Description

Technical Field

[0001] The present invention relates to the technical field of plastic sheet processing equipment, and specifically relates to a plastic sheet polishing machine for construction. Background Technique

[0002] Plastic sheets for construction refer to lightweight and multifunctional materials made mainly of high molecular compounds and widely used in modern construction. They are corrosion-resistant, waterproof, and easy to process. Plastic sheets can significantly improve the functionality and aesthetics of buildings, and are especially suitable for modern lightweight buildings, energy-saving renovations, and creative design projects.

[0003] Among them, when polishing plastic sheets with a polishing machine, a polishing wheel is often used for polishing. For plastic sheets used in construction, due to storage deformation, there may be local unevenness or inconsistent thickness in the sheets. And the polishing wheel usually rotates at one position. During polishing, the raised or thicker areas of the sheet will bear greater pressure, resulting in faster wear of the corresponding contact area of the polishing wheel, which may cause local wear of the polishing wheel and form depressions, affecting the subsequent polishing effect. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a plastic sheet polishing machine for construction, including a housing, and a conveyor is fixedly connected to the inner wall of the housing;

[0005] A support mechanism, a frame assembly is fixedly installed at the bottom of the support mechanism, and a drive assembly is installed on the inner wall of the support mechanism. The frame assembly is used for conveying plastic sheets;

[0006] A polishing mechanism is installed on the inner wall of the support mechanism for polishing plastic sheets; and

[0007] An extrusion mechanism is located on the inner wall of the support mechanism for flattening plastic sheets;

[0008] Fixed frames are fixedly connected to both the left and right sides of the conveyor. A rotating rod is rotatably connected to the inner walls of the two fixed frames, a gear rod is rotatably connected to the inner walls of the two fixed frames, and a spring push frame is slidably connected to the outer wall of the gear rod;

[0009] Among them, place the plastic sheet on the conveyor, start the conveyor to transport the plastic sheet to the position of the polishing mechanism, polish the plastic sheet, and then extrude the plastic sheet through the extrusion mechanism to make its surface flat, change the polishing position between the polishing machine and the plastic sheet, disperse the contact pressure, and avoid continuous polishing of the same area by the polishing machine, effectively preventing unevenness of the plastic sheet from causing too fast local wear of the polishing machine.

[0010] Preferably, the support mechanism includes:

[0011] The frame component is fixedly arranged at the bottom of the support mechanism and is used to convey the plastic sheet for movement;

[0012] The driving component and the polishing mechanism are fixedly arranged at the inner wall of the support mechanism and are used to drive the polishing mechanism to polish the plastic sheet;

[0013] Among them, the plastic sheet is conveyed to the position of the polishing mechanism by the frame component, and then the polishing mechanism is used to polish the plastic sheet by the driving component.

[0014] Preferably, the polishing mechanism includes:

[0015] The grinding component is slidably arranged on the outer wall of the rotating rod through a sliding part and is used to polish the plastic sheet;

[0016] The sliding part includes a polishing roller arranged on the inner wall of the outer shell, and a gear is fixedly connected to the outer wall of the polishing roller;

[0017] The reciprocating component is fixedly arranged on the outer wall of the rotating rod through a fixing part and is used to blow away the debris generated by the polishing of the plastic sheet;

[0018] The fixing part includes thirty-two fixing rings fixedly connected to the outer wall of the rotating rod, and a connecting rod is fixedly connected to the top of the spring push frame;

[0019] Among them, the plastic sheet conveyed by the frame component will contact the grinding component, and the grinding component is used to polish the plastic sheet. Then, the reciprocating component blows away the debris generated by the polishing of the plastic sheet, changes the polishing position between the polishing roller and the plastic sheet, disperses the contact pressure, and avoids continuous polishing of the same area by the polishing roller. At the same time, the gas ejected inside blows away the debris on the plastic sheet, avoids local protrusion of the plastic sheet, resulting in a closer contact surface between this position and the polishing roller, more debris generated during polishing, causing debris accumulation and secondary wear of the polishing roller. Thus, it effectively prevents unevenness of the plastic sheet from causing excessive local wear of the polishing roller, resulting in local depression of the polishing roller.

