Description

Technical Field

[0001] This application belongs to the field of roller conveyor technology, specifically relating to a water-cooled roller fixture for strip conveying. Background Technology

[0002] In the strip rolling process of industrial production, the roller conveyor system plays a crucial role, responsible for smoothly and efficiently transporting the strip from the finishing mill exit to the coiling point. When the strip is transported by roller conveyor, the temperature of the strip from the finishing mill exit to the coiling point usually reaches a high temperature range of 600℃-650℃. Forced cooling is generally used to reduce the temperature of the strip and the rollers.

[0003] However, prolonged exposure to high temperatures gradually reduces the strength of the rollers, potentially leading to breakage. As temperature rises, different parts of the roller expand to varying degrees, resulting in inconsistent thermal expansion and component deformation. This causes dimensional deviations in the rollers, affecting production quality. Furthermore, during high-speed conveyor belt transport, cooling water inevitably splashes onto the couplings. This accelerates the oxidation and corrosion of the metal on the couplings, causing rust and a significant decrease in their mechanical properties. Ultimately, this can lead to breakage, abnormal vibration, and other malfunctions, paralyzing the entire transport system and causing equipment downtime. This not only affects production continuity and efficiency but also poses a threat to production safety. Utility Model Content

[0004] This application provides a water-cooled roller fixture for strip conveying, which aims to solve the technical problems in the prior art where rollers are prone to deformation under high temperature conditions, affecting their performance, and cooling water accelerates coupling damage and results in short coupling service life.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A water-cooled roller fixture for conveying strip and plate is provided, comprising:

[0007] The protective assembly includes a protective cylinder and a first bearing seat and a second bearing seat that rotate at both ends of the protective cylinder, the axis of the protective cylinder extending along a first path;

[0011] A water-cooling assembly is installed on the second bearing housing. The water outlet and water inlet of the water-cooling assembly are connected to the inner cavity of the protective cylinder and are used to deliver cooling water with a circulation path to the water-cooled roller.

[0012] In one possible implementation, a waterproof sleeve is formed at one end of the first bearing housing near the drive assembly, the coupling is placed inside the waterproof sleeve, and the axis of the waterproof sleeve overlaps with the rotation axis of the coupling, and the drive assembly is connected to the open end of the waterproof sleeve.

[0013] In one possible implementation, the coupling is keyed to the water-cooled roller; the top of the waterproof cylinder has a sealable screw plug hole, which communicates with the inner cavity of the waterproof cylinder, and a screw plug is installed in the screw plug hole, which is used to observe the working status of the coupling.

[0014] In one possible implementation, a first bearing is provided inside the first bearing housing, with the outer ring of the first bearing connected to the first bearing housing and the inner ring connected to the water-cooled roller.

[0015] In one possible implementation, a spacer ring is also fitted around the outer periphery of one end of the water-cooled roller connected to the coupling. One end of the spacer ring abuts against the end of the coupling, and the other end of the spacer ring abuts against one of the shaft end faces of the first bearing. The spacer ring is used to limit the displacement of the first bearing on the first path.

[0016] In one possible implementation, the water-cooling component includes:

[0017] A water conveying shaft is rotatably mounted on the second bearing seat. One end of the water conveying shaft extends into the protective cylinder and is connected to the protective cylinder. The water conveying shaft has an inlet channel and an outlet channel. The inlet channel and the outlet channel pass through the water conveying shaft along the first path. The outlet end of the inlet channel and the inlet end of the outlet channel are respectively connected to the inner cavity of the protective cylinder.

[0018] A water storage cylinder is installed on the side of the second bearing seat away from the first bearing seat. The other end of the water conveying shaft extends into the water storage cylinder. The inlet end of the water inlet channel and the outlet end of the water outlet channel are respectively connected to the water storage cylinder. A drain outlet is provided at the bottom of the water storage cylinder.

[0019] A water inlet pipe, one end of which passes sequentially through the water inlet channels of the water storage tank and the water conveying shaft along the first path, and communicates with the inner cavity of the protective cylinder; the water inlet pipe is rotatably connected to the water conveying shaft; and the other end of the water inlet pipe forms a water inlet; and

[0020] The water tank is connected to the water inlet and the water outlet respectively to form a water-cooled circulation path.

