Part of the zinc layer will adhere to the roller surface of the top roller of the cooling tower. If not removed, the zinc layer will continuously cross-stack, accumulate, and amplify, seriously affecting the surface quality of the strip. Utility Model Content

[0014] In one embodiment of the first aspect, the feed control assembly further includes a limiting member. One end of the telescopic rod is fixedly connected to the transmission, and the length of the telescopic rod extending between the limiting members defines the telescopic stroke distance of the first power source.

Detailed implementation manners

[0030] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0031] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0033] In this application, unless otherwise clearly specified or limited, terms such as "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In this application, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0035] In the related art, as Figure 1 shown, the polishing wheel 111 is installed on the longitudinal moving seat 132a, and the longitudinal moving seat 132a is powered by a cylinder to form pressure on the roller surface of the workpiece to be polished for polishing. Since the power of the cylinder cannot be precisely adjusted at a small pressure, when the power of the cylinder is insufficient, the longitudinal moving seat 132a will exhibit a crawling phenomenon, and the polishing wheel 111a cannot always ensure contact with the surface of the roller 200, and cannot effectively clean the roller surface. When the power of the cylinder is too large, the polishing wheel 111a wears relatively fast, has a relatively short lifespan, and there are also risks to the product quality.

[0036] To address the above problems, as Figure 2 shown, an embodiment of this application provides a rotary roller surface polishing machine 100 for improving the surface quality of a metal strip, including a feed control component and a polishing wheel component 110.

[0037] Among them, the polishing wheel component 110 includes a polishing wheel 111, and the polishing wheel 111 is used for flexibly polishing the roller surface. In this application, flexible polishing refers to polishing the polishing wheel 111 and the roller surface without pressure or with small pressure, and a polishing wheel with a flexible structure needs to be used.

[0038] The polishing effect of flexible polishing has an important relationship with the pressure value (real-time position during polishing) of the contact between the polishing wheel and the surface of the roller to be polished, the angle of the abrasive cloth blades, the rotation speed of the polishing wheel, the rotation speed of the roller surface, etc. In other words, in addition to using a flexible polishing wheel and appropriate polishing wheel rotation speed and other conditions, flexible polishing needs to meet the requirements of precise position control.

[0039] The feed control assembly includes a monitoring member (not shown in the figure), a control member (not shown in the figure), and a driving member 121. The driving member 121 includes a telescopic rod 1213. The driving member 121 drives the telescopic rod 1213 to expand and contract to dynamically adjust (limit) the position of the polishing wheel 111.

[0040] The monitoring member is used to indirectly detect the real-time position of the telescopic rod to monitor the real-time position and the limit position of the polishing wheel 111, and feedback the real-time position information to the control member. The control member adjusts the driving member 121 in real time according to the real-time position information and the requirements set by the system model in the implementation state, so that the driving member 121 drives the telescopic rod 1213 to adjust the length of the telescopic rod 1213, and the polishing wheel 111 is controlled in real time at the required polishing position.

[0041] The driving member 121 performs position adjustment with the limiting member according to the real-time position of the telescopic rod collected by the monitoring member, the real-time operating parameters of the equipment, and the set model, under the instruction of the control member, so as to realize the position adjustment of the action of the first power source, and then adjust the precise movement position of the polishing wheel 111. The polishing wheel 111 polishes the roller surface at the real-time set position, so that the polishing pressure between the polishing wheel 111 and the roller surface meets the near-zero setting, enabling the polishing wheel 111 to effectively perform flexible polishing and cleaning on the roller surface, improving the polishing efficiency, improving the polishing effect, and extending the service life of the polishing wheel 111.

[0042] In some embodiments, the monitoring member is an optical signal or electromagnetic signal sensor.

[0043] It can be understood that when using the polishing wheel 111 to clean the roller surface, there is an ideal (real-time) polishing position between the polishing wheel and the roller surface. When polishing at the ideal polishing position, the polishing wheel and the roller surface are in full contact under the action of a light pressing force and the centrifugal force component, and slide relatively at a high speed between the contact surfaces. The polishing wheel 111 can effectively clean the roller surface, without generating excessive pressure between the polishing wheel 111 and the roller surface, and can significantly extend the service life of the polishing wheel 111. Nor will it cause non-contact ineffective polishing or abnormal polishing at non-ideal positions due to position deviation. This ideal polishing position is the real-time controlled polishing position of the present application.