[0020] Preferably, the extrusion mechanism includes:

[0021] The roll pressing component is fixedly arranged on the inner wall of the outer shell through a support part and is used to extrude the plastic sheet;

[0022] The support part includes an inclined panel fixedly connected to the inner wall of the outer shell, and a support plate is arranged at the bottom of the inclined panel;

[0023] The centering component is slidably arranged on the outer wall of the support plate through a connecting part and is used to make the plastic sheet transported smoothly;

[0024] The connecting part includes two sliding frames slidably connected to the outer wall of the support plate, and two fixing plates are fixedly connected to the bottom of the inclined panel;

[0025] The air jet assembly is fixedly arranged on the inner wall of the housing through a pusher and is used to clean the debris on the surface of the polishing roller.

[0026] The pusher includes a pneumatic frame fixedly connected to the inner wall of the housing, and a piston plate is slidably connected to the inner wall of the pneumatic frame.

[0027] Among them, the plastic sheet is extruded by the rolling component to make the plastic sheet flat, so that the polishing roller can contact the plastic sheet more evenly, reducing the uneven contact between the polishing roller and the plastic sheet, which helps to ensure a good polishing effect. Then, the two sides of the plastic sheet are limited by the centering component, thereby restricting the lateral movement of the plastic sheet. When the rolling component rolls horizontally to press the plastic sheet flat, it can effectively prevent the excessive extrusion force on the plastic sheet, resulting in the lateral movement of the plastic sheet, making the plastic sheet move synchronously with the polishing roller and affecting the change of the polishing position between the polishing roller and the plastic sheet. Finally, the debris attached to the surface of the polishing roller is removed by the air jet assembly.

[0028] Preferably, the frame assembly includes a motor fixedly connected to the side wall of the housing, and the output end of the motor is fixedly connected to the side wall of the rotating rod.

[0029] The driving assembly includes a slider fixedly connected to the outer wall of the rotating rod.

[0030] Among them, the user places the plastic sheet to be polished on the conveyor, starts the conveyor to transport the plastic sheet towards the polishing roller, and then drives the rotating rod to rotate through the motor, so that the grinding assembly rotates to polish the plastic sheet.

[0031] Preferably, the grinding assembly includes a concave-convex ring fixedly connected to the outer wall of the gear rod, the outer wall of the gear rod is meshed with the outer wall of the gear, and the outer wall of the slider is slidably connected to the inner wall of the polishing roller.

[0032] Among them, when the rotating rod rotates, it drives the slider to rotate, and the polishing roller rotates through the slider. When the plastic sheet moves to the position of the polishing roller, the polishing roller will polish the plastic sheet. When the polishing roller rotates, it will drive the gear to rotate, making the gear rod rotate, and the gear rod will drive the concave-convex ring to rotate.

[0033] Preferably, the reciprocating assembly includes thirty-two air collecting grooves opened on the inner wall of the polishing roller, and the outer walls of the thirty-two fixing rings are all slidably connected to the inner walls of the thirty-two air collecting grooves.

[0034] A plurality of air jet holes are opened on the outer wall of the polishing roller, the side wall of the spring pusher is rotatably connected to the side wall of the polishing roller, and the top of the spring pusher is slidably connected to the inner wall of the housing.

[0035] Among them, during the continuous rotation of the concave-convex ring, when the contact position between the concave-convex ring and the connecting rod moves from the concave position to the convex position, the concave-convex ring will squeeze the connecting rod to move towards the motor direction, driving the spring push frame to move, so that it accumulates resilience. The spring push frame will drive the polishing roller to move, thereby changing the contact position between the polishing roller and the plastic sheet. When the connecting rod contacts the concave position of the concave-convex ring again, the resilience of the spring push frame will be released, causing the spring push frame and the polishing roller to return to their positions. This process repeats, causing the polishing roller to move horizontally back and forth. Among them, when the polishing roller moves towards the motor direction, since the position of the fixed ring remains unchanged, when the spring push frame moves, the fixed ring will squeeze the gas in the air collecting groove, and the squeezed gas will be ejected from the air jet holes, blowing the debris in the polished area of the plastic sheet to move. By changing the polishing position between the polishing roller and the plastic sheet, the contact pressure is dispersed, avoiding continuous polishing of the same area by the polishing roller. At the same time, the gas ejected from the air jet holes blows away the debris on the plastic sheet, preventing local protrusion of the plastic sheet, resulting in a closer contact surface between this position and the polishing roller, more debris generated during polishing, causing debris accumulation and secondary wear of the polishing roller. Thus, it effectively prevents local wear of the polishing roller from being too fast due to unevenness of the plastic sheet, resulting in local depression of the polishing roller.

