Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel plate processing equipment, in particular to a cleaning device for steel plate pretreatment. BACKGROUND

[0002] Hot-dip plating is an economical and effective surface treatment method for steel materials, and hot-dip aluminum-zinc products play a very important role in reducing corrosion and prolonging the service life of steel plates, saving energy and materials. Before the steel plate is plated with aluminum-zinc, the steel plate needs to be cleaned first.

[0003] A steel plate cleaning device is disclosed in Chinese Patent Publication No. CN106423933A, which includes a support and a traction mechanism and a cleaning mechanism arranged on the support. The traction mechanism includes a fixed frame, a transmission belt and a motor, the fixed frame is fixed on the support, a driven wheel and a driving wheel are arranged above and below the fixed frame, and the driven wheel and the driving wheel have a passage for the movement of the steel plate therebetween. The cleaning mechanism is arranged between the two groups of traction mechanisms, and the cleaning mechanism includes a door-shaped support, an upper cleaning plate and a lower cleaning plate. A cylinder is fixedly installed above the door-shaped support, the output end of the cylinder penetrates through the top end of the door-shaped support and is connected with the upper cleaning plate, the lower cleaning plate is arranged on the support post of the door-shaped support corresponding to the upper cleaning plate, and cleaning strips are respectively installed on the upper cleaning plate and the lower cleaning plate. A cleaning mechanism is arranged between adjacent traction mechanisms and cleaning mechanisms, and the cleaning mechanism includes multiple groups of brush wheels and spray heads. The brush wheels are uniformly arranged between adjacent traction mechanisms and cleaning mechanisms, and the spray heads are symmetrically arranged between the brush wheels. The stainless steel plate to be cleaned is introduced from the passage between the driven wheel and the driving wheel of the traction device, the motor is started, the driven wheel and the driving wheel clamp the stainless steel plate, and the stainless steel plate is conveyed forward. When the stainless steel plate passes through the cleaning mechanism, the cylinder at the top end of the door-shaped support is started to drive the upper cleaning plate to approach the upper surface of the stainless steel plate, and the cleaning strips respectively installed on the upper cleaning plate and the lower cleaning plate clean the upper and lower surfaces of the stainless steel plate respectively.

[0004] The above cleaning device solves the problem of automatic cleaning of the steel plate. However, the above steel plate cleaning device also has certain deficiencies. This is because, for the steel plate in the cleaning process (between the driven wheel and the driving wheel), the brush wheels are arranged on both sides of the steel plate, that is, the brushes on the brush wheels directly contact the steel plate and provide support for the steel plate. However, the relatively soft brushes cannot effectively support the steel plate (especially the high-speed moving steel plate on the aluminum-zinc plating production line), which may cause the brushes to fail to effectively brush the surface of the steel plate. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the above problems and as much as possible improve the brushing effect of the steel plate, the present application provides a cleaning device for steel plate pretreatment.

[0006] The application provides a cleaning device for steel plate pretreatment, which adopts the following technical scheme:

[0007] The cleaning device for steel plate pretreatment comprises a brushing tank, a spraying pipe, a plurality of groups of brushing roller groups connected to the brushing tank, the plurality of groups of brushing roller groups are sequentially distributed along the steel plate conveying direction, the spraying pipe is used for spraying cleaning liquid to the steel plate, the brushing roller group comprises a bristle roller and a supporting roller, and the bristle roller and the supporting roller are spaced apart along the vertical direction; along the vertical direction, the bristle roller and the supporting roller correspond to each other, and along the steel plate conveying direction, the adjacent brushing roller groups are arranged in a staggered mode.

[0008] By adopting the above technical scheme, when brushing, the steel plate is located between the bristle roller and the supporting roller after entering the brushing tank, and the spraying pipe sprays cleaning liquid to the steel plate, the supporting roller directly contacts the steel plate and supports the steel plate, compared with the bristle roller, the relatively flat roller body of the supporting roller has a more stable supporting effect on the steel plate, on the one hand, the cleaning effect of the bristle roller on the steel plate is ensured, and the impurity content on the surface of the steel plate is less, on the other hand, the more stable supporting effect reduces the occurrence of the deviation of the steel plate caused by the reaction force of the bristle roller during the brushing process of the bristle roller on the steel plate as far as possible, and the product quality of the aluminum-zinc plated steel plate is ensured under the joint action of the two.

