[0005] The present invention provides a fully automatic metal polishing device, which aims to solve the technical problem that in the process of grinding a metal strip, the metal powder generated by grinding is very fine and easily magnetized. After working for a long time, it will adhere to the surface of the polishing roller and the steel strip, affecting the polishing effect. Moreover, after working for a long time, a large amount of heat will be generated on the surface of the polishing roller. If the heat is not dissipated in time, it will not only affect the service life of the polishing roller, but also affect the polishing quality of the surface of the metal strip.

[0006] A fully automatic metal polishing device of the present invention comprises: a polishing chamber and a polishing mechanism arranged in the polishing chamber, the polishing mechanism comprises two polishing modules symmetrically arranged up and down, the polishing module comprises a polishing unit, a gap for a metal strip to pass through is formed between the polishing units of the two polishing modules, and the polishing module further comprises a cleaning unit and a cooling unit; the polishing unit comprises a frame arranged in the polishing chamber, a mounting frame mounted on the frame for forward and backward movement, a polishing roller rotating on the mounting frame, a driving assembly for driving the polishing roller to rotate around its axis, and a driving member for driving the mounting frame to move forward and backward on the frame; the cleaning unit comprises two cleaning magnets arranged on both sides of the polishing roller and in horizontal sliding cooperation with the frame , the cleaning magnets are rotatably connected with a connecting rod, and the other end of the connecting rod is rotatably matched with the mounting frame, so that the mounting frame drives the two cleaning magnets to move toward each other in the left and right directions. A sealed cavity is provided on the frame, and an air hole facing the polishing roller is provided at the bottom of the sealed cavity. A sliding plate is fixedly installed on the cleaning magnet, and a through hole is provided on the side wall of the sealed cavity in the left and right directions. One end of the sliding plate passes through the through hole and extends into the sealed cavity. A plug plate is fixedly installed on one end of the sliding plate located in the sealed cavity, and the plug plate is sealingly slidably matched with the cavity wall of the sealed cavity, and the sliding matching direction of the plug plate is the same as the sliding matching direction of the cleaning magnet; the cooling unit includes a heat exchanger, which is arranged in the sealed cavity and is used to cool the gas in the sealed cavity.

[0007] Beneficial effect: When the reciprocating cylinder drives the mounting frame and the polishing roller to continuously reciprocate in the front-to-back direction, the mounting frame will drive the cleaning magnets on both sides to continuously slide back and forth in the left-to-right direction through the connecting rod. The two cleaning magnets move towards each other, which can effectively increase the adsorption area and adsorption effect of the metal powder on the surface of the metal strip, thereby ensuring that the metal powder on the surface of the metal strip is cleaned. The two cleaning magnets will drive the plug plates to slide in the sealed chamber and drive the two plug plates to move towards each other. When the two plug plates move away from each other, the gas on the outside will be sucked into the sealed chamber through the air holes. The pump body transports the coolant in the cooling chamber to the cooling pipe through the liquid inlet pipe. All the cooling pipes can take away the heat in the sealed chamber, thereby cooling the air in the sealed chamber and cooling the gas entering the sealed chamber. As the two plug plates approach each other at the same time, the cooling air in the sealed chamber is squeezed out from the air holes again, and the cooling gas ejected from the air holes can be sprayed onto the polishing roller. On the one hand, it can cool the polishing roller to prevent the polishing roller from being overheated and affecting the polishing effect and reducing the life of the polishing roller. On the other hand, the gas ejected from the air holes can blow off the metal powder attached to the polishing roller and improve the polishing effect of the polishing roller. The metal powder blown off the polishing roller will be absorbed by the cleaning magnets on both sides.

[0008] Preferably, the frame is provided with a storage cavity, which is located on the left side of the polishing roller. The storage cavity can be used to store polishing agent. The frame is provided with a blanking channel connected to the storage cavity. The frame is also provided with a closing plate for opening and closing the blanking channel. The closing plate has an open position and a closed position. When the cleaning magnet moves in the left and right directions, it can drive the closing plate to switch between the closed position and the open position. The cleaning magnet is provided with a through hole that passes through the upper and lower parts. A loading sponge is provided in the through hole. When the closing plate is in the open position, the loading sponge is located at the discharge end of the blanking channel. The polishing agent can enter the loading sponge through the blanking channel, and the loading sponge contacts the surface of the metal strip on the side away from the blanking channel.

