Description
Technical Field
[0001] This utility model belongs to the field of steel strip processing technology, and in particular relates to a cutting device for steel strip processing with precise positioning. Background Technology
[0002] Steel strip is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors in producing various metal or mechanical products. In the process of processing steel strip, it is usually necessary to transport the steel strip to the cutting mechanism through a conveying device, and then the cutting mechanism cuts it into steel strips of the corresponding width. The processed steel strip can be used as a traction and carrying component of a belt conveyor, or it can be used to bundle goods.
[0003] During the processing of steel strip, the connection between the steel strip to be processed and the drive roller is not tight, causing the drive roller to slip during rotation. At the same time, the feed speed of the steel strip changes, resulting in a deviation between the cut steel strip width and the preset width, which in turn leads to a decrease in cutting accuracy. In order to solve the above problems, there is an urgent need for a steel strip processing cutting device with precise positioning. Utility Model Content
[0004] The purpose of this invention is to provide a steel strip cutting device with precise positioning to solve the problem of reduced cutting accuracy caused by slippage of the active roller.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for steel strip processing with precise positioning, comprising a base, a support block fixedly installed on the top of the base, a cylindrical rod fixedly installed on the support block through an internal through hole, a conveying component on one side of the top of the base, a cutting component on the other side of the top of the base, and a limiting component inside the base; The conveying assembly includes a support, on one side of which a motor is fixedly mounted. A first rotating shaft is fixedly mounted on the output shaft of the motor. A drive roller is fixedly mounted on the outer surface of the first rotating shaft. A drive sprocket is fixedly mounted on the outer surface of one end of the first rotating shaft. A chain is meshed on the outer surface of the drive sprocket. A cam is fixedly mounted on the outer surface of the first rotating shaft. A second slider is slidably mounted on the support through an internal groove. A push rod is fixedly mounted on the top of the second slider. A first spring is mounted on the outer side of the push rod. A second rotating shaft is rotatably mounted on the second slider through an internal through hole. A driven roller is rotatably mounted on the outer surface of the second rotating shaft.
[0006] As a further description of the above technical solution: The first rotating shaft is rotatably connected to the support through a through hole inside the support, the push rod is slidably connected to the support through a through hole inside the support, and the top of the first spring is fixedly connected to the support.
[0007] As a further description of the above technical solution: The bottom of the first spring is fixedly connected to the second slider, the top of the push rod is in contact with the cam, the bottom of the support is fixedly connected to the base, and the second rotating shaft passes through the sliding groove provided on the side of the base and is slidably connected to the base.
[0008] As a further description of the above technical solution: The limiting component includes a bidirectional threaded rod, a knob is fixedly installed on one side of the bidirectional threaded rod, and a first slider is threadedly installed on the outer surface of the bidirectional threaded rod, with two first sliders located on both sides of the bidirectional threaded rod respectively.
[0009] As a further description of the above technical solution: A limit block is fixedly installed on the top of the first slider, the first slider is slidably connected to the base through a groove provided on the top of the base, and the bidirectional threaded rod is rotatably connected to the base through a through hole provided on the side of the base.
[0010] As a further description of the above technical solution: The cutting assembly includes a support base, on which a crankshaft is fixedly mounted through a through hole at the top. A driven sprocket is fixedly mounted at one end of the crankshaft, and a connecting rod is rotatably mounted on the outside of the crankshaft.
[0011] As a further description of the above technical solution: A mounting block is rotatably mounted on one end of the connecting rod. A cutting blade is fixedly mounted on one side of the mounting block, and an upper pressure block is fixedly mounted on the other side of the mounting block. A sliding rod is slidably mounted on the upper pressure block through an internal through hole. A lower pressure block is fixedly mounted on the bottom of the sliding rod, and a second spring is mounted on the outside of the sliding rod.
