Description

Technical Field

[0001] The invention relates to the technical field of roller washing, in particular to a roller surface cleaning device. Background Art

[0002] Cold rolls are primarily used in the cold processing of metal materials. They are required to possess high strength, high wear resistance, and good dimensional stability to meet production needs. In the cold roll production process, after casting, rough machining, and heat treatment, the rolls undergo finishing turning, grinding, and then washing. After washing, subsequent surface treatment is performed.

[0003] Among them, a lot of debris will be generated during the finishing turning and grinding process. At the same time, oily coolant will be used in the turning and grinding process. Therefore, the cold rolling roller needs to be cleaned repeatedly to avoid affecting the subsequent surface treatment.

[0004] Most existing surface cleaning devices use immersion cleaning to clean the surface of the cold rolling roller. After long-term cleaning in this way, the cleanliness of the immersion water deteriorates, resulting in inadequate cleaning of the roller and the inability to thoroughly clean the areas with greater dirtiness. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to solve the problem of incomplete cleaning of the surface of the rolling mill, the present invention provides a surface cleaning device for the rolling mill. By providing a flushing mechanism, the effect of multiple flushings in one movement is achieved. By replacing the immersion mode with the flushing mode, the cleanliness level of the cleaning liquid can be ensured to be consistent, and thus the cleanliness level of the continuously cleaned rolling mill can be consistent.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a surface cleaning device for a rolling mill roll, comprising a bottom bed, wherein the length direction of the bottom bed is set as the x-axis, the width direction of the bottom bed is set as the y-axis, and the height direction of the bottom bed is set as the z-axis; a crossbeam arranged along the x-axis is provided above the bottom bed, and a moving mechanism is slidably provided on the crossbeam;

[0007] A flushing mechanism is fixedly installed below the mobile mechanism, and the flushing mechanism includes a housing and multiple groups of cleaning components. The top of the housing is fixedly connected to the mobile mechanism, and the cleaning components are arranged below the housing. The cleaning components are arranged in parallel along the x-axis direction. The multiple groups of cleaning components are connected by support shafts arranged along the x-axis, and the cleaning components are rotatably connected to the support shafts. Both ends of the support shafts are fixedly installed with the housing; connecting seats are provided between adjacent cleaning components, and the connecting seats are sleeved on the support shafts.

[0008] The cleaning assembly includes a J-shaped support arm 1 and a support arm 2, wherein the support arm 1 is arranged opposite to the support arm 2, and the support arm 1 and the support arm 2 are staggered in a scissor-shaped manner on the plane where the y-axis and the z-axis are located, and the support shaft is rotatably connected to the support arm 1 and the support arm 2 respectively; a plurality of nozzle assemblies are slidably installed in the support arm 1 and the support arm 2, and the nozzle assemblies are circumferentially arranged on the plane where the y-axis and the z-axis are located;

[0009] Therefore, the J-shaped support arm 1 and support arm 2 form a scissor-like clamp, and the curved hook part forms a circular adaptation to the end face of the roller; the effect of multiple flushings in one movement is achieved through four groups of cleaning components, and the flushing mode replaces the immersion mode, which can ensure the consistent cleanliness of the cleaning liquid, and thus the consistent cleanliness of the continuously cleaned rollers.

[0010] Furthermore, in order to ensure that the four groups of cleaning components work synchronously, the vertical end of the support arm one is hinged to the connecting frame one, and the vertical end of the support arm two is hinged to the connecting frame two; the other ends of the connecting frame one and the connecting frame two are rotatably connected with a connecting shaft, and the top of the connecting seat is fixedly installed with an electric push rod one, and the movable part of the electric push rod one is sleeved on the connecting shaft; thus, the electric push rod one controls the connecting shaft to move along the z-axis direction, thereby realizing the change of the angle between the connecting frame one and the connecting frame two, and then realizing the opening and closing of the support arm one and the support arm two, so that the flushing mechanism can be spliced ​​from top to bottom at the end face, thereby realizing rapid assembly.