[0044] During the actual polishing process of the rotating roller surface, the rotation center position of the roller surface to be cleaned is fixed. Under the action of the first power source, the position of the polishing wheel (center) is controlled by dynamically analyzing the real-time position of the monitoring polishing wheel 111 (the position of the telescopic rod), the equipment operation parameters, and the polishing wheel wear model in real time. The control component performs polishing position tracking and adjustment control on the polishing wheel 111 (the position of the telescopic rod), so that the polishing wheel is always in the (set) ideal working position, achieving the set high-efficiency polishing and satisfactory polishing effect.

[0045] In some embodiments, the driving component 121 includes a servo motor 1211 and a gearbox 1212, and the servo motor 1211 and the gearbox 1212 are connected by a coupling.

[0046] The monitoring component includes a rotary encoder, and the servo motor 1211 is connected to the rotary encoder. The control component has storage and dynamic analysis functions. The control component controls the rotation direction and the number of rotation turns of the servo motor 1211 in real time according to the real-time position information, the equipment operation parameters, and the system model.

[0047] The monitoring component further includes a limit position signal sensor.

[0048] The limit position sensor determines the limit position where the polishing wheel 111 is located by monitoring the real-time minimum or maximum telescopic stroke of the telescopic rod 1213, and grasps the real-time limit position state of the polishing wheel 111, including information that the polishing wheel is worn to the point of needing replacement, so as to issue relevant instructions.

[0049] In some embodiments, the control component can store all the operation instructions of the polishing wheel 111 from the first run to the last run. If there is no pause during the entire polishing process, the servo motor 1211 runs from start to finish according to the instructions set by the control component.

[0050] During the actual polishing process, there are often situations of pauses or other repairs. As long as the polishing wheel is not replaced, when running again after a pause, the system will automatically restore the real-time position of the polishing wheel 111. In some cases with human intervention, such as when the position of the polishing wheel changes unexpectedly after equipment maintenance, or when the equipment fails and the control program is lost, etc., the "zero position" of the polishing wheel needs to be reset, and manual confirmation is required during the setting.

[0051] For example, please refer to Figure 2 and Figure 3, when the monitoring component feedbacks that the real-time position of the polishing wheel 111 deviates 0.5 mm to the left of the preset polishing position, the control component can be required to send out corresponding rotary encoder pulse signals to make the servo motor 1211 rotate forward, driving the telescopic rod 1213 to move leftward by the required distance. After the encoder feedback reaches the set value, it stops. The corresponding number of turns for the telescopic rod 1213 to move leftward by 0.5 mm is such that the telescopic rod 1213 accurately changes the 0.5 mm difference, moving the polishing wheel 111 to the preset polishing position; vice versa. In some embodiments, the transmission 1212 has a first input end and a second input end. The first input end is connected to the servo motor 1211, and a handwheel 1214 is provided at the second input end. In this way, when the servo motor 1211 fails, the handwheel 1214 can be manually adjusted to manually adjust the position of the polishing wheel 111 to ensure that the polishing machine can operate along the main line of the production line simultaneously.

[0052] In some embodiments, such as Figure 3 shown, the feed control assembly further includes a limiting member 1215.

[0053] One end of the telescopic rod 1213 is fixedly connected to the transmission 1212, and the length at which it can be telescoped between the limiting members 1215 defines the telescopic stroke distance of the cylinder; the servo motor 1211 rotates, driving the telescopic rod 1213 to adjust the position of the polishing wheel 111 by adjusting the distance between the telescopic rod 1213 and the limiting member 1215.

[0054] In some embodiments, the driving member 121 further includes a mounting bracket 1216 and an extension plate 1217, and the driving member 121 is fixedly connected to the mounting bracket 1216.

[0055] Please refer to Figure 1 and Figure 2 , in this application, an extension plate 1217 is fixed at one end of the longitudinal moving seat 132a away from the polishing wheel 111, and a mounting bracket 1216 is connected to the end of the extension plate 1217. The driving member 121 is connected to the mounting bracket 1216. In this way, when the telescopic rod 1213 is driven by the servo motor 1211 and the transmission 1212 and controlled by the control component, the position adjustment control of the polishing wheel 111 is realized through the telescopic control of the telescopic rod 1213.

