Detailed Implementation

[0017] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0018] It should be noted that during the conveying of bar stock using water-cooled roller conveyors, a significant amount of iron powder is easily generated at the conveying site. This can cause the rollers in the roller conveyor system to jam during rotation. If the rollers of the water-cooled roller conveyor become stuck, it can not only damage the corresponding drive motor but also slow down the conveying speed of the bar stock, and even lead to steel stamping accidents, which is detrimental to the safe operation of production. In related technologies, cleaning of the water-cooled roller conveyor is mostly carried out by operators during maintenance periods. However, because the bar stock conveyed by the water-cooled roller conveyor is at a high temperature, operators are usually performing cleaning work in a high-temperature environment, which increases the risk of injury to the operators.

[0019] In view of this, such as Figure 1 and Figure 2 As shown, a first aspect of the present disclosure provides a roller device, comprising: a support assembly 100 having a support wall 101; a roller assembly 200 having a bearing wall 201 for rolling cooperation with a material to be conveyed; a drive assembly 300 connected to the roller assembly 200 for driving the roller assembly 200 to rotate the bearing wall 201; a scraper assembly 400 having a scraping side for slidably abutting against the support wall 101; and a transmission assembly 500 transmissionally connected between the bearing wall 201 and the scraper assembly 400 for driving the scraper assembly 400 to move so that the scraping side slides along the support wall 101.

[0020] The idler roller device provided in this embodiment includes the aforementioned support assembly 100, idler roller assembly 200, drive assembly 300, scraper assembly 400, and transmission assembly 500. The support wall 101 of the support assembly 100 can support the idler roller assembly 200, thereby improving the installation stability of the idler roller assembly 200 and facilitating stable material conveying operations. The bearing wall 201 of the idler roller assembly 200 can roll in conjunction with the material to be conveyed to drive its displacement, thus achieving material conveying. The drive assembly 300 is connected to the idler roller assembly 200 and drives it. When the drive assembly 300 is running, the idler roller assembly 200... The support wall 201 can rotate, allowing the idler roller assembly 200 to drive the material to be conveyed to move using the friction between the support wall 201 and the material to be conveyed. The scraping side of the scraper assembly 400 can slide in contact with the aforementioned support wall 101. The transmission assembly 500 is connected between the support wall 201 and the scraper assembly 400 and is used to drive the scraper assembly 400 to move, so that the scraping side slides along the support wall 101. Thus, during the rotation of the support wall 201, the scraper assembly 400 can slide on the aforementioned support wall 101. 1. The method of wiping away dirt on the support wall 101 reduces the possibility of a large amount of dirt accumulating on the support wall 101, thereby reducing the amount of dirt in the vicinity of the idler assembly 200. This reduces the risk of the idler assembly 200 getting stuck or jammed due to the aforementioned dirt, which helps to ensure the material conveying speed of the idler device and reduces the possibility of material accumulation and impact during conveying, thus improving the safety and stability of material conveying operations. Furthermore, based on the aforementioned configuration, both the idler assembly 200 and the scraper assembly 400 can be driven by the drive assembly 300, without... An independent drive device needs to be configured for the scraper assembly 400, which is beneficial to improve the structural compactness of the idler roller device. The scraper assembly 400 can operate synchronously with the idler roller assembly 200. During the material conveying process of the idler roller assembly 200, the scraper assembly 400 can clean the aforementioned support wall 101 accordingly, which can improve the timeliness of the support wall 101 cleaning operation, reduce the probability of dirt accumulating and scaling on the support wall 101, help reduce the sliding resistance on the scraping side, and ensure the cleaning efficiency and cleaning effect of the scraper assembly 400 on the support wall 101.

[0021] It should be noted that the aforementioned idler roller device proposed in this disclosure can be used as a component of a roller conveyor system in practical applications. The aforementioned roller conveyor system may include multiple aforementioned idler roller devices, which can be arranged according to a certain conveying path. When the drive assembly 300 of the multiple aforementioned idler roller devices is running, the idler roller assembly 200 on which the material to be conveyed is placed on the bearing wall 201 can use the rolling cooperation relationship between its bearing wall 201 and the material to be conveyed to transfer the material to be conveyed to the adjacent idler roller assembly 200 on the conveying path, so that the material to be conveyed can move according to the aforementioned conveying path and realize the conveying of the material.

