Description

Technical Field

[0001] This application relates to the technical field of metal cold-rolled sheet processing, and particularly to a guide roll driving device. Background Art

[0002] Cold rolling is processed on the basis of hot-rolled coils. Generally speaking, the processing process is hot rolling, pickling, phosphating, saponification, and cold rolling. In a cold-rolled strip production line, the guide roll is a key component, which is usually used in equipment such as cold rolling mills, continuous annealing lines, coating lines, and tension leveling machines to ensure the accurate positioning and stable transportation of the sheet during the processing.

[0003] Currently, the cold rolling mill equipment includes a threading platform, and the strip is transported to the strip coiler after passing through the threading platform. A guide roll is provided at the end of the threading platform, and the guide roll is placed horizontally. Since the height of the strip coiler is different from that of the threading platform, the guide roll serves as a transition to facilitate the smooth transportation of the strip to the coiler.

[0004] Since the guide roll is passive and relies on the movement of the strip to drive its rotation, during the transportation of the strip, the starting end of the strip will poke at the surface of the guide roll, resulting in damage to the surface of the guide roll by the strip. After a certain degree of damage to the guide roll, it needs to be shut down for replacement, increasing the cost. Summary of the Utility Model

[0005] In order to reduce the possibility of damage to the guide roll, the present utility model provides a guide roll driving device.

[0006] The guide roll driving device provided by the present utility model adopts the following technical solution:

[0007] A guide roll driving device includes a driving member and a driving assembly. The driving member is connected to the ground. The driving assembly is arranged below the guide roll. The driving assembly includes a motor and a driving roll. The motor is connected to the driving member. The driving member can drive the motor to move away from or close to the guide roll. When the driving roll is in contact with the guide roll, the driving roll can drive the guide roll to rotate along the moving direction of the strip.

[0008] By adopting the above technical solution, during use, by controlling the driving member, it drives the motor and the driving roller to move towards the guiding roller until the driving roller abuts against the guiding roller. At this time, start the motor, and the driving shaft of the motor drives the driving roller to rotate, and then drives the guiding roller to rotate along the moving direction of the strip steel. During the process when the strip steel approaches and gradually contacts the guiding roller, if the guiding roller does not move and the strip steel moves, due to inertia, the strip steel will directly impact the surface of the guiding roller. Therefore, when the guiding roller rotates along the moving direction of the strip steel, the guiding roller drives the strip steel to continue moving, reducing the impact force between the guiding roller and the strip steel, reducing the possibility of damage to the guiding roller, and at the same time, the strip steel moves more smoothly, reducing the phenomenon of the strip steel getting stuck. When it is necessary to stop driving the guiding roller, only need to control the driving member to move the motor and the driving roller away from the guiding roller.

[0009] Preferably, a fixing plate is arranged between the motor and the driving member. One end of the fixing plate is hinged to the steel structure of the threading platform. The motor is connected to the top of the fixing plate, and the driving member is hinged to the bottom of the fixing plate.

[0010] By adopting the above technical solution, the motor and the driving roller can swing with the hinge part of the fixing plate as the fulcrum, so as to realize the abutment or separation of the driving roller and the guiding roller, and increase the stability of the movement of the motor and the driving roller.

[0011] Preferably, a base is hinged to the bottom end of the driving member, and the base is fixedly connected to the ground.

[0012] By adopting the above technical solution, the bottom end of the driving member can rotate, and the bottom end can also rotate, so as to realize the pushing of the hinge of the fixing plate.

[0013] Preferably, the base is fixedly connected to the ground by bolts.

[0014] By adopting the above technical solution, if the base, cylinder, etc. need to be replaced and overhauled, the bolt-fixed base is convenient for disassembly.

[0015] Preferably, the driving member adopts a cylinder.

[0016] Preferably, the motor is fixedly connected to the fixing plate by bolts.

[0017] By adopting the above technical solution, when the motor fails, it is convenient for the quick disassembly and assembly of the motor.