[0009] The effect is that before the metal strip enters the polishing roller, the polishing agent is first applied to the metal strip to ensure the polishing effect.

[0010] Preferably, there are two air holes arranged obliquely and in an eight-shaped arrangement, and the gas blown out from the air holes can be tangent to the outer peripheral surface of the polishing roller, and a filter is arranged on the air holes.

[0011] The effect is that the metal powder on the polishing roller can be blown off better.

[0012] Preferably, the cooling chamber is connected with a liquid inlet pipe and a liquid outlet pipe, and both the liquid inlet pipe and the liquid outlet pipe are connected with the cooling pipe, and the cooling chamber is also provided with a heat dissipation mechanism for cooling the coolant.

[0013] The effect is that the coolant is circulated between the cooling chamber and the cooling pipe, and the heat dissipation mechanism can continuously cool the coolant.

[0014] Preferably, adsorption magnets are fixedly mounted on the frame on both the left and right sides of the polishing roller, and the adsorption magnets are wrapped with flannel.

[0015] The effect is that the magnets on both sides will absorb the metal strip in the process of conveying, and the flannel will be isolated between the metal strip and the magnets, and the flannel can effectively avoid damage to the metal strip. It can not only ensure the normal conveying of the metal strip, but also fix the two ends of the metal strip during the polishing process to prevent the metal strip from shaking during polishing. The flannel can also wipe the surface of the metal strip to improve the polishing effect of the metal strip.

[0016] Preferably, the driving assembly includes a driving motor fixedly mounted on a frame, a driving wheel is fixedly mounted on the output end of the driving motor, a driven wheel is also rotatably mounted on the frame, the driven wheel is connected to the driving wheel by a transmission belt, a connecting shaft is coaxially fixedly mounted on the driven wheel, the connecting shaft is coaxially arranged with the polishing roller, the connecting shaft and the polishing roller are circumferentially fixedly engaged and axially slidingly engaged.

[0017] Preferably, a lifting cylinder is installed in the polishing chamber, and the telescopic part of the lifting cylinder is fixedly connected to the frame.

[0018] Preferably, the driving member is a reciprocating cylinder fixedly mounted on the frame, and the telescopic portion of the reciprocating cylinder is fixedly connected to the mounting frame so that the mounting frame can slide back and forth on the frame in a front-rear direction.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0020] When the reciprocating cylinder drives the mounting frame and the polishing roller to continuously reciprocate along the front-to-back direction, the mounting frame will drive the cleaning magnets on both sides to continuously move toward each other through the connecting rod, which can effectively increase the adsorption area and adsorption effect of the metal powder on the surface of the metal strip, thereby ensuring that the metal powder on the surface of the metal strip is cleaned. The two cleaning magnets will drive the plug plates to slide in the sealed chamber. When the two plug plates move away from each other, the gas on the outside will be sucked into the sealed chamber through the pores. The pump body will transport the coolant in the cooling chamber to the cooling pipe through the liquid inlet pipe. All the cooling pipes can take away the heat in the sealed chamber, thereby cooling the air in the sealed chamber and cooling the gas entering the sealed chamber. As the two plug plates approach each other at the same time, the cooling air in the sealed chamber will be squeezed out from the pores again, and the cooling gas ejected from the pores can be sprayed onto the polishing roller. On the one hand, it can cool the polishing roller to prevent the polishing roller from being overheated and affecting the polishing effect and reducing the life of the polishing roller. On the other hand, the gas ejected from the pores can blow off the metal powder attached to the polishing roller, thereby improving the polishing effect of the polishing roller. The metal powder blown off the polishing roller will be absorbed by the cleaning magnets on both sides.