[0011] Furthermore, in order to realize the placement and sliding of the nozzle assembly; an arc plate is fixedly installed between the support shafts, and the arc plate, the hook portion of support arm one and the hook portion of support arm two form a circle; the arc plate, the hook portion of support arm one and the hook portion of support arm two are all fixedly installed with a placement seat, and a plurality of transmission assemblies are rotatably installed on the top of the placement seat, and the transmission assemblies are arranged circumferentially, and adjacent transmission assemblies are connected by synchronous belts; a plurality of rack plates are slidably installed on the top of the placement seat, and the rack plates are meshed with the transmission assemblies one by one; the long sides of the rack plates are arranged radially; the nozzle assembly is fixedly installed on the rack plate; a micro motor is fixedly installed at the arc plate, and a driving wheel is provided at the output end of the micro motor, and the driving wheel is meshed with one of the transmission assemblies; thereby, multiple transmission assemblies rotate simultaneously, thereby controlling multiple rack plates to move radially at the same time, thereby realizing synchronous regulation of the distance between multiple nozzle assemblies and the roller surface.

[0012] Furthermore, the transmission assembly includes a rotating shaft, a gear is fixedly mounted on the rotating shaft, a synchronous wheel is provided on the rotating shaft, and the gear, synchronous wheel and the rotating shaft are coaxially arranged; one end of the rotating shaft is rotatably connected to the mounting seat, and the tooth surface of the gear is engaged with the rack plate; the side surface of the synchronous wheel is engaged with the synchronous belt; thus, the transmission assemblies achieve the same-direction rotation through the engagement of the synchronous wheel with the synchronous belt, and then the rack plate is controlled to move in the same direction through the gear.

[0013] Furthermore, the nozzle assembly includes a pressure regulating valve, a connecting part, and a nozzle head; one end of the pressure regulating valve is fixedly connected to the connecting part, and the other end of the connecting part is slidably connected to the nozzle head, and the connecting part and the nozzle head adopt a dynamic seal; a mounting seat is provided on the top of the rack plate, and the mounting seat is sleeved on the pressure regulating valve; a conical groove is provided at one end of the nozzle head away from the connecting part; thus, after the water flows through the pressure regulating valve, the connecting part and the nozzle head in sequence, it hits the arc surface of the conical groove from the nozzle head port to realize a fan-shaped spray shape.

[0014] Furthermore, in order to adjust the flushing water width of the nozzle assembly in real time, an electric push rod 2 is provided on the mounting seat, and the axis of the electric push rod 2 is arranged parallel to the length of the rack plate; the movable part of the electric push rod 2 is fixedly connected to the nozzle head; a displacement sensor is also provided on the rack plate; thus, when the rack plate moves outward, the displacement sensor transmits a signal to the control center, and the control center controls the extension of the electric push rod 2 through the signal, thereby opening the distance between the nozzle head and the connecting part; and then when the distance between the nozzle assembly and the roller body changes, the flow rate of the nozzle assembly is adjusted in real time, thereby changing the width of the water flushing and avoiding water waste.

[0015] Furthermore, in order to adjust the water flow rate, an end plate 1 is fixedly mounted on the end of the connecting portion away from the pressure regulating valve, and a plurality of circumferential through holes are formed on the end plate 1; an inner tube is fixedly mounted in the center of the end plate 1, and the inner tube is coaxially arranged with the connecting portion; a mixing chamber and a liquid outlet are formed inside the nozzle head; the mixing chamber and the liquid outlet are connected to the conical groove and are coaxially arranged;

[0016] An end plate 2 is fixedly installed at the mixing chamber, and a plurality of protrusions are arranged on the circumferential direction of the end plate 2, and the protrusions correspond to the through holes one by one, and the protrusions and the through holes are embedded in each other; a plurality of flow grooves are opened on the circumferential direction of the end plate 2, and the flow grooves and the protrusions are arranged in an alternating manner; thus, when the end plate 1 and the end plate 2 are engaged, the protrusions close the through holes, so that the water flows into the mixing chamber only through the inner tube; when the end plate 1 and the end plate 2 are separated, the protrusions are separated from the through holes, so that the water flows into the mixing chamber through the through holes of the inner tube; thereby realizing the switching of the water flow rate, and then changing the width of the sprayed water flow.

