Description

Technical Field

[0001] This application relates to the field of aluminum foil embossing technology, and in particular to a concentricity detection and grinding device for an embossing roller. Background Art

[0002] During the production process of aluminum foil paper, an embossing roller is required to emboss the aluminum foil paper so that patterns are formed on the surface of the aluminum foil paper to meet the packaging requirements. Generally, an embossing is carried out by using a pressure roller and an embossing roller. The aluminum foil paper is conveyed through the pressure roller and the embossing roller. Through extrusion between the embossing roller and the pressure roller, the pattern on the embossing roller can be imprinted on the aluminum foil paper.

[0003] Since the pressure roller and the embossing roller apply thrust at both ends of the roller, the extrusion force on the aluminum foil will weaken in the middle of the embossing roller and the pressure roller due to the relatively long distance from the force application points. Therefore, the diameters of the embossing roller and the pressure roller need to gradually increase from both ends to the middle, making the middle of the roller slightly convex to adapt to the forces at both ends of the roller body and ensure the embossing effect on the aluminum foil paper.

[0004] Currently, the pressure roller is usually made of a wool roller or a nylon roller. After being used for a period of time, due to extrusion and friction, wear and deformation will occur, causing a change in the concentricity of the pressure roller, resulting in the rotation of the pressure roller being jerky. And because the amount of deformation of the pressure roller is small, it is difficult for workers to observe the jerk of the pressure roller with the naked eye. If the pressure roller is not processed in time with sandpaper, it will lead to a deviation in the concentricity of the pressure roller and a decrease in the quality of aluminum foil embossing, ultimately affecting the embossing effect of the aluminum foil paper. Summary of the Invention

[0005] In order to improve the problem that it is difficult to observe the deviation of the concentricity of the embossing roller and affect the embossing effect, this application provides a concentricity detection and grinding device for an embossing roller.

[0006] The concentricity detection and grinding device for an embossing roller provided by this application adopts the following technical solutions: A concentricity detection and grinding device for an embossing roller includes a bracket, a guide rail, a distance measuring instrument, a control panel, a driving mechanism, and a grinding mechanism. The bracket is arranged on the frame of the embossing roller. The guide rail is arranged on the bracket along the length direction of the embossing roller. The distance measuring instrument is slidably arranged on the guide rail and is used to measure the distance from the embossing roller. The control panel is arranged on the bracket and is electrically connected to the distance measuring instrument. The driving mechanism is arranged on the bracket and is used to drive the distance measuring instrument to slide. The grinding mechanism is arranged on the guide rail and is used to grind the embossing roller.

[0007] By adopting the above technical solution, during the embossing process of the embossing roller, the driving mechanism drives the distance measuring instrument to reciprocate along the length direction of the embossing roller on the track. During the movement of the distance measuring instrument, the distance between the distance measuring instrument and the embossing roller is measured. If the embossing roller is worn or deformed, the distance measuring instrument can measure the distance between the outer circumference at the same radial position of the embossing roller and the distance measuring instrument. If the fluctuation range of the measured distance difference exceeds the set value, the grinding mechanism can timely grind the worn or deformed position of the embossing roller, improving the problem that it is difficult to observe the deviation of the concentricity of the embossing roller and affecting the embossing effect.

[0008] Optionally, the grinding mechanism includes a driving seat, a grinding wheel machine and a control component. The driving seat is slidably arranged on the guide rail. The grinding wheel machine is slidably arranged on the driving seat in the direction towards the embossing roller. The grinding wheel machine is electrically connected to the control panel. The control component is arranged on the bracket and is used to drive the driving seat and the grinding wheel machine to slide.

[0009] By adopting the above technical solution, the control component drives the driving seat to move on the guide rail, so that the driving seat drives the grinding wheel machine to move to align with the position to be ground on the embossing roller. Then, the control component drives the grinding wheel machine to move in the direction towards the embossing roller, so that the grinding wheel of the grinding wheel machine abuts against the embossing roller. The control panel controls the grinding wheel machine to start, and the grinding wheel machine can grind the worn or deformed part of the embossing roller, thus conveniently and quickly precisely repairing the embossing roller.

[0010] Optionally, the control component includes a control motor, a control lead screw and a control cylinder. The control motor is arranged on the bracket and is electrically connected to the control panel.

The control cylinder is arranged on the driving seat and is electrically connected to the control panel. The piston rod of the control cylinder is connected to the grinding wheel machine.