[0021] The magnets on both sides will absorb the metal strip during transportation, and the flannel will be isolated between the metal strip and the magnets. The flannel can effectively prevent damage to the metal strip. It can not only ensure the normal transportation of the metal strip, but also fix the two ends of the metal strip during the polishing process to prevent the metal strip from shaking during polishing. The flannel can also wipe the surface of the metal strip to improve the polishing effect of the metal strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, a specific embodiment of a fully automatic metal polishing device of the present invention includes a unwinding roller 10, a winding roller 11, a polishing chamber 20 and a plurality of polishing mechanisms installed inside the polishing chamber 20; each polishing mechanism includes two polishing modules symmetrically arranged up and down, and the metal strip passes through between the two polishing modules for polishing treatment, and each polishing module includes a polishing unit, a cleaning unit, a cooling unit, a polishing agent application unit and a fixing unit.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the unwinding roller 10 and the winding roller 11 are respectively arranged on both sides of the polishing chamber 20, and the conveying direction of the metal strip is set to the left-right direction, and the width direction of the metal strip is set to the front-back direction. In this embodiment, the unwinding roller 10 is located on the left side of the polishing chamber 20, and the winding roller 11 is located on the right side of the polishing chamber 20. The unwinding roller 10 is used to install the metal strip and unwind the metal strip at the same time, and the winding roller 11 is used to wind up the polished metal strip.

[0034] A feed port 21 is provided on the left side of the polishing chamber 20, and a discharge port 22 is provided on the right side of the polishing chamber 20. Both the feed port 21 and the discharge port 22 are rectangular structures that match the metal strip. Guide rollers are rotatably installed on the feed port 21 and the discharge port 22 for conducting the metal strip. The metal strip released from the unwinding roller 10 enters the polishing chamber 20 through the feed port 21. A gap is provided between the two groups of polishing modules symmetrically arranged up and down for the metal strip to pass through. The metal strip passes through between the two groups of polishing modules for polishing treatment, passes out from the discharge port 22 after polishing, and is finally wound up on the winding roller 11.

[0035] An inspection window is provided on the front side wall of the polishing chamber 20 , so that workers can quickly repair the internal structure of the polishing chamber 20 when a device fails.

[0036] Each group of polishing mechanisms includes two groups of polishing modules that are symmetrically arranged in the polishing chamber 20. In this embodiment, the two groups of polishing modules have exactly the same structure. The metal strip passes through the two groups of polishing modules. The upper polishing module can polish the upper surface of the metal strip, and the lower polishing module can polish the lower surface of the metal strip, thereby completing the comprehensive polishing process of the metal strip.

[0037] like Figures 3 to 7 As shown, the polishing unit includes a frame 30, a lifting cylinder 31, a mounting frame 32, a reciprocating cylinder 33, a polishing roller 34 and a driving assembly.

[0038] The frame 30 can be lifted and installed in the polishing chamber 20 by means of a lifting cylinder 31. The lifting cylinder 31 is fixedly installed in the polishing chamber 20. The telescopic part of the lifting cylinder 31 is fixedly connected to the frame 30, so that the lifting cylinder 31 can drive the frame 30 to lift and lower, and adjust the distance between the frame 30 and the metal strip. By adjusting the upper and lower frames 30 in each set of polishing mechanisms, the gap between the two frames 30 can be adjusted to adapt to metal strips of different thicknesses, thereby improving the applicability of the device.

[0039] A mounting frame 32 is slidably installed on the inner side of the frame 30 along the front-to-back direction. The mounting frame 32 is a U-shaped structure. The frame 30 is provided with a slide groove arranged along the front-to-back direction. A slider is fixedly provided on the mounting frame 32. The slider on the mounting frame 32 slides in the slide groove on the frame 30.

[0040] A reciprocating cylinder 33 is fixedly mounted on the frame 30 , and a telescopic portion of the reciprocating cylinder 33 is fixedly connected to the mounting frame 32 , so that the mounting frame 32 is driven by the reciprocating cylinder 33 to continuously slide back and forth on the frame 30 in the front-rear direction.