[0017] Furthermore, the protrusion is cylindrical, and the height of the protrusion increases from the inside to the outside; thus, due to the cylindrical protrusions of different heights, gradient flow rate switching is achieved.

[0018] Furthermore, the protrusion is hemispherical, and the radius of the protrusion increases from the inside to the outside, and the radius of the through hole increases from the inside to the outside; due to the cylindrical protrusions with different radii, gradient flow rate switching is achieved.

[0019] Furthermore, the moving mechanism includes a control box, a sliding group, and a rope extension group; the sliding group adopts an inverted pulley assembly, and the rope extension group adopts an electric extension rod based on rope traction; a stepper motor and an AC motor are provided in the control box, and the AC motor is used to control the rope extension group. The output end of the stepper motor is provided with a control wheel, and the control wheel is located at the top of the control box, and the bottom of the beam is provided with teeth distributed at equal distances along the x-axis; the control wheel is engaged with the teeth; the control box is moved back and forth in the air by engaging the teeth of the control wheel, and the sliding group assists in sliding.

[0020] Furthermore, a diverter valve, pipeline 1, and pipeline 2 are provided inside the housing. The diverter valves correspond to the cleaning components one by one, and the output ends of the diverter valves are connected to the cleaning components through pipelines; the input ends of three of the diverter valves are connected to the branch ends of pipeline 1, and the input end of another diverter valve is connected to one end of pipeline 2; both ends of pipeline 1 are connected to a water tank, and pipeline 1 is provided with an air-controlled one-way valve; the other end of pipeline 2 is connected to a pre-wash liquid tank, and pipeline 2 is also provided with an air-controlled one-way valve;

[0021] The water tank provides clean water for the flushing mechanism, and the pre-wash liquid tank provides pre-wash liquid for the flushing mechanism; thus, the flushing mechanism moves from the end of the roller close to the origin, and the pre-wash liquid preferentially flows out from the cleaning assembly located in the front, and all the nozzle assemblies here work to spray the pre-wash liquid on the roller body in the form of foam; then, the low-position nozzle assembly of the second cleaning assembly, the middle-position nozzle assembly of the third cleaning assembly, and the high-position nozzle assembly of the fourth cleaning assembly spray clean water for flushing.

[0022] Furthermore, a support frame is fixedly installed on the top of the control box, and the support frame is vertically arranged. An auxiliary group is fixedly installed on the top of the support frame, and the auxiliary group includes two rollers arranged in parallel; two slide grooves are opened on both sides of the vertical part of the beam; an air pipeline is arranged in the slide groove; the rollers correspond to the slide grooves one by one, and the rollers roll in the corresponding slide grooves, and the air pipeline is located between the rollers and the beam; thus, when the control box moves, the rollers follow the movement, thereby squeezing the air pipeline.

[0023] Furthermore, both ends of one of the air tubes are connected to the air-controlled one-way valve on pipeline one, and one end of the other air tube is connected to the air-controlled one-way valve on pipeline two; thus, the roller moves to squeeze the air tube, controlling the corresponding air-controlled one-way valve to open.

[0024] Furthermore, an output end of the diverter valve connected to the pipeline 1 is provided with an electromagnetic reversing valve, and a liquid outlet of the electromagnetic reversing valve is connected to the pipeline of the support arm 1 or the support arm 2;