[0011] By adopting the above technical solution, the control panel drives the control motor to start. The output shaft of the control motor drives the control lead screw to rotate forward or backward. The control lead screw can drive the driving seat to move along the length direction of the guide rail on the guide rail. The piston rod of the control cylinder extends and retracts, and can drive the grinding wheel machine to move on the driving seat in the direction towards the embossing roller, thereby controlling the positions of the driving seat and the grinding wheel machine.

[0012] Optionally, a pressure sensor for detecting the abutting force between the grinding wheel machine and the embossing roller is arranged on the grinding wheel machine. The piston rod of the control cylinder is arranged on the pressure sensor. The pressure sensor is electrically connected to the control panel.

[0013] By adopting the above technical solution, when the piston rod of the cylinder is extended to drive the grinding wheel to abut against the embossing roller, the pressure sensor detects the pressure applied to the grinding wheel and transmits the detected data to the control panel, facilitating the staff to control the acting force of the grinding wheel against the embossing roller, and then accurately controlling the grinding depth of the grinding wheel for grinding the embossing roller.

[0014] Optionally, a cleaning mechanism for cleaning the embossing roller is provided on the driving seat. The cleaning mechanism includes a spraying component, a dust suction component and a drying component. The spraying component is arranged on the driving seat and is used for spraying water on the embossing roller. The dust suction component is arranged on the driving seat and is used for sucking away dust. The drying component is arranged on the driving seat and is used for drying the embossing roller.

[0015] By adopting the above technical solution, when the grinding wheel grinds the embossing roller, the spraying component sprays water on the embossing roller, reducing the temperature of the embossing roller and the friction between the embossing roller and the grinding wheel during the grinding process, thereby improving the grinding effect on the embossing roller. At the same time, it can also reduce the generation of dust during the grinding process. The dust suction component is used to suck away the dust during the grinding process, reducing the amount of dust adhered to other positions of the embossing roller. After grinding, the drying component dries the embossing roller, and the embossing roller can continue the embossing work, reducing the impact on the processing efficiency of the embossing roller.

[0016] Optionally, the spraying component includes a water tank, a water pump and an atomizing nozzle. The water tank is arranged on the bracket. The water pump is connected to the water tank in a communicating manner. The water pump is electrically connected to the control panel. The atomizing nozzle is arranged on the driving seat and is communicated with the water pump. The atomizing nozzle faces the embossing roller.

[0017] By adopting the above technical solution, the control panel controls the water pump to start. The water pump pumps the water in the water tank to the atomizing nozzle, and the atomizing nozzle can spray the water atomically onto the embossing roller, reducing the possibility of the water being concentrated and sprayed onto a local area of the embossing roller, and improving the uniformity of spraying on the grinding area of the embossing roller.

[0018] Optionally, a treatment mechanism for wiping the embossing roller is provided on the driving seat.

A plurality of buffer springs are arranged on the carrier. The support plate is arranged on the plurality of buffer springs. The wiping cloth is detachably arranged on the support plate. The pushing member is arranged on the driving seat and is used for driving the carrier to slide towards the embossing roller.

[0019] By adopting the above technical solution, after grinding is completed, the propulsion member drives the carrier to move toward the direction close to the embossing roller, and the carrier drives the support plate to move, so that the wiping cloth abuts against the embossing roller, and then drives the carrier from one side of the embossing roller to the other side through the driving seat. During the movement, the buffer spring expands and contracts with different diameters of the embossing roller, so that the wiping cloth can always abut against the embossing roller, so that the embossing roller can be cleaned, thereby improving the cleanliness of the embossing roller after grinding and ensuring the subsequent printing effect.

[0020] Optionally, the support plate includes a plurality of arcuate bars, which are hinged in sequence to form an arc shape, and the arcuate bars are arranged on a buffer spring, which always has a tendency to drive the arcuate bars to move toward the center of the plurality of arcuate bars.

[0021] By adopting the above technical solution, the buffer spring drives the multiple arc strips to move in the direction close to the center of the circle of the multiple arc strips, so that the angles between adjacent arc strips can be converted, so that the multiple arc strips drive the wiping cloth to fit the embossing roller, adapt to the outer walls of different diameters at different radial positions of the embossing roller, improve the fit between the wiping cloth and the embossing roller on the support plate, and improve the cleaning effect and efficiency of the embossing roller.