[0056] In some embodiments, the polishing machine further includes a first moving component 130 and a second moving component 140. The first moving component 130, together with the driving member 121 and the polishing wheel assembly 110, moves along the first direction under the action of a first power source 131 with one end connected to the first moving component 130 and the other end connected to the second moving component 140.

[0057] The first moving component 130 includes a first power source 131 and a first moving base 132. The polishing wheel assembly 110 and the driving member 121 are respectively connected to the first moving base 132. The first power source 131 drives the first moving base 132, the polishing wheel assembly 110 and the driving member 121 to move along the first direction, and drives the polishing wheel 111 and the driving member 121 to move to a non-polishing working state, an initial position of the polishing operation, or a required position.

[0058] The second moving component 140 drives the first moving component 130, including the driving member 121 and the polishing wheel 111, to move along the second direction. The first direction and the second direction are perpendicular.

[0059] It should be noted that the first direction refers to Figure 2 or Figure 3 the left-right direction in

[0060] The second moving component 140 includes a second power source 141 and a second moving base 142. The first moving base 132 and the second moving base 142 are connected. The second power source 141 drives the second moving base 142 and the first moving base 132 to move along the second direction.

[0061] Exemplarily, the first moving base 132 adopts a combined structure of a slide rail, a slider, and a connecting seat. Two spaced slide rails are both arranged to extend along the first direction. A plurality of sliders are slidably connected to the slide rails. The connecting seat is erected on the two slide rails and fixedly connected to the sliders. The first power source (compressed air cylinder, one end connected to the first moving base and the other end connected to the second moving base) 131 drives the sliders on the two slide rails to move synchronously, realizing the movement of the first moving base 132 along the first direction.

[0062] Exemplarily, the second moving base 142 is driven by the second power source through a motor, a lead screw, slide rails, and sliders. The lead screw is arranged between two spaced slide rails. The lead screw and the slide rails are both arranged to extend along the second direction. The second moving base 142 is connected to the slide rails on the bottom of the equipment seat through sliders, and is connected to the lead screw installed on the bearing seat through the lead screw nut on the second moving base 142. The bearing seats are respectively installed at both ends of the equipment base in the second direction. The lead screw is installed in the bearing seats through bearings and is connected to the second power source 141 at one end. When the second power source 141 drives the lead screw to rotate, the lead screw nut moves along the lead screw, thereby driving the second moving base 142 to move along the second direction.

[0063] The limiting member 1215 is fixed to the second moving base 142. One end of the air cylinder of the first power source 131 is connected to the first moving base 132, and the other end is connected to the second moving base 142.

[0064] The driving member 121 is installed on the extension plate 1217 of the first moving seat 132 corresponding to the limiting member 1215, that is, at the other end of the first moving seat 132 relative to the position of the polishing wheel 111 in the first direction. One end of the telescopic rod 1213 adjusts the positions of the first moving seat 132 and the second moving seat 142 in the first direction under the action of the first power source 131, that is, adjusts the output length of the telescopic rod 1213 to adjust the working position of the polishing wheel 111.

[0065] The limiting member 1215 and the telescopic rod 1213 are arranged along the first direction. The telescopic amount of the telescopic rod 1213, that is, the distance between the travel position sensors at both ends, determines the limit adjustment amount of the polishing wheel during its entire life cycle operation. Usually, the working stroke of the telescopic rod 1213 can be calibrated with the position where the initial value of the specification model of the polishing wheel is located and the preset maximum wear amount as the stroke range of the entire life cycle.

[0066] In some embodiments, one end of the telescopic rod 1213 is fixedly connected to the output shaft of the gearbox 1212, and the other end is a free end. Under the action of the first power source 131, it contacts the limiting member 1215. When the servo motor 1211 rotates, the gearbox 1212 drives the telescopic rod 1213 to move along the first direction, reducing or increasing the distance between the output end of the gearbox 1212 and the limiting member 1215, thereby changing the position of the polishing wheel 111 relative to the roller surface to achieve adjustment.

[0067] After the driving member sets the "zero position" of the telescopic rod 1213, the first moving assembly 130 and the second moving assembly 140 can drive the polishing wheel 111 to quickly move to the initial position for polishing operation. During the subsequent polishing process, the driving member 121 adjusts the position of the polishing wheel 111 in real time according to the operating parameters and model settings (the extended length of the telescopic rod 1213) to achieve position control of the polishing wheel.

