Description

Technical Field

[0001] This invention relates to the field of non-stick pan manufacturing technology, specifically a polishing device for non-stick pan production. Background Technology

[0002] In the non-stick cookware manufacturing industry, aluminum and aluminum alloy sheets are one of the most widely used core substrates. Stainless steel, cast iron, and titanium alloys are also commonly used as substrates for cookware bodies. Among these, food-grade aluminum sheets hold a significant position in the consumer non-stick cookware market due to their high thermal conductivity, lightweight nature, and controllable production costs. Their preparation involves multiple processes, including aluminum smelting, deep-well casting, hot rolling, cold rolling, slicing, and annealing. During these processes, the surface of the aluminum sheets is prone to defects such as oxide scale, rolling oil stains, fine scratches, and burrs. These defects directly affect the adhesion and uniformity of the subsequent non-stick coating, thus reducing the lifespan and safety performance of the finished cookware. Therefore, the polishing quality of the aluminum sheets directly determines the surface smoothness and coating adhesion stability of the finished non-stick cookware, thereby affecting its performance and lifespan. Existing polishing equipment for producing non-stick cookware aluminum sheets still has many shortcomings in practical applications. For example, an aluminum sheet polishing device with publication number CN222405012U uses a support rod, motor, half gear, toothed block, and push rod. The half gear drives the toothed block and push rod to move, the push rod drives the push plate to move, and the push plate moves the aluminum sheet through a sliding groove. The aluminum sheet is then pushed onto the conveyor belt, completing the aluminum sheet feeding process. This eliminates the uncertainty that may be caused by manual placement and reduces the risk of potential inconsistencies and quality fluctuations caused by manual operation. However, in use, this technical solution has insufficient positioning accuracy for aluminum sheet conveying. The device lacks a dedicated flattening and guiding structure, and warping and edge protrusions caused by aluminum sheet storage or transportation cannot be corrected. Posture deviation is prone to occur during conveying, and the conveyor belt lacks an anti-slip limit design, making it easy for the aluminum sheet to slide relative to the conveyor belt. This leads to positional deviations when entering the polishing area, resulting in uneven polishing and incomplete polishing in some areas, affecting processing accuracy and yield. Meanwhile, the existing polishing equipment has poor debris collection effect. During polishing operations, a large amount of aluminum chips are generated and splashed. The splashed aluminum chips not only pollute the production environment and increase the workshop cleaning burden, but also easily adhere to other transmission parts of the equipment, causing parts to jam and wear, increasing the probability of equipment failure. In addition, the aluminum chips are scattered in various parts of the equipment and cannot be collected in a concentrated manner. Some chips will accumulate around the polishing area, or even adhere to the surface of the aluminum sheet to be processed or already processed, further affecting the polishing quality. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a polishing device for non-stick pan production, comprising: The workbench and the conveying mechanism mounted on top of it are equipped with a protective housing fixedly mounted on top of the workbench. The protective housing is positioned directly above the conveying mechanism and is used to isolate aluminum chips splashed during the polishing process, preventing the chips from spreading and polluting the environment and affecting the safety of the operators. A chip collection mechanism and a fan are respectively installed on both sides of the protective housing. The protective housing, together with the chip collection mechanism and the fan, forms a directional chip guiding space to improve chip collection efficiency. When the fan is running, it generates a directional airflow that blows the aluminum chips generated by the polishing mechanism and pushes the chips along the inner wall of the protective housing, eventually causing them to fall into the chip collection mechanism. This prevents the chips from adhering to the surface of the aluminum sheet and affecting the polishing quality. An operation panel is installed on the outer surface of the protective housing, and rotating doors are rotatably installed at both ends of the protective housing. A flattening and guiding mechanism is installed at both ends of the protective housing. The flattening and guiding mechanism is squeezed and adapted to the conveying mechanism. The flattening and guiding mechanism assists in conveying the aluminum sheet on the surface of the conveying mechanism so that it can smoothly enter the polishing area. At the same time, it guides the aluminum sheet on both sides to prevent it from deviating during the polishing process. The polishing mechanism is installed in the middle of the inner cavity of the worktable and is located directly above the conveying mechanism. The flattening and guiding mechanisms are symmetrically arranged on both sides of the polishing mechanism. The polishing mechanism is used to polish aluminum sheets. The flattening guide mechanism includes an I-beam and a slide. The I-beam is fixedly installed on the inner wall of the protective housing, and the top of the slide is slidably mounted on the outer surface of the I-beam. The I-beam guides the sliding of the slide, ensuring the vertical lifting of the slide and the components below. The slide slides along the I-beam, facilitating the flattening and guiding of aluminum sheets of different thicknesses. A return spring is fixedly connected between the slide and the I-beam. The return spring buffers the impact force caused by the sliding of the slide and the conveying of the aluminum sheets, preventing damage to components. In case of rigid collision damage, guide members are rotatably installed at both ends of the bottom of the slide, and pressure rollers are rotatably installed on both sides of the bottom of the slide. The pressure rollers are positioned between the guide members. The return spring provides elastic reset and buffering for the slide, ensuring that the slide, along with the pressure rollers and guide members below, always has downward pressure to meet the flattening requirements of the aluminum sheet. The guide members, in conjunction with the pressure rollers, guide the aluminum sheet on both sides, preventing the aluminum sheet from shifting left or right during conveying and polishing, ensuring accurate polishing position of the aluminum sheet, and simultaneously assisting in flattening the aluminum sheet and improving polishing uniformity.

