Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate coating, in particular to an aluminum plate coating device. Background Art

[0002] Laminated aluminum plate refers to a layer of film coated on ordinary aluminum plate to protect the aluminum plate. Most of them are to prevent wear and scratches on the aluminum plate during subsequent processing and transportation. Depending on the type of coating, the purpose to be achieved is different. Some of them are to make the appearance of the aluminum plate more beautiful. The laminated aluminum plate has excellent durability and anti-fouling ability.

[0003] In this regard, China's patent application number: CN202210147376.X discloses an extrusion-type carton laminating machine for avoiding bubbles, including a laminating machine body, an input mechanism, a laminating mechanism, a laminating roller and a tension roller. An input mechanism is provided on the upper part of one side of the laminating machine body, a horizontally arranged driven roller is provided on the upper inner side of the input mechanism, a rotatable active roller is embedded in the upper end face of the laminating machine body below the driven roller, a tension roller for unfolding the film is provided below the laminating roller, a scraping and de-bubble mechanism for pressing and spreading the film is provided on the rear side of the laminating mechanism, a pressing mechanism is provided on the rear side of the scraping and de-bubble mechanism, and two horizontal driven rollers are provided on the inner side of the output mechanism. The extrusion-type carton laminating machine for avoiding bubbles can make the film adhere to the carton board and avoid the generation of bubbles or bulges by setting corresponding mechanisms before and after laminating the carton board.

[0004] The laminating machine can scrape out the bubbles between the plate and the film by setting up two sets of scraping bars rotating in opposite directions. However, the two sets of scraping bars act at the same time. In the process of scraping out the bubbles, the film will be displaced on the plate, making the film covering the plate crooked, affecting the appearance, and causing part of the surface of the plate to be without film, which will affect the subsequent handling and use of the plate.

[0010] Preferably, the fixed frame is installed on the right side of the film roll, the movable plate is located on the inner side of the fixed frame, the length of the movable plate is greater than the width of the aluminum plate body, and the threaded rod, motor, moving block, mounting frame, scraping roller, mounting groove and fixed structure are all provided in two groups.

[0011] Preferably, the output end of the motor is fixedly connected to the threaded rod, and the two groups of threaded rods are respectively threadedly connected to the two groups of moving blocks, and the two groups of moving blocks are installed in the front-to-back direction.

[0012] Preferably, the installation groove is in a "7"-shaped structure, the pulley is installed at the bend inside the installation groove, and the pulley is in contact with the steel wire rope.

[0013] Preferably, the two sets of fixed structures are installed symmetrically, the end of the sliding block is exposed from the side wall of the moving block, one end of the first spring and the second spring are fixedly connected to the inner wall of the installation groove, and the first spring and the second spring are both sleeved on the outside of the wire rope.

[0014] Preferably, the steel wire rope is passed through the interior of the installation groove, and the movable block is slidably installed at the inner bottom end of the installation groove.

[0015] Preferably, the friction pad is located just above the left and right ends of the scraping roller, the bottom surface of the friction pad is arc-shaped, the friction pad cooperates with the scraping roller, and the abutment plate is located on one side of the sliding block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging two groups of alternately movable scraping rollers, the present invention can keep the other group of scraping rollers fixed while one group of scraping rollers rolls to squeeze out the bubbles between the aluminum plate body and the film body, thereby being able to position the film body on the aluminum plate body, and making the film body neatly cover the aluminum plate body, thereby ensuring that the coating of the aluminum plate body is flat and neat, improving the coating effect of the aluminum plate body, and ensuring the user experience of the device.

