Description

Technical Field

[0001] This utility model belongs to the technical field of sanding devices, and specifically relates to a sanding device for the surface of iron sheet used in printing cans. Background Technology

[0002] The core of tinplate can-making technology lies in making various packaging containers from tinplate through printing, cutting, and forming processes. Early processes relied on acid washing or alkali washing to remove the surface oxide layer, but chemical reagents are easy to leave residues, which leads to a decrease in the adhesion of subsequent printing inks. Manual polishing with sandpaper or wire brushes is inefficient, results in uneven surface roughness, and easily scratches the tinplate substrate, affecting printing accuracy.

[0003] During the sanding process of sheet metal, misalignment of the sheet metal may cause the edges of the sheet metal to curl up, bend and crack. The high-speed moving grinding disc may throw out debris, threatening the safety of operators. Severe misalignment may cause equipment vibration or jamming, resulting in accidents such as grinding disc breakage and workpiece flying out. The risk is even higher in automated production lines, where operators need to stop the machine frequently to correct the position of the sheet metal, interrupting the continuous production process and reducing the output per unit time.

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a device for sanding the surface of sheet metal for printing cans, including a frame 1. A coiling component 2 is provided on one side of the frame 1, and an anti-deviation component 3 is provided on the top of the frame 1. A conveying component 4 and a polishing component 5 are respectively provided on the top of the frame 1. A winding component 6 is provided on the other side of the frame 1. The coiling component 2 is used to position the sheet metal coil, the anti-deviation component 3 is used to guide the sheet metal as it moves on the surface of the conveying component 4, the polishing component 5 is used to polish the sheet metal, and the winding component 6 is used to wind up the polished sheet metal.

[0029] After the sheet metal to be processed is loaded onto the outer surface of the uncoiling assembly 2, the sheet metal is passed through the anti-deviation assembly 3. By activating the conveying assembly 4, the sheet metal is moved on top of the conveying assembly 4. The conveying assembly 4 brings the sheet metal to the bottom of the grinding assembly 5. The grinding assembly 5 is activated to grind the sheet metal. After grinding, the sheet metal is wound up by activating the rewinding assembly 6.

[0030] During the sheet metal sanding process, the operator can pass the sheet metal through the anti-deviation component 3 and move it according to the route of the anti-deviation component 3. The drive conveyor component 4 will then carry the sheet metal to the bottom of the sanding component 5 for sanding. During the sanding process, the sheet metal is kept in a fixed position during processing to avoid quality defects, equipment wear and safety hazards caused by deviation. The operator does not need to stop the machine frequently to correct the position of the sheet metal, thus achieving continuous production.

[0031] In one embodiment, the unwinding assembly 2 includes a limiting groove 201. The limiting groove 201 is provided on the top of the frame 1. A first bearing 202 is slidably installed inside the limiting groove 201. There are two sets of the first bearing 202. A first reel 203 is fixedly installed between the two sets of first bearings 202.

[0032] After the sheet metal roll is installed onto the first spool 203, the rotation of the conveyor assembly 4 causes the sheet metal and the first spool 203 to rotate. As the first spool 203 rotates, the first bearing 202 rotates within the limiting groove 201 to reduce friction on the first spool 203.

[0033] In one embodiment, the anti-deviation component 3 includes a guide rail 301, which is fixedly mounted on the top of the frame 1. The guide rail 301 has a slot 302 inside, and a rotating post 303 is inserted into the slot 302.

[0034] By passing the sheet metal through the guide rail 301 and having both sides of the sheet metal contact the rotating post 303 inside the guide rail 301, the sheet metal can be controlled to prevent it from shifting. The rotation of the rotating post 303 inside the slot 302 can reduce the friction between the sheet metal and the rotating post 303.