[0036] Preferably, the roll pressing assembly includes two spring limit rods fixedly connected to the side wall of the spring push frame, and the outer walls of the two spring limit rods are slidably connected to the inner wall of the air jet assembly;

[0037] Four first spring return rods are slidably connected to the inner wall of the support plate. A connecting frame is provided on the top of the conveyor, and the top of the connecting frame is fixedly connected to the bottom of the four first spring return rods. Six pressing rollers are rotatably connected to the inner wall of the connecting frame;

[0038] Among them, when the spring push frame moves towards the motor direction, it will drive the spring limit rods to move. The spring limit rods will drive the support plate, the connecting frame and the pressing rollers to move, causing the support plate to be squeezed by the inclined surface of the inclined panel, making the support plate, the connecting frame and the pressing rollers descend. The support plate will squeeze the spring limit rods, causing them to accumulate resilience. When the pressing rollers move horizontally, they will descend and contact the plastic sheet at the same time. At this time, when the support plate continues to descend, it will squeeze the first spring return rods, causing them to accumulate resilience. The first spring return rods will squeeze the connecting frame, making the pressing rollers apply a greater pressing force to the plastic sheet. Cooperating with the horizontal rolling of the pressing rollers on the plastic sheet, the plastic sheet is flattened, enabling the polishing roller to contact the plastic sheet more evenly, reducing the uneven contact between the polishing roller and the plastic sheet, and helping to ensure a good polishing effect.

[0039] Preferably, the centering assembly includes spring pressing rods slidably connected to the inner wall of the fixed plate. Connecting rods are rotatably connected to the side walls of the two spring pressing rods, and the inner walls of the two connecting rods are rotatably connected to the bottoms of the two sliding frames;

[0040] The outer walls of both sliding frames are slidably connected to the inner walls of the inclined panels. Two roller frames are provided at the top of the conveyor, and the inner walls of the two roller frames are slidably connected to the inner walls of the two spring pressing rods.

[0041] Among them, when the support plate descends, it will also drive the sliding frame to descend. When the sliding frame descends, the connecting rod will rotate, and the connecting rod will push the spring pressing rod to move towards the pressing roller, enabling the spring pressing rod to accumulate resilience. Multiple spring pressing rods will drive the roller frame to contact both sides of the plastic sheet. As the support plate continues to descend, the squeezing force of the pressing roller on the plastic sheet becomes stronger, the squeezing force of the spring pressing rod on the roller frame also becomes stronger, and the squeezing force of the roller frame on both sides of the plastic sheet will also increase, thereby restricting the lateral movement of the plastic sheet. Effectively prevent the squeezing force on the plastic sheet from being too large when the pressing roller rolls horizontally to flatten the sheet, resulting in the lateral movement of the plastic sheet, enabling the plastic sheet to move synchronously with the polishing roller, and affecting the polishing position of the polishing roller relative to the plastic sheet.

[0042] Preferably, the air jet assembly includes a plurality of air inlet holes opened on the inner wall of the air pressure frame. The bottom of the piston plate is fixedly connected to the top of both sliding frames, and a gas blocking plate is slidably connected to the inner wall of the air pressure frame.

[0043] Twenty spring return rods II are fixedly connected to the inner wall of the air pressure frame, and the outer walls of the twenty spring return rods II are slidably connected to the inner wall of the gas blocking plate. A jet plate is fixedly connected to the inner wall of the air pressure frame.

[0044] Among them, when the sliding frame descends, it will also drive the piston plate to descend. When the fixed plate moves past the air inlet hole, the piston plate will squeeze the gas in the air pressure frame. At this time, the squeezed gas will be blocked by the gas blocking plate, so the gas pressure will increase. As the piston plate continues to move, the piston plate will contact the gas blocking plate, thereby pushing the gas blocking plate to descend, squeezing the spring return rods II, and causing the gas blocking plate to cancel the blockage of the gas. At this time, the high-pressure gas will enter the jet plate and be ejected from the jet plate against the outer wall of the polishing roller to remove the debris on the outer wall of the polishing roller, effectively preventing the surface of the polishing roller from having too much debris due to long-term polishing, which affects the polishing of the polishing roller.

