Description

Technical Field

[0001] This utility model belongs to the field of continuous cold rolling annealing unit production, and particularly relates to a storage and sorting device for nylon tape threading in continuous annealing units. Background Technology

[0002] A continuous cold rolling annealing unit is a production line for cold-rolled steel sheets. It typically consists of multiple continuous processes, including annealing, cold rolling, and coating. These processes, coordinated by mechanical equipment and an automatic control system, enable continuous processing of the steel sheet. The steel sheet undergoes heat treatment in an annealing furnace to improve its mechanical properties and deformability. After cold rolling, the steel sheet can be coated to increase its corrosion resistance, surface resistivity, and aesthetics. The advantages of a continuous cold rolling annealing unit include high production efficiency, the ability to continuously process large quantities of strip steel, and high processing precision and surface quality. It plays a vital role in the steel manufacturing and processing industry and is widely used in various industrial fields. When producing strip steel with a thickness of less than 0.3 mm, continuous annealing units are prone to strip breakage accidents due to defects such as edge cracks and substandard weld quality in the cold-rolled strip. Continuous annealing units have relatively long process sections, including looper sections, cleaning sections, and annealing furnaces. In the event of a strip breakage accident, multiple nylon straps with a length of over 50 meters are needed to thread the strip and handle the incident. Due to their length and weight, transport requires overhead cranes. Furthermore, the nylon bags are often misplaced during storage, leading to folds in the nylon strapping when it is unrolled. These folds must be addressed before threading the strapping, increasing threading time. Furthermore, folds in the nylon strapping during threading can cause the strip to become stuck in the strip channel, resulting in a secondary breakage and extending the overall time required to handle the incident. Summary of the Invention

[0003] The purpose of this invention is to provide a storage and sorting device for nylon tape in continuous roll forming units, which enables rapid sorting of nylon tape and quick release when tape breaks during use, avoiding folding of the nylon tape, reducing tape-making time, and preventing secondary tape breakage caused by folding of the nylon tape during use.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A storage and organizing device for threading nylon tape in a continuous annealing unit includes a trolley, a support mechanism, a winding disc, a rotating shaft, a motor, a belt, a drive wheel, and a driven wheel. The support mechanism is fixedly connected to the trolley. The rotating shaft is connected to the support mechanism via bearings and is fixedly connected to the winding disc. The drive wheel and the driven wheel are connected via a belt, and the driven wheel is fixedly connected to the rotating shaft. The motor drives the drive wheel to rotate. The winding disc includes a fixed disc, which is fixedly connected to the rotating shaft.

[0006] The trolley includes fixed casters, movable casters, a trolley body, and a push handle. The trolley body is a flat structure. The fixed casters and movable casters are connected to the bottom of the trolley body, with the fixed casters located at the front and the movable casters located at the rear. A push handle is fixedly connected to the upper rear of the trolley body. Both the fixed casters and movable casters are connected to a brake structure.

[0007] The motor is fixed on the trolley.

[0008] The winding disc also includes an adjusting disc, which is disposed between the two fixed discs.

[0009] The adjusting disc and the rotating shaft are connected by adjusting screws.

[0010] The rotating shaft is provided with several mounting holes along the axial direction.

[0011] The fixed disk and the rotating shaft are fixedly connected by bolts.

[0012] The support mechanism includes a fixed seat, an upper bearing cover, and a lower bearing cover. The fixed seat is fixedly connected to the trolley, and the top of the fixed seat is fixedly connected to the lower bearing cover. The upper bearing cover and the lower bearing cover are fixedly connected by bolts. Both the upper bearing cover and the lower bearing cover are semi-circular ring structures. The upper bearing cover and the lower bearing cover are connected to the rotating shaft through bearings.