[0025] The electromagnetic reversing valve is provided with an input port a, an input port b, an output port e, an output port f and an output port g; the output port e is connected to the high-position nozzle assembly pipeline of support arm one or support arm two, the output port f is connected to the mid-position nozzle assembly pipeline of support arm one or support arm two, and the output port g is connected to the low-position nozzle assembly pipeline of support arm one or support arm two, and the input port a and input port b are connected to the output end of the diverter valve through a pipeline; thus, the electromagnetic reversing valve receives an instruction to allow clean water to flow in from the input port b and then flow out from the output port g to the low-position nozzle assembly of the second station, or to flow in from the input port b and then flow out from the output port f to the mid-position nozzle assembly, Or clean water flows in from the input port a and then flows out from the output port e to the high-position nozzle assembly; the cleaning components are the first station, the second station, the third station, the fourth station... the nth station from right to left along the x-axis. When the flushing mechanism moves from left to right along the x-axis, the nozzle assembly at the first station sprays foamy pre-cleaning liquid to cover the surface of the roller, and then the low-position nozzle assembly at the second station discharges water, and the water level increases from the second station, and water is discharged from the high-position nozzle assembly at the nth station; when the flushing mechanism moves from right to left along the x-axis, water is discharged from the low-position nozzle assembly at the nth station, and the water level increases from the nth station, and water is discharged from the high-position nozzle assembly at the second station.

[0026] The beneficial effect of the present invention is that the surface cleaning device for the rolling mill of the present invention is provided with multiple groups of cleaning components and a cleaning system, and multiple flushing can be achieved by one movement through the multiple groups of cleaning components. Flushing from bottom to top can use the impact force of the water flow to remove the stains at one time, and avoid the upper water flow from carrying away the lower pre-wash liquid, thereby improving the cleaning effect; in addition, after the lower part is flushed, the water flow flowing down from the upper part cleans the lower part again, and repeated flushing can make the roller body cleaner.

[0027] The surface cleaning device for the roller is provided with a transmission assembly and a rack plate. The multiple transmission assemblies rotate simultaneously, thereby controlling the multiple rack plates to move radially at the same time, thereby realizing the synchronous regulation of the distance between the multiple nozzle assemblies and the roller surface.

[0028] The surface cleaning device for a rolling mill roller is provided with a nozzle head and a connecting part. When the end plate 1 of the connecting part is engaged with the end plate 2 of the nozzle head, the protrusion closes the through hole, so that the water flows into the mixing chamber only through the inner tube; the end plate 1 and the end plate 2 are separated, and the protrusion is separated from the through hole, so that the water flows into the mixing chamber through the through hole of the inner tube; thereby realizing the switching of the water flow rate and changing the width of the sprayed water flow.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0048] Example 1:

[0049] Reference Figures 1-8 and Figure 13 A roller surface cleaning device includes a bottom bed 1, wherein the length direction of the bottom bed 1 is set as the x-axis, the width direction of the bottom bed 1 is set as the y-axis, and the height direction of the bottom bed 1 is set as the z-axis (refer to Figure 1A crossbeam 21 is provided above the bottom bed 1 along the x-axis, a movable mechanism 3 is slidably provided on the crossbeam 21, and the crossbeam 21 is an I-shaped structure. A vertical frame 2 is fixedly installed on the top of the bottom bed 1, and the crossbeam 21 is provided on the top of the vertical frame 2; two fixed seats 12 are slidably provided on the top of the bottom bed 1 through a movable groove 11, and the two fixed seats 12 are used to place the rollers 5, and the rollers 5 are located below the movable mechanism 3;

[0050] Reference Figures 1-5 A flushing mechanism 4 is fixedly installed below the moving mechanism 3. The flushing mechanism 4 includes a casing 41 and four groups of cleaning components 42. The top of the casing 41 is fixedly connected to the moving mechanism 3. The cleaning components 42 are arranged below the casing 41. The cleaning components 42 are arranged in parallel along the x-axis direction. The four groups of cleaning components 42 are connected by a support shaft 442 arranged along the x-axis, and the cleaning components 42 are rotatably connected to the support shaft 442. Both ends of the support shaft 442 are fixedly installed with the casing 41; a connecting seat 441 is provided between adjacent cleaning components 42, and the connecting seat 441 is sleeved on the support shaft 442;

