Abstract
Description
Technical Field
[0001] This utility model relates to the field of rust-proof paper processing technology, specifically to a rust-proof paper trimming device. Background Technology
[0002] Rust-proof paper is a paper material used to prevent metals from rusting. Its base material is usually packaging kraft paper, and it is suitable for various metal materials and products.
[0003] However, in the existing rust-proof paper trimming process, most trimming blade holders are fixedly set on the trimming device. When trimming rust-proof paper of different widths, the trimming blade cannot be adjusted, which easily leads to excessive trimming or incomplete trimming, resulting in product waste. In order to solve the above problems, the inventor proposes a rust-proof paper trimming device. Utility Model Content
[0004] To address the problem that most edge-cutting blade holders are fixedly mounted on the edge-cutting device during the edge-cutting process of rust-proof paper, making it impossible to adjust the edge-cutting blade when cutting rust-proof paper of different widths, the purpose of this utility model is to provide an edge-cutting device for rust-proof paper.
[0005] To solve the above technical problems, this utility model adopts the following technical solution: a rust-proof paper trimming device, including a base plate, a fixed frame fixedly mounted on the top surface of the base plate, a second motor mounted on the top surface of the fixed frame, a rotating rod fixedly mounted on the output end of the second motor, first fixed ears fixedly mounted on both sides of the rotating rod, a guide rod hinged and rotatably mounted in the first fixed ears, a vertical plate slidably mounted on the bottom surface of the fixed frame, a movable plate fixedly mounted on the top surface of the vertical plate, the movable plate slidably mounted in the fixed frame, a second fixed ear fixedly mounted on one side of the movable plate, the other end of the guide rod hinged and rotatably mounted in the second fixed ear, a rotating shaft rotatably inserted in the vertical plate, a first roller fixedly mounted on the outer surface of the rotating shaft, a cutter fixedly mounted on the outer surface of the rotating shaft between the first rollers, and a cutter mounted on one side of the vertical plate. Equipped with a third motor, the output end of which is fixedly connected to a rotating shaft, an auxiliary rod is rotatably mounted on one side of the vertical plate, and a second roller is fixedly mounted on the outer surface of the auxiliary rod. First, the rust-proof paper to be cut is wound around the surface of the unwinding roller, and then passed between the first and second conveying rollers. By turning on the second motor, the rotating rod is rotated, causing one end of the guide rod to rotate in the first fixed ear and the other end to rotate in the second fixed ear. Then, the moving plate and the vertical plate can slide in the fixed frame, so that the two cutters can move relative to each other. At this time, the first and second rollers are close to the edge cutting position of the rust-proof paper, and the two cutters are located at the edge cutting position of the rust-proof paper. This makes it easy to adjust according to different widths of rust-proof paper, so that the cutters can be aligned with the edge cutting position of the rust-proof paper, avoiding product waste.
[0006] By turning on the first motor, the take-up roller rotates to take up the rust-proof paper after the edges are cut. At the same time, the third motor is turned on, which causes the shaft to drive the first roller to rotate and the cutter to cut the edge of the rust-proof paper.
[0007] After cutting a certain distance, the first and third motors are stopped. The workers then wind the cut waste edges onto the take-up roller, and then turn the first and third motors back on. When the shaft rotates, it drives the drive wheel to rotate. The drive wheel and the driven wheel are connected by a belt drive, which in turn makes the take-up roller rotate. This facilitates the collection of the cut waste edges and prevents them from falling messily onto the base plate. After the cutting is completed, the nut is turned to remove it from the outer surface of the threaded part. At the same time, the take-up roller is removed so that the collected waste edges can be centrally processed.
[0008] Preferably, a limiting plate is fixedly provided on one side of the vertical plate, a limiting rod rotatably passes through the limiting plate, a finishing roller is movably sleeved on the outer surface of the limiting rod, a baffle is fixedly sleeved on the outer surface of the limiting rod, an insert rod is fixedly provided on one side of the baffle, a slot is opened in the finishing roller, the insert rod is movably inserted into the finishing roller, a threaded part is provided on the outer surface of the limiting rod, a nut is threaded on the outer surface of the threaded part, a driving wheel is fixedly sleeved on the outer surface of the rotating shaft, a driven wheel is fixedly sleeved on the outer surface of the limiting rod, and a belt is connected between the driving wheel and the driven wheel.
[0009] Preferably, a first ear plate is fixedly provided on the top surface of the base plate, and a first conveying roller is rotatably connected inside the first ear plate. A second ear plate is fixedly provided on the bottom surface of the fixed frame, and a second conveying roller is rotatably connected inside the second ear plate.

[0011] 1. In this utility model, the vertical plate can slide within the fixed frame, allowing the two cutters to move relative to each other. This facilitates adjustment according to different widths of rust-proof paper, ensuring that the cutters are aligned with the edge of the rust-proof paper and preventing product waste.