[0009] It can be understood that, among them, the bristle roller and the supporting roller correspond to each other along the vertical direction, specifically, the bristle roller is located above the supporting roller or below the supporting roller. The staggered arrangement in the application specifically means that if the bristle roller in a group of brushing roller groups is located above the steel plate (that is, the supporting roller is located below the bristle roller), the bristle roller in another group of brushing roller groups adjacent to the group is located below the steel plate (that is, the supporting roller is located above the bristle roller), that is, the supporting rollers and the bristle rollers of the adjacent brushing roller groups are staggered, the bristle rollers contact the two sides of the steel plate and brush the two sides of the steel plate, so as to realize brushing of the two sides of the steel plate.

[0010] Optionally, the brushing roller group is connected with an adjusting assembly, and the adjusting assembly is used for driving the bristle roller and the supporting roller to slide along the vertical direction and move close to or away from each other.

[0011] By adopting the above technical scheme, the thicknesses of different batches of steel plates are different, when brushing different batches (different thicknesses) of steel plates, the bristle roller and the supporting roller are driven to slide along the vertical direction by the adjusting assembly, so as to change the distance between the bristle roller and the supporting roller, so as to facilitate the passing of the steel plates with different thicknesses, and ensure that the bristle roller has a suitable interval with the steel plate, further optimize the overall cleaning effect, and then ensure the overall quality of the steel plate after aluminum-zinc plating.

[0012] Optionally, the inner wall of the brushing groove is provided with a plurality of sliding grooves, the length direction of the sliding grooves is consistent with the vertical direction, the sliding grooves correspond to the brushing roller groups one by one, the adjusting assembly comprises a threaded rod, a first motor, a first sliding block and a second sliding block, the length direction of the threaded rod is consistent with the vertical direction, the threaded rod is rotationally connected in the sliding groove, the first motor is connected to the brushing groove, the output shaft of the first motor is connected to one end of the threaded rod, the threaded rod comprises a normal threaded segment and a reverse threaded segment, the first sliding block and the second sliding block are threadedly sleeved on the normal threaded segment and the reverse threaded segment respectively, the first sliding block and the second sliding block are slidingly connected in the sliding groove along the vertical direction, the bristle roller is connected to the first sliding block, and the support roller is connected to the second sliding block.

[0013] By adopting the above technical scheme, the first motor drives the threaded rod to rotate, thereby driving the first sliding block and the second sliding block to slidingly connect in the sliding groove along the vertical direction, so that the first sliding block and the second sliding block are close to or away from each other, thereby adjusting the distance between the bristle roller and the support roller, facilitating the passage of steel plates of different thicknesses, so that the bristle roller has a suitable distance from the steel plate, and the support roller has a suitable distance from the bristle roller, thereby improving the brushing effect of the brushing roller group on the steel plate.

[0014] Optionally, the bristle roller is connected to the first sliding block through a first moving block, the first moving block is connected to one end of the bristle roller and slidingly connected to the first sliding block, the first sliding block is connected with a first moving piece, and the first moving piece is used to drive the first moving block to move along the steel plate conveying direction; the support roller is connected to the second sliding block through a second moving block, the second moving block is connected to one end of the support roller and slidingly connected to the second sliding block, the second sliding block is connected with a second moving piece, and the second moving piece is used to drive the second moving block to move along the steel plate conveying direction.

[0015] By adopting the above technical scheme, the conventional thickness of the aluminum-zinc plated steel plate is about 0.3-0.6mm, which is relatively thin, so there is a small amplitude of bending during operation. Different types of steel plates have different thicknesses, and different thicknesses of steel plates produce different bending amplitudes during production. When brushing steel plates of different bending amplitudes, the first moving piece drives the first moving block to move along the steel plate conveying direction, and the second moving piece drives the second moving block to move along the steel plate conveying direction, thereby adjusting the distance between the bristle roller and the support roller in the horizontal direction, so as to make the support roller and the bristle roller fully contact the steel plate as much as possible, improve the brushing effect of the bristle roller on the steel plate, and improve the supporting effect of the support roller on the steel plate, thereby adapting to steel plates of different bending amplitudes.