[0022] Taking the aforementioned idler roller assembly 200 as a component of a roller conveyor system for conveying bar stock as an example, the material to be conveyed can be high-temperature bar stock, and the conveying path can pass through the tapping zone and the water process zone. That is, the aforementioned roller conveyor system can be a water-cooled roller conveyor system. Accordingly, the aforementioned roller conveyor system can load high-temperature bar stock at the tapping zone and drive the high-temperature bar stock through the water process zone so that the high-temperature bar stock can be treated by water during the conveying process. In this case, the aforementioned contaminants can be, but are not limited to, iron powder generated during the bar stock conveying process. Based on the aforementioned configuration of the idler roller device, during the bar stock conveying process, the scraper assembly 400 can operate synchronously with the idler roller assembly 200 to support the aforementioned... The iron powder on the support wall 101 is wiped off, thereby reducing the amount of iron powder on the support wall 101 and preventing a large amount of iron powder from accumulating near the idler assembly 200. This reduces the impact of iron powder on the operation of the idler assembly 200, lowers the risk of the idler assembly 200 jamming or seizing, ensures the safe and stable conveying of the bar stock, reduces the risk of steel impact accidents during bar stock conveying, and improves the timeliness of the support wall 101 cleaning operation. It also reduces the risk of iron powder on the support wall 101 located in the aforementioned water process area clumping or adhering to the support wall 101 under the influence of moisture. This helps to reduce the sliding resistance on the scraping side and ensures the cleaning efficiency and cleaning effect of the scraper assembly 400 on the support wall 101.

[0023] It is understandable that, in practical applications, the aforementioned support wall 101 can be located below the aforementioned idler assembly 200 so that the bracket assembly 100 can provide structural support for the idler assembly 200. Correspondingly, since the bearing wall 201 is in a rotating state during the conveying process and the iron powder has a high density, the iron powder generated during the conveying process is easy to fall off from the bearing wall 201 onto the support wall 101. If the amount of iron powder accumulated on the support wall 101 is high, the iron powder is easy to come into contact with the rotating parts of the idler assembly 200, thereby affecting the operation of the idler assembly 200. Furthermore, when the aforementioned support wall 101 is located in the aforementioned water process area, the iron powder is also easy to agglomerate or adhere to the support wall 101, increasing the difficulty of cleaning during maintenance. Based on the aforementioned configuration, the idler roller device provided in this disclosure can clean the support wall 101 using the scraper assembly 400 during the conveying of the bar stock. This reduces the probability of a large amount of iron powder accumulating or adhering on the support wall 101 and the sliding resistance of the scraper assembly 400, which helps to ensure the cleaning efficiency and effect of the scraper assembly 400 on the support wall 101. Thus, while ensuring the smooth operation of the idler roller assembly 200, it reduces the cleaning workload of operators during maintenance, improves the safety of bar stock conveying operations, and enhances the adaptability of the idler roller device to water processes.

[0024] It is understandable that, such as Figure 1 and Figure 2 As shown, a gap is formed between the aforementioned support wall 101 and the aforementioned bearing wall 201, thereby avoiding structural interference between the support wall 101 and the bearing wall 201; correspondingly, the aforementioned scraper assembly 400 can be arranged between the aforementioned support wall 101 and the aforementioned bearing wall 201 to avoid the scraper assembly 400 affecting the space above the bearing wall 201, and to prevent the scraper assembly 400 from structurally interfering with the material to be conveyed.

[0025] It is understood that the aforementioned drive assembly 300 may include a drive motor, the aforementioned roller assembly 200 may include a roller body 230, the outer peripheral wall of the aforementioned roller body 230 is configured as the aforementioned bearing wall 201, the aforementioned drive motor is connected to the aforementioned roller body 230 and is used to drive the aforementioned roller body 230 to rotate, so that when the drive motor is running, the aforementioned bearing wall 201 can rotate, so that the bearing wall 201 can roll and cooperate with the material to be conveyed.

