Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip steel processing technology, and more specifically, to an anti-friction and noise reduction device for a strip steel slitting machine. Background Technology
[0002] A friction-reducing noise reduction device for strip slitting machines refers to an auxiliary device specifically designed for use in strip slitting machines. Its purpose is to reduce friction between the strip and equipment components (such as slitting roller baffles and conveyor rollers) during the slitting process, thereby reducing noise generation, improving processing quality, extending equipment lifespan, and increasing production efficiency. In existing slitting machines, a common problem during strip cutting is that the cut strip often shifts to either side. This is because the cut strip has a certain degree of flexibility and will bend. Therefore, when the strip is cut again, the force of the cutting causes high-frequency vibrations. These high-frequency vibrations are transmitted to the other end of the strip, causing contact and collision between strips or between the strip and the equipment, resulting in noise. This leads to unnecessary friction between the sides of the strip and the sides of the conveyor rollers. This friction often produces harsh noise, affecting the working environment and potentially damaging the hearing of operators with prolonged exposure. Furthermore, this friction can also damage the surface of the strip, affecting product quality. Utility Model Content

[0016] The beneficial effects of the embodiments disclosed herein are as follows:
[0017] 1. Compared with traditional noise reduction devices, this utility model utilizes a two-stage vibration reduction design through the cooperation of a spring resistance device and a rubber roller. This absorbs some of the vibration transmitted during the cutting of the strip. The rubber roller is made of soft material and will not scratch the surface of the strip like metal rollers. Its elasticity also allows it to better conform to the contour of the strip. The rubber roller can maintain good contact with the strip through elastic deformation, providing stable positioning and preventing excessive lateral deviation, thus ensuring slitting accuracy. It can also buffer the impact force of the strip running and reduce sharp noise. The spring resistance device plays a good role in shock absorption and vibration reduction. The vibration generated during the operation of the slitting machine is absorbed and released through its own compression and expansion, buffering the vibration. Through the two-stage shock absorption and vibration reduction structure, some of the vibration on the strip is absorbed, thereby reducing the vibration frequency of the strip itself and thus reducing noise. This not only protects the equipment and improves reliability and stability, but also makes the strip run more smoothly, reduces slitting errors, improves slitting quality and accuracy, and makes the product more in line with production requirements.
[0018] 2. Compared with traditional devices, this utility model facilitates the replacement of slitting rollers through the cooperation of positioning blocks, springs, mounting plates, and fixing grooves, effectively reducing downtime and production costs. When slitting rollers are worn or damaged, operators can quickly replace them, avoiding production line shutdowns due to equipment failure and maintaining continuous production line operation, thus significantly improving overall production efficiency. In addition, this easy-to-replace design enhances the flexibility of the production line, enabling it to more efficiently meet the processing needs of strip steel of different specifications and materials. By quickly adjusting the slitting rollers, companies can optimize production processes and reduce unnecessary production steps. At the same time, this design reduces the difficulty and complexity of slitting roller maintenance, reduces additional maintenance costs, and timely replacement of worn parts can also prevent greater losses caused by equipment failure.

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0029] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0030] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Therefore, they should not be construed as limitations on this disclosure.
[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0034] like Figures 1-7 As shown, an anti-friction noise reduction device for a strip steel slitting machine according to an embodiment of the present disclosure is illustrated. It includes a support platform 1, a limiting component 2 fixedly mounted on the top of the support platform 1, the limiting component 2 including a fixed bracket 201 fixedly mounted on the top of the support platform 1, a movable plate 202 movably mounted inside the fixed bracket 201, a fixed seat 203 fixedly mounted on the top of the movable plate 202, a limiting groove 206 formed inside the fixed seat 203, a first fixed plate 205 movably mounted inside the limiting groove 206, a second hinge block 209 fixedly mounted at the bottom of the first fixed plate 205, a spring resistance 207 fixedly mounted inside the limiting groove 206, a first hinge block 208 movably mounted on the outer surface of the spring resistance 207, a connecting rod 210 hinged between the first hinge block 208 and the second hinge block 209, rubber rollers 204 movably mounted inside the two first fixed plates 205, and a slider 211 fixedly mounted on the outer side of the first fixed plates 205.
