Description

Technical Field

[0001] This invention relates to the field of aluminum plate processing technology, specifically to an aluminum plate surface treatment device. Background Technology

[0002] Aluminum sheets, with their lightweight, corrosion resistance, excellent thermal conductivity, and good processing performance, are widely used in various fields such as building decoration, automobile manufacturing, electronic equipment, and aerospace. In the aluminum sheet production process, surface grinding is an indispensable and crucial step. Its core purpose is to remove the oxide layer, impurities generated during production, unevenness, and burrs from the aluminum sheet surface, improving the flatness and smoothness of the surface. This ensures the smooth progress of subsequent deep processing steps such as coating, splicing, and stamping, thereby guaranteeing the quality and service life of the final product. Therefore, specialized aluminum sheet surface treatment equipment is needed to achieve efficient and stable grinding operations.

[0003] Existing aluminum plate surface treatment devices typically include a processing box, a conveying mechanism, a grinding mechanism, and a pressing mechanism. The working process is roughly as follows: the aluminum plate to be processed is conveyed to the grinding area inside the processing box by the conveying mechanism; the pressing mechanism drives the grinding roller in the grinding mechanism to move downward, so that the grinding roller contacts the surface of the aluminum plate and applies a certain pressure; at the same time, the grinding mechanism drives the grinding roller to rotate at high speed, using rotational friction to grind the surface of the aluminum plate; after grinding is completed, the aluminum plate is sent out of the processing box by the conveying mechanism.

[0004] However, existing devices of this type cannot flexibly adjust the initial position and pressure threshold of the grinding limit according to the different thicknesses of the aluminum plate to be processed. The downward pressure of the grinding roller cannot be adaptively adjusted. When the grinding pressure exceeds the range that the aluminum plate can withstand, it cannot effectively buffer and adjust the downward pressure in time, which can easily lead to scratches and pressure damage on the surface of the aluminum plate. It is difficult to ensure the stability and consistency of grinding aluminum plates of different specifications and cannot adapt to the processing needs of multi-specification aluminum plates. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum plate surface treatment device, which aims to improve the problem that existing devices cannot adaptively adjust the downward pressure of the grinding roller according to the different thicknesses of the aluminum plate to be processed.

[0006] The objective of this invention is achieved through the following technical solution: an aluminum plate surface treatment device, comprising a processing box, wherein a pressing mechanism and a rotating mechanism are provided on the top of the processing box, a grinding roller is provided at the bottom of the pressing mechanism, a protective mechanism is provided inside the processing box, and a conveyor belt is provided at the bottom of the processing box; The protective mechanism includes a limiting platform, which is slidably connected inside the processing box. Multiple sliding rods are fixedly connected inside the processing box. The bottom ends of the limiting platform are slidably connected to the outside of the sliding rods. A pressure ring is fixedly connected to the bottom of the limiting platform. A pre-tightening ring is magnetically sleeved on the outside of the sliding rods. A pre-tightening spring is provided between the pre-tightening ring and the pressure ring. The protective mechanism also includes a transmission rod that is slidably connected inside the processing box. One end of the transmission rod is fixedly connected to the outside of the lower pressure ring, and the other end of the transmission rod is fixedly connected to a trigger platform. A connecting rod is fixedly connected inside the trigger platform, and the other end of the connecting rod is hinged to two hinge plates.

[0007] As a further description of the above technical solution: The protective mechanism also includes multiple cams rotatably connected to the outside of the processing box, and a feedback plate slidably connected inside the processing box; As a further description of the above technical solution: The bottom ends of the feedback plate are both set as arc surfaces, and their shapes are adapted to the outer shape of the cam. As a further description of the above technical solution: The pressing mechanism includes a cylinder fixedly connected to the top of the processing box, a support platform fixedly connected to the output end of the cylinder, a plurality of connecting pins slidably connected inside the support platform, and a buffer spring sleeved on the outside of the connecting pins. As a further description of the above technical solution: The outer side of the feedback plate is slidably connected to the outer side of the connecting pile, and the top of the feedback plate abuts against the bottom of the buffer spring. As a further description of the above technical solution: The processing box has three sliding grooves inside. The two ends of the grinding roller are slidably connected to the inside of the first sliding groove, the outer side of the transmission rod is slidably connected to the inside of the second sliding groove, and the outer side of the feedback plate is slidably connected to the inside of the third sliding groove. As a further description of the above technical solution: The rotating mechanism includes a double-headed motor fixedly connected to the top of the rotating box. Both output ends of the double-headed motor are equipped with belt pulley transmission components, and the other end of the belt pulley transmission component is located at the end of the grinding roller. The belt in the belt pulley transmission component is made of highly elastic rubber. A limit groove is opened inside the processing box, and the belt in the belt pulley transmission component is slidably connected inside the limit groove. As a further description of the above technical solution: The conveyor belt includes a base fixedly connected to the bottom of the processing box, a transmission belt rotatably connected to the top of the base, a conveyor roller provided on the inner side of the transmission belt, and a drive motor installed on the outer side of the transmission belt.