[0026] It is understandable that the aforementioned scraper assembly 400 can be made of high-temperature resistant and wear-resistant materials, which is beneficial to extending the service life of the scraper assembly 400.

[0027] like Figure 1 and Figure 2As shown, in some examples, the idler assembly 200 includes: a first idler support 210 disposed on the support wall 101; a second idler support 220 disposed on the support wall 101, the first idler support 210 and the second idler support 220 being arranged at intervals along a first direction, a scraper assembly 400 being arranged between the first idler support 210 and the second idler support 220; a roller body 230, the outer peripheral wall of the roller body 230 being configured as a bearing wall 201, the two ends of the roller body 230 being rotatably connected to the first idler support 210 and the second idler support 220 respectively in the axial direction, and a drive assembly 300 for driving the roller body 230 to rotate; wherein, the scraping side is adapted to slide relative to the support wall 101 along a second direction, the first direction being perpendicular to the second direction, and both the first direction and the second direction being parallel to the support wall 101.

[0028] In this technical solution, the idler assembly 200 may include the aforementioned first idler support 210, the aforementioned second idler support 220, and the aforementioned roller body 230. Based on the aforementioned configuration, the idler assembly 200 can be connected to the support assembly 100 through the aforementioned first idler support 210 and the aforementioned second idler support 220, and provide rotational support for the aforementioned roller body 230, which is beneficial to ensuring the rotational stability and conveying efficiency of the bearing wall 201. The sliding direction of the scraping side can be perpendicular to the axial direction of the roller body 230, and the scraper assembly 400 is located between the first idler support 210 and the second idler support 220, thereby preventing the scraper assembly 400 from pushing dirt onto the first idler support 210 or the second idler support 220, and preventing dirt from approaching the connection between the roller body 230 and the idler support, thereby further reducing the risk of the roller body 230 jamming or getting stuck, and providing a more reliable guarantee for the stable operation of the idler assembly 200.

[0029] It is understandable that by setting the axial direction of the roller body 230 to be parallel to the support wall 101, the installation stability of the roller assembly 200 on the bracket assembly 100 can be improved; by setting the sliding direction of the scraping side to be parallel to the support wall 101, it is easier for the scraping side to clean different positions on the support wall 101, and the stability of the contact force between the scraping side and the support wall 101 can be improved, which helps to prevent the scraper assembly 400 from getting stuck.

[0030] like Figure 1 and Figure 2 As shown, in some examples, the transmission assembly 500 includes: a first chain drive mechanism 510, including a first drive chain 511 drively connected to the support wall 201, the first drive chain 511 having a first chain segment 511a extending in a second direction, and a scraper assembly 400 disposed on the first drive chain 511; wherein, when the scraper assembly 400 is located on the first chain segment 511a, the scraping side abuts against the support wall 101.

[0031] In this technical solution, the transmission component 500 may include the aforementioned first chain drive mechanism 510. Based on the aforementioned configuration, the power of the aforementioned bearing wall 201 can be transmitted to the first transmission chain 511, so that the first transmission chain 511 drives the scraper assembly 400 to move. Correspondingly, when the scraper assembly 400 is located at the aforementioned first chain segment 511a, the first transmission chain 511 can drive the scraping side to slide along the aforementioned second direction on the support wall 101 to wipe away dirt on the support wall 101. Furthermore, the chain drive mechanism has high transmission stability and strong tolerance to harsh environments such as high temperature, oil, and dust. When the idler roller device is applied to the aforementioned water conveyor system, it can help the scraper assembly 400 to stably clean iron powder on the support surface, reduce the maintenance cost of the transmission component 500, and extend the service life of the transmission component 500.