[0051] Reference Figure 3 、 Figure 4 The cleaning assembly 42 includes two J-shaped support arms 1 421 and two J-shaped support arms 2 422. Figure 4 It can be seen that the two support arms 421 are arranged in parallel to form the right washing arm, and the two support arms 422 are arranged in parallel to form the left washing arm. The inner spacing of the right washing arm is larger than the inner spacing of the left washing arm. The vertical end of the support arm 422 passes through the inner side of the support arm 421, thereby forming a staggered state). The right washing arm and the left washing arm are arranged opposite to each other. On the plane where the y-axis and the z-axis are located, the vertical end of the left washing arm passes through the inner side of the right washing arm, so that the right washing arm and the left washing arm are staggered to form a scissors-shaped arrangement. Two support shafts 442 are provided, which are rotatably connected to the right washing arm and the left washing arm respectively; a plurality of nozzle assemblies are slidably installed in the right washing arm and the left washing arm, and the nozzle assemblies are circumferentially arranged on the plane where the y-axis and the z-axis are located.

[0052] Among them: reference Figure 3 、 Figure 5 In order to ensure that the four groups of cleaning components 42 work synchronously, the vertical end of the right cleaning arm is hinged with a connecting frame 1 431, and the vertical end of the left cleaning arm is hinged with a connecting frame 2 432; the other ends of the connecting frame 1 431 and the connecting frame 2 432 are rotatably connected with a connecting shaft 444, and the top of the connecting seat 441 is fixedly installed with an electric push rod 1 443, and the movable part of the electric push rod 1 443 is sleeved on the connecting shaft 444; thus, the electric push rod 1 443 controls the connecting shaft 444 to move along the z-axis direction, thereby realizing the change of the angle between the connecting frame 1 431 and the connecting frame 2 432, and then realizing the opening and closing of the right cleaning arm and the left cleaning arm, which is convenient for the end face splicing of the flushing mechanism 4 from top to bottom to achieve quick assembly.

[0053] Reference Figure 8 The nozzle assembly includes a pressure regulating valve 71, a connecting part 72, and a nozzle head 73; one end of the pressure regulating valve 71 is fixedly connected to the connecting part 72, and the other end of the connecting part 72 is slidably connected to the nozzle head 73, and the connecting part 72 and the nozzle head 73 adopt a dynamic seal; a mounting seat is provided on the top of the rack plate 453, and the mounting seat is sleeved on the pressure regulating valve 71; a conical groove 733 is provided at one end of the nozzle head 73 away from the connecting part 72; thus, after the water flows through the pressure regulating valve 71, the connecting part 72 and the nozzle head 73 in sequence, it hits the arc surface of the conical groove 733 from the port of the nozzle head 73 to realize a fan-shaped spray shape.

[0054] Reference Figure 13 The moving mechanism 3 includes a control box 31, a sliding group 32, and a rope extension group 34; the sliding group 32 adopts an inverted pulley assembly, and the rope extension group 34 adopts an electric extension rod based on rope traction; a stepper motor and an AC motor are provided in the control box 31, and the AC motor is used to control the rope extension group 34. The output end of the stepper motor is provided with a control wheel, which is located at the top of the control box 31. The bottom of the crossbeam 21 is provided with teeth distributed at equal distances along the x-axis, and the control wheel is engaged with the teeth; the control box 31 is reciprocated in the air by meshing the teeth of the control wheel, and the sliding group 32 assists in sliding.

[0055] The working process is as follows: the fixed seat 12 drives the roller 5 to move to the bottom of the moving mechanism 3, and the AC motor controls the rope extension group 34 to extend, so that the flushing mechanism 4 is close to the roller 5; at this time, the electric push rod 1 443 is controlled to shrink, driving the connecting shaft 444 to move downward, and the connecting frame 1 431 and the connecting frame 2 432 push the support arm 1 421 and the support arm 2 422 outward; when the roller 5 reaches the appropriate position of the flushing mechanism 4, the electric push rod 1 443 is controlled to extend, and the connecting shaft 444 controls the connecting frame 1 431 and the connecting frame 2 432 moves inward, pulling down support arm 1 421 and support arm 2 422 to close, so that the circle formed by the hook portion is coaxial with the roller 5 (the diameter of the circle formed by the cleaning component 42 is always much larger than the maximum diameter of the roller 5); then the moving mechanism 3 moves from the origin along the x-axis (i.e., moves from left to right along the x-axis), and the nozzle assemblies at the four groups of cleaning components 42 spray cleaning liquid inward. When the moving mechanism 3 returns, the nozzle assemblies at the four groups of cleaning components 42 spray clean water inward; thereby achieving two repeated cleanings, thereby improving the cleaning effect.