[0021] In one possible implementation, the top of the water storage cylinder has a viewing hole, and a transparent plate is installed inside the viewing hole.

[0022] In one possible implementation, a second bearing is rotatably mounted inside the second bearing housing, the second bearing being coaxially arranged with the first bearing, and the inner ring of the second bearing abutting against the outer periphery of the water conveying shaft;

[0023] A retaining washer is also provided between the second bearing housing and the water storage cylinder. The two ends of the retaining washer are respectively connected to the second bearing housing and the water storage cylinder, and the retaining washer is sleeved on the outer circumference of the water conveying shaft.

[0024] In one possible implementation, the protective cylinder is provided with two mounting seats spaced apart along the first path, and the two mounting seats are respectively connected to the water-cooled roller and the water conveying shaft.

[0025] In one possible implementation, two sealing rings are provided inside both ends of the protective cylinder. The two sealing rings are respectively fitted around the outer periphery of the water conveying shaft and the outer periphery of the water cooling roller to prevent cooling water from leaking out of the protective cylinder.

[0026] The water-cooled roller fixture for strip transport provided in this application, compared with the prior art, adds a protective component to the outer periphery of the water-cooled roller. The drive component drives the water-cooled roller to rotate, and the water-cooled roller and the protective cylinder rotate synchronously. The protective cylinder replaces the water-cooled roller in contact with the high-temperature strip. When the protective cylinder contacts the strip, the water-cooled roller absorbs the heat from the protective cylinder. Meanwhile, the water inlet end of the water-cooling component transports cooling water to the space where the water-cooled roller is located and makes direct contact with the water-cooled roller, absorbing and carrying away the heat from both the water-cooled roller and the protective cylinder. Combined with the existing forced cooling around the outer periphery of the protective cylinder, the temperature is reduced simultaneously from both inside and outside the protective cylinder, which can quickly and effectively reduce the temperature of the cooling roller and the protective cylinder, preventing the water-cooled roller from deforming due to excessively high temperatures affecting its structural strength. The coupling is placed inside the first bearing housing, isolated from the outside, preventing moisture from contacting the coupling, ensuring the dryness of the coupling, which is beneficial to extending the service life of the coupling and improving its reliability.

[0043] Please refer to the following: Figures 1 to 4 The apparatus for transporting the water-cooled roller 4 of a strip is described below. The apparatus for transporting the water-cooled roller 4 includes a protective assembly 1, a drive assembly 2, a coupling 3, the water-cooled roller 4, and a water-cooling assembly 5. The protective assembly 1 includes a protective cylinder 13 and a first bearing seat 11 and a second bearing seat 12, which rotate at opposite ends of the protective cylinder 13. The axis of the protective cylinder 13 extends along a first path. The drive assembly 2 is mounted on the first bearing seat 11. The coupling 3 is placed inside the first bearing seat 11. One end of the water-cooled roller 4 is inserted into the protective cylinder 13, and the other end rotates along a rotation axis parallel to the first path, engaging with the first bearing seat 11. The water-cooled roller 4 is connected to the output end of the drive assembly 2 via the coupling 3. The water-cooling assembly 5 is mounted on the second bearing seat 12. The outlet and inlet ends of the water-cooling assembly 5 communicate with the inner cavity of the protective cylinder 13, for supplying cooling water with a circulating path to the water-cooled roller 4.

[0044] It should be noted that the output end of the water-cooled roller 4 and the drive assembly 2 are connected by a coupling 3. The coupling 3 is existing technology, and its internal structure will not be described in detail here. The water-cooled roller 4 rotates with the output end. The water-cooled roller 4 is connected to the protective cylinder 13 and drives the protective cylinder 13 to rotate synchronously.

[0045] It should be noted that the forced cooling measures on the outer periphery of the water-cooled roller 4 in the prior art are forced water cooling, which is used in conjunction with the water cooling component 5 of this application to cool down from both the inner and outer sides of the protective cylinder 13.