[0035] The operator conveys the strip steel cut by the slitting machine through the slitting roller 301, and then passes the cut strip steel through two rubber rollers 204. The rubber rollers 204 compress the strip steel due to the vibration of the strip steel during the movement of the slitting machine. The strip steel then compresses the first fixed plate 205 through the rubber rollers 204, which in turn compresses the second hinge block 209 through the first fixed plate 205, which in turn compresses the first hinge block 208 and the connecting rod 210 through the second hinge block 209. Finally, the slider 211 moves up and down inside the limiting groove 206, causing the first hinge block 208 to move on the outer surface of the spring resistance device 207, thereby reducing the swaying of the strip steel during the conveying process.
[0036] After being cut by the slitting machine, the strip steel is conveyed by the slitting roller 301 and passes through two components, the rubber rollers 204. During the movement of the strip steel, the vibration of the slitting machine causes the strip steel to squeeze the rubber rollers 204, which in turn squeezes the first fixed plate 205. The first fixed plate 205 then squeezes the second hinge block 209, which in turn squeezes the first hinge block 208 and the connecting rod 210. At the same time, the slider 211 moves up and down inside the limiting groove 206, causing the first hinge block 208 to move on the outer surface of the spring resistance device 207. This effectively buffers and stabilizes the strip steel, reducing its shaking during conveying and ensuring smooth subsequent processing. Compared with traditional noise reduction devices, this noise reduction device uses the spring resistance device 207 and the rubber rollers 204. The combination of these components reduces strip vibration during transmission. The 204 rubber roller, being soft and unlike metal rollers, won't scratch the strip surface. Its elasticity allows it to better conform to the strip's contour. If the strip experiences slight fluctuations or deviations during operation, the rubber roller's elastic deformation ensures consistent contact with the strip, providing stable positioning and preventing excessive lateral displacement, thus guaranteeing slitting accuracy. It also buffers the impact of strip movement, reducing sharp noise. Meanwhile, the 207 spring resistance effectively dampens vibrations, absorbing and releasing energy through compression and extension of the roller, thus buffering the vibrations. This protects the equipment, reduces component wear and loosening, and lowers the failure rate, improving reliability and stability. It also ensures smoother strip movement, reducing slitting errors, improving slitting quality and accuracy, and making the product better meet production requirements.
[0037] In some examples, the support platform 1 is movably mounted with an installation component 3, which includes a guide groove 308 formed inside the support platform 1. An installation plate 304 is movably mounted inside the guide groove 308. A support plate 302 is fixedly mounted on the top of the installation plate 304. A slitting roller 301 is movably mounted between the two support plates 302.
[0038] The bottom of the mounting plate 304 is provided with a fixing groove 309. The bottom of the support platform 1 is fixedly installed with a box 310. The inside of the fixing groove 309 is fixedly installed with a positioning block 303. The bottom of the positioning block 303 is fixedly installed with a pull rod 305, and one end of the pull rod 305 passes through the inside of the box 310. A spring 306 is fixedly installed between the positioning block 303 and the box 310. A push rod 307 is fixedly installed on the left side of the mounting plate 304.
[0039] Workers need to replace the slitting roller 301 according to different strip sizes. By holding the pull rod 305, the positioning block 303 is slowly moved downwards. The positioning block 303 compresses the spring 306 inside the housing 310, causing the positioning block 303 to disengage from the fixing groove 309 and enter the housing 310. Now the positioning block 303 is released from its restriction on the mounting plate 304. Next, by holding the push rod 307, the mounting plate 304, slitting roller 301, and support plate 304 are moved together. 02. Slowly move the slitting roller 301 out of the support platform 1. Now, a suitable slitting roller 301 needs to be installed inside the support platform 1. Hold the push rod 307 and push the mounting plate 304 into the guide groove 308 through the push rod 307. The mounting plate 304 drives the slitting roller 301 and the support plate 302 to move synchronously. When the mounting plate 304 is completely inside the guide groove 308, release the pull rod 305. At this time, the positioning block 303 squeezes the spring 306 and quickly enters the fixing groove 309, thus completing the replacement of the slitting roller 301.