[0017] A scraping structure and a fixed structure are provided, and the motor is started to drive the threaded rod to rotate. The two sets of threaded rods are respectively threadedly connected with the two sets of moving blocks. Therefore, the rotation of the threaded rod can drive the moving block to move, so that the two sets of moving blocks are fitted with each other and are located on the front side of the middle of the top surface of the aluminum plate main body. Because the length of the movable plate is greater than the width of the aluminum plate main body, the two sets of moving blocks located on the front side of the middle of the top surface of the aluminum plate main body have a certain distance between the front and rear sides of the bottom of the movable plate. The cylinder is started, and the cylinder drives the movable plate to descend, and the movable plate drives the moving block and the scraping roller to descend, so that the two sets of scraping rollers fit the top surface of the conveyor platform and are located in the front position of the top surface of the conveyor platform. At this time, the electric telescopic rod on the front set of moving blocks is started, and the electric telescopic rod drives the push plate to move, so that the push plate moves backward and approaches the sliding block in the front set of moving blocks. The push plate pushes the sliding block, so that the sliding block retracts into the installation groove, and the sliding block squeezes the first spring, and the sliding block reduces the tension on the wire rope, and the second spring is the recovery belt When the movable block moves downward, the movable block pulls the wire rope, so that the wire rope is transmitted on the pulley. At the same time, when the movable block moves downward, it will drive the friction pad to move, so that the friction pad is downwardly close to the scraping roller. When the friction pad fits the scraping roller under the action of the second spring, the scraping roller is subjected to the friction force brought by the friction pad and is fixed on the mounting frame, so that a group of scraping rollers located on the front side remain fixed and can be pressed on the film body to position the film body on the aluminum plate body. The motor is started to move a group of moving blocks located on the rear side. When the moving block moves, the group of scraping rollers on the rear side are driven by the mounting frame to move backward, and the scraping roller fits the film body. When the scraping roller moves, it rolls on the film body. The rolling scraping roller can roll out the bubbles between the film body and the aluminum plate body backward, and can reduce the friction force between the scraping roller and the film body, so as to avoid the scraping roller scraping the film body, so that the film body is deformed and ruptured due to the pulling, and the film body can be kept intact.

[0018] Then start the cylinder to raise the movable plate so that the two sets of scraping rollers are separated from the film body, and start the motor to rotate the threaded rod to move the rear set of moving blocks forward so that the rear set of moving blocks is located at the rear side of the top surface of the aluminum plate body, and move the front set of moving blocks backward so that the two sets of moving blocks fit each other, start the cylinder, and the cylinder drives the movable plate to descend, and the movable plate drives the moving blocks and the scraping rollers to descend, so that the two sets of scraping rollers fit the top surface of the conveyor platform and are located at the rear of the top surface of the conveyor platform, and start the electric telescopic rods on the two sets of moving blocks to make the front set of abutment plates move away from the moving blocks. At this time, the sliding block loses the function of the abutment plates, that is, it will be under the action of the first spring. The side wall of the moving block is reset downward, and the sliding block pulls the wire rope, and the wire rope pulls the movable block, so that the friction pad is separated from the scraping roller, that is, the limit of the front group of scraping rollers is released, and at the same time, the abutment plate on the rear group of moving blocks approaches the sliding block, so that the sliding block is retracted into the rear group of moving blocks. As described above, the rear group of scraping rollers is fixed and limited, and the motor is started to move the front group of moving blocks. When the moving block moves, the front group of scraping rollers are driven forward by the mounting frame. The scraping roller fits the film body, and the scraping roller rolls on the film body when it moves. The rolling scraping roller can roll out the bubbles between the film body and the aluminum plate body forward;

[0019] In this way, the two sets of scraping rollers can alternately press and position the film body and roll out the bubbles in the film body, and reduce damage to the film body, which can effectively improve the effect of covering the film body on the aluminum plate body and ensure the quality of the product.

Through the fixing structure 3, when one set of scraping rollers 28 rolls to roll out the bubbles, the other set of scraping rollers 28 can be fixed, so that the scraping rollers 28 press the film body 13 to fix the film body 13 on the top surface of the aluminum plate body 11, avoiding displacement of the film body 13 when rolling out the bubbles in the film body 13, and keeping the film body 13 laid and moved on the aluminum plate body 11, affecting the coating effect of the aluminum plate body 11.

[0034] Furthermore, the fixed frame 21 is installed on the right side of the film reel 12, and the movable plate 23 is located on the inner side of the fixed frame 21.