[0008] Compared with the prior art, the advantages of the present invention are as follows: 1. By adjusting the preload of the preload spring through the preload ring, the initial position and resistance of the limiting table are adjusted to adapt to the processing requirements of aluminum plates of different thicknesses. Then, the limiting table drives the transmission rod to slide down, which in turn drives the trigger table and connecting rod to descend. The connecting rod pulls the hinge plate to rotate the cam. The cam presses upward against the feedback plate, which adjusts the preload of the buffer spring, thereby adjusting the downward pressure of the grinding roller. This achieves the beneficial effects of flexibly adapting to the processing of aluminum plates of different specifications, effectively avoiding excessive grinding pressure that could damage the aluminum plate material, and ensuring the stability and consistency of the aluminum plate surface grinding.

[0009] 2. The high-elasticity rubber belt, combined with a dual-head motor of the rotating mechanism, drives the grinding roller to rotate at high speed. Simultaneously, the pressing mechanism drives the grinding roller to press down. The belt's elasticity resists the weight of the grinding roller to maintain stable transmission. The conveyor belt then smoothly moves the aluminum plate into and out of the processing box and positions it precisely. The pressing mechanism and the protective mechanism work together to achieve the beneficial effects of high aluminum plate surface grinding efficiency, smooth and jam-free transmission process, continuous batch processing of aluminum plates, significantly reduced manual intervention, and stable and reliable processing quality.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 8 The diagram shown is a schematic representation of an embodiment of an aluminum plate surface treatment device provided by the present invention. This embodiment provides an aluminum plate surface treatment device, including a processing box 1. The processing box 1 provides a mounting carrier for all components of the device, ensuring stable arrangement of each structure and providing a closed processing space for aluminum plate surface treatment operations, avoiding interference from debris or flying processing chips during operation. A pressing mechanism 2 and a rotating mechanism 4 are provided on the top of the processing box 1. The pressing mechanism 2 provides downward pressure to the grinding roller 3, pushing the grinding roller 3 close to the aluminum plate surface, ensuring that the grinding roller 3 can fully contact the aluminum plate surface, meeting the pressure requirements of the grinding operation. The pressing amplitude of the grinding roller 3 can be flexibly adjusted. The pressing mechanism 2... A grinding roller 3 is installed at the bottom, which directly contacts the surface of the aluminum plate. The high-speed rotation generates friction to grind the surface of the aluminum plate, removing impurities or defects and improving the flatness and smoothness of the aluminum plate surface. The processing box 1 is equipped with a protective mechanism 5 inside, which protects the aluminum plate during the processing, limits the positional deviation of the aluminum plate, adjusts the grinding pressure, and avoids damage to the aluminum plate due to excessive grinding pressure, ensuring the stability and safety of the grinding operation. A conveyor belt 6 is installed at the bottom of the processing box 1, which realizes the function of conveying the aluminum plate to be processed, transporting the aluminum plate to be processed to the designated grinding position, and simultaneously conveying the ground aluminum plate out of the processing box 1, realizing continuous processing operation.