[0045] The present invention has the following beneficial effects:

[0046] (1) When the present invention is in use, the user places the plastic sheet to be polished on the conveyor, starts the conveyor to transport the plastic sheet towards the polishing roller, and through the grinding assembly and the reciprocating assembly, changes the polishing position between the polishing roller and the plastic sheet, disperses the contact pressure, and avoids continuous polishing of the same area by the polishing roller. At the same time, the gas ejected from the air jet holes blows away the debris on the plastic sheet, preventing local protrusions on the plastic sheet, resulting in a closer contact surface between this position and the polishing roller, more debris generated during polishing, causing debris accumulation and secondary wear of the polishing roller. Thus, it effectively prevents unevenness of the plastic sheet from causing excessive local wear of the polishing roller and resulting in local depressions on the polishing roller.

[0047] (2) When the spring push frame moves towards the motor in the present invention, it drives the spring limit rod to move, and the spring limit rod drives the support plate to move, causing the support plate to be squeezed by the inclined surface of the inclined panel, making the support plate, the connecting frame, and the pressing roller descend. When the pressing roller moves horizontally, it will descend and contact the plastic sheet at the same time, and cooperate with the pressing roller to roll horizontally on the plastic sheet to flatten the plastic sheet, enabling the polishing roller to contact the plastic sheet more evenly, reducing the uneven contact between the polishing roller and the plastic sheet, and helping to ensure a good polishing effect.

[0048] (3) When the support plate descends in the present invention, it also drives the sliding frame to descend. The descent of the sliding frame causes the connecting rod to rotate, and the connecting rod pushes the spring pressing rod towards the pressing roller direction, enabling the spring pressing rod to accumulate resilience. The spring pressing rod drives the roller frame to contact both sides of the plastic sheet, thereby restricting the horizontal movement of the plastic sheet, effectively preventing the excessive squeezing force on the plastic sheet when the pressing roller rolls horizontally to flatten the sheet, which may cause the plastic sheet to move horizontally, making the plastic sheet move synchronously with the polishing roller and affecting the change of the polishing position between the polishing roller and the plastic sheet.

[0049] (4) When the sliding frame descends in the present invention, it also drives the piston plate to descend, squeezing the gas in the air pressure frame. The gas is blocked by the air blocking plate, and the gas pressure rises until the piston plate pushes the air blocking plate to descend, canceling the block of the gas by the air blocking plate. At this time, the high-pressure gas enters the jet plate and is ejected from the jet plate against the outer wall of the polishing roller to remove the debris at the outer wall of the polishing roller, effectively preventing excessive debris on the surface of the polishing roller due to long-term grinding, which affects the polishing of the polishing roller.

Detailed implementation manners

[0063] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0064] Embodiment 1. Please refer to Figures 1-6 , the present invention is a polishing machine for plastic sheets used in construction, including a housing 111, and a conveyor 112 is fixedly connected to the inner wall of the housing 111;

[0065] A support mechanism 1, a frame assembly 11 is fixedly installed at the bottom of the support mechanism 1, and a driving assembly 12 is installed on the inner wall of the support mechanism 1. The frame assembly 11 is used to convey plastic sheets;

[0066] A polishing mechanism 2, the polishing mechanism 2 is installed on the inner wall of the support mechanism 1 for polishing plastic sheets; and

[0067] An extrusion mechanism 3, the extrusion mechanism 3 is located on the inner wall of the support mechanism 1 for flattening plastic sheets;

[0068] Fixed frames 121 are fixedly connected to both the left and right sides of the conveyor 112. A rotating rod 122 is rotatably connected to the inner walls of the two fixed frames 121. A gear rod 213 is rotatably connected to the inner walls of the two fixed frames 121. A spring push frame 221 is slidably connected to the outer wall of the gear rod 213;

[0069] Among them, place the plastic sheet on the conveyor 112, start the conveyor 112 to convey the plastic sheet to the position of the polishing mechanism 2, polish the plastic sheet, and then extrude the plastic sheet through the extrusion mechanism 3 to make its surface flat, change the polishing position of the polishing machine and the plastic sheet, disperse the contact pressure, avoid continuous polishing of the same area by the polishing machine, and effectively prevent unevenness of the plastic sheet, resulting in excessive local wear of the polishing machine.

[0070] The support mechanism 1 includes:

[0071] A frame assembly 11, the frame assembly 11 is fixedly arranged at the bottom of the support mechanism 1 for conveying the plastic sheet to move;

[0072] A driving assembly 12, the polishing mechanism 2 is fixedly arranged on the inner wall of the support mechanism 1 for driving the polishing mechanism 2 to polish the plastic sheet;

[0073] Among them, the plastic sheet is conveyed to the position of the polishing mechanism 2 through the frame assembly 11, and then the polishing mechanism 2 polishes the plastic sheet through the driving assembly 12.