[0041] A polishing roller 34 is mounted on the mounting frame 32 so as to rotate horizontally along the front-rear direction. That is, the axial direction of the polishing roller 34 is consistent with the width direction of the metal strip, so that when the polishing roller 34 rotates, the passing metal strip can be polished. It is particularly noted that the polishing roller 34 can rotate around its own axis and can also continuously slide back and forth along its axis direction, so as to improve the polishing effect on the metal strip.

[0042] The driving assembly is used to drive the polishing roller 34 to rotate, and includes a driving motor 35 , a driving wheel 36 , a driven wheel 37 and a connecting shaft 38 .

[0043] The driving motor 35 is fixedly mounted on the frame 30, and a driving wheel 36 is fixedly mounted on the output end of the driving motor 35, so that the driving motor 35 drives the driving wheel 36 to rotate. A driven wheel 37 is also rotatably mounted on the frame 30, and the driven wheel 37 is connected to the driving wheel 36 through a transmission belt, so that the driving wheel 36 can drive the driven wheel 37 to rotate at the same time.

[0044] A connecting shaft 38 is fixedly mounted on the driven wheel 37. The connecting shaft 38 is coaxially arranged with the driven wheel 37. At the same time, the connecting shaft 38 is coaxially arranged with the polishing roller 34, and the connecting shaft 38 and the polishing roller 34 are slidably matched. The connecting shaft 38 and the polishing roller 34 are slidably connected by means of a slide groove and a slider (not shown in the figure). The slide groove and the slider make the connecting shaft 38 and the polishing roller 34 stop rotating in the circumferential direction, and make the connecting shaft 38 and the polishing roller 34 slide in the axial direction. That is, the polishing roller 34 can slide along the axial direction of the connecting shaft 38, and the connecting shaft 38 can also drive the polishing roller 34 to rotate.

[0045] When the polishing roller 34 is polishing the metal strip, a large amount of metal powder will be generated. The generated metal powder is very fine and easily magnetized. After working for a long time, it will adhere to the surface of the polishing roller 34 and the metal strip, affecting the polishing effect. Therefore, the metal powder on the metal strip needs to be continuously cleaned so that there is no metal powder attached to the surface of the metal strip transported from the polishing chamber 20 to ensure the polishing quality of the metal strip.

[0046] For ease of understanding, the following description of the polishing modules takes a group of polishing modules located at the top as an example.

[0047] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the cleaning unit includes a connecting rod 40, a cleaning magnet 41, a sealing chamber 42, a sliding plate 43, a plug plate 44 and an air hole 45.

[0048] The left and right sides of the polishing roller 34 are both provided with cleaning magnets 41, and the cleaning magnets 41 are horizontally slidably matched with the mounting frame 32. The cleaning magnets 41 on both sides are rectangular structures, and the length direction of the cleaning magnets 41 is horizontal with the axial direction of the polishing roller 34.

[0049] It is particularly noted that there is a certain gap between the cleaning magnets 41 on the left and right sides and the polishing roller 34, so as to ensure the normal polishing work of the polishing roller 34, and the plane where the lowest point of the polishing roller 34 is located is lower than the lower surface of the cleaning magnet 41, which not only prevents the cleaning magnet 41 from interfering with the polishing process of the polishing roller 34 on the metal strip, but also ensures that there is a certain distance between the cleaning magnet 41 and the metal strip, and there is enough storage space at the bottom of the cleaning magnet 41 to absorb the metal powder on the metal strip.

[0050] The metal strip passes under the two cleaning magnets 41. A large amount of metal powder will be generated during the polishing of the metal strip by the inner polishing roller 34. The metal powder floating in the air will be adsorbed by the cleaning magnets 41 on both sides. When the metal powder adsorbed on the surface of the metal strip passes under the cleaning magnet 41, the bottom of the cleaning magnet 41 will adsorb the metal powder on the surface of the metal strip.