[0022] Optionally, a contraction assembly for driving the multiple arc bars to rotate toward the center of the multiple arc bars is provided on the carrier frame, and the contraction assembly includes a support rod, a support sleeve, an electric push rod and an electromagnet. The support rod is hinged on the arc bar, the support rod is slidably inserted on the support sleeve, the support sleeve is arranged on the carrier frame, the electric push rod is arranged on the inner wall of the support sleeve, and the electromagnet is arranged on the piston rod of the electric push rod and is used to adsorb the support rod.

[0023] By adopting the above technical solution, when it is necessary to grind the embossing roller over a large area, the staff will replace the wiping cloth on the support plate with sandpaper, and then drive the support plate to drive the sandpaper to fit onto the embossing roller. The embossing roller can be grinded over a large area during the rotation of the embossing roller. During the grinding process, the electromagnet is turned on to make the electromagnet adsorbed onto the support rod, and then the piston rod of the electric push rod is controlled to extend. The electric push rod can drive the support rod to extend, so that the arc strip rotates in the direction close to the center of the circle of multiple arc strips, thereby making the multiple arc strips drive the sandpaper to fit stably on the embossing roller, thereby ensuring the accuracy of the grinding of the embossing roller. In addition, the piston rod of the electric push rod can be controlled to extend to drive the arc strip to rotate, and the multiple arc strips can be adjusted to adapt to the outer wall of the embossing roller at different diameters, thereby meeting the requirements for accurate grinding of the embossing roller at different diameters.

[0024] Optionally, a positioning component for positioning the wiping cloth is arranged on the arc-shaped strip. The positioning component includes a positioning bolt and a suction cup. The positioning bolt passes through the wiping cloth and is threadedly arranged on the side of the arc-shaped strip away from the center of the circle, and the suction cup is arranged on the side of the arc-shaped strip facing the center of the circle.

[0025] By adopting the above technical solution, after the staff drives the wiping cloth to be tensioned and attached to a plurality of arc-shaped strips, the positioning bolt is passed through the wiping cloth and threadedly installed on the side of the arc-shaped strip away from the center of the circle. At the same time, the wiping cloth is sucked tightly by the suction cup, so that the wiping cloth can be flatly attached to the plurality of arc-shaped strips, improving the fitting degree of the wiping cloth on the arc-shaped strips.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. If the embossing roller is worn or deformed, the distance measuring instrument can measure the distance between the outer circumference of the embossing roller at the same radial position and the distance measuring instrument. If the fluctuation range of the measured distance difference exceeds the set value, the grinding mechanism can timely grind the worn or deformed position of the embossing roller, improving the problem that it is difficult to observe after the concentricity of the embossing roller deviates and affects the embossing effect; 2. The spraying component sprays water on the embossing roller to reduce the temperature of the embossing roller and the friction force between the embossing roller and the grinding wheel during the grinding process of the grinding wheel. Furthermore, the grinding effect of grinding the embossing roller is improved. At the same time, the generation of dust during the grinding process can also be reduced. The dust during the grinding process is sucked away by cooperating with the dust suction component, reducing the amount of dust generated during grinding adhering to other positions of the embossing roller. After grinding is completed, the drying component dries the embossing roller, and the embossing roller can continue to perform the embossing work, reducing the impact on the processing efficiency of the embossing roller; 3. A plurality of arc-shaped strips drive the sandpaper to be stably attached to the embossing roller, ensuring the accuracy of grinding the embossing roller. And the rotation of the arc-shaped strips can be driven by controlling the piston rod of the electric push rod to extend, so that the plurality of arc-shaped strips are adjusted to adapt to the outer walls at different diameters of the embossing roller, meeting the precise grinding requirements for different diameters of the embossing roller.

Detailed implementation mode

[0032] The following will further describe this application in detail with reference to the Figures 1-4 accompanying drawings.

[0033] The embodiment of this application discloses a device for detecting concentricity and grinding an embossing roller.