[0046] It should be noted that the water-cooling component 5 can supply cooling water to the water-cooled roller 4 to reduce the temperature of the water-cooled roller 4, thereby avoiding problems such as reduced roller strength, cracking, and dimensional deviation caused by prolonged exposure to high-temperature working conditions, ensuring the normal operation of the transportation system, and improving production quality and efficiency.

[0047] The device for transporting the water-cooled roller 4 of the strip provided in this embodiment, compared with the prior art, adds a protective component 1 to the outer periphery of the water-cooled roller 4, and a driving component 2 drives the water-cooled roller 4 to rotate. The water-cooled roller 4 and the protective cylinder 13 rotate synchronously. The protective cylinder 13 replaces the water-cooled roller 4 in contact with the high-temperature strip. When the protective cylinder 13 contacts the strip, the water-cooled roller 4 absorbs the heat from the protective cylinder 13. Meanwhile, the water inlet end of the water-cooling component 5 transports cooling water to the space where the water-cooled roller 4 is located and makes direct contact with the water-cooled roller 4, absorbing and carrying away the heat from the water-cooled roller 4 and the protective cylinder 13. Combined with the existing forced cooling on the outer periphery of the protective cylinder 13, the temperature is reduced from both inside and outside the protective cylinder 13 at the same time, which can quickly and effectively reduce the temperature of the cooling roller and the protective cylinder 13, avoiding the impact of excessive temperature on the structural strength of the water-cooled roller 4, and preventing the water-cooled roller 4 from deforming. The coupling 3 is placed inside the first bearing seat 11 and isolated from the outside, preventing moisture from contacting the coupling 3, ensuring the dryness of the coupling 3, which is beneficial to extending the service life of the coupling 3 and improving the reliability of use.

[0048] In some embodiments, the drive assembly 2 includes a drive motor connected to the first bearing housing 11, and the drive motor has an output end. As the drive assembly 2, the drive motor provides stable power for the rotation of the water-cooled roller 4, ensuring smooth and efficient transport of the strip in the roller conveyor system, meeting the needs of industrial production. Specifically, the drive motor can be a rotary motor, or it can be a stepper motor or a brushless motor, as long as it can drive the coupling 3 to rotate.

[0049] In some embodiments, see Figure 1 and Figure 3 A waterproof sleeve 111 is formed at one end of the first bearing housing 11 near the drive assembly 2. The coupling 3 is placed inside the waterproof sleeve 111, and the axis of the waterproof sleeve 111 overlaps with the rotation axis of the coupling 3. The drive assembly 2 is connected to the open end of the waterproof sleeve 111. The protective space formed by the waterproof sleeve 111 prevents cooling water from splashing onto the coupling 3 during high-speed conveyor belt transport, avoids rusting of the coupling 3, prevents degradation of its mechanical properties, reduces the risk of transport system paralysis and equipment downtime due to coupling 3 failure, and ensures production continuity and safety.

[0050] In some embodiments, see Figure 1and Figure 3 The coupling 3 is keyed to the water-cooled roller 4. A sealable screw plug hole is provided at the top of the waterproof cylinder 111, communicating with the inner cavity of the cylinder. A screw plug 112 is installed inside the screw plug hole, which is used by employees to observe the working status of the coupling 3. The keyed connection between the coupling 3 and the water-cooled roller 4 ensures effective power transmission and improves transmission efficiency. The sealable screw plug hole facilitates inspection and maintenance of the protected space, allowing employees to observe the condition of the protected space and understand the working status of the coupling 3.

[0051] In some embodiments, see Figure 1 and Figure 3 The first bearing housing 11 houses the first bearing 113, with the outer ring of the first bearing 113 connected to the first bearing housing 11 and the inner ring connected to the water-cooled roller 4. The first bearing 113 supports the rotation of the water-cooled roller 4, reduces friction and resistance during rotation, makes the rotation of the water-cooled roller 4 more stable, ensures the stability of the strip transport, and improves production quality.

[0052] In a specific implementation, an inner end cap 114 is provided at the other end of the first bearing housing 11, and the inner end cap 114 blocks the end opening of the protective cylinder 13.

[0053] The inner end cap 114 can also block the first bearing 113 on the side of the first bearing seat 11, and fix the first bearing 113 on the first path in conjunction with the spacer ring 14 to prevent the first bearing 113 from shaking, which would cause the water-cooled roller 4 to work unstably.