[0051] Continue back Figure 4 , Figure 5 and Figure 7 , the two cleaning magnets 41 are horizontally slidably matched with the frame 30 along the left-right direction, and each cleaning magnet 41 is connected to the mounting frame 32 through two connecting rods 40, one end of the connecting rod 40 is rotatably connected to the cleaning magnet 41, and the other end of the connecting rod 40 is rotatably connected to the mounting frame 32. The rotation axis of the rotational connection between the cleaning magnet 41 and the connecting rod 40 is parallel to the rotation axis of the rotational connection between the connecting rod 40 and the mounting frame 32. The two connecting rods 40 installed on each cleaning magnet 41 are arranged in parallel, that is, the two connecting rods 40 on each cleaning magnet 41 have the same inclination angle.

[0052] When the reciprocating cylinder 33 drives the mounting frame 32 and the polishing roller 34 to continuously reciprocate in the front-to-back direction, the mounting frame 32 drives the cleaning magnets 41 on both sides to continuously slide back and forth in the left-to-right direction through the connecting rod 40. It is particularly emphasized that when the two cleaning magnets 41 continuously slide back and forth, they move toward each other, that is, the two cleaning magnets 41 will simultaneously approach the polishing roller 34 or simultaneously move away from the polishing roller 34.

[0053] When the two cleaning magnets 41 continuously move back and forth in the left and right directions, the adsorption area and adsorption effect of the metal powder on the surface of the metal strip can be effectively increased, thereby ensuring that the metal powder on the surface of the metal strip is cleaned.

[0054] A sealed cavity 42 is provided on the frame 30, and the sealed cavity 42 is located directly above the polishing roller 34. The sealed cavity 42 is a rectangular structure, and the length direction of the sealed cavity 42 is horizontal to the axis direction of the polishing roller 34. An air hole 45 is provided at the bottom of the sealed cavity 42 corresponding to the polishing roller 34, and the air hole 45 is located in the middle of the sealed cavity 42. There are two air holes 45, and they are arranged in an eight-shaped shape, and a filter screen is arranged on each of the air holes 45.

[0055] A sliding plate 43 is fixedly installed on the cleaning magnet 41, and the sliding plate 43 is arranged horizontally. Perforations are opened on the side walls of the sealed cavity 42 in the left and right directions. One end of the sliding plate 43 extends into the sealed cavity 42 through the perforations, and the sliding plate 43 slides with the perforations on the side walls of the sealed cavity 42 in the left and right directions. The sliding direction of the sliding plate 43 is the same as the sliding direction of the cleaning magnet 41. A plug plate 44 is fixedly installed on one end of the sliding plate 43 located in the sealed cavity 42, and the upper and lower surfaces and the front and rear surfaces of the plug plate 44 are sealed and slidably matched with the corresponding side walls of the sealed cavity 42.

[0056] As the two cleaning magnets 41 on both sides continuously slide back and forth in the left and right directions, the plug plate 44 will be driven to slide in the sealed chamber 42. The two plug plates 44 in the sealed chamber 42 also move in opposite directions. When the two plug plates 44 move away from each other at the same time, the gas on the outside will be sucked into the sealed chamber 42 through the air holes 45. The cooling unit can cool the gas entering the sealed chamber 42, and then as the two plug plates 44 approach each other at the same time, the cooling air in the sealed chamber 42 will be squeezed out from the air holes 45 again. The cooling gas ejected from the air holes 45 can be sprayed toward the polishing roller 34. On the one hand, it can cool the polishing roller 34 to prevent the polishing roller 34 from being overheated and affecting the polishing effect and reducing the life of the polishing roller 34. On the other hand, the gas ejected from the air holes 45 can blow off the metal powder attached to the polishing roller 34, thereby improving the polishing effect of the polishing roller 34. The metal powder blown off from the polishing roller 34 will be adsorbed by the cleaning magnets 41 on both sides.

[0057] It is particularly noted that the air holes 45 are arranged in an eight-shaped shape, and the gas blown out from the air holes 45 is tangent to the surface of the polishing roller 34, which can better blow off the metal powder attached to the polishing roller 34. The filter on the air holes 45 can prevent the metal powder from entering the sealing cavity 42 from the air holes 45 along with the air, and can play an effective filtering role.

[0058] Continue back Figure 4 , Figure 5 and Figure 6 The cooling unit includes a cooling pipe 50 , a liquid inlet pipe 51 , a liquid outlet pipe 52 and a cooling chamber 53 .