[0034] Referring to Figure 1 , the device for detecting concentricity and grinding an embossing roller includes a bracket 1, a guide rail 2, a rangefinder 3, a control panel 4, a drive mechanism 5, a grinding mechanism 6, a cleaning mechanism 8 and a processing mechanism 9. One bracket 1 is respectively installed on the frames on both sides of the embossing roller through bolts. The two ends of the guide rail 2 are respectively installed on one bracket 1. The rangefinder 3 is slidably installed on the guide rail 2 along the length direction of the guide rail 2. The rangefinder 3 is used to measure the distance from the embossing roller. The rangefinder 3 can be an ultrasonic rangefinder, an infrared rangefinder, etc. In this embodiment, the rangefinder 3 is an ultrasonic rangefinder, which has the characteristics of high precision and strong anti-interference ability; the control panel 4 is installed on the bracket 1, and the control panel 4 is electrically connected to the rangefinder 3. The drive mechanism 5 is installed on the bracket 1. The drive mechanism 5 is used to drive the rangefinder 3 to slide on the guide rail 2. In this embodiment, the drive mechanism 5 includes a drive motor and a drive lead screw. The drive motor is installed on the bracket 1, and the drive motor is electrically connected to the control panel 4. The drive lead screw is rotatably installed on the bracket 1 along the length direction of the guide rail 2. The drive lead screw is coaxially connected to the output shaft of the drive motor. The drive lead screw is threadedly penetrated through the rangefinder 3.

[0035] During the process of embossing the aluminum foil with the embossing roller, the control panel 4 controls the driving motor to start. The output shaft of the driving motor drives the driving lead screw to rotate. The driving lead screw drives the distance measuring instrument 3 to slide from one side of the guide rail 2 to the other side of the guide rail 2. The control panel 4 controls the output shaft of the driving motor to rotate in the reverse direction, which can drive the distance measuring instrument 3 to move in the reverse direction from the other side of the guide rail 2 back to its original position, thus realizing the reciprocating movement of the distance measuring instrument 3 on the guide rail 2. The distance measuring instrument 3 can continuously measure the distance from the embossing roller during the rotation of the embossing roller. If the embossing roller shows wear or deformation, the rotation of the worn or deformed position of the embossing roller will have a jump. Then, the distance data between the different outer peripheral walls of the embossing roller in the same radial direction and the distance measuring instrument 3 measured by the distance measuring instrument 3 will deviate. The distance measuring instrument 3 transmits the measured data to the control panel 4. The control panel 4 can calculate the maximum deviation value of the distance between the different outer peripheral walls of the embossing roller in the same radial direction and the distance measuring instrument 3. If the fluctuation range of the deviation value exceeds the set value, it can be determined that the embossing roller needs to be polished, and thus the concentricity of the embossing roller can be accurately and continuously detected during the process of embossing the aluminum foil with the embossing roller.

[0036] Refer to Figure 1 , Figure 2 , the polishing mechanism 6 is installed on the bracket 1. The polishing mechanism 6 is used to polish the embossing roller. The polishing mechanism 6 includes a driving seat 61, a grinding wheel machine 62 and a control component 63. The driving seat 61 is slidably installed on the guide rail 2 along the length direction of the guide rail 2. The grinding wheel machine 62 is slidably installed on the driving seat 61 along the direction towards the embossing roller. The grinding wheel machine 62 is electrically connected to the control panel 4. In this embodiment, the grinding wheel machine 62 is a hand-held grinding wheel machine, and the rotation direction of the grinding wheel of the grinding wheel machine 62 is along the length direction of the embossing roller. A dovetail groove is formed on the driving seat 61, and the grinding wheel machine 62 slides in the dovetail groove to improve the stability of the grinding wheel machine 62 during the sliding process; the control component 63 is installed on the bracket 1. The control component 63 is used to drive the driving seat 61 and the grinding wheel machine 62 to slide. The control component 63 includes a control motor 631, a control lead screw 632 and a control cylinder 633. The control motor 631 is installed on the bracket 1. The control motor 631 is electrically connected to the control panel 4. The control lead screw 632 is rotatably installed on the bracket 1. The control lead screw 632 is electrically connected to the output shaft of the control motor 631. The control lead screw 632 is threadedly penetrated through the driving seat 61. The control cylinder 633 is installed on the driving seat 61. The control cylinder 633 is electrically connected to the control panel 4. Combined with Figure 3 , a pressure sensor 7 is installed on the piston rod of the control cylinder 633. The pressure sensor 7 is connected to the grinding wheel machine 62. The pressure sensor 7 is electrically connected to the control panel 4.