[0056] Example 2: Figures 3-7 As shown, in order to adapt to the special-shaped roller (the working surface is composed of multiple cylindrical segments with different diameters), the nozzle assembly needs to adjust its position in real time to ensure that the roller surface is subjected to a consistent impact force. Therefore, in order to achieve the placement and synchronous sliding of the nozzle assembly, the following are added on the basis of Example 1:

[0057] Reference Figures 3-6, an arc-shaped plate 423 is fixedly installed between the support shafts 442, and the arc-shaped plate 423, the hook portion of the support arm 1 421 and the hook portion of the support arm 2 422 form a circle; the arc-shaped plate 423, the hook portion of the support arm 1 421 and the hook portion of the support arm 2 422 are all fixedly installed with a placement seat 451, and a plurality of transmission components 452 are rotatably installed on the top of the placement seat 451. The transmission components 452 are arranged circumferentially, and adjacent transmission components 452 are connected by synchronous belts; a plurality of rack plates are slidably installed on the top of the placement seat 451 453, the rack plate 453 is meshed with the transmission assembly 452 in a one-to-one correspondence; the long side of the rack plate 453 is arranged radially; the nozzle assembly is fixedly mounted on the rack plate 453; a micro motor is fixedly mounted on the arc plate 423, and a driving wheel 454 is provided at the output end of the micro motor, which is meshed with one of the transmission assemblies 452; thereby, multiple transmission assemblies 452 rotate at the same time, thereby controlling multiple rack plates 453 to move radially at the same time; thus, multiple nozzle assemblies are synchronously regulated to adjust the distance between them and the surface of the roller 5.

[0058] Reference Figure 7 The transmission assembly 452 includes a rotating shaft 4521, on which a gear 4522 is fixedly mounted, and a synchronous wheel 4523 is provided on the rotating shaft 4521. The gear 4522 and the synchronous wheel 4523 are coaxially arranged with the rotating shaft 4521; one end of the rotating shaft 4521 is rotatably connected to the mounting seat 451, and the tooth surface of the gear 4522 is engaged with the rack plate 453; the side surface of the synchronous wheel 4523 is engaged with the synchronous belt; thus, the transmission assemblies 452 rotate in the same direction through the synchronous wheel 4523 engaging the synchronous belt, and then the rack plate 453 is controlled to move in the same direction through the gear 4522.

[0059] The working process is as follows: when the roller 5 is a special-shaped roller (such as an X-shaped roller body), the control center inputs the cleaning axis length, each end face diameter and thickness data of the special-shaped roller in advance to obtain the moving path of the flushing point; then the transmission component 452 is controlled by the micro motor to make the rack plate 453 move synchronously, so that the nozzle assembly on the corresponding cleaning component 42 moves radially, so that the flushing force is consistent, thereby improving the cleaning force of the roller 5.

[0060] Example 3: As the distance between the nozzle assembly and the roller body changes, the flushing area will also change accordingly. In order to avoid wasting water resources, Figures 8-11 As shown, based on the second embodiment, the following is added:

[0061] Reference Figure 8 、 Figure 9, an electric push rod 2 74 is provided on the mounting seat, and the axis of the electric push rod 2 74 is arranged parallel to the length of the rack plate 453; the movable part of the electric push rod 2 74 is fixedly connected to the nozzle head 73; a displacement sensor is also provided on the rack plate 453; thus, when the rack plate 453 moves outward, the displacement sensor transmits a signal to the control center, and the control center controls the electric push rod 2 74 to extend through the signal, thereby opening the distance between the nozzle head 73 and the connecting part 72; and then, when the distance between the nozzle assembly and the roller body changes, the flow rate of the nozzle assembly is adjusted in real time, thereby changing the width of the water flushing and avoiding water waste.