The movable plate 23 provides a guide limit for the movement of the scraping roller 28. The setting of the two groups of threaded rods 24, the motor 25, the moving block 26, the mounting frame 27, the scraping roller 28, the mounting groove 29 and the fixed structure 3 can realize the alternating movement of the two groups of scraping rollers 28, and when one group of scraping rollers 28 is moving, the other group of scraping rollers 28 remains fixed, thereby improving the use experience.

[0035] Furthermore, the output end of the motor 25 is fixedly connected to the threaded rod 24, and the two groups of threaded rods 24 are respectively threadedly connected to the two groups of moving blocks 26. The two groups of moving blocks 26 are installed in the front-to-back direction. The motor 25 provides power for the rotation of the threaded rod 24, and the rotation of the threaded rod 24 can drive the movement of the moving blocks 26. The setting of the two groups of moving blocks 26 enables the two groups of scraping rollers 28 to grind out bubbles in the front-to-back direction, thereby reducing the moving distance and improving efficiency.

[0036] Furthermore, the mounting groove 29 is in a "7"-shaped structure, and the pulley 33 is installed at the bend inside the mounting groove 29. The pulley 33 fits the steel wire rope 34. The pulley 33 can reduce the friction force on the steel wire rope 34 when it moves inside the "7"-shaped mounting groove 29, thereby ensuring that the sliding block 31, i.e., the movable block 35, moves smoothly.

[0037] Furthermore, the two sets of fixed structures 3 are installed symmetrically, the end of the sliding block 31 is exposed from the side wall of the moving block 26, one end of the first spring 32 and the second spring 37 are fixedly connected to the inner wall of the mounting groove 29, the first spring 32 and the second spring 37 are both sleeved on the outside of the wire rope 34, the sliding block 31 can be telescopic and movable in the moving block 26, and the first spring 32 and the second spring 37 provide power for the sliding block 31 and the movable block 35 to reset in the mounting groove 29.

[0038] Furthermore, the wire rope 34 is passed through the interior of the installation groove 29, and the movable block 35 is slidably installed at the inner bottom end of the installation groove 29. The wire rope 34 can move in the installation groove 29, and the movable block 35 is a movable guide limiter for the friction pad 36 on the inner side of the installation groove 29.

[0039] Furthermore, the friction pad 36 is located on the upper side of the left and right ends of the scraping roller 28, the bottom surface of the friction pad 36 is arc-shaped, the friction pad 36 and the scraping roller 28 cooperate with each other, the abutment plate 39 is located on one side of the sliding block 31, and the friction pad 36 can fit the scraping roller 28 to fix the scraping roller 28 on the mounting frame 27, so that the scraping roller 28 can press the film body 13 down on the top surface of the aluminum plate body 11, fix the film body 13 on the aluminum plate body 11, avoid the film body 13 from shifting between the aluminum plate body 11 and the scraping roller 28, and make the laying of the film body 13 bend.

[0040] Working principle: When in use, the aluminum plate body 11 is placed on the conveying platform 1, and the aluminum plate body 11 can be conveyed from left to right through the conveying platform 1, and the film body 13 is laid on the top surface of the aluminum plate body 11;

[0041] The motor 25 is started to drive the threaded rod 24 to rotate. The two groups of threaded rods 24 are respectively threadedly connected with the two groups of moving blocks 26. Therefore, the rotation of the threaded rod 24 can drive the moving blocks 26 to move, so that the two groups of moving blocks 26 fit each other and are located on the front side of the middle of the top surface of the aluminum plate body 11. Because the length of the movable plate 23 is greater than the width of the aluminum plate body 11, the two groups of moving blocks 26 located on the front side of the middle of the top surface of the aluminum plate body 11 are at a certain distance from the front and rear sides of the bottom of the movable plate 23.