[0068] In some embodiments, the monitoring member further includes a first sensor 1218 and a second sensor 1219.

[0069] The first sensor 1218 and the second sensor 1219 are respectively fixedly connected to the extension plate 1217 and are fixedly spaced along the first direction, and are used to detect the maximum stroke and the minimum stroke of the telescopic rod 1213. When the telescopic rod 1213 triggers the first sensor 1218 or the second sensor 1219, the system issues relevant information including alarm information, indicating that the driving member telescopic rod 1213 is in an extreme state, and issues operation prompts such as polishing wheel replacement prompts, and shutdown instructions, etc.

[0070] The first sensor 1218 is fixedly connected to the first moving seat 132 or the second moving seat 142, and the second sensor 1219 is fixedly connected to the first moving seat 132 or the second moving seat 142.

[0071] The first sensor 1218 and the second sensor 1219 are located at two extreme limit positions of the output end of the telescopic rod 1213. When the output end is in one of these two positions, a detected signal is sent to confirm the status information of the polishing wheel 111, including fault handling information, and to issue an instruction set by the program.

[0072] The third power source 112 drives the polishing wheel 111 to rotate. For example, the third power source 112 is a pulley drive structure that drives the polishing wheel 111 to rotate.

[0073] As Figure 4 shown, in the related art, rigid polishing is used to clean the roller surface. When the rigid polishing wheel 111a is under no pressure or small pressure, it is impossible to determine whether there is a polishing contact surface with the workpiece surface. Coupled with the influence of the accuracy, lubrication state, and static friction force of the slide rail moving surface, there is a sliding creep phenomenon under small pressure, and the contact is unstable, or it is only in a line contact state, and a polishing surface cannot be formed. In this case, a relatively large pressure must be applied for the polishing operation. Although, when the pressure is increased, the end of the radially distributed abrasive cloth blades 1112a will form a certain top "arc surface" deformation and can contact the roller surface, but since the abrasive is bonded to the abrasive cloth plane, the true effective working surface (the abrasive grain surface, that is, the plane perpendicular to the rays of the abrasive cloth blades 1112a) does not play its due role, and the greater the force, the easier the abrasive grains are to fall off, and neither the service life of the polishing wheel 111 nor the polishing quality can reach a satisfactory level.

[0074] Currently, most top roller polishing machines for hot-dip galvanized strip lines in China still use polishing machines with rigid polishing wheels 111 with pressure control, and the service life of the polishing wheel 111 is only 15 - 20 days.

[0075] In view of the above problems, as Figure 5 shown, in some embodiments, the polishing wheel 111 of the present application includes a clamping disk 1111 and clamping disk abrasive cloth blades 1112.

[0076] The polishing wheel 111 is a flexible structure polishing wheel. The abrasive cloth blades 1112 of the polishing wheel 111 are arranged and fixed non-radially, and are arranged in an arc shape from the clamping disk 1111 to the outer circumferential surface (the arc direction is opposite to the rotation direction); there is no isolation and fixation between the abrasive cloth blades 1112 outside the diameter of the clamping disk 1111. In this way, the greater the distance between the abrasive cloth blades 1112 and the outer diameter of the clamping disk 1111 in the radial direction, the greater the gap between the abrasive cloth blades 1112. When the polishing wheel 111 is subjected to circumferential force, there is a certain compression space for the abrasive cloth blades 1112 in the outer arc region.

[0077] Under relative zero pressure, due to the centrifugal force of high-speed rotation, the abrasive cloth blade 1112 is in a pressureless state, and the outer diameter of the abrasive cloth blade 1112 has a tendency to increase in the radial direction. Its deformation amount (including the initial small deformation amount) forms a (grinding) polishing surface for the rotating roller surface.

[0078] By performing flexible polishing under position control, the service life of the polishing wheel 111 is extended from the original 15 - 20 days to about 150 - 180 days. It also reduces the grinding dust generated by the polishing wheel 111 during polishing, reduces the load requirement for exhaust dust removal, improves the dust removal effect, improves the environmental conditions in this area, and ensures the production quality of high-end products.