[0062] Among them: reference Figure 9 An end plate 721 is fixedly mounted on one end of the connecting portion 72 away from the pressure regulating valve 71, and a plurality of circumferential through holes 7211 are formed on the end plate 721; an inner tube 722 is fixedly mounted in the center of the end plate 721, and the inner tube 722 is coaxially arranged with the connecting portion 72; a mixing chamber 731 and a liquid outlet 732 are formed inside the nozzle head 73; the mixing chamber 731, the liquid outlet 732 and the conical groove 733 are connected and coaxially arranged;

[0063] An end plate 2 734 is fixedly installed at the mixing chamber 731, and a plurality of protrusions 7341 are arranged circumferentially on the end plate 2 734, and the protrusions 7341 correspond to the through holes 7211 one by one, and the protrusions 7341 and the through holes 7211 are embedded in each other; a plurality of flow grooves 7342 are opened circumferentially on the end plate 2 734, and the flow grooves 7342 and the protrusions 7341 are arranged alternately; thus, when the end plate 1 721 and the end plate 2 734 are engaged, the protrusions 7341 close the through holes 7211, so that the water flows into the mixing chamber 731 only through the inner tube 722; when the end plate 1 721 and the end plate 2 734 are separated, the protrusions 7341 are separated from the through holes 7211, so that the water flows into the mixing chamber 731 through the through holes 7211 of the inner tube 722; thereby realizing the switching of the water flow rate, and then changing the width of the sprayed water flow.

[0064] Reference Figure 10 、 Figure 11 ; The protrusion 7341 is hemispherical, and the radius of the protrusion 7341 increases from the inside to the outside, and the radius of the through hole 7211 increases from the inside to the outside; due to the cylindrical protrusion 7341 with different radii, gradient flow rate switching is achieved.

[0065] The working process is as follows: the displacement sensor senses the rack plate 453 approaching or moving away from the roller 5, and transmits the displacement data to the control center for processing, and then the control center controls the electric push rod 2 74 to work;

[0066] When the rack plate 453 approaches the roller 5, the second electric push rod 74 contracts, causing the nozzle head 73 to move closer to the connecting portion 72, so that the protrusion 7341 is embedded in the through hole 7211, and the water flows out only from the inner tube 722;

[0067] When the rack plate 453 moves away from the roller 5, the electric push rod 2 74 extends, causing the nozzle head 73 to slide away from the connecting part 72, and the protrusion 7341 separates from the through hole 7211. The protrusions 7341 with different radii make the flow rate proportional to the extension length of the electric push rod 2 74.

[0068] Example 4: The difference from Example 3 is: Figure 12 The protrusion 7341 is cylindrical, and the height of the protrusion 7341 increases from the inside to the outside; thus, due to the cylindrical protrusions 7341 of different heights, gradient flow rate switching is achieved.

[0069] Example 5: Figures 14-16 In order to improve the cleaning power, the following steps are added based on Example 3:

[0070] Reference Figure 15 , four diverter valves, pipeline 1 and pipeline 2 are provided inside the casing 41, the diverter valves correspond to the cleaning components 42 one by one, and the output end of the diverter valve is connected to the cleaning component 42 through a pipeline; the cleaning component 42 is the first station, the second station, the third station and the fourth station from right to left along the x-axis, wherein the input ends of the diverter valves corresponding to the second station, the third station and the fourth station are connected to the branch end of pipeline 1, and the input end of the diverter valve corresponding to the first station is connected to one end of pipeline 2; both ends of pipeline 1 are connected to a water cylinder 61, and an air-controlled one-way valve 63 and a hydraulic pump are provided on pipeline 1; the other end of pipeline 2 is connected to a pre-wash liquid cylinder 62, and an air-controlled one-way valve 63 and a hydraulic pump are also provided on pipeline 2;