[0074] The polishing mechanism 2 includes:

[0075] The grinding assembly 21 is slidably arranged on the outer wall of the rotating rod 122 through a sliding member and is used for polishing plastic sheets.

[0076] The sliding member includes a polishing roller 211 arranged on the inner wall of the housing 111, and a gear 212 is fixedly connected to the outer wall of the polishing roller 211.

[0077] The reciprocating assembly 22 is fixedly arranged on the outer wall of the rotating rod 122 through a fixing member and is used for blowing away the debris generated by the polishing of the plastic sheet.

[0078] The fixing member includes thirty-two fixing rings 223 fixedly connected to the outer wall of the rotating rod 122, and a connecting rod 222 is fixedly connected to the top of the spring push frame 221.

[0079] Among them, the plastic sheet conveyed by the frame assembly 11 will contact the grinding assembly 21. The grinding assembly 21 polishes the plastic sheet, and then the reciprocating assembly 22 blows away the debris generated by the polishing of the plastic sheet, changes the polishing position of the polishing roller 211 and the plastic sheet, disperses the contact pressure, and avoids continuous polishing of the same area by the polishing roller 211. At the same time, the gas ejected inside blows away the debris on the plastic sheet, avoiding local protrusion of the plastic sheet, resulting in a closer contact surface between this position and the polishing roller 211, more debris generated during polishing, causing debris accumulation and secondary wear of the polishing roller 211, thereby effectively preventing unevenness of the plastic sheet from causing excessive local wear of the polishing roller 211 and resulting in local depression of the polishing roller 211.

[0080] The extrusion mechanism 3 includes:

[0081] The roll pressing assembly 31 is fixedly arranged on the inner wall of the housing 111 through a support member and is used for extruding plastic sheets.

[0082] The support member includes an inclined panel 311 fixedly connected to the inner wall of the housing 111, and a support plate 313 is arranged at the bottom of the inclined panel 311.

[0083] The centering assembly 32 is slidably arranged on the outer wall of the support plate 313 through a connecting member and is used for enabling the plastic sheet to be transported smoothly.

[0084] The connecting member includes two sliding frames 321 slidably connected to the outer wall of the support plate 313, and two fixing plates 322 are fixedly connected to the bottom of the inclined panel 311.

[0085] The air jet assembly 33 is fixedly arranged on the inner wall of the housing 111 through a pushing member and is used for cleaning the debris on the surface of the polishing roller 211.

[0086] The driving member includes a pneumatic frame 331 fixedly connected to the inner wall of the housing 111, and a piston plate 332 is slidably connected to the inner wall of the pneumatic frame 331;

[0087] Among them, the plastic sheet is extruded by the rolling component 31 to make the plastic sheet flat, so that the polishing roller 211 can contact the plastic sheet more evenly, reducing the uneven contact between the polishing roller 211 and the plastic sheet, which helps to ensure a good polishing effect. Then, the two sides of the plastic sheet are limited by the centering component 32, thereby restricting the lateral movement of the plastic sheet. When the rolling component 31 rolls horizontally to press the plastic sheet flat, the extrusion force on the plastic sheet is too large, resulting in the lateral movement of the plastic sheet, making the plastic sheet move synchronously with the polishing roller 211, affecting the change of the polishing position between the polishing roller 211 and the plastic sheet. Finally, the debris attached to the surface of the polishing roller 211 is removed by the air jet component 33.

[0088] Embodiment 2, please refer to Figures 2-10 , the present invention is a polishing machine for building plastic sheets. On the basis of Example 1, the frame assembly 11 includes a motor 113 fixedly connected to the side wall of the housing 111, and the output end of the side wall of the motor 113 is fixedly connected to the side wall of the rotating rod 122;

[0089] The driving assembly 12 includes a slider 123 fixedly connected to the outer wall of the rotating rod 122;

[0090] Among them, the user places the plastic sheet to be polished on the conveyor 112, starts the conveyor 112 to convey the plastic sheet towards the polishing roller 211, and then drives the rotating rod 122 to rotate through the motor 113, so that the grinding assembly 21 rotates to polish the plastic sheet.