[0016] Optionally, the first sliding block is provided with a first moving groove, the length direction of the first moving groove is consistent with the steel plate conveying direction, the first moving block is slidingly connected in the first moving groove along the steel plate conveying direction, a push plate is slidingly connected in the first moving groove, the length direction of the push plate is consistent with the length direction of the first moving groove, the push plate is slidingly connected in the first moving groove along the vertical direction, the push plate is located on the side of the first moving block away from the second moving block, the first moving block is slidingly connected to the push plate along the steel plate conveying direction, the first moving groove is connected with a first spring, the length direction of the first spring is consistent with the vertical direction, one end of the first spring is connected to the inner wall of the first moving groove away from the second moving block, the other end of the first spring is connected to the push plate away from the first moving block, when the bristle roller contacts the steel plate, the first spring is compressed and deformed.

[0017] By adopting the above technical scheme, the bristle roller is easy to wear after long-term use, and when the bristle roller is worn and a gap is generated between the bristle roller and the steel plate, the first spring restores its shape and pushes the push plate and the bristle roller to move along the vertical direction, so that the bristle roller is tightly pressed against the steel plate, thereby improving the brushing effect of the bristle roller on the steel plate.

[0018] Optionally, the first moving member is a first air cylinder connected to the first sliding block, a connecting block is connected to the piston rod of the first air cylinder, a connecting groove is formed on the side of the first moving block close to the first air cylinder for embedding the connecting block, the connecting block is a T-shaped block, and the connecting groove is a T-shaped groove.

[0019] By adopting the above technical scheme, when the first spring pushes the push plate and the first moving block to move along the vertical direction, the connecting block is slidingly connected in the connecting groove along the vertical direction, thereby reducing the influence of the first air cylinder on the vertical movement of the first moving block.

[0020] Optionally, the first moving block is provided with a sliding groove, the sliding groove is formed on the side of the first moving block close to the brushing roller group, the length direction of the sliding groove is consistent with the length direction of the bristle roller, a connecting sleeve is slidingly connected in the sliding groove, the length direction of the connecting sleeve is consistent with the length direction of the bristle roller, the connecting sleeve is slidingly connected in the sliding groove along the length direction of the bristle roller, the connecting sleeve is rotationally connected in the sliding groove, the connecting sleeve is slidingly sleeved on the bristle roller, two connecting sleeves are respectively sleeved on the two ends of the bristle roller along the length direction of the bristle roller, the center axis of the connecting sleeve is collinear with the center axis of the bristle roller, and the bristle roller is provided with a locking assembly at both ends along the length direction, and the locking assembly is used for locking the connecting sleeve on the bristle roller.

[0021] By adopting the above technical solution, when replacing or cleaning the brush roller, the brush roller is disassembled, the locking component is unlocked to lock the connecting sleeve and the brush roller, and the connecting sleeve is slid along the length of the brush roller so that the connecting sleeve is away from the brush roller, thereby facilitating the removal of the brush roller from the cleaning tank, thus facilitating the cleaning and replacement of the brush roller.

[0022] Optionally, the brush roller has mounting grooves at both ends along its length, and each mounting groove corresponds to a locking component. The length direction of the mounting groove is consistent with the radial direction of the brush roller. The locking component includes a second spring and a locking block. The length direction of the second spring is consistent with the radial direction of the brush roller. One end of the second spring is connected to the inner wall of the mounting groove, and the other end of the second spring is connected to the locking block. The locking block is slidably connected to the mounting groove along the radial direction of the brush roller. The connecting sleeve has a locking hole on its periphery, and the locking block passes through the locking hole.