[0037] After the rangefinder 3 detects that the embossing roller needs to be polished, the control panel 4 drives the control motor 631 to start. The control motor 631 drives the control lead screw 632 to rotate. The control lead screw 632 drives the driving seat 61 to move to the position where the embossing roller needs to be polished, so that the grinding machine 62 is aligned with the position where the embossing roller needs to be polished. Then the control panel 4 drives the piston rod of the control cylinder 633 to extend, so that the grinding wheel of the grinding machine 62 abuts against the embossing roller. The control panel 4 then drives the grinding machine 62 to start, and the grinding machine 62 can stably polish the worn or deformed part of the embossing roller along the length direction of the embossing roller. During the polishing process, the pressure sensor 7 detects the thrust of the piston rod of the control cylinder 633 on the grinding machine 62 and the reaction force of the grinding machine 62 abutting against the embossing roller, and then transmits the detected data to the control panel 4, so that the staff can conveniently control the acting force of the grinding machine 62 abutting against the embossing roller to polish the embossing roller. Furthermore, it is convenient for the staff to precisely control the polishing depth of the embossing roller by the control panel 4. The entire polishing and repair process of the embossing roller does not require the disassembly of the embossing roller, improving the convenience of polishing and repairing the embossing roller and enhancing the processing efficiency of the embossing roller for embossing aluminum foil.

[0038] Refer to Figure 2 、 Figure 3 , the cleaning mechanism 8 is installed on the driving seat 61. The cleaning mechanism 8 is used to clean the embossing roller. The cleaning mechanism 8 includes a spraying component 81, a dust suction component 82 and a drying component 83. The spraying component 81 is installed on the driving seat 61. The spraying component 81 is used to spray water on the embossing roller. The spraying component 81 includes a water tank 811, a water pump 812 and an atomizing nozzle 813. The water tank 811 is installed on the bracket 1. The water pump 812 is installed on the bracket 1. The water pump 812 is electrically connected to the control panel 4. The water inlet end of the water pump 812 is communicated with the water tank 811. The water outlet end of the water pump 812 is communicated with the atomizing nozzle 813 through a corrugated hose. The atomizing nozzle 813 is installed on the driving seat 61. The head of the atomizing nozzle 813 faces the abutting position of the grinding machine 62 and the embossing roller. During the polishing process, the control panel 4 controls the water pump 812 to start. The water pump 812 pumps the water in the water tank 811 to the atomizing nozzle 813, and the water can be atomized and sprayed from the atomizing nozzle 813 to the polishing position of the grinding machine 62 and the embossing roller, cooling the grinding machine 62 and the embossing roller, reducing the possibility of the embossing roller being damaged due to high temperature generated by polishing, and reducing the dust generation amount at the polishing positions of the embossing roller and the grinding machine 62. Furthermore, it reduces the pollution of other parts of the embossing roller during the polishing process.

[0039] Refer to Figure 2 、 Figure 3, the dust collection assembly 82 is installed on the drive seat 61. The dust collection assembly 82 is used to suck away the dust generated at the grinding area of the embossing roller. In this embodiment, the dust collection assembly 82 includes a vacuum cleaner 821 and a dust collection hood 822. The vacuum cleaner 821 is installed on the bracket 1, and the vacuum cleaner 821 is electrically connected to the control panel 4. The dust collection hood 822 is installed on the grinding wheel machine 62, and the dust collection hood 822 is communicated with the vacuum cleaner 821 through a corrugated hose. The dust collection hood 822 covers the grinding wheel of the grinding wheel machine 62 inside. The control panel 4 controls the vacuum cleaner 821 to start. The vacuum cleaner 821 can create a negative pressure at the dust collection hood 822, thereby sucking away the dust generated at the grinding area between the grinding wheel machine 62 and the embossing roller, and further reducing the dust generated during the grinding of the embossing roller.

[0040] Refer to Figure 2 , Figure 3 , the drying assembly 83 is installed on the drive seat 61. The drying assembly 83 is used to dry the embossing roller. In this embodiment, the drying assembly 83 includes a hot air blower 831 and an air outlet 832. The hot air blower 831 is installed on the bracket 1, and the hot air blower 831 is electrically connected to the control panel 4. The air outlet 832 is installed on the drive seat 61, and the air outlet 832 faces the contact area between the grinding wheel machine 62 and the embossing roller. The air outlet 832 is communicated with the hot air blower 831 through a corrugated hose. After the grinding wheel machine 62 finishes grinding the embossing roller, the control panel 4 controls the hot air blower 831 to start. The hot air generated by the hot air blower 831 flows out through the air outlet 832. The hot air can dry the remaining moisture at the grinding area of the embossing roller, and further blow away the remaining dust on the embossing roller, improving the cleanliness of the embossing roller after grinding. Subsequently, the embossing roller can continue the embossing work, reducing the impact on the processing efficiency of the embossing roller due to grinding.