[0018] Preferably, it further includes a safety plate and a safety insertion rod. The top end of the safety plate is fixedly connected to the steel structure of the tape threading platform. A jack is provided on the fixed plate, and a first fixing hole and a second fixing hole are provided on the safety plate. When overhauling the driving device, if the driving roller abuts against the guiding roller, the first fixing hole is aligned with the jack, and the safety insertion rod passes through the first fixing hole and is inserted into the jack to limit the fixed plate. If the driving roller moves away from the guiding roller, the second fixing hole is aligned with the jack, and the safety insertion rod passes through the second fixing hole and is inserted into the jack to limit the fixed plate.

[0019] By adopting the above technical solution, whether the driving roller and the guiding roller are in contact or not, when overhauling the driving device, the safety plate and the safety insertion rod cooperate to limit the fixed plate, reducing the accidental movement of the cylinder and the motor, thus preventing the situation that affects the overhaul of the entire device, and further improving the safety and stability of the device.

[0020] Preferably, a thread is provided on the circumferential wall of the safety insertion rod, and the safety insertion rod is threadedly connected to the fixed plate.

[0021] By adopting the above technical solution, during the process of overhauling the driving device, through the thread setting, the stability of the safety insertion rod and the fixed plate is increased, and the stability of the motor and the driving roller is increased.

[0022] Preferably, a handle for easy taking is fixedly connected to one end of the safety insertion rod. A convex block is connected to the side wall of the fixed plate, and a placement hole for placing the safety insertion rod is vertically opened at the top of the convex block, and the safety insertion rod is inserted into the placement hole.

[0023] By adopting the above technical solution, when the driving device is not overhauled and the safety insertion rod is not used, it can be inserted into the placement hole for storage.

[0024] Preferably, the driving roller is made of steel-lined rubber material.

[0025] By adopting the above technical solution, the driving roller made of steel-lined rubber material not only ensures the strength of the driving roller, but also improves its wear resistance and service life. At the same time, it effectively reduces the wear of the guiding roller.

[0026] In summary, the utility model has the following beneficial effects:

[0027] 1. During use, by controlling the driving member, it drives the motor and the driving roller to move towards the guiding roller until the driving roller abuts against the guiding roller. At this time, start the motor, and the driving shaft of the motor drives the driving roller to rotate, thereby driving the guiding roller to rotate along the moving direction of the strip steel. During the process when the strip steel approaches and gradually contacts the guiding roller, if the guiding roller does not move and the strip steel moves, due to inertia, the strip steel will directly impact the surface of the guiding roller. Therefore, when the guiding roller rotates along the moving direction of the strip steel, the guiding roller drives the strip steel to continue moving, reducing the impact force between the guiding roller and the strip steel, reducing the possibility of damage to the guiding roller, and at the same time, the strip steel moves more smoothly and reduces the phenomenon of the strip steel getting stuck.

[0028] 2. The combination of the safety plate and the safety insertion rod can limit the fixed plate in two states where the driving roller abuts against or is away from the guiding roller during the maintenance of the driving device, reducing the accidental movement of the cylinder and the motor, thereby improving the safety and stability of the device.

[0033] The following further elaborates on the present utility model with reference to the accompanying drawings.

[0034] A guiding roller driving device, referring to Figure 1 , includes a driving member and a driving assembly, and the driving member is connected to the ground. The driving assembly is arranged below the guiding roller, and the driving assembly includes a motor 5 and a driving roller 6. The motor 5 is connected to the driving member, and the driving member can drive the motor 5 to move away from or close to the guiding roller. The driving roller 6 is vertically arranged, and the driving roller 6 is fixedly connected to the driving shaft of the motor 5. When the circumferential wall of the driving roller 6 abuts against the circumferential wall of the guiding roller, the driving roller 6 can drive the guiding roller to rotate along the moving direction of the strip steel.

[0035] During use, by controlling the driving member, it drives the motor 5 and the driving roller 6 to move towards the guiding roller until the driving roller 6 abuts against the guiding roller. At this time, the motor 5 is started, and the driving shaft of the motor 5 drives the driving roller 6 to rotate, thereby driving the guiding roller to rotate along the moving direction of the strip steel. During the process that the strip steel approaches and gradually contacts the guiding roller, if the guiding roller does not move and the strip steel moves, due to inertia, the strip steel will directly impact the surface of the guiding roller. Therefore, when the guiding roller rotates along the moving direction of the strip steel, the guiding roller drives the strip steel to continue moving, reducing the impact force between the guiding roller and the strip steel, reducing the possibility of damage to the guiding roller, and at the same time, the strip steel moves more smoothly and the phenomenon of the strip steel getting stuck is reduced.