[0013] The pressing mechanism 2 includes a cylinder 201 fixedly connected to the top of the processing box 1. The cylinder 201 serves as the power component of the pressing mechanism 2, providing stable downward pressure to drive the support platform 202 and the grinding roller 3 to move up and down, precisely controlling the pressing stroke and pressure of the grinding roller 3. The output end of the cylinder 201 is fixedly connected to the support platform 202, which supports the connecting pile 203 and the buffer spring 204, providing them with mounting support, transmitting the downward pressure of the cylinder 201, and driving the connecting pile 203 and the grinding roller 3 to move synchronously, ensuring the stability of the pressing action. The internal sliding connection of 202 has multiple connecting pins 203. The connecting pins 203 cooperate with the support platform 202 to install buffer springs 204, which restrict the installation position of the buffer springs 204, transmit the elastic force of the buffer springs 204, assist in adjusting the downward pressure of the grinding roller 3, and ensure uniform pressure transmission. The outer side of the connecting pins 203 is fitted with buffer springs 204. The buffer springs 204 adjust the downward pressure of the grinding roller 3. When the grinding pressure is too high, a reverse elastic force is generated to reduce the pressure of the grinding roller 3 on the aluminum plate or push the grinding roller 3 upward to avoid damaging the aluminum plate, while maintaining stable grinding pressure.

[0014] The rotating mechanism 4 includes a dual-head motor 401 fixedly connected to the top of the rotating box. The dual-head motor 401 provides power to the belt pulley drive component 402, and transmits power synchronously through two output ends to ensure that the grinding roller 3 is subjected to uniform force and rotates at the same speed, thus ensuring uniform grinding effect. Both output ends of the dual-head motor 401 are equipped with belt pulley drive components 402, which transmit the power of the dual-head motor 401 to the end of the grinding roller 3, driving the grinding roller 3 to rotate, ensuring the stability and continuity of power transmission. The other end of the belt pulley drive component 402 is located on the grinding roller. At the end of 3, the belt in the pulley drive component 402 is made of high-elasticity rubber. The high-elasticity rubber belt can be stretched as the grinding roller 3 presses down, adapting to the up and down movement of the grinding roller 3. At the same time, it uses its own elasticity to resist the weight of the grinding roller 3, maintaining the stability of the transmission process and avoiding transmission jamming. A limit groove 515 is opened inside the processing box 1. The limit groove 515 restricts the movement trajectory of the belt in the pulley drive component 402, preventing the belt from deviating or falling off during the transmission process, ensuring the stability and accuracy of the belt transmission. The belt in the pulley drive component 402 is slidably connected inside the limit groove 515.

[0015] The conveyor belt 6 includes a base 601 fixedly connected to the bottom of the processing box 1. The base 601 provides mounting support for the transmission belt 602 and the conveyor roller 603, fixes the position of the conveyor belt 6, ensures the stability of the conveyor belt 6 during operation, and avoids shaking or deviation. The transmission belt 602 is rotatably connected to the top of the base 601. The transmission belt 602 directly carries the aluminum plate and drives the aluminum plate to move smoothly, realizing the infeed and outfeed conveying and positioning of the aluminum plate, ensuring the stability of the aluminum plate during processing, and facilitating grinding operations. The inner side of the transmission belt 602 is provided with a conveyor roller 603, which assists the operation of the transmission belt 602, supports the bottom of the transmission belt 602, reduces the friction of the transmission belt 602 during operation, ensures the smooth and stable operation of the transmission belt 602, and improves the conveying efficiency. The outer side of the transmission belt 602 is equipped with a drive motor 604, which provides power to the transmission belt 602, drives the transmission belt 602 to rotate at a uniform speed, controls the conveying speed of the conveyor belt 6, ensures accurate and stable conveying of the aluminum plate, and adapts to continuous processing requirements.