[0041] Refer to Figure 3 , Figure 4 , the processing mechanism 9 is installed on the drive seat 61. The processing mechanism 9 is used to wipe the embossing roller. The processing mechanism 9 includes a carrier 91, a buffer spring 92, a support plate 93, a wiping cloth 94 and a propulsion member 95. The carrier 91 is slidably installed on the drive seat 61 in the direction towards the embossing roller. The propulsion member 95 is installed on the drive seat 61. The propulsion member 95 is used to drive the carrier 91 to slide on the drive seat 61. In this embodiment, the propulsion member 95 is a propulsion cylinder. The propulsion cylinder is electrically connected to the control panel 4. The propulsion cylinder is installed on the drive seat 61 along the sliding direction of the carrier 91. The piston rod of the propulsion cylinder is connected to the carrier 91. The control panel 4 controls the piston rod of the propulsion cylinder to extend, which can drive the carrier 91 to slide on the drive seat 61, making the carrier 91 close to or away from the embossing roller.

[0042] Refer to Figure 3 , Figure 4, A plurality of buffer springs 92 are installed on the carrier 91, and the support plate 93 is installed on the plurality of buffer springs 92. The support plate 93 includes a plurality of arc-shaped strips 931, and the plurality of arc-shaped strips 931 are arranged in sequence and are hinged to each other. One side of each arc-shaped strip 931 facing away from the embossing roller is installed on the buffer spring 92. The buffer spring 92 always has a tendency to drive the arc-shaped strip 931 to rotate in a direction away from the carrier 91, so that the plurality of arc-shaped strips 931 form a circular arc with the center of the circle facing the embossing roller. The positioning assembly 11 is installed on the arc-shaped strip 931. The positioning assembly 11 is used to position the wiping cloth 94 on the arc-shaped strip 931. The positioning assembly 11 includes a positioning bolt 111 and a suction cup 112. The positioning bolt 111 passes through the wiping cloth 94 and extends to the side of the arc-shaped strip 931 away from the embossing roller, and the positioning bolt 111 is threadedly installed on the side of the arc-shaped strip 931 facing away from the embossing roller. The suction cup 112 is installed on the arc-shaped strip 931, and the suction cup 112 is communicated with the vacuum cleaner 821 through a corrugated hose. The suction cup 112 adsorbs on the side of the wiping cloth 94 away from the embossing roller.

[0043] The worker lays the wiping cloth 94 on the plurality of arc-shaped strips 931, so that the wiping cloth 94 covers the side of the arc-shaped support plate 93 formed by the plurality of arc-shaped strips 931 facing the embossing roller. Then, the wiping cloth 94 is tightened, the positioning bolt 111 passes through the wiping cloth 94 and extends to the side of the arc-shaped strip 931 away from the embossing roller, and the positioning bolt 111 is screwed into the arc-shaped strip 931. The vacuum cleaner 821 is used to make the suction cup 112 in a negative pressure state, so that the suction cup 112 adsorbs the wiping cloth 94 on the arc-shaped strip 931, and the wiping cloth 94 can be laid flat and attached to the arc-shaped support plate 93 formed by the plurality of arc-shaped strips 931, improving the adhesion of the wiping cloth 94 on the arc-shaped strip 931. After the embossing roller is polished, the pusher 95 drives the carrier 91 to move in a direction close to the embossing roller. The carrier 91 drives the wiping cloth 94 on the plurality of arc-shaped strips 931 to fit on the outer wall of the embossing roller. The plurality of buffer springs 92 drive the arc-shaped strips 931 to rotate in a direction close to the center of the circle of the plurality of arc-shaped strips 931. The plurality of arc-shaped strips 931 can drive the wiping cloth 94 to fit on the outer wall of the embossing roller. As the embossing roller rotates, the wiping cloth 94 can wipe and clean the embossing roller, and can also drive the driving seat 61 to move along the length direction of the embossing roller, so that the wiping cloth 94 wipes from one side of the embossing roller to the other side. During the process, due to the tendency of the buffer spring 92 to drive the plurality of arc-shaped strips 931 to rotate towards the center of the circle of the plurality of arc-shaped strips 931, the diameter of the arc-shaped support plate 93 formed by the plurality of arc-shaped strips 931 is adapted accordingly. The arc-shaped strip 931 can always fit on the outer wall of different support points of the embossing roller, efficiently clean the embossing roller, ensure the cleanliness of the subsequent embossing roller, and thus improve the embossing effect of the subsequent embossing roller on the aluminum foil.