[0036] Refer to Figure 1 , the driving member adopts a cylinder 3, a hydraulic cylinder, etc. In this embodiment, the driving member adopts a cylinder 3. The bottom end of the cylinder 3 is hinged with a base 2, and the base 2 is fixedly connected to the ground through bolts.

[0037] Refer to Figure 1 , a fixing plate 4 is arranged between the motor 5 and the driving member. One end of the fixing plate 4 is hinged with the steel structure of the strip threading platform 1. The motor 5 is fixedly connected to the top of the fixing plate 4 through bolts, and the top end of the cylinder 3 is hinged with the bottom of the fixing plate 4.

[0038] The motor 5 and the driving roller 6 can swing with the hinge part of the fixing plate 4 as a fulcrum, so as to realize abutting against or moving away from the guiding roller. The stability of the movement of the motor 5 and the driving roller 6 is increased.

[0039] Refer to Figure 2 , the driving roller 6 is made of a steel-lined rubber material. This material combines the strength of steel and the wear resistance of rubber, not only ensuring the service life of the driving roller 6, but also effectively reducing the wear on the guiding roller.

[0040] Refer to Figure 1 , the guiding roller driving device further includes a safety plate 7 and a safety insertion rod 8. The safety plate 7 is vertically arranged, and the top end of the safety plate 7 is fixedly connected to the steel structure of the strip threading platform 1. A convex block 42 is fixedly connected to the side wall of the safety plate 7. A placement hole is vertically opened at the top of the convex block 42, and the safety insertion rod 8 is inserted into the placement hole. A handle 81 is fixedly connected to the top end of the safety insertion rod 8.

[0041] When the driving device is not overhauled, the safety insertion rod 8 is not used and can be inserted into the placement hole for storage.

[0042] Refer to Figure 1 and Figure 2, a jack 41 is formed on the fixed plate 4, and a first fixing hole 71 and a second fixing hole 72 are formed on the safety plate 7. When overhauling the driving device, if the driving roller 6 abuts against the guiding roller, the first fixing hole 71 is aligned with the jack 41, and the safety plug 8 passes through the first fixing hole 71 and is inserted into the jack 41 to limit the safety plate 7 to the fixed plate 4. If the driving roller 6 moves away from the guiding roller, the second fixing hole 72 is aligned with the jack 41, and the safety plug 8 passes through the second fixing hole 72 and is inserted into the jack 41 to limit the safety plate 7 to the fixed plate 4.

[0043] Whether the driving roller 6 and the guiding roller are in contact or not, when overhauling the driving device, the safety plate 7 and the safety plug 8 cooperate to limit the fixed plate 4, reduce the extension or retraction of the driving shaft of the cylinder 3, and further affect the motor 5 and the driving roller 6, thereby increasing the stability of the entire driving device.

[0044] Refer to Figure 1 , the outer circumference of the safety plug 8 is provided with threads. When the safety plug 8 is inserted into the jack 41, the safety plug 8 is threadedly connected to the safety plate 7 and the safety plug 8 is threadedly connected to the fixed plate 4.

[0045] During the process of overhauling the driving device, the stability of the motor 5 and the driving roller 6 is increased by increasing the stability of the safety plug 8 and the fixed plate 4.

[0046] The working principle of the present application is as follows: during use, by controlling the cylinder 3, the fixed plate 4 is driven to rotate along its own hinge part, and the fixed plate 4 drives the motor 5 and the driving roller 6 to move towards the guiding roller until the driving roller 6 abuts against the guiding roller. At this time, the motor 5 is started, and the driving shaft of the motor 5 drives the driving roller 6 to rotate, thereby driving the guiding roller to rotate along the moving direction of the strip steel, reducing the impact force between the guiding roller and the strip steel, reducing the possibility of damage to the guiding roller, and at the same time, the strip steel moves more smoothly, reducing the phenomenon of the strip steel getting stuck.

[0047] When it is necessary to stop driving the guiding roller, only the cylinder 3 needs to be controlled to move the motor 5 and the driving roller 6 away from the guiding roller.
