Description

Technical Field

[0001] This utility model relates to the field of strip steel conveying technology, specifically to a strip steel color-coated anti-slip device. Background Technology

[0002] In the metal processing industry, strip steel color coating is a key process for enhancing the added value of strip steel products and expanding application scenarios, and it is widely used in industries such as construction, home appliances, and automobiles. A strip steel color coating production line requires continuous operation through multiple stages, including uncoiling, cleaning, pretreatment, coating, baking, cooling, and recoiling. Stable conveying of the strip steel is a core prerequisite for ensuring coating quality and production efficiency.

[0003] However, slippage during the conveying process of strip steel for color coating can have a series of serious impacts on production. Strip position deviation is one of the most direct consequences of slippage. Because color coating production lines have extremely high precision requirements for the strip steel's trajectory, typically within ±2mm, once slippage occurs, the strip steel's position on the conveyor rollers or guide rollers will deviate from the preset path. This causes the strip steel edge to rub and collide with components such as the equipment side guide plates and coating rollers, potentially damaging the equipment and causing wrinkles and deformation at the strip steel edge. This directly affects the coating uniformity of subsequent coating processes—the edge coating thickness deviation may exceed 5μm, far exceeding industry standard requirements.

[0004] Surface scratches are another major threat to the quality of color-coated strip steel due to slippage. During slippage, relative sliding friction occurs between the strip steel and the conveyor rollers. If there are tiny impurities on the roller surface (such as iron filings or coating particles), scratches of varying depths will form on the strip steel surface. For color-coated products, surface scratches will damage the integrity of the coating, leading to a decrease in local corrosion resistance, and in severe cases, even requiring the entire roll to be downgraded or scrapped.

[0005] Decreased processing accuracy is a chain reaction triggered by slippage. In the coating process, the coating roller and the strip must maintain strict speed matching, with the speed difference controlled within ±0.5%. If the strip slips, its actual running speed will not be synchronized with the coating roller's rotation speed, leading to problems such as streaks, exposed substrate, and uneven coating thickness. For example, in roller coating, speed mismatch may cause wet film thickness deviations exceeding 10%. In the baking process, slippage causing strip stagnation or speed fluctuations can result in localized over-baking (coating yellowing and embrittlement) or under-baking (decreased coating adhesion), further reducing product yield.

[0006] More seriously, slippage can cause production line shutdowns. When strip slippage is severe, the strip may pile up or become entangled on the conveyor rollers, requiring an emergency shutdown. For continuous color coating lines, shutdowns not only lead to production interruptions (a single shutdown typically lasts 30 minutes to 2 hours), but also cause overheating and deformation due to prolonged exposure of the strip in the furnace, potentially leading to fires and other safety hazards.

Detailed Implementation

[0034] 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.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] Example 1

[0037] In order to reduce the probability of slippage during strip conveying and further reduce quality problems caused by slippage, this embodiment provides a device to prevent slippage during strip conveying.

[0038] like Figure 1 As shown, the device includes idler rollers 2 and pressure rollers 3. Multiple idler rollers 2 are distributed along the length of the support beam 1, and the ends of the idler rollers 2 are connected to the support beam 1 via bearing seats. The support beam 1 is connected to existing equipment or equipped with a corresponding frame on the strip conveying path, allowing the strip to be supported and conveyed via the idler rollers 2. The number of pressure rollers 3 is less than the number of idler rollers 2, as multiple pressure rollers 3 are discontinuously arranged directly above multiple idler rollers 2. Furthermore, an adjustment mechanism 5 is provided at the end of each pressure roller 3. The bottom of the adjustment mechanism 5 is connected to the support beam 1, and the height of the pressure roller 3 is adjusted by changing the state of the adjustment mechanism 5. This allows the pressure rollers 3 to apply pressure to the strip, thereby increasing the interaction force between the pressure rollers 3 and idler rollers 2 and the strip. With a constant coefficient of friction, this increases the resistance of the strip to movement relative to the pressure rollers 3 and idler rollers 2, reducing the probability of slippage during strip conveying.

