Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical rolling mill machinery technology, specifically a telescopic guide plate platform guiding device. Background Technology
[0002] In cold-rolled strip continuous annealing and finishing production lines, a "double uncoiler, double coiler" system is often used to accelerate production and improve efficiency. When one uncoiler or coiler malfunctions, the other takes over to ensure continuous operation of the production line. Due to space constraints, uncoilers (coils) are typically designed with a layered layout to avoid interference between equipment. To ensure a compact equipment layout, telescopic guide plates are the preferred strip guiding device.
[0003] Existing telescopic guide plates mostly adopt a sliding rail type guide structure. The sliding rail mechanism has high planar friction, and the track surface is easily worn. Moreover, due to the harsh working environment, dust, iron filings and other debris fall onto the sliding rail, causing severe wear and reduced guiding accuracy. This often leads to jamming and damage of the guide plate. Therefore, there is an urgent need for a telescopic guide plate guide device to solve the above problems. Utility Model Content

[0008] The beneficial effects of this utility model are:
[0009] The telescopic guide plate platform guide device, due to the guiding effect of the bidirectional rollers, ensures that the belt rollers always move in parallel, thus preventing the conveyed steel strip from deviating. The modular design of the bidirectional rollers of the guide device allows for group replacement, has a simple structure, and is convenient for offline maintenance. The bidirectional rollers have low rolling friction resistance, are not prone to jamming, and have high guiding accuracy, which is of practical significance in preventing steel strip from deviating.

A guide rail groove is opened inside the guide plate, and the bidirectional roller is slidably connected to the inside of the guide rail groove.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the guide rail frame and guide plate configuration provides a stable guide rail groove for the bidirectional roller, ensuring the guiding accuracy of the bidirectional roller during the movement process and reducing deviation and wear.
[0013] Furthermore, a front hinge seat is fixedly connected inside the swing frame, a moving oil cylinder is hinged inside the front hinge seat, a rear hinge seat is hinged to the output end of the moving oil cylinder, and a belt roller connecting bracket is fixedly connected to the end of the rear hinge seat away from the moving oil cylinder.
[0014] Furthermore, the belt roller connecting bracket is fixedly connected to the bracket side plate, and a support beam is fixedly connected to the inner wall of the swing frame. There are two support beams, and the moving oil cylinder is fixedly installed inside the support beam.

[0016] Furthermore, the bidirectional rollers are arranged in pairs, with a total of four groups, each containing two bidirectional rollers.
[0017] The beneficial effect of adopting the above-mentioned further scheme is that by setting four sets of bidirectional rollers, two in each set, they can be more evenly distributed in the guide rail groove, thereby improving the guiding accuracy and stability of the guiding device.
[0018] Furthermore, the swing frame is internally rotatably connected to a belt roller, and the support side plate is internally rotatably connected to a movable belt roller.