[0004] Preferably, the conveying mechanism includes a conveying frame and a motor. The conveying frame is fixedly installed on the top of the workbench, and the motor is fixedly installed on the outer surface of the conveying frame via a bracket. Conveying rollers are rotatably installed at both ends of the conveying frame, and one of the conveying rollers is fixedly connected to the output end of the motor. A conveyor belt is driven to be installed on the outer surface of the conveying roller. The motor drives the conveying roller to rotate, thereby driving the conveyor belt to achieve continuous conveying of the aluminum sheet. The conveyor belt is used to receive the non-stick aluminum sheet and smoothly deliver the aluminum sheet into the polishing area.

[0005] Preferably, a support roller is rotatably installed inside the conveyor frame. The outer surface of the support roller is pressed and adapted to the inner surface of the conveyor belt. The support roller is used to support the conveyor belt and prevent it from sinking and deforming due to the pressure of the aluminum sheet and the flattening guide mechanism, thus ensuring that the conveyor belt always maintains a horizontal conveying state. Anti-slip strips are fixedly installed on the outer surface of the conveyor belt. The anti-slip strips are evenly distributed on the surface of the conveyor belt and are used to increase the friction between the conveyor belt and the aluminum sheet, preventing relative sliding of the aluminum sheet during conveying, flattening, and polishing, thus ensuring accurate conveying displacement of the aluminum sheet and no deviation in the polishing position.

[0006] Preferably, the guide includes a rotating rod rotatably mounted on the bottom of the slide. A pressure cylinder is fixedly mounted on the outer surface of the rotating rod. The rotating rod drives the pressure cylinder to rotate synchronously with the aluminum sheet being conveyed. Fan-shaped grooves are opened at both ends of the pressure cylinder, and the fan-shaped grooves are evenly distributed along the axis of the pressure cylinder. A guide rail is fixedly mounted inside the fan-shaped groove. An inclined block is slidably mounted on the outer surface of the guide rail. The guide rail provides a precise sliding track for the inclined block, ensuring that the inclined block slides along the guide rail to adapt to the side guiding requirements of aluminum sheets of different thicknesses and widths. A frame is fixedly mounted on the outer surface of the inclined block. A pressing wheel is rotatably mounted inside the frame via a rotating shaft. The pressing wheel fits against the two sides of the aluminum sheet and rotates synchronously with the aluminum sheet being conveyed, playing a limiting and guiding role for the aluminum sheet to prevent it from deviating. It can also help flatten the edges of the aluminum sheet to avoid the edges from lifting and affecting the polishing effect.