[0032] It is understood that the aforementioned first transmission chain 511 can be composed of multiple chain links, which are connected end to end to form a closed loop structure. In practical applications, the aforementioned scraper assembly 400 can be fixedly connected to at least one of the aforementioned chain links. The first chain drive mechanism 510 may also include a first sprocket 512 and a second sprocket 513. The first transmission chain 511 can be wound around the first sprocket 512 and the second sprocket 513 to transmit power between the first sprocket 512 and the second sprocket 513. When the first transmission chain 511 is wound around the first sprocket 512 and the second sprocket 513, the first transmission chain 51... The extension direction of 1 can be relatively fixed. For example, if the first transmission chain 511 is divided into segments along the extension direction of the first transmission chain 511, the first transmission chain 511 can be divided into multiple chain segments. Correspondingly, at least one of the multiple chain segments is the first chain segment 511a. When the first transmission chain 511 is running, the chain link connected to the scraper assembly 400 can drive the scraper assembly 400 to periodically pass through the first chain segment 511a, thereby enabling the scraper assembly 400 to periodically wipe away dirt on the support wall 101 during the rotation of the bearing wall 201.

[0033] like Figure 1 and Figure 2 As shown, in some examples, the first chain drive mechanism 510 further includes: a first sprocket 512 and a second sprocket 513. The first sprocket 512 is drivenly connected to the support wall 201, and the second sprocket 513 is arranged at intervals from the first sprocket 512 along a second direction. The axial direction of the first sprocket 512 and the axial direction of the second sprocket 513 are both parallel to the first direction. A first drive chain 511 is drivenly connected between the first sprocket 512 and the second sprocket 513. The distance between the axis of the first sprocket 512 and the axis of the second sprocket 513 in the second direction is greater than or equal to the length of the support wall 101 in the second direction.

[0034] In this technical solution, the first chain drive mechanism 510 may further include the aforementioned first sprocket 512 and the aforementioned second sprocket 513. Based on the aforementioned configuration, under the constraint of the first sprocket 512 and the second sprocket 513, the first drive chain 511 may have a relatively fixed extension direction and may be divided into a first chain segment 511a, a second chain segment 511b, a third chain segment 511c, and a fourth chain segment 511d. The first chain segment 511a and the second chain segment 511b both extend along the aforementioned second direction and along a direction perpendicular to the support wall 101. The first chain segment 511a is located between the second chain segment 511b and the support wall 101. Between the support walls 101, that is, the first chain segment 511a is closer to the support wall 101 than the second chain segment 511b, so that the scraper assembly 400 can abut against the support wall 101 when it is located at the first chain segment 511a. The third chain segment 511c is connected between the first chain segment 511a and the second chain segment 511b, and the third chain segment 511c is arranged around the first sprocket 512. The fourth chain segment 511d is connected between the first chain segment 511a and the second chain segment 511b, and the fourth chain segment 511d is connected between the first chain segment 511a and the second chain segment 511b. Chain segment 511d is arranged around the second sprocket 513, and the aforementioned first sprocket 512 can serve as the driving wheel of the first chain drive mechanism 510 and receive power from the aforementioned bearing wall 201. Thus, when the bearing wall 201 rotates, the first sprocket 512 can drive the first drive chain 511 and the second sprocket 513 to rotate, so that the scraper assembly 400 can periodically pass through the aforementioned first chain segment 511a and cause the aforementioned scraping side to slide against the aforementioned support wall 101, thereby achieving the removal of dirt from the aforementioned support wall 101. By setting the distance between the axis of the first sprocket 512 and the axis of the second sprocket 513 in the second direction to be greater than or equal to the length of the support wall 101 in the second direction, the length of the first chain segment 511a can be correspondingly greater than or equal to the length of the support wall 101 in the second direction. This ensures the cleaning range of the scraper assembly 400 on the support wall 101, which helps to reduce the cleaning dead angles of the scraper assembly 400 and improve the cleaning effect of the scraper assembly 400 on the support wall 101.

[0035] like Figure 1 and Figure 2As shown, in some examples, the first chain drive mechanism 510 further includes: a first axle 514 and a second axle 515, a first sprocket 512 sleeved on the first axle 514, a second sprocket 513 sleeved on the second axle 515, and both the first axle 514 and the second axle 515 extending along a first direction; a first axle support 516 and a second axle support 517, disposed on the support wall 101, with the two ends of the first axle 514 rotatably connected to the first axle support 516 and the second axle support 517 respectively. A seat 517; a third shaft support and a fourth shaft support 519 are disposed on the support wall 101, and the two ends of the second wheel shaft 515 are rotatably connected to the third shaft support and the fourth shaft support 519 respectively in the axial direction; wherein, the minimum distance between the first shaft support 516 and the second shaft support 517 in the first direction and the minimum distance between the third shaft support and the fourth shaft support 519 in the first direction are both greater than or equal to the minimum distance between the first idler support 210 and the second idler support 220 in the first direction.