[0039] The aforementioned idler roller 2 can be fitted with a sprocket as needed, and the sprocket is connected to the motor via a chain. It can also control the rotation of the idler roller 2 while the motor is running, thereby realizing the conveying and processing of strip steel.

[0040] In addition to adjusting the force between the pressure roller 3, the idler roller 2 and the strip, the coefficient of friction between the pressure roller 3, the idler roller 2 and the strip can be increased. For example, an anti-slip layer 23 can be set on the outer side wall of the pressure roller 3 and the idler roller 2. The anti-slip layer 23 is made of rubber material. Its high coefficient of friction can be used to increase the resistance between the strip and the roller body and reduce the chance of slippage during the conveying of the strip.

[0041] As is well known, the driving force for the movement of the strip is the friction between the roller and the strip. Therefore, during the process of the pressure roller 3 and the idler roller 2 driving the strip, the anti-slip layer 23 on their surfaces wears down. Currently, the existing anti-slip layer 23 is mostly bonded to the roller surface. When it wears down, either the entire roller needs to be replaced, or a considerable amount of time must be spent removing the original anti-slip layer 23 and then applying a new one. Replacing the roller means necessitating multiple spare rollers, increasing costs. Applying a new anti-slip layer 23 is time-consuming and impacts overall production.

[0042] like Figure 5 As shown, in order to solve the above problems quickly and at low cost, the anti-slip layer 23 can be made into a detachable structure. Specifically, both the idler roller 2 and the pressure roller 3 include a roller 21, an end piece 22 detachably installed at the end of the roller 21, and a replaceable anti-slip layer 23 fitted onto the roller 21. The end piece 22 is connected to the support beam 1 or the adjustment mechanism 5 through a bearing seat. When the end piece 22 is stably installed relative to the adjustment mechanism 5, the roller 21 and the end piece 22 can be disassembled first to release the restriction of the anti-slip layer 23. Then, the anti-slip layer 23 can be removed from one end of the roller 21, and a new anti-slip layer 23 can be fitted onto the roller 21. Then, the roller 21 can be installed between the two end pieces 22.

[0043] like Figure 6 , Figure 7 As shown, to achieve a detachable and stable connection between the anti-slip layer 23 and the roller 21, multiple snap-fit ​​grooves 211 are provided along the circumference of the outer wall of the roller 21. The snap-fit ​​grooves 211 are arranged along the length of the roller 21, and at least one end of the snap-fit ​​groove 211 is open. The anti-slip layer 23 is made of rubber material into a tubular structure. The length of the anti-slip layer 23 is less than or equal to the length of the roller 21, and multiple snap-fit ​​posts 231 are fixedly provided on the inner wall of the anti-slip layer 23. The snap-fit ​​posts 231 are installed in the snap-fit ​​grooves 211. Therefore, with the cooperation of the snap-fit ​​grooves 211 and the snap-fit ​​posts 231, the anti-slip layer 23 is braked to rotate synchronously with the roller 21, providing support for the roller 21 to drive the strip steel to move.

[0044] To facilitate the disassembly of end pieces 22 and rollers 21, and to meet the requirements of strip conveying, the length of rollers 21 is greater than the width of the strip, and the length of rollers 21 is less than or equal to the distance between the two end pieces 22. Furthermore, the end piece 22 is designed as a frustum-shaped structure, with the larger end of the end piece 22 positioned close to the roller 21. The end piece 22 is also fitted with a locking groove 211 to prevent the anti-slip layer 23 from detaching from the roller 21. An end shaft is integrally formed at the end of the end piece 22 furthest from the roller 21. The end shaft passes through a bearing housing, and a sprocket is fitted onto the end shaft.