[0007] Preferably, a buffer spring is fixedly connected between the inclined block and the inner wall of the fan-shaped groove. The buffer spring provides elastic buffering and resetting for the inclined block, causing the pressure wheel to elastically fit against the side of the aluminum sheet, adapting to aluminum sheets of different widths. At the same time, it buffers the impact force during the conveying process, preventing damage to the edge of the aluminum sheet. The edge of the pressure wheel is pressed against the conveyor belt to help flatten the aluminum sheet during conveying, preventing uneven polishing caused by warping or protrusion of the aluminum sheet, ensuring that the aluminum sheet fits smoothly against the conveyor belt and improving the polishing quality.

[0008] Preferably, a second chip guide groove is provided on the inner wall of the protective housing. The second chip guide groove is located directly above the chip collection mechanism. The second chip guide groove is used to receive the debris blown by the fan. The depth of the second chip guide groove gradually increases from top to bottom, which facilitates guiding the debris to slide quickly to the chip collection mechanism side and avoids the debris from accumulating on the inner wall of the protective housing.

[0009] Preferably, the chip collection mechanism includes a chip collection box, which is slidably installed on the surface of the protective housing. The chip collection box is used to receive and centrally store polishing aluminum chips guided and conveyed by the fan. The sliding design allows operators to pull it out periodically and quickly clean the chips accumulated in the box, making maintenance convenient. A handle is installed on the outer surface fixed plate of the chip collection box. A chip guide plate is rotatably installed on one side of the top of the chip collection box via a rotating shaft. The chip guide plate is used to receive chips from the chip guide groove and the surface of the conveyor belt, and at the same time, it plays a transitional guiding role for the chips, guiding the chips to fall smoothly into the chip collection box and preventing the chips from scattering outside the chip collection box. A support spring is fixedly connected between the chip guide plate and the outer surface of the chip collection box. The support spring provides elastic support for the chip guide plate to maintain the tilting guide angle of the chip guide plate and ensure smooth chip guidance. At the same time, the chip guide plate can rotate adaptively when the chip collection box is disassembled, which is convenient for disassembly and installation. When the equipment is working, the support spring vibrates, allowing the chips on the chip guide plate to smoothly enter the chip collection box.

[0010] Preferably, the upper surface of the chip guide plate is provided with a chip guide groove, which is evenly distributed on the surface of the chip guide plate. The feed end of the chip guide plate is slightly lower than the upper surface of the conveyor belt. The chip guide groove diverts and guides the chips, avoiding a large amount of chips from accumulating locally on the chip guide plate and causing blockage, thus ensuring that the chips flow quickly and smoothly into the chip collection box.

[0011] Preferably, the polishing mechanism includes a lifting platform and a second motor. The lifting platform is fixedly installed at the bottom of the inner cavity of the workbench, and a mounting frame is fixedly installed on the top of the lifting platform. The second motor is fixedly installed at the bottom of the inner side of the mounting frame, and a first transmission wheel is fixedly connected to the output end of the second motor. A transmission shaft is rotatably installed on the top of the mounting frame, and a second transmission wheel is fixedly installed at one end of the outer surface of the transmission shaft. A transmission belt is installed between the outer surfaces of the first and second transmission wheels. The lifting platform provides support for the mounting frame and is used to drive the top mounting frame and polishing components to move vertically up and down, so as to adjust the distance between the polishing roller, the chip removal roller and the aluminum sheet, and adapt to the polishing requirements of non-stick aluminum sheets of different thicknesses.