[0071] The water tank 61 provides clean water to the flushing mechanism 4, and the pre-washing liquid tank 62 provides pre-washing liquid to the flushing mechanism 4; thus, the flushing mechanism 4 moves from the end of the roller 5 close to the origin, and the pre-washing liquid preferentially flows out from the cleaning component 42 of the first station, and all the nozzle components here work to spray the pre-washing liquid on the roller body in the form of foam; then, the low-position nozzle assembly at the second station, the middle-position nozzle assembly at the third station, and the high-position nozzle assembly at the fourth station discharge water at the same time.

[0072] Reference Figure 14 A support frame 311 is fixedly installed on the top of the control box 31, and the support frame 311 is arranged vertically. An auxiliary group 33 is fixedly installed on the top of the support frame 311, and the auxiliary group 33 includes two rollers 331 arranged in parallel; two slide grooves 211 are opened on both sides of the vertical part of the beam 21; an air pipe 212 is arranged in the slide groove 211; the rollers 331 correspond to the slide grooves 211 one by one, and the rollers 331 roll in the corresponding slide grooves 211, and the air pipe 212 is located between the rollers 331 and the beam 21; therefore, when the control box 31 moves, the rollers 331 follow the movement, thereby squeezing the air pipe 212.

[0073] Both ends of one of the air tubes are connected to the air-controlled one-way valve 63 on pipeline one, and one end of the other air tube is connected to the air-controlled one-way valve 63 on pipeline two; thus, the roller 331 moves to squeeze the air tube, controlling the corresponding air-controlled one-way valve 63 to open.

[0074] Reference Figure 16 The output end of the diverter valve corresponding to the second station, the third station, and the fourth station is provided with an electromagnetic reversing valve 46, and the liquid outlet 732 of the electromagnetic reversing valve 46 is connected to the support arm 1 421 or the support arm 2 422 pipeline;

[0075] The electromagnetic reversing valve 46 is provided with an input port a, an input port b, an output port e, an output port f and an output port g; the output port e is connected to the high-position nozzle assembly pipeline of the support arm 1 421 or the support arm 2 422, the output port f is connected to the mid-position nozzle assembly pipeline of the support arm 1 421 or the support arm 2 422, the output port g is connected to the low-position nozzle assembly pipeline of the support arm 1 421 or the support arm 2 422, and the input port a and the input port b are connected to the output end of the diverter valve through the pipeline; thus, the electromagnetic reversing valve 46 receives an instruction to allow clean water to flow in from the input port b and then flow out from the output port g to the low-position nozzle assembly of the second workstation, or clean water to flow in from the input port b and then flow out from the output port f to the mid-position nozzle assembly, or clean water to flow in from the input port a and then flow out from the output port e to the high-position nozzle assembly.

[0076] The working process is as follows: when the moving mechanism 3 moves from the origin along the x-axis (ie, moves from left to right along the x-axis), the roller 331 moves to the right (refer to Figure 15 ) Squeeze the air line 212, open the air-controlled one-way valve 63 at the water cylinder 61 and the pre-wash liquid cylinder 62 on the right, and the pre-wash liquid in the pre-wash liquid cylinder 62 will flow out from the cleaning assembly 42 of the first station first. The nozzle assemblies here all work to spray the pre-wash liquid on the roller body in the form of foam; then, the low-position nozzle assembly of the second station, the middle-position nozzle assembly of the third station, and the high-position nozzle assembly of the fourth station spray clean water for flushing, thereby realizing progressive flushing of the roller 5 from low to high, and flushing from bottom to top can use the impact force of the water flow to carry away the stains at one time, and avoid the upper water flow carrying away the lower pre-wash liquid, thereby improving the cleaning effect; in addition, after the lower part is flushed, the water flow flowing down from the upper part cleans the lower part again, and repeated flushing can make the roller body cleaner.