[0012] As a further description of the above technical solution: The bottom of the support base is fixedly connected to the base, the surface of the driven sprocket is meshed with the chain, and the driven sprocket and the driving sprocket have the same number of teeth.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by incorporating a conveying assembly, the design enables the motor to be started during steel strip processing. This drives the active roller and cam to rotate via the first rotating shaft, thereby conveying the steel strip forward. Simultaneously, the first spring drives the second slider and driven roller to move upward, causing the steel strip to press against the active roller. This prevents the active roller from slipping and affecting the feed speed, thus improving the processing accuracy of the steel strip. When the steel strip is conveyed to the cutting assembly, the notch of the active roller moves above the steel strip and separates from it, stopping the conveying of the steel strip. At the same time, the cam presses down on the push rod, causing the second slider and driven roller to press down, thus preventing the steel strip from pressing against the notch of the active roller, which would cause the steel strip to bend and affect the feed speed, further improving the cutting accuracy.
[0014] 2. In this utility model, by providing a cutting component inside, the design enables the motor to be started when processing the steel strip, thereby driving the first rotating shaft and the drive sprocket to rotate. This, in turn, drives the driven sprocket and the crankshaft to rotate via the chain, which in turn drives the mounting block to move downward via the connecting rod. At the same time, the mounting block drives the cutting blade and the lower pressing block to move downward, thereby pressing and flattening the steel strip with the lower pressing block. Meanwhile, the cutting blade continues to move downward to complete the cutting, avoiding a decrease in cutting accuracy due to the elasticity of the steel strip. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This utility model provides a technical solution: a cutting device for steel strip processing with precise positioning, including a base 4, a support block 1 fixedly installed on the top of the base 4, a cylindrical rod 2 fixedly installed on the support block 1 through an internal through hole, a conveying component 5 on one side of the top of the base 4, a cutting component 6 on the other side of the top of the base 4, and a limiting component 3 inside the base 4.
[0023] The conveying assembly 5 includes a support 51, on one side of which a motor 52 is fixedly mounted. A first rotating shaft 53 is fixedly mounted on the output shaft of the motor 52. A drive roller 55 is fixedly mounted on the outer surface of the first rotating shaft 53. A drive sprocket 57 is fixedly mounted on the outer surface of the first rotating shaft 53. A chain 58 is meshed on the outer surface of the drive sprocket 57. A cam 54 is fixedly mounted on the outer surface of the first rotating shaft 53. A second slider 510 is slidably mounted on the support 51 through an internal groove. A push rod 56 is fixedly mounted on the top of the second slider 510. A first spring 59 is mounted on the outer side of the push rod 56. A second rotating shaft 512 is rotatably mounted on the second slider 510 through an internal through hole. A driven roller 511 is rotatably mounted on the outer surface of the second rotating shaft 512.
[0024] In use, the motor 52 can be started, causing the first rotating shaft 53 to rotate, which in turn drives the drive roller 55 and the cam 54 to rotate, thereby driving the steel belt forward. At the same time, since the first spring 59 is in a contracted state, the second slider 510 drives the driven roller 511 to move upward under the action of the first spring 59, thereby causing the steel belt to press against the drive roller 55. This prevents slippage between the drive roller 55 and the steel belt through the squeezing between the drive roller 55 and the driven roller 511. When the steel belt moves to the predetermined position, the notch of the drive roller 55 moves above the steel belt and separates from it, thereby stopping the steel belt from being conveyed. At the same time, the cam 54 presses down on the push rod 56, thereby pressing down the second slider 510 and the driven roller 511, thereby preventing the steel belt from pressing against the drive roller 55 and deforming the steel belt.