[0012] Preferably, there are two motors and two drive shafts, with the drive shafts positioned directly above the motors. Polishing rollers and chip-sweeping rollers are fixedly mounted on the outer surfaces of the two drive shafts, respectively. The polishing rollers are positioned near the feed end of the mounting frame. The motor drives the first drive wheel to rotate, and the first drive wheel transmits power to the second drive wheel via a drive belt, achieving directional power transmission and ensuring stable rotation of the drive shaft. The drive shaft drives the polishing rollers and chip-sweeping rollers on the outer surfaces to rotate synchronously, providing torque support for polishing and chip-sweeping operations. The polishing rollers are used to grind and polish the aluminum sheet for non-stick pans, ensuring that the surface of the aluminum sheet meets the smoothness requirements for non-stick pan production. The chip-sweeping rollers are used to clean the surface of the polished aluminum sheet, removing residual polishing debris adhering to the surface of the aluminum sheet and ensuring a clean surface after polishing.

[0013] This invention provides a polishing apparatus for non-stick pan production. It has the following beneficial effects: (I) The polishing device for non-stick pan production, through the setting of the flattening and guiding mechanism, uses pressure rollers to flatten the warped parts of the aluminum sheet surface, and pressure rollers to precisely limit and guide the two sides of the aluminum sheet. At the same time, it can adapt to aluminum sheets of different widths and thicknesses, buffer the impact force during the conveying process, and avoid the aluminum sheet from shifting or warping during the conveying and polishing process. It ensures that the aluminum sheet conveying trajectory is accurate and the surface is flat. The flattening and guiding mechanism makes the aluminum sheet evenly stressed during polishing, improves the consistency of the polished surface smoothness, and avoids local incomplete polishing or over-polishing due to shifting or warping. It ensures the pass rate of non-stick pan aluminum sheet polishing, and is also compatible with the processing of aluminum sheets of multiple specifications, improving the versatility of the device.

[0014] (II) The polishing device for non-stick pan production, through the setting of the polishing mechanism, adjusts the distance between the polishing roller, the chip sweeping roller and the aluminum sheet by the lifting platform to adapt to the processing requirements of different thicknesses. The polishing roller grinds and polishes the aluminum sheet, and the chip sweeping roller simultaneously sweeps away residual debris on the polished surface. This completes the polishing operation of the aluminum sheet and cleans the residual debris on the surface at the same time, ensuring that aluminum sheets of different thicknesses can meet the smoothness standard required for non-stick pan production. At the same time, the real-time cleaning of residual debris prevents secondary adhesion of debris from affecting the polishing quality, improves the cleanliness of the polished aluminum sheet, and improves the overall polishing efficiency.

[0015] (III) The polishing device for non-stick pan production, through the setting of the chip collection mechanism, forms a closed working space with the protective shell. The operation of the fan generates a directional airflow, which blows the polishing debris along the inner wall of the protective shell to the chip guide groove two. The chip guide groove two has a shallow upper and deep lower structure to guide the debris to slide down quickly. In the chip collection mechanism, the chip guide plate is kept in an inclined position under the support of the support spring, which receives the sliding debris and guides it through the surface chip guide groove one. The support spring drives the chip guide plate to shake slightly with the vibration of the equipment to assist the falling of the debris. Finally, the debris is concentrated and falls into the chip collection box. The chip collection mechanism efficiently collects polishing debris, isolates debris splash pollution, ensures a clean working environment, and avoids debris adhering to the polishing roller and aluminum sheet surface, affecting the polishing quality. The pull-out design of the chip collection box reduces the difficulty of cleaning debris and improves the safety and convenience of operation.

