjust the position of the half roller 5 on the surface of the steel plate, the half roller 5 includes an upper half roller 501 arranged on the upper surface of the steel plate and a lower half roller 502 arranged on the lower surface of the steel plate, and the upper half roller 501 and the lower half roller 502 are respectively arranged on the upper surface of the steel plate. The axes of 02 are located on the same vertical line to form a pair of brushes for the steel plate; the processing assembly has a working state and an adjustment state. In the working state, the two pairs of roller groups are staggered on the steel plate feeding route, and the outer ends of the half rollers 5 in the two pairs of roller groups extend outward on both sides of the steel plate, and the inner ends of the half rollers 5 in the two pairs of roller groups are staggered and overlapped in the width direction of the steel plate to jointly brush the same position of the steel plate to achieve complete brushing of the steel plate; in the adjustment state, the two pairs of roller groups move toward each other, the inner ends of the half rollers 5 extend outward on both sides of the steel plate, and the outer ends of the half rollers 5 are staggered and overlapped in the width direction of the steel plate to jointly brush the same position of the steel plate, and then switch to the working state again.

[0039] In this way, not only can the steel plate be completely brushed, but the utilization rate of the half roller 5 can also be improved. In the initial stage of brushing, the outer ends of the half rollers 5 in the two pairs of roller groups extend out of both sides of the steel plate, that is, one end of the upper half roller 501 and the lower half roller 502 located on the upper and lower surfaces of the steel plate in each pair of roller groups extends outward on one side of the steel plate, while the inner ends of the half rollers 5 in the two pairs of roller groups are staggered and brush the same position on the surface of the steel plate, which also improves the brushing effect; after brushing for a period of time, the originally extended half roller 5 is moved toward each other in the width direction of the steel plate, that is, the outer end of the previously extended half roller 5 is moved toward the middle position of the steel plate, and the inner end of the brush roller 5 previously located on the surface of the steel plate is moved toward the side of the steel plate, so that the inner end extends outward from the side of the steel plate, and the outer end moves to the surface of the steel plate, thereby ensuring that the abrasive on the surface of the brush roller 5 is worn synchronously, thereby improving the utilization rate of the brush roller 5, so that the abrasive on the surface of the brush roller 5 can be used for the next production if it is not completely worn out.

[0040] If the conventional brushing method is used, part of the abrasive on the surface of the brush roller 5 is often worn away, while the other part is still intact. At this time, even if the brush roller is not completely worn away, the abrasive on its surface is not worn away synchronously, and the surface will be uneven and cannot be reused.

[0041] In actual production, the upper half roller 501 and the lower half roller 502 are respectively installed on the upper roller seat 201b and the lower roller seat 201a, and the upper roller seat 201b and the lower roller seat 201a are respectively mounted on the top and bottom of the frame 7, wherein the upper and lower through-active areas opened at the top of the frame 7 are for facilitating the installation of the lower roller seat 201a to form a pair of brushes on the steel plate, and the upper slide rail 701b at the top of the frame 7 and the lower slide rail 701a at the bottom also facilitate the movement of the upper roller seat 201b and the lower roller seat 201a along the width direction of the steel plate, thereby adjusting the brushing position of the brush roller 5 during the brushing process.

[0042] like Figure 3 、 7 As shown, a lower support seat 203a is provided below the lower roller seat 201a, and an upper support seat 203b is provided above the upper roller seat 201b. The lower support seat 203a and the upper support seat 203b are relatively fixed to the frame 7 in the working state, and can be relatively moved in the horizontal direction with the frame 7 in the roller changing state; a lifting mechanism 10 is provided between the lower roller seat 201a and the lower support seat 203a, and between the upper roller seat 201b and the upper support seat 203b, so as to adjust the position of the lower roller seat 201a and the upper roller seat 201b in the vertical direction so that the lower half roller 502 and the upper half roller 501 are always in contact with the surface of the steel plate.

[0043] like Figure 4 As shown, each pair of roller groups is provided with a supporting device on the front and rear sides of the steel plate feeding direction for supporting the smooth feeding of the steel plate, and the supporting device includes at least three supporting rollers 801, and the supporting rollers 801 are arranged in a triangle, and the arrangement of the supporting rollers 801 is divided into a right triangle and an inverted triangle. The supporting rollers 801 arranged in the shape of a right triangle and the supporting rollers 801 arranged in the shape of an inverted triangle are alternately arranged on the frame 7.

[0044] The lower roller seat 201a and the upper roller seat 201b are respectively connected at both ends with a fixed bearing seat 3 for supporting the half roller 5 and a movable bearing seat 402; the movable bearing seat 402 is slidably connected in the bearing box 1, and the side wall of the bearing box 1 is also provided with a second oil cylinder for driving the movable bearing seat 402 to extend or retract into the bearing box 1 to facilitate roller changing.

[0045] In addition, if Figure 1-8As shown, the front and rear side walls of the lower support seat 203a have extended lower pressing platforms 204a; the front and rear side walls of the upper support seat 203b also have extended upper pressing platforms 204b; each pair of roller groups also includes two symmetrically arranged lower fixing seats 205a provided at the bottom of the frame 7, and two symmetrically arranged upper fixing seats 205b provided at the top of the frame 7; the opposite side walls of the two lower fixing seats 205a are provided with lower guide grooves 205a for accommodating the lower pressing platforms 204a. 06a, the opposite side walls of the two upper fixed seats 205b are provided with upper guide grooves 206b for accommodating the upper pressing platform 204b; the lower fixed seat 205a and the upper fixed seat 205b are both provided with multiple hydraulic locking mechanisms. In the working state, after the roller group moves to the corresponding position, the hydraulic locking mechanism can press and fix the lower pressing platform 204a and the upper pressing platform 204b to the corresponding side walls of the lower guide groove 206a and the upper guide groove 206b to achieve stable operation of the roller group.

[0046] In actual production, the abrasive on the surface of the brush roller 5 will gradually wear out, so it is necessary to adjust the positions of the upper roller seat 201b and the lower roller seat 201a. Since the upper roller seat 201b and the lower roller seat 201a are respectively mounted on the upper slide rail 701b and the lower slide rail 701a, when the lower roller seat 201a is adjusted, the lifting mechanism 10 acting on the lower roller seat 201a and the lower support seat 203a will first act on the lower support seat 203a, first causing the lower support seat 203a to move downward, driving the lower pressing platform 204a to also move downward and press against the bottom of the lower guide groove 206a, and then the hydraulic locking mechanism acts on the lower pressing platform 204a to fix the lower roller seat 203a. At this time, the lifting mechanism 10 continues to act. Since the lower support seat 203a is fixed, the lower roller seat 201a moves relatively, realizing the lifting and lowering adjustment of the lower roller seat 201a.

[0047] When the upper roller seat 201b is adjusted, the lifter 10 acting on the upper roller seat 201b and the upper support seat 203b will first act on the upper support seat 203b when it starts to move, causing it to descend and drive the upper pressing platform 204b to press against the bottom of the upper guide groove 206b. At this time, another hydraulic locking mechanism acting on the upper pressing platform 204b presses down and locks the upper support seat 203b. When the lifting mechanism 10 continues to move, it will only drive the upper roller seat 201b to move to achieve lifting.