[0013] The end of the rotating shaft is fixedly connected with a key, and the driven wheel is connected to the rotating shaft through the key.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model facilitates the transportation, storage, and organization of nylon tapes. It allows for the storage and unloading of nylon tapes in confined spaces, reducing manpower and saving time on tape threading. It also reduces the threading time of continuous winding units, improves threading efficiency, and minimizes losses caused by unplanned downtime. A motor-driven winding disc enables rapid organization of the nylon tapes and allows for quick release after tape breakage, preventing folding during handling and significantly reducing threading time. It also prevents secondary tape breakage caused by folding during threading. The winding and storage of nylon tapes are completed simultaneously with threading. Previously, after threading, dedicated personnel were needed to store and organize the nylon tapes, affecting the speed of production recovery. This new design saves manpower during winding and allows limited workers to focus on resuming production.

[0016] 2. The winding reel features an adjustable structure. Adjusting the distance between the fixed and adjusting reels allows for customization based on the nylon tape width, preventing the tape from folding due to using the wrong reel. This adjustable structure allows for winding nylon tape of various widths, making it a versatile reel for multiple uses.

[0017] 3. This utility model uses a trolley for easy transport. During transportation, the trolley can be pushed to facilitate transport to the warehouse, improving warehouse management efficiency. Simultaneously, the trolley can also carry replacement winding trays, further enhancing work efficiency.

[0018] 4. The support mechanism adopts a split-structure bearing cover, which can improve the speed of changing the winding disc, thereby improving work efficiency and shortening the threading time. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0027] See Figures 1-5 A storage and organizing device for nylon tape threading in a continuous annealing machine includes a trolley, a support mechanism, a winding reel, a rotating shaft 4, a motor 5, a belt 6, a drive wheel 7, and a driven wheel 8. The support mechanism is fixedly connected to the trolley. The rotating shaft 4 is connected to the support mechanism via bearings and is also fixedly connected to the winding reel. The drive wheel 7 and driven wheel 8 are connected via the belt 6, and the driven wheel 8 is fixedly connected to the rotating shaft 4. The motor 5 drives the drive wheel 7 to rotate, which in turn drives the driven wheel 8 via the belt 6, thus rotating the winding reel. To replace the winding reel, the belt 6 must first be disengaged, then the end cap of the driven wheel 8 must be removed, and finally the driven wheel 8 must be removed to replace the winding reel. A key 3 is fixedly connected to the end of the rotating shaft 4, and the driven wheel 8 is connected to the rotating shaft 4 via the key 3. Figure 6The winding reel includes a fixed plate 12, which is fixedly connected to the rotating shaft 4 by bolts 17. The position between the two fixed plates 12 is used for winding the nylon tape, and the fixed plates 12 are used to define the winding position of the nylon tape. The motor 5 is fixed on the trolley. The motor 5 is a reversible motor, which can assist in feeding or winding the nylon tape by reversing the direction of rotation.

[0028] See Figures 1-5 The trolley adopts a push handle and a flatbed body 1. The trolley includes fixed casters 10, movable casters 11, the body 1, and a push handle 9. The body 1 is a flatbed structure. The fixed casters 10 and movable casters 11 are connected to the bottom of the body 1, with the fixed casters 10 located at the front and the movable casters 11 at the rear. The push handle 9 is fixedly attached to the upper rear of the body 1, enabling the trolley to turn. Both the fixed casters 10 and movable casters 11 are equipped with brakes, which lock when the nylon strap is retracted or extended to prevent the trolley from moving.

[0029] The rotating shaft 4 has several mounting holes 14 along its axial direction. (See...) Figure 3 An adjusting disc 13 is also connected to the winding reel. The adjusting disc 13 is positioned between the fixed discs 12. The adjusting disc 13 is connected to the rotating shaft 4 via threaded pins and mounting holes 14 (threaded). By installing the threaded pins in different mounting holes, the position of the adjusting disc 13 can be adjusted, allowing the same winding reel to wind nylon tape of different widths. When the adjusting disc 13 is installed in the leftmost mounting hole (at which point the original left fixed disc 12 can be removed), it can wind the widest specification of nylon tape.