[0016] (iv) The polishing device for non-stick pan production, through the setting of the conveying mechanism, the motor drives the conveying roller to rotate, which drives the conveyor belt to realize the continuous conveying of aluminum raw sheets. The support roller inside the conveyor frame provides bottom support for the conveyor belt, and the anti-slip strip on the outer surface of the conveyor belt increases the contact friction with the aluminum raw sheets, realizing stable, continuous and precise directional conveying of aluminum raw sheets, providing continuous material transfer support for subsequent processes, ensuring accurate conveying displacement of aluminum raw sheets, and improving the overall polishing efficiency of non-stick pan aluminum raw sheets.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] For the first embodiment, please refer to... Figure 1-6 The present invention provides a technical solution: a polishing device for non-stick pan production, comprising: The workbench 1 and the conveying mechanism 2 installed on its top are provided. A protective shell 3 is fixedly installed on the top of the workbench 1. The protective shell 3 is located directly above the conveying mechanism 2. The protective shell 3 is used to isolate aluminum chips that splash during the polishing process, so as to prevent the chips from spreading and polluting the environment and affecting the safety of the operators. A chip collection mechanism 4 and a fan 9 are installed on both sides of the protective shell 3, respectively. The protective shell 3, together with the chip collection mechanism 4 and the fan 9, forms a directional chip guiding space to improve chip collection efficiency. When the fan 9 is running, it generates a directional airflow, which blows the aluminum chips generated by the polishing mechanism 6 and pushes the chips along the inner wall of the protective shell 3, and finally falls into the chip collection mechanism 4, so as to prevent the chips from adhering to the surface of the aluminum sheet and affecting the polishing quality. An operation panel 8 is installed on the outer surface of the protective shell 3. Rotating doors 7 are rotatably installed at both ends of the protective shell 3. A chip guide groove 2 10 is provided on the inner wall of the protective housing 3. The chip guide groove 2 10 is located directly above the chip collection mechanism 4. The chip guide groove 2 10 is used to receive the debris blown by the fan 9. The depth of the chip guide groove 2 10 gradually increases from top to bottom, which facilitates guiding the debris to slide quickly to the side of the chip collection mechanism 4 and avoids the debris from accumulating on the inner wall of the protective housing 3. The conveying mechanism 2 includes a conveying frame 21 and a motor 22. The conveying frame 21 is fixedly installed on the top of the workbench 1. The motor 22 is fixedly installed on the outer surface of the conveying frame 21 through a bracket. Conveying rollers 23 are rotatably installed at both ends of the conveying frame 21. One of the conveying rollers 23 is fixedly connected to the output end of the motor 22. A conveyor belt 24 is driven to the outer surface of the conveying roller 23. The motor 22 drives the conveying roller 23 to rotate, thereby driving the conveyor belt 24 to achieve continuous conveying of aluminum sheets. The conveyor belt 24 is used to receive non-stick aluminum sheets and smoothly send the aluminum sheets into the polishing area. A support roller 26 is rotatably installed inside the conveyor frame 21. The outer surface of the support roller 26 is pressed and matched with the inner side of the conveyor belt 24. The support roller 26 is used to support the conveyor belt 24 and prevent the conveyor belt 24 from sinking and deforming due to the pressure of the aluminum sheet and the flattening guide mechanism 5. This ensures that the conveyor belt 24 always maintains a horizontal conveying state. Anti-slip strips 25 are fixedly installed on the outer surface of the conveyor belt 24. The anti-slip strips 25 are evenly distributed on the surface of the conveyor belt 24. The anti-slip strips 25 are used to increase the friction between the conveyor belt 24 and the aluminum sheet, and prevent the aluminum sheet from sliding relative to each other during the conveying, flattening and polishing process. This ensures that the aluminum sheet is accurately conveyed and the polishing position is without deviation. The chip collection mechanism 4 includes a chip collection box 41, which is slidably mounted on the surface of the protective housing 3. The chip collection box 41 is used to receive and centrally store the polishing aluminum chips guided and conveyed by the fan 9. The sliding design makes it easy for operators to pull it out periodically and quickly clean the chips accumulated in the box, making maintenance convenient. A handle 45 is installed on the outer surface fixed plate of the chip collection box 41. A chip guide plate 42 is rotatably mounted on one side of the top of the chip collection box 41 via a rotating shaft. The chip guide plate 42 is used to receive chips from the chip guide groove 10 and the surface of the conveyor belt 24, and at the same time, it serves as a transition guide for the chips. The guide plate 42 guides the debris to fall smoothly into the chip collection box 41, preventing the debris from scattering outside the chip collection box 41. A support spring 44 is fixedly connected between the chip guide plate 42 and the outer surface of the chip collection box 41. The support spring 44 provides elastic support to the chip guide plate 42 to maintain the tilting guide angle of the chip guide plate 42 and ensure smooth chip guidance. At the same time, the chip guide plate 42 can rotate adaptively when the chip collection box 41 is disassembled, which is convenient for disassembly and installation. When the equipment is working, the support spring 44 vibrates, so that the debris on the chip guide plate 42 can smoothly enter the chip collection box 41. The upper surface of the chip guide plate 42 is provided with a chip guide groove 43. The chip guide groove 43 is evenly distributed on the surface of the chip guide plate 42. The feed end of the chip guide plate 42 is slightly lower than the upper surface of the conveyor belt 24. The chip guide groove 43 diverts and guides the chips to avoid a large amount of chips accumulating locally on the chip guide plate 42 and causing blockage, thus ensuring that the chips flow quickly and smoothly into the chip collection box 41. Flattening guide mechanism 5 is installed at both ends of the protective housing 3. Flattening guide mechanism 5 is squeezed and adapted to conveying mechanism 2. Flattening guide mechanism 5 assists in conveying the aluminum sheet on the surface of conveying mechanism 2 so that it can smoothly enter the polishing area. At the same time, it guides the aluminum sheet on both sides to prevent it from deviating during the polishing process. Polishing mechanism 6 is installed in the middle of the inner cavity of workbench 1 and is located directly above conveying mechanism 2. Flattening guide mechanism 5 is symmetrically arranged on both sides of polishing mechanism 6. Polishing mechanism 6 is used to polish aluminum sheet.