[0016] The protective mechanism 5 includes a limiting platform 501, which restricts the edge position of the aluminum plate to prevent it from shifting or lifting during grinding, ensuring positional stability and improving grinding consistency. The limiting platform 501 is slidably connected inside the processing box 1. Multiple sliding rods 502 are fixedly connected inside the processing box 1. The sliding rods 502 provide sliding guidance for the limiting platform 501, restricting its movement trajectory and ensuring smooth up-and-down movement. This ensures stable operation of the limiting and protective functions. The bottom ends of the limiting platform 501 are slidably connected to the outside of the sliding rods 502. A pressure ring 503 is fixedly connected to the bottom of the limiting platform 501, which, in conjunction with a preload spring 505, transmits... The preload force drives the limiting stage 501 to move synchronously, assisting in adjusting the initial position and resistance of the limiting stage 501 to adapt to the processing requirements of aluminum plates of different thicknesses. The outer side of the slide rod 502 is magnetically fitted with a preload ring 504. The preload ring 504 is movable and adjustable, changing the compression of the preload spring 505, thereby adjusting the preload spring force of the preload spring 505, realizing flexible adjustment of the initial position and resistance of the limiting stage 501. A preload spring 505 is set between the preload ring 504 and the lower pressure ring 503. The preload spring 505 provides preload spring force to determine the initial position and resistance of the limiting stage 501. When the grinding pressure exceeds the threshold, compression can occur, driving the limiting stage 501 to move and triggering subsequent pressure adjustment actions. The protective mechanism 5 also includes a transmission rod 506 slidably connected inside the processing box 1. The transmission rod 506 transmits the movement of the limiting table 501, and transmits the up-and-down movement of the limiting table 501 to the trigger table 507, providing a guarantee for the transmission of pressure adjustment action and ensuring smooth linkage of the protective mechanism 5. One end of the transmission rod 506 is fixedly connected to the outside of the lower pressure ring 503, and the other end of the transmission rod 506 is fixedly connected to the trigger table 507. The trigger table 507 carries the connecting rod 508, transmits the movement of the transmission rod 506, drives the connecting rod 508 to move up and down, and triggers the hinge plate 509 and the cam 510. The action initiates the pressure regulation process. A connecting rod 508 is fixedly connected inside the trigger table 507. The connecting rod 508 connects the trigger table 507 and the hinge plate 509, transmitting the movement of the trigger table 507 and driving the hinge plate 509 to move. This ensures that the various components of the protective mechanism 5 move in unison, guaranteeing smooth pressure regulation. Two hinge plates 509 are hinged to the other end of the connecting rod 508. The hinge plates 509 cooperate with the connecting rod 508 to transmit the action, driving the cam 510 to rotate. This converts the up-and-down movement of the connecting rod 508 into the rotational movement of the cam 510, realizing the conversion and transmission of the pressure regulation action.

[0017] The protective mechanism 5 also includes multiple cams 510 rotatably connected to the outside of the processing box 1. The cams 510 rotate and press the feedback plate 511, pushing the feedback plate 511 to move up and down, thereby adjusting the preload of the buffer spring 204 and adjusting the downward pressure of the grinding roller 3 to avoid damaging the aluminum plate. The feedback plate 511 is slidably connected inside the processing box 1. The feedback plate 511 receives the pressing action of the cam 510 and transmits it to the buffer spring 204. Adjusting the preload of the buffer spring 204, it then reverses and adjusts the downward pressure of the grinding roller 3 to ensure that the grinding pressure is within a reasonable range. Both ends of the bottom of the feedback plate 511 are set as arc surfaces. The arc surface at the bottom of the feedback plate 511 is adapted to the outer shape of the cam 510 to ensure that the cam 510 can smoothly press the feedback plate 511 when rotating, avoiding jamming during the pressing process, ensuring smooth pressure adjustment, and the shape is adapted to the outer shape of the cam 510. The outer side of the feedback plate 511 is slidably connected to the outer side of the connecting pile 203, and the top of the feedback plate 511 abuts against the bottom of the buffer spring 204.

[0018] The processing box 1 has three sliding grooves: groove 1 512, groove 2 513, and groove 3 514. Groove 1 512 provides sliding guides for both ends of the grinding roller 3, limiting the movement trajectory of the grinding roller 3 and ensuring that the grinding roller 3 can move up and down smoothly, thus ensuring the stability and accuracy of the grinding operation. Groove 2 513 provides sliding guides for the transmission rod 506, limiting the movement trajectory of the transmission rod 506 and ensuring that the transmission rod 506 can slide up and down smoothly, thus ensuring the stability and smoothness of the action transmission. Groove 3 514 provides sliding guides for the feedback plate 511, limiting the movement trajectory of the feedback plate 511 and ensuring that the feedback plate 511 can move up and down smoothly, thus ensuring the accuracy of the preload adjustment of the buffer spring 204. Both ends of the grinding roller 3 are slidably connected to the inside of groove 1 512, the outside of the transmission rod 506 is slidably connected to the inside of groove 2 513, and the outside of the feedback plate 511 is slidably connected to the inside of groove 3 514. Working principle: Before the operation begins, the pre-tightening ring 504 is moved according to the thickness of the aluminum plate to be processed, and the pre-tightening force of the pre-tightening spring 505 is adjusted. This adjusts the initial position and resistance of the limiting stage 501, so that the device can adapt to the processing requirements of the current batch of aluminum plates.