[0040] During the operation of the strip slitting machine, the slitting roller 301 needs to be replaced to accommodate different strip sizes. The operator first holds the pull rod 305, using it to slowly lower the sliding block positioning block 303. During this process, the positioning block 303 compresses the spring 306 within the housing 310 until it disengages from the fixing groove 309 and enters the housing 310, releasing the restriction on the mounting plate 304. Then, the operator holds the handle push rod 307, slowly moving the locking block mounting plate 304, along with the slitting roller 301 and its support plate 302, out of the support platform 1. Next, a slitting roller 301 of the appropriate size is prepared. The operator again holds the push rod 307 and pushes the mounting plate 304 into the guide groove 308. The mounting plate 304 drives the slitting roller 301 and support plate 302 to move synchronously. When the mounting plate 304 is fully in place, the pull rod 305 is released, and the sliding block positioning block 303 quickly engages with the fixing groove 309 under the action of the spring 306. The replacement of the slitting roller 301 was successfully completed. Compared with traditional devices, this device facilitates the replacement of the slitting roller 301 through the cooperation between the positioning block 303, spring 306, mounting plate 304, and fixing groove 309, effectively reducing downtime and production costs. When the slitting roller 301 is worn or damaged, operators can quickly replace it, avoiding production line shutdowns due to equipment failure and maintaining continuous production line operation, thus significantly improving overall production efficiency. In addition, this easy-to-replace design enhances the flexibility of the production line, enabling it to more efficiently meet the processing needs of strip steel of different specifications and materials. By quickly adjusting the slitting roller 301, enterprises can optimize production processes and reduce unnecessary production steps. At the same time, this design reduces the difficulty and complexity of slitting roller maintenance, reduces additional maintenance costs, and timely replacement of worn parts can also avoid greater losses caused by equipment failure.
[0041] In some examples, a second fixing plate 4 is fixedly installed at the bottom of the support platform 1, and a connecting plate 6 is fixedly installed between the two second fixing plates 4.
[0042] Since a connecting plate 6 is fixedly installed between the two second fixing plates 4, the cooperation between the second fixing plates 4 and the connecting plate 6 facilitates stable support for the support platform 1, ensuring the stability of the support platform 1 during use and improving the utilization efficiency of the support platform 1.
[0043] In some examples, the support platform 1 has a positioning groove 9 inside, a fixing block 10 is movably installed inside the positioning groove 9, and a toolbox 11 is fixedly installed on the back of the fixing block 10.
[0044] By holding the toolbox 11, the fixing block 10 is slowly placed into the positioning groove 9. The positioning groove 9 limits and fixes the fixing block 10. By adding the toolbox 11, it is convenient for the staff to take out and place maintenance tools inside the toolbox 11.
[0045] In some examples, the first hinge block 208 and the connecting rod 210 are paired up, with two sets moving on the outer surface of the spring resistance 207.
[0046] Since the first hinge block 208 and the connecting rod 210 are in pairs, there are two sets of movable parts on the outer surface of the spring resistance device 207. Through the cooperation between the first hinge block 208 and the connecting rod 210, the slider 211 and the first fixed plate 205 can move up and down in the limiting groove 206 to dampen the strip steel and ensure the stability of the strip steel during use.
[0047] In some examples, a vertical plate 7 is fixedly installed on the top of the support platform 1, and a rotating shaft 8 is movably installed between the two vertical plates 7.
[0048] Since a rotating shaft 8 is movably installed between the two vertical plates 7, the strip steel can be easily moved on the outer surface of the rotating shaft 8 through the cooperation between the vertical plates 7 and the rotating shaft 8, thus ensuring the stability of the strip steel during use.
[0049] In some examples, a reinforcing rib 5 is fixedly installed at the angle between the second fixing plate 4 and the connecting plate 6, and the reinforcing rib 5 is triangular in shape.