[0091] The grinding assembly 21 includes a concave-convex ring 214 fixedly connected to the outer wall of the gear rod 213, the outer wall of the gear rod 213 is meshed with the outer wall of the gear 212, and the outer wall of the slider 123 is slidably connected to the inner wall of the polishing roller 211;

[0092] Among them, when the rotating rod 122 rotates, it drives the slider 123 to rotate, and the polishing roller 211 is rotated through the slider 123. When the plastic sheet moves to the position of the polishing roller 211, the polishing roller 211 will polish the plastic sheet. When the polishing roller 211 rotates, it will drive the gear 212 to rotate, so that the gear rod 213 rotates, and the gear rod 213 will drive the concave-convex ring 214 to rotate.

[0093] The reciprocating assembly 22 includes thirty-two air collecting grooves 224 opened on the inner wall of the polishing roller 211, and the outer walls of the thirty-two fixing rings 223 are all slidably connected to the inner walls of the thirty-two air collecting grooves 224;

[0094] A number of air jet holes 225 are provided on the outer wall of the polishing roller 211. The side wall of the spring push frame 221 is rotatably connected to the side wall of the polishing roller 211, and the top of the spring push frame 221 is slidably connected to the inner wall of the outer shell 111;

[0095] Among them, during the continuous rotation of the concave-convex ring 214, when the contact position between the concave-convex ring 214 and the connecting rod 222 moves from the concave position to the convex position, the concave-convex ring 214 will squeeze the connecting rod 222 to move in the direction of the motor 113, driving the spring push frame 221 to move, so that it accumulates elastic force. The spring push frame 221 will drive the polishing roller 211 to move, thereby changing the contact position between the polishing roller 211 and the plastic sheet. When the connecting rod 222 contacts the concave position of the concave-convex ring 214 again, the elastic force of the spring push frame 221 will be released, causing the spring push frame 221 and the polishing roller 211 to return to their original positions. This process repeats, causing the polishing roller 211 to move horizontally back and forth. Among them, when the polishing roller 211 moves in the direction of the motor 113, since the position of the fixed ring 223 remains unchanged, when the spring push frame 221 moves, the fixed ring 223 will squeeze the gas in the air collecting groove 224, and the squeezed gas will be ejected from the air jet holes 225, blowing the debris in the polished area of the plastic sheet to move. By changing the polishing position between the polishing roller 211 and the plastic sheet, the contact pressure is dispersed, preventing the polishing roller 211 from continuously polishing the same area. At the same time, the gas ejected from the air jet holes 225 blows away the debris on the plastic sheet, preventing the plastic sheet from bulging locally, resulting in a closer contact surface between this position and the polishing roller 211, generating more debris during polishing, causing debris accumulation and secondary wear of the polishing roller 211, thereby effectively preventing the local wear of the polishing roller 211 from being too fast due to the unevenness of the plastic sheet, resulting in local depression of the polishing roller 211.

[0096] The roller pressing assembly 31 includes two spring limiting rods 312 fixedly connected to the side wall of the spring push frame 221, and the outer walls of the two spring limiting rods 312 are slidably connected to the inner wall of the air jetting assembly 33;

[0097] Four first spring return rods 314 are slidably connected to the inner wall of the support plate 313. A connecting frame 315 is provided on the top of the conveyor 112, and the top of the connecting frame 315 is fixedly connected to the bottom of the four first spring return rods 314. Six pressing rollers 316 are rotatably connected to the inner wall of the connecting frame 315;

[0098] Among them, when the spring push frame 221 moves towards the motor 113, it will drive the spring limit rod 312 to move. The spring limit rod 312 will drive the support plate 313, the connecting frame 315 and the extrusion roller 316 to move, so that the support plate 313 is extruded by the inclined surface of the inclined panel 311, causing the support plate 313, the connecting frame 315 and the extrusion roller 316 to descend. The support plate 313 will extrude the spring limit rod 312 to store its resilience. When the extrusion roller 316 moves horizontally, it will descend and contact the plastic sheet at the same time. At this time, when the support plate 313 continues to descend, it will extrude the first spring return rod 314 to store its resilience. The first spring return rod 314 will extrude the connecting frame 315, so that the extrusion roller 316 exerts a greater extrusion force on the plastic sheet. Cooperating with the horizontal rolling of the extrusion roller 316 on the plastic sheet, the plastic sheet is flattened, enabling the polishing roller 211 to contact the plastic sheet more evenly, reducing the uneven contact between the polishing roller 211 and the plastic sheet, and helping to ensure a good polishing effect.