[0054] In some embodiments, see Figure 1 and Figure 3 A spacer ring 14 is fitted around one end of the water-cooled roller 4 connected to the coupling 3. One end of the spacer ring 14 abuts against the end of the coupling 3, and the other end abuts against one of the shaft end faces of the first bearing 113. The spacer ring 14 is used to limit the displacement of the first bearing 113 on the first path. The spacer ring 14 can effectively limit the displacement of the first bearing 113 on the first path, ensure the stability of the position of the first bearing 113, and prevent the first bearing 113 from moving. This ensures the accurate relative position of the water-cooled roller 4 and the coupling 3, making the power transmission more stable and reliable, and further improving the operational stability of the device.

[0055] In some embodiments, see Figure 1 and Figure 2The water-cooling assembly 5 includes a water conveying shaft 51, a water storage tank 52, a water inlet pipe 53, and a water tank. The water conveying shaft 51 rotatably passes through the second bearing seat 12. One end of the water conveying shaft 51 extends into and connects to the protective cylinder 13. The water conveying shaft 51 has an inlet channel 511 and an outlet channel 512, which respectively pass through the water conveying shaft 51 along a first path. The outlet end of the inlet channel 511 and the inlet end of the outlet channel 512 are respectively connected to the inner cavity of the protective cylinder 13. The water storage tank 52 is installed on the side of the second bearing seat 12 facing away from the first bearing seat 11. The other end extends into the water storage cylinder 52, and the inlet end of the water inlet channel 511 and the outlet end of the water outlet channel 512 are respectively connected to the water storage cylinder 52. A drain outlet 523 is provided at the bottom of the water storage cylinder 52. One end of the water inlet pipe 53 passes through the water inlet channel 511 of the water storage cylinder 52 and the water conveying shaft 51 along the first path and is connected to the inner cavity of the protective cylinder 13. The water inlet pipe 53 is rotatably connected to the water conveying shaft 51, and the other end of the water inlet pipe 53 forms a water inlet. The water tank is connected to the water inlet and the drain outlet 523 respectively to form a water cooling circulation path.

[0056] It should be noted that a condenser is installed inside the water tank to cool the water, ensuring that the water entering the inner cavity of the protective cylinder 13 is low-temperature water, thus guaranteeing heat exchange and cooling of the water-cooled roller 4 and the protective cylinder 13. The installation of a condenser inside the water tank is a standard practice that can be performed by those skilled in the art based on existing technology; the specific structure of the condenser will not be described in detail here.

[0057] It should be noted that the water inlet pipe 53 is rotatably connected to the water conveying shaft 51, and the water conveying shaft 51 rotates synchronously with the protective cylinder 13.

[0058] It should be noted that the water inlet pipe 53 is inserted into the water inlet channel 511. It can be connected to the water conveying shaft 51 by interference fit, welding or snap-fit, so as to achieve coaxial and synchronous rotation.

[0059] In practical implementation, the water conveying shaft 51 has three channels running along its own long axis. The middle channel is the water inlet channel 511, and the other two are water outlet channels 512. See details... Figure 2 .

[0060] This embodiment provides a water-cooled assembly 5 with water circulation. Water enters the water conveying shaft 51 from the inlet of the water tank, and then flows into the protective cylinder 13 through the inlet channel 511 of the water conveying shaft 51. Cooling water contacts the water-cooled roller 4 and directly exchanges heat with it and the protective cylinder 13 for cooling. Once the inner cavity of the protective cylinder 13 is full, the cooling water moves from the outlet channel 512 on the water conveying shaft 51 to the storage cylinder 52, and then back into the water tank from the drain outlet 523 of the storage cylinder 52, thus forming a water circulation. Through the circulating movement of the cooling water, continuous cooling of the protective cylinder 13 and the water-cooled roller 4 is achieved, improving cooling efficiency. The water-cooled circulation path enables the recycling of cooling water, continuously cooling the water-cooled roller 4, effectively reducing its temperature, preventing problems such as roller cracking and deformation due to high temperatures, improving the service life and working performance of the water-cooled roller 4, and ensuring the normal operation of the belt conveyor system.