[0050] Since the reinforcing rib 5 is triangular in shape at the angle between the second fixing plate 4 and the connecting plate 6, and triangles have the characteristic of stability, the stability of the second fixing plate 4 and the connecting plate 6 is guaranteed during use, and the efficiency of the second fixing plate 4 and the connecting plate 6 is improved.
[0051] In some examples, a first positioning block 12 is fixedly installed on the left side of the rubber roller 204, and a second positioning block 14 is fixedly installed on the left side of the fixed bracket 201. A limiting workpiece 13 is fixedly installed on the outer surface of the second positioning block 14, and one end of the limiting workpiece 13 is engaged with the outer surface of the first positioning block 12.
[0052] The fixing seat 203 is replaced according to the width of the strip. By holding the limiting workpiece 13, the limiting workpiece 13 is rotated on the outer surface of the second positioning block 14, so that one end of the limiting workpiece 13 is engaged with the first positioning block 12 and slowly removed. Then, by holding the first positioning block 12, the movable plate 202 is slowly removed from the inside of the fixing bracket 201. The movable plate 202 drives the fixing seat 203 to move synchronously, thus completing the removal of the fixing seat 203 from the inside of the fixing bracket 201. Then, the appropriate fixing seat 203 and the movable plate 202 are pushed into the inside of the fixing bracket 201. The limiting workpiece 13 is rotated on the outer surface of the second positioning block 14 until one end of the limiting workpiece 13 is engaged with the inside of the first positioning block 12, thereby completing the replacement of the fixing seat 203.
[0053] In some examples, the inner diameter of the positioning groove 9 is equal to the outer diameter of the fixing block 10, and the interior of the fixing block 10 has a smooth surface design.
[0054] Since the inner diameter of the positioning groove 9 is equal to the outer diameter of the fixing block 10, and the inside of the fixing block 10 has a smooth surface design, it is easy for the working hand to hold the toolbox 11 and slowly position the fixing block 10 into the inside of the positioning groove 9, thus ensuring the installation efficiency of the toolbox 11.
[0055] In some examples, the height of the slitting roller 301 is the same as the height of the fixed support 201, and the blades of the slitting roller 301 are arranged in a linear array.
[0056] Since the height of the slitting roller 301 is the same as the height of the fixed support 201, and the blades of the slitting roller 301 are arranged in a linear array, this facilitates uniform cutting of the strip steel and improves the efficiency of the strip steel cutting process.
[0057] Working principle and usage process of this utility model:
[0058] The operator conveys the strip steel cut by the slitting machine through the slitting roller 301, and then passes the cut strip steel through two rubber rollers 204. The rubber rollers 204 compress the strip steel due to the vibration of the strip steel during the movement of the slitting machine. The strip steel then compresses the first fixed plate 205 through the rubber rollers 204, which in turn compresses the second hinge block 209 through the first fixed plate 205, which in turn compresses the first hinge block 208 and the connecting rod 210 through the second hinge block 209. Finally, the slider 211 moves up and down inside the limiting groove 206, causing the first hinge block 208 to move on the outer surface of the spring resistance device 207, thereby reducing the swaying of the strip steel during the conveying process.
[0059] Workers need to replace the slitting roller 301 according to different strip sizes. By holding the pull rod 305, the positioning block 303 is slowly moved downwards. The positioning block 303 compresses the spring 306 inside the housing 310, causing the positioning block 303 to disengage from the fixing groove 309 and enter the housing 310. Now the positioning block 303 is released from its restriction on the mounting plate 304. Next, by holding the push rod 307, the mounting plate 304, slitting roller 301, and support plate 304 are moved together. 02. Slowly move the slitting roller 301 out of the support platform 1. Now, a suitable slitting roller 301 needs to be installed inside the support platform 1. Hold the push rod 307 and push the mounting plate 304 into the guide groove 308 through the push rod 307. The mounting plate 304 drives the slitting roller 301 and the support plate 302 to move synchronously. When the mounting plate 304 is completely inside the guide groove 308, release the pull rod 305. At this time, the positioning block 303 squeezes the spring 306 and quickly enters the fixing groove 309, thus completing the replacement of the slitting roller 301.