[0030] An adjusting disc 13 is installed on the non-drive side of the winding reel. The distance between the adjusting disc 13 and the fixed disc 12 can be adjusted according to the width of the nylon tape. After adjustment to the corresponding width, it is fixed with threaded pins, which can effectively prevent the nylon tape from moving axially during winding and unwinding. Since different widths of nylon tape are used for threading in different parts of the site, the winding reel can be made into a separate reel for each width of nylon tape through this structural design, reducing the number of spare parts. If the wrong winding reel is used due to communication problems, the width can be adjusted by removing and installing the pins, reducing the threading time and preventing the nylon tape from folding due to width mismatch.

[0031] The support mechanism includes a fixed base 2, an upper bearing cover 15, and a lower bearing cover 16. The bottom of the fixed base 2 is welded and fixed to the trolley. The fixed base 2 adopts a structure that is smaller at the top and larger at the bottom, allowing the winding reel to work stably on the trolley. The upper part of the fixed base 2 and the winding reel adopt a semi-enclosed quick-release structure, that is, the top of the fixed base 2 is fixedly connected to the lower bearing cover 16, and the upper bearing cover 15 and the lower bearing cover 16 are fixedly connected by bolts. Both the upper bearing cover 15 and the lower bearing cover 16 are semi-circular ring structures, and the upper bearing cover 15 and the lower bearing cover 16 are connected to the rotating shaft 4 through a bearing. Replacing the winding reel only requires removing the bolts between the upper bearing cover 15 and the lower bearing cover 16, which allows for quick replacement of the winding reel. This facilitates the replacement of the next winding reel after winding and unwinding one roll of nylon tape, eliminating the need for a trolley for each winding reel. The removed winding reel can also be rolled and pushed or placed on a flatbed cart for transportation, improving tape threading efficiency.

[0032] See Figures 1-5 For initial use, tie the end of the nylon tape to the core of the winding reel with a thin rope. Then, one person unfolds the pleats of the nylon tape while another person controls the rotation of the winding reel to take it up. When releasing the nylon tape, remove the belt 6 and let it rotate passively. When retracting the nylon tape after threading, use motor 5 for assisted winding. The motor 5 winds the tape synchronously with the tension roller, so that the nylon tape is also neatly arranged when the threading is finished. At the same time, electric winding reduces manpower.

[0033] When a strip breaks on the continuous annealing unit, the broken strip is first removed from the process section. Then, a trolley is pushed to the site and locked. Motor 5 rotates, causing the nylon strip on the winding reel to be manually threaded through the process section. This ensures that the nylon strip itself does not fold during threading, eliminating the need to deal with folds and saving time. Finally, the lock is released, and the trolley and empty winding reel are transported out of the section. The width of the winding reel is adjusted according to the width of the nylon strip. While threading the strip with the tension roller, belt 6 is placed between the drive pulley 7 and the driven pulley 8, and the nylon strip is wound up under the drive of motor 5. After winding one reel of nylon strip, the width of the winding reel is adjusted according to the width of the next reel of nylon strip until the strip head reaches the end of the process section, and the ends of the broken strip are welded together. The unit resumes production after running at low tension to the winding machine.

[0034] This invention facilitates the transportation, storage, and organization of nylon tapes. It allows for the unloading and loading of nylon tapes in confined spaces, reducing manpower and saving time on tape threading. It also reduces the threading time of continuous winding units, improves threading efficiency, and minimizes losses caused by unplanned downtime. A motor drives the winding disc to rotate, enabling rapid organization of the nylon tapes and quick release after tape breakage, avoiding kinking during handling and significantly reducing threading time. It also prevents secondary tape breakage caused by kinking during threading. The winding and storage of nylon tapes are completed simultaneously with threading. Previously, after threading, dedicated personnel were needed to collect and organize the nylon tapes, affecting the speed of production recovery. This invention saves manpower during winding and allows limited workers to focus on resuming production.