[0019] When the entire aluminum plate surface treatment device is started, the conveyor belt 6 enters the running state first, and the transmission belt 602 starts to rotate under the action of the drive motor 604, which drives the aluminum plate processing material to smoothly enter the device from one side of the processing box 1. Through the stable conveying of the conveyor belt 6, the aluminum plate is accurately transported to the designated processing position directly below the grinding roller 3.

[0020] Once the aluminum plate reaches the designated position, the pressing mechanism 2 initiates the pressing action, and simultaneously the rotating mechanism 4 starts operating. The dual-head motor 401 begins to run, and its two output ends transmit power to the ends of the grinding roller 3 via the belt pulley transmission component 402, causing the grinding roller 3 to rotate at high speed. Because the belt in the belt pulley transmission component 402 is made of highly elastic rubber, it can be stretched to accommodate the pressing stroke as the grinding roller 3 moves downward with the pressing mechanism 2. At the same time, the elasticity of the material itself can resist the weight of the grinding roller 3, maintaining the stability of the transmission process.

[0021] As the pressing mechanism 2 continuously drives the grinding roller 3 downwards towards the aluminum plate, when the pressing stroke of the grinding roller 3 or the applied pressure exceeds a pre-adjusted threshold, the limiting platform 501 begins to move downwards, causing the connected transmission rod 506 to slide down synchronously. The downward movement of the transmission rod 506 further causes the trigger platform 507 to descend, and the descent of the trigger platform 507 in turn causes the connecting rod 508 to move downwards synchronously. The downward movement of the connecting rod 508 pulls the hinge plate 509, causing the cam 510 to rotate.

[0022] After the cam 510 rotates, its outer arc surface presses upward against the feedback plate 511, pushing the feedback plate 511 upward. The upward movement of the feedback plate 511 acts on the buffer spring 204. Adjusting the preload of the buffer spring 204, the reverse elastic force generated by the buffer spring 204 is transmitted to the support platform 202 of the pressing mechanism 2, thereby reducing the downward pressure of the grinding roller 3, or pushing the grinding roller 3 upward when the pressure is too high, thus avoiding damage to the aluminum plate material by the grinding roller 3.

[0023] During the polishing process, the rotating mechanism 4 continuously drives the polishing roller 3 to rotate at high speed. The polishing roller 3 comes into contact with the surface of the aluminum plate, generating friction and polishing the surface of the aluminum plate. At the same time, the conveyor belt 6 maintains a stable operating state to ensure that the position of the aluminum plate does not shift during the polishing process, providing stable support for the polishing operation.

[0024] When the downward pressure of the grinding roller 3 returns to the threshold range, the limit table 501 stops moving downward, and the transmission rod 506, trigger table 507, connecting rod 508, hinge plate 509, and cam 510 also stop moving. The feedback plate 511 maintains its current position under the action of the buffer spring 204, keeping the preload of the buffer spring 204 stable, ensuring that the pressure between the grinding roller 3 and the aluminum plate surface is within a suitable range, so that the grinding operation can continue stably.

[0025] After the aluminum plate surface is polished, the pressing mechanism 2 drives the polishing roller 3 to return to its original position. The support platform 202 drives the connecting pile 203 and the feedback plate 511 to move upward synchronously. The buffer spring 204 gradually returns to its original length during the upward movement of the support platform 202. The rotating mechanism 4 stops operating, and the polishing roller 3 stops rotating. The high-elasticity rubber belt contracts under its own elasticity and returns to its initial state.

[0026] The conveyor belt 6 continues to operate, smoothly conveying the polished aluminum plate out of the device from the other side of the processing box 1, while simultaneously bringing the next aluminum plate to be processed into the processing box 1. The above steps are repeated to achieve continuous aluminum plate surface polishing operations until all aluminum plates to be processed are completed.