[0023] By adopting the above technical solution, during use, the locking block passes through the locking hole. When disassembling the brush roller, pressing the locking block causes it to embed into the mounting groove, thus facilitating the movement of the connecting sleeve and moving it away from the brush roller, thereby facilitating the disassembly of the brush roller. When installing the brush roller, the connecting sleeve moves along its length, with one end of the connecting sleeve fitted onto one end of the brush roller. Guided by the connecting sleeve, the locking block embeds into the mounting groove, and the second spring deforms under compression. When the locking block approaches the locking hole, the second spring returns to its shape and pushes the locking block to move radially along the brush roller. The second spring drives the locking block through the locking hole, thus ensuring that the brush roller is stably connected to the brushing tank.

[0024] Optionally, a second motor is connected to a connecting sleeve at one end of the brush roller. The second motor is connected to a first moving block. The output shaft of the second motor is connected to a connecting rod. The length direction of the connecting rod is consistent with the length direction of the brush roller. The end of the connecting sleeve away from the brush roller is slidably fitted onto the connecting rod. The central axis of the connecting rod is collinear with the central axis of the connecting sleeve. A limiting block is connected to the periphery of the connecting rod. A limiting groove is formed on the inner wall of the connecting sleeve. The length direction of the limiting groove is consistent with the length direction of the connecting sleeve. The limiting block is slidably connected to the limiting groove along the length direction of the connecting sleeve.

[0025] By adopting the above technical solution, when installing the brush roller, the connecting sleeve is fitted onto the brush roller. In use, the second motor drives the connecting rod to rotate. Due to the limiting effect of the limiting block and the limiting groove, the connecting rod drives the connecting sleeve and the brush roller to rotate, so that the connecting sleeve rotates stably in a predetermined direction.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When brushing, the steel plate enters the brushing tank, and the brush roller brushes the two sides of the steel plate respectively, thereby reducing the impurities on the surface of the steel plate, and the supporting roller supports the steel plate, so that the steel plate is stably placed between the supporting roller and the brush roller, the offset of the steel plate during brushing is reduced, and the brushing effect is improved;

[0028] 2. By setting the adjusting assembly, the adjusting assembly is used to adjust the distance between the brush roller and the supporting roller, so as to ensure that the brush roller and the steel plate maintain a proper distance, and then ensure the overall cleaning effect of the steel plate;

[0029] 3. When brushing the steel plate with different bending amplitudes, the first moving piece drives the first moving block to move along the steel plate conveying direction, and the second moving piece drives the second moving block to move along the steel plate conveying direction, so as to adjust the distance between the brush roller and the supporting roller in the horizontal direction, so that the supporting roller and the brush roller can fully contact the steel plate, improve the brushing effect of the brush roller on the steel plate, and improve the supporting effect of the supporting roller on the steel plate, so as to adapt to the steel plate with different bending amplitudes.

The first sliding block 400 is provided with a first moving groove 420 on the side close to the bristle roller 210, and the length direction of the first moving groove 420 is consistent with the length direction of the brushing groove 100. The first moving block 410 is slidably connected to the first moving groove 420 in the length direction of the brushing groove 100. The first sliding block 400 is connected with a first moving piece, and the first moving piece is used to drive the first moving block 410 to be slidably connected to the first moving groove 420 in the length direction of the brushing groove 100.

The first moving block 410 provided at one end of the bristle roller 210 is connected with a second motor 440, and the second motor 440 is detachably connected to one end of the bristle roller 210.

When the bristle roller 210 and the supporting roller 220 correspond one by one in the vertical direction, the contact area of the bristle roller 210 with the steel plate is relatively small, at this time, the brushing capacity of the bristle roller 210 is relatively low, but the wear caused by friction during the brushing of the bristle roller 210 is also relatively small, at this time, the service life of the bristle roller 210 is greatly prolonged. When the bristle roller 210 and the supporting roller 220 have a suitable spacing in the horizontal direction, that is, the steel plate and the bristle roller 210 form a suitable size of the wrap angle, the contact area of the bristle roller 210 with the steel plate is large, and the brushing effect of the bristle roller 210 on the steel plate is relatively good, but the wear caused by friction during the brushing of the bristle roller 210 is also relatively large, therefore, the operator can adjust the relative positions of the bristle roller 210 and the supporting roller 220 in the brush roller group 200 according to the processing requirements of different sample plates, so that the bristle roller has high brushing effect and low wear to some extent.