[0042] Start the cylinder 22, which drives the movable plate 23 to descend, and the movable plate 23 drives the moving block 26 and the scraping roller 28 to descend, so that the two sets of scraping rollers 28 are in contact with the top surface of the conveying platform 1 and are located at the front of the top surface of the conveying platform 1;

[0043] At this time, the electric telescopic rod 38 on the front set of moving blocks 26 is started, and the electric telescopic rod 38 drives the stop plate 39 to move, so that the stop plate 39 moves backward close to the sliding block 31 in the front set of moving blocks 26, and the stop plate 39 pushes the sliding block 31, so that the sliding block 31 retracts into the installation groove 29, and the sliding block 31 squeezes the first spring 32, and the sliding block 31 reduces the pulling force on the wire rope 34, and the second spring 37 is restored to drive the movable block 35 to descend, and the movable block 35 pulls the wire rope 34, so that the wire rope 34 is pulled back. 4 is transmitted on the pulley 33, and when the movable block 35 descends, it drives the friction pad 36 to move, so that the friction pad 36 moves downward to approach the scraping roller 28. When the friction pad 36 is in contact with the scraping roller 28 under the action of the second spring 37, the scraping roller 28 is subjected to the friction force brought by the friction pad 36 and is fixed on the mounting frame 27, so that the group of scraping rollers 28 located at the front side remains fixed and can be pressed on the film body 13, so that the film body 13 is positioned at the covering position on the aluminum plate body 11;

[0044] The motor 25 is started to move a group of moving blocks 26 at the rear side. When the moving blocks 26 move, they drive a group of scraping rollers 28 at the rear side to move backwards through the mounting frame 27. The scraping rollers 28 fit the film body 13. When the scraping rollers 28 move, they roll on the film body 13. The rolling scraping rollers 28 can roll out the bubbles between the film body 13 and the aluminum plate body 11 backwards, and can reduce the friction between the scraping rollers 28 and the film body 13, so as to avoid the scraping rollers 28 scraping the film body 13, so that the film body 13 is pulled and deformed and ruptured, and the film body 13 can be kept intact.

[0045] Then, the cylinder 22 is started to raise the movable plate 23, so that the two groups of scraping rollers 28 are separated from the film body 13, and the motor 25 is started to rotate the threaded rod 24, so that the rear group of moving blocks 26 are moved forward, so that the rear group of moving blocks 26 are located at the rear side of the top surface of the aluminum plate body 11, and the front group of moving blocks 26 are moved backward, so that the two groups of moving blocks 26 are attached to each other;

[0046] Start the cylinder 22, which drives the movable plate 23 to descend, and the movable plate 23 drives the moving block 26 and the scraping roller 28 to descend, so that the two sets of scraping rollers 28 are attached to the top surface of the conveying platform 1 and are located at the rear of the top surface of the conveying platform 1;

[0047] The electric telescopic rods 38 on the two groups of moving blocks 26 are started, so that the front group of abutment plates 39 are moved away from the moving blocks 26. At this time, the sliding block 31 loses the effect of the abutment plates 39, that is, it will reset to the side wall of the moving block 26 under the effect of the first spring 32, and the sliding block 31 will pull the wire rope 34, and the wire rope 34 will pull the movable block 35, so that the friction pad 36 is separated from the scraping roller 28, that is, the limit of the front group of scraping rollers 28 is released, and at the same time, the abutment plates 39 on the rear group of moving blocks 26 are close to the sliding block 31, so that the sliding block 31 is retracted into the rear group of moving blocks 26. As above, the rear group of scraping rollers 28 is fixed and limited;

[0048] The motor 25 is started to move a group of moving blocks 26 located at the front side. When the moving blocks 26 move, they drive a group of scraping rollers 28 at the front side to move forward through the mounting frame 27. The scraping rollers 28 are attached to the film body 13. When the scraping rollers 28 move, they roll on the film body 13. The rolling scraping rollers 28 can roll out the bubbles between the film body 13 and the aluminum plate body 11.

[0049] In this way, the two groups of scraping rollers 28 can alternately press and position the film body 13 and roll out the bubbles in the film body 13, and reduce damage to the film body 13, which can effectively improve the effect of covering the film body 13 on the aluminum plate body 11 and ensure the quality of the product.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