[0044] Refer to Figure 3 ,Figure 4 A contraction assembly 10 is installed on the carrier 91. The contraction assembly 10 is used to drive multiple arc-shaped bars 931 to rotate towards the center of the multiple arc-shaped bars 931. The contraction assembly 10 includes a support rod 101, a support sleeve 102, an electric push rod 103 and an electromagnet 104. The support sleeve 102 is installed on the carrier 91. One support rod 101 is hinged and installed on the side of the arc-shaped bar 931 away from the embossing roller. The support rod 101 is slidably inserted into the support sleeve 102. The electric push rod 103 is installed on the support sleeve 102. The electric push rod 103 is electrically connected to the control panel 4. The electromagnet 104 is installed on the piston rod of the electric push rod 103. One end of the support rod 101 close to the electromagnet 104 is made of iron. The electromagnet 104 is located on the moving path of the support rod 101 on the support sleeve 102.

[0045] When it is necessary to perform large-area overall grinding on the embossing roller, the staff unscrew the positioning bolt 111, release the adsorption of the suction cup 112 on the wiping cloth 94, remove the wiping cloth 94, then lay the sandpaper on the multiple arc-shaped bars 931, position the sandpaper on the arc-shaped bars 931 through the positioning bolt 111, and adsorb the sandpaper on the arc-shaped bars 931 through the suction cup 112. Then, the carrier 91 drives the multiple arc-shaped plates to move so that the sandpaper fits on the embossing roller. The control panel 4 is used to control the piston rod of the electric push rod 103 to extend, so that the electromagnet 104 abuts against the support rod 101. The control panel 4 is used to control the electromagnet 104 to be energized. The electromagnet 104 can adsorb the support rod 101, so that the piston rod of the electric push rod 103 can drive the support rod 101 to slide on the support sleeve 102. Subsequently, the control panel 4 controls the piston rod of the electric push rod 103 to expand and contract, and the support rod 101 can be used to pull the arc-shaped plate to rotate, so that the radian of the support plate 93 composed of multiple arc-shaped plates matches the outer arc of the embossing roller. Then, the drive seat 61 drives the multiple arc-shaped plates to move along the length direction of the embossing roller. At the same time, in cooperation with the rotation of the embossing roller, large-area grinding of the embossing roller can be performed. During the grinding process, the control panel 4 controls the expansion and contraction of the piston rod of the electric push rod 103, so that the sandpaper can fit the outer wall of the embossing roller at different diameters. Moreover, the electric push rod 103 can also support the arc-shaped plate, so that the sandpaper is stably attached to the embossing roller, meeting the requirement of accurately grinding different diameters of the embossing roller. Moreover, without disassembling the embossing roller, large-area grinding of the embossing roller can be performed, improving the accuracy and grinding effect of large-area overall grinding of the embossing roller.

[0046] The implementation principle of an embossing roll concentricity detection and grinding device according to an embodiment of the present application is as follows: During the process of embossing aluminum foil with the embossing roll, the driving seat 61 reciprocates along the length direction of the embossing roll. The distance measuring instrument 3 continuously detects the distance between the outer peripheral wall of the embossing roll at the same radial position and the distance measuring instrument 3. If the embossing roll is worn or deformed, the distance measuring instrument 3 can detect that the distances between different outer walls of the embossing roll at the same radial position and the distance measuring instrument 3 deviate. When the deviation exceeds the set value, the driving seat 61 drives the grinding wheel 62 to move to the worn or deformed part of the embossing roll, controls the air cylinder 633 to drive the grinding wheel 62 to fit onto the embossing roll, and starts the grinding wheel 62, then the worn or deformed part of the embossing roll can be ground. During the grinding process, the spraying component 81 sprays water mist to cool and dust the grinding area, the dust suction component 82 sucks away the dust generated by grinding, the drying component 83 dries the embossing roll after grinding, and the wiping cloth 94 can also wipe and clean the embossing roll. Subsequently, the embossing roll can directly continue to emboss the aluminum foil. Without disassembling the embossing roll, the embossing roll can be precisely repaired conveniently and quickly, improving the problem that it is difficult to observe the deviation of the concentricity of the embossing roll and affecting the embossing effect.

[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all 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.