[0099] The centering assembly 32 includes spring extrusion rods 323 slidably connected to the inner wall of the fixed plate 322. Connecting rods 324 are rotatably connected to the side walls of the two spring extrusion rods 323, and the inner walls of the two connecting rods 324 are rotatably connected to the bottoms of the two sliding frames 321;

[0100] The outer walls of the two sliding frames 321 are slidably connected to the inner wall of the inclined panel 311. Two roller frames 325 are provided on the top of the conveyor 112, and the inner walls of the two roller frames 325 are slidably connected to the inner walls of the two spring extrusion rods 323;

[0101] Among them, when the support plate 313 descends, it will also drive the sliding frame 321 to descend. The descent of the sliding frame 321 will cause the connecting rod 324 to rotate. The connecting rod 324 will push the spring extrusion rod 323 to move towards the extrusion roller 316, causing the spring extrusion rod 323 to store its resilience. Multiple spring extrusion rods 323 will drive the roller frames 325 to contact both sides of the plastic sheet. As the support plate 313 continues to descend, the extrusion force of the extrusion roller 316 on the plastic sheet is stronger, the extrusion force of the spring extrusion rod 323 on the roller frame 325 is also stronger, and the extrusion force of the roller frame 325 on both sides of the plastic sheet will also increase, thereby restricting the lateral movement of the plastic sheet. Effectively preventing the plastic sheet from moving laterally due to excessive extrusion force when the extrusion roller 316 rolls horizontally to flatten the sheet, enabling the plastic sheet to move synchronously with the polishing roller 211 and affecting the polishing position of the polishing roller 211 relative to the plastic sheet.

[0102] The air jet assembly 33 includes a plurality of air inlet holes 333 opened on the inner wall of the air pressure frame 331. The bottoms of the piston plates 332 are fixedly connected to the tops of the two sliding frames 321, and an air blocking plate 334 is slidably connected to the inner wall of the air pressure frame 331;

[0103] Twenty spring return rods II 335 are fixedly connected to the inner wall of the air pressure frame 331. The outer walls of the twenty spring return rods II 335 are all slidably connected to the inner wall of the air blocking plate 334. A jet plate 336 is fixedly connected to the inner wall of the air pressure frame 331;

[0104] Among them, when the sliding frame 321 descends, it will also drive the piston plate 332 to descend. When the fixed plate 322 moves past the air inlet hole 333, the piston plate 332 will squeeze the gas in the air pressure frame 331. At this time, the squeezed gas will be blocked by the air blocking plate 334. Therefore, the gas pressure will increase. As the piston plate 332 continues to move, the piston plate 332 will contact the air blocking plate 334, thereby pushing the air blocking plate 334 to descend, squeezing the spring return rods II 335, and causing the air blocking plate 334 to cancel the block of the gas. At this time, the high-pressure gas will enter the jet plate 336 and be ejected from the jet plate 336 against the outer wall of the polishing roller 211 to remove the debris on the outer wall of the polishing roller 211, effectively preventing excessive debris on the surface of the polishing roller 211 due to long-term polishing, which affects the polishing of the polishing roller 211.

[0105] The quantity of the above components is not limited, and those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0106] A specific application of this embodiment is as follows: When the present invention is in use, the user places the plastic sheet to be polished on the conveyor 112, starts the conveyor 112 to convey the plastic sheet towards the polishing roller 211, then starts the motor 113 to rotate the rotating rod 122, causing the slider 123 to rotate, and drives the polishing roller 211 to rotate through the slider 123. When the plastic sheet moves to the position of the polishing roller 211, the polishing roller 211 will polish the plastic sheet. When the polishing roller 211 rotates, it will drive the gear 212 to rotate, causing the gear rod 213 to rotate. The gear rod 213 will drive the concave-convex ring 214 to rotate. During the continuous rotation of the concave-convex ring 214, when the contact position between the concave-convex ring 214 and the connecting rod 222 moves from the concave position to the convex position, the concave-convex ring 214 will squeeze the connecting rod 222 to move towards the motor 113 direction, driving the spring push frame 221 to move, so that it accumulates elastic return force. The spring push frame 221 will drive the polishing roller 211 to move, thereby changing the contact position between the polishing roller 211 and the plastic sheet. When the connecting rod 222 contacts the concave position of the concave-convex ring 214 again, the elastic return force of the spring push frame 221 will be released, causing the spring push frame 221 and the polishing roller 211 to return to their original positions. This process repeats, causing the polishing roller 211 to reciprocate horizontally. Among them, when the polishing roller 211 moves towards the motor 113 direction, due to the fixed position of the fixed ring 223, when the spring push frame 221 moves, the fixed ring 223 will squeeze the gas in the air collecting groove 224, causing the compressed gas to be ejected from the air jet hole 225, blowing the debris in the polished area of the plastic sheet to move. By changing the polishing position between the polishing roller 211 and the plastic sheet, the contact pressure is dispersed, preventing the polishing roller 211 from continuously polishing the same area. At the same time, the gas ejected from the air jet hole 225 blows away the debris on the plastic sheet, preventing local protrusions on the plastic sheet, resulting in a closer contact surface between this position and the polishing roller 211, more debris generated during polishing, causing debris accumulation, and causing secondary wear of the polishing roller 211. Thus, it effectively prevents the unevenness of the plastic sheet from causing excessive local wear of the polishing roller 211, resulting in local depression of the polishing roller 211;