[0035] In one embodiment, the conveying component 4 includes a drive motor 401, which is fixedly installed inside the frame 1. A first pulley 402 is fixedly installed at the output end of the drive motor 401. A first belt 403 is sleeved on the outer surface of the first pulley 402. There are three sets of first pulleys 402, and a first rotating shaft 404 is fixedly installed inside two sets of first pulleys 402. A conveyor belt 405 is sleeved on the outer surface of the first rotating shaft 404.

[0036] By starting the drive motor 401, the first pulley 402 and the first belt 403 are rotated, which in turn drives the first rotating shaft 404 to rotate. The first rotating shaft 404 drives the conveyor belt 405 to rotate, so that the sheet metal moves on top of the conveyor belt 405.

[0037] In one embodiment, the polishing assembly 5 includes a rotary motor 501, which is fixedly installed inside the frame 1. A second pulley 502 is fixedly installed at the output end of the rotary motor 501. A second belt 503 is sleeved on the outer surface of the second pulley 502. There are three sets of the second pulley 502. A second rotating shaft 504 is fixedly installed inside two sets of the second pulley 502. A second bearing 505 is sleeved at both ends of the second rotating shaft 504. There are two sets of the second rotating shaft 504 and four sets of the second bearing 505. The second bearings are fixedly installed on the top of the frame 1. An abrasive belt 506 is sleeved on the outer surface of the second rotating shaft 504.

[0038] By starting the rotary motor 501, the second pulley 502 and the second belt 503 are rotated, which in turn drives the second rotating shaft 504 to rotate, so as to drive the abrasive belt 506 on the outer surface of the second rotating shaft 504 to rotate and abrade the sheet metal. While the second rotating shaft 504 is rotating, the second bearings 505 installed at both ends of the second rotating shaft 504 also rotate together to reduce the friction between the second rotating shaft 504 and the frame 1.

[0039] In one embodiment, the winding assembly 6 includes a support platform 601, which is fixedly installed on the side of the frame 1. A winding motor 602 is fixedly connected to the top of the support platform 601. A coupling sleeve 603 is fixedly installed at the output end of the winding motor 602. A second reel 604 is threadedly connected to the inside of the coupling sleeve 603. Two sets of third bearings 605 are sleeved on both ends of the second reel 604.

[0040] After the sheet metal is sanded, the winding motor 602 on the top of the support platform 601 is started, which drives the coupling sleeve 603 connected to the output end of the winding motor 602 to rotate. The second winding shaft 604 inside the coupling sleeve 603 rotates together, causing the sheet metal to be wound up. The rotation of the second winding shaft 604 causes the third bearings 605 installed at both ends of the second winding shaft 604 to rotate together, reducing the friction between the second winding shaft 604 and the frame 1.

[0041] In one embodiment, for the frame 1 described above, protective covers 7 are fixedly installed on both sides of the frame 1, and there are two sets of protective covers 7.

[0042] When the drive motor 401 is running, the rotating first belt 403 may suddenly break under conditions such as overload, aging, or improper installation. The protective cover 7 can restrain the flight trajectory of the broken parts to prevent injury to surrounding personnel or damage to other equipment.

[0043] Through the above technical solutions, 1. During the sheet metal grinding process, the operator can pass the sheet metal through the anti-deviation component 3 and move it according to the route of the anti-deviation component 3. The drive conveyor component 4 will carry the sheet metal to the bottom of the grinding component 5 for grinding. During the grinding process, it is ensured that the sheet metal remains in a fixed position during processing, avoiding quality defects, equipment wear and safety hazards caused by deviation. The operator does not need to frequently stop the machine to correct the position of the sheet metal, thus achieving continuous production; 2. By passing the sheet metal through the guide rail 301 and making the two sides of the sheet metal touch the rotating column 303 inside the guide rail 301, the sheet metal can be controlled by the rotating column 303 on both sides of the sheet metal to prevent deviation. While the sheet metal moves according to the route of the guide rail 301, it drives the rotating column 303 to rotate inside the slot 302, which can reduce the friction between the sheet metal and the rotating column 303.