[0025] like Figure 3 As shown, the limiting component 3 includes a bidirectional threaded rod 34, a knob 31 is fixedly installed on one side of the bidirectional threaded rod 34, a first slider 32 is threadedly installed on the outer surface of the bidirectional threaded rod 34, and there are two first sliders 32 located on both sides of the bidirectional threaded rod 34 respectively. A limiting block 33 is fixedly installed on the top of the first slider 32. The first slider 32 is slidably connected to the base 4 through a groove provided on the top of the base 4. The bidirectional threaded rod 34 is rotatably connected to the base 4 through a through hole provided on the side of the base 4. When in use, the knob 31 can be adjusted to rotate the bidirectional threaded rod 34, thereby driving the first slider 32 and the limiting block 33 to move, so that the inner side of the limiting block 33 contacts the two sides of the steel strip, thereby adjusting the position of the steel strip to be processed relative to the conveying route, thereby eliminating the bending and deviation of the steel strip and avoiding the deviation of the cut.
[0026] like Figure 5 As shown, the cutting assembly 6 includes a support base 62. A crankshaft 69 is fixedly mounted on the support base 62 through a through hole at its top. A driven sprocket 610 is fixedly mounted on one end of the crankshaft 69. A connecting rod 68 is rotatably mounted on the outside of the crankshaft 69. A mounting block 66 is rotatably mounted on one end of the connecting rod 68. A cutting blade 67 is fixedly mounted on one side of the mounting block 66. An upper pressure block 61 is fixedly mounted on the other side of the mounting block 66. A sliding rod 65 is slidably mounted on the upper pressure block 61 through an internal through hole. 5. A lower pressure block 63 is fixedly installed at the bottom. A second spring 64 is installed on the outside of the slide rod 65. The bottom of the support base 62 is fixedly connected to the base 4. The outer surface of the driven sprocket 610 is meshed with the chain 58, and the driven sprocket 610 and the driving sprocket 57 have the same number of teeth. The mounting block 66 is slidably connected to the support base 62 through the internal sliding groove. The slide rod 65 passes through the internal spiral of the second spring 64. The top of the second spring 64 is fixedly connected to the upper pressure block 61. The second spring 64 is fixedly connected to the lower pressure block 63. When in use, the motor 52 can be started, which drives the first rotating shaft 53 and the drive sprocket 57 to rotate. At the same time, the drive sprocket 57 drives the driven sprocket 610 to rotate through the chain 58, which in turn drives the crankshaft 69 to rotate through the driven sprocket 610. This causes the mounting block 66 to drive the upper pressure block 61 and the cutting blade 67 to move downward. The upper pressure block 61 then drives the lower pressure block 63 to move downward through the second spring 64 and press the steel strip. Meanwhile, the cutting blade 67 continues to move downward and completes the cutting.
[0027] Working principle: When processing steel strip, the motor 52 can be started, which drives the drive roller 55 and cam 54 to rotate through the first rotating shaft 53, thereby driving the steel strip forward. The adjustable knob 31 can rotate its bidirectional threaded rod 34, which drives the first slider 32 and the limiting block 33 to move, so that the inner side of the limiting block 33 contacts the two sides of the steel strip, thereby adjusting the position of the steel strip to be processed relative to the conveying route. At the same time, since the first spring 59 is in a contracted state, the first spring 59 drives the driven roller 511 to move upward through the second slider 510, thereby making the steel strip press against the drive roller 55, thus preventing the steel strip from being squeezed between the drive roller 55 and the driven roller 511. When the drive roller 55 slips, the motor 52 drives the drive sprocket 57 to rotate via the first rotating shaft 53, which in turn drives the driven sprocket 610 and crankshaft 69 to rotate via the chain 58. This, in turn, drives the lower pressure block 63 and the cutting blade 67 to move downward via the connecting rod 68. As the lower pressure block 63 moves downward and presses the steel belt, the drive roller 55 moves above the steel belt at the notch and separates from it, thus stopping the steel belt from conveying. At the same time, the first rotating shaft 53 drives the cam 54 to press the push rod 56 downward, which in turn causes the second slider 510 and the driven roller 511 to press down, thus preventing the steel belt from sticking upward to the notch of the drive roller 55. Meanwhile, the cutting blade 67 continues to move downward and completes the cutting.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