[0021] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 7-9 As shown, the flattening guide mechanism 5 includes an I-beam 51 and a slide 52. The I-beam 51 is fixedly installed on the inner wall of the protective housing 3. The top of the slide 52 is slidably installed on the outer surface of the I-beam 51. The I-beam 51 provides guidance for the sliding of the slide 52, ensuring the vertical lifting of the slide 52 and the components below it. The slide 52 slides along the I-beam 51, which is convenient for adapting to the flattening and guiding requirements of aluminum sheets of different thicknesses. A return spring 53 is fixedly connected between the slide 52 and the I-beam 51. The return spring 53 buffers the impact force caused by the sliding of the slide 52 and the conveying of the aluminum sheets, avoiding... In the event of a rigid collision damage to a component, guide members 54 are rotatably mounted at both ends of the bottom of the slide 52, and pressure rollers 55 are rotatably mounted on both sides of the bottom of the slide 52. The pressure rollers 55 are positioned between the guide members 54. The return spring 53 provides elastic reset and buffering for the slide 52, ensuring that the slide 52, along with the pressure rollers 55 and guide members 54, always maintains downward pressure to meet the flattening requirements of the aluminum sheet. The guide members 54, in conjunction with the pressure rollers 55, guide the aluminum sheet on both sides, preventing the aluminum sheet from shifting left or right during conveying and polishing, ensuring accurate polishing position of the aluminum sheet, and simultaneously assisting in flattening the aluminum sheet and improving polishing uniformity. The guide component 54 includes a rotating rod 541, which is rotatably mounted on the bottom of the slide 52. A pressure cylinder 542 is fixedly mounted on the outer surface of the rotating rod 541. The rotating rod 541 drives the pressure cylinder 542 to rotate synchronously with the aluminum sheet conveying. The two ends of the pressure cylinder 542 are provided with fan-shaped grooves 543, which are evenly distributed along the axis of the pressure cylinder 542. A guide rail 544 is fixedly mounted inside the fan-shaped grooves 543, and a wedge block 545 is slidably mounted on the outer surface of the guide rail 544. The guide rail 544 is a wedge block. 545 provides a precise sliding track to ensure that the inclined block 545 slides along the guide rail 544 to adapt to the side guiding requirements of aluminum sheets of different thicknesses and widths. A frame 546 is fixedly installed on the outer surface of the inclined block 545. Inside the frame 546, a pressure wheel 547 is rotatably installed via a rotating shaft. The pressure wheel 547 fits against the two sides of the aluminum sheet and rotates synchronously with the aluminum sheet being conveyed, which plays a limiting and guiding role for the aluminum sheet to prevent it from deviating. It can also help to flatten the edges of the aluminum sheet and avoid the edges from lifting up and affecting the polishing effect. A buffer spring 548 is fixedly connected between the inclined block 545 and the inner wall of the fan-shaped groove 543. The buffer spring 548 plays an elastic buffering and resetting role on the inclined block 545, driving the pressure wheel 547 to elastically fit the side of the aluminum sheet, adapting to aluminum sheets of different widths, and buffering the impact force during the conveying process to avoid damaging the edge of the aluminum sheet. The edge of the pressure wheel 547 is squeezed and matched with the conveyor belt 24 to assist in flattening the aluminum sheet during the conveying process, avoiding uneven polishing caused by warping or protrusion of the aluminum sheet, ensuring that the aluminum sheet fits smoothly with the conveyor belt 24 for conveying, and improving the polishing quality.