[0061] In some embodiments, see Figure 2 The top of the water storage cylinder 52 has a viewing hole 524, and a transparent plate is installed inside the viewing hole 524.

[0062] In some embodiments, see Figure 2 One end of the water storage cylinder 52 is sealed, and the other end is connected to a sealing cap 521. The sealing cap 521 is installed on the second bearing seat 12. The sealing cap 521 and the water storage cylinder 52 enclose a water-holding space, guiding water to flow out of the water conveying shaft 51 and into the water-holding space, and then out of the drain outlet 523, preventing water from overflowing from other gaps. The sealing cap 521 has a rotating hole that rotatably engages with one end of the water conveying shaft 51. A bushing 522 is installed between the rotating hole and the water conveying shaft 51, sealing the gap between the rotating hole and the water conveying shaft 51 to prevent cooling water from entering the second bearing seat 12.

[0063] Specifically, one end of the water storage tank 52 is blocked by the water inlet pipe 53, and an observation hole is provided at the top of the water storage tank 52 to facilitate employees to observe the water level inside the water storage tank 52 in order to control the flow rate of cooling water.

[0064] In some embodiments, see Figure 2 A second bearing 121 is rotatably mounted inside the second bearing housing 12. The second bearing 121 is coaxially arranged with the first bearing 113, and its inner ring abuts against the outer circumference of the water conveying shaft 51. A stop washer 15 is also provided between the second bearing housing 12 and the water storage tank 52. The two ends of the stop washer 15 are respectively connected to the second bearing housing 12 and the water storage tank 52, and the stop washer 15 is sleeved on the outer circumference of the water conveying shaft 51. The second bearing 121 can support the rotation of the water conveying shaft 51, making the water conveying process more stable. The stop washer 15 can prevent relative rotation between the water storage tank 52 and the second bearing housing 12, ensuring the stability of the water cooling assembly 5 structure, ensuring the normal operation of the water cooling circulation path, and improving the water cooling effect.

[0065] As one method of installing the first bearing 111 and the second bearing 121, lubricating oil is applied to the bearing housing and the bearing mating surfaces, the first bearing 111 is installed into the first bearing housing 11, and the second bearing 121 is installed into the second bearing housing 12, using a hammering method or a press assembly method.

[0066] In practice, anti-leakage washers 16 are provided on both sides of the first bearing 111 and both sides of the second bearing 121. Lubricating oil is injected into the first bearing 111 and the second bearing 121 during use to reduce friction. The anti-leakage washers 16 can intercept the lubricating oil and prevent leakage. The anti-leakage washers 16 can be lip seals.

[0067] In practice, the stop washer 15 is placed between the sealing cover 521 and the second bearing seat 12.

[0068] In some embodiments, see Figure 1 The protective cylinder 13 is equipped with two mounting seats 131 spaced apart along the first path. The two mounting seats 131 are respectively connected to the water-cooled roller 4 and the water conveying shaft 51. The mounting seats 131 can fix the positions of the water-cooled roller 4 and the water conveying shaft 51, making them more stable inside the protective cylinder 13. At the same time, they can make the protective cylinder 13, the water-cooled roller 4 and the water conveying shaft 51 rotate synchronously to transport the conveyor belt, ensuring that the rotation of the water-cooled roller 4 and the water conveying function of the water conveying shaft 51 are normal, thus improving the overall stability and reliability of the device.

[0069] In some embodiments, see Figure 1 The protective cylinder 13 is further equipped with two sealing rings 132 inside both ends. The two sealing rings 132 are respectively fitted around the outer circumference of the water conveying shaft 51 and the outer circumference of the water-cooled roller 4 to prevent cooling water from leaking out of the protective cylinder 13. The sealing rings 132 can prevent cooling water from leaking out of both ends of the protective cylinder 13, ensuring that the cooling water of the water-cooling assembly 5 can effectively act on the water-cooled roller 4, improving the water cooling efficiency, while avoiding the impact of cooling water leakage on surrounding equipment and the environment, ensuring the normal operation of the transportation system and the safety of the production environment.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