[0025] 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.
[0026] In the embodiments, by Figure 1-4 A telescopic guide plate platform guiding device is provided. This utility model includes a swing frame 2 and a support side plate 12. A bidirectional roller 10 is assembled inside the support side plate 12. The bidirectional roller 10 includes a connecting plate 13 fixedly connected to the inside of the support side plate 12 by bolts 14. A connecting sleeve 104 is interference-fitted inside the connecting plate 13 and continuously welded around the inner wall of the hole. A longitudinal roller 101 is assembled outside the connecting sleeve 104. The outer diameter of the connecting sleeve 104 is designed with a specific position for installing the longitudinal roller 101. The longitudinal roller 101 is rotatably connected to the connecting sleeve 104. A roller shaft 103 is rotatably connected inside the connecting sleeve 104. A transverse roller 102 is fixedly connected to the outside of the roller shaft 103. A pressure cap 105 is fixedly connected to the end of the connecting sleeve 104. The pressure cap 105 is set to ensure that the longitudinal roller 101 can rotate freely but will not loosen. The inside of the pressure cap 105 has an movable opening adapted to the transverse roller 102.
[0027] Specifically, refer to Figure 2 The swing frame 2 is fixedly connected to the guide rail frame 3. The guide rail frame 3 is fixedly connected to the side plate 12 of the support frame 12. The guide rail groove is opened inside the guide plate 11. The bidirectional roller 10 is slidably connected to the inside of the guide rail groove. The bidirectional roller 10 is arranged in pairs, with a total of four sets, each set containing two bidirectional rollers 10.
[0028] In this embodiment, in actual use, the guide rail frame 3 and guide plate 11 provide a stable guide rail groove for the bidirectional roller 10, ensuring the guiding accuracy of the bidirectional roller 10 during movement, reducing deviation and wear. By setting four sets of bidirectional rollers 10, two in each set, they can be more evenly distributed in the guide rail groove, thereby improving the guiding accuracy and stability of the guiding device. The configuration of multiple sets of bidirectional rollers 10 can better distribute the load, reduce the force on a single roller, and extend the service life of the equipment.
[0029] Specifically, refer to Figure 1 The swing frame 2 is fixedly connected to a front hinge seat 6. A movable cylinder 5 is hinged inside the front hinge seat 6. A rear hinge seat 8 is hinged to the output end of the movable cylinder 5. A belt roller connecting bracket 9 is fixedly connected to the end of the rear hinge seat 8 away from the movable cylinder 5. The belt roller connecting bracket 9 is fixedly connected to the side plate 12 of the bracket. A support beam 7 is fixedly connected to the inner wall of the swing frame 2. There are two support beams 7. The movable cylinder 5 is fixedly installed inside the support beam 7.
[0030] In this embodiment, the support beam 7 can enhance the structural strength of the swing frame 2 in actual use, ensuring that it will not deform or be damaged when subjected to a large load. Fixing the moving cylinder 5 inside the support beam 7 can ensure the stability of the cylinder during operation and reduce damage to the cylinder caused by vibration or impact.
[0031] Specifically, refer to Figure 4 The swing frame 2 is equipped with a tension roller assembly. A belt roller 1 is rotatably connected inside the swing frame 2. A movable belt roller 4 is rotatably connected inside the support side plate 12. The tension roller assembly is a conventional setup for those skilled in the art and is not the focus of this application. Therefore, it is only briefly described. The tension roller assembly includes a transmission roller set inside the support side plate 12. The swing frame 2 is also equipped with three tension rollers. Two of the tension rollers are fixed inside the swing frame 2 by bearing seats. An adjusting rod is set on the bearing seat of each tension roller. The adjusting rod passes through the swing frame 2. Two fastening nuts are set at the connection between the adjusting rod and the swing frame 2, thereby achieving the purpose of adjusting the belt tension.
[0032] In this embodiment, in actual use, through reasonable arrangement, the belt passes around the belt roller 1, the movable belt roller 4, the transmission roller and three tension rollers in sequence. The motor is set on the back of the swing frame 2, and the output shaft of the motor is fixedly connected to the belt roller 1. This can ensure the stability of the belt during the movement, reduce belt vibration and deviation, and thus improve the overall operational stability of the equipment.
[0033] In this embodiment, in actual use, the swing frame 2 has a frame structure, with the two sides connected by two middle support beams 7. A stainless steel plate is laid on the support beams 7, and the upper surface of the stainless steel plate is set horizontally with the strip steel through line. The swing frame 2 is the load-bearing structure of the telescopic guide plate platform. The front end of the swing frame 2 is rotatably connected to the steering roller support. The swing frame 2 can swing around the steering roller. The swing cylinder is rotatably connected to the swing frame 2 through a rotatable setting. The swing cylinder is used to rotate the swing frame 2 to ensure that the strip steel through direction is tangent to the outer diameter of the drum. The moving cylinder 5 is driven, and the cylinder pushes the bracket side plate 12 to drive the movable belt roller 4 to extend to the drum.
[0034] Working principle:
[0035] According to the position of the coiler drum, the swing cylinder pushes the swing frame 2 to rotate, ensuring that the strip steel passing direction is tangent to the outer diameter of the drum. After the angle of the swing frame 2 is adjusted, the moving cylinder 5 is driven. The cylinder pushes the bracket side plate 12 to drive the movable belt roller 4 to extend to the drum. The strip steel enters the swing frame 2, and the belt on the movable belt roller 4 sends the strip steel to the drum inlet. After the coiler assist wraps the strip steel 3 times, the coiler speeds up and coils normally. Due to the guiding effect of the four sets of bidirectional rollers, the moving direction of the belt roller is always consistent with the moving direction of the strip steel, which effectively prevents the strip steel from deviating and ensures that the strip steel is threaded smoothly.