[0022] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 10-11 As shown, the polishing mechanism 6 includes a lifting platform 61 and a second motor 63. The lifting platform 61 is fixedly installed at the bottom of the inner cavity of the workbench 1. A mounting frame 62 is fixedly installed on the top of the lifting platform 61. The second motor 63 is fixedly installed on the bottom of the inner side of the mounting frame 62. A transmission wheel 64 is fixedly connected to the output end of the second motor 63. A transmission shaft 65 is rotatably installed on the top of the mounting frame 62. A second transmission wheel 66 is fixedly installed at one end of the outer surface of the transmission shaft 65. A transmission belt 67 is installed between the outer surfaces of the first transmission wheel 64 and the second transmission wheel 66. The lifting platform 61 provides support for the mounting frame 62 and is used to drive the top mounting frame 62 and the polishing components to move vertically up and down, so as to adjust the distance between the polishing roller 68, the chip sweeping roller 69 and the aluminum sheet, and adapt to the polishing requirements of non-stick aluminum sheets of different thicknesses. There are two motors 63 and two drive shafts 65, with the drive shafts 65 positioned directly above the motors 63. Polishing rollers 68 and chip-sweeping rollers 69 are fixedly mounted on the outer surfaces of the two drive shafts 65, respectively. The polishing rollers 68 are positioned near the feed end of the mounting frame 62. The motors 63 drive the drive wheel 64 to rotate, and the drive wheel 64 transmits power to the drive wheel 66 via the drive belt 67, achieving directional power transmission and ensuring stable rotation of the drive shafts 65. The drive shafts 65 drive the polishing rollers 68 and chip-sweeping rollers 69 on their outer surfaces to rotate synchronously, providing torque support for polishing and chip-sweeping operations. The polishing rollers 68 are used to grind and polish the aluminum sheet for non-stick pans, ensuring that the surface of the aluminum sheet meets the smoothness requirements for non-stick pan production. The chip-sweeping rollers 69 are used to clean the surface of the polished aluminum sheet, removing residual polishing debris and ensuring a clean surface after polishing.