[0059] A plurality of cooling tubes 50 are fixedly installed in the middle of the sealed cavity 42, and the axes of the cooling tubes 50 are arranged along the front-to-back direction. In this embodiment, the cooling tubes 50 are vertically arranged in four rows, and each row is arranged with at least three cooling tubes 50. It is particularly noted that in this embodiment, all the cooling tubes 50 are interconnected.

[0060] A cooling chamber 53 is fixedly mounted on the frame 30, and a coolant is arranged in the cooling chamber 53. A liquid inlet pipe 51 and a liquid outlet pipe 52 are connected between the cooling chamber 53 and the cooling tube 50, and a pump body (not shown in the figure) is installed on the cooling chamber 53. The pump body transports the coolant in the cooling chamber 53 to the cooling tube 50 through the liquid inlet pipe 51. All cooling tubes 50 can take away the heat in the sealed cavity 42, thereby cooling the air in the sealed cavity 42. The coolant that takes away the heat finally flows back to the inside of the cooling chamber 53 through the liquid outlet pipe 52 to achieve circulation. At the same time, a heat dissipation mechanism (not shown in the figure) is also arranged in the cooling chamber 53, and the heat dissipation mechanism can continuously dissipate heat and cool down the coolant in the cooling chamber 53 to ensure the cooling effect of the cooling tube 50.

[0061] The polishing agent applying unit is used to apply polishing agent to the surface of the metal strip before the metal strip is polished to ensure the polishing effect of the metal strip.

[0062] like Figure 4 As shown, the polishing agent applying unit includes a storage chamber 60 , a material dropping channel 61 , a closing plate 62 and a loading sponge 63 .

[0063] The storage chamber 60 is arranged on the frame 30, and polishing agent is stored in the storage chamber 60. The storage chamber 60 has a discharge port at the bottom, and a feeding pump (not shown in the figure) is installed at the discharge port at the bottom of the storage chamber 60. A vertical blanking channel 61 is arranged on the frame 30, and the blanking channel 61 is connected to the discharge port at the bottom of the storage chamber 60, so that the polishing agent in the storage chamber 60 can be pumped into the blanking channel 61 through the feeding pump.

[0064] A closing plate 62 is horizontally slidably connected to the frame 30 via a spring. When not in operation, the closing plate 62 is located at the bottom opening of the material dropping channel 61 , and can block the material dropping channel 61 .

[0065] The cleaning magnet 41 on the left side has a through hole extending from top to bottom, and a loading sponge 63 is fixedly installed in the through hole. It should be noted that the plane where the bottom of the loading sponge 63 is located is lower than the plane where the bottom of the cleaning magnet 41 is located, so that the loading sponge 63 can abut against the surface of the metal strip.

[0066] The cleaning magnet 41 on the left side continuously pushes the closing plate 62 during the reciprocating motion. When the closing plate 62 is pushed to the left, the bottom of the blanking channel 61 is opened. At the same time, the loading sponge 63 corresponds to the bottom of the blanking channel 61. The polishing agent in the storage chamber 60 passes through the blanking channel 61 and enters the loading sponge 63, and then is smeared on the metal strip through the loading sponge 63. It should be noted that in this embodiment, the polishing agent is in liquid form.

[0067] When the cleaning magnet 41 moves to the right, the elastic force of the spring on the closing plate 62 is released, and the closing plate 62 is pushed back to return to its original position to close the blanking channel 61, and the cycle continues.

[0068] Since the metal strip is relatively thin and cannot be effectively fixed during the conveying process, the metal strip may shake when the polishing roller 34 continuously polishes the metal strip, thereby affecting the polishing quality. In this embodiment, a fixing unit is used to solve this problem.

[0069] like Figure 4 As shown, the fixing unit includes an adsorption magnet 70 and a flannel 71 .