The length direction of the limiting groove 452 is consistent with the length direction of the connecting sleeve 450, and the limiting block 442 is slidingly connected to the limiting groove 452 along the length direction of the connecting sleeve 450.

[0056] When the bristle roller 210 is disassembled, the locking block 620 is pressed, so that the locking block 620 is away from the locking hole 451. Thus, the connecting sleeve 450 is away from the bristle roller 210, and the disassembly of the bristle roller 210 is more convenient. The replacement and brushing of the bristle roller 210 are facilitated.

[0057] With reference to Figure 4 And Figure 5A push plate 460 is slidably connected within the first moving groove 420. The length direction of the push plate 460 is consistent with the length direction of the first moving groove 420, and both ends of the push plate 460 contact the corresponding inner walls of the first moving groove 420 along its length direction. The push plate 460 is slidably connected within the first moving groove 420 in the vertical direction. The push plate 460 is located on the side of the first moving block 410 away from the second moving block 510, and the first moving block 410 is connected to the push plate 460 on the vertical side. The first movable block 410 is slidably connected to the push plate 460 along the length of the scrubbing groove 100. The first movable block 410 is connected to the first block 412 near the push plate 460. The first block 412 is T-shaped. The push plate 460 is provided with a first groove 461 for the first block 412 to be inserted into on the side near the first movable block 410. The length of the first groove 461 is consistent with the length of the scrubbing groove 100. The first groove 461 is T-shaped. The first block 412 is slidably connected to the first groove 461 along the length of the scrubbing groove 100.

[0058] Reference Figure 4 A first spring 470 is connected inside the first moving groove 420. Several first springs 470 are provided, spaced apart along the length of the first moving groove 420, with the length of the first spring 470 aligned with the vertical direction. One end of each first spring 470 is connected to the side of the push plate 460 away from the first moving block 410, and the other end is connected to the inner wall of the first moving groove 420. When the brush roller 210 contacts the steel plate, the first spring 470 is compressed and deformed.

[0059] Reference Figure 4 and Figure 7 The piston rod of the first cylinder 430 is connected to a connecting block 431. The first moving block 410 has a connecting groove 413 for the connecting block 431 to be embedded on the side near the first cylinder 430. The connecting block 431 is a T-shaped block and the connecting groove 413 is a T-shaped groove. The connecting block 431 is slidably connected to the connecting groove 413 in the vertical direction.

[0060] When the brush roller 210 wears down, the first spring 470 drives the brush roller 210 to press against the steel plate, thereby improving the brushing effect of the brush roller 210 on the steel plate.

[0061] The implementation principle of the cleaning device for steel plate pretreatment is as follows: during brushing, the steel plate passes through the gap between the brush roller 210 and the supporting roller 220, the brush roller 210 rotates and brushes the steel plate, the supporting roller 220 supports the steel plate at the same time, and the spray head 151 sprays cleaning liquid to the steel plate, so as to avoid the offset of the steel plate during brushing as much as possible, and thus improve the brushing effect. When the types of the brushed steel plates are different, the first motor 320 drives the threaded rod 310 to rotate, so as to drive the first sliding block 400 and the second sliding block 500 to move along the vertical direction, and drive the first sliding block 400 and the second sliding block 500 to move close to each other or move away from each other, so as to adjust the distance between the brush roller 210 and the supporting roller 220, so as to adapt to steel plates with different thicknesses. The first cylinder 430 drives the first moving block 410 to slide in the first moving groove 420 along the length direction of the brushing groove 100, and the second cylinder 530 drives the second moving block 510 to slide in the second moving groove 520 along the length direction of the brushing groove 100, so as to change the horizontal distance between the brush roller 210 and the supporting roller 220, so as to adapt to steel plates with different bending amplitudes.

[0062] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