[0023] During use, the operator places the aluminum sheet to be polished stably on the feed end of the conveyor belt 24 of the conveying mechanism 2. The anti-slip strip 25 increases the friction between the aluminum sheet and the conveyor belt 24 to prevent slippage after placement. The device is started, and the motor 22 is energized to output torque, driving the conveyor roller 23 fixed to it to rotate. This drives the conveyor belt 24 to move stably along the two sets of conveyor rollers 23, and simultaneously moves the aluminum sheet to the polishing area inside the protective housing 3. During this process, the support roller 26 inside the conveyor frame 21 provides stable support to the inside of the conveyor belt 24, preventing the conveyor belt 24 from sinking or deforming due to the weight of the aluminum sheet and the pressure of the subsequent flattening guide mechanism 5. This maintains the horizontal conveying state of the conveyor belt 24 and ensures that the aluminum sheet moves forward smoothly. When the aluminum sheet moves with the conveyor belt 24 to the corresponding station of the flattening guide mechanism 5 at both ends of the protective housing 3, it first contacts the pressure rollers 55 on both sides of the bottom of the slide 52. Under the downward pressure of the return spring 53, the pressure rollers 55 cooperate with the conveyor belt 24 to precisely flatten both sides of the aluminum sheet surface, pressing the warped and protruding parts of the aluminum sheet surface to flatten them, ensuring uniform force for subsequent polishing. The edge pressing rollers 547 of the guide 54 on both sides of the aluminum sheet are attached to the edge pressing rollers 547, which drive the edge pressing rollers 547 to rotate within the frame 546, and then through... The inclined block 545 and the rotating rod 541 drive the pressure cylinder 542 to rotate synchronously, reducing frictional damage between the components and the edge of the aluminum sheet. The buffer spring 548 can adaptably extend and retract, pushing the inclined block 545 to slide along the guide rail 544 in the fan-shaped groove 543, driving the pressure wheel 547 to elastically fit the side of the aluminum sheet, achieving precise positioning and guidance, and completely avoiding the left and right deviation of the aluminum sheet during the conveying process. At the same time, the pressure cylinder 542 rotates with the rotating rod 541, assisting in flattening the edge of the aluminum sheet, ensuring that the aluminum sheet moves smoothly to the polishing station. After being flattened and guided, the aluminum sheet is precisely fed into the polishing station by the conveyor belt 24. At this time, the two sets of motors 63 are powered on synchronously, and the output torque drives the corresponding transmission wheel 64 to rotate. The power is stably transmitted to the transmission wheel 66 through the transmission belt 67, which drives the two transmission shafts 65 to rotate synchronously. This in turn drives the polishing roller 68 and the chip removal roller 69 on the shaft to rotate at high speed. The aluminum sheet first passes through the polishing roller 68 near the feed end. The polishing roller 68 is precisely in contact with the surface of the aluminum sheet and performs high-intensity and uniform polishing to remove impurities and protrusions from the surface of the aluminum sheet, so that the surface of the aluminum sheet reaches the smoothness standard required for non-stick pan production. After polishing, the aluminum sheet continues to move forward with the conveyor belt 24 and passes through the corresponding station of the chip removal roller 69. The chip removal roller 69 rotates at high speed to thoroughly clean the surface of the polished aluminum sheet, completely sweeping away the residual polishing debris attached to the surface of the aluminum sheet, ensuring that the surface of the polished aluminum sheet is clean and free of debris residue that may affect subsequent processing. During the polishing operation, the blower 9 starts simultaneously, generating a directional airflow. The airflow forms a directional chip guiding space inside the enclosed protective housing 3, quickly blowing the polishing roller 68 to grind and the chip sweeping roller 69 to sweep away the generated chips. The chips move directly against the inner wall of the protective housing 3 with the airflow and flow into the chip guide groove 10. The chip guide groove 10, with its shallow upper and deep lower structure, quickly guides the chips to slide down to the chip collection mechanism 4. The chips on the surface of the conveyor belt 24 fall onto the chip guide plate 42. The chip guide groove 43 on the surface of the chip guide plate 42 diverts and guides the chips, preventing a large amount of chips from accumulating and clogging in a local area. At the same time, the support spring 44 vibrates slightly with the operation of the device, causing the chip guide plate 42 to sway slightly, assisting the chips to slide down quickly. After being guided by the chip guide plate 42, all the chips fall smoothly into the chip collection box 41 for storage, ensuring a clean working environment. The polished and chipped aluminum sheet is continuously moved by the conveyor belt 24, moving out of the protective housing 3 and the polishing station, completing all polishing operations.