[0070] Adsorption magnets 70 are fixedly installed near the left and right sides of the bottom of the frame 30, and the bottom of the adsorption magnets 70 is wrapped with flannel 71. When the metal strip passes through the bottom of the frame 30, the adsorption magnets 70 on the left and right sides will adsorb the metal strip in transit, and the flannel 71 will be isolated between the metal strip and the adsorption magnets 70. The flannel 71 can effectively avoid damage to the metal strip. It can not only ensure the normal transportation of the metal strip, but also fix the two ends of the metal strip during the polishing process to avoid the metal strip from shaking during polishing. The flannel 71 can also wipe the surface of the metal strip to improve the polishing effect of the metal strip.

[0071] It is particularly noted that if both the upper and lower groups of frames 30 are provided with adsorption magnets 70, the metal strip passing between the two groups of frames 30 may affect the adsorption of the metal strip by the adsorption magnets 70. Therefore, in this embodiment, the adsorption magnets 70 and the flannel cloth 71 are only installed on one of the two groups of frames 30.

[0072] The working principle of the present invention is as follows: the metal strip released from the unwinding roller 10 enters the polishing chamber 20 through the feed port 21 for polishing. The metal strip passes between the upper and lower polishing rollers 34. The driving motor 35 drives the driving wheel 36 to rotate, and the driving wheel 36 can drive the driven wheel 37 to rotate at the same time. The driven wheel 37 drives the polishing roller 34 to rotate, and the reciprocating cylinder 33 can drive the polishing roller 34 to slide back and forth along its axial direction. While the polishing roller 34 rotates, it can also continuously reciprocate along the axial direction to polish the metal strip passing through the upper and lower polishing rollers 34.

[0073] When the reciprocating cylinder 33 drives the mounting frame 32 and the polishing roller 34 to continuously reciprocate along the front-back direction, the mounting frame 32 drives the cleaning magnets 41 on both sides to continuously slide back and forth along the left-right direction through the connecting rod 40. The two cleaning magnets 41 move towards each other, and when the two cleaning magnets 41 continuously reciprocate along the left-right direction, the adsorption area and adsorption effect of the metal powder on the surface of the metal strip can be effectively increased, thereby ensuring that the metal powder on the surface of the metal strip is cleaned.

[0074] As the two cleaning magnets 41 on both sides continuously slide back and forth in the left and right directions, the plug plate 44 will be driven to slide in the sealed cavity 42. The two plug plates 44 in the sealed cavity 42 also move in opposite directions. When the two plug plates 44 move away from each other at the same time, the gas on the outside will be sucked into the sealed cavity 42 through the air holes 45, and the pump body will transport the coolant in the cooling chamber 53 to the cooling tube 50 through the liquid inlet pipe 51. All the cooling tubes 50 can take away the heat in the sealed cavity 42, thereby cooling the air in the sealed cavity 42. The coolant that takes away the heat finally flows back to the inside of the cooling chamber 53 through the liquid outlet pipe 52 to achieve circulation. In this way, the gas entering the sealed cavity 42 can be cooled, and then as the two plug plates 44 approach each other at the same time, the cooling air in the sealed cavity 42 is squeezed out from the air holes 45 again. The cooling gas ejected from the air hole 45 can be sprayed toward the polishing roller 34. On the one hand, it can cool down the polishing roller 34 to prevent the polishing roller 34 from being overheated and affecting the polishing effect and reducing the life of the polishing roller 34. On the other hand, the gas ejected from the air hole 45 can blow off the metal powder attached to the polishing roller 34 to improve the polishing effect of the polishing roller 34. The metal powder blown off the polishing roller 34 will be absorbed by the cleaning magnets 41 on both sides.

[0075] As the cleaning magnet 41 on the left side continuously reciprocates left and right, it will continuously push the closing plate 62. When the closing plate 62 is pushed toward the left, the bottom of the blanking channel 61 will be opened. At the same time, the loading sponge 63 corresponds to the bottom of the blanking channel 61. The polishing agent in the storage chamber 60 will pass through the blanking channel 61 and enter the loading sponge 63. Then, it will be smeared on the metal strip through the loading sponge 63. The metal strip coated with the polishing agent will be polished by the polishing roller 34.

[0076] Finally, the polished metal strip passes through the discharge port 22 and is wound on the winding roller 11 .

[0077] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