[0036] In this technical solution, the first chain drive mechanism 510 may further include the aforementioned first wheel axle 514, second wheel axle 515, first axle support 516, second axle support 517, third axle support and fourth axle support 519. Based on the aforementioned configuration, on the one hand, the first chain drive mechanism 510 can utilize the aforementioned shaft supports and axles to support the corresponding sprockets, thereby improving the structural stability and reliability of the first chain drive mechanism 510 and facilitating the stable operation of the first drive chain 511, the first sprocket 512, and the second sprocket 513. On the other hand, the spacing between the first shaft support 516 and the second shaft support 517 in the first direction, and the spacing between the third shaft support and the fourth shaft support 519 in the first direction, can all be relatively large, thus reserving a larger space for the movement of the scraper assembly 400. This allows for extending the length of the scraper assembly 400 in the first direction, further increasing the cleaning range of the scraper assembly 400 on the support wall 101, reducing the cleaning dead angles of the scraper assembly 400, and improving the cleaning effect of the scraper assembly 400 on the support wall 101.

[0037] For example, the scraper assembly 400 and the support wall 101 are centered along a first direction, and the length of the scraper assembly 400 in the first direction is greater than or equal to 0.5 times the length of the support wall 101 in the first direction.

[0038] like Figure 1 and Figure 2 As shown, in some examples, there are multiple first drive chains 511, multiple first sprockets 512 and multiple second sprockets 513. Multiple first sprockets 512 are arranged at intervals along a first direction, and multiple second sprockets 513 are arranged at intervals along a first direction. The first sprockets 512 and the second sprockets 513 are arranged in a one-to-one correspondence with the first drive chains 511. Multiple first drive chains 511 are all connected to the scraper assembly 400.

[0039] In this technical solution, the first chain drive mechanism 510 may have multiple parallel first drive chains 511, and each first drive chain 511 may be supported by a set of first sprockets 512 and second sprockets 513. The scraper assembly 400 may be connected to multiple of the aforementioned first drive chains 511 simultaneously. Based on this, the drive assembly 500 may be connected to the scraper assembly 400 at multiple points, and a certain span may be formed between the multiple connection points, which can reduce the overhang length of the scraper assembly 400, which is beneficial to improving the motion stability and installation stability of the scraper assembly 400, thereby enhancing the cleaning effect of the scraper assembly 400 on the support wall 101.

[0040] like Figure 1 and Figure 2 As shown, in some examples, the transmission assembly 500 further includes a second chain drive mechanism 520, which is drive-connected between the support wall 201 and the first chain drive mechanism 510.

[0041] In this technical solution, the transmission assembly 500 may further include the aforementioned second chain drive mechanism 520. Based on the aforementioned configuration, the first chain drive mechanism 510 can receive power from the aforementioned bearing wall 201 via chain drive. The chain drive mechanism has high transmission stability and strong tolerance to harsh environments such as high temperature, oil, and dust. When the idler roller device is applied to the aforementioned water conveyor system, it facilitates the stable power input of the first chain drive mechanism 510 through the second chain drive mechanism 520, making it easier for the scraper assembly 400 to stably clean iron powder from the support surface, reducing the maintenance cost of the transmission assembly 500, and extending the service life of the transmission assembly 500.

[0042] like Figure 1 and Figure 2 As shown, in some examples, the second chain drive mechanism 520 includes a second drive chain 521, and both the first drive chain 511 and the second drive chain 521 are aluminized chains or ceramic chains.

[0043] In this technical solution, the second chain drive mechanism 520 may include the aforementioned second drive chain 521, and both the first drive chain 511 and the second drive chain 521 are aluminized chains or ceramic chains. Based on the aforementioned configuration, the wear resistance and high-temperature resistance of the first drive chain 511 and the second drive chain 521 can be improved, enhancing the adaptability of the first chain drive mechanism 510 and the second chain drive mechanism 520 to harsh environments such as high temperature and dust.