[0107] Secondly, when the spring push frame 221 moves towards the motor 113, it will drive the spring limit rod 312 to move. The spring limit rod 312 will drive the support plate 313, the connecting frame 315 and the extrusion roller 316 to move, so that the support plate 313 is extruded by the inclined surface of the inclined panel 311, causing the support plate 313, the connecting frame 315 and the extrusion roller 316 to descend. The support plate 313 will extrude the spring limit rod 312 to store its resilience. When the extrusion roller 316 moves horizontally, it will descend and contact the plastic sheet at the same time. At this time, when the support plate 313 continues to descend, it will extrude the first spring return rod 314 to store its resilience. The first spring return rod 314 will extrude the connecting frame 315, so that the extrusion roller 316 exerts a greater extrusion force on the plastic sheet. Cooperating with the horizontal rolling of the extrusion roller 316 on the plastic sheet, the plastic sheet is flattened, enabling the polishing roller 211 to contact the plastic sheet more evenly, reducing the uneven contact between the polishing roller 211 and the plastic sheet, and helping to ensure a good polishing effect;

[0108] Secondly, when the support plate 313 descends, it will also drive the sliding frame 321 to descend. The descent of the sliding frame 321 will cause the connecting rod 324 to rotate. The connecting rod 324 will push the spring extrusion rod 323 to move towards the extrusion roller 316, causing the spring extrusion rod 323 to store its resilience. Multiple spring extrusion rods 323 will drive the roller frame 325 to contact both sides of the plastic sheet. As the support plate 313 continues to descend, the extrusion force of the extrusion roller 316 on the plastic sheet becomes stronger, the extrusion force of the spring extrusion rod 323 on the roller frame 325 also becomes stronger, and the extrusion force of the roller frame 325 on both sides of the plastic sheet will also increase, thereby restricting the lateral movement of the plastic sheet. Effectively preventing the extrusion force on the plastic sheet from being too large when the extrusion roller 316 rolls horizontally to flatten the sheet, resulting in the lateral movement of the plastic sheet, enabling the plastic sheet to move synchronously with the polishing roller 211 and affecting the polishing position of the polishing roller 211 on the plastic sheet;

[0109] Secondly, when the sliding frame 321 descends, it will also drive the piston plate 332 to descend. When the fixed plate 322 moves past the air inlet hole 333, the piston plate 332 will squeeze the gas in the air pressure frame 331. At this time, the squeezed gas will be blocked by the air blocking plate 334, so the gas pressure will increase. As the piston plate 332 continues to move, the piston plate 332 will contact the air blocking plate 334, thereby pushing the air blocking plate 334 to descend and squeezing the second spring return rod 335, causing the air blocking plate 334 to cancel the block of the gas. At this time, the high-pressure gas will enter the jet plate 336 and be ejected from the jet plate 336 against the outer wall of the polishing roller 211, clearing the debris on the outer wall of the polishing roller 211, effectively preventing the surface of the polishing roller 211 from having too much debris after long-term polishing, which affects the polishing of the polishing roller 211;

[0110] Among them, when the resilience of the spring pushing frame 221 is released and it returns to its original position, the spring limiting rod 312 and the support plate 313 will return to their original positions. At this time, the resilience of the spring limiting rod 312 will be released, causing the support plate 313 to rise, the sliding frame 321 to rise, and the piston plate 332 to rise and return to its original position. The air inlet hole 333 will then communicate with the bottom of the piston plate 332, allowing external gas to enter.