[0012] 2.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figure 1-4As shown, this utility model provides a rust-proof paper trimming device, including a base plate 1, a fixed frame 2 fixedly mounted on the top surface of the base plate 1, a second motor 21 mounted on the top surface of the fixed frame 2, a rotating rod 22 fixedly mounted on the output end of the second motor 21, first fixed ears 23 fixedly mounted on both sides of the rotating rod 22, a guide rod 26 hinged and rotatably mounted inside the first fixed ears 23, a vertical plate 3 slidably mounted on the bottom surface of the fixed frame 2, a movable plate 24 fixedly mounted on the top surface of the vertical plate 3, the movable plate 24 slidably mounted inside the fixed frame 2, a second fixed ear 25 fixedly mounted on one side of the movable plate 24, the other end of the guide rod 26 hinged and rotatably mounted inside the second fixed ear 25, a rotating shaft 32 rotatably inserted inside the vertical plate 3, a first roller 33 fixedly mounted on the outer surface of the rotating shaft 32, and a cutter 34 fixedly sleeved between the first rollers 33 on the outer surface of the rotating shaft 32. A third motor 31 is installed on one side of the vertical plate 3. The output end of the third motor 31 is fixedly connected to the rotating shaft 32. An auxiliary rod 35 is rotatably provided on one side of the vertical plate 3. A second roller 36 is fixedly sleeved on the outer surface of the auxiliary rod 35. By turning on the second motor 21, the rotating rod 22 is rotated, causing one end of the guide rod 26 to rotate in the first fixed ear 23 and the other end to rotate in the second fixed ear 25. Then the moving plate 24 and the vertical plate 3 can slide in the fixed frame 2, so that the two cutters 34 can move relative to each other, which facilitates adjustment according to different widths of rust-proof paper, so that the cutter 34 can be aligned with the edge cutting position of the rust-proof paper, avoiding product waste. By turning on the third motor 31, the rotating shaft 32 drives the first roller 33 to rotate, and the cutter 34 rotates to cut the edge of the rust-proof paper.
[0021] A limiting plate 4 is fixedly provided on one side of the vertical plate 3. A limiting rod 41 is rotatably passed through the limiting plate 4. A finishing roller 46 is movably sleeved on the outer surface of the limiting rod 41. A baffle 44 is fixedly sleeved on the outer surface of the limiting rod 41. An insert rod 45 is fixedly provided on one side of the baffle 44. A slot 47 is opened in the finishing roller 46. The insert rod 45 is movably inserted into the finishing roller 46. A threaded part 49 is provided on the outer surface of the limiting rod 41. A nut 48 is threaded on the outer surface of the threaded part 49. A drive wheel 37 is fixedly sleeved on the outer surface of the rotating shaft 32. A driven wheel 42 is fixedly sleeved on the outer surface of the limiting rod 41. A belt 43 is connected between the drive wheel 37 and the driven wheel 42.
[0022] By adopting the above technical solution, when the rotating shaft 32 rotates, it drives the driving wheel 37 to rotate. The driving wheel 37 and the driven wheel 42 are connected by a belt 43, which in turn causes the edge-collecting roller 46 to rotate, which facilitates the collection of the cut waste edges and prevents the waste edges from falling messily on the base plate 1. By rotating the nut 48, it is dislodged from the outer surface of the threaded part 49, and the edge-collecting roller 46 is removed, so that the collected waste edges can be centrally processed. The inserted rod 45 is inserted into the slot 47, so that when the waste edges are rolled up, the limiting rod 41 rotates, which can drive the edge-collecting roller 46 to rotate.
[0023] A first ear plate 13 is fixedly provided on the top surface of the base plate 1, and a first conveying roller 14 is rotatably connected inside the first ear plate 13. A second ear plate 15 is fixedly provided on the bottom surface of the fixed frame 2, and a second conveying roller 16 is rotatably connected inside the second ear plate 15. An unwinding roller 11 is fixedly provided on the top surface of the base plate 1, and a fixed plate 122 is fixedly provided on the top surface of the base plate 1. A first motor 121 is installed on one side of the fixed plate 122, and a winding roller 12 is rotatably provided between the fixed plates 122. The output end of the first motor 121 is fixedly connected to the winding roller 12 (the rotation torque of the first motor 121 and the third motor 31 is the same).
[0024] By adopting the above technical solution, the rust-proof paper can be supported and limited between the first conveying roller 14 and the second conveying roller 16. By turning on the first motor 121, the winding roller 12 is rotated to wind up the rust-proof paper after the edges are cut.
[0025] Working principle: First, the rust-proof paper to be cut is wound onto the surface of the unwinding roller 11, and then passed between the first conveying roller 14 and the second conveying roller 16. By turning on the second motor 21, the rotating rod 22 is rotated, causing one end of the guide rod 26 to rotate in the first fixed ear 23 and the other end to rotate in the second fixed ear 25. Then, the moving plate 24 and the vertical plate 3 can slide in the fixed frame 2, so that the two cutters 34 can move relative to each other. At this time, the first roller 33 and the second roller 36 are close to the edge cutting position of the rust-proof paper, and the two cutters 34 are located at the edge cutting position of the rust-proof paper. This makes it easy to adjust according to the different widths of rust-proof paper, so that the cutter 34 can be aligned with the edge cutting position of the rust-proof paper, avoiding product waste.
[0026] By turning on the first motor 121, the take-up roller 12 is rotated to take up the rust-proof paper after the edge is cut. At the same time, the third motor 31 is turned on, which causes the rotating shaft 32 to drive the first roller 33 to rotate and the cutter 34 to rotate to cut the edge of the rust-proof paper.
[0027] After cutting a certain distance, the first motor 121 and the third motor 31 are stopped. The workers wind the cut waste edges onto the take-up roller 46, and then turn the first motor 121 and the third motor 31 back on. When the rotating shaft 32 rotates, it drives the drive wheel 37 to rotate. The drive wheel 37 and the driven wheel 42 are connected by a belt 43, which in turn causes the take-up roller 46 to rotate, making it easier to collect the cut waste edges and prevent them from falling messily onto the base plate 1. After the cutting is completed, the nut 48 is turned to dislodge it from the outer surface of the threaded part 49, and the take-up roller 46 is removed, so that the collected waste edges can be centrally processed.
[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