[0045] like Figure 6 , Figure 9 , Figure 10As shown, to control the synchronous rotation of the end piece 22 and the roller 21, the end piece 22 near the roller 21 is provided with a mounting groove 221, and multiple second slots 224 are provided on the arc-shaped sidewall of the mounting groove 221. Multiple first slots 212 are provided on the end of the inner sidewall of the roller 21, with the first slots 212 and second slots 224 facing each other, and their closest ends being open. A connecting mechanism 24 is adjusted and provided inside the mounting groove 221. The connecting mechanism 24 includes an annular plate 241, and multiple locking posts 242 are fixedly provided on the outer sidewall of the annular plate 241. The locking posts 242 are adapted to the dimensions of the slots. When it is necessary to disassemble the roller 21, the annular plate 241 is controlled to move away from the roller 21, thereby disengaging the locking posts 242 from the first slots 212, and then the roller 21 can be removed from between the two end pieces 22. When it is necessary to stabilize the connected roller 21 and end piece 22, control the annular plate 241 to move in the opposite direction so that the two ends of the locking post 242 extend into the first locking groove 212 and the second locking groove 224 respectively, thereby controlling the roller 21 and end piece 22 to rotate synchronously.

[0046] like Figure 9 , Figure 10 As shown, in order to control the movement of the annular plate 241, a cross is fixedly installed on the inner side of the annular plate 241, and a plug rod 243 and a threaded rod 244 are fixedly installed on the same side of the cross and connected by a bearing. A slot 222 and a threaded hole 223 are provided on the end face of the mounting groove 221. The threaded rod 244 is inserted into the threaded hole 223, and the plug rod 243 is inserted into the slot 222. With the cooperation of the threaded rod 244, the plug rod 243, the threaded hole 223 and the slot 222, the annular plate 241 is stably installed relative to the end piece 22, and the movement of the annular plate 241 can be controlled by rotating the threaded rod 244.

[0047] like Figure 9 As shown, in order to rotate the threaded rod 244, the threaded rod 244 and the threaded hole 223 are located at the center of the mounting groove 221, and a countersunk hole is provided at the end shaft. The size of the countersunk hole is larger than the size of the threaded hole 223. At the same time, the countersunk hole communicates with the threaded hole 223. This arrangement makes it easy for the operator to hold a wrench and insert it into the countersunk hole, and insert the end of the polygonal wrench into the polygonal groove at the end of the threaded rod 244 to control the rotation of the threaded rod 244 and realize the adjustment of the position of the annular plate 241.

[0048] like Figure 2-4As shown, to adjust the height of the pressure roller 3, the adjusting mechanism 5 includes a vertical frame 51, a lifting beam 52 slidably sleeved on the vertical frame 51, and a bearing seat 53 installed below the lifting beam 52. The vertical frame 51 includes a horizontal plate 512 and two vertical rods 511. The bottom of the vertical rods 511 is connected to the support beam 1, and the top of the vertical rods 511 is bolted into the sleeve hole 513 of the horizontal plate 512. A threaded post 522 is fixedly installed in the middle of the lifting beam 52. The threaded post 522 passes through the through hole 514 of the horizontal plate 512, and two locking nuts 523 sleeved on the threaded post 522 are distributed on the upper and lower sides of the lifting beam 52. Under the action of the locking nuts 523, the lifting beam 52 can be stably controlled at a certain height, and the position of the lifting beam 52 can be adjusted as needed, thereby adjusting the height of the pressure roller 3. In addition, the vertical rods 511 pass through the through hole 521 at the end of the lifting beam 52, which can control the lifting beam 52 to be stably and movable.

[0049] Example 2

[0050] like Figure 1 As shown, based on embodiment 1, a tension roller 4 can also be provided between the two idler rollers 2. The tension roller 4 is located near the pressure roller 3, and the tension roller 4 is installed on the support beam 1 through the adjustment mechanism 5. By changing the state of the adjustment mechanism 5, the position of the tension roller 4 can be adjusted so that it presses down on the strip steel to increase its tension.

[0051] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0052] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
